Description

Technical Field

[0001] The utility model relates to the technical field of mill hangers, in particular to a mining mill arc grating hanger structure. Background Art

[0002] With the continuous development of industrialization and the increasing scarcity of energy, mining mills are becoming increasingly larger in size to effectively improve energy utilization. Curved gratings are a frequently used component in large-scale semi-autogenous grinding mills. These gratings are often large and heavy, often requiring the assistance of a robot for gripping and installation to improve installation efficiency.

[0003] In order to facilitate the grasping of the robot, a pair of lifting ears are generally designed on a single curved lifting bar of the curved grating plate. However, during use, the following problems still exist:

[0004] 1. Due to the unique curved lifting bar design of the curved grating plate, there will be various difficulties in designing the lifting lugs. It is difficult to design the lifting lugs symmetrically on the arc line. There is also an error in the distance between the two lifting lugs after layout, which makes it difficult to adapt to the size of the robot.

[0005] 2. Currently, the most common curved lifting bars have only one pair of lifting ears, so they can only be clamped by a robot with two clamping claws, and the curved grating plate cannot be effectively fixed during the installation process; if you want to use a robot with four clamping claws to clamp it, the curved lifting bar does not have a suitable width and position to arrange the lifting ears. Utility Model Content

[0006] The purpose of this utility model is to propose an arc-shaped grating plate lifting fixture structure for a mining mill. On the basis of a pair of lifting ears of an existing arc-shaped lifting bar, an arc-shaped grating plate clamp is designed to cooperate with a manipulator, which has low layout difficulty, and the grabbing process is more stable, which can also promote the improvement of installation efficiency.

[0007] The technical solution adopted by the utility model is: a mining mill arc grating plate lifting device structure, comprising an arc grating plate with an arc grating plate lifting bar, two lifting ears integrally formed on the same arc grating plate lifting bar, and two arc grating plate clamps respectively fixedly connected to the corresponding lifting ears by fasteners;

[0008] Each arc-shaped grating plate fixture has a card slot at the lower end, and the card slot is adapted to the shape of the arc-shaped grating plate lifting strip at its position. The arc-shaped grating plate fixture also has two manipulator card holes;

[0009] The two curved grating plate clamps are fixed in contact with the corresponding lifting ears, and when the card slots are clamped on the curved grating plate lifting bars, the four manipulator clamping holes on the two curved grating plate clamps correspond to the positions of the manipulator claws used to grab the curved grating plates.

[0010] As a preferred solution, the center distance between the two manipulator clamping holes of each arc-shaped grating plate clamp is greater than the width of the clamping slot thereon.

[0011] As a preferred solution, the arc-shaped grating plate clamp has bolt holes for fasteners to pass through, and the bolt holes are located on the center line of the entire arc-shaped grating plate clamp.

[0012] As a preferred solution, the manipulator clamping hole is located above the bolt hole and is symmetrical with respect to the bolt hole.

[0013] As a preferred solution, the two arc-shaped grating plate clamps are respectively attached to the opposite back surfaces of the two lifting ears.

[0014] As a preferred solution, the lifting ear is provided with a hole for the fastener to pass through.

[0015] As a preferred solution, the fastener is a bolt and nut assembly.

[0016] The beneficial effects of the utility model are:

[0017] Based on the defects of the existing technology, a mining mill arc grating hanger structure is provided. Compared with the existing connection method:

[0018] 1. Based on the pair of lifting ears of the existing arc-shaped lifting bar, a curved grating plate fixture is designed to cooperate with the robot arm. The layout is easy, the grasping process is more stable, and the installation efficiency can be improved.

[0019] 2. The lifting holes of the lifting ears are replaced by the manipulator clamping holes of the curved grating plate fixture. The newly added curved grating plate fixture can be redesigned to modify the spacing and angles of the original lifting ears to better fit the size of the manipulator;

[0020] At the same time, since it can be modified, the lifting lugs do not require too high precision when being laid out, which reduces the difficulty of laying out the lifting lugs.

[0021] 3. Each curved grating plate fixture has sufficient width and can be designed with two manipulator clamping holes to match the 4-claw manipulator. Compared with the 2-claw connection method, it is more stable when clamping the curved grating plate;

[0022] 4. The curved grating plate clamp is connected to the lifting lug through fasteners, which facilitates the disassembly and replacement of the curved grating plate clamp.

[0023] 5. The curved grating plate lifting fixture is connected to the lifting lugs through slots and fasteners. When there is only one lifting lug, it can still play an effective fixing role and maintain stability during the lifting process. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may also be beneficially combined in other embodiments.

[0031] It should be noted that: unless otherwise defined, the technical or scientific terms used herein shall have the usual meanings understood by persons of ordinary skill in the field to which the present invention belongs. The words "one", "an" or "the" and the like used in the specification and claims of the present utility model patent application do not express quantity restrictions, but rather indicate the presence of at least one; the words "first", "second" and "third" used herein shall not be regarded as restrictions on the order of components, but merely serve to distinguish different components; words such as "include" or "comprise" indicate that the elements or objects appearing before "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, but do not exclude other elements or objects with the same function.

[0032] In order to more clearly describe the specific structural composition of the arc-shaped grating hanger structure of a mining mill, Figure 1-4 Describe this embodiment:

[0033] like Figure 1 or Figure 2 As shown, a curved grating plate lifting fixture structure for a mining mill includes a curved grating plate with a curved grating plate lifting bar 2, two lifting ears 5 are integrally formed on the same curved grating plate lifting bar 2, and the structure includes two curved grating plate clamps 1 fixedly connected to the corresponding lifting ears 5 by fasteners 3 respectively; the connection method of the fasteners 3 facilitates the disassembly and replacement of the curved grating plate clamps 1.

[0034] In this embodiment, the lifting hole of the lifting ear 5 is replaced by the manipulator clamping hole 102 of the arc-shaped grating plate clamp 1. The newly added arc-shaped grating plate clamp 1 can be redesigned to correct the spacing and angle of the original lifting ear 5 to better adapt to the size of the manipulator 4; at the same time, since it can be modified, the lifting ear 5 does not require too high precision when it is laid out, reducing the difficulty of laying out the lifting ear.

[0035] See Figure 3 Each arc-shaped grating plate clamp 1 has a card slot 101 at the lower end, and the card slot 101 is adapted to the shape of the arc-shaped grating plate lifting bar 2 at its position. The arc-shaped grating plate clamp 1 also has two manipulator card holes 102; the arc-shaped grating plate hanger 1 is connected to the lifting ear 5 through the card slot 101 and the fastener 3. When there is only one lifting ear 5 (one fastener 3), it can still play an effective fixing role and maintain stability during the lifting process.

[0036] When the two curved grating fixtures 1 are secured against their corresponding lifting lugs 5 and the slots 101 are engaged with the curved grating lifting bars 2, the four gripper holes 102 on the two curved grating fixtures 1 correspond to the positions of the gripping claws on the gripper 4 used to grasp the curved grating. Each curved grating fixture 1 is wide enough to accommodate two gripper holes 102, matching the gripper 4 with four jaws. This provides more stable gripping of the curved grating compared to a two-jaw connection.

[0037] During specific use, the two arc-shaped grating plate clamps 1 are respectively attached to the opposite back surfaces of the two hanging ears 5 .

[0038] Figure 3 The manipulator 4 shown in the figure has four claws, which correspond to the two manipulator holes 102 of the two arc-shaped grating plate fixtures 1 respectively. The four manipulator holes 102 on the two arc-shaped grating plate fixtures 1 correspond to each other in pairs. The four claws of the designed manipulator 4 can move relative to or opposite to each other in groups of two. When moving relative to each other, the claws are inserted into the manipulator holes 102 to complete the connection. When moving opposite to each other, the claws are separated from the manipulator holes 102.

[0039] In the above embodiment, the center distance between the two manipulator clamping holes 102 of each arc-shaped grating plate fixture 1 is greater than the width of its upper clamping slot 101. The spacing of the manipulator clamping holes 102 can be designed according to the size of the 4-claw manipulator to adapt to various manipulator sizes.

[0040] Specifically, there is a bolt hole 103 on the curved grating plate clamp 1 for the fastener 3 to pass through, and the bolt hole 103 is on the center line of the entire curved grating plate clamp 1. The manipulator clamp hole 102 is above the bolt hole 103 and is symmetrical about the bolt hole 103. The symmetrical design can ensure uniform force during the lifting process.

[0041] The fastener 3 in the above embodiment is specifically a bolt and nut assembly.

[0042] Parts not described in detail in this embodiment are prior art.

[0043] It should be noted that although the present invention has been described through the above embodiments, the present invention may also have other various embodiments. Without departing from the spirit and scope of the present invention, it is obvious that those skilled in the art may make various corresponding changes and modifications to the present invention, and such changes and modifications shall fall within the scope of protection of the appended claims and their equivalents.
