Abstract
The utility model discloses a full-mechanized mining working face ended support, which aims to resolve the problem that an existing ended support cannot push a machine head component safely and quickly and cannot move in place. The full-mechanized mining working face ended support comprises a support, a support top beam, a pushing jack, a machine head component and a rest jack, the top of the support is connected with the support top beam, the front end of the bottom of the support is connected with the machine head component via the pushing jack, and the lower side of the support top beam is in hanging connection with the rest jack. The full-mechanized mining working face ended support is simple in structure, can greatly increase work efficiency, meets requirements of fast pushing a machine head and realizing forward movement of the support, and guarantees safe and fast advancing of a working face.
Description
Technical field
The utility model relates to the fully-mechanized mining working faces end head support.
Background technology
Along with the continuous development of combining the technology of adopting, the fully-mechanized mining working faces end head support has been widely applied to the big-and-middle-sized fully-mechanized mining mine in various places.In the working face extraction process, according to the working surface production operation, work plane adopts the cut sth. askew mode of feed of termination, whenever cuts a circulation, draws and moves face end support and move head one time by face end support.In this process, face end support can't be passed equipment such as drag conveyor head and elevating conveyor safely, fast in the process of the top head of being everlasting, and pushes up motionless when serious fully; Support the time also appears in support reach itself to be drawn and moves motionless situation, or it is not in place to move frame, needs repeatedly debugging; Move and also often run into the phenomenon that frame was fought, stung to support in the frame process, or support draw move on to topple over behind the position, crooked, and support is unable to lift problems such as the head float coal is many.
At the problem that occurred in the use, conclusion sums up, the reason that these a series of problems take place mainly is because these triangle zone special circumstances of the most difficult maintenance of face end, it is softer to add the upper plate lithology, rigidity is little, head ponding is many, base plate further is softened after meeting water, the support body of support own is big, base plate after argillization is planted up and down, takes place to fall into end phenomenon, thereby causes drag conveyor head passing seat and face end support to pass very heavy not on same level, difficulty when causing the top head, or support reach time bracket base itself to fall into the end too big, add the reason that the head float coal is more, cause the difficulty of trying to stop people from fighting each other, or try to stop people from fighting each other and put the after-poppet base in place owing to do not entail much effort, make support take place crookedly to topple over.
How to guarantee stope safety, advance fast, become the important research direction of present industry.
Summary of the invention
The purpose of this utility model provides a kind of fully-mechanized mining working faces end head support, with the purpose that reaches stope safety, advances fast.
The utility model is achieved through the following technical solutions:
The fully-mechanized mining working faces end head support comprises that support, set cap, passing are very heavy, nose assembly, steady be very heavy, and a top of the trellis connects set cap, and bottom front is by passing very heavy connection nose assembly, and the set cap below hangs that to be connected with steady very heavy.The steady that hangs below set cap is very heavy, to propping up the end steady effect of lifting of erecting.The top head the time handle it support lifted the end, guarantee to pass very heavy and head is passed seat on same level, thereby pass head smoothly; Try to stop people from fighting each other the time, use it that support is lifted the end and play the steady effect, support is entailed much effort, the increase support draws the stability when moving, draw motionlessly thereby break away from face end support, drawing fights when moving stings the frame situation, and draws the problems such as after-poppet is crookedly toppled over, float coal is many of moving.
Described steady is very heavy to be that the hydraulic pressure steady is very heavy.
The utility model mechanism is simple, can improve the operating efficiency of face end support greatly, has reached the requirement of quick passing head and support itself reach, has guaranteed work plane safety, has advanced fast.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-support, 2-set cap, 3-are passed very heavy, 4-nose assembly, the 5-steady is very heavy.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the fully-mechanized mining working faces end head support comprises support 1, set cap 2, passes very heavy 3, nose assembly 4, steady is very heavy 5 that support 1 top connects set cap 2, bottom front connects nose assembly 4 by passing very heavy 3, and set cap 2 belows hang and are connected with steady very heavy 5.
Steady very heavy 5 is that the hydraulic pressure steady is very heavy.
Claims (2)
1. fully-mechanized mining working faces end head support, comprise that support (1), set cap (2), passing very heavy (3), nose assembly (4), support (1) top connect set cap (2), bottom front connects nose assembly (4) by passing very heavy (3), it is characterized in that the suspension of described set cap (2) below is connected with steady very heavy (5).
2. fully-mechanized mining working faces end head support according to claim 1 is characterized in that described steady very heavy (5) is very heavy for the hydraulic pressure steady.
