[0002] The travel motor is an important component of the excavator chassis. To prevent it from being bumped or covered in dust, it is installed in a sealed motor bracket.
[0003] Typically, an inspection port is installed inside the travel motor, along with an inspection cover, to facilitate future maintenance. Currently, most travel motor brackets on the market have their inspection covers fixed with bolts. During maintenance, they are usually disassembled by a single person, and there is a lack of handles, posing a risk that the cover may fall and injure maintenance personnel.
[0004] Therefore, the inventors sought to solve the problem of designing a structure with a hinged connection that does not require complete disassembly, a handle for easy operation, and a double-cover design. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide an integrated control system for wheeled excavators that enables hinged connections to be made without complete disassembly, features a handle for easy operation, and includes a double-cover design.
[0006] The technical solution adopted by this invention to solve its technical problem is: a maintenance cover plate structure for an excavator travel motor bracket, which is installed on the travel motor bracket of an excavator. One end of the travel motor bracket is provided with an opening and a base plate is provided at the edge of the opening. A first hinge is bolted to the end face of the base plate. The base plate is hinged to a first cover plate through the first hinge. Four evenly distributed first limiting ears are provided at the corners of the inner sidewall of the travel motor bracket. A first handle is provided on the end face of the first cover plate. A small maintenance port is provided on the cross-section of the first cover plate and on the side of the first handle. A second hinge is bolted to the edge of the small maintenance port and a second cover plate is connected through the second hinge. Four evenly distributed second limiting ears are provided at the corners of the inner sidewall of the small maintenance port. A second handle is provided on the end face of the second cover plate.
[0007] Furthermore, the first limiting ear plate is provided with a first threaded hole, and the first cover plate is provided with a stepped hole that is positioned opposite to the first threaded hole.
[0008] Furthermore, the second limiting ear plate is provided with a second threaded hole, and the second cover plate is provided with a mounting hole that is opposite to the position of the first threaded hole.
[0009] Furthermore, a safety plate is connected to the upper outer wall of the walking motor bracket.
[0010] Furthermore, the safety plate has a perforation, and a chain passes through the inside of the perforation. The chain passes through a stepped hole adjacent to the first cover plate when it is open.
[0011] Furthermore, the two ends of the chain are connected by a fastener.
[0012] Furthermore, the connecting buckle includes a U-shaped body, with end rings at both ends of the U-shaped body. A limit bolt passes through the inner side of the end ring, and a limit nut is threaded on the outer side of the tail of the limit bolt.
[0013] The beneficial effects of this utility model are: 1. This utility model adopts a structure design of double hinges and double cover plates. Each cover plate is equipped with a handle. The second cover plate is used for routine maintenance and observation. If a major operation is required, the first cover plate can be opened. At the same time, a safety plate and a chain are used to fasten one end of the first cover plate in the open state to prevent the hinge from being damaged or the cover plate from falling off suddenly in case of accident. This realizes the function of the hinge connection without complete disassembly, with handles for easy operation and double cover plate design. Attached Figure Description

Detailed Implementation
[0017] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0018] See Figures 1 to 2The diagram shows the structure of the present invention and the second cover plate 7. A maintenance cover plate structure for an excavator travel motor bracket 1 is provided on the travel motor bracket 1 of the excavator. One end of the travel motor bracket 1 is provided with an opening and a base plate is provided at the edge of the opening. A first hinge 15 is bolted to the end face of the base plate. The base plate is hinged to a first cover plate 4 through the first hinge 15. A first handle 6 is provided on the end face of the first cover plate 4. After the first cover plate 4 is opened, the travel motor will be fully exposed to the field of vision, which is convenient for workers to carry out major repairs, maintenance, replacement and other operations.
[0019] Four evenly distributed first limiting ear plates 2 are provided at the corners of the inner side wall of the walking motor bracket 1. The first limiting ear plates 2 are provided with first threaded holes 3. The first cover plate 4 is provided with stepped holes 5 that are positioned opposite to the first threaded holes 3. When the first cover plate 4 is not opened, the first cover plate 4, the first limiting ear plates 2, and the walking motor bracket 1 are generally fixed by bolts.
[0020] A small inspection port is provided on the cross-section of the first cover plate 4 and on the side of the first handle 6. A second hinge 8 is bolted to the edge of the small inspection port and a second cover plate 7 is connected to it. Four evenly distributed second limiting ears 10 are provided at the corners of the inner wall of the small inspection port. A second handle 9 is provided on the end face of the second cover plate 7. A second threaded hole 11 is provided on the second limiting ears 10. An installation hole is provided on the second cover plate 7 that is opposite to the position of the first threaded hole 3. If routine inspection and maintenance are required, the second cover plate 7 can be opened. The opening operation and operation intensity of the second cover plate 7 are less than those of the first cover plate 4. Opening the second cover plate 7 can also provide the operator with a sufficient observation window. The operator can observe the operation of the equipment and perform some simple maintenance through the window, thereby saving operation time and improving efficiency.
[0021] A safety plate 12 is connected to the upper outer wall of the travel motor bracket 1. A through hole is provided on the safety plate 12, and a chain 13 is installed through the inner side of the through hole. The chain 13 passes through a stepped hole 5 on the first cover plate 4 when it is open. The two ends of the chain 13 are connected by a connecting buckle 14. The connecting buckle 14 includes a U-shaped body, and both ends of the U-shaped body are provided with end rings. A limit bolt is installed through the inner side of the end ring, and a limit nut is provided on the outer thread of the tail of the limit bolt. In some large excavators, the cover plate of the travel motor bracket 1 is heavy. As the usage time increases, the first hinge 15 may be damaged. When long-term inspection and maintenance are required, the first cover plate 4 must be kept open for a long time, which will increase the burden on the first hinge 15. At this time, the chain 13 passes through the stepped hole 5 on the first cover plate 4 to add a safety layer to the first cover plate 4, preventing it from falling suddenly due to other reasons and increasing the safety factor.
[0022] This utility model adopts a structure design with double hinges and double cover plates. Each cover plate is equipped with a handle. The second cover plate 7 is used for routine maintenance and observation. If a major operation is required, the first cover plate 4 can be opened. At the same time, a safety plate 12 and a chain 13 are used to fasten one end of the first cover plate 4 in the open state to prevent the hinge from being damaged or the cover plate from suddenly falling off in case of accident. This realizes the function of the hinge connection without complete disassembly, with handles for easy operation and double cover plate design.
