Abstract
The utility model discloses a span-variable gantry crane with chain hoist. which is rational in structure and convenient to use. According to the technical scheme, the span-variable gantry crane with chain hoist comprises main beam bodies, more than two cylindrical main beam bodies are nested, the section of each main beam body is shaped like an inverted Chinese character 'ao', a trolley is assembled on slide ways in the main beam bodies, and the lower part of the trolley is provided with an electric hoist. The idler wheels of the trolley are in a coaxial multi-wheel structure, and the radius difference between neighboring wheels is the height difference of the slide ways of two neighboring main beam bodies. The span-variable gantry crane with chain hoist is rational in structure, can be used in different usage occasions effectively, and is convenient for users to use.
Description
Technical field:
The utility model relates to transfer crane, particularly a kind of change span chain block transfer crane.
Background technology:
The girder of present chain block transfer crane generally all is to adopt i-beam structure, the length of girder immobilizes, if in indoor environment or when running into the less situation of usage space, be unfavorable for the use of chain block transfer crane, can not satisfy the user demand of user under different environments for use fully, have the situation of unreasonable structure.
Summary of the invention:
The purpose of this utility model is a kind of change span chain block transfer crane rational in infrastructure, easy to use of design.
The technical solution of the utility model is, a kind of change span chain block transfer crane, it comprises main beam, it is characterized in that: girder is plural tubular main beam suit, the cross section of main beam is for being inverted the structure of " recessed " font, slideway in main beam is equipped with roller vehicle, and the bottom of roller vehicle is equipped with electric block.The roller of described scooter is set to coaxial many wheel constructions, and adjacent wheel body semidiameter is the diff-H of the slideway of adjacent two main beams.
The utility model is rational in infrastructure, can be applied to different use occasions by actv., and is convenient for users to use.
Description of drawings:
Fig. 1 is structural representation of the present utility model, and Fig. 2 is the utility model main beam deployed condition scheme drawing
The specific embodiment:
Describe by reference to the accompanying drawings embodiment in detail, a kind of change span chain block transfer crane, it comprises main beam, girder of the present utility model is that plural main beam 2 is set in together, the cross section of main beam is for being inverted " recessed " character form structure, slideway 4 in main beam is equipped with roller vehicle 3, the bottom of scooter is equipped with electric block 5, the roller of the described roller vehicle of present embodiment is set to coaxial many wheel constructions, adjacent wheel body semidiameter is the diff-H of the slideway of adjacent two main beams, the slideway of roller in different main beams rolls and is difficult for producing vibration, slideway in adjacent main beam adopts the structure of arranged in dislocation, guarantee that main beam can carry out folding and unfolding, the folding and unfolding of main beam can adopt pulley 1 structure to assist, also can adopt the capstan winch structure to control, what present embodiment provided is that the pulley structure (in conjunction with shown in Figure 2) that main beam adopts carries out extension and contraction control, the two ends of each main beam are provided with fixed pulley, be fitted with steel rope on the fixed pulley, one end of steel rope is fixed on the turning cylinder of electrical motor, the other end is fixed on the casing of the main beam of volume minimum, direction of motor rotation is different, can control elongating or shortening of main beam, easy to use.The utility model suitable environment is wide, especially under indoor or narrow and small working environment, the utility model can be put into the operational zone under contraction state, again according to using needs to launch demand convenient for users to use.
Claims (2)
