The utility model has the advantages of best safety, small volume, time and labor efficiency, and is particularly suitable to be used in coalmine wells and oil fields.
Description
Technical field
The utility model relates to a kind of bont, particularly a kind of hydraulic hoisting machine.
Background technology
At present, the bont of domestic use has chain block, electric block and pneumatic cucurbit.Electric block uses in the flammable explosive gas place, and danger is very big; And pneumatic cucurbit volume is big, and weight is big, difficult, and the air compression plant that matches with it needs the construction cost of great number; What the hoisting operation use was maximum under the present coal mine is bottle gouard moved by hands, weight-lifting equipment is hung under the face roof, realize the lifting of weight by operation manually, thisly mainly form weight-lifting equipment by pulley, suspension hook, steel rope, though have mechanical labour-saving advantage, but only, not only time-consuming by artificial physical lifting, also require great effort very much.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned weak point, and a kind of safety is good, volume is little and provide, and save time, laborsaving, be particularly useful for the hydraulic hoisting machine in the coal, oil field well.
The utility model is to realize like this, this hydraulic hoisting machine comprises hydraulic control device, HM Hydraulic Motor, HM Hydraulic Motor is fixed on the shell, this HM Hydraulic Motor links to each other with transmission main shaft by elastic coupling, and HM Hydraulic Motor is to provide fluid pressure by hydraulic control device, establishes ratchet, drg and reducing gear on the transmission main shaft successively, this reducing gear is connected with chain hoist wheel by spline, chain hoist wheel is placed on the transmission main shaft, and which is provided with chain, and hook under the lifting is established in this chain lower end.
As a kind of improvement of the present utility model, described shell is made as left and right two shells, be provided with the gap in the middle of two shells, described chain hoist wheel is located in the two shell gaps, and described elastic coupling, ratchet and drg are located in the left shell, and described reducing gear places in the right casing, between described two shells, and establish above described chain hoist wheel and rise to the bait, described shell is provided with ratchet, and this ratchet is corresponding with described ratchet.
Because HM Hydraulic Motor of the present utility model is to be to drive media with the highly pressurised liquid, can not produce any spark, has safe and reliable advantage, especially applicable to the flammable explosive gas place.Hydraulic control device is used for controlling or regulating the fluid pressure of HM Hydraulic Motor that Hydraulic Station offers, flow and direction, and it can guarantee the normal operation of HM Hydraulic Motor.HM Hydraulic Motor is the power resources of gig, and what it was firm is contained on the shell, by it the straight-line motion of liquid is transformed into to rotatablely move.Coupler is that HM Hydraulic Motor and transmission main shaft are associated in together, and coupler rises and connects the braking double action, and braking is after being used for guaranteeing that weight promotes, and rests on any position and does not glide, and guarantees complete operation.Speed-changing mechanism is the two-stage gear reduction, and a reduction of speed increases torsion effect and reaches desired speed through deceleration.Lift system is that the chain hoist wheel rotation has driven chain row culture straight-line motion up and down, is used for reaching the effect that promotes weight.The utility model is also on shell, and establishes above chain hoist wheel and rise to the bait, so that the utility model hydraulic hoisting machine is fixed in employed correct position; Also be provided with ratchet on the transmission main shaft, ratchet is fixed on the shell, and ratchet is corresponding with ratchet, is used for controlling transmission main shaft and guarantees a direction rotation.The utility model hoisting force height, volume is little, and is in light weight, safe and reliable, is convenient to carrying and installation, of many uses, the weight that is suitable for various places promotes, be particularly useful under the mine can not electricity consumption the place, and have and improve working conditions multiple advantage easy to maintenance.
Description of drawings
Fig. 1 is the utility model hydraulic hoisting machine structural representation.
The specific embodiment
As shown in Figure 1, the utility model hydraulic hoisting machine mainly comprises hydraulic control device 1, HM Hydraulic Motor 2, HM Hydraulic Motor 2 is fixed on the shell 3, this HM Hydraulic Motor 2 links to each other with transmission main shaft 5 by elastic coupling 4, half and the motor 2 that are coupler 4 join, second half and transmission main shaft 5 join, half that connects with transmission main shaft 5 be coupler be again drg, coupler 4 has played connection, the braking double effects, the utility model is established ratchet 6 successively on transmission main shaft 5, drg 7 and reducing gear 9, reducing gear 9 adopts double reduction, promptly adopt big, little four gears are as speed reduction gearing, this reducing gear 9 is connected with chain hoist wheel 8 by spline, this chain hoist wheel 8 is placed on the transmission main shaft 5, be that place, chain hoist wheel 8 axle center establishes through hole, transmission main shaft 5 passes through hole, transmission main shaft 5 is not given chain hoist wheel 8 transferring power, but reducing gear 9 is passed to chain hoist wheel 8 by spline with power, chain hoist wheel 8 is provided with chain 81, hook 82 under the lifting is established in these chain 81 lower ends, HM Hydraulic Motor 2 is to provide fluid pressure by hydraulic control device 1, the straight-line motion of liquid is transformed into rotatablely moves, and pass transmission main shaft 5 with power, transmission main shaft 5 is by reducing gear 9 transferring power, promote and make chain hoist wheel 8 rotations, chain 81 be about to weight.HM Hydraulic Motor 2 is to be to drive media with the highly pressurised liquid, employed highly pressurised liquid available hydraulic oil, and yet available emulsion can not produce any spark, has safe and reliable advantage.The utility model shell 3 is made as left and right two parts, be provided with spacing in the middle of two shells, chain hoist wheel 8 is located between two shells in the space, elastic coupling 4, ratchet 6, drg 7 are located in the left shell, and reducing gear 9 places in the right casing, fixed pawl 61 on left shell, and this ratchet 61 is corresponding with ratchet 6; The utility model is established an adapter plate between two shells, adapter plate is established through hole, establishes by this hole and rises to the bait 83, rises to the bait 83 to be used for the utility model hydraulic hoisting machine is fixed in employed correct position.
