A kind of double-track trolley

technical field

The utility model relates to a double-track running trolley.

Background technique

With the vigorous development of the logistics industry, the circulation of goods is becoming more and more frequent. In some occasions, manpower is still used to carry goods, and sometimes carts or other auxiliary means are used. However, in this way, on the one hand, the number of goods to be transported at one time is limited, and on the other hand, the handling speed is relatively slow, which prolongs the time spent on transporting goods. Time, especially when carrying heavy, bulky and indivisible items, the above method cannot be used. In response to the above situation, a kind of double-track operation trolley for carrying articles has appeared in the industry. However, the existing double-track trolleys have the following problems: 1. Complex structure, large volume, and small carrying capacity; 2. Low precision, unstable operation, and high noise; 3. Uneven force and short service life.

Contents of the invention

The technical problem to be solved by the utility model is to provide a double-track trolley with compact structure, small volume and large carrying capacity.

In order to solve the above technical problems, the utility model adopts the following technical scheme: a double-track trolley, including a hoisting and lifting mechanism, a trolley end beam device, a trolley device, a main beam device and an electrical device; the hoisting and hoisting mechanism includes Lifting motor, reducer, pull rod, reel device, brake seat, hydraulic block brake, pulley device, hook device, lifting height limiter and shaft overload limiter; the middle of the main beam device is installed inside There are pulleys and balance pulleys.

Further, a flange is provided between the lifting motor and the reducer.

Further, the lifting motor is provided with a motor shaft, the reducer is provided with a high-speed shaft, and an involute spline coupling is provided between the motor shaft and the high-speed shaft.

Further, a brake wheel and a hydraulic block brake are installed on the other end of the high-speed shaft.

Further, the reducer is provided with a low-speed shaft, and an involute spline is provided between the low-speed shaft and the reel device.

Further, the two ends of the reel device are provided with fixed end plates, and the fixed end plates are connected into one body through pull rods.

Further, a shaft type overload limiter is installed in the balance pulley device.

The double-track trolley of the utility model has the following advantages compared with the prior art because it is provided with a winch lifting mechanism, a trolley end beam device, a trolley device, a main beam device and an electrical device: 1. High precision, transmission Stable and low noise; 2. The total length of the double-track trolley is shortened to the greatest extent, and the structure is compact and the volume is small.

Detailed ways

In this embodiment, with reference to Fig. 1 to Fig. 3, the double-track trolley, including hoisting and lifting mechanism, trolley end beam device, trolley device 23, main beam device 14 and electrical device, is all of modular design, each part Self-contained, grouping is good. The hoisting and lifting mechanism includes a hoisting motor 30 (which can be equipped with YZ, YZR, YZPB, YPB and other types of motors according to customer requirements), a reducer 6 (there are 7 models for selection according to the lifting capacity and lifting speed) Configuration), pull rod 10, reel device 11, brake seat 5, hydraulic block brake 1, pulley device 12, hook device 13, lifting height limiter 20 and shaft overload limiter; the lifting motor A flange 15 is arranged between 30 and the speed reducer 6 . The lifting motor 30 is provided with a motor shaft, the reducer 6 is provided with a high-speed shaft, and an involute spline coupling is provided between the motor shaft and the high-speed shaft to shorten the connection length. A brake wheel and a hydraulic block brake are installed on the other end of the high-speed shaft. The reducer 6 is provided with a low-speed shaft, and an involute spline is provided between the low-speed shaft and the reel device. Both ends of the reel device 11 are provided with fixed end plates, and the fixed end plates are connected into one body through pull rods 10 . The other end of the reel is equipped with a four-position lifting height limiter, and the upper and lower limit positions are both limited by two gears.

The trolley end beam device is composed of an end beam, a driving wheel set, a driven wheel set, a three-in-one running reducer and a buffer. The end beam is made of cold-formed hollow rectangular steel; the wheel bearing seat holes at both ends of the end beam are bored as a whole; the wheel support bearings are all self-aligning roller bearings; It is necessary to remove the bearing seat and the end cover plate, and the wheel can be easily taken out from the end; the three-in-one reducer is directly set on the extension shaft of the driving wheel, and the fixing plate is connected and fixed with the fixing hole of the reducer with bolts on the top ; A rubber buffer is installed at both ends of the end beam.

The main beam device 14 is welded and formed by steel plates, and after the two ends are processed and drilled, it is locked and connected with the end beam device of the trolley with high-strength bolts to form a complete trolley; the middle of the main beam device 14 is installed with The pulley device and the balance pulley device 27, the shaft type overload limiter is installed in the balance pulley device 27.

The electrical device is equipped with different electrical control devices according to different lifting and running motors; the operating system includes flashlight door operation (ground operation), cab operation, and remote control operation.

The double-track trolley of the utility model has the following advantages compared with the prior art because it is provided with a winch lifting mechanism, a trolley end beam device, a trolley device, a main beam device and an electrical device: 1. High precision, transmission Stable and low noise; 2. The total length of the double-track trolley is shortened to the greatest extent, and the structure is compact and the volume is small.

The utility model has been described in detail above. The above description is only a preferred embodiment of the utility model. When it cannot limit the scope of the utility model, all equivalent changes and modifications made according to the scope of the application should be Still belong to the scope covered by the present utility model.
