Description

Technical Field

[0001] This invention relates to the field of insulated rigid ladder technology, and in particular to an insulated rigid ladder with an anti-slip structure. Background Technology

[0002] Insulated ladders are widely used as specialized climbing tools in power engineering, telecommunications engineering, electrical engineering, and hydropower engineering. The excellent insulation properties of insulated ladders maximize worker safety.

[0003] In practical use, insulated rigid ladders need to be tilted at multiple angles, but the steps of existing insulated rigid ladders cannot be quickly adjusted, resulting in poor structural integrity. Although existing devices can fix the ladder feet with ground nails, it is not convenient to remove the ground nails, which affects the efficiency of power construction. During use, existing devices cannot achieve auxiliary expansion, resulting in low adjustability.

[0004] In view of this, we have studied and improved the existing structure and its shortcomings, and provided an insulated rigid ladder with an anti-slip structure in order to achieve a more practical purpose. Summary of the Invention

[0005] The purpose of this invention is to provide an insulated rigid ladder with an anti-slip structure to solve the problems of existing insulated rigid ladders, which require multi-angle tilting during actual use and whose steps cannot be quickly adjusted, resulting in poor structural integrity; existing devices, although able to fix the ladder feet with ground nails, are not convenient to remove, affecting the efficiency of power construction; and existing devices cannot provide auxiliary expansion and have low adjustability during use.

[0006] To achieve the above objectives, the present invention provides an insulated rigid ladder with an anti-slip structure, specifically including a ladder body; a first stepping part is installed on the ladder body.

[0007] Furthermore, the first stepping part is composed of a pivot, a first pedal, a worm gear, a screw, and a first protrusion. Five first pedals are arranged in a linear array on the main body of the ladder. A pivot is fixed on the left and right end faces of each first pedal. The first pedal rotates on the main body of the ladder through the pivots on both sides. The first pedal is a rectangular plate structure. Each first pedal has a first protrusion welded in a linear array on its top surface. The first protrusion is a triangular prism structure.

[0008] Furthermore, a worm gear is fused to each of the rotating shafts on the left side, and a screw rotates on the left side of the ladder body, the screw meshing with five worm gears.

[0009] Furthermore, a second stepping part is installed on the first pedal. The second stepping part consists of a first connecting block, a second pedal, and a second protrusion. A first connecting block slides on each first pedal. The first connecting block contacts the first protrusion and is used to clean dirt from the first protrusion and the first pedal.

[0010] Furthermore, a second pedal is fused to the right end face of each of the first connecting blocks, and the second pedal is an extension of the first pedal.

[0011] Furthermore, each of the second pedals has a second protrusion welded in a linear array on its top surface. The second protrusion has a triangular prism structure, and the linear array of welded second protrusions is used for anti-slip of the second pedal.

[0012] Furthermore, the ladder body is equipped with a fixing part, which consists of a support block, ground nails and a second connecting block. There are two support blocks on the ladder body that rotate through a connecting shaft. Both support blocks are convex in shape, and two ground nails are inserted into each support block. All four ground nails are inserted into the soil.

[0013] Furthermore, the upper ends of the two ground nails on the left are each welded to a second connecting block, and the upper ends of the two ground nails on the right are each welded to another second connecting block. Both second connecting blocks are rectangular block structures, and the bottom surfaces of the two second connecting blocks are in contact with the top surfaces of the two support blocks, respectively.

[0014] Furthermore, a safety component is installed on the main body of the ladder. The safety component consists of a guide rod, a seat, a threaded rod, a second connecting rod, a clamping block, and an adjusting rod. Two guide rods slide on the main body of the ladder, and the rear ends of the two guide rods are fused to the seat. A threaded rod is threadedly connected to the main body of the ladder, and the rear end of the threaded rod rotates on the seat.

[0015] Furthermore, the seat body has a concave structure, and a second connecting rod is fused inside the threaded rod. Two clamping blocks slide on the second connecting rod. An adjusting rod rotates on the seat body, and one end of the adjusting rod on the left and one end on the right are threadedly connected to the two clamping blocks respectively. The thread directions of the left and right ends of the adjusting rod are opposite.

[0016] Furthermore, two first connecting rods are symmetrically welded to the top surface of the ladder body, and two slots matching the first connecting rods are symmetrically opened on the bottom surface of the ladder body.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this application, by setting up the second stepping part, on the one hand, when there is a lot of mud on the first protrusion and the top of the first step, the first connecting block can be slid left and right, and the mud on the first protrusion and the top of the first step can be cleaned by the scraping action of the first connecting block; on the other hand, when it is necessary to expand the stepping position to the right, the first connecting block can be slid to the rightmost position by hand. At this time, the second stepping plate is located on the right side of the ladder body, and people can step on the second stepping plate, thus realizing the expansion of the first step.

[0019] This application improves the fixing efficiency of four ground nails by simply striking the two second connecting blocks when fixing them; when removing the ground nails, a pry bar can be inserted into the gap between the support block and the second connecting block to pry them off, making removal convenient and quick.

[0020] In this application, by setting the first step part, the angle of the first step can be adjusted by simply rotating the screw. Driven by the worm screw, the five worm wheels rotate synchronously, thus realizing the angle adjustment of the first step. By adjusting, it can adapt to various tilt angles of the ladder body, which is highly flexible.

[0021] This application, through the setting of the safety part, on the one hand, when clamping and fixing with the utility pole by the clamping blocks, the two clamping blocks are placed on the left and right sides of the utility pole, and the adjusting rod is rotated. Under the adjustment of the adjusting rod, the two clamping blocks move inward to complete the clamping action; on the other hand, when adjusting the tilt angle of the ladder body after clamping, the threaded rod can be rotated. Under the drive of the threaded rod, the tilt adjustment of the ladder body can be realized, which has high adjustability.

[0022] In this application, by setting the first connecting rod, when multiple ladder bodies are spliced ​​together, the first connecting rod can be used in conjunction with the slot to achieve splicing, and the splicing makes it convenient to repair and maintain electrical equipment at higher positions.

[0023] In this application, by setting the first protrusion and the second protrusion, on the one hand, the first protrusion with its triangular prism structure can prevent the person's foot from slipping on the first pedal; on the other hand, when the worker steps on the second protrusion, it can prevent the foot from slipping, thus ensuring high safety.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Example 1:

[0042] like Figure 1 To be continued Figure 8 As shown:

[0043] The present invention provides an insulated rigid ladder with an anti-slip structure, comprising: a ladder body 1; and a first stepping part 2 installed on the ladder body 1.

[0044] The first stepping part 2 consists of a pivot 201, a first step 202, a worm gear 203, a screw 204, and a first protrusion 205. Five first steps 202 rotate in a linear array on the ladder body 1. A pivot 201 is fixed to the left and right ends of each first step 202. The first steps 202 rotate on the ladder body 1 through the pivots 201 on both sides. The first step 202 is a rectangular plate structure. The top surface of each first step 202 is fused with a first protrusion 205 in a linear array. The first protrusion 205 is a triangular prism structure. During use, the triangular prism structure of the first protrusion 205 can prevent the person's feet from slipping on the first step 202.

[0045] Each of the rotating shafts 201 on the left side is welded with a worm gear 203. A screw 204 rotates on the left side of the ladder body 1. The screw 204 meshes with the five worm gears 203. When adjusting the angle of the first step 202, simply rotate the screw 204. Driven by the screw 204, the five worm gears 203 rotate synchronously, thus achieving the angle adjustment of the first step 202.

[0046] The first pedal 202 is equipped with a second stepping part 3, which consists of a first connecting block 301, a second pedal 302, and a second protrusion 303. Each first pedal 202 has a first connecting block 301 sliding on it. The first connecting block 301 contacts the first protrusion 205. The first connecting block 301 is used to clean the dirt on the first protrusion 205 and the first pedal 202. When there is a lot of dirt on the first protrusion 205 and the top of the first pedal 202, the first connecting block 301 can be slid left and right. The dirt on the first protrusion 205 and the top of the first pedal 202 can be cleaned by the scraping action of the first connecting block 301.

[0047] Each first connecting block 301 has a second step pedal 302 welded to its right end face. The second step pedal 302 is an extension of the first step pedal 202. When it is necessary to extend the stepping position to the right, the first connecting block 301 is slid to the rightmost position by hand. At this time, the second step pedal 302 is located on the right side of the ladder body 1, and people can step on the second step pedal 302, thus realizing the extension of the first step pedal 202.

[0048] Each second pedal 302 has a second protrusion 303 welded in a linear array on its top surface. The second protrusion 303 is a triangular prism structure. The linear array of welded second protrusions 303 is used to prevent the second pedal 302 from slipping. When workers step on the second protrusions 303, their feet can be prevented from slipping.

[0049] The ladder body 1 is equipped with a fixed part 4, which consists of a support block 401, a ground nail 402, and a second connecting block 403. The ladder body 1 has two support blocks 401 that rotate through a connecting shaft. Both support blocks 401 are convex in shape. Each support block 401 has two ground nails 402 inserted into it, and all four ground nails 402 are inserted into the soil.

[0050] The two ground nails 402 on the left are each welded to a second connecting block 403 at one end, and the two ground nails 402 on the right are each welded to another second connecting block 403 at one end. Both second connecting blocks 403 are rectangular blocks, and their bottom surfaces contact the top surfaces of the two support blocks 401 respectively. When fixing the ground nails 402, the two second connecting blocks 403 can be directly struck, which improves the fixing efficiency of the four ground nails 402. When removing the ground nails 402, a pry bar can be inserted into the gap between the support block 401 and the second connecting block 403 to pry them off, making removal convenient and quick.

[0051] The ladder body 1 is equipped with a safety component 5, which consists of a guide rod 501, a seat 502, a threaded rod 503, a second connecting rod 504, a clamping block 505, and an adjusting rod 506. The ladder body 1 has two guide rods 501 that slide on it, and the rear end of each guide rod 501 is fused to the seat 502. The ladder body 1 is threaded with a threaded rod 503, and the rear end of the threaded rod 503 rotates on the seat 502.

[0052] The base 502 has a concave structure, and a second connecting rod 504 is fused inside the threaded rod 503. Two clamping blocks 505 slide on the second connecting rod 504. An adjusting rod 506 rotates on the base 502. The left and right ends of the adjusting rod 506 are threaded to the two clamping blocks 505 respectively. The threads of the left and right ends of the adjusting rod 506 are in opposite directions. When clamping and fixing the ladder body 1 with the clamping blocks 505, the two clamping blocks 505 are placed on the left and right sides of the ladder. The adjusting rod 506 is rotated, and the two clamping blocks 505 move inward to complete the clamping action. When adjusting the tilt angle of the ladder body 1 after clamping, the threaded rod 503 is rotated. The tilt adjustment of the ladder body 1 can be achieved under the drive of the threaded rod 503.

[0053] Example 2:

[0054] Based on Embodiment 1, it also includes: two first connecting rods 101 are symmetrically welded to the top surface of the ladder body 1, and two slots matching the first connecting rods 101 are symmetrically opened on the bottom surface of the ladder body 1. When multiple ladder bodies 1 are spliced ​​together, the first connecting rods 101 can be used to cooperate with the slots to achieve splicing.

[0055] The specific usage and function of this embodiment are as follows:

[0056] When fixing the ground nails 402, simply tap the two second connecting blocks 403, which improves the fixing efficiency of the four ground nails 402. When removing the ground nails 402, insert a pry bar into the gap between the support block 401 and the second connecting block 403 and pry it open. After the bottom of the ladder body 1 is fixed, place the ladder body 1 on the utility pole. Personnel step on the first step 202 to climb up and fix the top of the ladder body 1. When clamping and fixing it to the utility pole using the clamping blocks 505, place the two clamping blocks 505 on the left and right sides of the utility pole, rotate the adjusting rod 506, and the two clamping blocks 505 will move inward to complete the clamping action under the adjustment of the adjusting rod 506. When adjusting the tilt angle of the ladder body 1 after clamping, simply rotate the threaded rod 503. Driven by 03, the tilt adjustment of the ladder body 1 can be achieved; when adjusting the angle of the first step 202, simply rotate the screw 204. Driven by the worm screw 204, the five worm wheels 203 rotate synchronously, thus achieving the angle adjustment of the first step 202; when there is a lot of dirt on the first protrusion 205 and the top of the first step 202, slide the first connecting block 301 left and right. The scraping action of the first connecting block 301 can clean the dirt on the first protrusion 205 and the top of the first step 202; when it is necessary to extend the stepping position to the right, slide the first connecting block 301 to the rightmost position by hand. At this time, the second step 302 is located on the right side of the ladder body 1, and people can step on the second step 302, thus extending the first step 202.
