Description

Technical Field

[0001] The invention relates to the technical field of electric power repair tools, and in particular to an auxiliary labor-saving device for an insulating operating rod. Background Art

[0002] The insulated operating rod is a basic insulating safety tool used to operate or measure live equipment for a short period of time. It is a common work tool used by substation personnel and is often used in various maintenance and power outage and transmission operations. It is used very frequently.

[0003] When working at height (such as hanging ground wires, handling foreign objects at height, testing electricity, etc.), it is often necessary to connect multiple sections of insulating operating rods. For 330kv and 500kv voltage levels, the length of the high-voltage insulating operating rod can reach 8-10m.

[0004] The traditional method of using the insulating operating rod is manual operation by one person. However, since the insulating operating rod has a certain weight, when it is connected to three or more sections, the head of the insulating operating rod will swing unsteadily due to the wind, making it difficult for the operator to lift it and it will shake, requiring greater arm strength for the operator to control the insulating operating rod, and it may even accidentally touch or hit the equipment in operation, causing damage to the equipment.

[0005] There are still many inconveniences in manually operating the insulating operating rod by one person: when the insulating operating rod has not been fully erected, the operator's front hand lifts up as a fulcrum and the back hand presses down as a power arm to overcome the center of gravity of the insulating operating rod and the working device on the top of the pole, but the center of gravity of the insulating operating rod and the working device on the top of the pole is far away from the fulcrum. Even if the weight is not large, a large torque will be generated. Therefore, the force of lifting with the front hand and pressing down with the back hand requires several times the weight of the insulating operating rod and the working device on the top of the pole, and the labor intensity is relatively high. When the insulating operating rod has not been fully erected, both hands require greater strength, and the pole will be easily moved. Shaking is inevitable; when it is not fully erected, it is difficult to operate the axial rotation of the insulating operating rod when both hands provide torque with great force; when the insulating operating rod is erected for operation, the operation time is usually long, and the insulating operating rod is lifted for a long time, and the front, back, left and right position of the top of the insulating operating rod must be carefully controlled, which is labor-intensive. When manually using a longer and heavier insulating operating rod, it is often necessary for multiple people to work in a collaborative manner. However, when multiple people squeeze together to operate the end of the high-voltage insulating operating rod, the site is crowded, and the operator needs to cooperate highly, and the assistance effect is poor. Summary of the invention

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

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] In a first aspect, the present invention provides the following technical solutions: a heat dissipation device for a distribution automation intelligent terminal box, comprising a rotatable clamp assembly that can rotate axially with an insulating operating rod and prevent axial sliding, a fulcrum assembly that supports the insulating operating rod and can rotate around a fulcrum, and a wearable assembly that fixes the fulcrum assembly on the front abdomen of an operator.

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

[0010] As a preferred solution of the insulating operating rod auxiliary labor-saving device 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 insulating operating rod shaft and rotates with the fulcrum assembly as the fulcrum axis.

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

[0012] As a preferred solution of the insulating operating rod auxiliary labor-saving device of the present invention, the wearing component includes a waist belt and a shoulder strap, and fulcrum connectors are provided at both ends of the waist belt and the shoulder strap, and the fulcrum connector is connected to the wearing connector.

[0013] As a preferred solution of the auxiliary labor-saving device of 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 a snap or lock method.

[0014] As a preferred solution of the insulating 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 outer contour of the human abdomen, and the inner side contacts the human abdomen during operation.

[0015] As a preferred solution of the auxiliary labor-saving device of the insulating operating rod of the present invention, the connection between the fulcrum component and the rotatable clamp component is a flexible connection;

[0016] The fulcrum assembly is a rigid connection.

[0017] As a preferred solution of the auxiliary labor-saving device of the insulating operating rod of the present invention, when the fulcrum assembly is set as a flexible connection, the fulcrum assembly includes a fulcrum and a fulcrum clamp connector;

[0018] The fulcrum includes a plate fulcrum;

[0019] The fulcrum clamp connector includes a flexible fulcrum clamp connector;

[0020] The plate-type fulcrum is provided with a hole facing the outside of the base; the flexible fulcrum clamp connector is a flexible connection device with two ends having dimensions larger than the aperture of the plate-type fulcrum opening and the aperture of the fixed shaft of the rotatable clamp assembly; the flexible fulcrum clamp connector passes through the supporting plate-type fulcrum hole and the fixed shaft hole of the rotatable clamp assembly.

[0021] As a preferred solution of the auxiliary labor-saving device of 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 a bearing-type fulcrum and a bearing-type fulcrum clamp connector;

[0024] The present invention has the beneficial effect of fixing the auxiliary labor-saving device of the present invention at a position one arm away from the bottom of the insulating operating rod. When the insulating operating rod has not been fully erected, the fulcrum is supported by the strength of the waist and abdomen. The left and right hands are at the positions of one arm of the insulating operating rod at both ends of the fulcrum, respectively, and the force is pushed and lifted, and the torque generated is greater than that of directly operating the insulating operating rod. Directly operating the insulating operating rod, the front hand acts as the fulcrum, and the back hand acts on the power arm. The strength and the force arm are much smaller than those of the auxiliary labor-saving device of the present invention, and have better stabilization function. The waist and abdomen strength is much greater than the strength of the hands. The present invention uses the waist and abdomen to support the fulcrum, which can better stabilize the insulating operating rod. In addition, two hands act on the power arm, and the stabilization ability is also stronger than the manual operation of the insulating operating rod with one hand as the power arm, which can flexibly rotate. The present invention has a rotatable clamp assembly, and the insulating operating rod can flexibly rotate. When the insulating operating rod has not been fully erected, the present invention is adopted, and the strength of both hands is not very large, and one hand can act on the power arm, and the other hand can operate the rotation. When manually operating the insulating operating rod, the front hand is used as the fulcrum and the back hand acts as the power arm. It is quite difficult to rotate the insulating operating rod when a large force is required. It has the effect of saving labor, reducing labor intensity, having better stability function, improving work efficiency, and can rotate flexibly, reducing labor intensity, improving work efficiency, and can flexibly adjust the state of the insulating operating rod, especially when working at high places, which can reduce labor intensity, improve work efficiency, and can be quickly assembled on the job site.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present 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 term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[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 with the fulcrum assembly 103 as the fulcrum axis.

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

The torque generated is greater than that of directly operating the insulating operating rod. The front hand acts as the fulcrum and the back hand acts as the power arm, which has a better stabilizing function. To stabilize the insulating operating rod, the strength acting on 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 insulating operating rod.

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

[0046] Preferably, the fulcrum assembly can be connected in a variety of forms, which can greatly ensure the flexibility of the overall device. At the same time, the connection method can be adjusted according to the actual situation on site, making the device more suitable for practical use.
