Description

Technical Field

[0001] The utility model relates to the technical field of mechanical energy storage, and in particular to a steel structure track beam for mechanical energy storage. Background Art

[0002] In the mechanical energy storage system, the process has high requirements on the flatness and longitudinal inclination of the track beam surface in the mass block storage area.

[0003] The track beams in existing mechanical energy storage systems usually use reinforced concrete structures. The on-site pouring construction method makes it difficult for the flatness and inclination of the components to meet the requirements of the process. In addition, in the completed projects, the problem of secondary leveling before equipment installation was encountered because the flatness and inclination did not meet the process requirements. This situation not only caused a huge waste of time, but also increased additional costs.

[0004] In view of the drawbacks of cast-in-place reinforced concrete track beams, a solution of precast concrete track beams was proposed. Precast track beams are precast-cast-in-place composite components. The composite part still needs secondary reinforcement and concrete pouring, and its surface flatness still cannot meet the process requirements. In addition, the mechanical energy storage system is a structure without floor slabs. The construction of the composite part requires special scaffolding and formwork, which has a great impact on the construction period.

[0005] As mentioned above, the existing reinforced concrete track beams cannot meet the process requirements well and are difficult to construct, so it is necessary to find a new form of track beam. Utility Model Content

[0009] Furthermore, the ends of the upper chord, the lower chord and the diagonal web are all fixedly connected to the steel corbels.

[0010] Furthermore, each steel corbel is composed of steel corbel units arranged at equal intervals along the length direction of the steel beam, and the steel corbel units include: stiffening ribs, flange plates, webs and right-angled triangle stiffening ribs, the stiffening ribs fill the internal space of the steel beam, one right-angled side of the right-angled triangle stiffening rib is fixedly connected to the vertical edge of the stiffening rib, a flange plate is horizontally provided on the other right-angled side of the right-angled triangle stiffening rib, a web is provided in the right-angled triangle stiffening rib, and the web is fixedly connected to the flange plate.

[0011] Furthermore, the distance between the upper surface of the flange plate and the upper surface of the steel beam is greater than the wheel height of the RGV trolley, and the web plate and the wheel center of the RGV trolley are located on the same vertical line.

[0012] Furthermore, the distance between the upper surfaces of adjacent steel structure track beams on each floor of the mechanical energy storage system is greater than the width of the RGV trolley, and the distance between two adjacent flange plates of adjacent steel structure track beams on each floor is less than the width of the RGV trolley.

[0022] The technical solution of the utility model is further explained below in conjunction with the accompanying drawings.

[0023] The utility model provides a steel structure track beam for mechanical energy storage. The steel structure track beams are arranged at equal intervals on each floor of the mechanical energy storage system. The steel structure track beam is composed of a steel beam 1, a steel bracket and a connecting steel truss. A steel beam 1 is provided on each side of the connecting steel truss, and a steel bracket is arranged on each steel beam 1. The steel structure track beam for mechanical energy storage of the utility model stores a mass block 10 above the steel beam 1, and runs an RGV trolley 9 on the steel bracket. The height of the wheel 11 of the RGV trolley 9 is less than the distance between the steel beam 1 and the flange plate 3, so that when there is a mass block 10 on the upper surface of the steel beam 1, the RGV trolley 9 can still pass on the steel structure track beam. At the same time, the steel structure track beam of the utility model adopts a construction method of factory prefabrication and on-site installation, which can reduce the construction difficulty and shorten the construction period. The steel track beam has high construction accuracy and can well meet the process requirements for flatness and inclination.

[0024] See also Figure 1-2 The connecting steel truss in the utility model is composed of steel truss units arranged at equal intervals along the length direction of the steel beam 1. The steel truss units include: an upper chord 6, a diagonal member 7 and a lower chord 8. The upper chord 6 is arranged above the lower chord 8, and the upper chord 6 and the lower chord 8 are connected by the diagonal member 7. The ends of the upper chord 6, the lower chord 8 and the diagonal member 7 are all fixedly connected to the steel corbel, thereby forming an effective integral structure together with the steel beam 1. When the RGV trolley 9 runs on the corbel, the torque generated can be converted into a pair of force couples in the two steel beams 1 through the axial force of the upper chord 6, the lower chord 8 and the diagonal member 7, thereby avoiding the torsional deformation of the single steel beam 1.

[0025] Each steel corbel is composed of steel corbel units arranged at equal intervals along the length direction of the steel beam 1. The steel corbel units include: stiffening ribs 2, flange plates 3, webs 4 and right-angled triangle stiffening ribs 5. The stiffening ribs 2 fill the internal space of the steel beam 1. One right-angled side of the right-angled triangle stiffening rib 5 is fixedly connected to the vertical edge of the stiffening rib 2. The flange plates 3 are horizontally arranged on the other right-angled side of the right-angled triangle stiffening rib 5. The webs 4 are arranged in the right-angled triangle stiffening rib 5. The webs 4 and the flange plates 3 are connected by fillet welds to form a T-beam, which is used to bear the running load of the RGV trolley 9.

[0026] The distance between the upper surface of the flange plate 3 and the upper surface of the steel beam 1 is greater than the height of the wheel 11 of the RGV trolley 9, so that when the mass block 10 is arranged on the steel beam 1, the RGV trolley 9 can avoid collision with the mass block on the steel beam 1 during operation, ensuring that the RGV trolley 9 can pass smoothly on the flange plate 3. The web 4 and the center of the wheel 11 of the RGV trolley 9 are located on the same vertical line, so that the vertical load of the RGV trolley 9 can be transmitted to the right-angled triangle stiffening rib 5 and stiffening rib 2 through the T-beam composed of the flange plate 3 and the web 4, and then transmitted to the vertical support member of the mechanical energy storage system through the steel beam 1, making full use of the bearing capacity of the steel beam 1, reducing the amount of materials used, and improving economy.

[0027] The distance between the upper surfaces of adjacent steel structure track beams on each floor of the mechanical energy storage system is greater than the width of the RGV trolley 9. Specifically, the distance between the upper surfaces of adjacent steel structure track beams is the width of the RGV trolley 9 plus 50 mm, and the distance between two adjacent flange plates 3 of adjacent steel structure track beams on each floor is less than the width of the RGV trolley 9, so that the RGV trolley 9 can pass on the flange plates 3.

[0028] The center distance between the steel beams 1 of adjacent steel structure track beams on each floor of the mechanical energy storage system is the span of the mass block 10 minus 200 mm, so that the mass block 10 is set on the upper surface of the steel beam 1 of the adjacent steel structure track beam to ensure that the mass block 10 has sufficient placement width on the steel beam 1.

[0029] In a technical solution of the present utility model, the cross section of the steel beam 1 is one of an H-shaped cross section, a C-shaped cross section and a box-shaped cross section.

[0030] In a technical solution of the utility model, the cross-sections of the upper chord 6, the diagonal web 7 and the lower chord 8 are all selected from one of an L-shaped cross-section, a C-shaped cross-section, a circular cross-section and a box-shaped cross-section.

[0031] like Figure 3The steel beam 1 adopts a box-type section, and the upper chord 6, the diagonal web 7 and the lower chord 8 all adopt circular sections. The steel structure track beam for mechanical energy storage can well resist the torque generated by the operation of the RGV trolley 9 while meeting the requirements of flatness and inclination.

[0032] like Figure 4 The steel beam 1 adopts a C-shaped cross-section, and the upper chord 6, the diagonal web 7 and the lower chord 8 all adopt box-shaped cross-sections. The steel structure track beam for mechanical energy storage can well resist the torque generated by the operation of the RGV trolley 9 while meeting the requirements of flatness and inclination.

[0033] The utility model discloses a steel structure track beam for mechanical energy storage, which is prefabricated in a factory and installed on site, and can greatly improve the flatness of the track beam surface, accurately control the inclination of the track beam, better meet the process requirements, and at the same time reduce the construction difficulty, improve the construction quality, save labor and construction period.
