Description

Technical Field

[0001] The invention relates to a cable intermediate joint demoulding machine, in particular to an intermediate joint mold disassembly and assembly platform. Background Art

[0002] With the development of my country's power construction, the demand for electricity continues to rise, and the demand for power cables is increasing. The widespread application of cross-linked polyethylene insulated power cables has promoted the rapid development of cable accessories. Cross-linked cables are widely used in urban networks. Since the manufacturing length of cables is limited by production equipment and transportation conditions, the manufacturing length of high-voltage cables is generally between 400 and 800 meters, and the length of cable lines is generally around 2km. Therefore, the development of urban power grids will require a large number of cable intermediate joints. The external cavity of the cross-linked cable intermediate joint rubber part mold is usually a half-split structure, that is, the external cavity is composed of two symmetrical halves of the mold. The assembled external cavity is cylindrical, and a compression jacket is required to press the two halves of the mold against each other to prevent the external cavity from causing gaps at the joint due to the injection pressure during the injection process. Because the manufactured intermediate joint is used for power cables, the intermediate joint itself is large in size and heavy in weight, and the corresponding outer jacket and external cavity are also large in volume. During production, the entire intermediate joint manufacturing mold is pressed and dismantled by manpower, which is not only labor-intensive and low in production efficiency, but also poses a great safety hazard to the personal safety of production workers.

[0031] Referring to Figures 1 to 6 , a disassembly and assembly table for an intermediate joint mold according to an embodiment of the present invention. The intermediate joint mold includes an outer sleeve 110, an external cavity 120, and a core component 130. The external cavity 120 is coated on the outer peripheral surface of the core component 130, and the outer sleeve 110 is coated on the outer peripheral surface of the external cavity 120. The disassembly and assembly table includes: a frame 200 provided with a positioning bracket 210 for positioning the intermediate joint mold placed thereon; a disassembly and assembly mold table 300 provided at one end of the positioning bracket 210 for separating the external cavity 120 and the core component 130; a main push rod 400 slidably installed on the frame 200 and connected to a driving device capable of driving its horizontal sliding; one end of the main push rod 400 is provided with a tail end locking device 410 matching the end of the external cavity 120. When the tail end locking device 410 abuts against the end of the external cavity 120 away from the disassembly and assembly mold table 300 and slides in the direction of the disassembly and assembly mold table 300, the external cavity 120 and the core component 130 can be pushed out of the outer sleeve 110 to the disassembly and assembly mold table 300.

[0032] In some embodiments of the present invention, the frame 200 includes a tail end plate 220, a first vertical plate 230, a second vertical plate 240, and a front end plate 250 arranged at intervals. The front end plate 250 and the tail end plate 220 are respectively arranged at the front and rear ends of the frame 200, and the first vertical plate 230 and the second vertical plate 240 are arranged in the middle of the frame 200; the positioning bracket 210 is arranged between the first vertical plate 230 and the second vertical plate 240, the disassembly and assembly mold table 300 is arranged between the second vertical plate 240 and the front end plate 250, and the main push rod 400 slidably passes through the first vertical plate 230. Specifically, as Figures 1 to 3As shown in the figure, the frame 200 includes a base 201. On the base 201, a tail end plate 220, a first vertical plate 230, a second vertical plate 240, and a front end plate 250 are arranged at intervals. The tail end plate 220 and the front end plate 250 are respectively arranged at both ends of the base 201 in the length direction. Both the first vertical plate 230 and the second vertical plate 240 are arranged between the tail end plate 220 and the front end plate 250, dividing the base 201 into three sections: an intermediate section, a first section near the tail end plate 220, and a second section near the front end plate 250. The positioning bracket 210 is arranged in the intermediate section, and the disassembly and assembly die table 300 is arranged in the second section. A through hole for the main push rod 400 to pass through is provided in the middle of the first vertical plate 230, and the main push rod 400 is inserted into the through hole of the first vertical plate 230. Before operation, the rod body part of the main push rod 400 is located in the first section, and the tail end locking device 410 is located at a place in the intermediate section close to the first section. The main push rod 400 is used to push the external cavity 120 and the core assembly 130 out of the outer sleeve 110 into the disassembly and assembly die table 300.

[0033] In some embodiments of the present invention, a main push oil cylinder 221 is provided on the tail end plate 220. The main push oil cylinder 221 is used to push the main push rod 400 to move, and further drive the main push rod 400 to push the external cavity 120 and the core assembly 130 to separate from the outer sleeve 110.

[0034] In some embodiments of the present invention, a main push plate 420 is provided between the tail end plate 220 and the first vertical plate 230. One end of the main push rod 400 far from the tail end locking device 410 is inserted into the main push plate 420; a first telescopic oil cylinder 260 is provided between the first vertical plate 230 and the second vertical plate 240. The telescopic end of the first telescopic oil cylinder 260 extends between the tail end plate 220 and the first vertical plate 230 and is connected to the main push plate 420. The first telescopic oil cylinder 260 is used to drive the main push plate 420 to slide and further drive the main push rod 400 to slide. Specifically, as Figure 3 shown, the main push rod 400 pushing the external cavity 120 and the core assembly 130 from the positioning bracket 210 to the disassembly and assembly die table 300 is divided into two steps. The first step is to push the external cavity 120 and the core assembly 130 to act through the main push oil cylinder 221. The thrust of the main push oil cylinder 221 is large and can push the outer peripheral wall of the external cavity 120 to separate from the outer sleeve 110. However, the stroke of the main push oil cylinder 221 is limited and cannot push the external cavity 120 and the core assembly 130 to move to the disassembly and assembly die table 300. Its function is only to separate the external cavity 120 from the outer sleeve 110. The second step is to push the main push rod 400 to slide through the main push plate 420. The main push plate 420 is driven to slide horizontally through the first telescopic oil cylinder 260. Then the main push plate 420 drives the main push rod 400 to slide horizontally. The main push rod 400 then pushes the external cavity 120 and the core assembly 130 to move from the positioning bracket 210 into the disassembly and assembly die table 300.

[0035] In some specific embodiments of the present invention, both ends of the fixed end of the first telescopic oil cylinder 260 are respectively arranged on the first vertical plate 230 and the second vertical plate 240, the telescopic end is arranged in the direction towards the tail end plate 220, and the end of the telescopic end is connected to the main push plate 420. The telescopic end of the first telescopic oil cylinder 260 is in the extended state before the intermediate joint mold is placed on the positioning bracket 210. One end of the main push rod 400 away from the tail end locking device 410 passes through the main push plate 420 and abuts against the main push oil cylinder 221; after the main push oil cylinder 221 operates, the first telescopic oil cylinder 260 operates, and the telescopic end of the first telescopic oil cylinder 260 retracts. Both the first telescopic oil cylinder 260 and the main push oil cylinder 221 are hydraulically driven.

[0036] It should be noted that there are two first telescopic oil cylinders 260, and the two first telescopic oil cylinders 260 are arranged at intervals left and right.

[0037] In a further embodiment of the present invention, a first sliding rod 280 is further arranged between the tail end plate 220 and the second vertical plate 240. The first sliding rod 280 passes through the first vertical plate 230, and both ends of the first sliding rod 280 are respectively connected to the tail end plate 220 and the second vertical plate 240. The first vertical plate 230 is a rectangular plate, and there are four first sliding rods 280. The four first sliding rods 280 respectively pass through the four corner positions of the first vertical plate 230. The first sliding rod 280 is used to limit the main push rod 400; the main push plate 420 is also a rectangular plate, and the first sliding rod 280 also passes through the four corner positions of the main push plate 420. By limiting the four corner positions of the main push plate 420, it is ensured that the main push plate 420 can always slide horizontally during sliding, avoiding the deformation and bending of the first telescopic oil cylinder 260 caused by the distortion or inclination of the main push plate 420, thereby affecting the sliding of the main push plate 420.

[0038] In some embodiments of the present invention, a bracket 430 is further arranged between the first vertical plate 230 and the second vertical plate 240. The main push rod 400 passes through the bracket 430, and the bracket 430 is used to support the main push rod 400. Since the weight of the main push rod 400 is relatively large, in order to ensure that the main push rod 400 will not be bent and deformed due to its own weight, the bracket 430 is provided to support the main push rod 400. The bracket 430 is an inverted triangle, with one angle vertically downward and provided with a round hole. The two upper first sliding rods 280 pass through the two upper angles of the bracket 430, and the main push rod 400 passes through the round hole facing downward of the bracket 430. The weight of the main push rod 400 is applied to the first sliding rod 280 through the bracket 430, reducing the possibility of the main push rod 400 being bent due to gravity.

[0039] In a further embodiment of the present invention, a telescopic cylinder 431 is provided above the first vertical plate 230. The fixed end of the telescopic cylinder 431 is connected to the first vertical plate 230, and the telescopic end is connected to the bracket 430 for driving the push plate to slide. It should be noted that the telescopic end of the telescopic cylinder 431 is not long, so the stroke of the bracket 430 is not long either. Since the main push rod 400 slides through the bracket 430, the bracket 430 does not always support the main push rod 400 at the same position.

[0040] It should be noted that after the main push oil cylinder 221 finishes its action, the telescopic cylinder 431 starts to act, and the actions of the telescopic cylinder 431 and the first telescopic oil cylinder 260 are basically carried out simultaneously.

[0041] In some embodiments of the present invention, a second telescopic oil cylinder 270 is further provided between the first vertical plate 230 and the second vertical plate 240, and a front-end locking device 440 matching the end of the external cavity 120 facing the dismounting and mounting die table 300 is provided between the second vertical plate 240 and the front-end plate 250. The telescopic end of the second telescopic oil cylinder 270 is connected to the front-end locking device 440 for driving the front-end locking device 440 to slide horizontally. Specifically, as Figure 3 , Figure 6 shown, a second sliding rod 290 is provided between the second vertical plate 240 and the front-end plate 250. The second sliding rod 290 is similar to the first sliding rod 280, but the rod body diameter of the second sliding rod 290 is smaller than that of the first sliding rod 280. The front-end locking device 440 is connected with a locking slide plate 450, and the front-end locking device 440 is installed on the side of the locking slide plate 450 facing the second vertical plate 240. The shape of the locking slide plate 450 is similar to that of the bracket 430. There are also four second sliding rods 290. Two second sliding rods 290 are respectively passed through the left and right sides of the locking slide plate 450; a connecting hole 451 protruding downward is provided in the middle of the locking slide plate 450, and the front-end locking device 440 is bolted to the hole wall of the connecting hole 451. The two ends of the second sliding rod 290 are respectively connected to the front-end plate 250 and the second vertical plate 240; the fixed ends of the second telescopic oil cylinder 270 are respectively installed on the first vertical plate 230 and the second vertical plate 240, and the telescopic end of the second telescopic oil cylinder 270 is connected to the locking slide plate 450. The second telescopic oil cylinder 270 is used to drive the locking slide plate 450 to slide along the second sliding rod 290.

[0042] In a further embodiment of the present invention, the front-end locking device 440 includes a cylinder body 441. One end of the cylinder body 441 is connected to the connection hole 451, and the other end is provided with an axially open slot 442. The slot 442 is matched with the end of the external cavity 120 for limiting the end of the external cavity 120. Four positioning posts 123 axially extending out of the end of the external cavity 120 are provided at the end of the external cavity 120, and the cylinder body 441 is provided with four slots 442 matched with the positioning posts 123. The cylinder body 441 is a hollow cylinder with one end open, and the open end faces the direction of the second vertical plate 240. A spring sleeve 445 is installed inside the cylinder body 441. A spring base 444, a buffer spring 446 and a top column 447 are installed inside the spring sleeve 445. The two ends of the buffer spring 446 are respectively abutted against the spring base 444 and the top column 447. The buffer spring 446 and the top column 447 pass through the spring sleeve 445. The top column 447 is used to abut against the end of the core assembly 130. One end of the top column 447 away from the second vertical plate 240 passes through the spring sleeve 445 and abuts against the end of the spring sleeve 445 facing the second vertical plate 240. The spring sleeve 445 is used to limit the top column 447 to prevent the top column 447 from sliding.

[0043] It should be understood that the structure of the tail-end locking device 410 at the end of the main push rod 400 is the same as that of the rear-end locking device. After the intermediate joint mold is placed on the positioning bracket 210, the second telescopic cylinder 270 will drive the front-end locking device 440 to slide in the direction of the second vertical plate 240, so that the cylinder body 441 of the front-end locking device 440 passes through the second vertical plate 240, and the positioning posts 123 at the end of the external cavity 120 are inserted into the slots 442 to achieve pre-positioning.

[0044] In some specific embodiments of the present invention, the front plate 250 is provided with a stop frame 251. The stop frame 251 protrudes in the direction away from the second vertical plate 240, for providing a receiving space for the front-end locking device 440 and limiting the stroke of the front-end locking device 440. The two ends of the second sliding rod 290 are respectively connected to the second vertical plate 240 and the stop frame 251.

[0045] In some embodiments of the present invention, the disassembly and assembly mold table 300 includes a slide rail 310. The sliding direction of the slide rail 310 is the same as the sliding direction of the main push rod 400. An elevating table 320 is provided on the slide rail 310. The elevating table 320 is used to receive the external cavity 120 and the core assembly 130. The elevating table 320 is connected with a power device capable of driving it to slide along the slide rail 310. Specifically, such as Figure 4As shown, a slide table 321 is provided on the slide rail 310. The lifting table 320 is connected to the slide table 321, and the slide table 321 is connected with a cylinder for driving it to slide along the slide rail 310; the lifting table 320 is also connected with a cylinder for driving its lifting. Since the weights of the external cavity 120 and the core assembly 130 are relatively large, in order to prevent the main push rod 400 from bending due to excessive force at the end during the process of pushing the external cavity 120 and the core assembly 130 to the disassembly and assembly mold table 300, before the external cavity 120 and the core assembly 130 are pushed to the disassembly and assembly mold table 300, the slide table 321 will slide to a position close to the second vertical plate 240. When the ends of the external cavity 120 and the core assembly 130 are pushed above the slide rail 310, the lifting table 320 rises to support the external cavity 120 and the core assembly 130 and moves along with the sliding of the external cavity 120 and the core assembly 130.

[0046] It can be understood that the lifting table 320 is arranged as a lifting structure so as not to hinder the horizontal sliding of the front-end locking device 440.

[0047] In some embodiments of the present invention, the external cavity 120 includes an upper cavity 121 and a lower cavity 122; cone block oil cylinders 330 are provided on both sides of the slide rail 310, and the output end of the cone block oil cylinder 330 is connected with a cone block 331. The cone block oil cylinder 330 is used to drive the cone block 331 to move to the connection part of the upper and lower cavities 122 to separate the upper cavity 121 and the lower cavity 122. Specifically, as Figure 5 shown, two positioning columns 123 are provided on both the upper cavity 121 and the lower cavity 122, and four opening slots 442 are also provided on the barrel 441. In order to achieve better sealing of the core assembly 130, the connection between the upper cavity 121 and the lower cavity 122 is relatively tight, so tools are needed to separate the two from the connection part. The cone block oil cylinder 330 is also a telescopic oil cylinder for driving the cone block 331 to move left and right. Four cone block oil cylinders 330 are provided, and the four cone block oil cylinders 330 are symmetrically arranged on both ends of the external cavity 120 left and right; when separating the upper cavity 121 and the lower cavity 122, the four cone block oil cylinders 330 act simultaneously to drive the cone block 331 to extend into the connection part of the upper cavity 121 and the lower cavity 122.

[0048] In a further embodiment of the present invention, both the upper cavity 121 and the lower cavity 122 are semi-cylindrical in shape, and a recess 124 is provided at each end of the upper cavity 121 and the lower cavity 122. The recess 124 is provided on the connecting surface of the upper cavity 121 and the lower cavity 122. Therefore, after the upper cavity 121 and the lower cavity 122 are connected, the recesses 124 of the two will form a groove for the tapered block 331 to extend into. The tapered block oil cylinder 330 acts to drive the tapered block 331 to extend into the groove formed by the recesses 124 of the upper cavity 121 and the lower cavity 122, facilitating the quicker separation of the upper cavity 121 and the lower cavity 122. The end of the tapered block 331 extending into the groove is wedge-shaped for easy insertion.

[0049] In a further embodiment of the present invention, a protective cover 350 is provided on the outer periphery of the tapered block 331. When the tapered block oil cylinder 330 is not actuated, the tapered block 331 is completely covered by the protective cover 350; the protective cover 350 is used to protect the tapered block 331 and limit its stroke. Specifically, as Figure 4 shown, strip-shaped grooves 332 are provided on both the front and rear sides of the outer peripheral wall of the tapered block 331, and the two strip-shaped grooves 332 are symmetrically arranged; correspondingly, threaded holes are provided in both the front and rear directions of the protective cover 350, and first bolts 351 are screwed into the threaded holes. The first bolts 351 pass through the housing of the protective cover 350 and enter the strip-shaped grooves 332 for circumferential and axial limiting of the tapered block 331, so that the tapered block 331 can only move along the length direction of the strip-shaped grooves 332, that is, the left-right direction. A strip-shaped hole 352 is also provided on the upper surface of the protective cover 350. A threaded hole is provided on the outer peripheral surface of the tapered block 331, and the orifice of the threaded hole faces upward. A second bolt 333 is screwed into the threaded hole, and the second bolt 333 is restricted within the strip-shaped hole 352. When the tapered block 331 moves left and right, the second bolt 333 moves accordingly. The first bolt 351 and the second bolt 333 are used to limit the length of the movement path of the tapered block 331. The protective cover 350 is fixedly connected to the tapered block oil cylinder 330. The first bolt 351 is provided at one end of the protective cover 350 away from the tapered block oil cylinder 330, and the second bolt 333 is provided at one end of the tapered block 331 close to the tapered block oil cylinder 330; when the tapered block 331 extends away from the tapered block oil cylinder 330 until the second bolt 333 abuts against the inner wall of the right end of the strip-shaped hole 352, it is the maximum extension length of the tapered block 331; when the tapered block 331 retracts towards the tapered block oil cylinder 330 until the first bolt 351 abuts against the right end wall of the strip-shaped groove 332, it is the stop point when the tapered block 331 is completely retracted; in summary, the first bolt 351 cooperating with the strip-shaped groove 332 and the second bolt 333 cooperating with the strip-shaped hole 352 achieve the stroke limit of the tapered block 331.

[0050] It can be understood that only one strip-shaped groove 332 can also be provided.

[0051] In some embodiments of the present invention, lifting brackets 340 are provided at both ends of the sliding direction of the sliding rail 310. A lifting cylinder 341 is connected to the bottom of the lifting bracket 340. The lifting cylinder 341 is used to drive the lifting bracket 340 to lift and lower to support the external cavity 120 and the core assembly 130. Specifically, as Figure 4 shown, the lifting bracket 340 can extend upward under the drive of the lifting cylinder 341, and the lifting bracket 340 is provided with a groove for the positioning post 123 to be embedded. The lifting bracket 340 extends upward until it contacts the positioning posts 123 at both ends of the lower cavity 122, so as to realize the support and limit of the external cavity 120 and the core assembly 130. Since the surface of the top of the lifting table 320 that contacts the surface of the lower cavity 122 is arc-shaped and cannot realize the left and right limit of the lower cavity 122, the lower cavity 122 is limited by the lifting bracket 340.

[0052] In some specific embodiments of the present invention, a lifting device is provided on one side of the disassembly and assembly die table 300 for lifting the separated upper cavity 121, the core assembly 130 and the lower cavity 122 out of the disassembly and assembly die table 300; therefore, after the external cavity 120 and the core assembly 130 are pushed to the disassembly and assembly die table 300, the tail end locking device 410 and the front end locking device 440 need to retract to facilitate the lifting device to lift the external cavity 120 and the core assembly 130. The lifting table 320 does not have the function of positioning the lower cavity 122 in the left and right directions. Therefore, the lifting bracket 340 needs to penetrate into the tail end locking device 410 or the front end locking device 440 to support the positioning post 123 before the tail end locking device 410 and the front end locking device 440 retract. Therefore, the tail end locking device 410 and the front end locking device 440 are both provided with a through slot 443 for the lifting bracket 340 to pass through.

[0053] In some embodiments of the present invention, the positioning bracket 210 includes a limiting plate 211 and a load-bearing block 212. A plurality of load-bearing blocks 212 are provided and arranged at intervals for receiving the intermediate joint mold; two limiting plates 211 are provided and are respectively arranged at both ends of the outer sleeve 110 along the sliding direction of the main push rod 400. The limiting plate 211 is used for axially limiting the outer sleeve 110. Specifically, as Figure 3 shown, the upper surface of the load-bearing block 212 is provided with an arc-shaped groove, and the radian diameter of the arc-shaped groove is the same as the diameter of the outer sleeve 110 of the intermediate joint mold. The outer peripheral surface of the outer sleeve 110 contacts the bottom of the arc-shaped groove to support and limit the intermediate joint mold. The limiting plate 211 is also provided with an arc-shaped groove, and the diameter of the arc-shaped groove is larger than the diameter of the external cavity 120 and smaller than the diameter of the outer sleeve 110. At the same time, the arc-shaped groove of the limiting plate 211 should be able to allow the tail end locking device 410 to pass through.

[0054] Further, the limiting plate 211 includes a front limiting plate close to the second vertical plate 240 and a rear limiting plate close to the first vertical plate 230. The rear limiting plate is connected to the base 201, and the front limiting plate is connected to the second vertical plate 240. When the main push rod 400 pushes the external cavity 120 and the core assembly 130 to move, the front limiting plate is mainly used to limit the outer sleeve 110 to complete the separation of the outer sleeve 110 and the external cavity 120. Therefore, the front limiting plate receives a large thrust and needs to be strengthened. If the bottom of the front limiting plate is connected to the base 201, the end of the front limiting plate away from the first vertical plate 230 has no support, which easily causes the front limiting plate to break or deform. Therefore, connecting the front limiting plate to the second vertical plate 240 can transfer the thrust received by the front limiting plate to the second vertical plate 240, so that the front limiting plate is not easily broken or deformed. Then, the second vertical plate 240 is connected to the tail end plate 220 through the side plate, so that the second vertical plate 240, the tail end plate 220 and the side plate form a frame-shaped whole, which not only increases the stability of the second vertical plate 240, but also makes the first slide bar 280 more stable. The function of the rear limiting plate is to limit the outer sleeve 110 when the external cavity 120 and the core assembly 130 are loaded into the outer sleeve 110.

[0055] The above describes the process of disassembling and separating the outer sleeve 110, the external cavity 120 and the core assembly 130 of the intermediate joint mold of the disassembly and assembly table of the present invention. It should be understood that the disassembly and assembly table of the present invention can also be used to assemble the intermediate joint mold, that is, the outer sleeve 110, the external cavity 120 and the core assembly 130 are assembled in the reverse procedure of mold disassembly. First, the lower cavity 122, the core assembly 130 and the upper cavity 121 are respectively lifted by the lifting device on one side of the disassembly and assembly mold table 300. First, the lower cavity 122 is lifted, then the core assembly 130 is lifted into the lower cavity 122, and finally the upper cavity 121 is pressed on the core assembly 130. Then, both the tail end locking device 410 and the front end locking device 440 act and are respectively connected to the front and rear ends of the external cavity 120, and then the second telescopic oil cylinder 270 and the first telescopic oil cylinder 260 act synchronously. At this time, the second telescopic oil cylinder 270 is used to provide the power to push the external cavity 120 and the core assembly 130 to move, and the first telescopic oil cylinder 260 acts as a buffer. The second telescopic oil cylinder 270 drives the external cavity 120 and the core assembly 130 to be loaded into the outer sleeve 110.

[0056] It should be understood that the core assembly 130 is not a cylinder with an equal diameter, but a frustum of a cone shape. The diameter of one end of the core assembly 130 is larger than that of the other end. Similarly, the external cavity 120 and the outer sleeve 110 are both frustum of a cone shapes. During the mold assembly or disassembly process, the end with a smaller diameter of the core assembly 130 faces backward, that is, towards the direction of the tail end plate 220, and the end with a larger diameter of the core assembly 130 faces the front end plate 250 direction, which is convenient for disassembly and assembly.

[0057] Further, before the second telescopic oil cylinder 270 operates, both the lifting frame 340 and the lifting platform 320 need to be retracted in advance to avoid obstructing the moving path of the front-end locking device 440.
