Abstract

A immortal gourd lifter adopts a single-head worm and a two-stage worm and worm gear to drive a large transmission ratio, and achieves very light and labor-saving hand chain tension (suitable for being controlled by old people and children). The winding drum is adopted for multi-layer winding, the lifting distance of the steel rope is realized by the steel rope, the lifting of high floors or deep wells is safer and more reliable, and the load capacity is not limited. The chain block solves a plurality of defects of a welding chain of the chain block in the prior art, uses the worm wheel for self-locking and reliable braking, overcomes the defects that a friction plate and a ratchet wheel used in the prior art are easy to wear and slip, thoroughly eliminates the fatal defect in the prior art, and realizes the popularization of the lifter with safety and reliability to meet wide requirements.

Description

Immortal gourd lifter

The technical field is as follows:

a lifting device for the magic gourd is composed of a dual-purpose lifting mechanism, which is composed of two stages of worm and worm gears for releasing or winding the steel cable on drum to make the hook at the end of steel cable hook the basket or bag for lifting the load. The worm wheel is driven by a single-head worm only by the worm; the worm wheel can not rotate automatically along with the rotation of the worm wheel, and can not descend for self-locking. The stopping positions of the lifting hook and the hanging basket at the tail end of the steel rope are controlled by a manual or electric hand chain. The fairy gourd replaces the defects of lifting by a welding chain and braking by a friction plate and a ratchet wheel in the prior chain block, and breaks through the unlimited lifting height and load.

Background art:

in the manual hoist, a main part is composed of a multi-stage gear transmission and a welding chain, and a plurality of welding chain rings are easy to break when one ring has quality defects, so that dangerous accidents are difficult to avoid (the chain is difficult to check and examine in use). Especially, the more chain links, the greater the danger, so that the lifting of high-rise or deep well with large distance cannot be solved, and the application range is limited.

The present invention features that single-headed worm is used to obtain self-locking braking of worm wheel, and the worm wheel is not rotated to fix the steel cable in required position.

The friction plate and the ratchet wheel mechanism of the chain block in the prior art are unsafe and reliable in braking and stopping position, and are subjected to a plurality of external factors such as abrasion degree (difficult to find), climate influence and environmental pollution, and the control and braking are always ineffective due to internal slipping.

The height and the carrying capacity of the immortal gourd are not limited by winding a steel rope on a winding drum, carrying objects at any height can be controlled to lift on the ground or on other floors, and particularly, the immortal gourd can be lifted to a safe place by a cloth bag made of a bed sheet at the emergency moment of an accident disaster. The immortal gourd is hooked on the beam of the high-rise building in advance and is controlled by the long bracelet, so that the operation is very simple, the old and the children can lift automatically, and the operation is safe and reliable.

The invention content is as follows:

a multifunctional electric or manual hoist features that a two-stage worm-gear is used for its forward and backward rotation, and a small manual chain is used to chain wheel, worm-gear is used to drive a drum coaxial with worm-gear via a two-stage worm-gear, and the drum is connected to steel cable hook. The calabash is hung with a beam or a tree steel nail for supporting and fixing, and the safety protection is realized for field exploration.

The chain block in the prior art has to be changed into the chain block of the invention due to a series of defects of a welding chain, thereby realizing obvious economic and social benefits, embodying technical progress and promoting better happiness of people. The immortal gourd has simple structure, easy manufacture, low cost, wide application and obvious benefit.

Description of the drawings:

FIG. 1 is a front view of a hoist for a immortal gourd

FIG. 2 is a plan view of a hoist

In fig. 1: (1) pulling a chain by hand; (2) a hand sprocket; (3) a worm; (4) a worm gear; (5) a worm; (6) a worm gear; (7) a steel cord; (8) a reel; (9) a bearing and a support frame; (11) the machine body and the supporting plate.

In fig. 1: the hand-pulling chain (1) controls the forward and reverse rotation of the hand chain wheel (2) to drive the worm (3) to rotate to move up or down for a stroke, the second-stage worm (sleeve) worm (5) and the second-stage worm wheel (6) (which can have the same module and tooth number as the first-stage machine part) connected in the shaft hole and the connected winding drum (7) rotate together through the rotation of the worm wheel (4), and then the steel rope wound on the winding drum is released to move down or is wound again to continue to rise.

When the hand chain (1) is not pulled, the worm gears stop rotating, the winding drum does not rotate, and the steel rope does not move, so that the tail end hook of the steel rope and the hanging basket or the cloth bag keep the previous station. When the hand chain (1) is continuously pulled or pulled reversely, the chain wheel (2) rotates continuously or reversely, and then the stable lifting operation is carried out.

In figure 2, a hand-pulling chain (1) and a hand chain wheel (2) are marked to be sleeved on a worm (3) to rotate a worm wheel (4), and because a second-level worm (5) is connected in a shaft hole of the worm wheel (4), the worm (5) is meshed with and drives the second-level worm wheel (6) and a winding drum (8) which is coaxially connected with the second-level worm wheel, namely a steel rope (7) is moved for a certain distance, and a tail end lifting hook drives a hanging basket cloth bag to lift. Because the winding drum can wind in multiple layers, the total length of the steel rope is enough to lift a high-rise distance or descend to the bottom of the well for deep well exploration. The hoisting weight and the lifting distance of the welding chain are limited due to the large and heavy structure of the prior art (chain block). Only the invention creates the light and convenient two-stage worm and worm wheel self-locking structure performance to overcome the problem of stable and safe lifting with large weight and large lifting distance which is difficult to realize in various prior arts by using the lighter and longer high-bearing steel rope. It creatively solves the problems that:

(1) the steel rope replaces a welding chain, so that the chain breakage accident caused by the quality defect of a certain chain ring is avoided. The lifting height and the lifting weight are greatly improved.

(2) The invention has the advantages of multiple functions, light weight, long steel rope, heavy load, easy manufacture, low cost, wide application and popularization, remarkable benefit and substantial achievement of initiating a plurality of breakthroughs.

Best mode of carrying out the invention:

the main parts of the lifter are a single-head worm and a phosphor bronze worm wheel, so that the lifter has the advantages of high precision, long service life, improved bearing capacity, adoption of oil lubrication or grease lubrication, low maintenance cost, capability of disassembling long and short chains at any time, no bending and twisting accidents of a single-rope steel rope and safe and reliable use (the defects of the steel rope are easy to check). Because the portable hanging basket is suitable for field use, the old and children can lift and fall by themselves, the hanging basket cloth bag can be prepared by themselves, and local materials can be obtained in emergency, so that the portable hanging basket is convenient and feasible.
