Description

Technical Field

[0001] This application relates to the field of hydraulic engineering construction equipment technology, specifically to a construction device for spillway dams. Background Technology

[0002] As a crucial facility in water conservancy projects, the construction quality of spillway dams directly affects the safety and durability of the dam body. Currently, spillway dam construction mainly relies on large lifting equipment, formwork systems, and concrete conveying equipment. With the expansion of water conservancy projects and the increase in technical requirements, traditional construction equipment faces challenges in terms of efficiency, precision, and adaptability.

[0003] In the traditional concrete pouring process, pumped concrete is usually used in conjunction with manual vibration. Although this can ensure the density of the concrete, it requires too much manual intervention. Furthermore, manual hand-held vibration can lead to inaccurate positioning and poor quality stability. To solve these problems, a construction device for spillway dams is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a construction device for spillway dams that achieves a certain degree of automated construction, solving the problems of inaccurate positioning and high labor intensity associated with manual hand-held vibrators.

[0005] To achieve the above objectives, this application provides the following technical solution: a construction device for an overflow dam, comprising a support assembly, an auxiliary assembly, and a vibrating assembly. The auxiliary assembly includes a trolley movable above the support assembly. An electric push rod is fixedly connected to the bottom surface of the trolley, and a base plate is fixedly connected to the bottom end of the electric push rod. The vibrating assembly includes a rotating rod rotatably sleeved on the bottom of the base plate. A horizontal telescopic arm is fixedly connected to the bottom end of the rotating rod. A connecting block is fixedly connected to the output end of the horizontal telescopic arm. A buffer pad is fixedly connected to the bottom surface of the connecting block. A vibrator body is installed at the bottom of the buffer pad. A worm gear is fixedly connected to the outer surface of the horizontal telescopic arm. A worm and a third servo motor are installed on the bottom surface of the base plate. The worm meshes with the worm gear. The output shaft end of the third servo motor is fixedly connected to the rotating shaft end of the worm. Discharge pipes are installed on both sides of the base plate, and a solenoid valve is installed on each section of the discharge pipe.

[0006] The above scheme, with its supporting components, auxiliary components, and vibrating components working together, enables flexible adjustment of the vibrator's position, thereby improving the accuracy of vibration, reducing manual intervention, and making it more practical. At the same time, the trolley can store a certain amount of concrete, which, together with the supporting components and vibrating components, also facilitates the pouring of concrete for the spillway construction below.

[0007] Furthermore, the support assembly includes a main steel frame and two slide rails fixedly connected to the upper surface of the main steel frame. Each slide rail has a lead screw rotatably sleeved on its inner wall, and the two sides of the bottom of the trolley are respectively threaded to the outer surfaces of the two lead screws.

[0008] With the above solution, when the two lead screws rotate synchronously, the pulley can move stably above the main steel frame, which facilitates subsequent precise vibration work and reduces the need for manual intervention.

[0009] Furthermore, the main steel frame is provided with a first servo motor and a chain on its exterior. The first servo motor is fixedly connected to the outer surface of the corresponding slide rail, and the output shaft end of the first servo motor is fixedly connected to the rotating shaft end of the corresponding lead screw.

[0010] With the above scheme, when the first servo motor starts, it will drive the corresponding lead screw to rotate.

[0011] Furthermore, a sprocket is fixedly connected to the same end of both lead screws, and the two sprockets are connected by a chain drive.

[0012] With the above method, when one of the two sprockets rotates, the other sprocket can be rotated together with the help of the chain.

[0013] Furthermore, both ends of the main steel frame are fixedly connected with connecting positioning plates.

[0014] The above scheme allows the connecting positioning plates to position both ends of the main steel frame along the overflow dam axis, which is beneficial for subsequent stable pouring and vibration work.

[0015] Furthermore, two second servo motors are fixedly connected to the bottom surface of the trolley, and a stirring assembly is fixedly connected to the output end of each second servo motor. The stirring assembly is located inside the trolley.

[0016] With the above scheme, when the two second servo motors are started, they will drive the two mixing components to rotate. The rotation of the two mixing components can prevent the concrete from settling inside the trolley, thus optimizing the actual pouring effect.

[0017] Furthermore, both sides of the bottom surface of the trolley are connected to high-strength corrugated pipes, and the bottom ends of the two high-strength corrugated pipes are respectively connected to two discharge pipes.

[0018] The high-strength corrugated pipe designed in this way can adapt to changes in the height of the substrate, and thus can cooperate with the discharge pipe to stably transport the concrete inside the trolley to the construction position of the overflow dam below, making it convenient to use.

[0019] Furthermore, guide plates are fixedly connected to both sides of the outer surface of the trolley, and guide rods are fixedly connected to both sides of the upper surface of the base plate. The two guide rods are slidably sleeved on the inner walls of the two guide plates respectively.

[0020] The above scheme, with the guide rod and guide plate working together, ensures the accuracy and stability of the base plate when it moves up and down, which is beneficial to the precise vibration of the vibrator body.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This construction equipment for spillway dams utilizes the linkage between the lead screw, sprocket, and chain in the support assembly to drive the trolley to move precisely along the slide rail. An electric push rod in the auxiliary assembly drives the vertical adjustment of the base plate and vibratory assembly, which, along with guide rods and guide plates, enhances stability. A second servo motor drives the mixing assembly to prevent concrete segregation, and the concrete is continuously transported to the discharge pipe through a high-strength corrugated pipe. The vibratory assembly, driven by a third servo motor, engages with a worm gear and worm wheel, controlling the horizontal telescopic arm to precisely position the vibrator body at multiple angles. Buffer blocks reduce vibration impact, ultimately achieving a certain degree of automated pouring. This completely solves the problems of excessive manual intervention, such as inaccurate positioning, high labor intensity, and large quality fluctuations, significantly improving the concrete density and contour accuracy of the spillway dam.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1 , Figure 3 and Figure 4 This embodiment of a construction device for an overflow dam includes a support assembly 1, an auxiliary assembly 2, and a vibrating assembly 3. The auxiliary assembly 2 includes a trolley 201 that can move above the support assembly 1. The support assembly 1 includes a main steel frame 101 and two slide rails 102 fixedly connected to the upper surface of the main steel frame 101. Each slide rail 102 has a lead screw 103 rotatably sleeved on its inner wall. The two sides of the bottom of the trolley 201 are threaded to the outer surfaces of the two lead screws 103, respectively. When the two lead screws 103 rotate synchronously, the trolley 201 can move stably above the main steel frame 101, thereby facilitating subsequent precise vibration work and reducing the required manual intervention. Please see Figure 2 , Figure 3 and Figure 4 The main steel frame 101 is equipped with a first servo motor 104 and a chain 106 on its exterior. The first servo motor 104 is fixedly connected to the outer surface of the corresponding slide rail 102. The output shaft end of the first servo motor 104 is fixedly connected to the rotating shaft end of the corresponding lead screw 103. When the first servo motor 104 is started, it will drive the corresponding lead screw 103 to rotate. Both ends of the two lead screws 103 are fixedly connected to sprockets 105. The two sprockets 105 are connected by a chain 106. When one of the two sprockets 105 rotates, the other sprocket can be rotated together with the help of the chain 106. Both ends of the main steel frame 101 are fixedly connected to connecting positioning plates 107. The connecting positioning plates 107 can position both ends of the main steel frame 101 along the overflow dam axis, which is beneficial to the subsequent stable pouring and vibration work.

[0026] Please see Figure 2 , Figure 3 and Figure 5An electric push rod 202 is fixedly connected to the bottom surface of the trolley 201. A base plate 203 is fixedly connected to the bottom end of the electric push rod 202. The vibrating assembly 3 includes a rotating rod 301 rotatably sleeved on the bottom of the base plate 203. A horizontal telescopic arm 302 is fixedly connected to the bottom end of the rotating rod 301. A connecting block 306 is fixedly connected to the output end of the horizontal telescopic arm 302. When the horizontal telescopic arm 302 is started, the position of the connecting block 306 can be adjusted. A buffer pad 307 is fixedly connected to the bottom surface of the connecting block 306. A vibrator body 308 is installed at the bottom of the buffer pad 307. By installing the vibrator body 308 under the base plate 203, manual intervention during the vibration process can be reduced and the vibration accuracy can be improved. For improved quality and practicality, a worm gear 303 is fixedly connected to the outer surface of the horizontal telescopic arm 302. A worm 304 and a third servo motor 305 are mounted on the bottom surface of the base plate 203. The worm 304 meshes with the worm gear 303. The output shaft end of the third servo motor 305 is fixedly connected to the rotating shaft end of the worm 304. When the third servo motor 305 starts, it drives the worm 304 to rotate. The rotation of the worm 304 drives the worm gear 303 to drive the horizontal telescopic arm 302 to rotate, which in turn drives the vibrator body 308 to rotate, facilitating stable vibration work at different positions. Discharge pipes 309 are installed on both sides of the base plate 203, and a solenoid valve 310 is installed on each section of the discharge pipe 309.

[0027] Please see Figure 3 , Figure 4 and Figure 5 Two second servo motors 204 are fixedly connected to the bottom surface of the trolley 201. Each second servo motor 204 has a fixedly connected mixing component 205 at its output end. The mixing component 205 is located inside the trolley 201. When the two second servo motors 204 are started, they drive the two mixing components 205 to rotate. The rotation of the two mixing components 205 prevents concrete deposition inside the trolley 201, optimizing the actual pouring effect. High-strength corrugated pipes 206 are connected to both sides of the bottom surface of the trolley 201. The bottom ends of the two high-strength corrugated pipes 206 are respectively connected to two discharge pipes 309. The corrugated pipe 206 can adapt to the height change of the base plate 203, and thus can cooperate with the discharge pipe 309 to stably transport the concrete inside the trolley 201 to the construction position of the overflow dam below, which is convenient to use. Guide plates 208 are fixedly connected to both sides of the outer surface of the trolley 201, and guide rods 207 are fixedly connected to both sides of the upper surface of the base plate 203. The two guide rods 207 are slidably sleeved on the inner walls of the two guide plates 208 respectively. The guide rods 207 and the guide plates 208 cooperate with each other to ensure the accuracy and stability of the base plate 203 when it moves up and down, which is beneficial to the precise vibration work of the vibrator body 308.

[0028] In this embodiment, the construction equipment for the overflow dam, through the linkage of the lead screw 103, sprocket 105, and chain 106 in the support component 1, drives the trolley 201 to move precisely along the slide rail 102. The electric push rod 202 in the auxiliary component 2 drives the base plate 203 and the vibrating component 3 to adjust vertically. The guide rod 207 and guide plate 208 enhance stability. The second servo motor 204 drives the mixing component 205 to prevent concrete segregation and continuously conveys it to the discharge pipe 309 through the high-strength corrugated pipe 206. The vibrating component 3, through the third servo motor 305, drives the worm gear 304 to mesh with the worm wheel 303, controls the horizontal telescopic arm 302 to drive the vibrator body 308 to be precisely positioned at multiple angles. The buffer pad 307 reduces vibration impact, ultimately achieving a certain degree of automated pouring, completely solving the problems of excessive manual intervention, such as inaccurate positioning, high labor intensity, and large quality fluctuations, and significantly improving the concrete density and contour accuracy of the overflow dam.

[0029] The working principle of the above embodiment is as follows: Before construction, the main steel frame 101 of the support component 1 is accurately positioned and fixed along the overflow dam axis by connecting the positioning plate 107. The first servo motor 104 is started to drive the connected lead screw 103 to rotate, and through the transmission of the sprocket 105 and the chain 106, the lead screw 103 on the other side rotates synchronously. The trolley 201 is connected to the two lead screws 103 by threads at its bottom. Under the constraint of the slide rail 102, it moves smoothly and accurately along the length of the main steel frame 101 to the top of the target pouring section. During the concrete conveying process inside the trolley 201, the two second servo motors 204 at its bottom drive the mixing component 205 to work continuously to prevent the concrete from settling and segregating inside the trolley 201. When pouring is required, the concrete is conveyed downward to the discharge pipe 309 through the high-strength corrugated pipe 206 connected on both sides of the bottom surface of the trolley 201, and the discharge position and flow rate of the concrete are precisely controlled by controlling the opening and closing of the solenoid valve 310. Simultaneously, by controlling the extension and retraction of the electric push rod 202 of the auxiliary component 2, the base plate 203 and the entire vibrating assembly 3 mounted on it are driven to adjust their vertical height. During this process, the guide rod 207 fixed to the upper surface of the base plate 203 slides within the guide plate 208 fixed to the outer surface of the trolley 201, ensuring the accuracy and stability of the lifting. After reaching the predetermined height, the third servo motor 305 of the vibrating assembly 3 is activated, driving the worm gear 304 to rotate. The worm gear 304 meshes with the worm wheel 303 fixed to the outer surface of the horizontal telescopic arm 302, thereby driving the horizontal telescopic arm 302 to make precise angle adjustments around the rotating rod 301 in the horizontal plane. The output end of the horizontal telescopic arm 302 is equipped with the vibrator body 308 through the connecting block 306 and the buffer pad 307. Through three-dimensional positioning of horizontal movement, vertical adjustment, and horizontal rotation, the vibrator body 308 is always accurately aligned and inserted into the designated position of the concrete for vibration, and the buffer pad 307 effectively absorbs the vibration impact. While improving the accuracy of pouring and vibration, it effectively reduces manual intervention and the labor intensity of workers, making it more practical.
