[0032] Tower jacks are a crucial component in wind power equipment technology, primarily used for hoisting the flanges of large wind turbine towers. They serve as auxiliary hoisting tools during tower installation. Currently, before hoisting offshore wind turbine towers, cranes on the turbine installation vessel are required to install the tower jacks. However, the installation of tower jacks is susceptible to adverse sea conditions. For example, in rough seas, the relative movement of the tower transport vessel and the turbine installation vessel can cause difficulties in aligning the connecting bolts between the tower jack and the tower flange, hindering normal tower hoisting.

[0033] Based on this, this application provides an auxiliary tower crane mounting bracket. The mounting bracket is moved closer to the tower via a movable component. The installation height of the operating platform is adjusted according to the installation height of the tower flange, so that the operating platform is connected to the corresponding support component. The lifting equipment then lifts the tower crane, aligning it with the tower flange. Construction workers stand on the construction platform to align and install the tower crane with the tower flange. Since the mounting bracket and the tower are located on the same transport vessel, they are less prone to relative undulation under adverse sea conditions, thus improving the accuracy of the alignment between the tower crane and the tower flange.

[0034] like Figure 1 and Figure 2 As shown, this application provides an auxiliary tower crane mounting bracket 100, including a mounting bracket 100, a hoisting device 200 on the top of the mounting bracket 100, the hoisting device 200 being used to drive the tower crane to rise and fall so that the tower crane is connected to the tower flange, a plurality of support components 300 being provided on the mounting bracket 100, each support component 300 being arranged sequentially at intervals along the height direction of the mounting bracket 100, an operating platform 400 being provided on the support component 300, one of the operating platforms 400 being connected to the support component 300 to adjust the height of the operating platform 400, a movable component 500 being provided at the bottom of the mounting bracket 100, the movable component 500 being configured to be locked on the mounting bracket 100 after sliding, the movable component 500 being used to drive the mounting bracket 100 to move.

[0035] Understandably, the hoisting equipment 200 can drive the sleeve jack to rise and fall, moving the tower jack to the same elevation as the tower flange. The moving component 500 can drive the mounting bracket 100 to move, ensuring the tower jack and tower flange are aligned. Based on the installation height of the tower flange, the installation height of the operating platform 400 is adjusted, connecting it to the corresponding support component 300. The hoisting equipment 200 then hoists the tower jack, aligning it with the tower flange. Construction workers stand on the platform to align and install the tower jack with the tower flange. Since the mounting bracket 100 and the tower are located on the same transport vessel, they are less prone to relative undulation under adverse sea conditions, thus improving the accuracy of the alignment between the tower jack and tower flange.

[0036] like Figure 1 As shown, in one possible embodiment, the moving component 500 includes a plurality of moving wheels 510 mounted on the bottom of the mounting bracket 100.

[0037] In this embodiment, the caster wheel 510 is a swivel caster, but it can also be any other pulley with a braking function. There are four caster wheels 510, each located near one of the four corners of the mounting bracket 100, thereby improving the stability of the mounting bracket 100. The caster wheels 510 facilitate the movement and braking of the mounting bracket 100, allowing for initial alignment between the tower crane base and the tower flange.

[0038] like Figure 1 As shown, in one possible embodiment, the mounting bracket 100 includes a bottom support frame 110, which includes at least two crossbars 111. Two adjacent crossbars 111 are connected by at least two longitudinal bars 112, and each longitudinal bar 112 is arranged at intervals along the length direction of the crossbars 111.

[0039] Specifically, the bottom support frame 110 includes two horizontal bars 111 and two vertical bars 112. The two vertical bars 112 are vertically fixed between the two horizontal bars 111. The horizontal bars 111 and the vertical bars 112 provide support for the mounting bracket 100. The more horizontal bars 111 and vertical bars 112 there are, the larger the contact area between the bottom support frame 110 and the ground, and the more stable the mounting bracket 100 will be. This makes it less likely for the mounting bracket to sway on the tower transport ship, thereby improving the accuracy of the docking between the tower crane and the tower flange.

[0040] like Figure 1As shown, in one possible implementation, the mounting bracket 100 further includes a central support frame 120, which includes at least four support columns 121. The support columns 121 are vertically fixed on the bottom support frame 110. Multiple support blocks 310 are sequentially spaced on the support columns 121, and the support blocks 310 located in the same plane form a support assembly 300.

[0041] Specifically, four support columns 121 are vertically fixed on two horizontal bars 111 respectively, and the two support columns 121 on the same horizontal bar 111 have different heights. A suspension rod 122 is connected between the ends of the two higher support columns 121. The hoisting equipment 200 is connected to the suspension rod 122. The hoisting equipment 200 can be an electric hoist, electric winch, etc. The hoisting equipment 200 can be used to hoist the tower support and adjust the height of the tower support, so as to facilitate the docking of the tower support with tower flanges of different heights, thereby improving the applicability of the mounting bracket 100.

[0042] The support block 310 provides support for the operating platform 400, while multiple support components 300 can adjust the erection height of the operating platform 400. For the installation of tower cranes of different heights, the construction personnel need to adjust the height of the operating platform 400 accordingly and erect the operating platform 400 on the corresponding support components 300, so that the construction personnel can stand on the operating platform 400 to install tower cranes on tower flanges of different heights.

[0043] like Figure 2 As shown, in one possible implementation, the support block 310 has a slot 320 for the operating platform 400 to be inserted into.

[0044] Understandably, the support block 310 has a snap-fit ​​groove 320, and the operating platform 400 can snap into the snap-fit ​​groove 320. The inner wall of the snap-fit ​​groove 320 limits the operation platform 400, making it less likely for the operation platform 400 to slide in the horizontal direction of the support component 300, reducing the possibility of the operation platform 400 slipping off the support block 310, and improving the stability of the operation platform 400 installation.

[0045] like Figure 2 As shown, in one possible implementation, a plurality of reinforcing components 600 are also included, which are disposed on the mounting bracket 100 and correspond to support components 300.

[0046] like Figure 2 As shown, in one possible implementation, the reinforcing component 600 includes a plurality of reinforcing rods 610, which are located below and connected to the support block 310.

[0047] Specifically, the two ends of the reinforcing rod 610 are fixedly connected to the support column 121 on the same crossbar 111. The reinforcing rod 610 can improve the stability of adjacent support columns 121. At the same time, the reinforcing rod 610 is located below the support block 310, and the reinforcing rod 610 provides support for the support block 310, reducing the possibility of the support block 310 separating from the support column 121. On the other hand, the reinforcing rod 610 can also serve as a step to facilitate construction personnel to climb onto the operating platform 400 to install the tower crane seat.

[0048] like Figure 2 As shown, in one possible implementation, the reinforcing assembly 600 also includes a plurality of support rods 620, each support rod 620 being connected to two adjacent support columns 121, and the support rods 620 and the hoisting equipment 200 being located on opposite sides of the operating platform 400.

[0049] For example, multiple support rods 620 can be arranged in parallel between two adjacent support columns 121. The two ends of the support rods 620 are vertically connected to the two adjacent support columns 121 respectively. The support rods 620 can improve the structural stability between the two adjacent support columns 121, making it difficult for the support columns 121 to move relative to each other. At the same time, the support columns 121 can also be used as steps to facilitate construction personnel to climb onto the operating platform 400.

[0050] For example, every two support rods 620 are intersected between two adjacent support columns 121 to form scissor bracing, thereby improving the overall stability of the mounting bracket 100.

[0051] like Figure 3 As shown, in one possible implementation, a slider 520 is fixedly connected to the fixed seat of the movable wheel 510, a groove 530 for sliding the slider 520 is provided on the side wall of the mounting bracket 100, and a locking member 540 for fixing the slider 520 is provided on the mounting bracket 100.

[0052] During use, when the slider 520 slides to the bottom wall of the groove 530, the moving wheel 510 comes into contact with the ground, and the weight of the mounting bracket 100 is concentrated on the moving wheel 510. The slider 520 is fixed by the locking piece 540, making it easy for construction personnel to push the mounting bracket 100. After the mounting bracket 100 has moved, the locking piece 540 is removed. Under the action of gravity, the mounting bracket 100 moves downward, causing the bottom support frame 110 to contact the ground. The moving wheel 510 receives a reaction force from the ground, causing the slider 520 to move vertically upward in the groove 530. At this time, the weight of the mounting bracket 100 is concentrated on the bottom support frame 110, reducing the possibility of increased gravity on the mounting bracket 100 during construction, which could damage the moving wheel 510.

[0053] like Figure 3As shown, in one possible implementation, the locking member 540 includes a locking screw threaded to the side wall of the mounting bracket 100, one end of which passes through the mounting bracket 100 and is threaded to the slider 520.

[0054] During use, when the slider 520 slides to the bottom wall of the groove 530, the locking screw is turned so that the end of the locking screw passes into the groove 530 and is threadedly connected to the slider 520, thereby fixing the slider 520 in the groove 530.

[0055] In summary, this application provides an auxiliary tower crane mounting bracket. In use, the mounting bracket 100 is lifted, causing the slider 520 to slide to the bottom wall of the slide groove 530. The moving wheel 510 moves along with the slider until the moving wheel 510 moves to the bottom of the mounting bracket 100 and contacts the ground. Then, the locking member 540 is inserted into the mounting bracket 100 and threadedly connected to the slider 520, making it difficult for the slider 520 to move in the slide groove 530.

[0056] The lifting force on the mounting bracket 100 is removed, and the weight of the mounting bracket 100 is concentrated on the multiple moving wheels 510. The mounting bracket 100 is pushed to the tower fan, so that the hoisting equipment 200 corresponds to the tower flange. The locking piece 540 is pulled out from the slider 520, and the bottom support frame 110 moves down and contacts the ground under the action of gravity. The moving wheels 510 are driven by the reaction force of the ground to move the slider 520 vertically upward in the slide groove 530 until the moving wheels 510 are only subjected to their own weight and the weight of the slider 520 and the friction between the slider 520 and the slide groove 530. This reduces the weight of the mounting bracket 100 on the moving wheels 510 during use, and reduces the possibility of the moving wheels 510 being crushed by the excessive weight of the mounting bracket 100 on the hoisting tower base and the construction personnel standing on the operating platform 400.

[0057] Based on the height of the tower flange, the operating platform 400 is erected on the support component 300 at a suitable height. The four corners of the operating platform 400 are then inserted into the corresponding snap-fit ​​grooves 320 to horizontally limit the operation platform 400. Construction personnel climb the reinforcing bar 610 to the operating platform 400 and operate the hoisting equipment 200 to hoist the tower lifting seat, so that the tower lifting seat is connected to the tower flange.
