Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a brake system for an elevator. Background Art

[0002] The elevator brake is the final actuator of the elevator's safety system and one of its most critical components. Braking and maintaining an elevator stationary in emergency situations rely on the brake. An electromagnetic control device controls the brake pads to fit against the brake hub, locking the hub and achieving braking.

[0003] The commonly used electromagnetic brake compresses the spring to press the brake pad against the brake hub to achieve elevator braking. However, during the process of the brake pad braking the elevator, the brake hub continues to rotate. When the rotating brake hub contacts the brake pad, it will cause wear on the brake hub and brake pad. The wear of the brake hub will affect the subsequent braking effect. If the elevator is not locked and fixed in time, it will cause safety hazards. Therefore, we have proposed a brake system for elevators. Utility Model Content

[0004] In response to the shortcomings of the existing holding brake system for elevators, the utility model provides a holding brake system for elevators, which has the advantages that when the brake hub is locked by the locking arm, the auxiliary roller initially locks the position of the brake hub, and at the same time the connecting plate drives the brake pad to be clamped and installed inside the locking arm, thereby reducing the wear of the brake pad. At the same time, when the brake pad is damaged, it is convenient to replace the damaged brake pad, thereby solving the problems raised in the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a holding brake system for an elevator, comprising a first base, an internal movably sleeved second base on one side of the first base, lower portions of side surfaces of the first and second bases are fixedly connected to support feet, an upper portion of the first base is hingedly provided with a vertical rod, an internal movably sleeved connecting sleeve at the upper end of the vertical rod, a group of mounting columns passing through the interior of the connecting sleeves, one end of the mounting column is fixedly connected to an electromagnetic controller, a control column is installed internally on one side of the electromagnetic controller, a first spring is sleeved on the exterior of the control column, an arc-shaped holding arm is installed on the inner side of the middle portion of the vertical rod, and a brake hub is clamped and installed on the inner side of the holding arm.

[0006] Preferably, support plates are installed on the upper parts of the first base and the second base and on both sides of the vertical rod, wherein spring steel is installed between the connection between the support plates and the first base.

[0007] Preferably, a guide groove is provided inside the first base, and both sides of the second base are movably sleeved inside the guide groove. Positioning holes are provided inside the first base and the second base, and positioning pins are installed inside the positioning holes.

[0009] Preferably, an electromagnet is installed inside the electromagnetic controller, and an electromagnetic control device is installed on the side of the electromagnet.

[0010] Preferably, a second spring is installed between the vertical rod and the locking arm, an auxiliary roller is installed inside the locking arm through the spring, and the inner side of the auxiliary roller contacts the outer wall of the brake hub.

[0011] Preferably, a brake pad is installed on the inner side of the locking arm through a connecting plate, and an anti-slip groove is provided on the inner side of the brake pad.

[0012] Compared with the existing brake system for elevators, the utility model has the following beneficial effects:

[0013] 1. The holding brake system for elevators adjusts the position of the second base inside the first base and installs a positioning pin inside the positioning hole. That is, the positioning pin drives the position between the first base and the second base to be spliced and limited. At the same time, the nut is rotated, and the nut drives the position of the control column to be limited. That is, the vertical rod can move inward. At this point, the brake hub can be locked according to different diameters of the brake hub.

[0014] 2. The holding brake system for elevators is equipped with an auxiliary roller installed on the inner side of the holding arm. When the holding arm is controlled to lock and fix the brake hub, the holding arm drives the auxiliary roller to initially contact the brake hub. After the auxiliary roller contacts the brake hub, the rotation speed of the brake hub can be slowed down. At the same time, the brake pad is controlled to contact the brake hub, so that the position of the brake hub can be locked. When the brake pad is worn after being locked, the connecting plate can be removed to drive the brake pad out from the inside of the holding arm, thereby improving the convenience of its maintenance and replacement.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 A holding brake system for an elevator includes a first base 1, a second base 2 is movably sleeved on one side of the first base 1, and the position between the first base 1 and the second base 2 is adjusted, that is, the position of the second base 2 inside the first base 1 is limited. The lower parts of the sides of the first base 1 and the second base 2 are fixedly connected with support legs 4. A fastening device is installed inside the support legs 4, and the fastening device can drive the first base 1 and the second base 2 to limit the position above the ground. A vertical rod 5 is installed on the upper part of the first base 1 through a hinge, and a connecting sleeve 6 is movably sleeved on the upper end of the vertical rod 5. The connecting sleeve 6 It is arranged inside the vertical rod 5, and the angle of the connecting sleeve 6 inside the vertical rod 5 can be adjusted. A mounting column 7 is passed through the interior of a group of connecting sleeves 6, and one end of the mounting column 7 is fixedly connected to an electromagnetic controller 8. A control column 10 is installed inside one side of the electromagnetic controller 8, and a first spring 11 is installed on the outer sleeve of the control column 10. When the equipment stops locking, the first spring 11 can push the vertical rod 5 to move to both sides. An arc-shaped locking arm 13 is installed on the inner side of the middle of the vertical rod 5, and a brake hub 18 is clamped and installed on the inner side of the locking arm 13. The locking arm 13 is controlled to extend inward, and the locking arm 13 locks the position of the brake hub 18.

[0023] Among them, support plates 19 are installed on the upper part of the first base 1 and the second base 2 and on both sides of the vertical rod 5, wherein spring steel is installed between the support plate 19 and the connection between the first base 1. By installing support plates 19 on the upper part of the first base 1 and the second base 2, wherein the support plates 19 are arranged on both sides of the vertical rod 5, the support plates 19 limit the moving trajectory of the vertical rod 5 to prevent the vertical rod 5 from deviating to both sides. At the same time, when the control device locks the brake hub 18, the vertical rod 5 moves inward, and the spring steel installed inside the support plate 19 is deviated, which provides a moving space for clamping the vertical rod 5.

[0024] Among them, a guide groove is opened inside the first base 1, and both sides of the second base 2 are movably sleeved inside the guide groove. Positioning holes 3 are opened inside the first base 1 and the second base 2, and positioning pins are installed inside the positioning holes 3. By opening a guide groove inside the first base 1 and movably sleeved inside the guide groove, the position of the second base 2 inside the first base 1 can be adjusted according to the diameter of the brake hub 18. At the same time, the positioning pin is used to pass through the inside of the positioning hole 3, that is, the position between the first base 1 and the second base 2 is controlled to be spliced and limited, that is, the cover brake equipment can lock and fix the brake hub 18 according to different equipment models.

[0025] Among them, the control column 10 passes through the interior of another set of connecting sleeves 6, and the first spring 11 is installed between the other set of connecting sleeves 6 and the electromagnetic controller 8. The external thread on the other side of the control column 10 is installed with a nut 12, which passes through the interior of the other set of connecting sleeves 6 through the mounting column 7 and tightens the nut 12 at the same time, that is, the mounting column 7 is controlled to extend to the outside of the other set of connecting sleeves 6, and the length of the mounting column 7 is adjusted at the same time. At this point, the distance between the upper ends of the two sets of vertical rods 5 can be controlled. At the same time, a first spring 11 is installed between the connecting sleeves 6 and the electromagnetic controller 8. Under normal conditions, the first spring 11 pushes the electromagnetic controller 8 to move sideways to prevent the locking arm 13 from locking the brake hub 18.

[0026] Among them, an electromagnet 9 is installed inside the electromagnetic controller 8, and an electromagnetic control device is installed on the side of the electromagnet 9. The electromagnet 9 is installed inside the electromagnetic controller 8, and the electromagnetic control device is started at the same time. The electromagnet 9 generates magnetic force, and the magnetic force adsorbs the first spring 11. At the same time, the upper end of the vertical rod 5 contracts inward, controlling the locking arm 13 to squeeze and limit the brake hub 18, thereby locking and fixing the brake hub 18.

[0027] Among them, a second spring 14 is installed between the vertical rod 5 and the locking arm 13, and an auxiliary roller 15 is installed inside the locking arm 13 through a spring. The inner side of the auxiliary roller 15 contacts the outer wall of the brake hub 18. The auxiliary roller 15 is installed on the inner side of the locking arm 13 to control the contact between the auxiliary roller 15 and the outside of the brake hub 18. At the same time, when the locking arm 13 moves inward, the auxiliary roller 15 first contacts the brake hub 18. At the same time, under the action of the rolling of the auxiliary roller 15, the rotation speed of the brake hub 18 is initially reduced to avoid the brake hub 18 from rotating too fast, resulting in wear on the contact surface between the brake pad 17 and the brake hub 18. At the same time, the second spring 14 is arranged between the vertical rod 5 and the locking arm 13, and the second spring 14 pushes the locking arm 13 to move to a centered state.

[0028] Among them, a brake pad 17 is installed on the inner side of the locking arm 13 through a connecting plate 16. An anti-slip groove is opened on the inner side of the brake pad 17. A connecting plate 16 is installed on the inner side of the locking arm 13. The connecting plate 16 drives the brake pad 17 to extend to the inner side of the locking arm 13. The brake pad 17 is prone to wear during use. At this time, by removing the connecting plate 16 from the side of the locking arm 13, the brake pad 17 can be easily replaced, thereby improving the convenience of equipment maintenance.

[0029] Working principle: When in use, the first base 1 is set on the inner side of the brake hub 18, and the position between the first base 1 and the second base 2 is adjusted according to the different diameters of the brake hub 18. At the same time, the internal mounting screws of the support foot 4 improve the stability of the first base 1 and the second base 2 when the positions are limited. At the same time, the nut 12 is rotated to control the upper end of the vertical rod 5 to extend inward. When it is necessary to control the equipment to lock, the electromagnetic control device installed inside the electromagnetic controller 8 is started, that is, the electromagnet 9 generates magnetic force, and the electromagnet 9 adsorbs the control column 10. At the same time, the locking arm 13 extends inward, and the locking arm 13 drives the brake pad 17 to contact the outside of the brake hub 18. The brake pad 17 locks the position of the brake hub 18, and when the brake pad 17 contacts the brake hub 18, the auxiliary roller 15 contacts the brake hub 18 in advance, which preliminarily reduces the rotation speed of the brake hub 18 to avoid the brake hub 18 rotating too fast when locking, causing damage to it. At this point, the position of the brake hub 18 can be locked.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
