Description
Technical Field
The invention relates to the technical field of mine equipment layout, in particular to a method for quickly adding a hydraulic support to a fully mechanized coal mining face and extending a conveyor tail.
Background
The fully mechanized mining face can extend or shorten along with mining. For the extension type, the original matched support of the working face and the conveyor equipment can not meet the normal production requirement, a hydraulic support is required to be added at an upper outlet, the tail of the conveyor is required to be extended so as to ensure that the equipment can cover the whole working face, and the manual construction amount is reduced.
Disclosure of Invention
The invention aims to solve the defects of time and labor consumption of a traditional method for adding a hydraulic support and extending a tail of a conveyor for an extension type of a fully mechanized mining face in the prior art, and provides a method for quickly adding a hydraulic support and extending a tail of a conveyor for the fully mechanized mining face to solve the problems.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a method for quickly adding a hydraulic support and extending the tail of a conveyor on a fully mechanized mining face comprises an air tunnel; the method comprises the following steps:
1) under the condition that the air way has no track and the section is small, a plurality of single pillars are arranged on the side of the old pond at the upper exit, and the hydraulic support is pulled to the designated position of the upper opening of the working face from inside to outside by utilizing the telescopic matching of the original support pushing oil cylinder and a conveyor chain;
2) then, the hydraulic support to be used is pressed to the working face downwards by the single prop, and the single prop is adjacent to the uppermost group of hydraulic pressure and is connected with a hydraulic pipeline;
3) when throw off the conveyer tail, use monomer pillar more than 2 to the head is connected ear, tooth root, dog, support base and is regarded as the rooting point to the lapse of chute, upwards to the mode of tail throw off sufficient clearance with tail and middle part chute, uses two monomer pillars directly to carry out remote confession liquid to the tail at the chute both ends that have backed off simultaneously again, makes the interval of tail and middle part groove be greater than the length of waiting to add the chute.
Preferably, in the step 1), 3-4 monomer pillars are erected on the side of the upper outlet old pond.
Preferably, in the step 3), two single supporting columns of the same type are directly abutted against the two ends of the abutted chute.
Compared with the prior art, the invention has the following beneficial effects:
the pushing oil cylinder is matched with the chain to pull the support, the single support props open the tail to replace a hoist to pull the tail open, so that the traditional plate trailer transportation is replaced, and the hoist is utilized to pull the tail open, so that a large amount of manpower and material resources are saved, the time is saved, and certain economic benefits are brought.
Detailed Description
In order to provide a further understanding and appreciation for the structural features and advantages achieved by the present invention, a detailed description of the preferred embodiments is provided below:
a method for quickly adding a hydraulic support to a fully mechanized coal mining face and extending a tail of a conveyor comprises the following steps:
step 1, under the condition that a wind tunnel has no track and a small section, 3-4 single pillars are erected on the side of an upper exit old pond, a hydraulic support to be installed is pulled to an upper opening designated position of a working face from outside to inside by utilizing a telescopic matching conveyor chain (phi 34 multiplied by 126) of an original support pushing oil cylinder, and the support is moved in a mode of transporting the support by using a flat car and hoisting by using a hoisting hoist.
Step 2, supporting the hydraulic support to be used to the working surface by the single prop downwards, and connecting the hydraulic support to the hydraulic pipeline adjacent to the uppermost group of hydraulic pressure;
and 3, when the tail of the conveyor is separated, more than 2 single support columns are used, the pushing head of the chute is connected with the lug part, the tooth root, the stop block and the bracket base to serve as rooting points, the tail and the middle chute are separated by enough clearance in an upward supporting mode, then two single support columns of the same type (1.6-4.5 m) are directly supported at two ends of the supported chute to carry out remote liquid supply to the tail, and the distance between the tail and the middle chute is larger than the length of the chute to be added.
The hydraulic support is added in advance, and the production time is not occupied. And pulling the standby support of the upper airway to the upper opening of the working surface by using the time of normal production shifts or work shifts, pushing the support to the working surface downwards by using the single support column by using the time of the work shifts, and connecting the hydraulic pipeline adjacent to the uppermost group of supports. The process does not affect normal production, a rooting column is arranged in front of the frame when the frame is moved, the pushing rod is connected to the rooting column through a chain, and the pushing oil cylinder is operated to move the frame.
The time delay conveyer tail of the duty-off is utilized, so that the influence on the production time is basically reduced and even eliminated.
The construction scheme is firstly an innovation on construction organization, the workload of 2 round shifts originally needed is implemented step by step, finally the construction is reduced to the construction by using the non-productive overhaul shift, and the influence on production construction is reduced to the minimum; secondly, the innovation on the construction process is that a pushing oil cylinder is matched with a chain to pull and move a support, and a single support props against the tail to open the tail instead of pulling the tail by a hoist; finally, the innovation on economic benefit is realized, the production team independently makes a scheme and constructs to save outsourcing cost, and a fund is saved for the mine.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
