Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an auxiliary lifting device for H-beams. Background Technology

[0002] In various track engineering construction processes, H-beams are commonly used as the primary construction material. Due to their heavy weight and size, handling H-beams presents a significant challenge. Manual handling is difficult because the immense weight can lead to injury, while narrow passageways and limited space further restrict flexibility. Typically, manual handling involves tilting one end of the H-beam, placing a round bar underneath, and then pushing it. However, accurately controlling the direction of movement during this process is difficult, resulting in low overall efficiency. While mechanical assistance can alleviate some of the manual burden, the equipment design must accommodate the specific shape and size of the rails. Both manual and mechanical operation require a high degree of skill and precision. Therefore, regardless of whether manual handling or mechanical assistance is used to move the rails, it requires substantial manpower and resources, resulting in low construction efficiency and a high risk of injury. Utility Model Content

[0003] The purpose of this utility model is to provide an auxiliary lifting device for H-beams, which solves the problems of low handling efficiency, high cost, and easy injury to personnel in the existing technology of manual handling and mechanical assisted transportation of rails.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary lifting device for H-beams includes a lifting frame, a lifting arm, and rolling supports. The lifting frame is generally inverted U-shaped and is used to connect with the H-beam. The lifting arm is located on the top of the lifting frame and is used to operate the lifting frame. Two rolling supports are provided and are symmetrically arranged inside the lifting frame. The flanges of the H-beam slide on the rolling supports.

[0005] Preferably, support legs are provided at the bottom or outside of the lifting frame.

[0006] Preferably, auxiliary sleeves are fixedly installed on both sides of the lifting frame, and auxiliary connection holes are provided on the auxiliary sleeves; the top of the support leg is installed inside the auxiliary sleeve, and auxiliary mounting holes are provided on the support leg, and auxiliary connecting pins are inserted into the corresponding auxiliary connection holes and auxiliary mounting holes.

[0007] Preferably, the support leg includes a main support member, a bottom support rod, and an inclined support rod. The bottom support rod is fixedly installed at the bottom of the main support member, and two inclined support rods are installed between the bottom support rod and the main support member.

[0008] Preferably, the support leg is fixedly installed at the bottom of the lifting frame.

[0009] Preferably, the rolling support includes a transverse support rod and a rolling element, the rolling element being rotatably mounted on the end of the transverse support rod.

[0010] Preferably, the lifting frame includes a main support and an L-shaped support rod, with one L-shaped support rod adjustablely installed at each end of the main support.

[0011] Preferably, the lifting arm includes a support sleeve and a lifting rod, the lifting rod being adjustablely installed inside the support sleeve.

[0012] In this invention, the rolling support reduces friction during the movement of the H-beam, decreases thrust, and accurately controls the direction of movement, enabling rapid and convenient movement and improving handling efficiency. The rolling support design also effectively protects the flange surface of the H-beam, preventing scratches, wear, and other damage caused by direct friction with other objects during handling, thus ensuring the quality and appearance of the H-beam.

[0013] The overall structure is adjustable and can be disassembled and adjusted to accommodate various types of H-beams, greatly improving the versatility of the device. The entire adjustment process is convenient, allowing construction personnel to quickly complete the adjustment work without the need for complex tools or specialized skills, significantly improving work efficiency.

[0014] The support legs effectively distribute the weight of the H-beam, evenly transferring it to the ground. This prevents the H-beam from tipping over due to instability during lifting, providing a solid guarantee for the safety of operators. This stable support structure also reduces swaying of the lifting device during operation, making the lifting process of the H-beam smoother and further improving work efficiency and safety.

[0016] The present invention will be further described below with reference to the accompanying drawings: like Figure 1The illustrated auxiliary lifting device for H-beams includes a lifting frame 1, a lifting arm 2, and a rolling support body 3. The lifting frame 1 is generally U-shaped and is used to connect with the H-beam. The lifting frame 1 includes a main support 10 and L-shaped support rods 11, with an L-shaped support rod 11 adjustablely installed at each end of the main support 10. The main support 10 is a rectangular steel tube with pin holes. One end of the L-shaped support rod 11 is slidably installed inside the rectangular steel tube, and each L-shaped support rod 11 also has a pin hole. By passing a pin or bolt through the corresponding pin hole, the L-shaped support rod 11 is adjustablely connected to the main support 10 to accommodate different types of H-beams.

[0017] The lifting arm 2 is fixedly mounted on the top of the lifting frame 1 for operating the lifting frame 1. The lifting arm 2 includes a support sleeve 20 and a lifting rod 21, which is adjustablely installed inside the support sleeve 20. The support sleeve 20 is a rectangular or circular steel tube with limit holes.

A pin or bolt is passed through the corresponding pin hole to adjustably install the lifting rod 21 inside the support sleeve 20.

[0018] In a preferred embodiment, a lifting ring is fixedly installed at the top of the lifting rod 21, and the lifting ring is connected to a mechanical device to apply a lifting force to the lifting rod 21 to lift the H-beam.

[0019] Two rolling support bodies 3 are provided, and the two rolling support bodies 3 are symmetrically arranged inside the lifting frame 1. When the operator lifts the H-beam through the lifting frame 1 and the lifting arm 2, the flange of the H-beam slides on the rolling support body 3.

[0020] The rolling support 3 includes a transverse support rod 30 and a rolling element 31, the rolling element 31 being rotatably mounted on the end of the transverse support rod 30. In this embodiment, the transverse support rod 30 is fixedly mounted on the L-shaped support rod 11 by welding, and the rolling element 31 is selected as a bearing.
