The hydraulic roof-contact device has the following advantages: (1) the hydraulic roof-contact device is hydraulically driven, so that the heavy manual labor of personnel is reduced; (2) mechanized operation is realized and the operating efficiency is high; (3) the adaptability is strong, and application is wide and the hydraulic roof-contact device can be mounted on any equipment requiring roof-contact; and (4) the roof-contact rod is connected with the roof-contact plate through the spherical face to adapt to local unevenness and inclination of the roof-contact plate, and as the contact area between the roof-contact plate and the roof-contact plate is large, the roof-contact stability is good.
Description
Technical field
The utility model relates to the mine mechanism field, is that a kind of hydraulic pressure of a kind of sinking and drifting face connects ejection device specifically.
Background technique
Mining face under mine often takes to connect the method on top when temporary fixed certain equipment.Traditional top method that connects is: stand in the tunnel with a round log, a lumps of wood is respectively put on below round log and round log top, uses below the timber wedge stretching between round log and the lumps of wood, round log is fixed, and then the equipment that will need to fix is fastened on round log.The method is not only wasted a large amount of human and material resources, and it is bad to connect the top effect, and security incident easily occurs when connecing the ejection device unstability poor stability.
The model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of mechanical type and connects ejection device, not only high working efficiency, 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 and is connecing on the base of ejection device, connect ejection device base below be fixed with supporting frame, support frame as described above work contacts with ground the time; In described outer square chest, slideway is set, movable square chest is set on described slideway, connect the top jack and be arranged in outer square chest; The piston rod part and the movable square chest that connect the 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, arranges in sleeve and connects push rod, connects push rod and connects top board.
The described push rod top of connecing is spheroid, and described spheroid coordinates with the spherical groove that connects the top board bottom.
Described outer square chest is connected by bearing pin with base, and outer square chest jack is fixed on base, and outer square chest jack piston and outer square chest are coupling.
The utility model has the advantages that:
(1) by hydraulic driving, reduce personnel's heavy physical labour;
(2) realize mechanized operation, high working efficiency;
(3) strong adaptability is widely used, and this device can be arranged on the equipment that any needs connect the top;
(4) connecing top board is that sphere is connected with connecing push rod, can adapt to injustice and the inclination of top board part, and the area of contact that connects top board and top board is large, connects the top good stability.
(5) be connected one group of outer square chest jack between outer square chest and base, flexible by outer square chest jack, can adjust outer square chest is erectility or level.Being erectility during work, is level during transportation.
Description of drawings
Fig. 1 is general structure schematic diagram of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the ejection device structural drawing that connects of the present utility model.
Embodiment
Illustrate the utility model below in conjunction with accompanying drawing, as shown in Figure 1-Figure 3, the utility model comprises outer square chest 5, and outer square chest 5 is connected through the hinge on the base 9 that connects ejection device, be fixed with supporting frame 20 below outer square chest 5, contact with ground during support frame as described above 20 work; The interior slideway that arranges of described outer square chest 5 arranges movable square chest 3 on described slideway, connect top jack 4 and be arranged in outer square chest 5; Movable square chest 3 is coupling with the piston that connects top jack 4, and 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 12 li settings of sleeve connect push rod 2, connect push rod 2 and connect top board 1.
Even for proof stress, to adapt to injustice and the inclination of top board part, connect top board 1 large with the area of contact that connects push rod 2, connect the top good stability.Described push rod 2 tops of connecing are spheroid 21, and described spheroid 21 coordinates with the spherical groove that connects top board 1 bottom.
The convenience of transportation when guaranteeing that connect 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 the piston of outer square chest jack 10 and outer square chest 5 are coupling.
By stretching of outer square chest jack, can adjust outer square chest is erectility or level.Being erectility during work, is level during transportation.
Working principle of the present utility model
This hydraulic pressure connect ejection device be with emulsion pump as power source, flexible by jack drives the motion of flexible square chest, and will connect a kind of hydraulic pressure that ejection device is directly installed on equipment and connect ejection device.
This hydraulic pressure connects ejection device an outer square chest, and outer square chest is connected through the hinge and is connecing on the base of ejection device, by stretching of outer square chest jack, can adjust the position of outer square chest, that is: outer square chest can rotate around bearing pin, can vertically stand when needing, and implements to connect top work.During transportation, can horizontal positioned, save the 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 the top jack and is driven, and when work, jack piston rod stretches out, and promotion activity square chest moves upward.
A sleeve is equipped with on the top of movable square chest, is equipped with one in sleeve and connects push rod, and 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, contact with top board until connect top board, the top work that connects is completed in compacting.
The base that connects ejection device is mounted on the concrete equipment in down-hole, during equipment moving, does not connect top work, and connecing ejection device can be with equipment moving.
