TECHNICAL FIELD
[0001] The utility model belongs to the technical field of spider cranes, and particularly relates to a safety early warning structure of a spider crane. BACKGROUND
[0002] A spider crane is a new type of hoisting equipment, has the shape and function of a spider, can freely move and complete various high-difficulty hoisting operations. The safety early warning structure plays a crucial role in ensuring operation safety. The spider crane can stably support the vehicle body on the ground through four extendable supporting legs, can effectively prevent the vehicle body from tilting and shaking even when hoisting heavy objects, and ensures the stability of the operation process.
[0003] Specifically, the safety early warning structure of the spider crane on the market is highly advanced, can detect obstacles near the operation environment in all directions and in real time through the integration of radar, ultrasonic and infrared sensors and other precise devices. Once the sensors detect potential obstacles, the system will immediately trigger a clear alarm signal and automatically activate the corresponding obstacle avoidance mechanism to ensure the safety of the operation process. However, it is worth noting that the safety early warning structure of most spider cranes on the current market adopts a relatively simple single bolt mounting method during assembly. Although this mounting method is convenient to operate and maintain, it also leaves multiple bolt mounting holes on the mechanical arm. The existence of these holes not only affects the appearance neatness of the mechanical arm, but also may become a stress concentration point, which may adversely affect the structural strength and durability of the mechanical arm under long-term action, thereby potentially threatening the overall performance and safety of the spider crane, and affecting the installation effect of the safety early warning structure.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] Please see Figures 1-5The present invention provides the following technical solution: a safety warning structure for a spider crane, including a monitoring top plate 1 and a monitor 2 installed on the bottom surface of the monitoring top plate 1. A distance sensor 3 is installed on the surface of the monitoring top plate 1. A wire 4 is connected to one side of the distance sensor 3 and an alarm 5 is connected to the other end of the wire 4.
[0024] A mounting plate 6 is connected to the back side of the monitoring top plate 1. Adjustment plates 7 are connected to the outer sides of both ends of the mounting plate 6. A sliding block 8 is connected to the outer wall of the mounting plate 6. A threaded rod 9 is connected to one side of the sliding block 8. A nut 10 is sleeved on the surface of the threaded rod 9.
[0025] Preferably, both the monitor 2 and the distance sensor 3 are electrically connected to the power supply cabinet, and the alarm 5 is installed on the side surface of the monitoring top plate 1. In actual use, the distance sensor 3 is used to monitor the surrounding buildings in real time. When the crane is within a dangerous distance, the distance sensor 3 will issue an alarm message, and the alarm 5 will flash to remind the operator to provide a safety warning, thereby improving the safety of the spider crane operation.
[0026] Preferably, both the mounting plate 6 and the adjusting plate 7 are made of stainless steel. The adjusting plate 7 has a sliding groove on its surface near the sliding block 8. The mounting plate 6 and the adjusting plate 7 are connected by a sliding groove on their surfaces via the sliding block 8. The surface dimension of the nut 10 is larger than the opening dimension of the adjusting plate 7, and the nut 10 is threadedly connected to the threaded rod 9. In practical use, by passing the nut 10 through the threaded rod 9, the sliding block 8 can be easily slid along the sliding groove on the surface of the adjusting plate 7, thus facilitating the adjustment of the monitor 2 to the appropriate dimensions.
[0027] Preferably, a bracket 11 is connected to the surface of the monitoring top plate 1 near the distance sensor 3. A protective plate 12, made of PVC, is connected to the inner side of the top of the bracket 11 and is positioned directly above the distance sensor 3. In practical use, the protective plate 12 facilitates the protection of the distance sensor 3.
[0028] Preferably, the protective plate 12 is connected to two ends of a rotating shaft 13, which passes through the bracket 11 and extends to the outside of the bracket 11. The other end of the rotating shaft 13 is connected to a positioning block 14. In actual use, the positioning block 14 is rotated along the inner wall of the opening of the fixing block 15, thereby facilitating the angle adjustment of the protective plate 12.
[0029] Preferably, a fixing block 15 is connected to the outer wall of the bracket 11 near the positioning block 14, and a locking spring 16 is connected to the inner wall of the fixing block 15. The other end of the locking spring 16 is connected to a locking buckle 17, and the locking buckle 17 and the opening on the surface of the positioning block 14 form a fitting structure. In actual use, by fitting the locking buckle 17 into the opening on the surface of the positioning block 14, the protective plate 12 can be easily and stably installed.
[0030] The working principle of this utility model is as follows: First, the mounting plate 6 on the back side of the monitoring top plate 1 is snapped onto the mechanical wall of the spider crane. Then, the adjusting plate 7 is slidably engaged with the mounting plate 6, causing the sliding block 8 to slide along the opening on the surface of the mounting plate 6 to adjust its position. This facilitates the assembly of the mounting plate 6 and the adjusting plate 7 on the mechanical wall. Next, the nut 10 is tightened onto the surface of the threaded rod 9, facilitating the quick assembly of the monitor 2 and avoiding drilling holes in the robotic arm, thus improving the safety of the spider crane. During the lifting process of the spider crane, the monitor 2 monitors the surrounding environment in real time, and the distance sensor 3 monitors the surrounding buildings in real time, facilitating the detection of potential hazards. When the distance is dangerously close, the distance sensor 3 issues an alarm, and the alarm 5 flashes, reminding the operator to take safety precautions and improving the safety of the spider crane operation. In addition, by rotating the protective plate 12 between the two brackets 11, the positioning block 14 at one end of the rotating shaft 13 rotates inside the fixed block 15, which in turn causes the locking buckle 17 to squeeze the locking spring 16. Then the locking buckle 17 is engaged with the opening on the surface of the positioning block 14, which facilitates the fixing of the positioning block 14 inside the fixed block 15. This ensures that the protective plate 12 is in a stable state after rotating at a suitable angle, and facilitates the use of the protective plate 12 to protect the distance sensor 3 from dust, thereby improving the service life of the distance sensor 3.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
