Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0065] This utility model provides a storage and conveying system for T-beam web plate test benches, such as... Figures 1-3As shown, the system includes a receiving and moving mechanism 1, a fixed transfer seat 2, a first switching mechanism 3, and a second switching mechanism 4. The trolley 100, which carries a single piece of reinforcing steel frame 200, can reciprocate on the receiving and moving mechanism 1. An unloaded trolley 100 is loaded onto the receiving and moving mechanism 1. The fixed transfer seat 2 is used to store and transfer multiple trolleys 100. The first switching mechanism 3 is located between the receiving and moving mechanism 1 and the fixed transfer seat 2. The first switching mechanism 3 is used to transfer an unloaded trolley 100 from the fixed transfer seat 2 to the receiving and moving mechanism 1, or to transfer a loaded trolley 100 from the receiving and moving mechanism 1 to the fixed transfer seat 2. The second switching mechanism 4 is located at the other end of the fixed transfer seat 2 opposite to the first switching mechanism 3. The second switching mechanism 4 is used to move a loaded trolley 100 out of the fixed transfer seat 2, or to move an unloaded trolley 100 into the fixed transfer seat 2.

[0066] like Figure 2 As shown, the preceding equipment places multiple steel reinforcement skeleton pieces 200 into the slots of the trolley 100 in sequence. The T-beam web plate trolley storage and conveying system provided by this utility model is used to sequentially stack and load steel reinforcement skeleton pieces 200 on the empty trolley 100, and to store and convey them to the next work station for the binding of the continuous reinforcement bars.

[0067] The T-beam web plate storage and conveying system provided by this utility model, by setting up a receiving and moving mechanism 1, allows the unloaded plate 100 to automatically move and receive the single steel reinforcement skeleton pieces 200, reducing the labor intensity of the loading process; by setting up a first switching mechanism 3, a second switching mechanism 4 and a fixed transfer seat 2, the first switching mechanism 3 can move the loaded plate 100 into the fixed transfer seat 2 in sequence, and the fixed transfer seat 2 can store and transfer multiple plate 100s; the second switching mechanism 4 can move the loaded plate 100 out of the fixed transfer seat 2 in sequence for the binding of the continuous reinforcement bars; the second switching mechanism 4 can also move the unloaded plate 100 into the fixed transfer seat 2, thereby realizing the orderly transfer of multiple loaded and unloaded plate 100s, and can simultaneously carry out the loading of the single steel reinforcement skeleton pieces 200 and the subsequent work of binding them in series with continuous reinforcement bars, thus improving the production efficiency of the T-beam web.

[0068] In some embodiments, such as Figure 1 As shown, the receiving and moving mechanism 1, the first switching mechanism 3, the fixed transfer seat 2 and the second switching mechanism 4 are arranged in sequence along the first direction (X direction). There are multiple fixed transfer seats 2, and the multiple fixed transfer seats 2 are arranged in sequence along the second direction (Y direction). Each fixed transfer seat 2 moves along the first direction to set up multiple trolleys 100. The second direction is perpendicular to the first direction.

[0069] like Figure 1In the illustrated embodiment, the trolley 100 is located on the receiving and moving mechanism 1 and carries the steel reinforcement skeleton piece 200. When the trolley 100 moves along the first direction on the receiving and moving mechanism 1, it can move and load materials. After loading, the trolley 100 moves along the receiving and moving mechanism 1 towards the first switching mechanism 3 until it is completely transferred to the first switching mechanism 3. The first switching mechanism 3 can carry the loaded trolley 100 along the second direction and select a fixed transfer seat 2 to transfer the loaded trolley 100 to the fixed transfer seat 2. By using multiple fixed transfer seats 2 arranged along the second direction, multiple rows and columns of trolleys 100 can be arranged simultaneously on the fixed transfer seats 2 in both the first and second directions. In this embodiment of the present invention, the trolley 100 is provided in at least two groups, and each group of multiple trolleys 100 can be divided into multiple segments and stored on multiple fixed transfer seats 2, which is conducive to shortening the layout length of the T-beam web production line and saving space.

[0070] In some embodiments, the receiving and moving mechanism 1 includes a receiving and moving base beam 11, a traveling track 12, first transmission rollers 13, and a traction vehicle 14. The receiving and moving base beam 11 extends along a first direction (X direction); the traveling track 12 is disposed on the receiving and moving base beam 11 and is disposed along the first direction; the first transmission rollers 13 are disposed in pairs on the receiving and moving base beam 11, and multiple pairs of first transmission rollers 13 are spaced apart along the first direction. The trolley 100 is rolled and supported on the first transmission rollers 13; the traction vehicle 14 is slidably disposed on the traveling track 12. When the traction vehicle 14 moves on the traveling track 12, the traction vehicle 14 can pull the trolley 100 to move on the first transmission rollers 13.

[0071] like Figure 4 As shown, in this embodiment, two receiving movable bottom beams 11 are parallel to each other and spaced apart, and connected by a crossbeam. A traveling track 12 for moving the traction vehicle 14 is supported by a crossbeam between the two receiving movable bottom beams 11. First transmission rollers 13 are rolled in pairs on the two receiving movable bottom beams 11 for rolling the load-bearing platform 100. Preferably, the traveling track 12 is set at one end of the receiving movable bottom beam 11. By traction vehicle 14 pulling platform 100, the platform 100 can be moved and positioned intermittently, thereby realizing the moving loading of platform 100, which facilitates the preceding equipment to place the single steel bar skeleton 200 in sequence into the slots on platform 100.

[0072] In some embodiments, the tractor 14 includes a main body 141, a traction drive 142, a lifting drive 143, and a positioning seat 144. The traction drive 142 is configured to drive the main body 141 to move on the travel track 12. The lifting drive 143 is disposed on the main body 141. The positioning seat 144 is disposed at the output end of the lifting drive 143. The lifting drive 143 can drive the lifting movement of the positioning seat 144. When the positioning seat 144 rises, it can be connected and fixed with the trolley 100 to tract the trolley 100.

[0073] like Figure 3 and Figure 4 As shown, the bottom surface of the test bench 100 is provided with guide wheels 101, which are configured to cooperate with the positioning seat 144. When the positioning seat 144 rises, the positioning seat 144 and the guide wheels 101 are connected and fixed, and the traction vehicle 14 can pull the test bench 100 to move. The traction drive component 142 can use a chain drive to drive the main body 141 to move on the travel track 12, such as... Figure 5 As shown, the bottom surface of the main body 141 is provided with V-shaped wheels that cooperate with the walking track 12 to achieve guided movement.

[0074] like Figure 4 The receiving and moving mechanism 1 also includes a first roller drive 15, which is configured to drive the rotation of multiple pairs of first transmission rollers 13, thereby driving the trolley 100 to move on multiple pairs of first transmission rollers 13.

[0075] It should be noted that during the intermittent material loading process of the tractor 14 pulling the platform 100, the platform 100 is always supported on multiple pairs of first transmission rollers 13, which facilitates the traction movement of the platform 100 and reduces frictional resistance during movement. After the platform 100 finishes loading, the tractor 14 stops pulling, the lifting drive 143 drives the positioning seat 144 to descend, the first roller drive 15 starts, and the multiple pairs of first transmission rollers 13 can rotate to drive the platform 100 to move, thereby driving the loaded platform 100 to the first switching mechanism 3. The first roller drive 15 can drive multiple pairs of first transmission rollers 13 simultaneously, or it can drive one set of active transmission wheels in one pair of first transmission rollers 13, and then sequentially drive the other driven transmission wheels. The transmission method can be chain drive or gear drive, etc., which is not limited in this embodiment. Among them, the first roller drive 15 and the traction drive 142 can be motors, and the lifting drive 143 can be cylinders.

[0076] In some embodiments, to save design costs and reduce design difficulty, the first switching mechanism 3 and the second switching mechanism 4 have the same structure, only their positions are different. The first switching mechanism 3 will be described in detail below as an example.

[0077] likeFigure 6 As shown, the first switching mechanism 3 includes a switching base beam 31 and a movable frame 32. The switching base beam 31 extends along a second direction; the movable frame 32 is slidably disposed on the switching base beam 31, with the sliding direction along the second direction. When the movable frame 32 slides along the switching base beam 31, it can selectively connect with multiple fixed transfer seats 2 to move the trolley 100 in or out. It can be understood that the length of the switching base beam 31 along the second direction is not less than the layout width of the multiple fixed transfer seats 2, so that when the movable frame 32 slides on the switching base beam 31, it can be aligned and connected with any one of the fixed transfer seats 2 to transfer the trolley 100. Simultaneously, the movable frame 32 can be aligned and connected with the receiving moving mechanism 1 during movement to transfer the trolley 100.

[0078] In some embodiments, the movable frame 32 includes a base frame 321, a movable drive member 322, second transmission rollers 323, and a second roller drive member 324. The base frame 321 is slidably disposed on the switching base beam 31. The movable drive member 322 is configured to drive the base frame 321 to slide on the switching base beam 31. The second transmission rollers 323 are arranged in pairs on the base frame 321, and multiple pairs of second transmission rollers 323 are spaced apart along a first direction to support the trolley 100. The second roller drive member 324 is disposed on the base frame 321 and is configured to drive the rotation of multiple second transmission rollers 323 to move the trolley 100.

[0079] like Figure 6 As shown in the embodiment of this utility model, the movable drive component 322 is used to drive the base frame 321 to slide on the switching base beam 31. The drive connection method includes, but is not limited to, screw drive connection or gear drive connection. In some embodiments, the movable drive component 322 is located in the middle position of the base frame 321. The movable drive component 322 has two output ends, and each of the two output ends is connected to a connecting rod. A gear is provided at the end of the connecting rod. A rack is provided on the switching base beam 31 to mesh and drive the gear. When the two output ends of the movable drive component 322 rotate, driving the connecting rod to rotate, the gear rotates on the rack, thereby driving the base frame 321 to move. When the movable drive component 322 drives the base frame 321 to align with the receiving moving mechanism 1 or with any fixed transfer seat 2, the trolley 100 can be transferred to the base frame 321 and carried on multiple pairs of second transmission rollers 323. The second transmission rollers 323 are driven to rotate by the second roller drive component 324 to realize the movement drive of the trolley 100.

[0080] In some embodiments, the plurality of fixed transfer seats 2 include a first fixed transfer seat and a second fixed transfer seat. The end of the first fixed transfer seat facing the first switching mechanism 3 can be moved into the trolley 100 in one direction, and the end of the second fixed transfer seat facing the first switching mechanism 3 can be moved out of the trolley 100 in one direction.

[0081] likeFigure 1 As shown, in this embodiment, five fixed transfer seats 2 are provided along the second direction. Four of them are first fixed transfer seats, and the outermost one is a second fixed transfer seat. Each first fixed transfer seat can simultaneously carry four trolleys 100. The trolleys 100 can only move from the first switching mechanism 3 to the first fixed transfer seat in one direction, and reverse movement is restricted. The trolleys 100 on the second fixed transfer seat can be moved in and out in both directions. Through the first switching mechanism 3 and the second switching mechanism 4, the empty trolleys 100 and the loaded trolleys 100 can be arranged and stored in an orderly manner on the fixed transfer seats 2, and moved out and in sequentially. It should be noted that, based on the demand and efficiency of the steel reinforcement cage 200 pieces in the T-beam web production line, this utility model preferably sets up two sets of trolleys 100, each set including eight trolleys 100. The eight trolleys 100 are stored and arranged through two first fixed transfer seats. When loading is required, the rightmost empty trolley 100 on the first fixed transfer seat is first transferred to the second fixed transfer seat through the second switching mechanism 4, and then transferred to the receiving moving mechanism 1 through the first switching mechanism 3 for loading. Correspondingly, the first fixed transfer seat advances the storage of one trolley 100. After loading, the trolley 100 is moved into the leftmost storage position of the first fixed transfer seat via the first switching mechanism 3. After the trolley 100 on the first fixed transfer seat is loaded sequentially, the second switching mechanism 4 can transfer the loaded trolley 100 to the long rib binding station and execute the loading cycle of the next empty trolley 100 on the first fixed transfer seat and the sequential transfer of the loaded trolley 100 to the long rib binding station. In this way, the loading of the trolley 100 and the subsequent long rib binding work can be carried out simultaneously, which greatly improves production efficiency.

[0082] In some embodiments, both the first fixed transfer seat and the second fixed transfer seat include a transfer base beam 21, a third transmission roller 22, and a third roller drive member 23. The transfer base beam 21 extends along a first direction. The third transmission rollers 22 are arranged in pairs on the transfer base beam 21, and multiple pairs of third transmission rollers 22 are spaced apart along the first direction. The third roller drive member 23 is configured to drive the rotation of the third transmission rollers 22 to move the trolley 100.

[0083] like Figure 7 As shown, the two transfer base beams 21 are parallel to each other and spaced apart. Two of the third transmission rollers 22 in each pair are rotatably connected to the two transfer base beams 21. The trolley 100 can be carried on the third transmission rollers 22 and moved and transferred along the first direction. The third roller drive unit 23 can be a chain drive to drive the rotation of multiple third transmission rollers 22, or it can be a gear drive, whichever is not limited.

[0084] It is understood that in this utility model, the spacing between the two first transmission rollers 13 in each pair of first transmission rollers 13, the spacing between the two second transmission rollers 323 in each pair of second transmission rollers 323, and the spacing between the two third transmission rollers 22 in each pair of third transmission rollers 22 all need to be adapted to the width of the trolley 100 in order to stably support the trolley 100 and drive its movement.

[0085] In some embodiments, the multiple pairs of third transmission rollers 22 on the first fixed transfer seat are divided into two groups along the first direction, and two third roller drive members 23 are provided, with the two third roller drive members 23 respectively driving and connecting the two groups of third transmission rollers 22.

[0086] For example Figure 7 , Figure 7 The dashed lines on either side represent the first set of third transmission rollers 22 on the left and the second set of third transmission rollers 22 on the right. The multiple pairs of third transmission rollers 22 on the left can simultaneously support three trolleys 100 and are driven individually by a third roller drive unit 23, moving the trolley 100 from left to right. The multiple pairs on the right support one trolley 100 and are driven individually by another third roller drive unit 23, moving the trolley 100 from left to right to the second switching mechanism 4. By setting two sets of individually driven third transmission rollers 22, the empty or loaded trolley 100 facing the second switching mechanism 4 on the far right can be driven individually to move and transfer, freeing up storage space. The empty trolley 100 can be pre-positioned into the second fixed transfer seat, or the loaded trolley 100 can be moved to the subsequent workstation. When the first switching mechanism 3 transports the loaded trolley 100 to the first fixed transfer seat, because there are empty storage positions, the moving frame 32 of the second switching mechanism 4 does not need to stop at the corresponding first fixed transfer seat. At this time, the moving frame 32 may be transferring an empty or loaded trolley 100. The first switching mechanism 3 and the second switching mechanism 4 can perform the transfer and switching of the trolley 100 simultaneously, improving storage and transportation efficiency; and can reduce the number of times multiple trolleys 100 are moved simultaneously on the first fixed transfer seat, saving power and energy, and can effectively utilize the storage positions on the first fixed transfer seat.

[0087] In some embodiments, the first fixed transfer seat further includes a one-way limiting device 24, which is normally open to limit the trolley 100 to the first fixed transfer seat; the one-way limiting device 24 can be closed when the trolley 100 moves from the first switching mechanism 3 into the first fixed transfer seat.

[0088] like Figure 8 The diagram shows the unidirectional limiting device 24 in its normally open state. Figure 9 and Figure 10The diagram shows the process of the one-way limiting device 24 rotating and closing. When the test bench 100 comes into contact with the one-way limiting device 24, the test bench 100 can rotate and close the one-way limiting device 24, so that the test bench 100 can smoothly move into the first fixed transfer seat. When the test bench 100 is completely moved into the first solid transfer seat and disengaged from the one-way limiting device 24, the one-way limiting device 24 returns to the normally open state, thereby limiting the test bench 100 on the first fixed transfer seat and preventing the test bench 100 on the first fixed transfer seat from moving out in the opposite direction.

[0089] In some embodiments, the one-way limiting device 24 includes a limiting seat 241, a limiting post 242, and a limiting plate 244. The limiting seat 241 is disposed on the bottom beam 21 facing the first switching mechanism 3 at one end. The limiting post 242 is rotatably connected to the limiting seat 241 via a central shaft 243, which is arranged along a second direction. The bottom end of the limiting post 242, facing away from the first switching mechanism 3, can abut against the limiting plate 244 to limit rotation in one direction.

[0090] Combination Figure 9 and Figure 10 As shown, the top of the limiting seat 241 is rotatably connected to the limiting post 242 via the central shaft 243. The center of gravity of the limiting post 242 is biased to one side relative to the central shaft 243. When the limiting post 242 rotates under the action of eccentric force, it can abut against the limiting plate 244 to be in a vertical state. At this time, the top of the limiting post 242 can limit the trolley 100. After the trolley 100 contacts the limiting post 242 and overcomes the eccentric force during the movement, the limiting post 242 rotates in the opposite direction and closes the limit, so that the trolley 100 can be smoothly moved into the first fixed transfer seat.

[0091] In other embodiments, the limiting post 242 is limited by abutting against the limiting plate 244 through eccentric force. Alternatively, a spring can be provided between the limiting post 242 and the limiting plate 244. The bottom end of the limiting post 242 (located below the central shaft 243) abuts against the limiting part under the action of the spring to achieve rotational limitation. When the trolley 100 contacts the top end of the limiting post 242 (located above the central shaft 243) and overcomes the elastic force of the spring, the limiting post 242 rotates and closes the limit, allowing the trolley 100 to move smoothly into the first fixed transfer seat. After the trolley 100 separates from the limiting post 242, the limiting post 242 returns to the open limit state under the action of the spring.

[0092] In a preferred embodiment, the one-way limiting device 24 is detachably connected to the transfer bottom beam 21, thereby enabling the switching between the first fixed transfer seat and the second fixed transfer seat. Alternatively, the limiting plate 244 is detachably connected to the limiting seat 241, and the limiting column 242 can rotate freely around the central axis 243, also enabling the switching between the first fixed transfer seat and the second transfer seat. Furthermore, the position and number of the second fixed transfer seats can be flexibly set by setting the one-way limiting device 24 to meet the efficiency requirements of the T-beam web plate production line.

[0093] This utility model provides a T-beam web plate trolley storage and conveying system, combined with Figure 11 The process of storing and transporting the web plate of the T-beam on the test bench is as follows:

[0094] Set up two groups of test benches, A and B, with 100 test benches in each group, and 8 test benches of 100 in each group. Figure 11 Taking Group A as an example, the T-beam web plate trolley storage and conveying system includes five fixed transfer seats 2, of which the four at the top are the first fixed transfer seats and the one at the bottom is the second fixed transfer seat. Each group of trolleys 100 is divided into two sections and stored in parallel on the two first fixed transfer seats, which shortens the overall layout length of the production line and saves space.

[0095] Taking Group A as an example, initially, eight empty trolleys 100 are sequentially stored on the first fixed transfer seat. Figure 11 Hollow letters indicate unloaded trolley 100, while solid letters indicate trolley 100 after loading. When the eight trolleys B1-B8 of group B are transferred to the next station for the continuous reinforcement binding process, the eight trolleys A1-A8 of group A begin receiving and transferring materials.

[0096] First, the unloaded trolley A1 is fed into the second switching mechanism 4 on the right. The second switching mechanism 4 transfers the unloaded trolley A1 to the second fixed transfer seat below. After continuing to move on the second fixed transfer seat, it is connected by the first switching mechanism 3 and transferred to the receiving moving mechanism 1 for receiving materials.

[0097] After receiving the material, the loaded trolley A1 is transferred to the first fixed transfer seat of the second row via the first switching mechanism 3. At the same time, the first fixed transfer seat of the second row transfers the empty trolley A2 to the second switching mechanism 4 on the right, completing one cycle.

[0098] Similarly, from left to right, the first fixed transfer seat in the second row consists of the loading trolleys A4, A3, A2, and A1. After group B completes the next process and is transferred back to the first fixed transfer seat in the third and fourth rows, the trolley 100 of group A can be sequentially transferred to the next workstation.

[0099] Therefore, it can be understood that when Group B is tying the continuous reinforcing bars at the next work station, Group A is feeding the steel reinforcement cage in 200mm increments, and then they alternate with Group B in a cycle. This allows the feeding process and the continuous reinforcing bar tying process to be carried out simultaneously, which in turn helps to improve the production efficiency of the T-beam web.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
