Abstract

The present invention discloses a hoisting and leveling device for a large-span steel structure member. The present invention belongs to the technical field of construction engineering, and in particular, relates to a hoisting and leveling device for a large-span steel structure member. It comprises an adjusting cylinder, one side of the adjusting cylinder is provided with an upper lifting ring, the other side of the adjusting cylinder is slidably connected with an adjusting device, the other side of the adjusting device is threadedly connected with an adjusting bolt, and the other side of the adjusting bolt is provided with a lower lifting ring at the top. The large-span steel structure member can be fine-tuned. When the adjusting device is rotated up and down to adjust the adjusting bolt during fine-tuning, it will not need one side to rotate when connected with an ordinary bolt and nut. If it rotates, the fine-tuning will cause the lifting rope to rotate during hoisting. When the adjusting bolt is adjusted up and down, the present invention only needs to rotate the leveling device, and will not cause the lifting rings at both ends to rotate.

Description

A hoisting and leveling device for large-span steel structure components

Technical Field

The invention belongs to the technical field of construction engineering, and in particular relates to a hoisting and leveling device for a large-span steel structure component.

Background Art

The present invention is mainly used for leveling of large-span steel structure components during hoisting and installation, reducing the difficulty of hoisting and improving the installation quality. With the continuous development of the times, the forms of building structures are becoming more and more diverse. Steel structures are gradually replacing traditional cast-in-place structures and are widely used because of their advantages such as light weight, rich shapes and fast installation speed.

At present, the main installation method of steel structure is hoisting, which is usually carried out by automobile crane or tower crane. However, when steel structure is installed by hoisting, it is difficult to control the installation speed and precision, and it requires high level of hoisting machinery operators and installation personnel. The installation speed is slow and the construction quality is difficult to control.

The installation of steel structures requires very high precision, but in the actual installation process, it is difficult to control the quality of steel structure installation. The main reasons are: most steel structures are installed by welding or high-strength bolts. When the hoisting method is used, it is impossible to achieve fine adjustment of the installation, resulting in difficulties in installation alignment; after the steel structure is aligned, when welding or high-strength bolts are used, the components need to remain relatively static, but the components are greatly affected by the environment in the air, and the connection quality is difficult to control.

The present invention is a technical solution to various problems that arise during the hoisting and installation of such steel structures. The invention invents a hoisting and leveling device for large-span steel structure components, which can achieve fine-tuning of large-span steel structure components. When fine-tuning, the adjustment device is rotated up and down to adjust the adjustment bolts. When moving, it will not be like the connection with ordinary bolts and nuts, which requires one party to rotate. If it rotates, the fine-tuning will cause the lifting rope to rotate during hoisting. When adjusting the adjustment bolts up and down, the present invention only requires the leveling device to rotate, and the lifting rings at both ends will not rotate.

Summary of the invention

The technical problem to be solved by the present invention is that the fine adjustment of the hoisting components cannot be achieved during the hoisting and installation of the steel structure.

In order to solve the above technical problems, the present invention adopts the following technical solutions: a hoisting and leveling device for a large-span steel structure member, comprising an adjustment cylinder, an upper lifting ring is provided on one side of the adjustment cylinder, an adjustment device is slidably connected to the other side of the adjustment cylinder, an adjustment bolt is threadedly connected to the other side of the adjustment device, a lower lifting ring is provided on the top of the other side of the adjustment bolt, and the adjustment device is provided with a sliding mechanism matched with the adjustment cylinder. The adjustment bolt is inserted into the adjustment cylinder, the upper part of the adjustment device has a through hole that matches the outer wall of the adjustment cylinder, and the lower part of the adjustment device has a through hole that matches the adjustment bolt, and there are threads on the through hole. The adjustment device is integrally formed and more solid.

The adjusting cylinder is inserted into the inner side of the upper part of the adjusting device. The outer surface of the tail of the adjusting cylinder is provided with a first outer groove, and the lower part of the first outer groove is provided with a second outer groove. The upper end of the inner part of the adjusting device is provided with a first inner groove matched with the first outer groove, and the lower end of the inner part of the adjusting device is provided with a second inner groove matched with the second outer groove. The outer walls of the first inner groove and the second inner groove are provided with fixing holes, and the fixing holes are provided with a sliding mechanism matched with the first outer groove and the first inner groove. The second inner groove includes a sliding cylinder, and a spring is provided inside the sliding cylinder, and fixed points for fixed connection are provided on both sides of the spring. When the adjusting cylinder is inserted into the adjusting device, the first outer groove is parallel to the first inner groove, forming a space, and the sliding mechanism slides in this space. When the adjusting cylinder is inserted into the adjusting device, it can fix the adjusting cylinder up and down, and can also make the adjusting cylinder rotate on the adjusting device.

The through hole where the adjusting device is connected to the adjusting bolt is provided with an internal thread, and the middle and upper part of the adjusting bolt is provided with an external thread, which is adapted to the internal thread. The adjusting bolt is threaded to connect the adjusting bolt, and one end of the adjusting bolt connected to the adjusting cylinder can rotate idly, so that the adjusting bolt can be translated up and down.

The upper fixing planes are arranged on both sides of the lifting ring, and the lower fixing planes are arranged on both sides of the lifting ring. The upper and lower fixing planes are more convenient for connection.
