Description

Technical Field

[0001] This utility model relates to the field of cold storage technology, specifically to a pad for the column base of a cold storage steel structure. Background Technology

[0002] Cold storage facilities are specialized buildings used for storing goods at low temperatures. Equipped with refrigeration systems, they can precisely control temperature, extending the shelf life and quality of goods. Column base blocks are key components in the cold storage building structure used to support and fix the column bases. They play a vital role in transferring the load from the superstructure, adjusting the column base elevation, accommodating uneven foundation settlement, and protecting the column bases from corrosion. In cold storage facilities, which have strict requirements for environmental conditions such as temperature and humidity, the performance and quality of the column base blocks directly affect the safety and stability of the overall cold storage structure.

[0003] In practical use, traditional cold storage column legs are directly inserted into pre-drilled slots inside a support block. This allows the support block to be placed beneath the column leg for support and protection. However, the connection between the support block and the column leg is merely a matter of removing the slot from the outer wall of the column leg. There are no other supporting or reinforcing structures to stabilize the connection. Furthermore, if the slot inside the support block is too large, the column leg is prone to wobbling after insertion, affecting the overall stability of the cold storage unit. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a pad for the steel structure column base of cold storage. This solves the problem that when the column base of a cold storage is used, its bottom is directly inserted into a pre-cut slot inside the pad, allowing the pad to be placed under the column base for load-bearing and protection. However, in this process, the connection between the pad and the column base is merely to remove the mutual contact between the slot and the outer wall of the column base. Not only is there no other supporting and reinforcing structure to stabilize the connection between the column base and the pad, but if the slot inside the pad is too large, the column base is prone to shaking inside the slot after being inserted, thus affecting the overall stability of the cold storage.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a steel structure column base pad for cold storage is designed, including a protective pad and a support column. Both the protective pad and the support column are made of polyurethane glass fiber composite material. The feature is that a hollow frame is fixedly installed on the top of the protective pad, a transmission frame is fixedly installed in the middle of the side of the hollow frame, and a placement groove is vertically opened in the middle of both the protective pad and the hollow frame, and the support column is slidably inserted into the placement groove.

[0006] A clamping mechanism is provided at the top of the hollow frame, and a rotating mechanism is provided inside the hollow frame, with the rotating mechanism and the clamping mechanism being connected in a transmission manner.

[0007] The hollow frame and the transmission frame are equipped with a drive mechanism, and the drive mechanism and the rotation mechanism are connected in a transmission connection.

[0008] Preferably, the clamping mechanism includes a guide plate and a clamping arc plate. Guide plates are fixedly installed on all four sides of the top of the hollow frame. A sliding frame is slidably sleeved on the outer side of each guide plate. A support plate is vertically fixedly installed on the top side of each sliding frame. A connecting frame is detachably installed on the side of the support plate. The side of the connecting frame is fixed to the clamping arc plate. Guide grooves are opened at both ends of the inner side of the sliding frame. Guide sliders are fixedly installed on both sides of the outer side of the guide plate, and the guide sliders are slidably inserted into the guide grooves.

[0009] The rotating mechanism includes a transmission circular plate. A rotating circular plate is rotatably sleeved inside the hollow frame via bearings. The rotating circular plate has four sets of abutting grooves inside. A transmission rod is vertically fixedly installed at the bottom center of each connecting frame. The transmission rod is slidably inserted into the abutting groove. A limit baffle is fixedly installed at the bottom of each transmission rod. The top surface of the limit baffle is movably attached to the outer wall of the bottom surface of the rotating circular plate. A movable groove is opened on the bottom side of the guide plate. The top of the transmission rod is slidably installed inside the movable groove.

[0010] The driving mechanism includes a rotating circular plate, a follower gear ring fixedly sleeved at the middle of the outer side of the rotating circular plate, and a rotating rod vertically rotatably mounted at the middle of the inner side of the transmission frame via a bearing. A transmission gear is fixedly sleeved on the outer side of the rotating rod, and the outer side of the transmission gear meshes with the outer side of the follower gear ring.

[0011] A connecting plate is fixedly installed on the top of the rotating rod, and the connecting plate is rotatably set on the outer side of the top of the transmission frame. A tightening bolt is screwed through the middle of the side of the connecting plate by a thread, and the bottom of the tightening bolt is movably attached to the outer side wall of the top of the transmission frame.

[0012] The support plate has insertion holes at both ends of its side, and a connecting bolt is slidably inserted into each insertion hole. The connecting bracket has connecting screw holes at both ends of its side, and the top of the connecting bolt is screwed into the connecting screw hole by a thread.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model features a guide plate on the surface of a hollow frame at the top of a protective pad, and a horizontally movable guide frame on the outside of the guide plate. A rotatable rotating circular plate is simultaneously installed inside the hollow frame. A transmission rod connected to the connecting frame allows the operator to rotate the rod after the support column is vertically inserted into the protective pad through the hollow frame. This rotation drives the transmission gear to rotate within the transmission frame. The meshing of the transmission gear and the follower gear ring simultaneously drives the transmission gear ring and the rotating circular plate to rotate within the hollow frame, while also simultaneously driving the abutting slide groove to rotate. The abutting slide groove then... Under the abutting action of the moving rod, the transmission rod can move horizontally in opposite directions or relative to each other inside the hollow frame as the rotating disc rotates. Subsequently, under the connecting transmission action of the transmission rod, a horizontal pushing and pulling force is synchronously provided to the sliding frame and its side pressing arc plate, so that the pressing arc plate can move horizontally in opposite directions or relative to each other on the outside of the placement slot and the support column. The distance between the pressing arc plates can be adjusted so that they can fully press against and fit against the outer wall of the support column, thereby limiting the movement of the support column and improving the stability of the support column when it is inserted and placed. At the same time, it is convenient to adjust the abutting limit distance according to the support column with different diameters, ensuring the stability of support columns with different diameters when inserted and placed.

[0015] 2. This utility model provides insertion holes at both ends of the support plate and connecting screw holes at both ends of the connecting frame. By connecting bolts passing through the insertion holes and screwing them into the connecting screw holes, the connecting frame and support plate can be separated or connected when the connecting bolts are loosened. This allows for the disassembly and assembly of the clamping arc plate, facilitating the operator to replace clamping arc plates of different curvatures according to the diameter of the support column. This ensures that after horizontal spacing adjustment, the side of the clamping arc plate tightly adheres to the outer wall of the support column, guaranteeing the stability of the clamping arc plate's movement limit on the support column.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A type of base pad for steel structure columns in cold storage, see [link / reference] Figures 1 to 4 Both the protective pad 1 and the support column 12 are made of polyurethane glass fiber composite material. Since the polyurethane glass fiber composite material is used in the column base pad of the cold storage steel structure, it can solve the problem of cold breakage caused by the direct connection between the column base and the reinforced concrete. At the same time, the use of polyurethane glass fiber composite material can improve the durability and service life of the material. A hollow frame 11 is fixedly installed on the top of the protective pad 1, and a transmission frame 3 is fixedly installed in the middle of the side of the hollow frame 11. The protective pad 1 and the hollow frame 11 are both vertically provided with placement grooves 13 in the middle, and the support column 12 is slidably inserted into the placement groove 13.

[0027] For details, see Figures 1 to 4 The support plate 22 has insertion holes 4 at both ends of its side, and a connecting bolt 41 is slidably inserted into each insertion hole 4. The connecting bracket 23 has connecting screw holes 42 at both ends of its side, and the top of the connecting bolt 41 is screwed into the connecting screw hole 42 by thread.

[0028] When constructing a steel structure cold storage facility using support columns 12 and protective pads 1, a clamping arc plate 24 is selected that matches the outer arc surface of the support column 12, based on the diameter of the support column 12. Then, the outer wall of the connecting frame 23 on the side of the clamping arc plate 24 is attached to the outer wall of the support plate 22. The connecting bolt 41 is then pushed through the insertion hole 4, so that its side end is on the outer wall of the connecting bolt hole 42. The connecting bolt 41 is continuously tightened until its side end is fully tightened inside the connecting frame 23. The clamping arc plate 24 is then installed on the outside of the connecting frame 23 and the sliding frame 21. The protective pad 1 is then placed at the bottom of the support column 12, so that the support column 12 passes through the placement groove 13 and is placed inside the hollow frame 11 and the protective pad 1, so that the clamping arc plate 24 is located on the four sides of the outer wall of the support column 12.

[0029] Further, see Figures 1 to 4 A connecting plate 33 is fixedly installed on the top of the rotating rod 31, and the connecting plate 33 is rotatably disposed on the outer side of the top of the transmission frame 3. A tightening bolt 34 is threaded through the middle of the side of the connecting plate 33, and the bottom of the tightening bolt 34 is movably attached to the outer side wall of the top of the transmission frame 3.

[0030] Tighten the clamping bolt 34 to move it inside the connecting plate 33 until the bottom end of the clamping bolt 34 moves away from the outer wall of the top surface of the transmission frame 3, so that the clamping bolt 34 loses its abutting and limiting force on the connecting plate 33 and the rotating rod 31. After the clamping arc plate 24 is fully attached to the outer wall of the support column 12 to abut and limit the movement of the support column 12, the clamping bolt 34 can be tightened to make it descend vertically until the bottom surface of the clamping bolt 34 is fully attached to the outer wall of the top of the transmission frame 3, abutting and limiting the movement of the connecting plate 33 and the rotating rod 31, preventing the rotating rod 31 from rotating arbitrarily and affecting the stability of the abutting arc plate 24 in abutting and limiting the movement of the support column 12.

[0031] It is worth noting that, see Figures 1 to 4 A follower gear ring 29 is fixedly sleeved on the outer middle of the rotating circular plate. Several sets of tooth blocks are arranged on the outer side of the follower gear ring 29. A rotating rod 31 is vertically rotatably installed in the middle of the inner side of the transmission frame 3 through a bearing. The rotating rod 31 rotates and extends from the top of the transmission frame 3 to its outer side. A transmission gear 32 is fixedly sleeved on the outer side of the rotating rod 31. The outer side of the transmission gear 32 meshes with the outer side of the follower gear ring 29. The transmission gear 32 penetrates the side wall of the hollow frame 11 and rotates and extends from the inside of the transmission frame 3 to the inside of the hollow frame 11.

[0032] After the rotating rod 31 is turned, it drives the transmission gear 32 to rotate synchronously inside the transmission frame 3 and the side inside the hollow frame 11. Combined with the meshing transmission of the transmission gear 32 and the follower gear ring 29, the follower gear ring 29 can be driven to rotate synchronously inside the hollow frame 11, which facilitates the synchronous adjustment of the horizontal position of the pressing arc plate 24.

[0033] It is worth noting that, see Figures 1 to 4The hollow frame 11 has guide plates 2 fixedly installed on all four sides of its top. Each guide plate 2 has a sliding frame 21 slidably sleeved on its outer side. Each sliding frame 21 has a support plate 22 vertically fixedly installed on its top side. A connecting frame 23 is detachably installed on the side of the support plate 22. The side of the connecting frame 23 is fixed to a pressing arc plate 24. Guide grooves 5 are opened at both ends of the inner side of the sliding frame 21. Guide sliders 51 are fixedly installed on both sides of the outer side of the guide plate 2. The guide sliders 51 are slidably inserted into the guide grooves 5. The vertical cross-sections of the guide sliders 51 and the guide grooves 5 are both T-shaped.

[0034] The hollow frame 11 has a rotating circular plate rotatably connected to it via a bearing. The rotating circular plate has a sliding groove 26 inside, and there are four sets of sliding grooves 26. Each connecting frame 23 has a transmission rod 27 vertically fixedly installed at the bottom center, and the transmission rod 27 slides through and is inserted into the sliding groove 26. Each transmission rod 27 has a limit baffle 28 fixedly installed at the bottom, and the top surface of the limit baffle 28 is movably attached to the outer wall of the bottom surface of the rotating circular plate. The guide plate 2 has a movable groove 52 on its bottom side, and the top of the transmission rod 27 is slidably installed inside the movable groove 52.

[0035] After the rotating rod 31 is turned, under the meshing transmission action of the transmission gear 32 and the follower gear ring 29, the abutting groove 26 can be driven to rotate synchronously. Under the abutting action of the abutting groove 26 on the transmission rod 27, the transmission rod 27 can move horizontally inside the hollow frame 11 synchronously or relative to the rotation of the rotating disc. Subsequently, under the connecting transmission action of the transmission rod 27, a corresponding horizontal pushing force can be provided to the sliding frame 21. Combined with the guide sliders 51 on both sides of the guide plate 2 and Under the mutual guidance of the guide grooves 5 on both sides inside the sliding frame 21, the sliding frame 21 located on the top four sides of the hollow frame 11 can move horizontally in opposite directions in sync. This causes the pressing arc plate 24 to move horizontally towards the outside of the support column 12 until the side of the pressing arc plate 24 is fully and tightly attached to the outer wall of the support column 12. The spacing between the pressing arc plates 24 is adjusted so that they can fully press against the outer wall of the support column 12, thereby limiting the movement of the support column 12 and improving the stability of the support column 12 during insertion.
