Description

Technical Field

[0001] This utility model relates to the field of garbage hoisting technology, and in particular to a support bracket for garbage hoisting rolls. Background Technology

[0002] Garbage grabbers are core equipment in waste-to-energy plants and waste transfer stations, primarily used for handling, mixing, and feeding waste within waste pits. The garbage grabber (i.e., the garbage grab bucket), as its actuator, is characterized by its large weight, highly variable load capacity, and frequent operation.

[0003] Currently, common garbage reels are typically supported and moved by two parallel crossbeams. These two crossbeams are installed above the garbage pit, with their ends supported by end beams, while the middle of the crossbeams is suspended. The garbage reel moves back and forth on these crossbeams via a traveling mechanism to cover the entire working area of ​​the garbage pit.

[0004] However, the aforementioned existing technology has a significant drawback: the structural strength and stiffness of the crossbeam are insufficient, posing a safety hazard. Specifically, when the garbage hoist reaches the mid-span of the crossbeam, its entire weight (including the weight of the grab bucket and the full load of garbage) will be borne entirely by the middle of the crossbeam as a concentrated load. Since the crossbeam is only supported at both ends, the middle section will experience the greatest bending stress and deflection.

[0005] This structural design presents the following significant challenges: 1. The pressure resistance is severely tested: Under long-term and frequent cyclic loads, fatigue damage is likely to occur at the mid-span of the beam, reducing the service life of the equipment.

[0006] 2. High risk under extreme working conditions: When the amount of garbage being lifted is too large, i.e. when the lifting is overloaded, the bending moment acting on the middle of the crossbeam will increase sharply, which can easily cause plastic deformation of the crossbeam or even sudden breakage, causing the entire garbage crane system to be paralyzed, resulting in serious safety accidents and production interruptions.

[0007] 3. Limitations on performance improvement: Due to concerns about the load-bearing capacity of the crossbeams, it is often necessary to select steel sections with larger cross-sections or carry out special reinforcement during the design phase. This increases the manufacturing cost of the equipment and also limits the further improvement of the lifting capacity of the garbage roll.

[0008] Therefore, in order to solve the problems of weak support in the middle of the crossbeam and insufficient load-bearing capacity in the existing support structure, there is an urgent need for a new type of load-bearing bracket to enhance structural rigidity, distribute load, fundamentally eliminate the risk of crossbeam breakage, and ensure the safe, stable and efficient operation of the garbage crane equipment. Utility Model Content

[0009] In view of the above situation and to overcome the defects of the prior art, this utility model provides a support bracket for garbage rolls. This design effectively solves the problems of weak support in the middle of the crossbeam and insufficient pressure bearing capacity in the existing support structure.

[0010] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a crossbeam, on which a hanger is slidably connected, a lifting device is provided on the hanger, a wheel is fitted below the lifting device, a claw is rotatably connected to the wheel, a traction frame is fixedly connected to both ends of the crossbeam, a pulling assembly is provided on both sets of the traction frames, a support arm is fixedly connected to the pulling assembly, the support arm is fixedly connected to the hanger, a sliding groove is provided in the support arm, and the sliding groove is slidably connected to the crossbeam.

[0011] Preferably, the traction assembly includes an adjusting roller, which is rotatably connected to the traction frame. A traction rope is wound around the adjusting roller, and the other end of the traction rope is fixedly connected to the support arm.

[0012] Preferably, there are two sets of support arms, which are located on the front and rear sides of the hanger, respectively.

[0013] Preferably, a first pulley is rotatably connected to the traction frame, a second pulley is rotatably connected to the hanger, and a third pulley is rotatably connected to the support arm. The traction rope is wound in an M-shape around the first pulley, the second pulley, and the third pulley.

[0014] Preferably, the lifting equipment includes a winch and a wire rope, and there are two sets of both the wire rope and the sheaves. The wire rope passes around the sheaves, and the two sets of sheaves are located on the left and right sides of the lifting claw, respectively.

[0015] Preferably, a rotary table is connected to the upper end of the lifting claw, and a lifting lug is fixedly connected to the rotary table. Both sets of lifting wheels are rotatably connected to the lifting lug.

[0016] Compared with the prior art, the outstanding advantages of this utility model are: This application adds a support arm under the hanger. During the movement, the support arm is always subjected to an upward diagonal force from the traction component, so that there is always an upward support force under the hanger, which shares the concentrated load that was originally borne by the crossbeam alone. This greatly reduces the bending moment and deflection in the middle of the crossbeam, and fundamentally avoids the risk of crossbeam deformation or breakage due to excessive load.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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.

[0024] Please see the appendix Figure 1-5 This embodiment provides a support bracket for a garbage roll: it includes a crossbeam 1, a hanger 2 slidably connected to the crossbeam 1, a lifting device on the hanger 2, a wheel 4 below the lifting device, a lifting claw 5 rotatably connected to the wheel 4, traction frames 6 fixedly connected to both ends of the crossbeam 1, each of the two sets of traction frames 6 is provided with a pulling assembly, a support arm 7 fixedly connected to the pulling assembly, the support arm 7 is fixedly connected to the hanger 2, and a sliding groove 8 is provided in the support arm 7, the sliding groove 8 is slidably connected to the crossbeam 1.

[0025] The crossbeam 1 is typically mounted above the garbage pit via end beams (not shown in the figure) that are fixedly connected to both ends. A hanger 2 is slidably connected to the crossbeam 1. Specifically, the top of the hanger 2 may be equipped with wheels (not shown in the figure) that cooperate with a pre-set track on the crossbeam 1, or may be connected via other linear sliding pairs, so that the hanger 2 can reciprocate along the length of the crossbeam 1 under the drive of a drive device (such as a motor).

[0026] The lifting equipment is mounted on the lifting frame 2. In this embodiment, the lifting equipment includes a winch 301 and a wire rope 302 controlled by the winch 301. There are two sets of wire rope 302 and corresponding sheaves 4. Sheaves 4 are mounted below the lifting equipment, and are rotatably connected to grippers 5 for grabbing waste. Specifically, a rotary table 14 is connected to the upper end of the gripper 5, allowing the gripper 5 to rotate at a certain angle in the horizontal plane for precise grabbing and unloading. Lifting lugs 15 are fixedly connected to the rotary table 14, and the two sets of sheaves 4 are rotatably connected to the left and right sides of the lifting lugs 15 via bearings. The wire rope 302 passes over the corresponding sheave 4, and the opening, closing, and lifting / lowering of the gripper 5 are controlled by the winch 301.

[0027] To address the issue of weak support in the middle of the crossbeam 1, traction frames 6 are fixedly connected to both ends of the crossbeam 1. Each of the two traction frames 6 is equipped with a traction assembly; the traction assembly includes an adjusting roller 9, which is rotatably connected to the traction frame 6 via a bearing seat and can be equipped with a handwheel or motor (not shown) to drive its forward and reverse rotation. A traction rope 10 is wound around the adjusting roller 9.

[0028] The other end of the traction rope 10 is fixedly connected to a support arm 7. The support arm 7 is preferably a box girder or I-beam made of high-strength steel, which is fixedly connected to the hanger 2. More preferably, there are two sets of support arms 7, fixedly connected to the front and rear sides of the hanger 2 respectively, forming a stable two-point support to jointly bear the load from the hanger 2. A groove 8 is provided inside or on the side of the support arm 7. This groove 8 is slidably connected to the crossbeam 1. Specifically, a guide rail can be installed on the side or bottom of the crossbeam 1, and a slider (not shown in the figure) can be embedded in the groove 8, or the groove 8 itself can form a slot that directly engages with a specific flange of the crossbeam 1, thereby enabling the support arm 7 to slide longitudinally relative to the crossbeam 1.

[0029] Furthermore, to reduce wear on the traction rope 10 and ensure smooth transmission, a first pulley 11 can be rotatably connected to the traction frame 6, a second pulley 12 can be rotatably connected to the hanger 2, and a third pulley 13 can be rotatably connected to the end of the support arm 7. After the traction rope 10 is led out from the adjusting roller 9, it wraps around the first pulley 11, the second pulley 12, and the third pulley 13 in an "M" shape or similar multiple winding pattern, and is finally fixed to an appropriate position on the support arm 7 or the traction frame 6. This pulley group structure can not only change the direction of force, but also save effort or provide precise control.

[0030] The overall workflow of this application: When the hanger 2, carrying the lifting claw 5, moves on the crossbeam 1, the support arm 7, being fixedly connected to the hanger 2, moves synchronously. Simultaneously, the operator or automatic control system synchronously controls the adjusting rollers 9 at both ends to wind up and unwind the traction rope 10, ensuring that the support arm 7 always follows the hanger 2. Its sliding groove 8 moves smoothly on the crossbeam 1. Regardless of where the hanger 2 moves on the crossbeam 1, including the weakest mid-span position, the two support arms 7 provide effective vertical support on both sides of the hanger 2. This is equivalent to adding a movable "pier" below the crossbeam 1, effectively transferring the concentrated load originally borne solely by the crossbeam 1 to the traction frames 6 and end beams at both ends through the support arms 7. This structure greatly reduces the bending moment and deflection in the middle of the crossbeam 1, fundamentally avoiding the risk of deformation or breakage of the crossbeam 1 due to excessive load.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
