Description

Technical Field

[0001] The utility model belongs to the field of building construction, and in particular relates to a steel pipe beam hoisting device. Background Art

[0002] A steel tubular beam is a structural member characterized by the use of steel tubes as the primary material. The construction and dimensions of a steel tubular beam can vary depending on design and engineering requirements. Steel tubular beams are primarily composed of steel tubes, which can be seamless or seamed, depending on engineering requirements and material specifications. Steel tubular beams can be round or square, depending on design and engineering requirements. The dimensions of a steel tubular beam include the diameter or width and thickness of the tubes, which are adjusted based on design and engineering needs. Steel tubular beams can be connected by welding, bolting, or other appropriate connection methods to ensure the stability and safety of the structure. Steel tubular beams are widely used in structures such as buildings, bridges, and tunnels to bear and transfer loads, ensuring the overall stability and safety of the structure.

[0003] When installing steel tube beams, it is usually necessary to hoist the steel tube beams to a required higher installation position, such as when building a bridge, a high-rise building, or the top of a tunnel. General steel tube beam hoisting devices usually use steel plate vertical clamps to fix the steel tube beams. However, during the hoisting construction, it is often necessary to hoist pipes of different lengths and specifications, and general hoisting devices cannot adjust the position of the steel plate vertical clamps, or adjusting the position of the steel plate vertical clamps is more troublesome.

[0004] Based on this, the applicant considered designing a steel tube beam lifting device. Utility Model Content

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] When implementing: Figure 1-4As shown, a steel tube beam lifting device includes a base 100, a limiting mechanism and a moving mechanism. The base 100 includes a bearing platform 110. The bearing platform 110 is used to place the steel tube beam. The limiting mechanism is installed on both sides of the bearing platform 110 and is used to limit the steel tube beam on both sides of the bearing platform 110. The moving mechanism is installed on the bearing platform 110 and is transmission-connected to the limiting mechanism, and is used to drive the limiting mechanism to slide along the length direction of the bearing platform 110.

[0023] Compared with the prior art, the advantages of the steel tube beam lifting device of the utility model are:

[0024] By setting up the base 100, the limiting mechanism and the moving mechanism, the limiting mechanism can move on the base 100 to adjust the relative position between the limiting mechanism and the base 100. At the same time, the moving mechanism can automatically drive the limiting mechanism to move on the base 100 to adjust the limiting position of the limiting mechanism on the steel pipe beam, and the adjustment is simple.

[0025] The above-mentioned steel tube beam lifting device has the advantages of simple structure and easy implementation. It is suitable for installation and use in the existing steel tube beam lifting process, and has low cost of use, which can improve efficiency.

[0026] In this embodiment, Figure 1-4 As shown, the base 100 also includes a slide 120 arranged on both sides of the load-bearing platform 110, and the sliding direction of the slide 120 is consistent with the length direction of the load-bearing platform 110. The limiting mechanism includes a first railing 210 and a second railing 220. The first railing 210 and the second railing 220 have the same structure and are respectively arranged on the two slides 120 opposite to each other. The first railing 210 and the second railing 220 both include a top end and a bottom end. The bottom ends of the first railing 210 and the second railing 220 are respectively slidably arranged on the two slides 120, and a first elastic positioning rod 211 is provided on the top end of the first railing 210, and a second elastic positioning rod 221 is provided on the top end of the second railing 220. The first elastic positioning rod 211 and the second elastic positioning rod 221 are arranged opposite to each other and can respectively abut against the steel pipe beam placed on the load-bearing platform 110 in two opposite directions.

[0027] In this way, by setting the slide 120, the first railing 210 and the second railing 220, the first railing 210 and the second railing 220 can limit the steel tube beam, so that the first railing 210 and the second railing 220 can move along the corresponding slide 120 to adjust the limiting position of the steel tube beam on the supporting platform 110. At the same time, the steel tube beam can be abutted and positioned by the first elastic positioning rod 211 and the second elastic positioning rod 221, and the limiting and positioning structures are relatively simple and reliable.

[0028] During implementation, two limiting mechanisms are provided on the slide 120 , and the two limiting mechanisms are arranged on the slide 120 along the length direction of the base 100 .

[0029] In this embodiment, Figure 1-4 As shown, the first elastic positioning rod 211 and the second elastic positioning rod 221 both include a fixed rod 230 and a telescopic rod 240. The two fixed rods 230 are respectively fixed to the top ends of the first railing 210 and the second railing 220. A telescopic cavity is provided in the fixed rod 230, and the telescopic cavity passes through one end face of the corresponding fixed rod 230. The openings of the telescopic cavities of the two fixed rods 230 are arranged opposite to each other, and the two telescopic rods 240 are respectively arranged in the two telescopic cavities and can telescope and slide along the corresponding telescopic cavities. A first compression spring 241 is provided between each telescopic rod 240 and the bottom surface of the corresponding telescopic cavity.

[0030] In this way, by setting the fixed rod 230 and the telescopic rod 240, the telescopic rod 240 can be retracted into the fixed rod 230 to allow the steel pipe beam to be placed in the supporting platform 110, and the telescopic rod 240 can also position the steel pipe beam placed in the supporting platform 110, making it easy to place.

[0031] During operation, telescopic rod 240 includes opposing first and second ends. The first end slides within the corresponding telescopic cavity, while the second end extends forward to abut against the steel tube beam. The top surface of the second end is provided with an inclined sliding surface that slopes forward and downward. During insertion, the weight of the steel tube beam causes the bottom of the beam to contact the inclined sliding surface, allowing telescopic rod 240 to retract into the telescopic cavity.

[0032] In this embodiment, Figure 1-4 As shown, a clamping portion 250 is provided on the bottom end of each of the first railing 210 and the second railing 220 , and the two clamping portions 250 are respectively clamped on the edges of the two slides 120 .

[0033] In this way, the first railing 210 and the second railing 220 can be more stably arranged on the slide 120 through the provided clamping portion 250 .

[0034] In this embodiment, Figure 1-4 As shown, a hanging hole 260 is provided on the top end of each of the first railing 210 and the second railing 220 .

[0035] In this way, through the provided lifting hole 260 , a lifting rope or a lifting hook on a crane can lift the base 100 through the lifting hole 260 , and the lifting is more stable and reliable.

[0036] In this embodiment, Figure 1-4 As shown, the moving mechanism includes a first motor 310, a second motor 320, a first transmission block 330 and a second transmission block 340. The first motor 310 is arranged on the edge of the supporting platform 110 near the first railing 210, and the first transmission shaft is coaxially connected to the first transmission shaft on the rotating shaft of the first motor 310. The transmission direction of the first transmission shaft is consistent with the sliding direction of the corresponding slide 120. The first transmission block 330 is transmission-connected to the first transmission shaft, and the first transmission block 330 is fixed to the side wall of the first railing 210. The second motor 320 is arranged on the edge of the supporting platform 110 near the second railing 220. The second motor 320 is coaxially connected to the second transmission shaft on the rotating shaft, and the transmission direction of the second transmission shaft is consistent with the sliding direction of the corresponding slide 120. The second transmission block 340 is transmission-connected to the second transmission shaft, and the second transmission block 340 is fixed to the side wall of the second railing 220.

[0037] In this way, by setting the first motor 310, the second motor 320, the first transmission block 330 and the second transmission block 340, the first railing 210 and the second railing 220 can be transmitted by the first motor 310 and the second motor 320, so as to quickly adjust the positions of the first railing 210 and the second railing 220. The adjustment mechanism is simple, the cost is low, the operation is convenient and the reliability is high.

[0038] During implementation, two moving mechanisms are provided on the supporting platform 110, and the two moving mechanisms are arranged opposite to each other. Each moving mechanism corresponds to a transmission of a limiting mechanism. Bearing blocks are provided in the middle of the edges on both sides of the supporting platform 110. One end of the first transmission shaft is connected to the first motor 310 for transmission, and the other end is connected to the corresponding bearing for quick rotation. One end of the second transmission shaft is connected to the second motor 320 for transmission, and the other end is connected to the corresponding bearing for quick rotation.

[0039] In this embodiment, Figure 1-4 As shown, a support column 410 is provided at the bottom of the base 100 , and a buffer mechanism is provided on the support column 410 , and the buffer mechanism is used to apply buffering to the bearing platform 110 when the bearing platform 110 falls to the ground.

[0040] In this way, by setting the support column 410 and the buffer mechanism, the impact of the bottom surface on the base 100 can be reduced when the base 100 touches the ground, thereby better protecting the steel pipe beam supported by the base 100, reducing the contact pressure between the base 100 and the steel pipe beam, and reducing damage to the steel pipe beam.

[0041] During implementation, there are four support columns 410 , and the four support columns 410 are arranged in a rectangular array at the bottom of the base 100 .

[0042] In this embodiment, Figure 1-4 As shown, the buffer mechanism includes a movable support leg 420 and a second compression spring 430. The movable support leg 420 is provided with an elastic cavity opening upward. The movable support leg 420 is sleeved on the support column 410 through the elastic cavity. The second compression spring 430 is arranged in the elastic cavity. One end of the second compression spring 430 is connected to the bottom surface of the support column 410, and the other end is connected to the bottom surface of the elastic cavity.

[0043] In this way, by setting up the movable support leg 420 and the second compression spring 430, when the movable support leg 420 contacts the ground, the second compression spring 430 can reduce the impact force between the support column 410 and the ground, so as to reduce the impact force on the base 100, and the buffer structure is relatively simple and reliable.

[0044] In this embodiment, Figure 1-4 As shown, a bearing groove 500 is provided on the top surface of the bearing platform 110, and the bearing groove 500 is used to place the steel pipe beam.

[0045] In this way, by providing the bearing groove 500 , the steel tube beam can be initially positioned in the transverse direction after being placed on the bearing platform 110 . The positioning structure is simple and reliable, and the manufacturing cost is low.

[0046] In this embodiment, Figure 1-4 As shown, the cross section of the bearing groove 500 is arc-shaped.

[0047] In this way, by setting the bearing groove 500 to be an arc shape, the bearing groove 500 can better bear the circular steel tube beam, and the bearing structure is stable.

[0048] The above are only preferred implementations of the present invention. It should be pointed out that various modifications and improvements made by those skilled in the art without departing from the present technical solution should also be deemed to fall within the scope of protection required by the claims.
