Portable boom for construction hoist and its construction hoist

Abstract

The invention discloses a portable boom for a construction elevator and a construction elevator. The elevator includes a guide rail frame, a cage that can move along the length direction of the guide rail frame, a driving device installed on the cage for driving the cage to move, and The suspension rod installed on the top of the cage, the suspension rod includes a lower vertical rod which is rotatably arranged on the top of the cage around its own axis, an upper vertical rod which is fixedly connected to the upper end of the lower vertical rod, and one end is rotatably connected to the upper vertical rod. The boom on the top of the pole and the two ends are respectively detachably connected to the diagonal brace on the upper pole and the boom. The boom has two states of unfolding and folding. Support bracket between poles or upper poles. In the present invention, since the boom is rotatably connected to the upper pole, and the diagonal brace is detachably connected between the upper pole and the boom, the boom can be disassembled during transportation, which saves space. At the same time, a support frame is provided to effectively The phenomenon of tilting, bending and deformation of the boom is completely prevented.

Description

technical field [0001] The invention relates to the technical field of construction elevators, in particular to a portable boom for construction elevators and the construction elevator. Background technique [0002] Construction elevators are also called construction elevators for construction, and can also be called outdoor elevators and construction site elevators. They are often used in construction to carry people and cargo. They are mainly used for interior and exterior decoration of high-rise buildings, construction of bridges, chimneys and other buildings. The construction hoist mainly includes a guide rail frame and a cage that can move longitudinally along the guide rail frame. The cage is used to transport workers. A transmission plate is installed on the top of the cage close to the guide rail frame. A motor for driving the cage to move up and down is arranged on the drive plate. , reducer and other power mechanisms. The guide rail frame of the construction hoist...

AI Technical Summary

Problems solved by technology

[0003] At present, many suspenders usually adopt a one-piece structure, which causes great difficulties for installation, removal and transportation

And most of the suspenders are installed on the top of the cage through a socket structure. Usually, it is necessary to use a column with a large cross-section to ensure that it does not bend or deform during the hoisting process, resulting in a heavy weight of the suspenders, which is inconvenient to install and disassemble.

At the same time, the use of a socket-type structure to install the boom results in high friction between the boom and the base, causing varying degrees of wear on the boom and the base, and also makes the rotation of the boom difficult.
