Technical Field

[0001] This utility model relates to the technical field of power distribution equipment installation tools, specifically to a lifting mechanism based on a foot-operated hydraulic cylinder, which is suitable for the hoisting of electrical cabinets in space-constrained environments such as power distribution rooms. Background Technology

[0002] Traditional hoisting methods present several problems during the installation or replacement of electrical cabinets in power distribution rooms: Space constraints: Power distribution rooms have a compact layout with no pre-designed hoisting points at the top, and the cabinets are closely packed, making traditional hoisting equipment difficult to operate; Safety hazards: Relying on manual assistance to move heavy electrical cabinets poses a risk of injury, especially on uneven ground or in confined spaces; Low efficiency: Manual handling and adjustment of cabinet positions requires frequent tool and procedure changes, resulting in low work efficiency; Poor adaptability: Hoisting requirements for cabinets with varying heights, widths, and weights cannot be met by a single piece of equipment. While some existing hoisting equipment uses hydraulic systems, these are mostly electrically or manually pump-driven, making them inconvenient to use in environments without external power or with limited space. Therefore, there is an urgent need for a compact, flexible, and externally driven lifting mechanism to solve the problem of hoisting electrical cabinets in power distribution rooms. Utility Model Content

[0022] 1. Structural design of this utility model:

[0023] Mobile platform 2.1: It adopts a steel plate structure with bent ends, and achieves horizontal sliding by cooperating with the channel steel groove of the main frame 1.1 of the mobile trolley through the moving rollers 2.2;

[0024] Foot-operated hydraulic cylinder 2.3: As a power source, it is located at the rear end of the mobile platform 2.1 and drives the lifting sleeve II 2.5 to rise and fall along the column II 2.4 via a chain;

[0025] Column II2.4 and lifting sleeve II2.5: adopt a square tube nesting structure to ensure stability during the lifting process;

[0026] Horizontal boom 2.7: Fixed to the top of lifting sleeve II 2.5, extending to the outside of the moving trolley, used to suspend the electrical cabinet;

[0027] Movable lifting lug 2.8: can slide along the horizontal boom 2.7, and is linked with the horizontal push mechanism via a steel wire rope and a spiral push rod connected to the horizontal push frame 3;

[0028] Spiral sleeve 2.6: It works in conjunction with the spiral push rod on the horizontal push frame 3 to convert the horizontal rotational motion into linear motion, thereby achieving horizontal fine adjustment of the lifting mechanism.

[0029] Specifically:

[0030] The column II 2.4 is vertically welded to the rear end of the moving platform 2.1, and a foot-operated hydraulic cylinder 2.3 is installed, with its piston rod connected to the bottom of the lifting sleeve II 2.5 via a chain. A spiral sleeve 2.6 is welded to the upper part of the lifting sleeve II 2.5, ensuring that its axis is coaxial with the spiral push rod 3.8 of the horizontal push frame 3. The horizontal boom 2.7 is welded to the top of the lifting sleeve II 2.5, with one end extending to the outside of the moving trolley. A movable lifting lug 2.8 capable of moving left and right is installed on the outer edge of the horizontal boom 2.7, which is slidably connected by rollers 2.8.1. One end of each of the two wire ropes is connected to the positioning rod 3.9 of the horizontal push frame 3, and the other end of each wire rope passes over a reversing wheel 2.9 and is connected to the movable lifting lug 2.8.

[0031] 2. Working principle / process of this utility model:

[0032] Vertical lifting: The operator steps on the foot-operated hydraulic cylinder 2.3, which drives the lifting sleeve II 2.5 to rise or fall along the column II 2.4 via chain transmission, so that the hook connected to the movable lifting lug 2.8 can drive the vertical position adjustment of the electrical cabinet;

[0033] Horizontal movement: When the spiral push rod 3.8 on the horizontal push frame 3 rotates, the lifting mechanism moves horizontally as a whole through the spiral sleeve 2.6. Since the two moving rollers 2.2 are clamped in the channel steel grooves on the left and right sides of the main frame 1.1 of the moving trolley, the lifting mechanism can only move left and right. At the same time, the wire rope pulls the moving lug 2.8, so that it moves synchronously with the horizontal boom 2.7, and the moving distance is twice that of the lifting mechanism, which improves the flexibility of operation.

[0034] Collaborative operation: By cooperating with the foot-operated hydraulic cylinder 2.3 and the horizontal push frame 3, the position of the control electrical cabinet in three-dimensional space can be quickly realized, adapting to the compact installation environment of the power distribution room.

[0035] 3. Technical advantages of this utility model:

[0036] Manually powered: No external power supply required, suitable for working environments without power supply or explosion-proof requirements;

[0037] Compact structure: It adopts a nested square tube and folding design, which occupies little space and is suitable for operation in confined spaces;

[0038] Precise control: Horizontal fine-tuning is achieved through screw drive, combined with progressive lifting of foot-operated hydraulic cylinders to improve positioning accuracy;

[0039] Safe and reliable: Reduces direct human contact with heavy equipment and lowers operational risks.

[0040] Finally, it should be noted that this utility model is not limited to the above embodiments, and many variations are possible. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
