Description

Technical Field

[0001] This utility model relates to the field of attached lifting scaffolding, specifically to a wall mount suitable for two types of fall arresters and a fall arrester having the wall mount. Background Technology

[0002] Attached lifting scaffolding refers to scaffolding erected to a certain height and attached to the building structure via attachment supports. It relies on its own lifting mechanism to rise and fall layer by layer with the building structure, providing functions such as safety protection, anti-overturning, anti-falling, and synchronous control. Existing attached lifting scaffolding includes a frame, wall supports, and fall arresters, with the fall arresters installed on the wall supports. Existing fall arresters are mainly divided into two types: pendulum fall arresters and rotating wheel fall arresters. The pendulum fall arrester includes a fall arresting block and a stop block. It does not jam when the lifting frame is raised, but due to processing and construction environment, the fall arrester may fail to trigger during lifting, leading to a safety hazard. Furthermore, it may falsely trigger during descent, causing the fall arrester to be ineffective and unable to descend. The rotating wheel fall arrester includes a rotating wheel and a rotating wheel trigger block. It does not jam, but disassembly and assembly are more complicated. Furthermore, each type of fall arrestor is only compatible with a specific wall-mounted support. When the fall arrestor needs to be replaced due to changes in the construction environment, the original wall-mounted support must be disassembled and replaced, which increases enterprise costs and reduces the turnover efficiency of material management. In addition, existing pendulum fall arrestors all use a tension spring to ensure the pendulum returns to its original position. However, after prolonged use, the tension spring is prone to failure or rust, affecting the pendulum's return to its original position and creating a safety hazard. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, the purpose of this utility model is to provide a wall-mounted bracket applicable to two types of fall arresters and a fall arrester with the wall-mounted bracket, thereby solving the problem that existing wall-mounted brackets for attached lifting scaffolds have poor versatility, can only be used for one type of fall arrester, and require the replacement of the other wall-mounted bracket when replacing the fall arrester, increasing enterprise costs and reducing material management turnover efficiency. In addition, existing pendulum fall arresters all use a tension spring for reset, which can easily lead to safety hazards after long-term use.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A wall mount suitable for two types of fall arresters includes a base body. Two mounting plates for mounting fall arresters are spaced apart in the middle of the base body. Each mounting plate has corresponding mounting holes for a pendulum block and rotating wheel, a rotating wheel trigger block, and a pendulum pin stop pin. These mounting holes are arranged in a triangular pattern. The rotating wheel trigger block mounting hole is positioned between the pendulum block and rotating wheel mounting holes and the pendulum pin stop pin mounting hole, while the pendulum pin stop pin mounting hole is located on top of the pendulum block and rotating wheel mounting holes. The pendulum block and rotating wheel mounting holes are located near the outer side of the mounting plates and are used to mount the rotating shaft of the pendulum fall arrester and the rotating wheel of the rotating wheel fall arrester. This creates a space between the two mounting plates for mounting the fall arresters. The mounting plates have mounting holes for the pendulum main body and stop pin of the pendulum fall arrester, and also mounting holes for the rotating wheel and rotating wheel trigger block of the rotating wheel fall arrester. The mounting holes for the pendulum main body and the rotating wheel are the same. The mounting holes for the swing block and rotating wheel are located at the front end of the mounting hole (i.e., near the outer side of the mounting plate). This allows the outer portion of the rotating wheel and swing needle body (anti-fall block) to extend beyond the mounting plate after installation, contacting the anti-fall stop bar on the anti-fall slide rail outside the mounting plate. This allows the anti-fall stop bar to actuate the swing needle body or rotating wheel when the anti-fall slide rail is raised or lowered. The mounting holes for the rotating wheel trigger block and the swing needle stop pin are located on the inner side, corresponding to their respective installation positions. In application, if a different anti-fall device needs to be installed depending on the installation environment, the existing anti-fall device can be quickly replaced by removing it from the wall mount without disassembling the wall mount. This convenient replacement eliminates the need to purchase a separate wall mount, effectively saving costs.

[0005] Furthermore, the base includes a wall-mounted plate and a left and right side plate vertically fixed to the left and right sides of the wall-mounted plate. The inner ends of the two mounting plates are welded and fixed to the wall-mounted plate, located between the left and right side plates. A horizontally arranged reinforcing plate is also fixed to the two mounting plates, and the left and right ends of the reinforcing plate are welded and fixed to the left and right side plates, respectively. In this way, the two mounting plates are welded and fixed to the wall-mounted plate of the base, ensuring a stable installation. The reinforcing plate on the fixed plate can effectively increase the impact resistance of the mounting plate when subjected to external forces.

[0006] Furthermore, both the left and right side plates are composed of a rotating wheel mounting part, a trapezoidal connecting part, and an inner mounting plate. The trapezoidal connecting part is positioned between the rotating wheel mounting part and the inner mounting plate, and the length of the trapezoidal connecting part closer to the mounting part is shorter than the length of the side closer to the inner mounting plate. The lower end of the mounting plate near the wall-mounted plate is inclined, forming a space for wall bolt assembly with the wall-mounted plate. Thus, after the left and right side plates are installed, the middle section is trapezoidal, meaning the upper and lower sides of the left and right side plates are inclined, exposing the mounting plate portion located between the left and right side plates. This ensures unobstructed side installation of various components on the fall arrestor, making installation and disassembly more convenient.

[0007] A fall arrestor with a wall mount includes a wall mount and a pendulum fall arrestor mounted on the wall mount. The wall mount is as described above. The pendulum fall arrestor includes a fall arrestor pendulum assembly and a pendulum stop pin. The fall arrestor pendulum assembly is positioned between two mounting plates of the wall mount and includes a fall arrestor block, a pendulum trigger block, and a first rotating shaft. The middle portion of the fall arrestor block and one end of the pendulum trigger block are both fitted onto the first rotating shaft, allowing rotatable mounting between the two mounting plates via the first rotating shaft. The center of gravity of the fall arrestor block is located at its lower end, and its outer portion extends beyond the mounting plate. One side of the pendulum trigger block extends outward to form an angled trigger portion, and the end of the trigger portion extends beyond the end of the fall arrestor block. The pendulum trigger... When the anti-fall rail is slowly raised, the trigger part contacts the anti-fall stop bar on the anti-fall rail and rotates back to its original position. When the anti-fall rail is slowly lowered, the trigger part contacts the anti-fall stop bar on the anti-fall rail and rotates counterclockwise. The lower end of the rotating end abuts against the anti-fall swing block, causing the anti-fall swing block to rotate synchronously. Under the action of its own weight, the anti-fall swing block quickly returns to its original position. The swing stop pin is located on one side of the anti-fall swing pin assembly. When the anti-fall rail falls and the anti-fall swing block and the swing trigger block rotate synchronously to the horizontal position, the inner side of the anti-fall swing block abuts against the swing stop pin, together with the anti-fall stop bar at the same height as the swing stop pin, to prevent the anti-fall swing block from continuing to rotate. In this way, the center of gravity of the anti-fall swing block of the swing pin anti-fall assembly is at the lower end. Therefore, after being turned by the anti-fall stop bar, it will return to its original position under its own weight, thus eliminating the need for a tension spring and avoiding safety problems caused by tension spring failure or rust. Meanwhile, the pendulum anti-fall assembly mainly consists of an anti-fall pendulum block and a pendulum trigger block, both of which are rotatably mounted between the mounting plates via a first rotating shaft. The outer side of the pendulum trigger block extends beyond the mounting plate and is angular, thus bringing its center of gravity close to the first rotating shaft. This allows it to return to its original position under its own weight after being deflected by the anti-fall stop lever. Both the anti-fall pendulum block and the pendulum trigger block have low centers of gravity, and the pendulum trigger block extends further out, ensuring that the anti-fall slide rail contacts the pendulum trigger block first during lifting or lowering, causing the pendulum trigger block to reciprocate. When the anti-fall slide rail is raised, the pendulum trigger block rotates clockwise. When the anti-fall slide rail is lowered, the pendulum trigger block rotates counterclockwise. After rotating counterclockwise to a certain angle, the lower end can contact the anti-fall pendulum block, pushing the anti-fall pendulum block to rotate a certain angle. If the descent speed is fast, the pendulum trigger block will be subjected to greater force, making it impossible for the pendulum trigger block and the anti-fall pendulum block to return to their original positions in time. This will push the anti-fall pendulum block to continue rotating until it reaches a horizontal position. At this point, the anti-fall pendulum block will abut against the pendulum stop pin and the anti-fall stop bar at the same height, locking itself in the current position and achieving the stop positioning of the anti-fall slide rail to prevent further descent.

[0008] Furthermore, a weight-reducing groove is provided in the middle of the upper end of the fall-prevention pendulum block. The upper end and outer side of the weight-reducing groove have openings. The pendulum trigger block is placed inside the weight-reducing groove, and a contact surface that mates with the bottom of the weight-reducing groove is provided at the lower end of the pendulum trigger block. In this way, the weight of the simulated pendulum block is reduced by the weight-reducing groove, lowering its center of gravity. Placing the pendulum trigger block inside the weight-reducing groove facilitates contact between the pendulum needle and the bottom of the fall-prevention pendulum block groove when the fall-prevention slide rail descends, causing the fall-prevention pendulum block to rotate. This design not only lowers the center of gravity of the fall-prevention pendulum block but also results in a compact structure.

[0009] Furthermore, the upper end of the anti-fall pendulum block is a right-angled triangle with an inclined surface on the outside. In this way, the outer side of the upper end of the anti-fall pendulum block corresponding to the weight reduction groove is inclined, which can further reduce the weight of the upper end of the anti-fall pendulum block and facilitate the exposure of the end of the pendulum trigger block.

[0010] Furthermore, the pendulum trigger block is provided with a sleeve hole that mates with the first rotating shaft, and the anti-fall pendulum block is provided with a through hole for the first rotating shaft to pass through. In this way, the sleeve hole facilitates the fitting of the pendulum trigger block, and the through hole on the pendulum block also facilitates the passing of the first rotating shaft.

[0014] Attached lifting scaffolding can be vertically raised and lowered along the facade of a building to accommodate construction needs at different heights. Wall anchors are a crucial component of attached lifting scaffolding, comprising the wall anchor itself and the fall arrestor installed within it. Currently, conventional wall anchors can only accommodate one type of fall arrestor, while there are typically two types: pendulum fall arrestors and wheel fall arrestors. Each type corresponds to a specific wall anchor, resulting in poor versatility. Furthermore, the existing pendulum fall arrestors' fall arrestor levers (equivalent to the fall arrestor pendulum assembly in this embodiment) are connected to a tension spring. After the fall arrestor lever rotates, the spring returns it to its initial position. Tension springs are prone to failure after prolonged use, and being exposed to wind and rain on the building facade, they are susceptible to rust, posing a safety hazard.

[0015] like Figures 1-2 As shown, this embodiment provides a wall mount 1 suitable for two types of fall arresters, including a base body. Two mounting plates 14 for mounting fall arresters are installed at intervals in the middle of the base body. Each mounting plate 14 is equipped with a corresponding pendulum block and wheel mounting hole 15, a wheel trigger block mounting hole 16, and a pendulum needle stop pin 17 mounting hole. The pendulum block and wheel mounting holes 15, the wheel trigger block mounting hole 16, and the pendulum needle stop pin 17 mounting holes are triangularly distributed. The wheel trigger block mounting hole 16 is located between the pendulum block and wheel mounting hole 15 and the pendulum needle stop pin 17 mounting hole, and the pendulum needle automatic pin mounting hole is located on the pendulum block and wheel mounting hole 15. The pendulum block and wheel mounting hole 15 is located near the outer side of the mounting plate 14 and is used to install the pendulum needle fall arrester's shaft and the wheel of the wheel fall arrester. Thus, a space for installing the fall arrester is formed between the two mounting plates 14. Mounting plates 14 have mounting holes for the pendulum needle body and stop pin of the pendulum fall arrester, and mounting holes for the rotating wheel and rotating wheel trigger block of the rotating wheel fall arrester. The mounting holes for the pendulum needle body and the rotating wheel are the same. The mounting holes 15 for the pendulum needle body and the rotating wheel are located at the front end of the mounting holes (i.e., near the outer side of the mounting plate 14), allowing the outer portion of the rotating wheel and pendulum needle body (fall arrestor block) to extend beyond the mounting plate 14 after installation and contact the fall arrestor stop bar on the fall arrestor slide rail outside the mounting plate 14. This allows the fall arrestor stop bar to actuate the pendulum needle body or the rotating wheel when the fall arrestor slide rail is raised or lowered. The mounting holes 16 for the rotating wheel trigger block and 17 for the pendulum needle stop pin are both located on the inner side, corresponding to the installation positions of the rotating wheel trigger block and the automatic pin of the pendulum needle. In application, if it is necessary to replace it with another fall arrestor according to the installation environment, the existing fall arrestor on the wall mount 1 can be removed and replaced quickly without removing the wall mount 1. The replacement is more convenient and there is no need to purchase a separate wall mount 1, which effectively saves costs.

[0016] Furthermore, the base includes a wall-mounted plate 11 and a left side plate 12 and a right side plate 13 vertically fixed to the left and right sides of the wall-mounted plate 11. Two mounting plates 14 are welded and fixed to the wall-mounted plate 11 at their inner ends, located between the left side plate 12 and the right side plate 13. A horizontally arranged reinforcing plate 18 is also fixed to the two mounting plates 14, with its left and right ends welded and fixed to the left side plate 12 and the right side plate 13, respectively. In this way, the two mounting plates 14 are welded and fixed to the wall-mounted plate 11 of the base, ensuring a stable installation. The reinforcing plate on the fixing plate effectively increases the impact resistance of the mounting plate 14 when subjected to external forces.

[0017] Furthermore, both the left side plate 12 and the right side plate 13 are composed of a rotating wheel mounting part, a trapezoidal connecting part, and an inner mounting plate 14. The trapezoidal connecting part is located between the rotating wheel mounting part and the inner mounting plate 14, and the length of the trapezoidal connecting part near the mounting part is less than the length of the side near the inner mounting plate 14. The lower end of the mounting plate 14 near the wall-mounted plate 11 is inclined, forming a space for wall bolt assembly with the wall-mounted plate 11. In this way, after the left side plate 12 and the right side plate 13 are installed, the middle part is trapezoidal, that is, the upper and lower sides of the left side plate 12 and the right side plate 13 are inclined, so that the mounting plate 14 located between the left and right side plates 13 is partially exposed, thus there is no obstruction on the sides when installing various components on the fall arrestor, making installation and disassembly more convenient.

[0018] The structure for installing the pendulum fall arrestor using the wall mount in this embodiment is as follows: Figure 3 As shown in the figure, the installation structure of the wall-mounted wheel fall arrestor in this embodiment is as follows: Figure 4 As shown. Specifically, the rotating wheel fall arrestor used is a conventional rotating wheel simulator, including a rotating wheel and a rotating wheel trigger block. The operating principle and process of this rotating wheel fall arrestor are the same as those of existing technologies, and for details, please refer to the rotating wheel pendulum integrated fall arrestor disclosed in Chinese Patent Publication No. 213626604.

[0019] like Figure 3 , Figures 5-9 As shown, this embodiment also provides a fall arrestor using the aforementioned wall mount 1, including the wall mount 1 and a pendulum fall arrestor mounted on the wall mount 1. The pendulum fall arrestor includes a fall arrestor pendulum assembly and a pendulum stop pin 5. The fall arrestor pendulum assembly is placed between the two mounting plates 14 of the wall mount 1 and includes a fall arrestor pendulum block 2, a pendulum trigger block 3, and a first rotating shaft 4. The middle part of the fall arrestor pendulum block 2 and one end of the pendulum trigger block 3 are both fitted onto the first rotating shaft 4, and are rotatably mounted between the two mounting plates 14 via the first rotating shaft 4 (i.e., the end of the first rotating shaft 4 is correspondingly mounted at the pendulum block and the rotating wheel mounting hole on the same side). The center of gravity of the fall arrestor pendulum block 2 is located at the lower end, and the outer part extends out of the mounting plate 14. One side of the pendulum trigger block 3 extends outward to form an angled trigger part 31, and the end of the trigger part 31 extends out of the end of the fall arrestor pendulum block 2. Figure 7 As shown, the pendulum trigger block 3 can reciprocate and return to its original position after the trigger part 31 contacts the anti-fall stop bar 81 on the anti-fall slide rail 8 when the anti-fall slide rail 8 is slowly raised; as Figure 8 As shown, when the anti-fall slide rail 8 slowly descends, the triggering part 31 contacts the anti-fall stop bar 81 on the anti-fall slide rail 8 and rotates counterclockwise. The lower end face of the rotating part then abuts against the anti-fall swing block 2, causing the anti-fall swing block 2 to rotate synchronously. Under the weight of its own body, the swing block 2 quickly returns to its original position. Figure 9 As shown, the pendulum stop pin 5 is located on one side of the anti-fall pendulum assembly. When the anti-fall slide rail 8 falls, and the anti-fall pendulum block 2 and the pendulum trigger block 3 rotate synchronously to a horizontal position, the inner side of the anti-fall pendulum block 2 abuts against the pendulum stop pin 5, together with the anti-fall stop bar 81 at the same height as the pendulum stop pin 5, preventing the anti-fall pendulum block 2 from continuing to rotate. In this way, the center of gravity of the anti-fall pendulum block 2 of the pendulum anti-fall assembly is at the lower end. Therefore, after being turned by the anti-fall stop bar 81, it will return to its original position under its own weight, thus eliminating the need for a tension spring and avoiding safety problems caused by tension spring failure or rust. Meanwhile, the pendulum anti-fall assembly mainly consists of an anti-fall pendulum block 2 and a pendulum trigger block 3, both of which are rotatably mounted between the mounting plates 14 via the first rotating shaft 4. The outer side of the pendulum trigger block 3 extends out of the mounting plate and is pointed, so that the center of gravity of the pendulum trigger block 3 is close to the first rotating shaft 4, allowing it to return to its original position under its own weight after being pushed by the anti-fall stop lever 81. The centers of gravity of both the anti-fall pendulum block 2 and the pendulum trigger block 3 are both low, and the end of the pendulum trigger block 3 extends further, so that the anti-fall slide rail 8 contacts the pendulum trigger block 3 first when lifting or lowering, causing the pendulum trigger block 3 to reciprocate. When the anti-fall slide rail 8 is raised, the pendulum trigger block 3 rotates clockwise. When the anti-fall slide rail 8 is lowered, the pendulum trigger block 3 rotates counterclockwise. After rotating counterclockwise to a certain angle, the lower end can contact the anti-fall pendulum block 2, pushing the anti-fall pendulum block 2 to rotate a certain angle. If the descent speed is fast, the pendulum trigger block 3 will be subjected to greater force, so that the pendulum trigger block 3 and the anti-fall pendulum block 2 cannot return to their original positions in time, pushing the anti-fall pendulum block 2 to continue rotating until it rotates to a horizontal position. The anti-fall pendulum block 2 then abuts against the pendulum stop pin 5 and the anti-fall stop bar 81 at the same height, locking in the current position, thereby stopping and positioning the anti-fall slide rail 8 and preventing it from falling further.

[0020] Furthermore, a weight-reducing groove 21 is provided in the middle of the upper end of the fall-prevention pendulum block 2. The weight-reducing groove 21 has openings at its upper end and outer side. The pendulum trigger block 3 is placed inside the weight-reducing groove 21, and a contact surface 33 that mates with the bottom of the weight-reducing groove 21 is provided at the lower end of the pendulum trigger block 3. In this way, the weight of the simulated pendulum block is reduced by setting the weight-reducing groove 21, causing its center of gravity to shift downward. Placing the pendulum trigger block 3 inside the weight-reducing groove 21 facilitates the contact between the pendulum and the bottom of the groove of the fall-prevention pendulum block 2 when the fall-prevention slide rail 8 descends, thereby driving the fall-prevention pendulum block 2 to rotate. This structure not only lowers the center of gravity of the fall-prevention pendulum block 2 but also has a compact structure.

[0021] In specific implementation, without considering structural compactness, the pendulum trigger block 3 can be set on one side of the anti-fall pendulum block 2, and a protrusion that cooperates with the lower contact surface 33 of the pendulum trigger block 3 can be set on the simulated pendulum block. The protrusion is below the pendulum trigger block 3 and can contact the contact surface 33 of the pendulum trigger block 3 after the pendulum trigger block 3 is rotated counterclockwise to a certain angle.

[0022] Furthermore, the upper end of the anti-fall pendulum block 2 is a right-angled triangle, and the outer side is a slope. In this way, the outer side of the upper end of the anti-fall pendulum block 2 corresponding to the weight reduction groove 21 is a slope, which can further reduce the weight of the upper end of the anti-fall pendulum block 2 and facilitate the exposure of the end of the pendulum trigger block 3.

[0023] Furthermore, the pendulum trigger block 3 is provided with a sleeve hole 32 that mates with the first rotating shaft 4, and the anti-fall pendulum block 2 is provided with a through hole for the first rotating shaft 4 to pass through. In this way, the sleeve hole 32 facilitates the fitting of the pendulum trigger block 3, and the through hole on the pendulum block also facilitates the passing of the first rotating shaft 4.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
