Abstract
The utility model belongs to mine exploration devices, and in particular relates to a pulling type supporting frame system. The system comprises a telescopic top board oil cylinder (4), a pulling supporting frame supporting oil cylinder (5), a telescopic beam (3) and pulling supporting frame top plates (6), wherein a supporting column nest is arranged under a front supporting beam (1), a front supporting beam supporting column (2) is movably installed in the supporting post nest, the telescopic beam (3) is arranged in front of the front supporting frame (1), a plurality of pulling supporting frame top plates (6) are arranged on the telescopic beam (3) with equal distance, the telescopic top plate oil cylinder (4) and slideways (10) are fixedly installed on the lower portion among the pulling supporting frame top plates (6), and two lateral adjusting oil cylinders (7) are fixedly installed on the front portion and the rear portion of one lateral face under the supporting frame top plates (6). The pulling type supporting frame system is flexible connection among frames, the supporting frame system is stable and reliable, and the system is applicable to various working conditions with big dip angles and thin coal layers.
Description
Technical field
The utility model belongs to coal mining equipment, particularly a kind of cribbing system that pulls.
Background technology
Cantilever support is based on the support apparatus between comprehensive mining hydraulic bracket and the hydraulic prop, and existing cantilever support adopts the joist structure, holds up top board, after the front standing pillar off-load, move forward along crossheading, realize taking a step forward, when waiting to arrive assigned address, pillar stretches out, support, pull out hydraulic cylinder simultaneously, then, the back prop off-load, the hydraulic cylinder retraction, move back prop to assigned address forward, support again, finish whole moving process, but existing structure is in the coal seam of high inclination-angle, because the lateral force between frame is gathered, and has the support instability, joist stress is concentrated, connect tensile phenomenon, have the joist structure in addition, increase support height, be not suitable for the thin seam mining supporting.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of and is applicable under the complex geological conditions such as girdle and high inclination-angle, makes the stable cribbing system that pulls of support.
The technical scheme that the utility model technical solution problem adopts is: pull the cribbing system and comprise flexible top board oil cylinder, pull the stent support oil cylinder, extensible canopy, pull rack plate, be characterized in below preceding brace summer, being provided with a needling, brace summer pillar before in a needling, being equipped with versatilely, extensible canopy is established in front at preceding brace summer, above extensible canopy, all pull rack plate apart from establishing several, below pulling the rack plate centre, flexible top board oil cylinder and slideway are housed fixedly, the oil cylinder piston rod end is fixedlyed connected with preceding brace summer, flexible top board oil cylinder drives and pulls rack plate front and back slip on extensible canopy and slideway, adorn slide block in the slideway, slide block connects the location with junction plate, fixedly adorn two lateral adjustment oil cylinders before and after on a side below the rack plate, respectively adorn two below the rear and front end of rack plate and pull the stent support oil cylinder and the piston shoes pillar that is rigidly connected pulling, piston shoes pillar lower end is installed in the piston shoes.
The beneficial effects of the utility model are: pull the cribbing system and flexibly connect between a kind of, mounting system is reliable and stable, but the cantilever support with hitch structure of supporting girdle is applicable to high inclination-angle, the various working conditions of girdle.

Among the figure, brace summer before the 1-; Brace summer pillar before the 2-; The 3-extensible canopy; The 4-top board oil cylinder that stretches; 5-pulls the stent support oil cylinder; 6-pulls rack plate; 7-lateral adjustment oil cylinder; The 8-piston shoes; 9-piston shoes pillar; The 10-slideway; The 10-1-slide block; 10-1-slide block junction plate;
The specific embodiment
Embodiment, with reference to accompanying drawing 1,2, the below, preceding brace summer 1 two ends that pulls the cribbing system is provided with a needling, adorns two preceding brace summer pillars 2 versatilely in a needling.Front end at preceding brace summer 1 is adorned extensible canopy 3 versatilely, but move extensible canopy 3 upper and lower, left and right.Brace summer 1 front all pulls rack plate 6 apart from establishing five before above extensible canopy 3, the flexible top board oil cylinder 4 of dress in the middle of top board 6 belows, before being fixed on, the piston rod end of oil cylinder 4 on the front end face of brace summer 1, pulls rack plate 6 in front and back slip on extensible canopy 3 and slideway 10 under the drive that pulls top board oil cylinder 4.Slideway 10 is located at adjacent two respectively and pulls below the rack plate 6, establishes slide block 10-1 in the slideway 10, and slide block 10-1 connects the location with junction plate 10-2.Pull rack plate 6 below fix two lateral adjustment oil cylinders 7 before and after on side.Respectively adorn two before and after below top board 6 and pull the stent support oil cylinder 5 and the piston shoes pillar 9 that is rigidly connected, piston shoes pillar 9 lower ends are fixed in the middle of the piston shoes 8, and piston shoes 8 middle dress piston shoes pillars 9 play supplemental support and pull rack plate 6.
The operating principle that pulls the cribbing system is: five pull top board oil cylinder 4 and move simultaneously, protruding, brace summer 1 stretches out before driving, preceding brace summer 1 drives extensible canopy 3 and stretches out, form support space, after treating that a support has been adopted, support cylinder 5 off-loads simultaneously pull rack plate 6 and descend before and after it, and piston shoes 8 and piston shoes pillar 9 also contact with ground and play a supporting role with pulling rack plate 6.Top board oil cylinder 4 retractions, piston shoes 8 move forward with towing bracket top board 6 and pillar 9 as the strong point, pull stent support oil cylinder 5 when waiting to reach assigned address and stretch out, and jack-up pulls rack plate 6 and finishes the whole process that pulls.
Claims (2)
1. one kind pulls the cribbing system, comprise flexible top board oil cylinder (4), pull stent support oil cylinder (5), extensible canopy (3), pull rack plate (6), it is characterized in that below preceding brace summer (1), being provided with a needling, brace summer pillar (2) before in a needling, being equipped with versatilely, establish extensible canopy (3) in the front of preceding brace summer (1), top at extensible canopy (3) all pulls rack plate (6) apart from establishing several, flexible top board oil cylinder (4) of dress and slideway (10) are fixed in the below in the middle of pulling rack plate (6), the tailpiece of the piston rod of oil cylinder (4) is fixedlyed connected with preceding brace summer (1), before and after on the side of the below of rack plate (6), fixedly adorn two lateral adjustment oil cylinders (7), respectively adorn two in rear and front end, rack plate (6) below and pull stent support oil cylinder (5) and the piston shoes pillar (9) that is rigidly connected, piston shoes pillar (9) lower end is installed in the piston shoes (8).
