Description

Technical Field

[0001] This utility model relates to the field of disassembly fixtures, and in particular to a disassembly fixture for the top plate of a through passageway. Background Technology

[0002] In the field of train manufacturing and maintenance, the passageway, as a key component connecting adjacent carriages, consists of a roof panel, side panels, steps, folding canopy, and floor panel, forming an enclosed passageway for passengers. The passageway roof panel typically uses an aluminum alloy or stainless steel frame paired with lightweight composite material panels, and the surface may be coated with fire-retardant and sound-insulating coatings, achieving lightweighting while ensuring structural strength. Its core functions encompass multiple aspects: providing structural support for the entire passageway, bearing its own weight and loads during maintenance; working closely with seals to effectively prevent the intrusion of rainwater, dust, and noise; flexibly adapting to relative displacements such as extension, retraction, and pitch between carriages during train operation through hinged or sliding structures; and ensuring that the selected materials meet stringent fire safety standards to guarantee passenger safety in emergency situations.

[0003] As a vital component of urban public transportation, the safe operation of subway cars is of paramount importance. According to maintenance requirements, the overhead slabs of subway car passageways must undergo a comprehensive condition inspection every six months, and joints must be lubricated to reduce issues such as abnormal noises from the passageways, thereby ensuring the safety and comfort of train operations.

[0004] However, under current technological conditions, disassembling the top plate of the through-passage presents numerous inconveniences. Currently, disassembling the top plate mainly relies on a two-person cooperative operation. The specific procedure is as follows: one person supports the top plate from below using simple tools or by hand, while the other person uses a workpiece to remove the bolts on the top plate. After all bolts are removed, the two people must work together to lift the top plate down. After lubrication and inspection, the top plate is then reinstalled.

[0005] However, this traditional method of operation has significant drawbacks. Due to the considerable height of the tunnel, the varying heights of the workers present considerable challenges in supporting the tunnel's roof slab. Shorter workers struggle to stably and effectively support the roof slab, increasing safety hazards during the operation. Furthermore, the two-person cooperative operation demands a high degree of coordination between the two workers; any misalignment could not only cause the tunnel roof slab to collapse and damage but also potentially result in personal injury to the workers. In addition, this method is inefficient, consuming substantial manpower and time, increasing train downtime, and disrupting the normal operation of the subway. Utility Model Content

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.

[0022] like Figures 1-4As shown, a disassembly fixture for a through-passage top plate includes a base plate 1. The top surface of the base plate 1 is provided with an auxiliary support mechanism 3, which includes a support cylinder 5, a handwheel 12, a drive gear 14, a driven gear 15, a transverse support plate 19, and an electric suction cup 24. The support cylinder 5 is fixedly connected to the top surface of the base plate 1, and the handwheel 12 is movably connected to the bottom surface of the front plate 6 of the outer wall of the support cylinder 5 through a first rotating rod 13 at the top. The drive gear 14 is fixedly connected to the first rotating rod 13, and the driven gear 15 is movably connected to the top of the support cylinder 5 through a second rotating rod 16 at the bottom and meshes with the drive gear 14. The transverse support plate 19 is movably connected to the nut 18 inside the second rotating rod 16 through a screw 20 at the bottom. The top surfaces of the longitudinal support plates 23 on both sides of the top surface of the transverse support plate 19 are respectively fixedly connected with electric suction cups 24.

[0023] like Figure 2 As shown, casters 2 are fixedly installed on the bottom surface of the base plate 1, and controller 4 is fixedly installed on the top surface of the base plate 1. A support cylinder 5 is also fixedly installed on the top surface of the base plate 1, and a rotary bearing 11 is fixedly installed at the top of the support cylinder 5. The casters 2 are fixedly installed on the bottom surface of the base plate 1, and the multi-directional flexible rotation of the casters enables convenient movement of the tooling. The controller 4 is fixedly installed on the top surface of the base plate 1, providing a control center for subsequent control of components such as the electric suction cup 24. The support cylinder 5 is fixedly installed on the top surface of the base plate 1, and a rotary bearing 11 is fixedly installed at the top of the support cylinder 5. The rotary bearing 11 provides support for the rotation of the second rotating rod 16.

[0024] like Figure 2 As shown, a front plate 6 is fixedly installed on the upper front end of the outer wall of the support cylinder 5, and a rotating hole 7 is opened on the top surface of the front plate 6 to provide an installation position and rotation space for the first rotating rod 13. A set of symmetrical side plates 8 are also fixedly installed on the upper side wall of the support cylinder 5, and an installation hole 9 is opened on the top surface of the side plate 8. A linear bearing 10 is fixedly installed in the hole of the installation hole 9. The linear bearing 10 provides guidance for the linear movement of the subsequent guide rod 22, ensuring that the transverse support plate 19 remains stable during the lifting process, preventing deviation or shaking, and improving the stability and reliability of the tooling.

[0025] like Figure 3 and Figure 4As shown, a first rotating rod 13 is fixedly installed at the top of the handwheel 12, and the first rotating rod 13 is movably installed in the rotating hole 7. A driving gear 14 is fixedly installed at the top of the first rotating rod 13, and a second rotating rod 16 is fixedly installed at the bottom of the driven gear 15. The second rotating rod 16 is inserted and fixedly installed together with the rotary bearing 11. A through hole 17 is opened at the bottom of the second rotating rod 16, penetrating the driven gear 15, and a nut 18 is fixedly installed in the hole 17. Between the driven gear 15 and the driving gear 14... The two parts are meshed together. By turning the handwheel 12, the first rotating rod 13 is driven to rotate. The first rotating rod 13 drives the driving gear 14 to rotate. When the driving gear 14 rotates, it drives the driven gear 15 to rotate through the gear meshing, which in turn drives the second rotating rod 16 to rotate in the rotary bearing 11. The bottom end of the second rotating rod 16 has a through hole 17 that passes through the driven gear 15. A nut 18 is fixedly installed in the through hole 17. The nut 18 rotates together with the second rotating rod 16, providing the power basis for the subsequent lifting and lowering movement of the screw 20.

[0026] like Figure 3 As shown, a screw 20 is fixedly installed on the bottom surface of the transverse support plate 19, and the screw 20 is threadedly connected to the nut 18. A limit plate 21 is fixedly installed at the bottom end of the screw 20. Guide rods 22 are also fixedly installed on both sides of the bottom surface of the transverse support plate 19, and the guide rods 22 are movably inserted into the linear bearing 10. When the nut 18 rotates, the screw 20 will achieve lifting and lowering movement according to the thread transmission principle. The limit plate 21 is fixedly installed at the bottom end of the screw 20 to prevent the screw 20 from coming out of the nut 18 during the lifting and lowering process. The guide rod 22 moves linearly in the linear bearing 10 to guide the transverse support plate 19 to rise and fall smoothly. The height of the transverse support plate 19 can be adjusted as needed to adapt to the top plate of the through passage at different heights.

[0027] like Figure 3 As shown, a set of symmetrical longitudinal support plates 23 are also fixedly installed on the top surface of the transverse support plate 19, and a set of symmetrical electric suction cups 24 are also fixedly installed on the top surface of the longitudinal support plate 23. The electric suction cups 24 are electrically connected to the controller 4. The controller 4 controls the suction and release actions of the electric suction cups 24. The longitudinal support plate 23 provides an installation platform for the electric suction cups 24, ensuring that the electric suction cups 24 can stably suction the top plate of the through channel. The electric suction cups 24 firmly fix the top plate of the through channel through suction, which facilitates disassembly and installation operations for operators.

[0028] The specific operating principle of this through-passage top plate disassembly tool is as follows:

[0029] When disassembling the top plate of the passageway is required, the entire tooling is first moved to a suitable position below the top plate using the casters 2 mounted on the bottom surface of the base plate 1. Once in the designated position, the operator begins to operate the auxiliary support mechanism 3 to support the top plate of the passageway. The operator turns the handwheel 12, which drives the first rotating rod 13 to rotate within the rotating hole 7 on the top surface of the front plate 6. The rotation of the first rotating rod 13 drives the driving gear 14 to rotate synchronously. When the driving gear 14 rotates, the driven gear 15 meshes with it, driving the driven gear 15 to rotate. Furthermore, because the second rotating rod 16 at the bottom of the driven gear 15 is fixedly installed with the rotary bearing 11 at the top of the support cylinder 5, the driven gear 15 and the second rotating rod 16 can rotate within the rotary bearing 11. The second rotating rod 16 will drive the nut 18, which is fixedly installed in the through hole 17 at the bottom, to rotate synchronously. When the nut 18 rotates, the screw 20 installed on the bottom surface of the transverse support plate 19 is threadedly connected to the nut 18. According to the principle of thread transmission, when the nut 18 rotates in the fixed position, the screw 20 will achieve lifting and lowering motion. In order to ensure that the transverse support plate 19 remains stable during lifting and lowering and to prevent deviation or shaking, the guide rods 22 installed on both sides of the bottom surface of the transverse support plate 19 will move linearly in the linear bearing 10 opened on the top surface of the side plate 8, guiding the transverse support plate 19 to lift and lower smoothly. The limiting plate 21 installed at the bottom end of the screw 20 is used to prevent the screw from moving. During the lifting process, rod 20 disengages from nut 18. By continuously rotating handwheel 12, the height of transverse support plate 19 is adjusted to a suitable position, allowing the electric suction cups 24 mounted on the top surfaces of longitudinal support plates 23 on both sides of the transverse support plate 19 to contact the top plate of the passageway. The operator activates the electric suction cups 24 via controller 4, generating suction force to firmly hold the top plate of the passageway in place. At this point, the operator can begin removing the bolts from the top plate of the passageway. Because the top plate of the passageway is stably held in place by the electric suction cups 24, no double-person support is required, avoiding situations where the top plate falls and is damaged due to miscoordination or personal injury to the operators. Once all bolts are removed... After disassembly, the operator can continue to fine-tune the height of the transverse support plate 19 using the handwheel 12 to ensure that the top plate of the through passage is placed stably on the electric suction cup 24. Then, carefully move the tooling together with the top plate of the through passage out of the work area for subsequent lubrication and maintenance. After the maintenance is completed, move the tooling back to the installation position of the top plate of the through passage, and control the electric suction cup 24 to adsorb the top plate of the through passage again using the controller 4. Then, adjust the height of the transverse support plate 19 using the handwheel 12 to align the top plate of the through passage with the installation position, making it convenient for the operator to perform the installation operation. After installation, control the electric suction cup 24 to release the top plate of the through passage using the controller 4 to complete the disassembly and installation of the entire top plate of the through passage.Throughout the process, the tool is small in size, making it easy to move and operate within the carriage. It can be operated by a single person, which greatly improves work efficiency, reduces manpower input and train downtime, and ensures the normal operation of the subway.
