Outdoor cable and processing method thereof

Abstract

The invention relates to the technical field of cable processing, in particular to an outdoor cable and a processing method thereof. When construction activities such as municipal construction, pipeline laying, road maintenance and the like of road surface excavation need to be carried out subsequently in an underground cable laying area, an outer armor layer of a cable is easily damaged due to too deep excavation operation or wrong position. In order to avoid the problem, the sheaths with the jacks are distributed on the cable, and the two ends of the metal rib with the two ends directly bent leftwards are inserted into the jacks of the two adjacent sheaths respectively, so that the metal rib protrudes out of the cable and replaces the cable to make contact with the excavation structure, and the rigid material plays the roles of tactile feedback and cable protection. Meanwhile, the prefabricated part sheaths, the ribs and the like which are simple in structure are low in cost, high in production speed and capable of being assembled in advance, and on-site construction time is shortened.

Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and more particularly to an outdoor cable and a processing method thereof. Background Art

[0002] In the field of cable laying, there are various construction methods for outdoor cables, and the selection is often based on a comprehensive consideration of multiple factors such as the specific construction environment, cable type, cost budget, and long-term maintenance requirements. Among them, direct burial is a common construction method.

[0003] However, the direct underground cable construction method is not without flaws. A significant problem is that when the underground cable laying area needs to carry out subsequent construction activities such as municipal construction, pipeline laying, road maintenance, etc., the excavation work is too deep or in the wrong position, which can easily damage the outer armor of the cable. There is still room for improvement in how to ensure the efficiency and economy of cable laying while effectively avoiding damage to the cable outer armor in the case of possible construction sections. Summary of the invention

The upper end of the wiping block is open, and a channel communicating with the opening is arranged on the wiping block.

[0012] The wiping block has a built-in sponge, and the upper end surface of the sponge is not lower than the upper end surface of the wiping block.

[0013] A roller mechanism is arranged on the right side of the wiping block, and a limiting mechanism is arranged between the wiping block and the roller mechanism.

DETAILED DESCRIPTION

[0029] An outdoor cable processing device is used to process an outdoor cable. The outdoor cable includes a cable 1. At least two sheaths 2 are provided on the cable 1. Adjacent sheaths 2 form a group. Two vertical plug holes 3 are provided on the front and rear sides of each sheath 2. The four plug holes 3 are respectively located at the four corners of a virtual square. The cable 1 is located between the front and rear rows of plug holes 3. During construction, the sheath 2 is lowered into a tunnel with the cable 1. Ribs 4 with both ends bent downward are used to reinforce the front and rear sides above the cable 1. Specifically, the two ends of the rib 4 are respectively inserted into two adjacent sheaths 2. For example, two adjacent plug holes 3 located at the rear side of two adjacent sheaths 2 are inserted into the two downward ends of a rib 4, and the bottom of the rib 4 is supported on the ground, and the top of the rib 4 is higher than the cable 1. Similarly, a rib 4 is also inserted into the front side of the cable 1 in the two adjacent plug holes 3 located at the front side of two adjacent sheaths 2.

[0030] The outdoor cable processing device includes a belt conveyor, which includes a frame 5, and the left and right ends of the frame 5 are each rotatably connected to a roller, and the front ends of the two rollers are each fixedly connected to a pulley, and the two pulleys are sleeved with a belt to achieve synchronous rotation. The two rollers are sleeved with a conveyor belt 6, and the roller on the left is fixedly connected to the output shaft of the first motor 7, and the first motor 7 is fixedly connected to the frame 5. Starting the first motor 7 is used to rotate the conveyor belt 6 clockwise. The sockets 3 of the sheath 2 face upward, and are placed on the conveyor belt 6 in a single row in the left and right directions. The front and rear ends of the conveyor belt 6 are fixedly connected with flanges to limit the sheath 2 and keep the sockets 3 of the sheath 2 facing upward.

[0031] A guide rail 8 parallel to the belt conveyor is arranged above the belt conveyor, and a traveling mechanism capable of moving along the guide rail 8 is installed on the guide rail 8. The traveling mechanism includes a slider 9 slidably connected to the guide rail 8, a second motor 10 is fixedly connected to the slider 9, a wheel 11 is fixedly connected to the output shaft of the second motor 10, and the second motor 10 is used to drive the wheel 11 to rotate, so that the gripping force generated when the wheel 11 rolls on the upper end surface of the guide rail 8 drives the slider 9 to move along the guide rail 8, and a first telescopic cylinder 12 is fixedly connected to the lower end of the slider 9, the movable end of the first telescopic cylinder 12 is arranged downward, and the movable end of the first telescopic cylinder 12 is fixedly connected to the base 13.

[0032] An actuator is installed at the bottom of the traveling mechanism. The actuator includes a base 13 fixed to the lower end of the movable end of the first telescopic cylinder 12. The lower end of the base 13 is fixed to the third motor 14. The output shaft of the third motor 14 is fixed to a friction wheel 15 and a brake column 16. The brake column 16 is higher than the friction wheel 15. The lower end surface of the brake column 16 can contact the upper end surface of the sheath 2, and the friction wheel 15 is used to contact the cable 1. There are multiple actuators in the left and right directions, each corresponding to a sheath 2. The first telescopic cylinder 12 is used to drive the friction wheel 15 to descend. After the friction wheel 15 on the far right is descended and rotated clockwise, it is used to drive the cable 1 to move leftward on the stopped conveyor belt 6 to enter the sheath 2 along the chamfered surface of the inner edge of the sheath 2, and the brake column 16 is used to maintain the relative position of the sheath 2. When the cable 1 passes through the sheath 2 from right to left and approaches the second sheath 2, the friction wheel 15 of the next actuator on the left side is lowered to contact the cable 1, so that the brake column 16 presses the second sheath 2, thereby using the two friction wheels 15 to transport the cable 1 into the second sheath 2. As the number of cables 1 entering the sheath 2 increases, the number of friction wheels 15 driving the cables 1 also increases.

[0033] It also includes a second telescopic cylinder 17 arranged on the right side of the belt conveyor, and a wiping block 18 is fixedly connected to the telescopic end of the second telescopic cylinder 17.

[0034] If water is used, a sponge built into the wiping block 18 can be used, with the upper end surface of the sponge not lower than the upper end surface of the wiping block 18, and the outer skin of the cable 1 can be moistened by wiping.

[0035] A roller mechanism 19 is provided on the right side of the wiping block 18, and the cable 1 is rolled up or released by rotating the roller structure. A limiting mechanism 20 is provided between the wiping block 18 and the roller mechanism 19. The limiting mechanism 20 limits the height of the cable 1 by means of upper and lower guide wheels. Each guide wheel is provided with a groove, thereby limiting the freedom of the cable 1 in the front and rear directions.
