Abstract
The utility model relates to a coal mining machine, in particular to an integrated fully mechanized top-coal caving face end support frame, which solves the problems of low support and protective efficiency, poor effect and the like in the existing fully mechanized top-coal caving face end support and protective technology. The end support frame comprises two parallel single-row support frames, any one single-row support frame comprises a base, four hydraulic struts are arranged on the base, the upper end of the four hydraulic struts is provided with top beams, the base and the tail ends of the top beams are connected through a four-connecting-rod mechanism, a transverse pulling jack is connected between the parallel and adjacent top beams, and a side pushing jack is also arranged on the base. The type of the frame is the combined type, the integral performance is good, the whole body after the combination has great work resistance, and the support and protective capability is stronger than that of a single-body post.
Description
Technical field
The utility model relates to a kind of coal-cutting machinery, is specially a kind of comprehensive extracting and caving face face end support.
Background technology
In recent years, the Coal Mining Equipment Complement technology has obtained very fast development, and sublevel caving hydrau lic support has also obtained ripe development in each ore deposit.But aspect the top-coal caving face end support, also there is the problem of some restriction safety in production, needs to improve perfect.The back supporting that the top-coal caving face end support is meant work plane elevating conveyor and front and back, the head upper top board that slips promptly transports lane and work plane infall.At present, the domestic top-coal caving face end support monomer column support patterns that adopt also have the support pattern that adopts face end support more.But all there is following problem respectively in these two kinds of support patterns:
The support pattern of 1 monomer column: 1) labor strength is big, and the user of service is many; 2) supporting control top board ability, support cost height, part material can not be realized recycling; 3) prop drawing difficulty, potential safety hazard is big, and especially the prop drawing of goaf and first file leader's frame tail boom trigonum causes very big threat to workman's life security; 4) supporting efficient is low; 5) coal-winning machine need be shut down when tip position approximately and be carried out supporting half an hour, causes equipment operation rate low, influences the further raising of per unit area yield.
Mainly there is following problem in the support pattern of 2 former face end supports: 1) because the supporting scope is big, support Design is long, overweight, when running into special roof and floor situation, occurs killing frame easily, draws motionless situation; 2) very flexible moves difficulty, the recovery of can not disintegrating when running into mal-condition, and support cost is higher relatively; 3) take transportation lane sectional space, influence the pedestrian space, increase flowing resistance.
Summary of the invention
Problems such as the utility model is low in order to solve the supporting efficient that exists in the existing top-coal caving face end support technology, weak effect and a kind of comprehensive extracting and caving face face end support is provided.
The utility model is realized by following technical scheme, a kind of comprehensive extracting and caving face face end support, comprise two single-row supports arranged side by side, any single-row support comprises base, base is provided with four hydraulic props, and four hydraulic prop upper ends are provided with back timber, and the end of base and back timber is connected by quadric chain, be connected with between the side by side adjacent back timber and horizontally draw very heavyly, it is very heavy also to be provided with thruster on the base.
Adopt monomer supporting and the end support mode that light-duty face end support supporting combines, design novel light combined face end support, its characteristics are as follows:
1 this type is two one group, single frame adopts single-row four pylon types, back timber and base adopt plate shape case structure, the support afterbody adopts positive four-bar linkage structure, single frame width only 600mm wide about, long-pending little with the top board direct contact surface, be subjected to top board extruding degree low, facts have proved, can adapt to abominable roof and floor condition admirably;
2 these types are the mid-combined type (two group) that lands of elevating conveyor, and one group has 8 root posts, and two are horizontally drawn very heavy connection by 4, draw to move with elevating conveyor to be connected, and base is provided with jack can adjust direction at the elevating conveyor ledge, and moving is step type,
3 these types are combined type, good integrity, and the whole working resistance in combination back is big, and support capacity is than strong many of monomer column;
Behind the 4 use side head brackets, by pass oil cylinder with elevating conveyor and face end support each other fulcrum move forward fast, when unit cut the head position, obviously shortened downtime, improved supporting efficient;
5 labor strength obviously reduce, and safety factor has obtained improving greatly.
6 run into abominable especially top board condition, and this support can split the back and replace with monomer column, split the back maximum weight less than 2.5 tons, and size is also little, can install easily and reclaim.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the lateral view of Fig. 1
Among the figure: slip before the single-row support of 1-, 2-elevating conveyor, 3-, slip behind the 4-, 5-horizontally draws that very heavy, 6-hydraulic prop, 7-base, 8-thruster are very heavy, 9-draws and moves very heavy, 10-quadric chain, the single-row support of 11-
The specific embodiment
As shown in Figure 1, 2, a kind of comprehensive extracting and caving face face end support, comprise two single-row supports arranged side by side 1,11, any single-row support 1 comprises base 7, base 7 is provided with 6, four hydraulic prop 6 upper ends of four hydraulic props and is provided with hinged back timber 12,13, and the end of base 7 and back timber 13 is connected by quadric chain 10, be connected with between the side by side adjacent back timber and horizontally draw very heavyly 5, also be provided with thruster very heavy 8 on the base 7.
Two single-row supports of this face end support are arranged symmetrically in elevating conveyor 2 both sides, and move very heavy 9 and be connected on the ledge Connection Block of elevating conveyor 2 both sides by drawing, the preceding head that slips is overlapped on the base 7 of face end support 1 with back slide head, single frame width only 600mm wide about, single frame adopts row 4 posts, two one group totally eight bracket upright post 6 can reach bigger working resistance.13 meters of stent length, top horizontally draws very heavy 5 to connect by 4 between two, and single frame base 7 is provided with 4 thrusters very heavy 8 and acts on the enterprising line position adjustment of elevating conveyor 2 ledges.
