A detachable wide foot buckle for electric power construction

Abstract

The present invention belongs to the technical field of wide foot buckles, and in particular relates to a detachable wide foot buckle for power construction, which comprises an arc-shaped buckle ring, a sliding support, a threaded sleeve, a mounting plate, an arc-shaped clamp, a fixing assembly, a foot sleeve, a first arc-shaped friction plate, a fixing strip, a limit block, a trigger pressure block, and a first spring. When a traditional foot buckle is used for a thicker electric pole, the distance between the arc segment of the arc-shaped buckle ring and the foot sleeve is relatively large. In the process of climbing the electric pole, the torque exerted on the foot sleeve by the arc segment of the arc-shaped buckle ring is also relatively large. If the worker works for a long time or on a higher electric pole, it often causes fatigue of the foot. The present invention designs two technical schemes. In the climbing process, when the worker lifts his foot to climb upward, the arc-shaped buckle ring on the corresponding side will be driven to slide relative to the sliding support, thereby reducing the torque exerted on the foot sleeve by the arc segment of the arc-shaped buckle ring; this has the effect of saving effort and relieving fatigue for the foot.

Description

Technical Field

[0001] The invention belongs to the technical field of wide foot buckles, and in particular relates to a detachable wide foot buckle for electric power construction. Background Art

[0002] Foot buckles are arc-shaped iron tools that are put on shoes and used to climb electric poles. Foot buckles mainly include cement pole foot buckles and wooden pole foot buckles, which are further divided into triangular tube foot buckles and round tube foot buckles. Wooden pole foot buckles are mainly used for climbing concrete poles or steel pipe towers of power and postal lines. Cement pole foot buckles are suitable for climbing cement poles of power and postal lines.

[0003] The foot buckle is generally made of high-strength seamless pipe. After heat treatment, it has the advantages of light weight, high strength, good toughness, good adjustability, lightness and flexibility, safety, reliability and easy to carry. It is an ideal tool for electricians to climb cement poles or wooden poles of different specifications.

[0004] The existing foot buckle has the following problems:

[0005] First, the existing foot buckle can be adjusted for different diameters of electric poles; for thicker electric poles, the required adjustment range is larger, so the torque acting in front of the sole of the foot is also relatively large. If working for a long time or on a higher electric pole, it often causes foot fatigue.

[0006] Secondly, during the climbing process, the construction workers' waist safety belts often break or the handheld objects fail to hold the electric poles. When this happens, if the construction workers do not stand firmly in time, they may fall down. However, since the construction workers' feet are still tied to the foot buckles at this time, the current foot buckles are easy to separate from the feet during the downward flipping process. When the foot buckles are separated from the feet, the construction workers may fall from the electric pole and get injured. Even if the foot buckles are not separated from the feet, the ankles may be sprained during the downward flipping process.

[0007] The present invention designs a detachable wide foot buckle for electric power construction to solve the above problems. Summary of the invention

[0019] 1. In the process of climbing a utility pole, when the worker climbs up the utility pole by clamping the foot buckle on the utility pole, that is, when the worker steps down to trigger the pressure block, the limit block can lock the mounting plate and the fixing strip. In this state, the foot cover, the mounting plate and the fixing strip become a whole, and the foot cover, the mounting plate and the fixing strip constitute the foot cover part of the traditional foot buckle; when the worker lifts his foot, the limit block will slide outward one section relative to the limit hole, but the arc surface area on the limit block is still in the limit hole. On the one hand, such a design is convenient for the limit block to be inserted into the limit hole again to limit the mounting plate and the fixing strip. At the same time, when the worker flips down, the limit block can also be smoothly detached from the limit hole under the action of the arc surface, and the foot buckle and the mounting plate that fix the worker's feet can flip with the worker, and there will be no ankle sprain.

[0020] 2. When traditional foot buckles are used for thicker electric poles, the distance between the arc segment of the arc buckle and the foot cover is relatively large. In the process of climbing the electric pole, the torque exerted on the foot cover by the arc segment of the arc buckle is also relatively large. If the worker works for a long time or on a higher electric pole, it often causes foot fatigue. The present invention designs two technical solutions. During the climbing process, when the worker lifts his foot to climb upward, the arc buckle on the corresponding side will be driven to slide relative to the sliding support, thereby reducing the torque exerted on the foot cover by the arc segment of the arc buckle; this saves effort and relieves fatigue for the feet.

DETAILED DESCRIPTION

[0042] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples or drawings are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0043] A detachable wide foot buckle for electric power construction, such as Figure 1 , 4 , 9, and 11, it includes an arc-shaped buckle ring 1, a sliding support 2, a threaded sleeve 4, a mounting plate 5, an arc-shaped clamp 6, a fixing assembly 7, a buckle belt 10, a foot cover 11, a first arc-shaped friction plate 12, a fixing strip 13, a limit block 14, a trigger pressure block 15, a first spring 20, a first rack 21, a third gear 22, a second rack 23, a second gear 24, a second spring 25, and a mounting shaft 26, wherein as Figure 4 As shown, a buckle 10 is installed on the upper side of the foot cover 11, and a mounting plate 5 is fixedly installed on the lower side of the foot cover 11; Figure 8 As shown, two first mounting grooves 17 are symmetrically formed on one side of the mounting plate 5, and a second mounting groove 18 communicating with the two first mounting grooves 17 is formed on the upper end surface of the mounting plate 5; Figure 7As shown, two limiting grooves 16 are symmetrically formed on one side of the fixing strip 13. Figure 4 , 5 As shown, the fixing strip 13 is mounted on one side of the mounting plate 5 by means of a ball joint; the trigger pressing block 15 is slidably mounted in the second mounting groove 18 opened on the mounting plate 5, and the upper end of the trigger pressing block 15 passes through the bottom panel of the foot cover 11 upward; Figure 5 , 9 As shown, a first spring 20 is installed between the trigger pressing block 15 and the mounting plate 5; two first racks 21 are symmetrically fixedly installed on the lower side of the trigger pressing block 15, and two mounting shafts 26 are symmetrically rotatably installed in the two first mounting grooves 17. A third gear 22 and a second gear 24 are fixedly installed on each mounting shaft 26, and the diameter of the third gear 22 is greater than the diameter of the second gear 24; Fig. 9 As shown, the two first racks 21 correspond to the two second gears 24 installed in the two first installation grooves 17 and mesh with each other; one end of the limit block 14 has an arc surface 19 symmetrically distributed up and down, as shown in FIG. Figure 5 As shown, the two limit blocks 14 are symmetrically slidably installed in the two first installation grooves 17, and the two limit blocks 14 correspond to the two limit holes opened on the fixing strip 13 one by one and cooperate with each other, and one end of the limit block 14 with the arc surface 19 faces the limit hole; Fig.10 As shown, a second rack 23 is slidably mounted on the other end of each limit block 14, and a second spring 25 is mounted between the second rack 23 and the limit block 14; Fig. 9 , 10 As shown, the two second racks 23 correspond to the two third gears 22 installed in the two first installation grooves 17 and mesh with each other; Figure 4 , 5 As shown, an arc-shaped clamp 6 is swingably mounted on the side of the fixing bar 13 facing away from the mounting plate 5 , and a first arc-shaped friction plate 12 is fixedly mounted on the arc-shaped clamp 6 .

[0044] In the present invention, the connection between the mounting plate 5 and the foot cover 11 can be achieved by welding or by bolting.

[0045] The first spring 20 has a reset effect on the trigger pressure block 15 .

[0046] In the present invention, the diameter of the third gear 22 is greater than the diameter of the second gear 24. The arrangement of the third gear 22 and the second gear 24 can ensure that when the trigger pressure block 15 is stepped on, the limit block 14 can have sufficient sliding stroke to enable the straight surface area that cooperates with the limit hole to completely slide out of the limit hole.

[0047] When the worker climbs up the pole by clamping the foot buckle on the pole, that is, when the worker steps on the triggering pressing block 15, the limiting block 14 can lock the mounting plate 5 and the fixing bar 13. In this state, the foot cover 11, the mounting plate 5 and the fixing bar 13 become a whole, and the foot cover 11, the mounting plate 5 and the fixing bar 13 constitute the foot cover 11 part of the traditional foot buckle; when the worker lifts his foot, the limiting block 14 will slide outward one section relative to the limiting hole, but the arc surface 19 area on the limiting block 14 is still in the limiting hole. On the one hand, such a design is convenient for the limiting block 14 to be inserted into the limiting hole again to limit the mounting plate 5 and the fixing bar 13; at the same time, when the worker flips down, the limiting block 14 can also be smoothly detached from the limiting hole under the action of the arc surface 19, and the foot buckle and the mounting plate 5 fixing the worker's foot can flip with the worker, and there will be no ankle sprain.

[0048] The installation method of the arc-shaped clamping member 6 and the first arc-shaped friction plate 12 on the fixing strip 13 in the present invention is completely the same as the installation method of the arc-shaped clamping member 6 on the foot cover 11 in the traditional foot buckle.

[0049] like Figure 2 As shown, a fixing assembly 7 is installed on the foot cover 11 and the mounting plate 5 .

[0050] like Figure 3 As shown, the fixing assembly 7 is composed of two annular fasteners 8 distributed up and down and four connecting parts 9 connecting the two annular fasteners 8 and connecting the lower annular fastener 8 with the foot cover 11 and the mounting plate 5.

[0051] The function of the fixing assembly 7 in the present invention is to fix the foot buckle, the mounting plate 5 and the structure mounted on the mounting plate 5 and the foot buckle to the legs of the worker; even if the worker falls down during the climbing process, the foot buckle will not separate from the worker, that is, the worker will not fall freely, which can protect the worker to a certain extent.

[0052] like Fig.11 , 16 As shown, a sliding support 2 is fixedly installed on one side of the fixing bar 13. Fig.15 , 19 As shown, the sliding support 2 is composed of a connecting rod 36 fixedly connected to the fixing bar 13 and a sliding sleeve 35 installed on the connecting rod 36.

[0053] like Fig.14 As shown, an arc-shaped buckle ring 1 is slidably mounted on the sliding sleeve 35 of the sliding support 2. The arc-shaped buckle ring 1 is divided into two sections, an arc-shaped section and a straight section. A second arc-shaped friction plate 28 is fixedly mounted on the arc-shaped section. An external thread 32 is provided on the outer circumferential surface of the straight section. The straight section is slidably mounted on the sliding sleeve 35. Fig.11 ,12 As shown, a third spring 30 is installed between the end of the straight section and the sliding sleeve 35, and the third spring 30 is a tension spring; a threaded sleeve 4 is installed on the straight section in threaded cooperation.

[0054] The third spring 30 serves to reset the arc-shaped buckle ring 1 .

[0055] The function of the threaded sleeve 4 is to limit the sliding of the arc-shaped buckle ring 1 relative to the sliding support 2. The position of the threaded sleeve 4 is adjusted according to the thickness of the electric pole. When the arc-shaped buckle ring 1 slides relative to the sliding support 2 under the action of the third spring 30 until the threaded sleeve 4 and the sliding support 2 are in contact and cooperate, the buckle structure composed of the arc segment of the arc-shaped buckle ring 1 and the arc-shaped clip 6 can be buckled on the electric pole for climbing.

[0056] Embodiment 1 of the arc-shaped buckle ring 1 sliding relative to the sliding support 2:

[0057] like Fig.14 As shown, the straight section of the arc-shaped buckle ring 1 has two strip grooves 31, and a third rack 33 is fixedly installed in each strip groove 31; Fig.15 As shown, four symmetrically distributed guide blocks 34 are fixedly mounted on the inner circumferential surface of the sliding sleeve 35 of the sliding support 2, and a notch 37 is opened on the outer circumferential surface of the sliding sleeve 35. Fig.13 As shown, the four guide blocks 34 are slidably matched with the two strip grooves 31; Fig.12 , 13 As shown, the first gear 3 is rotatably mounted on the sliding sleeve 35, and an annular groove is opened in the middle of the first gear 3. The teeth on the circular surfaces on both sides of the first gear 3 pass through the gap 37 and correspond to the two third racks 33 installed in the two strip grooves 31 one by one and mesh with each other; Fig.11 , 12 As shown, a pull rope 27 is wound in the annular groove in the middle of the first gear 3, and the outer end of the pull rope 27 extends upward.

[0058] Embodiment 2 of the arc-shaped buckle ring 1 sliding relative to the sliding support 2:

[0059] like Fig.18 As shown, a strip groove 31 is formed on the straight section of the arc-shaped buckle ring 1, and a third rack 33 is fixedly installed in the strip groove 31; Fig.19 As shown, two symmetrically distributed guide blocks 34 are fixedly mounted on the inner circumferential surface of the sliding sleeve 35 of the sliding support 2, and a notch 37 is opened on the inner circumferential surface of the sliding sleeve 35; Fig.13 As shown, the two guide blocks 34 are slidably matched with the strip groove 31; Fig.16 , 17 As shown in FIG. 18 , the fourth gear 39 is rotatably mounted on the sliding sleeve 35. Fig. 20As shown, the fourth gear 39 passes through the notch 37 and meshes with the third rack 33 ; the motor 38 is fixedly mounted on the sliding sleeve 35 , and the output shaft of the motor 38 is fixedly connected to the fourth gear 39 .

[0060] When the traditional foot buckle is used for thicker electric poles, the distance between the arc segment of the arc buckle ring 1 and the foot cover 11 is relatively large. In the process of climbing the electric pole, the torque exerted by the arc segment of the arc buckle ring 1 on the foot cover 11 is also relatively large. If working for a long time or on a higher electric pole, it often causes foot fatigue. In order to solve this problem, the present invention designs two different technical solutions.

[0061] With regard to the technical solution using the pull rope 27, during the process of the worker climbing up the electric pole, the worker manually pulls the pull rope 27 while lifting his foot, and the pull rope 27 pulls the first gear 3 to rotate, and the rotation of the first gear 3 drives the third rack 33 to slide, and the sliding of the third rack 33 drives the straight section of the arc-shaped buckle ring 1 to slide relative to the sliding support 2, so that the distance between the arc section of the arc-shaped buckle ring 1 and the foot cover 11 becomes shorter, reducing the torque of the arc section of the arc-shaped buckle ring 1 acting on the foot cover 11; thus, it saves effort and relieves fatigue for the feet.

[0062] With regard to the technical solution with the motor 38, during the process of the worker climbing up the electric pole, when the worker's foot is lifted, the motor 38 is controlled to work, the motor 38 drives the fourth gear 39 to rotate, the rotation of the fourth gear 39 drives the third rack 33 to slide, the sliding of the third rack 33 drives the straight section of the arc-shaped buckle ring 1 to slide relative to the sliding support 2, so that the distance between the arc-shaped segment of the arc-shaped buckle ring 1 and the foot cover 11 becomes shorter, and the torque of the arc-shaped segment of the arc-shaped buckle ring 1 acting on the foot cover 11 is reduced; it saves effort and relieves fatigue for the feet.

[0063] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.

[0064] Implementation method: When the foot buckle designed by the present invention is used, when the staff wears the foot buckle to climb the electric pole, when the staff steps on the foot cover 11, the staff's gravity will act on the trigger pressure block 15, and the trigger pressure block 15 will be forced to move downward relative to the mounting plate 5. The downward movement of the trigger pressure block 15 will drive the two first racks 21 to move downward, and the downward movement of the two first racks 21 will drive the two second gears 24 to rotate, and the rotation of the two second gears 24 will drive the two mounting shafts 26 to rotate, and the rotation of the two mounting shafts 26 will drive the two third gears 22 to rotate, and the rotation of the two third gears 22 will drive the two second racks 23 to slide, and the sliding of the two second racks 23 pushes the two limit blocks 14 to slide through the corresponding second springs 25, so that the end of the limit block 14 with the arc surface 19 is inserted into the two limit holes opened on the fixing bar 13, as shown in FIG. Figure 5 , 6 As shown, when the limit block 14 is fully matched with the limit hole, there is a straight surface area on the upper and lower wall surfaces of the limit block 14 with the arc surface 19 that matches with the limit hole. Through the cooperation of this part of the straight surface area and the limit hole, the swing between the fixing strip 13 and the mounting plate 5 is locked. When the staff member lifts his foot to climb, the pressure acting on the trigger pressure block 15 will disappear. At this time, under the action of the first spring 20, the trigger pressure block 15 will move up, and the trigger pressure block 15 will drive the limit block 14 to slide through the first rack 21, the third gear 22, the second gear 24 and the second rack 23, so that the straight surface area of ​​the limit block 14 that cooperates with the limit hole completely slides out of the outside of the limit hole. At this time, the arc surface 19 area on the limit block 14 is still in the limit hole and has not completely separated from the limit hole. At this time, the limit block 14 still has a locking function for the fixing bar 13 and the mounting plate 5, but the mounting plate 5 cannot be subjected to strong force; when the staff member steps down on the foot cover 11 again, the end of the limit block 14 with the arc surface 19 will be driven to slide completely into the limit hole again, and the straight surface area of ​​the limit block 14 that originally cooperated with the limit hole slides into the limit hole again and cooperates with the limit hole, locking the swing between the fixing bar 13 and the mounting plate 5.

[0065] During the climbing process, if the worker's waist safety belt breaks or the handheld object does not hold the electric pole and does not stand firmly in time, the worker may fall down. In this case, the pressure exerted by the worker on the trigger pressure block 15 will gradually decrease or disappear. At this time, the straight surface area of ​​the limit block 14 that cooperates with the limit hole completely slides out of the outside of the limit hole, but the arc surface 19 area on the limit block 14 is still in the limit hole and has not completely separated from the limit hole. At this time, the worker's downward flip will drive the mounting plate 5 to swing downward relative to the fixing bar 13 through the fixing assembly 7 and the foot cover 11, and the fixing plate drives the two limits to swing relative to the fixing bar 13. Under the action of the arc surface 19 on the limit block 14, the limit hole on the fixing bar 13 will squeeze the limit block 14, so that the limit block 14 slides relative to the second rack 23, and the second spring 25 is compressed; the end of the limit block 14 with the arc surface 19 is completely separated from the limit hole; at this time, the foot buckle and the mounting plate 5 that fix the worker's foot will flip together, and there will be no ankle sprain.
