Description
Technical Field
[0001] The utility model relates to the field of port loading and unloading equipment, in particular to an emergency pushing device for a quay crane vehicle. Background Art
[0002] In port loading and unloading operations, quay cranes are important operating equipment. However, quay cranes are large-scale lifting equipment on the shore. Once the equipment loses power, it will have a huge impact on the departure of large ships, which will have a negative impact on the company's production and reputation. Therefore, when the quay crane fails, it needs to be opened quickly to avoid the expansion of the impact range, but the existing propulsion or traction equipment may not meet the needs. Therefore, an emergency pushing device with simple structure, easy operation, safety and reliability is needed. Utility Model Content

[0026] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the utility model, and 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 making creative work are within the scope of protection of the utility model.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0028] This embodiment discloses an emergency pushing device for a quay crane trolley, which is mainly used in ports and other places. When a quay crane trolley fails or loses power, one of the quay crane trolleys can be pushed manually or by other power sources, thereby driving the other quay crane trolley to move synchronously, ensuring that the loading and unloading operation can continue. Figure 1-Figure 2 As shown, it includes a first push block 1, a second push block 2, a first push rod 3, a second push rod 4 and a guide block 5. The first push block 1 is used to connect with the first quay bridge trolley to transmit the thrust to the first quay bridge trolley; the second push block 2 is connected with the second quay bridge trolley to transmit the thrust to the second quay bridge trolley; the adjustment end b of the first push rod 3 is connected with the first push block 1, and the pressing end a of the first push rod 3 is pressed against the second push rod 4; the adjustment end b of the second push rod 4 is connected with the second push block 2, and the pressing end a of the second push rod 4 is pressed against the first push rod 3; the guide block 5 is sleeved on the periphery of the mutually pressing part of the first push rod 3 and the second push rod 4, is fixedly connected with the first push rod 3, and is connected with the rotating shaft of the second push rod 4, allowing the second push rod 4 to rotate a certain angle in the guide block 5.
[0029] Specifically, one side of the first push block 1 is fixedly connected to the first quay crane trolley by bolts or other fixings, and the other side is provided with a threaded hole, which is threadedly connected to the first push rod 3; the second push block 2 is similar to the first push block 1, one side of the second push block 2 is fixedly connected to the second quay crane trolley, and the other side is provided with a threaded hole, which is threadedly connected to the second push rod 4. This connection method allows the first push block 1 to adjust its position on the first push rod 3 and the second push block 2 to adjust its position on the second push rod 4 to adapt to the spacing between different quay crane trolleys.
[0030] A cavity 50 is provided inside the guide block 5, and a rotating hole 51 is provided at the bottom of the cavity 50, and the rotating hole 51 extends to the other side of the guide block 5. The first push rod 3 enters the cavity 50 through the opening of the cavity 50, and the second push rod 4 enters the cavity 50 through the rotating hole 51. In the cavity 50, the first push rod 3 and the second push rod 4 are pressed against each other. Thus, the guiding and fixing of the pressing end a of the first push rod 3 and the pressing end a of the second push rod 4 are achieved.
[0031] When it is necessary to push or tow the quay crane trolley, the operator can apply force to the first push rod 3 and the second push rod 4. At the same time, the first push rod 3 and the second push rod 4 are threadedly connected to the first push block 1 and the second push block 2, and the thrust transmitted will directly act on the first quay crane trolley and the second quay crane trolley. The first push rod 3 is fixedly connected to the guide block 5, so in the process of rotating the first push rod 3, the first push rod 3 is directly driven to push or tow the first quay crane trolley. The second push rod 4 is connected to the guide block 5 by a rotating shaft, allowing it to rotate relative to the guide block 5 under the action of the thrust. When the second push rod 4 is subjected to thrust, it will use the rotating shaft as a fulcrum to transmit the thrust to the second push block 2, thereby pushing or towing the second quay crane trolley. Through the above working principle, the emergency pushing device for the quay crane trolley can effectively push or tow the quay crane trolley in an emergency situation, ensuring the safety and smooth progress of port loading and unloading operations.
[0032] In some optional embodiments, the first push rod 3 has a first protrusion 30 at the top end a, and a plug hole 31 is provided on the side wall of the protrusion. A through hole 52 is provided on the side wall of the guide block 5, and the plug hole 31 and the through hole 52 are fixedly connected by a latch 53 to ensure that the relative position between the first push rod 3 and the guide block 5 is stable.
[0033] In some optional embodiments, a second protrusion 40 is provided at the tightening end a of the second push rod 4, and the diameter of the protrusion is larger than the diameter of the rotating hole 51, so that the second protrusion 40 and the bottom of the cavity 50 are pressed against each other, thereby preventing the second push rod 4 from falling off from the guide block 5 during rotation.
[0034] In some optional implementations, a buffer pad 41 is provided between the second protrusion 40 and the bottom of the cavity 50 to reduce the impact and wear on the second push rod 4 and the guide block 5 caused by the pressing.
[0035] In some optional implementations, a thrust detection sensor 6 is provided between the first push rod 3 and the second push rod 4 for real-time monitoring of the magnitude and direction of the thrust and transmitting the data to the control system or the operator so as to timely adjust the thrust force and direction.
[0036] In some optional implementations, the side walls of the first push rod 3 and the second push rod 4 are radially provided with a rotating rod 7, so that the operator can use a tool to rotate the push rod, thereby increasing the flexibility and convenience of the operation. In addition, if the operator cannot rotate the rotating rod 7 directly due to insufficient strength, a group of force rods can be arranged outside the rotating rod 7, so that the operator can smoothly rotate the rotating rod 7.
[0037] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
