[0002] In the process of road and bridge construction, the use of concrete is crucial, and its quality directly affects the strength, durability and safety of roads and bridges. In order to make the concrete reach a better density, eliminate the air bubbles in it, and eliminate phenomena such as honeycombing and pockmarks, it is necessary to vibrate the concrete.

[0003] However, there are many problems with the existing devices for vibrating concrete for roads and bridges. The traditional vibration method is mostly for workers to hold the vibrating rod for operation. Since the concrete laying area is large and the density is high in road and bridge construction, it is difficult for workers to move the vibrating rod in the concrete, and it is difficult to control the insertion depth. The work is difficult and the efficiency is low. At the same time, the intense vibration generated by the vibrating rod will be transmitted back to the workers' hands, causing physical discomfort and increasing the labor intensity.

[0004] In addition, during the vibration process, the fixation of the concrete mold and the adjustment of the vibration height are not flexible and convenient enough. The existing devices are difficult to stably fix concrete molds of different models, and cannot conveniently adjust the vibration height according to the actual use situation, which to a certain extent limits the efficiency and quality of the vibration operation, and affects the construction progress and project quality of roads and bridges. Therefore, there is an urgent need for a device for homogenizing the vibration of concrete for roads and bridges that can improve the vibration efficiency, is convenient to operate, can flexibly fix the mold and adjust the height.

[0029] By providing the first connecting rod and the second connecting rod, the second rotating shafts on the left and right sides can conveniently and stably drive the second connecting seats, the fixing plates and the sliders at the top on the left and right sides to move inward along the track of the slide rail at the top. This enables the fixing plates to conveniently and stably fix the concrete molds, and can also fix concrete molds of different models, saving time and effort in operation and greatly improving the working efficiency of the vibration operation.

[0030] The overall structure of the device is reasonably designed, and each component works in cooperation, enabling the rapid completion of the fixing of the concrete mold and the preparation for vibration, reducing the time and difficulty of manual operation, and thus improving the overall efficiency of the vibration operation.

[0031] (2) Enhance the stability and practicality of the vibration operation

[0032] The setting of the first electric push rod, the gear and the transmission rod enables the first rotating shafts on the left and right sides to stably and conveniently drive the first connecting rods on the left and right sides to rotate in opposite directions respectively, and then enables the second connecting seats to stably and effectively drive the fixing plates and the sliders at the top to move inward along the track of the slide rail at the top, realizing the stable fixing of the concrete mold by the fixing plates, ensuring that the mold does not shake during the vibration process, and thus enabling the vibration operation to be carried out more stably and effectively, improving the practicality of the vibration device.

[0044] Please refer to Figures 1 to 4, the present invention provides a technical solution:

[0045] I. Detailed description of the device structure

[0046] This road and bridge concrete vibrating and homogenizing device mainly consists of a base, support legs, support blocks, fixed rods, moving rods, a top plate, slide rails, sliders, fixing plates, connecting seats, electric push rods, rotating shafts, gears, connecting rods, vibrating motors and other components. The following elaborates on each component and its connection relationship in detail.

[0047] Base and support legs

[0048] The base 1 serves as the basic support structure of the entire device, and support legs 2 are fixedly connected to the four corners of its lower surface. The number of support legs 2 is set to four groups to ensure stable support for the base 1. To further enhance the support stability, a circular anti-slip pad is fixedly connected to the lower surface of the support legs 2, and a well-shaped anti-slip pattern is provided on the lower surface of the circular anti-slip pad. This design increases the friction between the support legs 2 and the ground, effectively preventing the device from sliding or shaking during the vibrating operation.

[0049] Support blocks, fixed rods and vibrating motors

[0050] Support blocks 3, fixed rods 4 and vibrating motors 20 are fixedly connected to the upper surface of the base 1. The vibrating motor 20 uses a motor of model TO / TB, which is the core power component for realizing the concrete vibrating function.

[0051] Top plate and related components

[0052] A moving rod 5 is inserted into the upper surface of the fixed rod 4, and the moving rod 5 can slide up and down within the fixed rod 4 to achieve height adjustment. The upper surface of the moving rod 5 is fixedly connected to a top plate 6, and slide rails 7 are fixedly connected to both the upper surface and the lower surface of the top plate 6. A slider 8 is sleeved on the outer surface of the slide rail 7, and the slider 8 can freely slide on the slide rail 7.

[0053] A fixing plate 9 is fixedly connected to the upper surface of the slider 8 at the top, and a connecting seat 19 is fixedly connected to the lower surface of the slider 8 at the bottom. To enable the fixing plate 9 to more stably fix the mold, triangular blocks are fixedly connected to both the front and rear sides of the outer surface of the fixing plate 9, and the lower surface of the triangular blocks is welded to the upper surface of the slider 8 at the top. This welding method improves the connection stability between the triangular blocks and the fixing plate 9 and the slider 8 at the top, ensuring that there is no looseness when fixing the concrete mold.

[0054] Electric push rod 1 and transmission components

[0055] On both the left and right sides of the upper surface of the top plate 6, there are fixedly connected electric push rods 10 of type CLA. The output end of the electric push rod 10 is fixedly connected with a transmission rod 11. On both the left and right sides of the upper surface of the top plate 6, there are rotatably connected first rotating shafts 12. A gear 13 is sleeved on the outer surface of the first rotating shaft 12. To enable the transmission rod 11 to stably drive the first rotating shaft 12 to rotate, on the inner side surface of the transmission rod 11, there are fixedly connected transmission wheel teeth meshing with the gear 13, and the number of the transmission wheel teeth is twenty-four groups, and the material is cast iron. This design improves the stability of the linkage between the transmission rod 11 and the first rotating shaft 12.

[0056] At the top of the outer surface of the first rotating shaft 12, there is fixedly connected a first connecting rod 14. At the rear side of the upper surface of the first connecting rod 14, there is inserted a connecting shaft 15. A second connecting rod 16 is sleeved on the outer surface of the connecting shaft 15. On the outer side surface of the fixed plate 9, there is fixedly connected a second connecting seat 17. A second rotating shaft 18 is inserted into the inner side surface of the second connecting seat 17. The inner side of the upper surface of the second connecting rod 16 is inserted with the outer surface of the second rotating shaft 18. By arranging the first connecting rod 14 and the second connecting rod 16, the second rotating shafts 18 on the left and right sides can conveniently and stably drive the second connecting seats 17, the fixed plates 9 and the slider 8 at the top on the left and right sides to move inward along the track of the top rail 7, which can not only stably fix the concrete mold, but also adapt to concrete molds of different models.

[0057] Adjusting rod and electric push rod 2

[0058] A fixed shaft 21 is inserted into the inner side surface of the support block 3. An adjusting rod 22 is sleeved on the outer surface of the fixed shaft 21. Transmission shafts 23 are inserted into the top and bottom of the inner side surface of the adjusting rod 22. A third connecting seat 24 is sleeved on the outer surface of the transmission shaft 23 at the bottom. An electric push rod 25 of type CLA is fixedly connected to the inner side surface of the third connecting seat 24. By arranging the electric push rod 25 and the third connecting seat 24, the transmission shafts 23 on the left and right sides can conveniently and effectively move inward or outward, and further can conveniently and stably adjust the included angle formed by the adjusting rods 22 on the front and rear sides, so that the top plate 6 can stably and conveniently drive the moving rod 5 to move up and down along the track of the fixed rod 4.

[0059] To enable the gear 13 to stably drive the first rotating shaft 12 to rotate, a rectangular block is fixedly connected to the bottom of the outer surface of the first rotating shaft 12, and the structure formed by the rectangular block and the first rotating shaft 12 is inserted into the upper surface of the gear 13, which improves the stability of the linkage between the gear 13 and the first rotating shaft 12. To make the fixed rod 4 more stable in limiting the moving rod 5, a trapezoidal cylinder is sleeved on the bottom of the outer surface of the fixed rod 4, and the material of the trapezoidal cylinder is stainless steel, and the inner diameter of the upper surface of the trapezoidal cylinder is equal to the maximum inner diameter of the fixed rod 4, which improves the stability of the connection between the fixed rod 4 and the base 1.

[0060] II. Device usage steps

[0061] Roof height adjustment

[0062] First, start the second electric push rod 25. The output end of the second electric push rod 25 contracts, and the connecting seats three 24 on the left and right sides drive the drive shafts 23 at the bottom on the left and right sides to move inward respectively. Since the adjusting rod 22 is connected to the support block 3 through the fixed shaft 21, and the top and bottom of the inner side of the adjusting rod 22 are inserted into the drive shaft 23, the vertical angle between the adjusting rods 22 on the front and back sides becomes smaller.

[0063] As the angle of the adjusting rod 22 changes, the drive shaft 23 at the top drives the connecting seat one 19 and the slider 8 at the bottom to move inward along the bottom slide rail 7, and then the roof 6 drives the moving rod 5 to move upward. When the distance between the lower surface of the roof 6 and the upper surface of the base 1 is one meter, turn off the second electric push rod 25 to complete the preliminary adjustment of the height of the roof 6.

[0064] Place the mold and pour concrete

[0065] Place the concrete mold on the upper surface of the top slide rail 7 to ensure that the mold is placed stably. Then pour the concrete into the concrete mold, and pay attention to the uniformity during the pouring process to avoid local accumulation or voids.

[0066] Fix the concrete mold

[0067] Start the first electric push rods 10 on the left and right sides simultaneously. The output ends of the first electric push rods 10 drive the transmission rods 11 to move backward. Since the transmission gear teeth on the inner side of the transmission rod 11 are engaged with the gears 13, the gears 13 on the left and right sides drive the rotating shafts one 12 and the connecting rods one 14 on the left and right sides to rotate in opposite directions respectively.

[0068] The connecting rod one 14 drives the connecting shaft 15 and the connecting rod two 16 to move. The inner side of the upper surface of the connecting rod two 16 is inserted into the outer surface of the rotating shaft two 18, so that the rotating shaft two 18 drives the connecting seat two 17 to move inward, and then the fixing plate 9 drives the slider 8 at the top to move inward along the top slide rail 7. When the inner side of the fixing plate 9 is in close contact with the outer side of the concrete mold, turn off the first electric push rod 10 to complete the fixing of the concrete mold.

[0069] Vibrating operation

[0070] Finally, start the vibration motor 20. The vibration motor 20 starts to work, and the generated vibration is transmitted to the concrete mold and the concrete inside through the base 1 to vibrate the concrete. During the vibration process, due to the stable connection and coordinated work among the components of the device, it can ensure uniform vibration of the concrete and improve the density and quality of the concrete.

[0071] III. Summary of device advantages

[0072] Improve vibration efficiency

[0073] By setting the connecting rod 14 and the connecting rod 2 16, different types of concrete molds can be conveniently and stably fixed, which saves time and effort, and greatly improves the work efficiency of the vibration operation. In actual construction, the mold fixing and vibration preparation work can be completed quickly, reducing manual operation time and labor intensity.

[0074] Enhance the stability and practicality of vibration operation

[0075] The coordinated action of the electric push rod 10, the gear 13 and the transmission rod 11 enables the fixing plate 9 to stably and conveniently fix the concrete mold, ensuring that the mold will not shake during the vibration process, thereby improving the stability and practicality of the vibration operation. At the same time, the design of the transmission gear and the gear 13, the rectangular block and the like further enhances the linkage stability between the components.

[0076] Convenient height adjustment

[0077] The arrangement of the electric push rod 25 and the connecting seat 3 24 enables the device to conveniently adjust the height of the top plate 6 according to the usage. In different construction scenarios, such as the construction of concrete layers of different thicknesses, the height of the top plate can be flexibly adjusted to meet actual needs, greatly improving the practicality and applicability of the device.

[0078] Improve overall stability

[0079] The circular anti-skid pad and well-shaped anti-skid pattern under the support leg 2 increase the friction with the ground, ensure the overall stability of the device during the vibration process, and prevent displacement due to vibration. The trapezoidal cylinder outside the fixed rod 4 improves the connection stability between it and the base 1, ensuring that the moving rod 5 can be stably raised and lowered inside the fixed rod 4. The welding connection between the triangular block on the outside of the fixed plate 9 and the slider 8 also enhances the stability of the fixed plate when fixing the mold, avoiding looseness or shaking during the vibration process, thereby ensuring the quality of the vibration operation.

[0080] 4. Maintenance and care

[0081] Daily inspection

[0082] Before using the device each time, check all parts. Check whether the anti-skid pad of the support leg 2 is worn or damaged. If so, replace it in time to ensure the stability of the support.

If so, clean it in time to prevent affecting the normal operation of the motor. At the same time, check whether there are foreign objects or wear on the surfaces of the slide rail 7 and the slider 8. If necessary, clean and lubricate them to ensure smooth sliding of the slider on the slide rail.

[0084] Lubricate regularly

[0085] For the rotating components in the device, such as the first rotating shaft 12, the second rotating shaft 18, the connecting shaft 15, etc., add lubricating oil regularly to reduce the friction between components and extend their service life. For parts such as the screw rod of the electric push rod, lubrication is also required according to the requirements of the operation manual to ensure its transmission efficiency and stability.

[0086] Electrical system maintenance

[0087] The electrical components in the device are all electrically connected to the external main controller and 220V mains power supply. Regularly check the insulation of the electrical circuit to prevent electric leakage accidents. Check the operating status of the main controller to ensure that it can accurately control the operation of each electrical component. If any damaged electrical component is found, replace it with a component of the same specification in time to ensure the normal operation of the device.
