Description

Technical Field

[0001] This invention relates to the field of power maintenance tools, and in particular to an insulated operating rod auxiliary force-saving device. Background Technology

[0002] Insulated operating rods are basic insulating safety tools used for short-term operation or measurement of live equipment. They are commonly used tools by substation personnel and are frequently used in various operation and maintenance shutdown and power restoration operations.

[0003] When performing high-altitude operations (such as installing grounding wires at heights, handling foreign objects at heights, and testing for voltage), multiple sections of insulated operating rods are often required to be connected and used. For voltage levels of 330kV and 500kV, the length of high-voltage insulated operating rods can reach 8-10m.

[0004] Traditionally, insulated operating rods are operated manually by a single person. However, due to their weight, when connected to three or more sections, the rod head can become unstable and sway in the wind, making it difficult for the operator to lift and causing wobbling. This requires greater arm strength to control the rod and may even lead to accidental contact or impact with operating equipment, causing damage.

[0005] Manual operation of the insulated operating rod by a single person presents several inconveniences: When the rod is not fully erected, the operator uses both hands as a fulcrum to lift it upwards and the rear hand as the power arm to press down, overcoming the center of gravity of the rod and the working device at its top. However, the center of gravity of the rod and the working device is far from the fulcrum, generating a large torque even with a relatively small weight. Therefore, the force required to lift the rod and press down is several times the weight of the rod and the working device, resulting in high labor intensity. Furthermore, even before it is fully erected, both hands require considerable force, and the rod tends to shift with the hands. Swaying is inevitable; when the rod is not fully erected, it is difficult to rotate the insulating operating rod axially when both hands apply a large torque; when the insulating operating rod is erected, the operation time is usually long, and it is necessary to hold the insulating operating rod for a long time and precisely control the front, back and left and right positions of the top of the insulating operating rod, which is labor-intensive. When manually using a long and heavy insulating operating rod, it is often necessary to work in a coordinated manner by multiple people. However, by having multiple people squeeze together to operate the end of the high-voltage insulating operating rod, the space is crowded, and the high degree of cooperation required by the operators is poor. Summary of the Invention

[0006] In view of the problems existing in the above or prior art, the present invention is proposed.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] In a first aspect, the present invention provides the following technical solution: an insulated operating rod auxiliary force-saving device, comprising a rotatable clamp assembly that can rotate axially with the insulated operating rod and prevent axial sliding, a fulcrum assembly that supports the insulated operating rod and can rotate around a fulcrum, and a wearable assembly that fixes the fulcrum assembly to the operator's abdomen.

[0009] As a preferred embodiment of the insulated operating rod auxiliary force-saving device of the present invention, the insulated operating rod auxiliary force-saving device is characterized in that it includes a rotatable clamp assembly that can rotate axially with the insulated operating rod and prevent axial sliding, a fulcrum assembly that supports the insulated operating rod and can rotate around a fulcrum, and a wearable assembly that fixes the fulcrum assembly to the front abdomen of the operator.

[0010] As a preferred embodiment of the auxiliary force-saving device for the insulating operating rod of the present invention, the rotatable clamp assembly includes a rotator and at least one clamp; the clamp is fastened to the outside of the insulating operating rod, and the rotator slides axially; the rotator can rotate axially with the insulating operating rod, and the rotatable clamp assembly is movably connected to the axis of the insulating operating rod and rotates about the fulcrum assembly as the fulcrum axis.

[0011] As a preferred embodiment of the auxiliary force-saving device for the insulating operating rod of the present invention, the fulcrum assembly includes a fulcrum, a base disposed at one end of the fulcrum, a fulcrum clamp connector disposed on one side of the rotatable clamp assembly, and a wearable connector disposed on the outside of the base.

[0012] As a preferred embodiment of the insulated operating rod auxiliary force-saving device of the present invention, the wearable component includes a waist belt and a shoulder strap, both ends of the waist belt and the shoulder strap are provided with fulcrum connectors, and the fulcrum connectors are connected to the wearable connector.

[0013] As a preferred embodiment of the auxiliary force-saving device for the insulating operating rod of the present invention, at least one of the rotatable clamp assembly and the fulcrum assembly can be connected to the insulating operating rod by means of a snap-fit ​​or locking mechanism.

[0014] As a preferred embodiment of the insulated operating rod auxiliary labor-saving device of the present invention, the base of the fulcrum assembly is connected to the fulcrum on the outside, and the inner side of the base presents an arc shape that conforms to the outline of the human abdomen, and the inner side contacts the human abdomen during operation.

[0015] As a preferred embodiment of the auxiliary force-saving device for the insulating operating rod of the present invention, the connection between the fulcrum assembly and the rotatable clamp assembly is a flexible connection.

[0016] The fulcrum assembly is a rigid connection.

[0017] As a preferred embodiment of the auxiliary force-saving device for the insulating operating rod of the present invention, when the fulcrum assembly is configured as a flexible connection, the fulcrum assembly includes a fulcrum and a fulcrum clamp connector.

[0018] The fulcrum includes the plate fulcrum;

[0019] Pivot clamp connectors include flexible pivot clamp connectors;

[0020] The plate-type fulcrum has a hole facing outwards from the base; the flexible fulcrum clamp connector is a flexible connection device with both ends larger than the diameter of the hole in the plate-type fulcrum and the diameter of the fixed shaft hole of the rotatable clamp assembly. The flexible fulcrum clamp connector passes through the hole in the supporting plate-type fulcrum and the fixed shaft hole of the rotatable clamp assembly.

[0021] As a preferred embodiment of the auxiliary force-saving device for the insulating operating rod of the present invention, when the fulcrum assembly is set as a rigid connection, the fulcrum assembly includes a fulcrum and a fulcrum clamp connector.

[0022] The fulcrum includes bearing-type fulcrums and bearing-type fulcrum clamp connectors;

[0023] The bearing housing shaft of the bearing-type pivot faces outward from the base, and maintenance space is left between the bearing housing and the base plate. The bearing-type pivot clamp connector is inserted into the fixing shaft hole of the bearing-type pivot and the rotatable clamp assembly.

[0024] The beneficial effects of this invention are as follows: The auxiliary force-saving device of this invention is fixed at an arm's length distance from the bottom of the insulating operating rod. When the insulating operating rod is not fully upright, the fulcrum is supported by the strength of the waist and abdomen. The left and right hands are positioned about an arm's length away from the fulcrum, respectively, pushing and lifting the insulating operating rod. The resulting torque is greater than that of directly operating the insulating operating rod. Directly operating the insulating operating rod, with the front hand as the fulcrum and the rear hand acting as the power arm, requires significantly less force and has a much smaller lever arm than using the auxiliary force-saving device of this invention, resulting in better stability. The strength of the waist and abdomen is much greater than that of the hands. Using this invention, with the waist and abdomen supporting the fulcrum, the insulating operating rod is more stable. Furthermore, with both hands acting on the power arm, the stability is stronger than manually operating the insulating operating rod with only one hand acting as the power arm, allowing for flexible rotation. This invention includes a rotatable clamp assembly, allowing the insulating operating rod to rotate flexibly. When the insulating operating rod is not fully upright, using this invention, the strength of both hands is not very great; one hand can act on the power arm while the other hand operates the rotation. Manually operating the insulated control rod, with the front hand acting as a fulcrum and the rear hand as the power arm, requires considerable force while simultaneously ensuring the rod's rotation. This new system offers labor-saving benefits, reduces physical exertion, provides better stability, improves work efficiency, allows for flexible rotation, reduces physical exertion, and increases work efficiency. It also allows for flexible adjustment of the insulated control rod's position, especially beneficial for working at heights, reducing physical exertion and increasing work efficiency. Furthermore, it enables rapid assembly on-site. Attached Figure Description

Detailed Implementation

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1

[0036] Reference Figures 2-4This is the first embodiment of the present invention. This embodiment provides an insulated operating rod auxiliary force-saving device, which includes a rotatable clamp assembly 102 that can rotate axially with the insulated operating rod 101 and prevents axial sliding, a fulcrum assembly 103 that supports the insulated operating rod and can rotate around a fulcrum, and a wearable assembly 104 that fixes the fulcrum assembly 103 to the front abdomen of the operator.

[0037] The rotatable clamp assembly 102 includes a rotator 102a and at least one clamp 102b; the clamp 102b is fastened to the outside of the insulating operating rod 101, and the rotator 102a slides axially; the rotator 102a can rotate axially with the insulating operating rod 101, and the rotatable clamp assembly 102 is axially connected to the insulating operating rod 101 and rotates about the fulcrum assembly 103 as the fulcrum axis.

[0038] The fulcrum assembly 103 includes a fulcrum 103a, a base 103b disposed at one end of the fulcrum 103a, a fulcrum clamp connector 103c disposed on one side of the rotatable clamp assembly 102, and a wearable connector 103d disposed on the outside of the base 103b.

[0039] Wearable component 104 includes a waist belt 104a and a shoulder strap 104b, with pivot connectors 104c at both ends of the waist belt 104a and the shoulder strap 104b, and the pivot connectors 104c are connected to wearable connector 103d.

[0040] Ideally, before the insulated operating rod is fully erected, the fulcrum is supported by the strength of the waist and abdomen. The left and right hands are positioned about an arm's length away from the fulcrum, respectively, pushing and lifting the insulated operating rod. The torque generated is greater than that of directly operating the insulated operating rod. The front hand acts as the fulcrum, and the back hand acts as the power arm, which provides better stability. For the insulated operating rod to be stable, the force applied to both the fulcrum and the power arm must be sufficient and stable. The strength of the waist and abdomen is much greater than the strength of the hands. Supporting the fulcrum with the waist and abdomen can better stabilize the insulated operating rod. In addition, the stability is stronger than that of manually operating the insulated operating rod with only one hand as the power arm. At the same time, the insulated operating rod can also rotate flexibly.

[0043] The base 103b of the fulcrum assembly 103 is connected to the fulcrum 103a on the outside, and the inner side of the base 103b is an arc shape that conforms to the outline of the human abdomen. During operation, the inner side is in contact with the human abdomen.

[0044] The fulcrum assembly 103 is connected to the rotatable clamp assembly 102, and the fulcrum assembly 103 is a flexible connection.

[0045] The fulcrum assembly 103 is a rigid connection.

[0046] Preferably, the fulcrum components can be connected in various ways, which can greatly ensure the flexibility of the overall device, and at the same time, the connection method can be adjusted according to the actual site conditions, making the device more suitable for practical use.

When the fulcrum assembly 103 is configured as a flexible connection, the fulcrum assembly 103 includes a fulcrum 103a and a fulcrum clamp connector 103c.

[0049] Fulcrum 103a includes plate fulcrum 103a-1;

[0050] The fulcrum clamp connector 103c includes the flexible fulcrum clamp connector 103a-2;

[0051] The plate fulcrum 103a-1 has a hole facing outwards from the base 103b; the flexible fulcrum clamp connector 103a-2 is a flexible connection device with both ends larger than the hole diameter of the plate fulcrum 103a-1 and the fixed shaft hole diameter of the rotatable clamp assembly 102. The flexible fulcrum clamp connector 103a-2 passes through the hole of the supporting plate fulcrum 103a-1 and the fixed shaft hole of the rotatable clamp assembly 102.

[0052] When the fulcrum assembly 103 is configured as a rigid connection, the fulcrum assembly 103 includes a fulcrum 103a and a fulcrum clamp connector 103c.

[0053] The fulcrum 103a includes a bearing-type fulcrum 103a-11 and a bearing-type fulcrum clamp connector 103a-22;

[0054] The bearing housing shaft of the bearing type fulcrum 103a-11 faces the outside of the base 103b. There is maintenance space between the bearing housing and the base plate. The bearing type fulcrum clamp connector 103a-22 passes through the fixed shaft hole of the bearing type fulcrum 103a-11 and the rotatable clamp assembly 102.
