Abstract
The utility model proposes a kind of crane, comprise the rectangle framework and the carrying platform that by Metallic rod, are formed, described rectangle framework comprises four columns that are parallel to each other, described carrying platform is set on described column by the sliding eye of surrounding, described carrying platform passes through chain traction, described chain is via the pulley gear on described column top, and be connected with motor in the below of described rectangle framework, thereby, by the traction of described motor, driven described carrying platform to move up and down along described column, after making workman be about to workpiece when ground to be well placed, again described carrying platform is risen to the height needing and carry out operation, difficulty and the degree of risk of operation have been reduced.
Description
Technical field
The utility model relates to mechanical field, refers to especially a kind of crane.
Background technology
Crane is stage construction, the indispensable operative installations of use etc., the comfort feature of its use and performance are directly connected to the complexity of site operation and the progress of construction, at present, what conventional crane adopted is fixing carrying platform, be that carrying platform is fixed on crane, can not move, during construction, need to be by workpiece by the devices such as hoisting crane hanging on carrying platform one by one, due to the liftoff height of carrying platform, therefore the complexity that this work becomes, and, high aerial, workpiece is reasonably put on carrying platform, and move position, all very difficult work, degree of risk is also very high, thereby, conventional crane in the use, also have and use inconvenience, the problems such as danger coefficient height.
Utility model content
The utility model proposes a kind of crane, solved the problem that the operation of prior art high and medium is inconvenient and uneasiness is congruent.
The technical solution of the utility model is achieved in that a kind of crane, comprise the rectangle framework and the carrying platform that by Metallic rod, are formed, described rectangle framework comprises four columns that are parallel to each other, described carrying platform is set on described column by the sliding eye of surrounding, described carrying platform passes through chain traction, described chain is via the pulley gear on described column top, and be connected with motor in the below of described rectangle framework, thereby, by the traction of described motor, driven described carrying platform to move up and down along described column.
Further, the number of described chain is 4, is connected to four jiaos of described carrying platform, and by described pulley gear, is not connected with motor, and 4 stressed more even, more steady up and down when traction.
Further, between described sliding eye and described column, be provided with roller, described in be fixed on described carrying platform, and with described column butt, described roller can improve the mild property while relatively moving.
Further, on described carrying platform, be also provided with for reinforcing the gripping mechanism with described column annexation, improve safety under static state.
Further, described gripping mechanism is be enclosed within the antislip ring on described column and screw bolt, described in screw bolt and described antislip ring is threaded connection, and described in screw bolt bottom contact with described column is separable.
The beneficial effects of the utility model are: the described crane the utility model proposes, by being set, described carrying platform can slide up and down along the column of described rectangle framework, thereby in use, workpiece first can be put on described carrying platform, and then by establishments such as described pulleys, described carrying platform is risen to the height needing, thereby reduced the difficulty of operation, also reduced the risk of operation.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of crane face of the utility model structural representation;
Fig. 2 is the column of crane shown in Fig. 1 and the structural representation of carrying platform contact position.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, a kind of crane, comprise the rectangle framework 1 and the carrying platform 2 that by Metallic rod, are formed, rectangle framework 1 comprises four columns that are parallel to each other 11, carrying platform 2 is set on column 11 by the sliding eye of surrounding, carrying platform 2 is by chain traction, and chain is via the pulley gear 3 on column top, and is connected with motor 6 in the below of rectangle framework 1.
Further, the number of chain is 4, is connected to four jiaos of carrying platform 2, and Tong Guo not be connected with motor 6 by pulley gear 3.
Further, between sliding eye and column 11, be provided with roller 4, be fixed on carrying platform 2, and with column 11 butts.
Further, on carrying platform 2, be also provided with for reinforcing the gripping mechanism 5 of same column 11 annexations.
Further, gripping mechanism 5 being for to be enclosed within the antislip ring 51 on column and to screw bolt 52, screw bolt 52 and be threaded connection with antislip ring 51, and the bottom that screws bolt 52 contacts with column 11 is separable.
Thereby, in use, by the draw of motor 6, through chain and pulley gear 3, driven carrying platform 2 to rise or decline again, roller 4 has promoted the flexible performance of relative sliding greatly, prevent the phenomenon stuck due to unbalance stress, workman can be about to workpiece and be placed on carrying platform 2 when ground, rises to aloft work after being well placed again, and has reduced difficulty and degree of risk that workpiece is put in high-altitude.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
