[0027] A boom slider assembly 700, a boom assembly, and an operation machine provided in embodiments of this application are described below with reference to FIG. 1 to FIG. 6. It should be understood that the following description is only example implementations of this application, and does not constitute any particular limitation to this application.

[0028] According to a first aspect of this application, an embodiment provides a boom slider assembly 700. As shown in FIG. 1 to FIG. 6, the boom slider assembly 700 includes: a fixing base 100 provided with a fixing head 101 at one end thereof, and a threaded section 102 at the other end thereof, where the threaded section 102 is configured for secure connection to a boom head 200, a clamping protrusion 103 is provided between the fixing head 101 and the threaded section 102, and a clamping groove 104 is formed between the fixing head 101 and the clamping protrusion 103; a slider body 300, where the slider body 300 allows the fixing base 100 to pass therethrough so that the slider body 300 is attached to the boom head 200; a retaining plate 400, the retaining plate 400 allowing the fixing head 101 to pass therethrough so that the retaining plate 400 is clamped in the clamping groove 104; and a locking member 500, where the locking member 500 is mounted on an outer side of the retaining plate 400 to lock and connect the retaining plate 400 to the fixing base 100.

[0029] In the boom slider assembly 700 provided in this application, the threaded section 102 is provided at one end of the fixing base 100. The fixing head 101 is provided at the other end of the fixing base 100. The clamping protrusion 103 is provided between the fixing head 101 and the threaded section 102. The clamping groove 104 configured to clamp the retaining plate 400 is formed between the clamping protrusion 103 and the fixing head 101. The fixing base 100 is threadedly connected to the boom head 200 by the threaded section 102. The mounting hole 303 is provided in the slider body 300. The mounting hole 303 allows the fixing head 101 to pass through until the slider body 300 attaches to the boom head 200. In addition, the clamping protrusion 103 and a part of the threaded section 102 are located in the mounting hole 303. The clamping protrusion 103 can be constrained and clamped in the mounting hole 303. The spacing between the clamping groove 104 and the boom head 200 can be adjusted by adjusting a thread engagement depth between the threaded section 102 and the boom head 200, thereby enabling the retaining plate 400 to allow the fixing head 101 to pass therethrough so that the retaining plate 400 is clamped in the clamping groove 104. The locking member 500 is locked between the fixing head 101 and the retaining plate 400. In this way, the slider body 300 is securely connected to the boom head 200.

[0030] Through such a structural arrangement, the threaded section 102 is provided at one end of the fixing base 100, and the fixing base 100 is threadedly connected to the boom head 200 by the threaded section 102. When the slider body 300 varies in size, manifested by different hole depths of the mounting hole 303, the spacing between the boom head 200 and the clamping groove 104 is adjusted by adjusting a thread connection depth between the threaded section 102 and the boom head 200, to make the clamping groove 104 partially or fully exposed from an outer side of the mounting hole 303, so that the retaining plate 400 can be clamped in the clamping groove 104 without needing to changing fixing bases 100 of different sizes. Therefore, the boom slider assembly 700 has high universality. In addition, when the fixing base 100 is damaged, it is only necessary to unscrew the threaded section 102 of the fixing base 100 and replace the fixing base 100, so that the maintenance and replacement operations of the fixing base 100 are simple, and the costs are low.

[0031] It should be understood that the boom slider assembly 700 may be mounted on an upper side, a lower side, or left and right sides of the boom head 200. For example, as shown in FIG. 1, in the directions in the figure, a plurality of boom slider assemblies 700 are respectively provided on the upper side, the lower side, and the left and right sides of the boom head 200. As shown in FIG. 2 and FIG. 3, the slider bodies 300 of the boom slider assemblies 700 mounted on the upper side and the lower side of the boom head 200 are arc-shaped slider bodies 300 adapted to the boom section. As shown in FIG. 4 and FIG. 5, the slider bodies 300 of the boom slider assemblies 700 mounted on the left and right sides of the boom head 200 are planar slider bodies 300 adapted to the boom section.

[0032] In an embodiment of this application, the fixing base 100 further includes an adjustment shim 600. The adjustment shim 600 is sleeved over the threaded section 102, and is configured to limit a connection depth between the threaded section 102 and the boom head 200.

[0033] As shown in FIG. 2 and FIG. 4, the adjustment shim 600 is mounted between the boom head 200 and the clamping protrusion 103. In other words, the adjustment shim 600 is mounted on the threaded section 102. During mounting, the threaded section 102 of the fixing base 100 is screwed into threads of the boom head 200 until the clamping protrusion 103 of the fixing base 100 and an end surface of the boom head 200 are respectively tightly pressed against two sides of the adjustment shim 600. For example, different quantities of adjustment shims 600 may be mounted to limit the depth of the threaded section 102 being screwed into the boom head 200. Alternatively, adjustment shims 600 of different thicknesses may be mounted to limit the depth of the threaded section 102 being screwed into the boom head 200. The adjustment shim 600 is mounted at the threaded section 102, and the clamping protrusion 103 and the boom head 200 are respectively tightly pressed against the two sides of the adjustment shim 600, so that the connection stability and the limiting and adjustment reliability of the fixing base 100 can be enhanced.

[0034] In an embodiment of this application, the slider body 300 includes a fixing portion 301. The fixing portion 301 attaches to the boom head 200. The mounting hole 303 is opened in the fixing portion 301. The mounting hole 303 is adapted to the clamping protrusion 103. The clamping protrusion 103 extends and is clamped in the mounting hole 303.

[0035] A mounting constraint slot is opened in the retaining plate 400. The fixing base 100 extends and is constrained and clamped in the mounting constraint slot. A disassembly-assisting slot 404 is further opened in the retaining plate 400.

[0036] For example, as shown in FIG. 2 to FIG. 5, the slider body 300 includes the fixing portion 301. The fixing portion 301 is configured to be connected to the boom head 200. The slider body 300 further includes a slider portion 302. The slider portion 302 is adapted to an inner wall of the boom section of a telescopic boom. The slider portion 302 is configured to be mounted between every two adjacent boom sections of the telescopic boom. The mounting hole 303 is opened in the fixing portion 301. The size of the mounting hole 303 is adapted to that of the clamping protrusion 103. The clamping protrusion 103 can extend and be clamped in the mounting hole 303. The mounting hole 303 can constrain the clamping protrusion 103 to some extent. The mounting constraint slot is provided in the retaining plate 400. When the retaining plate 400 is connected to the fixing base 100, the fixing base 100 extends and is constrained in the mounting constraint slot.

[0037] In addition, a disassembly-assisting slot 404 is further provided in the retaining plate 400. For example, the disassembly-assisting slot 404 includes, but is not limited to, an oblong slot or a circular slot. When the retaining plate 400 needs to be mounted and clamped or disassembled, a finger may be inserted into the disassembly-assisting slot 404 to push the retaining plate 400, or a corresponding tool may be inserted into the disassembly-assisting slot 404 to push the retaining plate 400.

[0038] For example, as shown in FIG. 2 and FIG. 3, in an embodiment of this application, the mounting constraint slot includes a mounting slot 401 and a constraint slot 402. The mounting slot 401 is in communication with the constraint slot 402. The diameter of the mounting slot 401 is greater than that of the fixing head 101. The diameter of the constraint slot 402 is greater than an inner diameter of the clamping groove 104. The diameter of the constraint slot 402 is less than that of the fixing head 101.

[0039] During assembly, first, the fixing head 101 is passed through the retaining plate 400 from the mounting slot 401. Then, the retaining plate 400 is pulled along the direction of the constraint slot 402 to clamp the fixing head 101 on an outer side of the constraint slot 402. Finally, the locking member 500 is connected to the fixing head 101 and the retaining plate 400 to prevent the fixing head 101 from shifting into the mounting slot 401 to be detached from the retaining plate 400.

[0040] For another example, as shown in FIG. 4 and FIG. 5, the mounting constraint slot includes a constraint open slot 403. The width of the constraint open slot 403 is greater than an inner diameter of the clamping groove 104, and the width of the constraint open slot 403 is less than a diameter of the fixing head 101.

[0041] During assembly, a rod portion at the inner diameter of the clamping groove 104 is moved from an opening end of the constraint open slot 403 into the constraint open slot 403, and the fixing head 101 is clamped on an outer side of the constraint open slot 403. Then, the fixing base 100 is locked on an inner side of the constraint open slot 403 using the locking member 500.

[0042] In an embodiment of this application, at least one fixing base 100 is provided. The fixing base 100 is disposed in one-to-one correspondence with the mounting hole 303 and the mounting constraint slot. For example, in the embodiment shown in FIG. 2 and FIG. 3, the boom slider assembly 700 includes three fixing bases 100. Three mounting holes 303 are correspondingly opened in the fixing portion 301 of the slider body 300. Three mounting constraint slots are correspondingly opened in the retaining plate 400. For another example, in the embodiment shown in FIG. 4 and FIG. 5, the boom slider assembly 700 includes two fixing bases 100. Two mounting holes 303 are correspondingly opened in the fixing portion 301 of the slider body 300. Two mounting constraint slots are correspondingly opened in the retaining plate 400.

[0043] In an embodiment of this application, the locking member 500 includes a locking plate 501. The locking plate 501 is bridged over one mounting slot 401. One end of the locking plate 501 is connected to the retaining plate 400 by a first locking screw 502. The other end of the locking plate 501 is connected to the retaining plate 400 by a second locking screw 503.

[0044] In an embodiment of this application, the locking plate 501 is provided with an opening slot 504 and a sliding slot 505. The first locking screw 502 is passed through the opening slot 504 from an outer side of the locking plate 501 to be connected to the retaining plate 400, and the second locking screw 503 passes through the sliding slot 505 from the outer side of the locking plate 501 to be connected to the retaining plate 400.

[0045] The locking member 500 further includes a locking pin 506. A locking hole is opened at the opening slot 504. The locking pin 506 is configured to be inserted into the locking hole to prevent the first locking screw 502 from sliding out of the opening slot 504. The disassembly-assisting slot 404 is provided in the locking plate 501.

[0046] For example, as shown in FIG. 2 to FIG. 5, the opening slot 504 is opened at one end of the locking plate 501, and the sliding slot 505 is provided at the other end. The opening slot 504 is a slot structure with an opening formed at one end. The sliding slot 505 is a closed slot structure. The direction of the opening slot 504 is the same as that of the sliding slot 505. The first locking screw 502 is movable along the opening slot 504, and the second locking screw 503 is movable along the sliding slot 505. A first threaded hole and a second threaded hole are respectively opened on two sides of the mounting slot 401 of the retaining plate 400.

[0047] During assembly, the locking plate 501 is first bridged to an outer side of the mounting slot 401, then the second locking screw 503 is passed through the sliding slot 505 to be connected to the second threaded hole, and the first locking screw 502 is passed through the opening slot 504 to be connected to the first threaded hole. Finally, the locking pin 506 is inserted in the locking hole at the opening slot 504 to prevent the first locking screw 502 from being detached from the opening slot 504.

[0048] During disassembly, the locking pin 506 is first disassembled from the opening of the opening slot 504. Then the locking plate 501 is pulled through the disassembly-assisting slot 404 toward a side away from the first locking screw 502 to detach the first locking screw 502 from the locking plate 501. The locking plate 501 is then rotated, so that the locking plate 501 rotates toward a side away from the mounting slot 401. In this case, the retaining plate 400 is pulled again to move the fixing head 101 into the mounting hole 303. Finally, the retaining plate 400 is pulled toward a side away from the fixing head 101 to detach the retaining plate 400 from the fixing head 101.

[0049] As can be learned from the foregoing description, through such a structural arrangement, it can be convenient for a worker to assemble and disassemble the boom slider assembly 700, thereby greatly enhancing the assembly and disassembly efficiency of the boom slider assembly 700.
