Electric hoists are generally divided into chain hoists and wire rope electric hoists Currently, wire rope electric hoists are commonly used for handling heavy objects, mechanical welding, and the installation and movement of mechanical equipment. Existing wire rope electric hoists are usually combined with beams to move heavy objects.

However, it has some disadvantages: for example, the motor, reducer, and drum are relatively large and not compact enough; for example, although the reducer uses a planetary gear transmission structure, the structural design is not compact enough. Moreover, the existing wire rope electric hoists and the lower flange track of the main beam are mostly installed as a set. When used, different wire rope electric hoists need to be selected for main beams of different shapes, which is not convenient for conversion during construction site installation.

In order to solve the shortcomings of the existing technology, technicians have provided a new type of wire rope electric hoists It adopts the following technical scheme: a wire rope electric hoist, mainly including a frame and an electric hoist. Among them, the frame includes a support frame and a second support frame that are spaced apart; two parallel spaced support columns are slidably connected between the first support frame and the second support frame, and the trolley drive wheel is rotatably installed on the inside of the first support frame and the second support frame. The trolley drive wheel has gear teeth near one end of the first support frame, and two gears are rotatably provided on the inner sides of the first support frame and the second support frame, respectively. The trolley drive wheel meshes with the two gears, and a transmission guide rod is fixedly connected between the two gears. A motor is provided on the first support frame, and the transmission output shaft of the motor extends to the inside of the first support frame. The end of the transmission output shaft of the motor is fixedly connected to a gear. An adjustable screw rod is also fixed between the first support frame and the second support frame, and the adjustable screw rod is parallel to the support column. A pair of screw rods are correspondingly provided on each support column, and fixed nuts are provided on both sides of the first support frame and the second support frame. The electric hoist includes a housing, a drum is provided in the housing, two motors are provided below the drum, the transmission output shafts of the two motors cooperate with the drum through transmission gears, a wire rope is provided on the drum, a fixed pulley group is provided at the bottom of the first support frame, and the wire rope is fixed to the bottom of the second support frame through the fixed pulley group. A movable pulley device is provided on the wire rope. The trolley driven wheel is rotatably installed on the inner side of the first support frame and the second support frame, and guide wheels are respectively provided at both ends of the first support frame and the second support frame, and the guide wheels are vertically symmetrically arranged. One end of the support column is fixedly connected to the second support frame, and the other end of the support column is provided with a stop column. The top ends of the first support frame and the second support frame are respectively provided with hanging ears.

This wire rope electric hoists has the following advantages: 1. Through optimized design, the related support frames are slidably assembled on the support columns, and the spacing between the support frames can be adjusted by the screw rod to adapt to main beams of various specifications, thereby effectively improving the applicability of the frame, which can be applied to main beam tracks of various specifications, and the installation is convenient and quick, and the operation is simple, safe and reliable. 2. Through optimized structure, the modular design of the trolley is realized, so that the main components meet the general interchangeability of various specifications, and at the same time, the space is fully utilized, making the device more compact and more adaptable.
