Description

Technical Field

[0001] The invention belongs to the technical field of mobile contact networks, and in particular relates to a rotation adjustment device for a mobile contact network arm support structure and an operating method. Background Art

[0002] Existing railway freight loading and unloading stations require gantry cranes to lift cargo. To avoid touching the moving contact network during loading and unloading, existing technologies use a method of directly dumping the columns. However, this method currently has the following shortcomings:

[0003] 1. The arm tilts to the same degree as the column tilts. Due to construction errors such as mechanical structure installation and temperature between the columns, there will be uneven tension between the columns.

[0004] 2. The existing technology directly drives the arm to tilt with the column. When the arm tilts, the tension on the load-bearing cable and the contact line will be converted into a torsion on the arm structure itself, which will cause the arm structure itself to deform.

[0005] 3. The original method of load-bearing cables and contact lines is prone to bending at the wrist arm fixing position, affecting the service life. Summary of the Invention

[0006] To this end, the current problem is how to keep the load-bearing cables and contact lines in a relatively constant tension during the tilting or verticalization of the arm structure; the contact lines and load-bearing cables do not bend during the movement; the arm structure does not suffer from tension deformation; and the load-bearing cables and contact lines can also rise or fall in a relatively parallel manner.

[0007] In order to achieve the above-mentioned purpose, it is necessary to make new innovative improvements to the structure and actuation principle of the existing mobile contact network arm. In view of the shortcomings of the relevant technology, the first aspect of the present invention provides a mobile contact network arm support structure rotation adjustment device, which at least includes

[0014] Furthermore, the rotation adjustment mechanism includes a bearing member;

[0015] The arm support structure is directly or indirectly arranged on the bearing member;

[0016] During the switching process between the tilted state and the upright state, the column is rotationally connected to the whole or part of the bearing member.

[0017] Furthermore, the bearing member is installed in any of the following ways:

[0018] The first type: the bearing member is installed on the column body; or

[0019] The second type: a fixing seat is provided, wherein the fixing seat is provided on the column, and the bearing member is installed on the fixing seat.

[0020] Furthermore, the mounting structure of the bearing member is any one of the following:

[0021] The first type: the bearing member is a first shaft, and the column is rotatably connected to the first shaft;

[0022] or

[0023] The second type: the supporting member is a bearing, and the column is rotationally connected to the bearing.

[0024] Furthermore, during the switching process between the tilted and upright states, the column and the supporting member are rotationally connected, and the supporting member and the arm support structure remain relatively basically non-rotating.

[0025] Furthermore, a control mechanism is included, and the control mechanism is used to control the supporting body to remain basically non-rotating.

[0026] Furthermore, a locking structure is provided in the control mechanism, and when the column switches between the tilted and upright states, the column is rotationally connected to the whole or part of the supporting member; the locking structure is used to control the first axis so that it remains basically stationary; and the arm support structure provided on the first axis drives the conductor to gradually rise or fall when the column switches between the tilted and upright states.

[0027] Furthermore, the locking structure includes at least a first sprocket and a chain, wherein the first sprocket is arranged on the first shaft, and the chain is arranged on the first sprocket, and the first sprocket and the chain cooperate to control the bearing body to remain basically non-rotating.

[0028] Furthermore, it also includes a second sprocket, one end of the chain is arranged on the first sprocket, and the other end of the chain is arranged on the second sprocket.

[0029] Furthermore, it also includes a fixing member, on which the second sprocket is fixed.

[0030] Furthermore, the locking control structure includes a connecting rod mechanism; wherein

[0031] The bearing member serves as a connection point in the linkage mechanism. When the column is pushed or pulled by an external force and switches between the tilting and vertical states, the bearing member body is controlled by the linkage mechanism to remain substantially stationary.

[0032] Furthermore, the connecting rod mechanism includes at least a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod; at least the first, second, third and fourth connecting rods constitute a polygonal connecting rod.

[0033] Furthermore, the first connecting rod, the second connecting rod, the third connecting rod and the fourth connecting rod constitute a quadrilateral connecting rod.

[0034] Furthermore, the connecting rod mechanism has at least first to fourth rotation points, and the first, second, third and fourth rotation points constitute parallelogram force points;

[0035] Furthermore, the fourth connecting rod is a column, and the column is pushed or pulled by an external force. During the switching process between the tilting and vertical states, the first shaft remains basically stationary.

[0036] Furthermore, the rotational connection between the column and the first shaft is the first rotation point, one end of the first connecting rod is fixedly set on the first shaft, and the connection between the other end of the first connecting rod and the second connecting rod is the second rotation point; the connection between the second connecting rod and the third connecting rod is the third rotation point; the rotation point where the column itself is tilted or vertical is the fourth rotation point.

[0037] Furthermore, it also includes a pushing mechanism, which is used to drive the column to tilt or stand upright.

[0038] Preferably, the arm support structure is arranged in any of the following ways:

[0039] The first type: the arm support structure is directly arranged on the bearing member; or

[0040] The second type: it also includes a cantilever base, and the cantilever support structure is arranged on the supporting member through the cantilever base.

[0041] Furthermore, it also includes a second axis, which is a rotating axis. The arm support structure is directly or indirectly arranged on the rotating axis. The arm support structure is subjected to a thrust or a pull so that the arm support structure can be rotated to a working position or a non-working position through the rotating axis.

[0042] Furthermore, when the column is in a tilted state, a vertical state, or when the column switches between the tilted state and the vertical state, the second axis remains perpendicular to the ground.

[0043] Furthermore, it also includes a force transmission mechanism, which is used to transmit the tension or thrust exerted on the bearing cable and / or contact line to the arm support structure, driving the arm support structure to rotate to the working position or non-working position, or switch between the working position and the non-working position.

[0044] Another aspect of the present invention provides a method for operating a mobile contact network arm support structure rotation adjustment device. The method is implemented using the mobile contact network arm support structure rotation adjustment device, and the steps are as follows:

[0045] When the column switches between the tilted state and the upright state, the column and the bearing member can rotate relative to each other;

[0046] The arm support structure is directly or indirectly arranged on the bearing member, and the bearing member body remains substantially stationary during the switching of the column between the tilted state and the upright state;

[0047] When the column switches between the tilted state and the vertical state, the conductor is driven to gradually rise or fall in a basically horizontal state through the arm support structure.

[0048] As a preferred step, the present invention utilizes a locking structure to control the carrier body to remain substantially stationary;

[0049] During the process of switching between the tilted and upright states, the column is rotationally connected to the whole or part of the supporting member; the first axis is controlled by a locking structure so that it remains basically stationary; and the arm support structure arranged on the first axis drives the conductor to gradually rise or fall during the process of switching between the tilted and upright states.

[0050] As a preferred step, the present invention utilizes a chain to control the first axis so that it remains basically stationary; the arm support structure provided on the first axis drives the conductor to gradually rise or fall during the process of the column switching between the tilted and vertical states.

[0051] As a preferred step, the locking control structure in the present invention includes a connecting rod mechanism; the supporting member serves as a connection point in the connecting rod mechanism, and when the column is pushed or pulled by an external force and switches between the tilting and vertical states, the supporting member body is controlled by the connecting rod mechanism to remain basically stationary.

[0052] In the prior art, the arm support structure is rotatably mounted on a column, and the arm support structure can swing above the railway (working position) or to the side of the railway (non-working position). In the present invention, the column needs to be tilted. The advantage of tilting is that it drives the entire mobile contact to the ground, freeing up the space above, which is conducive to cargo loading and unloading, providing a larger cargo loading and unloading space, and at the same time reduces the risk of hoisting equipment contacting the mobile contact network during the original cargo loading and unloading process, such as contacting the contact wire, causing damage to the arm structure, etc. Therefore, tilting the column has great advantages.

[0053] There is no record about this block in the existing current technology. It only provides the tilting of the arm by driving the arm through the column. However, the problems with this method have been explained in the background part. The biggest problem is that during the tilting of the column, the arm structure must also tilt to a corresponding angle. Therefore, the biggest problem to be solved is: during the tilting of the column, the arm support structure remains relatively basically unchanged, so that the load-bearing cable and / or contact line remains basically parallel to the ground during the rising or falling process. For this purpose, it is necessary to provide a new structure, such as the rotation adjustment mechanism added in the present invention, and the rotation adjustment mechanism is arranged on the column. During the tilting of the column, the column and the bearing member of the rotation adjustment mechanism rotate relative to each other, and the bearing member itself does not rotate. The arm support structure is arranged on the bearing member, so that the arm support structure overcomes the tilt.

[0054] In this embodiment, a bearing member is provided at the location where the arm support structure and the column are movably connected, ensuring that the arm support structure remains substantially perpendicular to the ground and prevents tilt. The bearing member serves two primary functions: first, it supports the arm support structure; second, the bearing member allows for a rotational connection between the column and the bearing member, in whole or in part, during tilting or erecting of the column, without the bearing member itself rotating.

[0055] In order to prevent the support member from rotating, a locking structure is provided. The force provided by the locking structure here is an external force provided separately, and its main function is to control the support member from rotating, provide supporting force for the wrist support structure, and effectively support the load-bearing cable and / or contact line set on the wrist support structure. The present invention can effectively overcome the shortcomings of the existing related technologies. During the process of the wrist structure tilting or vertically, the load-bearing cable and the contact line maintain a relatively constant tension; the contact line and the load-bearing cable do not bend during the movement; the wrist structure is not deformed by pulling; the load-bearing cable contact line can also rise or fall in a relatively parallel manner to the ground.

DETAILED DESCRIPTION

[0068] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

[0069] like Figure 1 and Figure 2 As shown, the first aspect of the present invention provides a rotation adjustment device for a mobile contact network arm support structure, which at least includes a column 1, wherein the column 1 has a tilted state and a vertical state, or the column 1 can switch between the tilted and vertical states; Figure 1 is a schematic diagram of the column 1 in a vertical state, Figure 2 It is a schematic diagram of the column 1 in a tilted state.

[0070] This embodiment further includes a rotation adjustment mechanism 2, which is directly or indirectly arranged on the column 1; the column 1 and the rotation adjustment mechanism 2 can rotate relative to each other;

[0071] It should be noted that existing related technologies, including the current patent, do not incorporate a rotation adjustment mechanism 2 on the column 1. Furthermore, the key point is that the column 1 must be rotationally connected to the rotation adjustment mechanism during tilting or vertical adjustment. This technical solution is an innovative solution independently developed and provided by the applicant for the first time. Building on the above solution, the arm support structure 3 is directly or indirectly attached to the rotation adjustment mechanism 2.

[0072] Contact networks are categorized as fixed and mobile. Fixed contact networks are common, such as those located above high-speed rail tracks. Mobile contact networks are used specifically in large freight loading and unloading yards. In existing mobile contact networks, the arm support device is directly or indirectly fixed to a column 1. In existing mobile contact networks, the arm support device is attached to the column 1 via a pivot axis. This pivot axis facilitates the arm support device's swing to the side of or above the track.

[0073] The present invention aims to firstly enable column 1 to tilt or vertically adjust, and secondly, to ensure that column 1 is rotatably connected to rotational adjustment mechanism 2 during the tilting or vertical adjustment process. The key point is that column 1 is rotationally connected to rotational adjustment mechanism 2, and then arm support structure 3 is directly or indirectly mounted on rotational adjustment mechanism 2. Conventional arm support structure 3 achieves left and right lateral swing via a rotating axis, which is a completely different technical solution from the present embodiment, which allows column 1 to be rotatably connected to rotational adjustment mechanism 2 during the tilting or vertical adjustment process.

[0074] As described above, in the process of switching between the tilted and upright states of the column 1 in this embodiment, the column 1 and the whole or part of the rotation adjustment mechanism 2 are rotationally connected.

[0075] As a preferred embodiment, it also includes a conductor, which is directly or indirectly arranged on the arm support structure 3; when the column 1 switches between the tilted and vertical states, the arm support structure 3 drives the conductor to gradually rise or fall in a basically horizontal state.

[0076] As a preferred embodiment, the rotary adjustment mechanism 2 in this embodiment includes a bearing 21; the column 1 and the bearing 21 are rotatably connected in whole or in part. It should be noted that one of the situations in which the whole can be understood is that the outer periphery of the column 1 and the bearing 21 are completely wrapped in the rotation connection, but it is not limited to this. One of the situations in which the part can be understood here is: please refer to Figure 3 The supporting member 21 is mounted on the column through a pair of bearings. The two ends of the supporting member 21 are bearings, and the column is only connected to the bearing part. The rest of the supporting member is not wrapped (or included) by the column. This situation can be understood as a partial rotation connection, but is not limited to this.

[0077] The arm support structure 3 is directly or indirectly arranged on the bearing member 21;

[0078] During the switching process between the tilted state and the upright state, the column 1 and the whole or part of the supporting member 21 are rotationally connected.

[0079] As a preferred embodiment, the carrier 21 in this embodiment is installed in any of the following ways:

[0080] The first type: the bearing member 21 is installed on the main body of the column 1; or

[0081] The second method is to provide a fixing seat 22 , wherein the fixing seat 22 is provided on the column 1 , and the bearing member 21 is installed on the fixing seat 22 .

[0082] As a preferred embodiment, the mounting structure of the carrier 21 in this embodiment is any one of the following:

[0083] The first type: the supporting member 21 is a first axis, and the column is rotationally connected to the first axis; the first axis is basically perpendicular to the plane of the movement trajectory of the column 1 during the tilting and vertical process; that is, the first axis is arranged horizontally and basically remains parallel to the ground.

[0084] or

[0085] The second type: the supporting member 21 is a bearing, and the column 1 is rotationally connected to the bearing.

[0086] This embodiment provides an example of mounting the support member 21 on the fixed seat 22; the principle is essentially the same, and the support member 21 can also be mounted directly on the main body of the column 1. For example, a specific embodiment is provided in which a bearing is provided on the main body of the column 1. The bearing here can be a universal bearing having an outer ring and an inner ring. The outer ring is fixedly connected to the column 1. During the tilting or vertical movement of the column 1, the inner ring remains essentially stationary, and there is a relative rotational relationship between the outer ring and the inner ring. That is, at this time, the column 1 is rotatably connected to the bearing, and the arm support device is then directly or indirectly mounted on the inner ring. The inner ring can also be replaced by a shaft. This provides an embodiment of a bearing, but no corresponding drawings are provided.

[0087] As mentioned above, the bearing member 21 supports the arm support structure 3. It should be noted that the conductor in this embodiment includes a flexible contact wire 5 or a rigid busbar. Under normal circumstances, the conductor includes a load-bearing cable 4 and / or a contact wire 5.

[0088] The catenary cables 4 and / or the contact wires 5 are arranged on the cantilever support structure 3. So far, the above-mentioned solutions are able to solve the technical problems raised.

[0089] See also Figure 1In this state, the arm support structure 3 is located above the railway (working position). The arm support structure 3 first swings to the side of the railway (non-working position), and then the entire arm is lowered by the tilting of the column 1. Of course, the arm support structure 3 can also be rotated from the working position to the non-working position after the column 1 is tilted.

[0090] It is important to note that when the arm support structure 3 is in the working position, it extends axially along the support member 21, with the catenary wires 4 and contact wires 5 tensioning the arm support structure 3 from both ends, preventing the arm from easily flipping. However, the support member 21 and the column 1 are now movable. For example, in strong winds, the arm support structure 3 may have a tendency to flip and shake left and right. The additional force exerted by this tendency may act on the catenary wires 4 and contact wires 5, causing them to bend and shake, affecting the pantograph's power supply.

[0091] Furthermore, when the arm support structure 3 swings from the working position to the non-working position, it rotates laterally of the support member 21. This downward movement of the arm support structure 3 around the support member 21 directly affects the catenary wires 4 and contact wires 5, bending them. Although in the non-working position, prolonged such movement can shorten the service life of the catenary wires 4 and contact wires 5. When the arm support structure 3 returns to the working position, the bent contact wires 5 can affect the pantograph's power supply.

[0092] Therefore, during the transition between the tilted and upright positions of the column 1 in this embodiment, the column 1 and the support member 21 are rotationally connected, while the support member 21 and the arm support structure 3 remain essentially stationary relative to each other. The primary purpose of maintaining essentially stationary rotation is that the weight of the arm support structure 3 acts on the support member 21 regardless of whether the arm support structure 3 is in the working or non-working position. This prevents bending damage to the catenary cables 4 and contact wires 5. Furthermore, the catenary cables and contact wires must remain essentially parallel during the entire working state, rising or descending. Rotation of the support member 21 will cause the arm support structure to rotate about the support member, exerting external forces on the catenary cables and contact wires mounted on the arm support structure, causing them to bend. Therefore, it is necessary to maintain essentially stationary rotation of the support member.

[0093] As an implementation method, in this embodiment, a control mechanism is provided to control the main body of the carrier 21 to remain substantially stationary.

[0094] like Figure 3 and Figure 4As shown, now it is explained in detail that the control mechanism in this embodiment is provided with a locking structure, and during the process of the column 1 switching between the tilted and upright states, the column 1 is rotatably connected to the bearing member 21; the locking structure is used to control the first axis so that it remains basically stationary; the arm support structure 3 provided on the first axis drives the conductor to gradually rise or fall during the process of the column 1 switching between the tilted and upright states.

[0095] As a preferred embodiment, the locking control structure in this embodiment includes at least a first sprocket 13 and a chain 12. The first sprocket 13 is arranged on the first shaft, and the chain 12 is arranged on the first sprocket 13. The cooperation between the first sprocket 13 and the chain 12 controls the main body of the carrier 21 to remain basically non-rotating.

[0096] Preferably, a second sprocket 14 is further included, one end of the chain 12 is arranged on the first sprocket 13 , and the other end of the chain 12 is arranged on the second sprocket 14 .

[0097] Preferably, a fixing member 11 is further included, and the second sprocket 14 is fixed thereon.

[0098] It should be noted that the arrangement of the chain 12 and the sprocket here is so that when the column 1 is tilted or upright, and the sprocket is stationary, the chain 12 can swing from a vertical position to a tilted position or from a tilted position to a vertical position on the sprocket. In this embodiment, the first and second sprockets do not rotate. It should be noted that the fixing member 11 in this embodiment can be set at any position other than the column 1, as long as it can fix the second sprocket 14. As shown in the figure, the fixing member 11 that fixes the second sprocket 14 is separated from the rotation point of the column 1 itself when it tilts, and the fixing member 11 cannot rotate.

[0099] like Figure 5 and Figure 6 As shown, as another preferred embodiment, this embodiment adopts the linkage mechanism 15 to control, and the specific implementation scheme is as follows:

[0100] The locking structure includes a connecting rod mechanism 15;

[0101] The bearing member 21 is a connection point in the linkage mechanism 15. When the column 1 is pushed or pulled by an external force and switches between the tilting and vertical states, the bearing member 21 is controlled by the linkage mechanism 15 to keep the body of the bearing member 21 basically fixed.

[0102] In this embodiment, the linkage mechanism 15 includes at least a first link 151, a second link 152, and a third link 153; at least the first, second, third, and fourth links constitute a polygonal link. Preferably, the first link 151, the second link 152, the third link 153, and the fourth link constitute a quadrilateral link.

[0103] It should be supplemented that the quadrilateral connecting rod in this embodiment may be a quadrilateral connecting rod that is connected first in the structure, or may not be a quadrilateral connecting rod that is connected first in the structure.

[0104] In this embodiment, the connecting rod mechanism 15 has at least first to fourth rotation points, and the first, second, third and fourth rotation points constitute parallelogram force points;

[0105] In this embodiment, a column is used as the fourth connecting rod. When the column 1 is pushed or pulled by an external force, the first shaft remains substantially stationary during the switching process between the tilted state and the vertical state.

[0106] Of course, it should be noted that using a column as the fourth connecting rod is only one embodiment. For example, a fourth connecting rod can be provided on the basis of a column to form a quadrilateral force point structure, which can also achieve the function of this embodiment. However, the best approach is to use the column as the fourth connecting rod.

[0107] Preferably, in this embodiment, the rotational connection between the column 1 and the first axis is the first rotation point 161, one end of the first connecting rod 151 is fixedly set on the first axis, and the connection between the other end of the first connecting rod 151 and the second connecting rod 152 is the second rotation point 162; the connection between the second connecting rod 152 and the third connecting rod 153 is the third rotation point 163; the rotation point of the column 1 itself when it is tilted or vertical is the fourth rotation point 164.

[0108] When the pillar 1 is pulled or pushed by the pushing mechanism 10 to tilt or straighten, the four rotation control points form a quadrilateral force-bearing structure. This refers to the force-bearing structure being a quadrilateral, not a standard quadrilateral in terms of mechanical structure.

[0109] like Figure 5As shown, the straight line formed by the first rotation point 161 and the second rotation point 162 is parallel to the straight line formed by the third rotation point 163 and the fourth rotation point 164. The column 1 is in a parallel state during the switching process between the tilted and upright states. The column 1 and the first axis rotate relative to each other. Bearings can be provided at both ends of the first axis to be rotatably connected to the column 1. One end of the first connecting rod 151 can be fixedly connected to the first axis by means of a pin or the like. The first axis itself does not rotate. In the force-bearing structure in which a quadrilateral shape is formed at the first to fourth rotation points, the tilting of the column 1 causes the quadrilateral shape to change. The above-mentioned connecting rod structure can ensure that the first axis itself does not rotate.

[0110] In addition, as a preferred embodiment, this embodiment further includes a pushing mechanism, which is used to drive the column 1 to tilt or stand upright.

[0111] It should also be added that, in this embodiment, the column 1 is rotatably connected to the base 9, and is pulled or pushed to be upright, tilted, or switched between the vertical and tilted states by a pushing mechanism 10 (such as a hydraulic push rod, an electric push rod, a pneumatic push rod, or other pushing members that can push the column 1 to tilt belong to the pushing mechanism 10).

[0112] The arm support structure 3 in this embodiment is configured in any of the following ways:

[0113] The first type: the arm support structure 3 is directly arranged on the bearing member 21; or

[0114] The second type: further comprising a cantilever base 6, wherein the cantilever support structure 3 is disposed on the bearing member 21 via the cantilever base 6. In order to facilitate installation, the present embodiment provides a method of using the cantilever base 6.

[0115] A second axis is set on the arm base 6, and the second axis here can be a rotation axis 7. The arm support structure 3 is directly or indirectly set on the rotation axis 7. The arm support structure 3 is subjected to a thrust or a pull so that the arm support structure 3 can be rotated to a working position or a non-working position through the rotation axis.

[0116] In the above embodiment, when the column 1 is in the tilted state, the upright state, or when the column 1 switches between the tilted and upright states, the second axis remains substantially perpendicular to the ground. The above first axis remains parallel to the ground.

[0117] like Figure 7 and Figure 8 As shown, Figure 7 The diagram in the figure is a schematic diagram of a structure without using a force transmission mechanism. Figure 8 As shown in Figure 9yes Figure 8 This embodiment also includes a force transmission mechanism 8, which is used to transmit the tension or thrust exerted on the catenary cables 4 and / or contact wires 5 to the cantilever support structure 3, thereby driving the cantilever support structure 3 to rotate to a working position or a non-working position, or to switch between the working position and the non-working position.

[0118] The catenary cables 4 and / or contact wires 5 can be slidably mounted on the cantilever support structure 3. A force transmission mechanism 8 is used to transmit the tension or thrust applied to the catenary cables 4 and / or contact wires 5 to the cantilever support structure 3, thereby driving the cantilever support structure 3 to rotate to a working position or a non-working position, or to switch between the working and non-working positions. The force transmission mechanism 8 is provided with a spring. The tension or thrust applied to the catenary cables 4 and contact wires 5 is transmitted to the spring. The resulting force from the extension or compression of the spring acts directly or indirectly on the cantilever support structure 3, thereby driving the cantilever support structure 3 to move to the working position or the non-working position.

[0119] It should be noted that drag structures and weights can be provided at both ends of the load-bearing cable 4 and the contact wire 5 to drive the arm support structure 3 between the working and non-working positions. This is not the focus of the present invention and will not be discussed in detail. A force transmission mechanism 8 is used in this embodiment. The specific structure and operating principle of force transmission mechanism 8 have been applied for protection in other patents by the applicant and will not be discussed here.

[0120] like Figure 10 As shown, the second aspect of this embodiment provides an operating method for the rotation adjustment device of the mobile contact network arm support structure 3: the operating method adopts the rotation adjustment device of the mobile contact network arm support structure 3 provided by the above embodiment, and the steps are as follows:

[0121] During the switching process between the tilted and upright states, the column 1 and the bearing member 21 can rotate relative to each other;

[0122] The arm support structure 3 is directly or indirectly arranged on the bearing member 21. When the column 1 switches between the tilted and upright states, the bearing member 21 body remains substantially stationary.

[0123] When the column 1 switches between the tilted state and the vertical state, the conductor is driven to gradually rise or fall in a basically horizontal state through the arm support structure 3.

[0124] As a preferred embodiment, in this embodiment, a locking structure is used to control the main body of the carrier 21 to remain substantially stationary.

[0125] During the process of switching between the tilted and upright states, the column 1 is rotatably connected to the supporting member 21; the supporting member 21 (first axis) is controlled by a locking structure so that it remains basically stationary; the arm support structure 3 arranged on the first axis drives the conductor to gradually rise or fall during the process of switching between the tilted and upright states.

[0126] The first control method is to use the chain 12 to control the first axis so that it remains basically stationary; the arm support structure 3 set on the first axis drives the conductor to gradually rise or fall during the process of switching the column 1 between the tilted and vertical states.

[0127] The second control method is that the locking structure includes a connecting rod mechanism 15; the supporting member 21 serves as a connection point in the connecting rod mechanism 15. When the column 1 is pushed or pulled by an external force and switches between the tilting and vertical states, the connecting rod mechanism 15 controls the supporting member 21 body to remain basically stationary.

[0128] The specific working principle of the operating method has been described in detail in the above-mentioned embodiment of the rotary adjustment device, which is referenced here.

[0129] Although embodiments of the invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the invention, and that persons of ordinary skill in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the invention.
