Abstract
Description
Technical Field
[0001] This utility model relates to the field of bracket dismantling technology, specifically an automatic bracket dismantling device for tower construction machines. Background Technology
[0002] Multiple hangers are spliced on the outer wall of the tower, with the uppermost hanger suspended in the lifting mechanism on the tower-building machine. After being raised and lowered by the lifting mechanism, it is attached to the tower wall. A walkway is installed on the inner side of the hanger to facilitate the construction of the outer wall of the tower. After the tower is built, the hanger slides out of the lifting mechanism and is disassembled. The aerial disassembly of the hanger enables the tower-building machine to successfully complete the external expansion construction of the main structure and provides convenience for subsequent construction.
[0003] However, in the utility model of an automatic bracket disassembly device with patent application number CN202420095320.9, the bracket is disassembled by sliding on the I-shaped extension frame using hydraulic pressure. Although this achieves the effect of automatic bracket disassembly without manual operation, the bracket has two sliding points. When sliding out, one of the sliding points will disengage from the I-shaped extension frame first, and the lower bracket is prone to imbalance and tilting. In subsequent sliding, the sliding point that has not slid out is prone to imbalance, affecting the safety when disassembling and falling. Utility Model Content
[0004] This utility model provides an automatic dismantling device for the hanging frame of a tower construction machine, which overcomes the shortcomings described in the background art.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] An automatic dismantling device for the hanging frame of a tower construction machine includes a connector, a hanging frame, a sunshade, and a connecting plate. The hanging frame is arranged in two rows, parallel to each other and vertically connected by the connecting plate. The hanging frame is extended by the connector, and a sunshade is provided on one side of the hanging frame. The uppermost end of the hanging frame is provided with a suspension mechanism, and the suspension mechanism is suspended on the I-shaped extension frame. The hanging frame is engaged with the lower end of the suspension mechanism.
[0007] The suspension mechanism includes a fixed plate, an I-shaped strip, and a disassembly structure. The fixed plate is fixed to both sides of the I-shaped extension frame by bolts. The disassembly structure is located at the upper end of the I-shaped strip and is engaged with both ends of the fixed plate. The disassembly structure is connected to an external wire, and the opening and closing of the disassembly structure is controlled by the power of the wire, so that the disassembly structure is disengaged from the engagement of the fixed plate.
[0008] A preferred technical solution: The I-shaped strip is provided with a fixed block, a hydraulic device, an open block and a load-bearing block. The load-bearing block is spirally fixed on the left and right sides of the open block. The hydraulic device is located on the outside of the fixed block. The fixed block is spirally fixed inside the fixed plate. The hydraulic device is connected to an external wire and is driven by an electrical signal to hydraulically extend and retract, and the output end of the hydraulic device enters the load-bearing block for blocking.
[0009] A preferred technical solution: The load-bearing block is provided with a cylinder, an elastic block and a convex block. The outer side of the cylinder is provided with an elastic block and is elastically connected to the middle of the convex block through the elastic block. The convex block rotates threadedly on both sides of the opening block and brings the cylinder close to the output end of the hydraulic device.
[0010] A preferred technical solution: The inner side of the cylinder is provided with ball bearings, which slide in conjunction with the ball bearings when the output end of the hydraulic device extends or retracts inward.
[0011] A preferred technical solution: The elastic block is made of rubber. When the output end of the hydraulic device enters the cylinder, the convex block moves toward the hydraulic device by rotating the load-bearing block. The elastic block elastically presses against the outer shell of the hydraulic device, and the output end of the hydraulic device is fully inserted into the cylinder.
[0012] Compared with existing technologies, this technical solution has the following advantages:
[0013] In this utility model, when disassembling the suspension mechanism, the hydraulic device is controlled by an external wire to extend and retract hydraulically. After the output end of the hydraulic device extends and retracts inward, it detaches from the support of the load-bearing block. Under the weight of the bracket, the open block falls off, preventing the open block from sliding on the I-shaped extension frame and causing one end to fall first and tilt. This avoids the open block tilting and causing friction between the open block and the I-shaped extension frame, achieving fast and accurate disassembly and preventing instability caused by sliding disassembly from affecting disassembly safety.
[0014] In this invention, when the open block is suspended at the output end of the hydraulic device, the hydraulic device slides against the ball bearings inside the cylinder. Under the rotation of the load-bearing block, the cylinder presses against the outer shell of the hydraulic device under the elastic force of the elastic block, so that the exposed output end of the hydraulic device is completely inserted into the cylinder. The interior of the hydraulic device serves as a fixed support point, and the exposed output end of the hydraulic device serves as a load-bearing point. The support length and load-bearing length on both sides of the output end of the hydraulic device are the same, preventing imbalance caused by different lever distances on both sides of the output end of the hydraulic device, avoiding the lever prying effect, and making the load-bearing block stably suspended at the output end of the hydraulic device.

Detailed Implementation
[0021] like Figures 1 to 4 As shown, this utility model proposes an automatic dismantling device for the hanging frame of a tower construction machine, including a connector 1, a hanging frame 2, a sunshade 4, and a connecting plate 5. The hanging frame 2 is provided in two rows, which are parallel to each other and vertically connected by the connecting plate 5. The hanging frame 2 is connected and extended by the connector 1, and a sunshade 4 is provided on one side of the hanging frame 2. The uppermost end of the hanging frame 2 is provided with a suspension mechanism 3, and the suspension mechanism 3 is suspended on the I-shaped extension frame. The hanging frame 2 is engaged with the lower end of the suspension mechanism 3.
[0022] The suspension mechanism 3 is provided with a fixing plate 31, an I-shaped strip 32 and a disassembly structure 33. The fixing plate 31 is fixed to both sides of the I-shaped extension frame by bolts. The disassembly structure 33 is located at the upper end of the I-shaped strip 32. The disassembly structure 33 is engaged with both ends of the fixing plate 31. The disassembly structure 33 is connected to an external wire, and the opening and closing of the disassembly structure 33 is controlled by the power of the wire, so that the disassembly structure 33 is disengaged from the engagement of the fixing plate 31.
[0023] Furthermore, the I-shaped strip 32 has holes, the bracket 2 is inserted into the I-shaped strip 32, and is fixed to the I-shaped strip 32 by bolts passing through the holes.
[0024] The I-shaped strip 32 is provided with a fixed block 331, a hydraulic device 332, an opening block 333, and a load-bearing block 334. The load-bearing block 334 is spirally fixed on the left and right sides of the opening block 333. The hydraulic device 332 is located outside the fixed block 331. The fixed block 331 is spirally fixed inside the fixed plate 31. The hydraulic device 332 is connected to an external wire, and the hydraulic device 332 is hydraulically extended and retracted through an electrical signal, so that the output end of the hydraulic device 332 enters the load-bearing block 334 for blocking.
[0025] Furthermore, the fixing plates 31 are symmetrically distributed on both sides of the I-shaped extension frame, and the fixing plates 31 correspond to the load-bearing blocks 334 on both sides of the upper end of the opening block 333. When the fixing plates 31 are fixed on the I-shaped extension frame, the fixing plates 31 protrude from the bottom of the I-shaped extension frame, so that when the load-bearing blocks 334 fall down, the inner side of the load-bearing blocks 334 will not touch the I-shaped extension frame, thus preventing the load-bearing blocks 334 from being blocked when they fall.
[0026] The load-bearing block 334 is provided with a cylinder 41, an elastic block 42 and a convex block 43. The cylinder 41 is provided with an elastic block 42 on its outer side and is elastically connected to the middle of the convex block 43 through the elastic block 42. The convex block 43 rotates threadedly on both sides of the opening block 333 and brings the cylinder 41 close to the output end of the hydraulic device 332.
[0027] Furthermore, when the cylinder 41 is close to the output end of the hydraulic unit 332, the weight of the lower end of the opening block 333 is borne by the convex block 43 in the cylinder 41 and transferred to the fixed block 331 through the output end of the hydraulic unit 332. Thus, the fixed plate 31 is fixed to both sides of the I-shaped extension frame to bear the weight of the lower end of the opening block 333. The cylinder 41 being close to the output end of the hydraulic unit 332 ensures that the inside of the hydraulic unit 332 and the cylinder 41 are symmetrically stressed through the output end of the hydraulic unit 332, and makes the stress point relatively close to the midpoint of the output end of the hydraulic unit 332, preventing the weight of the cylinder 41 at the output end of the hydraulic unit 332 from having a long distance.
[0028] Furthermore, the inner side of the cylinder 41 is provided with ball bearings, which slide in conjunction with the ball bearings when the output end of the hydraulic device 332 extends or retracts inward.
[0029] The elastic block 42 is made of rubber. When the output end of the hydraulic device 332 enters the cylinder 41, the convex block 43 moves toward the hydraulic device 332 by rotating the load-bearing block 334. The elastic block 42 elastically presses against the outer shell of the hydraulic device 332, and the output end of the hydraulic device 332 is completely inserted into the cylinder 41.
[0030] In this invention, the hanger 2 is connected via the connecting plate 5 and is arranged around the bottom of the I-shaped extension frame. The hanger 2 is fixed to the lower end of the suspension mechanism 3. The disassembly structure 33 at the upper end of the I-shaped strip 32 is fixed to both sides of the I-shaped extension frame via the fixing plate 31. Thus, the hanger 2 is suspended on the I-shaped extension frame via the suspension mechanism 3. During suspension, the I-shaped extension frame is inside the opening block 333, and the load-bearing block 334 is rotated so that the cylinder 41 in the load-bearing block 334 engages with the output end of the hydraulic device 332. It is then fixed to both sides of the I-shaped extension frame by the two fixing plates 31, thus achieving the opening of the fixing plates 31. The supporting and load-bearing effect of the opening block 333 is such that when the suspension mechanism 3 is disassembled, the hydraulic device 332 is controlled by an external wire to extend and retract hydraulically, so that the output end of the hydraulic device 332 extends and retracts inward and disengages from the support block 334. Under the gravity of the bracket 2, the opening block 333 falls, achieving a quick disassembly effect. This prevents the opening block 333 from sliding on the I-shaped extension frame, causing one end to fall first and tilting. It also avoids the opening block 333 tilting and causing friction between the opening block 333 and the I-shaped extension frame, achieving quick and accurate disassembly and preventing instability caused by sliding disassembly from affecting disassembly safety.
[0031] In this invention, when the opening block 333 is suspended at the output end of the hydraulic device 332, the hydraulic device 332 slides with the ball bearings inside the cylinder 41. Under the rotation of the load-bearing block 334, the cylinder 41 presses against the outer shell of the hydraulic device 332 under the elastic force of the elastic block 42, so that the exposed output end of the hydraulic device 332 is completely inserted into the cylinder 41. The interior of the hydraulic device 332 serves as a fixed support point, and the exposed output end of the hydraulic device 332 serves as a load-bearing point. The support length and load-bearing length on the left and right sides of the output end of the hydraulic device 332 are the same, preventing the lever distance on both sides of the output end of the hydraulic device 332 from being different and causing imbalance, avoiding the lever prying effect, so that the load-bearing block 334 is stably suspended at the output end of the hydraulic device 332.
[0032] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
