Description

Adjustable work frame

This creation is an improved structure of the work frame, especially a safety work frame suitable for confined space and with a folding function.

Both developing and developed countries are facing a phenomenon of excessive population concentration in the metropolitan area, whether it is engaged in commercial activities or development into a residential community, and the population is too concentrated, making the metropolitan area narrow and thick, relatively, in order to solve this one Phenomenon, most of the newly built buildings in the metropolitan area are high-rise buildings, which will increase the utilization of land, and high-rise buildings will be equipped with elevator equipment due to the need to move up and down.

The elevator equipment has the characteristics of saving time and labor, replacing the time-consuming and laborious task of simply walking the stairs in the past, providing quick action force, which is convenient for moving up and down in the building. There are many types of elevator equipment, such as passenger elevators, freight elevators, etc., due to elevators. It belongs to a very sophisticated instrument and equipment. It is frequently used and needs frequent maintenance to avoid major damage caused by malfunction.

In the elevator maintenance work, a single ladder was used in the past as a construction worker to carry out maintenance work support, but the stability of the single ladder is poor. For example, due to maintenance work, the body is excessively extended and the center of gravity is easy to shake, even Unstable and resulting in work safety accidents, and the single ladder can only be used as a climbing and leaning. It is impossible to stand on the top and work, which will limit the scope of work. Moreover, if you carry a hand tool with you, there is no platform for temporary release. It is more troublesome to maintain the operation. The above shortcomings have always been an urgent need for improvement in the relevant industry operators. However, there has not been a better solution for a long time. However, this creator has been engaged in the construction industry for many years and attaches great importance to the safety of on-site construction. Therefore, through continuous research and improvement, we have created a safe work rack that can provide on-site construction personnel with a safe and convenient handling.

Learn to work in a narrow space, the stability of the single ladder used Poor, the center of gravity is prone to shaking, and even unstable, resulting in work safety accidents, and the single ladder can only be used as a climbing and leaning, can not stand on the top of the work, will make the scope of work limited, and, such as carrying portable tools There is no platform for temporary release, which is troublesome in maintenance work. In order to improve the quality of construction and create a better safe construction environment, the creator has improved the shortcomings of the above-mentioned conventional techniques.

This creation provides an adjustable work frame that includes a safety flat The platform is provided with a joint portion on both sides of the safety platform. The safety platform is provided with a pivoting portion. The pivoting portion is substantially in the shape of a "ㄇ", wherein one side is an open surface, and the pivot portion can be a plurality of ladders, the top of the ladder is provided with a hinge device, the ladder is pivotally disposed on the assembly portion of the safety platform through the hinge device, and a support ladder is provided. The support ladder is provided with a hinge device. The hinge device is pivoted on a side of the safety platform, and a handrail is pivotally disposed on the plurality of pivot portions. The present invention is characterized in that the ladder, the support ladder and the handrail are pivotally connected. The handrail can be folded flat by the open surface of the pivoting portion and folded parallel to the safety platform, and the ladder and the supporting ladder can be adjusted and folded in the same direction as the handrail to achieve the handling and receiving. Stacking convenience.

The above-mentioned adjustable work frame utilizes the ladder and the support ladder to provide Providing a solid support, the creation is not easy to shake, the construction personnel can safely move up and down the creation to reduce the occurrence of accidents, and the safety platform of the creation has a larger standing than the conventional ladder. The space and the handrail are provided to enable the construction workers to stand and lean while standing, which increases the overall safety and, more importantly, the creation has the characteristics of being foldable, not only the present The creation has high maneuverability, and it is quite convenient to move and carry. When a large number of stacking, it also greatly saves the storage space required for stacking. In addition, this creation can be used for elevator maintenance work, and some narrow and limited work places. The present invention can also be used to perform the upper and lower operations, which greatly improves the shortcomings of the prior art; the following exemplifies a specific embodiment, and A detailed description of the drawings will enable the review board to have a better understanding of the technical features of the creation.
