Abstract
The utility model relates to a disassembly and assembly device for screw bolts, in particular to a hydraulic disassembly and assembly machine for screw bolts, comprising a machine frame, a hydraulic motor which is fixed on the rear panel of the machine frame, a transmission shaft which is sheathed with the end of the output shaft of the hydraulic motor and a shaft hole which is matched with the end of the output shaft of the hydraulic motor and is opened on the rear end of the transmission shaft. The front part of the transmission shaft is supported on a bearing which is positioned by a bearing sleeve which is fixed by the front panel of the machine frame. The front end of the transmission shaft is made into a shape of a screw nut and is extended from the shaft hole on the front panel of the machine frame. The hydraulic disassembly and assembly machine for screw bolts makes use of the pump station hydraulic system of a comprehensive face for a mine as the power source of the hydraulic motor. So the looseness, disassembly and assembly of the screw bolts can be realized conveniently, quickly and easily. The utility model provides a special disassembly and assembly device for screw bolts for the downhole, has the advantages of simple structure, safety, reliability, convenient operation and is suitable for each place with hydraulic power, in particular to the downhole with a gaseous mine. The problem of out of explosion does not exist. The utility model is convenient for moving and has better safety.
Description
Technical field
The utility model relates to the bolt disassembly device, is specially a kind of hydraulic bolt changer.
Background technology
Along with the raising of mine machinery degree and plant equipment to maximization, high strength, high durable development, the dismounting of plant equipment bolt has become highly intensive labour, and dismantling device also rests in the original sleeve pipe pressure lever type dismounting.Mine downhole production humid environment is abominable, causes bolt corrosion, the dismounting difficulty, and the intensity of artificial dismounting and workload strengthen, equipment removal of home cycle lengthening; Operation easier increases in the process of dismounting because corrosion causes, and security is not high yet, and is unfavorable to personal safety.In order to solve the dismounting problem, prior art has pneumatic, electronic, pneumatic dismantling device, and use very extensive; Yet above instrument only is useful under the non-mine and uses, and down-hole, instrument explosion-proof, high pulling torque are blank always.
Summary of the invention
The utility model is not exclusively used in the problem of the bolt disassembly device under the mine at prior art, and a kind of hydraulic bolt changer is provided.
The utility model is to adopt following technical scheme to realize: the hydraulic bolt changer, comprise frame, on the rear board of frame, be fixed with hydraulic motor, the hydraulic motor output shaft end is with power transmission shaft, the rear end of power transmission shaft has the axis hole that cooperates with the hydraulic motor output shaft end, the front support of power transmission shaft by with the bearing of the fixing bearing holder (housing, cover) location of frame front panel on, the leading section of power transmission shaft makes nut type and the axis hole from the frame front panel stretches out.When using, this hydraulic bolt changer need supporting two ends to have the quarter butt in the hole that cooperates with nut, this hydraulic bolt changer is moved to the bolt place that needs dismounting, with the borehole jack of quarter butt one end on the nut type spindle nose of changer, the other end is enclosed within on the bolt and nut that needs dismounting, makes the hydraulic motor forward and backward can realize the dismounting of bolt.
Hydraulic bolt changer described in the utility model utilizes the power source of mine fully-mechanized mining working pumping plant hydraulic system as hydraulic motor, can convenient, fast, easily realize loosening, the dismounting of bolt, and a kind of bolt disassembly device of special use is provided for the down-hole.Use this changer to increase work efficiency greatly, reduce man-hour, save time, laborsaving, efficient can improve 20 times, reduces underground equipment moving time and expense greatly.This changer structure is simple especially, the security reliability height, and personnel operation is convenient, is applicable to each place of hydraulic power, especially has the down-hole of gaseous mine to use, and neither exists and loses quick-fried problem, is convenient to again move, and security is better.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 cuts open figure for the B-B of Fig. 1 bows;
The specific embodiment
The hydraulic bolt changer, comprise frame 1, on the rear board of frame, be fixed with hydraulic motor 2, the hydraulic motor output shaft end is with power transmission shaft 3, the rear end of power transmission shaft has the axis hole that cooperates with the hydraulic motor output shaft end, the front support of power transmission shaft by with the bearing 5 of fixing bearing holder (housing, cover) 4 location of frame 1 front panel on, the leading section of power transmission shaft makes nut type and the axis hole from the frame front panel stretches out.
The axis hole flat key or the spline fitted of hydraulic motor output shaft end and power transmission shaft rear end.
On the side panel of frame 1, be fixed with triangular support bracket 6.Triangular support bracket can increase the stability of strutting system of frame, prevents toppling at assembling-disassembling bolt process mid frame.
The front end of power transmission shaft 3 has the endoporus 7 that communicates with its rear end axis hole.When needs dismounting hydraulic motor and when being difficult to pull down, can in this endoporus, insert a bar, the hydraulic motor output shaft end is disclosed in the axis hole of power transmission shaft rear end.
When this changer uses in the down-hole, with the emulsion in the fully-mechanized mining working pumping plant hydraulic system of down-hole as the pressure liquid that drives hydraulic motor, and with emulsion pump as pressure source.
