Description

Technical Field

[0001] The present application relates to the technical field of climbing equipment, and specifically to a climbing support device with high connection stability. Background Art

[0002] A climbing frame is a device used for aerial work and is widely used in construction, equipment installation, maintenance and overhaul, etc. It is designed to provide workers with a safe and stable aerial operation platform.

The patent is equipped with a supporting plate, rollers, guide rails, a hydraulic press, and support legs. The workbench is raised and lowered by a worm gear screw elevator. The higher the position of a person standing on the workbench, the higher the center of gravity, and the more unstable the climbing frame is.

[0040] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0042] Example 1:

[0043] This embodiment mainly describes the basic structure and working principle of the climbing support device, specifically:

[0044] like Figure 1-Figure 3 As shown, the present application provides a climbing support device with high connection stability, including a climbing mechanism 1, the climbing mechanism 1 including a frame 11, a wheel 12 is installed at the bottom of the frame 11, and a handle 13 is hinged on one side of the frame 11, so that a worker can pull the frame 11 to a work area through the handle 13;

[0045] At the same time, a scissor lifting mechanism is provided on the frame 11, which includes two sets of side frames 14 symmetrically arranged, and the side frames 14 are composed of multiple sets of front rods 141 and rear rods 142 that are hinged to each other along the height direction. Figure 1-Figure 2The side frame 14 is placed in a position such that the left end of the rear rod 142 at the bottom is hinged on the vehicle frame 11, and the right end of the front rod 141 at the bottom is slidably set on the vehicle frame 11. At the same time, a platform 15 is set on the top of the side frame 14, and the left end of the front rod 141 at the top is hinged to the bottom of the platform 15, and the right end of the rear rod 142 at the top is slidably set on the bottom of the platform 15, so that when the right end of the front rod 141 at the bottom slides on the vehicle frame 11, the multiple groups of front rods 141 and rear rods 142 will rotate and move closer to or away from each other, and when they move closer to each other, the platform 15 will rise, and when they move away from each other, the platform 15 will fall.

[0046] In order to drive the movement of the front rod 141 and the rear rod 142, as Figure 2-Figure 3 As shown, two sets of connecting rods 110 at different heights are provided on the inner sides of the two sets of side frames 14. The connecting rods 110 connect the corresponding positions of the two sets of side frames 14 to facilitate synchronous movement. At the same time, a hydraulic cylinder 19 is hingedly connected to the connecting rod 110 at the lower position. The output end of the hydraulic cylinder 19 is hingedly connected to the connecting rod 110 at the higher position. Therefore, when the hydraulic cylinder 19 extends and retracts, it can drive the multiple sets of front rods 141 and rear rods 142 to rotate synchronously, thereby driving the platform 15 to rise or fall.

[0047] At the same time, a hydraulic pump 112 is fixedly mounted on the vehicle frame 11, and a control box 111 is provided on the vehicle frame 11. The control box 111 has buttons, and a PLC control system is provided inside the control box 111. The PLC control system is electrically connected to the hydraulic pump 112, so that the PLC control system can be operated by the buttons to control the hydraulic pump 112 and the hydraulic cylinder 19, thereby controlling the lifting and lowering of the platform 15.

[0048] In order to improve the stability of the platform 15 during operation, Figure 1 As shown, two sets of extension frames 16 are fixedly provided at the bottom of the vehicle frame 11. The extension frames 16 are provided with vertical threaded holes (not shown in the figure). Anchor bolts 17 are threadedly connected to the threaded holes. When the vehicle frame 11 is moved to the designated working position, the anchor bolts 17 are rotated downward so that the bottoms of the anchor bolts 17 abut against the ground, thereby auxiliary fixing the vehicle frame 11 and improving the stability of the vehicle frame 11 during operation.

[0049] At the same time, a fence 18 is provided around the top of the platform 15 to protect the workers during the high-altitude operation to ensure the safety of the operation.

[0050] When the climbing mechanism 1 is used for high-altitude glass installation and maintenance operations, in order to further improve the stability of the climbing mechanism 1, such as Figure 4-Figure 5 and Figure 7As shown, an adsorption mechanism 2 is provided on the fence 18, and the adsorption mechanism 2 is suitable for adsorption with the glass in a vacuum manner to improve the stability of the climbing mechanism 1, specifically:

[0051] The adsorption mechanism 2 includes a panel 21 provided on the fence 18, a cylinder 22 being fixedly mounted on the inner side of the panel 21, an output end of the cylinder 22 passing through the panel 21 and being fixedly mounted with an adsorption rack 23, an end of the adsorption rack 23 away from the cylinder 22 being fixedly mounted with an adsorption plate 24, on which a plurality of adsorption nozzles 25 are evenly arranged;

[0052] It should be noted that a negative pressure pump (not shown in the figure) is provided on the adsorption frame 23, which is connected to the adsorption nozzle 25. When the platform 15 reaches the designated working position, the control cylinder 22 extends, thereby pushing the adsorption plate 24 toward the glass until the adsorption nozzle 25 is in contact with the glass.

[0053] Then the negative pressure pump is started to make the adsorption nozzle 25 have negative pressure, and then adsorb on the surface of the glass, so that the platform 15 can be stabilized in the specified position, further improving the stability of the platform 15 to ensure the safety of high-altitude operations.

[0054] Furthermore, when performing maintenance work on high-altitude glass, sometimes the building has a strange shape and tilted glass will appear. In order to make the applicability of the adsorption mechanism 2 wider, such as Figure 5-Figure 6 As shown, an adjustment mechanism 3 is provided on the fence 18, and the adjustment mechanism 3 includes a fence rod 181 fixedly mounted on the fence 18, a rotating rod 35 is rotatably provided on the fence rod 181, and the enclosure 21 is fixedly mounted on the rotating rod 35, so that the rotating rod 35 can rotate on the fence rod 181 and drive the enclosure 21 to rotate synchronously to adjust the angle of the enclosure 21, and further adjust the adsorption angle of the adsorption nozzle 25, so as to adapt to glass operations at different angles;

[0055] At the same time, a rocking plate 31 is fixedly mounted on the rotating rod 35, and crank handles 32 are evenly arranged along the circumferential direction of the rocking plate 31. The crank handles 32 are suitable for workers to grasp to rotate the rotating rod 35, thereby adjusting the adsorption angle of the adsorption nozzle 25;

[0056] In order to fix the adjusted rocking plate 31, a plug plate 33 is fixedly installed on the surrounding rod 181, and a pin 34 is threaded on the plug plate 33. At the same time, a gap is formed between the evenly arranged rocking handles 32, and the gap cooperates with the pin 34. Therefore, when the rocking plate 31 needs to be fixed in position, it is only necessary to screw the pin 34 into the gap between the rocking handles 32. If the rocking plate 31 needs to be unlocked, the pin 34 can be unscrewed.

[0057] Example 2:

[0058] When the adsorption mechanism 2 is adsorbing the glass, because it is high-altitude glass, the glass will be covered with dust due to not being cleaned for a long time. If adsorption is performed directly, it will not only contaminate the adsorption nozzle 25, but may also cause poor adsorption.

[0059] In order to solve the above problems, Figure 7-Figure 9 As shown, a cleaning mechanism 4 is provided on the outside of the adsorption plate 24. The cleaning mechanism 4 is used to clean the glass before the adsorption nozzle 25 is attached to the glass. The cleaning mechanism 4 includes two groups of cleaning plates 41 provided on the outside of the adsorption plate 24. The cleaning plates 41 are provided with multiple groups of cleaning heads 42 for cleaning the glass. At the same time, two groups of slide grooves 241 are provided on the adsorption plate 24. An extension seat 48 is slidably provided in the slide grooves 241. The extension seat 48 is connected to the cleaning plate 41, so that when the extension seat 48 slides in the slide groove 241, the cleaning plate 41 can be driven to move synchronously.

[0060] It should be noted that an elastic member (not shown in the figure) is provided between the extension seat 48 and the cleaning plate 41. In the initial state, the elastic member causes the cleaning plate 41 to be located outside the adsorption nozzle 25 to protect the adsorption nozzle 25.

[0061] When the cleaning plates 41 are squeezed, they can move closer to the adsorption plate 24 and lower than the adsorption point of the adsorption nozzle 25. In other words, the two sets of cleaning plates 41 are close to each other in the initial state and are located outside the adsorption nozzle 25 to completely cover the adsorption nozzle 25 to protect the adsorption nozzle 25. When the adsorption nozzle 25 needs to be adsorbed, the two sets of cleaning plates 41 move to the sides (the control of movement will be explained below) and expose the adsorption nozzle 25. During the movement of the cleaning plates 41, they will first contact the glass and wipe the area where the adsorption nozzle 25 will be adsorbed.

[0062] When the two sets of cleaning plates 41 move to the side of the suction nozzles 25, the cleaning plates 41 are pressurized by the glass due to the continuous advancement of the cylinders 22. Due to the action of the elastic members, the cleaning plates 41 move closer to the suction plates 24. At this time, because the cleaning plates 41 are located outside the multiple sets of suction nozzles 25, they do not affect the advancement of the suction nozzles 25.

[0063] When the adsorption nozzle 25 needs to be retracted, only the reverse operation is required. In this way, the glass to be adsorbed by the adsorption nozzle 25 can be cleaned while protecting the adsorption nozzle 25, thereby achieving the effect of double protection of the adsorption nozzle 25.

[0064] In order to control the movement of the two sets of cleaning plates 41, continue to refer to Figure 7-Figure 9 A first rack 43 is fixedly mounted on the enclosure 21 and passes through the adsorption rack 23 , so that the adsorption rack 23 does not interfere with the first rack 43 when it moves;

[0065] At the same time, two sets of bearing seats 45 are fixedly mounted on the adsorption frame 23, and a control shaft (not shown in the figure) is mounted between the two sets of bearing seats 45. A first gear 47 is fixedly mounted on the control shaft. The first gear 47 is engaged with the first rack 43, so that when the adsorption frame 23 moves, the first gear 47 is driven to move synchronously. At this time, due to the action of the first rack 43, the first gear 47 is rotated and drives the control shaft to rotate synchronously.

[0066] like Figure 9-10 As shown, a second gear 46 is fixedly installed on both sides of the first gear 47 on the control shaft, and an extension seat 48 passes through the adsorption plate 24 and is fixedly installed with a slide 51. A second rack 54 is fixedly provided on the slide 51. The second rack 54 is engaged with the second gear 46, so that during the rotation of the control shaft, the second gear 46 can be driven to rotate synchronously, and then the extension seat 48 is driven to slide in the slide groove 241 through the second rack 54, thereby achieving the control of the two groups of cleaning plates 41 to move away from and approach each other.

[0067] In order to remove the debris adhering to the cleaning head 42, as Figure 9-10 As shown, a connecting plate 44 is fixedly mounted on the adsorption plate 24, and a connecting disc 52 is fixedly mounted on the connecting plate 44. At the same time, a protruding rod 57 is provided on one side of the slide 51. The protruding rod 57 slides through the connecting disc 52, and a first spring 53 is provided on the outer ring of the protruding rod 57. The first spring 53 is located between the slide 51 and the connecting disc 52.

[0068] At the same time, a mounting groove 511 is formed on the slide 51, and a separation tooth 55 is slidably arranged in the mounting groove 511. A second spring 56 is fixedly installed between the separation tooth 55 and the slide 51. Therefore, in the initial state, due to the action of the second spring 56, a certain distance is maintained between the separation tooth 55 and one end of the second rack 54. The distance is the tooth pitch length of the second rack 54.

[0069] In summary, when the cylinder 22 drives the adsorption rack 23 to approach the glass, the first rack 43 and the first gear 47 drive the control shaft to rotate, and synchronously drive the second gear 46 to rotate;

[0070] When the second gear 46 rotates, it drives the second rack 54 to translate, thereby driving the extension seat 48 to slide in the slide groove 241, thereby achieving the purpose of controlling the two sets of cleaning plates 41 to move away from each other;

[0071] When the cylinder 22 drives the adsorption frame 23 to retract, it drives the two groups of cleaning plates 41 closer to each other. At this time, the second gear 46 will continue to engage with the second rack 54 and engage with the separation tooth 55 in the final position. Due to the action of the second spring 56, the separation tooth 55 will have a short rebound action, thereby causing the slide 51 to vibrate, and then the two groups of cleaning plates 41 that are close to each other will contact and collide and vibrate, so that the debris adhering to the cleaning head 42 can be vibrated and fall off.

[0072] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
