Description

Technical Field

[0001] The invention relates to the field of installation and disassembly tools, and in particular to a lifting vehicle used for live installation and disassembly of a fixed turret in a power station. Background Art

[0002] With the popularization of power systems, electricity has become an indispensable part of people's daily lives. Transformers and other large oil-filled equipment are the core components of my country's ultra-high voltage power transmission and are important carriers of power transmission. Once a fire occurs, it will cause huge economic losses. Turbofan guns are important equipment for fire fighting. They have the ability to spray both foam and water mist fire extinguishing media at the same time. Compared with a single fire extinguishing medium, the mixed fire extinguishing medium of foam and water mist has a stronger fire extinguishing effect. Therefore, the efficiency of disassembly, assembly and maintenance of turbofan guns directly affects the stability and safety of the power system.

[0003] Most turbofan guns are disassembled and assembled on fixed turrets. Due to the special scene of substations and the large number of live equipment, in the prior art, the disassembly and assembly of turbofan turrets usually requires large cranes and other equipment to lift the turrets and align them. Not only is the operation complicated and time-consuming, but also due to the height limit of the turret, the distance from the top of the crane is difficult to meet the requirements of live safety operations in the substation. Disassembly and assembly can only be carried out when the substation is overhauled and the power outage time is short and the time interval is long, which is difficult to match the disassembly and assembly time of the turbofan turret. In addition, there are safety hazards in the disassembly and assembly process of the turret, especially in the lifting process. The turret has no fixing device. The turret is prone to flipping, tilting, lateral and unstable center of gravity during lifting, and even the turret is detached from the crane. Therefore, there are great safety hazards, endangering the safety of staff and surrounding people. Moreover, some turrets are installed by installation vehicles, and counterweights are often added to avoid the turret being too heavy and causing the vehicle to roll over, which is prone to safety hazards. At the same time, it is easy to operate within the safe distance of the main transformer lightning arrester. There is a high risk of collision. Summary of the invention

[0024] The beneficial effects of the present invention are that, compared with the prior art, the lifting vehicle for live disassembly and assembly of a fixed turret in a power station provided by the present invention has the following advantages:

[0025] The design of a special lifting vehicle simplifies the installation process of the UHV power station turrets and reduces the reliance on large cranes for installing turrets. The use of a lifting vehicle to disassemble and assemble turrets can avoid dangerous distances with electricity during the disassembly and assembly process. Therefore, the entire installation and disassembly process can be carried out without power outages, without the need for power outages for the station's main transformer, making the installation time more flexible and providing a guarantee for the safe operation of the UHV power station from the side. The use of a lifting vehicle to disassemble and assemble fixed turrets can reduce construction and disassembly time, improve construction efficiency, and help improve the maintenance and inspection of UHV substations. The use of a lifting vehicle to disassemble and assemble fixed turrets can eliminate the offset of the center of gravity during the disassembly and assembly process, avoid tipping, and greatly ensure personnel safety.

[0026] The turret inlet and outlet slot of the device enables the turret to reach the connection position by moving the device without lifting, so that the turret can be directly disassembled without being lifted, which simplifies the disassembly process and improves the disassembly efficiency. At the same time, when the turret is installed, it is connected with the lifted turret through the turret inlet and outlet slot, making the connection more convenient.

[0027] The device fixes the turret in the horizontal direction by locking and fixing two lifting locking hoops, and then connects the turret and the device through the fixing of the turret's lifting platform, lifting limit hoop and lifting hydraulic cylinder, so that the turret can move horizontally and rise and fall with the device, and at the same time, the clamping piece and the outer surface of the turret are fitted by rotating the bolt two on the lifting locking hoop, so that the device fixes the turret in the vertical direction, and the lifting locking hoop realizes bidirectional fixation of the turret in the horizontal and vertical directions, so that the device is more stable when driving the turret to move, and the clamping piece and the outer surface of the turret are fitted and fixed, so that the device can fit tightly on turrets of different radii, thereby improving versatility, and the multilateral clamping further improves the stability of the connection between the device and the turret.

[0028] At the same time, the connection between the turret and the device is in the center of the load-bearing base plate. At the same time, the turret splices two limit hoops through a universal fixed shaft and then fixes them with bolts, which makes it more convenient to realize the connection and fixation between the device and the upper part of the turret. The structure is simple and easy to use. At the same time, the universal fixed shaft and the fixed limit hoop cooperate with each other to limit the free movement of the turret and the turbofan gun in the horizontal direction to prevent the turret from tilting and shifting. The four corners of the upper part of the turret transmit the force to the load-bearing chassis through the universal fixed shaft, so that the force is more uniform and the support is more reliable, so that there is no need to add counterweights when installing and disassembling the turret. At the same time, the gun head can be installed after the turret is connected to the device, which simplifies the installation process.

[0029] In summary, the present invention has obvious advantages in disassembling and assembling fixed turrets in a power station environment, and can save installation time, simplify installation steps, improve turret installation efficiency, and has a promising prospect for promotion.

[0035] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the present invention.

[0036] like Figure 1-4 As shown, embodiment 1 of the present invention provides a lifting vehicle for electrically disassembling and assembling a fixed turret in a power station, and the device includes: heavy-loaded universal wheels 1, an electric-controlled hydraulic pump station 2, a load-bearing chassis 3, a turret inlet and outlet slot 4, a universal fixed shaft 5, a lifting hydraulic cylinder 6, a lifting locking hoop 7 and a fixed limit hoop 8.

[0037] The heavy-duty universal wheel 1 is installed at the bottom of the load-bearing chassis 3, and the heavy-duty universal wheel 1 is used to move the device. A turret inlet and outlet slot 4 is arranged on the front side in the middle of the load-bearing chassis 3. The turret inlet and outlet slot 4 is used to facilitate the movement of the turret 11 to the center of the load-bearing chassis 3, so that when the turret 11 is dismantled, it can directly reach the center of the load-bearing chassis 3 through the turret inlet and outlet slot 4 to be fixed and dismantled, without the need for dismantling by a crane, thereby improving the dismantling efficiency and the safety of dismantling. At the same time, when the turret 11 is installed, the lifted turret 11 is also connected and fixed to the device through the turret inlet and outlet slot 4, so that the connection between the device and the turret 11 is more convenient. A plurality of universal fixed shafts 5 are arranged on the top of the load-bearing chassis 3, and the universal fixed shafts 5 are connected to the fixed limit hoop 8. The fixed limit hoop 8 can clamp and fix the upper part of the turret 11 to prevent the turret 11 from shifting and tilting.

[0038] An electric-controlled hydraulic pump station 2 is arranged at the rear center of the load chassis 3, and four lifting hydraulic cylinders 6 are symmetrically arranged at the center of the load chassis 3, so that the force on the turret 11 is more uniform and reliable when it is lifted. The lifting hydraulic cylinder 6 is connected to the electric-controlled hydraulic pump station 2 through a hydraulic pipeline, so that the electric-controlled hydraulic pump station 2 can increase the power source for the lifting hydraulic cylinder 6;

[0039] The lifting hydraulic cylinder 6 contains a signal receiver, which can remotely receive and execute hydraulic oil delivery commands in conjunction with a remote control to improve safety. A turret inlet and outlet slot 4 is arranged on the front side of the load-carrying chassis 3. The four lifting hydraulic cylinders 6 are fixedly connected to the edge of one end of the turret inlet and outlet slot 4 by bolts. The top of the lifting hydraulic cylinder 6 is connected to the lifting locking hoop 7 by a special joint and can be freely disassembled and assembled.

[0040] like Figure 1 and Figure 4 The lifting locking hoop 7 shown in the figure is a left and right two-piece type, which is in a regular hexagonal structure through a bolt combination. A vertical threaded hole 1 is set on the lifting locking hoop 7, and a lifting platform is set on the upper side of the turret 11 corresponding to the lifting locking hoop 7. A vertical threaded hole 2 that is adaptively matched with the lifting locking hoop 7 is set on the lifting platform. At the same time, a threaded hole 3 that is adaptively matched with the lifting locking hoop 7 is set on the upper part of the lifting hydraulic cylinder 6. Bolts pass through the lifting platform, the lifting locking hoop 7 and the lifting hydraulic cylinder 6 in sequence to fix the three together, so that the vertical fixation of the turret 11 is achieved through a simple structure. The lifting and lowering locking hoop 7 is fixed, and at the same time, a horizontal bolt 12 is set on each side of the lifting and lowering locking hoop 7. The bolt 12 passes through the outer wall of the lifting and lowering locking hoop 7 and installs a clamping piece 13 toward the central end. The clamping piece 13 and the outer surface of the turret 11 are fitted and fixed. By rotating the bolt 12, the clamping piece 13 can fit tightly to turrets 11 with different radii, thereby improving versatility. At the same time, the multilateral clamping further improves the stability of the connection between the device and the turret 11, limits the horizontal and vertical displacement of the turret 11, and enables the device to drive the turret 11 to move and fix.

[0041] The fixed limiting hoop 8 comprises: an upper fixed limiting hoop 81 and a lower fixed limiting hoop 82, wherein the upper fixed limiting hoop 81 is located at the upper part of the lower fixed limiting hoop 82, and the fixed limiting hoop 8 is a two-piece type, which is connected and assembled by bolts 10 to form a regular hexagonal structure.

[0042] The universal fixed shaft 5 includes: an upper fixed shaft 51 and a lower fixed shaft 52, wherein four upper fixed shafts 51 and four lower fixed shafts 52 are symmetrically arranged in the center of the load-bearing chassis 3, so that the turret 11 is evenly stressed during the installation process to avoid the force being concentrated on one side and the turret 11 being offset, wherein the bottom of the upper fixed shaft 51 is fixed to the four corners of the outside of the load-bearing chassis 3 by bolts, and the upper fixed limiting hoop 81 is divided into two left and right pieces, the tops of the two upper fixed shafts 51 on the left are connected to the two corners of the upper fixed limiting hoop 81 on the left, and the tops of the two upper fixed shafts 51 on the right are connected to the two corners of the upper fixed limiting hoop 81 on the right, and the lower fixed limiting hoop 82 is also divided into two left and right pieces, and the bottom of the lower fixed shaft 52 is fixed to the bottom of the upper fixed shaft 51 by bolts at two-thirds of the distance from the center straight line of the load-bearing chassis 3, the tops of the two lower fixed shafts 52 on the left are connected to the two corners of the lower fixed limiting hoop 82 on the left, and the right The tops of the two lower fixed shafts 52 are connected with the two corners of a lower fixed limiting hoop 82 on the right side. The upper fixed shaft 51 and the lower fixed shaft 52 can both rotate and pitch, so that the turret 11 is moved to the middle of the two fixed limiting hoops 8 through the turret inlet and outlet slots 4. The two limiting hoops 8 are spliced ​​together through the universal fixed shaft 5 and then fixed by bolts, which makes it more convenient to connect and fix the device and the turret 11. The structure is simple and easy to use. At the same time, the universal fixed shaft 5 cooperates with the fixed limiting hoop 8 to jointly limit the free movement of the upper part of the turret 11 and the turbofan gun in the horizontal direction to prevent the turret 11 from tilting and deviating. The four corners of the upper part of the turret 11 transmit the force to the load-bearing chassis 3 through the universal fixed shaft 5. The force is more uniform, which can better prevent the turret 11 from deviating and tilting, so that there is no need to add counterweight when installing the turret 11. At the same time, the gun head can be installed after the turret 11 is connected to the device, which simplifies the installation process.

[0043] Preferably, the fixed limit hoop 8 is made of 14b channel steel, with M20 bolts installed on each side, which can be combined into a regular hexagonal structure. Limit rollers 9 and rubber buffer pads are installed on each side of the fixed limit hoop 8. The limit rollers 9 can be in contact with the outer surface of the turret to ensure the flexibility of the tower column in the vertical direction during the lifting process. The fixed limit hoop 8 is used to limit the free movement of the turret and turbofan gun in the horizontal direction.

[0044] The four corners of the heavy-duty universal wheel 1 and the load-bearing chassis 3 are fixedly connected. The preferred size of the load-bearing chassis 3 is 4000×4000mm, and the size of the load-bearing chassis 3 can also be changed according to usage requirements. A driving motor is embedded in the load-bearing chassis 3, and the load-bearing chassis 3 can be remotely controlled to move freely through the heavy-duty universal wheel 1, which reduces personnel participation, reduces labor costs, and increases the safety of the disassembly and assembly process. Four heavy-duty universal wheels 1 are provided at the bottom of the load-bearing chassis 3. The preferred heavy-duty universal wheel 1 adopts the GXTD-250-ASF model, which can bear a load of 25 tons. After the heavy-duty universal wheel 1 is installed with the load-bearing chassis 3, the free movement of the device can be guaranteed, and the heavy-duty universal wheel 1 can be locked and rotated 360°.

[0045] The electronically controlled hydraulic pump station 2 is fixed to the rear side of the load-carrying chassis 3 by bolts. The preferred electronically controlled hydraulic pump station 2 has a rated pressure of 16 MPa, a power of 5.5 kW, and a hydraulic capacity of 200 L. The electronically controlled hydraulic pump station 2 is powered by a battery of the load-carrying chassis 3. The electronically controlled hydraulic pump station 2 and the lifting hydraulic cylinder 6 are connected by a hydraulic pipeline, so that the electronically controlled hydraulic pump station 2 can provide power for the lifting hydraulic cylinder 6, and then control the lifting and lowering of the turret 11 through the lifting hydraulic cylinder 6.

[0046] The turret inlet and outlet groove 4 is located in the middle of the front of the load-carrying chassis 3 and is as wide as the turret. The inner surface of the turret inlet and outlet groove 4 is inlaid with a rubber anti-seismic buffer layer to prevent the device from scratching or bumping against the turret. The end of the turret inlet and outlet groove 4 is located in the center of the load-carrying chassis 3 and is connected to the bottom of the lifting hydraulic cylinder 6 by fixing bolts.

[0047] The working principle of the lifting vehicle for the live disassembly and assembly of a fixed turret of a power station of the present invention is as follows: when installing a fixed turbofan turret, firstly, the lifting hydraulic cylinder 6 is in a non-extended state, so that the left and right lifting locking hoops 7 are separated, the turret 11 is lifted by a crane, the turret 11 is slid into the end along the turret inlet and outlet slot 4, the left and right lifting locking hoops 7 are locked and fixed by bolts, so that the device fixes the turret 11 in the horizontal direction, and at the same time, the clamping piece 13 is fitted with the outer surface of the turret 11 by rotating the bolt 12, so that the device fixes the turret 11 in the vertical direction, so as to realize the horizontal and vertical adjustment of the turret 11. The bidirectional fixation in the vertical direction makes the turret 11 more stable when the device drives it to move. At the same time, the universal fixed shaft 5 is rotated to make the upper fixed limit hoop 81 and the lower fixed limit hoop 82 of the left and right pieces fit together and are fixed by bolts 10, so that the turret 11 is fit and fixed with the fixed limit hoop 8 to prevent the turret 11 from deflecting under gravity or wind force and to prevent the turret from tilting during installation. The lifting platform, lifting hydraulic cylinder 6 and lifting locking hoop 7 of the turret 11 are fixed by bolts, and the horizontal and vertical movement of the turret 11 is further limited by a simple structure, so that the turret 11 can move synchronously with the device. More convenient; utilize the space above the ground of the turret 11 on the device, use a crane or forklift to assemble the turbofan gun head and the turret 11, the four corners of the turret 11 transmit the force to the load-bearing chassis 3 through the universal fixed shaft 5, the force is more even, the support is more reliable, and there is no need to add a counterweight to stabilize the device, so that the turret can be assembled on the device, which improves the installation efficiency and the reliability of the assembly process of the staff, and then the electronically controlled hydraulic pump station 2 starts to control the lifting hydraulic cylinder 6 to slowly rise, so that the turbofan gun rises synchronously; use the heavy-duty universal wheel 1 at the bottom of the device to tow the turret on the device through a tractor or forklift 11 is moved to the designated installation position, and the position of the turret 11 is corrected until the turret 11 is aligned with the pre-buried bolts, and the heavy-loaded universal wheel 1 is locked; the lifting hydraulic cylinder 6 is slowly retracted to lower the turret 11 to the designated elevation and stand steadily on the foundation; the turret 11 is fixed with the pre-buried bolts, matching nuts and fixing pads, and after the installation and alignment of the turret 11 is completed, the pads are fully welded to the bottom plate of the turret 11; an insulated movable scaffold is built, the fixed limit hoop 8 and the lifting locking hoop 7 are removed, the locking buckle on the heavy-loaded universal wheel 1 is opened, and the device is removed from the installation area; the disassembly and assembly process is the opposite of the above process.

[0063] At the same time, the connection between the turret and the device is in the center of the load-bearing base plate. At the same time, the turret splices two limit hoops through a universal fixed shaft and then fixes them with bolts, which makes it more convenient to realize the connection and fixation between the device and the upper part of the turret. The structure is simple and easy to use. At the same time, the universal fixed shaft and the fixed limit hoop cooperate with each other to limit the free movement of the turret and the turbofan gun in the horizontal direction to prevent the turret from tilting and shifting. The four corners of the upper part of the turret transmit the force to the load-bearing chassis through the universal fixed shaft, so that the force is more uniform and the support is more reliable, so that there is no need to add counterweights when installing and disassembling the turret. At the same time, the gun head can be installed after the turret is connected to the device, which simplifies the installation process.

[0064] In summary, the present invention has obvious advantages in disassembling and assembling fixed turrets in a power station environment, and can save installation time, simplify installation steps, improve turret installation efficiency, and has a promising prospect for promotion.
