Description
Technical field
Toothing and hydraulic shear are cut the utility model is related to a kind of hydraulic shear, belongs to technical field of engineering machinery.
Background technology
During demolishing buildings, hydraulic shear is widely used as one of forcible entry rescue tool, can by hydraulic shear
Operation is sheared or shredded to the concrete wall of building, reinforcing bar etc., realizes the purpose of demolition of buildings or rescue.
In dismantling concrete wall, initial stage is removed, wall block is larger, and the existing left and right tooth of cutting of more hydraulic shear is adopted
Cut tooth with c-type, it is left and right cut tooth pairing after gap can clamp larger wall block greatly, 98 still treat that wall is broken into fritter by bulk
Afterwards, since the left and right gap cut after tooth pairing is big, small block concrete can not be clamped, small block concrete can not be continued to shred work
Industry, therefore need replacing hydraulic shear is replaced and cuts the small hydraulic shear in gap after tooth pairing with zigzag, could continue concrete wall
Comminution process, and for carrying the concrete wall of reinforcing bar, once concrete wall is cut the hydraulic shear shearing work of tooth by c-type
, it is necessary to carry out shear treatment to reinforcing bar after exposing reinforcing bar, and the hydraulic shear that c-type cuts tooth can not complete bar cutting operation, therefore also
The hydraulic shear of bar cutting operation can be realized by needing replacing into, existing hydraulic shear to cut tooth relatively simple, cause entirely to remove
Operation needs repeatedly to replace hydraulic shear, and not only dismounting efficiency is low, and if cannot replace damage hydraulic shear in time while influence to tear open
Except quality.
Utility model content
The utility model is in view of the deficienciess of the prior art, offer one kind, without repeatedly replacing, is torn open there are many shear blade
Toothing and hydraulic shear are cut except efficient hydraulic shear.
The technical solution that the utility model solves above-mentioned technical problem is as follows：A kind of hydraulic shear cuts toothing, including by
Being cut for the first jaw of small concrete walls block shearing work, for big concrete walls block on cutter hub is successively set on after going to
The second jaw and the spliced body for bar cutting operation for cutting operation, the cutting edge of first jaw are laciniation, institute
The cutting edge of the second jaw is stated as wavelike structure, the cutting edge of the spliced body is straight type cutting edge.
The beneficial effects of the utility model are：When removing building, the second pincers can be used in dismantling concrete wall at the beginning
Mouth carries out shearing work, makes full use of the shear blade of wavelike structure, and when running into reinforcing bar, shear action is carried out using spliced body
Reinforcing bar can be interrupted in time, for by the second jaw shearing after concrete walls block can further be sheared by the first jaw by
It is shredded.The utility model structure letter is answered, easy to operate, can remove architectural process shearing concrete wall and reinforcing bar, for
Concrete fritter after shearing can also be shredded further, and entire demolishing process more can guarantee that dismounting is built without repeatedly replacing
The efficiency built.
Based on the above technical solutions, the utility model can also do following improvement.
Further, the spliced body is mounted on cutting edge mounting base by bolt, and the cutting edge mounting base is equipped with and is used for
The groove of spliced body is installed, the cutting edge mounting base is fixedly connected with the cutter hub.
Advantageous effect using above-mentioned further scheme is that the abrasion of operation shear blade is severe to be needed often since reinforcing bar is cut
It replaces, therefore spliced body but is installed not with cutter hub integral structure by mounting base, it is accurate that groove can carry out shear blade
Positioning.
Further, the spliced body protrudes from the outer profile of the cutting edge mounting base.
Advantageous effect using above-mentioned further scheme is to cut reinforcing bar convenient for spliced body, while cutting edge protrudes from installation
Seat avoids shearing work process from damaging cutting edge mounting base.
Further, the spliced body is by locking knife bolt in the groove of the cutting edge mounting base.
Advantageous effect using above-mentioned further scheme is that shear blade is easy for installation, is conveniently replaceable after damage.
Further, the cutter hub is equipped with the hinged axis hole for being used for cutter hub rotation and the oil for being connected with driving mechanism
Cylinder shaft hole.
Advantageous effect using above-mentioned further scheme is to facilitate driving cutter hub action.
The utility model further relates to a kind of hydraulic shear, described left and right to cut including symmetrically arranged left shear body and right shear body
Body is respectively adopted cuts toothing as described above.
The beneficial effects of the utility model are：Two scissor bodies of hydraulic shear all cut toothing, hydraulic shear knot using above-mentioned
Structure is compact, easy for installation, and dismounting is efficient, removes quality more preferably.

Specific embodiment
The principle and feature of the utility model are described below in conjunction with example, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As Figure 1-Figure 5, a kind of hydraulic shear cuts toothing, is used on cutter hub including being successively set on from front to back
First jaw 1 of small concrete walls block shearing work, for the second jaw 2 of big concrete walls block shearing work and for reinforcing bar
The spliced body 3 of shearing work, the cutting edge of first jaw is laciniation, and the cutting edge of second jaw is wavy knot
Structure, the cutting edge of the spliced body is straight type cutting edge.First jaw, the second jaw and cutter hub integral structure.
The spliced body is mounted on cutting edge mounting base 4 by bolt, and the cutting edge mounting base is equipped with to install shearing
The groove 5 of body, the cutting edge mounting base are fixedly connected with the cutter hub.Since reinforcing bar is cut, the abrasion of operation shear blade is severe to be needed
It often replaces, therefore spliced body but is installed, groove can carry out shear blade not with cutter hub integral structure by mounting base
It is accurately positioned.
The cutting edge of the spliced body protrudes from the outer profile of the cutting edge mounting base.Reinforcing bar is cut convenient for spliced body, simultaneously
Cutting edge protrudes from mounting base and shearing work process is avoided to damage cutting edge mounting base.
The spliced body is by locking knife bolt 6 in the groove of the cutting edge mounting base.Shear blade is easy for installation, damage
It is conveniently replaceable after bad.
The cutter hub 9 is equipped with for the hinged axis hole 7 of cutter hub rotation and the oil cylinder axis hole for being connected with driving mechanism
8.Facilitate driving cutter hub action.
As shown in fig. 6, the utility model further relates to a kind of hydraulic shear, including symmetrically arranged left shear body 10 and right shear body
11, the left and right shear body is respectively adopted cuts toothing as described above.Two scissor bodies of hydraulic shear all cut tooth knot using above-mentioned
Structure, hydraulic shear is compact-sized, easy for installation, and dismounting is efficient, removes quality more preferably.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within new spirit and principle, any modifications, equivalent replacements and improvements are made should be included in the guarantor of the utility model
Within the scope of shield.
