Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, and particularly relates to a transverse beam erection platform for a combined transporter and erector. Background Technique

[0002] The most common beam erection scheme for the SLJ900 / 32 type mobile bridge erector (combined transporter and erector) is to use a 900t beam lifting machine to hoist the precast concrete box girder onto the beam erection pedestal. The bridge erector then traverses horizontally to above the precast concrete box girder, lifts the box girder, and directly drives away from the beam yard or traverses back to the beam transportation access road and drives away from the beam yard. This scheme requires the beam yard to be arranged beside the subgrade, with the same elevation as the subgrade or a beam transportation access road connecting the beam yard to the subgrade. For a beam yard located under the bridge on one side of the line, a 450t overline beam lifting machine is used to transfer the precast concrete box girder to the bridge deck, and then the SLJ900 mobile bridge erector is hoisted by the 450t overline beam lifting machine above the precast concrete box girder to be erected. After the bridge erector installs the beam, it drives away from the beam yard.

[0026] Please refer to Figures 1-5 , the present utility model provides a technical solution: a transverse beam erection platform of a combined girder transport and erection machine, including a vehicle body 1. Moving wheels 2 are rotatably connected to the bottom of the vehicle body 1, and support seats 3 are fixedly connected to the top of the vehicle body 1.

A connecting seat 12 is arranged on one side of the bottom of the beam erection platform 11 corresponding to the fourth rotating seat 10. The provided second hydraulic push rod 8 and the first hydraulic push rod 6 are independent driving elements. During the process of placing the beam body on an inclined bridge, by driving the second hydraulic push rod 8 arranged on one side, the first hydraulic push rod 6 can be rotated unilaterally under the rotational connection between the first rotating seat 5 and the support seat 3, and in cooperation with the telescopic effect of the first hydraulic push rod 6, the angle of the beam erection platform can be rotated and horizontally lifted to place the beam body, so as to facilitate adjustment according to the angle of the inclined bridge, thereby effectively improving the use convenience of the transverse beam erection platform. A clamping mechanism is arranged at the bottom of the beam erection platform 11.

[0027] In the present utility model, preferably, the first hydraulic push rod 6 is rotatably connected to the support seat 3 through the first rotating seat 5, and the second hydraulic push rod 8 is rotatably connected to the inclined block 4 through the second rotating seat 7.

[0028] In the present utility model, preferably, the output end of the second hydraulic push rod 8 is rotatably connected inside the third rotating seat 9.

[0029] In the present utility model, preferably, the fourth rotating seat 10 and the connecting seat 12 are rotatably connected.

[0030] In the present utility model, preferably, a guardrail 13 is fixedly connected to the top of the beam loading platform 11.

[0031] In the present utility model, preferably, the clamping mechanism includes a frame 14. A first bidirectional screw 15 is rotatably connected inside the frame 14. The first bidirectional screw 15 is fixedly connected to the output end of a first motor 16. Moving seats 17 are symmetrically and threadedly connected to the outer side of the first bidirectional screw 15. A support plate 18 is fixedly connected to the bottom of the moving seat 17. A second bidirectional screw 19 is rotatably connected inside the support plate 18. The second bidirectional screw 19 is fixedly connected to the output end of a second motor 20. Clamping claws 22 are symmetrically and threadedly connected to one end of the outer side of the second bidirectional screw 19. The height adjustment of the clamping mechanism is realized by using the first hydraulic push rod 6. Then, by driving the first motor 16, the moving seats 17 and the support plate 18 move relatively under the screw rotation of the first bidirectional screw 15, so as to be freely adjusted according to the length of the beam body. Then, by driving the second motor 20, the clamping claws 22 move relatively under the screw rotation of the second bidirectional screw 19, and then are adjusted and clamped according to the width of the beam body, so as to further improve the practicability of the device.

[0034] Working principle and usage process of the utility model: During use, this platform is based on the vehicle body 1, and the movement of the device is realized through the moving wheels 2 rotatably connected at the bottom. During the beam loading process, the inclined block 4 at the top of the support seat 3, the first hydraulic push rod 6 and the second hydraulic push rod 8 connected thereto work together to realize the angle adjustment and horizontal lifting of the beam loading platform 11. Specifically in operation, first, by driving the second hydraulic push rod 8, the first hydraulic push rod 6 rotates unilaterally under the rotational connection between the first rotating seat 5 and the support seat 3. At the same time, by utilizing the telescopic function of the first hydraulic push rod 6, the angle adjustment of the beam loading platform 11 is realized. On this basis, the first hydraulic push rod 6 continues to work to horizontally lift the beam loading platform 11 to the required height. The clamping mechanism at the bottom of the beam loading platform 11 is composed of a frame 14, a first bidirectional screw 15, a first motor 16, a moving seat 17, a support plate 18, a second bidirectional screw 19, a second motor 20 and clamping claws 22. By driving the first motor 16, the moving seat 17 and the support plate 18 move relatively under the screw rotation of the first bidirectional screw 15 to realize the adjustment of the beam length. Subsequently, the second motor 20 is driven to make the clamping claws 22 move relatively under the screw rotation of the second bidirectional screw 19 for clamping adjustment according to the width of the beam. In addition, the guardrail 13 ensures the safety of the top of the beam loading platform 11, while the limit plate 21 limits the movement range of the clamping claws 22 to prevent over-clamping. During the whole process, the rotational connection between the fourth rotating seat 10 and the connecting seat 12 enables the beam loading platform 11 to flexibly adjust the angle to meet the construction requirements of bridges with different inclination angles. Through this design, the transverse beam loading platform of the integrated beam transporting and erecting machine greatly improves the convenience and accuracy of beam placement in bridge construction.
