Description

A kind of rail meter

Technical field

A kind of rail meter is the utility model is related to, prevents tower wagon from turning on one's side in being constructed for railway contact line.

Background technology

In the contact network construction of railway, tower wagon is one of conventional power tool, in view of rail track there is ramp, The features such as curve, how to ensure the security of tower wagon in contact net operation, so that it is guaranteed that operating personnel is high in tower wagon top safety The construction of effect, it is always the direction that researcher updates application.

There is the rail meter of compression type in the prior art, see Patent No. 201520335214.4, patent name fills for clamp rail The Chinese utility model patent put, it discloses a kind of clamp rail device, sees Fig. 1, including the U-shaped frame 10 that can be enclosed on rail and The clamping screw 20 of the two sides of U-shaped frame 10 is arranged on, is locked clamp rail device and rail 30 by adjusting clamping screw 20.But This structure progressively fastens by using screw thread, and when pinning rail, the time is longer, and operation is cumbersome；And the pressing plate of rail meter and two Cant board limited angle system, when stress is excessive, the easy stripped thread of bolt, stability is poor, and riser stress is bad.

Utility model content

Deficiency, the technical problems to be solved in the utility model are to provide a kind of rail meter, may be mounted at ladder based on more than Che Shang, rail meter by rail clamping, can ensure the steadiness of tower wagon in contact network construction operation, and rail meter stress is small, The damage to rail meter can be reduced, can fully ensure that rail meter Stability Analysis of Structures, greatly prolongs its service life.

In order to solve the above technical problems, the utility model employs following technical scheme：

A kind of rail meter, including shell, movement, handle and hook hand, the movement are arranged in the shell；The handle It is connected through the shell with the movement；The hook hand is arranged in pairs in the both sides of the movement, and the hook hand includes stirring Portion, articulated section and the clamping section that rail is clamped during for rotating, the hinge point is in the clamping section and the clicking section Between and with the housing hinge；The clicking section is located in the movement.

Through hole is provided with the movement, the clicking section of the hook hand is located at the both ends of the through hole respectively.

Chute or slide opening are provided with the hole wall of the through hole, is provided with the clicking section along the chute or slide opening The slide post of slip.

The projection that the clicking section is set for the prominent articulated section.

The clamping section is voussoir.

Bayonet lock is provided with the handle, the pin-and-hole being adapted with the bayonet lock shape is provided with the shell.

The handle is threadedly coupled with the movement.

Also include steel plate, the first hinge, the second hinge and bearing pin, the steel plate and the cage connection, described first Hinge is connected with the steel plate, and second hinge is hinged with first hinge, first hinge and second hinge On be additionally provided with screw.

First hinge and second hinge are arc, and are oppositely arranged.

Using above technical scheme, the utility model achieves following technique effect：

(1) rail meter provided by the utility model, is moved up by handle, drives the movement that is connected with handle to moving up Dynamic, movement drives hook hand to rotate, and the clamping section of hook hand is drawn close rail clamping to rail both sides；Moved down by handle, band The dynamic movement being connected with handle is moved down, and so as to drive hook hand to rotate, the clamping section of hook hand is opened rail to rail both sides Unclamp, moving up and down can only by operating handle realizes Quick-clamped with unclamping；The device is using vertically simultaneously Stress, the stress condition of device in itself is improved, rail meter stress is small, can reduce and rail meter is damaged, can fully ensure that clamp rail Device Stability Analysis of Structures, greatly prolong its service life；

(2) chute or slide opening of guiding clicking section action are set on movement, can be transported with limit slippage post along both fixed tracks It is dynamic, prevent when movement roof does not contact also with hook hand, hook hand avoids band without constraining and can arbitrarily being acted in certain angle Come the risk damaged.

(3) bayonet lock is set on handle, after lift-pull handle clamps rail, then by rotating handles by bayonet lock turn to Pin-and-hole is at an angle, it is possible to fixes movement position, hook hand keeps clamping the state of rail；Also, handle and movement spiral shell Line connects, and movement can be driven to move up further for rotating handles until hook hand is in close contact with rail, and realization fine setting is steady to increase Solidity, the mode of operation are more simple and efficient；

(4) connecting rod of tower wagon chassis is placed between the first connector and the second connector, can be by mutually by bolt Rail meter, can be connected by the first be hinged connector and the connection of the second connector with tower wagon.
