Description

Technical Field

[0001] This utility model belongs to the field of power engineering technology, and in particular relates to a power engineering emergency repair ladder. Background Technology

[0002] Electricity is an energy source that uses electrical energy as its power source. However, due to various unforeseen factors, power supply systems often experience power outages. Therefore, power maintenance personnel are needed to carry out emergency repairs on power lines. Power repair ladders are the most commonly used auxiliary tools in the process of power repair, which can help repair personnel repair or inspect elevated power lines. However, currently, when using repair ladders, one worker needs to work on the ladder while another worker holds it from below, which is not conducive to saving manpower.

[0003] Chinese utility model patent CN220791110U discloses a power engineering emergency repair ladder, comprising a secondary ladder that is snapped onto one side of a primary ladder. A slider for fixing is fixedly connected to one side of the primary ladder, and a sliding groove for fixing is provided on one side of the secondary ladder. An insulating plate for protection is snapped onto the bottom of the primary ladder, and an anti-slip pad for protection is fixedly connected to the lower surface of the insulating plate. This power engineering emergency repair ladder, through the setting of the insulating plate and anti-slip pad, ensures that the bottom of the repair ladder is snapped onto the inner wall of the insulating plate, so that the sliding of the bottom of the repair ladder is synchronized with the insulating plate during use. The anti-slip pad, fixedly connected to the lower surface of the insulating plate, prevents the insulating plate from easily sliding on the ground, thus achieving the purpose of preventing the bottom of the repair ladder from easily sliding. Therefore, no worker is needed to hold the bottom of the repair ladder during use, which helps save manpower.

[0004] However, the above-mentioned device has the following technical problems in actual use:

[0005] 1. The above-mentioned device directly inserts the bottom end of the first step ladder into the slot opened in the insulating plate to fix the first step ladder. However, only a small part of the bottom end of the first step ladder is inserted into the slot. Furthermore, since the above-mentioned device lacks a locking and limiting device for the bottom end of the first step ladder inside the insulating plate, the first step ladder may still separate from the insulating plate when the operator operates the ladder too much during actual use, posing a risk of workers falling.

[0006] Second, although the above-mentioned device is equipped with a second-level ladder to increase the overall height of the ladder, in some usage scenarios, the ladder may still not be able to reach the specified height after it is fully extended. The above-mentioned device also lacks expansion capability, which affects actual use. Utility Model Content

[0007] This utility model provides a power engineering emergency repair ladder, which aims to solve the problem mentioned in the background art that the above-mentioned device lacks a limiting device for the bottom of the first ladder inside the insulation plate. This causes the device to shake if the manual operation is too large, resulting in the separation between the first ladder and the insulation plate. In addition, the above-mentioned device lacks expansion capability and cannot adjust the length of the ladder according to the actual use, which affects the actual use.

[0008] This utility model is implemented as follows: a power engineering emergency repair ladder includes a base on which a ladder body is detachably and fixedly connected. The ladder body comprises multiple ladder segments sequentially spliced ​​along the longitudinal direction, and each ladder segment has two symmetrically arranged vertical ladder frames. Multiple ladder treads are evenly spaced between the two ladder frames, and these treads are distributed longitudinally. Each pair of adjacent ladder segments is detachably connected by connecting structures located at the top and bottom of the two ladder frames. The base also has corresponding openings at the bottom of the two ladder frames. The slots are provided, and each slot has a locking mechanism movably connected to the base on both sides. The locking mechanism is used to clamp the ladder frame inserted into the slot from both sides. In this solution, the main body of the ladder is composed of multiple ladder bodies spliced ​​together in sequence. In actual use, the operator can select an appropriate number of ladder bodies according to the actual operating height and splice them together in sequence through the connecting structure. Then, the bottom end of the spliced ​​ladder body is inserted into two slots. This method can meet the construction requirements of workers for different operating heights and is not limited by the extension length of the ladder.

[0009] In addition, when the bottom of the ladder body is inserted into the slots on both sides, the rotating rod rotates and drives the two opposite threaded sections on it to rotate. The rotation of each opposite threaded section will drive the two moving plates on it to move closer to each other, and at the same time drive the two side clamping blocks to move into the slots. The clamping blocks clamp and fit against the two sides of the ladder frame, limiting the placement of the ladder frame and ensuring that the ladder frame is placed vertically. This prevents the ladder frame from shaking, tilting, or separating from the base during subsequent use.

[0010] Preferably, the two ends of the ladder plate abut against the side walls of the ladder frame on both sides, and each end of the ladder plate has a receiving groove. A fixing block is fixedly installed on the side wall of the ladder frame corresponding to the receiving groove. The fixing block is inserted into the receiving groove. A fastening bolt is inserted from the top of the ladder plate, passes through the receiving groove and the fixing block in sequence, and then exits from the bottom of the ladder plate. A fastening nut is threaded onto the threaded end of the fastening bolt. In this scheme, when assembling the ladder plate, the ladder plate is placed between the two ladder frames. Then, the fixing blocks on the side walls of the two ladder frames are inserted into the receiving grooves on the side walls of the two ladder frames. Next, the threaded section of the fastening bolt is inserted from the insertion hole at the top of the ladder plate, passes through the receiving groove and the fixing block, and then exits from the insertion hole at the bottom. A fastening nut is screwed onto the threaded section of the fastening bolt to fix and limit its movement, preventing the ladder frame and the ladder plate from separating and ensuring normal use in the future.

[0011] It should be noted that this method allows staff to quickly replace damaged ladder boards without replacing the entire set of equipment, greatly reducing maintenance costs.

[0012] Preferably, the connection structure includes: a first groove at the bottom of the ladder frame, a connecting column slidably connected within the first groove, and a second groove at the top of the ladder frame for accommodating the connecting column. The first groove has corresponding first locking holes on its inner walls on both sides, and a second locking hole is also provided on the inner wall of the first groove below the first locking hole. The connecting column has a first through hole and a second through hole corresponding to the first and second locking holes on its side walls. The second groove has corresponding third locking holes on its inner walls on both sides. A first screw rod penetrating the first through hole is provided in the first locking hole, and a second screw rod penetrating the second through hole is provided in the second locking hole. Locking nuts are threaded to the ends of both the first and second screw rods. In this solution, when adjacent... When assembling two ladder bodies, first place one ladder body on top of the other. Then, operate on the ladder body on top, remove the first and second screws at the bottom of the two ladder frames. After the connecting column is unrestrained, part of its bottom end will protrude from the first slot. Insert the protruding part into the second slot opened at the top of the ladder frame (of the lower ladder body), so that: the first through hole and the second locking hole are aligned, and the second through hole and the third locking hole are aligned. Then, insert the first screw from one side of the second locking hole, pass through the first through hole, and then pass out from the second locking hole on the other side. Screw a locking nut on the part that passes out. At the same time, insert the second screw from one side of the third locking hole, pass through the second through hole, and then pass out from the third locking hole on the other side. Screw a locking nut on the part that passes out. This allows for quick assembly between two adjacent ladder bodies.

[0013] Preferably, guide grooves are vertically formed on the inner walls of the other two sides of the first groove, and guide blocks are slidably connected in the guide grooves. The guide blocks are fixedly installed on the two side walls of the connecting column. In this solution, by setting guide grooves and guide blocks, the connecting column can be prevented from detaching from the first groove. On the other hand, it can also ensure that when the connecting column moves, the first through hole is aligned with the second locking holes on both sides, and the second through hole of the protruding part is aligned with the third locking holes on both sides.

[0014] Preferably, the locking mechanism includes: movable cavities disposed at the bottom of the two slots, a rotating rod rotatably connected within each movable cavity, and interconnected drive grooves on both sides of each slot, each drive groove containing a retaining block, the bottom of each retaining block communicating with the movable cavity via a moving groove, a bidirectional threaded section on the outer wall of the rotating rod at the bottom of each slot, the two opposite threaded sections of the bidirectional threaded section being aligned with the two moving grooves respectively, and a moving plate slidably connected within each moving groove, the bottom end of the moving plate being threadedly connected to the bidirectional threaded section, and... The top end and the clamping block are fixed to the side wall away from the slot. In this scheme, when the rotating rod rotates, it will drive the two sets of bidirectional threaded segments on its outer wall to rotate. Each slot bottom is provided with a set of bidirectional threaded segments, and the two opposite threaded segments in each bidirectional threaded segment are respectively provided on both sides of the slot. When the rotating rod rotates, it will drive the two moving plates screwed on each bidirectional threaded segment to move towards each other in the moving groove. At the same time, the moving plates will drive the clamping block fixed on its top wall to move towards the slot. Finally, the clamping block extends into the slot to fit against the surface of the ladder frame, limiting and clamping the ladder frame.

[0015] Preferably, both ends of the rotating rod extend to the outside of the base and are fixedly connected to a rotating disk; in this design, the rotating disk makes it easier for workers to grip and thus better drive the rotating rod to rotate.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides an emergency repair ladder for power engineering.

[0017] 1. The main body of the ladder in this device is composed of multiple ladder bodies spliced ​​together in sequence. In actual use, the operator can select an appropriate number of ladder bodies according to the actual operating height and splice them together in sequence through the connecting structure. Then, the bottom end of the spliced ​​ladder body is inserted into two slots. This method can meet the construction requirements of workers for different operating heights and is not limited by the extension length of the ladder.

[0018] 2. In this device, after the bottom end of the ladder body is inserted into the slots on both sides, the rotating rod rotates and drives the two opposite threaded sections on it to rotate. The rotation of each opposite threaded section will drive the two moving plates on it to move closer to each other, and at the same time drive the two side clamping blocks to move into the slots. The clamping blocks clamp and fit against the two sides of the ladder frame, limiting the placement of the ladder frame and ensuring that the ladder frame is placed vertically, preventing the ladder frame from shaking, tilting, or separating from the base during subsequent use.
