Description

Technical Field

[0001] The utility model relates to the technical field of aerial work, in particular to an anti-collision aerial work device. Background Art

[0002] Aerial work equipment refers to equipment used for working at heights, usually including hanging baskets, lifts, scaffolding, etc. These equipment can help workers safely perform various operations at heights, such as construction, maintenance, cleaning, etc. The use of aerial work equipment can improve work efficiency, reduce safety risks, and protect the lives of workers.

[0003] Aerial work equipment may shake due to its own gravity and wind force when in the air, and then the equipment may be damaged due to collision. Therefore, it is necessary to use an anti-collision aerial work equipment to prevent losses caused by collision. For example, the prior art Chinese patent announcement number "CN108394846A" discloses an anti-collision device for aerial work vehicles, whose structure includes a collision trigger device, a pressure monitoring gauge, a control panel, a moving wheel, a connecting rod, a machine body, a lifting module, and a high-altitude operating table. The collision trigger device is installed inside the machine body, and the connecting rods are parallel to each other and the sides are close to the machine body. The two ends of the bottom of the body are mechanically connected, the two ends of the connecting rod are vertically connected to the inside of the moving wheel, the bottom of the lifting module is vertically connected to the inside of the body, the top of the lifting module is welded to the bottom of the aerial operating table, the back of the control panel is vertically connected to the front side of the body, the back of the pressure monitoring meter is fixedly connected to the front side of the body and is arranged at the upper right corner of the control panel. The present invention provides an anti-collision device for an aerial work vehicle. The device can stop the vehicle body in time when the aerial work vehicle is about to collide. At the same time, the device can also adjust and control the anti-collision distance according to actual conditions, which can improve the convenience of using the aerial work vehicle.

[0004] Some aerial work equipment can only prevent the vehicle body from colliding with objects. However, in actual operations, considering that the operating table carried by the aerial work equipment does not have anti-collision measures to prevent collisions at high altitudes, on the one hand, it is easy for the operating table to collide with objects due to the lack of anti-collision measures, causing damage to the equipment and affecting the normal operation of the equipment. On the other hand, it cannot provide protection for the staff located in the operating table, resulting in limited scope of application of the device. Utility Model Content

[0005] The utility model aims to solve the disadvantage in the prior art that the operating platform has no anti-collision measures to prevent collision in the air, and proposes an anti-collision high-altitude working equipment.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below 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, rather than all of the embodiments.

[0021] Reference Figure 1-5 A collision-proof aerial work equipment comprises a moving seat 1, a workbench 3 is arranged on the top of the moving seat 1 through a lifting mechanism 2, the lifting mechanism 2 is used to adjust the height of the workbench 3, a protective plate 4 is arranged on the side of the workbench 3, and a supporting mechanism 5 and a protective component 6 are arranged between the protective plate 4 and the supporting mechanism 5, the protective plate 4 is used to provide elastic support for the protective plate 4, and the protective component 6 is used to suspend the workbench 3 from continuing to rise and fall.

[0022] It is worth mentioning that, through the elastic support provided by the supporting mechanism 5 for the protective plate 4, the protective plate 4 can well protect the workbench 3, and prevent the workbench 3 from directly colliding with an object and causing damage to the equipment;

[0023] Among them, the advantage of using the protection component 6 to resist the button 65 is that it can prevent the workbench 3 from continuing to rise and fall and causing a collision to occur again. The lifting mechanism 2 can continue to lift the workbench 3 only after separating from the object that caused the collision.

[0024] Specifically, the lifting mechanism 2 includes a set of scissor-type lifting frames 22 driven by a motor 21 . A control unit is disposed in the moving seat 1 , and the control unit is electrically connected to the motor 21 .

[0025] Furthermore, the supporting mechanism 5 includes a guide rod 52 fixedly installed on the side of the workbench 3 through a fixed seat 51, and both ends of the guide rod 52 are slidably connected with a movable seat 53, and a first spring 54 is sleeved on the outer periphery of both ends, and the two ends of the first spring 54 are respectively fixedly connected to the movable seat 53 and the side of the fixed seat 51, and a U-shaped frame 55 is fixedly installed on the side of the protective plate 4, and a pair of relatively arranged support rods 56 are rotatably connected between the U-shaped frame 55 and the opposite side of a pair of movable seats 53.

[0026] It is worth mentioning that the first spring 54 is used for resetting. When the protective plate 4 is collided and squeezed, it will squeeze the pair of support rods 56, and the pair of support rods 56 will drive the movable seat 53 to move. Under the elastic support of the first spring 54, it can play a role of elastic support for the protective plate 4, and can also reset the protective plate 4 after detaching from the collision object.

[0027] Furthermore, a buffer member 7 is provided between the protective plate 4 and the workbench 3. The buffer member 7 includes a buffer cylinder 71 and a piston rod 72 fixedly installed on the side of the protective plate 4 and the workbench 3. A vent hole 73 runs through the bottom of the buffer cylinder 71 and is slidably connected to the piston rod 72. A second spring 74 is fixedly connected between the piston rod 72 and the inner side of the buffer cylinder 71.

[0028] Specifically, the buffer member 7 can be used to buffer and reduce shock on the protective plate 4, and the vent hole 73 can be used to slowly move the piston rod 72 to achieve the purpose of buffering.

[0029] In more detail, the protection component 6 includes a slide groove 61 opened inside the workbench 3, and a locking rod 62 is slidably connected in the slide groove 61. The top of the locking rod 62 is a conical structure, and its bottom passes through the slide groove 61 and is sleeved with a third spring 63. The two ends of the third spring 63 are respectively fixedly connected to the side surface of the top of the locking rod 62 and the inner side surface of the slide groove 61.

[0030] Finally, a push rod 64 is fixedly installed on the side of the protective plate 4, and the other end of the push rod 64 is slidably connected to the slide groove 61 and can slide in contact with the top of the locking rod 62. A button 65 is fixedly installed at the bottom of the workbench 3 below the locking rod 62. The button 65 is electrically connected to the control unit, and the locking rod 62 can contact the button 65.

[0031] Specifically, when the protective plate 4 is squeezed and the push rod 64 is moved, the push rod 64 will slide against the top of the stop rod 62, and the stop rod 62 will move downward under the squeeze and then against the button 65;

[0032] Among them, the button 65 is electrically connected to the control unit. After the button 65 is pressed, an electrical signal is sent to the control unit, and the control unit stops the operation of the motor 21, and the lifting frame 22 stops lifting to prevent the workbench 3 from continuing to collide. After that, after the protective plate 4 is separated from the object, the locking rod 62 moves upward and separates from the button 65, and the control unit drives the motor 21 and the lifting frame 22 again to drive the workbench 3 to continue to lift.

[0033] Working mode: When working, the motor 21 drives the lifting frame 22 to move up and down. When the workbench 3 collides with the object, the protective plate 4 contacts and is squeezed. At this time, the protective plate 4 then drives the support rod 56 to squeeze a pair of movable seats 53 toward both sides. The movable seats 53 gradually stop moving under the elastic support of the first spring 54, so as to prevent the collision with the workbench 3 and cause damage to the equipment.

[0034] Then, when the protective plate 4 is squeezed, the protective plate 4 will also drive the abutment rod 64 to slide against the top of the locking rod 62. At this time, the locking rod 62 moves downward due to the squeezing, so that the bottom of the locking rod 62 abuts against the button 65. At this time, the button 65 sends an electrical signal to the control unit to stop the motor 21 from driving the lifting frame 22, so as to prevent the workbench 3 from colliding again.

[0035] Finally, when the protective plate 4 is separated from the object, the piston rod 72, under the action of the second spring 74, cooperates with the first spring 54 to drive the protective plate 4 back to its original position, the locking rod 62 moves the disengagement button 65 upward, and the control unit drives the motor 21 and the lifting frame 22 again to drive the workbench 3 to continue to rise and fall.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
