Description

Technical Field

[0001] The utility model belongs to the technical field related to truck scales, and particularly relates to a truck scale limit component. Background Technique

[0002] A truck scale is a weighing instrument used to weigh trucks. Existing truck scales usually include a foundation pit and a weighing platform plate arranged on the ground. A weighing sensor is arranged between the bottom of the weighing platform plate and the foundation pit, and the weighing sensor is connected to a computer system. When weighing a truck, the truck first drives to the middle position of the weighing platform plate. The weighing sensor can sense the weight of the truck and convert it into a corresponding electrical signal and transmit it to the computer system. After calculation by the computer system, the weight of the truck can be displayed. When the truck scale is working, in order to determine that the truck is in a specified position on the truck scale during work, a limit component needs to be used to determine the position of the truck. However, it still has the following drawbacks in actual use:

[0003] When the truck scale limit component is working, after the truck directly drives to a suitable position, during the work of the truck, the driver needs to make a judgment by himself. When working, manual operation requires relatively high skills and the work efficiency is not high.

[0004] When the truck scale limit component is working, it will limit the position of the truck. During the process of restricting the truck, the truck moves on the truck scale. When moving on the truck scale, the truck drives directly. During the driving process, it is easy for the truck to touch the limit component, affecting the integrity of the truck. Content of the Utility Model

[0005] The purpose of the utility model is to provide a truck scale limit component, which solves the problems of inconvenient limiting when the truck scale limit component is working and the truck is easily touched by the limit component when the truck is driving by setting a fixing plate, a supporting plate, a back plate and a fitting plate.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a limit component for a weighbridge, which comprises a fixing plate, a supporting plate, a back plate and a fitting plate. One side of the longitudinal center line of the fixing plate is connected with the back plate in a penetrating and movable manner. A fitting plate is fixed at the top end of the back plate. A connecting block is fixed in the middle of the bottom of the fitting plate, close to one side of the longitudinal center line of the top of the fixing plate. A bulb is fixed on one side of the connecting block, close to the longitudinal center line of the top of the fixing plate. A supporting plate is fixed at the bottom of the back plate. During operation, the fixing plate is connected to the top of the weighbridge, the back plate and the fitting plate are supported on the fixing plate through the supporting plate. When the back plate is working, a push switch for supplying power to the bulb is connected to a structure driven by a hydraulic cylinder thereon, and the fitting plate provides a driving support for the vehicle after weighing.

[0008] Further, an activity opening is penetrated and formed inside the fixing plate on the outer side of the back plate. The back plate is movably connected to one side of the activity opening, far from the longitudinal center line of the fixing plate. A limiting opening is formed on the outer side of the activity opening at the top of the fixing plate. The limiting opening is the same size as the fitting plate, and the depth of the fitting opening is the same as the thickness of the fitting plate. A notch is formed on one side of the activity opening, far from the center line of the top of the fixing plate. The fixing plate is movably connected to the back plate through the activity opening and movably connected to the fitting plate through the limiting opening.

[0009] Further, electric push rods are symmetrically fixed at the bottom of the supporting plate along the transverse center line. The supporting plate is arranged below the fixing plate. When the supporting plate is working, its lifting is driven by the electric push rods.

[0010] Further, hydraulic cylinders are symmetrically fixed at the middle part of one side of the back plate, far from the center line of the top of the fixing plate, along the center line in the vertical direction. A hydraulic rod is movably connected inside each hydraulic cylinder. The hydraulic rod is movably connected through the back plate. When the back plate is working, the movement of the hydraulic rod is driven by the hydraulic cylinder to drive the movement of the push plate.

[0011] Further, a push plate is jointly fixed at one ends of the two hydraulic rods, far from the back plate. A push switch is fixed at the center of one side of the push plate, far from the back plate. When the hydraulic rod is working, the push plate is driven, so that the push plate is pushed to press the push switch.

[0012] Further, movable rods are movably connected through the push plate between the two hydraulic rods and the push switch. Compression springs are fixed on the outer side of the movable rods, on the side of the push plate, far from the back plate. A contact plate is jointly fixed at one ends of the two compression springs and the two movable rods, far from the back plate. A pressing block is fixed at the center of one side of the contact plate, close to the push plate. The pressing block is in contact with the push switch. A protective sponge block is fixed on the side of the contact plate, far from the back plate. When the hydraulic rod is working, the compression spring is driven by the movable rod, so that when working, the push switch is pressed by the pressing block.

[0013] The utility model has the following beneficial effects:

[0014] By arranging a fixing plate, a supporting plate, a back plate and a fitting plate, the utility model solves the problem of inconvenient limiting when the vehicle scale limiting component works. Start the electric push rod, the electric push rod drives the supporting plate, and drives the back plate to rise above the fixing plate. Then start the hydraulic cylinder to drive the hydraulic rod to move, so that the hydraulic rod drives the pushing plate to move above the fixing plate. When working, the vehicle can drive onto the fixing plate. When the vehicle is driving, it contacts the protection sponge block, pushes the contact plate, so that the pressing block on the contact plate presses down the pressing switch, and at this time the bulb lights up. After the bulb lights up, it is determined that the vehicle is in place on the fixing plate, making the vehicle scale limiting component more convenient to limit when working.

[0015] By arranging a fixing plate, a supporting plate, a back plate and a fitting plate, the utility model solves the problem that the vehicle is likely to touch the limiting component when driving. Immediately start the electric push rod after weighing, drive the supporting plate and the back plate to descend, so that the supporting plate descends and drives the back plate to descend. After the back plate descends to the fitting plate enters the limiting port on the fixing plate, the vehicle can drive on the fixing plate and move to the next working position through the fitting plate. After weighing, when the vehicle is driving, it is less likely to touch the limiting component, ensuring driving safety. Description of the Drawings
