DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0028] In the description of the present invention, it should be understood that the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] like Figure 1As shown, a suspension cross arm 100 according to an embodiment of the present invention includes a cross arm base 110 , a pulling seat 120 , a first pulling component 130 and a second pulling component 140 .

[0031] The cross arm base 110 can be used to suspend a picking device, such as a mechanical claw. The cross arm base 110 has a first end 111 and a second end 112 that are arranged opposite to each other. The first end 111 can be used to connect to a lifting column. The pulling seat 120 is arranged on the cross arm base 110 and close to the first end 111. The pulling seat 120 can also be used to connect to a lifting column.

[0032] Further integration Figure 2 As shown, the first pulling member 130 and the second pulling member 140 each include a first pull rod 131, a tension adjusting member 132 and a second pull rod 133 which are connected in sequence. Adjustment threaded holes 1321 are respectively provided at opposite ends of the tension adjusting member 132, and one end of the first pull rod 131 and one end of the second pull rod 133 are respectively threadedly connected to the adjustment threaded holes 1321 at both ends of the tension adjusting member 132. The other end of the first pull rod 131 is connected to the pulling seat 120, and the other end of the second pull rod 133 is connected to the cross arm base 110 and is close to the second end 112. The height of one end of the first pull rod 131 connected to the pulling seat 120 is higher than that of one end of the second pull rod 133 connected to the cross arm base 110. As the equipment runs for a longer time, the second end 112 of the cross arm base 110 tends to deform and fall. The tension adjusting member 132 can be rotated to allow the first pull rod 131 and the second pull rod 133 to penetrate deeper into the adjustment threaded holes 1321 at both ends of the tension adjusting member 132, thereby tightening the first pulling member 130 and the second pulling member 140. This can apply a greater tension to the second end 112 of the cross arm base 110, thereby achieving a horizontal correction for the cross arm base 110.

[0033] The first pull rod 131 of the first pulling member 130 and the first pull rod 131 of the second pulling member 140 are intersected and rotatably connected. In this way, a plurality of triangular stable structures are formed, which not only have structural stability, but also can better correct the horizontality of the cross arm base 110 through the diagonal pulling force, thereby effectively preventing the deformation and falling of the suspension cross arm 100 during long-term operation, resulting in abnormalities such as basket pressing and leakage.

[0034] In one example, the cross arm base 110 includes a mounting base plate 113 and a surrounding plate 114. The mounting base plate 113 is used to mount the pickup device, and the surrounding plate 114 is arranged on the mounting base plate 113 to form an inner cavity 115. The pulling seat 120, the first pulling component 130 and the second pulling component 140 are all arranged in the inner cavity 115.

[0035] In one example, the first pull rod 131 is connected to the pulling seat 120 via a first pull ring.

[0036] In one example, the second pull rod 133 is connected to the cross arm base 110 via a second pull ring.

[0037] like Figure 2 As shown, in one example, the tension adjusting member 132 is provided with an opening 1322 between its two ends. The opening 1322 can be used for inserting a rod or other tools, so that the tension adjusting member 132 can be rotated more conveniently and labor-savingly to adjust the tension of the pulling component.

[0038] In one example, the tension adjustment member 132 is a cantilevered beam pull rod.

[0039] like Figure 2 As shown, in one example, the first pull rod 131 includes a first connecting section 1311, a second connecting section 1312, and a third connecting section 1313 connected in sequence. The first connecting section 1311 and the third connecting section 1313 are respectively threadedly connected to both ends of the second connecting section 1312. The second connecting section 1312 of the first pulling member 130 and the second connecting section 1312 of the second pulling member 140 are intersected and rotatably connected.

[0040] The second connecting section 1312 of the first pulling member 130 and the second connecting section 1312 of the second pulling member 140 are, for example, pin connections, hinge connections, etc. The rotatable connecting member may be damaged under long-term tension, and the detachable second connecting section 1312 can be easily replaced and repaired.

[0041] In one example, the second connecting section 1312 uses a nut with positive and negative thread lengths.

[0042] like Figure 1 As shown, in one example, the suspension cross arm 100 further includes a reinforcing rib 116, which is disposed on the cross arm base 110, and more specifically, the reinforcing rib 116 is disposed on the mounting base 113. In addition, the reinforcing rib 116 is close to the second end 112, and the second tie rod 133 is connected to the reinforcing rib 116. The reinforcing rib 116 is a strip-shaped structure protruding from the upper surface of the cross arm base 110, and the structural stability of the cross arm base 110 can be improved by providing the reinforcing rib 116 and connecting it with the second tie rod 133.

[0043] like Figure 3As shown, in one example, the pulling seat 120 includes a connecting mechanism 121, a height adjustment mechanism 122 and a fastening mechanism 123. The connecting mechanism 121 is connected to the first pull rod 131. The height adjustment mechanism 122 is used to adjust the height of the connecting mechanism 121, which can increase the pulling force on the first pull rod 131, that is, the pulling force on the second end 112 of the cross arm base 110. The connecting mechanism 121 is movably connected to the cross arm base 110. A guide structure, such as a guide rail, a guide groove, etc., can be provided on the side wall of the cross arm base 110, and the guide structure extends in the vertical direction to limit the moving direction of the connecting mechanism 121 to the vertical direction.

[0044] More specifically, the height adjustment mechanism 122 has a support slope 1221, and the support slope 1221 gradually changes in height in the direction from the first end 111 to the second end 112 of the cross arm base 110. The connecting mechanism 121 is movably arranged on the support slope 1221. When the height adjustment mechanism 122 moves, the connecting mechanism (121) rises or falls. The fastening mechanism 123 is detachably connected to the connecting mechanism 121 and the height adjustment mechanism 122 to fix the relative position of the connecting mechanism 121 and the height adjustment mechanism 122. The fastening mechanism 123 is, for example, a bolt. The connecting mechanism 121 and the height adjustment mechanism 122 are provided with corresponding slide grooves 124, which extend in the direction from the first end 111 to the second end 112 of the cross arm base 110. The fastening mechanism 123 penetrates into the slide groove 124 to press the connecting mechanism 121 onto the height adjustment mechanism 122. When adjusting the height of the connecting mechanism 121, first loosen the fastening mechanism 123, adjust the position of the height adjustment mechanism 122, and after the connecting mechanism 121 rises or falls to the required height, insert the fastening mechanism 123 into the slide groove 124 and lock it to fix the relative position of the connecting mechanism 121 and the height adjustment mechanism 122.

[0045] In one example, the support slope 1221 gradually increases in height from the first end 111 to the second end 112 of the cross arm base 110. The longitudinal section of the height adjustment mechanism 122 is, for example, a trapezoid, and the thickness of the height adjustment mechanism 122 gradually increases in thickness from the first end 111 to the second end 112 of the cross arm base 110.

[0046] In one example, the pulling seat 120 further includes a supporting seat 125 , which is disposed on the cross arm base 110 , and the height adjustment mechanism 122 is disposed on the supporting seat 125 and supported by the supporting seat 125 .

[0047] The height adjustment mechanism 122 is connected to the support base 125 via a fixing component. The fixing component includes a fixing beam 1261 and a locking member 1262. The fixing beam 1261 is fixed to the support base 125, and the height adjustment mechanism 122 is connected to the fixing beam 1261 via the locking member 1262.

[0048] In one example, the connection mechanism 121 includes a bottom plate 1211, a first side plate 1212, a second side plate 1213 and a crossbeam 1214. The bottom plate 1211 is movably arranged on the support slope 1221, the first side plate 1212 and the second side plate 1213 are respectively arranged on the bottom plate 1211 and arranged opposite to each other, the first pull rod 131 of the first pulling component 130 is connected to the first side plate 1212, and the first pull rod 131 of the second pulling component 140 is connected to the second side plate 1213. The first side plate 1212 and the second side plate 1213 are connected by the crossbeam 1214. The crossbeam 1214 supports the first side plate 1212 and the second side plate 1213, prevents the first side plate 1212 and the second side plate 1213 from being deformed under the action of tension, and makes the structure more stable.

[0049] Furthermore, the first pull rod 131 of the first pulling component 130 is close to the position where the cross beam 1214 is connected to the first side plate 1212, for example, the position connected to the first side plate 1212 is basically the same, and the first pull rod 131 of the second pulling component 140 is close to the position where the cross beam 1214 is connected to the second side plate 1213, for example, the position connected to the second side plate 1213 is basically the same. In this way, the first pull rod 131 of the first pulling component 130, the first pull rod 131 of the second pulling component 140 and the cross beam 1214 form a triangular stable structure, which improves the structural stability of the device and better prevents structural deformation.

[0050] The suspension cross arm 100 is provided with a pulling seat 120 near the first end 111 on the cross arm base 110, and a first pulling component 130 and a second pulling component 140 are provided to connect the pulling seat 120 and the second end 112 of the cross arm base 110. The pulling component includes a first pull rod 131, a tension adjusting member 132 and a second pull rod 133 which are threadedly connected in sequence. The height of the first pull rod 131 connected to one end of the pulling seat 120 is higher than that of the second pull rod 133 connected to the cross arm base 110. At one end of the cross arm base 110, as the operation time of the equipment increases, the second end 112 of the cross arm base 110 tends to deform and fall. By rotating the tension adjustment member 132, the first pull rod 131 and the second pull rod 133 can be further inserted into the adjustment threaded holes 1321 at both ends of the tension adjustment member 132, thereby tightening the first pulling member 130 and the second pulling member 140, so as to apply a greater tension to the second end 112 of the cross arm base 110, thereby playing a role in horizontal correction of the cross arm base 110. By setting the first pull rod 131 of the first pulling member 130 and the first pull rod 131 of the second pulling member 140 to cross and be rotatably connected, a plurality of triangular stable structures are formed, which not only have structural stability, but also can better correct the cross arm base 110 horizontally through the diagonal pulling force, thereby effectively preventing the deformation and falling of the suspension cross arm 100 during long-term operation, resulting in abnormalities such as basket pressing and leakage.

[0051] Furthermore, the utility model also provides a transporting device.

[0052] like Figure 4 As shown, a handling device 10 of an embodiment includes a suspension cross arm 100, a lifting column 200 and a plurality of picking devices 300 of any of the above examples. The plurality of picking devices 300 are distributed and suspended on a cross arm base 110, and the lifting column 200 is connected to a first end 111 of the cross arm base 110 to drive the suspension cross arm 100 and the plurality of picking devices 300 to rise or fall as a whole.

[0053] In one example, the lifting column 200 includes a lifting seat and a motor screw transmission assembly disposed on the lifting seat, and the motor screw transmission assembly is connected to the first end 111 of the cross arm base 110 to drive the suspension cross arm 100 to rise and fall. Further, the lifting column 200 may also include a guide component extending in the vertical direction, the guide component is disposed on the lifting seat, and the cross arm base 110 is movably connected to the guide component, so that the stability of the suspension cross arm 100 can be improved. The guide component is, for example, a guide rail.

[0054] The picking device 300 may be, for example but not limited to, a mechanical claw, a hook, etc., and may be capable of picking up the loading basket.

[0055] There are multiple picking devices 300, which can pick up multiple loading baskets at the same time. In one example, the number of picking devices 300 is 4 to 12, for example, 4, 6, 8, 10, 12, etc.

[0056] like Figure 4 As shown, in one example, the handling device 10 further includes a counterweight device 400. The counterweight device 400 includes a connecting seat 410 and a counterweight piece 420. The connecting seat 410 and the suspension cross arm 100 are respectively located on opposite sides of the lifting column 200, and the counterweight piece 420 is arranged on the connecting seat 410. By arranging the above-mentioned counterweight device 400, the forces on both sides of the lifting column 200 are more balanced, so that the lifting column 200 remains stable during the movement, and the lifting column 200 is prevented from tilting due to uneven forces for a long time, thereby causing the suspension cross arm 100 to tilt. Among them, the counterweight piece 420 is preferably a high-density, corrosion-resistant metal part.

[0057] In one example, the counterweight 420 is movably disposed on the connecting seat 410 , and the distance between the counterweight 420 and the lifting column 200 can be adjusted, so that the force on both sides of the lifting column 200 can be more flexibly adjusted to be balanced.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
