In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a brake drum psammitolite grabbing device which characterized in that: including bottom plate, tongs, deflector and handle, the outer circumference equipartition of bottom plate has the position sleeve, the tongs is installed through the pivot that penetrates to the position sleeve, the tongs lower part is provided with the grabhook, tongs upper portion is provided with the traveller, the traveller of tongs and the obtuse angle relation of grabhook are personally submitted in the working plane of evagination, the traveller is installed in the slide hole of deflector, the deflector middle part is connected with the handle.

Further optimize this technical scheme, the middle part of bottom plate is provided with the pull rod, the top of pull rod is connected with the handle, the pull rod penetrates in the sleeve.

Further optimize this technical scheme, the gripper working face is provided with the slipmat.

Further optimize this technical scheme, the inside and the bottom plate lower surface of gripper are connected with the spring board.

Further optimize this technical scheme, tongs, position sleeve and corresponding slide opening be provided with three groups.

Compared with the prior art, the utility model has the advantages of it is following: 1. the sliding column penetrates into the sliding hole through the gripper, the gripper can rotate around the rotating shaft, clamping of the gripper can be achieved only by pulling the lifting handle, the sand core is lifted, labor intensity is low, and required working space is small. 2. Through three groups of arranged grippers, the stress of the sand core is more balanced when the sand core of the brake drum is grabbed, and the grabbing is more reliable.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: referring to fig. 1-2, a brake drum sand core grabbing device comprises a base plate 1, a hand grip 3, a guide plate 2 and a lifting handle 202, three groups of positioning sleeves 103 are uniformly distributed on the outer circumference of the base plate 1, the hand grip 3 is installed on the positioning sleeves 103 through a penetrating rotating shaft 302, a grabbing claw 303 is arranged on the lower portion of the hand grip 3, an anti-slip pad 304 is arranged on the working surface of the grabbing claw 303, a sliding column 301 is arranged on the upper portion of the grabbing hand 3, the working planes of the sliding column 301 and the grabbing claw 303 of the hand grip 3 are in a convex obtuse angle relation, the sliding column 301 is installed in a sliding hole 203 of the guide plate 2, and the upper surface of the middle of the guide plate 2 is. The middle part of the bottom plate 1 is provided with a pull rod 101, the top of the pull rod 101 is connected with a handle 102, and the pull rod 101 penetrates into a sleeve 201. The inner side of the gripper 303 and the lower surface of the bottom plate 1 are connected with a spring plate 4.
