Description
Technical Field
[0001] This application relates to the field of pipeline detection auxiliary equipment technology, and in particular to an auxiliary device for underground pipeline detection. Background Technology
[0002] A related technology (announcement number: CN218261880U) discloses an underground pipeline detection auxiliary device, including a frame. Fixed rods are fixed to both sides of the inner wall of the frame. Limit frames are fixed to the ends of the fixed rods. Bolts are threaded onto both sides of the limit frames. A knob is fixed to one end of each bolt, and a connecting plate is rotatably connected to the other end. Several springs are fixed to the surface of the connecting plate. Limit plates are fixed to the ends of the springs. A through groove is opened on the side of the limit plate, and a roller is rotatably installed inside the through groove.
[0003] In the process of implementing the technical solution disclosed herein, at least the following problems were found in the related technologies:
[0004] The rollers of this underground pipeline detection auxiliary equipment can limit the movement of the wire rope, thereby improving its stability during lifting and preventing the manhole cover from swinging and falling, which could affect the smooth operation of the detection personnel. However, during the lifting process, the rollers can only limit the portion of the wire rope above them, while the portion below the rollers will still swing, making it difficult to avoid the risk of it falling off.
[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0016] Optionally, it further includes: limiting blocks, installed on the top wall of the truss frame, and located at both ends of the guide rail.
[0017] The auxiliary device for underground pipeline detection provided in this disclosure can achieve the following technical effects:
[0018] This disclosure provides an auxiliary device for underground pipeline detection, comprising a U-shaped frame, guide rails, sliders, winches, manhole cover hooks, mounting blocks, pressing blocks, and screws. The U-shaped frame rests against the ground, supporting the entire device. Guide rails are installed along the length of the U-shaped frame on its top wall and inside the frame, supporting the slidable sliders. The sliders are slidably mounted on the guide rails, located on both sides of the guide rails along their length; the guide rails and the sliders together provide guidance and support. Winches are installed on both sides of the sliders for lifting. Manhole cover hooks are connected to the ropes of the winches on both sides, rising or falling under the influence of the winch ropes. Mounting blocks are installed on the rods of the manhole cover hooks on both sides, away from the hooks, supporting the relevant components of the installation device. The pressing blocks are slidably fitted onto the rods of the manhole cover hooks on both sides, and are positioned close to the hooks on both sides, both for abutting against the manhole cover. Screws are threadedly connected to the mounting blocks on both sides, and are rotatably connected to the pressing blocks on both sides. The lines of the screws on both sides are parallel to the lines of the rods of the manhole cover hooks on both sides, both for converting rotational motion into linear motion. The sliders on both sides are controllably slidable relative to the guide rails to change the position of the winches on both sides.
[0019] In use, the distance between the winches on both sides can be adjusted by the guide rail and the sliding blocks on both sides, ultimately changing the distance between the manhole cover hooks on both sides. This makes it suitable for lifting manhole covers of different sizes with double lifting points. Then, controlling the winches on both sides to release the ropes allows the manhole cover hooks on both sides to be hooked into the two lifting points of the manhole cover. Then, turning the screws on both sides, through the interaction between the threads and the guiding support of the hooks, the pressing blocks on both sides can press the manhole cover firmly. This ensures that even if the ropes of the winches swing during lifting, the manhole cover will not fall off the hooks. Similarly, when lifting a manhole cover with a single lifting point, controlling one winch and turning one screw on one side completes the lifting operation and prevents the manhole cover from falling off.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0037] Combination Figures 1 to 5As shown, this embodiment of the present disclosure provides an auxiliary device for underground pipeline detection, including a U-shaped frame 1, a guide rail 2, a slider 3, a winch 4, a manhole cover hook 5, a mounting block 6, a pressing block 7, and a screw 8. The U-shaped frame 1 is used to abut against the ground, thereby supporting the entire device. The guide rail 2 is installed along the length of the U-shaped frame 1 on the top wall of the U-shaped frame 1 and located on the inner side of the U-shaped frame 1, used to support the slidable slider 3. The slider 3 is slidably installed on the guide rail 2, located on both sides of the guide rail 2 along its length, and the guide rail 2 and the two side sliders 3 together provide guidance and support. The winch 4 is installed on both side sliders 3 and is used for lifting. The manhole cover hook 5 is connected to the ropes of the two side winches 4, and rises or falls under the drive of the ropes of the two side winches 4. The mounting block 6 is installed on the rod of the two side manhole cover hooks 5, and is located away from the hook of the two side manhole cover hooks 5, used to support the relevant components of the installation device. The pressing blocks 7 are slidably fitted onto the rods of the manhole cover hooks 5 on both sides, and are close to the hooks of the manhole cover hooks 5 on both sides, both for abutting against the manhole cover. The screws 8 are threadedly connected to the mounting blocks 6 on both sides, and under external force, the screws 8 on both sides can rotate relative to the mounting blocks 6 on both sides. The screws 8 are rotatably connected to the pressing blocks 7 on both sides, so that when the screws 8 move the pressing blocks 7 on both sides, the pressing blocks 7 on both sides will not rotate with the screws 8. The straight lines of the screws 8 on both sides are parallel to the straight lines of the rods of the manhole cover hooks 5 on both sides, so as to convert rotational motion into linear motion. The sliders 3 on both sides are controlled to slide relative to the guide rails 2 to change the position of the winches 4 on both sides.
[0038] This embodiment of the invention provides an auxiliary device for underground pipeline detection. With the guiding support of the guide rail 2 and the two side sliders 3, the distance between the two winches 4 can be adjusted, ultimately changing the distance between the two manhole cover hooks 5, thus making it suitable for lifting manhole covers of different sizes with double lifting points. Then, controlling the two winches 4 to release the ropes allows the two manhole cover hooks 5 to be hooked into the two lifting points of the manhole cover. Then, turning the two screws 8 causes the two pressing blocks 7 to press the manhole cover firmly through the interaction between the threads and the guiding support of the rods of the manhole cover hooks 5. This ensures that even if the ropes of the two winches 4 swing during lifting, the manhole cover will not fall off the two manhole cover hooks 5. Similarly, when lifting a manhole cover with a single lifting point, controlling one winch 4 and turning one screw 8 completes the lifting operation and prevents the manhole cover from falling off.
[0039] Optionally, combined Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, it also includes mounting plates 9, motors 10, gears 11, and racks 12. Mounting plates 9 are respectively mounted on the two winches 4 on both sides, serving to support the motors 10. Motors 10 are respectively mounted on the mounting plates 9 on both sides, providing driving force. Gears 11 are respectively mounted on the rotating ends of the two motors 10, rotating under the drive of the two motors 10. Racks 12 are mounted along the length of the frame 1 on the top wall of the frame 1, meshing with the gears 11 on both sides, together converting rotational motion into linear motion.
[0040] In this embodiment, the motors 10 on both sides are controlled to operate. Under the guiding and supporting action of the guide rail 2 and the sliders 3 on both sides, and the meshing action of the rack 12 and the gears 11 on both sides, the mounting plates 9 on both sides can drive the winches 4 on both sides to move along the length direction of the U-shaped frame 1. This allows for adjustment of the positions of the winches 4 on both sides, ultimately changing the positions of the manhole cover hooks 5 on both sides. When lifting a manhole cover with two lifting points, the winches 4 on both sides can be adjusted above the two lifting points respectively, making it easier to hook the manhole cover hooks 5 into the two lifting points. When lifting a manhole cover with a single lifting point, one winch 4 can be adjusted above the lifting point, making it easier to hook a single hook into the lifting point. Therefore, it is convenient to lift manhole covers with both double and single lifting points.
