FR2790989A1 - Trolley for handling parts such as frames and portals during their manufacture comprises columns with pivoting arms - Google Patents

Abstract

The handling device comprises two identical trolleys (18,19) fitted with a frame (1) on which a central column (2) is fixed. The column is fitted with a central arm (3) able to rise or descend on the column.. A rotating plate (4) and a vice (5) are supported by the rotating plate. Each trolley is supported on brake castors (13). To avoid unbalancing of the trolleys a counter weight (17) is placed behind them on the frame. The handling device comprises two identical trolleys (18,19) which are placed opposite each other during use. Each trolley comprises a frame (1) on which a central column (2) is fixed. The column is fitted with a central arm (3) able to rise or descend on the column and be locked by an indexing peg (7). A rotating plate (4) is fixed at the end of the arm and is stopped from rotating by an indexing peg (6). A vice (5) is supported by the rotating plate. On either side the central column are fixed two identical columns. Each of these receives a pivoting arm which slides on the column. The height of this arm is defined by a collar and the arms and the collar are locked by clamping handles. An adjustable stop on the top of each arm enables placing bars (15) and crosspieces (16). Each trolley is supported on brake castors (13). To avoid unbalancing of the trolleys a counter weight (17) is placed behind them on the frame. An Independent claim is also included for the trolley.

Description

The present invention relates to a device for handling parts

  during their manufacture. Traditionally, these assemblies are designed on trestles and require constant effort for the user and often the need for an additional person.

or hoist.

  Also the device according to the invention allows a single person to carry out, and to handle without effort all of the assemblies such as: frames, gates, tubular frames etc., of a very high and bulky weight, and above all to improve the conditions of

  work for the user and to design the execution of the parts to be produced more quickly.

  The invention will be better understood by referring to the drawings.

  Figure 1 shows an overview of the device.

  FIG. 2 represents the front view of one of the carriages constituting the device.

  FIG. 3 represents the side view of one of the carriages constituting the device.

  Figure 4 shows the top view of one of the carriages constituting the device.

  With reference to these drawings, the device comprises two identical carriages (18) -

  (19), placed opposite during use.

  Each carriage (18) - (19) consists of a frame (1) on which is fixed a central column (2) equipped with a central arm (3) which can go up or down on the column

  central (2) and can be locked by an indexing finger (7).

  At the end of the arm (3) is fixed a turntable (4) on an axis (14) whose stop

  in rotation is obtained by the indexing finger (6).

  In addition, a vice (5) is supported by the turntable (4).

  In addition, on the frame 1, on either side of the central column (2) are fixed two identical columns (8). Each column (8) receives a pivoting arm (10) sliding on the

  said column (8), and whose height positioning is defined by a ring (9).

  The blockages of the arms (10) and of the ring (9) are obtained by tightening handles (12). An adjustable stop (11) is mounted at the top of each arm (10) to

  allow the leveling of the bars (15) and crosspieces (16), supported by the device.

  Each carriage (18) - (19) is supported by brake rollers (13) allowing the

  movement of the carriages (18) - (19).

  To avoid the imbalance of the carriages (18) - (19), a counterweight (17) is placed at

  the rear of the carriages (18) - (19) on the frame (1).

  As an indication, the manufacturing of a frame is carried out by installing the first bar

  to be welded (15) and clamped horizontally in the vice (5) of the carriage (18).

  The same operation is carried out in the vice (5) of the second carriage (19).

  The clamps (5) are at the same level thanks to the height adjustment of the central arm (3) on

the central column (2).

  Before presenting the crosspieces (16) which will form the frame, the user will place the stops (11) under the bars (15) taken in the vices (5) to ensure good geometry of the bars (15) and crosspieces (16 ) and the weight efforts will be recovered by the stops (11). The bars (15) and the crosspieces (16) will be welded on one side. To pass on the other face, the user will rotate the assembly of bars (15) and crosspieces (16) which forms the frame around the axis (14) after removing the indexing finger (6 ) of the turntable (4). The user will choose the angle desired to complete the frame, since the plate

  turning (4) can be locked in different positions thanks to the indexing finger (6).

  The part to be produced is therefore handled with great ease by the user.
