Description
Technical field
The present invention relates to a kind of method and device of farmstead equipment upper air installing, be specially adapted to lifting and the maintenance of tea fruit garden frost preventing machine The Cloud Terrace and fan part.
Background technology
Early spring, the cold spell in later spring Spring frost caused cataphoretic failure to agricultural crops.The outer main mechanization frost prevention equipment of using of Present Domestic is under the inversion condition that frost is arranged, by flow perturbation near-earth air layer, nearly the top than the warm air forced convection, blow to the canopy of tea fruit tree, improving its temperature, thereby reach the purpose of frost prevention.U.S. patent of invention US5244346, US4753034 and US4838761, Japanese patent of invention JP2007000096, JP2000050749 and JP10113076 all disclose the frost prevention method and apparatus of this type of principle of work; Chinese invention patent Zl200810124434.7 also discloses use control method and the device of above principle of work device.The basic comprising of such frost prevention equipment is comprised of climb ladder and the control system etc. that are installed on the higher column (3 ~ 10 meters) in the tea fruit garden, the blower fan that is positioned at the column top and The Cloud Terrace, the column.
Through investigation, in production practice, existing mounting means generally has following several such device in the field: (1) is installed on column or steel tower in the field soil first, then set up specially platform (such as scaffold) at column or steel tower next door, stepped on to table top assembling The Cloud Terrace and blower fan by installation personnel at last.(2) first column or steel tower are installed in the field soil, then use jacking equipment, blower fan and The Cloud Terrace and installation personnel are risen to column or top of tower, assemble.(3) on the ground blower fan and The Cloud Terrace are assembled to column or tower one end first, re-use heavy mechanical equipment (such as crane), the whole series equipment is lifted into the desired location.Rear two kinds of installation methods are suitable for using in the smooth open orchard.But above installation method complicated operation needs to use complicated facility or equipment, and cost is higher, also has certain safety problem, uses to be restricted in Hills tea fruit garden with a varied topography.Therefore, existing above-mentioned I﹠M method makes agricultural overhead frost preventing machine be difficult to further be applied.
Know through document and patent retrieval, can utilize the implementation structures such as track, pulley or silk axle simply to lift function.U.S. patent of invention US6522025 discloses and a kind of blower fan has been installed to the method and apparatus at top from tower bottom, also can blower fan be unloaded from top of tower and deliver to the bottom.It arranges two tracks from top to bottom in a side of tower, and coaster of operation individual drive has the fixedly platform of blower fan at coaster on it.The method has been utilized tower body structure, and is simple to operate, but elevator part-structure relative complex, cost is higher.Chinese utility model patent ZL201120134757.1 discloses a kind of mast-up, is comprised of bracing frame, support mechanism and engine installation etc., can realize the at the uniform velocity steadily lifting of weight.Chinese utility model patent ZL201120440748.5 discloses a kind of hanging apparatus of bearing, be comprised of stay bearing plate, jack, flange, rope and pulley etc., but exactly ground keeps bearing and bearing seat dead in line.Finishing of rear two kinds of device lifting functions all needs to have the fixed support surfaces of eminence, thereby is unsuitable for the lifting of agricultural overhead frost preventing machine.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of hanging method and device that is suitable for agricultural overhead frost preventing machine The Cloud Terrace and blower fan, overcome that hanging apparatus complex structure in the prior art, operation inconvenience, cost are high, poor stability, in defectives such as the limited difficult popularizations of Hills with a varied topography.
For solving the problems of the technologies described above, the technical solution used in the present invention is: utilize height and the structure of frost preventing machine column, at described frost preventing machine column installing fixed support and suspension, realize the support of assembly pulley, thereby utilize assembly pulley to lift.This hanging method is further comprising the steps of:
(1) by the pulling rope, will hang on frost preventing machine The Cloud Terrace and blower fan on the suspension hook of movable pulley lower end with operating attitude, be transported to The Cloud Terrace sleeve bottom and exceed frost preventing machine column topmost position;
(2) by pulling The Cloud Terrace, the coupling bush of its lower end is positioned at directly over the frost preventing machine column, slowly pine moves back rope and makes the The Cloud Terrace sleeve steadily be inserted in the frost preventing machine column, namely finishes lifting.
In order to realize above-mentioned hanging method, the invention also discloses a kind of agricultural overhead frost preventing machine hanging apparatus, comprise fixed pulley, movable pulley, rope, characterized by further comprising cuff at the fixed support of the frost preventing machine column first half and the suspension of empty set thin section on fixed support; Described suspension can freely rotate around described fixed support; The cross bar of described suspension should be higher than described frost preventing machine column top, and it is apart from least 0.3 meter of the height that exceeds suspended object; Described fixed pulley is fixed on the far-end (away from suspension vertical rod one side) of described suspension cross bar; Described rope one end is fixed on the near-end of described suspension cross bar, successively passes described movable pulley and fixed pulley, and the described rope other end dangles naturally to ground.
The beneficial effect that the present invention has is: use the simple structures such as fixed support, suspension, assembly pulley, finish the lifting of agricultural overhead frost preventing machine The Cloud Terrace and blower fan, easy and simple to handle, general two people can realize the lifting of agricultural overhead frost preventing machine The Cloud Terrace and blower fan fast, and need not other power, thereby cost is lower; Be particularly suitable in slope, Hills tea fruit garden and less operational space, carrying out the I﹠M of this type of frost preventing machine; Large scale application for promoting this type of frost preventing machine has great importance.
