Abstract
Description
Technical Field
[0001] This utility model relates to the field of excavator chassis repair technology, specifically a port excavator chassis repair tool. Background Technology
[0002] Excavating machinery is earthmoving machinery that uses a bucket to excavate materials above or below the machine's bearing surface and load them into transport vehicles or unload them into a stockpile. The materials excavated are mainly soil, coal, silt, and pre-loosened rocks and ores. Excavating machinery is divided into two categories: single-bucket excavators and multi-bucket excavators.
[0003] Excavators can also be used as transshipment tools for ship materials in ports. However, due to the limitations of the port working environment, the excavator chassis is easily damaged. Traditional maintenance equipment cannot provide lifting function and cannot lift the chassis. In addition, the high transportation cost makes it inconvenient to send the excavator back to the repair shop for maintenance. This makes it difficult for workers to carry out internal chassis maintenance. To address this, we have proposed a port excavator chassis repair tool. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Please see Figure 1-5 A port excavator chassis repair tool includes a transition plate 4, a connecting plate 1 5, a connecting plate 2 6, and a lifting device. The connecting plate 1 5 and the connecting plate 2 6 have the same structure, and both ends of the connecting plate 1 5 and the connecting plate 2 6 are provided with lifting devices. The lifting devices are provided with three sliding holes 1 8 and three sliding holes 2 12 that are equidistantly distributed at the positions corresponding to the positions of the connecting plates 1 5 and the connecting plate 2 6. The short side of the lifting device 1 is provided with a transition plate 4.
[0024] Furthermore, the lifting device consists of three parts: a rising plate 1, a lower support plate 2, and two large hydraulic rods 3. The large hydraulic rods 3 are located between the rising plate 1 and the lower support plate 2. The base of the large hydraulic rods 3 is welded to the sliding hole 12, and the hydraulic push rod of the large hydraulic rods 3 is welded to the rising plate 1.
[0025] Furthermore, the lower support plate 2 has a placement hole 11 inside. The lower support plate 2 has three connecting blocks 7 that are equidistant from the large hydraulic rod 3 at one end. The connecting blocks 7 have sliding holes 8 that cooperate with the connecting plate 5. The connecting blocks 7 have two axially symmetrical connecting holes 9 that are perpendicular to the end face of the large hydraulic rod 3. The lower support plate 2 has anti-slip protrusions 10 that are equidistant from the end face of the large hydraulic rod 3 at one end. The placement hole 11 can temporarily prevent the connecting plate 5 and the connecting plate 6 from slipping during the transfer process, increasing the space utilization rate. The anti-slip protrusions 10 can increase the friction with the ground and prevent the excavator chassis repair tool for the port from slipping.
[0026] Furthermore, a support plate 17 perpendicular to the lower support plate 2 is provided at the end of the rising plate 1 that is connected to the large hydraulic rod 3 near the transition plate 4. A mating block 18 is provided at the end of the rising plate 1 that is connected to the transition plate 4, and a mating hole 19 is provided on the mating block 18. A limiting block 13 is provided at the end of the rising plate 1 that is away from the support plate 17. An anti-slip protrusion 14 is provided at equal intervals on the end face of the rising plate 1 that is away from the large hydraulic rod 3. Two countersunk holes 15 that are axially symmetrically distributed through the rising plate 1 are provided at the position corresponding to the sliding hole 12. The countersunk holes ensure that the bolt head connecting the rising plate 1 and the connecting plate 6 does not affect the movement of the excavator, and the anti-slip protrusion 14 facilitates the movement of the excavator.
[0027] Furthermore, the transition plate 4 is provided with two axially symmetrically distributed protrusions 20 at one end corresponding to the rising plate surface 1, and a connecting rod 21 that is connected to the mating hole 19 is provided between the two protrusions 20. The end of the transition plate 4 away from the rising plate surface 1 is provided with a mating inclined plate 23, and the end face of the transition plate 4 away from the lower support plate surface 2 is provided with anti-slip protrusions 22 that are equidistantly distributed.
[0028] Furthermore, the main body of the connecting plate 5 is a rectangular plate, and the connecting plate 5 has a connecting hole 16 that is connected to the connecting hole 9 by means of an adapter bolt.
[0029] Working principle: Install the port excavator chassis repair tool correctly according to the diagram. Connect the two lifting devices equidistantly using connecting plate 5 and connecting plate 6 with matching bolts. The lifting device consists of a rising plate 1, a lower support plate 2, and two large hydraulic rods 3. The large hydraulic rods 3 are located between the rising plate 1 and the lower support plate 2. The base of the large hydraulic rod 3 is welded to the sliding hole 12, and the hydraulic push rod of the large hydraulic rod 3 is welded to the rising plate 1. A transition plate 4 is connected to the tail end of the rising plate 1. The interval between the two lifting devices can be adjusted according to the bottom tracks of the port excavator to be repaired. The end of the transition plate 4 facing away from the lifting device is aligned with the inclined plate 23 and the ground. Upon contact, the port excavator to be repaired is moved from the transition plate 4 onto two lifting devices. The upper and lower parts of the lifting devices are respectively equipped with anti-slip protrusions 14 and 10, and anti-slip protrusions 22 on the transition plate 4 to increase friction and prevent slippage, ensuring the safety of the movement process. When the excavator is moved to a suitable position, the large hydraulic rod 3 inside the lifting device is activated, causing the rising plate 1 to slowly rise, thus lifting the port excavator to be repaired. Therefore, the maintenance personnel can carry out maintenance work on the bottom of the port excavator. After the maintenance is completed, when the excavator chassis repair kit needs to be moved away, the connecting plate 5 and the connecting plate 6 can be placed in the placement hole 11 on the lower support plate 2 for easy transportation.
[0030] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
