Description

Technical Field

[0001] This utility model relates to the field of stair support pad positioning technology, and in particular to a high-precision positioning frame for sliding stair support pads. Background Technology

[0002] Sliding stair support pads are a key component used in steel structure staircases or cast-in-place staircases. They are mainly used to form a sliding contact surface at the staircase support to allow the staircase to slide freely under earthquakes or other external forces, thereby reducing the impact on the main structure. If the pad is not installed in an accurate position, it may cause uneven sliding or even jamming, preventing the staircase from playing its proper seismic resistance role. Therefore, a high-precision positioning frame for sliding stair support pads is required.

[0003] A search revealed Chinese Patent Publication No. CN214615524U, which discloses a special device for installing and positioning sliding supports for stairs. The device includes a main body for positioning the sliding support at the landing platform of a staircase. The main body includes a positioning mounting plate with several horizontal bars at its bottom. Multiple supporting positioning devices are fixedly connected at equal or unequal intervals at the bottom of the horizontal bars. This invention provides a convenient, simple, and reliable installation and positioning device for sliding supports of stairs. It ensures the installation quality of the sliding support plate at the landing platform, better utilizes the function of the sliding support, and improves work efficiency while effectively enhancing the installation quality of the sliding support at the landing platform. This reduces the stress on the stair slab, avoids the formation of stair slab supports and weakens rigidity, and releases the destructive force of ground motion without causing structural deformation or even damage when subjected to seismic forces.

[0004] In the aforementioned utility model, several crossbars are provided at the bottom of the mounting plate, and multiple support positioning devices are fixedly connected at the bottom of the crossbars to ensure the installation quality of the sliding support plate at the rest platform position. However, in actual use, there is still a problem that when installing the support, no fine-tuning device is involved, making it impossible to fine-tune the position of the positioning frame, resulting in low accuracy of the support pad installation. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-precision positioning frame for sliding stair support pads, aiming to improve the problem of the inability to fine-tune the position of the positioning frame and the low accuracy of the support pad installation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision positioning frame for a sliding stair support pad, comprising a base plate, a scale plate fixedly connected to the upper surface of the base plate, a positioning frame body slidably connected to the outer wall of the scale plate, a positioning block fixedly connected to the outer wall of the positioning frame body, a sliding column slidably connected inside the positioning block, a positioning plate fixedly connected to the outer wall of the sliding column, the outer wall of the positioning plate slidably connected to the inside of the scale plate, a spring one provided on the outer wall of the sliding column, one end of the spring one fixedly connected to the inside of the positioning block, the other end of the spring one fixedly connected to the outer wall of the positioning plate, a locking pin slidably connected inside the sliding column, a sliding piece fixedly connected to the outer wall of the locking pin, the outer wall of the sliding piece slidably connected to the inside of the positioning block, a second spring provided on the upper surface of the sliding piece, the outer wall of the second spring fixedly connected to the inside of the positioning block, and a fixing component provided on the upper surface of the base plate.

[0007] Through the above technical solution: The base plate supports the positioning frame. The scale plate allows for precise control of the positioning frame's movement, while the positioning block provides positioning. The sliding column inside the positioning block causes the positioning plate to slide inside the scale plate, engaging the scale plate and thus limiting the positioning frame's position. The locking pin engages the sliding column, and springs one and two provide rebound. Pulling the locking pin in conjunction with the sliding piece allows the positioning plate to automatically spring into the scale plate, achieving automatic positioning of the positioning frame.

[0008] As a further description of the above technical solution: The fixing component includes a limiting strip, the lower surface of which is fixedly connected to the upper surface of the base plate.

Fixing plates are provided on both sides of the positioning frame body. After the fixing plates are tightly fitted to the positioning frame body, they are fixed to the base plate with bolts. The base plate has multiple threaded holes inside for connecting bolts.

[0010] As a further description of the above technical solution: An electric telescopic rod is fixedly connected inside the positioning frame body, and a connecting plate is fixedly connected to the output end of the electric telescopic rod. The outer wall of the connecting plate is slidably connected to the inside of the positioning frame body.

[0011] Through the above technical solution: The positioning frame body serves to fix the electric telescopic rod, which in turn drives the connecting plate to slide. The connecting plate slides stably inside the positioning frame body.

[0012] As a further description of the above technical solution: A sliding plate is fixedly connected to the outer wall of the connecting plate, and the outer wall of the sliding plate is slidably connected to the inside of the positioning frame body.

[0013] Through the above technical solution: The sliding plate can be driven to slide by the sliding of the connecting plate. The sliding plate has a groove inside, which can drive the sliding shaft to slide when the sliding plate slides.

[0014] As a further description of the above technical solution: A bracket is fixedly connected to the upper surface of the positioning frame body, and a rotating shaft is fixedly connected inside the bracket.

[0015] Through the above technical solution: The positioning frame body fixes the bracket, and the bracket supports the rotating shaft.

[0016] As a further description of the above technical solution: A clamping plate is rotatably connected to the outer wall of the rotating shaft, and a pressure roller is provided inside the clamping plate.

[0017] Through the above technical solution: The clamping plate rotates on the outer wall of the rotating shaft, and the rotating shaft supports the clamping plate. The rotation of the clamping plate can drive the pressure roller to clamp and fix the pad.

[0018] As a further description of the above technical solution: The clamping plate is fixedly connected to a connecting shaft inside, and a connecting column is rotatably connected to the outer wall of the connecting shaft.

[0019] Through the above technical solution: The clamping plate fixes the connecting shaft in place. When the connecting column moves, it can drive the connecting shaft to move, and the connecting shaft can drive the clamping plate to rotate.

[0020] As a further description of the above technical solution: A sliding block is fixedly connected to the outer wall of the connecting column. The outer wall of the sliding block is slidably connected to the inside of the positioning frame body. A sliding shaft is fixedly connected inside the sliding block.

[0021] Through the above technical solution: When the sliding plate moves, the sliding groove inside the sliding plate can drive the sliding shaft to slide, and the sliding shaft can drive the sliding block to slide inside the positioning frame body. The sliding block can drive the connecting column to move.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a high-precision positioning frame for a sliding stair support pad, comprising a base plate 1, a scale plate 2 fixedly connected to the upper surface of the base plate 1, a positioning frame body 3 slidably connected to the outer wall of the scale plate 2, a positioning block 4 fixedly connected to the outer wall of the positioning frame body 3, a sliding column 5 slidably connected to the inside of the positioning block 4, a positioning plate 7 fixedly connected to the outer wall of the sliding column 5, the outer wall of the positioning plate 7 slidably connected to the inside of the scale plate 2, a spring 6 provided on the outer wall of the sliding column 5, one end of the spring 6 fixedly connected to the inside of the positioning block 4, the other end of the spring 6 fixedly connected to the outer wall of the positioning plate 7, a locking column 8 slidably connected to the inside of the sliding column 5, a sliding piece 9 fixedly connected to the outer wall of the locking column 8, the outer wall of the sliding piece 9 slidably connected to the inside of the positioning block 4, a second spring 10 provided on the upper surface of the sliding piece 9, the outer wall of the second spring 10 fixedly connected to the inside of the positioning block 4, and a fixing component 11 provided on the upper surface of the base plate 1; Specifically, the base plate 1 fixes the scale plate 2. The upper surface of the scale plate 2 is marked with graduations, which can accurately position the positioning frame body 3. The positioning frame body 3 slides on the outer wall of the scale plate 2. The outer wall of the positioning frame body 3 is equipped with a handle for assisting in pulling the positioning frame body 3. The positioning frame body 3 fixes the positioning block 4, which is used for auxiliary positioning. The locking post 8 can drive the sliding piece 9 to slide. The sliding piece 9 can drive the second spring 10 to be compressed. The second spring 10 can rebound and drive the locking post 8 to engage with the sliding post 5. By pulling the locking post 8 out of the sliding post 5, the first spring 6 can rebound and drive the positioning plate 7 to slide inside the positioning block 4. The positioning plate 7 slides into the scale plate 2 and engages with the scale plate 2, thus limiting the position of the positioning frame body 3. This achieves the effect of fixing the position of the positioning frame body 3 after fine adjustment, thereby improving the adaptability of the device.

[0028] Reference Figure 2The fixing component 11 includes a limiting strip 1101. The lower surface of the limiting strip 1101 is fixedly connected to the upper surface of the base plate 1.

A bolt 1103 is provided inside the fixing plate 1102. The outer wall of the bolt 1103 is threadedly connected to the inside of the base plate 1. Specifically, the base plate 1 fixes the limiting strip 1101, and the limiting strip 1101 limits the positioning frame body 3, ensuring that the positioning frame body 3 always moves in a straight line. Fixing plates 1102 are respectively provided on both sides of the positioning frame body 3, which drive the two fixing plates 1102 to fit tightly with the positioning frame body 3. Then, the fixing plates 1102 and the base plate 1 are fixed by bolts 1103, thereby achieving the effect of reinforcing the positioning frame body 3 and preventing the positioning frame body 3 from shifting.

[0029] Reference Figure 4 An electric telescopic rod 12 is fixedly connected inside the positioning frame body 3. A connecting plate 13 is fixedly connected to the output end of the electric telescopic rod 12. The outer wall of the connecting plate 13 is slidably connected to the inside of the positioning frame body 3. A sliding plate 14 is fixedly connected to the outer wall of the connecting plate 13. The outer wall of the sliding plate 14 is slidably connected to the inside of the positioning frame body 3. Specifically, the positioning frame body 3 plays a role in fixing the electric telescopic rod 12. By activating the electric telescopic rod 12, the connecting plate 13 can be driven to slide inside the positioning frame body 3. The connecting plate 13 can drive the sliding plate 14 to slide inside the positioning frame body 3. The positioning frame body 3 has a sliding groove inside to limit the connection plate 13, which can ensure that the connection plate 13 slides stably.

[0030] Reference Figure 4 and Figure 5 A bracket 15 is fixedly connected to the upper surface of the positioning frame body 3, and a rotating shaft 16 is fixedly connected inside the bracket 15. A clamping plate 17 is rotatably connected to the outer wall of the rotating shaft 16, and a pressure roller 18 is provided inside the clamping plate 17. A connecting shaft 19 is fixedly connected inside the clamping plate 17, and a connecting column 20 is rotatably connected to the outer wall of the connecting shaft 19. A sliding block 21 is fixedly connected to the outer wall of the connecting column 20, and the outer wall of the sliding block 21 is slidably connected inside the positioning frame body 3. A sliding shaft 22 is fixedly connected inside the sliding block 21, and the outer wall of the sliding shaft 22 is slidably connected inside the sliding plate 14. Specifically, the positioning frame body 3 fixes the bracket 15, the bracket 15 fixes the rotating shaft 16, and the rotating shaft 16 supports the clamping plate 17. The rotation of the clamping plate 17 on the outer wall of the rotating shaft 16 can drive the pressure roller 18 to press and fix the pad. The sliding plate 14 can slide the sliding shaft 22 inside the sliding plate 14. The sliding shaft 22 can drive the sliding block 21 to slide inside the positioning frame body 3. The sliding block 21 can drive the connecting column 20 to move. The rotation of the connecting column 20 on the outer wall of the connecting shaft 19 can drive the connecting shaft 19 to move. The connecting shaft 19 can drive the clamping plate 17 to rotate, thus achieving the effect of clamping and fixing the pad.

[0031] Working principle: When the positioning frame is needed, first fix the stair support pad on the positioning frame, place the pad on the upper surface of the positioning frame body 3, and start the electric telescopic rod 12 to drive the connecting plate 13 to slide inside the positioning frame body 3, thereby driving the sliding plate 14 to slide. While the sliding plate 14 is sliding, the sliding shaft 22 can slide on the sliding groove opened inside the sliding plate 14, thereby driving the sliding block 21 to slide inside the positioning frame body 3. The sliding block 21 can drive the connecting column 20 to move, thereby driving the connecting column 20 to rotate on the outer wall of the connecting shaft 19. By driving the connecting shaft 19 to move, the clamping plate 17 can rotate on the outer wall of the rotating shaft 16, thereby driving the clamping plate 17 and the pressure roller 18 to press and fix the pad. By pressing and fixing the four corners of the pad at the same time, the pad can be stably fixed. After the support plate is fixed, its position can be finely adjusted. By pulling the handle on the outer wall of the positioning frame body 3, the positioning frame body 3 slides on the outer wall of the limiting strip 1101. At the same time, according to the scale displayed on the upper surface of the scale plate 2, the positioning frame is moved to the appropriate position. Pulling the locking pin 8 can compress the second spring 10, which in turn causes the sliding piece 9 to slide inside the positioning block 4. When the locking pin 8 slides out of the sliding pin 5, the rebound of the first spring 6 can cause the sliding pin 5 to slide inside the positioning block 4, and at the same time, it causes the positioning plate 7 to slide into the scale plate 2, achieving the effect of locking the scale plate 2. As a result, the position of the positioning frame body 3 is finely adjusted and then limited. At this time, the fixing component 11 is installed on both sides of the positioning frame body 3. By driving the fixing plate 1102 to slide on the outer wall of the limiting strip 1101, when the fixing plate 1102 is in contact with the positioning frame body 3, the fixing plate 1102 is connected to the base plate 1 by rotating the bolt 1103, thereby achieving the effect of reinforcing the positioning frame body 3. This positioning frame can not only achieve the effect of stable clamping and fixing of the support pad, avoiding the pad from shifting, but also achieve the effect of finely adjusting and limiting the position of the positioning frame, thus improving the accuracy of the positioning frame.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
