As a further improvement of the technology, when the three transmission racks are matched with the cement pile, the three first return springs are in a proper pre-compression state.

The friction strip is elastic, so that when the cement pile in the middle of the trigger ring is inclined, the transmission rack in the inclined direction is inwards along the rack sliding groove under the action of the side surface of the cement pile; the transmission rack drives a second gear which is coaxial with the first gear to rotate through a first gear meshed with the transmission rack; the second gear drives the gear ring to rotate in the same direction; the gear ring drives the second transmission shaft to rotate through a third gear meshed with the gear ring; the second transmission shaft drives the first cross universal joint connected with the second transmission shaft to rotate; the first cross universal joint drives the second cross universal joint to rotate through the telescopic column; the second cross universal joint drives an arc-shaped limiting block arranged on the second cross universal joint to swing around the central axis of the transmission rod to three friction strips arranged at the end part of the telescopic rod through the transmission rod connected with the second cross universal joint, and the rotary round block is driven by the transmission rod to rotate in the top block; when the arc-shaped limiting blocks swing around the central axis of the transmission rod for a certain angle, the arc-shaped limiting blocks press the upper end parts of the three friction strips; the side surfaces of the three rubbing strips facing to the inner wall of the limiting sliding cavity are in contact with the inner wall of the limiting sliding cavity in the telescopic sleeve to generate friction so as to prevent the telescopic sleeve from sliding relative to the telescopic rod; if the friction between the side surface of the upper surface facing the inner wall of the limiting sliding cavity and the limiting sliding cavity is not enough to stop the telescopic sleeve from sliding relative to the telescopic rod; the motion of the telescopic sleeve drives the bent parts at the lower ends of the three friction strips to be further curled through the friction between the inner wall of the limiting sliding cavity on the telescopic sleeve and the three friction strips; the bent part of each friction strip is further bent under the driving of the inner wall of the limiting sliding cavity, so that the bent end of each friction strip moves upwards and is wedged between the friction strip and the inner wall of the limiting sliding cavity; the friction between the friction strip and the inner wall of the limiting sliding cavity is improved by wedging the bent end of the friction strip, so that the telescopic sleeve is further prevented from sliding along the telescopic rod.

The friction coefficient of the side surface, matched with the inner wall of the limiting sliding cavity in the telescopic sleeve, of the friction strip is larger than the friction coefficient of the side surface, matched with the outer circular surface of the arc-shaped limiting block, of the friction strip, so that when a cement pile located in the middle of the trigger ring is inclined, a transmission rack located in the inclined direction is inwards along the rack sliding groove under the action of the side surface of the cement pile; the transmission rack drives a second gear which is coaxial with the first gear to rotate through a first gear meshed with the transmission rack; the second gear drives the gear ring to rotate in the same direction; the gear ring drives the second transmission shaft to rotate through a third gear meshed with the gear ring; the second transmission shaft drives the first cross universal joint connected with the second transmission shaft to rotate; the first cross universal joint drives the second cross universal joint to rotate through the telescopic column; the second cross universal joint drives an arc-shaped limiting block arranged on the second cross universal joint to swing around the central axis of the transmission rod to three friction strips arranged at the end part of the telescopic rod through the transmission rod connected with the second cross universal joint, and the rotary round block is driven by the transmission rod to rotate in the top block; the arc-shaped limiting block continuously swings and sequentially presses the three friction strips to be in contact with the inner wall of the limiting sliding cavity and generate friction; because the friction coefficient of the side surface of the friction strip matched with the inner wall of the limiting sliding cavity in the telescopic sleeve is greater than the friction coefficient of the side surface of the friction strip matched with the outer circular surface of the arc-shaped limiting block, the arc-shaped limiting block has very small friction resistance by the three friction strips in the process of swinging towards and acting with the three friction strips, so that the arc-shaped limiting block can swing easily and realize compression on the three friction strips; because the friction coefficient of the side surface of the friction strip matched with the inner wall of the limiting sliding cavity in the telescopic sleeve is greater than the friction coefficient of the side surface of the friction strip matched with the outer circular surface of the arc-shaped limiting block, and the difference between the radius of the inner circular surface of the limiting sliding cavity in the telescopic sleeve and the radius of the outer circular surface of the arc-shaped limiting block is smaller than the thickness of the friction strip, the friction force between the three friction strips and the inner wall of the limiting sliding cavity is very large, so that the telescopic sleeve is prevented from further contracting and sliding along the outer side of the telescopic rod, and further the cement rod is prevented from further inclining; if the friction force between the three friction strips and the inner wall of the limiting sliding cavity is not enough to stop the sliding of the telescopic sleeve, the bent parts at the lower ends of the three friction strips move upwards along with the telescopic sleeve under the driving of the friction force of the inner wall of the limiting sliding cavity and are wedged between the upper end of the friction strips and the limiting sliding cavity, so that the friction force between the friction strips and the limiting sliding cavity is further increased, the telescopic sleeve does not slide relatively along the telescopic rod any more, and the cement pile does not incline any more; meanwhile, the top of the cement pile is hammered continuously, and the cement pile does not move downwards continuously under the action of the stabilizing device; and (5) stopping piling, and continuing piling after the cement pile is corrected to the vertical direction.

The positioning rings are embedded and fixed on the cement piles, and the positioning rings with different inner diameters can be replaced according to the cement piles with different diameters; the positioning rings with different inner diameters are matched with corresponding trigger rings with certain inner diameters, so that the inner diameters of the positioning rings are fixed, positioning rings with different inner diameters are required to be arranged on cement piles with different thicknesses, and the positioning rings with different inner diameters are required to be provided with trigger rings with different inner diameters; the transmission rack in the trigger ring matched with the cement pile can realize a good detection effect on the cement pile, and the first return spring can be pre-compressed properly to better play a role in stabilizing and protecting the cement pile by the trigger ring.

When the three transmission racks are matched with the cement pile, the three first return springs are in a proper pre-compression state, so that the three transmission racks are fully contacted with the outer circular surface of the cement pile; when the cement pile is hammered and inclined, the inclination of the cement pile enables the transmission rack which is fully contacted and matched with the cement pile to timely and effectively press the cement pile to form transmission, so that the telescopic sleeve in the first supporting mechanism, the second supporting mechanism or the third supporting mechanism in the toppling direction of the cement pile is limited within a short time, and the cement pile is prevented from further toppling.

Compared with the traditional cement pile stabilization protection device, the cement pile stabilization device in the invention exists independently of the pile driver and is fixed on the cement pile; in the process of piling by the pile driver, the first support mechanism, the second support mechanism and the third support mechanism in the cement pile stabilizing device can contract along with the downward movement of the cement pile; removing the cement pile stabilizing device after the cement pile is driven into the ground to a certain depth; if the cement pile inclines at a certain angle before reaching a certain depth, the first supporting mechanism, the second supporting mechanism and the third supporting mechanism in the cement pile stabilizing device stop contracting at the same time, and further the cement pile is prevented from further inclining; at the moment, even if the pile driver continues to beat the cement pile, the cement pile can not continue to move downwards; only after the verticality of the cement pile is adjusted, the cement pile can be continuously beaten to reach a certain depth; the invention has simple structure and better use effect.

As shown in fig. 14 and 25, the difference between the radius of the inner circular surface of the limit slide cavity 43 in the telescopic sleeve 42 and the radius of the outer arc surface of the arc-shaped limit block 40 is smaller than the thickness of the friction bar 41.

As shown in fig. 3, the three first return springs 15 are in a suitably pre-compressed state when the three driving racks 14 are engaged with the cement pile.

The design purpose of the friction strips 41 with elasticity is that when the cement pile in the middle of the trigger ring 4 inclines, the three transmission racks 14 respectively slide and contract inwards along the corresponding rack sliding grooves 5 under the action of the side surfaces of the cement pile; the transmission rack 14 drives a second gear 11 which is coaxial with the first gear 13 to rotate through a first gear 13 meshed with the transmission rack; the second gear 11 drives the gear ring 10 to rotate in the same direction; the gear ring 10 drives the second transmission shaft 29 to rotate through the third gear 28 meshed with the gear ring; the second transmission shaft 29 drives the first universal joint cross 31 connected with the second transmission shaft to rotate; the first cross universal joint 31 drives the second cross universal joint 33 to rotate through the telescopic column 32; the second cross universal joint 33 drives the arc-shaped limiting block 40 arranged on the second cross universal joint to swing around the central axis of the transmission rod 34 to three friction strips 41 arranged at the end part of the telescopic rod 23 through the transmission rod 34 connected with the second cross universal joint, and the rotating round block 39 is driven by the transmission rod 34 to rotate in the top block 36; when the arc-shaped limiting block 40 swings at a certain angle around the central axis of the transmission rod 34, the arc-shaped limiting block 40 presses the upper end parts of the three friction strips 41; the side surfaces of the three friction strips 41 facing the inner wall of the limit sliding cavity 43 are in contact with the inner wall of the limit sliding cavity 43 in the telescopic sleeve 42 and generate friction to prevent the telescopic sleeve 42 from sliding relative to the telescopic rod 23; if the friction between the side of the upper wall facing the inner wall of the limit slide chamber 43 and the limit slide chamber 43 is not sufficient to stop the sliding of the telescopic sleeve 42 relative to the telescopic rod 23; the movement of the telescopic sleeve 42 drives the bent parts of the lower ends of the three friction strips 41 to be further curled through the friction between the inner wall of the limiting sliding cavity 43 on the telescopic sleeve and the three friction strips 41; the bent part of each friction strip 41 is further bent under the driving of the inner wall of the limiting sliding cavity 43, so that the bent end of each friction strip 41 moves upwards and is wedged between the friction strip 41 and the inner wall of the limiting sliding cavity 43; the wedging of the curved end of the rub strip 41 increases the friction between the rub strip 41 and the inner wall of the limit slip cavity 43, thereby further preventing the telescoping sleeve 42 from sliding along the telescoping rod 23.

The design purpose that the friction coefficient of the side surface, matched with the inner wall of the limiting sliding cavity 43 in the telescopic sleeve 42, of the friction strip 41 is larger than the friction coefficient of the side surface, matched with the outer circular surface of the arc-shaped limiting block 40, of the friction strip 41 is that when a cement pile positioned in the middle of the trigger ring 4 inclines, the transmission rack 14 positioned in the inclined direction contracts and slides inwards along the rack sliding groove 5 under the action of the side surface of the cement pile; the transmission rack 14 drives a second gear 11 which is coaxial with the first gear 13 to rotate through a first gear 13 meshed with the transmission rack; the second gear 11 drives the gear ring 10 to rotate in the same direction; the gear ring 10 drives the second transmission shaft 29 to rotate through the third gear 28 meshed with the gear ring; the second transmission shaft 29 drives the first universal joint cross 31 connected with the second transmission shaft to rotate; the first cross universal joint 31 drives the second cross universal joint 33 to rotate through the telescopic column 32; the second cross universal joint 33 drives the arc-shaped limiting block 40 arranged on the second cross universal joint to swing around the central axis of the transmission rod 34 to three friction strips 41 arranged at the end part of the telescopic rod 23 through the transmission rod 34 connected with the second cross universal joint, and the rotating round block 39 is driven by the transmission rod 34 to rotate in the top block 36; the arc-shaped limiting block 40 continues to swing and sequentially presses the three friction strips 41 to be in contact with the inner wall of the limiting sliding cavity 43 and generate friction; because the friction coefficient of the side surface of the friction strip 41, which is matched with the inner wall of the limiting sliding cavity 43 in the telescopic sleeve 42, is greater than the friction coefficient of the side surface of the friction strip 41, which is matched with the outer circular surface of the arc-shaped limiting block 40, the arc-shaped limiting block 40 has very small friction resistance by the three friction strips 41 when swinging to and acting with the three friction strips 41, so that the arc-shaped limiting block 40 can swing easily and press the three friction strips 41; because the friction coefficient of the side surface of the friction strip 41 matched with the inner wall of the limiting sliding cavity 43 in the telescopic sleeve 42 is greater than the friction coefficient of the side surface of the friction strip 41 matched with the outer circular surface of the arc-shaped limiting block 40, and the difference between the radius of the inner circular surface of the limiting sliding cavity 43 in the telescopic sleeve 42 and the radius of the outer circular surface of the arc-shaped limiting block 40 is smaller than the thickness of the friction strip 41, the friction force between the three friction strips 41 and the inner wall of the limiting sliding cavity 43 is very large, so that the telescopic sleeve 42 is prevented from further contracting and sliding along the outer side of the telescopic rod 23, and further inclination of the cement rod is prevented; if the friction force between the three friction strips 41 and the inner wall of the limiting sliding cavity 43 is not enough to stop the sliding of the telescopic sleeve 42, the bent parts at the lower ends of the three friction strips 41 move upwards along with the telescopic sleeve 42 under the driving of the friction force of the inner wall of the limiting sliding cavity 43 and are wedged between the upper end of the friction strip 41 and the limiting sliding cavity 43, so that the friction force between the friction strips 41 and the limiting sliding cavity 43 is further increased, the telescopic sleeve 42 does not slide relatively along the telescopic rod 23 any more, and the cement pile does not incline any more; meanwhile, the top of the cement pile is hammered continuously, and the cement pile does not move downwards continuously under the action of the stabilizing device; and (5) stopping piling, and continuing piling after the cement pile is corrected to the vertical direction.

In the invention, the positioning rings 1 are embedded and fixed on the cement piles, and the positioning rings 1 with different inner diameters can be replaced according to the cement piles with different diameters; the positioning rings 1 with different inner diameters are matched with corresponding trigger rings 4 with certain inner diameters, so that the inner diameters of the positioning rings 1 are fixed, positioning rings 1 with different inner diameters are required to be arranged for cement piles with different thicknesses, and the positioning rings 1 with different inner diameters are required to be provided with trigger rings 4 with different inner diameters; the driving rack 14 in the triggering ring 4 matched with the cement pile can realize a good detection effect on the cement pile, and the first return spring 15 can be pre-compressed properly to better exert the stable protection effect of the triggering ring 4 on the cement pile.

When the three driving racks 14 are matched with the cement pile, the design purpose that the three first return springs 15 are in a proper pre-compression state is to enable the three driving racks 14 to be fully contacted with the outer circular surface of the cement pile; when the cement pile is inclined when being hammered, the inclination of the cement pile enables the driving rack 14 which is in full contact fit with the cement pile to timely and effectively press the cement pile to form transmission, so that the telescopic sleeve 42 in the first supporting mechanism 16, the second supporting mechanism 17 or the third supporting mechanism 18 in the dumping direction of the cement pile is limited in a short time and prevents the cement pile from further dumping.

The working process of the invention is as follows: when a cement pile provided with the cement pile stabilizing device is beaten into the ground, if the cement pile is not inclined, the positioning ring 1 of the fixing ring on the cement pile moves downwards along with the cement pile; the positioning ring 1 drives the trigger ring 4 to vertically move downwards; the three driving racks 14 are not triggered, and the first supporting mechanism 16, the second supporting mechanism 17 and the third supporting mechanism 18 contract synchronously along with the downward movement of the cement pile until the cement pile enters a certain depth.

When the cement pile in the middle of the trigger ring 4 is inclined, the transmission rack 14 on the inclined surface of the cement pile is contracted inwards along the rack sliding groove 5 under the action of the side surface of the cement pile, and the corresponding first return spring 15 is compressed; the transmission rack 14 drives a second gear 11 which is coaxial with the first gear 13 to rotate through a first gear 13 meshed with the transmission rack; the second gear 11 drives the gear ring 10 to rotate in the same direction; the gear ring 10 drives the second transmission shaft 29 to rotate through the third gear 28 meshed with the gear ring; the second transmission shaft 29 drives the first universal joint cross 31 connected with the second transmission shaft to rotate; the first cross universal joint 31 drives the second cross universal joint 33 to rotate through the telescopic column 32; the second cross universal joint 33 drives the arc-shaped limiting block 40 arranged on the second cross universal joint to swing around the central axis of the transmission rod 34 to three friction strips 41 arranged at the end part of the telescopic rod 23 through the transmission rod 34 connected with the second cross universal joint, and the rotating round block 39 is driven by the transmission rod 34 to rotate in the top block 36; when the arc-shaped limiting block 40 swings at a certain angle around the central axis of the transmission rod 34, the arc-shaped limiting block 40 presses the upper end parts of the three friction strips 41; the side surfaces of the three friction strips 41 facing the inner wall of the limit sliding cavity 43 are in contact with the inner wall of the limit sliding cavity 43 in the telescopic sleeve 42 and generate friction to prevent the telescopic sleeve 42 from sliding relative to the telescopic rod 23, and the corresponding second return spring 24 is compressed; if the friction between the side of the upper wall facing the inner wall of the limit slide chamber 43 and the limit slide chamber 43 is not sufficient to stop the sliding of the telescopic sleeve 42 relative to the telescopic rod 23; the movement of the telescopic sleeve 42 drives the bent parts of the lower ends of the three friction strips 41 to be further curled through the friction between the inner wall of the limiting sliding cavity 43 on the telescopic sleeve and the three friction strips 41; the bent part of each friction strip 41 is further bent under the driving of the inner wall of the limiting sliding cavity 43, so that the bent end of each friction strip 41 moves upwards and is wedged between the friction strip 41 and the inner wall of the limiting sliding cavity 43; the friction between the friction strip 41 and the inner wall of the limiting sliding cavity 43 is improved by wedging the bent end of the friction strip 41, so that the telescopic sleeve 42 is further prevented from sliding along the telescopic rod 23, and further the cement pile is prevented from continuously inclining; meanwhile, the top of the cement pile is hammered continuously, and the cement pile does not move downwards continuously under the action of the stabilizing device; and (5) stopping piling, and continuing piling after the cement pile is corrected to the vertical direction.

After the cement pile is corrected to the vertical position under the action of external force, the previously pressed transmission rack 14 returns to the initial position under the action of the corresponding first return spring 15, and the transmission rack 14 drives the arc-shaped limiting block 40 to separate from the three friction strips 41 and return to the initial position through the first gear 13, the first transmission shaft 12, the second gear 11, the toothed ring 10, the third gear 28, the second transmission shaft 29, the universal joint assembly 30 and the transmission rod 34; under the action of the corresponding second return spring 24, the telescopic sleeve 42 slides back along the telescopic rod 23 to the initial position; the three elastic friction strips 41 mounted on the end of the telescopic rod 23 are restored.

In conclusion, the invention has the beneficial effects that: the cement pile stabilizing device in the invention exists independently of the pile driver and is fixed on the cement pile; during the driving process of the pile driver, the first support mechanism 16, the second support mechanism 17 and the third support mechanism 18 in the cement pile stabilizing device contract along with the downward movement of the cement pile; removing the cement pile stabilizing device after the cement pile is driven into the ground to a certain depth; if the cement pile inclines at a certain angle before reaching a certain depth, the first supporting mechanism 16, the second supporting mechanism 17 and the third supporting mechanism 18 in the cement pile stabilizing device stop contracting at the same time, and further the cement pile is prevented from further inclining; at the moment, even if the pile driver continues to beat the cement pile, the cement pile can not continue to move downwards; and the cement pile can be continuously beaten to reach a certain depth only after the verticality of the cement pile is adjusted.
