This utility model discloses an axle-weight truck scale, relating to the field of weighing equipment technology. The utility model includes several scale bodies, each with several mounting grooves on its inner wall. A crossbeam is slidably connected to the inner wall of each mounting groove. By incorporating an indicator plate, the utility model allows a motor to drive a worm gear, which in turn drives a pulley and a worm wheel to rotate. The worm wheel then drives a threaded rod to move upwards, which in turn drives a slide rail to move upwards. The slide rail then drives a sliding rod to slide, which in turn causes the indicator plate to flip. During this process, the pulley drives a belt to rotate, which in turn drives a pulley to rotate. The pulley then drives the threaded rod to rotate, which in turn causes several displacement shafts to move away from each other. Each displacement shaft then drives a rotating shaft to move, and a telescopic rod drives the displacement of the shaft. This allows the utility model to provide positional information to the driver inside the vehicle when weighing is required.

Description

Technical Field

[0001] This utility model belongs to the technical field of weighing equipment, and in particular relates to an axle load type truck scale. Background Technology

[0002] According to the published patent CN214667191U, an axle-load truck scale includes multiple body sections and multiple crossbeams. The crossbeams are detachably connected to the two short sides of the body sections. Since only the tires on both sides of the vehicle are in contact with the scale when it runs on the axle-load truck scale, the space in the middle is freed up, which not only saves materials and reduces costs, but also reduces the overall weight of the truck scale. Furthermore, the crossbeams of this axle-load truck scale are detachably connected to the body sections, which facilitates transportation and reduces transportation costs. However, it still has the following shortcomings. The above-mentioned equipment can only be used to disassemble and separate the crossbeam from the main body for transportation, but the effect is relatively simple. When it is necessary to weigh a car, it is not very convenient for the driver inside the car to observe whether the weighing position is appropriate. As a result, the accuracy of the weighing data may be affected due to the car not being weighed properly, and the reliability of the equipment is poor. Therefore, we propose an axle load type truck scale. Utility Model Content

[0003] The purpose of this utility model is to provide an axle load type truck scale. Through the indicating mechanism and quick-release mechanism, it solves the problems of the limited functionality of only being able to separate the crossbeam from the main body for transportation, which is not conducive to the driver in the vehicle observing whether the weighing position is appropriate when weighing the vehicle. As a result, the accuracy of the weighing data may be affected due to the vehicle not being weighed properly, and the reliability of the equipment is poor.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an axle load type truck scale, including several scale bodies, each scale body having several mounting grooves on its inner wall, each mounting groove having a crossbeam slidably connected to its inner wall, each crossbeam having several pressure sensors fixedly connected to its inner wall, and each crossbeam having an indicating mechanism. The indicating mechanism includes a motor, the outer wall of which is fixedly connected to the inner wall of the crossbeam. A worm gear is fixedly connected to the bottom output shaft of the motor via a coupling. A pulley is fixedly connected to the outer wall of the worm gear at the end furthest from the motor. The outer wall of the pulley is rotatably connected to the inner wall of the crossbeam. A belt is driven through the outer wall of the pulley, and a second pulley is driven through the inner wall of the belt. The outer wall of the second pulley is rotatably connected to the inner wall of the crossbeam. A threaded rod is fixedly connected to the outer wall of the second pulley, and the outer wall of the threaded rod is rotatably connected to the inner wall of the crossbeam. Several displacement shaft seats are threadedly connected to the outer wall of the threaded rod, and several sliding rods are slidably connected to the inner wall of each displacement shaft seat. The outer wall is fixedly connected to the inner wall of the crossbeam. The inner wall of the displacement shaft seat is rotatably connected to a rotating shaft. The outer wall of the rotating shaft is fixedly connected to a telescopic rod. The top outer wall of the telescopic rod is fixedly connected to a second rotating shaft. The outer wall of the second rotating shaft is rotatably connected to a second shaft seat. The outer wall of the second shaft seat is fixedly connected to an extension indicator plate. The inner wall of the crossbeam is fixedly connected to a worm gear frame. The top outer wall of the worm gear frame is rotatably connected to a worm gear. The outer wall of the worm gear meshes with the outer wall of the worm. The inner wall of the worm gear is threadedly connected to a second threaded rod. The top outer wall of the second threaded rod is fixedly connected to a slide rail. The inner wall of the crossbeam is rotatably connected to an indicator plate. The inner wall of the indicator plate has a sliding groove. The inner wall of the indicator plate is fixedly connected to a sliding rod.

[0005] Furthermore, the inner wall of the chute is slidably connected to the outer wall of a plurality of extended indicator plates, and the outer wall of the sliding rod is slidably connected to the inner wall of the slide rail.

[0006] Furthermore, the inner wall of the crossbeam is provided with a quick-release mechanism, which includes several limiting rods, the outer walls of which are fixedly connected to the inner wall of the crossbeam.

[0007] Furthermore, a connecting plate is slidably connected to the outer wall of several of the limiting rods, and several springs are fixedly connected to the bottom outer wall of the connecting plate.

[0008] Furthermore, the bottom outer walls of several springs are fixedly connected to the interior of the crossbeam, and the top outer wall of the connecting plate is fixedly connected with several fixing pins.

[0009] Furthermore, the inner wall of the connecting plate is provided with a fastening groove, and the interior of the crossbeam is provided with an installation groove.

[0010] Furthermore, a sealing plate is slidably connected to the inner wall of the second mounting groove, and a handle is fixedly connected to the inner wall of the sealing plate.

[0011] Furthermore, the inner wall of the sealing plate is provided with a plurality of fixing grooves, and the outer walls of the plurality of fixing grooves are slidably connected to the outer wall of the fixing pin.

[0012] This utility model has the following beneficial effects: 1. This utility model, by setting an indicator plate, allows the motor to drive the worm gear to rotate, which in turn drives the pulley and worm wheel to rotate. The worm wheel then drives the threaded rod to move upward, which in turn drives the slide rail to move upward. The slide rail then drives the sliding rod to slide, which in turn causes the indicator plate to flip. During this process, the pulley drives the belt to rotate, which in turn drives the pulley to rotate. The pulley then drives the threaded rod to rotate, which in turn drives several displacement shafts to move away from each other. Each displacement shaft then drives the rotating shaft to move, which in turn drives the telescopic rod to move. The telescopic rod then drives the shaft seat to move. This achieves the goal of providing a positional indication to the driver when a vehicle needs to be weighed, thus avoiding potential issues with the accuracy of the weighing data due to the vehicle's inaccurate weighing position.

[0013] 2. This utility model, by setting fixed pins, allows the connecting plate to be pulled down using the latch groove. The connecting plate will cause several fixed pins to descend and disengage from the fixed groove, thus no longer restricting the sliding of the sealing plate. Then, pulling the handle outward will cause the sealing plate to move and disengage from the second mounting groove. After separating several sealing plates, the crossbeam can be pushed out of the mounting groove to complete the individual separation of the scale body. When assembling and installing, simply reverse the above steps. During this process, the connecting plate will be held in place by several fixed pins inserted into the fixed groove under the action of several springs to restrict the displacement of the sealing plate. This allows for rapid disassembly and separation of the entire equipment, greatly reducing the space occupied and the burden during transportation. The operation is simple and efficient.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
