Description

Technical Field

[0001] The utility model relates to the technical field of column processing, in particular to an automatic column feeding device. Background Art

[0002] In order to improve road safety, guardrails are generally used for safety protection. The existing technology mostly uses columns to fix the guardrails, uses the deformation of the guardrails to absorb collision energy, and forces out-of-control vehicles to change direction and return to the normal driving direction to prevent the vehicle from running off the road. For this reason, it is necessary to use columns to ensure the installation stability of the guardrails.

[0003] The prior art mostly drills holes in the columns so that the guardrails can be locked and fixed on the columns with bolts. However, current column processing equipment, such as an automatic column loading device disclosed in announcement number CN209777476U, uses a conveyor chain, a driving gear and a driven gear to realize automatic conveying and loading of the columns. However, it only realizes the continuous conveying process of the columns, and the columns need to be punched synchronously during the conveying process. If the columns are punched in a dynamic process, it is very easy to cause the punching position deviation, which affects its correspondence with the punching position of the guardrail, and the locking and fixing between the guardrail and the columns cannot be achieved.

[0008] Preferably, the feeding mechanism includes a driving shaft rotatably installed between the machine body and the load-bearing bracket and fixedly connected to the output end of the driving motor, and a driven shaft is rotatably installed in the load-bearing bracket, a steering rod and a transmission star plate are respectively fixedly installed on the driving shaft and the driven shaft, a traction bolt is integrally connected to the steering rod, and four long holes for slidingly fitting the traction bolt are provided in the transmission star plate, a traction turntable is integrally connected to the driven shaft, a limit clamp is slidably fitted on the load-bearing bracket and movably extends to the limit sleeve, and a traction connecting rod for movably pulling the limit clamp is eccentrically provided on the traction turntable.

[0009] Preferably, the four long holes are equidistantly distributed in the circumferential direction, and the two ends of the traction link are respectively connected to the traction turntable and the limit clamp pin.

[0010] Preferably, the hole-opening mechanism includes a flat turntable fixedly connected to the driving shaft, and a reciprocating rocker arm movably pulled by the flat turntable is rotatably installed at the lower end of the machine body, a guide long groove connected to the material passing hole is opened in the machine body, and a punching part extending into the material passing hole is slidably sleeved in the guide long groove, and a traction rod is connected between the reciprocating rocker arm and the punching part.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

It should be noted that the column is vertically transported by the limiting sleeve 4, so that the column passes through the feeding through hole 3 in a step-by-step motion manner, and a driving motor 5 is fixedly installed on the body 1.

[0021] The machine body 1 is provided with a feeding mechanism for intermittently conveying columns through a load-bearing bracket 2, and the feeding mechanism includes a driving shaft 6 rotatably installed between the machine body 1 and the load-bearing bracket 2 and fixedly connected to the output end of the driving motor 5, and a driven shaft 7 is rotatably installed in the load-bearing bracket 2, and a steering rod 8 and a transmission star plate 9 are respectively fixedly installed on the driving shaft 6 and the driven shaft 7, a traction bolt 10 is integrally connected to the steering rod 8, and four long holes for slidingly fitting the traction bolt 10 are opened in the transmission star plate 9, and a traction turntable 11 is integrally connected to the driven shaft 7, and the traction bolt 10 and the transmission star plate 9 are provided with a movable connection. The movable star plate 9 can convert the continuous rotation of the driving shaft 6 into the step-by-step rotational movement of the driven shaft 7. The sliding sleeve in the load-bearing bracket 2 is provided with a limit clamp 12 that can be movably extended to the limit sleeve 4, and the traction turntable 11 is eccentrically provided with a traction connecting rod 13 for movably traction of the limit clamp 12. The limit clamp 12 can telescopically move between the load-bearing bracket 2 and the limit sleeve 4. In the contracted state, it stops clamping the column so that the column moves vertically downward, and in the extended state, it firmly clamps the column so that the column is fixed in the limit sleeve 4 and the material passing hole 3, which is convenient for opening the hole.

[0022] The machine body 1 is provided with a hole-punching mechanism which is transmission-connected with the feeding mechanism and performs punching processing on the column. The hole-punching mechanism includes a flat turntable 14 fixedly connected to the driving shaft 6, and a reciprocating rocker arm 15 movably pulled by the flat turntable 14 is rotatably installed at the lower end of the machine body 1. A guide slot 16 connected to the feeding through hole 3 is opened in the machine body 1, and a punching member 17 extending to the feeding through hole 3 is slidably sleeved in the guide slot 16. A traction rod 18 is connected between the reciprocating rocker arm 15 and the punching member 17. The punching member 17 realizes telescopic movement in the guide slot 16 and the feeding through hole 3, so as to facilitate the punching operation on the column and facilitate the later installation of bolts for assembly.

[0023] The load-bearing bracket 2 is vertically arranged on one side of the machine body 1 , and the limiting sleeve 4 is located above the material passing through hole 3 .

[0024] The four long holes are equidistantly distributed around the circumference, and the two ends of the traction link 13 are respectively connected to the traction rotating disk 11 and the limit clamp 12 with pins. Figure 3 The traction bolt 10 is sequentially mounted in the four long holes during the rotation process to drive the driven shaft 7 to deflect 90° each time.

Both ends of the traction rod 18 are respectively connected to the reciprocating rocker arm 15 and the punching member 17 by pins, so that the punching member 17 can realize reciprocating extension and retraction to perform punching operation on one side of the column.

[0026] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] Put the long strip column vertically into the limiting sleeve 4 so that the column passes through the material through hole 3 in a straight line;

The driving shaft 6 drives the traction bolt 10 to rotate through the steering rod 8, and the traction bolt 10 set in the long hole of the transmission star plate 9 drives the driven shaft 7 to perform step-by-step rotation. The driven shaft 7 drives the limit clamp 12 to perform linear reciprocating telescopic movement through the traction turntable 11 and the traction connecting rod 13. When the limit clamp 12 contracts, the column can slide in the limit sleeve 4, and vice versa, the column can be limited and fixed in the limit sleeve 4;

[0030] The driving shaft 6 drives the planar turntable 14 to rotate synchronously, and the planar turntable 14 drives the reciprocating swing rod 15 to swing left and right through the traction yoke 1401. The reciprocating swing rod 15 drives the punching member 17 to extend into the material passing hole 3 through the traction rod 18 to perform punching operations on the fixed column.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
