Description
Technical Field
The utility model relates to a hydraulic support base hinge pin axle pulling pin frock.
Background
The hydraulic support is one of main devices for coal mining, and directly influences the safety support of a roadway. The hinge pin shaft of the base is used as a quick-wear part and often needs to be replaced, and the hinge pin shaft also often needs to be detached firstly when the hydraulic support is detached. The pin shaft has small fit clearance, the underground environment is moist and is easy to rust, and the operation space is limited, so that the disassembly difficulty is increased, the efficiency is low, and a plurality of tools are difficult to transfer underground and have poor flexibility.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the deficiencies of the prior art, providing a hydraulic support base hinge pin pulling tool with simple structure, convenient use, portability and easy disassembly.
The utility model comprises a base, a guide sleeve, a drawing shaft, a bolt, a small pin shaft, a pressure bar seat, a bolt and a switch type magnetic seat; the base is tightly attached to the side face of the bracket base to play a supporting role, a groove is formed in the base to keep away from a pin baffle on the base, and a through hole is formed in the base to be fixed (in transition fit) with the guide sleeve; the guide sleeve is fixed on the base, and when the hinge pin shaft is pulled out, the direction of the hinge pin shaft is fixed and can be disassembled and replaced; one side of the drawing shaft is fixed with the hinge pin shaft through threaded connection, and the other side of the drawing shaft is connected with the pressing rod through a bolt; the bolt is inserted into the drawing shaft, and one side of the bolt is hinged with the pressure lever; the small pin shafts are divided into two parts, one part is used for hinging the bolt and the pressure rod, and the other part is used for hinging the pressure rod and the pressure rod seat; one side of the pressure lever is hinged with the bolt, the middle of the pressure lever is hinged with the pressure lever seat, and the drawing shaft and the hinge pin shaft are pulled out together according to the lever principle by pressing the other side of the pressure lever; the pressure rod seat is formed by fixing two rows of high-strength steel plates on the base, placing the pressure rod in the middle of the pressure rod seat, and hinging the pressure rod with the pressure rod, wherein a plurality of equidistant hinging holes are formed in the pressure rod seat, and the fulcrum of the pressure rod can be continuously adjusted by continuously changing the hinging position, so that the hinging pin shaft can be finally pulled out; the switch type magnetic base is connected with the base through the bolt, the magnetic force can be turned off at any time through the switch, and the whole tool is convenient to disassemble.
During the use, at first will draw in the axis screwed one side twist hinge pin (hinge pin is from taking the screw hole), penetrate the uide bushing on the base with drawing the axle centering, unscrew magnetic base switch, let whole base fix on the base, will draw the axle other end through penetrating the bolt, articulate bolt and depression bar with the little round pin axle, then articulate depression bar and depression bar seat with the little round pin axle. And at the moment, the other end of the pressure rod is pressurized, the hinge pin shaft is pulled out through the lever principle, after the limit is reached, the hinge position point of the pressure rod and the pressure rod seat is replaced, the pressure is continuously exerted on the other end of the pressure rod, and the process is repeated continuously until the hinge pin shaft is pulled out.
The utility model discloses utilize lever principle, constantly adjust the fulcrum, constantly extract pull pin and hinge pin axle together through the bolt, can be used to the hinge pin axle of the various model hydraulic support bases of various occasions, simple structure and dismantlement convenient to use, the power consumption, portable makes things convenient for the operation anytime and anywhere.
Drawings
FIG. 1 is a schematic view of the assembly structure of the present invention;
in the figure: 1. the device comprises a support base, 2 hinge pin shafts, 3 pin baffle plates, 4 bases, 5 guide sleeves, 6 drawing shafts, 7 bolts, 8 small pin shafts, 9 pressing rods, 10 pressing rod seats, 11 bolts and 12 switch type magnetic force seats.
Detailed Description
The base 4 is tightly attached to the side surface of the bracket base 1, a groove is formed on the base to keep away from the pin baffle 3 on the base, and a through hole is formed to be fixed with the guide sleeve 5; the guide sleeve 5 is fixed on the base 4; one side of the drawing shaft 6 is fixed with the hinge pin shaft 2 through threaded connection, and the other side of the drawing shaft is connected with the pressing rod 9 through a bolt 7; the bolt 7 is inserted into the drawing shaft 6, and one side of the bolt is hinged with the pressure lever 9; the number of the small pin shafts 8 is two, one small pin shaft is hinged with a pressure lever 9 through a bolt 7, and the other small pin shaft is hinged with a pressure lever seat 10 through the pressure lever 9; one side of the pressure lever 9 is hinged with the bolt 7, and the middle part is hinged with the pressure lever seat 10; the pressure rod seat 10 is two rows of high-strength steel plates fixed on the base 4, a pressure rod 9 is placed in the middle and hinged with the pressure rod 9, and a plurality of hinge holes with equal intervals are formed in the pressure rod seat; the switch type magnetic base 12 is connected with the base 4 through a bolt 11.
Will draw in 1 screwed one side of axle to twist articulated round pin axle 2 (articulated round pin axle 2 is from threaded hole), penetrate the uide bushing 5 on the base 4 with drawing 6 centering of axle, unscrew 12 switches on the magnetic base, let whole base 4 fix on support base 1, will draw the other end of axle 6 through penetrating bolt 7, articulate bolt 7 and depression bar 9 with little round pin axle 8, then articulate depression bar 9 and depression bar seat 10 with another little round pin axle 8. At the moment, the other end of the pressure rod 9 is pressurized, the hinge pin shaft 2 is pulled out through the lever principle, after the limit is reached, the hinge position points of the pressure rod 9 and the pressure rod seat 10 are replaced, the pressure is continuously exerted on the other end of the pressure rod 9, the process is repeated continuously until the hinge pin shaft 2 is pulled out, and one complete operation is finished.
