Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bridge transportation equipment, and in particular to a beam conveying device for assisting in building a beam body and a construction method thereof. Background Art
[0002] Many cross-sea bridges and viaducts require the beams to be slowly moved by bridge transportation equipment so that the bridges can be moved between the piers and supported by the piers. In the prior art, it is necessary to set up a support platform for intermediate connection, that is, to temporarily receive the beams. However, since the center of gravity of the beam will also move forward relative to the support platform during the forward movement, the steel pipe columns at various positions of the support platform must meet the strength requirements. That is to say, although the support platform has multiple steel pipe columns that act as foot supports, the center of gravity of the beam will gradually move, resulting in different pressures on each steel pipe column, and therefore each steel pipe column is required to have greater strength to prevent the support platform from being crushed by the beam. Summary of the invention
[0003] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a beam delivery device for assisting in building a beam body, which reduces the strength requirement of a support platform while meeting the load-bearing requirement of the beam body.

[0013] Furthermore, a plurality of the first supporting columns are distributed at intervals along the length direction and the width direction of the sliding beam.
[0014] Furthermore, the top of the sliding beam is supported by a plurality of first pads, and the sliding beam supports the beam body to be moved through the first pads.
[0015] Furthermore, a second cushion block is connected to the top of the second supporting column, and the beam to be moved is supported by the second cushion block.
[0016] Furthermore, there are multiple second supporting columns, the extension direction of the multiple second supporting columns is parallel to the horizontal plane, and the multiple second supporting columns are arranged at intervals along the horizontal direction; the support platform supports a second distribution beam, and the second distribution beam is located directly below the multiple second supporting columns and supports the multiple second supporting columns.
[0017] Furthermore, the support platform is provided with a reinforcement structure, and the reinforcement structure is located directly below the three-way jack and the second distribution beam.
[0018] Furthermore, the reinforcement structure is a diagonal brace, and the bottom end of the diagonal brace is connected to the supporting foot.
[0019] Furthermore, there are multiple three-way jacks, and the first distribution beam is supported by multiple three-way jacks.
[0020] The second object of the present invention is achieved by adopting the following technical solution:

[0024] Step c: the three-way jack drives the sliding beam to descend, so that the beam to be moved is supported by the second supporting column; the three-way jack continues to drive the sliding beam to descend, so that the sliding beam is supported by the first supporting column; the output part of the three-way jack continues to descend and is separated from the support of the sliding beam, and then the output part of the three-way jack is horizontally contracted;

The terms used in the specification of the invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0041] Figure 1-Figure 5 A beam conveying device for assisting in the construction of a beam body according to a preferred embodiment of the present invention is shown, comprising a support platform 1, a three-way jack 2, a sliding beam 3, a plurality of first supporting columns 5, and a second supporting column 6 (in the present embodiment, a plurality of second supporting columns 6 are also preferably provided).
[0042] The support platform 1 includes a support table 11 and a plurality of support legs 12 connected to the bottom of the support table 11. Obviously, the support legs 12 play the role of supporting the support table 11 and are indispensable. Figure 2-Figure 5As the beam 4 to be moved moves to the right, its center of gravity will gradually move to the right, so that the strength of the support feet 12 at various positions of the support platform 1 must be designed with the highest strength to avoid a certain support foot 12 from being crushed.
[0043] The three-way jack 2 is arranged on the support platform 11 and supported by the support platform 11. According to the function of the mature three-way jack 2, its output part can not only move horizontally, but also move up and down, so as to link the sliding beam 3 to move horizontally and move up and down.
[0044] The sliding beam 3 is located directly above the three-way jack 2. When the output portion of the three-way jack 2 rises, the sliding beam 3 can be lifted and driven. The sliding beam 3 is used to lift the beam body 4 to be moved and link the beam body 4 to be moved.
[0045] The plurality of first supporting columns 5 are supported by the supporting platform 11 and are located directly below the sliding beam 3 , and are used to temporarily support the sliding beam 3 so that the output portion of the three-way jack 2 can be separated from the sliding beam 3 .
[0046] The second supporting column 6 is supported by the supporting platform 11 and is used to temporarily support the beam body 4 to be moved, so that the sliding beam 3 and the beam body 4 to be moved can be separated from each other.
[0047] In the traditional jacking technology for the beam body 4 (steel truss) to be moved, the fulcrum of the beam body 4 to be moved is constantly moving on the support platform 1, and all parts of the support platform 1 need to be designed with the maximum load. The present invention optimizes the force characteristics of the support platform 1, specifically by supporting the sliding beam 3 through a plurality of first supporting columns 5, and supporting and linking the beam body 4 to be moved through the sliding beam 3, so that the beam body 4 to be moved is weighed by the support platform 1 as a whole, and the beam body 4 to be moved is supported by the part of the support platform 1 located at the position of the three-way jack 2 (thereby the strength of the part can be strengthened in a targeted manner, and there is no need to design all parts of the support platform 1 with the maximum load); therefore, the problem of insufficient strength in the traditional jacking technology for the beam body 4 (steel truss) to be moved is overcome, and the material consumption of the steel and foundation of the support platform 1 is reduced, thereby reducing the cost.
[0048] Preferably, see Figure 1 The beam delivery device for assisting in building the beam body also includes a first distribution beam 7, which is supported by the three-way jack 2 and is drivingly connected to the three-way jack 2. The first distribution beam 7 is located directly below the sliding beam 3. By adding the first distribution beam 7, multiple three-way jacks 2 can synchronously support the first distribution beam 7, so that the lifting process of the sliding beam 3 is more stable.
[0049] Preferably, see Figure 1The plurality of first supporting columns 5 are distributed at intervals along the length direction and the width direction of the sliding beam 3 to more evenly distribute the weight of the beam body 4 to be moved, thereby further reducing the strength requirement of a single supporting leg 12 .
[0050] Preferably, see Figure 1 The top of the sliding beam 3 supports a plurality of first pads 8, and the sliding beam 3 supports the beam body 4 to be moved through the first pads 8. In this way, the first pads 8 can buffer the rigid contact force between the sliding beam 3 and the beam body 4 to be moved to avoid damage to the beam body. Preferably, similarly, the top of the second supporting column 6 is connected to a second pad 9, and the beam body 4 to be moved is supported through the second pad 9.
[0051] Preferably, see Figure 1 , there are multiple second supporting columns 6, the extension direction of the multiple second supporting columns 6 is parallel to the horizontal plane, and the multiple second supporting columns 6 are arranged at intervals along the horizontal direction; the support platform 11 supports the second distribution beam 10, and the second distribution beam 10 is located directly below the multiple second supporting columns 6 and supports the multiple second supporting columns 6. In this way, each second supporting column 6 can be supported by the second distribution beam 10 at the same time, and the distribution beam is supported by the support platform 11, so that the support platform 11 can be uniformly squeezed by the second distribution beam 10 to avoid the phenomenon of insufficient local strength. In this way, it is only necessary to strengthen the support platform 11 locally to support the second distribution beam 10.
[0052] Preferably, see Figure 1 The support platform 1 is provided with a reinforcement structure 13, which is located directly below the three-way jack 2 and the second distribution beam 10. Preferably, the reinforcement structure 13 is a diagonal brace, and the bottom end of the diagonal brace is connected to the support foot 12. It can be understood that as an alternative to the diagonal brace, the local thickness of the support platform 1 can be directly strengthened, or the local material can be changed to improve its strength.
[0053] Preferably, a plurality of three-way jacks 2 are provided, and the first distribution beam 7 is supported by a plurality of three-way jacks 2. This arrangement enables the beam conveying device for assisting in the construction of the beam body to convey heavier steel trusses.
[0054] The present invention also discloses a construction method of a beam delivery device for assisting in building a beam body, comprising the beam delivery device for assisting in building a beam body and the following steps:
[0055] Step a: The three-way jack 2 lifts the sliding beam 3, and enables the sliding beam 3 to lift the beam body 4 to be moved.
[0056] Step b (see Figure 3): Extend through the output part of the three-way jack 2 to drive the sliding beam 3 to move horizontally, and link the beam body 4 to be moved along the target direction.
[0057] Step c: the three-way jack 2 drives the sliding beam 3 to descend, so that the beam body 4 to be moved is supported by the second supporting column 6 (second cushion block 9); the three-way jack 2 continues to drive the sliding beam 3 to descend, so that the sliding beam 3 is supported by the first supporting column 5 (first cushion block 8); the output part of the three-way jack 2 continues to descend and is separated from the support for the sliding beam 3, and then the output part of the three-way jack 2 contracts horizontally.
[0058] Step d: See Figure 4 , repeat step a, step b and step c in sequence until the tail end of the sliding beam 3 is close to the three-way jack 2.
[0059] Step e: The three-way jack 2 drives the sliding beam 3 to descend so that the beam body 4 to be moved is supported by the second supporting column 6, and after the sliding beam 3 is separated from the beam body 4 to be moved, the output part of the three-way jack 2 contracts horizontally to drive the sliding beam 3 to retreat relative to the beam body 4 to be moved.
[0060] Step f: The output part of the three-way jack 2 descends so that the sliding beam 3 is supported by the first supporting column 5, and then the output part of the three-way jack 2 extends, and then the output part of the three-way jack 2 rises and lifts the sliding beam 3, and then the output part of the three-way jack 2 continues to contract horizontally to drive the sliding beam 3 to continue to retreat relative to the beam body 4 to be moved.
[0061] Step g: See Figure 5 , repeat step e and step f until the sliding beam 3 returns to its initial position (ie, until the front end of the sliding beam 3 is close to the three-way jack 2).
[0062] Step h: Repeat steps a to g until the beam 4 to be moved is moved to the target position.
[0063] Obviously, the construction method of the beam delivery device for assisting in the construction of the beam body repeatedly delivers the beam body 4 to be moved by the sliding beam 3 in a progressive manner, thereby finally delivering the beam body 4 to be moved to the target position. This delivery process solves the problem that each part of the support platform 1 needs to be designed with the maximum load.
[0064] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
