Description

Hydraulic walking type advance support equipment
Technical field
The utility model belongs to Coal Production equipment, and the spy relates to a kind of hydraulic walking type supporting equipment that is used for Coal Production development machine work plane fully.
Background technology
Along with the construction of highly efficient and productive mine, how effectively to shorten the non-cutting time that pick tunnel bolting with wire mesh is combined in the colliery, improve boring head safety guarantee coefficient, be a puzzlement coal production difficult problem for many years.The roof fall accident overwhelming majority of heading end is (accounts for sum 72%) of taking place under the situation of empty top operation, its main cause is that heading end still lacks effective temporary lining means and equipment so far in the colliery of China, have to make pick anchor operation alternately frequent, have a strong impact on drivage efficiency, and make the workman under the condition of empty top, carry out main operation, as coaling, perforating, supporting etc., very easily cause the roof fall casualty accident.The comprehensive pick tunnel of bolt support is carried out by China at present, because roadway surrounding rock mostly is medium stable and unstable situation, top board is broken, and support form is multiple combined supporting.Because of drift section is little, the supporting facility are equipped with pneumatic monomer jumbolter mostly in combining the pick construction tunnel, creep into that usefulness is low, to take non-cutting time long.Because pick anchor speed is slow, for avoiding empty top time length to cause the top board sedimentation and being out of shape and all adopting temporary lining.
For example the patent No. is No. 03220384.5, patent name for the utility model patent document of " machine-carried type coal mine roadway temporary support device " discloses a kind of driving speed with raising machine pick tunnel, alleviate labor strength, machine-carried type coal mine roadway temporary support device that the temporary lining area is big, but there is following defective in this device: the pedestal of this device is installed in development machine cabinet top, increased the height of development machine relatively, make development machine when limited lane space actual job, influence the sight line of development machine operating personnel when excavation operation; The maximum length of this device is greater than 6 meters, and this device is only applicable to that Tunnel Pressure is little, the little digging laneway of empty top, tunnel deflection.And be not suitable for that the frangible fragmentation of top board and pressure are big, unsupported back span is from not surpassing 2 meters digging laneway.
For example the patent No. is ZL200820077714.2 number, patent name is compared with the machine-carried type temporary support device for the utility model patent document of " driving face temporary lining " discloses interim this device of a kind of employing work plane, simple in structure, can be in tunneling process the immediate support top board, eliminate the operation of empty top, guarantee the safety in production of driving face, realize the multiple operation parallel operations.But there is following defective in this device: this device owing to have only main support to carry out support action, must carry out anchoring work by the workman behind work step of the every driving of development machine, holding time is long, does not improve drivage efficiency, can not realize the many anchors of a pick; Behind work step of development machine driving, must there be certain danger in the poor operability of this device by artificial laying anchor net; If when base plate is rugged and rough, this scheme does not have the base plate cleaning plant, its operability and poor stability.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provide a kind of rational in infrastructure, simple, can eliminate the operation of empty top, improve the hydraulic walking type advance support equipment of driving production efficiency.
The technical scheme that the utility model technical solution problem adopts is: hydraulic walking type advance support equipment comprises hydraulic elevating platform, pumping plant, hanger, cleaning blade, column group one, two, be characterized in column group one in per two symmetries of number row, two tops connect crossbeam group one with hinged ball, crossbeam group two, crossbeam group one is provided with at interval with crossbeam group two, in crossbeam group one, two tops are connected longeron group one with the longeron Connection Block with set bolt by the crossbeam Connection Block, two, in longeron group one, two tops are provided with several snubbers of being made up of oil cylinder and cushion block pallet, the oil cylinder of every group of snubber is communicated with, in column group one, two tops are provided with the supporting oil cylinder, hinged mount pad is established in crossbeam side above the supporting oil cylinder, adorning on hinged mount pad advances passes an end of hydraulic jack, the tailpiece of the piston rod of passing hydraulic jack of advancing is fixed on adjacent row's the hinged mount pad of crossbeam side, the passing hydraulic jack that advances is interval with two rows, on the end floor beam group two bracing frame is being housed behind the support apparatus, bracing frame lower end dress anchor net volume axle, dress anchor net volume on the anchor net volume axle, in the both sides of crossbeam group two the backstop plate is housed, in column group one, articulated linkage in the middle of being equipped with respectively on two, the two ends of connecting rod are contained in column group one with jointed shaft, in the connecting rod holder on two, in column group one, two lower end connects the bottom piston shoes with hinged ball pivot, fixation side support hydraulic pressure oil cylinder one end on two heel post groups one of support apparatus front end, the side support hydraulic pressure oil cylinder other end is contained on the fixed head, hinge connects between fixed head one end and the bottom piston shoes, the fixed head other end and cleaning blade adopt and are slidingly connected, cleaning blade connects the cleaning hydraulic jack, and the cleaning hydraulic jack is fixed on above the fixed head.
The beneficial effects of the utility model are: the employing hydraulic walking type is advanced, the method for combined knitting network structure; solve coal mine working in the past and be subjected to unsupported back span restriction allowable and situation that can only one or two picks, one anchor; the many anchors of a pick have been realized; promptly tunnel a few row's anchor poles of anchoring simultaneously after a plurality of operations; improve drivage efficiency greatly, and provide safeguard protection for workman's operation.According to working condition, withdraw from development machine after can tunneling a plurality of operations, at a few row's anchor poles of district's anchoring simultaneously of meeting head on; When operating mode allows, can lay the advance support system up to the driving tail, the workman can improve the safety and the convenience of anchoring operation greatly in the while operation of tail place, the more important thing is, makes underworkings headwork efficient no longer be subjected to pining down of anchoring operation.Advance support system top-support adopts the combined knitting network structure, promptly is when support system moves, and stent support is also arranged all the time at the top, tunnel, and top board is stressed evenly constant all the time, has increased roof stability.Equipment is provided with hydraulic elevating platform, makes things convenient for workman's operation.Carry anchor net laying apparatus, can in the system migration process, lay automatically, reduce manually-operated and labour intensity.When unexpected inbreak appearred in top board, the supporting equipment can unload, the protection entire equipment.
