Description

Technical Field

[0001] The utility model relates to the field of switch cabinet accessory operating devices, in particular to a portable multifunctional ratchet operating handle. Background Art

[0002] At present, the switch cabinets used in the power supply and distribution system of urban rail transit come from different manufacturers. Each manufacturer has its own model of switch cabinet products. The operating holes on different switch cabinets are also different. There are more than a dozen types of switch cabinet operating handles. There are many operating task processes involving the power supply and distribution switch cabinets, and the models of switches vary greatly.

[0003] In actual construction and the increasingly heavy operation and maintenance work, this single-function operating handle has the following disadvantages: First, a switch cabinet is equipped with one or more single-function operating handles. When performing switching operations, operators often need to carry multiple single-function operating handles with them, which seriously increases the number of tools used; second, since the operating handles are mostly "U"-shaped and "Z"-shaped designs, they are not in line with the force characteristics of the human body. In addition, the perception of the control of the equipment is reduced after wearing insulating protective equipment, and the switching operation becomes particularly difficult, resulting in inconvenient operation and easy damage to the components in the switch cabinet, which greatly reduces work efficiency; third, the numerous operating handles not only increase the amount of daily sorting and maintenance tasks, but also occupy the company's storage space for tools, resulting in a waste of space costs. Utility Model Content

[0028] This embodiment provides a portable multifunctional ratchet operating handle, such as Figure 1-4 As shown, it includes: a handle bar 1, a ratchet device 7;

[0029] Among them, the handle rod 1 is integrated with the ratchet device 7, and the overall design is T-shaped. A universal handle 2 is provided at one end of the handle rod 1. The universal handle 2 can set the operating angle arbitrarily according to the operating requirements of different types of switch cabinets, which greatly reduces the labor intensity of workers and effectively solves the problem of low work efficiency caused by the need for operators to carry multiple operating handles at the same time to complete the operation of switch cabinets of different structural types in the prior art; the handle rod 1 and the ratchet device 7 are connected and fixed together by a threaded plug 3, a pin shaft 4, and a shoulder screw 5. The shoulder screw 5 is used as a fastener to connect and fix the handle rod 1 and the ratchet device 7. After installation, the column part can be used as an axis function, and move relative to the connected parts to realize the coaxial output of the operating handle.

[0030] The pin shaft 4 serves as a fixed connection, facilitating the disassembly and replacement of the handle bar 1 and the ratchet device 7 .

[0031] In this embodiment, the ratchet device 7 is provided with a matching positioning switch 6. The ratchet device 7 is provided with a matching positioning switch 6. By turning the positioning switch 6, the forward rotation, reverse rotation and locking functions can be realized, and the operation can be performed according to the operation task.

[0032] Preferably, the front end of the ratchet device 7 is connected to a locking threaded head 8, and the locking threaded head 8 is connected to a chuck 9, which can lock the chuck 9 to fix the connecting head 10. The chuck 9 is provided with a hexagonal connecting hole groove 11. The connecting head 10 is provided with three types, and one end of the connecting head 10 is a hexagonal column head of the same size as the hexagonal connecting hole groove 11.

[0033] Furthermore, by replacing different types of connectors 10, switch operations of different types of structures of AC 35kV switch cabinets, AC 400V switch cabinets, and DC 1500V switch cabinets can be realized. The AC 35kV switch cabinet connector 10 can realize the on-site operation of the disconnector and the earthing switch of the AC 35kV switch cabinet. After inserting the connector 10 into the operating handle, the positioning switch 6 is moved according to the inverted direction of the switch cabinet, and the linear handle of the operating handle is used to realize the position conversion of the disconnector and the earthing switch; the AC 400V switch cabinet connector can realize the AC 400V incoming line disconnection. The 1500V DC switch cabinet connector can realize the on-site operation of the working position, test position and isolation position of the DC 1500V circuit breaker trolley. After inserting the connector 10 into the operating handle, the positioning switch 6 is bent according to the inverted cutting direction of the circuit breaker, and the universal handle or the linear handle on the operating handle is used to realize the operation of the working position, test position and isolation position of the circuit breaker. The 1500V DC switch cabinet connector can realize the on-site operation of the working position, test position and isolation position of the DC 1500V circuit breaker trolley. After inserting the connector 10 into the operating handle, the positioning switch 6 is bent according to the inverted cutting direction of the circuit breaker trolley, and the universal handle 2 on the operating handle is used to realize the operation of the working position, test position and isolation position of the circuit breaker.

[0034] When it is necessary to use the operating handle to perform a switching operation, insert the corresponding connector 10 into the hexagonal connecting hole 11 of the operating handle, and then turn the positioning switch 6 to adjust the ratchet device 7 to a certain degree of forward and reverse rotation according to the actual working environment, so that the operating handle can be used to drive the connector 10 to rotate, so as to realize on-site operation of the AC 35kV switchgear, AC 400V switchgear, and DC 1500V switchgear; it effectively solves the problem in the prior art that operators need to carry multiple operating handles at the same time to operate switches of different structures on different types of switchgear, resulting in low work efficiency. The portable multifunctional ratchet operating handle has a reasonable structure, is easy to use, and conforms to ergonomic characteristics, improves the switching efficiency and saves labor costs. It can be used with different connectors according to the use requirements to realize the operation tasks of power supply and distribution switchgear of different types and models, and integrates the functional characteristics of multiple single-function operating handles, which greatly facilitates daily power outage operations. At the same time, due to the unique characteristics of the single connector application switch, it can effectively avoid the possibility of misoperation, ensure operational safety, greatly shorten the power outage time, improve the work efficiency of the staff, and facilitate maintenance work.
