Embodiment 1

[0021] Example 1: Structural composition of an encircling single-girder crane trolley

[0022] In order to achieve the above purpose, the present invention mainly changes the structural form of the trolley fundamentally, changing from the original top-mounted or suspended type to a side-mounted type, placing the lifting hoist of the trolley on the side, and installing the running track of the trolley on the side of the single beam , carrying the lifting trolley, the whole structure of the lifting trolley is similar to a frame structure "hugging" on a single beam. The lifting trolley is mainly composed of the traveling beam 1 of the lifting trolley, the connecting structure frame 2, the pulley installation platform 3, the fixed pulley block 4, and the electric hoist 5. The traveling beam 1 of the lifting trolley is a box-shaped structure welded by steel plates, and the bottom is hollowed out. The running steel wheels are installed at the corresponding positions near the front ...

Embodiment 2

[0023] Embodiment 2 A method of using an encircling single-girder operating lifting trolley

[0024] 1. According to the cross-sectional size of the single beam and the installation position of the running track, determine the size of the connecting structure frame 2, assemble the lifting trolley and install it on the single beam, and can move back and forth along the running track under the traction of the driving force.

[0025] 2. Connect the control system and the power cord to make the electric hoist 5 in a workable state.

[0026] 3. The operation control system makes the hoisting trolley run above the hoisting object, the operation control system drops the hoisting wire rope, connects the wire rope and the hoisting object, and after confirming that it is firm, lifts the wire rope to lift the object, and moves the crane equipment to send the hoisting object to the designated place.

[0027] 4. Operate the control system to lower and land the hoisting object, and fine-tun...

Abstract

The invention belongs to an encircled single-beam operation crane carriage and an application method. The crane carriage is characterized by consisting of crane carriage walking beams, a connecting structure frame, a pulley mounting platform, a fixed pulley set and electric lifting blocks; the crane carriage walking beams are of box structures formed by welding steel; two crane carriage walking beams are symmetrically arranged left and right, and are connected by the connecting structure frame manufactured by pipes; the whole structure forms a closed annular structure; the electric lifting blocks are fixed in corresponding positions on the left and right sides of the closed annular structure; and the pulley mounting platform is welded under the electric lifting blocks for mounting the fixed pulley set. The crane carriage provides space for lifting, is suitable for all single-main-beam cranes, and improves the stability of single-main-beam crane carriages.

Description

technical field [0001] The invention belongs to a hoisting device, and relates to the design and use method of the hoisting device. Background technique [0002] At present, my country's lifting equipment mainly includes bridge cranes, gantry cranes, jib cranes, and light and small lifting equipment. In our engineering construction field, gantry cranes are widely used. The main girder application forms of gantry cranes are mainly divided into single main girder and double main girder. The main girder structure is mainly box girder, truss girder, honeycomb girder and other structures. The most commonly used ones are box girder and truss girder. Hanging from the lower part of the main beam. If the space of the hoisting place is relatively limited, it is also limited by the hoisting height, which brings a certain degree of inconvenience to the operation. Contents of the invention [0003] The purpose of the present invention is: for the hoisting trolley of single main gird...
