SUMMARY

[0004] The utility model provides a kind of balance beam stop mechanism for suspension chain conveying line, which can avoid the retreat of balance beam, ensure the accuracy of workpiece position, and solve the problem that balance beam deviates from specified position after being stopped by stopper.

[0005] In order to achieve the above object, the utility model discloses the following technical scheme: a kind of balance beam stop mechanism of suspension chain conveying line of the utility model, including overhead track, balance beam and slide frame, the slide frame is slidably arranged on overhead track, the balance beam is hung in the bottom of slide frame, gravity rack is hinged on the overhead track, one-way tooth is arranged at interval on the gravity rack, the gap between the one-way tooth forms stop tooth groove, the slide frame is equipped with the stop reverse baffle strip that is adapted to stop tooth groove, when gravity rack is in natural state, the higher end of gravity rack is pressed against overhead track.The overhead track, balance beam and slide frame in the utility model are all conventional structure in the art, pulley or roller is installed on slide frame, so that slide frame moves along overhead track under the drive of conveying chain;When stop reverse baffle strip slides through gravity rack, gravity rack will be lifted, so that slide frame moves balance beam to specified position, when balance beam moves to specified position, balance beam is stopped by stopper at this place and advances, when stop reverse baffle strip is inserted into stop tooth groove on gravity rack, stop reverse baffle strip is limited by gravity rack and cannot retreat, so that balance beam can be in specified position;After workpiece is handled, stopper avoids balance beam, and slide frame is driven forward by conveying chain.

[0006] Preferably, the overhead track is fixed with a hinged seat, and the gravity rack is hinged to the hinged seat.

[0007] Preferably, the hinged seat comprises a U-shaped fixed plate, the U-shaped fixed plate is fixedly connected with the overhead track, a pair of hinged ear plates are arranged at the bottom of the U-shaped fixed plate, and the gravity rack is hinged to the hinged ear plates. When the gravity rack is in a natural state, the higher end of the gravity rack is pressed against the bottom of the U-shaped fixed plate. The opening of the U-shaped fixed plate can be just clamped into the overhead track, facilitating installation and adjustment of the installation position, and having good stability.

[0008] Preferably, the hinged seat further comprises a hinged bolt, the hinged bolt passes through the hinged ear plates and the gravity rack, and the gravity rack is hinged to the hinged ear plates by the hinged bolt. The gravity rack is hinged to the hinged ear plates by the hinged bolt, which is simple in structure and convenient to disassemble and assemble.

[0009] Preferably, the U-shaped fixed plate is fastened to the overhead track as a whole by screws.

[0010] Therefore, the utility model has the following beneficial effects: through cooperation of the gravity rack and the stop reverse baffle strip, the stop reverse baffle strip is limited by the gravity rack and cannot retreat after the balance beam reaches the specified position, so that the balance beam can be in the specified position, which is simple in structure, high in practicability, can avoid retreat of the balance beam, and ensures accuracy of the position of the workpiece. BRIEF DESCRIPTION OF DRAWINGS

[0016] The utility model will be further described in combination with the drawings and specific embodiments.

[0017] As Figure 1 , Figure 2 shown in the figure, a kind of balance suspension beam anti-back mechanism of suspension chain conveying line, including overhead track 1, balance suspension beam 2 and sliding frame 3, sliding frame is slidably arranged on overhead track, balance suspension beam is hung in the bottom of sliding frame, hinged seat 8 is fixed on overhead track, hinged seat includes U-shaped fixed plate 9 and hinged bolt 11 (as Figure 3 , Figure 4 shown), U-shaped fixed plate is fixedly connected with overhead track by screw, a pair of hinged lug plate 10 is equipped in the bottom of U-shaped fixed plate, gravity rack 4 is equipped on the outside of hinged lug plate, hinged bolt passes through hinged lug plate and gravity rack, gravity rack is hinged with hinged lug plate by hinged bolt, when gravity rack is in natural state, higher end of gravity rack is against the bottom of U-shaped fixed plate, one-way tooth 5 is equipped at interval on gravity rack, clearance between one-way tooth forms anti-back tooth groove 6, anti-reverse stop bar 7 that is adapted to anti-back tooth groove is fixed on sliding frame.

[0018] The working principle of the utility model is as follows: sliding frame drives balance suspension beam to move along overhead track synchronously under the drive of conveying chain, when anti-reverse stop bar slides through gravity rack, gravity rack is lifted up (gravity rack rotates counterclockwise with hinged point as the shaft), so that sliding frame can move forward, when balance suspension beam moves to specified position with sliding frame, balance suspension beam is stopped by stopper (not shown in the figure) at this place and stops advancing, gravity rack falls down at this time, so that anti-reverse stop bar is clamped into anti-back tooth groove on gravity rack (as Figure 2 shown), anti-reverse stop bar cannot retreat under the limitation of gravity rack (higher end of gravity rack is against the bottom of U-shaped fixed plate and cannot rotate clockwise), so that balance suspension beam can be in specified position.

[0019] The above-described embodiments are only a preferred scheme of the present application, and do not limit the present application in any form, and other variations and modifications are possible without departing from the technical scheme recited in the claims.
