Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction equipment technology, and in particular to a pile driver support with adjustable mixing depth. Background Technology

[0002] In the field of pile foundation construction, especially in the construction of deep mixing piles (such as cement-soil mixing piles, high-pressure jet grouting piles, etc.), the precise control of the mixing depth directly affects the pile quality and the foundation treatment effect. With the improvement of large-scale construction equipment production, a pile driver support with adjustable mixing depth has emerged to solve the problem of adjusting the mixing depth of the pile driver.

[0003] Currently, pile drivers and supports are mainly used in deep mixing pile construction, such as soft soil foundation reinforcement. They are suitable for soft soil foundation treatment in highways, railway subgrades, ports and wharves, etc., requiring precise control of cement admixture and mixing range. They are also used in seepage prevention wall construction, for deep mixing of seepage prevention walls in water conservancy projects, landfills, etc., requiring continuous and uniform control of mixing depth.

[0004] Currently, common pile driver supports still have defects. For example, they are prone to slippage when subjected to construction vibration or load changes, which leads to deviations in the mixing depth, affecting the uniformity of pile formation and the mixing accuracy. Also, the mixing process often causes mud to splash onto the shaft surface, resulting in adverse reactions in the shaft. Therefore, a pile driver support with a reinforced fixing structure is needed to cope with various negative impacts during construction. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a pile driver support with adjustable mixing depth, which aims to improve the problem of deviation in mixing depth and accuracy caused by adverse effects of vibration and load changes during construction.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pile driver support with adjustable mixing depth, comprising a main board, a frame platform fixedly connected to the upper surface of the main board, a fixing plate fixedly connected to the outer wall of the frame platform, a linear guide rail fixedly connected to the inner wall of the fixing plate, a power unit slidably connected to the outer wall of the linear guide rail, and a movable support assembly provided on the outer wall of the frame platform. The movable support assembly includes a collar, the inner wall of which is fixedly connected to the outer wall of a fixed plate. A grounding shaft is slidably connected to the inner wall of the collar. A retaining ring is slidably connected to the upper outer wall of the grounding shaft. A connecting frame is fixedly connected to the outer wall of the retaining ring. One end of the connecting frame is fixedly connected to the outer wall of the power unit.

[0010] Furthermore, a cable is fixedly connected to the inner wall of the reel, the outer wall of the cable is slidably connected to the inner wall of the wheel, and one end of the cable is fixedly connected to the upper surface of the power unit.

[0011] Furthermore, a fixing block is fixedly connected to the outer wall of the motherboard, and a support rod is connected to the outer wall of the fixing block.

The linear guide rail is installed on the frame and slidably connected to the power machine. A grounding shaft and a movable foot are added in front of the frame. When the stirring shaft works downward, the grounding shaft moves downward synchronously until the front end is inserted into the ground. The movable foot contacts the ground. Therefore, the accuracy can be improved by the guiding nature of the linear guide rail. The foot in contact with the ground and the grounding shaft inserted into the ground provide the stability of the overall structure, thus achieving the function of anti-vibration and anti-displacement.

There are double door structures on both the left and right sides, which further increases the flexibility of the mudguards. One of the two second mudguards is equipped with a bushing and the other with a pin ring. The opening and closing of the mudguards is completed by inserting and pulling the pin ring. The main function of the mudguards is to prevent the mud generated by the mixing shaft from splashing onto the shaft and other critical parts during operation, which would reduce the service life.

[0021] Working principle: The bottom of the main board 1 is equipped with a track 19. The track 19 moves by cooperating with the outer plate 17 through the roller 18. The upper surface of the main board 1 is connected to the platform 2. The main board 1 uses the pull rod 15 and the connecting ring 16 to reinforce and fix the platform 2. The main board 1 is equipped with a counterweight 13 to balance the weight. Because the platform 2 is very high, support rods 21 are installed at the four corners of the main board 1. The support rods 21 are fixedly connected to the main board 1 with the fixing block 20. The platform 2 has a wheel frame 3 and a cable wheel 5. The wheel frame 3 and the cable wheel 5 are connected by a wheel axle 4. The cable 6 is placed in the groove of the cable wheel 5 and is slidably fixed.

The upper end of the cylindrical shaft 31 is connected to a top plate 29, and the lower end is connected to a foot 33. A spring 32 is sleeved on the outer wall. When the power machine 9 is working downward, the head of the grounding shaft 24, which is slidably connected to it, is inserted into the ground. The front foot 33 applies pressure to the ground through the spring 32 and the sleeve 30 to stabilize the pile driver support during the mixing operation and reduce the risk of structural instability during operation. The first baffle 34 and the second baffle 35 form a foldable mudguard. One side of the first baffle 34 is connected to the frame 2, and the other side is connected to the second baffle 35 through a hinge 36.
