Abstract
Description
Technical Field
[0001] This utility model relates to the field of culvert production technology, specifically to a mold device for cement culvert production. Background Technology
[0002] When manufacturing larger culverts, the mold is placed outside the rotating mechanism, and then a steel cage is added inside for fixation. The rotating mechanism then drives the mold to rotate, and concrete material is added to the mold in three stages through the material conveying mechanism. Under the action of centrifugal force, the concrete solidifies. However, in actual operation, after each addition of concrete, the inside of the mold needs to be cleaned manually with a handheld spray nozzle. The purpose is mainly to remove impurities, because during the rotation of the mold, the layers that can be bonded have already formed together, and the unbonded ones are nothing more than large stones, so they are washed away with water. Only in this way can each layer be guaranteed to bond together and ensure quality. However, in actual water washing operations, hand washing is often used, and multiple angles need to be washed, which is inefficient and unsafe. Therefore, a mold device for cement culvert production is proposed to address the above problems. Utility Model Content
[0003] The purpose of this invention is to provide a mold device for the production of cement culverts, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a mold device for producing cement culverts, comprising a rotating device, a culvert mold, and a moving mechanism;
[0005] A culvert mold is provided on one side of the rotating device, and a longitudinally arranged moving mechanism is provided on the front side of the culvert mold. A vertical rod is fixedly connected to the top of the moving mechanism, and a mounting frame is fixedly connected to the top of the vertical rod. A second motor is fixedly connected to one side of the mounting frame, and a rotating cylinder is fixedly connected to the end of the main shaft of the second motor.
[0006] A water pipe mechanism is fixedly connected to the side of the mounting bracket, and multiple water spray heads are connected through a rotating cylinder on one side of the water pipe mechanism. A water pump is externally connected to the other end of the water pipe mechanism.
[0007] Furthermore, the rotation angle range of the second motor is 0-60°.
[0008] Furthermore, the length of the rotating cylinder is the same as the length of the culvert mold.
[0009] When fabricating larger culverts, the mold is placed outside the rotating mechanism, and then a reinforcing cage is added inside for fixation. The rotating mechanism then drives the mold to rotate, and concrete material is added to the mold in three stages through a material conveying mechanism. Under the action of centrifugal force, the concrete solidifies. However, in actual operation, after each addition of concrete, the inside of the mold needs to be manually cleaned with a handheld spray nozzle. The purpose is mainly to remove impurities, because during the rotation of the mold, the layers that can be bonded have already formed together, and the unbonded parts are nothing more than large stones, so they are washed away with water. Only in this way can each layer be guaranteed to bond together and ensure quality. However, in actual water washing operations, it is often done by hand, and multiple... Washing from multiple angles is inefficient and unsafe. This new method uses an external power source. After each concrete layer is laid, a moving mechanism is activated, moving a vertical rod that in turn moves a mounting frame. This, in turn, drives a second motor and a rotating cylinder into the culvert mold. Water is then sprayed from external nozzles to wash the concrete inside the mold, removing larger stones and ensuring good concrete adhesion. Multiple nozzles ensure thorough washing of the inner concrete of the mold. Simultaneously, the second motor rotates the cylinder, allowing the nozzles to rotate and wash all parts of the concrete inside the mold, ensuring good adhesion and significantly improving cleaning efficiency.
[0010] Furthermore, the moving mechanism includes a longitudinal frame, a first motor, and a threaded shaft. The first motor is fixedly connected inside the longitudinal frame, and the threaded shaft is fixedly connected to the end of the main shaft of the first motor. The other end of the threaded shaft is rotatably connected to the longitudinal frame. A threaded sleeve is helically connected to the outer side of the longitudinal frame, and a moving block is fixedly connected to the outer side of the threaded sleeve. The top of the moving block is fixedly connected to the vertical rod, and the outer side of the moving block is slidably connected to the longitudinal frame.
[0011] Furthermore, a storage frame is slidably connected inside the vertical frame, and the storage frame is located below the threaded shaft.
[0012] Furthermore, the length of the threaded shaft is 1.3 times the length of the rotating cylinder.
[0013] The first motor drives the threaded shaft to rotate, which in turn drives the threaded sleeve to move. At this time, the vertical rod can be moved by the action of the moving block, so that the rotating cylinder can be inserted into the culvert mold for subsequent cleaning work. The set storage box can collect the fallen impurities and prevent them from accumulating inside the vertical frame and affecting the use of the equipment.
[0014] Furthermore, the water pipe mechanism includes a mounting plate, a water pipe, and a fixing plate. One side of the mounting plate is fixedly connected to the mounting frame. The water pipe is slidably connected inside the mounting plate, and one end of the water pipe passes through the rotating cylinder and communicates with multiple water spray heads. The other end of the water pipe is externally connected to the pump body. The fixing plate is fixedly connected to the outside of the water pipe, and a spring is fixedly connected to the outside of the fixing plate. The other side of the spring is fixedly connected to the mounting plate.
[0015] When the second motor rotates back and forth, its rotating drum rotates back and forth, which drives the water pipe to move. The fixed plate and spring can ensure that the water pipe is taut and prevent it from becoming loose and affecting the use of the equipment.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. In use, after each concrete laying is completed, the moving mechanism is activated to move the vertical rod, which in turn moves the mounting frame, thereby driving the second motor and the rotating cylinder to enter the culvert mold. At this time, external water is sprayed out through the spray nozzles, which can wash the concrete inside the culvert mold to remove larger stones and ensure the quality of concrete bonding. The multiple spray nozzles can ensure that the concrete inside the culvert mold is thoroughly washed. At the same time, the second motor drives the rotating cylinder to rotate, which ensures that the spray nozzles rotate and wash all parts of the concrete inside the culvert mold, ensuring the quality of bonding and effectively improving cleaning efficiency.
[0018] 2. When the second motor rotates back and forth, its rotating drum rotates back and forth, which drives the water pipe to move. The fixed plate and spring can ensure that the water pipe is taut and prevent it from becoming loose and affecting the use of the equipment.
[0019] The first motor drives the threaded shaft to rotate, which in turn drives the threaded sleeve to move. At this time, the vertical rod can be moved by the action of the moving block, so that the rotating cylinder can be inserted into the culvert mold for subsequent cleaning work. The set storage box can collect the fallen impurities and prevent them from accumulating inside the vertical frame and affecting the use of the equipment. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1: Please refer to Figure 1 This utility model provides a technical solution:
[0026] A mold device for producing cement culverts includes a rotating device 1, a culvert mold 2, and a moving mechanism 3;
[0027] A culvert mold 2 is provided on one side of the aforementioned rotating device 1. A longitudinally arranged moving mechanism 3 is provided on the front side of the aforementioned culvert mold 2. A vertical rod 4 is fixedly connected to the top of the aforementioned moving mechanism 3. A mounting frame 5 is fixedly connected to the top of the aforementioned vertical rod 4. A second motor 6 is fixedly connected to one side of the aforementioned mounting frame 5, and a rotating cylinder 7 is fixedly connected to the end of the main shaft of the second motor 6.
[0028] The mounting bracket 5 is fixedly connected to a water pipe mechanism 9 on its side, and one side of the water pipe mechanism 9 passes through the rotating cylinder 7 and is connected to multiple water spray heads 8. The other end of the water pipe mechanism 9 is connected to an external water pump.
[0029] The rotation angle range of the second motor 6 is 0-60°.
[0030] The length of the rotating cylinder 7 is the same as the length of the culvert mold 2.
[0031] When fabricating larger culverts, the mold is placed outside the rotating mechanism, and then a reinforcing cage is added inside for fixation. The rotating mechanism then drives the mold to rotate, and concrete material is added to the mold in three stages through a material conveying mechanism. Under the action of centrifugal force, the concrete solidifies. However, in actual operation, after each addition of concrete, the inside of the mold needs to be manually cleaned with a handheld spray nozzle. The purpose is mainly to remove impurities, because during the rotation of the mold, the layers that can bond together have already formed together; the only things that cannot bond are large stones, so they are washed away with water. Only in this way can each layer be guaranteed to bond together and ensure quality. However, in actual water washing operations, it is often done by hand and multiple angles need to be washed. Its efficiency is low and its safety is poor. When in use, it is powered by an external power source. After each concrete laying is completed, the moving mechanism 3 is activated to move the vertical rod 4, which in turn moves the mounting frame 5, thereby driving the second motor 6 and the rotating cylinder 7 to enter the culvert mold 2. At this time, external water is sprayed out through the water nozzles 8, which can wash the concrete inside the culvert mold 2 to remove larger stones and ensure the quality of concrete bonding. The setting of multiple water nozzles 8 can ensure that the concrete inside the culvert mold 2 is thoroughly washed. At the same time, the second motor 6 drives the rotating cylinder 7 to rotate, which can ensure that the water nozzles 8 rotate, thereby washing all parts of the concrete inside the culvert mold 2, ensuring the quality of bonding, and effectively improving the cleaning efficiency.
[0032] In this embodiment, the rotation angle range of the second motor 6 is 0-60°. By rotating the second motor 6 back and forth, it can be ensured that the water spray head 8 can fully rinse the inside of the mold 2. Since the water spray head 8 is set at an angle, it is convenient to remove impurities such as stones to ensure the bonding quality. The length of the rotating cylinder 7 is the same as the length of the culvert mold 2, which is convenient to fully clean the impurities in the concrete material inside the culvert mold 2.
[0033] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 2 Specifically, the aforementioned moving mechanism 3 includes a longitudinal frame 301, a first motor 302, and a threaded shaft 303. The first motor 302 is fixedly connected inside the longitudinal frame 301. The threaded shaft 303 is fixedly connected to the end of the main shaft of the first motor 302. The other end of the threaded shaft 303 is rotatably connected to the longitudinal frame 301. A threaded sleeve 304 is helically connected to the outside of the longitudinal frame 301. A moving block 305 is fixedly connected to the outside of the threaded sleeve 304. The top of the moving block 305 is fixedly connected to the vertical rod 4. The outside of the moving block 305 is slidably connected to the longitudinal frame 301.
[0034] The interior of the aforementioned vertical frame 301 is also slidably connected to a storage frame 306, and the storage frame 306 is located below the threaded shaft 303.
[0035] The length of the aforementioned threaded shaft 303 is 1.3 times the length of the rotating cylinder 7.
[0036] The first motor 302 drives the threaded shaft 303 to rotate, and the threaded shaft 303 drives the threaded sleeve 304 to move. At this time, under the action of the moving block 305, the vertical rod 4 can be moved, so that the rotating cylinder 7 can be inserted into the culvert mold 2 for subsequent cleaning work. The set storage frame 306 can collect the fallen impurities and avoid them from accumulating inside the longitudinal frame 301 and affecting the use of the equipment.
[0037] In this embodiment, since the length of the threaded rod 303 is longer than the length of the rotating cylinder 7, it is convenient to thoroughly clean the impurities in the concrete material inside the culvert mold 2.
[0038] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 3 Specifically, the aforementioned water pipe mechanism 9 includes a mounting plate 901, a water pipe 902, and a fixing plate 903. One side of the mounting plate 901 is fixedly connected to the mounting bracket 5. The water pipe 902 is slidably connected inside the mounting plate 901, and one end of the water pipe 902 passes through the rotating cylinder 7 and communicates with multiple water spray heads 8. The other end of the water pipe 902 is externally connected to the pump body. The fixing plate 903 is fixedly connected to the outside of the water pipe 902, and a spring 904 is fixedly connected to the outside of the fixing plate 903. The other side of the spring 904 is fixedly connected to the mounting plate 901.
[0039] When the second motor 6 rotates back and forth, its rotating drum 7 rotates back and forth, which drives the water pipe 902 to move. The fixed plate 903 and spring 904 can ensure that the water pipe 902 is taut and prevent it from becoming loose and affecting the use of the equipment. One end of the rotating drum 7 is set with multiple ports, which makes it easy to connect multiple water spray heads 8 so that the water spray heads 8 can spray fully and ensure that the stones are removed.
