Description

Technical Field

[0001] This utility model belongs to the field of transport vehicle chassis, specifically relating to a reinforced chassis structure for preventing rollover of hazardous chemical transport vehicles. Background Technology

[0002] The anti-rollover chassis structure design of hazardous chemical transport vehicles is crucial for improving vehicle stability and safety, especially when encountering uneven terrain or sharp turns during transportation.

[0003] Existing anti-tipping chassis structures for transport vehicles mostly improve the anti-tipping ability of transport vehicles by enhancing the suspension performance of the chassis. Although this method can prevent transport vehicles from tipping over during driving to a certain extent, the effect is limited. Transport vehicles still have a high possibility of tipping over when driving at high speeds. Moreover, due to the complexity and precision of their suspension structure, traditional anti-tipping structures are very prone to failure and damage when driving on rough roads for a long time, which leads to their poor service life.

[0004] Therefore, in response to the problem that the existing chassis structure of transport vehicles is prone to tipping over during high-speed driving and that its anti-tipping structure has a short service life, a reinforced anti-tipping chassis structure for hazardous chemical transport vehicles has been developed. By adding anti-tipping and reinforcement structures to the chassis structure of the transport vehicle, the possibility of the transport vehicle tipping over during high-speed driving can be effectively reduced, and the service life of the anti-tipping structure can be increased. Utility Model Content

[0005] In order to overcome the problem that the existing transport vehicle chassis structure is prone to tipping over during high-speed driving, and that its anti-tipping structure has a short service life.

One end of the first support frame is hinged to the second hinge interface, and the other end of the first support frame is hinged to the fourth hinge interface. The second support frame is hinged to the first hinge column, and the other end of the second support frame is hinged to the second hinge column. The front end of the connecting frame is fixedly connected to a tire connecting shaft, and an auxiliary wheel is rotatably mounted on the tire connecting shaft.

[0007] Preferably, the transport vehicle chassis includes a base frame, mounting bracket, leaf spring suspension, wheels, differentials, and a gearbox. Three sets of equidistant differentials are installed on the inner wall of the base frame, and the gearbox is installed at the center of the base frame.

[0008] Preferably, wheels are mounted on the connecting shafts at both ends of the differential, and three sets of equidistant leaf spring suspensions are mounted on the lower end of the base frame.

[0024] The main support frame 9, hinged to the mounting frame 2, allows the auxiliary wheels 7, which are rotatably mounted on the connecting frame 8, to be distributed at both ends of the transport vehicle chassis, providing additional auxiliary support to the chassis and preventing it from tipping over during operation. The second support frame 15, hinged at one end to the main support frame 9 and at the other end to the mounting frame 2, together with the first support frame 14, hinged at one end to the connecting frame 8 and at the other end to the mounting frame 2, provides multi-link support for the main support frame 9, ensuring its stability and firmness during use and extending its service life.

[0025] Please see Figure 2 In this embodiment, the transport vehicle chassis includes a base frame 1, a mounting bracket 2, a leaf spring suspension 3, wheels 4, a differential 5, and a gearbox 6. Three sets of equidistantly distributed differentials 5 are mounted on the inner wall of the base frame 1, and the gearbox 6 is mounted at the center of the base frame 1. During use, the differentials 5 and gearbox 6 ensure the torque of the base frame 1 during driving, thus guaranteeing the power of the transport vehicle. Wheels 4 are mounted on the connecting shafts at both ends of the differentials 5, and three sets of equidistantly distributed leaf spring suspensions are mounted on the lower end of the base frame 1. In use, the leaf spring suspension 3 can provide shock absorption for the base frame 1 and the wheels 4 to improve the comfort and passability of the transport vehicle during driving.

In use, the one-to-one correspondence of the leaf spring suspension 3, the wheels 4 and the differential 5 can ensure the rationality and stability of the distribution layout of the wheels 4 on the base frame 1.

[0026] Please see Figures 4-5 In this embodiment, the lower end of the mounting bracket 2 is provided with a mounting groove 17. The inner wall of the mounting groove 17 fits against the front and rear ends of the base frame 1. In use, the mounting bracket 2 and the mounting groove 17 can facilitate the user to select the installation position according to the structure of different transport vehicle chassis, so as to meet the anti-tipping needs of different transport vehicle chassis. The mounting bracket 2 is fixedly installed on the base frame 1 by the second fixing bolt 20 and the first fixing bolt 19. The second fixing bolt 20 and the first fixing bolt 19 are threaded together.

In use, the alloy steel mounting frame 2, connecting frame 8, first support frame 14 and second support frame 15 can ensure the service life and strength of the anti-rollover structure composed of them.

[0028] Before use, first use the first fixing bolt 19 and the second fixing bolt 20 to fit the mounting bracket 2 onto the front and rear edges of the base frame 1, and make the outer wall of the auxiliary wheel 7 contact the ground;

[0029] During the operation of the transport vehicle, the main support frame 9 can drive the connecting frame 8 and the auxiliary wheels 7 on it to provide additional support for the chassis of the transport vehicle, and can rotate and adjust the angle according to the tilt angle of the chassis of the transport vehicle, thereby realizing the function of preventing the chassis of the transport vehicle from tipping over.

[0030] Meanwhile, the first support frame 14 and the second support frame 15, made of high-strength alloy steel, can provide multi-link support for the main support frame 9 to ensure the stability and firmness of the main support frame 9 during use, thereby ensuring its service life.

[0031] Through the above steps, the main support frame 9, which is hinged to the mounting frame 2, allows the auxiliary wheels 7, which are rotatably mounted on the connecting frame 8, to be distributed at both ends of the transport vehicle chassis, providing additional auxiliary support for the transport vehicle chassis and thus preventing the transport vehicle chassis from tipping over during driving. The second support frame 15, which is hinged to the main support frame 9 at one end and to the mounting frame 2 at the other end, together with the first support frame 14, which is hinged to the connecting frame 8 at one end and to the mounting frame 2 at the other end, can provide multi-link support for the main support frame 9, ensuring the stability and firmness of the main support frame 9 during use and guaranteeing its service life. This solves the problem that the existing transport vehicle chassis structure is prone to tipping over during high-speed driving and that its anti-tipping structure has a short service life.
