Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an operation handle of a plate compactor used for compacting a road surface in road construction.

[0002]

[Prior art]

 Conventionally, as this type of plate compactor, for example, there is one shown in FIG.

This plate compactor is composed of a compaction plate 1, a vibration generator 2 mounted and fixed on the compaction plate 1, and an engine base 4 fixed on the compaction plate 1 via a vibration-proof rubber 3. The engine 5 mounted and fixed on the engine 5 and the operation handle 6 mounted on the engine base 4 are provided.

The operation handle 6 extends obliquely rearward of the machine body in order to facilitate the operation of the machine body, and pivots to an upright position (a position shown by a chain line in FIG. 5) in consideration of a space for storage. Installed as possible.

Then, by driving the engine 5, the rotational force thereof is transmitted to the vibrating body 2 via the centrifugal clutch 7 and the belt transmission mechanism 8, whereby vibration is generated in the vibrating body 2 and the vibration thereof is generated. Is transmitted to the compaction plate 1. The rolling compaction plate 1 that has been subjected to vibration compacts the road surface, etc. while self-propelled on the road surface. At this time, the operator operates the operation handle 6 to steer or turn the machine body.

[0006]

[Problems to be solved by the device]

 By the way, this type of plate compactor is used for auxiliary work of large rollers, pavement work in narrow places or partial repair pavement work, etc., but especially in connection with the repair pavement work, the existing pavement part and the new pavement part are connected. A strong degree of compaction is required for the work.

Therefore, conventionally, the operator obtains a desired compacted state by pushing down the operation handle 6 so that a force in the road surface rolling direction is applied to the rolling plate 1. However, in this case, Since the front part of the pressure plate 1 floats up and the rear part is rubbed against the road surface, etc., there is a disadvantage that only the rear part of the pressure plate 1 is abraded early.

Further, conventionally, in pavement work in a narrow space, for example, pavement work inside a building, the operation handle 6 becomes an obstacle when the aircraft is turned near a wall, so compaction in every corner is insufficient. In addition, the operation handle 6 interfered with the repair pavement work on the lower surface of the guardrail, etc., and the work could not be performed.

[0009] Furthermore, there is a demand for downsizing of this type of plate compactor so that it can be easily loaded on a light van or the like when it is transferred between construction sites.

Therefore, the present invention has been made in view of the above problems, and it is possible to prevent abrasion of only a part of the compaction plate and also to sufficiently compact the corners of the wall. An object of the present invention is to provide an operating handle for a plate compactor that can reduce the size of the machine body.

[0011]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the invention of claim 1 is to provide a holding member at the center of the upper end of an inverted U-shaped support rod at the rear end of an engine base mounted and fixed on a rolling plate equipped with an oscillating body. The operating handle is attached to this holding member so that it can be expanded and contracted in the longitudinal direction of the machine and can be fixed at the desired position.

According to the invention of claim 2, the holding member is provided so as to be rotatable with respect to the support rod in the longitudinal direction of the machine body within a predetermined range.

[0013]

[Action]

 According to the invention of claim 1, the operation handle is pushed toward the front of the machine body, the operation handle is grasped at the front and rear positions of the holding member, and the pressing force is applied to this so that the force in the road rolling direction is applied to the rolling plate. The compaction force can be increased by bringing the entire rolling plate into pressure contact with the road surface. Therefore, it is possible to prevent only a part of the pressure plate from being worn away.

Further, by removing the operation handle from the machine body and inclining and fixing the support rod diagonally rearward of the machine body, the support rod can be made to have the same height as the machine body, and the lower surface of the guide rail or the like can be tightened. The hardening work can be performed without any trouble.

[0015] Furthermore, by removing the operation handle from the machine body or pushing it in the front direction of the machine body, the machine body can be downsized, and it is possible to easily carry out loading and unloading on a light van or the like.

According to the second aspect of the present invention, in addition to the same action as the first aspect, the operation handle can be rotated forward of the machine body to rotate the machine body. This facilitates compaction work on the walls, etc., and allows compaction in every corner without leaving behind.

[0017]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of a plate compactor according to an embodiment of the present invention.

This plate compactor includes a compaction plate 1, a vibrating body 2 mounted and fixed on the front portion of the compaction plate 1, and a vibration damping rubber 3 mounted on the compaction plate 1 as in the conventional case. It has a fixed engine base 4 and an engine 5 mounted on the engine base 4. By driving the engine 5, its rotational force is transmitted to the vibration body 2 via the centrifugal clutch 7 and the belt transmission mechanism 8. As a result, vibration is generated in the vibrating body 2, and the vibration is transmitted to the pressure roller 1.

Therefore, in this embodiment, a pair of left and right mounting plates 9 are erected on the rear end of the engine base 4, and the open ends of the inverted U-shaped support rod 10 are connected to these mounting plates 9, respectively. A pin 11 is connected so as to be rotatable in the machine front-rear direction. The mounting plate 9 has two fixing pin holes 12 and 13 for positioning and fixing the support rod 10.

These fixing pin holes 12 and 13 are arranged on the rotation path of the support rod 10, and one fixing pin hole 12 extends the support rod 10 obliquely rearward at a predetermined angle with respect to the machine body. The fixing pin hole 13 is provided at a position where the support rod 10 is fixed in a vertical state with respect to the machine body. Then, by inserting a fixing pin (not shown) into the pin hole 14 provided at the lower end portion of the supporting rod 10 or one of the fixing pin holes 12 and 13, the supporting rod 10 is slanted rearward with respect to the machine body. It can be fixed in the extended position or vertical position.

A holding member 15 is fixed to the center of the upper end of the support rod 10 at a predetermined angle, and an operating handle 16 is attached to the holding member 15 so as to be extendable in the longitudinal direction of the machine body.

In this embodiment, the holding member 15 is formed of a hollow pipe material or the like, and the operation handle 16 is slidably inserted in the hollow hole. Further, the holding member 15 is provided with a fastener 17 for fixing the operation handle 16.

Therefore, by inserting the operation handle 16 into the holding member 15 and tightening it with the fastener 17, the operation handle 16 can be fixed at a desired position with respect to the machine body. The operating handle 16 can also be removed from the machine body by loosening it. Incidentally, reference numeral 18 in the drawing denotes a grip made of a rubber member or the like.

In the plate compactor configured as described above, when a strong compaction degree is required such as a connection work between an existing pavement part and a new pavement part, as shown by a chain line in FIG. The operator pushes the handle 16 forward of the machine body, and the operator grips the operation handle 16 at the front and rear positions of the holding member 15, and applies a pressing force to the rolling handle 1 so that a force in the road rolling direction is applied to the rolling plate 1. The compaction force is increased by pressing the entire No. 1 to the road surface. Therefore, it is possible to prevent only the rear portion of the pressure roller plate 1 from being worn away as in the conventional case.

When compacting the lower surface of the guide rail or the like, as shown in FIG. 2, the operation handle 16 is removed from the machine body and the support rod 10 is tilted obliquely rearward and fixed to the machine body. The support rod 10 can be made to have the same height as the entire height of the machine body, which allows the machine body to freely move in and out of the gap between the lower end of the guide rail and the road surface. Therefore, the work of compacting the lower surface of the guide rail or the like can be performed without any trouble.

Further, the operation handle 16 can be reduced in size by removing the operation handle 16 from the machine or pushing it forward of the machine as shown by the chain line in FIG. 1, so that it can be loaded onto a light van or the like when the machine is transferred. The loading and unloading can be done easily.
