Abstract
The invention relates to lifting mechanism equipment, in particular to a loose chain detection and protection device, and aims to protect the chain lifting equipment of the lifting mechanism from damage in case a control switch is out of control. The device provided by the invention adopts the structure that a chain A and a chain B are arranged in the lifting mechanism to play the role of chain transmission; a detection device is arranged between the chains A and B; a bracket of the detection device is fixed by a locking screw rod; and a microswitch is mounted on the bracket and used for receiving chain signals. According to the invention, when being in the working state, the chains of the lifting equipment are in a tension state; and when the chains are in place and the control switch is out of control, the chains are in the tension state, the microswitch is triggered, a stop signal is sent to the lifting equipment, so that the chains stop falling, and accordingly the lifting equipment is protected, and the chain equipment is protected. The device provided by the invention has an important significance for protecting the lifting equipment.
Description
Technical field
The present invention relates to lifting mechanism equipment, particularly a kind of loose chain detects fender guard.
Background technology
Behind the jacking equipment carrying object; because object action of gravitation; chain is in exceptionally straight tension; when this moment, the malfunctioning state of master cock occured after the delivery article put in place chain will occur continues to descend; thereby the easy damage that causes jacking equipment; in order to prevent lifting mechanism damage to the chain jacking equipment when master cock is out of control, a kind of loose chain of special research and development detects fender guard.
Summary of the invention
The problem to be solved in the present invention is that the protection lifting mechanism prevents the technical matters that the chain jacking equipment damages when master cock is out of control.
In order to address the above problem, the technological means that the present invention adopts is:
Its structure comprises: be provided with sprocket wheel A sprocket wheel B and play driving chain in lifting mechanism, install checking device between sprocket wheel A and sprocket wheel B, the carriage of checking device is fixed with tie down screw, at carriage micro-switch is installed, and is used for the receive chain bars.
Jacking equipment chain of the present invention is lower in working order; chain is in tensioned state always; master cock is under out-of-control condition after chain puts in place; this moment, chain no longer was tensioned state; will touch micro-switch, send danger signal to jacking equipment, chain is no longer descended; thereby effectively protect jacking equipment, prevent the damage of chain equipment.It is significant to the protection of jacking equipment.
Description of drawings
Concrete structure of the present invention is provided by the following drawings.
Fig. 1, Fig. 2 are the organigrams that the loose chain of the proposition according to the present invention detects fender guard.
Sign among accompanying drawing 1 Fig. 2 represents respectively:
1, sprocket wheel A 2, checking device 2-1, micro-switch 2-2, carriage 2-3, tie down screw 3, sprocket wheel B 4, chain
The specific embodiment
As long as between sprocket wheel A and sprocket wheel B, install checking device is set as can be seen from Figure 1.Principle of work of the present invention: chain is in tensioned state in working order always; when master cock is malfunctioning after chain puts in place; this moment, chain no longer was tensioned state; pine can occur to fall; thereby will touch micro-switch, and send danger signal to jacking equipment, chain is no longer descended; it can effectively protect jacking equipment, prevents the damage of chain equipment.
The present invention is applicable to use the jacking equipment of chain gear, and it can effectively prevent the damage of elevating chain, and the protection jacking equipment has great importance.
Claims (1)
