Description

Technical Field

[0001] This utility model relates to the field of engineering machinery and equipment technology, and in particular to a hydraulic automatic leveling trolley for a ladder truck. Background Technology

[0002] The aerial ladder material transport vehicle is a specialized operation vehicle that uses a vehicle-mounted aerial ladder to transport materials upstairs. It is suitable for high-altitude operations in building complexes in cities of all sizes. It features easy operation and learning, high flexibility, wide application, high work efficiency, and excellent performance. It can be used for high-altitude fire fighting, high-altitude rescue, exterior high-altitude cleaning, furniture moving in high-rise buildings, high-altitude emergency repairs, high-altitude equipment installation, and other high-altitude operations.

[0003] The existing ladder truck material transport trolley requires manual adjustment of the trolley angle during use, which is time-consuming and inefficient. Furthermore, manual adjustment is cumbersome and increases labor costs. Therefore, a hydraulic automatic leveling trolley for the ladder truck is provided. Summary of the Invention

[0004] In view of this, the present invention provides a hydraulic automatic leveling trolley for a ladder truck, and the main technical problem to be solved is: the problem of the ladder material transport trolley needing to be manually leveled during use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hydraulic automatic leveling trolley for a ladder truck, comprising a base, a moving device fixedly connected to the lower part of the base, a ladder movably connected to the inner side of the moving device, a motor fixedly connected to the left side of the base, a hopper movably connected to the upper part inside the base, and a hydraulic telescopic rod movably connected between the base and the hopper. The hydraulic telescopic rod includes a hydraulic cylinder movably connected to the upper outer side of the base and a hydraulic column to the lower outer side of the hopper. Both the hydraulic cylinder and the hydraulic column have through holes inside, and the hydraulic cylinder and the hydraulic column are movably connected.

[0006] By adopting the above technical solution, the hydraulic column is controlled to extend from the inside of the hydraulic cylinder, allowing the hydraulic telescopic rod to rotate on the outside of the connecting shaft and the connecting column. This, in turn, pushes the hopper so that the fixed column can rotate inside the connecting plate. Through rotation, the hopper body can be adjusted to a horizontal position.

[0007] As a further description of the above technical solution: the base includes a seat body, the top of the seat body is provided with a sliding groove, a connecting plate is fixedly connected to the left side of the top of the seat body, the connecting plate is provided with a rotating hole, a control box is fixedly connected to the middle of the top of the seat body, a slider is movably connected to the inside of the seat body, and a connecting column is fixedly connected to the inner side of the slider.

[0008] By adopting the above technical solution, the control box is used to control the operation of the device. The control box is electrically connected to the tilt sensor, and the inside of the control box is equipped with a receiver to receive the tilt sensor signal. When the control box receives the signal transmitted back by the tilt sensor, it can control the motor device and the hydraulic telescopic rod to run until the tilt sensor detects that the hopper is in a horizontal state and then stops running.

[0009] As a further description of the above technical solution: the hopper includes a fixed column movably connected inside the connecting plate, with rotating plates fixedly connected to both ends of the fixed column, a hopper body fixedly connected to the top of the rotating plate, an inclination sensor fixedly connected to the middle of the lower part of the hopper body, a support column fixedly connected to the right side of the lower part of the hopper body, and a connecting shaft fixedly connected between the support columns.

[0010] By adopting the above technical solution, the tilt sensor is used to detect whether the hopper is tilted. When it detects that the hopper is tilted, it can transmit a signal to the control box. When the lower part of the hopper is parallel to the base, the bottom of the support column contacts the base to support the hopper.

[0011] As a further description of the above technical solution: the motor device includes a motor body fixedly connected to the left side of the base, and a stud is fixedly connected to the output end of the motor body, and the stud is threadedly connected to the slider.

[0012] By adopting the above technical solution, starting the motor body enables the stud to rotate, and by rotating forward and reverse, the slider can move back and forth. By moving it to the right, the hydraulic telescopic rod can be driven to further adjust the angle of the hopper, ensuring a larger range of hopper angle adjustment, which facilitates leveling the hopper when the ladder is at various angles.

[0013] As a further description of the above technical solution: the ladder includes ladder arms movably connected to the inside of the mobile device, and connecting beams are fixedly connected between the ladder arms.

[0014] By adopting the above technical solution, the connecting beam is used to connect the ladder arms, ensuring that the ladder is more stable.

[0015] As a further description of the above technical solution: the moving device includes a fixed plate fixedly connected to the lower part of the seat, a fixed shaft fixedly connected to the inner side of the fixed plate, and a moving wheel movably connected to the outer side of the fixed shaft.

[0016] By adopting the above technical solution, the movable wheel can rotate on the outside of the fixed shaft, and the outside of the movable wheel is in contact with the ladder arm, enabling it to move on the ladder.

[0017] By employing the above technical solution, the hydraulic automatic leveling trolley for the ladder truck of this utility model has at least the following beneficial effects:

[0018] Compared with existing technologies, this hydraulic automatic leveling trolley for a ladder truck, equipped with a base, hydraulic telescopic rod, and motor, facilitates automatic leveling of the hopper. During operation, when the tilt sensor detects that the hopper is tilted, it transmits a signal to the control box. The control box controls the hydraulic column to extend from inside the hydraulic cylinder, allowing the hydraulic telescopic rod to rotate outside the connecting shaft and connecting column. This, in turn, pushes the hopper, causing the fixed column to rotate inside the connecting plate. This rotation adjusts the hopper to a horizontal position. When the hydraulic telescopic rod is fully extended and the hopper is still tilted, the control box controls the motor to rotate the stud. This rotation moves the slider to the right, further adjusting the angle of the hopper with the hydraulic telescopic rod. This ensures a wider range of hopper angle adjustment, facilitating leveling of the hopper at various ladder angles. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0025] Reference Figure 1-4 This utility model provides a hydraulic automatic leveling trolley for a ladder truck, including a base 1. A moving device 6 is fixedly connected to the lower part of the base 1, and a ladder 5 is movably connected to the inner side of the moving device 6. A motor device 4 is fixedly connected to the left side of the base 1. A hopper 3 is movably connected to the upper part of the interior of the base 1. A hydraulic telescopic rod 2 is movably connected between the base 1 and the hopper 3. The hydraulic telescopic rod 2 includes a hydraulic cylinder 201 movably connected to the upper outer side of the base 1 and a hydraulic column 202 movably connected to the lower outer side of the hopper 3. Both the hydraulic cylinder 201 and the hydraulic column 202 have through holes 203 inside. The through hole 203 inside the 02 is used for rotation on the outside of the connecting shaft 306, and the through hole 203 inside the hydraulic cylinder 201 is used for rotation on the outside of the connecting column 106. The hydraulic cylinder 201 is movably connected to the hydraulic column 202. By controlling the hydraulic column 202, it can extend out from the inside of the hydraulic cylinder 201, so that the hydraulic telescopic rod 2 can rotate on the outside of the connecting shaft 306 and the connecting column 106, thereby pushing the hopper 3 so that the fixed column 303 can rotate inside the connecting plate 103. By rotating, the hopper 301 can be adjusted to a horizontal position.

[0026] Furthermore, the base 1 includes a seat body 101, the top of which is provided with a slide groove 102 for the movement of the slider 107. A connecting plate 103 is fixedly connected to the left side of the top of the seat body 101. The connecting plate 103 has a rotating hole 104 inside for the rotation of the fixed column 303. A control box 105 is fixedly connected to the middle of the top of the seat body 101. The control box 105 is used to control the operation of the device. The control box 105 is electrically connected to the tilt sensor 304, and the inside of the control box 105 is provided with a receiver for receiving the signal from the tilt sensor 304. When the control box 105 receives the signal transmitted back by the tilt sensor 304, it can control the motor device 4 and the hydraulic telescopic rod 2 to run until the tilt sensor 304 detects that the hopper 3 is in a horizontal state and then stops running. A slider 107 is movably connected inside the seat body 101. A connecting column 106 is fixedly connected to the inner side of the slider 107, and the slider 107 can move inside the seat body 101.

[0027] Furthermore, the hopper 3 includes a fixed column 303 movably connected inside the connecting plate 103. A rotating plate 302 is fixedly connected to both ends of the fixed column 303. A hopper body 301 is fixedly connected to the top of the rotating plate 302. An inclination sensor 304 is fixedly connected to the middle of the lower part of the hopper body 301. The inclination sensor 304 is used to detect whether the hopper 3 is in an inclined state. When it detects that the hopper body 301 is in an inclined state, it can transmit a signal to the control box 105. A support column 305 is fixedly connected to the right side of the lower part of the hopper body 301. A connecting shaft 306 is fixedly connected between the support columns 305. When the lower part of the hopper 3 is parallel to the base 1, the bottom of the support column 305 contacts the base 1 to support the hopper body 301.

[0028] Furthermore, the motor device 4 includes a motor body 401 fixedly connected to the left side of the base 101. A stud 402 is fixedly connected to the output end of the motor body 401. The stud 402 is threadedly connected to the slider 107. By starting the motor body 401, the stud 402 can rotate. By rotating forward and backward, the slider 107 can move back and forth. By moving it to the right, the hydraulic telescopic rod 2 can be driven to further adjust the angle of the hopper 3, ensuring a larger range of angle adjustment for the hopper 3, which is convenient for leveling the hopper 3 when the ladder 5 is at various angles.

[0029] Furthermore, the ladder 5 includes ladder arms 501 movably connected to the inside of the mobile device 6, and connecting beams 502 are fixedly connected between the ladder arms 501. The connecting beams 502 are used to connect the ladder arms 501 to ensure that the ladder 5 is more stable.

[0030] Furthermore, the moving device 6 includes a fixed plate 601 fixedly connected to the lower part of the base 101. A fixed shaft 602 is fixedly connected to the inner side of the fixed plate 601, and a moving wheel 603 is movably connected to the outer side of the fixed shaft 602. The moving wheel 603 can rotate on the outer side of the fixed shaft 602, and the outer side of the moving wheel 603 is in contact with the ladder arm 501, so that it can move on the ladder 5.

[0031] Working principle: When the tilt sensor 304 detects that the bucket 301 is tilted, it transmits a signal to the control box 105. The control box 105 controls the hydraulic column 202 to extend from the inside of the hydraulic cylinder 201, allowing the hydraulic telescopic rod 2 to rotate outside the connecting shaft 306 and the connecting column 106. This, in turn, pushes the hopper 3, causing the fixed column 303 to rotate inside the connecting plate 103. Through rotation, the bucket 301 can be adjusted to a horizontal position. When the hydraulic telescopic rod 2 is fully extended and the hopper 3 is still tilted, the control box 105 controls the motor body 401 to rotate the stud 402. Through rotation, the slider 107 moves to the right, thereby driving the hydraulic telescopic rod 2 to further adjust the angle of the hopper 3, ensuring a wider range of angle adjustment for the hopper 3, making it easier to level the hopper 3 when the ladder 5 is at various angles.
