Description

Auxiliary device for laying cables in horizontal bridge

technical field

The utility model relates to cable laying technology, in particular to an auxiliary device for laying cables in a horizontal bridge frame.

Background technique

In large-scale building construction, the laying of cables is a project with a lot of work. On professional construction sites, cables are usually laid in bridges, which are standardized, tidy, and easy to maintain. The cross-section of the bridge frame is "U"-shaped, and the cables are laid in the "U"-shaped groove. Before the cables are laid, the bridge frame is fixed on the wall or the roof through the bracket. Bridges are divided into horizontal bridges and vertical bridges. When laying cables on horizontal bridges, first pass one end of the cable through the bridge along the wire groove, and then pull the passing end manually to finally lay the cable in place. This cable laying process has at least the following deficiencies: 1. Since the cable is directly pulled through the bridge, the length of the bridge generally has a length of 20-60 meters. Sliding friction, the contact area between the cable and the bottom of the bridge frame is large, and the rubber skin covered by the cable has a large friction coefficient, so the friction force is very large, and a large force is required to pull it. When pulling, it often takes several people to complete the laying task. , so the efficiency is low and the labor cost is high; 2. Because the friction between the cable and the bridge frame is very large, the rubber skin of the cable is easily worn out during the pulling process, thereby damaging the cable.

Utility model content

In view of the above-mentioned deficiencies in the prior art, the purpose of this utility model is to provide an auxiliary device for laying cables in a horizontal bridge frame that saves labor and is not easy to damage the cables.

In order to achieve the above object, the technical solution adopted by the utility model is as follows: an auxiliary device for laying cables in the horizontal bridge frame. The limiting plate stuck outside the two side walls of the bridge frame.

Both ends of the roller are respectively provided with radial through holes, and bolts pass through the radial through holes, and the bolts are locked on the roller through nuts, and the two limiting plates are located inside the bolts.

There are 2-4 radial through holes at each end of the roller, and one bolt is arranged in one of the radial through holes.

The radial through holes are arranged along the length direction of the roller shaft to form strip-shaped holes.

Rubber pads are respectively arranged between the two limiting plates and the bolts.

The distance between the insides of the two limiting plates is 25-40 mm larger than the distance between the outsides of the two side walls of the bridge frame.

Compared with the prior art, the utility model has the following beneficial effects:

1. Labor-saving laying. The sliding friction during laying is changed to rolling friction, so the construction intensity can be greatly reduced. The laying work that originally required the cooperation of multiple people can be completed by only one person after using this device, which not only saves labor costs, but also improves work efficiency.

2. Due to the reduced friction, the wear of the rubber skin of the cable is also greatly reduced, and the rubber skin will not be worn out, so the cable is not easily damaged during laying.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Fig. 1, it can be seen from the figure that the utility model is an auxiliary device for laying cables in a horizontal bridge frame. The limit plate 2 outside the two side walls of the bridge frame, the limit plate 2 is actually processed into a disc shape.

The two ends of the roller 1 are respectively provided with radial through holes 3, and the bolts 4 pass through the radial through holes 3, and the bolts 4 are locked on the roller 1 through the nuts 5, and the two limit plates 2 are located inside the bolts 4. , blocked by the bolt 4 to prevent the limit plate 2 from falling off from the two ends of the roller 1.

There are 2-4 radial through holes 3 at each end of the roller, as shown in Fig. 2, one bolt is arranged in one of the radial through holes and can be adjusted to another through hole as required, thereby adjusting The distance between the two bolts also determines the maximum distance between the two limiting plates, so that it can be applied to bridges of different widths.

The radial through hole 3 at each end of the roller shaft can also be only one and form a bar-shaped hole along the length direction of the roller shaft. See Figure 3. If the preceding multiple radial through holes are step-adjustable pitches, then this bar-shaped hole is equivalent to stepless adjustment. If the strength of the roller allows, the radial through holes at both ends of the roller can also be communicated to form a longer bar-shaped hole.

Rubber pads 6 are respectively provided between the two limiting plates 2 and the bolts 4 .

If the distance between the two limiting plates is too large, when the auxiliary device rests on the bridge and may deflect during use, it will affect the wiring. In view of this, the utility model sets the distance between the inner sides of the two limiting plates to be only 25-40 mm larger than the distance between the outer sides of the two side walls of the bridge. A certain gap prevents the rotation from being stuck, and there will be no deflection.

The utility model using method is as follows, see Fig. 4:

(1) Put the above-mentioned auxiliary device on the horizontal bridge frame 7 firstly. The two limiting plates 2 on the auxiliary device are located outside the two side walls 8 of the horizontal bridge frame. The distance between the limiting plate and the corresponding side wall of the horizontal bridge frame is 12-20 mm;

(2) Lay the cable 9 from one end of the horizontal bridge to the other end along the cable groove of the bridge. When passing through the auxiliary device, the cable 9 is supported by the roller 1 of the auxiliary device;

(3) When the cable passes over the roller, the cable can be pulled to make the roller rotate, and the cable can be routed in place during the rotation;

(4) After the wiring is in place, remove the auxiliary device so that the cable falls completely in the bridge frame to complete the final laying of the cable.

Because the bridge frame is fixed on the body of wall or the top plate by the bracket, the auxiliary device is located behind the bracket and rotates on the bracket when actually laying.

The above-mentioned embodiments of the utility model are only examples for illustrating the utility model, rather than limiting the implementation of the utility model. For those of ordinary skill in the art, other variations and modifications in various forms can be made on the basis of the above description. All the implementation manners cannot be exhaustively listed here. All obvious changes or variations derived from the technical solutions of the utility model are still within the scope of protection of the utility model.
