Description

  The present invention is a traveling surface which is a bulky transported object, for example, when installing or moving various devices in various factories, construction sites, etc. It is possible to adjust the height of the gap with the running surface, such as by lifting it up to a greater distance, or lifting the devices slightly higher even temporarily to avoid when there is a protrusion on the running surface. It relates to a roller cart with a jack.

  Conventionally, in order to move and transport various equipment and other transported objects, these are mounted on a carriage having wheels that can travel on a traveling surface. There has also been proposed a cart that can cope with this by providing a jack so as to be moved up and down in order to transfer the loaded transported object to a mounting surface such as a shelf at a predetermined height position. For example, it is a transport cart as shown in Patent Document 1, and a self-propelled wheel pressure increasing type pull cart as shown in Patent Document 2.

  In the transport cart shown in Patent Document 1, a jack for raising and lowering the mounting table is arranged on a cart body provided with wheels, and the mounting table is raised and lowered by a leg member that is raised and lowered by a jack operation. . In the traction cart shown in Patent Document 2, a jack is arranged on a traction cart that can be inserted below the end of the transport cart, and the end of the transport cart is pushed up by a jack operation. The wheel pressure is increased so that the transport carriage can be efficiently pulled.

  However, since the carriage of Patent Document 1 is configured to move up and down by a jack and a leg member, the carriage placed on the carriage main body is mounted on the carriage, for example, to transport various heavy industrial equipment. However, even if it is lifted, it cannot be supported sufficiently, and its lifting operation is almost difficult. The towing cart of Patent Document 2 merely increases the wheel pressure against the running surface of the towing cart itself by lifting the jack from the lower side to the end of the conveying cart to pull the conveying cart, and is conveyed by the jack. It does not lift the object itself.

  Therefore, the present invention was created in view of the existing circumstances as described above, and the purpose thereof is to carry various materials such as various heavy equipment on a carriage, for example, When there is a protrusion on the bottom, the transfer work can be carried out smoothly by lifting it so as to increase the distance from the traveling surface, or even lifting it temporarily to avoid the protrusion on the traveling surface during transportation. It is in providing the roller trolley | bogie with a jack which was made.

In order to solve the above-described problem, in the present invention, a jack 10 that raises and lowers a conveyed product L mounted on the cart body 1 is arranged on the cart body 1 provided with wheels 3 (23, 24, 27). Thus, the jack 10 is provided in the cart main body 1 and is characterized in that the upper end portion of the piston rod 13 at the time of non-operation is positioned on the upper side wall 4 of the cart main body 1.

In the roller trolley with a jack according to the present invention configured as described above, the trolley body 1 freely moves on the running surface by the wheels 3 (23, 24, 27) provided on the trolley body 1 itself. The transported object L that can travel and is mounted on the cart body 1 is transported by the jack 10 when, for example, a projecting portion is provided on the bottom surface of the transported object L or a protrusion is present on the travel surface. Even if the L is temporarily lifted and positioned at a predetermined height position, the contact with the projecting surface of the projecting portion of the conveyed product L or the projection of the traveling surface of the conveyed product L, etc. during traveling Avoid it.
The jack 10 itself is accommodated in the cart body 1 by screwing the connecting plate 12 of the jack outer wall 11 and the upper wall 4 of the cart body 1 so that the entire cart body 1 including the jack 10 is compactly configured.
The connection port 5 provided on the side wall of the cart body 1 facilitates connection with the hydraulic oil supply pipe P that supplies hydraulic oil to the supply coupler 14 of the jack 10.
The cart body 1 provided with the drive mechanism 20 moves the traveling object L mounted on the cart body 1 directly and travels, and the cart body 1 having wheels 3 that roll freely without incorporating the drive mechanism 20. Supports the load when moving the transported object L even if it is auxiliary.

  Since the present invention is configured as described above, for example, when there is a protrusion on the bottom surface of the transport object L mounted on the carriage body 1 or there is a protrusion on the traveling surface, the transport object is provided by the jack 10. By lifting L even temporarily, it is possible to avoid, for example, contact between the conveyed object L and the traveling surfaces associated with these protrusions.

  That is, in the present invention, the jack 10 for raising and lowering the conveyed product L mounted on the carriage main body 1 is provided in the carriage main body 1, and the upper end portion of the piston rod 13 at the time of non-operation is positioned on the upper wall 4 portion of the carriage main body 1. This is because the transported object L can be temporarily lifted as necessary during transportation, and the compact structure of the cart body 1 can be realized.

  Moreover, the jack 10 itself is accommodated in the cart main body 1 by screwing the connecting plate 12 provided on the upper end portion of the jack outer wall 11 in a contact state with the lower surface of the upper side wall 4 of the cart main body 1. Thus, for example, the so-called low-profile, flat-type jack 10 can be easily incorporated into the cart body 1 and the entire cart body 1 including the jack 10 can be configured compactly, so that it can be handled as a roller cart having wheels 3. Also make it easier.

  A connecting port 5 is provided on the side wall of the cart body 1, and a supply coupler 14 of the jack 10 is disposed so as to go out through the connecting port 5, thereby supplying a working oil supply pipe P for supplying the working oil to the jack 10. And further, for example, supply control of hydraulic oil when using a plurality of units can be easily performed.

  By arranging the drive mechanism 20 in the cart body 1 and making it self-propelled, it is possible to directly move the traveling object L mounted on the cart body 1 and to roll freely without incorporating the drive mechanism 20. For example, by mounting the transported object L in combination with the self-propelled cart body 1 as appropriate, the load of the transported object L when moving and traveling can be supplemented. It can be supported in a shared manner and transported safely and stably.
