Description

Technical Field

[0001] The utility model relates to the technical field of grouting equipment, in particular to a karst geological rotary drilling pile leakage prevention grouting equipment. Background Art

[0002] Rotary pile grouting equipment is a professional mechanical equipment that plays a key role in construction projects. This equipment is usually composed of multiple important parts, including power system, pumping system, control system and grouting pipeline. The power system provides a strong driving force for the operation of the equipment, ensuring that it can work stably under various working conditions; the pumping system can accurately transport concrete or other grouting materials to the designated location.

[0003] In special geological areas such as karst, there may be a large number of caves and cracks in the strata. During the grouting process, the injection components come into contact with the caves and cracks, resulting in damage and leakage of the injection components. The most vulnerable parts of the injection components are joints, valves, pipe connections, etc. Leakage will reduce the grouting pressure, resulting in hollow and loose areas inside the pile body, thereby reducing the bearing capacity and stability of the pile body and affecting its supporting role in the building or structure. Utility Model Content

[0004] The utility model solves the deficiencies of the prior art and provides a karst geological rotary drilling pile anti-leakage grouting device which protects injection component joints and pipeline connections and prevents injection components from being damaged and leaking.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a karst geological rotary drilling pile leakage prevention grouting equipment, including a support assembly, a mixing drum, a storage hopper, an auxiliary assembly and an injection assembly, the support assembly including a support frame, a mixing drum, a storage hopper, an auxiliary assembly and an injection assembly are installed in the support frame, the mixing drum is provided with a feed port and a discharge port, the outlet of the storage hopper is connected to the feed port of the mixing drum, the injection assembly includes a conduit and an extension pipe, the conduit is installed on the support frame through a connecting plate, the inlet end of the conduit is connected to the discharge port of the mixing drum, the conduit and the extension pipe are coaxially connected through a connecting joint, and a retractable extension cylinder is coaxially sleeved on the outside of the conduit, the top end of the extension cylinder is fixed on the connecting plate, and the bottom of the extension cylinder is driven to retract along the axial direction of the conduit by the auxiliary assembly, and the retractable length of the extension cylinder is sufficient to cover the conduit, extension pipe and connecting joint after the extension cylinder is extended.

[0006] In this embodiment, a stirring chamber connected to the feed port and the discharge port is provided in the stirring drum. A stirring shaft driven by a motor is installed in the stirring chamber between the feed port and the discharge port, and a stirring blade is installed on the stirring shaft.

[0007] In this embodiment, an outer cover is fixed to the outside of the support frame to protect the internal components of the support frame.

[0008] In this embodiment, a control switch for controlling the opening and closing of the driving motor is installed on the outer cover.

[0009] In this embodiment, the auxiliary component includes a driving mechanism, a gear, a rack, a rotating rod and a movable plate. The driving mechanism is mounted on the connecting plate through an auxiliary bracket. The output end of the driving mechanism is coaxially connected to the rotating rod. The rotating rod is rotatably transferred to the auxiliary bracket. The central axis of the rotating rod is arranged perpendicular to the central axis of the catheter. A gear is coaxially fixed on the rotating rod. The rack is slidably transferred to the auxiliary bracket. The rack is arranged parallel to the catheter. The rack is engaged with the gear. One end of the movable plate is fixedly connected to the rack, and the other end is fixedly connected to the extension tube.

[0010] In this embodiment, the driving mechanism includes a driving motor, a pulley and a belt. The pulley includes a driving pulley and a driven pulley. The driving pulley and the driven pulley are connected by a belt to achieve synchronous movement. The driving pulley and the driven pulley are both rotatably assembled on the support frame. The driven pulley is coaxially connected to the rotating rod, and the output end of the driving motor is connected to the driving pulley.

[0011] With the above structure, the device has the following advantages:

[0012] 1. The present application can protect the components installed in the support frame through the support frame, and reduce the probability of collision with rock walls and stones to the internal mixing drum when the equipment is working in karst geological conditions.

[0013] 2. When the device is working, the auxiliary component drives the extension tube to extend to cover the conduit, the extension tube and the connecting joints between the two, thereby protecting the pipeline and the connecting joints.

[0014] 3. The auxiliary components of this device are driven by a drive motor. When the drive motor is started to rotate forward, the belt drives the rotation of the pulley at the bottom, the pulley drives the rotation of the rotating rod, and the rotating rod drives the movable plate to move, thereby pushing the extension tube to extend, so that the extension tube is protected outside the connection position of the catheter and the extension tube, to prevent the extension tube, the catheter, and the connection joint from being damaged by the rock wall and protruding stones and causing leakage; when the grouting is completed, the control switch is controlled to start the drive motor to rotate in the reverse direction, thereby driving the extension tube to retract, which can facilitate the cleaning and maintenance of the connection position of the catheter and the extension tube, and also facilitate the replacement of extension tubes of different models.

[0015] In summary, this device assists the injection assembly to operate efficiently. During the entire grouting process, it adds strict protection measures for the injection assembly, and avoids leakage that may occur during the grouting process to the greatest extent. It not only effectively reduces the waste of grouting materials and reduces engineering costs, but also significantly improves the quality and efficiency of grouting, making the structure of the rotary bored pile more stable and reliable, but also reduces pollution to the construction environment and reduces the workload of subsequent cleaning and repair.

The outlet of the storage hopper 5 is connected to the feed port of the mixing drum 2, and a motor-driven stirring shaft 9 is installed in the stirring chamber between the feed port and the discharge port. A stirring blade 8 is installed on the stirring shaft 9. The injection assembly 7 includes a conduit 71 and an extension tube 72. The conduit 71 is installed on the support frame 11 through a connecting plate 73. The inlet end of the conduit 71 is connected to the discharge port of the mixing drum 2. The conduit 71 and the extension tube 72 are coaxially connected through a connecting joint. A retractable extension tube 74 is coaxially sleeved on the outside of the conduit 71. The top of the extension tube 74 is fixed on the connecting plate 73, and the bottom of the extension tube 74 is driven by the auxiliary component 6 to retract along the axial direction of the conduit 71. The retractable length of the extension tube 74 is sufficient to cover the conduit 71, the extension tube 72 and the connecting joint between the two after the extension tube 74 is extended.

[0025] The auxiliary assembly 6 includes a driving mechanism, a gear, a rack, a rotating rod 62 and a movable plate 64. The driving mechanism is installed on the connecting plate 73 through the auxiliary bracket 61. The output end of the driving mechanism is coaxially connected to the rotating rod 62. The rotating rod 62 is rotatably transferred to the auxiliary bracket 61. The central axis of the rotating rod 62 is perpendicular to the central axis of the guide tube 71. A gear is coaxially fixed on the rotating rod 62. The rack is slidably transferred to the auxiliary bracket 61. The rack is arranged parallel to the guide tube 71. The rack is meshed with the gear. One end of the movable plate 64 is fixedly connected to the rack, and the other end is fixedly connected to the extension tube 74.
