Description

Technical Field

[0001] This utility model relates to the field of winch traction drive technology, specifically a rectangular frame adapted to and connected to a winch. Background Technology

[0002] In the existing technology, for vehicle frames or transport devices that lack a built-in drive unit, a winch is usually used for traction drive, and the winch moves the vehicle frame by winding the traction rope.

[0003] However, during the traction process, for frame equipment that requires precision construction, it is necessary to ensure the stability of the traction. Therefore, the traction direction must be parallel to the direction of frame movement. For example, when the trolley is placed on a slope, the traction height of the winch must correspond to the connection height of the frame. At this time, it is necessary to ensure that the traction rope is parallel to the slope. When the traction rope shifts upward, it will apply an upward driving force to the frame, which can easily cause the frame to lift up. When the traction rope shifts downward, it will cause the end of the frame to be pressed down and shifted, which cannot guarantee the smooth traction drive of the frame. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution:

[0023] Example 1: A rectangular frame adapted to connect with a winch. The rectangular frame 1 is set on an inclined slope. A connecting component for connecting with the winch is set on one side of the rectangular frame 1. The connecting component includes a connecting frame 3 and a side frame 2. A lifting adjustment rod 16 for driving the height adjustment of the connecting frame 3 is set on the side frame 2. One end of the lifting adjustment rod 16 is fixed to the upper end of the connecting frame 3, and the other end of the lifting adjustment rod 16 is fixed to the upper end of the side frame 2.

[0024] By setting up the lifting adjustment rod 16, the height of the connecting frame 3 on the side frame 2 can be adjusted.

[0025] The end of the connecting frame 3 is provided with a vertical groove 11. The middle of the vertical groove 11 is provided with an enlarged hole groove 12 with an inner diameter greater than the width of the vertical groove 11. The middle of the enlarged hole groove 12 is provided with a through hole block 13. Semi-arc blocks 14 that fit the arc inner wall of the enlarged hole groove 12 are elastically installed on both sides of the through hole block 13. The width of the pair of semi-arc blocks 14 after pressing against the through hole block 13 is less than the width of the vertical groove 11.

[0026] By setting a pair of elastically installed semi-circular blocks 14, when the traction rope shifts upward or downward, the through-hole block 13 is driven to shift and slide up and down under the action of traction force. At this time, the pair of semi-circular blocks 14 are elastically pressed and slid into the vertical groove 11. The direction of the traction rope shift is determined according to its position, and the position is adjusted by using the lifting adjustment rod 16. When the traction direction is parallel to the movement direction, the through-hole block 13 is subjected to the tension of the vertical groove 11. At this time, the semi-circular blocks 14 are exactly located in the position of the enlarged groove 12. Under the action of the reset elastic force, the semi-circular blocks 14 expand outward and fit against the inner wall of the enlarged groove 12.

[0027] Example 2: Based on Example 1, one side of the side frame 2 is fixed to one end of the rectangular frame 1. The side frame 2 is provided with a pair of vertically extending slide grooves 4. The side of the connecting frame 3 near the side frame 2 is provided with a crossbeam 5 that fits against the side wall of the side frame 2. The crossbeam 5 is provided with a slider that slides in cooperation with the slide grooves 4. The through hole block 13 is provided with a through hole in the middle. A second pull rope 9 connected to the inner side of the connecting frame 3 is provided through the through hole. The end of the second pull rope 9 located on the outer side of the connecting frame 3 is provided with a hanging ring 8 with an outer diameter larger than the inner diameter of the through hole. The hanging ring 8 is connected to the traction rope of the winch.

[0028] By setting the second pull rope 9 and the hanging ring 8 together, it is easy to connect with the traction rope of the winch, and at the same time avoids the temporary wiring installation of the second pull rope 9. By setting the slide groove 4 and the crossbeam 5 together, the smooth lifting and lowering adjustment of the connecting frame 3 is guaranteed.

[0029] A pull block 6 is slidably arranged in the inner cavity of the connecting frame 3. One end of the second pull rope 9 is connected to the pull block 6. Both ends of the crossbeam 5 are connected to the pull block 6 through the first pull rope 7. A sleeve 10 is arranged on the crossbeam 5 directly opposite the pull block 6. A plug rod is slidably inserted into the sleeve 10 on the pull block 6.

[0030] By setting the sleeve 10 and the insertion rod together, the limiting traction sliding of the pull block 6 is realized. By setting the first pull rope 7 symmetrically distributed, the uniform traction on both sides of the rectangular frame 1 is realized, avoiding deviation.

[0031] Example 3: Based on Example 2, the semi-circular block 14 is prone to getting stuck at the connection position between the vertical groove 11 and the enlarged hole groove 12. Therefore, the connection is designed with rounded corners, and elastic elements 15 connected to the inner arc of the semi-circular block 14 are provided on both sides of the through hole block 13. The elastic elements 15 are springs. Vertical plates that fit the inner wall of the vertical groove 11 are extended from both the upper and lower ends of the semi-circular block 14.

[0032] By setting the elastic element 15, the semi-circular block 14 can be installed elastically. By setting the vertical plate that fits the vertical groove 11, a smooth connection is formed, ensuring that it can accurately and smoothly enter the vertical groove 11 under the offset action of the traction force.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
