Description

Technical Field

[0001] This invention belongs to the technical field of concrete pouring equipment, specifically relating to a casing loading and unloading device for ultra-deep seepage-proof wall concrete pouring. Background Technology

[0002] In existing concrete grouting processes, after excavating a trench in the ground, concrete is continuously poured into the trench. The grouting method involves inserting a sleeve into the trench from the ground, injecting concrete into the sleeve, and allowing the concrete to flow downwards along the sleeve and fall out from the bottom end of the sleeve. Because the trench has a certain depth, the sleeve needs to be continuously pulled upwards during the grouting process to ensure that the concrete overflow resistance at its lower end remains within a small range. The current method involves using a winch to pull the entire upper end of the sleeve, and then having multiple people operate on the ground to continuously pull the sleeve, which is composed of sections of pipe, out of the ground and disassemble it in a timely manner. Similarly, during installation and placement, winches or other lifting equipment are also needed to continuously install and release the heavy sleeve.

[0003] The aforementioned manual lifting and disassembly operations for the casing, performed with the assistance of lifting equipment, are complex, consume significant manpower and resources, and are inefficient. Furthermore, the disassembled casing cannot be moved promptly, and its surface and interior contain a large amount of sticky concrete, requiring immediate cleaning before storage; otherwise, it will harden and adhere to the surface, making it difficult to remove. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides a casing loading and unloading device for ultra-deep seepage-proof wall concrete pouring. Through multiple functional modules, it can automatically disassemble, clean, and store the casing used for concrete pouring, thereby improving efficiency.

The sleeve is hoisted by detachably connecting at least one connecting part to the sleeve, and the sleeve is disassembled and assembled by connecting at least two connecting parts to different pipe bodies that rotate relative to each other around the axis of the sleeve.

[0008] The placement section has a tube rack for placing a number of tubes, and a transfer device provided in the placement section transfers the tubes between the cleaning section and the tube rack.

[0009] A loading and unloading frame is provided between the hoisting section and the placement section. After the two connecting sections disassemble the pipe body, the loading and unloading frame transfers the disassembled pipe body to the fixed frame, and the transfer device transfers the pipe body on the fixed frame to the placement section or the cleaning section.

[0010] It should be noted that this equipment is not only used to disassemble and place the assembled sleeves inserted into the ground, but also to transfer the pipes in the pipe rack to the hoisting part for assembly.

[0012] When the loading and unloading frame rotates until the upright frame remains parallel, the supply pipe is transferred between the loading and unloading frame and the upright frame.

[0013] When the loading and unloading frame and the fixed frame are kept parallel, the supply pipe is transferred between the loading and unloading frame and the transfer device.

[0014] In conjunction with the first embodiment of the first aspect, the present invention provides a second embodiment of the first aspect, wherein the upright is a portal frame structure, including two uprights and a crossbar provided at the top of the uprights for connection, and the loading and unloading frame is rotated to be parallel to the uprights and is located in the gap area between the two uprights.

[0015] In conjunction with the first embodiment of the first aspect, the present invention provides a third embodiment of the first aspect, wherein the loading and unloading frame is provided with a support frame and a hook, the support frame has an arc-shaped contact surface that fits against the outer surface of the tube body, and when the tube body is placed on the support frame and fits against the arc-shaped contact surface, the hook portion that is movably connected to the loading and unloading frame presses the tube body against the support frame.

[0016] In conjunction with the third embodiment of the first aspect, the present invention provides a fourth embodiment of the first aspect, wherein the hook is displaced by a hydraulic rod or a motor mounted on the loading and unloading frame.

[0017] In conjunction with the first aspect or several embodiments of the first aspect, the present invention provides a fifth embodiment of the first aspect, wherein the sleeve is displaced relative to the fixed frame along the length direction of the upright, the upright is provided with a lifting frame driven by a lifting mechanism, one connecting part is a disassembly device provided on the lifting frame, and the other connecting part is a clamping device provided on the fixed frame.

[0018] The clamping device limits the sleeve passing through the fixed frame, and the disassembly device is detachably connected to the sleeve for lifting;

[0019] The disassembly device has a bushing that is rotatably connected to the lifting frame. The bushing is rotated by the disassembly motor, and the disassembly device and the clamping device are respectively connected to two adjacent pipes and rotate around the pipe axis for disassembly.

[0020] In conjunction with the first aspect or several embodiments of the first aspect, the present invention provides a sixth embodiment of the first aspect, wherein the pipe rack has several vertically arranged placement slots, and several pipes are stacked in the placement slots.

[0021] In conjunction with the first aspect or several embodiments of the first aspect, the present invention provides a seventh embodiment of the first aspect, wherein the cleaning unit includes a rinsing rack for placing at least a single pipe body, and a baffle disposed between the rinsing rack and the pipe rack, wherein the rinsing rack is provided with a rotating mechanism for driving the pipe body to rotate, and the pipe body placed on the rinsing rack is rinsed by a rinsing mechanism disposed on a fixed frame or externally.

[0022] In conjunction with the first aspect or several embodiments of the first aspect, the present invention provides an eighth embodiment of the first aspect, wherein the transfer device includes a sliding frame that slides along a slide rail provided on a fixed frame, and a truss provided on the top of the sliding frame, wherein a track is provided inside the truss for a hanger provided on the truss to limit the movement, and the hanger has a vertical lifting device for clamping and transferring the tube body.

[0023] In conjunction with the eighth embodiment of the first aspect, the present invention provides a ninth embodiment of the first aspect, wherein the lifting device includes a fixed base and clamping arms symmetrically hinged on both sides of the fixed base, the two clamping arms are hinged and pushed by the same hydraulic rod provided on the fixed base, and the ends of the two clamping arms away from the hinge point with the fixed base clamp the outer wall of the pipe body; at least two lifting devices are provided on the same hanger.

[0024] The beneficial effects of this invention are as follows:

[0025] (1) The present invention uses a lifting unit to lift and disassemble the entire casing. It can not only lift and disassemble the casing while it is being poured with concrete, but also install and release the pipe sections before grouting and insert them into the ground. Compared with manual pipe disassembly and installation, it can improve efficiency, reduce costs, and avoid the inconvenience caused by manual handling in complex working conditions.

[0026] (2) By setting the placement part and the cleaning part on the same fixed frame, the present invention can clean and place the disassembled tubes after the transfer device is placed, thereby reducing manual labor and improving efficiency.

[0027] (3) The present invention uses a loading and unloading frame structure set by the cooperative support frame to support the vertically moving sleeve during disassembly and assembly at the hoisting part. At the same time, during disassembly, the removed pipe can be guided to one side and transferred out of the support frame so that it can be grabbed by the transfer device. During installation, the pipe transported from the transfer device can be sent into the support frame and grabbed by the connection part of the support frame for installation. The structure is simple and efficient.

[0028] (4) The present invention uses a cleaning section to rotate and clean one or more pipes, thereby avoiding the failure of the removed pipes to be cleaned in time, which would cause the concrete to solidify and affect the use of the pipes. Attached Figure Description

Detailed Implementation

[0038] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] Example 1:

[0046] This embodiment discloses a casing loading and unloading device for ultra-deep seepage-proof wall concrete pouring, which is used to disassemble and assemble the casing used for pouring concrete during the seepage-proof wall grouting process, thereby improving efficiency and saving labor.

[0047] The construction steps for the anti-seepage wall are as follows:

[0048] Drilling, cleaning and slurry replacement, final drilling and cleaning acceptance, pouring concrete under the mud slurry, quality inspection and acceptance of the entire wall, and handling the connection with the seepage prevention body inside the dam.

[0049] Drilling is carried out using impact drilling rigs, rotary drilling rigs, milling drills, or hydraulic grab buckets and scraper buckets. Bentonite or high-quality clay is used to prepare drilling mud, which is used to stabilize the borehole walls, suspend and carry rock cuttings, cool and lubricate the drill bit. The quality of the drilling mud directly affects the progress, quality, and safety of the drilling process. Hole cleaning and mud replacement involves replacing the drilling mud containing a large amount of sand and rock cuttings with qualified drilling mud. It also involves cleaning the rock cuttings and mud cake adhering to the concrete surfaces at both ends of the borehole to ensure the quality of the concrete wall, the vertical joints between adjacent wall sections, and the contact zone between the wall bottom and the bedrock.

[0050] During pouring, a sleeve is used. The sleeve is a standard grouting device, formed by assembling and connecting several identical pipe bodies 3. The number of pipe bodies 3 in the sleeve is determined according to the usage requirements. Each pipe body 3 has a female head and a male head, which are connected by threads. The female head has a groove or a multi-tooth structure similar to a spline on the outside to facilitate the locking and positioning of external connection structures. In this embodiment, the sleeve structure is not limited, and it has common design features known to those skilled in the art as existing technology.

[0051] Because the equipment involves disassembling and assembling the casing before or during concrete pouring, especially during disassembly, the outer surface of the disassembled pipe body 3 is covered with a large amount of mud, and the inner surface is covered with concrete. If it is directly piled up, it will affect the next use. Therefore, it needs to be cleaned in time before placement. In the existing technology, cleaning equipment is usually set up next to the hoisting equipment and operated manually. However, due to the troublesome transportation and transfer, multiple cranes are required to work together, resulting in low operating efficiency.

[0052] Meanwhile, the entire device is directly or indirectly set on the ground. Although the ground or other fixed surfaces are not shown in the figures of this embodiment, it can be assumed that the entire device is viewed as a whole and remains stationary relative to the ground. The sleeve, as a strip structure inserted into the ground, will move relative to the device. The following technical features will describe their relative positional relationships with the sleeve as a reference.

[0053] Specifically, the loading and unloading equipment in this embodiment refers to... Figures 1-8It includes a fixed frame 1 and several functional parts set on the fixed frame 1. The fixed frame 1 is a frame structure formed by riveting and bolting strip metal profiles such as I-beams or channel steel. It has several connecting rods inside for structural reinforcement, while the several functional parts have independent structures and are fixed to the metal profiles of the fixed frame 1 by bolts or other means.

[0054] Among them, reference Figure 1 The functional units, from left to right, include a hoisting unit, a placement unit, and a cleaning unit. The fixed frame 1 is equipped with a movable transfer device, which transports the tube 3 between the placement unit and the cleaning unit.

[0055] The hoisting unit has a frame 2, and the sleeve passes through one side of the frame 2 in a vertical direction and is displaced along the length of the frame 2. The hoisting unit has at least two connecting parts arranged along the axis of the sleeve, and hoisting is performed by detachably connecting at least one connecting part to the sleeve. The sleeve is disassembled and assembled by connecting at least two different pipe bodies 3 to rotate relative to each other around the axis of the sleeve.

[0056] Meanwhile, during the disassembly and assembly process, due to the threaded assembly relationship, once both connecting parts are fixedly connected to the sleeve, the speed difference generated by the two connecting parts around the axis alone is theoretically insufficient to split the tube into three parts. Therefore, it is necessary to control the two connecting parts to make linear displacement in the axial direction by coordinating the speed difference, so as to meet the conditions for threaded disassembly.

[0057] The hoisting unit also has a loading and unloading frame 5, which transports the pipe body 3 between the fixed frame 1 and the hoisting unit, and loads and unloads the pipe body 3 from the fixed frame 1 or the loading and unloading frame 5 in conjunction with the transfer device.

[0058] The placement section has a pipe rack 7 for placing several pipe bodies 3, and the transfer device has a lifting device 9 for transferring the pipe bodies 3 from the pipe rack 7. The pipe bodies 3 are transferred to the cleaning section by the lifting device 9, where they are rinsed internally and externally by an external rinsing mechanism. After rinsing, the pipe bodies 3 are put back by the transfer device.

[0059] It should be noted that the entire device has an electrical control module, specifically a common industrial PLC controller. Through simple embedded program settings, based on known parameters such as rotational speed and minimum lifting adjustment rate, it can perform disassembly and assembly operations automatically. The aforementioned automatic control technology based on program settings is obvious to those skilled in the art and presents no implementation obstacles. This embodiment only limits its structure and relative positional relationships.

[0060] Specifically, refer to Figure 4 This shows the relative positions of the functional parts of the device.

[0061] The upright 2 is a portal frame structure with two uprights and a top connecting crossbar. A sliding lifting frame 11 is mounted on the upright 2. The lifting frame 11 is a single-plate structure with corresponding sliders on its two sides. The sliders achieve a limiting linear sliding connection by embedding or sleeved with the uprights, and the uprights provide a limiting effect for the lifting frame 11.

[0062] A lifting mechanism is provided between the lifting frame 11 and the upright frame 2. The lifting mechanism is controlled by the control module to provide power to the lifting frame 11. In this embodiment, the lifting mechanism includes three types: Figure 4 The winch 12 shown is mounted on the horizontal bar, and a chain lifting mechanism and a hydraulic lifting mechanism are also installed in the hollow part inside the vertical bar. Theoretically, to cope with casing structures of different masses and lengths, corresponding lifting mechanisms can be set according to requirements. This embodiment illustrates the application in an ultra-deep concrete pouring project. To cope with such a large-mass casing structure, the coordinated action of the above three lifting mechanisms can stably hoist or release the casing of the entire length.

[0063] It should be noted that the principles of the three lifting mechanisms are all existing technologies. They are all set on the fixed system formed by the upright 2 and the fixed frame 1, and their movable ends act on the lifting frame 11. Through the control module, the lifting is debugged in the early stage according to the known equipment parameters. Those skilled in the art can coordinate the three lifting mechanisms to control the lifting of the same lifting frame 11. This embodiment does not limit its specific structure and principle. Other mechanical devices that achieve the same function in the prior art can also be applied to provide lifting control for the lifting frame 11.

[0064] Furthermore, two additional I-beams are provided at the lower part of the support frame 2, thereby forming a gap for the sleeve to pass through. The two I-beams are fixed to the fixing frame 1 for mounting the clamping device 17 as a connection part.

[0065] A disassembly device 4, which serves as a connecting part, is provided on the lifting frame 11. The sleeve is disassembled and assembled through the joint cooperation of the disassembly device 4 and the clamping device 17.

[0066] Figure 4 The diagram only shows the sleeve structure formed by two pipes 3. The pipe 3 on the support 2 has been separated from the other pipe 3. In this embodiment, the principle is explained by the process of disassembling the sleeve, as follows:

[0067] During disassembly, the casing itself is in the process of concrete pouring. It is continuously lifted upwards according to the pouring requirements. After the upper end of the casing is raised to a certain height above the ground, one of the top pipe sections 3 needs to be removed. In the initial state, it is held in place by the clamping device 17 as follows... Figure 4In the state shown, after the sleeve passes through the gap between the clamping devices 17, the annular flange on its outer surface is located at the upper part of the clamping device 17. At this time, the clamps of the clamping device 17, which are driven by hydraulic rods, abut against each other, thereby clamping the outer wall of the sleeve from both sides. The annular flange at the upper part can abut against the upper surface of the clamp, providing a vertical support and limiting effect not only by the clamping and limiting effect of the clamp, but also by the snap-fit ​​method.

[0068] The sleeve is kept stable by the clamping device 17, and then the lifting frame 11 moves downward to the corresponding position, causing the disassembly device 4 to engage with the port connection at the top of the sleeve. The disassembly device 4 has a bushing with a disassembly motor on its outside. The disassembly motor drives the bushing to rotate, and the bushing itself also has a movable connection structure for connecting to the end of the tube body 3. Once the bushing is connected to the end of the sleeve, the clamping device 17 is released, and the lifting frame 11 provides support for the entire sleeve, which is then steadily lifted upwards by the lifting mechanism.

[0069] Once the tube is lifted to a certain height, that is, after the entire tube 3 passes through the clamping device 17 and the annular flange of the next adjacent tube 3 passes through the clamping device 17, the clamping device 17 clamps the sleeve again for fixation.

[0070] The sleeve of the disassembly device 4 is not disconnected from the tube. The disassembly motor drives the sleeve to rotate around the axis, causing the tube body 3 on the stand 2 and the lower tube body 3 fixed by the clamping device 17 to circumferentially move, thus loosening the threaded connection. During this process, the lifting mechanism adjusts the lifting speed to cooperate with the disassembly device 4 to unscrew the tube body 3 upwards, finally forming... Figures 1-4 The state in.

[0071] Furthermore, a certain gap exists between the hoisting section of the fixing frame 1 and the pipe rack 7, allowing the loading and unloading frame 5 to transfer the pipe body 3. (Refer to...) Figure 5 The loading and unloading frame 5 is also a plate frame structure composed of I-beams, initially parallel to the upright frame 2 and in an upright state. The lower end of the loading and unloading frame 5 is hinged to the fixed frame 1, and a hydraulic rod or motor unit is provided on the fixed frame 1 to drive its rotation.

[0072] Reference Figure 4 The loading and unloading frame 5 is equipped with a support frame 16, which has two independent arc-shaped contact surfaces, specifically two arc-shaped plates supported by a tripod. The curvature of the support frame 16 is similar to that of the outer surface of the tube body 3, allowing the tube body 3 to fit snugly against the arc-shaped contact surfaces.

[0073] Meanwhile, a hook 15, a semi-circular rod, is also provided on the loading and unloading frame 5. One end of the hook 15 is hinged to the loading and unloading frame 5, specifically to a tripod with a fixed arc-shaped contact surface, and is rotated by a hydraulic rod on the loading and unloading frame 5. When the hook 15 is open, the tube 3 can pass through and fit against the arc-shaped contact surface. When disassembling the tube 3, the arc-shaped contact surface can provide a certain limiting support effect for the tube 3 located on the upright frame 2. At this time, the hook 15 can be appropriately tightened to fit the tube 3 against the two arc-shaped contact surfaces. The arc-shaped contact surfaces can be provided with a rolling structure so that the rotation of the tube 3 is not affected when it is disassembled.

[0074] When transfer is required, the hook 15 is driven by the hydraulic rod to contact the surface of the tube body 3 and push it against the arc-shaped contact surface. At this time, the tube body 3 is clamped by the loading and unloading frame 5. Then, the hydraulic rod on the fixed frame 1 drives the loading and unloading frame 5 to rotate from the vertical position to the horizontal position, and finally refers to... Figure 7 and Figure 8 The loading and unloading rack is in state 5. At this time, the pipe body 3 is placed horizontally, and then clamped and lifted by the transfer device and sent to the cleaning section for cleaning.

[0075] It should be noted that the diagram only shows the relative positions of the components; the specific dimensions and shapes are not limited. For example, in the horizontal loading and unloading rack 5, a section of the tube 3 remains on the upright 2, which, as shown in the diagram, will affect the lifting and lowering of the sleeve. In actual use, the loading and unloading rack 5 also has a telescopic structure, which can move the tube 3 removed from the upright 2 towards the tube rack 7, leaving space for the sleeve to move around at the upright 2. When transferring the tube 3, the sleeve can be further lifted and disassembled through the two connecting parts.

[0076] Furthermore, the transfer device includes a sliding frame 10 that slides along a slide rail 6 provided on the fixed frame 1, and a truss 8 provided on top of the sliding frame 10. The truss 8 has a track inside for a hanger mounted on the truss 8 to limit its movement. The hanger has a vertically lifting device 9, which clamps and transfers the tube 3.

[0077] Reference Figure 7 The lifting device 9 includes a fixed base and clamping arms symmetrically hinged on both sides of the fixed base. The two clamping arms are hinged and pushed by the same hydraulic rod provided on the fixed base. The ends of the two clamping arms away from the hinge point with the fixed base clamp the outer wall of the pipe body 3. At least two lifting devices 9 are provided on the same hanger.

[0078] The cleaning section includes a rinsing rack 13 for placing at least a single pipe 3, and a baffle 14 disposed between the rinsing rack 13 and the pipe rack 7. The rinsing rack 13 is provided with a rotating mechanism that drives the pipe 3 to rotate. The rinsing mechanism disposed on the fixed frame 1 or externally sprays water to rinse the pipe 3 placed on the rinsing rack 13.

[0079] The pipe rack 7 has several vertically arranged placement slots, in which several pipes 3 are stacked. The two clamping arms of the lifting device 9 have small cross-sectional dimensions and long lengths. There is a certain gap between each placement slot, that is, after the pipes 3 are stacked in the figure, there is a gap between adjacent pipes 3 in the horizontal direction, which makes it convenient for the clamping arms to extend into the gaps to clamp the pipe 3 in the middle and lift it upward.

[0080] In practical use, anti-slip rubber blocks can be provided on the inner side of the clamping arm, or other structures that increase friction can be set to improve its clamping stability.

[0081] It should be noted that the motors, hydraulic rods, tracks, and other structures mentioned in this embodiment are all existing technologies. That is, it is sufficient to use a common structure to achieve its movement control. There are no limitations on its structure and principle, only on its setting position and connection relationship.

[0082] It should also be noted that there are multiple ways to provide power. For example, the sliding control of the sliding frame 10 can be achieved by a screw structure, belt transmission structure, gear belt structure, roller structure, and traction motor mounted on the fixed frame 1. The hanger mounted on the truss 8 can also be controlled by a screw structure, belt transmission structure, gear belt structure, roller structure, and traction motor. The flushing frame 13 can be rotated by a rotating structure with gap adjustment function, or by a roller structure externally attached to the surface of the pipe body 3. The flushing mechanism can be directly mounted on the fixed frame 1, including the pump piping assembly, which increases the water in the water source and sprays it out for flushing.

[0083] This invention is not limited to the optional embodiments described above, and anyone can derive other various forms of products based on the inspiration of this invention. The specific embodiments described above should not be construed as limiting the scope of protection of this invention; the scope of protection of this invention should be determined by the claims, and the specification can be used to interpret the claims.
