Description

Technical Field

[0001] This utility model relates to the field of building formwork cleaning technology, specifically to a high-efficiency cleaning device for building formwork. Background Technology

[0002] After use, construction formwork (such as steel formwork, wooden formwork, plastic formwork, etc.) often retains dirt such as concrete and mortar. High-efficiency cleaning equipment can significantly improve cleaning efficiency and extend the life of the formwork.

[0003] To improve the cleaning efficiency of building formwork, a composite cleaning method is generally used. Specifically, a scraper is moved on the surface of the building formwork, while a high-pressure nozzle sprays water onto the surface of the building formwork to achieve double cleaning.

[0004] The aforementioned device has a relatively high cleaning efficiency. However, since the traditional scraper moves from one side of the building formwork to the other, the long moving distance not only prolongs the cleaning time and initially reduces the cleaning efficiency of the building formwork, but also generates a large frictional resistance due to the sliding contact of the scraper on the surface of the building formwork. This can easily cause the building formwork to shift or tilt on the workbench. In order to ensure thorough cleaning without dead corners, the staff needs to adjust the placement of the building formwork, which will further reduce the cleaning efficiency of the building formwork. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-efficiency cleaning device for building formwork, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a high-efficiency cleaning device for building templates, including a cleaning table and a plurality of rotating rollers rotatably installed between two opposite inner sidewalls of the cleaning table. Two movable seats slide linearly above the plurality of rotating rollers, either facing each other or moving away from each other. The distance between the two movable seats and the plurality of rotating rollers is adjustable. The bottom of each of the two movable seats is equipped with a scraper with an inclined design. A plurality of nozzles are inclinedly installed on one side of each of the two movable seats.

[0008] A water pump is installed on one side of the cleaning platform. Both output ends of the water pump are connected to flexible hoses. The ends of the two flexible hoses away from the water pump are connected to corresponding movable seats and connected to the input ends of several nozzles.

[0009] Furthermore, the rotating rollers are designed to be parallel to each other at equal intervals and are all exposed on the surface of the cleaning table. The bottom of the cleaning table is vertically fixed with two symmetrically distributed support seats.

[0010] Furthermore, two symmetrically distributed mounting bases are vertically fixed above the cleaning table. A motor is mounted on the outer wall of one of the mounting bases, and a double-ended lead screw is rotatably mounted between the two mounting bases. A coupling is connected between one end of the double-ended lead screw and the output shaft of the motor, and nut seats are threaded onto both ends of the double-ended lead screw.

[0011] Furthermore, a movable rod is vertically fixedly connected to the bottom of each of the two nut seats, and a limiting rod is vertically fixedly connected between the two mounting seats, with the limiting rod passing through both movable rods.

[0012] Furthermore, each of the two movable rods is provided with a connecting rod that is vertically fixed to the top of the movable seat. The top of each of the two connecting rods is threadedly connected to a threaded shaft. The top of each of the two threaded shafts is rotatably mounted to the corresponding movable rod. The outer wall of each of the two threaded shafts is fixedly fitted with a rod sleeve.

[0013] Furthermore, the two opposite outer walls of the two moving rods and the two connecting rods are vertically fixedly connected to fixed plates. The tops of the four fixed plates located below are vertically fixedly installed with limit cylinders. The tops of the four limit cylinders are fitted with limit posts. The tops of the four limit posts are vertically fixedly connected to the fixed plates located above.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] 1. Two symmetrically distributed scrapers are installed above the cleaning platform. By moving the two scrapers toward each other on the surface of the building formwork, the entire stroke that would normally be required by a single scraper is evenly distributed between the two scrapers, thereby initially improving the cleaning efficiency of the building formwork. At the same time, since the two scrapers exert opposite directions of thrust on the building formwork, the building formwork will not tilt or shift without the need for limiting and fixing, thus eliminating the need for staff to adjust the placement of the building formwork and further improving the cleaning efficiency of the building formwork.

[0016] 2. To accommodate building templates of different thicknesses, the distance between the two scrapers and the upper surface of the cleaning table is adjustable, allowing the scrapers to come into contact with building template surfaces of different thicknesses, thus improving the practicality of this cleaning equipment.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example 1:

[0031] Reference Figure 1-4This is the first embodiment of the present invention, which discloses a high-efficiency cleaning device for building templates, including a cleaning table 1 and a plurality of rotating rollers 11 rotatably installed between two opposite inner sidewalls of the cleaning table 1. The two ends of the plurality of rotating rollers 11 are each vertically fixedly connected to a rotating shaft. The two opposite inner sidewalls of the cleaning table 1 are each provided with a rotating hole adapted to the rotating shaft. The plurality of rotating rollers 11 are rotatably connected through the rotating shaft and the rotating hole adapted to each other. They are rotatably set on the cleaning table 1. Two movable seats 4 slide linearly above the plurality of rotating rollers 11, facing each other or moving away from each other. The distance between the two movable seats 4 and the plurality of rotating rollers 11 is adjustable.

[0032] Both movable seats 4 are equipped with inclined scrapers 41 at their bottoms. The two scrapers 41 are symmetrically inclined in a "V" shape. Several nozzles 42 are installed on opposite sides of both movable seats 4. The angle of the nozzles 42 is inclined to ensure that they can spray onto the surface of the building template. The water pump 5 is installed on one side of the cleaning table 1. The input end of the water pump 5 is connected to the inner cavity of an external water tank through a water pipe. A filter screen is installed at the connection between the water pipe and the water tank. Both output ends of the water pump 5 are connected to flexible hoses. The ends of the two flexible hoses away from the water pump 5 are connected to the corresponding movable seats 4 and are connected to the input ends of the nozzles 42.

[0033] Example 2:

[0034] Reference Figure 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the plurality of rotating rollers 11 are designed to be parallel to each other at equal intervals and are all exposed on the surface of the cleaning table 1, so as to ensure that the bottom of the building template placed on the cleaning table 1 first rolls into contact with the plurality of rotating rollers 11. Two symmetrically distributed support seats are vertically fixedly installed on the bottom of the cleaning table 1, and two symmetrically distributed mounting seats 21 are vertically fixedly installed on the top of the cleaning table 1. A motor 22 is installed on the outer side wall of one of the mounting seats 21, and a double-ended lead screw 23 is rotatably installed between the two mounting seats 21. A coupling is connected between one end of the double-ended lead screw 23 and the output shaft of the motor 22. Nut seats 24 are threaded on both ends of the double-ended lead screw 23.

[0035] The bottom of each of the two nut seats 24 is vertically fixedly connected to a moving rod 31. A limit rod 35 is vertically fixedly connected between the two mounting seats 21. The limit rod 35 passes through both moving rods 31. A connecting rod 32 is vertically fixedly connected to the top of the moving seat 4 below each of the two moving rods 31. A threaded shaft 33 is threadedly connected to the top of each of the two connecting rods 32. The top of each of the two threaded shafts 33 is rotatably mounted with the corresponding moving rod 31. A round block with an outer diameter larger than the outer diameter of the threaded shaft 33 is fixedly mounted on the top of the threaded shaft 33. A round cavity is opened at the bottom of the moving rod 31. The round block is rotatably mounted in the round cavity. The top of the threaded shaft 33 extends through into the round cavity and is vertically fixedly connected to the bottom of the round block. The limited rotation of the threaded shaft 33 and the moving rod 31 is realized through the round block and the round cavity. A rod sleeve 34 is fixedly fitted on the outer wall of each of the two threaded shafts 33.

[0036] Two moving rods 31 and two connecting rods 32 are vertically fixed to their two opposite outer walls with fixing plates 36. The tops of the four fixing plates 36 located below are vertically fixed with limiting cylinders 37. The tops of the four limiting cylinders 37 are fitted with limiting posts 38. The tops of the four limiting posts 38 are vertically fixed to the fixing plates 36 located above. The outer wall of the limiting cylinder 37 has an air inlet and outlet hole through the inner cylinder cavity, so that the pressure in the inner cylinder cavity of the limiting cylinder 37 is consistent with the external pressure, avoiding the pressure difference that makes it difficult for the limiting posts 38 to slide up and down in the inner cylinder cavity of the limiting cylinder 37.

[0037] The remaining structure is the same as that in Example 1.

[0038] The workflow of this utility model is as follows:

[0039] First, the formwork to be cleaned (hereinafter referred to as the formwork) is broken up by hammering large pieces of hard concrete to avoid damaging the scraper 41. It is then conveyed to the top of the cleaning table 1 by several rotating rollers 11. At this time, the height of the scraper 41 is adjusted according to the thickness of the formwork. Specifically, the rotating rod sleeve 34 rotates the corresponding threaded shaft 33. Since the top of the threaded shaft 33 is limited to the rotation of the corresponding moving rod 31, and the bottom of the threaded shaft 33 is threaded into the top of the corresponding connecting rod 32, and the connecting rod 32 is restricted by the limiting cylinder 37 and the limiting post 38, it cannot rotate but can only slide up and down. Therefore, the rotation of the threaded shaft 33 will cause the distance between the moving rod 31 and the connecting rod 32 to increase or decrease, while the height of the moving rod 31 itself will not change. In the end, only the height of the scraper 41 installed below the connecting rod 32 will change until the blade of the scraper 41 is in contact with the surface of the formwork. The components used in this cleaning equipment for adjusting the height of the scraper 41 include:

[0040] Next, the motor 22 is started, which drives the double-ended lead screw 23 to rotate through the coupling. The nut seats 24 threaded on both ends of the double-ended lead screw 23 are forced to move towards each other, which ultimately drives the two scrapers 41 to move towards each other and begin to scrape away the concrete debris remaining on the surface of the building formwork. At the same time, the water pump 5 is started. The input end of the water pump 5 is connected to the water tank in advance through a water pipe. The water pump 5 draws water from the water tank and then delivers it to the corresponding nozzles 42 through a hose. The nozzles 42 are moving synchronously with the corresponding scrapers 41 at this time, impacting the front of the scraper 41 in the direction of movement. The water pressure parameter is 1MPa, which is sufficient to wash away the concrete residue and improve the scraping effect of the scraper 41.

[0041] Special note: For building formwork with a significant amount of residual concrete residue on the surface, after the first scraping and spraying cleaning, the left and right positions of the building formwork can be adjusted for a second spraying to improve the scraping and spraying cleaning effect.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
