DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] like Figure 1 As shown, the embodiment of the present utility model provides a multi-point hoisting balancing device, including a frame structure 1, a pulley system 2 and a balance adjustment system 3. The frame structure 1 includes a first crossbeam 101 and a second crossbeam 102 arranged opposite to each other in an upper and lower direction. The pulley system 2 is fixedly connected between the first crossbeam 101 and the second crossbeam 102, and the pulley system 2 is connected to the balance adjustment system 3.

[0032] The balance adjustment system 3 includes a signal transmitter 301 and a controller 302 . The signal transmitter 301 communicates wirelessly with the controller 302 , and the controller 302 is connected to the winch of the pulley system 2 .

[0033] In this embodiment, if Figure 1As shown, the frame structure 1 includes a first crossbeam 101 and a second crossbeam 102, which are arranged in a rectangular configuration. The upper flange of the first crossbeam 101 is fixed with multiple lifting rings 103 for use with a crane. The lower flange of the second crossbeam 102 is provided with multiple lifting holes for the lifting rings 103. Furthermore, the lower flange of the second crossbeam 102 is fixed with multiple locking latches 105 for use in securing components.

[0034] Preferably, two lifting rings 103 are preset on the upper flange of the first crossbeam 101, and the two lifting rings 103 are arranged at intervals, which can effectively distribute the lifting force and maintain stability during the lifting process; three lifting holes are preset on the lower flange of the second crossbeam 102, and four locking buckles 105 are fixed on its lower flange, and the lifting holes and locking buckles 105 are arranged at intervals in sequence.

[0035] Preferably, a plurality of stiffening ribs 104 are fixedly provided in the middle of both sides of the web of the first beam 101 for use in clamping and hoisting by the hanging basket, which can also improve the stiffness of the clamping area and avoid deformation of the beam caused by direct clamping on the upper flange of the beam; stiffening ribs 104 are also fixedly provided on the upper part of the second beam lock, which can effectively improve the stability and torsional resistance of the beam.

[0036] In some embodiments, the lifting ring 103, the locking buckle 105 and the stiffening rib 104 are fixed by welding.

[0037] In some embodiments, different lifting solutions can be selected when the lifting requirements are different. The first crossbeam 101 can be used for lifting by a crane using a steel cable or by clamping a basket, and the second crossbeam 102 can be used for locking or steel cable fixation.

[0038] In some embodiments, when the size of the frame structure 1 cannot meet the requirements of hoisting construction, the size of the first beam 101 and the second beam 102 and the number of pulley devices can be changed, and the position of the lifting hole opening and the lock position of the lower flange of the second beam can be changed to meet the requirements of hoisting construction. It can be flexibly set according to actual conditions and is not specifically limited in this embodiment.

[0039] In the embodiment, the pulley system 2 is fixedly connected between the first cross beam 101 and the second cross beam 102, and includes the first pulley device 203 and the second pulley device 204 which are arranged at intervals on the lower flange of the first cross beam 101, the third pulley device 205, the fourth pulley device 206 and the fifth pulley device 207 which are arranged at intervals on the upper flange of the second cross beam 102, the first winch 201 and the second winch 202 which are fixedly arranged at the two ends of the lower flange of the first cross beam 101, and the first winch 201, the third pulley device 205, the first pulley device 203, the fourth pulley device 206, the second pulley device 204, the fifth pulley device 207 and the second winch 202 which are sequentially connected by the rope 208. The rope 208 is adjusted by being wound and unwound by the first winch 201 and the second winch 202, so as to adjust the pulley system 2, and further to realize the linear change of the inclination angle of the hoisting component.

[0040] The pulley system 2 includes five pulley devices, each of which is composed of two pulleys to improve stability. Each pulley device is fixed on the cross beam by welding.

[0041] In some embodiments, the rope 208 is a steel cable.

[0042] The first winch 201 and the second winch 202 wind or release the rope 208 at the two ends of the first cross beam 101, so as to realize the lifting of the two ends of the second cross beam 102. The first winch 201 and the second winch 202 are the same in structure, and include a motor and a drum fixedly connected with the motor. The motor provides a power source to drive the drum to work, and the drum is used to realize the winding and unwinding of the rope.

[0043] In the embodiment, as shown in Figure 5 The balance adjustment system 3 includes a signal transmitter 301 and a controller 302. The signal transmitter 301 is in wireless communication with the controller 302. The controller 302 is fixedly arranged in the interior of the first cross beam 101. The two ends of the controller 302 are connected with the first winch 201 and the second winch 202 by wires, specifically, are connected with the first motor and the second motor in the interiors of the first winch 201 and the second winch 202. The winding and unwinding of the rope is realized by the motor driving the drum, so as to realize the adjustment of the level or inclination angle of the second cross beam, and finally realize the pose adjustment of the hoisting component.

[0044] In some embodiments, the signal transmitter 301 can be a manual transmission device such as a remote controller, which can be manually operated by a construction worker at the construction site to transmit instructions to the controller 302, and the controller 302 decodes the instructions and controls the corresponding hoist according to the decoding result, which can achieve rough adjustment of the pose of the hoisted member (such as a steel box girder or a prefabricated member). The existing equipment can be used to achieve the manual transmission device, such as the Dijun multi-channel remote controller, and the DH-Z3F4P45XH, DH-Z6F1P8XH, DH-Z2M4F1P4XH, etc. can be selected, and the corresponding equipment can be customized according to the needs. The controller can be achieved by using the existing equipment, such as JMDM-WXMT02. The selection of the above-mentioned equipment can be flexibly selected according to the actual situation, and the present embodiment is not limited.

[0045] In other embodiments, the signal transmitter 301 can be an automatic transmission device, i.e. a computer, which transmits instructions to the controller 302 according to the programmed program, and the controller 302 decodes the instructions and controls the corresponding hoist according to the decoding result, which can achieve accurate adjustment of the pose of the hoisted member, completely meet the pre-designed inclination angle of the hoisted member, and meet the construction design requirements.

[0046] Specifically, as shown in Figure 1 In a single multi-point hoisting balance device, the controller 302 controls the first motor and the second motor connected thereto. The controller 302 is connected to the first motor through the first relay and connected to the second motor through the second relay. The controller 302 indirectly controls the start and stop of the motor through the switch of the relay, and controls the number of rotations of the motor by controlling the closing and opening time of the relay, that is, the controller 302 sends a signal to the relay, and the relay controls the power supply of the motor to be turned on and off, thereby realizing the control of the motor.

[0047] Further, the controller 302 is connected to the first relay and the second relay through the output port, respectively, and can send an electrical signal to the relay. The contacts of the first relay are connected to the power supply line of the first motor, and the contacts of the second relay are connected to the power supply line of the second motor. When the relay contacts are closed, the power supply is connected to the motor, and the motor starts to operate. When the relay contacts are opened, the power supply is disconnected, and the motor stops operating. After the controller 302 receives the instructions, the instructions are decoded, and the corresponding first relay or second relay is controlled to be closed according to the decoding result, and the closing time is disconnected after a certain time.

[0048] The first motor and the second motor are powered by a battery arranged in the hoist. The first relay and the second relay can be selected from the JQC-3ff type relay, and can be flexibly selected according to the actual situation, and the present embodiment is not limited.

[0049] As shown in Figure 2 ,Figure 4 As shown, two multi-point hoisting balancing devices are arranged in a group. Generally, the bridge direction is longitudinal, and the vertical direction is transverse. The two multi-point hoisting balancing devices can be arranged transversely or longitudinally. As shown, when arranged transversely, the longitudinal and transverse adjustments can be made; as shown, when arranged longitudinally, only longitudinal adjustment can be made. As shown, when multiple groups of multi-point hoisting balancing devices are arranged together, that is, multiple rows and multiple columns are arranged, longitudinal and transverse adjustments can be made. Figure 2 Figure 4 Figure 3

[0050] In one or more groups of multi-point hoisting balancing devices, multiple communication channels are provided between the signal transmitter 301 and each controller 302. The signal transmitter 301 communicates wirelessly with the controller 302 in each multi-point hoisting balancing device through the corresponding communication channel, that is, the signal transmitter 301 sends instructions to the corresponding controller 302 through different communication channels to avoid mutual interference. The communication channel switching button is provided on the manual transmission device.

[0051] When multiple groups of multi-point hoisting balancing devices are used for hoisting together, the automatic transmission device, that is, the computer, can send corresponding instructions to the target controller 302 according to the pre-designed hoisting height, hoisting inclination, and other information, and set the sending order of the corresponding instructions. Each controller 302 controls the first motor and / or the second motor according to the instructions to realize the coordinated driving of multiple motors to the corresponding winch, adjust the angle of the pulley system 2, and finally realize the adjustment of the pose of the component. It should be noted that the sending program used by the computer when sending instructions is the existing program, and does not involve improvement in the software program.

[0052] When adjusting the inclination angle of the hoisted component, the controller 302 can first drive the winch to keep a certain height between the first cross beam 101 and the second cross beam 102 to meet the space height required for inclination angle adjustment. The inclination angle adjustment is realized by the forward and reverse rotation of the winch and the cooperation of the rotation number limitation.

[0053] In some embodiments, when the controller 302 does not receive the instructions transmitted by the signal transmitter 301, only the rotation number of the corresponding first motor and second motor is controlled to realize the self-balancing of the pulley system 2 to ensure that the pose of the steel box girder or the prefabricated component is not affected by the wind load and the distribution of the hoisting point during the hoisting process.

[0054] Working principle detailed description:

[0055] As shown, Figure 1 , Figure 5 ​​​​As shown, when the multi-point hoisting balancing device is used for hoisting construction, if a travelling crane is used, the two lifting rings of the first cross beam 101 are connected by a steel wire rope and fixed on the lifting hook for hoisting, if a hanging basket is used for hoisting, the middle part of the web of the first cross beam 101 can be clamped by a clamp for hoisting, and the second cross beam 102 is fixed on the steel box girder or the prefabricated component through the lock buckle 105 or the steel cable fixing member. During hoisting, according to the pre-set inclination angle of the component, the signal transmitter 301 transmits an instruction, the controller 302 receives the instruction and controls the first motor or the second motor to drive the winch to adjust the length of the steel cable, so as to adjust the inclination angle of the steel box girder or the prefabricated component, thereby meeting the inclination requirement of the design state or avoiding obstacles by inclination, and meeting the construction technical requirement. When one or more groups of multi-point hoisting balancing devices are used for hoisting construction, the signal transmitter 301 sends corresponding instructions to each controller 302 through different communication channels, and the controller 302 executes the operation according to the instructions.

[0056] Specifically, when the component has no angle inclination requirement, the controller 302 can control the motor to drive the winch to rotate a number of turns, so that the lengths of the two steel cables are the same, so as to ensure that the steel box girder or the prefabricated component is not affected by the distribution of the lifting points during hoisting to maintain balance, and also to ensure that the steel box girder or the prefabricated component is not affected by external factors such as wind load to maintain its own balance, especially when a hanging basket is used for construction, the balance of the hanging basket itself can be ensured to ensure the personal safety of the construction personnel and improve the hoisting construction efficiency.

[0057] When there is an obstacle in the hoisting path of the steel box girder or the prefabricated component or there is an angle inclination requirement in the design state, the on-site construction personnel can transmit an instruction through the signal transmitter 301 (manual transmission device), and the controller 302 receives the instruction to control the motor to drive the winch to adjust the length of the steel cable 208 to realize the inclination of the steel box girder or the prefabricated component, and the inclination angle is linearly changed, thereby improving the hoisting construction efficiency.

[0058] When a multi-row, multi-column and multi-lifting-point balancing device is used, the computer can send an instruction, the controller 302 receives the instruction to control the motor to drive the winch to adjust the length of the steel cable 208 in real time to realize the inclination of the steel box girder or the prefabricated component, and the inclination angle is linearly changed, thereby improving the hoisting construction efficiency.

[0059] The multi-point hoisting balancing device can be used in travelling crane hoisting construction and hanging basket hoisting construction, the size of the device can be adjusted to meet the hoisting load and size requirements of the steel box girder or the prefabricated component, or the size of the device can be reduced to meet the requirements of the hanging basket construction to ensure the personal safety of the high-altitude construction personnel and improve the hoisting construction efficiency.

[0060] Embodiment two

[0061] This embodiment provides a multi-point hoisting balancing system, including a hoisting member and at least one multi-point hoisting balancing device fixed to the hoisting member. The number and arrangement of the multi-point hoisting balancing devices are set according to the size of the hoisting member.

[0062] like Figure 2 As shown, when hoisting small, integral steel box girders, two transverse rows of multi-point lifting and balancing devices are used. This device can be used for both land-based crane hoisting of steel box girders and basket hoisting of steel box girders on cross-sea bridges. When using a single crane, four lifting rings can be connected by steel cables and fixed to a double-ended hook for hoisting. When using two cranes, steel cables can be passed through two lifting rings and fixed to the hook for hoisting. When using a basket hoisting, a clamp can be used to clamp the upper middle portion of the upper web of the first crossbeam for hoisting.

[0063] During the hoisting process, commands can be sent through the signal transmitter, and the controller can control the motor to drive the winch to adjust the steel cable. The different lengths of the steel cables retracted and extended by the four winches can be used to adjust the overall posture of the steel box girder to meet the needs of avoiding obstacles during the hoisting construction process, improve the flexibility of the hoisting construction, and improve the efficiency of the hoisting construction.

[0064] In other embodiments, Figure 3 As shown in the figure, when hoisting a large section of an integral steel box girder, two rows of crossbeams and two longitudinal columns of multi-point hoisting balancing devices are used, and the overall position of the steel box girder is adjusted by eight winches with different lengths of retracted and released steel cables.

[0065] In other embodiments, Figure 4 As shown in the figure, when lifting a large section of steel box girder, two longitudinal rows of multi-point lifting balancing devices are used, and the overall position of the steel box girder is adjusted by retracting and releasing steel cables of different lengths using four winches.

[0066] During the hoisting process, instructions can be sent through the computer, and the controller can control the motor to drive the winch to achieve real-time retraction and extension of the steel cable. When the steel box girder reaches the specified height, the four winches can retract and extend the steel cables to different lengths to achieve precise adjustment of the overall position of the steel box girder to meet the requirements of angle tilt in the design state, improve the accuracy of hoisting construction, avoid wasting time in repeated lifting and lowering operations, and improve hoisting construction efficiency.

[0067] If there is no need for angle tilt during the lifting process, the controller can control the motor to drive the winch to retract and release the steel cable in real time, ensuring that the component will maintain balance and will not lose control of its position and collide with obstacles due to wind load or the distribution of lifting points, thereby improving the safety and efficiency of the lifting construction.

[0068] The winch retracts and releases the steel cable to make the pulley system work, and the pulley system can realize linear change of the inclination angle of the second cross beam, that is, linear change of the inclination angle of the steel box girder or the prefabricated component. When the initial spacing between the first cross beam and the second cross beam is large enough, that is, the steel cable of the pulley system is long enough, a large range of inclination angle change can be realized to meet the requirement of different inclination angles during hoisting construction.

[0069] The specific embodiments of the utility model are described above in combination with the drawings, but are not a limitation on the protection scope of the utility model, and those skilled in the art should understand that various modifications or deformations made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
