Abstract
The utility model discloses a steel coil transport trolley, which belongs to the technical field of cold rolling equipment and is used for solving the problem that while running under a heavy load, the trolley cannot complete the coiling task alone. The utility model adopts a technical scheme that the transmission mechanism of the steel coil transport trolley consists of a small transmission shaft and a gearbox, wherein the gearbox is connected with a vehicle body; a gear wheel and a pinion, which are meshed together, are arranged in the gearbox; a hydraulic motor shaft is connected with the pinion by a small transmission shaft; and the gear wheel is connected with a driving shaft. In the utility model, due to the replacement of chain wheel transmission by the gear transmission, under a condition of meeting functional requirements, the motor can be used under a condition of a high output rotating speed, the operation efficiency of the motor is improved and the phenomenon that the output power of a low-speed large-torque hydraulic motor running at a low speed is greatly reduced is avoided, so the problem that the heavily loaded trolley running at a low speed operates unsteadily is solved. The steel coil transport trolley has the characteristics of small volume, light weight, simple control equipment and reliable operation and is suitable to be promoted and used as complete equipment of a cold rolling mill.
Description
Technical field
The utility model relates to the dolly that a kind of cold rolling unit transports coil of strip, belongs to the cold-rolling equipment technical field.
Background technology
At cold rolling unit entrance, coil of strip dolly commonly used will be delivered on the uncoiler apart from 4～5 meters outer coil of strips of unit, so that unit is handled being rolled into the nearly two meters belt steel surface of external diameter.The coil of strip dolly that uses is made of bracket, lifting car body, walking mechanism three parts at present.Coil of strip is positioned over the bracket top.Walking function by dolly is realized coil of strip is delivered to the other end (uncoiler mandrel place) from the end (saddle) of track, will expect on the volume to mandrel with combining of dolly elevating function then.Bright spot of the present utility model is the improvement of walking mechanism.So introduce drives structure.Its drive principle of this car is, revolution drives the sprocket wheel rotation that is installed in its axle head, pass motion to sprocket wheel on the driving shaft by roller chain, the rotation of drive driving shaft, pass motion to another root driven shaft that is positioned at the car body front end with chain-wheel mechanism then, can be because master and slave moving axis two ends respectively have along two wheels of flat guide operation, thus realize rotatablely moving of motor changed into the gyration of wheel, realize the walking of dolly along track.This coil of strip dolly under the driving of motor, can be realized transporting of coil of strip below 8 tons.But car body shake, creeping phenomenon then appear in coil of strip more than 10 tons, can't independently finish material loading.In order to realize the self-service volume that send of dolly, the crawling problems of car body when being necessary to solve low-speed heave-load.
Summary of the invention
Technical problem to be solved in the utility model is to overcome under the heavy load dolly to creep, can't independently finish a volume task difficult problem, provide a kind of simple in structure, reliable, can realize that the remote heavily loaded coil of strip of carrying transports dolly.
The technical scheme that solves the problems of the technologies described above is:
A kind of coil of strip transports dolly, it comprises car body, bracket, hydraulic motor, motor installation support plate, driving shaft, wheel, motor is installed support plate and is connected with car body, and driving shaft is connected with wheel, and its improvements are, its transmission mechanism is made up of little power transmission shaft, gear-box, gear-box is connected with car body, and large and small gear is arranged in the gear-box, and they are meshing with each other, the hydraulic motor axle is connected with pinion by little power transmission shaft, and gear wheel is connected with driving shaft.
Above-mentioned coil of strip transports dolly, and described hydraulic motor is the cartridge type motor.
The utility model has replaced chain gear transmission with gear drive, satisfying under the situation of functional requirement, make motor under higher output speed, to use, improved the operational efficiency of motor, avoided with low speed high torque hydraulic motor when low cruise, the situation that its power output reduces greatly, thus the difficult problem that dolly is difficult to even running under the low-speed heave-load solved.It is little to the utlity model has volume, in light weight, and control appliance is simple, reliable characteristics, and the corollary equipment that is suitable as cold rolling unit is promoted the use of.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Number in the figure is as follows: car body 1, bracket 2, hydraulic motor 3, motor are installed support plate 4, brief biography moving axis 5, gear-box 6, pinion 7, gear wheel 8, wheel 9, driving shaft 10, track 11, coil of strip 12
The specific embodiment
Show among the figure that the utility model is made up of car body 1, bracket 2, hydraulic motor 3, motor installation support plate 4, brief biography moving axis 5, gear-box 6, pinion 7, gear wheel 8, wheel 9, driving shaft 10.Wherein car body 1, bracket 2, hydraulic motor 3, motor installation support plate 4, driving shaft 10, wheel 9 all are prior aries, repeat no more.
Improvements of the present utility model are to make simple chain transmission of the prior art into the primary gear speed reducing pair.Improve the minimum operation speed of motor, promote the low speed bearing capacity.Show among the figure that transmission mechanism of the present utility model is made up of brief biography moving axis 5, gear-box 6, gear-box 6 is connected with car body 1, large and small gear is arranged in the gear-box 6, they are meshing with each other, and the hydraulic motor axle is connected with pinion 7 by brief biography moving axis 5, and gear wheel 8 is connected with driving shaft 10.
Other improvement is the cartridge type motor that original outer shaft extension motor is made into, promotes the bearing capacity of car body.
