Description

Technical Field

[0001] This utility model relates to the field of stop components for port containers, specifically to a container stop mechanism for a port container intelligent guide vehicle. Background Technology

[0002] With the rapid development of intelligent driving and new energy technologies, intelligent driving and pure electric technologies are being increasingly widely applied in various industries. Currently, container shipping is ubiquitous globally, and some port container logistics terminals utilize fully electric unmanned flatbed trucks such as IGVs (Intelligent Guided Vehicles) as cargo transport vehicles. When using IGVs to transport containers, logistics terminals need to prevent containers from shifting and causing hazards.

[0003] To address this, existing IGVs typically have a container stop mechanism installed on the chassis. This effectively prevents containers from shifting forward or backward during short-distance transport in ports, locks the container's position, facilitates quay cranes and rail-mounted gantry cranes in grabbing the container, and greatly improves the container's operational efficiency.

[0004] Chinese patent document (CN214934127U) discloses a box-type stopping mechanism for an intelligent guided vehicle used in horizontal transportation at an automated terminal, and the intelligent guided vehicle itself. The box-type stopping mechanism includes a bracket, a stop pin, a pad, a base plate, and a compression rebound component. The bracket has openings at its top and bottom. The stop pin passes through these openings, partially inside the bracket and partially extending outside. The pad is located below the top opening of the bracket and is fixedly fitted to the stop pin. The compression rebound component is located inside the bracket, with its top abutting against the pad and its bottom abutting against the bottom surface of the bracket. The base plate is located below the bottom opening of the bracket and is fixedly connected to the bottom of the stop pin. However, this box-type stopping mechanism still has certain drawbacks. Because all components are in direct contact, when the compressed helical spring rebounds, the components directly and rigidly collide, producing a metal-on-metal noise, and the paint is quickly worn away. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a container stop mechanism for intelligent guided vehicles for ports, which solves the problem of direct hard contact between the components of such container stop mechanisms, avoids metal-on-metal noise, and prevents premature wear of the paint on the components.

[0006] The objective of this utility model is achieved through the following technical solution: This container stop mechanism for a port container intelligent guided vehicle includes:

[0007] The bracket has a top plate at the top and a bottom plate at the bottom, with an upper opening on the top plate and a lower opening on the bottom plate;

[0008] The stop pin slides up and down through the bracket, with the upper end of the stop pin protruding upward from the top opening and the lower end of the stop pin protruding downward from the bottom opening.

[0009] A pad is set below the upper opening and fixedly sleeved on the outer periphery of the stop pin. The pad cooperates with the upper opening to achieve the limit, and a noise-absorbing and friction-reducing pad B is set on the upper surface of the pad.

[0010] A limiting plate is located below the lower opening and fixed to the bottom of the stop pin. The limiting plate cooperates with the lower opening to achieve limiting, and a noise-absorbing and wear-reducing pad A is provided on the upper surface of the limiting plate; and

[0011] A compression elastic element is formed, with one end resting against a pad and the other end resting against a base plate.

[0012] As a further technical solution, the outer diameter of the pad and the noise-reducing and friction-reducing pad B is larger than the inner diameter of the upper opening.

[0013] As a further technical solution, the outer diameter of the limiting plate and the noise-reducing and friction-reducing pad A is larger than the inner diameter of the lower opening.

[0014] As a further technical solution, bolts are also included, which pass through the limiting plate and the noise-reducing and wear-reducing pad A in sequence and are then connected and fixed to the bottom of the stop pin.

[0015] As a further technical solution, the length of the stop pin extending out of the upper opening is less than or equal to the compression stroke of the compression elastic element.

[0016] As a further technical solution, the compression elastic element is a compression helical spring.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. Noise-absorbing and wear-reducing pads are installed on the pads and limit plates of the stopping mechanism. When the stopping pin moves upward, it contacts the top plate and bottom plate through the noise-absorbing and wear-reducing pads, which plays a buffering role, avoiding the noise of iron hitting iron and the premature wear of paint, and extending the service life of the stopping mechanism.

[0019] 2. Noise-absorbing and wear-reducing pads can be directly installed on the original housing stop mechanism. The noise-absorbing and wear-reducing pads used are made of materials with properties such as wear resistance, impact resistance, corrosion resistance, low temperature resistance, self-lubrication, and noise reduction, and have excellent buffering and vibration reduction performance.

[0023] The present invention will now be described in detail with reference to the accompanying drawings:

[0024] Example: As attached Figure 1 , 2 As shown, this container stop mechanism for a port container intelligent guide vehicle includes a bracket 1, a stop pin 2, a compression elastic element (compression coil spring 3), a pad 4, a limit plate 5, a bolt 6, a noise reduction and friction reduction pad A7, a noise reduction and friction reduction pad B8, a top plate 9, a bottom plate 10, an upper opening 11, and a lower opening 12.

[0025] Reference Appendix Figure 1 A top plate 9 is provided at the top of the bracket 1, and a bottom plate 10 is provided at the bottom of the bracket 1. The top plate 9 has an upper opening 11, and the bottom plate 10 has a lower opening 12.

[0026] Furthermore, the stop pin 2 is slidably inserted into the bracket 1 (between the upper opening 11 and the lower opening 12), with the upper end of the stop pin 2 protruding upwards from the upper opening 11 and the lower end protruding downwards from the lower opening 12. Additionally, a pad 4 is placed below the upper opening 11, and the pad 4 is fixedly fitted around the outer periphery of the stop pin 2. A sound-absorbing and friction-reducing pad B8 is provided on the upper surface of the pad 4. Preferably, the outer diameter of the pad 4 and the sound-absorbing and friction-reducing pad B8 is larger than the inner diameter of the upper opening 11, so that during the upward movement of the stop pin 2, the pad 4 cooperates with the upper opening 11 to achieve a limiting action.

[0027] A limiting plate 5 is installed below the lower opening 12. A sound-absorbing and wear-reducing pad A7 is installed on the upper surface of the limiting plate 5. The bolt 6 is threaded through the limiting plate 5 and the sound-absorbing and wear-reducing pad A7 in sequence and then fixed to the bottom of the stop pin 2. Preferably, the outer diameter of the limiting plate 5 and the sound-absorbing and wear-reducing pad A7 is larger than the inner diameter of the lower opening 12, so that the limiting plate 5 cooperates with the lower opening 12 to limit the movement of the stop pin 2 upward.

[0028] Preferably, the compression elastic element is a compression coil spring 3, one end of which abuts against the lower surface of the pad 4, and the other end of which abuts against the upper surface of the base plate 10. The length of the stop pin 2 extending out of the upper opening 11 is less than or equal to the compression stroke of the compression elastic element (compression coil spring 3).

[0029] The working process of this utility model:

[0030] During assembly, first insert the compression coil spring 3 and the pad 4 from the side of the bracket 1, with the pad 4 abutting against the top of the compression coil spring 3, aligning the center of the opening in the pad 4 with the center of the opening at the top of the bracket 1 (i.e., the upper opening 11). Then, insert the stop pin 2 from the upper opening 11 at the top of the bracket 1. The limiting plate 5 is fixedly installed at the bottom of the stop pin 2 with bolts 6. Ensure that the stop pin 2 can extend and retract freely under vertical force. Finally, fix the assembled box-type stop mechanism to the IGV frame with bolts.

[0031] This invention features a noise-reducing and wear-absorbing pad B8 between the pad 4 and the top plate 9, which is fixedly fitted onto the stop pin 2 together with the pad 4. Simultaneously, a noise-reducing and wear-absorbing pad A7 is placed between the limiting plate 5 and the bottom plate 10, and is fixed to the bottom of the stop pin 2 together with the limiting plate 5 using bolts 6. Both the noise-reducing and wear-absorbing pads A7 and B8 are made of materials with properties such as wear resistance, impact resistance, corrosion resistance, low-temperature resistance, self-lubrication, and noise reduction.

[0032] like Figure 2 The diagram shown is a structural schematic of the stop pin 2 after it has been pressed down. At this time, the stop pin 2 is in a fully depressed state after being subjected to force. When the pressure on the stop pin 2 is removed, the housing stop mechanism will open from its original position under the restoring force of the compression coil spring 3. Figure 2 The state was restored to Figure 1 In the absence of noise-reducing and wear-reducing pads A7 and B8, the limiting plate 5 and the bottom plate 10, and the pad 4 and the top plate 9 will directly and rigidly contact each other. The addition of noise-reducing and wear-reducing pads A7 and B8 between them effectively avoids the noise of metal-on-metal contact and premature wear of the paint.

[0033] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this utility model should fall within the protection scope of the appended claims.
