Description
Technical Field
The invention relates to the technical field of engineering machinery rescue equipment, in particular to a clamping claw locking mechanism applied to an open hole coring and breaking accessory.
Background
When rescue is carried out after earthquake disaster, various ruins breaking and detaching accessories can efficiently and safely open rescue channels for rescue workers, and play an important role in rescue tasks. Various inventions about rescue equipment are produced in order to complete rescue tasks under complex conditions after various disasters. The invention patent CN201610232481.8 discloses a breaking-in attachment integrating a hole-opening coring function, and the attachment can be used for quickly cutting and taking out a rectangular concrete core block on a concrete wall. However, the core holding claw cannot actively hold the concrete core block, and the holding claw deforms due to the gravity of the core block after the hole is formed, so that the problems of saw blade blocking, core block sliding and the like during core taking are caused. Aiming at the problems, the invention provides a clamping claw locking mechanism for a hole-opening coring accessory.
Disclosure of Invention
The invention aims to provide a clamping claw locking mechanism for a hole-opening coring accessory, and solves the problem that the hole-opening coring accessory disclosed in the invention patent CN201610232481.8 cannot actively clamp a core block.
The invention adopts the technical scheme that the holding claw locking mechanism for the tapping coring accessory has two working states: the core holding locking working state and the core removing working state. When the concrete core block is gripped, the core is gripped and the working state is locked; when the concrete core blocks are loosened and removed, the working state of core removal is realized.
Specifically, the holding claw locking mechanism consists of an installation base group and two locking holding claws. The locking holding claw is composed of a hydraulic cylinder, a floating base, a holding claw connecting rod, a holding claw, a sliding rail and an upper sliding sheet part. The mounting base group consists of a mounting base, a floating base shaft, a return spring and a lower sliding sheet. The floating base shaft is connected with a floating base in the locking holding claw in a sliding mode to form a first moving pair. A return spring is arranged between the floating base and the floating base shaft, and when the force between the upper slide sheet and the lower slide sheet is smaller than the elastic force of the return spring, the floating base is restored to be tightly attached to the mounting base; the holding claw is fixed with the sliding block through a sliding block bolt, a side groove of the sliding block is in sliding fit with a side protrusion of the sliding rail, the sliding rail is fixed with the floating base through a screw, a holding claw connecting rod is fixed with the holding claw 17 through a holding claw fixing bolt and is connected with a hydraulic cylinder through a fixing nut, and the hydraulic cylinder drives the holding claw to slide along the sliding rail to form a second sliding pair.
The plane locked by the holding claw and the normal plane of the mounting base group form an included angle of 15 degrees. When the working state of coring is changed to the working state of locking the core, the single locking and embracing claw is changed into 3 sliding pairs from 1 sliding pair. When the core is removed, the upper sliding sheet and the lower sliding sheet are not contacted, and the floating base is limited on the mounting base by the return spring; the single locking holding claw is only provided with 1 sliding pair of the hydraulic cylinder; when the core holding locking working state is carried out, the upper sliding piece is in contact with the lower sliding piece to form a sliding pair, the hydraulic cylinder is subjected to resistance of the upper sliding piece and the lower sliding piece, the holding claw is changed into movement along the direction of the contact surface of the upper sliding piece and the lower sliding piece along the movement of the sliding rail, meanwhile, the floating base overcomes the elasticity of the reset spring to move upwards, the holding claw is locked towards the inner side, and at the moment, the single locking holding claw has 3 moving pairs.
When the core holding lock is in a working state, the hydraulic cylinder retracts to drive the holding claw to be inserted into the cutting seam along the slide rail, and the upper slide sheet and the lower slide sheet are contacted after the hydraulic cylinder retracts for a certain distance; then, along with the continuous retraction of the hydraulic cylinder, the holding claw moves inwards along the upper scribing sheet contact surface and the lower scribing sheet contact surface, and the floating base moves upwards along the axis of the floating base, so that the distance between the holding claw and the side surface of the concrete core block is reduced, the effect of holding the concrete core block tightly by the holding claw is realized, and the locking function is realized and maintained through the thrust of the hydraulic cylinder.
When the core is removed, the hydraulic cylinder extends out to drive the holding claw to move outwards along the upper scribing contact surface and the lower scribing contact surface, so that the distance between the holding claw and the side surface of the concrete core block is increased, the effect of loosening the concrete core block by the holding claw is realized, and at the moment, the floating base moves downwards along the floating base shaft under the action of the reset spring; and when the hydraulic cylinder extends out for a certain distance, the upper sliding sheet and the lower sliding sheet are separated, and the holding claw is completely retracted.
