Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, and in particular to a segmental beam suspension system with self-balancing variable lifting points. Background Technology

[0002] Bridge segmental beam hoisting typically employs sling hoisting. Due to construction constraints, segmental beams vary in weight, structure, construction techniques, and mechanical properties. During construction, a single bridge segmental beam often requires multiple hoisting points, necessitating various hoisting systems for each segment. This not only presents inconvenience and reduces construction efficiency but also increases construction costs.

[0003] Therefore, it is necessary to provide a segmental beam suspension system with self-balancing variable lifting points to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a segmental beam suspension system with self-balancing variable lifting points. This system can longitudinally adjust the position of the equalizing beam on the support according to the lifting point position of the segmental beam, thereby meeting the suspension requirements of different segmental beams and greatly enhancing the versatility of the self-balancing variable lifting point segmental beam suspension system.

[0005] To achieve the above objectives, the technical solution proposed in this utility model is as follows: a segmental beam suspension system with self-balancing variable lifting points, comprising:

[0006] The system includes a main beam, a balance beam, and a sliding connecting seat. The main beam comprises a main body and a support connected to the main body. The support is equipped with a limiting component.

[0007] The equalizing beam has elongated holes at both ends. The sliding connecting seat is hinged to the bottom of the equalizing beam. The equalizing beam is slidably connected to the support through the sliding connecting seat. The limiting component passes through the equalizing beam and the sliding connecting seat to limit the movement distance of the equalizing beam on the support.

[0008] Preferably, the limiting component includes a fixed bracket, a threaded rod, and a fixing member. The fixed bracket is fixedly installed on the support, the threaded rod passes through the fixed bracket, the sliding connecting seat, and the equalizing beam, and the fixing member is detachably installed on the threaded rod.

[0009] Preferably, the edge of the support extends to form a flange, the sliding connection seat includes a seat body and a rotating shaft, the seat body bends downward to form a barb, the rotating shaft passes through the seat body and the equalizing beam, the equalizing beam is hinged and installed, the seat body is slidably installed on the support, and the barb hooks the flange.

[0010] Preferably, the equalizing beam has elongated holes.

[0011] Preferably, the main beam is provided with lifting lugs.

[0012] Compared with existing technologies, the advantages are: 1) The position of the equalization beam on the support can be adjusted longitudinally according to the position of the suspension point of the segmental beam to meet the suspension requirements of different segmental beams;

[0013] 2) Furthermore, because the equalizing beam and the sliding connection seat are installed using a hinged method, the two ends of the equalizing beam can swing up and down, which can automatically balance the load at both ends of the equalizing beam, ensuring that the equalizing beam is evenly stressed, and thus ensuring that the segmental beam suspension points are evenly stressed. In this way, the versatility of the segmental beam suspension with self-balancing variable suspension points is greatly enhanced.

[0023] Please see Figures 1 to 2 This utility model proposes a segmental beam suspension system with self-balancing variable lifting points, comprising:

[0024] The system includes a main beam 1, a balance beam 2, and a sliding connecting seat 3. The main beam 1 includes a main body 11 and a support 12 connected to the main body 11. The support 12 is provided with a limiting component 13.

[0025] The equalizing beam 2 has elongated holes 21 at both ends. The sliding connecting seat 3 is hinged to the bottom of the equalizing beam 2. The equalizing beam 2 is slidably connected to the support 12 through the sliding connecting seat 3. The limiting component 13 passes through the equalizing beam 2 and the sliding connecting seat 3 to limit the movement distance of the equalizing beam 2 on the support 12.

[0026] It should be noted that in this embodiment, the main beam 1 is in the shape of an "I", and there are two branches 12, which are vertically connected to the two ends of the main body 11; there are four equalizing beams 2, which are divided into two groups (each group has two equalizing beams 2), one group of equalizing beams 2 is installed on one branch 12, and the other group of equalizing beams 2 is installed on another branch 12.

[0027] The elongated hole 21 on the equalization beam 2 is to facilitate the lateral change of the lifting point position, reserve the lifting position for the segment beam in the lateral direction, and make it convenient to flexibly adjust the lifting point position according to the construction conditions.

[0028] When facing different segmental beams during construction, the lifting point positions of different segmental beams will be different from those of the previous segmental beams. Since the equalizing beam 2 is installed by sliding on the support 12, the spacing of the four equalizing beams 2 on the support 12 can be adjusted longitudinally according to the lifting point position of the segmental beam to meet the hanging requirements of different segmental beams.

[0029] Furthermore, since the equalizing beam 2 and the sliding connecting seat 3 are installed using a hinged connection, the two ends of the equalizing beam 2 can swing up and down, automatically balancing the load at both ends of the equalizing beam 2 and ensuring uniform force distribution on the equalizing beam 2, thereby ensuring uniform force distribution at the segmental beam lifting points. This greatly enhances the versatility of the self-balancing variable lifting point segmental beam suspension system.

[0030] In a preferred embodiment, the main beam 1 is provided with lifting lugs 10, which facilitates the crane's wire rope to pass through the lifting lugs 10 to lift the segmental beam with a self-balancing variable lifting point.

[0031] In a preferred embodiment, the limiting component 13 includes a fixed bracket 131, a threaded rod 132, and a fixing member 133. The fixed bracket 131 is fixedly installed on the support 12, the threaded rod 132 passes through the fixed bracket 131, the sliding connecting seat 3, and the equalizing beam 2, and the fixing member 133 is detachably installed on the threaded rod 132.

[0032] It should be noted that in this embodiment, the number of limiting components 13 is four; the fixing member 133 can be a nut, and the number of fixing members 133 can be three, of which two fixing members 133 are distributed on both sides of the sliding connecting seat 3, and the remaining fixing member 133 is distributed on the side of the fixed bracket 131 away from the sliding connecting seat 3. By turning and adjusting the position of the three fixing members 133 on the screw, the equalizing beam 2 can be restricted longitudinally to different positions of the support 12.

[0033] In a preferred embodiment, the edge of the support 12 extends to form a flange 121. The sliding connecting seat 3 includes a seat body 31 and a rotating shaft 32. The seat body 31 bends downward to form a barb 311. The rotating shaft 32 passes through the seat body 31 and the equalizing beam 2, hingedly mounting the equalizing beam 2. The seat body 31 is slidably mounted on the support 12, and the barb hooks onto the flange 121. The advantage of this design is that when the seat body 31 slides on the support 12, the barb 311 on the seat body 31 can prevent the seat body 31 from becoming detached from the support 12, facilitating the horizontal movement of the seat body 31 along the support 12.

[0034] When facing different segmental beams during construction, the lifting point positions of different segmental beams will be different from those of the previous segmental beams. Since the equalizing beam 2 is installed by sliding on the support 12, the spacing of the four equalizing beams 2 on the support 12 can be adjusted longitudinally according to the lifting point position of the segmental beam to meet the hanging requirements of different segmental beams.

[0035] Furthermore, since the equalizing beam 2 and the sliding connecting seat 3 are installed using a hinged connection, the two ends of the equalizing beam 2 can swing up and down, automatically balancing the load at both ends of the equalizing beam 2 and ensuring uniform force distribution on the equalizing beam 2, thereby ensuring uniform force distribution at the segmental beam lifting points. This greatly enhances the versatility of the self-balancing variable lifting point segmental beam suspension system.

[0036] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
