Technical Field

[0001] This utility model belongs to the field of transportation and testing technology for large marine engineering or port machinery equipment, specifically relating to a real-time stress detection system for port machinery sea tie rods. Background Technology

[0002] As port construction scales up, port equipment capacity also increases, leading to a growing demand for ultra-large lifting capacity gantry cranes, quay cranes, container cranes, and large ship unloaders. The previous methods of loading port machinery equipment into ships in loose parts and lashing large items can no longer meet current equipment transportation requirements. From domestic river ports to overseas ocean ports, choosing the safest and fastest way to transport equipment has become a crucial aspect for every port enterprise.

[0003] As large-scale port equipment, its inland waterway transportation and ocean shipping must both consider the complexity of transportation conditions and the impact of transport vessels on the equipment. Ensuring the safety and stability of the equipment during transportation requires a complete transportation lashing plan for different products, using appropriate methods to secure the equipment to the vessel to ensure smooth transport to the user's dock and rapid installation and use. Currently, there are no corresponding measures for effectively controlling transportation risks and monitoring data in real time during transportation. Summary of the Invention

[0004] To meet the intense competition in the port machinery market, effectively control transportation risks, and monitor data in real time during transportation, this utility model provides a real-time stress detection system for port machinery sea lashing rods. It monitors and collects and analyzes various port machinery shipping and river transport data to obtain the optimal structure, avoid design waste, reduce the overall weight of lashing components, and lower transportation costs.

[0005] The objective of this utility model is achieved in the following manner:

[0006] A real-time stress detection system for port machinery sea ties includes a sea tie rod body connecting the transport equipment and the ship deck. At both ends of the sea tie rod body, pin sensors are connected to the transport equipment lugs and the ship deck lugs, respectively. The pin sensors are connected to a wireless transmitter, the wireless transmitter is connected to a wireless receiver, and the wireless receiver is connected to an industrial control computer.

[0007] The aforementioned port machinery sea ties rod real-time force detection system has lugs at both ends of the sea ties rod body, with pin holes on the lugs. The pin sensor at the top passes through the lugs of the transport equipment and the pin holes on the lugs of the top of the sea ties rod body to connect the top of the sea ties rod body to the transport equipment. The pin sensor at the bottom passes through the lugs of the ship deck and the pin holes on the lugs of the bottom of the sea ties rod body to connect the bottom of the sea ties rod body to the ship deck.

[0008] In the aforementioned port machinery sea tie rod real-time force detection system, an eccentric sleeve is fitted between the end of the pin sensor and the pin hole. The eccentric sleeve and the pin hole are clearance-fitted. The eccentric sleeve is provided with a pin center hole. The end of the pin sensor is threaded into the pin center hole. The wire of the pin sensor passes through the pin center hole and is connected to the wireless transmitter. The eccentric sleeve is fixed to the ear plate by bolts.

[0009] The aforementioned real-time stress detection system for the sea tie rod of port machinery is also equipped with a shaft end baffle. Bolts pass through the shaft end baffle, eccentric sleeve and ear plate to fix the eccentric sleeve to the ear plate.

[0010] The aforementioned port machinery sea tie rod real-time stress detection system is also equipped with washers. Bolts pass through the washers, shaft end baffles, eccentric sleeves and ear plates in sequence to fix the eccentric sleeves to the ear plates.

[0011] The distance between the center of the pin center hole and the center of the eccentric sleeve in the aforementioned port machinery sea tie rod real-time force detection system is 15mm.

[0012] Compared with the prior art, the present invention has the following technical effects:

[0013] This invention uses a pin-shaft sensor to collect and transmit force data at both ends of the tie rod via a wireless transmitter. A wireless receiver then transmits the data to an industrial control computer in the ship's office. The industrial control computer connects to peripheral devices such as printers and monitors.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between 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.

[0022] The following is combined Figure 1-4 The specific implementation method of this utility model is described in detail.

[0023] Since the 1990s, the overall design of some electronic weighing instruments has begun to move away from the traditional component assembly structure, developing towards diversification and personalization. One major development trend is the integrated structure that combines the load-bearing device and the load cell into one unit. In this case, the load-bearing device is a dedicated load cell that fully meets the technical requirements, or the load cell itself is an integral load-bearing device. The pin-type sensors used in electronic crane scales and overhead crane scales are typical examples of this structure. This invention uses pin-type sensors at both ends of the sea tie rod to collect the force at both ends of the sea tie rod in real time. The specific structure of this invention is as follows:

[0024] like Figure 1As shown, a real-time force detection system for port machinery sea lashing rods includes a sea lashing rod body 3 connecting the transport equipment to the ship's deck. Pin-shaft sensors 13 are connected to the transport equipment's lug 2 and the ship's deck's lug 4 at both ends of the sea lashing rod body, respectively. The pin-shaft sensors are connected to a wireless transmitter, which in turn communicates with a wireless receiver. The wireless receiver is connected to an industrial control computer. The wireless transmitter is installed near the sea lashing rod, while the wireless receiver and industrial control computer are installed in the ship's cabin office.

[0025] like Figure 2 and Figure 3 As shown, the port machinery sea ties rod real-time force detection system of this utility model has ear seats 14 at both ends of the sea ties rod body. The ear seats are provided with pin holes 12. The pin sensor at the top passes through the transport equipment pull ear 2 and the pin hole 16 on the top ear seat of the sea ties rod body to connect the top of the sea ties rod body to the transport equipment. The pin sensor at the bottom passes through the ship deck pull ear 4 and the pin hole on the bottom ear seat of the sea ties rod body to connect the bottom of the sea ties rod body to the ship deck.

[0026] The port machinery sea tie rod real-time force detection system of this utility model has an eccentric sleeve 15 sleeved between the end of the pin sensor and the pin hole. The eccentric sleeve and the pin hole are clearance-fitted. The eccentric sleeve has a pin center hole. The end of the pin sensor is threaded into the pin center hole. The pin center hole is a wire outlet hole. The wire 7 of the pin sensor passes through the wire outlet hole and is connected to the wireless transmitter. The eccentric sleeve is fixed to the ear plate by bolts 8.

[0027] The port machinery sea tie rod real-time force detection system of this utility model is also provided with a shaft end baffle 10. Bolts pass through the shaft end baffle 10, the eccentric sleeve 15 and the ear plate 14 to fix the eccentric sleeve on the ear plate.

[0028] The port machinery sea tie rod real-time force detection system of this utility model is also provided with a washer 9. The bolt passes through the washer 9, the shaft end baffle 10, the eccentric sleeve 15 and the ear plate 14 in sequence to fix the eccentric sleeve to the ear plate.

[0029] This invention effectively controls transportation risks and monitors data in real time during transportation, including real-time detection of the stress on the sea lashing rods of port machinery. It monitors and collects receipts for various types of port machinery transported by sea and river, analyzing them to obtain an optimized structure, avoiding design waste, reducing the overall weight of the lashing components, and lowering transportation costs. Furthermore, the pin-shaft sensor structure and eccentric sleeve structure at both ends of the sea lashing rod significantly improve the efficiency of loading and unloading the equipment quickly. The sea lashing rod is also easy to load and unload, reusable, has a short delivery time, and low cost, making it innovative, practical, and worthy of widespread application.

[0030] The eccentricity of the eccentric sleeve of the sea tying rod described in this utility model is 15mm, that is, the distance between the center of the center hole of the mounting pin of the eccentric sleeve and the center of the eccentric sleeve is 15mm. The maximum eccentricity of the top and bottom ends of the sea tying rod of this utility model is 15mm, and the total eccentricity at both ends is 30mm.

[0031] The adjustment method for the adjustable sea ties tie rod of this utility model is as follows: Insert the closest end of the eccentric sleeve 12 into the tie rod hole, and use an internal thread socket wrench suitable for the eccentric sleeve to clamp the external thread of the eccentric sleeve on both sides. Rotate at a certain angle to subject the sea ties tie rod to a certain preload. When the force is large, a hand chain hoist or crane can be used for adjustment. After adjustment, install the shaft end baffle and tighten the bolts; the user should follow the reverse steps when unloading on site. During sea or river transport, the eccentric sleeve and pin sensor must always be under stress for safety and reliability.

[0032] like Figure 1 As shown, the pin sensor and wireless transmitter of this utility model constitute the acoustic data acquisition system for the sea tie rod, and the wireless receiver and industrial control mechanism constitute the weighing management system of this utility model.

[0033] The following description uses a ship unloader as an example to illustrate the usage of this utility model. The entire weight of the ship unloader rests on the lower crossbeam of the gantry. The lower crossbeam consists of multiple sets of balance beams, trolleys, and wheel sets. Because the wheel sets roll, and they need to be rolled onto the ship during loading and unloading, they cannot be removed. Therefore, the degree of freedom of the lower crossbeam must be controlled to ensure that the entire equipment is integrated with the ship's structure to resist the impact of wind and waves during transportation.

[0034] 1. Lower crossbeam 2. Lower crossbeam lug 3. Adjustable sea lashing rod 4. Deck lug 5. Transport ship 6. Operating mechanism

[0035] like Figure 4 As shown, several sea ties 2 are pre-designed and installed on the side web or bottom plate of the lower crossbeam 1. These sea ties, together with the adjustable sea tie rods 3 and the deck lugs 4 of this utility model, form a sea tie rod assembly. Each sea tie rod assembly controls the operating mechanism 6 placed on the hull 5, preventing the operating mechanism from moving during sea (river) transport, thereby controlling the degree of freedom of the lower operating mechanism of the whole machine. The force on the sea tie rod is transmitted to the wireless transmitter in real time through the pin sensor. The wireless transmitter receives the force signal and then transmits it to the industrial control computer, which displays or prints it for real-time monitoring, ensuring safe arrival at the designated port.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
