[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1:

[0028] Please refer to Figure 1 - Figure 7 , an adjustable-height hanging plate and its support, including a support base plate 1, a plurality of rollers 2 are fixedly connected to the bottom of the support base plate 1, a fixing mechanism is provided on the top of the support base plate 1, a support rod 8 is fixedly connected to the top of the support base plate 1, an electric telescopic rod 9 is fixedly connected to one end of the support rod 8, a fixed frame 10 is fixedly connected to one end of the electric telescopic rod 9, a rotation speed sensor 13 is fixedly connected to the inner wall of the fixed frame 10, a second motor 11 is fixedly connected to the side wall of the fixed frame 10, a transmission shaft 12 is fixedly connected to the output end of the second motor 11, a wire winding roller 14 is fixedly connected to the side wall of the transmission shaft 12, a plurality of limit grooves 15 are formed inside the wire winding roller 14, a third electric push rod 37 is fixedly connected to the inner wall of the fixed frame 10, the side wall of the third electric push rod 37 is movably connected to the inner wall of the limit groove 15, a first steel wire rope 16 is fixedly connected to the bottom of the wire winding roller 14, the first steel wire rope 16 is fixedly connected to a second steel wire rope 22 through a clamping mechanism, a hanging plate seat 23 is fixedly connected to the bottom of the second steel wire rope 22, a shock absorption mechanism is fixedly connected to the bottom of the hanging plate seat 23, a first motor 5 is fixedly connected to the top of the support base plate 1, a first electric push rod 6 is fixedly connected to the output end of the first motor 5, an electric clamping plate 7 is fixedly connected to one end of the first electric push rod 6, and the inner wall of the electric clamping plate 7 is movably connected to the side wall of the first steel wire rope 16.

[0029] It should be noted that when the staff move the equipment to the place where work is needed, the arrangement of multiple rollers 2 facilitates the staff to move the equipment. The electric telescopic pipe 4 is started, and the electric telescopic pipe 4 extends above the ground. The first high-pressure air pump 3 is started, and the first high-pressure air pump 3 pumps out all the air between the electric telescopic pipe 4 and the ground through the electric telescopic pipe 4, and uses air pressure to fix the equipment on the ground to prevent the equipment from tipping over when the staff work on the hanging plate seat 23;

[0030] After the equipment is fixed on the ground, after the staff sit on the hanging plate seat 23, the second motor 11 is started, and the second motor 11 drives the transmission shaft 12 to rotate. When the transmission shaft 12 rotates, it drives the wire winding roller 14 to rotate. The wire winding roller 14 drives the hanging plate seat 23 to press down through the first steel wire rope 16, the connecting block 18, the clamping plate 20, the second electric push rod 19, the clamping bin 21 and the second steel wire rope 22 to move the staff to the place where work is needed. The rotation speed of the transmission shaft 12 is monitored in real time through the setting of the rotation speed sensor 13. When the second motor 11 is damaged, the transmission shaft 12 rotates at a high speed under the influence of gravity. The rotation speed sensor 13 detects that the rotation speed of the transmission shaft 12 is abnormal, and the rotation speed sensor 13 controls the third electric push rod 37 to start. The third electric push rod 37 extends into the limiting groove 15 to lock the wire winding roller 14, preventing the transmission shaft 12 from continuously driving the wire winding roller 14 to rotate and causing the hanging plate seat 23 to drop rapidly. The rotation speed sensor 13 controls the first electric push rod 6 to start. The first electric push rod 6 drives the electric clamping plate 7 to move to the side wall of the first steel wire rope 16. The electric clamping plate 7 is started, and the electric clamping plate 7 clamps and fixes the first steel wire rope 16. The first motor 5 is started, and the first motor 5 drives the first electric push rod 6 to rotate. When the first electric push rod 6 rotates, it drives the electric clamping plate 7 to rotate. When the electric clamping plate 7 rotates, it winds the first steel wire rope 16 around the side wall of the first electric push rod 6. When the first steel wire rope 16 is wound, it drives the hanging plate seat 23 to rise through the connecting block 18, the second electric push rod 19, the clamping plate 20, the clamping bin 21 and the second steel wire rope 22 to pull the staff back to the ground, preventing the staff from being suspended in the air for a long time and having an accident;

[0031] When the first steel wire rope 16 breaks during the work of the staff, the second electric push rod 19 is started, and the second electric push rod 19 drives the clamping plate 20 to contract to stop limiting the connecting block 18, so that the clamping bin 21 is separated from the first steel wire rope 16, preventing the staff from falling from inside the hanging plate seat 23 only when one side of the first steel wire rope 16 breaks. The air flow velocity is monitored through the setting of the wind speed detector 31. When the hanging plate seat 23 is separated from the fixation of the first steel wire rope 16, the hanging plate seat 23 drops rapidly under the action of gravity. The wind speed detector 31 monitors that the air flow velocity increases, and controls the parachute pack 30 to start. The parachute inside the parachute pack 30 ejects to reduce the falling speed of the hanging plate seat 23, preventing the hanging plate seat 23 from falling directly and causing the death of the staff;

[0032] When the hanging plate seat 23 slowly drifts in the air, the distance between the protection plate 36 and the ground is monitored in real time through the setting of the infrared rangefinder 38. When the distance between the protection plate 36 and the ground is less than ten meters, the infrared rangefinder 38 controls the electromagnet 35 to turn off, and the electromagnet 35 stops fixing the protection plate 36 to prevent the protection plate 36 from blocking the ejection of the airbag 34. At the same time, the infrared rangefinder 38 controls the second high-pressure air pump 32 to start, and the second high-pressure air pump 32 injects air into the airbag 34 through the air delivery pipe 33, so that the airbag 34 expands out of the protection bin 29 to protect the hanging plate seat 23, avoiding the protection bin 29 directly falling on the ground and causing injuries to the staff. At the same time, it avoids the premature ejection of the airbag 34 from affecting the floating balance of the hanging plate seat 23 in the air.

[0033] In an alternative embodiment: The shock absorption mechanism includes a protection bin 29, the top of the protection bin 29 is fixedly connected to the bottom of the hanging plate seat 23, the inner wall of the protection bin 29 is fixedly connected with a second high-pressure air pump 32, the bottom of the second high-pressure air pump 32 is communicated with an air delivery pipe 33, the bottom of the air delivery pipe 33 is communicated with an airbag 34, the side wall of the airbag 34 is movably connected with the inner wall of the protection bin 29, the bottom of the protection bin 29 is fixedly connected with an electromagnet 35, the bottom of the electromagnet 35 is movably connected with a protection plate 36, and the bottom of the protection plate 36 is fixedly connected with an infrared rangefinder 38.

[0034] It should be noted that when the hanging plate seat 23 slowly drifts in the air, the distance between the protection plate 36 and the ground is monitored in real time through the setting of the infrared rangefinder 38. When the distance between the protection plate 36 and the ground is less than ten meters, the infrared rangefinder 38 controls the electromagnet 35 to turn off, and the electromagnet 35 stops fixing the protection plate 36 to prevent the protection plate 36 from blocking the ejection of the airbag 34. At the same time, the infrared rangefinder 38 controls the second high-pressure air pump 32 to start, and the second high-pressure air pump 32 injects air into the airbag 34 through the air delivery pipe 33, so that the airbag 34 expands out of the protection bin 29 to protect the hanging plate seat 23, avoiding the protection bin 29 directly falling on the ground and causing injuries to the staff. At the same time, it avoids the premature ejection of the airbag 34 from affecting the floating balance of the hanging plate seat 23 in the air.

[0035] In an alternative embodiment: The fixing mechanism includes a first high-pressure air pump 3, the bottom of the first high-pressure air pump 3 is fixedly connected to the top of the support base plate 1, and the bottom of the first high-pressure air pump 3 is communicated with an electric telescopic tube 4.

[0036] It should be noted that the equipment is fixed to the ground through the cooperation of the first high-pressure air pump 3 and the electric telescopic tube 4 to prevent the equipment from tipping over when the staff is working.

[0037] In an alternative embodiment: The clamping mechanism includes a connecting block 18. The bottom of the first steel cable 16 is fixedly connected to the top of the connecting block 18. The side wall of the first steel cable 16 is movably connected to a clamping plate 20. One side of the clamping plate 20 is fixedly connected to a second electric push rod 19. One end of the second electric push rod 19 is fixedly connected to a clamping bin 21. The bottom of the clamping bin 21 is fixedly connected to the top of the second steel cable 22.

[0038] It should be noted that through the cooperation of the first steel cable 16, the connecting block 18, the second electric push rod 19, the clamping plate 20 and the clamping bin 21, the clamping and separation between the first steel cable 16 and the second steel cable 22 can be automatically controlled.

[0039] In an alternative embodiment: A parachute pack 30 is fixedly connected to the side wall of the hanging plate seat 23. A wind speed detector 31 is fixedly connected to the side wall of the hanging plate seat 23.

[0040] It should be noted that during the work of the staff, when the first steel cable 16 breaks, the wind speed detector 31 is provided to monitor the air flow rate. When the hanging plate seat 23 is detached from the fixation of the first steel cable 16, the hanging plate seat 23 drops rapidly under the action of gravity. The wind speed detector 31 detects that the air flow rate increases, and controls the parachute pack 30 to start. The parachute inside the parachute pack 30 ejects to reduce the falling speed of the hanging plate seat 23, and avoid the death of the staff caused by the direct fall of the hanging plate seat 23.

[0041] In an alternative embodiment: A soft sleeve 17 is fixedly connected to the side wall of the first steel cable 16. A cushion 24 is fixedly connected to the inner wall of the hanging plate seat 23.

[0042] It should be noted that through the settings of the soft sleeve 17 and the cushion 24, it is more convenient for the staff to sit inside the hanging plate seat 23.

[0043] In an alternative embodiment: An electric slide rail 25 is fixedly connected to the inner wall of the hanging plate seat 23. The electric slide rail 25 is slidably connected to a storage box 26 through an electronic slider. The side wall of the storage box 26 is slidably connected to the inner wall of the hanging plate seat 23. One side of the storage box 26 is fixedly connected to a handle 28.

[0044] It should be noted that through the cooperation of the storage box 26 and the handle 28, the tools required by the staff can be placed inside the storage box 26.

[0045] In an alternative embodiment: A plurality of partition plates 27 are fixedly connected to the inner wall of the storage box 26. The plurality of partition plates 27 are arranged at equal intervals.

[0046] It should be noted that through the setting of the plurality of partition plates 27, different tools can be separated and stored.

[0047] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0048] During operation, when the staff moves the equipment to the place where work is needed, the arrangement of multiple rollers 2 facilitates the staff to move the equipment. Start the electric telescopic tube 4, and the electric telescopic tube 4 extends above the ground. Start the first high-pressure air pump 3. The first high-pressure air pump 3 extracts all the air between the electric telescopic tube 4 and the ground through the electric telescopic tube 4, and uses air pressure to fix the equipment on the ground to prevent the equipment from tipping over when the staff is working on the hanging plate seat 23.

[0049] After the equipment is fixed on the ground, after the staff sits on the hanging plate seat 23, start the second motor 11. The second motor 11 drives the transmission shaft 12 to rotate. When the transmission shaft 12 rotates, it drives the wire winding roller 14 to rotate. The wire winding roller 14 drives the hanging plate seat 23 to press down through the first steel wire rope 16, the connecting block 18, the clamping plate 20, the second electric push rod 19, the clamping bin 21 and the second steel wire rope 22 to move the staff to the place where work is needed. The rotation speed of the transmission shaft 12 is monitored in real time through the setting of the rotation speed sensor 13. When the second motor 11 is damaged, the transmission shaft 12 rotates at a high speed under the influence of gravity. The rotation speed sensor 13 detects that the rotation speed of the transmission shaft 12 is abnormal. The rotation speed sensor 13 controls the third electric push rod 37 to start. The third electric push rod 37 extends into the limiting groove 15 to lock the wire winding roller 14, preventing the transmission shaft 12 from continuously driving the wire winding roller 14 to rotate and causing the hanging plate seat 23 to drop rapidly. The rotation speed sensor 13 controls the first electric push rod 6 to start. The first electric push rod 6 drives the electric clamping plate 7 to move to the side wall of the first steel wire rope 16. Start the electric clamping plate 7. The electric clamping plate 7 clamps and fixes the first steel wire rope 16. Start the first motor 5. The first motor 5 drives the first electric push rod 6 to rotate. When the first electric push rod 6 rotates, it drives the electric clamping plate 7 to rotate. When the electric clamping plate 7 rotates, it winds the first steel wire rope 16 around the side wall of the first electric push rod 6. When the first steel wire rope 16 is wound, it drives the hanging plate seat 23 to rise through the connecting block 18, the second electric push rod 19, the clamping plate 20, the clamping bin 21 and the second steel wire rope 22 to pull the staff back to the ground, preventing the staff from having an accident when hanging in the air for a long time.

[0050] When the first steel rope 16 breaks during the work of the staff, the second electric push rod 19 is activated. The second electric push rod 19 drives the clamping plate 20 to contract and stop limiting the connecting block 18, so that the clamping bin 21 disengages from the first steel rope 16. This prevents the staff from falling from inside the hanging plate seat 23 in case only one side of the first steel rope 16 breaks. Through the setting of the wind speed detector 31, the air flow rate is monitored. When the hanging plate seat 23 is detached from the fixation of the first steel rope 16, the hanging plate seat 23 rapidly descends under the action of gravity. The wind speed detector 31 detects an increase in the air flow rate and controls the parachute pack 30 to activate. The parachute inside the parachute pack 30 ejects to reduce the falling speed of the hanging plate seat 23 and prevent the hanging plate seat 23 from falling directly and causing the death of the staff.

[0051] When the hanging plate seat 23 slowly drifts in the air, the distance between the protection plate 36 and the ground is monitored in real time through the setting of the infrared rangefinder 38. When the distance between the protection plate 36 and the ground is less than ten meters, the infrared rangefinder 38 controls the electromagnet 35 to turn off, and the electromagnet 35 stops fixing the protection plate 36, preventing the protection plate 36 from blocking the ejection of the airbag 34. At the same time, the infrared rangefinder 38 controls the second high-pressure air pump 32 to start. The second high-pressure air pump 32 injects air into the airbag 34 through the air delivery pipe 33, causing the airbag 34 to expand inside the protection bin 29 to protect the hanging plate seat 23, preventing the protection bin 29 from falling directly onto the ground and injuring the staff, and also preventing the premature ejection of the airbag 34 from affecting the floating balance of the hanging plate seat 23 in the air.
