Description

Technical Field

[0001] This utility model relates to the field of elevator safety technology, and more specifically, to an elevator emergency braking and stabilizing locking device. Background Technology

[0002] In the field of elevator operation safety, emergency braking and stabilization locking devices are of paramount importance. Currently, there are various elevator emergency braking devices on the market that have played a positive role in ensuring elevator safety.

[0003] Existing publication number CN207483108U discloses an emergency braking device for elevators, including a lifting channel. Baffles are fixed to both sides of the inner wall edge of the lifting channel, and guide rails are provided on the baffles. A drive motor is installed at the top of the lifting channel, and a lifting wheel is installed on one side of the drive motor. By incorporating a reducer, brake shoe, emergency braking component, and brake button, it solves the problems of poor braking effect, excessive heat generation during braking, and poor buffering effect in current elevator emergency braking devices. The inventors discovered the following problems in the prior art during the development of this utility model:

[0004] In some existing devices, due to design limitations of the braking mechanism, there is a certain delay between receiving the braking signal and actually completing the braking action after an emergency is triggered. This makes it impossible to achieve rapid braking instantly, causing the elevator to continue to run a certain distance before braking, which increases the risk of accidents. At the same time, during the braking process, the elevator is easily affected by factors such as elevator operation vibration and external impact, which may cause the locking to loosen or even fail, making it difficult to ensure that the elevator remains stably stationary after braking.

[0005] Therefore, an elevator emergency braking and stabilizing locking device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an elevator emergency braking stabilization and locking device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an elevator emergency braking stabilizing locking device, comprising a positioning frame, a threaded mounting position designed on the upper side of the positioning frame, through which a positioning screw is securely threadedly mounted; through holes symmetrically opened on both sides of the positioning frame, a locking rod inserted into the through holes, the locking rod being able to slide to a certain extent within the through holes; a compression spring sleeved on the outer side of the locking rod; a positioning plate provided at one end of the locking rod; a telescopic rod fixedly connected to the end of the positioning plate away from the locking rod; a limiting sleeve sleeved on the outer side of the telescopic rod, the limiting sleeve having a limiting opening at its top; a fixing rod fixedly mounted on the top of the telescopic rod, the fixing rod being located in the area of ​​the limiting opening; a motor verifier threadedly mounted on the top of the fixing rod; a positioning seat detachably mounted on the top of the motor verifier; and a wire detachably mounted inside the motor verifier.

[0008] Preferably, a buffer pad is installed on the inner wall of the positioning frame, and the buffer pad is located on one side of the through hole. When the locking rod is inserted into the through hole, a buffer pad is also sleeved on the outer side of the locking rod.

[0009] Preferably, the telescopic rod passes through a pre-drilled hole in the positioning frame. The telescopic rod does not remain inside the positioning frame. After entering through a hole on one side of the positioning frame, it extends out through a corresponding hole on the other side to the outside of the positioning frame.

[0010] Preferably, a protective pad is detachably placed on one side of the positioning frame, and a limiting hole is opened laterally on the upper side of the protective pad. The limiting hole penetrates the protective pad itself and extends into the interior of the positioning frame.

[0011] Preferably, a guide rod is fixedly installed on the upper side of the telescopic rod by welding. The size and shape of the guide rod match the inner diameter of the limiting hole. When the telescopic rod moves in extension or retraction, the guide rod moves synchronously within the limiting hole.

[0012] Preferably, a positioning plate is detachably installed inside the positioning frame. The shape and size of the positioning plate are adapted to the installation space inside the positioning frame. During installation, both sides of the positioning plate are in close contact with the inner wall of the positioning frame and the inside of the motor verifier, respectively.

[0013] Preferably, the positioning plate is designed with mounting holes for fixing bolts on both sides. During installation, the fixing bolts are inserted into the holes on both sides of the positioning plate. The fixing bolts pass through the corresponding holes pre-drilled on the positioning frame and extend further to the outside of the positioning frame. The threads of the fixing bolts extending to the outside of the positioning frame are fitted with matching nuts.

[0014] Preferably, an anti-detachment plate is fixedly installed on one side of the telescopic rod by welding, and the size and shape of the anti-detachment plate are adapted to the telescopic rod.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with the prior art, this elevator emergency braking and stabilizing locking device achieves rapid braking by using a compression spring sleeved on the outside of the locking rod in terms of response speed. When braking is triggered, the compression spring releases its elastic force instantly, pushing the locking rod to slide quickly in the through hole and extend, thereby greatly shortening the braking response time.

[0017] 2. Compared with existing technologies, this elevator emergency braking stabilizing locking device extends to the outside through a telescopic rod that passes through the positioning frame. The guide rod on its upper side moves synchronously within the limiting hole of the protective pad, providing guidance for the telescopic rod and preventing it from deviating. At the same time, the positioning plate, which can be detachably installed inside the positioning frame, is fastened on both sides by fixing bolts and nuts, making close contact with the inside of the motor verifier, further enhancing the overall structural stability. In addition, the buffer pads set on the inner wall of the positioning frame and the outer side of the locking rod can buffer the impact force during braking and reduce component wear. Through multiple structural designs, this device achieves rapid response and stable locking, improving the safety and reliability of elevator emergency braking. Attached Figure Description

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.

[0024] Example 1

[0025] As attached Figures 1 to 4 An elevator emergency braking and stabilizing locking device is shown, comprising a positioning frame 1. The upper side of the positioning frame 1 is designed with a threaded mounting position, through which a positioning screw 2 is securely threadedly mounted. Through holes 3 are symmetrically opened on both sides of the positioning frame 1. A locking rod 4 is inserted into the through hole 3 and can slide to a certain extent within the through hole 3. A compression spring 5 is sleeved on the outer side of the locking rod 4. A positioning plate 7 is provided at one end of the locking rod 4. A telescopic rod 8 is fixedly connected to the end of the positioning plate 7 away from the locking rod 4. A limiting sleeve 9 is sleeved on the outer side of the telescopic rod 8. A limiting opening 10 is opened at the top of the limiting sleeve 9. A fixing rod 11 is fixedly installed at the top of the telescopic rod 8. The fixing rod 11 is located in the area of ​​the limiting opening 10. A motor verifier 12 is threadedly installed at the top of the fixing rod 11. A positioning seat 13 is detachably installed at the top of the motor verifier 12. A wire 14 is detachably installed inside the motor verifier 12.

[0026] The positioning frame 1 has a threaded mounting position on its upper side and a positioning screw 2 is installed. The positioning can be adjusted according to actual needs, enhancing the applicability of the device. Symmetrical through holes 3 are opened on both sides, into which a sliding locking rod 4 is inserted and a compression spring 5 is fitted. During braking, the spring force can make the locking rod 4 respond quickly to achieve stable locking and improve braking reliability. The positioning plate 7 is connected to the telescopic rod 8. The telescopic rod 8 is fitted into the limiting sleeve 9 and the top fixing rod 11 is located in the limiting port 10 area, which can limit the telescopic range and ensure stable movement. The top of the fixing rod 11 is threaded with a motor verifier 12, which can verify the braking status in time to ensure safety. The top of the motor verifier 12 can be detachably installed with a positioning seat 13 and the inside can be detachably installed with a wire 14, which facilitates later maintenance and replacement of parts, reduces maintenance costs, and extends the service life of the device.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0029] In a preferred embodiment, a buffer pad 6 is installed on the inner wall of the positioning frame 1. The buffer pad 6 is located on one side of the through hole 3. When the locking rod 4 is inserted into the through hole 3, the buffer pad 6 can effectively buffer the impact, preventing the locking rod 4 from directly colliding with the inner wall of the positioning frame 1, and reducing wear and noise caused by the collision. At the same time, a buffer pad 6 is also fitted on the outer side of the locking rod 4. This buffer pad 6 can further absorb the impact force generated by the locking rod 4 during the movement, enhance the stability and durability of the device, and ensure that the locking rod 4 can maintain a good working condition during long-term use.

[0030] In a preferred embodiment, the telescopic rod 8 passes through a pre-drilled hole in the positioning frame 1. The telescopic rod 8 does not remain inside the positioning frame 1. After entering through a hole on one side of the positioning frame 1, it extends out through a corresponding hole on the other side to the outside of the positioning frame 1. This ensures that the telescopic rod 8 has sufficient support and guidance inside the positioning frame 1, and also allows it to have enough space to telescopically extend and retract outside the positioning frame 1 to meet the usage requirements under different working conditions.

[0031] In a preferred embodiment, a protective pad 15 is detachably placed on one side of the positioning frame 1, which facilitates the replacement or cleaning of the protective pad 15 according to the actual use. A limiting hole 16 is opened horizontally on the upper side of the protective pad 15. The limiting hole 16 penetrates the protective pad 15 itself and extends into the interior of the positioning frame 1. The limiting hole 16 can cooperate with other components to ensure that the position of each component is stable during the operation of the device and avoid shaking or displacement.

[0032] In a preferred embodiment, a guide rod 17 is fixedly installed on the upper side of the telescopic rod 8 by welding, ensuring a high-strength connection between the guide rod 17 and the telescopic rod 8, which can withstand various forces during the operation of the device. The size and shape of the guide rod 17 match the inner diameter of the limiting hole 16, so that the guide rod 17 can pass smoothly through the limiting hole 16. When the telescopic rod 8 moves in extension and retraction, the guide rod 17 moves synchronously within the limiting hole 16. The limiting hole 16 provides a stable movement track for the guide rod 17, ensuring that the extension and retraction direction of the telescopic rod 8 is accurate and improving the stability of the entire device operation.

[0033] In a preferred embodiment, a positioning piece 19 is detachably installed inside the positioning frame 1. The shape and size of the positioning piece 19 are adapted to the installation space inside the positioning frame 1. During installation, both sides of the positioning piece 19 are in close contact with the inner wall of the positioning frame 1 and the interior of the motor verifier 12, respectively. This close contact provides stable support for the positioning piece 19 with the help of the positioning frame 1, preventing it from loosening or shifting during use. On the other hand, the positioning piece 19 also plays an auxiliary positioning role for the motor verifier 12, ensuring the installation position of the motor verifier 12 on the positioning frame 1 and improving the overall stability of the device operation.

[0034] In a preferred embodiment, fixing bolts 20 are inserted into both sides of the positioning piece 19. The fixing bolts 20 penetrate the positioning frame 1 and extend to the outside of the positioning frame 1. Nuts 21 are threaded onto the outer side of the fixing bolts 20. The two sides of the positioning piece 19 are designed with mounting holes for the fixing bolts 20. During installation, the fixing bolts 20 are inserted into the holes on both sides of the positioning piece 19. The fixing bolts 20 penetrate the corresponding holes pre-drilled on the positioning frame 1 and further extend to the outside of the positioning frame 1. The threads of the fixing bolts 20 extending to the outside of the positioning frame 1 are threaded with matching nuts 21. By tightening the nuts 21, they are made to fit tightly against the outer surface of the positioning frame 1. Under the action of the nuts 21 and the heads of the fixing bolts 20, the positioning piece 19 is firmly fixed inside the positioning frame 1, ensuring that the positioning piece 19 is in a stable position and will not shift during use.

[0035] In a preferred embodiment, an anti-detachment plate 18 is fixedly installed on one side of the telescopic rod 8 by welding. Before welding, the contact surfaces of the telescopic rod 8 and the anti-detachment plate 18 are treated to ensure welding quality. During welding, appropriate welding parameters are used to ensure a high-strength connection between the anti-detachment plate 18 and the telescopic rod 8. The size and shape of the anti-detachment plate 18 are adapted to the telescopic rod 8, effectively preventing related components from falling off during the telescopic rod 8's extension and retraction, providing reliable protection and avoiding safety hazards caused by component detachment.

[0036] In this embodiment, the locking lever 4, the compression spring 5, and the motor verifier 12 are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, and we will not go into detail about them here.

[0037] The working process of this utility model is as follows: First, the positioning frame 1 is securely installed in a suitable position in the elevator car using the positioning screw 2 through the threaded mounting position on its upper side. At this time, the buffer pad 6 on the inner wall of the positioning frame 1 and the outer side of the locking rod 4 can buffer the impact force during subsequent braking and reduce the wear of the parts; then, the locking rod 4 is inserted into the through holes 3 on both sides of the positioning frame 1, so that it can slide in the through holes 3, and the compression spring 5 is fitted on it; the positioning plate 7 at one end of the locking rod 4 is fixedly connected to the telescopic rod 8, the telescopic rod 8 extends to the outside through the pre-opened hole in the positioning frame 1, and the outer side is fitted with the upper limit sleeve 9, and the fixing rod 11 at the top of the telescopic rod 8 is located in the limiting port 10 area at the top of the limiting sleeve 9; then, a protective pad 15 is detachably placed on one side of the positioning frame 1, the upper side of which has a horizontally opened limiting hole 16 that extends through and into the interior of the positioning frame 1, which matches the size and shape of the guide rod 17 welded to the upper side of the telescopic rod 8. When the telescopic rod 8 extends or retracts, the guide rod 17 moves synchronously within the limiting hole 16 to achieve precise guidance. Next, the motor verifier 12 is threaded onto the top of the fixed rod 11, and a positioning seat 13 is detachably installed on its top. A wire 14 is detachably installed inside for connecting to the elevator control system. At the same time, a matching positioning piece 19 is detachably installed inside the positioning frame 1. Fixing bolts 20 pass through the corresponding holes of the positioning frame 1 on both sides, and nuts 21 are used to lock it on the outside of the positioning frame 1, so that the two sides of the positioning piece 19 are in close contact with the inner wall of the positioning frame 1 and the inside of the motor verifier 12, respectively. Next, a matching anti-detachment plate 18 is welded to one side of the telescopic rod 8 to prevent the telescopic rod 8 from falling off. Finally, when the elevator experiences an emergency and triggers braking, the compression spring 5 pushes the locking rod 4 to slide out quickly within the through hole 3 for braking. During braking, the telescopic rod 8, the limiting sleeve 9, the fixed rod 11, and other structures ensure stable locking. The guide rod 17 moves within the limiting hole 16 to ensure that the telescopic rod 8 does not deviate. After braking is completed, the motor verifier 12 feeds back braking information to the elevator control system.

[0038] The above describes the working principle of this elevator emergency braking and stabilizing locking device.
