Description

Technical Field

[0001] The utility model relates to the technical field of control devices for lock chamber bottom plates, in particular to a lock chamber bottom plate surface flatness and protective layer thickness control device. Background Art

[0002] The lock chamber hazard removal and reinforcement project refers to the renovation and reinforcement of sluice gates with safety hazards in order to eliminate safety hazards and ensure the safe operation of water conservancy projects. The lock chamber bottom plate surface flatness and protective layer thickness control device is a device specially used to control the surface flatness of the lock chamber bottom plate concrete and the thickness of the steel bar protective layer. Its main functions include controlling the surface flatness: ensuring that the concrete surface of the lock chamber bottom plate reaches the design flatness and improves the project quality; and controlling the protective layer thickness: accurately controlling the thickness of the steel bar protective layer to prevent steel bar corrosion and improve structural durability.

[0003] According to the announcement number CN220889183U, a device for controlling the surface flatness and protective layer thickness of the bottom plate of a gate chamber includes at least two angle steels, which are arranged in parallel. Two front and rear L-shaped aluminum alloy angle steels are fixed horizontally and vertically on the two parallel angle steels by bolts. The front and rear L-shaped aluminum alloy angle steels extend in the left and right directions respectively. The aluminum alloy angle steel is used to control the flatness of the surface layer when the warehouse is flattened and the angle steel is used to control the thickness of the protective layer when the warehouse is flattened and the attached vibrator is fixed between the front and rear L-shaped aluminum alloy angle steels. The attached vibrator is used to vibrate and raise the slurry of the concrete surface layer and ensure that the angle steel is completely pressed on the steel bar. The device is simple and flexible to operate, can be operated by one person, and has efficient construction. It can effectively control the thickness of the steel bar protective layer while ensuring its flatness.

[0004] However, during the use of the above-mentioned patent, angle steels of different heights are replaced by bolt connections to make the device suitable for structures with different thicknesses of steel bar protective layers. However, this method of fixing the angle steels is relatively cumbersome, requiring staff to use handles to repeatedly turn multiple sets of bolts to cancel the limit on the angle steel for disassembly. After the angle steel is docked with the angle steel frame, the previous bolts need to be turned again to finally complete the replacement of angle steels of different models. The replacement method is time-consuming and labor-intensive, and not convenient enough, which affects the staff's handling of the gate chamber bottom plate. Utility Model Content

The positioning seat 602 extends into it, and a limited position cavity is provided on one side of the top of the No. 1 angle steel 3 close to the positioning seat 602, and the limiting seat 603 extends into it; the side of the spring 606 away from the guide bar 604 is connected to the inner wall of the limiting seat 603, and an elastic telescopic mechanism is formed between the limiting seat 603, the guide bar 604 and the spring 606, and sliding grooves are provided on both sides of the extension plate 601, and the guide bar 604 extends into it, and the outer wall of the slide rod 607 is connected to the extension plate 601 through support blocks; a limited position mechanism 7 is set on both sides of the No. 1 angle steel 3, and the limiting mechanism 7 includes a positioning plate 701, a plug-in plate 702, a limiting bar 703 and a guide bar 604. Toward plate 704, a positioning plate 701 is welded on one side of the outer wall of the second angle steel 4; a plug-in plate 702 is penetrated and connected inside the positioning plate 701, and a limiting strip 703 is penetrated and connected inside the plug-in plate 702, and a guide plate 704 is welded on the top of the limiting strip 703; the limiting strip 703 is distributed in a "mouth"-shaped structure, a storage cavity is provided on the side of the first angle steel 3 close to the second angle steel 4, and the positioning plate 701 extends into it, a fixing cavity is provided inside the positioning plate 701, and the limiting strip 703 extends into it; an installation groove is provided on the top of the leveling plate frame 1, and the extension plate 601 is symmetrically distributed about the vertical center line of the leveling plate frame 1.

[0023] During specific implementation, during the use of the device for controlling the surface flatness and protective layer thickness of the gate chamber bottom plate, when the No. 1 angle steel 3 needs to be replaced due to on-site construction requirements, since the two sides of the bottom end of the leveling plate frame 1 are connected to the extension plate 601, when the extension plate 601 is fitted with the No. 1 angle steel 3, the positioning seat 602 and the limiting seat 603 will be inserted into the No. 1 angle steel 3, thereby limiting the No. 1 angle steel 3 to prevent it from moving horizontally, and then the reset of the spring 606 will generate elastic force, causing the guide strips 604 to move away from each other, and since the guide strips 604 are connected to the fixing pin 605, the guide strips 604 are The movement of the guide bar 604 will drive the fixing pin 605 to move together, and because the top of the guide bar 604 is slidably connected to the slide bar 607, the slide bar 607 is used to limit the movement of the guide bar 604, so that it moves smoothly until the fixing pin 605 is inserted into the positioning seat 602, and then the first angle steel 3 is fixed to prevent it from moving up and down, and subsequently, only the guide bar 604 needs to be moved to disconnect the fixing pin 605 from the positioning seat 602, and then the first angle steel 3 can be disassembled by moving it downward, so that the angle steel can be replaced without repeatedly turning multiple sets of bolts;

[0024] When it is necessary to increase the one-time leveling area of ​​angle steel No. 1 3, since angle steel No. 2 4 is connected to positioning plate 701, angle steel No. 2 4 is first fitted with the outer wall of angle steel No. 1 3. At this time, positioning plate 701 is inserted into angle steel No. 1 3, and then plug-in plate 702 is moved to penetrate positioning plate 701, thereby fixing angle steel No. 2 4. Since limiting strip 703 is connected to guide plate 704, guide plate 704 is moved to make limiting strip 703 penetrate plug-in plate 702. At this time, positioning plate 701, plug-in plate 702 and limiting strip 703 form a cross fixing structure, and then angle steel No. 2 4 is reinforced to prevent it from moving at will, thereby quickly completing the splicing of angle steel No. 2 4 and angle steel No. 1 3, so that the staff can quickly adjust the leveling length of the control device to make it correspond to the specific situation on site, thereby improving work efficiency. When the control device for the surface flatness of the bottom plate of the gate chamber and the thickness of the protective layer is used, it is convenient to replace angle steels and adjust the length of angle steels to improve work efficiency.

[0025] To sum up, when using the device for controlling the surface flatness and protective layer thickness of the gate chamber bottom plate, the worker first holds the handrail 5 with his hand, then starts the vibrator 2 in the leveling plate frame 1 to generate vibration, and then pushes the No. 1 angle steel 3 under the vibrator 2 to move, and then uses the No. 1 angle steel 3 to lift the slurry and scrape the flat layer of concrete, so that the surface flatness of the gate chamber bottom plate and the thickness of the steel bar protective layer are effectively controlled. This is the prior art and will not be elaborated on here. The No. 1 angle steel 3 is fixed by the fixing mechanism 6 to prevent it from moving up and down, and then the angle steel can be replaced without repeatedly turning multiple sets of bolts, saving time and energy. The No. 2 angle steel 4 and the No. 1 angle steel 3 are quickly spliced ​​through the limiting mechanism 7, and then it is convenient for the staff to quickly adjust the leveling length of the control device to make it correspond to the specific situation of the site, thereby improving work efficiency and improving work efficiency.
