Abstract
The utility model discloses a coal cutter body connecting structure, comprising a left traction section, a right traction section, an intermediate box and a connecting plate, wherein the left traction section and the right traction section are connected through the intermediate box; the left traction section, the intermediate box and the right traction section are sequentially connected and then a plurality of grooves are formed in the connected joints on the surfaces; connecting plates matched with the grooves in size are arranged inside the grooves; the left traction section, the right traction section and the intermediate box are fixedly connected by the connecting plate through a fixed part. The device can bear relatively large tangential force and pulling force, and is not easy to lose efficacy, firm and reliable to connect, not easy to play, simple in structure, convenient to dismantle and install, easy to process, relatively low in cost, and beneficial to use in a pit.
Description
Technical field
The utility model relates to a kind of coal-winning machine body connection structure.
Background technology
Coal-winning machine is the nucleus equipment of fully-mechanized mining working, and itself and hydraulic support, scratch board conveyor support the use.Coal-winning machine work under bad environment, the course of work is hit larger, and fuselage connects the insecure mechanical accident that very easily occurs, and causes coal-winning machine work to be interrupted, and brings economic loss to user.
Traditional fuselage connection is mostly adopted long draw fuselage is linked together, and strains by hydraulic nut, and this mode has some shortcomings part: the one, and cost is high, long draw complex manufacturing, hydraulic nut purchase cost is high; The 2nd, dismounting inconvenience, conditions down-hole is limited, and long draw size is large, is unfavorable for dismounting, and the dismounting of hydraulic nut needs special instrument; The 3rd, easy inefficacy, this connected mode stretching resistance is stronger, but anti-tangential force a little less than, easily cut off.
Utility model content
The purpose of this utility model is that providing a kind of for the deficiencies in the prior art enough bears larger tangential force and pull to power, be difficult for losing efficacy, be connected firmly, reliably, be difficult for play, simple in structure, easy accessibility, be easy to processing, cost is lower, is beneficial to the coal-winning machine body connection structure that down-hole is used.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of coal-winning machine body connection structure, comprise left tractive unit, right tractive unit, intermediate box and junction plate, described left tractive unit and right tractive unit interconnect by described intermediate box, the seam crossing connecting on its surface after described left tractive unit, intermediate box are connected successively with right tractive unit is provided with multiple grooves, the junction plate matching with described groove size is installed in described groove, and described junction plate is fixedly connected with right tractive unit left tractive unit by fixture with intermediate box.
Described fixture is bolt and pad.
The seam crossing that described left tractive unit, intermediate box and right tractive unit are connected is provided with two grooves, and described groove is " work " font.
Owing to adopting such scheme, the utlity model has following advantage:
1, the junction plate that the utility model adopts can not only link together left tractive unit, right tractive unit and intermediate box, and can bear larger tangential force and pull to power, is difficult for losing efficacy.
2, junction plate of the present utility model is bolted on fuselage, is connected firmly, reliably, is difficult for play.
3, simple in structure, the easy accessibility of fuselage connection of the present utility model, be easy to processing, cost is lower, be beneficial to down-hole and use.
Brief description of the drawings
Fig. 1 is the use state diagram after the utility model connects for coal-winning machine fuselage.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, further describe the detailed description of the invention of this patent.
As shown in Figure 1, a kind of coal-winning machine body connection structure, is that left tractive unit 1 is connected respectively to intermediate box 2 with right tractive unit 3 for the effect of the fuselage connection on coal mining machine in full-mechanized mining face, reliable to ensure the connection of coal-winning machine fuselage.
As shown in Figure 2, mill out respectively groove, and be drilled with screwed hole at left tractive unit 1, right tractive unit 3 with intermediate box 2 places of combining, to place junction plate, two junction plates are respectively put in each junction, reliable to ensure connection.
As shown in Figure 3, coal-winning machine body connection structure primary structure is made up of junction plate 6, and junction plate 6 is arranged in groove, and fixing by bolt 4 and pad 5.
Claims (3)
1. a coal-winning machine body connection structure, comprise left tractive unit, right tractive unit, intermediate box and junction plate, described left tractive unit and right tractive unit interconnect by described intermediate box, it is characterized in that: the seam crossing connecting on its surface after described left tractive unit, intermediate box are connected successively with right tractive unit is provided with multiple grooves, the junction plate matching with described groove size is installed in described groove, and described junction plate is fixedly connected with right tractive unit left tractive unit by fixture with intermediate box.
2. coal-winning machine body connection structure according to claim 1, is characterized in that: described fixture is bolt and pad.
