Abstract
A self locking type derailleur for a scraper conveyor and a transfer conveyor is characterized in that a stopper is clamped between the derailleur and a rear upright plate of a transverse beam of a headstock, lateral portions of a fixed plate of the derailleur are provided with wedge-shaped surfaces, the wedge-shaped surfaces are engaged with wedge surfaces of the stopper which are arranged correspondingly, a large end of the stopper is arranged facing towards one side of a middle plate of a headstock of a conveyor, a screw hole is arranged on the end surface of the large end of the stopper, a bolt with adjustable length and a fastening nut are assembled inside the screw hole, and the top surface of the bolt clings to the bottom surface of a tongue board. The self locking type derailleur is simple in structure and obvious in effect, can effectively prevent vibrating, avoids damaging connection portions of the derailleur due to vibration of the derailleur, eliminates noise generated by vibration of the derailleur, prolongs service life thereof, and reduces integral maintenance, thereby increasing production efficiency of coal mines.
Description
Technical field
The utility model relates to colliery transportation system middle scraper machine, elevating conveyor with dialling the chain device.
Background technology
The scraper plate machine, claim drag conveyor again, it is the unique haulage device of present longwell formula coal-face, elevating conveyor, claim bridge conveyor again, be installed in the coal-face lower gangway, its effect is that the coal that work plane scraper plate machine transports is transported on the extensible belt conveyor, reduces adhesive tape dismounting number of times when conveyor is flexible.
Scraper plate machine, elevating conveyor operating principle: as haulage gear, realize the transportation of coal as load carrier with chute by the electrodeless circulation scraper chain of walking around head sprocket wheel and tail wheel.
When conveyer moves, can mesh smoothly and separate for making the scraper plate chain and sprocket, avoid chain jamming, pile chain, accident such as cause that chain rupture or sprocket wheel are cracked a joke, on the chain-drive section headstock, be equipped with and dial the chain device.Its effect is: when the round-link chain of chain wheel assembly and engagement is thrown off, prevent that chain link is stuck in the sprocket wheel groove and can not throws off at normal separation point.Dialling the chain device is welding structural element.Install when dialling the chain device, shift fork inserts in the groove of sprocket, dials the chain device and utilizes hyoplastron or bearing pin to be fixed on the headstock.The chain device of dialling that uses does not at present possess auto-lock function, and unbalance stress when dialling the work of chain device is difficult to avoid scraper chain to be given and dials the vibration that the chain device brings, and dials chain device point of attachment because the damage that vibration brings and produce noise owing to dial the vibration of chain device thereby cause.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of simple and feasible scraper plate machine, elevating conveyor to dial the chain device with self-locking, prevent to dial the chain device and vibrate to dialling the damage that chain device point of attachment brings, reduce and safeguard, increasing work efficiency.
The utility model technical solution problem adopts following technical scheme:
The design feature that the utility model scraper plate machine, elevating conveyor are dialled the chain device with self-locking is to dial clamping block between chain device and the headstock crossbeam back vertical plate; The fixed head sidepiece of described group of chain device is set to lozenges, match with the wedge surface of described lozenges with the block of corresponding setting, the big end of described block plate one side in the conveyer headstock is installed, on the big end end face of described block, be provided with screw, being furnished with length-adjustable bolt and clamp nut in the described screw, fits in the end face of described bolt and the bottom surface of hyoplastron.
The utility model can reach the self-locking purpose by mechanism's angle of friction that the angle that wedge surface is set is less than or equal to twice.Compared with the prior art, the utility model is simple in structure, effect is remarkable, can effectively prevent to dial the vibration of chain device, avoid dialling the chain device and vibrate, eliminated because of dialling the noise that the vibration of chain device produces, the application life of having improved group chain device to dialling the damage that chain device point of attachment brings, reduce the maintenance of complete machine, thereby improved the Coal Production benefit.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model force analysis.
Below by the specific embodiment, the utility model is described in further detail in conjunction with the accompanying drawings
The specific embodiment
Referring to Fig. 1, in the present embodiment, dialling clamping block 2 between chain device 1 and the headstock crossbeam back vertical plate 3; The fixed head sidepiece of dialling chain device 1 is set to lozenges, match with the wedge surface of this lozenges with the block 2 of corresponding setting, the big end of block 2 plate 6 one sides in the conveyer headstock are installed, on the big end end face of block 2, be provided with screw, being furnished with length-adjustable bolt 4 and clamp nut 5 in the screw, fits in the bottom surface of the end face of bolt 4 and hyoplastron 7.
As shown in Figure 1, in concrete the enforcement, with the box-shaped beam of headstock crossbeam front vertical plate 9, headstock crossbeam base plate 8 and headstock crossbeam back vertical plate 3 compositions one upper opening, will dial chain device 1 and be enclosed in the box-shaped beam, block 2 clampings are being dialled between chain device 1 and the headstock crossbeam back vertical plate 3.Adjust the height of bolt 4, fitted in its bottom surface with hyoplastron 7, and bolt 4 is locked with clamp nut 5.When conveyer is worked, scraper chain and sprocket wheel have the driving force of dialling chain device 1 makes group chain device 1 to block 2 places one side mobile trend be arranged, group chain device 1 is set cooperates the wedge surface angle of wedge less than mechanism's angle of friction, then dial chain device 1 and can't be moved, realize self-locking by wedging with block 2.
For this mechanism, in order to determine its condition of self-locking, the condition that can directly act in the angle of friction according to driving force solves.As shown in Figure 2, establishing and dialling the wedge surface angle that chain device 1 cooperates with block 2 is α, and mechanism's angle of friction is ψ.Because making the upwards loose driving force of moving back of block 2 is R
12So, if R
12Position and normal institute angle (α-ψ) is in total reaction R
32In the folded angle of friction ψ of normal scope, then mechanism will self-locking.The condition of self-locking that can try to achieve this mechanism thus is:
α-ψ≤ψ, that is α≤2 ψ.
