Description

Technical Field

[0001] This utility model relates to the field of stacker crane equipment technology, and in particular to a pull-out scapegoat device for stacker cranes. Background Technology

[0002] With the development of warehousing and logistics automation technology, stacker cranes have become the core equipment in modern warehousing systems, and their operational safety and reliability have attracted much attention.

[0003] To address the risk of unilateral rope overload or sinking caused by uneven weight distribution on both sides of the loading platform, a series of safety protection technologies have emerged, such as slack / broken rope protection devices and overload protection devices. These devices can trigger protection mechanisms when an anomaly is detected to prevent accidents.

[0004] In related technologies, workers enter the bottom of the loading platform to install the scapegoat into a preset fixed position in order to intervene in or protect the equipment status.

[0005] However, the installation method of the aforementioned scapegoat device requires personnel to enter the bottom of the equipment to operate, which increases the operational risk and makes it difficult to achieve a rapid response in case of emergencies, thus affecting the reliability of the protection function. Utility Model Content

[0006] In response to the shortcomings of the existing production technology, the applicant provides a pull-out scapegoat device for stacker cranes, thereby solving the safety problem of personnel when the stacker crane is being maintained on the loading platform and avoiding personnel standing under the loading platform without protection.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A pull-out scapegoat device for a stacker crane, comprising:

[0009] Scapegoat assembly, which is retractably mounted on the stacker crane column and cooperates with the loading platform;

[0010] The scapegoat assembly includes a limiting body, a cover, a base, and a handle;

[0011] The limiting body is a rod-shaped structure with a threaded hole at one end, and the handle is fixed to the threaded hole of the limiting body by a threaded connection.

[0012] The cover and the base are connected to form a receiving cavity, the limiting body is disposed in the receiving cavity, and the limiting body moves in the receiving cavity in a direction that is close to or far away from the working area of ​​the loading platform.

[0013] The stacker column is provided with a through hole, and the limiting body passes through the through hole and can be pulled and moved along the through hole;

[0014] The cover is provided with a working position and a waiting position along its length. The handle can selectively drive the limiting body to switch between the working position and the waiting position.

[0015] The number of scapegoat components is two sets, which are symmetrically installed on the stacker crane columns on both sides of the loading platform, and the two sets of scapegoat components are obliquely symmetrically distributed on the same horizontal plane.

[0016] The handles of both sets of scapegoat components are oriented on the same side of the stacker crane in the left-right direction.

[0017] As a further improvement to the above technical solution:

[0018] In one embodiment, the limiting body is made of metal steel pipe or round steel; the handle is metal round steel with threads processed at both ends, one end of which is connected to the threaded hole of the limiting body, and the other end is equipped with a flange nut.

[0019] In one embodiment, a steel plate is welded at the through hole position of the stacker crane column, and a through hole is opened in the center of the steel plate. The through hole is coaxially arranged with the through hole of the stacker crane column. A wire hole is also opened on the stacker crane column for the wire of the proximity detection switch to pass through.

[0020] In one embodiment, the housing includes a bent housing with operating paths provided on the sides and top surface of the bent housing for the movement of the handle; the base is fixed to the stacker crane column by bolts.

[0021] In one embodiment, the first detection component includes a waiting position proximity detection switch bracket and a waiting position proximity detection switch. The waiting position proximity detection switch bracket is an L-shaped bracket, with one side fixed to the base and the waiting position proximity detection switch installed on the other side, facing the waiting position. The second detection component includes a working position proximity detection switch bracket and a working position proximity detection switch. The working position proximity detection switch bracket is an L-shaped bracket, with one side fixed to the base and the working position proximity detection switch installed on the other side, facing the working position.

[0022] In one embodiment, the system further includes a first detection component and a second detection component; wherein the first detection component corresponds to a waiting position setting and is used to detect the state of the handle in the waiting position; and the second detection component corresponds to a working position setting and is used to detect the state of the handle in the working position.

[0023] In one embodiment, the scapegoat component has a surface color different from that of the stacker crane body.

[0024] In one embodiment, a pedal is also included, which is disposed on the lower crossbeam of the stacker crane to assist the operator in operating the scapegoat assembly.

[0025] In one embodiment, the scapegoat assembly is a detachable structure, the cover is connected to the base by bolts, and the handle is connected to the limiting body by threads, so that the limiting body can be replaced.

[0026] The beneficial effects of this utility model are as follows:

[0027] This utility model has a compact structure and a pull-out design. Operators can simply push the scapegoat from the waiting position to the working position by operating the handle on the left or right side of the stacker crane. This completely avoids the risk of being hit by falling objects when personnel are directly under the loading platform, thus achieving inherent safety and changing the traditional scapegoat device operation mode that requires personnel to enter the dangerous area at the bottom of the loading platform for installation.

[0028] This utility model also has the following advantages:

[0029] This utility model adopts a flange nut locking structure. When the handle drives the limit body to the designated position (working position or waiting position), the handle can be firmly connected to the surface of the cover by tightening the flange nut. This effectively suppresses the handle shaking caused by the vibration of the equipment operation, ensures the continuous stability of the proximity switch detection signal, greatly reduces the risk of false triggering or detection failure, and improves the reliability of the entire protection system.

[0030] This invention unifies the handles on both sides of the loading platform, placing them on the same side of the stacker crane. Operators no longer need to weave through narrow aisles and traverse the equipment; all operations can be completed from one side, ensuring both safety and efficiency. Furthermore, the inclusion of foot pedals accommodates operators of varying heights, making the operating posture more comfortable and effortless. These design details significantly enhance the ease of use and operational efficiency of the equipment. Attached Figure Description

[0053] like Figures 1-5 The accompanying drawing shows a schematic diagram of the structural state of a pull-out scapegoat device for a stacker crane according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0054] This utility model provides a pull-out scapegoat device for a stacker crane, which provides safe and reliable support and protection for maintenance operations of the stacker crane's loading platform 5 through a pull-out mechanical limiting structure, including a scapegoat component 1.

[0055] In some embodiments, the scapegoat assembly 1 is primarily fastened to the side of the stacker column 4 by bolts via its base 103;

[0056] Furthermore, the scapegoat assembly 1 mainly includes a limiting body 101, a cover 102, a base 103, a flange nut 104, and a handle 105; among which, the limiting body 101 is the main load-bearing component. The limiting body 101 is made of high-strength metal steel pipe or solid round steel, and its specific specifications need to be calculated and determined according to the total weight of the loading platform 5 and the impact load; at the end of the limiting body 101 away from the loading platform 5 (i.e., the non-working end), a threaded hole 106 is machined radially thereon;

[0057] The handle 105, serving as the operating component, is made of bent round steel and has threads machined at both ends. One end of the handle 105 is screwed into and secured in the threaded hole 106 of the limiting body 101, thereby achieving a rigid connection with the limiting body 101. The other end of the handle 105 mates with the flange nut 104.

[0058] The cover 102 and the base 103 are connected by bolts to form a closed or semi-closed accommodating cavity, which encloses the limiting body 101 and serves to prevent dust, protect and isolate safety.

[0059] The housing 102 specifically includes a bent housing 1021. On the side and top surfaces of the housing 1021, an operating path is reserved according to the movement trajectory of the handle 105, and two key positions are formed: the working position 1022 and the waiting position 1023.

[0060] In some embodiments, a through hole is provided on the stacker crane column 4, and the axial direction of the through hole is consistent with the horizontal running direction of the stacker crane;

[0061] To compensate for the strength reduction caused by directly drilling holes in the column profile, a steel plate 8 is welded at the through hole position of the stacker crane column 4 for local reinforcement. The steel plate 8 has a through hole in the center. The through hole and the through hole on the stacker crane column 4 must be highly concentric to ensure that the limiting body 101 can pass through smoothly.

[0062] In addition, a wire hole 8 is provided on the stacker column 4 on the side of the mounting cover 102 for the cable of the proximity detection switch to pass through, keeping the wiring neat.

[0063] In some embodiments, the limiting body 101 passes through the through hole on the stacker crane column 4 and the through hole in the reinforcing steel plate 8. The operator can move and fine-tune the limiting body 101 within the accommodating cavity by pushing, pulling, and rotating the handle 105, allowing the front end of the limiting body 101 to switch between the "waiting position" and the "working position". When locking is required, the flange nut 104 is tightened, causing its flange surface to press tightly against the outer surface of the cover 102, thereby firmly fixing the handle 105 and the limiting body 101 connected thereto in the current position, effectively preventing accidental movement caused by equipment vibration.

[0064] In some embodiments, in order to accurately detect the real-time status of the scapegoat component 1, the present invention provides a first detection component 2 and a second detection component 3;

[0065] The first detection component 2 is set to the waiting position 1023. It includes a waiting position proximity detection switch bracket 201 that is fixed to the base 103 by bolts, and a waiting position proximity detection switch 202 installed on the bracket 201.

[0066] Similarly, the second detection component 3 is set to work position 1022, and it includes a work position proximity detection switch bracket 301 that is fixed to the base 103 by bolts, and a work position proximity detection switch 302 mounted on the bracket 301.

[0067] The first detection component 2 and the second detection component 3 are used to detect whether the handle 105 has accurately reached the waiting position 1023 or the working position 1022, respectively, and transmit the detection signal to the stacker crane control system to realize the switching of the working mode.

[0068] In a preferred embodiment, there are two sets of scapegoat components 1, which are symmetrically installed on the stacker crane columns 4 on both sides of the loading platform 5, and the two sets of devices are obliquely symmetrically distributed on the same horizontal plane.

[0069] It is understandable that, such as Figure 4 As shown, the handles 105 of the two sets of scapegoat components 1 are both arranged on the same side of the stacker crane in the left-right direction. This allows operators to complete all actions from one side without having to cross narrow aisles to the other side of the equipment, greatly improving safety and convenience.

[0070] To further optimize the operating experience, a footboard 6 is installed on the lower crossbeam 7 of the stacker crane to accommodate operators of different heights.

[0071] The scapegoat component 1 is coated with a striking color that is distinctly different from the color of the stacker crane body, making it easy for operators to visually judge its position and status from a distance.

[0072] It is understood that the entire device of this utility model adopts a modular and detachable design. The cover 102 and the base 103 are connected by bolts, and the handle 105 and the limiting body 101 are connected by threads. This means that when the limiting body 101 undergoes plastic deformation due to accidental impact, a new limiting body 101 can be easily disassembled and replaced without replacing the entire column or large components, making maintenance convenient.

[0073] In practical applications, the working principle of this utility model is as follows:

[0074] When the stacker crane is operating normally, the scapegoat assembly 1 is in the "waiting position". At this time, the limit body 101 retracts, and its front end will not interfere with the normal lifting and lowering operation of the loading platform 5. The waiting position proximity detection switch 202 detects that the handle 105 is in the waiting position 1023 and sends a "safe operation" signal to the control system;

[0075] When maintenance is required on the loading platform 5, the operator stands on the footplate 6 and operates the two scapegoat components 1 sequentially from the same side of the stacker crane. Loosen the flange nut 104 and push the handle 105 from the waiting position 1023 along the pre-reserved path on the cover 102 to the working position 1022, thereby pushing the working end of the limit body 101 directly below the bottom of the loading platform 5. Then tighten the flange nut 104 to lock the position. Once the working position proximity detection switch 302 detects that the handle 105 is in position, it sends a "protection ready" signal to the control system, allowing the stacker crane to enter maintenance mode. At this time, the loading platform 5 can slowly descend until it is reliably supported by the two limit bodies 101, thus ensuring the safety of personnel below.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
