Description

Technical Field

[0001] The present invention relates to the field of building cement sample detection, and specifically to an automatic pressure detection device for building cement blocks. Background Art

[0002] With the continuous development of China's economy and comprehensive national strength, the operation of all walks of life is becoming more and more standardized. The construction industry is one of the basic industries in China, and its healthy operation is directly related to the sustainable development of the national economy. In recent years, with the gradual establishment and improvement of the market economy in China, the construction industry has also achieved spatial development. While the construction industry is developing rapidly, many problems have also emerged, and the quality of construction projects has become one of the focuses of people's attention. Before the construction of a building project, the contracting unit must obtain an authoritative cement sample qualification test report before it can start construction. The unit responsible for testing the quality of building cement block samples often receives a large number of test samples from various construction companies. The process of testing building cement block samples is generally manual handling and piece-by-piece testing, which increases the labor intensity of the staff. The degree of automation and the testing efficiency of the sample blocks can no longer meet the current large demand for testing building cement block samples; currently, most building cement block samples are directly stacked or placed on fixed shelves. Such a storage method is extremely likely to cause problems such as the confusion of the sample order or the ambiguity of the testing status, making it unclear whether some samples have been tested, and it is also inconvenient to classify and manage a large number of building cement block samples and query information; in addition, the fixed-shelf storage method has a fixed and limited storage capacity and cannot be flexibly adjusted according to the project volume; at the same time, during the manual operation of the testing process, due to different habits of the operators, some tests also show deviations, and the reliability of the sample quality testing is relatively low. Therefore, how to overcome the above-mentioned technical problems and defects has become a key problem to be solved. Summary of the Invention

[0003] The object of the present invention is to overcome the defects described in the background art, so as to realize an automatic pressure detection device for building cement blocks. This device can group the building cement block samples and realize the simultaneous automatic handling in and out of multiple groups of samples, and automatically load and unload the pressure testing machine, significantly reducing the labor intensity of the staff and the potential safety hazards in testing. The degree of automation is greatly improved. In addition, a three-dimensional library with a building-block unit library assembly structure can automatically store the building cement block samples one by one after labeling, with simple and convenient operation. At the same time, the required storage capacity can be assembled according to needs, and the samples can be classified and stored for centralized management.

[0049] In this embodiment, refer to Figures 3 - 5 , the in-out handling device includes an in-out gantry, a lifting and turning beam mechanism, and a sorting mechanism. The bottom of the in-out gantry is fixedly arranged on a horizontal fixed surface. The in-out gantry includes columns and crossbeams, and the columns and crossbeams surround to form an inverted U shape. A fixed flange is arranged at the bottom end of the column, and the bottom end of the column is fixedly arranged on the horizontal fixed surface through the fixed flange. A counterweight is fixedly arranged on the in-out gantry, and the counterweight is arranged on the opposite side of the feeding and turning side of the chute plate, in order to balance the force on the in-out gantry when the building cement blocks slide down from the chute plate.

[0050] In this embodiment, refer to Figure 3 and Figure 4 , the lifting and turning beam mechanism includes a lifting unit and a turning unit. The lifting unit is slidably arranged on both sides of the in-out gantry, and the turning unit is fixedly arranged between the lifting units on the in-out gantry, and the turning unit can rotate clockwise or counterclockwise by a set angle around its own axis while lifting. Next, with the help of the attached drawings, the implementation structures of the lifting unit and the turning unit will be specifically introduced respectively.

The turning cylinder is fixedly arranged inside the lifting unit, one end of the moving beam bracket is installed on the rotating disk of the turning cylinder or is hinged to the inside of the lifting unit, and the other end of the moving beam bracket is fixedly installed with the end of the moving beam. When the turning cylinder rotates by a set angle, it can drive the moving beam to deflect by a set angle accordingly.

[0051] Refer to Figure 4 and Figure 5, in this embodiment, the sorting mechanism is arranged on the flipping unit of the lifting and flipping beam mechanism and is used for the in-warehouse grouping and sorting of building cement blocks. The sorting mechanism includes a sorting flat-top chain, sorting sprockets, a sorting motor, a chute plate, and sensors. The sorting sprockets are fixedly arranged at both ends of the flipping unit, and the sorting flat-top chain is looped around and arranged between the sorting sprockets. The sorting motor is fixedly arranged at one end of the flipping unit, and the sorting motor drives the sorting sprocket at this end to rotate, providing power for the rotation of the sorting flat-top chain. The chute plates are grouped and arranged on the flipping unit at the edge of the sorting flat-top chain. A limiting boss with a width matching that of the chute plate is arranged on the outer sidewall of the sorting flat-top chain. The sensors are fixedly arranged on one side of each group of chute plates and are used to detect the position of the limiting boss to group the cement block samples and align the positions of the chute plates. An upper and lower material guard plate composed of multiple plates is arranged on the flipping unit at the opposite side edge of the sorting flat-top chain where the chute plate is located. Specifically, in this implementation, refer to Figure 5 , the limiting bosses are divided into multiple groups and fixedly arranged on the sorting flat-top chain. The number of limiting bosses arranged side by side in the moving direction of the sorting flat-top chain in each group is 1, 2, 2, 4, 2, 2, 1. When the sorting flat-top chain stops before flipping, 4 limiting bosses arranged side by side are located between each group of chute plates, 2 limiting bosses arranged side by side are located between single chute plates within each group of chute plates, and a single limiting boss is located on the left and right sides of adjacent groups of chute plates. The sensors accurately locate the position of the cement block samples on the sorting flat-top chain corresponding to the chute plates by detecting the number of limiting bosses arranged side by side.

[0052] In this embodiment, refer to Figures 6 - 12 , the modular three-dimensional warehouse is assembled by juxtaposing and / or stacking multiple unit warehouses through inter-warehouse fixing parts. The inter-warehouse fixing parts are rectangular inter-warehouse fixing plates, and the ends or four corners of the inter-warehouse fixing plates are fixedly connected to the warehouse skeletons of adjacent unit warehouses through fasteners. A detachable fixed support is arranged at the bottom of the lowermost unit warehouse, and the fixed support is arranged on the working plane. An inter-warehouse sliding mechanism is fixedly arranged at the joint where two adjacent unit warehouses are butted along their own lengths, and the inter-warehouse sliding mechanism is arranged at the same height as the upper surface of the unit warehouse.

[0053] Refer to Figure 7 and Figure 8, in this embodiment, the unit library includes a library framework, a carrier chain belt mechanism, a chain belt drive mechanism, and a monitoring sensor. The library framework is a rectangular frame. The carrier chain belt mechanism is fixedly arranged on the library framework. The carrier chain belt mechanism includes a carrier flat-top chain, a front driving sprocket, a front driven sprocket, and a rear driven sprocket. The carrier flat-top chain is composed of 3 parallel flat-top chains. The front driving sprocket and the front driven sprocket are both arranged as 3 coaxial sprockets.

The axles of the front driving and driven sprockets and the two sets of rear driven sprockets are fixedly arranged at the ends of the library framework through bearings. The reason for designing the unit library with 3 carrier flat-top chains is that the national standard requires that the same group of samples be detected in 3 pieces together, and the analysis value in the middle of the taken-out samples is used as a reference. One end of the carrier chain belt mechanism where the rear driven sprocket is arranged is provided with a tensioning mechanism. The tensioning mechanism is a conventional bearing tensioner. The axle of the rear driven sprocket is fixedly arranged on the bearing tensioner of the tensioning mechanism. Telescopic pins are arranged at fixed intervals on the carrier flat-top chain. The telescopic pins are common spring telescopic pins in the prior art, and their specific structure will not be described again. The distance between adjacent telescopic pins should be appropriate for placing the width of a cement block sample, so as to separate and position the cement block samples placed on the carrier flat-top chain.

[0054] See Figure 8 , the chain belt drive mechanism is fixedly arranged on one side of the end of the carrier chain belt mechanism. The chain belt drive mechanism includes a chain belt drive motor, a main drive sprocket, and a slave drive sprocket.

The main drive sprocket is installed on the output shaft of the chain belt drive motor. The slave drive sprocket is arranged at the end of one axle of the carrier chain belt mechanism, so that the chain belt drive motor drives the carrier chain belt mechanism to operate. The monitoring sensor is fixedly arranged on the library framework on one side of the end of the carrier chain belt, and is used for controlling the chain belt drive mechanism and counting the number of cement block samples transported in the unit library.

[0055] In order to make the cement block samples move more smoothly between two adjacent docking unit libraries, in this embodiment, see Figures 10 - 12 , the inter-library sliding mechanism includes a fixed bracket, a transition plate, a ball pressing plate, and balls. The fixed bracket is fixedly arranged at the joint of two adjacent docking unit libraries. The transition plate is fixedly arranged between the fixed brackets. A plurality of ball through holes are distributed on the transition plate. Balls are arranged in the ball through holes. The ball pressing plate is provided with limit through holes corresponding to the positions of the ball through holes on the transition plate. The ball pressing plate is fixedly arranged on the upper part of the transition plate for limiting the balls. The upper surface of the balls is set at the same height as the upper surface of the unit library.

[0060] Refer to Figure 14, in this embodiment, the transfer mechanism includes a transfer slide rail, a transfer carriage, a transfer rack, a transfer motor, a transfer turning cylinder, a transfer telescopic cylinder, and a pneumatic gripper.

The transfer turning cylinder, the transfer telescopic cylinder, and the pneumatic gripper are all externally connected to a high-pressure air source.

[0061] In order to realize the operation of the full-automatic system, the industrial control mechanism is a PLC and / or an industrial control computer, which centrally controls the in-out handling device, the modular three-dimensional warehouse, the loading and unloading transfer device, and the pressure test unit to work in coordination. The industrial control computer makes a data table according to the input sample block label. The sample block label can adopt the existing mature RFID identification label. The label input and the industrial control computer to establish a database are mature industrial automation technologies, which will not be elaborated here. At the same time, the industrial control computer also controls the work of the unit warehouse and the three-dimensional warehouse camera to realize the centralized management of the three-dimensional warehouse.

[0062] The working principle of the automatic pressure detection equipment for building cement blocks of the present invention:

[0063] When it is necessary to store the cement block samples in the warehouse, the staff pushes the material transport trolley loaded with multiple cement block samples to one side of the in-out door frame of this device. First, the staff respectively attach identification labels to the cement block samples in groups of three, and input the sample labels into the industrial control computer. The lifting motor of the lifting unit drives the gear-rack structure, so that the lifting carriage drives the moving beam to descend, which is convenient for the staff to place the cement block samples in groups of three on the sorting mechanism on the moving beam. Then, the staff places the cement blocks to be detected at the corresponding positions between the limit bosses on the sorting flat-top chain. At the same time, the sorting flat-top chain is translated under the drive of the sorting motor until all the cement block samples placed on the sorting flat-top chain are aligned with the chute plate to complete the sorting. During or after the sorting, the lifting motor of the lifting unit drives the gear-rack structure, so that the lifting carriage drives the moving beam to rise until it stops after reaching the height of the target bin position in the three-dimensional drawing. Subsequently, the turning cylinder of the turning unit acts, and the turning cylinder drives the moving beam to deflect a certain angle, so that the cement block samples on the sorting flat-top chain roll over along the chute plate and fall into the three-dimensional sample warehouse.

[0064] Build a modular three-dimensional warehouse with a set capacity according to requirements, and assemble it into two parts. One side is the warehouse for untested cement block samples, and the other side is the warehouse for tested cement samples. After the three-dimensional warehouse is assembled, during the use of the equipment, the industrial control computer will define the use type of the warehouse according to the task status. There are three situations, namely transportation warehouse, warehouse to be inspected, and sample retention warehouse. From top to bottom, the top two floors of the three-dimensional warehouse are the areas to be inspected, and the lower floors are the sample retention areas. When the whole machine is in the empty warehouse state, to improve efficiency, the top floor is defined as the transportation warehouse, and the first test samples are directly transported to the automatic loading and unloading equipment end of the pressure test; the second floor is preferably the area to be inspected, and the samples are loaded row by row until the second floor is full; after that, the first floor is defined as the sample retention warehouse, and the workpieces to be inspected are loaded row by row. The sample retention warehouse is loaded by the automatic handling equipment for inbound and outbound. When a row of samples is full, the industrial control computer controls the chain drive mechanism to drive the carrying flat top chain to rotate a station for the whole row, so as to carry out the sample warehousing.

[0065] When the cement block samples in the three-dimensional sample warehouse need to be loaded for the pressure test, the transfer lifting motor of the lifting beam mechanism drives the gear rack structure, so that the transfer lifting carriage drives the lifting beam body to move up and down. At the same time, the transfer lifting motor drives the transfer lifting carriage to slide on the transfer lifting slide rail, and the position is detected by a conventional sensor to align with the untested cement block samples in the three-dimensional warehouse; then, the transfer turning cylinder of the transfer mechanism drives the transfer telescopic cylinder to rotate, so that the pneumatic gripper aligns with the cement block samples in the three-dimensional warehouse. The transfer telescopic cylinder extends, and at the same time the pneumatic gripper opens and grabs the cement block samples. The transfer telescopic cylinder then retracts. Subsequently, the transfer turning cylinder rotates 180°. The transfer motor drives the transfer carriage to slide on the transfer slide rail, so that the cement block samples are aligned with the operating table of the pressure testing machine. Then, the transfer telescopic cylinder extends. After the cement block samples are sent to the designated position of the pressure testing machine, the pneumatic gripper is released, and the transfer telescopic cylinder then retracts to complete the loading operation of the cement block samples; under the control of the hollow computer, the pressure test unit starts to conduct a pressure test on a group of 3 cement block samples. After the pressure test is completed, when it is necessary to unload the cement block samples from the pressure testing machine, the action sequence is opposite to that of the above pressure detection test loading, which will not be elaborated here. The above working process involves conventional processes such as sensor positioning and ranging, which are basic and mature technical means in the industry and will not be described in detail here.

[0066] After the samples have undergone the pressure test, they are sent into the warehouse for tested cement samples by the automatic loading and unloading equipment for the pressure test and stay for up to 72 hours. After the sample retention period expires, the industrial control computer controls the chain drive mechanism to drive the carrying flat top chain to move the group of cement block samples that have expired the sample retention period to the outbound end of the warehouse for tested cement samples, and the samples are transported out of the warehouse by the handling equipment for inbound and outbound; when it is necessary to transport the cement block samples out of the warehouse, the action sequence is opposite to that of the inbound, which will not be elaborated here.
