[0042] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0043] It should be noted that although the device schematics illustrate functional module divisions and the flowcharts illustrate logical sequences, in certain circumstances, the steps shown or described may be performed in a sequence that differs from the module divisions in the device or the sequence in the flowcharts. The terms "first," "second," and so on, in the specification, claims, and drawings, are used to distinguish similar items and are not necessarily used to describe a specific sequence or precedence.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0045] Telecommunications towers are a type of signal transmission tower, also known as signal towers or signal towers. They typically include steel structures such as the tower body, platform, lightning rod, ladder, signal transmitter, support structure, and antenna support. The primary function of a telecommunications tower is to support signal transmission and provide support for the transmitting antenna.

[0046] like Figure 1As shown, the tower body of the current telecommunication tower is composed of a plurality of first steel members 1 and second steel members 2 connected together by bolts or the like. The first steel member 1 and the second steel member 2 can specifically be triangular steel. Before building a telecommunication tower, it is usually necessary to carry out concrete foundation construction at the location to be built, and then connect the second steel member 2 to the foundation to form a rectangle, and then continue to build the plurality of first steel members 1 and the plurality of second steel members 2 upward by hoisting, and finally complete the main body of the tower. After the telecommunication tower is put into use, in order to ensure the normal use of the telecommunication tower, staff are required to regularly maintain and inspect the telecommunication tower and the telecommunication equipment installed on the top of the tower.

[0047] Current telecommunications towers typically feature multiple concave panels spaced apart throughout the tower to provide support for workers climbing the tower. However, when climbing these towers, workers' feet are suspended in mid-air as they move from one concave panel to the next, posing a safety hazard. Furthermore, the worker frequently needs to pull levers outward during the climb, making the operation cumbersome and posing a safety hazard.

[0048] In view of this, an embodiment of the present application proposes a climbing assist device to improve the safety of workers when climbing a tower.

[0049] In the embodiments of the present application, the climbing assistance device of the present application is described in detail using the example of climbing a telecommunications tower. It should be understood that the climbing assistance device of the present application can also be used for climbing other towers such as high-voltage power line towers or wind turbine towers, without limitation.

[0050] like Figure 1 and Figure 2 As shown, the telecommunication tower includes a plurality of first steel components 1 and a plurality of second steel components 2, which together constitute the telecommunication tower body. The second steel components 2 are the main supporting structure in the vertical direction of the telecommunication tower body. Triangular steel bars 4 are provided on the side of the second steel components 2, and I-beams 5 are provided at the front ends of the two triangular steel bars 4. A plurality of climbing auxiliary rods 6 are symmetrically provided on the left front part and the right front part of the outer surface of the second steel component 2, and the two climbing auxiliary rods 6 on the same side are at the same horizontal height.

[0051] Furthermore, in order to facilitate climbing the telecommunication tower and to ensure the safety of workers when climbing the telecommunication tower, multiple anti-fall frames 7 are provided at the corners in the middle of the outer surface of the second steel member 2, and climbing auxiliary units 8 are provided on the front of the outer surfaces of the two I-beams 5.

[0052] Before climbing a telecommunications tower, workers must wear a safety harness connected to one end of a safety rope, which is equipped with a metal hook at the other end. Before climbing, they attach the metal hook to the inner cavity of the anti-fall frame 7. Then, they hold onto the climbing assistance rods 6 located on both sides of the second steel member 2 and step on the climbing assistance unit 8 to ascend.

[0053] like Figure 1 and Figure 2 The climbing assist device proposed in the embodiment of the present application includes a guide component and a climbing assist assembly 8. Specifically, there is at least one guide component, which is used to be installed on the tower body. A plurality of first meshing teeth 51 are arranged at intervals along the length direction of the guide component; the number of climbing assist assemblies 8 is greater than or equal to the number of guide components. Figure 3 、 Figure 4 and Figure 5 Each climbing assist assembly 8 includes a limiting mechanism 83, a support member 81, a locking mechanism 834, and a climbing assist shoe 82. The limiting mechanism 83 is mounted on the support member 81 and includes a first guide gear 832 that is constantly engaged with the first meshing teeth 51 in the guide member. The locking mechanism 834 is used to lock the first guide gear 832. The climbing assist shoe 82 is mounted on the support member 81. The first guide gear 832 meshes with the first meshing teeth 51 and can move along the length of the guide member to achieve climbing or descending. By cooperating with the guide member, the limiting mechanism 83 ensures that the first guide gear 832 remains engaged with the first meshing teeth 51, preventing the first guide gear 832 from separating from the guide member and causing danger.

[0054] In an embodiment of the present application, a guide component is installed on the tower body, and the limiting mechanism 83 of the climbing assist component 8 is connected to the guide component so that the climbing assist component 8 can move along the guide component. When the staff climbs, both feet are connected to a climbing assist shoe 82 respectively. After one of the staff's feet pushes upward, the first guide gear 832 of the limiting mechanism 83 can be locked by the locking mechanism 834, and then the support component 81 under the foot is used as a fulcrum to move the other foot upward. The two feet alternate in sequence, so that the climbing assist component 8 moves upward along the guide component, thereby achieving the climbing work. During the upward movement of the climbing assist component 8, the soles of the staff's feet can always be connected to the climbing assist shoe 82. During the entire climbing process, the staff does not need to lower their heads to find the next foothold, which helps to improve the safety of the staff when climbing the telecommunications tower. During the process of climbing a telecommunication tower or moving downward from a telecommunication tower, the support component 81 can be fixed at the position where the worker wants to stop through the cooperation between the limiting mechanism 83 and the locking mechanism 834, and the worker can move up and down by controlling the climbing auxiliary component 8 with his feet without using his hands, so that the worker can remain upright throughout the process, reducing the complexity of the operation and further improving the safety of the worker when climbing.

[0055] In some embodiments of the present application, Figures 2 to 4 As shown, the guide component has a first wall surface and a second wall surface located on the back of the first wall surface. Along the length direction of the guide component, a plurality of first meshing teeth 51 are arranged at intervals on the first wall surface, and a plurality of second meshing teeth 52 are arranged at intervals on the second wall surface. Figure 5 The first guide gear 832 has at least two teeth. The first meshing teeth 51 on the first wall and the second meshing teeth 52 on the second wall are both meshed with at least one first guide gear 832. Each first guide gear 832 is connected to the support member 81. Because the first and second walls of the guide member are each provided with a corresponding first guide gear 832 that cooperates with the first meshing teeth 51 or the second meshing teeth 52, the climbing assist assembly 8 cannot move in a direction perpendicular to the first or second wall, so that the support member 81 can only move along the extension direction of the guide member. In other words, when climbing, the climbing assist assembly 8 can only move along the guide member and cannot separate from the guide member, thereby improving the safety of climbing or descending from the telecommunications tower.

[0056] In some embodiments of the present application, Figure 3 and Figure 4As shown, the support member 81 includes a support portion and a connecting portion, which are connected in an L-shape. Specifically, the support portion is horizontally arranged, and climbing assist shoes 82 are mounted on the support portion to provide support for the worker. The connecting portion is used to connect with the limiting mechanism 83. In other words, the support member 81 can be connected to the guide member through the limiting mechanism 83.

[0057] In some embodiments of this application, see Figures 5 to 7 As shown, the limiting mechanism 83 also includes a first fixed rod 831 and an active unit 833. One end of the first fixed rod 831 is connected to the support member 81. A first guide gear 832 is rotatably mounted on the first fixed rod 831. The active unit 833 is connected to one side of the first guide gear 832. A locking mechanism 834 locks the first guide gear 832 by locking the active unit 833. Specifically, the first guide gear 832 is rotatable relative to the first fixed rod 831. The active unit 833 is fixedly connected to one side of the first guide gear 832, and the first guide gear 832 can drive the active unit 833 to rotate synchronously. It should be understood that when the climbing assist assembly 8 moves upward along the guide member, the locking mechanism 834 does not restrict the rotation of the active unit 833. However, when the climbing assist assembly 8 moves downward along the guide member, the locking mechanism 834 interacts with the active unit 833 and hinders its rotation, thereby locking the first guide gear 832.

[0058] It should be noted that in the aforementioned embodiment, “upward” refers to the direction toward the top of the tower body; and “downward” refers to the direction toward the bottom of the tower body.

[0059] In some embodiments of this application, see Figures 6 to 9 As shown, the active unit 833 includes a fixing ring 8331 and a first latching tooth 8332 . The fixing ring 8331 is sleeved on the first fixing rod 831 and fixedly connected to the first guide gear 832 . The first latching tooth 8332 has multiple first latching teeth 8332 , and the multiple first latching teeth 8332 are spaced apart on the outer circumference of the fixing ring 8331 .

[0060] The locking mechanism 834 includes a locking plate 8346, which is inserted between two adjacent first latches 8332 to prevent the first latches 8332 from rotating in reverse. The "reverse" direction refers to the direction opposite to the rotation direction of the first guide gear 832 when the climbing assist assembly 8 is climbing (i.e., moving upward) along the guide member. Specifically, the locking plate 8346 is positioned between the guide member and the active unit 833. The locking plate 8346 is arc-shaped. When the locking plate 8346 is positioned vertically downward, the end of the locking plate 8346 that contacts the first latches 8332 bends toward the active unit 833.

[0061] In the aforementioned embodiment, when the first guide gear 832 moves upward along the guide member, the first guide gear 832 rotates forward. Figure 6 As the first guide gear 832 rotates counterclockwise, the first latching teeth 8332 can be sequentially inserted between two adjacent first latching teeth 8332. Because the locking plate 8346 is curved near one end of the first latching teeth 8332, when the first latching teeth 8332 rotate forward, the locking plate 8346 can slide out of the first latching teeth 8332 and engage with the next first latching teeth 8332. In other words, when the first guide gear 832 rotates forward, the locking plate 8346 cannot stop the first latching teeth 8332 from rotating. At this time, the locking plate 8346 cannot restrict the rotation of the first guide gear 832. As a result, the climbing assist assembly 8 can move upward along the guide component.

[0062] In the aforementioned embodiment, when the first guide gear 832 moves downward along the guide member, the first guide gear 832 is reversed. Figure 6 The first guide gear 832 shown rotates counterclockwise. When the locking plate 8346 is positioned between two adjacent first latching teeth 8332, the end of the locking plate 8346 closest to the first latching teeth 8332 abuts one of the first latching teeth 8332, while the back of the locking plate 8346 abuts the other first latching tooth 8332. This prevents the first latching teeth 8332 from rotating further, effectively stopping the first latching teeth 8332 from rotating. Because the first latching teeth 8332 are fixedly connected to the first guide gear 832 via the fixing ring 8331, when the first latching teeth 8332 stop rotating, the first guide gear 832 also stops rotating, effectively locking the first guide gear 832. In other words, when the first guide gear 832 rotates in reverse, the locking plate 8346 prevents the first latching teeth 8332 from rotating, locking the first guide gear 832 and securing it to the guide member. At this time, the climbing auxiliary component 8 and the guide component are relatively stationary, and the staff can use the climbing auxiliary component 8 as a fulcrum to continue climbing upward.

[0063] It is understood that in some embodiments, two parallel guide components are installed on the tower body, and each guide component cooperates with a climbing auxiliary component 8. The staff can move along the extension direction of the guide component by alternating the two climbing auxiliary components 8.

[0064] In other embodiments of the present application, the locking mechanism 834 includes a locking pin, and both the first guide gear 832 and the support member 81 are provided with a pin hole that cooperates with the locking pin. The locking pin is inserted into the pin holes of the support member 81 and the first guide gear 832 to lock the first guide gear 832, thereby securing the first guide gear 832 to the guide member. It should be understood that the locking mechanism 834 may be provided with other auxiliary components to control the cooperation between the locking pin and the pin hole to improve operational convenience.

[0065] In some embodiments of this application, see Figure 6 and Figure 7 As shown, the active unit 833 also includes a second latch tooth 8333, which is arranged on the outer periphery of the fixing ring 8331. The radius of the second latch tooth 8333 is greater than the radius of the first latch tooth 8332. The second latch tooth 8333 is used to drive the locking plate 8346 to rotate toward the side close to the second latch tooth 8333 so that the locking plate 8346 can be inserted between the two adjacent first latch teeth 8332.

[0066] In some embodiments of the present application, Figure 3 and Figure 4 As shown, each climbing auxiliary assembly 8 is provided with four limiting mechanisms 83. Figure 5 Each limiting mechanism 83 includes a first guide gear 832, a first fixing rod 831 for supporting the first guide gear 832, and a locking mechanism 834 for limiting the position. Each first fixing rod 831 is provided with a first guide gear 832 at one end away from the housing of the support component 81. A driving unit 833 is sleeved in the middle of each of the four first fixing rods. This driving unit 833 is fixedly connected to the first guide gear 832 mounted on the same first fixing rod 831 and is capable of coaxial rotation with the first guide gear 832. When the worker's foot moves upward and is dragged by the climbing assist shoe 82 to move the first guide gear 832, the four first fixing rods 831 secure the four first guide gears 832 to the first latching teeth 8332 and the second latching teeth 8333, respectively. Driven by the first guide gear 832, the driving units 833 on the same side rotate synchronously with the first guide gear 832. After the climbing assist assembly 8 completes a single movement, the locking structure connects to the active unit 833, restricting the active unit 833 and preventing its rotation, thereby preventing the rotation of the first guide gear 832. With the cooperation of the first latch 8332 and the second latch 8333, the support member 81 (i.e., the climbing assist assembly 8) is finally fixed to the guide member, allowing the worker to continue climbing upward using the support member 81 (i.e., the climbing assist assembly 8).

[0067] In some embodiments of this application, see Figure 6 and Figure 9 As shown, the locking mechanism 834 also includes a second fixed rod 8341 and a reset mechanism 8344. The second fixed rod 8341 is connected to the support component 81, and the locking plate 8346 is rotatably mounted on the second fixed rod 8341. The reset mechanism 8344 is used to drive the locking plate 8346 to rotate toward the side away from the first latch tooth 8332. Specifically, the locking plate 8346 can rotate with the second fixed rod 8341 as the rotation axis; the reset mechanism 8344 provides a reset force for the locking plate 8346 to drive the locking plate 8346 to rotate toward the side away from the first latch tooth 8332 or the second latch tooth 8333. When the locking plate 8346 is not engaged with the first latch tooth 8332 or the second latch tooth 8333, the locking plate 8346 is set vertically and pointing upward. When the first guide gear 832 rotates forward, that is, Figure 6 When the active unit 833 rotates counterclockwise, the second latching tooth 8333 shifts the locking plate 8346, causing the locking plate 8346 to rotate toward the second latching tooth 8333. As the second latching tooth 8333 continues to rotate, the locking plate 8346 separates from the second latching tooth 8333. After separation, the locking plate 8346 sequentially engages with a plurality of first latching teeth 8332 located behind the second latching tooth 8333.

[0068] See also Figure 6 As shown, the first latching teeth 8332 are not distributed over the entire periphery of the fixing ring 8331. That is, as the active unit 833 rotates a certain angle, the locking plate 8346 will separate from the first latching teeth 8332 or the second latching teeth 8333; at the same time, under the action of the reset mechanism 8344, the locking plate 8346 returns to its vertical upward position.

[0069] When the locking plate 8346 is in a vertically upward state, the climbing auxiliary assembly 8 moves downward along the guide member. At this time, the first guide gear 832 is reversed, that is, Figure 6 As shown, the first guide gear 832 rotates clockwise, simultaneously driving the driving unit 833 to rotate clockwise. When the driving unit 833 rotates clockwise, the first latch 8332 or the second latch 8333 cannot move the locking plate 8346 toward the driving unit 833. As a result, the first guide gear 832 can move downward along the guide member, and the climbing assist assembly 8 can now move downward along the guide member.

[0070] In some embodiments of the present application, the locking plate 8346 is arc-shaped, and the locking plate 8346 includes a forward rotation engagement state and a locking state.

[0071] In the forward rotation engagement state, the first guide gear 832 rotates forward, and the locking plate 8346 is located between two adjacent first latch teeth 8332. The locking plate 8346 can be engaged with different first latch teeth 8332, such as Figure 6 As shown. In the figure, along the clockwise direction, the outer circumference of the fixing ring 8331 is sequentially provided with a second latch tooth 8333 and a plurality of first latch teeth 8332 arranged at intervals. When the first guide gear 832 rotates forward, the second latch tooth 8333 first abuts against the locking plate 8346 and drives the locking plate 8346 to rotate toward the end close to the second latch tooth 8333. As the second latch tooth 8333 continues to rotate, the locking plate 8346 separates from the second latch tooth 8333 and abuts against the subsequent plurality of first latch teeth 8332 in sequence. The locking plate 8346 is arc-shaped and the end close to the first latch tooth 8332 is crescent-shaped and the end is bent toward the side of the first latch tooth 8332 abutting against the locking plate 8346. Therefore, the locking plate 8346 will not stop the first latch tooth 8332 from rotating counterclockwise. As a result, the first guide gear 832 can move upward along the guide component. It should be noted that when rotating forward, Figure 6 The first guide gear 832 is shown rotating counterclockwise.

[0072] In the locked state, the first guide gear 832 reverses, and the locking plate 8346 is located between two adjacent first latch teeth 8332, and the locking plate 8346 stops the first latch teeth 8332 from rotating. Figure 6 The first latch tooth 8332 shown rotates clockwise. At this time, the end of the locking plate 8346 close to the first latch tooth 8332 will abut against one of the first latch teeth 8332, and the back of the locking plate 8346 will abut against another adjacent first latch tooth 8332, so that the locking plate 8346 can stop the first latch tooth 8332 from rotating clockwise.

[0073] It should be noted that when the first guide gear 832 rotates forward, the first guide gear 832 can move upward along the guide component, and at this time, the climbing assist component 8 moves upward along the guide component; when the first guide gear 832 rotates reversely, the first guide gear 832 can move downward along the guide component, and at this time, the climbing assist component 8 moves downward along the guide component.

[0074] The forward rotation refers to the rotation direction of the first guide gear 832 when the climbing assist assembly 8 climbs along the guide member.

[0075] In some embodiments of this application, see Figures 9 to 11As shown, the climbing assist assembly 8 further includes a rotation-stopping mechanism 8343 disposed on a side of the locking plate 8346 away from the active unit 833, and the rotation-stopping mechanism 8343 is used to stop the locking plate 8346. Specifically, the climbing assist assembly 8 further includes a connecting frame 8342 connected to the second fixing rod 8341. The rotation-stopping mechanism 8343 is mounted on the connecting frame 8342 and disposed on a side of the locking mechanism 834 close to the guide component. When the reset mechanism 8344 drives the locking plate 8346 away from the first latch 8332, the locking plate 8346 can abut against the rotation-stopping mechanism 8343, thereby preventing the locking plate 8346 from being reset too far, resulting in the second latch being unable to move the locking plate 8346 to rotate, or preventing the locking plate 8346 from directly contacting or engaging with the first latch 8332 after rotating around the second fixing rod 8341 for one or more cycles.

[0076] In some embodiments of this application, see Figures 9 to 11 As shown, the anti-rotation mechanism 8343 includes a limiting post 8385, and the locking mechanism 834 also includes a limiting plate 8345. The locking plate 8346 is mounted on the second fixed rod 8341 via the limiting plate 8345. The limiting plate 8345 has a limiting portion for engaging with the limiting post 8385. Specifically, the limiting plate 8345 is in a circular shape, and the limiting portion has an L-shaped profile. The locking plate 8346 is fixedly connected to the limiting plate 8345. The reset mechanism 8344 drives the limiting plate 8345 to rotate toward the anti-rotation mechanism 8343, causing the limiting portion to engage with the limiting post 8385, thereby limiting the excessive rotation of the locking plate 8346.

[0077] As one of the implementation methods, see Figure 9 and Figure 10 As shown, the limiting mechanism 8343 includes a fixed plate 8381, and the end of the fixed plate 8381 close to the connecting frame 8342 is fixedly connected to the connecting frame 8342, and the lower part of the end of the fixed plate 8381 close to the second fixed rod 8341 is symmetrically provided with a bracket 8382, and the side of the fixed plate 8381 close to the second fixed rod 8341 is provided with two connecting plates 8383 that can rotate relative to the fixed plate 8381, and the two connecting plates 8383 are provided with a limiting column 8385 that can rotate relative to the connecting plate 8383 near the limiting plate 8345. The two connecting plates 8383 and the fixed plate 8381 are provided with a second spring 8384.

[0078] In some embodiments of this application, see Figures 6 to 11 As shown, the device further includes a knocking unit 8334 and a sounding unit 8347. The knocking unit 8334 is connected to the active unit 833, and the sounding unit 8347 is mounted on the locking mechanism 834. The knocking unit 8334 is used to knock the sounding unit. The knocking unit 8334 and the sounding unit 8347 can remind workers to stop, thereby further improving the safety of workers when climbing telecommunication towers.

[0079] In some embodiments of the present application, the knocking unit 8334 includes an elastic connecting member and a knocking hammer 8373, the knocking hammer 8373 is connected to the active unit 833 through the elastic connecting member, the sounding unit 8347 includes a support frame and a sounding member, the support frame is connected to the locking plate 8346, the sounding member is installed on the support frame, and the active unit 833 drives the knocking hammer 8373 to rotate to hit the sounding member.

[0080] For details, see Figure 7 、 Figure 8 and Figure 9 In this embodiment, the striking unit 8334 includes a connecting rod 8371, which is located on the side of the second latch 8333 on the same side, near the inner surface of the vertical portion of the support component 81. A first spring 8372 is provided on the side of the connecting rod 8371 away from the second latch 8333, and a striking hammer 8373 is provided on the side of the first spring 8372 away from the connecting rod 8371. A sounding unit 8347 is provided on the end of the locking plate 8346 near the inner surface of the vertical portion of the support component 71. The sounding unit 8347 includes a support frame and a circular arc-shaped sounding member that produces sound when struck. In this embodiment, the reset mechanism 8344 can be a torsion spring, and the sounding member can be a metal plate.

[0081] When a worker climbs downward, the locking plate 8346 is held in a vertical position by the torsion spring, and the hammer 8373 does not strike the metal plate during rotation. Therefore, the metal plate does not make any sound. When a worker needs a fulcrum during movement, they simply move the climbing assist assembly 8 upward a distance again. Under the action of the second latch 8333, the locking plate 8346 rotates toward the side closer to the first latch 8332. During this process, the hammers 8373 on the first and second latches 8332 and 8333 successively strike the circular arc surface of the metal plate, causing it to make a sound to remind the worker that this area can be used as a fulcrum. At this time, the climbing assist component 8 is moved downward again, and the two adjacent first locking teeth 8332 are locked by the locking plate 8346, thereby fixing the position of the first guide gear 832 to prevent it from rotating; at the same time, under the connection between the limiting mechanism and the guide component, the climbing assist component 8 can be fixed on the guide component, thereby providing support for the staff's legs, so that the staff can continue to operate another climbing assist component 8 and continue to climb downward, and so on, until the staff returns to the ground.

[0082] In the above embodiment, the function of the support frame is to separate the metal plate with the circular arc surface from the locking plate 8346. Thus, when the metal plate with the circular arc surface is struck and emits a sound, the sound transmission is not affected by other factors.

[0083] As a worker climbs upward, the first guide gear 832 rotates within the guide member, driving the second latch 8333 and the plurality of first latches 8332 to rotate synchronously. During this process, the second latch 8333 pushes the arc-shaped locking plate 8346 toward one end of the second latch 8333, allowing the plurality of first latches 8332 to sequentially engage the locking plate 8346. Simultaneously, the hammer 8373 strikes the circular metal plate, producing a sound. The sound of the metal plate alerts the operator that the climbing assist assembly's current position can serve as a fulcrum, prompting the worker to press down on the climbing assist assembly 8, causing the locking plate 8346 to engage the first latch 8332 and thereby causing the first guide gear 832 to remain stationary relative to the guide member. When the first guide gear 832 is stationary relative to the guide member, the climbing assist assembly 8 can serve as a support point, facilitating the worker's operation of another climbing assist assembly 8 to achieve movement within the guide member.

[0084] The preferred embodiments of the present invention are described above with reference to the accompanying drawings, but are not intended to limit the scope of the present invention. Any modifications, equivalent substitutions, and improvements made by those skilled in the art without departing from the scope and essence of the present invention should be within the scope of the present invention.
