Description

Technical Field

[0001] The utility model belongs to the technical field of concrete curing applications, and particularly relates to an automatic loading and unloading robot for a concrete curing chamber. Background Technique

[0002] Concrete curing is to keep the newly poured concrete at a certain temperature and humidity to promote the hydration reaction of cement-based materials, so that its strength and other properties can be fully developed and reach the best state. Among them, preventing the loss of moisture in the concrete, especially the surface layer of the concrete, is an important purpose of curing. For some concretes, water needs to be continuously supplemented during the curing process to keep the concrete in a fully humid environment, thereby promoting the hydration reaction of cement-based materials.

[0003] The concrete curing chamber is suitable for rapid curing of test blocks of ordinary Portland cement, slag cement, pozzolanic cement, and fly ash cement in cement plants, construction sites, scientific research and other units. Through the rapid curing in the concrete curing chamber, the compressive and flexural test results at the ages of 3 days, 7 days, and 28 days (the user can determine the predicted age according to the specific situation) can be predicted within 24 hours, so as to shorten the cement detection cycle and accelerate the cement factory production and use.

[0004] In order to carry out batch curing, placement racks are generally placed in the concrete curing chamber. The placement racks are arranged in multiple layers. In this way, test blocks of different batches can be placed in the curing chamber for curing at the same time, further shortening the detection cycle. However, due to the heavy weight of the test blocks, when the staff place the test blocks, the labor intensity is large, the placement time is long, and they need to climb up and down to place them, which poses a safety hazard. Summary of the Utility Model

[0005] Aiming at the technical problems existing in the taking and placing of test blocks in the curing chamber, the utility model provides an automatic loading and unloading robot for a concrete curing chamber with reasonable design, simple structure, convenient processing and capable of realizing automatic taking and placing of test blocks.

[0006] To achieve the above object, the technical solution adopted by the utility model is: The utility model provides an automatic loading and unloading robot for a concrete curing chamber, including a traveling trolley and a placement table arranged on the traveling trolley. A column is also arranged on the traveling trolley. The columns are arranged near the four corners of the traveling trolley. A double-axis truss mechanism is also arranged between the columns. The double-axis truss mechanism realizes the movement in the X-axis and Y-axis directions. A picking and placing mechanism is arranged on the X-axis of the double-axis truss mechanism. The picking and placing mechanism includes a picking and placing frame arranged on the X-axis and a turning frame arranged on the picking and placing frame. The turning frame is turnably arranged on the picking and placing frame. An electric gripper is arranged at the bottom of the turning frame. The double-axis truss mechanism is arranged on the column in a lifting manner.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0019] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0020] Embodiment 1, as Figures 1 to 3 shown, the purpose of this embodiment is to provide a loading and unloading robot that can reduce the labor intensity of workers and improve the placing efficiency of test blocks. To this end, in order to achieve the above object, the automatic loading and unloading robot for a concrete curing chamber provided in this embodiment includes a traveling trolley 1 and a placing table 11 provided on the traveling trolley 1. The traveling trolley 1 can be an electrically driven remote control vehicle or an AGV trolley. This is because the line is relatively fixed and transportation can be completely achieved by the AGV trolley. The placing table 11 is in a flat plate shape. Since most of the existing test blocks are square and are relatively stable after being placed, the placing table 11 is set to be in a flat plate shape.

[0021] In order to place the test blocks on the placing rack, in this embodiment, a column 12 is further provided on the traveling trolley 1. The column 12 is arranged near the four corners of the traveling trolley 1. A double-axis truss mechanism 2 is further provided between the columns 12. The double-axis truss mechanism 2 realizes the movement in the X-axis 21 and Y-axis 22 directions. The double-axis truss mechanism 2 is a common mechanism in the prior art, and it mainly uses the cooperation of a motor and a rack to realize the movement in the X-axis 21 and Y-axis 22. In this embodiment, the main reason for not using a three-axis truss mechanism is that the height in the curing chamber is limited, and the setting in the Z-axis direction will increase the height of the entire structure, which may affect the use.

[0022] In order to realize the grasping and placing of the test blocks, a picking and placing mechanism is provided on the X-axis 21 of the double-axis truss mechanism 2. Specifically, the picking and placing mechanism includes a picking and placing frame 3 provided on the X-axis 21 and a flipping frame 4 provided on the picking and placing frame 3. The flipping frame 4 is rotatably arranged on the picking and placing frame 3. In this embodiment, the flipping placement of the flipping frame 4 is mainly considered for the problem of the traveling process. It is impossible to only set columns 12 at both ends of the existing placing rack, and the middle column 12 affects the traveling of the X-axis 21. Therefore, the flipping frame 4 is flipped, so that the test block extends out of the traveling trolley 1, thus facilitating the placement of the test block on the placing rack. In this embodiment, considering that the test block is square, an electric gripper 5 is provided at the bottom of the flipping frame 4. It should be noted that, in this embodiment, the electric gripper 5 has a two-claw structure, and a three-claw structure will affect the subsequent placement.

[0023] Considering that the placement rack is arranged in layers, for this reason, the double-axis truss mechanism 2 is arranged on the column 12 in a lifting manner. Specifically, the double-axis truss mechanism 2 is arranged on the column 12 through a lifting mechanism. Since the flipping rack 4 and the electric gripper 5 have a certain height, for this reason, the lifting mechanism can be a lifting cylinder or a lifting electric cylinder. The lifting electric cylinder is preferably considered because the entire trolley adopts an electric structural design, and its implementation is more convenient. In this embodiment, the lifting structure adopts a lifting lead screw structural design, that is, the motor drives the lead screw 13 to rotate. The lead screw 13 is rotatably arranged in the column 12. The column 12 is made of C-shaped steel. A nut seat is arranged on the side wall of the Y-axis 22, and the lead screw nut is arranged in the nut seat. In this way, a lifting mechanism is formed. More specifically, in this embodiment, one motor is used in cooperation with a commutator to realize the simultaneous control of four lead screws 13. The purpose of this setting is to be able to arrange the column 12 at the corner close to the walking trolley 1 without affecting the setting of the walking wheels.

[0024] In order to more conveniently control the flipping of the flipping rack 4, in this embodiment, the picking and placing rack 3 is arranged in an inverted U shape. A flipping shaft 41 is arranged on the top of the flipping rack 4. The flipping shaft 41 is rotatably arranged on the picking and placing rack 3. A flipping motor 42 for flipping the flipping shaft 41 is arranged on the picking and placing rack 3. It should be noted that the flipping rack 4 only needs to achieve a 90° flip.

[0025] Through the above settings, the automatic picking and placing of the test blocks is effectively satisfied, the work efficiency is improved, and the work intensity is reduced.

[0026] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as the content of the technical solution of the present invention is not departed from, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
