[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a prestressed box girder storage device, comprising at least two supporting components, a plurality of soft protective components are arranged at intervals on the upper side of the supporting components, grooves with the same number as the soft protective components are opened on the supporting components, a telescopic mechanism is vertically arranged in the groove, and a roller is arranged at the upper end of the telescopic mechanism.

[0005] Preferably, the supporting component is made of a rectangular parallelepiped steel product.

[0006] Preferably, the soft protective component includes tires, and chains are inserted between multiple groups of the tires, and both ends of the chain are connected with annular bolts installed on the supporting component.

[0007] Preferably, the groove is arranged below the tire and coaxially therewith, and the diameter of the groove is smaller than the diameter of the inner ring of the tire.

[0008] Preferably, at least one set of fixing rings are provided on both the left and right sides of the supporting component, and the box beam is reinforced by a nylon rope between every two opposite fixing rings.

[0009] Preferably, the telescopic mechanism includes a vertically arranged electric telescopic rod support component on which a spirit level is provided.

[0010] The utility model provides a prestressed box beam storage device, which has the following beneficial effects:

[0011] The prestressed box girder storage device can protect the box girder after it is placed on the tires, preventing wear on the lower side of the box girder as much as possible, and can limit the tires through the cooperation of ring bolts and chains to prevent the tires from moving. With the cooperation of the telescopic mechanism and the rollers, when one side of the box girder is under excessive pressure, the telescopic mechanism drives the roller pair to support the box girder, ensuring that the force on the box girder is uniform and stable as much as possible.

[0016] The present invention will be further described below in conjunction with specific embodiments. Figures 1 to 3 As shown:

[0017] Embodiment 1: A prestressed box girder storage device comprises at least two support components 1, the support components 1 are arranged at intervals, and the two support components 1 provide support for both ends of the box girder respectively;

[0018] A plurality of soft protective components are arranged at intervals on the upper side of the support component 1. The arrangement of the soft protective components can reduce the wear of the bottom thereof and provide protection for the box girder as much as possible;

[0019] The supporting component 1 is provided with grooves 2 whose number is the same as that of the soft protective components, a telescopic mechanism is vertically provided in the groove 2, and a roller 3 is provided at the upper end of the telescopic mechanism. When the box beam tilts to one side of the supporting component 1, the telescopic mechanism can drive the roller 3 to provide support for the box beam, so as to avoid excessive force on one side of the box beam as much as possible.

[0020] Embodiment 2: A prestressed box girder storage device comprises at least two support components 1, wherein the support components 1 are made of rectangular parallelepiped steel products to ensure that their load-bearing capacity meets the standards, the support components 1 are arranged at intervals, and the two support components 1 provide support for both ends of the box girder respectively;

[0021] A plurality of soft protective components are arranged at intervals on the upper side of the support component 1. The soft protective components include tires 4. Chains 5 are inserted between the plurality of tires 4. Both ends of the chains 5 are connected with annular bolts 6 installed on the support component 1. With the cooperation of the chains 5 and the annular bolts 6, the stability of the tires 4 can be ensured, thereby avoiding the tires 4 from moving as much as possible. By setting the soft protective components, the wear on the bottom can be reduced, and the box beam can be protected as much as possible.

[0022] The supporting component 1 is provided with grooves 2 having the same number as the soft protective component. The grooves 2 are arranged below the tire 4 and are coaxially arranged therewith. The diameter of the grooves 2 is smaller than the diameter of the inner ring of the tire 4. A telescopic mechanism is vertically arranged in the groove 2. A roller 3 is arranged at the upper end of the telescopic mechanism. The telescopic mechanism includes a vertically arranged electric telescopic rod 9, which is powered by an external power supply. When the box beam tilts to one side of the supporting component 1, the telescopic mechanism can drive the roller 3 to provide support for the box beam, so as to avoid excessive force on one side of the box beam as much as possible.

[0023] At least one set of fixing rings 7 is provided on both sides of the support member 1. When in use, the box beam is fixed by a nylon rope between every two opposite fixing rings 7 to prevent it from shaking.

[0024] After the box beam is placed on the supporting member 1, the box beam can be simply fixed by the nylon rope 8 and the fixing ring 7, and the material of the nylon rope will not cause wear to the box beam;

[0025] A level 10 is provided on the supporting component 1 to prevent the box beam from tipping over as much as possible.

[0026] Working principle:

[0027] By setting the spirit level 10, after the support component 1 is placed in the box beam storage area, it is possible to observe whether the support component 1 is in a horizontal state, so as to facilitate timely adjustment. Then, the box beam tube lifting equipment is lifted onto the support component 1. By setting the tire 4, after the new box beam is placed on the support component 1, the bottom of the box beam can be protected to avoid damage as much as possible. With the cooperation of the telescopic mechanism and the roller 3, when one side of the box beam is tilted, the telescopic mechanism can drive the roller 3 to provide support for the box beam, and support the box beam in a horizontal position as much as possible to make it evenly stressed, thereby preventing the uneven stress on the box beam from causing damage to one side. At the same time, when the box beam is not in place, it is convenient to adjust the position of the box beam. By setting the fixing ring 7 and the nylon rope 8, the box beam can be reinforced to prevent the box beam from shaking.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
