Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a quick-clamp fixture for a pipeline detector transceiver device. Background Technology

[0002] Quick-clamp grippers for pipeline inspection machine transceivers are widely used due to their ease of operation. However, existing quick-clamp grippers still have the following significant problems in achieving the "quick installation" function:

[0003] Insufficient installation efficiency:

[0004] Traditional pipeline inspection machines use quick-clamping devices (e.g., bolt-locking clamps) that require multiple rotations of the handle or the use of auxiliary tools (e.g., wrenches) to complete the clamping process. This is cumbersome and time-consuming, especially in pipeline inspection operations where frequent assembly and disassembly are required.

[0005] The contradiction between clamping stability and adjustment flexibility:

[0006] Some quick-clamping fixtures simplify operation through spring or slide rail designs, but the clamping force is difficult to adjust precisely: too little clamping force can cause the transceiver to loosen, while too much clamping force may damage the surface of the transceiver. In addition, existing fixtures have poor adaptability to irregularly shaped workpieces (e.g., curved surfaces, thin-walled parts), requiring the addition of additional adapter shims, which further reduces installation efficiency.

[0007] Structural complexity and cost issues:

[0008] To enable rapid clamping and installation of the transceiver, some pipeline inspection machines use multi-link mechanisms or pneumatic components for their quick-clamping devices, resulting in complex structures, bulky size, and high manufacturing costs, making it difficult to promote their use in harsh outdoor environments.

[0009] In view of the above, it is necessary to study a quick-clamping fixture for the receiving and dispatching device of a pipeline inspection machine to solve the above problems. Utility Model Content

[0013] Furthermore, the spring is installed in a pre-compressed state in the spring groove; the initial preload is changed by adjusting the fixing nut.

[0014] The hand-tightening part above the hand-tightening screw passes through the positioning hole of the tray, and the locking contact surface of the hand-tightening screw forms a surface contact with the upper surface of the tray to achieve rigid locking.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below.

[0029] Example 1

[0030] like Figures 1-3 As shown in the figure, this utility model embodiment provides a quick-clamp fixture for a pipeline detector transceiver device. The quick-clamp fixture adopts a modular design and is mainly composed of a fixed base 1, a hand-tightening screw 2, a fixing nut 3, a spring 4, and a tray 5.

[0031] The fixed base 1, serving as the basic load-bearing component on the receiver / discharge tube, is made of high-strength material and features standardized mounting holes for bolt fixation to the workbench or other equipment base. The tray 5, acting as the floating component of the cable puller base, is designed for lightweight operation. The locking mechanism employs a two-stage progressive locking design. Initially, the spring 4 is pre-compressed and installed in the spring groove 6, providing initial preload. Adjusting the fixing nut 3 changes the initial preload. The threaded portion below the hand-tightening screw 2 passes through the center of the spring 4 and the bottom through-hole of the spring groove 6, forming a threaded connection with the fixing nut 3. The hand-tightening portion above the hand-tightening screw 2 passes through the tray positioning hole, and rotating the hand-tightening position 8 drives the threaded pair to generate axial displacement. When rotated by a certain angle, the locking contact surface of the hand-tightening screw 2 forms surface contact with the upper surface of the tray 5, achieving rigid locking.

[0032] The locking mechanism is a mechanical component used to fix or connect, preventing accidental movement or separation. Its number is selected according to the needs of the actual application, and this embodiment of the invention does not limit this.

[0033] The specific implementation steps are as follows:

[0034] (1) Fix the fixing base 1 to the receiver tube;

[0035] (2) Install spring 4 in sequence, insert hand screw 2, and screw in fixing nut 3 to the initial pre-tightened state;

[0036] (3) Place the tray 5 fixed below the cable puller so that its positioning groove 7 is aligned with the hand screw 2;

[0037] (4) Rotate the hand knob position 8 clockwise to the locking position to achieve elastic locking and complete the final fixation.

[0038] According to actual application requirements, the following configuration adjustments can be made in Example 2:

[0039] 1) Under heavy load conditions, multiple sets of distributed locking mechanisms can be used, and the diameter of a single spring wire can be appropriately increased;

[0040] 2) The hand-tightening screw 2 can be replaced with a pneumatic clamp to achieve automated tightening and loosening control.

[0041] The mounting base 1, serving as the basic support structure, is located at the bottom layer and is fixed to the top of the receiver / receiver tube by bolts. The spring 4 is pre-compressed and installed in the spring groove of the mounting base 1, providing preload. The hand-tightening screw 2 runs through the entire structure, passing through the positioning hole of the tray 5 above, and its contact surface forms a rigid lock with the upper surface of the tray 5. The central threaded rod passes through the center of the spring and the through hole at the bottom of the spring groove. Below, it forms a threaded pair with the fixing nut, and the spring preload is adjusted by rotating the fixing nut. The tray 5, as a floating component, is located above the mounting base 1. When fixed, it is pressed tightly by the locking contact surface of the hand-tightening screw 2, achieving rigid fixation.

[0042] The above-described embodiments achieve a balance between rapid installation and precise positioning through modular design, featuring a compact structure, convenient operation, and strong adaptability. Those skilled in the art can make appropriate adjustments to the specific embodiments according to actual needs without departing from the principles of this invention.

[0043] In summary, this utility model embodiment provides a quick-clamping device for a pipeline detector receiving and dispatching device. This quick-clamping device is highly efficient and simple in structure, improving the stability, reliability, and safety of the inspection robot to a certain extent. Especially in production testing assembly line scenarios, this quick-clamping device can achieve higher efficiency and a more convenient fastening method.
