Description

Technical Field

[0001] The invention relates to the technical field of tooling fixtures, and in particular to a full-dimensional rotation positioning wire clamp for a rigid suspension bus. Background Art

[0002] The rigid suspended contact network system of rail transit generally suspends the bus above the line through a vertical suspension of a steel structure or a horizontal rotating arm (such as the technology used in the Beijing New Airport Line) and a bus positioning clamp, and clamps the contact wire through the bus.

[0003] The rigidly suspended positioning clamps are divided into elastic clamps and fixed clamps according to whether there are springs to provide elasticity; they are divided into fixed clamps and sliding clamps according to the fixing form of the clamps and the busbars; they are divided into fixed clamps and rotatable clamps according to whether the clamps constrain the busbars. The existing fixed clamps cannot conveniently adjust the height of the conductor by adjusting the positioning clamps. At the same time, the existing clamps do not have the function of 360-degree rotation in the horizontal direction. When the busbar rotates in the horizontal direction, it cannot better cooperate with the rotation of the busbar. When the busbar fluctuates along the track direction, it cannot provide angle adaptation.

[0004] The reasons for the above problems are: the busbar itself has a certain rigidity and strength. When the busbar is arranged, the wire clamp needs to have a horizontal rotation function due to the pull-out value requirement. When there are changes in slope and height, the busbar fluctuates and there is movement along the track direction, as well as construction errors in the vertical direction of the rail surface when the wire clamp is installed, all of which lead to non-axial forces from the busbar to the wire clamp. Therefore, the busbar wire clamp needs to have a full-dimensional rotation function. Summary of the invention

[0005] In view of this, the present invention aims to overcome the defects existing in the above-mentioned prior art and provide a rigid suspension bus full-dimensional rotation positioning clamp with full-dimensional adjustment function.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] A full-dimensional rotation positioning wire clamp for a rigid suspension bus, comprising a bolt pin and a wire clamp assembly for fixing the bus, wherein the extension direction of the contact wire clamped by the bus is set as a first direction; a raised contact is provided at the bottom end of the bolt pin; a socket is provided in the wire clamp assembly, wherein the socket comprises a through swing limit hole and a ball socket, wherein the swing limit hole is a long hole extending along the first direction, and the size of the contact is greater than the width of the swing limit hole;

[0008] The bolt pin is inserted into the swing limit hole, and the contact is inserted into the ball socket. The bolt pin can swing in the swing limit hole. The swing amplitude of the bolt pin along the length direction of the swing limit hole is greater than the swing amplitude along the width direction of the swing limit hole, and the contact can rotate in the ball socket.

[0009] Furthermore, the rigid suspension bus full-dimensional rotation positioning wire clamp also includes a retaining ring, which is arranged on the bolt pin and is separated from the wire clamp assembly, and the width of the retaining ring is greater than the width of the swing limit hole.

[0010] Furthermore, the contact is a cone with a convex side wall; and the socket is a conical hole with a convex side wall.

[0011] Furthermore, the height of the contact is smaller than the depth of the socket.

[0012] Furthermore, the wire clamp assembly includes a wire clamp body and a wire clamp cover fixedly assembled on the side of the wire clamp body, and the wire clamp body and the wire clamp cover are provided with relatively bent L-shaped bent plates on both sides of the bottom.

[0013] Furthermore, a lap joint surface is provided on the top of the wire clamp cover extending toward one side of the wire clamp body, and the lap joint surface is lap jointed on the wire clamp body.

[0014] Furthermore, the rigid suspension busbar full-dimensional rotation positioning clamp further comprises a positioning structure for fixing and assembling the bolt pin on a base, and the positioning structure is arranged on the bolt pin;

[0015] The positioning structure includes a first positioning clamping plate and a second positioning clamping plate. The first positioning clamping plate is connected to the bolt pin by threads. The second positioning clamping plate is provided with a through hole for the bolt pin to pass through. The first positioning clamping plate and the second positioning clamping plate are assembled and fixed by positioning bolts.

[0016] Furthermore, a fastening nut is screwed onto the bolt pin, and the fastening nut tightens the positioning structure.

[0017] Furthermore, it also includes a connecting wire, both ends of which are provided with connecting terminals, one of the connecting terminals is connected and fixed to the wire clamp assembly, and the other of the connecting terminals is fixedly connected to the basic setting, and the positioning wire clamp is electrically connected to the infrastructure through the connecting wire.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The present invention provides a rigid suspension bus full-dimensional rotation positioning wire clamp, wherein the wire clamp assembly is suspended at the bottom end of a bolt pin by plugging a contact with a socket, and the socket is provided with a swing limit hole, wherein the swing limit hole is a long hole, and the bolt pin is inserted into the swing limit hole. Due to the shape of the swing limit hole, the wire clamp assembly provided with the socket can swing greatly along the length direction of the swing limit hole, that is, the line extension direction of the contact line, swing slightly along the width direction of the swing limit hole, and has the function of rotating 360 degrees in the horizontal direction.

[0020] The full-dimensional rotating positioning wire clamp for the rigid suspension bus provided by the present invention has higher flexibility than traditional hinges; compared with ball joints, it can limit the lateral swing amplitude of the wire clamp assembly and the contact line clamped by the bus through the swing limit hole, so that the wire clamp assembly can adapt to the deviation of the bus along the track direction when there are changes in slope and guide height, as well as the construction error in the vertical rail surface direction and deviation from the track direction, and will not deviate too much from the track direction to hinder the operation of rail vehicles.

[0039] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments:

[0040] like Figure 1-Figure 9 As shown, a full-dimensional rotation positioning wire clamp for a rigid suspension bus includes a bolt pin 20 and a wire clamp assembly 30 for fixing the bus, and the extension direction of the contact line clamped by the bus is set to be a first direction; a protruding contact 23 is provided at the bottom end of the bolt pin 20; a socket 33 is opened in the wire clamp assembly 30, and the socket 33 includes a through swing limit hole 331 and a ball socket 332, the swing limit hole 331 is a long hole extending along the first direction, and the size of the contact 23 is larger than the width of the swing limit hole 331; the bolt pin 20 is inserted into the swing limit hole 331, and the contact 23 is inserted into the ball socket 332, the bolt pin 20 can swing in the swing limit hole 331, the swing amplitude of the bolt pin 20 along the length direction of the swing limit hole 331 is larger than the swing amplitude along the width direction of the swing limit hole 331, and the contact 23 can rotate in the ball socket 332.

[0041] The present embodiment provides a rigid suspension bus full-dimensional rotation positioning wire clamp, in which the wire clamp assembly 30 is suspended at the bottom end of the bolt pin 20 by means of the plug-in arrangement of the contact 23 and the socket 33, and the socket 33 is provided with a swing limit hole 331, wherein the swing limit hole 331 is a long hole, and the bolt pin 20 is inserted into the swing limit hole 331. Limited by the shape of the swing limit hole 331, the wire clamp assembly 30 provided with the socket 33 can swing significantly along the length direction of the swing limit hole 331, that is, the line extension direction of the contact line, swing slightly along the width direction of the swing limit hole 331, and has the function of rotating 360 degrees in the horizontal direction.

[0042] The full-dimensional rotating positioning wire clamp for the rigid suspension bus provided by the present invention has higher flexibility than traditional hinges; compared with ball joints, the wire clamp assembly 30 and the lateral swing amplitude of the contact line clamped by the bus can be limited by the swing limit hole 331, so that the wire clamp assembly 30 can adapt to the displacement of the bus along the track direction when there are changes in slope and height, as well as the construction errors in the vertical rail surface direction and deviation from the track direction, and will not deviate too much from the track direction to hinder the operation of rail vehicles. At the same time, the wire clamp assembly 30 can rotate 360 ​​degrees, and can better cooperate with the bus when the direction of the bus changes. Moreover, the positioning wire clamp does not use elastic parts such as springs, is not affected by the fatigue life of elastic parts, has a longer service life, and has a more stable effect.

[0043] In this embodiment, the contact 23 is a cone with a convex side wall, and the ball socket 332 is a conical hole with a convex side wall, so as to facilitate processing and rotation of the contact 23. During assembly, the bolt pin 20 in this embodiment can be inserted into the socket 33 from bottom to top.

[0044] In this embodiment, the height of the contact 23 is less than the depth of the ball socket 332 to prevent the contact 23 from protruding from the bottom surface of the clamp assembly 30 during the swinging process, thereby affecting the positioning of the busbar.

[0045] In this embodiment, the sizes of the contact 23, the ball socket 332 and the swing limit hole 331 can be set as needed. For example, the swing amplitude of the clamp assembly 30 along the track, that is, the line direction of the contact line is 5°, and the swing amplitude perpendicular to the line is 2°.

[0046] The rigid suspension busbar full-dimensional rotation positioning wire clamp provided in this embodiment also includes a retaining ring 22, which is an elastic retaining ring 22 for shaft, and limits the position by an annular groove provided on the outer wall of the bolt pin 20. The retaining ring 22 is separated from the wire clamp assembly 30, and the width of the retaining ring 22 is greater than the width of the swing limit hole 331, and is used to limit the displacement distance of the wire clamp assembly 30 along the axial direction of the bolt pin 20.

[0047] In this embodiment, the wire clamp assembly 30 includes a wire clamp body 31 and a wire clamp cover 32 fixedly assembled on the side of the wire clamp body 31. The wire clamp body 31 and the wire clamp cover 32 are fixedly connected by clamping bolts 34. The wire clamp body 31 and the wire clamp cover 32 are provided with relatively bent L-shaped bent plates on both sides of the bottom. The two L-shaped bent plates form a semi-enclosed structure at the bottom of the wire clamp assembly 30 to improve the stability of the busbar positioning.

[0048] Preferably, a lap surface is provided on the top of the wire clamp cover 32 extending toward one side of the wire clamp body 31, and the lap surface is overlapped in a notch provided on the wire clamp body 31, so that the clamping bolt 34 only bears the clamping force but not the vertical downward shear force.

[0049] The rigid suspension bus full-dimensional rotation positioning clamp provided in this embodiment also includes a positioning structure 10 for fixing the bolt pin 20 to a basic setting, such as a vertical suspension of a steel structure or a horizontal rotation arm, and the positioning structure 10 is arranged on the bolt pin 20.

[0050] Exemplarily, the positioning structure 10 may include a first positioning clamping plate 11 and a second positioning clamping plate 12, an external thread 21 is provided on the upper portion of the bolt pin 20, the first positioning clamping plate 11 is connected to the bolt pin 20 by threads, the second positioning clamping plate 12 is provided with a through hole for the bolt pin 20 to pass through, and the first positioning clamping plate 11 and the second positioning clamping plate 12 are assembled and fixed by positioning bolts 14. Of course, in other embodiments, the second positioning clamping plate 12 may be connected to the bolt pin 20 by threads, and the first positioning clamping plate 11 may be provided with a through hole for the bolt pin 20 to pass through.

[0051] Furthermore, in this embodiment, a fastening nut 13 is screwed onto the bolt pin 20, and the fastening nut 13 presses against the positioning structure 10 to prevent the positioning structure 10 from loosening. More preferably, an elastic gasket may be provided between the fastening nut 13 and the positioning structure 10. Similarly, elastic gaskets may be provided between other bolt-like structures and nut-like structures used in this embodiment, such as the positioning bolt 14, the clamping bolt 34 and the structures connected thereto, as required.

[0052] It is conceivable that in other embodiments, other existing structures can also be used as the positioning structure 10 for fixing the bolt pin 20 to the basic setting.

[0053] Furthermore, the rigid suspension busbar full-dimensional rotation positioning wire clamp provided in this embodiment also includes a connecting wire 40, and both ends of the connecting wire 40 are provided with connecting terminals 41, one connecting terminal 41 is connected and fixed to the wire clamp assembly 30, and the other connecting terminal 41 is fixedly connected to the basic setting such as the vertical suspension or horizontal rotation arm of the steel structure, and the positioning wire clamp is electrically connected to the infrastructure through the connecting wire 40. The structure and method of the electrical connection are prior art and will not be repeated here.

[0054] Note: For the fixed connection methods described in this article, unless otherwise specified, existing fixed connection methods such as threaded connection, welding, and bonding can be used.
