Abstract
A kind of rolling support device technical scheme for being applied in sleeve pipe is：Including sleeve pipe, working steel tube, rolling support device, it is characterised in that：Described rolling support device includes base and the ball at the top of which；Described tube chamber welds with base is on working steel tube；The surface of described working steel tube is disposed with anticorrosive coat, heat-insulation layer, outer jacket from inside to outside；Described anticorrosive coat, the contact site between heat-insulation layer, outer jacket and rolling support device are provided with high-strength waterproof material；Described ball and casing-contact；At least 4 sets rolling support devices are uniformly arranged in the same section of described working steel tube.This utility model sets up rolling support device on working steel tube; rolling portion is allowed to contact with internal surface of sleeve pipe; rolling support device is determined according to the Force Calculation of rolling support device along working steel tube length direction spacing; so avoid working steel tube anticorrosive coat, heat-insulation layer and outer jacket it is impaired, so as to reach the effect of protection working steel tube.
Description
Technical field：
This utility model is related to ground heat distribution pipeline technical field, more particularly to a kind of rolling support dress being applied in sleeve pipe
Put.
Background technology：
Buried thermal pipeline needs to use trocar sheath in some special occasions, and due to constraintss such as soil, trocar sheath is
It is irremovable, but the tubular construction that works（Here work tubular construction includes working steel tube, anticorrosive coat, heat-insulation layer and outer jacket）Receive
The change of medium temperature, as the effect expanded with heat and contract with cold frequently can be moved, this results in work tubular construction outer jacket in sleeve pipe
Frequently rub with its inwall, with the passage of pipe network operation time, outer jacket can be constantly damaged so that substantial amounts of extraneous steam oozes
Enter heat-insulation layer, the heat conductivity of heat-insulation layer can drastically raise, ultimately result in pipe insulation and fail comprehensively.
Utility model content：
The technical problem solved by this utility model aims to provide a kind of simple, rolling being applied in sleeve pipe of Applied economy
Dynamic support meanss.
A kind of rolling support device technical scheme for being applied in sleeve pipe of the present utility model is：Including sleeve pipe, work steel
Pipe, rolling support device, it is characterised in that：Described rolling support device includes base and the ball at the top of which；Described bottom
Seat is welded on working steel tube；The surface of described working steel tube is disposed with anticorrosive coat, heat-insulation layer, outer shield from inside to outside
Layer；Described anticorrosive coat, the contact site between heat-insulation layer, outer jacket and rolling support device are provided with high-strength waterproof material
Material；Described ball and casing-contact；At least 4 sets rolling support dresses are uniformly arranged in the same section of described working steel tube
Put.
Described ball adopts stainless steel ball.
The beneficial effects of the utility model：Rolling support device is set up on working steel tube, is allowed in rolling portion and sleeve pipe
Wall is contacted, and rolling support device is determined according to the Force Calculation of rolling support device along working steel tube length direction spacing, so
Avoid working steel tube anticorrosive coat, heat-insulation layer and outer jacket it is impaired, so as to reach the effect of protection working steel tube.
Description of the drawings：
Fig. 1 is structural representation of the present utility model.
1st, sleeve pipe, 2, working steel tube, 3, rolling support device, 4, base, 5, ball, 6, anticorrosive coat, 7, heat-insulation layer, 8, outer
Sheath, 9, high-strength waterproof material.
Specific embodiment：
A kind of rolling support device being applied in sleeve pipe as shown in Figure 1, including sleeve pipe 1, working steel tube 2, rolling
Support arrangement 3, it is characterised in that：Described rolling support device 3 includes base 4 and the ball 5 at the top of which；Described base 4 is welded
It is connected on working steel tube 2；The surface of described working steel tube 2 is disposed with anticorrosive coat 6, heat-insulation layer 7, outer jacket from inside to outside
8；Described anticorrosive coat 6, the contact site between heat-insulation layer 7, outer jacket 8 and rolling support device 3 are provided with high-strength waterproof
Material 9.Described ball 5 is contacted with sleeve pipe 1；At least 4 sets rollings are uniformly arranged in the same section of described working steel tube 2
Support meanss 3.
Rolling support device is set up on working steel tube, allows rolling portion to contact with internal surface of sleeve pipe, rolling support device edge
Working steel tube length direction spacing so avoids the anti-corrosion of working steel tube according to the determination of the Force Calculation of rolling support device
Layer, heat-insulation layer and outer jacket it is impaired, so as to reach the effect of protection working steel tube.
