Abstract

The invention relates to a heavy ascending-descending putting-releasing device. The device is characterized by comprising a support, wherein the lower portion of the support is connected with a through shaft, and the through shaft is sequentially and fixedly connected with a ratchet wheel, a shaft sleeve, a rope winding rotary cylinder and a gear from left to right; the left side of the upper portion of the support is connected with a driving shaft, the right side of the upper portion of the support is connected with a driven shaft, and the driving shaft and the driven shaft are concentrically arranged; the driving shaft on the inner side of the support is sequentially connected with a pull wheel, a two-way overrun clutch and an overrun clutch connecting plate from left to right; a proximity switch is arranged on one side of the inner side of the support, the other side wall of the support is connected with a friction ring, the driven shaft inside the friction ring is connected with a centrifugal plate, the centrifugal plate and the friction ring are concentric, a plurality of cylinder holes are formed and uniformly distributed in the centrifugal plate in the radial direction, and a cylinder pin is arranged in each cylinder hole in an inserted manner; the driven shaft is fixedly connected with a main gear; a clutch inserted in the overrun clutch connecting plate is arranged on the driven shaft; and the support is connected with a lifting lever shaft which is respectively connected with a lifting lever and a detent, and the middle of the detent is connected with an electromagnetic switch through a hinge pin. The heavy ascending-descending putting-releasing device can be widely applied to high altitude heavy transportation of various industries.

Description

technical field [0001] The invention relates to a lifting and retracting device, in particular to a heavy object lifting and retracting device for high-altitude operations. Background technique [0002] The retractable device for lifting heavy objects is generally controlled by controlling the speed of the motor or using other torsion devices to lift or lower the controlled weight. The use of this device to control the lifting is firstly dependent on external uncertain factors such as: electrical and power supply; secondly, the risk of the mechanism itself, such as: the failure of the speed controller, etc., to complete the lifting of heavy objects Work brings a lot of inconvenience. Contents of the invention [0003] In view of the above, the object of the present invention is to provide a heavy object lifting and retracting device that is safe, independent of the outside world, and can be unlocked and retracted flexibly. [0004] In order to achieve the above object, t...
