Description

Technical Field

[0001] The utility model relates to the technical field of concrete specimen curing, in particular to a conveying type concrete specimen curing system. Background Art

[0002] The traditional method of curing concrete specimens is to place them on a curing rack in a constant temperature and humidity curing room. This is the most convenient and cheapest way to implement for current construction site laboratories and testing agencies. However, the problems of manpower loss and low space utilization caused by this traditional curing method cannot be ignored. With the current curing method, when storing and taking specimens, testers need to transport them by flatbed trucks and repeatedly move the specimens from the curing rack. For specimens stored on the top and bottom layers of the curing rack, it is more inconvenient for testers to take them. Secondly, since the curing room requires atomized water for curing, the humidity is high, resulting in blurred vision in the room, which is very unfavorable for testers to carry out the handling work. Furthermore, when the specimens on the traditional curing rack reach the test age, testers need to enter the curing room to find their corresponding storage location, and the labor cost increases accordingly. Therefore, a concrete specimen curing system that saves manpower and is more convenient to use is needed.

[0003] In the prior art, Chinese patent document CN111175524A, published (announcement) date: 2020.05.19, discloses a fully automatic intelligent concrete curing and detection system and method, which includes a storage and loading area, a standard curing room, a compressive strength detection area, a storage and unloading conveying device and a control system; the storage and loading area is used to store concrete specimens; the standard curing room is used to provide a constant temperature and humidity curing environment; the compressive strength detection area is used to detect the compressive strength value of the concrete specimens and judge and classify them according to the test results; the storage and unloading conveying device is used to realize the transmission of concrete specimens between the storage and loading area, the standard curing room and the compressive strength testing area; the control system is used to establish a data interactive connection with the storage and loading area, the standard curing room, the compressive strength detection area and the storage and unloading conveying device to implement control. Its characteristics are: the concrete curing system can realize automatic identification, warehousing, curing, outbound storage and compressive strength testing of test pieces, realize 24-hour unmanned operation of the whole process, and reduce labor costs; its disadvantage is that the system still adopts traditional shelf form and uses AGV carts to transport and place test blocks. The transportation and placement method and structure of the test blocks are relatively complicated. Utility Model Content

[0032] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] Embodiment 1:

[0034] See also Figure 1-6 A conveying type concrete specimen curing system includes a first conveying device 100, a second conveying device 200, an operating mechanism 300 and a tray 500. At least one second conveying device 200 is installed above the first conveying device 100 at intervals. The second conveying device 200 is a circulating structure connected end to end. The first conveying device 100 and the second conveying device 200 are installed on one side of the operating mechanism 300. The operating mechanism 300 includes a lifting frame 310, a lifting seat 320 and a telescopic fork 330. The lifting seat 320 is installed on the lifting frame 310, and the telescopic fork 330 is slidably and telescopically installed on the lifting seat 320. The lifting frame 310 is used to drive the lifting seat 320 to move up and down, and the lifting seat 320 drives the telescopic fork 330 to telescopically move through a driving member.

[0035] The utility model transports the concrete specimen 600 through the first conveying device 100, stores the concrete specimen 600 through the second conveying device 200, and carries the concrete specimen 600 on the first conveying device 100 and the second conveying device 200 through the operating mechanism 300. The operating mechanism 300 obtains the pallet 500 and the concrete specimen 600 placed on the pallet 500 from the first conveying device 100 and places them on the second conveying device 200 through the telescopic fork 330, which is used for curing and storing the concrete specimen 600. After that, the operating mechanism 300 obtains the pallet 500 and the concrete specimen 600 placed on the pallet 500 from the second conveying device 200 and places them on the first conveying device 100 through the telescopic fork 330, and the first conveying device 100 can transport the pallet 500 and the concrete specimen 600 placed on the pallet 500 to the downstream laboratory. The method and structure of carrying and placing the concrete test block of the utility model are simpler.

[0036] Specifically, the first conveying device 100 is a roller conveying structure, or Figure 1 The annular conveying structure shown, the second conveying device 200 is an annular conveying structure, and the roller conveying structure and the annular conveying structure are both prior art. The roller conveying structure drives multiple power rollers on the frame to rotate, thereby moving the objects on the power rollers. The annular conveying structure adopts, for example, the structure of a baggage conveyor belt in the prior art.

[0037] Preferably, the second conveying device 200 is provided with multiple layers, thereby improving space utilization.

[0038] Specifically, the pallet 500 is of the prior art, and the pallet 500 includes a top plate and supports located at the bottom of the top plate, so that the telescopic fork 330 can be inserted into the gap between adjacent supports.

[0039] For further information, see Figure 1 , below the second conveying device 200 at the bottom, and a third conveying device 400 is also installed on one side of the first conveying device 100, the third conveying device 400 is a loop structure connected end to end, and one side of the second conveying device 200 and the third conveying device 400 is also installed with an operating mechanism 300. In this way, the space below the second conveying device 200 at the bottom can be utilized to further improve the utilization rate of the space. The operating mechanism 300 here is used to transport the tray 500 and the concrete specimen 600 on the second conveying device 200 to the third conveying device 400, and to transport the tray 500 and the concrete specimen 600 on the third conveying device 400 to the second conveying device 200.

[0040] The third conveying device 400 has the same structure as the second conveying device 200 .

[0041] It should be noted that the second conveying device 200 and the third conveying device 400 adopt a step-by-step operation mode, that is, they operate intermittently at a designed interval, so that it can be ensured that the pallet 500 can be placed at the center of each pallet on the transmission belts of the second conveying device 200 and the third conveying device 400. In this way, when the second conveying device 200 and the third conveying device 400 have multiple folding structures, the pallet 500 will not move relative to the pallet.

[0042] In this embodiment, see Figure 4-6 The lifting frame 310 includes a base 311, a first ball screw 312, a top seat 313, a first motor 314 and a guide rod 315. The top seat 313 is located above the base 311. Two first ball screws 312 and two guide rods 315 are installed diagonally between the top seat 313 and the base 311. The first motor 314 is installed on the top seat 313. The output shaft of the first motor 314 is connected to the first ball screw 312 in a transmission manner. The lifting seat 320 slides with the two guide rods 315 and is screwed with the two first ball screws 312. The first motor 314 rotates to drive the first ball screw 312 to rotate, thereby driving the lifting seat 320 to move up and down.

[0043] Specifically, the first motor 314 is a stepper motor or a servo motor. Between the base 311 and the top seat 313, and on the other three sides located on one side where the telescopic fork 330 extends, the sides can also be connected and fixed.

[0044] In addition to the above structure, the lifting frame 310 can also adopt the low closed height lifting platform structure disclosed in CN203333239U. When applied to the present application, the oil cylinder can be replaced with an electric cylinder to achieve the lifting and positioning of the pallet at different heights.

[0045] See also Figure 6 Two parallel linear guide rails 321 are installed on the lifting seat 320, and a slider is correspondingly installed on the lower side of the telescopic fork 330, and the slider is slidably connected with the linear guide rails 321. Through the above structure, the directional telescopic fork 330 is realized.

[0046] In addition to using a linear slide rail structure to achieve directional telescopic sliding, the telescopic fork 330 can also use a dovetail slide structure similar to that commonly used on machine tools to achieve directional telescopic sliding.

[0047] Continue to see Figure 6The driving member includes a second ball screw 324 and a second motor 325. The lifting seat 320 is provided with a first support seat 322 at one end and a second support seat 323 at the other end. The second motor 325 is provided on the second support seat 323. One end of the second ball screw 324 is rotatably connected to the first support seat 322, and the other end is connected to the output shaft of the second motor 325 for transmission. The telescopic fork 330 is provided with a nut seat, which is screwed with the second ball screw 324. The second motor 325 rotates to drive the second ball screw 324 to rotate, thereby driving the telescopic fork 330 to extend and retract.

[0048] In another embodiment, the driving component is one of an air cylinder, an oil cylinder, and an electric push rod, which is not shown in the figure. The fixed end of the air cylinder, the oil cylinder, or the electric push rod is installed on the lifting seat 320, and the telescopic end is connected to the telescopic fork 330. The telescopic fork 330 is pushed and pulled by the telescopic movement of the telescopic fork 330 through the telescopic movement of the air cylinder, the oil cylinder, or the electric push rod.

[0049] See also Figure 6 The telescopic fork 330 includes two extending arms 331, and the two extending arms 331 are connected to form a whole through a connecting portion 332. Specifically, a nut seat is installed at the bottom of the extending arm 331, and the nut seat is screwed with the second ball screw 324.

[0050] Specifically, the second motor 325 is a stepper motor or a servo motor.

[0051] Embodiment 2:

[0052] See also Figure 2 The system also includes a curing chamber 700, in which the first conveying device 100, the second conveying device 200 and the operating mechanism 300 are located. Both ends of the first conveying device 100 extend out of the curing chamber 700, so that the concrete specimen 600 can be cured in the curing chamber 700.

[0053] When in use, one end of the first conveying device 100 extends to a concrete specimen production or material supply workshop, and the other end extends to a laboratory.

[0054] The working principle or action process of the utility model is as follows:

[0055] See also Figure 1 When there are concrete specimens that need to be cured, the tray 500 and the concrete specimen 600 above are placed on the loading end of the first conveying device 100. The tray 500 and the concrete specimen 600 are conveyed by the first conveying device 100. When the tray 500 and the concrete specimen 600 are moved to the position of the operating mechanism 300 on the left, the first conveying device 100 is paused. At this time, the lifting seat 320 is located at the first conveying device 100, and the telescopic fork 330 is extended. Figure 6The telescopic fork 330 is inserted into the bottom of the pallet 500 , and then the lifting seat 320 rises to a certain height, so that the pallet 500 leaves the first conveying device 100 , and then the telescopic fork 330 retracts to the original point, and the pallet 500 is transferred to the lifting frame 310 .

[0056] Then the lifting seat 320 rises to the second conveying device 200, at which time the second conveying device 200 is in an intermittent stop state, the telescopic fork 330 extends, and the pallet 500 is transferred to the top of the second conveying device 200, and then the lifting seat 320 descends to a certain height, and the telescopic fork 330 retracts, and the pallet 500 and the concrete specimen 600 are placed on the second conveying device 200.

[0057] The test piece on the second transport device 200 can also be transferred to the third transport device 400 , or the test piece on the third transport device 400 can be transferred to the second transport device 200 , through another operating mechanism 300 .

[0058] Similarly, when a concrete specimen 600 reaches the age and needs to be tested, the corresponding tray 500 and concrete specimen 600 on the second conveying device 200 are taken out and placed on the first conveying device 100 through the operating mechanism 300 on the left side. Then, the tray 500 and the concrete specimen 600 are transported to the laboratory for testing through the first conveying device 100.
