Technical Field

[0001] This utility model relates to the field of steel bar transportation technology, and in particular to a foldable steel bar transportation rack for building construction projects. Background Technology

[0002] As my country's infrastructure construction continues to advance, the safety and stability of steel bars, a common material in construction, are of paramount importance during transportation.

[0003] Currently, most common steel bar transport racks on the market adopt a simple welded metal frame structure. This structure has obvious defects: on the one hand, its stability is poor, and it is difficult to securely lock the steel bars during transportation, which makes the steel bars prone to slipping or even falling, posing a significant safety hazard during transportation; on the other hand, existing steel bar transport racks are mostly integral structures, and due to the limited space on construction sites, when the transport rack is not in use, it cannot effectively reduce its volume, thus occupying a lot of valuable construction site space. Summary of the Invention

[0004] The purpose of this utility model is to provide a foldable steel bar transport rack for building construction projects, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foldable steel bar transport frame for building construction includes a transport frame body with a receiving groove at its upper end. A fixing mechanism is installed within the receiving groove. Two sets of fixing mechanisms are symmetrically arranged at both ends of the receiving groove. Each fixing mechanism includes a crossbeam with support guide rods fixedly installed at both ends. Multiple sets of support plates are arranged sequentially from bottom to top between the two support guide rods. Each support plate has a sliding sleeve at both ends, which is fitted onto the outer wall of the support guide rod and slides along it. A flipping base is located at both ends of the crossbeam away from the support guide rods. A rotating arm is rotatably mounted on the flipping base, and both sides of the rotating arm are rotatably connected to the sides of the flipping base via rotating shafts. One end of the rotating arm is fixedly connected to the crossbeam and is used to drive the crossbeam to flip around the rotating shaft.

[0007] Preferably, the upper end of the support plate is provided with a plurality of first limiting blocks at equal intervals along its length, wherein the plurality of first limiting blocks form a plurality of first limiting grooves; the lower end of the support plate is provided with a plurality of second limiting blocks at equal intervals along its length, wherein the plurality of second limiting blocks form a plurality of second limiting grooves.

[0008] Preferably, the first limiting block and the second limiting block are vertically staggered at the upper and lower ends of the support plate.

[0009] Preferably, the first limiting block has a first arc-shaped locking surface on one side, and the second limiting block has a second arc-shaped locking surface on one side; the first arc-shaped locking surface and the second arc-shaped locking surface are arranged in opposite directions.

[0010] Preferably, the second limiting groove at the lower end of the support plate is inserted into the first limiting groove at the upper end of the adjacent support plate, for closing the two sets of adjacent support plates so that they fit tightly together.

[0011] Preferably, the second limiting block at the lower end of the support plate and the first limiting block at the upper end of the adjacent support plate form a steel bar fixing cavity for limiting and fixing the steel bar.

[0012] Preferably, the outer wall of the support guide rod is provided with a guide groove along its axial direction, and the inner ring of the sleeve is provided with a limiting slider. The limiting slider is disposed in the guide groove and slides in the guide groove.

[0013] Preferably, the flip base is provided with a limiting block, wherein the limiting block has a positioning groove on the side near the rotating arm to limit the rotation angle of the rotating arm.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model installs a fixing mechanism in the receiving groove, wherein each fixing mechanism is provided with multiple sets of support plates arranged sequentially from bottom to top. The upper and lower ends of the support plates are respectively provided with a first limiting groove composed of a first limiting block and a second limiting groove composed of a second limiting block. Adjacent support plates are inserted into the first limiting groove through the second limiting groove and fit tightly together. At the same time, the second limiting block and the adjacent first limiting block form a steel bar fixing cavity, which can limit and fix the steel bar in all directions and at multiple levels, effectively preventing the steel bar from sliding or falling during transportation and improving transportation safety. By setting a flipping base on the side away from the support guide rod at both ends of the crossbeam, the crossbeam is flipped around the axis of rotation by the rotating arm. When the transport frame is idle, the crossbeam can be flipped, making the structure of the entire transport frame more compact, effectively reducing the volume and reducing the occupation of limited space on the construction site.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Please refer to the following: Figures 1 to 6 To achieve the above objectives, this utility model provides the following technical solution:

[0024] A foldable steel bar transport rack for building construction includes a transport rack body 1. The upper end of the transport rack body 1 has a receiving groove 2, within which a fixing mechanism 3 is installed. Two sets of fixing mechanisms 3 are symmetrically arranged at both ends of the receiving groove 2. Each fixing mechanism 3 includes a crossbeam 301, with support guide rods 302 fixedly installed at both ends of the crossbeam 301. Multiple sets of support plates 303 are arranged sequentially from bottom to top between the two support guide rods 302. Each support plate 303 has sliding sleeves 304 at both ends, which are fitted onto the outer wall of the support guide rod 302 and slide along it. Depending on the specifications and quantity of the steel bars, the sliding sleeves 304 allow for precise adjustment of the steel bars. 04. Sliding on the support guide rod 302 adjusts the spacing between multiple sets of support plates 303 to accommodate the placement requirements of steel bars of different diameters, preventing the steel bars from rolling, sliding, or falling during transportation, and ensuring the safety and stability of steel bar transportation; a flipping base 305 is provided on the side of the crossbeam 301 away from the support guide rod 302 at both ends, and a rotating arm 306 is rotatably mounted on the flipping base 305. The two sides of the rotating arm 306 are rotatably connected to the side of the flipping base 305 through a rotating shaft; one end of the rotating arm 306 is fixedly connected to the crossbeam 301, so that the rotating arm 306 drives the crossbeam 301 to flip around the rotating shaft as the axis; The rotating arm 306 is rotatably connected to the side of the tilting base 305 via a pivot, forming a rotatable mechanical structure. When the rotating arm 306 is subjected to an external force and rotates around the pivot, since the rotating arm 306 is fixedly connected to the crossbeam 301, according to the lever principle and the principle of mechanical transmission, the rotation of the rotating arm 306 will drive the crossbeam 301 to move together, realizing the tilting action of the crossbeam 301. When the transport frame has completed the task of transporting steel bars or needs to be idle for storage, the transport frame is folded. The operator applies an external force to make the rotating arm 306 rotate around the pivot. Since one end of the rotating arm 306 is fixedly connected to the crossbeam 301, the rotating arm... The rotation of 306 will cause the crossbeam 301 to rotate around the pivot. As the crossbeam 301 rotates, the support guide rod 302 and the support plate 303 connected to the support guide rod 302 will also move, eventually folding the entire structure of the transport frame into the receiving slot 2, reducing the space occupied. When the transport frame needs to be used to transport steel bars again, the folded transport frame is unfolded. The operator applies an external force in the opposite direction to that applied during folding, causing the rotating arm 306 to rotate in the opposite direction, which in turn causes the crossbeam 301 to rotate in the opposite direction until the transport frame returns to its initial unfolded state. At this point, the steel bars can be placed and transported again.

[0025] In a preferred embodiment, this utility model can be further configured as follows: Figure 4 , Figure 5 , Figure 6As shown; a plurality of first limiting blocks 307 are equidistantly arranged at the upper end of the support plate 303 along its length, wherein the plurality of first limiting blocks 307 form a plurality of first limiting grooves 308; a plurality of second limiting blocks 309 are equidistantly arranged at the lower end of the support plate 303 along its length, wherein the plurality of second limiting blocks 309 form a plurality of second limiting grooves 310; according to the specifications of the steel bars to be transported, by adjusting the height spacing between adjacent support plates 303, the spacing between adjacent support plates 303 is such that it can ensure that the steel bars can be smoothly placed into the first limiting grooves 308, and that the steel bars have sufficient support and limitation during transportation, without... The steel bars may wobble due to excessive spacing. The operator picks up the steel bars one by one and slowly places one end of each bar into the first limiting groove 308 of the support plate 303. Then, the operator guides the steel bars along the direction of the first limiting groove 308 and places the entire steel bar in the first limiting groove 308 of the multiple support plates 303 to prevent the steel bars from rolling or shifting significantly in the horizontal direction. Next, the second limiting groove 310 set below the adjacent support plate 303 is inserted into the first limiting groove 308. Through the double limiting of the first limiting groove 308 and the second limiting groove 310, the stability of the steel bars on the support plate 303 is enhanced, and the wobbling of the steel bars during placement is reduced.

[0026] In a preferred embodiment, this utility model can be further configured as follows: Figure 6 As shown; the first limiting block 307 and the second limiting block 309 are vertically staggered at the upper and lower ends of the support plate 303; the first limiting block 307 has a first arc-shaped locking surface 311 on one side, and the second limiting block 309 has a second arc-shaped locking surface 312 on one side, with the first arc-shaped locking surface 311 and the second arc-shaped locking surface 312 arranged in opposite directions; the vertical staggered arrangement of the first limiting block 307 and the second limiting block 309 forms a double limiting of the reinforcing bar in both horizontal and vertical directions. This three-dimensional limiting structure can effectively prevent the reinforcing bar from rolling, sliding, or shaking during transportation, ensuring the stability of the reinforcing bar placement; the first arc-shaped locking surface 311 and the second arc-shaped locking surface 312, with their arc shape, closely adhere to the outer wall of the reinforcing bar, further enhancing the stability of the reinforcing bar on the support plate 303, reducing the shaking of the reinforcing bar during placement, and improving the safety of reinforcing bar transportation.

[0027] In a preferred embodiment, this utility model can be further configured as follows: Figure 4 , Figure 5As shown; the second limiting groove 310 provided at the lower end of the support plate 303 is inserted into the first limiting groove 308 opened at the upper end of the adjacent support plate 303, which is used to close the two sets of support plates 303 arranged adjacently, so that they fit tightly together; the second limiting groove 310 is inserted into the first limiting groove 308, and by utilizing the complementary shape of the two, the initial positioning and limiting of the adjacent support plates 303 in the horizontal and vertical directions are realized. This fitting structure can quickly close multiple sets of support plates 303 to reduce the volume of the support plates 303 and save space.

[0028] In a preferred embodiment, this utility model can be further configured as follows: Figure 4 , Figure 5 As shown, the second limiting block 309 at the lower end of the support plate 303 and the first limiting block 307 at the upper end of the adjacent support plate 303 form a rebar fixing cavity 4 for limiting and fixing the rebar. The first limiting block 307 and the second limiting block 309 cooperate with each other to form a rebar fixing cavity 4 that conforms to the shape of the rebar. The rebar fixing cavity 4 limits the rebar from multiple directions, which can effectively prevent the rebar from rolling and sliding in the horizontal direction and jumping in the vertical direction, thus ensuring the stable placement of the rebar on the transport frame.

[0029] In a preferred embodiment, this utility model can be further configured as follows: Figure 4 , Figure 6 As shown, the outer wall of the support guide rod 302 has a guide groove 5 along its axial direction, and the inner ring of the sleeve 304 has a limiting slider 6. The limiting slider 6 is set in the guide groove 5 and slides within the guide groove 5. The guide groove 5 on the outer wall of the support guide rod 302 provides precise guidance and positioning for the installation of the sleeve 304. Through the shape and size limitation of the guide groove 5, the sleeve 304 can accurately find the correct position during the installation process, ensuring that the limiting slider 6 can smoothly enter the guide groove 5, thereby realizing the correct connection between the sleeve 304 and the support guide rod 302. When the limiting slider 6 enters the guide groove 5, the two side walls of the guide groove 5 play a preliminary limiting role on the limiting slider 6, preventing the sleeve 304 from rotating radially on the support guide rod 302, ensuring that the sleeve 304 can only slide along the axial direction of the support guide rod 302, providing a stable foundation for the subsequent position adjustment of the support plate 303.

[0030] In a preferred embodiment, this utility model can be further configured as follows: Figure 4 , Figure 5As shown; the flipping base 305 is provided with a limiting block 7, wherein the limiting block 7 has a positioning groove 8 on the side near the rotating arm 306 to limit the rotation angle of the rotating arm 306; when the transport frame is idle, the crossbeam 301 can be flipped, making the structure of the entire transport frame more compact, effectively reducing the volume and reducing the occupation of limited space on the construction site; the setting of the limiting block 7 on the flipping base 305, and the positioning groove 8 on the side of the limiting block 7 near the rotating arm 306, this structure sets a clear boundary for the rotation of the rotating arm 306. When the rotating arm 306 rotates to a certain angle, the positioning groove 8 can block and limit it; when the rotating arm 306 rotates to the maximum angle, the positioning groove 8 on the limiting block 7 produces a mechanical blocking effect on the rotating arm 306 through its side wall, preventing the rotating arm 306 from continuing to rotate, and limiting the rotation angle of the rotating arm 306. This not only makes it convenient for operators to control the degree of flipping of the crossbeam 301, but also ensures the stability of the transport frame structure in normal use and folded state.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
