Description
Technical field
The utility model relates to a kind of chuck assembly, especially relates to a kind of hydraulic pressure lasso formula chuck with axial float that can realize a kind of raise boring machine of Fully-mechanized upraise.
Background technology
At present; Domestic mine has begun to promote this Fully-mechanized upraise method of raise boring machine; Chuck is the drilling rod clamping device of raise boring machine; It couples together drilling rod and reduction box, passes to drilling rod to the required axial compression of fractured rock and rotary torque and cooling drilling tool with the required cooling water of dirt that goes out; It can be when unloading drilling rod the clamping drilling rod, unload the connecting thread between the loose drilling rod; It creeps into precision in raising, and aspects such as increase rig life-span play crucial effect.Domestic existing raise boring machine once adopted the fast formula chuck of a kind of manual wedge-shaped card; It is that manual work is squeezed into fixture block with hand hammer, utilizes the wedging power on fixture block inclined-plane to block drilling rod, and this chuck structure is simple; But labor strength is big; It is slow to unload bar speed, and axial float mechanism is not set, on damage drill rod thread when unloading drilling rod easily.Also there is not hydraulic pressure lasso formula chuck in the prior art.
The utility model content
The purpose of the utility model is to provide a kind of hydraulic pressure lasso formula chuck with axial float of raise boring machine.With realize improving greatly mechanization degree and easy and simple to handle, long service life, compact conformation, appearance and size is little.
The technological technical scheme of the utility model is: around chuck body, shipping and reselling on another market through claw is hinged with four claws, and four fixture blocks and claw are fixed as one; On chuck body, be provided with and make the outside open spring of claw, chuck cover movingly is housed outside chuck body; Between chuck body top and chuck tooth embedding cover plate, be provided with the end play that forms axial float mechanism; Chuck tooth embedding cover plate and ratchet are fixed as one; The inner spline gear fit of the spline tooth on chuck body top and ratchet; Be provided with the main shaft king-bolt that the reduction box main shaft with raise boring machine spins in chuck body upper end, the chuck body bottom is provided with the taper thread hole of jointed rod; Chuck tooth embedding cover plate is provided with 2-3 lubricating cup that is communicated with chuck body; The lower end of the chuck oil cylinder on the chuck cylinder bracket is hinged on the shift fork end; Be provided with the shift fork idler wheel mechanism in shift fork left end both sides.
Said shift fork idler wheel mechanism is made up of roller shaft, roller, needle bearing and nut; Idler wheel mechanism is inserted in the cannelure of chuck cover, the chuck cover is lifted, and with the rotation of chuck friction rolling.
The outer rim of said chuck tooth embedding cover plate and ratchet is provided with the location hoop.Play the radial location effect, guarantee with one heart.
The nut cylindrical that said chuck body top inner headed face is provided with the main shaft king-bolt is sealing ring movingly.Can guarantee to carry the cooling water that gets off not leak from reduction box main shaft mesopore.
Said chuck jar support is through on the reduction box base plate that is bolted to raise boring machine.
When the chuck cylinder moved upward, shift fork promoted the chuck cover and moves downward, and the inclined-plane that chuck puts setting forces four claws to draw in, makes card block the square bayonet socket of drilling rod soon.
When the chuck cylinder was descending, the chuck cover rose, and claw opens under spring action, and fixture block breaks away from the bayonet socket of drilling rod.
During connecting and disconnecting drill rod (drill rod thread promptly spins); Chuck body can be in ratchet free axial float; Amount of floating is L, to remedy owing to the asynchronous displacement difference that produces with forward displacement speed of the velocity of displacement that spins, the issuable axial additional force of the drilling rod of avoiding spinning; Protect drill rod thread effectively, improved the application life of drilling rod.
The utility model mechanization degree is high, and easy and simple to handle, clamping speed is fast, can effectively reduce subsidiary operation time; And compact conformation, appearance and size is little; Because chuck body can be in ratchet free axial float; Can remedy when spinning drilling rod owing to the asynchronous displacement difference that produces of the velocity of displacement that spins with forward displacement speed; The issuable axial additional force of the drilling rod of avoiding spinning has been protected drill rod thread effectively, has improved the application life of drilling rod; Bar or the remote control bar of unloading if equipped automatic program control system or remote control system can realize unloading automatically.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
With reference to accompanying drawing, present embodiment comprises parts such as main shaft king-bolt 1, chuck tooth embedding cover plate 2, sealing ring 3, lubricating cup 4, cover plate connecting bolt 5, ratchet 6, locating ring 7, chuck jar support 8, bolt 9, chuck oil cylinder 10, shift fork 11, chuck cover 12, chuck body 13, claw ship and resell on another market 14, claw 15, spring 16, fixture block 17, shift fork roller shaft 21, nut 22, roller 23;
Around chuck body 13, ship and resell on another market and 14 be hinged with 15, four fixture blocks 17 of four claws and be fixed as one through draw-in groove and screw and claw 15 through claw; The ship and resell on another market chuck body 13 of 14 belows of claw is provided with and forces the outside open spring 16 of claw, the 13 chuck covers 12 that are equipped with movingly outside chuck body; Be provided with the end play L that forms axial float mechanism between chuck body 13 tops and the chuck tooth embedding cover plate 2; Chuck tooth embedding cover plate 2 is fixed as one through cover plate connecting bolt 5 and ratchet 6; The spline tooth 19 on chuck body 13 tops and the inner spline gear fit of ratchet; Be provided with the main shaft king-bolt 1 that the reduction box main shaft with raise boring machine spins in chuck body 13 upper ends, the chuck body bottom is provided with the taper thread hole of jointed rod 19; Chuck tooth embedding cover plate 2 is provided with 2-3 lubricating cup 4 that is communicated with chuck body 13; The upper end of chuck oil cylinder 10 is hinged on the chuck cylinder bracket 8, and the lower end is hinged on the end of shift fork 11; Be hinged on the chuck cylinder bracket 8 in the middle of the shift fork 11; Shift fork 11 left end both sides are provided with the idler wheel mechanism of being made up of roller shaft 21, roller (needle bearing) 23 and nut 22; Idler wheel mechanism is inserted in the cannelure of chuck cover 12, chuck cover 12 is lifted, and do friction rolling with the rotation of chuck.
