Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0030] Combine the following Figure 1-Figure 8 The specific structure and working principle of the carrier of the transport vehicle of the present invention are described.

[0031] Figure 1 The three-dimensional structural diagram of the transport vehicle provided by the present invention is illustrated. Figure 2 One of the three-dimensional structural schematic diagrams of the carrier platform of the transport vehicle provided by the present invention is illustrated, such as Figures 1 to 3 As shown, the platform of the transport vehicle includes a platform body 100, a telescopic frame 200 and a driving component 300, and the platform body 100 is directly or indirectly connected to a guide assembly. The telescopic frame 200 and the guide assembly slide in cooperation along the length direction of the platform body 100. It can be imagined that the telescopic frame 200 can also be arranged on the top or side of the platform body 100, and slide in cooperation with the guide assembly in the length direction of the platform body 100. The driving component 300 is connected to the platform body 100 and the telescopic frame 200, and the driving component 300 is used to drive the telescopic frame 200 to switch between an extended state and a retracted state; in the extended state, the telescopic frame 200 extends from the end of the platform body 100 away from the vehicle body cab; in the retracted state, the telescopic frame 200 retracts into the platform body 100.

[0032] It can be understood that one end of the telescopic frame 200 can be extended to the farthest first position, and retracted to the closest second position, and a third position, a fourth position, and an Nth position (N is an integer) between the first position and the second position.

[0033] The telescopic frame 200 is set at the bottom of the platform body 100 as an example for explanation. The platform of the transport vehicle provided by the present invention drives the telescopic frame 200 to switch between the extended state and the retracted state through the driving component 300. When the length of the cargo does not exceed the length of the platform body 100, the driving component 300 drives the telescopic frame 200 to retract to the bottom of the platform body 100; when the length of the cargo exceeds the length of the platform body 100, the driving component 300 drives the telescopic frame 200 to extend from the end of the platform body 100 away from the vehicle body cab, and the telescopic frame 200 is used to carry the cargo that exceeds the platform body 100, so as to prevent the cargo that exceeds the platform body 100 from dragging on the ground, and there is no need to use a longer platform body 100 or a larger transport vehicle, which effectively reduces the use cost.

[0034] Especially when laying steel plates on loose terrain such as deserts to form a transportation channel, there will be a problem of different specifications of the steel plates. When transporting shorter steel plates, the telescopic frame 200 does not extend. When transporting longer steel plates, the telescopic frame 200 can be extended to an appropriate length.

[0035] In one embodiment of the present invention, Figure 2 As shown, the platform body 100 is a plate-like structure, and the platform body 100 is used to carry goods. A partition 130 is provided at one end of the platform body 100 close to the cab, which separates the space above the platform body 100 from the space in front, thereby avoiding the problem of collision between the cargo carried by the platform and the front structure. Figure 1 The middle partition 130 is vertically arranged, and the partition 130 can also be arranged at a predetermined angle relative to the stage body 100, and the partition 130 is welded to the stage body 100. Of course, the connection relationship between the partition 130 and the stage body 100 is not limited thereto, and bolt connection, plug connection or other connection methods can also be adopted.

[0036] In one embodiment of the present invention, Figure 3 The second schematic diagram of the three-dimensional structure of the carrier platform of the transport vehicle provided by the present invention is illustrated. Figure 8 The side cross-sectional structure diagram of the carrier of the transport vehicle provided by the present invention is illustrated as follows: Figure 3 and Figure 8 As shown, the guide assembly includes at least one guide groove 110, the guide groove 110 extends along the length direction of the stage body 100, and the guide groove 110 is slidably matched with the telescopic frame 200. Specifically, as Figure 3As shown, the cross-section of the guide groove 110 is rectangular, circular, elliptical, etc., and a rectangular shape is used as an example in this embodiment. The guide groove 110 is welded or bolted to the stage body 100. In this embodiment, the rectangular tube is the beam of the stage body 100. This design method can make full use of the space inside the beam and improve the compactness of the stage body 100. Of course, a guide groove 110 can also be set separately at the bottom of the stage body 100.

[0037] It should be noted that the specific structure of the guide groove 110 is not limited thereto, and may also be a circular tube or a tube body of other shapes.

[0038] In one embodiment of the present invention, Figure 4 The three-dimensional structural diagram of the telescopic frame provided by the present invention is illustrated as follows: Figure 4 As shown, the telescopic frame 200 includes a first crossbeam 210 and at least one longitudinal beam 220. The first crossbeam 210 is arranged along the width direction of the platform body 100. Preferably, the first crossbeam 210 is perpendicular to the longitudinal beam 220. The end of the longitudinal beam 220 away from the vehicle body cab is connected to the first crossbeam 210. Specifically, the end of the longitudinal beam 220 away from the vehicle body cab is welded to the first crossbeam 210. Of course, the end of the longitudinal beam 220 away from the vehicle body cab can also be connected to the first crossbeam 210 by bolt connection or integral molding. The longitudinal beam 220 can be slidably clamped in the guide groove 110. The longitudinal beam 220 is guided by the guide groove 110, so that the longitudinal beam 220 can move along the length direction of the platform body 100.

[0039] It should be noted that the longitudinal beam 220 is a rectangular tube, but the shape of the longitudinal beam 220 is not limited thereto, and may also be a circular tube or a tube of other shapes. The longitudinal beam 220 matches the guide groove 110 .

[0040] In one embodiment of the present invention, Figure 3 As shown, the guide assembly includes two guide grooves 110, the two guide grooves 110 are arranged in parallel, the two guide grooves 110 are arranged at intervals along the width direction of the platform body 100, and the sizes of the two guide grooves 110 are equal, that is, the length, width and height of the two guide grooves 110 are equal. The telescopic frame 200 includes two longitudinal beams 220, the sizes of the two longitudinal beams 220 are equal, the width and height of the longitudinal beams 220 are similar to the width and height of the guide groove 110, and the two longitudinal beams 220 are clamped in the guide groove 110 in a one-to-one correspondence.

[0041] In one embodiment of the present invention, Figure 4As shown, the telescopic frame 200 also includes a second crossbeam 230, which is arranged between the two longitudinal beams 220, and the second crossbeam 230 is arranged along the width direction of the platform body 100. Preferably, the second crossbeam 230 is perpendicular to the longitudinal beam 220. The second crossbeam 230 enhances the overall structural strength of the telescopic frame 200. The two guide grooves 110 are provided with a strip through hole 111 on the side facing each other, and the length and width of the two strip through holes 111 are equal. The two strip through holes 111 are symmetrically arranged, and the two strip through holes 111 extend along the length direction of the platform body 100. The strip through holes 111 are arranged to allow the second crossbeam 230 to be connected to the longitudinal beam 220 in the guide groove 110. The two ends of the second crossbeam 230 pass through the corresponding strip through holes 111 and are connected to the two longitudinal beams 220 one by one. The second crossbeam 230 and the longitudinal beam 220 can be welded or bolted.

[0042] In one embodiment of the present invention, Figure 3 As shown, a third crossbeam 250 is disposed at the bottom of the stage body 100, and the driving component 300 is pivotally connected to the second crossbeam 230 and the third crossbeam 250. Figure 3 As shown, the third crossbeam 250 is arranged along the width direction of the stage body 100, the third crossbeam 250 is parallel to the second crossbeam 230, and the third crossbeam 250 is located on the side of the second crossbeam 230 away from the first crossbeam 210. The two ends of the third crossbeam 250 are welded to the two guide grooves 110, and of course, they can also be connected to the two guide grooves 110 by bolts. The structure of the third crossbeam 250 can also be replaced by a hinge ear with a pin shaft hole. The third crossbeam 250 or the hinge ear of the pin shaft hole is used to pivotally connect one end of the driving component 300.

[0043] The driving component 300 includes a cylinder, a cylinder body of the cylinder is hinged to the third cross beam 250, and a telescopic rod of the cylinder is hinged to the second cross beam 230. When the cylinder is controlled to extend, the cylinder drives the telescopic frame 200 to extend from the end of the platform body 100 away from the vehicle body cab; when the cylinder is controlled to shorten, the telescopic frame 200 retracts to the bottom of the platform body 100.

[0044] In one embodiment of the present invention, Figure 2As shown, the platform of the transport vehicle also includes a plurality of limiting components 500, which are spaced apart on both sides of the platform body 100. The limiting components 500 are suitable for switching between an unfolded state and a folded state. In the unfolded state, the limiting components 500 are used to limit the cargo; in the folded state, the limiting components 500 lose their limiting effect on the cargo. Since the guardrails installed on both sides of the existing platform are fixed, the distance between the guardrails is also fixed and cannot be adjusted according to the width of the cargo to be transported. When it is needed, the guardrail needs to be plugged in, and when it is not needed, the guardrail needs to be removed, and the use process is relatively cumbersome. The platform of the transport vehicle provided by the present invention, when it is necessary to use the limiting component 500, the limiting component 500 is placed in an expanded state so that the limiting component 500 can limit the goods and prevent the goods from falling from the platform body 100; when the limiting component 500 is not used, the limiting component 500 is placed in a folded state so that the limiting component 500 loses its limiting effect on the goods. Since the limiting component 500 is in a folded state, it will not affect the loading and unloading of the goods, and there is no need to remove the limiting component 500.

[0045] like Figure 1 and Figure 2 As shown, a plurality of limiting components 500 are provided on both sides of the platform body 100, and the number of limiting components 500 on both sides of the platform body 100 is equal, and the distance between two adjacent limiting components 500 can be the same or different, which is specifically determined according to the type of goods being transported. Preferably, when the longitudinal beam 220 is in the extended state, the limiting component 500 can also be provided at the end of the longitudinal beam 220 away from the vehicle body cab and on the cross beam.

[0046] In one embodiment of the present invention, Figure 6 One of the three-dimensional structural schematic diagrams of the limiting component provided by the present invention is illustrated. Figure 7 The second schematic diagram of the three-dimensional structure of the limiting component provided by the present invention is illustrated as follows: Figure 6 and Figure 7 As shown, the limiting component 500 includes a fixing member 510, which is a tubular structure and is horizontally arranged to fix the limiting member 520. Of course, the specific structural form of the fixing member 510 is not limited thereto, and can also be a rod-shaped structure or other structural types.

[0047] The side wall of the guide groove 110 is provided with a plurality of first positioning holes 112 at intervals along the length direction of the stage body 100. The first positioning holes 112 are circular holes. Of course, the shape of the first positioning holes 112 is not limited thereto, and may also be square holes or through holes of other shapes. The inner diameter of the first positioning hole 112 is greater than the outer diameter of the fixing member 510 to ensure that the fixing member 510 can pass freely. The distance between two adjacent first positioning holes 112 may be the same or different, and is determined according to actual needs.

[0048] The longitudinal beam 220 is provided with a plurality of second positioning holes 113 at intervals along the length direction of the stage body 100. The number of the second positioning holes 113 is the same as the number of the first positioning holes 112, and the positions of the second positioning holes 113 correspond to the positions of the first positioning holes 112. The second positioning holes 113 are circular holes. Of course, the shape of the second positioning holes 113 is not limited thereto, and may also be square holes or through holes of other shapes. The fixing member 510 is provided through the corresponding first positioning hole 112 and the second positioning hole 113 to fix the limiting component 500.

[0049] One end of the limiting member 520 is hinged to one end of the fixing member 510 by a pin, and a positioning portion 530 is provided at one end of the limiting member 520. The positioning portion 530 is integrally formed with the limiting member 520, or it can be a separate component provided at one end of the limiting member 520. A plurality of limiting holes 120 are provided at intervals on both sides of the carrier body 100, and the number of the limiting holes 120 on each side is the same, and the number of the limiting holes 120 is the same as the number of the first positioning holes 112, and the positions of the limiting holes 120 correspond to the positions of the first positioning holes 112 one by one. The limiting holes 120 are bar-shaped through holes 111, and the limiting holes 120 extend along the width direction of the carrier body 100. The length of the limiting holes 120 is greater than the length of the limiting member 520, so that the limiting member 520 can be received in the limiting holes 120 and the limiting member 520 can move in the limiting holes 120.

[0050] In the unfolded state, the limiting member 520 extends from the limiting hole 120, and the positioning portion 530 abuts against one end of the fixing member 510, and the limiting member 520 is used to limit the cargo; in the folded state, the limiting member 520 is received in the limiting hole 120, and the limiting member 520 loses the limiting effect on the cargo. Since the limiting member 520 is received in the limiting hole 120 in the folded state, it will not affect the loading and unloading of the cargo. When in use, the limiting member 520 only needs to be unfolded to play a limiting role, which is more convenient to use and improves transportation efficiency.

[0051] In one embodiment of the present invention, the limiting component 500 also includes a positioning pin, and the fixing member 510 is provided with a plurality of third positioning holes 540 at intervals along its length direction. The third positioning holes 540 may be through holes or blind holes. The plurality of third positioning holes 540 are on the same straight line, and the distances between two adjacent third positioning holes 540 may be the same or different. The positioning pin is inserted into different third positioning holes 540 to adjust the position of the limiting member 520 in the width direction of the platform body 100. By adjusting the positions of the limiting members 520 on both sides in the width direction of the platform body 100, the transportation requirements of goods of different widths can be adapted, and there is no need to use a larger transport vehicle, which effectively reduces the use cost.

[0052] When in use, adjust the relative position of the telescopic frame 200 and the carrier body 100, then insert the limit member 520 into the first positioning hole 112 and the second positioning hole 113 to fix the position of the telescopic frame 200, and then insert the positioning pin into different third positioning holes 540 to adjust the position of the limit member 520 in the width direction of the carrier body 100.

[0053] In one embodiment of the present invention, Figure 5 The schematic diagram of the partial enlarged structure of the telescopic frame provided by the present invention is illustrated as follows: Figure 4 and Figure 5 As shown, a plurality of trigger sensors 240 are spaced apart at the upper portion of the longitudinal beam 220 away from one end of the vehicle body cab. The plurality of trigger sensors 240 are spaced apart along the length direction of the platform body 100. The distance between two adjacent trigger sensors 240 is equal. The plurality of trigger sensors 240 are electrically connected to the driving component 300 by signals. When the oil cylinder drives the telescopic frame 200 to retract along the length direction of the platform body 100, the trigger sensor 240 contacts the lower edge of the platform body 100 away from the vehicle cab (the top of the trigger sensor 240 is slightly higher than the top of the platform body 100), and the trigger sensor 240 outputs an electrical signal to the oil cylinder to control the oil cylinder to stop moving. At this time, the first positioning hole 112 and the second positioning hole 113 are aligned. If the extended length of the telescopic frame 200 is not the required length at this time, the control device on the transport vehicle can continue to control the retraction of the telescopic frame 200 until the extended length of the telescopic frame 200 reaches the required length, and then the limit member 520 is inserted into the first positioning hole 112 and the second positioning hole 113 to fix the telescopic frame 200.

[0054] It should be noted that the trigger sensor 240 is provided with a compression spring. When the trigger sensor 240 contacts the lower edge of the end of the platform body 100 away from the vehicle cab, the trigger sensor 240 will be squeezed and retracted into the longitudinal beam 220.

[0055] The present invention further provides a transport vehicle, which includes a vehicle body 400 and a platform of the transport vehicle described in any one of the above embodiments, wherein the platform of the transport vehicle is arranged on the upper part of the vehicle body 400 .

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
