[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. There are many types of vibration tables currently used in the industry, but they generally have 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 vibration tables 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 a vibrating device for concrete component molding 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] A vibration device for concrete component molding comprises a base and a vibrator vertically arranged on the base, wherein the base comprises a plurality of tracks radiating from the vibrator as the axis, the tracks are provided with a support for supporting a concrete component molding mold, the vibrator is provided with a vibration transmission member for connecting with the concrete component molding mold, and the vibrator imparts a horizontal vibration force to the concrete component molding mold through the vibration transmission member.

[0007] A further improvement is that the vibrator is flexibly mounted on the base via a mounting frame.

[0008] A further improvement is that the mounting frame comprises:

[0009] A first structural member fixedly connected to the base;

[0010] A second structural member fixedly connected to the vibrator;

[0011] The second structural member is located above the first structural member, and the second structural member is flexibly connected to the first structural member via a plurality of flexible supporting members.

[0012] A further improvement is that the top of the vibrator is a conical structure.

[0013] A further improvement is that there is at least one group of vibration transmitting members, each group of vibration transmitting members includes at least one fixed contact member and at least one telescopic contact member, and the fixed contact members and telescopic contact members in each group of vibration transmitting members are relatively arranged at the same height of the outer wall of the vibrator.

[0014] A further improvement is that the telescopic contact member is a hydraulic telescopic cylinder arranged radially outward along the outer wall of the vibrator.

[0015] A further improvement is that the vibrator is driven to vibrate by a driving member arranged at the bottom of the base, the driving member includes a transmission shaft connected to the vibrator vibrator, and the transmission shaft includes:

[0016] A first coupling, which is rotatably mounted on the base and is connected to a transmission wheel for connecting with a driving member;

[0017] A second coupling connected to a vibrator core shaft of the vibrator;

[0018] The first coupling and the second coupling are telescopically connected along the vertical direction.

[0019] A further improvement is that the top end of the first coupling is connected to a first sleeve, the bottom end of the second coupling is connected to a second sleeve, a movable rod is provided between the first sleeve and the second sleeve, both ends of the movable rod extend into the first sleeve and the second sleeve respectively, and the movable rod is slidably connected to at least one of the first sleeve and the second sleeve through a spline.

[0021] A further improvement is that the support includes a base plate movably arranged along the track, a plurality of flexible buffer parts arranged on the top surface of the base plate, a mounting plate arranged on the top of the flexible buffer parts, and a mold buffer pad and a guide limit plate arranged on the top surface of the mounting plate.

[0022] The beneficial effects of the present invention are:

[0023] (1) The vibration device can be applied to the molding of concrete components of different sizes through a movably mounted support and a telescopically adjustable vibration transmission member, and the vibration transmission member adopts a hydraulic connection structure to ensure a tight connection and a strong transmission capacity;

[0024] (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.

[0025] (3) The vibrator is flexibly installed, and the transmission shaft is vertically retractable, so that the unnecessary vertical stress generated during the rotation of the eccentric vibrator can be eliminated during operation, thereby ensuring the quality of the concrete component;

[0026] (4) The top of the vibrator is set as a conical structure, which, combined with the limiting and guiding functions of the support, can facilitate the connection between the molding mold and the vibration device during the lifting process, reducing the requirements for operating proficiency.

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.

[0034] In the present invention, the vibrator 2 is flexibly mounted on the base 1 through a mounting frame 4, and the mounting frame 4 includes:

[0035] A first structural member 401 fixedly connected to the base 1, the first structural member 401 may be composed of two plates and a plurality of rods vertically arranged between the two plates, the plates and the rods are fixed by bolts, the height of the rods may be adjusted as needed, so that the vibrator 2 is suitable for molding molds of different heights, and also provides space for other structural arrangements;

[0036] The second structural member 402 is fixedly connected to the vibrator 2. The second structural member 402 is a plate member. The plate member can be directly the base plate of the vibrator 2 or an additional plate member. The plate member is also fixedly connected to the bottom end of the vibrator 2 by bolts. Since a high connection strength must be ensured here, the second structural member 402 can also be provided with some reinforcement plates, reinforcement rings, etc.;

[0037] The second structural member 402 is located above the first structural member 401, and the second structural member 402 is flexibly connected to the first structural member 401 through a plurality of flexible support members 403. The flexible support members 403 are evenly dispersed and can be made of a flexible material, such as rubber, or a metal spring structure. When a flexible material such as rubber is used, the flexible support member 403 can be set as a columnar structure, and a reinforcing bolt is inserted in the center to prevent the rubber from collapsing and dislocating.

[0038] In the present invention, the vibrator 2 is driven to vibrate by a driving member 3 disposed at the bottom of the base 1 , and the driving member 3 includes a transmission shaft 6 connected to the vibrator of the vibrator 2 .

[0039] The driving member 3 may be one or more motors, and a pulley or gear is arranged on the output shaft of the motor to realize the transmission of power; the driving member 3 may be directly fixed on the base 1 through a sheet metal part. For example, the driving member 3 uses two motors, and the two motors are symmetrically fixed on the bases 1 on both sides of the vibrator 2 to improve the strength and stability of the drive.

[0040] Wherein, the transmission shaft 6 comprises:

[0041] The first coupling 601 is rotatably mounted on the base 1, and a transmission wheel 602 for connecting to the driving member 3 is connected to the first coupling 601; specifically, a rotating seat can be provided on the base 1 for mounting the transmission wheel 602, and then the first coupling 601 is fixedly mounted on the top of the transmission wheel 602, so that the first coupling 601 and the transmission wheel 602 rotate coaxially. Of course, the first coupling 601 can also be directly mounted on the base 1 through the rotating seat, and then a transmission wheel is installed on the outside, which can be selected and replaced according to needs;

[0042] A second coupling 603, the second coupling 603 is connected to the vibrator core shaft of the vibrator 2, the vibrator core shaft of the vibrator 2 extends downward and is coaxially connected to the second coupling 603;

[0043] The first coupling 601 and the second coupling 603 are telescopically connected in the vertical direction, that is, the distance between the first coupling 601 and the second coupling 603 can be freely expanded or shortened.

[0044] In order to achieve adjustable distance between the first coupling 601 and the second coupling 603 and ensure transmission at the same time, a first sleeve 604 can be connected to the top end of the first coupling 601, and a second sleeve 605 can be connected to the bottom end of the second coupling 603. A movable rod 606 is provided between the first sleeve 604 and the second sleeve 605. Both ends of the movable rod 606 extend into the first sleeve 604 and the second sleeve 605 respectively, and the movable rod 606 is slidably connected to at least one of the first sleeve 604 and the second sleeve 605 through a spline, that is: when one end of the movable rod 606 is slidably connected to the first sleeve 604 through a spline, the other end is fixedly connected to the second sleeve 605, or when one end of the movable rod 606 is slidably connected to the second sleeve 605 through a spline, the other end is fixedly connected to the first sleeve 604, 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.

[0045] In other embodiments, the first sleeve 604 and the second sleeve 605 can be replaced by a solid rod, and the movable rod 606 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.

[0046] The present invention realizes flexible installation of the vibrator 2 by setting the mounting frame 4 and the transmission shaft 6, so when the vibrator 2 vibrates horizontally, the unnecessary stress in the vertical direction generated during the rotation of the eccentric vibrator can be eliminated, thereby ensuring the quality of the concrete component. In addition, in a preferred embodiment, the mounting frame 4 and the transmission shaft 6 are both located at the bottom end of the vibrator 2, so the plate in the mounting frame 4 needs to be provided with a through hole in the middle to allow the transmission shaft 6 or the corresponding rotating shaft to be inserted, and a number of bearings can be added at the insertion position to improve the stability of the transmission.

[0047] It should be noted that the transmission shaft 6 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.

[0048] In the present invention, the top of the vibrator 2 is a conical structure, such as a cone, a pyramid, etc., which can facilitate the connection between the molding die and the vibrator 2 during the hoisting process.

[0049] In the present invention, there is at least one group of vibration transmission members 5, and each group of vibration transmission members 5 includes at least one fixed contact member 501 and at least one telescopic contact member 502. The fixed contact members 501 and telescopic contact members 502 in each group of vibration transmission members 5 are dispersedly arranged at the same height of the outer wall of the vibrator 2. Among them, the fixed contact member 501 is selected to use a fan-shaped plate structure, which is convenient for the edge of the outer ring to contact the inner mold of the forming mold, and the telescopic contact member 502 is selected to use a hydraulic telescopic cylinder structure, which is radially arranged outward along the outer wall of the vibrator 2, and the length extending to the outer ring can be adjusted to adapt to inner molds of different sizes, and the connection is tight and the transmission capacity is strong; in addition, the fan-shaped plate and the hydraulic telescopic cylinder are both installed through an arc plate that matches the outer wall of the vibrator 2. Preferably, there are two groups of vibration transmission members 5, and each group of vibration transmission members 5 includes two fixed contact members 501 and one telescopic contact member 502, and the three contact members are evenly dispersed on the circumference of the outer wall of the vibrator 2.

[0050] In the present invention, the base 1 can be a whole rectangular or circular structure, or in order to reduce weight and material loss, the base 1 can be set to a cross-shaped structure, that is, it includes four symmetrical extended edges, and the vibrator 2 is installed at the center of the top surface of the base 1 through the mounting frame 4, and a track 7 is formed along the length direction of the four extended edges of the base 1. Of course, the extended edges of the base 1 can be other numbers, such as six, eight, etc., which can be evenly arranged.

[0051] In the present invention, the track 7 can be a flat plate structure, and mounting holes are evenly spaced on the track 7, and the bottom end of the support 8 adopts a sliding card structure. The support 8 can select the mounting hole at any position for fixed installation, and the distance between all supports 8 and the central vibrator 2 is individually adjustable, which is convenient for supporting circular, rectangular or other special-shaped molding molds. Of course, the track 7 can also adopt a slide groove structure, and the support 8 slides freely in the slide groove, and is equipped with corresponding locking parts to fix the position. In addition, the track 7 can also be equipped with an electric structure of a bearing seat, a screw rod and a servo motor, and the support 8 is driven to move by the rotation of the screw rod, and the size can be input through the controller to realize automatic adjustment of the support 8.

[0052] In the present invention, the support 8 includes a bottom plate 801 movably arranged along the track 7, and a plurality of flexible buffers 802 arranged on the top surface of the bottom plate 801, and a mounting plate 803 arranged on the top of the flexible buffer 802, and a mold buffer pad 804 and a guide limit plate 805 arranged on the top surface of the mounting plate 803. Among them, the flexible buffers 802 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 buffer 802 can be set as a columnar structure, and a reinforcing bolt is inserted in the center to prevent the rubber from collapsing and dislocating. There are two mold buffer pads 804, which are used to support the inner and outer molds of the molding mold respectively. The mold buffer pads 804 play a buffering role. They can also be made of flexible materials such as rubber, or metal spring structures. The guide and limit plate 805 is generally selected to be set at the outer side of the mold buffer pad 804, and its top is provided with a plate body that is inclined and expanded outward, which is used to position the outer ear seat at the bottom end of the molding mold and plays a guiding and limiting role.

[0053] Recombination Figure 4 As shown, when using the vibration device of the present invention to form concrete components, first assemble the outer mold 9 and the inner mold 10 of the forming mold, then use the lifting equipment to lift the assembled mold to the top of the vibration device, and adjust the position of each support 8 on the track 7 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 8, and the vibrator 2 is sleeved in the gap position in the middle of the inner mold 10, and then driven by hydraulic pressure so that the vibration transmission member 5 is in close contact with the inner wall of the inner mold 10. At this time, the vibrator 2 can be started and the concrete can be poured. During the pouring process, horizontal vibration force is generated, so that the mold continues to vibrate horizontally, thereby driving the concrete in the mold to be evenly distributed.

[0054] 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.
