[0001] This invention belongs to the field of building construction equipment technology, and in particular relates to an automatic de-icing device for floor formwork and its usage method. Background Technology

[0002] Floor slab construction involves multiple stages, including formwork erection, rebar tying, and concrete pouring. These tasks are substantial and often require carefully planned construction schedules based on available manpower and resources. Typically, rebar tying is done the day after formwork erection. In northern regions, due to low morning temperatures, frost can form on the formwork surface, making it extremely slippery for workers and increasing the risk of falls and injuries, especially near edges and openings. To effectively address these safety risks and reduce hazards on the construction site, frost must be removed from the formwork before workers enter the work area. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides an automatic de-icing device for floor formwork and its usage method, which can efficiently and automatically remove and collect frost from floor formwork, thereby improving the safety of on-site construction.

[0026] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0027] like Figure 1 , Figure 2 As shown, this embodiment of the invention provides an automatic de-icing device for floor formwork 7, including a mobile frame. The mobile frame includes a collection chamber 4, a transmission chamber 3, and a de-icing shovel 1 arranged sequentially along the moving direction; wherein,

[0028] The defrosting scraper 1 is connected to the transfer chamber 3 and is used to scrape the frost that has condensed on the surface of the template 7 and to gather the frost.

[0029] The transfer chamber 3 is provided with a collection port at one end facing the defrost scraper 1. A defrost roller brush 2 is rotatably connected to the collection port. The defrost roller brush 2 can transfer the collected frost to the transfer chamber 3.

[0030] The transfer chamber 3 is connected to the collection chamber 4, and a push-broom assembly 33 is provided inside the transfer chamber 3 to push the frost into the collection chamber 4.

[0031] In the above embodiment, along the moving direction of the mobile frame, the collection box is located at the front end of the mobile frame, the defrost shovel 1 is located at the rear end of the mobile frame, the transmission chamber 3 is located in the middle of the two, and the defrost roller brush 2 is located at the end of the transmission chamber 3 near the defrost shovel 1; wherein, the collection chamber 4 has a collection space that can accommodate frost; the transmission chamber 3 is connected to the collection chamber 4 and communicates with the collection space to form a frost movement channel.

[0032] During the movement of the mobile frame, the defrosting shovel 1 moves synchronously with the mobile frame, scraping away and collecting the frost that has condensed on the surface of the formwork 7. Simultaneously, the rotating defrosting roller 2 transports the collected frost continuously into the transfer chamber 3. Then, the push-sweep component 33 within the transfer chamber 3 pushes the frost in a directional manner, collecting it into the collection chamber 4. This technical solution achieves an integrated structure of scraping and collection, roller transfer, and push-sweep collection. It can automatically remove and collect frost from the floor formwork 7 while the mobile frame is moving continuously, eliminating the need for manual defrosting and avoiding safety hazards such as slipping and falling caused by frost, significantly improving on-site construction safety. The entire defrosting process is completed in one continuous operation as the frame moves. The overall structure is compact, highly automated, and easy to operate and control, improving the efficiency of defrosting the floor formwork 7, and is particularly suitable for the needs of large-area rapid defrosting on construction sites.

[0033] Furthermore, in this embodiment, the bottom of the collection chamber 4 is provided with several heating plates 41. During winter nights in low temperatures, frost easily condenses on the surface of the floor formwork 7. The frost adheres tightly to the formwork 7 surface, and relying solely on the defrosting scraper 1 for physical scraping is insufficient to effectively and thoroughly remove the frost. Therefore, this application adds heating plates 41; before the defrosting scraper 1 performs the scraping operation, the heating plates 41 release heat to preheat and soften the frost, melting it into a semi-molten state. This weakens the adhesion between the frost and the surface of the formwork 7, facilitating the defrosting scraper 1 to quickly scrape, peel, and collect the semi-molten frost, thus improving the thoroughness and efficiency of the defrosting operation.

[0034] Preferably, in this embodiment of the application, a solar panel 42 is provided on the top of the collection chamber 4. The solar panel 42 is connected to a storage battery. The storage battery is electrically connected to the heating plate 41. The solar panel 42 is used to convert light energy into electrical energy and store it in the storage battery. The storage battery can supply power to the heating plate 41. Through the above technical solution, the space on the top of the collection chamber 4 is fully utilized, and energy saving and utilization are achieved.

[0035] Furthermore, in this embodiment, the defrosting scraper 1 includes a scraper plate 11 and a scraper plate 11 driving assembly. The scraper plate 11 is connected to the scraper plate 11 driving assembly, which is connected to the transfer chamber 3 and is used to adjust the height of the scraper plate 11. The contact state between the scraper plate 11 and the surface of the template 7 can be adjusted by the action of the scraper plate 11 driving assembly. For example, when the heating plate 41 is needed to melt the frost, the scraper plate 11 is controlled to move away from the template 7 by the action of the scraper plate 11 driving assembly; when scraping is needed, the scraper plate 11 is controlled to press against the surface of the template 7, forming a tight contact between the scraper plate 11 and the template 7, so as to effectively remove the frost from the surface of the template 7.

[0036] Furthermore, in this embodiment of the application, the scraper 11 includes a frost scraper 111 and a connecting plate 112. One end of the connecting plate 112 is connected to the scraper 11 drive assembly, and the other end is connected to the frost scraper 111. An included angle is provided between the frost scraper 111 and the connecting plate 112 to define a set of frost grooves. The frost-removing plate 111 is used to directly contact the frost, and the connecting plate 112 is used to connect the frost-removing plate 111 and the drive assembly. The drive assembly's movement drives the frost-removing plate 111 to move synchronously, thereby adjusting the distance between the frost-removing plate 111 and the template 7. To ensure its scraping effect, the frost-removing plate 111 should form a certain angle with the surface of the template 7 during operation. This angle can be a right angle, an obtuse angle, or an acute angle. The connecting plate 112 is connected to the opposite end of the frost-removing plate 111 that contacts the frost, and has an angle with the frost-removing plate 111. Thus, the template 7, the frost-removing plate 111, the connecting plate 112, and the conveying chamber enclose and form a frost-accumulating groove to achieve the accumulation of frost. This structure can effectively prevent frost from accumulating to a certain height and then falling over the frost-removing plate 111 and back onto the template 7, affecting the defrosting effect. It also makes it more conducive for the defrosting roller brush 2 to fully contact the frost and transfer the frost into the conveying chamber 3.

[0037] Further, in this embodiment, the defrosting roller brush 2 includes a roller 21, a roller brush drive, and a roller brush bracket 22; the roller brush bracket 22 is connected to the transfer chamber 3; the roller 21 is rotatably connected to the roller brush bracket 22 and to the drive end of the roller 21 drive; the outer periphery of the roller 21 is provided with ratchet teeth 211, including a propelling end placed in the frost accumulation groove and a transfer end embedded in the collection port. Under the action of the roller brush drive, the roller 21 rotates axially, and the frost in the frost accumulation groove of the roller 21 comes into full contact with the defrosting roller brush 2, is propelled and carried by the ratchet teeth 211 on the propelling end, and rotates synchronously with the defrosting roller brush 2; the frost detaches from the ratchet teeth 211 on the transfer end and then enters the collection port; through this setting, the frost in the frost accumulation groove can be continuously transferred to the collection port, realizing the transfer and transportation of frost.

[0038] Furthermore, in this embodiment, the end of the transmission chamber 3 away from the collection port is provided with a conveying port, and a pin 31 is rotatably provided on the top inner side of the conveying port. The collection chamber 4 is provided with a connecting frame connected to the pin 31. The roller 21 also includes a support part, which protrudes from the bottom plate of the transmission chamber 3. Through this setting, the device can operate across different elevation areas, ensuring the effectiveness and thoroughness of the defrosting operation.

[0039] In this embodiment, the bottom of the collection chamber 4 is equipped with rollers 6, and smooth movement is achieved by the rotation of the rollers 6; while the bottom of the transfer chamber 3 is not equipped with rollers 6, but is supported by the support part of the roller 21; at the same time, one end of the connecting frame is fixedly connected to the pin 31, and the other end is fixedly connected to the collection chamber 4. By setting the pin 31, the transfer chamber 3 can rotate relative to the pin 31 under certain conditions, thereby making the transfer chamber 3 and the collection chamber 4 form different connection angles. The purpose is to ensure that the roller 21 can be lowered to the set height between areas with different elevations of the template 7, so as to achieve full contact with the frost and achieve its transfer effect.

[0040] In one specific embodiment, in the area where the beam is located or in the area where the plate is lowered, the elevation of the template 7 is different from the elevation of other locations. When the device travels to an area that crosses different elevations, for example, when the collection bin 4 is located in an area with a higher elevation and the transfer bin 3 is located in an area with a lower elevation, the transfer bin 3 rotates around the pin 31 under its own weight until the roller 21 contacts the surface of the template 7, thus providing support for the transfer bin 3.

[0041] Furthermore, in this embodiment of the application, a flexible seal 32 is provided between the delivery port and the collection chamber 4; the flexible seal 32 is used to seal the gap between the delivery port and the collection chamber 4 to prevent frost from being thrown to the outside from the gap.

[0042] Specifically, the aforementioned flexible seal 32 has deformation recovery characteristics, forming a flexible sealing connection between the transmission chamber 3 and the collection chamber 4. With the cooperation of the pin 31, the transmission chamber 3 is allowed to rotate around the pin 31 and deform synchronously to maintain the sealing of the frost transmission channel.

[0043] In one specific embodiment, the flexible seal 32 is made of rubber. One end of it is fixed to the side end face of the conveying port or the outside of the chamber of the transmission chamber 3 by fasteners, and the other end is fixed to the side end face or the outside of the chamber of the collection chamber 4 by fasteners. It can be set in a whole circle along the circumference of both, or set at a certain height at the bottom of the corresponding chamber bottom plate and wall plate.

[0044] Further, in this embodiment, the sweeping assembly 33 includes a rotary drive 331, a rotary shaft 332, a scraper 333, and a cleaning brush 334; the rotary shaft 332 is connected to the rotary drive 331 and rotates axially under the action of the rotary drive 331; the scraper 333 is evenly arranged circumferentially at one end of the rotary shaft 332, and the cleaning brush 334 is arranged at the bottom of the scraper 333 and at the end away from the rotary shaft 332, and abuts against the bottom plate of the transfer chamber 3. The length of the scraper 333 allows the end away from the rotary shaft 332 to extend to the collection port and the delivery port. As the rotary shaft 332 rotates, the scraper 333 drives the cleaning brush 334 to push the frost on the bottom plate to the delivery port, and then into the collection chamber 4.

[0045] Preferably, the cleaning brush 334 located at the end of the scraper 333 has sufficient length to fully contact the defrosting roller brush 2 and sweep the frost it carries into the transfer chamber 3.

[0046] In one specific embodiment, the transfer chamber 3 is provided with a horizontal partition, which divides the transfer chamber 3 into an upper installation chamber and a lower transfer chamber. The flipping shaft 12 and flipping drive, the pin shaft 31 and the rotation drive 331 are all arranged in the installation chamber. The rotation shaft 332 extends through the horizontal partition to the top of the bottom plate of the transfer chamber 3. The scraper 333 has a set height, which is greater than the height of frost accumulation on the bottom plate under normal circumstances. The cleaning brush 334 is arranged at the bottom of the scraper 333 and is in close contact with the bottom plate of the transfer chamber 3 to achieve a good sweeping effect. With the cooperation of the scraper 333 and the defrosting roller brush 2, the continuous transfer of frost is realized.

[0047] This application embodiment also proposes a method for using the above-mentioned automatic de-icing device for floor formwork 7, including the following steps:

[0048] S1. Adjust the height of the defrosting spatula 1 according to the thickness of the frost layer 8 so that it does not come into contact with the frost;

[0049] S2. Control the movement of the mobile frame and turn on the heating plate 41;

[0050] The temperature of the heating plate 41 is set according to the thickness of the frost. Before moving, the heating plate 41 is turned on to preheat for 2-3 minutes. The moving speed of the moving frame is adjusted according to the thickness of the frost and the melting situation. For areas with thicker frost or harder freezing, the frost can be softened by heating multiple times to ensure that the frost layer 8 is wet and soft but does not melt into water.

[0051] S3. After the frost layer 8 is loosened, adjust the height of the defrosting scraper 1 until it contacts the surface of the template 7.

[0052] When the device is moved to templates 7 at different elevations, the height of the defrosting shovel 1 needs to be adjusted accordingly to ensure that it can contact the surface of template 7.

[0053] S4. Control the movement of the mobile frame and activate the defrosting roller brush 2 and the push sweeping assembly 33.

[0054] Ensure that the defrosting roller brush 2 fully contacts the frost surface. As the mobile frame moves, the accumulated frost and snow are continuously moved and transferred to the transfer chamber 3, and then pushed and swept into the collection chamber 4 by the scraper 333 of the push-sweep assembly 33, thus completing the removal and collection of frost.

[0055] In one specific embodiment, the above-mentioned automatic de-icing device for floor formwork 7 is 1.8 meters long and 1.2 meters wide. The bottom of the collection chamber 4 is evenly equipped with four sets of rollers 6, which can adapt to the beam spacing of most construction sites, ensuring that the whole device can move stably and is not easy to fall into the groove of the formwork 7 formed at the beam location.

[0056] The advantages and positive effects of this invention are as follows: This application uses a defrosting shovel to remove and collect frost from the surface of the formwork; simultaneously, a rotating defrosting roller brush transports the collected frost continuously into the transmission chamber; then, a push-sweep component inside the transmission chamber pushes the frost in a directional manner, causing it to be collected in the collection chamber. This achieves an integrated structure of shoveling and collection, roller brush transportation, and push-sweep collection, which can simultaneously complete the automatic removal and centralized collection of frost from the floor formwork during the continuous movement of the mobile frame, eliminating the need for manual defrosting and avoiding safety hazards such as slipping and falling caused by frost, thus significantly improving on-site construction safety; the defrosting operation is completed in one continuous linkage with the movement of the frame, and the overall structure is compact, highly automated, simple to operate, and easy to control, improving the efficiency of floor formwork defrosting operations, especially suitable for the needs of large-area rapid defrosting on construction sites.

[0057] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
