Description

A kind of hook that changes
Technical field
The utility model belongs to lifting transportation technology field, is specifically related to a kind of hook that changes.
Background technology
Hoisting transportation equipment is widely used in every field, for specific crane layout and limit travel, by situations such as the transportation route of handling article, environment spaces, often needs the multi-section crane jointly to cooperate, and " relay " finishes handling work.Usually when changing crane, at first need and to be put on the ground by article hoisting, make to be connected to by the suspension hook of the suspender on the article hoisting and current crane to break away from, the suspension hook of next crane is connected by the suspender of article hoisting, thereby will be hung the next position by article hoisting.But, when can not put down by self structure restriction midway or environment space does not allow it to put down, namely must be finished when changing the hook operation at the lifting state by the handling article, existing suspender can't satisfy operating needs.
The utility model content
For the defective that exists in the prior art, the purpose of this utility model provides a kind ofly can finish the hook that changes that changes hook operation at the lifting state, and it is simple in structure, connects reliable, easy to operate.
For reaching above purpose, the technical solution adopted in the utility model is: a kind of hook that changes, and comprise and change hook plate, link span and hook with safety tong, the bottom of changing hook plate is connected to the top of link span pivotly, and hook with safety tong is connected to the bottom of link span; The top of changing hook plate is provided with two and changes dog hole.
Further, change the bottom of hook plate and be located at out in the groove on link span top, and link together by the top of bearing pin and link span, and the afterbody of bearing pin is provided with spring cotter; It is pivoted around bearing pin to change hook plate.
Further, change the equilateral triangle that hook plate is handstand, its three curved structures in bight, two are changed dog hole and lay respectively at the place, two bights that changes the hook plate upper end; Change the groove that bight, hook plate lower end is arranged in link span top.
Further, the top of hook with safety tong is connected with screw rod, and the screw rod of hook with safety tong screws in the set tapped bore in link span bottom and by being enclosed within two fastening nuts on the screw rod.
Further again, be provided with the spring shim that is enclosed within on the screw rod between link span and the nut that is adjacent.
The utility model provides changes hook, by set up at existing suspender with two change dog hole and can rotate within the specific limits change hook plate, can conveniently realize being interrupted changing hook by the nothing of article hoisting, effectively solving is needed to change handling appliance by article hoisting midway and can not directly land the problem of changing, and has improved work efficiency; And it is simple in structure that this changes hook, connects reliable, easy to operate.
Description of drawings
Fig. 1 is a kind of structural representation that changes hook that the utility model provides, and wherein the above part of link span adopts the form of longitudinal diagram to show;
Fig. 2 is the right elevation of the first half among Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
As shown in Figure 1, a kind of hook that changes provided by the utility model comprises and changes hook plate 1, link span 4 and hook with safety tong 7 that the bottom of changing hook plate 1 is connected to the top of link span 4 pivotly, and hook with safety tong 7 is connected to the bottom of link span 4; As shown in Figure 2, the top of changing hook plate 1 is provided with two and changes dog hole 1-1.
In a kind of specific embodiment, groove is offered on the top of link span 4, and the bottom of changing hook plate 1 is located in this groove, changes the bottom of hook plate 1 and the top of link span 4 and links together by the bearing pin 2 that runs through wherein, and the afterbody of bearing pin 2 is provided with spring cotter 3, moves axially with restriction bearing pin 2; And changing hook plate 1 can be pivoted within the specific limits centered by bearing pin 2.Change any suitable shape of adopting of hook plate 1, only otherwise hook is changed in impact that operation gets final product.
In the embodiment shown in fig. 1, change the equilateral triangle that hook plate 1 is handstand, its three curved structures in bight, two are changed dog hole 1-1 and lay respectively at the place, two bights that changes hook plate 1 upper end; Change the groove that bight, hook plate 1 lower end is arranged in link span 4 tops.
In addition, the top of hook with safety tong 7 is connected with screw rod 8, and the screw rod of hook with safety tong 78 screws in the set tapped bore 9 in link spans 7 bottoms and be fastening by two nut 6-1,6-2 being enclosed within on the screw rod 8.Further, be provided with the spring shim 5 that is enclosed within on the screw rod 8 between link span 4 and the nut 6-1 that is adjacent, two nut 6-1,6-2 on this spring shim 5 and the screw rod 8 play the purpose that prevents that hook with safety tong 7 from getting loose jointly.
Use that the utility model provides change hook to be in the lifting state changed the hook operation by article hoisting the time, it is as follows that it changes the hook process:
The first step: under the initial condition, the suspension hook A of crane A with change hook on change of hook plate 1 and change dog hole 1-1 and be connected, be connected on the hook with safety tong 7 that changes hook by article hoisting, be in the lifting state;
Second step: the suspension hook B that makes crane B with change hook plate 1 another change dog hole 1-1 and be connected, the suspension hook of two cranes all with change hook plate 1 and be connected;
The 3rd step: the suspension hook B of crane B is hoisted, change hook plate 1 and rotate, treat that crane B bears fully originally to change hook and during by the weight of article hoisting, suspension hook A is lax;
The 4th step: the suspension hook A that makes crane A with change hook plate 1 and separate, crane B is in the residing initial condition of crane A in the first step, changes hook work and finishes.
Structure described in the utility model is not limited to the embodiment described in the specific embodiment, and those skilled in the art draw other embodiment according to the technical solution of the utility model, belong to equally technology innovation scope of the present utility model.
