Description

Technical Field

[0001] The utility model relates to the technical field of brakes, in particular to a brake and a brake monitoring device. Background Art

[0002] At present, the brake is mainly used when the unit is shut down, by increasing the friction resistance of the unit and accelerating the speed reduction. The reliable and accurate use of the brake is the basic condition to ensure the safe operation of the unit and the safe work of the operation and maintenance personnel. When the unit is operating normally, the brake should be withdrawn. When the speed drops to the specified speed during the unit shutdown process, the brake needs to be put in to avoid the unit running at a low speed for a long time, causing dry friction of the unit bearing and the occurrence of bearing burning accidents. In addition, when the unit is shut down and there is work inside the unit, the brake needs to be put in to prevent the unit from malfunctioning and prevent the unit from rotating suddenly.

[0003] Currently, the brake status is only monitored through mechanical contacts, and after the unit has been running for a long time, the position of the mechanical contact sensor will change, making it impossible to monitor the brake status. In addition, among the multiple brakes used in the braking process of the unit, the force applied to the brake during the braking process cannot be collected, and the gap between the brake and the rotor and the rotor speed cannot be collected; at the same time, after being used for a long time, the piston is prone to offset and getting stuck, resulting in the brake plate being unable to recover in time.

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1 , which is the first embodiment of the utility model. This embodiment provides a brake that can ensure the normal use of the brake. It includes a brake component 100 and an adjustment component 200. The height of the brake component 100 is adjusted by setting the adjustment component 200, thereby ensuring that the brake can be accurately deployed and retracted.

[0032] Specifically, the brake assembly 100 includes a base 101, a brake plate 102 arranged on the base 101, and an oil-operated part 103 and a pneumatic part 104 connected to the bottom end of the base 101; the height of the base 101 is adjusted by the oil-operated part 103 or the pneumatic part 104 to ensure the normal use of the brake. When the pneumatic piston gets stuck after being used for a long time, the base 101 can be driven by the oil-operated part 103, so that the brake plate 102 can be used normally.

[0033] Furthermore, the adjustment assembly 200 is arranged inside the base 101, and includes a clamping member 201 arranged between the base 101 and the oil-actuated member 103, and a fixing member 202 arranged between the pneumatic member 104 and the base 101. By providing the clamping member 201 and the fixing member 202, the oil-actuated member 103 or the pneumatic member 104 can be switched to prevent the piston from being stuck and unable to be used normally, thereby ensuring the normal use of the brake, so that the unit can operate safely.

[0034] When in use, the pneumatic part 104 is used to drive the base 101 to rise or fall. When the piston of the pneumatic part 104 is stuck and the base 101 cannot be reset, the oil-actuated part 103 is started, and the connection between the oil-actuated part 103 and the base 101 is switched through the clamping part 201 and the fixing part 202, so as to drive the base 101 to rise or fall, thereby driving the brake plate 102 to rise and fall.

[0035] In summary, by providing the brake assembly 100 and the adjustment assembly 200, it is possible to prevent the piston from getting stuck, thereby ensuring the normal use of the brake.

[0036] Example 2

[0037] Reference Figures 2 to 6 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides further optimization of the brake and solves the problem of how to prevent the piston from getting stuck. It includes the oil-operated part 103 including a connecting rod 103a movably connected to the bottom end of the base 101, an oil-operated piston 103b fixedly connected to the end of the connecting rod 103a, and a brake oil chamber 103c slidably connected to the oil-operated piston 103b. In the utility model, the internal space of the brake oil chamber 103c is divided into an upper chamber and a lower chamber by the oil piston 103. The two parts are respectively connected to pipelines, connecting the pressure oil source and the return oil. When the brake plate 102 needs to be raised, the pressure oil source is connected to the lower chamber of the brake through the oil pipe, and the return oil is connected to the upper chamber, which pushes the oil piston 103b upward and drives the connecting rod 103a to move upward, thereby raising the brake plate 102. When the brake plate 102 returns, the upper chamber is connected to the pressure oil and the lower chamber is connected to the return oil, which drives the oil piston 103b to descend, thereby returning the brake plate 102.

[0038] Specifically, the pneumatic part 104 includes a brake rod 104a movably connected to the bottom end of the brake plate 102, a pneumatic piston 104b fixedly connected to the end of the brake rod 104a and slidably connected to the brake oil chamber 103c, and a brake air chamber 104c slidably connected to the pneumatic piston 104b. In the utility model, the brake air chamber 104c is divided into two parts by the pneumatic piston 104b, a pneumatic upper chamber and a pneumatic lower chamber. When it is necessary to raise the brake plate 102, the pneumatic upper chamber is connected to the compressed air source through a pipeline, and the pneumatic lower chamber is connected to the atmosphere. At this time, the pneumatic piston 104b rises and drives the base 101 to rise through the brake rod 104a. When it is necessary to restore the brake plate 102, atmospheric air is connected to the pneumatic upper chamber, the compressed air inside is discharged, and the brake plate 14 falls.

[0039] Furthermore, the clamping member 201 includes at least two groups of positioning blocks 201a movably connected to the base 101, a return spring 201b arranged between the positioning rod 201a and the base 101, and a positioning groove 201c arranged at the end of the connecting rod 103a and matching the positioning block 201a. In the present invention, a circular groove matching the connecting rod 103a is provided on the base 101, and two groups of positioning blocks 201a are provided on both sides of the circular groove. At the same time, grooves matching the positioning blocks 201a are provided on the base 101 on both sides of the circular groove. When the connecting rod 103a moves upward, the side will apply force to the connecting rod 103a, so that the positioning block 201a compresses the return spring 201b and retracts into the base 101 until the positioning groove 201c on the connecting rod 103a is located at the position of the positioning block 201a. The positioning block 201a extends out under the action of the return spring 201b and is inserted into the positioning groove 201c, connecting the connecting rod 102a with the base 101, so that the connecting rod 102a drives the brake plate 102 to rise or fall.

[0040] The fixing member 202 includes a pressure rod 202a which is slidably connected to the base 101 and movably connected to the connecting rod 103a, two groups of fixing rods 202b which are fixedly connected to the pressure rod 202a, a connecting block 202c which is slidably connected to the fixing rod 202b, a moving rod 202d which is fixedly connected to the connecting block 202c and movably connected to the base 101, a clamping block 202e which is fixedly connected to the moving rod 202d and movably connected to the base 101, and a clamping groove 202f which is arranged on the brake rod 104a and matches the clamping block 202e; wherein a telescopic spring 202g is arranged at the end of the pressure rod 202a and the base 101. In the utility model, at the beginning, the brake plate 102 is driven by the pneumatic member 104, the base 101 is connected to the brake rod 104a, and two sides of the bottom end of the base 101 are provided with hole grooves which match the brake rod 104a, and the inner side of the hole groove is movably provided with a clamping block 202e. At the beginning, the slot 202f on the brake rod 104a is connected to the block 202e. When the pneumatic part 104 fails or the pneumatic piston is stuck, the oil-actuated part 103 needs to be put into operation, and the connecting rod 103a rises under the drive of the oil-actuated piston 103b, and the end of the connecting rod 103a first contacts the pressure rod 202a, and the connecting rod 103a continues to move upward and pushes up the pressure rod 202a until the positioning block 201a is engaged in the positioning slot 201c on the connecting rod 103a. When the pressure rod 202a moves upward, the connecting blocks 202c on both sides are driven to move through the fixed rod 202b. The end of the connecting block 202c connected to the fixed rod 202b moves upward together with the movement of the pressure rod 202a. The other end of the connecting block 202c is connected to the moving rod 202d, and the moving rod 202d can only move left and right, so that the other ends of the two groups of connecting blocks 202c pull the moving rod 202d to move toward the middle, so that the two groups of card blocks 202e move inward and separate from the card slot 202f, so that the brake rod 104a is separated from the base 101, and at this time the brake plate 102 is driven by the oil-actuated part 103. When the pneumatic part 104 is repaired and the pneumatic piston is used normally, the pneumatic piston 104b moves upward until it contacts the top of the hole groove at the bottom of the base, and continues to move upward, lifting the base 101 upward. At this time, the base 101 applies force to the positioning block 201a, so that the positioning block 201a compresses the reset spring 201b to retract inward, and the positioning block 201a is separated from the positioning groove 201c. The pressure on the pressure rod 202a contacts and resets under the action of the telescopic spring 202g, driving the connecting blocks 202c on both sides to move downward, so that the moving rods 202d on both sides move outward at the same time, driving the clamping block 202e to move outward, and clamping into the clamping groove 202f, fixing the base 101 and the brake rod 104a. When the brake rod 104a drives the brake plate 102 to move upward, the oil piston 103b is in a balanced state, and the connecting rod 103a is in a stopped state.

[0041] Furthermore, the connecting block 202c is provided with a slide groove 202c-1, in which a fixing rod 202b is movably provided. The fixing rod 202b slides in the slide groove 202c-1 driven by the pressure rod 202a, which can effectively prevent the connecting block 202c from being stuck and unable to move during use.

[0042] When in use, the pneumatic part 104 is connected to the base 101 through the fixing part 202 to drive the brake plate 102 to rise or fall. When the piston in the pneumatic part 104 is stuck or the air source disappears, the oil-driven part 103 is put in, connected to the base 101 through the clamping part 103, and the fixing part 202 is separated from the pneumatic part 104. At this time, the oil-driven piston 103b drives the connecting rod 103a and the base 101 to realize the rise or fall of the brake plate 102 until the pneumatic part 104 is restored.

[0043] In summary, by providing the oil-actuated part 103, the pneumatic part 104, the clamping part 201, and the fixing part 202, it is possible to realize automatic switching of the oil-actuated part 103 or the pneumatic part 104 drive, thereby preventing the piston from getting stuck and ensuring the normal use of the brake plate 102. The brake plate 102 of the brake is connected to the piston through the connecting rod 103a or the brake rod 104a. The upper surface of the brake plate 102 contacts the rotor during braking to form friction, so that the rotor slows down. The pneumatic piston 104b is arranged in the brake air chamber 104c, and the oil-actuated piston 103b is arranged in the brake oil chamber 103c. By adjusting the position of the piston, the length of the connecting rod 103a or the brake rod 104a is controlled to adjust the force of the brake plate 102 during braking.

[0044] Example 3

[0045] Reference Figure 1, which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a brake monitoring device, which solves the problem of how to collect the brake state, the pressure on the brake, the gap between the brake and the rotor, and the rotor speed. It includes a monitoring component 300, which is arranged on the base 101, including a control component 301, and a monitoring unit 302 arranged on the base 101 and electrically connected to the control component 301. The monitoring unit 302 collects the brake state, the pressure on the brake, the gap between the brake and the rotor, and the rotor speed in real time, and transmits the collected data to the control component 301, which is processed and analyzed by the control component 301, and an analysis model is established. After analyzing and processing a large amount of collected data, a prediction model is established to predict the length of the connecting rod 103a or the brake rod 104a that needs to be adjusted when all brakes are subjected to the same pressure, and to issue a command to control the air source and the oil source, so as to control the pneumatic parts 104 and 103 to drive the connecting rod 103a or the brake rod 104a to move up or down.

[0046] Specifically, the monitoring unit 302 includes a pressure sensor 301a arranged on the top of the base 101, a speed sensor 302a arranged on both sides of the base 101, a gap measurement sensor 303, and a state acquisition component 304 arranged between the base 101 and the outer side of the brake air chamber 104c. Two groups of speed sensors 302a and two groups of gap measurement sensors 303 are respectively arranged on both sides of the brake plate 102. The speed sensor 302a is used to monitor the speed of the rotor rotation. The gap measurement sensor 303 measures the distance between the brake and the rotor. The measurement result and the brake state acquisition device jointly monitor the position of the brake. The pressure sensor 301a collects the pressure on the brake during braking. The collected pressure and the gap measured by the gap measurement sensor 303 are calculated and analyzed by the control component 301 to obtain the distance that the brake rod 104a or the connecting rod 103a needs to be adjusted, so as to adjust the height of the brake during braking. The terminal controller stores the data collected by each sensor and establishes an analysis model. Through the calculation and analysis of a large amount of collected data, the length of the connecting rod when all brakes are subjected to the same pressure is realized through the prediction model output, and the pneumatic part 104a is controlled to adjust the distance of the brake rod 104a, thereby realizing the simultaneous adjustment of the height of all brakes. The state acquisition component 304 is used to collect the state of the brake plate 102, whether it is in the braking state or the reset state.

[0047] Further, the state acquisition component 304 includes a transmission rod 304a fixedly connected to one side of the base 101, a sensing block 304b arranged on the transmission rod 304a, two sets of sensing rotating rods 304c that are in active contact with the sensing block 304b and are rotatably connected to the outer side of the brake air chamber 104c, and two sets of limit blocks 304d that are arranged on one side of the two sets of sensing rotating rods 304 and are symmetrically arranged; wherein the limit blocks 304d are fixedly arranged on the outer side of the brake air chamber 104c. The state acquisition component 304 is connected to the transmission rod 304a on one side of the brake plate 102, the transmission rod 304a and the brake plate 102 move simultaneously, the sensing block 304b is arranged at a suitable position of the transmission rod 304a, and two sets of sensing rotating rods 304c are arranged at a suitable position outside the brake air chamber 104c, the sensing rotating rod 304c located on the upper side can only rotate upward under the action of the limit block 304d, and the sensing rotating rod 304c located on the lower side rotates downward under the action of the limit block 304d. When the brake plate 102 is braked, the sensing block 304b contacts the sensing rotary rod 304c on the upper side, triggering a signal for the brake plate 102 to rise, and transmits the signal to the control component 301; when the brake plate 102 returns, the sensing block 304b contacts the sensing rotary rod 304c on the lower side, triggering a signal for the brake plate 102 to fall.

[0048] Furthermore, the pressure sensor 301a, the rotation speed sensor 302a, the gap measurement sensor 303, and the sensor block 304b are all electrically connected to the control component 301.

[0049] When in use, by setting up a pressure sensor 301a, a speed sensor 302a, and a gap measurement sensor 303, the pressure on the brake plate 102, the gap between the brake plate 102 and the rotor, and the rotor speed are collected in real time, and the collected data is transmitted to the control component 301, which is processed and analyzed by the control component 301 to determine whether the brake plate 102 needs to be braked or reset, and the brake plate 102 is controlled to brake or reset by adjusting the height of the connecting rod 103a and the brake rod 104. The state acquisition component 304 is used to collect the state of the brake plate 102, whether it is in a raised or lowered state. When the brake plate 102 is in a braking state, but the state acquisition component 304 collects that the brake plate 102 is in a lowered state, the oil source is connected to raise the brake plate 102 for braking. On the contrary, the brake plate 102 can also be controlled to fall and reset.

[0050] In summary, by providing the monitoring component 300 , the state of the brake plate 102 , the pressure applied to the brake plate 102 , the gap between the brake plate 102 and the rotor, and the rotor speed can be monitored in real time.
