Embodiment 1

[0028] Such as figure 1 , 2 As shown, a construction cable protector of the present invention includes a housing 1, a first connecting piece 3, a second connecting piece 2, and a breaking piece 4, and the first connecting piece 3 and the second connecting piece 2 are pulled The breaking piece 4 is connected, and the housing 1 is sleeved outside the breaking piece 4, the first connecting piece 3, the second connecting piece 2, and the breaking piece 4. When the breaking piece 4 is broken, the casing 1 bears the first The tension between the connecting piece 3 and the second connecting piece 2.

[0029] A buffer chamber 5 is provided between the first connecting piece 3 or the second connecting piece 2 and the housing 1, and a small hole 6 communicating with the outside of the housing 1 is provided on the side wall of the buffer chamber 5; After being pulled off, the first connecting piece 3 or the second connecting piece 2 squeezes the buffer chamber 5 to drain or exhaust the...

Embodiment 2

[0035] In the structure of embodiment 1, a paint bag and a solvent bag are respectively housed in the buffer cavity 5, the paint bag and the solvent bag are all made of elastic capsules as containers, air and pigment are housed in the paint bag, gasoline, paint, etc. are housed in the solvent bag. The pigment in the bag is composed of the following powders by weight: 30-50 parts of cinnabar, 40-50 parts of 300 mesh ground calcium carbonate, 20-30 parts of red coral, 15-22 parts of polyoxyethylene oleate, 16-33 Parts of polyethylene wax, 40-50 parts of luminous powder, 33-45 parts of garnet, 10-30 parts of hematite, 3-9 parts of nano-silver powder, 1-9 parts of zoisite, 11-16 parts of sanidine , 13-19 parts of heulandite, 15-25 parts of crocoite, 17-19 parts of red shale, 16-17 parts of sodium amphibole, and 16-18 parts of graphite.

Embodiment 3

[0037]In the structure of embodiment 1, the second connector 2 and the first connector 3 are respectively connected with the cable, and the cable is composed of a coaxial inner core, a middle layer, and an outer layer from the inside to the outside, and the production method of the cable is as follows:

[0038] Step 1: Use steel wires, titanium alloy wires, and tin wires to arrange and mix them in parallel to form an inner core group, and then extrude the inner core group in an environment higher than the melting point of the tin wire, and then cool the inner core group to obtain the inner core group. core;

[0039] Step 2: The middle layer is composed of nylon wire, carbon steel wire, and boron-iron alloy wire; first, the carbon steel wire is arranged on the outside of the nylon wire in a direction parallel to the inner core, and then the nylon wire is spirally wound and the carbon steel wire and the nylon wire are woven into one; Then multiple parallel boron-iron alloy wires...

Abstract

The invention relates to a device for observing overpressure of a mooring rope for constructional engineering, belongs to the field of buildings, and particularly relates to a mooring rope protector for a building. The mooring rope protector for the building comprises a shell, a first connecting piece, a second connecting piece and a snapping piece, wherein the first connecting piece is connected with the second connecting piece through the snapping piece; the shell sleeves the outsides of the first connecting piece, the second connecting piece and the snapping piece; and after the snapping piece is snapped off, the shell bears a tensile force between the first connecting piece and the second connecting piece. By the design of the snapping piece which can be snapped off, use safety of the mooring rope can be guaranteed effectively, before the tensile force reaches a rated snapping-off force of the mooring rope, the snapping piece is snapped off at first, then whether the mooring rope is used in an overload manner can be observed effectively, and the protective feature of the mooring rope is improved. By the design of a weak link arranged on the mooring rope, whether the mooring rope is in an overpressure state or not when used can be judged, and therefore, the service life of the mooring rope in a using process can be judged.

Description

technical field [0001] The invention relates to a cable overpressure observation device for construction engineering, which belongs to the field of construction, in particular to a cable protector for construction. Background technique [0002] The steel wire rope is a spiral steel wire bundle twisted together with steel wires whose mechanical properties and geometric dimensions meet the requirements according to certain rules. The steel wire rope is composed of steel wire, rope core and lubricating grease. The steel wire rope is first twisted into strands by multi-layer steel wires, and then twisted into a helical rope by a certain number of strands with the rope core as the center. In material handling machinery, it is used for lifting, pulling, tensioning and carrying. The steel wire rope has high strength, light weight, stable operation, and is not easy to break suddenly, and the operation is reliable. The steel wire rope needs to withstand alternating loads during its...
