Description

  The present invention relates to a heavy vehicle such as a bogie frame of a railway vehicle that is suspended between a transport device that travels on a ceiling track while being suspended in a vertical state and a traveling cart unit that is transported in a horizontal state and travels on a floor track. It is related with the trolley | bogie apparatus for conveyance which can deliver so that it may be safe and not damaged on operation | work.

  Conventionally, in a painting line for a bogie frame of a railway vehicle, since the bogie frame is a heavy object having a weight of about 2 t, it is placed on a floor surface in a horizontal state and is conveyed as it is by an overhead traveling crane or a forklift, The current situation is that the grid blasting process, the painting process, the drying process, and the forced cooling process are performed in this order in the horizontal state.

  Since the carriage frame is placed and transported in a horizontal state, the grid blasting and painting processes must be performed from the top and bottom, and in some cases, reversing work is required. It was.

  Therefore, there is a demand to perform a series of processes by a method in which work can be performed from both sides of the bogie frame while carrying the bogie frame in a vertical state while being conveyed by the carrying device. On the other hand, since the bogie frame is heavy, the bogie frame is placed in a horizontal state from the state where the operator manually suspends the bogie frame vertically to the transfer device on the ceiling side to the running bogie part on the floor side. It is difficult to deliver to.

By the way, a rotating jig used for carrying in and attaching a riser unit obtained by unitizing various pipes such as water supply and distribution pipes necessary for a building such as a building to a predetermined position of the building is known (for example, Patent Document 1). reference).
JP-A-6-288076 (paragraphs 0008, 0026 to 0029 and FIGS. 6 to 9)

  The rotating jig described in Patent Document 1 is used to lift a lightweight object (riser unit) having relatively low rigidity without being deformed, and such a rotating jig is attached to a heavy object such as a carriage frame. When it is lifted or hung, it cannot be applied as it is.

  The present invention provides a work-safety when transferring a workpiece, which is a heavy object such as a carriage frame, from a state in which the workpiece is suspended in a vertical state to a horizontal state or in the opposite process from the horizontal state to the vertical state. It is an object of the present invention to provide a transport cart apparatus capable of delivering a workpiece so as not to be damaged.

  According to the invention of claim 1, a work, which is a heavy object, is transported in a state suspended from a transport device that travels on a ceiling track, and between a transport carriage that travels on a floor track corresponding to the ceiling track. The transfer carriage device that transfers the workpiece by suspending the workpiece, and the transfer carriage is placed on the traveling carriage unit so that the inclination angle in the same direction as the direction of the floor track is variable. A tilting frame is provided, and when the transport carriage receives the workpiece, the tilting angle is gradually increased from a state where the workpiece mounting tilting frame is tilted at a high angle while maintaining the suspended position of the workpiece. While making it shallow and making it horizontal, the said traveling trolley | bogie part is moved to the said floor surface track | orbit direction, It is characterized by the above-mentioned.

  In this way, when receiving a workpiece that is a heavy article suspended in a vertical state on a transport device that travels on a ceiling track, the workpiece placement tilting frame is raised at a high angle, and the workpiece placement tilting is performed. Since the traveling carriage unit that supports the frame is moved in accordance with the shallowness of the workpiece placement tilting frame, the workpiece can be received while the suspension position of the workpiece is maintained. Therefore, even if the work is heavy, the work placement tilting frame can be along the work, and the work can be received without difficulty from the transfer device on the ceiling side.

  Furthermore, supporting and lifting a heavy work in a tilted state placed at a high angle provides better support stability of the work than when lifting and supporting a vertical work. Even in the event of an unforeseen situation where some force is applied, there is an advantage of high safety.

First, since the workpiece is loaded on the workpiece placement tilting frame in a high-angle tilt posture, the vertical component of the workpiece weight is different from the case where the workpiece is placed on the workpiece placement tilting frame in a vertical posture. Since it works with respect to the mounting tilt frame, there is an advantage that it is possible to reduce the possibility that the work, which is a heavy object, falls or the position of the work moves in the lateral direction. here,
Component force in the vertical direction with respect to the work placement tilting frame surface = work weight x COSα
It is. Α is an angle with respect to the horizontal plane with respect to the workpiece placement tilting frame.

Secondly, since the work is loaded on the work placement tilting frame in a high-angle tilting posture, the force to move it horizontally from the hung position even if hung as it is is the lower end of the work The second advantage is that there is little movement of damaging the workpiece by generating a frictional force at the lower end of the workpiece and dragging the workpiece. This force has the same absolute value as the component force perpendicular to the workpiece placement tilting frame surface. The force generated at the lower end of the work becomes smaller as the work is held at a higher angle. here,
Friction force on workpiece mounting tilt frame = workpiece weight × COSα × friction coefficient. The friction coefficient is a friction coefficient between the workpiece placement tilting frame and the workpiece.

  The smaller the angle with respect to the horizontal plane, the greater the force required to stabilize the workpiece against the workpiece placement tilting frame, but conversely, the frictional force generated near the lower end of the workpiece also increases, resulting in damage to the workpiece. Therefore, it is necessary to select a well-balanced angle according to the shape and center of gravity of the workpiece.

  According to a second aspect of the present invention, the conveyance carriage gradually increases the inclination angle of the workpiece mounting tilt frame so that the workpiece is moved from the horizontal state to the high-angle inclination state. It is desirable that the carriage is lifted from the work placement tilting frame of the carriage.

  According to this configuration, when the transfer device is lifted, the work that is a heavy object is transferred from the transfer carriage on the floor side to the ceiling side by performing the operation opposite to that in the case of claim 1. Can be handed over to the device without difficulty.

  According to a third aspect of the present invention, a horizontal movable frame that is movable in the same direction as the direction of the floor track is interposed between the traveling carriage unit and the workpiece placement tilting frame. The work placement tilting frame is provided so as to be tiltable via a rotation shaft portion, and the rotation shaft portion is positioned at an end portion of the traveling carriage portion in a horizontal state of the work placement tilting frame, In the tilted state of the tilting frame, it can be positioned near the center position of the traveling carriage unit.

  In this way, by interposing the horizontal movable frame between the traveling carriage unit and the workpiece placement tilting frame, the traveling carriage unit can be reduced in size and the entire apparatus can be reduced in size. In particular, when the workpiece mounting tilt frame is tilted at a high angle, moving the rotating shaft portion closer to the center position of the traveling carriage unit allows the workpiece, which is a heavy object, to be installed on the traveling carriage unit. Since the center of gravity of the vehicle is moved closer to the center position of the traveling carriage unit, the overall balance is achieved, so that the overall length of the traveling carriage unit can be shortened.

  According to a fourth aspect of the present invention, a traveling device that travels the traveling carriage unit, and a horizontal movable frame that is provided on the traveling carriage unit so as to be movable along the track direction are provided with respect to the traveling carriage unit. It is preferable that the first drive means for moving in the trajectory direction and the second drive means for raising and lowering the workpiece mounting tilt frame.

  With such a configuration, the traveling carriage unit travels by the traveling device, and the first and second driving units perform operations that require the horizontal movable frame and the workpiece placement tilting frame.

  The traveling device according to claim 5, wherein the traveling device is a device that rotationally drives a wheel of the traveling cart unit on the floor track, and the first driving means includes the traveling cart unit and the horizontal movable unit. A guide rail provided in any one of the frames and extending in the track direction, a slider provided on the other of the traveling carriage unit and the horizontal movable frame and slidably engaged with the guide rail, and the traveling carriage unit; A first hydraulic cylinder provided between the horizontal movable frame, and the second driving means includes a fixed link member provided on the horizontal movable frame, and the fixed link member and workpiece mounting A second hydraulic cylinder provided between the tilting frame and the tilting frame can be provided.

  In this case, the traveling carriage unit travels on the floor track by the rotation of the wheels by the traveling device, and the first hydraulic cylinder is actuated so that the slider and the guide rail are engaged with each other. The movable frame moves in the same direction as the floor surface trajectory direction. In addition, the workpiece mounting tilting frame performs a raising / lowering operation with respect to the horizontal movable frame by the operation of the second hydraulic cylinder.

  In this case, as described in claim 6, one end portion of the workpiece placement tilting frame is rotatably connected to the horizontal movable frame, so that the workpiece placement tilting frame is placed on the horizontal movable frame. The fixed link member includes a vertical portion extending downward near the rotation support portion of the horizontal movable frame, and a horizontal portion connected to a lower end of the vertical portion and extending in a direction perpendicular to the vertical portion. And the second hydraulic cylinder is provided between the horizontal portion and the workpiece placement tilting frame.

  According to a seventh aspect of the present invention, a substantially L-shaped pedestal in side view is provided on the workpiece placement tilting frame, and a surface material having elasticity with a low friction coefficient is attached to the pedestal. A guide rail that extends in a direction perpendicular to the direction of the floor track, and a horizontal cradle and a stopper member that is attached to the surface and supports an end portion of the workpiece in an inclined state at a high angle. It is desirable that the structure be movable in accordance with the shape of the workpiece.

  In this way, the workpiece can be stably supported by adjusting the position of the substantially L-shaped pedestal in side view by the horizontal cradle and the stopper member, regardless of which of a plurality of types of work is placed. In addition, even if the workpiece and the horizontal cradle are subjected to friction when the workpiece is suspended and lifted, there is little risk of damage to the workpiece, and the entire surface of the cradle is supported by elastic contact. Damage to the workpiece due to direct contact with the workpiece mounting tilting frame is avoided.

  As described in claim 8, when delivering the workpiece, the angle adjustment of the workpiece placement tilting frame, the horizontal movement of the horizontal movable frame, and the traveling of the traveling carriage unit are interlocked, It is desirable to provide a control device that controls to transfer the workpiece while maintaining the position of the workpiece in the floor surface trajectory direction.

  In this way, the control device maintains (fixes) the position of the workpiece in the floor track direction by adjusting the angle of the workpiece placement tilting frame, horizontally moving the horizontal movable frame, and traveling the traveling carriage unit. Since it is controlled, the operator can concentrate on the lifting and hanging of the workpiece, and the work load can be minimized.

  Since the present invention is configured as described above, the present invention sets the suspension position of the workpiece when the conveyance carriage traveling on the floor track receives the workpiece from the conveyance device that conveys the workpiece in a suspended state. While maintaining the workpiece mounting tilt frame at a high angle, the tilt angle is gradually reduced to a horizontal state, and the traveling carriage unit is moved in the floor track direction. Therefore, even if the workpiece is heavy, the workpiece placement tilting frame can be aligned with the workpiece, and the workpiece can be delivered without difficulty.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a view showing an example of a painting line for a bogie frame of a railway vehicle using a carrying bogie according to the present invention.

  As shown in FIG. 1, a bogie frame processing line 101 of a railway vehicle is transported in a state in which a bogie frame W (workpiece) is suspended by a plurality of traveling cranes 102 (conveyance devices) that move along a ceiling track. The grid blasting process, the painting process, the drying process, and the forced cooling process are sequentially performed. The first station S1 for suspending the carriage frame W to be transported by the traveling crane 102 to the predetermined position of the line 101, and the traveling frame for moving the carriage frame W to detect flaws such as welding. A second station S2 for removing from 102 and suspending again after completion of the flaw detection, and a third station S3 for removing the carriage frame W from the traveling crane 102 for transport to the next machining step, At each of these stations, a predetermined operation is performed using the transport carriage 1. In each station S <b> 1 to S <b> 3, floor tracks 111, 112, 113 for moving the carriage 1 extend in a direction perpendicular to the direction in which the processing line 101 extends corresponding to the ceiling track. In addition, on both sides of the track 112, work places 114 for performing flaw detection such as defects such as welding are provided.

  Between the first station S1 and the second station S2, a grid blast zone Z1 in which grid blast processing is performed is arranged. The processing line after the second station is formed in a loop shape, and the coating zone Z2, the drying zone Z3, and the forced cooling zone Z4 are arranged in this order, and thereafter becomes the third station S3.

  As shown in FIGS. 2 to 4, the transport carriage 1 is provided with a traveling carriage section 2 that can travel on the tracks 111 to 113 and on the traveling carriage section 2 so as to be movable along the floor track direction. And a work placement tilting frame 5 on which the carriage frame W is placed so as to be able to be raised and lowered. The traveling carriage unit 2 has wheels (drive wheels 34 and driven wheels 35) that roll on rails (floor tracks).

  The traveling carriage unit 2 is provided with a guide rail 2a extending in the floor track direction, and the horizontal movable frame 3 is provided with a slider 3a slidably engaged with the guide rail 2a. Further, a first hydraulic cylinder 4 is provided between the traveling carriage unit 2 and the horizontal movable frame 3. By these, the 1st drive means which moves the horizontal movable frame 3 to the said track direction with respect to the traveling trolley | bogie part 2 is comprised. In other words, the first drive means for moving the horizontal movable frame 3 in the track direction with respect to the traveling carriage unit 1 is disposed between the traveling carriage unit 2 and the horizontal movable frame 3.

  Therefore, the operation of the first hydraulic cylinder 4 causes the horizontal movable frame 3 to move linearly with respect to the traveling carriage unit 1 due to the engagement relationship between the guide rail 2a and the slider 3a.

  Further, one end of the workpiece placement tilting frame 5 is rotatably connected to the shaft portion 8 of the horizontal movable frame 3 so that the workpiece placement tilting frame 5 can be raised and lowered on the horizontal movable frame 3. . The horizontal movable frame 3 is provided with a fixed link member 6, and a second hydraulic cylinder 7 is provided between the fixed link member 6 and the workpiece placement tilting frame 5. Thus, the second driving means for raising and lowering the workpiece placement tilting frame 5 with respect to the horizontal movable frame 3 is configured. That is, the second driving means for moving the workpiece placement tilting frame 5 up and down relative to the horizontal movable frame 3 is disposed between the horizontal movable frame 3 and the workpiece placement tilting frame 5.

  The fixed link member 6 is substantially L-shaped and has a vertical portion 6a extending downward in the vicinity of the one end portion, which is the rotation support portion, of the horizontal movable frame 3, and one end portion connected to the lower end of the vertical portion 6a. And a horizontal portion 6b extending in the horizontal direction orthogonal to 6a. A second hydraulic cylinder 7 is provided between the other end of the horizontal portion 6 b and the workpiece placement tilting frame 5.

  Therefore, the work placement tilting frame 5 is configured to move up and down with respect to the horizontal movable frame 3 by the operation of the second hydraulic cylinder 7, and the work placement tilting frame 5 overlaps the horizontal movable frame 3. The horizontal lying position (see FIG. 4) and the standing position (see FIG. 6) in an inclined state that forms a certain angle (for example, about 70 to 80 degrees) at a high angle with respect to the horizontal movable frame 3 are selected. It can be taken as one.

  Further, on the workpiece placement tilting frame 5, a substantially L-shaped pedestal 14 formed by a stopper member 12 and a horizontal cradle 13 is provided so as to be movable in the left-right direction. A guide rail 11 extending in a direction perpendicular to the direction of the floor track is provided on the horizontal cradle 13 and is inclined at a high angle with respect to the guide rail 11 according to the size of the carriage frame W. In this state, the stopper member 12 that supports the lower end of the carriage frame W is movable. As a result, the carriage frame W can be stably supported by adjusting the position of the stopper member 12 regardless of which of the multiple types of carriage frames W is placed, and the position of the carriage frame W may be shifted. It is prevented from falling.

  In order to avoid damage due to friction that occurs when the carriage frame W is lifted, the horizontal cradle 13 is provided with a wooden (or synthetic resin) surface material having elasticity with a certain low friction coefficient. . An elastic member made of synthetic resin (or wood) having elasticity is also attached to the surface of the stopper member 12. Thus, when the carriage frame W is placed, the damage due to the contact between the metals is avoided.

  Further, the cradle 14 is provided such that its position can be adjusted in the left-right direction with respect to the workpiece placement tilting frame 5 having the frame portions 15A, 15B, 15C extending in the left-right direction. That is, the guide rail 21 is provided on the frame portions 15 </ b> A and 15 </ b> C of the workpiece placement tilting frame 5, and the slider 22 slidably engaged with the guide rail 21 is attached to the cradle 14. Clamping means 23 is provided at each end of the cradle 14, and after adjusting the position in the left-right direction using the engagement relationship between the guide rail 21 and the slider 22, the clamping means 23 is placed at the adjusted position. Thus, the cradle 14 can be fixed. A stopper 24 that restricts the movement of the slider 22 is provided in the vicinity of both ends of the guide rail 21.

  31 and 32 are hydraulic pumps for operating the first and second hydraulic cylinders 4 and 7, respectively, and are driven and controlled by a control panel 33 (control device). The traveling carriage unit 2 includes drive wheels 34 driven by a drive motor 33 and driven wheels 35.

  Next, a case where a bogie frame W that is a workpiece is received from a traveling crane (for example, an overhead track traveling chain block) will be described with reference to FIGS.

  As shown in FIG. 7A, the carriage frame W is in a state of being locked to hooks 102 b and 102 b provided at the lower end of the chain 102 a of the traveling crane 102 by the hanging wire 21.

  First, the operator moves the traveling carriage unit 2 while moving the workpiece placement tilting frame 5 from the lying down state shown in FIGS. 8A and 8C to the standing state shown in FIGS. 8B and 8D. Then, it is moved below the suspended cart frame W. At this time, the horizontal movable frame 3 also moves gradually as the tilt angle of the workpiece mounting tilting frame 5 increases under the control of the control panel 33.

  Then, as shown in FIG. 7B, the carriage frame W is hung down on the workpiece placement tilting frame 5 in an inclined state. At this time, the lower end portion of the carriage frame W is supported from the lower side by the stopper member 12 and the carriage frame W itself is a heavy object, so that it is stable without causing misalignment on the workpiece placement tilting frame 5. It will be in the support state. In particular, since the carriage frame W is loaded on the workpiece placement tilting frame 5 in a high-angle tilt posture, the weight of the carriage frame W is different from the case where the carriage frame W is placed on the workpiece placement tilt frame 5 in a vertical posture. Since the vertical component force of the workpiece acts on the workpiece mounting tilting frame 5, the possibility that the bogie frame W that is a heavy object falls or the position of the bogie frame W moves laterally is reduced. Can do.

  Subsequently, the second hydraulic cylinder 7 is operated to gradually reduce the inclination of the workpiece placement tilting frame 5 as shown in FIG. 7C. As the inclination is gradually reduced, the hook 102b is lowered through the chain 102a. Further, the first hydraulic cylinder 4 is actuated to move the horizontal movable frame 3 in the left direction, and the cart itself travels in the left direction.

  By doing so, as shown in FIGS. 7A to 7C, the vertical line of the chain 102a of the traveling crane 102 remains in the same position (that is, in the horizontal direction at the position hung on the hook 102b). The cart frame W can be stably hung on the cart 1 to be in a horizontal state without being shocked safely. An operator travels the cart 1 and transports the cart frame W placed in a horizontal state to a predetermined position.

  Therefore, it is possible to prevent the cart frame W from falling over and preventing the cart frame W from being dragged by the traveling crane 102 (chain 102a) by preventing an excessive force from acting on the cart frame W. In particular, the control panel 33 maintains (fixes) the position of the carriage frame W in the direction of the floor surface track by adjusting the angle of the workpiece placement tilting frame 5, horizontally moving the horizontal movable frame 3, and running the running carriage unit 2. Therefore, the operator can concentrate on the lifting and hanging of the workpiece, and the work load can be minimized.

  In the embodiment described above, the guide rail 2a is provided on the traveling carriage unit 2 and the slider 3a is provided on the horizontal movable frame 3, but conversely, the guide rail is provided on the movable frame, and the slider is provided on the traveling carriage unit. Is possible.

  Moreover, even if it is a case where it is not a trolley | bogie frame as a workpiece | work, when it is a heavy article, the trolley | bogie apparatus for conveyance which concerns on this invention is applicable.
