Abstract
The utility model is specially a kind of fully-mechanized mining working disintegration face end support pin pulling out device, and existing to pull pin when solving the disintegration of existing face end support wastes time and energy and the problem of inefficiency.Fully-mechanized mining working disintegration face end support pin pulling out device, comprise pin body, pin body right-hand member axle center is installed with the leading screw be threaded, cannulated sleeve is provided with on the right side of pin body, cannulated sleeve right-hand member is fixed with the disk be through on leading screw, and cover has the Hollow hydraulic cylinder be positioned on the right side of disk on leading screw, the right-hand member of Hollow hydraulic cylinder is provided with baffle plate, is provided with the locking nut be screwed on leading screw on the right side of baffle plate.The utility model reasonable in design is reliable, and manually oil pump drives Hollow hydraulic cylinder to pull pin, powerful, while time saving and energy saving, alleviate labour intensity, and then effectively improve operating efficiency, there is simple, easy to process, the with low cost and advantage of use safety of structure.
Description
Technical field
The utility model relates to underground mine use pin pulling out device, is specially a kind of fully-mechanized mining working disintegration face end support pin pulling out device.
Background technology
After the operation of underground coal mine work plane completes, need carry out withdrawing of equipment, the while of with it, need disintegrate face end support.
The structure of existing pin pulling tool is that the other end overlaps a disk as baffle plate by overlapping a dumbbell shaped tup on a rhizoid thick stick, one end connecting pins of leading screw, and pin pulls out by the tup impingement baffles that moves about outward.
This mode Shortcomings part of pulling pin: one is inefficiency, sometimes because a pin pulls out not open, can affect whole equipment and withdraw progress; Two is that labour intensity is large, and during topping beam pin, go smoothly especially and lift trip hammer impingement baffles, operation is inconvenience very.
Summary of the invention
The utility model is wasted time and energy and the problem of inefficiency to exist to pull pin when solving the disintegration of existing face end support, provides a kind of fully-mechanized mining working disintegration face end support pin pulling out device.
The utility model adopts following technical scheme to realize: fully-mechanized mining working disintegration face end support pin pulling out device, comprise pin body, pin body right-hand member axle center is installed with the leading screw be threaded, cannulated sleeve is provided with on the right side of pin body, cannulated sleeve right-hand member is fixed with the disk be through on leading screw, and cover has the Hollow hydraulic cylinder be positioned on the right side of disk on leading screw, the right-hand member of Hollow hydraulic cylinder is provided with baffle plate, is provided with the locking nut be screwed on leading screw on the right side of baffle plate.
When carrying out pulling pin operation, operation hand oil pump drives Hollow hydraulic cylinder to extend, and Hollow hydraulic cylinder for fulcrum with the disk of hollow cylinder, drives baffle plate, locking nut and leading screw to move right, and then pulled out outward by pin body; When Hollow hydraulic cylinder is without stroke, post of being lived by oil cylinder is retracted, and pads with packing ring, then continues to drive Hollow hydraulic cylinder toward the sub-body of outer drawing pin, and till being extracted by pin body, existing to pull pin when overcoming the disintegration of existing face end support wastes time and energy and the problem of inefficiency.
The utility model reasonable in design is reliable, and manually oil pump drives Hollow hydraulic cylinder to pull pin, powerful, while time saving and energy saving, alleviate labour intensity, and then effectively improve operating efficiency, there is simple, easy to process, the with low cost and advantage of use safety of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-pin body, 2-leading screw, 3-cannulated sleeve, 4-disk, 5-Hollow hydraulic cylinder, 6-baffle plate, 7-locking nut.
Detailed description of the invention
Fully-mechanized mining working disintegration face end support pin pulling out device, comprise pin body 1, pin body 1 right-hand member axle center is installed with the leading screw 2 be threaded, cannulated sleeve 3 is provided with on the right side of pin body 1, cannulated sleeve 3 right-hand member is fixed with the disk 4 be through on leading screw 2, and cover has the Hollow hydraulic cylinder 5 be positioned on the right side of disk 4 on leading screw 2, the right-hand member of Hollow hydraulic cylinder 5 is provided with baffle plate 6, is provided with the locking nut 7 be screwed on leading screw 2 on the right side of baffle plate 6.
