The utility model is described in detail below in combination with the drawings.
[0018] As shown in Figure 1 and Figure 2 The utility model provides a kind of hoisting type screw locking mechanism, including portal frame 1, be set to the driving module 2 of portal frame 1 and be slidably set to the screw locking module 3 of portal frame 1, driving module 2 is used to drive screw locking module 3 along portal frame 1 to and fro movement, the portal frame 1 has cross beam 4, the bottom of cross beam 4 is provided with guide rail 41, and screw locking module 3 is slidably set to guide rail 41.
[0019] In the prior art, the guide rail 41 is usually arranged on the top or one side of the cross beam 4 of the gantry 1, and no matter which case, the part of the lock screw module 3 sliding on the guide rail 41 is necessarily located on one side of the lock screw module 3, which causes the lock screw module 3 to be unbalanced and requires more space 42.
[0020] However, the guide rail 41 is arranged at the bottom of the cross beam 4, and the lock screw module 3 directly slides on the guide rail 41, and the stability of sliding is ensured because the lock screw module 3 is not arranged eccentrically on one side, so that high-speed operation of the lock screw module 3 can be realized; in addition, the lock screw module 3 is arranged in the gantry 1, and more space 42 is not required on both sides of the gantry 1 for the movement of the lock screw module 3, so that the requirement for the space 42 is reduced, and the utilization rate of the space 42 is improved.
[0021] In the embodiment, the number of the guide rails 41 is two, and the two guide rails 41 are arranged at the bottom of the cross beam 4 in parallel and at intervals, and the lock screw module 3 is provided with two slider modules, and the two slider modules are in one-to-one sliding connection with the two guide rails 41.
