Description

Technical Field

[0001] The utility model relates to the technical field of concrete vibrators, in particular to a concrete vibrator with an adjustable vibration surface. Background Art

[0002] A concrete vibrator is a tool used to compact concrete during pouring. It uses electricity or compressed air as power to make the machine parts rotate eccentrically or reciprocate rapidly to generate vibration. This vibration helps to expel the air inside the concrete, increase the density of the concrete, and thus improve the strength and durability of the concrete. Concrete vibrators can be divided into: internal vibrators and plate vibrators.

[0003] Currently, the internal vibrator usually adjusts the vibration area by adjusting the amplitude of vibration. When the existing vibrator is in use, first insert the vibrating rod to the position where vibration is required, and then start the vibration motor set on the vibrator body. The vibrating rod is driven by the vibration motor to vibrate the concrete. However, when the existing vibrator is working, it is only supported by universal locking wheels and shock-absorbing fixing seats. During the vibration process, the vibrator may move or shift due to the unevenness of the concrete or other external force factors, resulting in uneven vibration effect, and even causing damage to the concrete and affecting the vibration effect of the concrete.

[0004] Therefore, it is necessary to provide a new concrete vibrator with an adjustable vibration surface to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a concrete vibrator with an adjustable vibration surface.

[0006] The concrete vibrator with an adjustable vibration surface provided by the utility model includes a base and a vibrator body. A support device is fixedly connected to the inner wall of the groove opened at the bottom of the base, and the vibrator body is fixedly connected to the top of the base;

[0007] The support device includes a driving component, two first double-threaded rods, and several connecting rods. One end of each of the two first double-threaded rods is rotatably connected to the inner wall of the groove opened at the bottom of the base, and the other ends of the two first double-threaded rods are respectively engaged with a second double-threaded rod through the driving component. A plurality of sliders are threadedly connected to the two first double-threaded rods and the two second double-threaded rods. One end of each of the several connecting rods is rotatably connected to the side wall of the several sliders, and the other end of the several connecting rods away from the sliding block is rotatably connected to a support block. A fixing plate is fixedly connected to the bottom of the support block, and a support frame is fixedly connected to the end of the fixing plate away from the support block.

[0008] Preferably, the driving assembly includes a driving member, a driving gear and a driven gear. The driving member is fixedly connected to the inner wall of a groove formed at the bottom of the base, and a transmission member is fixedly connected to the output end of the driving member. The driving gear is fixedly connected to one end of the first bidirectional threaded rod, and the driven gear is fixedly connected to one end of the second bidirectional threaded rod, and the driven gear meshes with the driving gear.

[0009] Preferably, the transmission member includes two rotating shafts. The two rotating shafts are respectively fixedly connected to one end of the first bidirectional threaded rod adjacent to the driving gear, and a belt is movably connected between the two rotating shafts.

[0010] Preferably, the driving member is a servo motor. The servo motor is fixedly connected to the inner wall of a groove formed at the bottom of the base, and the output end of the servo motor is fixedly connected to one end of the rotating shaft.

[0011] Preferably, a pushing handle is fixedly connected to the bottom of the vibrator body.

[0012] Preferably, a plurality of uniformly arranged universal locking wheels are fixedly connected to the bottom of the base.

[0013] Compared with the related art, a concrete vibrator with an adjustable vibration surface provided by the present utility model has the following beneficial effects:

[0014] Through the provided supporting device, when it is necessary to support the concrete vibrator, first start the driving assembly. The driving assembly drives the first bidirectional threaded rod to rotate. When the first bidirectional threaded rod rotates, it drives the driving assembly to rotate. When the first bidirectional threaded rod rotates, it will drive the second bidirectional threaded rod to rotate, and the rotation directions of the first bidirectional threaded rod and the second bidirectional threaded rod are opposite. When the first bidirectional threaded rod and the second bidirectional threaded rod rotate, the sliders provided on the first bidirectional threaded rod and the second bidirectional threaded rod move in opposite directions. By adjusting the connecting rod, the supporting block, the fixing plate and the supporting frame are lowered. The contact area between the supporting frame and the ground is much larger than the contact area between the universal wheels and the shock-absorbing fixing seat and the ground, thereby reducing the probability that the vibrator may move or shift due to the unevenness of the concrete or other external force factors, resulting in uneven vibration effect and damage to the concrete, and reducing the impact on the vibration effect of the concrete.

A support device is fixedly connected to the inner wall of the groove formed in the bottom of the base 1. The vibrator body 2 is fixedly connected to the top of the base 1. A push handle 15 is fixedly connected to the bottom of the vibrator body 2. The support device includes a drive assembly, two first bidirectional threaded rods 3 and a number of connecting rods 4. One end of each of the two first bidirectional threaded rods 3 is rotatably connected to the inner wall of the groove formed in the bottom of the base 1, and the other ends of the two first bidirectional threaded rods 3 are respectively engaged with a second bidirectional threaded rod 5 through the drive assembly. A number of sliders 6 are threadedly connected to both the two first bidirectional threaded rods 3 and the two second bidirectional threaded rods 5. One end of each of the number of connecting rods 4 is rotatably connected to the side wall of each of the number of sliders 6, and the other ends of the number of connecting rods 4 away from the sliding blocks are rotatably connected to a support block 7.
