Description

Technical Field

[0001] This application relates to the field of elevator parts technology, and in particular to a safety clamp that occupies little space. Background Technology

[0002] An elevator safety clamp is a mechanical safety protection device installed at the bottom of the elevator car frame or counterweight frame. It is one of the three major safety components of an elevator. Its core structure includes a clamp body, a wedge, an elastic element, and a linkage triggering mechanism. Its working principle is based on mechanical linkage and friction braking, and does not rely on electric or hydraulic drives. When an abnormal operating condition triggers the protection mechanism, the linkage mechanism drives the wedge to move towards the elevator guide rail. The preload of the elastic element ensures the wedge is tightly fitted against the guide rail. Utilizing the strong mechanical friction generated between them, the car or counterweight is forced to decelerate and stop. It is the last line of mechanical safety defense against overspeed and runaway elevator malfunctions. During elevator operation, the safety brake and speed governor form the core linkage protection system, covering various sudden failures and special operating conditions. These include: the car exceeding the safety threshold of 115% of its rated speed during downward travel; loss of control during upward travel near the top; breakage of one or more suspension cables; slippage of the traction sheave causing uncontrolled car runaway; failure of traction system components; and unexpected car movement due to improper operation during elevator maintenance. Its core function is to precisely trigger the safety brake linkage mechanism by the speed governor when the above conditions occur, causing the wedges to quickly clamp the guide rails. Through mechanical friction, the car or counterweight is forced to a smooth stop and locked onto the guide rails, completely preventing serious accidents such as car falls or overshooting. Simultaneously, it avoids damage to the equipment structure during braking, maximizing the safety of passengers and the stability of elevator operation.

[0003] Most existing safety clamps are installed at the bottom of the elevator car or on the car frame. The speed governor precisely triggers the safety clamp linkage mechanism, causing the wedges to quickly clamp the guide rail. Through mechanical friction, the car or counterweight is forced to stop smoothly and lock onto the guide rail. However, the spacing of the wedges in existing safety clamps is mostly fixed, and the spacing of the safety clamp wedges cannot be adjusted. This makes it difficult to adjust and adapt the safety clamp according to the width of the guide rail, which is not conducive to the rapid adaptation and installation of the safety clamp. Summary of the Invention

[0004] The purpose of this application is to address the problem that in the prior art, the spacing of the wedges in most existing safety clamps is fixed, and the spacing of the wedges cannot be adjusted, making it difficult to adjust and adapt the safety clamp according to the width of the guide rail, which is not conducive to the rapid adaptation and installation of the safety clamp. This application provides a safety clamp that occupies less space.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution: A space-saving safety clamp includes a mounting plate, a connecting frame mounted on the bottom of the mounting plate, a connecting plate mounted on the bottom of the connecting frame, symmetrical adjusting seats slidably mounted between the mounting plate and the connecting plate, symmetrical limiting plates fixedly connected to one side of each adjusting seat, a slide rail formed between the two limiting plates, a wedge block slidably mounted within the slide rail, a lifting arm rotatably connected to the bottom of each wedge block, an auxiliary reset component mounted between the connecting plate and the lifting arm, a guide wheel mounted on the inclined side of the adjusting seat, a blocking component mounted on one side of the interior of the mounting plate, and symmetrical cleaning components for cleaning the track mounted on the bottom of the connecting plate, with the wedge block and the cleaning component being drive-connected.

[0006] By adopting the above technical solution, when the safety clamp needs to be installed on guide rails of different widths, the two adjusting seats can be manually operated to make the internal components of the adjusting seats slide between the mounting plate and the connecting plate, thereby moving the two adjusting seats closer or further apart and adjusting the gap between them according to the width of the guide rail, thus making it easier for the safety clamp to adapt to guide rails of different widths.

[0007] When the lifting arm drives the wedges, the two wedges move along the tilt direction of the adjusting seat and towards the guide rail. By pressing against the guide rail, the car can be safely braked. During the movement of the wedges, they contact the guide wheel. The internal components of the guide wheel reduce the friction generated during the movement of the wedges, thereby improving the smoothness of the wedge movement, reducing the phenomenon of jamming during the movement of the wedges, and thus improving the braking synchronization and safety of the two wedges.

[0008] Furthermore, the mounting plate and the connecting plate are provided with sliding grooves on their corresponding sides, and the adjusting seat is slidably installed in the sliding grooves.

[0009] By adopting the above technical solution, the distance between the two adjusting seats can be adjusted by sliding the adjusting seat in the slide groove.

[0010] Furthermore, the adjusting seat includes a guide block that is slidably installed between the mounting plate and the connecting plate. Both the upper and lower ends of the guide block are fixedly connected to sliders. The sliders are slidably installed inside the slide groove. One side of the guide block is threadedly connected to a threaded slide rod, and one side of the threaded slide rod is threadedly connected to multiple sets of fixing nuts.

[0011] By adopting the above technical solution, the guide block is manually pushed, causing the guide block to slide in the groove, thereby adjusting the distance between the two guide blocks and thus adjusting the distance between the two wedges.

[0012] Furthermore, the auxiliary reset component includes connecting plates that are respectively fixedly connected to the bottom of the connecting plate and the lifting arm, and an elastic element is rotatably connected between the two connecting plates.

[0013] By adopting the above technical solution, the two connecting plates can be pulled back and reset under the elastic action of the elastic element, which can assist the lifting arm in quick reset.

[0014] Furthermore, the elastic element includes a sleeve rod rotatably connected to a connecting plate on one side, a tension spring fixedly connected inside the sleeve rod, an inner rod fixedly connected to one end of the tension spring, and the inner rod rotatably connected to the connecting plate on the other side.

[0015] By adopting the above technical solution, the inner rod is pulled back under the elastic action of the tension spring, causing the inner rod to retract and move in the direction of the sleeve rod, thereby applying a pull-back force to the lifting arm.

[0016] Furthermore, the guide wheel component includes a mounting bracket fixedly connected to the inclined side of the guide block, and a plurality of guide rollers are rotatably connected to the mounting bracket.

[0017] By adopting the above technical solution, the friction generated when the wedge moves can be reduced by the guide roller, thereby improving the smoothness of the wedge movement.

[0018] Furthermore, the cleaning component includes a linkage plate symmetrically rotatably connected to the bottom of the connecting plate, a brush plate fixedly connected to one side of the linkage plate, threaded limit rods threadedly connected to both the guide block and the linkage plate, and a pull plate rotatably connected between the two threaded limit rods.

[0019] By adopting the above technical solution, the brush plate can be used to clean the dust or debris adhering to the side of the guide rail.

[0020] Furthermore, a second symmetrical sliding cavity is provided on one side of the mounting plate, and a first sliding cavity is provided on one side inside the second sliding cavity.

[0021] By adopting the above technical solutions, slide cavity one and slide cavity two can provide space for the movement of internal components of the blocking component.

[0022] Furthermore, the blocking component includes a baffle that is slidably installed inside the second sliding cavity. A driving block is fixedly connected to one side of the baffle. The driving block is slidably installed inside the first sliding cavity, and driving components are installed on the two driving blocks.

[0023] By adopting the above technical solution, the two drive blocks can be driven by operating the drive components, thereby driving the baffle.

[0024] Furthermore, the driving component includes a bidirectional threaded rod rotatably connected inside the mounting plate, with both ends of the bidirectional threaded rod threadedly connected to the driving block, and a cross-grooved handle fixedly connected to one end of the bidirectional threaded rod.

[0025] By adopting the above technical solution, the bidirectional threaded rod can be rotated by driving the cross-groove handle with an external tool, thereby driving the drive block and the baffle.

[0026] In summary, this application includes at least one of the following beneficial effects; 1. In this application, the safety clamp is installed by attaching the mounting plate to the lower beam of the car and fixing the mounting plate to the lower beam with external fixing bolts, so that the safety clamp can be installed in the lower beam and save the space occupied by the elevator shaft depth.

[0027] 2. In this application, the lifting arm is an integral design. When the external drive component pulls the lifting arm, the lifting arm can simultaneously drive the two wedges, so that the movement of the wedges is synchronized, reducing the phenomenon of unilateral braking failure due to the front-to-back difference in braking of the two wedges, and improving braking synchronization and safety.

[0028] 3. In this application, when the safety clamp needs to be installed on guide rails of different widths, the two adjusting seats can be manually operated to allow the internal components of the adjusting seats to slide between the mounting plate and the connecting plate, thereby moving the two adjusting seats closer to or further apart and adjusting the gap between them according to the width of the guide rail, thus making it easier for the safety clamp to adapt to guide rails of different widths.

[0029] 4. In this application, when the lifting arm drives the wedges, the two wedges move along the tilt direction of the adjusting seat and move towards the guide rail. By pressing against the guide rail with the two wedges, the car can be safely braked. During the movement of the wedges, they contact the guide wheel. The internal components of the guide wheel can reduce the friction generated when the wedges move, thereby improving the smoothness of the wedge movement, reducing the phenomenon of jamming when the wedges move, and thus improving the braking synchronization and safety of the two wedges.

[0030] 5. In this application, when the wedge is reset, the wedge is pulled back and reset by the lifting arm, which can realize the reset of the wedge. During this process, the elasticity of the auxiliary reset component can apply a pull-back force to the lifting arm, which can assist the lifting arm in pulling back and resetting the wedge, improving the smoothness of the wedge reset and maximizing the response speed of the wedge reset action.

[0031] 6. In this application, when the wedge moves along the tilting direction of the adjusting seat, the cleaning component can also be driven simultaneously, so that the internal components of the cleaning component move towards the guide rail and move downward along with the car. The cleaning component can clean the side of the guide rail, thereby cleaning the dust or debris adhering to the side of the guide rail, which can improve the subsequent braking stability of the wedge and reduce the wear generated during wedge braking, thus maximizing braking safety.

[0032] 7. In this application, when using the safety clamp, an external tool can be used to operate the blocking component, causing the internal components of the blocking component to move and extend towards the guide rail, thereby reducing the gap between the internal components of the blocking component and the guide rail, and forming a blocking layer with the mounting plate. This reduces the possibility of external debris entering between the safety clamp and the guide rail and interfering with the braking, further improving braking safety. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 1-10 This application will be described in further detail.

[0036] This application discloses a safety clamp that occupies a small space.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A space-saving safety clamp includes a mounting plate 1, a connecting frame 2 mounted on the bottom of the mounting plate 1, a connecting plate 3 mounted on the bottom end of the connecting frame 2, symmetrical adjusting seats 4 slidably mounted between the mounting plate 1 and the connecting plate 3, symmetrical limiting plates 5 fixedly connected to one side of the adjusting seats 4, forming a slide rail between the two limiting plates 5, a wedge 6 slidably mounted inside the slide rail, a lifting arm 10 rotatably connected to the bottom end of the wedge 6, an auxiliary reset component 12 mounted between the connecting plate 3 and the lifting arm 10, a guide wheel component 7 mounted on the inclined side of the adjusting seat 4, a blocking component 8 mounted on one side inside the mounting plate 1, and symmetrical cleaning components 9 for cleaning the track mounted on the bottom of the connecting plate 3. The wedge 6 and the cleaning component 9 are connected in a transmission manner. Here, the bottom of the wedge 6 is open, and one end of the lifting arm 10 is rotatably connected inside the opening, providing sufficient space for the lifting action of the lifting arm 10.

[0038] When the car experiences uncontrolled descent, sensors inside the car detect the abnormal falling speed in real time and quickly transmit the speed signal to the car's built-in controller. Upon receiving the signal, the controller immediately issues an operation command to the car's braking system, initiating the basic braking program. Simultaneously, the external drive structure pulls the auxiliary reset component 12, which in turn moves the wedge 6 along the slide rail and slides upward in the tilt direction of the adjusting seat 4. This causes the wedge 6 to gradually approach the guide rail, and the two wedges 6 synchronously press against the guide rail side, applying pressure to form a mechanical braking force. This works in conjunction with the car's braking system to achieve dual braking of the uncontrolled car, quickly halting its descent. Furthermore, when using this safety clamp, external tools can be used to manipulate the blocking component 8, causing its internal components to extend towards the guide rail. This reduces the gap between the internal components of the blocking component 8 and the guide rail, forming a blocking layer with the mounting plate 1. This reduces the possibility of external debris entering between the safety clamp and the guide rail, interfering with the braking and further improving braking safety.

[0039] The safety clamp fits snugly against the lower beam of the car via mounting plate 1, and is securely connected to the lower beam using external fixing bolts, achieving overall installation and fixation. This installation method allows the safety clamp to be embedded inside the lower beam of the car, without occupying additional longitudinal space in the elevator shaft, significantly saving shaft depth and making it suitable for space-constrained shaft scenarios.

[0040] The lifting arm 10 in the safety clamp adopts an integral structure design. When the external drive component pulls the lifting arm 10, the lifting arm 10 can synchronously drive the two wedge blocks 6 to move, ensuring that the movement of the wedge blocks 6 on both sides is completely synchronized. This effectively avoids the time difference between the braking of the two wedge blocks 6, prevents the occurrence of unilateral braking failure, and greatly improves the synchronization of the braking process and overall safety.

[0041] For guide rails of different widths, the two adjusting seats 4 can be manually adjusted to achieve a fit. During manual operation, the internal components of the adjusting seats 4 slide relative to each other between the mounting plate 1 and the connecting plate 3, causing the two adjusting seats 4 to move closer or further apart. The distance between them is adjusted according to the actual width of the guide rail, allowing the safety clamp to flexibly adapt to guide rails of various widths and improving the versatility of the safety clamp.

[0042] During the movement of the lifting arm 10 driving the wedge 6 along the tilting direction of the adjusting seat 4, the wedge 6 remains in continuous contact with the guide wheel component 7. The internal components of the guide wheel component 7 replace sliding friction with rolling friction, significantly reducing the friction generated when the wedge 6 moves, improving the smoothness of the wedge 6's movement, avoiding jamming, and further ensuring the synchronicity and reliability of the braking action of the wedges 6 on both sides.

[0043] When the wedge 6 needs to be reset after braking, the lifting arm 10 applies a pull-back force to the wedge 6, causing the wedge 6 to move in the opposite direction to reset. During this process, the auxiliary reset component 12 uses its own elastic properties to apply a reverse pull-back force to the lifting arm 10, assisting the lifting arm 10 in completing the wedge 6 reset action, further improving the smoothness of the reset process and ensuring the response efficiency of the subsequent braking action of the wedge 6.

[0044] When the wedge 6 moves along the tilting direction of the adjusting seat 4, it synchronously drives the cleaning component 9 to move, causing the internal components of the cleaning component 9 to move in the direction of the guide rail. As the car moves downward, the cleaning component 9 cleans the sides of the guide rail, removing dust, debris and other contaminants adhering to the guide rail surface. This ensures the stability of the wedge 6 and the guide rail during braking, reduces wear on both during braking, extends the service life of the components, and improves braking safety.

[0045] Reference Figure 5 and Figure 6 The mounting plate 1 and the connecting plate 3 are provided with corresponding grooves 11. The adjusting seat 4 is slidably installed in the groove 11. The adjusting seat 4 includes a guide block 41 slidably installed between the mounting plate 1 and the connecting plate 3. The upper and lower ends of the guide block 41 are fixedly connected with sliders 42. The sliders 42 are slidably installed inside the groove 11. A threaded slide rod 43 is threadedly connected to one side of the guide block 41. Multiple sets of fixing nuts 44 are threadedly connected to one side of the threaded slide rod 43.

[0046] When adjusting the distance between the two adjusting seats 4, the guide block 41 can be manually pushed so that the guide block 41 drives the slider 42 to slide in the slide groove 11, thereby adjusting the distance between the two guide blocks 41 and the distance between the two wedges 6. This allows the safety clamp to adapt to guide rails of different widths, improving the applicability of the safety clamp. After the position of the guide block 41 is adjusted, multiple sets of fixing nuts 44 can be threadedly connected to the threaded slide rod 43, so that the threaded slide rod 43 and the connecting frame 2 are fixed, thereby adjusting and fixing the adjusting seat 4.

[0047] Reference Figure 7 The auxiliary reset component 12 includes connecting plates 121 that are fixedly connected to the bottom of the connecting plate 3 and the lifting arm 10 respectively. An elastic element is rotatably connected between the two connecting plates 121. The elastic element includes a sleeve rod 122 that is rotatably connected to one side of the connecting plate 121. A tension spring 123 is fixedly connected inside the sleeve rod 122. An inner rod 124 is fixedly connected to one end of the tension spring 123. The inner rod 124 is rotatably connected to the other side of the connecting plate 121.

[0048] When the lifting arm 10 drives the wedge block 6 to reset, the inner rod 124 can be pulled back by the elastic action of the tension spring 123, causing the inner rod 124 to retract and move in the direction of the sleeve rod 122, thereby applying a pull-back force to the lifting arm 10, assisting the lifting arm 10 to reset quickly, and maximizing the response speed of the wedge block 6 reset action.

[0049] Reference Figure 8 The guide wheel component 7 includes a mounting bracket 71 fixedly connected to the inclined side of the guide block 41, and a plurality of guide rollers 72 are rotatably connected to the mounting bracket 71.

[0050] When the wedge 6 moves inside the guide rail, one side of it contacts the guide roller 72. The guide roller 72 can reduce the friction generated when the wedge 6 moves, thereby improving the smoothness of the wedge 6 movement, reducing the phenomenon of jamming when the wedge 6 moves, maximizing the response speed of the subsequent action of the wedge 6, and improving the smoothness of the wedge 6's reset after braking.

[0051] Reference Figure 9 The cleaning component 9 includes a linkage plate 93 symmetrically rotatably connected to the bottom of the connecting plate 3. A brush plate 94 is fixedly connected to one side of the linkage plate 93. Both the guide block 41 and the linkage plate 93 are threadedly connected to threaded limit rods 91. A pull plate 92 is rotatably connected between the two threaded limit rods 91.

[0052] When the wedge 6 moves, it can pull the pull plate 92, which in turn pulls the linkage plate 93, causing the linkage plate 93 to rotate around the rotation point. This, in turn, drives the brush plate 94 to move towards the guide rail, thus cleaning the guide rail and removing dust or debris adhering to the sides of the guide rail. This improves the subsequent braking stability of the wedge 6 and reduces the wear generated during braking, thereby maximizing braking safety.

[0053] Reference Figure 10 The mounting plate 1 has two symmetrical sliding cavities 14 on one side, and a sliding cavity 13 is formed inside the sliding cavity 14. The blocking member 8 includes a baffle 81 that is slidably installed inside the sliding cavity 14. A driving block 82 is fixedly connected to one side of the baffle 81. The driving block 82 is slidably installed inside the sliding cavity 13. A driving member is installed on the two driving blocks 82. The driving member includes a bidirectional threaded rod 83 that is rotatably connected inside the mounting plate 1. The two ends of the bidirectional threaded rod 83 are respectively threaded to the driving block 82. A cross-groove handle 84 is fixedly connected to one end of the bidirectional threaded rod 83.

[0054] The cross-groove handle 84 is driven by an external tool, causing the cross-groove handle 84 to rotate the bidirectional threaded rod 83. The rotating bidirectional threaded rod 83 drives the two drive blocks 82, causing the drive blocks 82 to slide inside the first slide cavity 13 and drive the baffle 81 to slide out from the second slide cavity 14. This causes the baffle 81 to move towards the guide rail, reducing the gap between the baffle 81 and the guide rail and forming a blocking layer with the mounting plate 1. This reduces the possibility of external debris entering between the safety clamp and the guide rail and interfering with the braking, further improving braking safety.

[0055] Working principle: When the car descends out of control, the built-in sensor detects the abnormal speed and immediately transmits the signal to the controller. The controller activates the car braking system. At the same time, the external drive mechanism pulls the auxiliary reset component 12, which drives the wedge 6 to move up the inclined direction along the slide rail and the adjusting seat 4, and move closer to the guide rail. The two wedges 6 synchronously fit against the guide rail and apply compressive force, which works in conjunction with the car braking system to achieve double braking to stop the car from falling.

[0056] The safety clamp is embedded inside the lower beam of the car by fitting the mounting plate 1 with the car lower beam and fastening it with external fixing bolts. This eliminates the need to occupy additional longitudinal space in the hoistway, significantly saving hoistway depth. The lifting arm 10 adopts an integral design, which can synchronously drive the movement of the two wedges 6, avoiding the risk of braking time difference on both sides and unilateral failure, and improving braking synchronization and safety. The two adjusting seats 4 can be manually adjusted so that their internal components slide between the mounting plate 1 and the connecting plate 3. By adjusting the spacing, it can adapt to guide rails of different widths, improving the versatility of the device.

[0057] When the wedge 6 moves, it contacts the guide wheel 7. The guide wheel 7 uses rolling friction instead of sliding friction to reduce resistance, avoid jamming, and ensure braking synchronization and reliability. After braking, the lifting arm 10 drives the wedge 6 to reset. The auxiliary reset component 12 applies a pull-back force with elasticity to assist reset and improve reset smoothness and response efficiency.

[0058] When the wedge 6 moves, it synchronously drives the cleaning component 9 to move along the guide rail. As the car moves down, it cleans the dust and debris on the surface of the guide rail, ensuring braking stability and reducing component wear.
