Description

Technical Field

[0001] The utility model relates to a material unloading platform for building construction, in particular to an integrated material unloading platform with an overload alarm function. Background Art

[0002] At present, the main load limit monitoring method for cantilever unloading platforms in China is to place a weighing device on the secondary beam of the unloading platform. However, this load limit monitoring method has the following defects:

[0003] Safety hazards in the structure of the weighing scale device: the weighing scale legs are placed in the center of the secondary beam, and springboards are laid on both sides of the weighing scale. The weighing scale is about 100mm higher than the surface of the springboard. There is a large gap between the edge of the weighing scale and the edge of the springboard. Since the unloading platform is at high altitude, there is a safety risk of falling objects falling from the gap and injuring people during construction; since the bearing area of ​​the weighing scale is limited, in actual construction, in order to put more materials, the operators often use wooden beams and multi-layer boards to pad the springboards on both sides to the same height as the weighing scale, and then stack the materials uniformly. This situation not only increases the constant load of the unloading platform, but also inevitably causes distortion of the weighing data of the weighing scale, and then overload and over-limit use occurs, posing a greater safety hazard to construction operations.

[0004] Risk of damage to the weighing scale instrument: Since the weighing scale sensor needs to be connected to a dedicated instrument to output data, in order to facilitate data line access and unloading platform transfer installation, the weighing scale instrument is generally installed on the side of the guardrail on one side of the platform. Since the materials transported in the unloading platform are mostly long, large and heavy materials such as steel pipes, wooden squares and multi-layer boards, during the material lifting process, if you are not careful, the materials will collide with the instrument, causing damage and failure of the instrument. If the damaged and failed instrument is not replaced in time, it will bring unknown safety hazards of overloading and over-limit operation to the construction. If the instrument is replaced multiple times, it will incur a large economic cost

[0005] Risk of sensor data distortion or failure: During the construction of the unloading platform, sensor data may occasionally be distorted or fail, making it difficult to distinguish the authenticity of the over-limit alarm data; during the construction of the unloading platform, personnel may change frequently. When over-limit use or illegal operation occurs, it is difficult to identify the specific illegal operator, which may cause the operator to have a fluke mentality and increase the probability of continuing illegal operations.

[0006] In view of this, it is necessary to propose an integrated unloading platform with overload alarm function to solve the above problems. Utility Model Content

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0039] Reference Figures 1 to 9 As shown, an embodiment of the utility model provides an integrated unloading platform with an overload alarm function, which is composed of a load frame body 10, a loading area load-bearing body 20, and an edge protection body that are combined and connected to form a main structure of the unloading platform. The main structure of the unloading platform is also connected to a sensor and data transmission module, a core control module and an overload alarm module. The sensor and data transmission module and the overload alarm module are all electrically connected to the core control module, wherein the core control module includes a cloud storage unit, an Internet of Things unit, a remote inspection unit and a terminal software unit.

[0040] Specifically, the load-bearing frame body 10 is composed of a steel main beam 2, a steel secondary beam 1, a load-bearing hanger 4, and a transfer ring 5. The steel secondary beam 1 and the steel main beam 2 are welded together to form a steel structure. The load-bearing hanger 4 is welded to the outside of the steel main beam 2, and the transfer ring 5 is welded to the inside of the steel main beam 2. A plurality of steel secondary beams 1 are connected transversely between the parts of the two steel main beams 2 cantilevered outside the main body of the building structure, and the loading area load-bearing body 20 is connected above this part of the load-bearing frame body 10. Two transfer rings 5 ​​are fixed to the inner side of the steel main beam 2 at intervals along its length. A total of four transfer rings 5 ​​for lifting are provided on the two steel main beams 2. The four transfer rings 5 ​​are symmetrically arranged in pairs. Each of the transfer rings 5 ​​is formed by bending steel bars / steel plates with an outer diameter of 20 mm and welded or bolted to the inner side of the steel main beam 2. The load-bearing hanger plate 4 is a 20mm thick hanger plate, which is fixed to the outside of the steel main beam 211 at a certain angle along the direction of the cable. It can be welded or bolted. The two load-bearing hangers 4 are respectively connected to the main inclined cable and the auxiliary inclined cable. One end of the inclined cable is fixedly connected to the load-bearing hanger plate 4 pin, and the other end is connected to the fixed pin embedded in the building. The inclined cable is tensioned and stressed to withstand the gravity from the unloading platform. A stiffening plate 3 is connected between the load-bearing hanger plate 4 and the steel main beam 2. The stiffening plate 3 is a 10mm thick steel plate welded in the notch of the steel main beam 2. Specifically, Figures 2 to 4 shown.

[0041] One end of the steel main beam 2 is located inside the building and is fixed on the building floor. A steel stopper 9 is fixed underneath it, which abuts the edge of the floor. While forming a limit in the longitudinal direction, the steel stopper 9 can be used to connect with the building structure. For example, by passing bolts through the steel stopper 9 and then fastening it to the building floor, it can ensure that the position of the entire unloading platform and the floor will not deviate.

[0042] The load-bearing body 20 of the loading area is composed of a load-bearing panel 21, a load-bearing main purlin 22, and a load-bearing secondary purlin 23. The load-bearing panel 21 is generally made of patterned steel plates. The load-bearing main purlins 22 are arranged in a cross arrangement on the four sides of the load-bearing panel 21 and in the middle longitudinal and transverse directions. A load-bearing secondary purlin 23 is arranged in the gap between the two load-bearing main purlins 22 as a supplementary load-bearing reinforcement measure for the load-bearing panel 21 to avoid deformation of the load-bearing panel 21 due to excessive spacing between the load-bearing main purlins 22. In order to ensure the load-bearing safety of the loading area of ​​the unloading platform, the load-bearing points of the loading area are evenly distributed in a multi-point manner on the steel main beams 2 on both sides and the local steel secondary beam 1 in the middle to avoid the risk of damage and collapse caused by the steel main beam 2 or a single steel secondary beam 1 bearing a large load. Specifically, Figure 5 shown.

[0043] The edge protection body is composed of a protection keel 61, a bottom fixed keel 62, and a side guard plate 63. It is arranged on the left, right, and outer edges of the load-bearing body 20 in the loading area. The inner side of the loading area is used as the entrance for loading materials. The protection keels 61 on the left and right sides near the outer edges are provided with connection holes 64 for fixing the outer protection keels 61 with tie bolts 8, so that the outer protection body and the protection bodies on the left and right sides are connected to form a protective whole. Figure 6 shown.

[0044] At least three weighing sensors 30 are distributed along the longitudinal edges of the load-bearing panel 21, and at least two are distributed along the longitudinal center axis of the load-bearing panel 21. The sensor and data transmission module consists of a weighing sensor 30 and a data transmission junction box. Weighing sensors 30 are installed at the load-bearing points of the load-bearing body 20 in the loading area to ensure that when materials are loaded in any area of ​​the loading area, there are no fewer than three load-bearing points of the weighing sensors 30 bearing the weight, ensuring the authenticity of the weighing data. The front-end fixing bolts of the sensor are inserted through the main keel of the load-bearing area, the load-bearing panel 21, and the fixing keel 62 at the bottom of the edge protection, and then firmly fixed with nuts. The bolt mounting holes at the rear end of the sensor are inserted through fixing bolts and nuts at the main beam openings and secondary beam openings to secure them. To prevent stress loss caused by the main beam openings and secondary beam openings, steel pads are welded to the upper surface of the flange plate at the openings to reinforce them. The corresponding installation locations of the sensors are mostly located at the edge of the unloading platform. According to the bolt diameter, mechanical holes can be drilled and bolts can be installed at the corresponding component locations to facilitate leveling, adjustment, and inspection and tightening of the weighing assembly.

[0045] The sensor is connected to the data transmission junction box. After the junction box receives the data, it is sent to the core control module via wireless data transmission such as Bluetooth, WIFI, LoRa, WLAN, Zigbee, etc.

[0046] The core control module is an industrial computer running the Android operating system. It includes an LCD display, power supply, USB port, IoT transmission antenna, audio and visual alarm interface, wireless data receiving components (such as Bluetooth, Wi-Fi, LoRa, WLAN, and ZigBee), camera, microphone, speaker, CPU processor, and monitoring and control logic software. This module is deployed in the intelligent system control box on the unloading platform. Functions include receiving the load value from the weighing sensor and displaying it in real time on the display. The monitoring and control logic software monitors and displays the load value's over-limit, overload, and real-time status. It also controls the audio and visual alarm module to issue voice announcements and flashing lights based on one or more over-limit items. It also controls the IoT unit to send sensor data, over-limit operation monitoring data, and other information to a cloud storage unit in real time.

[0047] The Internet of Things unit uses a 4G / 5G network transmission module, is installed on an Android system industrial computer, and is controlled by the core control module to realize the transmission of sensor data, over-limit operation monitoring data and other information between the core control module and the cloud storage unit by wireless communication.

[0048] The over-limit alarm module includes an audible and visual alarm light for on-site alarm, and an alarm signal sending end connected to the terminal software unit signal and used to send out off-site alarm signals; the on-site audible and visual alarm light is deployed at the top of the intelligent control box, connected to the core control module through a transmission line, controlled by the core control software, and receives instructions from the core control module to realize voice broadcast alarms and light flashing alarms for over-limit monitoring projects; the alarm signal sending end sends APP software pop-up alarms and SMS notification alarms to the user terminal through the terminal software unit; APP software pop-up alarms and SMS notification alarms are off-site mode alarms, and are used in conjunction with the cloud background and front-end mobile phone software.

[0049] Remote inspection unit The remote inspection unit consists of an Android industrial computer with a camera, speaker, and microphone, a cloud-based image and audio recording function, and an APP software with a video call function between the industrial computer and the computer. When an over-limit alarm message is received, or when performing daily scheduled or irregular inspections, the camera and microphone of a specific industrial computer on site can be turned on from the cloud background to achieve live recording of on-site operation images and audio, or the one-click video call function can be turned on from the mobile phone APP software to turn on the camera, speaker, and microphone of a specific industrial computer to achieve video intercom calls with operators and live inspections of on-site operations. During the video inspection, the mobile phone screen recording function can be turned on to save the inspection images and audio files on the mobile phone.

[0050] The cloud storage unit is the cloud background database, which receives and stores the real-time monitoring data transmitted by the core control module, stores key information such as the client login username and password, receives data request services sent by the client software, and sends real-time monitoring data, over-limit item alarm information, historical monitoring data and other information to the client software.

[0051] The terminal software unit includes client APP, web cloud platform and other forms. It can be logged in through mobile phone or computer. The login username and password need to be entered. If they are consistent with the username and password stored in the cloud, the login is successful. The functions implemented include: querying real-time monitoring data, querying statistics of over-limit project alarm information and / or historical monitoring data, and displaying them in the form of charts.
