Description

Technical Field

[0001] This utility model relates to the field of automated conveying equipment for logistics, and in particular to a locking mechanism for a lift in an accumulation chain conveying system. Background Technology

[0002] In a chain conveyor system, the elevator, as the core equipment connecting conveyor lines at different heights and realizing the lifting and transfer of goods, directly determines the continuous operating efficiency and operational safety of the entire conveyor system through its operational stability and position locking accuracy. Currently, the industry mostly uses tongue-type locking devices for locking elevators, specifically mechanical pins or spring-loaded tongue structures: when the elevator is raised to the target position, the drive mechanism drives the tongue to extend and insert it into the pre-set groove of the corresponding track, thereby achieving mechanical fixation of the elevator.

[0003] The aforementioned device has the following drawbacks: due to fluctuations in the weight of the conveyed workpiece, track installation errors, and structural deformation after long-term operation, misalignment between the elevator track and the fixed track is prone to occur, leading to a decrease in the fitting accuracy of the tongue and groove. Frequent scraping occurs during insertion. The impact force during workpiece transfer and the elevator's own weight are all applied to the contact area between the tongue and groove, causing the tongue to be subjected to periodic impact loads for a long time, making it prone to bending deformation or even breakage, which in turn leads to locking failure. More seriously, with repeated wear between the tongue and the track, the track groove will gradually expand, further aggravating the misalignment problem and forming a vicious cycle of wear, misalignment, and severe wear. Ultimately, it is necessary to stop the machine to replace the tongue or repair the track, which not only increases equipment maintenance costs but also seriously affects the continuous operating efficiency of the accumulation chain conveyor system. Therefore, a locking mechanism for the elevator in the accumulation chain conveyor system is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a locking mechanism for a hoist in an accumulation chain conveyor system, which aims to improve the problems of existing tongue-type locking devices being susceptible to deformation and breakage due to impact loads, having poor adaptability to rail deviations, and being prone to locking failure after long-term use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a locking mechanism for a hoist in an accumulation chain conveyor system, comprising a crane column auxiliary beam, a lifting rail connecting frame, a cylinder, a locking roller assembly, and a locking hook assembly. The locking roller assembly is mounted on the lifting rail connecting frame and is used to lock the hoist. The locking hook assembly is mounted on the crane column auxiliary beam and is used to drive and control the locking roller assembly. The locking hook assembly includes a mounting base, a secondary rod, a main rod, and a locking hook component. The mounting base is fixedly mounted on the crane column auxiliary beam. The cylinder is hinged to the mounting base. The secondary rod is hinged to the left end of the main rod. An auxiliary groove is provided on the outer side of the locking hook component. The right end of the main rod is hinged to the locking hook component through the auxiliary groove.

[0006] As a further description of the above technical solution: the locking hook assembly also includes an output rod, a fixed sleeve, a fixed plate, and a rotating seat. The output rod is fixedly installed at the output end of the cylinder, the fixed sleeve is detachably connected to the bottom end of the output rod, the fixed plate is fixedly installed on the auxiliary beam of the crane column, and the rotating seat is fixedly installed on the fixed plate.

[0007] As a further description of the above technical solution: the bottom end of the fixing sleeve is fixedly installed on the main rod.

[0008] As a further description of the above technical solution: the left end of the auxiliary rod is rotatably connected to the rotating seat.

[0011] As a further description of the above technical solution: the outer surface of the locking hook is set in an L-shape, and the top end of the locking hook is rotatably connected to the auxiliary beam of the crane column.

[0012] As a further description of the above technical solution: the outer wall of the locking hook is in contact with the locking roller.

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.

[0018] Reference Figure 1 - Figure 3This utility model provides an embodiment of a locking mechanism for a lifting platform in an accumulation chain conveyor system, comprising a crane column auxiliary beam 10, a lifting rail connecting frame 12, and a cylinder 11. The crane column auxiliary beam 10 serves as the mounting base for components such as the locking hook assembly 1, connecting plate 11, and fixing plate 108, providing support for the entire locking mechanism and ensuring its structural strength and positional stability. The lifting rail connecting frame 12 serves as the mounting base for components such as the locking roller assembly 8, the auxiliary screw 7, and connecting plate 11, and cooperates with the crane column auxiliary beam 10 to form the mounting frame of the locking mechanism. The frame ensures the connection and coordinated operation of the locking mechanism with the lifting rail of the elevator. The locking roller assembly 8 and the locking hook assembly 1 are mounted on the lifting rail connecting frame 12 and are used to lock the elevator. The locking roller assembly 8 contains a locking roller 9. The locking hook assembly 1 is mounted on the auxiliary beam 10 of the crane column and is used to drive and control the locking roller assembly 8. A main screw 2 is fixedly mounted on the upper surface of the auxiliary beam 10 of the crane column. The main screw 2 cooperates with the washer 3, nut 4, and connecting plate 5 to realize the locking hook assembly 1's connection with the auxiliary beam 10 of the crane column. The detachable connection and position adjustment on the 0-axis are achieved by detachably connecting the main screw 2 to the connecting plate 5 via washers 3. Connecting plate 5 serves to assist in fixing the connection between the locking hook assembly 1 and the auxiliary beam 10 of the crane column, enhancing structural stability. Washers 3 are respectively fitted onto the main screw 2 and the auxiliary screw 7 to increase the contact area between the screw and the connecting plate, distribute pressure, prevent damage to the connecting plate and screw due to the pressure during tightening of the nut 4, and enhance connection stability. The auxiliary screw 7 is fixedly installed on the outer side of the lifting rail connecting frame 12, and the auxiliary screw 7 is used to cooperate with washers 3. Nut 4 and connecting plate 2 6 enable detachable connection and position adjustment between the structure containing the locking roller assembly 8 and the lifting rail connecting frame 12. The auxiliary screw 7 is detachably connected to the connecting plate 2 6 via washer 3. The connecting plate 2 6 serves to assist in fixing the connection between the lifting rail connecting frame 12 and the auxiliary screw 7, enhancing structural stability. The main screw 2, auxiliary screw 7, and nut 4 correspond to each other. Nut 4 cooperates with the main screw 2 and auxiliary screw 7 to fasten the connecting plate 1 5 and connecting plate 2 6 onto the main screw 2 and auxiliary screw 7 respectively, achieving detachable connection and fixation of components.

[0019] Reference Figure 1 - Figure 3The locking hook assembly 1 includes a mounting base 101, a secondary rod 104, a main rod 105, and a locking hook component 106. The mounting base 101 is fixedly mounted on the auxiliary beam 10 of the crane column. The mounting base 101 is used to hinge the cylinder 11, providing a fulcrum for mounting and hinge, ensuring the positional stability of the cylinder 11 during operation. The cylinder 11 is hinged to the mounting base 101. The cylinder 11 provides power through the output rod 102 at its output end, driving the main rod 105, secondary rod 104, and other components of the locking hook assembly 1 to move. It is the power source of the locking hook assembly 1. The secondary rod 104 is hinged to the left end of the main rod 105. The left end of the secondary rod 104 is rotatably connected to a rotating seat 109. The secondary rod 104, together with the main rod 105 and the rotating seat 109, forms a linkage structure, assisting the main rod 105 in its movement and ensuring the stability of the locking hook assembly 1's operation. For accuracy, the outer side of the locking hook 106 is provided with an auxiliary groove 107. The auxiliary groove 107 provides space for the hinge between the main rod 105 and the locking hook 106, and at the same time adapts to the movement trajectory of the main rod 105 when the locking hook 106 rotates, ensuring the smoothness of the linkage action. The outer surface of the locking hook 106 is set as L-shaped. The top of the locking hook 106 is rotatably connected to the auxiliary beam 10 of the crane column. The outer wall of the locking hook 106 is in contact with the locking roller 9. The right end of the main rod 105 is hinged to the locking hook 106 through the auxiliary groove 107. The main rod 105 is the core linkage component for power transmission and action linkage in the locking hook assembly 1. It transmits the power of the cylinder 11 to the locking hook 106. The locking hook 106 is the direct execution component for locking and unlocking the elevator. It achieves cooperation with the locking roller 9 through its own rotation.

[0020] Reference Figure 1 - Figure 3 The locking hook assembly 1 also includes an output rod 102, a fixing sleeve 103, a fixing plate 108, and a rotating seat 109. The output rod 102 is fixedly installed at the output end of the cylinder 11. The fixing sleeve 103 is detachably connected to the bottom end of the output rod 102. The bottom end of the fixing sleeve 103 is fixedly installed on the main rod 105. The fixing plate 108 is fixedly installed on the auxiliary beam 10 of the crane column. The fixing plate 108 is used to fix the rotating seat 109, providing a stable installation base for the rotation of the auxiliary rod 104. The setting of the fixing plate 108 limits the rotation range of the auxiliary rod 104, ensuring the movement trajectory of the main rod 105, so that the locking hook 106 is always in contact with the locking roller 9. The rotating seat 109 is fixedly installed on the fixing plate 108. The rotating seat 109 provides a rotation fulcrum for the auxiliary rod 104, ensuring the stability of the action of the auxiliary rod 104.

[0021] Working principle: The auxiliary beam 10 of the crane column serves as the installation base for components such as the locking hook assembly 1, connecting plate 1 5, and fixing plate 108, providing support for the entire mechanism and ensuring structural strength and positional stability. The lifting rail connecting frame 12 serves as the installation base for components such as the locking roller assembly 8, auxiliary screw 7, and connecting plate 2 6, and together with the auxiliary beam 10 of the crane column, forms an installation frame to ensure the connection and coordinated operation of the locking mechanism and the lifting rail of the elevator.

[0022] When the elevator needs to be locked, cylinder 11, acting as a power source, begins to operate. Its output rod 102 pushes the fixed sleeve 103, thereby driving the main rod 105 to move. The auxiliary rod 104, hinged to the left end of the main rod 105, uses a rotating seat 109 as a fulcrum. The rotating seat 109 is fixed to a fixed plate 108, which is mounted on the auxiliary beam 10 of the crane column, providing a stable base for the auxiliary rod 104's rotation. The auxiliary rod 104 moves with the main rod 105, and this linkage structure ensures the stability and accuracy of the movement. The right end of the main rod 105 drives the locking hook 106 to rotate around its hinge point with the auxiliary beam 100 of the crane column via an auxiliary groove 107 on its outer side. The outer surface of the locking hook 106 is L-shaped, and its outer wall contacts the locking roller 9 installed inside the locking roller assembly 8. As the locking hook 106 rotates, it locks the locking roller 9, thus locking the elevator. During this process, the main screw 2, washer 3, nut 4, and connecting plate 5 cooperate to achieve the detachable connection and position adjustment of the locking hook assembly 1 on the auxiliary beam 10 of the crane column, enhancing the stability of the locking hook assembly 1 connection. The auxiliary screw 7, washer 3, nut 4, and connecting plate 6 cooperate to achieve the detachable connection and position adjustment of the structure where the locking roller assembly 8 is located and the lifting rail connecting frame 12, enhancing the stability of the locking roller assembly 8 connection. Among them, washer 3 increases the contact area between the screw and the connecting plate, disperses pressure, and prevents damage to components. The mounting base 101 is fixed on the auxiliary beam 10 of the crane column, providing a hinge fulcrum for the cylinder 11, ensuring the positional stability of the cylinder 11 when it operates. The fixing sleeve 103 connects the output rod 102 and the main rod 105, facilitating power transmission and component disassembly and maintenance.

[0023] When unlocking is required, cylinder 11 reverses its action, and output rod 102 pulls fixed sleeve 103 and main rod 105. Through the cooperation of auxiliary rod 104, main rod 105 and auxiliary groove 107, locking hook 106 rotates in the opposite direction, causing it to separate from locking roller 9 and release the locking of the elevator.

[0024] The locking mechanism is powered by the cylinder 11 and driven by a linkage structure consisting of the output rod 102, the fixed sleeve 103, the main rod 105, and the auxiliary rod 104. This drives the locking hook 106 to engage or disengage with the locking roller 9, thereby locking and unlocking the elevator. At the same time, the stability and adjustability of the connections between the various structures are ensured by components such as the main screw 2, the auxiliary screw 7, the washer 3, the nut 4, the connecting plate 1 5, and the connecting plate 2 6. The gantry column auxiliary beam 10 and the lifting rail connecting frame 12 provide overall installation support, thus completing the locking control function of the elevator in the accumulation chain conveyor system.

[0025] 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.
