Description

Technical Field

[0001] This invention belongs to the field of linear large-volume casting construction technology, specifically, it relates to a multi-section lifting gantry type continuous casting equipment and method. Background Technology

[0002] In linear, large-volume pouring construction such as large channels, traditional pouring equipment has significant shortcomings, making it difficult to meet the requirements of efficient, safe, and multifunctional construction. Specific problems are as follows: 1. Low pouring efficiency and significant interference: Traditional gantry cranes have a small single pouring capacity (≤5m³ / h), requiring multiple machines to work together to meet the construction schedule. The overlapping operating trajectories and material transfer conflicts between the machines not only result in low pouring efficiency (overall efficiency ≤20m³ / h) but also pose safety risks such as collisions.

[0003] 2. Limited lifting range and poor stability: Most existing lifting pouring equipment has a single or two-section lifting structure with a maximum lifting height of ≤5m, which cannot adapt to complex working conditions such as channel slopes (height 6-15m) and deep foundation pits; moreover, the lifting mechanism is mostly hydraulically driven, which is prone to lifting jamming or tilting due to hydraulic leakage, resulting in poor operating accuracy (±50mm).

[0004] 3. Limited functionality and poor adaptability: Traditional equipment can only perform a single pouring function and cannot meet the needs of hoisting (such as the transfer of steel bars and formwork) and carrying (such as the transportation of small machinery) during construction. Additional equipment such as cranes and forklifts are required, which increases construction costs and site occupation.

[0005] 4. Poor continuity of concrete delivery: The connection between the pouring equipment and the material supply system (such as mixer trucks and conveyor belts) relies on manual adjustment. When the equipment is raised, lowered or moved, the hopper is easily misaligned and concrete leaks, which can lead to pouring interruption and affect the construction quality.

[0006] 5. Poor adaptability to linear construction: Channel construction is a long-distance linear operation (single section length ≥ 100m). Traditional equipment requires frequent disassembly and track transfer, resulting in low transfer efficiency (single transfer ≥ 2 hours) and inability to achieve continuous linear pouring. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a multi-section lifting gantry type continuous pouring equipment and method to realize linear large-volume continuous pouring construction operations.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a multi-section lifting gantry continuous pouring equipment, including a lifting mechanism and a pouring system. The lifting mechanism is provided in multiple sets and symmetrically arranged on both sides of the channel. The lifting mechanisms on both sides of the channel are connected by longitudinal beams, and the upper ends of the lifting mechanisms on the same side of the channel are connected by cross beams. The multiple sets of lifting mechanisms, longitudinal beams and cross beams form a gantry structure. Each lifting mechanism includes multiple lifting columns. The topmost lifting column has wheels at its bottom, and tracks on both sides of the channel are designed to cooperate with the wheels. The lifting column includes a column cylinder with a rotating shaft inside. The rotating shaft is rotatably mounted inside the column cylinder via bearings and is driven by a lifting drive motor. The rotating shaft has helical blades, and rollers are rolled in cooperation with the helical blades. The rollers are rotatably mounted on a wheel axle, which is mounted on a wheel frame. The wheel frame has a sliding rod, and the side wall of the column cylinder has a groove that cooperates with the sliding rod. The sliding rod of the upper section of the lifting column is connected to the next adjacent section of the lifting column, and the sliding rod of the bottommost lifting column is connected to the lifting base plate. The pouring system includes pouring equipment, which is installed on the lifting base plate.

[0009] In the preferred embodiment, the lifting mechanism is provided in four sets, with two sets symmetrically arranged on both sides of the channel.

[0010] In the preferred embodiment, each lifting mechanism is equipped with three lifting columns.

[0011] In a preferred embodiment, the pouring system further includes a front hopper and a telescopic hopper mechanism. The front hopper is mounted on the uppermost lifting column of one of the lifting mechanisms. The lower end of the front hopper is fitted inside the telescopic hopper mechanism, which includes multiple telescopic hopper sections that are nested together. Lifting rings are provided on the outer sides of both the front hopper and the telescopic hopper. Ear plates are provided on the outer sides of the telescopic hopper. The height of the ear plate of each telescopic hopper section is higher than the height of the lifting ring. The lifting ring on the outer side of the front hopper and the ear plate of the uppermost telescopic hopper, as well as the lifting ring on the outer side of the previous telescopic hopper section and the ear plate on the outer side of the next telescopic hopper section, are connected by springs. In use, the lowermost telescopic hopper extends into the hopper of the pouring equipment and connects to the receiving hopper of the pouring equipment.

[0012] In the preferred embodiment, when the telescopic bucket mechanism is not under force, the next telescopic bucket section extends upward to the outside of the previous telescopic bucket section under the action of the spring, and the telescopic bucket mechanism shrinks to its minimum length.

[0013] In a preferred embodiment, the front hopper is fixed or hinged to the cylinder of the topmost lifting column.

[0014] In a preferred embodiment, the pouring equipment is a pouring truck.

[0015] In a preferred embodiment, the pouring equipment is a tire-mounted, tracked, or non-mobile pouring vehicle, and a belt-driven or bucket-type pouring equipment is selected.

[0016] In a preferred embodiment, a cable reel is provided on the longitudinal or transverse beam to reel in and unload the control cable of the pouring equipment according to the height of the lifting base plate.

[0017] In a preferred embodiment, the lifting base plate is a hollow steel structure, with telescopic plates at both ends. The telescopic plates are inserted into the cavity of the lifting base plate, and a rack is provided on the outer side of the telescopic plates. A motor is provided in the cavity of the lifting base plate, and a gear that meshes with the rack is provided on the motor shaft.

[0018] In a preferred embodiment, the cavity of the lifting base plate is provided with a plurality of limiting pulleys, which are arranged on the upper and lower sides of the telescopic plate.

[0019] In a preferred embodiment, the extended end of the telescopic plate is provided with a ramp.

[0020] In a preferred embodiment, a driver's cab is provided on the longitudinal or transverse beam for on-site control and operation.

[0021] The present invention also provides an operation method for a multi-section lifting gantry continuous pouring equipment, which is based on the above-mentioned multi-section lifting gantry continuous pouring equipment and includes the following steps: Step 1: Pre-operation preparation: Check the status of the lifting mechanism and the pouring system; drive the traveling wheels to roll along the track and move the equipment to the concrete platform where the pouring equipment needs to be loaded; start the lifting drive motor to drive the rotating shaft inside the lifting column to rotate. The spiral blades on the rotating shaft and the rollers roll together to make the slide bar slide along the slide groove and adjust the height of the lifting base plate to be level with the concrete platform. Step 2: Telescopic plate overlap: Start the motor in the cavity of the lifting base plate. The motor drives the gear to rotate. The gear meshes with the rack on the outside of the telescopic plate, causing the telescopic plate to extend out of the cavity of the lifting base plate, so that the extended end of the telescopic plate overlaps with the concrete platform to form a passage for the equipment. Move the crane or pouring equipment to the lifting platform for hoisting, pouring, or unloading operations. When pouring, execute steps 3-5: Step 3: Assembly of the pouring equipment: Move the pouring equipment along the telescopic plate to the lifting base plate, adjust the posture of the pouring equipment and extend its outrigger cylinders to fix it; pull the telescopic bucket mechanism to stretch the spring and extend the lowest telescopic bucket into the hopper of the pouring equipment. Connect the lifting ring on the outside of the telescopic bucket to the connecting ring of the receiving hopper of the pouring equipment through the steel wire rope to fix the telescopic bucket mechanism to the pouring equipment. Step 4: Adjustment of pouring operation: Control the traveling wheels to move along the track and transfer the equipment to the target pouring position; restart the lifting drive motor and adjust the extension length of the lifting column so that the pouring end of the pouring equipment is aligned with the pouring position. During the process, the cable reel trolley will simultaneously retract and extend the control cable of the pouring equipment according to the height change of the lifting base plate. Step 5: Continuous pouring: Supply concrete to the front hopper of the pouring system. The concrete flows from the front hopper into the telescopic hopper of the telescopic hopper mechanism and finally into the hopper of the pouring equipment. Control the start of the pouring equipment to transport the concrete to the pouring location until the pouring operation in that area is completed.

[0022] In a preferred embodiment, during step 2, when the telescopic plate is adjusted, several limiting pulleys in the cavity of the lifting base plate roll against the upper and lower sides of the telescopic plate to guide the telescopic plate's extension and retraction direction, while limiting the telescopic plate's offset in the vertical direction, ensuring that the telescopic plate accurately overlaps with the concrete platform.

[0023] In the preferred embodiment, when performing hoisting operations, steps 6-9 are executed: Step 6: Move the crane along the telescopic platform onto the lifting platform, extend the outrigger cylinders of the crane and fix them to the lifting platform to ensure the stability of the crane; Step 7: Control the traveling wheels to move along the track to the location where the suspended object is stored, start the lifting drive motor to adjust the height of the lifting column, and align the crane hook with the suspended object; Step 8: Operate the crane to extend the boom, hook the load and lift it up, then retract the boom to place the load within the safe range of the lifting platform; Step 9: Move the mobile equipment to the target lifting position, adjust the height of the lifting column to the preset lifting height, and extend the boom of the crane to lower the load to the target position to complete the lifting operation.

[0024] In the preferred embodiment, when performing the unloading operation, steps 10-12 are executed: Step 10: The forklift travels along the telescopic platform to the lifting platform, unloads the goods to be transported onto the load-bearing area of ​​the lifting platform, and then the forklift exits along the telescopic platform. Step 11: Control the lifting drive motor to drive the lifting column to retract and lower the lifting base plate to the ground height of the unloading platform or construction groove; Step 12: The forklift or lifting equipment enters the lifting platform along the telescopic plate, transfers the goods to the construction work surface, and completes the cargo transportation operation.

[0025] In the preferred embodiment, in step 5, after all areas have been poured, the supply of concrete to the forward hopper is stopped, the pouring equipment is controlled to retract the pouring components, and the wire rope connection between the telescopic bucket and the pouring equipment hopper is released; the lifting drive motor is started to drive the lifting column to retract to its minimum length, so that the lifting base plate is lowered to the lowest position, and at the same time the cable reel retracts the control cable of the pouring equipment; the motor drive gear is started to rotate in the opposite direction, driving the telescopic plate to retract into the cavity of the lifting base plate; the traveling wheels are controlled to move along the track, and the equipment is parked at the end of the track or a preset safe area, and the main power supply of the equipment is turned off.

[0026] The multi-section lifting gantry type continuous pouring equipment and method provided by the present invention have the following beneficial effects: 1. Meets the requirements of various working conditions. This invention adopts a multi-stage lifting working column method, which can meet the needs of various working conditions such as pouring, hoisting, and transportation, and is highly innovative.

[0027] 2. The lifting mechanism of this invention completely solves the problems of small lifting range and unstable hydraulic drive of traditional equipment. Through the rolling cooperation of the spiral blades on the rotating shaft and the rollers, the slide bar slides along the slide groove to achieve a lifting range of 0~9m. It can cover scenarios that traditional equipment cannot reach, such as channel slopes and deep foundation pits, without the need to replace equipment due to the adjustment of the pouring height. The use of motor-driven spiral blade transmission replaces the traditional hydraulic drive, avoiding lifting jamming and tilting problems caused by hydraulic oil leakage, and improving the operation accuracy.

[0028] 3. The traveling wheels at the bottom of the topmost lifting column roll along the pre-set tracks on both sides of the channel. The tracks extend with the construction section, enabling continuous pouring over a long distance of more than 100m without the need for frequent track disassembly, thus greatly improving construction efficiency.

[0029] 4. The telescopic bucket mechanism in the pouring system solves the problems of misalignment and pouring interruption in traditional material supply. Multiple telescopic buckets are interlocked, and the front hopper and telescopic buckets, as well as adjacent telescopic buckets, are connected by springs. When the pouring equipment adjusts its height with the lifting base plate, the springs can automatically stretch or contract, causing the telescopic buckets to stretch and contract synchronously. The lowest telescopic bucket is always in close contact with the hopper of the pouring equipment to prevent concrete leakage.

[0030] 5. The lifting base plate is equipped with a telescopic plate, which solves the problems of difficult connection between traditional equipment and concrete platform and high risk of scaffolding overlap. The telescopic plate is driven by a motor to mesh with gears and racks to achieve a telescopic range of 0~2m. It can overlap concrete platforms with a height difference of ≤0.5m. The ramp at the extended end avoids bumping into steps and facilitates smooth passage for pouring trucks, cranes and forklifts.

[0031] 6. Wide range of applications. The device of this invention is well applicable to the preparation and pouring of large-volume concrete in places such as canals, canyons, and flat land. It has low requirements for the conditions of the application site and can be quickly promoted.

[0032] 7. High work efficiency. This invention can quickly realize the pouring of concrete by belt conveyor, and it is also convenient to connect with the conveyor belt conveyor of mixing plant, material supply line, etc. for pouring. The work efficiency is much higher than that of existing hanging tank pouring equipment. Attached Figure Description

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0035] Example 1: like Figures 1-2 As shown, a multi-section lifting gantry type continuous pouring equipment is provided. The gantry structure consists of multiple lifting mechanisms 100, longitudinal beams 300 and transverse beams 400. Preferably, there are 4 lifting mechanisms 100, which are symmetrically arranged on both sides of the channel, with 2 sets on each side.

[0036] The lifting mechanisms 100 on both sides of the channel are connected by longitudinal beams 300, and the upper ends of the lifting mechanisms 100 on the same side of the channel are connected by cross beams 400. Multiple sets of lifting mechanisms 100, longitudinal beams 300 and cross beams 400 form a rectangular gantry frame.

[0037] The symmetrically distributed four sets of lifting mechanisms (100) ensure balanced force distribution on the gantry, enabling it to withstand loads of ≥50t and preventing tilting caused by unilateral stress, thus guaranteeing safety during high-altitude operations. The longitudinal beams (300) and transverse beams (400) are constructed of Q355 steel with a bending strength of ≥345MPa, capable of withstanding strong winds ≤8 and vibrations during canal construction, ensuring the overall stability of the gantry. The gantry structure span is adaptable to canals 5-20m wide.

[0038] The longitudinal beam 300 or the transverse beam 400 is equipped with a driver's cab 800 for on-site control and operation. The driver's cab 800 has a built-in electrical control cabinet, operation panel and monitoring screen, which can display the lifting height, pouring volume and equipment status in real time, and supports switching between on-site control and remote control.

[0039] Each set of lifting mechanisms 100 includes multiple lifting columns 110. The topmost lifting column 110 is equipped with a traveling wheel 120 at its bottom. Tracks 500 that cooperate with the traveling wheel 120 are provided on both sides of the channel. The length of the track extends with the channel construction section. The traveling wheel 120 is driven by a variable frequency motor.

[0040] The wheels and rails work together to enable the equipment to move linearly along the channel without disassembly or relocation. The rails are pre-installed on both sides of the channel, so they do not occupy the pouring surface and protect the channel slope from damage caused by the equipment.

[0041] like Figure 1 , Figure 3 and Figure 4 As shown, the lifting column 110 includes a column cylinder 111, inside which is a rotating shaft 112. The rotating shaft 112 is rotatably mounted inside the column cylinder 111 via bearings. The rotating shaft 112 is driven by a lifting drive motor 113. The rotating shaft 112 is provided with a spiral blade 114. A roller 115 is in rolling engagement with the spiral blade 114. The roller 115 is rotatably mounted on a wheel axle 116. The wheel axle 116 is mounted on a wheel frame 117. The wheel frame 117 is provided with a sliding rod 118. The side wall of the column cylinder 111 is provided with a sliding groove 119 that mates with the sliding rod 118. The sliding rod 118 of the upper section of the lifting column 110 is connected to the adjacent lower section of the lifting column 110. The sliding rod 118 of the lowermost lifting column 110 is connected to the lifting base plate 600.

[0042] The power source for the lifting column 110 is the lifting drive motor 113 at the top of the column cylinder 111. When the lifting drive motor 113 starts, it directly drives the rotating shaft 112 connected to it to rotate around its own axis. The direction of rotation can be controlled by the forward and reverse rotation of the motor. Since the spiral blade 114 is fixedly connected to the outer surface of the rotating shaft 112, the rotation of the rotating shaft 112 will synchronously drive the spiral blade 114 to rotate in a circle around the axis of the rotating shaft 112 at the same angular velocity. The spiral trajectory of the spiral blade 114 forms a dynamic spiral surface as the column rotates. This spiral surface will generate an oblique force on the contacting roller. Because the roller's circumferential displacement is restricted by the slide groove 119, the slide groove 119 only allows the roller 115 to move vertically up and down along the height direction, and it cannot rotate around the axis 112 with the helical blade 114. This oblique force will be decomposed into two components, the circumferential component and the axial component. Under the continuous action of the axial component, the roller moves up and down along the slide groove 119 of the cylinder, thereby causing the corresponding slide rod 118 to move up and down, realizing lifting and lowering.

[0043] In practical use, each section of the lifting column 110 can be equipped with two sets of rollers 115 and slide bars 118, with the two sets of rollers spaced apart to improve the connection stability with the next section of the lifting column.

[0044] In this embodiment, each set of lifting mechanisms 100 is equipped with three sections of lifting column 110, which can achieve a lifting range of 0~9m to adapt to the adjustment of the pouring depth of the channel.

[0045] The pouring system 200 includes a pouring device 210, which is installed on the lifting base plate 600 and is adjusted in height synchronously with the lifting base plate 600.

[0046] like Figure 5 As shown, the pouring system 200 also includes a front hopper 220 and a telescopic hopper mechanism 230. The front hopper 220 is installed on the uppermost lifting column 110 of one of the lifting mechanisms 100. Specifically, the front hopper 220 is fixed or hinged to the column cylinder 111 of the uppermost lifting column 110. The lower end of the front hopper 220 is fitted inside the telescopic bucket mechanism 230. The telescopic bucket mechanism 230 includes multiple telescopic buckets 231 that are nested together. Lifting rings 232 are provided on the outside of both the front hopper 220 and the telescopic bucket 231. Ear plates 233 are provided on the outside of the telescopic bucket 231. The height of the ear plate 233 of each telescopic bucket 231 is higher than the height of the lifting ring 232. The lifting ring 232 on the outside of the front hopper 220 and the ear plate 233 of the uppermost telescopic bucket 231, as well as the lifting ring 232 on the outside of the previous telescopic bucket 231 and the ear plate 233 on the outside of the next telescopic bucket 231, are connected by springs 240. In use, the lowermost telescopic bucket 231 extends into the hopper of the pouring equipment 210 and is fixedly connected to the hopper of the pouring equipment 210 by a steel wire rope.

[0047] When the telescopic bucket mechanism 230 is not under force, under the action of the spring 240, the next telescopic bucket 231 extends upward to the outside of the previous telescopic bucket 231, and the telescopic bucket mechanism 230 shrinks to its minimum length.

[0048] The elastic force of the spring 240 keeps the telescopic bucket mechanism 230 at its minimum length when it is not under force. When the telescopic bucket mechanism 230 is connected to the hopper of the pouring equipment 210, it can adjust the height of the pouring equipment 210 without manual adjustment, thus achieving self-adaptive lifting and telescopic movement and ensuring continuous and uninterrupted concrete delivery.

[0049] The pouring equipment 210 is a pouring vehicle. In this embodiment, belt-driven or bucket-type pouring equipment such as tire-type, tracked, or non-mobile pouring vehicles can be selected.

[0050] A cable reel 700 is installed on the longitudinal beam 300 or the transverse beam 400 to reel in and unreel the control cable of the pouring equipment 200 according to the height of the lifting base plate 600. The cable reel 700 reels in and unreels the cable synchronously, avoiding tangling and pulling damage to the cable due to lifting or movement, eliminating the need for manual cable handling and reducing manual intervention.

[0051] Preferred, such as Figure 6 As shown, the lifting base plate 600 is a hollow steel structure. Telescopic plates 610 are provided at both ends of the lifting base plate 600, and the telescopic plates 610 are inserted into the cavity of the lifting base plate 600. A rack 620 is provided on the outer side of the telescopic plate 610. A motor 630 is installed inside the cavity of the lifting base plate 600, and a gear 640 that meshes with the rack 620 is provided on the shaft of the motor 630. Several limiting pulleys 650 are provided inside the cavity of the lifting base plate 600, and the limiting pulleys 650 are located on the upper and lower sides of the telescopic plate 610. The motor 630 drives the gear 640 to mesh with the rack 620, realizing the telescopic range of the telescopic plate 6100-2m. It can be used to connect concrete platforms with different height differences, avoiding the safety hazards of traditional scaffolding connections. The limiting pulleys 650 restrict the vertical displacement of the telescopic plate 610, ensuring precise telescopic direction.

[0052] The extended end of the telescopic plate 610 is provided with a ramp 611. The ramp 611 is designed to avoid steps at the extended end of the telescopic plate 610, prevent wheels from bumping into it, and ensure smooth passage of the equipment.

[0053] Example 2: Taking the construction of a large channel as an example, the channel is 10m wide, 100m long, and has a slope height of 8m. The multi-section lifting gantry continuous pouring equipment in Example 1 is operated.

[0054] (a) The pouring operation includes the following steps: Step 1: Pre-operation preparation: Check the status of the lifting mechanism 100 and the pouring system 200; drive the traveling wheels 120 to roll along the track 500 and transfer the equipment to the concrete platform where the pouring equipment 210 needs to be loaded; start the lifting drive motor 113 to drive the rotating shaft 112 inside the lifting column 110 to rotate. The spiral blades 114 on the rotating shaft 112 and the rollers 115 roll together, so that the slide rod 118 slides along the slide groove 119 and adjusts the height of the lifting base plate 600 to be level with the concrete platform.

[0055] Step 2: Telescopic Plate Overlap: Start the motor 630 inside the cavity of the lifting base plate 600. The motor 630 drives the gear 640 to rotate. The gear 640 meshes with the rack 620 on the outside of the telescopic plate 610, causing the telescopic plate 610 to extend out of the cavity of the lifting base plate 600. During the adjustment of the telescopic plate 610, several limiting pulleys 650 inside the cavity of the lifting base plate 600 roll against the upper and lower sides of the telescopic plate 610, guiding the telescopic direction of the telescopic plate 610 and limiting the vertical displacement of the telescopic plate 610. This ensures that the telescopic plate 610 is accurately overlapped with the concrete platform, so that the extended end of the telescopic plate 610 overlaps with the concrete platform, forming a passage for the equipment.

[0056] Step 3: Assembly of the pouring equipment: Move the pouring equipment 210 along the telescopic plate 610 to the lifting base plate 600, adjust the posture of the pouring equipment 210 and extend its outrigger cylinders to fix it; pull the telescopic bucket mechanism 230 to stretch the spring 240, and extend the lowermost telescopic bucket 231 into the hopper of the pouring equipment 210. Connect the lifting ring 232 on the outside of the telescopic bucket 231 to the connecting ring of the receiving hopper 211 of the pouring equipment 210 through the steel wire rope to fix the telescopic bucket mechanism 230 and the pouring equipment 210.

[0057] Step 4: Adjustment of pouring operation: Control the walking wheel 120 to move along the track 500 and transfer the equipment to the target pouring position; restart the lifting drive motor 113 and adjust the extension length of the lifting column 110 so that the pouring end of the pouring equipment 210 is aligned with the pouring position. During the process, the cable reel 700 will synchronously retract and extend the control cable of the pouring equipment 210 according to the height change of the lifting base plate 600.

[0058] Step 5: Continuous pouring: Supply concrete to the front hopper 220 of the pouring system 200. The concrete flows from the front hopper 220 into the telescopic hopper 231 of the telescopic hopper mechanism 230, and finally enters the hopper of the pouring equipment 210. Control the start of the pouring equipment 210 to transport the concrete to the pouring location until the pouring operation in that area is completed.

[0059] After all areas have been poured, stop supplying concrete to the forward hopper 220, control the pouring equipment 210 to retract the pouring components, and disconnect the wire rope connection between the telescopic bucket 231 and the hopper of the pouring equipment 210; start the lifting drive motor 113 to drive the lifting column 110 to retract to its minimum length, so that the lifting base plate 600 is lowered to the lowest position, and at the same time the cable reel 700 retracts the control cable of the pouring equipment 210; start the motor 630 to drive the gear 640 to rotate in the opposite direction, so that the telescopic plate 610 is retracted into the cavity of the lifting base plate 600; control the traveling wheels 120 to move along the track 500, park the equipment at the end of the track 500 or a preset safe area, and turn off the main power supply of the equipment.

[0060] (ii) When performing hoisting operations, steps 1-2 are the same as those for pouring operations, and steps 6-9 are performed simultaneously: Step 6: Move the crane along the telescopic plate 610 onto the lifting base plate 600. Extend the outrigger cylinders of the crane and fix them to the lifting base plate 600 to ensure the stability of the crane.

[0061] Step 7: Control the traveling wheels 120 to move along the track 500 to the location where the suspended object is stored, start the lifting drive motor 113 to adjust the height of the lifting column 110 so that the crane hook is aligned with the suspended object.

[0062] Step 8: Operate the crane to extend the boom, hook the load and lift it up, then retract the boom to place the load within a safe range of 600 degrees from the lifting platform.

[0063] Step 9: Move the mobile equipment to the target lifting position, adjust the height of the lifting column 110 to the preset lifting height, and extend the crane arm to lower the load to the target position to complete the lifting operation.

[0064] (iii) When unloading is performed, steps 1-2 are the same as those for pouring, and steps 10-12 are also performed simultaneously: Step 10: The forklift travels along the telescopic plate 610 to the lifting base plate 600, unloads the goods to be transported onto the load-bearing area of ​​the lifting base plate 600, and then the forklift exits along the telescopic plate 610.
