Abstract
The invention discloses a hoisting device and method of an overhead frost prevention machine. The hoisting device is characterized in that a fixed pulley (5a) and a fixed pulley (5b) are fixed on a transverse rod of a suspension frame (3); the distance between the middle axes of the fixed pulley (5a) and a stand column (1) is equal to the distance between the middle axes of a lifting lug (9) and a cloud deck sleeve (12). A movable pulley of a pulley mechanism adopts a double pulley block so that a relatively large amount of labor is saved. The hoisting method comprises the following steps: a fixed bracket is mounted at the upper end of the stand column; the suspension frame is hollowly sleeved on the thin part at the upper end of the fixed bracket; the suspension frame can rotate freely for 360 degrees; when the frost prevention machine is hoisted to exceed the top of the stand column, the suspension frame is rotated to guarantee that the cloud deck sleeve is located right above the top of the stand column, so that the cloud deck sleeve and the stand column are prevented from being violently collided in the hoisting process. The hoisting process of the hoisting method is safe and reliable; the hoisting method is simple and convenient to operate and the installation and the maintenance of the overhead frost prevention machine are convenient.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.Should be understood that, the specific embodiment described herein only, for description and interpretation the present invention, is not construed as limiting the invention.
As shown in Figure 1, the invention provides a kind of hanging apparatus, this hanging apparatus comprises strut member and lifting part.Strut member comprises fixed support 2 and suspension 3, and the distance between the taper end center shaft of the upper cuff 13 of fixed support 2 and the center shaft of lower cuff 14 and fixed support 2 is 35cm.Lifting part comprises fixed pulley 5a, fixed pulley 5b, movable pulley 6 and rope 7, and wherein, fixed pulley 5a and fixed pulley 5b are fixed on suspension 3 by the mode of welding, and movable pulley 6 is hook type block pulley group.The hanger 9 of blower fan is arranged on the center of gravity line of assembly parts of blower fan, The Cloud Terrace, The Cloud Terrace sleeve, makes blower fan be lifted with operating attitude.Lifting object tea place overhead frost preventing machine mainly is comprised of the ladder etc. of climbing on column 1, blower fan 10, The Cloud Terrace 11, The Cloud Terrace sleeve 12 and column 1.
By such scheme, at first mounting and fixing bracket 2.Fixed support 2 is fixed on to the first half of frost preventing machine column 1 by upper cuff 13 and lower ferrule 14.
Secondly, the installation of assembly pulley.One end of rope 7 is fixed on to the suspension ring 4 on suspension 3, then through movable pulley 6, then passes fixed pulley 5b, 5a with this.
Again, suspension 3 is installed.Thin section by the vertical rod empty set of suspension 3 in fixed support 2 upper ends, can form the rotation of various angles between fixed support 2 and suspension 3, preferably, as shown in Figure 1, before the blower fan lifting, make suspension 3 back to column 1.
Then, on the ground The Cloud Terrace sleeve 12, The Cloud Terrace 11 and blower fan 10 are assembled, and with the frost preventing machine operating attitude, hang on the suspension hook of movable pulley 6 lower ends, by pulling rope 7, The Cloud Terrace 11 and blower fan 10 elevators to the bottom of The Cloud Terrace sleeve 12 is exceeded to column 1 apical position and stop, as shown in Figure 1.
Finally, climb staff on ladder by suspension 3 Rotate 180s ° by standing in column 1 top, because the distance between the taper end center shaft of the center shaft of the upper cuff 13 of fixed support 2 and lower cuff 14 and fixed support 2 is 35cm, having guaranteed has enough spaces between The Cloud Terrace 11 and suspension 3, has avoided the interference and collision between The Cloud Terrace 11 and suspension 3 in rotary course; Because the distance between fixed pulley 5a and column 1 center shaft equals the distance between hanger 9 and The Cloud Terrace sleeve 12 center shafts, guaranteed rotation suspension 3 can make The Cloud Terrace sleeve 12 be positioned at column 1 directly over, as shown in Figure 2, then, slowly pine moves back rope 7 and makes The Cloud Terrace sleeve 12 steadily be sleeved on the upper end of column 1, completes lifting.
It should be noted that, although the lifting of the overhead frost preventing machine in tea place of take in specification sheets is illustrated hanging apparatus of the present invention as example, but the purposes of this hanging apparatus is not limited to the situation described in specification sheets, in actual use, also can the lifting for other objects by above-mentioned hanging apparatus.
Below describe by reference to the accompanying drawings the preferred embodiment of the present invention in detail; but; the present invention is not limited to the detail in above-mentioned embodiment; in technical conceive scope of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can be combined by any suitable mode, for fear of unnecessary repetition, the present invention is to the explanation no longer separately of various possible array modes.
In addition, between various embodiment of the present invention, also can carry out combination in any, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
