Technical Field

[0001] The invention relates to the technical field of vibration equipment, and in particular to an inner mold vibration mechanism for a concrete component vibration table. Background Art

[0002] In the construction of urban and rural infrastructure, a large number of concrete components are needed, such as inspection wells, water collection wells, etc. At present, most of these concrete components adopt prefabricated assembled structures, that is, through prefabricated molds, the on-site work in the traditional construction method is transferred to the factory, which not only shortens the operation time, but also reduces the construction difficulty of the construction site, while also ensuring the safety of construction and improving the efficiency of construction.

[0003] In the production and processing of precast concrete components, in order to ensure the molding quality of the components, it is necessary to use a vibration table to compact the concrete components during the pouring process. At present, there are many types of vibration tables used in the industry, but the structure of the vibrator used in the vibration table is relatively simple, and there are generally the following defects: (1) The vibrator adopts a vertical vibration mode, and its eccentric shaft needs to overcome the gravity factor and bear a large load, resulting in serious wear of the eccentric vibrator bearing and poor vibration stability; (2) It is not suitable for the production of components of different sizes, and different types of vibrators need to be configured for the production of components of different sizes, resulting in high equipment costs; (3) The force transmission efficiency during vibration is low, and it is easy to generate unnecessary stress in other directions, resulting in the quality of the components cannot be guaranteed; (4) The operation is inconvenient and requires a high level of operating proficiency of construction personnel. Summary of the invention

[0004] In order to solve the above problems, the present invention provides an inner mold vibration mechanism for a concrete component vibration table which adopts a horizontal vibration mode, is applicable to the production of components of different sizes, and is easy to operate.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] An inner mold vibration mechanism for a concrete component vibration table comprises a vibrator body with an eccentric vibrator, the vibrator body is supported by a flexible mounting frame, the eccentric vibrator of the vibrator body is connected to a transmission shaft, the transmission shaft drives the eccentric vibrator to rotate to generate horizontal vibration force, the outer wall of the vibrator body is provided with a vibration transmission mechanism for contacting and connecting with the inner mold, the vibration transmission mechanism has at least one group, each group of vibration transmission mechanisms comprises at least one fixed contact piece and at least one telescopic contact piece, or comprises at least two telescopic contact pieces.

[0007] A further improvement is that the fixed contact members and the telescopic contact members in each group of the vibration transmission mechanism are dispersedly arranged at the same height of the outer wall of the vibrator body.

[0008] A further improvement is that the telescopic contact member is a hydraulic telescopic cylinder arranged radially outward along the outer wall of the vibrator body.

[0009] A further improvement is that the fixed contact piece is a sector ring plate arranged radially outward along the outer wall of the vibrator body.

[0010] A further improvement is that the flexible mounting frame includes a first structural member and a second structural member, the first structural member is fixedly connected to the bottom end of the vibrator body, the second structural member is located below the first structural member, and the second structural member is flexibly connected to the first structural member through a plurality of flexible support members.

[0011] A further improvement is that the first structural member is a plate member, and the second structural member is composed of two plate members and a plurality of rod members vertically arranged between the two plate members.

[0012] A further improvement is that the transmission shaft comprises

[0013] A first coupling, to which a driving wheel for power input is connected;

[0014] A second coupling connected to an eccentric vibrator core shaft of the vibrator body;

[0015] The first coupling and the second coupling are telescopically connected along the vertical direction.

[0018] The beneficial effects of the present invention are:

[0019] (1) The vibrator can be used for forming concrete components of different sizes through a telescopic and adjustable vibration transmission mechanism, and the vibration transmission mechanism adopts a hydraulic connection structure to ensure a tight connection and strong transmission capacity;

[0020] (2) The vibrator generates horizontal vibration force through the vertical eccentric vibrator, which makes the mold vibrate horizontally continuously, thereby driving the concrete in the mold to be evenly distributed. Compared with vertical vibration, horizontal vibration does not need to overcome the gravity of the component itself, which reduces the wear of the eccentric vibrator bearing. At the same time, it consumes less energy, has higher machine stability and longer service life.

DETAILED DESCRIPTION

[0028] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Combination Figure 1 and Figure 2As shown, an inner mold vibration mechanism for a concrete component vibration table includes a vibrator body 1 with an eccentric vibrator 101, the vibrator body 1 is supported by a flexible mounting frame 2, the eccentric vibrator 101 of the vibrator body 1 is connected to a transmission shaft 3, the transmission shaft 3 drives the eccentric vibrator 101 to rotate to generate a horizontal vibration force (that is, the eccentric vibrator 101 itself is vertically arranged and laterally eccentric), and the outer wall of the vibrator body 1 is provided with a vibration transmission mechanism 4 for contacting and connecting with the inner mold, and there is at least one group of vibration transmission mechanisms 4, and each group of vibration transmission mechanisms 4 includes at least one fixed contact member 401 and at least one telescopic contact member 402, or includes at least two telescopic contact members 402.

[0030] In the present invention, the fixed contact members 401 and the telescopic contact members 402 in each group of vibration transmission mechanisms 4 are dispersedly arranged at the same height of the outer wall of the vibrator body 1. Specifically, the telescopic contact member 402 is a hydraulic telescopic cylinder arranged radially outward along the outer wall of the vibrator body 1, and the length extending to the outer circle can be adjusted to adapt to inner molds of different sizes, and the connection is tight and the transmission capacity is strong. The fixed contact member 401 is a fan-shaped plate arranged radially outward along the outer wall of the vibrator body 1, which facilitates the contact between the edge of the outer circle and the inner mold of the molding mold. In addition, the fan-shaped plate and the hydraulic telescopic cylinder are both installed by an arc plate matching the outer wall of the vibrator body 1. Preferably, there are two groups of vibration transmission mechanisms 4, and each group of vibration transmission mechanisms 4 includes two fixed contact members 401 and one telescopic contact member 402, and the three contact members are evenly dispersed on the circumference of the outer wall of the vibrator body 1.

[0031] In the present invention, the flexible mounting frame 2 includes a first structural member 201 and a second structural member 202. The first structural member 201 is fixedly connected to the bottom end of the vibrator body 1, and the second structural member 202 is located below the first structural member 201. The second structural member 202 and the first structural member 201 are flexibly connected through a plurality of flexible support members 203. Among them, the first structural member 201 is a plate, which can be directly the base plate of the vibrator body 1 or an additional plate, which is fixedly connected to the bottom end of the vibrator body 1 by bolts. Since a high connection strength must be ensured here, the first structural member 201 can also be provided with some reinforcing plates, reinforcing rings and other structures; the second structural member 202 can be composed of two plates and a number of rods erected between the two plates, and the plates and the rods are fixed by bolts. The height of the rods can be adjusted as needed to make the vibrator body 1 suitable for molding molds of different heights, and also provide space for other structural settings; the flexible support members 203 are evenly dispersed and can be made of flexible materials, such as rubber, or metal spring structures; when flexible materials such as rubber are used, the flexible support member 203 can be set as a columnar structure, and a reinforcing bolt is inserted in the center position to prevent rubber collapse and dislocation.

[0032] In the present invention, the transmission shaft 3 includes:

[0033] A first coupling 301, to which a driving wheel 302 for power input is connected, and the driving wheel 302 can be arranged at the bottom end or outer ring of the first coupling 301;

[0034] A second coupling 303, the second coupling 303 is connected to the core shaft of the eccentric vibrator 101 of the vibrator body 1;

[0035] The first coupling 301 and the second coupling 303 are telescopically connected in the vertical direction, that is, the distance between the first coupling 301 and the second coupling 303 can be freely expanded or shortened.

[0036] In order to achieve adjustable distance between the first coupling 301 and the second coupling 303 and ensure transmission at the same time, a first sleeve 304 can be connected to the top end of the first coupling 301, and a second sleeve 305 can be connected to the bottom end of the second coupling 303. A movable rod 306 is provided between the first sleeve 304 and the second sleeve 305. Both ends of the movable rod 306 extend into the first sleeve 304 and the second sleeve 305 respectively, and the movable rod 306 is slidably connected to at least one of the first sleeve 304 and the second sleeve 305 through a spline, that is: when one end of the movable rod 306 is slidably connected to the first sleeve 304 through a spline, the other end is fixedly connected to the second sleeve 305, or when one end of the movable rod 306 is slidably connected to the second sleeve 305 through a spline, the other end is fixedly connected to the first sleeve 304, or both ends are slidably connected through a spline. Of course, the range of sliding needs to be limited by a structure at this time.

[0037] In other embodiments, the first sleeve 304 and the second sleeve 305 can be replaced by a solid rod, and the movable rod 306 can be replaced by a pipe fitting, and the three can be spline-connected. Of course, the spline connection has the advantages of uniform force and large load bearing capacity. In some embodiments, a flat key or other structure can also be used as long as the axial movement and radial synchronous transmission can be guaranteed.

[0038] The vibrator realizes flexible installation of the vibrator body 1 by setting the flexible mounting frame 2 and the transmission shaft 3. Therefore, when the vibrator body 1 vibrates horizontally, the unnecessary stress in the vertical direction generated during the rotation of the eccentric vibrator 101 can be eliminated, thereby ensuring the quality of the concrete component. In addition, in a preferred embodiment, the flexible mounting frame 2 and the transmission shaft 3 are both located at the bottom end of the vibrator body 1. Therefore, the plate in the flexible mounting frame 2 needs to be provided with a through hole in the middle to allow the transmission shaft 3 or the corresponding rotating shaft to be inserted. At the same time, a number of bearings can be added at the insertion position to improve the stability of the transmission.

[0039] It should be noted that the transmission shaft 3 can be replaced by a universal coupling to play a role in buffering, reducing vibration and improving the dynamic performance of the shaft system. This implementation also falls within the protection scope of the present application.

[0040] In the present invention, the top of the vibrator body 1 is a conical structure, such as a cone, a pyramid, etc., which can facilitate the connection of the molding die with the vibrator body 1 during the hoisting process.

[0041] Combination Figure 3 As shown, the vibrator needs to be installed using a base 5 before use. The base 5 can be a whole rectangular or circular structure, or in order to reduce weight and material loss, the base 5 can be set to a cross structure, that is, it includes four symmetrical extended edges. At the same time, a driving member 6 is set for transmission connection with the driving wheel 302. The vibrator body 1 is installed at the center position of the top surface of the base 5 through a flexible mounting frame 2, and a track is formed along the length direction of the four extended edges of the base 5. A support 7 is movably set on each track to support the mold and play a guiding, limiting and buffering role.

[0042] Recombination Figure 4 As shown, after the vibrator is installed, when forming a concrete component, it is necessary to first assemble the outer mold 8 and the inner mold 9 of the forming mold, and then use the lifting equipment to lift the assembled mold to the top of the vibrator, and at the same time adjust the position of each support 7 on the track according to the size of the mold, and then slowly lower the mold so that the bottom of the mold is supported on each support 7, and the vibrator body 1 is sleeved in the gap position in the middle of the inner mold 9, and then driven by hydraulic pressure so that the vibration transmission mechanism 4 is in close contact with the inner wall of the inner mold 9. At this time, the vibrator can be started and the concrete can be poured. During the pouring process, the vibrator generates horizontal vibration force, which makes the mold vibrate continuously horizontally, thereby driving the concrete in the mold to be evenly distributed.

[0043] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
