DETAILED DESCRIPTION

[0021] The following combination Figure 1-Figure 3 This application is described in further detail.

[0022] The present application embodiment discloses a lifting device with a ground-mounted double rocker arm and a herringbone auxiliary arm. Figure 1 The lifting device of the ground-mounted double rocker arm with a herringbone auxiliary arm includes a tower cross arm 1, a mast 2, a rocker arm 3 and a herringbone arm unit 4. The rocker arm 3 is rotatably arranged on opposite sides of the mast 2. Among them, the arrangement of the tower cross arm 1 and the mast 2 and the driving method for driving the rocker arm 3 to rotate belong to the existing technology and will not be elaborated here.

[0023] Reference Figure 1To facilitate the installation of the herringbone holding pole monomer 4, the two ends of the tower cross arm 1 are detachably fixed with a base 15 by bolts, anchoring, etc., and two herringbone holding pole monomers 4 are provided. The two herringbone holding pole monomers 4 are located on the opposite sides of the tower cross arm 1, and the base 15 corresponds to the herringbone holding pole monomers 4 one by one. The herringbone holding pole monomers 4 are arranged on the side of the corresponding base 15 away from the mast 2, so that the herringbone holding pole monomers 4 are located above the tower cross arm 1; specifically, the two rocker arms 3 are located between the two herringbone holding pole monomers 4, and the herringbone holding pole monomers 4 are located below the rocker arms 3. The distance from the herringbone holding pole monomers 4 to the mast 2 increases from bottom to top, and the distance from the end of the herringbone holding pole monomer 4 away from the tower cross arm 1 to the mast 2 is greater than the distance from the end of the tower cross arm 1 away from the mast 2 to the mast 2, so that the two herringbone holding pole monomers 4 form a herringbone auxiliary holding pole combination. Among them, the distance from one end of the rocker arm 3 close to the mast 2 to the line connecting the top of the herringbone boom unit 4 close to one side and the top of the mast 2 is less than the length of the rocker arm 3, so as to ensure that the wire rope can be overlapped on the top of the herringbone boom unit 4, the rocker arm 3 and the mast 2.

[0024] When in use, double-wheel pulleys are installed at the top of the mast 2, the top of the two rockers 3 and the top of the two herringbone holding rod monomers 4. Since the tower cross arm 1 extends from the upper end of the herringbone holding rod monomer 4, the rocker 3, the top of the mast 2, the rocker 3, and the herringbone holding rod monomer 4 in sequence will not interfere with the tower cross arm 1, and the tower material can be hoisted in conjunction with the capstan hoisting. Therefore, without changing the length of the rocker 3 in the ground-mounted double rocker holding rod, the hoisting range can be expanded by adding an auxiliary herringbone holding rod, which is suitable for the scene where the tower cross arm 1 is long, and it is convenient to hoist the tower material above the tower cross arm 1 when the length of the tower cross arm 1 exceeds the hoisting range of the rocker 3. At the same time, the herringbone holding rod monomer 4 can share the load of the rocker 3, improve the hoisting capacity, and have strong hoisting stability.

[0025] Reference Figure 1 and Figure 2The herringbone holding pole monomer 4 is rotatably arranged on the base 15, and the rotation axis of the herringbone holding pole monomer 4 is parallel to the rotation axis of the rocker arm 3. Specifically, two vertical plates 17 are relatively fixed on the base 15, and a rotating shaft 7 is fixedly penetrated at the lower end of the herringbone holding pole monomer 4, and the rotating shaft 7 is rotatably penetrated on the corresponding two vertical plates 17. A connecting rope 5 is connected between the herringbone holding pole monomer 4 and the rocker arm 3 close to one side. Specifically, the connecting rope 5 is a steel rope, one end of which is fixed to the top of the rocker arm 3, and the other end is fixed to the top of the herringbone holding pole monomer 4 on the corresponding side. Since the herringbone holding pole monomer 4 has a certain weight, the upper end of the herringbone holding pole monomer 4 always has a tendency to rotate downward under the action of gravity. The connecting rope 5 is used to tighten the herringbone holding pole monomer 4, thereby realizing the relative fixation of the herringbone holding pole monomer 4. When hoisting tower materials, the upper end of the herringbone holding pole monomer 4 is subjected to a downward force, so that the herringbone holding pole monomer 4 has good stability during use. At the same time, when the amplitude of the rocker arm 3 is adjusted according to operational needs, the amplitude of the herringbone boom unit 4 can be synchronously adjusted through the connecting rope 5 to adapt to complex working conditions.

[0026] Reference Figure 1 An inner tension wire 6 is fixed between the herringbone holding pole unit 4 and the base 15. The inner tension wire 6 is located on the side of the herringbone holding pole unit 4 close to the mast 2. Specifically, the inner tension wire 6 is a steel rope. In order to ensure the tension of the inner tension wire 6 when the herringbone holding pole unit 4 adjusts its amplitude, a winch 16 is installed at one end of the base 15 close to the mast 2. One end of the inner tension wire 6 is fixed to the top of the corresponding herringbone holding pole unit 4, and the other end is wound on the winch 16 on the corresponding side, thereby ensuring the tensioning effect of the herringbone holding pole unit 4.

[0027] Reference Figure 2 The rotating shaft 7 spans the base 15, and gears 8 are fixedly sleeved at the opposite ends of the rotating shaft 7. An arc-shaped tooth segment 9 is slidably provided on the side wall of the base 15. The arc-shaped tooth segment 9 corresponds to the gear 8 one by one, and the arc-shaped tooth segment 9 is slidably provided along the vertical direction to reduce the impact on the lifting work; the arc-shaped tooth segment 9 is used to mesh with the corresponding gear 8, and the arc-shaped tooth segment 9 is located below the corresponding gear 8. An adjusting component for adjusting the arc-shaped tooth segment 9 to slide toward or away from the corresponding gear 8 is provided on the base 15.

[0028] Reference Figure 2 A guide rod 18 is fixed to the side of the arc-shaped tooth segment 9 away from the corresponding gear 8. The cross-section of the guide rod 18 is rectangular. A support plate 19 is fixed to the side wall of the base 15. The support plate 19 corresponds to the guide rod 18 one by one. The guide rod 18 is slidably penetrated on the corresponding support plate 19 along the vertical direction. Through the sliding cooperation between the guide rod 18 and the support plate 19, the sliding of the arc-shaped tooth segment 9 can be guided.

[0029] Reference Figure 2In order to facilitate the adjustment of the arc-shaped tooth segment 9 to slide in a direction close to or away from the corresponding gear 8, the adjustment component includes a push spring 10, a pull rope 11, a wind wheel 12, a transmission member and a reset member. The push spring 10 corresponds to the guide rod 18 one by one. The push spring 10 is movably sleeved on the corresponding guide rod 18. One end of the push spring 10 is fixed on the support plate 19, and the other end is fixed on the side of the arc-shaped tooth segment 9 away from the corresponding gear 8. The push spring 10 is used to push the corresponding arc-shaped tooth segment 9 to slide in a direction close to the gear 8.

[0030] Reference Figure 2 The pull rope 11 corresponds to the arc-shaped tooth segment 9 one by one, and one end of the pull rope 11 is fixed to the side of the corresponding guide rod 18 away from the gear 8. The pull rope 11 is used to pull the guide rod 18 and the arc-shaped tooth segment 9 to slide in the direction away from the corresponding gear 8; the wind wheel 12 is rotatably arranged on the side wall of the base 15, and the wind wheel 12 is rotatably arranged in the horizontal direction. The transmission member is arranged on the base 15, and the transmission member is used to reel or unreel the pull rope 11 when the wind wheel 12 rotates. The reset member is arranged on the base 15, and the reset member is used to drive the wind wheel 12 to rotate and reset. The action force of the reset member is greater than the elastic force of the push spring 10. When the wind wheel 12 rotates due to wind force, the transmission member unwinds the pull rope 11.

[0031] Reference Figure 2 , wherein the rotation axis of the wind wheel 12 is perpendicular to the rotation axis of the rotating shaft 7, and each arc-shaped tooth segment 9 corresponds to two wind wheels 12. When there is strong wind force in the direction perpendicular to the rotation axis of the herringbone holding pole unit 4, and the wind force is greater than the force of the reset member, the wind force will drive the windward wind wheel 12 to rotate, so that the transmission member can unwind the pull rope 11, and the corresponding guide rod 18 and the arc-shaped tooth segment 9 are pushed close to the gear 8 by the push spring 10, so that the arc-shaped tooth segment 9 is meshed with the corresponding gear 8, thereby realizing the relative fixation of the herringbone holding pole unit 4 and the tower cross arm 1, so that the herringbone holding pole unit 4 is not easy to shake under the action of wind force perpendicular to its own rotation axis, thereby ensuring construction safety; and the two wind wheels 12 corresponding to the arc-shaped tooth segment 9 are arranged oppositely, so that the arc-shaped tooth segment 9 can be started to slide in the direction close to the corresponding gear 8 under the action of wind force perpendicular to the rotation axis of the herringbone holding pole unit 4.

[0032] Reference Figure 2 and Figure 3In order to facilitate the winding or unwinding of the pull rope 11 when the wind wheel 12 rotates, a fixing plate 20 is fixed to the side wall of the base 15, and the transmission member includes a drum 13, and the drum 13 corresponds to the arc-shaped tooth segment 9 one by one. The drum 13 is located on the side of the corresponding arc-shaped tooth segment 9 and the guide rod 18 away from the gear 8. The drum 13 is rotatably arranged on the fixing plate 20 on the side where the corresponding arc-shaped tooth segment 9 is located, and the rotation axis of the drum 13 is parallel to the rotation axis of the wind wheel 12. One end of the pull rope 11 away from the arc-shaped tooth segment 9 is wound on the corresponding drum 13, and the drum 13 is located between the two wind wheels 12 on the corresponding side. The drum 13 is coaxially fixed with the two wind wheels 12 on the corresponding side, and the winding direction of the pull rope 11 on both sides of the rotating shaft 7 is the same, so that the arc-shaped tooth segments 9 on both sides of the herringbone holding pole monomer 4 can slide synchronously in the same direction; when the wind wheel 12 is rotated by wind force, the wind wheel 12 drives the drum 13 to rotate to unwind the pull rope 11. Specifically, any one of the wind wheels 12 at both ends of the drum 13 can be rotated by wind force, thereby driving the drum 13 to rotate and unwind the pull rope 11 .

[0033] Reference Figure 2 and Figure 3 In order to facilitate the rotation and reset of the wind wheel 12, the reset member includes a reset torsion spring 14, which is movably mounted on the shaft of the drum 13, one end of the reset torsion spring 14 is fixed to the corresponding fixed plate 20, and the other end is fixed to the side wall of the drum 13. The torsion of the reset torsion spring 14 is greater than the elastic force of the push spring 10. The torsion of the reset torsion spring 14 is set according to actual needs. When the reset torsion spring 14 is in a natural state, the arc-shaped tooth segment 9 is disengaged from the corresponding gear 8, and the push spring 10 is in a compressed state.

[0034] During the hoisting process, when there is no wind or the wind force is less than the torque of the reset torsion spring 14, the drum 13 keeps the pull rope 11 taut under the action of the reset torsion spring 14, and the arc-shaped tooth segment 9 disengages from the corresponding gear 8. At this time, the herringbone boom unit 4 is in use and can adjust the amplitude as the rocker arm 3 is adjusted. When wind blows during the hoisting process, if the wind direction is perpendicular to the rotation axis of the herringbone bracket unit 4 and the wind force is greater than the torque of the reset torsion spring 14, the wind force will drive the windward wind wheel 12 to rotate, and the rotation of the wind wheel 12 drives the corresponding reel 13 to rotate synchronously so that the corresponding reel 13 unwinds the pull rope 11, driving the reset torsion spring 14 to deform, and the pulling force of the reel 13 on the pull rope 11 is reduced. Under the thrust of the push spring 10, the arc-shaped tooth segment 9 slides toward the direction close to the corresponding gear 8, so that the arc-shaped tooth segment 9 is meshed with the corresponding gear 8, thereby realizing the relative fixation of the herringbone bracket unit 4 and the tower crossarm 1, so that the herringbone bracket unit 4 is not easy to shake under the action of wind force perpendicular to its own rotation axis, thereby ensuring construction safety.

[0035] The implementation principle of the embodiment of the present application is: during construction, after the tower cross arm 1 is installed, a crane or other lifting equipment is used to install and fix the base 15 with preset arc-shaped tooth segments 9, adjustment components and other components at the preset position of the tower cross arm 1, and then a crane or other lifting equipment is used to lift the herringbone boom monomers 4 in turn and rotate them to the predetermined position of the base 15, so that the gear 8 on the rotating shaft 7 of the herringbone boom monomer 4 is aligned with the corresponding arc-shaped tooth segment 9, wherein the top of the rocker arm 3 is connected to the top of the herringbone boom monomer 4 near one side by a connecting rope 5, and a winch 16 is installed on the side of the base 15 close to the mast 2, and the winch 16 is connected to the top of the herringbone boom monomer 4 by an inner pull wire 6.

[0036] During hoisting, double-wheel pulleys are installed at the top of the mast 2, the top of the two rockers 3 and the top of the two herringbone holding rods 4. Since the tower cross arm 1 extends from the upper end of the herringbone holding rod 4, the two ends of the steel wire ropes arranged along the herringbone holding rod 4, the rocker 3, the top of the mast 2, the rocker 3 and the herringbone holding rod 4 in sequence will not interfere with the tower cross arm 1. Therefore, without changing the length of the rocker 3 in the ground-mounted double rocker holding rod, the installation of a herringbone auxiliary holding rod helps to expand the hoisting range, which is suitable for the case where the tower cross arm 1 is long, and is convenient for hoisting tower materials above the tower cross arm 1 when the length of the tower cross arm 1 is greater than the hoisting range of the rocker 3, and the hoisting stability is strong.

[0037] When wind blows during the hoisting process, if the wind direction is perpendicular to the rotation axis of the herringbone bracket unit 4 and the wind force is greater than the torque of the reset torsion spring 14, the wind force will drive the wind wheel 12 to rotate. The rotation of the wind wheel 12 drives the corresponding reel 13 to rotate synchronously so that the corresponding reel 13 unwinds the pull rope 11. The pulling force of the reel 13 on the pull rope 11 is reduced. Under the action of the push spring 10, the arc-shaped tooth segment 9 slides toward the direction close to the corresponding gear 8 until the arc-shaped tooth segment 9 meshes with the corresponding gear 8, thereby realizing the relative fixation of the herringbone bracket unit 4 and the tower crossarm 1, so that the herringbone bracket unit 4 is not easy to shake under the action of wind force perpendicular to its own rotation axis, thereby ensuring construction safety.

[0038] When the wind force decreases to a level less than the torque of the reset torsion spring 14, the reset torsion spring 14 drives the reel 13 to rotate in the opposite direction to reel in the pull rope 11. The pull rope 11 pulls the corresponding guide rod 18 and the arc-shaped tooth segment 9 to disengage the arc-shaped tooth segment 9 from the corresponding gear 8, thereby facilitating the continued use of the herringbone boom unit 4.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
