Description

Technical Field

[0001] The invention relates to the technical field of beam moving machine hoisting devices, in particular to an aerial posture-adjustable hoisting hoisting device for a beam moving machine. Background Art

[0002] A beam moving machine is a device for moving beams. During use, it can transport beams quickly and efficiently, greatly reducing construction time and labor costs and improving the construction progress of the entire project. The sling is an important part of the beam moving machine. When in use, it docks with the preset lifting ears on the workpiece to ensure that the workpiece is transported stably. During the use of the sling, stability is of paramount importance. If the sling is not stable enough and cannot adjust its aerial posture according to actual conditions, the workpiece may fall due to wind force, which will not only cause damage to the workpiece but also cause accidents in serious cases. In order to improve the stability of the sling, prior art 1 (Chinese patent application with application number 201721521442.6 and application date 2017-11-15) is a fixed beam sling. When working, it first changes the lifting mode to increase stability; second, it adds an anti-unhooking device. Through the above Improvements are made to achieve smooth and safe lifting of nuclear containers. Existing technology 2 (Chinese patent application with application number 201320032140.8 and application date 2013-01-22) is a wind turbine and cabin assembly hoist. When working, it connects the cabin to the cabin hoisting parts, and at the same time connects the generator hoisting wire rope sleeve to the hoisting shafts on both sides of the generator. It is lifted by the main lifting belt. Since there are at least three lifting points, it remains stable as a whole; the entire device is not easy to flip, deflect, or rotate, and has strong stability. Existing technology 3 (Chinese patent application with application number 201922375784.7 and application date 2019-12-25) is a high-stability combined hoist. When working, it is equipped with a secondary structure and restrained by connecting shafts and hooks to reduce the swing amplitude during the lifting process. The combined hoist has higher stability, reduces safety hazards, and improves work efficiency.

[0003] However, during long-term use, especially when used at the seaside, the air humidity and salt content at the seaside are high, which makes it very easy to corrode the chain. Over time, the corrosion of the chain is accelerated, and there are other dust residues and bird droppings residues. The device in the above application does not have the function of auxiliary cleaning of the chain during use, and the dust may contain various chemical components (such as sulfides, nitrides, etc.). When these dusts adhere to the surface of the chain and combine with moisture in the air, an electrolyte solution is formed, which triggers an electrochemical reaction and accelerates the corrosion process of the chain. At the same time, the hard nodules formed by bird droppings will not only accelerate corrosion, but also increase wear, shorten the service life of the chain, and also increase safety hazards. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: a novel structural design is adopted, in which a movable equipment box is provided, so that the traction chain can clamp workpieces of different sizes. When the aerial posture needs to be adjusted, the driving motor on the surface of the equipment box on one side can be started to change the angle of the workpiece, so that the workpiece can cope with different situations in the air and improve stability. During the movement of the equipment box, the cleaning pipe will move in the vertical direction and rotate on the side of the docking plate, which can effectively clean the dust, impurities and bird droppings on the surface of the traction chain. At the same time, the air bag will be intermittently squeezed, so that the nozzle can clean the dust on the surface of the traction chain, so that the traction chain can be kept clean, thereby extending the service life of the traction chain. The specific contents are as follows:

[0016] The beam moving machine uses an aerial attitude-adjustable lifting sling. During use, when it is necessary to clamp the workpiece, the motor can be started. The motor drives the threaded rod to rotate through the bevel gear, and then the equipment boxes move closer or farther away from each other, making it easier for the traction chain to clamp workpieces of different sizes. When it is necessary to adjust the aerial attitude, the drive motor on the surface of the equipment box on one side can be started to change the angle of the workpiece, making it easier for the workpiece to cope with different situations in the air and improving stability.

[0017] The beam moving machine uses an aerial attitude-adjustable lifting sling. During the movement of the equipment box, the push block on the upper surface of the connecting rod will intermittently push the outer plate on the surface of the cleaning tube, so that the cleaning tube can perform reciprocating linear motion in the vertical direction under the action of thrust, limit plate and auxiliary spring. At this time, the cleaning tube can clean impurities and dust on the surface of the traction chain, prevent the traction chain from being corroded, and extend the service life of the traction chain.

[0018] Furthermore, during the movement of the cleaning tube, the force-bearing block will be driven to move synchronously, and then the force-bearing block will be pushed intermittently by the pressure rod. At this time, the force-bearing block, the cleaning tube and the slider will swing back and forth on the side of the docking plate under the action of thrust, return spring and guide rod. At this time, the cleaning tube not only performs reciprocating linear motion in the vertical direction, but is also in a reciprocating rotational swinging state, which can better clean the traction chain and improve the working efficiency of the cleaning tube.

[0019] The beam moving machine uses an aerial posture-adjustable lifting sling. During the movement of the equipment box, the airbag and the movable plate will be driven to move synchronously, and the secondary magnet on the upper surface of the movable plate will intermittently approach the main magnet on the lower surface of the connecting rod. At this time, the movable plate will make reciprocating linear motion in the vertical direction under the action of the mutual magnetic force and the elastic force of the connecting spring, and the movable plate will intermittently squeeze the airbag, causing the airbag to intermittently spray air through the outlet pipe and nozzle, to assist in cleaning the traction chain and improve the cleaning effect.

[0020] Furthermore, when the airbag is not squeezed, it will expand again. At this time, the airbag takes in air through the air intake pipe. During the process of airbag ejection and intake, the one-way valve makes the airflow direction from the air intake pipe to the nozzle, ensuring stability.

[0021] Furthermore, when the movable plate moves up and down, the connecting rod drives the nozzle to swing, thereby expanding the working range of the nozzle. When the nozzle swings upward, the pull rope on the surface of the auxiliary frame will stretch the elastic bag. At this time, the opening of the air outlet position on the surface of the nozzle becomes smaller. Then, under the condition of the same air output volume, the nozzle can now clean dust at a farther position, and the air output speed is faster and the cleaning effect is better.

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] The present invention provides the following technical solution: an aerial posture-adjustable lifting sling for a beam moving machine.

[0038] Embodiment 1: By setting a movable device box 6, workpieces of different sizes can be clamped. At the same time, the driving machine 7 on the surface of the device box 6 can change the length of the unilateral traction chain 8, thereby changing the aerial posture of the workpiece, so that the workpiece can cope with different situations and improve stability, such as Figure 1-Figure 3 As shown, it includes a working plate 1, an equipment box 6 is movably provided inside the working plate 1, and a traction chain 8 is movably provided inside the equipment box 6, and a driving machine 7 is bolted to the surface of the equipment box 6; a motor 2 is fixedly connected to the upper surface of the working plate 1, and a threaded rod 3 is rotatably provided inside the working plate 1, and a bevel gear 5 is fixedly connected to the surface of the threaded rod 3 and the output end of the motor 2.

[0039] The upper surface of the equipment box 6 is convex, and a limit bar 4 is fixedly connected to the inner wall of the working plate 1, and the limit bar 4 runs through the interior of the equipment box 6, and the equipment box 6 is threadedly connected to the threaded rod 3, and the traction chain 8 is arranged at the output end of the driving machine 7.

[0040] During use, when it is necessary to clamp the workpiece, the motor 2 can be started. The motor 2 drives the threaded rod 3 to rotate through the bevel gear 5, and then the equipment box 6 is moved closer or farther away from each other under the action of the threaded rod 3 and the limit bar 4, so that the traction chain 8 can clamp workpieces of different sizes. When it is necessary to adjust the aerial posture of the workpiece, the drive motor 7 on the surface of the equipment box 6 on one side can be started to release or reel in the traction chain 8, so that the height of the single-sided traction chain 8 changes, and then the workpiece changes its angle, which makes it easier for the workpiece to cope with different situations in the air and improves stability.

[0041] Embodiment 2: The use of the beam moving machine will be affected by external environmental factors according to the different construction working environments. In particular, when working in coastal areas, the lifting chain used in such an environment will have a water film condensed on its surface due to the high humidity of the seaside air. In addition, the seaside air has a high salt content, and the main components are sodium chloride, magnesium chloride, and calcium chloride. These salt particles will adhere to the surface of the lifting chain with the flow of air. When there is water on the surface of the lifting chain, the salt will dissolve to form an electrolyte solution, causing electrochemical corrosion, which can destroy the oxide film on the metal surface, expose the metal to a corrosive environment, and accelerate the corrosion process. In order to overcome these effects on the traction chain 8, a cleaning pipe 12 is provided, which can be moved in the vertical direction, and the traction chain 8 can be cleaned. Figure 4-Figure 8As shown, the lower surface of the equipment box 6 is fixedly connected to the limiting plate 11, and the surface of the limiting plate 11 is sleeved with a docking plate 13, and the lower surface of the equipment box 6 is connected to the cleaning tube 12 through a reciprocating structure; the reciprocating structure includes a slider 15 fixedly connected to the surface of the cleaning tube 12, and the end of the slider 15 is slidably arranged inside the docking plate 13, and the surface of the cleaning tube 12 is fixedly connected to an outer plate 16, and the outer plates 16 are symmetrically distributed on both sides of the cleaning tube 12.

[0042] The lower surface of the equipment box 6 is fixedly connected to a connecting rod 9, and the front view of the connecting rod 9 is an inverted "U" shape, and the upper surface of the connecting rod 9 is fixedly connected to a push block 10, and the push blocks 10 are evenly spaced on the upper surface of the connecting rod 9, and the surface of the push block 10 is an arc structure. The upper surface of the docking plate 13 is fixedly connected to an auxiliary spring 17 that plays an elastic reset role, and the other side of the auxiliary spring 17 is fixedly connected to the bottom of the equipment box 6, and a damping rod 19 is arranged between the docking plate 13 and the equipment box 6.

[0043] During the movement of the equipment box 6, the push block 10 on the upper surface of the connecting rod 9 will intermittently push the outer plate 16 on the surface of the cleaning tube 12. When the outer plate 16 is pushed, the cleaning tube 12 rises. At this time, the cleaning tube 12 drives the docking plate 13 to rise through the slider 15 and the guide rod 14. At this time, the auxiliary spring 17 is squeezed, and when the outer plate 16 is not pushed by the push block 10, the cleaning tube 12 descends in the vertical direction through the slider 15, the guide rod 14, the docking plate 13 under the action of the auxiliary spring 17, the limit plate 11 and its own gravity (the damping rod 19 improves stability). Repeat the above process, and the cleaning tube 12 performs reciprocating linear motion in the vertical direction. At this time, the cleaning tube 12 can clean impurities and dust on the surface of the traction chain 8, prevent the traction chain 8 from being corroded, and extend the service life of the traction chain 8.

[0044] Embodiment 3: Different from embodiment 2, the force block 21 and the pressure rod 20 are provided to make the cleaning tube 12 rotate, thereby improving the cleaning effect. Figure 7-Figure 8 As shown, the reciprocating structure also includes a pressure rod 20 fixedly connected to the surface of the limit plate 11, a force block 21 is fixedly connected to the surface of the cleaning tube 12, and the surface of the force block 21 is inclined, and the surface of the force block 21 is fitted with the end of the pressure rod 20, a guide rod 14 is fixedly connected to the inner wall of the docking plate 13, and a slider 15 is sleeved on the surface of the guide rod 14, and a reset spring 22 that plays an elastic reset role is fixedly connected to the surface of the slider 15, and the other side of the reset spring 22 is fixedly connected to the inner wall of the docking plate 13.

[0045] When the cleaning tube 12 rises, the force block 21 will be squeezed by the pressure rod 20. At this time, the force block 21 will drive the cleaning tube 12 and the slider 15 to slide (the guide rod 14 makes the movement of the slider 15 and the cleaning tube 12 more stable). At this time, the return spring 22 is squeezed, and when the cleaning tube 12 descends, the force block 21 loses the pressure of the pressure rod 20. At this time, the cleaning tube 12 and the slider 15 return to their original positions under the action of the return spring 22. The above process is repeated. The cleaning tube 12 will not only move in the vertical direction, but also rotate, thereby optimizing the cleaning effect.

[0046] Embodiment 4: Different from embodiment 3, the air bag 26 and the nozzle 30 are provided to assist in cleaning the surface of the traction chain 8, such as Figures 9-11 As shown, an air bag 26 is bonded to the lower surface of the equipment box 6, and an air outlet pipe 28 is fixedly connected to the surface of the air bag 26, and a nozzle 30 is fixedly connected to the end of the air outlet pipe 28. The lower surface of the connecting rod 9 is fixedly connected to the main magnet 25, and the main magnets 25 are evenly spaced on the lower surface of the connecting rod 9. The lower surface of the equipment box 6 is fixedly connected to a column 23, and the end of the column 23 is convex, and a movable plate 24 is sleeved on the surface of the column 23.

[0047] The upper surface of the movable plate 24 is fixedly connected to a secondary magnet 32, and the magnetic poles of the upper surface of the secondary magnet 32 ​​are opposite to the magnetic poles of the lower surface of the main magnet 25, and the lower surface of the movable plate 24 is fixedly connected to a connecting spring 31, and the other side of the connecting spring 31 is fixedly connected to the bottom of the movable plate 24, the surface of the airbag 26 is fixedly connected to the air inlet pipe 27, and the surfaces of the air inlet pipe 27 and the air outlet pipe 28 are both fixedly connected to a one-way valve 29.

[0048] During the movement of the equipment box 6, the airbag 26 and the movable plate 24 will be driven to move synchronously, and then the secondary magnet 32 ​​on the upper surface of the movable plate 24 will intermittently approach the main magnet 25 on the lower surface of the connecting rod 9. When the secondary magnet 32 ​​approaches the main magnet 25, the movable plate 24 rises under the action of the mutual magnetic force. At this time, the connecting spring 31 is stretched (the column 23 makes the movable plate 24 move only in the vertical direction). When the secondary magnet 32 ​​moves away from the main magnet 25, the movable plate 24 falls under the action of the connecting spring 31, and the above process is repeated. During the cleaning process, the movable plate 24 makes a reciprocating linear motion in the vertical direction, and then the movable plate 24 will intermittently squeeze the airbag 26, so that the airbag 26 intermittently sprays air through the air outlet pipe 28 and the nozzle 30, thereby assisting in cleaning the traction chain 8 and improving the cleaning effect. When the airbag 26 is not squeezed, the airbag 26 will expand again. At this time, the airbag 26 takes in air through the air inlet pipe 27. During the process of the airbag 26 spraying and taking in air, the one-way valve 29 makes the airflow flow direction from the air inlet pipe 27 to the nozzle 30, thereby ensuring stability.

[0049] Example 5: The nozzle 30 can be swung to blow air by the connecting rod 33, and the elastic bag 35 can be used to change the size of the nozzle 30 outlet position, so that air can be blown at a farther distance, such as Figure 12 and Figure 13 As shown, the side of the movable plate 24 of the nozzle 30 is fixedly connected with an inverted "L"-shaped connecting rod 33, and the end of the connecting rod 33 is sleeved on the surface of the air outlet pipe 28, and the middle section of the air outlet pipe 28 is made of flexible material, the surface of the nozzle 30 is fixedly connected with an elastic bag 35, the lower surface of the equipment box 6 is fixedly connected with an auxiliary frame 34 with a "U"-shaped structure, and the surface of the auxiliary frame 34 is fixedly connected with a pull rope 36, and the middle section of the pull rope 36 is located inside the elastic bag 35, and the left side of the pull rope 36 is "Y"-shaped.

[0050] When the movable plate 24 moves up and down, the nozzle 30 is driven to swing by the connecting rod 33, thereby expanding the working range of the nozzle 30. When the nozzle 30 swings upward, the pull rope 36 on the surface of the auxiliary frame 34 will stretch the elastic bag 35. At this time, the opening of the air outlet position on the surface of the nozzle 30 becomes smaller. Then, under the condition of the same air output volume, the nozzle 30 can now clean dust at a farther position, and the air output speed is faster and the cleaning effect is better. When the nozzle 30 swings downward, the elastic bag 35 loses the tension of the pull rope 36, and the elastic bag 35 is reset to facilitate the next use.

[0051] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
