Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pumped storage power stations, and in particular to an elbow pipe transport tooling. Background Art
[0002] Pumped storage, also known as energy storage power generation, utilizes electricity generated during periods of low power load to pump water to an upper reservoir. During peak periods, the stored water is then released to a lower reservoir for power generation. This technology converts excess power during periods of low power load into high-value energy during periods of high power load. It is suitable for frequency and phase modulation, can be used to stabilize the power system's frequency and voltage, and is suitable for emergency standby. It can also improve the efficiency of thermal and nuclear power plants within the power system.
[0003] The pump-turbine is the core equipment of a pumped-storage power station. The elbow, a key component of the pump-turbine, is typically composed of multiple pipe sections. Installation of the elbow requires hoisting. Due to plant space limitations, the elbow is typically hoisted to the pit using a bridge crane and then transported to its location using a trolley. However, existing trolleys require high surface flatness, making transport of the elbow prone to tipping and other issues, resulting in poor stability. Therefore, a more stable elbow transport tooling is urgently needed. Utility Model Content
[0004] In view of this, the purpose of this application is to propose an elbow transport tool to solve the related problems mentioned in the background technology.
[0005] Based on the above-mentioned purpose, the present application provides an elbow pipe transport tooling, including: a base; two arc-shaped support plates, respectively installed on the top of the base on two opposite sides along a first horizontal direction, for carrying the elbow pipe, and the axial direction of the elbow pipe is the same as the first horizontal direction; two groups of crawler movers, respectively installed on the bottom of the base on two opposite sides along the first horizontal direction, for driving the base to move along a second horizontal direction, and the first horizontal direction and the second horizontal direction are perpendicular to each other; two trough-type rails, respectively located on the bottom of the base on two opposite sides along the first horizontal direction, for accommodating the crawler-type movers; a driving unit, installed on the base, for driving the crawler-type mover to move along the trough-type rail; a limiting structure, installed at the bottom of the base, located outside the trough-type rail, for limiting the relative position of the base and the trough-type rail.
[0006] Furthermore, the limiting structure includes a fixed shaft connected to the bottom of the base, and a roller is sleeved on the fixed shaft, and the roller abuts against the outer wall of the grooved track.
[0007] Furthermore, there are two fixed shafts, and the two fixed shafts are respectively located on two opposite sides of the same crawler-type mover along the first horizontal direction.
[0008] Furthermore, a group of baffles are respectively provided on two opposite sides of the top of the base along the first horizontal direction. The height of the baffles is higher than the height of the arc-shaped support plate, and the baffles are against the elbow.
[0009] Furthermore, a group of hanging ears are respectively provided on two opposite sides of the top of the base along the second horizontal direction, and the hanging ears are used to connect ropes to bind the elbow.
[0010] Furthermore, a rubber pad is provided on the top of the arc-shaped support plate.
[0011] Furthermore, the driving unit includes two motors, each of which is used to drive a group of the crawler-type movers.
[0012] Furthermore, each group of the crawler-type movers includes two crawler-type movers spaced apart along the second horizontal direction.
[0013] Furthermore, the grooved track includes a plurality of channel steels connected end to end in sequence.
[0014] Furthermore, the base includes a plurality of welded I-beams.

The use of a crawler-type mover reduces friction on the trough track, making transportation more convenient. The crawler-type mover works in conjunction with the trough track, with the sidewalls of the trough track acting as a constraint, ensuring more stable tool movement. The use of a curved support plate in conjunction with the elbow ensures stable placement of the elbow. A position-limiting structure reduces the possibility of tool rollover. This elbow transport tool boasts a simple structure, easy fabrication, excellent stability, high safety, and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The pump-turbine is the core equipment of a pumped-storage power station. The elbow, a key component of the pump-turbine, is typically composed of multiple pipe sections. Installation of the elbow requires hoisting. Due to plant space limitations, the elbow is typically hoisted to the pit using a bridge crane and then transported to its location using a trolley. However, existing trolleys require high surface flatness, making transport of the elbow prone to tipping and other issues, resulting in poor stability. Therefore, a more stable elbow transport tooling is urgently needed.
[0026] Below, through specific embodiments and combined Figures 1 to 4 The technical solution of this application is further described in detail.
[0027] In some embodiments of the present application, a elbow transport tool is provided, such as Figures 1 to 4 As shown, it includes: a base 1; two arc-shaped support plates 2, respectively installed on the top of the base 1 on two opposite sides along the first horizontal direction, for carrying an elbow pipe 3, and the axial direction of the elbow pipe 3 is the same as the first horizontal direction; two groups of crawler movers 4, respectively installed on the bottom of the base 1 on two opposite sides along the first horizontal direction, for driving the base 1 to move along the second horizontal direction, and the first horizontal direction and the second horizontal direction are perpendicular to each other; two trough-type rails 5, respectively located on the bottom of the base 1 on two opposite sides along the first horizontal direction, for accommodating the crawler mover 4; a driving unit 6, installed on the base 1, for driving the crawler mover 4 to move along the trough-type rail 5; a limiting structure 7, installed at the bottom of the base 1, outside the trough-type rail 5, for limiting the relative position of the base 1 and the trough-type rail 5.
[0028] like Figures 1 to 4 As shown, the L1 direction is the first horizontal direction, and the L2 direction is the second horizontal direction.
[0029] The base 1 is the main structure of the elbow transport tooling.
[0030] Two arc-shaped support plates 2 are provided on the base 1. By arranging the arc-shaped support plates 2 and cooperating with the elbow tube 3, the elbow tube 3 can be placed stably; the axial direction of the elbow tube 3 is perpendicular to the moving direction of the tooling, which can reduce the volume of the tooling and reduce costs.
[0031] Two sets of crawler-type movers 4 are installed at the bottom of the base 1, such as crawler-type transport tanks. By adopting the crawler-type movers 4, the friction on the grooved track 5 is reduced, making transportation more convenient.
[0032] A grooved track 5 is provided below the base 1. Through the cooperation between the crawler mover 4 and the grooved track 5, the side walls of the grooved track 5 play a restraining role, making the movement of the tooling more stable.
[0033] A limiting structure 7 is provided at the bottom of the base 1. By providing the limiting structure 7 in cooperation with the grooved track 5, the possibility of the tooling tipping over is reduced.
[0034] The base 1 is also provided with a driving unit 6 for controlling the movement of the tooling.
[0035] The elbow pipe transport tooling has a simple structure, is easy to manufacture, has good stability, is highly safe and has low cost.
[0036] In some embodiments, as Figure 2 As shown, the limiting structure 7 includes a fixed shaft 7 - 1, which is connected to the bottom of the base 1 . A roller 7 - 2 is sleeved on the fixed shaft 7 - 1 , and the roller 7 - 2 abuts against the outer wall of the grooved track 5 .
[0037] like Figure 2 As shown, the limiting structure 7 includes a fixed shaft 7-1 and a roller 7-2 that are rotatably connected. The roller 7-2 and the outer wall of the grooved track 5 are against each other, which can not only play a limiting role but also reduce friction during the movement of the tooling.
[0038] In some embodiments, as Figure 2 As shown, there are two fixed shafts 7 - 1 , and the two fixed shafts 7 - 1 are respectively located on two opposite sides of the same crawler-type mover 4 along the first horizontal direction.
[0039] like Figure 2 As shown, a limiting structure 7 is provided on both sides of the same crawler mover 4 to prevent the tooling from tipping over to the left or right.
[0040] In some embodiments, as Figure 1 As shown, a group of baffles 1 - 1 are respectively provided on two opposite sides of the top of the base 1 along the first horizontal direction. The height of the baffles 1 - 1 is higher than the height of the arc-shaped support plate 2 , and the baffles 1 - 1 abut against the elbow 3 .
[0041] A blocking rod 1 - 1 may also be provided on the base 1 , for example, a blocking rod 1 - 1 may be provided at each of the four corners of the base 1 to further limit the movement of the elbow 3 and provide better stability when the elbow 3 is moved.
[0042] In some embodiments, as Figure 3As shown, a group of hanging ears 1 - 2 are respectively provided on two opposite sides of the top of the base 1 along the second horizontal direction, and the hanging ears 1 - 2 are used to connect ropes to bind the elbow 3.
[0043] like Figure 3 As shown, the base 1 is further provided with hanging ears 1-2. On the one hand, the tooling can be transferred by cooperating with the hanging ears 1-2 and the sling. On the other hand, the two sets of hanging ears 1-2 can be connected with ropes to bind and fix the elbow tube 3, thereby improving the stability when moving the elbow tube 3.
[0044] In some embodiments, a rubber pad is provided on the top of the arc-shaped support plate 2 to avoid damaging the elbow tube 3 and to increase friction, thereby improving stability when moving the elbow tube 3.
[0045] In some embodiments, as Figure 2 As shown, the driving unit 6 includes two motors, each of which is used to drive a group of the crawler-type movers 4, and the driving effect is good.
[0046] In some embodiments, as Figure 3 As shown, each group of the crawler-type movers 4 includes two crawler-type movers 4 spaced apart along the second horizontal direction. For example, a crawler-type mover 4 is respectively arranged at the four corners of the base 1, which has better stability.
[0047] In some embodiments, the grooved track 5 includes a plurality of channel steels connected end to end, which is simple and convenient to manufacture.
[0048] In some embodiments, as Figure 4 As shown, the base 1 includes a plurality of welded I-beams, which has a simple structure and good stability.
[0049] To use the elbow transport tooling: Before transporting the elbow 3, lay channel steel along the transport direction. Then, bolt four crawler movers 4 to the bottom of the base 1. Create a curved support plate 2 based on the dimensions of the elbow 3 and weld it to the base 1. Bolt two motors to the sides of the base 1 and connect them to the same control box. Move the tooling to within the crane's lifting range, hoist the elbow 3 onto the tooling, and use the control box switch or remote control to move the tooling to the installation location.
[0050] The elbow tube transport tooling is driven by dual motors and does not require any external force to achieve self-movement. It is simple to operate during operation, saves time and effort, and is easy to disassemble and assemble, thereby improving the efficiency of transporting and installing the elbow tube 3 and saving construction costs. By replacing the traditional trolley walking mechanism with a crawler mover 4 and channel steel, the channel steel can be directly laid on the ground and can be moved without being fixed, thereby improving the transportation efficiency of the elbow tube 3 and saving construction time and costs. By designing a double-arc support plate 2, in which the curvature of the arc support plate 2 is consistent with the curvature of the elbow tube 3, the arc constraint solves the major problems of the center of gravity and low safety risk of the elbow tube 3 transportation, thereby improving the transportation safety factor of the elbow tube 3.
