[0040] Embodiment 1:

[0041] like Figures 1 to 6 As shown, a metal-knot gate installation auxiliary construction device includes a tower device 1, a steel strand tensioning and lifting device 2, a tower installation jacking device 3, a top temporary protection device 4, a mobile temporary protection device 5, a pier device 6 and a control system, etc. The control system includes a master control device and a sub-control device. The master control device is a master controller and supporting software arranged on site or remotely. The master control device controls the sub-control devices arranged on the tower device 1, the steel strand tensioning and lifting device 2, the tower installation jacking device 3, the top temporary protection device 4, the mobile temporary protection device 5, etc. respectively to ensure their reliable operation.

[0042] The tower device 1 is arranged at the top of the gate slot 8. The tower device 1 includes a plurality of towers. The towers are arranged on the platform 9 at the top of the gate slot 8. Each tower is provided with a plurality of tower sections 101 according to the needs of the gate lifting height. A plurality of cross beams 102 are set on the top of the tower. A plurality of longitudinal beams 103 are arranged on the upper side of the cross beams 102. The steel strand tensioning and lifting device 2 is installed on the longitudinal beams 103.

[0043] After the construction of the gate slot 8 is completed, a top temporary protection device 4 is provided on the top of the gate slot 8. The top temporary protection device 4 is used to protect the opening during the installation of the tower, superstructure and equipment to prevent objects from falling into the gate slot and causing damage to the gate or the gate slot.

[0044] like Figure 8 and 9 As shown, the top temporary protection device 4 includes a top cover plate 401 , which covers the top of the slot of the door slot 8 , and a lifting ear 402 is provided on the outer side of the top cover plate 401 .

[0045] Preferably, the top cover plates 401 are arranged in multiple groups, and adjacent top cover plates 401 are hinged by hinged brackets 404. An electric push rod 403 is provided on one of the two adjacent groups of top cover plates 401. The electric push rod 403 is hingedly mounted on the corresponding top cover plate 401, and the telescopic end of the electric push rod 403 is hinged to the adjacent top cover plate 401. During specific use, the electric push rod 403 is powered by a battery, and the telescopic movement of the electric push rod 403 is controlled by an accompanying controller.

[0046] In this embodiment, three groups of top cover plates 401 are provided, and the top cover plates 401 at both ends can be rotated relative to the middle top cover plate 401, so that the top temporary protection device 4 can be folded or laid flat.

[0047] If the top temporary protection device 4 needs to be flattened or folded, the electric push rod 403 is controlled to extend and retract through the accompanying controller, further driving the top cover plate 401 to be folded or laid flat. When multiple groups of top cover plates 401 are flipped and folded, it is convenient for transportation and hoisting and transfer. Laying flat can fully cover the door slot opening, thus achieving a good protection effect.

[0048] Preferably, Figure 6 As shown, a clamping tube 104 is provided on the platform 9 at the bottom of the tower, and a bolt base 105 is provided on the outer side of the clamping tube 104. The clamping tube 104 is fixedly connected to the bolt base 105. The tower section 101 at the lower end of the tower is sleeved on the clamping tube 104 and connected to the bolt base 105 by bolts. The clamping tube 104 is used to position the tower section 101 during the installation process.

[0049] A tower installation jacking device 3 is provided on the platform 9 at the bottom of the tower for installing the tower. The tower installation jacking device 3 includes a jacking cylinder 301. The telescopic end of the jacking cylinder 301 is provided with a connecting rod 302. The connecting rod 302 is arranged horizontally. A jacking plate 106 is provided on one side of the tower section 101. The jacking plate 106 is connected to the connecting rod 302 by bolts.

[0050] Preferably, Figure 7 As shown, a support 303 is provided at the bottom of the jacking cylinder 301 , and the support 303 is connected to the platform 9 at the bottom of the tower through bolts, and a reinforcing rib is provided between the support 303 and the jacking cylinder 301 .

[0051] When in use, the lifting cylinder 301 is connected to the lifting plate 106 of the first tower section 101 through the connecting rod 302, and the lifting cylinders 301 corresponding to the multiple towers are extended synchronously to lift the first tower section 101 upward. After lifting a tower section 101 to a certain height, the second tower section 101 is inserted under the first tower section 101, and then installed in alignment with the clamping pipe 104. The lifting cylinder 301 is retracted, and the first tower section 101 and the steel strand are tensioned and lifted. The device 2 falls back synchronously, and the first tower section 101 falls to the upper side of the second tower section 101. The first tower section 101 and the second tower section 101 are connected by bolts, and then the bolt connection between the connecting rod 302 and the jacking plate 106 on the side of the first tower section 101 is released, the jacking cylinder 301 is reset, and then the jacking cylinder 301 is connected to the jacking plate 106 of the second tower section 101, and the above-mentioned jacking operation is repeated until the tower is erected to a predetermined height.

[0052] The steel strand tensioning and lifting device 2 includes a winding drum 201. One end of the steel strand 202 is fixed and wound on the winding drum 201. The other end is guided by a winding frame 203 and connected to a lifting device 205 through a lifting mechanism 204. The winding frame 203 is connected to the longitudinal beam 103 through a support frame. The lifting mechanism 204 is used to lift the steel strand 202 up and down.

[0053] The steel strand 202 is fixedly wound and stored at one end in the winding drum 201 and then extended. It is guided by the winding frame 203 and driven by the lifting mechanism 204 to be retracted. The other end of the steel strand 202 is fixedly connected to the lifting ear of the gate 7 through the lifting device 205 through a pin shaft to lift the gate 7 up and down.

[0054] It also includes a control cabinet for overall control of the raising and lowering of the steel strand tensioning lifting device.

[0055] The lifting mechanism 204 is a system that uses flexible steel strands to bear the load, lifting cylinder clusters, computer control, and hydraulic synchronous lifting, and is the core mechanism of the entire system. Figure 4 As shown, it includes a lifting main cylinder 2041, which uses a through-cylinder. The lifting main cylinder 2041 is connected to the lower clamping cylinder 2043 through a lower support column 2042. The telescopic component of the lifting main cylinder 2041 is connected to the upper clamping cylinder 2044. The steel strand 202 is passed through the lifting main cylinder 2041 and fixed by the upper clamping cylinder 2044 or the lower clamping cylinder 2043.

[0056] The upper clamp oil cylinder 2044 and the lower clamp oil cylinder 2043 rely on the self-locking of the conical anchor plate and the anchor seat to make the teeth of the inner ring gripping surface of the conical anchor plate engage with the steel strand and transmit friction force.

[0057] When the gate is opened, the upper clamp cylinder 2044 uses the mechanical self-locking of the anchor plate to tightly clamp the steel strand, lift the main cylinder 2041 to extend the cylinder, tension the steel strand once, and lift the gate by one stroke; lift the main cylinder 2041 to full stroke and retract the cylinder, so that the load is transferred to the lower clamp cylinder 2043, and the upper clamp cylinder 2044 is released, and the gate rises step by step. When the gate is closed, there will be a self-locking release process of the upper or lower anchor, and the gate will descend step by step.

[0058] Embodiment 2:

[0059] Different from Example 1, Figures 8 to 11 As shown, it also includes a mobile temporary protection device 5 and a pier device 6.

[0060] When the gate 7 is installed in the gate groove 8, the gate groove 8 above the gate 7 is still under construction. In order to prevent the steel bars, concrete, cement slurry, etc. during the construction process from damaging the gate 7, the gate groove 8 or the water seal, a movable temporary protection device 5 is set on the top of the gate 7.

[0061] like Figure 8 and Fig.10 As shown, the mobile temporary protection device 5 includes an airbag type cap cushion 501 arranged on the top of the gate 7. The airbag type cap cushion is an elastic airbag with an inflation and exhaust nozzle. The air nozzle 502 of the airbag type cap cushion 501 is connected to the air pump 503 through a pipeline. The power supply machine 504 provides power to the air pump 503. The airbag type cap cushion 501 is provided with a control box 505 for controlling the power supply machine 504. The control box 505 is provided with original components such as an air pump and a battery. The power supply machine 504 is preferably a fan of a vertical axis type, which generates electricity through the through wind in the gate slot flow channel and stores it in the battery 507.

[0062] Preferably, the side of the corner of the airbag cap cushion 501 is provided with a multi-layer stop grout ring 506. The airbag cap cushion 501 expands after being inflated, and the stop grout rings 506 at the four corners are close to the inner wall of the gate slot, so that the debris or concrete slurry dropped during the construction of the upper gate slot will be intercepted by the stop grout ring and will not enter the lower gate slot, avoiding affecting the subsequent installation and lifting of the gate, and also avoiding the debris stuck between the gate slot and the gate, causing damage to the gate or the gate slot when the gate is lifted.

[0063] In order to ensure the passage of subsequent construction in the gate and the flow channel behind the gate slot after the gate is installed, a pier device 6 is provided on the bottom sill 10 to elevate the gate.

[0064] like Fig.11 As shown, the pier device 6 includes a bottom pier 601 and multiple groups of stacked piers 602 arranged on the upper side of the bottom pier 601. The bottom pier 601 and the piers 602 arranged on the bottom pier 601 are preferably made of metal to ensure that they can withstand the overall weight of the gate.

[0065] A resistance-enhancing pad 603 is provided at the bottom of the bottom pier 601 so that the bottom pier can be pressed on the bottom sill of the door groove without damaging the bottom sill.

[0066] Preferably, the tops of the bottom pier 601 and the mark pier 602 are both provided with a clamping strip 604, and the bottom of the mark pier 602 is provided with a clamping groove 605, which cooperates with the adjacent clamping strip 604, and the clamping strip 604 is an arc-shaped long protrusion, and the clamping groove 605 is an arc-shaped groove.

[0067] Through the cooperation between the clamping strip 604 and the clamping groove 605, the pier device 6 will not be dislocated or overturned when the top is subjected to the gate pressure load.

[0068] The operation process of the auxiliary construction device for installing the metal-knot gate in the utility model is as follows:

[0069] Step 1: Construction of the lower section of the gate slot: First install the gate slot sill and the lower section of the gate slot, and pour concrete to prepare for gate assembly. The height of the installed lower section of the gate slot is higher than the gate height plus the height of the pier device 6. This ensures that the equipment channel is unobstructed while completing the gate assembly.

[0070] Step 2: Low-position assembly of the gate: Install the bottom pier 601 and multiple standard piers 602 on the bottom sill of the gate. The resistance-increasing pad 603 at the bottom of the bottom pier 601 increases the friction between the support pier device and the bottom sill and the bottom plate.

[0071] Small hoisting equipment is used above the pier to assemble, measure and adjust the gate section by section. Because the gate is installed in the lower door slot at a lower elevation from the bottom plate, it can be quickly installed with only small hoisting equipment, which can effectively speed up the installation progress and save installation time.

[0072] Step three, move the temporary protection device 5 to install protection: install the airbag cap pad 501 on the top of the assembled gate 7 to effectively protect the gate 7. Powered by the battery, through the control box 505 of the master control device, start the air pump 503 to inflate the airbag cap pad 501. The inflated airbag cap pad 501 forms a certain thickness, which can form a good protection effect on the top of the gate. At the same time, the inflated airbag cap pad 501 expands, and the stop rings 506 at the four corners are close to the inner wall of the gate groove. In this way, the debris or concrete slurry dropped during the construction of the upper gate groove will be intercepted by the stop ring and will not enter the lower gate groove, so as to avoid affecting the subsequent installation and lifting of the gate.

[0073] During specific use, an air pressure sensor is also provided on the air nozzle 502. The air pressure sensor automatically measures the air pressure of the airbag cap cushion 501 throughout the whole process. For example, when the air pressure in the airbag cap cushion 501 is insufficient due to leakage pressure, the main control device controls the control box to start the air pump 503 to inflate and pressurize the airbag cap cushion 501 according to the air pressure signal automatically transmitted back to the main control device, until the air pressure in the airbag cap cushion 501 returns to a predetermined range.

[0074] Step 4: Construction of the upper section of the gate slot: After the airbag cap pad 501 effectively protects the gate 7, the installation of the upper section of the gate slot can be continued. First, the gate slot is installed, and then the gate slot concrete is poured after measurement until the gate slot is installed and poured to the top.

[0075] Step 5, install the top temporary protection device 4: After the door slot 8 is installed to the top, the top cover plate 401 can be installed. First, use a small lifting device on the platform 9 at the top of the door slot to properly position the folded top cover plate 401 on the top of the door slot 8 by lifting the ears 402 on both sides of the top cover plate 401, and then start the electric push rod 403 to flip the folded top cover plate 401 piece by piece and gradually unfold it to form a flat cover on the top of the door slot 8. The top temporary protection device 4 is opened to a flat state to achieve good protection for the door slot and the gate. The unfolded top cover plate can also form a flat platform to provide a good site for the installation of the lifting device.

[0076] Step 6, installation of the strand tensioning and lifting device 2 and subsequent installation of the gate: first measure and position on the top platform 9 of the gate groove 8, install the clamping pipe 104 and the bolt base 105 by pre-embedding and then pouring the second phase concrete and then installing, install the tower jacking device 3 corresponding to the tower installation position, then install the first tower section 101, install the cross beam 102 and the longitudinal beam 103 on the first tower section 101, and then install the strand tensioning and lifting device 2, install the winding drum 201, the winding frame 203 and the lifting mechanism 204, the support frame and the control cabinet on the longitudinal beam 103, fix one end of the steel strand 202 on the winding drum 201 and then connect the other end to the lifting device 205, ensure that the connecting rod 302 of the jacking cylinder 301 and the bolt holes of the jacking plate 106 on the side of the tower section 101 can be well aligned, and then reliably install it by threading the bolts.

[0077] During the installation of the steel strand tensioning and lifting device 2, because of the isolation and protection of the temporary protective device 4 on the top, the installation of the pre-installed gate in the gate slot can continue. In order to save the installation period, the gate is started to be measured, aligned and spot welded between sections. At this stage, the welding of the inter-section welds that are not disturbed by the gate slot and the installation of related accessories are carried out.

[0078] Step 7, tower lifting: the lifting cylinder 301 is connected to the lifting plate 106 of the first tower section 101 through the connecting rod 302, and the lifting cylinders 301 corresponding to the multiple towers are synchronously extended to lift the first tower section 101 upward. After lifting a tower section 101 to a certain height, the second tower section 101 is inserted under the first tower section 101 by a forklift or other means, and then installed in alignment with the clamping pipe 104. The lifting cylinder 301 retracts, and the first tower section 101 and the steel strand are lifted. The wire tensioning lifting device 2 falls back synchronously, and the first tower section 101 falls to the upper side of the second tower section 101. The first tower section 101 and the second tower section 101 are connected by bolts, and then the bolt connection between the connecting rod 302 and the jacking plate 106 on the side of the first tower section 101 is released, the jacking cylinder 301 is reset, and then the jacking cylinder 301 is connected to the jacking plate 106 of the second tower section 101, and the above jacking operation is repeated until the tower is erected to a predetermined height.

[0079] Step 8: Subsequent installation of the gate: Lift the temporary top protection device 4 away from the gate slot 8, start the electric push rod 403 to fold the top cover plates 401, and then lift the temporary top protection device 4 away. After controlling the airbag cap pad 501 to release pressure, use the small lifting equipment or the steel strand tensioning lifting device 2 to adjust it away from the gate slot, start the steel strand tensioning lifting device 2 again, lower the lifting device 205, connect the lifting device 205 with the lifting ear of the gate 8 through the through pin shaft, lift the gate 8 through the steel strand tensioning lifting device 2, and then adjust the length of each steel strand 202, adjust the top of the gate 8 to the horizontal level, and then lift the steel strand 202 as a whole, gradually lift the gate 8 out of the gate slot 7, weld the welds of the gate 8 at the part interfered by the gate slot 7 and install the accessories, and then use the small lifting equipment or the steel strand tensioning lifting device to evacuate the pier device 6.

[0080] In this way, the gate is installed through three stages and finally completed. In this way, the installation and commissioning of all gates and lifting devices are completed. With this installation method, on the one hand, the gate is installed in the lower gate slot at a low elevation, which is easy to install and can be completed with small installation equipment. On the other hand, most of the gate installation time coincides with the installation time of the upper gate slot and lifting device, which is very beneficial to the tight overall construction period, and the economic and progress benefits are very significant.

[0081] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention.
