Description

Technical Field

[0001] This utility model relates to the field of tractor gantry technology, specifically to a reinforced gantry that can be disassembled and assembled. Background Technology

[0002] The tractor's gantry is located in front of the cab. The engine is located on one side of the gantry, and the steering gear inside the cab is installed on the other side.

[0003] Traditional gantry frames are mostly made of sheet metal or welded frame as one piece. During installation, the gantry frame is first fixed to the chassis or gearbox housing of the tractor, and then other components such as the steering gear on the gantry frame are installed, as well as hydraulic lines are laid near the gantry frame.

[0004] Because the gantry frame has a closed structure, the steering hoses must pass through a sealing plate to be installed on the steering gear. If the steering gear and hoses on the steering gear bracket are installed first, the traditional one-piece gantry frame cannot avoid accommodating the hoses during retrofitting, causing installation difficulties. If the gantry frame is installed first, the space between the gantry frame and the engine, and between the gantry frame and the steering gear bracket, is narrow, making hydraulic line installation difficult and adjustments during and after installation challenging. Furthermore, during maintenance, the hydraulic lines are difficult to disassemble and adjust, making the operation complex. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to reduce the difficulty of installation and maintenance of structures such as steering oil pipes and hydraulic pipelines at the gantry.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] This utility model provides a detachable and assembleable reinforced gantry frame, including a gantry frame body. The inner side of the gantry frame body is provided with a windbreak partition and a reinforcing beam plate. The edge of the windbreak partition is connected to the gantry frame body. The lower part of the windbreak partition is provided with a notch, and a first sealing plate is provided at the notch. The edge of the first sealing plate is connected to the windbreak partition. The reinforcing beam plate is located on one side of the windbreak partition, and both ends of the reinforcing beam plate are connected to the gantry frame body. The reinforcing beam plate is provided with a connecting part that can be used to connect to an external steering gear mounting bracket.

[0008] The beneficial effects of this utility model are:

[0009] This invention facilitates the installation of steering oil pipes, hydraulic lines, and other structures through the notch at the bottom of the windshield partition, making installation convenient. Maintenance can be performed simply by removing the first sealing plate, simplifying operation. The windshield partition and the first sealing plate ensure isolation between the cab and the engine compartment. The connection of the reinforcing beam provides an installation position for the external steering gear mounting bracket, ensuring convenient and compact installation while maintaining the mounting strength of the steering gear mounting bracket.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the lower part of the gantry frame is provided with a middle beam assembly, which has a first bolt hole for connecting to an external frame; the lower ends of the gantry frame are provided with second bolt holes for connecting to an external frame; the lower edge of the windbreak is welded to the upper side of the middle beam assembly.

[0016] During manufacturing, the guard plate can be pre-connected to the gantry frame body. Positioning is achieved through the guard plate, which facilitates the installation of the intermediate beam body and the first sealing plate, resulting in high manufacturing precision.

[0017] Furthermore, the guard plate is made of angle steel, and the middle beam body is located inside the corner of the guard plate. The horizontal width of the guard plate is the same as the horizontal width of the middle beam body.

[0018] The corner structure of the guard plate positions the intermediate beam body. The horizontal width of the guard plate is the same as the horizontal width of the intermediate beam body, which ensures the levelness of the intermediate beam body and the gantry frame, resulting in high installation accuracy.
