Description

Technical Field

[0001] This utility model belongs to the field of automatic measurement technology, and in particular relates to a device that can automatically and accurately measure the telescopic length of a winch cable. Background Technology

[0002] Winch cables are typically wound in multiple layers on a drum, which is quite wide. Therefore, during winch operation, the cable extends and undergoes significant displacement in both the horizontal and vertical directions. The cable length measuring equipment must accommodate this movement in both directions to accurately measure the extended cable length.

[0003] Current steel cable length measuring equipment is bulky, takes up a lot of space, is cumbersome to install, and the spring device used cannot adjust the clamping force, and often slips and wears out.

[0004] Therefore, how to automatically and accurately measure the extension length of winch cables is a technical problem that the industry urgently needs to solve. Utility Model Content

[0005] One of the main objectives of this invention is to provide a steel cable length measuring device that can automatically and accurately measure the extension and retraction length of a winch steel cable.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] As in one aspect of this utility model, a steel cable length measuring device is provided for measuring the extension length of a winch cable in the direction of traction of a cargo, the cargo moving along a set direction. The device includes a frame, a transverse rail, and a guide frame. The frame is fixedly disposed between the winch and the cargo. The transverse rail is mounted on the frame, and its extension direction is perpendicular to the direction of movement of the cargo. The guide frame is movably mounted on the transverse rail and includes two opposing rollers and an elastic clamping mechanism abutting against the two rollers. The roller axes are vertically arranged, and an encoder is driven to connect any one of the rollers. The elastic clamping mechanism clamps the two rollers together, and the steel cable passes through the gap between the two rollers.

[0008] In one embodiment of this utility model, the cargo slides along the ground track and is connected to the steel cable for traction.

[0009] As in one embodiment of the present invention, the frame includes two guide rollers, which correspond to the lower parts of the inlet and outlet of the two rollers, respectively.

[0010] In one embodiment of the present invention, the frame includes a base, a column and an upper support frame. The upper support frame is mounted on the base via the column. The base is fixedly installed. The transverse track is mounted on the upper support frame and the guide roller is mounted on the base.

[0011] As in one embodiment of the present invention, the guide frame includes two fixed frames, the two rollers are mounted on the two fixed frames in a one-to-one correspondence, and the transverse track is sleeved on the upper part of the two fixed frames.

[0012] In one embodiment of this utility model, there are two transverse tracks, and the two transverse tracks are respectively sleeved on both sides of the two fixed frames.

[0013] In one embodiment of the present invention, a connecting rod is provided between the two fixed frames, and a spring is sleeved on the connecting rod, with the spring clamped between the end of the connecting rod and the fixed frame.

[0044] The steel cable length measuring device of this utility model includes a frame 1, a transverse track 2, and a guide frame 3. The frame 1 is fixedly disposed between the winch 4 and the cargo 5. The transverse track 2 is mounted on the frame 1, and its extension direction is perpendicular to the movement direction of the cargo 5. The guide frame 3 is movably mounted on the transverse track 2 and includes two opposing rollers 31 and an elastic clamping mechanism abutting against the two rollers 31. The axes of the rollers 31 are vertically arranged, and each roller 31 is connected to an encoder (not shown in the figure). The elastic clamping mechanism clamps the two rollers 31 together, and the steel cable 6 passes through the gap between the two rollers 31. The elastic clamping mechanism clamps the steel cable 6 between the two rollers 31 using elastic force, ensuring that the steel cable 6 reliably drives the rollers 31 to rotate during extension and retraction, preventing loss of rotation and improving measurement accuracy.

[0045] In one embodiment of this utility model, the cargo 5 slides onto the ground track and is connected to the steel cable 6 for traction.

[0046] As in one embodiment of the present invention, the frame 1 includes two guide rollers 11, which correspond to the lower parts of the inlet and outlet of the two rollers 31, respectively.

[0047] In one embodiment of this utility model, the frame 1 includes a base 12, a column 13, and an upper support frame 14. The upper support frame 14 is mounted on the base 12 via the column 13, the base 12 is fixedly installed, the transverse track 2 is mounted on the upper support frame 14, and the guide roller 11 is mounted on the base.

[0048] As in one embodiment of the present invention, the guide frame 3 includes two fixed frames 32, and the two rollers 31 are installed on the two fixed frames 32 in a one-to-one correspondence. The upper part of the two fixed frames 32 is sleeved with the transverse track 2.

[0049] In one embodiment of this utility model, there are two transverse tracks 2, and the two transverse tracks 2 are respectively sleeved on both sides of the two fixed frames 32.

[0050] In one embodiment of the present invention, a connecting rod 33 is provided between the two fixed frames 32, and a spring 34 is sleeved on the connecting rod 33. The spring 34 is clamped between the end of the connecting rod 33 and the fixed frame 32.

[0051] In one embodiment of the present invention, a baffle 35 is connected to the end of the connecting rod 33, and the spring 34 is clamped between the baffle 35 and the fixing frame 32.

[0052] In one embodiment of this utility model, there are four connecting rods 33, which are respectively connected to the four corners of the fixed frame 32.

[0053] In one embodiment of this utility model, a baffle 35 is connected between the two upper connecting rods 33, and a baffle 35 is also connected between the two lower connecting rods 33. The baffle 35, connecting rods 33, spring 34, and fixing frame 32 together constitute an elastic clamping mechanism, which abuts against and supports the two rollers 31, and drives the two rollers 31 to move on the transverse guide rail 2.

[0054] As can be seen from the above technical solution, the advantages and positive effects of the steel cable length measuring device of this utility model are as follows:

[0055] In this invention, the steel cable 6 passes through the gap between the two rollers 31. When the steel cable 6 extends or retracts, it drives the rollers 31 to rotate and drives the encoder to count.
