Description

Mechanical device for assembling and disassembling lifting rolling gate

Technical Field

The utility model relates to a erection equipment of door, concretely relates to dress, dismouting device for shutter door.

Background

The rolling gate is greatly installed and used due to the characteristic of no occupation of ground space due to the upward rolling, and is particularly and often installed at doorways of ground shops, garages and the like. When the rolling gate is installed, several holes are drilled on the wall of the upper part of the door frame, the mounting bracket is fixed on the wall by nailing the expansion screw, and then the rolling gate is moved from the ground to the mounting bracket which is several meters away from the ground to be mounted. At present, people mainly adopt the following modes of upwards moving the rolling door when installing the rolling door.

The first mode of upward movement is carried by the most common people. Two ladders are arranged on the left and right sides of the door, and two workers climb up and down the ladder to assemble and disassemble the rolling door. The main disadvantages of this upward moving method are that a simple movable ladder is generally used, and some ladders are bounced, rocked and shaken, and the stability is not good. And secondly, according to the safety regulations of high-altitude operation, the operation is higher than two meters, and even if the high-altitude operation is carried out, a safety belt needs to be hung. However, as the ladder is loaded with heavy objects to continuously climb, the safety belt is difficult to hang up and down for use, and the safety belt cannot be used generally. Thirdly, the ladder for climbing heavy objects is not allowed, because the ladder is easy to get out of the safety problem because the ladder needs to be gripped by hands to stabilize a large rolling gate. Fourthly, the diameter of the door roll far exceeds the size of the shoulders of a person, and the person who carries the door roll on the shoulders needs extra effort to prevent the door roll from rolling down, so that the difficulty is increased. However, in view of cost, the labor is most used to climb the ladder directly. In addition, in order to reduce labor cost, in many cases, two persons go out to install and no person comes to the escalator, and once the persons fall off, the ladder is easy to fall down, the door is smashed, goods are rotten, and the persons are injured. Especially, the rolling doors with the height of nearly 4m or even more than 4m are installed, and the rolling doors with the height are correspondingly rolled to be larger, have larger volume and larger weight, are not easy to be stably placed on shoulders and climb to be higher, so that the rolling doors are not easy to be carried by young and strong people with quite good physical strength. In a word, the method has considerable toughness and danger, has certain criticality to the physical conditions of workers, reduces the universality of human resources, and needs workers with good physical strength and no fear.

The second way of moving up is to hang up by a hanging pulley fixed at a certain point. However, the pulley fixed at a certain point can only be lifted vertically and linearly to the vicinity of the roller shutter installation frame, and then people need to climb up and then transversely move the pulley to the roller shutter installation frame. And the hanging pulley can be conveniently suspended at a certain steel structure point when the hanging pulley is accidentally touched with the door below the steel structure. For most of doors under cement and brick wall structures, a hole needs to be drilled in the wall to install an expansion screw, a hook is arranged on the screw, and a hanging pulley is hung on the hook. One disadvantage of this approach is the difficulty in finding the hanging point on the wall. The horizontal ceiling and floor are often too high. The wall of the vertical surface is drilled with holes for hanging, and the rolling gate is easy to wipe the wall in the lifting process. Secondly, it is time-consuming and labor-consuming to additionally and specially drill a hole in the wall and add a suspension point, especially the load which can be borne by drilling a hole may not be enough, the construction cost is higher, and the hole is abandoned only by being hung, and the wall is damaged by drilling. Thirdly, the rolling gate is arranged on the bracket, and the bracket structure which is horizontally arranged blocks the straight upward movement of the rolling gate. The rolling gate is lifted from the side of the rolling gate support in the vertical direction, and the rolling gate needs to be transversely transferred to the mounting support by climbing a ladder after the rolling gate is lifted to the edge of the mounting support under the dangerous condition of hanging heavy objects on the top.

The third way to move up is to use a lifter like a fork lift to fork up the shutter door. Although it is very convenient to use at the moment of installing the rolling door, these machines have the problems of heavy weight, large volume and high cost. Such forklift lifts are generally relatively suitable for use by roller shutter door practitioners in large stores and the like, when a significant number of roller shutter doors need to be installed at one time. However, most of the time, the operation is scattered like installing a roller shutter at 20Km in the east city and installing a roller shutter at 30Km in the west city. If the large forklift is required to run in a city for only one door, the transportation and carrying costs become high. Since it is only a few minutes to carry a shutter door on hand. Because of the high production cost and the high carrying cost, the actual comprehensive efficiency of the machines is not high, so that the machines are difficult to popularize and use in a large quantity.

The fourth way to move up is to use an enlarged jack to lift the rolling door up. There are also some disadvantages like forklift lifts and there is a certain risk of tipping due to the relatively small chassis.
