Description

The present invention relates to an assembled belt type track roll type carrier.

A hand-push type carriage is widely used in manufacturing plants and the like as a simple means of transporting materials, products, and the like. Wheels are generally used as the traveling mechanism of this hand-push type carriage.
In order to get over the steps of the travel path, the carriage is required to have wheels with a certain diameter. However, there is a limit to how large a step can be handled only by the size of the wheel. In addition, when the road surface is rough, the vehicle using wheels is subject to a large load at the time of start-up, which may cause problems such as rattling, shock, and noise during travel.

On the other hand, trucks using caterpillars (registered trademark) instead of wheels can cope with large steps to some extent. However, the caterpillar type bogie is originally electric and cannot be manually driven, and the running load is large. There were also problems such as heavy weight. Since the carriage is required to have the ability to cut along the curve, it was required to respond.

The inventors adopted the track roll mechanism described in Patent Document 1 as the running mechanism of the carriage in order to solve the above-mentioned problems in the carriage, thereby reducing the running load and allowing it to run over large steps and along curves. We manufactured a truck roll type carrier that can easily run and even turn on the spot, can run quietly regardless of the road surface condition, and has the characteristics of a small body weight, and filed an application for this technology. patented. The technology described in Patent Literature 2 is the carrier vehicle.

The track roll type carriage disclosed in Patent Document 2 includes a belt that holds, at regular intervals, a plurality of elements that are arranged on fixed rails and support a plurality of rollers. This belt is made of cloth, and the element is fixed to the belt by sandwiching the belt between a resin element that supports the roller and a plate made of rubber or the like that contacts the ground. Since the carriage is left unattended after work in the external environment, the fabric belt is prone to deterioration due to moisture, dirt, etc., and failures such as breaking due to overload during movement or falling off of the elements fixed to the belt. may occur. Regarding the repair of the carriage in such a case, it is difficult to replace only the belt because many elements are attached. The problem was that it was difficult.

A first embodiment of the present invention will be described below with reference to FIGS. 1 to 4. FIG.
First, the configuration of this embodiment will be described.
A track roll type carrier 10 comprising a traveling unit 20, a carrier unit 30, and a support structure 40 connecting them. a frame 3 for holding the annular rail 2 in shape and mounting a support structure 40 thereon; a plurality of elements 4 arranged on the rail 2 for supporting a plurality of rollers 7; A pair of left and right track rolls 1 made up of belts 5 held at regular intervals is provided. A handle 8 is provided on the rear end side with respect to the traveling direction, and the belt 5 is constructed by assembling belt units 5u divided for each element 4. As shown in FIG.

The belt unit 5u has a plateau-shaped ground contact portion 5a with a flat upper surface 5d having two through holes 5g for inserting and fixing two protrusions 4a projecting from the element 4, and one end portion of the ground contact portion 5a. A belt main body portion 5b having a plurality of holes 5i, and an end portion 5f of the belt main body portion 5b on the side opposite to the ground contact portion 5a. Each belt unit 5u is composed of a flat portion 5c having two through holes 5h for insertion and fixing. The projections 4a of the elements are inserted and connected to the through holes 5g and 5h of the grounding portion 5a and the flat portion 5c to form two sets of continuous belts 5, and the elements 4 are arranged in each ring. They are arranged on the rail 2 at regular intervals.

The carriage portion 30 is composed of the pipe 6, and the support structure 40 is predetermined connecting fittings 9a and 9b. The annular rail 2 has a flat cross-sectional shape.

The element 4 supports the roller 7, and has the same configuration as that described in Patent Document 2.

Functions and effects of the carriage 10 of the present embodiment will be described.
In the configuration of Patent Document 2, the belt 5 is made of cloth, and is sandwiched between the element 4 and the plate to fix the element 4 to the belt 5 . When the carriage is used outdoors or in a factory, moisture and dirt may adhere to the belt 5, and if left as it is, the belt 5 may deteriorate and break due to impact during travel. . In this case, repair was very difficult. Similarly, the element 4 may fall off due to impact during running, and in this case, it is not easy to reattach the element 4 to the belt 5, and the repair is also difficult, requiring the entire track roll to be replaced.

In this embodiment, the belt 5 is assembled by the belt unit 5u, so that the trouble can be easily repaired. Since the belt unit 5u is made of resin, it is not significantly deteriorated by moisture, dirt, or the like. A plurality of holes 5i provided in the belt unit 5u are for improving the flexibility of the belt unit 5u made of resin. Even if the joint part of the belt unit 5u comes off and the belt unit 5u is damaged due to an impact during running, or if the element 4 falls off, the belt unit 5u and the element 4 can be easily repaired by partially reattaching the new belt unit 5u and the element 4.例文帳に追加be able to.

By constructing the carriage part 30 with the pipe 6 including the handle 8 and using the predetermined connecting fittings 9a and 9b as the support structure 40, the structure becomes simpler than the structure of Patent Document 2, and the manufacturing cost is reduced. Significant reduction is possible.

The reason why the circular rail 2 has a flat structure is that the configuration of Patent Document 2 applies the grass ski technology as a traveling mechanism for a carriage. Because the lateral load applied to the track roll during running is small, the roller 7 does not drop off from the rail 2 even if the cross section of the rail 2 is made flat by eliminating the curved shape at both ends. This structural change enables significant cost reduction in manufacturing and assembling the annular rail 2 .

Next, a second embodiment of the invention will be described.
First, the configuration of this embodiment will be described.
As shown in FIGS. 5 to 7, the belt unit 5v in the track roll 1a includes a substantially rectangular parallelepiped rubber plate 5w having two through holes 5k corresponding to the two locking holes 4d provided in the element 4b. , a connection portion 5z that spans two adjacent elements 4b is provided at both ends, and an intermediate portion 5y is constituted by a plate 5n having a plurality of holes 5m. has two through-holes 5j corresponding to the two through-holes 5k of the rubber plate 5w and another two through-holes 5j corresponding to the two projections 4c provided on the element 4b. Over the entire length of each annular rail 2 of the set, each plate 5n is arranged so that the connecting portions 5z at both ends overlap the adjacent elements 4b, and the projections 4c of the elements 4b are inserted into the respective through holes 5j of the connecting portions 5z. Each rubber plate 5w is fixed to each element 4b by a predetermined insertion part (not shown) through each through-hole 5j while sandwiching the connecting portion 5z of each plate 5n. A set of belts 5 is constructed, and elements 4b are arranged on each annular rail 2 at regular intervals.

In this embodiment, as in the first embodiment, it is easy to repair the belt 5 when it is torn due to impact during running, and when the element 4 falls off, it can be easily repaired. Since the belt unit 5v is made of resin, it does not deteriorate significantly due to moisture, dirt, etc., and the flexibility is improved by the plurality of holes 5j.
Even if the belt unit 5v is damaged due to the disconnection of the belt unit 5v due to impact during running, or if the element 4b falls off, the belt unit 5v and the element 4b can be easily repaired by partially reattaching the new belt unit 5v and the element 4b. be able to.
