Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0025] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0026] Reference Figure 1-7 As shown, a preferred embodiment of the present invention is provided.

[0027] The high-altitude trackless mobile working platform is used for high-altitude operations such as exterior wall construction, curtain wall installation, insulation construction, and maintenance and cleaning of exterior walls of high-rise buildings. The use of this type of aerial work equipment can avoid the need for scaffolding. It is flexible to operate, easy to move, convenient and practical, safe and reliable, occupies a small area, has low requirements for the use environment, and can be operated during the day.

[0028] The high-altitude trackless mobile working hanging basket in the present invention includes an operating mechanism and a suspension platform 22. The operating mechanism drives the suspension platform 22 to move up and down to realize high-altitude working. When using the suspension platform 22 for working, obstacles that affect the normal operation of the suspension platform 22 should be eliminated. In the range below the suspension platform 22 that may cause falling objects to cause injuries, a safety isolation area and warning signs are set up, and personnel and vehicles are not allowed to stay or pass.

[0029] The operating mechanism includes a movable chassis 10, multiple first wire-releasing mechanisms 12, multiple second wire-releasing mechanisms 13, an anti-fall device, a control box 14, and a distribution box 21; the bottom of the movable chassis 10 has multiple rollers, and the entire aerial working equipment can be moved by the rollers, which is convenient for movement and adjustment of the position of the operating mechanism, ensuring that the operating mechanism is moved to a position that is convenient for operation, and there is no need to reinstall various components again.

[0030] The first wire-releasing mechanism 12 and the second wire-releasing mechanism 13 are both arranged on the movable chassis 10. The operating mechanism in the present invention is provided with two first wire-releasing mechanisms 12 and two second wire-releasing mechanisms 13, which are respectively arranged on the left and right sides of the movable chassis 10. The first wire-releasing mechanism 12 and the second wire-releasing mechanism 13 both have winding posts, wherein the winding post 120 of the first wire-releasing mechanism 12 is wound with a first steel wire rope 15, and the winding post 131 of the second wire-releasing mechanism 13 is wound with a second steel wire rope 16, and the diameters of the first steel wire rope 15 and the second steel wire rope 16 are 8 mm or 10 mm; a frame 11 is also provided on the movable chassis 10, and both sides of the suspension platform 22 are connected with the first steel wire rope 15 and the second steel wire rope 1 6. One end of the first steel wire rope 15 is fixed to the suspension platform 22, and then extends through the frame 11 to the first wire-paying mechanism 12 and is wound around the winding post 120; one end of the second steel wire rope 16 is fixed to the suspension platform 22, and then extends through the frame 11 to the winding post 131 of the second wire-paying mechanism 13 and is wound around; the first wire-paying mechanism 12 includes a lift 121 and a motor, and the lift 121 drives the winding post 120 to rotate through the motor 122 to realize the up and down movement of the suspension platform 22, and the second wire-paying mechanism 13 includes a motor 131, and the motor 131 drives the winding post 130 to rotate, drives the second steel wire rope 16 to move up and down, and drives the movement of the suspension platform 22 together with the first steel wire rope 15. The dual control makes the suspension platform 22 run more smoothly.

[0031] In addition, a lighting lamp 30 is provided on the frame 11, and the lighting lamp 30 is electrically connected to a button for controlling the switch of the lighting lamp 30. The button is installed on the frame 11, and the switch is electrically connected to the control box 14. The lighting lamp 30 helps the staff to work at night or in dark weather to ensure the normal progress of the work.

[0032] The anti-fall device includes a safety rope brake 18 and a limit switch 24. The safety rope brake 18 is fixed on both sides of the frame 11. The second wire rope 16 is connected to the winding column 131 of the second wire-releasing mechanism 13, the safety rope brake 18, and the suspension platform 22 in sequence. The winding column 131 is driven to rotate by the motor 130 to control the retraction and release of the second wire rope 16, and cooperates with the first wire rope 15 to realize the up and down movement of the suspension platform; in addition, there are speed sensors on both the first wire-releasing mechanism 12 and the second wire-releasing mechanism 13. 25 is used to detect the wire-releasing speeds of the first wire-releasing mechanism 12 and the second wire-releasing mechanism 13. When the suspension platform 22 is moved up or down, when the speed sensor 25 detects that the wire-releasing speed of the first wire-releasing mechanism 12 does not match the wire-releasing speed of the second wire-releasing mechanism 13, the control box 14 controls the safety rope brake 18 to lock the second steel wire rope 16, so that the suspension platform 22 stops moving up or down, avoiding excessive inclination angles on both sides of the suspension platform 22, thereby ensuring the safety of the staff on the suspension platform 22.

[0033] In addition, before moving the suspension platform 22 upward, the installation position of the limit switch 24 needs to be set according to the upward height of the suspension platform 22. When the limit switch 24 is triggered, the control box 14 controls the first wire-releasing mechanism 12 and the second wire-releasing mechanism 13 to stop releasing the wire, so that the suspension platform 22 is placed at the set height.

[0034] Correspondingly, the high-altitude trackless mobile working hanging basket includes a safety rope 28 and a safety rope collecting machine 29. The safety rope collecting machine 29 is installed on the frame 11 and is used to collect and release the safety rope 28. The upper end of the safety rope 28 is fixed on a reliable position of the building. The safety rope 28 is in a parallel hanging state with the first steel wire rope 15 and the second steel wire rope 16. Safety locks 220 are provided at both ends of the suspension platform 22, and the safety rope 28 is connected to the safety locks 220. During use, it must be ensured that the safety rope 28 is not entangled with the first steel wire rope 15 and the second steel wire rope 16, and the safety rope must not be loose, broken or knotted, so as to ensure the smooth movement of the suspension platform 22 and the safety of the staff.

[0035] When the suspension platform 22 is on the ground, the lock core of the safety lock 220 is in a closed state. In the closed state, the lock core of the safety lock 220 automatically blocks the safety rope 28, and the safety rope 28 cannot slide up and down at this time. In this way, if the first steel wire rope 15 or the second steel wire rope 16 breaks or the first wire-releasing mechanism 12 or the second wire-releasing mechanism 13 has problems causing the suspension platform 22 to fall rapidly, the safety lock 220 can quickly lock the safety rope 28, thereby preventing the suspension platform 22 from continuing to fall; when the suspension platform 22 is driven to rise, the safety rope 28, due to the action of gravity, causes the pulley fulcrum of the safety lock 220 supported on the safety rope 28 to support the firmware connecting the lock core, so that it changes from a closed state to an open state, so that the fixing force acting on the safety rope 28 disappears, and the resistance to the rise and fall of the suspension platform 22 disappears, allowing the suspension platform 22 to move smoothly.

[0036] The above-mentioned high-altitude trackless mobile working hanging basket can directly move the aerial working equipment to the construction site when it is needed, without the need to perform preparatory work such as the installation of the suspension platform 22, the counterweight structure 17 and the wire rope again. The aerial working mechanism of the present invention, when in use, realizes the up and down movement of the suspension platform 22 through the first wire-releasing mechanism 12 and the second wire-releasing mechanism 13, and detects the retracting and releasing speeds of the first wire-releasing mechanism 12 and the second wire-releasing mechanism 13 through the speed sensor 25. When the speed sensor 25 detects that the retracting and releasing speeds of the first wire-releasing mechanism 12 and the second wire-releasing mechanism 13 are inconsistent, the control box 14 will promptly control the safety rope brake 18 to lock the second wire rope 16, and promptly avoid the tilting of the suspension platform 22 to ensure the safety of the staff; the present invention controls the up and down movement of the suspension platform 22 through a dual control mechanism, and promptly stops it when the suspension platform 22 tilts, fully ensuring the safety of the staff, and because the dual control mechanism is used to lower the suspension platform, the stable movement of the suspension platform 22 can be ensured, further ensuring the safety of the staff, and the operation is convenient.

[0037] The weight of the counterweight structure 17 is much greater than the weight of the suspension platform 22, and the counterweight structure 17 is detachably connected to the movable chassis 10; the counterweight structure 17 includes a plurality of counterweight blocks, which are stacked and arranged for easy disassembly and transportation.

[0038] The counterweight structure 17 is provided with a steering wheel 33 and a motor 34. The bottom of the counterweight structure 17 has wheels. The counterweight structure 17 is connected to the movable chassis 10. Then the user can start the motor 34, and the motor 34 drives the wheels to roll, so that the counterweight structure 17 drives the movable chassis 10 to move, and the operator can control the direction through the steering wheel 33, thereby realizing the electric travel of the high-altitude trackless mobile working basket, which can effectively reduce the work pressure of the construction workers.

[0039] A plurality of support frames 31 are provided on the counterweight structure, and the plurality of support frames 31 extend upward. The high-altitude trackless mobile working hanging basket in the present invention comprises a solar panel 32 and a battery 35. The solar panel 32 is mounted on the support frame 31, and the plurality of support frames 31 are arranged at intervals along the length direction of the T-shaped frame, and the heights of the plurality of support frames 31 gradually increase from one end of the T-shaped frame to the other end. The solar panel 32 generates electricity, and the battery 35 is used to store electricity and stabilize the voltage to ensure continuous power supply for the first wire-releasing mechanism 12, the second wire-releasing mechanism 13, and the motor 34. The electricity can be supplied nearby, which is convenient to operate and does not require long-distance transmission, thus avoiding the loss of electric energy caused by long-distance transmission lines. The plurality of counterweight blocks and the solar panel 32 can act as counterweights together.

[0040] In the present invention, the frame body 11 has a T-shaped frame rod, and the two ends of the T-shaped frame rod respectively have a plurality of connecting structures 19, and the connecting structure 19 is used to connect the first steel wire rope 15 and the second steel wire rope 16. The connecting structure 19 includes a fixed part fixed to the T-shaped frame rod and a movable roller 190, and the movable roller 190 is movably connected to the fixed part, and the outer surface of the movable roller 190 is concave to form a positioning groove 191, and the first steel wire rope 15 and the second steel wire rope 16 are embedded in the positioning groove 191. When the first steel wire rope 15 and the second steel wire rope 16 are placed When the wire mechanism 12 and the second wire-releasing mechanism 13 drive the first steel wire rope 15 and the second steel wire rope 16 to move, the movable roller 190 is driven to rotate, and the first steel wire rope 15 and the second steel wire rope 16 are always in the positioning groove 191, avoiding the displacement of the first steel wire rope 15 and the second steel wire rope 16, so that the suspension platform 22 moves smoothly; when the limit switch 24 passes through the connecting structure 19, the limit switch 24 is triggered, and the control box 14 controls the safety rope brake 18 to limit the movement of the second steel wire rope 16.

[0041] In this embodiment, the first steel wire rope 15 is connected to the connection structure 19 located on the inner side of the T-shaped frame rod, and the second steel wire rope 16 is connected to the connection structure 19 located on the outer side of the T-shaped frame rod. This can avoid the first steel wire rope 15 and the second steel wire rope 16 from crossing each other, avoid affecting the normal operation of the aerial work equipment, and also facilitate the connection of the second steel wire rope 16 with the safety rope brake 18.

[0042] Furthermore, a reducer 23 is provided on the movable chassis 10, and the reducer 23 is located between the second wire-releasing mechanism 13 and the safety rope brake 18. The second steel wire rope 16 is connected to the reducer 23, and the second steel wire rope 16 is reduced in speed by the reducer 23. Correspondingly, it is necessary to ensure that the downward or upward movement speed of the second steel wire rope 16 after passing through the reducer 23 is equal to the upward or downward movement speed of the first steel wire rope 15. The reducer 23 includes a shell, and a reduction gear group is provided in the shell. The reduction gear group includes a main gear 230 and a sub-gear 231. The main gear 230 and the sub-gear 231 respectively have columns for winding the second steel wire rope 16, and the main gear 230 and the sub-gear 231 respectively drive the corresponding columns to rotate; the columns are respectively provided with winding grooves 234, and the second steel wire rope 16 is sequentially wound around the columns on the main gear 230 and the columns on the sub-gear 231. Since the main gear 230 is smaller than the sub-gear 231, the deceleration effect is achieved.

[0043] The width of the winding groove 234 on the column on the sub-gear 231 is smaller than the size of two second steel wire ropes 16 but larger than the size of one second steel wire rope 16, ensuring that the second steel wire rope 16 is always embedded in the winding groove 234 during the upward or downward movement, thereby ensuring the smooth movement of the second steel wire rope 16.

[0044] If the first wire-releasing mechanism 12 fails, the speed sensor 25 detects that the wire-releasing speeds of the first wire-releasing mechanism 12 and the second wire-releasing mechanism 13 are inconsistent, and the control box 14 controls the safety rope brake 18 to lock the second steel wire rope 16, thereby preventing the suspension platform 22 from moving downward; if the second wire-releasing mechanism 13 fails, the control box 14 also controls the safety rope brake 18 to lock the second steel wire rope 16, but under the action of the reducer 23, the downward movement speed of the second steel wire rope 16 can be limited to a certain extent, so that the safety rope brake 18 can lock the second steel wire rope 16 in time, thereby ensuring the balance of the suspension platform 22.

[0045] Furthermore, the high-altitude trackless mobile working hanging basket includes a remote controller 27 and a remote controller receiver 26. The remote controller receiver 26 is wirelessly connected to the remote controller 27, and the control box 14 is electrically connected to the remote controller receiver 26. During operation, the staff can adjust the balance of the suspension platform 22 on site through the remote controller 27, or adjust the suspension platform 22 on the suspension platform 22, which is easy to operate. After the staff sends an instruction to move the suspension platform 22 through the remote controller 27, the remote controller receiver 26 receives the signal and transmits the message to the control box 14, and the control box 14 controls the first wire-releasing mechanism 12 or the second wire-releasing mechanism 13 to drive the winding column to operate, thereby realizing the adjustment of the suspension platform 22, which is both convenient and safe.

[0046] Furthermore, the bottom of the movable chassis 10 is movably connected with a positioning structure, which is convenient for positioning the operating mechanism when the suspension platform 22 is below. When the operating mechanism is moved to the specified position, the positioning structure can be used to position the operating mechanism, ensuring that the operating mechanism is always positioned at the specified position during the movement of the suspension platform 22, thereby ensuring the safety of the personnel in the suspension platform 22.

[0047] The positioning structure includes a first support plate 200 and a second support plate 201. One side of the first support plate 200 is hinged to the bottom of the movable chassis 10, and the other side of the first support plate 200 extends in a direction away from the side of the first support plate 200; one end of the second support plate 201 is fixed to the first support plate 200, and the other end of the second support plate 201 extends toward the direction of the roller to form an abutment block 202; when the aerial work equipment is moved to the set position, the positioning structure is moved toward the direction of the roller so that the abutment block 202 is 2 abuts against the roller, at this time, the other side of the first support plate 200 abuts against the ground, thereby positioning the movable chassis 10 and limiting the movement of the movable chassis 10; in this embodiment, positioning structures are respectively provided at the measuring ends of the movable chassis 10, and the abutting blocks 202 on the positioning structures at both ends are respectively oriented toward the middle of the movable chassis 10. When the abutting blocks 202 on the positioning structures at both ends abut against the corresponding rollers, the position of the movable chassis 10 is fixed, thereby ensuring that the suspension platform 22 can move smoothly.

[0048] In addition, the first support plate 200 is retractable, including a first retractable section and a second retractable section. The first retractable section is hinged to the movable chassis 10, and a mounting groove is formed by a depression on the first retractable section. A movable protrusion 203 is provided in the mounting groove, and the movable protrusion 203 is fixed to the groove surface of the mounting groove by a spring. The second retractable section is sleeved on the first retractable section, and the second retractable section has an embedding hole 205 corresponding to the movable protrusion 203. When in use, the second retractable section is moved downward to disengage the movable protrusion 203 from the embedding hole 205, so that the end of the second retractable section abuts the ground. When the positioning structure needs to be folded up, the abutting block 202 is first disengaged from the roller, and then the second retractable section is moved upward, so that the positioning structure can be smoothly folded in a direction away from the roller.

[0049] Furthermore, the abutment block 202 is bent in an arc shape toward the roller, and the middle of the abutment block 202 is recessed into a positioning groove, and the roller is embedded in the positioning groove. The abutment block 202 restricts the roller in the positioning groove to restrict the movement of the roller.

[0050] An elastic member 204 is provided at the bottom of the movable chassis 10, and the end of the elastic member 204 is fixed to the other side of the first support plate 200; when the other side of the first support plate 200 abuts against the ground, the elastic member 204 is stretched. At this time, the elastic member 204 exerts a stretching force on the positioning structure in the direction of the roller, so that the abutting member abuts against the roller more tightly and the positioning effect is better.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
