Description

Technical Field

[0001] This invention relates to the field of culvert construction technology, specifically a mobile culvert trolley. Background Technology

[0002] Culverts are typically constructed from rock, concrete, or other building materials, and their shapes include circular, elliptical, or square. Their size and shape can also be customized according to specific construction environment requirements. The main function of culverts is to provide underwater transportation and swimming passage. On the ground, culvert trolleys are generally used in the construction of culverts.

[0003] In existing technologies, culvert trolleys support the inner formwork of the culvert after a frame is erected, and then move it into the inner formwork for fixing and subsequent concrete pouring. However, conventional culvert trolleys require a large number of bolt connections when fixing to the inner formwork, which makes the connection difficult, the construction period long, and each connection causes significant wear on the inner wall of the inner formwork. The threaded holes also reduce the overall strength of the inner formwork. On the other hand, when moving the inner formwork into the inner formwork using the culvert trolley, manual positioning is required to ensure that the inner formwork is in the middle of the outer formwork, which also takes up construction time. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a mobile culvert trolley to solve the problems mentioned in the background. This invention can quickly complete the connection and locking between the frame and the inner template, reduce the damage to the inner template caused by each docking, extend the service life, and can be used for the construction of culverts of different sizes and specifications, thus shortening the construction cycle.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mobile culvert trolley, comprising a culvert trolley body, an inner template, and an outer template. The culvert trolley body includes a frame, a guiding mechanism, an extension mechanism, and an auxiliary correction component. The inner template is mounted on the side of the frame and moves to the interior of the outer template via the frame. A vertical plate is mounted on the side of the frame, and an extension mechanism is mounted on the top side of the vertical plate. An auxiliary correction component is mounted at the end of each extension mechanism. A docking groove is mounted on the inner wall of the inner template. A retaining plate is provided at the end of the auxiliary correction component and is embedded into the docking groove via the extension mechanism. A guiding mechanism is mounted at one bottom end of the frame, and horizontal guide wheels are provided on both sides of the guiding mechanism, with each horizontal guide wheel resting against the inner wall of the outer template.

[0006] Furthermore, a base plate is installed at the bottom of the frame, and two movable wheels are installed at both ends of the bottom of the base plate. A crossbar is provided on the inner front side of the base plate, and a positioning slot is provided in the middle of the crossbar.

[0007] Furthermore, a connecting frame is provided on the top of the frame, and four sets of the upright plate, extension mechanism and auxiliary correction component are provided. The two ends of the connecting frame are welded and installed on the top of the two upright plates respectively, and the top of the upright plate is lower than the top of the inner template.

[0008] Furthermore, the guiding mechanism includes a support plate and a horizontal guide wheel. The horizontal guide wheel is installed at the end of the surface of the support plate. A telescopic sleeve is installed at one end of the inner side of the support plate. A spring rod is inserted inside the telescopic sleeve. A central column is installed in the middle of the spring rod.

[0009] Furthermore, a positioning rod is installed at the bottom of the central column, and the front end of the positioning rod is embedded in the interior of the positioning slot. Each central column has a spring rod structure of the same specification installed at both ends, and four sets of horizontal guide wheels are provided.

[0010] Furthermore, the extension mechanism includes a hydraulic rod and a transmission arm. A first rotating base and a second rotating base are mounted on the surface of the upright plate. One end of the hydraulic rod is mounted on the first rotating base, and the second rotating base is movably connected to one end of the transmission arm.

[0011] Furthermore, the surface of the transmission arm is provided with a first connecting shaft, and the end of the hydraulic rod is movably connected to the first connecting shaft, and the hydraulic rod rotates around the first rotating base.

[0012] Furthermore, the auxiliary correction component includes a motor and an adjustment rope. The housing of the motor is fixedly mounted on the side of the transmission arm with screws, and the surface of the transmission arm has grooves.

[0013] Furthermore, the output end of the motor is connected to a drive shaft, the adjustment rope is wound around the surface of the drive shaft, the drive shaft passes through the inside of the groove, and the end of the drive shaft is embedded in the inner wall of the groove through a bearing.

[0014] Furthermore, a second connecting shaft is provided at the end of the transmission arm, and a rotating hole is provided in the middle of the rear end of the card plate. The rotating hole is fitted onto the surface of the second connecting shaft. Hanging rings are installed on both sides of the card plate, and the two ends of the adjusting rope are respectively fixedly connected to the two hanging rings.

[0015] The beneficial effects of this invention are:

[0016] 1. This mobile culvert trolley completes the connection process with the inner template through the side extension mechanism. During docking, locking and subsequent driving can be achieved by plugging in, without the need for a large number of bolts. Therefore, the connection process is simplified and the difficulty of docking is reduced. In addition, the extension mechanism has a certain range of adjustment, which can be used for the construction of culverts of different sizes and specifications.

[0017] 2. Each extension mechanism of the mobile culvert trolley is equipped with an independent auxiliary correction component. Each auxiliary correction component can be embedded into the docking groove in a parallel state through the end plate. This improves the fit during docking, expands the range of transmission force, reduces the wear on the inner wall of the inner template during each connection, and extends the service life.

[0018] 3. The mobile culvert trolley is equipped with a guide mechanism at the rear end of the frame. This guide mechanism can make contact with the inner wall of the outer formwork in advance. Through this docking process, the positioning rod can be moved to the center line position, thereby providing more accurate path guidance when the frame moves. No manual positioning is required, and it can also provide additional positioning effect during the subsequent pouring process, avoiding the impact of concrete from causing the inner formwork to shift, thus improving the accuracy of the final culvert construction.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] Please see Figures 1 to 6 This invention provides a technical solution: a mobile culvert trolley, comprising a culvert trolley body, an inner template 4, and an outer template 3. The culvert trolley body includes a frame 1, a guiding mechanism 2, an extension mechanism 6, and an auxiliary correction component 7. The inner template 4 is installed on the side of the frame 1 and moves to the interior of the outer template 3 via the frame 1. A vertical plate 9 is installed on the side of the frame 1, and an extension mechanism 6 is installed on the top side of the vertical plate 9. An auxiliary correction component 7 is installed at the end of each extension mechanism 6. A docking groove 5 is installed on the inner wall of the inner template 4, and a retaining plate 17 is provided at the end of the auxiliary correction component 7. The retaining plate 17 is embedded into the interior of the docking groove 5 via the extension mechanism 6. A guiding mechanism 2 is installed at one bottom end of the frame 1, and horizontal guide wheels 27 are provided on both sides of the guiding mechanism 2. The horizontal guide wheels 27 all rest against the inner wall of the outer template 3. This mobile culvert trolley is mainly used for supporting and assembling the inner module. When using this culvert trolley for culvert construction, the outer module is first installed and fixed in the preset construction area. Then, by controlling the moving wheels 12 at the bottom of the frame 1, the entire frame 1 is moved to the inside of the inner module. The extension mechanism 6 connects the end plate 17 with the docking groove 5 on the inner module. At this time, the connection and locking process between the inner module and the frame 1 is completed. Then, the guide mechanism 2 is placed inside the outer module. With the help of the guide mechanism 2 to provide a straight path guide, the installed inner module can be moved to the inside of the outer module through the guide mechanism 2. At this time, concrete can be poured into the space between the outer and inner modules to complete the entire culvert construction process.

[0028] In this embodiment, a base plate 8 is installed at the bottom of the frame 1. Two movable wheels 12 are installed at both ends of the bottom of the base plate 8. A crossbar 11 is provided on the inner front side of the base plate 8, and a positioning slot 32 is provided in the middle of the crossbar 11. A connecting frame 10 is provided at the top of the frame 1. Four sets of upright plates 9, extension mechanisms 6, and auxiliary correction components 7 are provided. The two ends of the connecting frame 10 are welded to the top of two upright plates 9 respectively. The top of the upright plates 9 is lower than the top of the inner template 4. Specifically, the frame 1 mainly completes the movement process through the movable wheels 12 at the bottom, and the connecting frame 10 at the top increases the connection performance between each upright plate 9, improving the overall strength of the frame 1. The upright plates 9 on the sides provide support for the extension mechanism 6.

[0029] In this embodiment, the guiding mechanism 2 includes a support plate 26 and horizontal guide wheels 27. The horizontal guide wheels 27 are installed at the end of the surface of the support plate 26. A telescopic sleeve 28 is installed on one end of the inner side of the support plate 26. A spring rod 29 is inserted inside the telescopic sleeve 28. A central column 30 is installed in the middle of the spring rod 29. A positioning rod 31 is installed at the bottom of the central column 30, and the front end of the positioning rod 31 is embedded in the interior of the positioning slot 32. Each central column 30 has spring rod 29 structures of the same specification installed at both ends. Four sets of horizontal guide wheels 27 are provided. The guiding mechanism 2 is installed at the rear end of the frame 1. The guiding mechanism 2 can contact and fit with the inner wall of the outer template 3 in advance. Through this docking process, the positioning rod 31 can be partially moved to the position of the center line, thereby providing more accurate path guidance for the subsequent movement of the frame 1. Manual positioning is not required, and it can also improve the subsequent pouring process. To provide additional positioning effect and prevent the inner formwork 4 from shifting due to the impact of concrete, the accuracy of the culvert after final construction is improved. Specifically, when using the guide mechanism 2, the four sets of horizontal guide wheels 27 at the rear end are directly embedded into the interior of the outer module. With the help of the horizontal guide wheels 27 pressing against the inner wall of the outer module, the inner telescopic sleeve 28 can be moved towards the center under the compression effect. Since the springs on the two spring rods 29 are of the same specification, the compression effect will be evenly applied to each spring rod 29, thereby ensuring that the central column 30 is in the middle position, thus ensuring that the positioning rod 31 is in the middle position of the outer module. When the frame 1 is pulled to move the inner module into the interior of the outer module, the positioning slot 32 is fitted onto the positioning rod 31, and the positioning rod 31 can be used to assist the entire frame 1, ensuring that the vehicle can move the inner module in a straight line along the center line of the outer module into the interior.

[0030] In this embodiment, the extension mechanism 6 includes a hydraulic rod 14 and a transmission arm 16. A first rotating base 13 and a second rotating base 15 are mounted on the surface of the upright plate 9. One end of the hydraulic rod 14 is mounted on the first rotating base 13, and the second rotating base 15 is movably connected to one end of the transmission arm 16. A first connecting shaft 18 is provided on the surface of the transmission arm 16, and the end of the hydraulic rod 14 is partially movably connected to the first connecting shaft 18. The hydraulic rod 14 rotates around the first rotating base 13, and the connection process with the inner template 4 is completed through the side extension mechanism 6. During docking, locking and subsequent driving can be achieved through a plug-in connection. The extension mechanism 6 is flexible and does not require a large number of bolts for connection, thus simplifying the connection process and reducing the difficulty of docking. The extension mechanism 6 has a certain range of adjustment and can be used for the construction of culverts of different sizes and specifications. Specifically, after the hydraulic rod 14 extends outward in the extension mechanism 6, the bottom transmission arm 16 can be pressed down. The transmission arm 16 rotates around the second rotating base 15, and one end of the hydraulic rod 14 rotates around the first rotating base 13. Thus, when the transmission arm 16 moves down, the end plate 17 can be pushed outward until it is embedded in the docking groove 5, thereby completing the docking process with the inner module.

[0031] In this embodiment, the auxiliary correction component 7 includes a motor 22 and an adjusting rope 24. The outer casing of the motor 22 is fixedly mounted on the side of the transmission arm 16 with screws. A groove 19 is formed on the surface of the transmission arm 16. The output end of the motor 22 is connected to a drive shaft 23. The adjusting rope 24 is wound around the surface of the drive shaft 23, and the drive shaft 23 passes through the inside of the groove 19. The end of the drive shaft 23 is embedded in the inner wall of the groove 19 through a bearing. A second connecting shaft 20 is provided at the end of the transmission arm 16. A rotating hole 21 is formed in the middle of the rear end of the clamping plate 17. The rotating hole 21 is fitted onto the surface of the second connecting shaft 20. Hanging rings 25 are installed on both sides of the clamping plate 17, and the two ends of the adjusting rope 24 are respectively fixedly connected to the two hanging rings 25. A unique... The auxiliary correction components 7 are upright, and each auxiliary correction component 7 can be embedded into the docking groove 5 in a parallel state through the end plate 17. Therefore, the fit during docking is improved, the range of transmission force is expanded, the wear on the inner wall of the inner template 4 is reduced with each connection, and the service life is extended. When the plate 17 is pushed into the docking groove 5 by the extension mechanism 6, the motor 22 is started at the same time. The motor 22 drives the drive shaft 23 to rotate, which can pull the adjustment ropes 24 at both ends to wind. Therefore, the two ends of the adjustment ropes 24 will be wound and unwound respectively, which causes the top and bottom of the plate 17 to rotate around the second connecting shaft 20 in the middle by means of the change in the length of the adjustment ropes 24 at both ends. This ensures that the plate 17 always remains in a vertical downward state, so that the above-mentioned process of embedding into the docking groove 5 can be carried out.
