Abstract
The utility model discloses a kind of anti-fall rail electric hoist trolleies, including bull headction, electric hoist trolley and the electric hoist on electric hoist trolley, the electric hoist trolley is equipped with two groups of idler wheels, two groups of idler wheels are pressed on the both sides of bull headction respectively, the electric hoist trolley section is u-shaped, a guider is respectively provided at the top of two vertical parts of the U-shaped, guider includes leading truck and directive wheel, and two directive wheels are pressed on respectively on two sides of bull headction vertical part.The utility model is simple in structure, a guider is respectively provided at the top of two vertical parts of electric hoist trolley, guider includes leading truck and directive wheel, two directive wheels are pressed on respectively on two sides of bull headction vertical part, so that the distance between two groups of idler wheels and bull headction vertical part on electric hoist trolley are stablized, electric hoist trolley sidesway on bull headction is avoided, so as to which electric hoist trolley be avoided to fall rail, it is ensured that the normal use of gantry crane.
Description
Technical field
The utility model is related to machinery fields, and in particular to a kind of anti-fall rail electric hoist trolley.
Background technology
Gantry crane is a kind of deformation of bridge crane, is called gantry crane.It is mainly used for outdoor goods yard, stock ground
The handling operation of goods, bulk goods.Gantry crane has the spies such as utilization of area rate is high, job area is big, adaptation is wide, versatile
Point is used widely in harbour goods yard.Its metal structure installs two legs as door-shaped frame under support main beam, can be with
It directly walks on the track on ground, girder both ends can have overhanging cantilever beam.Gantry crane is when in use, it is desirable that operator is hung down
Straight hoisting heavy, however some operators understand oblique pull weight to follow the line of least resistance, and electric hoist trolley is only the idler wheel pressure of both sides
In on bull headction, in oblique pull weight, electric hoist trolley can sidesway, a side wheel can be with rail frictions on bull headction.
And the vertical part of idler wheel and bull headction is more and more nearer, and the vertical part of the idler wheel of opposite side and bull headction is more and more remote, makes for a long time
With electric hoist trolley has the danger of pendant rail.
The content of the invention
The utility model provides a kind of anti-fall rail electric hoist trolley, solves prior art electric hoist trolley and there is pendant rail
The problem of dangerous.
The utility model is achieved through the following technical solutions：
A kind of anti-fall rail electric hoist trolley, including bull headction, electric hoist trolley and the electricity on electric hoist trolley
Cucurbit, the electric hoist trolley are equipped with two groups of idler wheels, and two groups of idler wheels are pressed on the both sides of bull headction respectively, and the electric hoist is small
Vehicle section is u-shaped, is respectively provided with a guider at the top of two vertical parts of the U-shaped, guider include leading truck with
Directive wheel, two directive wheels are pressed on respectively on two sides of bull headction vertical part.
The utility model is further improved scheme, and one end bottom of the leading truck is equipped with link slot, and directive wheel rotates
It is connected to the top of the leading truck other end.
The utility model is further improved scheme, and the link slot is connected in two vertical parts of electric hoist trolley U-shaped
Top, and be welded to connect with electric hoist trolley.
The utility model is further improved scheme, and the idler wheel on the electric hoist trolley is sequentially connected with driving device.
The utility model compared with prior art, has the following advantages that：
The utility model is simple in structure, and a guider is respectively provided at the top of two vertical parts of electric hoist trolley, is oriented to
Device includes leading truck and directive wheel, and two directive wheels are pressed on respectively on two sides of bull headction vertical part so that electric hoist
The distance between two groups of idler wheels and bull headction vertical part on trolley are stablized, and avoid electric hoist trolley sidesway on bull headction,
So as to which electric hoist trolley be avoided to fall rail, it is ensured that the normal use of gantry crane.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is the schematic diagram of electric hoist trolley.
Fig. 4 is the front view of Fig. 3.
Fig. 5 is the schematic diagram of guider.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of anti-fall rail electric hoist trolley, including bull headction 1, electric calabash
Reed trolley 2 and the electric hoist 3 on electric hoist trolley 2, the electric hoist trolley 2 are equipped with two groups of idler wheels 21, two groups of rollings
Wheel 21 is pressed on the both sides of bull headction 1 respectively, and 2 section of electric hoist trolley is u-shaped, the top of two vertical parts of the U-shaped
Portion is respectively provided with a guider, and guider includes leading truck 5 and directive wheel 4, and two directive wheels 4 are pressed on bull headction respectively
On two sides of 1 vertical part, one end bottom of the leading truck 5 is equipped with link slot 51, and directive wheel 4 is rotationally connected with leading truck 5
The top of the other end, the link slot 51 are connected in the top of two vertical parts of electric hoist trolley 2U fonts, and small with electric hoist
Vehicle 2 is welded to connect, and the idler wheel 21 on the electric hoist trolley 2 is sequentially connected with driving device.
It should be pointed out that for those skilled in the art, the utility model principle is not being departed from
On the premise of, several improvements and modifications can also be made, these improvements and modifications also should be regarded as the scope of protection of the utility model.
