Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, for the utility model discloses an auxiliary stand is used in precast pile construction, rotate in the one side that inserted key 2 was kept away from to spacing piece 1 of every arc and be connected with gyro wheel 3, the axis of rotation of gyro wheel 3 is perpendicular with sleeve 4's axis.
As shown in fig. 1 and 2, each arc-shaped limiting piece 1 is rotatably connected with three pairs of rollers 3, a connecting rod 5 is fixed on each arc-shaped limiting piece 1, and the rollers 3 are rotatably connected with the connecting rods 5. Wherein, the middle part of the arc-shaped limiting sheet 1 is provided with a pair of idler wheels 3, two ends of the arc-shaped limiting sheet 1 are respectively provided with a pair of idler wheels 3, and the idler wheels 3 at the two ends of the arc-shaped limiting sheet 1 incline to the circle center position of the arc-shaped limiting sheet 1.
After the precast pile is inserted into the sleeve 4, the three pairs of idler wheels 3 of the arc-shaped spacing pieces 1 mulberry are in surface contact with the precast pile, so that the sliding friction between the original precast pile and the arc-shaped spacing pieces 1 is converted into the rolling friction between the idler wheels 3 and the precast pile, and the precast pile can be driven into the pile hole easily under the clamping guidance of the arc-shaped spacing pieces 1.
The upper end slope of arc spacing piece 1 is connected with curved guide vane 6, and arc guide vane 6 can lead to inserting the precast pile in sleeve 4 for among the precast pile can be accurate the centre gripping of entering into gyro wheel 3. In addition, after the precast pile enters into sleeve 4 and contacts with arc guide vane 6, the precast pile can be automatic push in the jack with inserted key 2, and need not artifical pulling inserted key 2 and make the precast pile can be automatic get into among the centre gripping of gyro wheel 3.
Further, the components for clamping and positioning the precast pile, such as the fasteners 7, are provided in a set at each of the upper and lower ends of the sleeve 4. The upper and lower two groups of fasteners 7 can guide and position the precast pile more accurately and stably.
The arc-shaped limiting piece 1 is connected with an insertion rod 8, the cross section of the insertion rod 8 in the length direction is square, one end, far away from the arc-shaped limiting piece 1, of the insertion rod 8 is connected with a magnet block 9, an insertion groove 10 for inserting the insertion rod 8 is formed in the insertion key 2, and the cross section of the insertion groove 10 in the length direction is also square. When the insertion rod 8 is inserted into the insertion groove 10 on the iron insertion key 2, the insertion rod 8 is inserted and connected together through the adsorption of the magnet block 9, so that the insertion key 2 is detachably connected with the arc-shaped spacing piece 1 and the roller 3 thereon. The insertion rod 8 cannot rotate in the insertion groove 10 in the circumferential direction, so that the arc-shaped limiting sheet 1 and the roller 3 can be accurately connected with the insertion key 2, and the precast pile can be guided and positioned.
After long-term use, a large friction force may exist between the insertion key 2 and the insertion hole, at this time, the insertion key 2 cannot be retracted into the insertion hole when the arc-shaped guide piece 6 contacts with the precast pile, and the roller 3 and the arc-shaped limiting piece 1 are deformed or damaged by the pressure of the precast pile. At this time, the insertion rod 8 can be conveniently pulled out from the insertion groove 10 to replace the roller 3 and the arc-shaped limiting sheet 1.
Since the arc-shaped spacing piece 1 is connected to the inserting key 2 by the magnetic connection of the inserting rod 8 and the inserting key 2, when the elastic piece 13 is abutted against the arc-shaped spacing piece 1, the elastic piece 13 can push the inserting rod 8 out of the inserting groove 10. Therefore, a limiting ring 12 fixed coaxially with the inserting key 2 is arranged at one end of the inserting key 2 provided with the inserting groove 10, the elastic piece 13 is sleeved on the inserting key 2, one end of the elastic piece abuts against the limiting ring 12, the other end of the elastic piece abuts against the inner wall of the groove 11, and the preformed pile is clamped by driving the inserting key 2 through the elastic piece 13.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
