Description

Technical Field

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

[0002] The track beam is a unique and key structural component in the mechanical energy storage system. The construction quality of the track beam, namely its flatness and inclination, is the key to the stable and safe operation of the mechanical energy storage system.

[0003] Existing mechanical energy storage systems usually use reinforced concrete track beams and use on-site casting, which makes it difficult for the flatness and inclination of the track beams to meet the requirements of the process. In the completed mechanical energy storage projects, the problem of secondary leveling before the installation of the track and other equipment 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 for precast concrete track beams was proposed. Precast track beams are precast-cast-in-place composite components. The cast-in-place part still needs secondary steel bar binding and concrete pouring. There are the following difficulties in practical application: 1) The avoidance process between the protruding bars of the precast components and the main structure steel bars is relatively complicated, which makes the component installation difficult and slow; 2) Adjacent precast components need to be installed in strict accordance with the installation sequence to avoid steel bar collision, which places high demands on the installation team; 3) After the components are in place, the node parts need to be secondary formwork and poured, and the construction quality of the later poured concrete is difficult to guarantee; 4) The precast part is heavy and difficult to hoist; 5) The surface flatness of the cast-in-place part still cannot meet the process requirements well.

[0005] In summary, the existing cast-in-place or prefabricated track beams cannot meet the process requirements well, and there are problems such as great construction difficulty, long construction period, and difficulty in ensuring construction quality. Therefore, it is necessary to find a new form of track beam. Utility Model Content

[0007] To achieve the above technical objectives, the utility model adopts the following technical solutions: a lattice track beam for mechanical energy storage, in which a rectangular frame beam composed of an X-direction frame beam and a Y-direction frame beam is arranged in a grid-like manner on each floor of the mechanical energy storage system, and a plurality of lattice track beam pairs are arranged on the rectangular frame beams of each floor at equal intervals and in the same direction, and the lattice track beams in the lattice track beam pairs are symmetrically arranged on the rectangular frame beams; each lattice track beam comprises: a lattice main beam, a plurality of corbel beams and a track steel beam, the lattice main beam spans the Y-direction frame beam, and the lattice main beam is fixedly connected to the X-direction frame beam through a plurality of corbel beams; the track steel beam is arranged on the inner side of the lattice main beam, and the track steel beam is fixed on the corbel beam.

[0008] Furthermore, the corbel beam spans across the lattice main beam, extends to the X-direction frame beam, and is fixedly connected to the X-direction frame beam.

[0010] Furthermore, the reserved hole is a T-shaped hole. After the corbel beam is hoisted, the pull-out steel plate and the nut are sequentially sleeved on the reserved bolts in the reserved hole.

[0011] Furthermore, the lattice main beam comprises: an upper chord, a web member and a lower chord, the upper chord and the lower chord are both arranged horizontally along the X-direction frame beam direction, and the upper chord and the lower chord are fixed by the web member.

[0012] Furthermore, the webs are arranged in a triangle, an X shape or an N shape.

[0013] Furthermore, the corbel beam spans over the nodes of the web members and is fixed to the nodes of the web members by grouting.

[0014] Furthermore, the web of the track steel beam is arranged at the center of the running wheel of the RGV trolley.

[0015] Furthermore, the distance between the upper surface of the lattice main beam and the upper surface of the track steel beam is greater than the height of the RGV trolley, the distance between the lattice main beams in the center of the lattice track beam is greater than the width of the RGV trolley, and the distance between the track steel beams in the center of the lattice track beam is less than the width of the RGV trolley.

[0016] Furthermore, a mass block is placed on the upper surface of the lattice main beam in the center of the lattice track beam.

DETAILED DESCRIPTION

[0027] The technical solution of the utility model is further explained below in conjunction with the accompanying drawings.

[0028] In each floor of the mechanical energy storage system, a rectangular frame beam composed of an X-direction frame beam 11 and a Y-direction frame beam 12 is arranged in a grid pattern. Figure 1-2 5. A plurality of lattice track beam pairs are arranged on the rectangular frame beams of each floor at equal intervals and in the same direction. The lattice track beams in the lattice track beam pairs are symmetrically arranged on the rectangular frame beams. Each lattice track beam comprises: a lattice main beam, a plurality of corbel beams 4 and a track steel beam 5. The lattice main beam spans the Y-direction frame beam 12, and the lattice main beam is fixedly connected to the X-direction frame beam 11 through a plurality of corbel beams 4. Specifically, the corbel beam 4 spans the lattice main beam, and the gap between the corbel beam 4 and the lattice main beam is filled with water. Slurry filling is used to enhance the integrity and stability of the track beam structure. The corbel beam 4 extends to the X-axis frame beam 11 and is fixedly connected to the X-axis frame beam 11 to prevent the lattice main beam from being subjected to torque when the RGV trolley is running, thereby avoiding local or overall instability caused by torsional deformation due to torsional action and damage or failure of local components due to stress concentration, ensuring the safety and reliability of the track beam; the track steel beam 5 is arranged on the inner side of the lattice main beam, and the track steel beam 5 is fixed on the corbel beam 4. The utility model adopts a lattice main beam, which greatly reduces the dead weight of the track beam compared to the existing cast-in-place concrete track beam and prefabricated reinforced concrete track beam, and is convenient for lifting. In addition, the lattice main beam, corbel beam and track steel beam are all prefabricated in the factory, avoiding complicated steel bar overlap, avoidance and secondary pouring of concrete, thereby greatly improving the flatness of the track beam surface, accurately controlling the inclination of the track beam, and better meeting the process requirements.

[0029] See also Figure 2 In a technical solution of the utility model, a reserved hole 7 is provided on the corbel beam 4, and a reserved anchor bolt 6 is provided at the corresponding position of the X-direction frame beam 11. After the corbel beam 4 is hoisted, the reserved anchor bolt 6 is set in the reserved hole 7, and the reserved hole 7 is grouted and fixed, thereby realizing the fixed connection between the lattice main beam and the X-direction frame beam 11.

[0030] See also Figure 4 When the RGV trolley runs on the track steel beam 5, thereby generating a pull-out force at the connection between the corbel beam 4 and the X-axis frame beam 11, in a technical solution of the utility model, the reserved hole 7 can be set as a T-shaped hole. After the corbel beam 4 is hoisted, the reserved bolt 6 in the reserved hole 7 is sequentially connected with the pull-out steel plate 8 and the nut 9, and the reserved anchor bolt 6 is tied to the corbel beam 4 through the pull-out steel plate 8 and the nut 9 to improve the pull-out bearing capacity of the node.

[0031] See also Figure 3The lattice main beam in the utility model includes: an upper chord 1, a web member 2 and a lower chord 3. The upper chord 1 and the lower chord 3 are both arranged horizontally along the X-direction frame beam 11. The upper chord 1 and the lower chord 3 are fixed by the web member 2. The web member 2 can be arranged in a triangle, an X shape or an N shape. The corbel beam 4 spans across the nodes of the web member 2 and is fixed to the nodes of the web member 2 by grouting.

[0032] In a technical solution of the utility model, when the span or load is small, the lower chord 3 adopts a conventional reinforced concrete structure; when the span or load is large, prestressed tendons 10 can be arranged in the lower chord 3 and prestress can be applied.

[0033] At the same time, in a technical solution of the utility model, see Figure 8 The lattice main beam in the utility model can also be in the form of a hollow truss.

[0034] See also Figure 6 The web of the track steel beam 5 is arranged at the center of the RGV trolley running wheel 14, and the vertical load is directly transferred to the corbel beam 4 through the web of the track steel beam 5, which can simplify the load transfer path and greatly improve the stability of the track steel beam 5. In the utility model, the track steel beam 5 can adopt an H-shaped section, a C-shaped section or a box-shaped section.

[0035] See also Figure 5 In order to enable the RGV trolley 13 to travel on the track steel beam 5 and transport the mass block 15, a mass block 15 is placed on the upper surface of the lattice main beam in the center of the lattice track beam, and the center distance between the lattice main beams in the center of the lattice track beam is the span of the mass block minus 200mm, thereby ensuring that the mass block 15 has sufficient shelf width on the lattice main beam; the distance between the upper surface of the lattice main beam and the upper surface of the track steel beam 5 is greater than the height of the RGV trolley 13, so that the RGV trolley 13 does not collide with the mass block 15 on the lattice main beam during operation, the distance between the lattice main beams in the center of the lattice track beam is greater than the width of the RGV trolley 13, and the distance between the track steel beams 5 in the center of the lattice track beam is less than the width of the RGV trolley 13. Therefore, the distance between the lattice main beams in the center of the lattice track beam in the utility model is the width of the RGV trolley plus 50mm, so that the RGV trolley can run smoothly between adjacent track beams.

[0036] See also Figure 7 In a technical solution of the present invention, if the lattice track beams of the present invention are arranged on both sides of the X-direction frame beam 11, the corbel beams 4 there can be merged, that is, the lattice track beams on both sides of the X-direction frame beam 11 are fixed at the same time by one corbel beam 4, and the corbel beam 4 may not be fixedly connected to the X-direction frame beam 11.

[0037] The utility model has a light deadweight and is easy to connect, so the lattice track beam for mechanical energy storage can reduce the difficulty of hoisting and construction, improve construction quality, save labor and construction period, and has good economic benefits.
