Description

Technical Field

[0001] This utility model relates to the field of elevator shaft technology, and in particular to a prefabricated stainless steel structure elevator shaft device. Background Technology

[0002] Prefabricated stainless steel elevator shaft systems are mainly composed of stainless steel columns and beams. The columns are typically made of high-strength stainless steel tubing, whose excellent corrosion resistance ensures long-term stable use in various complex environments. One of its biggest advantages is its fast installation speed. Compared to traditional concrete or steel shafts, where components are prefabricated in the factory and then transported to the site for assembly, a skilled installation team can complete the frame construction within days, whereas traditional structures may take weeks. Stainless steel itself has excellent corrosion resistance, effectively resisting the erosion of atmospheric moisture, dust, and chemical substances in elevator shafts, which are exposed to the environment for extended periods.

[0003] A search revealed Chinese Patent Publication No. CN221372998U, which discloses an elevator shaft protection device. The device includes a support frame covered with a first protective net. Connectors are arranged around the support frame, with one end connected to the outer frame and the other end connected to an adapter. The adapter is fixed to the inner wall of the elevator shaft. A second protective net is rotatably arranged around the support frame, positioned above the connectors, and inclined against the inner wall of the elevator shaft to cover the gap between the support frame and the inner wall. The beneficial effects of this technical solution are: the adapter can be bolted to the inner wall of the elevator shaft, providing adhesion for subsequent equipment; and the second protective net can rotate to adapt to different gaps after the first protective net is fixed, ensuring the elevator shaft is safely covered. However, while this device achieves the effect of adapting to different gaps and ensuring the elevator shaft is safely covered, it cannot solve the problem of buffering the elevator's descent. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a prefabricated stainless steel elevator shaft device, which aims to improve the problem of malfunctions and accidents caused by excessive elevator descent speed in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated stainless steel elevator shaft device, comprising a frame, upper baffles fixedly connected to adjacent bottoms of the frame, multiple support blocks fixedly connected to the bottom perimeter of the upper baffles, springs II fixedly connected to the bottom edge of the support blocks, multiple rotating rods rotatably connected to the front and rear ends of the support blocks, sliders fixedly connected to the other ends of the rotating rods, fixed rods slidably connected inside the sliders, multiple springs I slidably connected to the front and rear ends of the outer walls of the fixed rods, spring III fixedly connected to the bottom of the support blocks near the middle, and multiple disassembly mechanisms provided around the bottom perimeter of the frame for disassembly and installation.

[0006] The above technical solution includes a frame with an upper baffle fixedly connected to adjacent positions at the bottom of the frame. Multiple support blocks are fixedly connected to the bottom perimeter of the upper baffle. Spring 2 is fixedly connected to the bottom edge of these support blocks. Multiple rotating rods are rotatably connected to the front and rear ends of the support blocks. A slider is fixedly connected to the other end of each rotating rod. A fixed rod is slidably connected inside the slider. Multiple spring 1 is slidably connected to the front and rear ends of the outer wall of the fixed rod. In addition, spring 3 is fixedly connected to the bottom of the support block near the middle. To facilitate disassembly and installation, multiple disassembly mechanisms are provided around the bottom perimeter of the frame. These disassembly mechanisms are specially designed for disassembly and installation, ensuring the stability of the frame structure and ease of operation.

[0007] As a further description of the above technical solution:

[0008] The disassembly mechanism includes a side baffle. The top four sides of the side baffle are fixedly connected to the bottom of the frame. A threaded hole 1 is provided on the left front end of the side baffle. Multiple threaded holes 2 are provided on the right side of the side baffle. An L-shaped stop block is slidably connected between adjacent side baffles. A threaded hole 3 is provided on the inner wall of the L-shaped stop block. A hexagonal screw is threaded to the inner wall of the threaded hole 3.

[0009] Through the above technical solution: the disassembly mechanism includes a side baffle, the top edge of which is tightly and firmly connected to the bottom of the frame, ensuring that the side baffle remains stable during disassembly and will not shift due to external forces. Furthermore, a threaded hole 1 is opened at the front left end of the side baffle, which allows other components to be fixed to the side baffle by threaded connection, thereby achieving the purpose of disassembly or assembly. In addition, multiple threaded holes 2 are opened on the right side of the side baffle, which provide additional connection points for the disassembly mechanism, making the disassembly process more flexible. To further enhance the function of the disassembly mechanism, L-shaped blocks are designed between adjacent side baffles. These L-shaped blocks can slide along the length of the side baffle. Threaded holes 3 are opened on the inner wall of the L-shaped blocks. These threaded holes 3 are used in conjunction with hexagonal screws. By screwing the hexagonal screws into the threaded holes 3, the L-shaped blocks can be effectively fixed in a specific position.

[0010] As a further description of the above technical solution:

[0011] Each of the multiple support blocks is fixedly connected to an adjacent support bridge, and the top of the support bridge is fixedly connected to the bottom of the upper baffle.

[0012] Through the above technical solution, multiple support blocks are fixedly connected by connecting bridges. These connecting bridges not only ensure the stability between the support blocks and the robustness of the overall structure, but also firmly connect their top parts to the bottom of the upper baffle, so that the entire structure can remain stable when bearing weight and pressure. At the same time, the tight connection between the upper baffle and the support blocks through the connecting bridges further enhances the integrity and durability of the structure.

[0013] As a further description of the above technical solution:

[0014] Each of the frames has a base plate fixedly connected to its bottom adjacent to each other, and a crossbar is fixedly connected to the right side of the frame near the middle.

[0015] Through the above technical solution: the bottom of each of the multiple frames is fixedly connected to a base plate, which can ensure a stable and tight connection between the frames. The base plate not only enhances the stability of the structure, but also provides additional support for the entire frame structure, thereby improving its load-bearing capacity. In addition, a crossbar is fixedly connected to the right side of the frame near the middle. The addition of the crossbar further enhances the lateral stability of the frame, making the entire structure more stable when subjected to lateral forces. The crossbar can also effectively prevent the frame from moving laterally during use, thereby ensuring safety and reliability during use.

[0016] As a further description of the above technical solution:

[0017] The bottom of the spring three is fixedly connected to a fixing block one, and the bottom of the multiple fixing blocks one is fixedly connected to the front and rear sides of the top inner wall of the base plate.

[0018] Through the above technical solution: the bottom of spring three is fixedly connected to fixed block one. This design ensures the stability of spring three. In addition, the bottom of multiple fixed blocks one is firmly fixedly connected to the front and rear sides of the inner wall of the base plate. This connection method not only enhances the stability of the entire structure, but also ensures that spring three and fixed block one can withstand greater forces without displacement during use, thereby ensuring the normal operation and service life of the equipment.

[0019] As a further description of the above technical solution:

[0020] The bottom of the second spring is fixedly connected to a second fixing block, and the bottom of the multiple second fixing blocks is fixedly connected to the top left and right sides of the inner wall of the base plate.

[0021] Through the above technical solution: the bottom of spring two is fixedly connected to fixed block two. This connection method ensures the stability of spring two. In addition, the bottom of multiple such fixed blocks two is fixedly connected to the top left and right sides of the inner wall of the base plate. This structural design not only enhances the stability of the entire device, but also ensures a firm connection between spring two and fixed block two, thereby improving the load-bearing capacity and durability of the entire device.

[0022] As a further description of the above technical solution:

[0023] A top plate is fixedly connected to the top of the frame, and an upper connecting rod is fixedly connected to the front side of the frame near the upper end.

[0024] Through the above technical solution: the top part of the frame is fixedly connected to the top plate. This design can provide additional stability and support. In addition, in order to further enhance the stability of the structure, the front area of ​​the frame is specifically fixedly connected to the upper part. This connection method not only ensures the overall strength of the frame, but also provides mounting points for possible additional components, thereby increasing the versatility of the frame.

[0025] As a further description of the above technical solution:

[0026] A fixing block 2 is fixedly connected to the lower middle side of the frame, and a diagonal rod is fixedly connected to the left side of the frame near the middle.

[0027] Through the above technical solution: a fixing block two is fixedly connected to the lower middle part of the frame. The function of this fixing block two is to provide additional stability and support to ensure the stability of the entire frame structure. In addition, in order to further enhance the stability and functionality of the structure, a diagonal bar is fixedly connected to the left side of the frame near the middle. The diagonal bar increases the strength of the frame.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, when the elevator descends and abuts against the upper baffle, the pressure is distributed to the support block. At this time, the downward pressure causes the second spring to press down, squeezing the rotating rod on both sides. This causes the slider to move on the fixed rod, while simultaneously pushing the first spring to move to both sides, achieving a shock absorption effect. At the same time, the support block compresses the third spring, deforming it. When the external force disappears, the third spring, the first spring, and the second spring return to their original positions, thus achieving the function of buffering the elevator.

[0030] 2. In this utility model, when the internal structure malfunctions, the hexagonal screw is rotated out and removed from the threaded hole three of the L-shaped stop and the threaded hole two of the side baffle. At this time, the L-shaped stop can be taken out, and the side baffle can be disassembled. After maintenance, the threaded hole three on the L-shaped stop is aligned with the threaded hole two of the side baffle, and the hexagonal screw is rotated in. At this time, the elevator can be used normally, realizing the function of disassembling the side baffle for maintenance when the internal structure malfunctions. Attached Figure Description

The bottom of multiple fixing blocks 12 is fixedly connected to the front and rear sides of the top inner wall of the base plate 17.

[0044] Specifically, multiple support blocks 4 are fixedly connected by connecting bridges 5. These connecting bridges 5 not only ensure the stability between the support blocks 4 and the overall structural robustness, but also firmly connect their top parts to the bottom of the upper baffle 3, allowing the entire structure to remain stable under weight and pressure. Simultaneously, the tight connection between the upper baffle 3 and the support blocks 4 through the connecting bridges 5 further enhances the structural integrity and durability. Each of the adjacent bottoms of multiple frames 1 is fixedly connected to a base plate 17, ensuring a stable and tight connection between the frames 1. The base plate 17 not only enhances the structural stability but also provides additional support for the entire frame 1 structure, thereby increasing its load-bearing capacity. Furthermore, the right side of the frame 1 near the center is fixed... A crossbar 18 is fixedly connected, which further enhances the lateral stability of the frame 1, making the entire structure more stable when subjected to lateral forces. The crossbar 18 also effectively prevents the frame 1 from moving laterally during use, thus ensuring safety and reliability. The bottom of spring 3 10 is fixedly connected to fixed block 1 12, which ensures the stability of spring 3 10. In addition, the bottoms of multiple fixed blocks 1 12 are firmly fixedly connected to the top front and rear sides of the inner wall of the base plate 17. This connection method not only enhances the stability of the entire structure, but also ensures that spring 3 10 and fixed block 1 12 can withstand greater forces without displacement during use, thus ensuring the normal operation and service life of the equipment.

[0045] Please see the appendix Figure 1 - Appendix Figure 3 The bottom of spring 29 is fixedly connected to fixing block 2 13. The bottom of multiple fixing blocks 2 13 is fixedly connected to the top left and right sides of the inner wall of the base plate 17.

The left side of the frame 1 is fixedly connected to the diagonal bar 15 near the middle part of the upper part of the upper part of the upper part of the frame 1, which improves the overall stability.

[0046] Specifically, the bottom of spring 29 is fixedly connected to fixed block 213, ensuring the stability of spring 29 and effectively transmitting force. The bottoms of multiple fixed blocks 213 are fixedly connected to the top left and right sides of the inner wall of the base plate 17, enhancing the stability of the entire device. The top of the frame 1 is designed to be fixedly connected to the top plate 16, which makes the entire device more stable in the vertical direction and able to withstand greater pressure and impact. To further enhance the stability of the device, an upper connecting rod 14 is fixedly connected to the front side of the frame 1 near the upper end. This design not only increases the rigidity of the device but also improves its overall structural strength. Fixed block 213 is also designed in the lower middle part of the frame 1, which helps to disperse and support the pressure from above, ensuring the stability and safety of the device during use.

[0047] Working principle: When the elevator descends, it blocks the upper baffle 3. At this time, the upper baffle 3 distributes the pressure to the support block 4. The support block 4 presses down, causing the second spring 9 to press down. At the same time, the support block 4 squeezes the rotating rod 6 to both sides. The rotating rod 6 drives the slider 7 to move. The slider 7 moves on the fixed rod 11 and pushes the first spring 8 to both sides to achieve the effect of shock absorption. At the same time, the support block 4 compresses the third spring 10 to deform. When the external force disappears, the third spring 10, the first spring 8 and the second spring 9 return to their original state, thus achieving the function of buffering the elevator.

[0048] When an internal structure malfunctions, the hex screw 206 is rotated out and removed from the threaded hole 205 of the L-shaped stop 202 and the threaded hole 204 of the side baffle 201. The L-shaped stop 202 can then be removed, allowing the side baffle 201 to be disassembled. After maintenance, the threaded hole 205 on the L-shaped stop 202 is aligned with the threaded hole 204 on the side baffle 201, and the hex screw 206 is rotated back in. The elevator can then be used normally, thus enabling the side baffle 201 to be disassembled for maintenance when an internal structure malfunctions.
