Description

Technical Field

[0001] The present invention relates to the technical field of concrete planing, in particular to a concrete planing device. Background Art

[0002] During the construction process, precast concrete parts are widely used in various structures. In order to meet the needs of subsequent pre-buried cables, water pipes, etc., it is usually necessary to plane and groove the precast concrete parts.

[0003] Traditional planing devices mostly use handheld grooving planing tools to perform grooving operations manually. In actual operation, construction workers hold the planing tools and plan along the surface of the prefabricated parts while moving. This method ensures construction flexibility to a certain extent, but it also brings many problems.

[0004] However, this handheld planing method is difficult to guarantee planing accuracy and quality. The instability and subjectivity of manual operation make it difficult to achieve uniform depth and width of the planed trough, which can easily lead to irregular or broken troughs. Specifically, during the planing process, the planing tool may deviate from the predetermined planing trajectory due to hand shaking or uneven force of the operator, resulting in uneven trough edges and uneven trough bottoms. When planing harder concrete, the instantaneous impact force may cause the concrete at the edge of the trough to crack or peel off, which not only affects the appearance quality of the prefabricated part, but also may reduce its structural strength and even lead to the scrapping of the prefabricated part, increasing construction costs and the risk of project delays.

[0031] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale.

[0032] Reference Figure 1-Figure 7This embodiment provides a concrete planing device, including a planing unit 1. A planing wheel 11 is installed at the output end of the planing unit 1. A processing fixed platform 12 is fixedly installed on the outer side of the planing wheel 11. A transport guide rail 13 is laid on the bottom side of the planing wheel 11. The planing unit 1 serves as the power source of the entire device. The power components such as the motor inside it provide strong and stable power for the rotation of the planing wheel 11, ensuring that the planing wheel 11 can plan the concrete prefabricated parts at an appropriate speed and force. The material and structure of the planing wheel 11 are also carefully designed to meet the planing requirements of concrete, a relatively hard material, to ensure the efficiency of the planing process. and accuracy, and the processing fixed platform 12 on one side of the outside provides a strong support for the stability of the entire planing process, so that the planing wheel 11 can maintain a stable position and posture during the rotating planing. During the planing process, the transport guide rail 13 is not only a channel for the movement of the precast concrete parts, but also plays a role in guiding and positioning, so that the precast concrete parts can accurately enter the working area of ​​the planing wheel 11, ensuring the smooth progress of the planing operation. The selection of its material also takes into account wear resistance and durability to cope with long-term use and friction of the precast concrete parts; a set of rotating wheels 2 are installed at both ends of the planing wheel 11, and the rotating wheels 2 are connected to the planing wheel 11 on a transmission shaft On the upper surface, the outer ring of the rotating wheel 2 is provided with a slide groove 21, and the interior of the slide groove 21 is provided with a friction contact groove 22. The inner wall of the friction contact groove 22 is movably connected with a connecting rod 23 through a pin shaft. The processing fixed platform 12 is penetrated by the sliding rod 24, and the top of the sliding rod 24 is movably connected to the other end of the connecting rod 23 through a pin shaft. The bottom end of the sliding rod 24 is installed with a pressing plate 25, and the bottom of the pressing plate 25 is installed with multiple groups of rollers 26, and the top of the pressing plate 25 is connected to the bottom of the processing fixed platform 12 through a return spring 27. When the planing work is performed, the transport guide rail 13 moves one end of the concrete precast part to the bottom side of the planing wheel 11. At this time, the planing unit 1 drives the planer As the cutting wheel 11 rotates, the rotating wheel 2 also gradually rotates. During the rotation, its continuous rotation causes the friction contact groove 22 to exert a downward force on the connecting rod 23, thereby causing the connecting rod 23 to drive the sliding rod 24 to move downward. The movement of the sliding rod 24 drives the pressing plate 25 to move, thereby causing the rollers 26 of the pressing plate 25 to contact the bottom of the precast concrete part. At this time, multiple groups of rollers 26 are distributed at both ends of the planing wheel 11, so that the precast concrete parts on both sides of the planing trough body are pressed and supported by the rollers 26, so that the planing groove of the precast concrete part is more stable when subjected to force and is not prone to collapse, thereby effectively improving the effect of the concrete planing trough body and ensuring the planing quality.

[0033] Specifically, there is a moving friction force between the friction contact groove 22 and the pin of the connecting rod 23. When the rotating wheel 2 rotates, the rotation force applies a bending force to the connecting rod 23, and the bending force applies downward pressure to the sliding rod 24.

[0034] Furthermore, a scraper 3 is installed at the bottom of the processing fixed table 12, and one side of the scraper 3 is a V-shaped guide groove. A baffle 32 is installed at the bottom of the processing fixed table 12. A scraper 3 is installed at the bottom of the processing fixed table 12, and one side of the scraper 3 is a V-shaped guide groove. The design of the V-shaped guide groove is conducive to collecting the debris generated by planing and guiding it into the collection frame 43, thereby improving the cleaning efficiency. A baffle 32 is installed at the bottom of the processing fixed table 12, and the position and shape of the baffle 32 are carefully designed to block the debris splashed by planing to the greatest extent, protect the safety of the operator, and maintain the cleanliness of the working environment.

[0035] Furthermore, the scraper 3 is located on one side of the processed prefabricated concrete part, and the baffle 32 is located on the side of the unshaved concrete. The baffle 32 blocks the shaved debris, while the scraper 3 cleans the shaved debris.

[0036] Furthermore, a set of support rails 4 are installed in the vertical direction of the transport guide rail 13, a broken rail 41 is installed on the top of the support rail 4, two sets of support blocks 42 are installed on the top of the support rail 4, and one set of support blocks 42 is connected to the bottom side of the broken rail 41, and the support block 42 is movably connected to the collection frame 43 at the top of the pin shaft, and support plates 44 are placed on the opposite sides of the collection frame 43. A set of support springs 45 are installed on the outer wall of the support plate 44, and a rocker 46 is installed on the side of the broken rail 41 of the transport guide rail 13. The support springs of the support plate 44 are connected to the bottom side of the broken rail 41. The spring 45 is used to keep the collecting frame 43 in a horizontal position. During the movement and collection of debris by the collecting frame 43, the support spring 45 can provide a stable supporting force to ensure that the collecting frame 43 will not affect the debris collection effect due to shaking or tilting. The transport guide rail 13 has a gap at the far end of the planing stroke, and the gap is filled by the broken rail 41. The planing debris is discharged through the gap. This design not only ensures the functional integrity of the transport guide rail 13, but also provides a convenient channel for the discharge of debris, thereby realizing the smooth discharge and collection of debris.

[0037] Furthermore, the support spring 45 of the support plate 44 is used to keep the collecting frame 43 in a horizontal position, and the transport guide rail 13 has a gap at the far end of the planing stroke, which is filled by the broken rail 41, and the planing debris is discharged through the gap.

[0038] Furthermore, a pulling assembly 5 is installed at one end of the support rail 4 . The pulling assembly 5 includes a first steering wheel 51 installed at one end of the support rail 4 . A first pull rope 52 is installed on the first steering wheel 51 .

[0039] Furthermore, one end of the first pull rope 52 is connected to the side wall of a group of pressing plates 25, and the other end of the first pull rope 52 is connected to one end of the broken rail 41. When not processed, the first pull rope 52 pulls the collection frame 43 out of the transport guide rail 13.

[0040] Furthermore, the transport rail 13 is provided with a restoration component 6 on the opposite side of the pulling component 5. The restoration component 6 includes a second steering wheel 61 installed on one side of the transport rail 13. A second pull rope 62 is installed on the second steering wheel 61. During processing, the second pull rope 62 pulls the collection frame 43 so that the collection frame 43 enters the transport rail 13.

[0041] Furthermore, the first steering wheel 51 and the second steering wheel 61 have different winding directions for the first pull rope 52 and the second pull rope 62, thereby achieving different pulling directions. The first steering wheel 51 and the second steering wheel 61 have different winding directions for the first pull rope 52 and the second pull rope 62, thereby achieving different pulling directions. This design cleverly utilizes the steering function of the steering wheel to convert the force of the pull rope into movement in different directions, thereby achieving different actions of the collection frame 43 when collecting debris and discharging debris.

[0042] Operation process: During the planing work, the transport guide rail 13 moves one end of the concrete precast part to the bottom side of the planing wheel 11. At this time, the planing unit 1 drives the planing wheel 11 to rotate. At this time, the rotating wheel 2 also gradually rotates. During the rotation, its continuous rotation causes the friction contact groove 22 to exert a downward force on the connecting rod 23, thereby causing the connecting rod 23 to drive the sliding rod 24 to move downward. The movement of the sliding rod 24 drives the pressing plate 25 to move, thereby causing the roller 26 of the pressing plate 25 to contact the bottom of the concrete precast part. At this time, multiple groups of rollers 26 are distributed on the planing wheel 11. At both ends, the concrete prefabricated members on both sides of the planing trough are pressed and supported by the rollers 26, so that the planing trough of the concrete prefabricated member is not easily damaged, which effectively improves the effect of the concrete planing trough; and at this time, the baffle 32 is located on the side where the planing wheel 11 does not plane the concrete prefabricated member, which blocks the debris splashed by planing, improves safety, and avoids debris on the transport guide rail 13. At this time, the trough body after the concrete prefabricated member is planed is full of debris, which drives the scraper 3 of the V-groove to scrape the upper horizontal surface of the concrete prefabricated member and the inside of the planing trough. The scraper 3 pushes the debris accumulated at the terminal of the concrete precast part into the collecting frame 43, and the debris on the concrete precast part is cleaned. During the planing process, the downward movement of the pressing plate 25 pulls the second pull rope 62, and the second pull rope 62 is turned by the second steering wheel 61, so that the second pull rope 62 pulls the collecting frame 43 to move between the two transport guide rails 13. During the period, it is in a state to be collected, and when the planing wheel 11 stops rotating and its pressing plate 25 recovers upward, the pressing plate 25 pulls the first pull rope 52, and the first pull rope 52 pulls the collecting frame 43 out of the gap of the transport guide rail 13, and when moving out, the collecting frame 43 passes through the upward inclined surface of the rocker 46, causing the collecting frame 43 to tilt, and then the debris in the collecting frame 43 is discharged, so that the collecting frame 43 can collect and discharge the debris in a circular manner, and also avoids the accumulation of debris between the two transport guide rails 13, reducing the workload of manual cleaning.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
