Description

TECHNICAL FIELD

[0001] The present application relates to the field of cable saddle structure, in particular to a roller type saddle, a cable saddle and a method for prolonging the service life of the cable saddle. BACKGROUND

[0002] The cable saddle is used in the fields of bridge, ship (the force direction of the cable or hoisting system is handled by using the structure similar to the cable saddle), large hoisting equipment (the force distribution of the cable is optimized by using the "cable fixing" function of the cable saddle), etc., especially in the field of bridge, the cable saddle is an important core component of the bridge. In the construction stage and the operation stage, the cable force difference of the side and anchor span main cable is caused by factors such as impact dynamic load and temperature change, thereby causing the longitudinal displacement of the cable saddle. Therefore, the bottom of the saddle head needs a structure that can move or swing the saddle head in the longitudinal direction, so that the cable force of the side and anchor span main cable is balanced in the new position. The longitudinal direction is the length direction of the single cable.

[0003] The commonly used cable saddle at present is a roller type cable saddle, and the roller assembly in the roller type cable saddle is the structure that provides movement or swing, such as the roller assembly mentioned in the Chinese utility model patent with the publication number CN220394292U. The roller assembly mainly has a plurality of rollers. In the long-term application process of the roller type cable saddle, the following disadvantages are found: 1. The weight and volume of the roller are large, usually reaching several tons, so it is difficult to process and heat treat, the consistency of the size of the roller is difficult to control, and the stability of the movement or swing of the saddle head in the longitudinal direction is low. 2. The roller mentioned in the above patent is inserted into the holes in the side walls of the base or the holes in the support plates on the two sides of the base. After the bridge is completed, the side walls or support plates of the base cannot be disassembled (because all the rollers are supported by the side walls or support plates of the base), which leads to the fact that the roller cannot be replaced when it is worn out, and the service life of the roller type cable saddle is limited.

[0004] Therefore, in order to solve the problems existing in the roller type cable saddle at present, a new cable saddle structure needs to be proposed. SUMMARY

[0005] The purpose of the present application is to provide a roller type saddle, a cable saddle and a method for prolonging the service life of the cable saddle, so that the structure that enables the saddle head to move in the longitudinal direction is easy to process and manufacture, and the service life of the cable saddle is less limited.

[0006] The technical scheme adopted by the present application is as follows: A roller type saddle comprises a lower supporting plate, a plurality of groups of sliding grooves are arranged on the lower supporting plate, the length direction of the sliding grooves is along the transverse direction, the two ends of the sliding grooves are not closed, a plurality of roller seats are detachably and slidably connected in each sliding groove, and a roller is supported on each roller seat; all the rollers can rotate in the longitudinal direction; a side baffle is detachably connected on the lower supporting plate, and the side baffle is located at the two ends of the sliding groove to constrain the roller seat in the sliding groove.

DETAILED DESCRIPTION

[0018] In the description of the present application, it should be noted that if the terms “center”, “upper”, “lower”, “left”, “right”, “vertical”, “horizontal”, “inner”, “outer” and the like appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship when the product of the specification is usually placed, and is only for the convenience of describing the specification and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the specification.

[0019] Furthermore, the use of terms such as "horizontal" and "vertical" in this specification does not necessarily imply that a component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply refers to a direction that is more horizontal than "vertical," and does not imply that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0020] In the description of this specification, it should also be noted that, unless otherwise clearly stipulated and limited, the terms "setting", "installation", "connection" and "connection" should be understood in a broad sense. For example, the connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection between the internal parts of two components.

[0021] Example 1 like Figures 1-7 As shown, a roller saddle can be applied to a loose rope saddle, including a lower supporting plate 6, on which a plurality of chutes 61 are provided. The length direction of the chutes 61 is along the transverse direction, and the two ends of the chutes 61 are not closed. A plurality of roller seats 51 are placed in each chute 61, and each roller seat 51 supports a roller 5; all rollers 5 can rotate in the longitudinal direction; the lower supporting plate 6 is detachably connected to a side baffle 2, which is located at both ends of the chute 61 to constrain the roller seat 51 in the chute 61.

[0022] In this embodiment, the length direction of the chute 61 is in the horizontal direction, that is, perpendicular to the longitudinal direction. This setting is to rely on the groove wall of the chute 61 to constrain the roller seat 51 in the chute 61, that is, to avoid the situation where "the roller 5 on the roller seat 51 is displaced along the longitudinal direction when it rotates vertically", thereby achieving the stability of the position of the roller seat 51.

[0023] In this embodiment, the side baffle 2, on the one hand, constrains the pommel 1 and limits the side of the pommel 1 to prevent the pommel 1 from lateral displacement; on the other hand, the side baffle 2 closes both ends of the slide 61 to keep the roller seat 51 in the slide 61 to prevent the roller seat 51 from sliding off from both ends of the slide 61 after the bridge is formed.

[0024] Extending the life of a cable saddle primarily relies on replacing the structure that provides longitudinal motion for the pommel 1 (the roller mentioned in the background or the roller 5 in the present invention) and the wear plate 4. However, for the roller-type cable saddles mentioned in the background, neither the roller nor the wear plate 4 can be replaced. The present invention effectively solves this technical problem by making the roller 5 replaceable, thereby extending the life of the cable saddle beyond the life of the structure that provides longitudinal motion for the pommel 1 and reducing service life limitations. The details are as follows.

[0025] In this embodiment, the two ends of the chute 61 are not closed, that is, after the side baffle 2 is removed and the saddle head 1 is jacked up, the saddle head 1 is no longer in contact with the roller 5, and the roller seat 51 in the chute 61 can slide out of the two ends of the chute 61 with the roller 5, that is, the roller 5 can be replaced; after replacing the roller 5, the roller seat 51 is sent into the chute 61 from the two ends of the chute 61 again, so that the roller seat 51 and the roller 5 are returned to the original position, the saddle head 1 is lowered, and the side baffle 2 is installed, that is, the replacement of the roller 5 is completed.

[0026] It should be noted that, first, the process of jacking up the saddle head 1 only needs the bottom surface of the saddle head 1 to be separated from the contact with the roller 5, without the need for excessive jacking up. For the saddle head 1 that has already formed a bridge, even if the load borne by the saddle head 1 and the saddle head 1 is a ton-level weight, the operation is still feasible, and will not have any impact on the bridge. This effect is due to the design of the roller 5.

[0027] In summary, the technical scheme provided by the embodiment uses the roller 5 as a structure for providing longitudinal movement for the saddle head 1. The weight of a single roller 5 is only a few kilograms, which is light in weight and small in size, easy to process and heat treat, and convenient for size control, thereby improving the size consistency of all rollers 5 and the stability of the movement and swing of the saddle head 1 in the longitudinal direction. Through the above-described roller 5 replacement, the service life of the cable saddle is effectively reduced, and the purpose of prolonging the service life of the cable saddle is achieved.

[0028] Embodiment 2 On the basis of embodiment 1, a specific implementation manner is further proposed.

[0029] A feasible implementation manner is that the roller seat 51 is U-shaped, so that the roller 5 has a space for rotation; the support arms at both ends of the roller seat 51 support the roller 5 through bearings, thereby improving the stability and smoothness of the rotation of the roller 5.

[0030] A feasible implementation manner is that the support arms have U-shaped notches, and the bearings are installed in the notches, which can avoid the roller 5 from falling off and can realize quick disassembly and installation of the roller 5.

[0031] A feasible implementation manner is that all the roller seats 51 arranged in a rectangular array are arranged on the lower supporting plate 6, so as to provide uniform support force and make the support force of the roller 5 supporting the saddle head 1 uniformly distributed.

[0032] A feasible implementation manner is that the end face baffle 3 is further fixed on the lower supporting plate 6, the end face baffle is arranged in the longitudinal direction, and all the chutes 61 are located between the end face baffles 3. The saddle seat is a structure for supporting the saddle head 1, and the saddle head 1 is placed on the saddle seat. The end face baffle 3 is arranged to limit the end face of the saddle head 1 and avoid the displacement of the saddle head 1 in the longitudinal direction being too large.

[0033] A feasible implementation also includes pre-embedded grid 7, the lower plate 6 is installed on the pre-embedded grid 7, which can be connected by pin, bolt and the like.

[0034] Embodiment 3 As Figures 1-7 shown, a cable saddle, which can be a spreader saddle, includes a saddle head 1 and a roller 5 type saddle described in any one of embodiments 1-2, the saddle head 1 is placed on the saddle, and the bottom of the saddle head 1 is supported by all the rollers 5, all the rollers 5 can rotate longitudinally to provide a feasible basis for the longitudinal movement of the saddle head 1.

[0035] It should be noted that other structures of the saddle head 1 are known to those skilled in the art, and will not be described in detail in this specification.

[0036] A feasible implementation, the bottom of the saddle head 1 is equipped with a wear plate 4, which is in contact with the roller 5, increasing the wear resistance of the bottom of the saddle head 1 and improving the service life of the cable saddle.

[0037] As Figures 5-7 shown, regarding the assembly of the wear plate 4, the following feasible implementations are proposed in this embodiment.

[0038] The first implementation is that the wear plate 4 is fixed on the bottom surface of the saddle head 1 by screws or bolts, and the wear plate 4 covers the entire bottom surface of the saddle head 1.

[0039] The second implementation is to open an installation groove on the bottom surface of the saddle head 1, and the wear plate 4 is installed in the installation groove.

[0040] For the second implementation, the installation groove can be one or multiple; when the number of installation grooves is one, the groove bottom area is close to the bottom surface area of the saddle head 1; when the number of installation grooves is multiple, the distribution of the installation grooves can be consistent with the distribution of the roller seats 51 in the sliding groove 61.

[0041] A feasible implementation, the side baffle 2 is located on the side of the saddle head 1 and is attached to the side of the saddle head 1, the side baffle 2 limits the saddle head 1 to avoid horizontal displacement of the saddle head 1; the end baffle 3 is located on the end surface of the saddle head 1, and there is a gap between the end baffle 3 and the end surface of the saddle head 1, which can be determined according to the size of the movement required by the design of the saddle head 1 to meet the movement of the saddle head 1 in accordance with the design.

[0042] Embodiment 4 A method for prolonging the service life of a cable saddle, applied to the cable saddle described in embodiment 3, uses un-worn rollers 5 to replace worn rollers 5, and the worn rollers 5 on the cable saddle are replaced, through the replacement of the rollers 5, to achieve the purpose of prolonging the service life of the cable saddle, including the following steps: A1: dismount the side baffle 2, use the jack to lift the saddle head 1 until the bottom surface of the saddle head 1 is separated from the roller 5, usually a gap of 1-3mm is enough; A2: use a tool (such as a long rod) to push the roller seat 51 with the roller 5 needing to be replaced out of the sliding groove 61 on the lower bearing plate 6; A3: remove the roller 5 and bearing needing to be replaced on the roller seat 51 and replace them with new ones; A4: return the roller seat 51 with the new roller 5 and bearing to the original position one by one; A5: after all the rollers 5 are replaced, remove the force of the jack, put down the saddle head 1, install the side baffle 2, and complete the replacement of the worn rollers 5 on the cable saddle.

[0043] The present application is not limited to the foregoing specific embodiments. The present application extends to any novel one, or any new combination, of the characteristics disclosed in this specification, as well as to any novel method or process disclosed in any step, or any new combination, of the steps of the disclosed methods or processes.
