[0032] like Figure 1 As shown, an embodiment of the utility model is a lifting device for inverted tank body plate strips, which is arranged on the tank top 90, and includes a connecting rod 10, a lifting device 20 and a walking device 30. The connecting rod 10 is arranged along the radial direction of the tank top 90, one end of which is rotatably connected to the tank top 90, and the other end extends out of the tank top 90. The lifting device 20 is arranged at the end of the connecting rod 10 extending out of the tank top 90, and is used for lifting the plate strips. The walking device 30 is arranged on the tank top 90, and the top of the walking device 30 is connected to the connecting rod 10, which can drive the end of the connecting rod 10 extending out of the tank top 90 to move along the circumferential direction of the tank top 90. The specific form of the lifting device 20 is not limited, as long as the plate strip can be lifted. In this embodiment, the lifting device 20 is specifically an electric hoist. The entire lifting device is installed on the tank top 90, and the walking device 30 drives the electric hoist to move circumferentially along the tank top 90. The plate belt hoisted on the electric hoist can be moved to any position of the tank body without moving the plate belt according to the installation position of the tank body. The continuous installation of the plate belt is realized, which saves the time of moving the entire lifting device and saves time and effort.

[0033] Specifically, a fixed shaft 40 is provided in the middle of the tank top 90, a rotating device 50 is provided on the fixed shaft 40, and one end of the connecting rod 10 close to the fixed shaft 40 is connected to the rotating device 50. In this embodiment, the fixed shaft 40 is vertically arranged, and the bottom of the fixed shaft 40 is fixedly connected to the tank top 90. The rotating device 50 is sleeved on the fixed shaft 40 and is rotatably connected to the fixed shaft 40. The tank top 90 is circular, and the connecting rod 10 is arranged along the radial direction of the tank top 90. One end of the connecting rod 10 extends out of the edge of the tank top 90 to facilitate the lifting of the plate belt, and the other end is connected to the rotating device 50.

[0034] Specifically, Figure 2 As shown, the rotating device 50 includes a bearing 51, which is sleeved on the fixed shaft 40 and connected to the end of the connecting rod 10 close to the fixed shaft 40. In this embodiment, the bearing 51 is sleeved on the fixed shaft 40, and the end of the connecting rod 10 close to the fixed shaft 40 is connected to the outer ring of the bearing 51, so that the end of the connecting rod 10 close to the fixed shaft 40 is rotatably connected to the fixed shaft 40.

[0035] Preferably, in order to prevent the bearing 51 from falling off due to axial movement of the fixed shaft 40, a bearing sleeve 52 is provided on the side of the bearing 51 away from the tank top 90. The bearing sleeve 52 is sleeved on the fixed shaft 40 and detachably connected to the fixed shaft 40 for axial positioning of the bearing 51. In this embodiment, a pin 53 is provided on the fixed shaft 40 for fixedly connecting the bearing sleeve 52 and the fixed shaft 40.

[0036] Preferably, in order to facilitate connection with the connecting rod 10, a bearing sleeve 54 is sleeved on the outside of the bearing 51 and fixedly connected to one end of the connecting rod 10 close to the fixed shaft 40. In this embodiment, the outer ring of the bearing 51 and the inner ring of the bearing sleeve 54 are transitionally matched, so that the bearing sleeve 54 can rotate around the fixed shaft 40. One end of the connecting rod 10 close to the fixed shaft 40 is fixedly connected to the outside of the bearing sleeve 54.

[0037] Preferably, Figure 1 As shown, since the tank top 90 is usually not a plane but an arch, in order to more conveniently install the connecting rod 10, a universal shaft 60 is provided at one end of the connecting rod 10 close to the fixed shaft 40. One end of the universal shaft 60 is fixedly connected to one end of the connecting rod 10 close to the fixed shaft 40, and the other end is fixedly connected to the outside of the bearing sleeve 54. In this embodiment, since the connecting rod 10 is a straight rod, the universal shaft 60 is provided to make the installation of the connecting rod 10 and the walking device 30 more flexible, and to prevent the connecting rod 10 from interfering with the arched tank top 90 when the connecting rod 10 moves along the circumferential direction of the tank top 90.

[0038] Preferably, a camera 70 is provided on the connecting rod 10, and the camera 70 is arranged near the walking device 30. By setting the camera 70, the running status and running track of the walking device 30 can be observed at all times, and transmitted to the cloud for remote monitoring. A control box 80 can be set on the tank top 90 to enable the operator to remotely monitor and control the walking device 30 on the ground. Remote control is a prior art and will not be described in detail here.

[0039] Specifically, Figure 3As shown, the walking device 30 includes a bracket 31, a driving wheel 32 and a driven wheel 33. The top of the bracket 31 is connected to the connecting rod 10. The driving wheel 32 and the driven wheel 33 are arranged at the bottom of the bracket 31. The driving wheel 32 is connected to the motor 35 through a belt 34, and the motor 35 is installed on the bracket 31. The driving wheel 32 can drive the entire walking device 30 to move along the circumferential direction of the tank top 90.

[0040] Preferably, in order to make the walking device 30 cooperate well with the tank top 90 and run stably during the lifting process. A shock absorbing device 36 is provided between the bracket 31 and the driving wheel 32 and the driven wheel 33. The specific form of the shock absorbing device 36 is not limited. In this embodiment, the shock absorbing device 36 is specifically a spring buffer, which is a prior art and is not described here. Two vertical spring buffers are symmetrically fixed at the bottom of the bracket 31, and the driving wheel 32 and the driven wheel 33 are respectively installed at the bottom of the spring buffer.

[0041] When in use, first install the entire device on the tank top 90. First determine the number of the plate to be installed, the position of the plate to be installed, and the installation position of the plate on the tank body. Start the walking device 30, so that the connecting rod 10 drives the lifting device 20 to move to the placement position of the hoisting plate, and the lifting device 20 lifts the plate to make it vertical to the ground. After the plate is stable, start the walking device 30, so that the lifting device 20 rotates along the shortest path around the tank top 90 to the installation position, and the lifting device 20 adjusts the height of the plate to the installation height, and then docks and installs the plate. After installation, install the next plate, and repeat the cycle.

[0042] The advantages and positive effects of the utility model are:

[0043] 1. During the installation process, there is no need to move the entire lifting device, which ensures the continuity of the plate and belt lifting and effectively improves the construction efficiency;

[0044] 2. Save the time and operation of disassembling and assembling the lifting device, save time and effort, and save construction costs;

[0045] 3. By setting a universal shaft, the installation of the connecting rod and the traveling device is more flexible;

[0046] 4. By setting up cameras, the walking mechanism can be monitored in real time to ensure the smooth progress of construction;

[0047] 5. The stability of the traveling mechanism is ensured by setting a shock absorbing device.

[0048] 6. Save construction costs, simple structure and convenient operation.
