Description

Technical Field

[0001] The utility model relates to the technical field of dump trucks, in particular to a driving mechanism for a dump truck carriage. Background Art

[0002] A dump truck carriage refers to a vehicle part specifically designed for transporting and unloading bulk materials. Dump trucks are usually used in industries such as construction, mining, and agriculture, and can conveniently unload goods at designated locations. The dump truck carriage can be tilted through a hydraulic system, and the goods can be smoothly unloaded under the action of gravity. The use of dump trucks improves transportation efficiency and reduces the labor intensity of manual unloading, and is one of the indispensable equipment in modern logistics and construction operations.

[0003] However, most of the existing dump truck carriages are driven by hydraulic devices, and the hydraulic devices can bear greater gravity. However, most of such existing driving mechanisms have relatively low functionality in actual use. Before tilting the dump truck carriage, manual operation is usually required to release the restriction of the cover plate behind the carriage before the objects in the carriage can be dumped out. Moreover, after completion, the cover plate behind the carriage needs to be restricted to prevent the cover plate from automatically opening under force. Therefore, it is urgent to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a driving mechanism for a dump truck carriage is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A driving mechanism for a dump truck carriage includes a vehicle frame. Cross beams are symmetrically arranged on both sides of the surface of the vehicle frame. A connecting plate is horizontally and fixedly connected between the two cross beams. A carriage is rotatably connected to the top of the vehicle frame. A rotating mechanism for rotating the carriage is arranged inside the vehicle frame. A bottom plate is fixedly connected to the bottom of the carriage. One end of the carriage is open. A baffle is rotatably connected to one end of the carriage. The baffle is matched with the opening at one end of the carriage. A switching mechanism for the baffle is arranged on the top of the vehicle frame. Through the mutual cooperation of a support rod and a connecting rod, when the carriage is flipped during use, the baffle will also be rotated in the opposite direction, so as to open one end of the carriage, which can improve the use effect of the device and also improve the sealing performance of the carriage.

[0007] Preferably, the rotating mechanism includes connecting blocks. There are two connecting blocks, and both of the two connecting blocks are fixedly connected to the bottom of the bottom plate near one end of the opening. The two connecting blocks are respectively hinged to one end of the tops of the two cross beams. There are two connecting grooves arranged on the top of the connecting plate. Two hydraulic telescopic rods are installed on the top of the vehicle frame. The bottom ends of the two hydraulic telescopic rods are respectively rotatably connected to the interiors of the two connecting grooves. The two hydraulic telescopic rods are both arranged obliquely. The top ends of the two hydraulic telescopic rods are both rotatably connected to the bottom of the bottom plate. A support bar is arranged at the bottom of the carriage. The support bar is fixedly connected to the bottom of the bottom plate. The support bar cooperates with the top of the connecting plate to limit the rotation of the carriage. At the same time, the carriage can be rotated through the arrangement of the two hydraulic telescopic rods.

[0008] Further, the switching mechanism includes support rods. There are two support rods, and the two support rods are respectively rotatably connected to the symmetric two sides of the surface of the carriage. The two support rods are respectively fixedly connected to both ends of the baffle. Fixed shafts are fixedly connected to the opposite two sides of the two support rods. Connecting holes are arranged on the symmetric two sides of the surface of the carriage. The two fixed shafts are respectively rotatably connected to the interiors of the two connecting holes. Support plates are fixedly connected to the symmetric two sides of the surfaces of the two cross beams. Support blocks are fixedly connected to the tops of the two support plates. Connecting rods slide on the symmetric two sides of the surface of the carriage. The bottom ends of the two connecting rods are respectively rotatably connected to the surfaces of the two support blocks. The top ends of the two connecting rods are respectively rotatably connected to the ends of the two support rods away from the baffle, which is used to limit the rotation of the baffle. Thus, when the carriage rotates, the baffle will rotate under the connection of the two connecting rods.

[0009] The beneficial effects of the present utility model are as follows:

[0010] 1. When in use, when the two hydraulic telescopic rods are extended, the bottom plate and one end of the carriage can be driven to rotate upward, and the carriage can be lifted. At this time, under the pulling of the two connecting rods, the two support rods will rotate, so that the baffle can be slid upward, making it more convenient to pour out the objects inside the carriage. At the same time, there is no need to manually operate the baffle, improving the use convenience.

[0011] 2. When the carriage is placed in a horizontal state again, through the arrangement of the two connecting rods and the two support rods, the baffle will slide at one end of the carriage, so that one end of the carriage can be blocked without manual interference, and the objects inside the carriage will not fall out, thus improving the use effect of the device.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] Referring to Figures 1 - 4 , a drive mechanism for a dump truck carriage includes a vehicle frame 1. Cross beams 11 are symmetrically arranged on both sides of the surface of the vehicle frame 1. A connecting plate 12 is horizontally and fixedly connected between the two cross beams 11. A carriage 2 is rotatably connected to the top of the vehicle frame 1. A rotating mechanism for rotating the carriage 2 is provided inside the vehicle frame 1. A bottom plate 21 is fixedly connected to the bottom of the carriage 2. One end of the carriage 2 is open. A baffle 3 is rotatably connected to one end of the carriage 2. The baffle 3 cooperates with the opening at one end of the carriage 2. A switching mechanism for the baffle 3 is provided at the top of the vehicle frame 1. Through the mutual cooperation of the support rod 31 and the connecting rod 33, when the carriage 2 is flipped during use, the baffle 3 will also be rotated in the opposite direction, so as to open one end of the carriage 2, thereby improving the use effect of the device and also improving the sealing performance of the carriage 2.

[0019] Referring to Figure 1 , Figure 2 and Figure 3, in a preferred embodiment, the rotating mechanism includes connecting blocks 24. There are two connecting blocks 24, and both of the two connecting blocks 24 are fixedly connected to the bottom of the bottom plate 21 near one end of the opening. The two connecting blocks 24 are respectively hinged to one end of the tops of the two cross beams 11. Two connecting grooves 14 are arranged on the top of the connecting plate 12. Two hydraulic telescopic rods 4 are installed on the top of the vehicle frame 1. The bottom ends of the two hydraulic telescopic rods 4 are respectively rotatably connected to the interiors of the two connecting grooves 14. The two hydraulic telescopic rods 4 are both inclined. The top ends of the two hydraulic telescopic rods 4 are respectively rotatably connected to the bottom of the bottom plate 21. A support bar 23 is arranged at the bottom of the carriage 2. The support bar 23 is fixedly connected to the bottom of the bottom plate 21. The support bar 23 cooperates with the top of the connecting plate 12 to limit the rotation of the carriage 2. At the same time, the rotation of the carriage 2 can be achieved through the arrangement of the two hydraulic telescopic rods 4.

[0020] Referring to Figure 2 and Figure 4 , in a preferred embodiment, the switch mechanism includes support rods 31. There are two support rods 31, and the two support rods 31 are respectively rotatably connected to the symmetric two sides of the surface of the carriage 2. The two support rods 31 are respectively fixedly connected to both ends of the baffle 3. Fixed shafts 32 are fixedly connected to the opposite sides of the two support rods 31. Connecting holes 22 are arranged on the symmetric two sides of the surface of the carriage 2. The two fixed shafts 32 are respectively rotatably connected to the interiors of the two connecting holes 22. Support plates 13 are fixedly connected to the symmetric two sides of the surfaces of the two cross beams 11. Support blocks 15 are fixedly connected to the tops of the two support plates 13. Connecting rods 33 slide on the symmetric two sides of the surface of the carriage 2. The bottom ends of the two connecting rods 33 are respectively rotatably connected to the surfaces of the two support blocks 15. The top ends of the two connecting rods 33 are respectively rotatably connected to the ends of the two support rods 31 far from the baffle 3, which is used to limit the rotation of the baffle 3. Thus, when the carriage 2 rotates, the baffle 3 will rotate under the connection of the two connecting rods 33.

[0021] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: In actual use, through the mutual cooperation of the support rod 31 and the connecting rod 33, when the carriage 2 is flipped during use, the baffle 3 will also rotate in the opposite direction, thereby realizing the opening of one end of the carriage 2, which can improve the use effect of the device and also improve the sealing performance of the carriage 2. When in use, two hydraulic telescopic rods 4 can be driven to extend or contract. At this time, under the connection of the two connecting blocks 24, the bottom plate 21 and the carriage 2 will rotate simultaneously, and at this time, the objects inside the carriage 2 will be poured out. At the same time, when the bottom plate 21 and the carriage 2 are rotating, under the connection of the two connecting rods 33, one end of the two support rods 31 will be pulled, causing the two support rods 31 to rotate around the two fixed shafts 32 as the central axes, and thus the baffle 3 will slide upward. At this time, the baffle 3 will open one end of the carriage 2, making it more convenient to pour out the objects inside the carriage 2. When the carriage 2 is in a lying state, the baffle 3 will also, due to the settings of the two support rods 31 and the two connecting rods 33, block one end of the carriage 2.

[0022] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "above" etc. can be used here to describe the spatial positional relationship between one device or feature and other devices or features as shown in the figures. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figure is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "beneath" other devices or structures. Thus, the exemplary term "above" can include both the orientation of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0023] It should be noted that the terms used here are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.
