The first anti-loosening part is sleeved on the heads of two adjacent bolts, and another first anti-loosening part is sleeved on the heads of the other two adjacent bolts. The second anti-loosening part is sleeved on two adjacent nuts, and another second anti-loosening part is sleeved on the other two adjacent nuts. The two first anti-loosening parts sequentially penetrate the mounting plate, the support plate, and the second anti-loosening parts, and then a stop plate is inserted.
[0005] Furthermore, the mounting plate is in the shape of a square plate, the mounting plate is perpendicular to the ground, and four through holes are symmetrically arranged on the four corners of the mounting plate.
[0006] Furthermore, the support plate is provided with two strip holes in the vertical direction, the horizontal distance between the two strip holes is the distance between the two through holes in the horizontal direction, and the width of the strip hole is the same as the diameter of the through hole.
[0007] Furthermore, the bolts are passed through the through holes and the strip holes and then bolted with nuts, and the mounting plate is bolted to the support plate in an adjustable height through the bolts, nuts, through holes and the strip holes.
[0008] Furthermore, both ends of the first anti-loosening part and the second anti-loosening part are circular ring-shaped, the inner walls of both ends of the circular rings of the first anti-loosening part and the second anti-loosening part are toothed, an insertion rod is welded in the middle part of the first anti-loosening part, and an insertion hole is opened in the middle part of the second anti-loosening part, and the positions of the insertion rod and the insertion hole correspond to each other.
[0009] Furthermore, the two ends of the circular ring shape of the first anti-loosening member are respectively sleeved on the heads of two adjacent bolts in the vertical direction, and the toothed inner walls at both ends of the first anti-loosening member engage with the outer walls of the bolt heads.

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0022] like Figure 1-3 As shown, a height-adjustable and anti-loosening buffer device for an overhead crane comprises a buffer 1, two first anti-loosening members 2, and two second anti-loosening members 3. A mounting plate 4 is provided at the fixed end of the buffer 1. The mounting plate 4 is height-adjustably bolted to a support plate 5 by four bolts 6 and four nuts 7. The first anti-loosening member 2 is sleeved on the heads of two adjacent bolts 6, and another first anti-loosening member 2 is sleeved on the heads of the other two adjacent bolts 6. The second anti-loosening member 3 is sleeved on two adjacent nuts 7, and another second anti-loosening member 3 is sleeved on the other two adjacent nuts 7. The two first anti-loosening members 2 sequentially penetrate the mounting plate 4, the support plate 5, and the second anti-loosening member 3, and a stop plate 8 is inserted thereafter.
[0023] The mounting plate 4 is in the shape of a square plate, and the mounting plate 4 is perpendicular to the ground. Four through holes 9 are symmetrically arranged at the four corners of the mounting plate 4 .
[0024] The support plate 5 is provided with two strip holes 10 in the vertical direction. The horizontal distance between the two strip holes 10 is the distance between the two through holes 9 in the horizontal direction. The width of the strip hole 10 is the same as the diameter of the through hole 9 .
[0025] The bolts 6 pass through the through holes 9 and the strip holes 10 and are then bolted to the nuts 7 . The mounting plate 4 is bolted to the support plate 5 via the bolts 6 , the nuts 7 , the through holes 9 and the strip holes 10 in a height-adjustable manner.
[0026] Both ends of the first anti-loosening part 2 and the second anti-loosening part 3 are circular ring-shaped, and the inner walls of both ends of the circular rings of the first anti-loosening part 2 and the second anti-loosening part 3 are toothed. An insertion rod 11 is welded to the middle part of the first anti-loosening part 2, and an insertion hole 12 is opened in the middle part of the second anti-loosening part 3. The positions of the insertion rod 11 and the insertion hole 12 correspond to each other.
[0027] The two ends of the circular ring shape of the first anti-loosening member 2 are respectively sleeved on the heads of two adjacent bolts 6 in the vertical direction, and the toothed inner walls at both ends of the first anti-loosening member 2 bite the outer walls of the heads of the bolts 6. The two ends of the circular ring shape of the second anti-loosening member 3 are respectively sleeved on two adjacent nuts 7 in the vertical direction, and the toothed inner walls at both ends of the second anti-loosening member 3 bite the outer walls of the nuts 7.
[0028] A slot 13 is provided on the insertion rod 11, and two stop grooves 14 are provided on the stop plate 8. After the insertion rods 11 of the two first anti-loosening parts 2 pass through the strip holes 10 of the mounting plate 4 and the support plate 5 and the insertion hole 12 of the second anti-loosening part 3 in sequence, the two stop grooves 14 on the stop plate 8 are respectively inserted into the slots 13 of the two insertion rods 11.
[0029] The working principle of the utility model is:
[0030] When in use, weld the support plate 5 to the overhead crane, bolt the mounting plate 4 of the buffer 1 to the strip hole 10 of the support plate 5 through the bolts 6 and nuts 7, and pay attention to adjusting the height before tightening the bolts 6. At this time, sleeve the two ends of the two second anti-loosening parts 3 on the two nuts 7 in the vertical direction, penetrate the two first anti-loosening parts 2 with the rods 11 of the mounting plate 4, the strip hole 10, and the insertion hole 12, and sleeve the two ends of the first anti-loosening parts 2 on the heads of the two bolts 6 in the vertical direction. At this time, the slot 13 is located on the outside of the second anti-loosening part 3, and align the two stop grooves 14 of the stop plate 8 and insert them into the two slots 13.
[0031] The outer walls of the heads of the two bolts 6 bite the toothed inner walls at both ends of the first anti-loosening member 2. When the bolts 6 show signs of loosening, the heads of the two bolts 6 are relatively fixed, thus limiting the rotational loosening of the bolts 6, thereby preventing the bolts 6 from loosening. Similarly, the outer walls of the two nuts 7 bite the toothed inner walls at both ends of the second anti-loosening member 3. When the nuts 7 show signs of loosening, the heads of the two nuts 7 are relatively fixed, thus limiting the rotational loosening of the nuts 7, thereby preventing the nuts 7 from loosening. The insertion rod 11 of the first anti-loosening member 2 is inserted into the insertion hole 12 of the second anti-loosening member 3, and is limited by the stop plate 8, thereby fixing the first anti-loosening member 2 and the second anti-loosening member 3 to prevent them from falling off.
[0032] When the height needs to be adjusted again, pull out the stop plate 8 from the slot 13, and the first anti-loosening component 2 can be separated from the second anti-loosening component 3. After removing the first anti-loosening component 2 and the second anti-loosening component 3 from the bolts 6 and nuts 7 respectively, loosen the bolts 6 and nuts 7, and the height can be adjusted. After adjusting the height, tighten the bolts 6 and nuts 7, install the first anti-loosening component 2 and the second anti-loosening component 3, and then insert the stop plate 8 into the slot 13.
[0033] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.
