Description

  The present invention relates to a load moving carriage that is arranged in a groove of a load carrier floor and moves a load in the load carrier.

  2. Description of the Related Art In recent years, a plurality of grooves extending in the traveling direction of a vehicle are installed on the bed floor of a vehicle such as a truck, and the movement of the load in the bed has been facilitated using a load moving carriage that moves in the groove. As this type of cargo movement cart, a cart body that is placed in the groove so as to have a longitudinal length in the longitudinal direction and the load is placed thereon, rolls on the bottom surface of the groove and moves the cart body to the longitudinal direction. A moving roller that moves in a direction, an elevating mechanism that elevates and lowers the cart body relative to the moving roller, and an elevating mechanism that is detachably inserted into the elevating mechanism at one end in the longitudinal direction of the cargo moving cart. A device including an operation rod to be operated is known (for example, see Patent Document 1).

  For example, when moving a load placed on a pallet (loading platform) in the loading platform in the traveling direction of the vehicle, the loading movement cart is inserted into the grooves arranged below the left end side and the right end side of the pallet, and the lifting mechanism The pallet is placed on the trolley body of each load moving trolley and is lifted from the pallet floor by raising the trolley body with respect to the moving roller by operating the operation bar. In this state, the pair of load moving trolleys are moved in the groove in the traveling direction of the vehicle, thereby moving the load in the load trolley.

JP-A-8-67246

  Each of the load moving carts is provided with the moving roller in order to facilitate the movement of the load. However, the cargo often has a weight exceeding 1 t depending on the type and amount of the load. Furthermore, since the load carriage is located in the groove below the load that is moved by the operator, the load carriage is not always located at the complete center in the groove, Also, the position of the cargo movement carriage in the groove changes depending on the inclination of the cargo bed floor. For example, when the cargo bed floor surface is inclined in the width direction of the vehicle, not only the moving roller of each preceding cargo movement carriage but also the side face of the carriage body comes into contact with the groove. For this reason, there are cases in which the burden on the operator when moving the pallet is not sufficiently reduced only by the moving roller, and it is necessary to further improve the operability of the load moving carriage.

  Further, it is necessary to change the position and direction of the load moving carriage according to the position and moving direction of the moving load. For example, when moving the load on the back side of the loading platform, the operator stands on the loading platform entrance, operates the loading carriage with the operation rod, and moves the loading toward the entrance near the loading platform entrance. In the case of moving, an operator stands on the back side of the loading platform for the safety and operates the loading movement cart with the operation rod, so it is necessary to change the position and direction of the loading movement cart. In addition, after the moving work of the load on the loading platform is completed, the loading moving cart is reversed in the groove so that the moving roller faces upward so that the loading moving cart does not move unnecessarily in the groove when the vehicle moves. In order to prevent the movement of the

  Here, since the pallet exceeding 1 t is placed on the load moving carriage, it is made of a metal material so as to withstand repeated use. For this reason, the load moving cart is never light in performing operations such as lifting, direction change, and movement prevention by an operator, and it is necessary to further improve the operability of the load moving cart.

  This invention is made | formed in view of such a situation, Comprising: It aims at providing the load moving trolley | bogie which can improve the operativity by an operator.

In order to solve the above problems, the present invention employs the following means.
The load moving cart according to the first aspect of the present invention is arranged in the groove of the load bed floor surface so as to have a length in the longitudinal direction of the groove, and has a placement surface on which the load is placed and opens downward. A carriage main body having a hollow portion to be moved, and a plurality of movements that are provided in the hollow portion at intervals in the longitudinal direction and roll on the bottom surface of the groove to move the carriage main body in the longitudinal direction within the groove. A load moving carriage provided with a roller and a lifting mechanism that raises and lowers the carriage main body with respect to the moving roller and arranges the mounting surface above the upper end of the groove when the carriage rises, A housing part that houses an operation mechanism for operating lifting by the lifting mechanism is provided at one end in the longitudinal direction so as to protrude upward from the mounting surface, and the width of the cart body at one longitudinal end side of the cart body On each side of the direction The anti-slip recesses when lifting cargo moving carriage is provided, the recess is to raise the carriage body relative to the moving roller by the lifting mechanism to the ground to the bottom of the groove (1) Symbol mobile roller When the load moving carriage is disposed in the groove so that the moving roller is above, at least a part is disposed above the upper end of the groove. all SANYO being, or, (2) the moving roller provided below the mounting surface in a state of being grounded to the bottom surface of said groove, said cargo moving carriage such that the moving roller is at the top When disposed in the groove, Ru der least in part is disposed above the upper end of the groove.

According to this aspect, when the load moving carriage is arranged in the groove so that the moving roller is on the upper side, or when the load moving carriage arranged in the groove is lifted, the load moving carriage by the operator is used. The operability can be improved.

In the above aspect, a pair of rolling elements provided on one side and the other side in the width direction of the carriage main body and supported so as to be rotatable around an axis along the height direction of the carriage main body are provided. It is preferable that a part of the outer peripheral surface of the moving body protrudes from one side surface or the other side surface of the cart body in the width direction.
In this case, since the rolling element is supported by the carriage main body, the rolling element is lifted with respect to the moving roller by the lifting mechanism, and the rolling element is positioned at a higher position on the inner surface of the groove in the load conveyance state. It is possible to more reliably prevent the bogie body from falling over in the groove while supporting a load that is a heavy object, and to improve the operability as described above.
Further, since both side surfaces in the width direction of the carriage main body are portions that are easily damaged by contact with a groove or the like, the pair of rolling elements are arranged within 20 cm from one end in the longitudinal direction of the carriage main body, It is more preferable that the non-slip recess is disposed on one end side in the longitudinal direction of the cart body rather than the pair of rolling elements.

  In addition, the cargo movement cart according to the second aspect of the present invention is arranged in the groove of the cargo bed floor surface so as to have a length in the longitudinal direction of the groove, and has a placement surface on which the load is placed, and downward. A bogie main body having a hollow portion that is open at a plurality thereof, and a plurality of bogie main bodies are provided in the hollow portion at intervals in the longitudinal direction, and roll on the bottom surface of the groove to move the bogie main body in the longitudinal direction within the groove. A moving roller to be moved, a lifting mechanism for moving the carriage main body up and down with respect to the moving roller and arranging the mounting surface above the upper end of the groove when lifted, and an insertion hole provided at one end of the lifting mechanism And an operation rod for moving the cart body up and down by the elevating mechanism by tilting the other end in the longitudinal direction, and the other end of the operation rod in the longitudinal direction of the operation rod A grip that extends in a direction substantially perpendicular to It is constant.

  According to this aspect, it is easier to apply force in the pulling direction and the pushing direction to the operating rod attached to the lifting device than in the case where the grip portion is not provided at the other end of the operating rod. Since the load moving by the load moving carriage often exceeds 1t, when the load on the load moving carriage is moved by applying a pulling or pushing force to one end of the operation rod, This is extremely useful for improving the operability of the load moving carriage by the operator.

  In addition, the cargo movement cart according to the third aspect of the present invention is disposed in the groove on the cargo bed floor surface so as to have a length in the longitudinal direction of the groove, and includes a placement surface on which the load is placed and is provided below. A bogie main body having a hollow portion that is open at a plurality thereof, and a plurality of bogie main bodies are provided in the hollow portion at intervals in the longitudinal direction, and roll on the bottom surface of the groove to move the bogie main body in the longitudinal direction within the groove. A moving roller to be moved, a lifting mechanism for moving the carriage main body up and down with respect to the moving roller and disposing the mounting surface above the upper end of the groove when ascending, and one side and the other in the width direction of the carriage main body Two or more spaced apart from each other in the longitudinal direction, and each of the rolling bodies supported by the carriage main body so as to be rotatable about an axis along the height direction. Part is one side surface in the width direction of the cart body It protrudes from the square side of the.

  According to this aspect, when the load moving carriage is inserted into the groove on the lower side of the load, the load moving carriage is arranged to be biased to one side in the width direction of the groove, or the floor on which the groove is installed. Even when the surface is inclined, the outer peripheral surface of the rolling element comes into contact with the side surface of the groove before the side surface of the carriage main body. For this reason, the movement resistance of the load moving carriage is reduced and the operability is improved as compared with the case where the side face of the carriage body is in contact with the side face of the groove.

  In addition, the cargo movement cart according to the fourth aspect of the present invention is arranged in the groove of the cargo bed floor surface so as to have a length in the longitudinal direction of the groove, and has a placement surface on which the load is placed, and downward. A bogie main body having a hollow portion that is open at a plurality thereof, and a plurality of bogie main bodies are provided in the hollow portion at intervals in the longitudinal direction, and roll on the bottom surface of the groove to move the bogie main body in the longitudinal direction within the groove. A moving roller for moving the carriage main body up and down with respect to the moving roller, and an elevating mechanism for placing the mounting surface above the upper end of the groove when the carriage main body is lifted. And a housing portion for accommodating an operating mechanism for operating the lifting mechanism by the lifting mechanism is provided so as to protrude upward from the placement surface, and the placement surface side of the upper surface of the accommodation portion faces the placement surface side. Inclined parts that gradually decrease in height are formed. .

  According to this aspect, when the end portion of the load rides on the accommodation portion, the load moves to the placement surface side, and the end portion of the load falls from the accommodation portion onto the placement surface, the upper surface of the accommodation portion. Therefore, it is possible to reduce the impact when the end portion of the load falls, compared to the case where the inclined portion whose height gradually decreases is not formed. Since the load placed on the load moving carriage often has a weight exceeding 1 t, the load moving carriage may be deformed or damaged by an impact when the end of the load falls. Therefore, when there is no slope on the upper surface of the storage part, it was necessary to move the load that got on the storage part more carefully in order to reduce the impact at the time of dropping. You can reduce it and turn your attention to others. For this reason, the inclined portion on the upper surface of the accommodating portion is extremely useful for improving the operability of the load moving carriage by the operator.

  In addition, the cargo movement cart according to the fifth aspect of the present invention is disposed in the groove of the cargo bed floor surface so as to have a length in the longitudinal direction of the groove, and has a placement surface on which the load is placed and is downward. A bogie main body having a hollow portion that is open at a plurality thereof, and a plurality of bogie main bodies are provided in the hollow portion at intervals in the longitudinal direction, and roll on the bottom surface of the groove to move the bogie main body in the longitudinal direction within the groove. A moving roller, an elevating mechanism for moving the carriage main body up and down relative to the moving roller and arranging the mounting surface above the upper end of the groove when ascending, and provided at one end in the longitudinal direction of the carriage main body And a brake mechanism for projecting the stopper member downward from the lower surface of the carriage main body, and when the stopper member projects downward, a gap is formed between the lower end of the stopper member and the lower surface of the other end of the carriage main body. Pair with imaginary line The so moving roller is arranged on the carriage body side, the brake mechanism is constituted.

  The load moving carriage can be moved in the longitudinal direction in the groove by the moving roller regardless of the lifted state by the lifting mechanism. For this reason, when driving and moving the vehicle on which the loading platform is placed, the loading moving carriage is inverted in the groove so that the moving roller is up so that the loading moving carriage does not move unnecessarily in the groove. It is necessary to take measures such as placing the product on the bed floor so that the moving roller does not fall down. The above aspect is extremely useful in improving the operability of the load moving carriage because the movement of the load moving carriage by the moving roller can be restricted only by causing the stopper member to protrude downward from the lower surface of the carriage body. It is.

  In addition, the cargo movement cart according to the sixth aspect of the present invention is disposed in the groove of the cargo bed floor surface so as to have a length in the longitudinal direction of the groove, and has a placement surface on which the load is placed and is downward. A bogie main body having a hollow portion that is open at a plurality thereof, and a plurality of bogie main bodies are provided in the hollow portion at intervals in the longitudinal direction, and roll on the bottom surface of the groove to move the bogie main body in the longitudinal direction within the groove. A moving roller for moving the carriage main body up and down with respect to the moving roller, and a lifting mechanism for placing the mounting surface above the upper end of the groove when lifted. A pair of side surfaces in the width direction of the cart body is connected by a curved surface.

If a large gap is formed between the main body of the load moving carriage and the groove, the load moving carriage is arranged obliquely with respect to the longitudinal direction of the groove, and the movement of the load moving carriage in the groove becomes not smooth. The cart body has such a width dimension that a small gap is formed between the cart body and the groove.
According to the above aspect, since the upper wall portion of the carriage main body and the pair of side wall portions are connected with a curved surface, even if the gap between the carriage main body and the groove is small, the load moving carriage is within the groove. Can be rotated in the width direction. Therefore, the above aspect is extremely useful in improving the operability of the load moving carriage when the load moving carriage is reversed so that the moving roller is in the groove.

  In addition, the cargo movement cart according to the seventh aspect of the present invention is disposed in the groove of the cargo bed floor surface so as to have a length in the longitudinal direction of the groove, and has a placement surface on which the load is placed and is positioned below. A bogie main body having a hollow portion that is open at a plurality thereof, and a plurality of bogie main bodies are provided in the hollow portion at intervals in the longitudinal direction, and roll on the bottom surface of the groove to move the bogie main body in the longitudinal direction within the groove. And a frame that rotatably supports the plurality of movement rollers, and the carriage main body is moved to the plurality of movement rollers by moving the frame in one of the carriage longitudinal directions with respect to the carriage main body. And an elevating mechanism that lowers the carriage main body relative to the plurality of moving rollers by moving the carriage main body to the other, and the elevating mechanism has one end of an operating rod detachably attached to one end side in the longitudinal direction of the carriage. Tori An operating mechanism that is supported by the cart body so as to be tiltable in the longitudinal direction of the cart, and a tilting member to which one end of the operating rod is detachably attached, and one end side is coupled to the tilting member.

The link member includes the frame in the longitudinal direction of the carriage. An engagement protrusion is provided that is locked to a part of the main body of the carriage when moving to one side and restricts the movement of the frame in one direction in the longitudinal direction of the carriage.

  According to the above aspect, even when the force for operating the operating rod is too strong when moving the frame to one side of the carriage longitudinal direction, the movement of the frame in one direction of the carriage longitudinal direction relative to the carriage main body is caused by the engagement protrusion of the link member. Be regulated. Conventionally, when the force to operate the operating rod is too strong, the frame moves to one side in the longitudinal direction of the carriage with respect to the carriage body, and when it exceeds the necessary quantity, it interferes with other members unnecessarily. However, according to the above aspect, unnecessary interference with other members can be prevented even when the force for operating the operating rod is excessive. Therefore, the operator does not need to worry about the force to operate the operating rod so much, which is extremely useful for improving the operability of the load moving carriage.

  ADVANTAGE OF THE INVENTION According to this invention, the operativity of a load moving trolley | bogie can be improved, and the burden of the operator who moves a load within a pallet can be reduced.

A fixing hole 61d extending obliquely upward from the lever guide hole 61c is provided on the lower end side of the lever guide hole 61c. As shown in FIG. 7, when the lever 64 moved to the lower end of the lever guide hole 61c is accommodated in the fixing hole 61d, the stopper member 63 protrudes downward from the housing 61, and the stopper member The upward movement of 63 is restricted. When the lever 64 comes out of the fixing hole 61d and is disposed in the lever guide hole 61c, the lever 64 moves upward in the lever guide hole 61c by the urging member 62, whereby the stopper member 63 protrudes from the housing 61. Automatically return to no state. Thus, since the stopper member 63 automatically returns to the non-projecting state, the burden on the operator can be reduced.

  As shown in FIG. 8, the bottom surface of the lower end of the stopper member 63 and the lower surface of the other end of the cart body 10 in a state where the cart body 10 is in the lowered position with respect to the moving roller 20 and the lever 64 is accommodated in the fixing hole 61 d. The brake mechanism 60 is configured such that each moving roller 20 is disposed on the cart body 10 side with respect to an imaginary line IL connecting the two.

  The load moving carriage is inserted into the groove 3 disposed below the load pallet 4 among the plurality of grooves 3 extending on the floor surface 2 in the traveling direction of the vehicle. Further, the operator operates the elevating mechanism 30 with the operation rod 50 to raise the cart body 10 with respect to the moving roller 20, whereby the pallet 4 is placed on the load moving cart and floated from the floor surface 2. In this state, the operator applies a force in the vehicle traveling direction to the other end side of the operation rod 50, thereby moving the load in the vehicle traveling direction in the loading platform.

  The load moving carriage of this embodiment is provided with two rolling elements 15 spaced apart from each other in the longitudinal direction of the carriage on one side and the other side in the width direction of the carriage body 10. Each rolling element 15 is supported by the carriage main body 10 so as to be rotatable around an axis along the height direction, and a part of the outer peripheral surface of each rolling element 15 extends from one side face 10c in the width direction of the carriage main body 10 or the other side face 10c. It protrudes.

For this reason, when the load moving carriage is inserted into the groove 3 on the lower side of the load pallet 4, the load moving carriage is arranged in one side in the width direction of the groove 3, or the groove 3 is installed. Even when the load moving carriage is pressed against the side surface of the groove 3 due to the weight of the load, the outer peripheral surface of the rolling element 15 is the groove 3 before the side surface 10c of the carriage body 10. Since it contacts the side surface, the movement resistance of the load moving carriage is reduced compared to the case where the side face 10c of the carriage main body 10 is in contact with the side face of the groove 3, and the workability of the load moving carriage by the operator is improved.
Even when three or more rolling elements 15 are provided on one side and the other side in the width direction of the carriage main body 10, the same effect is obtained.

  Moreover, the rolling element 15 is rotatably supported by the cart body 10. For this reason, the cart body 10 is raised with respect to the moving roller 20 by the elevating mechanism 30, and the rolling element 15 can be brought into contact with a higher position on the inner surface of the groove when the cargo is being transported. Therefore, the cart body 10 can be prevented from falling down in the groove 3 while supporting a heavy load, and the workability of the load moving cart by the operator can be reliably improved. Is possible. Further, when the rolling element 15 is supported by the lifting device 30, the cart body 10 and the lifting device 30 are relatively movable to some extent in the cart width direction, and the protruding height of the rolling element 15 from the side surface 10c is the same as the movable range. Although the rolling element 15 is rotatably supported by the side wall 12 of the carriage body 10, the load moving carriage is pressed against the side surface of the groove 3 with a strong force due to the weight of the load. In addition, the outer peripheral surface of the rolling element 15 is surely brought into contact with the side surface of the groove 3 before the side surface 10c of the cart body 10 and is extremely useful for improving the workability of the load moving cart by the operator.

  In this embodiment, the rolling element 15 consists of a bearing, and the outer peripheral surface of the rolling element 15 is an outer ring of the bearing. The outer ring of the bearing is made by selecting materials with excellent wear resistance, corrosion resistance, load resistance, etc., so wear and deformation due to repeated use are unlikely to occur, and the cost and time required for maintenance of the load moving carriage Can be reduced.

Moreover, since the outer peripheral surface of the rolling element 15 is an outer ring of the bearing, it is advantageous for reducing the manufacturing cost of the rolling element 15 and also advantageous for reducing the space for providing the rolling element 15.
A moving roller 20 and an elevating mechanism 30 are accommodated in the hollow portion 10b of the main body 10 of the load moving carriage, and the frame 31 of the elevating mechanism 30 has a sufficient thickness to ensure the strength of the load moving carriage. It becomes. Further, since the frame 31 and the like of the elevating mechanism 30 move with respect to the cart body 10 in the hollow portion 10b, the space that is not used by the elevating mechanism 30 in the hollow portion 10b is relatively small. For this reason, being able to reduce the space for providing the rolling elements 15 is extremely useful because it can reduce or eliminate the need to change the other configuration of the load moving carriage.

Further, a support shaft 15a is inserted coaxially with the rotating shaft of the rolling element 15, and one end side and the other end side of the support shaft 15a are supported between the inner surface of the side wall 12 of the carriage body 10 and the fixed plate 15b. As described above, by fixing the fixing plate 15 b to the inner side surface of the side wall of the cart body 10, the rolling elements 15 are rotatably supported by the cart body 10.
For this reason, the space of the attachment structure which attaches the rolling element 15 to the trolley | bogie main body 10 can also be made small, and the necessity for changing the other structure of a load movement trolley | bogie can be reduced or eliminated.
Moreover, the rolling element 15 can be firmly supported by the cart main body 10 with a simple configuration, and the replacement work of the rolling element 15 can be easily performed.

  Each rolling element 15 is disposed on one end side or the other end side of the carriage body 10. Preferably, each rolling element 15 is arranged within 20 cm from one end or the other end of the cart body 10, and more preferably, each rolling element 15 is arranged within 10 cm from one end or the other end of the cart body 10. Thus, since each rolling element 15 is arrange | positioned at the one end side or the other end side of the trolley | bogie main body 10, even when the load moving trolley is diagonally arrange | positioned in the horizontal direction within the groove | channel 3, the side surface of the trolley | bogie main body 10 is shown. Each rolling element 15 can be brought into contact with the side surface of the groove 3 before 10c.

A grip portion 52 extending in a direction substantially orthogonal to the longitudinal axis of the operation rod 50 is fixed to the other end of the operation rod 50.
When such a grip portion 52 is not provided, for example, when only the grip portion coaxial with the longitudinal axis of the operation rod is provided on the other end side of the operation rod, the weight of the load moved by the load moving carriage When it becomes about 1 t, a considerable burden is applied to the operator who applies force in the pulling direction and the pushing direction to the other end of the operation rod.
In the present embodiment, since the grip portion 52 is fixed to the other end side of the operation rod 50, it is easy to apply a pulling and pushing force to the operation rod attached to the lifting device 30, and the load movement by the operator This is extremely useful for improving the operability of the cart.

In addition, since the pair of grip portions 52 extending in opposite directions to each other are fixed to the other end of the operating rod 50, the force in the pulling direction and the pushing direction can be applied to the other end side of the operating rod 50 in a balanced manner. The operability of the load moving carriage by the operator can be further improved.
Further, an operation rod hanger made of a pair of hook-shaped members, a pair of ring-shaped members, or the like is provided on the side wall of the truck bed 1 and the pair of grip portions 52 are respectively placed on the hook-shaped members, or The operation rod 50 can be easily fixed or hung on the loading platform 1 by passing the grip portions 52 of each of them in each ring-shaped member. Here, since the pair of grip portions 52 are fixed to the operation rod 50, it is possible to reduce the possibility that the grip portions 52 fall off from the hook-shaped member or the ring-shaped member due to vibration of the track or the like.

In addition, an accommodation portion 13 is provided at one end in the longitudinal direction of the carriage main body 10 so as to protrude above the placement surface 10a and accommodate the operation mechanism 34, and the load movement carriage is placed in the groove 3 so that the moving roller 20 is located below. In the state where the carriage main body 10 is arranged at the lowered position with respect to the moving roller 20, a plurality of first slip stoppers are provided at portions arranged outside the grooves 3 on both sides in the carriage width direction in the accommodating portion 13. A groove (concave portion) 13b is provided.
Since the load moving cart is loaded with a load exceeding 1 t, it is made of a metal material so as to withstand repeated use and is not light. In addition, it is necessary for the operator to change the position and direction of the load moving carriage according to the position and moving direction of the moving load. When changing the position or direction of the load moving carriage disposed in the groove, the operator lifts the load moving carriage by grasping the portion protruding from the groove in the load moving carriage, that is, the accommodating portion 13 of the carriage main body 10. . Here, since the worker wears a work gloves for safety, the operator's hand is easy to slip on the accommodating portion 13 when grasping the conventional load moving cart, and the operability of the load moving cart is good. I couldn't say that.
In the present embodiment, since the storage portion 13 is provided with a plurality of first anti-slip grooves 13b, the hand of the worker wearing a work gloves or the like is difficult to slide on the storage portion 13, and the load moving carriage of the worker Operability can be improved.

In addition, in a state in which the load moving carriage is arranged in the groove 3 so that the moving roller 20 is on the upper side, a plurality of second slip stoppers are provided in portions of the housing portion 13 that are arranged outside the grooves 3 on both side surfaces in the carriage width direction. A groove 13b is provided.
For this reason, when the load moving carriage is arranged in the groove 3 with the moving roller 20 facing upward, or when the load moving carriage arranged in the groove 3 is lifted, the load moving carriage by the operator is used. The operability can be improved.

The side surface in the cart width direction of the accommodating portion 13 of the cart body 10 is a portion that is easily damaged by contact with the groove 3 or the like. For this reason, the non-slip seal affixed to the side surface in the cart width direction and the rough surface portion formed by rough surface processing such as shot blasting are liable to be peeled off or clogged when the load moving cart is used.
In the present embodiment, the anti-skid grooves 13b and 13c are formed by cutting the side surface in the cart width direction into a concave shape, so that the functions of the anti-skid grooves 13b and 13c are maintained even when the load moving carriage is used repeatedly. The

In addition, an inclined portion 13 a whose height gradually decreases toward the placement surface 10 a side is provided on the placement surface 10 a side on the upper surface of the housing portion 13.
The load placed on the load moving carriage may exceed 1 t, and the end of the load pallet 4 may ride on the accommodating portion 13 during the load moving operation. When the pallet 4 riding on the storage unit 13 moves to the mounting surface 10a side of the cart body 10 and the end of the pallet 4 falls from the storage unit 13, the weight of the load is placed on the mounting surface 10a of the cart body 10. And impact force according to the fall height is added. The carriage main body 10 is placed so that a heavy object is placed and is made to have sufficient strength. However, if the fall height is high, the impact force becomes considerably large with respect to the weight of the load. The main body 10 may be deformed. For this reason, when the inclined portion is not provided on the upper surface of the accommodating portion as in the conventional load moving carriage, the load on the accommodating portion is moved more carefully in order to reduce the impact at the time of dropping. It was necessary to be concerned.
In the present embodiment, since the inclined portion 13a is provided on the placement surface 10a side on the upper surface of the accommodating portion 13, the drop height is reduced, the concern can be reduced, and the attention can be turned elsewhere. Therefore, the inclined portion 13a on the upper surface of the accommodating portion 13 is extremely useful for improving the operability of the load moving carriage by the operator.

Further, a brake mechanism 60 for projecting the stopper member 63 downward is provided at one end of the cart body 10 in the longitudinal direction. When the stopper member 63 projects downward, the lower end of the stopper member 63 and the other end of the cart body 10 are provided. The brake mechanism 60 is configured such that the moving roller 20 is disposed on the cart body 10 side with respect to an imaginary line IL connecting the lower surface.
The load moving carriage can be moved in the longitudinal direction of the carriage in the groove 3 by the moving roller 20 regardless of the raising / lowering state by the raising / lowering mechanism 30. For this reason, conventionally, when the vehicle on which the loading platform 2 is mounted is driven and moved, the loading moving cart is arranged so that the moving roller 20 is on the upper side so that the loading moving cart does not move unnecessarily in the groove 3. In the groove 3 or a load moving carriage is placed on the floor 2 so that the moving roller 20 does not go down.
In the present embodiment, since the movement of the load moving carriage by the moving roller 20 can be restricted only by causing the stopper member 63 to protrude downward from the lower surface of the carriage main body 10, the operability of the load moving carriage can be improved. It is extremely useful.

Moreover, between the mounting surface 10a and the pair of width direction side surface 10c in the trolley | bogie main body 10 is connected by the curved surface.
Here, if a large gap is formed between the carriage main body 10 and the groove 3 of the load moving carriage, the load moving carriage is arranged obliquely with respect to the longitudinal direction in the groove 3, and the load in the groove 3 is The movement of the moving carriage is not smooth. For this reason, conventionally, the width of the carriage body 10 is made to be about 3 mm smaller than the width of the groove 3 so that a gap of 1 to 2 mm is formed on each side of the carriage body 10 in the width direction. There are many cases.
Thus, since the gap with the groove 3 is small, conventionally, in order to reverse the load moving carriage in the groove 3 so that the moving roller 20 is on the upper side, the load moving carriage is taken out of the groove 3 and the load moving carriage is It was necessary to reverse.
In this embodiment, since the mounting surface 10a of the cart body 10 and the pair of side surfaces 10c in the width direction are connected by a curved surface, it is compared with the case where the mounting surface 10a and the side surface 10c are connected at an acute angle. In addition, the distance between the connecting portion between the mounting surface 10a and the one side surface 10c and the lower end of the other side surface 10c (the size in the diagonal direction of the cross section of the bogie main body 10) is reduced, and the load moving carriage is reversed in the groove 3 It becomes possible to make it. Therefore, this embodiment is extremely useful for improving the operability of the load moving carriage.

In addition, since the curved surface is formed by molding R that can be performed when the upper wall portion 11 and the pair of side wall portions 12 are integrally formed by bending, the dedicated cost for forming the curved surface. The manufacturing cost can be reduced.
Note that the curved surface can be formed by machining instead of molding R.

  It should be noted that the present invention is not limited to the configuration of the above-described embodiment, and can be appropriately modified or improved within a scope not departing from the gist of the present invention. Are also included in the scope of rights of the present invention.

  For example, in the above-described embodiment, a load moving carriage used in a loading platform of a vehicle such as a truck is shown. However, the loading moving carriage may be used even in a freight train or a container vehicle in which a groove 3 is formed on the floor surface of the loading platform. Is possible.

  Moreover, in the said embodiment, although the some 1st anti-skid groove | channel 13b and the some 2nd anti-skid groove | channel 13c are provided in the both sides | surfaces of the accommodating part 13, respectively, it respond | corresponds to the some 1st anti-slip groove 13b. It is also possible to provide a single recess at a position and provide a single recess at a position corresponding to the plurality of second anti-slip grooves 13c. Even in this case, it is difficult for the operator's hand wearing a work gloves or the like to slide on the accommodating portion 13. Note that the operability of the load moving carriage by the operator can be further improved if the plurality of first anti-slip grooves 13b and the plurality of second anti-slip grooves 13c are provided.

  Moreover, in the said embodiment, although the thing using the needle bearing without an inner ring was shown as the rolling element 15, the needle bearing with an inner ring can also be used as the rolling element 15, and it is also possible to use other roller bearings. is there. Further, it is possible to use a ball bearing as the rolling element 15.

  Furthermore, it is also possible to use a ball transfer bearing manufactured by Atec Co., Ltd., in which a metal ball is rotatably supported by a plurality of small support metal balls as the rolling element. Even in this case, if a part of the outer peripheral surface of the metal sphere protrudes from the side surface 10c of the carriage main body 10, the same effects as described above can be obtained.

  Moreover, in the said embodiment, although the outer peripheral surface of the rolling element 15 showed what was an outer ring | wheel of a bearing, even if an annular member was fitted to the outer ring | wheel of a bearing and the outer peripheral surface of the rolling element 15 was comprised with the annular member, it is. good.

  In the above embodiment, a pair of grip portions 52 is provided on the other end side of the operation rod 50. However, the grip portion 52 may be only one of the pair of grip portions 52. Yes, even in this case, the presence of the grip portion 52 makes it easier for the operator to apply force in the pulling direction and pushing direction to the operation rod 50.

  In the above embodiment, the upper wall portion 11 and the pair of side wall portions 12 are integrally formed by bending a plate-shaped member such as a steel plate, but the upper wall portion 11 is configured. It is also possible to make the cart body 10 by connecting the steel plate and the steel plate constituting the side wall portion 12 by welding.

A cargo movement cart according to a second embodiment of the present invention will be described below with reference to FIGS.
In the second embodiment, with respect to the first embodiment, the configuration of the operation mechanism 34, the configuration of each slope member 33, and a plurality of concave portions provided on both side surfaces in the carriage width direction in the accommodating portion 13 are provided. The first anti-slip groove and the plurality of second anti-slip grooves are modified, and other configurations are the same as those of the first embodiment.

  As shown in FIGS. 11 and 12, the operation mechanism 34 of the present embodiment is provided with an insertion hole 34a to which one end of the operation rod 50 is detachably attached, and an insertion hole 34a, as in the first embodiment. The tilting member 34b supported to be tiltable in the longitudinal direction of the carriage to the portion 13 is connected to one end side of the tilting member 34b so that the one end side can tilt, and the other end side is connected to one end side of the frame 31 of the lifting mechanism 30 to be tiltable. Link member 34c. In the first embodiment, the tilting member and the link member are provided, although not explicitly shown.

  Also in this embodiment, as in the first embodiment, the operation roller 50 attached to the insertion hole 34a is tilted so as to stand in a substantially vertical direction, so that the moving roller 20 and the carriage main body 10 are closest to each other (downward). The cart main body 10 moves to a position (rising position) raised with respect to the moving roller 20 by tilting the operation rod 50 in the longitudinal direction of the cart so as to fall from the vertical position.

  When the operating rod 50 is tilted in the carriage longitudinal direction when moving to the raised position, the tilting member 34b is also tilted in the carriage longitudinal direction, whereby one end side of the tilting member 34b is the other end side in the carriage longitudinal direction (the accommodating portion 13). Move toward the side that is not provided. For this reason, the link member 34c also moves toward the other end side in the cart longitudinal direction, and the frame 31 of the lifting mechanism 30 connected to the other end side of the link member 34c also moves toward the other end side in the cart longitudinal direction. To do. As a result, as in the first embodiment, each elevating roller 32 of the elevating mechanism 30 rolls on the inclined surface of each inclined member 33 toward the top thereof, and the main body 10 is moved upward with respect to the moving roller 20. Move to.

  In the present embodiment, an engaging protrusion 34d is provided between the one end side connecting portion and the other end side connecting portion in the longitudinal direction of the link member 34c. In this embodiment, the engaging protrusion 34d is shortened from the link member 34c. It protrudes in the hand direction and upward. The engaging protrusion 34d tilts the operating rod 50 to which the operating rod 50 is attached in the longitudinal direction of the carriage, the link member 34c moves toward the other end side in the longitudinal direction of the carriage, and each lifting roller 32 is moved to each slope member 33. When it moves to the predetermined position above, as shown in FIG. 12, it engages with a part of the cart body 10 from one end side in the longitudinal direction of the cart. For this reason, even if the force applied to the operating rod 50 is too large when the lifted position is set, each elevating roller 32 moves to the other end side in the longitudinal direction of the carriage, greatly exceeding the predetermined position on each slope member 33. Is prevented.

Each raising / lowering roller 32 moves on the inclined surface of each slope member 33 toward the top, and then fits into a recess 33a provided on the top of each slope member 33 (see FIG. 13). This state is a state where the elevating roller 32 is moved to the raised position, and each elevating roller 32 is moved to the predetermined position on each slope member 33. Conventionally, as shown in FIG. 14, a movement restricting protrusion 33 b is sometimes provided on the top of each slope member 33 in order to restrict the movement of each elevating roller 32 to the other end side in the longitudinal direction of the carriage. However, even if the movement restricting protrusion 33b is provided, if the force applied to the operation rod 50 is too large, the elevating roller 32 may ride on the movement restricting protrusion 33b. And if the raising / lowering roller 32 gets on the movement control protrusion 33b, the trolley | bogie main body 10 will move to the position which raised too much with respect to the moving roller 20. FIG. On the other hand, a regulation pin for restricting the downward movement of the lifting mechanism 30 with respect to the carriage body 10 is provided in the hollow part 10b of the carriage body 10 so that the lifting mechanism 30 does not drop or protrude excessively from the hollow portion 10b of the carriage body 10. Is provided. For this reason, when the raising / lowering roller 32 rides on the movement restricting protrusion 33b and the carriage body 10 moves to a position where it is excessively raised with respect to the moving roller 20, the raising / lowering mechanism 30 contacts the restriction pin from above. When this contact is repeated or when the elevating mechanism 30 is pressed against the restricting pin with a large force, the restricting pin may be damaged, and the elevating mechanism 30 may drop from the hollow portion of the cart body 10.
However, in the present embodiment, the engagement protrusions 34d prevent each lifting roller 32 from moving to the other end side in the longitudinal direction of the carriage greatly exceeding the predetermined position on each slope member 33. Thus, since it is not necessary to provide the movement restricting projection 33b on the top of each slope member 33, the lifting mechanism 30 is not pressed against the restricting pin with a large force even if the force for tilting the operating rod 50 is too large.

  Further, in the first embodiment, as shown in FIG. 2 and the like, a plurality of first anti-skid grooves 13b and a plurality of second slips, which are slot holes, are formed on both side surfaces of the accommodating portion 13 in the carriage width direction. Although the retaining groove 13c is provided, in the present embodiment, a plurality of first anti-slip groove holes 13e penetrating the plate-like members constituting the side surfaces of the housing portion 13 as concave portions on both side surfaces in the carriage width direction in the housing portion 13. And a plurality of second anti-slip grooves 13f.

  As described above, since the plurality of recesses provided to prevent slipping on both side surfaces in the carriage width direction of the storage portion 13 penetrates to the inside of the storage portion 13, the air permeability in the storage portion 13 is improved. Further, it becomes possible to suppress rust of the operating mechanism 34 disposed in the accommodating portion 13 and deterioration of the lubricating oil, and because these recesses can be formed by punching, the manufacturing cost can be reduced. In addition, the weight can be reduced.
