Example (b):
referring to fig. 1, for the utility model discloses a static pressure stake machine pile follower of adjustable length, including from the top down the last pile follower portion 1, extension bar 3 and the lower pile follower portion 2 that connect gradually. Wherein, the top end of the upper pile-feeding part 1 is bolted with a hanging ring 11, the number of the extension bars 3 is more than or equal to one, and the bottom end of the lower pile-feeding part 2 is integrally formed with an arc-shaped convex block 21. Rings 11 facilitate the crane to extract the pile feeder after the pile feeding operation is completed, and arc-shaped projections 21 enable the lower pile feeding part 2 to be better matched with the lower tubular pile.
Referring to fig. 1, tenon 4 is integrally formed at one end of upper pile feeding part 1 and extension rod 3 facing lower pile feeding part 2, and mortise 5 is formed at one end of extension rod 3 and lower pile feeding part 2 facing upper pile feeding part 1. When the number of extension bar 3 is no less than two sections, tenon 4 at the bottom end of upper pile feeding part 1 is in inserting fit with mortise 5 at the top end of first extension bar 3, tenon 4 at the bottom end of last extension bar 3 is in inserting fit with mortise 5 at the top end of lower pile feeding part 2, and tenon 4 at the bottom end of other extension bars 3 is in inserting fit with mortise 5 at the top end of lower extension bar 3. In addition, a bolt 6 passes through the side wall of the mortise 5 and the tenon 4 along the radial line direction of the extension bar 3, so that the mortise 5 is stably connected with the tenon 4.
The structure of mortise 5 and tenon 4 is identical everywhere, can change the pitch of extension bar 3 wantonly during the construction according to actual conditions, makes the whole length of last pile feeding portion 1, extension bar 3 and lower pile feeding portion 2 and send a degree of depth phase-match.
Taking the joint of the pile feeding part 1 and the first section extension bar 3 as an example, referring to fig. 1 and 2, the axis of the mortise 5 passes through the axis of the extension bar 3, the two ends of the mortise 5 are communicated with the side wall of the extension bar 3, and the cross section of the mortise 5 is dovetail-shaped. The shape of the tenon 4 is matched with the mortise 5, and the tenon is matched with the mortise 5 in a sliding insertion manner along the axial direction of the mortise 5.
Referring to fig. 2, the cross pin 6 is disposed along the radial line of the extension bar 3, and the axis of the cross pin 6 is perpendicular to the axis of the mortise 5. A limiting block 61 and an elastic cushion block 63 are arranged at one end of the bolt 6, and a clamping groove 62 is formed in the side wall of the other end of the bolt. The cylindrical limiting block 61 is welded and fixed with the end face of the bolt 6, the elastic cushion block 63 made of rubber is in a circular ring shape and is sleeved on the bolt 6 in a sliding mode, and the notch of the clamping groove 62 faces upwards.
Referring to fig. 2, a counterbore 33 is formed in the side wall of the extension bar 3, and the axis of the counterbore 33 coincides with the axis of the plug pin 6. Constructor has the one end that the draw-in groove 62 was opened to bolt 6 and has penetrated extension bar 3, along with deepening gradually of bolt 6, stopper 61 and elastic cushion 63 sink gradually in counter bore 33 until elastic cushion 63 offsets with the counter bore 33 bottom, and the one end of 6 opening draw-in grooves 62 of bolt is just leveled with the lateral wall of extension bar 3 this moment.
Referring to fig. 2, the slide groove 31 is formed in the side wall of the extension bar 3, which faces away from the limiting block 61, the axis of the slide groove 31 is vertical, the top end of the slide groove 31 is communicated with the top end face of the extension bar 3, and the cross section of the slide groove 31 is in a T shape. A clamping block 32 is arranged in the sliding groove 31 in a sliding mode, the main structure of the clamping block 32 is matched with the sliding groove 31, and the bottom end of the clamping block 32 protrudes downwards and is clamped with the clamping groove 62 in a sliding mode.
When the elastic cushion block 63 abuts against the bottom of the counter bore 33, the constructor needs to continuously press the limiting block 61 to deform the elastic cushion block 63, and the plug pin 6 continues to go deep, so that the clamping groove 62 can be aligned with the clamping block 32. The bottom end of the clamping block 32 slides into the clamping groove 62, then the limiting block 61 is loosened, the elastic cushion block 63 rebounds to drive the bolt 6 to move, so that the side wall of the clamping groove 62 is abutted against the side wall of the bottom end of the clamping block 32, and the clamping block 32 is stabilized at the position by static friction force.
Referring to fig. 2, two finger grooves 34 are formed on one side of the latch 32 facing away from the stopper 61. When the bolt 6 is pulled out, a constructor needs to press the limiting block 61 first to press the finger groove 34, slide the clamping block 32 out of the clamping groove 62, and then pull out the bolt 6 reversely.
The side wall of the lower pile-feeding part 2 is also provided with the counter bore 33, the sliding groove 31 and the clamping block 32, and the principle and the working process of the lower pile-feeding part are consistent with those of the extension rod 3.
Referring to fig. 1, arc-shaped grooves 35 are formed in the side wall of the extension bar 3 in pairs, and handles 36 are welded to the tops of the inner walls of the grooves 35, so that the extension bar can be conveniently held by constructors. The constructor holds the handle 36 and applies force to the extension bar 3 to right or align the extension bar 3.
The implementation principle of the embodiment is as follows:
the tenon 4 at the bottom end of the upper pile feeding part 1 is inserted into the mortise 5 at the top end of the first section extension bar 3, and then the bolt 6 is inserted, so that the upper pile feeding part 1 can be connected with the first section extension bar 3. The tenon 4 at the bottom end of the last lengthening rod 3 is inserted into the mortise 5 at the top end of the lower pile feeding part 2, and then the bolt 6 is inserted, so that the last lengthening rod 3 and the lower pile feeding part 2 can be connected. Under the condition that the number of the extension bars 3 is more than or equal to two, the adjacent two extension bars 3 can be connected in the same way. Because the structure of tenon 4 and mortise 5 has the commonality, so constructor can set up extension bar 3 of arbitrary festival number between last pile follower portion 1 and lower pile follower portion 2 according to actual conditions to can be used to the super deep pile follower operation of various depths, application scope is wide.
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.
