Description

Technical Field

[0001] The utility model relates to a cable clamp for a suspension bridge, in particular to a cable clamp for a space cable suspension bridge. Background Art

[0002] A suspension bridge is supported and turned by two parallel or nearly parallel main cables on the main tower to bear the dynamic and static loads of the bridge. However, when the main cable anchorage space is limited, there are other technical requirements for bridge stiffness, and the overall landscape design requirements of the bridge type are encountered in the construction of the suspension bridge, the main cable that bears the load along the length direction of the suspension bridge needs to be turned in the vertical direction (i.e. the height direction of the suspension bridge) with a catenary line, and it is also necessary to make a certain amount of arc-shaped offset and turn in the horizontal direction (i.e. the width direction of the suspension bridge). This will make the two main cables supported and turned by the main tower non-parallel, but each main cable on the suspension bridge is arranged in three dimensions: length, height, and width. This type of suspension bridge is what the industry usually calls a space cable system suspension bridge.

[0003] The cable clamp is a key load-bearing component connecting the main cable and the sling of a suspension bridge. Based on the particularity of the structure of the above-mentioned space cable suspension bridge, after the cable clamp is fixed in place on the main cable of the space cable suspension bridge, the sling connected to the cable clamp forms a certain angle with the vertical plane (i.e., the plumb line), and the angle varies depending on the different arrangement positions of the cable clamp on the main cable. Therefore, when the cable clamp is fixed on the main cable of the space cable suspension bridge, it should be referenced to the plumb line to set the angle to locate the sling connection position.

[0004] The cable clamps used in current space cable suspension bridges do not have installation positioning structures. During installation, they are positioned using the following technical means (see Figure 1 shown):

[0005] A marking line 8 is carved on the end face of the cable clamp, which is the axial center line of the sling connected to the cable clamp;

[0006] During on-site installation, the construction personnel use the plumb line 4 in the aligned state as a reference to measure the angle β between the marking line 8 and the plumb line 4 to ensure that the angle β meets the technical requirements of the designed angle.

[0007] The main technical problems existing in the above technical means are as follows:

[0008] 1. The marking line at the end of the cable clamp is easy to be removed, which is especially obvious during the movement and wear of the cable clamp and the erosion during long-term construction;

[0009] 2. The angle measurement between the marking line at the end of the cable clamp and the plumb line requires the use of a specific angle measuring tool, and the angle measurement process is cumbersome. Utility Model Content

[0010] The technical purpose of the utility model is to provide a cable clamp for a space cable suspension bridge with a stable structure and convenient operation during installation and construction in view of the particularity of the above-mentioned space cable suspension bridge structure and the deficiencies of the prior art.

[0011] The technical purpose of the utility model is achieved through the following technical solutions: A cable clamp for a space cable suspension bridge comprises a cable clamp body, wherein the cable clamp body has a structure for connecting a sling;

[0012] The cable clamp body is connected with a level gauge;

[0013] When the cable clamp body is fixed to the main cable setting position of the spatial cable suspension bridge, the plumb line in the alignment state passes through the centering position of the level on the cable clamp body, and the plumb line in the alignment state and the axial center of the suspension cable connected to the cable clamp body form a designed angle.

[0014] The above technical measures add a level meter that matches the designed angle to the cable clamp used in the space cable suspension bridge, so that during the installation and construction of the cable clamp, the level meter carried by the cable clamp is centered to form a specific design angle for installation. Compared with the angle measurement technology, the installation and construction operation has the technical characteristics of being intuitive, convenient and efficient. In addition, the additional structure of the level meter on the cable clamp makes the level meter a part of the cable clamp structure, which can form a specific protection during the movement of the cable clamp, and can withstand long-term construction erosion and has good stability.

[0015] The level is fixed to the outer wall of the cable clamp body;

[0016] A positioning plane is formed on the outer wall of the cable clamp body for fixing the level gauge;

[0017] The level is fixed on a positioning plane of the outer wall of the cable clamp body, and the centering position of the level is located at the center of the positioning plane.

[0018] The above technical measures can enable the spirit level to be stably fixed on the cable clamp without affecting the connection between the cable clamp and the main cable and the sling, and are also easy to observe.

[0019] The positioning plane is formed on the outer wall of the axial end of the cable clamp body. This technical measure is conducive to the state observation of the level.

[0020] The positioning plane is an additional pad formed on the outer wall of the cable clamp body, and the surface of the additional pad used to fix the level is a plane structure; this technical measure is conducive to the fixed formation of the level outside the cable clamp, and basically no excessive processing of the cable clamp is required, and the arrangement position of the pad on the outer wall of the cable clamp can be flexibly, easily and accurately determined. Alternatively, as an alternative, the positioning plane is a milling plane formed on the outer wall of the cable clamp body; this technical measure requires the processing of the milling plane on the outside of the cable clamp, and based on the requirements of the alignment characteristics, the operation of the cable clamp manufacturing is more troublesome.

[0021] The cable clamp body comprises a cable clamp upper half and a cable clamp lower half;

[0022] When the cable clamp body is fixed to the main cable setting position of the space cable suspension bridge, the lower half of the cable clamp is close to the bridge deck, and the upper half of the cable clamp is far away from the bridge deck;

[0023] The upper half of the cable clamp is used to connect a level gauge.

[0024] The above technical measures are aimed at the particularity of the common cable clamp structure. The spirit level is formed on the upper half of the cable clamp, which is easy to observe during construction and does not interfere with the connection of the sling.

[0025] The cable clamp body is an ear plate structure, and the ear plate used to connect the sling is convexly formed on the lower half of the cable clamp, and the thickness center extension line of the ear plate passes through the cable hole center of the cable clamp body. This technical measure ensures that the forming position of the level gauge and the forming position of the sling connected to the ear plate do not interfere with each other, and is conducive to positioning the two at a set angle.

[0026] The level is a bubble level structure and has the technical characteristics of simple structure, stable use, low cost and easy fixation.

[0027] The beneficial technical effect of the utility model is that the above-mentioned technical measures add a spirit level that matches the designed angle on the basis of the cable clamp used in the space cable suspension bridge, so that during the installation and construction process of the cable clamp, the inclined installation at a specific designed angle is formed by the centering state of the carried spirit level. Compared with the angle measurement technical means, the installation and construction operation has the technical characteristics of intuitive, convenient and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 The present invention is a schematic diagram of an existing cable clamp structure for a space cable suspension bridge.

[0029] Figure 2 It is a structural schematic diagram of the utility model.

[0030] The meaning of the codes in the figure are: 1—upper half of the cable clamp; 2—lower half of the cable clamp; 3—ear plate; 4—plumb line; 5—connecting bolt; 6—positioning plane; 7—level; 8—marking line. DETAILED DESCRIPTION

[0031] The utility model relates to a cable clamp for a suspension bridge, specifically a cable clamp for a space cable suspension bridge and equipped with a level gauge. Figure 2 The technical solution of the utility model is clearly and in detail explained.

[0032] It should be noted that the drawings of the present invention are schematic, and unnecessary details have been simplified to clarify the technical purpose of the present invention, so as to avoid blurring the technical solution of the present invention in the prior art. In addition, the expressions "approximately" and "substantially" in the following text regarding quantity or matching relationship mean that reasonable assembly errors and processing errors in the industry are allowed to exist, and do not literally express absolute quantity or matching relationship.

[0033] See also Figure 2 As shown, the cable clamp of the utility model comprises a cable clamp body, which has a cable clamp upper half 1 and a cable clamp lower half 2 which are circumferentially assembled together by a plurality of connecting bolts 5. An ear plate 3 for connecting a sling is convexly formed at the center of the outer wall of the cable clamp lower half 2, and the ear plate 3 is used to connect the sling. The thickness center extension line of the ear plate 3 basically passes through the center of the cable hole of the cable clamp body.

[0034] The upper half 1 of the cable clamp is connected with a level 7 with a bubble structure.

[0035] Specifically, a pad of a flat plate structure is added to the outer wall of the upper half 1 of the cable clamp by a welding structure, and the top side of the pad constitutes a positioning plane 6 for fixing the level gauge 7. The forming position of the positioning plane 6 at the outer wall of the upper half 1 of the cable clamp is determined by the set installation position of the current cable clamp on the main cable of the space cable suspension bridge, that is, the suspension cable connected to the cable clamp is set to form an angle α with the plumb line, then the center extension line of the positioning plane 6 and the center extension line of the thickness of the ear plate 3 form a set angle α, and the centering position of the level gauge 7 connected to the positioning plane 6 is located at the center of the positioning plane 6.

[0036] When the cable clamp is fixed at the set position of the main cable of the space cable suspension bridge at a set angle (or position), the plumb line 4 in the alignment state should form a designed angle α with the axial center of the sling connected to the cable clamp. At this time, the plumb line 4 in the alignment state should pass through the positioning platform 6 and connect to the centering position of the level 7. In this way, by observing the centering state of the bubble of the level 7, it can be intuitively judged whether the cable clamp is installed on the main cable of the space cable suspension bridge at the set angle.

[0037] The molding position of the positioning plane 6 on the upper half 1 of the cable clamp, in addition to having a specific angle requirement, should be located at the end of the upper half 1 of the cable clamp for easy observation.

[0038] Of course, in addition to adding a cushion block structure, the positioning plane on the cable clamp can also be machined and formed at the corresponding position of the outer wall of the upper half of the cable clamp by mechanical milling.

[0039] The above technical solutions are only used to illustrate the present invention, but not to limit it.

[0040] Although the present invention has been described in detail with reference to the above-mentioned specific technical solutions, those skilled in the art should understand that they can still modify the specific technical solutions in the above-mentioned specific technical solutions, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the present invention.
