Description

Technical Field

[0001] This utility model relates to the field of ladder technology, specifically to a movable ladder that is easy to control. Background Technology

[0002] A ladder is an everyday tool consisting of two long, thick rods with a horizontal bar in the middle for climbing. Ladders are divided into single-step ladders and A-frame ladders.

[0003] Traditional ladders pose significant structural safety hazards in actual use. Specifically, after workers climb to the rooftop work surface, they need to manually drag the ladder to move laterally. Workers have to lift the ladder, which weighs tens of kilograms, with one hand. The misalignment between the ladder's weight and the direction of the force exerted by the worker creates a torque imbalance, which can easily lead to instability and falls. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: A controllable movable ladder includes a climbing mechanism and a sliding mechanism. The climbing mechanism includes two vertical shafts and multiple horizontal shafts detachably connected between the two vertical shafts. The sliding mechanism includes two sliders respectively connected to the two vertical shafts, a support rod slidably connected between the two sliders, two rollers movably connected to the bottom end of the support rod, two inserts slidably connected to the support rod, and two openings on the support rod suitable for the sliding of the inserts. Two insertion ports suitable for the outer ends of the inserts are opened on the inner side of the vertical shafts.

[0006] By adopting the above technical solution, when the operator moves the device horizontally on the roof, the insert on the support rod is connected to the lower insertion port away from the top of the vertical axis. Then, the two rollers at the bottom of the support rod contact the ground. By verticalizing the device, the operator can make the rollers reliably fit with the ground, and the vertical axis is simultaneously lifted off the ground and suspended in the air. The rolling characteristics of the rollers are used to achieve smooth movement of the device. This design, through the synergistic effect of mechanical self-locking and rolling mechanism, gives the high-altitude horizontal movement operation the technical advantages of high controllability and low force load.

[0007] In a preferred embodiment, the present invention can be further configured such that the cross-section of the slider is T-shaped, and both the slider and the support rod are made of carbon fiber material.

[0008] In a preferred embodiment, the present invention can be further configured such that the bottoms of the two rollers are located on the same horizontal plane, and the rollers are made of rubber material.

[0009] In a preferred embodiment, the present invention can be further configured such that two sockets are arranged vertically, and the depth of the sockets is equal to the length of the opening.

[0010] In a preferred embodiment, the present invention can be further configured such that a U-shaped rod is connected between the two vertical shafts, the U-shaped rod being close to the top of the support rod.

[0011] In a preferred embodiment, the present invention can be further configured as follows: multiple horizontal axes are equally spaced and arranged in a row, and each horizontal axis is provided with a locking assembly at both ends. The locking assembly includes a threaded rod screwed to the outer end of the horizontal axis, a baffle connected to the outer end of the threaded rod, and a lever plate installed on the outside of the baffle. The baffle is attached to the outside of the vertical axis.

[0012] In a preferred embodiment, the present invention can be further configured such that a rubber pad is fixedly connected to the bottom end of the vertical shaft, and the bottom area of ​​the rubber pad is equal to the bottom area of ​​the vertical shaft.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, when the operator moves the device horizontally on the roof, the insert on the support rod is connected to the lower insertion port away from the top of the vertical axis. Then, the two rollers at the bottom of the support rod contact the ground. By verticalizing the device, the operator can make the rollers reliably fit with the ground, and the vertical axis is simultaneously lifted off the ground and suspended in the air. The rolling characteristics of the rollers are used to achieve smooth movement of the device. This design, through the synergistic effect of mechanical self-locking and rolling mechanism, gives the high-altitude horizontal movement operation the technical advantages of high controllability and low force load.

[0014] 2. In this utility model, when the operator uses this device to climb to the roof working surface, the insert on the support rod and the plug at the top of the vertical shaft are inserted and locked. At this time, the roller connected to the support rod is raised above the rubber pad, giving the vertical shaft the condition to contact the ground. Then the operator tilts the vertical shaft and sets it up at the edge of the roof. Under the synergistic effect of the friction between the rubber pad and the roof contact surface, the overall slippage of the device is effectively prevented. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0018] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0019] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a movable ladder that is easy to control. Example

[0020] Combination Figure 1-5 As shown, the present invention provides a movable ladder that is easy to control, including a climbing mechanism 100 and a sliding mechanism 200. The climbing mechanism 100 includes two vertical shafts 110 and a plurality of horizontal shafts 120 detachably connected between the two vertical shafts 110. The sliding mechanism 200 includes two sliders 210 respectively connected to two vertical shafts 110, a support rod 220 slidably connected between the two sliders 210, two rollers 230 movably connected to the bottom end of the support rod 220, two inserts 240 slidably connected to the support rod 220, and two openings 250 formed on the support rod 220 and adapted for the sliding of the inserts 240. Two insertion ports 260 adapted for the outer ends of the inserts 240 are formed on the inner side of the vertical shaft 110.

[0021] Furthermore, the cross-section of the slider 210 is T-shaped, and both the slider 210 and the support rod 220 are made of carbon fiber. The shape design of the slider 210 makes it difficult for the support rod 220 to separate from the vertical axis 110. The fact that both are made of carbon fiber can reduce the overall weight of the device and make it easier for operators to control its displacement.

[0022] Furthermore, the bottoms of the two rollers 230 are located on the same horizontal plane. The rollers 230 are made of rubber material. The two rollers 230 made of rubber material cooperate with each other to make the instrument move horizontally stably and without generating noise.

[0023] Furthermore, the two sockets 260 are arranged vertically, and the depth of the sockets 260 is equal to the length of the opening 250. The two sockets 260 are provided to facilitate fixing the roller 230 in any state.

[0024] Furthermore, a rubber pad 500 is fixed to the bottom end of the vertical shaft 110. The bottom area of ​​the rubber pad 500 is equal to the bottom area of ​​the vertical shaft 110. The rubber pad 500 makes the vertical shaft 110 more stable when it is grounded. Example

[0025] Combination Figure 1-2 As shown, based on Embodiment 1, a U-shaped rod 300 is connected between the two vertical shafts 110. The U-shaped rod 300 is located near the top of the support rod 220. The U-shaped rod 300 can strengthen the connection between the two vertical shafts 110 and facilitate the operator to push the device laterally. Example

[0026] Combination Figure 1-2 As shown, in the above embodiment, multiple horizontal shafts 120 are arranged in a row with equal spacing. Each horizontal shaft 120 has a locking assembly 400 at both ends. The locking assembly 400 includes a threaded rod 401 screwed to the outer end of the horizontal shaft 120, a baffle 402 connected to the outer end of the threaded rod 401, and a lever 403 installed on the outside of the baffle 402. The baffle 402 is attached to the outside of the vertical shaft 110. When the locking assembly 400 is unscrewed, the horizontal shaft 120 is in a loose state, and the operator can replace the damaged horizontal shaft 120 accordingly.

[0027] The working principle and usage process of this utility model: When the operator uses this device to climb to the roof working surface, the insert 240 on the support rod 220 first completes the insertion and locking with the insertion port 260 at the top of the vertical shaft 110; at this time, the roller 230 connected to the support rod 220 is raised above the rubber pad 500, giving the vertical shaft 110 the condition to contact the ground. Then the operator tilts the vertical shaft 110 and sets it up at the edge of the roof. Under the synergistic effect of the friction between the rubber pad 500 and the roof contact surface, the overall slippage of the device is effectively prevented.

[0028] When lateral displacement of the roof is required, the operator shall follow the safety procedure below: pull out the insert 240 of the support rod 220. Under the action of gravity, the support rod 220 slides down the slider 210, and then the roller 230 contacts the ground; insert the insert 240 into the lower insertion port 260 away from the top of the vertical axis 110 to form a fixed structure; adjust the instrument to a vertical state through the U-shaped rod 300. At this time, the roller 230 reliably contacts the ground, and the vertical axis 110 is simultaneously lifted off the ground and suspended in the air; by controlling the lateral displacement of the U-shaped rod 300, the rolling characteristics of the roller 230 are used to achieve smooth movement of the instrument. This design, through the synergistic effect of mechanical self-locking and rolling mechanism, gives the high-altitude lateral displacement operation the technical advantages of high controllability and low force load.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
