SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that the existing sleeve pipe structural stability is not enough for bridge cable that is used for municipal bridge engineering among the prior art, and the sleeve pipe for bridge cable that is used for municipal bridge engineering that proposes.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a sleeve for a bridge cable for municipal bridge engineering is designed, and comprises two semi-rings, wherein the two semi-rings are symmetrically arranged and fastened through bolts, two grooves are formed in one side of each of the two semi-rings, four grooves are uniformly formed, sliders are arranged in the four grooves in a sliding manner, connecting blocks are welded at one ends, far away from the semi-rings, of the four sliders, springs are arranged at one ends, opposite to one sides of the four connecting blocks, connecting plates are arranged at one ends, far away from the connecting blocks, of the four springs, two clamping plates are arranged at one sides, far away from the springs, two threaded rods are arranged at one sides, close to the springs, of the four connecting plates at intervals, eight threaded rods penetrate through the connecting plates and are respectively arranged on the eight clamping plates through bearings, clamping blocks are clamped in the four grooves.

Preferably, four the connecting plates outside the springs are all provided with sleeves, and the sleeves are in clearance fit with the connecting blocks.

Preferably, eight handles are installed at the top of the threaded rod, and eight anti-slip lines are arranged on the outer sides of the handles.

Preferably, the four clamping blocks are abutted to the four sliding blocks.

The utility model provides a bridge sleeve pipe for cable for municipal bridge engineering, beneficial effect lies in: this a bridge cable for municipal bridge engineering passes the bridge cable through the sleeve pipe, passes through the bolt fastening with two semi-rings, makes two semi-rings wrap up the sleeve pipe, rotates eight handles respectively, and eight handles drive the threaded rod respectively and rotate, makes the length of the threaded rod between connecting plate and the grip block, and the cooperation spring lets the inside sleeve pipe of grip block be in always and presss from both sides tight even atress clamping state, avoids the not enough condition of sleeve pipe structural stability for the bridge cable of municipal bridge engineering.
