DETAILED DESCRIPTION

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-4As shown, an elevator door panel clamping device includes a base 3, a column 4 is arranged on the base 3, a groove is opened at the upper end of the column 4, a first motor 5 is arranged inside the groove, a sleeve 6 is rotatably connected to the upper end of the column 4, the output end of the first motor 5 is fixedly connected to the inner top surface of the sleeve 6, an extension plate 7 and a counterweight 8 are arranged on the outer surface of the sleeve 6, the extension plate 7 and the counterweight 8 are connected to the sleeve 6 through a pull rope 9, a top cover 10 is arranged at one end of the extension plate 7, a cylinder 11 is symmetrically arranged on the top cover 10, a ring plate 12 is arranged below the top cover 10, the output end of the cylinder 11 is fixedly connected to the ring plate 12, and the four corners of the lower surface of the ring plate 12 are A screw rod 13 and a guide rod 14 are separately provided, a second motor 15 for driving the screw rod 13 to rotate is provided on the ring plate 12, a threaded tube 16 is threadedly connected to the screw rod 13, a support rod 17 is provided on the outer surface of the threaded tube 16, the guide rod 14 is slidably connected to the support rod 17, a sliding sleeve 18 is provided at one end of the support rod 17, a sliding rod 19 is slidably connected inside the sliding sleeve 18, a support block 20 is provided at one end of the sliding rod 19, a guide block 21 is provided at the other end of the sliding rod 19, a spring 22 is sleeved on the sliding rod 19, the spring 22 is located between the guide block 21 and the sliding sleeve 18, and a guide plate 23 matching the guide block 21 is provided on the ring plate 12.

[0018] The production line includes two roller conveyors 1. The first motor 5 drives the sleeve 6 to rotate, so that the elevator door panel 2 on one roller conveyor 1 can be transferred to the other roller conveyor 1. When the elevator door panel 2 on the previous roller conveyor 1 is clamped, the specific steps are as follows: Figure 1As shown, when the elevator door panel 2 is transported to a predetermined position by the roller conveyor 1, the roller conveyor 1 stops moving, and the position of the elevator door panel 2 does not change at this time. Then the four second motors 15 are controlled to start, and the four second motors 15 respectively control the rotation of the screw rod 13, and through the cooperation with the guide rod 14, the threaded tube 16 can move vertically upward along the screw rod 13. Each screw rod 13 is provided with a plurality of threaded tubes 16. When the four threaded tubes 16 located at the same height move upward at the same time and at the same speed, the support block 20 will be driven to move upward synchronously. The four support blocks 20 hold up the elevator door panel 2 from the bottom of the elevator door panel 2. When the support block 20 continues to move upward, the guide block 21 will contact with the fixed guide plate 23, and the guide plate 23 squeezes the guide block 21, so that the guide block 21 moves in the direction close to the elevator door panel 2, so that extrusion is formed between the support block 20 and the elevator door panel 2, thereby The elevator door panels 2 are squeezed and fixed by four support blocks 20, thereby completing the clamping of one of the elevator door panels 2. When the next elevator door panel 2 needs to be clamped, the previous elevator door panel 2 needs to be moved upward to a certain height to reserve a certain space for the next elevator door panel 2. After the device completes the clamping of multiple elevator door panels 2, the ring plate 12 is driven to move upward by the retraction of the output end of the cylinder 11, thereby driving the elevator door panel 2 on the support block 20 to move upward. When the lower ends of the screw rod 13 and the guide rod 14 are higher than the roller conveyor 1, the output end of the cylinder 11 stops retracting, and then the sleeve 6 is driven to rotate by the first motor 5 to transfer the clamped elevator door panel 2 from the current roller conveyor 1 to another roller conveyor 1, and then the elevator door panel 2 is placed on the roller conveyor 1 in turn by intermittently controlling the threaded tube 16 to move downward, thereby realizing the transfer of the elevator door panel 2.

[0019] When the guide block 21 is separated from the guide plate 23 , the support block 20 can move toward the sliding sleeve 18 under the action of the spring 22 , thereby increasing the distance between the two support blocks 20 that are arranged opposite to each other.

[0020] The counterweight part 8 is used to make the device reach a relatively balanced state, so as to avoid a serious tilt of the device.

[0021] The sliding rod 19 can only move along the sliding sleeve 18 , and no rotation occurs between the sliding rod 19 and the sliding sleeve 18 .

[0022] Furthermore, it also includes a fixing plate 24, on which a limiting groove 25 is provided to cooperate with the screw rod 13 and the guide rod 14, and the lower ends of the screw rod 13 and the guide rod 14 can be inserted into the limiting groove 25. The number of fixing plates 24 is the same as that of the roller conveyor 1, and the fixing plate 24 is used to support the screw rod 13 and the guide rod 14, thereby ensuring the stability of the second motor 15 when driving the screw rod 13 to rotate, and also improving the stability of the guide rod 14.

[0023] Furthermore, anti-deflection rods 26 are symmetrically arranged on the upper surface of the ring plate 12. The anti-deflection rods 26 are slidably connected to the top cover 10. The anti-deflection rods 26 can improve the stability of the ring plate 12 when it moves upward and prevent the ring plate 12 from tilting.

[0024] Furthermore, an anti-drop block 27 is provided at the top end of the anti-deflection rod 26 .

[0025] Furthermore, the support block 20 is made of rubber material. The support block 20 made of rubber material can avoid deformation of the elevator door panel 2 due to excessive clamping force when clamping the elevator door panel 2 through its own deformation, which is beneficial to protecting the elevator door panel 2.

[0026] When the device is in use, it can continuously clamp a plurality of elevator door panels 2, so that when the elevator door panels 2 are transferred, the time wasted due to the process of multiple rotations can be reduced, time can be saved, the efficiency of the transfer can be improved, and the use effect is good.

[0027] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
