[0029] Embodiment 2

[0030] Based on Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working methods, as Figures 1 to 5 shown, and the details are described below:

[0031] As a preferred implementation manner, a second lead screw 15 is installed in the adjusting rail 3, and a second nut 16 whose shape matches the internal shape of the adjusting rail 3 is sleeved on the second lead screw 15. The top of the second nut 16 is connected to the first guide wheel 17 by bolts, and an adjusting handle 1501 is installed on the adjusting rail 3 on one side of the second nut 16; further, rotating the adjusting handle 1501 can drive the second lead screw 15 to rotate, so that the second nut 16 moves left and right in the adjusting rail 3, adjusting the position of the first guide wheel 17 to achieve the adjustment of the wire outlet position.

[0033] As a preferred implementation manner, the protection assembly 7 includes a mounting sleeve 701, a ground fixing member 702, and a diagonal brace 703. The mounting sleeve 701 is welded to the gantry 6. Diagonal braces 703 are hinged at both ends of the mounting sleeve 701, and ground fixing members 702 are hinged at the bottoms of the diagonal braces 703. The ground fixing members 702 are fixed to the detection platform 1 by bolts; further, the protection assembly 7 can reinforce the gantry 6, making it not easy to topple, and the safety of the detection is higher.

[0034] As a preferred implementation manner, an anti - detachment disk 801 with a diameter larger than the outer diameter of the pull rod 8 is welded to the bottom of the pull rod 8, and the pull rod 8 is thread - connected to the connecting member 24; further, the thread - connection design makes the disassembly and assembly of the connecting member 24 and the pull rod 8 more convenient, and it is more convenient to increase or decrease the detection weight 25, and the operation is very convenient.

[0035] As a preferred embodiment, the weight assembly 9 includes a number of test weights 25 with different specifications. Limit grooves 2501 that match the shape of the limit rods 23 are formed on both sides of the test weights 25. Through holes 2503 with an inner diameter that matches the outer diameter of the pull rod 8 are formed at the central positions of the test weights 25, and anti - detachment holes 2502 that match the outer diameter of the anti - detachment disc 801 are provided at the bottoms of the through holes 2503. Further, during testing, the test weights 25 can be directly sleeved on the pull rod 8 and put into use. It is very convenient to increase or decrease them. In addition, the limit rods 23 are exactly located in the limit grooves 2501 on both sides of the test weights 25, which can limit the test weights 25 and prevent them from shaking back and forth during lifting tests, making the testing safer.

[0036] As a preferred embodiment, lifting grooves 1201 are formed at both ends inside the adjusting seat 12. First lead screws 1202 are installed in the lifting grooves 1201. First nuts 11 that are adapted to the first lead screws 1202 are sleeved on the first lead screws 1202. Casters 10 are installed on the sides of the first nuts 11 away from the winch mounting seat 2 by bolts. Chain wheel mechanisms 13 are installed on the tops of the adjusting seats 12, and the drive wheels of the chain wheel mechanisms 13 are connected to the first lead screws 1202 below them. Rotating handles 14 are installed at one ends of the tops of the adjusting seats 12, and the bottom output ends of the rotating handles 14 are connected to one of the drive wheels of the chain wheel mechanisms 13. Further, rotating the rotating handle 14 can drive the two first lead screws 1202 to rotate synchronously through the chain wheel mechanism 13, enabling the first nuts 11 to move up and down in the lifting grooves 1201 to adjust the height of the casters 10. When the winch mounting seat 2 needs to be transferred, the casters 10 move down to contact the ground, facilitating the transfer. When testing is required, the casters 10 are lifted up so that the winch mounting seat 2 contacts the ground, making the placement more stable.

[0037] The working process of the present utility model is as follows:

[0038] During use, place the winch to be tested on the winch mounting base 2. Rotating the rotating handle 14 can drive the two first lead screws 1202 to rotate synchronously through the sprocket mechanism 13, that is, make the first nut 11 rise and fall in the lifting groove 1201 to adjust the height of the casters 10. When it is necessary to transfer the winch mounting base 2, the casters 10 move down to contact the ground, which is convenient for transfer. When testing is required, the casters 10 are lifted to make the winch mounting base 2 contact the ground. During testing, rotating the adjusting handle 1501 can drive the second lead screw 15 to rotate, so that the second nut 16 moves left and right in the adjusting rail 3 to adjust the position of the first guide wheel 17, realizing the adjustment of the wire outlet position. Directly put an appropriate amount of test weights 25 on the pull rod 8, and then thread the connecting piece 24 to the pull rod 8. The winch to be tested works to take in the wire, pull the grinding rope 5 to make the weight assembly 9 move up. At this time, the spring pull column 18 can achieve the buffering of the tension, and the force value of the tension gauge 4 is the actual output of the motorized winch to be tested during the test.

[0039] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
