Description

Technical Field

[0001] The invention belongs to the technical field of nuclear power engineering building construction, and in particular relates to an edge protection device for the construction of external wall panels of nuclear power engineering buildings. Background Art

[0002] Nuclear power projects are large-scale engineering projects that use the fission reaction of nuclear fuel in nuclear reactors to generate heat energy and then convert it into electrical energy. It usually includes a nuclear island, a conventional island and related supporting facilities. The nuclear island is the core part, which contains key equipment such as reactor pressure vessels and is responsible for the generation and control of nuclear energy. The conventional island converts heat energy into electrical energy. Nuclear power projects have the advantages of being clean, efficient and stable. They can provide electricity on a large scale, reduce dependence on fossil energy and reduce carbon emissions. However, they also face nuclear safety risks. Therefore, there are strict safety standards and regulatory measures in the design, construction, operation and other links to ensure that public safety and the environment are not affected. In the construction of building exterior wall panels, the main function of the edge protection device is to prevent construction personnel and objects from falling from the edge of the building, provide safety protection for construction personnel, reduce the risk of falling accidents from heights, and also avoid damage to surrounding personnel and facilities caused by falling objects, ensuring the safety and order of the construction site.

[0003] In the construction of exterior wall panels, most existing methods use cantilevered protective structures. When the exterior wall panels are installed, they may fall off due to loose fixation or external force. The cantilevered protective shed can intercept them below the working surface to prevent them from falling directly to the ground. At the same time, it can prevent the falling point from being too high, causing the objects to pass through the protection area. However, most existing edge guardrails are simple guardrail structures with relatively single functions. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an edge protection device for the construction of exterior wall panels of nuclear power engineering buildings.

[0005] The technical solution adopted to solve the above technical problems is: to provide an edge protection device for the construction of the exterior wall panels of nuclear power engineering buildings, including a guardrail main body mechanism, the center of the top guardrail main body mechanism is fixedly connected to a central mesh plate mechanism, and both sides of the bottom of the front end of the guardrail main body mechanism are rotatably connected to a bottom bracket mechanism;

[0006] The bottom of the rear end of the guardrail main body mechanism is rotatably connected to an auxiliary protection structure, and a storage drive mechanism is arranged on the top of the guardrail main body mechanism. One end of the storage drive mechanism is fixedly connected to a limiting mechanism, and connecting steel wires are installed between the storage drive mechanism and both sides of the auxiliary protection structure and one end of the two bottom bracket mechanisms.

[0007] Furthermore, the guardrail main body mechanism includes a guardrail support frame, a hollow pillar is fixedly connected between the two ends of the top of the guardrail support frame, a first connection hole plate and a second connection hole plate are fixedly connected to the bottom of both sides of the guardrail support frame, a blocking frame rod is fixedly connected between the first connection hole plate and the second connection hole plate and the side of the guardrail support frame, and connecting shaft seats are provided on both sides of the bottom of the guardrail support frame. When in use, two of the protective devices are spliced ​​together, the first connection hole plates and the second connection hole plates of different heights on both sides of the guardrail support frame are overlapped, and are fixed by bolts through corresponding through holes, and the whole device is fixed to the edge of the cantilever platform and spliced ​​and fixed, and the two bottom bracket mechanisms can be rotatably connected through the two connecting shaft seats.

[0008] Furthermore, the first connection hole plate and the second connection hole plate are not on the same horizontal plane.

[0009] Through the above technical solution, it is ensured that when two protective devices are spliced, the first connecting hole plate and the second connecting hole plate can overlap each other and then be connected and fixed by bolts.

[0010] Furthermore, the central mesh plate mechanism includes a bottom baffle fixedly connected to the guardrail support frame, the top of the bottom baffle is fixedly connected to an integrated frame, and the inner wall of the integrated frame is fixedly connected to a wire protection net.

[0011] Through the above technical solution, some small objects can be prevented from being kicked out by the bottom baffle, and some objects can be effectively prevented from passing through the overall central mesh plate mechanism by the wire protection net.

[0012] Furthermore, the bottom bracket mechanism includes a connecting shaft sleeve seat rotatably connected to the bottom of the front end of the guardrail main body mechanism, the front end surface of the connecting shaft sleeve seat is fixedly connected to a supporting connecting piece, and pressure equalizing plates are provided on both sides of the front end of the supporting connecting piece. Two fixing bolts are passed through the two pressure equalizing plates and the supporting connecting piece, and the front end of the top of the supporting connecting piece is rotatably connected to a first steel wire connecting piece.

[0013] Through the above technical solution, the connecting steel wire is released by the storage drive mechanism to realize the rotation and lowering of the overall bottom bracket mechanism. At this time, the two bottom bracket mechanisms are horizontally placed to fit the platform, and the overall support connector is installed on the nut seat of the platform by fixing bolts.

[0014] Furthermore, the auxiliary protection structure includes a rotating frame rotatably connected to the bottom of the rear end of the guardrail main body mechanism, the bottoms of both sides of the rotating frame are fixedly connected with fixed shaft blocks, the front ends of both sides of the top of the rotating frame are installed with slide groove blocking covers, the inner wall of the rotating frame is installed with a first protection rope net, fixed clamping shafts are provided on both sides of the top of the rotating frame, permanent magnet blocks are fixedly connected to the rear ends of the fixed clamping shafts on both sides of the rotating frame, T-shaped limit rods are fixedly connected to both sides of the inner wall of the rotating frame, a sliding frame is fixedly connected between the tops of the two T-shaped limit rods, iron connecting clamping plates are rotatably connected to both sides of the bottom of the sliding frame, a second protection rope net is installed on the inner wall of the sliding frame, and second steel wire connectors are rotatably connected to both sides of the top of the sliding frame.

[0015] By means of the above technical scheme, the connecting steel wire is released by the storage driving mechanism, and the auxiliary protection structure after the connecting steel wire is released reaches the maximum angle. At this time, the connecting steel wire is pulled to rotate and pull up the auxiliary protection structure, and then the top of the sliding frame is pulled until it slides to the maximum stroke. At this time, the two T-shaped limit rods slide on both sides of the inner wall of the rotating frame until they hit the sliding groove blocking cover. At this time, the two iron connecting clamps are rotated and then engaged with the corresponding fixed clamping shafts. At the same time, the iron connecting clamps are adsorbed by two corresponding permanent magnets to prevent the overall sliding frame from sliding downward, and then the connecting steel wire is released. The opened auxiliary protection structure rotates to the maximum angle under the limitation of the length of the connecting steel wire. The extended auxiliary protection structure can effectively increase the range of the edge protection device and reduce the safety hazard of objects falling from high altitude. When the auxiliary protection structure is hit by an object, the impact force can be transmitted to the guardrail main body mechanism through the connecting steel wire and its own structure, and then transmitted to the two bottom bracket mechanisms through the connecting steel wire, thereby ensuring the stability of the overall device when facing impact.

[0016] Furthermore, sliding grooves corresponding to the T-shaped limiting rods are provided on both sides of the inner wall of the rotating frame.

[0017] Through the above technical solution, the extended sliding frame is supported by the sliding groove and the two T-shaped limiting rods, so that the rotating frame and the sliding frame become a whole.

[0018] Furthermore, the storage drive mechanism includes two side blocking shaft plates installed on both sides of the top of the guardrail main body mechanism, and a connecting shaft rod is rotatably connected between the two side blocking shaft plates, and the first winding wheel and the second winding wheel are fixedly connected to both sides of the outer wall of the connecting shaft rod.

[0019] Through the above technical solution, the connecting shaft is driven to rotate through the limiting mechanism, thereby driving the two first winding wheels and the two second winding wheels to rotate simultaneously, thereby releasing and winding up the connecting steel wire, and then realizing the opening and closing of the auxiliary protection structure and the two bottom bracket mechanisms.

[0020] Furthermore, both the first winding wheel and the second winding wheel have connecting steel wires wound on them, the length of the connecting steel wire on the first winding wheel is shorter than the length of the connecting steel wire on the second winding wheel, and the diameter of the first winding wheel is smaller than the diameter of the second winding wheel.

[0021] Through the above technical solution, since the fully extended auxiliary protection structure is longer, the distance between the first steel wire connector and the storage drive mechanism is smaller than the distance between the second steel wire connector and the storage drive mechanism, so the connecting steel wires between the two are different. At the same time, in order to ensure that the first winding wheel and the second winding wheel have the same number of rotations, the two connecting steel wires of different lengths can be fully released at the same time. Therefore, the longer connecting steel wire is designed to be wound on the second winding wheel with a larger diameter, and the shorter connecting steel wire is wound on the first winding wheel with a smaller diameter.

[0022] Furthermore, the limiting mechanism includes a fixed circular sleeve fixedly connected to one side of the side blocking shaft plate and an integrated square groove seat fixedly connected to one end of the connecting shaft rod, a rotating circular block is rotatably connected to one side of the inner wall of the fixed circular sleeve, a square latch is fixedly connected to the rotating circular block at the center of one side close to the integrated square groove seat, an extension rod is fixedly connected to the outer wall of the rotating circular block, an adjusting block is rotatably connected to the outer wall of the extension rod, a return spring is arranged between the integrated square groove seat and the rotating circular block, a rotating limit block is fixedly connected to the other side of the outer wall of the fixed circular sleeve, and the fixed circular sleeve is provided with a slot corresponding to the rotating limit block.

[0023] Through the above technical solution, after the initial fixation is completed, the adjusting block is rotated, and the overall rotating round block is pulled outward, and the reset spring is stretched, and the rotating limit block is pulled out of the groove at the same time. The rotating adjusting block is placed horizontally to limit the position of the rotating round block after it is pulled out, so as to avoid the rotating round block from being reset under the action of the reset spring, and then the rotating round block is driven to rotate by the extension rod, and then the square pin is engaged inside the integrated square groove seat to drive the integrated square groove seat and the connecting shaft rod fixedly connected thereto to rotate, so as to release the auxiliary protection structure and the bottom bracket mechanism, and the rotating round block is driven to rotate in the reverse direction when the overall protection device is subsequently disassembled, so as to drive the two first winding wheels and the two second winding wheels to reel in the multiple connecting wires, until the rotating adjusting block is in a vertical state after being fully reeled in, and under the action of the reset spring, the rotating round block retracts at this time, and the rotating limit block is clamped into the slot at the same time, so as to limit the rotation of the rotating round block, and then limit the connecting shaft rod, so as to avoid the connecting shaft rod from rotating to cause the bottom bracket mechanism and the auxiliary protection structure to deflect.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention can effectively increase the range of the edge protection device by designing a retractable and extendable auxiliary protection structure, reducing the safety hazard of objects falling from high altitudes. When the auxiliary protection structure is hit by an object, the impact force can be transmitted to the guardrail main body mechanism through the connecting steel wire and its own structure, and then transmitted to the two bottom bracket mechanisms through the connecting steel wire, thereby ensuring the stability of the entire device when facing an impact. At the same time, the retractable auxiliary protection structure can be stored by the guardrail main body mechanism after retracting, while improving the functionality of the overall protection device without increasing the space occupied by the overall protection device; (2) The present invention drives the bottom bracket mechanism and the auxiliary protection structure at the same time by designing a storage drive mechanism and a connecting steel wire. The bottom bracket mechanism and the auxiliary protection structure can be released and stored at the same time, which greatly improves the installation efficiency and disassembly and recovery efficiency of the device, ensures diverse functions without increasing additional installation and recovery time, and improves work efficiency.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0048] like Figure 1-Figure 3As shown, an edge protection device for the construction of the exterior wall panels of a nuclear power engineering building of this embodiment includes a guardrail main body mechanism 1, and the guardrail main body mechanism 1 includes a guardrail support frame 101, and a hollow pillar 102 is fixedly connected between the two ends of the top of the guardrail support frame 101, and the bottoms of both sides of the guardrail support frame 101 are respectively fixedly connected with a first connection hole plate 103 and a second connection hole plate 104, and the first connection hole plate 103 and the second connection hole plate 104 are fixedly connected to the side of the guardrail support frame 101. A blocking frame rod 105 is fixedly connected between the first connection hole plate 103 and the second connection hole plate 104 and the side of the guardrail support frame 101, and a connecting shaft seat 106 is arranged on both sides of the bottom of the guardrail support frame 101. When in use, The two protective devices are spliced ​​together, and the first connecting hole plates 103 and the second connecting hole plates 104 at different heights on both sides of the guardrail support frame 101 are overlapped with each other, and fixed by bolts passing through corresponding through holes, and the entire device is fixed to the edge of the cantilever platform and spliced ​​and fixed. The two bottom bracket mechanisms 3 can be rotatably connected through two connecting shaft seats 106. The first connecting hole plates 103 and the second connecting hole plates 104 are not on the same horizontal plane, which ensures that when the two protective devices are spliced ​​together, the first connecting hole plates 103 and the second connecting hole plates 104 can overlap with each other and be connected and fixed by bolts.

[0049] like Figure 1-Figure 5 As shown, the center of the top guardrail main body mechanism 1 is fixedly connected to a central mesh plate mechanism 2, and the central mesh plate mechanism 2 includes a bottom baffle 201 fixedly connected to the guardrail support frame 101, and the top of the bottom baffle 201 is fixedly connected to an integrated frame 202, and the inner wall of the integrated frame 202 is fixedly connected to a wire protection net 203, and the bottom baffle 201 can prevent some small objects from being kicked out, and the wire protection net 203 can effectively prevent some objects from passing through the overall central mesh plate mechanism 2, and the bottom sides of the front end of the guardrail main body mechanism 1 are rotatably connected to the bottom bracket mechanism 3, and the bottom bracket mechanism 3 includes a bottom bracket mechanism 3 rotatably connected to the guardrail main body mechanism 1 A connecting shaft sleeve seat 301 at the bottom of the front end, the front end surface of the connecting shaft sleeve seat 301 is fixedly connected with a supporting connector 302, and pressure equalizing plates 303 are arranged on both sides of the front end of the supporting connector 302. Two fixing bolts 304 are passed through the two pressure equalizing plates 303 and the supporting connector 302, and the front end of the top of the supporting connector 302 is rotatably connected with a first steel wire connector 305. The connecting steel wire 7 is released by the storage drive mechanism 5 to realize the rotation and lowering of the overall bottom bracket mechanism 3. At this time, the two bottom bracket mechanisms 3 are horizontally placed to fit the platform, and the overall supporting connector 302 is installed on the nut seat of the platform through the fixing bolts 304.

[0050] like Figure 1-Figure 10As shown, the bottom of the rear end of the guardrail main body mechanism 1 is rotatably connected to an auxiliary protection structure 4, and the auxiliary protection structure 4 includes a rotating frame 401 rotatably connected to the bottom of the rear end of the guardrail main body mechanism 1, the bottoms of both sides of the rotating frame 401 are fixedly connected to fixed shaft blocks 402, the front ends of both sides of the top of the rotating frame 401 are installed with slide groove blocking covers 403, the inner wall of the rotating frame 401 is installed with a first protection rope net 404, both sides of the top of the rotating frame 401 are provided with fixed clamping shafts 405, and both sides of the rotating frame 401 are fixedly connected to permanent magnet blocks 406 at the rear ends of the fixed clamping shafts 405. Both sides of the inner wall of the frame 401 are fixedly connected with T-shaped limit rods 410, and a sliding frame 407 is fixedly connected between the tops of the two T-shaped limit rods 410. Both sides of the bottom of the sliding frame 407 are rotatably connected with iron connecting clamps 408. The inner wall of the sliding frame 407 is installed with a second protective rope net 409, and both sides of the top of the sliding frame 407 are rotatably connected with second steel wire connectors 411. The connecting steel wire 7 is released by the storage drive mechanism 5. The auxiliary protection structure 4 after the connecting steel wire 7 is released reaches the maximum angle. At this time, the connecting steel wire 7 is pulled to rotate and pull up the auxiliary protection structure 4, and then the connecting steel wire 7 is pulled up. The top of the movable sliding frame 407 is moved until it slides to the maximum stroke. At this time, the two T-shaped limit rods 410 slide on both sides of the inner wall of the rotating frame 401 until they hit the slide slot blocking cover 403. At this time, the two iron connecting clamps 408 are rotated and then engaged with the corresponding fixed clamping shafts 405. At the same time, the iron connecting clamps 408 are adsorbed by two corresponding permanent magnet blocks 406 to prevent the overall sliding frame 407 from sliding downward, and then the connecting wire 7 is released. The opened auxiliary protection structure 4 is rotated to the maximum angle under the limitation of the length of the connecting wire 7. The extended auxiliary protection structure 4 can effectively increase the edge defense The scope of the protective device reduces the safety hazard of objects falling from high altitudes. When the auxiliary protective structure 4 is hit by an object, the impact force can be transmitted to the guardrail main body mechanism 1 through the connecting steel wire 7 and its own structure, and then transmitted to the two bottom bracket mechanisms 3 through the connecting steel wire 7, thereby ensuring the stability of the entire device when facing an impact. Sliding grooves corresponding to the T-shaped limit rods 410 are provided on both sides of the inner wall of the rotating frame 401. The sliding grooves and the two T-shaped limit rods 410 are used to provide support for the extended sliding frame 407, so that the rotating frame 401 and the sliding frame 407 become a whole.

[0051] like Figure 1-Figure 15As shown, a storage drive mechanism 5 is provided on the top of the guardrail main body mechanism 1, and the storage drive mechanism 5 includes two side blocking shaft plates 501 installed on both sides of the top of the guardrail main body mechanism 1, and a connecting shaft rod 502 is rotatably connected between the two side blocking shaft plates 501, and the first winding wheel 503 and the second winding wheel 504 are fixedly connected on both sides of the outer wall of the connecting shaft rod 502. The rotation of the connecting shaft rod 502 is driven by the limiting mechanism 6, and then the two first winding wheels 503 and the two second winding wheels 504 are driven to rotate simultaneously, so as to realize the release and winding of the connecting steel wire 7, and then realize the opening and closing of the auxiliary protection structure 4 and the two bottom bracket mechanisms 3. The connecting steel wire 7 is wound on the first winding wheel 503 and the second winding wheel 504. The length of the connecting steel wire 7 is smaller than the length of the connecting steel wire 7 on the second winding wheel 504, and the diameter of the first winding wheel 503 is smaller than the diameter of the second winding wheel 504. Since the fully extended auxiliary protection structure 4 is longer, the distance between the first steel wire connector 305 and the storage drive mechanism 5 is smaller than the distance between the second steel wire connector 411 and the storage drive mechanism 5. Therefore, the connecting steel wires 7 between the two are different. At the same time, in order to ensure that the first winding wheel 503 and the second winding wheel 504 have the same number of rotations, the two connecting steel wires 7 of different lengths can be fully released at the same time. Therefore, the longer connecting steel wire 7 is designed to be wound on the second winding wheel 504 with a larger diameter, and the shorter connecting steel wire 7 is wound on the first winding wheel 503 with a smaller diameter.

[0052] like Figure 1-Figure 21As shown, one end of the storage driving mechanism 5 is fixedly connected to the limiting mechanism 6, and the limiting mechanism 6 includes a fixed circular sleeve 601 fixedly connected to one side of the side blocking shaft plate 501 and an integrated square groove seat 602 fixedly connected to one end of the connecting shaft rod 502. A rotating circular block 604 is rotatably connected to one side of the inner wall of the fixed circular sleeve 601. The rotating circular block 604 is fixedly connected to a square latch 605 at the center of one side close to the integrated square groove seat 602. The outer wall of the rotating circular block 604 is fixedly connected to an extension rod 607. The outer wall of the extension rod 607 is rotatably connected to an adjusting block 60 8. A return spring 603 is arranged between the integrated square groove seat 602 and the rotating round block 604. A rotation limit block 606 is fixedly connected to the other side of the outer wall of the fixed round sleeve 601, and the fixed round sleeve 601 is provided with a slot corresponding to the rotation limit block 606. After the initial fixation is completed, the adjusting block 608 is rotated to pull the entire rotating round block 604 to move outward, and the return spring 603 is stretched. At the same time, the rotation limit block 606 is pulled out of the groove. The rotation adjusting block 608 is placed horizontally to limit the position of the rotating round block 604 after it is pulled out, so as to avoid The round block 604 is rotated to reset under the action of the reset spring 603, and then the extension rod 607 is used to drive the rotating round block 604 to rotate, and then the square latch 605 is engaged inside the integrated square groove seat 602 to drive the integrated square groove seat 602 and the connecting shaft 502 fixedly connected thereto to rotate, thereby releasing the auxiliary protection structure 4 and the bottom bracket mechanism 3, and driving the rotating round block 604 to rotate in the reverse direction when the overall protection device is subsequently disassembled, thereby driving the two first winding wheels 503 and the two second winding wheels 504 to rotate. The connecting steel wire 7 is wound up until it is completely wound up, and the rotating adjustment block 608 is in a vertical state. Under the action of the reset spring 603, the rotating ball 604 retracts, and the rotating limit block 606 is inserted into the slot to limit the rotation of the rotating ball 604, thereby limiting the rotation of the connecting shaft 502, thereby preventing the connecting shaft 502 from rotating and causing the bottom bracket mechanism 3 and the auxiliary protection structure 4 to deflect. The storage drive mechanism 5 is respectively provided with connecting steel wires 7 on both sides of the auxiliary protection structure 4 and one end of the two bottom bracket mechanisms 3.

[0053] The working principle of this embodiment is as follows: when in use, two of the protective devices are spliced ​​together, and the first connecting hole plates 103 and the second connecting hole plates 104 at different heights on both sides of the guardrail support frame 101 are overlapped with each other, and fixed by bolts through the corresponding through holes, and the entire device is fixed to the edge of the cantilever platform and spliced. After the initial fixation is completed, the adjustment block 608 is rotated, and the overall rotating round block 604 is pulled outward, and the reset spring 603 is stretched, and the rotating limit block 606 is pulled out of the groove at the same time, and the adjusting block 608 is rotated to be placed horizontally. To limit the position of the rotating round block 604 after it is pulled out, to prevent the rotating round block 604 from being reset under the action of the reset spring 603, and then drive the rotating round block 604 to rotate through the extension rod 607, and then the square latch 605 is engaged inside the integrated square groove seat 602 to drive the integrated square groove seat 602 and the connecting shaft 502 fixedly connected thereto to rotate, and the rotation of the connecting shaft 502 drives the two first winding wheels 503 and the two second winding wheels 504 to rotate simultaneously, and then starts to release the wound connecting wire 7;

[0054] At this time, the auxiliary protection structure 4 and the two bottom bracket mechanisms 3 begin to rotate forward and backward respectively until the connecting wire 7 is completely released. At this time, the two bottom bracket mechanisms 3 are placed horizontally to fit the platform, and the overall support connector 302 is installed on the nut seat of the platform through the fixing bolts 304. At the same time, the auxiliary protection structure 4 with the connecting wire 7 released reaches the maximum angle. At this time, the connecting wire 7 is pulled to rotate the auxiliary protection structure 4 and then the top of the sliding frame 407 is pulled until it slides to the maximum stroke. At this time, the two T-shaped limit rods 410 slide on both sides of the inner wall of the rotating frame 401 until they hit the slide slot blocking cover 403. At this time, the two iron connecting clamps 408 are rotated, and then the clamps The auxiliary protection structure 4 is closed on the corresponding fixed card shaft 405, and the iron connecting card plate 408 is adsorbed by two corresponding permanent magnet blocks 406 to prevent the overall sliding frame 407 from sliding downward, and then the connecting wire 7 is released, and the opened auxiliary protection structure 4 is rotated to the maximum angle under the limit of the length of the connecting wire 7. The extended auxiliary protection structure 4 can effectively increase the range of the edge protection device and reduce the safety hazard of objects falling from high altitude. When the auxiliary protection structure 4 is hit by an object, the impact force can be transmitted to the guardrail main body mechanism 1 through the connecting wire 7 and its own structure, and then transmitted to the two bottom bracket mechanisms 3 through the connecting wire 7, thereby ensuring the stability of the overall device when facing impact;

[0055] When the overall protective device is subsequently disassembled, after removing multiple fixing bolts 304 and opening the two iron connecting clamps 408, the rotating ball block 604 is driven in reverse to rotate, thereby driving the two first winding wheels 503 and the two second winding wheels 504 to wind up the multiple connecting steel wires 7. After they are completely wound up, the rotating adjustment block 608 is in a vertical state. Under the action of the reset spring 603, the rotating ball block 604 retracts at this time, and the rotating limit block 606 is inserted into the slot to achieve rotation limitation of the rotating ball block 604, thereby achieving limitation of the connecting shaft 502, thereby preventing the connecting shaft 502 from rotating and causing the bottom bracket mechanism 3 and the auxiliary protective structure 4 to deflect.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
