Description

Technical Field

[0001] The invention belongs to the technical field of loader design, and in particular relates to an auxiliary box for a loader. Background Art

[0002] Wheel loaders are mainly used for shoveling and transporting materials in mines, roads and bridges, construction, docks, material yards and other places. The working environment is relatively harsh, with serious sand and dust pollution and rain erosion. The installation of hydraulic accumulators and electrical control boxes of many loader models on the market is troublesome, and the protection measures are not well designed. Some are even directly exposed to the external environment, lacking protection designs such as anti-dust, anti-rain, and anti-smashing, which can easily cause damage to the hydraulic accumulator and electrical control box, thus affecting the safety and stability of the loader operation. At the same time, it has an adverse effect on the neatness and aesthetics of the loader's appearance. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention provides a loader auxiliary box.

[0004] The present invention is implemented as follows: a loader auxiliary box comprises a box body, a connecting piece connected to the loader frame is provided on the back of the box body; a left bracket and a right bracket of a platform pedal are welded on both sides of the upper part of the box body, and a mounting plate is welded on the upper space inside the box body, and the mounting plate divides the box body into two independent mounting cavities; an upper opening is provided on the upper part of the box body; an upper cover plate is connected to the box body on one side of the upper opening through a first hinge, a handle lock is installed on the upper cover plate, and a handle lock is installed between the upper cover plate and the mounting plate. A support rod is connected, and an upper footrest component is installed on the inner upper part of the box body by bolts; the bottom of the box body is connected to a flip door by a second hinge; handles are welded on both sides of the flip door, and a lower footrest assembly is welded on the front end of the flip door; a telescopic pull rod for controlling the opening angle of the flip door is installed between the flip door and the box body; flip door limit locks are provided on both sides of the box body; a rectangular side opening is provided on the right side of the box body, and a side door is connected to the side opening by a third hinge; a side door lock is installed on the side door.

[0005] Preferably, the upper opening is surrounded by a first flange protruding outwards, and a first sealing strip is mounted on the first flange. The first flange protruding outwards acts as a water barrier, preventing rainwater from leaking into the box from the upper opening, thereby preventing the original parts inside the box from being damaged by rainwater.

[0006] Preferably, the edge of the side opening is provided with a second flange protruding outwards, and a second sealing strip is wrapped around the second flange. The second flange protruding outwards plays a role of water blocking, which can prevent rainwater from leaking into the box from the side opening, and avoid damage to the original parts inside the box due to rainwater entering.

[0007] The advantages and technical effects of the present invention are as follows: Compared with the existing loader related technologies, the loader auxiliary box of the present invention can better protect the hydraulic accumulator and the electrical control box, making them work safely, cleanly and stably, saving time during maintenance and repair, improving work efficiency, safe and convenient operation, and can improve the practicality of the loader auxiliary box, reduce the probability of damage to the accumulator and the electrical control box, thereby saving maintenance costs and having certain economic benefits.

The present invention provides a reversible wheel loader auxiliary box to solve the existing technical problems, which can realize the up and down flipping and opening of the flip box door, and the electrical control box and the hydraulic accumulator can be installed inside the box. The auxiliary box is installed on the side of the loader frame, and the pedal platform and handrail are installed on the left and right brackets. The upper part is reserved for storing and installing the electrical control box, and the lower space can accommodate and surround the hydraulic accumulator. The auxiliary box is welded with steel plates as a whole, and is composed of a box body, left and right brackets, support rods, upper cover plate, handle lock, upper footrest, lower footrest assembly, flip box door, lock, side door, handle, telescopic pull rod, sealing strip and hinge. The flip door is connected to the mounting plate on the box body by a hinge, and can be flipped up and down to open and close. When the accumulator needs to be installed and maintained, the door can be opened very conveniently. The upper part of the box body can be used to install the electrical control box, and the upper cover plate can be opened and closed up and down, which is convenient for the inspection and maintenance of the control box. The upper part of the pedal bracket of the box body can be installed with a pedal platform for operators to walk or stay, as well as upper and lower handrails. An observation window and a side door are provided on the right side of the box body, so that the hydraulic components inside the box body can be checked at any time to see if there are any abnormal conditions such as oil leakage or looseness. The rear part of the box body is fixed to the frame by bolts. The internal space of the box body can accommodate a hydraulic accumulator installed at the corresponding position of the frame. When the hydraulic accumulator and the electrical control box need to be maintained and repaired, the flip door and the upper cover plate can be quickly opened, which is safe, convenient and quick, and greatly improves work efficiency. The present invention is described in detail below in conjunction with relevant drawings.
