Description

Technical Field

[0001] The present application relates to the technical field of concrete vibrating equipment, and in particular to a fiber concrete vibrator for residential garage construction. Background Art

[0002] The underground structure of a building is different from the superstructure and is a concealed project. It is exposed to the complex underground environment for a long time, especially the influence of groundwater, which easily leads to quality problems such as penetration and leakage. The waterproof structure of the underground garage of a high-rise building is the top priority of architectural design and construction. Among them, the cushion layer made of fiber concrete is an important part of the waterproof structure.

[0003] The thickness of the waterproof cushion layer of the underground garage is relatively thin, generally less than 30 cm, and a flat vibrator is a more suitable choice. The flat vibrator consists of a flat plate and a vibration motor. The vibration motor generates more heat than ordinary motors and is in a vibration environment for a long time. Relatively speaking, the service life of the vibration motor is relatively low.

[0004] Secondly, since the initial laying thickness of the cushion layer at different positions before vibration is different, the local position of the slab may be suspended during vibration. On the one hand, the cushion layer below the suspension is subjected to weaker vibration force, resulting in substandard vibration. On the other hand, if the suspended position is located at the connection between the slab and the vibration motor, the force generated by the vibration acts here for a long time, which may cause the slab to deform and affect the vibration quality of the cement. Summary of the invention

[0005] This application proposes a fiber concrete vibrator for residential garage construction. The motor and vibrator generate heat independently and do not overlap each other. The operating temperature of each is relatively low. At the same time, the motor operates in an environment with relatively small vibration, which increases the service life. Secondly, a scraper is provided in front of the flat plate. The scraper reciprocates to flatten the concrete in front, which not only ensures the vibration effect, but also reduces the probability of deformation of the flat plate.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a fiber concrete vibrator for residential garage construction, comprising a flat plate, a connecting frame is provided on the flat plate, the flat plate is connected to a motor through a buffer platform, the motor is connected to the vibrator through a second transmission unit, the second transmission unit is constructed to isolate vibration, the motor is connected to a movable frame through a first transmission unit, a scraper is connected to the bottom of the movable frame, the scraper has at least one inclined section, the movable frame is movably connected to the connecting frame, and the first transmission unit drives the movable frame and the scraper to perform reciprocating linear motion back and forth.

[0007] Furthermore, the second transmission unit includes a driving wheel connected to the motor output shaft and a transmission shaft connected to the vibrator input shaft, the transmission shaft is fixedly connected to a driven wheel, the driving wheel is connected to the driven wheel through a transmission belt, a pressure wheel is provided on one side of the transmission belt, the pressure wheel presses the transmission belt so that the transmission belt always maintains an appropriate amount of tension, and the transmission belt can isolate vibration.

[0008] Furthermore, the driving wheel is fixedly connected to the output shaft of the motor, the motor housing is fixedly connected to a connecting ring, the connecting ring is movably connected to a clamping ring, the clamping wheel is arranged on the clamping ring, a torsion spring is arranged between the clamping ring and the connecting ring, so that the clamping wheel moves toward the transmission belt, and the clamping wheel ensures that the tension of the transmission belt is always moderate, and slipping will not occur and the rotating belt will not break.

[0009] Furthermore, the first transmission unit includes a crank drivingly connected to the motor output shaft, the crank is movably connected to a connecting rod, the connecting rod is movably connected to a moving rod, the connecting frame is fixedly connected to a guide cylinder, the moving rod is movably connected to the guide cylinder, and a connecting head is provided at the end of the moving rod, which is movably connected to the moving frame.

[0010] Furthermore, the movable frame includes a reciprocating frame, which is in the shape of a "Π" and is constructed to be able to stand independently. The reciprocating frame has two front and rear legs. The front leg is located in front of the flat plate and is fixedly connected to the scraper. The rear leg is located behind the flat plate and is fixedly connected to the sliding plate. The reciprocating frame is fixedly connected to a connecting cross plate, which is connected to a connecting head.

[0011] Furthermore, the mobile frame also includes a constraint cylinder, which is fixedly connected to the connecting frame. The crossbeam of the reciprocating frame passes through the constraint cylinder. An elastic slider is provided between the constraint cylinder and the reciprocating frame. The elastic slider causes the reciprocating frame to be subjected to a downward force, so that the force between the scraper and the concrete surface is always appropriate and does not change too much.

[0012] Furthermore, the connecting transverse plate is provided with a slide groove at a position corresponding to the connecting head, and the end of the connecting head can slide up and down in the slide groove to isolate the vibration of the connecting head.

[0013] Furthermore, the bottom inner surface of the constraint cylinder is provided with two groups of limiting inclined planes, and a sliding inclined plane that can slide is movably connected between the two groups of limiting inclined planes. Inclines are provided on both sides of the sliding inclined plane. The reciprocating frame is provided with a protrusion corresponding to the sliding inclined plane. When the protrusion moves with the reciprocating frame, the protrusion pushes the sliding inclined plane to move synchronously. When the sliding inclined plane is blocked by the limiting inclined plane, the protrusion moves to the top along the inclined plane of the sliding inclined plane.

[0014] Furthermore, the scraper is provided with a parallel section corresponding to the connection between the vibrator and the plate, and the inclined sections on both sides of the parallel section are inclined in opposite directions. One side of the parallel section is parallel to the plate, and the other side is set as an arc surface, which is tangent to the adjacent inclined section.

[0016] The present application provides a fiber concrete vibrator for residential garage construction, in which a motor and a second transmission unit drive a vibrator to cause the vibrator to vibrate, and the motor is arranged on a buffer platform. Compared with directly using a vibration motor, on the one hand, the motor and the vibrator generate heat separately and do not overlap each other, and their respective operating temperatures are relatively low; on the other hand, the motor is in an environment with relatively small vibration during operation, thereby increasing its service life.

[0017] Secondly, a scraper is provided in front of the flat plate, which reciprocates to spread the concrete in front. Even if it is not spread flat, it can ensure that the concrete at the connection between the flat plate and the vibrator is relatively thick, so that the bottom of the connection between the flat plate and the vibrator will not be suspended in the air, which not only ensures the vibration effect, but also reduces the probability of deformation of the flat plate.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] For example, see Figure 1 and Figure 2 A fiber concrete vibrator for residential garage construction, hereinafter referred to as the vibrator, includes a flat plate 1, a connecting frame 3 is provided on the flat plate 1, the flat plate 1 is connected to a motor 7 through a buffer platform, the buffer platform is composed of a support plate, a guide rod and a spring, the support plate is movably connected to the flat plate 1 through the guide rod, the spring is arranged between the support plate and the flat plate 1, the motor 7 is mounted on the support plate, the motor 7 is connected to the vibrator 2 through a second transmission unit 8, the vibrator 2 is provided with an eccentric block, the eccentric block rotates to generate vibration, the second transmission unit 8 is configured to isolate vibration, the motor 7 is connected to a moving frame 4 through a first transmission unit 6, the bottom of the moving frame 4 is connected to a scraper 5, the scraper 5 It has at least one inclined section, the moving frame 4 is movably connected to the connecting frame 3, the first transmission unit 6 drives the moving frame 4 and the scraper 5 to make a reciprocating linear motion forward and backward, and the scraper 5 smoothes the concrete in front of the flat plate 1 when moving, so that the occurrence rate of hanging is reduced when the flat plate 1 is vibrated. At the same time, the motor 7 is separated from the vibrator 2, and the heat generated by the motor operation and the vibration will not be superimposed, which not only isolates the vibration, but also reduces the heat generation, thereby increasing the service life of the vibrator. The connecting frame 3 is also fixedly connected with a handrail to facilitate the control of the movement of the vibrator. Since the vibration frequency is relatively high, in order to avoid the moving frequency of the moving frame 4 and the scraper 5 being too high, a speed reduction mechanism is provided between the first transmission unit 6 and the motor 7 ( Figure 1 and Figure 2 Speed ​​reduction mechanism not shown).

[0028] The first transmission unit 6 includes a crank 65 that is transmission-connected to the output shaft of the motor 7. In this embodiment, the crank 65 is fixedly mounted on the output shaft, and the crank 65 is movably connected to a connecting rod 64. The connecting frame 3 is fixedly connected to a guide cylinder 62, and a moving rod 63 is movably connected to the guide cylinder 62. The guide cylinder 62 guides the movement of the moving rod 63. A connector 61 is provided at the end of the moving rod 63, and the connector 61 is movably connected to the moving frame 4. Please refer to Figure 3 The movable frame 4 is provided with a slide groove corresponding to the position of the connector 61, and the end of the connector 61 can slide up and down in the slide groove. When the connecting frame 3 vibrates up and down with the flat plate 1, the first transmission unit 6 will vibrate synchronously with the connecting frame 3, and the connector 61 can prevent the movable frame 4 from vibrating up and down with the connecting head 61.

[0029] See also Figure 1 and Figure 4 The second transmission unit 8 includes a driving wheel 81 that is transmission-connected to the output shaft of the motor 7 and a transmission shaft 82 that is transmission-connected to the input shaft of the vibrator 2. In this embodiment, the driving wheel 81 is fixedly connected to the output shaft of the motor 7, and the transmission shaft 82 is fixedly connected to the input shaft of the vibrator 2. The transmission shaft 82 is fixedly connected to a driven wheel 83. The driving wheel 81 is transmission-connected to the driven wheel 83 through a transmission belt. A pressure wheel 86 is provided on one side of the transmission belt. The pressure wheel 86 presses the transmission belt so that the transmission belt always maintains an appropriate tension. In this embodiment, a connecting ring 84 is fixedly connected to the housing of the motor 7, and a pressure ring 85 is movably connected to the connecting ring 84. The pressure wheel 86 is provided on the pressure ring 85. A torsion spring is provided between the pressure ring 85 and the connecting ring 84 to make the pressure wheel 86 move toward the transmission belt. As the plate 1 vibrates, the plate 1 and the motor 7 move asynchronously, and the distance between the driving wheel 81 and the driven wheel 83 will change. However, under the pressure of the pressure wheel 86, the tension of the transmission belt is always appropriate.

[0030] See also Figure 1 , Figure 5 and Figure 6 The movable frame 4 includes a reciprocating frame 41, which is in the shape of a letter "Π". The reciprocating frame 41 is configured to stand independently. The reciprocating frame 41 has two front and rear standing legs. The front standing leg is located in front of the flat plate 1, and the front standing leg is fixedly connected to the scraper 5. The rear standing leg is located behind the flat plate 1, and the rear standing leg is fixedly connected to the sliding plate 42. The reciprocating frame 41 is fixedly connected with a connecting cross plate 43, and the connecting cross plate 43 is connected to the first transmission unit 6. The first transmission unit 6 pushes the reciprocating frame 41 to move forward and backward through the connecting cross plate 43, thereby pushing the scraper 5 to move forward and backward, and leveling the concrete in front of the flat plate 1.

[0031] The movable frame 4 also includes a constraint cylinder 44, which is fixedly connected to the connecting frame 3. The crossbeam of the reciprocating frame 41 passes through the constraint cylinder 44. An elastic slider 45 is provided between the constraint cylinder 44 and the reciprocating frame 41. The elastic slider 45 causes the reciprocating frame 41 to be subjected to a downward force, so that the force between the scraper 5 and the sliding plate 42 and the concrete surface is appropriate. When the constraint cylinder 44 vibrates up and down with the flat plate 1, the reciprocating frame 41 does not move up and down with the constraint cylinder 44. At the same time, the elastic slider 45 prevents a significant change in the force of the scraper 5 on the concrete.

[0032] The inner surface of the bottom of the restraining cylinder 44 is provided with two groups of limiting inclined surfaces 46, and a sliding inclined surface 47 is movably connected between the two groups of limiting inclined surfaces 46. The reciprocating frame 41 is provided with a protrusion 48 corresponding to the sliding inclined surface 47. When the protrusion 48 moves with the reciprocating frame 41, the protrusion 48 pushes the sliding inclined surface 47 to move synchronously. When the sliding inclined surface 47 is blocked by the limiting inclined surface 46, the protrusion 48 moves along the inclined surface of the sliding inclined surface 47, so that the reciprocating frame 41 is lifted, the scraper 5 is out of contact with the concrete, and the protrusion 48 Moving along the top of the sliding slope 47 and along with the other side of the sliding slope 47, the scraper 5 is lowered in height and contacts the concrete. At this time, the reciprocating frame 41 moves in the opposite direction, and the protrusion 48 pushes the sliding slope 47 to move toward the other side of the sliding slope 47. That is, each time the scraper 5 pushes the concrete, when approaching the dead point, the scraper 5 is lifted over the concrete accumulated in front of the scraper 5 and then falls down. After the scraper 5 falls, it scrapes the accumulated concrete in the opposite direction to make the concrete in front of the flat plate 1 flat.

[0033] See also Figure 1 and Figure 2 The scraper 5 is provided with a parallel section corresponding to the connection between the vibrator 2 and the flat plate 1. The inclined directions of the inclined sections on both sides of the parallel section are opposite. One side of the parallel section is parallel to the flat plate 1, and the other side is set as an arc surface. The arc surface is tangent to the adjacent inclined section. When the scraper 5 reciprocates, the parallel side of the parallel section can gather concrete, and the arc surface on the other side can push the gathered concrete away. This can ensure that the parallel section can gather concrete, the position where the parallel section passes will not be a low-lying place, the bottom of the connection between the flat plate 1 and the vibrator 2 will not be suspended, and it can also avoid the accumulation of too much concrete, making the area too thick and affecting the vibration efficiency.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
