Description

Technical Field

[0001] This invention relates to the field of roof construction and maintenance, specifically to a metal roof anti-slip walking device that facilitates on-site inspection. Background Technology

[0002] Metal roofing refers to a roofing system that uses metal sheets as the roofing material, combining the structural layer and the waterproofing layer into one. It is widely used in large public buildings, industrial plants, warehouses, and other places. With the popularization of steel structure buildings, metal roofing systems need to be inspected and maintained in a timely manner after extreme weather such as typhoons. However, walking directly on the metal roof panels can easily damage the roof structure and threaten the personal safety of maintenance personnel. Therefore, installing walking devices on metal roofs for maintenance personnel has become a necessary measure to ensure the safety of the roof and personnel.

[0003] Currently, metal roof inspection and walking devices are mainly divided into two categories: one is a fixed inspection walkway, which forms a fixed passage by laying aluminum square tubes and walkway panels on the roof; the other is a temporary inspection walkway, which uses detachable walkway panels and is fixed to the roof edge with clamps. However, existing devices still have many shortcomings in actual use, including poor stability when walking on the roof and increased danger when there is a lot of dust on the roof. Therefore, there is an urgent need for a metal roof anti-slip walking device that is easy to use for on-site inspection and maintenance. Summary of the Invention

[0004] The purpose of this invention is to provide a metal roof anti-slip walking device that is easy to inspect and maintain on-site, in order to solve the problems of poor stability when walking on the roof and increased danger when there is a lot of dust on the roof.

[0006] The anti-slip component includes a fixing belt with a tightening belt at the front end. The bottom end of the walking base plate is connected to a side friction block. Both ends of the bottom of the walking base plate are also provided with end friction blocks. There are two sets of side friction blocks. The end friction blocks are located at the front and rear ends of the walking base plate. The side of the walking base plate is provided with a sliding groove.

[0007] The positioning component includes a delivery pipe with a negative pressure suction cup at its bottom end and a connecting pipe connected to one side of the delivery pipe. A connecting end is connected to the top of the connecting pipe, and a cylinder is installed at the top of the connecting end. A flexible hose is provided on one side of the connecting end. An air pump is installed inside the walking base plate. There are three sets of negative pressure suction cups. The two ends of the flexible hose are detachably connected to the connecting pipe and the air pump, respectively. The connecting pipe is connected to the delivery pipe, and the delivery pipe is movably connected to the cylinder through the connecting end.

[0008] The cleaning assembly includes a support plate, a servo motor is installed inside the support plate, a balance plate is provided at the output end of the servo motor, a drive ring is connected to the outside of the balance plate, a rotating seat is provided at the bottom end of the drive ring, a movable rod is connected to the rotating seat, a cleaning brush is provided on the outer wall of the movable rod, there are multiple movable rods, and the movable rods are movably connected to the rotating seat through a connecting ring, and the drive ring is rotatably connected to the servo motor through the balance plate.

[0009] Preferably, a battery is installed inside the walking base plate, and a charging hole is provided on the walking base plate. The battery is electrically connected to the cylinder and the air pump through a power line.

[0010] Preferably, the fixing belt and the tightening belt are fixedly connected to the walking base plate, and the walking base plate is made of polyethylene.

[0011] Preferably, the side friction blocks and the two end friction blocks are made of rubber, and a sliding cable head is embedded in the inner side of the sliding groove, and the sliding cable head and the sliding groove are movably connected by a pulley.

[0012] Preferably, the rear end of the walking base plate is provided with an air hole that matches the air pump, and the cylinder and the walking base plate are fixedly installed by a mounting bracket.

[0013] Preferably, the negative pressure suction cup is connected to the conveying pipe, a storage box is fixed on one side of the walking base plate, a remote control is provided inside the storage box, and the remote control is electrically connected to the air pump through a PLC controller.

[0014] Preferably, the support plate and the support base are adjustable and fixed by damping and a rotating shaft. The support plate is equipped with a corresponding battery, and the battery inside the support plate is electrically connected to the servo motor through a power line.

[0015] Preferably, the balance plate and the servo motor are fixedly connected via a connecting shaft.

[0016] Preferably, the movable rod and cleaning brush are made of flexible ABS plastic.

[0017] Compared with the prior art, the beneficial effects of the present invention are: First, this invention, by setting up a walking base plate, side friction blocks, and end friction blocks, allows maintenance personnel to place their feet between the fixing straps and tightening straps on the walking base plate. The tightening straps secure the feet to the walking base plate, ensuring that the walking base plate moves synchronously with the feet. The side friction blocks and end friction blocks are made of rubber and are in direct contact with the metal roof surface. When walking, the weight of the human body is compressed by the walking base plate against the side friction blocks and end friction blocks, causing them to adhere tightly to the roof surface after being subjected to force. The friction between the friction blocks and the roof panel provides basic anti-slip resistance, preventing maintenance personnel from slipping when walking on the sloping roof.

[0018] Secondly, this invention incorporates an air pump, cylinder, negative pressure suction cups, and delivery pipe. Maintenance personnel issue control commands via a remote control housed in a storage box on one side of the walking platform. The remote control is electrically connected to the air pump and cylinder via a PLC controller. Upon receiving the start signal, the cylinder drives the delivery pipe downwards through its connecting end. Three sets of negative pressure suction cups at the bottom of the delivery pipe move downwards synchronously and adhere tightly to the surface of the metal roof panel. Once the suction cups are in place, the air pump starts, extracting air from inside the suction cups through hoses, connecting pipes, and the delivery pipe, creating a negative pressure environment inside the suction cups. Under the influence of external atmospheric pressure, the suction cups are firmly adhered to the surface of the metal roof panel, thus fixing the walking platform relative to the roof panel and providing stable support for maintenance personnel to stand and work.

[0019] Third, this invention, by setting up a servo motor, drive ring, movable rods, and cleaning brushes, allows the maintenance personnel to start the power supply of the battery inside the support plate before walking. The servo motor is powered on and starts. The output end of the servo motor is fixedly connected to the balance plate through the connecting shaft, driving the balance plate to rotate around its axis. The drive ring rotates synchronously with the balance plate. During rotation, the rotating seat and connecting ring drive multiple movable rods to unfold outward. Each movable rod has a cleaning brush on its outer wall. When the drive ring rotates, the rotating seat drives multiple movable rods and cleaning brushes to make circular motion around the axis of the drive ring. Each movable rod unfolds outward under the action of centrifugal force, so that the cleaning brush contacts and cleans the roof panel surface in front of the walking base plate with a certain pressure, so as to enhance the friction between the side friction blocks, the friction blocks at both ends and the roof, thereby improving the stability of the walking device on the roof.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-4A metal roof anti-slip walking device for easy on-site maintenance includes a walking base plate 1, an anti-slip component 2 mounted on the walking base plate 1, a positioning component 3 mounted at the bottom end of the walking base plate 1, a support base 5 mounted at the front end of the walking base plate 1, a cleaning component 6 mounted on the support base 5, the anti-slip component 2 including a fixing strap 201, a tightening strap 202 mounted at the front end of the fixing strap 201, a side friction block 203 connected to the bottom end of the walking base plate 1, and two end caps mounted at both ends of the bottom of the walking base plate 1. The friction blocks 204 and the side friction blocks 203 are in two sets. The friction blocks 204 at both ends are located at the front and rear ends of the walking base plate 1. The side of the walking base plate 1 has a sliding groove 205. The walking base plate 1 has a battery 4 installed inside and a charging hole. The battery 4 is electrically connected to the cylinder 306 and the air pump 307 through a power cord. The fixing strap 201 and the tightening strap 202 are fixedly connected to the walking base plate 1. The walking base plate 1 is made of polyethylene. The side friction blocks 204 and 205 are in two sets. 3. The friction blocks 204 at both ends are made of rubber. A sliding cable head 206 is embedded inside the sliding groove 205, and the sliding cable head 206 is movably connected to the sliding groove 205 via pulleys. Maintenance personnel place their feet between the fixing strap 201 and the tightening strap 202 on the walking base plate 1, respectively. The tightening strap 202 secures the feet to the walking base plate 1, ensuring that the walking base plate 1 moves synchronously with the feet. The bottom of the walking base plate 1 is equipped with side friction blocks 203 and two end friction blocks 204, among which the two... The side friction blocks 203 are located on the left and right sides of the walking base plate 1, and the end friction blocks 204 are located at the front and rear ends of the walking base plate 1. The three sets of friction blocks are made of rubber and are in direct contact with the metal roof surface. When walking, the weight of the human body is squeezed by the walking base plate 1 to the side friction blocks 203 and end friction blocks 204, so that they are tightly attached to the roof after being subjected to force. The friction between the friction blocks and the roof panel provides basic anti-slip resistance to prevent maintenance personnel from slipping when walking on the sloping roof.

[0024] Please see Figure 5-8A metal roof anti-slip walking device for easy on-site maintenance, the positioning component 3 includes a conveying pipe 301, a negative pressure suction cup 303 at the bottom end of the conveying pipe 301, a connecting pipe 302 connected to one side of the conveying pipe 301, a connecting end 305 connected to the top end of the connecting pipe 302, a cylinder 306 installed at the top end of the connecting end 305, and a flexible hose 304 provided on one side of the connecting end 305. An air pump 307 is installed inside the walking base plate 1, and the number of negative pressure suction cups 303 is three. The assembly consists of a flexible hose 304, with both ends detachably connected to a connecting pipe 302 and a vacuum pump 307, respectively. The connecting pipe 302 is connected to a conveying pipe 301, and the conveying pipe 301 is movably connected to a cylinder 306 via a connecting end 305. The rear end of the walking base plate 1 has an air hole matching the vacuum pump 307. The cylinder 306 is fixedly mounted to the walking base plate 1 via a mounting bracket. A negative pressure suction cup 303 is connected to the conveying pipe 301. A storage box 308 is fixed to one side of the walking base plate 1. A remote control 309 is installed inside the 8. The remote control 309 is electrically connected to the air pump 307 via a PLC controller. Maintenance personnel can issue control commands through the remote control 309, which is located in the storage box 308 on one side of the walking base plate 1. The remote control 309 is electrically connected to the air pump 307 and the cylinder 306 via the PLC controller. After receiving the start signal, the cylinder 306 drives the delivery pipe 301 to move downward through the connection end 305. Three sets of negative pressure suction cups 301 are installed at the bottom of the delivery pipe 301. 3. The suction cup 303 moves downward synchronously and fits tightly against the surface of the metal roof panel. After the suction cup 303 is in place, the air pump 307 is started. The air inside the suction cup 303 is extracted through the hose 304, connecting pipe 302 and delivery pipe 301, so that a negative pressure environment is formed inside the suction cup 303. Under the action of external atmospheric pressure, the suction cup 303 is firmly adsorbed onto the surface of the metal roof panel, thereby fixing the walking base plate 1 relative to the roof panel and providing stable standing and working support for maintenance personnel.

[0025] Please see Figure 9-12A metal roof anti-slip walking device for easy on-site maintenance, the cleaning component 6 includes a support plate 601, a servo motor 602 installed inside the support plate 601, a balance plate 603 at the output end of the servo motor 602, a drive ring 604 connected to the outside of the balance plate 603, a rotating seat 605 at the bottom end of the drive ring 604, a movable rod 606 connected to the rotating seat 605, a cleaning brush 607 on the outer wall of the movable rod 606, multiple movable rods 606, and the movable rods 606 and the rotating seat 605 are movably connected by a connecting ring, the drive ring 604 and the servo motor 602 are rotatably connected by the balance plate 603, the support plate 601 and the support seat 605 are adjustable and fixed by damping and a rotating shaft, a corresponding battery 4 is installed inside the support plate 601, and the battery 4 inside the support plate 601 is electrically connected to the servo motor 602 by a power line, the balance plate 603 and the servo motor 602 are fixedly connected by a connecting shaft, the movable rod 606... 06. The cleaning brush 607 is made of flexible ABS plastic. Before walking, the maintenance personnel start the power supply of the battery 4 inside the support plate 601. The servo motor 602 is powered on and starts. The output end of the servo motor 602 is fixedly connected to the balance plate 603 through the connecting shaft, driving the balance plate 603 to rotate around its axis. The drive ring 604 rotates synchronously with the balance plate 603. When rotating, the rotating seat 605 and the connecting ring drive multiple movable rods 606 to unfold outward. The outer wall of each movable rod 606 is equipped with a cleaning brush 607. When the drive ring 604 rotates, the rotating seat 605 drives multiple movable rods 606 and cleaning brushes 607 to make circular motion around the axis of the drive ring 604. Each movable rod 606 unfolds outward under the action of centrifugal force, so that the cleaning brush 607 contacts and cleans the roof panel surface in front of the walking base plate 1 with a certain pressure, so as to enhance the friction between the side friction block 203, the end friction block 204 and the roof, thereby improving the stability of the walking device on the roof.

[0026] Working principle: When using this invention, maintenance personnel place their feet between the fixing strap 201 and the tightening strap 202 on the walking base plate 1. The tightening strap 202 secures the feet to the walking base plate 1, ensuring that the walking base plate 1 moves synchronously with the feet. The bottom of the walking base plate 1 is equipped with side friction blocks 203 and end friction blocks 204. The two sets of side friction blocks 203 are located on the left and right sides of the walking base plate 1, respectively, and the end friction blocks 204 are located at the front and rear ends of the walking base plate 1. The three sets of friction blocks are made of rubber and are in direct contact with the metal roof surface. When walking, the weight of the human body compresses the side friction blocks 203 and end friction blocks through the walking base plate 1. 204, after being subjected to force, makes it tightly adhere to the roof surface. The friction between the friction block and the roof panel provides basic anti-slip resistance, preventing maintenance personnel from slipping when walking on the sloping roof. Maintenance personnel issue control commands through the remote control 309 located in the storage box 308 on one side of the walking base plate 1. The remote control 309 is electrically connected to the air pump 307 and cylinder 306 through the PLC controller. After receiving the start signal, the cylinder 306 drives the delivery pipe 301 to move downward through the connection end 305. The three sets of negative pressure suction cups 303 set at the bottom of the delivery pipe 301 move downward synchronously and tightly adhere to the surface of the metal roof panel. After the negative pressure suction cups 303 are in place... When the air pump 307 starts, it extracts air from inside the negative pressure suction cup 303 through the hose 304, connecting pipe 302, and delivery pipe 301, creating a negative pressure environment inside the suction cup 303. Under the action of external atmospheric pressure, the suction cup 303 is firmly adsorbed onto the surface of the metal roof panel, thereby fixing the walking base plate 1 relative to the roof panel and providing stable standing and working support for maintenance personnel. Before the maintenance personnel walk, the battery 4 inside the support plate 601 is activated, energizing and starting the servo motor 602. The output end of the servo motor 602 is fixedly connected to the balance plate 603 through the connecting shaft, driving the balance plate 603 to rotate around its axis. The ring 604 rotates synchronously with the balance plate 603. When rotating, it drives multiple movable rods 606 to unfold outward through the rotating seat 605 and the connecting ring. Each movable rod 606 has a cleaning brush 607 on its outer wall. When the drive ring 604 rotates, the rotating seat 605 drives multiple movable rods 606 and cleaning brushes 607 to make circular motion around the axis of the drive ring 604. Each movable rod 606 unfolds outward under the action of centrifugal force, so that the cleaning brushes 607 contact and clean the roof panel surface in front of the walking base plate 1 with a certain pressure, so as to enhance the friction between the side friction blocks 203, the end friction blocks 204 and the roof, thereby improving the stability of the walking device on the roof.
