Description

Technical Field

[0001] This utility model relates to the field of ship loaders, and in particular to a distributed ship loader traveling wheel set. Background Technology

[0002] Ship loaders are large bulk material handling machines used at bulk cargo terminals for loading onto ships. Their main function is to transport bulk materials from the shore to the vessel via a swing arm integrated with a conveyor belt. Ship loaders have several feeding methods. One type has the hopper at the outer end, where trucks dump cargo from the road surface into the hopper. Another type has the hopper at the belly of the ship loader, such as the Chinese patent CN216548660U horizontal transfer ship loader. For the structure with the hopper at the belly, trucks need to drive onto the ship loader via a ramp. Due to the weight of the trucks and the slope of the ramp, the trucks exert a significant impact on the ship loader. Additionally, the dumping of cargo also generates considerable impact force.

[0003] Ship loaders typically have only a few wheels in direct hard contact with the guide rails, resulting in concentrated stress. Frequent loading and unloading operations can cause irreversible damage to the guide rails and wheel surfaces. Utility Model Content

[0004] This invention provides a distributed ship loader traveling wheel assembly, which solves the problem of traditional ship loaders having few traveling wheels and the impact force damaging the traveling wheels and guide rail surfaces during loading and unloading.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a distributed ship loader traveling wheel assembly, including multiple articulated arms, with adjacent articulated arms alternately hinged at their ends and middle to form a scissor-type articulated telescopic structure. The end hinge points of the scissor-type articulated telescopic structure are provided with multiple wheel-to-wheel connecting plates, which are rotatable. Each wheel-to-wheel connecting plate has rotatable traveling wheels at at least at both ends. It also has a middle connecting block for the articulated arm, with a first round hole and a first oblong hole at both ends. The scissor-type articulated telescopic structure includes a first middle hinge point and a second middle hinge point. The first middle hinge point is hinged to the first round hole of the middle connecting block for the articulated arm. The second middle hinge point is provided with a second pin, which slides in the first oblong hole. The middle connecting block for the articulated arm is used to connect with the ship loader base frame. It also has a tension spring, with both ends of the tension spring connected to two end hinge points along the length of the traveling track on the scissor-type articulated telescopic structure.

[0006] In the preferred embodiment, a snap-fit ​​slider is also provided. The middle connecting block of the hinge arm is provided with multiple connecting blocks. The middle connecting block of the hinge arm is provided with a sliding groove. The snap-fit ​​slider is provided with a snap-fit ​​part. The snap-fit ​​part is slidably snap-fitted with the sliding groove. The middle part of the snap-fit ​​slider is rotatably connected to the ship loader base frame.

[0007] In the preferred embodiment, a first pin is provided at the hinge point in the middle of the scissor-type telescopic structure. The first pin passes through the first round hole in the connecting block in the middle of the hinge arm, and a tension spring hanging hole is provided at the end of the first pin.

[0008] In a preferred embodiment, the snap-fit ​​slider has a clearance portion on the side near the middle connecting block of the hinge arm.

[0009] In the preferred embodiment, the two ends of the snap-fit ​​slider are respectively provided with a second round hole and a second oblong hole, and a second pin is provided in the pin hole. The second round hole and the second oblong hole are used to connect with the second pin.

[0010] The beneficial effects of this utility model are as follows: replacing a single large traveling wheel with multiple small traveling wheels increases the contact points with the guide rail surface, disperses pressure, and reduces impact damage; adopting a dynamic abutment scissor-type articulated telescopic structure, utilizing the telescopic process to weaken the impact force and lengthen the force arm, effectively preventing the ship loader from overturning due to uneven load; the scissor-type articulated telescopic structure has good expandability, and the number of wheel sets can be increased according to the length of the ship loader.

[0020] like Figure 1-7 In a distributed ship loader traveling wheel assembly, there are multiple articulated arms 3. The ends and middle of adjacent articulated arms 3 are alternately hinged to form a scissor-type articulated telescopic structure. The end hinge points of the scissor-type articulated telescopic structure are provided with multiple wheel connecting plates 2. The wheel connecting plates 2 are rotatable. At least two ends of the wheel connecting plates 2 are provided with rotatable traveling wheels 1. There is also a middle connecting block 4 of the articulated arm. The two ends of the middle connecting block 4 of the articulated arm are respectively provided with a first round hole and a first waist-shaped hole 402. The scissor-type articulated telescopic structure includes a first middle hinge point and a second middle hinge point. The first middle hinge point is hinged to the first round hole of the middle connecting block 4 of the articulated arm. The second middle hinge point is provided with a second pin. The second pin slides in the first waist-shaped hole 402. The middle connecting block 4 of the articulated arm is used to connect with the ship loader base frame 10. There is also a tension spring 7. The two ends of the tension spring 7 are respectively connected to the two end hinge points of the scissor-type articulated telescopic structure along the length direction of the traveling track 11.

[0021] The middle part of the pin hole 403 can be rotatably connected to the ship loader base frame 10. The set of traveling wheels can be installed on the upper and lower parts of the traveling rail 11 respectively. Since the middle connecting block 4 of the hinged arm is hinged and the wheel connecting plate 2 can rotate, it can be ensured that each traveling wheel 1 can abut against the traveling rail 11 to form a stable and uniform force.

[0022] One of the walking wheels 1 is equipped with a walking wheel drive motor 9, which serves as the driving force source.

[0023] Multiple tension springs 7 can be installed and hung on the holes at the ends of the tension spring mounting shafts 6, hooking onto the end of the articulated arm 3 where the traveling wheels 1 are not installed. Due to the tension of the tension springs 7, the scissor-type articulated telescopic structure is in its shortest state under normal conditions. When the truck impacts the ship loader, taking the wheel set against the lower side of the traveling rail 11 as an example, when the upward tension increases, the tension springs 7 are stretched open, the distance between the connecting block 4 in the middle of the articulated arm and the lower side of the traveling rail 11 becomes shorter, and the distance between the wheel connecting plates 2 increases. In other words, the spacing between the traveling wheels 1 becomes larger, making the force points more dispersed. By installing the first waist-shaped holes 402 in the direction towards both ends of the ship loader base frame 10, the traveling wheels 1 will extend towards the two outer ends of the ship loader base frame 10, that is, the force points extend outwards, the lever arm increases, effectively counteracting the overturning moment, making the ship loader more stable. In addition, due to the presence of tension spring 7, the impact of external forces is flexibly resolved by the scissor action when the articulated telescopic structure extends and retracts, and the vibration is weakened when loading and unloading goods and when moving, making the operation more stable.

[0024] In the preferred embodiment, a snap-fit ​​slider 8 is provided, and there are multiple connecting blocks 4 in the middle of the hinge arm. The connecting blocks 4 in the middle of the hinge arm are provided with sliding grooves 401. The snap-fit ​​slider 8 is provided with a snap-fit ​​part 801. The snap-fit ​​part 801 is slidably snap-fitted with the sliding grooves 401. The middle part of the snap-fit ​​slider 8 is rotatably connected to the ship loader base frame 10.

[0025] The traveling wheel 1 can be set in many places. The two central hinge points are connected by a central connecting block 4 of a hinge arm. Multiple central connecting blocks 4 of hinge arms are connected by a snap-fit ​​slider 8. The snap-fit ​​slider 8 has a pin hole in the middle. The ship loading machine base frame 10 is provided with an ear seat. The ear seat is inserted into the pin hole of the snap-fit ​​slider 8 to rotate the pin.

[0026] In the preferred embodiment, a first pin 5 is provided at the hinge point in the middle of the scissor-type telescopic structure. The first pin 5 passes through the first round hole of the connecting block 4 in the middle of the hinge arm, and a tension spring hanging hole 504 is provided at the end of the first pin 5.

[0027] The first pin 5 is provided with a stop part 501, a rotating shaft part 502 and a screw part 503, and is used as a rotating pin at the middle hinge point.

[0028] The tension spring mounting hole 504 is used to install the tension spring 7. In addition to the free end of the hinge arm 3, the tension spring 7 is also installed in the middle of the hinge arm 3, which can further increase the contraction force of the scissor hinge telescopic structure, improve the overall spring stiffness, and make it able to resist greater impact forces.

[0029] In the preferred embodiment, the snap-fit ​​slider 8 is provided with a clearance portion 802 on the side near the middle connecting block 4 of the hinge arm.

[0030] The clearance part 802 is used to avoid the tension spring 7 mounted on the first pin 5.

[0031] In a preferred embodiment, the two ends of the snap-fit ​​slider 8 are respectively provided with a second round hole and a second oblong hole 803, and a second pin 804 is provided in the pin hole 403. The second round hole and the second oblong hole 803 are used to connect with the second pin 804.

[0032] The second pin 804 of the connecting block 4 in the middle of one hinge arm is rotatably sleeved with the second round hole of the locking slider 8, and the second pin 804 of the connecting block 4 in the middle of the other hinge arm slides in the second oblong hole 803. The second oblong hole 803 limits the movement direction of the second pin 804.

[0033] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
