Description

Technical Field

[0001] This utility model belongs to the technical field of elevator braking devices, and in particular relates to a spring controller for an elevator braking device. Background Technology

[0002] As elevator usage frequency and operating speed continue to increase, the requirements for the reliability and safety of braking devices are becoming increasingly stringent. Traditional elevator braking devices with spring control suffer from problems such as unstable braking force and slow response speed, making it difficult to accurately meet the needs of complex working conditions. In addition, springs are prone to fatigue and aging after long-term use, leading to a decrease in braking force and posing safety hazards. Therefore, developing a spring controller that can achieve precise adjustment of spring force, real-time monitoring of spring status, and high reliability is of great significance for improving elevator braking performance and ensuring elevator safety.

[0003] However, the existing elevator braking device's spring controller has a long braking time during use, requiring the braking spring to be gradually compressed. This makes it difficult for the braking spring to generate sufficient elastic force in a short time, thus affecting the braking response speed. Utility Model Content

[0004] The purpose of this utility model is to provide a spring controller for an elevator braking device. By setting a locking part, it solves the problem that the existing spring controllers for elevator braking devices have a long braking time during use, requiring the brake spring to be gradually compressed, which makes it difficult for the brake spring to generate sufficient elastic force in a short time, thus affecting the braking response speed.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a spring controller for an elevator braking device, comprising an outer casing, and further comprising: a braking part installed inside the outer casing for transmitting braking force to the elevator; two locking parts, both of which are located inside the braking part; and two compression parts, both of which are located inside the braking part; wherein the two locking parts are used to generate braking force, and the two compression parts are used to assist the operation of the two locking parts, enabling the two locking parts to generate greater braking force.

[0007] Furthermore, the braking unit includes a circular groove formed inside the outer casing, a rotating shaft rotatably connected to the inner wall of the outer casing, a brake wheel fixedly connected to the outer wall of the rotating shaft, and the rotating shaft passing through the brake wheel; wherein, two grooves are formed on the front side of the outer casing, both grooves are connected to the circular groove, the brake wheel is located in the circular groove, and the rotating shaft passes through the outer casing, the rotating shaft is connected to the elevator, and the brake wheel brakes the elevator through the rotating shaft.

[0008] Furthermore, the locking part includes a spring assembly disposed in a circular groove; and a power storage assembly located inside the outer casing, with its rear side extending into the circular groove; wherein the spring assembly is used to generate braking force to brake the brake wheel, while the power storage assembly is used to assist the operation of the spring assembly and ensure the normal operation of the brake wheel when braking is not required.

[0009] Furthermore, the extrusion section includes a power assembly disposed within the outer casing; and a sliding assembly located on the power assembly, with its top extending into the spring assembly; wherein the power assembly is used to generate the power required to operate the sliding assembly, and the sliding assembly is used to drive the spring assembly to operate further.

[0010] Furthermore, the spring assembly includes a brake shoe hinged in a circular groove. Two hinge blocks are provided at the bottom of the brake shoe. A brake spring is fixedly connected to the inner wall of the upper hinge block, and the bottom of the brake spring is fixedly connected to the lower hinge block. The top of the upper hinge block is hinged to the brake shoe. When the locking part brakes the brake wheel, the brake spring is in a semi-compressed state. After the pressing part has finished operating and when the locking part is not braking, the brake spring is in a fully compressed state.

[0011] Furthermore, the power storage assembly includes a limiting groove on the front side of the brake shoe, a hydraulic cylinder is fixedly connected to the top inner wall of the outer casing, a slider is slidably connected to the inner wall of the outer casing, the output shaft of the hydraulic cylinder is fixedly connected to the slider, and a limiting member is provided inside the slider; wherein, the hydraulic cylinder and the slider are both located in the groove on the outer casing, and a groove is opened on the rear side of the slider, and the limiting member is located in the groove of the slider, and the rear side of the limiting member extends into the limiting groove. When the hydraulic cylinder drives the slider to move, the brake shoe will rotate through the limiting member and the limiting groove.

[0012] Furthermore, the power assembly includes a motor fixedly connected to the inner wall of the outer casing, and a threaded rod is rotatably connected to the inner wall of the outer casing; wherein, when the motor rotates, it drives the threaded rod to rotate, thereby providing power to the sliding assembly.

[0013] Furthermore, the sliding assembly includes a slide groove formed inside the outer casing, the top of the slide groove being connected to a circular groove, a slider three being slidably connected to the inner wall of the slide groove, a threaded hole being formed on the side of the slider three near the threaded rod, the outer wall of the threaded rod being threadedly connected to the threaded hole, and the top of the slider three being hinged to a hinge block located below; wherein, when the threaded rod rotates, it will drive the slider three to slide, thereby applying pressure to the brake spring through the hinge block.

[0014] Furthermore, the limiting component includes a hydraulic cylinder two fixedly connected to the inner wall of the slider one, the inner wall of the slider one being slidably connected to the slider two, and the output shaft of the hydraulic cylinder two being fixedly connected to the slider two; wherein, the slider two slides out or slides into the slider one under the action of the hydraulic cylinder two, and both the hydraulic cylinder two and the slider two are located in the groove of the slider one, and the slider two is a cylindrical block used to drive the brake shoe to rotate through the limiting groove.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting a locking mechanism, during use, hydraulic cylinder one can be activated to make its output shaft slide upward, which in turn drives hydraulic cylinder two to slide upward. When the slider two in hydraulic cylinder two moves to the position corresponding to the limit groove, hydraulic cylinder two can be activated to make it drive slider two to slide into the limit groove. Then, hydraulic cylinder one can be activated to make its output shaft drive slider one to slide downward, thereby driving the brake shoe away from the brake wheel through slider two and the limit groove. During this process, pressure is applied to the brake spring through the hinge block, causing it to be fully compressed and accumulate a large amount of elastic force. When braking is required, hydraulic cylinder two can be activated to make it drive slider two to slide out of the limit groove. At this time, the brake shoe is no longer restricted, and the brake shoe grips the brake wheel under the action of the hinge block's elastic force, thus braking it. It can quickly lock the brake wheel when braking is required without gradually compressing the brake spring, allowing the brake spring to quickly generate a large amount of elastic force, thereby shortening the braking response time.

[0017] 2. By setting up a compression section, when the brake shoes grip the brake wheel, the motor can be started to rotate its output shaft, thereby driving the threaded rod and pushing the slider three to slide in the groove. During this process, the hinge block on the slider three will apply pressure to the brake spring, causing it to continue to compress until it is fully compressed. This ensures that the braking force reaches its maximum when gripping the brake wheel. After the brake wheel is locked, the brake spring can be further squeezed to return to the fully compressed state, thereby increasing the magnitude of the braking force and making the brake wheel lock up more quickly.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-6As shown, this utility model is a spring controller for an elevator braking device, including an outer casing 101, and further including: a braking part 1, which is installed inside the outer casing 101 and is used to transmit braking force to the elevator; two locking parts 2, both of which are disposed inside the braking part 1; and two pressing parts 3, both of which are located inside the braking part 1; wherein, the two locking parts 2 are used to generate braking force, and the two pressing parts 3 are used to assist the operation of the two locking parts 2, so that the two locking parts 2 generate braking force. To generate greater braking force, the braking unit 1 includes a circular groove 102 formed inside the outer casing 101. A rotating shaft 103 is rotatably connected to the inner wall of the outer casing 101, and a brake wheel 104 is fixedly connected to the outer wall of the rotating shaft 103. The rotating shaft 103 passes through the brake wheel 104. The front side of the outer casing 101 has two grooves, both of which are connected to the circular groove 102. The brake wheel 104 is located inside the circular groove 102, and the rotating shaft 103 passes through the outer casing 101. The rotating shaft 103 is connected to the elevator, and the brake wheel 104 brakes the elevator through the rotating shaft 103.

[0030] The locking mechanism 2 includes a spring assembly 21 disposed within a circular groove 102; and a power storage assembly 22 located within an outer casing 101, with its rear side extending into the circular groove 102. The spring assembly 21 generates braking force to brake the brake wheel 104, while the power storage assembly 22 assists the spring assembly 21 in operation and ensures the normal operation of the brake wheel 104 when braking is not required. The spring assembly 21 includes brake shoes 211 hinged within the circular groove 102, with two hinge blocks 212 at the bottom of the brake shoes 211, and the upper hinge block 212 fixed to its inner wall. A brake spring 213 is connected, with its bottom fixedly connected to a lower hinge block 212. The top of the upper hinge block 212 is hinged to the brake shoe 211. When the locking part 2 brakes the brake wheel 104, the brake spring 213 is in a semi-compressed state. After the compression part 3 has finished operating and when the locking part 2 is not braking, the brake spring 213 is in a fully compressed state. The power storage assembly 22 includes a limiting groove 221 opened on the front side of the brake shoe 211. A hydraulic cylinder 222 is fixedly connected to the top inner wall of the outer casing 101, and a slider 223 is slidably connected to the inner wall of the outer casing 101. The output shaft of hydraulic cylinder 222 is fixedly connected to slider 223, and a limiting member is provided inside slider 223. Both hydraulic cylinder 222 and slider 223 are located in grooves on the outer casing 101, and a groove is opened on the rear side of slider 223. The limiting member is located in the groove of slider 223, and its rear side extends into the limiting groove 221. When slider 223 is moved by hydraulic cylinder 222, the brake shoe 211 rotates through the limiting member and the limiting groove 221. The limiting member includes hydraulic cylinder 224 fixedly connected to the inner wall of slider 223, and a sliding member is slidably connected to the inner wall of slider 223. Block 225, the output shaft of hydraulic cylinder 224 is fixedly connected to slider 225; wherein, slider 225 slides out or slides in from slider 1 223 under the action of hydraulic cylinder 224, and both hydraulic cylinder 224 and slider 225 are located in the groove of slider 1 223. Slider 225 is a cylindrical block, used to drive brake shoe 211 to rotate through limit groove 221. By setting locking part 2, the brake wheel 104 can be quickly locked when braking is needed, without gradually compressing brake spring 213, so that brake spring 213 can quickly generate a large amount of elastic force, thereby shortening the time required for braking response.

[0031] The extrusion section 3 includes a power assembly 31 disposed within the outer casing 101; and a sliding assembly 32 located on the power assembly 31, with its top extending into the spring assembly 21. The power assembly 31 generates the power required to operate the sliding assembly 32, while the sliding assembly 32 pushes the spring assembly 21 further. The power assembly 31 includes a motor 311 fixedly connected to the inner wall of the outer casing 101, and a threaded rod 312 rotatably connected to the inner wall of the outer casing 101. When the motor 311 rotates, it drives the threaded rod 312 to rotate, providing power to the sliding assembly 32. The sliding assembly 32 includes a groove formed within the outer casing 101. 321, the top of the slide groove 321 is connected to the circular groove 102, and the inner wall of the slide groove 321 is slidably connected to the slider 322. The slider 322 has a threaded hole on the side near the threaded rod 312. The outer wall of the threaded rod 312 is threadedly connected to the threaded hole. The top of the slider 322 is hinged to the hinge block 212 located below. When the threaded rod 312 rotates, it will drive the slider 322 to slide, thereby applying pressure to the brake spring 213 through the hinge block 212. By setting the compression part 3, the brake spring 213 can be further compressed after the brake wheel 104 is locked, so that it returns to the fully compressed state, thereby increasing the braking force and making the brake wheel 104 lock up faster.

[0032] A specific application of this embodiment is as follows: In use, hydraulic cylinder 222 can be activated to make its output shaft slide upward, which in turn drives hydraulic cylinder 224 to slide upward. When the slider 225 in hydraulic cylinder 224 moves to the position corresponding to the limiting groove 221, hydraulic cylinder 224 can be activated to make it drive slider 225 to slide into the limiting groove 221. Then, hydraulic cylinder 222 can be activated to make its output shaft drive slider 223 to slide downward. This causes the brake shoe 211 to move away from the brake wheel 104 through slider 225 and the limiting groove 221. During this process, pressure is applied to the brake spring 213 through the hinge block 212, causing it to be fully compressed and accumulate a large amount of elastic force. When braking is required, hydraulic cylinder 224 can be activated, causing slider 225 to slide out of limit groove 221. At this time, brake shoe 211 is no longer restricted, and under the action of the spring force of hinge block 212, brake shoe 211 clamps brake wheel 104 to brake it. When brake shoe 211 clamps brake wheel 104, motor 311 can be activated to rotate its output shaft, thereby driving threaded rod 312 to push slider 322 to slide in slide groove 321. During this process, the hinge block 212 on slider 322 will apply pressure to brake spring 213, causing it to continue to compress and finally fully compress, thereby ensuring that the braking force reaches the maximum when clamping brake wheel 104.
