Description

Technical Field

[0001] This utility model relates to the field of cable armoring machine technology, and more specifically, to an automatic underground cable armoring machine. Background Technology

[0002] Cable armoring is a structural design that adds a metallic or non-metallic protective layer (such as steel strip or wire) to the outer layer of the cable. It is primarily used to enhance the cable's mechanical strength and prevent damage from external forces (such as compression, biting, and corrosion). Currently, some technical solutions use a rotating turntable to drive a steel coil to wrap and encase the cable during its traction movement, thus completing the armoring process. However, during the winding process, the cable can shift due to mechanical vibrations.

[0003] To solve the above problems, a search revealed that CN220155283U discloses an armoring machine for cable production. The instruction manual states that the cooperation between the movable rollers, connecting grooves, and forming blocks ensures that the cable will not deviate during operation.

[0004] However, this cable armoring machine still has some shortcomings in practical applications. For example, in the existing technology, the top of the armoring disc is connected by fixing bolts. Although the design intention is to facilitate disassembly for quick replacement, it is still not convenient enough in actual operation. In addition, because the support rod is fixedly connected to the armoring disc, the armoring disc cannot be disassembled as a whole; only the top cover can be removed to replace the steel strip roll. This structure limits operational efficiency, makes the replacement of the armored steel strip cumbersome, and affects overall production efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides an automatic downhole cable armoring machine to solve the problems of inconvenient disassembly, the lack of quick disassembly and assembly of some armoring machines in the prior art, and the fact that the support rod is fixed to the armoring disc, and only the top cover can be removed to replace the steel strip, resulting in low efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic armoring machine for downhole cables, comprising...

[0007] A base plate, on the top of which a fixing plate is installed;

[0008] The frame has connecting pipes fixedly sleeved in the middle of both the left and right sides. The ends of the two connecting pipes are rotatably installed on the inner surface of the middle of the two fixed plates. The frame has quick-release mechanisms in the middle of both the front and rear sides.

[0009] The quick-release mechanism includes a main rod, armor plate one, and armor plate two. The inner surface of the middle part of armor plate one is fixedly sleeved with the outer surface of the main rod, and the inner surface of the middle part of armor plate two is movably sleeved with the outer surface of the end of the main rod. Armor plate one and armor plate two are inserted and installed.

[0010] The quick-release mechanism further includes a limiting plate, a fixing ring, and a snap-fit ​​mechanism. The outer surface of the limiting plate is fixedly installed on the inner surface of the side of the frame. A motor is fixedly installed on the side surface of the limiting plate. A bidirectional lead screw is fixedly sleeved on the output end of the motor. Limiting blocks are threadedly connected to the outer surfaces of both ends of the bidirectional lead screw. The two limiting blocks are symmetrically arranged, and the outer surfaces of their ends are slidably installed with the inner surface of the limiting plate. Two fixing rings are fixedly sleeved on the end of the main rod away from the second armor plate, and their outer surfaces are snap-fitted with the inner surfaces of the limiting blocks. The snap-fit ​​mechanism is located inside the end of the main rod away from the fixing ring.

[0011] The locking mechanism includes a second motor, which is fixedly mounted on the surface of the end of the main rod. A main gear is fixedly sleeved on the output end of the second motor. Three driven gears mesh with the outer edge of the main gear. A shaft is fixedly sleeved on the middle of each of the three driven gears, and a limiting piece is fixedly installed on the outer surface of the shaft. The outer surface of the limiting piece is movably installed with the inner surface of the end of the main rod.

[0012] The base plate has a drive motor at its top, and a transmission mechanism is fixedly connected to the output end of the drive motor. The inner surface of the top end of the transmission mechanism is fixedly connected to the outer surface of the connecting pipe. A cleaning mechanism is provided on the left side of the base plate, and a dust box is provided at the bottom of the cleaning mechanism.

[0013] The cleaning mechanism includes a bracket, the side of which is fixedly mounted to the surface of a fixed plate. A roller is rotatably mounted on the top of the bracket. Three electric telescopic rods are fixedly mounted on the inner surface of the roller's sidewall. The three electric telescopic rods are arranged around the roller, and a brush plate is fixedly mounted on each end near the center of the roller. A toothed ring is fixedly sleeved on the outer surface of the roller's end. A gear one meshes with the outer edge of the toothed ring. A transmission mechanism two is sleeved on the side end of the middle of the gear one. The bottom end of the transmission mechanism two is fixedly sleeved to the output end of a drive motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The above technical solution employs a quick-release mechanism. A motor drives a bidirectional lead screw to rotate, causing the limiting block to slide and separate along the limiting plate, thereby releasing the main rod and armor plate one, enabling rapid replacement of the steel strip. Furthermore, the locking mechanism allows for the separate removal of armor plate one, facilitating material loading.

[0016] The above technical solution employs a cleaning mechanism. During cable feeding, the cable first passes through a roller, and an electric telescopic rod pushes a cleaning brush to adhere to the cable surface. The drive motor, through transmission mechanism two, drives gear one and a gear ring, causing the roller to rotate and clean the cable. Dust falls into the dust box, ensuring a smooth surface and improving armor quality. Attached Figure Description

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides an automatic armoring machine for downhole cables, including...

[0025] Base plate 1, with a fixing plate 2 installed on top of base plate 1;

[0026] The frame 4 has connecting pipes 3 fixedly sleeved in the middle of both the left and right sides. The ends of the two connecting pipes 3 are rotatably installed on the inner surface of the middle of the two fixed plates 2. The frame 4 has quick-release mechanisms 5 in the middle of both the front and rear sides.

[0027] The quick-release mechanism 5 includes a main rod 54, an armor plate 1 56, and an armor plate 2 57. The inner surface of the middle part of the armor plate 1 56 is fixedly sleeved with the outer surface of the main rod 54, and the inner surface of the middle part of the armor plate 2 57 is movably sleeved with the outer surface of the end of the main rod 54. The armor plate 1 56 and the armor plate 2 57 are inserted and installed.

[0028] The quick-release mechanism 5 also includes a limiting plate 50, a fixing ring 55, and a snap-fit ​​mechanism 58. The outer surface of the limiting plate 50 is fixedly installed on the inner surface of the side of the frame 4. A motor 51 is fixedly installed on the side surface of the limiting plate 50. A bidirectional lead screw 52 is fixedly sleeved at the output end of the motor 51. Limiting blocks 53 are threadedly connected to the outer surfaces of both ends of the bidirectional lead screw 52. The two limiting blocks 53 are symmetrically arranged, and the outer surfaces of their ends are slidably installed with the inner surface of the limiting plate 50. Two fixing rings 55 are fixedly sleeved at the end of the main rod 54 away from the second armor plate 57, and their outer surfaces are snap-fitted with the inner surfaces of the limiting blocks 53. The snap-fit ​​mechanism 58 is located inside the end of the main rod 54 away from the fixing ring 55.

[0029] The snap-fit ​​mechanism 58 includes a second motor 580, which is fixedly mounted on the surface of the end of the main rod 54. The output end of the second motor 580 is fixedly sleeved with a main gear 581. The outer edge of the main gear 581 is meshed with three driven gears 582. The middle of each of the three driven gears 582 is fixedly sleeved with a shaft, and a limiting piece 583 is fixedly mounted on the outer surface of the shaft. The outer surface of the limiting piece 583 is movably mounted to the inner surface of the end of the main rod 54.

[0030] By setting up the snap-fit ​​mechanism 58, the main gear 581 connected to the output end of the control motor 580 is rotated, which will drive the other three driven gears 582 meshing on the outer edge to rotate, so that the limiting plate 583 connected by the shaft rod is deflected and moved against the inner wall of the end of the main rod 54 and retracted into the interior of the end of the main rod 54. At this time, the armor plate 56 is unlimited and can be removed along the surface of the main rod 54.

[0031] The base plate 1 has a drive motor 6 at its top, and a transmission mechanism 7 is fixedly connected to the output end of the drive motor 6. The inner surface of the top of the transmission mechanism 7 is fixedly connected to the outer surface of the connecting pipe 3. A cleaning mechanism 8 is provided on the left side of the base plate 1, and a dust box 9 is provided at the bottom of the cleaning mechanism 8.

[0032] The cleaning mechanism 8 includes a bracket 80, the side of which is fixedly installed on the surface of the fixing plate 2. A roller 81 is rotatably installed on the top of the bracket 80. Three electric telescopic rods 82 are fixedly installed on the inner surface of the side wall of the roller 81. The three electric telescopic rods 82 are arranged around the roller 81, and a brush plate 83 is fixedly installed at the end near the middle of the roller 81. A toothed ring 84 is fixedly sleeved on the outer surface of the end of the roller 81. A gear 85 meshes with the outer edge of the toothed ring 84. A transmission mechanism 86 is sleeved on the side end of the middle of the gear 85. The bottom end of the transmission mechanism 86 is fixedly sleeved with the output end of the drive motor 6.

[0033] By setting up transmission mechanism 7 and transmission mechanism 86, both of which are existing transmission devices composed of pulleys and tracks, the output end of drive motor 6 is connected to connecting pipe 3 and gear 85, effectively utilizing the same type of drive device.

[0034] The working process of this utility model is as follows:

[0035] When armoring the cable, it can be processed by passing it through the inside of the connecting pipe 3 to the armor forming area on the right side of the bottom plate 1. The steel strip used for processing is placed between the armor plate 1 56 and the armor plate 2 57, and its end passes through the movable roller of the limiting plate and the slot of the fixed plate 2 in the middle. The first end is then manually welded. After that, as the drive motor 6 drives the transmission mechanism 1 7 to pull the connecting pipe 3, frame 4 and other structures to rotate, and the cable is fed, the rotating steel strip is wrapped around the surface of the cable to achieve the armoring treatment of the cable surface.

[0036] Furthermore, when it is necessary to change the steel strip used for armor, the bidirectional lead screw 52 connected to the output end of the motor 51 can be controlled to rotate, pulling the limit blocks 53 connected by threads at both ends to slide along the inner surface of the limit plate 50 and move towards both ends of the limit plate 50, moving away from each other. At this time, the end of the main rod 54 with the fixing ring 55 is released from the state of being clamped and limited by the two abutting limit blocks 53, so that the main rod 54 and the armor plate 56 fixed on the outer surface can be removed from the side of the frame 4 to facilitate the replacement of steel strips of different specifications. In addition, the armor plate 56 can be disassembled separately using the snap-fit ​​mechanism 58, which facilitates the loading operation after the steel strip coil is used.

[0037] During cable feeding, the cable can first pass through the inside of the roller 81 and then out through the inside of the connecting pipe 3. While inside the roller 81, the electric telescopic rod 82 is extended, pushing the end-connected electric telescopic rod 82 to fit against the surface of the cable. Simultaneously, as the subsequent drive motor 6 drives the transmission mechanism 7 to rotate the connecting pipe 3, the transmission mechanism 86 connected to the output end of the drive motor 6 drives the gear 85 to rotate synchronously. This causes the meshing gear ring 84 to drive the roller 81, which is fixedly sleeved in the middle, to rotate along the inner wall of the bracket 80, brushing away the dust on the cable surface and collecting it inside the dust box 9, thereby maintaining the flatness of the cable surface and improving the quality of subsequent armoring.
