[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0013] Figure 1 This is a front view of a remote-controlled quay crane hoist guide plate anti-falling device provided according to an embodiment of the utility model. Figure 2 1 is a side view of a remote-controlled quay crane hoist guide plate anti-falling device according to an embodiment of the utility model. Figure 1 and Figure 2 As shown, the device is applied to a remote-controlled quay crane hoist, wherein the remote-controlled quay crane hoist includes a guide plate 1 and a guide plate motor 2, the end of the guide plate motor 2 is connected to the guide plate 1 through a Havers block 3; the Havers block 3 is fixed to the guide plate 1 through a fastening bolt 4.
[0014] Specifically, Figure 1 and Figure 2 As shown, a remote-controlled quay crane hoist guide plate anti-falling device according to an embodiment of the utility model comprises: a chain 5 and an anti-loosening bolt 6.
[0015] Specifically, one end of the chain 5 is fixed on the guide plate 1 of the remote-controlled quay crane hoist, and the other end of the chain 5 is fixed on the Harvard block 3 of the remote-controlled quay crane hoist.
[0016] Specifically, the anti-loosening bolt 6 is arranged at the side of the Harvard block 3 and is perpendicular to the setting direction of the fastening bolt 4; the tail end of the anti-loosening bolt 6 passes through the outer wall of the Harvard block 3 and is stuck in the head position of the fastening bolt 4.
[0017] Specifically, in the embodiment of the utility model, the head of the fastening bolt 4 is a circular or polygonal structure, and the tail end of the anti-loosening bolt 6 can be stuck on the edge of the head of the fastening bolt 4 to increase the friction when the fastening bolt 4 is loosened, thereby effectively preventing the fastening bolt 4 from loosening.
[0018] Preferably, the chain 5 comprises a metal chain. For example, the chain 5 comprises an iron chain.
[0019] Preferably, the number of the anti-loosening bolts 6 is two, corresponding to the two fastening bolts 4 respectively.
[0020] In the embodiment of the utility model, the loosening of the Harvard block is divided into two stages. The first stage is the initial stage. The gap of the Harvard block screw loosens and becomes larger. This stage takes about 7 to 14 days. The second stage is the final stage. Since there is already a gap between the Harvard block and the guide plate, and it is still in a high-intensity loading and unloading environment, the screw will be further worn. This will cause the screw to break or the Harvard block to fall off. Therefore, the utility model starts from the initial stage, so that the Harvard block screws are not easy to loosen in the initial stage, and ensure that the Harvard block will not easily cause a high fall after loosening.
[0021] Specifically, anti-loosening bolts are installed at the fastening bolts connecting the Harvard block and the guide plate to clamp the fastening bolts on the Harvard block, so that the fastening bolts will not loosen, thereby increasing the working period time and reducing the frequency of tightening operations. At the same time, a chain is added between the Harvard block and the guide plate to prevent the Harvard block from falling after loosening, thereby ensuring safety during the working period.
[0022] As can be seen from the above description, the embodiment of the utility model provides a remote-controlled quay crane spreader guide plate anti-falling device, which has the following advantages compared with the prior art:
[0023] (1) Reduce or even eliminate the risk of falling from a height caused by loosening of the Harvard block, making the operation safer and reducing safety hazards;
[0024] (2) This method only requires a small amount of manpower and material resources, can reduce the risk of falling objects from high altitudes, and improve safety.
[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
