Description

Technical Field

[0001] The invention relates to the technical field of shallow circular silo body construction, and in particular to a cleaning device and a cleaning method for concrete stuck on a slip form. Background Art

[0002] During the slipform construction process, concrete needs to be poured continuously. Sometimes concrete will splash onto the slipform platform or some concrete will stick to the top of the slipform. If it is not cleaned in time, the concrete on the slipform operation table will be cleaned into the slipform after it has finally set, which will affect the quality of the concrete. If the concrete on the top of the slipform is not cleaned in time, the net width of the top of the slipform will become smaller and smaller, affecting the installation of the horizontal reinforcement and hooks of the silo wall. Cleaning the concrete on the top of the slipform after it has finally set will directly affect the molding quality of the silo wall concrete.

[0003] The traditional cleaning method is to manually clean the concrete on the slipform operation table with a handheld shovel, or use a special shovel to clean the concrete on the top of the formwork, which has low cleaning efficiency. Summary of the invention

[0004] In view of the above-mentioned defects in the prior art, a cleaning device for concrete sticking on a slipform is provided, which automatically cleans the concrete sticking on the slipform table and the upper mouth of the slipform into the slipform before the concrete initially sets.

When the second scraper is subjected to resistance, it tilts and switches to a horizontal state at the extreme, and the second scraper is always attached to the slipform template.

[0012] According to the above technical scheme, a scraper cleaning shovel structure is also provided on the gate-type bracket, and two groups of scraper cleaning shovel structures are distributed on both sides of the annular gap of the gate-type bracket; the edge line of the contact surface between the scraper blade and the sliding membrane platform is a straight line or a smooth curve, and when the scraper blade located on the sliding membrane platform passes through the scraper cleaning shovel structure, the scraper cleaning shovel structure moves along the edge line toward the annular gap.

[0014] According to the above technical scheme, the driving mechanism includes an annular hanging rail fixed on the gate-type bracket, a pulley trolley slidably connected to the annular hanging rail, a pulley trolley fixedly connected to the annular anti-slip flat steel, a clamping wheel pressed against one side of the annular anti-slip flat steel, a driving wheel pressed against the other side of the annular anti-slip flat steel, and a driving motor connected to the driving wheel; a number of pulley trolleys are arranged at intervals in the annular hanging rail, and the annular anti-slip flat steel is fixed on all the pulley trolleys; the driving motor is fixed on the gate-type bracket, the clamping wheel is rotatably connected to the gate-type bracket, the driving wheel and the clamping wheel are clamped on both sides of the annular anti-slip flat steel, and form a driving unit with the driving motor, and at least one group of driving units is arranged on the driving mechanism.

[0019] During the concrete pouring process, the cleaning device for the concrete stuck on the slipform is always kept in operation.

[0020] The present invention has the following beneficial effects:

[0021] 1. A driving mechanism is arranged on the annular gap, and the moving part of the driving mechanism performs circular motion above the annular gap. A scraper structure is arranged on the moving part, and since the motion trajectory of the moving part on the annular gap is co-centric with the annular gap, the motion trajectory of the scraper structure fixed on the moving part is also co-centric with the annular gap. It can be obtained that if in the initial state, the scraper is attached to the adjacent surfaces of the sliding form platform and the sliding form template located in the annular gap, then in the process of the scraper moving with the moving part, it is always attached to the adjacent surfaces of the sliding form platform and the sliding form template located in the annular gap.

[0022] Therefore, when the scraper moves with the moving part, the sticky concrete on the slipform platform and the slipform template can be scraped off; before the concrete begins to set, the driving mechanism is started to automatically clean the sticky concrete on the slipform template table and the upper edge of the slipform template into the slipform.

[0023] 2. A scraper cleaning shovel structure is also provided on the door-type bracket to prevent concrete from accumulating on the scraper structure and finally setting on the scraper blade. When the scraper cleaning shovel structure moves along the scraper blade, the concrete on the scraper blade is cleaned and scraped and sent to the annular gap, thus ensuring the subsequent scraping operation of the scraper structure.

[0036] Reference Figure 1 to Figure 6 As shown, the cleaning device for concrete stuck on a slipform provided by the present invention.

[0037] Example 1

[0038] The invention is applied to the slipform structure for casting shallow circular silo, and the slipform structure comprises a slipform platform 1, an inner slipform template 2, and an outer slipform template 3. Both the inner and outer slipform templates are cylindrical shell structures. The inner slipform template and the outer slipform template are respectively attached to the inner wall surface and the outer wall surface of the shallow circular silo 4, and an annular gap 5 for casting the silo wall is formed between the two. The slipform platform is arranged at the top of the inner and outer slipform templates, and extends inwardly and outwardly respectively.

[0039] It also includes a gate-type support 6, a driving mechanism 7, and a scraper structure 8. A plurality of gate-type supports are arranged on the slipform platform, the gate-type supports span the annular gap and are spaced along the annular gap; one or more driving mechanisms are arranged on all the gate-type supports, and a moving part is arranged on the driving mechanism. Under the action of the driving mechanism, the moving part moves in a circle inside the gate-type support and above the annular gap, and the movement trajectory of the moving part is co-centered with the annular gap; one or more scraper structures are arranged on one driving mechanism, the top of the scraper structure is fixed on the moving part, and a scraper is arranged at the bottom of the scraper structure, and the scraper is attached to the slipform platform and the slipform template. The scraper scrapes the concrete to the lower part of the annular gap during the movement of the moving part. The gate-type support is composed of a crossbeam 6-1 and a column 6-2.

[0040] In this embodiment, a driving mechanism is arranged on the annular gap, and the moving part of the driving mechanism performs circular motion above the annular gap. A scraper structure is arranged on the moving part, and since the motion trajectory of the moving part on the annular gap is co-centric with the annular gap, the motion trajectory of the scraper structure fixed on the moving part is also co-centric with the annular gap. It can be obtained that if in the initial state, the scraper is attached to the adjacent surfaces of the sliding form platform and the sliding form template located in the annular gap, then in the process of the scraper moving with the moving part, it is always attached to the adjacent surfaces of the sliding form platform and the sliding form template located in the annular gap.

[0041] Therefore, when the scraper moves with the moving part, the sticky concrete on the slipform platform and the slipform template can be scraped off; before the concrete begins to set, the driving mechanism is started to automatically clean the sticky concrete on the slipform template table and the upper edge of the slipform template into the slipform.

[0042] Example 2

[0043] The structure and principle of Example 2 are similar to those of Example 1, except that the scraper blade includes a first scraper blade 8-1 and a second scraper blade 8-2, the first scraper blade is attached to the upper surface of the slipform platform, and one end extends above the annular gap; the second scraper blade is attached to the inner facade of the slipform template and is arranged vertically.

[0044] As shown in the figure, two driving mechanisms are set on all portal brackets, and each driving mechanism is only responsible for scraping the sticky concrete of the slipform platform and slipform template on one side of the annular gap. At this time, the scraper blades in a single set of scraper structures only include a first scraper blade and a second scraper blade.

[0045] There is another situation. If only one driving mechanism is set on all the portal brackets, one driving mechanism is responsible for scraping the sticky concrete of the slipform platform and the slipform formwork on both sides of the annular gap. At this time, the scraper blades in the single set of scraper structure only include two first scraper blades and two second scraper blades; wherein a first scraper blade and a second scraper blade are respectively set on either side of the annular gap.

[0046] In addition, only one set of scraper structures may be provided in the length direction of the driving mechanism, or multiple sets of scraper structures may be provided at intervals along the length direction. Preferably, multiple sets of scraper structures are provided, and the interval between each set of scraper structures is 4m to 5m.

[0047] In Example 2, in order to better scrape the adhering concrete on the slipform platform into the slipform, in the direction of movement along the moving part, the end of the first scraper away from the annular gap is located in front of the end close to the annular gap, and the distances between the two and the center of the annular gap are inconsistent. The first scraper can adopt an arc plate or a straight plate structure. The first scraper has a certain intersection angle with the annular hanging rail. When the pulley trolley drives the first scraper to make a circular motion around the center of the slipform system, the first scraper can scrape the concrete within the width range from the inner side of the door frame column on the slipform platform to the upper mouth of the slipform template into the slipform template.

[0048] In Example 2, in order to avoid damage to the second scraper after the concrete on the slipform is finally set; the second scraper is connected to the scraper structure through a spring hinge, and the axis of the spring hinge is located on the straight line where the radius of the annular gap is located; when the resistance encountered by the second scraper during movement is greater than the spring, the second scraper changes from a vertical state to an inclined state or a horizontal state. When the second scraper does not encounter a small resistance when making a circular motion around the center of the slipform, the second scraper is close to the inside of the slipform and maintains a vertical state; when the second scraper encounters a large resistance when making a circular motion around the center of the slipform, such as encountering a final setting of concrete, the spring in the spring hinge connecting the scraper is squeezed and deformed, and the second scraper changes from a vertical state to a horizontal state, so as to bypass the obstacle; when the scraper encounters concrete that has not been finally set, the scraper scrapes the concrete that sticks to the form into the slipform.

[0049] In Embodiment 2, the sliding form positioning rib 10 is fixed to the sliding form template by means of a thin steel sheet, and the height of the end of the positioning rib is lower than the height of the second scraper blade, so as not to hinder the operation of the second scraper blade.

[0050] Example 3

[0051] The structure and principle of Example 3 are similar to those of Example 2, except that: on the basis of Example 2, a preferred scraper structure is provided, as shown in the figure:

[0052] Two sets of driving mechanisms are arranged on the door-type bracket, and the driving mechanisms are distributed on both sides of the annular gap. A plurality of scraper structures are arranged at intervals in the extension direction on each driving mechanism; the scraper structure includes a hanging plate 8-3, a first scraper, a triangular bracket 8-4, a spring hinge 8-5 and a second scraper. The top of the hanging plate is fixed to the bottom of the moving part, and the first scraper is fixed to the bottom of the hanging plate. In order to strengthen the fixing strength of the first scraper on the hanging plate, a diagonal support rod 8-6 is also fixedly connected between the first scraper and the hanging plate; the triangular bracket is fixed to the end of the first scraper close to the annular gap, and part of the triangular bracket is cantilevered above the annular gap; the second scraper is connected to the triangular bracket through a spring hinge. The second scraper is initially arranged vertically in the annular gap. When the second scraper is subjected to resistance, it tilts and switches to a horizontal state at the limit, and the second scraper is always attached to the sliding formwork.

[0053] Example 4

[0054] The structure and principle of Example 4 are similar to those of Examples 1-3, except that: on the sliding membrane platform, in order to prevent the concrete from accumulating on the scraper structure, and the concrete finally sets on the scraper; a scraper cleaning shovel structure 9 is also provided on the gate-type bracket, and two groups of scraper cleaning shovel structures are distributed on both sides of the annular gap of the gate-type bracket; the edge line of the contact surface between the scraper and the sliding membrane platform is a straight line or a smooth curve, and when the scraper on the sliding membrane platform passes through the scraper cleaning shovel structure, the scraper cleaning shovel structure moves along the edge line toward the annular gap. In the process of the scraper cleaning shovel structure moving along the scraper, the concrete on the scraper is cleaned and scraped, and sent into the annular gap.

[0055] Preferably, a limit stop rod is installed on the crossbeam of the portal bracket using self-tapping screws. The limit stop rod limits the initial position of the scraper cleaning shovel head to the farthest side from the annular gap within the scraper movement trajectory, ensuring that the first scraper blade can contact the scraper cleaning shovel head during movement.

[0056] In Example 4, a preferred scraper cleaning shovel structure is provided; the scraper cleaning shovel structure includes a scraper cleaning shovel 9-1, a hinge 9-2, a sleeve 9-3, a downward pressure spring 9-4, and an external pull spring 9-5; a part of the hinge is fixed on the door-shaped bracket, the sleeve is fixed on the other part of the hinge, and the rotation center line of the sleeve is parallel to the tangent of the annular gap; the scraper cleaning shovel is slidably connected in the sleeve, and under the action of the downward pressure spring, the shovel body of the scraper cleaning shovel is attached to the sliding membrane platform with a certain pressure, and the shovel body is always located within the trajectory of the scraper movement; the external pull spring is connected between the door-shaped column and the scraper cleaning shovel, and under the action of the external pull spring, the shovel body of the scraper cleaning shovel is initially located on the side of the scraper movement trajectory away from the annular gap. The scraper cleaning shovel structure is arranged at intervals along the length direction of the annular slide rail, and the interval range is 4m to 6m.

[0057] In this embodiment, the scraper cleaning shovel is rotatably connected to the door-shaped bracket by a hinge, and the hinge is used to limit the rotation trajectory of the scraper cleaning shovel. Secondly, a sleeve and a downward pressure spring are provided to ensure that the scraper cleaning shovel body is attached to the sliding platform with a certain pressure during the process of the scraper cleaning shovel rotating around the hinge. Finally, the curve of the edge of the contact surface between the scraper blade and the sliding platform is used to give the scraper cleaning shovel body a power to move toward the annular gap along the curve. After the scraper cleaning shovel body moves to the end of the scraper blade located in the annular gap, it slides into the other side of the scraper blade and returns to the initial position under the action of the tension spring.

[0058] When the first scraper blade makes a circular motion around the center of the slipform and encounters the scraper cleaning shovel, the first scraper blade and the scraper cleaning shovel will slide and rub against each other and clean the concrete adhered to the first scraper blade. At the same time, the scraper cleaning shovel is subjected to a lateral pressure greater than the tension of the external pull spring, and the scraper cleaning shovel rotates around the hinge; and rotates out of the space required for the operation of the first scraper blade, without hindering the first scraper blade from making a circular motion around the center of the slipform. When the entire first scraper blade moves in the length direction beyond the range of the scraper cleaning shovel, the scraper cleaning shovel is no longer subjected to the lateral pressure of the first scraper blade, but only to the external tension of the external pull spring, and the scraper cleaning shovel rebounds to the preset position, waiting to clean the next passing scraper. When the next scraper blade moves to the shovel body of the scraper cleaning shovel, the above process is repeated.

[0059] In embodiments 1-4, a preferred structure of the driving mechanism is provided, specifically,

[0060] The driving mechanism includes an annular hanging rail 7-1 fixed on the gate-type bracket, a pulley trolley 7-2 slidably connected to the annular hanging rail, a pulley trolley fixedly connected to an annular anti-slip flat steel 7-3, a clamping wheel 7-4 pressed against one side of the annular anti-slip flat steel, a driving wheel 7-5 pressed against the other side of the annular anti-slip flat steel, and a driving motor 7-6 connected to the driving wheel; a plurality of pulley trolleys are arranged at intervals in the annular hanging rail, and the annular anti-slip flat steel is fixed on all the pulley trolleys; the driving motor is fixed on the gate-type bracket, the clamping wheel is rotatably connected to the gate-type bracket, the driving wheel and the clamping wheel are clamped on both sides of the annular anti-slip flat steel, and form a driving unit with the driving motor, and at least one group of driving units is arranged on the driving mechanism.

[0061] In the embodiment shown in the figure, a drive motor and a drive roller are installed on one side of the hanging card and the steel pressure plate using bolts, and a pressure wheel is installed on the other side of the hanging card and the steel pressure plate; the drive roller is installed on the drive motor, the drive roller is close to one side of the annular flat steel, and the pressure wheel is close to the other side of the corresponding position of the annular flat steel to increase friction, and the drive wheel and the pressure wheel only contact the middle part of the flat steel in the width direction.

[0062] A guide unit consisting only of a clamping wheel may also be provided in the driving mechanism. The guide unit consists of a plurality of clamping wheels and is distributed on both sides of the annular anti-skid flat steel, which is not shown in the figure. In the embodiment in the figure, the annular hanging rail is fixed to the crossbeam of the portal bracket by a steel pressure plate 7-7, a hanging card 7-8, and bolts 7-9. This is a prior art and will not be described in detail here. In addition, the annular anti-skid flat steel is fixed to the hanging plate of the scraper structure by bolts. In the embodiment in the figure, the clamping wheel and the driving motor are installed on the hanging card at intervals through a steel plate 11, and thus installed on the portal bracket at intervals.

[0063] However, the structural form of the driving mechanism is not limited to the above structure. In the prior art, there are many forms of driving mechanisms that can drive the scraper structure to perform circular motion on the door-type bracket. The present invention only adopts a common implementation method to realize the function of the present invention.

[0064] In the above-mentioned preferred driving mechanism, the number of pulley trolleys is evenly distributed in the annular hanging rail at a spacing of no more than 2m (the embodiment in the figure is evenly distributed at a spacing of 1.5m), and the annular anti-slip flat steel is slidably connected to the annular hanging rail through multiple sliding trolleys.

[0065] The present invention also provides a method for cleaning concrete stuck on a slipform, comprising:

[0066] Before pouring concrete into the slipform, a cleaning device for concrete stuck on the slipform as described above is installed on the slipform platform;

[0067] While the concrete is being poured, a cleaning device for the concrete stuck on the slipform is turned on;

[0068] During the concrete pouring process, the cleaning device for the concrete stuck on the slipform is always kept in operation.

[0069] Specifically, after installing the cleaning device for the concrete stuck on the slipform on the slipform platforms on both sides of the annular gap, the concrete pouring begins. While pouring concrete into the slipform, the driving motor of the device is started, and the driving motor drives the annular flat steel to make a circular motion around the center of the slipform, and the annular flat steel drives the first scraper and the second scraper to make a circular motion around the center of the slipform. While the first scraper moves, the concrete splashed within the width range from the inner side of the gate-shaped support column to the upper opening of the slipform template is cleaned into the range of the slipform template; while the second scraper moves in a circular motion, the concrete stuck to the upper opening of the slipform template is cleaned and scraped into the slipform template.

[0070] When the first scraper blade bonded with concrete moves in a circular motion and contacts the scraper cleaning shovel installed on the crossbeam of the portal bracket, the scraper cleaning shovel cleans the concrete on the first scraper blade and pushes it into the slipform. During the concrete pouring process, the cleaning device for the concrete bonded to the slipform is always running, and the concrete is scraped into the slipform range before the initial setting of the concrete bonded to the slipform, so as to prevent the final setting of the concrete bonded to the slipform from affecting the quality of the concrete bonded to the slipform.

[0071] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
