Description

Technical Field

[0001] The invention relates to the field of bulldozer inverter cabinets, and in particular to an installation structure for facilitating the maintenance of an inverter cabinet for an electric-driven bulldozer. Background Art

[0002] With the continuous updating of new energy technology and the vigorous development of the new energy industry, the development of bulldozers in the field of new energy has also entered a new stage. At present, in the mainstream electric bulldozer technical solutions, the inverter cabinet only meets the requirements of its installation and wiring at the level of the whole machine layout. In this way, there is no space for maintenance of the inverter cabinet after installation. If you want to repair the inside of the inverter cabinet, you must enter the bottom of the frame, remove the inverter cabinet installation bolts, and use a lifting device to lift the inverter cabinet out for repair. The process usually requires two to three people to assist each other to complete, which causes great difficulties for drivers or service engineers who are doing outdoor maintenance. Summary of the invention

[0003] In view of the above-mentioned technical deficiencies, an object of the present invention is to provide a mounting structure for an inverter cabinet of an electric-driven bulldozer that is easy to maintain, which can solve the difficulty of inconvenient maintenance of the existing inverter cabinet mounting structure.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The present invention provides an installation structure for an inverter cabinet of an electric-driven bulldozer which is convenient for maintenance. The structure comprises a slide rail base fixed at the bottom of a rear axle box of a frame. The slide rail base comprises a bottom plate and mounting plates on both sides. A heavy-loaded slide rail is fixed on the inner side of the mounting plate, which can give full play to the lateral bending resistance of the heavy-loaded slide rail.

[0006] Sufficient space is reserved between the two mounting plates for installing the inverter cabinet. Two linear sliders that slide with the heavy-load slide rails are provided on both sides of the inverter cabinet to ensure that the inverter cabinet can slide along the heavy-load slide rails. The inverter cabinet is provided with two limit baffles on both sides of the end away from the rear axle box of the rack. The limit baffles are detachably fixed to the end of the mounting plate on the same side.

[0007] When the inverter cabinet inside the rear axle box of the rack needs to be repaired during the use of the whole machine, it is only necessary to remove the bolts fixing the limit baffle and the mounting plate and the relevant wiring harness plugs, and then pull the inverter cabinet outward along the heavy-load slide rail as a whole to inspect the inside of the inverter cabinet;

[0008] After the maintenance is completed, just push the inverter cabinet into the original installation position, fix the limit baffle and the mounting plate, and connect the relevant wiring harness plugs before putting it back into use.

[0009] Preferably, the slide rail base is fixed to the bottom of the rear axle box of the rack by a plurality of bolts and a shock absorbing module. The shock absorbing module fully isolates the impact of the whole machine vibration on the inverter cabinet and the heavy-load slide rail.

[0010] Preferably, the cross section of the heavy-load slide rail is convex, and the cross section of the linear slider is concave, and the two are adapted to each other.

[0011] Preferably, the bottom plate is rectangular, and the four corners of the bottom plate are fixed to the bottom of the rear axle box of the frame by bolts.

[0012] Preferably, the shock absorbing module is a rubber pad with a through hole in the center for the bolt to pass through.

[0013] Preferably, the number of heavy-load slide rails installed on the mounting plate is determined according to site conditions.

[0014] Preferably, a plurality of ribs are fixedly connected between the mounting plate and the bottom plate.

[0015] The present invention also provides an electric drive bulldozer with an inverter cabinet that is easy to maintain, which adopts the installation structure.

[0016] The beneficial effect of the present invention is that the present invention solves the maintenance problem of the inverter cabinet located inside the rear axle box of a new energy bulldozer during the use of the whole machine. This structure ensures the stability and reliability of the inverter cabinet during the use of the whole machine by adding a shock-absorbing module and a limit fixation. At the same time, the maintenance convenience of the inverter cabinet during the use of the whole machine is greatly improved, and a single person can pull the inverter cabinet out of the bulldozer frame for maintenance during the working process of the whole machine, which solves the problem of difficulty in maintaining existing inverters.
