Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a hoisting auxiliary hoisting device for assembled construction. Background Art

[0002] Prefabricated buildings refer to the prefabrication of various building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) in the factory, and then transporting these prefabricated components to the construction site, assembling and installing them through reliable connection methods to complete the overall construction of the building. Prefabricated building components in the factory significantly improve construction efficiency and shorten project construction period; the stable production environment in the factory ensures the manufacturing quality of components and reduces quality problems that may occur during on-site construction; accurate material calculations and factory production reduce resource and energy consumption, while reducing the generation of construction waste and wastewater, making it more environmentally friendly and energy-saving; flexible and diverse designs meet different construction needs, and standardized designs improve building safety; the need for on-site construction personnel is reduced, labor costs are reduced, and construction safety is improved.

[0003] At present, when assembling prefabricated building components, they usually need to be transported to the designated location through lifting equipment. However, due to the different spaces and shapes of different prefabricated building components during the assembly process, different lifting equipment is required. At present, prefabricated building components of different shapes can be lifted by replacing different lifting equipment.

[0004] However, it will take a certain amount of time to replace the slings on site, including dismantling the old slings, installing the new slings, debugging and testing, etc. This will extend the construction time and affect the progress of the project. Utility Model Content

[0005] The purpose of the utility model is to provide an auxiliary lifting device for lifting in assembled construction to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A lifting auxiliary hoist for assembled construction, including a connecting seat and an external controller, one end of the connecting seat is connected to the output end of an external boom through a steel cable, a first suspension rod is arranged below the connecting seat, the first suspension rod is fixedly connected to the connecting seat, a bidirectional screw rod is arranged inside the first suspension rod, the bidirectional screw rod is rotatably connected to the first suspension rod, one end of the first suspension rod is fixedly connected to a first motor, one end of the bidirectional screw rod is fixedly connected to the output end of the first motor, a slider is threadedly connected to the bidirectional screw rod, the slider is symmetrically arranged, the slider is slidably connected to the first suspension rod, a hook device is connected below the slider, and a lifting component with a rotating function is arranged above the first suspension rod.

[0008] When it is necessary to hoist prefabricated components, the required hoisting points can be used to determine whether the hoisting components need to work. When it is necessary to hoist some prefabricated components with fewer necessary hoisting points, such as walls, the first motor can be used to drive the bidirectional screw fixedly connected to its output end to rotate, thereby driving the slider to move along the direction of the bidirectional screw axis, and then hoisting it through the hook device under the slider. When it is necessary to hoist some prefabricated components with more necessary hoisting points, such as stairs, the hoisting components can be started to rotate the second hoisting rod to a suitable angle, and then used in conjunction with the hook assembly under the first hoisting rod, so as to achieve the purpose of hoisting prefabricated components of different shapes. By setting the hoisting components to rotate, not only the hoisting range of the hoist is expanded, but also the hoisting components can be retracted when not needed, thereby reducing some space restrictions on the hoist.

[0009] A further improvement of the technical solution of the utility model is that the lifting components include a lifting assembly, a control assembly, a locking assembly and a supporting assembly, the lifting assembly includes a second suspension rod, the second suspension rod is symmetrically arranged, a rotating screw is arranged inside the second suspension rod, the rotating screw is rotatably connected to the second suspension rod, a second motor is arranged at an end of the second suspension rod away from the connecting seat, the second motor is fixedly connected to the second suspension rod, the output end of the second motor is fixedly connected to the rotating screw, a slider is threadedly connected to the rotating screw, the slider is slidably connected to the second suspension rod, a hook device is connected below the slider, a slide plate is fixedly connected to one end of the second suspension rod close to the connecting seat, the slide plates are symmetrically arranged, a block is fixedly connected to the slide plate, the block is fan-shaped, a plurality of sliding grooves are provided on the connecting seat, the slide plates are slidably connected to the sliding grooves, and the slide plates and the block are used in conjunction with each other.

[0010] The above-mentioned technical scheme is adopted. In this scheme, when it is necessary to lift the prefabricated component by using the lifting component in cooperation with the hook device under the first suspension rod, the angle of the lifting component is adjusted by the control component, and then the lifting component is locked by the locking component, and the supporting component supports the lifting component. Then, the second motor is started by the external controller, and the second motor drives the rotating screw rod fixedly connected to it to rotate, thereby driving the slider to move along the axial direction of the rotating screw rod, and then the hook device located under the slider is used in cooperation with the hook device set under the first suspension rod to achieve the purpose of lifting the prefabricated component.

[0011] A further improvement of the technical solution of the utility model is that: the control component includes a driving gear, a third motor is fixedly connected in the connecting seat, a rotating shaft is fixedly connected to the output end of the third motor, the rotating shaft is fixedly connected to the driving gear, a support column is fixedly connected in the connecting seat, the support column is rotatably connected to the rotating shaft, a support shaft is rotatably connected on a symmetrically arranged skateboard, a driven gear is fixedly connected on the support shaft, the driving gear is meshed with the driven gear, a gear ring is arranged in the connecting seat, the gear ring is fixedly connected to the connecting seat, the driven gear is meshed with the gear ring, a plurality of connecting blocks are arranged above the driving gear, and the two ends of the connecting blocks are respectively fixedly connected to the skateboard on the side of the gear ring away from the first suspension rod.

[0012] The above technical solution is adopted. In this solution, when it is necessary to control the lifting assembly to rotate, the third motor will drive the driving gear fixedly connected to its output end to rotate through the rotating shaft. The rotation of the driving gear will drive the driven gear meshing with it to rotate. Because the driven gear is meshed with the ring gear, and the driven gear is rotatably connected to the skateboard through the support shaft, the driven gear will revolve around the driving gear in a circumferential direction while rotating on itself. At the same time, the stopper and the skateboard are used in combination to make the second suspension rod rotatably connected to the connecting seat. Therefore, when the driven gear rotates, the second suspension rod will rotate in a circumferential direction through the cooperation of the stopper and the skateboard. The maximum rotation angle of the second suspension rod is 90 degrees, thereby achieving the purpose of adjusting the angle.

[0013] A further improvement of the technical solution of the utility model is that: the locking assembly includes a pressure plate, which is slidably connected to the support column, a fixing plate is arranged between the slide plate on one side of the gear ring close to the first suspension rod, the fixing plates are symmetrically arranged, two ends of the fixing plates are respectively fixedly connected to the slide plate, a plurality of fixing holes are opened on the fixing plate in a circumferential direction, a spring is arranged under the pressure plate, one end of the spring is fixedly connected to the connecting seat, the other end of the spring is fixedly connected to the pressure plate, a fixing block is arranged on the side of the pressure plate away from the spring, the fixing block is used in conjunction with the fixing hole, a connecting plate is fixedly connected to the outer side of the pressure plate, a plurality of electric push rods are arranged in the connecting seat, the output end of the electric push rod is fixedly connected to the push plate, and the push plate is used in conjunction with the connecting plate.

[0014] The above-mentioned technical scheme is adopted. In this scheme, when the lifting component needs to rotate, the electric push rod is started, and the push plate located at the output end of the electric push rod will squeeze the connecting plate fixedly connected to the pressure plate, causing the pressure plate to move downward. At this time, the fixed block is separated from the fixing hole, and the third motor is started to drive the second lifting rod to rotate. When locking is required, the electric push rod is retracted, the spring will reset, thereby driving the pressure plate to reset, the connecting plate contacts the push plate, and the resetting of the pressure plate will drive the fixed block fixedly connected to it to cooperate with the fixing hole, thereby achieving the purpose of locking the lifting component.

[0015] A further improvement of the technical solution of the utility model is that the supporting assembly includes a shell and a connecting rod, the shell is fixedly connected to the connecting seat, a plurality of movable grooves are opened on the shell along the circumferential direction, a movable block is slidably connected in the movable groove, one end of the connecting rod is hinged to the second suspension rod, and the other end of the connecting rod is hinged to the movable block.

[0016] By adopting the above-mentioned technical solution, the purpose of supporting the second hanger can be achieved through the coordinated use of the moving block and the connecting rod. When the second hanger rotates, the second hanger will drive the moving block to rotate in the shell through the connecting rod, so that when the second hanger rotates, the connecting rod and the moving block can still support the second hanger when used in combination, thereby improving the stability of the structure.

[0017] A further improvement of the technical solution of the utility model is that a plurality of protection plates are fixedly connected between the symmetrically arranged slide plates, and the protection plates are in contact with the connection seats.

[0018] The above technical solution is adopted. In this solution, because there is generally a lot of dust in the air at construction sites, a protective plate can be provided to block the slide groove to prevent dust in the external air from entering the connecting seat and affecting the operation of the control component.

[0019] A further improvement of the technical solution of the utility model is that a counterweight is provided at one end of the first suspension rod away from the first motor, and the counterweight is fixedly connected to the first suspension rod.

[0020] By adopting the above technical solution, a counterweight block is provided at the end of the first suspension rod away from the first motor to ensure the stability of the device during operation, thereby avoiding accidents caused by unstable center of gravity.

[0021] A further improvement of the technical solution of the utility model is that: a plurality of heat dissipation holes are provided on the connecting seat, and the heat dissipation holes are located above the second suspension rod.

[0022] By adopting the above technical solution, heat dissipation holes are provided on the connecting seat to dissipate the heat generated by the third motor when it is working, thereby avoiding damage to the third motor caused by excessive temperature, thereby extending the service life of the third motor.

[0023] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0024] 1. The utility model provides a lifting auxiliary sling for assembled construction. When it is necessary to lift prefabricated components, it can be determined whether the lifting components need to work by judging the required lifting points. When it is necessary to lift some prefabricated components with fewer necessary lifting points such as walls, the first motor can be used to drive the bidirectional screw rod fixedly connected to its output end to rotate, thereby driving the slider to move along the direction of the bidirectional screw rod axis, and then hoisting it through the hook device under the slider. When it is necessary to lift some prefabricated components with more necessary lifting points such as stairs, the lifting components can be started at this time to make the second hoist rod rotate to a suitable angle, and then used in conjunction with the hook assembly under the first hoist rod, so as to achieve the purpose of lifting prefabricated components of different shapes. By arranging the lifting components to be rotatable, not only the lifting range of the sling is expanded, but also the lifting components can be retracted when not needed, thereby reducing some space restrictions on the sling.

[0025] 2. The utility model provides an auxiliary lifting device for assembled construction. When it is necessary to lift the prefabricated components by using the lifting components in conjunction with the hook equipment under the first suspension rod, the angle of the lifting assembly is adjusted by the control assembly, and then the lifting assembly is locked by the locking assembly, and the support assembly supports the lifting assembly. Then, the second motor is started by the external controller, and the second motor drives the rotating screw rod fixedly connected thereto to rotate, thereby driving the slider to move along the axial direction of the rotating screw rod, and then the hook equipment located under the slider is used in conjunction with the hook equipment arranged under the first suspension rod to complete the purpose of lifting the prefabricated components.

[0026] 3. The utility model provides an auxiliary lifting device for assembled construction. When the lifting component needs to be controlled to rotate, the third motor will drive the driving gear fixedly connected to its output end to rotate through the rotating shaft. The rotation of the driving gear will drive the driven gear meshing with it to rotate. Because the driven gear is meshed with the ring gear, and the driven gear is rotatably connected to the slide plate through the support shaft, the driven gear will revolve around the driving gear in the circumferential direction while rotating on its own. At the same time, the stopper and the slide plate can be used in combination to make the second suspension rod rotatably connected to the connecting seat. Therefore, when the driven gear rotates, the second suspension rod will rotate in the circumferential direction through the cooperation of the stopper and the slide plate, wherein the maximum rotation angle of the second suspension rod is 90 degrees, thereby achieving the purpose of adjusting the angle.

[0039] In this embodiment, when it is necessary to hoist prefabricated components, it can be determined whether the hoisting components need to work by judging the required hoisting points. When it is necessary to hoist some prefabricated components with fewer necessary hoisting points, such as walls, the first motor 4 can be used to drive the bidirectional screw rod 3 fixedly connected to its output end to rotate, thereby driving the slider 5 to move along the direction of the axis of the bidirectional screw rod 3, and then hoist it through the hook device under the slider 5. When it is necessary to hoist some prefabricated components with more necessary hoisting points, such as stairs, the hoisting components can be started at this time to rotate the second hoisting rod to a suitable angle, and then used in conjunction with the hook assembly under the first hoisting rod 2, so as to achieve the purpose of hoisting prefabricated components of different shapes. By setting the hoisting components to be rotatable, not only the hoisting range of the hoist is expanded, but also the hoisting components can be retracted when not needed, thereby reducing some space restrictions on the hoist.

[0040] like Figure 1 , Figure 3 As shown, in the present embodiment, preferably, the lifting components include a lifting assembly, a control assembly, a locking assembly and a supporting assembly, the lifting assembly includes a second suspension rod 6, the second suspension rod 6 is symmetrically arranged, a rotating screw rod 7 is arranged inside the second suspension rod 6, the rotating screw rod 7 is rotatably connected to the second suspension rod 6, a second motor 8 is arranged at one end of the second suspension rod 6 away from the connecting seat 1, the second motor 8 is fixedly connected to the second suspension rod 6, the output end of the second motor 8 is fixedly connected to the rotating screw rod 7, a slider 5 is threadedly connected to the rotating screw rod 7, the slider 5 is slidably connected to the second suspension rod 6, a hook device is connected below the slider 5, a slide plate 9 is fixedly connected to one end of the second suspension rod 6 close to the connecting seat 1, the slide plates 9 are symmetrically arranged, a block 10 is fixedly connected to the slide plate 9, the block 10 is fan-shaped, a plurality of slide grooves 11 are provided on the connecting seat 1, the slide plates 9 are slidably connected to the slide grooves 11, and the slide plates 9 and the block 10 are used in conjunction with each other.

[0041] When it is necessary to lift the prefabricated components by using the lifting components in conjunction with the hook equipment under the first hanger 2, the angle of the lifting components is adjusted through the control component, and then the lifting components are locked through the locking component, and the supporting component supports the lifting components. Then, the second motor 8 is started through the external controller, and the second motor 8 will drive the rotating screw 7 fixedly connected to it to rotate, thereby driving the slider 5 to move along the axial direction of the rotating screw 7, and then the hook equipment located under the slider 5 is used in conjunction with the hook equipment set under the first hanger 2 to achieve the purpose of lifting the prefabricated components.

[0042] like Figure 2 , Figure 4 , Figure 5As shown, preferably, the control component includes a driving gear 12, a third motor 13 is fixedly connected in the connecting seat 1, a rotating shaft 14 is fixedly connected to the output end of the third motor 13, the rotating shaft 14 is fixedly connected to the driving gear 12, a support column 15 is fixedly connected in the connecting seat 1, the support column 15 is rotatably connected to the rotating shaft 14, a support shaft 16 is rotatably connected to the skateboard 9 symmetrically arranged, a driven gear 17 is fixedly connected to the support shaft 16, the driving gear 12 is meshed with the driven gear 17, a gear ring 18 is arranged in the connecting seat 1, the gear ring 18 is fixedly connected to the connecting seat 1, the driven gear 17 is meshed with the gear ring 18, and a plurality of connecting blocks are arranged above the driving gear 12, and the two ends of the connecting blocks are respectively fixedly connected to the skateboard 9 on the side of the gear ring 18 away from the first suspension rod 2.

[0043] When it is necessary to control the lifting assembly to rotate, the third motor 13 will drive the driving gear 12 fixedly connected to its output end to rotate through the rotating shaft 14. The rotation of the driving gear 12 will drive the driven gear 17 meshing with it to rotate. Because the driven gear 17 is meshed with the ring gear 18, and the driven gear 17 is rotatably connected to the skateboard 9 through the support shaft 16, the driven gear 17 will revolve around the driving gear 12 in the circumferential direction while rotating on itself. At the same time, the stopper 10 and the skateboard 9 are used in conjunction to make the second suspension rod 6 rotatably connected to the connecting seat 1. Therefore, when the driven gear 17 rotates, the stopper 10 and the skateboard 9 will cooperate to make the second suspension rod 6 rotate in the circumferential direction. The maximum rotation angle of the second suspension rod 6 is 90 degrees, thereby achieving the purpose of adjusting the angle.

[0044] like Figure 5 , Figure 6 , Figure 7 As shown, preferably, the locking assembly includes a pressure plate 19, which is slidably connected to the support column 15, and a fixing plate 20 is arranged between the slide plate 9 on one side of the ring gear 18 close to the first suspension rod 2. The fixing plates 20 are symmetrically arranged, and both ends of the fixing plates 20 are respectively fixedly connected to the slide plate 9. A plurality of fixing holes 21 are opened on the fixing plate 20 along the circumferential direction, and a spring 22 is arranged below the pressure plate 19, one end of the spring 22 is fixedly connected to the connecting seat 1, and the other end of the spring 22 is fixedly connected to the pressure plate 19, and a fixing block 23 is arranged on the side of the pressure plate 19 away from the spring 22, and the fixing block 23 is used in conjunction with the fixing hole 21, and a connecting plate 24 is fixedly connected to the outer side of the pressure plate 19, and a plurality of electric push rods 25 are arranged in the connecting seat 1, and a push plate is fixedly connected to the output end of the electric push rod 25, and the push plate is used in conjunction with the connecting plate 24.

[0045] When the lifting component needs to be rotated, the electric push rod 25 is started, and the push plate located at the output end of the electric push rod 25 will squeeze the connecting plate 24 fixedly connected to the pressure plate 19, so that the pressure plate 19 moves downward. At this time, the fixed block 23 is separated from the fixing hole 21, and the third motor 13 is started to drive the second lifting rod 6 to rotate. When locking is required, the electric push rod 25 is retracted, the spring 22 is reset, thereby driving the pressure plate 19 to reset, the connecting plate 24 contacts the push plate, and the reset of the pressure plate 19 will drive the fixed block 23 fixedly connected to it to cooperate with the fixing hole 21, thereby achieving the purpose of locking the lifting component.

[0046] like Figure 1 , Figure 2 As shown, preferably, the support assembly includes a shell 26 and a connecting rod 27. The shell 26 is fixedly connected to the connecting seat 1. A plurality of movable grooves 28 are opened on the shell 26 along the circumferential direction. A movable block 29 is slidably connected in the movable groove 28. One end of the connecting rod 27 is hinged to the second suspension rod 6, and the other end of the connecting rod 27 is hinged to the movable block 29.

[0047] The purpose of supporting the second hanger 6 can be achieved by using the moving block 29 in conjunction with the connecting rod 27. When the second hanger 6 rotates, the second hanger 6 will drive the moving block 29 to rotate in the shell 26 through the connecting rod 27. Therefore, when the second hanger 6 rotates, the connecting rod 27 and the moving block 29 can still support the second hanger 6 when used in conjunction, thereby improving the stability of the structure.

[0048] like Figure 1 , Figure 5 As shown, preferably, a plurality of protective plates 30 are fixedly connected between the symmetrically arranged slide plates 9 , and the protective plates 30 are in contact with the connecting seat 1 .

[0049] Because there is generally a lot of dust in the air at construction sites, the protective plate 30 can be provided to block the slide groove 11 to prevent dust in the external air from entering the connecting seat 1 and affecting the operation of the control component.

[0050] like Figure 2 As shown, preferably, a counterweight 31 is provided at one end of the first suspension rod 2 away from the first motor 4 , and the counterweight 31 is fixedly connected to the first suspension rod 2 .

[0051] By providing a counterweight 31 at the end of the first suspension rod 2 away from the first motor 4, the stability of the device during operation can be ensured, thereby avoiding accidents caused by unstable center of gravity.

[0052] like Figure 2 As shown, preferably, a plurality of heat dissipation holes 32 are provided on the connecting seat 1 , and the heat dissipation holes 32 are located above the second suspension rod 6 .

[0053] The connection base 1 is provided with heat dissipation holes 32 to dissipate the heat generated by the third motor 13 when it is working, thereby preventing the third motor 13 from being damaged by excessive temperature, thereby extending the service life of the third motor 13.

[0054] The following is a detailed description of the working principle of this type of lifting auxiliary hoist for prefabricated construction.

[0055] like Figure 1-7As shown, when it is necessary to hoist prefabricated components, it can be determined whether the hoisting components need to work by judging the required hoisting points. When it is necessary to hoist some prefabricated components with fewer necessary hoisting points, such as walls, the first motor 4 can be used to drive the bidirectional screw rod 3 fixedly connected to its output end to rotate, thereby driving the slider 5 to move along the direction of the axis of the bidirectional screw rod 3, and then hoist it through the hook device under the slider 5. When it is necessary to hoist some prefabricated components with more necessary hoisting points, such as stairs, the hoisting components can be started at this time to rotate the second hoisting rod 2 to a suitable angle, and then used in conjunction with the hook assembly under the first hoisting rod 2, so as to achieve the purpose of hoisting prefabricated components of different shapes. By setting the hoisting components to be rotatable, not only the hoisting range of the hoist is expanded, but also the hoisting components can be retracted when not needed, thereby reducing some space restrictions on the hoist. When it is necessary to lift the prefabricated components by using the lifting components in conjunction with the hook equipment under the first hanger 2, the angle of the lifting components is adjusted through the control component, and then the lifting components are locked through the locking component, and the supporting component supports the lifting components. Then, the second motor 8 is started through the external controller, and the second motor 8 will drive the rotating screw 7 fixedly connected to it to rotate, thereby driving the slider 5 to move along the axial direction of the rotating screw 7, and then the hook equipment located under the slider 5 is used in conjunction with the hook equipment set under the first hanger 2 to achieve the purpose of lifting the prefabricated components. When the hoisting assembly needs to be controlled to rotate, the third motor 13 will drive the driving gear 12 fixedly connected to its output end to rotate through the rotating shaft 14. The rotation of the driving gear 12 will drive the driven gear 17 meshing with it to rotate. Because the driven gear 17 is meshed with the ring gear 18, and the driven gear 17 is rotatably connected to the slide plate 9 through the support shaft 16, the driven gear 17 will revolve around the driving gear 12 in the circumferential direction while rotating. At the same time, the stopper 10 and the slide plate 9 can be used in conjunction with the second suspension rod 6 to be rotatably connected with the connecting seat 1. Therefore, when the driven gear 17 rotates, the stopper 10 and the slide plate 9 will cooperate to make the second suspension rod 6 rotate in the circumferential direction, wherein the maximum angle of rotation of the second suspension rod 6 is 90 degrees, thereby achieving the purpose of adjusting the angle. Because there is generally a lot of dust in the air at the construction site, the protective plate 30 can block the chute 11 to prevent dust in the external air from entering the connecting seat 1 and affecting the operation of the control assembly.When the hoisting assembly needs to rotate, the electric push rod 25 is started, and the push plate at the output end of the electric push rod 25 squeezes the connecting plate 24 fixedly connected to the pressure plate 19, so that the pressure plate 19 moves downward, and the fixed block 23 is separated from the fixing hole 21, and the third motor 13 is started to drive the second suspension rod 6 to rotate. When locking is required, the electric push rod 25 is retracted, and the spring 22 is reset to drive the pressure plate 19 to reset, and the connecting plate 24 is in conflict with the push plate. The reset of the pressure plate 19 will drive the fixed block 23 fixedly connected thereto to cooperate with the fixing hole 21, thereby achieving the purpose of locking the hoisting assembly. The purpose of supporting the second suspension rod 6 can be achieved by the coordinated use of the moving block 29 and the connecting rod 27. When the second suspension rod 6 rotates, the second suspension rod 6 will drive the moving block 29 to rotate in the housing 26 through the connecting rod 27, so that when the second suspension rod 6 rotates, the connecting rod 27 and the moving block 29 can still support the second suspension rod 6 when used in combination, thereby improving the stability of the structure. The stability of the device during operation can be ensured by providing a counterweight block 31 at the end of the first suspension rod 2 away from the first motor 4, thereby avoiding accidents caused by unstable center of gravity. The heat dissipation holes 32 provided on the connecting seat 1 can dissipate the heat generated by the third motor 13 during operation, thereby avoiding damage to the third motor 13 due to excessive temperature, thereby extending the service life of the third motor 13.

[0056] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
