Technical Field

[0001] This utility model relates to the field of dump truck technology, and in particular to a dump truck frame. Background Technology

[0002] In the existing field of dump truck technology, when loading goods into the dump truck's cargo box frame, the weight of the goods and the impact force of falling will have a significant impact on the vehicle's chassis and other components. Especially for some heavy goods, frequent loading impacts may lead to damage to chassis components, reducing the service life of the dump truck and increasing maintenance costs. In addition, when loading goods on uneven ground, the vehicle's stability will also be affected, further aggravating the impact on the vehicle. Currently, some dump trucks have adopted some shock absorption measures, such as installing shock-absorbing springs or dampers in the chassis, but these measures often only provide partial buffering and cannot fundamentally and effectively solve the problem of instantaneous high-intensity impacts during loading. Therefore, a dump truck frame is proposed to address the above problems. Utility Model Content

[0003] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A dump truck frame includes a truck body. Fixed rods are attached to both the front and rear ends of the truck body. A dual-axis motor is fixedly connected to the center of the inner side of each fixed rod. A threaded shaft is fixedly connected to the end of the main shaft of the dual-axis motor and is rotatably connected to the fixed rod. A slider is helically connected to the outer side of the threaded shaft and is slidably connected to the fixed rod. A rotating rod is rotatably connected to the bottom end of the slider via a rotating shaft. A support rod that contacts the truck body is rotatably connected to the other end of the rotating rod via a rotating shaft. Guide shafts penetrating the support rod are fixedly connected to both the left and right sides of the bottom end of the fixed rod, and the guide shafts contact the support rod. Distance sensors are uniformly distributed and fixedly connected to the bottom end of the support rod. A controller is fixedly connected to the left side of the front end of the truck body.

[0006] As a further improvement of this utility model, a stop switch is fixedly connected to one end of the outer side of the slider, and the stop switch is in contact with the fixed rod.

[0007] As a further improvement of this utility model, the top inner side of the support rod is fixedly connected with evenly distributed electric push rods, and the bottom outer side of the electric push rod is provided with a support block, and the support block is in contact with the support rod.

[0008] As a further improvement of this utility model, a pressure block is fixedly connected to the bottom end of the electric push rod, and the pressure block is in contact with the support block. A pressure sensor is fixedly connected to the bottom end of the pressure block, and the pressure sensor is in contact with the support block.

[0009] As a further improvement of this utility model, both the left and right ends of the inner side of the fixing rod are in contact with the fixing sleeves that are fixedly connected to the carriage. A spring is fixedly connected to the inner side of the fixing sleeve, and a locking block that penetrates the fixing sleeve is fixedly connected to the other end of the spring. The locking block is in contact with the fixing sleeve, and a locking plate that is in contact with the fixing rod is engaged on the outer side of the locking block.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. A dump truck frame, comprising a threaded shaft, a rotating rod, a support rod, an electric push rod, and a support block, wherein during cargo loading, a dual-axis motor is first controlled to drive the threaded shaft to connect with a slider in a spiral manner. Further, during the rotation of the rotating rod, the support rod is brought into contact with the ground under the sensing of a distance sensor. Then, during the extension of the electric push rod, the support block is brought into contact with the ground, while simultaneously the pressure block continuously presses against a pressure sensor. When the pressure value sensed by the pressure sensor reaches a set range, the electric push rod stops. At this point, the truck body is stably supported on the ground, effectively dispersing the impact force generated during cargo loading, reducing the impact on vehicle chassis and other components, extending vehicle service life, and reducing maintenance costs.

[0012] 2. A dump truck frame, comprising a fixed sleeve, a spring, a locking block, and a locking plate, wherein a fixed rod is fitted onto the outside of the fixed sleeve, and then the locking block is pressed to compress the spring and retract into the fixed sleeve. Then, by releasing the pressure on the locking block, the locking block is reset and locked together with the locking plate rotating on the outside of the truck body. This facilitates the installation of the auxiliary support mechanism of the truck body on the outside of the truck body and is simple and convenient to operate. Attached Figure Description

[0019] Example 1

[0020] like Figure 1-3 As shown, a dump truck frame includes a truck body 1. Fixed rods 2 are attached to both the front and rear ends of the truck body 1. A dual-axis motor 3 is fixedly connected to the center of the inner side of each fixed rod 2. A threaded shaft 4 is fixedly connected to the end of the main shaft of the dual-axis motor 3, and the threaded shaft 4 is rotatably connected to the fixed rod 2. A slider 5, which is slidably connected to the fixed rod 2, is helically connected to the outer side of the threaded shaft 4. A rotating rod 6 is rotatably connected to the bottom end of the slider 5 via a rotating shaft. A support rod 7, which contacts the truck body 1, is rotatably connected to the other end of the rotating rod 6 via a rotating shaft. Guide shafts 9, which pass through the support rod 7, are fixedly connected to both the left and right sides of the bottom end of the fixed rod 2, and the guide shafts 9 are in contact with the support rod 7. Distance sensors 10, evenly distributed, are fixedly connected to the bottom end of the support rod 7. A controller 19 is fixedly connected to the left front end of the truck body 1.

[0021] Example 2

[0022] like Figure 2 As shown, in order to solve the problem that it is not convenient to automatically control the dual-axis motor 3 to stop after the device is reset when the device is in use and the dual-axis motor 3 is reversed, a stop switch 8 is fixedly connected to one end of the outer side of the slider 5, and the stop switch 8 is in contact with the fixed rod 2. When the device is in use and the dual-axis motor 3 is reversed, the slider 5 triggers the stop switch 8 after the device is reset, which facilitates the automatic control of the dual-axis motor 3 to stop after the device is reset.

[0023] Example 3

[0024] like Figure 2As shown, in order to solve the problem of poor stability of the device under auxiliary support when the ground is uneven, the top inner side of the support rod 7 is fixedly connected with evenly distributed electric push rods 11, and the bottom outer side of the electric push rod 11 is provided with a support block 12, and the support block 12 is in contact with the support rod 7. After the support rod 7 is controlled to contact the ground, the evenly distributed electric push rods 11 are further extended by continuing to control them, so that the evenly distributed support block 12 is further in contact with the ground. When the ground is uneven, the stability of the device under auxiliary support is better.

[0025] Example 4

[0026] like Figure 2 As shown, in order to solve the problem that it is not easy to automatically control the electric push rod 11 to stop after the tightness of the contact between the support block 12 and the ground is met, a pressure block 13 is fixedly connected to the bottom end of the electric push rod 11, and the pressure block 13 is in contact with the support block 12. A pressure sensor 14 is fixedly connected to the bottom end of the pressure block 13, and the pressure sensor 14 is in contact with the support block 12. During the process of controlling the contact between the support block 12 and the ground, the pressure sensor 14 is continuously pressed by the pressure block 13 at the same time. When the pressure value sensed by the pressure sensor 14 reaches the set range and meets the tightness requirement of the contact between the support block 12 and the ground, it is convenient to automatically control the electric push rod 11 to stop.

[0027] Example 5

[0028] like Figure 1-3 As shown, to solve the problem of inconvenience in installing the auxiliary support mechanism of the carriage on the outside of the carriage 1, both ends of the inner side of the fixing rod 2 are in contact with the fixing sleeve 15 which is fixedly connected to the carriage 1. A spring 16 is fixedly connected to the inner side of the fixing sleeve 15. The other end of the spring 16 is fixedly connected to a locking block 17 that passes through the fixing sleeve 15 and is in contact with the fixing sleeve 15. A locking plate 18 that is in contact with the fixing rod 2 is engaged on the outer side of the locking block 17. The locking plate 18 is rotatably connected to the carriage 1 through a rotating shaft. By putting the fixing rod 2 on the outside of the fixing sleeve 15, and then pressing the locking block 17 to compress the spring 16 and retract it into the fixing sleeve 15, and then releasing the pressing of the locking block 17 to reset it and lock it together with the locking plate 18 that rotates on the outside of the carriage 1, it is convenient to install the auxiliary support mechanism of the carriage on the outside of the carriage 1.

[0029] In this embodiment, all electrical appliances in the device are powered by the vehicle's power supply. When loading cargo using the device, the fixing rod 2 is placed on the outside of the fixing sleeve 15, and then the locking block 17 is pressed to compress the spring 16 and retract it into the fixing sleeve 15. Then, by releasing the pressure on the locking block 17, the locking block 17 is reset and locked together with the rotating locking plate 18 on the outside of the carriage 1. At this time, the auxiliary support mechanism of the carriage can be installed on the outside of the carriage 1. After the installation is completed, the sensing range of the distance sensor 10 and the pressure sensor 14 is set by the controller 19. After the setting is completed, the dual-axis motor 3 is controlled by the controller 19 to drive the threaded shaft 4. The slider 5 is spirally connected, and the support rod 7 is brought into contact with the ground under the guidance of the guide shaft 9 during the rotation of the control rotating rod 6. When the distance value sensed by the distance sensor 10 reaches the set range, the controller 19 automatically controls the electric push rod 11 to extend, further controlling the support block 12 to contact the ground. At this time, the pressure block 13 will also continuously press the pressure sensor 14. When the pressure value sensed by the pressure sensor 14 reaches the set range and the electric push rod 11 stops, the carriage 1 is stably supported on the ground. In this way, the impact force generated during cargo loading can be effectively dispersed.
