Abstract

The invention relates to a large-dip-angle bare rock pier construction operation platform based on a deepwater area, and belongs to the technical field of engineering construction. By arranging the stop assembly, after the lifting platform moves to the corresponding height of the pier, the telescopic unit enables the abutting block to be attached to the side wall face of the pier by extending the output end, the lifting platform is fixed to a certain height of the pier, and even if the lifting platform located on the seabed is impacted by seabed undercurrent at the moment, the abutting block can abut against the side wall face of the pier. And the lifting platform does not shake violently, and construction treatment of constructors located on the lifting platform on the pier is not affected. It is worthy of being explained that after the abutting block relieves the attaching arrangement relation between the abutting block and the side wall face of the bridge pier, the lifting table can ascend and descend again along the bridge pier; in addition, due to the arrangement of the moving assembly, the friction resistance between the lifting table and the bridge pier is reduced when the lifting table slides.

DETAILED DESCRIPTION

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] See also Figure 1-Figure 5The present embodiment provides a construction work platform for high-angle bare rock piers in deep water areas, comprising a hollow lifting platform 1, a plurality of moving components 2 and a plurality of stop components 3. The lifting platform 1 can be lifted and lowered on the pier on the seabed. The plurality of moving components 2 are matched one-to-one with the side wall surfaces of the piers. The moving component 2 comprises a roller 201 and a connecting shaft 202. One end of the connecting shaft 202 is connected to the roller 201, and the other end of the connecting shaft 202 is connected to the inner wall of the lifting platform 1. The roller 201 is slidably connected to the corresponding side wall surface of the pier. The plurality of stop components 3 are matched one-to-one with the side wall surfaces of the piers. The stop components 3 comprise a telescopic unit and an abutment block 301. The two ends of the telescopic unit are respectively connected to the lifting platform 1 and the abutment block 301. The abutment block 301 can lock or release its fitting setting relationship with the side wall surface corresponding to the pier. By setting There is a stop assembly 3. When the lifting platform 1 moves to the corresponding height of the pier, the telescopic unit extends the output end so that the abutment block 301 and the side wall of the pier are fitted together, so that the lifting platform 1 is fixed at a certain height of the pier. Even if the lifting platform 1 on the seabed is impacted by the submarine undercurrent at this time, the lifting platform 1 will not shake violently, and will not affect the construction workers on the lifting platform 1 to carry out construction work on the pier, which solves the problem that for piers installed in deep water areas, it is generally necessary to install an operating platform to assist workers in installing the piers; however, due to the presence of submarine undercurrents in deep water areas, after the operating platform is installed on the pier, the submarine undercurrent will impact the operating platform, causing the operating platform to shake, thereby affecting the construction speed and efficiency of the workers standing on the operating platform, thereby reducing the construction progress of the entire pier. It is worth noting that when the abutment block 301 releases its fitting relationship with the side wall of the pier, the lifting platform 1 can be lifted and moved along the pier again; in addition, the setting of the moving component 2 is to reduce the friction resistance between the lifting platform 1 and the pier when it slides.

[0031] In addition, in order to realize the lifting and lowering of the lifting platform 1, the present solution also includes a rope 4. The crane is arranged on the shore. The two ends of the rope 4 are respectively connected to the output end of the crane and the lifting platform 1 to control the height of the lifting platform 1.

[0032] Furthermore, the telescopic unit of the present scheme includes an internally hollow fixed rod 302, a sliding rod 303 and a telescopic spring 304, one end of the fixed rod 302 is connected to the side wall of the lifting platform 1, the sliding rod 303 is slidably set at the other end of the fixed rod 302, the telescopic spring 304 is set in the fixed rod 302, the two ends of the telescopic spring 304 are respectively connected to the fixed rod 302 and the sliding rod 303, and the end of the sliding rod 303 away from the fixed rod 302 is connected to the abutment block 301; it is worth mentioning that when the sliding rod 303 extends out of the fixed rod 302, the abutment block 301 realizes its fitting setting with the side wall of the pier; when the sliding rod 303 is reset due to the action of the telescopic spring 304, the abutment block 301 releases its relationship of fitting setting with the side wall of the pier.

[0033] According to the above embodiment, the telescopic spring 304 functions to drive the sliding rod 303 to retract into the fixed rod 302 for resetting, so an external force is required to drive the sliding rod 303 to extend out of the fixed rod 302; in order to solve this problem, the stop assembly 3 of the present scheme also includes a sealing block 305, and the lifting platform 1 is provided with a plurality of driving grooves and a plurality of connecting grooves, and the plurality of driving grooves are not connected to each other, and the plurality of driving grooves are matched one-to-one with the plurality of telescopic units, and the interior of any fixed rod 302 is connected to the corresponding driving groove; the plurality of connecting grooves are matched one-to-one with the plurality of driving grooves, and any connecting groove The groove is arranged in the corresponding driving groove, and the connecting groove is connected with the external environment and the corresponding driving groove respectively; any sealing block 305 is slidably arranged in the corresponding driving groove; the fixed rod 302 can lock or release the interconnection relationship between it and the corresponding connecting groove; the sealing block 305 is driven to move, and when the sealing block 305 moves to a certain distance away from the corresponding connecting groove, the inside of the fixed rod 302 is interconnected with the seawater, and the sliding rod 303 will be extended due to the water pressure until the abutment block 301 is arranged in contact with the side wall of the pier. Similarly, when the sealing block 305 moves in the direction close to the corresponding connecting groove, while discharging the seawater in the driving groove, the structural effect that the inside of the fixed rod 302 is no longer interconnected with the seawater can be achieved, and the sliding rod 303 is reset due to the force of the telescopic spring 304.

[0034] It should be noted that when the interior of the fixed rod 302 is interconnected with the seawater, if the sliding rod 303 needs to be extended due to the water pressure, a condition is also required, that is, the force exerted by the seawater pressure on the sliding rod 303 is greater than the force exerted by the seawater pressure on the abutment block 301; based on this, in order to solve this problem, the present scheme also includes two sets of closing components and drainage devices 9, the two sets of closing components are respectively arranged at the top and bottom of the lifting platform 1; the closing components include a plurality of closing units 8, and the plurality of closing units 8 are matched one by one with the side wall surfaces of the enclosed piers; the closing units 8 include a closing cylinder 801 and a closing block 802, the closing cylinder 801 is arranged on the lifting platform 1, and the closing block 802 is connected to the output end of the closing cylinder 801, and the closing block 802 is slidably and sealedly arranged on the surface of the lifting platform 1. The closing block 802 is driven to move by the closing cylinder 801, so that the closing block 802 and the side wall of the pier can be fitted together. When each closing block 802 is fitted together with the side wall of the pier, each closing block 802 and the lifting platform 1 can form a closed space together. The drainage device 9 is arranged in the closed space, and the drainage device 9 located in the closed space starts to discharge the seawater in the closed space, thereby achieving that the force of the seawater water pressure in the closed space on the abutment block 301 is smaller than the force of the seawater water pressure outside the closed space on the sliding rod 303.

[0035] In order to enable several sealing blocks 305 to move simultaneously and to enable each sliding rod 303 to extend or retract synchronously; the stop assembly 3 of this scheme also includes several driving blocks 306, and the lifting platform 1 is provided with several sliding grooves, and the several sliding grooves are matched one by one with the several driving grooves. Any sliding groove is set at the top of the corresponding driving groove, and the setting direction of the sliding groove is the same as the setting direction of the corresponding driving groove. The several sliding grooves are connected to each other, and any driving block 306 can be slidably sealed in the corresponding sliding groove. The driving block 306 is connected to the corresponding sealing block 305, and the sliding groove space between two adjacent driving blocks 306 forms a hydraulic space, and the hydraulic oil is filled in the hydraulic space; by providing the sliding groove, since the adjacent sliding grooves are connected to each other, and the driving block 306 is set in the corresponding sliding groove, the sliding groove space between two adjacent driving blocks 306 forms a hydraulic space, and the hydraulic oil is filled in the hydraulic space. When one driving block 306 moves, the remaining driving blocks 306 will also move synchronously due to the action of the hydraulic oil. In addition, since each driving block 306 is connected to the corresponding sealing block 305 , each sealing block 305 can move simultaneously in the corresponding driving groove, and each sliding rod 303 can be extended or retracted synchronously.

[0036] According to the above embodiments, the present solution ensures that the driving block 306 and the sealing block 305 are connected to each other and slide synchronously, and also needs to ensure that the hydraulic oil in the hydraulic space does not leak; based on this, the stop assembly 3 of the present solution also includes a plurality of sealing belts 307, and the lifting platform 1 is provided with a plurality of annular sealing grooves, and the plurality of annular sealing grooves are matched one by one with the plurality of sliding grooves, and any annular sealing groove is arranged at the connection between the corresponding sliding groove and the driving groove, and one end of the annular sealing groove is connected to the connection between the sliding groove and the driving groove, and any sealing belt 307 is slidably sealed in the corresponding annular sealing groove, and the sealing belt 307 is also provided with a sealing hole, and the sealing hole is sealed with the driving block 306; by providing the sealing belt 307, the function of the sealing belt 307 is to seal the connection between the driving groove and the sliding groove, and the sealing hole provided with the sealing belt 307 enables the driving block 306 to pass through the sealing hole and be connected with the sealing block 305, and because the driving block 306 and the sealing hole are sealed with each other, the sealing of the hydraulic space is further achieved.

[0037] It is also worth mentioning that in order to further improve the stability of the lifting platform 1, the present solution also includes a support unit 5, which includes a plurality of telescopic rods 501 with hollow interiors and a support cylinder 502. The support cylinder 502 is arranged on the outer wall of the lifting platform 1, and the telescopic direction of the output end of the support cylinder 502 is consistent with the setting direction of the driving groove close to it. The outer diameters of the plurality of telescopic rods 501 are different. The plurality of telescopic rods 501 are coaxially slidably arranged in adjacent telescopic rods 501 in sequence by mutual sleeve arrangement. The telescopic rod 501 with the largest outer diameter is connected to the outer wall of the lifting platform 1, and the output end of the support cylinder 502 is connected to the telescopic rod 501 with the smallest outer diameter. The telescopic rod 501 with the smallest outer diameter can lock or release its fitting relationship with the bare rock; by providing the support cylinder 502, when the output end of the support cylinder 502 is extended, the support cylinder 502 will control the telescopic rod 501 with the smallest outer diameter to extend, thereby realizing its counter-fitting relationship with the bare rock, thereby further increasing the stability of the lifting platform 1.

[0038] In addition, it is worth mentioning that the present solution also includes a linkage rod 6. A linkage slot is provided on the side wall of the lifting platform 1 close to the supporting cylinder 502. The linkage slot is interconnected with the sliding slot. One end of the linkage rod 6 is connected to the output end of the supporting cylinder 502, and the other end thereof is connected to the driving block 306 through the linkage slot. The distance between the telescopic rod 501 with the smallest outer diameter and the bare rock is greater than the distance between the connecting point between the fixed rod 302 and the driving slot and the connecting slot. By such a setting, it can be ensured that when the output end of the supporting cylinder 502 begins to extend, the stop assembly 3 has started to work, so that the abutment block 301 and the side wall of the pier are abutted against each other, thereby achieving the stopping effect of the lifting platform 1, and facilitating the subsequent setting of the telescopic rod 501 with the smallest outer diameter and the bare rock. In addition, when the telescopic rod 501 with the smallest outer diameter is contracted, since the stop assembly 3 is still working, it is avoided that the height of the lifting platform 1 changes during the contraction of the telescopic rod 501, thereby causing the telescopic rod 501 to collide with seabed debris, thereby causing the structure of the telescopic rod 501 to deform.

[0039] It is also worth mentioning that in order to further ensure the sealing of the lifting platform 1, the present solution also includes a waterstop 7. The lifting platform 1 is also provided with an annular linkage groove, one end of which is interconnected with the linkage groove hole, and the waterstop 7 is slidably and sealedly arranged in the annular linkage groove. The waterstop 7 is provided with a waterstop groove hole, and the linkage rod 6 is sealed and connected with the waterstop groove hole; by providing the waterstop 7, the function of the waterstop 7 is to seal the annular linkage groove. Since one end of the annular linkage groove is overlapped and connected with the linkage groove hole, the sealing cooperation of the waterstop 7 to the linkage groove hole is achieved; in addition, the waterstop 7 is also provided with a waterstop groove hole. The purpose of the waterstop groove hole is to seal and cooperate with the linkage rod 6, thereby achieving the connection between the linkage rod 6 and the driving block 306, and at the same time, the sealing of the lifting platform 1 can be ensured.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
