Description

Technical Field

[0001] This invention relates to the field of elevators, and in particular to a safety clamp braking assembly and its method of use. Background Technology

[0002] Safety clamps are an important safety component of elevator equipment, which can decelerate and stop the elevator in case of overspeed and loss of control. The operation of safety clamps is achieved by the action of the speed governor, which causes the rope clamp to clamp the speed governor rope. As the car moves downward, the speed governor rope pulls the safety clamp linkage mechanism, which drives the safety clamp braking element to contact the guide rail. This causes the safety clamps on both sides of the guide rail to squeeze and brake the outer wall of the elevator guide rail, thus bringing the elevator car to an emergency stop.

[0003] In common elevator safety clamps, when braking, the safety clamp linkage mechanism drives two brake blocks to move from both sides towards the center, pressing them against the sides of the elevator track. Due to the inertia of the elevator car, the car continues to move downwards, causing significant friction between the brake blocks and the track. The reaction force of this friction acts on the brake blocks, affecting their stability. Furthermore, after the brake blocks have pressed against the track, maintenance usually requires removing the safety clamp to release the pressure of the brake blocks and reset them. Disassembling the safety clamp is cumbersome and makes resetting the brake blocks inconvenient. Summary of the Invention

[0042] Preferably, the top of the locking tooth is inclined, the bottom of the locking block is inclined, the compression spring is disposed between the locking block and the movable block, the connecting groove is inclined, and one end of the groove is arc-shaped.

[0043] The present invention also provides a method for using the braking component of a safety clamp, including the following specific steps:

[0044] Step 1: First, by rotating the lifting rod upward, the rotating rod and connecting rod rotate together. The squeezing rod between the two connecting rods rotates upward, so that the squeezing rod squeezes the fixed tube. The fixed tube drives the fixed rod to move obliquely upward along the movable groove, which drives the two brake blocks to move together. The brake blocks move upward along the oblique surface of the fixed block, so that one side of the two brake blocks squeezes the two sides of the elevator track, thus playing a braking role.

[0045] Step 2: Then, by moving the brake block diagonally upward, the mounting block moves within the mounting groove. The top of the locking tooth presses against the bottom of the locking block, causing the locking block to slide into the inner cavity of the receiving groove. One end of the locking block is compressed and deformed by the compression spring, and the elasticity of the compression spring pushes the locking block outward, causing one end of the locking block to slide between an adjacent locking tooth, limiting the locking tooth and preventing the mounting block and brake block from moving downward. This provides limiting support for the brake block and ensures its stability.

[0046] Step 3: Next, by rotating the lifting rod downwards, the rotating rod and the fixed plate rotate together. The fixed plate rotates counterclockwise, and the bottom of the second fixed rod slides in the inner cavity of the groove. When the bottom of the second fixed rod moves to the arc-shaped position at one end of the groove, the arc-shaped inner wall of the groove presses the bottom of the second fixed rod to one side, causing the second fixed rod to move the connecting block to one side. The inner wall of the through groove on the connecting block pushes the movable rod, causing the movable rod to slide along the inner cavity of the connecting groove. The movable rod drives the movable block to one side, and the movable block drives multiple locking blocks to move together, causing one end of the locking block to separate from the locking teeth, releasing the limit on the mounting block and the brake block, allowing the brake block to slide downwards and reset.

[0047] The technical effects and advantages of this invention are as follows:

[0048] (1) The present invention utilizes a combination of brake block, mounting block, locking teeth, locking block and compression spring. The brake block moves obliquely upward, driving the mounting block to move in the inner cavity of the mounting groove. The top of the locking teeth presses against the bottom of the locking block, causing the locking block to slide into the inner cavity of the receiving groove. One end of the locking block is compressed and deformed by the compression spring, and the elasticity of the compression spring is used to push the locking block outward, so that one end of the locking block slides between the adjacent locking teeth, limiting the locking teeth and supporting the brake block, ensuring the stable braking of the elevator track by the brake block.

[0049] (2) The present invention utilizes a combination of a rotating rod, a fixed plate, a groove, a second fixed rod, a connecting block, a through groove, a movable rod, and a movable block. By rotating the lifting rod downwards, the rotating rod and the fixed plate rotate together. The fixed plate rotates counterclockwise, and the bottom of the second fixed rod slides in the inner cavity of the groove. When the bottom of the second fixed rod moves to the arc-shaped position at one end of the groove, the arc-shaped inner wall of the groove presses the bottom of the second fixed rod to one side, causing the second fixed rod to move the connecting block to one side. The inner wall of the through groove on the connecting block pushes the movable rod, causing the movable rod to slide along the inner cavity of the connecting groove. The movable rod moves the movable block to one side, and the movable block moves multiple locking blocks together, causing one end of the locking block to separate from the locking teeth, which facilitates the release of the limiting position on the mounting block and the brake block, and makes it convenient for the brake block to slide down and reset.

[0050] (3) The present invention utilizes a combination of a rotating rod, a connecting rod, a pressing rod, a fixed tube, a fixed rod one, a movable groove, a brake block, and a fixed block. By rotating the lifting rod upward, the rotating rod and the connecting rod rotate together. The pressing rod between the two connecting rods rotates upward, causing the pressing rod to press against the fixed tube. The fixed tube causes the fixed rod one to move obliquely upward along the movable groove, causing the two brake blocks to move together. The brake blocks move upward along the oblique surface of the fixed block, so that one side of the two brake blocks presses against both sides of the elevator track, thus achieving the braking effect.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] This invention provides, for example Figure 1-8 The safety clamp braking assembly shown includes a safety clamp mounting bracket 1, a brake block 2, a pressing mechanism 3, a support mechanism 4, and a reset mechanism 5. The safety clamp mounting bracket 1 is fixedly connected to the elevator car. The brake block 2 is disposed in the inner cavity of the safety clamp mounting bracket 1. The brake block 2 presses against the elevator track, and the frictional resistance and pressing force between the brake block 2 and the track brake the descending elevator. The pressing mechanism 3 is disposed on the safety clamp mounting bracket 1. The pressing mechanism 3 forms a clamping mechanism on the brake block 2 and drives the brake block 2 to move upward. The pressing mechanism 3 drives the two brake blocks to move upward. The car block 2 squeezes both sides of the elevator track to brake the elevator. The support mechanism 4 is set on the squeezing mechanism 3. The support mechanism 4 is used to form a limiting structure on the squeezing mechanism 3 and to limit and fix the squeezing mechanism 3. The support mechanism 4 supports and limits the squeezed brake block 2 to prevent the brake block 2 from loosening during the clamping process. The reset mechanism 5 is set between the squeezing mechanism 3 and the support mechanism 4. The reset mechanism 5 is used to form a moving structure on the support mechanism 4 and to release the limit on the brake block 2. The reset mechanism 5 facilitates the release of the fixation of the brake block 2, allowing the brake block 2 to slide down.

[0062] Furthermore, the extrusion mechanism 3 includes a fixed block 31, a fixed rod 32, a movable groove 33, a fixed tube 34, a rotating rod 35, a connecting rod 36, an extrusion rod 37, and a lifting rod 38. The upper surface of the fixed block 31 is fixedly connected to the top of the inner wall of the safety clamp fixing frame 1. One side of the fixed block 31 is inclined. The fixed block 31 is used to extrude the brake block 2 to ensure the stable movement of the brake block 2 in the inclined direction. One end of the fixed rod 32 is fixedly inserted into the brake block 2. The fixed rod 32 is used to drive the brake block 2 to move. The groove 33 is located on the back of the inner wall of the safety clamp fixing frame 1. The inner cavity of the movable groove 33 is slidably inserted into the other end of the fixed rod 32. The movable groove 33 is used to ensure that the brake block 2 moves in an oblique direction. The fixed rod 32 moves along the inner cavity of the movable groove 33. The fixed tube 34 is fixedly inserted into the other end of the fixed rod 32. The fixed tube 34 is used to drive the fixed rod 32 and the brake block 2 to move. The two ends of the rotating rod 35 are rotatably inserted into the two sides of the safety clamp fixing frame 1. The rotating rod 35 is used to drive the compression rod 37 and the fixed rod 32 to move. The disc 57 rotates, and one end of the connecting rod 36 is fixedly connected to the outer wall of one end of the rotating rod 35. Two connecting rods 36 are symmetrically fixed at both ends of the rotating rod 35, arranged at an angle, for fixing the pressing rod 37. One end of the pressing rod 37 is fixedly inserted into the other end of the connecting rod 36. The outer wall of the pressing rod 37 is in contact with the bottom of the outer wall of the fixed tube 34. The pressing rod 37 is positioned below the two fixed tubes 34 and is used to press the two fixed tubes 34 upwards. One end of the lifting rod 38 is fixedly connected to one end of the rotating rod 35. One end of the lifting rod 38... The end is inclined downwards and is used to rotate the rotating rod 35. By rotating the lifting rod 38 upwards, the rotating rod 35 and the connecting rod 36 are driven to rotate together. The pressing rod 37 between the two connecting rods 36 rotates upwards, so that the pressing rod 37 presses the fixed tube 34. The fixed tube 34 drives the fixed rod 32 to move obliquely upwards along the movable groove 33, which drives the two brake blocks 2 to move together. The brake blocks 2 move upwards along the inclined surface of the fixed block 31, so that one side of the two brake blocks 2 presses against both sides of the elevator track, thus playing a braking role.

[0063] Specifically, the support mechanism 4 includes a mounting block 41, locking teeth 42, mounting groove 43, locking block 44, receiving groove 45, movable block 46, mounting rod 47, compression spring 48, and limiting block 49. The mounting block 41 is fixedly connected to one side of the outer wall of the brake block 2, and the mounting block 41 moves together with the brake block 2. The locking teeth 42 are arranged in a straight line on one side of the mounting block 41, and multiple locking teeth 42 are provided on the mounting block 41. The mounting groove 43 is provided on one side of the outer wall of the fixed block 31, and the inner cavity of the mounting groove 43 is slidably inserted into the mounting block 41. The mounting groove 43 is used to receive... The mounting block 41 and the locking block 44 are installed. One end of the locking block 44 is slidably inserted into one side of the inner wall of the mounting groove 43. Multiple locking blocks 44 are equidistantly arranged in the inner cavity of the mounting groove 43. The bottom of the outer wall of the lowermost locking block 44 is in contact with the outer wall of the uppermost locking tooth 42, which exerts a downward pressing effect on the mounting block 41 and the brake block 2 to ensure the stability of the brake block 2. The receiving groove 45 is set on the other side of the fixed block 31. The movable block 46 is slidably inserted into the inner cavity of the receiving groove 45. The movable block 46 is used to install multiple locking blocks 44 and the mounting rod 47, and to drive multiple locking blocks 44. 4. Moving together, one end of the mounting rod 47 is fixedly connected to the other end of the locking block 44, and the other end of the mounting rod 47 is slidably connected to the movable block 46. The compression spring 48 is movably sleeved with the other end of the mounting rod 47. When the locking tooth 42 moves upward, it squeezes the locking block 44, causing one end of the locking block 44 to compress and deform against the compression spring 48. The limiting block 49 is fixedly connected to the other end of the mounting rod 47. The limiting block 49 is used to prevent the mounting rod 47 from separating from the movable block 46, and to facilitate the movable block 46 to pull the mounting rod 47 and the locking block 44 to one side, through the brake block 2. The device moves diagonally upwards, causing the mounting block 41 to move within the inner cavity of the mounting groove 43. The top of the locking tooth 42 presses against the bottom of the locking block 44, causing the locking block 44 to slide into the inner cavity of the receiving groove 45. One end of the locking block 44 is compressed and deformed by the compression spring 48, and the elasticity of the compression spring 48 pushes the locking block 44 outwards, causing one end of the locking block 44 to slide and insert between the adjacent locking tooth 42, limiting the locking tooth 42 and preventing the mounting block 41 and brake block 2 from moving downwards. This provides limiting support for the brake block 2 and ensures its stability.

[0064] Furthermore, the reset mechanism 5 includes a connecting groove 51, a movable rod 52, a connecting block 53, a through groove 54, a fixed rod 55, a sliding rod 56, a fixed plate 57, and a groove 58. The connecting groove 51 is located on the back side of the inner wall of the mounting groove 43 and is used to install the movable rod 52. One end of the movable rod 52 is fixedly connected to the middle of the back side of the movable block 46, and the other end of the movable rod 52 is slidably inserted into the inner cavity of the connecting groove 51. The movable rod 52 is used to drive the movable block 46 to move. The movable rod 52 slides along the inner cavity of the connecting groove 51 and moves obliquely along the inner cavity of the connecting groove 51. The connecting block 53 is located at the other end of the movable rod 52 and moves horizontally. Block 53 is used to move one end of the movable rod 52. A through groove 54 is provided on the connecting block 53, and the inner cavity of the through groove 54 is slidably inserted into the other end of the movable rod 52. The through groove 54 is used to install the movable rod 52, and the inner wall of the through groove 54 presses against one end of the movable rod 52 to ensure the vertical movement of the movable rod 52. The top end of the second fixed rod 55 is fixedly connected to the lower surface of the connecting block 53. The second fixed rod 55 is used to drive the connecting block 53 to move horizontally. The sliding rod 56 is slidably inserted into the middle of the second fixed rod 55, and both ends of the sliding rod 56 are fixedly connected to the inner wall of the safety clamp fixing frame 1. The second fixed rod 55 moves along the sliding rod 56 to ensure stable movement of the second fixed rod 55. The middle part of the fixed plate 57 is fixedly inserted and connected to one end of the rotating rod 35. The fixed plate 57 is located below the second fixed rod 55. The fixed plate 57 rotates together with the rotating rod 35. As the fixed plate 57 rotates, it drives the second fixed rod 55 to move. The groove 58 is provided on the outer wall of the fixed plate 57. The inner cavity of the groove 58 is slidably inserted and connected to the bottom of the second fixed rod 55. As the fixed plate 57 rotates, the bottom of the second fixed rod 55 slides in the inner cavity of the groove 58, and the inner wall of the groove 58 presses against the bottom of the second fixed rod 55, causing the second fixed rod 55 to drive the connecting block 53 to move in the horizontal direction. By rotating the lifting rod 38 downward, the rotating rod 35 and the fixed plate 57 rotate together. When the fixed plate 57 rotates counterclockwise, the bottom of the fixed rod 55 slides in the inner cavity of the groove 58. When the bottom of the fixed rod 55 moves to the arc-shaped position at one end of the groove 58, the arc-shaped inner wall of the groove 58 presses the bottom of the fixed rod 55 to one side, causing the fixed rod 55 to drive the connecting block 53 to move to one side. The inner wall of the through groove 54 on the connecting block 53 pushes the movable rod 52, causing the movable rod 52 to slide along the inner cavity of the connecting groove 51. The movable rod 52 drives the movable block 46 to move to one side. The movable block 46 drives multiple locking blocks 44 to move together, causing one end of the locking block 44 to separate from the locking tooth 42, releasing the limit on the mounting block 41 and the brake block 2, allowing the brake block 2 to slide downward and reset.

[0065] One side of the brake block 2 is inclined, and the inclined surface of the brake block 2 is in contact with the inclined surface of the fixed block 31. The movable groove 33 is inclined. Both ends of the fixed tube 34 are in contact with the inner wall of the safety clamp fixing frame 1. The top of the locking tooth 42 is inclined, the bottom of the locking block 44 is inclined, the compression spring 48 is located between the locking block 44 and the movable block 46, the connecting groove 51 is inclined, and one end of the groove 58 is arc-shaped.

[0066] How to use this invention:

[0067] First, by rotating the lifting rod 38 upward, the rotating rod 35 and the connecting rod 36 are rotated together. The pressing rod 37 between the two connecting rods 36 rotates upward, so that the pressing rod 37 presses against the fixed tube 34. The fixed tube 34 drives the fixed rod 32 to move obliquely upward along the movable groove 33, which in turn drives the two brake blocks 2 to move together. The brake blocks 2 move upward along the oblique surface of the fixed block 31, so that one side of the two brake blocks 2 presses against both sides of the elevator track, thus playing a braking role.

[0068] Then, by moving the brake block 2 obliquely upward, the mounting block 41 moves in the inner cavity of the mounting groove 43. The top of the locking tooth 42 presses against the bottom of the locking block 44, causing the locking block 44 to slide into the inner cavity of the receiving groove 45. One end of the locking block 44 is compressed and deformed by the compression spring 48, and the elasticity of the compression spring 48 is used to push the locking block 44 outward, so that one end of the locking block 44 slides and inserts between the adjacent locking tooth 42, limiting the locking tooth 42, so that the mounting block 41 and the brake block 2 cannot move downward, limiting and supporting the brake block 2, and ensuring the stability of the brake block 2.

[0069] Next, by rotating the lifting rod 38 downwards, the rotating rod 35 and the fixed plate 57 are rotated together. The fixed plate 57 rotates counterclockwise, and the bottom of the second fixed rod 55 slides in the inner cavity of the groove 58. When the bottom of the second fixed rod 55 moves to the arc-shaped position at one end of the groove 58, the arc-shaped inner wall of the groove 58 presses the bottom of the second fixed rod 55 to one side, causing the second fixed rod 55 to move the connecting block 53 to one side. The inner wall of the through groove 54 on the connecting block 53 pushes the movable rod 52, causing the movable rod 52 to slide along the inner cavity of the connecting groove 51. The movable rod 52 causes the movable block 46 to move to one side, and the movable block 46 causes multiple locking blocks 44 to move together, causing one end of the locking block 44 to separate from the locking tooth 42, releasing the limit on the mounting block 41 and the brake block 2, and causing the brake block 2 to slide downwards and reset.

[0070] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

The movable groove (33) is set at an angle, and the two ends of the fixed tube (34) are in contact with the inner wall of the safety clamp fixing frame (1).

3. The braking assembly of a safety clamp according to claim 2, characterized in that, The top of the locking tooth (42) is inclined, the bottom of the locking block (44) is inclined, the compression spring (48) is disposed between the locking block (44) and the movable block (46), the connecting groove (51) is inclined, and one end of the groove (58) is arc-shaped.

4. A method of using a braking assembly of a safety clamp, characterized in that, The specific usage steps are as follows: Step 1: First, by rotating the lifting rod (38) upward, the rotating rod (35) and the connecting rod (36) rotate together. The squeezing rod (37) between the two connecting rods (36) rotates upward, so that the squeezing rod (37) squeezes the fixed tube (34). The fixed tube (34) drives the fixed rod (32) to move obliquely upward along the movable groove (33), which drives the two brake blocks (2) to move together. The brake blocks (2) move upward along the oblique surface of the fixed block (31), so that one side of the two brake blocks (2) squeezes the two sides of the elevator track, which plays a braking role. Step 2: Then, by moving the brake block (2) obliquely upward, the mounting block (41) moves in the inner cavity of the mounting groove (43). The top of the tooth (42) presses the bottom of the block (44), causing the block (44) to slide into the inner cavity of the receiving groove (45). One end of the block (44) is compressed and deformed by the spring (48), and the elasticity of the spring (48) is used to push the block (44) outward, so that one end of the block (44) slides and inserts between the adjacent tooth (42), limiting the tooth (42), so that the mounting block (41) and the brake block (2) cannot move downward, limiting and supporting the brake block (2), and ensuring the stability of the brake block (2). Step 3: Next, by rotating the lifting rod (38) downwards, the rotating rod (35) and the fixed plate (57) rotate together. The fixed plate (57) rotates counterclockwise, and the bottom of the second fixed rod (55) slides in the inner cavity of the groove (58). When the bottom of the second fixed rod (55) moves to the arc-shaped position at one end of the groove (58), the arc-shaped inner wall of the groove (58) presses the bottom of the second fixed rod (55) to one side, so that the second fixed rod (55) drives the connecting block (53). Move to one side, the inner wall of the through groove (54) on the connecting block (53) pushes the movable rod (52), so that the movable rod (52) slides along the inner cavity of the connecting groove (51). The movable rod (52) drives the movable block (46) to move to one side, and the movable block (46) drives multiple locking blocks (44) to move together, so that one end of the locking block (44) separates from the locking tooth (42), releasing the limit on the mounting block (41) and the brake block (2), so that the brake block (2) slides down to reset.
