Description

A kind of bucket elevator double leval jib automatic takeup

Technical field

The utility model relates to bucket elevators, more particularly to a kind of bucket elevator automatic takeup.

Background technique

Bucket elevator is widely used in the conveying of granular material in the industrial process such as chemical industry, metallurgy, building materials.Its conveying side Formula is divided into chain conveyer and V belt translation, and corresponding traction piece is mainly chain or wire belt, and in the composition of equipment, two kinds defeated Send mode necessary mating corresponding tensioning apparatus, so that traction piece keeps certain tensioning shape during equipment is run State reduces traction piece to the service efficiency of the abrasion of wheel body and raising equipment.Existing bucket elevator tensioning apparatus is mostly Fixed tensioning and rack-and-pinion tensioning.Fixed tension type is by increasing weight body in side, using lever principle, by weight body Weight acts on hoister rear wheel.Rack-and-pinion tension weight body guarantees weight body effect by the vertical engagement of rack-and-pinion On hoister rear wheel.But existing tensioning mode cannot be guaranteed that tail wheel both ends synchronize free tensioning, affect great wheel and tail The depth of parallelism of wheel, easy Caton in operation, limits the promotion of production efficiency.

Summary of the invention

The utility model is to provide a kind of company of bucket elevator four to avoid above-mentioned existing deficiencies in the technology Bar automatic takeup makes tail wheel both ends obtain synchronously control, guarantees the depth of parallelism of great wheel and tail wheel, to guarantee to run suitable Freely, production efficiency is improved.

The utility model adopts the following technical scheme that in order to solve the technical problem

The utility model bucket elevator double leval jib automatic takeup is structurally characterized in that: it is same vertical to be in tail wheel Be arranged in parallel weight body in plane, and a pair of of vertical link positioned at the two sides of weight body symmetrically connects at the both ends of weight body and tail wheel It connects, constitutes the vertical four-bar mechanism in perpendicular；The up and down motion of tail wheel makes the vertical four-bar mechanism synchronizing moving； Being in parallel arrangement in same level with the weight body has rocker arm shaft, and a pair of of rocker arm positioned at the two sides of rocker arm shaft is in rocker arm The both ends of axis and weight body symmetrically connect, and constitute the horizontal four-bar mechanism in horizontal plane；The rocker arm shaft is supported on tail, And can be rotated, it is fixedly connected between the rocker arm and rocker arm shaft, the shaft end of the weight body is supported on rocker arm in the form of sliding block On sliding slot in, and can move and rotate in the sliding slot, the sliding slot is arranged along the length direction of rocker arm.

The design feature of the utility model bucket elevator double leval jib automatic takeup is lain also in: the sliding slot is arranged Length limits the up and down motion distance of the tail wheel in the sliding slot.

The design feature of the utility model bucket elevator double leval jib automatic takeup is lain also in: the weight body is column Shape body, both ends are set as fixing axle, and radial through-hole is arranged in the fixing axle, and the top of the connecting rod is set using bolt fixation It sets in the radial through-hole, the fixation position between connecting rod and weight body is adjustable by bolt, the wheel of connecting rod and tail wheel It is attached between axis using bearing block.

Compared with the prior art, the utility model has the beneficial effect that:

1, the utility model is balance automatic stretching structure, forces tail wheel both ends are synchronous to rise using parallel four-bar linkage Drop, ensure that the depth of parallelism of great wheel and tail wheel, and then tail wheel is made to be close to the free parallel sliding of adhesive tape always, realize auto-tensioning While, it can be effectively controlled rubber belt from deviating, operation is smooth, substantially increases production efficiency.

2, the utility model limits the stroke that moves up and down of tail wheel using the sliding slot in rocker arm, improves equipment fortune Capable safety.

Specific embodiment

The structure type of bucket elevator double leval jib automatic takeup is in the present embodiment:

As depicted in figs. 1 and 2, parallel arrangement weight body 4 in same perpendicular is in the tail wheel of bucket elevator 6, A pair of of vertical link 5 positioned at the two sides of weight body 4 symmetrically connects at the both ends of weight body 4 and tail wheel 6, constitutes in perpendicular Vertical four-bar mechanism, as elevator traction piece is with the up and down motion of tail wheel 6, including weight body 4 vertical four Link mechanism and 6 synchronizing moving of tail wheel.

As shown in Figure 1, Figure 2 and Figure 3, parallel arrangement is in same level with weight body 4 rocker arm shaft 2, positioned at shaking A pair of of rocker arm 3 of the two sides of arm axle 2 is symmetrically connect in rocker arm shaft 2 with the both ends of weight body 4, and the level four constituted in horizontal plane connects Linkage；Rocker arm shaft 2 is supported on the tail 1 of bucket elevator, and can be rotated, and is fixedly connected between rocker arm 3 and rocker arm shaft 2, Whole rigid structural is formed, the shaft end of weight body 4 is supported in the sliding slot 3b on rocker arm 3 in the form of sliding block, makes weight body 4 Shaft end can 3b be mobile along the chute and rotation, sliding slot 3b are arranged along the length direction of rocker arm 3.

In specific implementation, corresponding structure setting also includes:

As shown in figure 4, one end is provided in round through-hole 3a on rocker arm 3, the other end is set as sliding slot 3b；Utilize circle Rocker arm 3 is fixed at the both ends of rocker arm shaft 2 by through-hole 3a, according to the length for requiring setting sliding slot 3b, makes the fortune up and down of tail wheel 6 Dynamic distance is limited in sliding slot 3b, and sliding slot 3b is straight trough, and the both ends of straight trough are arc-shaped.

As shown in figure 5, weight body 4 is column, both ends are set as fixing axle 4b, and fixing axle 4b is embedded in the form of sliding block In the sliding slot 3b on rocker arm 3, fixing axle 4b can be slided and be rotated in sliding slot 3b, be provided with radial through-hole on fixing axle 4b 4a sets the bigger Step Shaft of outer diameter, the top of connecting rod 5 for the fixing axle of the position radial through-hole 4a to increase intensity End is fixed in radial through-hole 4a using bolt, and the fixation position between connecting rod 5 and weight body 4 can be carried out by bolt Adjustment, is attached between connecting rod 5 and the wheel shaft of tail wheel 6 using bearing block 6a.

When 6 stress of tail wheel moves up and down, weight body 4 moves up and down therewith, and rocker arm 3 is made to generate swing, and fixing axle 4b exists It slides and rotates in sliding slot 3b, since a pair of of rocker arm 3 is to be fixedly connected with rocker arm shaft 2, form rigidity entirety, therefore, benefit Forced synchronism is implemented at both ends to weight body 4 with a pair of of rocker arm 3, forces tail wheel 6 in both ends synchronization lifting with this, realizes automatic The synchronization lifting of tensioning and tail wheel both ends keeps elevator operation smooth, effectively improves to guarantee the depth of parallelism of great wheel and tail wheel Production efficiency.
