[0044] When working, in the prior art, when the pole is installed, the pole is assembled on the ground, then the pole is pulled by a rope to stand up to a vertical state, because the length of the assembled pole is long, the standing construction space required is large, when the construction space is narrow, it is difficult to stand up the long pole, the pole is directly assembled vertically, the construction time is long, and the construction progress is affected, the embodiment of the present application can solve the above problems, and the specific working mode is as follows: the inner pole 5 and the outer pole 3 are arranged, the outer pole 3 can slide outside the inner pole 5 under the sliding connection of the sliding rail 7 and the sliding block 6, the assembled pole can be contracted and lengthened, before the pole stands up, the pole is in a contracted state, the length of the pole is short, the standing construction space required is small, and then the pole assembled can be stood up in a narrow space, and there is no need for later section-by-section installation, and then the construction speed is accelerated;

[0045] And after the outer embracing rod 3 moves to the position of the connecting block 4 at the corresponding height, the outer embracing rod 3 can be supported and positioned on the connecting block 4 at the corresponding height through the automatic supporting mechanism, which not only helps to ensure the stability of the embracing rod as a whole, but also helps to avoid the situation that the rope is always in a pulling and taut state, affecting the service life of the rope.

[0046] As a further implementation scheme of the present application, the rope lifting mechanism comprises a supporting frame 8 and two mounting seats 9, the supporting frame 8 is fixed on the top surface of the inner embracing rod 5, two first pulley seats 10 are fixed on the bottom surface of the supporting frame 8, a fixed pulley 11 is rotatably connected on each of the two first pulley seats 10, two mounting seats 9 are fixed on the inner wall of the inner embracing rod 5, a winding roller 12 is rotatably connected on each of the two mounting seats 9, a motor 13 is coaxially fixed on one side of each of the two winding rollers 12, the motor 13 is fixed on the outer wall of the mounting seat 9, a pulling rope 14 is wound and fixed on each of the two winding rollers 12, a connecting plate 15 is fixed on each of the two pulling ropes 14 after passing through the corresponding fixed pulley 11, and each of the two connecting plates 15 is fixed on the corresponding sliding block 6; when the embracing rod as a whole needs to be lifted, the motor 13 is started, the output shaft of the motor 13 drives the winding roller 12 to rotate, the pulling rope 14 is wound and rolled through the rotation of the winding roller 12, the sliding block 6 is pulled upwards through the cooperation of the fixed pulley 11 and the pulling rope 14, the sliding block 6 slides on the sliding rail 7, the outer embracing rod 3 is moved upwards through the sliding block 6, the embracing rod as a whole is elongated, and the elongation function is completed;

[0047] When the embracing rod as a whole needs to be shortened, the corresponding winding roller 12 is driven in reverse by the motor 13 to loosen the pulling rope 14, and under the action of gravity, the outer embracing rod 3 can automatically slide upwards to complete the shortening function.

[0048] The outer embracing rod 3 is pulled to slide outside the inner embracing rod 5, so that the embracing rod has the functions of elongation and shortening, and by controlling the winding or loosening length of the pulling rope 14, the movement distance of the outer embracing rod 3 is controlled, so that the overall length of the embracing rod can be freely adjusted according to the iron tower assembly construction, which helps to improve the construction progress.

[0049] As a further embodiment of the present application, the automatic supporting mechanism comprises a turnover plate 16 and a positioning groove 17, the turnover plate 16 is rotatably connected to the bottom surface of the outer embracing rod 3 through a connecting mechanism, a vertical plate 18 is fixed to the bottom end of the turnover plate 16, the positioning groove 17 is arranged on the outer wall of the connecting block 4, the vertical plate 18 is inserted into the positioning groove 17, a pulling mechanism is arranged on one side of the turnover plate 16 for pulling the turnover plate 16 to move away from the connecting plate 15, a strip-shaped through groove 19 is arranged on the surface of the turnover plate 16, a plug rod 20 is inserted into the strip-shaped through groove 19, one end of the plug rod 20 is fixed to the outer wall of the outer embracing rod 3 through a mounting plate 21, the other end of the plug rod 20 is fixed to a limiting piece 22, a pushing disc 23 is slidably sleeved on the plug rod 20, a first spring 24 is fixed between the pushing disc 23 and the mounting plate 21, and the first spring 24 is sleeved on the surface of the plug rod 20; in work, under the elastic force of the first spring 24, the pushing disc 23 always has a tendency to move towards the connecting block 4, under the pushing of the pushing disc 23, the turnover plate 16 always has a tendency to move towards the connecting block 4, so that when the rope lifting mechanism pulls the turnover plate 16 to move to the position of the connecting block 4, under the elastic force of the first spring 24, the turnover plate 16 can automatically turn over to the side close to the connecting block 4, when the vertical plate 18 at the bottom end of the turnover plate 16 turns over to contact the connecting block 4, the outer embracing rod 3 is controlled to move downward through the rope lifting mechanism, so that the vertical plate 18 can be inserted into the corresponding positioning groove 17, thereby connecting the outer embracing rod 3 and the inner embracing rod 5 through the vertical plate 18, and supporting the outer embracing rod 3 through the vertical plate 18;

[0050] When it is necessary to adjust the height of the embracing rod as a whole, the outer embracing rod 3 is directly pulled upward through the rope lifting mechanism, so that the vertical plate 18 can be timely separated from the positioning groove 17, and the connection between the outer embracing rod 3 and the inner embracing rod 5 is cancelled, without manual operation to cancel the connection, which is convenient and simple to operate.

[0051] As a further embodiment of the present application, the connecting mechanism comprises two rotating rods 25 and two connecting seats 26, the two connecting seats 26 are fixed to the bottom surface of the outer embracing rod 3, the first displacement grooves 27 are arranged on the side walls of the two connecting seats 26, the two rotating rods 25 are symmetrically fixed to the side walls of the turnover plate 16, and the ends of the two rotating rods 25 are respectively inserted into the corresponding first displacement grooves 27; in work, after the vertical plate 18 at the bottom end of the turnover plate 16 is inserted into the positioning groove 17, the outer embracing rod 3 continues to fall, at this time, the rotating rods 25 on the turnover plate 16 move upward in the first displacement grooves 27, so that the turnover plate 16 is directly in contact with the bottom end of the outer embracing rod 3, avoiding the situation that the position of the rotating rod 25 is broken due to large stress, thereby being beneficial to ensuring the stability of the turnover plate 16.

[0052] As a further embodiment of the present application, the pulling mechanism comprises two electric cylinders 28 and two second accommodating grooves 29, the two second accommodating grooves 29 are symmetrically arranged on the surface of the turnover plate 16, the fixed ends of the two electric cylinders 28 are fixed on the outer wall of the outer embracing rod 3 through the mounting plate 21, and the movable ends of the two electric cylinders 28 are both fixed with a pulling piece 30 after penetrating through the corresponding second accommodating groove 29; in operation, since the turnover plate 16 always has a tendency to move towards the side close to the connecting block 4, the turnover plate 16 is easy to touch the inner embracing rod 5 in the process of the embracing rod contraction, which causes the outer embracing rod 3 to be unable to smoothly descend, thereby affecting the contraction of the embracing rod, and the embodiment of the present application can solve the above problems, and the specific working mode is as follows: before the overall contraction of the embracing rod, the outer embracing rod 3 is first pulled upward by the rope lifting mechanism, so that the vertical plate 18 at the bottom end of the turnover plate 16 is separated from the positioning groove 17, and then the electric cylinder 28 is started to contract, so that the pulling piece 30 at the movable end of the electric cylinder 28 can pull the turnover plate 16 away from the connecting block 4, so that the turnover plate 16 is away from the inner embracing rod 5, thereby preventing the turnover plate 16 from touching the inner embracing rod 5 in the process of the outer embracing rod 3 descending, causing the embracing rod to be stuck and affecting the contraction of the embracing rod.

[0053] And the second accommodating groove 29 can accommodate the movable end of the electric cylinder 28 in the contraction process.

[0054] As a further embodiment of the present application, the bottom end of the outer embracing rod 3 is fixed with a stop rod 31, one side of the stop rod 31 is in contact with the turnover plate 16; in operation, when the turnover plate 16 supports the outer embracing rod 3, since the turnover plate 16 is in an inclined state, the top end of the turnover plate 16 has a tendency to move away from the connecting block 4, causing the rotating rods 25 at both ends of the turnover plate 16 to be under great stress, and the embodiment of the present application can solve the above problems, and the specific working mode is as follows: the stop rod is arranged to directly contact the end of the turnover plate 16 to support and block one side of the turnover plate 16, thereby preventing the rotating rods 25 at both ends of the turnover plate 16 from being under excessive stress and being broken, and further ensuring the stability of the turnover plate 16.

[0055] As a further embodiment of the present invention, each positioning groove 17 has an installation groove 32 on its inner wall, and a limiting plate 33 is inserted into each of the two installation grooves 32. Each limiting plate 33 has a slope on its top surface, and each vertical plate 18 has a limiting groove 34 on its surface. The vertical height of the limiting groove 34 is greater than the thickness of the limiting plate 33. A gas spring 35 is fixed between the limiting plate 33 and the inner wall of the corresponding installation groove 32. A pulling mechanism is provided at the end of each limiting plate 33 away from the corresponding positioning groove 17. When the pulling rope 14 is wound up, the pulling mechanism is used to pull the limiting plate 33 away from the positioning groove 17. During operation, when the entire support rod is in a vertical state, the flip plate 16 can support the support rod externally. 3. Stable positioning is achieved, but during installation, the pole is in a horizontal state, and the flip plate 16 can only limit the external pole 3 in one direction, making it difficult to maintain the overall stability of the pole. This embodiment of the present invention can solve the above problems. The specific working method is as follows: When the vertical plate 18 is inserted into the positioning groove 17, under the guidance of the inclined surface on the top surface of the limiting plate 33, the limiting plate 33 can be pushed to move into the mounting groove 32 to make room. After the vertical plate 18 passes, the limiting groove 34 moves to the position of the limiting plate 33. Under the elastic force of the gas spring 35, the limiting plate 33 can be pushed into the limiting groove 34 to limit the vertical plate 18, thereby ensuring the stability of the pole in a horizontal state.

[0056] When it is necessary to raise the overall height of the mast, the outer mast 3 is pulled upward by retracting the pull rope 14. Since the vertical height of the limiting groove 34 is greater than the thickness of the limiting plate 33, the limiting groove 34 can provide clearance when the limiting plate 33 is pulled away from the positioning groove 17 by the pulling mechanism. This avoids the limiting plate 33 from obstructing the rise of the outer mast 3 when it retracts. Therefore, during the overall extension of the mast, the limiting plate 33 can automatically retract under the linkage of the pull rope 14, thus canceling the restriction on the vertical plate.

[0057] As a further implementation of the present application, the pulling mechanism comprises two extrusion grooves 36 and two through grooves 37, the two extrusion grooves 36 are respectively formed through the surface of the corresponding limiting plate 33, and the two extrusion grooves 36 are respectively vertically inserted with an extrusion block 38, the opposite bottom surface of the two extrusion blocks 38 is respectively formed with a guide surface 39, the top surface of the two extrusion blocks 38 is fixed with an extrusion plate 40, the extrusion plate 40 is vertically and slidingly connected to the surface of the connecting block 4, the two through grooves 37 are symmetrically formed on the surface of the connecting block 4, the two pulling ropes 14 respectively pass through the corresponding through grooves 37, one side of the two through grooves 37 is respectively provided with a second pulley seat 41, the two second pulley seats 41 are fixedly connected to the top surface of the connecting block 4, the two second pulley seats 41 are respectively rotatably connected with a guide roller 42, the two guide rollers 42 are in contact with the surface of the corresponding pulling rope 14, the other side of the through groove 37 is provided with an elastic extrusion mechanism, the elastic extrusion mechanism is used for extruding the pulling rope 14 to the side close to the guide roller 42, one side of the guide roller 42 is coaxially fixed with a first gear 43, one side of the first gear 43 is engaged with a rack 44, and the rack 44 is fixed to the top surface of the extrusion plate 40; in operation, when the pole gripper needs to be elongated, the pulling rope 14 is wound to move downward, under the extrusion action of the elastic extrusion mechanism, the pulling rope 14 is in close contact with the guide roller 42 in the movement process, so that the guide roller 42 is driven to rotate under the friction action of the pulling rope 14 and the guide roller 42, the guide roller 42 drives the first gear 43 to move synchronously in the rotation process, the first gear 43 drives the rack 44 to move downward, so as to extrude the extrusion plate 40 downward, the extrusion plate 40 pushes the extrusion block 38 downward, the limiting plate 33 is pushed downward by the guide surface 39 on one side of the extrusion block 38, and the limiting plate 33 is moved away from the positioning groove 17 under the guidance of the guide surface 39, so as to automatically cancel the positioning of the vertical plate 18, and prevent the limiting plate 33 from blocking the upward movement of the outer pole gripper 3 in the elongation process of the pole gripper;

[0058] When the outer pole gripper 3 needs to be positioned, the pulling rope 14 needs to be wound to pull the outer pole gripper 3 upward, so that the vertical plate 18 moves above the positioning groove 17, and then the pulling rope 14 is loosened to move the outer pole gripper 3 downward, so that the vertical plate 18 is inserted into the positioning groove 17, so it can be seen that when the outer pole gripper 3 is positioned, the pulling rope 14 needs to be wound first, and then loosened;

[0059] And under the meshing action of the first gear 43 and the rack 44, the limiting plate 33 is retracted when the pulling rope 14 is wound, and the limiting plate 33 is extended when the pulling rope is loosened, so that the limiting plate 33 can always be in an extended state after the vertical plate 18 is inserted into the positioning groove 17.

[0060] As a further embodiment of the application, the elastic pressing mechanism comprises a third pulley seat 45, which is slidingly connected to the top surface of the connecting block 4, and a pressing roller 46, which is rotatably connected to the third pulley seat 45 and is in contact with the pulling rope 14. A second spring 47 is fixed to the side wall of the third pulley seat 45, and a connecting piece 48 is fixed to the end of the second spring 47 away from the third pulley seat 45. The bottom end of the connecting piece 48 is fixed to the top surface of the connecting block 4. During operation, the second spring 47 pushes the third pulley seat 45 when the pulling rope 14 moves downward, so that the pressing roller 46 on the third pulley seat 45 moves towards the side close to the pulling rope 14, thereby elastically pressing the pulling rope 14, so that the pulling rope 14 can be close to the guide roller 42, thereby avoiding the situation that the pulling rope 14 is separated from the guide roller 42 during movement.

[0061] As a further embodiment of the application, a limiting strip 49 is fixed to the inner wall of each second standard section 2, and a threading groove 50 is formed in the surface of the limiting strip 49, through which the pulling rope 14 passes. During operation, the pulling rope 14 is inserted into the threading groove 50, and the pulling rope 14 is limited by the threading groove 50, thereby avoiding the situation that the position of the pulling rope 14 deviates during winding, causing the pulling rope 14 to be separated from the guide roller 42.

[0062] Working principle of the application:

[0063] By setting the inner embracing rod 5 and the outer embracing rod 3, and under the sliding connection of the sliding rail 7 and the sliding block 6, the outer embracing rod 3 can slide outside the inner embracing rod 5, so that the embracing rod whole after assembly can be contracted and elongated. Before the embracing rod is erected, the embracing rod whole is in a contracted state, at which time the length of the embracing rod whole is shorter, and the required erection construction space is smaller, thereby facilitating the erection of the embracing rod whole after assembly in a narrow space, and eliminating the need for post-installation, thereby facilitating the acceleration of construction speed. After the embracing rod whole is erected, the outer embracing rod 3 is pulled to slide outside the inner embracing rod 5 by the rope lifting mechanism, so that the length of the embracing rod whole can be freely adjusted according to the tower assembly construction, thereby facilitating the improvement of construction progress. After the outer embracing rod 3 is moved to the position of the connecting block 4 at the corresponding height, the outer embracing rod 3 can be supported and positioned on the connecting block 4 at the corresponding height by the automatic supporting mechanism, which not only facilitates the stability of the embracing rod whole, but also avoids the situation that the rope is always in a pulling and tightening state, affecting the service life of the rope.
