Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

Fig. 9 shows a schematic perspective view of a gantry crane 130 according to an embodiment of the first aspect of the present application. As shown in fig. 9, the gantry crane 130 includes a gantry 133, at least one lifting assembly 131, and at least one rotating assembly 132.

Specifically, the lifting assembly 131 includes a first driving device 1311 and a support member 1312, which are connected to each other, the first driving device 1311 is disposed on the gantry 133, the support member 1312 is used for supporting the workpiece 200, and the first driving device 1311 drives the workpiece 200 to lift and lower through the support member 1312.

Illustratively, the first driving device 1311 may be a cylinder, the first driving device 1311 may include a cylinder housing, a piston disposed in the cylinder housing, and a piston rod fixedly connected to the piston and extending out of the cylinder housing, and the support 1312 may be connected to the piston rod. When work piece 200 is in the lift mode, the piston rod can stretch out and draw back for cylinder body to drive support piece 1312 and go up and down, and then make work piece 200 realize going up and down under support piece 1312's drive.

The rotating assembly 132 includes a second driving device 1321 and a clamping member, the second driving device 1321 is disposed on the gantry 133, the clamping member is used for clamping the workpiece 200, and the second driving device 1321 is used for driving the workpiece 200 to rotate through the clamping member.

Exemplarily, the second driving device 1321 may be a motor. When the workpiece 200 needs to be rotated, the workpiece 200 may be lifted by the lifting assembly 131, and the workpiece 200 may be separated from the clamping member during the lifting of the workpiece 200. The clamp is then caused to clamp the workpiece 200. Then, the second driving device 1321 is controlled to operate, the motor shaft can drive the clamping member to rotate, and since the clamping member is fixed relative to the workpiece 200 at this time, the workpiece 200 can rotate together with the clamping member, and the workpiece 200 can be separated from the supporting member 1312 during the rotation of the workpiece 200.

Therefore, by arranging the lifting component 131 and the rotating component 132, the lifting and the rotating of the workpiece 200 can be realized, so that the workpiece 200 can be processed in all directions (for example, welded), the processing requirement of the workpiece 200 is met, meanwhile, the workpiece 200 does not need to be rotated manually, the labor intensity of operators can be reduced, and the production efficiency of the workpiece 200 is improved.

In one embodiment, referring to fig. 9 and 10, the clamp includes at least one actuator 1322 and at least two clamp portions 1323. Wherein the driver 1322 is provided to the gantry 133, the driver 1322 is configured to drive at least one of the at least two clamping portions 1323 to move between a clamping position for clamping the workpiece 200 and a release position for releasing the workpiece 200.

For example, in the example of fig. 10, two actuators 1322 and four clamping portions 1323 are shown, the four clamping portions 1323 constituting two clamping groups, each clamping group comprising two clamping portions 1323. At least one of the clamping portions 1323 of each clamping group is a moving clamping portion 1323, and the moving clamping portion 1323 is connected with a corresponding driver 1322. In the case where the workpiece 200 needs to be rotated, the workpiece 200 may be lifted up by the lifting assembly 131 to a position adjacent to the clamping portions 1323, and then the corresponding movement clamping portions 1323 are controlled to move by the driver 1322, and the two clamping portions 1323 of each clamping group clamp the workpiece 200. Then, the second driving device 1321 is controlled to work, so that the second driving device 1321 drives the driver 1322, the clamping member and the workpiece 200 to rotate together.

Therefore, by arranging the driver 1322 and the clamping portion 1323, the driver 1322 can provide driving force for the corresponding clamping portion 1323, so that the clamping portion 1323 can automatically move, and the moving direction of the clamping portion 1323 can be changed by changing the rotating direction of the driver 1322, so that the clamping portion 1323 can be effectively controlled to clamp the workpiece 200 or loosen the workpiece 200, the operation is more convenient, and the reliability is higher.

In an alternative embodiment, referring to fig. 10, the two clamping portions 1323 may be opposed to each other in the up-down direction, and the two clamping portions 1323 clamp the upper surface and the lower surface of the workpiece 200 with the clamping portions 1323 in the clamping position, respectively.

Here, the "upper surface of the workpiece 200" may be understood as the upper surface of the workpiece 200 before the workpiece 200 is rotated, and similarly, the "lower surface of the workpiece 200" may be understood as the lower surface of the workpiece 200 before the workpiece 200 is rotated. It is understood that the "upper surface of the workpiece 200" and the "lower surface of the workpiece 200" may be rotated to other directions during the rotation of the workpiece 200.

Therefore, by the arrangement, the two side surfaces of the workpiece 200 in the thickness direction can be clamped, so that the workpiece 200 can be clamped more firmly while the operation is facilitated, and the clamping part 1323 and the workpiece 200 are prevented from moving relatively, so that the rotation of the workpiece 200 is safer and more reliable.

In one embodiment, as shown in fig. 10 and 11, the second driving device 1321 is a motor including a motor body and a motor shaft, and the motor body is fixed to the gantry 133. The rotating assembly 132 further includes a fixing plate 1324, the fixing plate 1324 is fixedly connected to a motor shaft, the clamping member is disposed on one side of the fixing plate 1324 away from the motor body, and the motor shaft drives the workpiece 200 to rotate through the fixing plate 1324.

Illustratively, the motor shaft may extend from one side of the motor body. The fixing plate 1324 is located between the motor body and the holder. In the case where the workpiece 200 needs to be rotated, the clamp portion 1323 is in the clamping position. The motor shaft rotates the fixing plate 1324, and the clamping member is fixed to the fixing plate 1324, so that the clamping member can rotate together with the fixing plate 1324. And because the workpiece 200 and the clamping member are relatively fixed, the workpiece 200 can be driven by the clamping member to rotate together.

From this, through setting up foretell fixed plate 1324, can provide the mounted position for the holder, realize firm fixed of holder, moreover, the motor shaft can drive holder and work piece 200 rotation through fixed plate 1324 to make the motor shaft can need not directly to link to each other with the holder, thereby can be when guaranteeing the normal rotation of work piece 200, can reduce the installation degree of difficulty, make whole longmen lift 130's structure simpler.

In one embodiment, referring to fig. 9 and 11, the gantry 133 includes a first connecting rod 1331 and two second connecting rods 1332, two ends of the first connecting rod 1331 are respectively connected to top ends of the two second connecting rods 1332, and the supporting member 1312 is a supporting rod which is parallel to the first connecting rod 1331.

For example, in the example of fig. 9 and 11, the first connection rod 1331 extends horizontally and both second connection rods 1332 extend vertically. The second driving means 1321 is provided on the first connection rod 1331, and the second driving means 1321 is provided on the first connection rod 1331. The lifting assembly 131 may further include a mounting bar, and the mounting bar and the support bar may be formed in an "L" shaped structure. Wherein the mounting bars are connected between the support bars and the corresponding second connection bars 1332, and the mounting bars are perpendicular to the first connection bars 1331.

Thus, by making the supporting members 1312 be supporting rods, the supporting members 1312 are relatively small in size, so that while the workpiece 200 is effectively supported, the occupied space can be reduced, and the arrangement is more convenient. By the support rod being parallel to the first connection rod 1331, it is ensured that the workpiece 200 can be maintained in a horizontal state under the supporting action of the support rod when the workpiece 200 is in a lifting mode, so that the lifting stability of the workpiece 200 can be improved, and the workpiece 200 is prevented from being inclined in the lifting process.

Further, referring to fig. 9 and 11, the first connection bar 1331 and the two second connection bars 1332 together define a through-port through which the support 1312 protrudes. For example, in the example of fig. 9 and 11, one end of a support 1312 is connected to the mounting bar and the other end of the support 1312 extends toward the other support 1312 such that an orthographic projection of the other end of the support 1312 on the access opening covers a portion of the access opening.

Therefore, the length of the supporting member 1312 is relatively long, so that the contact area between the supporting member 1312 and the workpiece 200 can be increased, the supporting reliability of the supporting member 1312 can be improved, potential safety hazards caused by the fact that the workpiece 200 is separated from the supporting member 1312 in the lifting process of the workpiece 200 can be avoided, the pressure intensity can be reduced, the supporting member 1312 or the workpiece 200 is prevented from being deformed and damaged, and the structural reliability of the supporting member 1312 and the workpiece 200 can be improved.

The lifting system according to the embodiment of the second aspect of the present application comprises at least one gantry lift 130 according to the embodiment of the first aspect of the present application described above.

According to the lifting system of the embodiment of the application, the lifting and the rotation of the workpiece 200 can be realized by adopting the gantry crane 130, so that the workpiece 200 can be processed in all directions, the processing requirement of the workpiece 200 is met, meanwhile, the workpiece 200 does not need to be rotated manually, the labor intensity of operators can be reduced, and the production efficiency of the workpiece 200 is improved.

In one embodiment, referring to fig. 1, the gantry 133, the lifting assembly 131 and the rotating assembly 132 of the gantry crane 130 are two, the two gantries 133 are spaced apart, the workpiece 200 is suitable to be disposed between the two gantries 133, two ends of the workpiece 200 are respectively supported on the supporting members 1312 of the two lifting assemblies 131 during the lifting of the workpiece 200, and two ends of the workpiece 200 are respectively clamped by the clamping members of the two rotating assemblies 132 during the rotating of the workpiece 200.

With such an arrangement, in the lifting process of the workpiece 200, the two supporting members 1312 can respectively support two ends of the workpiece 200, so that the stress of the workpiece 200 is more balanced, and the lifting of the workpiece 200 is more stable and is not easy to shake; in the rotation process of the workpiece 200, the two clamping pieces can respectively clamp two ends of the workpiece 200, so that the stress of the workpiece 200 is more balanced, and the workpiece is not easy to shake in the rotation process.

In one embodiment, at least one of the second drives 1321 of the two rotary assemblies 132 is operated during rotation of the workpiece 200.

In one example, one of the two second driving devices 1321 operates during the rotation of the workpiece 200. One of the two second driving devices 1321 is a driving device, and the other of the two second driving devices 1321 is a driven device. The driving device can drive the workpiece 200 to rotate through the corresponding clamping pieces, and the workpiece 200 can drive the other clamping piece and the driven driving device to rotate because the two clamping pieces clamp the workpiece 200. In this way, the power consumption can be reduced, the service life of the second driving device 1321 can be extended, and the cost can be reduced.

Of course, the present application is not limited thereto, and in another example, both of the second driving devices 1321 are operated during the rotation of the workpiece 200. By such arrangement, the stress on the workpiece 200 can be more uniform, the driving force required to be provided by each driving device is reduced, and the rotation of the workpiece 200 is more reliable.

Specifically, the first transfer rail assembly 110 includes at least one first transfer member 111 that is movable. The clamp 120 comprises a base 121 and at least one clamping assembly 122 arranged on the base 121, the first conveying member 111 is used for carrying the base 121 to convey the clamp 120, and the clamping assembly 122 is used for clamping the workpiece 200, such as fixedly clamping an unwelded dirt box accessory. The support 1312 supports the workpiece 200 through the clamp 120, and the first driving device 1311 drives the clamp 120 and the workpiece 200 to be lifted and lowered together through the support 1312. The clamping member is used for clamping the clamp 120, and the second driving device 1321 is used for driving the clamp 120 and the workpiece 200 to rotate together through the clamping member.

For example, in conjunction with fig. 1 and 13, the first conveying member 111 may move the clamp 120 and the workpiece 200, such as the dirt box, between the processes, for example, the first conveying member 111 may move the clamp 120 and the workpiece 200 in two directions (e.g., forward and backward). In a sewage tank welding process assembly line, the left end position of a first conveying rail assembly 110 is defined as a first process of a sewage tank welding process, a clamp 120 is initially placed on the first conveying rail assembly 110, a workpiece 200 is clamped in the first process, after clamping of all workpieces 200 is completed, a first conveying piece 111 is controlled to drive the clamp 120 and the workpiece 200 to move, a second process is carried out until integral welding of the workpieces 200 such as the sewage tank is completed, transmission operation between any equipment auxiliary processes outside a production line is not needed, and flowing of the sewage tank welding process can be achieved by means of movement of the first conveying piece 111.

That is, the orthographic projection of the first accommodation space on the base 121 covers the orthographic projection of the workpiece 200 on the base 121, and the plurality of clamp assemblies 122 are located on the outer periphery of the workpiece 200 in a state where the workpiece 200 is clamped by the plurality of clamp assemblies 122.

For example, in the example of fig. 5-8, four clamping assemblies 122 are shown, the base 121 is generally rectangular in configuration, and the four clamping assemblies 122 are disposed adjacent to four corners of the base 121, respectively. Each of the clamping assemblies 122 is movable between a clamping position for clamping the workpiece 200 and a release position for releasing the workpiece 200, with the clamping assembly 122 in the clamping position, the workpiece 200 being clamped by four of the clamping assemblies 122, and with the four clamping assemblies 122 each located at a respective corner of the workpiece 200. When welding the workpiece 200, the welding robot 160 may be located at the middle of the workpiece 200, having a large working space.

With such an arrangement, during the ascending process of the fixture 120 and the workpiece 200, the first driving device 1311 can lift the fixture 120 and the workpiece 200 more easily through the supporting member 1312, and the lifting portion 1211 located at the corner can avoid occupying the space in the middle of the base 121, thereby playing an effective avoiding role and avoiding interference with the workpiece 200 and other structural members.

In one example, the number of the elevating portions 1211 is four, and the four elevating portions 1211 are respectively provided at four corners of the base 121. The base 121 includes a frame 1215 and two support bars 1214. The border 1215 can include first and second sides opposite one another, and third and fourth sides opposite one another. Wherein the first and second sides are the long sides of the frame 1215, and the third and fourth sides are the short sides of the frame 1215. The two support rods 1214 are respectively a first rod and a second rod, and the length of the first rod is greater than that of the second rod. The first pole is established on first edge, the one end on first pole and the outside surface parallel and level on first edge to reduce occupation space, the other end on first pole inwards extends, and the second pole is established on the second edge, the one end on second pole and the outside surface parallel and level on second edge, in order to reduce occupation space, the other end of second pole inwards extends, and the above-mentioned other end of second pole and first pole is relative each other.

Here, it should be noted that the direction "inside" can be understood as a direction toward the center of the base 121, and the opposite direction is defined as "outside", i.e., a direction away from the center of the base 121.
