As shown in fig. 1, a bolt limiting mechanism comprises a base 1, a bolt 2 and a driving mechanism installed on the base 1, wherein the output end of the driving mechanism is connected to the bolt 2; a bearing guide hole is formed in the base 1 and is matched with the bolt 2, and the bolt 2 is movably connected in the bearing guide hole and extends out or retracts in the axial direction of the bearing guide hole.

The utility model provides a bolt stop gear is the retraction of living of stretching out through actuating mechanism controls bolt 2 on the one hand, has realized the automation, has overcome the defect that needs artifical plug among the prior art, can effectively reduce intensity of labour. On the other hand, when the end of the bolt 2 extends out and bears the gravity load, the middle part of the bolt 2 is still inserted into the bearing guide hole, compared with the traditional bolt taking the tail end of the bolt as the bearing fulcrum, the bolt has remarkable progress, the whole square hole is uniformly stressed, and the square hole can bear more load and cannot cause the deformation of the bolt 2.

As shown in fig. 1-2, the driving mechanism is a cylinder 4 fixed on the surface of the base 1 by screws. One end of the bolt 2 is provided with a connecting hole, and a push rod 3 is connected in the connecting hole. And the other end of the push rod 3 is provided with a threaded through hole and is fixedly connected with the output end of the driving mechanism. The connecting hole is preferably arranged in the axial vertical direction of the bolt 2, and the bolt 2 can be effectively prevented from falling off and positioned by the aid of the push rod 3. Preferably, the output end of the driving mechanism is inserted into the threaded through hole, the piston rod of the cylinder 4 can be tightly connected with the push rod 3 through a nut of the cylinder 4, and thereafter, the cylinder 4 can drive the bolt 2 to move along the axial direction of the bearing guide hole through the push rod 3.

As preferred, cylinder 4 specifically can be ultra-thin type cylinder, and ultra-thin cylinder can effectively reduce the shared volume of bolt stop gear, the installation of being convenient for.

When specifically using, according to the spacing mechanical condition of needs bolt, align installation face on the machinery with base 1, because base 1 bottom both sides expand there is the installation floor to system has a plurality of installation screw holes on the installation floor. The threaded holes are only required to be aligned to the reserved threaded holes of the mechanical mounting surface, and the screws are used for assembling, mounting and connecting, so that the mounting and the dismounting are simple on the whole.

When needs bolt 2 to carry out spacingly, 4 work gassing of cylinder, the piston is retrieved, and the piston rod drives push rod 3 and removes to 4 directions of cylinder, and in the connecting hole on bolt 2 was inserted to 3 lower parts of push rod, has driven bolt 2 to 4 directions of cylinder removal simultaneously, and at this moment, the other end of bolt 2 stretched out and bears the weight of the guiding hole, realizes limit function. The bearing guide hole is a square hole, and the size of the bolt 2 is matched with the square hole. When the end that bolt 2 stretches out bears the load, the design of square hole can make bolt 2 atress even when bearing the load, avoids warping.

When the spacing of needs is relieved, 4 work of cylinder are aerifyd, and the piston is released, and the piston rod drives push rod 3 and keeps away from 4 directions of cylinder and remove, drives bolt 2 simultaneously and removes to keeping away from 4 directions of cylinder. At the moment, the bolt 2 retracts into the bearing guide hole, and the limit is released. And the corner of the bolt 2 can be provided with a transition sliding surface, and the transition sliding surface can play a role in guiding installation and avoiding scratch.
