Description

Technical Field

[0001] This utility model relates to a mechanism lifting tool, specifically to a limit-positioning buckle module, and a Marx generator mechanism lifting tool based on the limit-positioning buckle module, used for lifting the Marx generator mechanism in a large pulse power device. Background Technology

[0002] Large-scale pulse power devices utilize Marx generators to produce primary high-voltage pulses, with the core component being the motor. The motor uses a grid-like nylon plate as its frame, forming a rectangular structure 3-4 meters long. It contains various components such as capacitors, resistors, and switches, weighing approximately 1 ton, classifying it as a large, precision, high-voltage assembly. During the construction and operation of large-scale pulse power devices, a gantry crane is required to hoist the entire motor. Traditional hoisting methods involve directly threading slings through the nylon plate, which is prone to slippage. Furthermore, accurately maintaining the center of gravity during operation leads to unstable hoisting of the motor, making horizontal movement and placement impossible, thus affecting operational safety. In addition, the large number of motors and the need for repeated hoisting require significant time for sling disassembly, assembly, and adjustment, severely impacting the efficiency of motor hoisting operations.

Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0054] like Figure 1 , Figure 2 As shown, a limit-positioning buckle module includes a buckle base plate 1, two guide rods 2, a buckle slot block 3, a push-pull long pin 4, a fixed front plate 5, a fixed rear plate 6, a push-pull handle 7, a front limit screw 8, a rear limit screw 9, a long pin retaining spring 10, and multiple hexagon socket head cap screws.

[0055] The snap-fit ​​base plate 1, the front fixing plate 5, and the rear fixing plate 6 are all flat structures and made of 304 stainless steel. The snap-fit ​​base plate 1 has four through holes for connecting to the external lifting frame 11. Additionally, the front fixing plate 5 and the rear fixing plate 6 each have three threaded holes. Corresponding countersunk holes are formed at both ends of the snap-fit ​​base plate 1 at the positions of the threaded holes in the front fixing plate 5 and the rear fixing plate 6. Six M8 socket head cap screws pass through the six countersunk holes on the snap-fit ​​base plate 1 and are threaded into the corresponding threaded holes on the front fixing plate 5 and the rear fixing plate 6 to fix the front fixing plate 5 and the rear fixing plate 6 to both ends of the lower surface of the snap-fit ​​base plate 1.

[0056] The guide rod 2 is a cylindrical structure with a diameter of 16mm, made of 304 stainless steel. Two guide rods 2 are arranged parallel to each other between the front fixing plate 5 and the rear fixing plate 6, serving as the guide structure for the snap-fit ​​slot block 3. Specifically, each end of the two guide rods 2 has a threaded hole. The front fixing plate 5 has a first countersunk hole axially formed at the corresponding positions of the two guide rods 2, and the rear fixing plate 6 has a second countersunk hole 62 axially formed at the corresponding positions of the two guide rods 2. Four M8 socket head cap screws pass through the first countersunk hole on the front fixing plate 5 and the second countersunk hole 62 on the rear fixing plate 6, respectively, and are threaded into the corresponding threaded holes at both ends of the guide rods 2.

[0057] The snap-fit ​​slot 3 is a U-shaped integral structure, including a vertical plate 31 and an upper horizontal plate 32 and a lower horizontal plate 33 vertically connected to the two ends of the vertical plate 31 on the same side; a slot is formed between the vertical plate 31, the upper horizontal plate 32, and the lower horizontal plate 33 for engaging the receiving limiting component. The vertical plate 31, the upper horizontal plate 32, and the lower horizontal plate 33 are all made of 45# steel. Figure 3 As shown, the vertical plate 31 has two sliding through holes 311 and one stepped through hole 312 that pass through the horizontal direction of the upper horizontal plate 32 at the position corresponding to the upper horizontal plate 32. The snap-fit ​​block 3 is slidably connected to the two guide rods 2 through the two sliding through holes 311 of the upper horizontal plate 32. That is, the two guide rods 2 pass through the two sliding through holes 311 respectively, and the outer side wall of the guide rod 2 is in clearance fit with the inner side wall of the sliding through hole 311 to ensure that the snap-fit ​​block 3 slides smoothly along the guide rod 2 without obvious wobbling. The stepped through hole 312 is located between the two sliding through holes 311, and the larger diameter end of the stepped through hole 312 faces the side of the fixed front plate 5, and the smaller diameter end faces the side of the fixed rear plate 6.

[0058] The main body of the push-pull pin 4 is a cylindrical structure made of 304 stainless steel. One end has a tip, the diameter of which is smaller than the inner diameter of the large-diameter end of the stepped through hole 312 but larger than the inner diameter of the small-diameter end of the stepped through hole 312. The other end of the push-pull pin 4 passes through the stepped through hole 312 and is engaged within the stepped through hole 312, allowing the push-pull pin 4 to rotate relative to the stepped through hole 312, but preventing axial movement. Preferably, in this embodiment, the outer wall of the tip is clearance-fitted with the inner wall of the large-diameter end of the stepped through hole 312.

[0059] A connecting limiting groove is coaxially formed on one side of the upper horizontal plate 32 corresponding to the small diameter end of the stepped through hole 312. A retaining ring groove is provided on the push-pull long pin 4 near its end. The long pin retaining ring 10 is a shaft elastic retaining ring - type A standard part, which is installed in the retaining ring groove through the limiting groove to axially limit the push-pull long pin 4, so that the retaining block 3 can move axially with the push-pull long pin 4, but does not affect the rotation of the push-pull long pin 4 relative to the retaining block 3. In this embodiment, the main body diameter of the push-pull long pin 4 is 12mm, the end diameter is 16mm, the inner diameter of the small diameter end of the stepped through hole 312 is 12mm, the inner diameter of the limiting groove is 20mm, and the inner diameter of the long pin retaining ring 10 is 11mm.

[0060] Both the front limit screw 8 and the rear limit screw 9 are standard M4 socket head cap screws. Two M4 radial threaded holes are located on the same side of the middle of the push-pull pin 4, used to connect the front limit screw 8 and the rear limit screw 9 sequentially from left to right. A gourd-shaped irregular through hole is provided on the fixed rear plate 6 corresponding to the position of the push-pull pin 4. The larger semicircle is used for the sliding passage of the push-pull pin 4, and the smaller semicircle is used for the passage of the front limit screw 8 and the rear limit screw 9. Figure 4 As shown, after the front limiting screw 8 and the rear limiting screw 9 rotate with the push-pull pin 4, they will be unable to pass through the aforementioned irregular through hole, thereby limiting the push-pull pin 3 and preventing the buckle slot block 3 from moving unexpectedly. Specifically, when the buckle slot block 3 slides to the leftmost end, it is limited by the rear limiting screw 9 on the left side of the fixed back plate 6. When the buckle slot block 3 slides to the rightmost end, the front limiting screw 8 and the rear limiting screw 9 pass through the fixed back plate 6 with the push-pull pin 4 and are then limited by the front limiting screw 8 on the right side of the fixed back plate 6.

[0061] The push-pull handle 7 is a long, flat plate structure made of 304 stainless steel, with two countersunk holes. The other end of the push-pull pin 4 is provided with two M3 threaded holes. Two M3 socket head cap screws are threadedly connected to the corresponding M3 threaded holes on the push-pull pin 4 through the two countersunk holes on the push-pull handle 7, so that the push-pull pin 4 can be rotated by rotating the push-pull handle 7.

[0062] The installation and debugging steps of the limit-positioning buckle module of this utility model are as follows:

[0063] Step 1: Based on the snap-fit ​​base plate 1, use multiple standard hexagon socket screws to install and fix the front plate 5, two guide rods 2, push-pull long pin 4, snap-fit ​​slot block 3, long pin retaining spring 10, fix the rear plate 6, push-pull handle 7, front limit screw 8 and rear limit screw 9 in sequence.

[0064] Step 2: Rotate the push-pull handle 7 to make it approximately vertical, and then repeatedly push and pull the push-pull handle 7 to make the buckle slot block 3 slide back and forth along the guide rod 2 to ensure smooth sliding without jamming.

[0065] Step 3, Adjust the limit function: Push the latching block 3 fully in (slide the latching block 3 to the leftmost end), and ensure the push-pull handle 7 is in a nearly horizontal position, such as... Figure 5 As shown, the rear limit screw 9 prevents the latching block 3 from accidentally moving outward. The latching block 3 is fully pulled out (the latching block 3 slides to its rightmost end), and the push-pull handle 7 is in a nearly horizontal position, as... Figure 6 As shown, the front limit screw 8 prevents the buckle slot block 3 from moving inwards unexpectedly.

[0066] Step 4: Tighten all the standard hex socket screws to complete the assembly of the limit snap-fit ​​module.

[0067] Based on the aforementioned limit-positioning buckle module, this utility model also provides a Marx generator movement lifting tool, such as... Figure 7 As shown, this embodiment includes a lifting frame 11, two lifting lugs 12, twelve limit-positioning buckle modules 14, and six support blocks 13.

[0068] The lifting frame 11 is a rectangular frame structure, welded from hollow square steel with a side length of 80mm and a wall thickness of 5mm. The hollow square steel is made of Q235 material. Two lifting lugs 12 are symmetrically welded to the upper surface of the lifting frame 11 along the length direction. The position of the lifting lugs is selected with consideration of the center of gravity of the Marx generator mechanism, so that the mechanism can be kept stable during lifting.

[0069] The lower surface of the lifting frame 11 is provided with multiple sets of threaded holes symmetrically arranged in pairs along the width direction. These holes are used to connect the twelve limit-positioning buckle modules 14 and the six support blocks 13 to the lower surface of the lifting frame 11 through M8 socket head cap screws, thereby achieving fixation.

[0070] Twelve limit-positioning buckle modules 14 are arranged in two rows, symmetrically installed in pairs on the lower surface of the lifting frame 11 along the width direction, with the push-pull handle 7 facing outwards. For example... Figure 8As shown, the support block 13 has a cuboid structure made of nylon, with a limiting boss 131 on one side of its lower surface. Six support blocks 13 are arranged in two rows, symmetrically installed on the lower surface of the lifting frame 11 along the width direction, with the limiting boss 131 located on the outer side. This allows the symmetrical rows of limiting bosses 131 to constrain the relative position of the lifting device and the mechanism. The limiting buckle module 14 is offset from the support block 13. The lower surface of the support block 13 is used to fit against the upper surface of the nylon plate of the Marx generator mechanism, and the limiting boss 131 is located on the outer side of the Marx generator mechanism. The buckle slot 3 of the limiting buckle module 14 is used to engage with the outer side of the upper frame of the nylon plate of the Marx generator mechanism.

[0071] like Figure 9 The diagram shows the usage of the Marx generator core lifting device of this utility model. The core lifting device 15 is the overall structure of the Marx generator core lifting device of this utility model; the lifting strap 16 is a commonly used lifting tool, with two straps of the same length. In this embodiment, a lifting strap 16 with a length of 2 meters and a weight limit of 3 tons is used; the nylon plate 17 is a flat plate structure with a grid, and six nylon plates 17 are assembled to form the core frame.

[0072] The installation and use steps of this utility model Marx generator core lifting tool are as follows:

[0073] Step 1: Install the twelve limit-locking buckle modules 14 and the six support blocks 13 onto the lifting frame 11, ensuring a tight connection;

[0074] Step 2: Lift the assembled movement lifting device 15 using two lifting straps 16, as follows: Figure 10 As shown in (a), pull out all the latching slots 3 of the limit latching module 14 and rotate the push-pull handle 7 to make it approximately horizontal. At this time, due to the action of the front limit screw 8, the latching slots 3 are prevented from moving inward unexpectedly.

[0075] Step 3: Place the movement lifting device 15 stably on top of the movement frame, so that the support block 13 is in contact with the upper surface of the nylon plate 17, and the nylon plate 17 is inside the limiting boss 131 of the support block 13.

[0076] Step 4, as follows Figure 10 As shown in (b), rotate the push-pull handle 7 to make it approximately vertical, and push each buckle slot 3 into the next to fit it against the frame of the nylon plate 17. Then rotate the push-pull handle 7 to make it approximately horizontal. At this time, due to the action of the rear limit screw 9, the buckle slot 3 is prevented from accidentally moving outward.

[0077] Step 5: Slowly lift the movement so that it can be smoothly moved to the predetermined location by the movement lifting device 15;

[0078] Step 6: Pull out all the buckle slots 3 of the limit buckle module 14, rotate the push-pull handle 7 to make it approximately horizontal, and slowly lift it to separate the mechanism lifting device 15 from the mechanism, thus completing one mechanism lifting operation.

[0079] The above description is only used to illustrate the technical solution of this utility model, and is not intended to limit it. For those skilled in the art, modifications can be made to the specific technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features. However, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions protected by this utility model.
