Description

Technical Field

[0001] The utility model relates to the technical field of T-beam longitudinal slope adjustment, in particular to a prefabricated T-beam longitudinal slope adjustment device for bridge engineering. Background Art

[0002] The slope of T-beams needs to be adjusted during construction. Traditional T-beam longitudinal slope adjustment only directly supports the top plate through threaded rods, resulting in uneven force on the top plate. At the same time, the threaded rods have no rotating handles, and tools are required for adjustment, which reduces construction efficiency. At the same time, traditional T-beam longitudinal slope adjustment devices can only adjust the slope, and it is difficult to adjust the overall height. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the existing technology and provide a prefabricated T-beam longitudinal slope adjustment device for bridge engineering to solve the shortcomings of traditional T-beam longitudinal slope adjustment devices such as low construction efficiency and difficulty in height adjustment. It can not only make the top plate force more balanced, but also make it easier to adjust the screw rod, and can also adjust the overall height of the T-beam at the same time, thereby improving construction efficiency.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a longitudinal slope adjustment device for prefabricated T-beams in bridge engineering, comprising a top plate, a bottom plate, and a slope adjustment mechanism arranged between the top plate and the bottom plate, wherein the slope adjustment mechanism is provided with more than two pairs, and each pair of slope adjustment mechanisms is longitudinally aligned, and the slope adjustment mechanism comprises an upper screw sleeve hinged to the top plate, and a lower screw sleeve fixed to the bottom plate, a screw is sleeved between the upper screw sleeve and the lower screw sleeve, and a rotating plate is further provided between the top plate and the upper screw sleeve, and the rotating plate is hinged to the upper screw sleeve.

[0005] Furthermore, the upper screw sleeve and the lower screw sleeve are threadably connected to the screw via internal threads, and the internal threads of the upper threaded sleeve and the lower threaded sleeve are in opposite directions.

[0006] Furthermore, a rotating handle is provided on the screw rod, and a rib is provided between the lower screw rod sleeve and the bottom plate.

[0007] Furthermore, a synchronous lifting mechanism is provided between each pair of slope adjustment mechanisms;

[0008] The synchronous lifting mechanism includes two nuts respectively sleeved on two screws, a turbine is fixed on the outer peripheral side of each nut, and a worm connected to the two turbines, and the worm synchronously adjusts the rotation of the two turbines.

[0009] Furthermore, a synchronous lifting mechanism support frame is provided on the bottom plate, a support shell is provided on the synchronous lifting mechanism support frame, and the nut, turbine and worm are all provided in the support shell.

[0010] Furthermore, the screw is fixedly connected to the upper screw sleeve and movably connected to the lower screw sleeve.

[0011] Furthermore, a lifting handle is provided at one end of the worm.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The rotating plate of the utility model is hinged with the upper screw sleeve to make the force on the top plate more balanced. The rotation of the screw can be directly adjusted by rotating the handle, thereby improving construction efficiency. At the same time, the overall height of the device can also be adjusted. The synchronous lifting mechanism enables the screws of a pair of slope adjustment mechanisms to be lifted and lowered synchronously, without the need for repeated debugging, and the slope adjustment work can be completed quickly.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Example 1:

[0023] like Figure 1-2As shown, a longitudinal slope adjustment device for prefabricated T-beams in bridge engineering comprises a top plate 1, a bottom plate 8, and a slope adjustment mechanism disposed between the top plate 1 and the bottom plate 8. The slope adjustment mechanisms are provided in three pairs and arranged transversely, with each pair of slope adjustment mechanisms aligned longitudinally.

[0024] The slope adjustment mechanism includes an upper screw sleeve 3 hinged to the top plate 1 and a lower screw sleeve 6 fixed to the bottom plate 8. A screw 4 is sleeved between the upper and lower screw sleeves 3 and 6. A rotating plate 2 is also provided between the top plate 1 and the upper screw sleeve 3 and hinged to the upper screw sleeve 3. The middle pair of slope adjustment mechanisms are larger than the two side ones and also serve as support.

[0025] The upper and lower screw sleeves 3 and 6 are threadedly connected to the screw rod 4 via internal threads. The internal threads of the upper and lower screw sleeves 3 and 6 are in opposite directions. Ribs 7 are provided between the lower screw sleeve 6 and the base plate 8. A rotary handle 5 is provided on the screw rod 4. Turning the rotary handle 5 changes the overall length of the upper and lower screw sleeves 3, 4, and 6. Adjusting the different slope adjustment mechanisms to different lengths changes the slope of the top plate 1.

[0026] Example 2:

[0027] like Figure 3-5 As shown, a longitudinal slope adjustment device for prefabricated T-beams in bridge engineering comprises a top plate 1, a bottom plate 8, and a slope adjustment mechanism disposed between the top plate 1 and the bottom plate 8. The slope adjustment mechanisms are provided in three pairs and arranged transversely, with each pair of slope adjustment mechanisms aligned longitudinally.

[0028] The slope adjustment mechanism includes an upper screw sleeve 3 hinged to the top plate 1 and a lower screw sleeve 6 fixed to the bottom plate 8. A screw 4 is sleeved between the upper screw sleeve 3 and the lower screw sleeve 6. A rotating plate 2 is also provided between the top plate 1 and the upper screw sleeve 3, and the rotating plate 2 is hinged to the upper screw sleeve 3. A synchronous lifting mechanism is provided between each pair of slope adjustment mechanisms.

[0029] The synchronous lifting mechanism includes two nuts 9 respectively sleeved on two screws 4. A turbine 10 is fixed to the outer periphery of each nut 9. At the same time, a worm 11 is connected to the two turbines 10. The worm 11 synchronously adjusts the rotation of the two turbines 10. A lifting handle 12 is provided at one end of the worm 11. A synchronous lifting mechanism support frame 13 is provided on the base plate 8. A support shell 14 is provided on the synchronous lifting mechanism support frame 13. The nuts 9, turbine 10, and worm 11 are all arranged in the support shell 14. The upper and lower ends of the screw 4 extend to the outside of the support shell 14. The screw 4 is fixedly connected to the upper screw sleeve 3 and movably connected to the lower screw sleeve 6.

[0030] When the lifting handle 12 is rotated, the worm 11 rotates accordingly, and at the same time drives the two turbines 10 to rotate synchronously. The turbine 10 drives the nut 9 to rotate. Since the nut 9 and the screw 4 are threadedly connected, and the two ends of the screw 4 are restricted and cannot rotate, the screw 4 performs a lifting movement under the rotation of the nut 9, thereby extending or shortening the overall length of the slope adjustment mechanism, thereby realizing the synchronous adjustment of a group of slope adjustment mechanisms.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
