Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pile hole excavation equipment, and in particular to a pile driving tool for geotechnical engineering. Background Technology
[0002] Rotary drilling buckets are specialized tools for excavating pile holes. They are mostly used with rotary drilling rigs. The bucket is cylindrical in shape and made of high-strength steel. It has an openable bucket door at the bottom and wear-resistant teeth welded to the edges.
[0003] During operation, the drilling rig drives the rotary bucket to rotate, and the bucket teeth cut into the soil or rock layer, rolling the excavated soil into the bucket. After it is full, the bucket is lifted, and the bottom plate automatically closes to prevent material leakage. Once on the ground, the bottom plate is opened by the unlocking lever mechanism to unload the soil. The unlocking lever mechanism generally adopts a double hook type or a hook-and-gate type structure. The hook-and-gate type structure has higher strength than the double hook type structure, but during operation, the soil is squeezed into the gaps. Especially with clay and silt, which are sticky, the soil is easy to get stuck in the gate-type buckle. After the bottom plate is opened to discharge the soil, the upper hook of the unlocking lever mechanism cannot be engaged in the gate-type buckle after the bottom plate is reset, thus affecting the normal closing of the bottom plate. Utility Model Content
[0004] The purpose of this utility model is to provide a piling tool for geotechnical engineering, which has a base plate equipped with a buckle cleaner, including a mounting base, pressure plate, push rod, and push block, and works in conjunction with a Y-shaped fixing rod inside the bucket. When the base plate is closed, the soil in the buckle is automatically cleaned, ensuring that the hook is engaged, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A piling tool for geotechnical engineering includes a bucket body, a bottom plate hinged to the bottom of the bucket body, a plurality of rotary drilling teeth fixedly connected to the bottom of the bottom plate, a fastener fixedly connected to one side of the bottom plate, a fastener cleaner disposed on the bottom plate near the fastener, the fastener cleaner further including two mounting seats, a base fixedly connected between the two mounting seats, the base fixedly mounted on the bottom plate, a pressure plate movably connected inside the mounting seat, a push rod inserted through one side of the mounting seat, a push block fixedly connected to one end of the push rod, a connecting square tube fixedly connected to the top of the bucket body, a fixing beam fixedly mounted on one side of the connecting square tube, and an unlocking pressure rod mechanism disposed between the fixing beam and the bucket body.
[0007] As a further preferred embodiment of this utility model, a Y-shaped fixing rod is fixedly connected to the inner side of the bucket located above the buckle. The Y-shaped fixing rod can provide pressure to the pressure rod, thereby causing the two pressure plates to move down in their respective mounting seats, thereby pushing the push rod to move horizontally.
[0008] As a further preferred embodiment of this utility model, the mounting base is provided with a mounting groove, and the longitudinal section of the mounting groove is inverted T-shaped.
[0009] As a further preferred embodiment of this utility model, limit blocks are fixedly connected to both sides of the pressure plate. The bottom side of the pressure plate and the limit block is provided with a slope and a slider is fixedly connected. The pressure plate is inserted into the corresponding limit block through the limit block. Multiple compression springs are also clamped at the bottom of the pressure plate. The pressure plate with the slope at the bottom is inserted into the mounting groove, and the initial position of the pressure plate is achieved by means of the force of the compression spring.
[0010] As a further preferred embodiment of this utility model, a pressure-bearing rod is fixedly connected between the two pressure plates, and the pressure-bearing rod can cooperate with the mounting groove to press down the two pressure plates simultaneously.
[0011] As a further preferred embodiment of this utility model, one end of the push rod is provided with a slope surface corresponding to the bottom of the pressure plate and a sliding groove is provided, and the sliding groove is slidably connected to the corresponding slider. The other end of the push rod is fixedly installed with a support block, and a connecting rod is fixedly connected between the two push rods. By sliding one end of the push rod to the slider at the bottom of the pressure plate through the sliding groove, the horizontal movement of the push rod can be realized, so that the push block at one end of the push rod can clean the mud blocked in the buckle.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] In this utility model, a buckle cleaner is provided on the bottom plate, and the buckle cleaner is composed of a mounting base, a pressure plate, a push rod, a push block and other structures. With the help of the Y-shaped fixing rod set on the inside of the bucket, it can automatically flush out and disperse the soil blocking the buckle when the bottom plate is closed, so that the upper hook of the unlocking pressure rod mechanism can be properly locked into the buckle, reducing the intensity of personnel operation and improving the efficiency of pile hole excavation.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] like Figures 1-5 As shown, the present invention provides a piling tool for geotechnical engineering, including a bucket body 1, a bottom plate 2 hinged to the bottom of the bucket body 1, a plurality of rotary drilling teeth 3 fixedly connected to the bottom of the bottom plate 2, a buckle 4 fixedly connected to one side of the bottom plate 2, a buckle cleaner 5 provided on the bottom plate 2 near the buckle 4, the buckle cleaner 5 also includes two mounting seats 6, a base 7 fixedly connected between the two mounting seats 6, the base 7 fixedly installed on the bottom plate 2, a pressure plate 8 movably connected inside the mounting seat 6, a push rod 9 inserted through one side of the mounting seat 6, a push block 10 fixedly connected to one end of the push rod 9, a connecting square tube 11 fixedly connected to the top of the bucket body 1, a fixing beam 12 fixedly installed on one side of the connecting square tube 11, and an unlocking pressure rod mechanism 13 provided between the fixing beam 12 and the bucket body 1.
[0022] like Figures 2-3 As shown, a Y-shaped fixing rod 20 is fixedly connected to the inner side of the bucket body 1 located above the buckle 4. The Y-shaped fixing rod 20 can provide pressure to the pressure rod 17, thereby causing the two pressure plates 8 to move down in the corresponding mounting seats 6, thereby pushing the push rod 9 to move horizontally.
[0023] like Figures 3-5As shown, the mounting base 6 has a mounting groove 14, the longitudinal section of which is an inverted T-shape. Limiting blocks 15 are fixedly connected to both sides of the pressure plate 8. A slope is provided on one side of the bottom of the pressure plate 8 and the limiting block 15, and a slider 21 is fixedly connected thereto. The pressure plate 8 is inserted into the corresponding limiting block 15 through the limiting block 15. Multiple compression springs 16 are also fitted at the bottom of the pressure plate 8. The pressure plate 8 with its sloped bottom is inserted into the mounting groove 14, and the initial positioning of the pressure plate 8 is achieved by the force of the compression springs 16. A pressure-bearing device is fixedly connected between the two pressure plates 8. Rod 17, bearing rod 17 can work with mounting groove 14 to press down two pressure plates 8 simultaneously. One end of push rod 9 is provided with a slope corresponding to the bottom of pressure plate 8 and a sliding groove 22 is provided. The sliding groove 22 is slidably connected to the corresponding slider 21. The other end of push rod 9 is fixedly installed with support block 19. A connecting rod 18 is fixedly connected between the two push rods 9. By sliding one end of push rod 9 to the slider 21 at the bottom of pressure plate 8 through sliding groove 22, the horizontal movement of push rod 9 can be realized, so that push block 10 at one end of push rod 9 can clean the soil blocked in buckle 4.
[0024] It should be noted that this utility model is a pile driving tool for geotechnical engineering. The bottom of the bucket body 1 is hinged to the bottom plate 2. The rotary digging teeth 3 at the bottom of the bottom plate 2 rotate with the bucket body 1 and cut into the soil. After the soil enters the bucket body 1, the bottom plate 2 closes to prevent material leakage. The buckle 4 on the bottom plate 2 cooperates with the unlocking pressure rod mechanism 13 on the inside of the bucket body 1 to realize the opening and closing control of the bottom plate 2. When the bucket body 1 finishes discharging soil, its bottom plate 2 closes back to the bucket body 1. When the bottom plate 2 is closed, the Y-shaped fixing rod 20 presses down the bearing rod 1. 7. Push the pressure plate 8 down along the mounting groove 14. The bottom slope of the pressure plate 8 contacts the slope of one end of the push rod 9. Through the sliding cooperation of the slider 21 and the sliding groove 22, the vertical pressure is converted into a horizontal thrust, causing the push rod 9 to drive the push block 10 to move towards the buckle 4, breaking up the soil blocking the buckle 4. When the bucket body 1 cooperates with the bottom plate 2 and the rotary drilling teeth 3 to perform rotary drilling operations, the two push blocks 10 are placed in the buckle 4, which can prevent the soil from completely filling the buckle 4 and further reduce the probability of the buckle 4 being blocked.
