Technical Field

[0001] This utility model relates to the field of engineering supervision technology, specifically a platform monitoring trolley. Background Technology

[0002] When workers need to perform monitoring operations at height, they need to use a lifting platform or a support scaffold to raise them. The lifting platform is more flexible than the support scaffold.

[0003] To make high-altitude monitoring operations more efficient, the lifting platform of a typical lifting vehicle is designed with an extended platform. However, when workers move to the edge of the extended platform, the device may tilt due to the shift in the center of gravity. This tilted platform poses a safety hazard to workers operating at heights. Therefore, it is necessary to design a platform monitoring trolley that remains stable even when workers move to the edge of the platform. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a platform monitoring carrier trolley, including a mobile vehicle body 4, a hydraulic lifting frame 3 fixedly connected to the top of the mobile vehicle body 4, a carrier platform 2 fixedly connected to the top of the hydraulic lifting frame 3, a fixed pipe 5 provided at the bottom of the carrier platform 2, a connecting rod 7 slidably connected to the inner wall of the fixed pipe 5, support blocks 12 fixedly connected to both sides of the fixed end of the bottom of the hydraulic lifting frame 3, a support platform 11 fixedly connected to the top of the support blocks 12, an electric push rod 10, a gear 18, a gear 2 18, a fixed slider 14, and a fixed slider 2 16 fixedly connected to the top of the support platform 11, an electric push rod 10, a gear 18, a fixed slider 14, and a fixed slider 2 16 fixedly connected to the top of the support platform 11, an active rack 9 fixedly connected to the telescopic end of the electric push rod 10, and the two sides of the active rack 9 are respectively connected to the gear 18 and the gear 2 18. The eight-phase meshing and locking mechanism consists of movable racks 15 and 17 slidably connected to the inner walls of fixed slider 14 and fixed slider 2 16, respectively. Movable rack 15 meshes and locks with gear 2 18, and movable rack 2 17 meshes and locks with gear 1 8. The bottom of movable rack 15 slides against the top of the driving rack 9, and the top of movable rack 2 17 slides against the bottom of the driving rack 9. Insert pins 19 are fixedly connected to the ends of movable rack 15 and movable rack 2 17 near the fixed tube 5, which can control the separation or fixing of the fixed tube 5 and the connecting rod 7. Locking grooves are opened on both sides of the fixed tube 5 and the connecting rod 7, and the side of the insert pin 19 is movably inserted into the inner wall of the locking groove.

[0023] Furthermore, both the fixed tube 5 and the connecting rod 7 have reinforcing grooves on their sides to further improve the stability when the fixed tube 5 and the connecting rod 7 are connected. The end of the active rack 9 away from the electric push rod 10 is movably inserted into the inner wall of the reinforcing groove.

[0024] Furthermore, both sides of the movable rack 15 and movable rack 2 are fixedly connected to limit posts 13 to improve the stability of the movable rack 15 and movable rack 2 when sliding. The inner walls of the fixed slider 14 and fixed slider 2 are provided with limit grooves, and the side of the limit post 13 is slidably connected to the inner wall of the limit groove.

[0025] Furthermore, a controller 1 is fixedly connected to the inner wall at the top of the support platform 2, which facilitates the operation of the hydraulic lifting frame 3, the mobile vehicle 4 and the electric push rod 10 by the staff at height. The controller 1 is connected to the hydraulic lifting frame 3, the mobile vehicle 4 and the electric push rod 10 through the circuit wire.

[0026] Furthermore, a counterweight block 6 is fixedly connected to the bottom of the fixed tube 5, which increases the support stability and also improves the stability of the fixed tube 5 when the fixed tube 5 and the connecting rod 7 are separated. The bottom end of the connecting rod 7 is inserted through and movably connected to the top of the counterweight block 6.

[0027] Furthermore, a stepping platform 20 is fixedly connected to one side of the support platform 2, making it convenient for staff to climb onto the support platform 2 with their help.

[0028] Furthermore, a connecting plate 21 is fixedly connected to the bottom of the platform 20 to increase the stability of the platform 20 during use. One side of the bottom end of the connecting plate 21 is fixedly connected to the side of the mobile vehicle body 4.

[0029] Workers ascend the support platform 2 via stepping on platform 20, and then control the mobile vehicle 4 to move to the required work position via controller 1. During the movement of the mobile vehicle 4, the ends of the two inserts 19 and the active rack 9 furthest from the electric push rod 10 are respectively inserted into the locking grooves on both sides of the fixed pipe 5 and the reinforcing grooves on the side of the connecting rod 7. Upon reaching the required position, the electric push rod 10 is activated, causing the active rack 9 to retract away from the connecting rod 7. Simultaneously, the active rack 9 retracts away from the connecting rod 7, driving the gears 1 and 2 on both sides to rotate. This, in turn, causes the movable racks 2 17 and 15 to move closer to the connecting rod 7. Then, the movable racks 2 17 and 15 pull the two inserts 19 out of the locking grooves aligned on both sides of the connecting rod 7 and the fixed pipe 5. At this point, the active rack 9 moves away from the electric push rod 10. One end of the rod 0 is pulled out from the reinforcing groove aligned with the side of the fixed tube 5 and the connecting rod 7, thus the fixed tube 5 and the connecting rod 7 are designed separately. Then, the hydraulic lifting frame 3 is controlled to raise the rod. When the hydraulic lifting frame 3 is raised, the connecting rod 7 extends as the support platform 2 is raised. When the support platform 2 moves to the required working height, in order to improve the safety of the workers at height and the stability of the device, the electric push rod 10 is activated. The electric push rod 10 drives the active rack 9 to extend. The active rack 9 drives the movable rack 2 17 and movable rack 15 to approach the fixed tube 5 through the gear 1 8 and gear 2 18 respectively. The connecting rod 7 can be fixed by the insert 19 on the end of the active rack 9 away from the electric push rod 10 and the end of the movable rack 2 17 and movable rack 15. Thus, the two sides of the bottom of the support platform 2 can be supported by the fixed tube 5, the counterweight block 6 and the connecting rod 7.
