Description

Technical Field

[0001] This utility model relates to an auxiliary device for the maintenance of power facilities, specifically an auxiliary device for climbing utility poles, and more specifically a pole climbing machine. Background Technology

[0002] When performing maintenance, repair, and emergency repairs on power distribution lines, workers need to climb utility poles to inspect, tighten, or replace components such as wires, insulators, and clamps. Currently, the commonly used pole-climbing aid is a wearable foot strap (a semi-circular iron tool). Workers wear the foot strap on their feet, secure a safety belt around their waist around the pole, and then climb the pole by alternately stepping on the foot strap. This method has the following drawbacks: it requires high physical fitness, good stamina, climbing skills, and good coordination; it carries safety risks, as the worker risks slipping if the foot strap falls off or deforms; and once at the top of the pole, the worker needs to continuously exert leg strength to remain standing, resulting in significant physical exertion. Utility Model Content

[0003] This invention provides a pole climbing machine, which aims to overcome the above-mentioned shortcomings of the prior art when using foot buckles as an auxiliary pole climbing tool.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A pole climbing machine includes a seat, a drive motor, a battery compartment, an upper support arm, an upper grab arm, and lower support legs. The drive motor and the battery compartment are fixedly installed inside the seat. The drive motor is electrically connected to an operation panel and a battery located in the battery compartment. The upper support arm and the upper grab arm are fixed to the upper front side of the seat and extend obliquely upward. A first rotating shaft with a drive wheel is connected between the upper ends of the upper support arm and the upper grab arm. A transmission mechanism is provided inside the upper support arm. The drive motor drives the drive wheel to rotate through the transmission mechanism. A second pivot with a driven wheel is connected between the middle of the upper support arm and the upper arm. The upper end of the lower support leg is fixedly connected to the front of the seat. The lower support leg extends diagonally downward and its lower end is connected to a third pivot with a lower support wheel via a fork-shaped connector. Foot pedals are formed on both sides of the fork-shaped connector. A manual brake assembly is provided between the first pivot and the second pivot. The upper arm includes a first movable section and a second movable section that are locked together by a locking member. When the locking member is unlocked, the upper arm can open the power supply rod from the first movable section and the second movable section to enter the opening between the driving wheel and the driven wheel.

[0005] Based on the above technical solution, the present invention can be further improved as follows.

[0006] Furthermore, the two ends of the first and second rotating shafts are respectively rotatably connected to the upper support arm and the upper clamping arm via bearing components. The transmission mechanism includes a synchronous belt and a gear set, and the drive motor drives the first rotating shaft to rotate via the synchronous belt and the gear set.

[0007] Furthermore, the manual brake assembly includes a handbrake lever rotatably connected to the upper support arm, a first brake component sleeved on the first rotating shaft, and a second brake component sleeved on the second rotating shaft. The handbrake lever is respectively connected to the first brake component and the second brake component via a first connecting rod and a second connecting rod. The first brake component and the second brake component are respectively provided with brake pads for pressing against the outer wall of the utility pole. When the handbrake lever is manually pulled, the first brake component and the second brake component rotate and the corresponding brake pads clamp the utility pole from the front and rear sides.

[0008] Furthermore, the first brake component and the second brake component have the same structure, each including a sleeve, a radial connecting rod, and a U-shaped mounting component. The radial connecting rod is fixed radially to the outer wall of one end of the sleeve. The sleeve is sleeved on the first rotating shaft or the second rotating shaft. One end of the mounting component is fixedly connected to the outer wall of the other end of the sleeve. The other end of the mounting component passes around the driving wheel or the driven wheel and is rotatably connected to the corresponding first rotating shaft or the second rotating shaft. The brake pad is fixed on the mounting component.

[0009] Furthermore, the upper arm also includes a fixed section, which is inclined and its lower end is fixedly connected to the upper front part of the stool. The upper end of the fixed section is rotatably connected to the lower end of the second movable section. The upper end of the second movable section is connected to the lower end of the first movable section through the locking member. The upper end of the first movable section is rotatably connected to the first rotating shaft.

[0010] Furthermore, the locking element is a bolt or a pin.

[0011] Furthermore, it also includes a hand handle, which is fixed by a support extending upward from the upper end of the upper arm.

[0012] Furthermore, a status indicator panel is fixed on the handrail, and the status indicator panel is electrically connected to the operation panel.

[0013] Furthermore, the control panel is fixed to one side of the middle part of the upper support arm, and the seat is equipped with a backrest and a safety belt.

[0014] Furthermore, the walls of the driving wheel, driven wheel, and lower support wheel are all configured as arc-shaped structures that gradually curve from both ends to the middle to fit against the outer wall of the utility pole.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Powered by a battery-driven motor, the machine rotates the drive wheel via a transmission mechanism within the upper support arm. With the operator seated, the weight of the operator and the machine itself causes the drive and driven wheels to grip the utility pole from both sides. The rotation of the drive wheel causes the machine to lift the operator up and down the pole simultaneously. Climbing is easy; the operator, seated, can easily inspect or replace electrical equipment at the top of the pole, ensuring good safety. A manual brake allows the operator to stop the machine in an emergency. The machine also features a lower support wheel; this ensures a more stable and safer ascent and descent by gripping the pole through the drive, driven, and lower support wheels.

[0025] The technical solution provided by this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] In the description of this utility model, if terms such as "upper", "lower", "left", "right", "top", "bottom", "inner", and "outer" are used to indicate the orientation or positional relationship, the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] like Figures 1 to 6 As shown, this utility model provides a pole climbing machine, which includes a seat 1, a drive motor 2, a battery compartment 3, an upper support arm 4, an upper grab arm 5, and a lower support leg 6. The drive motor 2 and the battery compartment 3 are fixedly installed inside the seat 1. The drive motor 2 is electrically connected to an operation panel 7 and a battery located in the battery compartment 3. The upper support arm 4 and the upper grab arm 5 are fixed to the upper front side of the seat 1 and extend obliquely upward. A first rotating shaft 9 with a drive wheel 8 is connected between the upper ends of the upper support arm 4 and the upper grab arm 5. A transmission mechanism is provided inside the upper support arm 4. The drive motor 2 drives the drive wheel 8 to rotate through the transmission mechanism. The middle part of the upper support arm 4 and the upper grab arm 5 A second rotating shaft 11 with a driven wheel 10 is connected between the two shafts. The upper end of the lower support leg 6 is fixedly connected to the front of the seat 1. The lower support leg 6 extends diagonally downward and its lower end is connected to a third rotating shaft with a lower support wheel 13 through a fork-shaped connector 12. Foot pedals 14 are formed on both sides of the fork-shaped connector 12. A manual brake assembly is provided between the first rotating shaft 9 and the second rotating shaft 11. The upper arm 5 includes a first movable section 16 and a second movable section 17 that are locked together by a locking member 15. When the locking member 15 is unlocked, the upper arm 5 can open the power supply rod from the first movable section 16 and the second movable section 17 to enter the opening between the driving wheel 8 and the driven wheel 10.

[0028] Understandably, the first and second movable sections of the upper arm can open an opening after the locking mechanism is unlocked (e.g., bolts are removed or pins are pulled out). This opening allows the pole climber to be hung on the utility pole, allowing the pole to enter between the drive and driven wheels, while the lower support wheel also abuts against the pole. The control panel has up, down, and lock (stop) buttons, which can be mechanical or touch-sensitive. Through the control panel, the operator can control the drive motor to rotate forward, reverse, or stop. When the motor stops, the pole climber can stably remain on the utility pole. This can be achieved either by the gear and screw mechanism in the transmission system providing holding torque, or by the excitation coil in the motor generating a static magnetic field to lock the rotor; the former is preferred.

[0029] In one embodiment of this utility model, the two ends of the first rotating shaft 9 and the second rotating shaft 11 are respectively rotatably connected to the upper support arm 4 and the upper clamping arm 5 through bearing components. The transmission mechanism includes a synchronous belt and a gear set. The drive motor 2 drives the first rotating shaft 9 to rotate through the synchronous belt and the gear set.

[0030] It should be noted that the transmission mechanism is not limited to the combination of synchronous belt and gear set. Any transmission structure in the prior art that can drive the motor to rotate the shaft located at a certain distance and automatically lock the shaft when the motor stops can be used here. This transmission mechanism is a structure well known to those skilled in the art and will not be described in detail here.

[0031] In one embodiment of this utility model, the manual brake assembly includes a handbrake lever rotatably connected to the upper support arm 4, a first brake component 20 sleeved on the first rotating shaft 9, and a second brake component 21 sleeved on the second rotating shaft 11. The handbrake lever is respectively connected to the first brake component 20 and the second brake component 21 via a first connecting rod 23 and a second connecting rod 24. The first brake component 20 and the second brake component 21 are respectively provided with brake pads 22 for pressing against the outer wall of the utility pole. When the handbrake lever is manually pulled, the first brake component 20 and the second brake component 21 rotate and cause the corresponding brake pads 22 to clamp the utility pole from the front and rear sides.

[0032] It should be noted that the brake pads can be rubber blocks; in addition, if necessary, those skilled in the art can also install a tension holding mechanism such as a spring on the upper support arm, so that when braking is required, the operator can pull the handbrake to the correct position and hold the handbrake lever by the spring.

[0033] In one embodiment of this utility model, the first brake component 20 and the second brake component 21 have the same structure, each including a sleeve, a radial connecting rod and a U-shaped mounting component. The radial connecting rod is fixed radially to the outer wall of one end of the sleeve. The sleeve is sleeved on the first rotating shaft 9 or the second rotating shaft 11. One end of the mounting component is fixedly connected to the outer wall of the other end of the sleeve. The other end of the mounting component passes around the driving wheel 8 or the driven wheel 10 and is rotatably connected to the corresponding first rotating shaft 9 or the second rotating shaft 11. The brake pad 22 is fixed on the mounting component.

[0034] It should be noted that the first brake component and the second brake component are rotatably connected to the first rotating shaft and the second rotating shaft, respectively, and both brake components are made of stainless steel.

[0035] In one embodiment of this utility model, the upper arm 5 further includes a fixed section 18, the fixed section 18 is inclined and its lower end is fixedly connected to the upper front part of the seat 1, the upper end of the fixed section 18 is rotatably connected to the lower end of the second movable section 17, the upper end of the second movable section 17 is connected to the lower end of the first movable section 16 through the locking member 15, and the upper end of the first movable section 16 is rotatably connected to the first rotating shaft 9.

[0036] In one embodiment of this utility model, the locking member 15 is a bolt or a pin.

[0037] Understandably, the connection between the first and second movable sections is provided with a hole structure for the locking element to be screwed in or inserted.

[0038] In one embodiment of the present invention, a hand handle 25 is also included, which is fixed by a support member 27 extending upward from the upper end of the upper support arm 4.

[0039] It should be noted that the handrail has two gripping parts on the left and right, and the gripping parts are covered with anti-slip rubber.

[0040] In one embodiment of the present invention, a status indicator panel 26 is fixed on the hand handle 25, and the status indicator panel 26 is electrically connected to the operation panel 7.

[0041] It should be noted that the status indicator panel can display the current working status of the pole climbing machine, such as ascending, descending, or stopped, and can also display the ascending speed or descending speed.

[0042] In one embodiment of the present invention, the operation panel 7 is fixed to one side of the middle part of the upper support arm 4, and the seat 1 is provided with a backrest 28 and a safety belt.

[0043] Understandably, installing safety belts and backrests on the seats can significantly improve the safety of using the pole climbing machine.

[0044] In one embodiment of this utility model, the wheel walls of the driving wheel 8, the driven wheel 10 and the lower support wheel 13 are all configured as arc-shaped structures that gradually curve from both ends to the middle so as to fit against the outer wall of the utility pole.

[0045] It should be noted that, as Figure 1 As shown, the driving wheel, driven wheel, and lower support wheel are all designed as two truncated cones connected coaxially by their narrow ends. In other words, the wheel walls are all designed as arc-shaped structures that gradually curve from both ends to the middle. This design increases the contact area between the wheel walls and the utility pole, thereby ensuring that the pole climbing machine can rise and fall along the utility pole more effectively.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
