[0024] In order to make the purpose, technical solutions and advantages of this application clearer, the application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0025] In the relevant technology, T-beams are a commonly used structural form in bridge engineering. Their cross-section is T-shaped, with the protruding parts on both sides called flanges and the middle part called beam ribs or webs. T-beams have the advantages of saving concrete, reducing the deadweight of components, and improving spanning capacity, and are widely used in bridge engineering and other construction projects. During the construction of T-beams, flange formwork cranes are one of the key construction equipment, responsible for the important task of hoisting and fixing the T-beam formwork. Existing cranes are easily restricted by working space and have poor operational flexibility.

[0026] This embodiment provides a T-beam flange formwork crane, which can reduce the limitations of the working space and improve the convenience of operation.

[0027] See also Figure 1-Figure 2In this embodiment, a T-beam flange formwork crane includes a base 10 and a cantilever 20; wherein, the base 10 has a moving wheel 11, and the base 10 includes a support column 12; a lifting mechanism 21 is provided on the cantilever 20, and the cantilever 20 includes a sleeve 24, which is rotatably connected to the support column 12, and a raised abutting portion 25 is provided inside the sleeve 24, and the abutting portion 25 abuts against the top surface of the support column 12.

[0028] By adopting the technical solution of this embodiment, the lifting mechanism 21 on the cantilever 20 is driven to move on the top of the beam by the base 10, which can reduce the limitation of the working space. The friction between the sleeve 24 and the support column 12 can be reduced by utilizing the interference between the abutment portion 25 and the support column 12, making the rotation of the cantilever 20 easier.

[0029] In this embodiment, the base 10 is constructed as a whole into a rectangular frame shape, and four moving wheels 11 are provided at the bottom of the base 10. The moving wheels 11 support the base 10 and enable the base 10 to move smoothly on the top of the beam. The support column 12 is fixedly connected to the base 10. The support column 12 is constructed as a whole into a longitudinal cylindrical shape. The support column 12 and the base 10 are arranged vertically, and the support column 12 is arranged roughly at the center position of the base 10. In order to enhance the structural strength of the support column 12, four inclined reinforcement rods 13 are fixedly connected between the support column 12 and the base 10, and the four reinforcement rods 13 are symmetrically arranged on both sides of the support column 12.

[0030] It should be noted that the top surface of the support column 12 is a horizontal surface, and the top surface of the support column 12 is perpendicular to the axis of the support column 12 .

[0031] The cantilever 20 is constructed as a whole into an obtuse triangle structure, and a plurality of reinforcing rods are arranged inside the triangular structure. The sleeve 24 is fixedly connected to the obtuse angle of the cantilever 20. The sleeve 24 is constructed as a whole into a cylindrical shape with a closed upper end and an open lower end. The sleeve 24 is rotatably sleeved on the top of the support column 12, and the inner diameter of the sleeve 24 is equal to the outer diameter of the support column 12, that is, the inner circumferential surface of the sleeve 24 is in contact with the outer wall of the support column 12, and an abutment portion 25 is fixedly connected to the bottom of the inner cavity of the sleeve 24, and the abutment portion 25 is constructed into an arc shape along the cross section. The abutment portion 25 and the sleeve 24 are coaxially arranged, and the lower end of the abutment portion 25 contacts the top surface of the support column 12, which is used to reduce the contact area between the sleeve 24 and the top surface of the support column 12, thereby reducing the friction between the sleeve 24 and the support column 12, so that the cantilever 20 can be rotated relative to the support column 12 more easily.

[0032] In addition, a lifting mechanism 21 is fixedly connected to the left end of the cantilever 20. The lifting mechanism 21 can be a motor. A sling 23 is wound at the output end of the motor. The sling 23 passes around the guide wheel 22 at the right end of the cantilever 20 and is led downward. The motor is used to wind up the sling 23, thereby completing the lifting of the flange formwork.

[0033] It should be understood that by providing movable wheels 11 at the bottom of the base 10, the device can be moved on the top of the beam, which is convenient for adjusting the working position. The device can be placed movably on the top of the beam as a whole, which can reduce the limitation of the working space; through the rotation connection between the cantilever 20 and the base 10, the rotation and lifting operation of the flange formwork can be completed, which improves the convenience of operation; through the interference between the abutment part 25 and the support column 12, the friction between the sleeve 24 and the top surface of the support column 12 can be reduced, making the rotation of the cantilever 20 more convenient.

[0034] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
