Problems solved by technology

However, there are symmetrical pulley blocks at both ends of the platform, and the hoist needs to lift the pulley blocks at both ends. During the lifting process, the platform is often not at the same level due to time difference, and it is prone to overturning
In addition, after the platform is lifted to a certain height, it is necessary to work on it, especially in the high altitude, the movement of the platform will sway greatly, which will undoubtedly increase the danger of high-altitude operations

Embodiment 1

[0013] Example 1 as figure 1 As shown, a platform hoist for engineering in this embodiment includes a support rod 2 and a support base 1, and the support base 1 is fixed on the floor or other fixed surface at the top of the floor. Support bar 2 is hinged with support base 1, and now, support bar 2 can rotate around support base 1, can rotate to suitable position lifting platform when needing to use support bar 2, can turn back original position when not applicable. The support bar 2 is provided with a pulley block and a rope, and the rope pulls the pulley block through a power mechanism. The pulley block includes a movable pulley 4 and two fixed pulleys 3, the fixed pulley 3 is fixed on the support rod 2, the movable pulley 4 is fixed on the support rod 2, and the two fixed pulleys 3 and one movable pulley 4 form a triangular stable structure. It can ensure that the platform is always on the same level, and when the platform is displaced at a certain height, it can buffer the...

Embodiment 2

[0014] Embodiment 2 The difference between this embodiment and Embodiment 1 is that the movable pulley 4 is movable, that is, the movable pulley 4 is connected with the fixed pulley 3 through a rope to form a triangular structure. Now, the fixed pulley 4 can be adjusted in height, and according to the principle of the pulley block, the required power can be saved when the platform is lifted.

Abstract

The invention discloses an engineering platform hoist, which comprises a support rod and a support seat, wherein the support rod is hinged to the support seat. The engineering platform hoist is characterized in that a pulley block and a rope are arranged on the support rod, wherein the pulley block is pulled by the rope through a power mechanism; the pulley block comprises a movable pulley and fixed pulleys; the fixed pulleys are fixedly arranged on the free end part of the support rod; the movable pulley is connected with the fixed pulleys. According to the technical scheme, by the pulley block, the stability of a platform can be improved, and moreover, impact force on the hoist caused by the oscillation of the platform can be cushioned.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an engineering platform hoist. Background technique [0002] In engineering operations, it is necessary to lift the necessary engineering materials and people to a certain height to carry out the operations, including in high-rise buildings, when the cleaners of the walls clean the glass, they will use the platform hoist. Existing platform hoisting opportunities lift the platform to a certain height through ropes. The structure used is a pulley block structure, including fixed pulleys on the hoist part and fixed pulleys on the platform, and the traction of power lifts the platform. However, there are symmetrical pulley blocks at both ends of the platform, and the hoist needs to lift the pulley blocks at both ends. During the lifting process, the platform is often not at the same level due to time difference, and it is prone to overturning. In addition, after the platform is ...
