AI Technical Summary
When the cab bumpers of existing heavy equipment transport vehicles are connected by bolts or castings, abnormal noises and shaking are likely to occur, affecting safety, and the production cycle is relatively long.
The anti-collision bumper connection structure is manufactured using machined parts. It uses connecting screws, thrust nuts, wing nuts and locking devices. The combination of screws and traction seats ensures the fixed connection of the bumper and prevents shaking. Stainless steel wing nuts, flat washers and spring washers are used for fastening.
This effectively avoids abnormal noises and shaking from the bumper, improves safety, and greatly shortens the production cycle.

Abstract
Description
Technical Field
[0001] This utility model relates to a connection structure, specifically a fixed connection structure for a crash barrier of a heavy equipment transport vehicle. Background Technology
[0002] Currently, the bumpers of transport vehicle cabs are basically connected by bolts or castings. This method of connection can cause abnormal noises and shaking, affecting the safety of drivers and passengers. In addition, the development cycle of castings is long. Utility Model Content
[0003] The purpose of this utility model is to design a fixed connection structure for a crash barrier of a heavy equipment transport vehicle. It adopts the manufacturing method of machined parts and uses screws, thrust nuts and wing nuts to fix the crash barrier, avoiding abnormal noise, shaking and other problems, and has the characteristics of short production cycle.
[0004] This utility model is achieved through the following technical solution:
[0005] A fixed connection structure for a crash bumper of a heavy equipment transport vehicle includes a connecting screw 1, a thrust nut 2, a traction ring 3, a positioning pin 4, a traction seat 5, and a locking device 6. The connecting screw 1, which is used to connect with the front crossbeam, is fixed on the traction seat 5. The thrust nut 2 cooperates with it. The locking device 6, which is used to fix the bumper, is installed on the upper part of the traction seat 5. The two ends of the traction ring 3 are respectively installed on the side and bottom of the traction seat 5. The positioning pin 4 is installed on the side of the traction seat 5. Compared with the traction ring 3, the positioning pin 4 is located closer to the front crossbeam.
[0006] The locking device 6 is a wing nut.
[0007] The wing nut is installed in conjunction with a flat washer and a spring washer.
[0008] This invention avoids abnormal noises and shaking in the fixed connection structure when a bumper is added to a transport vehicle, and it is easy to assemble and disassemble with a short manufacturing cycle. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the structure of this utility model;
[0010] Figure 2 This is a diagram showing the connection between this utility model and the first crossbeam;
[0011] Figure 3 This is a diagram showing the connection between this utility model and the anti-collision bumper;
[0012] Figure 4 yes Figure 3 A partial view. Detailed Implementation
[0013] The anti-collision bumper fixing connection method described in this utility model mainly consists of a connecting screw 1, a thrust nut 2, a traction ring 3, a positioning pin 4, a traction seat 5, and a locking device 6, etc. (See attached diagram) Figure 1-4 .
[0014] During assembly, first screw the connecting bolt 1 into the first crossbeam mounting base, then tighten the mounting base in the reverse direction using the thrust nut 2. Figure 2 The bumper is fixed to the mounting hole of the towing seat 5 and the bumper is pressed together by the locking device 6, see Figure 3 Complete the fixing of the bumper.
[0015] The key technical point of this utility model is:
[0016] 1. Install a thrust nut at the connecting screw to ensure a secure threaded connection that does not loosen.
[0017] 2. A positioning pin is added to the towing seat to prevent the towing ring from swaying back and forth and hitting the vehicle body during driving.
[0018] 3. A locking device is installed above the towing seat, using standard stainless steel wing nuts, flat washers, and spring washers to secure the bumper tightly, ensuring that the bumper does not wobble. Disassembly is easy; simply loosen the wing nuts and rotate them 90 degrees clockwise.
