Abstract
The invention discloses a roller with a water storage cavity. The roller comprises a roller body and a winch. The roller body comprises a fixed roller and a rotary roller, wherein the fixed roller is rotationally sleeved with the rotary roller. The water storage cavity is formed in the fixed roller and externally connected with a water delivery device. A first water outlet is formed in the upper end of the fixed roller. A plurality of second water outlets matched with the first water outlet are evenly formed in the rotary roller in the circumferential direction. When one of the second water outlets rotates to the outer side of the first water outlet, the water storage cavity communicates with the outside atmosphere. The automatic rotation characteristic of the rotary roller in the lifting process is utilized, when the rotary roller rotates slowly, heat generated by friction between the rotary roller and a steel wire rope is small, at this time, the number of water spraying in unit time is small, and therefore the water spray amount is small. When the rotary roller accelerates to rotate, heat generated by friction between the rotary roller and the steel wire rope is increased, at this time, the number of water spraying in unit time is increased, and therefore the water spray amount is increased, so that the optimal cooling effect is achieved.
Description
Technical field
The present invention relates to a kind of roller, this roller is specifically for elevating mechanism.
Background technology
In building site, common elevating mechanism is mainly made up of hoist engine and roller, and the steel wire rope on hoist engine bypasses roller,
In lifting process, between steel wire rope and roller, constantly friction generates heat, but is as the rising of temperature, steel wire rope and roller
Between because friction produce abrasion more serious.Additionally, hoist engine rotation is faster, it is faster that roller also turns, and then makes steel wire
Rope and roller between rub generation heat more.It is therefore desirable to being lowered the temperature steel wire rope to extend steel in lifting process
The service life of cord.
Content of the invention
For deficiency of the prior art, the present invention provides a kind of roller with water storage cavity, solves steel wire rope in lifting
During the too high problem of temperature.
The present invention is achieved through the following technical solutions.A kind of roller with water storage cavity, including roller and hoist engine, described
Roller includes fixed wheel and rotates the runner being set on described fixed wheel, is provided with water storage cavity, described storage tank is external in described fixed wheel
Water delivery device, the upper end of described fixed wheel is provided with first apopore, and on described runner, circumference is uniformly provided with several and institute
State the second apopore of the first apopore cooperation, when described second apopore goes to outside described first apopore, described storage
Water cavity connects with ambient atmosphere.During use, water delivery device does not stop toward water storage intracavity water filling so that water storage cavity is constantly in full shape
State；With the rotation of hoist engine, the steel wire rope on hoist engine drives runner to rotate, when the second apopore on runner goes to fixed wheel
On the first apopore outside when because water delivery device is always toward water storage intracavity water filling so that the water of water storage intracavity passes through the
One apopore and the second apopore circumference spray, and the steel wire rope above the water pair roller of ejection and roller is lowered the temperature.Additionally, volume
Raise machine rotation faster, between steel wire rope and runner because friction produce heat also more, simultaneously runner also rotate faster, this
When the unit interval in the frequency that goes to outside the first apopore of the second apopore uprise, the Surfacing frequency therefore within the unit interval
Become many, thus the water yield spraying within the unit interval becomes many, to reach optimal cooling-down effect.
As the optimization further of technique scheme, on the contact surface of described fixed wheel lateral wall and described runner medial wall
It is provided with eight balls, described eight ball circumferences are evenly distributed on described contact surface.Thus reducing when runner rotates and fixed wheel
Frictional force between lateral wall, extends the service life of roller.
Compared with prior art, the present invention utilizes runner this characteristic of rotation in lifting process, when runner slowly rotates,
Rub between runner and steel wire rope generation heat less, at this moment water spray number of times is few in the unit interval, and therefore injection flow rate is also few；When
Runner accelerates to rotate, and the heat of the generation that rubs between runner and steel wire rope increases, at this moment water spray increased frequency in the unit interval, because
This injection flow rate also increases, to reach optimal cooling-down effect.
Brief description
Fig. 1 is the use state figure of the present invention.
Fig. 2 is the structural representation of the present invention.
Fig. 3 is the scattergram of ball in the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings with specific embodiment, the invention will be further described.As Figure 1-3, one kind carries
The roller of water storage cavity, including roller 2 and hoist engine 1, described roller 2 includes fixed wheel 3 and rotation is set in turning on described fixed wheel 3
Wheel 4, is provided with water storage cavity 5 in described fixed wheel 3, the external water delivery device of described storage tank 5, and the upper end of described fixed wheel 3 is provided with one
First apopore 31, on described runner 4, circumference is uniformly provided with several the second apopores with described first apopore 31 cooperation
41, when described second apopore 41 goes to described first apopore, 31 outside, described water storage cavity 5 connects with ambient atmosphere.
In technique scheme, the contact surface of described fixed wheel 3 lateral wall and described runner 4 medial wall is provided with eight balls
6, described eight ball 6 circumferences are evenly distributed on described contact surface.
During use, water delivery device does not stop toward water filling in water storage cavity 5 so that water storage cavity 5 is constantly in full state；With elevator
The rotation of machine 1, the steel wire rope 11 on hoist engine 1 drives runner 4 to rotate, when the second apopore 41 on runner 4 goes on fixed wheel 3
The first apopore 31 outside when because water delivery device is always toward water filling in water storage cavity 5 so that the water in water storage cavity 5 passes through
First apopore 31 and the second apopore 41 circumference spray, and the steel wire rope 11 of the water pair roller 2 of ejection and roller 2 top is dropped
Temperature.Additionally, hoist engine 1 rotation is faster, because the heat of friction generation is also more between steel wire rope 11 and runner 4, runner 4 simultaneously
Also rotate is faster, and the frequency that in the at this moment unit interval, the second apopore 41 goes to outside the first apopore 31 uprises, and therefore exists
Surfacing frequency in unit interval becomes many, thus the water yield spraying within the unit interval becomes many.The present invention is with runner 4 and steel wire
The change of heat of generation of rubbing between rope 11 automatically adjusts the number of times of water spray, that is, automatically adjusts injection flow rate, to reach
Good cooling-down effect.
