Abstract
The utility model relates to a carriage of a bridge crane, which comprises a carriage frame, a hoisting mechanism and a carriage running mechanism. The utility model is characterized in that the carriage frame is composed of a pulley beam and vehicle wheel beams which are fixed on both ends of the pulley beam, a fixed pulley group is installed in the pulley beam, and a web plate is installed in the pulley beam. A reel group of the carriage is embedded between the two vehicle wheel beams, reel bearing seats are directly arranged on the vehicle wheel beams, and the height of the centre of the reel is reduced. Three fulcrum decelerators of the hoisting mechanism are hung outside the vehicle wheel beams; an electric motor and a disk brake are arranged on a flat base which is welded into a whole with the pulley beam for ensuring the running stability of a transmission mechanism. Simultaneously, a triad decelerator matched with the carriage running mechanism can change the traditional plane layout into solid layout. The space is sufficiently used, therefore, the utility model has the advantages of simple and compact structure and reduced shape size, limit and weight.
Description
[technical field] the utility model relates to a kind of OTC's trolley, belongs to the crane facility technical field.
[background technology] crane in bridge type is an indispensable important weight-lifting equipment in the material handling process, is widely used in places such as metallurgy, chemical industry, machinery, power station, and it mainly is made up of electric, dolly, cart, crane span structure (structure) four major parts.Dolly is the core of hoisting crane, is made up of trolley frame, lifting mechanism, wheeling mechanism.Vehicle structure and weight directly have influence on overall performance, oad and the weight of hoisting crane.The trolley frame such as the CN1066124C of conventional hoist disclosed " a kind of single crab of hoisting crane ", form planar structure by box beam with the top benchmark, with the plane is boundary, top is the mechanism driving part, the bottom is a hardware, the drive disk assembly of each mechanism as: electrical motor, drg, retarder, reel group, fixed pulley group etc. are all arranged with planar fashion.For avoiding the mutual interference between each parts, need to increase the trolley frame planar dimension, the weight that makes trolley frame is also along with increase.On the vertical direction, constitute the maximum height size of dolly with mechanism's the highest size of part parts and lower junction member minimum size sum, thereby cause the increase of dolly monnolithic case scantling of structure, Heavy Weight, it is in light weight little to hoisting crane to satisfy the user, the requirement that scope of work is big.
The problems referred to above that exist for the dolly that solves conventional hoist, CN2256417Y discloses a kind of " crane carriage of no vehicle frame speed governing ", its motor underframe is between retarder and tailstock, speed regulation device, main lifting motor, drg are on the motor underframe, the fixed pulley group is sleeved on the main hoisting drum, and the two ends of main hoisting drum are supported on respectively in retarder and the tailstock hole; The trolley travelling actuating device is installed on the casing of retarder, and the wheel that supports dolly is installed in respectively below retarder and the tailstock.Although said structure can reduce dolly weight and height, the overall construction intensity of dolly is very low, is not suitable for use in large lifting equipment.
[summary of the invention] the utility model has overcome the deficiency of above-mentioned prior art, and its purpose is to provide a kind of OTC's trolley.
The purpose of this utility model realizes by following technological means.
A kind of OTC's trolley comprises trolley frame, lifting mechanism, wheeling mechanism, it is characterized in that said trolley frame is made up of pulley beam and the wheel beam that is fixed on pulley beam two ends, and the fixed pulley group is arranged in the pulley beam.
This dolly places the fixed pulley group within the pulley beam, and within the pulley beam web is set, and not only makes the pulley beam have enough anti-twisting properties; Improve the stability of pulley beam pressure zone simultaneously, fully guaranteed the integrated carrying performance of trolley frame metal construction.
This dolly is embedded in the reel group between the two wheel beams, and the drum shaft bearing is directly installed on the wheel beam, has reduced the reel center height.Above-mentioned lifting mechanism three fulcrum retarders are suspended on the wheel beam outside; Electrical motor, plate disc brake are arranged on the platform that is welded as a whole with the pulley beam, have guaranteed these transmission device traveling comforts.Cooperate the three-in-one retarder of wheeling mechanism simultaneously, changed traditional floor plan and arranged for three-dimensional, made full use of the space, make the simpler compactness of dolly integral structure, overall dimensions, the limit and weight are minimized.Trolley frame pulley beam and wheel beam adopt T type structure fixedly to be assembled into one.Fixedly fit can adopt butt joint welding mode (referring to shown in Figure 1); Or employing overlap joint welding mode (as shown in Figure 4); Or employing bolted connection mode.
The utlity model has following advantage and effect:
One, the hoisting crane overall dimensions are little, compare with the hoisting crane of traditional design, dolly reduces height about 30%, the complete machine height reduces about 20%, the mouth of hook to dolly vertex size reduces about 30%, make the space minimum of hoisting crane demand, reduce track girder and factory building height, save the civil engineering cost.
Two, hoisting crane industry scope is big, and the hoisting crane of left and right end position of suspension hook and traditional design relatively reduces about 20%, satisfies user's requirement little to the limit; Gross horsepower reduces, and saves the energy.
Three, hoisting crane is in light weight, satisfies the requirement of user to the cart wheel load, reduces factory building track girder cost.
Four, compare with the hoisting crane of traditional design, the dolly expendable weight is about 30%, and the car load expendable weight is about 25%, reduces manufacturing cost.
Five, vehicle structure tube list compactness, in light weight, each beam stress is clearly reasonable, and fabrication properties is good.The brand-new layout of cooperate assembly pulley, suspension hook group, reel group, the retarder that hoists, moving three-in-one retarder, plate disc brake, electrical motor makes full use of the space, make the integral layout of dolly become more succinct, oad is littler, and makes, assembles simply, shortens the production cycle.Because the change of dolly, reduced the external load of girder, the cross section of girder is reduced, weight alleviates thereupon, has also reduced the load of traveling mechanism of the larger traveller simultaneously, has reduced wheel load, also makes the cart miniaturization that becomes, and has improved product market competitiveness.
