Technical field
The utility model relates to a kind of hydraulic pressure pulling shaft machine for the large-scale and high-end hydraulic support of dismantling coal mine fully-mechanized mining mechanization work face, belongs to the extracting tool technical field.
Background technology
Be subjected to the restriction of transport space, the large-scale and high-end hydraulic support of middle-size and small-size mine transports from the down-hole all will disintegrate into 2 to 3 as last, and must dismantle at working face.Because the downhole operations space is narrow and small and do not have specific hydraulic pulling shaft machine at present, working strength of workers is very big during the dismounting hydraulic support, and operating efficiency is very low, and production accident takes place easily.Therefore be necessary to develop the pulling shaft machine of a kind of suitable large hydraulic support and high-end hydraulic support, to satisfy the needs of Safety of Coal Mine Production.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of mining hydraulic pressure pulling shaft machine is provided, and to improve the removal efficiency of hydraulic support, reduces working strength of workers, satisfies the needs of Safety of Coal Mine Production.
The purpose of this utility model realizes with following technical proposals:
A kind of mining hydraulic pressure pulling shaft machine, comprise base, sliding seat, horizontal jack, vertical jack, crossbeam, steel wire rope, pulling shaft device and three pulleys in the formation, described sliding seat is installed on the base by horizontal line slide rail, and vertical jack is fixed on its top; The two ends of described horizontal jack are connected with sliding seat with base respectively; Described crossbeam is positioned at vertical jack top, and its middle part is connected with the push rod of vertical jack; First pulley is installed on the sliding seat, and second pulley and the 3rd pulley are installed in the two ends of crossbeam respectively, and an end of described steel wire rope is fixed on the crossbeam, and the other end links to each other with the pulling shaft device behind pile warp first pulley, second pulley and the 3rd pulley successively.
Above-mentioned mining hydraulic pressure pulling shaft machine, described horizontal jack and vertical jack are provided with hydraulic lock, and laterally hydraulic lock and the operating valve set of jack and vertical jack all are fixed on the sidewall of vertical jack.
Above-mentioned mining hydraulic pressure pulling shaft machine is provided with the pulling shaft jack in the described pulling shaft device.
The horizontal jack of the utility model utilization drives the pulling shaft device and moves forward and backward, and utilizes vertical jack to regulate the pulling shaft height of devices simultaneously, makes the pulling shaft device be in the optimum position of the big bearing pin of dismounting.Use this pulling shaft machine can reduce working strength of workers greatly, improve dismounting large-scale and the operating efficiency of high-end hydraulic support and the security of operation, thoroughly solved big bearing pin in the not easily detachable difficult problem of mining face under mine.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Each label is among the figure: 1, base; 2, horizontal jack; 3, sliding seat; 4, steel wire rope; 5-1, first pulley; 5-2, second pulley; 5-3, the 3rd pulley; 6, crossbeam; 7, vertical jack; 8, operating valve set; 9, hydraulic lock; 10, pulling shaft device; 11, pulling shaft jack.
The specific embodiment
Referring to Fig. 1, the utility model comprises base 1, horizontal jack 2, sliding seat 3, steel wire rope 4, the first pulley 5-1, the second pulley 5-2, the 3rd pulley 5-3, crossbeam 6, vertical jack 7, operating valve set 8, hydraulic lock 9, pulling shaft device 10, and pulling shaft device 10 is provided with pulling shaft jack 11.
The utility model leans on the telescopic drive pulling shaft device 10 of jack to carry out up and down and moves forward and backward.Each hydraulic cylinder all is furnished with hydraulic lock, and this pulling shaft machine is mainly used in the fast quick-detach of the big bearing pin of hydraulic support, reaches safely, puies forward the purpose of effect.When using this equipment to dismantle big bearing pin, easy to operate, flexibly, stable action, pulling shaft device 10 can rest on any desired location, and big bearing pin dismantlement work safety coefficient is improved greatly.
This pulling shaft machine total length 2.2m, wide 1.5 m, high 1. 5-2.3 m, each parts is based on the bearing pin connection, and small part is by Bolt Connection.Laterally the stroke of jack 2 is 900mm, can drive sliding seat 3 and move forward and backward.Vertically the stroke of jack 7 is 1000mm, and it is as the support of crossbeam 6, and can drive crossbeam 6 and move up and down, and realizes the lifting of pulling shaft device and highly adjusting.The stroke of pulling shaft jack 11 is 300mm, is installed in pulling shaft device 10 inside, is used for pulling out the big bearing pin of hydraulic support.This pulling shaft machine utilizes the big flow operating valve set of one group of 400L 8 as operating system, and each hydraulic cylinder is installed the hydraulic lock of 200L, advances back liquid and adopts φ 16 high-pressure hoses.
This pulling shaft machine can be gone into the well on the whole, and the dismounting of needn't disintegrating is easy to use.Equipment utilizes working face to have pumping plant now after arriving working face, and connecting enterprising liquid back pipe road can use, simple to operate, flexible.When pumping plant pressure is 23Mpa, the pulling force of pulling shaft device can reach 33 tons, this equipment not only is applicable to the hydraulic support of 1.5 meters centre-to-centre spacing, and can also satisfy the dismounting requirement of the high-end hydraulic support of centre-to-centre spacing more than 1.75 meters, the large-scale and high-end hydraulic support that has thoroughly solved coal mine fully-mechanized mining mechanization work face connects the dismounting difficult problem of macro-axis.
