Description

[Detailed Description of the Invention] The present invention relates to a cart for transporting a flanged roller attached to a pallet of a Dwight Lloyd sintering machine to a predetermined location after being removed from the pallet when replacing the roller.

Conventionally, when the flanged roller attached to the pallet of a sintering machine becomes worn or damaged, it is necessary to transport the roller to a designated location for replacement. Because of this, it is difficult to transport and requires two to three people to put it on an existing trolley, which poses safety issues, so there is a strong need for a trolley that is both safe and easy to transport.
The inventors of the present invention have previously applied
No. 55-130085) devised a flanged roller transport trolley, but as shown in FIG.
Open the chuck plates 5'a, 5'a by lifting both ends of the flange roller 19' with your hands.
The flange roller 19' and the cart are aligned so that the body is sandwiched between the notch holes 6', 6' provided in the chuck plates 5'a, 5'a, but both chuck plates, which were open at this time, are aligned. When the rollers 5'a and 5'a rotated downward, there was a risk of getting one's hand caught between the collar or body of the roller 19' and the chuck plates 5'a and 5'a. In addition,
In FIG. 5, 1' is a horizontal frame, 2' is a tilted frame, 7' is an arm, 12' is a handle, 13' is a foot pedal, and 15' is a wheel.

Therefore, the present invention allows the chuck plate to be opened and closed easily using a lever, and also prevents the chuck plate from easily rotating and lowering when the chuck plate is opened.

The present invention is a transportation cart that eliminates the danger of pinching a flanged roller.

This invention will be explained with reference to FIGS. 1 to 4. The flanged roller carrier according to this invention has semicircular cut holes 6, 6 in the center of left and right chuck plates 5a, 5a. are provided so as to face each other, and a rod-shaped horizontal frame 1 is arranged on the right-hand symmetrical line of the left and right chuck plates 5a, 5a, so that both chuck plates 5a, 5a
It is a transportation cart in which arm parts 7 are fixedly installed at the front and rear of the vehicle, and the front and rear arm parts 7 are pivotally supported by a horizontal frame 1, and a pedestal 8 provided immediately after the front arm part 7a is inserted through the horizontal frame 1. A block 9 that moves up and down on the front side of the pedestal is provided, and the block 9 and the front arm 7a are connected by a link 10 arranged in a figure-eight shape, and an upward-facing figure-shaped arm 11 is attached to the pedestal 8 as a pivot. The block 9 is attached to the upper surface of the front part 11a of the arm.
Further, a cable 17 is connected to the rear end 11b of the arm 11, and the cable 17 is slidably fixed to the horizontal frame at a position where the rear end 11b of the arm 11 can be lowered.

An embodiment of the present invention will be described based on FIGS. 1 to 4.

Reference numeral 1 denotes a rod-shaped horizontal frame, and a pivot 3 having wheels 15, 15 projecting downward is provided at the rear end. A tilting frame 2 tilting rearward and upward is attached to the rear end of the pivot 3 via a locking mechanism 4 so as to be foldable. The tilting frame 2 has a handle 12 fixedly attached to its upper end and a foot pedal 13 fixedly attached to its lower part. Further, the locking mechanism 4 includes a base portion 1a fixed to the pivot shaft 3, and a base portion 1a fixed to the inclined frame 2.
A folding part 2a which is pivoted at the upper part 22, and a locking/unhooking tool 2 which is pivoted to the lower part of the base part 1a, has a foot lever 14, and can be locked to the lower part of the folding part 2a.
It is composed of 3. 5 is a plate-shaped chuck,
The left and right chuck plates 5a, 5a are provided with semicircular notches 6, 6 in the center so as to face each other, and arm portions 7a, 7, each consisting of three pieces, are provided at the front and rear of the upper surface.
b is erected by welding its base end.
And upper end overlap portions 24, 24 of each arm portion 7a, 7b
The horizontal frame 1 is inserted through the hole. In other words, the plate-like chuck 5 is attached to the horizontal frame 1 with the front and rear arms 7.
It is pivotally connected via a and 7b so that it can be opened and closed. Further, a box-shaped pedestal 8 is inserted into the horizontal frame 1 immediately behind the front arm 7a, a cylindrical bearing 25 is fixed to the upper surface of the pedestal 8 by welding, etc., and a vertical pin 8a is erected in front of the cylindrical bearing 25. It is set up. Reference numeral 9 denotes a U-shaped block with a downward cross section, and a vertical pin 8a is inserted into a guide tube 26 fixed at the center of the rear side, and the block moves up and down along the guide tube 26.
The block 9 is placed horizontally so as to cover the front arm 7a, and the block 9 and the front arm 7a are connected to the bolt 27 by four links 10 on the front and rear sides.
It is pivoted and connected. 11 is a dogleg-shaped arm, the central bent part 28 is pivotally connected to the bearing 25 of the base 8, and the front part 11a is inserted into the lower surface of the block 9 and comes into contact with it. In addition, the rear end 11b of the doglegged arm 11
The front end of the cable 17 is connected to the arm 11.
The cable 17 is placed in a position where the rear end 11b can be lowered.
is slidably fixed to the horizontal frame 1, and the middle portion passes through a duct 18, and the rear end is connected to the lever 16 of the handle 12.

In other words, the plate-like chuck 5 is configured to be opened and closed by an opening/closing mechanism consisting of an arm 7, a pedestal 8, a block 9, a link 10, a dogleg arm 11, etc., which are operated by pulling the cable 17.

However, the roller 19 is on the floor with its flange 21
If the vehicle is placed with the vehicle facing up, in order to drive it to the designated location, a person must first move the vehicle to the roller 1 position.
When the lever 16 is squeezed at this point, the cable 17 connects the rear end 11b of the arm 11 and raises the front part 11a, so that the block 9 rises. The front arm portion 7a connected to the block 9 via a link 10 has an upper end overlapping portion 2 as shown in FIG.
4 as a fulcrum and is pulled up by the link 10 to open the left and right chuck plates 5a, 5a as shown by the chain lines.

Therefore, when the plate-shaped chuck 5 is placed over the roller 19 and the lever 16 is released, the chuck descends under the weight of the chuck plates 5a and 5a to return to its original closed state. As a result, the body portion 20 of the roller 19 is sandwiched between the chuck plates 5a, 5a at the notch holes 6, 6.

Next, when a person holds the handle 12 of the trolley and kicks up the foot pedal 13, the front part of the trolley floats and the plate chuck 5 hooks onto the collar 21 of the roller 19 and lifts it up.At the same time, while holding the center of gravity of the trolley with both hands, Can be transported to the location. After arriving at the designated location, the front part of the cart is lowered, the roller 19 is placed on the floor, and the lever 1 is
When the chuck 6 is gripped again, the chuck 5 is opened as described above, and the carriage is separated from the rollers 19.

In addition, in order to make it easier to store the transport trolley after use,
When the foot lever 14 of the latching mechanism 4 is stepped on, the latching/unhooking tool 23
Since it is removed from the folding part 2a, the inclined frame 2 is folded together with the folding part 2a, making it easy to store.

According to this invention, flanged rollers are heavy, round, and slippery, so they are very difficult to carry by hand, but even one person can easily and safely transport this roller, and the structure is simple. It has the advantage of being foldable.
