Description

Technical Field

[0001] This application relates to the field of water conservancy engineering protection construction technology, and in particular to a water conservancy engineering carbonization prevention construction device. Background Technology

[0002] In the construction of water conservancy and hydropower projects, hydraulic concrete is the most important aspect of hydraulic structures, especially for permanent hydraulic structures, where its safe operation is crucial. Concrete carbonation is a major factor affecting the durability of hydraulic concrete structures. In severe cases, it can lead to steel reinforcement corrosion, concrete cracking and spalling, damage to the protective layer, and ultimately structural failure, significantly impacting the stability and safety of hydraulic structures. Therefore, taking effective measures to treat the carbonation layer of hydraulic concrete and prevent carbonation is of great significance for improving the durability of concrete structures and protecting the entire hydraulic structure.

[0003] Traditional methods for preventing carbonation mainly involve application of acrylic emulsion and epoxy coatings. However, for the vertical surfaces of concrete structures, cleaning, roughening, and coating operations require scaffolding platforms, resulting in complex processes, long construction periods, significant investment in safety and environmental protection measures, and high raw material costs. Furthermore, water conservancy projects are constrained by flood season and agricultural irrigation, leading to shorter construction periods. Therefore, it is necessary to explore a high-quality, efficient, safe, and environmentally friendly carbonation prevention technology. Summary of the Invention

[0004] In order to meet the requirements of water conservancy project construction operations, this application provides a water conservancy project carbonization prevention construction device.

[0005] The technical solution of the anti-carbonation construction device for water conservancy projects provided in this application is as follows:

[0006] A carbonization prevention construction device for water conservancy projects includes a vehicle body with wheels at the bottom and a support frame on the vehicle body. A construction lifting platform is vertically slidably connected to one end of the support frame. Locking holes are provided circumferentially on the outer walls of the wheels. A locking rod that mates with the locking holes is vertically slidably connected to the vehicle body. A lifting wheel for controlling the lifting of the lifting platform is provided on the support frame. The lifting wheel and the lifting platform are connected by a lifting rope. A control cylinder for controlling the vertical sliding of the locking rod is vertically rotatably connected to the vehicle body. The control cylinder is connected to the locking rod by a thread and to the lifting wheel by a bevel gear pair.

[0007] By adopting the above technical solution, the vehicle travels to the construction location, and construction personnel enter the lifting platform. The lifting wheels lower the platform to the construction location, where personnel can then begin work. During the descent, the lifting wheels drive the control cylinder to rotate via a bevel gear pair. The control cylinder descends via a threaded electric locking rod, which inserts into the locking holes of the traveling wheels to lock them in place, preventing them from rolling and affecting construction safety. The combination of the vehicle and the lifting platform significantly improves work efficiency, and the locking rod enhances safety during operations, thus meeting the construction requirements of water conservancy projects.

[0008] Preferably, the locking rod includes an upper rod and a lower rod, the upper rod is connected to the control cylinder by a thread, the lower rod is engaged with the locking hole, and a buffer spring is provided between the upper rod and the lower rod.

[0009] By adopting the above technical solution, when the lifting wheel drives the control cylinder to rotate via the bevel gear pair, the control cylinder controls the upper rod to descend via a threaded connection until the lower rod is inserted into the locking hole. After the lower rod is inserted into the locking hole, when the lifting platform needs to continue descending, the lifting wheel will continue to rotate, and at this time, the control cylinder will also rotate synchronously. The upper rod continues to descend, compressing the buffer spring. The buffer spring provides movement space for the upper rod, ensuring the movement of the lifting platform.

[0010] Preferably, a connecting piece is rotatably connected to the bottom of the upper rod, and the lower end of the connecting piece is connected to a buffer spring.

[0011] By adopting the above technical solution, when the buffer spring is compressed to its limit, the upper rod cannot continue to move down and rotate synchronously with the control cylinder as the control cylinder continues to rotate, while the buffer spring and the lower rod are unaffected, thus ensuring the locking effect on the traveling wheel.

[0012] Preferably, a counterweight is provided at the end of the support that is away from the lifting platform.

[0013] By adopting the above technical solution, the counterweight maintains the overall balance of the vehicle body, thereby preventing rollover and improving the safety of the vehicle body.

[0014] Preferably, a counterweight rod is horizontally slidably connected to the support, and the counterweight block is installed at the end of the counterweight rod away from the lifting platform.

[0015] By adopting the above technical solution, the position of the counterweight can be adjusted to meet the needs of different working environments. The position can also be adjusted according to the weight on the lifting platform to ensure the stability of the vehicle body.

[0016] Preferably, the lifting platform is equipped with a safety rope, one end of which is movably mounted on the lifting platform and the other end is connected to a counterweight. When the lifting platform is lowered to its lowest position, the safety rope is in a slack state.

[0017] By adopting the above technical solution, during construction operations, the operator attaches the movable end of the safety rope to himself and the other end to the counterweight. When the lifting platform is damaged, the operating safety rope can provide a layer of protection for the operator's safety and prevent the operator from falling.

[0018] Preferably, the bracket has a sliding hole, and the lifting platform has a sliding rod that is slidably connected to the sliding hole. The upper end of the sliding rod is fixed with a fall arrestor block with a diameter larger than the diameter of the sliding hole.

[0019] By adopting the above technical solution, when the lifting platform falls rapidly, the anti-fall block contacts the support, limiting the lifting platform and preventing it from falling further, thereby protecting the operator's safety.

[0020] Preferably, the bracket is equipped with a counterweight cylinder for controlling the extension and retraction of the counterweight rod. The bracket is also equipped with a safety switch located directly above the sliding hole and opposite the anti-fall block. The safety switch is electrically connected to the counterweight cylinder. When the safety switch is triggered, the piston rod of the counterweight cylinder extends fully, that is, the counterweight block is displaced horizontally to the position furthest from the vehicle body.

[0021] By adopting the above technical solution, when the anti-fall block comes into contact with the support, it indicates that the lifting platform is in a dangerous state, and the personnel on the lifting platform are also in a dangerous state. At this time, the counterweight is at the farthest end, which can keep the center of gravity of the vehicle above the ground, and the fact that the counterweight is at the farthest end can keep the safety rope taut, protecting the personnel and preventing them from falling further.

[0022] Preferably, the bracket has a rope hole through which the lifting rope passes. The end of the lifting rope away from the lifting platform has several safety knots, the diameter of which is larger than the diameter of the rope hole.

[0023] By adopting the above technical solution, when the lifting wheel is damaged, causing the lifting rope to unwind rapidly and the lifting platform to descend, the safety knot will be locked at the rope hole when it moves to the rope hole, thereby preventing the lifting platform from falling further and providing an extra layer of safety protection against the fall of the lifting platform.

[0024] Preferably, the lifting platform is equipped with several high-pressure water guns.

[0025] By adopting the above technical solution, high-pressure water guns make it easier for operators to wash concrete layers.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Through the installation of the vehicle body and lifting platform, operators can carry out construction work on the vertical surface of water conservancy projects, meet the corresponding construction requirements, and ensure the safety of operators. Attached Figure Description

[0032] The present application will be further described in detail below with reference to all the accompanying drawings.

[0033] Example

[0034] This application discloses a construction device for preventing carbonation in water conservancy projects, referring to... Figure 1 The system includes a vehicle body 1, with multiple wheels 2 at its bottom. These wheels propel the vehicle body 1 to move on top of the hydraulic engineering structure. The vehicle body 1 also features a lifting platform 4 for construction work, equipped with several high-pressure water guns 44. Operators on the lifting platform 4 perform anti-carbonation work on the vertical surface of the structure.

[0035] Reference Figure 1 The vehicle body 1 is equipped with a support frame 3, and at both ends of the support frame 3 are a lifting platform 4 and a counterweight 33, respectively. A lifting wheel 31 is rotatably connected to the support frame 3, and the lifting wheel 31 is connected to a lifting motor, which drives the lifting wheel 31 to rotate. A lifting rope 32 is connected to the lifting wheel 31, and a rope hole 38 is opened on the support frame 3. The lifting rope 32 passes through the rope hole 38 and is connected to the lifting platform 4 for controlling the lifting of the lifting platform 4.

[0036] Reference Figure 1Several safety knots 321 are provided on the section of the lifting rope 32 near the lifting wheel 31. The diameter of the safety knots 321 is larger than the diameter of the rope hole 38. When the lifting platform 4 suddenly falls uncontrollably, the lifting rope 32 slides rapidly through the rope hole 38 until the safety knots 321 are engaged in the rope hole 38. The lifting rope 32 is then restrained, thus protecting the lifting platform 4 and preventing it from falling further.

[0037] Reference Figure 1 The support frame 3 has a sliding hole 35, and a vertically installed sliding rod 42 is fixed on the lifting platform 4. The sliding rod 42 is slidably connected to the sliding hole 35, and the upper end of the sliding rod 42 protrudes from the sliding hole 35 and is fixedly connected to an anti-fall block 43. The diameter of the anti-fall block 43 is larger than the diameter of the sliding hole 35. When the lifting rope 32 breaks or other accidents cause the lifting platform 4 to fall uncontrollably, the sliding rod 42 descends within the sliding hole 35 until the anti-fall block 43 contacts the support frame 3. The anti-fall block 43 limits the descent distance of the lifting platform 4 to prevent it from falling too far and causing an accident.

[0038] Reference Figure 1 A counterweight cylinder 36 is horizontally mounted on the support 3. A horizontally mounted counterweight rod 34 is fixedly connected to the piston rod of the counterweight cylinder 36. A counterweight block 33 is fixed to the end of the counterweight rod 34 away from the lifting platform 4. The counterweight cylinder 36 drives the counterweight rod 34 to slide horizontally, thereby adjusting the position of the counterweight block 33. This allows the counterweight requirements of the vehicle body 1 to be met under different operating conditions, thus improving the stability of the vehicle body 1.

[0039] Reference Figure 1 A safety rope 41 is attached to the counterweight 33. The end of the safety rope 41 away from the counterweight 33 is located inside the lifting platform 4 and is movably connected to the lifting platform 4 for connecting with the operator. During normal operation, when the lifting platform 4 descends to its lowest position, the safety rope 41 is in a slack state. If the lifting platform 4 falls uncontrollably, the safety rope 41 can pull the operator to prevent the operator from falling with the lifting platform 4.

[0040] Reference Figure 1 The support frame 3 is equipped with a safety switch 37 located directly above the sliding hole 35 and opposite the anti-fall block 43. The safety switch 37 is electrically connected to the counterweight cylinder 36. When the safety switch 37 is triggered, the piston rod of the counterweight cylinder 36 extends fully, meaning the counterweight block 33 moves horizontally to its furthest position from the vehicle body 1. When the anti-fall block 43 contacts the support frame 3, it indicates that the lifting platform 4 has fallen out of control. At this time, the counterweight block 33 is located at the farthest side, ensuring the center of gravity of the vehicle body 1. At the same time, it can also pull the safety rope 41 to pull the operator, preventing the operator from falling with the lifting platform 4, further improving the safety of construction.

[0041] Reference Figure 1 and Figure 2 The vehicle body 1 includes at least four wheels 2, one of which has several locking holes 21 arranged radially along its outer wall. A locking rod 5 is vertically slidably connected to the vehicle body 1, which is directly opposite the locking holes 21. When the locking rod 5 is inserted into the locking hole 21, the vehicle body 1 is locked and cannot move, thus ensuring the stability of the vehicle body 1 during construction operations and improving the safety of the construction operations.

[0042] Reference Figure 1 and Figure 2 A control cylinder 11 is vertically rotatably connected to the bracket 3. The control cylinder 11 is connected to the lifting wheel 31 via a bevel gear pair. When the lifting wheel 31 rotates, the control cylinder 11 rotates synchronously. The locking rod 5 includes an upper rod 51 and a lower rod 52. A connecting piece 54 is rotatably connected to the bottom of the upper rod 51. A buffer spring 53 is connected to the lower end of the connecting piece 54. The lower end of the buffer spring 53 is connected to the upper end of the lower rod 52. The inner wall of the control cylinder 11 is provided with internal threads, and the outer wall of the upper end of the upper rod 51 is provided with external threads. The control cylinder 11 is threadedly connected to the upper rod 51.

[0043] Reference Figure 1 and Figure 2 During construction, the lifting wheel 31 rotates, and the lifting platform 4 descends. At this time, the control cylinder 11 rotates synchronously, the upper rod 51 descends, and the lower rod 52 follows, until the lower rod 52 inserts into the locking hole 21 and locks the traveling wheel 2. Then, the lifting wheel 31 continues to descend, the lifting platform 4 continues to descend, the control cylinder 11 rotates, the upper rod 51 descends, while the lower rod 52 remains stationary. The upper rod 51 compresses the buffer spring 53, providing clearance for its movement. When the buffer spring 53 is compressed to its limit, when the control cylinder 11 continues to rotate, the upper rod 51 cannot continue to descend and thus cannot rotate synchronously with the control cylinder 11, while the buffer spring 53 and the lower rod 52 are unaffected, thereby ensuring the locking effect on the traveling wheel 2.

[0044] The implementation principle of the anti-carbonation construction device for water conservancy projects according to this application embodiment is as follows: During construction, the vehicle body 1 moves to the corresponding position under the drive of the traveling wheels 2, and the operator enters the lifting platform 4. The lifting wheels 31 rotate, and the lifting platform 4 descends. At the same time, the lower rod 52 descends and inserts into the locking hole 21 to fix the traveling wheels 2, thereby locking the vehicle body 1. The counterweight cylinder 36 is activated, and the counterweight block 33 gradually extends out of the vehicle body 1 to balance the vehicle body 1. The operator performs relevant construction operations through the high-pressure water gun 44.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
