The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model, for the unsettled problem of existing carrying weight device performance, provides a kind of stand alone type two hanger rail set a distance horizontal lifting chain driver trains.
As shown in Figures 1 to 4, the two hanger rail set a distance horizontal lifting chain driver trains of one stand alone type that the utility model embodiment provides, it is located in frame 1, comprise drive motor 2, change speed gear box and sprocket wheel, described drive motor 2 is located at frame 1 top, connect the first change speed gear box by coupler, described the first change speed gear box connects the second change speed gear box by transmission shaft 3, described the first change speed gear box connects the first sprocket wheel 11, described the first sprocket wheel 11 is provided with the first chain 4, described the first chain 4 bottoms are provided with the first tension wheel 5, described the second change speed gear box connects the second sprocket wheel 12, described the second sprocket wheel 12 is provided with the second chain 6, described the second chain 6 bottoms are provided with the second tension wheel 7, on described the first chain 4 and the second chain 6, be equipped with described hanger rail 8, between two described hanger rails 8, be provided with the objective table 9 of level.Described the first change speed gear box is all connected described calibrated disc 10 with the second change speed gear box, and described calibrated disc 10 is provided with zero point sensor 13.
This mechanism is according to the power of selected drive motor, the weight that draws high the intensity decision weight that carries of chain, in order to reduce manufacturing cost, drive motor 2 adopts common three phase alternating current motor, drive motor 2 drives the first change speed gear box by coupler, the first change speed gear box is by transmission shaft 3 second change speed gear box that is rigidly connected, and first, second change speed gear box drives respectively the sprocket wheel with first, second chain, and then reaches two synchronous rise/falls motions of chain.
Consistent for guaranteeing the move distance of 2 chains; on the output shaft of the first change speed gear box (initiatively), install calibrated disc additional; each motion cycle; approach the double wedge edge that zero point sensor 13 detects calibrated disc 10 and determine zero point; the second change speed gear box (driven) also installs same calibrated disc 10 and zero point sensor 13 additional simultaneously, and auxiliary detection, by electrical control; protection chain, avoids chain blocked or be pulled off.
The utility model mass motion process:
System is sent instruction; weight rise/fall fixed range (distance is determined by the design of calibrated disc calibration); the motion of motor chain drive-belt; the first calibrated disc detects ON zero point; judge whether ON at second calibrated disc zero point, if the second calibrated disc ON at zero point, setting in motion; if not ON, stop motion, plays the effect of protection chain and equipment.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
