Description

Technical Field

[0001] The utility model belongs to the technical field of floor scales, and in particular relates to an unattended floor scale device. Background Art

[0002] When weighing at the port, port staff are generally required to be on site, because the traditional weighbridge system cannot be operated unmanned and the operating efficiency is relatively low.

[0003] According to relevant technical surfaces, in order to solve the above problems, unattended weighing devices are gradually replacing traditional manual operations. The devices can obtain vehicle model information, whether it is a regular vehicle or an extra-wide vehicle; in order to facilitate the passage of regular vehicles, two weighing scales are generally set up, one for entry and one for exit, and each weighing scale can weigh independently; however, when an extra-wide vehicle appears, the width of a single weighing scale will appear very compact or even insufficient.

[0004] Therefore, how to facilitate the weighing of extra-wide vehicles on the basis of conventional weighbridges is a problem that technicians in this field need to solve urgently. Utility Model Content

[0005] In order to solve the technical problems mentioned in the background technology, the utility model provides an unattended weighing device, which includes: an entry weighing device and an exit weighing device, both including: an identification gate and a release gate; a plurality of fences vertically arranged between the entry weighing device and the exit weighing device; a driving mechanism; and a control module; wherein when an extra-wide vehicle passes, the control module controls the driving mechanism to drive each fence to fall to the ground to allow the extra-wide vehicle to pass.

[0006] Furthermore, the driving mechanism comprises: a screw and a plurality of sliding blocks; wherein the sliding blocks are sleeved on the screw and are suitable for moving along the axial direction of the screw when the screw rotates.

[0007] Furthermore, the driving mechanism further comprises: a slide rail; wherein a protrusion is provided at the lower end of the sliding block, and the protrusion is located in the track of the slide rail.

[0008] Furthermore, the bottom of the fence is hinged; the fence is hinged to the corresponding sliding block through a connecting rod, and is suitable for being moved to the ground or erected by the sliding block.

[0009] Furthermore, both ends of the driving-in scale and the driving-out scale are provided with guide ramps.

[0010] Furthermore, an avoidance gap is left between the drive-in scale and the guide ramp; the width of the avoidance gap ranges from 10 mm to 15 mm.

[0011] Furthermore, the side wall of the drive-in scale is contracted inwardly toward the guide ramp and is provided with reinforcing ribs.

[0012] Furthermore, a camera for acquiring license plate data is provided in the identification barrier.

[0013] The beneficial effect of the utility model is that the driving-in scale and driving-out scale of the unattended weighing device weigh the conventional vehicles entering and leaving respectively, and the two are separated by a plurality of fences so as not to interfere with each other, and the conventional vehicles can be weighed efficiently; when an over-width vehicle passes, the fence falls to the ground, and the driving-in scale and the driving-out scale are connected, thereby expanding the width of the weighing scale, making it convenient for the over-width vehicles to pass through.

[0014] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by practicing the utility model. The purpose and other advantages of the utility model are realized and obtained by the structures particularly pointed out in the description and the drawings.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 , Figure 2 As shown, at least one embodiment provides an unattended weighing device, characterized in that it includes: an entry weighing scale 1 and an exit weighing scale 2, both including: an identification gate 11 and a release gate 12; a plurality of fences 3, vertically arranged between the entry weighing scale 1 and the exit weighing scale 2; a driving mechanism 4; and a control module; wherein when an extra-wide vehicle passes, the control module controls the driving mechanism 4 to drive each fence 3 to fall to the ground to allow the extra-wide vehicle to pass.

[0029] In some embodiments, the driving-in weighing scale 1 and the driving-out weighing scale 2 weigh the conventional vehicles entering and exiting respectively, and the two are separated by a plurality of fences 3 so as not to interfere with each other, thereby being able to efficiently weigh the conventional vehicles; when an over-width vehicle passes, the fence 3 falls to the ground, and the driving-in weighing scale 1 and the driving-out weighing scale 2 are connected, thereby expanding the width of the weighing scale and facilitating the passage of oversized vehicles.

[0030] like Figure 1 , Figure 2 As shown, in some embodiments, a camera 16 is provided in the identification gate 11 of the entering scale 1 for identifying the vehicle type to determine whether it is a conventional vehicle or an extra-wide vehicle. The determination method is a prior art and is not improved in this scheme. When the identification gate 11 of the entering scale 1 identifies the vehicle as a conventional vehicle, the control module controls the identification gate 11 of the entering scale 1 to lift the bar, and then the conventional vehicle drives onto the entering scale 1 for weighing, and after the weighing is completed, the release gate 12 lifts the bar; the same applies to the exiting scale 2.

[0031] In some embodiments, when the identification gate 11 entering the weighing scale 1 identifies the vehicle as an over-wide vehicle, there are no vehicles on the weighing scale 1 and the weighing scale 2 at this time, and the control module controls the driving mechanism 4 to drive each fence 3 to fall to the ground, and then the control module controls the identification gate 11 entering the weighing scale 1 and the release gate 12 exiting the weighing scale 2 to lift the bar synchronously, and the over-wide vehicle drives onto the weighing scale, one side of its tires is located on the entering weighing scale 1, and the other side of its tires is located on the exiting weighing scale 2, and the control module controls the two weighing scales together to weigh the over-wide vehicle (the control method and weighing method are prior art and are not improved). After the weighing is completed, the release gate 12 entering the weighing scale 1 and the identification gate 11 exiting the weighing scale 2 lift the bar synchronously.

[0032] like Figure 3 , Figure 4 As shown, in some embodiments, the driving mechanism 4 includes: a screw 41 and a plurality of sliding blocks 42, and a slide rail 43; wherein the sliding block 42 is sleeved on the screw 41, and a protrusion 44 is provided at the lower end of the sliding block 42, and the protrusion 44 is located in the track of the slide rail 43, that is, the sliding block 42 moves along the axial direction of the screw 41 when the screw 41 rotates.

[0033] In some embodiments, the bottom of the fence 3 is hinged, and the fence 3 is hinged to the corresponding sliding block 42 through a connecting rod 45. When the sliding block 42 moves, the fence 3 falls to the ground or stands up.

[0034] like Figure 5 As shown, in some embodiments, guide ramps 13 are provided at both ends of the driving-in scale 1 and the driving-out scale 2. Since the driving-in scale 1 and the driving-out scale 2 are set on the ground at a certain height, the guide ramps 13 facilitate vehicles to drive onto the scale.

[0035] In some embodiments, an avoidance gap 14 is left between the driving-in scale 1 and the guide ramp 13, and the width of the avoidance gap 14 ranges from 10 mm to 15 mm. The avoidance gap 14 prevents the driving-in scale 1 from contacting the guide ramp 13 and affecting the weighing accuracy.

[0036] In some embodiments, the side wall of the driving scale 1 shrinks inward toward the guide ramp 13, and the shrinkage point is located at the bottom, so that the surface gap width is still 10mm to 15mm, and the gap below can be expanded to about 100mm. At the same time, the supporting structure is strengthened by setting reinforcing ribs 15.

[0037] In summary, the driving-in scale 1 and the driving-out scale 2 of the unattended weighing device weigh the conventional vehicles entering and leaving respectively, and the two are separated by a plurality of fences 3 so as not to interfere with each other, and the conventional vehicles can be weighed efficiently; when an over-width vehicle passes, the fence 3 falls to the ground, and the driving-in scale 1 and the driving-out scale 2 are connected, thereby expanding the width of the weighing scale, making it convenient for the over-width vehicles to pass through.

[0038] The various devices selected in this application (components whose specific structures are not described) are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
