Description
Technical field
The present invention relates to mine mechanism field, is that a kind of hydraulic pressure of a kind of sinking and drifting face connects ejection device specifically.
Background technology
Mining face under mine, when temporary fixed certain equipment, often takes the method connecing top.Traditional top method that connects is: stand in tunnel with a round log, and one block of lumps of wood is respectively put on below round log and round log top, uses timber wedge stretching below, round log is fixed between round log and the lumps of wood, and then will fixing equipment be needed to fasten on round log.The method not only wastes a large amount of human and material resources, and it is bad to connect top effect, and poor stability, easily security incident occurs when connecing ejection device unstability.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of mechanical type and connect ejection device, not only operating efficiency is high, and easy construction, and stability is high.Concrete scheme is as follows:
A kind of hydraulic pressure of a kind of sinking and drifting face connects ejection device, and this hydraulic pressure connects ejection device an outer square chest, and outer square chest is connected through the hinge on the base connecing ejection device, and outer square chest jack is fixed on base, and piston and the outer square chest of outer square chest jack are coupling; Bracing frame is fixed with, during support frame as described above work and earth surface below the base connecing ejection device; In described outer square chest, slideway is set, described slideway arranges movable square chest, connect top jack and be arranged in outer square chest; The piston rod part and the movable square chest that connect top jack are coupling, and movable square chest can be slided along the slideway of outer square chest, and the top of movable square chest arranges sleeve, arrange and connect push rod, connect push rod and connect top board in sleeve.
The described push rod top that connects is spheroid, described spheroid and the spherical slot fit connect bottom top board.
Described outer square chest and base are by pinned connection, and outer square chest jack is fixed on base, and outer square chest jack piston and outer square chest are coupling.
Advantage of the present invention is:
(1) by hydraulic-driven, the heavy physical labour of personnel is reduced;
(2) realize mechanized operation, operating efficiency is high;
(3) strong adaptability, is widely used, and this device can be arranged on any needs and connect on the equipment on top;
(4) connecing top board with connecing push rod is that sphere is connected, and can adapt to injustice and the inclination of top board local, the contact area connecing top board and top board is large, connects top good stability.
(5) outer square chest be connected one group of outer square chest jack between base, flexible by outer square chest jack, can adjust outer square chest is erectility or level.Being erectility during work, is level during transport.
Accompanying drawing explanation
Fig. 1 is general structure schematic diagram of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 of the present inventionly connects ejection device structure chart.
Detailed description of the invention
Illustrate the present invention below in conjunction with accompanying drawing, as shown in Figure 1-Figure 3, the present invention includes outer square chest 5, outer square chest 5 is connected through the hinge on the base 9 connecing ejection device, is fixed with bracing frame 20 below outer square chest 5, when support frame as described above 20 works and earth surface; In described outer square chest 5, slideway is set, described slideway is arranged movable square chest 3, connect top jack 4 and be arranged in outer square chest 5; Movable square chest 3 with connect the piston pushing up jack 4 and be coupling, movable square chest 3 can be slided along the slideway of outer square chest 5, and the top of movable square chest 3 arranges sleeve 12, and sleeve 12 li of settings connect push rod 2, connects push rod 2 and connects top board 1.
For proof stress is even, to adapt to injustice and the inclination of top board local, connect top board 1 large with the contact area connecing push rod 2, connect top good stability.Described push rod 2 top that connects is spheroid 21, described spheroid 21 and the spherical slot fit connect bottom top board 1.
For ensureing the convenience connecing transport when ejection device does not use, described outer square chest 5 is connected by bearing pin 7 with base 9, and outer square chest jack 10 is fixed on base 9, and piston and the outer square chest 5 of outer square chest jack 10 are coupling.
Stretching by outer square chest jack, can adjust outer square chest is erectility or level.Being erectility during work, is level during transport.
Operating principle of the present invention
It is with emulsion pump as power source that this hydraulic pressure connects ejection device, flexible by jack, drives the motion of flexible square chest, and connects ejection device by connecing a kind of hydraulic pressure that ejection device is directly installed on equipment.
This hydraulic pressure connects ejection device an outer square chest, and outer square chest is connected through the hinge on the base connecing ejection device, stretching by outer square chest jack, the position of outer square chest can be adjusted, that is: outer square chest can rotate around bearing pin, can vertically stand when needing, and implements to connect top work.During transport, can horizontal positioned, save space.
Movable square chest is contained in outer square chest, can slide along the slideway of outer square chest, and the slip of movable square chest is abutted against top jack and is driven, and operationally, jack piston rod stretches out, and promotion activity square chest moves upward.
A sleeve is equipped with on the top of movable square chest, and be equipped with one in sleeve and connect push rod, connecing push rod top has a spheroid, and spheroid connects one and connects top board.When movable square chest moves upward, connect top board and also move upward simultaneously, until connect top board and top plate contact, compacting, complete and connect top work.
The base connecing ejection device is mounted on the concrete equipment in down-hole, and during equipment moving, do not carry out connecing top work, connecing ejection device can with equipment moving.
