Abstract
The utility model discloses a rectangular full-face continuous miner, which comprises a headstock. A power mechanism is mounted inside the headstock. A support is fixed at the front end of the headstock. A plurality of tiers of heading rollers are transversely mounted at the front end of the headstock. The extension length of each lower heading roller is larger than that of the corresponding upper heading roller. Each heading roller is provided with cutting teeth. The heading rollers are all driven by a hydraulic motor. In addition, a scraper conveyor is mounted in the middle of the bottom of the headstock. Full-face one-step forming of a rectangular roadway is achieved by using the rectangular full-face continuous miner. The rectangular full-face continuous miner is especially applicable to mining in cone roadways and has the advantages of full-face heading and one-step forming. The rectangular full-face continuous miner is effective in roadway forming, and great convenience is brought to late roadway supporting. The rectangular full-face continuous miner is available for continuous mining, allows for simultaneous heading and supporting without mutual interference, and has the functions of heading, discharging and supporting. By using the rectangular full-face continuous miner, production efficiency is improved greatly.
Description
Technical field:
The utility model relates to coal road full advance technology, is specifically related to the full section of a kind of rectangle and connects the machine of adopting.
Background technology:
At present, existing coal mine roadway development machine can not be realized one-shot forming to the tunnel exploitation, needs the repeated multiple times exploitation, and operating efficiency is lower, and the laneway molding effect is bad, for the later stage supporting is made troubles.
The utility model content:
The utility model proposes the full section of a kind of rectangle and connects the machine of adopting to the problem and shortage that exists in the present prior art.
The technical scheme that the utility model adopted: the full section of a kind of rectangle connects the machine of adopting; Comprise headstock, boring mechanism and drag conveyor, wherein drag conveyor is positioned at the headstock bottom, and the headstock front end is provided with boring mechanism; Vertically be fixed with girder in the headstock; This girder is delayed time to the headstock rear side, and the both sides of said girder are respectively arranged with the support boots, and the support boots comprise transversal stretching oil cylinder and gripper shoe; But longitudinal sliding motion cooperates between the root of transversal stretching oil cylinder and the girder; Gripper shoe is vertically fixed on the expansion link end of telescopic oil cylinder, on gripper shoe root or telescopic oil cylinder sidewall, is hinged with vertical propelling oil cylinder simultaneously, and this vertically advances the other end of oil cylinder to be hinged on the headstock rear wall.
The terminal both sides of girder are vertically fixed with hoist cylinder respectively.
Boring mechanism is to be fixed with gripper shoe in the headstock front side; Be horizontally installed with multilayer driving cylinder on each gripper shoe successively; Lower floor's driving cylinder extension elongation is tunneled the extension elongation of cylinder successively greater than the upper strata; The whole driving conical surface that forms is equipped with pick on each roller periphery, and each roller is by the hydraulic motor drive.
The headstock two bottom sides is equipped with being cut the setting gauge that coal is pulled over to drag conveyor.Setting gauge is dialled in the coal under the roller cutting in the drag conveyor, is transported by drag conveyor.
When roller tunneled forward, support boots oil cylinder stretched out gripper shoe stretching tunnel sidewall; The propelling oil cylinder that install support boots side stretches out, and girder is pushed ahead, behind the propelling certain distance; The girder support cylinder stretches out and supports ground, and support boots oil cylinder is regained, and gripper shoe breaks away from the tunnel sidewall; The propelling oil cylinder shrinks, and the support boots certain distance that advances supports the boots oil cylinder then and stretches out and carry out second cyclic process.
The good effect of the utility model: the utility model is a kind of novel coal road full face tunnel boring machine; Utilize hoist cylinder and support boots to cooperate and realize that circulation moves ahead and headwork; Reasonable in design has realized the full section one-shot forming of rectangular shaped roadways, is particularly useful for the exploitation of coal mine roadway; Has full advance, one-time formed advantage.Laneway molding is effective, and high efficiency is for later stage roadway support provides great convenience.This equipment can tunnel continuously.And realize tunneling and do not disturb mutually simultaneously, realized the function that driving, discharge, supporting are carried out simultaneously, greatly improved production efficiency with supporting.
Description of drawings:
Fig. 1 is the utility model side structure sketch map;
Fig. 2 is the plan structure sketch map of Fig. 1.
Label among the figure: 1 for driving cylinder 2 is that headstock 3 is drag conveyor for girder 4 for the gripper shoe 5 that supports boots, and 6 is slideway, and 7 is the transversal stretching oil cylinder, and 8 is vertically to advance oil cylinder, and 9 is hoist cylinder, and 10 is setting gauge, and 11 is the cylinder gripper shoe.
The specific embodiment:
Referring to Fig. 1 and Fig. 2, the full section of this rectangle connects the machine of adopting and comprises headstock and parts such as, driving cylinder and drag conveyor.Wherein vertically be fixed with girder 3 in the headstock 2, this girder is delayed time to the headstock rear side.
The headstock front side is fixed with gripper shoe 11, is horizontally installed with multilayer driving cylinder 1 on each gripper shoe successively, and lower floor's driving cylinder extension elongation is successively greater than the extension elongation of upper strata driving cylinder, and integral body forms the driving conical surface.On each roller periphery pick is housed, each roller is by the hydraulic motor drive.
The both sides of said girder 3 are respectively arranged with the support boots, and the support boots comprise transversal stretching oil cylinder 7 and gripper shoe 4, between the root of transversal stretching oil cylinder 7 and the girder 3 slideway are set, and are slidingly matched between the two.Gripper shoe 4 is vertically fixed on the expansion link end of telescopic oil cylinder 7.Root in gripper shoe 3 is hinged with vertical propelling oil cylinder 8 simultaneously, and this vertically advances the other end of oil cylinder 8 to be hinged on headstock 2 rear walls.
The terminal both sides of girder 3 are vertically fixed with hoist cylinder 9 respectively.Hoist cylinder 9 regular girders 3, keep excavation operation this moment, and after the gripper shoe 3 of two side stay boots held out against the two side, tunnel, hoist cylinder 9 lifted, and vertically advanced oil cylinder 8 to begin to stretch out, and was that headstock 2 is pushed ahead, and accomplished walking process.Periodic duty successively.
