Abstract
The utility model relates to a parallel guide tensioning device of bucket elevator and is characterized in that the device adopts a roller type counterweight body, the counterweight body is supported on a bucket elevating driven wheel bearing seat which can slide in a vertical guide rail via two supporting rods which are installed symmetrically; a parallel guide mechanism is installed, a rotary sleeve is sleeved on the outside of the counterweight body, two ends of the sleeve are installed with two sets of rack-and-gear meshing mechanisms symmetrically, the gear is fixed at both sides of the sleeve, the rack is fixed on the inner wall of the same side frame. The utility model is especially designed for the elevator with ultra-height and large transport capacity, the traction part can be tensioned automatically, and the useful effect is that the parallel guiding can be realized during the tensioning process, and the parallel state can be locked, thereby guaranteeing stable operation of elevator.
Description
Technical field:
The utility model relates to bucket elevator.More specifically say so and be applied in tightening device in the bucket elevator.
Bucket elevator is widely used in the vertical transport of industry powder and granule shape materials such as cement, metallurgy, chemical industry, grain.The hair style gig adopts adhesive tape or chain as traction piece usually, the tightening device of adhesive tape or chain is the requisite component part of bucket elevator, the effect of tightening device is the gig traction piece to be in operation be in rational tensioning state all the time, to guarantee the gig smooth operation.Simultaneously, for make traction piece can be stressed evenly, do not swing, do not take place sideslip, also must possess the function of " parallel tensioning ".But the tightening device that uses mostly is weight hammer type or lever at present, and the problem that exists in concrete the use is that not only tension effects is poor, is difficult to satisfy the requirement of hypervelocity, big operational throughput bucket elevator.More distinct issues are to guarantee parallel tensioning.
Summary of the invention
Technical problem to be solved in the utility model is to avoid above-mentioned existing in prior technology weak point, provides a kind of bucket elevator parallel conductive to tightening device, to guarantee the smooth operation of hypervelocity, big operational throughput bucket elevator.
The technical scheme that the utility model technical solution problem is adopted is:
Constructional feature of the present utility model is to adopt the roll-type balance weight body, and described balance weight body is bearing on the bucket elevator follower shaft bearing that can slide in longitudinal rail by the symmetrically arranged cramp bar in the left and right sides; Parallel-guiding is set, described parallel-guiding is to be with rotating sleeve in the outside of balance weight body, the two ends of sleeve are symmetrical arranged two groups of rack-and-gear engaging mechanisms, and described gear connects firmly at the sleeve two ends, and described tooth bar is fixedly installed on the framework madial wall of the same side.
Compared with the prior art, the utility model is not only realized at random from tensioning by balance weight body, its beneficial effect more is embodied in the utility model by being symmetrical arranged two groups of rack-and-gear engaging mechanisms, make the two ends of sleeve realize rotating synchronously, and drive roll-type balance weight body parallel longitudinal moves, thereby effectively to the tensioning process of traction piece implement parallel conductive to, and can keep this parastate effectively and lock.Greatly improved the smoothness of operation of hypervelocity, big operational throughput gig.

Fig. 2 is the utility model structure weight scheme drawing.
Fig. 3 is the utility model tube-in-tube structure scheme drawing.
Fig. 4 is the utility model balance weight body and sleeve mounting structure scheme drawing.
Fig. 5 is the utility model parallel-guiding plan structure scheme drawing.
The specific embodiment:
Referring to accompanying drawing, present embodiment adopts roll-type balance weight body 1 (shown in Figure 2), and balance weight body 1 is bearing in by the symmetrically arranged cramp bar 2 in the left and right sides on the bearing seat 4 of bucket elevator flower wheel 3 (Fig. 1, shown in Figure 4).In concrete the enforcement, according to the version of routine, on the frame of relevant position, longitudinal rail is set, bearing seat 4 is embedded therein, and can move up and down therein.Cramp bar 2 is a screw rod.
Shown in the figure, parallel-guiding (Fig. 1, shown in Figure 5) is set in the present embodiment, parallel-guiding is to be with rotating jacket casing 5 (shown in Figure 3) in the outside of balance weight body 1.The two ends of sleeve 5 are symmetrical arranged two groups of rack-and-gear engaging mechanisms.Wherein, gear 6 connects firmly at the two ends of sleeve 5, and tooth bar 7 is fixedly installed on the madial wall of the same side framework 8.For fear of the axial motion of sleeve 5, quill shaft is set to position-limited trough 9, position-limited trough 9 is positioned on the madial wall of framework 10 of tooth bar 6 relative sides, and the edge of the gear 6 on the correspondence position is limited in wherein.
In concrete the enforcement, for the safety action alerting ability, gear 6 is the gear teeth at the position that it is meshed with tooth bar 7, and is smooth arc at its position that is positioned at position-limited trough 9.
In the working process, parallel conductive is to provide the tensioning dynamics by balance weight body and gig flower wheel to the realization of tensioning function, and traction piece is remained on the suitable degree of tension.Because being symmetrical arranged of two groups of pinion and racks, the synchronous shift of balance weight body and flower wheel depends on the displacement of sleeve, and sleeve can only be by its two ends the synchronous rolling of gear on tooth bar parallel to bottom offset, also be that sleeve axis can only be done parallel longitudinal and moves.Thereby the flower wheel of the balance weight body that is positioned at it and bottom is implemented the parallel longitudinal guiding by sleeve.And this parastate is same because being symmetrical arranged of two ends rack-and-gear engaging mechanism obtains locking.
