DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] In electric locomotives and rail transit systems, pantographs are key current-collecting devices, and their safety and reliability are crucial to the normal operation of electric locomotives. The safety valve in the pantograph is an important safety protection component, which is used to limit the wind pressure entering the pantograph airbag and ensure that the pantograph airbag works within the normal working wind pressure. In order to ensure the safety and stability of train travel, the safety valve needs to be regularly inspected and replaced.

[0040] In the prior art, the safety valve includes an adjusting screw sleeve, a spring arranged in the adjusting screw sleeve, a spring seat inserted on the spring, and a fixed pin located in the spring seat. When the spring needs to be replaced due to aging or failure, the fixed pin cannot be removed from the spring seat due to the lack of disassembly tooling, so that the spring cannot be separated from the spring seat to remove the spring from the safety valve. Therefore, the whole valve is usually replaced. However, the replacement of the whole safety valve makes the maintenance cost high and causes a waste of resources.

[0041] In view of this, the safety valve disassembly tool provided in the present application is provided with a driving assembly, the driving assembly includes a stand and a driving member, and then a support assembly is connected to the stand, and the adjusting screw sleeve is supported by the supporting force of the support assembly. A pressing member is connected to the driving member, and the pressing member has a first accommodating chamber and an entrance, so that the spring seat can enter the first accommodating chamber through the entrance. A pressing portion is provided in the first accommodating chamber, and when the driving member drives the pressing member to move toward the supporting assembly, as the pressing member moves, the pressing portion contacts the spring seat and presses the spring seat, so that the spring is compressed, and the fixed pin shaft located in the spring seat gradually emerges from the spring seat, so that the operator can take out the fixed pin shaft through the outlet of the pressing member, and then disassemble the spring seat and the spring, so that when the spring needs to be replaced, the safety valve can be disassembled and the spring can be replaced, without the need to replace the entire valve, thereby reducing the maintenance cost and avoiding the waste of resources.

[0042] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Figure 1 A schematic diagram of the structure of the safety valve disassembly tool provided in an embodiment of the present application; Figure 2 for Figure 1 A schematic diagram of the structure of the middle pressing member; Figure 3 for Figure 1 Structural schematic diagram of the middle support plate; Figure 4 for Figure 1 A schematic structural diagram of the second supporting portion; Figure 5 A schematic diagram of the structure of a second fixing member provided in an embodiment of the present application; Figure 6 A schematic diagram of a portion of the structure of a safety valve provided in an embodiment of the present application; Figure 7 for Figure 6 Schematic diagram of the decomposition.

[0044] See also Figures 1 to 7The present application provides a safety valve disassembly tool, the safety valve includes an adjusting screw sleeve 110, a spring 120 located in the adjusting screw sleeve 110 and a handle rod 130 passing through the spring 120, a spring seat 140 is inserted on the spring 120, and the end of the handle rod 130 away from the spring seat 140 is fixedly connected to a handle 150, and the handle 150 is located outside the adjusting screw sleeve 110, and the end of the handle rod 130 passing through the spring seat 140 is inserted with a fixing pin 160, and the fixing pin 160 is located in the spring seat 140, and the fixing pin 160 is used to fix the spring 120 between the adjusting screw sleeve 110 and the spring seat 140; the safety valve disassembly tool includes a drive assembly 200, a support assembly 300 and a pressing member 400, and the drive assembly 200 includes a stand 210 and A driving member 220 is installed on the stand 210, and a supporting assembly 300 is connected to the stand 210, and the supporting assembly 300 is used to support the adjusting screw sleeve 110; the driving member 220 is connected to a pressing member 400, and the pressing member 400 has a first accommodating chamber 410 and a pressing portion 420 located in the first accommodating chamber 410, and an inlet 430 and an outlet 440 connected to the first accommodating chamber 410 are opened on the pressing member 400, and the inlet 430 is used for the spring seat 140 to enter the first accommodating chamber 410; the pressing member 400 is configured to move toward the supporting assembly 300 under the drive of the driving member 220, and the pressing portion 420 contacts the spring seat 140 and presses the spring seat 140 so that the fixing pin 160 is exposed from the spring seat 140 to the outlet 440.

[0045] It should be noted that the safety valve also includes a valve body. Before disassembling the spring 120, the adjusting screw sleeve 110 is first loosened and removed from the valve body. As a result, the spring 120, the handle rod 130, the spring seat 140, the handle 150 and the fixing pin 160 are also separated from the valve body along with the adjusting screw sleeve 110.

[0046] Exemplarily, the stand 210 serves as a basic structure of the safety valve disassembly tooling, and the stand 210 provides a stable support platform, so that the support assembly 300 can be stably placed on the stand 210 .

[0047] Furthermore, by providing the support assembly 300, the adjusting screw sleeve 110 can be stably placed on the safety valve disassembly tool to prevent damage to other components in the adjusting screw sleeve 110 due to shaking during the disassembly process. At the same time, the support assembly 300 is correspondingly provided with the pressing member 400, providing an accurate positioning reference for the pressing member 400, ensuring that the pressing portion 420 can accurately contact the spring seat 140.

[0048] In a specific implementation, in order to drive the movement of the pressing member 400, a driving member 220 is provided on the stand 210, and the driving member 220 is connected to the pressing member 400. The driving member 220 provides a stable driving force to the pressing member 400, and the driving member 220 can ensure that the pressing member 400 moves toward the supporting assembly 300. The driving member 220 drives the pressing member 400 to move, which not only improves the disassembly efficiency, but also reduces the work intensity of the operator.

[0049] The driving member 220 may be a hydraulic cylinder or an electric cylinder. The hydraulic cylinder has the advantages of large thrust and good stability, while the electric cylinder is a common automated driving element that can provide precise position and speed control. The driving member 220 may also be other structures that drive the pressing member 400 to move toward the supporting assembly 300, which is not limited in this embodiment. In addition, the stand 210 is also provided with a control button or a manual driving structure (such as a hand crank) for driving the driving member 220 to drive the pressing member 400 to move.

[0050] In some embodiments, the pressing member 400 has a first accommodating cavity 410, so that the spring seat 140 can enter the pressing member 400. The pressing portion 420 provided on the inner side wall of the first accommodating cavity 410 is a component directly in contact with the spring seat 140, that is, the pressing member 400 moves toward the supporting assembly 300 under the drive of the driving member 220, and the spring seat 140 enters the first accommodating cavity 410 through the inlet 430 on the pressing member 400, and the pressing member 400 continues to move toward the spring seat 140 under the drive of the driving member 220, so that the pressing portion 420 contacts the spring seat 140, and presses the spring seat 140 under the drive of the driving member 220, so that the spring 120 sleeved on the spring seat 140 is compressed along the length direction of the handle rod 130, thereby, the fixing pin 160 inserted on the handle rod 130 is gradually exposed from the spring seat 140, and the operator can take out the fixing pin 160 through the outlet 440.

[0051] It can be understood that the first accommodating cavity 410 provides sufficient space for the pressing portion 420 to press the spring seat 140 evenly and stably, thereby improving the disassembly accuracy.

[0052] The pressing portion 420 may be in the shape of a ring disposed along the inner wall of the first accommodating cavity 410, and has a certain contact plane on the side facing the spring seat 140 so as to contact and press the spring seat 140, and the pressing portion 420 is usually made of a material with a relatively high strength to ensure that the pressing portion 420 can provide sufficient pressing force to compress the spring 120. The shape and material of the pressing portion 420 may be set according to actual needs, and this embodiment is not limited thereto.

[0053] During use, first, the adjusting screw sleeve 110 is loosened and removed from the valve body, and the spring 120, the handle rod 130, the spring seat 140, the handle 150 and the fixed pin 160 are separated from the valve body along with the adjusting screw sleeve 110, and the adjusting screw sleeve 110 is placed on the support assembly 300 to ensure the stability of the adjusting screw sleeve 110, and at the same time ensure that the inlet 430 of the pressing member 400 is aligned with the spring seat 140, so that the spring seat 140 enters the first accommodating chamber 410. Then the driving member 220 is started, and under the drive of the driving member 220, the pressing member 400 begins to move toward the support assembly 300, and the pressing portion 420 contacts the spring seat 140 and gradually applies pressure to the spring seat 140. As the spring 120 is compressed, the fixed pin 160 begins to gradually emerge from the spring seat 140 until it is completely exposed to the outlet 440. When the fixing pin 160 is completely exposed, the fixing pin 160 can be taken out manually or with a tool. After the fixing pin 160 is taken out, the driving member 220 drives the pressing member 400 to move away from the spring seat 140, so that the spring seat 140 is separated from the first accommodating cavity 410 and has a certain distance from the pressing member 400, which is convenient for the operator to remove the spring seat 140, and then remove the spring 120 from the handle rod 130 for inspection and replacement. Therefore, when the spring 120 needs to be replaced, the safety valve can be disassembled and the spring 120 can be replaced without replacing the entire valve, thereby reducing the inspection cost and avoiding waste of resources.

[0054] See also Figure 2 In the embodiment of the present application, the inlet 430 is located on the end surface of the pressing member 400 facing the supporting assembly 300, and the outlet 440 is located on the side of the pressing member 400; the pressing portion 420 is arranged on the inner wall periphery of the first accommodating cavity 410, and is located at one end of the first accommodating cavity 410 close to the inlet 430.

[0055] In a specific implementation, the inlet 430 is located at the end surface of the pressing member 400, so that the spring seat 140 can directly and quickly enter the first accommodating cavity 410 through the inlet 430 without a complicated alignment process, thereby simplifying the operation steps and improving the disassembly efficiency.

[0056] It should be noted that the outlet 440 is located on the side of the pressing member 400. In the process that the pressing portion 420 contacts the spring seat 140 and gradually applies pressure to the spring seat 140, as the spring 120 is compressed, the fixing pin 160 gradually emerges from the spring seat 140 until it is completely exposed to the outlet 440 on the side of the pressing member 400. This design allows the operator to easily observe and remove the fixing pin 160, further enhancing the convenience of operation.

[0057] Among them, the pressing part 420 is arranged on the inner wall of the first accommodating chamber 410, which can ensure that the pressing part 420 can evenly and stably apply pressure to the spring seat 140 during the pressing process. In this way, the disassembly accuracy is improved and potential damage to other parts of the safety valve is avoided. Through the reasonable layout of the inlet 430, the outlet 440 and the pressing part 420, the safety valve disassembly tool provided by the present application can make full use of the space during operation, reduce interference and obstruction during operation, and make the entire disassembly process smoother and more efficient.

[0058] See also Figure 2 In the embodiment of the present application, a limiting sleeve 500 is provided at one end of the pressing member 400 facing the supporting assembly 300, and the limiting sleeve 500 is connected to the first accommodating chamber 410 through the inlet 430. The limiting sleeve 500 is used for allowing the spring seat 140 to enter the first accommodating chamber 410 along the inner cavity of the limiting sleeve 500 through the inlet 430.

[0059] It should be noted that the limiting sleeve 500 provides a precise guide path for the spring seat 140, ensuring that the spring seat 140 can accurately enter the first accommodating cavity 410 along the inner cavity of the limiting sleeve 500. This not only improves the accuracy of disassembly, but also avoids unnecessary damage to the spring seat 140 or other components during operation.

[0060] Furthermore, the design of the limiting sleeve 500 enhances the stability during the disassembly process. When the spring seat 140 is pushed into the first accommodating chamber 410, the limiting sleeve 500 can ensure that the spring seat 140 maintains the correct position and posture, thereby improving the reliability of the disassembly and the work efficiency.

[0061] See also Figure 1 and Figure 2 In the embodiment of the present application, the driving member 220 has a first connecting portion 221 , and the pressing member 400 is provided with a second connecting portion 450 at one end facing the driving member 220 , and the second connecting portion 450 is connected to the first connecting portion 221 .

[0062] In some embodiments, the design of the first connection part 221 and the second connection part 450 ensures a stable connection between the driving member 220 and the pressing member 400. At the same time, the assembly and disassembly process between the driving member 220 and the pressing member 400 becomes simple and quick. The operator only needs to align and connect the first connection part 221 and the second connection part 450, without complicated adjustment or calibration steps, which improves work efficiency.

[0063] See also Figure 1 and Figure 2In the embodiment of the present application, a first fixing member 600 is also included, one of the first connecting portion 221 and the second connecting portion 450 is an insertion rod, and the other is a slot matching the insertion rod; a socket is provided on the slot, and the first fixing member 600 abuts against the insertion rod through the socket to fix the insertion rod and the slot.

[0064] In specific implementation, the connection between the driving member 220 and the pressing member 400 becomes fast and firm through the insertion rod and the slot. When the insertion rod is inserted into the slot, the first fixing member 600 cooperates with the jack to quickly achieve fixed connection between the insertion rod and the slot, greatly improving assembly efficiency.

[0065] The first fixing member 600 is in contact with the insertion rod through the insertion hole, ensuring a tight connection between the insertion rod and the slot. Such a design can effectively prevent accidents caused by loose connection or falling off of the pressing member 400 during use, thereby improving the reliability and safety of the disassembly work.

[0066] It should be noted that the first fixing member 600 can be a bolt structure, and the insertion hole on the slot is set as a threaded hole matching the bolt. By rotating the first fixing member 600 until the first fixing member 600 abuts against the insertion rod, the driving member 220 and the pressing member 400 are fixedly connected. With such a design, the structure is relatively simple and easy to use, and has high reliability. The first fixing member 600 can also be other structures that can ensure a firm connection between the insertion rod and the slot, and this embodiment is not limited here.

[0067] In a specific implementation, the first connecting part 221 can be an insertion rod, and the second connecting part 450 can be a slot matching the insertion rod, or the first connecting part 221 can be a slot, and the second connecting part 450 can be an insertion rod. The purpose is to achieve a stable connection between the driving member 220 and the pressing member 400. This embodiment is not limited here.

[0068] See also Figure 1 and Figure 3 In the embodiment of the present application, the support assembly 300 includes a support platform 310, a support seat 320 and a support plate 330 connected to the support seat 320. The support platform 310 is located on the stand 210 to support the support seat 320; a second accommodating cavity 340 is formed between the support seat 320 and the support plate 330, and the second accommodating cavity 340 is used to accommodate the handle 150; the support plate 330 has a mounting portion 331, and the handle rod 130 is connected to the support plate 330 via the mounting portion 331, so that the support plate 330 supports the adjusting screw sleeve 110.

[0069] Among them, by the support platform 310 being located on the stand 210 , the support seat 320 is firmly supported, thereby enhancing the stability of the entire support assembly 300 .

[0070] Exemplarily, the stand 210 may be provided with at least two beams, the support platform 310 is a plate-like structure, and at least two placement grooves are provided on a side of the support platform 310 facing the beams, and the placement grooves and the beams are connected one by one, thereby making the support platform 310 firmly connected to the stand 210.

[0071] It should be noted that the second accommodating cavity 340 formed between the support seat 320 and the support plate 330 provides a storage space for the handle 150. With such a design, when the driving member 220 drives the pressing member 400 to press the spring seat 140, the support plate 330 provides a supporting force for the adjusting screw sleeve 110, ensuring that the adjusting screw sleeve 110 can remain stable when subjected to a torque, and at the same time, the handle 150 located in the second accommodating cavity 340 can be prevented from being squeezed, so as to prevent the driving force of the driving member 220 from damaging the handle 150.

[0072] In some embodiments, in order to achieve the stable placement of the adjusting screw sleeve 110 on the support plate 330, and the handle 150 is located in the second accommodating cavity 340 formed between the support seat 320 and the support plate 330, the support plate 330 has a mounting portion 331, and the handle rod 130 is connected to the support plate 330 via the mounting portion 331, and the adjusting screw sleeve 110 and the handle 150 are respectively located on two opposite sides of the support plate 330.

[0073] See also Figure 3 In the embodiment of the present application, the mounting portion 331 is a snap-in groove provided on the support plate 330 , one end of the snap-in groove is connected to the side of the support plate 330 , and the snap-in groove is used to connect the support plate 330 with the handle bar 130 .

[0074] In specific implementation, the mounting portion 331 is a clamping groove, which can be set to a long strip shape, and one end of the clamping groove is connected to the side of the support plate 330 to form an open notch, and the handle rod 130 is aligned with the open notch of the clamping groove, and then the handle rod 130 is pushed in along the notch direction, thereby making the bottom surface of the adjusting screw sleeve 110 fit with the support plate 330, so that the support plate 330 can support the adjusting screw sleeve 110. Such a design ensures the stability of the adjusting screw sleeve 110, and at the same time, the open design of the clamping groove makes the connection between the handle rod 130 and the support plate 330 simple and quick, without the need for installation tools.

[0075] See also Figure 3 , Figure 6 and Figure 7 In the embodiment of the present application, the width of the snap-in groove matches the diameter of the handle rod 130 .

[0076] It should be noted that the diameter of the handle rod 130 refers to the cross-sectional diameter of the handle rod 130, and the width of the snap-in groove is set to a size that matches the cross-sectional diameter of the handle rod 130. Thus, when the handle rod 130 enters the snap-in groove along the notch of the snap-in groove, the inner wall of the snap-in groove contacts the outer wall of the handle rod 130. The handle rod 130 can smoothly enter the snap-in groove while preventing the handle rod 130 from shaking during the disassembly process, thereby improving stability.

[0077] See also Figure 1 and Figure 4 In the embodiment of the present application, the support seat 320 includes a first support portion 321 and two second support portions 322 , the two second support portions 322 are spaced apart on the first support portion 321 , and one end of the two second support portions 322 away from the first support portion 321 is connected to the support plate 330 .

[0078] It can be understood that the first support portion 321 is the main load-bearing part of the support base 320 and can be designed as a plate-like structure so as to better fit with the support platform 310, increase the contact area, and improve stability.

[0079] In some embodiments, the two second support portions 322 are symmetrically arranged on the first support portion 321, and one end away from the first support portion 321 is connected to the support plate 330 to support the support plate 330. A second accommodating cavity 340 is formed between the first support portion 321, the two second support portions 322 and the support plate 330.

[0080] Furthermore, in order to increase stability and strength, the second support portion 322 may be configured as a reinforcing rib or a reinforcing plate to form a stable connection with the first support portion 321 and the support plate 330 .

[0081] The first support portion 321 and the second support portion 322 may be provided as an integrally formed part, or may be firmly connected by welding, which is not limited in this embodiment.

[0082] See also Figures 3 to 5 In the embodiment of the present application, at least two second fixing members 700 are further included. At least two first connection holes 332 are opened on the support plate 330, and each first connection hole 332 is evenly distributed on both sides of the clamping groove; at least one second connection hole 3221 is provided on the second support portion 322, and the first connection hole 332 and the second connection hole 3221 are arranged in a one-to-one correspondence. Each second fixing member 700 passes through the corresponding first connection hole 332 and the second connection hole 3221 in sequence to fix the support plate 330 to the second support portion 322.

[0083] The support plate 330 is fixedly connected to the second support portion 322 by using at least two second fixing members 700, thereby ensuring a more stable and reliable connection between the support plate 330 and the second support portion 322. This multi-point fixing method effectively prevents the support plate 330 from loosening due to vibration or external force, thereby enhancing the structural stability of the entire support assembly 300.

[0084] It should be noted that the first connection holes 332 are evenly distributed on both sides of the clamping groove, so that the support plate 330 can achieve uniform stress distribution when subjected to force, and improve the connection stability between the support plate 330 and the second support portion 322.

[0085] Exemplarily, the second fixing member 700 may be a pin, one end of which has a head, and the other end of which may pass through the first connection hole 332 and the second connection hole 3221 in sequence, so that the support plate 330 is fixedly connected to the second support portion 322. Alternatively, the second fixing member 700 may be a bolt, and the first connection hole 332 and the second connection hole 3221 are threaded holes matching the bolts, so that the bolts are threadedly connected to the threaded holes, thereby making the support plate 330 and the second support portion 322 firmly connected. The second fixing member 700 may also be other structures that can realize a firmly connected support plate 330 and the second support portion 322, and this embodiment is not limited here.

[0086] In summary, the safety valve disassembly tool provided in the present application is provided with a driving assembly 200, the driving assembly 200 includes a stand 210 and a driving member 220, and then a supporting assembly 300 is connected to the stand 210, and the adjusting screw sleeve 110 is supported by the supporting force of the supporting assembly 300. A pressing member 400 is connected to the driving member 220, and the pressing member 400 has a first accommodating chamber 410 and an inlet 430, so that the spring seat 140 can enter the first accommodating chamber 410 through the inlet 430. A pressing portion 420 is provided in the first accommodating chamber 410. When the driving member 220 drives the pressing member 400 to move toward the supporting assembly 300, as the pressing member 400 moves, the pressing portion 420 contacts the spring seat 140 and presses the spring seat 140, so that the spring 120 is compressed, and the fixing pin 160 located in the spring seat 140 is gradually exposed from the spring seat 140, so that the operator can take out the fixing pin 160 through the outlet 440 of the pressing member 400, and then disassemble the spring seat 140 and the spring 120. Therefore, when the spring 120 needs to be replaced, the safety valve can be disassembled and the spring 120 can be replaced without replacing the entire valve, thereby reducing the maintenance cost and avoiding waste of resources.
