Description

Technical Field

[0001] This invention belongs to the field of hydropower station construction technology, specifically relating to a movable and reusable template suitable for various cable trenches in pumped storage power stations. Background Technology

[0002] In existing technologies, the formwork used for cable trench pouring is mostly modular, consisting of multiple steel plates and several steel pipes. Assembly, demolding, dismantling, cleaning, and turnover are all cumbersome. After use, the formwork needs to have its surface cleaned and a fresh release agent applied to ensure a smooth pouring surface. Cleaning and applying the release agent requires manual processing of several formworks individually, rather than simultaneously, thus consuming a significant amount of time. Furthermore, turnover of existing formwork requires many workers to transport all components of the mold to the next pouring location, resulting in high labor costs and inefficiency. Considering the above, the assembly, demolding, cleaning, and turnover processes of the mold are the main factors affecting construction efficiency. Therefore, optimization of these steps is necessary to improve construction efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a movable and reusable template suitable for various cable trenches in pumped storage power stations in order to solve the above problems, as detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a movable and reusable template suitable for various cable trenches in pumped storage power stations, including a main template, with vertical templates on both sides of the main template and baffles installed at both ends of the main template. The main template, together with the two vertical templates, the two baffles and the ground, forms a U-shaped pouring cavity for pouring concrete. The main template is equipped with a release agent spraying assembly, which is used to spray release agent onto the entire surface of the casting cavity formed by the main template, the two vertical templates and the two baffles. The two vertical templates are equipped with cleaning components for cleaning residual concrete on all surfaces of the pouring cavity; The cleaning assembly includes a rubber scraper that can move along the length of the casting cavity; The spraying assembly includes a nozzle for spraying a release agent, the nozzle being mounted on a cleaning assembly and capable of moving along the casting cavity following a rubber scraper. The main template has casters at each of its four corners, and a lifting assembly is provided on the main template to adjust the height of the casters.

[0005] Using the above-mentioned movable and reusable template suitable for various cable trenches of pumped storage power stations, the device is placed in the excavated trench. The casters are moved upward by the lifting component to detach from the ground. At that time, the main template and the two vertical templates will contact the ground, thus forming a pouring cavity. Concrete is poured into the pouring cavity through the opening, and then vibrated and waited for the concrete to solidify. After the concrete has solidified, the casters are moved downward by the lifting assembly, causing them to push against the ground, thereby moving the main formwork, the two vertical formworks, and the two baffles upward to achieve demolding. Then, after removing the two baffles, the device can be pushed along the groove. The cleaning component can clean away the residual concrete on the surface of the main formwork and the two vertical formworks. At the same time, the release agent spraying component can spray the cleaned area with release agent, making it easier for the device to be used for the next pour.

[0006] Preferably, the main template has an opening on its upper side for pouring concrete into the casting cavity.

[0007] Preferably, the lifting assembly includes four screws, which are vertically rotatably mounted on the main template and distributed at the four corners of the main template. A connecting frame is provided above the main template, and the connecting frame is threadedly connected to the four screws. A sprocket is fixedly mounted on each screw, and the four sprockets are connected by chain drive. A turntable is provided at the upper end of each screw, and four support rods are vertically mounted on the connecting frame. Universal wheels are provided at the lower ends of the support rods.

[0008] Preferably, the support rod is slidably connected to the upper side plate of the main template, and handles are provided on both sides of the main template.

[0009] Preferably, the two baffles are bolted to both sides of the vertical template, and the two baffles are in contact with both sides of the main template.

[0010] Preferably, the cleaning assembly includes a guide plate and a mounting frame. Fixed arms are fixedly installed on both vertical templates, and a rotating shaft is rotatably installed between the two fixed arms. A guide plate is fixed on the rotating shaft. The mounting frame is U-shaped and has two horizontal sliding grooves. A guide plate is slidably installed between the two sliding grooves. A mounting plate is installed at one end of the mounting frame corresponding to the main template, and a rubber scraper adapted to the pouring cavity is provided on the edge of the mounting plate.

[0011] Preferably, the rotating shaft has two locking holes, which are arranged in an inverted T-shape on the rotating shaft, and each of the fixing arms is provided with a spring pin, which is used to cooperate with the locking holes to fix the rotating shaft.

[0012] Preferably, the release agent spraying assembly includes a material tank for holding the release agent, the material tank being mounted on a main template, the main template being equipped with a pump and a battery for powering the pump, the pump being connected to the material tank for extracting the release agent, and the output end of the pump being connected to a spray nozzle via a hose, the spray nozzle being mounted on a mounting bracket.

[0013] Preferably, the nozzle is U-shaped, and the surface of the nozzle is provided with a number of nozzle holes, which correspond to the casting cavity.

[0014] Preferably, the mounting bracket is provided with a partition, and the partition is located between the nozzle and the rubber scraper.

[0015] The beneficial effects are: 1. The main formwork, together with two vertical formworks, two baffles, and the ground, forms a U-shaped pouring cavity for pouring concrete. When demolding, only the two baffles need to be removed. The casters are moved downward by the lifting assembly, which pushes the casters downward against the ground, thereby moving the main formwork, two vertical formworks, and two baffles upward to achieve demolding. Then, the device can be moved along the trench to the next pouring position, which can significantly reduce the amount of manual work in dismantling and assembling the formwork and transporting it to the next location, thereby improving construction efficiency. 2. The cleaning component removes residual concrete from the main formwork and the two vertical formwork surfaces. At the same time, the release agent spraying component can spray the cleaned areas with release agent, making it easier for the device to be used in the next pour. This saves time on cleaning the formwork and reapplying the release agent, further improving construction efficiency. 3. The two baffles form a pouring cavity and also improve the stability of the two vertical formworks, thus ensuring the overall stability of the formwork. 4. The posture of the mounting bracket can be adjusted by the cooperation of the spring pin with the two locking holes, the rotating shaft and the guide plate. When the mounting bracket affects the movement of the device in the bend of the groove, the mounting bracket can be rotated to a vertical position to ensure that the device can move smoothly along the groove.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] See Figures 1-6 As shown, the present invention provides a movable and reusable template suitable for various cable trenches of pumped storage power stations, including a main template 1, vertical templates 2 on both sides of the main template 1, and baffles 6 installed at both ends of the main template 1. The main template 1, together with the two vertical templates 2, the two baffles 6 and the ground, forms a U-shaped pouring cavity 7 for pouring concrete. The main template 1 is equipped with a release agent spraying assembly 8, which is used to spray release agent onto the entire surface of the casting cavity 7, which is composed of the main template 1, the two vertical templates 2, and the two baffles 6. Cleaning components 9 are installed on the two vertical templates 2 to clean residual concrete on each side of the pouring cavity 7; The cleaning component 9 includes a rubber scraper 15 that can move along the length of the pouring cavity 7; The spraying assembly 8 includes a nozzle 20 for spraying a release agent. The nozzle 20 is mounted on the cleaning assembly 9 and can move along the casting cavity 7 following the rubber scraper 15. The main template 1 has casters 4 distributed at each of its four corners, and a lifting assembly 3 is provided on the main template 1 to adjust the height of the casters 4.

[0021] As an optional implementation, the main template 1 has an opening 5 on its upper side for pouring concrete into the pouring cavity 7. The opening 5 is rectangular, and setting the opening 5 also facilitates vibration operation.

[0022] The lifting assembly 3 includes four screws 25, which are vertically rotatably mounted on the main template 1 and distributed at the four corners of the main template 1. A connecting frame 27 is provided above the main template 1, and the connecting frame 27 is threadedly connected to the four screws 25. A sprocket 30 is fixedly mounted on the screw 25, and the four sprockets 30 are connected by a chain 29. A turntable 26 is provided at the upper end of the screw 25, and four support rods 28 are vertically mounted on the connecting frame 27. A universal wheel 4 is provided at the lower end of the support rods 28. The four sprockets 30 cooperate with the chain 29 to enable the four screws 25 to move in unison; The turntable 26 rotates the screw 25, and the four screws 25 work together to drive the threaded transmission of the connecting frame 27, making it move vertically. The connecting frame 27 drives the caster 4 to rise and fall through the support rod 28.

[0023] The support rod 28 is slidably connected to the upper side plate of the main template 1. This design can improve the stability of the support rod 28. Handles 31 are provided on both sides of the main template 1, which facilitates the movement of the device.

[0024] Two baffles 6 are bolted to both sides of the vertical template 2, and the two baffles 6 are in contact with both sides of the main template 1 respectively.

[0025] The cleaning component 9 includes a guide plate 11 and a mounting frame 12. Fixed arms 10 are fixedly installed on both vertical templates 2. A rotating shaft 16 is rotatably installed between the two fixed arms 10. The guide plate 11 is fixed on the rotating shaft 16. The mounting frame 12 is U-shaped and has two horizontal sliding grooves 13. The guide plate 11 is slidably installed between the two sliding grooves 13. A mounting plate 14 is installed at one end of the mounting frame 12 corresponding to the main template 1. A rubber scraper 15 adapted to the pouring cavity 7 is installed on the edge of the mounting plate 14. By pushing the mounting frame 12, the mounting plate 14 is driven into the pouring cavity 7. The rubber scraper 15 can scrape off all residual concrete in the pouring cavity 7 except for the ground.

[0026] Two locking holes 17 are provided on the rotating shaft 16, and the two locking holes 17 are distributed in an inverted T-shape on the rotating shaft 16. A spring pin 18 is provided on any one of the fixing arms 10. The spring pin 18 is used to cooperate with the locking holes 17 to fix the rotating shaft 16. The function of the guide plate 11 is to support the mounting frame 12, so that the mounting frame 12 can be pushed into the pouring cavity 7 more easily and effortlessly; The addition of cleaning component 9 increases the overall length of the device, making it difficult for the device to move within the trench. If cleaning component 9 interferes with the movement of the device, the guide plate 11 can be rotated to rotate the mounting bracket 12 to a vertical position. Then, the spring pin 18 is inserted into the corresponding locking hole 17 to fix the rotating shaft 16. Subsequently, other personnel can lift the mounting bracket 12 upwards to prevent it from contacting the bottom of the trench under gravity, thus affecting the movement of the device. This operation is mainly for situations where the device cannot pass smoothly through bends in the trench due to its length.

[0027] The mold release agent spraying assembly 8 includes a material tank 23 for holding the mold release agent. The material tank 23 is set on the main template 1. The main template 1 is equipped with a pump 22 and a battery 24 for supplying power to the pump 22. The pump 22 is connected to the material tank 23 and is used to extract the mold release agent. The output end of the pump 22 is connected to the spray pipe 20 through a hose 21. The spray pipe 20 is set on the mounting frame 12. The release agent is delivered to the nozzle 20 by the pump 22, and sprayed into all areas of the casting cavity 7 except the ground through the nozzle 20. The nozzle 20 follows the mounting frame 12 into the casting cavity 7. It is worth noting that the rubber scraper 15 enters the casting cavity 7 first and cleans it, and then the nozzle 20 sprays the release agent onto the inner wall of the casting cavity 7.

[0028] The nozzle 20 is U-shaped, and the surface of the nozzle 20 is provided with several nozzle holes, which correspond to the casting cavity 7.

[0029] The mounting bracket 12 is provided with a partition 19, which is located between the spray nozzle 20 and the rubber scraper 15. The partition 19 can prevent the release agent from being sprayed onto the rubber scraper 15 and affecting the elasticity of the rubber scraper 15.

[0030] Using the above structure, the device is placed in the excavated trench. The universal wheel 4 is moved upward by the lifting component 3 so that the universal wheel 4 is separated from the ground. At that time, the main template 1 and the two vertical templates 2 will contact the ground, thereby forming the pouring cavity 7. Concrete is poured into the pouring cavity 7 through the opening 5, and then vibrated and waited for the concrete to solidify. After the concrete has solidified, the universal wheels 4 are moved downward by the lifting component 3, so that the universal wheels 4 push downward against the ground, thereby moving the main formwork 1, the two vertical formworks 2 and the two baffles 6 upward to achieve demolding. Then, the two baffles 6 are removed, and the device can be pushed along the groove. The cleaning component 9 cleans away the residual concrete on the surface of the main formwork 1 and the two vertical formwork 2. At the same time, the release agent spraying component 8 can spray the cleaned area with release agent, making it easier for the device to be used for the next pour.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
