Abstract
The utility model discloses a hydraulic anchor-drawing device for recycling anchors, which belongs to coal mine anchor rod-drawing tools, and comprises a hydraulic oil cylinder, wherein, a steel pipe is welded at the front end of the cylinder body of the hydraulic oil cylinder; a circular disc which is used for enlarging thrust surface area is welded at the front end of the steel pipe; and an anchor-drawing device square head which is used for connecting the piston of the hydraulic oil cylinder with an anchor rod head is connected with the front end of the piston of the hydraulic oil cylinder. The working principle and the using method are as follows: firstly, sticking out the piston of the anchor-drawing device oil cylinder, connecting the piston with the anchor rod head through the anchor-drawing device square head, propping the circular disc of the front end of the anchor-drawing device against a roadside to be a fulcrum, then, operating a reversal valve, withdrawing the oil cylinder piston, and drawing the anchor rod out. The anchor-drawing device has the beneficial effects of simple structure and convenient use.
Description
Technical field
The utility model relates to the bar instrument that weighs anchor that the colliery is used, and specifically is to be used to reclaim a kind of hydraulic pressure that anchor pole uses device that weighs anchor.
Technical background
The tunnel be the fully-mechanized mining working of bolting with wire mesh when back production, the anchor pole of work plane lane group is bigger to the back production influence, main influence is: coal mining machine roller cuts anchor pole, often damages pick; Anchor pole enters the coal streaming system, and scratch board conveyor, conveyor are had considerable influence, stops up The Small Well easily, and coal separation is had certain influence.To so far, the special tool of anchor pole is not all extracted in national colliery, generally all is directly to cut anchor pole with coal-winning machine.
Summary of the invention
The purpose of this utility model provides a kind of hydraulic pressure device that weighs anchor, and is used to solve coal mining machine roller and directly cuts the anchor pole problem of helping on the twice, in advance anchor pole is extracted.
The utility model is realized with following technical scheme: a kind of hydraulic pressure device that weighs anchor, it is characterized in that: it comprises a hydraulic jack, cylinder body front end at hydraulic jack is welded with a steel pipe, steel pipe front end welding one is used to increase the disk of lifting surface area, and the piston nose of hydraulic jack connects the device square toes that weigh anchor that are used for being connected with the anchor pole head.
Operating principle and using method are: the device oil cylinder piston that at first will weigh anchor stretches out, and connects with weigh anchor device square toes and anchor pole head, is pressed on the lane with the device front end disk that weighs anchor and helps as fulcrum, and is reversing valve operated then, receives oil cylinder piston, and anchor pole is extracted.
The beneficial effects of the utility model are: simple in structure, easy to use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model structural representation.
Among the figure: 1, hydraulic jack, 1-1, piston, 1-2, cylinder body, 2, steel pipe, 3, disk, 4, the device square toes that weigh anchor, 5, nut, 6, screw, 7, anchor pole.
The specific embodiment
As shown in drawings, the hydraulic pressure device that weighs anchor has a hydraulic jack 1, and the oil cylinder piston diameter that hydraulic jack 1 is selected for use in the present embodiment is 60mm, and the piston extension elongation is 600mm.At steel pipe 2 that length is 600mm of front end welding of cylinder body 1-2, the steel pipe front end welds a disk 3 and is used to increase lifting surface area; The front end of piston 1-1 welds a M24 the screw 6 and device square toes 4 that weigh anchor and is connected, and fixes a nut 5 in the front portion of the device square toes 4 that weigh anchor and is used for fixedlying connected with the head of anchor pole 7.
The piston 1-1 of device oil cylinder 1 of at first will weighing anchor during use stretches out, and is connected with the head of anchor pole 7 and fixes with nut 5 with the device square toes 4 that weigh anchor, and is against the lane with the disk 3 of the device front end that weighs anchor and helps as fulcrum.Receive oil cylinder piston 1-1, anchor pole can be extracted.
