Description
Technical field
The technical field of the comprehensive pick face gib of underground coal mine is the utility model is related to, specifically a kind of New Coal Mine tunnel
Comprehensive pick face temporary support device.
Background technology
Before the development of speedy drivage temporary shoring bracket, what most domestic underground coal mine driving face generally used faces
When supporting have：First, hanging ring tube-through type forestope gib；Second, vehicle-mounted temporary support device for development machine；Third, using more
Row's hydraulic prop increases intensity I-steel capplce method of support etc..Although these modes alleviate heading driver to a certain extent
Met head on as face the pressure of supporting, improve the supporting situation of working face, but also there is many deficiencies in actual use
Locate, larger hidden danger is still had in safety.The safety problem of temporary support for drivage face is that long-standing problem colliery is quickly dug
Enter the technical barrier of safety in production for many years, because top plate can not obtain effective supporting in time after tunnelling, often cause
Top plate falls cash casualty accident, can not give full play to the efficiency of high-performance development machine.
（1）Hanging ring tube-through type forestope gib
Hanging ring wears formula forestope gib, is mainly made up of hanging ring and forestope, ring is fixed on top plate by anchor pole
On, forestope leans out rear supporting roof in suspension ring, its subject matter：1. steel and top plate are stopped in fact using half round timber and timber wedge
The back of the body is tight, without setting load, great potential safety hazard be present；2. forestope is point or linear contact lay with top plate, it is impossible to complete to empty top zone
Face carries out effective support, worse if running into roof cracking using effect；3. operating process is complicated, it is necessary to manually move, work
Intensity is big, and gib speed is slow, efficiency is low；4. bolting with wire mesh mode operator in lapping has to enter into empty top zone operation,
In the presence of great potential safety hazard.
（2）Vehicle-mounted temporary support device for development machine
Device is mainly made up of left and right base, left and right frame, left and right rollover stand, left and right folding arm frame and upper frame beam, is arranged on
Development machine front middle part.When development machine normally tunnels, the folding device is contracted in cut reductor back, does not disturb the fortune of development machine
Dynamic and cut operation function；Need to control the position of folding stand by operating the hydraulic control valve of supporting folding stand during supporting,
Stretch out folding stand and be supported in top plate, complete branch protective function.Its major defect：1. supporting area is small, it is impossible to complete supporting exposure
Top plate;2. during bolting with wire mesh, there is great potential safety hazard in operating personnel's still operation in the case where sky pushes up;3. the device is to top plate
Bad adaptability.Roof and floor fluctuating is run into during driving, tunnel step-down, airborne supporting can not completely put to good use open, not reach setting load, deposit
In larger potential safety hazard.
（3）Multiple rows of hydraulic prop increases intensity I-steel capplce method of support
First then tapped again rapidly using hydraulic single prop by empty top zone firm supporting after machine pick, wait to locate
After having managed cash living, float stone, rapidly with monomer column by I-steel and steel wire top to top straight portion, networking, protect top plate.
At least three people, which coordinate, when installing every hydraulic prop carries out gib, and labor strength is big, and cost is high, and prop drawing is dangerous
Property is big, potential safety hazard be present, and influences personnel and equipment is passed through, and supporting effect and safety guarantee are undesirable.
