Description

Technical Field

[0001] The invention relates to the technical field of spiral staircases, in particular to a combined spiral staircase assembly for a concrete mixing station with a double-sided protective structure. Background Art

[0002] In the past, in the design of industrial building stairs, traditional straight stairs were widely used because of their high safety and strong applicability. However, since traditional straight stairs occupy a large area, they also need to set up multiple platforms and openings of different specifications and positions according to the needs of production processes. Therefore, the staircase layout process is very cumbersome and the design drawings are also very complicated. For this reason, the use of spiral staircases in building staircase design is gradually increasing.

[0003] At present, most existing spiral staircases adopt a semi-open design during production, in which the steps are spirally welded along the surface of the column and then the handrails are welded on the other side of the steps for protection. Such protective handrails are mostly designed to be only half the height of a normal adult, which results in that the user cannot be well protected during use. In addition, most spiral staircases are not equipped with a buffer platform during the climbing process, which makes it easy for the user to accidentally fall and cause serious fall injuries, thereby endangering the safety of the user. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a combined spiral staircase assembly for a concrete mixing plant with a double-sided protective structure, which solves the problem that the existing spiral staircases mentioned in the above background technology have a weak protective structure on the sides when in use.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a combined spiral staircase assembly for a concrete mixing plant with a double-sided protective structure, including a mounting base, a support rod is fixedly installed on the upper end of the mounting base, support columns are installed on the left and right sides of the upper end of the mounting base, the upper ends of each of the support columns and the support rods are installed with the same capping plate, the outer surface of the capping plate is fixedly installed with a mounting frame, the outer surface of each of the support columns is sleeved with a plurality of clamping rings, the side ends of each of the clamping rings are fixedly installed with pedals, the lower end of the mounting frame is installed with a plurality of first protective rods, the lower end of each of the first protective rods is installed with a second protective rod, the outer surfaces of each of the first protective rods and the second protective rods are sleeved with a sleeve column, and the side ends of every two adjacent mounting frames are installed with the same protective plate.

[0006] Optionally, guide plates are fixedly mounted on both the front and rear sides of the mounting base, and a plurality of first threaded holes are formed on the upper end of the mounting base.

[0007] Optionally, two second threaded holes are provided at the upper end of the mounting base, a first thread line is engraved on the outer surface of each support column, and each support column is mounted above the mounting base through the first thread line and the second threaded hole.

[0008] Optionally, a limit plate is fixedly installed on the upper end of the support rod, and a limit strip is fixedly installed on the lower end of the capping plate. The capping plate is slidably installed above the support rod and the support column through the limit strip and the limit plate.

[0009] Optionally, extension plates are fixedly mounted on both the front and rear sides of the capping plate, a mounting frame is sleeved on the outer surface of each extension plate, and a plurality of third threaded holes are formed at the lower end of each mounting frame.

[0010] Optionally, the upper end of each first protection rod is engraved with a second thread line, and the lower end of each second protection rod is engraved with a third thread line.

[0011] Optionally, each of the first protective rods is installed below the mounting frame through the cooperation of the second thread line and the third threaded hole, and each of the second protective rods is installed above the mounting base through the cooperation of the third thread line and the first threaded hole.

[0012] Optionally, a limiting ring is fixedly installed inside each clamping ring, a supporting leg is fixedly installed at the lower end of each pedal, and a sleeve ring is fixedly installed at the side end of each pedal.

[0013] Optionally, a connecting column is fixedly mounted on the lower end of each of the first protection rods, and each of the first protection rods is mounted on the second protection rod by the connection column cooperating with a groove above the second protection rod.

[0014] Optionally, a bolt is installed on the side end of each sleeve column, and each bolt is installed on the side end of the sleeve column in the opposite direction to the protection plate.

[0015] The present invention provides a combined spiral staircase assembly for a concrete mixing station with a double-sided protective structure, which has the following beneficial effects:

[0016] 1. The combined spiral staircase assembly for a concrete mixing plant with a double-sided protective structure is reinforced by installing a first protective rod and a second protective rod between the installation base and the capping plate, and the capping plate and the extension plate are used as intermediate buffer steps for each layer to continue to be built upward, so that the device can provide high protection for the edge part of the device when in use, and can provide buffering between each layer to reduce falling injuries when going upstairs, thereby ensuring the safety of users when using the device and improving the safety of device use.

[0017] 2. The combined spiral staircase assembly for the concrete mixing station with double-sided protective structure is designed to cooperate with each other through the support column, the capping plate, the clamping ring and the first protective rod, the protective plate, the second protective rod and other parts, so that the device can be easily disassembled in the later stage, thereby facilitating the inspection and replacement of the device and facilitating the disassembly and transportation of the device, thereby improving the use efficiency of the device.

[0018] 3. The combined spiral staircase assembly for the concrete mixing station with a double-sided protective structure is achieved by installing a sleeve column and a protective plate between each first protective rod and the second protective rod and then fixing the sleeve column with bolts to improve the connectivity between devices when the device is in use, thereby improving the stability of the device when in use and further ensuring the safety of the device.

[0019] 4. The combined spiral staircase assembly for the concrete mixing station with double-sided protective structure can quickly install the capping plate by means of the limit strip installed below the capping plate and the limit plate installed above the support rod. At the same time, the support columns on both sides of the support rod can provide support for the capping plate during installation, and the capping plate can limit the top of the support column after installation, so that the device can provide sufficient support when in use, ensuring that the device remains stable during use.

[0020] 5. The combined spiral staircase assembly for a concrete mixing plant with a double-sided protective structure contacts the support column through the internal limiting ring of the clamping ring and cooperates with the lower clamping ring for support, and then cooperates with the first protective rod and the second protective rod to limit the pedal when it is put into use, and then rotate it when not in use for quick use and disassembly and storage, thereby improving the use efficiency of the device.
