Description

Technical Field

[0001] This utility model relates to the field of elevator brake release control devices, and in particular to an adaptive balancing elevator brake release control device. Background Technology

[0002] An elevator is a power-driven electromechanical device that uses a car that runs along rigid guide rails or steps that run along a fixed route to lift or transport people or goods in parallel. It includes passenger elevators, escalators, moving walkways, etc., and serves a building with a specified number of floors.

[0003] The elevator brake release control device is used to control the release operation of the elevator brake, playing an important role in elevator maintenance, repair, and emergencies. It typically consists of a manual brake release wrench and an electric brake release mechanism. The manual brake release wrench is generally a lever-type or wrench-type tool connected to the brake's control mechanism. The electric brake release mechanism includes components such as a motor, reducer, and clutch, and is operated through an electrical control system.

[0004] When manually releasing the brake, the operator uses a brake release wrench to overcome the pressure of the brake spring, causing the brake arm to open and thus releasing the brake. In practice, due to the limitations of the brake release cable installation, most manual brake release handles usually require considerable force to operate, and the wrench is often retracted into a confined space to reduce space requirements. This leads to operational difficulties and delays in releasing the brake.

[0005] Therefore, it is necessary to provide an adaptive balancing elevator brake release control device to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides an adaptive balancing elevator brake release control device, which solves the problem that in some existing elevator brake release control devices, the handles are difficult to turn and space is limited due to the effect of the brake release wire installation, which leads to operational difficulties and affects the brake release process.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 An adaptive balancing elevator brake release control device includes: a mounting base 1, a brake release component 2 disposed on the front of the mounting base 1, and an actuation component 3 disposed on the front of the mounting base 1 and to the right of the brake release component 2.

[0024] The brake release assembly 2 includes a first fixing frame 21 disposed on the left side of the front of the mounting base 1. A guide wheel 22 is rotatably disposed on the inner side of the first fixing frame 21. A brake release wire 23 is disposed on the front of the mounting base 1. The front end of the brake release wire 23 is fixed to the peripheral side of the guide wheel 22.

[0025] By rotating the guide wheel 22, the guide wheel 22 rotates and tightens the brake release wire 23. The brake release wire 23 is linked to the pulley, which drives the external brake shoe to disengage from the brake wheel, thereby completing the brake release operation.

[0026] The lever assembly 3 includes a second fixing frame 31 located on the right side of the front of the mounting base 1. A connecting rod 32 is rotatably provided on the inner side of the second fixing frame 31. The left end of the connecting rod 32 passes through the inner side of the second fixing frame 31 and extends to its left side. A small gear 33 is provided on the peripheral side of the connecting rod 32 on the side of the second fixing frame 31 opposite to the first fixing frame 21. The right end of the guide wheel 22 passes through the inner side of the first fixing frame 21 and extends to its right side. A large gear 34 is provided on the peripheral side of the guide wheel 22 on the side of the second fixing frame 31 opposite to the first fixing frame 21. The front side of the small gear 33 meshes with the rear side of the large gear 34.

[0027] By setting two gears, with the small gear 33 driving the large gear 34, effort can be saved and the difficulty of rotation can be reduced.

[0028] A chuck 35 is fixedly installed on the periphery of the connecting rod 32. A lever 36 is rotatably installed on the inner side of the second fixing frame 31. A spring block 37 is slidably installed on the inner side of the lever 36. The bottom of the spring block 37 engages with the top of the chuck 35.

[0029] When rotating, the user holds the top of the lever 36 and presses it forward. When pressing to a certain angle, it becomes difficult to maintain the force angle when pressing further. The user can then lift the lever 36 upward to rotate it around the second fixed frame 31, thereby restoring the front end of the lever 36 to a suitable angle for applying force. During this process, when the lever 36 is lifted upward, the bottom of the spring clip 37 is tilted. Under the action of the chuck 35, the spring clip 37 retracts into the inside of the lever 36 and disengages from the chuck 35, allowing the lever 36 to rotate upward.

[0030] The top of the chuck 35 is provided with an unlocking rope 38. The top of the unlocking rope 38 and the inside of the lever 36 are provided with a guide block 39 that can slide up and down. The back of the lever 36 is provided with a push block 4 that can slide back and forth. When the push block 4 moves backward, it will push the guide block 39 to rise.

[0031] When the circuit needs to be closed, the push block 4 is pressed inward, causing the push block 4 to push the guide block 39 to move upward, thereby pulling the unlocking rope 38 upward, which in turn causes the spring block 37 to disengage from the chuck 35. At this time, the connecting rod 32 can rotate in the opposite direction.

[0032] The left end of the guide wheel 22 is rotatably connected to the left side of the second fixed frame 31. A ratchet 5 is provided on the circumferential side of the guide wheel 22 and on the right side of the large gear 34. A rotatable pawl 6 is provided on the left side of the second fixed frame 31, and the front end of the pawl 6 engages with the bottom of the ratchet 5.

[0033] By incorporating a ratchet 5, a pawl 6, and a spring, the guide wheel 22 is prevented from reversing after rotation, thus eliminating the need for manual pressure on the lever 36 and reducing labor intensity.

[0034] A spring is provided on the left side of the second fixing bracket 31, and the bottom of the spring is fixedly connected to the top of the pawl 6.

[0035] An unlocking pull ring 7 is fixedly installed at the bottom of the pawl 6.

[0036] When it is necessary to close the circuit, the unlocking ring 7 can be pulled down to make the pawl 6 rotate and disengage from the ratchet 5, so that the guide wheel 22 can be automatically reset under the tension of the release wire 23.

[0037] The working principle of the adaptive balancing elevator brake release control device provided by this utility model is as follows:

[0038] Step 1: When it is necessary to release the brake, press the push block 4 forward to rotate the lever 36, making it easier for the person to exert force on it. Then press down on the handle of the lever 36 to drive the connecting rod 32 to rotate, which in turn drives the small gear 33 to rotate. When the small gear 33 rotates, it will drive the large gear 34 and the guide wheel 22 to rotate, thereby pulling the release wire 23 and releasing the elevator's brake device.

[0039] Step 2: The small gear 33 drives the large gear 34, which can save the user's strength, but requires a lot of rotation. When the handle of the lever 36 is rotated to a position where it is inconvenient to exert force, the lever 36 can be lifted directly upward. During this process, because the bottom of the spring block 37 is inclined, under the action of the chuck 35, the spring block 37 retracts into the inside of the lever 36 and disengages from the chuck 35, so that the lever 36 can be rotated upward. The lever 36 after being lifted can better adapt to the angle of force exerted by the user.

[0040] Step 3: During the rotation of the guide wheel 22, the ratchet 5, pawl 6 and spring are provided to prevent the guide wheel 22 from reversing after rotation, thereby eliminating the need for personnel to press on the lever 36 and reducing labor intensity.

[0041] Step 4: When it is necessary to close the circuit, pull down the unlocking ring 7 to make the pawl 6 rotate and disengage from the ratchet 5. At the same time, by pressing the push block 4 inward, the push block 4 pushes the guide block 39 to move upward, thereby pulling the unlocking rope 38 upward, which in turn drives the spring block 37 to disengage from the chuck 35. At this time, the connecting rod 32 can rotate in the opposite direction, so that the guide wheel 22 can be reset by itself under the tension of the release wire 23.

[0042] Compared with related technologies, the adaptive balancing elevator brake release control device provided by this utility model has the following beneficial effects:

[0043] The system features a chuck 35, a lever 36, and a spring block 37, allowing for self-adjustment of the angle at which the operator applies force to the lever 36. This makes it more suitable for use in confined workspaces. The small gear 33 drives the large gear 34 and guide wheel 22, reducing the workload for operators and providing a good solution for handles that are difficult to turn. Finally, the push block 4 and unlocking pull ring 7 enable quick closing of the circuit. The system is simple in structure, easy to operate, and highly practical.
