Description

Technical Field

[0001] The invention relates to the field of prefabricated aqueducts, and in particular to a storage device for molds in prefabricated aqueducts. Background Art

[0002] Aqueducts are overhead water channels that transport channel water across rivers, valleys, depressions and roads. They have been widely used in various water conservancy projects. Among them, the U-shaped aqueduct used in my country's "South-to-North Water Diversion" project is the largest prefabricated aqueduct in the world so far. It has the characteristics of large size and small wall thickness. The self-weight of the trough is 1,200 tons. The quality of concrete pouring must meet the requirements of high strength, high crack resistance, water seepage resistance and smooth internal and external surfaces.

[0003] Traditional large-scale aqueducts are generally cast-in-place or prefabricated using racks. The former needs to be constructed on the basis of the completion of pier casting, so the construction period is long, and all high-altitude operations are relatively dangerous; while the use of racks for prefabrication, because the aqueduct is large in size, the racks are divided into many blocks, the supporting structure is staggered, the construction period is long, the construction efficiency is low, and the quality is unstable. How to prefabricate aqueducts in large quantities has become an important factor restricting the construction of major projects such as the "South-to-North Water Diversion Project". Prefabricated aqueduct molds generally include outer molds and inner molds, in which the lower part of the cross-section of the inner mold is arc-shaped, which is used to form the U-shaped water-passing surface of the aqueduct. Due to the special structure of the inner mold, if the commonly used storage method is used, the arc section of the lower side mold and the corner mold of the inner mold mold is easily damaged and deformed, and the existing storage devices of the inner molds of the prefabricated aqueducts are all fixed, which is not convenient for transferring the inner molds of the prefabricated aqueducts.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Reference Figure 1 and Figure 2 The storage device of the inner mold of the prefabricated aqueduct shown in the figure comprises an inner mold 4, wherein the inner mold 4 comprises two templates 401 and a bracket 402, wherein the two templates 401 are symmetrically fixedly mounted on both sides of the bracket 402, and further comprises a vehicle body 1 and a buffer mechanism 2, such as Figure 3 As shown, the vehicle body 1 includes a vehicle frame 101, a top cover 102 and two vertical plates 103, the top cover 102 is fixedly mounted on the top of the vehicle frame 101, and the two vertical plates 103 are fixedly mounted on the upper ends of the top cover 102. The buffer mechanism 2 includes a plurality of side buffer assemblies 201, a drive assembly 202, two end buffer assemblies 203, a plurality of load-bearing members 204 and a plurality of load-bearing steel cables 205, and the plurality of side buffer assemblies 201 are symmetrically arranged on the tops of the two vertical plates 103, as shown in FIG. Figure 4 and Figure 5 As shown, the side buffer assembly 201 includes a rotating wheel 2012, the inner mold 4 is arranged above the top cover 102, the rotating wheel 2012 contacts one of the templates 401, and the driving assembly 202 includes a driving shaft 2022, and the driving shaft 2022 is rotatably installed inside the frame 101, as shown in FIG. Figure 6As shown, a plurality of winding wheels 2023 are fixedly installed on the driving shaft 2022, and each of the load-bearing cables 205 is wound around two templates 401 and the corresponding rotating wheel 2012, and both ends of each of the load-bearing cables 205 are fixedly connected to the corresponding winding wheels 2023, and a plurality of the load-bearing members 204 are fixedly installed on the upper end of the top cover 102. When the inner mold 4 is placed in the present invention, the load-bearing member 204 can support the inner mold 4, and the rotating wheel 2012 contacts the side of the template 401 to clamp the two sides of the inner mold 4, and the rotating wheel 2012 can buffer the lateral movement of the inner mold 4. During the descent of the inner mold 4, the load-bearing cables 205 are pressed down and the two ends of the load-bearing cables 205 are pulled. It is wound around the winding wheel 2023, driving the winding wheel 2023 to rotate, thereby driving the driving shaft 2022 to rotate. The driving shaft 2022 can drive the two end buffer components 203 to fit the ends of the template 401. The two end buffer components 203 clamp the ends of the inner mold 4, and the end buffer components can buffer the forward and backward movement of the inner mold 4. After the load-bearing steel cable 205 cannot continue to extend, it is in a tensioned state, which provides further support for the inner mold 4. Through the setting of the above-mentioned structure, it is ensured that the inner mold 4 is not easy to collide with other items when stored, thereby increasing the safety of storage and facilitating the transfer of the inner mold 4. When vibration occurs during the transfer process, the impact force can be buffered to ensure that the inner mold 4 can be safely transferred.

[0022] The vehicle body 1 also includes a plurality of upper fixed pulleys 104 and a plurality of lower fixed pulleys 105. The plurality of upper fixed pulleys 104 are symmetrically rotatably mounted on the upper ends of the two vertical plates 103, and the plurality of lower fixed pulleys 104 are symmetrically rotatably mounted on both sides of the lower end of the top cover 102. Each of the load-bearing steel cables 205 is wound around the corresponding upper fixed pulley 104 and lower fixed pulley 105. The upper fixed pulley 104 and the lower fixed pulley 105 are used to change the direction of the load-bearing steel cable 205 to ensure that it can act on the inner mold 4, the rotating wheel 2012 and the winding wheel 2023 at the same time, so as to play the role of linking the side buffer assembly 201 and the end buffer assembly 203 and supporting the inner mold 4.

[0023] Embodiment 2 is different from the above-mentioned embodiment in that the side buffer assembly 201 further includes an upper rotating rod 2011, a guide rod 2013, a lifting block 2014, a support spring 2015 and a lower rotating rod 2016, the upper rotating rod 2011 is rotatably mounted on the top of the vertical plate 103, the rotating wheel 2012 is rotatably mounted on one end of the upper rotating rod 2011, the inner side surface of the vertical plate 103 is provided with a plurality of notches, the guide rod 2013 is fixedly mounted in the notch, the lifting block 2014 is slidably mounted in the notch, and the guide rod 2013 is inserted through the lifting block 2014, the support spring 2015 is arranged below the lifting block 2014 and sleeved on the guide rod 2013, one end of the lower rotating rod 2016 is connected to the lifting block 20 14 is rotatably connected, and the other end of the lower rotating rod 2016 is rotatably connected with one end of the upper rotating rod 2011. Under normal conditions, the lifting block 2014 is at the highest point of the slot under the action of the supporting spring 2015. The lower rotating rod 2016 supports the upper rotating rod 2011 to rotate upward, and the distance between the rotating wheel 2012 and the vertical plate 103 reaches the maximum. When the inner mold 4 is placed, the sides of the two templates 401 contact the rotating wheel 2012 and push the upper rotating rod 2016 to rotate downward. The transmission of the lower rotating rod 2016 drives the lifting block 2014 to move downward and compress the supporting spring 2015. The elastic force of the supporting spring 2015 is transmitted to the rotating wheel 2012, so that it generates a clamping force on the inner mold 4 and a buffering ability for the lateral displacement of the inner mold 4.

[0024] Embodiment 3 differs from the above embodiments in that the driving assembly 202 further includes two bushings 2021 and a motor 2025, and the two bushings 2021 and the motor 2025 are fixedly mounted inside the vehicle frame 101, and the two ends of the driving shaft 2022 are rotatably connected to the two bushings 2021 respectively, and the output end of the motor 2025 is fixedly connected to one end of the driving shaft 2022, so as to facilitate the driving shaft 2022 to rotate through the motor 2025, and drive the end buffer assembly 203 to reset after taking out the inner mold 4.

[0025] like Figure 7As shown, the end buffer assembly 203 includes a slide plate 2031, a connecting block 2032, a shock absorber 2033 and a baffle 2034. The two ends of the top cover 102 are symmetrically provided with openings. The slide plate 2031 is slidably installed in the openings. The connecting block 2032 is fixedly installed at the lower end of the slide plate 2031. The two ends of the drive shaft 2022 are symmetrically provided with threads 2024. The connecting block 2032 cooperates with the corresponding threads 2024. The shock absorber 2033 is fixedly installed on the slide plate. The inner side of the mold 2031, the baffle 2034 is fixedly installed at the telescopic end of the shock absorber 2033, the driving shaft 2022 rotates to drive the connecting block 2032 to move, thereby driving the slide plate 2031 to move, and when the slide plate 2031 approaches the end of the template 401, the baffle 2034 first contacts the template 401, and then compresses the shock absorber 2033, and the elastic force of the shock absorber 2033 acts on the baffle 2034, which plays a clamping role on the inner mold 4 and has a buffering ability for the lateral movement of the inner mold 4. The height of the baffle 2034 is consistent with the height of the lower ends of the two templates 401, and the length of the baffle 2034 is greater than the distance between the lower ends of the two templates 401, so as to ensure that the baffle 2034 can act on the two templates 401 at the same time.

[0026] Embodiment 4 is different from the above embodiments in that it further comprises two positioning mechanisms 3, and the two positioning mechanisms 3 are symmetrically installed at both ends of the top cover 102. Figure 8 As shown, the positioning mechanism 3 includes two mounting plates 301, a flip plate 302 and two positioning balls 309. The two mounting plates 301 are fixedly mounted on the upper end of the top cover 102, and the flip plate 302 is rotatably mounted between the two mounting plates 301. Two positioning grooves 308 are provided on the top of the flip plate 302, and the two positioning balls 309 are fixedly mounted on one end of the bracket 402. The shapes and positions of the two positioning balls 309 correspond to the shapes and positions of the two positioning grooves 308 respectively. Under normal circumstances, due to the need to buffer the impact force generated during the transfer process, the fixation of the inner mold 4 in the present invention belongs to elastic clamping. The flip plate 302 flips downward and does not contact the positioning balls 309. However, when the inner mold 4 is inspected and repaired, the inner mold 4 needs to be completely fixed, and the flip plate 302 is turned up so that the positioning grooves 308 cooperate with the corresponding positioning balls 309 to ensure that when the flip plate 302 is fixed at this time, the positioning balls 309 act on the bracket 402 to fix it, that is, to ensure that the inner mold 4 is completely fixed, which is convenient for the inspection and repair work.

[0027] The positioning mechanism also includes a rotating shaft 303, two sliders 305, a slide bar 306 and a hook spring 307. The rotating shaft 303 is fixedly installed at the bottom of the flip plate 302. The flip plate 302 is connected to the two mounting plates 301 through the rotating shaft 303. Slide grooves are symmetrically arranged on both sides of the flip plate 302. The two sliders 305 are slidably installed in the corresponding slide grooves. The two ends of the slide bar 306 are respectively fixedly connected to the two sliders 305. The two ends of the hook spring 307 are respectively hung on the rotating shaft 303 and the slide bar 306. A limiting groove 304 is provided on the mounting plate 301. The two ends of the slide bar 306 are respectively inserted into the corresponding limiting groove 304. The limiting groove 304 includes an arc segment and two extension segments. The arc segment is centered on the rotating shaft 303. The two extension segments are arranged at the two ends of the arc segment, and the extension direction points to the rotating shaft 303. Figure 8 The end of the slide bar 306 is in one of the extension sections of the limit groove 304. The limit groove 304 limits the left and right directions of the slide bar 306, and the slide bar 306 is not easy to move upward under the pulling force of the hook spring 307. Therefore, the flip plate 302 cannot be flipped, ensuring that the flip plate 302 is fixed, that is, the fixation of the inner mold 4 is guaranteed, which is convenient for the inspection and maintenance of the inner mold 4. When the fixed state of the inner mold 4 needs to be released, the slide bar 306 is manually pulled up to make the end of the slide bar 306 enter the arc section, and the flip plate 302 is flipped at the same time. The positioning groove 308 is separated from the positioning ball 309, and the inner mold 4 is released from the fixed state. The slide bar 306 moves from one end of the arc section to the other end, and enters another extension section under the action of the hook spring 307, and the flip plate 302 is in a non-flippable state again.

[0028] Working principle: When the present invention is working, the inner mold 4 is slowly placed between the two vertical plates 103 from the top of the present invention, and the sides of the two templates 401 contact the rotating wheel 2012 and the load-bearing steel cable 205. The inner mold 4 pushes the upper rotating rod 2016 to rotate downward, and at the same time presses down the middle part of the load-bearing steel cable 205, and the lower rotating rod 2016 drives the lifting block 2014 to move downward, and compresses the supporting spring 2015. The elastic force of the supporting spring 2015 is transmitted to the rotating wheel 2012, so that the rotating wheel 2012 is close to the template 401, and the middle part of the load-bearing steel cable 205 descends and pulls the two ends. Since both ends of the load-bearing steel cable 205 are wound around the winding wheel 2023, the winding wheel 2023 is driven to rotate, thereby driving the driving shaft 2022 to rotate, and the rotation of the driving shaft 2022 can drive the connecting block 2032 to move. Thereby, the slide plate 2031 is driven to move. When the slide plate 2031 approaches the end of the template 401, the baffle 2034 first contacts the template 401 and then compresses the shock absorber 2033. The elastic force of the shock absorber 2033 acts on the baffle 2034, clamping the inner mold 4. The elastic force of the support spring 2015 and the shock absorber 2033, as well as the downward force of the inner mold 4, act on the load-bearing steel cable 205 at the same time. The direction of the elastic force of the support spring 2015 and the shock absorber 2033 is opposite to the direction of the downward force of the inner mold 4, so that the load-bearing steel cable 205 is in a taut state, and part of the downward force of the inner mold 4 is offset, which further supports the inner mold 4. Moreover, since the steel cable is completely in contact with the template 401, the force on the inner mold 4 is evenly distributed, thereby increasing the stability of the support. When the inner mold 4 needs to be inspected, pull the slide rod 306 so that the end of the slide rod 306 enters the arc section, and at the same time flip the flip plate 302. The slide rod 306 moves from one end of the arc section to the other end, and enters another extension section under the action of the hook spring 307. The flip plate 302 is in a non-flippable state again. At the same time, the positioning ball 309 enters the positioning groove 308, and the positioning ball 309 acts on the bracket 402 to fix it, thereby ensuring that the inner mold 4 is completely fixed, which facilitates the inspection work.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
