Description

The slat conveyer machine for zipper

Technical field

The utility model relates to a kind of slat conveyer machine for zipper, and it belongs to the machine for zipper that a kind of mining large-scale slat conveyer uses.

Background technology

The slat conveyer of colliery use now often causes conveyor chain fracture and chain fatigue to prolong in long production process, for the assurance slat conveyer normally uses, need carry out tight chain to slat conveyer.The defeated chain tensioner sheet that at present tight chain uses, a kind of is CN2806389Y disclosed " scraping transporter chain tensioner sheet ", this chain tensioner sheet mainly adopts connecting rod and drag hook structure, lifting by screw mandrel drives the flexible of drag hook, thereby reaches the purpose of degree of tightness chain, and this chain tensioner sheet need could be realized the purpose of flexible drag hook by transmission repeatedly, efficient is lower, because force application mechanism adopts the structure of connecting rod, and its intensity is less, it is limited to bear load-carrying capacity simultaneously.Another kind of " chain tensioner sheet " that discloses for CN101108478A, this chain tensioner sheet adopts hand crank driven gear to rotate, and then spurs chain link and move, and has improved work efficiency, has strengthened simultaneously and has born load-carrying capacity.But this chain tensioner sheet is the special tool of small-sized slat conveyer configuration, and pulling force is little, and stroke is short, and phenomenons such as run, drip, leak easily take place the oil lubricating that smear on its surface, and machine oil resistance is big after a little while, influence pulling force; And this chain tensioner sheet employing hand crank driven gear rotation, both taken manpower, efficient is also low.

Summary of the invention

The purpose of this utility model is that shaking manually of solving that existing chain tensioner sheet exists not only required great effort but also ineffective technical barrier, provides that a kind of power is big, efficient is high and can show the slat conveyer machine for zipper of pulling force size.

The utility model for the technical scheme that solves above-mentioned technical barrier and take is: the slat conveyer machine for zipper, comprise machine for zipper agent set and device for measuring force, wherein: described machine for zipper agent set is by casing, a pair of gear, a pair of gear wheel shaft, tooth bar, the tooth bar sheath, a pair of drag hook and motor are formed, a pair of gear is arranged on a pair of gear wheel shaft, the bolster of a pair of gear and a pair of gear wheel shaft is arranged in the casing, the bolster of gear wheel shaft is contained on the casing by bearing, the lateral surface of casing is provided with case lid, motor be located on the case lid and with casing in gear mesh, the tooth bar sheath is located at the opposite side of casing, tooth bar is contained in the tooth bar sheath and with the gear teeth of a pair of gear wheel shaft and is meshed, first drag hook is located at an end of tooth bar, and second drag hook is located at an end of tooth bar sheath bottom surface and corresponding with first drag hook; Described device for measuring force is made up of sensor and pulling force telltale, and sensor is arranged on second drag hook, and the signal end of sensor is connected with the input end of pulling force telltale.

One side of described tank floor is provided with supporting leg.

Described motor adopts HM Hydraulic Motor.

Described tooth bar sheath and casing are fixed as an integral body.

Because the utility model has adopted technique scheme, replace the hand crank driven gear to rotate with motor, thereby drive tooth bar and make the drag hook work of stretching, reach the purpose of degree of tightness conveyor chain, not only saved manpower, improved work efficiency, and tooth bar sheath and casing be fixed as one, strengthened the rigidity of casing, shortened the jib-length of gear wheel shaft, greatly improved material bending resistance deformation strength, reduced the deflection between the parts, simultaneously the lubricated employing Nonlubricated bearing between gear and the gear wheel shaft, both saved machine oil, avoid oil leakage phenomenon, also made more compact structure reasonable, reduced friction to greatest extent; The utility model has increased device for measuring force, and sensor is directly arranged on the drag hook, directly shows the variation of pulling force by telltale, has strengthened the stability and the safety of persons of its equipment.Therefore, compare, the utlity model has and effectively to avoid conveyor chain easy fracture, fatiguability to prolong cutter chain and power is big, efficient is high, can show advantage such as pulling force size with background technology.
