Description

Technical Field

[0001] This utility model relates to the field of piling equipment technology, and in particular to a foundation construction piling equipment. Background Technology

[0002] A pile driver consists of a pile hammer, a pile frame, and auxiliary equipment. The pile hammer is attached to two parallel vertical guide rods (commonly known as a gantry) at the front of the pile frame and is lifted by a hoisting hook. The pile frame is a steel tower structure with a winch at the rear for lifting the pile and pile hammer. A guide frame composed of two guide rods at the front of the pile frame controls the driving direction, ensuring the pile penetrates the ground accurately according to the designed orientation.

[0003] By comparing a foundation construction piling device with patent publication number CN219315726U, it is found that in this solution, the hammer moves up and down and continuously contacts and impacts the ground to carry out piling operations. However, if the soil is too hard, it cannot loosen the soil inside, which may increase the piling time and reduce the efficiency of foundation piling. Utility Model Content

[0004] The purpose of this invention is to provide a foundation construction piling device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions: A foundation construction piling device includes a base plate, a fixing mechanism at the bottom end of the base plate, and a piling mechanism for driving piles for foundation construction, the piling mechanism being located above the base plate. The piling mechanism includes a piling structure for driving piles into the foundation and a lifting structure for lifting the piling structure up and down. The piling structure includes two slide rails symmetrically arranged in the front-to-back direction at the center of the base plate. The slide rails are vertically arranged and have slide rods fixed inside. A lifting plate is slidably installed between the two slide rails and is slidably connected to the slide rods. A piling column is provided at the bottom of the lifting plate, and an auxiliary structure for soil evacuation is provided at the bottom of the piling column.

[0019] In this embodiment, the piling mechanism includes a piling structure for driving piles into the foundation and a lifting structure for lifting the piling structure up and down.

[0020] The piling structure includes two slide rails 201 symmetrically arranged in the front-back direction at the center of the base plate 100. The slide rails 201 are vertically arranged and have a slide rod 202 fixed inside. A lifting plate 203 is slidably installed between the two slide rails 201. The lifting plate 203 is slidably connected to the slide rod 202. A piling column 211 is provided at the bottom of the lifting plate 203. A mounting seat is fixed at the top of the piling column 211. The mounting seat is connected to the lifting plate 203 by bolts. An auxiliary structure for soil dredging is provided at the bottom of the piling column 211.

[0021] The auxiliary structure includes an inner sliding groove 212 set at the bottom of the piling column 211. A lifting seat 213 is slidably installed inside the inner sliding groove 212. A limit spring is connected between the lifting seat 213 and the inner wall of the inner sliding groove 212. A piling block 214 is rotatably installed at the bottom of the lifting seat 213. An arc-shaped groove 215 is opened on the inner wall of the inner sliding groove 212. A guide post 216 is provided between the side wall of the piling block 214 and the arc-shaped groove 215. The guide post 216 is slidably connected to the arc-shaped groove 215 and fixedly connected to the piling block 214. A extraction structure for soil extraction is provided around the piling block 214.

[0022] The insertion and removal structure includes multiple outer sliding grooves 217 formed between the piling block 214 and the piling column 211. The multiple outer sliding grooves 217 are distributed around the center of the piling column 211. A partition 220 is fixed inside the outer sliding groove 217. An insertion cone 218 is slidably installed at the center of the partition 220. A pressing pad 219 is fixed at the top of the insertion cone 218. The pressing pad 219 is made of rubber. A compression spring connects the pressing pad 219 and the partition 220.

[0023] The lifting structure includes a support frame 204 located at the rear of the base plate 100. An upper guide wheel 207 is rotatably mounted on the top of the support frame 204, a front guide wheel 208 is rotatably mounted on the front of the support frame 204, and a take-up roller 205 is rotatably mounted on the rear of the support frame 204. A take-up motor 206 is mounted on the rotating end of the take-up roller 205, and the output end of the take-up motor 206 is fixed to the rotating end of the take-up roller 205 via a coupling. A fixing seat 210 is fixed on the top of the lifting plate 203. The take-up roller 205, upper guide wheel 207, and front guide wheel 208 are all included. A lifting rope 209 is connected between the wheel 208 and the fixed base 210. The lifting structure drives the pile column 211 in the pile driving structure to move up and down continuously, impacting the soil. Each time the pile column 211 impacts the soil, the auxiliary structure drives the pile column 211 to rotate while impacting the soil. This causes the pile column 211 to rub against the soil and generate a circumferential rotational force, which has a certain dispersing effect on the soil, making the soil looser and thus speeding up the pile driving time and improving the efficiency of pile driving.

[0024] Working principle: First, the device is moved to the position to be piled. Then, multiple rotating discs 303 are turned to drive the fixed cone 302 to move downward and insert into the soil to support and fix the device. Then, the winding motor 206 is started to drive the winding roller 205 to rotate and wind up the suspension rope 209. This causes the suspension rope 209 to pull the lifting plate 203 upward, which in turn moves the pile 211 upward to a suitable height. Then, the rotation of the winding roller 205 is stopped. The pile 211 then falls rapidly downward using its own weight, which in turn causes the pile block 214 to fall downward.

[0025] Thus, the pile driving block 214 will first come into contact with the soil and impact it. At the same time, the soil will exert a downward reaction force on the pile driving block 214, pressing it upward. When the pile driving block 214 moves upward, the sliding cooperation between the arc groove 215 and the guide column 216 will cause the pile driving block 214 to rotate. The rotation of the pile driving block 214 and its friction with the soil will generate rotational force, which will have a certain dispersing effect on the soil. Meanwhile, when the lifting seat 213 moves downward, it will press down multiple pressing pads 219 to move downward, driving multiple insertion cones 218 to move downward and insert into the soil, destroying the soil's own structure, making the soil looser, thereby speeding up the pile driving time and improving the efficiency of pile driving.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
