Description

TECHNICAL FIELD

[0001] The utility model relates to railway contact network technical field, concretely for a tool for replacing compensation device plummet. BACKGROUND

[0002] Railway contact network compensation device is also called compensator, and its function is to automatically adjust the tension of the line in the contact suspension. When the temperature changes, the line is affected by the linear expansion coefficient and is elongated or shortened, and the plummet string is automatically adjusted under the action of its own gravity, and when the temperature is constant, the plummet is in a balanced state and does not rise or fall. When the temperature rises, the length of the bearing cable increases, and under the action of the gravity of the plummet itself, the plummet will lower with the temperature rise. Conversely, when the temperature drops, the bearing cable will be shortened, and the plummet will rise, so that the tension in the line is kept balanced.

[0003] In daily maintenance, the traditional method for replacing damaged plummet is to use a hand-operated hoist to take down one by one from top to bottom, replace the damaged plummet, and then install the plummet one by one. For example, if the 16th plummet is damaged, the upper 15 plummets are taken down one by one, the 16th damaged plummet is replaced with a new one, and then the previous 15 plummets are reset. The operation time is long, and multiple workers are needed to pass the plummets, which wastes manpower and physical energy. In the related art, a tool for replacing compensation device plummet is disclosed in the announcement No. CN208469608U. When replacing the damaged plummet, the plummets above the damaged plummet do not need to be taken down one by one, the replacement efficiency is significantly improved, the operation is safe, the labor is effectively reduced, the labor load is reduced, the structure is simple, and the manufacturing cost is low. However, after the fixing piece limiting the plummet string is removed, the lower plummet is easy to slide out from both sides of the connecting rod when the upper plummet is pulled up, causing the plummet to fall, which has certain safety hazards.

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0027] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement condition and the like between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0028] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0030] When in use, the operator uses a lever hoist to remove the weights one by one from top to bottom, replace the damaged weights, and then install the weights one by one.

[0031] In related technologies, such as the tool disclosed in CN208469608U for replacing the weights of a compensation device, when replacing a damaged weight, it is not necessary to remove the upper weights one by one, which significantly improves the replacement efficiency, is safe to operate, effectively reduces labor and workload, and has a simple structure and low manufacturing cost. However, after removing the fixing plate that limits the weight string, when the upper weight is pulled upward, the lower weight is prone to slipping out from both sides of the connecting rod, causing the weight to fall, which poses a certain safety hazard.

[0032] To address some of the problems in related technologies, this application provides a tool for replacing the weight of a compensation device. When it is necessary to replace a damaged weight 13, simply install the first clamp 21 on the outside of the uppermost weight 11, install the second clamp 22 on the outside of the weight 11 above the damaged weight 13, and tie the four pull ropes 23 to the pull rings of the second clamp 22 and pass them through the outside of the first clamp 21. The pull ring connects the pull rope 23 to the suspension rope via a lever hoist. Pulling the pull rope 23 upwards separates the upper weight 11 from the damaged weight 13, facilitating the replacement of the damaged weight 13. After pulling up the upper weight 11, simply adjust the pressure block 25 to press firmly on the weight 11 below the damaged weight 13, thus limiting the weight 11 below the damaged weight 13 and reducing the risk of the weight 11 falling.
