Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a prefabricated T-beam transportation anti-overturning device. Background Art

[0002] When transporting prefabricated T-beams from the prefabricated beam yard to the installation site, they need to pass through existing roads and construction access roads. The roads are all earth roadbeds with poor flatness, and they are prone to rollover during transportation. Therefore, the T-beams need to be reinforced to prevent overturning during transportation.

[0003] At present, the anti-overturning measure for T-beams is generally reinforced by diagonal braces, but this method only supports the two flange plates and the web of the T, and the support method is not flexible. It is necessary to set up supporting rods separately for beams of different heights. Therefore, it is necessary to set up a flexible and variable diagonal support method, and at the same time, set a limit on the horseshoe part of the T-beam, so that it can not only prevent overturning but also increase safety during transportation.

[0004] The patent document with patent announcement number CN219768632U proposes a prefabricated T-beam anti-overturning support safety device. The support heads on both sides can support the front and rear ends of the prefabricated beam through the support base on the lower side, the lower support rods on both sides and the upper support rods on both sides. The upper and lower support rods can be adjusted in length, and the fixed position of the support head can be adjusted more conveniently so that the support head can be stuck in the "T"-shaped corner of the prefabricated beam.

[0005] However, in the above technical solution, the support points are mainly concentrated at the positions of the two support heads. During the transportation of the T-beam, violent shaking may occur, which will cause the T-beam to only have support heads on both sides. There are fewer support points and a smaller support area, and the overall support stability is still lacking. There is still a safety hazard of the T-beam tipping over. Utility Model Content

[0006] In order to overcome the insufficient stability of the supporting structure in the prior art, the technical problem to be solved by the present invention is: how to improve the stability of the supporting structure.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] The prefabricated T-beam transportation anti-overturning device includes a base plate, the upper end of which is hinged with two groups of support rods for supporting both sides of the T-beam respectively, and the base plate is provided with a clamping assembly, which is used to clamp the bottom of the T-beam, support the T-beam on both sides through the support rods, and clamp the bottom of the T-beam through the clamping assembly at the same time, so as to achieve the support and stabilization effect of multiple support points, and can improve the T-beam to always maintain an upright stable posture under the clamping and supporting effect during transportation, so as to prevent the T-beam from tipping over and being damaged and the occurrence of safety accidents caused by tipping over.

[0009] Furthermore, an angular abutment plate is provided at one end of the support rod away from the base plate, and the included angle of the two supporting surfaces of the angular abutment plate is adapted to the included angle between the flange plate and the web of the T-beam; the angular abutment plate relies on the double support surfaces to achieve synchronous support for the flange plate and the web of the T-beam, thereby increasing the support area and preventing the support rod from sliding relative to the T-beam, thereby increasing the support strength.

[0010] Furthermore, the clamping assembly includes two movable blocks relatively arranged at the upper end of the base plate, an abutment gap for clamping the bottom of the T-beam is provided between the two movable blocks, and an adjusting member for adjusting the spacing of the abutment gap is also provided on the base plate, which further limits the specific structure of the clamping assembly, and abuts and supports the bottom end of the T-beam through the abutment gap to improve stability.

[0011] Furthermore, the above-mentioned adjusting member includes two connecting seats relatively arranged at the upper end of the above-mentioned base plate, the above-mentioned connecting seats are threadedly connected with a screw parallel to the base plate, the above-mentioned screw is connected to the above-mentioned moving block, and the end of the above-mentioned screw away from the above-mentioned moving block is connected to a handwheel. The handwheel applies a force to make the screw rotate and drive the moving block to move linearly on the base plate, so that the two moving blocks can move toward or away from each other, thereby adjusting the abutment gap spacing and position, which is easy to operate and has a simple structure.

[0012] Furthermore, the moving block is a rectangular plate vertically arranged on the base plate, the bottom end of the rectangular plate is in sliding contact with the upper end of the base plate, a convex ball is arranged at one end of the screw connected to the rectangular plate, and the rectangular plate is provided with a rotating cavity adapted to the convex ball, which further limits the shape of the moving block and the connection structure with the screw, and the moving stability can be improved through the sliding cooperation between the rectangular plate and the upper end of the base plate.

[0013] Furthermore, an ear seat for connecting the support rod is provided on the upper end of the base plate, and the ear seat is provided with a pin shaft. A pin hole for rotatably cooperating with the pin shaft is provided at the bottom of the support rod, which further limits the hinge structure of the support rod and the base plate. The structure is simple, easy to process and install, and has good connection strength.

[0014] Furthermore, the support rod is a telescopic rod hinged to the upper end of the base plate, and can be used to fix T-beams of different specifications and sizes through the telescopic structure, thereby improving the applicability of the device.

[0015] Furthermore, the telescopic rod includes a lower rod body, the lower end of the lower rod body is hinged to the base plate, the upper end of the lower rod body is provided with an axial screw hole, the upper rod body is threadedly connected in the screw hole, and one end of the upper rod body away from the lower rod body is used to abut the connecting part of the flange plate and the web of the T-beam, thereby further limiting the telescopic structure. The telescopic structure of the threaded rod is easy to operate and has a high connection strength.

[0016] Furthermore, an adjusting nut is connected to the outer wall of the lower rod body, and a rotating sleeve is rotatably sleeved on one end of the lower rod body close to the base plate. The end of the rotating sleeve away from the lower rod body is hinged to the base plate. The lower rod body is driven to rotate in the rotating sleeve by rotating the adjusting nut, thereby achieving the effect of screwing the upper rod body in and out of the screw hole.

[0017] The beneficial effects of the utility model are:

[0018] (1) By setting the clamping assembly, the support rod and the angled abutment plate can support the two sides of the T-beam while clamping the bottom of the T-beam, thereby further improving the fixing strength of the T-beam and reducing the probability of the T-beam tipping over and damaging and the safety hazards caused by tipping over.

[0019] (2) By setting the angled abutment plate, the flange plate and the web plate of the T-beam as well as the connection part between the flange plate and the web plate can be abutted at the same time, so that the supporting area is large and it is not easy to slide relative to the T-beam. In addition, since the inclination angle of the angled abutment plate is adapted to the angle between the flange plate and the web plate of the T-beam, the abutment surface of the angled abutment plate is completely and tightly fitted with the flange plate and the web plate of the T-beam as well as the connection part between the flange plate and the web plate, thereby improving the supporting strength and stability.

[0026] The utility model is further described below in conjunction with the accompanying drawings.

[0027] according to Figure 1-Figure 3 As shown, this embodiment proposes a prefabricated T-beam 4 transportation anti-overturning device, including a base plate 1, and two groups of support rods 2 are hinged on the upper end of the base plate 1 for supporting both sides of the T-beam 4 respectively. A clamping assembly is also arranged on the upper end of the base plate 1, and the clamping assembly is used to clamp the bottom of the T-beam 4.

[0028] The support rod 2 is provided with an angled abutment plate 3 at one end away from the bottom plate 1, and the inclination angle of the angled abutment plate 3 is adapted to the angle between the flange plate 41 and the web plate 42 of the T beam 4; specifically, the T beam 4 comprises a transversely arranged flange plate 41 and a web plate 42 vertically connected to the lower end of the flange plate 41, and the overall cross-section is T-shaped, and the two sides of the web plate 42 are connected to the flange plate 41 to form an angle of the T beam 4, and the angle of the supporting surfaces on both sides of the angled abutment plate 3 is adapted to the angle between the flange plate 41 and the web plate 42 of the T beam 4. 4, so that the two abutting surfaces of the angle abutting plate 3 are closely fitted to the side wall of the web plate 42 and the bottom wall of the flange plate 41 respectively, and the angled portion of the angle abutting plate 3 is fitted to the connecting portion of the flange plate 41 and the web plate 42, forming a limiting effect on the angle abutting plate 3, and the size of the angle abutting plate 3 is designed relative to the actual size of the T beam 4, ensuring that there is sufficient supporting strength and friction between the angle abutting plate 3 and the T beam 4, thereby achieving a stable supporting effect on the T beam 4.

[0029] Specifically, the clamping assembly stably clamps the bottom end of the web 42, so that the fixing point of the whole device to the T beam 4 is more balanced. During the transportation of the T beam 4, after a large degree of shaking occurs, the clamping assembly and the support rod 2 simultaneously support the T beam 4 to be stably fixed on the bottom plate 1, thereby improving stability. For the specific structure of the clamping assembly, such as Figure 3 As shown, the clamping assembly includes two moving blocks 7 relatively arranged at the upper end of the base plate 1, an abutment gap for clamping the bottom of the T-beam 4 is provided between the two moving blocks 7, and an adjusting member for adjusting the spacing and position of the abutment gap is also provided on the base plate 1; when in use, the two moving blocks 7 are adjusted by the adjusting member to move toward or away from each other at the upper end of the base plate 1, thereby adjusting the size of the abutment gap, so that the bottom end of the T-beam 4 is stably limited in the abutment gap, thereby achieving a fixing effect on the T-beam 4.

[0030] Furthermore, the adjusting member includes two connecting seats 5 relatively arranged at the upper end of the base plate 1, the connecting seat 5 is threadedly connected with a screw 6 parallel to the base plate 1, the screw 6 is connected to the moving block 7, and the end of the screw 6 away from the moving block 7 is connected with a handwheel 8. When in use, the operator turns the handwheel 8 to make the screw 6 threadably rotate relative to the connecting seat 5, and the screw 6 produces a linear movement relative to the connecting seat 5 and drives the moving block 7 to adjust the abutment gap size, and the threaded connection structure is relatively stable and can ensure sufficient abutment strength.

[0031] Moreover, the above-mentioned moving block 7 can be an abutment plate fixed on the screw rod 6, and the abutment plate does not contact the upper end of the bottom plate 1. The abutment plate can rotate with the screw rod 6 and realize linear movement to realize the adjustment of the abutment gap size. Preferably, the above-mentioned moving block 7 is a rectangular plate vertically arranged with the above-mentioned bottom plate 1, and the bottom end of the above-mentioned rectangular plate slides in contact with the upper end of the above-mentioned bottom plate 1. The end of the above-mentioned screw rod 6 connected to the above-mentioned rectangular plate is provided with a convex ball 9, and the above-mentioned rectangular plate is provided with a rotating cavity adapted to the above-mentioned convex ball 9; when in use, the screw rod 6 is driven to move by rotating the hand wheel 8, and the convex ball 9 is rotated in the rotating cavity, thereby pushing the rectangular plate to realize linear sliding on the upper end of the bottom plate 1, and the rectangular plate is vertically arranged relative to the bottom plate 1, and there is an abutment gap between the two rectangular plates. The abutment surfaces of the two rectangular plates respectively abut the two side walls of the web 42, and the rectangular plate and the side walls of the web 42 are tightly fitted to ensure the stability of clamping.

[0032] In addition, with respect to the support rod 2, one end of the support rod 2 close to the bottom plate 1 is hinged to the upper end of the bottom plate 1. Figure 4 As shown, the specific hinge structure is: an ear seat 10 for connecting the above-mentioned support rod 2 is arranged at the upper end of the base plate 1, and the above-mentioned ear seat 10 is provided with a pin shaft 11. The bottom of the above-mentioned support rod 2 is provided with a pin hole for rotationally cooperating with the above-mentioned pin shaft 11. The pin shaft 11 and the pin hole are both adapted cylindrical. In the working state, the pin shaft 11 and the pin hole rotate relative to each other, so that the support rod 2 can rotate relative to the ear seat 10 and the base plate 1 to achieve angle adjustment, which facilitates the angular abutment plate 3 of the support rod 2 to be accurately supported at the connection position of the flange plate 41 and the web plate 42 of the T-beam 4.

[0033] Moreover, in actual work, there are many specifications of T-beams 4. In order to adapt to T-beams 4 of different specifications and sizes, the support rod 2 is a telescopic rod hinged to the upper end of the base plate 1. That is to say, by adjusting the length of the support rod 2 and the angle of the support rod 2 relative to the base plate 1, the angle abutment plate 3 can be stably abutted against the connection position of the flange plate 41 and the web plate 42 of the T-beam 4, ensuring that a stable clamping effect can be achieved for T-beams 4 of different specifications.

[0034] Moreover, the telescopic rod can specifically be a telescopic structure composed of a sleeve, a telescopic rod inserted into the sleeve, and a fixing mechanism cooperated with a corresponding pin hole and pin shaft 11. Further, the telescopic rod can also include a lower rod body 21, the lower end of the lower rod body 21 is hinged to the base plate 1, an axial screw hole is provided at the upper end of the lower rod body 21, an upper rod body 22 is threadedly connected in the screw hole, and one end of the upper rod body 22 away from the lower rod body 21 is used to abut against the connection part of the flange plate 41 and the web plate 42 of the T-beam 4. When in use, the upper rod body 22 and the lower rod body 21 are relatively rotated, so that the upper rod body 22 is displaced in the screw hole to achieve a telescopic effect. The threaded structure has strong connection stability and high connection stability, and is easy to operate.

[0035] Specifically, according to Figure 4 , 5 As shown, the outer wall of the lower rod body 21 is connected with an adjusting nut 24, and the end of the lower rod body 21 close to the base plate 1 is rotatably sleeved with a rotating sleeve 23, and the end of the rotating sleeve 23 away from the lower rod body 21 is hinged to the base plate 1. By rotating the adjusting nut 24, the lower rod body 21 is driven to rotate in the rotating sleeve 23, so that the upper rod body 22 can be screwed in and out of the screw hole. On the basis of ensuring the stability of the hinge, the length of the telescopic rod can be adjusted by telescoping the upper and lower rod bodies.

At the same time, the structure of the entire device is simple, convenient for processing and molding, and has good economy.
