Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery application, in particular to a rail vertical hoisting anti-dropping clamp structure. Background Art

[0002] In the scattered laying construction of urban rail transit track laying, since the length of the shield shaft feed opening in the line direction is only 11 meters, and the length of the track is 25 meters, the track cannot be hoisted and unloaded as a whole, and all track components must be hoisted from the narrow feed opening into the tunnel for underground assembly. The rail is the largest component of the track, and the vertical hoisting of the rail is the main difficulty in the "manual scattered laying" construction of track laying.

[0003] At present, in the track laying construction of urban rail transit in my country, there are problems such as unstable installation of rail lifting fixtures, easy loosening of fixtures during lifting, complicated installation steps and laborious disassembly. Utility Model Content

[0004] The purpose of the utility model is to overcome the problem that during the vertical lifting operation of the rails in the existing urban track laying construction, the rail lifting fixtures are easy to loosen or even fall off, causing serious safety injuries to the construction personnel, and the installation and disassembly of the lifting fixtures are complicated. A rail vertical lifting anti-falling fixture structure is provided to improve the safety of the vertical lifting operation of the rails and the convenience of the installation and disassembly of the fixtures.

[0005] In order to achieve the above-mentioned purpose, a rail vertical lifting anti-dropping clamp structure is designed, including a first clamp body, the first clamp body includes a vertically arranged first main body, the upper part of the first main body has a transversely extending first connecting part, and the middle part of the first connecting part is provided with a groove; a second clamp body, the second clamp body includes a vertically arranged second main body, the upper part of the second main body has a transversely extending second connecting part, the position of the second connecting part matches the groove of the first connecting part of the first clamp body; a wedge is arranged below the first connecting part and the second connecting part; a bolt passes through the second connecting part from the top of the first connecting part of the first clamp body and then tightens the wedge.

[0006] Preferably, in the present invention, a first clamping portion is provided at the bottom of the first main body, and a second clamping portion is provided at the bottom of the second main body opposite to the first clamping portion, and the first clamping portion and the second clamping portion are used to clamp the waist of the rail.

[0007] Preferably, the wedge of the utility model is located between the top of the rail and the first connecting portion, and after the first clamping body and the second clamping body are connected by bolts, the wedge and the top of the rail are tightened.

[0008] Preferably, the top of the first clamp of the utility model is also provided with a wire rope connection ring.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] 1. A wedge and a clamp body that fit the shape of the rail are provided. The wedge is supported by bolts so that the contact surface of the clamp body, the wedge and the rail fits tightly, increasing friction and playing an anti-slip effect.

[0011] 2. The clamp and wedge adopt a split structure design and can be installed directly from any position above the rail.

[0012] 3. Easy installation and disassembly, which is conducive to rapid construction work on site. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the purpose, principle and structure of the utility model clearer, it is further described below in conjunction with the drawings and specific embodiments.

[0021] like Figure 2 , Figure 4 , Figure 5As shown, the utility model provides a rail vertical lifting anti-dropping fixture structure, the fixture adopts a split structure design, the second fixture body 3 can be inserted into the first fixture body 2, and can be assembled into one by bolts 5. The first fixture body 2 is an F-shaped structure, the first fixture body 2 is vertically provided with a first main body 2.1, the first main body 2.1 is horizontally extended above the first main body 2.2, and the first connecting part 2.2 is provided with a groove 2.4. The second fixture body 3 is a J-shaped structure, the second fixture body 3 is vertically provided with a second main body 3.1, the second connecting part 3.2 is horizontally extended at the upper end of the second main body 3.1, and the second connecting part 3.2 can be tightly engaged with the groove 2.4.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, the wedge 4 is installed inside the first clamp body 2 and the second clamp body 3 and fits with the top of the rail head of the rail 1; the first clamp body 2 and the second clamp body 3 have bolt holes 7 on the upper part, and the wedge 4 is tightened by bolts 5 to clamp the rail; the contact surface of the first clamp body 2, the second clamp body 3, the wedge 4 and the rail head of the rail 1 adopts a curvature design that fits the rail head of the rail 1, so that the clamp can fit tightly with the rail head, as shown in FIG. Figure 6 As shown, the bottom of the wedge 4 is concave and fits the shape of the rail head; the bolt 5 has two functions, one is to fix the connection between the clamp body 2 and the clamp body 3, and the other is to press the wedge 4 to clamp the rail. The lower ends of the first clamp body 2 and the second clamp body 3 are also provided with a first clamping part 2.3 and a second clamping part 3.3, and the clamping part is a convex structure, which can be tightly matched and pressed with the rail waist.

[0023] The specific usage is:

[0024] At a distance of 5.5 meters from the end of the rail, place the groove of the wedge 4 on the rail head, clamp the first clamp body 2 on the upper part of the wedge (4), insert the second clamp body 3 into the first clamp body 2 and clamp the rail head at the same time, use two bolts 5 to pass through the bolt holes of the first clamp body 2 and the second clamp body 3, and tighten the wedge 4 to make it fit tightly on the rail head. The two bolts need to be tightened to increase the contact surface pressure and thus increase the friction to prevent the rail from falling off. Finally, connect the hoist wire rope to the lifting ring 6 to complete the overall installation of the rail vertical lifting anti-falling clamp.
