Abstract
Description
Technical Field
[0001] This utility model relates to a novel concrete leveling device, belonging to the field of concrete construction technology. Background Technology
[0002] In building construction, cast-in-place concrete is widely used due to its convenience and good integrity. After the concrete pouring is completed, the ground needs to be leveled. This process typically involves two main steps: first, using vibrating equipment to thoroughly compact the concrete to ensure its density and strength; then, using a leveling tool to smooth the concrete surface to meet the design requirements for flatness. This construction method effectively guarantees the construction quality and surface appearance of the concrete structure.
[0003] The utility model patent with patent number 202422536078.7 discloses a flatness control device for cast-in-place concrete floor slabs, comprising: a bracket having a support beam and a plurality of retractable support legs connected to the support beam; a slide rod having its upper end mounted on the support beam and being movable along the axis of the support beam; a scraper connected to the lower end of the slide rod, the lower end surface of the scraper having a flat scraping surface; and a scraper driving mechanism mounted on the bracket and connected to the slide rod, which is used to drive the slide rod to move along the axis of the support beam.
[0004] Although the aforementioned patent can achieve the function of leveling cast-in-place concrete slabs, the current technology is not comprehensive and has the following drawbacks: Currently, in the field of concrete construction and paving equipment, it is impossible to realize precise height adjustment of the screed plate device, which directly affects the road surface smoothness and construction quality.
[0005] To solve one of the above problems, a new type of concrete leveling device is urgently needed. Utility Model Content
[0006] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to achieve precise lifting and lowering control of the scraper plate by adjusting the height of the horizontal beam through the adjustment mechanism, so as to meet the position adjustment requirements of the scraper plate device. To this end, a new type of concrete leveling device is provided.
[0007] The novel concrete leveling device of this utility model includes a frame and horizontally arranged side rails A and B. One end of the frame is equipped with a set of traveling wheels A that can travel along side rail A, and the other end of the frame is equipped with a set of traveling wheels B that can travel along side rail B. The device is characterized by further including a scraper plate, on which at least two sets of vertical slides and at least two sets of vibration motors are installed. The frame has a horizontal beam for connecting with the vertical slides, and the frame is equipped with a fine-tuning mechanism for adjusting the height of the horizontal beam.
[0008] In concrete construction, ground leveling, or paving equipment, the precise height adjustment of the screed plate device is crucial for construction quality. The frame moves bidirectionally along side rails A and B via traveling wheel sets A and B respectively. A vibrating motor drives the screed plate to generate high-frequency vibration. The screed plate moves with the frame and acts on the cast-in-place concrete, enabling rapid leveling of the concrete surface. Furthermore, a fine-tuning mechanism adjusts the height of the horizontal beam, which in turn drives the vertical slide to achieve precise lifting and lowering control of the screed plate, meeting the position adjustment needs of the screed plate device and offering convenient adjustment. The fine-tuning mechanism allows for on-demand adjustment of the screed plate height before construction to better control the paving thickness and ensure consistent paving thickness across the entire cross-section.
[0009] Preferably, the vertical carriage is provided in two sets at intervals, namely the first vertical lifting column and the second vertical lifting column, and the horizontal beam is provided in two sets accordingly, namely horizontal beam A and horizontal beam B.
[0010] Preferably, the first vertical lifting column passes through the horizontal beam A, and an upper baffle A and a lower retaining ring A are installed on the first vertical lifting column. An upper compression spring A is sleeved on the first vertical lifting column between the upper baffle A and the horizontal beam A, and the upper compression spring A provides the upward thrust of the first vertical lifting column. A lower compression spring A is sleeved on the first vertical lifting column between the lower retaining ring A and the horizontal beam A, and the lower compression spring A provides the downward thrust of the first vertical lifting column. The second vertical lifting column passes through the horizontal beam B, and an upper baffle B and a lower retaining ring B are installed on the second vertical lifting column. An upper compression spring B is sleeved on the second vertical lifting column between the upper baffle B and the horizontal beam B. A lower compression spring B is sleeved on the second vertical lifting column between the lower retaining ring B and the horizontal beam B. The first vertical lifting column passes through the horizontal beam A and can slide with the horizontal beam A. It does not affect the high-frequency vibration generated by the vibrating motor driving the scraper plate. In addition, the setting of the compression spring avoids the over-vibration or under-vibration caused by the traditional rigid connection.
[0011] Preferably, the frame is equipped with a first vertical column, a second vertical column, and a third vertical column. Horizontal beam A is positioned between the first and second vertical columns, and horizontal beam B is positioned between the second and third vertical columns. A first slider and a second slider are respectively installed at both ends of horizontal beam A, and a third slider and a fourth slider are respectively installed at both ends of horizontal beam B. A first vertical rail that slides in conjunction with the first slider is provided on the first vertical column, a second vertical rail that slides in conjunction with the second slider is provided on the second vertical column, a third vertical rail that slides in conjunction with the third slider is provided on the second vertical column, and a fourth vertical rail that slides in conjunction with the fourth slider is provided on the third vertical column. When horizontal beam A needs to be adjusted, both ends of horizontal beam A move along the length of the first and second vertical rails respectively to prevent skewness.
[0012] Preferably, the height fine-tuning mechanism is provided in four sets: a first adjustment mechanism installed on the first vertical column, a fourth adjustment mechanism installed on the third vertical column, and a second and third adjustment mechanisms symmetrically installed on the second vertical column.
[0013] Preferably, the first adjustment mechanism includes a support plate for mounting the bottom end of the first vertical column. A threaded rod is provided between the support plate and the frame. The threaded rod passes through the horizontal beam A, and a lower locking nut and an upper locking nut are threadedly connected to the threaded rod on both sides of the horizontal beam A, respectively. The method for adjusting the raising of the horizontal beam A is as follows: the threaded rod is fixed and will not rotate. First, the upper locking nut is rotated clockwise using a wrench to adjust its position upwards. Then, the lower locking nut is rotated clockwise using a wrench. The lower locking nut engages with the threaded rod, causing the horizontal beam A to rise relative to the threaded rod until it is adjusted to a suitable position. The lower and upper locking nuts can then be used to fix the horizontal beam A again. The first, second, third, and fourth adjustment mechanisms need to be adjusted synchronously.
[0014] Preferably, the first adjustment mechanism, the second adjustment mechanism, the third adjustment mechanism, and the fourth adjustment mechanism have the same structure.
[0015] Preferably, the horizontal beam A is provided with a sliding sleeve A that cooperates with the first vertical lifting column, and the horizontal beam B is provided with a sliding sleeve B that cooperates with the second vertical lifting column.
[0016] Preferably, four sets of vibration motors are provided, respectively located on both sides of the first vertical lifting column and the second vertical lifting column. The symmetrical arrangement of vibration motors results in a more uniform distribution of excitation force after height adjustment, thus improving the uniformity of compaction.
[0017] Preferably, the side rail A is an I-beam guide rail, and the side rail A includes at least two sets of track wheels. The frame is driven by an electric winch mechanism in conjunction with a traction steel wire rope.

A vibrating motor drives a scraper plate to generate high-frequency vibration. The scraper plate moves with the frame and acts on the cast-in-place concrete, which can quickly achieve the leveling operation of the concrete surface. In addition, the fine-tuning mechanism adjusts the height of the horizontal beam, which drives the vertical slide to achieve precise lifting and lowering control of the scraper plate, meeting the position adjustment requirements of the scraper plate device, and the adjustment is relatively convenient.
[0020] The novel concrete leveling device described in this utility model has a fine-tuning mechanism that allows for adjustment of the scraper plate height as needed before construction, so as to better control the paving thickness and ensure consistent paving thickness across the entire cross-section.
[0021] The novel concrete leveling device of this utility model has a first vertical lifting column that penetrates through the horizontal beam A and can slide with the horizontal beam A. This does not affect the high-frequency vibration generated by the vibrating motor driving the scraper plate. Furthermore, the setting of the compression spring avoids the over-vibration or under-vibration caused by traditional rigid connections. Attached Figure Description

The scraper plate 6 moves with the frame 1 and acts on the cast-in-place concrete, enabling rapid leveling of the concrete surface. Furthermore, a fine-tuning mechanism adjusts the height of the horizontal beam, which in turn drives the vertical slide 7 to precisely control the lifting and lowering of the scraper plate 6, meeting the position adjustment requirements of the scraper plate device and offering convenient adjustment.

[0033] Furthermore, referring to Figure 3 The first vertical lifting column passes through the horizontal beam A16. An upper baffle A22 and a lower retaining ring A23 are installed on the first vertical lifting column. An upper compression spring A24 is sleeved on the first vertical lifting column between the upper baffle A22 and the horizontal beam A16, providing upward thrust for the first vertical lifting column.

It does not affect the high-frequency vibration generated by the vibration motor 8 driving the scraper plate 6. In addition, the setting of the compression spring avoids the over-vibration or under-vibration caused by the traditional rigid connection.
[0034] Furthermore, the frame 1 is equipped with a first vertical column 9, a second vertical column 10, and a third vertical column 11. A horizontal beam A16 is positioned between the first vertical column 9 and the second vertical column 10, and a horizontal beam B17 is positioned between the second vertical column 10 and the third vertical column 11.

First, use a wrench to rotate the upper locking nut 18.4 clockwise to adjust the position of the upper locking nut 18.4 upward. Then, use a wrench to rotate the lower locking nut 18.3 clockwise.
