If not cleaned in time, the concrete on the slipform operating platform will be hardened, and cleaning the concrete in the slipform formwork will affect the quality of the concrete. If the concrete on the upper part of the slipform formwork is not cleaned in time, the net width of the upper part of the slipform formwork will become smaller and smaller, affecting the installation of the horizontal reinforcement and the draw hook of the silo wall. Cleaning the concrete on the upper part of the slipform after it is hardened will directly affect the forming quality of the concrete of the silo wall.

[0036] Reference Figures 1-6 As shown, the present invention provides a cleaning device for concrete stuck on a slip form.

[0037] Example 1

[0038] The application is applied to the slip-form structure of pouring shallow silos, and the slip-form structure comprises a slip-form platform 1 and inner and outer slip-form templates 2 and 3. The inner and outer slip-form templates are in the form of cylindrical shell structures, and are attached to the inner and outer wall surfaces of the shallow silo 4 respectively, and form an annular gap 5 between them for pouring the wall of the shallow silo. The slip-form platform is arranged at the top end of the inner and outer slip-form templates and extends inward and outward respectively.

[0039] The application further comprises door-shaped supports 6, a driving mechanism 7 and a scraper structure 8. A plurality of door-shaped supports are arranged on the slip-form platform, and the door-shaped supports are arranged across the annular gap and are spaced along the annular gap. One or more driving mechanisms are arranged on all the door-shaped supports, and a moving part is arranged on the driving mechanism. The moving part makes circular motion in the door-shaped support and above the annular gap under the action of the driving mechanism, and the movement track of the moving part has the same center as the annular gap. One or more groups of scraper structures are arranged on the driving mechanism, the top of the scraper structure is fixed on the moving part, and the bottom of the scraper structure is provided with a scraper blade which is attached to the slip-form platform and the slip-form template. The scraper blade moves with the moving part and sends the concrete to the lower part of the annular gap. The door-shaped support is composed of a cross beam 6-1 and a vertical column 6-2.

[0040] In the embodiment, the driving mechanism is arranged on the annular gap, and the moving part of the driving mechanism makes circular motion above the annular gap. The scraper structure is arranged on the moving part. Since the movement track of the moving part has the same center as the annular gap, the movement track of the scraper structure fixed on the moving part also has the same center as the annular gap. Therefore, if the scraper blade is attached to the adjacent surfaces of the slip-form platform and the slip-form template in the initial state, the scraper blade is always attached to the adjacent surfaces of the slip-form platform and the slip-form template in the process of moving with the moving part.

[0041] Therefore, in the process of moving with the moving part, the adhered concrete on the slip-form platform and the slip-form template can be scraped off, and the driving mechanism is started to automatically clean the adhered concrete on the top surface of the slip-form template and the slip-form template to the inside of the slip-form before the initial setting of the concrete.

[0042] Embodiment 2

[0043] The structure and principle of the embodiment 2 are similar to those of the embodiment 1, and the difference lies in that the scraper blade comprises 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 slip-form platform and extends to above the annular gap at one end. The second scraper blade is attached to the inner vertical surface of the slip-form template and is arranged vertically.

[0044] As shown in the figure, two driving mechanisms are arranged on all portal frames, and each driving mechanism is only responsible for the scraping operation of the adhered concrete of the sliding formwork and sliding platform on one side of the annular gap. At this time, the scraping blades in the single set of scraping plate structure only include one first scraping blade and one second scraping blade.

[0045] There is another case, if only one driving mechanism is arranged on all portal frames, and the driving mechanism is responsible for the scraping operation of the adhered concrete of the sliding formwork and sliding platform on both sides of the annular gap. At this time, the scraping blades in the single set of scraping plate structure only include two first scraping blades and two second scraping blades; one first scraping blade and one second scraping blade are arranged on any side of the annular gap respectively.

[0046] In addition, in the length direction of the driving mechanism, only one set of scraping plate structure can be arranged, or multiple sets of scraping plate structures can be arranged at intervals along the length direction. Preferably, multiple sets of scraping plate structures are arranged, and the interval of each set of scraping plate structure is 4m~5m.

[0047] In embodiment 2, in order to better scrape the adhered concrete on the sliding platform into the sliding formwork, in the direction of the movement of the moving part, the end of the first scraping blade away from the annular gap is located on the front side close to the end of the annular gap, and the distance of the two from the center of the annular gap is inconsistent. The first scraping blade can adopt an arc plate or a straight plate structure. The first scraping blade has a certain intersection angle with the annular suspension rail. When the pulley trolley drives the first scraping blade to make a circular motion around the center of the sliding form system, the first scraping blade can scrape the concrete in the width range from the inner side of the column of the portal frame on the sliding platform to the upper opening of the sliding formwork into the sliding formwork.

[0048] In embodiment 2, in order to avoid damage to the second scraping blade after the concrete on the sliding formwork is finally cured, the second scraping blade is connected to the scraping plate structure through a spring hinge, the axis of the spring hinge is located on the straight line where the radius of the annular gap is located; the resistance received by the second scraping blade during movement is greater than the spring, and the second scraping blade changes from a vertical state to an inclined state or a horizontal state. When the second scraping blade makes a circular motion around the center of the sliding form and does not encounter a small resistance, the second scraping blade keeps a vertical state close to the inner side of the sliding formwork; when the second scraping blade makes a circular motion around the center of the sliding form and encounters a large resistance, for example, encounters the finally cured concrete, the spring in the spring hinge connecting the scraping blade is extruded to deform, and the second scraping blade changes from a vertical state to a horizontal state, so as to bypass the obstacle; when the scraping blade encounters the concrete that has not been finally cured, the scraping blade scrapes the adhered concrete into the sliding formwork.

[0049] In embodiment 2, the sliding form positioning rib 10 is fixed on the sliding formwork through a thin steel sheet, and the height of the end of the positioning rib is lower than the height of the second scraping blade, which does not hinder the operation of the second scraping blade.

[0050] Embodiment 3

[0051] The structure and principle of embodiment 3 are similar to those of embodiment 2, with the difference that a preferred structure of the scraper structure is given on the basis of embodiment 2, as shown in detail in the figure:

[0052] Two groups of driving mechanisms are arranged on the door-shaped support, the driving mechanisms are distributed on the two sides of the annular gap, and a plurality of scraper structures are arranged on each driving mechanism in the length direction; the scraper structure comprises a hanging plate 8-3, a first scraper, a triangular support 8-4, a spring hinge 8-5, and a second scraper, the top end of the hanging plate is fixed to the bottom of the moving part, the first scraper is fixed to the bottom of the hanging plate, and in order to strengthen the fixing strength of the first scraper on the hanging plate, a diagonal support rod 8-6 is further fixedly connected between the first scraper and the hanging plate; the triangular support is fixed to the end of the first scraper close to the annular gap, and part of the triangular support overhangs above the annular gap; the second scraper is connected to the triangular support through the spring hinge, the second scraper is vertically arranged in the annular gap in the initial state, and when the second scraper is subjected to resistance, it is inclined, and is switched to a horizontal state in the limit, and the second scraper is always attached to the slip formwork.

[0053] Embodiment 4

[0054] The structure and principle of embodiment 4 are similar to those of embodiments 1-3, with the difference that on the slip form platform, in order to avoid the accumulation of concrete on the scraper structure, and the final setting of the concrete on the scraper; the door-shaped support is also provided with a scraper cleaning shovel structure 9, and two groups of scraper cleaning shovel structures are distributed on the two sides of the annular gap of the door-shaped support; the edge line of the contact surface of the scraper and the slip form platform is a straight line or a smooth curve, when the scraper on the slip form platform passes through the scraper cleaning shovel structure, the scraper cleaning shovel structure moves along the edge line towards the annular gap. In the process of moving of the scraper cleaning shovel structure along the scraper, the concrete on the scraper is cleaned and scraped off and scraped into the annular gap.

[0055] Preferably, a limiting stop rod is installed on the cross beam of the door-shaped support using a self-tapping screw, the limiting stop rod limits the initial position of the head of the scraper cleaning shovel within the range of the movement track of the scraper, away from the farthest side of the annular gap, and ensures that the first scraper can be in contact with the head of the scraper cleaning shovel during movement.

[0056] In embodiment 4, a preferred structure of the scraper cleaning shovel is given; the scraper cleaning shovel structure includes a scraper cleaning shovel 9-1, a hinge 9-2, a sleeve 9-3, a pressing spring 9-4, and an outer pulling spring 9-5; a part of the hinge is fixed on the door-shaped support, the sleeve is fixed on another part of the hinge, and the rotation center line of the sleeve is parallel to the tangent line of the annular gap; the scraper cleaning shovel is slidingly connected in the sleeve, and under the action of the pressing spring, the shovel body of the scraper cleaning shovel is attached to the sliding platform with a certain pressure, and the shovel body is always located within the track range of the scraper blade movement; the outer pulling spring is connected between the door-shaped column and the scraper cleaning shovel, and under the action of the outer pulling spring, the shovel body of the scraper cleaning shovel is initially located on the side of the scraper movement track away from the annular gap. The scraper cleaning shovel structure is arranged at intervals along the length direction of the annular sliding rail, and the interval range is 4m-6m.

[0057] In the embodiment, the scraper cleaning shovel is rotationally connected to the door-shaped support by the hinge, and the rotation track of the scraper cleaning shovel is limited by the hinge. Secondly, the sleeve and the pressing spring are arranged to ensure that the shovel body of the scraper cleaning shovel is attached to the sliding platform with a certain pressure during the rotation of the scraper cleaning shovel around the hinge. Finally, the curve at the edge of the contact surface between the scraper blade and the sliding platform is used to give the shovel body of the scraper cleaning shovel a power to move along the curve towards the annular gap, and after the shovel body of the scraper cleaning shovel moves to the end of the scraper blade located in the annular gap, the shovel body slides to the other side of the scraper blade and returns to the initial position under the action of the pulling spring.

[0058] When the first scraper blade moves around the sliding center and meets the scraper cleaning shovel, the first scraper blade and the scraper cleaning shovel slide and clean the concrete adhered to the first scraper blade. At the same time, the scraper cleaning shovel is rotated around the hinge under the side pressure greater than the pulling force of the outer pulling spring, and the scraper cleaning shovel rotates out of the space range required for the movement of the first scraper blade, without hindering the movement of the first scraper blade around the sliding center. When the length direction of the entire first scraper blade moves beyond the range of the scraper cleaning shovel, the scraper cleaning shovel is no longer subjected to the side pressure of the first scraper blade, but only to the pulling force of the outer pulling spring, and the scraper cleaning shovel returns to the preset position and waits for the next passing scraper blade. 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 given, specifically,

[0060] The driving mechanism comprises a ring-shaped hanging rail 7-1 fixed on the door-shaped support, a pulley trolley 7-2 slidingly connected on the ring-shaped hanging rail, a ring-shaped anti-skid flat steel 7-3 fixedly connected with the pulley trolley, a pressing wheel 7-4 closely attached to one side of the ring-shaped anti-skid flat steel, a driving wheel 7-5 closely attached to the other side of the ring-shaped anti-skid flat steel, and a driving motor 7-6 connected with the driving wheel; a plurality of pulley trolleys are arranged at intervals in the ring-shaped hanging rail, and the ring-shaped anti-skid flat steel is fixed on all the pulley trolleys; the driving motor is fixed on the door-shaped support, and the pressing wheel is rotatably connected on the door-shaped support; the driving wheel and the pressing wheel are clamped on the two sides of the ring-shaped anti-skid flat steel and form a driving unit with the driving motor; and at least one set of driving units is arranged on the driving mechanism.

[0061] In the embodiment shown in the figure, the driving motor and the driving roller are installed on one side of the lifting clamp and the steel pressing plate by using bolts, and the pressure wheel is installed on the other side of the lifting clamp and the steel pressing plate; the driving roller is installed on the driving motor, the driving roller is closely attached to one side of the ring-shaped flat steel, the pressure wheel is closely attached to the other side of the corresponding position of the ring-shaped flat steel, the friction force is increased, and the driving wheel and the pressure wheel only contact the middle part in the width direction of the flat steel.

[0062] A guide unit composed of only the pressing wheels can also be arranged in the driving mechanism, and the guide unit is composed of a plurality of pressing wheels and is distributed on the two sides of the ring-shaped anti-skid flat steel, which is not shown in the figure. In the embodiment shown in the figure, the ring-shaped hanging rail is fixed on the cross beam of the door-shaped support through the steel pressing plate 7-7, the lifting clamp 7-8, and the bolts 7-9, which is a prior art and will not be described here. In addition, the ring-shaped anti-skid flat steel is fixed on the lifting plate of the scraper structure by bolts. In the embodiment shown in the figure, the pressing wheel and the driving motor are arranged at intervals on the lifting clamp through the steel plate 11, so as to be arranged at intervals on the door-shaped support.

[0063] However, the structure of the driving mechanism is not limited to the above structure, and in the prior art, there are many forms of driving mechanisms that can drive the scraper structure to make a circular motion on the door-shaped support. The present application only uses a common implementation as a function to realize the present application.

[0064] In the preferred driving mechanism described above, the number of pulley trolleys is evenly distributed at intervals not greater than 2m in the ring-shaped hanging rail (the embodiment shown in the figure is evenly distributed at intervals of 1.5m), and the ring-shaped anti-skid flat steel is slidingly connected on the ring-shaped hanging rail through a plurality of pulley trolleys.

[0065] The present application also provides a method for cleaning the concrete adhered to the formwork on the slip form, comprising

[0066] Before pouring the concrete into the slip form, the cleaning device for cleaning the concrete adhered to the formwork on the slip form as described above is installed on the slip form platform;

[0069] Specifically, after the device for cleaning the concrete adhered to the slipform is installed on the inner and outer sides of the slipform platform, the concrete is poured. At the same time of pouring the concrete into the slipform, the driving motor of the device is started to drive the annular flat steel to move around the center of the slipform, and the annular flat steel drives the first scraper and the second scraper to move around the center of the slipform. The first scraper moves to clean the concrete splashed in the range from the inside of the door-shaped support column to the top of the slipform formwork to the slipform formwork; and the second scraper moves to clean the concrete adhered to the top of the slipform formwork to the slipform formwork.

[0070] When the first scraper with the adhered concrete moves around and contacts the scraping shovel installed on the beam of the door-shaped support, the scraping shovel cleans the concrete on the first scraper and pushes it into the slipform formwork. In the process of pouring concrete, the device for cleaning the concrete adhered to the slipform is always in operation, and the concrete is cleaned to the slipform formwork before the initial setting of the adhered concrete, so as to prevent the final setting of the adhered concrete from affecting the quality of the concrete in the slipform.
