[0033] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.
[0034] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.
[0035] like Figures 1 to 5 As shown, an exemplary embodiment of the present application provides an engineering machine, which includes a turntable 1 and a walkway 2. The turntable 1 includes a turntable hinge seat 11 arranged on the lateral outer wall of the top of the turntable 1, and the walkway 2 includes a plate body 21, a plate body hinge seat 22 and a guardrail 23. The plate body hinge seat 22 is arranged on the lateral outer wall of the plate body 21 and is hinged to the turntable hinge seat 11 through a hinge structure. The guardrail 23 is arranged on the top surface of the plate body 21, so that the plate body 21 can swing up to drive the guardrail 23 to rotate to the avoidance position above the turntable 1.
[0036] Therefore, during the transfer operation, by swinging the plate body 21 of the walkway 2 upward to a position relatively fitted with the outer wall of the turntable 1, the guardrail 23 arranged on the top surface of the plate body 21 can be transferred to an avoidance position above the turntable 1, so that the overall lateral width of the turntable 1 is reduced to meet its transportation requirements. The key point is that during the folding of the walkway 2, there is no need to dismantle, recycle, etc. the guardrail 23, which is conducive to further improving the operation efficiency.
[0037] It should be noted that, in this embodiment, the construction machinery may be a crawler crane, an excavator, etc., and this application does not limit this.
[0038] Reference Figure 4 When the guardrail 23 is in the avoidance position, the plate 21 is arranged perpendicular to the top surface of the turntable 1, thereby reserving sufficient space for the side of the turntable 1, meeting the transportation requirements and effectively avoiding interference with other components.
[0039] exist Figures 2 to 4 In the illustrated embodiment, when the plate body 21 is swung up to the avoidance position, in order to position the plate body 21 and the guardrail 23, the plate body hinge seat 22 is further provided with a limiting structure for positioning the plate body 21. Specifically, the turntable hinge seat 11 further includes a lower limiting structure 112 disposed below the hinge shaft 111, and the outer end of the plate body hinge seat 22 is formed as an abutment end. When the plate body 21 is swung up to the avoidance position, the abutment end of the plate body hinge seat 22 can abut against the lower limiting structure 112 of the turntable hinge seat 11, so that the lower limiting structure 112 can support and position the plate body 21 and the guardrail 23.
[0040] In an optional or preferred embodiment, the lower limit structure 112 is formed as a lower limit pin, and the abutting end of the plate body hinge seat 22 is formed with a lower clamping groove 222 for clamping with the lower limit pin. Therefore, when the lower limit pin is clamped in the lower clamping groove 222, under the limiting effect of the groove walls on both sides of the lower clamping groove 222, the plate body hinge seat 22 can be stably supported on the lower limit pin, effectively preventing the walkway 2 from falling down due to shaking during transportation.
[0041] In order to avoid interference between the abutting end of the plate body articulated seat 22 and the lower limit structure 112 when the plate body 21 is swung to the avoidance position, the articulated structure of the plate body articulated seat 22 is formed as an articulated groove 221, and the turntable articulated seat 11 includes an articulated shaft 111 passing through the articulated groove 221. By adjusting the relative position of the articulated shaft 111 and the articulated groove 221, the walkway 2 can move relative to the turntable articulated seat 11.
[0042] Reference Figure 4 and Figure 5When the plate 21 is swung to the avoidance position, the abutting end of the plate articulated seat 22 first moves to the top of the lower limit structure 112 to prevent the lower limit structure 112 from interfering with the swing of the plate 21. At this time, by moving the plate 21 downward, the hinge shaft 111 can slide relatively in the hinge slot 221, and the abutting end of the plate articulated seat 22 moves to the lower limit structure 112 to abut against it, thereby completing the positioning of the walkway 2. When the walkway 2 needs to be reset, it is only necessary to lift the plate 21 to make the abutting end of the plate articulated seat 22 leave the lower limit structure 112, and then swing the plate 21 downward to unfold the walkway 2 to the working position again.
[0043] In an optional or preferred embodiment, referring to Figure 2 and Figure 3 The turntable articulated seat 11 also includes an upper limit structure 113 disposed obliquely above the lower limit structure 112. The plate body 21 can swing downward from the above-mentioned avoidance position until the outer end of the plate body articulated seat 22 abuts against the upper limit structure 113 upward, so that the plate body 21 can be maintained at an operating position flush with the top surface of the turntable 1 under its own gravity. By adjusting the plate body 21 to a position flush with the top surface of the turntable 1, part of the top surface of the turntable 1 can be used as a part of the walking platform, thereby appropriately reducing the width of the plate body 21 and saving manufacturing costs.
[0044] Specifically, the upper limit structure 113 is formed as an upper limit pin, and the abutting end of the plate body hinge seat 22 is formed with an upper clamping groove 223 for clamping with the upper limit pin. The clamping groove 223 can be a notch formed at the corner of the plate body hinge seat 22, thereby improving the stability of the plate body 21.
[0045] In an optional or preferred embodiment, referring to Figure 5 The turntable hinge seat 11 includes a transverse plate section 114 arranged below the top plate of the turntable 1 and an inclined plate section 115 connecting the transverse plate section 114 , the upper limit structure 113 is arranged on the transverse plate section 114 , and the lower limit structure 112 is arranged on the inclined plate section 115 .
[0046] In an optional or preferred embodiment, referring to Figure 2 and Figure 3 The edge of the top plate of the turntable 1 forms an eaves structure, and the upper limit structure 113 of the turntable hinge seat 11 is arranged below the eaves structure. The edge of the plate hinge seat 22 is concave to form an avoidance gap 224 for avoiding the eaves structure of the turntable 1, so that when the plate body 21 swings down, the abutting end of the plate hinge seat 22 can bypass the eaves structure and abut against the upper limit structure 113 of the turntable hinge seat 11.
[0047] In an optional or preferred embodiment, referring to Figure 2The hinged slide groove 221 is formed as a through slide groove, the part of the hinged shaft 111 passing through the through slide groove forms a limit axis hole, and the walkway 2 also includes a limit pin 24 passing through the limit axis hole.
