[0016] Compared with the prior art, the application has the following advantages and positive effects: 1) The goods limiting device comprises a group of clamping rollers eccentrically mounted on the two sides of the loading carriage, and on the basis of the clamping rollers, the device is further provided with a clamping abutting assembly, which comprises an abutting piece provided on the outer side of the clamping roller, an arc-shaped groove matched with the clamping roller is provided on the inner side of the abutting piece, and an air bag is mounted on the arc-shaped groove. After the clamping roller is eccentrically rotated to drive the abutting piece to contact the outer side wall of the goods, the clamping roller is limited from rotating by the limiting device, and then the air compressor is used to inject high-pressure gas into the air bag. When the pressure in the air bag reaches a set value p1, the air compressor stops operating, so that the abutting piece is tightly abutted against the outer side wall of the goods. The clamping roller is eccentrically mounted to effectively adapt to the clamping and fixing of goods of different widths, and the intervention of the movably arranged abutting piece ensures the contact between the clamping end and the goods, thereby preventing the goods from being excessively mechanically damaged due to the small clamping area.

[0017] On this basis, the application is further provided with a corresponding pressure one-way valve mounted on the air bag, and the opening pressure of the pressure one-way valve is p2, p2>p1. This is because: although the arrangement of the abutting piece effectively improves the contact between the clamping end and the goods, when a major bump occurs during transportation and causes the loading carriage to be excessively inclined, the goods will be pressed against the corresponding abutting piece, thereby causing the abutting piece to form obvious extrusion damage to the goods. The intervention of the pressure one-way valve can effectively release the pressure when the goods form excessive pressing force on the air bag, thereby forming a certain buffer to significantly reduce the extrusion damage to the goods.

Thus, the problem of insufficient limiting caused by the deflation of the pressure check valve is effectively prevented to ensure the practical effect of the present application.

[0021] 4) The abutting piece of the present application is fixed to the clamping roller through a group of annular binding straps arranged above and below, when the air bag is deflated to the normal pressure state, the annular binding straps are in a loose state and are sleeved on the clamping roller, when the air bag is inflated to the pressure value p1 and there is no shielding object outside the abutting piece, the annular binding straps are in a tension state and are sleeved on the clamping roller. Thus, the relative movement of the abutting piece and the clamping roller during the fixing of the goods can be effectively adapted, and the abutting piece can be effectively fixed through the annular binding straps when the goods are not fixed to further ensure the practical effect of the present application.

[0022] 5) The upper end of the clamping roller of the present application is fixedly connected with a fixing seat, a twisting member is fixedly installed on the upper part of the fixing seat, a limiting piece comprises a fixing ring connected to an installation shaft on the upper part, a plurality of corresponding insertion holes are uniformly arranged on the fixing ring, a plug is movably installed on the lower side of the fixing seat through a spring, the plug is matched with the insertion hole, a corresponding handle is swingably installed on the twisting member, and the end of the plug is connected to the handle through a corresponding steel wire rope. By holding the handle, the plug inserted into the insertion hole can be effectively pulled out, so that the clamping roller can be driven to rotate by pushing the twisting member, and holding the handle and pushing the twisting member can be performed at the same time, so that the operation convenience of the present application is effectively assisted.

[0023] 6) The bottom surface of the lifting tail plate of the present application is arranged in a planar manner, a group of corresponding limiting convex edges are fixedly connected to the top surface of the lifting tail plate on both sides to ensure that the lifting tail plate can be in contact with the ground when it is lowered in place, so that the goods can be more conveniently transferred to the lifting tail plate, and the overall rigidity of the lifting tail plate can be effectively ensured under the action of the limiting convex edges.

[0024] On the basis, the top of the limiting convex edge is provided in a slope shape, and a slope-shaped stop plate is swingably installed at the rear end of the lifting tail plate, the stop plate is driven by a group of stop plate driving oil cylinders installed on the limiting convex edge, and a corresponding photoelectric sensor is embedded on the stop plate. Through the slope setting of the limiting convex edge, the arrangement of the stop plate driving oil cylinder is facilitated, and the slope-shaped stop plate is set to more conveniently push the goods onto the lifting tail plate. After the goods are transferred to the lifting tail plate, the stop plate driving oil cylinder can be controlled to drive the stop plate to flip up, thereby cooperating with the limiting convex edge to effectively limit the goods, so as to prevent the goods from sliding down during the lifting of the stop plate, and to further ensure the practical effect of the present application.

DETAILED DESCRIPTION

[0033] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0034] Reference Figures 1-6 A vehicle for transporting precision articles, comprising a loading compartment 1 fixedly arranged on a corresponding moving vehicle body 2, a lifting tailgate 3 for lifting goods arranged on the rear side of the loading compartment 1 in a liftable manner, and a goods limiting device arranged in the loading compartment 1, the goods limiting device comprising: a set of clamping rollers 4 eccentrically arranged on both sides of the loading compartment 1, the clamping rollers 4 being respectively provided with a twisting member 5 for driving the clamping rollers 4 to eccentrically rotate and a limiter 6 for fixing the clamping rollers 4; a clamping abutting assembly 7 comprising an abutting member 701 arranged on the outer side of the clamping roller 4, the inner side of the abutting member 701 being provided with an arc-shaped groove matched with the clamping roller 4, a corresponding air bag 702 being fixedly arranged in the arc-shaped groove, the air inlet end of the air bag 702 being connected to a corresponding air compressor 9 through a pressure gauge 8, and a corresponding pressure one-way valve 10 being arranged on the air bag 702, the clamping roller 4 being eccentrically rotated to drive the abutting member 701 to contact the outer side wall of the goods 11, the limiter 6 being arranged to limit the rotation of the clamping roller 4, the air compressor 9 being arranged to inject high-pressure gas into the air bag 702, the air compressor 9 being stopped when the pressure in the air bag 702 reaches a set value p1, so as to tightly abut the abutting member 701 against the outer side wall of the goods 11, the opening pressure of the pressure one-way valve 10 being p2, and p2>p1; an electric controller 12 arranged to control the working process of the air compressor 9.

[0035] The goods limiting device comprises a set of eccentrically-rotating clamping rollers 4 installed on both sides of the loading compartment 1, and further comprises a clamping abutting assembly 7 comprising an abutting piece 701 installed on the outer side of the clamping roller 4, the inner side of the abutting piece 701 is provided with an arc-shaped groove matched with the clamping roller 4 and is installed with an air bag 702, after the clamping roller 4 rotates eccentrically to drive the abutting piece 701 to contact the outer side wall of the goods 11, the clamping roller 4 is prevented from rotating by the position limiter 6, and then the air compressor 9 is used to inject high-pressure gas into the air bag 702, when the pressure in the air bag 702 reaches the set value p1, the air compressor 9 stops to tightly abut the abutting piece 701 to the outer side wall of the goods 11. The eccentrically-installed clamping roller 4 effectively adapts to the clamping and fixing of goods 11 of different widths, and the intervention of the movably-installed abutting piece 701 ensures the contact between the clamping end and the goods 11, thereby preventing the goods 11 from being excessively mechanically damaged due to the small clamping area.

[0036] On this basis, the air bag 702 is further installed with a corresponding pressure one-way valve 10, the opening pressure of the pressure one-way valve 10 is p2, and p2>p1. This is because: although the abutting piece 701 effectively improves the contact between the clamping end and the goods 11, when the loading compartment 1 is excessively tilted due to major bumps during transportation, the goods 11 will be tilted and pressed against the corresponding abutting piece 701, thereby causing the abutting piece 701 to form obvious extrusion damage to the goods 11. The intervention of the pressure one-way valve 10 can effectively form pressure relief when the goods 11 form excessive pressing force on the air bag 702, thereby forming a certain buffer to obviously reduce the extrusion damage to the goods 11.

[0037] Therefore, the fixing of goods 11 of different specifications and widths can be effectively adapted, the operation convenience in the fixing process is extremely high, and the excessive extrusion damage to the goods 11 during the fixing process can be effectively prevented.

[0038] The air outlet end of the pressure one-way valve 10 is provided with a corresponding air flow sensor 13, the air flow sensor 13 is electrically connected to the electric controller 12, and the electric controller 12 is provided with a corresponding signal emission module; when the air flow sensor 13 detects that the gas flow output through the pressure one-way valve 10 reaches a set value Q1, the electric controller 12 controls the signal emission module to send an alarm signal to the receiving end. In the embodiment, the signal emission module adopts a Bluetooth module, and the receiving end is a cab control unit or a driver's mobile phone.

[0039] After a certain amount of pressure relief is generated in the pressure one-way valve 10, the driver is reminded to stop and check in time, and the deflated air bag 702 is inflated again to the set value p1 to re-form a stable limit for the goods 11 before re-transportation. Thus, the problem of insufficient limiting caused by pressure relief of the pressure one-way valve 10 is effectively prevented, and the practical effect of the present application is ensured.

[0040] The air bag 702 is respectively connected with a corresponding pressure relief valve 14. The eccentric rotation of the clamping roller 4 drives the abutting piece 701 to contact the outer side wall of the goods before the goods 11 are unloaded, and the pressure relief valve 14 is opened to deflate the air bag 702 to the normal pressure state, thereby ensuring the controllability of the present application during the limiting and fixing of the goods 11 and unloading.

[0041] The bottom side of the abutting piece 701 is respectively provided with a corresponding supporting roller, so that the abutting piece 701 is timely and conveniently moved adaptively when the clamping roller 4 is eccentrically rotated.

[0042] The abutting piece 701 is fixed to the clamping roller 4 by a set of annular bands 15 arranged above and below. When the air bag 702 is deflated to the normal pressure state, the annular bands 15 are in a loose state and are sleeved on the clamping roller 4. When the air bag 702 is pressurized to a pressure value p1 and there is no shielding object on the outer side of the abutting piece 701, the annular bands 15 are in a tension state and are sleeved on the clamping roller 4. Thus, the relative movement of the abutting piece 701 and the clamping roller 4 during the fixing of the goods 11 can be effectively adapted, and the abutting piece 701 can be effectively fixed by the annular bands 15 when the goods 11 are not fixed, thereby further ensuring the practical effect of the present application.

[0043] The two sides of the loading compartment 1 are respectively fixed with corresponding clamping roller mounting seats 16. The clamping roller 4 is eccentrically and rotatably mounted between the clamping roller mounting seats 16 by a set of corresponding mounting shafts 17. The upper end of the clamping roller 4 is fixedly connected with a corresponding fixed seat 18, and the twisting member 5 is fixedly installed on the upper part of the fixed seat 18.

[0044] The limiter 6 comprises a fixed annular piece 601 fixed to the mounting shaft 17 at the upper part. The fixed annular piece 601 is uniformly provided with a plurality of corresponding insertion holes. The lower side of the fixed seat 18 is movably installed with a corresponding bolt 602 adapted to the insertion hole by a spring 19. A corresponding handle 603 is swingably installed on the twisting member 5. The end of the bolt 602 is connected to the handle 603 by a corresponding steel wire rope.

[0045] By holding the handle 603, the plug 602 plugged in the plug hole can be effectively pulled out, so as to facilitate the rotation driving of the clamping roller 4 by pushing the twist member 5, and the handle 603 and the push twist member 5 can be operated simultaneously with one hand, so as to effectively assist in improving the operation convenience of the application.

The rear side of the loading compartment 1 is provided with a clearance groove 25 for forming a clearance for the mounting seat 21.

[0047] During the lifting process of the lifting tailgate 3, the piston rod ends of the lifting oil cylinders 23 are extended to drive the tailgate swing arms 22 to lift the lifting tailgate 3 upwards, and the flap oil cylinders 24 are quantitatively extended to keep the lifting tailgate 3 in a reasonable horizontal state, so as to ensure the stable lifting of the goods 11, and after the goods 11 are lifted in place, they are directly pushed into the loading compartment 1 by manual driving.

[0048] The bottom surface of the lifting tailgate 3 is provided in a planar manner, a group of corresponding limiting convex edges 26 are fixedly connected to the top surface of the lifting tailgate 3, so as to ensure that the lifting tailgate can be in contact with the ground when it is lowered in place, so that the goods can be more conveniently transferred to the lifting tailgate, and the overall rigidity of the lifting tailgate can be effectively ensured under the action of the limiting convex edges.

[0049] On this basis, the top of the limiting convex edge 26 is provided in a slope surface manner, and a slope surface stop plate 27 is swingably installed at the rear end of the lifting tailgate 3, the stop plate 27 is driven by a group of stop plate driving oil cylinders 28 installed on the limiting convex edge 26, and a corresponding photoelectric sensor 29 is embedded on the stop plate 27. The slope surface of the limiting convex edge 26 is arranged to facilitate the arrangement of the stop plate driving oil cylinders 28, and the slope surface stop plate 27 is arranged to more conveniently push the goods 11 onto the lifting tailgate 3, and after the goods 11 are transferred to the lifting tailgate 3, the stop plate driving oil cylinders 28 can be controlled to drive the stop plate 27 to flip up, so as to cooperate with the limiting convex edge 26 to effectively limit the goods 11, so as to prevent the goods 11 from slipping down during the lifting process of the stop plate 27, so as to further ensure the practical effect of the application.

[0050] The lifting tail plate 3 of the application can monitor the movement of the goods 11 in real time through the photoelectric sensor 29 during the lifting process. When the goods 11 move excessively, the lifting tail plate 3 stops lifting and checks the goods. After solving the movement problem of the goods, the lifting tail plate 3 can be lifted again, thereby effectively assisting to ensure the safety of the goods 11 during the lifting drive.
