In some embodiments, referring to fig. 1, a grappler anti-slip and anti-slip device 100, the grappler anti-slip and anti-slip device 100 comprises: support mechanism 10, tread mechanism 20 and cleat assembly 30. The support mechanism 10 includes a connecting member 12 and an outer frame 11, and the tread mechanism 20 includes an inner frame 22 and a tread assembly 21 disposed on the inner frame 22. The inner frame 22 and the outer frame 11 are connected to the connecting member 12 at a parallel interval, and a clasping space 40 is formed between the tread assembly 21 and the outer frame 11. The anti-slip assembly 30 includes a first anti-slip pad 31, a first protrusion set 32, a second anti-slip pad 33, and a second protrusion set 34, wherein the first anti-slip pad 31 and the first protrusion set 32 are disposed at intervals on a side of the outer frame 11 facing the hugging space 40, and the second anti-slip pad 33 and the second protrusion set 34 are disposed at intervals on a side of the tread assembly 21 facing the hugging space 40. Wherein, the first protrusion set 32 and the second protrusion set 34 each comprise a plurality of anti-slip protrusions 35 spaced apart from each other.

In the above-mentioned anti-slip and anti-drop device 100 for a climber, the anti-slip and anti-drop device 100 for a climber can be held tightly on a telegraph pole through the holding space 40 during climbing operation on the telegraph pole. Because the outer frame 11 is provided with the first anti-slip pad 31 and the first bulge group 32 at intervals, the pedal assembly 21 is provided with the second anti-slip pad 33 and the second bulge group 34 at intervals, both sides of the telegraph pole are subjected to the action of the anti-slip pad and the bulge group without grabbing the structure, the grabbing stability is improved, the probability of slipping and falling during climbing operation in rainy season or moist environment is effectively reduced, and the operation safety is improved.

It should be noted that, the enclasping space 40 is formed between the tread assembly 21 and the outer frame 11, so that during climbing, the telegraph pole can be clamped between the tread assembly 21 and the outer frame 11, so that the outer frame 11 and the tread assembly 21 are respectively attached to the telegraph pole, thereby facilitating stable climbing. The tread assembly 21 is a structure that can be stepped on by a constructor.

The distance between the tread assembly 21 and the outer frame 11 may be adjustable or may be set to be non-adjustable. When the distance between the tread assembly 21 and the outer frame 11 is adjustable, the anti-slip and anti-drop device 100 for the climbers of the present embodiment can be adapted to work on electric poles of different sizes.

It should be noted that, the outer frame 11 is provided with the first anti-slip pad 31 and the first protrusion set 32, respectively, to achieve different kinds of gripping. The first anti-slip pad 31 is used to grip the utility pole by using its own resistance, for example: the first anti-slip mat 31 may be, but is not limited to, a rubber mat or the like, and utilizes its superior grip ability and toughness to achieve stable grip. The first protrusion set 32 is a structure having a plurality of spaced cleats 35, which increases the roughness of the surface of the first protrusion set 32, improves friction, and achieves an effective anti-slip effect. The stud 35 may be configured as a rigid raised structure, such as: the material may be, but is not limited to, stainless steel, aluminum alloy, titanium alloy, etc.

The distribution of the first cleat 31 and the first protrusion set 32 on the outer frame 11 may be various, such as: the first anti-slip pads 31 and the first protrusion groups 32 are distributed at intervals along the length direction X of the outer frame 11; or may be spaced apart in the thickness direction of the outer frame 11, i.e., perpendicular to the outward or inward direction of the sheet in fig. 2, etc.

Similarly, the second anti-slip pad 33 and the second protrusion set 34 can respectively achieve two different gripping on the tread assembly 21, and the second anti-slip pad 33 is used for gripping the utility pole by using its own resistance, for example: the second anti-slip pad 33 may be, but is not limited to, a rubber pad or the like, and utilizes its better grip ability and toughness to achieve stable grip. The second protrusion set 34 is a structure having a plurality of spaced cleats 35, which increases the roughness of the surface of the second protrusion set 34, improves friction, and achieves an effective anti-slip effect.

It should be noted that the shapes of the cleats 35 in the first and second protrusion sets 32, 34 may be of various designs, such as: the anti-slip protrusions 35 may be saw-toothed, etc.

Further, referring to fig. 2, the first anti-slip pad 31 and the first protrusion set 32 are disposed at intervals along the length direction X of the outer frame 11. It can be seen that the first cleat 31 is spaced from the first projection set 32 to affect each other when the outer frame 11 is grasped on a pole. At this time, structural deformation generated by the stress of the first anti-slip pad 31 does not or less acts on the first protrusion group 32, so as to avoid interference with the grabbing effect of the first protrusion, and realize an effective and stable anti-slip effect.

In order to enhance the gripping performance of the outer frame 11 as much as possible and achieve a better anti-slip effect, the end of the first anti-slip pad 31 away from the first protrusion set 32 may be extended to the end of the outer frame 11 away from the connecting member 12, and the end of the first protrusion set 32 away from the first anti-slip pad 31 may be extended to the end of the outer frame 11 close to the connecting member 12.

Further, referring to FIG. 2, the distance between the first cleat 31 and the first bump set 32 is denoted as D, where 3 cm.ltoreq.D.ltoreq.6 cm. It is understood that the spacing between the first cleat 31 and the first bump set 32 may affect the overall cleat performance. If the distance D between the two is too large, a larger area without a grabbing structure exists in the outer frame 11, so that the effective grabbing area on the outer frame 11 is reduced, the contact area between the outer frame and a telegraph pole is reduced, and the anti-skid effect is reduced. If the distance D between the two is too small, the deformation of the first anti-slip pad 31 during the adhesion is easy to act on the first protrusion set 32, affecting the adhesion capability of the first protrusion set 32, and reducing the anti-slip effect.

For this purpose, the distance D may be between 3cm and 6cm, for example: may be, but is not limited to, 3cm, 3.5cm, 4cm, 4.5cm, 5cm, 5.5cm, 6cm, etc. Thus, the distance D is controlled to be 3 cm-6 cm, so that the influence of the first anti-slip pad 31 on the first protrusion group 32 can be avoided; but also can avoid the larger area of the outer frame 11 without a grabbing structure, and increase the contact area between the outer frame and a telegraph pole, so that the grabbing performance of the whole device is better.

It should be noted that, the specific measurement method of the space between the first cleat 31 and the first bump set 32 may be: taking a point on the surface of the outer frame 11 closest to the connecting piece 12 of the first non-slip mat 31; taking a point of the first protrusion set 32 farthest from the connecting piece 12 on the surface of the outer frame 11; finally, two points are connected, and the length of the connection can be identified as a distance D.

In some embodiments, referring to fig. 3, the second anti-slip pads 33 and the second protrusion sets 34 are spaced apart along the length direction X of the outer frame 11 on the tread assembly 21. The first set of protrusions 32 is closer to the connector 12 than the first cleat 31 and the second set of protrusions 34 is farther from the connector 12 than the second cleat 33. It can be seen that the ordering between the first protrusion set 32 and the first anti-slip pad 31 and the ordering between the second protrusion set 34 and the second anti-slip pad 33 are opposite, so that the distribution between the first protrusion set 32 and the second protrusion set 34 and the first anti-slip pad 31 and the second anti-slip pad 33 is closer to 180 ° on the utility pole when the utility pole is held tightly. Therefore, the utility model forms a surrounding symmetrical structure to the telegraph pole, so that the grabbing force of the device to the telegraph pole is more balanced, the anti-skid effect is better, and the personal safety of constructors is greatly ensured.

Of course, in other embodiments, the first protrusion set 32 is distal from the connector 12 relative to the first cleat 31 and the second protrusion set 34 is proximal to the connector 12 relative to the second cleat 33. By the design, the grabbing force of the device to the telegraph pole is more balanced, the anti-skid effect is better, and the personal safety of constructors is greatly ensured.

In some embodiments, referring to fig. 3, the tread assembly 21 includes a first tread member 211 and a second tread member 212. The first tread member 211 and the second tread member 212 are disposed on the inner frame 22 at intervals along the length direction X of the outer frame 11, and the second tread member 212 is close to the connecting member 12 relative to the first tread member 211, one of the second anti-skid pad 33 and the second protrusion set 34 is disposed on the first tread member 211, and the other is disposed on the second tread member 212. Since the first tread member 211 is closer to the connecting member 12, the sole of the constructor is stepped on the first tread member 211 and the heel is stepped on the second tread member 212 at the time of climbing, so that the constructor can stably tread.

It should be noted that, the first tread element 211 and the second tread element 212 may be fixedly connected to the inner frame 22; also adjustable connections, such as: the first tread member 211 and the second tread member 212 are respectively fixed to different mounting holes on the inner frame 22, and position adjustment is achieved, so that the tread assembly 21 is more suitable for the foot size of a constructor.

Meanwhile, the tread surfaces of the first tread piece 211 and the second tread piece 212 may be provided as inclined surfaces on the inner frame 22, respectively, such as: the tread surfaces of the first tread piece 211 and the second tread piece 212 are inclined towards one side of the enclasping space 40 respectively, so that when climbing, the first tread piece 211 and the second tread piece 212 are stepped on and then tend to be more flat or slightly inclined inwards, the feet are ensured to stand stably, and the construction safety is greatly improved.

Alternatively, the second protrusion group 34 may be disposed at a side of the first tread 211 facing the enclasping space 40, and the second cleat 33 is disposed on a side of the second tread 212 facing the enclasping space 40; alternatively, the second protrusion set 34 may be disposed at a side of the second tread 212 facing the enclasping space 40, and the second cleat 33 is disposed on a side of the first tread 211 facing the enclasping space 40.

Further, referring to fig. 3, tread assembly 21 further includes a first strap 213 and a second strap 214. The first binding band 213 and the second binding band 214 are respectively and correspondingly arranged on the first treading piece 211 and the second treading piece 212, the first binding band 213 is used for fixing the sole, and the second binding band 214 is used for fixing the heel. Thus, through the first binding belt 213 and the second binding belt 214, the sole and the heel are stably fixed, the constructor is ensured to stably stand, and the falling risk is avoided.

It should be noted that the first strap 213 may be configured to be elastic, for example: the first strap 213 is provided with an elastic buckle for adjusting the length of the first strap 213 and stably tightening the sole. Of course, second strap 214 may also be configured to be elastic.

In some embodiments, referring to fig. 3, at least one of the first tread element 211 and the second tread element 212 can be adjusted on the inner frame 22 along the length direction X of the outer frame 11. Therefore, when at least one of the first tread member 211 and the second tread member 212 can be adjusted along the length direction X, the distance between the first tread member 211 and the second tread member 212 can be adjusted according to the foot size of the constructor, so that the tread assembly 21 is more suitable for the constructor, and the safety of construction is improved.

It should be noted that, the first tread element 211 or the second tread element 212 may be adjusted on the inner frame 22 in various ways, for example: the inner frame 22 is provided with a plurality of mounting holes along the length direction X, and the first treading piece 211 or the second treading piece 212 can be fixed in different mounting holes to realize the change of positions; alternatively, a screw and slider structure is provided on the inner frame 22, and the slider is driven to move by the screw, changing the interval between the first tread member 211 and the second tread member 212, and the like.

In some embodiments, referring to fig. 3, the tread mechanism 20 further includes a mounting seat 23. The inner frame 22 is connected to the connecting piece 12 by means of a mounting seat 23. Thus, the inner frame 22 is stably fixed on the connecting piece 12 through the mounting seat 23, so that the structure of the whole device is better and more stable, and the construction safety is improved.

Alternatively, the attachment of the mounting block 23 to the connector 12 may be, but is not limited to, welding, clamping, bolting, pinning, riveting, etc.

In some embodiments, referring to FIG. 3, tread mechanism 20 further includes a fastener 24. Mount 23 is adjustable on connector 12 and fasteners 24 are used to lock mount 23 to connector 12. It can be seen that when the position of the mounting seat 23 needs to be adjusted, the fastener 24 can be loosened to release the fixing of the mounting seat 23; after release, the mounting block 23 is slid or moved, changing the position of the mounting block 23 on the connector 12; after the position is in place, the mounting block 23 is again secured to the connection by fasteners 24.

Because the mounting seat 23 can be adjusted on the connecting piece 12, the distance between the treading assembly 21 and the outer frame 11 can be adjusted, so that the climber anti-slip and anti-drop device 100 can be adjusted according to the size of a telegraph pole, and the stability and the safety of the device are improved.

Alternatively, fastener 24 may be, but is not limited to, a bolt, a pin, or the like.

Specifically, the fastener 24 may be a butterfly screw, which not only prevents slipping during use, but also is convenient and quick to fix.

In some embodiments, referring to fig. 2 and 3, a side of the outer frame 11 facing the enclasping space 40 includes a first gripping surface 111, and the first gripping surface 111 is concave along a side facing away from the enclasping space 40. The side of the inner frame 22 facing the enclasping space 40 comprises a second gripping surface 221, the second gripping surface 221 being concave along the side facing away from the enclasping space 40. It can be seen that the first gripping surface 111 and the second gripping surface 221 are respectively provided with concave curved surfaces, so that the electric pole can be better gripped between the outer frame 11 and the tread assembly 21, and the anti-skid effect is improved.

The first cleat 31 and the first bump group 32 are disposed on the first attaching surface 111 at intervals, respectively. Meanwhile, the first grip surface 111 may be constructed in a semicircular arc structure.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
