Technical Field

[0001] The utility model belongs to the technical field of tension springs, and particularly relates to a crawler tension spring for an anti-derailment excavator. Background Technique

[0002] An excavator, also known as an excavation machine or a power shovel, is an earthmoving machine used to excavate materials above or below the machine surface. It is mainly used to excavate materials such as soil, coal, sediment, and pre-loosened soil and rock. In recent years, with the development of construction machinery, excavators have been more and more widely used and play an important role in engineering construction.

[0003] After long-term use, the elasticity of the crawler tension spring will decrease, unable to meet the actual buffering requirements. The existing tension springs are not convenient to replace, which will not only lead to a weakening of the excavator's walking ability, but also increase the complexity and cost of maintenance, and may cause more serious mechanical failures, ultimately affecting work efficiency and safety.

Through the cooperation of the fixing component 8 and the retaining ring 4, it is convenient to clamp the moving plate 5 on the surface of the cylinder barrel 1 to realize the fixation of the moving plate 5.

[0029] Embodiment 2

[0030] Referring to Figure 3 , this is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0031] In this embodiment, a fixing assembly 8 is arranged on the outer side of the cylinder barrel 1. The fixing assembly 8 includes a lower fixing block 801, a connecting groove 802, a first connecting block 803, an upper fixing block 804, a clamping column 805, a second connecting block 806, a threaded hole 807 and a fixing bolt 808. The lower fixing block 801 is fixedly installed on the outer side of the cylinder barrel 1. The connecting groove 802 is opened inside the lower fixing block 801. Both first connecting blocks 803 are fixedly installed on the outer side of the lower fixing block 801. The upper fixing block 804 is installed on the top of the upper fixing block 804. The clamping column 805 is fixedly installed at the bottom of the upper fixing block 804. Both second connecting blocks 806 are fixedly installed on the outer side of the upper fixing block 804. The threaded hole 807 is arranged inside the first connecting block 803 and the second connecting block 806. The fixing bolt 808 is installed inside the threaded hole 807.

[0033] Embodiment 3

[0034] Referring to Figure 4 and 5 , this is the third embodiment of the present utility model, and this embodiment is based on the previous two embodiments.

[0035] In this embodiment, a fixing frame 9 is fixedly installed at one end of the cylinder barrel 1. A pressing plate 10 is bolted to the side of the fixing frame 9. A through groove 11 is arranged inside the pressing plate 10. A tension spring body 12 is arranged between the moving plate 5 and the pressing plate 10. An oil inlet pipe 13 and an oil outlet pipe 14 are arranged on the outer side of the cylinder barrel 1. External threaded pipes 15 are arranged on the outer sides of the oil inlet pipe 13 and the oil outlet pipe 14. An internally threaded sealing cap 16 is installed on the outer side of the external threaded pipe 15. A connecting bracket 17 is fixedly installed on the side of the fixing frame 9. A guide wheel 18 is arranged inside the connecting bracket 17. A crawler card slot 19 is arranged on the outer side of the guide wheel 18.

[0036] As Figure 4 and 5 shown, the cylinder barrel 1 can be refueled through the oil inlet pipe 13, and the cylinder barrel 1 can be drained through the oil outlet pipe 14. Through the cooperation of the external threaded pipe 15 and the internally threaded sealing cap 16, the oil inlet pipe 13 and the oil outlet pipe 14 are sealed.

[0037] During use, it is slidably connected through the inner wall of the sealing ring 3 and the surface of the slide bar 2, so that the total length of the cylinder barrel 1 and the slide bar 2 can be changed, thereby adjusting the tension of the crawler. The cylinder barrel 1 can be refueled through the fuel inlet pipe 13, and the cylinder barrel 1 can be drained through the fuel outlet pipe 14. When the tension spring body 12 needs to be replaced, first remove the fixing component 8, move the fixing bolt 808 out of the threaded hole 807, move the upper fixing block 804 upward so that the clamping column 805 disengages from the connection groove 802, and then remove the bolts fixing the fixing frame 9 and the pressing plate 10. By pushing the pressing plate 10 to drive the tension spring body 12 to move, and at the same time sliding out the moving plate 5, the tension spring body 12 can be removed. Slide the new pressing plate 10, tension spring body 12 and moving plate 5 onto the surface of the cylinder barrel 1. Fix the pressing plate 10 to the side of the fixing frame 9 with bolts. Through the cooperation of the fixing component 8 and the retaining ring 4, it is convenient to clamp the moving plate 5 on the surface of the cylinder barrel 1 to realize the fixation of the moving plate 5, so that the tension spring body 12 is installed inside the device, improving the working efficiency.

[0038] To sum up: Through the setting of the fixing component 8, it is convenient to replace the tension spring body 12, solving the problem that the existing tension spring for excavators is not convenient to replace. First, remove the fixing component 8, then remove the bolts fixing the fixing frame 9 and the pressing plate 10. By pushing the pressing plate 10 to drive the tension spring body 12 to move, and at the same time sliding out the moving plate 5, the tension spring body 12 can be removed. Through the cooperation of the fixing component 8 and the retaining ring 4, it is convenient to clamp the moving plate 5 on the surface of the cylinder barrel 1 to realize the fixation of the moving plate 5. By fixing the pressing plate 10 to the side of the fixing frame 9 with bolts, the tension spring body 12 is installed inside the device, improving the working efficiency.
