Abstract

The utility model relating to a crane is a safety windproof buffer for crane. The utility model is characterized in that the safety windproof buffer for crane comprises a double I-rail arranged on a crane orbit and combined with the crane orbit into a friction pair. A truss formed by a front and a back bracket combined with an upper bracket is fixed on the double I-rail. A rubber body is fixed on the front end of the upper bracket on the truss. At least a damper unit contacting with the orbital plane of the crane orbit is inlayed in the double I-rail. The damper unit is formed by the connection of a damper base, a leaf spring arranged in the damper base, pretension bolts and pretension nuts arranged in the double I-rail. The utility model is characterized in simple structure, smooth braking, safety, reliability and wide application range. The safety windproof buffer for crane can make the crane run smoothly to consume energy and stop smoothly by brake resistance produced by damp.

Description

The windproof energy disperser of crane safety
Technical field
The utility model relates to hoisting crane, is the windproof energy disperser of a kind of crane safety.
Background technology
During hoisting crane prominent chance strong wind in service; prior art is to adopt devices such as shutting down folder rail, grappling to realize that hoisting crane is windproof; the complex structure of devices such as existing folder rail, grappling; poor reliability; still there is safety hazard; even hoisting crane is promoted by strong wind, the dead retaining of bump and causing is tumbled or is derailed.So that cause equipment and personal safety accident.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of and is installed on the crane track, produces braking force by damping hoisting crane jogging consumed energy is steadily shut down, and is simple in structure, the windproof energy disperser of the crane safety of dependable performance.
The technical scheme that solves its technical matters employing is: the windproof energy disperser of a kind of crane safety, its special character is: it comprises and being installed on the crane track 16, and two I-rails 15 with track 16 composition friction pairs, on two I-rails 15, be fixed with by preceding, after poppet 17,18 with the fixing truss of forming of upper bracket 2, upper bracket 2 front ends at truss are fixed with rubber bodies 1, be built-in with and contacted at least one the unit damper in crane track 16 rail planes at two I-rails 15, the unit damper is by damping seat 8, in damping seat 8, place leaf spring 9, give the jack panel 10 that gives that is provided with in tight bolt 5 and the two I-rails 15 and connect to form.Said unit damper or by damping block 7 gives the jack panel 10 that gives that is provided with in tight bolt 5 and the two I-rails 15 and connects to form.
The advantage applies of the windproof energy disperser of crane safety of the present utility model exists: 1, without the energy, do not need manual control, and simple in structure; 2, do not establish the basis in addition, be directly installed on the hoisting crane walking track, invest for a short time, dependable performance is convenient to the on-site installation adjustment; 3, adopt damping consumed energy mode, braking steadily, and is safe and reliable, to the hoisting crane zero damage; 4, adopt leaf spring or damping block, give the unit damper that jack panel connects to form that gives that is provided with in tight bolt and the two I-rails, one or more unit damper can be set according to the kinetic energy size of hoisting crane, can set up the size of dumping force by giving tight bolt; 5, applied widely, shut down applicable to the buffering that all types of open-air track crane safety are windproof.
The utility model is described in further detail below in conjunction with embodiment shown in the drawings.
Description of drawings
Fig. 1 is the windproof buffer structure scheme drawing of crane safety.
Fig. 2 is the schematic side view of Fig. 1.
Fig. 3 is a unit damper structure scheme drawing.
Fig. 4 is the schematic side view of Fig. 3.
The specific embodiment
With reference to Fig. 1-4, two I-rails 15 of the windproof energy disperser of crane safety place on the crane track 16, and two I-rail 15 usefulness bolts 14 connect, and the inboard inclined-plane of two I-rails 15 is close on the inclined-plane, both sides of crane track 16 and is formed the bilateral friction pair.On two I-rails 15, be fixed with the truss of fixedly forming by forward and backward support 17,18 and upper bracket 2 by bolt 6.Front frame 17 fixedly is made up of by bolt 13 and straight beam 12 preceding bearing 11.After poppet 18 fixedly is made up of by bolt 13 and cant beam 3 rear support 4.Upper bracket 2 front ends at truss are fixed with rubber bodies 1.Be built-in with and contacted unit, crane track 16 rail planes damper at two I-rails 15.The unit damper is placed leaf spring 9 by damping seat 8 in damping seat 8, give the jack panel 10 that gives that is provided with in tight bolt 5 and the two I-rails 15 and connect to form.Unit damper or by damping block 7 gives the jack panel 10 that gives that is provided with in tight bolt 5 and the two I-rails 15 and connects to form.Can one or more unit damper be set form one to multiple level energy disperser according to the magnitude of load of hoisting crane.Can choose the damper of band plate spring 9, or the damper of band damping block 7, or both combinations.Two I-rails 15 also can be installed on the track 16 of the hoisting crane that leaves truss one segment distance, on two I-rails 15, the unit damper be set and play auxiliary buffer action.
The utility model adopts four unit dampers to form multi-stage buffer, and wherein two is the unit damper of band plate spring 9, and two is the unit damper of damping block 7.Adopt the unit damper of a band plate spring 9 to form secondary buffer.The windproof energy disperser of crane safety of the present utility model places simultaneously on the two-orbit of hoisting crane and uses.
The working process of the windproof energy disperser of crane safety is; under the situation of hoisting crane prominent chance strong wind when work; buffer head on the hoisting crane is installed in walking track 16 ends with the certain speed collision and leaves on the rubber bodies 1 of the windproof energy disperser of certain coasting distance crane safety; by truss its transfer of energy is arrived two I-rails 15; under the effect of the friction drag of unit damper; hoisting crane is produced slowly slide, in the coasting distance scope of setting, hoisting crane is steadily shut down.
