Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses a casing pile. Referring to fig. 1, the casing pile comprises a pile body 1, the pile body 1 is a cylinder which penetrates through in the axial direction, a convex edge 3 is integrally formed on the side wall of one end portion of the pile body 1 in the circumferential direction, the radial cross section of the convex edge 3 is in the shape of a circular ring, the convex edge 3 is coaxial with the pile body 1, and the inner ring of the convex edge 3 is tightly attached to the outer side wall of the pile body 1. The one end that is provided with protruding edge 3 on pile body 1 can be dismantled and is connected with connecting piece 2, and the radial cross sectional shape of connecting piece 2 is circular and connecting piece 2 and pile body 1 coaxial setting, and the external diameter size of connecting piece 2 is the same with the external diameter size of pile body 1. A plurality of handles 4 are welded at one end of the connecting piece 2 far away from the pile body 1, two handles 4 are used for illustration in the embodiment, the two handles 4 are vertically intersected, and the middle parts of the two handles 4 are overlapped. In-process that snatchs the casing pile at the loop wheel machine, couple on the loop wheel machine acts on protruding edge 3 and handle 4 respectively, makes the loop wheel machine have dual guarantee to the stability that the casing pile snatched, when the couple pine of one of them part takes off, the couple of another part still can be hoisted the casing pile, has improved the stability of casing pile when snatching.

In order to enable the pile body 1 to be smoothly inserted into a drilled hole in the lowering process, an arc-shaped chamfer 14 is arranged on the outer edge of the end part of one end, far away from the connecting piece 2, of the pile body 1, the arc-shaped chamfer 14 has a guiding effect on the pile body 1, and in the inserting process of the pile body 1, the arc-shaped chamfer 14 abuts against the side wall of the hole to enable the pile body 1 to slide into the drilled hole, so that the hole aligning time of the pile body 1 is shortened, and the working efficiency of operation is improved.

Referring to fig. 2 and 3, in order to fix the pile body 1 and the connecting piece 2, the lower surface of the connecting piece 2 is symmetrically welded with the axis of the connecting piece 2 to form two fixing rods 5, each fixing rod 5 comprises a vertical rod 51 and a horizontal rod 52, the vertical rod 51 is perpendicular to the lower surface of the connecting piece 2, the horizontal rod 52 is perpendicularly arranged at one end of the vertical rod 51 far away from the connecting piece 2, and the vertical rod 51 and the horizontal rod 52 are integrally T-shaped. The upper end face of the pile body 1 is provided with a fixing groove 6 for the insertion of the fixing rod 5, the depth of the fixing groove 6 is the sum of the length of the vertical rod 51 and the height of the cross rod 52, the opening length of the fixing groove 6 is equal to the length of the cross rod 52, and the opening width of the fixing groove 6 is larger than the width of the cross rod 52. Offer at the lateral wall of fixed slot 6 and supply montant 51 to use the axis of connecting piece 2 to carry out the first groove 7 that slides that rotates and slide as the axis, offer at the lateral wall of fixed slot 6 and supply horizontal pole 52 to use the axis of connecting piece 2 to carry out the second groove 8 that slides that rotates and slide as the axis, first groove 7 that slides and second groove 8 that slides are same one side of fixed slot 6. After dead lever 5 on connecting piece 2 is pegged graft in fixed slot 6, rotate connecting piece 2 and make horizontal pole 52 at the 8 rotations in second groove 8 that slide, use the loop wheel machine to snatch connecting piece 2 this moment, horizontal pole 52 and the last lateral wall joint in second groove 8 that slides makes horizontal pole 52 can't fall out from pile body 1 to the fixing between pile body 1 and connecting piece 2 has been realized.

In order to reduce the condition that the in-process that connecting piece 2 was snatched takes place to slide in second groove 8 that slides, the welding of one side of keeping away from second groove 8 has spring 9 on horizontal pole 52 towards, and spring 9 is whole can carry out arc deformation and the deformation radian of spring 9 is the same with the radian of sliding of horizontal pole 52. When the cross rod 52 is installed in the fixing groove 6, the spring 9 abuts against the side wall of the fixing groove 6, the connecting piece 2 is rotated to enable the cross rod 52 to move to the other side of the second sliding groove 8, the spring 9 is still in a compressed state at the moment, the spring 9 applies elastic abutting force to the cross rod 52, the possibility that the cross rod 52 slides in the second sliding groove 8 is reduced, and the stability of the cross rod 52 in the using process is improved.

In order to reduce the radial condition of sliding of spring 9 in the in-process of extension, the welding of one side of keeping away from fixed slot 6 on second groove 8 that slides has guide bar 10, and guide bar 10 is an arc pole, and the radian of guide bar 10 is the same with the radian of second groove 8 that slides, offers the breach 11 that supplies guide bar 10 to slide on horizontal pole 52, and breach 11 runs through the lower surface of horizontal pole 52. In the sliding process of the cross rod 52, the spring 9 gradually extends to enable the spring 9 to be sleeved on the outer surface of the guide rod 10, and the guide rod 10 radially limits the spring 9 at the moment so as to reduce the radial sliding condition of the spring 9 and enable the spring 9 to have a good abutting effect on the cross rod 52 all the time.

Referring to fig. 4, in order to reduce the fracture of the cross bar 52 during the lifting process, the cushion 12 is thermally fused on the upper end surface of the cross bar 52, in this embodiment, the cushion 12 is made of rubber, when the cross bar 52 abuts against the upper side wall of the second sliding groove 8, the cushion 12 cushions the stress between the two, so that the compressive stress on the cross bar 52 is reduced, and the fracture of the cross bar 52 during the use process is reduced.

In order to reduce the condition that the loop wheel machine broke off connecting piece 2 when catching on handle 4 and take place, the one end welding of keeping away from handle 4 on connecting piece 2 has a plurality of strengthening ribs 13, and strengthening rib 13 vertically and horizontally staggered sets up, and the structural strength of connecting piece 2 has been strengthened in the setting of strengthening rib 13, and when the loop wheel machine hoisted handle 4, the setting of strengthening rib 13 made connecting piece 2 be difficult for taking place the fracture, has improved the security of connecting piece 2 in the use.

The implementation principle of the casing pile in the embodiment of the application is as follows: in the lowering process of the casing pile, a crane is used for grabbing the convex edge 3 and the handle 4, at the moment, the arc-shaped chamfer 14 is used for quickly inserting the bottom of the casing pile into the hole, and the pipe jacking machine is used for pressing the casing pile into the hole; when the casing pile inserts the stratum completely, rotate connecting piece 2 and make dead lever 5 slide to fixed slot 6 play, upward movement takes off connecting piece 2 from 1 top of pile body, can carry out the pouring of transferring of steel reinforcement cage and concrete to pile body 1 this moment.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
