Rail clamping device

Abstract

The rail clamping device comprises a clamping base, a connecting base and a reverse hooking wheel base, baffles are arranged on the two sides of the clamping base, an X-shaped cavity is formed between the baffles on the two sides, a wedge block is arranged in the cavity formed by the baffles on the two sides, the wedge block is provided with an inclined face, the inclined face of the wedge block makes contact with the inclined face of the inner wall of the cavity formed by the baffles, and the other face, opposite to the inclined face of the wedge block, of the wedge block is a working face. The working surface is contacted with the side surface of the track; the connecting seat is fixedly connected with the clamping seat, the connecting seat is located at least one end of the clamping seat, and the connecting seat is used for being connected with a driving mechanism; the reverse hooking wheel base is fixedly connected with the connecting base and located below the connecting base, and reverse hooking wheels are arranged on the two sides of the reverse hooking wheel base and used for being hooked to the lateral lower portion of a track. And through the combination of the clamping seat and the reverse hooking wheel seat, the equipment is prevented from overturning. The structure of the four wedge blocks is arranged, so that bidirectional fixation can be realized, and the device is particularly suitable for large-scale pushing and jacking equipment, such as bridge pushing construction, construction of large-scale creeping formworks and stair climbing machines, and other working conditions.

Description

technical field [0001] The present invention relates to a locking and fixing device, in particular to a rail clamp. Background technique [0002] In the process of engineering construction, some equipment or components need to move along the track, and during the movement, to fix the equipment or components, the rail clamp is usually used as the fixed part. In the rail clamp, the use of wedges is more common. structure. For example the structures in CN 112897336 A, CN 111674861 A and CN 213707535 U. However, the above structure can only be fixed during one-way movement, which is relatively inconvenient to use. CN 106567550 A describes a fully automatic two-way hydraulic rail clamp, wherein two-way wedges are used to achieve fixation, and the wedge is driven by the opening and closing action of the wedge sliding oil cylinder. The solution has the following Defects, one is that the fixed action of the rail clamp is driven by the wedge sliding cylinder, that is, if the wedge...

However, the above structure can only be fixed during one-way movement, which is inconvenient to use

In CN 106567550 A, a full-automatic two-way hydraulic rail clamp is described, in which a two-way wedge is used for fixing, and the wedge is driven by the opening and closing action of the inclined wedge sliding cylinder. This scheme has the following Defects, one is that the fixing action of the rail clamp is driven by the wedge sliding cylinder, that is, if even one side of the wedge sliding cylinder fails, it may lead to a major safety accident

The second is that the structure is relatively complex, especially during the fixing process, the shell is subjected to a large force, and the overly complex structure leads to an increase in volume

The fourth is to increase the control parts of the oblique wedge sliding cylinder, that is, each push needs to control the action of two oblique wedge sliding cylinders, which increases the difficulty of control
