Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance technology, specifically to an anti-fall support rod for elevator maintenance. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building, with its car moving on at least two rigid tracks that are perpendicular to the horizontal plane or have an angle of inclination of less than 15° to the vertical. An elevator maintenance anti-fall support rod is a passive safety protection device installed on the elevator shaft wall, car door frame, or pit area.

[0003] In existing technologies, as elevators age, regular inspections and maintenance are required to avoid safety hazards during operation. When installing anti-fall bars for traditional elevators, the installation often relies on bolts. Workers must first prepare special tools that perfectly match the bolt type. If the tools are not available on site, the disassembly work will be halted. Even with all the tools, multiple bolts need to be manually tightened repeatedly before installation. This not only involves cumbersome procedures but also requires workers to apply continuous force, making the entire disassembly process time-consuming and labor-intensive, severely slowing down the maintenance progress. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-fall support rod for elevator maintenance, so as to solve the problem mentioned in the background art that the traditional anti-fall rod relies on bolt fixing. When installation is required, not only do you need to prepare special tools with matching models, but you also have to manually tighten multiple sets of bolts repeatedly, which makes the disassembly process cumbersome, time-consuming and laborious, and seriously slows down the maintenance progress.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-fall support rod for elevator maintenance, comprising a mounting frame and a bearing rod, further comprising a wall fixedly connected to one side of the mounting frame and the bearing rod, a support outer rod located on one side of the wall and a mounting seat fixedly connected to one end of the support outer rod, an adjustment component mounted on the support outer rod, a second drive component mounted on the adjustment component, a fixed rod fixedly connected inside the mounting frame, a locking block slidably connected to the fixed rod, a compression spring fixedly connected between the locking block and the mounting frame, and a first drive component mounted on the locking block. The mounting seat is disposed on the mounting frame and the bearing rod, the locking block is engaged with the mounting seat, the locking block is slidably connected to the mounting frame, and the first drive component is used to drive the locking blocks on both sides to move closer or further apart.

[0006] In a preferred embodiment of this technical solution, the mounting bracket is stepped, and the mounting base has a slot at the step of the mounting bracket, with the mounting bracket positioned at the slot of the mounting base.

[0007] In the preferred embodiment of this technical solution, one end of the support rod is set in a conical shape, and the mounting base has an insertion hole at the corresponding position of the support rod, with the support rod set at the insertion port of the mounting base.

[0008] In the preferred embodiment of this technical solution, one end of the card block is set as an arc shape and the other end is set as a straight plate shape. The mounting base contacts the arc end of the card block first, and the mounting base has a slot at the corresponding position of the card block. The card block is engaged with the slot of the mounting base.

[0009] According to the preferred embodiment of this technical solution, the first driving component includes a bracket fixedly connected to the card block at one end, a light rod fixedly connected to the other end of the bracket, a disc fixedly connected to the light rod, a button slidably connected to the mounting bracket, and a moving plate fixedly connected to one end of the button. The light rod is slidably connected to the moving plate, the disc is used to prevent the light rod from detaching from the moving plate, and the button is used to drive the moving plate to perform linear motion.

[0010] Based on the preferred embodiment of this technical solution, two sets of light rods are provided, which are symmetrically distributed on the moving plate. The moving plate has through slots at corresponding positions of the two sets of light rods, and the two sets of light rods are slidably connected to the through slots of the moving plate.

[0011] According to the preferred embodiment of this technical solution, the adjustment component includes a supporting inner rod slidably connected to the supporting outer rod, an anti-slip pad fixedly connected to one end of the supporting inner rod, a rack fixedly connected to one side of the supporting inner rod, a long rod rotatably connected to the supporting outer rod, and a circular gear fixedly connected to one end of the long rod. The circular gear meshes with the rack, and the second drive component is used to drive the long rod to rotate.

[0012] In a preferred embodiment of this technical solution, the second drive assembly includes a protective frame fixedly connected to the outer support rod, a short rod rotatably connected to the protective frame, a rotating handle fixedly connected to one end of the short rod, a first bevel gear fixedly connected to the other end of the short rod, a worm gear rotatably connected to the protective frame, a second bevel gear fixedly connected to one end of the worm gear, and a worm wheel fixedly connected to the other end of the long rod. The second bevel gear meshes with the first bevel gear, the worm gear meshes with the worm wheel, and the rotating handle is used to drive the short rod to rotate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By aligning the support rod with the mounting base, the small stepped end of the mounting bracket can be precisely inserted into the mounting base. Simultaneously, the mounting base first contacts the arc end of the locking block, compressing the compression spring between the locking block and the mounting bracket, and retracting the locking block into the mounting bracket. When both the support rod and the small stepped end of the mounting bracket are inserted to the deepest point of the mounting base, the compression spring automatically rebounds, causing the locking block to engage in the slot of the mounting base, completing the installation of the outer support rod. The entire process requires no additional tools, and the locking blocks on both sides can be moved apart by the first drive component to release the engagement, enabling convenient disassembly of the outer support rod. This effectively simplifies the installation and disassembly process of the outer support rod, significantly improving operational convenience, while ensuring the stability of the outer support rod after installation, preventing loosening after installation from affecting the protective effect, and further ensuring the safety and reliability of elevator maintenance operations.

[0014] 2. The inner support rod of the adjustment component is slidably connected to the outer support rod. The rack on one side of the inner support rod meshes with the circular gear on the long rod. When the second drive component drives the long rod to rotate, the circular gear will drive the rack to move, thereby pushing the inner support rod to extend or retract. This easily achieves the length adjustment of the outer and inner support rods to adapt to elevator doors or shaft spaces of different widths, without the need to replace anti-fall support rods of different lengths. At the same time, the anti-slip pad at one end of the inner support rod increases the friction with the elevator door or shaft wall, preventing the inner support rod from slipping under force after adjustment, ensuring the stability of the anti-fall support, and preventing the protection from failing due to slippage.

[0017] 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.

[0018] Please see Figure 1-5 This utility model provides an embodiment of an elevator maintenance anti-fall support rod, including a mounting frame 21 and a bearing rod 24, and further including a wall 1 fixedly connected to one side of the mounting frame 21 and the bearing rod 24, a supporting outer rod 22 located on one side of the wall 1, a mounting base 23 fixedly connected to one end of the supporting outer rod 22, an adjustment assembly mounted on the supporting outer rod 22, a second drive assembly mounted on the adjustment assembly, a fixing rod 25 fixedly connected inside the mounting frame 21, a locking block 26 slidably connected to the fixing rod 25, a compression spring 27 fixedly connected between the locking block 26 and the mounting frame 21, and a spring mounted on the locking block 26. The first drive assembly has a mounting base 23 mounted on the mounting frame 21 and the support rod 24. A locking block 26 is engaged with the mounting base 23 and slidably connected to the mounting frame 21. The first drive assembly is used to drive the locking blocks 26 on both sides to move closer or further apart. Through the cooperation of the mounting frame 21, the support rod 24 and the mounting base 23, and with the help of the locking blocks 26 and the compression spring 27, quick installation without additional tools can be achieved. The first drive assembly can also easily drive the locking blocks 26 to disengage, simplifying disassembly. The adjustment assembly and the second drive assembly can be adapted to different sizes, which not only improves the flexibility of use, but also ensures the anti-fall effect, and improves maintenance efficiency and safety.

[0019] Please see Figure 3 A further solution based on this embodiment is as follows: the mounting bracket 21 is set in a stepped shape, and the mounting base 23 is provided with a slot at the step of the mounting bracket 21. The mounting bracket 21 is set at the slot of the mounting base 23. By setting the mounting bracket 21 in a stepped shape and opening slots at the corresponding positions of the steps in the mounting base 23, the stepped part of the mounting bracket 21 can accurately match the slot during installation, quickly realizing the positioning of the mounting bracket 21 and the mounting base 23, avoiding left-right offset or up-down misalignment during installation; at the same time, the stepped structure can also increase the contact area between the mounting bracket 21 and the mounting base 23, disperse the pressure transmitted by the outer support rod 22, reduce the wear of a single contact point, and further improve the overall stability of the outer support rod 22 after installation.

[0020] Please see Figure 2A further solution based on this embodiment is as follows: one end of the support rod 24 is set in a conical shape, and the mounting base 23 has an insertion hole at the corresponding position of the support rod 24. The support rod 24 is set at the insertion port of the mounting base 23. By setting one end of the support rod 24 in a conical shape, and matching the insertion hole at the corresponding position of the mounting base 23, the conical end can be inserted into the insertion hole first during installation to play a guiding role. The operator does not need to repeatedly adjust the alignment position of the support rod 24 and the insertion hole, which greatly saves installation time. At the same time, the conical structure can reduce the resistance during insertion. Even in environments with dim lighting or confined space in the shaft, the support rod 24 can be easily inserted into the insertion hole of the mounting base 23, avoiding the reduction of installation efficiency due to insertion difficulties. It can also prevent damage to the support rod 24 or the insertion hole caused by forced insertion, and extend the service life of the components.

[0021] Please see Figure 3 A further solution based on this embodiment is as follows: one end of the locking block 26 is set in an arc shape, and the other end is set in a straight plate shape. The mounting base 23 contacts the arc end of the locking block 26 first, and the mounting base 23 has a corresponding slot on the locking block 26. The locking block 26 is engaged in the slot of the mounting base 23. By setting one end of the locking block 26 in an arc shape, when the mounting base 23 contacts the arc end during installation, it can press the locking block 26 in a smooth manner, avoiding the collision between the edges of the locking block 26 and the mounting base 23, which would cause jamming. This ensures that the mounting bracket 21 can be smoothly inserted into the mounting base 23. Once installed in place, the straight end of the locking block 26 is engaged in the slot of the mounting base 23 under the action of the compression spring 27. The straight plate structure can fit tightly with the slot, preventing the locking block 26 from coming out of the slot when under force, thus ensuring the installation of the support outer rod 22. During subsequent disassembly, the locking block 26 can be moved by the first drive component to disengage from the slot without the need for violent disassembly, which simplifies the disassembly and assembly process and protects the locking block 26 and the slot from damage.

[0022] Please see Figure 3A further solution based on this embodiment is as follows: The first driving component includes a bracket 29 fixedly connected to the locking block 26 at one end, a light rod 210 fixedly connected to the other end of the bracket 29, a disc 211 fixedly connected to the light rod 210, a button 28 slidably connected to the mounting bracket 21, and a moving plate 212 fixedly connected to one end of the button 28. The light rod 210 is slidably connected to the moving plate 212. The disc 211 is used to prevent the light rod 210 from detaching from the moving plate 212. The button 28 is used to drive the moving plate 212 to perform linear motion. The locking block 26 and the light rod 210 are connected by the bracket 29 of the first driving component. The 10-connection system allows the guide rod 210 to slide in conjunction with the moving plate 212. Operators only need to press button 28 to move the moving plate 212 linearly. This, in turn, uses the guide rod 210 and bracket 29 to pull the two side blocks 26 closer together or further apart, eliminating the need for manual prying of the blocks 26. This makes operation easier and is especially suitable for scenarios with limited hand space within the shaft. Simultaneously, the disc 211 is firmly secured to one side of the moving plate 212, preventing the guide rod 210 from detaching from the slot of the moving plate 212 during movement. This avoids drive component failure and ensures stable control of the blocks 26 during each assembly and disassembly, improving operational reliability and safety.

[0023] Please see Figure 3 A further solution based on this embodiment is as follows: Two sets of light rods 210 are provided, and the two sets of light rods 210 are symmetrically distributed on the moving plate 212. The moving plate 212 has through slots at the corresponding positions of the two sets of light rods 210. The two sets of light rods 210 are slidably connected to the through slots of the moving plate 212. By setting two sets of symmetrical light rods 210 and letting them slide and connect to the corresponding through slots of the moving plate 212, when the moving plate 212 moves under the drive of the button 28, the two sets of light rods 210 can synchronously drive the two side blocks 26 to move, avoiding the movement of the block 26 due to the force on one side of the light rod 210, and ensuring that the two side blocks 26 always maintain symmetrical movement. This symmetrical structure can also disperse the force transmitted by the moving plate 212, prevent the single light rod 210 from bending and being damaged due to excessive force, extend the service life of the first drive component, and at the same time allow the block 26 to accurately engage or disengage from the mounting base 23 slot, without affecting the disassembly and assembly effect due to the misalignment of the block 26 on one side.

[0024] Please see Figure 4-5A further solution based on this embodiment is as follows: the adjustment assembly includes an inner support rod 31 slidably connected to the outer support rod 22, an anti-slip pad 33 fixedly connected to one end of the inner support rod 31, a rack 32 fixedly connected to one side of the inner support rod 31, a long rod 310 rotatably connected to the outer support rod 22, and a circular gear 312 fixedly connected to one end of the long rod 310. The circular gear 312 meshes with the rack 32. The second drive assembly is used to drive the long rod 310 to rotate. The inner support rod 31 of the adjustment assembly is slidably connected to the outer support rod 22, and the rack 32 on one side of the inner support rod 31 meshes with the long rod 310. The circular gear 312 on the rod 310 meshes, and when the second drive assembly drives the long rod 310 to rotate, the circular gear 312 will drive the rack 32 to move, thereby pushing the inner support rod 31 to extend or retract, easily realizing the length adjustment of the outer support rod 22 and the inner support rod 31 to adapt to elevator doors or shaft spaces of different widths, without the need to replace anti-fall support rods of different lengths; at the same time, the anti-slip pad 33 at one end of the inner support rod 31 can increase the friction with the elevator door or shaft wall, preventing the inner support rod 31 from slipping when under force after adjustment, ensuring the stability of the anti-fall support, and preventing the protection from failing due to slippage.

[0025] Please see Figure 5 A further solution based on this embodiment is as follows: The second drive assembly includes a protective frame 34 fixedly connected to the supporting outer rod 22, a short rod 35 rotatably connected to the protective frame 34, a rotating handle 36 fixedly connected to one end of the short rod 35, a first bevel gear 37 fixedly connected to the other end of the short rod 35, a worm gear 38 rotatably connected to the protective frame 34, a second bevel gear 39 fixedly connected to one end of the worm gear 38, and a worm wheel 311 fixedly connected to the other end of the long rod 310. The second bevel gear 39 meshes with the first bevel gear 37, the worm gear 38 meshes with the worm wheel 311, and the rotating handle 36 is used to drive the short rod 35 to rotate. The rotating handle 36 of the second drive assembly drives the short rod 35 to rotate. The lever 35 drives the first bevel gear 37 to mesh with the second bevel gear 39, which in turn causes the worm 38 to rotate and mesh with the worm wheel 311, ultimately driving the long rod 310 to rotate. The transmission structure of the bevel gears and the worm 38 and worm wheel 311 can amplify the force. The operator only needs to turn the handle 36 to drive the long rod 310, making the operation more labor-saving and eliminating the need for special tools such as wrenches. This is especially suitable for maintenance personnel to operate with one hand. At the same time, the protective frame 34 can cover the first bevel gear 37, worm 38, worm wheel 311 and other components to prevent oil and dust in the wellbore from adhering to the transmission components and causing wear or jamming. Moreover, the meshing of the worm 38 and worm wheel 311 has a self-locking characteristic, and no additional fixing structure is required after adjustment.

[0026] Working principle: First, the installation operation is performed. The mounting bracket 21 and the support rod 24 are fixed on one side of wall 1. The operator aligns the mounting seat 23 at one end of the supporting outer rod 22 with the bracket. At this time, the stepped shape of the mounting bracket 21 allows for precise insertion into the corresponding slot of the mounting seat 23, and the stepped shape limits the insertion stroke. The tapered end of the support rod 24 first extends into the insertion hole of the mounting seat 23 to act as a guide. During insertion, the mounting seat 23 first contacts the arc end of the locking block 26, pressing the compression spring 27 between the locking block 26 and the mounting bracket 21, causing the locking block 26 to slide along the fixing rod 25 into the mounting bracket 21. When both the stepped end of the mounting bracket 21 and the support rod 24 are inserted to the deepest point of the mounting seat 23, the compression spring 27 rebounds, pushing the straight end of the locking block 26 into the slot of the mounting seat 23, completing the fixed installation of the supporting outer rod 22. If it is necessary to adapt to elevator doors or shaft spaces of different widths, the length can be adjusted through the second drive component: rotating the rotating handle 36 on the protective frame 34 drives the short rod 3... 5 drives the first bevel gear 37 to rotate, which meshes with the second bevel gear 39 to drive the worm 38 to rotate. The worm 38 then meshes with the worm wheel 311 at the other end of the long rod 310, causing the long rod 310 to rotate. The circular gear 312 at one end of the long rod 310 rotates accordingly and meshes with the rack 32 on one side of the inner support rod 31, pushing the inner support rod 31 to slide out or retract along the outer support rod 22. The anti-slip pad 33 at one end of the inner support rod 31 can increase the friction with the contact parts, and the worm 38 and worm wheel... 311 engagement has a self-locking characteristic, and no additional fixing is required after adjustment; when disassembling after maintenance, press the button 28 on the mounting bracket 21 to drive the moving plate 212 to move linearly. The moving plate 212 pulls the two side locking blocks 26 closer to each other along the fixed rod 25 through two sets of symmetrical light rods 210 (the disc 211 prevents the light rods 210 from disengaging) and the bracket 29, compressing the spring 27 and causing the locking blocks 26 to disengage from the mounting base 23 slot. Then the outer support rod 22 can be removed to complete the entire operation process.
