Description

Technical Field

[0001] The utility model relates to the technical field of cable protection pipes, and particularly relates to a strengthened inner wall structure of a PE cable protection pipe. Background Technique

[0002] A cable is usually made of one or more mutually insulated conductors and an outer insulating protective layer, and is a wire for transmitting electricity or information from one place to another. There are power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single-stranded or multi-stranded wires and insulating layers, and are used to connect circuits, electrical appliances, etc. To protect the safe use of the cable, a cable protection pipe is required. The cable protection pipe, also known as a cable duct and a power cable duct, is mainly installed in the section where the communication cable crosses the power line to prevent the power line from breaking and causing a short-circuit accident, causing the communication cable and the steel wire rope to be electrified, so as to protect the cable and even the whole machine from being burned out; however, the cable protection pipes used at present have a single function, and most of them are pipes made of a single layer of material. When the pipe is squeezed, it is easy to deform and cause the pipe to rupture. Moreover, the inside of the cable protection pipe is generally designed with a single cavity. When inserting cables, multiple cables are combined together and cannot be inserted separately, making it difficult to meet different protection requirements. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a strengthened inner wall structure of a PE cable protection pipe, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0018] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0019] As Figures 1-4 shown, a reinforced inner wall structure of a PE cable protection pipe includes a cable protection pipe body 1. A silicate heat insulation soft pad 2 is fixedly installed on the inner surface of the cable protection pipe body 1. A reinforcement structure 3 is arranged inside the cable protection pipe body 1. The reinforcement structure 3 includes a rectangular column 301, a rotating block 302, a docking groove 303, a docking block 304, a transmission rod 305, a first bearing 306, a bevel gear 307, a bevel gear groove 308, a rectangular groove 309, a second bearing 310, a rectangular sleeve 311, a threaded rod 312, a telescopic column 313, an arc-shaped support plate 314, and a partition plate 315;

[0020] A rectangular groove 309 is opened inside the rectangular column 301. First bearings 306 are fixedly installed in the middle of the front and rear surfaces of the rectangular groove 309. A transmission rod 305 is movably installed on the inner surface of the first bearing 306. A rotating block 302 is fixedly installed at the front end of the transmission rod 305; a docking groove 303 is opened on the front surface of the rotating block 302. A docking block 304 is fixedly installed on the rear surface of the transmission rod 305. Bevel gears 307 are fixedly installed on the outer surface of the transmission rod 305 near both ends; rectangular sleeves 311 are fixedly installed on the four sides of the outer surface of the rectangular column 301 near the front and rear ends. A second bearing 310 is fixedly installed on the top surface of the rectangular sleeve 311. A threaded rod 312 is movably installed on the inner surface of the second bearing 310; a bevel gear groove 308 is opened at the upper end of the threaded rod 312. The bevel gear groove 308 opened at the upper end of the threaded rod 312 meshes with the bevel gear 307. A telescopic column 313 is slidably installed inside the rectangular sleeve 311; the telescopic column 313 is helically installed on the outer surface of the threaded rod 312. An arc-shaped support plate 314 is fixedly installed on the lower surface of the telescopic column 313. Partition plates 315 are fixedly installed on the four sides of the rectangular column 301. When in use, the rectangular column 301 can be placed into the cable protection pipe body 1, and then the rectangular column 301 is rotated to make the telescopic column 313 extend in the rectangular sleeve 311, driving the arc-shaped support plate 314 to move until it is in close contact with the silicate heat insulation soft pad 2 fixedly installed on the inner surface of the cable protection pipe body 1, strengthening the support for the cable protection pipe body 1 and preventing the pipe from being easily deformed and cracked when being extruded. Moreover, through the partition plate 315, the internal space of the cable protection pipe body 1 can be divided into multiple cable cavities, facilitating the separate insertion of multiple strands of cables.

[0021] It should be noted that the present utility model is a reinforced inner wall structure of a PE cable protection pipe. When in use, the rectangular column 301 is placed into the cable protection pipe body 1, and then the rectangular column 301 is rotated, causing the rectangular column 301 to drive the transmission rod 305 to rotate on the inner surface of the first bearing 306, and causing the umbrella-shaped gears 307 fixedly installed near both ends on the outer surface of the transmission rod 305 to rotate. Since the umbrella-shaped tooth grooves 308 opened at the upper end of the threaded rod 312 are engaged with the umbrella-shaped gears 307, the threaded rod 312 is driven to rotate on the inner surface of the second bearing 310, causing the telescopic column 313 spirally installed on the outer surface of the threaded rod 312 to extend in the rectangular sleeve 311, driving the arc-shaped support plate 314 to move until it is in close contact with the silicate heat insulation soft pad 2 fixedly installed on the inner surface of the cable protection pipe body 1 of the cable protection pipe body 1, strengthening the support for the cable protection pipe body 1, preventing the pipe from being easily deformed when being extruded and causing the pipe to rupture. Moreover, through the partition plate 315, the internal space of the cable protection pipe body 1 can be divided into multiple cable cavities, facilitating the separate insertion of multiple strands of cables.
