Description

Technical Field

[0001] The invention relates to a concrete prefabricated part production line, in particular to a concrete vibrating system. Background Art

[0002] In existing precast concrete production lines, large formwork tables are loaded onto a vibration table outside the production line through a lifting system. The vibration table then clamps the large formwork table using a hydraulic clamp and vibrates the concrete poured on the large formwork table to improve the density of the concrete.

[0003] The large formwork platform is large in size and weight, and the concrete that needs to be vibrated on the formwork platform is nearly 10m 3 Therefore, vibrating the large formwork and the concrete on it at the same time requires a lot of energy consumption and generates a lot of noise. In addition, during the vibration operation, the large formwork needs to be peeled off from the precast concrete production line, and after the vibration operation is completed, the large formwork needs to be sent back to the production line, which greatly reduces the working efficiency of the precast concrete production line. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a concrete vibrating system which can realize the vibrating operation without separating the formwork from the production line, in view of the low vibration efficiency of the existing concrete prefabricated parts production line.

[0005] In order to solve the above technical problems, the present invention provides a concrete vibration system, including a precast concrete parts production line, a vibration table base, a vibration table with a vibration motor and a mold table, the precast concrete parts production line is provided with a vibration station, the vibration table base is arranged below the vibration station of the precast concrete parts production line, and a plurality of lifting cylinders are installed on the vibration table base, a bracket is installed on the telescopic arm of the lifting cylinder, the vibration table is supported and fixedly arranged on the bracket by a plurality of elastic elements, and clamps for clamping the mold table and the vibration table into a whole are respectively arranged on both sides of the vibration table.

[0006] The present invention provides a vibration station on a concrete prefabricated parts production line, a vibration table base is provided below the vibration station, a liftable vibration table is provided on the vibration table base by means of a lifting cylinder, and clamps are provided on both sides of the vibration table. When vibrating, the mold table only needs to be stopped at the vibration station, the vibration table is lifted by means of the lifting cylinder, the vibration table and the mold table are clamped and fixed into one body by means of the clamp, the vibration motor is started, the vibration table vibrates, and the vibration of the vibration table is transmitted to the mold table, so that the concrete on the mold table can be vibrated.

[0007] The elastic element is preferably a helical spring.

[0008] The vibration motor is installed under the vibration table.

[0009] Formwork support parts are respectively arranged on both sides of the vibration table, and support feet are respectively arranged on both sides of the formwork table. During the vibration operation, the vibration table abuts against the bottom surface of the formwork table, and the support feet fall on the formwork support parts. The clamp clamps the support feet and the formwork support parts into one piece. When the vibration motor is started, the vibration of the vibration table can be transmitted to the bottom surface of the formwork table. The bottom surface of the formwork table is elastically deformed under the action of the vibration motor, thereby vibrating the concrete on the formwork table without vibrating the entire formwork table.

[0010] The clamp includes a clamping arm and a telescopic cylinder, one end of the clamping arm is hinged to the telescopic arm of the telescopic cylinder via its first hinge point, the other end is bent into a hook body, and the middle part of the clamping arm is hinged to the vibration table via its second hinge point, the cylinder body of the telescopic cylinder is hinged to the vibration table, and the extension or retraction direction of the telescopic arm of the telescopic cylinder is opposite to the swinging direction of the hook body: when the telescopic arm of the telescopic cylinder is extended, the hook body is close to the vibration table; when the telescopic arm of the telescopic cylinder is retracted, the hook body is away from the vibration table.

[0011] When the mold platform and the vibration platform are clamped together, the hook body abuts against the mold platform.

[0012] When the hook body clamps the mold platform and the vibration table, the contact point between the hook body and the mold platform is located on the outside of the second hinge point, so that the supporting force exerted by the mold platform on the hook body due to vibration forms a torque that causes the hook body to rotate inward around the second hinge point. Therefore, under the support force of the mold platform, the hook body has a tendency to clamp further, thereby forming a self-locking state, and the mold platform and the vibration table can be clamped into one without the need for the telescopic cylinder to continuously provide a large thrust.

[0013] In order to facilitate the production of large-area prefabricated concrete parts, one or more vibration tables are arranged below the vibration station.

[0014] Based on the same inventive concept, the present invention also provides a concrete vibration system, including a precast concrete parts production line, a vibration table base, a vibration table with a vibration motor and a mold table, the precast concrete parts production line is provided with a vibration station, the vibration table base is arranged below the vibration station of the precast concrete parts production line, and a plurality of lifting cylinders are installed on the vibration table base, a bracket is installed on the telescopic arm of the lifting cylinder, the vibration table is supported and fixedly arranged on the bracket by a plurality of elastic elements, and a plurality of electromagnets for sucking the mold table and the vibration table into a whole are installed on the vibration table.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1) The vibration table of the present invention can realize the concrete vibration work by only vibrating the bottom surface of the mold table, which effectively reduces the energy consumption and noise of the vibration table;

[0017] 2) The vibration table of the present invention is preset below the vibration station of the concrete precast parts production line. When in use, it is only necessary to lift the vibration table and connect it to the mold table without removing the mold table from the production line, thereby improving the working efficiency of the equipment and reducing the difficulty of equipment design and manufacturing.

[0027] The present invention is further described below in conjunction with specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0028] For the convenience of description, the relative position relationship of each component, such as up, down, left, right, etc., is described according to the layout direction of the drawings in the specification, and does not limit the structure of this patent.

[0029] like Figure 1 - Figure 5 As shown, the first embodiment of the concrete vibrating system of the present invention includes a concrete precast production line (not shown in the figure), a vibration table base 1, a vibration table 5 and a mold table 8. A vibration station is set on the concrete precast production line, and a vibration table base 1 is set below the vibration station of the concrete precast production line. Four lifting cylinders 2 are evenly arranged on the vibration table base 1, and a bracket 3 is installed on the telescopic arm of the lifting cylinder 2. A plurality of elastic elements 7 are evenly arranged on the bracket 3. The bracket 3 supports and is fixedly connected to the vibration table 5 through the plurality of elastic elements 7. In this way, the bracket 3 is connected to the vibration table 5 so that the vibration table 5 can be lifted and lowered together with the bracket 3, and a vibration motor 6 is installed below the vibration table 5. Under the action of the vibration motor 6, the vibration table 5 can vibrate freely.

[0030] Multiple groups of first supports 51 and second supports 52 are arranged in pairs on both sides of the bottom of the vibration table 5, and the second supports 52 are arranged on the inner side of the first supports 51, and the clamps 4 are installed between each group of first supports 51 and second supports 52. The clamp 4 includes a clamp arm 41 and a telescopic cylinder 42. A first hinge point 43 is arranged at one end of the clamp arm 41, a second hinge point 44 is arranged in the middle, and the other end is bent into a hook body 45. The clamp arm 41 is hinged to the telescopic arm of the telescopic cylinder 42 through the first hinge point 43, and the middle part of the clamp arm 41 is hinged to the first support 51 through the second hinge point 44. The cylinder body of the telescopic cylinder 42 is hinged to the second support 52, and the extension or retraction direction of the telescopic cylinder 43 is opposite to the swing direction of the hook body 45 of the clamping arm 41: when the telescopic arm of the telescopic cylinder 43 is extended, the hook body 45 is close to the vibration table 5; when the telescopic arm of the telescopic cylinder 43 is retracted, the hook body 45 is away from the vibration table 5.

[0031] Formwork support parts 53 are respectively provided on both sides of the vibration table 5. Support feet 81 are respectively provided on both sides of the formwork table 8. When the formwork table 8 is transported to the vibrating station, the telescopic arm of the lifting cylinder 2 is extended to make the vibration table 5 rise, and the support feet 81 fall on the formwork support part 53. At the same time, the middle part of the vibration table 5 abuts against the bottom surface of the formwork table 8. Then, the telescopic arm of the telescopic cylinder 42 is extended to push the hook body 45 of the clamping arm 41 close to the vibration table 5. Finally, the hook body 45 abuts against the support feet 81 of the formwork table 8, so that the vibration table 5 and the formwork table 8 are clamped and fixed into one.

[0032] When the clamping arm 41 clamps the mold platform 8, the contact point between the hook body 45 and the mold platform 5 is located on the outside of the second hinge point 44, so that the supporting force exerted by the mold platform 8 on the hook body 45 due to vibration forms a torque that causes the hook body 45 to rotate inward around the second hinge point 44. Therefore, under the support force of the mold platform 8, the hook body 45 tends to be further clamped, forming a self-locking state, and there is no need for the telescopic cylinder 42 to continuously provide a large thrust.

[0033] The elastic element 7 is preferably a helical spring.

[0034] like Figure 6 As shown, the structure of the second embodiment of the concrete vibrating system of the present invention is roughly the same as that of the first embodiment, and the only difference is that the second embodiment replaces the clamp 4 in the first embodiment with an electromagnet 9 installed under the vibrating table 5. When the mold table 8 is transported to the vibrating station, the telescopic arm of the lifting cylinder 2 extends to make the vibrating table 5 rise, and the supporting foot 81 falls on the mold table support part 51, and the middle part of the vibrating table 5 hits the bottom surface of the mold table 8, and then the vibrating table 5 uses the suction force of the electromagnet 9 to firmly absorb the mold table 8, so that the vibration energy of the vibrating table 5 is transmitted to the mold table 8, so that the concrete on the mold table 8 vibrates together with the vibrating table 5, and the concrete is vibrated.

[0035] The first and second embodiments described above both show a mold platform 8 with a vibration platform 5, but the present invention is not limited thereto. A plurality of vibration platforms 5 may be arranged under a mold platform 8, and the plurality of vibration platforms 5 vibrate together to achieve the vibration of concrete.

[0036] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Although the present application is disclosed as a preferred embodiment as above, it is not intended to limit the present application. Any technician familiar with the profession, without departing from the scope of the technical solution of the present application, using the technical content disclosed above to make slight changes or modifications are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
