Cable ground laying protection device

Abstract

The present invention provides a cable ground laying protection device, comprising a base, a cover board and an articulated shaft. The base is an integrated part with a trapezoidal section; the base is provided with a lower end face, side end faces, inclined planes and upper end faces; the numbers of the side end faces, the inclined planes and the upper end faces respectively are 2; the lower ends of the two inclined planes are connected with the lower end face by the two side end faces; the upper ends of both the left and right inclined planes are integrally connected with the outer ends of both the left and right upper end faces; a sunk connecting face is horizontally formed between both the left and right upper end faces; cable troughs which are concave from top to bottom of the connecting face are formed on the base and a supporting edge is formed by a bulge between each two adjacent cable troughs; two connecting blocks are respectively arranged at the front parts of both left and right sides of the base; two connecting grooves are formed at the rear parts of both the left and right sides of the base; and the cover board is articulated to the base by the articulated shaft in an openable manner. The cable ground laying protection device has a simple structure, is easy to carry, is convenient and rapid to connect and assembly on site and can effectively resist to a heavy pressure of smaller than 25 tons when in use.

Description

technical field [0001] The invention relates to an auxiliary tool for laying electric cables, in particular to a protective device for laying cables on the ground. Background technique [0002] The power supply department often needs to pass the cable from the ground through the road or street for construction during the operation process of pulling new cables and setting bypass cables for line or equipment maintenance; if the cables are directly laid on the road or street, the traffic People and vehicles need to cross or roll over the cables on the road, so that there are huge safety hazards in the operation process. Therefore, protective devices must be used for cables temporarily crossing the road or street from the ground to protect the personal safety of relevant personnel. Safety and safe operation of cables and related equipment.

[0002] The power supply department often needs to pass the cable from the ground through the road or street for construction during the operation process of pulling new cables and setting bypass cables for line or equipment maintenance; if the cables are directly laid on the road or street, the traffic People and vehicles need to cross or roll over the cables on the road surface, so that there are huge safety hazards in the operation process. Therefore, protective devices must be used for cables temporarily crossing the road or street from the ground to protect the personal safety of relevant personnel. Safety and work safety on cables and related equipment

[0003] Common protection devices for cables temporarily passing through roads or streets, such as the Chinese patent document CN203056520U, which discloses a road transition cable protection device, which adopts a trapezoidal cross-section and a trough installed in the trough. The rubber snap ring used to fix the cable has the following disadvantages: it is not clear how to connect the protection devices, the cable setting is inconvenient, and only one cable can be installed, and the structure is not strong enough to withstand heavy pressure; another example is the authorized announcement number: The Chinese patent document of CN204376348U, it discloses a kind of passing cable protection device, and this device structure is very simple, for the high voltage cable of power supply department, its security obviously can't meet the requirement; Other common cables pass through road or street temporarily The rated load capacity of the protective device is usually only 10 tons. However, according to GB1589 "Road Vehicle Outline Dimensions, Axle Load and Quality Limitations", the maximum allowable total mass of the three-axle truck in the car category is 25 tons. The maximum allowable total mass of the two-axle trailer (each axle and each side is double tires) is 20t. If a truck of more than 20 tons that meets the national standard passes through this type of cable protection device, it will be unbearable, and the protection device will lose its protection. Function thus seriously threatens the safety of passing cables, brings serious safety hazards and even causes accidents
