Mechanical spreader for automatic locking and unlocking of the tooling plate

Abstract

The invention discloses a mechanical hoist for automatically locking and unlocking a tooling plate, which belongs to hoisting tools, and its structure includes a hoisting cage and lock buckles, and each lock buckle includes a lock body, a lock tongue, a return tongue, a reset tongue and a spring pull rod , self-locking rod, connecting rod, upper rotating shaft, lower rotating shaft and bearing, the spring pull rod between the upper rotating shaft and the lower rotating shaft is provided with a connecting shaft, the connecting shaft is connected with the connecting rod, and the rear end of the return tongue is provided with an upper driving rod , the rear end of the lock tongue is provided with a lower lever, the lower end of the connecting rod is hinged with the lower lever, the upper end of the connecting rod has a strip hole, the upper lever passes through the strip hole, the rear end of the reset tongue is connected to the self The locking rods are connected, the front inner side of the self-locking rod is provided with a locking pin, and the return tongue at the bottom of the locking pin is provided with a returning groove matched with the locking pin. The invention has the characteristics of no need for manual or electric, pneumatic and other auxiliary power; avoiding the danger of manual operation and the low life of other auxiliary components such as electric and pneumatic.

Description

technical field [0001] The invention relates to a hoisting tool, in particular to a mechanical hoisting tool for automatically locking and unlocking a tooling plate. Background technique [0002] In the chemical field of dangerous goods, for the convenience of maintenance, the equipment is installed on the standard tooling board. When the tooling board and its equipment are hoisted, ordinary spreaders often need to be locked and unlocked manually, or with the help of additional power such as pneumatic and electric power to achieve locking and unlocking. In the dangerous chemical environment, operation and maintenance are very dangerous, and personnel are often not allowed to enter casually. Parts made of organic products in electric and pneumatic components are not allowed to be used easily, and even if they are forced, their service life is often very short. Now mainly rely on the above two ways to work. Danger, and low life have been plagued by the use of units. Conte...
