Description
Technical field
Hydraulic support disintegration ejector pin device, belongs to colliery support solution pin apparatus field.
Background technology
Install in colliery, withdraw in work.Owing in mine, some hydraulic support volumes are big, heavy, transported on the way
The restriction of circuit, support needs after withdrawing from first to disintegrate to dispense and could go up well.The traditional dismounting technique of hydraulic support is first by round pin
Bolt hole use mantle fiber bolt to be packaged silk, use the bolt of pulling pin of 24 or 30 to tighten, re-use pin pulling out device by it
Haul out.But owing to hydraulic support is at down-hole Long-Time Service, the connecting pin of each parts during disintegrating can be caused to be difficult to extract.Warp
The bolt that often occurs pulling pin pulls off or extracts even by situations such as connection chain pull off, and labour intensity is relatively during solving pin for operating personnel
High, safety can not get ensureing that obstruction withdraws speed simultaneously affects normal organization of production.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, security
Hydraulic support disintegration ejector pin device good, that efficiency is high, labour intensity is low.
The technical solution adopted for the present invention to solve the technical problems is: this hydraulic top pin assembly, it is characterised in that: include
The bracing frame being slidably installed in base, base and the oil cylinder being welded on bracing frame top, in the middle part of described base bottom and bracing frame
It is provided with crossbeam, is flexibly connected by Lift Part between two crossbeams；Connect equipped with corresponding support on described oil cylinder front and back sides
Part, oil cylinder connects feeding means by sebific duct.
The effect of the present invention is to provide a kind of ejector pin device for the support that mine inner volume is big, heavy, the present invention's
Base and bracing frame can be by ejector pin modular support in desired positions, when oil cylinder starts ejector pin work, and the oil supply that sebific duct connects
Device can have a certain distance from support.After this ejector pin device is connected location by stand connection with the round pin of support, work
Personnel can control ejector pin at feeding means, it might even be possible to hides oneself in the blindage arranged, it is ensured that the safety of workmen.Work
Process of making only need to be fixed ejector pin setting position and control feeding means, and labour intensity is substantially reduced, and operating efficiency obtains carrying more greatly
High.
Described Lift Part is jackscrew or hydraulic jack.
A pair pair of angular vertex of described jackscrew is respectively hinged at the middle part of crossbeam, and another of jackscrew is right
Screw thread between angular vertex is connected with rocking bar；The crank that described rocking bar is welded by threaded rod and threaded rod one end forms, threaded rod bag
Include and be provided with two parts before and after reverse thread.
Lift Part selects jackscrew of the present invention, and simple in construction is easily controllable, and lifting process is stable.The present invention
Described jackscrew utilizes rocking bar can arbitrarily regulate height, it is believed that closely control without extra power, operating process side
Just, simply, steadily.
Described stand connection includes two parts before and after adjusting rod and hook, and adjusting rod one end is hinged on oil cylinder, adjusts
The pole other end and hook socket, adjusting rod is offered multiple equidistant screw with linking up with and is fixed by bolt.The present invention adopts
By this simple stand connection, this ejector pin device is connected with the support that need to dismantle round pin location.Only need to will hang during aggressiveness operation
It is hooked on support, regulation adjusting rod and the fixing position of the upper bolt of hook, makes hook try one's best stress, control oil cylinder afterwards and stretch
Long, round pin can be ejected.The adjusting rod of both sides and hook screwhole position are certain, and length is constant, it is ensured that the center of oil cylinder and circle
The center of pin the most point-blank, prevents skew from causing danger.
Described feeding means can be selected for hand supercharging bar.Feeding means selects hand supercharging bar to meet drive environment, nothing
Additional energy source power need to be provided, it is easy to carry movement, operation easily.
Described oil cylinder enters, liquid return hole is equipped with hydraulic two-way lock.
Described base and bracing frame are all for the cube-shaped frame surrounded by four armstands and horizontal beam, and four of base stand
Forming slideway inside arm, bracing frame makes bracing frame can slide up and down in base in being slidably mounted on slideway.Its neutral arm
Material is angle steel, and the material of crossbeam is band steel.Bracing frame and base ensure lifting steadily, and the quadrangular bottom that base is formed is prone to
Obtain diagonal, determine center of gravity, it is ensured that mechanism during work is steady.Base forms slideway during bracing frame lifting, and lifting is steadily
There is provided lateral support force can also to the bracing frame on top and oil cylinder, it is ensured that the center of oil cylinder and circle all the time during oil cylinder ejector pin
The center of pin point-blank, and does not offsets.
It is ejector pin accessory that this hydraulic top pin assembly is furnished with ejector pin block, and ejector pin block is cylindrical bloom.During ejector pin, circle
After pin generation is loosening after the most cheap segment distance, pin-and-hole leaks outside, and is placed in pin-and-hole by ejector pin block, again fixes this ejector pin dress
Put, the center alignment ejector pin block of oil cylinder, utilize ejector pin block to be ejected completely by round pin again.Ejector pin block act for sb round pin position after,
Frame will not at once avalanche, and ejector pin block easily takes out.Convenient dismounting.During will not be delayed other work of pulling pin of ejector pin device
Make.
Compared with prior art, hydraulic top pin assembly the had the beneficial effect that hydraulic top pin assembly of the present invention
Application, it is ensured that the personal safety of ejector pin process, chain rupture of having stopped to pull pin, damages the phenomenon pulling out screw, improves simultaneously and pulls pin
Effect and efficiency.Coming into operation of hydraulic top pin assembly improves the personal security coefficient during support disintegrates.Reduce
Construction link, greatly reduces the labour intensity of workman.Improve efficiency, stop phenomenon of doing over again.Simple in construction, becomes
This is cheap, has social benefit and promotional value widely.
