Abstract
Description
Technical Field
[0001] This utility model relates to the field of climbing equipment technology, and in particular to a support mechanism and an auxiliary device for upper and lower tailwater pipes. Background Technology
[0002] The tailrace of a hydroelectric power station is a pipe structure connecting the turbine runner outlet to the tailrace. Its main function is to recover the energy of the water flow at the turbine runner outlet, thereby improving the turbine's efficiency. Therefore, regular maintenance of its internal equipment is necessary. However, the bottom of the tailrace is more than 20 meters above the ground, and the lower part of the cone gate leading into the tailrace lacks a foothold. Maintenance personnel need at least one assistant to work with a self-climbing device to move the tailrace up and down, which increases labor costs and introduces the risk of secondary falls, hindering safety and convenience during maintenance. Utility Model Content
[0003] Therefore, the technical problem to be solved by this utility model is that it is inconvenient for existing maintenance personnel to carry out maintenance on the internal devices of the tailwater pipe alone, and auxiliary personnel are needed to complete the upper and lower parts of the tailwater pipe.
[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a support mechanism, which includes a support component, including a support part and an installation part connected to a tapered gate, wherein a connector is provided between the installation part and the support part, the support part can be close to or away from the installation part along the vertical direction of the tapered gate, and is perforated and disposed on the installation part, and an abutment rod is provided in the perforation to increase the contact area between the installation part and the tapered gate.
[0005] As a preferred embodiment of the support mechanism of this utility model, the mounting part includes parallel connecting rods and a U-shaped plate fixedly connected to each connecting rod, wherein a through hole is provided on the connecting rod at a position away from the U-shaped plate, and the lower part of the U-shaped plate is provided with a mounting groove for connecting to the tapered tube door.
[0006] As a preferred embodiment of the support mechanism of this utility model, both ends of the abutment rod are through holes, and the abutment rod is provided with abutment threads that are threadedly connected to the through holes.
[0007] As a preferred embodiment of the support mechanism of this utility model, the connecting member includes a connecting plate one that is rotatably connected to the support part and a connecting plate two that is fixedly connected to the mounting part, and the connecting plate one and the connecting plate two are arranged in parallel.
[0008] As a preferred embodiment of the support mechanism of this utility model, the connecting plate one and the connecting plate two are respectively provided with corresponding adjustment holes one and two, and the adjustment holes are provided with adjustment bolts that are threadedly connected to the adjustment holes two.
[0009] As a preferred embodiment of the support mechanism of this utility model, a contact protrusion is provided below the support part and near the rotating end of the support part and the connecting plate, which abuts against the connecting plate.
[0010] As a preferred embodiment of the support mechanism of this utility model, the support part is provided with an adsorption magnetic block on the side away from the abutment protrusion, and the connecting plate is provided with an adsorption magnetic groove that adsorbs the adsorption magnetic block.
[0011] The beneficial effects of the support mechanism of this utility model are as follows: the support part is connected to the cone gate through the installation part, providing a point of leverage for maintenance personnel at the bottom of the cone gate. When maintenance personnel are going up or down the tailpipe, they do not need the assistance of auxiliary personnel at the cone gate. They can go up or down the cone gate by themselves with the help of the support part, thereby reducing reliance on manpower and improving the convenience of the maintenance process.
[0012] Another objective of this invention is to provide an auxiliary device for the upper and lower tailwater pipes, which aims to solve the problem that the working ropes used by maintenance personnel when working on the upper and lower tailwater pipes are prone to friction with the cone gate, thus reducing its service life.
[0013] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: an auxiliary device for upper and lower tailwater pipes, which includes a support mechanism; and an auxiliary component, including a mounting plate disposed above the mounting part, and the mounting plate is provided with mounting bolts for fixing to the cone pipe gate, and a limiting member for limiting the working rope is provided on one side of the mounting plate, and a gripper is provided on the other side.
[0014] As a preferred embodiment of the auxiliary device for the upper and lower tailwater pipes of this utility model, the limiting member includes a support beam fixedly connected to the mounting plate and an auxiliary hole opened on the mounting plate for the working rope to slide. The support beam is provided with a limiting groove corresponding to the auxiliary hole.
[0015] As a preferred embodiment of the auxiliary device for the upper and lower tailwater pipes of this utility model, the support beam is provided with limiting protrusions on both sides of the limiting groove, and the support beam is provided with a reinforcing rod fixedly connected to the mounting plate.
[0016] The beneficial effects of the auxiliary device for the upper and lower tailpipes of this utility model are as follows: By setting up the support beam and the limiting groove, the rope used by maintenance personnel during the climbing process is kept away from the cone gate and the cone wall, reducing the wear of the rope, extending the service life of the related devices, and improving the safety of maintenance personnel during the maintenance process. Furthermore, by setting up the limiting protrusion, the depth of the limiting groove is increased, so that the rope will not easily detach from the support beam, further improving the protection of the rope.

[0023] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0024] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.
[0025] This embodiment provides a support mechanism, such as Figure 1 and Figure 2 As shown, the connecting rod 121 is placed at the bottom of the tapered tube gate. A U-shaped plate 122 is installed at one end of the connecting rod 121. The U-shaped plate 122 is provided with an installation groove 123. The other end of the connecting rod 121 is connected to the support part 11 through the connector 13.
[0026] When installing the upper and lower tailpipes, first place the connecting rod 121 and the U-shaped plate 122 at the bottom of the cone gate, and then connect the mounting part 12 to the cone gate using fixing bolts and the mounting groove 123 on the U-shaped plate 122. Figure 2As shown, the end of the connecting rod 121 away from the U-shaped plate 122 is connected to the support part 11 through the connector 13. Therefore, the support part 11 is also fixed to the cone gate under the action of the mounting part 12. The support part 11 provides a point of leverage for maintenance personnel at the bottom of the cone gate. When lowering the tailpipe, maintenance personnel can first straddle or stand on the support part 11 to adjust the self-climbing device they are equipped with. Because the original cone gate is relatively narrow, it is not convenient for maintenance personnel to operate alone. After the maintenance is completed, the maintenance personnel can first stand on the support part 11 and then use the support part 11 as a point of leverage to exit through the cone gate. Compared with the traditional method, maintenance personnel do not need the assistance of auxiliary personnel at the cone gate. They can leave the cone gate by themselves by cooperating with the support part 11, thereby reducing the dependence on manpower and improving the convenience of the maintenance process.
[0027] Because the bottom of the cone gate frame slopes towards the tailpipe, after the mounting part 12 is connected to the cone gate, the end of the connecting rod 121 connected to the support part 11 is often suspended in mid-air. Therefore, when maintenance personnel stand on the support part 11, the connection between the mounting part 12 and the cone gate will bear a significant pulling force, which is detrimental to increasing the stability of the support mechanism. Therefore, in this embodiment, a through hole 14 and an abutment rod 15 are provided on the end of the connecting rod 121 away from the U-shaped plate 122, and the abutment rod 15 is provided with an abutment thread that connects to the through hole 14. Figure 2 As shown, in actual use, maintenance personnel can rotate the contact rod 15 downwards in advance to adjust the length of the contact rod 15 away from the through hole 14, so that after the connecting rod 121 is installed, one end of the contact rod 15 can contact the cone tube door, providing a new force point for the connecting rod 121, preventing the installation part 12 from falling off the cone tube door during use, and improving the stability of the support mechanism.
[0028] like Figure 3 As shown, connecting plate 131 is rotatably connected to support 11, and connecting plate 132 is connected to connecting rod 121. Connecting plate 131 and connecting plate 132 are respectively provided with corresponding adjustment holes 133 and 134. Therefore, maintenance personnel can control connecting plate 131 to slide on connecting plate 132 according to their own height and other conditions. Then, they can rotate the adjusting bolt 135 set in adjustment hole 133 to move one end into adjustment hole 134, thereby fixing connecting plate 131 and connecting plate 132 and achieving the effect of adjusting the relative position of support 11. This setting allows maintenance personnel of different heights to use the device in a more comfortable state, thereby expanding the applicability of the equipment.
[0029] In this embodiment, the support 11 has both vertical and horizontal states relative to the connecting plate 131. When maintenance personnel need to use the support 11 as a point of leverage, they can rotate it to make the abutment protrusion 111 on the support 11 contact the connecting plate 131, thus achieving the vertical state of the support 11. Figure 2 As shown, the abutment protrusion 111 is located below the support part 11 and near the rotating end of the support part 11. Therefore, when the support part 11 is subjected to a downward pulling force, the abutment protrusion 111 will abut against the connecting plate 131, preventing the support part 11 from rotating further and providing a point of leverage for maintenance personnel. When maintenance personnel leave the support part 11, the support part 11 can be controlled to rotate upward and parallel to the connecting plate 131. This avoids friction between the rope of the self-climbing device and the support part 11, thereby improving the service life of the relevant ropes. Meanwhile, as... Figure 2 As shown, the support part 11 and the connecting plate 131 are provided with mutually attractive magnetic blocks 16 and magnetic grooves 17. When the support part 11 is in a horizontal state, the magnetic blocks 16 and magnetic grooves 17 will provide an attractive force to the support part 11, preventing the support part 11 from easily detaching from the connecting plate 131 under the action of external force, and further reducing the contact between the support part 11 and the rope.
[0030] This embodiment provides auxiliary devices for the upper and lower tailwater pipes, such as... Figure 4 and Figure 5 As shown, the mounting plate 21 is equipped with mounting bolts 22 and a gripper 23. Both of these features facilitate the installation and removal of auxiliary components 2 on the tapered gate by maintenance personnel. Additionally, a support beam 241 is located on the side of the mounting plate 21 opposite to the gripper 23, and a limit groove 243 is provided on the support beam 241. Furthermore, as shown... Figure 4 As shown, the mounting plate 21 is provided with auxiliary holes 242 corresponding to the limiting slide groove 243.
[0031] During use, maintenance personnel can first pass the relevant ropes during the climbing process through the auxiliary hole 242, and then place them on the limiting slide 243. The limiting slide 243 guides the relevant ropes, and the support beam 241 keeps the relevant ropes in the limiting slide 243 away from the cone tube gate and cone tube wall, reducing the wear of the ropes, extending the service life of the relevant devices, and improving the safety of maintenance personnel during the maintenance process.
[0032] like Figure 4As shown, limiting protrusions 244 are provided on both sides of the limiting groove 243. During the climbing process, the ropes may sway due to the movement of the personnel. If the swaying amplitude is large, the ropes may easily slip out of the limiting groove 243 or even detach from the support beam 241. This can easily cause friction between the rope and the spinal canal wall, resulting in damage. Therefore, in this embodiment, limiting protrusions 244 are provided on both sides of the limiting groove 243, effectively increasing the depth of the limiting groove 243. This prevents the rope from easily detaching from the support beam 241, further improving the protection of the rope. Furthermore, as... Figure 5 As shown, a reinforcing rod 245 is provided at the lower part of the support beam 241. The reinforcing rod 245, the mounting plate 21 and the support beam 241 form a triangular area. Because triangles have stability, the setting of the reinforcing rod 245 improves the stability of the connection between the support beam 241 and the mounting plate 21.
[0033] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
