Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
In embodiments of the invention, where the context requires otherwise, the use of directional terms such as "upper, lower, top and bottom" is generally intended in the orientation shown in the drawings or the positional relationship of the various components in a vertical, vertical or gravitational orientation.
The invention will be described in detail below with reference to exemplary embodiments and with reference to the accompanying drawings.
Referring to fig. 1 to 3, a first exemplary embodiment of the present invention provides a lifting mechanism 1 including a fixed frame 11, a lifting frame 12, a first double lever folding mechanism 13, a second double lever folding mechanism 14, and a cam driving mechanism.
Specifically, the fixing frame 11 is a supporting component of the jacking mechanism 1, and plays a role of supporting the upper part of the jacking mechanism, so that the jacking mechanism 1 is integrally stable. The jacking frame 12 plays a role in supporting the truss arm sections, and the jacking frame 12 and the fixing frame 11 are arranged at intervals up and down.
The first double bar folding mechanism 13 and the second double bar folding mechanism 14 define a first angle and a second angle, respectively, which are arranged along the transverse reverse opening. Thus, the first dual-rod folding mechanism 13 and the second dual-rod folding mechanism 14 can be placed in two ways, namely, the first included angle and the second included angle are arranged along the openings facing in the transverse direction (see fig. 1), and the first included angle and the second included angle are arranged along the openings facing in the transverse direction (not shown). The synchronous expansion of first two-bar folding mechanism 13 and second two-bar folding mechanism 14 can both be realized to two kinds of condition, realizes in the jacking process of climbing mechanism 1, and the purpose that jacking frame 12 can balanced vertical rising is avoided jacking frame 12 to take place to incline for the horizontal plane when rising and lead to by the truss arm section sliding weight of jacking.
In addition, the upper end and the lower end of the first double-rod folding mechanism 13 are respectively hinged to the jacking frame 12 and the fixing frame 11, and the upper end and the lower end of the second double-rod folding mechanism 14 are also respectively hinged to the jacking frame 12 and the fixing frame 11. The first double-rod folding mechanism 13, the second double-rod folding mechanism 14, the jacking frame 12 and the fixed frame 11 together form a frame structure of the jacking mechanism 1.
The cam driving mechanism is a movement force transmission mechanism of the whole jacking mechanism 1 and can drive the first double-rod folding mechanism 13 and the second double-rod folding mechanism 14 to synchronously displace, so that the jacking frame 12 gradually rises in the process that the first included angle and the second included angle are synchronously increased.
Through setting up above-mentioned structure, when the truss arm festival need break away from the supporting bench of assembly line, accessible cam actuating mechanism drive first double-rod folding mechanism 13 and the synchronous displacement of second double-rod folding mechanism 14 so that first contained angle and the synchronous increase of second contained angle to drive jacking frame 12 and rise gradually, with this lifting truss arm festival, break away from the supporting bench until the truss arm festival. Adopt climbing mechanism 1 of this exemplary embodiment in the truss arm assembly line, can let the truss arm festival in time break away from a supporting bench to avoid the assembly line to stop the line and wait to produce, improve the rate of utilization of assembly line and the production efficiency of truss arm festival, and under the supporting bench is the condition of rolling a supporting bench, through jacking truss arm festival, still can reduce truss arm festival slide and weigh down the risk, improve the security, avoid the work piece to collide with the damage.
Of course, the jacking mechanism 1 of the present exemplary embodiment can also be used in other situations where it is necessary to jack an object or a workpiece, and is not limited to being used in a truss arm line.
Further, as shown in fig. 1, the cam driving mechanism may include a cam 15, a follower washer 16, and a link rail 17. Specifically, one end of the link rail 17 is connected to the first dual lever hinge shaft 131 of the first dual lever folding mechanism 13, and the other end thereof slidably passes through the second dual lever hinge shaft 141 of the second dual lever folding mechanism 14. In this way, in the process of synchronous increase or synchronous decrease of the first and second included angles, the linkage cross bar 17 is always kept in a transverse arrangement through the fixed connection with the first dual-bar hinge shaft 131 and the movable connection with the second dual-bar hinge shaft 141, and the second dual-bar hinge shaft 141 can slide on the linkage cross bar 17.
Further, the cam 15 is rotatably connected to the link rail 17, i.e., the hinge point of the cam 15 in the link rail 17 is fixed in position but is rotatable. The follower washer 16 slidably passes through the link rail 17 and is crimped between the cam 15 and the angled tip portion 142 of the second dual bar folding mechanism 14. For the frame structure formed by the first double-rod folding mechanism 13, the second double-rod folding mechanism 14, the jacking frame 12 and the fixed frame 11, the driven washer 16 can be always kept pressed by the cam 15 and the included angle tip part 142 under the action of the gravity of the jacking frame 12.
In order to realize the jacking driving, a part of the cam circumferential contour line is required to be set to be a jacking contour line with an increasing curvature radius, namely, the cam radius is correspondingly increased within the range of the formed jacking contour line with the increasing curvature radius, so that the jacking frame 12 can be gradually lifted in the process of rotating the cam 15 to enable the driven washer 16 to slide along the jacking contour line with the increasing curvature radius.
In other words, a specific jacking driving principle of the cam driving mechanism is as follows:
rotate cam 15 with the direction that increases progressively in reverse jacking outline line curvature radius, make driven packing ring 16 slide along the jacking outline line that curvature radius increases progressively, at this moment, driven packing ring 16 can slide along the direction that linkage horizontal pole 17 orientation is close to contained angle pointed end 142, thereby can form the extrusion to two pole folding mechanism 14 of second, make the second contained angle increase, and simultaneously, linkage horizontal pole 17 can move towards the opposite direction of motion with driven packing ring 16, thereby stimulate first two pole folding mechanism 13, make first contained angle synchronous increase, therefore, realize first contained angle and the synchronous crescent of second contained angle promptly, thereby drive jacking frame 12 balanced rising gradually.
Referring to fig. 1, the first included angle opening is disposed opposite to the second included angle opening, and the cam 15 is rotatably connected to one end of the link cross bar 17 passing through the second double-bar hinge shaft 141. That is, one end of the link rail 17 is fixedly coupled to the first dual lever hinge shaft 131 and the other end is connected to the rotatable cam 15. So, when adopting manual mode control climbing mechanism 1 when jacking with truss arm section jack-up, the workman can be at the line limit control cam 15 of assembly line, and operating space is big, and the workman can not put in truss arm section below, and the security is higher.
Of course, it can be achieved in other ways than by providing the linkage crossbar 17 to assist in achieving the synchronized displacement of the first and second double bar folding mechanisms 13, 14. For example, the crimping driving of the cams 15 can be implemented by providing the respective angle tips of the first dual-bar folding mechanism 13 and the second dual-bar folding mechanism 14, and to ensure that the two cams 15 rotate synchronously, the rotation can be driven by a motor in cooperation with a controller.
Referring to fig. 2, the cam 15 may be formed in a clip shape and includes a first cam side plate 151, a second cam side plate 152, and a cam rotating shaft 153, wherein the first cam side plate 151 and the second cam side plate 152 are disposed in parallel at an interval, and both ends of the cam rotating shaft 153 are fixedly connected to the first cam side plate 151 and the second cam side plate 152, respectively. In addition, the cam rotating shaft 153 penetrates the interlocking cross bar 17, and the interlocking cross bar 17 is partially penetrated into the balance interval regions of the first cam side plate 151 and the second cam side plate 152.
By providing the cam 15 in the form of a clip, it is possible to rotate the cam 15 without interfering with the normal movement of the link lever 17. Of course, the structure of the cam 15 is not limited as long as the cam 15 can meet the requirement that some cam circumferential contour lines are formed into jacking contour lines with gradually increased curvature radiuses, and when the cam 15 is rotated, the linkage cross rod 17 can be driven to move without influencing the normal movement of the linkage cross rod 17. For example, the cam 15 may also include a cam side plate and a cam shaft 153, one end of the cam shaft 153 is fixedly connected to the cam side plate, and the other end of the cam shaft 153 is rotatably connected to the linkage cross bar 17, so that when the cam 15 is rotated, the normal movement of the linkage cross bar 17 is not affected.
Referring to fig. 1, the cam driving mechanism includes a rocker handle 18 fixedly connected to the cam 15 for driving the cam 15 to rotate, i.e., the cam 15 can be rotated by pulling the rocker handle 18. The rocker handle 18 may be pulled by a manual pull or by an automated device.
For example, the cam 15 may be driven to rotate by a worker manually pulling the rocker handle 18 to allow the jacking frame 12 to rise in balance to allow the truss arm section to be detached from the support platform 2, during which time the worker may steady the rocker handle 18 with his or her hand to maintain the height of the jacking frame 12. After the truss arm section is transferred from the jacking frame 12, a worker can release the rocker handle 18, the jacking frame 12 descends and resets under the self-weight drive of the jacking frame 12, and the second double-rod hinge shaft 141, the cam 15, the driven washer 16 and the linkage cross rod 17 are adaptively moved and reset in the resetting process.
Or, the rocker handle 18 can be pulled by an automatic device to drive the cam 15 to rotate, and when the jacking frame 12 rises to the target height, the automatic device can be self-locked to keep the height of the jacking frame 12. After the truss arm section is transferred, the automation equipment is unlocked and the rocker handle 18 is pulled reversely, so that the jacking frame 12 is lowered and reset.
Continuing to refer to fig. 1, the fixed frame 11 may include a fixed cross rod 111 and a vertical guide post 112 extending upward from the fixed cross rod 111, the jacking frame 12 may include a jacking cross rod 122 and a guide sleeve 121 extending downward from the jacking cross rod 122, the vertical guide post 112 may be slidably inserted into the guide sleeve 121, so as to guide in the lifting process of the jacking frame 12, ensure that the jacking frame 12 ascends or descends in a balanced manner, and improve the stability of the jacking mechanism 1.
Further, the fixing frame 11 may further include a cross bar supporting structure connected to the peripheral wall of the vertical guiding bar 112 and supporting the linkage cross bar 17, wherein the cross bar supporting structure is used to strengthen the supporting of the linkage cross bar 17, so that the linkage cross bar 17 is kept horizontal.
For example, the cross bar support structure may comprise an L-shaped bar comprising an L-shaped bar transverse section and an L-shaped bar vertical section, the two ends of the L-shaped bar transverse section being connected to the L-shaped bar vertical section and the peripheral wall of the vertical guide bar 112, respectively, such that the L-shaped bar vertical section is spaced apart from the vertical guide bar 112. In addition, the linkage cross rod 17 penetrates through a spacing area between the L-shaped rod vertical section and the guide vertical rod 112, and the L-shaped rod horizontal section forms a reinforcing support for the linkage cross rod 17. In the jacking process, the interval area between the vertical section of the L-shaped rod and the vertical guide rod 112 provides a moving space for the linkage cross rod 17.
Of course, the cross bar support structure can be configured as other forms besides the L-shaped bar, as long as it can play a role in strengthening and supporting the linkage cross bar 17, and it does not affect the movement of the linkage cross bar 17.
On the other hand, the fixing frame 11 may further include a suspension fixing structure for suspending and fixing the jacking mechanism 1, and the jacking mechanism 1 is fixedly connected with the supporting table 2 through the suspension fixing structure to realize suspension arrangement.
Referring to fig. 1 and 2, the suspended fixing structure includes a first external cross plate 113 and two second external cross plates 114. The first external transverse plate 113 is fixedly connected to the vertical guiding rod 112, and the two second external transverse plates 114 are respectively vertically connected to two ends of the first external transverse plate 113 and extend along the transverse direction.
For example, when the jacking mechanism 1 is applied to a truss arm production line, referring to fig. 4 and 5, the jacking mechanism 1 can be suspended and fixedly arranged by fixedly connecting two second external cross plates 114 to two support tables 2 arranged at intervals in the width direction of the production line respectively.
The second exemplary embodiment of the present invention also provides a truss arm assembly line including a plurality of support tables 2 and a plurality of jacking mechanisms 1. A plurality of support tables 2 are used to support the truss arm sections, which may be rolling support tables, for example. The plurality of jacking mechanisms 1 are used for jacking the truss arm sections to be separated from contact with the plurality of supporting tables 2.
Referring to fig. 4 to 5, the truss arm assembly line may include a plurality of truss arm joint support groups sequentially arranged at intervals in the length direction of the flow line, and each truss arm joint support group includes two support tables 2 arranged at intervals in the width direction of the flow line and a jacking mechanism 1 arranged in the width direction of the flow line and connected to the two support tables 2.
So set up, when the truss arm festival finishes and need break away from the assembly line, can carry out the jacking to the truss arm festival through climbing mechanism 1, make it break away from a plurality of brace tables 2 to solve the truss arm festival that finishes in truss arm assembly line production process and can't break away from brace table 2 scheduling problem, because the aforesaid has the concrete description of relevant effect, repeated description is no longer repeated here.
