Description

Technical Field

[0001] This application relates to the field of garbage truck technology, specifically a hook arm mechanism for a detachable garbage truck compartment. Background Technology

[0002] A detachable garbage truck compartment is a vehicle specifically designed for garbage collection and transportation, where the compartment can be easily separated from and connected to the chassis. This design makes garbage trucks more flexible and efficient in handling garbage.

[0003] The detachable garbage truck body and the tractor unit are connected by a hook-arm mechanism. Currently, most hook-arm mechanisms use a single hook arm to lift and hook the garbage truck body using a hydraulic cylinder for detachable connection. Therefore, during use, it is necessary to strictly control the alignment of the hook-arm mechanism with the lifting ring of the garbage truck body to prevent the garbage truck body from shifting during rotation and lifting. Thus, the placement of the garbage truck body relative to the tractor unit needs to be planned in advance when the hook-arm lifts the body, increasing the complexity of use. To address this issue, a hook-arm mechanism for detachable garbage truck bodies is proposed to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a hook arm mechanism for detachable garbage truck compartments, which has advantages such as automatic centering and leveling of double hook arms and improved ease of use.

[0005] To achieve the above objectives, this application provides the following technical solution: a hook-arm mechanism for a detachable garbage truck body, comprising a frame, a mounting seat fixedly mounted on the frame, and a main arm rotatably connected to the mounting seat via bearings. A hydraulic drive component is also rotatably mounted on the frame, and the power end of the hydraulic drive component is rotatably connected to the main arm. A lifting column is also slidably connected to the upper end of the main arm via a hydraulic cylinder. A centering arm is fixedly connected to the top of the lifting column. A hook for connecting the truck body lifting ring is provided on the centering arm. A centering structure for adjusting the position of the hook is provided inside the centering arm.

[0006] The centering structure includes a slider slidably installed inside the centering arm, a lead screw rotatably installed inside the centering arm, and a lead screw motor located on the side of the centering arm. The output end of the lead screw motor is fixedly connected to the lead screw, and the slider is threadedly connected to the lead screw.

[0007] Furthermore, a hook arm is slidably connected to the end of the main arm via a hydraulic cylinder, and the hook arm is L-shaped and connected to the main arm.

[0008] Furthermore, the lifting column and the centering arm are connected in a T-shape, and the connection position between the centering arm and the lifting column is located in the middle of the centering arm.

[0009] Furthermore, an extension rod is fixedly installed on the top of the slider, and a groove is provided on the top of the centering arm. The extension rod is slidably connected to the groove, and the width of the groove is smaller than the width of the slider.

[0010] Furthermore, a stabilizing frame is fixedly installed at the middle position of the centering arm, and the lead screw is rotatably connected to the stabilizing frame.

[0011] Furthermore, the lead screw includes two leads, the stabilizer includes two stabilizers, the two lead screws are respectively connected to the two stabilizers, and a transmission bearing is connected between the two stabilizers.

[0012] Furthermore, the transmission bearing includes a bearing sleeve, a main gear and a secondary gear rotatably mounted inside the bearing sleeve, the secondary gears being symmetrically arranged on both sides of the bearing sleeve, and the two secondary gears simultaneously meshing with the teeth of the main gear on both sides.

[0013] Furthermore, a positioning seat for positioning the carriage is fixedly installed on the side of the frame, and a roller is rotatably installed on the top of the frame via a bearing. A reinforcing rod is also fixedly installed at the end of the mounting seat via a bracket, and high-strength contact wheels are rotatably installed at both ends of the reinforcing rod.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The hook arm mechanism for detachable garbage truck bodies features a hook arm extending from the end of the main arm and two extension rods and hooks sliding on the centering arm. These extension rods are connected to a slider via a screw, allowing for centering adjustment of the two extension rods. This enables the two hooks to be adjusted to be relatively far apart when the hooks are pre-attached to the lifting ring of the garbage truck body, until both hooks are in contact with both ends of the lifting ring. At this point, the main arm can be positioned in the middle of the lifting ring, eliminating the need for pre-alignment of the truck body and improving ease of use. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figures 1 to 4 The hook arm mechanism for a detachable garbage truck body in this embodiment includes a frame 1, a mounting seat 2 fixedly mounted on the frame 1, and a main arm 3 rotatably connected to the mounting seat 2 via bearings. A hydraulic drive component 15 is also rotatably mounted on the frame 1. The power end of the hydraulic drive component 15 is rotatably connected to the main arm 3. Specifically, the end of the main arm 3 is slidably connected to a hook arm 4 via a hydraulic cylinder. The hook arm 4 is L-shaped and connected to the main arm 3.

[0023] Furthermore, the upper end of the main boom 3 is also slidably connected to the lifting column 5 via a hydraulic cylinder. The top of the lifting column 5 is fixedly connected to the centering arm 6. The centering arm 6 is equipped with a hook 9 for connecting the carriage lifting ring. The centering arm 6 is equipped with a centering structure for adjusting the position of the hook 9.

[0024] Preferably, the lifting column 5 and the centering arm 6 are connected in a T-shape, and the connection position between the centering arm 6 and the lifting column 5 is located in the middle of the centering arm 6.

[0025] In this embodiment, the centering structure includes a slider 7 slidably installed inside the centering arm 6, a lead screw 12 rotatably installed inside the centering arm 6, and a lead screw motor 11 located on the side of the centering arm 6. The output end of the lead screw motor 11 is fixedly connected to the lead screw 12, and the slider 7 is threadedly connected to the lead screw 12. The lead screw motor 11 drives the lead screw 12 to rotate, thereby adjusting the position of the slider 7 inside the centering arm 6 through the threaded engagement between the lead screw 12 and the slider 7.

[0026] It should be noted that an extension rod 8 is fixedly installed on the top of the slider 7, and a groove 10 is provided on the top of the middle arm 6. The extension rod 8 is slidably connected to the groove 10. The width of the groove 10 is smaller than the width of the slider 7, which can restrict the slider 7 and thus improve the connection stability of the slider 7.

[0027] Preferably, a stabilizer 13 is fixedly installed at the middle position of the middle arm 6, and the lead screw 12 is rotatably connected to the stabilizer 13, which can improve the rotational stability of the lead screw 12.

[0028] In this embodiment, there are two lead screws 12 and two stabilizers 13. The two lead screws 12 are connected to the two stabilizers 13 respectively, and a transmission bearing 14 is connected between the two stabilizers 13.

[0029] Specifically, the transmission bearing 14 includes a bearing sleeve 141, a main gear 142 and a secondary gear 143 rotatably mounted inside the bearing sleeve 141. The secondary gears 143 are symmetrically arranged on both sides of the bearing sleeve 141. The two secondary gears 143 simultaneously mesh with the teeth of the main gear 142 on both sides, and are driven by the main gear 142, so that the two lead screws 12 at both ends of the transmission bearing 14 can rotate in opposite directions.

[0030] In this embodiment, a positioning seat 17 for positioning the carriage is also fixedly installed on the side of the frame 1, and a roller 16 is rotatably installed on the top of the frame 1 through a bearing to facilitate the movement of the carriage on the frame 1.

[0031] Preferably, a reinforcing rod 18 is also fixedly installed at the end of the mounting base 2 by a bracket, and high-strength contact wheels 19 are rotatably installed at both ends of the reinforcing rod 18 to assist in contacting the bottom of the carriage during the lifting process.

[0032] The working principle of the above embodiments is as follows:

[0033] By controlling the hydraulic cylinder to retract the hook arm 4 relative to the main arm 3, and then controlling the hydraulic drive component 15 to rotate and lower the main arm 3 relative to the mounting base 2 to a suitable height position, the hook 9 on the hook arm 4 can face the detachable car body lifting ring, and the hook 9 is moved and fastened to the car body lifting ring. Then, by controlling the lead screw motor 11, the lead screw motor 11 drives the lead screw 12 fixedly connected to the power end to rotate. The lead screw 12 is threaded relative to the slider 7 under rotation, so that the slider 7 slides and changes position relative to the centering arm 6. At the same time, due to the transmission bearing 14 driving the two lead screws 12, the two sliders 7 can gradually move away from each other to the sides. During the sliding of the slider 7, the extension rod 8 and hook 9 on the slider 7 expand outward to the sides until they slide to the two ends of the detachable car body lifting ring, thereby achieving the centering of the hook 9 relative to the lifting ring, without the need to control the centering position between the car body and the car head in advance.
