Description

Technical Field

[0001] This utility model relates to a device for raising equipment, and in particular to a step-by-step raising and lifting device for raising large equipment. Background Technology

[0002] When large urban infrastructure such as elevated bridges needs to be dismantled, fixed-height lifting structures made of square steel are used for on-site assembly to fill the gaps in the dismantled bridge parts. However, due to the varying heights of elevated bridges, the lifting structures often fail to fit properly on-site, necessitating the fabrication of lifting structures of different sizes. This type of lifting device can only perform a one-time lifting operation, the height cannot be precisely calculated and controlled, and extensive dismantling is required after use, resulting in long construction periods and high costs. Currently, there are also shim devices used for the dismantling or installation of large equipment. However, these devices only have corresponding shim block conveying platforms, lacking a dedicated centralized shim block preparation platform. Therefore, forklifts and other transport tools must be used to directly place individual shim blocks onto the conveying platform for transport. This means only one shim block can be transported at a time. If there are many shim blocks, multiple trips are required to transport all the blocks, wasting significant manpower and resources and greatly reducing the efficiency of the shim work. Utility Model Content

[0003] This invention provides a step-by-step lifting device for raising large equipment, which can not only save manpower and material resources, but also greatly improve the efficiency of lifting.

The control system includes a main controller. The lifting system mainly includes a base, with lifting cylinders for raising blocks installed around the upper part of the base. A lifting platform for raising blocks is installed on the top of the lifting cylinders, and the bottom of the lifting cylinders is installed on the upper part of the base. A displacement sensor I is installed on the lifting piston rod I of the lifting cylinder, which monitors the vertical movement of the piston rod I. The signal output terminal of the displacement sensor I is connected to the input port I of the main controller. The control port I of the main controller is connected to the control port of the lifting cylinder. A lifting area for raising blocks is set between the upper part of the base and the lifting platform, corresponding to the lifting block inlet / outlet in the middle of the lifting platform. The upper surface of the base is the placement area for raising blocks. Lifting block locking devices are installed around the lifting platform, with each locking device locking a block located within the lifting platform. The locking slots on the sides of the raised blocks that need to be moved correspond to the positions of the blocks. The material preparation system is located outside the lifting system. The material preparation system includes a receiving platform, a left-side material preparation lifting device, and a right-side material preparation lifting device. The bottoms of the left-side and right-side material preparation lifting devices are located at both ends of the receiving platform. Limiting blocks are also provided on both sides of the receiving platform, and the limiting blocks correspond to the limiting slots on the bottom of the raised blocks. The automatic feeding platform is installed on the upper part of the receiving platform and in the raised block placement area. Several raised blocks are stacked from top to bottom on the left-side material preparation lifting device. In the material preparation area of ​​the raised block between the device and the right-side material preparation lifting device, the left-side and right-side material preparation lifting devices can separate the upper raised block from the bottom raised block located on the automatic feeding platform. The bottom raised block is transported to the raised block placement area by the automatic feeding platform. The lifting platform is moved to the position corresponding to the locking groove on the side of the raised block by the raised block locking device through the raised block lifting cylinder, and locked in the raised block lifting platform. The raised block lifting platform is driven to move up and down by the raised block lifting cylinder, thereby moving the raised block.

[0005] Furthermore, the left and right material preparation lifting devices of this utility model are symmetrically distributed. The left material preparation lifting device includes a left limiting support frame, with a left base located at the bottom inner side of the left limiting support frame.

A right base is provided at the bottom of the inner side of the right limit support frame. A right lifting cylinder is vertically installed in the middle of the right base. A right crossbeam is horizontally installed on the right lifting cylinder. The right locking device is installed on the right crossbeam.

The right lifting cylinder can push the right crossbeam to move up and down on the right linear guide rail. At the same time, the right crossbeam drives the right locking device to move up and down. The shim block preparation area is located between the left limit support frame and the right limit support frame. When it is necessary to transport the bottom shim blocks, the left and right locking devices lock the second-to-last shim blocks that need to be locked. The left and right lifting cylinders drive the left and right crossbeams to rise, respectively, causing the second-to-last and above shim blocks that need to be lifted to be aligned with the bottom shim blocks located on the automatic feeding platform.

The right guide sleeve moves inward. When it is necessary to lift the shim block, the two left locking blocks on the left side extend into the left limiting groove of the second-to-last shim block under the action of the left push cylinder, and the two right locking blocks on the right side extend into the right limiting groove of the second-to-last shim block under the action of the right push cylinder, thereby locking the position of the second-to-last shim block. Displacement sensors III are installed on both the left and right locking blocks. The displacement sensor III installed on the left locking block is used to monitor the movement status of the left locking block, and the displacement sensor III installed on the right locking block is used to monitor the movement status of the right locking block.

The screw slider drives the track wheel of the pallet base to slide horizontally back and forth on the tracks installed on the receiving platform and in the raised block placement area. The movement of the pallet base also drives the raised block conveying pallet to move horizontally back and forth. Position sensor I and position sensor II are respectively installed on the two bearing seats. Position sensor I is used to monitor the positioning of the raised block conveying pallet when it moves on the track section of the delivery platform, and position sensor II is used to monitor the positioning of the raised block conveying pallet when it moves on the track section of the raised block placement area. Position sensor I and position sensor II are both connected to the input port IV of the main controller.

A position sensor IV is installed on the telescopic piston rod IV. The position sensor IV is used to monitor the extension and retraction position of the telescopic piston rod IV. All position sensors IV are connected to the input port VI of the main controller. The input port VI of the main controller is connected to the control port of the pin telescopic cylinder.

[0009] Furthermore, the main controller described in this utility model is configured as a PLC controller.

[0010] This utility model has the following beneficial effects: By adopting the above technical solution, this utility model includes a material preparation system. This system can automatically and cyclically separate and transport multiple raised blocks after preparation, eliminating the need for manual operation. This not only achieves a high degree of automation but also allows for the control of multiple execution devices through the control system. This enables simultaneous preparation of multiple raised blocks, followed by automatic material discharge, feeding, and lifting. A single forklift can load multiple devices within a single work cycle, significantly improving the efficiency of material preparation and feeding. This allows for rapid completion of the lifting operation, saving manpower and resources, and greatly increasing the efficiency of the lifting operation. This utility model uses a servo motor to drive the raised block conveyor tray to transport the raised blocks. Because it can effectively and precisely control the speed and position, the servo motor controls the ball screw to precisely control the positioning of the raised block conveyor tray during transmission. This ensures that the raised blocks on the conveyor tray accurately reach the lifting position, thereby improving the accuracy and efficiency of the lifting process. The present invention features a pin telescopic cylinder that pushes the pin body into the pin groove on the side of the shim block. Since the piston rod and the pin body are connected by a transverse support shaft, the transverse support shaft has both supporting and rotating functions, thus supporting the shim block more stably and distributing the force more evenly, ensuring safety during the lifting and lowering of the shim block. Moreover, the piston rod and the pin body are rotatably connected, allowing the pin body to be rotated to adjust the support angle during the lifting or lowering of the shim block, thereby achieving a better support effect.

[0023] exist Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6In this invention, the usage process is as follows: First, six stacked support blocks 12 are transported by a forklift to the bottom receiving platform 10 of the support block preparation area between the left limiting support frame 55 and the right limiting support frame 18. When the displacement sensor II 23 detects that the left lifting piston rod II 24 and the right lifting piston rod II 25 have moved to the designated position, the displacement sensor II 23 sends the detected position signal to the PLC controller. The PLC controller controls the left lifting cylinder 15 to drive the left crossbeam 16 and the right lifting cylinder 20 to drive the right crossbeam 21 to the position of the second to last layer of support blocks 12 in the stacked support blocks 12. Then, the PLC controller controls the left pushing cylinder 26 to push the left locking block 27 and the right pushing cylinder 30 to push the right locking block 28. 9 are inserted into the left and right limiting slots on both sides of the second-to-last layer of raised blocks 12 to lock the position of the second-to-last layer of raised blocks. Then, the left lifting cylinder 15 and the right lifting cylinder 20 are driven to raise the left locking block 27 and the right locking block 29 respectively, thereby causing the second-to-last and above raised blocks 12 to move upward, causing the bottom raised block 12 on the receiving platform 10 to separate from the other raised blocks 12. At this time, the bottom raised block 12 is pushed upward by the lifting cylinder 46 and disengages from the limiting blocks on both sides of the receiving platform 10. Then, the servo motor 36 drives the raised block conveying tray 33 with the bottom raised block 12 to move and send the bottom raised block 12 into the raised block placement area 9, completing the placement of the first raised block 12. During the feeding process, the PLC controller controls four lifting cylinders 46 to lift the first shim block 12, so that the locking groove on the side of the shim block 12 corresponds to the pin body 50 on the shim block lifting platform 4. The PLC controller controls the pin extension cylinder 49 to drive the pin body 50 to insert into the locking groove to lock the position of the first shim block 12. Finally, the PLC controller controls the shim block lifting cylinder 49 to move upward, and the shim block lifting platform 4 moves the first shim block 12 upward. After the position sensor II 45 detects the position of the shim block conveying tray 33, it sends the position signal of the shim block conveying tray 33 to the PLC controller. The PLC controller controls the servo motor 36 to rotate in the opposite direction, and the shim block conveying tray 33 moves upward. Driven by the servo motor 36, the next raised block 12 is transported back to the receiving platform 10. After the raised block transport tray 33 is in place on the receiving platform 10, the position sensor I 44 detects the position of the raised block transport tray 33 and controls the servo motor 36 to stop working through the PLC controller. At this time, the PLC controller, based on the position signals of the left lifting piston rod II 24 and the right lifting piston rod II 25 detected by the displacement sensor II 23, controls the left lifting piston rod II 24 and the right lifting piston rod II 25 to drive the remaining raised blocks 12 down to the returned raised block transport tray 33. Then, the above operation steps are used to send the second to last raised block 12 to the raised block placement area 9, thus completing the transport of the second raised block 12.Displacement sensor I6 detects the position of lifting piston rod I5 and sends a signal to the PLC controller. The PLC controller lowers the lifting platform 4 of the shim block to the position of the second shim block 12 via the lifting piston rod I5. At this time, the PLC controller also controls the left locking block 27 and right locking block 29 to retract from their locking slots based on the position signals detected by displacement sensor III31. Then, it controls the left locking block 27 and right locking block 29 to lock the position of the second shim block 12 and moves the second shim block 12 upward via the lifting platform 4. At this time, the second shim block 12 can lift the first shim block 12. This process is repeated to complete the transportation and lifting of the remaining shims, thereby enabling the lifting operation of large equipment installation and transportation as needed.

[0024] However, this is not the only possibility. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope defined in the claims.
