Description

[Detailed description of the invention] Industrial application field The present invention removes harmful debris on the transportation road surface by attaching a cleaner to the side plate of the crawler truck using the existing attachment mounting hole.
The present invention relates to a crawler truck for transporting heavy objects, which reduces running resistance by actively removing gravel and other foreign objects, and allows smooth transport with a small pushing force.

Conventional technology and its problems Conventionally, as a crawler truck for transporting heavy objects utilizing the principle of rollers, which are used by inserting the required number of rollers into the bottom of the heavy object, a top plate a as shown in FIGS. 5 and 6 has been used. A crawler consisting of an endless roller chain in which a number of rollers d are connected in an annular manner by pins e and link plates f is surrounded and held on the outer periphery of a center plate c spanning between a pair of side plates b and b vertically disposed opposite to each other. There is a device in which a heavy object can be easily transported with a small pushing force by rotating and revolving a large number of rollers.

However, although such conventional crawler carts for conveying heavy objects can fully demonstrate their functions on flat conveyance roads, they cannot be used on rough conveyance roads where dirt, sand, and other foreign objects are scattered. Sand, foreign objects, etc. not only become obstacles to conveyance and require extra conveyance force, but also these obstacles get caught inside the crawler truck and accumulate, obstructing the rotation and revolution of the rollers and causing damage to the conveyor. In order to shorten the lifespan of the crawler truck, the inside of the crawler truck must be cleaned frequently, which is troublesome in handling.

Problems to be Solved by the Invention The problems to be solved by the invention, that is, the purpose of the invention is to eliminate the drawbacks of the prior art. To provide a crawler truck with a cleaner that is capable of smoothly transporting heavy objects, is easy to handle, and is durable.

Means for Solving the Problems The present invention has the following structure in order to achieve the above objects. That is, the present invention provides a crawler truck having an attachment mounting hole at the end of the side plate, in which the end surface of the side plate is used as a stopper between a pair of support plates and a restraining plate facing the pair of support plates. The present invention is characterized in that the cleaner member is detachably held, and a supporting pin provided on the support plate is loosely fitted into the attachment mounting hole.

Note that the crawler truck to which the cleaner member is attached is one in which a crawler consisting of an endless roller chain is held around the outer periphery of a center plate that spans between a pair of side plates that are vertically disposed opposite to a top plate. Any other crawler truck may be used as long as it can fully exhibit the functions of the invented crawler truck with cleaner. Further, the side cross-sectional shape of the support plate is preferably an inverted L-shape, but any shape may be adopted as long as it does not hinder the rotation of the crawler included in the crawler truck. The shape of the cleaner member may be any shape that allows the crawler truck to run smoothly while removing dust, sand, foreign matter, etc., that is, a shape that can cover the front surface of the crawler truck in the traveling direction.

Further, as the means for gripping the cleaner member on the pair of support plates and the one restraining plate, screwing means using bolts, nuts, screws, etc. is preferable in consideration of detachable handling.

Effects Since the present invention has the above-mentioned configuration, it has the following effects.

a) Smooth running of the crawler truck is maintained by loosely fitting a support pin provided with a support plate that grips the cleaner member with the end face of the side plate as a stopper into the attachment mounting hole of the side plate of the crawler truck. It has an adjustment function that can control the contact state between the conveyance path surface and the cleaner member to the extent possible.

(b) Since the cleaner member attached to the crawler truck can only rotate inwardly around the loosely fitted support pin by the end face of the side plate, and is free to rotate outward, the cleaner member attached to the front of the crawler truck This allows the foreign matter in front of the vehicle to be completely removed.

Embodiment FIGS. 1 to 4 show an embodiment of a crawler truck with a cleaner according to the present invention, in which FIG. 1 is a side view thereof, and FIG. 2 is a front view of FIG. 1.
FIG. 3 is a perspective view of the assembled cleaner member, and FIG. 4 is a bottom view of FIG. 3.

First, the crawler truck with a cleaner of this embodiment as shown in FIG. A cleaner member 3 is attached using the hole 2, and the attachment structure thereof will be explained in detail below.

As shown in FIG. 3, the cleaner member 3 has an inverted L
A screwing means 6 using a bolt or a nut is held between a pair of support plates 4, 4 having a letter-shaped side cross-sectional shape and a restraining plate 5 facing the pair of support plates 4, 4.
Fix by. Cleaner member 3 and holding plate 5
The width of the side plate is approximately the same as the distance between the pair of side plates. Then, the supporting pins 7, 7 integrally formed on the side ends of the pair of support plates 4, 4, respectively, are rotated into the attachment mounting holes 2, 2 of the side plate 1 of the crawler truck, as shown in FIGS. It can be fitted freely.

The method for attaching the cleaner member 3 and the like to the attachment attachment hole 2, that is, the order of attachment is as follows: After loosely fitting the support pin 7, which is integrally formed with the support plate 4, into the attachment attachment hole 2, the pair of support plates 4, 4 are attached.
The cleaner member 3 is gripped and fixed between the holding plate 5 and the holding plate 5 by screwing means 6, and the removal order is the reverse of the above-mentioned installation order.

The thus-obtained crawler truck with cleaner of this example can smoothly transport heavy objects even if the transport direction is forward or backward, even if the transport path is in a bad condition and is littered with dust, sand, foreign matter, etc. It was hot.

Effects Since the present invention has the above-mentioned configuration and operation, it has the following effects.

By using the attachment mounting holes in the side plates of the crawler truck, the cleaner member can be attached via a pair of support plates with support pins and a holding plate, making it easy to attach and detach the cleaner member. None can be obtained.

By holding the cleaner member through a pair of support plates and a holding plate, it is possible to securely attach the cleaner member regardless of its cleaning characteristics, such as hard or soft, so that it can be mounted securely regardless of the cleaning characteristics of the conveyor. By appropriately selecting a cleaner member according to the situation, it is possible to remove any foreign matter from the conveyance path surface where the foreign matter is scattered, thereby achieving smooth conveyance.

By loosely fitting a support pin provided with a support plate for gripping the cleaner member into the attachment mounting hole, the contact state of the cleaner member with the conveyance road surface can be adjusted to such an extent that the crawler truck can run smoothly. Dust, sand, foreign matter, etc. on the conveyance road surface can be efficiently removed.

The cleaner member attached to the front of the crawler truck can completely remove foreign objects in front of the crawler, and the cleaner member attached to the rear rotates freely to the outside, so it does not create running resistance and reduces pushing force. can be measured.

As described above, the crawler truck equipped with a cleaner of the present invention can smoothly transport heavy objects even on rough transport roads strewn with dust, sand, foreign matter, etc., and is easy to handle and durable. It has excellent practical effects.
