Abstract
The utility model belongs to the mine spacing protection field of driving a vehicle specifically is a conveyer walking spacing protection device, has solved the problem among the background art, protection device includes travel switch and baffle, and travel switch sets up on conveyer walking wheel lateral wall, and travel switch includes the cantilever contact, and the baffle setting is in the guide rail side at travel switch place, and the conveyer keeps off with the baffle when advancing to baffle department and connects the cooperation, and travel switch is connected with one of them a set of emergency stop protection contact of entry driving machine electric control box. The installation limiting protection device can not influence the walking of the transshipment wheel, can not cause the rollover of the conveyor, and can lead the unit to be powered off and stop running through the emergency stop of the unit of the development machine, thereby leading the conveyor to stop running, being very safe in operation and sensitive in reaction, not needing the field attendance of workers, saving labor force, playing a protection role on development equipment, being convenient in operation, lower in cost and good in limiting protection effect.
Description
Technical Field
The utility model belongs to the spacing protection field of mine driving specifically is a conveyer walking spacing protection device.
Background
In a coal mine, the coal outlet flow of the development machine is as follows: first conveyor → second conveyor → tape conveyor. The second conveyor of the existing development machine is a transfer device which is used by matching the development machine with a rubber belt conveyor and is convenient for coal discharging, one end of the second conveyor is fixed at the tail part of the development machine, the bottom of the other end of the second conveyor is provided with a traveling wheel, and the second conveyor walks along with the development machine on a runway butted with the belt tail in a driven manner. Because of no protection facilities, a nursing transfer worker must be specially dispatched, but because the running distance from the head to the tail of the second conveyor is long, and the visibility of a roadway is low when the heading machine cuts rocks, the following problems often occur in the walking process: (1) the heading machine excessively walks in the advancing process, and the steel wire rope of the towing cable is broken or the towing cable device is damaged; (2) the development machine is transferred away from the runway in the advancing process so as to fall off the runway; (3) the tunneling machine is excessive in walking in the backward moving process, and the transshipment tail pressing or the transshipment head is pushed to the cable basket to cause equipment damage and other problems.
Disclosure of Invention
An object of the utility model is to solve in the background art the problem provides a spacing protection device of cargo airplane walking.
The technical proposal of the utility model for solving the technical problem is that: the utility model provides a conveyer walking limit protection device, includes travel switch and baffle, travel switch sets up on conveyer walking wheel lateral wall, travel switch includes the cantilever contact, the baffle sets up in the guide rail side at travel switch place, and the conveyer is advanced when locating to the baffle cantilever contact and baffle fender and is connect the cooperation, travel switch is connected with one of them a set of scram protection contact of entry driving machine electric cabinet. Conveyer walking limit protection device's theory of operation: when the conveyor runs to the limit position of the baffle, the cantilever contact can be blocked by the baffle fixed on the side wall of the track, the travel switch is triggered at the moment, a feedback signal of the travel switch is fed back to the electric control box of the heading machine, the emergency stop protection contact is disconnected, the main pipe enables the heading machine to be in emergency stop and power off, and therefore the conveyor also stops running.
The utility model has the advantages that: the problem in the background art is solved, the walking of reprinting wheel neither can be influenced to the spacing protection device of installation, also can not cause turning on one's side of cargo airplane, and make the unit outage bring to rest through entry driving machine unit scram moreover to make cargo airplane bring to rest, the operation is very safe, and the reaction is sensitive, does not need staff on the spot to watch moreover, saves the labour, has played the guard action to heading equipment, and convenient operation, the cost is lower, and spacing protection is respond well.

Detailed Description
In order to illustrate the embodiments of the present invention or the technical solutions in the prior art more clearly, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 and fig. 2, the walking limit protection device of the conveyor according to the present invention will now be described.
The utility model provides a conveyer walking limit protection device, as shown in figure 1, includes travel switch 1 and baffle 2, travel switch 1 sets up on the conveyer walking wheel lateral wall, travel switch 1 includes cantilever contact 3, baffle 2 sets up in travel switch 1 place guide rail side, as shown in figure 2, and when the conveyer marchd 2 departments to baffle 2, cantilever contact 3 kept off with the baffle 2 and connect the cooperation, travel switch 1 is connected with one of them a set of scram protection contact of entry driving machine electric cabinet. Conveyer walking limit protection device's theory of operation: when the conveyor runs to the limit position of the baffle 2, the cantilever contact 3 can be blocked by the baffle 2 fixed on the side wall of the track, the travel switch 1 is triggered at the moment, a feedback signal of the travel switch 1 is fed back to the electric control box of the heading machine, the emergency stop protection contact is disconnected, the main pipe enables the heading machine to be in emergency stop and power off, and the conveyor also stops running.
Further, as a conveyer walking limit protection device's embodiment, baffle 2 sets up on the guide rail through mount 4, mount 4 is connected with the guide rail lateral wall through the bolt and nut subassembly, baffle 2 is L shape bent plate, baffle 2 is connected with mount 4 through the bolt and nut subassembly. The fixing frame 4 and the baffle 2 are convenient to obtain, the cost is lower, no special structural structure needs to be designed, and the manufacturing and the assembling are convenient.
Further, as a conveyer walking limit protection device's embodiment, be provided with the bolt through-hole 5 that the several is used for 2 positions of adjusting the baffle on mount 4. The position of the baffle 2 can be flexibly adjusted through different bolt through holes 5, so that different vehicle stopping requirements are met.
Further, as a conveyor walking limit protection device's embodiment, mount 4 is made by the angle steel. Convenient material taking and low cost.
