A chassis and superstructure quick disassembly and assembly device

Abstract

This utility model provides a quick assembly / disassembly device for chassis and superstructure, including a rotary locking beam. The superstructure is placed on the upper end of the rotary locking beam, and rotary locking devices are provided at both ends of the rotary locking beam. A U-shaped plate is provided at the lower end of the rotary locking beam, and the U-shaped plate is connected to the vehicle frame. The rotary locking devices are connected to the superstructure. The rotary locking beam installed on the vehicle frame serves as the mounting surface for the superstructure. The rotary locking devices at both ends of the rotary locking beam are used in conjunction with the corner pieces at the bottom of the superstructure.

Furthermore, since the superstructure can be quickly assembled and disassembled, parts of the chassis that are difficult to repair can be repaired by removing the superstructure, thus improving the maintenance performance of the chassis.

Description

Technical Field

[0001] This utility model relates to a quick disassembly and assembly device for chassis and superstructure, and pertains to the field of vehicle chassis technology. Background Technology

[0002] Military off-road vehicles are used for various strategic missions, so the equipment mounted on their chassis varies. Currently, the connection between the chassis and the superstructure is mostly achieved through a subframe connection. This involves using thrust plates, connecting brackets, and U-bolts to connect the frame to the subframe, and then using the subframe to connect the chassis and the superstructure.

[0003] However, the existing chassis and superstructure connection method is relatively cumbersome, and the installation and disassembly time is long; after the equipment is installed, the chassis is extremely difficult to repair. At the same time, this connection method requires the superstructure to adapt to the chassis connection, which is relatively unique for the superstructure. Utility Model Content

[0004] To address the aforementioned problems arising from actual manufacturing processes, this utility model provides a quick assembly / disassembly device for the chassis and superstructure. The specific technical solution is as follows:

[0005] A quick assembly / disassembly device for chassis and superstructure includes a rotary locking beam, with the superstructure placed on the upper end of the rotary locking beam. Rotary locking devices are provided at both ends of the rotary locking beam, and a U-shaped plate is provided at the lower end of the rotary locking beam. The U-shaped plate is connected to the vehicle frame, and the rotary locking devices are connected to the superstructure.

[0006] Furthermore, the upper part is equipped with a corner piece, and the rotary locking device is inserted into the corner piece.

[0007] Furthermore, the upper end of the rotary locking device is provided with a lock head, the lower end of the rotary locking device is provided with a rotating handle, and the rotating handle is located at the lower end of the rotary locking beam. A support sleeve is sleeved between the lock head and the rotating handle, the support sleeve is embedded in the rotary locking beam, and the lock head is inserted into the corner piece and connected to the corner piece.

[0008] Furthermore, the rotating handle is provided with a locking bolt, and the lower end of the rotating locking beam is provided with a locking threaded hole and a disassembly threaded hole, and the locking bolt is connected to the locking threaded hole or the disassembly threaded hole.

[0009] Furthermore, the corner piece is provided with a locking step, and the lock head is inserted into the corner piece and abuts against the locking step.

[0010] Furthermore, the corner piece is provided with an observation hole.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] The rotary locking beam mounted on the frame serves as the mounting surface for the superstructure. Rotary locking devices are installed at both ends of the beam, engaging with the corner fittings at the bottom of the superstructure. A locking bolt is mounted on the rotating handle, and the lower end of the beam has both locking and unlocking threaded holes. When the superstructure needs to be connected to the chassis, the locking head is inserted into the corner fitting, and the rotating handle is turned to engage the locking step, thus locking the superstructure. The locking bolt is then engaged with the locking threaded hole for final tightening. When the superstructure needs to be separated from the chassis, the locking head is unlocked by rotating the rotating handle, and the locking bolt is then engaged with the unlocking threaded hole to separate the superstructure from the chassis.

[0013] Simply by removing the locking bolts, the superstructure can be separated from and connected to the chassis by rotating the handle, greatly improving the loading efficiency of the superstructure. At the same time, different superstructure equipment can be mounted on the chassis to meet the chassis requirements in special circumstances. Furthermore, since the superstructure can be quickly disassembled and assembled, parts that are difficult to repair on the chassis can be repaired by removing the superstructure, thus improving the chassis's maintainability.

[0020] 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.

[0021] like Figures 1-4As shown, a quick assembly and disassembly device for chassis and superstructure includes a rotary locking beam 2, a superstructure 4 placed on the upper end of the rotary locking beam 2, rotary locking devices 1 at both ends of the rotary locking beam 2, a U-shaped plate 3 at the lower end of the rotary locking beam 2, the U-shaped plate 3 being connected to the vehicle frame, and the rotary locking devices 1 being connected to the superstructure 4.
