Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge construction equipment, and particularly relates to a positioning device for erecting a T-beam frame. Background Art

[0002] Curved bridges have unique designs and the ability to adapt to complex terrains, and are widely used in mountainous cities and other places. In order to effectively accelerate the construction progress, beam frames are usually prefabricated centrally in prefabrication yards, and then transported to the bridge site by beam-transporting gun carriages and erected by beam-erecting equipment.

[0003] However, when the beam-transporting gun carriage transports the beam, the precast T-beam frame is simply placed on the beam-transporting gun carriage and roughly fixed by steel pipes supplemented with steel wire ropes and manual hoists. When the precast T-beam frame is transported to the erection site, the precast T-beam frame is prone to displacement, and the center line of the precast T-beam frame cannot be aligned. When the precast T-beam frame is erected by the beam-erecting equipment subsequently, adjusting the position of the precast T-beam frame in the air increases the operation difficulty and risk. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a positioning device for erecting a T-beam frame, so as to solve the technical problem that when the precast T-beam frame is erected by the beam-erecting equipment in the prior art, adjusting the position of the precast T-beam frame in the air increases the operation difficulty and risk.

[0005] The utility model is realized through the following technical solutions:

[0006] A positioning device for erecting a T-beam frame includes a base. Along the length direction of the base, mounting grooves are respectively formed at the surface corners of the base. Each mounting groove is detachably installed with a mounting plate, and a first power source is fixedly provided at the top of the mounting plate. The output ends of multiple first power sources are opposite to each other in pairs along the width direction of the base;

[0007] An installation disk, a push rod and a first support positioning plate are sequentially installed along the movement direction of the output end of the first power source. The installation disk, the push rod and the first support positioning plate are fixedly connected in sequence, and multiple groups of auxiliary support components are arranged between the installation disk and the first support positioning plate.

[0008] Further, a plurality of grooves are arranged in a circumferential array on the circumferential surface of the installation disk. The auxiliary support component includes a connecting rod fixedly connected to the groove, and a support rod is hinged to the connecting rod;

[0009] One end of the support rod away from the connecting rod is hinged with a support seat, and the support seat is fixedly connected with the first support positioning plate.

[0010] Further, along the length direction of the base, a second power source is installed between two adjacent first power sources. The output end of the second power source faces upward, and a second support positioning plate is fixedly installed at the output end.

[0011] Further, along the length direction of the base, a roller support frame is installed in the middle of the surface of the base, and a plurality of conveyor rollers are installed in the roller support frame.

[0012] Further, a pressure sensor is installed on the first support positioning plate.

[0013] Further, both the first power source and the second power source adopt multi-stage hydraulic cylinders.

[0014] Further, a support frame for supporting the piston rod of the first power source is fixedly connected to the base.

[0015] The beneficial effects of the present utility model are as follows:

[0016] When the T-beam frame erection positioning device of the present utility model is in use, when erecting a precast T-beam frame, the base is fixed to a preset position on the ground through anchor bolts, and the precast T-beam frame is lifted from the beam transport gun car to the base by using an external beam lifting device. After lifting, the external hydraulic system is controlled to make the four first power sources distributed in a rectangular shape act simultaneously, so as to respectively push the first support positioning plates to support the side of the beam rib of the precast T-beam frame. Multiple power sources cooperate simultaneously to center and clamp the precast T-beam frame, realizing the centering positioning of the precast T-beam frame and ensuring the positioning accuracy during the erection of the precast T-beam frame.

[0017] The present utility model first lifts the precast T-beam frame to the preset positioning device on the ground for positioning and then erects it. Compared with the prior art of directly lifting and erecting the precast T-beam frame on the beam transport gun car, it has the following advantages:

[0018] Firstly, the ground positioning device allows construction workers to accurately adjust the position and angle of the precast T-beam frame in a stable ground environment, ensuring accurate docking during installation and avoiding the difficulty and risk of in-air adjustment.

[0019] Secondly, the preparation work of the precast T-beam frame, including positioning, inspection and necessary correction, is completed in advance on the ground to ensure that the precast T-beams meet the design requirements before erection, thereby accelerating the overall erection process and reducing the waiting and adjustment time during the erection process.

[0020] Finally, the present utility model performs multi-point inclined support on the back of the first support positioning plate through multiple groups of the auxiliary support components, improving the anti-tipping effect of the device on the precast T-beam frame. Description of the Drawings

[0027] Typical implementation manners reflecting the features and advantages of the present utility model will be specifically described in the following description. It should be understood that the present utility model can have various changes in different implementation manners, all of which do not depart from the scope of the present utility model, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present utility model.

[0028] In the description of the present application, the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0029] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a positioning device for erecting T-shaped beams, including a base 1, and lugs are respectively installed at four corners of the base 1 for fixing the base 1. Along the length direction of the base 1, installation grooves 2 are respectively formed at the surface corners of the base 1, and a mounting plate 3 is detachably installed in each installation groove 2 by means of bolt fixation;

[0030] A first power source 4 is fixedly installed on the top of the mounting plate 3. The output ends of multiple first power sources 4 are pairwise opposite along the width direction of the base 1. The first power source 4 adopts a multi-stage hydraulic cylinder, so that the stroke of the power source becomes longer, improving the applicability of the lifting device. A support frame 15 for supporting the piston rod of the first power source 4 is fixedly connected to the base 1 to ensure the stability of the first power source 4 during operation.

[0031] An installation disk 5, a push rod 6, and a first support and positioning plate 7 are sequentially installed along the action direction of the output end of the first power source 4. The installation disk 5, the push rod 6, and the first support and positioning plate 7 are fixedly connected in sequence. Multiple groups of auxiliary support components 8 are arranged between the installation disk 5 and the first support and positioning plate 7. Preferably, three groups of the auxiliary support components 8 are obliquely installed behind each first support and positioning plate 7 to form a stable support structure between the installation disk 5 and the first support and positioning plate 7.

[0032] When the T-beam frame erection positioning device of the present invention is in use, when erecting a precast T-beam frame, the base 1 is fixed to a preset position on the ground through anchor bolts, and the precast T-beam frame is lifted from the beam transport vehicle to the base 1 by using an external beam lifting device. After lifting, the external hydraulic system is controlled to make the four first power sources 4 distributed in a rectangle act simultaneously to respectively push the first support and positioning plate 7 to support the side of the beam rib of the precast T-beam frame. Multiple power sources cooperate simultaneously to centeringly clamp and fix the precast T-beam frame, realizing the centering positioning of the precast T-beam frame and ensuring the positioning accuracy during the erection of the precast T-beam frame.

[0033] By first lifting the precast T-beam frame to be positioned in the preset positioning device on the ground and then erecting it, the T-beam frame erection positioning device of the present invention has the following advantages compared with directly lifting the precast T-beam frame on the beam transport vehicle for erection in the prior art:

[0034] First, the ground positioning device allows construction workers to accurately adjust the position and angle of the precast T-beam frame in a stable ground environment, ensuring accurate docking during installation and avoiding the difficulty and risk of aerial adjustment.

[0035] Second, the preparatory work of the precast T-beam frame, including positioning, inspection, and necessary corrections, is completed in advance on the ground to ensure that the precast T-beam meets the design requirements before erection, thereby accelerating the overall erection process and reducing the waiting and adjustment time during the erection process.

[0036] Finally, the device of the present invention performs multi-point inclined support behind the first support and positioning plate 7 through multiple groups of the auxiliary support components 8, improving the anti-tipping effect of the device on the precast T-beam frame.

[0037] Please refer to Figure 1 andFigure 3 On the circumferential surface of the mounting disc 5, a plurality of grooves 81 are arranged in a circumferential array. The auxiliary support assembly 8 includes a connecting rod 82 fixedly connected to the groove 81, and a support rod 83 is hinged to the connecting rod 82;

[0038] One end of the support rod 83 away from the connecting rod 82 is hinged with a support seat 84, and the support seat 84 is fixedly connected to the first support positioning plate 7. The support rod 83 is obliquely installed between the mounting disc 5 and the first support positioning plate 7 for support, so as to improve the support effect of the first support positioning plate 7 on the precast T-beam frame, thereby ensuring the stability during the erection process of the precast T-beam frame.

[0039] Please refer to Figure 1 , along the length direction of the base 1, a second power source 9 is installed between two adjacent first power sources 4. The output end of the second power source 9 faces upward, and a second support positioning plate 10 is fixedly provided at its output end. When the precast T-beam frame is lifted and placed on the base 1, the second power source 9 pushes the second support positioning plate 10 to rise to support the horizontal part of the precast T-beam frame, thereby enhancing the positioning effect of the device on the precast T-beam frame. And rubber pads are installed on both the first support positioning plate 7 and the second support positioning plate 10 to increase the friction with the surface of the precast T-beam frame, further improving the stability between the precast T-beam frame and the support positioning plate.

[0040] Please refer to Figure 1 , along the length direction of the base 1, a roller frame 11 is installed in the middle of the surface of the base 1, and a number of conveyor rollers 12 are installed in the roller frame 11. When the precast T-beam frame is lifted and placed on the base 1, by lifting the precast T-beam frame into the roller frame 11, it can play a role in primary positioning of the precast T-beam frame, and the rotation of the conveyor rollers 12 is beneficial to the movement of the precast T-beam frame in the roller frame 11, so as to reach the effect of facilitating the adjustment of the position of the precast T-beam frame.

[0041] Please refer to Figure 2 , a pressure sensor 13 is installed on the first support positioning plate 7. By each pressure sensor 13 detecting the supporting force of the corresponding first power source 4 pushing the first support positioning plate 7 against the precast T-beam frame, the control system analyzes the difference in the supporting force between multiple pressure sensors 13. If the precast T-beam frame is not centered, there is a difference in the supporting force between the pressure sensors 13. At this time, the control system controls the output end of the corresponding first power source 4 with a difference from the preset supporting force to retract or extend, relaxing the clamping on the precast T-beam frame, thereby performing left-right lateral fine adjustment on the precast T-beam frame to achieve centering, and further ensuring the positioning accuracy during the erection of the precast T-beam frame.

[0042] Finally, it should be noted that the above embodiments are only the preferred embodiments of the present utility model, and cannot be used to limit the scope of protection of the present utility model. Any non-substantive changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
