Abstract
The utility model relates to an important component of coal mine roadheader, in particular to an anti-sideslip rear support at the tail end of the roadheader, which can solve the problem of lateral sliding of equipment tail when the roadheader cutting head cuts in transverse. Two supporting legs of the rear support of the utility model are braced in transverse at both sides of the roadheader center line, and the position of the supporting leg can be controlled alone according to the situation of the roadway bottom plate. The two supporting legs of the rear support of the utility model are respectively braced according to the revolving direction of the cutting head, so as to have anti-sideslip capability. The roadheader equipped with the rear support can greatly improve the excavation work efficiency, and greatly decrease the working strength of operators and increase the reliability.
Description
Technical field
The utility model relates to the vitals of coal mine roadway development machine, is specially a kind of anti-sideslip back supporting of development machine afterbody.
Background technology
At present, when excavation operation, cutterhead needs back and forth laterally cut, produces very big lateral thrust with development machine in the colliery, and existing back supporting construction weak point is: back two supporting legs of supporting are parallel with the development machine center line, the easy lateral sliding of equipment.So, be starved of the anti-back supporting of breakking away of a kind of energy, improve the operating efficiency of driving, reduce operator's labour intensity.
The utility model content
The purpose of this utility model is to provide a kind of development machine the anti-back supporting of breakking away, solve easy lateral sliding when having the development machine excavation operation now, cause problems such as equipment shakiness, this back supporting can increase substantially headwork efficient, greatly reduces operator's working strength.
The technical solution of the utility model is:
The utility model supports after development machine is provided, and supporting leg is in the both sides stull of development machine longitudinal centre line.
The beneficial effects of the utility model are:
1, two supporting legs of the anti-back supporting of breakking away of the utility model in development machine center line vertical plane to the both sides stull, raising equipment is prevented the sideslip ability, thereby improve the driving ability of equipment, equipment rear lateral sliding problem when solving the horizontal cut of cutting head of roadheader.
2, support two supporting legs behind the utility model according to the stull respectively of cutting arm gyratory directions, and can control the position of supporting leg separately according to the roadway floor situation.The development machine that adopts the utility model that this back supporting is installed can increase substantially headwork efficient, greatly reduces operator's working strength, improves reliability.
Description of drawings
The side-looking structure chart of supporting after Fig. 1 breaks away for the utility model is anti-.
The main TV structure figure of supporting after Fig. 2 breaks away for the utility model is anti-.
Among the figure, 1 support body; 2 hydraulic cylinders; 3 supporting legs; 4 support foots.
The specific embodiment
Shown in Fig. 1-2, the utility model is the anti-back supporting of breakking away of development machine, connect with hydraulic cylinder 2 between support body 1 and the supporting leg 3, support foot 4 under supporting leg 3, supporting leg with after to support longitudinal centre line A-A vertical.
The course of work of the present utility model is as follows:
(1) hydraulic cylinder 2 elongations, promoting supporting leg 3 changes downwards.
(2) support foot 4 contacts to earth, and supporting is ready for excavation operation after the jack-up.
(3) hydraulic cylinder 2 withdrawals, driving supporting leg 3 upwards changes.
(4) support foot 4 is liftoff, puts down the back supporting.
Claims (2)
1. the anti-back supporting of breakking away, it is characterized in that: two supporting legs of back supporting are provided with in the stull of development machine center line both sides.
2. according to the back supporting of the described anti-sideslip of claim 1, it is characterized in that: supporting leg connects with the support body of development machine by hydraulic cylinder.
