Description

Technical Field

[0001] The invention belongs to the technical field of concrete component repair equipment, and in particular relates to a surface treatment device for repairing and reinforcing concrete components. Background Art

[0002] my country is a country with a large number of water conservancy and construction projects. Long-established water conservancy and construction projects continue to show signs of aging, rusting, and cracking of concrete structures. In addition, harmless or less harmful cracks that originally did not affect the safety of the structure gradually evolved into harmful cracks that pose safety hazards to the structure. Harmful cracks not only affect the safety of concrete structures, but also shorten the service life of concrete structures, thus posing huge safety hazards.

[0003] In order to repair concrete components, caulking or bonding FRP cloth to the surface of concrete components is usually used to delay the cracking and development of concrete cracks, or reduce the width of existing cracks, so as to achieve the purpose of strengthening concrete components with cracks and other defects.

[0004] In actual operation, the existing conventional method is that the operator first uses a handheld grinding device to clean the surface of the concrete component to expose the internal steel bars, and then performs operations such as caulking. During the above process, due to the heavy weight of the grinding equipment and the high position of the defect on the surface of the concrete component in some cases, the operator lifts the grinding equipment to process the surface of the concrete component, which is not only difficult to operate but also increases the labor intensity.

[0005] Therefore, a surface treatment device for repairing and reinforcing concrete components is provided to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0038] 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.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Example 1

[0041] Reference Figure 1-Figure 7 The present invention provides a surface treatment device for repairing and reinforcing concrete components, comprising: a base 1, with a pair of longitudinal rods 2 fixed on the top; a slide 3, which is sleeved on the pair of longitudinal rods 2 and slidably matched with the pair of longitudinal rods 2; a grinding unit 4, which is connected to the slide 3 and can move horizontally along the slide 3, and the grinding end of the grinding unit 4 is configured to grind the component surface.

[0042] Specifically, the slide 3 is installed on the longitudinal rod 2, which is supported by the inflatable telescopic unit 5. Under the action of the inflatable telescopic unit 5 and its own weight, the slide 3 can be lifted and lowered in the vertical direction along the longitudinal rod 2, thereby driving the grinding unit 4 to be lifted and lowered. The grinding unit 4 can move on the horizontal plane of the slide 3, and cooperate with the grinding end to realize the grinding treatment of the surface of the concrete component.

[0043] A pair of auxiliary movement components are respectively arranged on a pair of longitudinal rods 2 and located below the slide 3. The auxiliary movement components include an inflatable telescopic unit 5. The air inlet ends of the pair of inflatable telescopic units 5 are connected to the inflatable unit 6. The air outlet ends of the inflatable telescopic units 5 have a closed state and an open state. In the closed state, the air outlet ends of the inflatable telescopic units 5 are closed, so that the slide 3 moves upward along the longitudinal rod 2. In the open state, the air outlet ends of the inflatable telescopic units 5 are opened, and the air intake speed of the inflatable telescopic unit 5 is less than the air outlet speed of the inflatable telescopic unit 5, so that the slide 3 moves downward along the longitudinal rod 2.

[0044] Specifically, when in use, the inflatable unit 5 is inflated by the inflatable unit. When in the closed state, the inflatable unit 5 only performs the inflating operation, and the gas in the inflatable unit 5 increases, so that the inflatable unit 5 is extended, thereby driving the grinding unit 4 to move upward. When the grinding unit 4 needs to move downward, it is only necessary to switch the inflatable unit 5 to the open and closed state, the gas outlet end of the inflatable unit 5 is opened, the inflation speed of the inflatable unit 6 is lower than the gas outlet speed of the inflatable unit 5, and the gas in the inflatable unit 5 is reduced, so that the inflatable unit 5 is contracted, thereby driving the grinding unit 4 to move downward.

[0045] In the above process, the slide table 3 can be manually driven to move up or down according to actual needs to increase the lifting speed of the grinding unit 4.

[0046] In the above process, whether the grinding unit 4 moves upward or downward, it can be assisted and supported by the inflatable telescopic unit 5, thereby reducing the labor intensity.

[0047] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , further comprising: an air outlet pipe 7, which is the air outlet end of the inflatable telescopic unit 5 and is connected to the side wall of the inflatable telescopic unit 5; a valve 8, which is connected to the air outlet pipe 7 and is configured to control the opening and closing of the air outlet pipe 7.

[0048] Specifically, the air outlet pipe 7 is connected to the inflatable telescopic unit 5. When the valve 8 is opened, the inflatable telescopic unit 5 deflates through the air outlet pipe 7 to achieve contraction. When the valve 8 is closed, the inflatable telescopic unit 5 cannot deflate through the air outlet pipe 7, thereby achieving expansion.

[0049] The valves 8 on the two inflatable telescopic units 5 work synchronously to ensure that the two inflatable telescopic units 5 are telescoped synchronously.

[0050] In this embodiment, refer to Figure 1 , Figure 3 , and also includes a control switch 9 fixed on the side wall of the slide 3. The control switch 9 is connected to the valve 8 to open and close the valve 8.

[0051] Specifically, the control switch 9 can be connected to the valve 8 via a connecting wire or wirelessly, and the opening and closing of the valve 8 is achieved by operating the control switch 9. The control switch 9 is set on the side of the slide 3 away from the surface of the concrete component. When the operator operates the grinding unit 4, it is convenient to operate the control switch 9 to open and close the valve 8.

[0052] In this embodiment, refer to Figure 1 , Figure 2 , Figure 4 , and also includes: a support plate 10, which is sleeved on a pair of longitudinal rods 2 and located below the slide 3, and the bottom of the inflatable telescopic unit 5 and the inflatable unit 6 are fixed on the top surface of the support plate 10; a snap-fit ​​tool 11, which is sleeved on the longitudinal rod 2 and located below the support plate 10, and the snap-fit ​​tool 11 is configured to be fixed relative to the longitudinal rod 2 to support the support plate 10.

[0053] Specifically, under the action of the buckle fixture 11, the support plate 10 can be supported on the longitudinal rod 2. After determining the area to be processed, the support plate 10 is first moved below the area to be processed so that the grinding unit 4 matches the area to be processed. After the matching is completed, the buckle fixture 11 is installed to support the support plate 10. The support plate 10 is used to support the inflatable telescopic unit 5 so that the extension direction of the inflatable telescopic unit 5 is upward, ensuring that the grinding unit 4 moves normally in the vertical direction.

[0054] Specifically, refer to Figure 7 The buckle tooling 11 can be a pair of clamps, which are fixed to the longitudinal rod 2 by bolts to support the support plate 10.

[0055] Alternatively, the buckle fixture 11 is a bolt that penetrates different side walls of the support plate 10, and the end of the bolt abuts against the side wall of the longitudinal rod 2, and the support plate 10 is fixed relative to the longitudinal rod 2 by using friction force.

[0056] In this embodiment, refer to Figure 4 , and also includes: a recovery plate 12, which is fixed on the end surface of the support plate 10 close to the component, and the other end is in contact with the surface of the component; a recovery box 14, which is detachably connected to the bottom end of the support plate 10, and a channel 15 is opened on the recovery box 14, and the recyclables on the recovery plate 12 enter the recovery box 14 through the channel 15.

[0057] Specifically, the recovery plate 12 is fixed on the support plate 10 and is located below the area to be processed. Therefore, during the processing, the concrete residues and waste removed by grinding fall onto the recovery plate 12 and pass through the channel 15 into the recovery box 14 to be collected. This structural setting can avoid subsequent collection and cleaning.

[0058] At the same time, since the recovery plate 12 is fixed on the support plate 10, it can move in the height direction following the support plate 10. Therefore, the recovery plate 12 is close to the area to be processed, and there will be no splashing of residue and waste due to the large height difference between the recovery plate 12 and the area to be processed.

[0059] In addition, the recovery plate 12 can position the base 1 and the slide 3 , and the recovery plate 12 is attached to the surface of the concrete component to determine the initial position of the grinding unit 4 .

[0060] Furthermore, the top surface of the recovery plate 12 is inclined, and the end close to the concrete surface is the high end.

[0061] Further, a plurality of hooks 22 are fixed to the bottom of the support plate 10. The hooks 22 can be used to hang the recycling box 14 or a disposable recycling bag, which is convenient for subsequent treatment of residues and waste.

[0062] In this embodiment, refer to Figure 3 , Figure 6 The inflatable telescopic unit 5 includes: a pair of sliders 501, which are sleeved on the longitudinal rod 2 and slidably matched with the longitudinal rod 2, and the air outlet end of the inflatable telescopic unit 5 is arranged on one of the sliders 501; a telescopic airbag 502, which is sleeved on the longitudinal rod 2 and has its two ends respectively fixed to the two sliders 501, and an air passage cavity is provided in the slider 501 on which the air outlet end of the inflatable telescopic unit 5 is arranged, and the telescopic airbag 502 is connected with the air outlet end of the inflatable telescopic unit 5 through the air passage cavity.

[0063] Specifically, one of the sliders 501 is fixed on the top surface of the support plate 10, and the other slider 501 is fixed on the bottom surface of the slide 3. The telescopic airbag 502 is extended and retracted by inflating and deflating the telescopic airbag 502. At the same time, since the support plate 10 cannot move downward relative to the longitudinal rod 2, during the extension and retraction of the telescopic airbag 502, only the slide 3 and the slider 501 fixed to the slide 3 can move vertically along the longitudinal rod 2.

[0064] In this embodiment, refer to Figure 1 , Figure 3 The inflation unit 6 includes an inflation pump 601 , and the outlet end of the inflation pump 601 is connected to a pair of air supply branch pipes 602 , and the outlet ends of the pair of air supply branch pipes 602 extend into the inflation telescopic unit 5 respectively.

[0065] Specifically, the base 1 should be provided with a battery or a power cord, which is used to power the air pump 601 and the grinder 401 . The air pump 601 supplies air to the two telescopic airbags 502 through the air supply branch pipe 602 .

[0066] The air delivery speed of the air pump 601 needs to be lower than the air outlet speed of the telescopic airbag 502 .

[0067] One end of the gas supply pipe 602 can extend into the gas cavity.

[0068] In this embodiment, refer to Figure 5 A slide groove 16 is provided at the top of the slide 3, and a connecting rod 17 is fixed in the slide groove 16. The extending direction of the connecting rod 17 is the same as the extending direction of the slide 3. A slide plate 18 is sleeved on the connecting rod 17. The slide plate 18 slides in cooperation with the slide groove 16. A moving seat 19 is fixed at the top of the slide plate 18, and the grinding unit 4 is connected to the moving seat 19.

[0069] Specifically, the connecting rod 17 cooperates with the slide plate 18 so that the movable seat 19 can only move along the extension direction of the connecting rod 17, that is, the grinding unit 4 can move along the direction parallel to the surface of the concrete structure. In actual use, the movable seat 19 is manually driven by the operator to move.

[0070] In this embodiment, refer to Figure 5 A pair of guide rails 20 are fixed on the movable seat 19, and the extension direction of the guide rails 20 is perpendicular to the extension direction of the connecting rod 17. The grinding unit 4 includes a grinder 401 and a connecting frame 402 fixed on the grinder 401. The connecting frame 402 is provided with an adaptive guide groove on the end surface close to the guide rails 20, so that the connecting frame 402 and the movable seat 19 are slidably matched and detachably connected.

[0071] Specifically, with the cooperation of the guide rail 20 and the connecting frame 402, the grinding end of the grinder 401 can be close to the surface of the concrete component or away from the surface of the concrete component.

[0072] Furthermore, after the preliminary treatment of the area to be treated is completed, the connecting frame 402 can be separated from the movable base 19, and the operator can use the handheld grinder 401 to further finely grind the area to be treated.

[0073] In this embodiment, refer to Figure 1 , Figure 2 A pulley block 21 is fixed at the bottom of the base 1.

[0074] The existence of the pulley block 21 facilitates the movement of the entire device.

[0075] Specifically, in actual use, the base 1 is moved to a predetermined position, and the position of the support plate 10 on the longitudinal rod 2 is adjusted according to the area to be processed. Then, the grinder 401 and the air pump 601 are turned on, and the grinder 401 is driven up or down according to actual needs. The valve 8 on the air outlet pipe 7 is closed, or the valve 8 on the air outlet pipe 7 is opened to realize the lifting and lowering of the grinder 401, and then the operator can adjust the position of the grinder 401 on the horizontal plane.

[0076] Example 2

[0077] Reference Figure 8 On the basis of Example 1, the difference from Example 1 is that a pair of telescopic hydraulic rods 13 are fixed on the base 1, and the telescopic ends of the telescopic hydraulic rods 13 are fixed to the support plate 10.

[0078] Specifically, under this structural setting, there is no need to set up the snap-fit ​​tool 11, and only the telescopic hydraulic rod 13 needs to be driven to work. It can not only adjust the support plate 10 to further reduce labor intensity, but also directly support the support plate 10, avoiding the installation of the snap-fit ​​tool 11, thereby improving work efficiency.

[0079] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
