Problems solved by technology

[0003] At present, the connection of large-scale space trusses is mostly assembled by screwing, welding, etc., which not only requires large auxiliary hoisting equipment, but also has low assembly efficiency and is difficult to dismantle.
In addition, in some special environments, such as nuclear power plants, underwater, space, etc., it is difficult for personnel to work for a long time, and the current robot is not flexible enough to operate and the control planning is complicated.

Embodiment 1

[0052] Such as figure 1 As shown, this example provides a radial insertion self-locking quick joint suitable for the assembly of space truss structures, mainly including node joints 2 and rod joints 3 . Wherein, the node joint 2 is connected with the truss node 1 to form a node joint assembly, and the bar joint 3 is connected with the truss bar 4 to form a bar joint assembly. The node connecting piece 201 in the node joint 2 and the bar connecting piece 301 in the bar joint have the same shape structure, and have matching concave-convex structures in the same lateral direction to achieve axial connection. When the node joint assembly and the bar joint assembly After close contact along a specific radial direction, when the axes, bumps, and surfaces of the node connector 201 and the rod connector 301 are completely coincident, the locking ring 303 of the rod joint 3 pops up to surround and lock the node connector 201 and the rod connector 301 , to achieve a circumferential loc...

Embodiment 2

[0059] This embodiment provides a case of using the connector of the present invention to realize quick connection of the connector.

[0060] Such as Figure 4 As shown, this example reveals the state of the connector before it is assembled and connected. The truss node 1 is pre-connected with the node joint 2 as a node joint assembly 5, and the truss node 1 is fixed; the bar joint 3 and the truss bar 4 are pre-connected as a bar joint assembly 6. The node joint assembly 5 is parallel to the axis of the rod joint assembly 6, and the tooth grooves of the node connector 201 and the rod connector 301 are complementary to each other. At this time, the rod lock tongue 302 pops up, and its side blocks the locking ring 303 from popping up.

[0061] Such as Figure 5 As shown, this example reveals the joint assembly connection process status. The middle part of the truss member 4 is grasped and pressed down by a human hand or a robot hand, and the rod joint assembly 6 is always kep...

Abstract

The invention relates to a quick connection device, and discloses a radial insertion self-locking quick joint suitable for spatial truss structure assembling. The radial insertion self-locking quick joint includes a joint and a rod piece joint, when assembling connection, a joint connecting piece squeezes a lock tongue of a rod piece to unlock an elastic locking assembly, the elastic locking assembly moves toward the joint connecting piece, and both the joint connecting piece and a rod piece connecting piece are circumferentially surrounded, locked and connected by the elastic locking assembly. The radial insertion self-locking quick joint can be used as a generalized connection device, can be applied to space trusses with various structure types, has the advantages of convenient and quickoperation, high stiffness, high precision, multiple functions and the like, and meet space truss construction needs for the ground, space and other aspects.

Description

technical field [0001] The invention relates to a device in the field of quick connection, in particular to a radial insertion self-locking quick joint suitable for assembly of a space truss structure. The self-locking quick joint only needs to be radially inserted to realize high-rigidity overall connection. The device has a simple structure and high connection rigidity, can be operated by humans or robots, and is suitable for the assembly and construction of various types of space truss structures. Background technique [0002] The construction of large-scale space structures usually adopts truss structures, such as large-scale venue domes, long-span bridges, power telecommunication towers, large-scale space antennas, and large-scale space power stations. Space truss structures have outstanding mass density advantages through space topology optimization. [0003] At present, large-scale space trusses are mostly connected by bolting, welding and other assembly methods, whic...
