Abstract
Description
Technical Field
[0001] This utility model relates to the field of transfer equipment technology, specifically to a hoisting support for π-shaped beams. Background Technology
[0002] In mining, tunnel construction, and large-scale infrastructure development, π-shaped beams are widely used as a key support component for temporary or permanent support of tunnel roofs and sidewalls. Their unique "π"-shaped structure (top beam and bottom side extensions) gives them excellent load-bearing capacity, but also places demands on hoisting techniques.
[0003] Traditional hoisting methods typically use steel wire ropes for securing the beam. However, this approach presents several technical challenges in practical applications. For instance, during the binding process, uneven friction distribution across different parts of the steel wire rope can easily cause the π-shaped beam to tilt. This is especially problematic during long-distance transport or high-altitude operations, significantly increasing the likelihood of beam swaying and posing a substantial safety risk. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing a hoisting support for π-shaped beams that not only facilitates workers in lifting and transporting π-shaped beams to their intended location but also improves the stability of the device during the movement of the π-shaped beams.
[0005] This utility model is achieved through the following technical solution: a hoisting support for a π-shaped beam is provided, including a U-shaped hanging body. Vertical plates are fixed to the left and right side walls of the U-shaped hanging body. Two horizontal bars are provided on the inner side walls of the vertical plates, respectively located on the front and rear sides of the U-shaped hanging body. The horizontal bars extend laterally in the left-right direction and pass through the vertical plates. Two vertical plates are fixedly connected to the inner side walls of the horizontal bars, distributed laterally in the front-rear direction. A rotating wheel is provided inside the U-shaped hanging body and rotatably connected to the front and rear vertical plates. A connecting plate is fixedly connected to the outer side wall of the horizontal bars. A spring is sleeved on the horizontal bars and fixedly connected to the connecting plate and the vertical plates. A limiting rod is fixedly connected to the inner side wall of the connecting plate. The end of the limiting rod away from the connecting plate extends laterally in the left-right direction, passes through the vertical plate, and is flush with the inner side wall of the rotating wheel. The bottom of the limiting rod is flush with the bottom of the rotating wheel, and the top of the limiting rod is flush with the horizontal axis of the rotating wheel. The vertical distance between the limiting rod and the inner side wall of the top rod of the U-shaped hanging body is consistent with the vertical height of the side extension plate of the π-shaped beam.
[0006] In use, this utility model features a U-shaped hanging body with vertical plates fixed to its left and right side walls. Two horizontal bars are mounted on the inner walls of the vertical plates, located on the front and rear sides of the U-shaped hanging body respectively. These horizontal bars extend laterally in the left-right direction and pass through the vertical plates. Two vertical plates, distributed laterally in the front-back direction, are fixed to the inner walls of the horizontal bars. A rotating wheel, rotatably connected to the front and rear vertical plates, is located inside the U-shaped hanging body. A connecting plate is fixed to the outer wall of the horizontal bars, and a spring, fixed to the connecting plate and vertical plates, is fitted onto the horizontal bars. A limiting rod is fixed to the inner wall of the connecting plate, with one end of the limiting rod extending laterally in the left-right direction, passing through the vertical plates, and connecting with the rotating wheel. The inner walls are aligned, the bottom of the limiting rod is aligned with the bottom of the rotating wheel, and the top of the limiting rod is aligned with the horizontal axis of the rotating wheel. In use, a U-shaped hanger is placed every 0.5 meters on the π-shaped beam, and the U-shaped hangers are controlled to move upwards, causing the π-shaped beam to enter the U-shaped hanger. This causes the side extension plates on the left and right sides of the bottom of the π-shaped beam to contact the side wall of the rotating wheel inside the U-shaped hanger, away from the crossbar. Driven by the side extension plates on the left and right sides of the bottom of the π-shaped beam, the rotating wheel rotates downwards, and the crossbar, driven by the vertical plate and the rotating wheel, and pushed by the side extension plates on the left and right sides of the bottom of the π-shaped beam, moves within the vertical plate in a direction away from the π-shaped beam. The connecting plate moves away from the π-shaped beam along with the vertical plate, stretching the spring. The limiting rod also moves away from the π-shaped beam within the vertical plate along with the connecting plate. This causes the side extension plates on the left and right sides of the bottom of the π-shaped beam to move below the limiting rod via the rotating wheel and the limiting rod, contacting the inner wall of the U-shaped hanging rod. At this point, because the rotating wheel and the limiting rod are no longer in contact with the side extension plates on the left and right sides of the bottom of the π-shaped beam, the spring loses its supporting force away from the π-shaped beam. The spring then drives the connecting plate to move towards the π-shaped beam, and the horizontal bar and the limiting rod, via the transmission of the connecting plate, also move back towards the π-shaped beam within the vertical plate. The device moves back to its initial position, and the rotating wheel, driven by the vertical plate, moves towards the π-shaped beam, returning to its initial position. This causes the bottom of the limiting rod to contact the top of the side extension plate of the π-shaped beam, thus fixing the side extension plate of the π-shaped beam vertically and preventing the π-shaped beam from tilting or swaying during use. Then, the U-shaped hanger is fixed by the lifting device, and the lifting device is moved by controlling it, so that the U-shaped hanger moves along with the lifting device, carrying the π-shaped beam to the usage position. This not only makes it easier for workers to lift and transport the π-shaped beam to the usage position, but also improves the stability of the device when moving the π-shaped beam.
[0007] Preferably, the end of the U-shaped hanger is fixedly connected to a lifting lug. By fixing the end of the U-shaped hanger to the lifting lug, workers can easily use lifting equipment to fix the U-shaped hanger, and move the U-shaped hanger by controlling the movement of the lifting equipment, so that the U-shaped hanger can be lifted and moved along with the π-shaped beam driven by the lifting equipment.
[0008] Preferably, the roller is aligned with the crossbar in the left-right direction. By aligning the roller with the crossbar in the left-right direction, the stability of the crossbar when it moves away from the π-shaped beam within the vertical plate can be improved.
[0009] Preferably, two limiting rods are provided on the connecting plate, with the two limiting rods located on the front and rear sides of the crossbar, respectively. By providing two limiting rods on the connecting plate, with the two limiting rods located on the front and rear sides of the crossbar, the stability of the device when moving the π-shaped beam can be improved.
[0010] Preferably, the front and rear side walls of the rotating wheel are respectively fitted into the front and rear upright plates. By fitting the front and rear side walls of the rotating wheel into the front and rear upright plates, the stability of the rotating wheel during use can be improved.
[0011] Preferably, the vertical plate and the U-shaped hanging body are configured as an integrated structure. By configuring the vertical plate and the U-shaped hanging body as an integrated structure, the stability between the vertical plate and the U-shaped hanging body during use can be improved.
[0012] Preferably, the inner wall of the side rod of the U-shaped hanger is aligned with the vertical axis of the rotating wheel. By aligning the inner wall of the side rod of the U-shaped hanger with the vertical axis of the rotating wheel, it is easier for the π-shaped beam to enter the U-shaped hanger, and the side extension plates on the left and right sides of the bottom of the π-shaped beam contact the side wall of the rotating wheel inside the U-shaped hanger that is away from the crossbar.
[0013] The beneficial effects of this utility model are as follows: By setting a U-shaped hanging body, vertical plates are fixed to the left and right side walls of the U-shaped hanging body. Two horizontal bars are set on the inner side walls of the vertical plates. The two horizontal bars are located on the front and rear sides of the U-shaped hanging body, respectively. The horizontal bars extend laterally in the left and right direction and pass through the vertical plates. Two vertical plates are fixed to the inner side walls of the horizontal bars and distributed laterally in the front and rear direction. A rotating wheel is set inside the U-shaped hanging body and rotatably connected to the front and rear vertical plates. A connecting plate is fixed to the outer side wall of the horizontal bars. A spring is sleeved on the horizontal bars and fixed to the connecting plate and the vertical plates. A limiting rod is fixed to the inner side wall of the connecting plate. The end of the limiting rod away from the connecting plate extends laterally in the left and right direction, passes through the vertical plate, and connects with the rotating wheel. The inner walls are aligned, the bottom of the limiting rod is aligned with the bottom of the rotating wheel, and the top of the limiting rod is aligned with the horizontal axis of the rotating wheel. In use, a U-shaped hanger is placed every 0.5 meters on the π-shaped beam, and the U-shaped hangers are controlled to move upwards, causing the π-shaped beam to enter the U-shaped hanger. This causes the side extension plates on the left and right sides of the bottom of the π-shaped beam to contact the side wall of the rotating wheel inside the U-shaped hanger, away from the crossbar. Driven by the side extension plates on the left and right sides of the bottom of the π-shaped beam, the rotating wheel rotates downwards, and the crossbar, driven by the vertical plate and the rotating wheel, and pushed by the side extension plates on the left and right sides of the bottom of the π-shaped beam, moves within the vertical plate in a direction away from the π-shaped beam. The connecting plate moves away from the π-shaped beam along with the vertical plate, stretching the spring. The limiting rod also moves away from the π-shaped beam within the vertical plate along with the connecting plate. This causes the side extension plates on the left and right sides of the bottom of the π-shaped beam to move below the limiting rod via the rotating wheel and the limiting rod, contacting the inner wall of the U-shaped hanging rod. At this point, because the rotating wheel and the limiting rod are no longer in contact with the side extension plates on the left and right sides of the bottom of the π-shaped beam, the spring loses its supporting force away from the π-shaped beam. The spring then drives the connecting plate to move towards the π-shaped beam, and the horizontal bar and the limiting rod, via the transmission of the connecting plate, also move back towards the π-shaped beam within the vertical plate. The device moves back to its initial position, and the rotating wheel, driven by the vertical plate, moves towards the π-shaped beam, returning to its initial position. This causes the bottom of the limiting rod to contact the top of the side extension plate of the π-shaped beam, thus fixing the side extension plate of the π-shaped beam vertically and preventing the π-shaped beam from tilting or swaying during use. Then, the U-shaped hanger is fixed by the lifting device, and the lifting device is moved by controlling it, so that the U-shaped hanger moves along with the lifting device, carrying the π-shaped beam to the usage position. This not only makes it easier for workers to lift and transport the π-shaped beam to the usage position, but also improves the stability of the device when moving the π-shaped beam.

[0019] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0020] like Figures 1-3 The present invention discloses a hoisting support for a π-shaped beam, comprising a U-shaped hanging body 4. Vertical plates 7 are fixed to the left and right side walls of the U-shaped hanging body 4. Two horizontal bars 5 are provided on the inner side walls of the vertical plates 7, located on the front and rear sides of the U-shaped hanging body 4 respectively. The horizontal bars 5 extend laterally in the left-right direction and pass through the vertical plates 7. Two vertical plates 8 are fixed to the inner side walls of the horizontal bars 5, distributed laterally in the front-rear direction. A rotating wheel 2 is provided inside the U-shaped hanging body 4, rotatably connected to the front and rear vertical plates 8. The horizontal bars 5... A connecting plate 3 is fixedly connected to the outer side wall. A spring 9 is sleeved on the crossbar 5 and fixedly connected to the connecting plate 3 and the vertical plate 7. A limiting rod 6 is fixedly connected to the inner side wall of the connecting plate 3. The end of the limiting rod 6 away from the connecting plate 3 extends laterally in the left-right direction, passes through the vertical plate 7 and is flush with the inner side wall of the rotating wheel 2. The bottom of the limiting rod 6 is flush with the bottom of the rotating wheel 2. The top of the limiting rod 6 is flush with the horizontal axis of the rotating wheel 2. The vertical distance between the limiting rod 6 and the inner side wall of the top rod of the U-shaped hanging body 4 is consistent with the vertical height of the side extension plate of the π-shaped beam.
[0021] By fixing lifting lugs 1 to the ends of the U-shaped hanging body 4, workers can easily use lifting equipment to lift the U-shaped hanging body 4 and the π-shaped beam located within it. Aligning the rotating wheel 2 with the horizontal bar 5 in the left-right direction improves the stability of the horizontal bar 5 when moving away from the π-shaped beam within the vertical plate 7. Having two limiting rods 6 on the connecting plate 3, located on the front and rear sides of the horizontal bar 5 respectively, enhances the stability of the device when moving the π-shaped beam. The front and rear side walls of the rotating wheel 2 are fitted against the front and rear vertical plates 8, respectively, improving the stability of the rotating wheel 2 during use. By making the vertical plate 7 and the U-shaped hanging body 4 an integrated structure, the stability between the vertical plate 7 and the U-shaped hanging body 4 during use is improved. By aligning the inner wall of the side bar of the U-shaped hanger 4 with the vertical axis of the wheel 2, it is possible to facilitate the entry of the π-shaped beam into the U-shaped hanger 4, and to make the side extension plates on the left and right sides of the bottom of the π-shaped beam contact the side wall of the wheel 2 on the inner side of the U-shaped hanger 4 away from the crossbar 5.
[0022] Combined with appendix Figure 1-3The method of using this utility model is as follows: First, a U-shaped hanging body 4 is placed every 0.5 meters on the π-shaped beam, and the U-shaped hanging body 4 is controlled to move upward, so that the π-shaped beam enters the U-shaped hanging body 4. This causes the side extension plates on the left and right sides of the bottom of the π-shaped beam to contact the side wall of the rotating wheel 2 on the inner side of the U-shaped hanging body 4 away from the crossbar 5. This causes the rotating wheel 2 to rotate downward under the drive of the side extension plates on the left and right sides of the bottom of the π-shaped beam. The crossbar 5, under the transmission of the vertical plate 8 and the rotating wheel 2, and pushed by the side extension plates on the left and right sides of the bottom of the π-shaped beam, moves in the vertical plate 7 away from the π-shaped beam. The connecting plate 3 also moves in the direction away from the π-shaped beam along with the vertical plate 7, thereby stretching the spring 9. The limiting rod 6 also moves in the direction away from the π-shaped beam along with the connecting plate 3 in the vertical plate 7. This causes the side extension plates on the left and right sides of the bottom of the π-shaped beam to move to the position below the limiting rod 6 via the rotating wheel 2 and the limiting rod 6, and then... When the inner wall of the top rod of the U-shaped hanger 4 contacts the bottom, the roller 2 and the limiting rod 6 no longer contact the left and right side extension plates at the bottom of the π-shaped beam. The spring 9 loses its supporting force in the direction away from the π-shaped beam. The spring 9 will drive the connecting plate 3 to move towards the π-shaped beam, and the horizontal bar 5 and the limiting rod 6 will also move towards the π-shaped beam in the vertical plate 7 through the transmission of the connecting plate 3, returning to their initial positions. The roller 2 will also move towards the π-shaped beam in the vertical plate 8 through the transmission of the vertical plate, thus making the bottom of the limiting rod 6 contact the top of the side extension plate of the π-shaped beam, thereby fixing the side extension plate of the π-shaped beam in the vertical direction and preventing the π-shaped beam from tilting or swaying during use. Then, by fixing the lifting device and the lifting lug 1, the lifting device is fixed to the U-shaped hanger 4. By controlling the movement of the lifting device, the U-shaped hanger 4 is lifted and moved along with the lifting device to transport the π-shaped beam to the use position.
