It should be noted that the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed, unless otherwise specifically indicated and defined. The specific meaning of such terms in this patent will be understood by those of ordinary skill in the art as the case may be.
As shown in fig. 1, the lower anchor wire bearing frame of the catenary of the present invention comprises a main frame body 1 erected on a structure; the bottom of the main frame body 1 is provided with a positioning pulley 2 which can slide along the horizontal direction; an auxiliary frame body 3 is also erected below the main frame body 1, a horizontally extending adjusting wrist arm 4 is arranged on the auxiliary frame body 3, and a supporting sleeve 5 is connected to the adjusting wrist arm 4 through a sleeve single lug; a double-ring rod 6 is hinged between the support sleeve 5 and the positioning pulley 2; and the supporting sleeve 5 is provided with a lead fixing tool 7 through a sleeve seat.
In this embodiment, for the contact net at the concrete pier and column, in order to avoid enough insulation distance between the contact net and the structure after the bearing wire is erected, after the main frame body 1 is installed, the position of the bearing wire fixing tool 7 can be changed by adjusting the distance between the bearing wire and the special structure relative to the adjusting cantilever 4 through single lug of the supporting sleeve 5, so as to control sufficient insulation interval between the bearing wire and the special structure. In the position adjustment process of the support sleeve 5, the positioning pulley 2 can horizontally slide along the main frame body 1 so as to keep the bearing capacity of the double-ring rod 6 and the support sleeve 5, and ensure that the bearing strength of the bearing wire is enough.
The installation position and the inclination angle of the support sleeve 5 can be adapted by selecting double ring rods 6 with different lengths according to the specifications of different structures.
As one embodiment, the main frame 1 has a triangular structure formed by a cross beam and an oblique beam, wherein the cross beam is connected to one end of the oblique beam, and the other end is anchored to the structure by an anchor. The sub-frame 3 is an L-shaped steel beam directly anchored to the structure.
In addition, the crossbeam is arranged horizontally, and a supporting beam is erected between the crossbeam and the oblique beam, so that the strength is further improved.
As an implementation mode, the two ends of the double-ring rod 6 are hinged with hinge wheels 6.1 which are respectively connected with the support sleeve 5 and the positioning pulley 2, so that the inclination angle of the double-ring rod 6 can be synchronously changed when the double-ring rod is adjusted along with the support sleeve 5, and when the follow-up bearing wire slightly oscillates, partial stress can be offset through the inclination angle change, and the nonlinear disturbance of the bearing wire is prevented.
As an embodiment, as shown in fig. 2, the cross beam is an i-beam, and a chute matching with the i-beam is formed in the positioning pulley 2.
As an embodiment, as shown in fig. 3, the lead fixing tool 7 includes a U-shaped locking ring 7.1 and a pressing plate 7.2; the end part of the U-shaped locking ring 7.1 can penetrate through the pressing plate 7.2, and a locking groove is formed between the U-shaped locking ring and the pressing plate 7.2; the end of the U-shaped locking ring 7.1 is fixed with the pressing plate 7.2 through bolts. After the bearing wire can penetrate through the locking groove, the U-shaped locking ring 7.1 is locked by the bolt to fix the bearing wire.
In order to ensure that the bearing wire is more stable, the supporting tube 7.3 is preset in the locking groove, and the contact surface of the bearing wire and the locking groove is ensured to be more compact.
As an implementation manner, the adjusting cantilever 4 is further provided with a rod insulator 8, so that the insulation performance is improved.
