The working process and principle of the device when in use are as follows:
when the lifting device is used, building materials to be lifted or tools for containing the building materials are connected to the bottom of the steel cable 6 in an initial state, the external motor connected with the axis of the scroll 5 is started, and the scroll 5 rotates at the moment to lift the building materials to a high position. At this time, the stall slider 75 is caught between the two movable rods 76, the two movable contacts 77 are not in contact, and the circuit cannot be connected.
In the process of rotation of the reel 5, the self-locking mechanism 4 on the outer side of the reel can be driven to synchronously rotate in the same direction, at this time, because the movable contact 77 is not contacted and does not generate a current path, no current exists in the current variant 44 electrically connected with the movable contact, the movable contact is liquid, and the limiting fixture block 45 can be extruded by the self-locking groove 2 and retracted into the sealing cavity 43 in the process of rotation of the self-locking mechanism 4, so that the normal rotation of the reel 5 and the self-locking mechanism 4 is not influenced.
Please refer to fig. 1, fig. 2, and fig. 4-5 for the above structure and process.

At this time, the stall slider 75 is subjected to a weight loss phenomenon, and the housing 71 and the internal structure fall synchronously, at this time, the stall slider 75 starts to move upwards relative to the housing 71 and the internal structure thereof, separates from the two movable rods 76, no longer limits the movable rods, and moves relative to the two movable rods 76 under the action of the elastic force of the return spring 78, at this time, the two movable contacts 77 are contacted, and the circuit is communicated.
Because the two movable contacts 77 are respectively and electrically connected with the four current variants 44 through the external circuit and are in a parallel circuit mode, namely, current exists in the current variants 44 at the moment, based on the characteristics of the current variants, the current variants 44 become solid at the moment, the limiting clamping block 45 cannot move towards the inside of the sealing cavity 43 and is clamped with the self-locking groove 2, and at the moment, the four self-locking mechanisms 4 can simultaneously limit the position of the reel 5, so that the reel cannot rotate, and the steel cable 6 and the building materials lifted by the same are ensured not to continuously descend.
Please refer to fig. 1, fig. 3, and fig. 6 for the above structure and process
In addition, because the two movable contacts 77 are respectively and electrically connected with the four current transformers 44 through the external circuit and are in a parallel circuit mode, the principle of the parallel circuit is utilized to know that when one current transformer 44 in the circuit fails and cannot normally work, the normal use of other current transformers 44 is not influenced, and the safety of the device in use is greatly ensured.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
