Description

Technical Field

[0001] The utility model relates to the technical field of rail hoisting, in particular to a novel railway rail hoisting tool. Background Art

[0002] Due to the heavy pressure, rails are prone to fatigue damage and excessive wear, and even fracture, seriously endangering the safety of locomotive transportation. By replacing the rails, these hidden dangers can be eliminated in time.

[0003] The original hoisting method is that in the preparatory work for replacing the rails, before the hoisting operation, the rails are artificially padded at the bottom, the steel wire rope is passed through the bottom of the rail, and then fixed with a U-shaped ring for hoisting operation. However, when the steel wire rope is in use, the steel wire rope causes side wear on the top and bottom parts of the rail, resulting in rail damage; before hoisting, the steel wire rope needs to be passed through the bottom of the rail. If there is no gap left at the bottom in advance, it needs to be artificially padded, increasing the labor cost; the bottom of the rail is prone to cut and wear the steel wire rope, causing the steel wire rope to break and a falling accident to occur. Summary of the Utility Model

[0004] The utility model provides a novel railway rail hoisting tool to solve the technical problem of high labor cost in the existing rail hoisting.

[0005] To solve the above problems, a novel railway rail hoisting tool provided by the utility model adopts the following technical scheme:

[0006] A novel railway rail hoisting tool includes a connecting piece, the upper end of which is used for connecting with a hook; a fixed clamping plate is arranged on the connecting piece; a movable clamping plate is symmetrically arranged with the fixed clamping plate on the connecting piece in the front-back direction, and the movable clamping plate is detachably connected to the connecting piece through a first bolt and a second bolt; both the fixed clamping plate and the movable clamping plate are L-shaped plates, and the fixed clamping plate and the movable clamping plate are used for being inserted into the grooves on both sides of the rail to clamp the rail.

[0007] The beneficial effects are as follows: When the novel railway rail hoisting tool of the utility model is in use, first connect the upper end of the connecting piece with the hook, then remove the second bolt or the first bolt. At this time, rotate the movable clamping plate to an appropriate angle, then clamp the fixed clamping plate in the groove on one side of the rail, and then rotate the movable clamping plate until the movable clamping plate is clamped in the groove on the other side of the rail, so that the fixed clamping plate and the movable clamping plate clamp the rail. At this time, install the second bolt or the first bolt to fix the movable clamping plate. When all the hoisting tools are clamped on the rail, the crane can be started to lift the rail. When the novel railway rail hoisting tool of the utility model is in use, the structure is simple, it does not need to pass through the bottom of the rail but is clamped in the grooves on both sides of the rail, reducing the labor of workers and the labor cost.

[0008] Further, the connecting member is a triangular plate-like structure, and a slot penetrating the connecting member in the front-rear direction is formed in the connecting member, and both the fixed clamping plate and the movable clamping plate are arranged in the slot.

[0009] Beneficial effects: The connection is stable, preventing the fixed clamping plate and the movable clamping plate from shaking in the left-right direction, and ensuring the stability of the fixed clamping plate and the movable clamping plate.

[0010] Further, when the movable clamping plate is fixed to the connecting member by the first bolt and the second bolt, the upper end surface of the movable clamping plate abuts against the upper groove wall of the slot.

[0011] Beneficial effects: Improve the stability of the movable clamping plate when clamping the rail, reduce the stress on the first bolt and the second bolt, and improve the service life of the first bolt and the second bolt.

[0012] Further, the fixed clamping plate is integrally formed and connected with the connecting member.

[0016] Further, the lifting ring is connected to the connecting member by a third bolt. The lifting ring includes an arc-shaped section for connecting with a hook and two clamping sections respectively connected to the left and right sides of the lower end of the arc-shaped section, and the two clamping sections clamp on the left and right sides of the connecting member.

[0017] Beneficial effects: The structure is simple and convenient for disassembly and storage.

[0018] Further, buffer protection pads are provided on the opposite sides of the fixed clamping plate and the movable clamping plate.

[0019] Beneficial effects: Protect the rail from damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] As Figure 1 and Figure 3 shown, the connecting member 1 is a triangular plate-like structure, and a slot 6 penetrating the connecting member 1 in the front-rear direction is formed on the connecting member 1. The connecting member 1 is also provided with a first fixing hole 10 and a second fixing hole 11, and the first fixing hole 10 and the second fixing hole 11 penetrate the connecting member 1 and the slot 6 in the left-right direction. A third fixing hole 14 penetrating the connecting member 1 in the left-right direction is further formed on the connecting member 1 at the upper end of the slot 6.

[0032] The suspension ring 7 includes an arc segment for connecting with a hook and two clamping segments respectively connected to the left and right sides of the lower end of the arc segment. The two clamping segments clamp on the left and right sides of the connecting member 1, and coaxial third through holes are formed in both clamping segments, and the third through holes are coaxially adapted to the third fixing holes 14.

[0033] The third bolt 8 is used to sequentially pass through the third through hole and the third fixing hole 14 to connect the suspension ring 7 with the connecting member 1 together.

[0034] The fixed clamping plate 2 is an L-shaped plate, and the upper end of the fixed clamping plate 2 is integrally formed and connected to the lower end of the front side of the connecting member 1.

[0035] As Figure 2 and Figure 3 shown, the movable clamping plate 3 and the fixed clamping plate 2 are symmetrically arranged on the connecting member 1 in the front-back direction. The movable clamping plate 3 is an L-shaped plate, and an insertion segment is further connected to the upper end of the vertical segment of the movable clamping plate 3. The insertion segment is used to insert into the slot 6, and a first through hole 12 adapted to the first fixing hole 10 and a second through hole 13 adapted to the second fixing hole 11 are formed in the insertion segment. When the first through hole 12 is coaxial with the first fixing hole 10, the second through hole 13 is coaxial with the second fixing hole 11, and at the same time, the upper end of the movable clamping plate 3 abuts against the upper groove wall of the slot 6 to improve the stability of the movable clamping plate 3.

[0036] The first bolt 4 is adapted to the first through hole 12 and the first fixing hole 10, and the first bolt 4 is used to pass through the first through hole 12 and the first fixing hole 10 to fix the movable clamping plate 3 in the slot 6.
