Description

Device for riveting electric shovel to push dead band brake and smooth wheel band brake shoe Technical Field The utility model relates to the technical field of brake shoe riveting, in particular to a device for riveting a brake shoe of an electric shovel pushing dead brake and a smooth wheel brake. Background The WK-4 electric shovel is a single-meter forward shovel and crawler-type full-rotation electric excavator, is mainly used for mining, and can efficiently excavate and transport ores or rocks. Because the electric shovel has a severe working environment, all parts of the pushing part bear larger loads, particularly, the dead lock wheel and the pushing motor smooth wheel are main stress parts of the pushing part, and the brake shoe rack is a main part of the pushing braking part and is easy to wear and damage due to the acting force of high-speed rotation of the dead lock wheel and the pushing motor smooth wheel. In the prior art, the riveting operation of brake shoe and brake shoe rack is mostly carried out on bench vice, because the radian of bench vice is inconsistent with the radian of brake shoe rack, leads to the unable inseparable laminating of brake shoe to install on the brake shoe rack, and then the difficult riveting of rivet when leading to riveting, and the brake shoe is broken easily after using a period, even the brake shoe is together drops with the rivet easily, finally leads to frequent change brake shoe for the electric shovel is stopped to use, seriously influences production. In summary, how to solve the problems that the brake shoe is not tightly attached to the brake shoe holder when the brake shoe is mounted on the bench vice, and is not tightly fastened during riveting, so that the brake shoe is easy to break and easily fall off together with the rivet is a problem to be solved by those skilled in the art. Disclosure of utility model Therefore, the utility model aims to provide a device for riveting a brake shoe of a dead band brake and a brake shoe of a smooth wheel by a shovel, which has large follow-up property, is convenient and quick to use, can ensure tight joint of a brake shoe and a brake shoe rack, and can fasten rivets, so that the problems of broken brake shoe and falling off of a brake Pi Yi and the rivets are avoided. In order to achieve the above object, the present utility model provides the following technical solutions: A device for riveting an electric shovel pushing against a dead band brake and a smooth wheel band brake shoe, comprising: a movable platform movable along the ground; The dead lock wheel comprises an arc-shaped part and a supporting part horizontally positioned below the arc-shaped part, the supporting part is arranged on the movable platform, at least two gaps are formed in the arc-shaped part at intervals along the circumferential direction, and the gaps are used for installing rivets; The pushing motor light wheel is arranged on the movable platform, and the pushing motor light wheel and the dead band brake wheel are distributed in parallel. In one embodiment, the support is welded to the movable platform. In one embodiment, the pushing motor is optically welded on the movable platform. In one embodiment, one side of the arcuate portion is cut with different sizes of the notches distributed corresponding to the rivet hole locations of the brake head. In one embodiment, a baffle is provided on the other side of the arcuate portion. In one embodiment, the baffle is welded to the arcuate portion. In one embodiment, the movable platform comprises a rectangular steel plate and universal wheels rotatably arranged at four corners of the steel plate. In one embodiment, the universal wheel comprises a rubber material. In one embodiment, the dead band wheel and the push motor light wheel are both scrap structural members. When the device for riveting the electric shovel to push the dead band brake and the smooth wheel band brake shoe is used, firstly, an operator can cut the brake shoe into a size matched with the length and the width of the brake shoe rack. Then, the brake shoe is placed on the side of the dead band brake wheel provided with the notch. Then, the brake shoe holder is placed on the brake shoe, and an electric drill is used for drilling holes downwards from the rivet holes of the brake shoe holder, and the electric drill can drill through holes aligned with the rivet holes on the brake shoe and drill through the brake shoe. Thereafter, the operator penetrates the rivet hole and the through-hole, and preliminary installation operations of the rivet can be sequentially performed from the middle to both sides of the brake shoe. Finally, an operator can move the preliminarily fixed brake shoe holder and brake shoe to the push motor smooth wheel, then rivet fastening operation is sequentially carried out on the rivets, and moreover, because the radian of the top of the motor smooth wheel and the bottom of the brake shoe is matched, the rive
