Description

Technical Field

[0001] This utility model belongs to the field of vehicle-mounted lifting technology, and specifically relates to a vehicle-mounted lightweight garbage lifting device. Background Technology

[0002] In the narrow alleys of the old city, large garbage trucks cannot enter, and small garbage trucks with a load capacity of 3-5 tons must be relied upon. To meet the vehicle load-bearing restrictions, traditional devices achieve lightweighting by using thin-walled steel or ordinary aluminum alloys. However, this type of design significantly weakens the rigidity of the clamping structure. When clamping a full bin of garbage, the unidirectional planar gripper is prone to deformation, which can cause the clamping force to decrease by more than 30%. This can easily lead to the garbage bin slipping off one side during the clamping process. This pursuit of lightweighting to adapt to small vehicles inevitably results in insufficient strength of the clamping structure. Utility Model Content

[0003] This utility model addresses the problems of existing technologies by providing a lightweight vehicle-mounted garbage lifting device, the specific technical solution of which is as follows: The vehicle-mounted lightweight garbage lifting device includes: The base is rotatably mounted on the garbage truck; Two sets of extension arms that can be slidably mounted on the base; A drive assembly for driving the two sets of the extension arms closer together or further apart; And two sets of clamping assemblies, each set of which is mounted on the distal end of the extension arm, for clamping the trash can when the two sets of extension arms come close to each other.

[0004] As a further technical solution of this utility model, the driving component includes: The drive motor is mounted on the base. The lead screw is rotatably mounted on the base and connected to the output end of the drive motor. The threads on both sides of the lead screw are in opposite directions, and two sets of extension arms are screwed onto both sides of the lead screw respectively.

[0005] As a further technical solution of this utility model, the clamping assembly includes: Positive clamp, rotatably mounted at the distal end of the extension arm; Two sets of side clamps are respectively rotatably set at both ends of the front clamp; And a drive cylinder, which is rotatably mounted between the back of the front clamping plate and the side clamping plate; After the positive clamping plate is attached to the trash can, the driving cylinder can drive the side clamping plates at both ends to rotate inward to form multi-directional clamping.

[0006] As a further technical solution of this utility model, a wire hole for the air supply pipe is provided inside the extension arm.

[0007] The beneficial effects of this utility model are as follows: The clamping assembly uses a combination of a "front clamping plate + side clamping plate + drive cylinder". The arc-shaped design of the front clamping plate fits the side wall of the trash can, and the side clamping plate rotates inward under the drive of the cylinder to form a "triangular support". It can be adapted to trash cans of different shapes such as round and square, solving the problems of "poor adaptability and easy fall-off" of traditional clamps. The ball joint connection between the front clamping plate and the extension arm allows for ±10° angle fine adjustment, adapting to deformable trash cans and further improving versatility.

[0010] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0011] Figure 1 A schematic diagram of the overall structure of the vehicle-mounted lightweight garbage lifting device is shown. Figure 2 A schematic diagram of the drive component 300 is shown; Figure 3 A schematic diagram of the clamping assembly 400 is shown; Figure 4 A schematic diagram of the extension arm 200 is shown.

[0012] Figure 1 The lightweight vehicle-mounted garbage lifting device includes: The base 100 is rotatably mounted on the garbage truck; in actual use, it can be rotated upwards to lift the garbage bin and rotated downwards to lower the garbage bin. Two sets of extension arms 200 that can be slidably mounted on the base 100; Drive assembly 300 is used to drive the two sets of extension arms 200 to move closer or further apart from each other; And two sets of clamping assemblies 400, which are respectively installed at the far end of the extension arm 200, for clamping the trash can when the two sets of extension arms 200 come close to each other.

[0013] The core load-bearing and rotation functions of the base: The base 100 is connected to the garbage truck frame through a rotating shaft and is driven by a hydraulic motor or servo motor to achieve ±90° rotation. An angle sensor is installed at the rotating shaft to provide real-time feedback on the rotation position and avoid structural collisions caused by excessive rotation. During upward rotation, the garbage bin is lifted and transferred to the garbage truck inlet via the extension arm 200 and clamping assembly 400; As you rotate downwards, place the empty trash can back on the ground.

[0014] Sliding and coordinated operation of the extension arms: The two sets of extension arms 200 are embedded in the slide rails of the base 100 via bottom sliders, and can slide horizontally along the base. When the drive assembly 300 is activated, the two sets of extension arms simultaneously move closer to or further away from the trash can to release it, adapting to trash cans of different sizes.

[0015] Targeted fixation of the clamping assembly: The clamping assembly 400 is installed at the far end of the extension arm and moves with the extension arm to achieve "encircling" positioning of the trash can - when the extension arm approaches the centering clamp 410 and fits against the side wall of the trash can, the side clamp 420 rotates inward to complete the clamping, ensuring that the trash can does not shake during the transfer process.

[0016] Figure 2 In the middle, the driver component 300 includes: The drive motor 310 is mounted on the base 100; The lead screw 320 is rotatably mounted on the base 100 and connected to the output end of the drive motor 310. The threads on both sides of the lead screw 320 are opposite in direction, and two sets of extension arms 200 are screwed onto both sides of the lead screw 320 respectively.

[0017] The drive motor 310 drives the lead screw to rotate. The threads on both sides of the lead screw are in opposite directions, i.e., the left side is right-handed and the right side is left-handed. The two sets of extension arms 200 are screwed to the lead screw through nut seats. When the lead screw rotates forward, the two sets of extension arms move towards the trash can synchronously along the slide rail to clamp it; when it rotates backward, they move away from each other synchronously to release, realizing "one-button opening and closing".

[0018] Figure 3 In the middle, the clamping assembly 400 includes: The positive clamp 410 is rotatably mounted at the distal end of the extension arm 200; Two sets of side clamps 420 are respectively rotatably set at both ends of the front clamp 410; And a drive cylinder 430, which is rotatably mounted between the back of the front clamping plate 410 and the side clamping plate 420; After the main clamping plate 410 is attached to the trash can, the drive cylinder 430 can drive the side clamping plates 420 at both ends to rotate inward to form multi-directional clamping.

[0019] The clamp plate 410 features a curved panel with an arc that matches the sidewalls of common trash cans. Rubber pads are affixed to the inside, providing initial fixation through friction when fitting the trash can and simultaneously cushioning impacts. The clamp plate and extension arm 200 are connected via a ball joint, allowing for fine-tuning to accommodate non-standard shaped trash cans.

[0020] The side clamps are internally rotated and clamped: the two sets of side clamps 420 are connected to the two ends of the main clamp 410 by pins and driven by the drive cylinder 430. When the cylinder piston rod extends, the side clamps rotate internally around the pins to form a "triangular support" from both sides of the garbage can.

[0021] Figure 4 In the middle, the extension arm 200 has a wire hole 210 for the air supply pipe to pass through.

[0022] The extension arm 200 has a wire hole 210 inside along its length for passing through the air pipe of the clamping assembly 400, namely the air source line of the drive cylinder 430 and the load cell cable. In actual use, the load cell is installed at the connection end between the extension arm 200 and the clamping assembly 400. Utilizing the force transmission characteristics of the connection end, the clamping force of the trash can can be directly applied to the sensor to realize the real-time acquisition of pressure signals. In actual use, the load cell communicates with the vehicle's central control system and can transmit the weighing data to the central control system in real time to facilitate weight monitoring.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
