Description

Technical Field

[0001] The utility model belongs to the technical field of casing hole-forming devices, and in particular relates to an anchor cable casing hole-forming device. Background Art

[0002] In foundation pit support engineering, anchor cable is an important supporting material, which is mainly used to fix and support the soil and structures around the foundation pit to prevent ground collapse and instability of the foundation pit. Anchor cable can be fixed in rock mass or deep soil layer to fix the soil together to prevent soil tilt and collapse, and improve the stability of foundation pit support. In foundation pit support engineering, deep foundation pit support structure, such as deep foundation pit support pile, support wall, etc., is often required. Anchor cable can be connected with the support structure to enhance the stability and tensile strength of the support structure. Anchor cable can share the groundwater pressure and reduce the impact of groundwater on the support structure. Anchor cable can be fixed on buildings or pipelines to prevent displacement or damage due to foundation pit construction. In actual operation, many isolated rocks and the like will be encountered, and the angle may be slightly offset. To ensure that the anchor cable can smoothly reach the designed depth and penetrate completely, a directional mechanism will be set on the casing hole-making device to limit the push of the drill bit along the predetermined route to avoid the deviation of the drill bit, so as to smoothly reach the predetermined depth position.

[0003] Patent application number 202022852869.2 discloses an anchor cable casing hole forming device, including a base, a second rotating shaft and a second sliding groove, a first limit block is arranged above the base, a first sliding groove is opened on the inner side of the first support rod, second limit blocks are arranged on both sides of the second support rod, the second rotating shaft is arranged above the second support rod, a third rotating shaft is arranged below one end of the fixed platform, first fixed blocks are arranged on both sides of the third support rod, the second sliding groove is opened on the front surface of the fixed platform, and a second limit rod is arranged on the inner side of the second fixed block. The utility model enables the second support rod to slide and move up and down by setting the first sliding groove.

[0004] Although the above technical solution can position the motor and the drill bit, due to the lack of a positioning structure for the anchor casing, the anchor casing is prone to misalignment during the hole-forming process. At the same time, since the long drill bit is prone to bending during the processing and causing processing deviations, the accuracy of the anchor casing hole-forming is poor. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of the present invention are:

The anchor cable sleeve body is inserted into the mounting frame, and the screw is driven to rotate by a knob. The two screws rotate synchronously through gears and toothed belts, and the clamping plates move toward each other during the rotation process to clamp and fix the anchor cable sleeve body. Since the two clamping plates move synchronously, the anchor cable sleeve body is always fixed at the center position of the mounting frame, and the anchor cable sleeve body is clamped and fixed by the clamping plates in the mounting frame. The positioning mechanism is used to position the drill bit and the sleeve, so as to avoid the deviation of the drill bit and improve the stability of the anchor cable sleeve body during hole forming processing.

[0019] By symmetrically fixing push rods on the side walls of the sliding frame, when the sliding frame is moved by the handle, the push rods make the elastic band and the positioning ring move synchronously through the connecting ring. Since the tension of the two elastic bands is the same, the elastic band and the positioning ring assist in positioning the drill bit's rotation. At the same time, when the drill bit is inserted into the anchor cable casing body, the side wall of the anchor cable casing body squeezes the positioning ring to slide on the drill bit, which is convenient for assisting the positioning of the drill bit's rotation and improving the accuracy of the anchor cable casing hole forming processing.

[0028] A push rod 13 is fixed to the top of the sliding frame 5, and the two ends of the sliding frame 5 are respectively slidably sleeved on the two positioning rods 1, and the two positioning rods 1 are slidably sleeved with sliding tubes 6, the elastic band 10 is fixedly connected to the side wall of the sliding tube 6, and a connecting ring 12 is fixedly sleeved on the elastic band 10, and the connecting ring 12 is fixedly connected to the push rod 13. The push rod 13 makes the elastic band 10 and the positioning ring 11 move synchronously through the connecting ring 12. Since the pulling forces of the two elastic bands 10 are the same, the elastic band 10 and the positioning ring 11 assist in positioning the drill bit's rotation. At the same time, when the drill bit is inserted into the anchor cable casing body 7, the side wall of the anchor cable casing body 7 squeezes the positioning ring 11 to slide on the drill bit.

[0029] like Figure 3 and Figure 4 As shown, a connecting plate 2 is fixed to one end of the two positioning rods 1, and a fixing frame 8 is installed at the other end of the two positioning rods 1. Bolts 17 threadedly inserted in the mounting frame 9 are installed on the two fixing frames 8. The two ends of the lead screw 16 with opposite thread directions are respectively threadedly inserted in the two clamping plates 14, and the bottom end of the lead screw 16 is fixedly connected with a knob 15. The top ends of the two lead screws 16 pass through the mounting frame 9 and are fixedly sleeved with gears 18. A toothed belt 19 is meshed between the two gears 18. The knob 15 drives the lead screw 16 to rotate, and the two lead screws 16 rotate synchronously through the gear 18 and the toothed belt 19, and during the rotation, the clamping plates 14 move toward each other to clamp the anchor cable casing body 7.

The two lead screws 16 rotate synchronously through the gear 18 and the toothed belt 19, and during the rotation, the clamping plates 14 move toward each other to clamp the anchor cable casing body 7. Since the two clamping plates 14 move synchronously, the anchor cable casing body 7 is always fixed at the center position of the mounting frame 9.
