Description

Technical Field

[0001] This utility model relates to the field of garbage crane technology, and in particular to a garbage crane drum jumper detection component. Background Technology

[0002] In the waste management industry, the garbage grab system is a key piece of equipment, undertaking important tasks such as garbage handling, mixing, and feeding. Its core component, the reel mechanism, is responsible for winding and unwinding the wire rope to precisely control the lifting and movement of the garbage grab. However, in practical applications, the arrangement of the wire rope on the reel becomes a significant factor affecting the system's stability and safety.

[0003] "Skipping" refers to the phenomenon where the wire rope deviates from its intended path on the drum, jumping out of its normal winding position; while "stacked lines" refers to the excessive accumulation of wire rope in localized areas of the drum, forming uneven layers. Both situations can severely impact the normal operation of a garbage crane system. However, most garbage crane systems on the market currently lack real-time monitoring and early warning mechanisms for skipped and stacked lines. Once these occur, they often require manual inspection to detect, making timely intervention difficult and increasing equipment failure rates and maintenance costs.

[0004] Traditional garbage truck reel designs rely heavily on mechanical cable management structures or manual adjustments to maintain the order of the steel cables. However, under high-speed, heavy-load, or frequent start-stop conditions, the steel cables are prone to shifting due to inertia or tension fluctuations. Existing technologies lack active restraint mechanisms and cannot fundamentally prevent the disorderly winding of steel cables on the reel surface, leading to accelerated cable wear, shortened service life, and even potentially serious accidents such as cable breakage.

[0005] To simplify cable management, some systems employ a single-layer winding design. However, this approach imposes strict limitations on drum size and lifting height. When long strokes or high load-bearing capacity are required, single-layer winding cannot meet the demands. Forcing the use of a single-layer structure can lead to excessively large drums, increased costs, or force the system to reduce operational efficiency. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a garbage crane drum jumper detection component. This design effectively solves the problems of conventional detection components lacking a steel cable arrangement constraint mechanism, steel cables being prone to disorderly winding under high-speed and heavy-load conditions, which aggravates wear and even breakage, single-layer winding design being limited by physical limitations and making it difficult to meet the needs of large stroke, high load and compact structure, and the detection of jumpers and stacked wires being lagging behind, relying on manual inspection and unable to provide real-time early warning.

[0007] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a track, a crane is provided at the top of the track, a winch motor is provided in the middle of the crane, a reducer is provided on the outside of the winch motor, the bottom of the reducer is connected to the crane, a drum is provided at the other end of the reducer, the drum is rotatably connected to the crane, a steel cable is wound on the outside of the drum, and a hydraulic claw is provided at the bottom of the steel cable; The overhead crane has a support on one side of its middle section. The support has a crossbar at its top and a swing rod at its top. The swing rod is rotatably connected to the support. The swing rod has a detection component inside and a pressure rod inside. The pressure rod has an adjustment component inside and a retaining ring at its bottom. The retaining ring cooperates with the steel cable.

[0008] Preferably, the detection assembly includes a first screw and a second screw, the tops of the first screw and the second screw are threadedly connected to the swing rod, and the bottom of the first screw abuts against the crossbar.

[0009] Preferably, a detector is provided at the bottom of the second screw, and the bottom of the detector is connected to the crossbar.

[0010] Preferably, the adjustment component includes a servo motor, the inner side of which is connected to the pressure rod.

[0011] Preferably, the servo motor has a reciprocating lead screw on its inner side and a limiting block on its outer side. The outer side of the limiting block is slidably connected to the pressure rod, and the bottom of the limiting block is connected to a retaining ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This equipment combines mechanical linkage with electronic detection to construct a jumper identification system, significantly improving operational safety and compatibility. When a steel cable jumps, the change in impact force on the shackle causes the swing arm to rise instantaneously. The second screw then drives the detector probe to extend and triggers a stop signal, effectively preventing the risk of the steel cable detaching and breaking. Simultaneously, the first screw can adjust the initial angle of the swing arm via its thread, allowing the equipment to adapt to steel cables of different diameters and reducing the types of spare parts required. The automatic stop and reverse mechanism reduces the annual damage rate of steel cables, ensuring the safety of personnel and equipment.

[0013] The adjustment assembly employs an innovative design with a servo motor-driven reciprocating screw. Through the coordinated movement of the limit block and the semi-circular retaining ring, it achieves multi-layer uniform winding of the steel cable. When the drum winds up or unwinds the steel cable, the servo motor drives the limit block to move horizontally back and forth, causing the retaining ring to guide the steel cable to form a spiral stack along the drum's axis. This effectively extends the stroke of a single drum, perfectly adapting to large-span scenarios such as deep pit waste disposal. By adjusting the servo motor speed, the spacing between each layer of steel cable can be precisely controlled, avoiding interlayer interference. It also supports rapid switching between single-layer and multi-layer modes to meet different material handling needs, significantly enhancing market adaptability. Attached Figure Description

Detailed Implementation

[0021] The following is in conjunction with the appendix Figures 1-6 The specific embodiments of this utility model will be described in further detail.

[0022] This utility model includes a track 101, with a crane 102 mounted on top of the track 101. The crane 102, which can move longitudinally along the track 101, is mounted on the horizontally laid track 101. The crane 102 serves as the main load-bearing and moving body of the entire equipment. It has a stable structure and multi-directional movement capability. A winch motor 104 is mounted in the middle of the crane 102 to provide driving force for the winding and unwinding of the steel cable. A reducer 105 is mounted on the outside of the winch motor 104. The reducer 105 converts the high-speed rotation of the motor into a low-speed, high-torque output through a precision gear transmission mechanism to meet the torque requirements when the steel cable lifts heavy objects. The bottom of the reducer 105 is connected to the overhead crane 102, and the bottom of the reducer 105 is firmly connected to the main body of the overhead crane 102 to ensure the stability of the overall structure. The other end of the reducer 105 is equipped with a drum 107, which is rotatably connected to the overhead crane 102. The drum 107 is rotatably connected to the overhead crane 102 through bearings and can rotate freely around its own axis. A steel cable is wound around the outside of the drum 107, and a hydraulic claw 103 is provided at the bottom of the steel cable. The outside of the drum 107 is wound with a high-strength steel cable. The steel cable adopts a multi-strand anti-rotation structure, which has excellent tensile strength and flexibility. The hydraulic claw 103 is controlled to open and close through a hydraulic system, which can realize the grabbing and release of materials such as garbage.

[0023] When garbage needs to be grabbed, the winch motor 104 starts, driving the drum 107 to rotate forward via the reducer 105. The steel cable is gradually released from the drum 107, and the hydraulic claw 103 descends above the garbage pile under its own weight and the traction of the steel cable. At this time, the hydraulic system drives the hydraulic claw 103 to close, firmly gripping the garbage. Subsequently, the winch motor 104 rotates in reverse, and the drum 107 begins to wind up the steel cable. The steel cable gradually winds around the drum 107, lifting the grabbed garbage to the designated height. Simultaneously, the overhead crane 102 can move laterally along the track 101, transporting the garbage to the target location. Upon reaching the destination, the hydraulic system activates again, the hydraulic claw 103 opens, and the garbage is released into the designated area. Throughout the process, the reducer 105 adjusts the speed and torque to ensure smooth cable winding and unwinding; the cooperation between the drum 107 and the steel cable achieves precise lifting and positioning of the heavy object. In addition, the equipment can be equipped with encoders, sensors, and other control components to monitor parameters such as cable tension and drum 107 speed in real time, ensuring safe and reliable operation.

[0024] A bracket 108 is provided on one side of the middle section of the overhead crane 102. The bracket 108 is fixed to the overhead crane 102. A crossbar 109 is provided at the top of the bracket 108 and is fixedly connected to the bracket 108. A swing rod 110 is provided at the top of the crossbar 109 and is rotatably connected to the bracket 108. When the swing rod 110 rotates, it will abut against the top of the fixed rod under the action of gravity. A detection component is provided inside the swing rod 110 to identify the rotation angle of the swing rod 110. A pressure rod 114 is provided inside the swing rod 110. The pressure rod 114 can abut against the top of the steel cable under the action of gravity. An adjustment component is provided inside the pressure rod 114. A retaining ring 202 is provided at the bottom of the adjustment component. The retaining ring 202 cooperates with the steel cable. When the drum 107 rotates, the retaining ring 202 inside the pressure rod 114 also begins to move horizontally back and forth, thereby completing the cable management and allowing for multi-layer stacking and winding, which can increase the hoisting stroke.

[0025] The detection assembly includes a first screw 111 and a second screw 112. The tops of the first screw 111 and the second screw 112 are threadedly connected to the swing rod 110. The bottom of the first screw 111 abuts against the crossbar 109. The first screw 111 and the second screw 112 can be rotated to adjust the elongation. Rotating the first screw 111 can adjust the initial angle of the swing rod 110, thereby adapting to steel cables of different diameters. A detector 113 is provided at the bottom of the second screw 112. The bottom of the detector 113 is connected to the crossbar 109. The detector 113 can monitor the movement of the second screw 112. When the second screw 112 moves upward as a whole, the probe of the detector 113 will extend accordingly, thereby identifying the tilt angle of the swing rod 110 from the side, thus determining the state of the swing rod 110. If the swing rod 110 suddenly rises and then falls, it indicates that a cable jump has occurred. At this time, the machine needs to be stopped, the drum 107 reverses, and the pressure rod 114 and other components are raised.

[0026] The adjustment assembly includes a servo motor 201, the inner side of which is connected to the pressure rod 114. A reciprocating screw 204 is provided on the inner side of the servo motor 201. The output shaft of the servo motor 201 extends into a transmission shaft. The reciprocating screw 204 is fixed on the inner side of the transmission shaft (i.e., the side closest to the motor body) by a key connection. A limit block 203 is provided on the outer side of the reciprocating screw 204. The limit block 203 has an internal threaded hole that matches the thread of the reciprocating screw 204. At the same time, a T-shaped slide groove is provided on its outer side. A T-shaped slide rail is welded to the corresponding position on the pressure rod 114. The two are slidably connected by the slide groove-slide rail structure. This design ensures that the limiting block 203 can move linearly along the axis of the reciprocating screw 204, while limiting its rotational freedom through the slide rail constraint to avoid motion interference. The outer side of the limiting block 203 is slidably connected to the pressure rod 114, and the bottom of the limiting block 203 is connected to the retaining ring 202. The retaining ring 202 is semi-circular and can guide the steel cable to complete single-layer and multi-layer uniform winding.

[0027] A crossbar 109 is fixed to the top of a support 108 on one side of the middle of the overhead crane 102. A swing rod 110 is rotatably connected to the crossbar 109. Under the action of gravity, the swing rod 110 naturally abuts against the top of the fixed rod. A pressure rod 114 is provided on its inner side, and the bottom of the pressure rod 114 contacts the steel cable through a retaining ring 202. When the steel cable is running normally, the pressure rod 114 swings slightly with the vibration of the steel cable, and the swing rod 110 maintains a stable tilt angle. If a cable jump occurs (the steel cable deviates from the track 101 of the drum 107), the impact force of the steel cable on the retaining ring 202 will suddenly change, causing the swing rod 110 to rise momentarily and then fall back.

[0028] The detection component's identification logic comprises a first screw 111, a second screw 112, and a detector 113: The first screw 111 adjusts the initial angle of the swing arm 110 via a threaded connection, accommodating steel cables of different diameters and ensuring an adjustable detection reference. The second screw 112 connects to the detector 113 at its bottom. When the swing arm 110 is raised due to a jumper wire, the second screw 112 moves upward, causing the detector 113 probe to extend and trigger a signal transmitted to the control system. Upon receiving the jumper wire signal, the system immediately stops and reverses the drum 107, simultaneously raising the pressure rod 114 to prevent further damage to the steel cable.

[0029] With dual protection of mechanical linkage and electronic detection, the jumper identification has low latency, significantly improving efficiency compared to traditional manual inspection. The first screw 111 adjustment function allows the equipment to be compatible with various steel cable specifications, reducing spare parts costs. The automatic stop and reverse mechanism effectively prevents accidents such as steel cable derailment and breakage, ensuring the safety of personnel and equipment.

[0030] The adjustment component is centered around a servo motor 201, which drives a limit block 203 to achieve horizontal reciprocating motion via a reciprocating screw 204. The output shaft of the servo motor 201 extends into a transmission shaft, which is keyed to the reciprocating screw 204 to provide precise power. A semi-circular retaining ring 202 is connected to the bottom of the limit block 203, which guides the steel cable to wind evenly as it reciprocates with the pressure rod 114.

[0031] When the drum 107 rotates to wind up and unwind the steel cable, the servo motor 201 drives the limit block 203 to move horizontally, causing the retaining ring 202 to cause the steel cable to oscillate periodically in the axial direction of the drum 107. This motion mode causes the steel cable to form multiple spiral layers on the drum 107. The spacing between each layer of steel cable can be controlled by adjusting the speed of the servo motor 201, thereby extending the winch stroke. The multi-layer winding increases the effective stroke of a single drum 107 by 2-3 times, making it suitable for deep pit waste disposal scenarios.
