Abstract
The utility model relates to a stress compensation movable support for an oil-gas pipeline, belonging to the field of construction technology of pipeline engineering. The stress compensation movable support consists of an upper pipe clamp, a lower pipe clamp, a support frame and a hydraulic damping device, wherein the upper pipe clamp and the lower pipe clamp are half rounds with the same diameter and are fixedly connected by a bolt; the support frame is welded at the bottom of the lower pipe clamp; and the bottom of the support frame is provided with a screw hole and connected with the hydraulic damping device through a bolt. The stress compensation movable support provided by the utility model is used for supporting and mounting a pipeline at a tunnel opening; the upper and lower pipe clamps fix the pipeline; the hydraulic damping device is fixed on a tunnel bottom plate; the pipe clamps move upwards or downwards along with the pipeline within the design load range; and the hydraulic damping device realizes the stress release of the pipeline so as to ensure the safety of the support.
Description
Technical field
The utility model relates to oil and gas pipes stress compensation movable bearing support, belongs to the pipework technical field of construction, especially tunnel crossing pipeline design and installation technical field.
Background technique
In the oil and gas pipes construction, adopt a series of slips to hang down bearing, piping erection in the pipe clamp on bearing top, because of pipeline is moved vertically, is needed the Installation Stress compensation device, caused that with reduction temperature, pressure surge pipeline axial stress is concentrated.The patent No. is 200720086239.0 to disclose a kind of novel pipeline bearing; Form by dunnage, the pole that is connected with dunnage, be connected with two bracing struts on the dunnage, on the axle between two bracing struts, cylinder is housed; Dish spring spare is connected on the pole between the base plate of pressing plate and can; Its adjustable height can adapt to displacement, the vibration of ability extraction duct, the load change of adaptation pipeline when thermal walking that pipeline produces, but not have pipe clamp; The pipeline degrees of freedom is too high, possibly break away from bearing; The patent No. is 92200440.4 to disclose a kind of piston autobalance type compensator, is made up of one or more annular pistons, and it is long-pending that its piston gross area approximates the core tube section; Be installed on core tube wall; Between piston/cylinder and the core pipe connecting tube or hole are arranged, its great advantage is to eliminate the end thrust of pipeline, and the major defect of existence is to eliminate the radial thrust that pipe deforming produces; Possibly cause pipe clamp or bearing to destroy, influence the pipe safety operation.
Summary of the invention
The purpose of the utility model is for overcoming existing oil and gas pipes bearing pipe clamp or the bearing malicious event defective that particularly tunnel bearing installation afterwards causes because of the pipe bending distortion to be installed, and a kind of movable bearing support with stress compensation function is provided.
The utility model is made up of last pipe clamp, following pipe clamp, supporting frame, hydraulic damping device; Last pipe clamp, following pipe clamp are the identical semicircle of diameter, are connected by bolt and fix, and following pipe clamp bottom is welded with supporting frame; The bottom of supporting frame has screw, is connected with the hydraulic damping device through bolt.
The hydraulic damping device is by movable inverted draw cut, fixedly kerve, cylinder body, bidirectional piston bar, piston are formed, and fixedly the cross section of kerve is " U " connected in star, and movable inverted draw cut is connected in " U " connected in star of fixing kerve, and is connected with supporting frame through bolt; The upper/lower terminal of cylinder body has through hole, and its support is fixed on fixedly on the kerve; Bidirectional piston is made up of upper piston rod, the lower piston rod of same diameter, and is connected fixing with the upper and lower end face of piston; Upper piston rod passes cylinder body upper end through hole, and is connected with movable inverted draw cut and fixes, and lower piston rod passes cylinder body lower end through hole; Piston is equipped with up one-way throttle valve and descending one-way throttle valve.
The utility model is used for tunnel portal place pipeline and supports installation; Upper and lower pipe clamp fixing tube, the hydraulic damping device is fixed on the tunnel floor, and pipe clamp takes place upwards with pipeline or when falling displacement after rise in the design load scope; Realize that by the hydraulic damping device pipe stress discharges, and guarantees bearing safety.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
Can be known by Fig. 1: the utility model is by last pipe clamp 1, pipe clamp 2, supporting frame 3, hydraulic damping device 4 are formed down; Last pipe clamp 1, pipe clamp 2 be the identical semicircle of diameter down, is connected by bolt and fixes, and following pipe clamp 2 bottoms are welded with supporting frame 3; The bottom of supporting frame 3 has screw, is connected with hydraulic damping device 4 through bolt.
Hydraulic damping device 4 is by movable inverted draw cut 5, fixedly kerve 6, cylinder body 7, bidirectional piston bar 8, piston 9 are formed; Fixedly the cross section of kerve 6 is " U " connected in star, and movable inverted draw cut 4 is connected in " U " connected in star of fixing kerve 5, and is connected with supporting frame 3 through bolt; The upper/lower terminal of cylinder body 7 has through hole, and its support is fixed on fixedly on the kerve 6; Bidirectional piston 8 is made up of upper piston rod 8a, the lower piston rod 8b of same diameter, and is connected fixing with the upper and lower end face of piston 9; Upper piston rod 8a passes cylinder body 7 upper end through holes, and is connected fixingly with movable inverted draw cut 5, and lower piston rod 8b passes cylinder body 7 lower end through holes; Piston 9 is equipped with up one-way throttle valve 10 and descending one-way throttle valve 11; Be full of hydraulic oil 12 in the cylinder body 7.
The oil and gas pipes distortion produces radial thrust; When power that draws high that piston rod 8 receives or downforce reached scope of design, up one-way throttle valve 10 or descending one-way throttle valve 11 were opened, and hydraulic oil 12 flows between the upper and lower chamber of cylinder body through one-way throttle valve; Piston 9 rises or descends; Thereby realize that pipe stress discharges, avoid pipe clamp or bearing to destroy, guarantee the oil-gas pipeline safety operation.
