Description

Technical Field

[0001] The present application relates to the technical field of carriages, for example, to a fixing device for a dump truck carriage. Background Art

[0002] There are many special-purpose vehicles with dump functions, such as various dump trucks, sanitation vehicles, etc. The sub-beam at the bottom of the car body is flipped around the frame sub-beam through a flip hinge support to achieve the dump function; the connection between the sub-beam at the bottom of the car body and the frame sub-beam is the hinge support at the rear and the hydraulic cylinder in front of it. At the same time, a guide plate is arranged in front of the frame sub-beam to prevent the sub-beam at the bottom of the car body from not falling correctly onto the frame sub-beam, causing dislocation and twisting. This guide plate structure is widely used because of its simple installation, ability to achieve lateral positioning, and low maintenance cost.

[0003] However, the existing guide plate is only used to guide and laterally fix the car body, and cannot fix the front end of the car body to the front end of the frame. This form can cope with low-speed driving, but when driving at high speed or in severe bumpy road conditions, it cannot offset the up and down shock forces caused by the bumps, and the up and down movement of the car body cannot be restricted, making the car body unstable and lacking protection, resulting in deformation or damage to the car body. Utility Model Content

[0004] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0005] The disclosed embodiment provides a dump truck compartment fixing device to solve the problem that the up and down shock forces generated by the bumps cannot be offset, making the compartment unstable and lacking in protection.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A dump truck compartment fixing device comprises a compartment seat, a frame seat and a hook lock, wherein the compartment seat is fixed to one side of the compartment bottom sub-beam of the dump truck compartment, the frame seat is arranged on one side of the frame sub-beam and corresponds to the compartment seat, a functional cavity is arranged in the middle of the frame seat, a hook lock is arranged inside the functional cavity, an outwardly tilted flap is arranged on the top of the hook lock, and an arc-shaped process locking arc is extended downward from the bottom of the tilted flap to form an arc, pin plates are arranged at the same position on both sides of the hook lock, and the pin plates are located at the inner side of the functional cavity, screw pins are arranged at the positions corresponding to the pin plates on both sides of the functional cavity, and the screw pins move through the functional cavity The side wall of the cavity is fixedly connected with the corresponding pin plate through a thread, and then the hook lock part is confined in the functional cavity through the cooperation of the screw pin and the pin plate, and can only swing up and down in the functional cavity with the screw pin as the axis. A compression rubber block is fixedly arranged inside the functional cavity. The compression rubber block has elastic stress, which will resist the inner side of the hook lock part to force its top to keep swinging upward. The top position of the hook lock part corresponds to the compartment seat. A positioning lock shaft is arranged on the inner side of the compartment seat. When the compartment of the dump truck is lifted and dropped, the positioning lock shaft will first contact the inner side of the inclined flap and exert downward pressure on it. This will cause the hook lock to swing downward with the screw pins on both sides as the axis. When the downward movement of the positioning lock shaft is introduced into the process lock arc, the operation of guiding the car body into contact with the frame is completed. When the positioning lock shaft moves into the process lock arc, the hook lock piece will swing upward and reset under the action of the elastic stress of the compressed rubber block, so as to achieve the purpose of buckling the positioning lock shaft into the process lock arc. A stop plate extending to the bottom of the frame seat is provided on the bottom side of the hook lock piece, and a locking cylinder is provided at the bottom of the frame seat. The output end of the locking cylinder corresponds to the stop plate and resists the stop plate. During the lifting and resetting process of the car body, the locking cylinder is in a retracted and closed state. When the car is reset, the positioning lock shaft is buckled into the process lock arc by the hook lock part. The staff can start the locking cylinder through the central control to resist the stop plate, and then fix the hook lock part, so that it can no longer swing up and down, and can effectively prevent the positioning lock shaft from escaping from the process lock arc, thereby achieving the purpose of locking the car after the car is reset. It can effectively limit the range of the car's shaking after receiving the upward impact, and offset the force generated when the car is driving on bad road conditions. It can effectively protect the car, avoid deformation and wear caused by the bumpy force, and increase stability.

[0008] Furthermore, a padlock plate is provided on one side of the compartment seat. The padlock plate is fan-shaped and one end of the padlock plate is movably sleeved on the part of the positioning lock shaft located outside the compartment seat, and an arc-shaped arc lock groove is opened on the bottom side of the other end. The padlock plate is connected to the hook lock member.

[0009] Furthermore, a round convex is arranged on the outer side of the hook lock piece corresponding to the process lock arc, and a locking rod is fixedly inserted into the round convex, and the arc lock groove is buckled with the locking rod and the width of the arc lock groove is adapted to the diameter of the locking rod. After the car resets the process lock arc and buckles the positioning lock shaft in, the staff can make the arc lock groove buckle with the locking rod by its own gravity, thereby realizing the fixed connection between the car seat and the hook lock piece, thereby further realizing the limitation of the hook lock piece, making it unable to swing up and down, preventing the positioning lock shaft from escaping from the process lock arc, reducing the pressure of the locking cylinder, and at the same time, the padlock plate and The fixed connection of the hook lock is equivalent to realizing a fixed connection between the frame and the car body. According to the connection method, the lateral movement range of the car body can be limited, and the lateral force generated by the shaking can be offset to achieve the purpose of further protecting the car body. The padlock plate has a variety of installation methods. In addition to the above methods, it can also be installed by buckling the screw pin through the arc lock groove, or by sleeved the padlock plate on the lock rod, and then buckling the positioning pin shaft through the arc lock groove. Both methods can achieve a fixed connection between the car body and the frame. The installation method of the padlock plate is flexible and diversified to increase practicality.

[0010] Furthermore, one side of the box seat is fixedly connected to the side wall of the box bottom sub-beam by welding, and positioning bins are provided on both sides of the functional cavity in the frame seat, and a plurality of fixing screws are provided in the positioning bins, and the frame seat is fixedly connected to the frame sub-beam by fixing screws.
