Description

Technical Field

[0001] This application relates to the technical field of wind power, and particularly to a fall arrester and a climbing system. Background Art

[0002] Existing non-climbing devices are generally divided into two major parts during the climbing process: the running vehicle body and personnel fall prevention. Personnel fall prevention is a pure mechanical structure. The hook is connected to the human safety belt, and the fall arrester body is connected to the guide rail. The connection established by the personnel safety belt, the fall arrester, and the guide rail forms a fall prevention system during a fall. However, since the fall prevention system is not interlocked with the non-climbing device, if a person violates the regulations and operates the non-climbing device to rise and fall without wearing a safety belt or a fall arrester, there will be no remedial measures in case of a fall.

[0025] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

[0027] To facilitate the understanding of the fall arrester provided by the embodiment of the present application, its application scenario will be described first. The fall arrester provided by the embodiment of the present application is used in a climbing system to provide safety for workers during climbing. In the current climbing system, the climbing-free device cannot recognize the fall arrester, resulting in safety accidents easily occurring when workers perform illegal operations or wear the fall arrester improperly. For this reason, the embodiment of the present application provides a fall arrester to improve the safety of workers when using the climbing system. The following will describe it in detail with specific drawings and embodiments.

[0028] First, refer to Figure 1 and Figure 2, To facilitate the understanding of the fall arrester 100 provided in the embodiments of the present application, its application scenario will be introduced in detail first. The fall arrester 100 provided in the embodiments of the present application is applied to a climbing system, which mainly includes two main components, namely the fall arrester 100 and the climbing-free device 200. Among them, the fall arrester 100 and the climbing-free device 200 are respectively assembled onto the guide rail 300 inside the wind turbine tower, and both the climbing-free device 200 and the fall arrester 100 can slide on the guide rail 300. During use, the staff stands on the climbing-free device 200, and at the same time, the safety belt 400 worn by the staff is assembled to the fall arrester 100. Among them, the climbing-free device 200 can drive itself and the staff to rise, and the fall arrester 100 can also slide along with the guide rail 300 under the pulling of the safety belt 400. In case of an accidental fall, the fall arrester 100 can be locked on the guide rail 300, thereby preventing the staff from falling and providing safety protection.

[0029] Refer to together Figure 2 and Figure 3 , Figure 3 shows a schematic structural diagram of the fall arrester 100 provided in the embodiments of the present application. The main structure of the fall arrester 100 provided in the embodiments of the present application includes a fall arrester body 110 and a hook assembly 120 connected to the fall arrester body 110. When the staff wears the fall arrester 100, the hook assembly 120 is hooked and connected to the safety belt 400 of the staff, and the fall arrester body 110 is slidably assembled on the guide rail 300. When the climbing-free device 200 climbs, the fall arrester body 110 is driven to slide along the guide rail 300 through the safety belt 400. When a falling situation occurs, the fall arrester body 110 can be locked on the guide rail 300, thereby fixing the staff and providing safety protection. It should be understood that the above-mentioned sliding cooperation of the fall arrester body 110 with the guide rail 300 and the locking on the guide rail 300 are both functions of the existing fall arrester 100, and will not be elaborated in detail here.

[0030] Continue to refer to Figure 3 , an electronic tag 111 for indicating that the fall arrester body 110 is recognized by the climbing-free device 200 of the climbing system is fixed on the fall arrester body 110 provided in the embodiments of the present application. The electronic tag 111 can be an RFID (radio frequency identification) tag. When the fall arrester body 110 is assembled to the guide rail 300, an antenna 230 for recognizing the electronic tag 111 is provided on the climbing-free device 200. Thus, when the electronic tag 111 can be recognized through the antenna 230, the controller of the climbing-free device 200 can obtain the information that the fall arrester body 110 is assembled in place. Specifically, refer to together Figure 1 , Figure 2 and Figure 4As shown, an antenna 230 is provided on the non-climbing device 200. The antenna 230 is located on one side of the anti-falling device body 110 and can identify the electronic tag 111 on the anti-falling device body 110 to determine whether the anti-falling device 100 is installed in the climbing system. In addition, since the anti-falling device body 110 can slide relative to the guide rail 300 and can slide relative to the non-climbing device 200, in order to ensure that the antenna 230 can always be in an identified state, the antenna 230 is located on one side of the anti-falling device body 110, and the coverage angle range of the antenna 230 is -α to +α, so as to ensure that the electronic tag 111 can always be within the coverage range of the antenna 230, and ensure that when the anti-falling device body 110 is assembled to the guide rail 300, it can always be identified. Wherein, α can be 50°, 40° or any angle value between 40° and 50°. In one example, the antenna 230 is provided on the handle 220 of the non-climbing device 200. At the same time, the electronic tag 111 is mounted on the side of the anti-falling device body 110 facing the handle 220 so that the electronic tag 111 can be easily identified. If the antenna 230 cannot identify the electronic tag 111 on the anti-falling device body 110, it is determined that the electronic tag 111 is outside the coverage angle range of the antenna 230; if the antenna 230 can identify the electronic tag 111, it is determined that the electronic tag 111 is within the coverage angle range of the antenna 230. If the electronic tag 111 is within the coverage angle range of the antenna 230, it is determined that the anti-falling device body 110 is installed on the guide rail. If the electronic tag 111 is outside the coverage angle range of the antenna 230, it is determined that the anti-falling device body 110 is not installed in place.

[0031] Refer to together Figure 1 , Figure 3 and Figure 5 As shown, the hook assembly 120 of the anti-falling device 100 provided in the embodiment of the present application is used to cooperate with the safety belt 400. Specifically, the hook assembly 120 includes a safety hook 122. When in use, the safety hook 122 is hooked on the hanging ring 410 of the safety belt 400. When the non-climbing device 200 rises, the staff rises with the non-climbing device 200. At the same time, the safety belt 400 is hooked at the hanging place of the safety hook 122 and drives the non-climbing device body 210 to slide through the safety hook 122. The shape and usage method of the safety hook 122 are the same as those of the safety hook 122 in the prior art, so its structure will not be described in detail here.

[0032] The hook assembly 120 provided in the embodiment of the present application further includes a housing 121 that wraps the above-mentioned safety hook 122. The shape of the housing 121 is adapted to the shape of the safety hook 122 to wrap the safety hook 122 and place devices in the space surrounding the safety hook 122.

[0033] To improve the safety of the staff, the hook assembly 120 provided in the embodiment of the present application further includes a pressure detector 123 and a circuit board assembly 124. Among them, both the pressure detector 123 and the circuit board assembly 124 are assembled in the above-mentioned housing 121 to carry the two components through the housing 121. During use, the pressure detector 123 is used to detect the safety belt 400, that is, the pressure detector 123 is used to detect whether the safety belt 400 is hooked on the safety hook 122 to determine whether the staff's safety belt 400 is connected to the fall arrester 100.

[0034] The circuit board assembly 124 is used to send the signal detected by the pressure detector 123 to the climbing aid 200, so that the climbing aid 200 can determine that the fall arrester 100 is connected to the staff's safety belt 400. The controller of the climbing aid 200 can determine the usage status of the fall arrester 100 according to the antenna 230 and the signal detected by the received pressure detector 123, and determine whether to work according to the usage status. Exemplarily, when the antenna 230 of the climbing aid 200 detects the electronic tag 111, it can be determined that the fall arrester body 110 is assembled to the guide rail 300. When the controller of the climbing aid 200 receives the signal of the safety belt 400 detected by the pressure detector 123, it is determined that the staff's safety belt 400 is connected to the hook assembly 120. Therefore, the controller of the climbing aid 200 can control the climbing aid 200 to rise. However, when any of the above signals is not detected, the controller of the climbing aid 200 prevents the climbing aid 200 from rising until the above two signals (the signal of the electronic tag 111 and the signal of the pressure detector 123) are received. It should be understood that the above control logic of the controller of the climbing aid 200 is a conventional technical means in the art. In the embodiment of the present application, only by setting corresponding signal detection devices on the fall arrester 100 to connect the situation of the fall arrester 100 with the signal of the climbing aid 200, the safety of the use of the entire climbing system is ensured.

[0035] In a specific implementation, the pressure detector 123 can be connected to the circuit board assembly 124 through a wire to transmit the signal of the pressure detector 123 through the wire.

[0036] It can be seen from the above description that the fall arrester 100 provided in the embodiment of the present application is provided with an identifiable electronic tag 111 on the fall arrester body 110, and at the same time, a pressure detector 123 for detecting the safety belt 400 is provided in the hook assembly 120, so that during the climbing process of the staff through the climbing aid 200, it is ensured that the staff uses the fall arrester 100 and wears the safety belt 400, improving the safety of the staff during climbing.

[0037] In one possible implementation, the pressure detector 123 is disposed at a position on the housing 121 corresponding to the mounting location of the safety hook 122. To ensure that when the safety belt 400 cooperates with the hook assembly 120, the loop 410 of the safety belt 400 can always press on the pressure detector 123. As can be seen from the above description, when the safety belt 400 is connected to the safety hook 122, the loop 410 of the safety belt 400 is always hooked at the mounting location of the safety hook 122 and applies a certain force. Therefore, when the pressure detector 123 is disposed at the mounting location of the safety hook 122, it can directly detect whether the safety belt 400 is hooked on the safety hook 122. And the pressure detector 123 can continuously detect when the safety belt 400 is worn on the hook assembly 120.

[0038] In a specific setting, a card slot is provided on the housing 121 corresponding to the mounting location of the safety hook 122; the pressure detector 123 includes a pressure chip trigger board 1231 that is snap-fitted into the card slot, and a pressure chip assembly 1232 that is stacked with the pressure chip trigger board 1231; when the safety belt 400 presses the pressure chip trigger board, the pressure chip trigger board presses the pressure chip assembly 1232 and generates a signal of the safety belt 400. Exemplarily, a card slot is provided on the groove wall of the housing 121, and the pressure chip trigger board 1231 is assembled in the card slot and exposed outside the housing 121, so that when the loop 410 of the safety belt 400 is hooked on the hook assembly 120, it can press on the pressure chip trigger board 1231. And the pressure chip assembly 1232 is located inside the housing 121 and is stacked with the pressure chip trigger board 1231. When the pressure chip trigger board 1231 is pressed by the loop 410 of the safety belt 400, the pressure chip trigger board 1231 presses the pressure chip assembly 1232, and the pressure chip assembly 1232 generates a signal indicating that the safety belt 400 has been detected. Specifically, the pressure chip assembly (such as a square thin-film pressure sensor) 1232 is connected to the circuit board assembly 124, the pressure chip assembly 1232 is attached to the pressure chip trigger board 1231 and is located between the mounting location of the safety hook and the pressure chip trigger board 1231. When the pressure chip trigger board 1231 is squeezed, the pressure chip assembly 1232 transmits the signal to the circuit board assembly 124, and the circuit board assembly 124 sends a signal to the controller of the climbing aid 200.

[0039] Continue to refer to Figure 5 and Figure 6, the hook assembly 120 provided by the embodiment of the present application further includes a power supply module, a switch 127, and an indicator light 126. Among them, the switch 127 is used to activate the circuit board assembly 124 from the sleep state. The switch 127 is connected to the input signal terminal of the circuit board assembly 124 in a normally open state, and the circuit board assembly 124 is in a sleep state when not in use. When it is necessary to start the detection function, the switch 127 needs to be pressed in a momentary control manner to activate the circuit board assembly 124, that is, to wake up the circuit board assembly 124. After the circuit board assembly 124 is woken up, it will automatically enter the sleep state after reaching a preset time (such as 10S) to achieve the purpose of power saving. Among them, the time from waking up to sleeping of the circuit board assembly 124 can be determined according to the completion time of the detection. Without affecting the normal detection function, it will directly enter the sleep state after reaching the preset time. When it is necessary to start the detection function again, operate the switch 127 to wake up the circuit board assembly 124. It should be understood that the sleep and wake-up functions of the above circuit board assembly 124 are common sleep and wake-up functions in the prior art, and their functions are similar to the sleep and wake-up of a laptop computer, and will not be elaborated here.

[0040] The power supply module is electrically connected to the circuit board assembly 124, and the circuit board assembly 124 is electrically connected to the pressure detector 123. Therefore, the pressure detector 123 can be powered by the circuit board assembly 124 to ensure its normal operation. In a specific example process, the circuit board assembly 124 is a circuit board, and a signal receiving and processing circuit (such as a signal amplification, filtering, etc. circuit) connected to the pressure detector 123 (specifically the pressure chip trigger board 1231) is provided on the circuit board. In addition, a signal sending circuit (that is, an antenna) is provided on the circuit board assembly to transmit the received seat belt 400 signal to the controller of the climbing-free device 200. It should be understood that the above signal receiving and processing circuit, as well as the signal sending circuit, are conventional circuits in the art and will not be elaborated in the embodiment of the present application.

[0041] The indicator light 126 is used to indicate the working state of the pressure detector 123. The indicator light 126 is electrically connected to the circuit board assembly 124. And the indicator light 126 can indicate different states. Exemplarily, when the switch 127 is turned on, the indicator light 126 lights up. After the pressure chip trigger board 1231 is squeezed (that is, the seat belt 400 is detected), the indicator light 126 goes out. Thus, according to the different display situations of the indicator light 126, the wearing situation of the seat belt 400 can be visually observed. In addition, the indicator light 126 can also be used to indicate other functions. Exemplarily, the indicator light 126 can also exemplify the power condition of the power supply module. For example, when the power supply module uses a battery 125, when the battery 125 has insufficient power or the charging is completed, the indicator light 126 can emit different colored lights to exemplify. Among them, the battery is not limited to using a lithium battery, and other types of power supply batteries such as button batteries can also be used.

[0042] Continue to refer to Figure 3 , the power supply module provided by the embodiment of the present application may include a battery 125 fixed in the housing 121 or an external power supply module externally connected to the housing 121. When the battery 125 is used in the power supply module, a battery 125 compartment is provided on the housing 121, and the battery 125 is fixed in the battery 125 compartment. As Figure 3 shown, a battery 125 compartment is provided in the housing 121, and the battery 125 compartment is located outside the safety hook 122 to have enough space to accommodate the battery 125. In addition, the provided battery 125 will not affect the cooperation between the safety hook 122 and the safety belt 400.

[0043] Similarly, when setting, the power supply module, the switch 127, the indicator light 126 and the circuit board assembly 124 are located outside the safety hook 122. On the one hand, the above components can be located outside the safety hook 122 to avoid interference with the safety belt 400. In addition, the housing 121 also has enough space to accommodate the above components.

[0044] In the embodiment of the present application, the power supply module may further include an external power supply module. At this time, a port may be provided on the housing 121, and the port is electrically connected to the circuit board assembly 124. On the one hand, it can be connected to the external power supply module to realize power supply, and on the other hand, data transmission can also be performed. For example, the port may be a USB port or a common Type C port.

[0045] Continue to refer to Figure 1 , the embodiment of the present application also provides a climbing system, which includes the fall arrester 100 of any one of the above, and a climbing aid 200; wherein, the climbing aid 200 includes a climbing aid body 210 and an antenna 230 provided on the climbing aid body 210, and the antenna 230 can identify the electronic tag 111; it also includes a controller, and the controller is used to receive the electronic tag 111 identified by the antenna 230 and receive the signal of the safety belt 400. Specifically, the cooperation method between the climbing aid 200 and the fall arrester 100 can refer to the description of the fall arrester 100 above, and will not be elaborated here.

[0046] In the above technical solution, by providing an identifiable electronic tag 111 on the fall arrester body 110 and a pressure detector 123 for detecting the safety belt 400 in the hook assembly 120, it is ensured that the staff uses the fall arrester 100 and wears the safety belt 400 during the climbing process of the climbing aid 200, improving the safety of the staff during climbing.

[0047] As an exemplary solution, a warning device may be provided on the non-climbing device 200. The warning device is connected to the controller. When the hook assembly 120 is in use, it monitors whether the fall arrester 100 is connected to the safety belt 400 and sends a signal to the controller of the non-climbing device 200, and the warning device emits a corresponding warning sound. The electronic tag 111 cooperates with the antenna 230 to monitor whether the fall arrester 100 is installed on the guide rail 300. The antenna 230 transmits the signal to the controller of the non-climbing device 200, and the warning device emits a corresponding warning sound, realizing the linkage recognition function of the non-climbing device 200, the safety belt 400 and the fall arrester 100, thereby improving the safety of the staff when using the climbing system.

[0048] One or more embodiments of this specification are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification shall be included within the protection scope of this disclosure.

[0049] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed in this application, and all of them should be covered within the protection scope of this application. Therefore, the protection scope of this application shall be subject to the protection scope of the claims.
