Description

Personnel vehicle chassis and personnel vehicle for going down into and out of the well Technical Field

[0001] This utility model relates to the field of personnel vehicle chassis technology, and in particular to personnel vehicle chassis and personnel vehicles used for going down into wells. Background Technology

[0002] During the construction and excavation of mines, it is often necessary to transport and transfer workers in the mine roadways using personnel transport vehicles.

[0003] For example, a patent entitled "Mining Personnel Transport Vehicle" (patent application number: CN201920844271.3) discloses a mining personnel transport vehicle. It features a protective frame on the outside of the vehicle body. In the event of a mine collapse, the protective frame provides excellent support and protection, preventing the collapsed rocks from crushing the vehicle body and effectively ensuring the safety of personnel inside. A water tank is also installed inside the vehicle. If personnel are trapped inside the vehicle during a mine accident, the water in the tank can provide them with the necessary hydration to prolong their survival time while awaiting rescue. However, the chassis lacks a protective structure for the front differential assembly. Since there are often loose ore blocks in the mine tunnels, if the driver does not react quickly enough, the suspension assembly could easily collide with these ore blocks, posing a potential damage risk.

[0004] Therefore, it is necessary to propose a personnel carrier chassis and a personnel carrier for going down into and out of the well to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a chassis for a personnel carrier and a personnel carrier for going down into the mine, so as to solve the problem that the chassis lacks a protective structure for the front differential assembly. Since there are many loose ore blocks in the mine roadways, if the driver does not control and avoid them in time during the operation of the personnel carrier, the suspension assembly is prone to hitting the ore blocks, which poses a potential risk of damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a personnel carrier chassis and a personnel carrier for going down into the well, including a frame assembly and a front differential assembly. The frame assembly includes a front crossbeam, a rear crossbeam, and two longitudinal beams. The longitudinal beams are fixedly connected between the front and rear crossbeams and are distributed in parallel. The front differential assembly is located between the front and rear crossbeams and is close to the front crossbeam. A crossbar is fixedly connected between the two longitudinal beams. The crossbar is located between the front differential assembly and the front crossbeam. A fixing plate is fixedly connected to the bottom of the crossbar. A square groove is formed through the fixing plate. A sliding column is slidably arranged inside the square groove. A sliding plate is fixedly connected to one end of the sliding column near the front differential assembly. An arc plate is fixedly connected to the bottom of the sliding plate, and the concave surface of the arc plate is close to the front differential assembly.

[0007] Preferably, a limiting plate is fixedly connected to the end of the sliding column away from the sliding plate, and a second spring is fitted on the outside of the sliding column. One end of the second spring is fixedly connected to the limiting plate, and the other end of the second spring is fixedly connected to the fixing plate.

[0008] Preferably, the lower surface of the crossbar is provided with a groove, and a slider is slidably disposed inside the groove, with the slide plate fixedly connected to the bottom of the slider.

[0009] Preferably, the slide groove is provided with a buffer assembly, which includes a damper and a first spring. One end of the damper is fixedly connected to the inner wall of the slide groove, and the other end of the damper is fixedly connected to the slider. The first spring is fitted on the outside of the damper, and one end of the first spring is fixedly connected to the inner wall of the slide groove, and the other end of the first spring is fixedly connected to the slider.

[0010] Preferably, a blade is fixedly connected to one side of the arc plate facing away from the front differential assembly.

[0011] This utility model also discloses a personnel carrier for going down into and out of the well, which uses the aforementioned personnel carrier chassis.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by setting up structures such as a sliding plate and an arc plate, allows the sliding plate and arc plate to be positioned at the front end of the front differential assembly during vehicle movement. If there are any fallen mineral blocks on the ground, the sliding plate and arc plate can protect the front differential assembly. The arc-shaped surface of the arc plate can press the mineral blocks downwards and break them, avoiding damage to the chassis. Furthermore, the arc plate and sliding plate move towards the front differential assembly through the cooperation of square grooves and sliding columns, with the arc plate covering the bottom of the front differential assembly, thereby achieving overall protection of the front differential assembly.

[0014] 2. When the arc plate and the sliding plate move towards the front differential assembly through the cooperation of the square groove and the sliding column, the second spring will be compressed by the limit plate. The second spring will relieve the force and buffer, improve the protection effect of the sliding plate and other structures, and avoid direct hard contact that could cause high-frequency vibration of people and vehicles.

[0015] 3. When the arc plate and the sliding plate move towards the front differential assembly through the cooperation of the square groove and the sliding column, they will compress the damper and the first spring, and the damper and the first spring will perform a second force relief and buffering.

[0016] 4. Add blades to improve the crushing effect of the arc plate on the ore block. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a vehicle chassis as shown in Figures 1 to 5, including a frame assembly and a front differential assembly 5. The frame assembly includes a front crossbeam 2, a rear crossbeam 3, and two longitudinal beams 1. The longitudinal beams 1 are fixedly connected between the front crossbeam 2 and the rear crossbeam 3, and the two longitudinal beams 1 are distributed in parallel. The front differential assembly 5 is located between the front crossbeam 2 and the rear crossbeam 3, and is close to the front crossbeam 2. In actual use, it also includes a suspension assembly, wheel hub assembly, and other structures that cooperate with the front differential assembly 5. The chassis structure and its working principle are common existing technologies and will not be described in detail here.

[0025] Considering the numerous loose ore blocks in the mine tunnels, if the driver fails to react quickly enough, the front differential assembly 5 and other structures could easily collide with these blocks, posing a potential damage hazard. Therefore, a crossbeam 4 is fixedly connected between the two longitudinal beams 1. The crossbeam 4 is located between the front differential assembly 5 and the front crossbeam 2. A fixing plate 10 is fixedly connected to the bottom of the crossbeam 4. A square groove 12 is formed through the fixing plate 10, and a sliding column 13 is slidably installed inside the square groove 12. A sliding plate 11 is fixedly connected to the end of the sliding column 13 closest to the front differential assembly 5. An arc plate 16 is fixedly connected to the bottom of the sliding plate 11, with its concave surface close to the front differential assembly 5. The arc plate 16 serves to guide and expand the protection range.

[0026] Specifically, during the movement of the vehicle, the sliding plate 11 and the arc plate 16 are at the front end of the front differential assembly 5 in the direction of movement. If there are any fallen mineral blocks on the ground, the sliding plate 11 and the arc plate 16 can protect the front differential assembly 5. The arc surface of the arc plate 16 can press the mineral blocks downwards and break them, avoiding any impact on the chassis. Furthermore, the arc plate 16 and the sliding plate 11 move towards the front differential assembly 5 through the cooperation of the square groove 12 and the sliding column 13. The arc plate 16 covers the bottom of the front differential assembly 5, thereby achieving overall protection of the front differential assembly 5 and improving the utilization efficiency of the vehicle chassis.

[0027] In practical use, the aforementioned protective structures can also be installed in other locations on the chassis, and adjustments can be made according to specific usage conditions.

[0028] Furthermore, this protective structure is particularly suitable for fragile mineral blocks, as the arc-shaped surface of the arc plate 16 can press the mineral block downwards and break it.

[0029] To achieve a buffering effect, a limiting plate 15 is fixedly connected to the end of the sliding column 13 away from the sliding plate 11. A second spring 14 is fitted onto the outside of the sliding column 13. One end of the second spring 14 is fixedly connected to the limiting plate 15, and the other end of the second spring 14 is fixedly connected to the fixing plate 10. When the arc plate 16 and the sliding plate 11 move towards the front differential assembly 5 through the cooperation of the square groove 12 and the sliding column 13, the limiting plate 15 will compress the second spring 14 to contract. The second spring 14 will then relieve the force and buffer the impact, improving the protective effect of the sliding plate 11 and other structures, and avoiding direct hard contact that could cause high-frequency vibration of the vehicle and its occupants.

[0030] A groove 9 is formed on the lower surface of the horizontal column 4. A slider 6 is slidably disposed inside the groove 9, and a slide plate 11 is fixedly connected to the bottom of the slider 6. A buffer assembly is disposed inside the groove 9, which includes a damper 7 and a first spring 8. One end of the damper 7 is fixedly connected to the inner wall of the groove 9, and the other end of the damper 7 is fixedly connected to the slider 6. The first spring 8 is fitted onto the outside of the damper 7, with one end fixedly connected to the inner wall of the groove 9 and the other end fixedly connected to the slider 6.

[0031] Specifically, when the arc plate 16 and the slide plate 11 move towards the front differential assembly 5 through the cooperation of the square groove 12 and the slide column 13, they will compress the damper 7 and the first spring 8 to contract, and the damper 7 and the first spring 8 will perform a second force relief buffering.

[0032] To improve the crushing effect of the arc plate 16 on the ore block, a blade 17 is fixedly connected to the side of the arc plate 16 away from the front differential assembly 5. Multiple blades 17 are evenly distributed. The blades 17 can crush the ore block by compression.

[0033] This utility model also discloses a personnel carrier for going down into and out of the well, which uses the aforementioned personnel carrier chassis to achieve a protective effect.
