[0004] In the above patent, the inventor believes that when the patent is in use, the way of limiting the force on the U-shaped tube is directional in a single way, and the U-shaped tube is provided with a single limiting force by the positioning component alone, which cannot ensure the stability of the U-shaped tube's anti-floating property. Utility Model Content

The technical problem to be solved by the utility model is that the current anti-floating device has a single direction of limiting force on the U-shaped tube, and only provides a single limiting force for the U-shaped tube through a positioning component, which cannot ensure the stability of the U-shaped tube anti-floating.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a floating resistance device, which is arranged on a U-shaped tube, comprises a support plate, a pair of first slide seats are slidably connected to the support plate, a fixed plate is fixedly connected to the bottom of each first slide seat, and a pressure plate is fixedly connected to the bottom of the fixed plate, and a folding mechanism is arranged on each first slide seat;

[0010] In a preferred embodiment, the top end of the polished rod is fixedly connected to the lower end surface of the pressure plate.

[0011] In a preferred embodiment, the mobile driving structure includes a pair of second slides slidably connected to the pallet, a worm rotatably connected to the pair of second slides, a first bevel gear fixedly connected to one end of the worm, a bracket fixedly connected to one of the second slides, a second bevel gear rotatably connected to the bracket via a rotating shaft, and a handle fixedly connected to the rotating shaft of the second bevel gear, and the second bevel gear is meshingly connected to the first bevel gear.

[0012] In a preferred embodiment, a second sliding groove for sliding of the second sliding seat is formed on the upper surface of the supporting plate.

[0013] Technical effects and advantages of the utility model:

[0014] 1. The utility model extends the folding mechanism into the U-shaped tube by adjusting the mutual distance between a pair of first slide seats to adapt to the distance between the ports of the U-shaped tube, and by giving the worm wheel a rotating force, the rotation of the bidirectional screw rod can drive a plurality of outer fixing rods to extend outward synchronously to adapt to the tube diameter of the U-shaped tube, thereby giving the U-shaped tube multi-directional floating resistance and limit. At the same time, the pressure plate can act on the port of the U-shaped tube for vertical limitation, thereby ensuring the stability of the floating resistance when the U-shaped tube is backfilled.

[0015] 2. The utility model sets a mobile driving mechanism to adjust the transmission position of the worm in a mobile manner. While satisfying the lateral adjustment of the folding mechanism, a pair of bidirectional screws can be given synchronous driving force at the same time, with high transmission efficiency and fast U-tube limit and anti-floating efficiency.

DETAILED DESCRIPTION

[0022] Combined with reference Figure 1-Figure 4 The utility model provides an anti-floating device, which is arranged on a U-shaped tube. The U-shaped tube in this application is not shown in the figure, and includes a support plate 1. The support plate 1 can be arranged near the landfill of the U-shaped tube. A pair of first slide seats 2 are slidably connected to the support plate 1. A fixing plate 3 is fixedly connected to the bottom of each first slide seat 2, and a pressure plate 4 is fixedly connected to the bottom of the fixing plate 3. The size of the pressure plate 4 is relatively larger than the diameter of the U-shaped tube port on the market. In this way, the pressure plate 4 can conveniently press the U-shaped tube vertically to provide a vertical anti-floating effect. A folding mechanism 5 is arranged on each first slide seat 2. The folding mechanism 5 includes a rotating connection A bidirectional screw rod 51 is connected to the first slide seat 2, a pair of transmission sleeves 52 are transmission-connected to the bidirectional screw rod 51, a light rod 53 movably passes through the pair of transmission sleeves 52, and two pairs of connecting rods 54 are hinged on the sides of each transmission sleeve 52. A pair of connecting rods 54 distributed vertically are hinged with a fixing rod 6. The folding mechanism 5 is used to give a plurality of fixing rods 6 synchronous outward or inward telescopic control, so that the fixing rods 6 can be conveniently controlled to flexibly contact the wall of the U-shaped tube. A worm gear 7 is fixedly connected to the top end of the bidirectional screw rod 51, and a mobile driving structure 8 for driving the pair of worm gears 7 is provided on the support plate 1.

[0023] In this embodiment, by adjusting the lateral position of a pair of first slides 2, the folding mechanism 5 can be extended into the tube to adapt to the spacing of the U-tube ports, and the worm gear 7 is given a rotational force by moving the driving structure 8. In this way, the rotation of the bidirectional screw rod 51 can drive the outer plurality of retaining rods 6 to extend outward synchronously to adapt to the diameter of the U-tube, thereby giving the U-tube a multi-directional anti-floating limit, and cooperating with the pressure plate 4 to vertically press the U-tube to provide a vertical anti-floating effect. In this way, by giving the backfilled U-tube a multi-directional limit, an effective anti-floating effect can be achieved.

[0024] Positioning screws 9 are threadedly penetrated on both sides of the support plate 1. When the U-shaped tube is float-stopped and limited, the positioning screws 9 can be screwed into the ground to stabilize the position of the support plate 1.

[0025] A first slide groove 10 for sliding the first slide 2 is opened through the support plate 1, and a scale line 11 is set on the upper surface of the support plate 1 and near the first slide groove 10. The first slide groove 10 can stabilize the lateral sliding of the first slide 2 and provide a convenient guide for the movement of the folding mechanism 5. The setting of the scale line 11 can facilitate the calibration of the spacing between a pair of first slides 2, so that the folding mechanism 5 can be accurately extended into the tube to adapt to the spacing of the U-shaped tube ends.

[0026] The top end of the light rod 53 is fixedly connected to the lower end surface of the pressure plate 4. The setting of the light rod 53 can provide a linear limiting effect for a pair of transmission sleeves 52 on the bidirectional screw rod 51. In this way, when the bidirectional screw rod 51 rotates, the pair of transmission sleeves 52 can move towards or away from each other, so that the connecting rod 54 can be adaptively folded to drive the fixing rod 6 to move horizontally to limit the wall of the U-shaped tube.

[0027] The mobile driving structure 8 includes a pair of second slides 81 slidably connected to the support plate 1, a worm 82 rotatably connected to the pair of second slides 81, a first bevel gear 83 fixedly connected to one end of the worm 82, a bracket 84 fixedly connected to one of the second slides 81, a second bevel gear 85 rotatably connected to the bracket 84 via a rotating shaft, and a handle 86 fixedly connected to the rotating shaft of the second bevel gear 85. The second bevel gear 85 is meshingly connected to the first bevel gear 83.

[0028] The upper surface of the support plate 1 is provided with a second slide groove 12 for the second slide seat 81 to slide. The second slide groove 12 can stabilize the lateral sliding of the second slide seat 81 , so that the transmission position of the worm 82 can be adjusted easily.

[0029] Specifically, when adjusting the use position of a pair of first slides 2, the worm 82 can be pulled, which can drive the second slide 81 to slide in the second slide groove 12 and move away from the position of the worm gear 7 until the folding mechanism 5 is extended into the U-shaped tube. The worm 82 can be driven by the second slide 81 to fit on the pair of worm gears 7. By turning the handle 86, the second bevel gear 85 can engage with the first bevel gear 83. In this way, the rotation of the worm 82 can drive the bidirectional screw 51 to rotate, so that the tube wall of the U-shaped tube can be limited by the fixing rod 6, so as to facilitate the problem of the U-shaped tube tilting and floating. When the backfill material used for the U-shaped tube is close to solidification, the entire anti-floating device can be taken out, which can be convenient for recycling and reuse.
