Abstract

Manual riser relates to the lifting means field. Mainly aims to solve the problem that when a fire disaster happens in a high-rise building at present, escape personnel can fall down to be injured and killed due to the fact that bed sheets and clothes are not fastened and the like. When the high-rise building outer wall is subjected to high-altitude operation, the descending distance of an operator is not easy to master. The hoisting device comprises a shell, wherein an opening is formed in the bottom of the shell, a hoisting ring is fixed on the top of the shell, an upper grooved pulley is arranged at the upper part in the shell, a lower grooved pulley is arranged at the lower part in the shell, three guide wheels are arranged below the lower grooved pulley, a steel rope is wound in the grooves of the upper grooved pulley and the lower grooved pulley, and two ends of the steel rope extend out of the opening. The upper worm wheel is fixed on the upper grooved wheel, the lower worm wheel is fixed on the lower grooved wheel, a worm is arranged between the upper worm wheel and the lower worm wheel, and the upper worm wheel and the lower worm wheel are both meshed with the worm. The worm shaft is provided with a pinion, the bull gear is arranged on the shell, the pinion is meshed with the bull gear, and the rocking handle is arranged on the bull gear. The lifting device has the advantages of easy control of lifting speed and distance, safety and reliability.

Description

Manual lifter

The technical field is as follows:

the utility model relates to a lifting means field specifically is a manual elevating gear who is applied to all kinds of high altitude construction or eminence and flees.

Background art:

with the development of science and technology and the progress of times, high buildings are seen everywhere nowadays. When people live in high-rise buildings and encounter dangerous situations such as fire, how to safely and quickly escape is an important problem. At present, when a fire disaster occurs in a high-rise building, most people can escape by connecting bed sheets, clothes and the like and hanging down from windows, and if the escape personnel fall down and die due to the fact that the bed sheets and the clothes are not fastened or lack of strength and the like in the escape process, the situation sometimes occurs.

In addition, when the high-rise outer wall is decorated or glass is wiped for high-altitude operation, at present, most operators are hung by using a rope, and the operators descend by cooperating with the operators, so that the mode has the defects that the descending distance of the operators is difficult to master, the descending impulsive force is large, and the stability is poor.

The invention content is as follows:

the utility model aims to solve the technical problem that a manual lifter with the advantages of easily mastered descending distance, controllable descending speed, safety and reliability is provided.

The above object is achieved by: the steel rope winding device comprises a shell, an opening is formed in the bottom of the shell, a hanging ring is fixed to the top of the shell, an upper grooved wheel is mounted on the upper portion of the shell through a shaft, a lower grooved wheel is mounted on the lower portion of the shell through the shaft, three guide wheels are arranged on the left side and the right side below the lower grooved wheel side by side and are respectively a left guide wheel, a right guide wheel and a middle guide wheel, the three guide wheels are mounted in the shell through respective shafts, a steel rope is wound in an 8-shaped reciprocating mode in grooves of the upper grooved wheel and the lower grooved wheel, one end of the steel rope extends out of the opening in the bottom of the shell after passing through a space between the left guide wheel and the middle guide wheel, and the other end of the steel rope also extends out of the opening in the bottom of the shell after passing through the space between the right guide wheel and the middle guide wheel.

The upper worm wheel is fixed on the upper grooved wheel and is coaxial with the upper grooved wheel; the lower worm wheel is fixed on the lower groove wheel, the lower worm wheel is coaxial with the lower groove wheel, a worm is arranged between the upper worm wheel and the lower worm wheel, two ends of the worm extend out of the shell, the worm is connected with the shell through a bearing, and the upper worm wheel and the lower worm wheel are meshed with the worm.

A small gear is arranged on a worm shaft at the right end of the shell, a large gear is arranged on the shell below the small gear through a shaft, the small gear is meshed with the large gear, and a rocking handle is arranged on the large gear.

Firstly, slowly descending by using the device:

the hanging ring can be hung on indoor and outdoor columnar objects firmly, the safety belt of a descender is tied at one end of the steel rope, and an assistant person shakes the rocking handle to drive the large gear, the small gear, the worm and the worm gear to drive the upper groove pulley and the lower groove pulley to rotate in sequence, so that the steel rope falls at a proper speed.

After the first person falls to the ground, the safety belt of the second person is tied to the other end … of the steel rope, and when the last person descends, one end of the steel rope is hung on an indoor and outdoor columnar object firmly, so that the lifter is inverted, the safety belt of the second person is hung on the hanging ring, and the self-control speed of the device is lowered.

Secondly, the device is used for lifting:

hang rings firmly on indoor outer column object, wave the rocking handle, make the one end of hanging the rope fall to the ground, lifted person's safety belt is on the steel cable, lift the rocking handle off from the gear wheel, direct mount is in the left end of worm axle, and the helper directly waves the worm through the rocking handle, drives the worm wheel and rotates, and two ditch sheave rotates about the worm wheel drives, makes the steel cable drive the person that promotes rise.

The utility model has the advantages that: the speed of rising or descending can be adjusted through the speed of rocking the rocking handle, and the distance of rising or descending is easily controlled, safe and reliable, convenient to use, simple structure.
