The utility model is suitable for a spring drive's hose reel, have rational in infrastructure, design science, deceleration increase turn round, the energy storage is big, the advantage of easy maintenance, low price.
Description
Technical field
The utility model belongs to a kind of hose reel, particularly a kind of spring reel of speed change.
Background technology
Spring driven hose reel is the common components of truck tanker and water-tank lorry, and during use, operating personal is stretched and drawn flexible pipe, manually by the flexible pipe pull-out on revolving drum.Revolving drum rotates releases the inner spring installed while flexible pipe and is rolled tightly, and spring carries out accumulation of energy along with the rotation of revolving drum.Reel is provided with ratchet wheel positioning mechanism, can stretch during the process of drawing claims ensure revolving drum directional-rotation can locking at flexible pipe, after locking revolving drum fixedly stopped the rotation by ratchet device the flexible pipe that ensures to release can not by rollback under the effect of spring force again.Remove ratchet device locking after revolving drum under spring force contrarotation the hand-line reel of releasing is got back on revolving drum.The power of reel when regaining flexible pipe comes from the spring that revolving drum inside is installed completely, and when the sebific duct diameter that reel is equipped with increases, the weight of sebific duct self and the weight of revolving drum also can correspondingly increase, and this just needs larger spring force to drive.The oad using the larger spring of elastic force also just to cause spring strengthens, and revolving drum also needs increase could hold larger spring.So just create 2 problems: the weight of reel sharply increases, the change causing weight and oad with regard to needs increasing in order to the inner core diameter holding more big spring revolving drum is large thereupon; Its coefficient of stiffiness of spring after increasing has also become greatly, and predetermincd tension required during installation also makes more greatly mounting spring become difficulty.
The structure of reel self can cause repairs inconvenience: the operating spring of reel has installed the inside at revolving drum, just needs reel to decompose completely the difficulty increase work capacity just carrying out making repair and maintenance strengthen when repairing and change.
Utility model content
The purpose of this utility model is to solve the problem, and proposes a kind of spring reel with reductor, and the spring reel of this band reductor has rational in infrastructure, that the increasing of design science, reduction of speed is turned round, accumulation of energy is large, easy to maintenance, cheap feature.
The purpose of this utility model is achieved through the following technical solutions: the spring reel of band reductor, be provided with reel fixed support, it is characterized in that: described reel fixed support top is fixed with single-revolution cylinder, the both sides of described revolving drum are respectively equipped with chuck, a transmission shaft is installed at the center of described revolving drum, one end of described transmission shaft is fixed with a power wheel, the other end of described transmission shaft is provided with a ratchet, described ratchet is provided with a ratchet on the reel fixed support that it is corresponding, a clockwork spring energy storage is coaxially installed with bottom described reel fixed support, described clockwork spring energy storage is by shell, organize clockwork spring more, energy storage transmission shaft, train of reduction gears, accumulation of energy power wheel forms, described accumulation of energy power wheel is by driving band and power wheel gear.
Accumulation of energy power wheel, driving band, power wheel also can adopt the structure of chain, sprocket wheel or gear cluster.
The utility model makes installation become easy to be laborsaving by small spring as predetermincd tension required during its installation of drive source also corresponding diminishing; Spring be separated with revolving drum the inner core diameter of revolving drum can not be considered the installing space volume of spring is reduced; Spring device spring is separated latter two mechanism with revolving drum separate, can carry out separately during maintenance and repair, does not need to decompose difficulty and the work capacity that reel reduces repair and maintenance to the maintenance and repair of spring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: see accompanying drawing 1, with the spring reel of reductor, be provided with reel fixed support, described reel fixed support top is fixed with single-revolution cylinder 1, the both sides of described revolving drum are respectively equipped with chuck 2, a transmission shaft is installed at the center of described revolving drum, one end of described transmission shaft is fixed with a power wheel 3, the other end of described transmission shaft is provided with a ratchet, described ratchet is provided with a ratchet on the reel fixed support that it is corresponding, a clockwork spring energy storage 4 is coaxially installed with bottom described reel fixed support, described clockwork spring energy storage is by shell, organize clockwork spring more, energy storage transmission shaft, train of reduction gears, accumulation of energy power wheel forms, described accumulation of energy power wheel 5 is by driving band and power wheel gear.
Improve the drive configuration of reel, the position of operating spring is no longer arranged on the inner core of revolving drum.The individual components that operating spring is designed to a band housing is arranged on reel frame, to be connected row cutting of going forward side by side between operating spring with revolving drum by chain rotating mechanism.Chain rotating mechanism is designed to Reduced Speed Now: revolving drum is driven end, and operating spring mechanism is that drive end is run slowly according to the speed ratio i of setting by chain and sprocket wheel.Operating spring mechanism output torque M
1, rotating speed N
1being turned on revolving drum by link chain mechanism makes revolving drum rotate return.Link chain mechanism is speed reduction gearing, and speed ratio is i.According to the characteristic of retarder, operating spring mechanism output torque M
1, rotating speed N
1with the moment of torsion M acted on revolving drum
2, rotating speed N
2there is following relation: M
2/ M
1=i=N
1/ N
2the moment of torsion M acted on revolving drum can be calculated thus
2for M
1i doubly.I >=1 when mechanism designs for slowing down, it is exaggerated that torque drive spring device output torque M1 acts on revolving drum.The spring that elastic force so just can be used less drives larger revolving drum.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among protection domain of the present utility model.
