[0003] The utility model aims to provide a main engine wheel movable rim puller, which ensures that the movable rim can be synchronously withdrawn from the main engine wheel, and ensures that the disassembly process does not generate metal-to-metal friction on the movable rim and the risk of deformation of the movable rim due to improper disassembly method.

[0004] In order to realize the above-mentioned technical features, the purpose of the utility model is achieved as follows: the main wheel movable rim puller comprises symmetrically arranged cross beams, slide rails are arranged on the cross beams, threaded sleeves are arranged in the middle parts of the two cross beams, a screw is installed on the threaded sleeve through threaded transmission, and a top plate is installed on the bottom end of the screw through a ball head connection structure; a slider structure is installed on the slide rail through sliding cooperation, and a clamp is fixedly installed on the slider structure.

[0005] A hexagonal column is arranged on the top of the screw rod.

[0006] The ball head connection structure includes a ball head arranged at the end of the screw rod, the ball head cooperates with the spherical groove at the center of the top of the top plate, and a ball head pressure plate is installed at the top of the ball head, and the ball head pressure plate is fixedly installed at the center of the top of the top plate by multiple locking screws.

[0007] The ball head pressure plate is processed with an open groove, and the open groove can pass through the shaft ring on the screw.

[0008] The back of the top plate is provided with uniformly distributed reinforcing ribs.

[0009] The slider structure comprises slide rail plates symmetrically arranged on two outer sides of the slide rail, and the bottom end of the slide rail plate is fixedly mounted with a clamping claw through a first bolt assembly and a second bolt assembly.

[0010] The first bolt assembly and the second bolt assembly include bolts, and the ends of the bolts are fixedly mounted with flat washers and spring washers through nuts.

[0011] The utility model has the following beneficial effects:

[0012] 1. The utility model ensures that the movable wheel rim can be synchronously withdrawn from the main wheel.

[0013] 2. The contact parts of the utility model with the movable wheel rim are wrapped or protected with soft materials to ensure that the disassembly process does not generate metal-to-metal friction on the movable wheel rim and the risk of deformation of the movable wheel rim due to improper disassembly methods.

[0014] 3. During disassembly, the main force point of the utility model only needs to be rotated by the screw rod to bring out the movable rim, avoiding the use of brute force and reducing the workload of the staff.

[0015] 4. The screw rod of the utility model adopts trapezoidal thread to ensure that the equipment has a self-locking function, so as to avoid sudden loss of strength by personnel, resulting in the puller falling off or the movable rim falling off and causing injuries to personnel.
