Abstract

The utility model discloses a belt conveyer vertical heavy bob tensioning device which comprises a tensioning roller [4], heavy bob boxes [3] and a sliding track guide post [1], and the sliding track guide post vertically guides the heavy bob boxes [3]. The belt conveyer vertical heavy bob tensioning device is characterized in that the number of the heavy bob boxes [3] is two, and the heavy bob boxes are symmetrically arranged on both sides of the tensioning roller [4] in the axial direction; and both ends of the heavy bob boxes [3] are fixed on a suspension beam [9], and are pressed on rotation shafts at both ends of the tensioning roller [4] through the suspension beam [9]. The utility model adopts two heavy bob boxes respectively arranged on both sides of the tensioning roller, shortens the height of the heavy bob boxes, and increases the tensioning stroke of a conveyer.

Description

Belt conveyer vertical heavy-hammer tension device

Technical field

The utility model relates to belt conveyer vertical heavy-hammer tension device.

Background technology

Belt conveyer is a kind of material transfer equipment commonly used, and its main composition comprises cylinder, carrying roller, actuating device, take-up device, support body and load-transfer device etc.The wherein main effect of take-up device: make load-transfer device have enough tension force, guarantee that the friction force that produces between load-transfer device and driving drum makes load-transfer device non-slip, and the sag of limit transport band between each carrying roller, conveyer is normally moved.

At present usually the vertical heavy-hammer tension device that adopts is mainly by tension drum, weight box, partly form the dragging track guide pillar of weight box vertically-guided etc., the tension drum of tension load-transfer device is positioned at weight box top, and weight box is along two upper and lower slips of dragging track guide pillar.This weight box occupation space is bigger, has shortened the tension travel of conveyer; Because weight box is along two upper and lower slips of guide pillar, guide pillar rigidity is often not enough, and weight box slides instability, influences conveyer and normally moves; Do not prevent the measure that weight box comes off owing to have, in case the load-transfer device fracture, weight box certainly will smash floor or ground, causes bigger safety misadventure.

Summary of the invention

The purpose of this utility model provides a kind of belt conveyer vertical heavy-hammer tension device that takes up room little, safe and reliable.

The utility model be achieved in that it comprise tension drum, weight box, to the dragging track guide pillar of weight box vertically-guided, described weight box is divided into two, be symmetricly set on the axial both sides of tension drum, two weight box two ends are fixed in the overarm, and are pressed in by overarm in the two ends rotating shaft of tension drum.Because weight box is arranged on the axial both sides of tension drum, shortened the height of weight box, increased the tension travel of conveyer.

The utility model is provided with two dragging track guide pillars in each weight box one side, i.e. every corresponding two guide pillars of overarm have increased the rigidity of dragging track guide pillar, and weight box slides more stable.

In order to improve safety, each weight box is provided with the fall arrest steel rope, and the lower end is fixed on the weight box, and the upper end is fixed on the conveyer girder steel.In case the load-transfer device fracture, owing to there is steel rope to haul, weight box can not pounded ground or floor, can be until the safety guard-safeguard effect.

A kind of priority scheme of the utility model is that recoil spring also is equipped with in the bottom of weight box.In case the load-transfer device fracture even weight box is run into ground or floor, owing in the weight box bottom recoil spring is housed, so also can alleviate its impulsive force to ground or floor greatly.

The utility model also is provided with guar plate on tension drum top, has prevented that effectively the material that falls on the conveyer from entering between tension drum and the adhesive tape, thereby damages adhesive tape.

The utility model adopts two weight boxs, and is divided into the tension drum both sides, has shortened the height of weight box, has increased the tension travel of conveyer.Increased the rigidity of dragging track guide pillar simultaneously, weight box slides more stable.By increasing anti-fall steel rope and recoil spring, safety performance improves greatly.
