The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further described:
A kind of hydraulic pin releaser, as shown in Figure 1 and Figure 2, comprise jack 6, jack 6 comprises base 10 and telescopic mast 11, base 10 lower ends are fixedly connected with backboard 7, and band has and moves back lock-joint 9 on the backboard 7, and telescopic mast 11 upper ends are fixedly connected with jack draw back plate 3, be connected with connection screw mandrel 8 on the jack draw back plate 3, connect screw mandrel 8 lower ends and pass from moving back lock-joint 9.Described connection screw mandrel 8 is flexible connection with jack draw back plate 3, connects screw mandrel 8 upper ends and passes jack draw back plate 3, connects screw mandrel 8 upper ends and is threaded, and connects screw mandrel 8 upper end screw threads and is connected with limit screw cap 1, connects screw mandrel 8 lower ends and also is threaded.Described hydraulic pin releaser comprises two or more jack 6.Described base 10 upper ends are fixedly connected with front apron 4, have port 12 on the front apron 4, and described connection screw mandrel 8 passes in port 12.Be installed with cushion block 2 on the described connection screw mandrel 8, cushion block 2 is between described limit screw cap 1 and jack draw back plate 3.Fixedly connected jug 5 on the described base 10.
Embodiment recited above is described preferred implementation of the present invention; be not that design of the present invention and scope are limited; under the prerequisite that does not break away from design concept of the present invention; common engineers and technicians make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
As shown in Figure 4, during use, at first the lock-joint that moves back on the backboard of this pin releaser is fixed on the square cotter seat, simultaneously the telescopic mast of jack is regained fully, to connect screw mandrel is tightened on the rack pin shaft, tighten limit screw cap then, pin releaser is combined by being connected screw mandrel with bearing pin, at this moment, the manipulation valve is given jack feed flow (referring to Fig. 3), and the telescopic mast of jack is stretched out, and produces outside powerful pulling force by connecting filament pole pair rack pin shaft, thereby bearing pin is overcome and the support pin-and-hole between resistance, bearing pin is therefrom withdrawed from.
The present invention produces stronger thrust when utilizing the jack action, pulling in the other direction overcomes the resistance of axis hole by connecting the bearing pin that screw mandrel connects, and makes it break away from support body.
Application of the present invention can change adopts chain block to move back the method for pin in the past, increase work efficiency, shorten support disintegration construction period, greatly reduce on-the-spot worker's labour intensity, save a large amount of man-hours, according to 2 support disintegration quantity survey (surveying)s of many increases every day, finish whole work, can save 20,000 yuan of work time costs, reduce surplus the support lease expenses nearly 100,000 yuan, surplus the expense of cutting down expenses altogether 120,000 yuan.
The present invention adopts the control of remote control valve, and is safe and reliable, ensures for realizing that safe construction provides reliably.
