[0011] (III) Beneficial effects

[0012] The beneficial effects of the utility model are:

[0013] (1) During operation, the elevator guide rail is placed in the wheel groove, and the tightening mechanism drives the second limiting wheel to move to the left, so that the second limiting wheel is directly in close contact with the side wall of the elevator guide rail, and at the same time cooperates with the first limiting wheel to clamp the entire elevator guide rail.

At the same time, the processing mechanism starts to work to punch holes in the elevator guide rail, which solves the problem of low processing efficiency in the current punching process of the elevator guide rail bracket, which is usually performed by using a punching machine to punch multiple holes one by one.

[0014] (2) The turn plate rotates counterclockwise, driving the push wheel to rotate counterclockwise, until the push wheel surface is in close contact with the mounting plate surface. At this time, the turn plate continues to rotate counterclockwise, driving the push wheel to continue to rotate counterclockwise.

[0016] (4) When unlocking is required, the lifting plate is pushed upward, and the lifting plate moves upward, driving the locking rod to move upward. The locking claw can be disengaged from the ratchet to complete unlocking. At this time, due to the spring force of the second return spring, the rotating plate is driven to rotate clockwise, so that the second limit wheel no longer presses the mounting plate, so that the first limit wheel and the second limit wheel no longer clamp the elevator guide rail. At this time, the distance between the first limit wheel and the second limit wheel can be readjusted according to the size of the elevator guide rail. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] It should be noted that, when working, the elevator guide rail 2 is placed in the wheel groove 4, and the tightening mechanism 11 drives the second limiting wheel 7 to move to the left, so that the second limiting wheel 7 is directly in close contact with the side wall of the elevator guide rail 2, and at the same time cooperates with the first limiting wheel 6 to clamp the entire elevator guide rail 2, and the active roller 5 rotates to drive the elevator guide rail 2 to move forward along the first limiting wheel 6 and the second limiting wheel 7. At the same time, the processing mechanism 12 starts to work to punch holes in the elevator guide rail 2, which solves the problem of low processing efficiency in the current punching process of the elevator guide rail bracket, which is usually performed by using a punch press to punch multiple holes one by one.

[0024] Combined with Figure 1-2 As shown, the tightening mechanism 11 includes a rotating rod 1101 fixed on the base 1, a rotating plate 1102 is rotatably installed on the top of the rotating rod 1101, a push wheel 1103 is rotatably installed on one end of the rotating plate 1102, a locking unit 1104 is provided on the other end of the rotating plate 1102, a card slot is opened on the outer circumferential surface of the push wheel 1103, and the mounting plate 9 is embedded in the card slot.

[0025] It should be noted that the counterclockwise rotation of the rotating plate 1102 drives the push wheel 1103 to rotate counterclockwise until the surface of the push wheel 1103 is in close contact with the surface of the mounting plate 9. At this time, the rotating plate 1102 continues to rotate counterclockwise, driving the push wheel 1103 to continue to rotate counterclockwise. The counterclockwise rotation of the push wheel 1103 drives the mounting plate 9 to slide to the left. The sliding of the mounting plate 9 to the left drives the second limiting wheel 7 to slide to the left until the first limiting wheel 6 and the second limiting wheel 7 clamp the elevator guide rail 2.

[0026] Combined with Figure 2As shown, the locking unit 1104 includes a pair of sliding rods 1105 vertically fixed on the rotating plate 1102, a lifting plate 1106 is sleeved on the sliding rods 1105, a locking rod 1107 is fixed to the lower surface of the lifting plate 1106, the locking rod 1107 passes through the rotating plate 1102, an arc block 1108 is fixed on the base 1 and below the locking rod 1107, a plurality of ratchets 1109 are fixed on the arc block 1108, a locking claw 1110 is fixed to the bottom end of the locking rod 1107, and the locking claw 1110 is clamped on the ratchet 1109.

[0028] Combined with Figure 2 As shown, a baffle 1111 is fixed to the top of the sliding rod 1105, a first return spring 1112 is sleeved on the sliding rod 1105 and located between the baffle 1111 and the lifting plate 1106, one end of the first return spring 1112 is fixedly connected to the surface of the baffle 1111, and the other end of the first return spring 1112 is fixedly connected to the surface of the lifting plate 1106, a first fixed rod 1113 is fixed on the rotating plate 1102 and at one end of the locking unit 1104, a second fixed rod 1114 is fixed on the base 1, a second return spring 1115 is arranged between the first fixed rod 1113 and the second fixed rod 1114, one end of the second return spring 1115 is fixedly connected to the first fixed rod 1113, and the other end of the second return spring 1115 is fixedly connected to the second fixed rod 1114.

[0029] It should be noted that when unlocking is required, the lifting plate 1106 is pushed upward, and the lifting plate 1106 moves upward, driving the locking rod 1107 to move upward. The upward movement of the locking rod 1107 can disengage the locking claw 1110 from the ratchet 1109 to complete the unlocking.

At this time, the distance between the first limiting wheel 6 and the second limiting wheel 7 can be readjusted according to the size of the elevator guide rail 2.

[0030] Combined with Figure 1 As shown, the processing mechanism 12 includes a slide plate 1201 slidably mounted on the top of the gantry 3, an electric push rod 1202 is vertically fixed on the slide plate 1201, a hole turner 1203 is fixed to the output shaft end of the electric push rod 1202, one end of the slide plate 1201 is horizontally threadedly connected to a screw rod 1204, the screw rod 1204 is rotatably mounted on the gantry 3, a motor 1205 is fixed to one end of the gantry 3, and the output shaft end of the motor 1205 is fixedly connected to the screw rod 1204.

[0032] The rotating plate 1102 rotates counterclockwise to drive the push wheel 1103 to rotate counterclockwise until the surface of the push wheel 1103 is in close contact with the surface of the mounting plate 9. At this time, the rotating plate 1102 continues to rotate counterclockwise to drive the push wheel 1103 to continue to rotate counterclockwise. The push wheel 1103 rotates counterclockwise to drive the mounting plate 9 to slide to the left. The sliding of the mounting plate 9 to the left drives the second limiting wheel 7 to slide to the left until the first limiting wheel 6 and the second limiting wheel 7 clamp the elevator guide rail 2.

[0033] The locking claw 1110 is clamped on the ratchet 1109. At this time, the locking rod 1107 can only rotate counterclockwise, not clockwise, that is, the rotating plate 1102 can only rotate counterclockwise, not clockwise;

The locking rod 1107 moves upward to disengage the locking claw 1110 from the ratchet 1109 to complete the unlocking. At this time, due to the spring force of the second reset spring 1115, the rotating plate 1102 is driven to rotate clockwise, so that the second limiting wheel 7 no longer presses the mounting plate 9, so that the first limiting wheel 6 and the second limiting wheel 7 no longer clamp the elevator guide rail 2. At this time, the distance between the first limiting wheel 6 and the second limiting wheel 7 can be readjusted according to the size of the elevator guide rail 2.
