Description

Technical Field

[0001] This utility model relates to the field of railway maintenance technology, and in particular to a quick-release wrench for railway maintenance. Background Technology

[0002] Railway transportation is one of the most important modes of transportation in modern society, and the safe operation and maintenance of railways are of paramount importance. To ensure the normal operation of railways, railway lines and equipment require regular maintenance and inspection, including the repair of tracks, turnouts, signaling equipment, and more. One of the most commonly used tools in railway maintenance work is the wrench, which is used to loosen or tighten bolts, nuts, and other fasteners on railway equipment.

[0003] A search revealed a Chinese patent, CN 217494077 U, which describes a quick-release wrench for railway track maintenance. The wrench includes a rail mounted on a base and a ratchet wrench. Its features include: several fixing fasteners on both sides of the rail on the upper part of the base; the rail is fixed to the base by these fasteners; fastener bolts on one side of each fastener; a sleeve fitted onto the lower part of the ratchet wrench; a connecting sleeve inserted into the lower end of the sleeve; a hexagonal sleeve fitted onto the lower end of the connecting sleeve; the inner groove of the hexagonal sleeve matching the fastener bolt; a sleeve block fitted onto the sleeve; an L-shaped block movably mounted on one side of the sleeve block; and a spacing adjustment mechanism between the L-shaped block and the sleeve block.

[0004] When railway maintenance personnel replace or maintain bolts, they need to locate the bolts and place an Allen wrench on top of them. During this process, the presence of the wrench obstructs the maintenance personnel's downward view. In order to place the Allen wrench on top of the bolt, the railway maintenance personnel need to observe the bolt's position from the side, which is inconvenient. Therefore, the above device needs to be improved. Utility Model Content
