As shown in fig. 1 and 2, the limiting guide seat of the utility model comprises a lifting frame and a portal frame; the center of the lifting frame 9 is vertically provided with a guide seat through a reinforcing rib, the top of the guide seat is sleeved with a hard arm mechanism, the top of the hard arm mechanism is vertically lifted at the bottom of a roadway through a portal frame 7, a driving part arranged in the portal frame 7 is controlled and driven by a guide wheel set arranged on an upper bearing arm and a lower bearing arm through a transmission rack, a butt joint end at the bottom of the lower bearing arm is in transmission butt joint with a hanging ring 1 at the top of the guide seat, the hanging ring 1 is horizontally limited and connected with a hanging rod 2 through a circular base arranged at the bottom, the hanging rod 2 is vertically inserted in a guide sleeve 3, the guide sleeve 3 is inserted into a stepped hole at the center of a flange 6 along the vertical direction, the guide sleeve is transversely provided with a horizontal through hole along the joint end part of the flange 6 and the guide sleeve 3, a fixed seat 5 is inserted in the horizontal through hole, and a micro switch 4 is transversely arranged in the fixed seat 5, the microswitch 4 is selectively in pressing contact with the end face of the bottom of the suspender 2. The lifting plate is fixed at a designated place by the worker through the lifting chain matched with the lifting ring, and the lifting chain and the lifting ring are on the same vertical line, so that the lifting chain is matched with the guide seat to complete the lifting guide process. And the guide sleeve 3 as the guide fixing equipment plays an integral limiting role and can limit the hanger rod 2 to move only in the vertical direction. Therefore, the suspension rod 2 is matched with the microswitch 4 to be selectively contacted in the falling process, and the hoisting equipment is matched to make a high-precision starting instruction.

As shown in fig. 1 and 2, an electrical signal output end of the microswitch 4 is transmitted to a signal receiving end of the drive controller through a line, and an elastic contact piece is mounted at the top of the microswitch 4 and is selectively pressed and contacted with the end surface of the bottom of the suspension rod 2. The microswitch 4 is matched with the hanger rod 2 to fall and extrude, and the elastic contact piece is touched, so that the microswitch 4 and the elastic contact piece are in a disconnected state, the electric signal can be transmitted to a signal receiving end of the driving controller, and the lifting appliance is directly and passively started by system processing to complete a lifting process; simultaneously, transfer the process and also can utilize the natural gravity extrusion micro-gap switch 4 elastic contact piece of jib 2, let micro-gap switch 4 and elastic contact piece be in the closed condition to the action of transferring of the hoist stops in the very first time.

As shown in fig. 1 and 2, a stepped cavity is formed in the inner wall of the guide sleeve 3, the cross section of the stepped cavity is of an inverted T-shaped structure, and the radius of the root of the stepped cavity is larger than that of the top of the stepped cavity. Wherein, the step chamber of the guide sleeve 3 with the inverted T-shaped structure can limit the motion range of the suspender 2, thereby reducing the reaction time of the equipment and delaying the durability of the equipment.

As shown in fig. 1 and 2, the stepped chamber at the root is in clearance fit with the end at the bottom of the suspender 2, and the stepped chamber at the top is in a non-contact state with the top shaft of the suspender 2. The end of 2 bottoms of jib and the ladder cavity clearance fit of root can avoid the end of 2 bottoms of jib to lead to the unable accurate touching of center slope or extrusion elastic contact piece because of the space is too big to lead to the unable normal operating of equipment. The ladder chamber at the top in the non-contact state and the suspender 2 can avoid unnecessary contact, and the effect of prolonging the service life of the suspender 2 is achieved.
