Description
Technical field
The present invention relates to hoisting crane, relate in particular to a kind of scalable guide piece that the path of motion to suspender for hoisting crane limits and the motion of suspender is led.
Background technology
The hoisting crane of prior art, carrys out hoisting heavy by suspender conventionally, and suspender is connected with dolly by steel rope, suspender is in lifting up and down or during with dolly parallel motion, usually swing and rock, affecting the safety of suspender and weight, making suspender cannot be parked in quickly and accurately assigned address.
Therefore, the guide piece that needs a kind of path of motion to suspender to limit and the motion of suspender is led, to overcome the above problems.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of scalable guide piece, to solve suspender in prior art, usually swing and rock, affecting the safety of suspender and weight, making suspender cannot be parked in quickly and accurately the technical matters of assigned address.
Another object of the present invention is to provide a kind of the present invention of having hoisting crane of scalable guide piece.
The present invention is achieved through the following technical solutions:
A kind of scalable guide piece, for hoisting crane, it is characterized in that, described scalable guide piece comprises between the vehicle frame bottom surface and the suspender of described hoisting crane of a plurality of dollies that are arranged on described hoisting crane, and be evenly arranged in around the suspender of described hoisting crane the scalable assembly that can stretch up and down under the drive of described sling lifting.
Hoisting crane of the present invention, has scalable guide piece of the present invention.
Beneficial effect of the present invention is, scalable guide piece of the present invention, make full use of the telescopic nature of four connecting rod assemblies, both sides in two vertical direction of suspender surrounding arrange respectively each two cover, are total to quadruplet four connecting rod assemblies, can move up and down with suspender, limited again the swing of suspender any direction in horizontal surface, simple in structure, be easy to processing and fabricating, installation and repairing.
Accompanying drawing explanation
Fig. 1 is the hoisting crane of the embodiment of the present invention and the schematic diagram of scalable guide piece thereof;
Fig. 2 is the schematic diagram of four connecting rod assemblies of the scalable guide piece of the embodiment of the present invention.
The specific embodiment
The exemplary embodiments that embodies feature & benefits of the present invention will describe in detail in the following description.Be understood that the present invention can have various variations on different embodiment, it neither departs from the scope of the present invention, and explanation wherein and accompanying drawing be when the use that explain in itself, but not in order to limit the present invention.
The scalable guide piece of the embodiment of the present invention can be used in the hoisting crane of the embodiment of the present invention, be applicable to all need to the path of motion of suspender limit and hoisting crane that its motion is led in.
Below specifically introduce the scalable guide piece of the embodiment of the present invention.
As shown in Figure 1, the hoisting crane of the embodiment of the present invention has dolly 11 and suspender 12, also comprises mechanism that other is necessary and structure etc.
Suspender 12 is conventional suspender, generally includes pulley, suspension hook and framing member etc., and draft arm 121 is four rod members, in suspender 12 surroundings, is uniformly distributed, and its one end is fixedly connected on the framing member 122 of suspender 12.
The scalable guide piece of the embodiment of the present invention is arranged between dolly 11 bottom surfaces and suspender 12 of hoisting crane 1, scalable guide piece is preferably comprised of four group of four connecting rod assembly 2, the bottom of four group of four connecting rod assembly 2 is distributed on suspender 12 surroundings, and top is fixedly connected on the bottom surface of dolly 11.But the present invention is not as limit.It is four that the quantity that forms four connecting rod assemblies 2 of scalable guide piece of the present invention is also not limited to, and can be three or five etc., determines as the case may be.
In the present embodiment, each four connecting rod assembly 2 all one flexible in perpendicular to the plane of dolly bottom surface, this plane can be described as the flexible plane of this four connecting rod assembly 2.Adjacent two four connecting rod ancestrals' 2 flexible plane is mutually vertical, and therefore, the flexible plane of four four connecting rod assemblies 2 of the scalable guide piece of the embodiment of the present invention, surrounds a four-prism jointly.Scalable guide piece of the present invention, if four connecting rod assemblies are three or five, can surround a regular triangular prism or positive pentagonal prism.Each above-mentioned flexible plane, all perpendicular to the vehicle frame bottom surface of dolly 11.
As shown in Figure 2, each four connecting rod assembly 2 comprises upper articulation point 21, lower hinge point 22, quarter butt 23, quarter butt 24, stock 25, stock 26 and pipe link 27 etc.
Wherein, upper articulation point 21 is fixedly connected on the bottom of pipe link 27, and the top of pipe link 27 is fixed on the vehicle frame bottom surface of dolly 11.Or upper articulation point 21 can directly be fixed on the vehicle frame bottom surface of dolly 11.22 of lower hinge points are connected on four draft arms 121 that suspender 12 stretches out at four direction.Therefore, four group of four connecting rod assembly 2 is evenly arranged in suspender 12 surroundings.
Two groups of quarter butts 23, quarter butts 24 are articulated with respectively upper articulation point 21, lower hinge point 22, and as shown in Figure 2, many group leaders bar 25, stock 26 are hinged at mid point and two ends, and the length of stock is the twice of quarter butt length.The two ends up and down of the assembly that stock 25, stock 26 form are hinged with upper and lower two groups of quarter butts 23, quarter butt 24 respectively, have finally just formed one group of four connecting rod assembly 2.
Like this, suspender 12 is when lifting mechanism, steel rope move up and down under driving, can drive the lower hinge point 22 of four connecting rod assemblies 2 to move up and down by draft arm 121, due to the telescopic nature of four connecting rod assemblies 2, can guarantee that lower hinge point 22 can move up and down with suspender 12.Simultaneously because four connecting rod assemblies 2 are suspender 12 pining down of four direction around; suspender 12 swing is in the horizontal direction restricted; both so just realized and can move up and down with suspender 12; can limit the swing of suspender 12 horizontal direction in any horizontal surface again, effectively to protect the safety of suspender 12 and weight and guarantee the accurate location of suspender and stop rapidly.
Also being not limited to of scalable assembly that forms scalable guide piece of the present invention is four connecting rod assemblies, can be also other forms of scalable assembly, and stretch in same plane at scalable assembly.
Technical scheme of the present invention is disclosed as above by preferred embodiment.Those skilled in the art should recognize in the situation that do not depart from change and the retouching that scope and spirit of the present invention that the appended claim of the present invention discloses are done, within all belonging to the protection domain of claim of the present invention.
