Description

Technical Field

[0001] This utility model relates to the field of bolster side frame production technology, and in particular to a bolster side frame buffer conveying device. Background Technology

[0002] The side frames of bolsters used in rail transit are generally large and heavy. During the transfer operation, they are usually hoisted by lifting equipment, and the workpieces are stacked and stored by dividing the material racks into areas or transported in a centralized manner by freight cars.

[0003] The above operating method has the following problems:

[0004] 1. The use of bridge-type rail trolleys and other lifting equipment to frequently lift between various processes results in extremely low work efficiency, high investment and maintenance costs, high labor costs, and safety risks due to the frequent mixing of lifting machinery and personnel.

[0005] Second, the process layout of storing and placing workpieces and finished products in designated areas using racks and flat stacking methods is chaotic and affects the production continuity between different processes.

[0006] Third, the cost of transporting goods by centralized transfer of freight vehicles is high, and there are certain safety hazards in the operation of vehicles within the factory area.

[0007] Therefore, this application provides a bolster side frame buffer conveying device to meet the requirements. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example: Reference Figure 1 The bolster side frame buffer conveying device shown includes a chain plate conveyor 1, a flexible clamping mechanism 2, and a track gauge adjustment mechanism 3;

[0039] Chain conveyor 1: Two sets are arranged on the left and right sides, and both are installed on the base 1001 to support and transport the side frame 4 and the rocker arm 5;

[0040] The two sets of flexible clamping mechanisms 2 are installed on the chain conveyor 1 to clamp and fix the transport side frame 4 and the rocker arm 5;

[0041] Track gauge adjustment mechanism 3: used to adjust the distance between the two sets of chain conveyors 1 to accommodate different specifications of side frames 4 and bolsters 5.

[0042] In use, the side frame 4 or the bolster 5 can be placed directly on the oppositely arranged flexible clamping mechanism 2 and transported by the chain conveyor 1.

[0043] As a preferred embodiment of this example, Figure 1-6 As shown, the flexible clamping mechanism 2 includes multiple sets of opposing bayonet bases 2002. The bayonet bases 2002 are mounted on the connecting chain plates 2001 of the chain conveyor 1. The bayonet bases 2002 are provided with bolster clamping blocks 2007 and side frame L-shaped clamping blocks 2006 from top to bottom. The bolster clamping blocks 2007 are rotatably connected to the bayonet bases 2002 through a first rotating shaft 2008, and the side frame L-shaped clamping blocks 2006 are rotatably connected to the bayonet bases 2002 through a second rotating shaft 2010.

[0044] The bayonet base 2002 is provided with a first limit stop 2005 and a second limit stop 2009 positioned vertically.

[0045] Each bayonet base 2002 is rotatably mounted with an upper support wheel 2003;

[0046] The bayonet base 2002 has a built-in return spring 2011, and the two ends of the return spring 2011 are respectively connected to the bayonet base 2002 and the side end of the rocker clamping block 2007.

[0047] A lower support wheel 2004 is rotatably mounted on the connecting chain plate 2001, and the lower end of the lower support wheel 2004 is in rolling contact with the chain plate support block 2012 at the upper end of the chain plate conveyor 1.

[0048] The side frame 4 or bolster 5 can be placed directly on this buffer conveyor, and the side frame 4 or bolster 5 can be buffered and transported through this buffer conveyor.

[0049] When placing side frame 4 (e.g.) Figure 5 As shown), the two ends of its side frame 4 are supported on the bottom edges of two sets of oppositely arranged side frame L-shaped clamping blocks 2006, and the upper ends of the oppositely arranged side frame L-shaped clamping blocks 2006 clamp the two ends of the side frame 4.

[0050] When placing the rocking pillow 5 (as shown) Figure 4 As shown), the lower end of the rocker 5 is supported on the bottom edge of two opposing L-shaped clamping blocks 2006. The upper ends of the opposing side frame L-shaped clamping blocks 2006 clamp the two ends of the side frame 4. At the same time, the rocker clamping block 2007 contacts the inclined surfaces on both sides of the rocker 5 to form a support clamp. The two opposing upper support wheels 2003 form a rolling clamp on both sides of the rocker 5. The multiple clamping combinations form a reliable and stable clamp for the rocker 5.

[0051] A lower support wheel 2004 is provided, which rolls in contact with the chain plate support block 2012 to counteract the downward pressure of the side frame 4 or the bolster 5 and prevent the transmission components in the chain plate conveyor 1 from being damaged due to excessive pressure.

[0052] It should be noted that: First, when the bolster 5 placed on the buffer conveyor is hoisted away, the bolster clamping block 2007 automatically returns to its original position due to the elastic force of the return spring 2011; Second, the first limit stop 2005 is welded at the extreme position to prevent the bolster clamping block 2007 from rotating too far and failing to return to its original position, thus affecting the clamping of the next wheel; Third, the center of gravity of the side frame L-shaped clamping block 2006 is always located on the outside of the second rotating shaft 2010 (i.e., the side closer to the upper support wheel 2003), so initially, the side frame L-shaped clamping block 2006... The outer side of 06 contacts the second limit stop 2009. Even if the side frame 4 or bolster 5 is mounted on the L-shaped clamping block 2006, the center of gravity of the L-shaped clamping block 2006 is always located on the outer side of the second rotating shaft 2010. When the side frame 4 or bolster 5 is removed, the L-shaped clamping block 2006 rotates outward around the second rotating shaft 2010 by its own gravity and finally contacts the second limit stop 2009. Fourth, the chain conveyor 1 and the track gauge adjustment mechanism 3 are both electrically connected to the PLC controller.

[0053] As a preferred embodiment of this example, Figure 2As shown, the upper end of the chain plate support block 2012 is provided with a guide rib 2013, and the bottom of the connecting chain plate 2001 is provided with a limiting groove that matches the guide rib 2013.

[0054] The cooperation between the guide rib 2013 and the limiting groove can effectively prevent the connecting chain plate 2001 from moving, which is beneficial to the stability of clamping the workpiece.

[0055] As a preferred embodiment of this example, Figure 4 As shown, the track gauge adjustment mechanism 3 includes an electric telescopic cylinder 3001. The output end of the electric telescopic cylinder 3001 is connected to the movable base 3002. A set of chain conveyors 1 is installed on the movable base 3002, and the movable base 3002 is slidably set on the base 1001.

[0056] The electric telescopic cylinder 3001 can be controlled to move the movable base 3002 as needed, thereby changing the distance between the two chain conveyors 1 to accommodate different specifications of the side frame 4 and bolster 5.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
