Description

Technical Field

[0001] This utility model relates to the field of mining vehicle technology, specifically, it is a mounting bracket for a lifting indicator switch of a mining vehicle's cargo box. Background Technology

[0002] During the application of mining trucks in mines, there have been instances where drivers forgot to lower the cargo box, leading to accidents such as encountering power lines, pipelines, or culverts while driving. Adding indicator lights or audible warnings to the cab helps drivers determine whether the cargo box has lowered. The method of fixing the indicator switch has become a focal point for various manufacturers. Existing technologies fall into two categories: one is installed inside the frame; the other is installed on the outside of the main beam. Installing it inside the frame provides dust protection, but it is difficult to operate during actual assembly. Adjusting it at the bottom of the cargo box poses safety hazards, endangering assembly and after-sales personnel. Current technology for installing it on the outside uses an elongated hole for vertical adjustment, but due to frequent pressure during use, the switch may loosen or even fall off over time.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Combined with appendix Figure 1-5 As shown, a mounting bracket for a lifting indicator switch of a mining truck's main compartment includes: a fixed bending plate 1, a fixed adjusting nut 2, an adjusting component 3, a switch fixing nut 5, a switch fixing bracket 6, and fixing bolts 7. The fixed bending plate 1 is L-shaped, and a waist-shaped hole in the front-to-back direction (Y-direction) is formed at the bottom so that one end of the adjusting component 3 passes through the waist-shaped hole from bottom to top and connects with the fixed adjusting nut 2. The waist-shaped hole is used to compensate for manufacturing and assembly errors to ensure assembly accuracy and facilitate adjustment of the installation position of the adjusting component 3 and the fixed adjusting nut 2. The side of the fixed bending plate 1 is fixed to the main longitudinal beam of the main compartment. In this embodiment, the side of the fixed bending plate 1 is welded to the main longitudinal beam of the main compartment. The other end of the adjusting component 3 is used to cooperate with the telescopic end of the lifting indicator switch 4 to realize the positive and negative terminals being connected and disconnected; the lifting indicator switch 4 has at least two mounting bolts on its side, and the at least two mounting bolts are arranged vertically; the switch fixing bracket 6 is inverted "L" shape, and a mounting hole is formed on the side near the lifting indicator switch 4 to cooperate with at least two mounting bolts of the lifting indicator switch 4, and the at least two mounting bolts pass through the mounting hole to cooperate with the switch fixing nut 5; the side of the switch fixing bracket 6 away from the lifting indicator switch 4 has at least two bracket mounting holes in the vertical direction (Z direction), which are used to cooperate with the fixing bolts 7 to install the switch fixing bracket 6 on the longitudinal beam of the vehicle frame.

[0026] Preferably, the bracket mounting hole is a horizontal, i.e., an X-shaped hole, to compensate for manufacturing and assembly errors and ensure assembly accuracy.

[0027] Furthermore, this mounting bracket is installed on the front side of the mudguard, effectively reducing the damage from dust, water, and mud.
