A self-moving type follow-up end bracket belongs to the technical field of fully mechanized mining of coal mine, and aims at providing an end bracket which has low labor intensity of workers, high work efficiency and good safety. The adopted technical scheme is as follows: a first top beam and a second top beam are connected together by a transition beam, a first push-and-pull oil cylinder is connected between the first top beam and the second top beam, a first bottom beam and a second bottom beam are connected by a second push-and-pull oil cylinder, the first top beam and the first bottom beam which are connected by a first link mechanism are arranged in parallel up and down, a first upright post oil cylinder and a second upright post oil cylinder are vertically installed between the first top beam and the first bottom beam, the second top beam and the second bottom beam which are connected by a second link mechanism are arranged in parallel up and down, a third upright post oil cylinder and a fourth upright post oil cylinder are vertically installed between the second top beam and the second bottom beam, and the transition beam is a stretching beam. The self-moving type follow-up end bracket is applied to the coal mine working face.
Description
Technical field
A kind of automatic moving type follower ends of the utility model head bracket belongs to the coal mine fully-mechanized mining equipment technical field.
Background technology
In recent years, along with the fully-mechanized mining technology rapid development, mining face under mine had obtained extensive utilization to the electrichydraulic control hydraulic support in the colliery; Improved the coal winning technology level greatly, but the coal-face termination still continues to use cross bar and adds individual prop and safeguard, in the feed of coal-winning machine end, pushing and sliding, move in the frame process; The roof timbering work of face end outlet is very loaded down with trivial details; Not only labour intensity is high, and waiting time of machine halt is long in the termination for coal-winning machine, and because the requirement of reinforcement support pattern and supporting distance longer in the face end; When making coal-winning machine whenever advance a transporter tail; All need the termination surfaceman to carry out the preparation in early stage, withdraw from hydraulic prop and metal rood beam near the rib side in advance, the machine cut that is beneficial to mine leads to the rib at transporter tail place.Such end support mode takes up room greatly, and complex operation causes working strength of workers high, inefficiency, and there is certain potential safety hazard in workman's personal safety during operation.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved provides that a kind of labor strength is low, high efficiency, face end support that safety is good.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of automatic moving type follower ends head bracket; First head piece and second head piece connect together through the transition crossbeam; Between first head piece and second head piece, be connected with first push cylinder; Be connected through second push cylinder with second cross member at first cross member, first head piece and first cross member that connect through first connecting rod mechanism are horizontally disposed with up and down, and the first column oil cylinder and the second column oil cylinder vertically are installed between first head piece and first cross member; Second head piece and second cross member that connect through second connecting rod mechanism are horizontally disposed with up and down, and the 3rd column oil cylinder and the 4th column oil cylinder vertically are installed between second head piece and second cross member;
Said transition crossbeam is flexible crossbeam.
The utility model is compared the beneficial effect that has with prior art: when coal-winning machine was worked, the column oil cylinder of the utility model all extended, and made the head piece of winning, transition crossbeam, second head piece withstand top board, carried out end support with gigantic mode.When need move forward along with propelling the utility model of coal-winning machine; The first column oil cylinder and second column oil cylinder retraction make the head piece of winning leave top board; First push cylinder, the elongation of second push cylinder promote first cross member and the reach of first head piece then; After reach is accomplished; The first column oil cylinder and the elongation of the second column oil cylinder make the head piece of winning withstand top board, and next the 3rd column oil cylinder and the 4th column oil cylinder retraction makes second head piece leave top board, and first push cylinder and the second push-and-pull oil bounce back simultaneously and spurs second head piece and the reach of second cross member then; After reach puts in place; The 3rd column oil cylinder and the elongation of the 4th column oil cylinder make second head piece withstand top board, and first head piece, transition crossbeam and second head piece all withstand top board at this moment, and the utility model continues to carry out end support with gigantic mode.Because the utility model is the walking of automatic moving type, and need not before a large amount of manually-operateds, improved operating efficiency, safety might as well.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure, 1 is the first column oil cylinder, and 2 is first head piece, and 3 is first connecting rod mechanism; 4 is the second column oil cylinder, and 5 are the transition crossbeam, and 6 is first push cylinder, and 7 is the 3rd column oil cylinder; 8 is second head piece, and 9 is second connecting rod mechanism, and 10 is the 4th column oil cylinder; 11 is second cross member, and 12 is second push cylinder, and 13 is first cross member.
The specific embodiment
Like Fig. 1, shown in Figure 2; A kind of automatic moving type follower ends head bracket; First head piece 2 and second head piece 8 connect together through transition crossbeam 5; Between first head piece 2 and second head piece 8, be connected with first push cylinder 6; Be connected through second push cylinder 12 with second cross member 11 at first cross member 13, first head piece 2 and first cross member 13 that connect through first connecting rod mechanism 3 are horizontally disposed with up and down, and the first column oil cylinder 1 and the second column oil cylinder 4 vertically are installed between first head piece 2 and first cross member 13; Second head piece 8 and second cross member 11 that connect through second connecting rod mechanism 9 are horizontally disposed with up and down, and the 3rd column oil cylinder 7 and the 4th column oil cylinder 10 vertically are installed between second head piece 8 and second cross member 11;
Said transition crossbeam 5 is flexible crossbeam.
The course of work of the utility model is: when coal-winning machine is worked; The first column oil cylinder 1, the second column oil cylinder 4, the 3rd column oil cylinder 7, the 4th column oil cylinder 10 all extend; Make the head piece 2 of winning, transition crossbeam 5, second head piece 8 withstand top board, carry out end support with gigantic mode.When need move forward along with propelling the utility model of coal-winning machine; The first column oil cylinder 1 and the second column oil cylinder, 4 retractions make the head piece 2 of winning leave top board; First push cylinder 6,12 elongations of second push cylinder promote first cross members 13 and 2 reaches of first head piece then; After reach is accomplished; The first column oil cylinder 1 and 4 elongations of the second column oil cylinder make the head piece 2 of winning withstand top board, and next the 3rd column oil cylinder 7 and the 4th column oil cylinder 10 retractions make second head piece 8 leave top board, first push cylinder 6 and second push-and-pull oil 12 retraction pulling second head piece 8 and 11 reaches of second cross member simultaneously then; After reach puts in place; The 3rd column oil cylinder 7 and the elongation of the 4th column oil cylinder 10 make second head piece 8 withstand top board, and this moment first, head piece 2, transition crossbeam 5 and second head piece 8 all withstood top board, and the utility model continues to carry out end support with gigantic mode.So circulation, along with coal-winning machine moves forward at work plane synchronously, the convenient and safe end support that carries out.
