Specific embodiment

The technical solution of the utility model is described in further detail with reference to the accompanying drawings and examples.

As shown in Figures 1 to 3, which keeps off a car thick stick comprising keep off a car thick stick ontology 2 and top plate 9, top Plate is located at right above thick stick ontology of keeping off a car and close to thick stick ontology head end of keeping off a car, and top board undersurface is fixedly installed with the first fixed pulley 5, keeps off a car 2 upper surface middle part of thick stick ontology is provided with mounting base 8, and the cylinder barrel of cylinder 3 is fixedly mounted in mounting base, covers on the cylinder barrel head end of cylinder Equipped with support 4, the top of support is fixedly installed with the second fixed pulley 6, and the piston rod end of cylinder is connected with movable pulley 7, keeps off a car The head end of thick stick ontology 2 is fixedly connected with 10 one end of wirerope, and wirerope successively bypasses the first fixed pulley 5, the second fixed pulley 6, moves The other end is fixedly connected with the upper surface for thick stick ontology of keeping off a car after pulley 7；Thick stick ontology tail end of keeping off a car is fixedly hinged with by pin shaft Fixed board 1.

Above-mentioned the first fixed pulley 5, the second fixed pulley 6 and movable pulley 7 is located at same vertical plane, can effectively prevent steel wire Rope 10 generates skewness at work, and the movement of thick stick ontology 2 that causes to keep off a car has some setbacks, and the abrasion of wirerope is accelerated to cause wirerope Service life reduce.

It is opened up in the middle part of above-mentioned 2 upper surface of thick stick ontology of keeping off a car there are two symmetrical strip-shaped hole 2.1, strip-shaped hole is located at peace Fill the lower section of seat 8, the upper surface of mounting base is opened up there are two symmetrical circular hole 8.1, two circular holes respectively with two strip-shaped holes Corresponding, mounting base, by being connected through the bolt of circular hole and strip-shaped hole, can be drawn with thick stick ontology of keeping off a car in wirerope 10 By adjusting the front-rear position of mounting base 8 when long, achieve the purpose that nervous wirerope, effectively avoid due to wirerope is elongated Prevent thick stick ontology 2 of keeping off a car is from being restored to initial position.

Above-mentioned 2 head end upper surface of thick stick ontology of keeping off a car, middle part upper surface are fixedly connected to the retainer plate 2.2 being in U-shape, and The retainer plate of middle part upper surface is located at the lower section of cylinder 3, the both ends of wirerope 10 pass through clamping chuck respectively with two fixations Circle 2.2 is connected, and wirerope 10 and thick stick ontology 2 of keeping off a car can be made easy to disassemble by the retainer plate of setting, to play conveniently more The purpose of change steel rope is set to the underface of cylinder by the other end of wirerope, can pass through reasonable wirerope-winding side Formula realizes the Double-stroke of cylinder elongation, under the premise of guaranteeing to keep off a car thick stick ontology Lift, thoroughly solves cylinder The inconvenient problem of replacement, maintenance.

It keeps off a car in thick stick in the utility model underground mine use Integral pneumatic, cylinder is connected with operation control box, operation control Case processed connects with gas source, controls the work of cylinder.

The utility model underground mine use Integral pneumatic is kept off a car the course of work of thick stick are as follows: needs to open thick stick ontology 2 of keeping off a car When, the piston rod of cylinder 3 is stretched out by operation control box, drives movable pulley 7 mobile to thick stick ontology head end of keeping off a car, so that steel wire Restrict 10 it is equidirectional be pushed into, so that the tail end for the thick stick ontology 2 that makes to keep off a car is rotated around the bottom end of fixed plate 1, so that thick stick ontology of keeping off a car Head end is lifted, and when the elongation of the piston rod of cylinder 3 reaches range, thick stick ontology of keeping off a car is fully opened；It needs to close and keep off a car When thick stick ontology 2, the piston rod of cylinder 3 is retracted by operation control box, drives negative side of the movable pulley 7 to thick stick ontology head end of keeping off a car To movement, wirerope 10 is released, and at the same time, the right end for thick stick ontology 2 of keeping off a car is rotated around the bottom end of fixed plate 1, so that keeping off a car The head end of thick stick ontology moves downward, and when the piston rod of cylinder 3 is fully retracted, thick stick ontology of keeping off a car is in the completely closed state.

When wirerope 10 is elongated and cannot return to initial position, the position by adjusting mounting base 8 can make to keep off a car Thick stick ontology 2 sets back；Since thick stick ontology of keeping off a car is normally off, when thick stick ontology of keeping off a car is closed, the piston rod of cylinder is contracting The state of returning, is effectively guaranteed the service life of cylinder.

The above is only the preferred embodiment of the present invention, rather than limitations of the present invention, is not departing from this In the case where the spirit and scope of utility model, all equivalent changes and modifications made according to the patent scope of the utility model, Should all it belong within the scope of patent protection of the utility model.
