ST buffer hydraulic pressure kludge
Technical field
The utility model belongs to the maintenance of ST buffer and assembling utensil of rolling stock.
Background technology
In the operation of ST buffer extensive use mining, be applied to especially the overturning certainly in the mine railway vehicle.Because mine operation intensity is high, mineral weight is large, and the ST buffer is stressed to be concentrated, and the screw rod on it is easily broken, causes the ST buffer to scatter, if the ST buffer that more renews, cost pressure is large, and causes very large waste.If but workman oneself assembling ST buffer is quite hard during nut on tightening screw rod because spring is equipped with in its inside, needs at least two people to operate simultaneously, the wasting manpower and material resources.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of ST buffer hydraulic pressure assembling
Machine, it can be assembled the nut on the ST buffer easily, has improved operating efficiency.
A kind of ST buffer of the utility model hydraulic pressure kludge, it is characterized in that: it comprises hydraulic part and mechanical part, hydraulic part comprises hydraulic cylinder, three-position four-way valve, overflow valve, filter, hydraulic pump, fuel tank, hydraulic cylinder, three-position four-way valve, filter, hydraulic pump are linked in sequence by oil pipe, are connected overflow valve, fuel tank by a side oil pipe between three-position four-way valve and filter; Mechanical part comprises supporting part, press-fits part; Supporting part comprises frame, main loading plate, front support plate, rear support plate, posting, roller bearing, front support plate, rear support plate are welded on frame, main loading plate is two of up and down, the rear support plate is arranged in the frame of main loading plate, main loading plate passes in the frame of support plate in the past, and all by being welded to connect, posting is two for main loading plate and front and back support plate, it inserts in main carrying sheet frame, and be between the support plate of front and back, roller bearing is arranged on frame, and near posting; Press-fit portion is divided and is comprised pressure head, briquetting, limit switch, pressure head is connected on the hydraulic cylinder piston rod that is placed in main carrying sheet frame, briquetting is arranged on base plate, be between front support piece and posting, the center is processed with a hole, limit switch is fixedly connected on frame, is between briquetting and posting.
When using this Novel assembling machine, with crane gear, buffer is hung in posting, be placed on roller bearing, hydraulic pump starts work and enters (the left position of three-position four-way valve), limit switch pressurize (three-position four-way valve meta) is encountered in the buffer front portion, with sleeve by the hole in the middle of briquetting with buffer nut check, hydraulic cylinder is return (the right position of three-position four-way valve valve), the buffer assembling finishes.
Adopt this New type of S T buffer hydraulic pressure kludge, saved cost, avoided unnecessary waste, and simple to operate, safe and reliable, and actual implementation result is good.

The specific embodiment
From Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 as can be known, this novel a kind of ST buffer hydraulic pressure kludge, it comprises hydraulic part and mechanical part.
Hydraulic part comprises hydraulic cylinder 11, three-position four-way valve 12, overflow valve 14, filter 15, hydraulic pump 16, fuel tank 17, hydraulic cylinder 11, three-position four-way valve 12, filter 15, hydraulic pump 16 are linked in sequence by oil pipe, are connected overflow valve 14, fuel tank 17 by a side oil pipe between three-position four-way valve 12 and filter 15.
Mechanical part comprises supporting part, press-fits part; Supporting part comprises frame 1, main loading plate 2, front support plate 3, rear support plate 4, posting 6, roller bearing 9, front support plate 3, rear support plate 4 are welded on frame 1, main loading plate 2 is two of up and down, rear support plate 4 is arranged in the frame of main loading plate 2, main loading plate 2 passes in the frame of support plate 3 in the past, main loading plate 2 and front and back support plate 3,4 are all by being welded to connect, posting 6 is two, it inserts in main loading plate 2 frames, and be between the support plate 3,4 of front and back, roller bearing 9 is arranged on frame 1, and near posting 6; Press-fit portion is divided and is comprised pressure head 5, briquetting 7, limit switch 8, pressure head 5 is connected on hydraulic cylinder 11 piston rods 10 that are placed in main loading plate 2 frames, briquetting 7 is arranged on base plate 1, be between front support piece 3 and posting 6, the center is processed with a hole, limit switch 8 is fixedly connected on frame 1, is between briquetting 7 and posting 6.
For controlled pressure better, hydraulic part also comprises hydralic pressure gauge 13, and hydralic pressure gauge 13 is arranged between three-position four-way valve 12 and filter 15.
In order to adapt to the ST buffer of different model, briquetting 7 can move left and right between limit switch 8 and front support plate 4, and the position of briquetting 7 is adjustable like this.
During use, with crane gear, buffer is hung in posting 6, be placed on roller bearing 9.When hydraulic pump 17 starts, three-position four-way valve 12 is in left position, the piston rod 10 of hydraulic cylinder 11 stretches out, make the pressure head 5 on it promote buffer forward, make the front portion of buffer encounter limit switch 8, at this moment three-position four-way valve 12 is in meta and pressurize, again with sleeve by the nut check of the hole in the middle of briquetting 7 with buffer, at this moment three-position four-way valve 12 is in right position, and hydraulic cylinder 11 is return, and the buffer assembling finishes.
