Description

Technical Field

[0001] The utility model relates to the technical field of maintenance of hydropower stations, in particular to an adjustable maintenance system for a flow channel of a dam body flood discharge surface hole. Background Art

[0002] Due to long-term operation, the walls of the dam body flood discharge channel will be eroded and worn to varying degrees, and regular maintenance is required. During maintenance, due to the limitations of construction conditions and the constraints of the construction environment, it is generally necessary to temporarily set up a maintenance platform to carry out maintenance work on the flood discharge channel.

[0003] However, the cost of setting up a temporary maintenance platform is high and the efficiency is low. Therefore, it is considered to use a mobile vehicle carrying the maintenance platform for maintenance. Since the surface hole flow channel has a large slope, steel cables are generally used to pull the vehicle body to prevent the vehicle from slipping.

[0004] Since the slope of the entire flood discharge surface hole flow channel is not constant, especially there are generally several points with large slope changes at high positions. When the vehicle body gradually descends along the flood discharge surface hole flow channel, the steel cable is stretched, and it is highly likely to come into contact and rub against the ground at the points where the slope changes greatly at high positions of the flood discharge surface hole flow channel. Long-term friction will not only easily damage the ground of the flood discharge surface hole flow channel and the steel cable itself, but also cause the steel cable to partially tilt or roll due to friction, scratches, etc., which will then affect the movement of the vehicle body and even cause the vehicle body to tilt sideways, posing a serious safety hazard.

[0031] The adjustable maintenance system for the flood discharge surface orifice flow channel of the dam body provided in the present embodiment is provided with a vehicle body 10, and a maintenance platform 11 is provided on the vehicle body 10, so that the maintenance platform 11 can carry maintenance personnel and move with the vehicle, so as to take into account the whole process of the flood discharge surface orifice flow channel to be inspected; on this basis, a winding roller 20 and a driving motor 30 are provided, and a steel cable 21 is wound around the winding roller 20, and the winding roller 20 is driven to rotate by the driving motor 30 to realize the retraction and release of the steel cable; on this basis, an adjustable anchoring mechanism is provided, which is set to be located at the highest position of the flood discharge surface orifice flow channel to be inspected, and it is provided to include an anchoring beam 40 and a lifting mechanism, and the two ends of the anchoring beam 40 are slidably connected with the two side walls of the flood discharge surface orifice flow channel to be inspected in the vertical direction, and the two side walls of the flood discharge surface orifice flow channel to be inspected are used to anchor the anchoring beam 40, and the lifting mechanism is used to enable it to slide and rise, and the free end of the steel cable 21 is adjusted. The end is connected to the middle part of the anchoring beam 40, and the anchoring beam 40 is used as an anchor point for fixing the horizontal position of the steel cable 21 to anchor the vehicle body 10. When the vehicle body 10 needs to be moved, the winding roller 20 is driven to rotate by the driving motor 30 to retract and release the steel cable 21. The vehicle body 10 moves along the surface hole flow channel to be inspected under the action of the pulling force of the steel cable 21 or its own gravity. During the process, the steel cable 21 is always in a taut state. When the vehicle body 10 moves downward and causes the steel cable 21 to gradually approach the ground of the surface hole flow channel to be inspected, the anchoring beam 40 is driven to rise by the lifting mechanism, so that the steel cable 21 can be kept or kept away from the ground of the surface hole flow channel to be inspected, thereby avoiding contact or even friction between the steel cable 21 and the ground. Through the mutual cooperation of the above-mentioned features, the adjustable maintenance system for the surface hole flow channel of the dam body can solve the problem of contact between the steel cable used to pull the vehicle body and the ground.

[0032] In order to further improve the horizontal anchoring performance of the anchoring beam 40, the anchoring mechanism also includes a pair of groove rails 41; the two groove rails 41 are symmetrically dug on the side walls on both sides of the highest position of the flood discharge surface orifice flow channel to be inspected, and the groove rails 41 extend in the vertical direction; the two ends of the anchoring beam 40 are respectively located in the two groove rails 41 and are slidably connected to the groove rails 41.

[0033] The end of the anchor beam 40 is limited by the groove wall of the groove rail 41, so as to effectively prevent the anchor beam 40 from derailing when it is subjected to the pulling force of the steel cable 21.

[0034] In order to improve the smoothness of the sliding fit between the anchor beam 40 and the groove rail 41, multiple rollers 42 are provided on both sides of the horizontal direction at both ends of the anchor beam 40. The axis of the roller 42 is arranged parallel to the axis of the winding roller 20, and the roller 42 rolls with the groove wall of the groove rail 41 in the width direction.

[0035] In order to further explain the specific structure of the lifting mechanism, the lifting mechanism includes a pair of lifting motors 43, a pair of hoisting rollers 44 and two pairs of lifting ropes 45. The two hoisting rollers 44 are symmetrically arranged at the top ends of the two groove rails 41, and the hoisting rollers 44 are transmission connected to the corresponding lifting motors 43. The lifting motor 43 is fixedly connected to the side wall of the flood discharge surface orifice flow channel to be inspected. The two lifting ropes 45 are symmetrically wound at the two ends of the corresponding hoisting rollers 44, and the lifting ropes 45 are connected to the top of the anchoring beam 40 through lifting ears.

[0036] The hoisting roller 44 is driven to rotate by the lifting motor 43, and two suspension ropes 45 are twisted and pulled at the same time, so that the anchor beam 40 can be stably lifted and lowered.

[0037] In order to prevent the two suspension ropes 45 from being wound around each other, a partition plate 441 is provided in the middle of the hoisting roller 44 to divide the hoisting roller 44 into two symmetrical sections; the two suspension ropes 45 are respectively wound around the two sides of the partition plate 441 .

[0038] In order to avoid frequent adjustment of the anchor beam 40, the above-mentioned adjustable maintenance system of the dam body flood discharge surface hole flow channel also includes a cable support 50, which is arranged on the bottom wall of the flood discharge surface hole flow channel to be inspected and is located at the high-level slope change of the flood discharge surface hole flow channel to be inspected; the steel cable 21 is supported on the top of the cable support 50.

[0039] The cable support 50 is provided to support the steel cable 21, thereby effectively preventing the steel cable 21 from contacting the ground. When the angle between the two sections of the steel cable 21 on both sides of the cable support 50 is too small, the height of the anchor beam 40 can be adjusted.

[0040] In order to improve the smoothness of the sliding fit between the cable support 50 and the steel cable 21 , a cable support roller 51 is rotatably arranged on the top of the cable support 50 . The cable support roller 51 is arranged horizontally, and the length of the cable support roller 51 is much larger than the diameter of the steel cable 21 .

[0041] In order to prevent the cable support 50 from affecting the movement of the vehicle body 10, a receiving groove 52 is dug below the cable support 50 in the flow channel of the flood discharge surface hole to be repaired; a rotating shaft 53 is horizontally provided at the bottom end of the cable support 50, and the cable support 50 is rotatably connected to the groove wall of the receiving groove 52 through the rotating shaft 53.

[0042] With the above arrangement, when the vehicle body 10 is at the highest position and between the cable support 50 and the anchor beam 40, the cable support 50 is rotated into the receiving groove 52, and the pry plate 54 is exposed. When the vehicle body 10 passes over the pry plate 54, the striker plate 12 contacts and pushes the pry plate 54, so that the cable support 50 is gradually rotated out from the rear of the vehicle body 10. When it is rotated to a certain angle, the counterweight 55 can drive the cable support 50 to automatically stand upright. When the vehicle body 10 moves up to the highest position, the striker plate 12 collides with the cable support 50, and the cable support 50 falls into the receiving groove 52, and the pry plate 54 extends out and is located below the vehicle body 10.

[0043] In order to ensure the stability of the erected cable support 50 , a magnet 56 is laid on the side of the bottom of the receiving groove 52 away from the adjustable anchoring mechanism, and the pry plate 54 and / or the counterweight 55 can be adsorbed by the magnet 56 .

[0044] In order to prevent the cable supporter 50 poured into the receiving groove 52 from being damaged, an elastic buffer layer 57 is laid on one side of the bottom of the receiving groove 52 close to the adjustable anchoring mechanism. The elastic buffer layer 57 is used to receive the cable supporter 50 .
