Description

Technical Field

[0001] This invention relates to the field of electric power, and more specifically, to an auxiliary installation device for electric power engineering. Background Technology

[0002] Electricity is an energy source that uses electrical energy as its power source. Discovered in the 1870s, the discovery and application of electricity sparked the second industrial revolution and became one of the three technological revolutions that have occurred in the world since the 18th century. Since then, technology has changed people's lives. The large-scale power system that emerged in the 20th century is one of the most important achievements in the history of human engineering science. It is an electricity production and consumption system composed of power generation, transmission, transformation, distribution and consumption. It converts primary energy in nature into electricity through mechanical energy devices, and then supplies electricity to users through transmission, transformation and distribution. Cables are the basic elements of the power system. Cables can be laid in the air or buried underground. Underground cables are usually installed in underground tunnels and connected to the tunnels by power wells on the ground. People can enter the tunnels through the power wells to install and maintain the cables. To prevent people from accidentally falling into the power wells, power workers will install metal manhole covers on the top of the power wells.

[0003] Metal manhole covers need to be removed during the installation of new cables and the maintenance of old cables. Currently, power workers usually use a crowbar to insert into the pry hole on the metal manhole cover and pry up one side of the cover before manually moving it away. This is extremely time-consuming and laborious, and there is a risk of injury from falling objects. It is also inconvenient for power workers to put the metal manhole cover back in its original position. Therefore, there is an urgent need to design an auxiliary installation device for power engineering. Summary of the Invention

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of this invention are:

[0020] 1. The auxiliary support provides support to the disassembly and assembly mechanism, allowing it to suspend above the metal manhole cover. A reciprocating tilting force on the operating structure drives the rotator, which in turn drives the disassembly and assembly mechanism to lift the metal manhole cover. A positioning structure restricts the rotator, keeping the metal manhole cover suspended in the air. An offset mechanism allows power workers to quickly remove the metal manhole cover from the manhole for their work. The operation is time-saving and labor-saving, eliminating the need for manual handling of the manhole cover and the risk of injury from falling objects. This enhanced safety and practicality of the auxiliary installation equipment used in power engineering.

[0021] 2. The anti-movement mechanism can lock the offset mechanism, limiting the auxiliary support and ensuring the metal manhole cover is stably suspended in a fixed position without affecting power operations. This also allows the metal manhole cover to be stably suspended above the power well for installation. The reset device releases the rotator, allowing the disassembly and assembly mechanism to control the descent of the metal manhole cover for installation. The stationary structure applies a thrust to the straightening mechanism, which in turn applies a straightening force to the metal manhole cover, ensuring it descends horizontally and preventing installation difficulties caused by a vertical manhole cover. The installation process is simpler, eliminating the need for power workers to move the manhole cover, improving safety, and saving time and effort. This helps accelerate the completion of power work and enhances the practicality of this auxiliary installation equipment for power engineering. Attached Figure Description

It is used to apply a guiding force to the straightening mechanism 10 so that the straightening mechanism 10 will not deviate, and at the same time apply a thrust to the straightening mechanism 10 so that the straightening mechanism 10 can straighten the metal manhole cover.

[0044] Please see Figure 9-10 The straightening mechanism 10 also includes a straightening ring 102, which is slidably inserted inside the straightening sliding member 101. A straightening tube 103 is fixedly connected to the bottom surface of the straightening ring 102.

It is used to straighten the metal manhole cover so that the metal manhole cover is suspended in a horizontal state, which facilitates subsequent installation.

[0045] Working principle:

[0046] First, hook the removal hook 25 into the pry hole on the metal manhole cover. Then, apply downward pressure to the soft sleeve 36. Next, the soft sleeve 36 applies downward pressure to the operating rod 33 through the reinforcing crossbar 35. Then, the operating rod 33 rotates the operating cylinder 31 counterclockwise. Then, the operating cylinder 31 rotates the removal shaft 22 counterclockwise through the one-way meshing between the inclined column head 44 and the ratchet 47. Then, the removal shaft 22 rotates the removal reel 23 counterclockwise. Then, the removal line 24 is wound around the outside of the removal reel 23. Then, the removal line 24 lifts the metal manhole cover upward through the removal hook 25. Then, the metal manhole cover contacts the straightening crossbar 104. Then, the metal manhole cover presses on the bottom surface of the straightening crossbar 104. The straightening cross 104, straightening tube 103, straightening ring 102, and straightening sliding member 101 apply an upward thrust to the stationary slide rod 94. The stationary slide rod 94 then moves the stationary piston 93 upwards. The stationary piston 93 then compresses the stationary spring 92, causing the spring to compress elastically and increase its elastic potential energy. This increases the pressure of the straightening cross 104 on the metal manhole cover, causing it to become horizontal under this pressure. The operating rod 33 then contacts the bottom surface of the inner cavity of the flipping through hole 34, and the soft sleeve 36 is released. The operating cylinder 31 then rotates clockwise with the operating rod 33 under the elastic tension of the return spring 32. Simultaneously, the positioning plug 53, under the elastic force of the positioning spring 52, compresses the positioning pin 54. On the ratchet 47, the one-way meshing between the ratchet 47 and the positioning pin 54 fixes the disassembly shaft 22, then the disassembly reel 23 is fixed, and the metal manhole cover is fixed and suspended in the air. Next, the operating rod 33 contacts the top surface of the inner cavity of the flipping through hole 34. At this time, the operating rod 33 flips upward to the dead point position, and then downward pressure is applied to the soft sleeve 36 again. This is repeated to gradually increase the height of the metal manhole cover until the height of the metal manhole cover is higher than the height of the top surface of the auxiliary lead plate 11. Then, the downward pressure is stopped on the soft sleeve 36, and then downward pressure is applied to the anti-movement pressure rod 85. Then, the anti-movement pressure rod 85 is pulled out from the corresponding anti-movement opening slot 86 through the anti-movement disc 83 with the anti-movement plate 84. Then, the offset disc 7... 4 is released, and then a counterclockwise thrust is applied to the auxiliary arm plate 14. Next, the auxiliary arm plate 14, via the disassembly and assembly mechanism 2, rotates 180 degrees counterclockwise around the auxiliary support 13 as its central axis. Then, the auxiliary arm plate 14 rotates with the auxiliary support 13, and the auxiliary support 13 rotates synchronously with the offset disc 74. Then, the offset vertical bar 76 separates from the rear stop bar 77 and contacts the front stop bar 78. At this time, the offset disc 74 rotates 180 degrees, and the anti-motion plate 84 aligns with another anti-motion opening slot 86. Then, the anti-motion pressure rod 85 is released. Afterwards, the anti-motion disc 83, under the action of the anti-motion spring 82, moves upward with the anti-motion plate 84 and the anti-motion pressure rod 85. Then, the anti-motion plate 84 inserts into the corresponding anti-motion opening slot 86, locking the offset disc 74.The metal manhole cover is then fixed in its suspended position. At this point, the metal manhole cover moves away from the power well and is positioned above the auxiliary lead plate 11. Then, the power worker enters the power well to install and maintain cables. After the work is completed, the power worker exits the power well and applies pressure to the anti-movement pressure bar 85, causing the offset disc 74 to rotate. The offset disc 74 then rotates clockwise under the torque of the torsion spring 75. The offset disc 74, through the auxiliary support 13, auxiliary arm plate 14, and disassembly / assembly mechanism 2, rotates the metal manhole cover clockwise in a circular motion until the offset vertical bar 76 contacts the rear stop bar 77. The anti-movement pressure bar 85 is then released, and the anti-movement plate 84, under the elastic force of the anti-movement spring 82, inserts into the anti-movement opening slot 86, fixing the metal manhole cover in its suspended position. At this point, the metal manhole cover is suspended above the power well. Next, a leftward push is applied to the U-shaped reset handle 67. The U-shaped reset handle 67 then passes through the reset collar 66, reset wing 65, and reset plunger. Pull the reset line 64, then the reset line 64 pulls the tracing plunger 43 to the left. Next, the tracing plunger 43, along with the inclined plunger head 44, moves to the left. Simultaneously, the tracing plunger 43 applies a leftward thrust to the linkage bar 55 via the tracing pin 45. Then, the linkage bar 55, along with the positioning plunger 53 and positioning pin 54, moves to the left. Finally, the inclined plunger head 44 and positioning pin 54 separate from the ratchet 47, and the disassembly reel 23 is released. Afterward, the metal manhole cover is re-installed. Under the action of force, it moves downward and pulls the disassembly line 24 through the disassembly hook 25, releasing the disassembly line 24 from the outside of the disassembly line reel 23. At the same time, the stationary piston 93, under the action of the stationary spring 92, moves downward through the stationary slide rod 94, carrying the straightening mechanism 10, ensuring that the metal manhole cover moves downward in a horizontal state. Then, the metal manhole cover is placed in the power well. Next, the U-shaped reset handle 67 is released, and then the inclined column head 44 and the positioning pin 54 engage with the ratchet 47 in one direction, thus completing the process.
