Description

Technical Field

[0001] The present invention relates to a climbing device, and in particular to a braking device for climbing. Background Art

[0002] When electric power related workers climb utility poles for operation, they need to use a braking device, commonly known as a footrest. The footrest generally includes a foot pedal, a pole hook connected to the foot pedal, and an anti-slip part. Since the diameter of the utility pole gradually decreases from bottom to top, it is necessary to adjust the opening size of the footrest during the climbing process. Especially for high-voltage utility poles, it is necessary to adjust the opening size multiple times during the entire climbing process.

[0003] Currently, the adjustment method for the opening size of the footrest is to manually pull the pole hook towards the foot pedal to adjust the size of the clamping opening. Although this adjustment method can cooperate with different positions of different diameters at different heights of the utility pole, the manual adjustment method is inconvenient to operate, and there are certain safety hazards during the operation, especially for high-altitude climbing operations. Summary of the Invention

[0004] The present invention aims at the problems existing in the footrest climbing device in the prior art, and provides a braking device for climbing.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions: A braking device for climbing, including a braking device body. The braking device body includes a foot pedal, a buckle body connected to the foot pedal, and a pole hook that can slide in the buckle body. The foot pedal is also provided with an anti-slip part that cooperates with the pole hook. The anti-slip part and the pole hook together form a clamping opening with one end open. The foot pedal is also connected with a pole hook adjusting mechanism. The pole hook adjusting mechanism includes a driven wheel that can drive the pole hook to reciprocate in the buckle body and a driving wheel connected to the driven wheel for driving the driven wheel to move. The driving wheel can roll on the outer wall of the utility pole during the climbing process of the braking device body.

[0006] Preferably, a buckle body connecting rod is fixed on the foot pedal. The buckle body connecting rod is bent from a steel pipe, and one end forms a fixed end fixed to the bottom of the foot pedal, and the other end forms an extending end extending out of the foot pedal and bent into an arc shape. One side of the buckle body is fixed on the side wall of the extending end, and a sliding hole for the pole hook to pass through is formed in the middle of the buckle body.

[0007] Preferably, the driving wheel is arranged on the side of the foot pedal facing the clamping opening, the driven wheel is installed on the side wall of the buckle body, and driven teeth meshing with the driven wheel are provided on the outer wall of the pole hook. The rotation of the driven wheel can drive the movement of the pole hook in the buckle body to achieve unlocking or clamping actions.

[0008] Preferably, it also includes a transmission mechanism arranged between the driving wheel and the driven wheel, the transmission mechanism includes a driving shaft for installing the driving wheel and a driven shaft arranged on one side of the buckle body for installing the driven wheel, and also includes a connecting gear arranged at the lower part of the buckle body and a connecting shaft for installing the connecting gear, a driven coaxial wheel meshing with the connecting gear is installed on the driven shaft, and the connecting shaft and the driving shaft are connected by a transmission belt.

[0009] Preferably, the footrest is further provided with an anti-slip mounting mechanism, comprising an anti-slip mounting base and a mounting bracket connected to the anti-slip mounting base via a pivot shaft. The anti-slip portion is secured to one end of the anti-slip mounting bracket, and the other end of the anti-slip mounting bracket is provided with an auxiliary pedal for the back of the foot to press against the outer wall of the utility pole. A torsion spring is provided at the pivot shaft to drive the anti-slip portion away from the utility pole. The torsion spring resets the auxiliary pedal, thereby ensuring a consistent climbing motion using the foot buckle.

[0010] Preferably, the anti-slip mounting frame includes a pedal mounting frame, which includes a U-shaped frame and a reinforcing rod disposed within the U-shaped frame. The pedal mounting frame also includes an anti-slip securing rod, one end of which is used to secure the anti-slip portion, and the other end of which is connected to the U-shaped frame and has a rotation hole connected to the rotation shaft at the connection. The auxiliary pedal is disposed at the end of the U-shaped frame away from the rotation hole. The structure of the anti-slip mounting frame enables the anti-slip portion to tighten and loosen against the utility pole.

[0011] Preferably, the anti-slip portion includes an anti-slip bracket with two rubber anti-slip rollers mounted on either side. When the auxiliary pedal is flush with the foot pedal, the rubber anti-slip rollers abut against the outer wall of the utility pole, and the upper end of the anti-slip bracket abuts against the lower end of the drive shaft. The structural design of the anti-slip portion enables it to better grip the utility pole while abutting against the lower end of the drive shaft, effectively ensuring stability during the gripping process.

[0012] Preferably, a footrest mounting base is fixed to the U-shaped frame, the footrest mounting base being provided with a bolt mounting base and a guide hole. The auxiliary pedal is fixed to the bolt mounting base by bolts, and a guide rod is provided on the lower end surface of the auxiliary pedal for insertion into the guide hole. This mounting method of the auxiliary pedal allows for adjustment of the height of the auxiliary pedal to better facilitate the locking operation.

[0013] As preferably, the end of the surrounding rod hook away from the pedal is sleeved with a sleeve, the sleeve being a rubber sleeve or a steel sleeve with serrations on the outer wall. A replaceable sleeve is provided so that the foot buckle can be adapted to different rod bodies.

[0014] Preferably, a limit pin is provided at the end of the enclosure hook near the foot pedal for limiting the buckle body. The setting of the limit pin can prevent the enclosure hook from falling out of the sliding hole.

[0015] Due to the adoption of the above technical solutions, the present invention has remarkable technical effects: The present invention can reasonably utilize the original foot movements during climbing with the footrests to achieve the clamping and loosening of the utility pole, and the size of the clamping opening will be automatically adjusted according to the outer diameter of the utility pole during the entire climbing process, without additional adjustment actions. The operation is simple and convenient, and it is well-suited for high-altitude climbing operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0024] Embodiment 1 In this embodiment, a climbing braking device is provided, that is, the footrest used during climbing operations. As Figures 1 - 6 shown, it includes a brake device body 1. The brake device body 1 includes a foot pedal 101. A buckle body 102 and a pole hook 103 that can slide within the buckle body 102 are connected to the foot pedal 101. An anti-slip part 104 that cooperates with the pole hook 106 is further provided on the foot pedal 101. The anti-slip part 104 and the pole hook 103 together form a clamping opening 134 with one end open. A pole hook adjusting mechanism is also connected to the foot pedal 101. The pole hook adjusting mechanism includes a driven wheel 105 that can drive the pole hook 103 to reciprocate within the buckle body 102 and a driving wheel 106 connected to the driven wheel 105 for driving the driven wheel 105 to move. The driving wheel 106 can roll on the outer wall of the utility pole during the climbing process of the brake device body 1.

[0025] When the footrest climbing device provided in this embodiment is in use, it can reasonably utilize the original foot movements during climbing with the footrests to achieve the clamping and loosening of the utility pole. Moreover, during the entire climbing process, the size of the clamping opening 134 will automatically adjust according to the outer diameter of the utility pole, without the need for additional adjustment actions. The operation is simple and convenient. For high-altitude operations, reducing unnecessary movements is beneficial to operation safety and difficulty.

[0026] Specifically, a buckle connecting rod 107 is fixed on the footrest 101. The buckle connecting rod 107 is formed by bending a steel pipe, and one end forms a fixed end 108 fixed to the bottom of the footrest 101, and the other end forms an extending end 109 that extends out of the footrest 101 and is bent into an arc shape. One side of the buckle 102 is fixed to the side wall of the extending end 109. A sliding hole 110 for the pole hook 103 to pass through is formed in the middle of the buckle 102. The pole hook 103 is configured as a straight rod with one end cooperating with the sliding hole 110 and a bent rod cooperating with the utility pole at the other end. A limit pin 133 for limiting the buckle 102 is provided at the end of the pole hook 103 close to the footrest 101 to prevent the pole hook 103 from slipping out of the sliding hole 110.

[0027] The driving wheel 106 is arranged on one side of the footrest 101 facing the clamping opening 134. The driven wheel 105 is installed on the side wall of the buckle 102. A driven tooth 111 meshing with the driven wheel 105 is provided on the outer wall of the pole hook 103. It also includes a transmission mechanism arranged between the driving wheel 106 and the driven wheel 105. The transmission mechanism includes a driving shaft 135 for installing the driving wheel 106 and a driven shaft 112 arranged on one side of the buckle 102 for installing the driven wheel 105. It also includes an interlocking gear 113 arranged at the lower part of the buckle 102 and an interlocking shaft 114 for installing the interlocking gear 113. A driven coaxial gear 115 meshing with the interlocking gear 113 is installed on the driven shaft 112. The interlocking shaft 114 is connected to the driving shaft 135 through a transmission belt 116.

[0028] During the climbing process of the staff member, when climbing upward, one foot is fixed on the electric pole, and the other foot is lifted upward to release the locking force on the foot buckle. At the same time, during the process of moving the foot buckle upward and away from the opening side of the clamping opening 134, the pedal 101 is first slightly moved toward the electric pole side, so that the driving wheel 106 abuts against the outer wall of the electric pole. Then, as the foot buckle moves, the driving wheel 106 is driven to rotate. After the driving wheel 106 rotates, it will drive the pole hook 103 to move away from the anti-slip part 104 through the transmission mechanism, so that the clamping opening 134 expands, thus facilitating the detachment of the foot buckle from the upper part of the electric pole at this time and smoothly moving to the next position; similarly, when the foot buckle is lifted to the next position, it moves in the reverse direction, so that the driving wheel 106 first adheres to the side wall of the electric pole, and then gradually makes the pole hook 103 move toward the electric pole side. At this time, the driving wheel 106 moves in the reverse direction, and then it will drive the pole hook 103 to move toward the anti-slip part 104 through the transmission mechanism, so that the clamping opening 134 tightens. Then, the anti-slip part 104 abuts tightly against the electric pole, and the structure cooperates with the pole hook 103 for locking. The entire climbing process only requires the feet to move obliquely along with the electric pole, and the actions can be completed in one go, and the operation is relatively convenient.

[0029] During the process of the pole hook 103 moving toward the electric pole side, it will automatically adjust the movement stroke according to the diameter of the electric pole. That is, when climbing to a thinner electric pole, the pole hook 103 will move a greater stroke toward the opening side of the clamping rod, so that the driving wheel 106 rotates more turns. Then, the pole hook 103 moves a greater stroke toward the anti-slip part 104, so that the clamping opening 134 contracts less. In this process, for different positions of electric poles with different thicknesses, there is no need to specifically adjust, but it is naturally formed during the climbing process and automatically adapts to different positions of the electric poles, with the characteristics of high efficiency and convenient operation.

[0030] In this embodiment, an anti-slip part installation mechanism is further provided on the pedal 101. The anti-slip part installation mechanism includes an anti-slip part installation seat 117 and an installation frame 119 whose middle part is connected to the anti-slip part installation seat 117 through a rotating shaft 118. The anti-slip part 104 is fixed to one end of the anti-slip part installation frame 119. The other end of the anti-slip part installation frame 119 is provided with an auxiliary pedal 120 for the heel of the foot to step on to abut the anti-slip part 104 against the outer wall of the electric pole. A torsion spring 121 for driving the anti-slip part 104 to move away from the electric pole is provided at the rotating shaft 118.

[0031] Among them, the anti-slip part installation frame 119 includes a pedal installation frame 119. The pedal installation frame 119 includes a U-shaped frame 122 and a reinforcing rod 123 arranged inside the U-shaped frame 122. It further includes an anti-slip part fixing rod 124. One end of the anti-slip part fixing rod 124 is used to fix the anti-slip part 104, and the other end is connected to the U-shaped frame 122 and a rotating hole connected to the rotating shaft 118 is provided at the connection part. The auxiliary pedal 120 is arranged at one end of the U-shaped frame 122 away from the rotating hole.

[0032] In addition, the anti-slip portion 104 includes an anti-slip bracket 125. Two rubber anti-slip rollers 126 extending toward both sides are mounted on the anti-slip bracket 125. When the auxiliary pedal 120 is flush with the foot pedal 101, the rubber anti-slip rollers 126 are pressed against the outer wall of the utility pole, and the upper end face of the anti-slip bracket 125 is pressed against the lower end face of the drive shaft 135.

[0033] When the anti-slip portion mounting mechanism is working, the operator steps on the foot pedal 101. When it is necessary to lock the foot buckle on the utility pole, the rear foot sole steps on the auxiliary pedal 120, causing the pedal mounting frame 119 to rotate downward and the anti-slip portion fixing rod 124 to rotate upward until the anti-slip portion 104 is pressed against the outer wall of the utility pole, cooperating with the pole hook 103 to form a lock. At the same time, the driving wheel 106 is not in contact with the utility pole, which can prevent wear of the driving wheel 106. Similarly, it can prevent the roller from rubbing against the utility pole and causing rotation when the operator moves the foot after stepping on it, thus avoiding the serious consequence that the whole foot buckle moves and detaches.

[0034] A foot pedal mounting seat 127 is fixed on the U-shaped frame 122. A bolt mounting seat 128 and a guide hole 129 are provided on the foot pedal mounting seat 127. The auxiliary pedal 120 is fixed on the bolt mounting seat 128 by bolts, and a guide rod 130 inserted into the guide hole 129 is provided on the lower end face of the auxiliary pedal 120. Since the sizes and bending degrees of the foot soles of each operator are different, by adjusting the height of the pedal, the operator can adjust the pedal to a suitable position for himself. When operating, try to step on the pedal with the rear foot sole when it is necessary to step on the pedal, and avoid applying a large force to the pedal with the rear foot sole when it is not necessary to step on it.

[0035] In addition, a sleeve is sleeved on the end of the pole hook 103 away from the foot pedal 101. The sleeve is a rubber sleeve 131 or a steel sleeve 132 with sawteeth on the outer wall, as Figure 7 shown. The sleeve is sleeved on the pole hook 103, and a limit bolt for limiting the sleeve is provided at the end of the pole hook 103. The provision of a replaceable sleeve enables this foot buckle to be applicable to different pole bodies. The rubber sleeve 131 can be applied to a cement pole, and the serrated steel sleeve 132 can be applied to a wooden pole.

[0036] It is easy to understand that those skilled in the art can combine, split, recombine, etc. the embodiments of the present application based on one or several embodiments provided by the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.

[0037] In summary, the above are only the preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
