New type lever hoist

Abstract

The invention relates to the technical field of hoisting equipment, in particular to a novel lever hoist. The novel lever hoist comprises a front wall board and a rear wall board which are oppositely arranged front and back in a spaced mode; a hoisting chain wheel is arranged between the front wall board and the rear wall board; a long shaft extending out in an anteroposterior direction is connected on the hoisting chain wheel; a part, positioned at the front side of the front wall board, of the long shaft is connected with a clutch device; a wrench device which is connected with the front wall board and matched with the clutch device is arranged outside the clutch device; an upper supporting rod is connected on a position, above the hoisting chain wheel, between the front wall board and the rear wall board; a hanger is connected on the upper supporting rod; a hoisting chain which droops towards a position below left and right sides of the hoisting chain wheel is wound on the hoisting chain wheel; one end of each of left and right sides of the hoisting chain is used as a load end which is connected with a lifting hook; and one end of the other side of each of left and right sides of the hoisting chain is used as a loose end which is connected with a limiting pull ring; and a guide chain device is further arranged between the front wall board and the rear wall board. The novel lever host is safe and stable in use, high in loading cavity, not liable to damage, high in fluency and good in guide effect.

Description

Technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a novel lever hoist. Background technique [0002] The lever hoist is to manually pull the wrench by manpower and use the principle of leverage to obtain a linear traction matching the load, thereby driving the heavy object to move up and down. Due to the small size and light weight of the lever hoist, it is very convenient to carry and operate. It is suitable for small tonnage heavy objects. Due to the structure of the existing lever hoist, the force distribution is not optimized enough, and the load capacity is still It is not strong enough, it is not stable or smooth during operation, it is easy to cause damage to the load or the lever hoist itself during the operation, and the service life is not long enough, and the force distribution such as the chain guide device is not optimized enough, and the load capacity is not enough. Strong, not stable enough or smooth during ...

Problems solved by technology

Due to the small size and light weight of the lever block, it is very convenient to carry and operate, and it is suitable for heavy objects with a small tonnage. The existing lever block, due to its own structure, is not optimized for force distribution, and its load capacity is still low. Not strong enough, not stable or smooth enough during operation, easy to cause damage to the load or the lever hoist itself during operation, the service life is not long enough, and the force distribution of the chain guide device is not optimized enough, and the load capacity is not enough Strong, not stable enough and not smooth enough during operation, it is easy to cause damage to the load or the lever hoist itself during operation, the service life is not long enough, the guiding performance is poor, the guiding effect is not good, and it is easy to increase the deflection, which not only affects the operation And there are security risks
