Description

Technical Field

[0001] The invention relates to the technical field of power-assisted tools, in particular to a multi-purpose overpressure anti-skid electric foot buckle. Background Art

[0002] my country has a large span from east to west and north to south, and the climate is very different. With the changes in seasonal climate, daily temperature and humidity, most areas often experience ice, frost, condensation and other phenomena on the distribution network cement towers, which leads to a significant reduction in the friction coefficient of the tower surface and makes climbing difficult. At present, the foot buckles that have been designed and applied all rely on gravity to generate resistance between the foot buckles and the towers to work, which has many shortcomings, mainly as follows:

[0003] First, its function is single and it can only be used as a foot tool for climbing poles; second, it is difficult to adjust the size of the buckle when using the existing foot buckle, which requires certain skills to control, and the fixing structure of the foot buckle and the foot is also relatively simple, with low reliability. The foot buckle frequently falls off and people slip during work, posing a great threat to the personal safety of operation and maintenance personnel; third, due to the limited resistance generated by gravity during work, especially when the friction coefficient of the pole tower surface is greatly reduced, the friction force is also greatly reduced, making it almost impossible to climb the pole, which poses a huge constraint and trouble to the operation and maintenance of overhead line equipment.

[0004] The existing Chinese patent "CN 108654020 B Electric foot buckle for overhead power transmission line tower" has a main friction rubber at the root of the foot buckle that can be extended and moved through a turbine worm structure. However, since the pole buckle ring is a semicircular structure as a whole and works through two corresponding points of mechanical contact, the semicircular structure is easily deformed by force, and has poor rigidity and strength, resulting in limited actual radial force, and thus limited actual working friction, which greatly reduces the actual application effect. Moreover, the turbine worm transmission structure can only have worm input and turbine output, and the main rubber at the root of the foot buckle is much less sensitive than ordinary foot buckles when taking into account the radial working pressure.

[0005] The existing Chinese patent "CN 217697839 U An electric foot buckle" can achieve stable and reliable adjustment of the buckle size, and there is no improvement in other directions. However, the outward shift of the center of gravity of the foot buckle further increases the risk of the foot buckle falling off during use, and there is no measure to suppress this risk.

[0006] The existing Chinese patent "CN 116688459 A A kind of anti-slip pole climbing foot buckle" has achieved stable and reliable adjustment of the buckle size, but its structural function is limited to adjusting the buckle size, and the flexibility of opening and closing is greatly reduced, affecting work efficiency; secondly, the shoe foot fixation has been improved to a certain extent, but in view of the serious outward shift of the center of gravity of the overall foot buckle, the tilting moment has increased significantly, resulting in the user being unable to control the horizontal angle of the foot buckle well; thirdly, the design essentially only increases the anti-slip effect surface, and the effect is very limited; fourthly, the clamping structure has poor adaptability to the pole diameter of the pole tower, and the stability is greatly reduced when facing the small pole diameter on the upper part of the conical cement pole.

[0007] The existing Chinese patent "CN 116747497 A A climbing foot buckle for power maintenance" has an emergency tightening and anti-falling device added to the anti-slip foot buckle, which has improved safety to a certain extent. However, when the overall mass of the foot buckle is greatly increased, the center of gravity offset torque increases greatly, and the simple threaded transmission cannot be tightened quickly when taking into account the motor torque and holding torque. The safety response speed will be affected to a certain extent, and the anti-falling effect of its structure will also be affected to a certain extent when facing equal-diameter cement poles; second, the size of the foot buckle ring cannot be adjusted, and the work adaptability and efficiency are greatly limited; third, the shoe and foot fixation has been improved to a certain extent, but its structural adaptability is poor.

[0008] Therefore, it is necessary to design a multi-purpose overpressure anti-skid electric foot buckle to solve the above-mentioned technical problems. Summary of the invention

[0009] In response to the above problems, the present application provides a multi-purpose over-pressure anti-slip electric foot buckle. When used as a foot buckle, the control logic is to open as soon as it is pressed. When the two foot buckle remote controls are pressed at the same time, the control is invalid. When used individually as a travel fall arrester as an ordinary foot buckle, it can also open as soon as it is pressed. Long pressing can adjust the size of the opening to prevent it from detaching from the pole body and causing an accident, and the overall control is safer and more reliable.

[0044] Compared with the prior art, the present invention provides a multi-purpose overpressure anti-skid electric foot buckle, which has the following beneficial effects:

[0045] 1. When the electric foot buckle in the present invention is used as a foot buckle, the control logic is to press and open. When the two foot buckle remote controls are pressed at the same time, the control is invalid. When the accompanying fall arrester as an ordinary foot buckle is used alone, it is also to press and open. Long press to adjust the size of the opening to prevent it from detaching from the rod body and causing an accident, and the overall control is safer and more reliable.

[0046] 2. The electric foot buckle of the present invention is brand new, efficient, practical, safe and reliable. The electric foot buckle uses the lever principle in the foot buckle opening and closing working mechanism, imitating the structure of the primate's hand to form a brand new foot buckle U-shaped opening and closing structure. The opening and closing are sensitive and can be achieved by remote control only. There is no need for personnel to master complex adjustment techniques and adjust the opening and closing size individually, which effectively improves work efficiency.

[0047] 3. In terms of applying working force, the electric foot buckle in the present invention relies on a T-threaded screw transmission structure and is powered by a planetary gear reduction motor with a braking function. The power end adopts a planetary gear reduction motor with a braking function, which can provide a strong rotational working torque; the T-thread used in the T-threaded screw has a higher transmission efficiency and strength than ordinary threads, and can reliably convert the torque of the planetary gear reduction motor with a braking function into a strong axial working force; in terms of working holding force, the T-thread transmission has a strong reverse working friction resistance, which cooperates with the brake device of the planetary gear reduction motor to provide a strong working holding force. At the same time, its power transmission structure combination can make the foot buckle generate a strong, precisely controllable vertical force and holding force in the radial direction of the pole tower that far exceeds the gravity of the staff, thereby generating super-strong working friction resistance, effectively suppressing the sliding and loosening between the foot buckle and the pole body.

[0048] 4. In terms of supporting stability, when the two L-shaped moving claws are tightened synchronously, the main friction surface rubber at the inner root of the U-shaped main arm of the electric foot buckle is used to realize three-point clamping force on the pole tower body. The triangle stability principle is used in combination with the wide and thick surface of the main friction surface rubber to provide a stable working force and effectively suppress the slippage of the foot buckle.

[0049] 5. The electric foot buckle in the present invention is based on the human foot fixing structure, and combines the ergonomic design of a new horizontally adjustable sole fixing structure and a shoe heel fixing contoured rear seat, so that the shoe foot is firmly fixed. At the same time, it has the design feature that the overall center of gravity of the foot buckle is close to the human foot. When the shoe foot is worn, the front and rear buckle binding straps can be used to quickly tighten and fix the staff's shoe foot, and the operator can flexibly control the electric foot buckle during the operation.

[0050] 6. The electric foot buckle of the present invention has a T-shaped threaded transmission structure with great reverse rotation resistance and a planetary gear reduction motor with a braking function in terms of top operation placement and auxiliary support function expansion, so it has a good controllable working holding force and does not need to be placed separately, and can be used as an effective auxiliary backup support point for the human body at high altitudes.

[0051] 7. The electric foot buckle of the present invention can effectively deal with the ice, frost, condensation and other conditions of the cement tower by its inherently generated powerful controllable radial force. If necessary, the wide curved rubber at the root can be replaced with metal spike-type curved rubber at any time to effectively deal with severe icing conditions. The overall performance is far superior to ordinary foot buckles.

[0052] 8. The electric foot buckle in the present invention has multi-purpose expansion functions. Through the control mode switching and the safety rope hanging buckle structure below, it can be used alone as a pole climbing accompanying fall arrester when personnel use ordinary foot buckles for operations, effectively ensuring the personal safety of personnel.

[0053] 9. The electric foot buckle of the present invention can be widely used in power distribution network, communication line operation and maintenance and other environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0091] See also Figure 1-Figure 33 The embodiment of the present invention provides a multi-purpose overpressure anti-skid electric foot buckle, which includes:

[0092] The pole tower clamping working unit 100 comprises a pole tower clamping structure basic unit 1100 which is clamped with the pole tower, and the pole tower clamping structure basic unit 1100 is installed on the pole tower clamping power basic unit 1200;

[0093] A shoe foot fixing unit 200, one end of which is fixedly arranged with the pole tower clamping structure basic unit 1100, and the other end of which is fixedly arranged with the pole tower clamping power basic unit 1200;

[0094] The power and control unit 300 includes a Bluetooth remote controller 45 connected to the wrist of a worker via a thin rope and a power auxiliary component fixedly arranged on the tower clamping working unit 100, and

[0095] The accompanying anti-fall auxiliary unit 400 is fixedly arranged on the pole tower clamping working unit 100 .

[0096] Based on the above scheme, the shoe foot fixing unit 200 is first adjusted and fixed to the heel of the staff. When the multi-purpose over-pressure anti-slip foot buckle is used as a climbing foot buckle, it is used in pairs, and the foot buckle working mode is switched to the foot buckle climbing mode through the electric energy and control unit 300. When climbing, the opening and closing signal of the pole tower clamping structure basic unit 1100 is transmitted to the electric energy auxiliary component one by one through the Bluetooth remote control 45 to adjust the opening and closing degree of the pole tower clamping structure basic unit 1100. When the control button of the Bluetooth remote control 45 is pressed at the same time, the operation is invalid; when the multi-purpose over-pressure anti-slip foot buckle is used as an accompanying fall arrester when climbing with an ordinary foot buckle, it is used individually, and the foot buckle working mode is switched to the accompanying fall arrest mode through the electric energy and control unit 300. The Bluetooth remote control 45 is used to transmit the opening and closing signal to the electric energy auxiliary component. During the climbing process, the button of the Bluetooth remote control 45 can be pressed and held to adjust the opening and closing degree of the pole tower clamping structure basic unit 1100 to adapt to the pole body of the pole tower.

[0097] On the basis of the above technical solution, the electric foot buckle can be widely used in power distribution network, communication line operation and maintenance and other environments. When the electric foot buckle is used as a foot buckle, the control logic is to press and open. When two Bluetooth remote controllers 45 are pressed at the same time, the control is invalid. When the accompanying fall arrester as an ordinary foot buckle is used alone, it is also to press and open. Long press to adjust the size of the opening to prevent it from detaching from the pole body and causing accidents. The overall control is safer and more reliable.
