Description

Buffer stop

Technical field

The utility model relates to a kind of buffer stop, especially relates to a kind of overhead manned equipment tunnel or narrow, short employed buffer stop.

Background technology

Known, in the colliery inclined shaft was produced, mine car was main transportation means.Because the inclined shaft gradient is about positive and negative 35 degree, the mine car kinetic energy that goes is very big, is prone to cause unhooks, haulage cable to break off and the generation derailing accident; Simultaneously, winch breakdown also is the key factor that derailing accident takes place, and this brings great potential safety hazard with regard to the safety in production of giving the colliery, because of personal casualty and financial resources, material resources that derailing accident causes are lost all very big.Wherein existing country has for this reason issued rules such as a series of safety regulations in coal mine and some regulations; " safety regulations in coal mine " (2012) regulation inclined gallery planted agent installs the derail avoidance facility; Wherein the grade change point place, pittop of inclined gallery should install stop device; The inclined gallery planted agent installs " normally closed " buffer stop, but the said equipment actv. is avoided the generation of all kinds of sliding train in inclined lane accidents, has guaranteed the inclined gallery transportation safety.

Mostly general buffer stop backstop is steel rope netting formula or rigidity planer type structure; Like Chinese CN201042959Y, its manner of execution be generally driver train (motor reducer or cylinder) through about the pair of traction steel rope of configuration drive backstop and rise or fall, when mine car passes through; Backstop is opened; Mine car passes through, and falls through back stop again, backstop is fallen be in " normally closed " state of keeping off a car.

Also have a kind of buffer stop to drive the part track outward and rise or fall,, make the backstop 6 of buffer stop be in the clearance or the state of keeping off a car like Chinese CN101289091A through steel rope (having steel pipe to support).When keeping off a car state, steel rope drives the part track and rises, and is in the state of keeping off a car; During the mine car operation, steel rope drives the part track and falls, and track is overlapped, and this moment, the backstop steel rope was positioned at below the track, and mine car passes through.

Wherein, For the former; In the tunnel that is provided with overhead manned equipment (or narrow, stoop way), though guaranteed the inclined gallery transportation safety, the haulage cable that lifts backstop can be positioned at the position of the operation of overhead manned equipment just; Hinder the normal operation of overhead manned equipment, produce to the colliery and bring inconvenience.

For the latter; Track rise just or the backstop structure that falls though can be installed in being provided with the tunnel of overhead manned equipment, have solved the problem to the overhead manned equipment restriction; But owing to after cutting next section on the track of former laying that will be in the tunnel when installing, this structure backstop is installed again.This structure one is that work capacity is big, is because former track is easy to generate uneven or uneven problem with the track that overlapped again, and during the mine car operation during this position, the as easy as rolling off a log derailment occurring that occurs has increased the potential safety hazard of mine car operation greatly.Especially this structure does not meet the relevant regulations of " safety regulations in coal mine ", does not have promotional value.

Summary of the invention

Therefore, the purpose of the utility model is to provide a kind of and can plays protective action and can be applicable to the overhead manned equipment tunnel or buffer stop narrow, stoop way.

The technical scheme that the utility model adopts is:

The specific embodiment

With reference to explanation accompanying drawing 3, in the tunnel, be furnished with the monkey car, known; The formal full name of monkey car is the mine cableway, is commonly called as built on stilts pedestrian's device, is mainly used in personnel's transportation in tunnel; Obviously, when being provided with the monkey car, existing buffer stop can influence the normal operation of monkey car mostly.

Based on the utility model; Referring to Figure of description 1-3; Adopted such technical scheme, a kind of buffer stop comprises backstop 6, from one group of energy absorber 4 of the double-end steel rope 5 of backstop and the every end steel rope corresponding bonded assembly of institute; And be arranged on the steering structure of backstop 6 tops and the distributor 3 that is connected said backstop 6 via this steering structure through hauling rope 2; These structures have kept the general structure of current similar buffer stop basically, and for fear of keeping in check with the monkey car, said hauling rope 2 is connected in the middle of the said backstop top.In structure shown in Figure 3, can more clearly express, among Fig. 3, the layout monkey car on the both sides, tunnel, hauling rope 2 are transferred from the middle and are drawn backstop 6 up-downs.As previously mentioned, this structure can not influence the up-down of backstop, but this structure can be avoided the influence to the monkey car effectively, guarantees the normal operation of monkey car, and in structure shown in Figure 3, backstop is transferred on the guide rail or is lower than the bottom of waiting and just can meet the demands.

Hauling rope 2 preferably adopts steel rope, adopts common winch to get final product about said distributor 3, can also adopt other to have the equipment that winch, cylinder etc. can the folding and unfolding steel ropes.

In such application, known, generally adopt automatically controlled; Usually buffer stop also all dispose the electric cabinet that is used to collect control, generally adopts electrically operatedly like winch, controls so that collect; Certainly be in requirement of explosion also have adopt pneumatic/hydraulically operated, simultaneously, the coupling backstop goes up and down; Generally also be provided with parts such as position transduser and status alert device, but this paper relates generally to the improvement of physical construction, and automatically controlled part is repeated no more.

About said steering structure, be mainly used in drawing of hauling rope 2, can adopt structures such as hole, bearing pin, preferable selection then is for being arranged on the fixed pulley 1 directly over the said backstop, like accompanying drawing 1 or 2, fixed pulley is fixed on the top, tunnel.

Also expressed the two states of backstop among Fig. 1, a kind of is the state that is positioned at the bottom, and the state of promptly keeping off a car is needed normally off.The state on top then is current state.In this programme, also having the third state, is exactly the state shown in the accompanying drawing 3, and backstop is further transferred, and is beneficial to the monkey car and passes through.

Comprise vertically suitable 3 ~ 5 horizontally disposed pillars that connect about said backstop, said steel rope passes pillar correspondingly and is connected with the said energy absorber 4 of side.Need to prove, because the traction of steel rope 5 may not be in vertical state under the backstop running condition, but be a kind of numeric state when dangling naturally, also connects through steel rope 8 between common pillar.General steel rope 5 has three just can meet the demands, and therefore many three is good, but can not be more than 5, the more complicated otherwise the system that can make becomes.

According to " safety of coal mines operating instruction " principle that not pedestrian, pedestrian do not drive a vehicle of driving a vehicle, a kind of application according to a kind of buffer stop of the utility model is described.

When mine car moves, wait and 9 can not move.The clearance state of backstop 6 and the normally closed state of keeping off a car; With reference to Fig. 1, shown in Figure 2: when mine car comes downwards to the desired location that backstop 6 rises; Main Control Tank is through logic analysis, and concurrent load instruction passes to the aux. controls case, after the aux. controls case is received signal; The control releasing winch rises backstop 6, and winch stops action after position sensing detects backstop 6 to arrive assigned address.

When mine car goes upward to the desired location of backstop 6 rises; Main Control Tank is through logic analysis, and concurrent load instruction passes to the aux. controls case, after the aux. controls case is received signal; The control releasing winch is transferred backstop 6, and winch stops action after position sensing detects backstop 6 to arrive assigned address.

When 8 operations of monkey car, when mine car does not move, show with reference to Fig. 1, Fig. 3.

When 8 operations of monkey car; Main Control Tank is through logic analysis, and concurrent load instruction passes to the aux. controls case, after the aux. controls case is received signal; The control releasing winch all falls to raceway surface with backstop 6, and winch stops action after position sensing detects backstop 6 to arrive assigned address.At this moment, when the monkey car moves, the interference with general buffer stop can not occur and move the time for the monkey car.

When the monkey car was out of service, releasing winch was mentioned backstop 6, and backstop 6 returns to normally off.

In backstop 6 rise processes, the flicker of backstop 6 clearance lamps, back clearance lamp Chang Liang puts in place.Fall in the process at backstop 6, backstop 6 stops the lamp flicker, stops lamp Chang Liang after putting in place.

The clearance of backstop 6 when backstop 6 moves at mine car, normally closed pushing-off the wagons state and the control that backstop 6 is let pass, normally closed pushing-off the wagons state receives electric cabinet when the monkey car moves.The state that backstop 6 is done action by above-mentioned requirements begins respectively to stop; The position transduser (sensor) that receives to install on the actuating unit sends instruction; And then to electric cabinet feedback electric signal; Output instruction signal is further sent in logic analysis through electric cabinet PLC program again, the operation of control actuating unit, thereby control backstop 6 residing mode of operations.

The mercury switch 10 of threading off is fixed on the centre place of arrester top; Be connected with the nylon rod at first pipe place of protecting tube with inhaling rope device 11; When the generation sport car hits net; Mercury in the mercury dropout switch 10 flows backwards and sends signal to Main Control Tank, and this moment, backstop 6 was in normally off, and the alarm display cabinet sends alerting signal.

Inhale rope device principle of work: utilize the energy storage principle of volute spiral spring, the volute spiral spring outer end is fixed on the spring box inwall, and the inner is fixed on the mandrel, and when backstop 6 fell, steel rope 8 drove rope sheave and on mandrel, applies torque, and volute spiral spring is by rolling-in and stored energy; Steel rope 8 is no longer stressed when backstop 6 is mentioned, and the volute spiral spring loose winding discharges deformation energy and output services moment, steel rope 8 by rolling-in on rope sheave.
