Description

Technical Field

[0001] The utility model relates to the field of mounting platform design, in particular to a lifting mounting platform. Background Art

[0002] The elevator is a kind of lifting equipment consisting of a traveling mechanism, a hydraulic mechanism, an electric control mechanism, and a supporting mechanism.

[0003] At present, the inner wall of a conventional elevator is provided with an outer scissor frame and an inner scissor frame for staggered lifting. The outer scissor frame and the inner scissor frame cooperate with each other to flip in reverse, so as to push the lifting plate on the top to lift and lower. A hydraulic rod is provided inside the outer scissor frame and the inner scissor frame, and the hydraulic rod is hinged to the connecting rod inside the outer scissor frame and the inner scissor frame. When the hydraulic rod pushes the connecting rod, the connecting rod will be subjected to force to push the outer scissor frame and the inner scissor frame to flip and lift.

[0024] The utility model provides Figure 1-6 The lifting installation platform shown in the figure includes a connecting platform 1, a lifting frame 101 is provided on the top of the connecting platform 1, and further includes:

[0025] The lifting assembly includes an inner scissor frame 201 provided at the top of the lifting frame 101, an outer scissor frame 2 is hingedly connected to the wall of the inner scissor frame 201, a plurality of rotating shafts 402 are provided at the connection between the outer scissor frame 2 and the inner scissor frame 201, a hydraulic unit 3 for pushing the inner scissor frame 201 up and down is provided at the bottom end of the inner scissor frame 201, and a lifting plate 102 is hingedly connected to the top of the outer scissor frame 2;

[0027] It should be noted that when the hydraulic unit 3 is started, the inner scissor frame 201 and the outer scissor frame 2 will both rotate with the rotating shaft 402 as the center, the inner scissor frame 201 will rotate clockwise, and the outer scissor frame 2 will rotate counterclockwise. During the rotation, the bottom end of the outer scissor frame 2 will slide on the top of the lifting frame 101, and the top of the inner scissor frame 201 will slide on the bottom end of the lifting plate 102. The lifting and lowering of the lifting plate 102 is achieved through the mutual cooperation of the inner scissor frame 201 and the outer scissor frame 2.

[0028] Specifically, the top end of the lifting frame 101 is hinged to the bottom end of the inner scissors frame 201, and a plurality of guide wheels 4 are provided at the bottom end of the outer scissors frame 2. A plurality of guide rail frames 401 are provided at the top end of the lifting frame 101 and at one end close to the outer scissors frame 2. The top ends of the plurality of guide rail frames 401 are slidingly connected to the bottom ends of the plurality of guide wheels 4, and the bottom end of the lifting plate 102 is slidingly connected to the top end of the inner scissors frame 201.

[0029] It should be noted that the working principles of the inner scissor frame 201 and the outer scissor frame 2 are the same as the moving parts of the cross-type elevator model SJT. A hinged seat is provided on one side of the lifting frame 101 and the lifting plate 102. The hinged seat at the top of the lifting frame 101 is hinged to the bottom end of the inner scissor frame 201, and the hinged seat at the bottom end of the lifting plate 102 is hinged to the top of the outer scissor frame 2. When the inner scissor frame 201 rotates, the guide wheel 4 will slide on the top of the guide frame 401, and a roller plate is provided at the bottom end of the lifting plate 102, and a roller is provided at the top of the outer scissor frame 2. During the lifting and lowering process of the lifting plate 102, the roller will slide on the inner wall of the roller plate.

[0030] Specifically, the hydraulic part 3 includes a hydraulic rod 301 and a first lifting ear 302. The top ends of the multiple hydraulic rods 301 are hinged to the inner walls of the multiple first lifting ears 302. An external connecting rod 304 is provided on the inner wall of the inner scissors frame 201 and at one end close to the rotating shaft 402. Multiple first lifting ears 302 are provided on the outer wall of the inner connecting rod 202. An external connecting rod 304 is provided on the inner wall of the outer scissors frame 2 and at one end close to the lifting frame 101. A second lifting ear 303 is provided on the outer wall of the external connecting rod 304. The top end of the second lifting ear 303 is hinged to the output end of the hydraulic rod 301.

[0031] It should be noted that the working principle of the hydraulic rod 301 and the first lifting ear 302 is the same as the pushing part of the cross-type lift model SJT. When rising on the lifting plate 102, the hydraulic rod 301 needs to be retracted. The hydraulic rod 301 will pull the inner connecting rod 202 through the second lifting ear 303, so that the inner connecting rod 202 drives the inner scissors frame 201 to rotate. At the same time, the hydraulic rod 301 will pull the inner connecting rod 202 through the first lifting ear 302, and the inner connecting rod 202 pulls the inner scissors frame 201 to rotate.

[0032] Specifically, the outer walls of the multiple fixing bolts 502 are connected to the internal threads of the multiple main fixing plates 5, and the ends of the multiple fixing bolts 502 away from the main fixing plates 5 are sleeved with multiple fixing rings 503. The ends of the multiple fixing bolts 502 away from the fixing rings 503 are threadedly connected to the inner walls of the multiple auxiliary fixing plates 501, and the ends of the multiple fixing bolts 502 away from the auxiliary fixing plates 501 are threadedly fitted with fixing nuts 504.

[0033] It should be noted that the outer wall of the outer scissors frame 2 is provided with a locking hole and a locking rod. When the main fixing plate 5 is not working, the operator needs to rotate the main fixing plate 5 to the locking hole position with the rotating shaft 402 as the center, and use the locking rod to insert the main fixing plate 5 through the outside of the outer scissors frame 2 to achieve locking. When the lifting plate 102 moves to the top, the operator needs to take out the locking rod and loosen the main fixing plate 5 to rotate the rotating shaft 402 to a vertical angle. Finally, the main fixing plate 5 will be docked with the auxiliary fixing plate 501, and the fixing bolt 502 will be inserted through the outer walls of the main fixing plate 5 and the auxiliary fixing plate 501. When the thread is inserted, the fixing ring 503 needs to be placed in the gap position between the main fixing plate 5 and the auxiliary fixing plate 501, and finally the fixing nut 504 is threadedly fitted on one end of the fixing bolt 502 to fix it.

[0034] Working principle of this utility model:

[0035] The specific operation is that the operator needs to start the hydraulic rod 301 when performing the lifting operation. The output end of the hydraulic rod 301 will push the outer connecting rod 304. The outer connecting rod 304 will drive the outer scissors frame 2 to rotate clockwise with the rotating shaft 402 as the center under the push of the hydraulic rod 301 through the hinge. During the rotation of the outer scissors frame 2, the guide wheel 4 at the bottom end will be forced to slide on the top of the guide rail frame 401. At the same time, the inner connecting rod 202 will be subjected to the reaction force of the hydraulic rod 301 to push the inner scissors frame 201, and the inner scissors frame 201 will rotate counterclockwise with the rotating shaft 402 as the center. When the outer scissors frame 2 and the inner scissors frame 201 rotate, their top ends will expand and fall outward, and the outer scissors frame 2 and the inner scissors frame 201 will rotate counterclockwise. 1 will drive the lifting plate 102 to fall, and the operator will retract the hydraulic rod 301 in the same way, and the outer scissor frame 2 and the inner scissor frame 201 will rotate in opposite directions with the rotation axis 402, and the top ends of the outer scissor frame 2 and the inner scissor frame 201 will also drive the lifting plate 102 to rise. When the lifting plate 102 rises to the top end, the operator can rotate the main fixing plate 5 through the rotation axis 402, and dock the main fixing plate 5 with the auxiliary fixing plate 501 and keep them in the same straight line position, thread the fixing bolt 502 through the connection between the main fixing plate 5 and the auxiliary fixing plate 501, and finally fix the fixing bolt 502 at the connection between the main fixing plate 5 and the auxiliary fixing plate 501 through the fixing nut 504 to achieve locking.
