Description

Wire installation device

Technical Field

The invention relates to a cable accessory, in particular to an electric wire installation device.

Background

When construction is performed on a construction site, since many devices requiring power consumption are provided and the positions of temporary power consumption are random, the power supply and the power consumption may be positioned at both ends of a passage or a road surface, and thus temporary wiring may be laid on the road surface. When going to shallow, workman, construction vehicle pass through this highway section, can play to hang or roll the electric wire of laying on the road surface, long-time dragging or roll the electric wire and can lead to broken string or electric leakage.

A general method for solving this problem is to erect the electric wire in the air to avoid contact with workers or vehicles, but it is too costly to specially set up the electric pole for a temporary construction site. In the prior art, a structure similar to a bridge arch is laid on a road surface, a cable passes through a bridge opening below the bridge arch structure, and external force from workers and vehicles is supported by the bridge arch structure. The bridge arch structure has the problems that: the steel structure is large in load, can be used for a long time, but is high in cost and difficult to carry. The bridge arch structure made of plastic materials is convenient to carry and low in cost, but has the problems of small load and easiness in damage.

Disclosure of Invention

The invention provides a wire mounting device with larger load and long service life, aiming at solving the problem that the bridge arch structure of the existing plastic protection wire is small in load and easy to damage.

The basic scheme provided by the invention is as follows: the electric wire installation device comprises a bridge arch structure, wherein the bridge arch structure comprises a base and a cover plate, the cross section of the base is trapezoidal, a cable installation groove for installing an electric wire is formed in the upper end face of the base, the cover plate is hinged to the upper end face of the base, the electric wire installation device also comprises a fluid frame, the bridge arch structure is arranged in the fluid frame, the fluid frame comprises a frame body, a front baffle plate and a rear baffle plate, the front baffle plate is hinged to the front end of the frame body, a torsion spring is arranged between the front baffle plate and the frame body, the rear baffle plate is hinged to the rear end of the frame body, and the torsion spring is arranged; shear thickening fluid is contained in the fluid frame, an elastic film covers the surface of the shear thickening fluid, and a plurality of layers of stable nets made of fiber materials are paved in the shear thickening fluid.

The working principle is as follows: the scheme has two states for two situations: a lightweight, slow object is pushed over the wire mounting device, such as a manually propelled cart. The base of the structure of the bridge arch is matched with the cover plate to support the trolley passing through the upper part. The fluid frame and the shear thickening fluid in the fluid frame do not work at the same time, and people and the cart cannot be prevented from passing through the fluid frame and the shear thickening fluid.

Secondly, when an object with large weight and high speed passes through the electric wire installation device, for example, when a loaded motor vehicle passes through, the tire of the motor vehicle firstly impacts the front baffle of the fluid frame, the front baffle is hinged on the frame body, so the front baffle can freely rotate, the rotating front baffle impacts the shear thickening fluid in the fluid frame, the viscosity of the shear thickening fluid subjected to high-speed impact is sharply improved and even approaches to solid, the tire climbs along the inclined front baffle and the solidified shear thickening fluid subjected to impact, then passes through the upper end face of the shear thickening fluid and passes through the upper part of the bridge arch structure, in the process, the shear thickening fluid is subjected to high-speed impact of the tire, the whole approach solidification is realized, most of impact is absorbed and loaded, and only a small part of impact energy is transmitted to the bridge arch structure. And is transferred to the bridge arch mechanism as a whole with a large contact area. This greatly reduces the impact of vehicles passing at high speed on the bridge arch structure. After the vehicle passes, the front and rear fenders rebound under the action of the torsion spring to re-block the shear thickening fluid. Shear thickening fluids self-flow to a recovery level in the absence of external impact. The elastic film can prevent the shear thickening fluid from flowing out from the gaps between the front baffle plate, the rear baffle plate and the frame body.

Compared with the prior art, the scheme has the advantages that: 1. the lower plastic material of convenient transport and cost can be adopted to the bridge arch structure in this scheme because the condition of being loaded by the bridge arch structure is when pressing electric wire installation device by light in weight, slow object, and the fluid frame also conveniently shifts with the shear thickening fluid of loading in the fluid frame.

2. When meeting heavy, and when the fast object rolled over electric wire installation device, made shear thickening fluid structure become the characteristic of solid from liquid with the help of strong impact, the buffering object can effectual extension bridge arch structure's life to installation device and bridge arch structure's impact.

3. Compare on the tire directly rolls in to the bridge arch structure, when the heavy object rolled installation device in this scheme, the impact can distribute more evenly, and the area of bridge arch structure atress is bigger, and the atress is more even.

4. After impact, the shear thickening fluid can automatically level under the restriction of the fluid frame under the action of the lost external force, and the self-repairing effect can be achieved.

Scheme II: for the preferred of basic scheme, the up end of fluid frame is equipped with the reinforcement, and the reinforcement includes floating platform, elasticity hits beater plate and torsional spring, and the floating platform sets up in the stable net of the superiors, and elasticity hits the beater plate and installs on the floating platform, and the floating platform is connected to torsional spring one end, and the other end is connected elasticity and is hit the beater plate, and the torsional spring makes elasticity hit beater plate and the angle of horizontal plane equal to 90. Has the advantages that: shear thickening fluid has the characteristic that receives strong impact viscosity just can sharply improve, has set up the reinforcement for the reinforcing to shear thickening fluid's impact, when the tire strikes the board from the root, strikes the board and can strike shear thickening fluid's surface with the speed faster than the tire to reach the purpose of high-speed impact shear thickening fluid, make shear thickening fluid viscosity stronger, avoid leading to the bridge arch structure to receive extra extrusion because of the impact of tire is not enough.

The third scheme is as follows: preferably, the lower end surface of the fluid frame is provided with a friction bulge. Has the advantages that: the friction bulge can ensure that the fluid frame is more stably fixed on the ground.

And the scheme is as follows: preferably, the fluid frame is provided with a liquid outlet valve. Has the advantages that: before the fluid frame is carried, the shear thickening fluid is discharged into a container for transportation through a liquid outlet valve, so that the device is convenient to mount and integrally transfer.

And a fifth scheme: preferably, a waterproof rubber pipe is arranged in the cable installation groove, and two ends of the waterproof rubber pipe are both bonded to the fluid frame. Has the advantages that: shear thickening fluid is the fluid when no external force, probably flows into in the bridge arch structure, flows out from the gap of electric wire and cable mounting groove, and water-stop rubber tube possesses certain elasticity, can avoid shear thickening fluid to flow out with the gap jam between electric wire and the cable mounting groove.
