Description
Technical field
The utility model relates to coal mine hydraulic supporting and withdraws apparatus field, and specifically, the utility model relates to a kind of symmetrical interchangeable Quick-return device.
Background technology
Colliery is comparatively heavy with large hydraulic support support body, so mobile and recall all very difficultly, Quick-return device is directly working surface hydraulic support to be reprinted to a kind of Quick-return device on transport vehicle, and former design can only be from withdrawing a side of platform.As shown in Fig. 1, hydraulic support is fixed on and withdraws platform left side, then by withdrawing device, hydraulic support is loaded on transport vehicle, but existingly withdraw platform connecting pin and guide rail is all fixed on a direction, when the hydraulic support work plane direction of recalling changes, this kind of structure can not meet down-hole and use, also to hydraulic support rope traction be disintegrated to assembling cavern by former mode, although there has been like this Quick-return device, but still exist and waste time and energy, delay work and waste the problem of investment, so original Quick-return stage apparatus can not be given full play to due effect.
Summary of the invention
Technical problem to be solved in the utility model is to provide and a kind ofly can two-wayly uses, symmetrical interchangeable Quick-return device.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of symmetrical interchangeable Quick-return device, comprise connection transition platform, middle transition platform, slippage guide rail, key seat one, key seat two, key seat three, key seat four and connecting pin, described slippage guide rail is placed in middle transition platform top one side, connecting transition platform is arranged on slippage guide rail, connect both sides, transition platform top and be fixed with respectively key seat one and key seat three, single head connecting pin is connected with key seat one, described key seat one and key seat three sides are provided with key seat two and key seat four side by side, on described sliding rail inner side edge, be provided with symmetrical double end connecting pin.
Described slippage guide rail is movably, is arranged on left side or the right side of middle transition platform.
Described single head connecting pin can be arranged on key seat one, key seat two, key seat three, key seat four.
Adopt the technical solution of the utility model, can obtain following beneficial effect:
The symmetrical interchangeable Quick-return device that the utility model provides, what solve existing underground work existence can not make full use of the problem that withdraws platform, has shortened the cycle of removing hydraulic support, has reduced labour intensity, has improved efficiency.Compare with original technology, the utility model connects key seat by increasing stage body, original single head connecting pin is become to double end connecting pin, solved in original technology can not symmetrical problem of exchanging, make hydraulic support in the more convenient and quicker that withdraws of mining face under mine, reduce colliery simultaneously and purchased the expense that two covers withdraw device, shorten the duration, reduced labour intensity, shortened labour hour, improve efficiency, also improved the utilization rate of Quick-return device.
Accompanying drawing explanation
The expressed content of each accompanying drawing of this manual and the mark in figure are made to brief description below:
Fig. 1 is original Quick-return platform structure schematic diagram;
Fig. 2 is Quick-return platform structure schematic diagram of the present utility model;
Fig. 3 is the Quick-return platform structure schematic diagram that in Fig. 2, slippage guide rail is placed in left side;
Mark in above-mentioned figure is: 1, connect transition platform; 2, middle transition platform; 3, slippage guide rail; 4, key seat one; 5, key seat two; 6, key seat three; 7, key seat four; 8, single head connecting pin; 9, double end connecting pin.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operating principle etc.
As shown in Figure 1, original stage apparatus that withdraws, comprise and connect transition platform 1, middle transition platform 2, slippage guide rail 3, stage body connects key seat 1, key seat 36 and stage body single head connecting pin 8 and forms, and this withdraws platform single head connecting pin 8 and slippage guide rail 3 is all fixed on a direction, when the hydraulic support work plane direction of recalling changes, this structure just can not be carried out withdrawing of underground hydraulic support frame.
As shown in Figure 2, symmetrical interchangeable Quick-return apparatus platform of the present utility model, comprise and connect transition platform 1, middle transition platform 2, push unit slippage guide rail 3, stage body connects key seat 1, key seat 25, key seat 36, key seat 47, single head connecting pin 8 and double end connecting pin 9 and forms, the connection transition platform 1 of symmetrical mounting with by single head connecting pin 8, be connected key seat one 4 connections being connected of middle transition platform 2 with stage body, between single head connecting pin 8 and key seat 1, with bearing pin, fix.Connect on transition platform 1 and increase side by side two key seats 25 and key seat 47 with key seat 1 and key seat 36, the single head connecting pin 8 of middle transition platform 2 is packed into key seat 1 and fixes with bearing pin.The original single head connecting pin 8 being fixedly connected with on slippage guide rail 3 is connected on key seat instead, and two single head connecting pins 8 are symmetrical arranged, two ends are fixed with bearing pin.Now, Quick-return platform is the device that hydraulic support withdrawing is loaded in left side.
Pack the single head connecting pin 8 of middle transition platform 2 into key seat 25, and after fixing with bearing pin, slippage guide rail 3 moves to the left side of middle transition platform 2, is provided with double end connecting pin 9 on slippage guide rail 3, two ends are fixing with bearing pin 6.Now, Quick-return platform is the device that hydraulic support withdrawing is loaded on right side.
The utility model connects key seat 25 and key seat 47 by increase, the connecting pin 8 that slippage guide rail 3 is connected with middle transition platform 2 becomes double end connecting pin 9, and change original stage body connecting pin structure being welded and fixed into dismountable single head connecting pin 8, connecting pin 8 is connected at diverse location with key seat 1, key seat 25, key seat 36, key seat 47, and carries out right and left mutually changing placement.Solve the problem that underground hydraulic support frame Quick-return is controlled by directionality, reduced cost, shortened the processing duration, raised labour efficiency, met the demand of underground work.In normal operation process, only key seat and single head connecting pin 8 transpositions can need to be solved to the problem of interchangeability, solved the out of use problem of Quick-return platform that the direction inconsistency due to work plane causes.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
