[0022] The utility model will be further described below in combination with the drawings.

[0023] As Figures 1-5The utility model provides a tracked vehicle balance elbow dismounting device, it includes screw plug 2, the screw rod 3 of setting in screw plug 2, with the support plate 4 of screw rod 3 cooperation arrangement and the support rod 1 of setting in support plate 4, one end of screw rod 3 sets up the clamping block 301, the other end sets up the screwing head 302, the clamping block 301 sets up inside screw plug 2, set up the clamping groove 201 on screw plug 2, the clamping block 301 sets up inside clamping groove 201, the outside of screw plug 2 sets up the screw, the outside of screw plug 2 and balance elbow middle hole screw thread cooperation, the middle part of support plate 4 sets up the screw groove, the screw groove and screw rod 3 screw thread cooperation, when using, first screw rod 3 passes through screw plug 2, the clamping block 301 sets up in the clamping groove 201 of screw plug 2, the shape matching of clamping block 301 and clamping groove 201 is cylindrical, the clamping block 301 can rotate freely in clamping groove 201, namely in the process of rotating screw rod 3, screw plug 2 will not follow the rotation or form influence, screw plug 2 is mainly used in balance elbow dismounting operation, through screw rod 3 rotation, support plate 4 does not move, and the center of support plate 4 and screw rod 3 screw thread cooperation, utilize the removal of clamping block 301 to drive the removal of screw plug 2, and then pull out the balance elbow.

[0024] The support plate 4 is provided with a through slot, and the front end of the support rod 1 is provided with a threaded segment; the through slot 401 is two, and the support rod 1 is two; the threaded segment at the front end of the support rod 1 is in screw thread cooperation with the holes on the two sides of the balance elbow; during the dismounting operation, the threaded segment of the support rod 1 needs to be installed into the threaded holes on the two sides of the balance elbow, so as to play a limiting and supporting role.

[0025] The outer side of the screw rod 3 is sleeved with an axle cylinder 5, and the axle cylinder 5 is arranged between the support plate 4 and the balance elbow; the axle cylinder 5 is mainly applied to the installation operation of the balance elbow; the axle cylinder 5 abuts against the balance elbow; by rotating the screw rod 3, the support plate 4 drives the axle cylinder 5 to be pressed; the support plate 4 presses the axle cylinder 5; the axle cylinder 5 presses the balance elbow; and the stable installation of the balance elbow is realized.

[0026] The outer side of the screw rod 3 is sleeved with a hollow hydraulic jack, which can also realize the effect of dismounting the balance elbow of the utility model; however, the weight, complexity and cost of the equipment need to be increased correspondingly; and similar schemes also belong to the protection range of the utility model.
