In the case of a vibrating roller that is operated by a worker while walking, a guide rod protruding from the rear of the vibrating roller body is used as a handhold for the worker to determine the running direction of the vibrating roller, and an operation device provided at the end of the guide rod is used as a guide rod. Because a group of levers are used to move forward, backward, stop, and other necessary operations, the guide rod end is located close to the worker's torso for convenient operation. When using this, there is a danger that the worker may get caught between an obstacle and the guide rod when reversing and have their torso pressed, or even if there is no obstacle, they may be pushed down by the guide rod due to inadvertence and be guided by the rollers. This has led to fatal accidents in recent years.

However, in these emergency stop devices, a series of emergency stop devices consisting of a detection member and a connecting member to the clutch and brake is separate from the normal clutch and brake control device and is an independent mechanism. , vehicle (
In this invention, the structure of the vibrating roller itself is complicated, which causes production and cost problems, and it is not easy to modify existing vehicles to include an emergency stop device, and from a maintenance standpoint, the emergency stop device is unique. As a result, for safety reasons, it is necessary for workers to constantly check whether the emergency stop device is operating normally or to install a mechanism to detect abnormalities in the emergency stop device. There was the inconvenience of having to install it separately.

The purpose of this invention is to eliminate the drawbacks of the conventional device as described above.It is located at the rear end of the vehicle and is connected to a valve for switching forward, stop, and reverse rotation of the hydraulic motor for driving the vehicle. When the travel control lever is in the reverse position, the end of the grip is stretched backwards from the base of the control lever by pushing down and pulling down the vehicle in the longitudinal direction of the vehicle. When the traveling control lever is in the stop position, the grip end is bent backward so that it is on the same line as the end surface of the operating lever pedestal, and the operating lever is inserted through the top plate of the operating lever pedestal. A guide groove is provided to regulate the direction of the vibration force of the operating lever, and this guide groove allows the operating lever to vibrate in the front-rear direction, and is shaped like a crank to be locked to the stepped portion of the crank when the operating lever is at the stop position. The present invention constitutes an emergency stop device for a vibrating roller characterized by the following, and instead of conventionally requiring two systems: an emergency stop device and a normal control device, the structure is such that the normal control device also serves as an emergency stop device at the same time.
It is a single system system, and is especially useful for vibrating rollers driven by hydraulic motors (Hydrostatic drive), which can easily control forward, stop, and reverse in one movement without using a clutch or brake. This makes it possible to provide an emergency stop device.

As shown in FIG. 3, this travel control lever 5 is supported by a shaft 7 on a pedestal 6 so as to vibrate in the longitudinal direction of the vehicle. By connecting the lever 9 of the stop/reverse switching valve with the rod 8, pushing the travel control lever 5 forward moves the vehicle forward to a neutral position to stop the vehicle, and pulling it backwards moves the vehicle backwards. It is in charge of the

Furthermore, the travel control lever 5 holds the grip part 5' in such a way that when it is in the reverse position, the end of the grip part 5' projects backward from the operation lever pedestal 6 - when it is in the R position in FIG. An emergency stop device is constructed by bending the grip portion 5' rearward so that the end of the grip portion 5' is located on the same line as the end surface of the operating lever pedestal 6 - position N in FIG.

That is, normally, the operator grips and uses the grip part 5' as a traveling control lever, but when the vehicle is moving backwards, the operator can use the grip part 5' to handle the vibration roller 1 (specifically, the control lever provided at the 4th end of the guide rod). If the lever is about to get caught between the lever and the pedestal 6), or if it is about to be pushed down, the grip part 5' end bends and protrudes rearward, so the operator must first perform the driving operation. The lever 5 comes into contact, and as the vehicle moves backward, the travel control lever 5 is pushed up to a stop position where the end of the grip portion 5' and the end surface of the control lever pedestal 6 are located on the same line, and the vehicle stops, acting as an emergency stop device. It is something to do.

Furthermore, as shown in FIG.
The guide groove 6' of the upper plate is made into a rank shape so that it is locked to the step C when the travel control lever 5 is in the stop position, and when switching from the stop position to the forward position during operation, tilt the lever once to the side and press the crank. It is structured to release the lock at the part, and prevents the traveling operation lever 5 from inadvertently passing through the stop position and switching to the forward position during an emergency stop, thereby causing a secondary accident.

Located at the rear end of the vehicle, the hydraulic motor for driving the vehicle rotates in the forward direction.
When the travel control lever is in the reverse position, the grip part of the travel control lever, which controls forward, stop, and reverse operation of the vehicle, is connected to the stop/reverse switching valve by pushing down and pulling down in the longitudinal direction of the vehicle. When the traveling control lever is in the stop position, the end of the gripping portion is bent backward so that it is located on the same line as the end surface of the operating lever 1 pedestal, and the end of the gripping portion is bent backward so that the end of the gripping portion extends backward from the operating lever 1 pedestal. The upper plate of the pedestal is provided with a guide groove that regulates the direction of the vibration force of the operating lever by inserting the operating lever therethrough, and this guide groove enables the operating lever to move back and forth in the w1 direction.
An emergency stop device for a vibrating roller, characterized in that the operating lever has a crank shape that locks onto a stepped portion of the crank when the operating lever is at the stop position.
