Description

Technical Field

[0001] The utility model relates to the technical field of pile drivers, in particular to an anti-deviating pile driver. Background Art

[0002] A pile driver consists of a pile hammer, a pile frame and auxiliary equipment. The pile hammer is attached between two parallel vertical guide rods (commonly known as gantry) at the front of the pile frame and is lifted by a lifting hook. The pile frame is a steel structure tower with a winch at the rear to lift the pile and the pile hammer. There is a guide frame composed of two guide rods in front of the pile frame to control the direction of piling so that the pile can penetrate the formation accurately according to the designed direction. The basic technical parameters of a pile driver are the weight of the impact part, the impact kinetic energy and the impact frequency. Pile hammers can be divided into drop hammers, steam hammers, diesel hammers and hydraulic hammers according to the power source of the movement.

[0003] According to a Chinese patent document with the announcement number CN218667517U, an anti-deviating pile driver is disclosed, which includes a support seat, a slide plate, a telescopic hydraulic cylinder, a pile driver body and a positioning plate, wherein the bottom of the support seat is slidably connected with the slide plate, the bottom end surface of the slide plate is fixedly mounted with a telescopic hydraulic cylinder, and the top of the support seat is fixedly mounted with the pile driver body. The corresponding pipe pile is placed in the opening of the positioning plate, and then the electric push rod is turned on, so that the output end of the electric push rod pushes the clamping plate to clamp the pipe pile, thereby avoiding the phenomenon of pipe pile deviation during piling and enhancing practicality.

[0004] The above-mentioned equipment clamps the pipe piles by means of the clamping plates on the positioning plates, so that the pipe piles will not deviate during operation. However, when the equipment is in use, the reaction force generated by overcoming the deviation of the pipe piles due to hammering will directly act on the clamping plates and related fixing parts. The reaction force generated by overcoming the deviation of the pipe piles due to hammering will generally be very large, which will result in a very short service life of the related parts of the anti-deviation mechanism.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, an anti-deviating pile driver includes a base 1, which is a rectangular plate-shaped structure, and a screw support foot 4 is fixedly installed at the bottom of the base 1, and four of the support feet 4 are distributed at the four corners of the base 1. A support column 2 is fixedly installed on the upper end of the base 1, and two support rods 3 are fixedly connected above the rear end side wall of the support column 2, and the two support rods 3 are inclined relative to the horizontal plane. The other ends of the two support rods 3 are fixedly connected to the upper end of the base 1 and are symmetrically distributed on both sides of the support column 2, and two fixing plates 5 are fixedly installed on the top of the support column 2, and the two fixing plates 5 are symmetrically distributed on the top of the support column 2. A plurality of guide wheels 18 are rotatably installed between the two fixing plates 5, and the plurality of guide wheels 18 are linearly distributed between the two fixing plates 5. A first fixing frame 6 is also fixedly installed on the upper end of the base 1, and the first fixing frame 6 is fixed to the base 1 by a plurality of fixing bolts 8. Fixed connection, a winch 7 is fixedly installed on the first fixed frame 6, and a steel cable 11 is wound on the winding drum of the winch 7. The other end of the steel cable 11 passes through a plurality of guide wheels 18 in sequence and is fixedly connected with a hammer 12. The hammer 12 is vertically placed at the front end of the supporting column 2. An empty slot 19 is provided on the base 1 below the hammer 12. An anti-deviation mechanism acting on the hammer 12 is installed on the supporting column 2. The anti-deviation mechanism includes a slider 14 and a connecting rope 16. The slider 14 is slidably installed in a slide groove 15 provided in the supporting column 2. Two positioning plates 13 are symmetrically distributed on both sides of the slider 14. One end of the positioning plate 13 close to the slider 14 is fixedly connected to the slider 14 through a connecting rod 17. A guide rail for accommodating the connecting rod 17 is provided on the side wall of the supporting column 2. The other end of the positioning plate 13 is fixedly connected to the hammer 12 through a connecting rope 16, and the connecting rope 16 is made of elastic material.

[0022] like Figure 1 As shown, a second fixing frame 9 is also fixedly mounted on the base 1, and a rotating member 10 is rotatably mounted on the second fixing frame 9. The other end of the rotating member 10 is fixedly connected to the shaft end of the winding drum of the winch 7.

[0023] The utility model provides an anti-deviating pile driver, and the specific working principle is as follows:

[0024] When in use, the winch 7 and the steel cable 11 drive the hammer 12 to move up and down to drive the pile. In the process of the hammer 12 moving up and down, the slider 14 and the two positioning plates 13 will move synchronously. The connecting rope 16 between the hammer 12 and the two positioning plates 13 will prevent the hammer 12 from deviating, thereby preventing the hammer 12 from easily deviating during the hammering process due to the different softness of the piling ground. The reaction caused by overcoming the deviation of the hammer 12 directly acts on the connecting rope 16. At the same time, the connecting rope 16 is made of elastic material, which can greatly reduce the reaction caused by overcoming the deviation of the hammer 12, thereby preventing the anti-deviating mechanism from being damaged under the reaction force.

[0025] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
