Abstract
The utility model relates to a double-conveyer roof caving suspension support frame, comprising a main frame 1 and a sub frame 2 between which a sliding mechanism 3 is arranged for interconnection. A top beam 4 is lengthened, 6-8 upright posts are arranged under the top beam, and the upright post 6 in the back row is a supporting post. A tail beam 7 is installed at the back part of the main frame, an interlock anti-falling mechanism is arranged between the frames, and the operating mechanism of a cantilever is a four-connecting rod turnover mechanism. The utility model is especially suitable for mechanized roof caving coal mining faces in middle and small coal mines and can also be used on other working faces. The utility model has the advantages of high efficiency, high recovery rate, good stability, and favorable top plate management.
Description
The utility model is an a kind of pair of transport plane caving coal cantilever support.Be specially adapted to the middle and small scale coal mine machine and adopt top-coal caving face.It comprises body frame and subframe, between body frame and the subframe slipping mechanism is arranged.
Therefore because that cantilever support has is simple in structure, cost is low, relatively is applicable to middle and small scale coal mine.Cantilever support also is being applied to top coal caving at present.Every of existing cantilever support is made up of a body frame and a subframe, has slipping mechanism to be connected between body frame and the subframe.Body frame and subframe are made up of back timber and pillar.The cantilever support that is used for top coal caving is four-column type (major and minor each two column).Single chute is placed in the middle of two row's columns, with manually with coal shovel in chute, its weak point is that production efficiency is low owing to be subjected to structural limitations can only be used for big gun to adopt, the percent recovery is low, can't adopt two transport plane caving coal technology by the realization machine.Support stability is poor in addition, and supporting intensity is not enough.Be prone to away oblique phenomenon when moving frame, can not realize the even control top board that carries.The forestope of body frame back timber is a telescopic structure, is passive protecting, in time top, controlling machine road coal.
The purpose of this utility model is to overcome the weak point of above-mentioned prior art, provide a kind of can realization machine adopt two transport plane caving coal technology, production efficiency height, two transport plane caving coal cantilever supports that the percent recovery is high.
The purpose of this utility model also is further to improve the stability and the roof control effect of support.
Can reaching of the purpose of this utility model by following measure:
1. the back timber length that adds long stent.
2. column quantity is increased to 6～8 every.
3. last row's column adopts the anti-post that tilts to support.
4. set up tail boom at the back timber end.
The increase of set cap lengthening and pillar not only improved support supporting intensity, strengthened the stability of support, and make support that the space of laying forward and backward transport plane be arranged.Back row's column changes the stability that increased support behind the anti-post and the balance ability from old man's horizontal thrust into.Formed " eight " font district between anti-simultaneously post and the tail boom, not only be convenient to the laying of back transport plane, and increased and put the coal space, drawing effectiveness is good.Significantly reduce bottom plate triangular coal amount, improved top-coal recovery rate.
The purpose of this utility model can also reach by following measure:
Set up the anti-down mechanism of interlocking between frame and frame, this mechanism can solve away oblique problem in moving the frame process, keep certain frame spacing, and each frame is connected as a single entity, and has strengthened the support resistance to overturning, realizes the even control top of carrying.
By the original telescopic convertible mechanism of four connecting rods that changes into, it is very good to connect, and helps the maintenance of top, machine road coal with the forestope of body frame back timber.
The utility model has been compared following advantage with existing cantilever support in sum:
1. can adopt two transport plane top coal cavings by the realization machine, the production efficiency height, and improved the percent recovery greatly.
2. support stability is good.
3. can manage top board effectively.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the front view of an embodiment of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the partial enlarged drawing of Fig. 2.
The utility model is described in further detail below in conjunction with accompanying drawing:
See Fig. 1 and Fig. 2.1 is body frame, the 2nd among the figure, and subframe has slipping mechanism 3 to be connected to each other between body frame and the subframe.Major and minor back timber 4 adds and grows to 2830mm, and its arranged beneath has 8 root posts, and wherein the column 5 of vertical support is totally 6, and last row's column is two anti-posts 6 that are in tilted layout.At the rear portion of body frame 1 tail boom 7 is installed, it and anti-post 6 form splayed and put the coal space.Transport plane after its arranged beneath.Preceding transport plane is arranged in first row's column front.
See Fig. 2 and Fig. 3.Chain tilting prevention device between support and the support has axle sleeve 10, guide rod 8 and slide block 9.Axle sleeve 10 is arranged the back timber outside that is installed in body frame 1 with the back timber parallel longitudinal.Be installed in the subframe back timber outside with the guide rod 8 of back timber parallel longitudinal, slide block 9 is arranged on it.There is slide bar 11 to be installed in the axle sleeve endoporus on the slide block 9, can slides at certain-length upper edge endoporus.Spacing by block 15 and spring wire 14.When moving frame, axle sleeve drives slide block and slides on guide rod.The sliding distance of block 15 and spring wire 14 restriction slide bars 11 makes the certain frame spacing of maintenance between the support.
12 is forestopes of body frame back timber among Fig. 1.Handle its support machine road top seam or top board by four connecting rod switching mechanisms 13.
