Description

Technical Field

[0001] This utility model discloses an electrical maintenance ladder, which belongs to the field of electrical maintenance. Background Technology

[0002] An electrical maintenance ladder is a ladder used for electrical maintenance and is insulated.

[0003] Existing power maintenance ladders often rely solely on attaching the ladder to the pole for work during utility pole repairs. However, power maintenance often requires applying force at height, which can cause the ladder to tip over due to the relative forces involved, leading to safety accidents.

[0004] A new solution is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical maintenance ladder in order to solve the above-mentioned problems.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: an electrical maintenance ladder, including a ladder body, two anti-tilting rods slidably disposed on the ladder body, a clamping head rotatably disposed on the anti-tilting rods, and a force-applying device for abutting the clamping head disposed inside the ladder body.

[0007] Preferably, the force-applying device includes a passive block fixed to the clamping head, an active block sliding inside the ladder body, and a spring abutting against the end of the active block away from the passive block. The contact surfaces of the passive block and the active block are both formed with inclined surfaces.

[0008] Preferably, the active block is provided with a guide protrusion for positioning the spring and passing through the spring, and a pull rope is fixedly connected to the guide protrusion, the pull rope extending to the end of the ladder body away from the anti-tilt bar.

[0009] Preferably, the ladder body has an opening at one end away from the ground for the pull rope to pass through, and the pull rope passes through the opening and is provided with an anti-detachment ring.

[0010] Preferably, the force-applying device includes a rotating head fixedly connected to the clamping head, a guide rod sleeved outside the rotating head and arranged along the length of the trapezoid, and a ratchet rotator for driving the guide rod to rotate.

[0011] Preferably, the ladder body is provided with a pawl for keeping the guide rod rotating in one direction, and the ladder body is provided with a pressing button that can separate the pawl from the guide rod.

[0012] Preferably, the guide rod is multi-segmented and can be nested into adjacent guide rods.

[0013] Preferably, the ladder body is configured in multiple sections.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This product extends the ladder body through the anti-tilt rod, so that the ladder body can pass through the utility pole from both sides through the anti-tilt rod during the erection. Then, the utility pole is clamped by the clamping head, and the clamping head is held in place by the force application device. This achieves a relatively fixed effect between the utility pole and the ladder body, so that the reaction force generated when the operator applies force is offset by the force application device, thereby making the ladder body more stable.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] like Figure 1 , Figure 2 As shown, a power maintenance ladder. Example 1:

[0021] The ladder includes a ladder body 1, on which two anti-tilt rods 2 are slidably mounted. A clamping head 3 is rotatably mounted on the anti-tilt rods 2. A force-applying device for abutting the clamping head 3 is provided inside the ladder body 1. The force-applying device includes a passive block 4 fixed on the clamping head 3, an active block 5 sliding inside the ladder body 1, and a spring 6 abutting the end of the active block 5 away from the passive block 4. The abutting surfaces of the passive block 4 and the active block 5 are both inclined. A guide protrusion for positioning the spring 6 and passing through the spring 6 is provided on the active block 5. A pull rope 7 is fixedly connected to the guide protrusion. The pull rope 7 extends to the end of the ladder body 1 away from the anti-tilt rods 2. An opening is provided at the end of the ladder body 1 away from the ground for the pull rope 7 to pass through. The pull rope 7 passes through the opening and is provided with an anti-detachment ring.

[0022] When using this product, first pull out the two anti-tilt rods 2 to the appropriate length, then pull the anti-detachment ring, which causes the anti-detachment ring to drive the pull rope 7, which in turn causes the pull rope 7 to drive the guide protrusion to slide along the length of the ladder body 1. At the same time, the spring 6 is compressed, causing the active block 5 to separate from the passive block 4. At this time, the passive block 4 loses its abutment, and the rotation restriction is canceled. At this time, simply place the ladder body 1 on the utility pole, and then release the anti-detachment ring. Under the action of the restoring force of the spring 6, the active block 5 is pushed by the spring 6, which causes the active block 5 to abut against the passive block 4. Due to the inclined surfaces on the active block 5 and the passive block 4, the inclined surfaces abut against each other, which causes the active block 5 to push the passive block 4 to rotate. When the passive block 4 rotates, it drives the clamping head 3, which clamps the utility pole. After the clamping head 3 has clamped the utility pole, the operator can use the ladder for maintenance. When it needs to be retrieved, simply pull the anti-detachment ring again to engage the clamping effect of the clamping head 3.

[0023] like Figure 3 As shown, Example 2:

[0024] The ladder includes a ladder body 1, on which two anti-tilt rods 2 are slidably mounted. A clamping head 3 is rotatably mounted on the anti-tilt rod 2. A force-applying device for abutting the clamping head 3 is provided inside the ladder body 1. The force-applying device includes a rotating head 8 fixedly connected to the clamping head 3, a guide rod 9 sleeved outside the rotating head 8 and arranged along the length of the ladder body 1, and a ratchet rotator 10 for driving the guide rod 9 to rotate. A pawl is provided on the ladder body 1 to keep the guide rod 9 rotating in one direction. A pressing button 11 is provided on the ladder body 1. The pressing button 11 can separate the pawl from the guide rod 9. The guide rod 9 is multi-segmented and can be inserted into adjacent guide rods 9.

[0025] To use this product, first pull out the anti-tilt bar 2, then place the ladder body 1 on the utility pole. At this point, adjust the force direction of the ratchet rotator 10, and then push the ratchet rotator 10 to make it drive the guide rod 9 to rotate. After the guide rod 9 rotates, it drives the rotating head 8 to rotate, which in turn drives the clamping head 3 to rotate. Due to the action of the pawl and the guide rod 9, the guide rod 9 can only rotate in one direction until it clamps the utility pole. After clamping, it can be used. After use, press the pressing button 11 to make the pressing button 11 separate the pawl from the guide rod 9. At the same time, adjust the direction of the ratchet rotator 10 so that the rotation of the guide rod 9 is no longer restricted. At this point, the clamping head 3 will no longer clamp the utility pole, allowing the operator to directly remove the ladder body 1. The guide rod 9 in this product is multi-segmented for convenient use during transportation.

[0026] The multi-section ladder body 1 makes this product more portable during use.
