However, during the work process, when there is interference from external forces such as wind, the high-altitude workers will swing due to lack of effective fixation, affecting normal work, and even affecting the safety of the workers in serious cases. In addition, the high-altitude workers only rely on the safety rope to exert tension on their bodies during work, and there is no support point for their feet to step on. It is very uncomfortable for the high-altitude workers to work while suspended in the air.

[0003] In summary, there is an urgent need for an aerial work device to solve the problems existing in the prior art. Summary of the invention

[0017] The application of the technical solution of the present invention has the following beneficial effects:

[0018] (1) In the present invention, a pedal assembly and a suction cup assembly are connected through a connecting assembly, and a driving member and a sliding member that cooperate with each other are arranged between the pedal assembly and the connecting assembly. The pedal assembly rotates to drive the driving member to rotate, so that the sliding member slides along the length direction of the connecting frame. A protrusion for pulling up the pull rod is arranged on the sliding member, so that the suction cup assembly can adsorb the glass curtain wall, and the position of the high-altitude workers can be fixed during operation. At the same time, the pedal assembly provides certain support to the workers, thereby improving the comfort of the workers during high-altitude operations.

[0019] (2) In the present invention, the driving member is connected to the pedal body, and the driving member is hinged to the connecting frame. When the pedal body rotates with the operator's feet, it can drive the driving member to rotate, thereby promoting the sliding member to move.

[0020] (3) In the present invention, the driving member is a gear, and the sliding member is provided with a rack that cooperates with the gear, which can convert the rotational movement of the pedal body and the driving member into a linear sliding movement of the sliding member. The contact and compression of the pull rod is achieved through the protrusion of the sliding member, making the adsorption and release of the suction cup assembly simple and easy to operate, and the operator can just step on or lift it up with his feet.

[0021] (4) In the present invention, a recessed positioning portion is provided on the sliding member so that the rolling member passes over the protruding portion and is stuck in the positioning portion, thereby providing the operator with a tactile signal that the suction cup assembly has completed adsorption, and the operator can start working at high altitude.

[0022] (5) In the present invention, the axis of the pull rod is perpendicular to the length direction of the connecting frame, and the pull rod can be pulled up by sliding the sliding member in the vertical direction.

[0023] (6) In the present invention, a safety latch is provided on the pedal body of the pedal assembly, and the safety latch is slidably connected to the pedal body; a pin hole that cooperates with the safety latch is provided on the connecting frame. When the operator senses the tactile signal that the suction cup assembly has completed adsorption, the operator turns the safety latch to insert one end of the safety latch into the pin hole of the connecting frame, thereby fixing the position of the pedal body and the connecting frame, and preventing the sliding of the sliding part due to the operator's mistaken lifting of the foot during work, thereby making the adsorption of the suction cup assembly ineffective.

[0024] (7) In the present invention, an inclined support is provided at the bottom of the pedal body of the pedal assembly, one end of the inclined support is fixedly connected to the pedal body, and the other end of the inclined support is abutted against the connecting frame, so that the pedal body is in a horizontal state, which is convenient for providing fixed support to the operator.

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0035] Embodiment 1:

[0036] See also Figures 1 to 6 , a high-altitude working device, this embodiment is used to fix the position of the operator during high-altitude working.

[0037] A high-altitude working device comprises a pedal assembly 1, a connecting assembly 2 and at least one set of suction cup assemblies 3; Figure 1 , the connecting assembly 2 comprises a connecting frame 2.1, the suction cup assembly 3 is connected to one side of the connecting frame 2.1, and the pedal assembly 1 is hinged to the other side of the connecting frame 2.1;

[0038] The connecting assembly 2 further comprises a sliding member 2.2 arranged on a side of the connecting frame 2.1 close to the pedal assembly 1; the sliding member 2.2 is slidably connected to the connecting frame 2.1; a driving member 1.1 cooperating with the sliding member 2.2 is arranged on a side of the pedal assembly 1 close to the connecting frame 2.1, and the sliding member 2.2 is driven to slide along the length direction of the connecting frame 2.1 by the rotation of the driving member 1.1;

[0039] The suction cup assembly 3 includes a suction cup body 3.1 and a pull rod 3.2 connected to the suction cup body 3.1; the sliding member 2.2 is provided with a protrusion 2.2.1, and the pull rod 3.2 is provided with a rolling member 3.2.1 for contacting the protrusion 2.2.1. The protrusion 2.2.1 squeezes the rolling member 3.2.1 to pull up the pull rod 3.2, so that the suction cup body 3.1 completes the adsorption. Figure 3 As shown, a slope is provided on one side of the protrusion 2.2.1, so that when the sliding member 2.2 slides along the length direction of the connecting frame 2.1 to squeeze the rolling member 3.2.1, the rolling member 3.2.1 rolls along the slope on one side of the protrusion 2.2.1, and the pull rod 3.2 is pulled to the right, so that a vacuum cavity is formed inside the suction cup body 3.1, and the suction cup assembly 3 is adsorbed on the glass curtain wall or wall. The suction cup assembly 3 is designed with reference to the pull-out suction cup in the prior art. In this embodiment, the outer shell of the suction cup assembly 3 is integrated with the connecting frame 2.1.

[0040] In this embodiment, two suction cup assemblies 3 are connected to one side of the connecting frame 2.1 to enhance the adsorption stability of the aerial work device. The sliding member 2.2 is provided with two protrusions 2.2.1 to contact and squeeze the pull rods 3.2 of the two suction cup assemblies 3. Figure 2 shown.

[0041] The rolling element 3.2.1 is a rolling bearing, which can reduce the friction between the sliding element 2.2 and the rolling element 3.2.1.

[0042] The driving member 1.1 is hinged to the connecting frame 2.1, and the driving member 1.1 is fixedly connected to the pedal body 1.2 of the pedal assembly 1. The driving member 1.1 and the pedal body 1.2 rotate together around the hinge point between the driving member 1.1 and the connecting frame 2.1. Figure 2 As shown; the pedal body 1.2 of the pedal assembly 1 is provided with a strap 1.5, which can fix the operator's feet to the pedal body 1.2. When the pedal body 1.2 rotates with the construction worker's feet, it will drive the driving member 1.1 to rotate, and the driving member 1.1 drives the sliding member 2.2 to slide along the length direction of the connecting frame 2.1.

[0043] In this embodiment, Figure 2 As shown, the driving member 1.1 is a gear, and the sliding member 2.2 is provided with a rack that cooperates with the driving member 1.1. Through the rotation of the gear, the sliding member 2.2 with the rack slides in the vertical direction to achieve the adsorption and release of the suction cup assembly 3.

[0044] See also Figure 4 and Figure 5 The sliding member 2.2 is also provided with a recessed positioning portion 2.2.2, so that the rolling member 3.2.1 passes over the protruding portion 2.2.1 and is stuck in the positioning portion 2.2.2, which can convey a tactile signal to the operator that the suction cup assembly 3 has completed the adsorption, and the operator can start the high-altitude operation.

[0045] The protruding portion 2.2.1 protrudes from the positioning portion 2.2.2, and the protruding distance is 1mm to 2mm. When the protruding distance is less than 1mm, the tactile signal of the rolling element 3.2.1 stuck in the positioning portion 2.2.2 is not obvious; when the protruding distance is greater than 2mm, the suction of the suction cup assembly 3 may be affected due to the long retraction distance of the pull rod. When assembling the aerial work device, attention should be paid to the meshing position of the gear and the rack, so that when the rolling element 3.2.1 is stuck in the positioning portion 2.2.2, the pedal body 1.2 is perpendicular to the connecting frame 2.1.

[0046] The axis of the pull rod 3.2 is perpendicular to the length direction of the connecting frame 2.1. The pull rod 3.2 can be pulled up by sliding the sliding member 2.2 in the vertical direction. The pull rod 3.2 moves to the right in the horizontal direction to form a vacuum cavity inside the suction cup body 3.1.

[0047] The pedal body 1.2 of the pedal assembly 1 is provided with a safety pin 1.3, and the safety pin 1.3 is slidably connected to the pedal body 1.2; the connecting frame 2.1 is provided with a pin hole 2.1.1 that cooperates with the safety pin 1.3. Figure 6 As shown, when the operator feels the tactile signal that the suction cup assembly 3 has completed adsorption, he or she pulls the safety pin 1.3 so that one end of the safety pin 1.3 is inserted into the pin hole 2.1.1 of the connecting frame 2.1, thereby fixing the relative position of the pedal body 1.2 and the connecting frame 2.1, thereby preventing the sliding member 2.2 from sliding downward due to the operator's mistaken foot lifting during work, thereby rendering the adsorption of the suction cup assembly 3 ineffective.

[0048] An inclined support 1.4 is provided at the bottom of the pedal body 1.2 of the pedal assembly 1, one end of the inclined support 1.4 is fixedly connected to the pedal body 1.2, and the other end of the inclined support 1.4 rests on the connecting frame 2.1, so that the pedal body 1.2 is in a horizontal state, which is convenient for providing fixed support for the operator.

[0049] The method of using the above-mentioned aerial work device is as follows: the operator fixes the foot to the pedal body 1.2 through the strap 1.5, and after tying the safety rope, the operator is lifted and pulled to the outside of the glass curtain wall for aerial work. After arriving at the work site, the aerial work device fixed on the foot is close to the glass curtain wall, so that the suction cup assembly 3 is close to the glass curtain wall; the operator steps on the foot downward, so that the pedal body 1.2 and the driving member 1.1 rotate clockwise, and the sliding member 2.2 moves upward under the action of the driving member 1.1 through the protrusion 2.2.1 to squeeze the rolling member 3.2.1, pull up the pull rod 3.2 of the suction cup assembly 3, and make the suction cup assembly 3 adsorbed on the glass curtain wall; after the rolling member 3.2.1 is stuck in the positioning part 2.2.2, the operator pulls the safety pin 1.3 and inserts the safety pin 1.3 into the pin hole 2.1.1 of the connecting frame 2.1, so as to fix the position between the pedal body 1.2 and the connecting frame 2.1, and then the aerial work can be started. After completing the aerial work, the safety latch 1.3 is pushed to release the pedal body 1.2 and the connecting frame 2.1. The operator lifts his foot to make the pedal body 1.2 and the driving member 1.1 rotate counterclockwise. The sliding member 2.2 moves downward under the action of the driving member 1.1, so that the pull rod 3.2 retracts into the suction cup assembly 3, and the suction cup assembly 3 is released, so that the operator's working position can be moved.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
