[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0025] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0026] Example

[0027] See also Figures 1 to 4 As shown, this embodiment provides a crawler beam 2, including a tensioning cylinder 22, a tensioning spring 21, a beam body 23 and a device 1 for supporting the tensioning spring. The beam body 23 is hollow and has a receiving cavity 231, and the receiving cavity 231 is provided with a tensioning spring 21, and the tensioning spring 21 elastically abuts against the tensioning cylinder 22.

[0028] The device 1 for supporting the tension spring includes a fixing block 11 and a supporting block 12. The supporting block 12 is disposed in the accommodating cavity 231. One end of the fixing block 11 is fixedly connected to the supporting block 12, and the other end extends to be fixedly connected to the beam body 23. A through hole 232 is opened at the bottom of the beam body 23. The through hole 232 is connected to the accommodating cavity 231. The supporting block 12 is disposed near the through hole 232.

[0029] The fixed block 11 is used to connect the beam body 23, and the support block 12 is fixedly connected to the fixed block 11. The support block 12 is arranged at the bottom of the tension spring 21. The surface of the support block 12 is recessed to form a groove 121. The groove 121 corresponds to the circumference of the tension spring 21, and the groove 121 extends along the expansion and contraction direction of the tension spring 21.

[0030] The crawler beam 2 provided in this embodiment is provided with a device 1 for supporting the tension spring in the accommodating cavity 231, and the support block 12 is provided at a position close to the through hole 232 to prevent the tension spring 21 from falling into the through hole 232 during disassembly or installation, thereby affecting the working efficiency. The device 1 for supporting the tension spring fixes the support block 12 to the bottom of the tension spring 21 through the fixing block 11, and the support block 12 corresponds to the circumference of the tension spring 21 through the groove 121 to stably support the tension spring 21. When disassembling or installing the tension spring 21, the tension spring 21 is extended and retracted along the groove 121 to reduce the gravity of the tension spring 21 affecting the efficiency of disassembly or installation.

[0031] In a possible implementation manner, the groove 121 cooperates with the circumferential surface of the tension spring 21 , and the tension spring 21 is movably disposed in the groove 121 .

[0032] In this embodiment, when the tension spring 21 is in working state, the circumference of the tension spring 21 is in clearance with the groove 121, and the tension spring 21 is extended and retracted along the extension direction of the groove 121 to elastically support the track. When the tension spring 21 is disassembled, the tension spring 21 is separated from the tension cylinder 22. Under the action of gravity, the tension spring 21 may fall to the surface of the groove 121. At this time, the support block 12 supports the tension spring 21 to prevent the tension spring 21 from falling into the through hole 232 of the beam body 23 or other positions of the beam body 23. When the tension spring 21 is installed, the tension spring 21 is placed in the groove 121, and the tension spring 21 moves along the groove 121 and is installed to the tension cylinder 22. The groove 121 is used to support and guide the tension spring 21.

[0033] In a possible implementation manner, the groove 121 extends along the circumference of the tension spring 21 , and the tension spring 21 is accommodated in the groove 121 .

[0034] In this embodiment, both ends of the groove 121 along the width direction extend to the circumference of the tension spring 21. When the tension spring 21 is installed, the groove 121 is used to reduce the displacement of the tension spring 21 along the width direction, and the groove 121 supports the tension spring 21. The tension spring 21 moves along the groove 121 and is installed to the tension cylinder 22. When the tension spring 21 is removed, the groove 121 is used to reduce the displacement of the tension spring 21 along the width direction, and the groove 121 supports the tension spring 21. The tension spring 21 moves along the groove 121 and is separated from the tension cylinder 22.

[0035] In a possible implementation manner, the support block 12 is a curved plate 122 .

[0036] In this embodiment, the support block 12 is made by bending a plate, and the cross-sectional radius of the support block 12 is greater than the radius of the tension spring 21. With such a configuration, when the tension spring 21 is installed, the circumference of the tension spring 21 is in contact with the surface of the groove 121, which is conducive to manually pushing the tension spring 21 to move in the groove 121 and install it to the tension cylinder 22. When the tension spring 21 is removed, the surface of the groove 121 is in contact with the circumference of the tension spring 21, which is conducive to the groove 121 supporting the tension spring 21, and the tension spring 21 moves along the groove 121 and separates from the tension cylinder 22.

[0037] In a possible embodiment, the fixed block 11 includes at least a first rib plate 111, a second rib plate 112, a third rib plate 113 and a fourth rib plate 114, the first rib plate 111 and the second rib plate 112 are connected to the first side wall 233 of the beam body 23, the first rib plate 111 and the second rib plate 112 are spaced apart along the length direction of the groove 121, the third rib plate 113 and the fourth rib plate 114 are connected to the second side wall 234 of the beam body 23, the third rib plate 113 and the fourth rib plate 114 are spaced apart along the length direction of the groove 121, and the first rib plate 111, the second rib plate 112, the third rib plate 113 and the fourth rib plate 114 are fixedly connected to the support block 12 respectively.

[0038] In a possible implementation, the support block 12 is an arc-shaped plate 122 , and a surface of the first rib plate 111 close to the support block 12 is an arc surface 115 , and the arc surface 115 corresponds to the support block 12 .

[0039] In this embodiment, the first rib plate 111, the second rib plate 112, the third rib plate 113 and the fourth rib plate 114 are used to stably support and fix the support block 12. When installing or removing the tension spring 21, the support block 12 stably supports the tension spring 21 to reduce the influence of the gravity of the tension spring 21 on the efficiency of disassembly or installation.

[0040] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
