Description

Technical Field

[0001] The utility model relates to the field of grooved rail steel transport tools, in particular to a transport clamp for grooved rail steel. Background Art

[0002] Grooved rail steel, also known as head grooved rail, is a complex asymmetric cross-section rail, mainly used for urban tram tracks. When laying grooved rail steel, due to the complex working environment, some lifting equipment cannot be used, which requires manual transportation of the grooved rail steel to the designated location. When manually lifting the grooved rail steel with the hand, it is easy to cause damage to the hand due to the small effective contact area between the hand and the grooved rail steel, and the friction between the grooved rail steel and the hand is small, which can easily cause the grooved rail steel to slip and cause safety accidents; and manually tying the grooved rail steel with ropes and lifting the grooved rail steel with the help of ropes can avoid safety accidents to a certain extent, but when using ropes to tie the grooved rail steel, it is necessary to ensure that the ropes are firmly tied to the grooved rail steel, which is not only cumbersome to operate, but also increases the labor intensity of manual operation.

[0003] Therefore, there is an urgent need for a handling fixture for handling grooved rail steel that can be quickly clamped on the grooved rail steel and is convenient for manual gripping. Utility Model Content

[0004] The utility model aims to provide a handling clamp for grooved rail steel, which can quickly clamp the lower side of the rail lip and the lower side of the rail head on the grooved rail steel by turning over the first holding arm or the second holding arm, and is convenient for operators to hold.

[0005] In order to achieve the above-mentioned object, the technical solution adopted by the utility model is: a handling fixture for grooved rail steel, comprising a first holding arm and a second holding arm hinged to each other;

[0006] The first supporting arm and the second supporting arm are both in the shape of fish hooks;

[0007] Among them, the first short arm on the first supporting arm can buckle the lower side of the rail lip of the grooved rail steel, the second short arm on the second supporting arm can be flipped to abut against the lower side of the rail head on the grooved rail steel, and the second long arm on the second supporting arm can be synchronously flipped to below the first long arm on the first supporting arm.

[0008] In a preferred embodiment of the utility model, the second long arm is hinged with a lifting ring arranged around the outer periphery of the first long arm, the lifting ring is a closed-loop structure, and the first supporting arm is provided with a limiting groove capable of embedding the lifting ring.

[0009] In a preferred embodiment of the present invention, the inner side of the first short arm is arc-shaped.

[0010] In a preferred embodiment of the present invention, the first supporting arm and the second supporting arm are hinged via a pin.

[0011] In a preferred embodiment of the present invention, the first supporting arm and the second supporting arm are integrally formed.

[0012] In a preferred embodiment of the present invention, reinforcing ribs are provided at the bending parts of the first supporting arm and the second supporting arm.

[0013] The beneficial effects of the utility model are:

[0014] (1) The first holding arm and the second holding arm can be clamped on the lower side of the rail head and the lower side of the rail lip on the grooved rail steel by flipping and other actions, so that the handling fixture can be quickly clamped on the grooved rail steel. The operator only needs to hold the first holding arm and the second long arm on the second holding arm to lift the grooved rail steel with force, which is simple to operate and convenient for the operator to use;

[0015] (2) When the first supporting arm and the second supporting arm are clamped on the grooved rail steel, the lifting ring is turned over so that a section of it is embedded in the limit slot, which can limit the reverse flipping of the second supporting arm under the gravity of the grooved rail steel, so that the operator only needs a small holding force to ensure that the first supporting arm and the second supporting arm can be stably clamped on the grooved rail steel, thereby increasing its safety during use;

[0016] (3) By providing a lifting ring on the second supporting arm, it is also possible to facilitate the connection of the carrying clamp with the lifting equipment through a rope or the like when the lifting equipment can be used normally. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0025] It should be noted that if there are directional indications (such as up, down, bottom, top, etc.) involved in this embodiment, the directional indication is only used to explain the relative position relationship, movement, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. Unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two components.

[0026] like Figure 1-Figure 5 As shown, a handling fixture for grooved rail steel comprises a first holding arm 1 and a second holding arm 2 which are hinged to each other;

[0027] The first supporting arm 1 and the second supporting arm 2 are both in the shape of fish hooks;

[0028] Among them, the first short arm 101 on the first supporting arm 1 can buckle the lower side of the rail lip of the grooved rail steel, the second short arm 201 on the second supporting arm 2 can be flipped to abut against the lower side of the rail head on the grooved rail steel, and the second long arm 202 on the second supporting arm 2 can be synchronously flipped to below the first long arm 102 on the first supporting arm 1.

[0029] Specifically, Figure 3As shown, the fishhook-shaped first supporting arm 1 and the second supporting arm 2 can better adapt to the unique shape of the grooved rail steel, and the first long arm 102, the second long arm 202, the first short arm 101, and the second short arm 201 are arranged so as to increase the force between the first supporting arm 1, the second supporting arm 2 and the grooved rail steel through the lever action. When in use, the mutually hinged first supporting arm 1 and the second supporting arm 2 can be clamped on the lower side of the rail head and the lower side of the rail lip on the grooved rail steel by flipping and other actions. The operator can hold the first long arm 102 and the second long arm 202 on the first supporting arm 1 and the second supporting arm 2, so that the second short arm 201 on the second supporting arm 2 can be pressed against the lower side of the rail head on the grooved rail steel, thereby causing the inner side of the first short arm 101 to be pressed against the lower side of the rail lip of the grooved rail steel, so that the handling fixture is clamped on the grooved rail steel. The handling fixture in the technical solution can be quickly and firmly clamped on the grooved rail steel, is easy to operate, and is also convenient for manual gripping and operation.

[0030] Further, such as Figure 2 , Figure 3 , Figure 5 As shown, the second long arm 202 is hinged with a lifting ring 3 arranged around the outer periphery of the first long arm 102, and the lifting ring 3 is a closed-loop structure, and the first supporting arm 1 is provided with a limiting slot 103 in which the lifting ring 3 can be embedded. After the first supporting arm 1 and the second supporting arm 2 are clamped on the grooved rail steel, when the operator lifts the grooved rail steel by holding the second long arm 202 on the first supporting arm 1 and the second supporting arm 2, due to the large dead weight of the grooved rail steel, the operator needs to strengthen the grip of the handling fixture with his hands to ensure that the handling fixture is firmly clamped on the grooved rail steel. By flipping the lifting ring 3 so that a section of the lifting ring 3 is embedded in the limiting slot 103, the second supporting arm 2 can be limited from flipping in the opposite direction under the action of the gravity of the grooved rail steel, ensuring that the handling fixture can be firmly clamped on the grooved rail steel, thereby reducing the labor intensity of the operator. As shown Figure 2 As shown, when the lifting ring 3 is erected, it can also serve as a connecting buckle for cooperating with the lifting equipment, so as to facilitate the connection of the carrying clamp with the lifting equipment through ropes or the like.

[0031] The above, such as Figure 1 , Figure 2 , Figure 4 As shown, the lifting ring 3 will limit the maximum angle of the second supporting arm 2 relative to the first supporting arm 1. Within this angle range, the opening and closing angle between the first supporting arm 1 and the second supporting arm 2 is sufficient to meet the use requirements. At the same time, multiple limit slots 103 can be provided on the first supporting arm 1. For different types of grooved rail steel, the angle required for the second supporting arm 2 to flip is also different. By providing multiple limit slots 103, the handling fixture can be conveniently adapted to various working environments.

[0032] Further, such as Figure 1-Figure 4As shown, the inner side of the first short arm 101 on the first supporting arm 1 is arc-shaped. The arc-shaped short arm can better abut against the lower side of the rail lip on the grooved rail steel, thereby increasing the stability when the grooved rail steel is transported by the transport fixture.

[0033] In this embodiment, if Figure 1 As shown, the first supporting arm 1 and the second supporting arm 2 are hingedly connected via a pin 4. The pin 4 has high strength and low cost, and can ensure the strength of the hinge between the first supporting arm 1 and the second supporting arm 2.

[0034] Further, such as Figure 4 , Figure 5 As shown, the first supporting arm 1 and the second supporting arm 2 are integrally formed to reduce the manufacturing cost. At the same time, the bending parts of the first supporting arm 1 and the second supporting arm 2 are both provided with reinforcing ribs 5. The width or thickness of the reinforcing ribs 5 is greater than that of other parts, which can enhance the structural strength of the first supporting arm 1 and the second supporting arm 2.

[0035] Working principle: The first supporting arm 1 and the second supporting arm 2 which are hinged to each other can be clamped on the lower side of the rail head and the lower side of the rail lip on the grooved rail steel by flipping and other actions. The operator can hold the first supporting arm 1 and the second long arm 202 on the second supporting arm 2 to make the second short arm 201 on the second supporting arm 2 abut against the lower side of the rail head on the grooved rail steel, thereby causing the end of the first supporting arm 1 to abut against the lower side of the rail lip of the grooved rail steel, so that the handling fixture can be quickly clamped on the grooved rail steel and is also convenient for the operator to hold.

[0036] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
