Embodiment 1

[0048] Such as figure 1 Shown is a docking device with a clamping mechanism, a docking device with a clamping mechanism, including: a plug-in assembly 1 and a socket 2 respectively connecting two large arms for sealing the net; the socket 2 includes a second base 20 And the female butt joint, the female butt joint includes: a tapered claw with a variable opening size; the tapered claw is rotatably connected to the second base 20, and the side wall of the tapered claw is inclined to the bottom; the receiving part 2 passes through the The second base 20 is fixed on a net sealing arm; the plug-in assembly 1 includes a first base 10 and a male butt joint 12, the first base 10 and the male butt joint 12 are rotatably connected, and the plug-in assembly 1 is fixed by the first base 10 On the other blocking arm. The male butt joint 12 can rotate along the spherical surface of the first base 10, and its rotation has three degrees of freedom, and can be rotated according to the dockin...

Embodiment 2

[0053] Such as Figure 4 As shown, the present invention provides a docking device with a clamping mechanism, including two frame bodies 4 oppositely arranged on both sides, a net sealing arm 5, a driving device 6 fixedly installed on the frame body 4, and embodiment 1 A docking device with a clamping mechanism provided in . Both sides sealing big arm 5 is slidably connected on frame body 4, and sealing big arm 5 is connected with driving device 6, and driving device 6 drives network sealing big arm 5 to slide left and right on frame body 4. The bottom of the net sealing boom 5 is connected with a plurality of hard sealing net holding bars 7, which play the role of protection.

[0054] Such as Figure 5 As shown, the plug-in component 1 and the receiving component 2 are respectively fixedly connected to the network-sealing boom 5 on both sides, and the network-blocking boom 5 slides relatively, so that the plug-in component 1 and the receiving component 2 complete the dockin...

Embodiment 3

[0057] Based on the same inventive concept, the present invention also provides a working method with a clamping mechanism docking device, such as Image 6 shown, including:

[0058] Step 1: When connecting the two net-blocking arms, push the plug-in component 1 fixed on one of the net-blocking arms through the base to the receiving part 2 fixed on the other net-blocking arm;

[0059] Step 2: Turn the male butt joint 12 connected to the first base 10 on the first base 10 of the plug-in assembly 1, and at the same time turn the female butt joint connected to the second base 20 on the second base 20 of the socket 2, Align the male butt joint 12 with the female butt joint;

[0060] Step 3: The insertion rod 120 of the male butt joint 12 enters the position of the horizontal plate 22 of the tapered claw under the guidance of the rounded corner of the tapered claw B15, and continues to push the compression spring B17 to make the tapered claw The horizontal displacement is generat...

Abstract

The invention provides a butt-joint device with a clamping mechanism. The butt-joint device comprises a plug-in assembly and a bearing piece which are connected with two sealing big arms respectively; the bearing piece comprises a second base and a concave butt joint head, and the concave butt joint head comprises a conical clamping jaw with a variable opening size; the conical clamping jaw is rotationally connected with the second base, and the side wall of the conical clamping jaw inclines towards the bottom; the bearing piece is fixed on one sealing big arm through the second base; and the plug-in assembly comprises a first base and a convex butt joint, the first base is rotationally connected with the convex butt joint, and the plug-in assembly is fixed to the other large sealing big arm through the first base. The joints at the two sides are hinged to the bases and have three rotational degrees of freedom, the butt-joint posture can be adjusted according to the contact condition of the butt-joint joints, adjustment of butt-joint big arms in the butt-joint operation is reduced, the fault tolerance of the butt-joint device is improved, and the posture requirement of the sealing big arm in the butt-joint process is lowered.

Description

technical field [0001] The invention relates to power transmission line construction equipment and construction technology, in particular to a docking device with a clamping mechanism. Background technique [0002] With the rapid development of UHV construction, during the construction of new power lines, there are more and more cases where cross-over construction is required for existing power lines, high-speed railways, and expressways. As the main construction equipment and safety measures for spanning construction, the spanning frame can ensure the safe and efficient development of the project. The existing spanning frames all need to be assembled and docked at high altitude on site. The existing docking method has a large amount of high-altitude operations, poor safety, high docking difficulty, and long construction time. It is difficult to meet the window period requirements for crossing high-speed rail and lines. Contents of the invention [0003] In order to overc...
