Description

Technical Field

[0001] The utility model relates to the technical field of wire-pulling displacement sensors, in particular to a wire-pulling direction adjusting device for a wire-pulling displacement sensor. Background Technique

[0002] The wire-pulling displacement sensor is also called a wire-pulling sensor, a wire-pulling electronic ruler, and a wire-pulling encoder. The wire-pulling displacement sensor is a delicate structure of a linear displacement sensor, which fully combines the advantages of an angle sensor and a linear displacement sensor, and becomes a sensor with small installation size, compact structure, large measurement stroke, and high precision. The stroke ranges from several hundred millimeters to dozens of meters.

[0003] Most of the existing technologies adopt a guiding mechanism for a wire-pulling displacement sensor disclosed in the publication number CN221006263U. The guiding mechanism for the wire-pulling displacement sensor in the utility model can adjust the angle of the cover plate as needed, thereby changing the pulling direction of the steel wire rope and increasing the flexibility of the pulling direction of the steel wire rope. However, it has the following defects in the actual use process:

[0004] Since the cover plate of the existing wire-pulling displacement sensor is directly rotatably installed on the fixed seat, only a horizontal wire-pulling direction adjustment can be performed based on the installation surface of the cover plate. When other horizontal wire-pulling direction adjustments are required for the existing wire-pulling displacement sensor, the existing guiding mechanism for the wire-pulling displacement sensor is unable to handle it, and the limitation is relatively large. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the wire-pulling direction cannot be adjusted on other horizontal planes in the existing technology, and a wire-pulling direction adjusting device for a wire-pulling displacement sensor is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A wire-pulling direction adjusting device for a wire-pulling displacement sensor includes a wire-pulling displacement sensor main body, a cover plate and a rotating wheel. A universal joint fixedly connected to the cover plate is movably embedded on the wire-pulling displacement sensor main body. An installation disk is fixedly installed on the wire-pulling displacement sensor main body, and a rotating disk is rotatably installed on the installation disk;

[0008] Four groups of first connection blocks and second connection blocks are respectively installed on the cover plate and the rotating disk by pins;

[0009] A guiding component is arranged between two of the first connection blocks and the second connection blocks;

[0010] A driving component is arranged between two of the first connection blocks and the second connection blocks.

[0011] Preferably, the first connection block is arranged at the corner positions on both sides of the cover plate, and the first connection block and the second connection block are arranged corresponding to each other vertically.

[0012] Preferably, the guiding assembly includes a movable rod fixedly connected to the first connection block, and the second connection block is fixedly connected with a sleeve slidably sleeved on the movable rod.

[0013] Preferably, a limiting plate slidably connected to the inner wall of the sleeve is fixedly connected to the lower end of the movable rod. The sleeve is a hollow cylindrical structure, and a guiding through hole for slidably sleeving the movable rod is opened at the upper end of the sleeve.

[0014] Preferably, the driving assembly includes a mounting frame fixedly connected to the second connection block. A lead screw is rotatably mounted on the mounting frame, and a moving slider is mounted on the lead screw in a matching manner. A connecting rod is fixedly connected between the first connection block and the moving slider.

[0015] Preferably, the mounting frame is of a gantry structure, and a driving disk is fixedly sleeved at one end of the lead screw close to the second connection block.

[0016] Compared with the prior art, the present utility model has the following advantages:

[0017] In the present utility model, the cover plate is movably mounted on the body of the wire-pulling displacement sensor through a universal joint, so that the cover plate can perform multi-dimensional position movement. Two groups of guiding assemblies and two groups of driving assemblies are used to support and limit the cover plate, so that the cover plate will not displace without external force. The driving assembly drives a linear movement in the vertical direction on one side of the cover plate, so that the cover plate performs an angular adjustment in the vertical direction. By using the rotational connection between the rotating disk and the mounting disk, an operator can directly rotate the rotating disk, thereby realizing the angular adjustment of the cover plate in the horizontal direction. The multi-dimensional direction adjustment of the rotating wheel driven by the cover plate helps to improve the flexibility when adjusting the wire-pulling direction of the wire-pulling displacement sensor.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Refer to Figures 1 - 4 , a pull wire direction adjusting device for a pull wire displacement sensor, including a pull wire displacement sensor body 1, a cover plate 2 and a rotating wheel 3. The rotating wheel 3 is used to set the steel wire rope. A universal joint 4 fixedly connected to the cover plate 2 is movably embedded on the pull wire displacement sensor body 1. Through the setting of the universal joint 4, the cover plate 2 can perform multi-dimensional movement when stressed.

[0028] A mounting plate 5 is fixedly installed on the pull wire displacement sensor body 1. A rotating disk 6 is rotatably installed on the mounting plate 5. The mounting plate 5 and the rotating disk 6 are rotatably connected through a damping bearing, so that the rotating disk 6 will not rotate without external force. Four groups of first connecting blocks 7 and second connecting blocks 8 are respectively pin-installed on the cover plate 2 and the rotating disk 6. The first connecting blocks 7 are arranged at the two side corner positions of the cover plate 2, and the first connecting blocks 7 and the second connecting blocks 8 are arranged corresponding to each other up and down;

[0029] Based on the setting of the first connecting block 7 and the second connecting block 8, in order to connect the cover plate 2 and the rotating disk 6, a guide assembly 9 is arranged between two of the first connecting blocks 7 and the second connecting blocks 8, so that when the rotating disk 6 rotates, the cover plate 2 can be synchronously driven to rotate through the guide assembly 9, thereby realizing the angle adjustment of the cover plate 2 in the horizontal direction;

[0030] A further implementation method is that the guiding component 9 includes a movable rod 901 fixedly connected to the first connecting block 7. The second connecting block 8 is fixedly connected with a sleeve 902 slidably sleeved on the movable rod 901. A limiting plate fixedly connected to the lower end of the movable rod 901 is slidably connected to the inner wall of the sleeve 902. The sleeve 902 is a hollow cylindrical structure. A guiding through hole for slidably sleeving the movable rod 901 is provided at the upper end of the sleeve 902. The movable rod 901 can be guided and limited through the guiding through hole, thereby providing a moving space for the vertical movement of the movable rod 901. And the diameter of the limiting plate is larger than the diameter of the guiding through hole. Therefore, the movable rod 901 will not be separated from the sleeve 902 when being stressed.

[0031] Based on the settings of the first connecting block 7 and the second connecting block 8, in order to adjust the angle of the cover plate 2 in the vertical direction, a driving component 10 is provided between two groups of the first connecting block 7 and the second connecting block 8.

[0032] A further implementation method is that the driving component 10 includes a mounting frame 1001 fixedly connected to the second connecting block 8. The mounting frame 1001 is of a gantry structure. A lead screw 1002 is rotatably mounted on the mounting frame 1001. The lead screw 1002 is rotatably connected to the mounting frame 1001 through a damping bearing, so that the lead screw 1002 will not rotate without external force. A driving disc is fixedly sleeved at one end of the lead screw 1002 close to the second connecting block 8.

[0033] A moving slider 1003 is installed on the lead screw 1002 in a matching manner. A connecting rod 1004 is fixedly connected between the first connecting block 7 and the moving slider 1003. The lead screw 1002 drives the connecting rod 1004 to perform a linear motion through the moving slider 1003. The connecting rod 1004 drives the cover plate 2 to perform an angle adjustment in the vertical direction through the second connecting block 8.

[0034] The functional principle of the present utility model can be described through the following operation methods:

[0035] When it is necessary to adjust the pulling wire direction of the pulling wire displacement sensor, rotate the rotating disc 6. The rotating disc 6 drives the cover plate 2 to rotate through the guiding component 9 and the driving component 10. The cover plate 2 drives the universal joint 4 to rotate, thereby realizing the angle adjustment in the horizontal direction.

[0036] Rotate the lead screw 1002. The lead screw 1002 drives the moving slider 1003 to perform a linear motion. The moving slider 1003 drives the connecting rod 1004 to perform a linear motion. The connecting rod 1004 drives the cover plate 2 to perform an angle adjustment in the vertical direction through the first connecting block 7, thereby realizing the multi-dimensional adjustment of the pulling wire direction of the pulling wire displacement sensor.

[0037] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
