Abstract
Description
Technical Field
[0001] This utility model relates to bridge construction machinery, and more particularly to a mobile cap beam support trolley that facilitates cap beam construction. Background Technology
[0002] Cap beams are mainly used on the piers of bridges and elevated highways. In urban cap beam construction, to avoid affecting the normal traffic flow, cap beam supports are generally used. To save construction time, mobile support trolleys have emerged, with vehicles traveling beneath the cap beam supports and the mobile support trolley. Existing cap beam mobile support trolleys can generally only move in a straight line; when adjusting the position of the cap beam, they cannot perform upper or lower lateral adjustments, nor can they turn during movement. Summary of the Invention
[0003] To solve the above problems, the technical solution of this utility model is: a mobile cap beam support trolley, which includes a support truss, a top truss fixedly installed on the top of the support truss, a driving wheel and a driven wheel respectively installed at both ends of the bottom of the support truss, a lifting mechanism installed on both sides of the support truss, a lateral movement mechanism installed at the bottom of the lifting mechanism, and a steering mechanism installed on the driving wheel.
[0004] To facilitate the forward movement of the trolley and to enable the trolley to turn, a cylinder is fixedly installed at the bottom of the support truss. A rotating shaft is installed inside the cylinder via bearings, and a drive wheel is fixedly installed at the bottom of the rotating shaft. A drive motor is installed on the drive wheel.
[0005] To facilitate steering of the control vehicle, the steering mechanism includes a steering motor, with a gear one fixedly mounted on the output end of the steering motor, and a gear two fixedly mounted on the rotating shaft, wherein the gear one and the gear two mesh with each other.
[0006] To improve the stability of the trolley when it is stationary, the lifting mechanism includes a fixed seat and a limiting seat. A lifting cylinder is fixedly installed on the fixed seat, and a sliding sleeve with an open bottom is fixedly installed on the limiting seat. A sliding column is slidably installed inside the sliding sleeve. The piston end of the lifting cylinder passes through the top of the sliding sleeve and is fixedly connected to the sliding column. A transverse movement mechanism is installed at the bottom of the sliding column.
[0007] To enable the trolley to be adjusted laterally to better move to both sides, the lateral movement mechanism includes a limiting sleeve with a support foot that can slide laterally inside the limiting sleeve. A lateral movement cylinder is horizontally mounted on the limiting sleeve, and the piston end of the lateral movement cylinder is connected to the end of the support foot.
[0008] To facilitate the adjustment of the position of the cap beam support on the top truss, the fine-tuning mechanism is a hydraulic cylinder. One end of the hydraulic cylinder is connected to the middle of the top truss, and the other end is connected to the cap beam support by bolts.
[0009] To improve the stability of the trolley, anti-slip strips are fixedly installed on the bottom of the support legs.
[0010] To enhance the protection of the lifting cylinder and to increase its strength, a reinforcing plate is fixedly installed between the fixed seat and the limiting seat.
[0011] The beneficial effects of this utility model are:
[0012] When the trolley needs to be turned, the steering motor drives the second gear to rotate. Since the shaft is mounted inside the cylinder through bearings, the second gear can drive the shaft to rotate inside the cylinder, thereby driving the drive wheel to adjust the direction of travel.
[0013] When it is necessary to adjust the distance to both sides, the lateral movement mechanism is lowered by the lifting mechanism, and the lateral movement cylinder drives the support truss to move at the support feet, thereby achieving the purpose of adjusting the position of the cap beam.
[0014] Once the cap beam is placed on the trolley, if it is necessary to make minor adjustments to its position on the top truss, the position of the cap beam can be adjusted by extending and retracting the hydraulic cylinder, making the adjustment more convenient and quick.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] exist Figures 1 to 3A mobile cap beam support trolley comprises a support truss 1, a top truss 3 fixedly installed on the top of the support truss 1, a drive wheel 5 and a driven wheel 4 respectively installed at both ends of the bottom of the support truss 1, a lifting mechanism installed on both sides of the support truss 1, a transverse movement mechanism 16 installed at the bottom of the lifting mechanism, and a steering mechanism installed on the drive wheel 5.
[0022] Furthermore, a cylinder 9 is fixedly installed at the bottom of the supporting truss 1, and a rotating shaft is installed inside the cylinder 9 via a bearing. A drive wheel 5 is fixedly installed at the bottom of the rotating shaft, and a drive motor 6 is installed on the drive wheel 5.
[0023] Furthermore, the steering mechanism includes a steering motor 8, a gear 1 is fixedly mounted on the output end of the steering motor 8, and a gear 2 7 is fixedly mounted on the rotating shaft, with the gear 1 and gear 2 7 meshing with each other.
[0024] Furthermore, the lifting mechanism includes a fixed base 11 and a limiting base 15. A lifting cylinder 12 is fixedly installed on the fixed base 11, and a sliding sleeve 14 with a bottom opening is fixedly installed on the limiting base 15. A sliding column 10 is slidably installed inside the sliding sleeve 14. The piston end of the lifting cylinder 12 passes through the top of the sliding sleeve 14 and is fixedly connected to the sliding column 10. A transverse movement mechanism 16 is installed at the bottom of the sliding column 10.
[0025] Furthermore, the transverse movement mechanism 16 includes a limiting sleeve 161, on which a support leg 163 is provided that can slide laterally, and a transverse movement cylinder 162 is horizontally mounted on the limiting sleeve 161, with the piston end of the transverse movement cylinder 162 connected to the end of the support leg 163.
[0026] Furthermore, the fine-tuning mechanism is a hydraulic cylinder 17, one end of which is connected to the middle of the top truss 3, and the other end is connected to the cap beam support by bolts.
[0027] Furthermore, an anti-slip strip 164 is fixedly installed on the bottom of the support leg 163.
[0028] Furthermore, a reinforcing plate 13 is fixedly installed between the fixed base 11 and the limiting base 15.
[0029] During operation, the lifting mechanism is first activated, and the lifting cylinder 12 drives the support leg 163 to contact the ground. At this point, the cap beam is placed on the top truss 3, and then the lifting cylinder 12 retracts the support leg 163. The drive motor 6 is then activated, driving the drive wheel 5 to rotate forward. When the trolley's forward direction needs adjustment, the steering motor 8 is activated, driving the gear 7 to rotate, which in turn drives the drive wheel 5 to steer. After reaching the desired position, the lifting mechanism is activated again, and the lifting cylinder 12 drives the support leg 163 to contact the ground. When the position of the cap beam on both sides needs adjustment, the transverse cylinder 162 is activated, causing the support truss 1 to move left or right on the support leg 163, thus adjusting the cap beam's position.
[0030] The piston end of the hydraulic cylinder 17 is connected to the cover beam by bolts. When it is necessary to adjust the position of the cover beam on the top truss 3, the extension and retraction of the hydraulic cylinder 17 can be controlled to achieve the purpose of fine adjustment of the position of the cover beam support. When the cover beam is moved to the appropriate position, the cover beam and the top truss 3 are fixedly connected together by the fixing tie rod 18.
[0031] After moving the cover beam to the appropriate position via the support trolley, loosen the fixing rod 18 and then loosen the connection between the cover beam and the hydraulic cylinder 17.
[0032] To prevent the cap beam from sliding during construction, the fine-tuning mechanism does not use a sliding rail system to adjust its position. Because the fine-tuning distance is very small and the adjustment speed is very slow, a hard friction method is used for adjustment. To prevent damage to the trolley during hard friction, a small amount of grease can be added to the cap beam and the top truss support 3.
