Abstract
The utility model relates to a prop drawing hoister for mine or construction hoisting, which is composed of a roller, a motor, a speed reducer and a braking device. The utility model is characterized in that the speed reducer arranged in the roller is composed of two outer gears in eccentric arrangement, an inner gear, a middle floating disc, an output floating disc, an input shaft and an output shaft, and therefore, the utility model has high transmission efficiency. The utility model utilizes a block type brake to brake the input shaft so as to have the advantage of reliable braking effect, and the speed reducer is arranged in the roller so that the utility model has the advantages of compact structure, light weight and small ground occupation.
Description
The utility model relates to a kind of drawing hoist, exactly is a kind of mining or building lifting drawing hoist.
Drawing hoist is mainly used in traction, drag weight or at the driving surface withdrawing prop.At present JH series is adopted in the colliery more, and it develops in five, the sixties, mainly contains specifications such as 3 tons, 5 tons, 8 tons, 14 tons.Find that in use it has many defectives:
(1) JH-5 type drawing hoist adopts three grades of transmissions.Be the tune-up center height, the first order is the external gear transmission of transmitting ratio i=1; The second stage is the worm and gear transmission; The third stage is that external gear drives the big external gear transmission that is fixed on the cylinder by idle pulley.Therefore, loosely organized, heaviness, floor area is big.
(2) because the middle one-level of three grades of transmissions of JH-5 type drawing hoist is the worm and gear transmission, thereby its transmission net effciency is lower than 50%, the specific energy consumption height.
(3) propulsion source of JH-5 type drawing hoist is the fire proof motor of a 7.5kw.The price of this kind motor is about about 2500 yuan, and needs relief cable and corresponding electrical controller, so economy is relatively poor, especially uses in the down-hole, and safety is also relatively poor.
In decades, JH series drawing hoist was also carried out many improvement, but these improvement are to carry out on the basis that keeps original propulsion source and type of belt drive mostly, it is not very big improving.
The purpose of this utility model provides and a kind ofly overcomes existing drawing hoist defective, and the efficient height, and cost is low, safe and reliable drawing hoist.
The purpose of this utility model is realized by following technical scheme.
The utility model is made up of cylinder, motor, retarder and brake equipment, it is characterized in that:
A, place the interior retarder of cylinder to comprise the external gear of two arranged off-centre, inner gear, middle floating disc, the output floating disc, input shaft and output shaft, the external gear of two arranged off-centre is housed on the input shaft, floating disc in the middle of the left side external gear is connected by a pair of set pin, middle floating disc connects the right side external gear by pair of pin, the right side external gear connects the output floating disc by pair of pin, the output floating disc connects output shaft by pair of pin, inner gear joins cylinder by flat key, cylinder is supported on input shaft and output shaft respectively by the diaxon bearing, the output shaft of motor connects input shaft by coupler, output shaft is fixed in the right supporting, input shaft is supported by a left side, the output shaft supporting, a left side, right supporting is fixed on the base;
B, described brake equipment are made up of pump, spring, hydraulic actuating cylinder, block brake lock and change-over valve, and coupler places in the block brake lock.
Motor adopts HM Hydraulic Motor or emulsion motor or gear motor or piston motor, and it is medium that motor adopts hydraulic oil or oil emulsion.
The utility model has the advantages that compact conformation, volume is little, and is in light weight, low cost of manufacture, and the driving efficiency height, load-carrying capacity is big, installation, easy to use, safe and reliable.
Fig. 1 is the utility model structural representation.
Fig. 2 is the brake equipment scheme drawing.
By the following examples, in conjunction with the accompanying drawings, the utility model is done to describe further.
Embodiment 1:
(referring to Fig. 1,2) retarder 3 places in the cylinder 1, retarder 3 comprises the external gear 5 of two arranged off-centre, inner gear 6, middle floating disc 7, output floating disc 8, input shaft 9 and output shaft 10, the external gear 5 of two arranged off-centre is housed on the input shaft 9, the left side external gear is connected with middle floating disc 7 by two on it pins 11, middle floating disc 7 connects right side external gear 5 by pair of pin 11, the right side external gear is connected with output floating disc 8 by two on it pins 11, output floating disc 8 connects output shaft 10 by pair of pin, inner gear 6 is by flat key connection cylinder 1, and cylinder is supported on input respectively by the diaxon bearing, on the output shaft.The output shaft of motor 2 connects input shaft 9 by coupler 12, and output shaft 10 is fixed in the right supporting 13.Input shaft is by left side supporting 14, output shaft 10 supportings.Left and right supporting is fixed on the base 15.Form brake equipment 4 by pump 16, spring 17, hydraulic actuating cylinder 18, block brake lock 19 and change-over valve 20.Coupler 12 places in 19.The block brake lock adopts brake application by spring, but hydraulic actuating cylinder leads to then brake off of oil, and by change-over valve control, braking effect is reliable in addition.
