Description
Technical field
The present invention relates to the coal mining field, the convenient lifting appliance of especially a kind of hydraulic support.
Background technology
At present; The comprehensive technical elements of adopting in the colliery, what return most critical when removing at hydraulic support is the lifting and the entrucking part of hydraulic support, this is back the emphasis and the difficult point of removing; Now; The ZY2100/11/22A type hydraulic support height that fully-mechanized mining working generally uses is 1100-2200mm, and the face height of adopting is 1550-2000mm, and will to guarantee that the support oneself height drops to before adopting the face entrucking enough low to guarantee the lifting and the normal transport of support transporting for this reason.
Colliery, Anshun with Guizhou is an example, and colliery, Anshun 9103 driving surfaces adopt the exploitation of comprehensive mechanical metallization processes.Driving surface haulage gate length 1010m, track crossheading length 925m, area 163978m2, the average mining height 1.6m of driving surface, 38.35 ten thousand tons of recoverable reserves.According to design, it is 80m that driving surface is reserved coal pillar width, and in 1, on September of back production to 2011,9103 fully-mechanized mining workings begin back to remove.The hydraulic support that 9103 fully-mechanized mining workings use in colliery, Anshun is ZY2100/11/22A type hydraulic support; The weight of each hydraulic support is 6.8t; The entrucking of hydraulic support needs earlier hydraulic support to be lifted by crane; Present lifting is toward operation, be that to be employed in lifting appliance (for example: chain block, sylvester etc.) fixing on the top board be directly to be fixed on anchor pole or the ladder beam, but the weight weight of carrying is no more than 2 tons; And the hydraulic support weight of driving surface lifting now is 6.8t, so employed hoisting method can not be suitable in the prior art.
Summary of the invention
The objective of the invention is: provide a kind of hydraulic support convenient lifting appliance, it is easy to operate, quick, and the safety during work is good, and it can reduce potential safety hazard, to overcome the deficiency of prior art.
The present invention is achieved in that the convenient lifting appliance of hydraulic support, comprises two I-beam section crossbeams, is provided with fixed tray on the top at every I-beam section crossbeam two ends, is provided with the hanger that rises of two symmetrical distributions in the bottom of I-beam section crossbeam; Other is provided with the passing jack, and the telescopic section of passing jack is downward, is provided with the gib head pin-and-hole in the telescopic section termination of passing jack, on the gib head pin-and-hole, is connected with the suspension hook head; Top passing jack is provided with permanent seat, on permanent seat, is provided with pin-and-hole, and the pin of wearing that plays hanger passes pin-and-hole; Be connected through steady brace between the fixedly ear of passing jack and the permanent seat.
The spacing of described two I-beam section crossbeams is 1.6m.Such width can satisfy support and promote entrucking, does not influence the roadway support of operating location.
On steady brace, be provided with mounting ring.Mounting ring can increase the stability of passing jack, and it is fixing reliable to guarantee in use to pass jack.
Two passing of bonded assembly jack is connected with same Hydraulic Pump on the same I-beam section crossbeam, on the connecting line of passing jack and Hydraulic Pump, is provided with operating valve set and reversible lock.Hydraulic Pump is as hydraulic power; Adopt same Hydraulic Pump to connect with two passing jacks on the same I-beam section crossbeam; Passing jack on the different I-beam section crossbeams is connected on the different Hydraulic Pumps; Realizing that on the every I-beam section crossbeam two oil cylinders of passing jacks move simultaneously, and the irrelevant purpose of disturbing of oil cylinder of passing jack on two I-beam section crossbeams, when making things convenient for the support entrucking before and after the adjusting of bolt of rear end plate.By Hydraulic Pump hydraulic pressure (emulsion) is provided,, advances (returning) liquid mouth by reversible lock to what pass jack again, link to realize the purpose of HYDRAULIC CONTROL SYSTEM through high-pressure rubber pipe through manually operated operating valve set to two reversible lock.
Owing to adopt above-mentioned technical scheme; Compared with prior art; The present invention is employed on the I-beam section crossbeam and connects the structure of passing jack, and the I-beam section crossbeam is fixed on the back, utilize pass jack self fixedly ear as fixed part; When passing jack work,, make and pass jack as lifting tool as the attachment point of pushing and sliding, the operation of trying to stop people from fighting each other.The present invention can lift by crane hydraulic support fully, and whole lifting process only needs a skilled emulsification pump driver just can 6.8 tons of supports that fix be sling through control button, and is easy to operate, practices thrift a large amount of human resources.In addition, the contraction speed of passing jack is moderate, and height is shunk in control easily, and four passing jacks are stressed evenly, the phenomenon of falling the frame can not occur after the hydraulic support lifting, and is safe and reliable.The present invention is simple in structure, can adapt to the on-the-spot needs of underground work, not only can practice thrift the stock production time; Created good economic benefit and social benefit, also had great safe reliability, for the down-hole worker creates safe working environment; Create good safety benefit, result of use is desirable.
