Detailed Description of the Specific Embodiments
[0027] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanations of this utility model. Unless otherwise specified, all technical and scientific terms used in this utility model have the same meanings as those commonly understood by those of ordinary skill in the technical field to which this utility model belongs.
[0028] Embodiment 1
[0029] In this embodiment, a composite ladder for an outlet in an integrated pipe gallery proposed by this utility model is mainly used in an integrated pipe gallery, such as Figure 1As shown in the figure, the integrated pipe gallery includes a first steel platform 1, a second steel platform 9, a first main pipe 10 inside the gallery, a second main pipe 11 inside the gallery, a third main pipe 12 inside the gallery, and a power cabin 13.
[0030] In a typical embodiment of the present utility model, as Figures 1-3 shown, a composite ladder for the outlet in the integrated pipe gallery is provided, which includes a fixed support vertical ladder 2. A chute 3 is provided on the fixed support vertical ladder 2. One end of the chute 3 is slidably connected to one end of a sliding inclined ladder 4. The other end of the sliding inclined ladder 4 is provided with a universal wheel 7; a folding handrail 5 is provided on the sliding inclined ladder 4.
[0031] In this embodiment, the top end of the sliding inclined ladder 4 is slidably connected to the chute 3 provided on the upper part of the fixed support vertical ladder, so that the sliding inclined ladder 4 can slide up and down in the chute 3 of the fixed support vertical ladder. At the same time, the other end of the sliding inclined ladder 4 is not connected to the fixed support vertical ladder and is provided with a universal wheel 7. It can be understood that when the top end of the sliding inclined ladder 4 slides in the chute 3 of the fixed support vertical ladder, the other end thereof moves away from the fixed support vertical ladder under the action of the universal wheel 7, and the sliding inclined ladder 4 and the lower part of the fixed support vertical ladder open a certain distance.
[0032] Specifically, the ladder beam of the fixed support vertical ladder is made of 60mm×10mm flat steel, the tread bar is made of round steel with a diameter of 20mm, and the chute 3 is made of round steel with a diameter of 30mm. The steel materials used for the structure are all Q235B and are treated with hot-dip galvanized anti-corrosion. Except for special instructions, the connections between different components are all fixed by welding to ensure that the overall structure of the composite ladder has sufficient bearing capacity. In other embodiments, the materials and dimensions can be selected according to the actual situation.
[0033] The top end of the fixed support vertical ladder is fixedly connected to the first steel platform 1, and the bottom end of the fixed support vertical ladder is fixedly connected to the pipe gallery floor 8. In this embodiment, the fixed support vertical ladder is perpendicularly and fixedly connected to the first steel platform 1 and the pipe gallery floor 8 respectively, which can play a better supporting role for the steel platform and ensure its stability.
[0034] The length of the chute 3 is less than the length of the fixed support vertical ladder. In this embodiment, the chute 3 can be welded to the upper part of the ladder beams on both sides of the fixed support vertical ladder by welding. When the end of the sliding inclined ladder 4 connected to the chute 3 descends to the lowest position of the chute 3, the lower part of the sliding inclined ladder 4 opens a certain angle relative to the fixed support vertical ladder. However, due to the limited working space in the integrated pipe gallery, to prevent the sliding inclined ladder 4 from interfering with other structures in the pipe gallery, the length of the chute 3 is set to be less than the length of the fixed support vertical ladder to prevent the lower part of the sliding inclined ladder 4 from opening too large an angle.
[0035] In addition, one end of the sliding chute 3 close to the first steel platform 1 is an open structure, and the other end of the sliding chute 3 is a closed structure. In this embodiment, the top of the sliding chute 3 is an open structure, and the bottom is a sealed structure. This setting facilitates the staff to take out the sliding inclined ladder 4 through the open structure at the upper part of the sliding chute 3 and then move it to other positions with temporary requirements, and cooperate with other fixed support vertical ladders to realize the flexible movement of the climbing ladder.
[0036] The universal wheels 7 roll on the pipe gallery floor 8. In this embodiment, there are two universal wheels 7, which are symmetrically arranged at the two side beams of the sliding inclined ladder 4 respectively. When the top end of the sliding inclined ladder 4 slides in the sliding chute 3, the other end abuts against the pipe gallery floor 8, providing a flexible movement function for the whole sliding process and also enabling stable support.
[0037] One end of the sliding inclined ladder 4 is provided with a buckle structure, and the buckle structure is slidably connected to the sliding chute 3. In this embodiment, buckle structures are provided on the two side beams at the top end of the sliding inclined ladder 4, and the buckle structures are slidably connected to the sliding chute 3. The sliding inclined ladder 4 forms a semi-rigid connection with the sliding chute 3 of the fixed support vertical ladder through the top buckle, realizing vertical movement and horizontal limit.
[0038] One end of the sliding inclined ladder 4 is connected to the safety lock 6, and the other end of the safety lock 6 is connected to the fixed support vertical ladder. In this embodiment, the safety lock 6 is arranged at the lower part of the sliding inclined ladder 4 and the fixed support vertical ladder. The safety lock 6 includes a chain, and the connection positions of the two ends of the chain to the sliding inclined ladder 4 and the fixed support vertical ladder are on the same horizontal plane. Through the safety lock 6, stable support at different angles of the sliding inclined ladder 4 can be realized.
[0039] There are multiple folding handrails 5, which are symmetrically hinged to the two side beams of the sliding inclined ladder 4 respectively. The folding handrails 5 on the two side beams fold inwards relatively, and the folding angle is 90°. The height of the folding handrail 5 is less than half of the distance between the two side beams of the sliding inclined ladder 4. In this embodiment, a safety handrail that can be folded at 90° is arranged on the side beam of the sliding inclined ladder 4 to improve the comfort and safety of the inclined ladder, facilitate the staff to climb while carrying tools. The clear distance between the side beams is 500mm, the distance between the treads is 300mm. The side beams of the sliding inclined ladder 4 are made of 45mm round steel, and the treads and the top buckles are both made of 20mm round steel. In addition, the size of the folding handrail 5 is considered for anti-pinching design. The height of the folding handrail 5 is less than half of the distance between the two side beams of the sliding inclined ladder 4. When the folding handrails 5 fold inwards relatively, a certain distance can be maintained between the opposing handrails to prevent pinching, and the folding handrails 5 do not overlap with the treads when folding.
[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
