Description

Technical Field

[0001] This utility model relates to the field of switchgear, and in particular to the assembly equipment for blades of explosion-proof membranes used in gas-insulated switchgear. Background Technology

[0002] Gas-insulated switchgear (GIS) is a crucial component of power systems, performing opening, closing, control, and protection during power generation, transmission, distribution, and energy conversion. GIS contains a gas chamber filled with gas. In the event of a fault, the gas pressure within the chamber increases. Therefore, GIS is equipped with an explosion-proof membrane. When the gas pressure reaches a certain level, the membrane ruptures, releasing the gas and preventing the switchgear from exploding.

[0003] To ensure the explosion-proof membrane can burst smoothly, sharp objects are usually placed around the membrane to puncture it. For example... Figure 6 As shown, the sharp object comprises two intersecting blades, a first blade 11 and a second blade 12, assembled together. In practical applications, the two blades need to be assembled first before being installed to form an explosion-proof membrane. However, the existing method of manually assembling the two blades easily cuts workers; therefore, how to assemble these two intersecting blades has become an urgent problem to be solved. Utility Model Content

[0004] In view of this, the present invention proposes an assembly device for the blade of an explosion-proof membrane in a gas-insulated switchgear, comprising:

[0005] The base has a first slit that allows a first blade to pass through;

[0006] A first pushing device is used to push a first blade into and partially protrude from the first gap;

[0007] The assembly is capable of accommodating a second blade, the assembly being movably inserted into the base, and the assembly being capable of pushing the second blade to assemble with the portion of the first blade extending out of the first gap.

[0008] According to the assembly equipment for the blades of the explosion-proof membrane used in gas-insulated switchgear, the first blade and the second blade are assembled by adopting a first pushing device and a combination part, which can avoid manual assembly by workers and ensure the safety of workers.

[0009] Optionally, according to the assembly equipment described above, the assembled first blade is perpendicular to the second blade; and / or

[0010] The first blade has a first strip-shaped hole that extends through one side of the first blade, and the second blade has a second strip-shaped hole that extends through one side of the second blade. The first pushing device is capable of pushing the second blade into the first strip-shaped hole and the first blade into the second strip-shaped hole.

[0011] This assembly method is relatively simple.

[0012] Optionally, according to the assembly equipment described above, the base has a first support groove capable of accommodating a first blade, and the first pushing device is capable of pushing the first blade in the first support groove into a first gap.

[0014] A first receiving section is used to receive several first blades;

[0024] Optionally, the assembly equipment described above may also include at least one of the following components:

[0025] The first linkage component includes a first rope and a first counterweight. The first counterweight is connected to one end of the first rope. The first rope can drive the first pushing device and the moving device to move simultaneously. As the moving device moves from the first position to the second position, the first pushing device can be driven to move to push the first blade into and partially extend out of the first gap.

[0067] To make the objectives, technical solutions, and advantages of this utility model clearer, the following embodiments are provided to further illustrate this utility model in detail. The nouns and pronouns referring to "person" in this patent application are not limited to specific genders.

[0068] This invention provides an assembly device for the blades of an explosion-proof membrane used in gas-insulated switchgear, to protect the safety of workers and avoid cuts during blade assembly.

[0069] like Figures 1 to 6 The diagram shown is a structural schematic of an assembly device for the blade of an explosion-proof membrane used in a gas-insulated switchgear according to the present invention.

[0070] The assembly equipment for the blade of the explosion-proof membrane used in gas-insulated switchgear includes a base 2, a first pushing device 3, and an assembly part 4.

[0071] The base 2 has a first slot 211, which is capable of accommodating a first blade 11. "Capable of accommodating the first blade 11" means that the blade can pass through the first slot 211 along its direction; that is, the first slot 211 is matched to the thickness of the blade. As an example, such as... Figures 1 to 6As shown, the base 2 has a raised strip 21, a first slit 211 located at the top of the raised strip 21 and extending through the raised strip 21 in the width direction, a first pushing device 3 located on one side of the raised strip 21, and an assembly part 4 located on the other side of the raised strip 21. The width direction mentioned here can be regarded as the first direction D1. Specifically, the direction in which the first blade 11 travels is the first direction D1.

[0072] The first pushing device 3 is used to push a first blade 11 into and partially protrude from the first gap 211. The first pushing device 3 pushes the first blade 11 into the first gap 211 from one side along a first direction D1, and partially protrudes from the first gap 211 from the other side. To limit the length of the first blade 11 protruding from the first gap 211, a limiting part 71 can be provided on the assembly equipment base 2, which is on the same side as the assembly part 4. After the first blade 11 partially protrudes from the first gap 211, it will eventually touch the limiting part 71, thus accurately positioning the length of the first blade 11 protruding, facilitating assembly. The direction of movement of the first pushing device 3 is also the first direction D1, and the direction perpendicular to the blade body of the first blade 11 is the second direction D2.

[0073] The assembly part 4 is capable of accommodating a second blade 12. This assembly part 4 is movably inserted into the base 2, and is capable of pushing the second blade 12 to assemble with the portion of the first blade 11 extending out of the first slot 211. The ability of the assembly part 4 to accommodate a second blade 12 can be limited by defining the thickness of the accommodating portion. As an example, the assembly part 4 moves along a third direction D3, that is, it pushes the second blade 12 along the third direction D3 to assemble the first blade 11 and the second blade 12. Figure 1 As shown, without pushing the second blade 12 to assemble with the first blade 11, the assembly part 4 is located below the first gap 211.

[0074] As an example, the assembled first blade 11 is perpendicular to the second blade 12, as shown below. Figure 6 As shown. This assembly method allows for reliable cutting of the explosion-proof membrane with fewer blades.

[0075] As an example, the first blade 11 has a first slotted hole 111 that extends through one side of the first blade 11, and the second blade 12 has a second slotted hole 121 that extends through one side of the second blade 12. The first pushing device 3 can push the second blade 12 into the first slotted hole 111 and the first blade 11 into the second slotted hole 121. The first blade 11 and the second blade 12 can have the same structure, which facilitates material management. Both the first blade 11 and the second blade 12 can be isosceles trapezoidal, with a slotted hole on the top (short) side. This slotted hole is, for example, located in the middle of the top side. The two blades are assembled by inserting them into each other through the two slotted holes. The width of the slotted hole can match the thickness of the blade, that is, the two blades can be assembled together by interference fit. This assembly method is relatively simple. Of course, the two blades can also be combined in other ways. For example, only the first blade 11 may have a first slotted hole 111, while the second blade 12 may not have a slotted hole. The second blade 12 can be inserted into the first slotted hole 111 for assembly. Other structures can also be used to assemble the two blades together, which will not be elaborated upon here. Figure 6 As shown, the two blades are assembled together vertically.

[0076] According to the assembly equipment for the blades of the explosion-proof membrane used in gas-insulated switchgear, the first blade 11 and the second blade 12 are assembled by using the first pushing device 3 and the assembly part 4, which can avoid manual assembly by the workers and ensure the safety of the workers.

[0077] As an example, the base 2 has a first bearing groove capable of accommodating one first blade 11. The first pushing device 3 can push the first blade 11 from the first bearing groove into the first gap 211. The fact that the first bearing groove can only accommodate one first blade 11 indicates that the thickness of the first bearing groove is limited, for example, matching the thickness of the first blade 11. In the second direction D2, only one first blade 11 can enter the first bearing groove, thus ensuring that the first pushing device 3 pushes only one first blade 11 into the first gap 211 at a time. Figure 1 The diagram shows the structure of the first blade 11 located in the first bearing groove, which is also part of the moving path of the first pushing device 3. For example, the first pushing device 3 can move along the first track 22, such as... Figure 2 As shown, a first track 22 can be provided on the base 2, and the first pushing device 3 moves along the first track 22. Of course, a first linkage component can also be provided for the first pushing device 3 to link with other components.

[0078] As an example, the assembly equipment also includes at least one of the following components: a first receiving portion 5 and a second pushing device 6. The first receiving portion 5 is used to receive a plurality of first blades 11. Figures 1 to 4 As shown, the first receiving portion 5 includes several long rods that form a receiving space capable of holding several first blades 11. Using long rods to form the first receiving portion 5 allows the operator to see the number of first blades 11 in the first receiving portion 5, enabling timely replenishment. More specifically, the base 2 includes a first plate 26 and a second plate 27, both perpendicular to the protruding strip 21, with both ends of each long rod fixed between the first plate 26 and the second plate 27. The second pushing device 6 is used to push one of the first blades 11 in the first receiving portion 5 onto the moving path of the first pushing device 3. More specifically, the second pushing device 6 can push the blade body of the first blade 11 along the second direction D2 and push a first blade 11 away from the second pushing device 6 into the first bearing groove, placing it on the moving path of the first pushing device 3. Furthermore, a second track 23 can be provided for the second pushing device 6, such as... Figure 3 As shown. The use of the second pushing device 6 can avoid manual contact with the blade.

[0079] As an example, to simplify the operation for staff, a second linkage component can be provided for the second pushing device 6. For example... Figure 4 As shown, the second linkage component includes a second rope 921 and a second counterweight (not shown in the figure). The second counterweight is connected to one end of the second rope 921. The second counterweight can drive the second rope 921 to move under the action of gravity, thereby driving the second pushing device 6 to push a first blade 11 onto the moving path of the first pushing device 3. Figure 4 As can be seen, the second rope 921 can be fixed and its direction of movement limited by the pulley assembly 94. Under the action of gravity, the second counterweight pulls the second rope 921 in the opposite direction of the third direction D3, thereby causing the second rope 921 to pull the second pushing device 6 in the second direction D2. The second pushing device 6 moves in the second direction D2, thereby pushing a first blade 11 into the first bearing groove. The first blade 11 is pushed away from the first bearing groove by the first pushing device 3 and the first pushing device 3 returns to... Figure 1 If the second counterweight does not enter the first bearing groove, the second rope 921 will continue to move due to the gravity of the second counterweight, and the second rope 921 will continue to pull the second pushing device 6 along the second direction D2, so that another first blade 11 will enter the first bearing groove.

[0080] The first pushing device 3 can push the first blade 11 along the first direction D1, and the second pushing device 6 can push the first blade 11 along the second direction D2. The extension direction of the blade body of the first blade 11 is also the first direction D1. This design makes the overall structure of the assembly equipment more compact.

[0081] As an example, the assembly part 4 can push the second blade 12 along a third direction D3 to assemble it with the first blade 11. The third direction D3 is perpendicular to the first direction D1 and the second direction D2. The top of the assembly part 4 is provided with a first support groove for accommodating one second blade 12. Figure 5 and Figure 6 As shown, the assembly 4 pushes the second blade 12 to contact and assemble with the first blade 11. The direction of movement of the assembly 4 can be limited by the space provided by the base 2 for the assembly 4, or a track can be set for the assembly 4. The specific choice can be made according to actual needs, which will not be elaborated here.

[0082] As an example, the assembly equipment also includes a moving device 7. This moving device 7 is movable between a first position and a second position. The moving device 7 has a second receiving portion 72 for accommodating a plurality of second blades 12. The second receiving portion 72 includes a plurality of long rods that form a receiving space capable of holding the plurality of second blades 12. The use of long rods to form the second receiving portion 72 allows the operator to see the number of second blades 12 in the second receiving portion 72, enabling timely replenishment. When the moving device 7 is in the first position, a second blade 12 can be pushed into the assembly portion 4; when the moving device 7 is in the second position, the moving device 7 is moved away from the assembly portion 4. Figures 2 to 4 As shown, when the moving device 7 is moved to the second position, the third pushing device 8 can push the second blade 12 into the first gap 211, causing the second blade 12 to enter the first bearing groove. Next, the moving device 7 moves from the second position to... Figure 1 The first position shown provides space for the first blade 11. A third track 24 can be provided for the third pushing device 8, which can move along the third track 24, as shown. Figure 2 As shown. Of course, a fourth track 25 can also be provided for the mobile device 7, such as... Figure 2 As shown.

[0083] As an example, to simplify the operation of the operator, a third linkage component can be provided for the mobile device 7. This third linkage component includes a third rope 931 and a third counterweight 932. The third counterweight 932 is connected to one end of the third rope 931. The third counterweight 932 can drive the third rope 931 to move under the action of gravity, which in turn drives the third pushing device 8 to push the second blade 12 along the first direction D1. The mobile device 7 moves from the second position to the first position, as shown below. Figure 1 As shown, when the moving device 7 moves to the first position, due to the gravity of the third counterweight 932, the third rope 931 can be pulled to move in the opposite direction of the first direction D1. Furthermore, the third rope 931 can pull the third pushing device 8 to move in the opposite direction of the first direction D1. Thus, the third pushing device 8 can push the second blade 12 in the opposite direction of the first direction D1, causing one of the second blades 12 near the protrusion plate to enter the second bearing groove 41 of the assembly part 4. Figure 2 and Figure 5 As can be seen, the protruding strip 21 has a groove in the third direction D3, and the assembly part 4 passes through the groove. The second bearing groove 41 can only bear one second blade 12 by limiting its thickness. When the moving device 7 moves from the first position to the second position, the second blade 12 in its second receiving part 72 will not fall down due to the support of the protruding strip 21. When the moving device 7 moves from the second position to the first position again, since there is no second blade 12 in the second bearing groove 41, the third counterweight 932 can automatically push a second blade 12 into the second bearing groove 41 by pulling the third pushing device 8 through the third rope 931 under the action of gravity. As an example, the moving device 7 has a limiting part 71. When the moving device 7 is in the second position, the limiting part 71 can limit the length of the first blade 11 extending out of the first gap 211. In this way, after the first blade 11 extends out of the first gap 211, it can abut against the moving device 7 and move to the limiting part 71. That is, a part of the moving device 7 can support the part of the first blade 11 extending out of the first gap 211. The height of the limiting part 71 is higher than the part used to support the first blade 11, so that the first blade 11 will not fall out of the first gap 211.

[0084] As an example, the first linkage device may include a first rope 911 and a first counterweight 912. The first counterweight 912 is connected to one end of the first rope 911. The first rope 911 can drive the first pushing device 3 and the moving device 7 to move simultaneously. During the movement of the moving device 7 from the first position to the second position, the first pushing device 3 can be moved to push the first blade 11 into and partially out of the first gap 211. The first counterweight 912 can, under the action of gravity, drive the first pushing device 3 to move away from the first gap 211, and drive the moving device 7 from the second position to the first position. This first linkage device can achieve automatic reset of the moving device 7 from the second position to the first position; the operator only needs to operate the moving device 7 to move it from the first position to the second position. The first rope 911 can change the direction of force transmission through various pulley assemblies 94.

[0085] As an example, the assembly equipment also includes a housing (not shown in the figure), in which the base 2, assembly part 4, and first pushing device 3 are all located. The housing has an opening, through which the first pushing device 3 can push the assembled first blade 11 and second blade 12 out. The housing can be made of metal or rubber material and covers the base 2, assembly part 4, and first pushing device 3. It also covers the second pushing device 6, third pushing device 8, moving device 7, etc. The opening on the housing is, for example, cross-shaped, which matches the assembled first blade 11 and second blade 12. The assembly part 4 pushes the assembled first blade 11 and second blade 12 out of the opening. The operator can use tweezers to hold the assembled first blade 11 and second blade 12 and then install them to form an explosion-proof membrane.

[0086] The first pushing device 3, the second pushing device 6, the third pushing device 8, and the moving device 7 mentioned above can be pushed manually or electrically, which will not be elaborated here.

[0087] The following example illustrates the working process of the assembly equipment for the blades of the explosion-proof membrane used in gas-insulated switchgear. For instance... Figures 1 to 6 As shown, Figure 1 A schematic diagram of the structure is shown, in which the first pushing device 3 is in the avoidance position, the moving device 7 is in the first position, and the assembly part 4 is in the third position. Figure 2 The diagram shows a structural schematic of the first pushing device 3 moving from the avoidance position to the pushing position, the moving device 7 moving from the first position to the second position, and the assembly part 4 at an angle in the third position. Figure 3 A schematic diagram of a structure is shown at an angle, with the first pushing device 3 in the pushing position, the moving device 7 in the second position, and the assembly part 4 in the third position. Figure 4A structural schematic diagram is shown from another angle, showing the first pushing device 3 in the pushing position, the moving device 7 in the second position, and the assembly part 4 in the third position; Figure 5 This is a partially enlarged schematic diagram of the assembly part 4 located in the third position; Figure 6 This is a schematic diagram of the assembly position at the fourth position, at which point the first blade 11 and the second blade 12 are assembled.

[0088] The workers first place several first blades 11 into the first receiving part 5 with their blades overlapping, and then place several second blades 12 into the second receiving part 72 with their blades overlapping. The figure shows that there are certain gaps between each first blade 11 and each second blade 12, mainly to illustrate the structure of the blades. In practice, each blade can be placed close to the adjacent blades.

[0089] like Figure 1 As shown, due to the action of the second linkage component, after each first blade 11 is placed into the first receiving part 5, the second counterweight can drive the second rope 921 to pull the second pushing device 6 to automatically push the first blade 11 of the first receiving part 5 along the second direction D2, pushing the first blade 11 away from the second pushing device 6 into the first bearing groove. At this time, the first pushing device 3 is in the avoidance position, which means that the first pushing device 3 avoids the first bearing groove, that is, the first pushing device 3 has not yet pushed the first blade 11 in the first bearing groove. Similarly, due to the action of the third linkage component, after each second blade 12 is placed into the second receiving part 72, the third counterweight 932 can drive the third rope 931 to pull the third pushing device 8 to push each blade in the second receiving part 72 of the moving device 7 located in the second position along the opposite direction of the first direction D1, and push the second blade 12 away from the third pushing device 8 into the second bearing groove of the assembly part 4, which is located directly below the first gap 211. At this time, the assembly part 4 is in the third position, and from Figure 1 It can also be seen that the limiting part 71 does not correspond to the first gap 211.

[0090] Next, as Figure 2As shown, the operator can apply force to the moving device 7, causing it to move from the first position to the second position. Since the end of the second receiving portion 72 furthest from the third pushing device 8 is abutted against the protruding strip 21, the second blades 12 will not fall over. Furthermore, due to the action of the first linkage assembly, the moving device 7 can drive the first pushing device 3 to move from the avoidance position to the pushing position via the first rope 911, i.e., moving along the first direction D1. During this process, the first pushing device 3 gradually approaches the first blade 11 in the first bearing groove and pushes the first blade 11 into the first gap 211, and the first blade 11 gradually extends out from the other side of the first gap 211. The portion passing through the first gap 211 can continue to be supported by the moving device 7. Of course, if...

[0091] Next, as Figures 3 to 5 As shown, when the moving device 7 moves to the second position, the first blade 11 extends out of the first gap 211 and touches the limiting part 71, which limits the length of the first blade 11 extending out of the first gap 211. At this time, the first pushing device 3 also reaches the contact position. Due to the setting of the first gap 211, the first strip hole 111 on the first blade 11 is aligned with the second strip hole 121 on the second blade 12, and the first blade 11 and the second blade 12 are perpendicular. During the process of the first pushing device 3 pushing the first blade 11, the first blade 11 passes through the second strip hole 121, as... Figure 5 As shown.

[0092] Then, as Figure 6 As shown, the assembly part 4 moves upward from the third position along the third direction D3, thereby causing the second blade 12 to be inserted into the first strip hole 111 and the first blade 11 to be inserted into the second strip hole 121 and assembled in place. Figure 6 A schematic diagram showing the assembly part 4 in the fourth position is shown.

[0093] After the two blades are assembled, the assembly unit 4 continues to push the first blade 11 upward along the third direction D3, so that the two assembled blades are positioned where they can be retrieved by the operator, for example, by extending from an opening in the housing of the assembly equipment. The operator can then use tweezers to remove the two assembled blades and assemble them into the explosion-proof membrane.

[0094] As can be seen, the staff will not touch the blade with their hands throughout the process, which greatly reduces the risk of the staff cutting their hands.

[0095] Next, the operator can release the force applied to the moving device 7. Under the action of the first counterweight 912, the moving device 7 moves from the second position to the first position, and the first pushing device 3 moves from the pushing position to the avoiding position, returning to its original position. Figure 1The state shown. When the first pushing device 3 is in the avoidance position, due to the action of the second counterweight, a first blade 11 enters the first bearing groove, and due to the action of the third counterweight 932, a second blade 12 enters the second bearing groove.

[0096] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
