Abstract
The invention relates to a gap bridge device, in particular to a push-and-pull folding gap bridge at a fully-mechanized coal mining emergency exit for pedestrians, and solves the problem of frequent start and stop of a front conveyor due to the reason that underground staff go to and fro between a fully mechanized coal mining face and an intake entry reversed loader. The push-and-pull folding gap bridge comprises a horizontal baseplate, a horizontal push-and-pull sliding plate, a folding stair and folding handrails, wherein an L-shaped inner edgefold is arranged at each of the left edge and the right edge of the upper surface of the horizontal baseplate; the two L-shaped inner edgefolds and the horizontal baseplate are encircled to form two horizontal chutes; a horizontal steel tube is fixed to each of the left edge and the right edge of the lower surface of the horizontal push-and-pull sliding plate; the horizontal push-and-pull sliding plate are supported on the upper surface of the horizontal baseplate in a sliding manner by the two horizontal steel tubes; the left edge and the right edge of the horizontal push-and-pull sliding plate are respectively embedded into the two horizontal chutes in a sliding manner. The gap bridge device is suitable for underground production.
Description
Technical field
The present invention relates to Overbridge device, specifically a kind of combining adopted extra exit pedestrian's push-pull folding gap bridge.
Background technology
In downhole production process, staff need to frequently travel to and fro between between fully-mechanized mining working and air intake lane elevating conveyor. At present, staff comes and goes this section of place at every turn, all needs directly to cross over the head location of the anterior transporter that is arranged on fully-mechanized mining working. And in order to ensure that staff crosses over the head location of anterior transporter (preventing that staff from surprisingly falling into the anterior transporter moving and causing casualty accident) safely, need first anterior transporter to be closed down, after having crossed over, more anterior transporter is started, cause thus anterior transporter frequent start-stop, thereby delay the normal production time on the one hand, cause on the other hand the operating current of anterior transporter frequently to increase, and then affect the safe operation of anterior transporter. Based on this, be necessary to invent a kind of brand-new device, travel to and fro between to solve underground work personnel the problem that causes anterior transporter frequent start-stop between fully-mechanized mining working and air intake lane elevating conveyor.
Summary of the invention
The present invention travels to and fro between in order to solve underground work personnel the problem that causes anterior transporter frequent start-stop between fully-mechanized mining working and air intake lane elevating conveyor, provides a kind of combining to adopt extra exit pedestrian's push-pull folding gap bridge.
The present invention adopts following technical scheme to realize: combine and adopt extra exit pedestrian's push-pull folding gap bridge, comprise horizonal base plate, horizontal push-and-pull slide plate, folding step, stow-away arm rest hurdle;
Wherein, the upper surface left margin of horizonal base plate and upper surface the right is along L shaped interior flanging together with being respectively provided with; The L shaped interior flanging of twice and horizonal base plate surround twice horizontal concrete chute jointly;
The lower surface left margin of horizontal push-and-pull slide plate and lower surface the right are along being respectively fixed with a horizontal steel tube; Horizontal push-and-pull slide plate is by two horizontal steel tube sliding supports in the upper surface of horizonal base plate, and the left margin of horizontal push-and-pull slide plate and the right are along sliding and be flush-mounted in twice horizontal concrete chute respectively;
Two longeron rear ends of folding step are hinged with upper surface left-front corner and the right front angle of upper surface of horizontal push-and-pull slide plate respectively;
The number on stow-away arm rest hurdle is two; The lower edge on two stow-away arm rest hurdles is hinged with the upper outer surface of the L shaped interior flanging of twice respectively.
When use, the motor shroud at the lower surface of horizonal base plate and fully-mechanized mining working place is fixed. Concrete use procedure is as follows: in the time that staff need to travel to and fro between between fully-mechanized mining working and air intake lane elevating conveyor, first two stow-away arm rest hurdles are upwards turned down, and are kept upright in two stow-away arm rest hurdles, the pull-out forward in the twice horizontal concrete chute from horizonal base plate by horizontal push-and-pull slide plate again, then folding step is turned down downwards, and make two longeron front ends of folding step be overlapped on elevating conveyor place, air intake lane, thus the comprehensive extra exit pedestrian's push-pull folding gap bridge of adopting of the present invention is launched. Now, horizonal base plate, horizontal push-and-pull slide plate, folding step form the bridge that a head upper from anterior transporter is crossed over jointly, staff can come and go between fully-mechanized mining working and air intake lane elevating conveyor by this bridge that (staff pass by successively horizonal base plate, horizontal push-and-pull slide plate, folding step, can arrive air intake lane elevating conveyor from fully-mechanized mining working. Otherwise staff pass by successively folding step, horizontal push-and-pull slide plate, horizonal base plate, can arrive fully-mechanized mining working from air intake lane elevating conveyor). In said process, if run into, anterior transporter is overhauled, first folding step is upwards turned down, and folding step and horizontal push-and-pull slide plate are stacked, again horizontal push-and-pull slide plate is pushed in the twice horizontal concrete chute on horizonal base plate backward, then two stow-away arm rest hurdles are turned down downwards, and two stow-away arm rest hurdles and horizontal push-and-pull slide plate are stacked, thus the comprehensive extra exit pedestrian's push-pull folding gap bridge of adopting of the present invention is folded up, after Awaiting Overhaul, again launched to use.
Based on said process, of the present invention combining adopted extra exit pedestrian's push-pull folding gap bridge by adopting brand new, form a bridge that the head upper from anterior transporter is crossed over, make staff in the time travelling to and fro between between fully-mechanized mining working and air intake lane elevating conveyor, without the head location of directly crossing over anterior transporter, and only need can come and go by this bridge, make thus anterior transporter without carrying out frequent start-stop, thereby effectively avoid the normal production time to be delayed on the one hand, effectively avoid on the other hand the operating current of anterior transporter frequently to increase, and then effectively ensure the safe operation of anterior transporter.
The present invention is rational in infrastructure, it is ingenious to design, and efficiently solves underground work personnel and travels to and fro between the problem that causes anterior transporter frequent start-stop between fully-mechanized mining working and air intake lane elevating conveyor, is applicable to downhole production.
