Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
In view of the problems in the prior art, the present utility model provides the following embodiments:
specific example I:
referring to fig. 1, a dual friction wheel type endless rope winch apparatus includes: a first friction wheel set 1, a second friction wheel set 2 and 1 driving assembly 3; the central lines of the first friction wheel set 1 and the second friction wheel set 3 are arranged in parallel and staggered by half a rope pitch in the horizontal direction, and the first friction wheel set 1 and the second friction wheel set 2 are used for enabling 1-number steel wire ropes s for dragging to be distributed in parallel; the driving assembly 3 is arranged between the first friction wheel set 1 and the second friction wheel set 2 and is used for driving the first friction wheel set 1 and the second friction wheel set 2 simultaneously; the arrow direction in fig. 1 is the direction of rotation of the first friction wheel set 1, the second friction wheel set 2 and the 1 drive assembly 3;
preferably, as shown in fig. 2, the first friction wheel set 1 includes: a first friction wheel 101 and a first driven gear 102; the first driven gear 102 is coaxially arranged on the first friction wheel 101; also, the second friction wheel set 2 includes: a second friction wheel 201 and a second driven gear 202; a second driven gear 202 is coaxially arranged on the second friction wheel 201; the first driven gear 102 and the second driven gear 202 are both in driving connection with the drive assembly 3.
Preferably, the driving assembly 3 includes: a driving unit 301, a reduction mechanism 302, and an active transmission unit 303; wherein, the speed reducing mechanism 302 is connected with the output end of the driving unit 301; the driving transmission unit 303 is connected with the output end of the speed reducing mechanism 302; the driving transmission unit 303 is in transmission connection with the first friction wheel set 1 and the second friction wheel set 2 at the same time; preferably, the driving transmission unit 303 is one of straight teeth, helical teeth, herringbone teeth or arc teeth; gears corresponding to the driving transmission unit 303 are respectively arranged on the first friction wheel 101 and the second friction wheel 201; when the driving gear unit 303 is a non-spur gear, the helix angles of the first driven gear 102 and the second driven gear 202 are exactly opposite.
When the first friction wheel set 1, the second friction wheel set 2 and the driving transmission unit 303 are connected through gear engagement, the single driving gear drives two large gears simultaneously, the main driving gear is changed from original single-tooth transmission into double-tooth transmission, so that the transmission force is doubled, the transmission power is doubled, the equipment volume can be reduced, and the equipment obtains larger power density; moreover, the first friction wheel set 1 and the second friction wheel set 2 simultaneously drive one steel wire rope, so that the friction performance of the steel wire rope can be improved, and the friction force is increased; moreover, the transmission among the first driven gear 102, the second driven gear 202, and the driving transmission unit 303 is not limited to straight teeth, and may be helical teeth, human teeth, or curved teeth; if non-straight teeth are adopted, the spiral angles of the transmission gears on the left friction wheel and the right friction wheel are opposite, so that the size has larger bearing capacity.
In this embodiment, since the brake wheel can be disposed on the intermediate shaft of the decelerator when the driving is performed by using one active transmission unit 303, the demand for braking force is reduced, and the braking demand can be satisfied with a relatively small braking force.
Specifically, as shown in fig. 3 and 4, the speed reducing mechanism 302 includes: a first shaft 3028, a first bevel gear 3021, a second bevel gear 3022, a first transition gear 3023, a second transition gear 3024, a second shaft 3025, a brake mechanism 3026, and an elastic coupling 3027; wherein, the first bevel gear 3021 is connected with the output end of the driving assembly 3; a second bevel gear 3022 coaxially provided on the first shaft 3028 and meshed with the first bevel gear 3021; a first transition gear 3023 is provided on the first shaft 3028; a second transition gear 3024 is meshed in parallel with the first transition gear 3023; a second shaft 3025 is arranged on said second transition gear 3024; the active transmission unit 303 is arranged at the end of the second shaft 3025; a brake mechanism 3026 is provided at an end of the first shaft 3028 remote from the second bevel gear 3022. The elastic coupling 3027 is arranged between the driving transmission unit 303 and the second shaft 3025.
In specific use, in order to raise the friction between the first friction wheel 101, the second friction wheel 201 and the towing wire rope S; pads M are uniformly distributed on the first friction wheel 101 and the second friction wheel 201 in the circumferential direction, such as M in fig. 5; the pad M is provided with a rope groove M1 matched with the diameter of the towing steel wire rope;
for stability, the pad M forms a trapezoid with a wide bottom and a narrow top in a radial section of the first friction wheel 101 or the second friction wheel 201, as shown in fig. 6 and 7; meanwhile, a rope groove M1 matched with the diameter of the towing steel wire rope is formed in the pad M; the bottom as described herein refers to the side near the first friction wheel 101 or the second friction wheel 201.
For convenience of assembly, the pad M includes: a first unit M101 and a second unit M102; wherein the second unit M102 is arranged in a matching manner with the first unit M101; the surfaces of the first unit M101 and the second unit M102 are provided with continuous rope grooves M1; in order to further increase the reliability of the pad M, the contact surfaces of the first unit M101 and the second unit M102 are oblique lines for improving stability.
Preferably, each pad M is composed of two trapezoidal first units M101 and second units M102, and a plurality of pads M are simultaneously installed in the first friction wheel 101 or the second friction wheel 201 and wedged in the circumferential direction;
by adding the pad M, when the steel wire rope is towed, n whole friction rings are formed between the first friction wheel 101 and the second friction wheel 201, so that the friction encircling angle is increased, the friction force is exponentially increased, and the magnification factor of the friction force is the power of mu x alpha of e, and is exponentially magnified; where e is the natural number of the euler equation e=2.718; μ is the coefficient of friction of the wire rope with the friction pad, μ=0.25; alpha is the radian of the contact surrounding angle of the steel wire rope and the liner;
because the stress of the outermost rope groove M1 may be large, the strength of the pad M exceeds the allowable range, when in implementation, the material of the outermost rope groove M1 on the first friction wheel 101 and the second friction wheel 201 adopts a metal material, and the middle adopts a high polymer material, so that the friction force can be obtained, the contact specific pressure of the steel wire rope can be borne, and the friction coefficient between the friction wheel and the steel wire rope can be improved as much as possible under the condition that the specific pressure can meet the contact requirement, so that the equipment obtains larger friction force; the outermost rope groove M1 in this context refers to the rope groove in which the wire rope is first wound.
What needs to be clarified is: the technical solutions not fully recorded in this document are all prior art. The embodiment of the utility model is not limited to common mine lifting and common hoisting operation, and can be used for occasions needing to drag objects quickly, such as a manual wave making machine, with large work load or other similar occasions.
The foregoing is merely illustrative of the present utility model, and the present utility model is not limited to the specific embodiments, and any person skilled in the art can easily change or replace the specific embodiments within the scope of the present utility model. The protection scope of the utility model is therefore subject to the claims.
