Description

Technical Field

[0001] This utility model relates to the field of maintenance ladder technology, specifically a maintenance ladder with anti-slip properties. Background Technology

[0002] Maintenance ladders provide a safe working platform, allowing maintenance personnel to easily access and handle various parts of buildings or equipment. Some maintenance work needs to be carried out at heights, and maintenance ladders provide a stable platform, enabling maintenance personnel to work safely. Since equipment in substations is often located at high positions, such as high-voltage switches, circuit breakers, and transformers, maintenance personnel need to perform regular inspections and maintenance. By using maintenance ladders, a safe working platform is provided for maintenance personnel, which can effectively reduce the risks of working at heights and prevent accidents such as falls.

[0003] The maintenance ladder provides a stable working platform, ensuring that maintenance personnel can easily reach the location requiring repair. It provides good working conditions for regular inspection and maintenance of substation equipment. When the maintenance ladder is in use, maintenance personnel need to rotate and open the two supports. Since the installation site of substation equipment is generally paved with gravel or grass, the ground is often uneven. When maintenance personnel climb the maintenance ladder, the center of gravity of the ladder is raised, and the two supports can rotate, which makes the supports of the maintenance ladder risky for side slippage. Therefore, we have proposed a maintenance ladder that can prevent side slippage. Utility Model Content

[0004] The purpose of this utility model is to provide a maintenance ladder that can prevent side slippage, in order to solve the problem mentioned in the background art that when maintenance personnel climb the maintenance ladder, the center of gravity of the maintenance ladder is raised and the two support ladders can rotate, which makes the support ladder of the maintenance ladder risking side slippage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a maintenance ladder with anti-slip capability, comprising support ladders and support plates, wherein two support ladders are movably connected to the support plates via a pivot, and a first mounting groove is provided on the side of the support plate near the support ladders, the first mounting groove being slidably connected to a connecting plate, and a first toothed plate is embedded on the lower side of the connecting plate, a slider is fixed on the upper side of the first toothed plate, a sliding groove is provided on the side of the support plate near the slider, and the slider is slidably connected to the sliding groove, and the first toothed plate is in contact with a second toothed plate.

[0006] Preferably, the support plate has a storage groove on the side near the second toothed plate, and the second toothed plate is slidably connected to the storage groove.

[0007] Preferably, the lower side of the second toothed plate is movably connected to the connecting rod via a bearing, and the upper end of the connecting rod is provided with a threaded groove.

[0008] Preferably, a fixing tube is sleeved on the outside of the threaded groove, and the fixing tube is fixed to the support plate.

[0009] Preferably, the first toothed plate and the second toothed plate are meshed together, and the cross-sectional dimensions of the slider match the cross-sectional dimensions of the groove.

[0010] Preferably, the second toothed plate matches the receiving groove, and the threaded groove is threadedly connected to the fixing tube.

[0011] Preferably, the lower end of the support ladder is provided with a second mounting groove, and the second mounting groove is movably connected to the bracket via a rotating shaft.

[0012] Preferably, a first magnetic block is fixed to one side of the bracket, and a second magnetic block is fixed to the inner side of the second mounting groove.

[0013] Preferably, the side of the second mounting groove closest to the second magnet is movably connected to one end of the screw via a rotating shaft, and the other end of the screw is connected to the connecting tube.

[0014] Preferably, the bracket has a slot on the side near the first magnet, and the connecting tube is connected to the slot.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This anti-slip maintenance ladder, by rotating the connecting rod, disengages the first toothed plate from the second toothed plate. At this time, the maintenance personnel can rotate and open the support ladder. After the support ladder is opened, the connecting rod is rotated in the opposite direction to engage the second toothed plate with the two first toothed plates, making it easier for the support ladder to maintain the angle of rotation and opening, making the maintenance ladder less prone to slippage. The bracket is moved out of the second mounting slot and puts it in contact with the ground. Then, the connecting pipe is rotated and the adjusting screw is rotated so that the connecting pipe can engage with the slot, keeping the bracket in contact with the ground. This provides auxiliary support for the maintenance ladder during use, thus preventing swaying.

[0016] 1. This anti-slip maintenance ladder provides a stable working platform, ensuring that maintenance personnel can easily reach the location requiring repair. It provides good working conditions for regular inspection and maintenance of substation equipment. When the maintenance ladder is in use, rotate the connecting rod to disengage the first toothed plate from the second toothed plate. At this time, the maintenance personnel can rotate to open the ladder. After the ladder is opened, rotate the connecting rod in the opposite direction to re-engage the second toothed plate with the two first toothed plates, making it easy for the ladder to maintain the rotation angle and making the maintenance ladder less prone to slipping.

[0017] 2. This anti-slip maintenance ladder, after being placed on the ground, pull the bracket to move it out of the second mounting slot and make it fit against the ground. Then rotate the connecting pipe and the adjusting screw to align the connecting pipe with the slot. Continue to rotate the connecting pipe so that it can engage with the slot, preventing the bracket from rotating and keeping the bracket in contact with the ground. This provides auxiliary support and prevents the maintenance ladder from swaying during use. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 and Figure 6This utility model provides a technical solution: a maintenance ladder with anti-slip capability, including a support ladder 1 and a support plate 101. Two support ladders 1 are movably connected to the support plate 101 via a pivot. A first mounting groove 2 is provided on the side of the support plate 101 near the support ladder 1. The first mounting groove 2 slidably engages with a connecting plate 201. A first toothed plate 202 is embedded in the lower side of the connecting plate 201. A slider 203 is fixed to the upper side of the first toothed plate 202. A sliding groove 204 is provided on the side of the support plate 101 near the slider 203, and the slider 203 slidably engages with the sliding groove 204. The first toothed plate 202 and a second toothed plate 205 are in contact with each other. A storage groove 206 is provided on one side near the second toothed plate 205, and the second toothed plate 205 slides and connects with the storage groove 206. The lower side of the second toothed plate 205 is movably connected to the connecting rod 207 through a bearing, and a threaded groove 208 is provided at the upper end of the connecting rod 207. A fixing tube 209 is sleeved on the outside of the threaded groove 208, and the fixing tube 209 is fixed to the support plate 101. The first toothed plate 202 and the second toothed plate 205 are meshed and connected. The cross-sectional dimensions of the slider 203 match the cross-sectional dimensions of the slide groove 204. The second toothed plate 205 matches the storage groove 206. The threaded groove 208 is threadedly connected to the fixing tube 209.

[0027] In specific implementation, according to Figures 1-4 and Figure 6 The maintenance ladder provides a stable working platform, ensuring that maintenance personnel can easily reach the location requiring repair. This provides excellent working conditions for regular inspections and maintenance of substation equipment. When the maintenance ladder is in use, rotating the connecting rod 207 causes the threaded groove 208 to rotate. The threaded groove 208 is threadedly connected to the fixed pipe 209, causing the connecting rod 207 to move the second toothed plate 205 downwards. The second toothed plate 205 matches the receiving groove 206, preventing it from rotating with the connecting rod 207 and making it less prone to rotational deviation during movement. This disengages the first toothed plate 202 from the second toothed plate 205, allowing maintenance personnel to rotate and open the support ladder 1. The support ladder 1 rotates to open to both sides, causing the connecting plate 201 to slide along the first mounting groove 2. The connecting plate 201 then causes the slider 203 to slide along the slide groove 204. The cross-sectional dimensions of the slider 203 match the cross-sectional dimensions of the slide groove 204, making it less prone to wobbling when the connecting plate 201 slides. This allows the two first toothed plates 202 to move stably in opposite directions. After the support ladder 1 is opened, the connecting rod 207 is rotated in the opposite direction, causing the connecting rod 207 to push the second toothed plate 205 upward. This allows the second toothed plate 205 to re-engage with the two first toothed plates 202, thus confining the second toothed plate 205 and the first toothed plates 202 together. This helps the support ladder 1 maintain its rotational opening angle and prevents the maintenance ladder from slipping sideways.

[0028] Please see Figure 1 , Figure 2 and Figure 5 The lower end of the support ladder 1 is provided with a second mounting groove 3, and the second mounting groove 3 is movably connected to the bracket 301 via a rotating shaft. A first magnetic block 302 is fixed on one side of the bracket 301, and a second magnetic block 303 is fixed on the inner side of the second mounting groove 3. The side of the second mounting groove 3 near the second magnetic block 303 is movably connected to one end of the screw 304 via a rotating shaft, and the other end of the screw 304 is connected to the connecting pipe 305. A slot 306 is provided on the side of the bracket 301 near the first magnetic block 302. The connecting pipe 305 is connected to the slot 306. The first magnetic block 302 and the second magnetic block 303 are magnetically attracted. The screw 304 is threadedly connected to the connecting pipe 305, and the connecting pipe 305 is engaged with the slot 306.

[0029] In specific implementation, according to Figure 1 , Figure 2 and Figure 5 After the maintenance ladder is placed on the ground, pull the bracket 301 to rotate the first magnetic block 302, causing the first magnetic block 302 to disengage from the second magnetic block 303. This allows the bracket 301 to move out of the second mounting slot 3 and fit against the ground. Then, rotate the connecting pipe 305, which is threadedly connected to the screw 304. This causes part of the connecting pipe 305 to move out of the screw 304. Rotate the adjusting screw 304 to align the connecting pipe 305 with the slot 306. Continue rotating the connecting pipe 305 to engage with the slot 306. This allows the screw 304 and the connecting pipe 305 to limit the bracket 301, preventing it from rotating and keeping it in contact with the ground. This provides auxiliary support for the maintenance ladder 1, preventing it from swaying during use.

[0030] In summary, the maintenance ladder provides a stable working platform, ensuring that maintenance personnel can easily reach the location requiring repair. This provides excellent working conditions for regular inspection and maintenance of substation equipment. When the maintenance ladder is in use, rotating the connecting rod 207 disengages the first toothed plate 202 from the second toothed plate 205, allowing the support ladder 1 to open. After opening, rotating the connecting rod 207 in the opposite direction re-engages the second toothed plate 205 with the two first toothed plates 202, making it easier for the support ladder 1 to maintain its open angle and preventing side slippage. This allows the bracket 301 to move out of the second mounting slot 3 and into contact with the ground. Then, rotating the connecting pipe 305 and the adjusting screw 304 allows the connecting pipe 305 to engage with the slot 306, providing auxiliary support for the support ladder 1 and preventing swaying during use.
