Description

Technical Field

[0001] This invention relates to the field of vibratory compactor lifting construction technology, and in particular to a lifting device and a vibratory compactor control system. Background Technology

[0002] A vibratory compactor is a specialized machine used in vibratory compaction construction, and it comes in hydraulic and electric versions. It generates horizontal vibration to compact the fill material and surrounding soil, thereby improving the bearing capacity of the foundation, reducing settlement, increasing foundation stability, and enhancing resistance to seismic liquefaction. Currently, the electric vibratory compactor is more commonly used in China. It uses a motor installed inside the vibratory compactor to drive a polarized rotor, generating horizontal vibration to complete processes such as hole drilling, compacting the added stone, and pile formation.

[0003] In actual production, we found certain problems in the use of vibratory compactors. The vibratory compactor is repeatedly lifted and lowered by a traveling hoisting device to complete the work. Before construction, the wire rope is prevented from falling by installing wedges, but during construction, workers need to disassemble and adjust it, which is time-consuming and laborious. During construction, the sudden situation of the wire rope breaking due to the vibratory compactor rising too quickly was not considered. How to monitor and maintain in a timely manner before and after a safety accident to prevent further deterioration is an urgent problem to be solved. Summary of the Invention

[0039] Example 1

[0040] Reference Figures 1-7 This is the first embodiment of the present invention. This embodiment provides a lifting device for a vibratory impactor, which can be accurately adjusted by delay according to the monitoring cycle through motor drive. It is simple to operate and difficult to make mistakes. After the adjustment is completed, the wire rope can be automatically locked to avoid the trouble of disassembly.

[0041] Specifically, the main unit 100 includes a vibratory impactor assembly 101, a winch assembly 102 attached to the vibratory impactor assembly 101, a start / stop delay control assembly 103 disposed at the bottom of the winch assembly 102, a speed sensor 104 connected to the start / stop delay control assembly 103 and disposed on the winch assembly 102, and a power supply unit 105 connected to the winch assembly 102 and the start / stop delay control assembly 103 respectively.

[0042] Furthermore, the winch assembly 102 includes a winch 102a, a steel rope 102b disposed on the winch 102a, a hook 102c connected to the steel rope 102b, a mounting bracket 102d disposed at the bottom of the winch 102a, a lower rope opening 102e disposed on one side of the mounting bracket 102d, a first elastic clamping block 102f and a second elastic clamping block 102g disposed on both sides of the lower rope opening 102e, and a gradient arc block 102h fixedly connected to one side of the second elastic clamping block 102g;

[0043] The first elastic clamping block 102f is fixedly connected to the mounting bracket 102d, and the second elastic clamping block 102g is inserted into the mounting bracket 102d.

[0044] Furthermore, the start / stop delay control component 103 includes a raised housing 103a, a screw drive 103b threadedly connected to the raised housing 103a, a start / stop control 103c movably connected to the end of the screw drive 103b, a first connector 103d and a second connector 103e disposed on both sides inside the raised housing 103a, a first control track 103f disposed below the first connector 103d, and a second control track 103g disposed below the second connector 103e.

[0045] The power line of the speed sensor 104 is located inside the first connector 103d; the power line of the winch 102a is located at the second connector 103e.

[0046] The first control track 103f includes a first oblique outer groove 103f-1, a first straight long groove 103f-2 connected to the first oblique outer groove 103f-1, a first oblique inner groove 103f-3 connected to the first straight long groove 103f-2, and a first straight short groove 103f-4 connected to the first oblique inner groove 103f-3;

[0047] The second control track 103g includes a second oblique outer groove 103g-1, a second straight short groove 103g-2 connected to the second oblique outer groove 103g-1, a second oblique inner groove 103g-3 connected to the second straight short groove 103g-2, and a second straight long groove 103g-4 connected to the second oblique inner groove 103g-3;

[0048] The length of the first straight long groove 103f-2 is greater than the length of the second straight short groove 103g-2; the length of the first straight short groove 103f-4 is less than the length of the second straight long groove 103g-4.

[0049] Furthermore, the screw drive component 103b includes a motor 103b-1, a cross-shaped limiting transmission rod 103b-2 connected to the motor 103b-1, a threaded rod 103b-3 inserted into the cross-shaped limiting transmission rod 103b-2, and a cooperating disc 103b-4 disposed at the end of the threaded rod 103b-3.

[0050] Furthermore, the start / stop control control 103c includes a driven block 103c-1 movably connected to the screw drive 103b, two sets of telescopic rods 103c-2 disposed on both sides of the driven block 103c-1, an arc-shaped top pressing block 103c-3 connected to the end of the telescopic rod 103c-2, and a trigger rod 103c-4 disposed at the bottom of the arc-shaped top pressing block 103c-3;

[0051] Preferably, the two sets of trigger rods 103c-4 are respectively disposed within the first control track 103f and the second control track 103g. The bottom of the trigger rod 103c-4 is set as a smooth hemispherical shape, so it can change track and move along the direction of the control track during movement, thereby controlling the extension and retraction of the telescopic rod 103c-2, so that the arc-shaped top pressing block 103c-3 can periodically lift or lower the semi-arc platform 103d-1.

[0052] Furthermore, the first connector 103d and the second connector 103e have the same structure; the first connector 103d includes a semi-arc platform 103d-1 that carries the power line of the speed sensor 104, two sets of springs 103d-2 disposed at the bottom of both sides of the semi-arc platform 103d-1, an insulating plate 103d-3 disposed on one side of the semi-arc platform 103d-1, and a power-conducting plate 103d-4 disposed on the top of the insulating plate 103d-3; the power-conducting plate 103d-4 is made of conductive material.

[0053] The power supply line of the power supply unit 105 is fixedly connected to the power board 103d-4.

[0054] It should be noted that the vibratory shock assembly 101, power supply group 105, winch 102a and speed sensor 104 in this embodiment can adopt existing technology. The power supply group 105 consists of two independent power supplies connected to two sets of lines respectively.

[0055] Reference Figure 3 and Figure 4 For ease of understanding, the power line connecting the speed sensor 104 to the start-stop delay control component 103 is defined as the first power line J1; the power line connecting the motor power end of the winch 102a to the start-stop delay control component 103 is defined as the second power line J2; the power supply line connecting the first connector 103d to the power supply group 105 is defined as the first power supply line G1; and the power supply line connecting the second connector 103e to the power supply group 105 is defined as the second power supply line G2. Initially, the first power line J1 and the second power line J2 are kept de-energized by contact with the insulating plate 103d-3.

[0056] Preferably, the start / stop control control 103c further includes a toggle block 103c-5 connected to the bottom of the driven block 103c-1; the end of the toggle block 103c-5 contacts one side of the gradient arc block 102h. The second elastic clamping block 102g is fixedly connected to the gradient arc block 102h. The bottom of the second elastic clamping block 102g is provided with a limit block that inserts into the limit groove of the mounting bracket 102d, thus the second elastic clamping block 102g can be limited to linear movement under external force. The first elastic clamping block 102f and the second elastic clamping block 102g can be made of rubber. A spring (not shown in the figure) can be provided on one side of the gradient arc block 102h for resetting the gradient arc block 102h and the second elastic clamping block 102g.

[0057] Furthermore, the elevated housing 103a includes a first power port 103a-1 and a second power port 103a-2 disposed on one side. Both the first power port 103a-1 and the second power port 103a-2 have sufficient slack to facilitate the lifting and clamping of the lines.

[0058] It should be noted that the threaded rod 103b-3 of the screw drive component 103b is hollow, and its inner cavity is adapted to be inserted into the cross-shaped limiting transmission rod 103b-2. The lifting housing 103a is provided with a threaded opening for threaded connection with the threaded rod 103b-3. Therefore, when the motor 103b-1 drives the threaded rod 103b-3 to rotate, the threaded rod 103b-3 will gradually screw into the lifting housing 103a through the threaded opening and gradually disengage from the cross-shaped limiting transmission rod 103b-2; thread The top of rod 103b-3 contacts and abuts against the inner side of driven block 103c-1. The cooperating disc 103b-4 at the outer end of threaded rod 103b-3 passes through driven block 103c-1 and contacts its outer side. The cooperating disc 103b-4 is movably connected to driven block 103c-1. Therefore, when threaded rod 103b-3 is screwed in, it pushes driven block 103c-1 to move via its top end; when screwed out, the cooperating disc 103b-4 drives driven block 103c-1 backward. The bottom of driven block 103c-1 is inserted into a slot in the raised housing 103a for limiting, allowing it to move linearly. The self-locking connection between threaded rod 103b-3 and the threaded opening ensures stable connectivity during each monitoring cycle and maintains tightness on the wire rope after construction, preventing it from falling.

[0059] When in use, the monitoring and adjustment can be carried out in three stages according to the construction process. No complicated operations are required. The overall control only requires controlling the 103b-1 motor drive, which is simple and convenient. It is easy to handle emergencies, such as emergency shutdown of the winch and subsequent observation, to prevent the situation from deteriorating.

[0060] The first stage is the start-up stage: the winch assembly 102 can be installed on any mobile lifting device. Then, the worker hoists the vibratory impactor assembly 101 and the winch assembly 102. Next, the control motor 103b-1 is started, causing the threaded rod 103b-3 to screw into the elevated housing 103a, causing the driven block 103c-1 to move linearly. The two sets of trigger rods 103c-4 respectively enter the first inclined outer groove 103f-1 and the second inclined outer groove 103g-1. The telescopic rod 103c-2 is extended, causing the two sets of arc-shaped top pressure blocks 103c-3 to... The semi-arc platform 103d-1 is squeezed, causing the two sets of semi-arc platforms 103d-1 to rise. When the two sets of trigger rods 103c-4 enter the first linear longitudinal groove 103f-2 or the second linear short groove 103g-2 respectively, the first power line J1 and the second power line J2 are connected to the power board 103d-4 respectively. The first power line J1 is connected to the first power supply line G1, and the second power line J2 is connected to the second power supply line G2. The speed sensor 104 and the winch 102a start to work, and the speed sensor 104 collects the speed of the wire rope in real time.

[0061] The second stage is the emergency braking observation stage or the construction completion observation stage: When a sudden situation requires braking, motor 103b-1 continues to start, driven block 103c-1 moves, and when the trigger rod 103c-4 at the bottom of the second connector 103e enters the first inclined inner groove 103f-3 and reaches the intersection of the first inclined inner groove 103f-3 and the first straight short groove 103f-4, at this time the trigger rod 103c-4 at the bottom of the first connector 103d reaches... Upon reaching the end of the first straight longitudinal groove 103f-2, the arc-shaped top pressure block 103c-3 disengages from the bottom of the semi-arc platform 103d-1, causing the semi-arc platform 103d-1 to fall back and release from clamping. The second power line J2 disengages from the power board 103d-4, while the first power line J1 remains in contact with the power board 103d-4. Therefore, the winch 102a is immediately de-energized, but the speed sensor 104 continues to operate to monitor the wire rope in real time, preventing the situation from deteriorating further.

[0062] The third stage is the locking and clamping stage: After the emergency is resolved or the construction is completed, the motor 103b-1 continues to start. When the trigger rod 103c-4 at the bottom of the second connector 103e enters the first straight longitudinal groove 103f-2 and moves in the groove, the trigger rod 103c-4 at the bottom of the first connector 103d enters the first oblique inner groove 103f-3 and finally enters the first straight short groove 103f-4. Therefore, the winch assembly 102 remains closed. The speed sensor 104 stops working after the trigger rod 103c-4 enters the first straight short groove 103f-4. When the trigger rod 103c-4 moves in the first straight short groove 103f-4, the toggle block 103c-5 moves with the driven block 103c-1 and squeezes the gradually curved block 102h to make the second elastic clamping block 102g approach the first elastic clamping block 102f, thus clamping the wire rope.

[0063] In summary, the system uses a motor-driven mechanism to accurately adjust the delay according to the monitoring cycle. It is simple to operate and prone to errors. Furthermore, it can automatically and selectively start and stop the corresponding equipment according to construction needs, avoiding waste of resources and adverse consequences caused by accidental operation. After the adjustment is completed, the wire rope can be automatically locked to avoid the trouble of disassembly.

[0064] Example 2

[0065] Reference Figure 8 The second embodiment of the present invention provides a vibratory impactor control system, which can control the start and stop of the winch through a remote control module to adjust the lifting and lowering of the vibratory impactor in a timely manner.

[0066] Specifically, the control system 200 includes a wireless transceiver module 201 connected to the speed sensor 104, a receiving module 202 wirelessly connected to the wireless transceiver module 201, and a remote control module 203 wirelessly connected to the start / stop delay control component 103.

[0067] Furthermore, the control system 200 also includes a display module 204 connected to the receiving module 202.

[0068] It should be noted that the wireless transceiver module 201, receiving module 202, remote control module 203, and display module 204 in this embodiment can all adopt existing technologies. The wireless transceiver module 201 and receiving module 202 can use 485 communication to wirelessly send and receive collected information. The remote control module 203 can be a laptop, mobile phone, or remote control terminal, used to display the received information through the display module 204 and to remotely control the start / stop delay adjustment component 103.

[0069] In use, the data collected in real time by the speed sensor 104 can be transmitted to the receiving module 202 via the wireless transceiver module 201. The receiving module 202 transmits the collected data to the remote control module 203 for processing and displays it through the display module 204. The staff can adjust the start-stop delay control component 103 according to the real-time changes in data to achieve precise control.

[0070] In summary, the hoist's lifting and lowering can be adjusted in a timely manner by controlling the start and stop of the winch through a remote control module.
