Abstract

The utility model relates to a device for pushing in a kiln car. The utility model has a main structure that a pulley is installed on guide rails of a machine frame; the lower side of the pulley is welded with a connecting plate; a hydraulic cylinder is arranged on the machine frame under the pulley; the connecting plate is connected with one end of a piston rod. Thus, the utility model has the advantages of compact and simple structure and capability of increasing integral stability.

Description

The hydraulic pressure kiln car pusher

The utility model relates to a kind of kiln car and heads into equipment.

The kiln car equipment of heading into of present domestic use has mechanical type kiln car pusher and fluid pressure type kiln car pushers such as chain type, spiral, rack-and-pinion, and mechanical type kiln car pusher overall structure is comparatively complicated, and volume is bigger, heaviness; The coaster of fluid pressure type kiln car pusher and the piston rod of hydraulic cylinder are directly hinged, are a straight line and arrange, and cause overall structure long, less stable, and the fabrication and installation expense is higher; The push plate of traditional kiln car pusher is fixed on the push rod, and directly pushing tow kiln car car body end face causes the kiln car car body to damage easily, and kiln car pusher need be installed in outside the kiln, takies space.

In view of this, the purpose of this utility model provides a kind of hydraulic pressure kiln car pusher, and it is with hydraulic pressure coaster linear reciprocating motion on guide rail, drives kiln car and enters tunnel cave.

The purpose of this utility model is achieved in that it comprises that top has the frame of guide rail, coaster and have the hydraulic cylinder of piston rod, it is characterized in that: coaster is installed on the guide rail of frame, be welded with gusset piece below the coaster, hydraulic cylinder device is on the frame below the coaster, and gusset piece is connected with tailpiece of the piston rod again.

Have balladeur train on the described coaster, and this balladeur train is provided with the pushing tow pawl that several can lodge, this pushing tow pawl bottom is welded with base plate.

Described frame side is provided with travel switch, and described coaster side is provided with corresponding switch contact.

Because adopt such scheme: coaster, hydraulic cylinder and frame link together, make compact equipment, simple, increase whole stability, can be contained in below the kiln car of tunnel cave arrival end, so be difficult for occupying space.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments schematic diagram;

The side view of Fig. 2 the utility model exemplary embodiments Fig. 1.

By accompanying drawing 1-2 as seen, present embodiment is made up of frame 2, coaster and hydraulic cylinder 3.

Frame 2 plays the effect of fixer cylinder pressure 3, supporting coaster, for steel construction is welded in the bottom of complete machine.Coaster is on the top of frame 2, its effect is to promote kiln car by pushing tow pawl 6 to advance, it mainly is made up of balladeur train 8, road wheel 10, pushing tow pawl 6 etc., balladeur train 8 is welded by shaped steel, steel plate etc., several pushing tow pawls 6 are installed on the balladeur train 8, this pushing tow pawl 6 (as: unidirectional ratchet, the genus prior art) bottom is welded with base plate 11, have counterweight and stable effect, make pushing tow pawl 6 state of can being kept upright under normal conditions, when the coaster rollback, after being obstructed, pushing tow pawl 6 can freely lodge, and crossing resistance just can be upright automatically; Be equipped with manyly under the coaster, can move back and forth along the guide rail 9 of frame 2 to road wheel 10.Below coaster, be welded with gusset piece 7, be used for the piston rod of coaster and hydraulic cylinder 3 is coupled together.Hydraulic cylinder 3 is the drive part of hydraulic pressure kiln car pusher below coaster, and the afterbody of hydraulic cylinder 3 connects with frame 2 usefulness gusset pieces 1, like this, frame 2 and coaster is linked together, and provides power by Hydraulic Station, promotes coaster and moves reciprocatingly.For realizing control automatically and adjusting the needs of locating, in the side of frame 2 travel switch 4 has been installed, cooperate with the switch contact 5 of coaster side installation, the control coaster is finished each working cycles automatically.

Using method of the present utility model is, during work, start the Hydraulic Station fuel feeding, hydraulic cylinder works, piston rod stretches out, drive the guide rail movement of coaster along frame, the push block that pushing tow pawl pushing tow kiln car bottom is ad hoc heads into kiln car in the tunnel cave, can be once or the substep jacking, after the stroke of kiln car met technological requirement, travel switch contacted with the switch contact, and coaster stops; During the coaster rollback, the hydraulic cylinder oil return, piston rod is regained, and the pushing tow pawl lodging back coaster that is hampered just freely withdraws under the kiln car and returns the home position.

The utility model has the advantages that, owing to adopt up and down mounting structure, make device structure comparatively compact, simple, increase The stability that adds its integral body; Several pushing tow pawls are installed on the coaster, and the pushing tow pawl under external force can be at certain angle Lodging in the scope makes the hydraulic pusher can be once or substep jacking kiln car; Anti-overload ability is strong, can be with automatic control System networking operation, accurate positioning, reliable operation can be installed in below the kiln car of tunnel cave arrival end and not account in addition building The space. It is the special equipment for tunnel cave arrival end top car.
