Description

Technical Field

[0001] This utility model relates to the field of trench wall reinforcement construction technology, and in particular to a dual-wheel mixing drilling machine. Background Technology

[0002] Most existing projects use cement-soil mixing walls for trench wall reinforcement. However, because the cross-section of the three-axis mixing pile is a sawtooth three-circle shape, the soil used to reinforce the trench wall already has a certain strength when the diaphragm wall is being constructed. The trenching machine cannot completely mill the sawtooth three-circle reinforced soil cross-section into a flat surface. After the diaphragm wall is cast, the surface is wavy. At the same time, due to the inherent characteristics of the machinery, as the reinforcement depth increases, it is difficult to control the verticality of the three-axis mixing machine, which can easily lead to pile deviation, resulting in trench misalignment and affecting the verticality accuracy and quality. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dual-wheel mixing drill.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

A frame is mounted on one side of the drilling rig base, and a drill rod is mounted on one side of the frame. A lift corresponding to the drill rod is mounted on the frame. A milling machine is mounted at the bottom of the drill rod, and an inclinometer is mounted on the milling machine. The milling machine has at least two sets of milling wheels. The bottom of the frame is hinged to the drilling rig base. A connecting frame is mounted on one side of the middle of the frame. A stabilizing rod is mounted between the connecting frame and the drilling rig base. A steel cable is connected to the top of the drill rod. A winch is mounted on one side of the engineering vehicle. A suspension bracket is mounted on the top of the frame, and a traction wheel is mounted on the suspension bracket. The steel cable is supported on the traction wheel.

[0006] Preferably, the drilling rig base is equipped with a lifting device at its bottom, and the engineering vehicle is equipped with a counterweight on one side.

[0007] Preferably, the milling wheel rotation axis is arranged horizontally, the engineering vehicle is equipped with an engineering display, and the inclinometer is connected to the engineering display via a data cable.

[0012] 1.

[0019] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] Reference Figure 1-4 A dual-wheel mixing drilling rig includes an engineering vehicle 7 and a drilling rig base 71. The bottom of the drilling rig base 71 is equipped with a lifting device for controlling the swing of the drilling rig base 71 and adjusting the pitch or tilt angle. A counterweight is provided on one side of the engineering vehicle 7 to ensure the balance of the engineering vehicle 7. A frame 1 is provided on one side of the drilling rig base 71. The bottom of the frame 1 is hinged to the drilling rig base 71. A connecting frame 2 is provided on one side of the middle of the frame 1. A stabilizing rod 5 is provided between the connecting frame 2 and the drilling rig base 71. The stabilizing rod 5 is a hydraulic telescopic rod that can extend and retract to adjust the verticality of the frame 1, or cooperate with the drilling rig base 71 to lift and tilt the frame 1 for easy movement of the engineering vehicle 7. Universal connectors are provided at both ends of the stabilizing rod 5. The universal connectors are respectively set with the connecting frame 2 and the drilling rig base 71 to facilitate the extension and retraction adjustment of the stabilizing rod 5.

[0021] A drill rod 4 is provided on one side of the frame 1. A lifting machine corresponding to the drill rod 4 is provided on the frame 1. The lifting machine controls the drill rod 4 to move up and down. A milling machine 6 is provided at the bottom of the drill rod 4. An inclinometer is provided on the milling machine 6. At least two sets of milling wheels are provided on the milling machine 6. The milling wheel rotation axis is set in the horizontal direction. The two sets of milling wheels form a rectangular section of cement-soil mixing pile by rotating and stirring in the horizontal axis, rather than forming a cylindrical cement-soil mixing pile by rotating vertically with a single or multi-axis mixing drill bit.

[0022] The engineering vehicle 7 is equipped with an engineering display. The inclinometer and the engineering display are connected by a data cable, and the data can be uniformly summarized in the engineering display on the dashboard of the driver's cab. Compared with traditional three-axis mixing piles, SMW method piles and other processes, it can better control the verticality of the overall construction.

[0023] A steel cable 3 is connected to the top of the drill rod 4. A guide wheel corresponding to the steel cable 3 is provided on one side of the connecting frame 2 to adjust the direction of force on the steel cable 3 and facilitate the erection of the steel cable 3. A winch 8 is provided on one side of the engineering vehicle 7. One end of the steel cable 3 is set in correspondence with the winch 8 and the winch 8 is used to wind up the steel cable 3.

[0024] The top of the frame 1 is equipped with a suspension bracket 11, and a traction wheel 12 is installed on the suspension bracket 11. The steel cable 3 is mounted on the traction wheel 12. The top of the drill rod 4 is provided with a wire-concealing groove 41. One end of the steel cable 3 is connected to the bottom of the wire-concealing groove 41. The steel cable 3 pulls the drill rod 4, controls the top of the drill rod 4, and cooperates with the lifting machine to lift it. The upper and lower parts of the drill rod 4 are subjected to force at the same time, which improves the stability of the drill rod 4 and avoids uneven force on the drill rod 4, which may cause tilting. This effectively reduces the working pressure of a single lifting machine and extends the service life of the lifting machine.

[0025] A limiting block 10 is provided on one side of the suspension bracket 11. The bottom of the limiting block 10 is chamfered or flared to facilitate quick alignment and insertion of the drill rod 4 after it is disengaged. The drill rod 4 and the limiting block 10 slide in contact. A notch corresponding to the cable hiding groove 41 is provided on one side of the limiting block 10 to facilitate the passage of the steel cable 3.

[0026] In this embodiment, the underground continuous trench wall is reinforced. The engineering vehicle 7 travels to the construction site, adjusts and fixes the drilling rig base 71, the stabilizer 5 supports the frame 1 to ensure that the frame 1 is set vertically, the trenching machine 6 is debugged, and different types of milling wheel cutters are selected according to the geological conditions to ensure that the milling wheel rotation axis is set horizontally. The trenching machine 6 works, the milling wheel rotates, and the horizontal axial rotation mixing method forms a rectangular trench section of cement-soil mixing pile. The underground continuous trench wall is reinforced through the cement-soil mixing wall.

[0027] During construction, drill rod 4 moves up and down, engineering vehicle 7 moves horizontally, and inclinometer detects the angle of milling machine 6 in a timely manner, so that construction personnel can make adjustments through stabilizer 5 to ensure that the milling wheel processing surface is in a vertical plane, thus achieving the reinforcement of underground continuous trench walls. Because drill rod 4 is long, it is not easy to keep stable. If it is supported only by the hoist, the requirements of the hoist are high and the load is heavy. The drill rod 4 is unevenly stressed and is prone to shaking, which affects the vertical accuracy of milling machine 6. Therefore, steel cable 3 is used to suspend drill rod 4 to ensure that drill rod 4 is stably erected and kept stable, avoiding uneven stress at the top, which may cause shaking or tilting. At the same time, it reduces the load on the hoist and extends the service life of the equipment.
