Description
Technical field
The utility model relates to a kind of handling machinery, specifically a kind of electric single-beam trolley crane.
Background technology
The electric single-beam trolley crane is for general between factory metalworking workshop and loading-unloading vehicle and ground such as warehouse, be installed in the workshop above the green channel both sides on the roof truss beam, i-beam track is fixed on the roof truss beam, and trolley crane is suspended on the i-beam track by the both sides end carriage.This equipment can be installed concentratedly by more than enough cover trolley crane, adapts to many people and operates frequent use.There are several big shortcomings in the single-beam overhang crane of producing at present: the one, take material: this hoisting crane national standard 0.5T-5T, every equipment cart all has 16 of cast steel travelling wheels, (dolly employing steel-wire rope type electric block) is furnished with 8 of suspension plate, 12 of round steel bearing pins, the manufacturing process complexity, the steel waste is serious; The 2nd, unstable properties: 16 travelling wheels distribute and are installed on 8 suspension plate, and every link plate is fixed 2 travelling wheels, and suspension plate connects four round steel bearing pins of employing in end carriage and connects, and rocking property is bigger in the utilization and operation; End carriage also adopts bearing pin to connect in the girder connection, and rocking property is bigger in the utilization and operation; Noise is also very big simultaneously; Every end is established one group of cart and is driven the cart travelling wheel, is monolateral driving, gnaws rail easily; Safety device can't be set: in using operation as askewly draw, tiltedly hang and travelling wheel just occurs and overstep the limit, very dangerous.(referring to attached Fig. 1 and 2)
The utility model content
In order to address the above problem, the utility model provides a kind of operation not rock, and the electric single-beam trolley crane of saving in material.
The electric single-beam trolley crane, comprise girder, the girder two ends are connected and fixed with the end carriage of both sides respectively, described end carriage assembly adopts two channel-section steel dos-s to install side by side, the middle space of reserving frock both sides big wheel and orbital motion, gusset is strengthened in welding between two channel-section steel outside segmentations, and all weld with safety screen on channel-section steel two tops, makes two channel-section steels connect formation end carriage member in aggregates.
Described end carriage is provided with four big wheels, two near electrical motors be drive wheel, opposite side is two flower wheels, drive wheel and flower wheel wheel shaft pass the end carriage member and with its fixing weldering extremely, end carriage hangs on the i-beam track by drive wheel and flower wheel.
The wheel shaft of the cart travelling wheel of the utility model end carriage passes end carriage framing member and fixing locked, safe and reliable with it, and has cancelled original suspension plate and bearing pin, reduces and rocks noise; This end carriage only needs four cart travelling wheels, and every hoisting crane only needs eight travelling wheels altogether, reduces 50% than prior art, and connection suspension plate and round steel bearing pin need be installed, and has simplified manufacturing process, saves man-hour and steel.
Further improvement as such scheme, the drive wheel of described end carriage adopts the gap bridge transmission device to connect, this transmission device main body is a rotating shaft, rotating shaft two is located by bearing seat, coaxial in the rotating shaft two groups of transmission gears are housed, two groups of transmission gears mesh with two drive wheels respectively, by shaft drive mode transfer torque, two drive wheels are rotated synchronously.The advantage of this mechanism is a smooth running, is difficult for gnawing rail.
Another kind as such scheme improves, and bottom, described end carriage assembly stage casing is provided with the girder connecting panel, adopts locating dowel pin to captive joint with the screw one-time positioning with girder, cancels original bearing pin alive.In use not producing of the advantage of this structure rocked, noise is little.
The beneficial effects of the utility model are: simple in structure, save artificial and material, and also stable performance, noise is little, because falling proof device is housed, so safe and reliable, the user uses satisfied relieved.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is done step explanation:
