Detailed Description

The multidimensional positioning wire clamp of the rigid overhead line system of the urban rail transit is mainly applied to a suspension structure of the rigid suspension system of the urban rail transit, and as shown in figures 1-2, a structural perspective view and a front view of a first embodiment of the positioning wire clamp sequentially comprise a rotating main shaft 1, a swing bearing 2, a connecting base 3 and an angular supporting plate 4 from top to bottom. Similar to a conventional positioning wire clamp, the top of the rotating main shaft 1 of the utility model can be tightly connected with an insulator, and the connecting base 3 and the angular supporting plate 4 are used for clamping a busbar.

Referring to fig. 3, the rotating spindle 1 of the present embodiment is divided into an upper spindle 11, a middle spindle 13 and a lower spindle 12 from top to bottom; as shown, the diameters of the three parts increase from top to bottom in sequence. As shown in fig. 4, the bottom surface of the rocking bearing 2 is provided with a second through hole for inserting the rotating main shaft 1, and the second through hole extends to the top surface of the rocking bearing 2 to form a third through hole 22 for the upper main shaft 11 of the rotating main shaft to pass through.

In order to make the rotatable connection between the bottom of the rotating spindle 1 and the oscillating bearing 2 when mounted, the diameter of the third through hole 22 is smaller than the diameter of the lower spindle 12 in this embodiment, the diameter of the second through hole on the bottom surface of the oscillating bearing 2 is larger than or equal to the diameter of the lower spindle 12, and the diameter of the middle spindle 13 is equal to or smaller than the diameter of the third through hole 22. Meanwhile, the outer side surface of the upper main shaft 11 is further provided with threads, that is, the upper main shaft 11 can be a screw rod structure, and a nut 71 is sleeved outside the screw rod, and the outer diameter of the nut 71 is larger than the diameter of the third through hole 22, so as to prevent the middle main shaft 13 from passing through the third through hole 22. Optionally, a fourth through hole 15 is further formed on the nut 71, the fourth through hole 15 extends through the upper spindle 11, and the locking pin 6 is inserted into the fourth through hole 15, so as to further enhance the stability of the whole structure.

Thus, when the installation is performed, the upper main shaft 11 of the rotating main shaft 1 can be inserted through the second through hole on the bottom surface of the swing bearing 2 and can be penetrated through the third through hole 22 on the top surface of the swing bearing 2, and the middle main shaft 13 and the lower main shaft 12 of the rotating main shaft 1 can be sleeved inside the swing bearing 2. So that a relatively stable clamping sleeve connecting structure can be formed between the rotating main shaft 1 and the interior of the swing bearing 2, meanwhile, the rotating main shaft 1 can freely rotate around the axis of the rotating main shaft relative to the swing bearing 2, a certain wire clamp rotating angle can be set according to design requirements during installation, and then the rotating main shaft 1 is fixed by utilizing a limiting component 7 (the structure of the limiting component will be explained in detail below) sleeved outside the upper main shaft, so that the system arrangement and installation requirements can be met to a great extent.

As shown in fig. 1-2 and 5, the top surface of the coupling base 3 has two walls 31 protruding upward and spaced from each other, and each of the walls 31 has a first through hole 32. As shown in the figure, the oscillating bearing 2 is arranged between two walls 31 of the coupling base 3, and a first through hole 32 extends through the oscillating bearing 2, and the oscillating bearing 2 is hingedly connected to the coupling base 3 by the pin 21 penetrating through the first through hole 32. The swing bearing 2 can rotate relative to the connecting base 3 around the axis direction of the pin shaft 21, so that the wire clamp has the function of turning along the line direction, the local gradient deviation of front and rear positioning points is adjusted by the wire clamp, and the integral height guide smoothness of the rigid contact net is ensured. At the same time, it will be understood by those skilled in the art that the oscillating bearing 2 can be arranged outside the two walls 31 to form an articulated connection with the coupling base 3, in addition to being arranged between the two walls 31 to articulate with the coupling base 3 according to the present embodiment.

Here, two pins 21 can be used, one inserted into the first through hole 32 on the left side (shown in fig. 5) of the coupling base 3 and the other inserted into the first through hole 32 on the right side, so that the pins 21 can avoid the insertion region of the rotary spindle 1 in the oscillating bearing 2. It should be understood that the insertion region of the pin 21 may also be selected to be inserted into the lower region where the rotating spindle 1 (the lower spindle 12) is located, and directly avoid the rotating spindle, and this insertion may be implemented by using one pin.

In the present embodiment, as shown in fig. 4, two fifth through holes 23 extending perpendicularly to the pin shafts 21 are provided on the outer side surface of the swing bearing 2, and the fifth through holes 23 pass through the two pin shafts 21. As also shown in fig. 2, two locking pins 6 are inserted into the fifth through holes 23, respectively, to lock the positions of the two pins 21 in the swing bearing 2, thereby enhancing the stability of the overall structure.

In addition, the design of a hollow structure is added to the connecting base 3 in the embodiment. When the rocking bearing 2 rotates about the axis of the pin 21, the bottom of the rocking bearing 2 comes into contact with the area of the coupling base 3 between the walls 31. This embodiment is provided with an opening 33 in the area of the coupling base 3, which is designed such that when the swing bearing 2 rotates about the axis of the pin shaft 21, the bottom of the swing bearing 2 will partially rotate into the opening 33 without direct collision with the coupling base 3, thereby increasing the rotatable angle of the swing bearing 2 when swinging about the pin shaft 21. As shown in fig. 5, the openings 33 in this embodiment are designed as 2 through holes in a rectangular shape.

As shown in fig. 2, the angle support plate 4 comprises a vertical plate and a horizontal plate connected in an L shape, and both ends of the coupling base 3 are fixedly connected with the horizontal plate of the angle support plate 4 by fasteners 42 (bolts with inverted nuts as shown in the figure). Compared with the conventional angle supporting plate, as shown in fig. 6, the embodiment adds a groove 41 for matching and clamping with the end of the connecting base 3 at the upper end of each vertical plate of the angle supporting plate 4; that is, as shown in fig. 1-2, the end of the connecting base 3 can be just inserted into the groove 41, so that a snap connection is formed between the connecting base 3 and the angle support plate 4 to enhance the connection stability between the two and the load-bearing performance of the whole cable clamp.

As shown in fig. 1-2, the positioning line of the present embodiment is further provided with 2 conductive sliders 5 sandwiched between the connection base 3 and the angle support plate 4, and the conductive sliders 5 are also fixedly connected to the connection base 3 and the angle support plate 4 by fasteners 42. As shown in fig. 7, in this embodiment, a U-shaped slot 51 for clamping the bus bar is formed on one side of the conductive slider 5, so as to allow the bus bar to freely slide relative to the wire clip when the bus bar expands or contracts due to temperature change; and the conductive sliding block can be made of conductive plastic materials, so that the conductive sliding block has high-quality wear resistance, good lubricity and good conductivity.

In addition, in order to increase the rotation or sliding performance and improve the service life of each component, a gasket may be interposed between contact surfaces of the components where mutual friction occurs, such as: a flat washer is provided between the contact surface of the lower main shaft 12 and the rocking bearing 2. Meanwhile, a check washer can be arranged between the fastener 42 for fixing the angular supporting plate 4 and the connecting base 3 and the contact surface of the angular supporting plate 4 or the connecting base 3, so as to prevent the loosening of the bolt fastener and increase the connection stability of all parts. For another example, a copper bearing sleeve is arranged at the joint of the pin shaft 21 and the oscillating bearing 2, so that the sliding performance in the overturning process is improved, and the mechanical abrasion of the bearing sleeve is reduced.

As shown in fig. 9, a perspective view of a second embodiment of the present invention is different from the first embodiment in that the coupling base 3 is slightly different in structure. Referring to fig. 8, in particular, the outer bottom portions of the two side walls 31 of the connecting base 3 in the second embodiment are respectively provided with a rectangular block 34 extending toward each side fastener 42, so that the fasteners 42 are clamped between the rectangular blocks 34 and the vertical plates of the angle support plate 4, and the functions of positioning and stopping the fasteners are achieved, and the fasteners can be further prevented from loosening during the operation of the system.

Meanwhile, as shown in fig. 9, the lower spindle of the rotating spindle is sleeved in the swing bearing 2, and the upper spindle 11 exposed outside the swing bearing 2 is sleeved with a limiting component 7 for limiting the rotation of the rotating spindle 1. In this embodiment, the position-limiting assembly 7 is composed of a hexagonal nut 71 and a position-limiting clamp 72, and as in the first embodiment, a thread is provided on the outer side surface of the upper spindle 11, and the nut 71 needs to be sleeved on the thread.

Referring to fig. 11, the limiting clamp 72 is U-shaped and clamped on both sides of the swing bearing 2, and the middle portion thereof is provided with a hexagonal hole 73 matching with the outer contour of the hexagon nut 71, so that the limiting clamp can be sleeved outside the hexagon nut 71, thereby limiting the rotation of the rotating main shaft 1 relative to the swing bearing 2 after installation and preventing the bus bar from being stuck inside the positioning clamp during the expansion process. Preferably, the edge of the upper surface of the rocking bearing 2 in this embodiment also has a chamfered configuration designed for clamping mounting of the mating limit clip 72 (see fig. 9).

Fig. 10 is a schematic perspective view of a third embodiment of the present invention, which is different from the second embodiment mainly in that the structure of the position-limiting component 7 is slightly different. Referring to fig. 12, in the present embodiment, the limiting assembly 7 includes a star-shaped nut 71 and a limiting clip 72 having a star-shaped hole 73, so that the rotating spindle 1 can be rotated to any state when being installed, and the limiting clip 72 is sleeved on the upper spindle 11 to limit the rotating spindle 1. It can be understood that, since the star-shaped hole in the position-limiting clamp has more sides and angles, the applicable installation angle range of the star-shaped hole position-limiting clamp is wider than that of the position-limiting clamp having the hexagonal hole in the second embodiment.

From the foregoing, the utility model is mainly applied to rigid suspension systems for urban rail transit, and compared with the cable clamp applied to rigid suspension systems with large load bearing such as railways, the length of the connecting base in the positioning cable clamp can be properly reduced, specifically, the ratio of the length of the connecting base to the length of the swing bearing is only between 1 and 2. In the four embodiments shown in the figures, the length of the coupling base 3 and the angular support plate 4 in the direction of the line is only slightly greater than that of the oscillating bearing 2.
