Miniature lifter for building engineering

Abstract

The invention discloses a miniature lifter for building engineering. The miniature lifter comprises a mounting plate, a base, a jib and a bearing, wherein a support leg is mounted at the bottom of thebase, a foundation pillar is mounted at the top of the base through a triangular retaining bracket, an auxiliary pillar is mounted at the top of the foundation pillar through the bearing, a handle ismounted at the side far from the lifter at the top of the mounting plate through a bolt, the lifter is mounted at the side far from the handle at the top of the mounting plate, the jig is mounted atthe side far from the mounting plate at the top of the lifter, a mounting rack is mounted at the two sides of the jig, a brake is mounted at the top of the mounting rack through a brake bearing pedestal, a fixed pulley is mounted at the top end of the jig, a moving pulley is mounted below the fixed pulley through a rope, and a lifting hook is mounted below the moving pulley. The miniature lifter has the characteristics of simple structure, great safety effect and convenient mounting and dismounting. Under the action of a control button, the lifter ensures that a heavy object falls at a targetposition.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a small hoist for construction engineering. Background technique [0002] The hoist is a mechanical device that transports by changing the potential energy. Its power is generally large and its lifting capacity is strong. It completes the transportation process by dragging the flexible steel wire rope and the transported goods up and down by power machinery. In the prior art, The jib frame of the hoist is fixed on the base, and its power equipment is also installed on the base, so that the jib frame cannot be rotated. It is necessary to move the hoist as a whole before it can lift the heavy objects at the corresponding position. The operation is inconvenient. In addition, the hoist on the market is usually a one-piece structure, which is not convenient for the installation and disassembly of the machine. Moreover, there is no protective measure between the fixed pulley on th...

[0002] The hoist is a mechanical device that transports by changing the potential energy. Its power is generally large and its lifting capacity is strong. It completes the transportation process by dragging the flexible steel wire rope and the transported goods up and down by power machinery. In the prior art, The jib frame of the hoist is fixed on the base, and its power equipment is also installed on the base, so that the jib frame cannot be rotated. It is necessary to move the hoist as a whole before it can lift the heavy objects at the corresponding position. The operation is inconvenient. In addition, the hoist on the market is usually a one-piece structure, which is not convenient for the installation and disassembly of the machine. Moreover, there is no protective measure between the fixed pulley on the boom and the movable pulley below, which is easy to cause equipment damage. In addition, the hoist on the market does not have a storage box, which is not convenient for some disassembly tools or the placement of required items. At the same time, the hoist on the market has very few protection measures in terms of safety, which greatly increases the operating cost. The probability of safety accidents in the project increases the cost of repairing equipment and medical expenses for the injured in the accident
