Description

Technical Field

[0001] The utility model provides an engineering ladder for hydropower installation engineering, and relates to the technical field of engineering ladders. Background Art

[0002] As the name implies, the engineering ladder is a ladder used for engineering. Today's engineering ladders are no longer as monotonous as the single herringbone ladder (straight ladder) before. Its structure has gradually evolved towards adjustable height and variable shape, and it has become a ladder that is truly suitable for modern engineering. Now the water pipes and wires for decoration are buried in the wall, underground or ceiling. The water and electricity are decorated at the same time. Only after the water and electricity are finished can the water and electricity facilities required to be installed on the floor and walls of the room be decorated. The whole process must use the engineering ladder as an auxiliary tool; with the acceleration of urbanization, in the era of electricity, many people's homes are connected to tap water, and water and electricity installation has become an important part of home decoration. The water and electricity installation project accounts for about 1 / 4 of the entire decoration project task.

[0003] Usually, various tools are often used in water and electricity installation, but the function of the engineering ladder is relatively simple and lacks space to accommodate tools and materials. After climbing up the engineering ladder, workers need to carry and use various types of tools. However, they cannot carry too many or too heavy tools on the engineering ladder at one time, otherwise the stability of the engineering ladder will be affected due to overweight. Another person is required to cooperate with the person on the engineering ladder to manually transfer the tools, or the workers can get down from the engineering ladder to get the tools and then return to the engineering ladder. Sometimes, decoration materials are needed and they need to get them when they are used. The round trip is easy to waste working time and reduce work efficiency. Utility Model Content

[0021] The maximum turning angle between the long reference member 23 and the ladder 1 is ninety degrees. The upper and lower sides of the front end of the ladder 1 are respectively installed with a latch 2 9 and a latch 1 4. The middle part of the long reference member 23 is threadedly connected with a screw 17. The middle part of the lower end of the support platform 13 is fixed with a support block 18 rotatably connected between the screws 17. The outer end of the screw 17 is transmission-connected with a motor 10 installed under the frame 11. A slide bar 19 is slidably connected between the two long reference members 23 and at both ends of the screw 17. The left and right ends of the slide bar 19 are fixed to the lower end of the frame 11.

[0022] Before the construction of hydropower installation project, according to Figure 1 and Figure 2As shown, the engineering ladder is placed on the ground at the construction site of the hydropower installation project. The motor 10 can be powered by a battery. The distance between the two ladders 1 is adjusted according to the stability of the ground at the construction site of the hydropower installation project. The motor 10 drives the corresponding screw 17 to rotate around the support block 18. The long reference member 23 moves left and right along the lower end of the long reference member 23 as the screw 17 rotates. The long reference member 23 slides left and right along the surface of the slide bar 19. The ladder 1 and the corresponding long reference member 23 are located in a vertical plane. The upper end of the latch 29 is inserted from the ladder 1 to the surface of the corresponding long reference member 23. The latch 29 limits the upper end of the ladder 1. Flip along the lower end of the corresponding long reference piece 23, the second latch 9 is used to keep the ladder 1 and the corresponding long reference piece 23 in a vertical line. The long reference piece 23 keeps the two ladders 1 connected to the corresponding bottom of the box 11. The two ladders 1 move left and right as the long reference piece 23 moves left and right. At the same time, it is convenient for the motor 10 to drive the screw 17 to adjust the spacing between the two long reference pieces 23 under the box 11. Changing the spacing between the two ladders 1 can change the position of the two bottom plates 2 stacked on each other, thereby changing the contact area between the bottom plate 2 and the ground, so that the engineering ladder can be placed on the ground with different flatness and inclination.

[0023] In the process of adjusting the distance between the two ladders 1, the tilting rod 8 pulls the weight 6 as the distance between the two ladders 1 changes, and the screw rod 7 passes through the left and right sides of the weight 6. The screw rod 7 is rotated on the left and right sides of the weight 6. The two screw rods 7 are spirally rotated inside the weight 6 until the tail ends of the screw rods 7 are tightly attached to the corresponding surface of the ladder 1. The screw rod 7 and the tilting rod 8 are used together to form a triangular structure between the two ladders 1, thereby limiting the mutual movement between the two ladders 1 and keeping the two ladders 1 stable.

[0024] The maximum flipping angle between the bottom plate 2 and the ladder 1 is ninety degrees. The two bottom plates 2 are stacked on each other. A long cavity 3 is opened in the middle of the bottom plate 2. The two bottom plates 2 allow the corresponding two long cavities 3 to be stacked and aligned with each other. The bottom plate 2 is flipped to an angle perpendicular to the ladder 1. The lower end of the latch 4 is inserted into the bottom plate 2. The latch 4 limits the bottom plate 2 from flipping along the bottom of the ladder 1. Bolts 5 are provided inside the long cavity 3. The bolts 5 are screwed into the long cavity 3. The outer surface of the bolt 5 is inserted into a matching nut. The nut is tightly attached to the surface of the bottom plate 2. The nut keeps the two stacked bottom plates 2 in close contact. The bolt 5 fastens the two bottom plates 2, the latch 1 4, the long cavity 3 and the bolt 5 are used together to keep the bottom plate 2 and the ladder 1 in a vertical angle. The ladder 1, the bottom plate 2, the frame 11 and the long reference piece 23 are used together to form a structure surrounded by a counterweight 6. The bottom plate 2, the long cavity 3, the latch 1 4, the screw 7 and the tilting rod 8 play the role of stably placing the counterweight 6 between the two ladders 1. The latch 1 4, the weight 6, the screw 7, the tilting rod 8, the frame 11 and the long reference piece 23 are used together to reinforce the two ladders 1 and ensure that the ladder 1 is stably placed.

[0025] The ladder 1 is arranged in a pair to form a platform for stably supporting the frame 11. The frame 11 forms a reference surface for the support platform 13 to form a stable support. Connecting columns 12 are fixed at the four corners between the support platform 13 and the frame 11. The connecting columns 12 keep the frame 11 and the support platform 13 firmly connected. The notch 14 is located between the connecting columns 12. Notches 14 are provided at the left and right ends of the support platform 13 to facilitate workers to climb from the ladder 1 to the support platform 13 to carry out construction work. The support platform 13 provides a working platform for the workers. The rear end of the wire wheel 22 is transmission-connected with the motor 21. The motor 21 is fixed behind the accommodating seat 16. The accommodating box 15 provides a supporting platform for the wire wheel 22 and the motor 21. The rope is wound inside 22, and the motor 21 and the wire wheel 22 use the receiving seat 16 as the support point. The motor 21 can be powered by a battery. The motor 21 drives the wire wheel 22 to rotate to unwind or reel the rope. The wire wheel 22 unwinds the rope to lower the hook to the ground, and the wire wheel 22 reels the rope to hoist the tools and materials onto the support platform 13. A hook is tied to the end of the rope to hoist the tools and materials on the ground into the receiving box 15, and the receiving seat 16 provides a space for the receiving box 15 to accommodate and place. The receiving box 15 is convenient for storing the tools and materials required for construction, and there is no need to go back and forth between the engineering ladder and the ground, which saves time, speeds up the progress, and improves efficiency.

[0026] When the construction task of the hydropower installation project is completed, the bolt 5 is screwed out from the inside of the long cavity 3, and the latch 1 4 is pulled up to make the lower end of the latch 1 4 detach from the corresponding upper end of the bottom plate 2, and the two bottom plates 2 are respectively turned inward along the corresponding lower ends of the ladder 1, and the bottom plate 2 and the ladder 1 are stacked and kept parallel to achieve the effect of folding the bottom plate 2 and the ladder 1, and the latch 2 9 is pulled down to make the upper end of the latch 2 9 detach from the outer surface of the corresponding long reference member 23, and the upper end of the ladder 1 uses the corresponding long reference member 23 as the reference surface to achieve the effect of folding with the bottom of the frame 11, and the front end of the frame 11 is installed with a lock buckle 3 20, and the lock buckle 3 20 reinforces the folded ladder 1 and the bottom plate 2, so that the ladder 1 can be folded and stored, so as to be taken to the next hydropower installation project construction site for use;

[0027] Hydropower installation projects require the simultaneous construction and layout of infrastructure in terms of waterways and circuits. Construction sites often change. Since the engineering ladder can be folded and extended, it is suitable for use in situations where construction sites often change, and plays a role in promoting the progress of hydropower installation project construction.
