Abstract
The utility model discloses a kind of bridge rotating steel ball hinge relay thrustor, comprise revolving body, revolving body is supported on basis by steel ball free bearing, basis is provided with traction counter-force seat, pull rope is provided with between revolving body and described traction counter-force seat, the soffit of revolving body is provided with spike, bracket, basis upper surface is respectively equipped with counter-force seat in the both sides of the rotary track of spike, be provided with pushing tow support between two counter-force seats that the both sides of rotary track are relative, between pushing tow support and bracket, be provided with force application apparatus.When bridge rotating meets jam, relay can complete rotator construction, solve when existing highway bridge is turned and occur that jam cannot complete the problem of turning smoothly.
Description
Technical field
The utility model relates to a kind of Bridge Rotation Construction Technique equipment, particularly relates to a kind of bridge rotating steel ball hinge relay thrustor.
Background technology
At present, in bridge construction by swing, bridge rotating generally forms couple by force on two traction counter-force seats and completes bridge rotating.Turn in carrying out, if there is friction pair jam, be difficult to complete Bridge Rotation Construction Technique operation smoothly.
Summary of the invention
The purpose of this utility model is to provide a kind of when bridge rotating meets jam, and energy relay completes the bridge rotating steel ball hinge relay thrustor of rotator construction.
The purpose of this utility model is achieved through the following technical solutions:
Bridge rotating steel ball hinge relay thrustor of the present utility model, comprise revolving body, described revolving body is supported on basis by steel ball free bearing, described basis is provided with traction counter-force seat, pull rope is provided with between described revolving body and described traction counter-force seat, the soffit of described revolving body is provided with spike, described spike is provided with bracket along the side of its rotary track, described basic upper surface is respectively equipped with counter-force seat in the both sides of the rotary track of described spike, pushing tow support is provided with between two counter-force seats that the both sides of rotary track are relative, force application apparatus is provided with between described pushing tow support and described bracket.
The technical scheme provided as can be seen from above-mentioned the utility model, the bridge rotating steel ball hinge relay thrustor that the utility model embodiment provides, soffit due to revolving body is provided with spike, bracket, basis upper surface is respectively equipped with counter-force seat in the both sides of the rotary track of spike, pushing tow support is provided with between two counter-force seats that the both sides of rotary track are relative, force application apparatus is provided with between described pushing tow support and bracket, when bridge rotating meets jam, relay can complete rotator construction, solve when existing highway bridge is turned and occur that jam cannot complete the problem of turning smoothly.

Detailed description of the invention
To be described in further detail the utility model embodiment below.
Bridge rotating steel ball hinge relay thrustor of the present utility model, its preferably detailed description of the invention be:
Comprise revolving body, described revolving body is supported on basis by steel ball free bearing, described basis is provided with traction counter-force seat, pull rope is provided with between described revolving body and described traction counter-force seat, the soffit of described revolving body is provided with spike, described spike is provided with bracket along the side of its rotary track, described basic upper surface is respectively equipped with counter-force seat in the both sides of the rotary track of described spike, be provided with pushing tow support between two counter-force seats that the both sides of rotary track are relative, between described pushing tow support and described bracket, be provided with force application apparatus.
The multiple spike of soffit circumference uniform distribution of described revolving body and bracket.
Described basic upper surface is provided with many group counter-force seats in the both sides of the rotary track of described spike.
Bridge rotating steel ball hinge relay thrustor of the present utility model, when bridge rotating meets jam, relay can complete rotator construction, solve when existing highway bridge is turned and occur that jam cannot complete the problem of turning smoothly.
Specific embodiment:
As shown in Figure 1, Figure 2, Figure 3 shows, relay thrustor comprises spike, bracket, pushing tow support, force application apparatus etc.Set up bracket mechanism in spike rotary track end positions, both can adopt welding or other connected modes.Force application apparatus is arranged between pushing tow support and spike bracket.Pushing tow support rests on adjacent two the counter-force seats of Internal and external cycle.When there is jam in bridge rotating process, can by means of the relay pushing tow of the relay thrustor rationally fallen between spike bracket and counter-force seat, realize bridge and turn smoothly and put in place.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
