Abstract

The utility model discloses a bridge horizontal cross including a groove frame and a protective cover, the protective cover is movably connected with the groove frame, the groove frame is integrally arranged in a cross shape, every two openings of the groove frame are connected through a chamfering, the center position of the groove frame is provided with four symmetrically arranged air pipes, a passage is arranged between every two air pipes, and the four air pipes are combined to form a cylinder, the air pipes are vertical to the bottom plate of the groove frame, the groove frame bottom plate at the connection parts of the air pipes and the protective cover are provided with through holes consistent to the cross section of the air pipes, and the side plates at the two sides of a port of the groove frame are provided with connecting holes. The bridge horizontal cross, being simple in structure, prevents a cable from excessive bending during the laying direction of the cable, and the heat radiation performance of cable convergent parts is good because of the arrangement of the air pipes, and the service life of the cable is prolonged.

Description

The horizontal four-way of a kind of crane span structure

Technical field

The utility model relates to the connection of crane span structure, particularly the horizontal four-way of a kind of crane span structure.

Background technology

During cable laying, often can need to use four-way; the plane of current four-way in opening junction is all right angle face mostly; like this in cable laying break-in; the corner angle of junction can make cable be 90 ° of bendings; easily cause the wearing and tearing of cable; and because camber is excessive, the situation that very easily causes cable internal wire to fracture, has affected life-span of cable to a certain extent.

Utility model content

For making up the deficiencies in the prior art, the utility model provides a kind of crane span structure horizontal four-way.

The technical scheme that the utility model adopts:

The horizontal four-way of a kind of crane span structure, comprise truss and protective cover, protective cover is movably connected on truss, described truss integral body is cross, between every two openings of described truss, by chamfering, connect, at the center position of truss, be provided with four air pipes of symmetric arrays, between described every two air pipes, be provided with passageway, and it is a cylinder that four air pipes are pieced together, described air pipe is perpendicular to truss base plate, and be to be equipped with the through hole consistent with air pipe cross section on the truss base plate of air pipe joint and protective cover, on the side plate of the both sides, port of truss, be equipped with connecting hole.

Advantage of the present utility model:

The utility model is simple in structure, cable overflexing while having avoided cable laying break-in, and the setting of air pipe to make cable converge place's thermal diffusivity good, increased useful life of cable.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

As shown in Figure 1, the horizontal four-way of a kind of crane span structure, comprise truss 1 and protective cover, described truss integral body is cross, protective cover is movably connected on truss, between every two openings of described truss, by chamfering 2, connect, at the center position of truss, be provided with four air pipes 3 of symmetric arrays, between described every two air pipes, be provided with passageway 4, and it is a cylinder that four air pipes are pieced together, described air pipe is perpendicular to truss base plate, and be to be equipped with the through hole consistent with air pipe cross section 5 on the truss base plate of air pipe joint and protective cover, on the side plate of the both sides, port of truss, be equipped with connecting hole.

Claims

1. the horizontal four-way of crane span structure, it is characterized in that: comprise truss and protective cover, protective cover is movably connected on truss, described truss integral body is cross, between every two openings of described truss, by chamfering, connect, at the center position of truss, be provided with four air pipes of symmetric arrays, between described every two air pipes, be provided with passageway, and it is a cylinder that four air pipes are pieced together, described air pipe is perpendicular to truss base plate, and be to be equipped with the through hole consistent with air pipe cross section on the truss base plate of air pipe joint and protective cover, on the side plate of the both sides, port of truss, be equipped with connecting hole.
