A rope displacement sensor for measuring and winding separately

Release date: June 23, 2019 Hits: 84

Existing pull rope Displacement sensor The design is that the pull wire winding mechanism and the measuring mechanism are integrated. The winding must be arranged on the winding wheel in a single layer. The arrangement order will bring the error of axis and swing angle, which will directly affect the length and accuracy of measurement. Moreover, the existing pull rope Displacement sensor The installation of the stay wire is troublesome. There is no indication device, so the vertical installation of the stay wire can not be guaranteed, which increases the measurement error caused by the installation.

summary of the invention

In order to overcome the defects of the prior art, the invention provides a measurement and winding separation device Rope displacement sensor The measurement mechanism is completely separated from the winding mechanism, which completely eliminates the axial error and winding swing angle error caused by the winding mechanism; the measuring wheel is directly driven to rotate by the wire rope, and the measurement accuracy is greatly improved without other conversion mechanism.

In order to achieve the above purpose, the technical scheme of the invention is as follows:

A separate measuring and winding device Rope displacement sensor The measuring unit is separated from the winding mechanism, the measuring unit comprises a measuring wheel and an angular displacement sensor, the winding mechanism comprises a winding wheel and a bearing, the steering mechanism comprises a guide wheel and a steering wheel, and a stay wire on the winding wheel passes through the guide wheel and winds to the measuring wheel and turns through the steering wheel. The shell is a double-layer structure, the guide wheel and measuring wheel are located at the upper layer of the shell, the winding wheel and bearing are located at the lower layer of the shell, the upper and lower layers are connected by the steering wheel, and the stay wire is wound from the upper layer of the shell to the lower layer through the steering wheel. The shell can also be a single-layer structure, and the guide wheel, steering wheel, measuring wheel, winding wheel and bearing are all located on the shell. The measuring unit is composed of a measuring wheel, an angular displacement sensor and a bottom plate. The angular displacement sensor is fixed on the bottom plate, and the bottom plate is fixed on the shell by screws; A shaft is arranged on the angular displacement sensor, which is fixed with the measuring wheel through a jacking screw. When the measuring wheel rotates, the shaft on the angular displacement sensor also rotates. The angular displacement sensor converts the displacement signal into an electrical signal that can be read for communication, transmission, etc.

Furthermore, the winding mechanism is composed of a winding wheel, a winding wheel, a bearing, a spring, a spring box, a spring mandrel and a fixed shaft. The spring mandrel is connected with the winding wheel as a whole through bolts. The spring is placed in the spring box, and one end is connected with the spring box, and the other end is connected with the spring core shaft. The spring box is fixed on the shell by screws. The spring mandrel and the winding wheel are fixed and connected by screws to form a whole body. The winding wheel is connected with the fixed shaft through a bearing and can rotate freely on the fixed shaft. The fixed shaft is connected with the shell through screws. The wire arranging wheel is an automatic wire arranging wheel, which is fixed on the shell through the pin shaft, so as to realize the orderly arrangement of the stay wire. The steering wheel is located between the upper and lower layers of the housing. The steering wheel is connected with the bolt through the bearing, and the bolt is fixed on the shell. Two guide wheels are arranged above the measuring wheel. The winding direction is changed by the guide wheel, and the pull wire passes through the guide wheel and is wound to the measuring wheel. In addition, the laser positioner can be installed conveniently without the aid of the angle offset of the upper shell.

The steering wheel makes the measuring wheel and the winding wheel not in the same plane, so the whole mechanism is relatively small, and the wire rope directly drives the measuring wheel to rotate and measure.

The working principle of the invention is as follows: one end of the pull wire is fixed on the winding wheel, the other end is fixed on the pulling head, the pulling wire is pulled by external force, the pull wire passes through the pull hole, the measuring wheel is driven to rotate through the two guide wheels to realize the signal output, the pull wire passes through the steering wheel, changes the direction of the rope to another layer of the shell, and arranges the line on the winding wheel through the wire arranging wheel. Through the torsion provided by the spring, the winding wheel makes a certain tension act on the wire rope, and a cross laser locator is added to make the stay wire without angle offset.

The wire winding mechanism is designed separately from the measuring mechanism, and the winding state will not affect the measurement accuracy, so the measurement of large stroke can be achieved.

Among them, the measuring mechanism and winding mechanism described in the patent are distributed in single layer or multi-layer, which are protected by the patent. No matter whether the steering wheel and automatic wire arranging wheel are added in the mechanism, they are all protected by the patent.

The beneficial effect of the invention is that

(1) The wire rope directly drives the measuring wheel to rotate without passing through other conversion mechanism, which greatly improves the measurement accuracy.

(2) It is convenient to change the measurement resolution by changing the diameter of the measuring wheel. Since there is no limit on the measurement size, it can be made into a very small size to improve the resolution.

(3) The measurement mechanism is completely separated from the winding mechanism, which completely eliminates the axial error and winding swing angle error caused by the winding mechanism.

(4) The laser positioner is added to facilitate the installation of auxiliary stay wire without angle offset.

(5) The winding state of the winding mechanism will not affect the measurement. As long as the size of the winding mechanism is allowed, the measurement of large stroke can be achieved.
