Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide rails, in particular to an automatic feeding device for elevator guide rails. Background Art

[0002] Elevator guide rails are the safety rails for elevators to travel up and down in the hoistway. The guide rails are installed on the hoistway wall and are fixedly connected to the hoistway wall by guide rail brackets and guide rail supports. The commonly used guide rails for elevators are "T"-shaped guide rails, which have the characteristics of strong rigidity, high reliability, safety and low cost. The surface of the guide rail must be smooth without obvious unevenness. Since the guide rail is the shuttle rail for the guide shoes and safety tongs on the elevator car, the clearance must be ensured during installation. During the production and processing of elevator guide rails, it is necessary to drill holes in the elevator guide rails to facilitate the connection between the guide rails. During the drilling process, continuous feeding and discharging are required. The current feeding and discharging operations are all carried out manually, resulting in low work efficiency. To solve the above problems, we propose an automatic feeding device for elevator guide rails. Summary of the Invention

An automatic feeding mechanism is arranged between the two transportation mechanisms. A punching machine is arranged above the automatic feeding mechanism. The automatic feeding mechanism includes a U-shaped support fixed on the base.

[0008] As a preferred technical solution, the limiting mechanism includes a pull rod arranged below the C-shaped support, and limiting units are arranged at both ends of the pull rod. The limiting unit includes a mounting frame fixed on the lower surface of the C-shaped support, and a limiting block is vertically slidably arranged inside the mounting frame. The limiting block vertically penetrates the C-shaped support, and a first inclined surface is formed on the top of the limiting block at one end that is tilted upward toward the clamping plate. A second sliding rod is vertically inserted and sleeved inside the mounting frame and located below the limiting block. The top of the second sliding rod is fixedly connected to the lower surface of the limiting block, and a stop block is fixed at the bottom end of the second sliding rod.

[0012] (III) Beneficial effects

[0013] The beneficial effects of the utility model are:

[0014] (1) During operation, the T-type elevator guide rail is placed on a transport mechanism, which transports the T-type elevator guide rail to the automatic feeding mechanism. The rollers and guide wheels cooperate with the clamping mechanism and the limit mechanism to limit and fix the T-type elevator guide rail. At this time, the puncher starts to punch holes in the T-type elevator guide rail. After the holes are punched, the limit mechanism is reset, and the guide wheel drives the T-type elevator guide rail to move to the right. Finally, the T-type elevator guide rail after the holes are punched is transported to another transport mechanism. The fully automatic loading and unloading solves the problem of continuous loading and unloading during the drilling process. The current loading and unloading operations are all performed manually, which has low work efficiency.

[0015] (2) When the T-shaped elevator guide rail is input from the upwardly tilted end of the clamping plate, the pressure roller cooperates with the first slide bar and the first return spring to slowly clamp the T-shaped elevator guide rail.

[0016] (3) The T-shaped elevator guide rail is input from the end that warps upward from the pressing plate. The top of the limit block is formed with a first inclined surface. At this time, the T-shaped elevator guide rail presses the limit block downward into the U-shaped support. At this time, the T-shaped elevator guide rail continues to be transported to the right until the other end of the T-shaped elevator guide rail abuts against another limit block. At this time, under the action of the spring force of the second return spring, the limit block with the first inclined surface formed on the top is driven to move upward. The cooperation of the two limit blocks makes the T-shaped elevator guide rail unable to move forward and backward. At the same time, the T-shaped elevator guide rail is fixed in cooperation with the supporting roller, the guiding wheel, and the pressing plate.

[0017] (4) The output shaft of the air cylinder moves to the right, driving the pull rod to move to the right. The pull rod moving to the right drives the clamping block to move to the right. The bottom of the clamping groove is formed with a second inclined surface, and the bottom of the clamping block is formed with a third inclined surface. The second inclined surface and the third inclined surface abut against each other. The clamping block moving to the right drives the clamping groove to move downward, that is, drives the limit block to move downward. The limit block moving downward can unlock the T-shaped elevator guide rail. At this time, the motor starts, driving the guiding wheel to rotate, so as to drive the T-shaped elevator guide rail to move to the right onto the transport mechanism. Description of the Drawings

[0023] A further description of an automatic feeding device for elevator guide rails of the present invention will be made in conjunction with the drawings.

[0024] Combined with the attached Figure 1-3 As shown in the figure, an automatic feeding device for elevator guide rails includes a base 1 and a T-shaped elevator guide rail. A pair of transportation mechanisms 2 are arranged on the base 1. An automatic feeding mechanism 3 is arranged between the two transportation mechanisms 2. A punching machine 4 is arranged above the automatic feeding mechanism 3. The automatic feeding mechanism 3 includes a U-shaped support 5 fixed on the base 1. A number of rollers 6 are sequentially installed on the U-shaped support 5 along the length direction of the U-shaped support 5. Guide wheels 7 are installed on both sides of the rollers 6 on the U-shaped support 5. A pressing mechanism 8 for pressing the T-shaped elevator guide rail is arranged above the U-shaped support 5. A limiting mechanism 24 for pressing against the T-shaped elevator guide rail is arranged below the U-shaped support 5.

[0025] It should be noted that during operation, the T-shaped elevator guide rail is placed on one transportation mechanism 2. The transportation mechanism 2 transports the T-shaped elevator guide rail to the automatic feeding mechanism 3. The rollers 6 and the guide wheels 7 cooperate with the pressing mechanism 8 and the limiting mechanism 24 to limit and fix the T-shaped elevator guide rail. At this time, the punching machine 4 starts to punch the T-shaped elevator guide rail. After punching, the limiting mechanism 24 resets, and the guide wheel 7 drives the T-shaped elevator guide rail to move to the right. Finally, the punched T-shaped elevator guide rail is transported to another transportation mechanism 2, achieving full-automatic feeding and discharging, and solving the problem of low work efficiency caused by the need for continuous feeding and discharging during the hole-opening process, where the current feeding and discharging operations are all manual.

[0026] Combined with the attached Figure 2 As shown in the figure, the pressing mechanism 8 includes a gantry 9 fixed on the U-shaped support 5. A mounting plate is fixed on the gantry 9. A pair of first sliding rods 10 are vertically inserted into the mounting plate. A baffle 11 is fixed at the top of the first sliding rods 10. A pressing plate 12 is fixed at the bottom of the first sliding rods 10. A number of pressure rollers 25 are installed on the pressing plate 12 along the length direction of the pressing plate 12. A first return spring 13 is sleeved on the first sliding rods 10 between the mounting plate and the pressing plate 12. One end of the pressing plate 12 is upturned.

[0027] It should be noted that when the T-shaped elevator guide rail is input from the upturned end of the pressing plate 12, the pressure rollers 25 cooperate with the first sliding rods 10 and the first return spring 13 to slowly press the T-shaped elevator guide rail.

[0028] Combined with the attached Figure 2-3As shown, the limiting mechanism 24 includes a pull rod 14 arranged below the C-shaped support 5, and limiting units are arranged at both ends of the pull rod 14. The limiting unit includes a mounting frame 15 fixed on the lower surface of the C-shaped support 5, and a limiting block 16 is vertically slidably arranged inside the mounting frame 15. The limiting block 16 vertically penetrates the C-shaped support 5, and the top of the limiting block 16 at the end that is upwardly tilted toward the clamping plate 12 is formed with a first inclined surface, and a second sliding rod 17 is vertically inserted and sleeved inside the mounting frame 15 and below the limiting block 16. The top of the second sliding rod 17 is fixedly connected to the lower surface of the limiting block 16, and a stopper 18 is fixed at the bottom end of the second sliding rod 17. A second return spring 19 is sleeved on the second sliding rod 17 and located between the limiting block 16 and the mounting frame 15. A slot 20 is opened on one side wall of the limiting block 16, and blocks 21 are fixed at both ends of the C-shaped support 5. The block 21 can be embedded in the slot 20.

[0029] It should be noted that the T-type elevator guide rail is input from the upwardly tilted end of the clamping plate 12, and a first inclined surface is formed on the top of the limit block 16. At this time, the T-type elevator guide rail presses the limit block 16 downward into the U-shaped support 5. At this time, the T-type elevator guide rail continues to be transported to the right until the other end of the T-type elevator guide rail abuts against another limit block 16. At this time, due to the spring force of the second return spring 19, the limit block 16 with the first inclined surface formed on the top is driven to move upward. The two limit blocks 16 cooperate to prevent the T-type elevator guide rail from moving forward and backward, and at the same time cooperate with the roller 6, guide wheel 7, and clamping plate 12 to fix the T-type elevator guide rail.

[0030] Combined with Figure 3 As shown, a second inclined surface is formed at the bottom of the slot 20, and a third inclined surface is formed at the bottom of the block 21, and the second inclined surface and the third inclined surface abut against each other.

[0031] Combined with Figure 3 As shown, a motor 22 and a cylinder 23 are fixed to the lower surface of the U-shaped support 5 , the output shaft of the motor 22 is fixedly connected to the rotating shaft of one of the guide wheels 7 , and the output shaft of the cylinder 23 is fixedly connected to one end of the pull rod 14 .

[0032] It should be noted that the rightward movement of the output shaft of the cylinder 23 drives the pull rod 14 to move to the right, and the rightward movement of the pull rod 14 drives the block 21 to move to the right. The bottom of the slot 20 is formed with a second inclined surface, and the bottom of the block 21 is formed with a third inclined surface. The second inclined surface and the third inclined surface abut against each other. The rightward movement of the block 21 drives the slot 20 to move downward, that is, drives the limit block 16 to move downward. The downward movement of the limit block 16 can unlock the T-type elevator guide rail. At this time, the motor 22 starts and drives the guide wheel 7 to rotate, thereby driving the T-type elevator guide rail to move to the right to the transport mechanism 2.

[0033] Combined with Figure 1As shown, the transport mechanism 2 includes a frame, with active rollers installed at both ends of the frame, and a belt is sleeved on the outer circumference of the active roller.

[0034] Working principle: When working, the T-type elevator guide rail is placed on a transport mechanism 2, and the transport mechanism 2 transports the T-type elevator guide rail to the automatic feeding mechanism 3. The rollers 6 and guide wheels 7 cooperate with the clamping mechanism 8 and the limit mechanism 24 to limit and fix the T-type elevator guide rail. At this time, the puncher 4 starts to punch holes in the T-type elevator guide rail. After punching, the limit mechanism 24 is reset, and the guide wheel 7 drives the T-type elevator guide rail to move to the right. Finally, the T-type elevator guide rail after the hole is punched is transported to another transport mechanism 2. Fully automatic loading and unloading solves the problem of continuous loading and unloading during the hole drilling process. The current loading and unloading operations are all performed manually, and the work efficiency is low.

Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary personnel in this field should fall within the protection scope of the present invention.
