[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a prefabricated T-beam transport anti-overturning device of the utility model comprises support rods 2, and the fixed ends of each pair of support rods 2 are relatively hinged on the beam transport vehicle plate 4, and the support rods 2 are telescopic rods. The telescopic rods can be telescopically fixed by sleeve pins or screw rods. The support rods 2 are one pair or multiple pairs, and the multiple pairs are at least two pairs, such as each pair of support rods 2 is hinged on the beam transport vehicle plate 4 relative to the length direction of the beam transport vehicle plate 4. The support rods 2 are rotated on the beam transport vehicle plate 4 by pins or loose-leaf structures.

[0026] A prefabricated T-beam transportation anti-overturning device based on the above structure, wherein the support rod 2 is a telescopic rod, so the length of the support rod 2 can be adjusted according to the height of the prefabricated T-beam 9, which is convenient for adjusting and reinforcing prefabricated T-beams 9 of different models and heights during transportation, and coordinating with the height of prefabricated T-beams 9 of different heights to improve the quality of the prefabricated T-beam transportation anti-overturning support; the support method is flexible and easy to operate. Without replacing the support rod 2, the length of the support rod 2 can be adjusted at any time to adapt to the support of prefabricated T-beams of different heights, thereby improving the efficiency of the prefabricated T-beam transportation anti-overturning support; there is no need to purchase multiple support rods 2 of different models, thereby reducing the cost required for the prefabricated T-beam transportation anti-overturning support. After the prefabricated T-beam 9 is transported to the installation site, the support rod 2 can be adjusted to shorten, so that the support rod 2 can be separated from the prefabricated T-beam 9, which is very convenient. When supporting the prefabricated T-beam 9, each pair of support rods 2 is symmetrically arranged relative to the prefabricated T-beam 9, and each pair of support rods 2 and the beam transport vehicle plate 4 form a triangular stable structure to improve the support stability.

[0027] Specifically, the telescopic rod includes a screw rod 201 and a screw rod sleeve 202 threadably matched with the screw rod 201 .

[0028] The telescopic rod adopts a screw rod 201 and a screw rod sleeve 202 structure, and the structure is simple. For example, if the prefabricated T-beam 9 that is higher than the telescopic rod needs to be extended, the screw rod 201 is rotated forward with a wrench to extend the telescopic rod until the telescopic rod cooperates to support the prefabricated T-beam 9; if the prefabricated T-beam 9 that is lower than the telescopic rod needs to be shortened, the screw rod 201 is reversed with a wrench to shorten the telescopic rod until the telescopic rod cooperates to support the prefabricated T-beam 9. The operation is convenient, and the telescopic rod is always in a state that can be extended or shortened.

[0029] Preferably, a plurality of pairs of the support rods 2 are spaced apart along the length direction of the beam transport vehicle plate 4 .

[0030] The support rods 2 are multiple pairs, such as two pairs, three pairs, four pairs, five pairs, etc. Multiple pairs of support rods 2 provide a more reliable support for the prefabricated T-beams 9.

[0031] The distance between each pair of adjacent support rods 2 is D, 4m≤D≤6m.

[0032] The spacing between each pair of adjacent support rods 2 is 4m, 5m or 6m. For example, if the spacing between each pair of adjacent support rods 2 is 5m, the spacing between adjacent support rods 2 is 5m, which can better support the prefabricated T beams 9 without causing waste due to too many prefabricated T beams 9 or insecure support for the prefabricated T beams 9 due to too few support rods 2.

[0033] Preferably, an ear seat 3 is provided on the beam transport vehicle plate 4, and the fixed end of the support rod 2 is rotatably arranged on the ear seat 3 through a latch 10.

[0034] The steel ear seat 3 is welded or threadedly connected to the beam transport vehicle plate 4. Pin holes are provided at the ear seat 3 and the fixed end of the support rod 2. The pin 10 passes through one side of the ear seat 3, the fixed end of the support rod 2, and the other side of the ear seat 3 in sequence. The structure is simple and easy to turn.

[0035] Preferably, a support pad 1 is provided at the supporting end of the support rod 2, and the support pad 1 includes a flange support pad 101 and a web support pad 102 connected in a V-shape. When the support rod 2 supports the prefabricated T-beam 9, the flange support pad 101 and the web support pad 102 respectively abut against the flange and web corresponding to the prefabricated T-beam 9, and the flange support pad 101 and the web support pad 102 are arranged on both sides of the supporting end of the support rod 2.

[0036] The setting of the support pad 1 at the support end of the support rod 2 can increase the support area, provide better support for the precast T beam 9, and make the support more reliable and stable. Among them, the angle between the flange support pad 101 and the web support pad 102 is set according to the angle between the flange plate and the web plate of the precast T beam 9. When the support rod 2 is adjusted to support the precast T beam 9, the flange support pad 101 and the web support pad 102 are respectively against the flange and web plate corresponding to the precast T beam 9, and the flange support pad 101 and the web support pad 102 connected in a V-shape form a ""-shaped support with the support rod 2.

[0037] Preferably, a horseshoe limiting device is relatively arranged on the beam transport vehicle plate 4, and the horseshoe limiting device includes a baffle 5, a connecting rod 6, a rotating hand wheel 8 and a support 7. The support 7 is arranged on the beam transport vehicle plate 4, and a rotating hand wheel 8 is arranged at one end of the connecting rod 6. An external thread is arranged at the end of the connecting rod 6 close to the rotating hand wheel 8, and a screw hole matching the external thread is opened on the support 7. The other end of the connecting rod 6 passes through the screw hole and is connected to the baffle 5.

[0038] The horseshoe part of the lower end of the prefabricated T-beam is located between the horseshoe limiting devices arranged relatively, that is, the horseshoe part of the lower end of the prefabricated T-beam is located between the baffles 5 arranged relatively. Before the prefabricated T-beam is transported, the hand wheel 8 is rotated forward, and the two baffles 5 arranged relatively are close until they are against the horseshoe part of the lower end of the prefabricated T-beam; after the prefabricated T-beam is transported to the installation site, the hand wheel 8 is rotated in the reverse direction, and the two baffles 5 arranged relatively are separated until they are separated from the horseshoe part of the lower end of the prefabricated T-beam, which is very convenient to operate. The horseshoe limiting devices arranged relatively can limit the horseshoe part of the lower end of the prefabricated T-beam in transportation, effectively prevent the lower end of the prefabricated T-beam from moving during transportation, and make the lower end of the prefabricated T-beam firmly on the beam transport vehicle plate 4, cooperate with the support rod 2 to further improve the anti-overturning support quality of the prefabricated T-beam 9 in transportation, and improve the safety of the transportation of the prefabricated T-beam 9. The horseshoe limiting devices are one pair or multiple pairs, and the multiple pairs are at least two pairs. The connecting rod 6 is fixedly connected or rotatably connected to the baffle 5.

[0039] Preferably, the connecting rod 6 is rotatably connected to the baffle 5 via a ball head.

[0040] The connecting rod 6 is rotatably connected to the baffle 5 by the ball head, so that the baffle 5 fits tightly against the horseshoe part of the lower end of prefabricated T-beams of different models. For example, when the side wall of the horseshoe part of the lower end of the prefabricated T-beam has an inclined angle, the baffle 5 fits against the side wall of the horseshoe part of the lower end of the prefabricated T-beam through the rotation of the ball head, thereby further improving the firmness and stability of the horseshoe limit device supporting the horseshoe part of the lower end of the prefabricated T-beam.

[0041] Preferably, there are multiple pairs of horseshoe limiting devices, and the pairs of horseshoe limiting devices are arranged at intervals along the length direction of the beam transport vehicle plate 4.

[0042] There are multiple pairs of horseshoe limit devices, such as two pairs, three pairs, four pairs, five pairs, etc. The horseshoe limit devices are arranged at intervals along the length direction of the beam transport vehicle plate 4, and the interval between adjacent horseshoe limit devices is 4m, 5m or 6m. Multiple pairs of horseshoe limit devices provide a more reliable and stable support for the prefabricated T beam 9.

[0043] As a feasible implementation method, the support 7 and the baffle plate 5 are respectively a steel support and a steel baffle plate, and the steel support is welded or bolted to the beam transport vehicle plate 4.

[0044] The support 7 and the baffle 5 are respectively a steel support and a steel baffle, which increase the service life of the horseshoe limiting device.

[0045] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
