Description

Technical Field

[0001] This invention belongs to the field of power maintenance tools technology, specifically relating to an electrician's foot clip. Background Technology

[0002] Utility poles are widely used as part of the infrastructure for power equipment. While aerial work platforms and other climbing equipment are used in routine maintenance of utility poles, manual pole climbing by maintenance personnel remains the most common method for line operation and maintenance. Foot straps are curved iron tools worn on shoes by maintenance personnel for climbing utility poles. They utilize the lever principle, using the weight of the person to grip the pole on one side, generating significant friction and making climbing easier. When the climber lifts their foot, the weight on the foot decreases, and the foot strap automatically loosens. Foot straps are lightweight, high-strength, and resilient; they are also adjustable, portable, safe, reliable, and easy to carry, making them ideal tools for electricians climbing various sizes of concrete or wooden poles.

[0003] Chinese patent document CN219662805U discloses an adjustable foot strap for electricians climbing utility poles. It includes an arc-shaped strap and a foot pedal structure. The foot pedal structure is rotatably connected to one end of the arc-shaped strap and located on the outside of the strap. A limiting structure on the arc-shaped strap restricts the rotational position of the foot pedal structure. The foot pedal structure includes a pedal and a support rod. One side of the pedal is rotatably connected to the arc-shaped strap, and the opposite side is connected to one end of the support rod. The other end of the support rod can abut against the utility pole. The support rod is located below the pedal and its length is adjustable. This electrician's foot strap allows the pedal to be perpendicular to the utility pole when climbing, concentrating the force on the sole of the foot rather than the side, thus improving comfort.

[0004] Traditional foot catches can meet the needs of pole climbing operations in most situations. However, the friction between the foot catches and the pole is easily affected by weather and environment. For example, in rainy or snowy weather, the friction between traditional foot catches and the pole is insufficient, which may lead to the danger of slipping or falling off the pole when climbing. Once this happens, it is easy to fall and cause injury to the workers. Summary of the Invention

[0005] The purpose of this invention is to provide an electrician's foot clip to solve the aforementioned problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electrician's foot catch, comprising a foot pedal, a secondary catch plate, a foot catch bracket, a support sleeve, a linear connecting rod, a main catch plate, a telescopic drive device, an acceleration detection device, and a controller. The secondary catch plate is connected to the foot pedal, one end of the foot catch bracket is connected to the foot pedal, and the other end of the foot catch bracket is connected to the support sleeve. One end of the linear connecting rod is connected to the main catch plate, and the other end of the linear connecting rod is slidably engaged with the support sleeve. The telescopic drive device is used to drive the linear connecting rod to slide along the length direction of the support sleeve, so that the main catch plate moves closer to or away from the secondary catch plate. Both the acceleration detection device and the telescopic drive device are connected to the controller. The acceleration detection device is used to detect the acceleration when the foot pedal falls, and the controller is used to control the telescopic drive device to start when the acceleration of the foot pedal reaches a preset value, so that the main catch plate moves closer to the secondary catch plate and thus grips the utility pole.

[0007] This invention employs the aforementioned technical solution. The telescopic drive device can drive the linear connecting rod to slide along the length of the support sleeve, causing the main buckle plate to move closer to or further away from the secondary buckle plate. When the main buckle plate moves away from the secondary buckle plate, the opening of the foot buckle increases; when the main buckle plate moves closer to the secondary buckle plate, the opening of the foot buckle decreases, accommodating utility poles of different specifications. This invention utilizes a telescopic drive device to drive the linear connecting rod to slide along the length of the support sleeve, which allows for convenient adjustment of the foot buckle opening size. The operation is simple and quick, eliminating the need for operators to bend over and manually adjust, thus increasing the practicality of the foot buckle.

[0008] Furthermore, during power maintenance work, when the worker and foot catch fall together, the acceleration detection device detects that the acceleration of the foot catch during the fall reaches a preset value. The controller then activates the telescopic drive device, causing the main catch plate to move closer to the secondary catch plate. This allows the main and secondary catch plates to grip the utility pole tightly, increasing the friction between the foot catch and the utility pole, reducing the worker's falling speed, preventing falls, minimizing physical injury to the worker, and effectively improving the safety of the foot catch.

[0009] As an optional implementation of the above technical solution, the telescopic drive device includes a drive mechanism, a threaded rod, and a movable connecting plate. The drive mechanism is mounted on the support sleeve, and the output end of the drive mechanism is connected to the threaded rod. The movable connecting plate is connected to the linear connecting rod, and a threaded hole adapted to the threaded rod is provided on the movable connecting plate.

[0010] As an optional implementation of the above technical solution, the driving mechanism includes a drive motor, which is connected to a controller. The drive motor is connected to a reduction gearbox, and the output end of the reduction gearbox is connected to a threaded rod.

[0011] As an optional implementation of the above technical solution, both ends of the threaded rod are provided with positioning detection devices, and the positioning detection devices are connected to the controller.

[0012] As an optional embodiment of the above technical solution, the outer wall of the support sleeve is provided with a support seat, and the drive mechanism is mounted on the support seat.

[0013] As an optional embodiment of the above technical solution, the support base includes a support base plate and a bearing mounting plate. The support base plate is connected to the outer wall of the support sleeve, and the support base plate and the bearing mounting plate are connected in an L-shaped structure. The bearing mounting plate is provided with a bearing. The drive mechanism is mounted on the support base plate, and the threaded rod is rotatably engaged with the bearing mounting plate through the bearing.

[0014] As an optional implementation of the above technical solution, a triangular reinforcing plate is provided between the supporting base plate and the supporting sleeve.

[0015] As an optional implementation of the above technical solution, it also includes a height detection device, which is connected to the controller. The height detection device is used to detect the height of the foot pedal off the ground. When the height of the foot pedal off the ground reaches a preset height, the controller activates the acceleration detection device.

[0016] As an optional implementation of the above technical solution, the acceleration detection device includes an acceleration sensor, and an electromagnetic relay is connected between the acceleration sensor and the controller. When the foot pedal reaches a preset height from the ground, the controller energizes the acceleration sensor through the electromagnetic relay; when the foot pedal is lower than the preset height from the ground, the controller de-energizes the acceleration sensor through the electromagnetic relay.

[0017] As an optional implementation of the above technical solution, the foot pedal is provided with a buckle structure.

[0018] As an optional implementation of the above technical solution, the buckle structure includes an elastic band and two buckle blocks, the two buckle blocks are respectively disposed on both sides of the foot pedal, and the two ends of the elastic band are respectively connected to the two buckle blocks.

[0019] As an optional implementation of the above technical solution, both the main buckle plate and the secondary buckle plate are provided with anti-slip rubber pads on their inner sides.

[0020] The beneficial effects of this invention are as follows: This invention provides an electrician's foot catch, in which an acceleration detection device and a telescopic drive device are both connected to a controller. The acceleration detection device detects the acceleration of the foot pedal during descent, and the controller activates the telescopic drive device when the acceleration of the foot pedal reaches a preset value, causing the main catch plate to move closer to the secondary catch plate and thus grip the utility pole. During power maintenance work, when the worker and the foot catch fall together, the acceleration detection device detects that the acceleration of the foot catch during descent reaches the preset value. The controller then activates the telescopic drive device, causing the main catch plate to move closer to the secondary catch plate, thus gripping the utility pole tightly. This increases the friction between the foot catch and the utility pole, reduces the worker's falling speed, prevents falls, minimizes physical injury to the worker, and effectively improves the safety of the foot catch.

Detailed Implementation

[0023] like Figures 1-3 As shown, this embodiment provides an electrician's foot catch, including a foot pedal 1, a secondary catch plate 2, a foot catch bracket 3, a support sleeve 4, a linear connecting rod 5, a main catch plate 6, a telescopic drive device, an acceleration detection device 7, and a controller 8. The secondary catch plate 2 is connected to the foot pedal 1, one end of the foot catch bracket 3 is connected to the foot pedal 1, and the other end of the foot catch bracket 3 is connected to the support sleeve 4. The surfaces of both the main catch plate 6 and the secondary catch plate 2 are arc-shaped to increase the contact area between the foot catch and the utility pole. Preferably, both the main catch plate 6 and the secondary catch plate 2 have anti-slip rubber pads 21 on their inner sides to increase the friction between the foot catch and the utility pole.

[0024] like Figure 1As shown, one end of the linear connecting rod 5 is connected to the main buckle plate 6, and the other end of the linear connecting rod 5 is slidably engaged with the support sleeve 4. The telescopic drive device is used to drive the linear connecting rod 5 to slide along the length direction of the support sleeve 4, so that the main buckle plate 6 moves closer to or away from the secondary buckle plate 2. The cross-section of the linear connecting rod 5 is rectangular, and correspondingly, the through hole of the support sleeve 4 is rectangular. The telescopic drive device can drive the linear connecting rod 5 to slide along the length direction of the support sleeve 4, so that the main buckle plate 6 moves closer to or away from the secondary buckle plate 2. When the main buckle plate 6 moves away from the secondary buckle plate 2, the opening of the foot buckle increases; when the main buckle plate 6 moves closer to the secondary buckle plate 2, the opening of the foot buckle decreases, which can accommodate different specifications of utility poles. This invention utilizes a telescopic drive device to drive the linear connecting rod 5 to slide along the length direction of the support sleeve 4, which can easily adjust the size of the foot buckle opening. The operation is simple and quick, eliminating the need for operators to bend over and adjust manually, thus increasing the practicality of the foot buckle.

[0025] The acceleration detection device 7 and the telescopic drive device are both connected to the controller 8. The acceleration detection device 7 is used to detect the acceleration of the foot pedal 1 when it falls. The controller 8 is used to control the telescopic drive device to start when the acceleration of the foot pedal 1 reaches a preset value, so that the main buckle plate 6 approaches the auxiliary buckle plate 2 and thus holds the utility pole tightly.

[0026] During power maintenance work, when the worker and foot catch fall together, the acceleration detection device 7 detects that the acceleration of the foot catch during the fall reaches a preset value. Then, the controller 8 controls the telescopic drive device to start, so that the main buckle plate 6 moves closer to the auxiliary buckle plate 2. This causes the main buckle plate 6 and the auxiliary buckle plate 2 to hold the power pole tightly, increasing the friction between the foot catch and the power pole, reducing the worker's falling speed, avoiding a fall accident, reducing physical injury to the worker, and effectively improving the safety of the foot catch.

[0027] Specifically, the telescopic drive device includes a drive mechanism, a threaded rod 9, and a movable connecting plate 10. The drive mechanism is mounted on the support sleeve 4, and its output end is connected to the threaded rod 9. The movable connecting plate 10 is connected to the linear connecting rod 5, and the movable connecting plate 10 has a threaded hole adapted to the threaded rod 9. Preferably, the drive mechanism includes a drive motor 11, which is connected to a controller 8. The drive motor 11 is connected to a reduction gearbox 12, and the output end of the reduction gearbox 12 is connected to the threaded rod 9. The drive motor 11 drives the threaded rod 9 to rotate through the reduction gearbox 12. Because the threaded rod 9 is threadedly engaged with the movable connecting plate 10, the movable connecting plate 10 can slide along the support sleeve 4 with the linear connecting rod 5, causing the main buckle plate 6 to move closer to or further away from the secondary buckle plate 2.

[0028] Furthermore, both ends of the threaded rod 9 are equipped with positioning detection devices 13, which are connected to the controller 8. When the positioning detection device 13 detects that the movable connecting plate 10 is close to the end of the threaded rod 9, the controller 8 controls the drive motor 11 to stop running, thereby improving the safety of the electrician's foot strap.

[0029] In one specific embodiment, the outer wall of the support sleeve 4 is provided with a support base 14, and the drive mechanism is mounted on the support base 14. For example... Figure 2 As shown, specifically, the support base 14 includes a support base plate 15 and a bearing mounting plate 16. The support base plate 15 is connected to the outer wall of the support sleeve 4, and the support base plate 15 and the bearing mounting plate 16 are connected in an L-shaped structure. A bearing is provided on the bearing mounting plate 16. The drive mechanism is mounted on the support base plate 15, and the threaded rod 9 is rotatably engaged with the bearing mounting plate 16 through the bearing. Preferably, a triangular reinforcing plate 17 is provided between the support base plate 15 and the support sleeve 4 to increase the strength of the support base plate 15. The drive motor 11 and the reduction gearbox 12 are fixed on the support base plate 15, and one end of the threaded rod 9 passes through the bearing and is threadedly engaged with the movable connecting plate 10.

[0030] In one specific implementation, such as Figure 3 As shown, the foot buckle also includes a height detection device 18, which is connected to the controller 8. The height detection device 18 is used to detect the height of the foot pedal 1 off the ground. When the height of the foot pedal 1 off the ground reaches a preset height, the controller 8 activates the acceleration detection device 7.

[0031] The height detection device 18 can be a laser rangefinder, which is installed at the bottom of the foot pedal 1. The laser rangefinder is used to detect the height of the foot pedal 1 off the ground. When the height of the foot pedal 1 off the ground is lower than the preset height, that is, the worker is within the safe working height range, the acceleration detection device 7 is not activated at this time. When the height of the foot pedal 1 off the ground reaches the preset height, that is, the worker exceeds the safe working height, the controller 8 activates the acceleration detection device 7. When the worker falls, the acceleration detection device 7 is used to detect the acceleration of the foot pedal 1. When the acceleration of the foot pedal 1 reaches the preset value, the controller 8 controls the drive motor 11 to start, so that the main buckle plate 6 moves closer to the auxiliary buckle plate 2, so that the main buckle plate 6 and the auxiliary buckle plate 2 hold the utility pole tightly, increasing the friction between the foot buckle and the utility pole, reducing the falling speed of the foot buckle, and increasing the safety of electrical maintenance work.

[0032] The acceleration detection device 7 includes an acceleration sensor. An electromagnetic relay connects the acceleration sensor to the controller 8. When the foot pedal 1 reaches a preset height from the ground, the controller 8 energizes the acceleration sensor via the electromagnetic relay. When the foot pedal 1 is below the preset height, the controller 8 de-energizes the acceleration sensor via the electromagnetic relay. When the worker is within the safe working height range, the controller 8 de-energizes the acceleration sensor via the electromagnetic relay, and the acceleration sensor is in an inactive state. When the worker exceeds the safe working height, the controller 8 energizes the acceleration sensor via the electromagnetic relay, and the acceleration sensor is activated, constantly monitoring the worker's working status. In the event of a fall, the foot catch can quickly tighten, reducing the worker's fall speed and increasing worker safety.

[0033] In one specific embodiment, the foot pedal 1 is provided with a buckle structure to secure the worker's foot to the foot pedal 1. For example... Figure 1 As shown, specifically, the buckle structure includes an elastic band 19 and two buckle blocks 20. The two buckle blocks 20 are respectively disposed on both sides of the foot pedal 1, and the two ends of the elastic band 19 are respectively connected to the two buckle blocks 20.
