[0030] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] In one specific embodiment, the bucket-holding mechanism provided by this utility model is used in a bucket tilting and lifting machine, which is a lifting machine specifically designed for confined spaces. For example... Figures 1-2 As shown, the bucket-holding mechanism includes a fixed frame 1, a guide rod 2, and a bearing seat 3; wherein, the bucket to be lifted 100 is detachably installed on the fixed frame 1, and a contact block 4 is installed on the fixed frame 1; the guide rod 2 is installed on the adapter seat 8, and a second rotating shaft 6 is slidably installed on the guide rod 2 along the axial direction, the second rotating shaft 6 is connected to the chain drive and moves with the chain in the extension direction of the guide rod; the bearing seat 3 is installed on the fixed frame 1, and a first rotating shaft 5 is fixedly installed on the bearing seat 3, the first rotating shaft 5 is connected to the chain drive and moves with the chain in the extension direction of the guide rod.

[0032] During use, the bucket to be lifted 100 is fixed on the fixed frame 1. The first rotating shaft 5 and the second rotating shaft 6 are connected to the chain drive of the bucket tilting elevator. The entire bucket-holding mechanism moves along the guide rail of the elevator under the pull of the chain. When it moves to the preset position, the contact block 4 touches the photoelectric switch at the preset position. During the movement, the guide rod 2 provides guidance, and the second rotating shaft 6 slides along the guide rod 2, realizing movement through chain drive. The first rotating shaft 5 is fixed on the bearing seat 3 and realizes synchronous movement through chain drive. In this way, the bucket-holding mechanism realizes stable bearing and lifting of the bucket, and the chain drive ensures the synchronicity of movement. The design of the guide rod 2 and the rotating shaft improves the stability and reliability of the mechanism. At the same time, when the bucket-holding mechanism rises or falls to the 90° corner, the first rotating shaft 5 and the second rotating shaft 6 rotate. Simultaneously, the second rotating shaft 6 reciprocates on the guide rod 2, thus enabling it to cooperate with the bucket tilting elevator to perform lifting and tilting actions in confined spaces.

[0033] Specifically, the fixing frame 1 includes a support part and a side plate. The bottom of the material bucket 100 to be lifted is placed on the support part, the side plate is vertically installed on the support part, and the bearing seat 3 is installed on the side plate. During use, the support part supports the bottom of the material bucket, and the side plate provides structural support and installation position, improving the structural stability of the fixing frame 1 and also providing a foundation for the installation of other components. The support part can be a plate-like structure or a frame structure, and the side plate can be a plate-like structure, a bracket, or a column, etc.

[0034] Furthermore, the fixing frame 1 also includes an adapter seat, which is installed on the side plate. The guide rod 2 is installed on the adapter seat, and the side plate and the guide rod 2 are connected by the adapter seat, providing an intermediate connection structure and reducing the installation difficulty of the guide rod 2.

[0035] The aforementioned guide rod 2 consists of two rods, which are spaced apart laterally on the adapter. The two guide rods 2 provide dual guidance, improving the smoothness of movement. It is understood that the number of guide rods 2 can be increased or decreased, adjusted according to actual needs.

[0036] Furthermore, the material bucket tilting and lifting machine also includes a connecting block, on which the two guide rods 2 are slidably mounted, and the second rotating shaft 6 is mounted on the connecting block. The connecting block connects the guide rods 2 and the second rotating shaft 6 to realize the transmission of motion, thereby improving the integration of the mechanism and the reliability of the motion.

[0037] To ensure smooth sliding connection, two guide rods are fixed on the adapter, two linear bearings are sleeved on the guide rods, and the linear bearings are fixed on the second rotating shaft; the two ends of the second rotating shaft are fixed to the chain through bearing seats and connecting plates.

[0038] Furthermore, the bucket-holding mechanism also includes a clamp 7, which is detachably mounted on the side plate, and the bucket to be lifted 100 is detachably clamped within the clamp 7. The clamp 7 clamps the bucket through its opening and closing action, achieving both fixing and releasing of the bucket, improving the reliability of the bucket's fixation and preventing loosening during lifting. The clamp 7 can be replaced by other clamping structures, such as claws or clamping plates.

[0039] In a specific application scenario, the bucket-holding mechanism includes a fixed frame 1, a bearing seat 3, a first rotating shaft 5, a second rotating shaft 6, an adjusting rod, a linear bearing, and a contact block 4. The bearing seat 3 is fixed to the fixed frame 1, the first rotating shaft 5 is fixed to the bearing seat 3, and the guide rod 2 is fixed to the fixed frame 1. The linear bearing is mounted on the second rotating shaft 6, which in turn is mounted on the guide rod 2, causing the second rotating shaft 6 to reciprocate on the guide rod 2. The contact block 4 is fixed to the fixed frame 1 and touches a limit switch on the guide rail. Both ends of the first rotating shaft 5 are connected to the chain via the bearing seat and can rotate freely relative to the chain. Both ends of the second rotating shaft 6 are also connected to the chain via the bearing seat and can rotate freely relative to the chain. When the bucket-holding mechanism rises or falls to a 90° corner, the first rotating shaft 5 and the second rotating shaft 6 rotate, and simultaneously, the second rotating shaft 6 reciprocates on the guide rod 2.

[0040] In addition to the aforementioned bucket-holding mechanism, this utility model also provides a bucket tilting and lifting machine including the bucket-holding mechanism. The bucket tilting and lifting machine further includes a frame, a guide rail, and a drive mechanism. The guide rail is mounted on the frame and sequentially includes a first vertical section, a horizontal section, and a second vertical section in its extending direction. A first inflection point is formed between the first vertical section and the horizontal section, and a second inflection point is formed between the horizontal section and the second vertical section. The drive mechanism is connected to the bucket-holding mechanism, and the bucket-holding mechanism moves along the extending direction of the guide rail under the action of the drive mechanism. When the bucket-holding mechanism reaches the first inflection point, it tilts horizontally, and when it reaches the second inflection point, it tilts vertically.

[0041] In some embodiments, the frame is further equipped with a descent deceleration photoelectric switch, a descent stop photoelectric switch, a descent safety protection photoelectric switch, an ascent deceleration photoelectric switch, an ascent stop photoelectric switch, and an ascent safety protection photoelectric switch. When the contact block 4 on the bucket-holding mechanism contacts the descent deceleration photoelectric switch, it indicates that the descent deceleration position has been reached, and the chain drives the bucket-holding mechanism to begin decelerating and descending. When the contact block 4 on the bucket-holding mechanism contacts the descent stop photoelectric switch, it indicates that the descent stop position has been reached, and the chain drives the bucket-holding mechanism to stop descending. When the contact block 4 on the bucket-holding mechanism contacts the descent safety protection photoelectric switch, it indicates that the descent stop position has been reached, and the chain drives the bucket-holding mechanism to stop descending. When the bucket clamp reaches the descent limit position, the chain will cause the bucket clamping mechanism to brake suddenly, and the alarm will sound. When contact block 4 on the bucket clamping mechanism touches the upward deceleration photoelectric switch, it indicates that the upward deceleration position has been reached, and the chain will cause the bucket clamping mechanism to begin decelerating upward. When contact block 4 on the bucket clamping mechanism touches the upward stop photoelectric switch, it indicates that the upward stop position has been reached, and the chain will cause the bucket clamping mechanism to stop upward. When contact block 4 on the bucket clamping mechanism touches the upward safety protection photoelectric switch, it indicates that the upward limit position has been reached, and the chain will cause the bucket clamping mechanism to brake suddenly, and the alarm will sound.

[0042] In general, the bucket tilting and lifting machine includes a frame, a drive sprocket assembly, multiple driven sprocket assemblies, a tension sprocket assembly, and a bucket-holding mechanism. A variable frequency geared motor (with brake) drives the drive sprocket assembly to rotate, which in turn drives the chain. The multiple driven sprocket assemblies are positioned at fixed points, causing the chain to form a circular motion. The bucket-holding mechanism reciprocates around the circular chain track. When the bucket-holding mechanism reaches a 90-degree turn, the connection point with the chain automatically rotates, and the adjusting rod in the bucket-holding mechanism automatically retracts and extends. This achieves functions such as bucket tilting and docking.

[0043] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above are only specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made on the basis of the technical solution of this utility model should be included within the scope of protection of this utility model.
