Abstract
Description
Technical Field
[0001] This invention relates to the field of electromechanical installation technology, specifically to an electromechanical installation lifting drive structure and lifting method. Background Technology
[0002] The installation of equipment, lines, and pipelines in general industrial and public / civilian construction projects, substation projects of 35 kV and below, and the fabrication and installation of non-standard steel components all fall under the category of electromechanical installation. This includes the installation of boilers, ventilation and air conditioning systems, refrigeration systems, electrical systems, instrumentation systems, motors, compressor units, and broadcasting and television control equipment. Currently, for equipment installed at higher locations, elevators are often used. Most existing elevators use steel cables and pulleys to lift the equipment; however, because the lifting height is related to the equipment's height, the overall size of the equipment is relatively large, occupying a significant portion of the space. The space required is large and difficult to access. Therefore, patent application number CN202010250344.3 specifically describes a remote-controlled electromechanical installation lifting system and lifting drive structure. The structure uses a cylinder, hydraulic cylinder or lead screw to drive the piston rod to move horizontally, which in turn drives the drive arm to swing and lift the lifting component. At the same time as the lifting component is lifted, the piston rod also drives two sets of translation components to move horizontally in opposite directions under the action of the meshing structure, which in turn drives the extension component to extend into the worktable. The support arm drives the telescopic component and the box installed at the end of the telescopic component to be further lifted along the through groove opened on the lifting component, which has a two-way lifting function.
[0003] However, the aforementioned patent application CN202010250344.3 utilizes gear and rack meshing for locking, which is less prone to falling and has higher safety compared to steel cable hoisting. However, since the meshing between the gear and rack lacks a self-locking function, the gear and rack may rotate, making the locking function unstable. In addition, although the device occupies little space, it requires manual handling when moving. Furthermore, because the device is made entirely of metal, it is relatively heavy, making manual handling laborious and time-consuming. Summary of the Invention
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this invention provides an electromechanical installation lifting drive structure and lifting method, which solves the problem that the lack of a self-locking function between the gear and rack may cause the gear and rack to rotate, resulting in unstable locking function. In addition, although the device occupies little space, it requires manual handling when moving, and because the device is made of metal, it is relatively heavy, making manual handling laborious and time-consuming.

[0041] This invention provides a technical solution: a method for lifting and driving electromechanical installation, comprising the following steps;
[0042] S1. Lifting / Lowering: Activate the first hydraulic cylinder 3 within the inner cavity of the first mounting base 2, causing the telescopic end of the first hydraulic cylinder 3 to push the drive arm 14 to move. The drive arm 14 then drives the support arm 4 to rotate upwards on the surface of the rotating component 12. Next, activate the third hydraulic cylinder 15, causing the telescopic end of the third hydraulic cylinder 15 to extend the first telescopic arm 5 within the inner cavity of the support arm 4, thereby lifting / lowering the placement box 6.
[0043] S2. Self-locking: When the first telescopic arm 5 is raised, it drives the sleeve arm 111 and the second telescopic arm 113 to rotate in the first connecting seat 112 and the second connecting seat 114 respectively, and causes the second telescopic arm 113 to slide out of the inner cavity of the sleeve arm 111. When the third hydraulic cylinder 15 drives the first telescopic arm 5 to the highest point, the limiting block 118 in the inner cavity of its groove 1111 moves to the position of the through groove 1113, and under the elastic force of the spring 1112, it drives the limiting block 118 to insert into the inner cavity of the through groove 1113, so that the second telescopic arm 113 and the sleeve arm 111 complete self-locking. When unlocking is required, the second hydraulic cylinder 1110 is first activated, so that the telescopic end of the second hydraulic cylinder 1110 passes through the connecting... The connecting block 117 drives the sliding block 116 to slide in the inner cavity of the slide groove 115 and presses the limiting block 118, causing the limiting block 118 to retract into the inner cavity of the groove 1111, so that the arc surface of the limiting block 118 is located in the inner cavity of the through groove 1113. Then, the third hydraulic cylinder 15 drives the first telescopic arm 5 to descend, causing the first telescopic arm 5 to push the second telescopic arm 113 to retract in the sleeve arm 111, so that the arc surface of the limiting block 118 presses the through groove 1113, causing it to retract completely into the inner cavity of the limiting block 118, releasing the rotational self-lock between the sleeve arm 111 and the second telescopic arm 113, so that the first telescopic arm 5 completes its descent, and the first hydraulic cylinder 3 drives the drive arm 14 to retract, so that the support arm 4 can be reset.
[0044] S2. Handling: After use, insert the buckle 10 into the slot 13 to secure the restraint strap 9 to the support arm 4. Then, lift the base plate 1 with the handle 18 so that the roller 8 contacts the ground and the support foot 7 leaves the ground.
