Description

Technical Field

[0001] This utility model relates to the field of weighbridges, specifically a prefabricated weighbridge foundation structure. Background Technology

[0002] A weighbridge is a large weighing device installed in the ground. It is mainly used to measure the weight of vehicles or goods and plays an important role in transportation, construction, warehousing and logistics. The foundation structure of the weighbridge is a key component to ensure the stability, accuracy and durability of the weighbridge, ensuring that the foundation has sufficient load-bearing capacity, stability and durability.

[0003] In existing technology, weighbridges can weigh large trucks and other goods to ensure traffic safety during transportation and minimize overloading. Typically, the base of a weighbridge is connected by a steel frame. To reduce the complexity of weighbridge installation, the steel frame is usually connected using bolts and other tools in an assembly manner. However, when using bolts to connect the steel frames, the bolts are prone to rusting over time, which reduces the stability of the steel frames. Furthermore, bolted connections require frequent tightening of the bolts by workers. When workers connect or disassemble the steel frame for maintenance, the operation is still relatively troublesome and cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, bolts used to connect steel frames are prone to rusting over time, which reduces the stability of the steel frames. Furthermore, bolted connections require frequent tightening of the bolts, making the connection or disassembly of the steel frames cumbersome and inconvenient. This invention proposes a prefabricated weighbridge foundation structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a prefabricated weighbridge foundation structure, including a weighbridge body, a fixed steel frame fixedly connected to the bottom of the weighbridge body, a U-shaped steel frame provided at the bottom of the fixed steel frame, a connecting block fixedly connected to the inner cavity of the U-shaped steel frame, and a connecting mechanism provided in the inner cavity of the connecting block.

[0006] The connecting mechanism includes a slide rod, the surface of which is slidably connected to the inner cavity of the connecting block. A hollow sleeve is fixedly connected to the top of the slide rod. A connecting plate and a fixing ring block are fixedly connected to the surface of the hollow sleeve. A rotating rod is rotatably connected to the inner cavity of the connecting plate. A pressure block is rotatably connected to the surface of the rotating rod. A limit rod is fixedly connected to the inner cavity of the connecting block. The surface of the limit rod is slidably connected to the inner cavity of the pressure block. A return spring is fixedly connected to the inner cavity of the connecting block. One end of the return spring is fixedly connected to the bottom of the fixing ring block. A pressing assembly is provided in the inner cavity of the slide rod. A driving assembly is provided at the bottom of the pressing assembly.

[0007] Preferably, the pressing assembly includes a movable plate, the surface of which is slidably connected to the inner cavity of the connecting block, the inner cavity of the slide rod is provided with a hollow inclined groove, the surface of the movable plate is slidably connected to the inner cavity of the hollow inclined groove, and a wedge block is fixedly connected to the bottom of the movable plate.

[0008] Preferably, the drive assembly includes a moving block, the top of which is fixedly connected to the bottom of the moving plate, a servo motor is fixedly connected to the inner cavity of the U-shaped steel frame, a screw is fixedly connected to the output end of the servo motor, and the surface of the screw is threadedly connected to the inner cavity of the moving block.

[0009] Preferably, a limiting rod is fixedly connected to the top of the slide rod, and a limiting plate is fixedly connected to the inner cavity of the connecting block, with the inner cavity of the limiting plate slidably connected to the surface of the limiting rod.

[0010] Preferably, the inner cavity of the connecting block is provided with a limiting groove, and the surface of the hollow sleeve is fixedly connected to a limiting plate, the surface of the limiting plate being slidably connected to the inner cavity of the limiting groove.

[0011] Preferably, a fixing rod is fixedly connected to the inner cavity of the connecting block, and the surface of the fixing rod is slidably connected to the inner cavity of the limiting plate.

[0012] Preferably, a reinforcing block is fixedly connected to the inner cavity of the connecting block, and a rubber layer is movably bonded to one side of the pressure block.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a servo motor to smoothly drive the screw to rotate, thereby moving the wedge block and the moving plate. The wedge block compresses the sliding rod, causing it to move downwards. The downward movement of the sliding rod smoothly pulls the pressure block, allowing it to move downwards and rotate at a certain angle, thus clamping and connecting the fixed steel frame. This makes connecting and disassembling the U-shaped steel frame and the fixed steel frame convenient and easy when workers need to connect them and ensure the normal use of the weighbridge. This increases the convenience of installing and using the weighbridge and reduces the likelihood of shaking and instability in the connection between the U-shaped steel frame and the fixed steel frame due to rust. It also solves the problems of bolts, which are prone to rusting after prolonged use, reducing the stability of the steel frames. Furthermore, bolted connections require frequent tightening of the bolts, making the connection or disassembly of the steel frames cumbersome and complicated. Attached Figure Description

[0025] 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 scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0027] This application discloses a prefabricated weighbridge foundation structure. (Refer to...) Figure 1 and Figure 8 A prefabricated weighbridge foundation structure includes a weighbridge body 1, a fixed steel frame 3 fixedly connected to the bottom of the weighbridge body 1, a U-shaped steel frame 2 provided at the bottom of the fixed steel frame 3, a connecting block 4 fixedly connected to the inner cavity of the U-shaped steel frame 2, and a connecting mechanism 5 provided in the inner cavity of the connecting block 4.

[0028] The connecting mechanism 5 includes a slide rod 501, the surface of which is slidably connected to the inner cavity of the connecting block 4. A hollow sleeve 502 is fixedly connected to the top of the slide rod 501. A connecting plate 503 and a fixing ring block 507 are fixedly connected to the surface of the hollow sleeve 502. A rotating rod 504 is rotatably connected to the inner cavity of the connecting plate 503. A pressure block 505 is rotatably connected to the surface of the rotating rod 504. A limiting rod 506 is fixedly connected to the inner cavity of the connecting block 4. The surface of the limiting rod 506 is slidably connected to the inner cavity of the pressure block 505. A return spring 508 is fixedly connected to the inner cavity of the connecting block 4. One end of the return spring 508 is fixedly connected to the bottom of the fixing ring block 507. A pressing component 509 is provided in the inner cavity of the slide rod 501. A driving component 510 is provided at the bottom of the pressing component 509.

[0029] The weighbridge body 1 can effectively monitor the weight of large objects such as goods and trucks. Generally, the weighbridge body 1 is composed of electronic weighing devices, electronic sensors and other equipment. The weighbridge body 1 is existing technology in this field, so it will not be elaborated on here. The U-shaped steel frame 2 and the fixed steel frame 3 can support and install the weighbridge body 1. At the same time, the connecting block 4 inside the U-shaped steel frame 2 can facilitate the mutual installation of the U-shaped steel frame 2 and the fixed steel frame 3.

[0030] Furthermore, the connecting block 4 can be connected to the hollow sleeve 502 via the sliding rod 501, and the hollow sleeve 502 can be used to install the pressure block 505 via the connecting plate 503 and the rotating rod 504. The limiting rod 506 can limit the pressure block 505, and the connecting block 4 can also cooperate with the fixing ring block 507 installed on the surface of the hollow sleeve 502 to install and fix the return spring 508. At the same time, when the pressing component 509 is in use, it can drive the sliding rod 501 to move up and down. When the sliding rod 501 moves up, it can drive the pressure block 505 to move up together via the rotating rod 504, and rotate on the surface of the limiting rod 506 and rotate at a certain angle, thereby achieving clamping and connection of the fixed steel frame 3. When the sliding rod 501 moves down, it can drive the pressure block 505 to release the clamping and connection of the fixed steel frame 3.

[0031] Reference Figure 7 and Figure 8 The pressing component 509 includes a movable plate 5092, the surface of which is slidably connected to the inner cavity of the connecting block 4. The inner cavity of the slide rod 501 is provided with a hollow inclined groove 5091. The surface of the movable plate 5092 is slidably connected to the inner cavity of the hollow inclined groove 5091. A wedge block 5093 is fixedly connected to the bottom of the movable plate 5092. The connecting block 4 can be connected to the wedge block 5093 through the movable plate 5092. When the wedge block 5093 moves, it can push the slide rod 501 through the hollow inclined groove 5091, causing it to move downward. When the movable plate 5092 and the wedge block 5093 move in opposite directions, the pressure on the slide rod 501 can be released, allowing it to move upward and reset by the elasticity of the return spring 508.

[0032] Reference Figure 4 and Figure 7The drive assembly 510 includes a moving block 5101, the top of which is fixedly connected to the bottom of a moving plate 5092. A servo motor 5103 is fixedly connected to the inner cavity of the U-shaped steel frame 2. A screw 5102 is fixedly connected to the output end of the servo motor 5103. The surface of the screw 5102 is threadedly connected to the inner cavity of the moving block 5101. When the servo motor 5103 is operating, it can smoothly drive the screw 5102 to rotate and smoothly drive the moving plate 5092 to move through the threaded connection between the screw 5102 and the moving block 5101, thereby realizing the use of the pressure block 505.

[0033] Reference Figure 6 and Figure 7 A limiting rod 7 is fixedly connected to the top of the slide rod 501, and a limiting plate 6 is fixedly connected to the inner cavity of the connecting block 4. The inner cavity of the limiting plate 6 is slidably connected to the surface of the limiting rod 7. The setting of the limiting plate 6 and the limiting rod 7 makes the slide rod 501 subject to the limiting plate 6 when it moves up and down, so that the slide rod 501 can be sufficiently stable when it moves up and down.

[0034] Reference Figure 4 and Figure 7 The inner cavity of the connecting block 4 is provided with a limiting groove 9, and the surface of the hollow sleeve 502 is fixedly connected to a limiting plate 8. The surface of the limiting plate 8 is slidably connected to the inner cavity of the limiting groove 9. The sliding connection between the limiting plate 8 and the limiting groove 9 can effectively further restrict the up and down movement of the slide rod 501 through the fixed ring block 507, thereby increasing the stability of the connecting mechanism 5 during use.

[0035] Reference Figure 7 and Figure 8 A fixing rod 10 is fixedly connected to the inner cavity of the connecting block 4. The surface of the fixing rod 10 is slidably connected to the inner cavity of the limiting plate 8. The fixing rod 10 can restrict the limiting plate 8, so that when the limiting plate 8 plays a limiting role in the movement of the fixing ring block 507 through the limiting groove 9, the limiting plate 8 itself has high stability and stability.

[0036] Reference Figure 4 and Figure 6 A reinforcing block 11 is fixedly connected to the inner cavity of the connecting block 4, and a rubber layer 12 is movably bonded to one side of the pressure block 505. The reinforcing block 11 can strengthen the use of the connecting block 4, while the rubber layer 12 can increase the friction between the pressure block 505 and the fixed steel frame 3, thereby improving the stability of the fixed steel frame 3 when it is connected to the U-shaped steel frame 2.

[0037] Working Principle: When using this device, the operator can place the fixed steel frame 3 on top of the U-shaped steel frame 2, and then start the servo motor 5103. During operation, the servo motor 5103 smoothly drives the screw 5102 to rotate. Utilizing the threaded connection between the screw 5102 and the moving block 5101, it smoothly drives the moving plate 5092 and the wedge block 5093 to move. During this movement, the wedge block 5093 smoothly pushes the sliding rod 501 downwards. As the sliding rod 501 moves downwards, it pulls the pressure block through the connecting plate 503 and the rotating rod 504. 505 allows the pressure block 505 to rotate during its downward movement through its connection with the rotating rod 504 and the limiting rod 506, thereby clamping the fixed steel frame 3 and connecting the fixed steel frame 3 with the U-shaped steel frame 2. When it is necessary to disassemble the connection between the U-shaped steel frame 2 and the fixed steel frame 3, simply reverse the start of the servo motor 5103, causing the servo motor 5103 to drive the wedge block 5093 to move in the opposite direction. The return spring 508 can then elastically drive the pressure block 505 to reset, releasing the connection and clamping of the fixed steel frame 3, facilitating subsequent maintenance and disassembly.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
