A prior art patent document CN212230973U provides a cable protection device for building electrical engineering; the device is through setting up the roll mouth on the protection piece, roll mouth inner wall both ends set up main recess, roll mouth inner wall both sides set up the fixed block, set up vice recess in the fixed block, main recess, the cover is equipped with the base bearing respectively in the vice recess, the auxiliary bearing, the main shaft has been installed respectively to the drive roll, driven voller both ends, the auxiliary shaft, the drive roll, the driven voller is respectively through main shaft, the relative rotation of auxiliary shaft in the base bearing, the auxiliary bearing, make the cable at the drive roll, the cable transportation is laid on the driven voller, the wearing and tearing that cable and ground contact friction produced have been reduced.

Although the device has more beneficial effects, the following problems still exist: the device can't adjust two driven voller intervals, if two driven voller intervals are too big, when laying the cable, the cable can be in the drive roll upper end horizontal slip for cable stability is relatively poor, is not convenient for cable laying. In view of this, we propose a cable protection device for building electrical engineering.

Detailed Description

Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a cable protection device for building electrical engineering, includes

bottom plate

1, and 1 upper end of bottom plate rotates

installs drive roll

2, and 1 upper end left and right sides slidable mounting of bottom plate has curb plate 3, and two curb plates 3 rotate respectively to the terminal surface in opposite directions and install driven voller 4, and two curb plates 3 are fixed with the cover in opposite directions terminal surface and are located the peripheral protection piece 8 of drive roll 2.

Specifically, grooves 6 are formed in the front and rear sides of the upper end face of the bottom plate 1, threaded plates 10 connected with the grooves 6 in a sliding mode are fixed on the front and rear sides of the lower end face of the side plate 3, and threaded rods 7 in threaded fit with the threaded plates 10 are rotatably mounted in the grooves 6; the two side plates 3 can be driven to move towards or away from each other, and the distance between the two driven rollers 4 can be adjusted.
