Abstract
The utility model relates to a hoist cross track locking device which belongs to the hoisting apparatus field. The hoist cross track locking device is characterized in that the end portion of a fixed leg which can be inserted in a fixed jacket and is fixedly arranged on the side end of a main beam is hinged with an intermediate connecting rod; one end of the intermediate connecting rod is hinged with one end of a movable block in a wedge shape; the movable block in a wedge shape is driven by a rotating shaft fixedly arranged on the main beam to realize the oscillation of both ends of the movable block. The structure of the hoist cross track locking device is simple, and the connection and the fixed installation of the main beam and a fixed beam are realized by adopting a simple lever principle; the hoist cross track locking device is safe and reliable, which is not only suitable for a single-beam suspension hoist, but also suitable for the cross track of double beams or the cross track of a multi-node main beam.
Description
Technical field
The utility model belongs to the weight-lifting equipment field, and especially a kind of hoisting crane is crossed the rail blocking device.
Background technology
The girder of common hoisting crane all is that its two ends are installed in the horizontal walking that realizes cart on the bracket, and dolly (electric block) lifting starting parcel is vertically walked on girder.But excessive in the factory building span, when perhaps not allowing to advance cart on Diao Zhuan the cargo location space, just need dolly to carry out the rail lifting.The existing rail mode of crossing generally is to realize installing of girder and fixed beam (crossing beam-and-rail) at the side of girder by adopting motor-driven rack for transmission mode, the bad grasp of accuracy of alignment, structure are comparatively complicated, and it is not firm to install, throw off easily, the hidden danger that dolly falls down might take place.And adopting import to cross the rail hoisting crane, its price is high.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, and connection installs firm hoisting crane and crosses the rail blocking device.
The utility model solves its technical matters and takes following technical scheme to realize:
Hoisting crane is crossed the rail blocking device, be packed on the girder of hoisting crane, it is characterized in that: the hinged middle brace rod in the end of the fixed leg in the be inserted into fixed cover that on the girder side, installs, one end of the hinged inclined wedge-shaped movable block of this middle brace rod one end, this inclined wedge-shaped movable block by the driving that is packed in the rotating shaft on the girder to realize the swing at its two ends.
And the other end of inclined wedge-shaped movable block is inlaid in one and vertically is inserted in the groove of the limiting stopper upper end in the girder, and the rail of crossing that the lower end long enough of this limiting stopper can block dolly moves.
And, what be packed in that the rotation of the rotating shaft on the girder passes through is the realization that affects that its end installs a fork, the two ends of fork are equipped with pulling rope, be shaped on an elasticity radius stay at the middle part of fork, the end of this elasticity radius stay is fixed with spring, and the other end of this spring is packed on the spring plate that is solidly installed with girder.
And fixed leg is realized guiding by the guide pin bushing that is packed on the girder.
Advantage of the present utility model and good effect are:
1. simple in structure.Adopt simple lever principle, can realize being connected and installing of girder and fixed beam, integral structure is simple, installs easily, and cost is low.
2. safety is secure.Be provided with limiting stopper, avoided dolly crossing the hidden danger that falls down behind the rail effectively, guaranteed the safety of people's life and property.
3. applied widely.Not only be applicable to the single-beam overhang crane, also go for the rail of crossing of twin beams or multinode girder,

Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the enlarged front view of the rail device of Fig. 1;
Fig. 4 is the birds-eye view of Fig. 4;

The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
This hoisting crane is crossed the rail blocking device, and its rail device 4 can be installed on the girder 2 of single-beam overhang crane, also can be installed on the girder of double girder crane and other hoisting cranes.Hoisting crane generally comprises cart 1, girder, on girder the vertical dolly 3 of operation, the side that closes on fixed beam that rail device is packed in girder.In the ordinary course of things, crossing being connected and fixed of rail adopts general-duty to be inserted into fixed cover 12 forms that install on the fixed beam 5 at the fixed leg 11 that installs on the girder.Innovation part of the present utility model is: the hinged middle brace rod 16 in the end of this fixed leg, this fixed leg is by being packed in the guiding of the guide pin bushing 10 realization fixed legs on the girder.One end of the hinged inclined wedge-shaped movable block 15 of the other end of middle brace rod, this inclined wedge-shaped movable block by the driving that is packed in the rotating shaft 17 on the girder to realize the swing at its two ends, what the rotation of this rotating shaft was passed through is the realization that affects that its end installs a fork 8, the two ends of this fork all are equipped with pulling rope 13, be shaped on an elasticity radius stay at the middle part of fork, the end of this elasticity radius stay is fixed with spring 7, and the other end of this spring is packed on the spring plate 9 that is solidly installed with girder.Like this, by the tractive pulling rope, can realize the swing of inclined wedge-shaped movable block, make the inclined wedge-shaped movable block move to another fixed point that resets by this spring from the fixed point that resets, thereby the tractive middle brace rod drives the parallel motion of fixed leg, realizes being connected and fixed or throwing off of girder and fixed beam.In addition, this rotating shaft also can realize that the electronic rail of crossing installs by motor-driven mode.
Rail device on girder is packed on the backing plate 14 that is solidly installed by screw (among the figure not label) with girder.
In order to prevent that unexpected the cross rail of dolly before crossing rail to connect preparation from causing the hidden danger that drops, be provided with safety gear: the other end of inclined wedge-shaped movable block is inlaid in one and vertically is inserted in the groove of limiting stopper 6 upper ends in the girder, and the lower end long enough of this limiting stopper moves with the rail of crossing that blocks dolly.So, when the swing of inclined wedge-shaped movable block and driving fixed leg insertion fixed cover, limiting stopper can promote to remove dolly and cross the qualification of rail (this moment, fixed beam was connected with girder); Limiting stopper decline can be set dolly and cross the qualification of rail (this moment, fixed beam and girder were thrown off), thereby realizes crossing safely rail.
