Description
Technical field
The utility model relates to a kind of experimental facilities, is specifically related to a kind of PE corrugated tube closed-water test automatic compacting device.
Background technology
Double wall corrugated high-density polyethylene pipes is called for short PE corrugated tube.PE corrugated tube is a kind of novel tube with ring texture outer wall and smooth internal walls, and first the beginning of the eighties succeeds in developing in Germany.PE corrugated tube take high density polyethylene as a kind of novel light tubing of raw material, and have the features such as lightweight, high pressure resistant, good toughness, construction fast life-span be long, the structural pipe wall design of its excellence, compared with the tubing of other structures, cost reduces greatly.And due to easy to connect, reliable, be at home and abroad used widely.A large amount of alternative concrete pipe and cast carbon steel.PE corrugated tube has the performance of excellent chemical stability, ageing-resistant and resisting environmental stress and cracking.The PE corrugated tube produced for starting material by it belongs to flexible pipe.Outer wall is wave structure ringwise, greatly strengthen the ring stiffness of tubing, thus enhances the resistibility of pipeline to soil load, and at this aspect of performance, PE corrugated tube has obvious advantage compared with other tubing.
PE corrugated tube needs through closed-water test, and general to close water experiment be need the flared part manually pinning PE corrugated tube to be pressed into closed-water test by fork truck.Because fork truck is larger toward strength when pressing down, and manually cannot pin flared part completely, swing constantly during press-in, the socket of press-in and waterproof apron is caused to tilt, waterproof apron can not play sealing function after tilting well, so the success ratio of this test is not high, affect the validity of experimental result.
Utility model content
Technical problem to be solved in the utility model is, during PE corrugated tube closed-water test, very easily causes inclination, can not play sealing function during press-in waterproof apron.
For achieving the above object, the technical solution of the utility model is: PE corrugated tube closed-water test automatic compacting device, comprise base, described base is provided with vertical pole, described pole top is fixedly connected with the cross bar of level, and also rotate between described cross bar and base and be provided with vertical screw rod, described screw rod is positioned at the inner side of pole, on described screw rod, threaded engagement is connected with pressing plate, and the below of described pressing plate is provided with floating claw, the inner side described base being positioned at screw rod is also provided with stationary jaw, the outside described base being positioned at pole is also provided with a motor, on the output shaft of described motor, key is connected with an output wheel, the below of described base is provided with a driving pulley and a driven pulley, described driving pulley is positioned at the below of one of them screw rod, described driven pulley is positioned at the below of another screw rod, the rotating shaft separately of described driving pulley and driven pulley passes through bevel gear drive with the screw rod of correspondence respectively, described output wheel, driving pulley is connected by driving-belt with driven pulley, described driving pulley is identical with the diameter of driven pulley.
When adopting technique scheme, two screw rods are rotatably connected on cross bar and base respectively, and a screw rod is connected with driving pulley by bevel gear, and another screw rod is also connected with driven pulley by bevel gear.When electric machine rotation, driving pulley and driven pulley is driven to rotate by driving-belt, thus drive screw turns.Because driving pulley is identical with the diameter of driven pulley, driving pulley is identical with the rotating speed of driven pulley, as long as and then adopt the gear drive of same specification, just can ensure that the rotating speed of two screw rods is identical, can ensure that the pressing plate on screw rod is move under horizontality substantially.Because adopting screw drive mode, downward larger pressure can be provided to pressing plate in the process of bolt rotary.To utilize on pressing plate two stationary jaws can fix the flared part of PE corrugated tube, replace traditional artificial fixing, serve spacing and effect that is anti-dumping, and reliability is higher.Moreover, fix waterproof apron by floating claw, during by external force drive screw turns, act on pressing plate, the waterproof apron be fixed on pressing plate slowly can be pressed in PE corrugated tube by floating claw.Rotate owing to being provided with two screw rods simultaneously, such pressing plate can the state of maintenance level substantially in the process moved downward, and the speed and strength of press-in can adjust according to actual needs, can like clockwork waterproof apron be pressed in PE corrugated tube, prevent waterproof apron run-off the straight in the process of press-in, cause the success ratio of experiment not high.
Further, described base is also provided with a stretching pulley, described base offers the chute of level, the mount pad of described stretching pulley slides and is arranged in chute, and described mount pad is provided with clamping screw.Arrange stretching pulley, when needs tensioning, unclamp clamping screw, tensioning of sliding in chute takes turns to suitable position, then tightens clamping screw, thus fixes stretching pulley, plays the effect of tensioning.
Further, the diameter of described driving pulley and driven pulley is greater than the diameter of output wheel.This setting effectively can reduce the rotating speed of screw rod, avoids that the rotating speed of screw rod is excessive causes the too fast compression waterproof apron of pressing plate.
Further, described driving-belt is tooth bar band.
