Description

Technical Field

[0001] This utility model relates to the field of ladder technology, and in particular to an insulated lifting ladder for building electrical construction. Background Technology

[0002] Building construction is a production activity carried out by people using various building materials and mechanical equipment according to specific design blueprints within a certain space and time to build various building products. During the building construction process, electrical construction is also carried out simultaneously, including the reservation and embedding of electrical conduits, electrical pipes, and junction boxes. Since it is necessary to climb heights during electrical construction, elevators are used. However, existing elevators come in various styles, and their stability is not good. They are prone to swaying during construction at heights, and their poor stability makes it inconvenient for the normal construction of electrical engineering. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose an insulated lifting ladder for building electrical construction.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An insulated lifting ladder for building electrical construction includes a main frame and casters. The casters are fixed to the bottom of the main frame. Both the front and rear ends of the main frame are laterally rotatably connected to bidirectional lead screws. Slider blocks are nested at the left and right ends of the outer sides of the bidirectional lead screws. The tops of the sliders are rotatably connected to support frames via shafts. Servo motors are fixed to the front and rear ends of the bottom right side of the main frame. A worktable is connected to the top of the support frame via shafts. The top of the worktable has an insulated guardrail and an insulating pad. A limit plate is vertically fixed to the outer side of the bottom of the worktable. An auxiliary box is fixed to the right side of the worktable. A hydraulic cylinder is vertically fixed to the lower part of the auxiliary box. A storage box is embedded inside the auxiliary box.

[0006] Preferably, the power output ends of the two servo motors are rotatably connected to a bidirectional lead screw via a belt, and a limit rod is horizontally embedded below the two sliders, with the sliders sliding left and right along the outer wall of the limit rod.

[0007] Preferably, a step is provided on the left side of the main frame, and the upper surfaces of the main frame and the auxiliary box are on the same horizontal plane as the top of the step. A hidden opening is provided inside the right side of the main frame, and the auxiliary box on the right side of the workbench is embedded in the hidden opening.

[0008] Preferably, the front and rear ends of the main frame are provided with limit openings, and the limit plate on the outer wall below the workbench is embedded in the limit opening. The cross-sectional area of ​​the limit opening is the same as the cross-sectional area of ​​the limit plate, and the limit plate moves up and down vertically in the limit opening.

[0009] Preferably, the top of the push rod at the output end of the hydraulic cylinder is connected to the bottom of the storage box, the outer wall of the storage box is in close contact with the inner wall of the auxiliary box, and the storage box moves vertically up and down in the auxiliary box.

[0010] Preferably, the storage box has 8-10 storage openings equidistantly arranged inside, and the inner walls of each storage opening are provided with protective pads.

[0011] 1. When two servo motors simultaneously drive the bidirectional lead screw to rotate in the slider, the sliders at the left and right ends of the bidirectional lead screw move simultaneously to one end in the middle of the bidirectional lead screw, pushing the worktable upward through the support frame. At this time, the limit rod can limit the slider to prevent the slider from tilting and misaligning, which would cause the worktable to shake during the lifting and lowering process. During the upward movement of the worktable, the bottom limit plate is always in close contact with the limit port of the main frame and slides in the limit port. The limit plate can effectively prevent the worktable from tilting unexpectedly after it is raised, resulting in high stability and greater ease of use.

[0012] 2. Before the workbench is raised or lowered, multiple tools that need to be used can be stored in the storage box inside the auxiliary box at the same time. This eliminates the need for workers to carry a large number of tools with them as the workbench rises, reducing the risk of tools accidentally falling off workers during the raising and lowering process. During the workers' work at height, the hydraulic cylinder lifts the storage box from inside the auxiliary box to a certain height, making it more convenient for workers to retrieve or replace the stored tools, and facilitating the normal construction of electrical engineering.

[0018] Main frame 1, casters 101, two-way lead screw 102, limit rod 103, slider 104, support frame 105, servo motor 106, worktable 2, insulated guardrail 201, insulated pad 202, limit plate 203, auxiliary box 204, hydraulic cylinder 205, storage box 206. Detailed Implementation

[0019] Example 1, referring to Figure 1-4 An insulated lifting ladder for building electrical construction includes a main frame 1 and casters 101. The casters 101 are fixed at the bottom of the main frame 1. The main frame 1 is characterized in that the front and rear ends of the lower part of the main frame 1 are rotatably connected to bidirectional lead screws 102. The left and right ends of the bidirectional lead screws 102 are nested with sliders 104. The top of the sliders 104 is rotatably connected to a support frame 105 through a shaft. The front and rear ends of the right side of the bottom of the main frame 1 are fixed with servo motors 106. The top of the support frame 105 is connected to a worktable 2 through a shaft. The top of the worktable 2 has an insulated guardrail 201 and an insulating pad 202. The bottom outer side of the worktable 2 is vertically fixed with a limit plate 203. The right side of the worktable 2 is fixed with an auxiliary box 204. The lower part of the auxiliary box 204 is vertically fixed with a hydraulic cylinder 205. The auxiliary box 204 has a storage box 206 embedded inside.

[0020] The power output ends of the two servo motors 106 are rotatably connected to the bidirectional lead screw 102 via belts. A limit rod 103 is horizontally embedded below the two sliders 104, and the sliders 104 slide left and right along the outer wall of the limit rod 103.

[0021] When the two servo motors 106 simultaneously drive the bidirectional lead screw 102 to rotate in the slider 104, the sliders 104 at the left and right ends of the bidirectional lead screw 102 move towards the middle end of the bidirectional lead screw 102 at the same time, and push the worktable 2 upward through the support frame 105. At this time, the limit rod 103 can limit the slider 104 to prevent the slider 104 from tilting and misaligning, causing the worktable 2 to shake during the lifting and lowering process.

[0022] A staircase is provided on the left side of the main frame 1. The upper surfaces of the main frame 1 and the auxiliary box 204 are on the same horizontal plane as the top of the staircase. A hidden opening is provided inside the right side of the main frame 1. The auxiliary box 204 on the right side of the workbench 2 is perfectly embedded in the hidden opening.

[0023] The front and rear ends of the main frame 1 are both open and have limit ports. The limit plate 203 on the outer wall below the worktable 2 is embedded in the limit port. The cross-sectional area of ​​the limit port is the same as the cross-sectional area of ​​the limit plate 203. The limit plate 203 moves up and down vertically in the limit port.

[0024] During the upward movement of the worktable 2, the bottom limiting plate 203 remains in close contact with the limiting port of the main frame 1 and slides within the limiting port. The limiting support of the limiting plate 203 effectively prevents the worktable 2 from tilting unexpectedly after it is raised, resulting in high stability and greater ease of use.

[0025] Example 2 differs from Example 1 in that, in this example, the top of the push rod at the output end of the hydraulic cylinder 205 is connected to the bottom of the storage box 206, the outer wall of the storage box 206 is in close contact with the inner wall of the auxiliary box 204, and the storage box 206 moves vertically up and down in the auxiliary box 204.

[0026] The storage box 206 has 8-10 storage openings evenly spaced inside, and the inner walls of the storage openings are all lined with protective pads.

[0027] Before the workbench 2 is raised or lowered, multiple tools that need to be used can be stored in the storage box 206 inside the auxiliary box 204 at the same time, so that the staff does not need to carry a large number of tools separately as the workbench 2 rises, reducing the risk of tools accidentally falling off the staff during the raising or lowering process;

[0028] During the construction process at height, the hydraulic cylinder 205 lifts the storage box 206 from the auxiliary box 204 to a certain height, making it more convenient for workers to retrieve or replace the stored tools and facilitating the normal construction of electrical engineering.

[0029] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
