[0003]

However, in this conventional cart, the loading platform is merely a platform. Therefore, when changing the orientation of the equipment placed on the loading platform, the entire cart must be turned or the equipment must be changed. I had no choice but to lift and change direction. For this reason, the former requires a large space, and the latter requires a large amount of labor and is dangerous when the equipment is heavy. In addition, a device housed in a position lower than the position of the cart bed could not slide the device sideways and put it on the cart (similarly to removal).

[0004] It is an object of the present invention to be able to change the direction of the equipment mounted on a cart even in a place such as a rack room where the passage is narrow and the entire cart cannot be changed, and which is lower than the cart bed. It is an object of the present invention to provide a cart for transporting equipment which enables the equipment to be slid and pushed in from the cart or to be slid out of the rack and drawn out of the cart even with respect to the rack position.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a cart for transporting equipment capable of lifting and lowering equipment by using a hydraulic jack. In order to achieve the above object, the loading platform is rotated in a horizontal plane. The equipment can be turned in narrow passages without changing the direction of the cart, and by providing a pull-out plate on the cart bed, equipment stored in a lower position than the cart bed can be installed. It is designed to be able to be skid and put on a cart.

That is, in the equipment transport cart according to the present invention, the lift arm has a two-stage structure in the equipment transport cart in which the loading platform on which the equipment is mounted is supported by a hydraulic jack-driven lift arm on a wheeled support base. In addition, the loading platform is provided with a rotating plate rotating on a horizontal plane around a rotation axis on an upper surface thereof, and a drawer-type plate accommodated in the loading platform.

[0007] In the cart for transporting equipment of the present invention, the rotating plate may be supported by a plurality of ball bearings or roller bearings embedded in the surface of the carrier, and may smoothly rotate around the rotating shaft. It is characterized by the following.

Further, in the cart for carrying equipment of the present invention, the rotating plate comprises a disk having a notch in which a portion protruding from the carrier is cut off when the rotating plate is always installed, and the rotating plate is provided only in a predetermined rotation range of the rotating plate.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on embodiments of the present invention with reference to the accompanying drawings. FIG.
1 is a perspective view showing an embodiment of the cart for transporting equipment of the present invention. In FIG. 1, 1 is a support, 2 is wheels mounted on the support 1 so that the cart can be moved, and 3 is 2
A pandagraph type lift arm having a stepped configuration, 4 is a loading platform, 5 is a rotating plate that rotates in a horizontal plane formed on the upper surface of the loading platform 4, 6 is a drawer type plate accommodated in the loading platform 4, 7 is a hydraulic pressure The jack and 8 are slits for one end of the lift arm 3 to slide. Also,
As shown, the cart is provided with a push handle 14.

The height of the bed 4 is adjusted by a two-stage lift arm 3. Now, when adjusting the length of the hydraulic jack 7 itself, one end of which is attached to the support base 1 and the other end of which is attached to the lateral arm of the lift arm 3, the inclination of one end of the lift arm 3 changes at the point c, and d At this point, one end of the lift arm 3 moves along the slit 8 and the inclination changes. Thus, the carrier 4 can be raised and lowered (driving of the lift arm 3).
In this case, the loading platform 4 also has a similar mounting structure to the lift arm 3.

Next, a loading platform which is a feature of the present invention will be described. FIGS. 2A and 2B show the carrier 4 in FIG. 1 in a top view and a side view, respectively. In FIG. 2, reference numeral 4 denotes the above-described loading platform, 5 denotes a part of the loading platform, which is rotatably disposed around the rotation axis 9, and is supported by a plurality of ball bearings 10 embedded in the surface of the loading platform 4. This is a rotating plate on which the device is mounted (see FIG. 1 for the overall configuration). The role of this ball bearing 10 is not only for the rotating plate 5 to rotate smoothly, but also when heavy equipment is placed on the plate, even if it is located away from the rotating shaft. This is also to prevent a burden on the rotating mechanism. Note that the ball bearing 10 may be a roller bearing.

The rotary plate 5 may be provided at any position on the upper surface of the loading platform 4. One of the purposes of providing the rotary plate is to place the device mounted on the cart in a narrow passage without changing the direction of the entire cart. Considering that the direction of the rotation plate 5 is changed, it is desirable that the rotating plate 5 does not protrude from the upper surface of the carrier 4 as much as possible. The shape of the rotating plate is not limited to a square as shown, but may be any shape such as a rectangle or a circle.

Next, in the equipment transport cart of the present invention, as shown in FIG. 2, the carrier 4 has a drawer-type plate 6 accommodated in the carrier. This makes it possible to slide the device at the highest position of the loading platform, that is, the device at a position lower than the upper surface of the rotating plate 5 as it is from the rack, and place it on the pull-out plate. Also in this case, the overall adjustment of the height of the cargo bed is performed by the expansion and contraction of the lift arm 3 (see FIG. 1).

In the above, it has been described that it is desirable that the rotating plate 5 does not protrude from the upper surface of the carrier 4 as much as possible. However, in the equipment in the rack, a gap may be formed between the rack and the rotating plate 5 depending on the mounting state. In such a case, installation of equipment,
It is easier to work if a part of the rotating plate 5 enters the rack at the time of removal.

In order to meet such needs, in a modified example of the cart of the present invention, the shape of the rotating plate 5 is
As shown in FIG.
When rotating above, the hatched portion is cut off from the disk having the rotation center P and the radius r to obtain a shape as shown in FIG.
According to this, the rotating plate 5 does not protrude from the upper surface of the loading platform 4 even in a narrow passage, so that the cart can be easily moved, and when a part of the rotating plate 5 is to be put into the rack, the rotating plate 5 5 can be rotated by 90 °, as shown in FIG. 3 (c).

Another modification of the cart of the present invention is shown in FIG.
As shown in a top view and a side view, respectively, in FIG. 4B and FIG. 5B, the rotating plate 5 is configured to rotate on a pedestal 11 separated from the loading platform 4, and the pedestal 11 is pulled out of the loading platform 4. And slides along the groove 12 formed in a direction perpendicular to the direction of insertion and extraction. At this time, it is conceivable to smooth the movement of the pedestal between the bottom surface of the pedestal 11 and the groove 12 via a ball bearing 13 or the like. According to this, when equipment is inserted into the rack, a part of the bed 4 on which the rotating plate 5 is attached is slightly slid in the direction of the arrow shown in FIG. The goal can be achieved.

In still another modification of the rotating plate of the cart according to the present invention, the rotating plate has a through hole, and the rotating plate is clamped by inserting a pin into a hole formed in the carrier through the through hole. Such a configuration is adopted. According to this modified example, it is possible to prevent an accident such as accidental rotation of the rotating plate 5 from occurring.

A modified example of the pull-out plate of the cart according to the present invention is constituted by a frame body which leaves only the periphery of the illustrated pull-out plate 6 (FIGS. 1 to 4). This is because the size of the equipment is usually fixed, so by properly designing the size of the frame, there is no obstacle to mounting the equipment on it, and it is composed of a plate There is an effect that the weight of the cart can be reduced as compared to doing so.

[0022]

According to the present invention, since the cart has the rotating plate, by mounting the device on the rotating plate, the direction of the device can be easily changed when the device is mounted on the rack. Unlike the conventional art, there is no need to manually replace heavy equipment on the cart, and work efficiency such as adjustment of equipment and connection of cables is greatly improved.

Further, since the cart of the present invention has a drawer type plate accommodated in the carrier, the equipment mounted on the rack at a position lower than the upper surface of the carrier (including the rotating plate) is detached and pulled out. It is very useful in some cases. In addition, this pull-out plate can be used even if the lift arm is most retracted (in the prototype, approximately 24 cm above the floor).
m) It is also effective when the loading platform is too high.

With respect to the cart of the present invention, the respective effects of the modified examples have been described together in the description of each modified example, so that the description thereof will be omitted here.
