Description

Technical Field

[0001] The invention belongs to the technical field of electric power construction, and in particular relates to an electric power tower climbing assisting foot buckle. Background Art

[0002] Power towers are steel structure products, including iron tower structures, pole tower structures, etc., which are all supporting equipment for power lines.

[0003] In order to prevent unauthorized personnel from climbing on the pole tower structure, the original ladder design has been cancelled. Therefore, when climbing and repairing, additional power-assisting equipment is needed. The foot buckle is a kind of pole climbing auxiliary equipment often used by power workers. Before use, the pole climber needs to fix the pole climber on both feet, use the lever effect, and with the help of the body's own weight, make the other side tightly buckled on the pole, generating greater friction, making it easier for people to climb.

[0004] In order to solve the problem of safety hazards caused by the need to remove and reinstall the power tower climbing assistance device in the prior art during use, the power tower climbing assistance device with application number CN2020112726823 includes two sleeves, and a foot pedal is provided on the outer wall of the sleeve. The sleeve includes at least two sleeve assemblies, and a locking block is slidably connected to the inner wall of the sleeve assembly through a slide groove. The distance from the upper end of the slide groove to the outer wall of the sleeve assembly is greater than the distance from the lower end of the slide groove to the outer wall of the sleeve assembly. The adjacent sleeve assemblies are hinged, and the sleeve assemblies at the head and tail ends are provided with locking mechanisms.

[0005] However, when the above solution is implemented, on the one hand, it is not convenient to adjust the size of the sleeve, and the sleeve structure is large, and the distance between the two feet is too large, which will cause discomfort to the construction workers during long-term operation. On the other hand, during the operation of the foot pedal, the ankle strength needs to be used to apply force outward and downward to utilize the sleeve to form a lock, but at this time the force surface of the foot is limited to the outside of the foot. Long-term climbing work can easily cause fatigue to the construction workers' ankles and outsides of the feet. Summary of the Invention

[0006] The purpose of the present invention is to provide a power tower climbing assist foot buckle, which can be flexibly adjusted according to the size of the tower pole to be climbed, can make full use of the force of the soles of the feet, facilitate the construction workers to climb and ensure construction safety.

[0007] To achieve the above-mentioned object, the present invention provides a power tower climbing assist foot buckle, comprising a connecting base, with adjustable clamping arms obliquely connected outward at both ends of the connecting base. The connecting base cooperates with the two adjustable clamping arms to form a V-shaped structure, and the ends of the two adjustable clamping arms away from the connecting base are connected to arc-shaped locking arms via bolts.

[0008] A fixing bracket is vertically connected to the lower side of the connecting seat, and a locking pressure block is connected to the fixing bracket on the side facing the arc-shaped locking arm;

[0009] The side of the connecting seat away from the adjusting clamping arm is connected to a foot plate through an upwardly inclined support arm, and arc-shaped limiting end plates are provided at both ends of the foot plate. The side of the foot plate away from the connecting seat is provided with an arc-shaped limiting side plate, and a fixing rope is connected to the arc-shaped limiting side plate. The support arm is provided with a lifting ring connected to the fixing rope.

[0010] As a further solution of the present invention: the support arm and the foot plate are located in the same plane, forming an angle of 120°-130° with the fixing frame.

[0011] As a further solution of the present invention: a plurality of connecting holes are provided on the adjusting clamp arm along the length direction of the adjusting clamp arm, connecting ear plates are provided at both ends of the arc-shaped locking arm, and the bolts pass through the connecting ear plates and the connecting holes to fix the adjusting clamp arm and the arc-shaped locking arm.

[0012] As a further solution of the present invention: a downward inclined surface is provided on a side of the locking pressure block away from the fixing frame.

[0013] As a further solution of the present invention: a reinforcing plate is connected to the bottom end of the fixing frame and the bottom of the foot plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The adjustable clamping area is formed by the adjustable clamping arm and the arc-shaped locking arm, which can be adaptively adjusted according to the tower size;

[0016] The angle plate is connected to the support arm and the connecting seat to form a certain inclination angle, so that the entire sole of the foot can be used to exert force outward and downward during construction, which can better borrow the body's own gravity, thereby avoiding strain on the construction workers' ankles and the outer side of the foot;

[0017] A downward inclined surface is provided on the locking block. When the foot plate acts on the connecting seat to tilt the connecting seat and the arc-shaped locking arm to lock the tower pole, the inclined surface can increase the contact area with the tower pole, thereby enhancing the fastening effect.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, a power tower climbing assist foot buckle includes a connecting base 1, with adjustable clamping arms 2 connected obliquely outward at both ends of the connecting base 1. The connecting base 1 and the two adjustable clamping arms 2 form a V-shaped structure. The ends of the two adjustable clamping arms 2 away from the connecting base 1 are connected to arc-shaped locking arms 6 by bolts 4. The arc-shaped locking arms 6, the adjustable clamping arms 2, and the connecting base 1 form an annular structure that sleeves the tower pole.

[0023] A fixing bracket 9 is vertically connected to the bottom of the connecting seat 1, and a locking pressure block 8 is connected to the fixing bracket 9 on the side facing the arc-shaped locking arm 6. The locking pressure plate can cooperate with the arc-shaped locking arm 6 to form a connection and positioning on the tower;

[0024] The side of the connecting seat 1 away from the adjusting clamping arm 2 is connected to the foot plate 14 through the support arm 11 which is tilted upward. The foot plate 14 is tilted under the connection action of the support arm 11, which can more conveniently apply force outward, so that the sole of the foot can act on the foot plate 14 as a whole. Arc-shaped limiting end plates 13 are provided at both ends of the foot plate 14, and an arc-shaped limiting side plate 15 is provided on the side of the foot plate 14 away from the connecting seat 1. The arc-shaped limiting end plates 13 and the arc-shaped limiting side plates 15 can form a comprehensive limiting effect on the foot. A fixing rope 16 is connected to the arc-shaped limiting side plate 15, and a lifting ring 12 connected to the fixing rope 16 is provided on the support arm 11. The final fixation of the foot is achieved by connecting the fixing rope 16 to the lifting ring 12, which is convenient for using the foot to drive the foot buckle to move upward as a whole during construction operations.

[0025] Furthermore, the support arm 11 and the foot plate 14 are located in the same plane, forming an angle of 120°-130° with the fixing frame 9. If the angle is too large, it is not convenient for the foot to step hard on the foot plate 14. If the angle is too small, it cannot exert an outward and downward force.

[0026] In order to facilitate the adjustment of the size of the annular structure formed by the arc-shaped locking arm 6, the adjusting clamp arm 2 and the connecting seat 1 to sleeve the tower pole, a plurality of connecting holes 3 are provided on the adjusting clamp arm 2 along the length direction of the adjusting clamp arm 2, and connecting ear plates 5 are provided at both ends of the arc-shaped locking arm 6. Bolts 4 pass through the connecting ear plates 5 and the connecting holes 3 to fix the adjusting clamp arm 2 and the arc-shaped locking arm 6. Before construction work, the connection position of the arc-shaped locking arm 6 and the adjusting clamp arm 2 should be adjusted according to the size of the tower pole.

[0027] In order to ensure the friction effect of the locking pressure block 8 on the tower pole, a downward inclined surface 7 is provided on the side of the locking pressure block 8 away from the fixing frame 9, which can fully fit the surface of the tower pole after the connecting seat 1 drives the locking pressure block 8 to rotate downward.

[0028] In order to further strengthen the structural stability of the foot buckle, a reinforcing plate 10 is connected between the bottom end of the fixing frame 9 and the bottom of the foot plate 14 to improve the overall support strength and ensure construction safety.

[0029] The working process of the present invention is as follows: according to the size of the tower, a suitable connection hole 3 is selected to connect with the arc-shaped locking arm 6. The construction worker wears a safety belt, places his feet on the footboard 14, and fixes them with the fixing rope 16 before starting to work.

[0030] By utilizing its own gravity, the sole of the foot is fully attached to the foot plate 14. By utilizing the inclination of the foot plate 14 and naturally applying force outward and downward, the foot plate 14 can be flipped downward to drive the connecting seat 1 and the locking pressure block 8 to rotate. The inclined surface 7 of the locking pressure block 8 is in contact with the tower pole, and the arc-shaped locking arm 6 is in contact with the tower pole, thereby achieving locking and positioning. In actual use, the locking pressure block 8, the arc-shaped locking arm 6, and the splint can be covered with wear-resistant and non-slip pads to improve the friction effect and avoid damage to the tower pole.

[0031] When ascending, naturally lift one foot. As the foot is lifted, the contact between the locking block 8 and the tower pole is released, thereby driving the foot buckle to move upward as a whole. After moving a certain distance, the sole of the foot steps outward, and the tower pole is locked by the locking block 8 and the arc-shaped locking arm 6. Alternate operation of the left and right feet can achieve ascent;

[0032] When descending, naturally lift one foot. As the foot is lifted, the contact between the locking pressure block 8 and the tower pole will be released. At this time, the foot will be retracted inward and the weight of the foot buckle will be used to fall. After moving a certain distance, the sole of the foot will step outward, and the tower pole will be locked using the locking pressure block 8 and the arc-shaped locking arm 6. The left and right feet can be used alternately to achieve descent.
