Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a transition beam structure and an introduction system of a tower crane. Background Art

[0002] The slewing mechanism is installed between the crane and the tower body of the tower crane, so that the tower crane can achieve 360-degree rotation during work, improve the flexibility and operation capacity of the tower crane during work, expand the working range, and thus improve work efficiency. When the slewing mechanism is installed on the tower body, a transition beam structure is installed between the slewing mechanism and the tower body to fix the tower body and the slewing mechanism, and the introduction system (including the introduction beam, introduction trolley and other components) will be fixed on the transition beam structure as a guarantee of the safety and stability of the tower crane.

[0003] However, the current transition beam structure and introduction system dimensions are basically fixed. The same transition beam structure and introduction system can only be used on tower cranes of corresponding dimensions. This means that when installing tower cranes of different models and specifications, only transition beam structures and introduction systems of corresponding dimensions can be produced, which increases production and manufacturing costs. In addition, the maintenance and management costs and difficulty of the transition beam structure and introduction system will also increase. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a transition beam structure and an introduction system for a tower crane, aiming to solve the problem of increased production and manufacturing costs due to the need to produce transition beam structures and introduction systems of corresponding sizes according to the models of tower cranes when different models of tower cranes need to be used.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is: a transition beam structure and an introduction system of a tower crane, including a transition beam structure and an introduction system, the transition beam structure includes a symmetrical first transition beam and a second transition beam, the first transition beam and the second transition beam include a main beam and a connecting part, the connecting part is fixed at both ends of the main beam to form a C-shaped transition beam, the ends of the connecting parts of the first transition beam and the second transition beam are provided with mounting blind holes, and also include bolts matching the mounting blind holes, nuts are threadedly connected to the bolts, the introduction system includes an introduction beam, an introduction trolley, and a pulley assembly, one end of the introduction beam is fixedly installed at the bottom of the transition beam structure, the pulley assembly is fixedly installed at the other end of the introduction beam, a slide groove is opened on the side wall of the introduction beam, and the wheels of the introduction trolley are slidably installed in the slide groove.

[0006] The principles of this solution are:

[0007] The transition beam structure is divided into a symmetrical first transition beam and a second transition beam, the first transition beam and the second transition beam both include a main beam and a connecting portion, and the connecting portion is fixed at both ends of the main beam to form a C-shaped transition beam, bolts are fixedly installed on the connecting portion of the first transition beam and the second transition beam, and nuts are used to fix the bolts together, the first transition beam and the second transition beam are fixed together to form a transition beam structure, the transition beam is installed between the tower body and the slewing mechanism of the tower crane to achieve the fixation of the tower body and the slewing mechanism, and the introduction beam is fixed at the bottom of the transition beam structure, after the standard section of the tower crane or other heavy objects are transferred to the introduction beam through the boom, the standard section or heavy objects are pulled onto the tower body through the introduction trolley; when using different models of tower cranes, the models of the slewing mechanism and the tower body require the use of corresponding different models of transition beam mechanisms and introduction systems, at this time, the size of the transition beam structure is changed by adjusting the length of the bolts between the first transition beam and the second transition beam, thereby achieving the purpose of reducing costs.

[0008] The beneficial effects of this program are:

[0009] The first transition beam and the second transition beam are fixed together by bolts and nuts to form a transition beam structure. The length between the first transition beam and the second transition beam can be adjusted according to different types of tower cranes, so that the transition beam structure can adapt to different types of tower cranes, thereby reducing production costs.

[0010] Furthermore, a through groove is provided in the connection part, and the through groove horizontally penetrates the connection part. During installation, the staff can hold the first transition beam and the second transition beam through the grass, which is convenient for maintaining the stability of the first transition beam and the second transition beam and facilitating installation.

[0011] Furthermore, a support rod is fixedly installed between the main beam and the connecting part. The installation of the support rod can enhance the stability between the main beam and the connecting part.

[0012] Furthermore, a protective layer is provided on the outer wall of the transition beam structure and the introduction system. Since the working environment of the tower crane is relatively harsh, the transition beam structure and the introduction beam are susceptible to corrosion and wear, which can easily lead to a decrease in safety performance and cause safety accidents. The provision of the protective layer can extend the service life of the transition beam structure and the introduction system.

[0013] Furthermore, a washer is provided between every two nuts on the bolt. The provision of the washer can enhance the tightness of the connection between the bolt and the nut, prevent loosening, reduce wear between the bolt and the nut, and increase the contact area between the bolt and the nut, thereby improving stability.

[0014] Furthermore, the introduction beam includes two beams, the two beams are arranged in parallel, and a connecting rod is fixedly installed between the two beams fixedly installed at the bottom of the transition beam structure. The setting of the connecting rod fixes the distance and position between the two beams to ensure the stability of the introduction beam. BRIEF DESCRIPTION OF THE DRAWINGS

The mounting blind hole also includes a bolt 106 that cooperates with the mounting blind hole. The bolt 106 can be fixedly installed in the mounting blind hole by interference fit between the bolt 106 and the mounting blind hole or by integral molding. A nut 107 is threadedly connected to the bolt 106, and a washer is arranged between every two nuts 107. A through groove 109 that horizontally penetrates the connecting portion 104 is opened on the connecting portion 104 of the first transition beam 101 and the second transition beam 102, and a support rod 105 is fixedly installed between the main beam 103 and the connecting portion 104 by welding or integral molding. The installation of the support rod 105 can improve the stability of the transition beam structure.

[0022] The introduction system 201 includes an introduction beam 202, which includes two beams. The two beams are arranged in parallel, and a connecting rod is fixedly installed between the two beams by welding or integral molding. The installation of the connecting rod fixes the two beams of the introduction beam 202 together to ensure the stability of the introduction beam 202. One end of the introduction beam 202 is fixedly installed at the bottom of the transition beam structure by bolts 106 or snap-fitting. A pulley assembly 204 is fixedly installed at the other end of the introduction beam 202, and a slide groove 205 is opened on the side walls of the two beams.
