Description
Technical field
The utility model relates to a kind of hydraulic device of drawing sword, especially a kind of hydraulic devices of drawing sword for slotter cutter head.
Background technique
Ultra-deep underground continuous wall, which is that current deep-foundation pit engineering is optimal, goes along with sb. to guard him form, and the key equipment of its construction is exactly
Slotter.The ability that slotter can directly cut hard rock directly cuts the concrete of grooving section, is not using locking notch pipe, connector
The underground continuous wall connector that sealing is good, fine and close is formed in the case where case, but the concrete that cutting has been hardened necessarily will cause
The abrasion of milling wheel cutter head, according to one width ultra-deep of execution conditions the construction of wall second phase slot section may need replacing 100 or more
Cutter head.Since cutter head is to be fixed on milling wheel by welding, traditional bit replacing mode, which mainly uses, gets angry
Cutting, not only cutting operation is cumbersome, but also dangerous source, needs to handle fire permit.It can be simple using the utility model
Ground completes cutter head and replaces operation, and will not consume resource, operates very easy.
Summary of the invention
The utility model is the cumbersome problem of slotter cutter head replacing process to be solved, and it is dedicated to provide a kind of slotter cutter head
Hydraulic device of drawing sword.
To achieve the above object, the utility model is achieved through the following technical solutions: a kind of slotter cutter head is dedicated
Hydraulic device of drawing sword, by cutter head fixation hole, thick steel plate, separating jack, pressurizing valve, reaction frame, handle and mating oil cylinder group
At the reaction frame is in concave shape, and reaction frame middle position is equipped with a pair of of thick steel plate, is provided with fixation hole at the top of thick steel plate；Institute
It states thick steel plate two sides and is symmetrically installed separating jack, the reaction frame back side is equipped with handle.
Further, two separating jacks are same specification, product, and specification is greater than 5t.
Further, it is connected, is made in pressure process by triple valve between the mating oil cylinder and two separating jacks
Two separating jacks generate equal pressure.
Further, the thickness of the reaction frame and thick steel plate is greater than 15mm.
Further, the size of the fixation hole is adapted with fixed slotter cutter head.
The beneficial effects of the utility model are:
The utility model can improve slotter field maintenance efficiency, while slotter cutter head being avoided to make in cutting process
At damage, improve recycling rate of waterused；The utility model execute-in-place is easy, and relevant device, material are readily transported and store, and fits
Answering property is high；Practice result proof is substantially saved in the replacing construction and replacement process of slotter cutter head using the utility model
The consumption of human and material resources.
Detailed description of the invention
Fig. 1 is that the slotter cutter head dedicated hydraulic of the utility model is drawn sword device structure schematic side view；
Fig. 2 is that the slotter cutter head dedicated hydraulic of the utility model is drawn sword device structure schematic top plan view.
Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
As shown in figures 1 and 2, a kind of slotter cutter head dedicated hydraulic is drawn sword device, by cutter head fixation hole 1, thick steel plate 2, separate type
Jack 3, pressurizing valve 4, reaction frame 5, handle 6 and mating oil cylinder composition；Reaction frame 5 is that thickness is more than 15mm steel plate, in recessed
Font, reaction frame middle position are a pair of of thick steel plate 2, are provided with fixation hole 1 at the top of thick steel plate 2.2 two sides of thick steel plate are symmetrically installed
Separating jack 3, two separating jacks 3 should be same specification, same model；5 back side of reaction frame is equipped with handle 6.It removes
The outer the utility model of above-mentioned component further includes the oil cylinder and triple valve to pressurize.Oil cylinder is very heavy by triple valve connection separate type
Top 3.
Two separating jacks 3 are same specification, product, and specification is greater than 5t.Mating oil cylinder and two separate types
It is connected between jack 3 by triple valve, two separating jacks 3 in pressure process is made to generate equal pressure.Reaction frame 5
It is greater than 15mm with the thickness of thick steel plate 2.The size of fixation hole 1 is adapted with fixed slotter cutter head.
The concrete application process of the utility model are as follows:
1) device of drawing sword is installed
Slotter cutter head to be removed is fixed in cutter head fixation hole 1 by way of being embedded in reinforcing bar, adjusts hydraulic draw
Knife device position, makes separating jack 3 perpendicular to milling wheel tangent line.Draw sword at this time pulling force that device acts on cutter head perpendicular to cutter head with
Weld seam between milling wheel most effective can will be pulled out from milling wheel when head, while can be to avoid caused by because of uneven stress
Pull out situation not in place.It is adjusted in place defensive position handle 6 and fixes and slightly pressurize while drawing sword device, make separate type thousand
Jin top 3 resists milling wheel, plays the role of fixed device position of drawing sword.
2) pressurization pulls
It is pressurizeed using oil cylinder, enables two separating jacks 3 to generate equal-sized pressure by triple valve,
Pressure process should remain a constant speed as far as possible.A people is pressurizeed by oil cylinder in pressure process, and another manpower helps device of drawing sword to avoid it
It is fallen after cutter head removal, general pressure process continued for more than 10 seconds, and entirely the process of drawing sword can be completed within the time of half a minute.
3) new cutter head is installed
After pulling out old cutter head using the utility model, milling wheel surface is more cleaned, can be upper without carrying out specially treated
Rheme sets the new cutter head of welding.
