Abstract
The utility model provides a detachment tool for a coal cutter rocker arm connecting pin shaft. The detachment tool for the coal cutter rocker arm connecting pin shaft comprises a stud, wherein one end of the stud is connected with a lifting jack, the lifting jack is provided with a liquid injection port and an oil injection port, the liquid injection port is connected with a liquid injection gun barrel, and the oil injection port is connected with an oil pressure pump. The detachment tool for the coal cutter rocker arm connecting pin shaft draws the pin shaft out through the supporting force of the hydraulic lifting jack based on the principle of pressure of liquid, achieves the purpose of rapid detachment, improves work efficiency, and achieves rapid, effective and safe operation.
Description
Technical field
The utility model relates to structural establishment technical field, is specifically related to the removal tool that a kind of rocker arm of coal mining machine connects bearing pin.
Background technology
Rocker arm of coal mining machine connect bearing pin due to its service time length can cause faying face corrosion or the bearing pin distortion of parts, it is more difficult to remove.Existing rocker arm of coal mining machine connects adopt manually of dismounting of bearing pin more and directly removes, and there is no specific purpose tool, when removed in down-hole, to use manpower to draw hammer operation mostly, use pull bar, wire drawing will draw hammer to be fixedly connected on bearing pin, use manpower to pull frequently hammer, utilize the impulsive contact force that draws hammer, to realize the object that bearing pin is extracted out.More than rocker arm of coal mining machine connection bearing pin of manual demolition needs time 2 h, more consuming time; When manpower can not be removed, must use oxygen-acetylene to cut, at this moment must be from ground blanking, beat to be transported to and remove place, the man-hour, the labour that need are more, and a general bearing pin need spend more than 15 hours, and operation is numerous and diverse, there is larger potential safety hazard.
Utility model content
The utility model will solve above-mentioned deficiency exactly, and the removal tool that provides a kind of rocker arm of coal mining machine to connect bearing pin realizes effective, the fast dismantling of silo shearer rocking arm connection bearing pin are removed.
In order to reach above-mentioned effect, the utility model provides rocker arm of coal mining machine to connect the removal tool of bearing pin, comprises stud, and one end of stud is connected with jack; Described jack is provided with liquid injection port and pouring orifice, and described liquid injection port is connected with fluid injection gun barrel, and described pouring orifice is connected with oil pressure pump.
Further, described stud is set in pressure-bearing frame.
Further, described pressure-bearing frame is the shaped as frame that upper end open, three sidewalls connect together, and the sidewall in the middle of it is provided with installing hole, and described stud is located in installing hole.
This removal tool is first pressure-bearing frame to be propped up to bearing pin periphery coal-winning machine shell plane to be torn open while using, and stud is through the installing hole on pressure-bearing frame, and its one end is fixed on bearing pin to be removed, full on silking; The other end is fixed on jack, full on silking, and uses spanner that stud is screwed, and by jack suspention and bearing pin same level line, connects fluid injection gun barrel and carries out fluid injection supercharging in from liquid injection port to jack, utilizes the outside pulling force of jack that bearing pin is pulled out; After bearing pin is removed, use oil pressure pump to connect pouring orifice, utilize oil pressure that jack is shunk to playback.Activity duration needs at most 30 minutes time from tool assemble to extracting bearing pin out.
The utility model is to utilize the pressure principle of liquid to replace former impact of drawing hammer, by being newly provided with the support force transmission of the hydraulic jack of pouring orifice, bearing pin is extracted out to the object of removing to reach fast dismantling.
Using after this removal tool, make dismounting hinge pin success rate reach 100%, improved greatly operating efficiency, is 3-5 times of original operating efficiency.Reduce maintenance personal's labour intensity simultaneously, saved a large amount of manpower and materials, realized quick, effective, safe operation, for maintenance personal's safety provides powerful guarantee, thereby created considerable benefit.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model is used state diagram;
In figure: 1-stud, 2-pressure-bearing frame, 3-jack, 3-1 liquid injection port, 3-2 pouring orifice, 4-coal-winning machine shell, 5-bearing pin, 6-fluid injection gun barrel, 7-oil pressure pump.
The specific embodiment
As shown in Figure 1, rocker arm of coal mining machine connects the removal tool of bearing pin, comprises the stud 1 being set in pressure-bearing frame 2, and one end of stud 1 is connected with jack 3; Described jack 3 is provided with liquid injection port 3-1 and pouring orifice 3-2, and described liquid injection port 3-1 is connected with fluid injection gun barrel 6, and described pouring orifice 3-2 is connected with oil pressure pump 7.
Further, the shaped as frame that described pressure-bearing frame 2 connects together for upper end open, three sidewalls, the sidewall in the middle of it is provided with installing hole, and described stud 1 is located in installing hole.
During use, pressure-bearing frame 2 is propped up to bearing pin to be torn open 5 periphery coal-winning machine shell 4 planes, stud 1 one end is fixed on bearing pin 5 to be removed, the other end is fixed on jack 3, and use spanner that stud 1 is screwed, by jack 3 suspention and bearing pin 5 same level lines, connect fluid injection gun barrel 6 and carry out fluid injection supercharging in from liquid injection port 3-1 to jack 3, utilize the outside pulling force of jack 3 that bearing pin 5 is pulled out; After bearing pin is removed, use oil pressure pump 7 to connect pouring orifice 3-2, utilize oil pressure that jack 3 is shunk to playback, realize the object that fast dismantling removes.
Above embodiment is not limited only to protection domain of the present utility model, all based on basic thought of the present utility model, modify or change all belong to protection domain of the present utility model.
