Description

Technical Field

[0001] This utility model relates to the field of precast beam entry and exit technology, and in particular to a precast beam factory entry and exit classification and identification device. Background Technology

[0002] Precast beams are beams that are prefabricated in a factory and then transported to the construction site for installation and fixation according to the design requirements. After the precast beams are produced, they are often stored in a warehouse to prevent damage during construction, and then released to the construction site when needed.

[0003] When producing precast beams, factories need to manufacture beams of different specifications according to construction drawings. Upon arrival at the warehouse, the precast beams need to be categorized and marked according to their dimensions to facilitate orderly release according to construction needs. A common method for identification and categorization during warehouse entry and exit is for workers to use a measuring tape to measure the beams. After obtaining the results, an identification tag is affixed to the end of the beam to record its dimensions. However, because precast beams are relatively large, workers are prone to measurement errors due to the placement of the measuring tape, and the need to climb up and down to measure the beams increases the risk and compromises their safety. Utility Model Content

[0004] The purpose of this application is to provide a precast beam factory entry and exit classification and identification device to solve the problem mentioned in the background art. The common identification and classification method for precast beams when entering and leaving the warehouse is that workers use a measuring tape to measure the size of the precast beams. After obtaining the result, an identification tag is pasted on the end of the precast beam to record the size information. Because the size of the precast beams is large, the measurement error is easily caused by the placement of the measuring tape. Moreover, workers need to climb up and down to complete the measurement of the size of the precast beams, which increases the risk and is not conducive to their own safety.

[0005] To achieve the above objectives, this application provides the following technical solution: a precast beam factory inbound / outbound classification and identification device, comprising a carrier plate, a connecting seat fixed to the right side of the carrier plate, a first reserved groove opened on the top of the carrier plate, several fixing blocks fixed to the bottom of the carrier plate, a rotating rod fixed through the fixing blocks, rollers rotatably connected to both ends of the rotating rod via bearings, a dual-axis motor and a control module provided at the bottom of the carrier plate, transmission rods fixed to both output shaft ends of the dual-axis motor, a height measuring component provided at the other end of one transmission rod, a width measuring component provided at the other end of the other transmission rod and on the height measuring component, and a length measuring component provided in the first reserved groove, the height measuring component, the width measuring component, and the length measuring component being used to measure the height, width, and length of the precast beam supported on the carrier plate, respectively.

[0006] Furthermore, a reinforcing block is sleeved on the outside of the transmission rod, and the connection between the transmission rod and the reinforcing block is rotatably connected by a bearing. The reinforcing block is fixedly installed on the carrier plate.

[0007] Furthermore, the length measuring component includes two first single-axis motors, both of which are disposed inside the first reserved slot. The output shaft of each first single-axis motor is fixed with a first lead screw, and the other end of the first lead screw is rotatably connected to the inner wall of the first reserved slot via a bearing. A first support plate is threaded onto the first lead screw, and the first support plate slides against the inner wall of the first reserved slot. A first pressing sensor is disposed on the first support plate and is electrically connected to the control module. A first laser rangefinder is disposed on the top of one first support plate, and a first reflecting prism is disposed on the top of the other first support plate. The first laser rangefinder and the first reflecting prism are at the same horizontal height.

[0008] Furthermore, the height measurement component includes a fixed plate and a second reflecting prism. The fixed plate is mounted on one of the transmission rods. A second reserved slot is formed on the fixed plate. A second lead screw is rotatably connected between the upper and lower inner walls of the second reserved slot via bearings. A second single-axis motor is provided at the bottom of the fixed plate. The second lead screw is driven by the second single-axis motor. A sliding plate is threaded onto the second single-axis motor. The sliding plate slides against the inner wall of the second reserved slot.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] 1. In this utility model, the control module can operate the dual-axis motor, which, through the transmission rod, pulls the height measuring component from a horizontal state to a vertical state.

[0013] 2. In this utility model, the control module operates two first single-axis motors to drive two first lead screws, which in turn pull the two first support plates closer together.

This continues until both first pressing sensors have contacted the precast beam. Then, the first laser rangefinder, in conjunction with the first reflecting prism, can determine the length of the precast beam. The control module then controls a second single-axis motor to drive a second lead screw to rotate. The second lead screw, in turn, pulls the slide plate downwards until the second... After the pressure sensor touches the precast beam supported by the carrier plate, the control module controls the second single-axis motor to stop running. The second laser rangefinder, in conjunction with the second reflecting prism, can determine the height of the precast beam. The control module then controls the extension of two electric push rods, causing them to push the two second support plates closer together. Once the third pressure sensor touches the precast beam supported by the carrier plate, the control module controls the corresponding electric push rod to stop running. This process continues until both third pressure sensors have contacted the precast beam. The third reflecting prism, in conjunction with the third laser rangefinder, can then determine the width of the precast beam. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example: Reference Figure 1-7The device shown is a precast beam factory entry and exit classification and identification device, including a carrier plate 1. A connecting seat 2 is fixed on the right side of the carrier plate 1. The connecting seat 2 is used to connect to a traction device, which facilitates the traction device to drive the carrier plate 1 and the precast beams on it into and out of the warehouse. A first reserved groove 3 is opened on the top of the carrier plate 1. Multiple fixing blocks 4 are fixed on the bottom of the carrier plate 1. A rotating rod 5 is fixed through the fixing block 4. Both ends of the rotating rod 5 are rotatably connected to rollers 6 through bearings. The multiple rollers 6 make it more convenient for the carrier plate 1 and the precast beams it supports to enter and exit the warehouse. A dual-axis motor 7 and a control module are set at the bottom of the carrier plate 1. A transmission rod 8 is fixed at both output shaft ends of the dual-axis motor 7. A height measuring component is set at the other end of one transmission rod 8. A width measuring component is set at the other end of the other transmission rod 8 and on the height measuring component. A length measuring component is set in the first reserved groove 3. The height measuring component, the width measuring component, and the length measuring component are used to measure the height, width, and length of the precast beams supported on the carrier plate 1, respectively.

[0025] The control module can operate the dual-axis motor 7, which, with the help of the transmission rod 8, pulls the height measuring component from a horizontal state to a vertical state. In the horizontal state, the height measuring component will not interfere with the hoisting of the precast beam onto the carrier plate 1. The control module controls the length measuring component, height measuring component, and width measuring component to operate in sequence and in an orderly manner, which can measure the size information of the precast beam supported on the carrier plate 1.

[0026] The transmission rod 8 is fitted with a reinforcing block, and the connection between the transmission rod 8 and the reinforcing block is rotatably connected by a bearing. The reinforcing block is fixedly installed on the carrier plate 1. The reinforcing block can improve the stability of the transmission rod 8 during use.

[0027] The length measuring component includes two first single-axis motors 9, both of which are located inside the first reserved slot 3. The output shaft of the first single-axis motor 9 is fixed with a first lead screw 10. The other end of the first lead screw 10 is rotatably connected to the inner wall of the first reserved slot 3 through a bearing. A first support plate 11 is threaded onto the first lead screw 10.

The first laser rangefinder 13 and the first reflecting prism 14 are at the same horizontal height.

[0028] The control module controls two first single-axis motors 9 to drive two first lead screws 10 to pull two first support plates 11 closer together in a lead screw transmission manner. After the first pressing sensor 12 touches the precast beam supported on the carrier plate 1, the control module controls the corresponding first single-axis motor 9 to stop running. After both first pressing sensors 12 have contacted the precast beam, the first laser rangefinder 13 and the first reflecting prism 14 can obtain the length value of the precast beam.

[0029] The height measurement component includes a fixed plate 15 and a second reflecting prism 22. The fixed plate 15 is mounted on one of the transmission rods 8.

A second lead screw 17 is rotatably connected between the upper and lower inner walls of the second reserved groove 16 through a bearing. A second single-axis motor 18 is provided at the bottom of the fixed plate 15. The second lead screw 17 is driven by the second single-axis motor 18.

The second pressure sensor 21 is electrically connected to the control module. A groove for mounting the second reflecting prism 22 is provided on the carrier plate 1. The second laser rangefinder 20 is located directly above the second reflecting prism 22.

[0030] The control module controls the second single-axis motor 18 to drive the second lead screw 17 to rotate. The second lead screw 17 can pull the slide plate 19 down in the form of lead screw transmission until the second pressing sensor 21 touches the precast beam supported on the carrier plate 1. Then the control module controls the second single-axis motor 18 to stop running. The second laser rangefinder 20, together with the second reflecting prism 22, can obtain the height value of the precast beam.

[0031] The width measuring component includes two support plates 23. One support plate 23 is mounted on another transmission rod 8, and the other support plate 23 is mounted on a fixed plate 15. An electric push rod 24 is provided on the support plate 23. A second support plate 25 is fixedly installed at the output end of the electric push rod 24.

A third reflecting prism 27 is provided on the top of one second support plate 25, and a third laser rangefinder 28 is provided on the top of the other second support plate 25. The third reflecting prism 27 and the third laser rangefinder 28 are at the same horizontal height.

[0032] The control module controls the extension of the two electric push rods 24, so that the two electric push rods 24 push the two second support plates 25 together. After the third pressure sensor 26 touches the precast beam supported on the carrier plate 1, the control module controls the corresponding electric push rod 24 to stop running. After both third pressure sensors 26 have contacted the precast beam, the third reflecting prism 27 and the third laser rangefinder 28 can obtain the width value of the precast beam.

[0033] The control module in this embodiment receives signals from the sensor and outputs signals to control the actions of the actuators based on the signals. This control module is existing technology and is commonly used in existing industrial control. For example, it can be a low-power STM32 microcontroller or a Siemens S7-200CN controller.

[0034] Working principle of this utility model:

[0035] Move the carrier plate 1 outside the warehouse and use the hoisting equipment to hoist the precast beam onto the carrier plate 1. At this time, the height measuring component is in a horizontal state and will not interfere with the hoisting of the precast beam. Connect the connecting seat 2 to the traction equipment and use the traction equipment to pull the carrier plate 1 and the precast beam on it into the warehouse. After entering the warehouse, the staff uses the control module to control the dual-axis motor 7 to drive the transmission rod 8 to rotate, so that the transmission rod 8 drives the height measuring component to rotate to a vertical state.

[0036] Workers use a control module to operate two first single-axis motors 9, which drive two first lead screws 10 to pull two first support plates 11 closer together via lead screw transmission. Once the first pressure sensor 12 touches the precast beam supported on the support plate 1, it transmits information to the control module, causing the control module to stop the corresponding first single-axis motor 9. This continues until both first pressure sensors 12 have contacted the precast beam. Then, the first laser rangefinder 13, in conjunction with the first reflecting prism 14, measures the length of the precast beam, which is recorded by the workers. Next, workers use the control module to operate a second single-axis motor 18, which drives a second lead screw 17 to rotate. The second lead screw 17, via lead screw transmission, pulls a sliding plate 19 downwards until the second pressure sensor 21 touches the precast beam supported on the support plate 1. Then, the second pressure sensor 21 transmits information to the control module, which stops the second single-axis motor 18. The second laser rangefinder 20, in conjunction with the second reflecting prism 22, measures the length of the precast beam. The height value is recorded by the staff. Finally, the staff uses the control module to extend the two electric push rods 24, so that the two electric push rods 24 push the two second support plates 25 together. After the third pressure sensor 26 touches the precast beam supported on the carrier plate 1, the third pressure sensor 26 transmits the information to the control module, so that the control module controls the corresponding electric push rod 24 to stop running. After both third pressure sensors 26 have contacted the precast beam, the third reflecting prism 27 and the third laser rangefinder 28 measure the width value of the precast beam and record it by the staff. Afterwards, the staff uses the control module to control the length measuring component, height measuring component and width measuring component to reset, and attach a label to the end of the precast beam to record the size information of the precast beam for easy identification when leaving the warehouse. Finally, the traction equipment is used to transfer the carrier plate 1 and the precast beam on it to the designated location in the warehouse. The hoisting equipment is used to stack the precast beams of the same size and model together to complete the classification and storage of the precast beams.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
