DETAILED DESCRIPTION

[0036] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0037] Example 1

[0038] like Figure 1~Figure 5 As shown, this embodiment provides a jacking device for a dump truck compartment, comprising:

[0039] Base frame 1,

[0040] An articulated frame 2, hingedly arranged on the base frame 1;

[0041] The carriage 3 is arranged on the articulated frame 2.

[0042] A lifting member 4, one end of which is hingedly arranged on the base frame 1, and a moving end of the lifting member 4 is hingedly arranged on the articulated frame 2. After the moving end of the lifting member 4 moves, it is used to drive the articulated frame 2 to rotate;

[0043] After the articulated frame 2 rotates, it is used to drive the carriage 3 to tilt and unload.

[0044] In this embodiment, in order to solve the problem in the related art that when the dump truck 3 is directly lifted by a lifting device and tilted to unload, the lifting is unstable, shaking is easy to occur, and even the lifting device or the truck 3 is damaged, the present scheme changes the original method of directly lifting the truck 3 by the lifting member 4 to installing the lifting member 4 on the base frame 1, driving the articulated frame 2 hingedly installed on the base frame 1 to rotate, thereby making the truck 3 on the articulated frame 2 complete the tilting unloading action, wherein the articulated frame 2 in this scheme is rotated left and right, that is, unloading from the side of the truck 3, compared with the traditional front and rear tilting unloading, the rotation angle in this scheme is smaller, the unloading is more thorough, and it has a higher practical value.

[0045] Furthermore, the articulated frame 2 has a rotating edge 5 and a lifting edge 6, and the lifting edge 6 has a plurality of slide grooves 7, and further includes:

[0046] There are a plurality of hinged members 8, each having a fixed end 9 and a hinged end 10, wherein the fixed end 9 is disposed on the base frame 1 at intervals, and the hinged end 10 is disposed on the rotating edge 5 at intervals and is hinged to the rotating edge 5;

[0047] There are a plurality of telescopic rods 11 , which are hingedly mounted on the base frame 1 and arranged at intervals on the base frame 1 . After the telescopic ends of the telescopic rods 11 are extended and retracted, they are correspondingly slidably mounted in the slide grooves 7 .

[0048] In this embodiment, in order to ensure that the articulated frame 2 can rotate freely on the base frame 1 and has a certain stability after the articulated frame 2 rotates, the rotating side 5 of the articulated frame 2 is connected to the base frame 1 through a hinge 8, and its lifting side 6 is connected to the base frame 1 through a telescopic rod 11. At the same time, since the telescopic rod 11 can adopt a hydraulic rod, when the articulated frame 2 rotates to the unloading angle, the telescopic rod 11 has a certain supporting force, which further ensures the stability of the unloading compartment 3 and has a certain practical value.

[0049] Further, a positioning component 12 is included, and the positioning component 12 includes:

[0050] There are a plurality of first positioning plates 13, all of which are arranged on the articulated frame 2. The plurality of first positioning plates 13 enclose a lifting positioning space 14, and the lifting positioning space 14 is used to position the lifting member 4 after resetting;

[0051] There are a plurality of second positioning plates 15 , all of which are disposed on the base frame 1 . The plurality of second positioning plates 15 are used to position the articulated frame 2 after it is reset.

[0052] Furthermore, the carriage 3 has a plurality of positioning grooves 16, and the positioning assembly 12 further includes:

[0053] There are a plurality of positioning blocks 17 , which are arranged at intervals on the hinge frame 2 and cooperate with the positioning grooves 16 .

[0054] In this embodiment, in order to further improve the positioning and installation effect of the car 3 on the rotating frame, this solution is provided with a plurality of positioning blocks 17 on one side of the rotating edge 5 of the articulated frame 2, which cooperate with a plurality of positioning grooves 16 at the bottom of the car 3, so that the car 3 has a positioning effect when installed and used, so that the practicality of this solution is further improved.

[0055] Furthermore, the carriage 3 also has a plurality of locking grooves 18 and a plurality of locking assemblies 19. The locking assemblies 19 include:

[0056] The top column 20 is slidably disposed in the positioning block 17. The top column 20 has a sliding end 21 and an abutting end 22. The sliding end 21 abuts against the positioning groove 16. After the carriage 3 rotates, it is used to drive the top column 20 to move;

[0057] There are several locking members 23, all of which are slidably disposed on the positioning block 17. The locking members 23 abut against the abutting end 22. After the sliding end 21 slides, it is used to drive the locking members 23 to extend out of or retract the locking groove 18;

[0058] The first elastic member 24 has one end disposed on the abutting end 22 and the other end disposed on the positioning block 17 . The first elastic member 24 is used to provide a force for restoring the top column 20 .

[0059] In this embodiment, during the tilting unloading process of the carriage 3, the gravity of the carriage 3 and the loaded goods causes a slight displacement of the carriage 3, which in turn exerts a certain pressure on the positioning block 17, while further reinforcing the stability of the carriage 3 during unloading. According to the above-mentioned characteristics, the present solution is provided with a top column 20 on the positioning block 17, which abuts against the positioning groove 16 of the carriage 3. The top column 20 is squeezed by the carriage 3 to move inward to push out the locking member 23 inside the positioning block 17, and then is plugged and matched with the locking groove 18 of the carriage 3 to complete the locking of the carriage 3 during unloading, thereby further improving the stability of the carriage 3. In particular, the present solution is provided with a first elastic member 24 in the positioning block 17 for providing a reset elastic force for the top column 20.

[0060] Furthermore, the carriage 3 also has a loading port, and further includes:

[0061] The baffle 26 is hingedly arranged on the carriage 3. After the baffle 26 is rotated, it is used to open or close the unloading port;

[0062] There are a plurality of second elastic members 27 , one end of which is arranged on the carriage 3 , and the other end is arranged on the baffle 26 . The second elastic member 27 is used to provide the baffle 26 with a force to close the unloading port.

[0063] In this embodiment, in order to facilitate the unloading of the carriage 3, a hinged baffle 26 is provided on the unloading port of the carriage 3. At the same time, the baffle 26 is connected to the carriage 3 by a second elastic member 27. The second elastic member can be a tension spring. When the baffle 26 is tilted to unload the carriage 3, the cargo slides and is pressed against the baffle 26 by the gravity of the cargo. After overcoming the elastic force of the tension spring, the unloading port is pushed open to complete the unloading. When the unloading is completed, the tension of the tension spring drives the baffle 26 to reset and close the unloading port. A snap-fit ​​locking pin can be provided on the carriage. When the unloading port is closed, the baffle 26 is fixed and locked by the snap-fit ​​locking pin. Through this solution, the stable operation of the opening and closing of the unloading port during the unloading process can be further improved, and the operations required for the operator to open or close the unloading port can be reduced.

[0064] Furthermore, the chassis 1 has an arc-shaped avoidance edge 28, and the arc-shaped avoidance edge 28 is used to avoid the installation of wheels.

[0065] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
