Description

Technical Field

[0001] This utility model relates to the field of counting device technology, specifically a counting device for monitoring the entry and exit of materials at a construction site. Background Technology

[0002] With the booming development of the construction industry, the scale of construction sites is expanding day by day, and the complexity of material management is increasing day by day. This has led to the emergence of construction site material entry and exit monitoring and counting devices.

[0003] With the advancement of technology, computer technology has begun to play a preliminary role. Some construction sites are trying to use simple database software to input material entry and exit information into computers, which improves the convenience of data storage and retrieval.

[0004] To ensure real-time capture of the entry and exit of materials and vehicles, the high-definition cameras in the device are usually in a completely exposed state when not being inspected, without any effective shielding devices. Construction sites are inherently dusty environments, and various construction activities, such as earthwork excavation, sand and gravel loading and unloading, and building material cutting and grinding, will generate a large amount of dust particles that permeate the air. Cameras that are exposed to the outside for a long time will inevitably be obscured by dust. Utility Model Content

[0005] The purpose of this invention is to provide a monitoring and counting device for the entry and exit of materials at construction sites, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction site material entry and exit monitoring and counting device, comprising:

[0007] The weighbridge has a sliding plate slidably connected to it.

[0008] A transmission assembly is placed inside the weighbridge. The transmission assembly includes a connecting rod slidably connected inside the weighbridge, a sliding block fixedly connected to the connecting rod, a pressing rod fixedly connected to the sliding block, a sliding shaft fixedly connected to the pressing rod, a transmission block slidably connected to the sliding shaft, a connecting shaft fixedly connected to the transmission block, a baffle plate fixedly connected to the connecting shaft, and an oblique hole provided on the transmission block. The sliding shaft is slidably connected to the oblique hole on the transmission block.

[0009] A bracket is fixedly connected to the weighbridge, and a first mounting frame is fixedly connected to the bracket on the weighbridge. The baffle is slidably connected to the first mounting frame.

[0010] A transmission bar is rotatably connected inside the first mounting frame, and a second mounting frame is slidably connected to the transmission bar. The second mounting frame is rotatably connected inside the first mounting frame.

[0011] Furthermore, the transmission bar is rotatably connected to the first mounting frame via a rotating shaft, and the second mounting frame is rotatably connected to the first mounting frame via a rotating shaft.

[0012] The above technical solution is adopted: by setting a transmission bar, when the transmission bar is moved during use, it can drive the transmission bar to rotate, so that the transmission bar moves the second mounting frame to rotate.

[0013] Furthermore, a damping mechanism is fixedly connected between the weighbridge and the sliding plate.

[0014] The above technical solution involves a damper fixedly connected between the weighbridge and the sliding plate, making it convenient to reset the sliding plate during use.

[0015] Furthermore, the weighbridge has an opening, and the sliding block is slidably connected to the opening on the weighbridge.

[0016] The above technical solution is adopted: by opening a hole in the base plate, the sliding block on the weighbridge plays a limiting role in the downward pressure rod.

[0017] Furthermore, a partition is fixedly connected to the first mounting frame, and an opening is provided on the partition inside the first mounting frame. The transmission bar is slidably connected to the opening in the partition inside the first mounting frame.

[0018] The above technical solution is adopted: by fixing a partition to the first mounting frame, it is convenient to block one side of the first mounting frame during use.

[0019] Furthermore, a limit frame is fixedly connected to the bracket on the weighbridge, and the transmission block is slidably connected within the limit frame.

[0020] The above technical solution is adopted: by setting a limit frame, it is convenient to limit the sliding of the transmission block during use.

[0021] Furthermore, a cylindrical block is fixedly connected to the shielding plate.

[0022] The above technical solution is adopted: by setting up a cylindrical block, the transmission bar is pressed and moved by the cylindrical block on the baffle plate during the sliding process.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] 1. In this utility model, when a vehicle enters, it presses down on the sliding plate of the weighbridge. After the sliding plate is subjected to force, it pushes down the connecting rod. The connecting rod drives the sliding block and the pressing rod fixed to it to slide downward. The sliding shaft on the pressing rod slides in the inclined hole of the transmission block. Due to the guiding effect of the inclined hole, the transmission block is pushed to slide, and then drives the shielding plate to slide through the connecting shaft. In the non-working state, the shielding plate can effectively shield the camera, isolate it from the dusty environment of the construction site, and prevent the invasion of dust particles. When a vehicle is triggered, the camera is quickly exposed to capture the material and vehicle entry and exit images in real time, which solves the problem of the camera being exposed to the outside for a long time in the prior art.

[0025] 2. In this utility model, the moment the cover slides open, the cylindrical block fixed on it actuates the transmission bar to rotate. The transmission bar rotates within the first mounting frame via a rotating shaft, thereby causing the second mounting frame, which is slidably connected to the cover and rotated within the first mounting frame via the rotating shaft, to tilt up, disengage from its retracted state, and align with the vehicle. The light fixed within the second mounting frame then immediately illuminates the vehicle with strong light. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example:

[0037] like Figures 1-4 As shown, this utility model provides a technical solution: a construction site material entry and exit monitoring and counting device, comprising:

[0038] Weighbridge 1, with a sliding plate 11 slidably connected to it;

[0039] Transmission component 2 is placed inside the weighbridge 1. Transmission component 2 includes a connecting rod 21 that is slidably connected inside the weighbridge 1. A sliding block 26 is fixedly connected to the connecting rod 21. A pressing rod 22 is fixedly connected to the sliding block 26. A sliding shaft 24 is fixedly connected to the pressing rod 22. A transmission block 23 is slidably connected to the sliding shaft 24. A connecting shaft 3 is fixedly connected to the transmission block 23. A baffle plate 27 is fixedly connected to the connecting shaft 3. An oblique hole is opened on the transmission block 23. The sliding shaft 24 is slidably connected in the oblique hole on the transmission block 23.

[0040] A bracket is fixedly connected to the weighbridge 1, and a first mounting frame 25 is fixedly connected to the bracket on the weighbridge 1. The baffle 27 is slidably connected to the first mounting frame 25.

[0041] A transmission bar 31 is rotatably connected inside the first mounting frame 25, and a second mounting frame 32 is slidably connected to the transmission bar 31. The second mounting frame 32 is rotatably connected inside the first mounting frame 25.

[0042] In this invention, when a vehicle enters, it presses down on the sliding plate 11 on the weighbridge 1. After the sliding plate 11 is subjected to force, it pushes down the connecting rod 21. The connecting rod 21 drives the sliding block 26 and the pressing rod 22 fixed thereto to slide downwards. The sliding shaft 24 on the pressing rod 22 slides in the inclined hole of the transmission block 23. Due to the guiding effect of the inclined hole, the transmission block 23 is pushed to slide, which in turn drives the shielding plate 27 to slide through the connecting shaft 3. In the non-working state, the shielding plate 27 can effectively shield the camera, isolating it from the dusty environment of the construction site and preventing the invasion of dust particles. When a vehicle is triggered, the camera is quickly exposed to capture the material and vehicle entry and exit images in real time, solving the problem of the long-term exposure of the camera in the prior art.

[0043] Furthermore, such as Figures 1 to 4As shown, the transmission bar 31 is rotatably connected to the first mounting frame 25 via a rotating shaft, and the second mounting frame 32 is rotatably connected to the first mounting frame 25 via a rotating shaft. With the transmission bar 31 provided, when the transmission bar 31 is moved during use, it can drive the transmission bar 31 to rotate, so that the transmission bar 31 moves the second mounting frame 32 to rotate.

[0044] A damper is fixedly connected between the weighbridge 1 and the sliding plate 11. By fixing the damper between the weighbridge 1 and the sliding plate 11, it is convenient to reset the sliding plate 11 during use.

[0045] The weighbridge 1 has an opening, and the sliding block 26 is slidably connected in the opening on the weighbridge 1. By having an opening in the base plate, the sliding block 26 on the weighbridge 1 plays a limiting role in the downward pressure rod 22.

[0046] A partition is fixedly connected to the first mounting frame 25. An opening is provided on the partition inside the first mounting frame 25. The transmission bar 31 is slidably connected to the opening in the partition inside the first mounting frame 25. By fixing the partition to the first mounting frame 25, it is convenient to block one side of the first mounting frame 25 during use.

[0047] A limit frame 4 is fixedly connected to the bracket on the weighbridge 1, and the transmission block 23 is slidably connected within the limit frame 4. By setting the limit frame 4, it is convenient to limit the sliding of the transmission block 23 during use.

[0048] The above solution also fails to address the issue of how to drive the transmission bar 31, such as... Figures 1 to 4 As shown, a cylindrical block is fixedly connected to the baffle plate 27. By setting the cylindrical block, the transmission bar 31 is pressed and moved by the cylindrical block on the baffle plate 27 during the sliding process.

[0049] Working principle: such as Figures 1-4 As shown,

[0050] Before use, a lighting lamp is fixed in the second mounting frame 32, and a PLC control board and camera components are installed in the first mounting frame 25. A sensor is installed on the weighbridge 1. When in use, when the vehicle presses down on the sliding plate 11, the sliding plate 11 pushes the connecting rod 21 down. The connecting rod 21 drives the sliding block 26 and the pressing rod 22 to slide down, so that the sliding shaft 24 on the transmission block 23 slides in the inclined groove on the transmission block 23. The transmission block 23 is pushed to slide, causing the transmission block 23 to drive the shield 27 to slide through the connecting shaft 3, so that the camera inside is exposed.

[0051] During this process, the transmission bar 31 is rotated by the cylindrical block on the baffle plate 27, which causes the second mounting frame 32 to be moved, and the end of the frame that mounts the lighting lamp is lifted up, instantly illuminating the vehicle.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
