Description

Attached self-elevating aerial work platform

(1) Technical field:

The invention relates to high-altitude operation fields such as building construction, building exterior decoration and building cleaning, bridge construction, dam construction, factories and mines, and specifically relates to an attached self-elevating high-altitude operation platform.

(two) background technology:

With the sustained and high-speed development of my country's national economy, my country's large-scale infrastructure construction and industrial and civil engineering projects are being carried out at an unprecedented speed, and this development trend is becoming stronger and stronger. For civil engineering structures, such as high-rise and super high-rise building structures, bridge structures, dams, etc., it is necessary to set up an aerial work operation platform during construction to solve the needs of operators for aerial work, stacking of some production materials and other construction techniques; Existing buildings, such as high-rise and super high-rise buildings, are undergoing facade maintenance, re-decoration, and building exterior cleaning. Especially for large-area glass curtain walls, it is also necessary to build high-altitude operation platforms outside the building; aerospace and some other factories and mines In production, it is often necessary to set up an aerial work operation platform. Therefore, objectively speaking, many industries in our country need an advanced, efficient and fast operating platform for high-altitude operations in the production process.

At present, there are two methods used when building aerial work platforms in the construction industry and other industries:

(1) Scaffolding method. Its characteristics are: ancient, backward, very low degree of automation, time-consuming construction, long cycle, and considerable wear and tear of steel pipes.

(2) Electric control attached lifting scaffolding. The equipment is based on the principle of guide rail guide seat hydraulic climbing frame, combined with the construction technology of the hanging basket, the whole equipment is suspended on the cast-in-place structure under construction through wall bolts and attachment components. During the construction of the main structure, the equipment needs to complete three important steps every time it is climbed: the installation of the upper attachment device, the climbing of the H-shaped guide rail and the climbing of the entire frame. Hanging basket technology is used in the external decoration of the structure. Two different working methods are used for equipment climbing during the main structure construction and exterior decoration construction, and the installation of the hanging basket working device needs to be completed with the assistance of external lifting equipment. This method mainly has the disadvantages of complex operation; poor stability of the hanging basket, large swing when subjected to wind load, and difficult control; narrow applicable surface, large number of attachment devices, and high technical requirements. At the same time, since the equipment itself has no lifting function, it cannot carry out vertical transportation of raw materials.

(3) Contents of the invention:

In order to overcome the deficiencies in the prior art such as complex operation, poor stability of the hanging basket, narrow applicable surface, large number of attachment devices, and high technical requirements, the present invention proposes an attached self-elevating aerial work platform.

The entire attachment bracket is anchored and connected with the building structure through the attachment rod, so as to ensure the stability of the attachment bracket structure.

Stand base. The support base includes a base, a support mechanism and an adjustment mechanism. The support base bears the main load of the entire platform, and adjusts the support height and the horizontal state of the base through the transmission device.

lifting device. The lifting device adopts the lifting device of the aerial work platform driven by the main hook and the auxiliary hook, including the main lifting mechanism and the auxiliary lifting mechanism. The main lifting mechanism includes the main hook, the auxiliary hook, and the hydraulic system; the auxiliary lifting mechanism includes the main hook and the auxiliary hook. The main lifting mechanism and the auxiliary lifting mechanism are respectively installed in the control platform section, and are connected to each other through hydraulic pipes to realize the synchronous work of the main and auxiliary lifting mechanisms.

safety devices. The safety device is used for the further safety guarantee of the platform's rising, falling and static construction status, and is located on the control platform section. The present embodiment adopts a wedge safety device, which includes a wedge brake, a wedge controller and a wedge groove. A "Z" shaped wedge plate is fixed on the bottom of the control platform section truss, which forms a wedge groove together with the vertical surface of the attached bracket; the wedge brake is fixed under the control platform section truss through the bracket, and the wedge The block controller is fixedly installed in the middle of the control platform section truss, and requires the friction ratchet of the wedge controller to be in contact with the vertical surface of the attachment bracket.

The invention is equipped with two sets of lifting devices, which are respectively located on both sides of the platform and fixed on the standard joints of the lifting gantry platform.

Since the present invention is essentially different from the prior art in terms of lifting principle and structure, it has a larger scope of engineering use than the prior art, and can be used in the construction and exterior of the main structure of a new structural system (buildings, bridges, dams, etc.). Decoration can also be used for maintenance, renovation, redecoration, building cleaning, etc. of existing buildings, and can build aerial work platforms in aerospace and other enterprises, which can improve construction efficiency, reduce construction period, and improve construction mechanization level. role.
