Description

Technical Field

[0001] This utility model belongs to the field of testing technology, specifically relating to an indoor maintenance and inspection device for sliding hydraulic cylinders. Background Technology

[0002] The TDY203 piston rod is a crucial component of the reduction gear jack. Currently, during the assembly process, the only way to check for misalignment of the TDY203 piston rod and its pressure valve body is by visual inspection or comparison with a ruler. However, this method cannot detect even slight misalignments of the TDY203 piston rod or the pressure valve body. Currently, the installation of the TDY203 piston rod is only completed after the sliding cylinder is formed and inserted into the housing for verification. If misalignment is discovered at this point, the TDY203 piston rod must be removed again, wasting time and increasing workload. Therefore, it is impossible to effectively check for misalignment of the TDY203 piston rod before installation.

[0003] Meanwhile, the severity of the flash on the sliding cylinder body affects whether the deceleration jack can be inserted into the housing. Severe flash can prevent the deceleration jack from being fully inserted into the housing. During indoor maintenance of the deceleration jack, some sliding cylinder bodies with less wear are reused. However, the wear level of the sliding cylinder body cannot be effectively verified. Therefore, it's impossible to determine whether the reassembled sliding cylinder body can be inserted into the housing. Furthermore, the TDY203 deceleration jack sliding cylinder assembly weighs 3.4 kg, and the housing assembly weighs 4.6 kg, totaling 8 kg when assembled. This is difficult for one person to operate, and there is a risk of injury when installing the TDY203 piston rod onto the sliding cylinder and then assembling it onto the housing. Utility Model Content

[0004] To address the problems in existing technologies that cannot effectively check for misalignment of the TDY203 piston rod before installation and for flash on the sliding cylinder body, this invention provides an indoor maintenance and inspection device for sliding cylinders.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A sliding cylinder indoor maintenance and inspection device includes a piston rod offset inspection mechanism and a sliding cylinder flash detection mechanism;

[0007] The piston rod offset inspection mechanism includes a first cylinder for simulating a sliding cylinder and a second cylinder for simulating a housing. The first cylinder has a first chamber for accommodating the piston head of the piston rod and a through groove communicating with the first chamber. The shape and size of the through groove match the shape and size of the piston rod. The second cylinder has a second chamber for accommodating the first cylinder and a groove communicating with the second chamber. The shape and size of the groove match the shape and size of the end of the piston rod.

[0008] By adopting this technical solution, the present invention provides a first cylinder that simulates a sliding cylinder and a second cylinder that simulates a housing. By installing the piston rod into the first cylinder and then installing the first cylinder with the piston rod into the second cylinder, the process of installing the sliding cylinder into the housing is simulated. If the piston rod has no offset side, its end can be inserted into the groove that matches its shape. If the piston rod has an offset side, its end cannot be inserted into the groove that matches its shape. In this way, it is possible to intuitively determine whether the piston rod is offset.

[0009] Preferably, the outer wall of the second cylinder is also provided with a handle.

[0010] With this technical solution, the first cylinder can be easily installed into the second cylinder using a handle, making it simple and easy to operate.

[0011] Preferably, the height of the first cylinder is greater than the height of the second chamber.

[0012] After adopting this technical solution, the height of the first cylinder is greater than the height of the second chamber, which is consistent with the actual height and facilitates the assembly and disassembly of the first and second cylinders.

[0013] Preferably, the inner diameter and height of the through groove are the same as the inner diameter and height of the through hole on the deceleration top sealing cover.

[0014] After adopting this technical solution, the first cylinder more realistically simulates a sliding oil cylinder. After the piston rod is inserted into the through groove, it can fully fit with the through groove, and it can also determine whether the piston rod is tilted.

[0015] Preferably, the groove includes a base embedded in the bottom wall of the first cylinder, and the base is provided with a groove, the size and shape of which match the size and shape of the end of the piston rod away from the piston head.

[0016] After adopting this technical solution, the shape of the groove is the same as the groove structure inside the actual shell. The size and shape of the groove match the size and shape of the end of the piston rod away from the piston head, so that the end of the piston rod away from the piston head can be inserted into the groove, thereby realizing tilt detection.

[0017] Preferably, when the first cylinder is located inside the second cylinder, the first chamber, the through groove, the second chamber, and the groove are arranged sequentially from top to bottom, and the central axes of the first chamber, the through groove, the second chamber, and the groove overlap.

[0018] Preferably, the sliding cylinder flash detection mechanism includes a third cylinder, which has a third chamber for accommodating the cylinder body. The third chamber has a primary boss, a secondary boss, and a tertiary boss arranged from one side of the opening. The primary boss, the secondary boss, and the tertiary boss are all annular structures, and the inner diameters of the primary boss, the secondary boss, and the tertiary boss decrease sequentially. The inner diameter of the tertiary boss matches the outer diameter of the cylinder body.

[0019] Preferably, the outer wall of the third cylinder is provided with a handle.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] 1. This utility model can effectively check for misalignment before installing the TDY203 piston rod. If the TDY203 piston rod is found to be misaligned, it will not be installed into the sliding cylinder, saving time and reducing workload. It also eliminates problematic TDY203 piston rods, effectively improving work efficiency.

[0022] 2. This utility model allows the sliding cylinder body to be inserted into the middle of the inspector. If the burrs are severe, it will be impossible to insert. The sliding cylinder body that cannot be inserted will not be installed. If the sliding cylinder body can be inserted into the middle of the inspector, indoor maintenance work can continue, which effectively improves work efficiency. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] The following is combined Figures 1-5 This utility model will be described in detail.

[0033] like Figure 1 and Figure 2 As shown, a sliding cylinder chamber maintenance and inspection device includes a first cylinder for simulating a sliding cylinder and a second cylinder for simulating a housing. The first cylinder has a first chamber 1 for accommodating the piston head of a piston rod 6. A through groove 2 communicating with the first chamber 1 is provided in the first cylinder. The shape and size of the through groove 2 match the shape and size of the piston rod 6. The second cylinder has a second chamber 3 for accommodating the first cylinder. A groove 5 communicating with the second chamber 3 is provided on the second cylinder. The shape and size of the groove 5 match the shape and size of the end of the piston rod 6 (see the structural diagram of the TDY203 piston rod). Figure 3(As shown). In this embodiment, the sliding cylinder internal maintenance and inspection device is made of resin material using 3D printing technology. In other embodiments, the sliding cylinder internal maintenance and inspection device can also be made using conventional mold casting methods; it should be noted that the raw materials used are commercially available materials and there is no improvement.

[0034] Specifically, the first cylinder is cylindrical with a diameter of 60mm. The first chamber 1, with an opening at the top, is also cylindrical with a diameter of 56mm, a height of 100mm, and a wall thickness of 2mm. The bottom wall thickness of the first cylinder is 30mm. The second cylinder is cylindrical with a diameter of 66mm. The second chamber 3, with an opening at the top, is also cylindrical with a diameter of 61mm, a height of 70mm, and a wall thickness of 2.5mm. The bottom wall thickness of the second cylinder is 5mm. A groove 5 is provided on this bottom wall, extending through the thickness of the second cylinder's bottom wall. The through groove 2 is cylindrical.

[0035] When using this inspector, the piston is first installed into the first cylinder, and the piston rod 6 is passed through the through groove 2 so that the head of the piston rod 6 is located in the first chamber 1, simulating the state when the piston is installed in the sliding cylinder. Then, the first cylinder with the piston rod 6 installed is placed into the second cylinder to simulate the process of installing the sliding cylinder into the housing. During this process, it is observed whether the lower end of the piston rod 6 can be inserted into the groove 5. If it can be inserted into the groove 5, the piston rod 6 is not offset from the lower end. If it cannot be inserted into the groove 5, it indicates that there is an offset. This achieves the offset detection of the piston rod 6.

[0036] In one embodiment, a handle 4 is also provided on the outer wall of the second cylinder. The handle 4 can be gripped when installing or removing the first cylinder into the second cylinder, making operation more convenient. In this embodiment, the handle 4 has a height of 52 mm and a width of 29.26 mm (distance from one side connected to the first cylinder to the other).

[0037] In one embodiment, the height of the first cylinder is greater than the height of the second chamber 3. Specifically, the height of the first cylinder is 100mm, and the height of the second cylinder is 70mm; this arrangement facilitates the installation and disassembly of the first and second cylinders.

[0038] In one embodiment, the inner diameter and height of the through groove 2 are consistent with the inner diameter and height of the through hole on the deceleration top sealing cover. Specifically, the inner diameter of the through groove 2 is 22.2 mm and the height is 30 mm, in order to more realistically simulate a sliding cylinder.

[0039] In one embodiment, the groove 5 includes a base 501 embedded in the bottom wall of the first cylinder, and a groove 502 is provided on the base 501. The size and shape of the groove 502 match the size and shape of the end of the piston rod 6 away from the piston head. Specifically, both the base 501 and the groove 502 are cylindrical structures, with the base 501 having a diameter of 30mm and a height of 3mm, and the groove 502 having a diameter of 11.18mm and a height of 5mm. Figure 2 and Figure 3 As shown, the size of the groove 502 is just enough to accommodate the end of the piston rod 6. Therefore, it can be determined whether there is any offset by whether the end of the piston rod 6 can be inserted into the groove 502.

[0040] In one embodiment, when the first cylinder is located inside the second cylinder, the first chamber 1, the through groove 2, the second chamber 3, and the groove 5 are arranged sequentially from top to bottom, and the central axes of the first chamber 1, the through groove 2, the second chamber 3, and the groove 5 overlap, so as to ensure the accuracy of the offset detection.

[0041] In one embodiment, such as Figure 4-5 As shown, the sliding cylinder flash detection mechanism includes a third cylinder 7, which contains a third chamber capable of accommodating the cylinder body 12. Within the third chamber, from one side of the opening, are a primary boss 8, a secondary boss 9, and a tertiary boss 10. All three bosses are annular structures, with their inner diameters decreasing sequentially. The inner diameter of the tertiary boss 10 matches the outer diameter of the cylinder body 12. In this embodiment, the outer diameter of the third cylinder 7 is 88.6 mm, its height is 151 mm, the inner radius of the tertiary boss 10 is 36.49 mm, the inner radius of the secondary boss 9 is 36.5 mm, and the inner radius of the primary boss 8 is 39.3 mm. The cylinder body 12 can be inserted into the cavity of the tertiary boss 10. If the flash is severe, it cannot be inserted, and cylinder bodies 12 that cannot be inserted will not be installed.

[0042] In one embodiment, a handle 11 is provided on the outer wall of the third cylinder 7. The total width of the third cylinder 7 plus the handle 11 is 146.08 mm.

[0043] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
