Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and implementation.

[0013] As shown in Figure 2, the device for preventing the loosening of the broken wall of the cone crusher proposed by a preferred embodiment of the present invention includes a compression nut II2 with a large pitch and a large diameter, a compression nut I1 with a small pitch and a small diameter, and a compression nut II2 It is integrated with the compression nut I1 with a bolt 3; a jacking bolt 4 is arranged in the compression nut II2 for tightening the compression nut I1. The selection principle of the thread pitch in this embodiment is to use a thread with a smaller pitch as much as possible on the premise of meeting the thread strength requirements.

[0014] The method for preventing the broken wall of the cone crusher from loosening according to the present invention will be described below in conjunction with the accompanying draw...

Abstract

The present invention discloses a method for preventing crushing wall of cone crusher from loosening. It is characterized by that said method includes the following steps; screwing a holddown nut with small pitch and small diameter into said cone body interior, then screwing another holddown nut with large pitch and large diameter into said cone body interior; after the crushing wall is tightly pressed, using screw bolt to make the above-mentioned holddown nuts be connected together; then screwing puller bolt into the holddown nut with large pitch and large diameter until the holddown nut with small pitch and small diameter is tightly pressed.

Description

technical field [0001] The invention relates to a method for preventing the broken wall of the cone crusher from loosening; in addition, the invention also relates to a device for preventing the broken wall of the cone crusher from loosening. Background technique [0002] Chinese patent CN2619716Y disclosed a cone crusher on June 9, 2004, including a frame, a transmission shaft, an eccentric sleeve assembly, a main shaft, a moving cone assembly, a rolling mortar wall, an adjustment sleeve, a support sleeve, a feed hopper, and a hydraulic system. The transmission shaft is arranged in the transmission shaft frame through sliding bearings, and the two ends of the transmission shaft are fixed with a small bevel gear and a pulley, and the small bevel gear meshes with the large bevel gear fixed on the eccentric sleeve. It is characterized in that the moving cone assembly The broken wall is set on the body, and fixed by the locking bolt 23 through the cutting ring, the locking bolt...
