Abstract
The utility model discloses a double-roller structure for a heat-insulating bracket. The double-roller structure comprises a first support plate and a second support plate arranged on the outside surface of a heat-insulating ring clamp; the double-roller structure is characterized in that a first roller shaft and a second roller shaft are arranged between the end parts of the first support plate and the second support plate, the first roller shaft and the second roller shaft are parallel to each other and located on a same horizontal plane; the first roller shaft and the second roller shaft are respectively provided with a first roller and a second roller which are same in structure. The double-roller structure for the heat-insulating bracket disclosed by the utility model is manufactured simply, locked by using a hexagon bolt, and convenient and rapid to install and remove; the double-roller structure can ensure that two points on a stressed surface are in contact with an externally sleeved steel pipe, so that the stressing is uniform and stable; the double-roller structure is small in friction force, so that the double-roller structure can pass through a weld by rolling smoothly without being clamped.
Description
Technical field
The utility model relates to a kind of sliding motion structure, especially a kind of two roller structures for heat-insulating bracket.
Background technique
The application form of direct burial steam conveying pipeline is mainly steel sleeve steel prefabricated thermal insulation pipeline; in, working pipe and outside protective pipe are steel pipe; in installation process, the simple heat-insulating bracket of normal employing is supported and is moved axially interior conduit; be generally guiding trestle or sliding support; on the junction plane of sliding floor and Steel Sleeve, pad teflon slide block reduces friction factor; because it is the face contact slide, frictional force and noise are larger.Because outer sleeve is spiral welded steel pipe, steel pipe inner wall has weld seam in addition, and weld seam can easily cause heat-insulating bracket with weld seam rotation or stuck by weld seam higher than bottom surface 2-3mm, affects pipeline and moves, and even may cause the torsional deformation of pipeline.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of two roller structures for heat-insulating bracket are provided, and simple, the stressed uniform and stable of this structure fabrication, frictional force are little.
The technological scheme provided according to the utility model, a kind of two roller structures for heat-insulating bracket, comprise the first dunnage and the second dunnage that are arranged on heat insulation loop clip outer surface, it is characterized in that: between described the first dunnage and the second dunnage end, the first roller shaft and the second roller shaft are set, the first roller shaft and the second roller shaft are parallel to each other and locate the same level setting; First roller and second roller identical with being respectively equipped with structure on the second roller shaft at described the first roller shaft.
Described the first roller shaft and the second roller shaft are bolted on respectively on the first dunnage and the second dunnage.
Be provided with the shin plate between described the first dunnage and the second dunnage.
The outside in described the first dunnage and the second dunnage is provided with floor, and described floor is connected with the heat insulation loop clip.
Two roller structures for heat-insulating bracket described in the utility model are made simple, adopt hex head bolt locking, mount and dismount convenient and swift; Two roller structures can guarantee that stress surface has two points to contact with outer steel pipe, stressed uniform and stable; Roller structure frictional force is little, can easily roll across weld seam, is not stuck.
