Description

Technical Field

[0001] This utility model relates to the field of garbage truck technology, specifically to a loading and unloading device for a hook-lift garbage truck. Background Technology

[0002] Hook-lift garbage trucks, also known as detachable garbage trucks, are suitable for transporting domestic waste from residential communities and municipal sanitation. By compressing and crushing the garbage, their density is increased and their volume is reduced, greatly improving the efficiency of garbage collection and transportation. Garbage trucks usually use loading and unloading devices to facilitate garbage loading and unloading operations.

[0003] Referring to the patent document: Patent Publication No. CN213325002U, Patent Publication Date 2021-06-01, a novel hook-lift garbage truck loading and unloading device is disclosed, including a garbage truck body. The rear compartment of the garbage truck body is equipped with a tipping bucket for loading garbage. A sliding mechanism is provided at the rear end of the rear compartment of the garbage truck body. The bottom of the tipping bucket is slidably connected to the garbage truck body through the sliding mechanism. A groove is opened at the other end of the rear compartment of the garbage truck body. A driving mechanism is provided inside the groove. The driving mechanism is rotatably connected to the bottom of the tipping bucket. Through the design of the sliding mechanism, the tipping bucket can drive the first movable buckle and the slider to slide on the fixed rod under the push of the driving mechanism. This improves the tipping bucket's tilting stability and the connection stability between the tipping bucket and the garbage truck body, thus facilitating use.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Traditionally, when loading garbage containers onto the rear of a garbage truck using its boom lift, the hooks on the containers and boom lift often need to be precisely aligned. Traditional loading and unloading devices rely on manual operation experience and visual judgment. Drivers need to repeatedly adjust the vehicle position and boom lift angle to achieve precise hooking. This operation method not only consumes a lot of time, but also, in complex operating environments (such as narrow streets or nighttime operations), due to limited visibility or operational errors, it is very easy for the garbage containers to collide with and be damaged by the vehicle, or even cause safety accidents.

[0006] Therefore, this utility model provides a loading and unloading device for a hook-lift garbage truck. Summary of the Invention

[0007] To address the cumbersome and inconvenient process of connecting the hooks of the garbage container to the hooks of the hook-lift arm when loading garbage containers onto a hook-lift garbage truck, this utility model aims to provide a loading and unloading device for hook-lift garbage trucks.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a loading and unloading device for a hook-lift garbage truck, comprising a hook-lift garbage truck body, wherein an adjustment mechanism is provided on one side of the hook-lift garbage truck body for adjusting the angle position of the hook, the adjustment mechanism comprising:

[0009] The angle execution component includes an outer shell disposed on one side of the hooklift garbage truck body. A mounting bracket is fixedly installed on the lower inner surface of the outer shell. A worm gear is fixedly installed in the middle of the mounting bracket. A deflection bracket is slidably disposed on the upper part of the mounting bracket. A worm is rotatably mounted in the middle of the deflection bracket. A servo motor is fixedly installed on one side of the mounting bracket. One end of the worm is fixedly installed on the drive end of the servo motor. A driven bevel gear is rotatably mounted on the upper part of the deflection bracket. A hook is fixedly installed in the middle of the driven bevel gear. A drive component is disposed on one side of the driven bevel gear.

[0010] A horizontal actuator, located on one side of the housing, is used to adjust the horizontal position of the hook.

[0011] Preferably, the horizontal execution component includes a fixed frame detachably installed on one side of the hooklift garbage truck body, a limit rod fixedly installed in the middle of the fixed frame, a movable block slidably engaged on the outer surface of the limit rod, one side of the outer shell fixedly installed on one end of the movable block, a drive plate fixedly installed on one side of the movable block, an electric push rod fixedly installed on one side of the fixed frame, and a drive end of the electric push rod fixedly installed on one side of the fixed frame.

[0012] Preferably, the drive assembly includes a drive motor fixed to one side of the upper part of the deflection frame, an active bevel gear is provided on one side of the driven bevel gear, the active bevel gear and the driven bevel gear are meshed and connected to each other, and one end of the active bevel gear is fixedly installed on the drive end of the drive motor.

[0013] Preferably, the upper part of the outer shell is provided with a slot, and the lower part of the hook is slidably engaged in the middle of the slot.

[0014] Preferably, the lower part of the deflection frame is fixedly installed with a locking rod, and the upper part of the mounting frame has two symmetrically distributed limiting grooves. The two locking rods are slidably locked in the middle of the limiting grooves, and the lower part of the locking rods is in contact with the upper surface of the middle part of the mounting frame.

[0015] Preferably, a groove is provided on one side of the fixed frame, and one side of the drive plate is slidably engaged in the middle of the groove. Beneficial effects

[0016] This utility model provides a loading and unloading device for a hooklift garbage truck. Compared with the prior art, it has the following advantages:

[0017] 1. In this application, the servo motor drives the deflection frame to move along the upper surface of the mounting bracket on the arc-shaped surface through worm gear and worm wheel transmission, thereby adjusting the pitch angle of the hook. The drive motor drives the hook to rotate horizontally through the meshing of the active bevel gear and the driven bevel gear, so that the hook can quickly align with the hanging point on the container. This avoids the angle deviation between the hook and the upper lug of the container caused by environmental or operational issues, which could lead to collision damage. This improves docking efficiency, enabling rapid loading and unloading of the hook-lift garbage truck's container.

[0018] 2. This application allows the driver to send commands from the cab via a control lever, causing the electric actuator to drive the drive plate to move, which in turn causes the moving block to slide along the limit rod, allowing the hook to move flexibly in the horizontal direction to adapt to garbage containers of different sizes and parking positions. Even when the vehicle is not directly in front of the container, the hook can still be fixed to the pull lug. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a loading and unloading device for a hook-lift garbage truck, including a hook-lift garbage truck body 1, with an adjustment mechanism 2 provided on one side of the hook-lift garbage truck body 1. The adjustment mechanism 2 is mainly located at the end of the hook-lift device of the hook-lift garbage truck body 1, and is used to adjust the angle position of the hook 219. The adjustment mechanism 2 includes:

[0028] The angle execution component 21 includes an outer shell 211 disposed on one side of the hooklift garbage truck body 1. A mounting bracket 212 is fixedly installed on the lower inner surface of the outer shell 211. The outer shell 211 is welded from Q345B high-strength steel plate. The mounting bracket 212 is fixed to the lower inner surface by M16 high-strength bolts. The upper part of the mounting bracket 212 is arc-shaped, and the deflection direction of the deflection bracket 217 is along the arc surface at the top of the mounting bracket 212. A worm gear 213 is fixedly installed in the middle of the mounting bracket 212. The deflection bracket 217 is slidably disposed on the upper part of the mounting bracket 212. A worm gear 214 is rotatably installed in the middle of the deflection bracket 217. A servo motor 215 is fixedly installed on one side of the mounting bracket 212. The servo motor 215 is an AC servo motor and is driven by a dedicated servo motor. The device is connected to the motion controller in the cab. The control panel in the cab is equipped with a manual fine-tuning knob for controlling the servo motor 215. During the docking process of the garbage container, the system detects the relative position with the container in real time through a laser rangefinder installed on the hook 219, so as to control the servo motor 215 to automatically adjust the angle of the hook 219 according to the detection data to achieve precise docking. One end of the worm gear 214 is fixedly installed on the drive end of the servo motor 215. The upper part of the deflection frame 217 is rotatably mounted with a driven bevel gear 2182. The middle part of the driven bevel gear 2182 is fixedly mounted with a hook 219. The hook 219 is forged from alloy steel and the surface is carburized and quenched. The hook head is inlaid with a hard alloy block to enhance wear resistance. A drive component is provided on one side of the driven bevel gear 2182.

[0029] The horizontal actuator 22 is located on one side of the housing 211 and is used to adjust the horizontal position of the hook 219.

[0030] The horizontal execution component 22 includes a fixing frame 221 detachably mounted on one side of the hooklift garbage truck body 1. The fixing frame 221 is detachably mounted on the end of the hooklift device of the hooklift garbage truck body 1 by M20 bolts. A limit rod 222 is fixedly mounted in the middle of the fixing frame 221. A moving block 223 is slidably engaged on the outer surface of the limit rod 222. A chrome-plated limit rod 222 with a pentagonal cross-section is fixedly mounted on the limit rod 222 by positioning pins and bolts. The pentagonal structure allows the limit rod 222 to slide stably on its surface without deflection. One side of the outer shell 211 is fixedly mounted on one end of the moving block 223. A drive board 224 is fixedly mounted on one side of the moving block 223, and an electric push rod 225 is fixedly mounted on one side of the fixed frame 221. The electric push rod 225 is a servo electric push rod, with its housing made of high-strength aluminum alloy and hard anodized, achieving an IP67 protection rating. The electric push rod 225 is connected to the PLC control system in the cab via a CAN bus. During loading and unloading operations, the driver can select a preset loading and unloading mode via the touchscreen in the cab and send control commands to the electric push rod 225 via the driver's joystick. The drive end of the electric push rod 225 is fixedly mounted on one side of the fixed frame 221, and its drive board 224 is... Figure 6 It can be seen that its structure is L-shaped, and the middle of one side of the moving block 223 is installed on the end of the long side of the L-shaped structure of the drive plate 224 that is far away from the short side, while the driving end of the electric push rod 225 is installed on the short side of the L-shaped structure, thereby reducing the installation space of the electric push rod 225 while increasing the movement stroke of the moving block 223.

[0031] The drive assembly includes a drive motor 218 fixed on one side of the upper part of the deflection frame 217. The drive motor 218 is a permanent magnet synchronous servo motor. The drive motor 218 is connected to the main controller in the cab through a dedicated servo driver. A drive bevel gear 2181 is provided on one side of the driven bevel gear 2182. The drive bevel gear 2181 and the driven bevel gear 2182 are meshed with each other. One end of the drive bevel gear 2181 is fixedly installed on the drive end of the drive motor 218. Driven by the drive motor 218, the drive bevel gear 2181 is rotated, which in turn drives the driven bevel gear 2182 to rotate, thereby adjusting the horizontal angle position of the hook 219.

[0032] The upper part of the outer shell 211 is provided with a slot 2111, and the lower part of the hook 219 is slidably locked in the middle of the slot 2111. The slot 2111 is a rectangular slot with a width of 1.2 times the diameter of the hook 219, so that the hook 219 can be easily deflected under the drive of the servo motor 215.

[0033] A locking rod 2161 is fixedly installed on the lower part of the deflection frame 217. Two symmetrically distributed limiting grooves 216 are opened on the upper part of the mounting frame 212. The two locking rods 2161 are slidably locked in the middle of the limiting grooves 216, and the lower part of the locking rod 2161 is in contact with the upper surface of the middle part of the mounting frame 212. The locking rod 2161 is slidably locked in the limiting groove 216. At the same time, due to the contact with the upper surface of the middle part of the mounting frame 212, the deflection frame 217 is limited and fixed, ensuring that the deflection frame 217 can only move along the direction of the locking groove 2111 and cannot move up and down.

[0034] A groove 226 is provided on one side of the fixed frame 221, and the drive plate 224 is slidably locked in the middle of the groove 226. The groove 226 facilitates the connection and fixation between the moving block 223 and the drive plate 224, and also limits the movement of the moving block 223, making its movement more stable.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, when the container of the hooklift garbage truck body 1 is loaded onto the truck, the main arm and auxiliary arm, which are in a Z-shape structure, are driven forward by the hydraulic cylinder to bring the hook 219 and the pull lugs on the container closer to each other. At this time, the drive plate 224 is moved by the electric push rod 225, which in turn moves the moving block 223 along the limit rod 222. Through precision sliding, the hook 219 is aligned with the pull lugs on the container. The main arm and auxiliary arm, which are in a Z-shape structure, move forward under the drive of the hydraulic cylinder to bring the hook 219 closer to the pull lugs on the container.

[0037] At this time, the drive motor 218 can be started to drive the active bevel gear 2181 to rotate, which in turn drives the driven bevel gear 2182 to rotate, thereby causing the hook 219 to rotate so that it is perpendicular to the pull lugs set parallel to the box.

[0038] The servo motor 215 drives the worm gear 214 to rotate, and the meshing of the worm wheel 213 and the worm gear 214 causes the deflection frame 217 to deflect, thereby adjusting the angle of the hook 219 so that the end of the hook 219 extends into the center of the pull lug. This ensures that when the main arm and auxiliary arm move in a Z-shaped structure under the drive of the hydraulic cylinder, the hook 219 can be smoothly engaged in the middle of the pull lug. When the hook-lift garbage truck body pulls the container along a straight line, the drive motor 218, the servo motor 215 and the electric push rod 225 adjust the container to be aligned with the vehicle body, and then the container can be pulled to move and be loaded onto the truck.
