Technical Field
[0001] The utility model relates to the technical field of gearboxes, and specifically relates to a gearbox for a trackless mine vehicle with a noise reduction structure. Background Art
[0002] Trackless transport vehicles, most of which are rubber-tired self-propelled transport equipment driven by diesel engines or transport equipment driven by cable-towed motors, are used for the loading and transportation of rocks, ores, and materials. There are self-propelled mine cars, load-haul-dumpers suitable for medium and short-distance transportation, or underground mining trucks for long-distance transportation with a one-way haul distance of up to 2,000 - 3,000 meters.
[0003] A vehicle gearbox is a device for changing the speed ratio and direction of motion, which is used in automobiles, tractors, ships, machine tools, and various machines to change the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft according to different working conditions. A gearbox with gear transmission generally consists of a housing and several pairs of gears.
[0004] However, when working in mines, due to the high noise generated by the gearbox during operation, the construction environment is affected. At the same time, since there are many stones on the mine road surface, when the vehicle is driving at high speed, the gearbox cannot be protected, and it is easy for splashing stones to damage the gearbox.
[0005] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model
[0006] In view of the deficiencies and defects in the prior art in the above-mentioned background art, such as the high noise generated by the gearbox during operation, which affects the construction environment, and the inability to protect the gearbox, making it easy for splashing stones to damage the gearbox.
[0007] A gearbox for a trackless mine vehicle with a noise reduction structure disclosed by the utility model includes a noise reduction bottom plate. Two noise reduction side plates one and two noise reduction side plates two are fixedly connected to the upper surface of the noise reduction bottom plate. On each side of the two noise reduction side plates one facing each other, two sliding grooves one are opened. A sliding block one is slidably connected to the inner wall of each sliding groove one. On each side of the two noise reduction side plates two facing each other, a sliding groove two is opened. A sliding block two is slidably connected to the inner wall of each sliding groove two. A noise reduction top plate is arranged above the noise reduction bottom plate. The upper surfaces of each sliding block one and sliding block two are fixedly connected to the bottom surface of the noise reduction top plate.
[0008] Further, a gearbox body is arranged below the noise reduction top plate. Two limiting grooves are opened on the bottom surface of the gearbox body. A limiting block is in sliding contact with the inner wall of each limiting groove. The bottom surface of each limiting block is fixedly connected to the upper surface of the noise reduction bottom plate.
[0009] Further, both the left side surface and the right side surface of the noise reduction bottom plate are fixedly connected with two support rods, and a locking member is threadedly connected to the inner wall of each support rod.
[0010] Further, a third sliding groove is formed in the upper surface of each support rod, a third sliding block is slidably connected to the inner wall of each third sliding groove, and a clamping block is fixedly connected to the top end of each third sliding block.
[0011] Further, a plurality of card slots arranged at equal intervals are formed in the upper surface of the noise reduction top plate, and the outer surface of each clamping block is slidably connected to the inner wall of the corresponding card slot.
[0012] Further, two connecting blocks are fixedly connected to both the left side surface and the right side surface of the transmission body, and the outer surface of each connecting block is slidably connected to the inner wall of the corresponding first sliding groove.
[0013] Further, an input shaft is installed on the front surface of the transmission body, an output shaft is installed on the back surface of the transmission body, annular members are fixedly sleeved on the outer surfaces of the input shaft and the output shaft, and the outer surface of each annular member is sleeved with the inner wall of the corresponding second sliding groove.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] 1. By providing components such as a noise reduction bottom plate, a first noise reduction side plate, a second noise reduction side plate, and a noise reduction top plate, the noise reduction bottom plate is installed, and the first noise reduction side plate and the second noise reduction side plate are installed on the upper surface of the noise reduction bottom plate. The transmission body is placed on the surface of the noise reduction bottom plate. By moving the noise reduction top plate to drive the corresponding first sliding block and second sliding block to move, through the connection between the first sliding block and the second sliding block and the first sliding groove and the second sliding groove, the assembly of the noise reduction structure is realized, and the effect that the device can reduce noise is achieved. When working in a mine, the running transmission makes a large noise, affecting the construction environment, and can protect the transmission, preventing the stones splashed when the vehicle is driving at high speed in the mine from damaging the transmission.
[0016] 2. By providing components such as support rods, third sliding blocks, clamping blocks, and card slots, after assembling the noise reduction top plate, move the corresponding third sliding block to drive the corresponding clamping block to be connected with the corresponding card slot.
