Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, specifically to a smart beam yard under confined space conditions. Background Technology

[0002] With the continuous development of society and the economy, highway engineering construction has also developed rapidly. The superstructure of highway bridges often uses precast beams, and the quality of precast beam construction directly affects whether the entire bridge project meets the standards. As a crucial component of precast beam construction, the precast beam site bears the responsibility for all precast beam construction tasks in the entire project. It is of paramount importance in the project construction, not only constraining the project schedule but also affecting the overall construction quality of all highway bridge projects. Therefore, the planning and construction of the precast beam site should be carefully organized and arranged at the beginning of the project.

[0003] Generally, to meet the prefabrication requirements of two types of edge beams and one type of center beam, a smart beam yard needs to have at least three independent production lines set up in parallel, for the separate prefabrication of the two types of edge beams and one type of center beam. However, due to the limited land available for mountainous highway construction and the restricted width of the beam yard (26m wide roadbed), it is impossible to set up at least three independent production lines in parallel, resulting in the beam yard being unable to prefabricate the two types of edge beams and one type of center beam. Utility Model Content

[0004] Therefore, it is necessary to provide a smart beam yard under confined space conditions to address the problem that the beam yard width is limited in mountainous areas, which prevents the beam yard from meeting the needs of prefabrication production.

[0005] A smart beam yard under confined space conditions includes: a template sliding assembly system and an automatic material placement system, wherein the template sliding assembly system includes a first production line and a second production line; The first production line includes fixedly arranged high-side templates for the middle beam and high-side templates for the side beams, and movable low-side templates for the middle beams. The movable low-side templates for the middle beams can selectively cooperate with the high-side templates for the middle beams and the high-side templates for the side beams to form a mold cavity. The second production line includes the fixedly arranged middle beam low side template and the side beam low side template, and the movable middle beam high side template, which can selectively cooperate with the middle beam low side template and the side beam low side template to form a mold cavity. The automatic material placement system is used to pour concrete into the mold cavity.

[0006] In one embodiment, the template structures of the template sliding combination system are identical, all including a base and a side mold, with the side mold mounted on the base.

[0007] In one embodiment, when the template is moved and deployed in the template sliding assembly system, the base is slidably deployed along the length of the production line.

[0008] In one embodiment, the side mold is connected to the base via a hydraulic push rod, the extension and retraction of which is used to adjust the height of the side mold.

[0009] In one embodiment, the side mold has a side plate defining the side wall of the precast beam and a top plate defining the cross slope of the precast beam. The top plate and the side plate are hinged together. The side mold is also provided with a cross slope adjusting screw that drives the top plate to rotate.

[0010] In one embodiment, the side mold includes a protective railing to ensure the safety of personnel.

[0011] In one embodiment, the bottom of the mold cavity is provided with a movable platform for supporting the precast beam.

[0012] In one embodiment, the automatic fabric placement system includes a gantry frame and a fabric placement machine. The gantry frame is slidably arranged along the length of the production line, and the fabric placement machine is slidably mounted on the gantry frame. The sliding direction of the fabric placement machine is perpendicular to the production line.

[0013] In one embodiment, the fabric placing machine includes a fabric placing machine body and a fabric placing bin. The fabric placing machine body is slidably mounted on the gantry frame, and the fabric placing bin is connected to the fabric placing machine body via a lifting mechanism.

[0014] In one embodiment, the fabric bin is equipped with a stirring mechanism.

[0015] The intelligent beam yard under the aforementioned confined space conditions can produce three types of beams through the sliding cooperation of the templates on the first and second production lines. Specifically, the middle beam with low side + the side beam with high side = high side beam, the middle beam with high side + the side beam with low side = low side beam, and the middle beam with high side + the middle beam with low side = middle beam. This enables the production of three types of beams on two production lines within a confined space, reducing the beam yard's land area, template and construction personnel input, and achieving good economic and social benefits.

[0022] Please see Figure 1 One embodiment of a smart beam yard under confined space conditions includes a formwork sliding assembly system 10 and an automatic material placement system 20. The formwork sliding assembly system 10 includes a first production line 11 and a second production line 12, which are arranged in parallel.

[0023] Please refer to the following: Figure 2 The first production line 11 includes a high-side formwork for the middle beam, a high-side formwork for the side beams, and a low-side formwork for the middle beam. The high-side formwork for the middle beam and the high-side formwork for the side beams are fixedly arranged, while the low-side formwork for the middle beam is movable. By moving the low-side formwork, it can selectively cooperate with the high-side formwork for the middle beam and the high-side formwork for the side beams to form a mold cavity. The second production line 12 includes a low-side formwork for the middle beam, a low-side formwork for the side beams, and a high-side formwork for the middle beam. The low-side formwork for the middle beam and the low-side formwork for the side beams are fixedly arranged, while the high-side formwork for the middle beam is movable. By moving the high-side formwork, it can selectively cooperate with the low-side formwork for the middle beam and the low-side formwork for the side beams to form a mold cavity.

[0024] The intelligent beam yard under the aforementioned confined space conditions can produce three types of beams through the sliding cooperation of the templates of the first production line 11 and the second production line 12. Specifically, the middle beam with low side + the side beam with high side = high side beam, the middle beam with high side + the side beam with low side = low side beam, and the middle beam with high side + the middle beam with low side = middle beam, thus realizing the production of three types of beams by two production lines under confined space.

[0025] Please refer to the following: Figure 3 and Figure 4 In one embodiment, the template structures of the template sliding combination system 10 are the same, that is, the high side template of the middle beam, the high side template of the side beam, the low side template of the middle beam and the low side template of the side beam have the same structure, only the height and shape of the template are different, thus prefabricating different precast beams 1.

[0026] Specifically, the template sliding assembly system 10 includes a base 13 and side molds 14. The base 13 is supported on the ground, and the side molds 14 are installed on the base 13. When the template is fixed in place, the base 13 is fixed to the ground, achieving a fixed template placement. When the template in the template sliding assembly system 10 is moved, the base 13 slides along the length of the production line. The base 13 can be slidably placed by designing tracks or grooves on the ground, with the base 13 sliding on the tracks or within the grooves.

[0027] In one embodiment, the side mold 14 and the base 13 are connected by a hydraulic jack 15. The extension and retraction of the hydraulic jack 15 is used to adjust the height of the side mold 14 to accommodate the manufacture of precast beams 1 of various sizes. In one embodiment, the side mold 14 has a side plate 16 defining the sidewall of the precast beam 1 and a top plate 17 defining the cross slope of the precast beam 1. The top plate 17 is hinged to the side plate 16. The side mold 14 is also provided with a cross slope adjusting screw 18 that drives the top plate 17 to rotate. The extension and retraction of the cross slope adjusting screw 18 drives the top plate 17 to rotate relative to the side plate 16, thereby enabling the manufacture of precast beams 1 with different cross slopes. A protective railing 19 is provided on the top of the side mold 14 to ensure the safety of personnel standing on top of the side mold 14.

[0028] In one embodiment, the bottom of the mold cavity formed by the template sliding assembly system 10 is provided with a movable platform 30. The movable platform 30 is used to support the precast beam 1 and drive the precast beam 1 to move. The movable platform 30 can carry the reinforcing cage of the precast beam 1 and move it to the pouring position. After the concrete of the precast beam 1 has initially set, the movable platform 30 sends the precast beam 1 into the steam curing zone for curing. After the precast beam 1 has been cured, the movable platform 30 sends the precast beam 1 out.

[0029] Please refer to the following: Figure 5 An automatic concrete placing system 20 is used to pour concrete into the mold cavity. In one embodiment, the automatic concrete placing system 20 includes a gantry frame 21 and a concrete placing machine 22. The gantry frame 21 is slidably arranged along the length of the production line, and the concrete placing machine 22 is slidably mounted on the gantry frame 21. The moving direction of the concrete placing machine 22 is perpendicular to the length of the production line. A first traveling mechanism 211 is provided at the bottom of the gantry frame 21, and a track is provided on the ground, allowing the first traveling mechanism 211 to travel along the track. By sliding the gantry frame 21, the position of the concrete placing machine 22 along the length of the production line is adjusted. By moving the concrete placing machine 22 on the gantry frame 21, it is convenient for the concrete placing machine 22 to feed concrete and pour concrete into the first production line 11 or the second production line 12.

[0030] Please refer to the following: Figure 6 and Figure 7 In one embodiment, the concrete placing boom 22 includes a placing boom body 221 and a placing bin 222. The placing boom body 221 is slidably mounted on the gantry frame 21, and the placing bin 222 is connected to the placing boom body 221 via a lifting mechanism 223. The moving of the entire placing boom 22 is achieved by sliding the placing boom body 221, and the lifting mechanism 223 can raise and lower the placing bin 222, enabling the placing bin 222 to receive concrete and pour it into the mold cavity.

[0031] In one embodiment, the placing boom body 221 is slidably mounted on the gantry frame 21 via a second traveling mechanism 224. It is understood that the first traveling mechanism 211 of the gantry frame 21 and the second traveling mechanism 224 of the placing boom 22 have the same structure, both using a traveling motor to drive traveling rollers to achieve the traveling function. The lifting mechanism 223 can be a winch, with the winch's wire rope connected to the placing bin 222. The winch winds and unwinds the wire rope to raise and lower the placing bin 222. The placing boom body 221 is equipped with a limiting buffer device 225, which prevents the placing bin 222 from colliding with the placing boom body 221 when it rises. Specifically, the limiting buffer device 225 can be a cushioning rubber, etc.

[0032] In one embodiment, a mixing mechanism 226 is provided inside the concrete hopper 222. The mixing mechanism 226 can mix the concrete inside the concrete hopper 222 to ensure the uniformity of the concrete and prevent the concrete from solidifying. The mixing mechanism 226 can adopt a conventional motor mixing shaft structure, which will not be described in detail here.

[0033] The aforementioned smart beam yard under confined space conditions enables the production of three types of beams through two production lines within a confined space, reducing the area occupied by the beam yard, the input of formwork and construction personnel, and achieving good economic and social benefits.
