Description

Technical Field

[0001] This utility model specifically relates to the field of elevator traction machine technology, and more specifically to a permanent magnet synchronous traction machine for elevators. Background Technology

[0002] The permanent magnet synchronous traction machine for elevators is the power unit of the elevator. It mainly consists of a permanent magnet synchronous motor, traction sheave, braking system, bearings and encoder. The permanent magnet synchronous traction machine is driven by a permanent magnet synchronous motor. After three-phase alternating current is applied to the stator winding, a rotating magnetic field is generated. This magnetic field interacts with the rotor permanent magnet, causing the rotor to rotate synchronously with the rotating magnetic field, which in turn drives the coaxial traction sheave to rotate. Through the friction between the traction rope and the traction sheave, the elevator car and counterweight are pulled up and down.

[0003] However, in practice, it has been noted that most traditional traction machine brakes rely on disc brakes, using the friction between the brake and the disc for braking. When a malfunction occurs during operation, the cable can easily slip or detach from the inside of the traction sheave. In this case, simply braking the traction sheave cannot guarantee passenger safety, resulting in weak direct protection for the cable on the traction sheave. In emergency scenarios where the cable falls rapidly, the locking force and contact area of ​​a single braking structure are limited, making it difficult to brake the cable quickly and stably, which can easily lead to safety accidents. Utility Model Content

[0004] The purpose of this invention is to provide a permanent magnet synchronous traction machine for elevators. It utilizes the clamps on both sides of the brake disc to move the connecting rod. When the symmetrical clamps retract, they grip the brake disc, simultaneously causing the piston rods at both ends of the oil reservoir to retract inwards. At the same time, hydraulic oil from the inside of the oil reservoir flows into the hydraulic cylinder through the oil pipe, thereby pushing the tilting locking block towards the anti-slip fixing block, locking the cable passing through the middle, and preventing the cable from slipping above the traction sheave. This solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A permanent magnet synchronous traction machine for elevators includes a permanent magnet synchronous motor. One end of the permanent magnet synchronous motor is fixedly connected to a brake disc and a traction sheave, while both sides of the brake disc are provided with brake calipers that are movably connected to the permanent magnet synchronous motor.

[0007] The two brake calipers are also movably connected to the top side of the caliper. Each brake caliper has an arc-shaped caliper claw, and the side of the caliper claw is integrally provided with an extended connecting post corresponding to the hydraulic trigger.

[0008] As a further technical solution of this utility model, the hydraulic trigger has an oil reservoir containing hydraulic oil, and both ends of the oil reservoir are slidably fitted with piston rods. The end of each piston rod passes through the oil reservoir and is fixedly connected to a connecting rod by a threaded adjusting rod.

[0009] As a further technical solution of this utility model, the threads at both ends of the threaded adjusting rod have opposite directions of rotation, and the two ends of the threaded adjusting rod are respectively threadedly engaged with the piston rod and the connecting rod.

[0010] As a further technical solution of this utility model, the end of the connecting rod away from the threaded adjusting rod is sleeved on the outside of the extended connecting post, and the end of the extended connecting post is also fitted with an elastic limiting pin to prevent the connecting rod from falling off.

[0011] As a further technical solution of this utility model, an oil outlet is fixedly connected to the side of the oil storage cylinder, and is connected to the swing brake through an oil pipe sleeved at the other end of the oil outlet.

[0012] As a further technical solution of this utility model, the swing brake has a flipping locking block movably connected above the fixed mounting base. One end of the flipping locking block is symmetrically and movably connected to a connecting bushing, and a hydraulic cylinder is fixedly connected to the side of each connecting bushing.

[0013] As a further technical solution of this utility model, the fixed mounting base has a base body fixedly connected to the side of the permanent magnet synchronous motor, an inclined support base connected to the flipping locking block is provided on the upper part of the base body, and a rotating groove corresponding to the inclined support base is provided at the bottom of the flipping locking block.

[0014] As a further technical solution of this utility model, the inclined support seat is inserted into the rotating groove, and the inclined support seat is also interference-fitted with a support shaft, and both ends of the support shaft are movably connected to the flip locking block.

[0015] As a further technical solution of this utility model, a fixed friction device corresponding to the flip-locking block is fixedly connected above the end of the seat away from the flip-locking block. The fixed friction device has an anti-slip fixing block, which is fixedly connected to the seat through a mounting bolt that passes through the side. The end of the mounting bolt is threaded into the seat.

[0016] As a further technical solution of this utility model, the bottom of the anti-slip fixing block is also provided with a limiting slot, and the base is integrally provided with a dovetail slide rail corresponding to the limiting slot, and the dovetail slide rail is inserted and matched with the limiting slot.

[0017] As a further technical solution of this utility model, the anti-slip fixing block is provided with a braking groove on the side near the flip locking block, and the side of the flip locking block is integrally provided with a matching protrusion corresponding to the braking groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. In this utility model, the symmetrical jaws swing inward, pushing the friction brake blocks on both sides of the brake disc to retract inward, thereby clamping the brake disc. At the same time, the jaws drive the connecting rod to move through the extended connecting post integrally set on the side, thereby pushing the piston rods on both sides of the oil reservoir to retract inward, thus compressing the space inside the oil reservoir. The hydraulic oil inside the oil reservoir flows into the swing brake through the oil pipe, thereby causing the swing brake to move closer to the fixed friction device, locking the cable on the traction sheave, preventing the cable from sliding from the inside of the traction sheave due to a fault, thereby improving the protection effect of the cable.

[0020] 2. In this utility model, hydraulic oil inside the oil storage cylinder enters the inner side of the hydraulic cylinder through an oil pipe, thereby pushing the output rod of the hydraulic cylinder to move outward. Then, through the rotational engagement between the connecting bushing at the end of the hydraulic cylinder output rod and the tilting locking block, the tilting locking block moves closer to the anti-slip fixing block. Finally, through the mutual engagement of the protrusion and the braking groove, the contact area between the tilting locking block and the anti-slip fixing block is increased, thereby locking the rapidly falling cable and further improving the safety of the traction machine during use.

[0021] 3. In this utility model, when replacing the anti-slip fixing block, the mounting bolts on the side need to be removed first, then the block is moved forward to remove and replace it. The new anti-slip fixing block is then reinstalled onto the base, and the limiting slot below the anti-slip fixing block corresponds to the dovetail slide rail at one end of the base. The anti-slip fixing block is then pushed to install it in the designated position. Finally, the end of the mounting bolt is inserted through the anti-slip fixing block and fixedly connected to the base, thus facilitating the quick replacement of the fixed friction device.

[0022] 4. In this utility model, a wrench is inserted into the outer side of the adjustment plane on the outside of the threaded adjustment rod, and then the threaded adjustment rod is rotated using the wrench. Since the threaded adjustment rod adopts a compound thread with opposite directions of rotation at both ends, the piston rod and the connecting rod are moved in opposite directions through the threaded engagement between the two ends of the threaded adjustment rod and the piston rod and the connecting rod, thereby increasing or decreasing the distance between the piston rod and the connecting rod, and thus adjusting the position of the end of the connecting rod.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-10 This utility model provides a permanent magnet synchronous traction machine for elevators, including a permanent magnet synchronous motor 1. One end of the permanent magnet synchronous motor 1 is fixedly connected to a brake disc 3 and a traction sheave 2. The rotor inside the permanent magnet synchronous motor 1 can drive the brake disc 3 and the traction sheave 2 to rotate synchronously, thereby pulling the cable. Both sides of the brake disc 3 are provided with brake calipers 4 that are movably connected to the permanent magnet synchronous motor 1, and the brake calipers 4 on both sides are symmetrically arranged to brake using friction.

[0037] The top sides of the two brake calipers 4 are also movably connected to hydraulic triggers 6. Each brake caliper 4 has an arc-shaped caliper claw 41. The side of the caliper claw 41 is integrally provided with an extended connecting post 42 corresponding to the hydraulic trigger 6. The cross-section of the extended connecting post 42 is stepped, and the axial positioning effect can be achieved by changing the shaft diameter.

[0038] The hydraulic trigger 6 has an oil reservoir 61 containing hydraulic oil, and piston rods 63 are slidably fitted at both ends of the oil reservoir 61. One end of the piston rod 63 is located inside the oil reservoir 61, and the hydraulic oil inside the oil reservoir 61 is located between the two piston rods 63. The end of each piston rod 63 passes through the oil reservoir 61 and is fixedly connected to a connecting rod 64 by a threaded adjusting rod 65.

[0039] Furthermore, a piston is fixedly connected to the end of the piston rod 63 away from the connecting rod 64, and the piston slides inside the oil reservoir 61. At the same time, the hydraulic oil inside the oil reservoir 61 is located between two symmetrically arranged pistons.

[0040] More specifically, the threads at both ends of the threaded adjusting rod 65 have opposite directions of rotation, and the two ends of the threaded adjusting rod 65 are respectively threaded into the piston rod 63 and the connecting rod 64;

[0041] The end of the connecting rod 64 away from the threaded adjusting rod 65 is sleeved on the outside of the extended connecting post 42, and the end of the extended connecting post 42 is also fitted with an elastic limiting pin 46 to prevent the connecting rod 64 from falling off.

[0042] By adopting the above technical solution, the wrench is inserted into the outer side of the adjustment plane of the threaded adjusting rod 65, and then the threaded adjusting rod 65 is rotated using the wrench. Since the threaded adjusting rod 65 adopts a compound thread with opposite directions of rotation at both ends, the piston rod 63 and the connecting rod 64 are moved in opposite directions through the threaded engagement between the two ends of the threaded adjusting rod 65 and the piston rod 63 and the connecting rod 64, respectively, thereby increasing or decreasing the distance between the piston rod 63 and the connecting rod 64, and thus adjusting the position of the end of the connecting rod 64.

[0043] Furthermore, an oil outlet 62 is fixedly connected to the side of the oil storage cylinder 61, and is connected to the swing brake 9 through an oil pipe 10 sleeved at the other end of the oil outlet 62.

[0044] The swing brake 9 has a flip locking block 91 that is movably connected to the fixed mounting base 7. One end of the flip locking block 91 is symmetrically and movably connected to a connecting bushing 92. Each connecting bushing 92 is fixedly connected to a hydraulic cylinder 93 on its side.

[0045] Furthermore, the fixed mounting base 7 has a base body 71 fixedly connected to the side of the permanent magnet synchronous motor 1, an inclined support base 74 connected to the flip locking block 91 is provided above the base body 71, and a rotating groove 95 corresponding to the inclined support base 74 is provided at the bottom of the flip locking block 91.

[0046] The inclined support 74 is inserted into the rotating groove 95, and the inclined support 74 is also interference-fitted with a support shaft 741, and both ends of the support shaft 741 are movably connected to the flip locking block 91.

[0047] By adopting the above technical solution, when replacing the anti-slip fixing block 81, it is necessary to first remove the mounting bolt 83 on the side, then move it forward to remove the anti-slip fixing block 81 for replacement, and reinstall the new anti-slip fixing block 81 onto the base 71. The limiting slot 84 below the anti-slip fixing block 81 corresponds to the dovetail slide rail 76 at one end of the base 71. Push the anti-slip fixing block 81 to install it in the designated position. Finally, the end of the mounting bolt 83 passes through the anti-slip fixing block 81 and is fixedly connected to the base 71, thereby facilitating the quick replacement of the fixed friction device 8.

[0048] More specifically, a fixed friction device 8 corresponding to the flip-locking block 91 is fixedly connected above the end of the seat 71 away from the flip-locking block 91. The fixed friction device 8 has an anti-slip fixing block 81, which is fixedly connected to the seat 71 by a mounting bolt 83 that passes through the side. The end of the mounting bolt 83 is threaded into the seat 71.

[0049] Furthermore, the bottom of the anti-slip fixing block 81 is provided with a limiting slot 84, and the base 71 is integrally provided with a dovetail slide rail 76 corresponding to the limiting slot 84, and the dovetail slide rail 76 is inserted and engaged with the limiting slot 84.

[0050] Furthermore, the anti-slip fixing block 81 is provided with a braking groove 82 on the side near the flip locking block 91, and the side of the flip locking block 91 is integrally provided with a matching protrusion 94 corresponding to the braking groove 82.

[0051] By adopting the above technical solution, the hydraulic oil inside the oil storage cylinder 61 enters the inner side of the hydraulic cylinder 93 through the oil pipe 10, thereby pushing the output rod of the hydraulic cylinder 93 to move outward. Then, through the rotational engagement between the connecting bushing 92 at the end of the output rod of the hydraulic cylinder 93 and the tilting locking block 91, the tilting locking block 91 moves closer to the anti-slip fixing block 81. Finally, through the mutual engagement of the protrusion 94 and the brake groove 82, the contact area between the tilting locking block 91 and the anti-slip fixing block 81 is increased, thereby locking the rapidly falling cable and further improving the safety of the traction machine during use.

[0052] Furthermore, the seat 71 is provided with a rope groove 72 located between the anti-slip fixing block 81 and the flip locking block 91, and the inner side of the rope groove 72 is symmetrically and movably connected with guide rollers 73. The outer side of each guide roller 73 is provided with an arc-shaped guide groove 731 in a rectangular array.

[0053] More specifically, each of the aforementioned caliper claws 41 is movably connected to a friction brake block 43 on the side near the brake disc 3. When the caliper claws 41 retract inward, they push the friction brake block 43 to clamp the brake disc 3, and braking is achieved through the friction between the friction brake block 43 and the brake disc 3.

[0054] Furthermore, a limiting post 44 is inserted and fitted above the jaw 41. One end of the limiting post 44 is fixedly connected to the platform fixing seat 11 above the permanent magnet synchronous motor 1, and the other end is fitted with a locking spring 45. The end of the locking spring 45 is attached to the side of the jaw 41 away from the brake disc 3. When the electromagnetic starter 5 is de-energized, the locking spring 45 pushes the jaw 41 to move through its own elasticity, so that the jaw 41 locks the brake disc 3.

[0055] By adopting the above technical solution, the symmetrical caliper 41 swings inward, pushing the friction brake blocks 43 on both sides of the brake disc 3 to retract inward, thereby clamping the brake disc 3. At the same time, the caliper 41 drives the connecting rod 64 to move through the extended connecting post 42 integrally set on the side, thereby pushing the piston rod 63 on both sides of the oil reservoir 61 to retract inward, thereby compressing the space inside the oil reservoir 61. The hydraulic oil inside the oil reservoir 61 flows into the swing brake 9 through the oil pipe 10, thereby causing the swing brake 9 to move closer to the fixed friction device 8, locking the cable on the traction sheave 2, preventing the cable from sliding from the inside of the traction sheave 2 due to a fault, thereby improving the protection effect on the cable.

[0056] Furthermore, one end of the seat 71 is provided with a mounting groove 75 corresponding to the hydraulic cylinder 93, and the bottom of the hydraulic cylinder 93 is located inside the mounting groove 75. Moreover, the end of the hydraulic cylinder 93 is movably connected to the seat 71 through a pin, so that when the output rod of the hydraulic cylinder 93 extends or retracts, it can drive the flipping locking block 91 to flip above the seat 71.

[0057] Furthermore, the seat 71 is located on the lower side of the traction wheel 2, and the cable wound on the traction wheel 2 passes through the cable groove 72 downwards. The cable is guided by the arc-shaped guide groove 731 provided on the guide roller 73, and the anti-slip fixing block 81 and the flip locking block 91 are located on both sides of the cable respectively.

[0058] Furthermore, the electromagnetic gate opener 5 includes a housing 51 fixed above the platform mounting base 11. Push rods 52 are movably connected to both sides of the housing 51, and the other end of each push rod 52 is connected to a clamp 41. An electromagnet is also provided inside the housing 51. When the electromagnet is energized, it generates an attractive force, causing the push rods 52 on both sides to move outwards, pushing the clamp 41 to open, allowing the permanent magnet synchronous motor 1 to drive the traction wheel 2 and the brake disc 3 to rotate.

[0059] The working principle of this utility model is as follows: During use, the cable is first wound around the outside of the traction sheave, and each cable passes through the inner side of the cable groove 72. During normal operation, the flip-lock block 91 and the anti-slip fixing block 81 are in the open / closed state, and the cable passes normally between them. In case of a malfunction, the electromagnetic starter / stopper 5 loses power. At this time, the jaws 41 on both sides will clamp the brake disc 3 under the action of the locking spring 45, thereby stopping the traction sheave 2 from rotating. Simultaneously, the jaws 41 drive the connecting rod 64 to move through the integrally formed extended connecting post 42 on the side, thereby pushing the piston rods 63 on both sides of the oil reservoir 61 to retract inward, compressing the space inside the oil reservoir 61. Hydraulic oil inside the reservoir 61 enters the inner side of the hydraulic cylinder 93 through the oil pipe 10, thereby pushing the output rod of the hydraulic cylinder 93 to move outward. Then, through the rotational engagement between the connecting bushing 92 at the end of the output rod of the hydraulic cylinder 93 and the tilting locking block 91, the tilting locking block 91 moves closer to the anti-slip fixing block 81. Finally, through the mutual engagement of the protrusion 94 and the brake groove 82, the contact area between the tilting locking block 91 and the anti-slip fixing block 81 is increased, thereby locking the cable while the brake disc 3 brakes, preventing the cable from slipping from the outside of the traction sheave 2 due to strong impact force, and further improving the safety of the traction machine during use. The structure is simple, the operation is very convenient, and the manual labor intensity is effectively reduced.
