Detailed implementation manners

[0035] Next, in combination with the detailed implementation manners, the present application will be further described. It should be noted that, on the premise of non-conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0036] In the description of the present application, it should be noted that for the orientation terms, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the indicated orientation and position relationship are based on the orientation or position relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0037] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence.

[0038] As used in the description and claims of this application, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or apparatus that comprises a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to such process, method, product or apparatus.

[0039] One aspect of the present application provides a tumbler-type iron tower cross-arm hoisting and erection device, as Figures 1 to 3 shown. A preferred embodiment thereof includes a pair of tumbler bases 11, a pair of counterweights 13, and a hoisting balance A-frame. The two tumbler bases 11 can be spaced at a required distance. For example, when the load-bearing member is the cross-arm 22, the distance between the two tumbler bases 11 can be adjusted according to the width of the cross-arm 22. Then, they are fixedly connected through a connecting member 14 to ensure the structural stability of the entire iron tower cross-arm hoisting and erection device 1. When using the iron tower cross-arm hoisting and erection device 1, the tumbler base 11 can be placed on the load-bearing member through the arc-shaped tread surface 110. The hoisting balance A-frame is installed at the front of the corresponding tumbler base 11, and the counterweights 13 are respectively installed at the rear of the corresponding tumbler base 11. Thus, the center of gravity of the entire iron tower cross-arm hoisting and erection device 1 will be located in the middle of the tumbler base 11, and the distances from the center of gravity to the points on the tread surface 110 forward or backward gradually increase. Therefore, the iron tower cross-arm hoisting and erection device 1 can be in an upright hoisting working condition in a natural state.

[0040] It can be understood that the tumbler base 11 adjusts the position of the center of gravity by means of the hoisting balance A-frame and the counterweights 13 at the front and rear positions, and then the arc-shaped tread surface 110 enables the entire iron tower cross-arm hoisting and erection device 1 to have the "tumbler" characteristic. Furthermore, when using the iron tower cross-arm hoisting and erection device 1, the iron tower cross-arm hoisting and erection device 1 can be in an upright posture in a natural state, so that it can be ensured that the iron tower cross-arm hoisting and erection device 1 can definitely be placed on the load-bearing member in a natural upright posture. Compared with the traditional method, the iron tower cross-arm hoisting and erection device 1 of this embodiment can greatly reduce the laying difficulty and improve the use safety. At the same time, the overall structure of the iron tower cross-arm hoisting and erection device 1 is simple, which can effectively reduce the installation cost.

[0041] It should be noted that the distance between the two tumbler bases 11 can be adjusted according to actual needs. The two tumbler bases 11 can disperse the lifting weight of the hoisting balanced guy derrick, so that the gravitational moment of the lifting weight is located between the two tumbler bases 11, thereby ensuring the force stability of the overall structure of the tower cross-arm hoisting and erection device 1 during the lifting process. Moreover, generally two support points are provided for the hoisting balanced guy derrick to share the force and ensure stable hoisting, and the two support points of the hoisting balanced guy derrick can be respectively installed on the two tumbler bases 11.

[0042] It should also be noted that the counterweight 13 is composed of multiple detachable counterweight blocks, and the specific quantity can be selected according to the weight of the hoisting balanced guy derrick, that is, the center of gravity position of the tower cross-arm hoisting and erection device 1 can be balanced by adjusting the weight of the counterweight 13.

[0043] In this embodiment, there are various specific structures for the tread surface 110 that can form the "tumbler" characteristic. For example, the tread surface 110 can be arc-shaped, or for another example, the tread surface 110 can be elliptical arc-shaped. For the convenience of understanding, the following will give a detailed description of these two structures.

[0044] Regarding the arc-shaped tread surface 110, it should be known that the positions of points on the arc to the center of the circle are the same. According to the "tumbler" characteristic, when the tread surface 110 rolls or swings along the bearing member, the distance from the fulcrum where the tread surface 110 contacts the bearing member to the center of gravity of the tower cross-arm hoisting and erection device 1 formed by the cooperation of the hoisting balanced guy derrick and the counterweight 13 needs to change; and when the tread surface 110 is in the upright and stable state, the distance from the tread surface 110 to the center of gravity of the tower cross-arm hoisting and erection device 1 is the shortest. Therefore, when installing the hoisting balanced guy derrick and the counterweight 13, it is necessary to ensure that the center of gravity position of the tower cross-arm hoisting and erection device 1 is below the center of the circle corresponding to the arc of the tread surface 110, so as to ensure that when the tread surface 110 tilts forward or backward along the bearing member, there will be a tendency to tend to the upright state.

[0045] Regarding the elliptical arc-shaped tread surface, as Figures 7 to 9 shown, since the distances from points on the ellipse to the center point are different from those of other points except their own symmetric points. Therefore, when installing the hoisting balanced guy derrick and the counterweight 13, it is only necessary to ensure that the center of gravity of the tower cross-arm hoisting and erection device 1 is located on the minor axis of the ellipse, so as to ensure that when the tumbler base 11 is in the natural straight state, the long axis of the ellipse of the tread surface 110 is parallel to the surface of the bearing member.

[0046] It should be noted that the structures of the above two tread surfaces 110 can both meet the requirements of this application. For the convenience of subsequent description, the structure of the tread surface 110 in this embodiment preferably adopts an elliptical arc structure. For ease of understanding, a specific example will be described in detail below.

[0047] Specifically, as Figures 7 to 9 shown, the equivalent connection point of the hoisting balanced guy derrick and the tumbler base 11 is located on the major axis of the ellipse corresponding to the tread surface 110, and the equivalent connection point of the counterweight 13 and the frame 11 is also located on the major axis of the ellipse corresponding to the tread surface 110. Therefore, the center of gravity G of the tower cross-arm hoisting and erection device 1 is located at the center point of the ellipse of the tread surface 110.

[0048] As Figure 8 shown, when the tumbler base 11 is in an upright position, the fulcrum B of the tread surface 110 and the bearing member is located at the end point of the minor axis of the ellipse. At this time, the front ends of both sides of the tread surface 110 are at the same height. At this time, the gravitational moment generated by the center of gravity of the hoisting balanced guy derrick to the fulcrum B is balanced with the gravitational moment generated by the center of gravity of the counterweight 13 to the fulcrum B.

[0049] As Figure 7 shown, assuming that the front direction is to the left, when the tumbler base 11 tilts forward, the fulcrum A of the tread surface 110 and the bearing member is located at the front position of the ellipse. At this time, the rear end of the tread surface 110 will tilt upward. Correspondingly, the distance from the center of gravity of the hoisting balanced guy derrick to the fulcrum A is shortened, while the distance from the center of gravity of the counterweight 13 to the fulcrum A is increased. Furthermore, the gravitational moment generated by the counterweight 13 is greater than the gravitational moment generated by the hoisting balanced guy derrick. At this time, the tower cross-arm hoisting and erection device 1 as a whole has a tendency to rotate backward, that is, the fulcrum A has a tendency to move to the position of the fulcrum B.

[0050] As Figure 9 shown, when the tumbler base 11 tilts backward, the change in the gravitational moment of the hoisting balanced guy derrick and the counterweight 13 is exactly opposite to that when tilting forward. At this time, the distance from the hoisting balanced guy derrick to the new fulcrum C is increased, and the distance from the counterweight 13 to the new fulcrum C is shortened. Furthermore, the tower cross-arm hoisting and erection device 1 will have a tendency to rotate forward, that is, the fulcrum C has a tendency to move to the position of the fulcrum B.

[0051] It can be understood that based on the above content, it can be seen that regardless of whether the tower cross-arm hoisting and erection device 1 swings forward or backward, it will ultimately tend to an upright position, that is, Figure 8 the position shown. In this way, it can be ensured that when the tower cross-arm hoisting and erection device 1 is hoisted to the top of the tower for use, there is no need for repositioning, and it can maintain an upright position by using the "tumbler" characteristic, which is convenient for the staff to stabilize.

[0052] In this embodiment, asFigure 3 As shown in the figure, the tumbler base 11 includes a frame 111, a support hinge 113 and a balance arm 112. The tread surface 110 is arranged on the frame 111, and the support hinge 113 is installed at the front part of the frame 111 for cooperating to install the hoisting balanced herringbone boom, and the balance arm 112 is installed at the rear part of the frame 111 for cooperating to install the balance weight 13. During actual hoisting operations, in order to facilitate hoisting, the hoisting balanced herringbone boom generally tilts forward, so the lever arm generated by the center of gravity of the hoisting balanced herringbone boom to the fulcrum of the tread surface 110 and the load-bearing member is relatively long, and the corresponding gravitational moment is also relatively large. In order to balance the hoisting balanced herringbone boom, the balance weight 13 also needs to generate a relatively large gravitational moment; there are mainly two ways for the balance weight 13 to increase the gravitational moment. One is to increase the gravity, and the other is to increase the lever arm. In actual hoisting operations, those skilled in the art hope that the weight of the tower cross-arm hoisting and erection device 1 is as light as possible. Therefore, in this embodiment, it is preferably to adopt the method of increasing the lever arm to increase the gravitational moment of the balance weight 13. There are various ways to increase the lever arm. For example, the balance arm 112 can be inclined, or for another example, the balance arm 112 can be L-shaped.

[0053] It should be noted that since the direction of gravity is vertically downward, the lever arm corresponding to the gravitational moment is in the horizontal direction, that is, the horizontal distance from the gravity to the fulcrum. Therefore, when increasing the lever arm of the balance weight 13, it is mainly to change the horizontal distance between the balance weight 13 and the fulcrum.

[0054] It can be understood that from the foregoing content, the equivalent connection points of the hoisting balanced herringbone boom and the balance weight 13 are located on the long axis of the ellipse of the tread surface 110. Therefore, the installation position of the support hinge 113 and the frame 111 is at the front part of the long axis of the ellipse of the tread surface 110, and the installation position of the balance arm 112 is at the rear part of the long axis of the ellipse of the tread surface 110. In order to ensure the stable connection of the balance arm 112, generally, multiple-point connection is required for the balance arm 112. In this way, when the frame 111 tilts, the balance arm 112 can tilt stably with the frame 111. Therefore, installation holes 1110 can be respectively arranged on both sides of the rear part of the frame 111 symmetrically with respect to the long axis of the ellipse, and the balance arm 112 can be fixedly connected to the two installation holes 1110 respectively.

[0055] In this embodiment, as Figure 3 and Figure 4As shown in the figure, a protective plate 1111 is provided on the side of the frame 111 away from the support hinge 113; the size of the protective plate 1111 is larger than the cross-sectional size of the frame 111, that is, the protective plate 1111 extends along the side part of the end face of the frame 111. Thus, when the tower cross-arm hoisting and erection device 1 is placed on the bearing member, the two tumbler bases 11 can be respectively matched with both sides of the bearing member through the protective plate 1111, ensuring that the tower cross-arm hoisting and erection device 1 can always be located on the bearing member. Specifically, the two tumbler bases 11 are symmetrically placed on both sides of the bearing member, and the protective plates 1111 on the two tumbler bases 11 are respectively located on both sides of the bearing member; Figure 2 For example, when the tower cross-arm hoisting and erection device 1 moves leftward as a whole, it will be restricted by the protective plate 1111 on the right tumbler base 11, and vice versa by the protective plate 1111 on the left tumbler base 11. The mounting holes 1110 can be provided on the protective plate 1111 for mounting the balance arm 112.

[0056] In this embodiment, as Figures 3 to 6 shown, a hinge seat 1112 is provided at the front part of the frame 111, and the support hinge 113 is connected to the hinge seat 1112 through a swing structure; the rotational freedom of the support hinge 113 around the hinge seat 1112 is restricted by the swing structure, and the support hinge 113 can swing within a set angular range along the lateral direction of the rotational plane of the hinge seat 1112 through the swing structure.

[0057] It should be known that generally a pair of masts 12 are used for the hoisting balance V-shaped mast. According to different scenarios to be hoisted, the installation methods and dimensions of the masts 12 may be different. For the different gravities generated by the masts 12 in the above cases, the number of counterweight blocks can be increased or decreased through the counterweight 13 to achieve balance. And in the above cases, the masts 12 may be parallel to each other or installed in a V-shape, and the angle between the masts 12 will also change with the change of the length or spacing of the masts 12. Therefore, in order to handle the above situations, in this embodiment, a swing structure is adopted between the support hinge 113 and the frame 111. Thus, in different usage scenarios, the support hinge 113 can adjust the corresponding angle to meet the installation with the masts 12. And the restriction of the rotational freedom of the support hinge 113 around the hinge seat 1112 can ensure that the overturning moment of the masts 12 can be directly transmitted to the frame 111.

[0058] In this embodiment, there are various specific structures of the swing structure that can achieve the above functions. For the convenience of understanding, one of the structures will be described in detail below. As Figures 3 to 6As shown, the cross-section of the hinge seat 1112 is rectangular, and the support hinge 113 is installed on the hinge seat 1112 through a rectangular installation groove 1130. The width of the installation groove 1130 is equal to that of the hinge seat 1112, and the length of the installation groove 1130 is greater than that of the hinge seat 1112, so as to form a swinging structure between the installation groove 1130 and the hinge seat 1112. When the support hinge 113 is subjected to the overturning force of the hoisting balanced guy derrick, due to the equal width of the support hinge 113 and the installation groove 1130, the support hinge 113 remains stationary relative to the hinge seat 1112 in the overturning direction, that is, the rotational freedom of the support hinge 113 around the hinge seat 1112 is restricted. In the overturning plane, or in the lateral direction of the rotational plane, since the width of the installation groove 1130 is greater than the width of the hinge seat 1112, the support hinge 113 can swing; at the maximum swing angle, both sides of the installation groove 1130 along the length direction abut against the corresponding sides of the hinge seat 1112 respectively.

[0059] Specifically, as Figures 3 to 6 shown, the support hinge 113 includes a hinge portion 1131 and an installation portion 1132; the hinge portion 1131 is used for detachably fixing connection with the lower end of the guy derrick 12, and the installation portion 1132 is fixedly connected with the hinge portion 1131, and the two can be arranged parallel to each other or inclined relative to each other. In order to increase the swing angle as much as possible, in this embodiment, it is preferably to arrange the installation portion 1132 and the hinge portion 1131 inclined. Taking Figure 5 as an example, when the hinge portion 1131 is parallel to the overturning plane, that is, the inclination angle is 0, the installation portion 1132 can be matched with the hinge seat 1112 at the right limit position through the installation groove 1130 arranged thereon; when the hinge portion 1131 is inclined to the maximum angle, the installation portion 1132 can be matched with the hinge seat 1112 at the left limit position through the installation groove 1130. In order to ensure the smooth swing of the support hinge 113, the upper side along the length direction of the installation groove 1130 can be set as an arc surface 1133, and then when the support hinge 113 swings, the arc surface 1133 rolls along the corresponding side of the hinge seat 1112.

[0060] In this embodiment, the swing angle of the support hinge 113 can be selected according to actual needs. For example, the swing angle can be 0° to 45°, and the maximum swing angle is preferably 30°. When the swing angle of the support hinge 113 is 0°, that is, when the hinge portion 1131 of the support hinge 113 is parallel to its overturning plane; as Figure 5 shown, the installation portion 1132 is inclined to the right side of the overturning plane and the included angle is α, and the value of the included angle α is preferably 15°. When the swing angle of the support hinge 113 is 30°, that is, when the included angle between the hinge portion 1131 of the support hinge 113 and its overturning plane is 30°; as Figure 6 shown, the installation portion 1132 is inclined to the left side of the overturning plane and the included angle is β, and the value of the included angle β is preferably 15°.

[0061] In this embodiment, as Figures 2 to 6 shown, the connecting member 14 is rod-shaped, and a bushing 1113 is provided on the frame 111. When connecting the two tumbler bases 11, both ends of the connecting member 14 can penetrate through the bushings 1113 on the corresponding frames 111 respectively; then the bushings 1113 and the connecting member 14 can be tightened through the fasteners 114.

[0062] It should be known that locking holes 1114 are provided at both ends of the bushing 1113 and the connecting member 14. A set of locking holes 1114 is provided on the bushing 1113, and multiple sets of locking holes 1114 can be provided at the end of the connecting member 14. The multiple sets of locking holes 1114 are arranged at intervals along the axial direction of the connecting member 14. In this way, the connecting member 14 can align the locking holes 1114 at different positions with the locking holes 1114 on the bushing 1113 according to the different distances between the two tumbler bases 11 and be tightened through the fasteners 114. The specific structure and working principle of the fasteners 114 are well-known technologies to those skilled in the art. Commonly used fasteners 114 are bolts; then threaded holes are provided in the locking holes 1114 on the bushing 1113 and / or the connecting member 14 for fastening cooperation with the bolts.

[0063] It should also be known that the number of locking holes 1114 in each group is at least one. In order to ensure stable connection force, the number of locking holes 1114 in each group is preferably multiple, and the multiple locking holes 1114 are arranged at equal intervals along the circumferential direction.

[0064] In this embodiment, as Figures 3 to 6 shown, the bushing 1113 is arranged inside the hinge seat 1112, and the extension length of the bushing 1113 is greater than the extension length of the hinge seat 1112. A baffle 115 for limiting the support hinge 113 is installed on the shaft section of the bushing 1113 extending out of the hinge seat 1112.

[0065] It can be understood that the installation position of the bushing 1113 can be any position on the frame 111, as long as the connection between the two tumbler bases 11 can be stable. At the same time, after the support hinge 113 is matched with the hinge seat 1112, in order to ensure the safe use of the support hinge 113, the support hinge 113 needs to be limited. A common limiting method is to set a baffle 115 with a size larger than the cross-sectional size of the hinge seat 1112 to limit the support hinge 113. For the installation of the baffle 115, an additional installation structure needs to be set. In order to simplify the structure of the frame 111 and reduce the overall weight of the frame 111, in this embodiment, by installing the bushing 1113 on the hinge seat 1112, the bushing 1113 can be used as the installation structure of the baffle 115 while being fixed to the connecting member 14. After the baffle 115 is installed on the bushing 1113, the fasteners 114 can also limit the installation of the baffle 115.

[0066] In this embodiment, as Figure 11 shown, the tumbler base 11 further includes a traveling assembly 116 installed on the frame 111. The tumbler base 11 can move on the surface of the carrier through the traveling assembly 116 to meet the hoisting requirements.

[0067] It should be known that after the tower cross-arm hoisting and erection device 1 of the present application completes one hoisting, such as the hoisting of the cross-arm 22, the hoisted cross-arm 22 can be fixed to the tower under the operation of the staff. At this time, the hoisted cross-arm 22 is located in the front of the tower cross-arm hoisting and erection device 1, which may affect the next hoisting of the tower cross-arm hoisting and erection device 1. Therefore, the tower cross-arm hoisting and erection device 1 of the present application needs to gradually move forward with the increase of the number of hoistings to ensure that the hoisting balanced gin pole can always exceed the cross-arm 22 on the current tower.

[0068] In this embodiment, there are various specific structures of the traveling assembly 116 that can meet the above functions. For the convenience of understanding, one of the structures will be described in detail below. As Figure 11 shown, the traveling assembly 116 includes a crawler 1161 and a driving device (not shown). The crawler 1161 is installed on the surface of the frame 111 so that the frame 111 is placed on the surface of the carrier through the crawler 1161; the driving device is fixedly installed on the protective plate 1111 and is in transmission cooperation with the crawler 1161 through the driving wheel 1162 at the output end, so that the crawler 1161 can drive the frame 111 to move along the surface of the carrier under the drive of the driving device.

[0069] It should be known that the specific structure and working principle of the driving device are well-known technologies to those skilled in the art, and a common driving device is a motor. The crawler 1161 and the driving wheel 1162 can adopt friction drive or chain drive, and can be selected according to actual needs.

[0070] It can be understood that the lower surface of the frame 111 is the tread surface 110, then the installation position of the driving device only needs to be on the upper protective plate 1111 of the frame 111; the specific installation position can be selected according to actual needs. Since the lower surface of the frame 111 is the tread surface 110, it only needs to ensure that the lower surface of the frame 111 is elliptical arc-shaped. The upper surface of the frame 111 can be linear or elliptical arc-shaped; for the convenience of processing the frame 111 and the transmission of the crawler 1161, in this embodiment, the frame 111 is preferably integrally set as an ellipse.

[0071] It should also be known that, as Figures 7 to 10As shown, when the tower cross-arm hoisting and erection device 1 encounters an obstacle 221 while traveling on the surface of the bearing member; taking the case of encountering an obstacle 221 during forward movement as an example, as Figure 9 shown, after the frame 111 comes into contact with the obstacle 221, the front part is first lifted until the frame 111 completely crosses the obstacle 221. Then, under the "tumbler" characteristic of itself, the frame 111 swings downward at the front part, and due to inertia, the rear part is lifted up, that is Figure 7 shown; after swinging up and down several times, the frame 111 gradually tends to Figure 8 the straight state shown.

[0072] Another aspect of the present application provides a method for using a tower cross-arm hoisting and erection device. As Figures 12 to 18 shown, one preferred embodiment includes the following steps:

[0073] S100: Assemble the tower cross-arm hoisting and erection device 1 on the ground.

[0074] S200: Hoist the assembled tower cross-arm hoisting and erection device 1 along the center of gravity position so that the tower cross-arm hoisting and erection device 1 is lifted to the necking surface or the cross-arm plane of the tower body 21 in a natural upright state, and then set reverse guy wires to stabilize it.

[0075] S300: Use the tower cross-arm hoisting and erection device 1 to hoist the cross-arm 22 located on the ground to the top of the tower body 21 and assemble it.

[0076] S400: After the tower cross-arm hoisting and erection device 1 completes one hoisting, move it along the fixed cross-arm 22 to the front end for the next hoisting until all the cross-arms 22 are hoisted.

[0077] It should be known that there are various types of cross-arms 22 lifted by the tower cross-arm hoisting and erection device 1 of the present application, such as horizontal cross-arms, variable cross-section cross-arms, and inclined cross-arms, etc. For the convenience of understanding, the following will take the tower cross-arm hoisting and erection device 1 hoisting a horizontal cross-arm and an inclined cross-arm once to complete the assembly of the tower as an example to describe the specific use process of the tower cross-arm hoisting and erection device 1 in detail.

[0078] As Figure 12 shown, after the assembly of the tower body 21 of the tower is completed, the tower cross-arm hoisting and erection device 1 that has been assembled on the ground can be hoisted by the tower erection robot 3 used during the assembly of the tower body 21. At this time, the tower erection robot 3 is located at the top of the tower body 21, that is, at the installation height position of the cross-arm 22. The hoisting position of the tower cross-arm hoisting and erection device 1 can be located at or near the center of gravity position of the tower cross-arm hoisting and erection device 1. Thus, during the hoisting process of the tower cross-arm hoisting and erection device 1, that is Figure 13In the state shown, the overall tower cross-arm hoisting and erection device 1 can be in an upright posture. Finally, the tower cross-arm hoisting and erection device 1 is hoisted to the closing surface at the top of the tower body 21 in an upright posture, that is Figure 14 the state shown.

[0079] As Figure 15 shown, when the tower cross-arm hoisting and erection device 1 is hoisted to the top of the tower body 21, the staff at the top of the tower body 21 can place the tower cross-arm hoisting and erection device 1 stably correspondingly. Then, the top of the hoisting balanced derrick boom of the tower cross-arm hoisting and erection device 1 is connected to the tower body 21 in the opposite direction through the guy wire, and at the same time, the tumbler base 11 is connected to the tower body 21 through the traction anchor rope to ensure the stability of the tower cross-arm hoisting and erection device 1 during subsequent hoisting. After the tower cross-arm hoisting and erection device 1 is stabilized, the hoisting balanced derrick boom can hoist the horizontal cross-arm located on the ground through the lifting rope.

[0080] As Figure 16 shown, when the horizontal cross-arm is hoisted to the top of the tower body 21, the staff can fixedly connect the hoisted horizontal cross-arm to the top of the tower body 21. After the horizontal cross-arm is fixed, the guy wire and the traction anchor rope can be loosened, and then the traveling assembly 116 is started to drive the tower cross-arm hoisting and erection device 1 to travel along the horizontal cross-arm to the front end position, and then the guy wire and the traction anchor rope are tied tightly.

[0081] As Figure 17 and Figure 18 shown, the tower cross-arm hoisting and erection device 1 located at the front end of the horizontal cross-arm can release the lifting rope again to hoist the inclined cross-arm located on the ground. When the inclined cross-arm is hoisted to the front end position of the horizontal cross-arm, the staff can fixedly connect the hoisted inclined cross-arm to the front end of the horizontal cross-arm. After the inclined cross-arm is fixed, the tower assembly is completed.

[0082] It should be known that the specific structure and working principle of the tower assembly robot are well-known technologies to those skilled in the art, so they will not be elaborated in detail here.

[0083] The above describes the basic principle, main features and advantages of the present application. Those skilled in the art of this industry should understand that the present application is not limited by the above embodiments.
