Description

Technical Field

[0001] The utility model relates to the field of building construction, and more specifically, to an integrated platform for caisson construction equipment. Background Art

[0002] Currently, the traditional method for constructing bridge anchor caissons primarily involves a combination of a traveling tower crane, flipping formwork, and a gantry crane. The caisson concrete structure is constructed using a flipping process. During each caisson section, operators stand on a cantilevered construction platform to tie and connect vertical rebar and install embedded parts. After the rebar binding is inspected and concealed, the caisson formwork is installed and reinforced manually using a tower crane. Concrete is then poured using a truck-mounted pump. Once the concrete reaches sufficient strength, the tower crane is used to flip the formwork and cantilevered construction platform over to the next wall section, completing the construction of each structural section.

[0003] In order to move the mud pump pipe in the caisson, a gantry crane needs to be installed on the top of each caisson grid. After the construction of each structural section is completed, the gantry crane leg track is installed on the top of the caisson concrete structure. The gantry crane can slide horizontally on the travel track. The sliding of the gantry crane drives the vertical mud suction pump pipe to pump out the mud in the caisson. The horizontal mud pumping pipe is placed on the cantilevered construction platform.

[0004] Each time the caisson is sunk and the caisson concrete structure is constructed, the gantry crane on the top of the caisson structure needs to be moved outside the safe range of the caisson. After the caisson is sunk into place or the structure construction is completed, the gantry crane is moved back to the top of the caisson concrete structure. Due to the influence of site conditions, the number of gantry cranes, the installation and removal method of the driving track, etc., the installation and removal time of the gantry crane each time is one month, which greatly increases the overall construction period of the caisson. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide an integrated platform for caisson construction equipment, which can effectively improve the efficiency of caisson construction, has strong turnover, and saves the overall construction period.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: constructing an integrated platform for caisson construction equipment, including a supporting column, a steel platform, a lower hanging frame, a hanging seat, a one-way self-locking clamp, a shoulder pole, a hook, a climbing rod, a steel formwork and a hydraulic cylinder, wherein the hanging seat is fixed to the caisson concrete structure by attachment, the one-way self-locking clamp is connected to the hanging seat through the shoulder pole, the supporting column is connected to the hanging seat, the top of the supporting column is fixedly connected to the steel platform, the supporting column is provided with a window hole for climbing in cooperation with the hook of the hanging seat, the hydraulic cylinder is installed on the bottom crossbeam of the supporting column, the climbing rod is arranged on the bottom crossbeam of the supporting column and connected to the one-way self-locking clamp on the hanging seat, the lower hanging frame is hung on the bottom of the steel platform through the hanging rod, and the steel formwork is hung on the lower part of the steel platform through a chain;

[0007] When the hydraulic cylinder is extended, the support column is pushed back to rise, and the support column disengages the hook claw. The beam transfers the downward force it receives to the climbing rod, and then to the shoulder pole and the hanger, and finally transfers the force to the concrete structure of the caisson. After the hydraulic cylinder pushes the support column back to rise a stroke, the hook claw supports the support column again, and the hydraulic cylinder is retracted to achieve a rise of the crossbeam and the climbing rod. The above steps are repeated, and the hydraulic cylinder is used to rise by multiple small strokes to achieve the jacking of the support column to complete the predetermined total stroke.

[0008] In the above scheme, a rotatable hook is provided on the hanging seat, and a plurality of blocks cooperating with the hook are provided on the supporting column. The hook is stuck under the block to prevent the supporting column from falling. When the supporting column is lifted, the block above the hook is disengaged from it, and when the block below the hook moves upward to contact the hook, the hook rotates under the action of the block. When the block moves up to above the hook, the hook returns to its initial position and the hook blocks the block above.

[0009] The above solution also includes a winch, which is suspended below the steel platform through a truss.

[0010] The above solution also includes a material placing machine, which is placed on a sliding support on the top of the steel platform.

[0011] In the above solution, the hanger is attached to the caisson concrete structure through a rotatable screw.

[0012] In the above solution, the top of the supporting column and the steel platform are connected with high-strength bolts.

[0013] In the above solution, the lower hanging frame is provided with a walkway plate and a flap.

[0014] In the above solution, the steel platform is composed of Bailey plates.

[0015] The implementation of the integrated platform for caisson construction equipment of the present utility model has the following beneficial effects:

[0016] 1. This new model uses the caisson concrete structure as an attachment fulcrum. The platform moves upward as a whole, driving the vertical steel formwork upward. This eliminates the need for tower cranes and other equipment, avoiding on-site disassembly and assembly operations. This saves labor while improving the appearance quality of the concrete. The steel formwork system is suspended from the lower part of the steel platform by chains, greatly reducing on-site manual installation and disassembly work.

[0017] 2. The utility model adopts a movable truss and winch to completely replace the gantry crane to move the mud pump and mud discharge pipe in the caisson, avoiding the influence of the gantry crane track on the construction of the caisson concrete structure and greatly shortening the installation and disassembly period of the gantry crane;

[0018] 3. The top of the utility model is a truss platform connected by longitudinal and transverse Bailey plates, which not only enhances the overall safety of the structure but also provides a valuable aerial work platform and a platform for the integration of the crane system, the hanging system, the steel formwork and the placing machine;

[0019] 4. The utility model matches the vertical reinforcement → formwork → concrete → bottom mud removal process, meeting the 7-day / layer progress of the caisson concrete structure construction, providing convenience for the caisson structure section operation without interfering with the structural construction;

[0020] 5. The top steel platform of this utility model can adopt light 321 type Bailey plate, which improves the overall safety of the device and provides a rare equipment integration site for high-altitude operations. The setting of hydraulic remote control concrete placing machine and small lifting equipment can effectively serve on-site construction and improve on-site work efficiency.

[0021] 6. The utility model places the horizontal mud pump pipe on the hanger, and the horizontal mud pump pipe rises together with the platform jacking, which reduces the installation and removal of the mud pump pipe and saves construction time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings.

[0032] like Figure 1 -8, the utility model shows an integrated platform for caisson construction equipment, comprising a supporting column 1, a rotatable screw rod 2, a steel platform 3, a lower hanger 4, a hanger 5, a one-way self-locking clamp 6, a shoulder pole 7, a hook 8, a climbing pole 9, a steel formwork 10, a hydraulic cylinder 11, a placing boom 13, a truss 16 and a winch 17.

[0033] like Figure 1 As shown, when the caisson construction equipment integrated platform is lifted, it is supported by three sets of brackets 5. The middle bracket serves as the primary load-bearing component for vertical forces, while the upper and lower brackets 5 primarily bear horizontal forces to prevent the columns from tilting. The brackets 5 are connected to the caisson concrete structure via revolving bolts 2. A hook 8 is assembled with the bracket 5 via a pin. The hook 8 supports the support column via a window baffle 14 provided by the support column 1 itself. A shoulder pole 7 is connected to the bracket 5 via a pin. A one-way self-locking clamp 6 is mounted on the shoulder pole to clamp the upper portion of the climbing rod 9 and restrict its upward movement. The lower portion of the climbing rod 9 is connected to a crossbeam 12 built into the cavity of the support column 1 via a pin. The lower portion of the crossbeam 12 is connected to the lower portion of a hydraulic cylinder 11 built into the cavity of the support column. The upper portion of the hydraulic cylinder 11 is connected to a stiffening plate 22 inside the support column 1. The upper end of the support column 1 is fixedly connected to a steel platform 3, which is suspended from a lower bracket 4 via a suspender rod 18. The steel template 10 is suspended at the bottom of the steel platform 3 by a chain 19 .

[0034] The working principle of this utility model is as follows:

[0035] The extension of the hydraulic cylinder 11 pushes the support column 1 upward, disengaging the hook 8. The crossbeam 12 then transmits the downward force it receives to the climbing rod 9, then to the shoulder pole 7 and the hanger 5, and finally to the concrete structure of the caisson. After the hydraulic cylinder 11 drives the support column 1 upward for one stroke, the hook 8 again supports the support column 1. The hydraulic cylinder 11 retracts, allowing the climbing rod 9 and crossbeam 12 to rise for one stroke. Finally, the one-way self-locking clamp 6 of the shoulder pole 7 locks the climbing rod 9 again. The above steps are repeated, and the hydraulic cylinder 11 is raised multiple times in small strokes, completing the lifting of the support column 1 through the predetermined total stroke. During this process, the sensor 15 installed in the support column 1 monitors and provides feedback on the stroke of the hydraulic cylinder 11 and the action of the hook 8 supporting the support column 1. The lifting of the support column 1 drives the entire steel platform 3 upward, which in turn drives the steel formwork 10, the placing boom 13, the lower hanger 4, the truss 16, and the winch 17 upward.

[0036] like Figure 1 and Figure 6As shown, the hydraulic cylinder 11 is equipped with a displacement sensor 15 and a matching power pump station 23. The displacement sensor 15 is used to judge and feedback the extension length of the hydraulic cylinder. The power pump station 23 is used to provide power for the extension of the hydraulic cylinder 11, thereby realizing automatic lifting of the hydraulic cylinder 11 under the control of the electronic control system.

[0037] The lifting and supporting system of the utility model drives the steel platform to rise, thereby realizing the lifting of the integrated platform of the caisson construction equipment. The utility model can be widely used in caisson construction and similar lifting or lifting and supporting structures of the lifting system, which also fall within the scope of protection of the utility model.

[0038] In the above embodiment, support column 1 includes high-strength bolts, steel sections, window baffles 14, horizontal stiffeners 22, steel plates, and connecting bolts. A single support column 1 has a load-bearing capacity of 50 tons. The window baffles 14 provide a support point for hook 8, and the internal cavity provides adequate protection for hydraulic cylinder 11 and sensor 15.

[0039] In the above embodiment, the steel platform 3 is constructed by combining standard 321-type Bailey panels (1.5m high and 3m long) with non-standard Bailey panels (not 3m long) spliced horizontally and vertically. The Bailey panel layout was specifically designed based on the caisson's planar structure and adopted after overall modeling and calculation using Midas calculation software. The top surface of the steel platform 3 is designed for pedestrians and material storage, and can accommodate a concrete placing boom 13. The lower portion can accommodate trusses 16 and winches 17. The underside of the steel platform 3 is equipped with a hanging system suspended by booms 18 to assist with construction on the working level.

[0040] In the above embodiment, a facade protection net 20 is provided on the facade of the steel platform 3. The facade protection net 20 is arranged on both sides of the Bailey plate on the top of the steel platform. Its purpose is to meet the necessary protective measures for on-site safety operations. The integrated design with the caisson construction equipment integrated platform further highlights the safety characteristics of the platform.

[0041] In the above embodiment, the lower pylon 4 is suspended from the bottom of the steel platform via a suspender 18. The pylon system includes the suspender 18, a small crossbar, a patterned steel walkway plate, a patterned steel flap, and other components. These components are assembled by welding bolts, pins, and flat iron. The walkway has seven or more steps, with a single step height of 2 meters or more. The top walkway of the lower pylon 4 serves as a construction platform for the caisson steel formwork 10 structure. The middle area of the lower pylon 4 serves as a channel for the air supply and exhaust pipes. The middle walkway of the lower pylon 4 serves as a cleaning and maintenance platform for the structural facade after formwork removal. The bottom walkway of the lower pylon 4 serves as a construction platform for the revolving screws used to remove the pylons.

[0042] In the above embodiment, a one-way self-locking clamp 6 is installed on the shoulder pole 7, which can clamp the upper part of the climbing pole 9, which is sufficient to offset the vertical downward pulling force of the supporting column 1 during the rising process, thereby limiting the climbing pole 9 to only be able to move upward, and also has the function of a fall arrester.

[0043] In the above embodiment, the hook 8 is made of steel plate. When the support column 1 rises, the hook 8 can rotate by the upward friction force of the support column 1, thereby not hindering the rise of the support column 1. However, when the support column 1 descends and encounters the window pane baffle 14, the hook 8 will automatically rotate under its own gravity and support the window pane baffle 14 of the support column 1.

[0044] In the above embodiment, the climbing pole 9 is made of solid 45# round steel, which can support the vertical force exerted on the entire supporting column 1 and is more conducive to controlling the verticality of the supporting column 1 during the rising process, and rises with the recovery of the hydraulic cylinder 11.

[0045] In the above embodiment, the hydraulic cylinder 11 is a cavity built into the interior of the support column 1. A speed-controlled motor drives a bidirectional hydraulic pump, which directly drives the hydraulic cylinder to extend, thereby pushing the support column 1 upward. Multiple hydraulic cylinders 11 are dynamically adjusted and monitored synchronously through oil pressure and real-time displacement, achieving synchronous extension of multiple hydraulic cylinders 11 and, consequently, synchronous elevation of multiple support columns 1.

[0046] In the above embodiment, the sensor 15 is installed in the cavity inside the support column 1, closely integrated with each hook window baffle 14 of the support column 1, and uses a photoelectric sensor. The sensor 15 can monitor the movement of the hook and provide feedback on the load-bearing status, thereby enabling monitoring and feedback of the jacking process.

[0047] In the above embodiment, the formwork system includes a chain 19, a connector 21, and a steel formwork 10. The steel formwork 10 is connected to the steel platform 3 via the connector 21. The steel formwork 10 is installed and removed as a whole during use. After the steel formwork 10 is demolded by the tensioning screws, it is moved backward as a whole to disengage from the vertical structure of the caisson. After the caisson construction equipment integrated platform is self-lifted for a section, it is moved forward to close the mold, thus realizing the integrated design of the formwork system and the caisson construction equipment integrated platform.

[0048] In the above embodiment, the concrete placing boom 13 is placed atop the steel platform 3. In this embodiment, the concrete placing boom 13 is a remote-controlled boom, comprising a fixed base, a hydraulic rotary table, and an adjustable placing arm. These units are typically supplied as complete sets by specialized manufacturers. The base of the concrete placing boom 13 is fixed to the top surface of the steel platform 3. Simply connecting the pump pipe to the bottom of the concrete placing boom 13 allows for concrete pouring and distribution over a wide area within the caisson, improving both the convenience and efficiency of concrete pouring.

[0049] In the above embodiment, the truss 16 and the winch 17 are arranged at the bottom of the steel platform 3. The winch 17 can move horizontally on the truss 16, and can lift and transport the mud pump within the caisson range. At the same time, it can also facilitate the lifting and material transportation of small weight operations in the working area, thereby improving the level of on-site assembly operations.

[0050] In the above embodiment, compared with the traditional mold turning device, the lower hanging bracket 4 of the utility model can cover a higher height, the bottom surface of the steel platform 3 is integrated with the hanging steel formwork 10, and the top surface of the steel platform 3 is integrated with the fabricating machine. The longitudinal and transverse structures of the steel platform 3 tie the outer ring frame together to enhance the overall safety of the device, which has obvious advantages over the traditional mold turning device.

[0051] In the above embodiment, the suspended steel formwork 10 is first disconnected from the caisson concrete structure before the device is lifted, and then the steel formwork 10 is carried up to the height of a construction section by the power of the hydraulic cylinder 11, and the vertical reinforcement of the previous section is tied. After the vertical reinforcement of the previous section is tied, the steel formwork 10 is closed, and finally the concrete placing machine 13 is used to pour the concrete, completing a standard process of construction. The construction period of a standard layer is 15 days.

[0052] The implementation process is shown in the attached Figure 8a - Figure 8. This utility model provides a "steel cover"-like protection around and on the top of the working surface by setting a low-position wall-mounted support point at the bottom of the working layer. At the same time, construction auxiliary equipment and frames are integrated with it to achieve maximum auxiliary effect on on-site services. The standard construction process is 15 days / layer. See the flow chart for details. The following only describes the key working procedures of the building equipment operation.

[0053] In the first step, the concrete pouring of the vertical structure of the n-layer caisson is completed to the initial state.

[0054] Step 2: After the n-layer caisson vertical structure steel formwork 10 meets the dismantling conditions, the reinforcing screw rods and back ribs are removed to separate the n-layer caisson vertical structure steel formwork 10 from the structure.

[0055] Step 3: Flip up the horizontal protective flap of the hanger system, check whether the lower hanger 4 and the steel formwork 10 are detached from the structure, and then control the hydraulic device through the control room on the top surface of the steel platform 3 to lift the support column 1 together with the entire caisson construction equipment integrated platform by one structural section.

[0056] Step 4: Tie up the n+1 layers of vertical reinforcements, and inspect the vertical reinforcements after tying is completed.

[0057] Step 5: Support the caisson steel formwork 10 and close the mold for the n+1 layer of vertical steel bars. The area where the formwork 10 is hung only needs to push the formwork 10 toward the wall and clamp it to the wall.

[0058] Step 6: Pour the n+1 layer of vertical concrete.

[0059] Step 7: Return to the first step, enter the initial state, and repeat the construction operation repeatedly.

[0060] During the structural construction process, the crane system under the steel platform mobilizes the mud pump to discharge the mud in the caisson.

[0061] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the present invention and the claims, which are all within the protection of the present invention.
