[0002] In the technology known to the inventor, a windshield is usually provided in front of the support platform of a transport vehicle. The windshield has a relatively large height, which will cause a large wind resistance to the progress of the transport vehicle. To solve this technical problem, the windshield can be tilted backward so that the windward surface of the windshield becomes an inclined plane, thereby reducing the wind resistance. However, after the windshield is tilted backward, its top is directly above the front end of the support platform, and the loading area of the support platform will be affected, especially the loading of large goods such as cargo boxes will be affected.

[0003] Therefore, it is necessary to design a new type of support device to solve the above technical problems. Summary of the Utility Model

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0031] The object of the present utility model is to provide a slip support device for a transport vehicle and a transport vehicle. By providing a slip bracket that can slide, when the windshield tilts backward to reduce the wind resistance during the driving of the transport vehicle, it can still ensure that the support part has strong loading capacity. Also, after the mother vehicle loads the sub-vehicle, since the body of the sub-vehicle is too long, the tail of the sub-vehicle's slip bracket is exposed from the tail of the mother vehicle, resulting in the overall length of the mother-and-sub vehicles being excessive and making it inconvenient to transport the sub-vehicle.

[0032] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Embodiment 1:

[0034] As Figures 1 to 6 shown, this embodiment provides a slip support device for a transport vehicle, including a fixed bracket 1 and a slip bracket 2. The fixed bracket 1 is used to be fixed on the chassis of the transport vehicle; the slip bracket 2 is arranged above the fixed bracket 1, and the slip bracket 2 is slidably connected to the fixed bracket 1 along the driving direction of the transport vehicle; the top of the slip bracket 2 has a support part for supporting goods.

[0035] The slip support device for a transport vehicle in this embodiment is applied to a transport vehicle with a windshield 3, and the windshield 3 is located in front of the slip support device for a transport vehicle. Regarding the structural setting of the windshield 3 on the transport vehicle and the driving mechanism for tilting the windshield 3, this embodiment will not be introduced.

[0036] Before the transport vehicle moves forward, the slip bracket 2 slides backward to make way for the backward tilting movement of the windshield 3. Then, goods can be loaded onto the support part of the slip bracket 2, or other transport vehicles can be loaded to form mother-and-sub vehicles. The transport vehicle providing the loading function is the mother vehicle, and the transport vehicle being loaded is the sub-vehicle. Since the slip bracket 2 slides backward, when loading goods or the sub-vehicle, the goods or the sub-vehicle can be as close as possible to the front end of the support part and will not interfere with the backward-tilted windshield 3, as Figure 7 shown. Therefore, in this embodiment, by providing a slip bracket 2 that can slide, when the windshield 3 tilts backward to reduce the wind resistance during the driving of the transport vehicle, it can still ensure that the support part has strong loading capacity. When loading the sub-vehicle to form mother-and-sub vehicles, the windshield 3 on the sub-vehicle resets and does not tilt backward, and the slip bracket 2 does not need to slide backward. Or rather, after the sub-vehicle unloads the goods, the windshield 3 of the sub-vehicle resets, and the slip bracket 2 slides forward to shorten the overall vehicle length of the sub-vehicle, avoiding the problem that after the mother vehicle loads the sub-vehicle, since the body of the sub-vehicle is too long, the tail of the sub-vehicle's slip bracket 2 is exposed from the tail of the mother vehicle, resulting in the overall length of the mother-and-sub vehicles being excessive and making it inconvenient to transport the sub-vehicle.

[0037] AsFigure 1 , Figure 2 As shown, in this embodiment, a support plate 4 for supporting goods is fixed to the top of the sliding bracket 2. A wheel receiving groove 5 is provided on the support plate 4. The number and positions of the wheel receiving grooves 5 correspond to the number of wheels of the transport sub-vehicle and are arranged at intervals. In this embodiment, there are 4 wheel receiving grooves 5. The width of the wheel receiving groove 5 can be 1.5 to 2 times, or even more, the width of the wheels of the sub-vehicle. On the one hand, it is to facilitate the correspondence between the wheels of the sub-vehicle and the wheel receiving groove 5, and on the other hand, it is to adapt to sub-vehicles with different wheel widths and improve its adaptability. The two ends of the wheel receiving groove 5 are in arc transition with the supporting surface of the support plate 4. The deepest part of the wheel receiving groove 5 can be 50 mm to 80 mm deep, and the specific depth of the wheel receiving groove 5 can be adjusted according to the size of the wheels of the sub-vehicle. The setting of the vehicle receiving groove can reduce the severity of the front-back shaking of the sub-vehicle on the mother vehicle; in cooperation with other sub-vehicle fixing devices, it can improve the transportation stability of the sub-vehicle on the mother vehicle. Taking the vertical plane where a line with the lowest position at the bottom of the wheel receiving groove 5 is located as the reference plane, in the driving direction of the transport vehicle, the length of the front side part of the reference plane in the wheel receiving groove 5 is less than the length of the rear side part of the reference plane, as Figure 4 shown. In other words, the inclination degree of the wall surface on the front side of the reference plane in the wheel receiving groove 5 is greater than that of the wall surface on the rear side of the reference plane, which can further avoid the possibility that the sub-vehicle moves forward due to inertia caused by braking.

[0038] As an implementation manner, a cargo box connection mechanism 6 is provided on the top of the sliding bracket 2. The cargo box connection mechanism 6 includes an internal thread hole 7, as Figure 3 shown. The internal thread hole 7 is used to connect the threaded column on the cargo box. The cargo box connection mechanism 6 can specifically be a fixing block with an internal thread hole 7, and the fixing block is arranged on the lower surface of the support plate 4. Through holes 14 are provided on the support plate 4 corresponding to the internal thread holes 7.

[0039] In order to connect the fixed bracket 1 to the vehicle chassis, a fixing plate 8 is vertically arranged at the bottom of the fixed bracket 1, and fixing holes 9 are provided on the fixing plate 8. A plurality of fixing plates 8 are arranged at intervals from front to back and are distributed on both sides of the bottom of the fixed bracket 1. The fixing plate 8 is fixed to the vehicle chassis by using rivets or bolts, as Figure 2 , Figure 6 shown.

[0040] As one embodiment, the fixed bracket 1 and the sliding bracket 2 are connected via a sliding mechanism, and the sliding mechanism includes a slide groove 10 and a track 11 slidably arranged inside the slide groove 10; the slide groove 10 is fixedly connected to the fixed bracket 1 or the sliding bracket 2; the track 11 is fixedly connected to the sliding bracket 2 or the fixed bracket 1. That is, when the slide groove 10 is fixedly connected to the fixed bracket 1, the track 11 is fixedly connected to the sliding bracket 2; when the slide groove 10 is fixedly connected to the sliding bracket 2, the track 11 is fixedly connected to the fixed bracket 1. In this embodiment, a structural form can be selected in which the track 11 is fixed to the side of the fixed bracket 1, and the slide groove 10 is fixed to the bottom of the sliding bracket 2. In addition, the slide groove 10 is a horizontally placed U-shaped structure, and its side is provided with an opening for avoiding the fixed bracket 1, such as Figure 5 At the same time, the arrangement of the slide groove 10 can also limit the vertical position of the sliding bracket 2 to prevent the front end from tilting upward due to the increase in the rear end weight after the sliding bracket 2 slides backward.

[0041] In order to avoid excessive wear between the track 11 and the slideway 10, in this embodiment, the surface of the track 11 that matches the slideway is provided with a wear-resistant sheet 12, and the wear-resistant sheet 12 abuts against the slideway 10. The wear-resistant sheet 12 can be a metal wear-resistant sheet 12 or a ceramic wear-resistant sheet 12.

[0042] As an implementation mode, the present embodiment further includes a telescopic mechanism 13 that can be telescoped along the travel direction of the transport vehicle, the fixed end of the telescopic mechanism 13 is connected to the fixed bracket 1 or the sliding bracket 2, and the telescopic end of the telescopic mechanism 13 is connected to the sliding bracket 2 or the fixed bracket 1. The telescopic mechanism 13 can be manually controlled, or can be automatically or semi-automatically controlled by a control device and an electric device. The telescopic mechanism 13 can be an electric mechanism, such as an electric telescopic rod, a screw nut structure, etc., or a hydraulic telescopic rod. As a specific example, the telescopic mechanism 13 is an electric telescopic rod, the fixed end of the electric telescopic rod is fixedly connected to the fixed bracket 1, and the telescopic end of the electric telescopic rod is fixedly connected to the bottom of the sliding bracket 2.

[0043] Embodiment 2:

[0044] This embodiment discloses a transport vehicle, including a chassis and a transport vehicle sliding support device as in Embodiment 1, which is arranged on the chassis. In this embodiment, the transport vehicle also includes a windshield 3, which is located in front of the transport vehicle sliding support device. The windshield 3 has a function of tilting backwards, which can reduce the wind resistance of the transport vehicle during its travel. The specific structure of the windshield 3 and the driving device that drives the windshield 3 to tilt backwards can all adopt existing devices. For example, the bottom end of the windshield 3 is fixed on a rotating shaft, and the rotating shaft is drivingly connected to a rotating driving device.
