Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, the pile sleeve 1 with the inner diameter adjusting device of the present invention is an annular cylinder, the pile sleeve 1 is sleeved on the upper end of a pile 2 to be driven when performing pile driving operation, the inner diameter adjusting device comprises a lining plate 3, a support plate 4, a first adjusting stud 5-1, a second adjusting stud 5-2, and an adjusting nut 6, the lining plate 3 and the support plate 4 are mutually attached and fixed by screws, the first adjusting stud 5-1 is screwed into the support plate 4 through a screw hole provided on the cylinder wall of the pile sleeve 1, the second adjusting stud 5-2 is attached to the support plate 4 through a screw hole provided on the cylinder wall of the pile sleeve 1, the adjusting nut 6 is sleeved on the portions of the first adjusting stud 5-1 and the second adjusting stud 5-2 exposed outside the cylinder wall of the pile sleeve 1, and the end face of the adjusting nut 6 is attached to the outer end face of the cylinder wall of the pile sleeve 1, so as to fix and limit the first adjusting stud 5-1 and the second adjusting stud 5-2.
At least three height positions of the cylinder wall along the height direction of the pile sleeve 1 are respectively provided with a plurality of screw holes which are uniformly distributed along the circumferential direction of the pile sleeve 1, wherein the first adjusting stud 5-1 and the second adjusting stud 5-2 penetrate through the screw holes which are arranged at different height positions along the height direction of the pile sleeve 1 at intervals.
As a specific embodiment, for example, three height positions in the height direction from the upper end to the lower end of the pile sleeve 1 are a first height position, a second height position, and a third height position, respectively, and at the first height position, a first circle of screw holes is provided which is uniformly distributed on the pile sleeve 1 in the circumferential direction of the pile sleeve 1, at the second height position, a second circle of screw holes is provided which is uniformly distributed on the pile sleeve 1 in the circumferential direction of the pile sleeve 1, and at the third height position, a third circle of screw holes is provided which is uniformly distributed on the pile sleeve 1 in the circumferential direction of the pile sleeve 1. One group of first adjusting studs 5-1 penetrates through a first circle of screw holes uniformly distributed on a first height position along the circumferential direction of the pile sleeve 1, the second adjusting studs 5-2 penetrates through a second circle of screw holes uniformly distributed on a second height position along the circumferential direction of the pile sleeve 1, and the other group of first adjusting studs 5-1 penetrates through a third circle of screw holes uniformly distributed on a third height position along the circumferential direction of the pile sleeve 1. It goes without saying that the sum of the number of the first and third circles of screw holes equals the number of the first adjusting studs 5-1, the number of the second circle of screw holes equals the number of the second adjusting studs 5-2, and the number of the adjusting nuts 6 equals the sum of the number of the first and second adjusting studs 5-1 and 5-2. Furthermore, every second first adjusting stud 5-1 and every second adjusting stud 5-2 corresponds to a backing plate 3 and a support plate 4.
A first adjusting stud 5-1 which penetrates through a screw hole arranged on the wall of the pile sleeve 1 and is screwed into the support plate 4 plays a role in pulling the support plate 4; the second adjusting stud 5-2 which passes through the screw hole arranged on the wall of the pile sleeve 1 and is attached to and propped against the support plate 4 plays a role in pushing the support plate 4. By the pulling action of the first adjusting stud 5-1, the support plate 4 can be moved away from the radial center along the radial direction of the pile sleeve 1, i.e. the inner diameter of the pile sleeve 1 is increased; by the "pushing" action of the second adjusting stud 5-2, a movement of the support plate 4 in the radial direction of the pile sleeve 1 close to the radial center, i.e. a reduction of the inner diameter of the pile sleeve 1, may be achieved.
The lining plate 3 and the supporting plate 4 can be rectangular thick plates and have certain strength and rigidity. Preferably, the lining plate 3 is a steel plate with good wear resistance, which can effectively prolong the service life of the contact part when the pile sleeve 1 is frequently sleeved into the pile 2 to be driven.
It goes without saying that the screw hole provided on the wall of the pile sleeve 1, the first adjusting stud 5-1, the second adjusting stud 5-2 and the adjusting nut 6 are of a specification matching one another.
The use method of the pile sleeve with the inner diameter adjusting device comprises the following steps: when the outer diameter of the pile to be driven 2 is increased, the adjusting nut 6 is loosened, then the first adjusting stud 5-1 is screwed towards the outer side of the pile sleeve 1, so that the supporting plate 4 and the lining plate 3 are pulled to move away from the radial center along the radial direction of the pile sleeve 1, the inner diameter of the pile sleeve 1 is increased until the lining plate 3 is attached to the pile to be driven 2, and finally the adjusting nut 6 is screwed; when the outer diameter of the pile 2 to be driven is reduced, the adjusting nut 6 is loosened, then the second adjusting stud 5-2 is screwed towards the inside of the pile sleeve 1, thereby pushing the support plate 4 and the backing plate 3 to move closer to the radial center in the radial direction of the pile sleeve 1, so that the inner diameter of the pile sleeve 1 is reduced until the backing plate 3 abuts the pile 2 to be driven, and finally the adjusting nut 6 is screwed.
The pile sleeve with the inner diameter adjusting device can quickly change the inner diameter of the pile sleeve to adapt to driven piles of different specifications, improves the operation efficiency and flexibility of adjusting the inner diameter of the pile sleeve during site construction, and prolongs the service life of the pile sleeve due to the arrangement of the lining plate.
