DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-5 The hydraulic cylinder body impact protection device in the embodiment includes the protection box body 1, the hydraulic cylinder body 2 is fixedly installed inside the protection box body 1, the noise reduction baffle 3 is arranged outside the hydraulic cylinder body 2, the connecting assembly 5 is arranged inside the protection box body 1, the buffer box 6 is fixedly installed on the left and right sides of the protection box body 1, and the adjustable buffer assembly 7 is arranged inside the buffer box 6.

[0024] The adjustable buffer assembly 7 includes the damping plate 701, the damping plate 701 is slidingly installed inside the buffer box 6, a plurality of damping rods 702 are fixedly installed on the side of the damping plate 701 close to the inside of the buffer box 6, the moving plate 703 is slidingly arranged on the surface of the damping rod 702, the damping spring 704 is installed on the surface of the damping rod 702, the worm 705 is rotatably installed inside the buffer box 6, the worm wheel 706 is engaged with the top of the worm 705, the rotating rod 707 is fixedly installed at the center of the worm wheel 706, the screw rod 708 is fixedly installed at the left end of the rotating rod 707, and the screw cylinder 709 is threadedly installed on the surface of the screw rod 708.

[0025] As Figure 5 shown, when the noise reduction baffle 3 needs to be installed or disassembled, the fastening bolt can be disassembled with a tool, so that the maintenance door 4 is disassembled, and the noise reduction baffle 3 in the protection box body 1 is replaced.

[0026] AsFigure 1 and Figure 2 As shown, by setting up a connecting component 5, which includes a connecting box 501, a moving plate 502, a push rod 503, a triangular rod 504, a return spring 505, a moving block 506, and an insert block 507, the insert block 507 is adapted to the slot. When it is necessary to remove the noise reduction and sound insulation panel 3, the push rod 503 is pressed upward. The push rod 503 drives the triangular rod 504 to slide into the triangular groove of the moving block 506 through the movement of the moving plate 502. During the sliding process, the moving block 506 will move towards the return spring 505, thereby causing the insert block 507 to disengage from the slot inside the noise reduction and sound insulation panel 3, releasing the restriction on the noise reduction and sound insulation panel 3. When it is necessary to install, the spring force of the return spring 505 can be used to drive the insert block 507 into the slot to fix the noise reduction and sound insulation panel 3.

[0027] like Figure 1 As shown, by setting the handle and the door body, when it is necessary to adjust the extension and retraction stroke of the shock-absorbing spring 704, the staff only needs to open the door body, and then turn the worm gear 705 through the handle to carry out the subsequent operation.

[0028] It should be noted that the inner cavity of the noise reduction and sound insulation panel 3 is filled with polyethylene particles. The porous structure of the polyethylene particles can absorb sound waves, reduce sound reflection and propagation, thereby reducing noise.

[0029] When implementing this procedure, please follow these steps:

[0030] 1) First, use existing technology to predict whether the hydraulic cylinder 2 will be under high or low load after startup;

[0031] 2) Then, if, after prediction, the hydraulic cylinder 2 is under high load after operation, it will be subjected to greater pressure if it is subjected to an accidental impact. Therefore, it is necessary to increase the damping force of the damping spring 704. At this time, it is necessary to extend the extension stroke of the damping spring 704. Then, turn the handle.

[0032] 3) The handle drives the worm 705 to rotate, and the worm 705 drives the rotating rod 707 to rotate through meshing with the worm wheel 706;

[0033] 4) When the rotating rod 707 rotates, it drives the screw 708 to rotate. The screw 708 drives the screw 709 to move away from the damping block through the threaded connection with the screw barrel 709. The screw barrel 709 drives the moving plate 703 to move away from the damping block. During the sliding process, the moving plate 703 will drive the damping spring 704 to stretch, thereby improving its damping effect.

[0034] 5) Finally if the hydraulic cylinder 2 is in a low load situation, and if it is subjected to an accidental impact, the pressure it receives is relatively small, then the handle can be reversed to reduce the extension stroke of the shock absorbing spring 704.

[0035] To sum up, the hydraulic cylinder body impact protection device, by setting the connecting structure, through the cooperation of the connecting box 501 and the movement plate 502, the noise reduction sound insulation board 3 can be replaced in time, so as to ensure the sound insulation effect of the protection box 1 on the noise generated by the operation of the hydraulic cylinder 2, thereby reducing noise pollution and avoiding the influence on the operation of other equipment.

[0036] Moreover, the hydraulic cylinder body impact protection device, by setting the adjustable buffer assembly 7, through the cooperation of the shock absorbing plate 701 and the damping rod 702, not only effectively absorbs the external impact energy that the hydraulic oil cylinder may encounter during operation, but also adjusts its damping characteristics according to different working conditions and environmental changes, thereby keeping the device at the best shock absorbing effect.
