Description

Technical Field

[0001] The present invention relates to the technical field of intelligent floor scales, and in particular to an intelligent weighing integrated device without a weighing room. Background Art

[0002] In the weighing system of truck scales, traditional weighing information mainly relies on manual entry by the meter operator, which is prone to human error data, and the weighing process is cumbersome and inefficient. In order to meet the development needs of reducing costs and increasing efficiency, unmanned weighing systems have emerged. Unmanned weighing systems do not require an additional weighing room. Instead, a control cabinet is set up on one side of the scale to monitor the weighing process and count the weighing results. Although unmanned weighing rooms do not require human supervision and can save costs, they cannot leave enough space for truck drivers to adjust the position of the vehicle body in limited space. In this way, when truck drivers are on the scale, if there is no guidance from others, it is easy for them to drop the weight or fail to be fully on the scale.

DETAILED DESCRIPTION

[0037] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0038] Example 1: Reference Figure 1-Figure 7 The present invention proposes an intelligent weighing integrated equipment without a weighing room, including a weighing box 1, an upper weighing platform 2 and a lower weighing platform 3 arranged at both ends of the weighing box 1, the weighing platform 2 and the lower weighing platform 3 can be connected to the middle weighing box 1 by bolts, and a support frame 4 is installed under the weighing box 1, and the support frame 4 is fixed with a weighing sensor matched with the weighing box 1. An intelligent control cabinet 5 for controlling the electrical components in the equipment is also arranged on one side of the weighing box 1, and the intelligent control cabinet 5 contains a controller and a battery. The equipment also includes a camera module for identifying the vehicle license plate number and a voice lifting module for voice broadcasting the weighing weight, and can also voice remind the vehicle to get on and off, which can be controlled by the intelligent control cabinet.

[0039] In order to make it safer and more accurate to use, two sets of symmetrically arranged anti-drop scale components are arranged at one end of the sub-scale box 1 close to the upper scale platform 2;

[0040] A gate mechanism is provided at one end of the weighing box 1 close to the lower weighing platform 3, which is used to detect whether the vehicle is fully on the list and can be released after weighing; when it is detected that the value of the distance between the front of the vehicle and the gate mechanism is at the set value, it can be determined that the vehicle is fully on the scale, and after the vehicle is weighed, the intelligent control cabinet 5 can control the gate mechanism to release it.

[0041] Receiving grooves (not marked) for accommodating the anti-dropping assembly are respectively provided on the opposite sides of the weighing box 1. The anti-dropping assembly includes a movable box 6 slidably connected to the receiving groove, and a driving member 59 arranged in the receiving groove for driving the movable box 6 to slide, and the movable box 6 slides along the width direction of the weighing box 1. The top of the movable box 6 is open, and a mounting shaft 37 is connected to the movable box 6. The mounting shaft 37 is rotatably connected to the limiting plate 35. A linkage mechanism is also arranged in the movable box 6. The linkage mechanism is used to drive the limiting plate 35 to rotate, and when the movable box 6 slides out of the receiving groove to a certain position, the movable end of the limiting plate 35 is tilted upward to prevent the wheel from continuing to move forward. When the movable box 6 slides into the receiving groove, the linkage mechanism drives the limiting plate 35 to reset.

[0042] In this solution, the anti-dropping scale assembly also includes an expansion platform 7 movably arranged in the upper scale platform 2. The expansion platform 7 is connected to the movable box 6 and can move synchronously, so that when the movable box is extended, the expansion platform is driven to extend to provide more adjustment space for the upper scale.

[0043] Reference Figure 6 and Figure 7 In this solution, the linkage mechanism includes a push-pull rod 45 connected to the driving member 59, a movable sleeve 44 movably mounted on the outside of the push-pull rod 45, a rack 1 fixed on the outside of the movable sleeve 44, and a transmission unit installed in the movable box 6, and the transmission unit contains a gear 43 meshing with the rack 1, and the power output end of the transmission unit is used to drive the installation shaft 37 to rotate. In this solution, the driving member 59 can be an electric push rod or a hydraulic rod.

[0044] Reference Figure 6 The transmission unit includes a vertical shaft 42 rotatably installed in the movable box 6, a gear three 41 sleeved on the vertical shaft 42, and a gear four 43 also sleeved on the vertical shaft 42. The transmission unit also includes a cross bar 40 slidably connected to the movable box 6, a rack two fixed to the cross bar 40 along the length direction, a gear one 38 sleeved on the outside of the installation shaft 37, and a gear two 39 rotatably arranged in the movable box 6 and meshing with the gear one 38. The gear two 39 and the gear three 41 mesh with the rack two. The rack two is provided with two, and the two mesh with the gear two 39 and the gear three 41 respectively.

[0045] It should be noted that a mounting hole 60 is provided in the movable sleeve 44, and a buffer groove 54 with a larger aperture at one end is provided on the inner wall of the mounting hole 60. A positioning ring 56 movably arranged in the buffer groove 54 is provided on the outer side of the push-pull rod 45. A plurality of buffer springs 53 that contact the positioning ring 56 are also installed in the buffer groove 54. A positioning ring 2 58 is also provided on the outer side of the push-pull rod 45. The positioning ring 2 58 is always located outside the movable box 6, and a limiting ring 46 is also fixed to the end of the push-pull rod 45.

[0046] Furthermore, an extrusion spring 51 is installed on the outside of the push-pull rod 45 between the limit ring 46 and the end face of the movable sleeve 44, and a pressure sensor 52 that contacts the end of the extrusion spring 51 is also installed on one side end face of the limit ring 46. An alarm is also installed in the movable box 6, and the pressure sensor 52 and the alarm are electrically connected to the intelligent control cabinet 5.

[0047] Specifically, when the driving member works to push the movable box 6 outward, when the positioning ring 2 58 contacts the outer wall of the movable box 6, the driving member 59 continues to push outward, and the movable box 6 can move with it. At the same time, due to the meshing of the rack 1 on the outer side of the movable sleeve 44 and the gear 4 43, the gear 3 41 is driven to rotate with it, so that the cross bar 40 moves to one side. Due to the meshing of the rack 2 and the gear 2 39, the mounting shaft 37 drives the limit plate 35 to flip upward (such as Figure 6 shown).

[0048] When the driving member 59 drives the movable box 6 to move inward, since there is a gap between the movable sleeve 44 and the inner wall of the movable box 6, before the movable sleeve 44 moves to contact the inner wall of the movable box 6, the limiting plate 35 can be driven to flip downward and reset under the action of the linkage mechanism, so it will not affect the reset of the movable box 6.

[0049] And in specific use, if the wheel hits the upwardly flipped limit plate 35, it will drive the limit plate 35 to have a tendency to flip upward, so that the movable sleeve 44 moves to the side close to the driving member. At this time, the pressure sensor 52 detects that the pressure given by the extrusion spring 51 becomes smaller, and it will transmit a signal to the intelligent control cabinet 5. The intelligent control cabinet 5 immediately controls the alarm to sound an alarm, effectively reminding the driver to make adjustments.

[0050] For further information, please refer to Figure 6 A sleeve box 48 is fixed in the movable box 6, a piston chamber 49 and an annular chamber 50 are arranged in the sleeve box 48, and an air outlet 47 connected to the annular chamber 50 is also opened on the shell of the movable box 6. One end of the cross bar 40 penetrates and extends into the piston chamber 49 and is connected to the piston therein, and a horn is installed at the end of the air outlet 47. In this way, when a wheel hits and pushes the limit plate 35 to flip upward, the cross bar 40 moves to the right, pushing the airflow in the piston chamber to blow out quickly from the air outlet 47, thereby blowing the horn, which can effectively remind the driver to brake in time and adjust the vehicle position to avoid losing weight.

[0051] As an optional embodiment of the present invention, the gate mechanism includes telescopic brackets rotatably connected to opposite sides of the support frame 4, and a railing 10 connected to the ends of the two sets of telescopic brackets, and a plurality of distance sensors are installed on the railing 10, and the distance sensor is used to sense the distance between the front of the vehicle and the railing 10 to detect whether the vehicle is completely weighed. When weighing, the gate mechanism 10 rotates the railing 10 so that it is at a certain height from the ground, so as to facilitate the detection of whether the vehicle is completely weighed.

[0052] In order to facilitate the adjustment of the height of the handrail, the handrail 10 can be rotated to the groove on the lower weighing platform 3 when the gate is closed (such as Figure 1 As shown), the telescopic bracket includes a plate 12, a plate 2 14 and a telescopic rod 13 connecting the plate 12 and the plate 2 14. The railing 10 is rotatably connected between the two plates 12. A cleaning cylinder 9 is also fixed to the outside of the railing 10. Brush bristles 34 are distributed on the outside of the cleaning cylinder 9. The plate 2 14 and the support frame 4 are connected by a self-moving mechanism. The telescopic rod 13 can be an electric telescopic rod. Theoretically, if the electric telescopic rod 13 is long enough, a camera can also be installed on the railing 10 to facilitate the capture of the cargo situation in the vehicle compartment. The camera can be connected to the intelligent control machine through wireless signals.

[0053] In order to prevent sewage from flowing around during cleaning, this solution provides an annular groove around the top surface of the scale box 1, and a rubber enclosure 8 is installed in the groove. The rubber enclosure 8 can be inflated, and the height of the rubber enclosure 8 after expansion is higher than the top surface of the scale box 1. After the rubber enclosure 8 is expanded, a water leakage hole 23 is formed on the side close to the upper weighing platform 2.

[0054] In this solution, water spraying mechanisms are installed on opposite sides of the scale box 1. The water spraying mechanisms include a water pipe 21 movably connected to the side of the scale box 1, a swivel joint 63 connected to one end of the water pipe 21, and a connecting pipe 65 connected to the other end of the swivel joint 63. The other end of the connecting pipe 65 is connected to an external water source. The water pipe 21 is connected to a plurality of water outlet pipes 20 connected thereto. A nozzle is installed at the end of the water outlet pipe 20. A mounting gear 61 is also sleeved on the outside of the water pipe 21. A lifting drive 64 is fixed on the outside of the scale box 1. A lifting plate 62 is connected to the output end of the lifting drive 64. A rack 3 meshing with the mounting gear 61 is installed on the outside of the lifting plate 62. The lifting plate 62 is driven to lift and lower to drive the water pipe 21 to rotate, so that the nozzles at the ends of the water outlet pipes 20 spray water toward the top surface of the scale box 1.

[0055] A sewage recovery mechanism is also installed at the joint between the upper weighing platform 2 and the weighing box 1. The sewage recovery mechanism includes an open groove opened on one side of the upper weighing platform 2 adjacent to the weighing box 1, and a movable pipe 22 movably arranged in the open groove. One side of the movable pipe 22 can be sealed and contacted with the outer surface of the weighing box 1. The top shell of the movable pipe 22 is provided with a plurality of water inlet holes. End plates 24 are detachably installed at both ends of the movable pipe 22. A water outlet pipe 25 that can communicate with the inside of the movable pipe 22 is installed at the end plate 24, and the other end of the water outlet pipe 25 can be connected to an external sewage pipe.
