Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a tie rod device for a space cable. Background Technology

[0002] With the development of suspension bridge construction technology, spatial cable suspension bridges have been increasingly widely used. A spatial cable suspension bridge consists of a main cable and suspenders forming a three-dimensional cable system. The main cable's alignment is a spatial structure, and during system transitions, the main cable undergoes vertical, horizontal, and longitudinal displacement, resulting in three-dimensional displacement of the cable clamps. While having minimal impact on vertical load-bearing capacity, the lateral load-bearing capacity of the spatial cable system is significantly improved, thereby greatly enhancing the overall lateral stiffness and torsional stiffness of the bridge, and improving its wind resistance and stability.

[0003] In the prior art, such as the transverse tensioning device of a spatial cable surface structure cable system with patent number CN205399213U, it includes multiple pairs of main cable tensioning seats fixed on two main cables respectively. Each pair of main cable tensioning seats includes two main cable tensioning seats installed on the two main cables in the transverse direction. Each main cable tensioning seat includes a seat body. The upper and lower parts of the seat body are symmetrically opened with horizontally arranged cable holes. A steel strand bundle is passed through the cable holes of each pair of main cable tensioning seats. An anchor is connected to the outer wall of the main cable tensioning seat at both ends of each steel strand bundle. The anchor fixes the steel strand bundle to the main cable tensioning seat. An upper horizontal plate and a lower horizontal plate are respectively protruding outward from the middle of the outer wall of the seat body. The upper horizontal plate and the lower horizontal plate are coaxially opened with pin holes arranged in the vertical direction. The pin holes are used to connect the tensioning seat to the cable clamp plate on the main cable so that the tensioning seat acts on the main cable. The main cable alignment using this structure is close to that of a completed bridge.

[0004] However, in the existing technology, the lateral tensioning device is directly connected to the main cable clamp, and the clamp is used as the bearing point of the tensioning force of the main cable. During the lateral tensioning construction, the rotational freedom of the main cable is constrained. When the lateral tensioning is released in the completed bridge state, the constrained rotational torque may affect the bridge alignment, which poses a problem of affecting the bridge alignment. Utility Model Content

[0005] This application provides a tie rod device for space cables, which can solve the problem in the prior art where the lateral tie rod device is directly connected to the main cable clamp and uses the clamp as the bearing point of the main cable tie force. During the lateral tie rod construction, the rotational freedom of the main cable is constrained. When the lateral tie rod is released in the completed bridge state, the constrained rotational torque may affect the bridge alignment, which is a problem that affects the bridge alignment.

[0006] In a first aspect, embodiments of this application provide a pull-up device for a space cable, comprising: Two temporary cable clamps are respectively installed on adjacent main cables. Each temporary cable clamp includes a connecting cable clamp and a rotating sleeve. The rotating sleeve is used to fix the main cable and is rotatably installed inside the connecting cable clamp.

[0009] In one embodiment, each of the semicircular arc plates is provided with a connecting plate at its arc-shaped end. The connecting plates on the two semicircular arc plates are arranged correspondingly, and the two opposing connecting plates are connected by a first connecting bolt. The connecting plate is connected to a first stiffening plate on the same semicircular arc plate.

[0010] In one embodiment, the connecting plate is provided with a plurality of second stiffening plates at intervals along the length of the plate. The second stiffening plates are connected to the semi-circular arc plate and are arranged to intersect with the first stiffening plates.

[0011] In one embodiment, the connecting base is provided with cable holes spaced apart along the height direction, and the pull mechanism includes two pull units corresponding to the cable holes, the pull unit comprising: A steel strand bundle passes through corresponding cable holes on the two connecting bases; A jack, which is connected to the steel strand bundle and to one of the connecting bases; An anchor is connected to the end of the steel strand bundle away from the jack and fixed to another connecting base.

[0013] In one embodiment, a connecting plate is provided on the upper side of the first stiffening plate on the semi-circular arc plate near the inner side, the connecting plate connecting all the first stiffening plates on the semi-circular arc plate near the inner side.

[0014] In one embodiment, the rotating sleeve includes: Two semi-circular steel plates are arranged opposite to each other. A connecting assembly that connects the two semi-circular steel plates.

[0015] In one embodiment, both ends of the rotating sleeve extend out of the mounting cavity, and the connecting components are provided on the outer sides of both ends of the rotating sleeve. The connecting cable clamp in the same temporary cable clamp is located between two connecting components arranged along the axial direction.

[0016] The beneficial effects of the technical solutions provided in this application include: When using this tensioning device for space cables, two temporary cable clamps are respectively installed on adjacent main cables. Each temporary cable clamp includes a connecting cable clamp and a rotating sleeve. The rotating sleeve is fixed to the main cable and rotatably mounted within the connecting cable clamp. The tensioning mechanism is connected to the two connecting cable clamps to bring them closer together. Because the rotating sleeve is rotatably mounted within the connecting cable clamp, the main cable can undergo unconstrained lateral displacement, achieving the desired effect of replacing the arc with a multi-segment line. The main cable alignment closely approximates the alignment of the completed bridge. This solves the problem in existing technologies where the lateral tensioning device is directly connected to the main cable clamps, using the clamps as the bearing point of the tensioning force on the main cable. During lateral tensioning construction, the rotational freedom of the main cable is constrained. When the lateral tensioning is released in the completed bridge state, the constrained rotational torque may affect the bridge alignment, posing a problem affecting the completed bridge alignment.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0026] This application provides a tie rod device for a space cable, which solves the problem in the prior art where the lateral tie rod device is directly connected to the main cable clamp and uses the clamp as the bearing point of the main cable tie force. During the lateral tie rod construction, the rotational freedom of the main cable is constrained. When the lateral tie rod is released in the completed bridge state, the constrained rotational torque may affect the bridge alignment, thus affecting the bridge alignment.

[0027] like Figure 1 and Figure 2 As shown, this application provides a pull-up device for a space cable, comprising: Two temporary cable clamps 1 are respectively installed on adjacent main cables 2. Each temporary cable clamp 1 includes a connecting cable clamp 3 and a rotating sleeve 4. The rotating sleeve 4 is used to fix on the main cable 2 and is rotatably installed in the connecting cable clamp 3. The pull mechanism 5 is connected to two connecting cable clamps 3 and is used to bring the two connecting cable clamps 3 closer to each other.

[0028] When using this tensioning device for space cables, two temporary cable clamps 1 are respectively installed on adjacent main cables 2. Each temporary cable clamp 1 includes a connecting cable clamp 3 and a rotating sleeve 4. The rotating sleeve 4 is fixed to the main cable 2 and rotatably installed within the connecting cable clamp 3. The tensioning mechanism 5 is connected to the two connecting cable clamps 3 to bring them closer together. Because the rotating sleeve 4 is rotatably installed within the connecting cable clamp 3, the main cable 2 can undergo unconstrained lateral displacement, achieving the desired effect of replacing the arc with a multi-segment line. The alignment of the main cable 2 is close to the alignment of the completed bridge state. This solves the problem in the prior art where the lateral tensioning device is directly connected to the main cable clamps, using the cable clamps as the bearing point of the tensioning force of the main cable. During lateral tensioning construction, the rotational freedom of the main cable is constrained. When the lateral tensioning is released in the completed bridge state, the constrained rotational torque may affect the alignment of the completed bridge, posing a problem that affects the alignment of the completed bridge.

[0029] In this example, the inner side of the rotating sleeve 4 is provided with an asbestos mesh with a thickness of 1mm to ensure that there is no relative rotation between the rotating sleeve 4 and the main cable 2, and to protect the outer layer of the main cable 2 from damage. The outer side of the rotating sleeve 4 is polished smooth and coated with grease to ensure the rotation effect between the rotating sleeve 4 and the connecting cable clamp 3.
