Description

Technical Field

[0001] The invention belongs to the technical field of tower crane lifting devices, and in particular refers to a tower crane lifting device based on hydraulic control. Background Art

[0002] During the installation of a tower crane, the top boom, counterweight and other devices are generally all installed on the ground, and then the top is continuously lifted up through a jacking device. In the process, standard sections are continuously installed upwards on the base of the tower crane, thereby achieving the effect of increasing the overall height of the tower crane. In this process, the installed boom can be used to lift the standard sections to be installed.

[0003] Since the standard section needs to be moved horizontally to the specified position at an appropriate time after the lifting is completed, it is generally necessary to set up an independent driving module and execution module for horizontal movement, which undoubtedly increases the structural complexity and the load-bearing capacity of the top workbench.

[0004] The currently commonly used technical solutions are not only complex in structure and operation control logic, but also generally require manual step-by-step control, which greatly increases the difficulty and workload of tower crane installation. Summary of the invention

[0005] In view of the above situation, in order to simplify the structure and operating steps, the present invention proposes a tower crane lifting device based on hydraulic control that can achieve lateral movement without an independent lateral movement drive module; through the linkage control of the adaptive lateral movement control mechanism and the reciprocating lateral movement mechanism, the lateral movement module can be reset and kinetic energy can be accumulated during the climbing process of the vertical climbing mechanism, and after the climbing is completed, the kinetic energy accumulated during the climbing process can automatically move the top standard unit to the specified position.

[0006] Moreover, in order to reduce the lateral movement resistance of the standard unit, the present invention also arranges fixed support rollers and telescopic support rollers for support under the standard unit. However, after installation, when the telescopic support rollers rise with the climbing frame, they will interfere with the standard unit. In order to solve this problem, the present invention creatively proposes an adaptive telescopic support mechanism, which automatically controls the retraction of the telescopic support rollers during the climbing stage through the hydraulic changes in the hydraulic control cylinder during the climbing and lateral movement processes, thereby achieving the technical effect of adaptive avoidance.

When the climbing hydraulic cylinder 14 extends, the climbing hook body 16 hooks the cross bar 20 and lifts the climbing frame 6 upward as a whole. In this process, the one-way block body 13 will also slide from one fixed block 23 to the upper fixed block 23. When the one-way block body 13 contacts the bottom of the fixed block 23, the one-way block body 13 will rotate relative to the one-way block base 12 to avoid position, and the one-way block body 13 will return to the horizontal after completely passing the fixed block 23; at this time, the climbing hydraulic cylinder 14 is controlled to retract, and the one-way block body 13 will press on The one-way block base 12 and the fixed block 23 form a stop; then when the climbing hydraulic cylinder 14 retracts, the climbing hook claw body 16 will leave the cross bar part 20 and rise along with the telescopic rod of the climbing hydraulic cylinder 14; when the climbing hook claw body 16 contacts the bottom of an upper cross bar part 20, the climbing hook claw body 16 will avoid the position by a small deflection relative to the climbing hook claw base 15. After the avoidance is completed, the climbing hook claw body 16 will be reset under the elastic force of the hook claw holding spring 17, so that the climbing hook claw body 16 can hook the upper part of the cross bar part 20 when the climbing hydraulic cylinder 14 is extended next time.

[0082] The climbing frame 6 can be intermittently lifted by reciprocating extension and retraction of the climbing hydraulic cylinder 14 .

[0083] When climbing begins, the electromagnetic telescopic rod 37 is in a power-off extended state. At this time, the climbing frame 6 will rise together with the electromagnetic barb assembly 26 through the piston control rope 34. When the barb plate 36 hooks the bottom of the crossbar 20, the climbing frame 6 will stop rising. At this time, the climbing frame 6 continues to rise, and the piston control rope 34 will pull the control piston 30 down;

[0084] During the process of the control piston 30 descending, negative pressure is generated inside the hydraulic control cylinder 27 and the liquid in the telescopic control cylinder 48 is sucked into the hydraulic control cylinder 27. At this time, the telescopic piston rod 49 is retracted. Therefore, in the climbing stage, the telescopic support roller 52 is in a retracted state and will not interfere with the installed standard unit 2.

[0085] During the process of controlling the piston 30 to descend, the tension rope 54 will also be released. After the tension of the tension rope 54 is lost, the transverse slider 43 will slide toward the end direction of the cantilever support assembly 9 under the elastic force of the elastic rope 44. During this process, if the sliding block 45 contacts the standard unit 2 placed on the cantilever support assembly 9, it will avoid the position through the retraction of the block reset spring 46 and the sliding of the sliding block 45. After crossing the vertical rod 21, the sliding block 45 will be reset under the elastic force of the block reset spring 46.

[0086] After the climbing is completed, the top of the installed topmost standard unit 2 should be slightly lower than the bottom of the standard unit 2 to be installed. At this time, the electromagnetic telescopic rod 37 is energized to retract it. After the electromagnetic telescopic rod 37 is locked, the hook plate 36 can rotate relative to the hook base 35. At this time, the hook plate 36 cannot hook the bottom of the cross bar 20, and the control piston 30 will rise and reset under the elastic force of the piston lifting spring 32. At this stage, the adjustable flow limiting valve 29 can limit the flow rate, so the reset process of the control piston 30 is relatively slow.

[0087] By rotating the adjustable flow limiting valve 29, the speed of the reset of the control piston 30 can be actively adjusted;

[0088] During the process of the control piston 30 rising and returning to its original position, a positive pressure is generated inside the hydraulic control cylinder 27 and the liquid in the hydraulic control cylinder 27 is pumped into the telescopic control cylinder 48. At this time, the telescopic piston rod 49 is extended, so that in the lateral movement stage, the telescopic support roller 52 is in an extended state and can guide and support the bottom of the standard unit 2 in a rolling manner.

[0089] When the control piston 30 is lifted and reset, the tension rope 54 pulls the transverse sliding block 43 to move horizontally and reset. At this time, the sliding block 45 presses against the side of the vertical rod 21 and pushes the standard unit 2 to be installed to move horizontally to the specified position.

[0090] Then, the standard unit 2 to be installed is connected to the installed standard unit 2 by bolts and the next installation step can be carried out.

[0091] After all are installed, the adaptive transverse movement control mechanism 3, the reciprocating transverse movement mechanism 4 and the adaptive telescopic support mechanism 5 can be disassembled and lifted to the ground first, and then the auxiliary mechanism specially used for disassembly can be installed when the tower crane needs to be disassembled.
