Abstract
Description
Technical Field
[0001] This utility model relates to the field of disassembly and maintenance structure technology, specifically a quick disassembly and maintenance structure for the chassis of a walking excavator. Background Technology
[0002] Walking excavators are all-terrain multi-functional excavators, often called "spider excavators" or "mountain excavators." They are an extension and supplement to the functions of tracked excavators and are particularly suitable for working environments with complex terrain and confined spaces. To facilitate disassembly and maintenance, walking excavator chassis are equipped with bolted cover plates, which can be removed for inspection and operation.
[0003] In existing technologies, the cover plates of walking excavator chassis are typically installed and fixed using multiple sets of bolts. Disassembling and maintaining the chassis requires repeatedly tightening these bolts to remove the cover plates, making the process cumbersome. Furthermore, the loosened bolts are prone to being lost, affecting subsequent use. Therefore, we propose a quick-disassembly and maintenance structure for walking excavator chassis. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a quick disassembly and maintenance structure for the chassis of a walking excavator. This solves the problem that the cover plates of walking excavator chassis are usually installed and fixed with multiple sets of bolts. When disassembling and maintaining the chassis, it is necessary to tighten the bolts multiple times to remove the cover plates, which is a cumbersome operation. In addition, the unscrewed bolts are easy to be lost, which affects subsequent use.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A quick-release and maintenance structure for a walking excavator chassis includes a mounting plate. The mounting plate has symmetrically shaped grooves inside, with sliding rods slidably connected within each groove. Limit blocks are fixedly connected at equal intervals to one side of each sliding rod. A drive shaft is symmetrically rotatably connected inside the mounting plate. A turntable is fixedly connected to one end of the drive shaft, and a push rod is fixedly connected to the outer side of the turntable. A connecting rod is fixedly connected to one side of each sliding rod, and a sliding frame is fixedly connected to one end of the connecting rod. The sliding frame has a transmission groove inside that cooperates with the push rod. The mounting plate has a cover plate inside, with limit grooves at equal intervals inside that cooperate with the limit blocks. In use, the rotation of the drive shaft drives the push rod to rotate, causing it to engage with the transmission grooves. This causes the push rod to press against and slide the sliding frame. The sliding frame, via the connecting rod, moves the sliding rod, which in turn moves the limit blocks into or out of the limit grooves, facilitating quick disassembly and assembly of the cover plate.
[0007] Preferably, the sliding groove is fixedly connected with limit rods at equal intervals inside, and the sliding rod is slidably connected to the limit rods. The movement of the sliding rod can be limited by the setting of the limit rods to prevent deviation.
[0008] Preferably, the outer side of the cover plate is threaded with an observation cover at equal intervals, which facilitates pre-observation during maintenance.
[0009] Preferably, a fixing rod is fixedly connected inside the mounting plate, and the connecting rod is slidably connected to the fixing rod. The fixing rod can limit the movement of the connecting rod and prevent deviation.
[0010] Preferably, a gear is fixedly connected to the outer side of the drive shaft, and a first knob is fixedly connected to one end of one of the drive shafts. The first knob drives one of the drive shafts to rotate, and the gear on the outer side of one drive shaft drives the gear on the outer side of another drive shaft to rotate, thereby driving the other drive shaft to rotate.
[0011] Preferably, a slide rod is fixedly connected inside the mounting plate, and an adjusting block is slidably connected to the outside of the slide rod. A limiting tooth is fixedly connected to one side of the adjusting block, and an external gear ring that cooperates with the limiting tooth is fixedly connected to the outside of the transmission shaft. The movement of the adjusting block drives the limiting tooth to move, so that the limiting tooth and the external gear ring fit together, thereby locking the position of the transmission shaft and preventing reverse rotation.
[0012] Preferably, the mounting plate has a threaded rod internally connected to it, the threaded rod is rotatably connected to the adjusting block, and a second knob is fixedly connected to one end of the threaded rod. The second knob drives the threaded rod to rotate, and the rotation of the threaded rod drives the adjusting block to move.
[0013] This utility model provides a quick-disassembly and maintenance structure for the chassis of a walking excavator. Compared with the prior art, it has the following advantages:
[0014] 1. The quick disassembly and maintenance structure for the walking excavator chassis enables the quick disassembly and assembly of the cover plate by setting up a drive shaft, turntable, push rod, transmission groove, sliding frame, connecting rod, sliding rod, limit block and limit groove, which facilitates the quick disassembly and maintenance of the walking excavator chassis.
[0015] 2. The quick-release and maintenance structure of the walking excavator chassis, through the setting of threaded rods, adjusting blocks, limit teeth and external gear ring, realizes the function of locking the position of the drive shaft, preventing the drive shaft from reversing and facilitating use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0025] Please see Figures 1 to 7 This utility model provides a technical solution:
[0026] The walking excavator chassis quick-release and maintenance structure includes a mounting plate 1. The mounting plate 1 has symmetrically symmetrically arranged grooves 8. A sliding rod 7 is slidably connected inside the grooves 8. Limit blocks 6 are fixedly connected at equal intervals to one side of the sliding rod 7. A drive shaft 21 is symmetrically rotatably connected inside the mounting plate 1. A turntable 10 is fixedly connected to one end of the drive shaft 21. A push rod 15 is fixedly connected to the outer side of the turntable 10. A connecting rod 12 is fixedly connected to one side of the sliding rod 7. A sliding frame 11 is fixedly connected to one end of the connecting rod 12. The sliding frame 11 has internal openings that connect with the push rod 15. The transmission groove 13 used in conjunction with the rod 15 has a cover plate 2 inside the mounting plate 1. The cover plate 2 has equidistant limiting grooves 23 that cooperate with the limiting block 6. In use, the rotation of the transmission shaft 21 drives the push rod 15 to rotate, so that the push rod 15 cooperates with the transmission groove 13. This causes the push rod 15 to press and drive the sliding frame 11 to slide. The sliding frame 11 drives the sliding rod 7 to move through the connecting rod 12. The sliding rod 7 drives the limiting block 6 to move into or out of the limiting groove 23, which facilitates the quick assembly and disassembly of the cover plate 2.
[0027] Furthermore, the slide groove 8 is fixedly connected with limit rods 9 at equal intervals inside, and the sliding rod 7 is slidably connected with the limit rods 9. The movement of the sliding rod 7 can be limited by the setting of the limit rods 9 to prevent deviation.
[0028] Furthermore, the outer side of the cover plate 2 is threaded with an observation cover 3 at equal intervals, which facilitates pre-observation during maintenance.
[0029] Furthermore, a fixing rod 14 is fixedly connected inside the mounting plate 1, and the connecting rod 12 is slidably connected to the fixing rod 14. The fixing rod 14 can limit the movement of the connecting rod 12 to prevent displacement.
[0030] Furthermore, a gear 16 is fixedly connected to the outer side of the drive shaft 21, and a first knob 4 is fixedly connected to one end of one of the drive shafts 21. The first knob 4 drives one of the drive shafts 21 to rotate, and the gear 16 on the outer side of one of the drive shafts 21 drives the gear 16 on the outer side of the other drive shaft 21 to rotate, thereby driving the other drive shaft 21 to rotate.
[0031] Furthermore, a slide rod 19 is fixedly connected inside the mounting plate 1, and an adjusting block 20 is slidably connected to the outside of the slide rod 19. A limiting tooth 17 is fixedly connected to one side of the adjusting block 20, and an external gear ring 22 that cooperates with the limiting tooth 17 is fixedly connected to the outside of the drive shaft 21. The movement of the adjusting block 20 drives the limiting tooth 17 to move, so that the limiting tooth 17 and the external gear ring 22 fit together, thereby locking the position of the drive shaft 21 and preventing reverse rotation.
[0032] Furthermore, the mounting plate 1 has a threaded rod 18 internally connected to the threaded rod 18, which is rotatably connected to the adjusting block 20. One end of the threaded rod 18 is fixedly connected to a second knob 5, which drives the threaded rod 18 to rotate, and the rotation of the threaded rod 18 drives the adjusting block 20 to move.
[0033] When disassembling and maintaining the chassis of the walking excavator, rotate the threaded rod 18. The rotation of the threaded rod 18 causes the adjusting block 20 to move. The sliding rod 19 limits the movement of the adjusting block 20 to prevent deviation. The adjusting block 20 causes the limiting tooth 17 to move away from the outer gear ring 22, allowing the first knob 4 to be rotated. The first knob 4 causes one of the drive shafts 21 to rotate. One drive shaft 21 drives the outer gear 16 of another drive shaft 21 to rotate, thereby causing the other drive shaft 21 to rotate. The drive shaft 21 drives the push rod 15 to rotate through the turntable 10, causing the push rod 15 to engage with the transmission groove 13. This causes the push rod 15 to press and drive the sliding frame 11 to slide. The sliding frame 11 drives the sliding rod 7 to move through the connecting rod 12. The sliding rod 7 causes the limiting block 6 to move away from the limiting groove 23, allowing the cover plate 2 to be removed. The operation is convenient and easy to use.
