Description

[0001] The invention relates to the technical field of thermal pipeline hoisting in a thermal power plant, in particular to a thermal pipeline hoisting structure in a thermal power plant with a dynamic adjustment function. Background Art

[0002] The thermal pipelines of a thermal power plant are pipeline systems used to transport thermal energy media such as high-temperature steam or hot water in a thermal power plant. These thermal pipelines play a vital role in the operation of a thermal power plant. They are responsible for transporting the high-temperature and high-pressure steam generated by the boiler to the steam turbine, driving the steam turbine to rotate and do work and driving the generator to generate electricity. At the same time, they also send the steam or hot water that has completed the work back to the boiler for reheating.

[0003] During the pipeline laying process, the pipeline is usually lifted by a crane and fixed by components such as wire ropes. It is necessary to manually enter the tunnel to fix and release the pipeline. At the same time, after the pipeline is placed in the tunnel, the two adjacent pipeline ports need to be connected, and the adjustment of direction and position requires manual pushing of the pipeline, which seriously limits the installation efficiency and poses a safety hazard.

[0026] 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.

[0027] Embodiment 1: Figure 1-Figure 5 As shown, the thermal power plant heat pipe hoisting structure with dynamic adjustment function includes two self-propelled mobile chassis 1, and electric lifting positioning rods 20 are arranged at both ends of the self-propelled mobile chassis 1. It should be noted that Figure 1 As shown, the two self-propelled motorized chassis 1 can be driven independently and move in coordination to realize synchronous transportation of the pipeline. The function of the electric lifting and positioning rod 20 is to fix the stopped self-propelled motorized chassis 1 to avoid the problem of violent shaking of the self-propelled motorized chassis 1 when cooperating with the lifting of the pipeline.

[0028] A lifting platform 2 is fixedly connected to the top of the self-propelled motorized chassis 1, a support plate 3 is fixedly connected to the top of the lifting platform 2, a partition frame 4 is fixedly connected to the top of the support plate 3, the lifting platform 2 is an existing device, and the supporting plate 3 fixedly connected to the top is used to lift the partition frame 4, and two arc grooves are formed through the top of the partition frame 4, and an arc slide rail 5 is fixedly connected to the inner side wall of the arc groove, and a sliding bearing seat 6 is slidably connected in the arc slide rail 5, and a lifting seat 7 is arranged directly below the sliding bearing seat 6, and a direction adjustment component 8 is arranged on the top of the partition frame 4.

[0029] A clamping mechanism 9 is provided at the bottom of the lifting seat 7. The clamping mechanism 9 includes multiple groups of transverse rails 901 and multiple groups of horizontal adjustment blocks 902. The transverse rails 901 are symmetrically fixedly connected to the bottom of the lifting seat 7. Both ends of the two corresponding horizontal adjustment blocks 902 are slidably connected in the transverse rails 901. The bottom of the horizontal adjustment block 902 is symmetrically fixedly connected with a bracket 1, and a rotating shaft is movably connected in the bracket 1 through a bearing. A clamping plate 903 is fixed to the bottom of the rotating shaft through spot welding, and a driving rail 904 is fixed to the top of the rotating shaft through spot welding. An electric push rod 1 905 is fixedly installed at the bottom of the horizontal adjustment block 902, and both sides of the output end of the electric push rod 1 905 are fixedly connected with a driving block 1 slidably connected to the driving rail 904.

[0030] An electric push rod 906 is fixedly connected to the center position of the bottom of the lifting seat 7, and an arc-shaped abutment plate 907 is fixedly connected to the bottom end of the electric push rod 906. A bracket 2 is symmetrically fixed to the bottom of the lifting seat 7. A threaded rod 10 and a guide rod are arranged between the two brackets 2. A bidirectional thread is provided on the surface of the threaded rod 10. A threaded groove and a guide groove matching the threaded rod 10 and the guide rod are provided on the side wall of the horizontal adjustment block 902. A motor 11 for driving the threaded rod 10 to rotate is fixedly installed on the outer side of the bracket 2. An electric push cylinder 12 is fixedly connected to the bottom of the sliding bearing seat 6, and the bottom end of the electric push cylinder 12 is fixedly connected to the top of the lifting seat 7.

[0031] During the specific setting, the two self-propelled motorized chassis 1 are synchronously moved to a position close to the pipe to be hoisted. At this time, the two self-propelled motorized chassis 1 are located on both sides of the pipe to be hoisted. Then the electric push cylinder 12 is started, and the electric push cylinder 12 drives the lifting seat 7 to descend synchronously until the corresponding clamping plates 903 are located on both sides of the pipe. The motor 11 drives the threaded rod 10 to rotate, and the bidirectional threads on the surface of the threaded rod 10 cause the two corresponding horizontal adjustment blocks 902 to move synchronously in the opposite direction until the clamping plates 903 are close to the side wall of the pipe. Then the electric push rod 1 905 drives the clamping plates 903 to deflect through the cooperation between the driving block 1 and the driving rail 904.

[0032] The two clamping plates 903 deflect synchronously to clamp the outside of the pipe, and then the second electric push rod 906 drives the arc-shaped abutment plate 907 to move downward, so that the arc-shaped abutment plate 907 abuts against the top of the pipe. The arc-shaped abutment plate 907 cooperates with the clamping plate 903 to achieve adaptive fixed clamping of the pipe, thereby avoiding the problem of shaking during the hoisting and transportation process;

[0033] The direction adjustment component 8 includes multiple groups of positioning frames 801 and limiting slide blocks 802. The positioning frame 801 is fixedly installed on the top of the partition frame 4. The positioning frame 801 is located on both sides of the arc-shaped slide rail 5. The two ends of the limiting slide block 802 are slidably connected in the corresponding positioning frames 801. The top of the limiting slide block 802 is penetrated by a limiting slide groove 803.

[0034] The top of the partition frame 4 is fixedly connected with multiple groups of horizontal electric push rods 804, the output ends of the horizontal electric push rods 804 are fixedly connected to the side walls of the limiting slider 802, the limiting slide groove 803 is slidably connected with the I-shaped slider 805, and the top of the sliding bearing seat 6 is fixedly connected to the bottom of the I-shaped slider 805.

[0035] In the specific setting, when the pipeline is clamped and fixed, and the pipeline is lifted to a specified height by the electric push cylinder 12, two self-propelled motorized chassis 1 travel on the road surface on both sides of the excavated gully until the self-propelled motorized chassis 1 moves with the pipeline to a position close to the pipeline that has been placed in the gully. At this time, the electric push cylinder 12 lowers the pipeline. When the lowering track cannot be closely aligned with the pipeline port in the gully, the horizontal electric push rod 804 on the top of the partition frame 4 is started, and the horizontal electric push rod 804 pushes the limit slider 802 to slide horizontally along the positioning frame 801;

[0036] During the horizontal sliding process of the limit slider 802, the I-shaped slider 805 cooperates with the limit slide groove 803 to drive the bottom sliding bearing seat 6 to slide along the arc-shaped slide rail 5. When both ends of the pipeline are clamped and fixed, the corresponding sliding bearing seat 6 is rotated by the clamping mechanism 9 arranged below. Figure 1 and Figure 4 As shown, the sliding directions of the sliding bearing seats 6 located on both sides of the top of the partition frame 4 are opposite, thereby realizing horizontal deflection of the pipeline. The pipeline after hoisting is first lowered into the gully, and then the direction of the pipeline is dynamically adjusted by the direction adjustment component 8 until it is aligned with the corresponding pipeline port. The clamping mechanism 9 places the pipeline, thereby realizing accurate and rapid hoisting and port alignment of the pipeline;

[0037] The present invention also has a second operation mode for pipeline hoisting, and the operation steps are as follows:

[0038] Two or more self-propelled motorized chassis 1 are used. According to the pipeline hoisting sequence, the first self-propelled motorized chassis 1 sequentially clamps the first pipeline through the clamping mechanism 9, and the second self-propelled motorized chassis 1 sequentially clamps the second pipeline through the clamping mechanism 9. The self-propelled motorized chassis 1 drives the corresponding clamped first pipeline and the second pipeline to move toward the gully. After reaching the designated placement position, the first pipeline and the second pipeline are oriented by the direction adjustment components 8 on the outer sides of their respective self-propelled motorized chassis 1 until the ports of the two pipelines are aligned. Then the two pipelines are synchronously lowered into the gully. Two or more self-propelled motorized chassis 1 are used to carry two or more pipelines at the same time for synchronous hoisting and transportation, and the direction adjustment components 8 are used for synchronous direction adjustment. This not only greatly improves the pipeline hoisting efficiency, but also further improves the pipeline installation efficiency. At the same time, it also solves the problem that the existing pipeline is easily disturbed by the hoisting rope and shakes during the hoisting process, affecting the subsequent pipeline docking.

[0039] Embodiment 2: Figure 1 and Figure 6 As shown, considering that during the pipeline hoisting process, it may take a lot of time for the self-propelled motorized chassis 1 to move from the pipeline stacking position to the pipeline hoisting and lowering position, and considering that there may be bumpy sections on both sides of the gully, which makes it impossible for the self-propelled motorized chassis 1 to move quickly, a turning frame 15 is provided on the side wall of the support plate 3, and the inner side wall of the support plate 3 is fixedly connected to the guide rail 13, and the guide rail 13 is slidably connected to the sliding seat 14, and the side wall of the sliding seat 14 is rotatably connected to the turning frame 15, and a plurality of groups of guide rollers 16 are equidistantly provided on one side of the turning frame 15. It should be noted that one end of the guide roller 16 is connected to an external drive, so as to realize its own rotation and assist the pipeline in transportation, and the guide roller 16 is movably connected to the inner side wall of the turning frame 15 through a bearing.

[0040] A swing rail 17 is fixedly connected to the bottom of the flip frame 15, an electric push rod 3 18 is rotatably installed on the bottom of the side wall of the sliding seat 14, and the output end of the electric push rod 3 18 is fixedly connected to a driving block 2 slidably connected to the swing rail 17, a threaded rod 2 19 is movably connected to the guide rail 13 through a bearing, the threaded rod 2 19 is threadedly connected to the sliding seat 14, and a motor 2 for driving the threaded rod 2 19 to rotate is arranged on the outer side of the guide rail 13.

[0041] During the specific setting, start the motor 2, and the threaded rod 2 19 brought by the motor 2 rotates, so that the sliding seat 14 slides horizontally along the guide rail 13 until the flip frame 15 moves out of the support plate 3, and then start the electric push rod 3 18. The electric push rod 3 18 cooperates with the driving block 2 and the swing rail 17 to flip the flip frame 15 until the flip frame 15 moves to a horizontal state. Then the external lifting machine places the pipeline above the guide roller 16, and the guide roller 16 drives the pipeline to be transported inwardly, so that the clamping mechanism 9 can balance the two ends of the pipeline. Through the auxiliary cooperation of the external lifting mechanism, the lifting efficiency and pipeline docking efficiency of the pipeline are greatly improved.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods.
