Description

Technical Field

[0001] The utility model belongs to the technical field of brakes, in particular to a brake used in multiple temperature environments for a winch or an anchor windlass. Background Art

[0002] The brake used in the existing winch is a hydraulic brake. The hydraulic oil in the oil cylinder of the hydraulic brake will solidify in an ultra-low temperature environment. At the same time, the pipeline of the brake cylinder is relatively thin, and it is difficult to achieve the heat insulation effect on the open deck. As a result, the hydraulic oil in the oil cylinder and the hydraulic oil in the pipeline cannot operate normally, resulting in safety brake failure and the inability to complete manual emergency. At the same time, the use of traditional hydraulic methods for braking is very likely to cause environmental pollution. Therefore, it is urgently needed to design a brake for winch or anchor windlass in multi-temperature environments to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide a brake for a winch or an anchor windlass in multiple temperature environments, which solves the problem that the existing hydraulic brake cannot meet the use requirements of ultra-low temperature environments.

[0004] In order to solve the above technical problems, the utility model provides a brake for winch or windlass in multiple temperature environments, comprising a motor, a reducer, an electric push rod and a brake belt connected to the electric push rod through a conversion assembly arranged in sequence from top to bottom, wherein the brake belt is arranged in an annular shape.

[0005] The conversion assembly includes a linkage plate, a fixing frame and a connecting frame. One end of the linkage plate is fixed to the outer wall of one end of the brake belt, and the other end is connected to the fixing frame through a first pin. The fixing frame is fixedly arranged on the winch frame, and a second pin is embedded in the end away from the first pin.

[0006] One side of the connecting frame is connected to the outer side wall of the fixing frame through a third pin shaft, one end of the connecting frame is connected to the other end of the brake band through a fourth pin shaft, and a fifth pin shaft is embedded in the other end of the connecting frame, and the lower end of the electric push rod passes through the fifth pin shaft and is threadedly engaged with the second pin shaft. The reducer drives the electric push rod to rotate, so that the lower end of the electric push rod rotates up and down in the second pin shaft, thereby driving the connecting frame to tilt and driving the brake band to loosen or tighten.

[0007] Furthermore, the electric push rod includes a sleeve, a rod and a spring. The sleeve is fixed to the winch frame through a sixth pin and a fixing member. The rod is inserted into the sleeve, and its lower end extends out after passing through the sleeve and is threadedly engaged with the second pin. The spring is sleeved on the rod and is used for extension or compression between the rod and the sleeve.

[0008] Furthermore, the lower end of the rod body is a threaded section.

[0009] Furthermore, a threaded hole cooperating with the threaded section is formed on the second pin shaft.

[0010] Furthermore, a plurality of proximity switches are provided on the outer wall of the sleeve.

[0011] Furthermore, the number of the plurality of proximity switches is two, and the two proximity switches are arranged on the sleeve at intervals.

[0012] Furthermore, a mounting groove for mounting a handwheel is provided on the motor, and the mounting groove is located at the top of the rotating shaft of the motor.

[0013] Furthermore, a first fastener for limiting the other end of the brake band from being disengaged is passed through the end of the fourth pin shaft.

[0014] Furthermore, a second fastener for limiting a relative position with respect to the rod body is passed through the end of the fifth pin.

[0015] The beneficial effects of the utility model are as follows: the motor and reducer in the brake of the utility model control the rotation of the electric push rod and convert the rotary motion of the motor into the linear motion of the electric push rod through the conversion component, thereby tightening or loosening the brake band, thereby improving the degree of cooperation and braking between the brake band and the cylindrical structure such as the anchor chain wheel or the reel, increasing the braking effect of the winch, and being able to meet the use conditions of different temperatures, so as to solve the problem that the existing hydraulic brake cannot operate due to the solidification of hydraulic oil;

[0016] The coordination of the conversion assembly and the electric push rod enables the electric push rod to rotate under the rotational driving force of the motor and the reducer, and the fixed frame is fixed on the winch frame to fix the fixed frame, and the threaded section at the lower end of the rod body of the electric push rod rotates in the threaded hole in the second pin shaft to drive the connecting frame to move up and down simultaneously with the electric push rod, converting the rotational motion force of the motor into the linear motion force of the rod body of the electric push rod, so as to loosen or tighten the brake belt, thereby increasing the adjustability of the brake belt tightness.

[0017] The setting of the electric push rod can make the rod body extend or compress between the rod body and the sleeve body under the elastic force of the spring, so as to improve the controllability of the moving distance of the rod body in the sleeve body. In addition, a proximity switch is provided on the outer wall of the sleeve body, so that the upper limit position on the outer wall of the rod body drops and moves toward the proximity switch away from the threaded section of the rod body, so that the brake band can hold the cylindrical structure such as the anchor chain wheel or the reel tightly, and the lower limit position on the outer wall of the rod body rises and approaches the proximity switch close to the threaded section of the rod body, triggering the proximity switch to stop the brake band from loosening, so as to prevent the problem that the brake band is always open and cannot be controlled;

[0018] The end of the fourth pin is provided with a first fastener for limiting the other end of the brake band from being disengaged, which can effectively prevent the other end of the brake band from being disengaged from the fourth pin and effectively fix the other end of the brake band, thereby avoiding the problem of the brake band being disengaged and causing overturning and injuring people or damaging the winch, thereby effectively extending the service life of the winch;

[0019] The end of the fifth pin is provided with a second fastener for limiting the relative position with the rod body, so that the rod body and one end of the connecting frame can move simultaneously, so that the connecting frame acts as a lever, and the other end of the connecting frame moves downward or upward, thereby loosening or tightening the brake band, which can effectively avoid the problem that the connecting frame is separated from the rod body and the brake band when the lever acts and fails to achieve the leverage effect.

[0025] The following is a specific embodiment of the present invention and the attached Figure 1-2In detail, a brake for a winch or windlass in a multi-temperature environment is disclosed, which includes a motor 2, a reducer 3, an electric push rod 4, and a brake belt 6 connected to the electric push rod 4 through a conversion component 5, which are arranged in sequence from top to bottom. The brake belt 6 is arranged in a ring shape.

[0026] The conversion assembly 5 includes a linkage plate 51, a fixing frame 52 and a connecting frame 53. One end of the linkage plate 51 is fixed to the outer wall of one end of the brake belt 6, and the other end is connected to the fixing frame 52 through a first pin shaft 54. The fixing frame 52 is fixedly set on the winch frame, and a second pin shaft 55 is embedded in the end away from the first pin shaft 54. A threaded hole is opened on the outer wall of the second pin shaft 55.

[0027] One side of the connecting frame 53 is connected to the outer wall of the fixing frame 52 through the third pin shaft 56, one end of the connecting frame 53 is connected to the other end of the brake belt 6 through the fourth pin shaft 57, and a fifth pin shaft 58 is embedded in the other end of the connecting frame 53. The lower end of the electric push rod 4 passes through the fifth pin shaft 58 and is threadedly engaged with the second pin shaft 55.

[0028] The speed reducer 3 drives the electric push rod 4 to rotate, so that the lower end of the electric push rod 4 rotates up and down in the second pin shaft 55, thereby driving the connecting frame 53 to tilt and driving the brake belt 6 to loosen or tighten.

[0029] The electric push rod 4 includes a sleeve 41, a rod 42 and a spring 43. The sleeve 41 is fixed to the winch frame by a sixth pin 44 and a fixing piece. The lower end of the rod 42 is a threaded section 421. The outer wall of the rod 42 is provided with an upper limit and a lower limit. The rod 42 is inserted into the sleeve 41, and the threaded section 421 at its lower end extends out after passing through the sleeve 41 and is threadedly engaged with the threaded hole of the second pin 55. The spring 43 is sleeved on the rod 42 and is used for the extension or compression between the rod 42 and the sleeve 41. The setting of the electric push rod 4 can make the rod 42 extend or compress between the sleeve 41 under the elastic force of the spring 43, so as to improve the controllability of the moving distance of the rod 42 in the sleeve 41.

[0030] The coordinated arrangement of the conversion assembly 5 and the electric push rod 4 allows the electric push rod 4 to rotate under the rotational driving force of the motor 2 and the reducer 3, and the fixing frame 52 is fixed on the winch frame to fix the fixing frame 52, and the threaded section 421 at the lower end of the rod body of the electric push rod 4 rotates in the threaded hole in the second pin shaft 55 to drive the connecting frame 53 to move up and down simultaneously with the electric push rod 4, and convert the rotational motion force of the motor 2 into the linear motion force of the rod body 42 of the electric push rod 4, so that the brake belt 6 can be loosened or tightened, thereby increasing the adjustability of the tightness of the brake belt 6.

[0031] A plurality of proximity switches 45 are provided on the outer wall of the sleeve 41. The number of the plurality of proximity switches 45 is two, and the two proximity switches 45 are spaced apart on the sleeve 41. The upper proximity switch 45 is provided away from the threaded section 421. The upper proximity switch 45 away from the threaded section 421 is used to cooperate with the upper limit position on the outer wall of the rod body 42 for limiting position. The lower proximity switch 45 is provided near the threaded section 421. The lower proximity switch 45 near the threaded section 421 is used to cooperate with the lower limit position on the outer wall of the rod body 42 for limiting position.

[0032] A proximity switch 45 is provided on the outer wall of the sleeve 41, so that the upper limit position on the outer wall of the rod body 42 drops and moves toward the proximity switch 45 away from the threaded section 421 of the rod body 42, so that the brake belt 6 holds the cylindrical structure such as the anchor chain wheel or the reel, and the lower limit position on the outer wall of the rod body 42 rises and approaches the proximity switch 45 close to the threaded section 421 of the rod body 42, triggering the proximity switch 45 to stop the brake belt 6 from loosening, so as to prevent the problem that the brake belt 6 is always open and cannot be controlled.

[0033] The motor 2 is provided with a mounting groove for mounting the handwheel 1 , and the mounting groove is located at the top of the rotating shaft of the motor 2 . The handwheel 1 can be installed in the mounting groove on the motor 2 as required.

[0034] The end of the fourth pin 57 is penetrated by a first fastener for limiting the detachment of the other end of the brake band 6. The end of the fourth pin 57 is penetrated by a first fastener for limiting the detachment of the other end of the brake band 6, which can effectively prevent the other end of the brake band 6 from detaching from the fourth pin 57, effectively fix the other end of the brake band 6, and avoid the problem of the brake band 6 detaching and causing overturning and injuring people or damaging the winch, thereby effectively improving the service life of the winch.

[0035] The end of the fifth pin shaft 58 is provided with a second fastener for limiting the relative position with the rod body 42, so that the rod body 42 and one end of the connecting frame 53 can move simultaneously, so that the connecting frame 53 acts as a lever, and the other end of the connecting frame 53 moves downward or upward, so that the brake belt 6 is loosened or tightened, which can effectively avoid the problem that the connecting frame 53 is separated from the rod body 42 and the brake belt 6 when the lever acts and fails to achieve the leverage effect.

[0036] The motor 2 and the reducer 3 in the brake of the present invention control the rotation of the electric push rod 4 and convert the rotational motion of the motor 2 into the linear motion of the rod body of the electric push rod 4 through the conversion component 5, thereby tightening or loosening the brake belt 6, so as to improve the degree of braking coordination between the brake belt 6 and the cylindrical structure such as the anchor chain wheel or the reel, increase the braking effect of the winch, and meet the use conditions of different temperatures, so as to solve the problem that the existing hydraulic brake cannot operate due to the solidification of hydraulic oil.

[0037] The brake of the utility model is a band brake.

[0038] The workflow of this utility model:

[0039] The working process of the band brake is in two states: clamping and releasing:

[0040] The motor 2 is started, and the motor 2 drives the reducer 3 to rotate, and the reducer 3 drives the electric push rod 4 to rotate. Because the sleeve 41 of the electric push rod 4 is fixed to the winch frame, the rod body 42 rotates, and the threaded section 421 at the lower end of the rod body 42 rotates up and down in the threaded hole of the second pin 55 embedded in the end of the fixing frame 52. Because the fixing frame 52 is fixed to the winch frame, the rotational motion of the motor 2 is converted into the linear motion of the rod body 42 of the electric push rod 4, and the rod body 42 drives one end of the connecting frame 53 connected thereto to move up and down at the same time, and the other end rotates around the third pin 56 to make it move downward or upward, so that the connecting frame 53 tilts, and at the same time drives one end of the brake band 6 to move closer to or away from the other end of the brake band 6, so that the two ends of the brake band 6 are tightened or loosened with each other, and the degree of closing of the brake band 6 can be accurately adjusted by the height of the screwing between the threaded section 421 of the rod body 42 of the electric push rod 4 and the second pin 55.

[0041] When the band brake is required to work, the motor 2 rotates forward, and the rod body 42 of the electric push rod 4 rotates. Since the sleeve 41 is fixed to the winch frame, the rod body 42 moves downward in the sleeve 41, and the threaded section 421 at its lower end is screwed downward in the threaded hole of the second pin 55, and one end of the connecting frame 53 connected to the rod body 42 moves downward with the rod body 42. Since the fixing frame 52 is fixed to the winch frame, the other end of the connecting frame 53 tilts due to the downward movement of one end and the rotatable force of the third pin 56. One end of the brake band 6 is pushed by the other end of the connecting frame 53 and compressed to the other end, so that the brake band 6 is tightly held by a cylindrical structure such as a chain wheel or a drum, and at the same time, the upper limit on the outer wall of the rod body 42 stops moving toward the previous proximity switch 45 away from the threaded section 421, and the setting of the previous proximity switch 45 is used to set the maximum tightening position of the brake band 6.

[0042] When the brake mechanism closing button is pressed or the motor 2 is powered off, the brake of the motor 2 is automatically opened, the spring 43 in the rod body 42 is extended, and the electric push rod 4 is pushed to reverse, thereby driving the reducer 3 and the motor 2 to reverse until the spring 43 is extended to the initial brake position and stops. That is, when the lower limit on the outer wall of the rod body 42 contacts the next proximity switch 45 close to the threaded segment 421, the two ends of the brake belt 6 of the band brake are loosened, and the brake mechanism will start the automatic braking function at this time, thereby achieving the purpose of failure safety protection.

[0043] When it is necessary to manually control the tightening of the brake belt 6 of the band brake, install the handwheel 1 into the mounting groove and turn the handwheel 1 to drive the reducer 3 and the electric push rod 4 to rotate, and convert the rotary motion into linear motion of the rod body 42 of the electric push rod 4, so that the boss on the outer wall of the rod body 42 compresses the spring 43 in the sleeve 41, and the rod body 42 drives one end of the connecting frame 53 connected to it to move downward, and the connecting frame 53 tilts. One end of the brake belt 6 is pushed by the other end of the connecting frame 53 and is compressed with the other end, so that the band brake is tightened. At the same time, after opening the brake mechanism equipped on the motor 2, the handwheel 1 is locked.

[0044] When it is necessary to manually control the loosening of the brake band 6 of the band brake, there is no need to reverse the handwheel 1. The spring 43 in the sleeve 41 will automatically extend under the elastic force, and the rod body 42 will reverse under the elastic force of the spring 43 and the force of the brake mechanism on the motor 2 in the open state. The reducer 3 and the motor 2 will reverse accordingly until the spring 43 extends to the initial position of the brake and stops. That is, when the lower limit on the outer wall of the rod body 42 contacts the next proximity switch 45 near the threaded segment 421, the two ends of the brake band 6 of the band brake are loosened.

[0045] The above disclosure is only a preferred embodiment of the present invention and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
