Description
Technical field
The utility model relates to a kind of repair demolition instrument, relates in particular to a kind of steelframe Shi Lama that is used for the mine car maintenance.
Background technology
Mine car is as the main means of transport of mine laneway, and along with the developing of down-hole, mine engineering is extended, the transportation mine car also increases thereupon, and the work of maintenance mine car is heavy day by day.The mine car parts of easy damage is exactly a mine tram wheel, at present, and the screw rod pulley extractors that adopt in the mine tram wheel maintenance more, during operation the dismounting time-consuming, labour intensity is big, inefficiency, and phenomenons such as screw rod stripped thread, hook fracture often take place, very easily operating personnel are caused actual bodily harm.
The utility model content
The utility model is in order to solve weak point of the prior art, provide a kind of simple in structure, labour intensity is little, high efficiency, low, the safe and reliable steelframe Shi Lama that is used for the mine car maintenance of cost.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: be used for the steelframe Shi Lama of mine car maintenance, it comprises a framework, is provided with jacking-drawing device in the framework.
Described framework comprises top board and the base plate that be arranged in parallel, is provided with column between top board and the base plate, and jacking-drawing device is arranged on the top board bottom, and base plate is provided with the strip opening that is communicated with a lateral edges.
Described top board top is provided with stiffener, can strengthen the intensity of top board.
Described jacking-drawing device is a hydraulic jack.
Adopt said structure, in the strip opening of wheel shaft with mine car through base plate, mine tram wheel is placed on the base plate inner face, the base of hydraulic jack and piston hold out against Bogie truck axles and top board inner face respectively, operate hydraulic jack then, the piston elongation of hydraulic jack, whole framework drives mine tram wheel and moves relative to Bogie truck axles, so just very effortlessly mine tram wheel is pulled out; The utility model is simple in structure, sturdy and durable, safe and reliable, laborsaving to save time, in light weight, easy to carry, not limited by the place, be applicable to various repairings place, mine, worth industrial and mining enterprises apply.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that A-A of Fig. 1 is to cutaway view.
The specific embodiment
As depicted in figs. 1 and 2, the steelframe Shi Lama that is used for the mine car maintenance of the present utility model, it comprises a framework, be provided with jacking-drawing device 3 in the framework, jacking-drawing device 3 is a hydraulic jack, framework comprises square top board 1 and the base plate 2 that be arranged in parallel, top board 1 and base plate 2 all adopt steel plate to be made, be welded with four root posts 4 between four jiaos of top board 1 and base plate 2 respectively, column 4 can adopt angle steel or bar steel plate, jacking-drawing device 3 is arranged on top board 1 bottom, and base plate 2 is provided with the strip opening 5 that is communicated with a lateral edges, and top board 1 top is welded with stiffener 6.
During use, in the strip opening 5 of wheel shaft with mine car through base plate 2, mine tram wheel is placed on base plate 2 inner faces, the base 7 of jacking-drawing device 3 and piston 8 hold out against Bogie truck axles and top board 1 inner face respectively, operate the rocking bar 9 of jacking-drawing device 3 then, piston 8 elongations of hydraulic jack, whole framework drives the relative Bogie truck axles of mine tram wheel and moves up, so just very effortlessly mine tram wheel is pulled out from Bogie truck axles, can keep in repair mine tram wheel easily.
