Chain elevator exempts to lubricate tail-pulley device.
The technical solution of the utility model is：
A kind of board chain hoisting machine exempts to lubricate tail-pulley device, including positioned at elevator the lowermost periproct housing, the periproct
The both sides of housing are respectively provided with a seal box, are equipped with lubricating arrangement in the seal box, it is characterised in that the lubricating arrangement bag
Include the guide rail being fixed on vertically by bolt in seal box, the guide rail be equipped with can in the sleeve block slided up and down along guide rail,
Wear-resisting overcoat is equipped with the sleeve block, the wear-resisting overcoat is fixed on inside sleeve block, is equipped with the wear-resisting overcoat wear-resisting
Inner sleeve, opposite between the wear-resisting overcoat and wear-resisting inner sleeve to slide, wear-resisting overcoat and wear-resisting inner sleeve are by Wear-resistant alloy steel material system
Into.
Further, lower leading screw is equipped with above the sleeve block, is provided with lower spring cup at the top of lower leading screw, lower spring cup leads to
Cross bolt to be connected with lower leading screw, the lower spring cup upper end is equipped with spring, and the spring upper end connects upper spring seat, the upper bullet
Upper leading screw is bolted in spring abutment, and sealing upper box part is equipped with the lead screw base passed through for upper leading screw.
Further, wear-resisting inner sleeve is internally provided with tailing axle, tailing axle and wear-resisting inner sleeve interference fit, weighting distribution wheel and lifting tail
Wheel is installed on tailing axle by keyway.
The beneficial effects of the utility model are：Parts wearability is good, working stability, service life length, and equipment is close
Envelope property is good, prevents flour dust overflow, substantially improves working environment, during the normal production run of elevator, passes through buffer spring, bearing block
Collision between briquetting, makes elevator operation more steady, easy to fluctuating for tail wheel.
Brief description of the drawings
The structure diagram of Fig. 1 the utility model.
In figure：Periproct housing 1, seal box 2, guide rail 3, sleeve block 4, wear-resisting overcoat 5, wear-resisting inner sleeve 6, lower leading screw 7, lower bullet
Spring abutment 8, spring 9, upper spring seat 10, upper leading screw 11, lead screw base 12, tailing axle 13, weighting distribution wheel 14, hoister rear wheel 15.
Embodiment
The present invention is further described in explanation and embodiment below in conjunction with the accompanying drawings.
A kind of board chain hoisting machine exempts to lubricate tail-pulley device, including positioned at elevator the lowermost periproct housing 1, the periproct
