[0001] This utility model relates to the field of support pile construction technology, specifically to a deep foundation pit support drilled cast-in-place pile construction equipment. Background Technology

[0002] In deep foundation pit engineering, bored piles are a common support structure, and their construction involves a variety of specialized equipment. These equipment types are diverse, including drilling equipment for drilling holes in the strata, sludge removal equipment for timely removal of drilling sludge from the holes, hoisting equipment for lowering the reinforcing cage, and grouting equipment for concrete pouring. Among these, the sludge removal equipment plays a crucial role. After drilling, it must efficiently remove the sludge from the holes, providing a clean and well-organized cavity space for subsequent reinforcing cage installation and concrete pouring. This is one of the key steps in ensuring the quality of the bored pile and the stability of the overall support structure.

[0003] Traditional sludge extraction equipment often suffers from low efficiency and discontinuous discharge when extracting sludge. At the same time, the power transmission between its drive and actuator lacks effective guidance and stabilization measures, which can easily lead to unstable equipment operation, aggravate the wear of key moving parts, and affect the overall durability of the equipment.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 As shown, this utility model provides a technical solution: A deep foundation pit support drilled pile construction device includes a support platform 101. Two first support blocks 102 are symmetrically installed on one side of the top of the support platform 101 by bolts. Piston cylinders 103 are fixedly installed on the top of the first support blocks 102 respectively. Two output one-way valves 104 are symmetrically installed on the top of the piston cylinders 103 respectively. Two input one-way valves 105 are symmetrically installed on the side of the piston cylinders 103 respectively. Moving pistons 106 are provided inside the piston cylinders 103 respectively. A cover 107 is bolted to one end of the piston cylinders 103 respectively. The cover 107 is fixedly installed on the telescopic cylinder 108 respectively. The other end of the telescopic cylinder 108 is fixed to the guide box 109 respectively. A guide block 110 is slidably installed inside the guide box 109. A telescopic rod 111 is fixedly installed on the side of the guide block 110 facing the telescopic cylinder 108. The telescopic rod 111 passes through the guide cylinder and into the piston cylinder 103 to connect with the moving pistons 106.

[0018] The above scheme provides a basic installation platform and stable support for the entire equipment through a support platform. The first support block is used to install and fix the piston cylinder, which forms the core cavity for sludge pumping. The output check valve controls the sludge to be discharged unidirectionally from the inside of the piston cylinder to the external pipeline, and the input check valve controls the sludge to be drawn into the piston cylinder from the outside. The piston reciprocates within the piston cylinder to change the internal volume, thereby achieving sludge suction and discharge. The piston cylinder end is sealed with a cover and connected to a telescopic cylinder. The telescopic cylinder provides guidance and protection for the telescopic rod to maintain motion stability. The guide box provides an installation base and guide track for the internal moving parts. The guide block slides within the guide box to transmit the power of the drive mechanism. The telescopic rod connects the moving piston and the drive mechanism to transmit reciprocating motion.

[0019] In this embodiment, preferably, the guide box 109 is symmetrically installed on one side of the drive box 112, and a second support block 113 is fixedly installed at the bottom of the drive box 112. The second support block 113 is installed on the other side of the top of the support platform 101 by bolts.

[0020] The above scheme uses symmetrical installation of guide boxes to evenly transmit the power of the drive mechanism to the piston cylinders on both sides, the drive box to accommodate and support the core transmission mechanism, and the second support block to firmly install the drive box on the support platform.

[0021] In this embodiment, preferably, the top of the drive box 112 protrudes upward to form a planar boss 114, a reducer 115 is bolted to one side of the top of the planar boss 114, and a drive motor 116 is bolted to the other side of the top of the planar boss 114.

[0022] The above scheme provides a flat mounting surface for the upper components by forming a flat boss by protruding upward at the top of the drive box. The reducer receives the power from the drive motor and reduces the speed while increasing the output torque. The drive motor provides the original rotational power for the entire sludge extraction system.

[0023] In this embodiment, preferably, the input shaft of the reducer 115 is connected to the output shaft of the drive motor 116 via a coupling, and the output shaft of the reducer 115 is provided with a drive pulley 118, on which a transmission belt 119 is movably mounted.

[0024] The above scheme receives power from the drive motor through the input shaft of the reducer, connects the drive motor and the reducer through a coupling to transmit torque and compensate for installation errors, outputs rotational power through the output shaft of the drive motor, transmits the power output by the reducer to the transmission belt through the drive pulley, and transmits the power remotely from the drive pulley to the transmission pulley through the transmission belt.

[0025] In this embodiment, preferably, a drive shaft 120 is installed inside the drive box 112 via a bearing. One end of the drive shaft 120 extends through to the outside of the drive box 112 and is provided with a drive pulley 121. The drive pulley 121 is movably connected to the other end of the drive belt 119.

[0026] The above scheme uses a drive shaft mounted inside the drive box via bearings to provide rotational support. The drive shaft, as the core drive shaft component, transmits power to the eccentric mechanism. One end of the drive shaft passes through the outside of the drive box to connect to the drive pulley. The drive pulley receives power from the drive belt and drives the drive shaft to rotate.

[0027] In this embodiment, preferably, a partition disk 122 is fixedly installed in the middle of the transmission shaft 120 and inside the drive box 112, and eccentric disks 123 are symmetrically installed on both sides of the partition disk 122 on the transmission shaft 120, and the two eccentric disks 123 are biased in opposite directions.

[0028] The above scheme uses a partition plate fixedly installed in the middle of the drive shaft to divide the shaft into two installation areas. Eccentric plates are symmetrically installed on both sides of the partition plate on the drive shaft to convert the rotational motion into eccentric motion. The two eccentric plates with opposite bias directions achieve the reciprocating motion of the two piston cylinders with opposite phases.

[0029] In this embodiment, preferably, a collar 124 is mounted on the outer side of the eccentric disk 123 via bearings, a tapered plate 125 is fixedly mounted on one side of the collar 124, and the other end of the tapered plate 125 is mounted in the guide block 110 via bearings.

[0030] The above scheme converts sliding friction into rolling friction by mounting a collar on the outside of the eccentric disk via a bearing to reduce wear. A tapered plate is fixedly mounted on one side of the collar to connect with and drive the guide block. The other end of the tapered plate is mounted in the guide block via a bearing to achieve hinge and transmit reciprocating thrust.

[0031] In this embodiment, when the deep foundation pit support drilled pile construction equipment is in use, the drive motor 116 starts, and its output high-speed rotational power is completely transmitted to the reducer 115 through the coupling. The reducer 115 undertakes the key task of speed reduction and torque increase. It outputs the adjusted rotational power with greater torque to the drive pulley 118 on its output shaft. The drive pulley 118 transmits the power remotely to the transmission pulley 121 installed at one end of the transmission shaft 120 through the transmission belt 119 surrounding it, thereby driving the entire transmission shaft 120 to rotate stably inside the drive box 112 with the support of bearings.

[0032] The drive shaft 120 serves as the central hub for power distribution. A partition plate 122 fixedly mounted on the shaft divides the shaft into two working areas, each with an eccentric plate 123 installed in completely opposite directions. When the drive shaft 120 rotates, the two eccentric plates 123 perform synchronous but opposite-phase eccentric rotational motions. Each eccentric plate 123 has a collar 124 mounted on its outer side via a set of bearings. This design converts the eccentric rotational motion of the eccentric plate 123 into a quasi-linear motion tendency of the collar 124. The conical plate 125, fixedly connected to the collar 124, moves accordingly. The other end of the conical plate 125 is connected to the guide block 110 inside the guide box 109 via a bearing. Since the guide block 110 is constrained inside the guide box 109 and can only slide linearly, the rotational motion of the eccentric plate 123 is ultimately precisely converted into highly stable reciprocating linear motions with opposite phases by the two guide blocks 110 within their respective guide boxes 109 via the collar 124 and the conical plate 125.

[0033] The reciprocating linear motion of each guide block 110 directly drives the telescopic rod 111, which is fixedly connected to it, to perform synchronous telescopic motion. The telescopic rod 111 passes through the telescopic cylinder 108, which serves as a guide and protector, and passes through the sealed cover 107, eventually penetrating into the piston cylinder 103 and connecting with the moving piston 106. Thus, the reciprocating motion of the guide block 110 is transmitted to the moving piston 106 without loss, enabling it to perform a precise reciprocating pumping stroke inside the piston cylinder 103.

[0034] In a complete working cycle, when the moving piston 106 on one side is pushed forward, the volume of the piston cylinder 103 in front of it decreases, and the pressure increases, forcing the sludge in that chamber to open the output check valve 104 located in front of the top of the piston cylinder 103 and be discharged; at the same time, the volume of the chamber behind the piston increases, forming a negative pressure, thereby drawing open the input check valve 105 located behind the side of the piston cylinder 103, drawing in external sludge to replenish it; conversely, when the moving piston 106 retracts backward, its The rear chamber is pressurized, and the sludge that has just been sucked in is discharged through the output check valve 104 at the rear of the top of the piston cylinder 103; while the front chamber is under negative pressure, and new sludge is sucked in again through the input check valve 105 at the front of the side of the piston cylinder 103; since the two piston cylinders 103 are driven by eccentric discs 123 with opposite phases, their sludge suction and discharge strokes are staggered and complementary, which enables the entire system to achieve almost continuous sludge suction and discharge, greatly improving the sewage discharge efficiency and the stability of operation.

[0035] Throughout the process, the support platform 101 and its first support block 102 and second support block 113 provide a solid foundation for the entire equipment; the precise fit between the guide box 109 and the guide block 110 ensures the straightness and stability of the movement of the telescopic rod 111 and the piston, avoiding wear and jamming caused by lateral forces. The coordinated operation of all one-way valves strictly guarantees the unidirectional flow of sludge, preventing backflow, thus forming a highly efficient, reliable, and continuous sewage discharge system for deep foundation pit support drilled pile construction.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
