Description

A kind of recoverable side slope anchor pole stops sizing device
Technical field
The present invention relates to a kind of side slope anchor poles to stop sizing device, and specifically a kind of recoverable side slope anchor pole stops sizing device, belongs to In slope retaining field.
Background technology
A kind of important form that suspension roof support is reinforced as geotechnical engineering, since it is with safe, inexpensive, easy for construction The advantages that, it is widely used in geotechnical engineering field, one important procedure of the slip casting as suspension roof support, at present extensively The method of use is to fill drilling from bottom hole to flow out up to from aperture, and free end and anchoring section are filled, do so not only Waste, and the transmission of anchor pole power is directly affected, to influence bolt anchorage effect.
Inventor retrieves following Patents documents:CN2714627Y discloses a kind of slurries densification ring type anchor rod and only starches Device is made of preceding grout stop, rear grout stop, packing cloth, Grouting Pipe and gunniting hole etc.;The interior plate of wherein forward and backward grout stop It is welded on anchor tie corresponding position, opens that there are two symmetrical Grouting Pipes to be inserted into hole on grout stop, be enclosed on forward and backward grout stop Packing cloth is fixed on two pieces of grout stop iron plates with rivet in the outside of packing cloth, gunniting hole is provided on first time grouting pipeline. CN2766041Y discloses a kind of rockbolt packer, because the side of rockbolt packer is axially cracked, as long as rockbolt packer is sent Enter anchor hole, rockbolt packer endoporus can become smaller after being squeezed by anchor hole, so that it may while to be easy to anchor pole being fixedly clamped, anchor pole Stop grouting plug also reliably blocks anchor hole external port, meets various bolt stress slip castings and only starches requirement.
The above technology accomplishes effectively to block anchoring section for how to make side slope anchor pole stop sizing device, and And reach better anchoring effect, do not provide specific guidance program.
Invention content
Technical problem to be solved by the present invention lies in, a kind of recoverable side slope anchor pole is provided and stops sizing device, the side slope Anchor pole stops sizing device and can effectively be blocked to anchoring section in bolt grouting, not only saves a large amount of injecting paste material, but also Better anchoring effect can be reached.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:
A kind of recoverable side slope anchor pole stops sizing device, has casing, its technical solution is that the recoverable side Slope anchor pole stop sizing device also and have be sleeved on casing can along the cannula slide sliding sleeve, be fixed on the top outer wall of casing Baffle ring, be sleeved on casing the compressed spring limited up and down by baffle ring and sliding sleeve respectively, be installed on the sliding sleeve Switching mechanism, only pulp surface, multiple skeletons, the only pulp surface is by the annular steel disc of multiple fans(Multiple sector steel discs)Distribution group in a ring It closes, the annular steel disc of two fans of arbitrary neighborhood is hinged in the multiple annular steel disc of fan(Pivot joint), each fan annular Steel disc is connected with the baffle ring, and connection structure is the annular steel disc of each fan has bending trace with baffle ring connection(Folding Trace), each annular steel disc of fan is along its corresponding bending trace(Folding line)It can bending;The multiple skeleton and multiple fans annular steel disc one One is corresponding, and one end of each skeleton is hinged with sliding sleeve, the annular steel disc of a fan of the other end of the skeleton corresponding thereto It is hinged;It is respectively provided with the gas vent of the slurry-feeding hole and connection exhaust pipe of connection Grouting Pipe in the only pulp surface, has in described sleeve pipe Having to match with the switching mechanism makes sliding sleeve be located on casing and realizes the only distracted groove of pulp surface.
In above-mentioned technical proposal, the switching mechanism is preferably provided with steel wire rope, is fixed on the lateral wall of sliding sleeve Bearing, positioned at the support outer by the fixed pulley of the bearing spacing supporting, position limit arm, the support being fixedly installed on bearing Axis, compression spring, position limit arm have in the spacer pin being laterally arranged, the rotor that can be rotated along support shaft, the lower end of the rotor It is limited by the outboard end of compression spring, the inner end of compression spring is limited by the lateral wall of sliding sleeve, and the centre position of the rotor is set to In support shaft, the upper end of the rotor is fixedly connected with the outboard end of the spacer pin, one of the inside of the spacer pin Divide in the mounting hole being inserted on the lateral wall of sliding sleeve and makes spacer pin by the mounting hole guide and limit, when in the spacer pin When side is inserted into the groove, sliding sleeve is located on casing, and one end of steel wire rope is free end, the other end of steel wire rope around It crosses fixed pulley and is fixedly connected with the upper end of the rotor.In this way, the steel wire rope by switching mechanism controls the spacer pin Positioning and non-locating of the flexible realization sliding sleeve on casing in the mounting hole(Separation), i.e., realized by switching mechanism Only pulp surface(It could also say that the annular steel disc of multiple fans)Strut or close up.
In above-mentioned technical proposal, the quantity of the slurry-feeding hole and gas vent is all one, and slurry-feeding hole and gas vent are only It is preferably symmetric in pulp surface, slurry-feeding hole and gas vent are located on the annular steel disc of two fans.The multiple annular steel disc of fan Quantity is preferably eight, and correspondingly, the quantity of multiple skeletons is also eight.
Recoverable side slope anchor pole of the present invention stops sizing device also and has that be sleeved on casing can be along the cannula slide Sliding sleeve, be fixed on the top outer wall of casing baffle ring, be sleeved on casing and limited up and down by baffle ring and sliding sleeve respectively Compressed spring, be installed on the sliding sleeve switching mechanism, only pulp surface, multiple skeletons.In this way, will be more in bolt grouting The annular steel disc expansion of a fan, forms and stops pulp surface, you can effectively to anchoring section(Anchored end)It is blocked, prevents binding material Flowing to free end optimizes the force structure of anchor pole, not only saves a large amount of injecting paste material(Binding material)And increase Add anchoring effect, closes up the only slurry dress of the i.e. recyclable present invention of the annular steel disc of fan after the completion of slip casting task by switching mechanism It sets.Through experiment, only slurry effect of the invention is good, and voltage stabilizing ability is strong, it can be ensured that grouting pressure makes anchor rod ultimate hold in 3MPa or more Loading capability improves a lot, and average increase rate saves injecting paste material 28% or more(Binding material)30% or more, close up The time of the only sizing device of the annular steel disc recycling present invention of fan was very short, at 1 ~ 2 minute.
