Technical Field
[0001] This application belongs to the technical field of aerial work equipment, specifically relating to a collision-avoidance aerial work equipment. Background Technology
[0002] There are blind spots in the field of vision of aerial work equipment during movement or operation. If the operator does not operate it properly, the aerial work equipment may collide with the surrounding obstacles, endangering the safety of the operator and the surrounding staff, and causing huge economic losses.
[0003] Most existing anti-collision devices for aerial work platforms are mechanical anti-collision devices triggered by contact switches. They can only provide warnings or limit movement when the contact switch comes into contact with an obstacle. This can easily damage the anti-collision devices or even cause collision accidents, resulting in low safety of aerial work platforms during operation. Utility Model Content

[0008] The control module includes a controller and start / stop switches for controlling the start and stop of chassis sensors and lifting sensors respectively. The controller is communicatively connected to the chassis sensors, lifting sensors, and start / stop switches respectively. The controller is used to control the start / stop switches to open the corresponding sensors according to the working conditions of the aerial work platform.
[0009] In this embodiment, the chassis sensor includes a front sensor and a rear sensor. The front sensor is located on the front side of the chassis device and is used to detect obstacles on the front side. The rear sensor is located on the rear side of the chassis device and is used to detect obstacles on the rear side. The front sensor, the rear sensor and the lifting sensor are each equipped with a start / stop switch.
[0010] In this embodiment, the lifting platform includes a scissor lift mechanism and a working platform. The scissor lift mechanism is mounted on the chassis device, and the working platform is located at the end of the scissor lift mechanism away from the chassis device. The scissor lift mechanism is capable of lifting or lowering the working platform. A first protective housing is provided in the gap between the chassis device and the scissor lift mechanism, and the inner cavity of the first protective housing can accommodate the front sensor.
[0011] In this embodiment of the application, the top wall of the first protective housing is provided with a clearance slope, which is inclined downward in the direction from front to back.
[0012] In this embodiment of the application, the rear side of the chassis device has at least two spaced-apart walking steps, one of which has a second protective housing at its bottom, and the inner cavity of the second protective housing can accommodate the rear sensor.
[0013] In this embodiment, the lifting sensor includes a sensor body and a third protective housing. The third protective housing is disposed on the lifting platform and includes a mounting section and a signal transmitting section arranged sequentially. The sensor body is placed on the mounting section and the signal transmitting head is arranged facing the signal transmitting section. The top wall of the signal transmitting section has a transmitting port. The signal transmitting section has a signal reflector on the side facing the signal transmitting head. The signal reflector is inclined away from the sensor body in the direction from bottom to top.
[0014] In this embodiment, the anti-collision aerial work equipment also includes a mounting bracket, which is disposed inside the guardrail of the lifting platform. The mounting bracket forms a receiving cavity with a lateral opening. A control module is disposed inside the receiving cavity. The control module also includes a chassis manipulator and a lifting manipulator that are respectively connected to the controller signal. A detection notch is provided on the top wall of the receiving cavity. The mounting section is disposed inside the receiving cavity and fixedly connected to the mounting bracket. The launch port is positioned directly opposite the detection notch.
[0015] In this embodiment of the application, the mounting bracket is located at the connection of two adjacent fence frames. The mounting bracket includes a base plate, a top plate, and at least two side plates connected between the base plate and the top plate. The base plate, the top plate, and the at least two side plates enclose a receiving cavity with a lateral opening. The two adjacent side plates are respectively connected to the top of the two adjacent fence frames in a one-to-one correspondence. The top plate is provided with a detection notch.
[0016] In this embodiment, the top plate extends out of the two side plates connected to the fence frame, and the portion of the top plate extending out of the side plates is bent to form a connecting groove, which is used to accommodate the fence frame.
[0017] In this embodiment, the anti-collision aerial work equipment also includes an alarm module, which is connected to the controller via a signal. The controller is used to control the alarm module to sound an alarm when the lifting sensor detects a faulty object above or when the chassis sensor detects an obstacle in the surrounding area.
[0018] In this embodiment, the chassis sensor and the lifting sensor are ultrasonic sensors.
[0019] Through the above technical solutions, the anti-collision high-altitude work equipment provided in this application embodiment has the following beneficial effects:
[0020] In the technical solution of this application, the chassis device enables the aerial work platform to move forward or backward. Chassis sensors are installed on the chassis device to detect obstacles around the platform when it moves forward or backward. When the chassis sensors detect an obstacle that is close, the chassis device stops moving, preventing the aerial work platform from colliding with the obstacle during forward or backward movement and improving safety during operation. The lifting platform is mounted on the chassis device in a lifting-driven manner, enabling the aerial work platform to be raised and lowered. Lifting sensors are installed on the lifting platform to detect obstacles above it when the platform is raised or lowered. When the lifting sensors detect an obstacle that is close, the lifting platform stops moving, preventing the aerial work platform from colliding with the obstacle during raising or lowering, thereby improving safety during operation.
[0021] Furthermore, the start / stop switch can independently control the start / stop of the chassis sensors and the lifting sensors. The controller can control the start / stop switch to activate the corresponding sensors based on the working conditions of the aerial work platform, avoiding false alarms caused by information interference, making the use of the collision avoidance aerial work equipment more convenient and reliable. When the aerial work platform is moving forward or backward, the controller controls the start / stop switch to activate the chassis sensors and deactivate the lifting sensors, thereby avoiding false alarms due to information interference from the lifting sensors. When the aerial work platform is raising or lowering, the controller controls the start / stop switch to activate the lifting sensors and deactivate the chassis sensors, thereby avoiding false alarms due to information interference from the chassis sensors.

[0033] Detailed Implementation
[0034] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0035] The descriptions of directions such as "up", "down", "front", "back", "left", and "right" in this application are as follows: Figure 1 The directions shown are for reference only and are used to interpret the location. Figure 1The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.
[0036] The collision avoidance high-altitude work equipment of this application is described below with reference to the accompanying drawings.
[0037] like Figures 1 to 8 As shown, this application provides a collision avoidance aerial work platform, which includes an aerial work platform 10, a sensing module, and a control module 40. The aerial work platform 10 includes a chassis 11 and a lifting platform 12, which is movably mounted on the chassis 11. The sensing module includes a chassis sensor 20 and a lifting sensor 30. The lifting sensor 30 is mounted on the lifting platform 12 and is used to detect obstacles above, while the chassis sensor 20 is mounted on the chassis 11 and is used to detect obstacles around the perimeter. The control module 40 includes a controller 41 and a start / stop switch 42 for starting and stopping the chassis sensor 20 and the lifting sensor 30, respectively. The controller 41 is communicatively connected to the chassis sensor 20, the lifting sensor 30, and the start / stop switch 42, respectively. The controller 41 is used to control the start / stop switch 42 to open the corresponding sensor according to the working conditions of the aerial work platform 10.
[0038] The chassis assembly 11 enables the aerial work platform 10 to move forward or backward. A chassis sensor 20 is installed on the chassis assembly 11. The chassis sensor 20 detects obstacles around the aerial work platform 10 when it moves forward or backward. When the chassis sensor 20 detects an obstacle that is too close, the chassis assembly 11 stops moving to prevent the aerial work platform 10 from colliding with the obstacle during forward or backward movement, thus improving safety during operation. A lifting platform 12 is mounted on the chassis assembly 11 in a lifting-driven manner, enabling the aerial work platform 10 to be raised and lowered. A lifting sensor 30 is installed on the lifting platform 12. The lifting sensor 30 detects obstacles above the aerial work platform 10 when it is raised or lowered. When the lifting sensor 30 detects an obstacle that is too close, the lifting platform 12 stops moving to prevent the aerial work platform 10 from colliding with the obstacle during raising or lowering, thereby improving safety during operation.
[0039] Furthermore, the start / stop switch 42 can control the start / stop of the chassis sensor 20 and the lifting sensor 30 respectively. The controller 41 can control the start / stop switch 42 to open the corresponding sensor according to the working conditions of the aerial work platform 10, avoiding false alarms caused by information interference, making the use of the anti-collision aerial work equipment more convenient and reliable. When the aerial work platform 10 moves forward or backward, the controller 41 controls the start / stop switch 42 to open the chassis sensor 20 and close the lifting sensor 30, thereby avoiding false alarms caused by information interference from the lifting sensor 30. When the aerial work platform 10 is raised or lowered, the controller 41 controls the start / stop switch 42 to open the lifting sensor 30 and close the chassis sensor 20, thereby avoiding false alarms caused by information interference from the chassis sensor 20.
[0040] In the embodiments of this application, please refer to Figure 1 and Figure 2 The chassis sensor 20 includes a front sensor 21 and a rear sensor 22. The front sensor 21 is located on the front side of the chassis device 11 and is used to detect obstacles on the front side. The rear sensor 22 is located on the rear side of the chassis device 11 and is used to detect obstacles on the rear side. The front sensor 21, the rear sensor 22 and the lifting sensor 30 are all equipped with start / stop switches 42.
[0041] A front sensor 21 is installed on the front side of the chassis device 11. The front sensor 21 is used to detect obstacles in front of the aerial work platform 10. When the chassis device 11 moves forward, the start / stop switch 42 turns on the front sensor 21 and turns off the rear sensor 22 and the lifting sensor 30 to avoid information interference and false alarms.
[0042] A rear sensor 22 is installed on the rear side of the chassis device 11. The rear sensor 22 is used to detect obstacles behind the aerial work platform 10. When the chassis device 11 is reversing, the start / stop switch 42 turns on the rear sensor 22 and turns off the front sensor 21 and the lifting sensor 30 to avoid information interference and false alarms.
[0043] When the lifting platform 12 is raised or lowered, the start / stop switch 42 opens the lifting sensor 30 and closes the front sensor 21 and the rear sensor 22 to avoid information interference and false alarms.
[0044] The front sensor 21, the rear sensor 22 and the lifting sensor 30 are each equipped with a start / stop switch 42, so that the start / stop switch 42 can control the start and stop of the front sensor 21, the rear sensor 22 and the lifting sensor 30 respectively without interfering with each other.
[0045] In another embodiment, a start / stop switch 42 can be used to control the start / stop of the front sensor 21, the rear sensor 22, and the lift sensor 30 respectively. For example, an enable switch is a logic switch used to control the activation or pausing of device functions.
[0046] In the embodiments of this application, please refer to Figure 4 The lifting platform 12 includes a scissor lift mechanism 121 and a working platform 122. The scissor lift mechanism 121 is mounted on the chassis device 11. The working platform 122 is located at the end of the scissor lift mechanism 121 away from the chassis device 11. The scissor lift mechanism 121 can lift or lower the working platform 122. A first protective housing 13 is provided in the gap between the chassis device 11 and the scissor lift mechanism 121. The inner cavity of the first protective housing 13 can accommodate the front sensor 21.
[0047] A scissor lift mechanism 121 is mounted on the chassis device 11. A working platform 122 is mounted on the top of the scissor lift mechanism 121, which can raise or lower the working platform 122. A first protective housing 13 is installed in the gap between the chassis device 11 and the scissor lift mechanism 121 when it is lowered to its lowest position. The gap between the chassis device 11 and the scissor lift mechanism 121 refers to the gap between the top of the scissor lift mechanism 121 and the chassis device 11. The first protective housing 13 is installed by making reasonable use of the original gap space of the aerial work platform 10, avoiding the first protective housing 13 from being easily damaged by collisions due to the aerial work platform 10 protruding from it. A front sensor 21 is housed in the inner cavity of the first protective housing 13. The first protective housing 13 can protect the front sensor 21 and prevent rainwater and dust from directly contacting the front sensor 21, thus extending the service life of the front sensor 21.
[0048] Understandably, the front of the first protective housing 13 has an opening so that the front sensor 21 can transmit signals only.
[0049] In the embodiments of this application, please refer to Figure 4 The top wall of the first protective housing 13 is provided with a clearance slope 131, which is inclined downward in the front-to-back direction. By setting the clearance slope 131 to avoid the scissor lift mechanism 121, the first protective housing 13 is prevented from interfering with or obstructing the movement of the scissor lift mechanism 121, and collisions between the scissor lift mechanism 121 and the first protective housing 13 are also avoided during the movement, making the first protective housing 13 more convenient to use.
[0050] In the embodiments of this application, please refer to Figure 5The chassis device 11 has at least two spaced-apart walking steps 111 on its rear side, and a second protective housing 112 is provided at the bottom of one of the walking steps 111. The inner cavity of the second protective housing 112 can accommodate the rear sensor 22.
[0051] At least two walking stairs 111 are spaced apart vertically, providing access for operators to climb onto the work platform 122. A second protective housing 112 is located at the bottom of one of the walking stairs 111, utilizing the space between two adjacent walking stairs 111 to install the second protective housing 112 and preventing operators from stepping on it. The rear sensor 22 is housed within the inner cavity of the second protective housing 112, protecting it from rain and dust and extending its lifespan.
[0052] In the embodiments of this application, please refer to Figure 6 and Figure 7 The lifting sensor 30 includes a sensor body 31 and a third protective housing 32. The third protective housing 32 is disposed on the lifting platform 12 and includes a mounting section 321 and a signal transmitting section 322 arranged sequentially. The sensor body 31 is placed in the mounting section 321 and the signal transmitting head is arranged facing the signal transmitting section 322. The top wall of the signal transmitting section 322 has a transmitting port 3221. The signal transmitting section 322 has a signal reflector 3222 on the side facing the signal transmitting head. The signal reflector 3222 is inclined away from the sensor body 31 in the direction from bottom to top.
[0053] The third protective housing 32 is located on top of the lifting platform 12 and includes a mounting section 321 and a signal transmitting section 322. The mounting section 321 houses the sensor body 31, and the signal transmitting section 322 is connected to the mounting section 321. A transmitting port 3221 is provided on the top wall of the signal transmitting section 322. The signal transmitting head of the sensor body 31 faces the signal transmitting section 322. A signal reflector 3222 is provided on the side of the signal transmitting section 322 facing the signal transmitting head, and the signal reflector 3222 is used to reflect the signal. The signal emitted by the signal transmitting head is reflected by the signal reflector 3222, changing the signal direction upwards to enable the detection of obstacles above. By changing the signal direction through reflection using the signal reflector 3222, the sensor body 31 can be placed inside the mounting section 321. Compared to the sensor body 31 being directly facing upwards, this avoids direct contact between rainwater or dust and the sensor body 31, extending its service life.
[0054] Specifically, a water-draining groove 3223 is provided at the bottom of the signal transmitting section 322, and rainwater flows out through the water-draining groove 3223 after entering the signal transmitting section 3222. It can be understood that the water-draining groove 3223 is misaligned with the controller 40 to prevent rainwater from flowing out of the water-draining groove 3223 and entering the controller 40, which would damage the controller 40.
[0055] In the embodiments of this application, please refer to Figure 6 and Figure 7 The anti-collision aerial work platform also includes a mounting bracket 50, which is located inside the guardrail 123 of the lifting platform 12. The mounting bracket 50 forms a receiving cavity 54 with a lateral opening. The receiving cavity 54 is equipped with a control module 40. The control module 40 also includes a chassis manipulator 43 and a lifting manipulator 44, which are respectively connected to the controller 41. The top wall of the receiving cavity 54 is provided with a detection notch 521. The mounting section 321 is located in the receiving cavity 54 and is fixedly connected to the mounting bracket 50. The launch port 3221 is set directly opposite the detection notch 521.
[0056] An installation bracket 50 is provided on the inner side of the guardrail frame 123 of the lifting platform 12. The installation bracket 50 forms a receiving cavity 54, and the control module 40 is disposed within the receiving cavity 54. The installation and fixation of the control module 40 are achieved by providing the installation bracket 50 with the receiving cavity 54. Furthermore, the control module 40 also includes a chassis manipulator 43 and a lifting manipulator 44, which are respectively signal-connected to the controller 41. The chassis manipulator 43 is used by the operator to control the chassis to move forward or backward, and the lifting manipulator 44 is used by the operator to control the lifting platform 12 to raise and lower. The receiving cavity 54 has a lateral opening facing the inner side of the guardrail frame 123, which facilitates the operator's operation of the chassis manipulator 43 and the lifting manipulator 44. The mounting section 321 is disposed within the receiving cavity 54 and is fixedly connected to the installation bracket 50 to achieve the installation and fixation of the third protective housing 32. The top wall of the receiving cavity 54 is provided with a detection notch 521, and the emission port 3221 is set directly opposite the detection notch 521. By setting the detection notch 521, the signal emitted by the sensor body 31 is reflected only by the signal reflector 3222 and then emitted upward from the emission port 3221 through the detection notch 521, thus avoiding the signal being blocked by the top wall of the mounting bracket 50.
[0057] Understandably, the chassis control 43 can be a handle, and the lifting control 44 can be a push-button switch.
[0058] In the embodiments of this application, please refer to Figure 8The mounting bracket 50 is located at the connection between two adjacent fence frames 123. The mounting bracket 50 includes a base plate 51, a top plate 52, and at least two side plates 53 connected between the base plate 51 and the top plate 52. The base plate 51, the top plate 52, and the at least two side plates 53 enclose a receiving cavity 54 with a lateral opening. The two adjacent side plates 53 are respectively connected to the top of the two adjacent fence frames 123 in a corresponding manner. The top plate 52 is provided with a detection notch 521.
[0059] The mounting bracket 50 is located at the connection point of two adjacent guardrail frames 123, facilitating observation of the sides and bottom of the aerial work platform 10. Placing the control module 40 in a corner frees up valuable space in the center of the aerial work platform 10, which is highly advantageous for placing tools, materials, small equipment, or when multiple people need to collaborate on the aerial work platform 10 simultaneously, preventing the operator from competing for space with the control module 40. The top plate 52 and bottom plate 51 are spaced vertically, and the side plates 53 extend vertically. At least two side plates 53 connect between the top plate 52 and the bottom plate 51. The bottom plate 51, top plate 52, and at least two side plates 53 together form a receiving cavity 54 with lateral openings. Adjacent side plates 53 are respectively connected one-to-one to the top of two adjacent guardrail frames 123, resulting in a larger connection area between the mounting bracket 50 and the guardrail frame 123, thus improving the connection stability between the mounting bracket 50 and the guardrail frame 123.
[0060] In the embodiments of this application, please refer to Figure 8 The top plate 52 extends out of the two side plates 53 connected to the fence frame 123, and the part of the top plate 52 extending out of the side plates 53 is bent to form a connecting groove 522, which is used to accommodate the fence frame 123.
[0061] The top plate 52 extends out of the two side plates 53 connected to the fence frame 123 on its adjacent sides. The part of the top plate 52 extending out of the side plates 53 is bent downward to form a connecting groove 522. By setting the connecting groove 522 to accommodate the fence frame 123, the contact area between the top plate 52 and the fence frame 123 is increased, which prevents the mounting bracket 50 from detaching from the fence frame 123 and improves the connection stability and reliability between the mounting bracket 50 and the fence frame 123.
[0062] In the embodiments of this application, please refer to Figure 3 The anti-collision aerial work platform also includes an alarm module 60, which is connected to the controller 41. The controller 41 is used to control the alarm module 60 to sound an alarm when the lifting sensor 30 detects a faulty object above or when the chassis sensor 20 detects an obstacle in the surrounding area.
[0063] By setting an alarm module 60, operators can be promptly alerted to take action and adjust the direction to avoid collisions between the aerial work platform 10 and obstacles, thereby improving the safety and reliability of the aerial work equipment.
[0064] Specifically, the alarm module 60 can trigger an alarm through sound or light, or both simultaneously.
[0065] In this embodiment, the chassis sensor 20 and the lift sensor 30 are ultrasonic sensors. Ultrasonic sensors have the advantage of strong environmental adaptability and can work in both dark and bright light environments.
[0066] It is understood that in other embodiments, chassis sensor 20 and lift sensor 30 may be configured as infrared sensors, lidar sensors or other sensors.
