Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of semi-trailer tractor engineering vehicles, specifically relating to an anti-collision buffer device for engineering vehicles. Background Technology
[0002] Construction vehicles are the backbone of a construction project. Their presence has greatly accelerated the progress of construction projects and significantly reduced manpower. Among them, semi-trailer tractors are a common type of construction vehicle, mainly used to tow commercial vehicles that pull semi-trailers. The trailer is towed by the tractor.
[0003] Currently, semi-trailer tractor-trailers lack collision buffer structures during use. When a rear-end collision occurs, the force of the collision cannot be buffered or dispersed, so almost all of the impact force is transmitted to the rear vehicle. This can result in minor damage such as deformation of the rear vehicle's front bumper, or even serious damage such as threatening the driver's cab, thus posing a safety hazard. Furthermore, the force of the collision can also cause deformation and damage to the tractor-trailer itself. Utility Model Content
[0004] (1) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a collision buffer device for engineering vehicles. This device aims to solve the problem that existing technologies do not have their own collision buffer structure, so when a rear-end collision occurs, the force generated by the collision cannot be buffered and dispersed. As a result, the collision force is almost entirely transmitted to the rear vehicle. This can lead to deformation of the rear vehicle's front bumper or even threaten the driver's cabin, posing a threat to personal safety. Furthermore, the force of the collision can also cause deformation and damage to the engineering vehicle.
[0006] (2) Technical solution
[0007] To solve the above-mentioned technical problems, this utility model provides an anti-collision buffer device for engineering vehicles, including a tractor body. A displacement mechanism is installed below the end of the tractor body. The displacement mechanism includes a main mounting guide, and an anti-collision buffer mechanism is jointly installed in the middle and front end of the main mounting guide. The anti-collision buffer mechanism includes an inner guide groove, which is opened in the middle of the main mounting guide. A first buffer component is installed in the middle of the inner guide groove, and a guide frame is movably guided in the middle of the inner guide groove. A front anti-collision frame is connected to the front end of the guide frame, and a second buffer component is installed in the front and rear ends of the front anti-collision frame and inside the inner guide groove.
[0008] Furthermore, the first buffer assembly includes a double-sided guide frame, which is disposed on both sides of the middle of the inner guide groove. Guide blocks are movable on both sides of the middle of the two double-sided guide frames, and the inner ends of the two pairs of guide blocks are connected to a first buffer spring. The bottom end of the guide frame is provided with two pairs of fixed blocks. Movable shafts are installed in the middle of the two pairs of fixed blocks and the corresponding guide blocks, and connecting frames are connected in the middle of the two movable shafts.
[0009] Furthermore, the guide block is elastically and movably connected by a first buffer spring and a double-sided guide frame.
[0010] Furthermore, the second buffer assembly includes a buffer pad, which is disposed at the front end of the front bumper. Second buffer springs are installed on both sides of the front end of the main mounting guide, damping spring shock absorbers are disposed at the end of the guide, and reflective strips are disposed at the front end of the buffer pad.
[0011] Furthermore, the two ends of the second buffer spring are respectively connected to the front bumper and the main mounting guide.
[0012] Furthermore, the displacement mechanism includes a lower frame, which is fixedly mounted below the end of the tractor body. A main mounting guide is movable in the middle of the lower frame, and a first limiting screw groove is provided on both sides of the main mounting guide. A second limiting screw groove is provided on both sides of the lower frame, and a limiting bolt is screwed between the second limiting screw groove and the corresponding first limiting screw groove.
[0013] Furthermore, the dimensions of the first limiting screw groove and the second limiting screw groove are matched.
[0014] (3) Beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] During the operation of the tractor body, the reflective strips on the front end of the outer buffer pad of the front anti-collision frame can provide a certain reflective warning effect to vehicles behind, reminding them to maintain a safe distance. Even if a vehicle behind accidentally collides with the tractor body, the second buffer springs connected to the main guide frame on both sides of the end of the front anti-collision frame can provide a certain degree of buffering. The guide frame at the end of the front anti-collision frame will move along the inner guide groove limit guide, thereby providing a certain degree of elastic shock absorption effect to the damping spring shock absorbers connected to the guide frame inside the inner guide groove. At the same time, the guide frame will press down on the two pairs of fixed blocks on both sides of the bottom. At this time, with the cooperation of the double guide frame, guide blocks, first buffer springs, and corresponding movable shafts and connecting frames, the buffering and shock absorption function of the tractor body and the vehicle behind can be effectively improved. Thus, in the unavoidable case, the impact force during the collision can be reduced, thereby improving safety to a certain extent.
[0017] When the engineering vehicle needs to move while towing the vehicle body, personnel can use the guiding movement between the lower frame and the main frame to pull out the frame until the front anti-collision frame at the front end of the main frame can exceed the appropriate length of the end of the vehicle body. Then, personnel can insert the limiting bolt into the second limiting screw groove on the side of the lower frame and the corresponding first limiting screw groove on the side of the main frame and lock it with threads. At this time, the front anti-collision frame, together with the corresponding buffer structure, can achieve the purpose of anti-collision buffering for the rear part of the vehicle body.

Figures 1 to 4 As shown, the device includes a tractor body 1. A displacement mechanism 2 is installed below the end of the tractor body 1. The displacement mechanism 2 includes a main mounting guide 22, and an anti-collision buffer mechanism 3 is jointly installed at the middle and front end of the main mounting guide 22. The displacement mechanism 2 includes a lower mounting frame 21, which is fixed below the end of the tractor body 1. The main mounting guide 22 is movable in the middle of the lower mounting frame 21. First limiting screw grooves 23 are opened on both sides of the main mounting guide 22, and second limiting screw grooves 24 are opened on both sides of the lower mounting frame 21. A limiting bolt 25 is screwed between the second limiting screw groove 24 and the corresponding first limiting screw groove 23. The dimensions of the first limiting screw groove 23 and the second limiting screw groove 24 are matched. When the engineering vehicle towing the vehicle body 1 needs to move, the personnel can use the guiding movement between the lower frame 21 and the main frame 22 to pull out the frame until the front anti-collision frame 34 set at the front end of the main frame 22 can exceed the appropriate length of the end of the vehicle body. Then, the personnel can insert the limiting bolt 25 into the second limiting screw groove 24 on the side of the lower frame 21 and the corresponding first limiting screw groove 23 on the side of the main frame 22 and lock it with threads. At this time, the front anti-collision frame 34, together with the corresponding buffer structure, can achieve the corresponding anti-collision buffer purpose for the rear part of the vehicle body.
[0026] The anti-collision buffer mechanism 3 includes an inner guide groove 31, which is located in the middle of the main mounting guide frame 22. A first buffer assembly 32 is installed in the middle of the inner guide groove 31.

Guide blocks 322 are movable on both sides of the middle of the two double-sided guide frames 321, and the inner ends of the two pairs of guide blocks 322 are connected to a first buffer spring 323. The bottom end of the guide frame 33 is provided with two pairs of fixing blocks 324, and a movable shaft 32 is installed in the middle of the two pairs of fixing blocks 324 and the corresponding guide blocks 322. 5. A connecting frame 326 is connected to the middle of the two movable shafts 325. The guide block 322 is elastically and movably connected by the first buffer spring 323 and the double-sided guide frame 321. The middle of the inner guide groove 31 is movably guided by the guide frame 33. The front end of the guide frame 33 is connected to the front bumper 34. The front and rear ends of the front bumper 34 and the interior of the inner guide groove 31 are equipped with a second buffer assembly 35. The second buffer assembly 35 includes a buffer pad 351, and the buffer pad 351 is set at the front end of the front bumper 34. The front ends of the main guide frame 22 are equipped with second buffer springs 352 on both sides. The end of the guide frame 33 is... The front end of the front bumper 351 is equipped with damping spring shock absorbers 353, and the front end of the buffer pad 351 is equipped with reflective strips 354. The two ends of the second buffer spring 352 are respectively connected to the front bumper 34 and the main mounting guide 22. During the driving of the tractor body 1, the reflective strips 354 on the front end of the buffer pad 351 on the outer side of the front bumper 34 can provide a certain reflective warning effect to the vehicles behind, reminding them to maintain a safe distance. Even if the vehicle behind accidentally hits it, the second buffer springs 352 connected to the main mounting guide 22 on both sides of the end of the front bumper 34 can provide a certain degree of cushioning. 33 will move along the limiting guide of the inner guide groove 31, so the damping spring shock absorber 353, which is set inside the inner guide groove 31 and connected to the guide frame 33, can play a certain elastic shock absorption effect. At the same time, the guide frame 33 will press down the two pairs of fixed blocks 324 on both sides of the bottom. At this time, with the cooperation of the double guide frame 321, guide block 322, first buffer spring 323, and corresponding movable shaft 325 and connecting frame 326, the buffering function of the rear of the traction vehicle body 1 and the vehicle can be effectively improved. Thus, in the unavoidable case, the impact force during the collision can be reduced, and a certain degree of safety can be improved.
[0027] Working principle: When the engineering vehicle towing vehicle 1 needs to move, personnel can use the guiding movement between the lower frame 21 and the main frame 22 to pull out the frame until the front bumper 34 at the front end of the main frame 22 can extend beyond the end of the vehicle body by an appropriate length. Then, personnel can insert the limiting bolt 25 into the second limiting screw groove 24 on the side of the lower frame 21 and the corresponding first limiting screw groove 23 on the side of the main frame 22 and lock it with threads. Subsequently, during the movement of the towing vehicle 1, the reflective strips 354 on the front end of the buffer pad 351 on the outer side of the front bumper 34 can provide a certain reflective warning effect to vehicles behind, reminding them to maintain a safe distance. Even if a vehicle behind accidentally collides with it, the reflective strips 354 on both sides of the end of the front bumper 34 will provide a certain reflective warning effect to vehicles behind, reminding them to maintain a safe distance. The second buffer spring 352 connected to the main mounting guide 22 can provide a certain buffer, and the end guide frame 33 of the front anti-collision frame 34 will move along the inner guide groove 31 for limiting and guiding. Thus, the damping spring shock absorber 353, which is set inside the inner guide groove 31 and connected to the guide frame 33, can provide a certain elastic shock absorption effect. At the same time, the guide frame 33 will press down on the two pairs of fixed blocks 324 on both sides of the bottom. At this time, with the cooperation of the double-sided guide frame 321, guide block 322, first buffer spring 323, and corresponding movable shaft 325 and connecting frame 326, the buffering function of the rear of the tractor body 1 and the vehicle can be effectively improved. Thus, in the unavoidable case, the impact force during the collision can be reduced, and a certain degree of safety can be improved.
