Description

Technical Field

[0001] This utility model relates to the field of chassis walking technology for grabbers, specifically a chassis walking device for wheeled grabbers at inland river terminals. Background Technology

[0002] Due to their high efficiency, inland river wharf grabbers have great development prospects. Due to the grabbing tonnage of the grabber and the eccentric loading state, steel rails are set on the river side to travel along the riverbank; while on the other side, polyurethane rubber rollers mainly travel directly on the concrete ground.

[0003] Due to the difficulty in controlling the level of concrete surfaces during port and dock construction, level differences can exceed 100mm. In such cases, horizontal rollers often experience lifting off the ground and become unable to bear the load. Figure 5 In the diagram, 3 represents an existing polyurethane rubber flat wheel walking device, such as... Figure 6 As shown in Figure 33, the existing polyurethane rubber flat wheel is a type of wheel. Because there are steel rails laid on the river side, the walking device on the river side will not be suspended in mid-air, and the steel rails can also provide strong support load for the steel wheels. On the roadside, since the polyurethane rubber flat wheel walks on the concrete ground, if there is a large drop in the concrete ground, the rubber flat wheel will be suspended in mid-air in some places, which will affect the safe operation of the equipment.

[0004] To address this, we provide a chassis-mounted traveling device for a wheeled grabber at an inland river terminal. Utility Model Content

A central mounting pin is installed near one end of the rubber wheel mounting bracket, penetrating the bracket and extending to its exterior. A bearing, rotatably connected to the central mounting pin, is mounted on the inner wall of the rubber wheel mounting bracket and located on the surface of the central mounting pin.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6 The chassis walking device of the inland river terminal wheeled grab reclaimer includes a chassis walking mechanism 4, which includes a mounting bracket 41. Movable support frames 42 are fixedly connected to the front and rear sides of the bottom of the mounting bracket 41. Rollable polyurethane rubber rollers 49 are provided below the mounting bracket 41.

[0020] It also includes rubber wheel mounting brackets 44, two of which are respectively located on the front and back of the polyurethane rubber roller 49. Both the front and back of the polyurethane rubber roller 49 are fixedly connected to a rubber wheel center mounting pin 45. One end of the rubber wheel center mounting pin 45 near the rubber wheel mounting bracket 44 passes through the rubber wheel mounting bracket 44 and extends to its exterior. A bearing, rotatably connected to the rubber wheel center mounting pin 45, is fixedly connected to the inner wall of the rubber wheel mounting bracket 44 on the surface of the rubber wheel center mounting pin 45. A support frame 42 is fixedly connected to a support frame mounting pin 43 on one side near the rubber wheel mounting bracket 44. One end of the support frame mounting pin 43 near the rubber wheel mounting bracket 44 passes through the rubber wheel mounting bracket 44 and extends to its exterior. A bearing, rotatably connected to the inner wall of the rubber wheel mounting bracket 44 on the surface of the support frame mounting pin 43, is fixedly connected to... The bearing is rotatably connected to the support frame mounting pin 43. A balancing cylinder 47 is provided on both the front and back of the polyurethane rubber roller 49. A first balancing cylinder mounting pin 46 is fixedly connected to the output end of the balancing cylinder 47. One end of the first balancing cylinder mounting pin 46 near the rubber wheel mounting bracket 44 passes through the rubber wheel mounting bracket 44 and extends to its outside. A bearing rotatably connected to the first balancing cylinder mounting pin 46 is fixedly connected to the inner wall of the rubber wheel mounting bracket 44 and located on the surface of the first balancing cylinder mounting pin 46. A second balancing cylinder mounting pin 48 is fixedly connected to the top of the balancing cylinder 47. The side of the second balancing cylinder mounting pin 48 near the support frame 42 passes through the support frame 42 and extends to its outside. A bearing rotatably connected to the second balancing cylinder mounting pin 48 is fixedly connected to the inner wall of the support frame 42 and located on the surface of the second balancing cylinder mounting pin 48.

[0021] Furthermore, such as Figure 5-6 The riverside walking wheel mechanism 2 rolls on the riverside walking rail 1, which is laid on the riverside. The polyurethane walking rubber flat wheel 33 on the roadside polyurethane rubber flat wheel walking mechanism 3 travels on the concrete ground. The polyurethane walking rubber flat wheel 33 is mounted on the walking device frame 32, which is mounted on the walking device support frame 31.

[0022] Furthermore, the chassis walking mechanism 4 can be installed on the walking device frame 32 and replaced with the polyurethane walking rubber flat wheel 33 in the prior art. This can compensate for the unevenness of the concrete ground and keep the polyurethane rubber roller 49 under stress.

[0023] Furthermore, the hydraulic power load balancing and support functions are achieved through the equalization cylinder 47. It uses a hydraulic control system to precisely control the hydraulic flow, ensuring load balance under different operating conditions, thereby maintaining the stable operation of the mechanical equipment.

[0024] By cooperating with the mounting bracket 41, support frame 42, support frame mounting pin 43, rubber wheel mounting bracket 44, rubber wheel center mounting pin 45, first equalizing cylinder mounting pin 46, equalizing cylinder 47, second equalizing cylinder mounting pin 48, and polyurethane rubber roller 49, the polyurethane rubber roller 49 can always maintain contact with the ground. Even when there is a large drop in the concrete ground, the wheel can still make contact with the ground and provide balanced load support, ensuring stable movement of the equipment and providing stable ground support for the process of grabbing materials. Moreover, the hydraulic system of the grabbing machine itself can be used, without the need for an additional hydraulic system.

[0025] In use, the balancing cylinder 47 is activated. The extension and retraction of the balancing cylinder 47 causes the polyurethane rubber roller 49 to move up and down, achieving the following: Figure 2-4 This ensures that the polyurethane rubber roller 49 is always in contact with the ground, as shown in the diagram.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
