[0037] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0038] For the existing positioner lifting platform, the accessibility is poor when manually welding workpieces, and only the workpiece can be reached by standing on the lifting platform guardrail for welding, which has the risk of falling from a high altitude and has safety hazards.

[0039] Therefore, the inventor of the present application designs a positioner lifting platform which can be used for welding various structural parts with a welding positioner. The positioner lifting platform comprises a track 11 and a lifting platform, the track 11 is arranged on one side of the positioner 2 along a first direction, and the track 11 extends along the first direction. The lifting platform is arranged on the track 11 and can move along the track 11, and the distance between the lifting platform and the positioner can be adjusted along the track to assist the operator to perform welding construction. The lifting platform comprises a main platform 12 and a sub-platform 13, and the sub-platform 13 is arranged on the main platform 12. The sub-platform 13 can be extended out of the main platform 12 along the first direction and retracted into the main platform 12. As shown in Figure 1 and Figure 6 As shown in Figure 2 、 Figure 4 and Figure 5 In some operation scenarios, the sub-platform 13 is retracted into the main platform 12 and does not interfere with the workpiece. As shown in

[0040] It can be seen that the lifting platform of the present application adopts the embedded sub-platform, which is extended during use and retracted after use, thereby increasing the flexibility of the operation and use of the lifting platform and the accessibility of the manually welded workpieces. The width and the extended length of the sub-platform 13 can cover the maximum welding requirement of the workpieces. During the welding of the workpieces, the sub-platform 13 can be completely retracted into the main platform 12 or extended by a certain length according to the requirement.

[0041] It should be noted that the structure of the positioner 2 and the lifting structure of the lifting platform can be various, and can be designed according to the actual operation requirement. Moreover, the structure principle of the positioner 2 and the lifting structure principle of the lifting platform are well known to those skilled in the art, and do not belong to the core improvement part of the present application, and thus will not be described here. In addition, the telescopic structure between the sub-platform 13 and the main platform 12 can be various, for example, the sub-platform 13 can be provided on the guide rail sliding structure of the main platform 12 for endless position adjustment, or the sub-platform 13 can be detachably clamped on the clamping structure of the main platform 12 arranged along the first direction for multi-segment distance adjustment, etc., which should all belong to the protection scope of the present application.

[0042] Optionally, as shown in Figure 5 and Figure 6 , the main platform 12 can be internally provided with a guide rail 123 extending along the first direction, and the sub-platform 13 is arranged on the guide rail 123 and can be extended or retracted along the guide rail 123. The guide rail 123 can be welded in the main platform 12, which serves as a guide for the sub-platform 13 to ensure the stable extension and retraction of the sub-platform 13. The length of the guide rail 123 is determined according to the length of the sub-platform 13.

[0043] Optionally, in order to facilitate the operation of the operator and improve the processing efficiency, the lifting platform can further include a first driving mechanism arranged on the main platform 12, which is drivingly connected with the sub-platform 13 and used to drive the sub-platform 13 to extend or retract. The first driving mechanism can include a hydraulic cylinder or a gas cylinder device.

[0044] Optionally, the positioner lifting platform further comprises a distance detection device arranged at the protruding front end of the auxiliary platform 13 and configured to detect the distance between the auxiliary platform 13 and the front object, and a controller in communication with the distance detection device and the first driving mechanism, respectively, and configured to control the first driving mechanism to stop and alarm when the detection value of the distance detection device is less than a preset distance value. Specifically, when the auxiliary platform 13 needs to be extended for work, the operator can control the extension of the auxiliary platform 13. The distance detection device can be configured to automatically start and detect the distance between the front end of the auxiliary platform 13 and the front object in real time when the extension of the first driving mechanism is identified. The controller can obtain the real-time distance value detected by the distance detection device in real time. When the controller determines that the real-time distance value is greater than the preset distance value, it can be determined that the auxiliary platform 13 and the front object such as the workpiece 3 are likely to collide. At this time, the controller can immediately control the first driving mechanism to stop, thereby avoiding the collision between the auxiliary platform 13 and the front object such as the workpiece 3, further ensuring the safety of the work, and avoiding the damage to the workpiece 3 and the resulting property loss. The distance detection device can be an infrared distance sensor, a laser sensor, an ultrasonic sensor, etc.

[0045] Optionally, as shown in Figure 5 and Figure 6 , the auxiliary platform 13 can be arranged at the middle part of the main platform 12 in the second direction. In this way, in the second direction, the auxiliary platform 13 can perform welding processing on both ends of the workpiece 3, respectively, and the structure is more reasonable. The second direction is perpendicular to the first direction.

[0046] Optionally, as shown in Figure 3 , the protruding front end of the auxiliary platform 13 can be provided with a first safety guard 131, and the front end of the main platform 12 is provided with a second safety guard 121 and a third safety guard 122 arranged in the second direction. The first safety guard 131 can be welded or bolted to the auxiliary platform 13, and the width of the first safety guard 131 is determined according to the width of the auxiliary platform 13.

[0047] In the retracted position of the auxiliary platform 13, the first safety guard 131 is located between the second safety guard 121 and the third safety guard 122, and the auxiliary platform 13 is flush with the second safety guard 121 and the third safety guard 122, respectively. In this way, a complete and closed safety guard of the lifting platform can be formed, ensuring the safety of the work. The first safety guard 131 and the second safety guard 121 and the third safety guard 122 form a detachable safety connection structure, further ensuring the reliability of the safety guard.

[0048] Optionally, as shown in Figure 4As shown, the positioner lifting platform further comprises a plurality of protective chains 14, which are detachably connected between the first safety guard 131 and the second safety guard 121 and between the first safety guard 131 and the third safety guard 122 in the extended position of the sub-platform 13. In this way, in the extended position of the sub-platform 13, the second safety guard 121, the plurality of protective chains 14, the first safety guard 131, the plurality of protective chains 14 and the third safety guard 122 are sequentially connected to form a closed guard structure, which can ensure the safety of the operation.

[0049] Optionally, as shown in Figure 4 The protective chain 14 is in the form of a chain ring, and the first safety guard 131, the second safety guard 121 and the third safety guard 122 are respectively provided with hooks 17, and the chain ring of the protective chain 14 is detachably hung on the hooks 17, which is convenient to install and disassemble. The number and spacing of the protective chains 14 are configured according to the height of the first safety guard 131 and the protection standard.

[0050] Alternatively, one end of the protective chain 14 can be fixed to the second safety guard 121 or the third safety guard 122, and the other end is a movable end hung on the hook 17 of the first safety guard 131, and the length of the protective chain 14 is determined according to the maximum length of the extension of the sub-platform 13. When the sub-platform 13 is extended, the movable end of the protective chain 14 is hung on the hook 17 of the first safety guard 131 according to the extension length, so that the protective chain 14 is basically taut, ensuring the safety of the operator.

[0051] The existing lifting platform uses a single motor to drive a transmission shaft when moving, and drives the walking wheels at both ends to walk on the track. The single-side driving walking wheels are unevenly stressed, unstable in walking, and the lifting platform has the risk of derailing.

[0052] Therefore, the lifting platform of the present application further comprises a walking chassis 15, which is provided with a transmission shaft 151 and two driving walking wheels 152 and two second driving mechanisms 153 arranged at intervals along the second direction. The two driving walking wheels 152 are fixedly arranged at both ends of the transmission shaft 151 and can walk along the track 11, and the two second driving mechanisms 153 are arranged at both ends of the transmission shaft 151 and are in driving connection with the transmission shaft 151 to drive the transmission shaft 151 to rotate. The second driving mechanism 153 can be a driving motor or other driving structure.

[0053] Specifically, as shown in Figure 5 and Figure 6 The walking chassis 15 is equipped with two driving motors, which drive the driving walking wheels 152 through the transmission shaft 151 to realize the walking of the positioner lifting platform on the track 11. The two motors drive the platform to move, which can make the two driving walking wheels 152 be evenly stressed, avoid the risk of derailing, and increase the stability and safety of the platform when moving.

[0054] The second aspect of the present application also provides a positioner machining system, which can include the positioner 2 and the positioner lifting platform described above. Since the positioner machining system includes the positioner lifting platform described above, it also has all the technical effects brought by the positioner lifting platform, and thus will not be repeated here.

[0055] The operation process of the positioner machining system of the present application will be briefly described below.

[0056] 1. When the positioner lifting platform 1 is matched with the welding positioner for welding, the two second driving mechanisms drive the positioner lifting platform 1 to approach the positioner 2 and the workpiece 3, and the scissor arm 16 lifts the lifting platform to the required height.

[0057] 2) The operator determines whether the workpiece welding area can be reached on the lifting platform. If it can be reached, the lifting platform does not need to be adjusted. If it cannot be reached, the sub-platform 13 is adjusted to extend from the main platform 12, and the extension length is adjusted according to the requirements.

[0058] 3) After the sub-platform 13 extends, the movable end of the protective chain 14 on both sides is hung on the hook 17 of the first safety guardrail 131, so that the protective chain 14 is basically taut, ensuring the safety of the operator.

[0059] 4) After the welding operation is completed, the sub-platform 13 is retracted into the main platform 12, the lifting platform is lowered to the lowest position by the scissor arm 16, and the two second driving mechanisms drive the lifting platform to move away from the positioner 2 and the workpiece 3.

[0060] In summary, the positioner lifting platform of the present application increases the sub-platform in the main platform, the sub-platform extends and retracts through the guide rail welded in the main platform, increases the operation range of the operator, avoids the interference between the lifting platform scissor arm and the workpiece, and the accessibility of the manually welded workpiece is better, and the operation range of the operator is larger. Moreover, the operator does not need to climb over the safety guardrail to stand on the workpiece for welding, avoiding the risk of falling from a great height, and there is no safety hazard. The length of the guide rail installed in the main platform can be adjusted according to the operation requirement length of the sub-platform, increasing the operation coverage range of the lifting platform. The protective chain is provided on both sides of the sub-platform, which can be adjusted according to the extension length of the sub-platform, ensuring the safety of the operator and having the flexibility of operation. In addition, the positioner lifting platform of the present application is equipped with two driving motors for driving walking, so that the two walking wheels are evenly stressed, the lifting platform walks more stably, and the risk of derailment is avoided.
