Through setting up the elevating gear between support frame and base, played protection elevating gear's purpose, to avoid when the dress article is transferred to the goliath, the article drops carelessly and pounds on rail clamping device, exposes in outer elevating gear is pounded by the article and produces and prostheticly to harm to influence rail clamping device's normal use.
Description
Technical field
This utility model relates to equipment running technology field, particularly to a kind of rail clamping device.
Background technology
Rail clamping device is divided into manual type and electrodynamic type two kinds, and Manual rail clamping device is generally screw, simple in construction, but clamping force is little, slow motion, is mainly used on the crane of the little middle-size and small-size or provisional purposes of the area that keeps out the wind.Goliath or harbour crane mainly use electronic rail clamping device.It is to be made clamp grip track by spring force, unclamps clamp by oil cylinder power in hydraulic system.
At present, the Chinese patent of Application No. 201310557507.2 discloses a kind of self-locking rail clamping device, it includes base, be hinged on base the clamping clip a pair with chuck and drive the retractor device that a pair clamping clip rotate, it is fixed with on described base in fairlead, described fairlead and is provided with guide post, described guide post upper end is fixed with blocker ring, bottom is provided with clamp nut, described blocker ring is hinged by a pair link rod and described clamping clip, and described guide post is set with the elastic spring between described blocker ring and described fairlead.Retractor device is cylinder or oil cylinder, although this self-locking rail clamping device ensure that under the fortuitous events such as power-off, rail clamping device is firmly clamped in orbit, cannot come off, but rail clamping device all carries out operation in outdoor, when dress object adjusted by goliath, object accidentally drops and pounds on rail clamping device, it is exposed to outer oil cylinder easily hit and produce the damage of unrepairable by object, thus affects the normal use of rail clamping device.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of rail clamping device protecting lowering or hoisting gear.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of rail clamping device, including base, bracing frame, it is hinged on base and there is chuck and the clamping clip for gripper rail, connecting rod, described connecting rod one end is hinged on clamping clip and is hinged on bracing frame away from end and the other end of base, also include being connected between base and bracing frame and drive clamping clip to move with the elastic spring realizing grip track, one end contact at the described base other end contact at support frame as described above make support frame as described above move up and down and order about clamping clip action with the lowering or hoisting gear de-orbited.
Pass through technique scheme, when the mobile rail clamping device of needs, by controlling the action of lowering or hoisting gear, thus control on bracing frame carries out on base, slide in lower direction, thus clamping clip outwards disengages or clamps under the drive of connecting rod, elastic spring is under normal circumstances, all the time outwardly against, bracing frame is made to move up, thus retaining clip clencher is in normally off, therefore the Reliability comparotive of rail clamping device is high, lowering or hoisting gear is arranged between bracing frame and base, and it is left, right both sides are equipped with clamping clip and stop, lowering or hoisting gear is formed enclosed protection, when goliath lifting object, object accidentally drops and pounds on rail clamping device, also elder generation and bracing frame, clamping clip or base contacts, avoid exposure to outer lowering or hoisting gear the most hit and produce the damage of unrepairable by object, thus affect the normal use of rail clamping device.
Preferably, described lowering or hoisting gear includes the oil cylinder being fixed on base and the output shaft being hinged on bracing frame.
Pass through technique scheme, oil cylinder is controlled by the control chamber being arranged on rail clamping device, realize oil cylinder jack-up output shaft or landing output shaft, thus by output shaft upwards, downward action drive bracing frame sliding on base, so that the chuck grip track of clamping clip, the operation of oil cylinde controlled by control chamber is convenient, and the strength of jack-up or landing output shaft is big, can effectively drive clamping clip clamping or disengage track.
Preferably, described elastic spring is provided with two, and two described elastic springs are respectively symmetrically and are positioned at lowering or hoisting gear both sides.
