Description

Technical Field

[0001] This utility model relates to a novel proximity switch detection mechanism for the telescopic beam of a stacker spreader, belonging to the field of port container technology. Background Technology

[0002] With the rapid development of globalization, the throughput of port containers is increasing day by day, and port logistics transportation has become the mainstream mode of transportation. Against this backdrop, continuously optimizing port container stacker products can create a strong competitive advantage for the company.

[0003] Currently, the telescopic beam of the spreading equipment is typically adjusted by the operator visually estimating the distance. Existing testing mechanisms are mostly split structures, with the detection switch and detection plate installed separately on the main beam and telescopic beam. This type of split testing mechanism, because the detection parameters of the detection switch are at the millimeter level, places high demands on the actual manufacturing process, resulting in high manufacturing costs. Especially on structures with large telescopic distances, the accuracy requirements are difficult to control, requiring a significant amount of time for adjustment during actual assembly and debugging. Furthermore, as the equipment is used for a longer period, the decreasing accuracy can lead to an increased failure rate of the detection switch, resulting in frequent maintenance and affecting the equipment's lifespan and product competitiveness. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a novel proximity switch detection mechanism for the telescopic beam of a forklift spreader, which reduces processing accuracy requirements, shortens assembly and debugging time, reduces failure rate, lowers cost, and improves product competitiveness.

[0005] This utility model is achieved through the following technical solution: a novel proximity switch detection mechanism for the telescopic beam of a forklift spreader, characterized in that it includes a fixed bracket assembly, a proximity switch electrical appliance, a detection slide plate structure, and a baffle limiting structure; the proximity switch electrical appliance is fixed on the fixed bracket assembly, the fixed bracket assembly is fixed to the main beam of the spreader, the detection slide plate structure and the limiting bolt assembly are combined and installed on the fixed bracket assembly, and the baffle limiting structure is installed on the telescopic beam of the spreader.

[0006] The fixed bracket assembly is provided with machined holes for controlling the lateral movement of the detection slide structure, and the limit bolt assembly is used to partially constrain the longitudinal direction of the detection slide structure.

[0007] The detection slide plate structure is provided with an opening and a limiting elongated hole. The proximity switch is located at the opening, and the limiting elongated hole is connected to the limiting bolt assembly. When the detection slide plate structure hangs down naturally, the proximity switch cannot detect the detection slide plate structure.

[0008] The fixed bracket assembly is provided with a lug plate that is connected to the limit bolt assembly. The limit bolt assembly movably connects the detection slide plate structure to the fixed bracket assembly through the lug plate.

[0009] The fixed bracket assembly is provided with bolt holes for connection with the proximity switch, and the proximity switch is fixed to the fixed bracket assembly by bolts.

[0010] The mechanism operates as follows: when the spreader telescopic beam is in its normal extended state, the detection slide structure hangs down naturally under gravity, and the proximity switch is not activated at this time; when the spreader telescopic beam retracts to a certain extent, the detection slide structure contacts the baffle limit structure and slides according to the design dimensions; when it slides to the set value, the proximity switch senses the detection slide structure and outputs a signal to decelerate and stop the telescopic beam.

[0011] The beneficial effects of this utility model are: it eliminates the original scheme of separately arranging the detection slide and the detection switch, resulting in a more compact structure, reduced precision requirements for production and debugging, and lower equipment production costs. Through integrated assembly, it better meets the detection accuracy requirements of proximity switches, improves equipment stability, and reduces subsequent maintenance costs. It reduces the failure rate of detection switches caused by decreased precision due to increased equipment usage time, extending the equipment's lifespan. It reduces the frequency of subsequent maintenance, lowers product manufacturing costs, and enhances product competitiveness. Attached Figure Description

In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0016] like Figures 1 to 5 The diagram illustrates a novel proximity switch detection mechanism for the telescopic beam of a forklift spreader, comprising a fixed support assembly 1, a proximity switch 2, a detection slide plate structure 3, and a baffle limiting structure 4. The proximity switch 2 is fixed to the fixed support assembly 1, which is also fixed to the main beam 6 of the spreader. The detection slide plate structure 3 and a limiting bolt assembly 5 are assembled and installed on the fixed support assembly 1, and the baffle limiting structure 4 is installed on the telescopic beam 7. The fixed support assembly 1 has a machined hole 11 for controlling the lateral movement of the detection slide plate structure 3, and the limiting bolt assembly 5 for partially constraining the longitudinal direction of the detection slide plate structure 3. The detection slide plate structure 3 has an opening 31 and a limiting elongated hole 32. The proximity switch 2 is positioned at the opening 31, and the limiting elongated hole 32 is connected to the limiting bolt assembly 5. When the detection slide plate structure 3 hangs naturally, the proximity switch 2 cannot detect it.

[0017] During assembly, first fix the proximity switch 2 to the fixed bracket assembly 1 with bolts, then fix the fixed bracket assembly 1 to the main beam 6 of the lifting device with bolts. Next, assemble and install the detection slide structure 3 and the limit bolt assembly 5 on the fixed bracket assembly 1. Use the machined holes on the fixed bracket assembly 1 to control the lateral movement of the detection slide structure 3. Use the limit bolt assembly 5 to partially constrain the longitudinal movement of the detection slide structure 3. Finally, install the baffle limit structure 4 on the telescopic beam 7 of the lifting device with bolts.

[0018] During operation, the telescopic beam extends normally, and the detection slide structure 3 hangs down naturally under gravity, while the proximity switch 2 is in an off state. When the telescopic beam retracts to a certain extent, the detection slide structure 3 contacts the baffle limit structure 4 and slides according to the design dimensions. When it slides to the set value, the proximity switch 2 senses the detection slide structure 3 and outputs a signal to slow down and stop the telescopic beam. 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.
