Description

TECHNICAL FIELD

[0001] The utility model relates to building engineering large -scale steel structural member transportation technical field, concretely relates to a large -scale steel pipe arch truss transportation crossbeam device. BACKGROUND

[0002] Large -scale steel pipe arch trusses are widely used in large -scale building structures such as stadiums, museums, railway stations and stockyards because they can realize large span. However, the cross-sectional size of such structures is large, the weight is large, and the structure is arched with an arc, belonging to the category of over-limit transportation. The conventional method is to assemble near the site and then transport to the installation site in sections, which puts high requirements on transportation technology and safety guarantee.

[0003] In the actual transportation process, there are still the following challenges: the volume and weight of large -scale steel pipe arch truss sections are still huge, the transportation process has extremely harsh requirements on road conditions, vehicle performance and binding and fixing technology, and the safety risk is high; sectional transportation requires special sites for assembly and transfer, increasing the complexity and cost of the project; the safety of traditional transportation beams is poor, the turnover is poor, and the utilization rate is not high.

[0004] Therefore, it is urgent to develop a lightweight, high-strength, size-adjustable and efficient and reusable special transportation beam to effectively solve the problem of safe and efficient transportation of large -scale steel pipe arch trusses. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a large -scale steel pipe arch truss transportation crossbeam device to solve the problem of poor transportation stability, easy deformation and damage and insufficient adaptability to transport vehicles caused by large cross-sectional size, large weight and arch shape of large -scale steel pipe arch trusses.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a large -scale steel pipe arch truss transportation crossbeam device, comprising an axis line vehicle, an H-shaped steel crossbeam, a stiffened plate, a seat and a bolt; the H-shaped steel crossbeam is arranged on the axis line vehicle and is used for bearing large -scale steel pipe arch truss sections; the large -scale steel pipe arch truss section is welded by a truss top chord, a truss web, a truss top chord pipe and a truss bottom chord pipe;

[0007] Two sides of the web of the H-shaped steel crossbeam are welded with stiffened plates at positions corresponding to the truss top chord pipe and the truss bottom chord pipe and at positions corresponding to the concentrated force contact of both ends of the axis line vehicle, a total of four places, six pieces arranged on both sides, three pieces on each side.

[0008] The upper part of the H-shaped steel crossbeam is connected with the seat through the bolt at the position corresponding to the truss top chord pipe and the truss bottom chord pipe; the seat is used for supporting and fixing the truss top chord pipe and the truss bottom chord pipe;

[0009] Preferably, the stiffened plate is symmetrically welded on both sides of the web of the H-shaped steel beam.

[0010] By adopting the technical scheme, the stiffened plate significantly improves the local bending stiffness and stability of the H-shaped steel beam at the key stress points.

[0011] Preferably, the bracket is connected with the H-shaped steel beam through bolts.

[0012] By adopting the technical scheme, the bolt connection mode can adjust the position of the bracket according to the specific position of the chord pipe of the truss, ensure that the bracket is closely attached to the chord pipe, and enhance the transportation stability.

[0013] Preferably, the transportation beam device is provided with at least one in front of and one behind the sectional length direction of the steel pipe arch truss.

[0014] By adopting the technical scheme, the multiple-point support effectively disperses the load, and ensures the overall stability of the sectional steel pipe arch truss during transportation.

[0015] Compared with the prior art, the utility model has the advantages of:

[0016] The stability is high, and the protection component: through the design of the H-shaped steel beam combined with the stiffened plate and the adjustable bracket, the large steel pipe arch truss is effectively prevented from slipping, colliding and deforming during transportation, and the transportation is ensured to be firm and stable.

[0017] The load is uniformly transmitted: the optimized structural design (stiffened plate and multiple-point support) more uniformly transmits the concentrated load of the large steel pipe arch truss to the axle line vehicle, reduces the local stress, and improves the transportation safety.

[0018] The adaptability is high: the bracket is connected with the beam through bolts, the position is adjustable, the chord pipe of the truss can be adapted to different pipe diameters and cambers, the close attachment is ensured, and the stability is enhanced.

[0019] The device is solid and reliable, can be disassembled, can be repeatedly used for the transportation task of different large steel pipe arch truss sections, and reduces the engineering cost.

[0020] The structure is simple, and the installation is convenient: the main components (H-shaped steel beam, stiffened plate and bracket) are relatively simple to process and manufacture, the stiffened plate is welded, the bracket is connected through bolts, and the device is hoisted to the axle line vehicle, so that the on-site installation is convenient and fast, and the construction efficiency is improved.
