Description

Technical Field

[0001] This invention relates to the field of construction equipment for diaphragm wall components, and in particular to a hoisting posture adjustment device for diaphragm wall components and its adjustment method. Background Technology

[0002] With the rapid development of underground engineering projects such as urban rail transit, underground integrated pipe corridors, and basements of high-rise buildings, diaphragm walls have become the core structural form for underground engineering support and waterproofing due to their advantages such as high rigidity, good seepage prevention performance, and minimal impact on the surrounding environment. During the construction of diaphragm walls, the hoisting and precise installation of components such as steel cages are the key links that determine the quality of the project. Their installation accuracy directly affects the overall load-bearing capacity, seepage prevention effect, and construction efficiency of the diaphragm wall. Currently, the hoisting and installation of diaphragm wall components generally adopts the traditional model of "hoisting equipment + manual assisted positioning." This involves using cranes or other hoisting equipment to lift and transport the components to the area to be installed. Multiple operators then adjust the component's position around the installation area using ropes and crowbars to align it with the installation reference before lowering it into place. However, this traditional operating model has many insurmountable drawbacks in practical application, severely restricting the safety, efficiency, and quality of engineering construction. Specifically, diaphragm wall components are generally large and heavy. During hoisting, the components are susceptible to uncontrollable displacement such as swaying and rotation due to wind and vibrations from the hoisting equipment. When operators are assisting with positioning below or around the components, if the components accidentally shake or fall, it can easily cause crushing, impact, and other safety accidents, posing a significant threat to the personal safety of the operators. Furthermore, the confined space and complex environment of underground construction areas further exacerbate the safety hazards of manual assisted operations.

[0003] Therefore, it is necessary to provide a new hoisting posture adjustment device and adjustment method for diaphragm wall components to solve the above-mentioned technical problems. Summary of the Invention

[0008] Preferably, the end of the mounting cylinder away from the first positioning plate has a mounting groove, the inner wall of the mounting groove is fixedly connected to a spring two, the other end of the spring two is fixedly connected to a locking block, and the side wall of the slide rod has a locking groove that cooperates with the locking block.

[0009] Preferably, each of the card blocks has a protruding rod fixedly connected to the side near the second spring. The top of each protruding rod extends out of the top of the mounting cylinder, and a pull rod is fixedly connected between the tops of the two protruding rods. Each of the buffer plates has a guide rod fixedly connected symmetrically to the side near the bottom. The other end of each guide rod is placed inside the first positioning plate and is slidably connected to its inner wall.

[0010] Preferably, the bottom of the bearing plate is rotatably connected to a bidirectional screw and a limiting rod, and the bidirectional screw and the limiting rod are symmetrically arranged. The outer wall of the bidirectional screw is symmetrically threaded with a connecting rod. The other end of the connecting rod is sleeved on the outer wall of the limiting rod and slidably connected to it. The middle part of the connecting rod is fixedly connected to the corresponding second positioning plate. The two sides of the second positioning plate that are far apart from each other are symmetrically fixedly connected with reinforcing ribs, and the bottom end of the reinforcing ribs is slidably connected to the top of the bearing plate.

[0011] Preferably, a motor is fixedly connected to the top of the support plate, and a drive gear is fixedly connected to its output end. A driven gear is fixedly connected to the end of the bidirectional screw near the motor, and the drive gear and the driven gear mesh with each other.

[0012] Preferably, the adjustment assembly includes: motor two, gear one, and arc-shaped gear ring. Support rods are fixedly connected to the bottom circumference of the support plate at equal intervals. Arc-shaped grooves are opened at equal intervals on the inner circumference of the movable seat. The support rods are placed inside the corresponding arc-shaped grooves and are slidably connected to their inner walls. Motor two is fixedly connected inside the movable seat, and gear one is fixedly connected to its output end. Arc-shaped gear ring is fixedly connected to the bottom of the support plate, and gear one meshes with the arc-shaped gear ring. The center position of the arc-shaped gear ring is the same as that of the support plate.

[0013] Preferably, the top of the loading vehicle is symmetrically and fixedly connected with a slide block, the movable seat is placed on top of the slide block and slidably connected thereto, and a hydraulic push rod is fixedly connected inside the loading vehicle, the output end of which is fixedly connected to the movable seat.

[0014] A method for adjusting the hoisting posture of a diaphragm wall component includes the following steps: S1: Move the loader to the installation area, start the hydraulic push rod to drive the moving seat to coincide with the installation position, and start the motor to adjust the bearing plate to be aligned with the installation area; S2: Use hoisting equipment to lift the component to be installed and move it to the area above the support plate; S3: First, start the electric push rod to drive the first positioning plate to move closer to each other, so that the buffer plate contacts the side wall of the component, thereby locking the position of the buffer plate and the first positioning plate and positioning the component laterally. S4: When starting motor one, drive the second positioning plates to move closer to each other, so that the second positioning plates contact the side wall of the component and position the component longitudinally; S5: Start the hoisting equipment to install the components below. Under the limit of the first positioning plate and the second positioning plate, the components are smoothly installed into the installation area.

[0015] Compared with related technologies, the hoisting posture adjustment device and method for diaphragm wall components provided by the present invention have the following beneficial effects: By designing the positioning components, precise bidirectional positioning of the components is achieved in both the lateral and longitudinal directions. The electric push rod drives the first positioning plate to move smoothly along the slide rail, achieving precise lateral positioning of the components. The motor drives the bidirectional screw to rotate, driving the second positioning plate to complete the longitudinal centering positioning of the components. There is no need for operators to pull or pry around the components, which completely avoids the safety risks of crushing and impact caused by the shaking and falling of heavy components, and fundamentally protects the personal safety of construction personnel.

[0016] The design of the buffer plate utilizes the elastic deformation of the spring to buffer the positioning impact force, avoiding rigid contact that could cause component deformation or equipment damage, thus extending the service life of the device. When the slot and the block are precisely engaged, the position of the buffer plate and the first positioning plate is locked, ensuring positioning stability. After the operation is completed, pulling the lever unlocks the block, and the spring automatically pushes the buffer plate back to its original position, making the operation convenient.

[0017] The horizontal and vertical positioning of the positioning components can be completed in a short time, which greatly shortens the positioning time of a single component compared to the repeated calibration of manual positioning. At the same time, after positioning is completed, the component can be directly driven to be lowered and installed, reducing intermediate waiting links and significantly improving the overall efficiency of diaphragm wall construction.

[0018] The design of the adjustment components enables horizontal alignment and fine-tuning of the support plate. A hydraulic push rod drives the moving seat to move horizontally along the slide, aligning the support plate with the installation area. Motor 2 drives gear 1 to rotate, which in turn drives the support plate to rotate around its center via an arc-shaped gear ring, achieving fine-tuning of the angle. This dual adjustment function of horizontal and angular alignment precisely adapts to installation requirements at different positions and angles, improving the device's adaptability.

[0021] 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 merely illustrative and not intended to limit the invention.

[0022] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 8 A hoisting posture adjustment device and method for diaphragm wall components are disclosed. The hoisting posture adjustment device for diaphragm wall components includes: a loading vehicle 1, a buffer plate 4, a first positioning plate 5, a second positioning plate 6, a drive assembly, and an adjustment assembly. A movable seat 2 is installed on the top of the loading vehicle 1, and a bearing plate 3 is installed on the top of the movable seat 2. Buffer plates 4 are symmetrically arranged on the top of the bearing plate 3. A first positioning plate 5 is provided on each side of the buffer plates 4 that are far apart from each other. A second positioning plate 6 is provided at both ends of the buffer plates 4. A drive assembly is installed between the bearing plate 3 and the first positioning plate 5. The drive assembly drives the first positioning plates 5 to move closer together to position the hoisted component. An adjustment assembly is installed between the movable seat 2 and the bearing plate 3. The adjustment assembly drives the bearing plate 3 to move to center the installation area.

[0024] The drive assembly includes: an electric push rod 7, a slide rail 8, a connecting rod 9, and a guide rod 10. The top of the support plate 3 is symmetrically and fixedly connected to the electric push rod 7, and the output end of each push rod is fixedly connected to the corresponding first positioning plate 5. The top of the support plate 3 is symmetrically and fixedly connected to the slide rail 8. The two first positioning plates 5 are slidably connected to the corresponding slide rail 8. The side walls of the first positioning plates 5 are symmetrically and fixedly connected to the guide rod 10. The outer wall of the guide rod 10 is slidably fitted with a slider 11. The inside of the slider 11 is rotatably connected to the connecting rod 9. The other end of the connecting rod 9 is rotatably connected to the top of the support plate 3.

[0025] The first positioning plate 5 is symmetrically fixedly connected with mounting cylinders 12 inside each of the two buffer plates 4. The side walls of the two buffer plates 4 are symmetrically fixedly connected with sliding rods 13, and the sliding rods 13 are placed inside the corresponding mounting cylinders 12. The outer wall of the end of the sliding rod 13 away from the buffer plate 4 is fitted with a spring 14. One end of the spring 14 is fixedly connected to the outer wall of the sliding rod 13, and the other end is fixedly connected to the inner wall of the mounting cylinder 12.

[0026] The mounting cylinder 12 has mounting grooves at the end away from the first positioning plate 5. Spring 15 is fixedly connected to the inner wall of each mounting groove. A locking block 16 is fixedly connected to the other end of each spring 15. The side wall of the slide rod 13 has a locking groove 17 that cooperates with the locking block 16.

[0027] Each of the card blocks 16 has a protruding rod fixedly connected to the side near the second spring 15. The top of each protruding rod extends out of the top of the mounting cylinder 12, and a pull rod 18 is fixedly connected between the tops of the two protruding rods. Each of the buffer plates 4 has a guide rod 19 fixedly connected symmetrically to the side near the bottom. The other end of each guide rod 19 is placed inside the first positioning plate 5 and is slidably connected to its inner wall.

[0028] The bottom of the bearing plate 3 is rotatably connected to a bidirectional screw 20 and a limiting rod 21, and the bidirectional screw 20 and the limiting rod 21 are symmetrically arranged. The outer wall of the bidirectional screw 20 is symmetrically threaded with a connecting rod 22. The other end of the connecting rod 22 is sleeved on the outer wall of the limiting rod 21 and slidably connected to it. The middle part of the connecting rod 22 is fixedly connected to the corresponding second positioning plate 6. The two sides of the second positioning plate 6 that are far apart from each other are symmetrically fixedly connected with reinforcing ribs 26, and the bottom end of the reinforcing ribs 26 is slidably connected to the top end of the bearing plate 3.

[0029] A motor 23 is fixedly connected to the top of the bearing plate 3, and a drive gear 24 is fixedly connected to its output end. A driven gear 25 is fixedly connected to the end of the bidirectional screw 20 near the motor 23, and the drive gear 24 and the driven gear 25 mesh with each other.

[0030] When the buffer plate 4 contacts the side wall of the component, the slide rod 13 slides in the mounting cylinder 12, compressing the spring 14. The spring 14 acts as a buffer, reducing the impact force of the component on the buffer plate 4. At the same time, as the slide rod 13 slides, the locking block 16 is locked into the slot 17 on the side wall of the slide rod 13 under the action of the spring 2 15, realizing the position locking of the buffer plate 4 and the first positioning plate 5, ensuring the stable positioning of the component. The reinforcing rib 26 enhances the stability and structural strength of the second positioning plate 6 during movement, preventing the positioning plate from deforming due to stress.

[0031] Example 2 Please see Figure 2 , Figure 7 and Figure 8The adjustment assembly includes: motor 29, gear 30, and arc-shaped toothed ring 31. Support rods 27 are fixedly connected to the bottom circumference of the support plate 3 at equal intervals. Arc-shaped grooves 28 are opened at equal intervals on the inner circumference of the moving seat 2. The support rods 27 are placed inside the corresponding arc-shaped grooves 28 and are slidably connected to their inner walls. Motor 29 is fixedly connected to the inside of the moving seat 2, and gear 30 is fixedly connected to its output end. Arc-shaped toothed ring 31 is fixedly connected to the bottom of the support plate 3, and gear 30 and arc-shaped toothed ring 31 mesh with each other. The center position of arc-shaped toothed ring 31 is the same as that of the support plate 3.

[0032] The top of the loading vehicle 1 is symmetrically and fixedly connected with a slide block 32. The movable seat 2 is placed on the top of the slide block 32 and is slidably connected to it. The interior of the loading vehicle 1 is fixedly connected with a hydraulic push rod 33, the output end of which is fixedly connected to the movable seat 2.

[0033] When motor 29 starts, it drives gear 30 to rotate. Since gear 30 meshes with the arc-shaped gear ring 31, and the center of the arc-shaped gear ring 31 is the same as that of the support plate 3, the rotation of gear 30 will drive the arc-shaped gear ring 31 to rotate around the center, thereby driving the support plate 3 to rotate under the cooperation of support rod 27 and arc-shaped groove 28, realizing the centering adjustment of the support plate 3 and the area to be installed. This design makes the rotation adjustment of the support plate 3 more stable and accurate.

[0034] A method for adjusting the hoisting posture of a diaphragm wall component includes the following steps: S1: Move the loader 1 to the installation area, start the hydraulic push rod 33 to drive the moving seat 2 to coincide with the installation position, and start the motor 29 to adjust the bearing plate 3 to be aligned with the installation area; S2: Use hoisting equipment to lift the component to be installed and move it to the area above the support plate 3; S3: First, start the electric push rod 7 to drive the first positioning plate 5 to move closer to each other, so that the buffer plate 4 contacts the side wall of the component, thereby locking the position of the buffer plate 4 and the first positioning plate 5, and positioning the component laterally. S4: When starting motor 23, drive the second positioning plate 6 to move closer to each other, so that the second positioning plate 6 contacts the side wall of the component and positions the component longitudinally. S5: Start the hoisting equipment to install the component below. Under the limit of the first positioning plate 5 and the second positioning plate 6, the component is smoothly installed into the installation area.

[0035] The working principle of the diaphragm wall component hoisting attitude adjustment device provided by the present invention is as follows: Move the loader 1 to the installation area and park it according to the site baseline, ensuring that the loader 1 body is roughly parallel to the installation area to lay the foundation for precise alignment later. Activate the hydraulic push rod 33 inside the loader 1. The output end of the hydraulic push rod 33 drives the movable seat 2 to move horizontally along the sliding seat 32 symmetrically fixed on the top of the loader 1. By observing the position of the movable seat 2, when the movable seat 2 moves the upper bearing plate 3 to coincide with the installation position, close the hydraulic push rod 33 to complete the initial horizontal alignment. Activate the second motor 29 inside the movable seat 2. The output end of the second motor 29 drives the first gear 30 to rotate. Because the first gear 30... The gear 0 meshes with the arc-shaped toothed ring 31 fixed at the bottom of the support plate 3, and the arc-shaped toothed ring 31 is at the same position as the center of the support plate 3. The rotation of gear 1 30 will drive the arc-shaped toothed ring 31 to rotate synchronously, thereby driving the support plate 3 to rotate around the center. During this process, the support rods 27 fixed at equal intervals around the bottom of the support plate 3 slide synchronously in the arc-shaped groove 28 inside the moving seat 2, providing guidance and support for the rotation of the support plate 3 and avoiding tilting or offset during the rotation. When it is observed that the area on the top of the support plate 3 used to support the component is completely aligned with the area to be installed, the motor 29 is turned off. At this time, the position of the support plate 3 is completely fixed, and the posture alignment is completed. Start the external hoisting equipment and lift the diaphragm wall component to be installed smoothly; the operators work together to control the hoisting equipment and transfer the component to the area above the already aligned bearing plate 3, ensuring that the center of gravity of the component is roughly aligned with the center of the bearing plate 3; Slowly lower the component using the hoisting equipment, gradually bringing the bottom of the component into the area enclosed by the first positioning plate 5 and the second positioning plate 6. Then pause the lowering action of the hoisting equipment to prepare for subsequent positioning adjustments. Start the electric push rods 7 that are symmetrically fixed on the top of the bearing plate 3. The output end of the electric push rods 7 extends synchronously, driving the corresponding first positioning plate 5 to move smoothly along the slide rail 8 towards the component. At the same time, the first positioning plate 5 drives the inner buffer plate 4 to move closer to the component. During the movement of the first positioning plate 5, the connecting rod 9 rotates around the rotational connection point with the bearing plate 3, while simultaneously driving the slider 11 to slide downwards along the guide rod 10 axially; this enhances the stability of the movement of the first positioning plate 5, ensuring that the two positioning plates approach each other synchronously and are subjected to uniform force; when the buffer plate 4 contacts the side wall of the component, the component generates a reverse compressive force on the buffer plate 4, pushing the sliding rod 13, which is symmetrically fixed to the side wall of the buffer plate 4, to retract into the mounting cylinder 12 inside the first positioning plate 5, while the guide rod 19 near the bottom of the buffer plate 4 also slides into the first positioning plate 5; the sliding rod 1 3. During the contraction process, the spring 14 sleeved on its outer wall is compressed. The elastic deformation of the spring 14 can effectively buffer the impact force of the component on the first positioning plate 5 and avoid damage to the equipment caused by rigid contact. As the electric push rod 7 continues to extend slowly, the slide rod 13 continues to retract. When the slot 17 opened on the side wall of the slide rod 13 moves to correspond to the position of the locking block 16 in the mounting cylinder 12, the spring 15 in the mounting slot releases its elastic force, pushes the locking block 16 to move towards the slot 17 and precisely engages with the slot 17, thereby locking the position of the buffer plate 4 and the first positioning plate 5. The electric push rod 7 continues to output force until the component is laterally positioned in the corresponding position of the preset installation area. At this time, the buffer plates 4 on both sides are in contact with the side wall of the component, realizing the precise lateral positioning of the component. The electric push rod 7 is turned off, and the lateral positioning is completed. Next, the motor 23 on the top of the support plate 3 is started, and the output end of the motor 23 drives the drive gear 24 to rotate. Since the drive gear 24 meshes with the driven gear 25 near the end of the bidirectional screw 20 close to the motor 23, the rotation of the drive gear 24 drives the driven gear 25 to rotate synchronously, thereby driving the bidirectional screw 20 to rotate around its own axis. When the bidirectional screw 20 rotates, the connecting rod 22 with symmetrical threaded connection on its outer wall cannot rotate with the screw due to the guidance restriction of the limiting rod 21, and can only move synchronously towards the middle along the axial direction of the limiting rod 21. The middle part of the connecting rod 22 is fixedly connected to the second positioning plate 6, so it will drive the second positioning plates 6 on both sides to move synchronously towards the component direction. During this process, the bottom ends of the reinforcing ribs 26 that are symmetrically fixed away from each other on one side of the second positioning plate 6 slide along the top of the support plate 3, which enhances the stability and structural strength of the movement of the second positioning plate 6 and avoids the positioning plate from deforming due to force. As the second positioning plate 6 continues to approach and gradually contacts the longitudinal sidewall of the component, the motor 23 continues to run until the second positioning plate 6 longitudinally positions the component at the center of the bearing plate 3. At this time, the motor 23 stops outputting power to ensure that the first positioning plate 5 and the second positioning plate 6 only contact the sidewall of the component, providing a limiting effect and not generating clamping force to avoid affecting the subsequent components below. The longitudinal positioning is then completed. Start the hoisting equipment and continue to slowly lower the component. Because the component is precisely limited by the positioning plate in both the horizontal and vertical directions, its posture remains stable during the lowering process and it will not swing or deviate. The component gradually approaches the installation area along the trajectory defined by the positioning plate until the bottom of the component is precisely attached to the installation reference surface. After the operator confirms that the component is completely aligned with the installation area, the installation and fixing of the component is completed. After the components are installed, the starter motor 23 reverses, driving the drive gear 24 and driven gear 25 to rotate in the opposite direction, which in turn drives the bidirectional screw 20 to rotate in the opposite direction; the connecting rod 22 moves to both sides along the axial direction of the limiting rod 21, driving the second positioning plate 6 to open and reset synchronously; The electric push rod 7 is activated to retract, causing the first positioning plate 5 to move and reset along the slide rail 8 to both sides. Then, the operator pulls the pull rod 18 upward. The two ends of the pull rod 18 are fixedly connected to the locking block 16 through the protrusions. Pulling the protrusions causes the locking block 16 to move upward, compressing the second spring 15 and disengaging it from the slot 17 on the side wall of the slide rod 13, thus releasing the position lock between the buffer plate 4 and the first positioning plate 5. At this time, the first spring 14 releases its elastic force, pushing the slide rod 13 to move in the opposite direction, causing the buffer plate 4 to reset, and the guide rod 19 to extend and reset simultaneously. If the installation of the next component is required, the above steps are repeated. If the operation is completed, all components of the device are reset to their initial state, and the loading vehicle 1 leaves the work area to complete the operation.
