TECHNICAL FIELD

[0001] The utility model relates to a hoist equipment technical field, concretely relates to a kind of resting device for machining of slewing mechanism. BACKGROUND

[0002] In the process of crane operation, slewing mechanism plays a vital role, and slewing mechanism makes the slewing part of the crane rotate in the horizontal plane, thereby realizing the horizontal movement of goods. However, since the slewing mechanism needs to bear a large load during operation, it is necessary to maintain high precision during machining of the slewing mechanism. In addition, due to the large size and heavy weight of the slewing mechanism, it needs to be fixed using a tool before machining to ensure that the slewing mechanism can meet the required precision requirements during machining.

The motor rotates synchronously through the plurality of punching elements and the transmission gears arranged on the surfaces of the punching elements, realizing simultaneous machining of the plurality of mounting holes on the surface of the slewing bearing, saving a lot of machining time. At the same time, the punching elements do not need to move up and down constantly, and the device is provided with one power source to drive multiple punching elements to work, saving the use cost of the device and further saving the machining cost of the slewing bearing.

[0004] The above document, before machining the slewing bearing, places the slewing bearing on the surface of the workbench, and then clamps and fixes the slewing bearing by driving the arc-shaped limiting plate with the electric telescopic rods at both ends. The arc-shaped limiting plate can only limit the horizontal movement of the slewing bearing, but the drill bit rotates on the slewing bearing during the punching process, and the slewing bearing is not only subjected to the pressure of the drill bit in the vertical direction, but also subjected to the rotating force of the drill bit in the horizontal direction. Therefore, the slewing bearing will rotate under force in the horizontal direction, and the arc-shaped limiting plate cannot prevent the slewing support from rotating, which may cause deviation during machining and affect the machining precision.

DETAILED DESCRIPTION

[0028] like Figures 1-4 As shown, a shelf device for rotary mechanism processing is used to place a rotary mechanism 4, which includes a rotary mechanism body 41 and a rotary panel 411 arranged at one end of the rotary mechanism body 41, a support 42 is provided at the other end of the rotary body 41, and assembly holes 4110 arranged at intervals along the circumferential direction are provided on the rotary panel 411, including a base 1, the base 1 is provided with a limiting mechanism 2 and a supporting mechanism 3, the limiting mechanism 2 includes a limiting plate 21, the limiting plate 21 is provided with more than two limiting holes 22, the limiting plate 21 is connected to one side of the base 1, the supporting mechanism 3 includes a support column 31, the support column 31 is connected to the other side of the base 1, and the rotary mechanism 4 includes The rotating mechanism body 41 and the support 42 are connected. Before processing the rotating mechanism 4, the rotating mechanism 4 is placed on the base 1. The base 1 plays a role of fixing and supporting. The limit plate 21 mainly provides support for the rotating mechanism body 41 and limits the moving range of the rotating mechanism body 41 to prevent the rotating mechanism body 41 from deviating from the expected position during processing. The support column 31 mainly provides support for the support 42. Under the joint action of the limit plate 21 and the support column 31, the rotating mechanism 4 is firmly placed on the base 1, and the rotating mechanism 4 is in a horizontal state, which reduces the leveling time of the rotating mechanism 4 during processing.

[0029] The limit plate 21 has an arc-shaped structure, and the limit plate 21 has an arc-shaped structure that can fit tightly with the rotating mechanism 4, so that the limit plate 21 can limit the horizontal movement of the rotating mechanism 4, prevent the rotating mechanism 4 from exceeding the expected position during processing, and provide support for the rotating mechanism 4. The arc-shaped structure of the limit plate 21 can evenly bear force and avoid local stress concentration.

[0030] like Figures 3-4 As shown, the slewing mechanism 4 is provided with an assembly hole 4110 for connecting with the crane equipment, and also provides a connection position for the limit plate 21, so that when the slewing mechanism 4 is placed on the limit plate 21, the limit plate 21 can be first connected to the slewing mechanism 4 through the assembly hole.

[0031] The limiting plate 21 is provided with more than two limiting holes 22, and the limiting holes 22 are provided with fasteners 23. The limiting holes 22 match the assembly holes. The limiting holes 22 are provided on the limiting plate 21. The size of the limiting holes 22 is consistent with the size of the assembly holes. The distribution position of the limiting holes 22 on the limiting plate 21 is the same as the distribution position of the assembly holes on the rotating mechanism body 41. In addition, the limiting holes 22 are provided with fasteners 23. The fasteners 23 can pass through the limiting holes 22 and then pass through the assembly holes, thereby completing the limitation between the rotating mechanism 4 and the limiting plate 21, preventing the rotating mechanism 4 from being displaced during processing.

[0032] like Figure 3 As shown, a first lifting lug 24 is provided on one side of the limiting plate 21 , and the first lifting lug 24 provides a connection position for the lifting equipment.

[0033] The support column 31 is provided with a truncated platform 311, and a second lifting lug 312 is also provided on one side of the support column 31. The truncated platform 311 is provided on the support column 31, and the cross-sectional area of ​​the truncated platform 311 is larger than the cross-sectional area of ​​the support column 31. When the truncated platform 311 abuts the support 42, the contact area between the truncated platform 311 and the support 42 is increased, which can better bear the weight of the slewing mechanism 4 and ensure that the slewing mechanism 4 remains stable during processing. The support column 31 is also provided with a second lifting lug 312 on one side. The second lifting lug 312 provides a connection position for lifting equipment, which can lift and move the base 1 to another location through the first lifting lug 24 and the second lifting lug 312.

[0034] like Figure 5 As shown, the cross section of the support 42 is matched with the cross section of the truncated cone 311, and a mounting hole 420 is provided on the support 42. The support 42 is set on the truncated cone 311 to achieve contact, and the limiting function can also be achieved by inserting a limiting column (not shown in the figure) into the mounting hole 420, thereby increasing the contact area and improving the reliability of the abutment.

[0035] The cross section of the base 1 is a triangular structure. The triangle has stability. The base 1 can more effectively disperse the load from the rotating mechanism 4 and reduce deformation caused by weight or movement, so that it can better carry the rotating mechanism 4 and better maintain the stability of the rotating mechanism 4.

[0036] The working principle of the present invention is as follows: the lifting equipment moves the slewing mechanism 4 to the corresponding position of the base 1 through the first lifting ear 24 and the second lifting ear 312, so that the upper limit plate 21 on the base 1 abuts against the slewing mechanism body 41, and the support 42 abuts against the round table 311, completing the horizontal placement of the slewing mechanism 4, and then the fastener 23 is passed through the limiting hole 22 and then out of the assembly hole, thereby completing the limitation between the slewing mechanism 4 and the limiting plate 21, preventing the slewing mechanism 4 from being displaced during processing.
