Description

Technical Field

[0001] The utility model relates to the technical field of operating rods, in particular to a multifunctional operating rod for a transformer substation. Background Art

[0002] The substation multi-function operating stick is an important tool used for various operation and maintenance tasks in the power system. This operating stick usually combines multiple functions to improve the efficiency and safety of substation operation and maintenance.

[0003] The multifunctional operating rod of a substation mainly consists of a support rod, a power rod (or working head), and other auxiliary components. The support rod is usually designed as a hollow circular tube, which has sufficient strength and rigidity to withstand various forces during operation.

[0004] Most existing substation operating rods use a threaded connection to secure the operating head. In this method, the bottom end of the operating head is typically provided with an internal thread, while the top end of the operating rod is provided with a matching external thread. During disassembly, the operator can use a tool (such as a wrench) to rotate the operating head counterclockwise to unscrew it from the operating rod. However, this disassembly method requires the operator to use tools, and the threaded connection wears over time, affecting the stability of the connection. Therefore, a multifunctional substation operating rod is proposed to address this problem. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a multifunctional operating rod for a substation. Through the provided limiting mechanism, the operating head can be quickly disassembled and replaced, and no contact is required when disassembling after use, thereby improving safety.

[0006] The technical solution for achieving the purpose of the utility model is: a multifunctional operating rod for a substation, comprising a supporting tube, an insulating sleeve fixedly connected to the surface of the supporting tube, a fixing plate fixedly connected to the inner wall of the supporting tube, a sliding hole penetrated through one side of the fixing plate, a sliding rod slidably connected to the inner wall of the sliding hole, a driving mechanism provided at the bottom end of the sliding rod, a push block fixedly connected to the top end of the sliding rod, a hollow plate fixedly connected to the inner wall of the supporting tube, two trapezoidal blocks slidingly provided on the lower surface of the hollow plate, and one side of each of the two trapezoidal blocks is fixedly connected to a U-shaped Rod, the surfaces of the two U-shaped rods are sleeved with spring three, the two ends of the two spring threes are fixedly connected to the opposite surfaces of the trapezoidal block and the inner wall of the support tube respectively, the ends of the two U-shaped rods away from the trapezoidal block are fixedly connected with a card block, the upper surface of the hollow plate is fixedly connected with multiple spring twos, the tops of the multiple spring twos are fixedly connected with the same reset plate, the surface of the reset plate is slidably connected to the inner wall of the support tube, and an operating head is provided on the upper surface of the reset plate, and two card slots are provided on the surface of the operating head, and the two card slots are respectively adapted to the corresponding two card blocks.

[0007] In some embodiments, the driving mechanism includes a slide plate that is slidably connected to the inner wall of the support tube, the upper surface of the slide plate is fixedly connected to the bottom end of the slide rod, the surface of the slide plate is fixedly connected to a push rod, the insulating sleeve and the surface of the support tube are provided with a same through groove, and the surface of the push rod is adapted to be slidably connected to the inner wall of the through groove.

[0008] In some embodiments, a spring 1 is sleeved on the surface of the slide rod, and two ends of the spring 1 are fixedly connected to the opposite surfaces of the fixed plate and the slide plate respectively.

[0009] In some embodiments, two sliding grooves are provided on the lower surface of the hollow plate, and the inner walls of the two sliding grooves are slidably connected with sliders, and the lower surfaces of the two sliders are respectively fixedly connected to the upper surfaces of the corresponding two trapezoidal blocks.

[0010] In some embodiments, two rectangular grooves are formed through the surface of the support tube, and inner walls of the two rectangular grooves are respectively adapted to be slidably connected with surfaces of the corresponding two clamping blocks.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] First, the utility model drives the slide plate to rise by the push rod, and then drives the slide bar to push the push block, and the push block rises and squeezes the two trapezoidal blocks, thereby realizing the opposite movement of the two trapezoidal blocks, and the opposite movement of the two trapezoidal blocks drives the two U-shaped rods to move synchronously, so that the two clamping blocks can be driven to slide by the action of the two U-shaped rods. When the clamping block slides, it can slip out of the clamping slot provided in the operating head. At this time, the operating head can pop out the operating head through the spring 2 provided under the reset plate, so that the clamping slot on the operating head is misaligned with the clamping block. At this time, release your finger, the slide bar will be reset under the action of the spring 1, and the operating head can pop out by itself, avoiding human contact, and preventing the operating head from being electrified after use, which affects the safety of personnel.

[0013] Secondly, when assembling the present invention, it is only necessary to insert the operating head into the support tube. The arc-shaped edge at the bottom of the operating head can squeeze the two blocks to expand. When the reset plate cannot be lowered, the operating head is then rotated until the slot and the block are matched to complete the limit.

[0014] The invention solves the problem that the thread disassembly method requires the operator to use tools for disassembly, and the thread connection method is worn due to the length of use time, which affects the connection stability. BRIEF DESCRIPTION OF THE DRAWINGS
