It mainly consists of a vibration table, a control system, test molds, and supports. By adjusting the vibration frequency and amplitude, this apparatus studies the compactness and fluidity of concrete under different vibration parameters and their impact on the forming quality of components. It is widely used in optimizing concrete material properties, improving construction processes, and formulating and validating relevant standards.

[0003] According to a public announcement of a cement mortar test vibrating device (announcement number: CN221365145U), the above application includes a workbench, with legs fixedly connected to the four corners of the bottom outer wall of the workbench, a material collection vibration mechanism provided on the top outer wall of the workbench, a base plate provided at both ends of the top outer wall of the workbench, a transverse moving mechanism between the base plate and the workbench, a side plate provided on the top of the base plate, and a cross plate provided between the two ends of the side plate.

[0004] However, in actual use, the above-mentioned vibrating device can only be adjusted laterally, and then the vibrating rod is controlled to move and compact the material inside the aggregate box at different heights in the longitudinal direction. The longitudinal sides of the aggregate box are difficult to be fully vibrated, resulting in local looseness and insufficient compaction, which affects the test results. In view of this, we propose a movable frame-type concrete vibration test device. Utility Model Content

[0005] The purpose of this invention is to provide a movable frame-type concrete vibration test device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a movable frame-type concrete vibration test device, comprising a frame, a three-axis servo module fixedly connected to the top end face of the frame, casters fixedly connected to the bottom end face of the frame, a mounting frame fixedly connected to the output end of the three-axis servo module, and a vibration assembly provided on the inner wall of the mounting frame, the vibration assembly comprising:

[0013] Preferably, the side wall of the mounting bracket is provided with a guide groove, an electric push rod is fixedly connected to the side wall of the mounting bracket, and the output shaft of the electric push rod is fixedly connected to a guide frame.

[0014] Preferably, the inner wall of the guide frame abuts against the outer wall of the mounting block, and the outer wall of the mounting block is slidably connected to the inner wall of the guide groove, so that the electric push rod pushes the guide frame to move laterally, thereby causing the mounting block to move laterally in the guide groove, and thus adjusting the tilt angle of the vibrator before and after.

[0015] Compared with the prior art, this utility model provides a movable frame-type concrete vibration test device, which has the following beneficial effects:

[0016] 1. This movable frame-type concrete vibration test device, through its set vibration components and adjustable tilt angles of the vibrator, can enhance the compaction of the concrete mold corner areas. The vibration influence range expands in a fan shape, and the sweeping vibration covers a larger area, reducing blind spots and optimizing the vibration process. The rubber sleeve prevents direct contact between the mold and the vibrator from causing the vibrator to rebound and shake, affecting vibration stability. The rubber sleeve provides soft contact and buffers impact force, protecting the equipment and materials. The steel ball transforms the sliding friction between the slider and the slide rod into rolling friction, making the slider move more easily on the slide rod. It adapts to the curvature changes of the slide rod, always maintaining smooth contact and ensuring the continuity and smoothness of the vibrator's movement at different angles.

[0017] 2. This movable frame-type concrete vibration test device, through the electric push rod and guide frame, adjusts the front and rear tilt angles of the vibrator, and in conjunction with the adjustment of the left and right tilt angles of the vibrator, is particularly suitable for dealing with dead corners, edges or areas where reinforcing bars intersect in concrete molds. Without changing the insertion point, a wider range of vibration effect can be achieved by adjusting the angle. Attached Figure Description

Detailed Implementation

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a movable frame-type concrete vibration test device, including a frame 1, a three-axis servo module 2 fixedly connected to the top end face of the frame 1, a caster wheel 3 fixedly connected to the bottom end face of the frame 1, a mounting frame 4 fixedly connected to the output end of the three-axis servo module 2, and a vibration component 5 provided on the inner wall of the mounting frame 4. The vibration component 5 includes a slide rod 501, a slider 502, a vibrating rod 503, a rubber sleeve 504, a mounting block 505, a motor 506, a reciprocating screw 507, a threaded block 508, a hinge rod 509, and a steel ball 510.

[0024] In one embodiment of this utility model, the slide rod 501 is fixedly connected to the inner wall of the mounting frame 4, the vibrating rod 503 is fixedly connected to the external control circuit, the slide rod 501 is arc-shaped, and a slider 502 is provided on the side wall of the slide rod 501. The slider 502 slides on the side wall of the slide rod 501, thereby adjusting the left and right tilt angle of the vibrating rod 503. A steel ball 510 is movably connected to the inner wall of the slider 502. The vibrating rod 503 is fixedly connected to the bottom end face of the slide rod 501, and a rubber sleeve 504 is sleeved on the bottom end face of the vibrating rod 503.

[0025] A motor 506 is fixedly connected to the side wall of the mounting block 505. A reciprocating screw 507 is fixedly connected to the output end of the motor 506. A threaded block 508 is threadedly connected to the side wall of the reciprocating screw 507. A hinge rod 509 is sleeved on the bottom of the threaded block 508. The hinge rod 509 is hinged to the slider 502. There are two sets of hinge rods 509, and the two sets of hinge rods 509 are symmetrically arranged on the top end face of the slider 502.

[0026] The caster wheel 3 is equipped with a locking device, and the drive device inside the vibrating rod 503 integrates power, frequency, and current monitoring sensors.

[0027] The three-axis servo module 2 is controlled by a control device to achieve three-axis coordinate movement control of the vibrator 503. The vibrator 503 is fixed below the Z-axis sliding arm of the three-axis servo module 2. Coordinate locators are fixedly installed on one side of the frame 1 at the bottom of the frame. A certain bottom corner is defined as the origin of the coordinate system. The dehumidification position of the two locators is the bottom corner. A fixing plate 6 is fixedly connected to the side wall of the mounting frame 4. A camera and a laser rangefinder are fixedly connected to the bottom end face of the fixing plate 6. The camera is used to record the working status of the vibrator 503 and the morphological changes of the concrete material surface. The laser rangefinder is used to measure the distance between the lower end of the Z-axis sliding arm and the concrete material.

[0028] When the concrete mold is placed inside the frame 1, the coordinate locator is moved along the bottom edge of the frame 1 to the initial point where vibration work needs to be carried out, and the coordinates of this position are determined. The coordinates of this point are then input into the display interface of the control device. The control console can perform single-axis control on the three-axis servo module 2. First, the vibrator 503 is moved above the mold. Then, based on the distance measured by the laser rangefinder, the descent coordinates are input, and the vibrator 503 is controlled to move downwards until it is inserted into the concrete. The vibrator 503 is driven to work through the control device to achieve fixed-point vibration. Moving the vibrator 503 means that the vibrator 503 works along a certain path. Moving vibration also includes dispersed vibration, that is, when the vibrator 503 moves from a certain point to the next point, it first pulls out the concrete and then continuously vibrates, that is, the vibrator 503 is always in the concrete during the movement.

[0029] The motor 506 is started, causing the reciprocating screw 507 to rotate. The threaded block 508 moves linearly along the reciprocating screw 507, which in turn drives the slider 502 to move laterally along the slide rod 501. The slide rod 501 is arc-shaped. Adjusting the tilt angle of the vibrator 503 can enhance the compaction of the corner areas of the concrete mold. When the drive motor 506 continues to rotate, the threaded block 508 and the slider 502 move laterally back and forth under the guidance of the reciprocating screw 507. The vibration influence range expands in a fan shape, and the sweeping vibration covers a larger area, reducing the compaction blind spots and optimizing the vibration process.

[0030] A rubber sleeve 504 is fitted onto the bottom end face of the vibrator 503 to prevent the vibrator 503 from directly contacting the inner wall or bottom of the device mold. This avoids direct contact between the mold and the vibrator 503, which could cause the vibrator 503 to rebound or vibrate, affecting vibration stability. The rubber sleeve 504 provides soft contact and cushions impact, protecting the equipment and materials. A steel ball 510 is movably connected to the inner wall of the slider 502. The steel ball 510 is movably connected to the slide rod 501. The steel ball 510 converts the sliding friction between the slider 502 and the slide rod 501 into rolling friction, making the movement of the slider 502 on the slide rod 501 easier. Since the slide rod 501 has an arc-shaped structure, the trajectory of the slider 502 when it moves on it is curved. Using the steel ball 510 as the contact medium can adapt to changes in track curvature, always maintaining smooth contact and ensuring the continuity and smoothness of the vibrator 503 in different angles of movement.

[0031] In addition, the side wall of the mounting frame 4 is provided with a guide groove 7, and an electric push rod 8 is fixedly connected to the side wall of the mounting frame 4. The output shaft of the electric push rod 8 is fixedly connected to a guide frame 9. The inner wall of the guide frame 9 abuts against the outer wall of the mounting block 505, and the outer wall of the mounting block 505 is slidably connected to the inner wall of the guide groove 7. This allows the electric push rod 8 to push the guide frame 9 to move laterally, thereby causing the mounting block 505 to move laterally within the guide groove 7. This adjusts the tilt angle of the vibrator 503. Combined with the adjustment of the tilt angle of the vibrator 503 in the left and right directions, it is particularly suitable for dealing with dead corners, edges, or areas where reinforcing bars intersect in concrete molds. Without changing the insertion point, a larger range of compaction effect can be achieved by adjusting the angle.

[0032] In this invention, during use, the motor 506 drives the reciprocating screw 507 to rotate, the threaded block 508 moves linearly along the reciprocating screw 507, and the slider 502 moves laterally along the slide rod 501. Adjusting the tilt angle of the vibrator 503 can enhance the compaction of the corner area of ​​the concrete mold, expand the vibration influence range in a fan shape, and cover a larger area with sweeping vibration, reducing blind spots in compaction. The bottom end face of the vibrator 503 is fitted with a rubber sleeve 504 to prevent direct contact between the mold and the vibrator 503, which would cause the vibrator 503 to rebound or shake, affecting vibration stability. The inner wall of the slider 502 is movably connected with a steel ball 510, which is movably connected to the slide rod 501. The steel ball 510 converts the sliding friction between the slider 502 and the slide rod 501 into rolling friction, making the movement of the slider 502 on the slide rod 501 easier and ensuring the continuity of the vibrator 503 in different angle movements.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
