Description
Technical field
The present invention relates to be used for the handling machinery industry, it is limited to be specially adapted to cart operation, can't satisfy suspension hook group end position, or the suspension hook group often needs the hoisting crane of fine motion operation.Belong to a kind of hoisting and conveying machinery and equipment.
Background technology
Traditional hoisting crane is realized that by traveling mechanism of the larger traveller vertical (along the cart track alignment) of suspension hook group moves, and by the side travel of wheeling mechanism realization suspension hook group, the suspension hook group does not all have relative motion with respect to dolly on vertical and horizontal.
In some special operation occasions, because of cart service direction and short transverse limited space, traveling mechanism of the larger traveller can't satisfy the working limit of suspension hook group, and traditional hoisting crane is restricted.
The present invention proposes a kind of low clearance double-layer trolley for crane,, under the state that traveling mechanism of the larger traveller stops, realizing vertically moving of suspension hook group by a cover transverse-moving mechanism and a double-layer trolley.
Hoisting crane primary and secondary dolly described in the patent CN200820220359.X has the following disadvantages:
1. sub-wheeling mechanism is similar with female wheeling mechanism, is made up of set of wheels, coupler, transmission shaft, retarder, electrical motor, drg, brake wheel etc., and the short transverse size is bigger;
2. the type of belt drive of sub-wheeling mechanism, weight is heavier, has increased the wheel load of sub-wheeling mechanism set of wheels.
With the shortcoming that the primary and secondary dolly exists, propose new scheme at existing hoisting crane, rearrange existing mechanism, adopt screw thread pair, revolute pair and moving sets etc., solved above deficiency.Satisfied hoisting crane under particular job environment to the requirement of work area, reduced energy consumption, strengthened the market competitiveness of group company's hoisting crane, estimate annual cost-saved 400,000 yuan.
Summary of the invention
Proposition of the present invention aims to provide an a kind of cover transverse-moving mechanism and double-layer trolley that pass through, and solves conventional hoist because of limited space, and traveling mechanism of the larger traveller can't satisfy the low clearance double-layer trolley for crane of the work requirements of suspension hook group end position.
Technical solution of the present invention is real like this:
A kind of low clearance double-layer trolley for crane, comprise wheeling mechanism, transverse-moving mechanism, lower floor's track, lifting mechanism, lower floor's trolley frame, upper strata track, upper trolley frame, the sliding roller assembling of load-carrying, it is characterized in that described upper strata track is layered on lower floor's trolley frame, the sliding roller of load-carrying is contained under the upper trolley frame and slides on the track of upper strata; Described lifting mechanism is fixed on the upper trolley frame; Described wheeling mechanism is installed on lower floor's trolley frame, drives double-layer trolley along lower floor's track side travel; Its feature is that also described transverse-moving mechanism is made up of coupler I, floating axle, coupler II, communtation deceleration device, screw rod, bearing, travelling nut, shifting axle, slide block, bolt, nut, packing ring, sliding guide groove, pressing plate, bolt II, the packing ring II of traversing motor, symmetric arrangement, traversing motor wherein drives floating axle by the coupler I, connect with the communtation deceleration device by the coupler II again, the drive screw rod rotates, and the other end of screw rod is supported in the bearing and forms revolute pair; Bearing, traversing electrical motor and communtation deceleration device all are fixed on lower floor's trolley frame; Form screw pair between travelling nut and the screw rod; Be fixed together by bolt, nuts and washers between travelling nut and the shifting axle, the two axial ends of shifting axle is formed revolute pair with two slide blocks respectively; Slide block and sliding guide groove are formed moving sets, and pressing plate is fixed on the sliding guide groove by bolt II and packing ring II; Sliding guide groove is fixed on the upper trolley frame, drives the upper trolley frame and moves at cart track alignment trace along the upper strata track.
Revolute pair between described shifting axle and the slide block, the moving sets between slide block and the sliding guide groove can compensate in the upper trolley frame moving process vibration on short transverse and displacement.
Between described upper trolley frame and the upper strata track, the sliding roller assembling of load-carrying is installed, has reduced the running resistance of upper trolley frame, compressed the size of whole double-layer trolley in short transverse.
Compared with prior art, advantage of the present invention is conspicuous, mainly shows:
1, increase the work area of suspension hook group:
2, compact conformation, overall dimension is less;
3, whole dolly weight is lighter, saves cost;
4, this equipment satisfied hoisting crane under particular job environment to the requirement of work area, reduced energy consumption.
