Abstract
The utility model discloses a top protecting device and an end support of a movable inversion-proof rack, which comprise a top protecting plate, wherein the rear end of the top protecting plate is hinged on one side of the top beam or the shield beam of a hydraulic support, and the front end of the top protecting plate is hinged on a supporting plate; a jack is connected between the top protecting plate and the top beam or the shield beam, and a supporting rod is connected between the top protecting plate and the supporting plate; and the top protecting plate, the supporting plate and the supporting rod form a triangular structure. The top protecting device and the end support can vertically move in a working state, and the support can integrally hung down when going down into a well so as to facilitate the parallelism of a left rack and a right rack which integrally go down into the well; and the utility model has the advantages of simple structure, convenience in use and high work efficiency.
Description
Technical field
The utility model relates to a kind of colliery fully-mechanized mining hydraulic support, relates in particular to a kind of movable anti-fall calliper and protects ejection device and face end support.
Background technology
In coal mining equipment, about two one group of formula end hydraulic supports are face end supports of using always.
There is anti-down casing the general inboard of face end support of the prior art, by protect top board and back timber stretch out casing realize respectively protecting the top and the anti-fall calliper function.
There is following shortcoming at least in above-mentioned prior art:
The face end support integral body width of going into the well is excessive, and what adopt usually is the mode of disintegrating greatly so face end support is gone into the well, and the down-hole needs support is reinstalled, and complex structure, uses inconvenient, inefficiency.
The utility model content
The purpose of this utility model provides a kind of movable anti-fall calliper simple in structure, easy to use, high efficiency and protects ejection device and face end support.
The purpose of this utility model is achieved through the following technical solutions:
Movable anti-fall calliper of the present utility model protects ejection device, comprise and protect top board, the back timber of the described rear end of protecting top board and hydraulic support or a side of caving shield are hinged, described front end and gripper shoe of protecting top board is hinged, described protecting between top board and described back timber or the caving shield is connected with jack, described protecting between top board and the gripper shoe is connected with support bar, and described top board, gripper shoe and the support bar of protecting forms triangular structure.
Face end support of the present utility model, a side of the back timber of this face end support or caving shield is provided with above-mentioned movable anti-fall calliper and protects ejection device.
The technical scheme that is provided by above-mentioned the utility model as can be seen, the movable anti-fall calliper that the utility model provides protects ejection device and face end support, because it is hinged to protect a side of the back timber of the rear end of top board and hydraulic support or caving shield, the front end and the gripper shoe of protecting top board are hinged, protect between top board and back timber or the caving shield and be connected with jack, protect between top board and the gripper shoe and be connected with support bar, protect top board, gripper shoe and support bar and form triangular structure.Duty can be up and down, can integral body when support is gone into the well hang down be convenient to about frame and frame integral body go into the well simple in structure, easy to use, high efficiency.
Description of drawings
Fig. 1 protects the structural representation of ejection device and face end support duty for the movable anti-fall calliper that the utility model embodiment provides;
The movable anti-fall calliper that Fig. 2 provides for the utility model embodiment protects the elevational schematic view that ejection device and face end support move the frame state;
The movable anti-fall calliper that Fig. 3 provides for the utility model embodiment protects the floor map that ejection device and face end support move the frame state;
The movable anti-fall calliper that Fig. 4 provides for the utility model embodiment protects the whole and frame of ejection device and the face end support view of going into the well.
Among the figure: 1, back timber or caving shield, 2, jack, 3, protect top board, 4, support bar, 5, gripper shoe.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
Movable anti-fall calliper of the present utility model protects ejection device and face end support, its preferable specific embodiment as shown in Figure 1:
Comprise and protect top board, the back timber of the described rear end of protecting top board and hydraulic support or a side of caving shield are hinged, described front end and gripper shoe of protecting top board is hinged, described protecting between top board and described back timber or the caving shield is connected with jack, described protecting between top board and the gripper shoe is connected with support bar, and described top board, gripper shoe and the support bar of protecting forms triangular structure.
The tie point at described support bar two ends has at least one to be to connect by the pin that is removably connected.
The pin joint at described jack two ends has at least one to be hinged by dismountable bearing pin.
One side of the back timber of face end support or caving shield is provided with above-mentioned movable anti-fall calliper and protects ejection device.
For two one group of formula face end supports, comprise left socle and right support, the side that described left socle is relative with right support is respectively equipped with described movable anti-fall calliper and protects ejection device.
The utility model can be applicable in the coal mining equipment about on two one group of formula end hydraulic supports, be hinged on back timber and caving shield inboard, the exposed top board space that is used for forming between the frame about supporting, stop dropping of roof cracking rock, avoid spoil to enter internal stent, cause to operating personnel's injury and to relevant device and destroy, and in moving the frame process, play a kind of safety device of anti-fall calliper function; The utility model is connected with back timber with jack, and duty can be up and down, can integral body when support is gone into the well hang down be convenient to about frame and frame integral body go into the well.
As Fig. 2, shown in Figure 3, the step pitch of walking need be fallen frame and in face end support single frame in moving the frame process, fall after the frame walking about protect and still remain with enough amounts of lap between top board, and the anti-fall calliper function between the frame about transferring frame jack common guarantee in moving the frame process.
As shown in Figure 4, when face end support is gone into the well, protect each structural member of top board and jack and can be in relaxation state, fall in the support inboard, width reached the requirement minimum range when assurance support and frame were gone into the well.
The utility model is simple and reasonable, can realize protecting top and anti-fall calliper function simultaneously, and in light weight, thereby solved existing end hydraulic support and protected top and tilting prevention device cost height, baroque problem for enterprise provides cost savings, also provides condition for downhole safety; When face end support is gone into the well, protect each structural member of top board and jack and can be in relaxation state, fall in the support inboard, three sections disintegration before, during and after only need are incited somebody to action so face end support is gone into the well, about frame adopt and the frame integral body form of going into the well gets final product, go into the well dismounting time in the process thereby saved support, improved production efficiency.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
