Abstract
The utility model provides a telescopic heading machine convenient for underground transportation, which aims to solve the ubiquitous problems of existing heavy high-power heading machines that bodies are overlarge in size, not detachable and not beneficial for underground transportation, and a cutting head is non-retractable. The telescopic heading machine is mainly characterized in that a cutting speed reducer box is connected with a retractable section of a cutting head by the aid of two hydraulic cylinders, a special water channel for high-pressure water is arranged on the cutting head, a shovel plate, a first conveyor, a connecting rod and a rear support are connected sequentially in a hinged manner to form a four-link mechanism, and a body is divided into a front body frame and a rear body frame from the middle. The telescopic heading machine has the advantages of convenience for underground transportation and installation and improvement of the utilization rate of an underground heading machine.
Description
Technical field
The utility model relates to the coal mine roadway development machine, is specially a kind ofly can carry out the total rock tunnelling, reduces the extension type development machine that pick loss, convey materials are convenient, be beneficial to the down-hole transportation and install simultaneously.
Background technology
At present, tunnelling machine can only cut the rock of compressive strength≤10, and when exceeding this scope, method commonly used adopts the big gun pick exactly.Big gun pick operation not only has high risk is also wasted the plenty of time simultaneously, influences drivage efficiency, and the numerous and confused exploitation of each R﹠D institution can be cut the development machine of compressive strength＞10 rocks thus.Yet the high-power development machine ubiquity of existing heavy type body is oversize and non-dismountable, installs and is unfavorable for the down-hole transportation during last well servicing going into the well, and the pick loss is too fast during cutting hard rock simultaneously, shortcomings such as convey materials inconvenience; Secondly, the cutting speed reducer casing is connected with cutting head by cantilever segment, makes not flexible of cutting head.To sum up these shortcomings make some colliery even abandon the machinery driving.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of extension type development machine of being convenient to the down-hole transportation.
The purpose of this utility model is achieved in that it comprises cutting head telescopic section, cutting speed reducer, body, back support, shovel board and first transporter, is characterized in that:
(1), the cutting speed reducer casing is connected with the cutting head telescopic section by two hydraulic cylinders, making cutting head is extension type, is more conducive to cutting hard rock;
(2), the special-purpose water channel of water under high pressure is set, utilize the auxiliary cutting of water under high pressure at cutting head;
(3), shovel board, first transporter, connecting rod support with the back and be connected successively, connected mode is hinged, constitutes quadric chain, makes the double-chain length variation very little, convey materials is more convenient.
(4), body is divided into two from the centre, be divided into forward and backward body frame, forward and backward body frame is connected with bolt by dumbbell pin, and it can be dismantled, and is convenient to the down-hole transportation like this and installs.
Compared with prior art, the beneficial effects of the utility model are: body can decompose, having the extension type cutting part comes effective cutting hard rock and can reduce the pick loss by the auxiliary cutting of water under high pressure, convey materials is convenient, the heavy development machine that is beneficial to the down-hole transportation and installs, thereby the minimizing cost, the utilization rate of raising down-hole development machine.

The specific embodiment
Referring to Fig. 1, the utility model comprises cutting head telescopic section 1, shovel board 2, cutting speed reducer casing 3, body 5, back support 6, first transporter 8, it is characterized in that:
Referring to Fig. 2, cutting speed reducer casing 3 is connected with cutting head telescopic section 1 by two hydraulic cylinders 4, promptly the cylinder body of two hydraulic cylinders is fixed on the cutting speed reducer casing, and the piston rod of hydraulic cylinder is fixed on the cutting head telescopic section, making cutting head is extension type, is beneficial to cutting hard rock;
Referring to Fig. 3, at cutting head the special-purpose water channel 11 of water under high pressure is set, utilize the auxiliary cutting of water under high pressure, specifically be cutting part from motor tail end 7 to main shaft the coaxial circular hole of 12 head end segmental machining, seamless steel pipe 9 that can withstand voltagely be higher than 80MPa in circular hole, steel pipe and circular hole are tight fit, ring supports with steel pipe 9 assembling conducts in the bearing 8, the seamless steel pipe water inlet end is connected with high-pressure hydraulic pump, the special-purpose water channel 11 of delivery port and cutting head, nozzle 13 connects successively, to design attitude, for solving the water under high pressure sealing, main shaft 12 adopts ringfeder 10 types of attachment with cutting head 1 to water under high pressure by nozzle ejection;
Referring to Fig. 4,5, shovel board 2 and first transporter, 14 hinged 15, the first transporters and connecting rod 21 hinged 20, it is hinged 22 that connecting rod 21 and back are supported, and shovel board 2 tail ends also hinged 16 are on body, and they constitute quadric chain, it is very little that double-chain length is changed, and convey materials is more convenient.
Referring to Fig. 6, body is divided into two from the centre, be divided into forward and backward body frame 17 and 19, forward and backward body frame is connected with bolt by dumbbell pin 18, is convenient to down-hole transportation and installation like this.
