Description

Technical Field

[0001] The invention relates to the technical field of bridge structure construction, in particular to a self-floating steel truss drilling platform structure. Background Art

[0002] The steel truss drilling platform for bridges is a platform specially designed for drilling operations in bridge foundation construction. It is usually composed of a platform truss structure, a platform panel structure, upper and lower guide ring structures, a portal pile guide structure, a hanging structure, etc. Among them, the platform truss structure is the main load-bearing component of the drilling platform, which is composed of upper and lower chords, web members and truss braces. These components are connected into a whole through node plates to form a stable load-bearing structure.

[0003] Steel trusses used in bridges are generally heavy and need to be moved by cranes. Large-tonnage ships are needed to transport them in the water and then install them, which results in a lot of time being wasted in assembling the steel trusses. Various equipment is needed to assist in moving the entire trusses in the water, resulting in high installation costs. Improvements need to be made to this problem. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a self-floating steel truss drilling platform structure, including a steel truss drilling platform, and also including a driving assembly, an adjustment assembly and a self-floating assembly, and the four corners of the bottom of the steel truss drilling platform are fixedly connected with a positioning box.

[0006] Wherein, the driving component comprises: A fixed plate is fixedly connected to the outside of the positioning box, a hydraulic lifting rod is fixedly connected to the top of the fixed plate, the hydraulic lifting rod has a telescopic end, the telescopic end of the hydraulic lifting rod is fixedly connected to the lifting plate, and a lifting frame is fixedly connected to the outside of the lifting plate.

[0007] According to the above technical solution, the adjustment assembly includes a rotating block, an extension plate, a fixed arm, a support block and an extrusion wheel. The rotating block is rotatably connected to the middle part of the lifting frame, the extension plate is fixedly connected to the side of the rotating block away from the lifting frame, the fixed arm is fixedly connected to the bottom of the outer side of the positioning box, the support block is fixedly connected to the top of the fixed arm, and the extrusion wheel is rotatably connected to the outer side of the support block.

[0008] According to the above technical solution, the self-floating component includes a storage tank, an airbag, an extension pipe rack, a diversion pipe, a connecting hose and a floating water bag. The storage tank is opened inside the positioning box, the airbag is fixedly connected to the bottom of the storage tank, the extension pipe rack is fixedly connected to the top of the airbag, the diversion pipe is fixedly connected to the side of the extension pipe rack away from the airbag, the connecting hose is fixedly connected to the outside of the diversion pipe, and the floating water bag is fixedly connected to the end of the connecting hose away from the diversion pipe.

[0009] According to the above technical solution, the telescopic end of the hydraulic lifting rod passes through the top of the fixed plate and extends to the lower side of the fixed plate and is fixedly connected to the top of the lifting plate. A sliding groove is provided in the lifting plate, and the lifting plate is slidably connected to the outer wall of the positioning box through the sliding groove, so that the lifting plate can be lifted and lowered on the outer wall of the positioning box.

[0010] According to the above technical solution, the top of the extrusion wheel is in sliding contact with the bottom of the extension plate, so that when the extension plate extrudes the top of the extrusion wheel, the extrusion wheel slides on the bottom of the extension plate, and the bottom of the extension plate can be supported at the same time. The top of the lifting frame is fixedly connected to a limiting plate, and the limiting plate is used to limit the rotating block when the rotating block rotates.

[0011] According to the above technical solution, a solenoid valve is arranged on the back of the airbag, and by arranging the solenoid valve, the air and water flow in and out of the airbag can be controlled.

[0012] According to the above technical solution, the bottom of the extension pipe rack passes through the top of the lifting plate and extends to the lower side of the lifting plate and is fixedly connected to the top of the airbag, and the extension pipe rack is communicated with the inside of the airbag, and the bottom of the floating water bag is fixedly connected to the side of the extension plate away from the positioning box, so that when air enters the floating water bag, it can provide upward buoyancy to the extension plate in the water.

[0013] According to the above technical solution, the number of the rotating block, extension plate, fixed arm, support block, extrusion wheel, diverter pipe, connecting hose and floating water bag is four, and the four rotating blocks, extension plate, fixed arm, support block, extrusion wheel, diverter pipe, connecting hose and floating water bag are distributed in a ring on the outside of the lifting plate, so that the four rotating blocks, extension plate, fixed arm, support block, extrusion wheel, diverter pipe, connecting hose and floating water bag can work at the same time.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when the steel truss drilling platform needs to be moved to a specified position in the water as a whole, the hydraulic lifting rod is controlled to work, and when the hydraulic lifting rod is working, the lifting plate is pushed to slide downward on the outer wall of the positioning box, and the lifting frame on the lifting plate descends at the same time, and when the lifting frame descends, the rotating block and the extension plate are pushed to make the bottom of the extension plate contact the top of the extrusion wheel, and at this time, the extrusion wheel slides on the bottom of the extension plate, and makes the extension plate, the rotating block, the lifting frame and the lifting plate on the same horizontal line, and forms a new contact surface, and since the number of the rotating blocks and the extension plates are four, the contact surface is larger, and when the steel truss drilling platform and the positioning box are in the water, since the bottom of the extension plate, the rotating block, the lifting frame and the lifting plate contact the water surface, a larger buoyancy can be provided, and it is more labor-saving when moving the steel truss drilling platform; When the lifting plate needs to move down, the lifting plate squeezes the airbag, and at the same time, the air in the airbag is introduced into the diversion pipe through the extension pipe rack, and finally introduced into the floating water bag from the connecting hose, so that air enters the floating water bag. Since the extension plate, the rotating block, the lifting frame and the lifting plate form a new plane, the floating water bag is located on the top surface of the extension plate, which can increase the buoyancy of the extension plate in the water, making it easier to move the steel truss drilling platform in the water; When the steel truss drilling platform and the positioning box need to be fixed, the hydraulic lifting rod is controlled to drive the lifting plate to rise. At this time, the lifting frame on the lifting plate pulls the rotating block, so that the rotating block drives the extension plate to rise. At the same time, the bottom of the extension plate slides on the top of the extrusion wheel, so that the extension plate can be stored outside the positioning box. At this time, the solenoid valve at the bottom of the back of the airbag is opened. At the same time, since the bottom of the lifting plate is separated from the top of the airbag, the air in the floating water bag is introduced into the airbag through the connecting hose, the shunt pipe and the extension pipe rack, so that the air in the airbag is discharged and water is allowed to enter the airbag, which can avoid the subsequent difficulty in installation due to the presence of a large amount of air in the airbag.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-4 The present invention provides a technical solution: a self-floating steel truss drilling platform structure, including a steel truss drilling platform 1, a driving component 3, an adjustment component 4 and a self-floating component 5, and a positioning box 2 is fixedly connected to the four corners of the bottom of the steel truss drilling platform 1.

[0019] Wherein, the driving component 3 comprises: The fixing plate 301 is fixedly connected to the outside of the positioning box 2, the top of the fixing plate 301 is fixedly connected with a hydraulic lifting rod 302, the hydraulic lifting rod 302 has a telescopic end, the telescopic end of the hydraulic lifting rod 302 is fixedly connected with a lifting plate 303, and the outside of the lifting plate 303 is fixedly connected with a lifting frame 304.

[0020] The telescopic end of the hydraulic lifting rod 302 passes through the top of the fixed plate 301 and extends to the lower side of the fixed plate 301 and is fixedly connected to the top of the lifting plate 303. A sliding groove is provided in the lifting plate 303. The lifting plate 303 is slidably connected to the outer wall of the positioning box 2 through the sliding groove, so that the lifting plate 303 can be lifted and lowered on the outer wall of the positioning box 2.

[0021] See also Figure 1-7The present invention provides a technical solution: the adjustment component 4 includes a rotating block 401, an extension plate 402, a fixed arm 403, a support block 404 and an extrusion wheel 405, the rotating block 401 is rotatably connected to the middle part of the lifting frame 304, the extension plate 402 is fixedly connected to the side of the rotating block 401 away from the lifting frame 304, the fixed arm 403 is fixedly connected to the bottom of the outer side of the positioning box 2, the support block 404 is fixedly connected to the top of the fixed arm 403, and the extrusion wheel 405 is rotatably connected to the outer side of the support block 404.

[0022] The self-floating component 5 includes a storage tank 501, an airbag 502, an extension pipe rack 503, a shunt pipe 504, a connecting hose 505 and a floating water bag 506. The storage tank 501 is opened inside the positioning box 2, the airbag 502 is fixedly connected to the bottom of the storage tank 501, the extension pipe rack 503 is fixedly connected to the top of the airbag 502, the shunt pipe 504 is fixedly connected to the side of the extension pipe rack 503 away from the airbag 502, the connecting hose 505 is fixedly connected to the outside of the shunt pipe 504, and the floating water bag 506 is fixedly connected to the end of the connecting hose 505 away from the shunt pipe 504.

[0023] The top of the extrusion wheel 405 is in sliding contact with the bottom of the extension plate 402, so that when the extension plate 402 extrudes the top of the extrusion wheel 405, the extrusion wheel 405 slides at the bottom of the extension plate 402, and the bottom of the extension plate 402 can be supported at the same time. The top of the lifting frame 304 is fixedly connected to a limiting plate, and the limiting plate is used to limit the rotating block 401 when the rotating block 401 rotates.

[0024] A solenoid valve is provided on the back of the airbag 502, and the air and water flow in and out of the airbag can be controlled by providing the solenoid valve.

[0025] The bottom of the extension pipe rack 503 passes through the top of the lifting plate 303 and extends to the lower side of the lifting plate 303 and is fixedly connected to the top of the airbag 502. The extension pipe rack 503 is communicated with the inside of the airbag 502. The bottom of the floating water bag 506 is fixedly connected to the side of the extension plate 402 away from the positioning box 2, so that when air enters the floating water bag 506, it can provide upward buoyancy for the extension plate 402 in the water.

[0026] There are four rotating blocks 401, extension plates 402, fixed arms 403, support blocks 404, extruding wheels 405, shunt pipes 504, connecting hoses 505 and floating bags 506. The four rotating blocks 401, extension plates 402, fixed arms 403, support blocks 404, extruding wheels 405, shunt pipes 504, connecting hoses 505 and floating bags 506 are distributed in a ring outside the lifting plate 303, so that the four rotating blocks 401, extension plates 402, fixed arms 403, support blocks 404, extruding wheels 405, shunt pipes 504, connecting hoses 505 and floating bags 506 can work simultaneously.

[0027] When the steel truss drilling platform needs to be moved to a specified position in the water as a whole, the hydraulic lifting rod 302 is controlled to work. When the hydraulic lifting rod 302 is working, the lifting plate 303 is pushed to slide downward on the outer wall of the positioning box 2, and the lifting frame 304 on the lifting plate 303 is lowered. When the lifting frame 304 is lowered, the rotating block 401 and the extension plate 402 are pushed, so that the bottom of the extension plate 402 contacts the top of the extrusion wheel 405. At this time, the extrusion wheel 405 slides on the bottom of the extension plate 402, and makes the extension plate 402, the rotating block 401, the lifting frame 304 and the lifting plate 303 are on the same horizontal line, and a new contact surface is formed. Since the number of the rotating block 401 and the extension plate 402 is four, the contact surface is larger. When the steel truss drilling platform 1 and the positioning box 2 are in the water, since the bottoms of the extension plate 402, the rotating block 401, the lifting frame 304 and the lifting plate 303 contact the water surface, a large buoyancy can be provided, which is more labor-saving when moving the steel truss drilling platform 1.

[0028] When the lifting plate 303 needs to move downward, the lifting plate 303 squeezes the airbag 502. At the same time, the air in the airbag 502 is introduced into the shunt pipe 504 through the extension pipe rack 503, and finally introduced into the floating water bag 506 from the connecting hose 505, so that air enters the floating water bag 506. Since the extension plate 402, the rotating block 401, the lifting rack 304 and the lifting plate 303 form a new plane, the floating water bag 506 is located on the top surface of the extension plate 402 at this time, which can increase the buoyancy of the extension plate 402 in the water, making it easier for the steel truss drilling platform 1 to move in the water.

[0029] When it is necessary to fix the steel truss drilling platform 1 and the positioning box 2, the hydraulic lifting rod 302 is controlled to drive the lifting plate 303 to rise. At this time, the lifting frame 304 on the lifting plate 303 pulls the rotating block 401, so that the rotating block 401 drives the extension plate 402 to rise. At the same time, the bottom of the extension plate 402 slides on the top of the extrusion wheel 405, so that the extension plate 402 can be stored outside the positioning box 2. At this time, the solenoid valve at the bottom of the back of the airbag 502 is opened. At the same time, since the bottom of the lifting plate 303 is separated from the top of the airbag 502, the air in the floating water bag 506 is introduced into the airbag 502 through the connecting hose 505, the shunt pipe 504 and the extension pipe rack 503, so that the air in the airbag 502 is discharged and water enters the airbag 502, which can avoid the subsequent difficulty in installation due to the presence of a large amount of air in the airbag 502.
