The utility model discloses only through simply fixing of device and applying of pressure, can reduce the large -scale accessory change degree of difficulty effectively with selling not hard up extracting, improvement work efficiency, personnel's safety is effectively ensured in the damage that reduces equipment.
Description
Technical field
The utility model relates to a kind of main equipment and to pull pin axle instrument, belongs to industrial equipment development field.
Background technology
In the main equipment processes such as routine dismounting coal support, frequent appearance connects bearing pin and pulls out the situation connecing difficulty, general processing mode uses percussion hammer process, this mode is time-consuming, effort, more long-time shortage, safeguards and stressed larger position bearing pin can not use this kind of scheme, can only use some dangerous modes, has not only added hidden danger but also easy damaged equipment part, according to this type of situation, design a kind of convenient and swift safe special pulling pin and just seem particularly important.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of main equipment to pull pin axle instrument.
In order to solve the problems of the technologies described above, the utility model comprises high-pressure pump, bracing frame, hydraulic nut and threaded rod, and hydraulic nut is fixed on bracing frame, and high-pressure pump is communicated with hydraulic nut by high-pressure hose, and hydraulic nut is threaded with threaded rod.
In order to meet pulling pin of differing heights requirement, described bracing frame comprises upper plate, lower plate, screw rod and nut, the middle part of upper plate is provided with hydraulic nut fixing hole, hydraulic nut is fixed in hydraulic nut fixing hole, there is the screw rod moving up and down through upper plate the corner of upper plate, and the lower end of screw rod is fixed in lower plate, each screw rod there are two nuts be connected with screw flight, a nut is on upper plate, a nut is below upper plate, lower plate is provided with the gap that threaded rod is passed through, by the movement of nut with fixingly will regulate the height of upper plate, thus change the height of threaded rod.
Skew is not produced in the course of the work in order to instrument can be made.Described lower plate has two, and two lower plates lay respectively at the both sides of threaded rod.Each lower plate is fixed with main equipment clamping device.
In order to carry out clamping and fixing for the difform workpiece that pulled out, described clamping device comprises two clamp bracket, two clamp bracket are separately fixed at the two ends of lower plate, each clamp bracket is provided with bolt, point-blank or be parallel to each other, the central shaft of the bolt in two lower plates is parallel to each other the central shaft of the bolt in each lower plate.
The beneficial effects of the utility model are: bearing pin, by means of only the applying of the simply fixing of device with pressure, effectively can loosen and extract, reduce large-scale member replacing difficulty, increase work efficiency by the utility model, and the safety of personnel is also effectively guaranteed in the damage reducing equipment.

Detailed description of the invention
A kind of main equipment according to Fig. 1 is pulled pin axle instrument, comprise high-pressure pump 1, bracing frame 3, hydraulic nut 4 and threaded rod, hydraulic nut 4 is fixed on bracing frame 3, and high-pressure pump 1 is communicated with hydraulic nut 4 by high-pressure hose 2, and hydraulic nut 4 is threaded with threaded rod 5.
Bracing frame 3 according to Fig. 2 comprises upper plate 301, lower plate 304, screw rod 303 and nut 302, the middle part of upper plate 301 is provided with hydraulic nut fixing hole, hydraulic nut 4 is fixed in hydraulic nut fixing hole, there is the screw rod moving up and down 303 through upper plate 301 corner of upper plate 301, and the lower end of screw rod 303 is fixed in lower plate 304, each screw rod 303 there are two nuts 302 be threaded with screw rod 303, a nut 302 according to Fig. 4 is on upper plate 301, a nut 302 is below upper plate 301, lower plate 304 is provided with the gap that threaded rod 5 is passed through.
Lower plate according to Fig. 3 has two, and two lower plates 304 lay respectively at the both sides of threaded rod 5.Each lower plate 304 is fixed with main equipment clamping device, clamping device comprises two clamp bracket 306, two clamp bracket 306 are separately fixed at the two ends of lower plate 304, each clamp bracket 306 is provided with bolt 305, point-blank or be parallel to each other, the central shaft of the bolt 305 in two lower plates 304 is parallel to each other the central shaft of the bolt 305 in each lower plate 304.
Using method: be communicated with high-pressure pump 1 and hydraulic nut 4 with high-pressure hose 2, threaded rod 5 is tightened on hydraulic nut 4, split for the lower end aligned of threaded rod 5 bearing pin 6 is screwed into the inside, again all bolts 305 on clamping device are tightened inwards, lower plate 304 is not loosened, nut 302 on adjusting support frame 3 makes threaded rod move to suitable height, fixes nut 302, opens high-pressure pump 1 and just can dismantle simple fast for bearing pin from split equipment 7.
