Description
Technical field
The utility model belongs to the drg field, relates in particular to a kind of brake equipment of portal crane.
Background technology
The windproof dependence anti-wind brake of portal crane mode of operation is equivalent to the brake actuator of automobile, and brake equipment commonly used has cart to drive speed end drg, rail clamping device, three kinds of forms of rim brake.The principle of work of rail clamping device is for being fixed on rail clamping device clamp on the hoisting crane, clamping large vehicle walking track, and clamping jaw on the rail clamping device and track produce friction force, stop the cart motion, and friction force is the anti-wind brake ability.According to rail clamping device clamping process principle difference, rail clamping device can be divided into two kinds of versions, the clamping jaw of one type of rail clamping device is a flush type, directly contacts with track side surfaces, when hoisting crane moved, clamping jaw and track directly produced friction force; Another kind of type is a self-locking type rail clamping device, and the gripper clamp mouth is shaped as curved surface, when hoisting crane moves, the dependence of clamping jaw rotates with the friction force that track initially contacts generation, distance between two jaws is more and more littler, and the locking gripper rail produces friction brake force.
In theory, during rail clamping device work, should reach its design-calculated wind prevention braking ability, but the rail clamping device in actual the use, it is very big influenced by usage condition, and working stability is relatively poor, its subject matter:
1, rail clamping device is fixed on the machine of port, and the port machine is walked to the track deflection, causes rail clamping device to track also deflection, and clamping jaw and track side surfaces area of contact reduce, and friction brake force is descended.
2, some rail clamping device frame fixation are on the machine of port, clamping device moves along the horizontal groove of vertical track direction, to compensate cart along the track travel deflection, but because rail clamping device need be installed in more than the big Car Track, asymmetric up and down, adopt horizontal slot compensation rail clamping device with the deflection scarce capacity of large vehicle walking along track.
3, owing to adopt coil spring as the rail clamping device elastic element, its volume is bigger, and the mounting arrangements of whole rail clamping device part is difficulty; Spring axis needs the pilot bar guiding and supports the working service inconvenience simultaneously.
The utility model content
Technical problem to be solved in the utility model has provided a kind of portal crane steel spring rail clamping device, and the compact elastic force of this rail clamping device structure is big, and can compensate the rail clamping device beat that the large vehicle walking beat causes.
The utility model is achieved in that a kind of portal crane steel spring rail clamping device, comprise framework, bracing frame is housed in the framework, wheel is equipped with in the bottom of framework, bracing frame is installed a pair of clamping limb by bearing pin respectively along the axial two ends of track, and bearing pin is contained in the bottom of clamping limb; Link to each other with the oil cylinder strut bar along the clamping limb top of axis of an orbit to homonymy, the homonymy clamping limb is equipped with spring clamping plate between the top, the friction lining that matches with track is equipped with at jaw place, clamping limb bottom, between two oil cylinder strut bars hydraulic ram is housed, in the described bracing frame steel spring is housed, the steel spring upper support is on clamping limb and spacing by spring clamping plate, and steel spring is pressed to track by promoting clamping limb with friction lining.
Described steel spring adopts the slot form to be fixed on the bracing frame.
A pair of adapter shaft is equipped with in described bracing frame both sides, on the position that framework is inboard with adapter shaft matches otic placode is housed, and the diameter of described adapter shaft is less than the aperture of otic placode.
The hole of described otic placode is the inclination slotted hole.
The hole of described otic placode is the inclined ellipse hole.
The utility model adopts the steel spring of plug-in as elastic element, does not need the spring guiding mechanism, makes whole rail clamping device structure compactness, and elastic force is big, safeguards and changes conveniently; Make that simultaneously clamping limb jaw friction lining size can be bigger, increased the area of contact with track side surfaces, obtain big braking force.The diameter of the adapter shaft of framework and bracing frame is less than the aperture of otic placode, make it have certain oscillating quantity in vertical cart track alignment, the rail clamping device beat that compensation large vehicle walking beat causes, otic placode adopts and is in tilted layout simultaneously, inclination that can more effective correction clamping device.
