In an embodiment, an output end of the clamping cylinder 133 is connected to the first clamping member 131, and the output end of the clamping cylinder 133 drives the first clamping member 131 to approach or separate from the second clamping member 132. That is, in the present embodiment, the second clamping member 132 is kept stationary with respect to the fixing frame 11, and the first clamping member 131 is moved toward or away from the second clamping member 132 by the driving of the clamping cylinder 133 to achieve clamping and unclamping. The advantage of this arrangement is that the clamping and releasing actions of the clamping assembly 13 can be achieved by only one clamping cylinder 133, and the amount of the clamping cylinder 133 can be reduced, and the production cost and the use cost can be reduced. Of course, in other embodiments, two clamping cylinders 133 may be provided, and the output ends of the two clamping cylinders 133 are respectively connected to the first clamping member 131 and the second clamping member 132, and the two clamping cylinders 133 move simultaneously to achieve clamping or separation.
Further, the clamping cylinder 133 is disposed on the inner wall of the second clamping member 132, and an output end of the clamping cylinder 133 is connected to the inner wall of the first clamping member 131. Specifically, in the present embodiment, the length and width of the clamping cylinder 133 are smaller than or equal to the length and width of the second clamping member 132 to ensure that the clamping cylinder 133 is sized beyond the second clamping member 132, and the height of the clamping cylinder 133 is smaller than the thickness of the axle housing 21 to ensure that the lowermost gap of the first clamping member 131 and the second clamping member 132 in the clamped state can clamp the axle housing 21. The advantage of setting up like this lies in, just can form the protection to clamping cylinder 133, avoid other parts such as spanner that drop to damage clamping cylinder 133, on the other hand because clamping cylinder 133's output is connected with first holder 131's inner wall, this makes clamping cylinder 133's output only need less stroke just can realize that first holder 131 and second holder 132 press from both sides tightly, can realize quick clamp and loosen improvement efficiency, simultaneously, clamping cylinder 133's output stroke is little, this makes clamping cylinder 133's cost end, can reduce production and use cost. Of course, in other embodiments, the output end of the clamping cylinder 133 may be connected to the side wall of the first clamping member 131, such that the output end of the clamping cylinder 133 is further than the thickness of the first clamping member 131.
Further, the ends of the first clamping member 131 and the second clamping member 132 away from the rotating base plate 12 are in a jaw shape. Specifically, the extension line of one end of the first clamping member 131 far away from the rotating bottom plate 12 and the extension line of the clamping cylinder 133 intersect to form an acute angle, and the extension line of one end of the second clamping member 132 far away from the rotating bottom plate 12 and the extension line of the clamping cylinder 133 intersect to form an acute angle, so that the clamping force of the clamping assembly 13 in the clamping state is higher, and the clamping effect is better.
Further, the inner walls of the first clamping member 131 and the second clamping member 132 are convexly provided with anti-slip patterns 134. Specifically, in the present embodiment, the inner walls of the first clamping member 131 and the second clamping member 132 are provided with protruding portions extending in the longitudinal direction from the inner walls of the first clamping member 131 and the second clamping member 132 to be wavy, and it is easy to understand that the anti-slip patterns 134 can prevent the axle box 21 from being separated when the clamping assembly 13 clamps the axle box 21.
In an embodiment, the motor car axle box disassembling device 10 further comprises a guide rail 17, the length direction of the guide rail 17 is parallel to the length direction of the motor car track, a lifting machine 18 is slidably connected to the guide rail 17, the lifting machine 18 is connected with lifting of a vertical lifting square tube 181, the lifting machine 18 is used for controlling lifting of the vertical lifting square tube 181, and one end, away from the lifting machine 18, of the vertical lifting square tube 181 is connected with the fixing frame 11. It is easy to understand that a plurality of bogies 20 are provided on a motor car, the bogies 20 are arranged along the length direction of the motor car, namely, after the motor car is stopped, the axle boxes 21 of the bogies 20 need to be disassembled along the length direction of the rail of the motor car, the bogies slide on the guide rails 17 through the elevator 18, and then the fixing frame 11 under the elevator 18 is driven to move on the rail of the motor car, so that the axle boxes 21 on the bogies 20 are disassembled, and meanwhile, the elevator 18 controls the fixing frame 11 to lift through the vertical lifting square pipe 181, so that the lifted axle boxes 21 can move to reach the maintenance point.
Further, two guide rails 17 are provided, the two guide rails 17 correspond to two rail tracks on the ground, a transverse rail 171 is provided between the two guide rails 17, and the elevator 18 reciprocates between the two rail tracks through the transverse rail 171. That is, the elevator 18 can move from one rail to the other rail through the transverse rail 171 between the two rails 17, so that the axle boxes 21 on the bogies 20 on both sides of the rail can be detached to complete the detachment of the axle boxes 21 for the whole vehicle.
Further, a rotating shaft motor 19 is disposed at one end of the vertical lifting square tube 181, which is far away from the elevator 18, and the vertical lifting square tube 181 and the fixing frame 11 horizontally rotate through the rotating shaft motor 19. It can be understood that when the axle box 21 is disassembled, one surface of the rotating base plate 12, on which the clamping assembly 13 is mounted, is opposite to the motor car bogie 20, so as to disassemble the axle box 21, and when the elevator 18 moves to the other track through the transverse rail 171, one surface of the rotating base plate 12, on which the clamping assembly 13 is mounted, is opposite to the motor car bogie on the other side, and the rotating base plate 12, on which the clamping assembly 13 is mounted, is opposite to the motor car bogie on the other side, so as to disassemble the axle box 21.
In one embodiment, the output end of the breaking cylinder 16 is wrapped with a rubber head 161. It can be appreciated that, since the rubber head 161 has elasticity, when the output end of the breaking cylinder 16 contacts with the shaft lever of the bogie 20, the damage to the shaft lever of the bogie 20 due to the overlarge contact force can be avoided, and meanwhile, the rubber material has good wear resistance, and the long-term use of the output end of the breaking cylinder 16 can be satisfied.
In an embodiment, the fixing frame 11 is provided with an operation panel 111, the operation panel 111 is electrically connected with the clamping cylinder 133, the movable cylinder 14, the overturning cylinder 15, the breaking cylinder 16, the elevator 18, the rotating shaft motor 19 and the rotating cylinder 122, and the operation panel 111 is correspondingly provided with a button 112. Specifically, an operator may control the motion of the wheel-to-axle box disassembly apparatus 10 through the operator panel 111.
