The utility model comprises a casing arranged at the upper part of fixed guide rails, a centrifugal trigger mechanism, a linkage mechanism, and a locking mechanism. The utility model has the advantages that friction wheels can be made to keep close contact with the guide rails, in order that as the utility model falls, the timely triggering and braking can be realized, and simultaneously the misoperation can be prevented; the utility model comprises a braking mechanism having two eccentric braking wheels, and thus the braking effect is good, the bearing capacity is high, and the bearing weight of one side of the guide rails is over three tons; the utility model has short braking stroke, and can be efficiently braked in 20 centimeters. The utility model also has the advantages of 100% sensitivity, simple structure, easy manufacture, and low cost, and is suitable for various places needing weight lifting, such as buildings, mines, tunnels, etc.
Description
The utility model belongs to guide tracked lift installation falling-proof safety device.
At present, in construction trade, coal mine excavation industry and constructing tunnel, all there is problem with weight or Lifting and lowering for scaffold, particularly in building industry, attached lifting scaffold is widely used, but the serious accident that this scaffold usually falls in construction, therefore, how to prevent that falling of allied equipment from just becoming the problem that current urgent need solves.That the structure of adhering lifting climbing frame comprises substantially is guide tracked, main cover posture, overhanging type and hang pull-type, wherein main cover posture, overhanging type and to hang the fall arrest of pull-type structure wayward.The anti-fall device that on integral electric lifting scaffold, uses, main degree of tightness control brake by hoisting cable, or, mainly comprise supporter, trigger mechanism, link gear and catch gear with Electromagnetic bolt is joined hole and structure at regular intervals or triggered with electromagnetic induction on guide rail wedge-type structure.These install most complex structure, trigger poor performance, or are prone to maloperation, and its coupling mechanism force is little, and it is long effectively to lock braking distance.
The utility model purpose provide a kind of simple in structure trigger sensitive and do not have the short coupling mechanism force of maloperation braking distance big adhere to guide tracked lift installation fall arrest safety.
The utility model comprises the housing that is installed in fixed guide top, centrifugal trigger mechanism, link gear and catch gear are formed, it is characterized in that centrifugal trigger mechanism is by the sedimentator axle, sliding type elasticity sedimentator pedestal and support are installed in housing bottom, sedimentator axle one end fixed installation friction wheel, its other end is installed centrifugal-disc, the outer centrifugal box of movable set of centrifugal-disc, install in the centrifugal box 3 with centrifugal-disc on centrifugal triggering pin that cooperates installing, it is hinged that gram in the outer and link gear of centrifugal box collapses an end of switch connecting rod, the other end of connecting rod is hinged with the end that gram collapses switch activated bar, the actuating lever other end and housing are hinged, gram on the actuating lever collapse with catch gear in brake wheel on anti-rotation groove cooperate, catch gear comprises two brake eccentrics that are installed on the housing, two eccentric wheel are hinged with an end of big connecting rod respectively, a return is installed on one of them brake eccentric is removed handle, this is removed an extension spring is installed between handle and the case top, and movable guiding rail is eccentric from two brakings
Pass in the middle of the wheel.
The utility model embodiment accompanying drawings is as follows:
Fig. 1. fall arrest safety structure cutaway view,
Fig. 2. A-A echelon sectional view among Fig. 1,
Fig. 3. B-B cutaway view among Fig. 1.
As scheme institute's formula, this adheres to guide tracked lift installation fall arrest safety, comprise the housing 1 that is installed in fixed guide top, centrifugal trigger mechanism, link gear and catch gear are formed, it is characterized in that centrifugal trigger mechanism is by sedimentator axle 7, sliding type elasticity sedimentator pedestal 20 and support 2 are installed in housing bottom, a jackscrew 22 is installed on housing, the end of jackscrew contacts with sliding type elasticity sedimentator pedestal 20, on the jackscrew between sliding type elasticity sedimentator pedestal and the housing, be set with a stage clip 21 that can make friction wheel 5 and movable guiding rail 19 tight crimping, sedimentator axle one end fixed installation friction wheel 5, its other end is installed centrifugal-disc 14, the outer centrifugal box 4 of movable set of centrifugal-disc, install in the centrifugal box 3 with centrifugal-disc on centrifugal 15 triggering pin 3 that cooperates installing, a return handle 16 is installed simultaneously, be equipped with two fan-shaped centrifugal 15 on the centrifugal-disc, centrifugal one end and centrifugal-disc are hinged, between the centrifugal other end and another the centrifugal pin jointed end extension spring 17 are installed.It is hinged that gram in the outer and link gear of centrifugal box collapses an end of switch connecting rod 6, the other end of connecting rod is hinged with the end that gram collapses switch activated bar 8, the actuating lever other end and housing are hinged, gram on the actuating lever collapse with catch gear in brake wheel 11 on anti-rotation groove cooperate, catch gear comprises by pivot shaft 18 and is installed in two brake eccentrics 10 on the housing, 11, two eccentric wheel are hinged with an end of big connecting rod 9 respectively, a return is installed on one of them brake eccentric 11 to be removed 13, this is removed an extension spring 12 is installed between handle and the case top, and movable guiding rail 19 passes in the middle of two brake eccentrics.
The engagement edge of brake eccentric is provided with one group of sawtooth, this sawtooth and movable guiding rail promptly can be that straight line contacts also can be the camber line contact, or right angle contact, to adapt to the needs of difformity movable guiding rail respectively, as circular, square, rectangle, channel-section steel, I-beam section, H shaped steel, railway steel etc.
When lift installation and guide rail falling speed surpass operating mode speed, centrifugal centnifugal force is greater than the pulling force of extension spring, centrifugal box work, centrifugal drives centrifugal box by the triggering pin and rotates, the switch connecting rod drives actuating lever and gram on the actuating lever is collapsed the anti-rotation groove from brake wheel throw off, brake wheel rotates under the extension spring effect and with the movable guiding rail wedging, can moment from being about to the lift installation braking and locking, play the fall arrest purpose.
The utility model advantage: 1) owing at the sedimentator axle jackscrew stage clip is housed, can make friction pulley with Movable guiding rail keeps close contact, to guarantee effective triggering, an extension spring is housed simultaneously between centrifugal-block, should Extension spring can be determined the pulling force size according to whereabouts operating mode speed, to guarantee in time triggering braking when falling simultaneously again Maloperation can not appear; 2) owing to adopt two brake eccentrics to add the arrestment mechanism of connecting rod, make its braking effect Fruit is good, and bearing capacity is big, and one-sided guide rail bearing load is more than 3 tons; 3) trigger sensitivity height, braking distance Short, can be at 20CM with interior effective brake, (namely rotating sixth effective brake in week at centrifuge box), system Moving sensitivity is up to 100%; 4) simple in structure, braking is easy, and cost is low, is convenient to promote, and is applicable to and builds Build, mine, tunnel etc. need all occasions with the weight lifting.
