Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge construction, in particular to a mobile platform. Background Art

[0002] During the construction of some bridges, such as the installation and docking of steel box girders and weld inspection, it is necessary to use auxiliary construction facilities to get close to the construction work surface. Sometimes, due to the constraints of the environmental conditions of the bridge, it is impossible to set up a construction scaffold under the bridge or even if a scaffold is set up, it is not convenient for construction. In this case, a construction platform is needed for auxiliary construction.

[0003] Traditionally, after moving to a suitable position, some mobile platforms used for highway bridge and tunnel construction are directly fixed using the brake pads of the universal wheels. However, the mobile wheels are easily damaged by external forces after being supported for a long time, which not only reduces the service life of the mobile platform, but also affects the construction use of the workers. The mobile wheel support method cannot stably fix the entire device in a certain position, and the device needs to be fixed with tools. This is not only time-consuming and labor-intensive, but also reduces the use efficiency of the mobile platform. In addition, the stability of the overall support of the device is poor, which seriously affects the safety of construction workers during operation. Utility Model Content

A connecting plate 4 is fixedly connected to the upper middle of the inner wall of the base 1. The connecting plate 4 is used to position the parts. A supporting block 5 is fixedly connected to the middle of the bottom of the connecting plate 4. The supporting block 5 is used to support the parts. A connecting rod 6 is penetrated and rotatably connected to the surface of the supporting block 5. The connecting rod 6 is used to connect the parts on both sides. A moving mechanism 7 is arranged inside the base 1. The moving mechanism 7 is used to control the lifting of the bottom parts. A mounting plate 8 is arranged at the bottom of the base 1. The mounting plate 8 is used to install parts. Both sides of the middle of the top of the mounting plate 8 are fixedly connected with screw rods 9. The screw rods 9 are used in conjunction with the moving mechanism 7 to control the installation The plate 8 and the parts at its bottom move up and down, and moving wheels 10 are installed at the four corners of the bottom of the mounting plate 8. The moving wheels 10 are used to drive the device as a whole to move. Telescopic rods 11 are installed at the four corners of the top of the mounting plate 8. The top and bottom of the telescopic rods 11 are fixedly connected to the top of the inner wall of the base 1 and the top of the mounting plate 8 respectively. The telescopic rods 11 are used to assist the moving mechanism 7 to move and improve the stability of the mounting plate 8 and the moving wheels 10 when they move up and down. Receiving grooves 12 are opened at the left and right places on both sides of the base 1. The positions of the receiving grooves 12 correspond to each other. Support mechanisms 13 are arranged inside the receiving grooves 12. The number of support mechanisms 13 is consistent with that of the receiving grooves 12. The support mechanisms 13 on both sides of the base 1 are symmetrically arranged. The support mechanisms 13 are used to assist in supporting the base 1 and improve the stability of the device when it is fixed, so that the device will not tip over casually during use.

[0021] The moving mechanism 7 includes a servo motor 71 installed on the base 1 for movement. Both ends of the connecting rod 6 are fixedly connected with a worm 72. One side of the worm 72 is fixedly connected to one side of the output shaft of the servo motor 71. The surface of the worm 72 is meshed with a worm wheel 73. The top of the worm wheel 73 is fixedly embedded with a moving shell 74. The top of the moving shell 74 is rotatably connected to the inner wall of the base 1. The number of the moving shell 74 is the same as that of the screw 9. The surface of the screw 9 is threadedly connected to the inner wall of the moving shell 74. The servo motor 71 controls the worm 72 to rotate. At the same time, the worm 72 and The meshing transmission of the worm gear 73 drives the moving shell 74 to rotate synchronously. The moving shell 74 is threadedly connected to the screw rod 9, which drives the mounting plate 8 and the moving wheel 10 at the bottom of the screw rod 9 to move up and down, so as to adjust the height of the moving wheel 10. When using the mobile platform, the moving wheel 10 is folded up to prevent the moving wheel 10 from being damaged by a large external force for a long time. During the process of folding the moving wheel 10, the telescopic rod 11 is used to ensure stability. After the moving wheel 10 is folded, it can be supported by the base 1, which does not affect the normal use of the device and prolongs the service life of the mobile platform.

[0022] The support mechanism 13 includes a support rod 131 hinged to the top of the inner wall of the storage groove 12, the inner side of the support rod 131 is inclined, the number of the support rods 131 is consistent with the storage groove 12, the inner side of the support rod 131 is provided with a moving groove 132, the cross-sectional shape of the moving groove 132 is T-shaped, the moving groove 132 is also inclined, and the inclination angle is consistent with the inclined surface of the support rod 131, the left and right sides of both sides of the mounting plate 8 are fixedly connected with connecting blocks 133, the position of the connecting block 133 corresponds to the support rod 131, the inside of the moving groove 132 is slidably connected with a moving block 134, and the moving block 134 is slidably connected to the inside of the moving groove 132. One side of 34 is cylindrically set to adapt to the shape of the movable groove 132. When the mounting plate 8 drives the movable wheel 10 to move upward, the movable block 134 is driven to move upward along the inner wall of the movable groove 132 through the connecting block 133. Through the inclined setting of the movable groove 132, the support rod 131 is pushed outward to tilt its angle. When the bottom of the base 1 contacts the ground, the support rod 131 tilts outward to provide auxiliary support for the entire device, thereby improving the stability of the device when it is fixed, improving the safety of the staff during operation, and reducing the risk of the device tipping over and causing danger to the staff.

[0023] It is worth noting that the lifting frame 2 proposed in this technical solution is a prior art, and its working principle and beneficial effects when used are not described in detail here.

[0024] Working principle: first move the mobile platform to the position where construction work is required, then turn on the servo motor 71, and control the worm 72 to rotate through the servo motor 71, and at the same time drive the moving shell 74 to rotate through the meshing transmission of the worm 72 and the worm wheel 73, so as to control the screw rod 9 and the mounting plate 8 and the moving wheel 10 at its bottom to move upward, so that the bottom of the base 1 contacts the ground, and the moving wheel 10 is stored, thereby reducing the risk of the moving wheel 10 being damaged by external force for a long time. While the mounting plate 8 rises, the connecting block 133 drives the moving block 134 to slide along the inner wall of the moving groove 132, and the support rod 131 is propped up outward, so that the support rod 131 is tilted outward with the hinge point as the axis, so as to support the mobile platform, improve stability, and avoid injuries to workers due to instability during operation. After the mobile platform is fixed, the lifting frame 2 drives the working platform 3 to rise for construction work.
