Embodiment Construction

[0010] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0011] Such as figure 1 As shown, a kind of building elevator of the present invention comprises base 1, and base 1 is provided with load-bearing main chord 2, and the both sides of load-bearing main chord 2 is provided with hoisting cage 3, and the upper end of load-bearing main chord 2 is provided with pulley 4. There is a winch 5 inside the load-bearing main chord 2, and one end of the steel wire rope 6 on the hoist 5 passes through the pulley 4 to connect with the cage 3, and the load-bearing main chord 2 is provided with a limiter for limiting the travel distance of the steel wire rope 6 device.

[0012] The limiting device includes a proximity switch 7 and a stopper 8. The proximity switch 7 is fixed below the pulley 4 through a bracket 9...

Abstract

The invention discloses a lift for construction. The lift comprises a base, a bearing main chord is arranged on the base, a lift cage is arranged on each of the two sides of the bearing main chord, pulleys are arranged at the upper end of the bearing main chord, winches are arranged in the bearing main chord, the ends of steel wire ropes on the winches pass through the pulleys to be connected with the lift cages, and limit apparatuses for limiting the traveling distance of the steel wire ropes are arranged on the bearing main chord. According to the lift, the structure is simple, the design is ingenious, when the lift is used, proximity switches are off if retaining blocks touch the proximity switches during the rising of the steel wire ropes, motors of the winches are de-energized, and accordingly, the usage safety of the lift can be guaranteed, and the life safety of people is guaranteed. The lift is novel in design and beneficial to popularization and utilization, and the design scheme is creative.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a construction elevator. Background technique [0002] Elevators are one of the most important tools used to transport materials on construction sites. Existing elevators for building construction include self-elevating platforms, load-bearing main strings, cages, winches, steel wire ropes and pulleys. The load-bearing main strings are formed by stacking standard sections, and each standard section is made of circular steel pipes. The piece is at the top of the load-bearing main chord, the cage is connected to the load-bearing main chord through a pulley, and the self-elevating platform, the cage and the winch are connected by a wire rope. The elevator with this structure does not set a limit mechanism on the wire rope, so that when the operator does not pay attention and the cage is lifted to the top during lifting, if the wire rope is still running, the wire rope will be ...
