Description

Technical Field

[0001] This utility model relates to the field of mechanical conveying technology, and in particular to a rail support mechanism. Background Technology

[0002] The skateboard lift can be raised and lowered by a drive mechanism. After the skateboard lift is lowered to the lowest position or raised to the highest position, it needs to be fixed to make the skateboard lift more stable.

[0003] Existing fixing mechanisms primarily use cylinders or similar devices to move a guide rod to a guide seat for fixation. The guide rod engages with a through hole in the guide seat. If there is even a slight deviation, the skateboard lift frame needs to be repositioned so that the guide rod can re-enter the through hole for fixation. Furthermore, the guide rod must bear the weight of the entire skateboard lift frame, placing a significant burden on it and making it prone to deformation due to excessive stress, thus affecting its usability.

[0004] Therefore, we propose a track-supporting mechanism. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a rail support mechanism that uses a motor to drive the rotation of the shaft to lock and separate the arc-shaped locking rod and the locking seat, thereby achieving the locking and unlocking of the skateboard lifting frame.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A rail-supporting mechanism, comprising:

[0008] The rotating shaft is fixedly connected to the output shaft of the motor, and the motor is fixed to the bottom of the skateboard lifting frame;

[0009] The first rotating arm is fixed on the rotating shaft;

[0010] The second rotating arm has one end rotatably connected to the connecting rod, and the other end of the second rotating arm is rotatably connected to the mounting base, which is fixed to one side of the sliding plate lifting frame.

[0011] The locking seat is fixed to the ground, and an arc-shaped groove is provided on the side of the locking seat near the second rotating arm.

[0012] The other end of the connecting rod is rotatably connected to the first rotating arm, and the rotating shaft is driven to rotate by the motor, thereby driving the first rotating arm, the connecting rod and the second rotating arm to rotate.

[0013] The second rotating arm is L-shaped, and an arc-shaped locking rod is provided at the turning point of the second rotating arm. The arc-shaped locking rod can move into the arc-shaped groove of the locking seat to lock the skateboard lifting frame.

[0014] Its further features are:

[0015] The rotating shaft is mounted on the mounting beam and can rotate relative to the mounting beam, which is fixed to the sliding plate lifting frame.

[0016] The rotating shaft is mounted on the mounting beam via a bearing housing.

[0017] The motor is fixed to the mounting beam, and the motor is fixed to the sliding plate lifting frame through the mounting beam.

[0018] The beneficial effects of this utility model are as follows:

[0019] This utility model has a compact and reasonable structure and is easy to operate. When the skateboard lifting frame moves to the lowest or highest position, it needs to be locked. The motor rotates forward, and the output shaft of the motor drives the rotating shaft to rotate. The rotating shaft drives the first rotating arm to move towards the locking seat. The first rotating arm drives the second rotating arm to move through the connecting rod until the arc-shaped locking rod on the second rotating arm enters the arc-shaped groove in the locking seat, thus completing the locking of the lifting frame. The whole structure is simple and reliable, and can quickly lock and unlock the skateboard lifting frame.

[0020] In addition, this utility model also has the following advantages:

[0021] (1) When the skateboard lift needs to move, the motor reverses and the output shaft of the motor drives the rotating shaft to rotate. The rotating shaft drives the first rotating arm to move away from the locking seat. The first rotating arm drives the second rotating arm to move through the connecting rod. The second rotating arm leaves the locking seat and no longer locks the skateboard lift. The skateboard lift can be driven to move through the drive mechanism. Attached Figure Description

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0028] like Figures 1-4 As shown, a rail support mechanism includes a mounting beam 1, a rotating shaft 2, a motor 3, a first rotating arm 4, a connecting rod 5, a second rotating arm 6, a mounting base 7, an arc-shaped locking rod 8, and a locking seat 9.

[0029] Mounting beam 1 is fixed below the skateboard lift frame 10, and mounting base 7 is fixed on one side of the skateboard lift frame 10.

[0030] The rotating shaft 2 is mounted on the mounting beam 1, and the rotating shaft 2 can rotate relative to the mounting beam 1.

[0031] In one embodiment, the rotating shaft 2 is mounted on the mounting beam 1 via a structure such as a bearing housing.

[0032] The motor 3 is fixed on the mounting beam 1, and the output shaft of the motor 3 is fixed to the rotating shaft 2. When the motor 3 is working, the output shaft of the motor 3 can drive the rotating shaft 2 to rotate.

[0033] The first rotating arm 4 is fixed on the rotating shaft 2. The rotation of the rotating shaft 2 can drive the first rotating arm 4 to rotate. The other end of the first rotating arm 4 is rotatably connected to the connecting rod 5. The other end of the connecting rod 5 is rotatably connected to one end of the second rotating arm 6. The other end of the second rotating arm 6 is rotatably connected to the mounting base 7.

[0034] In one embodiment, the second swing arm 6 is L-shaped, and an arc-shaped locking rod 8 is provided at the turning point of the second swing arm 6.

[0035] The locking seat 9 is set on the ground. The side of the locking seat 9 near the second rotating arm 6 is provided with an arc-shaped groove 901, and the arc-shaped locking rod 8 can enter the arc-shaped groove 901.

[0036] like Figure 3 As described above, when the skateboard lift frame 10 needs to move, the motor 3 reverses, and the output shaft of the motor 3 drives the rotating shaft 2 to rotate. The rotating shaft 2 drives the first rotating arm 4 to move away from the locking seat 9. The first rotating arm 4 drives the second rotating arm 6 to move through the connecting rod 5. The second rotating arm 6 leaves the locking seat 9 and no longer locks the skateboard lift frame 10. The skateboard lift frame 10 can be driven to move through the drive mechanism.

[0037] like Figure 4 As described above, when the skateboard lifting frame 10 moves to its lowest or highest position, it needs to be locked. The motor 3 rotates forward, and the output shaft of the motor 3 drives the rotating shaft 2 to rotate. The rotating shaft 2 drives the first rotating arm 4 to move towards the locking seat 9. The first rotating arm 4 drives the second rotating arm 6 to move through the connecting rod 5 until the arc-shaped locking rod 8 on the second rotating arm 6 enters the arc-shaped groove 901 in the locking seat 9, thus completing the locking of the lifting frame 10. The whole structure is simple and reliable, and can quickly lock and unlock the skateboard lifting frame 10.
