Description

[Detailed description of the invention] (a) Industrial application field The present invention is used in the field of controlling the pushing device of a garbage truck with an operating lever.

(b) Conventional technology In conventional garbage trucks, the garbage pushing device is controlled by an operating lever, and furthermore, a regulating member is used to stop the pushing device in an emergency or to lock the operating lever in the stop position while the vehicle is running. It is located close to the operating lever. Also, a separate lever was provided for operating the governor control to make the engine run at high speed when the pushing device was in operation, and for returning the engine to an idling state when the pushing device was stopped.

(C) Problems to be solved by the invention In the above configuration, the regulation member and the governor control lever must be operated separately, so there are cases where the vehicle is driven while forgetting to operate one of them.

Therefore, if you forget to operate the former, the operating lever will switch due to vibrations while driving, causing the engine to stop or the pushing device to operate, and in the latter case, the engine will remain at high speed and the engine will not change. As a result, the chain transmission will not switch smoothly, and there is also the risk of damaging the gear.

(d) Means for Solving the Problems The present invention solves the above-mentioned drawbacks, and is a garbage truck that pushes garbage into a container using a pushing device in the packer connected to the rear of the container. is provided with an operating lever for controlling the pushing device, a regulating member is provided at a position close to the operating lever, the regulating member is movable in a direction perpendicular to the moving direction of the operating lever, and the regulating member includes an operating lever. A lock release part that can be operated to any position, a guide part that guides the operation lever from any position of the lock release part to a neutral position, and a lock part that locks the operation lever in the neutral position are provided, and the lock release part is further restricted. The member has a mechanism that allows the engine to move when the regulating member is operated in a direction that places the operating lever in the locking section, when the engine side governor control is placed in an idling state, and when the regulating member is operated in a direction that places the operating lever in the locking section. This invention relates to a safety device for an operating device in a garbage truck, which is characterized by being equipped with a transmission means for setting a side governor control in a high rotation state.

(e) Example An example will be described below with reference to the drawings. 1 is a garbage truck, the garbage truck 1 has a container 3 for storing garbage mounted on a vehicle body 2, and has a pushing device 4 at the rear of the container 3. Patsuka 5 is connected.

Further, the pushing device 4 is driven by the running engine 6 of the garbage truck 1, and since a particularly large load is generated in the operation of the pushing device 4, a governor control 7 is provided to keep the engine 6 in a high rotation state. It is being

Operating levers 8, 8 for controlling the pushing device 4 are provided on the side surface of the packer 5, and are pivotally supported by a bracket 9 so as to be swingable up and down.

Reference numeral 10 denotes a regulating plate that is a regulating member that guides the operating levers 8, 8 from any position to the neutral position, that is, the stopping position of the pushing device 4, and locks it in the neutral position. The arms 12 can be swung in a direction perpendicular to the vertical direction of the operating levers 8, 8.

The regulation plate 10 is provided with a hole 13 through which the operating levers 8, 8 pass, and the hole 13 has a locking portion 14 for locking the operating levers 8, 8 in a neutral position;
It is composed of a tapered guide part 15 that guides the operating levers 8, 8 to the neutral position, and a lock release part 16 that allows the operating lever to be operated to any position.When the regulating plate 10 is pushed forward in FIG. The operating levers 8, 8 are locked in a neutral position by a lock portion 14, and when pulled rearward, the operating levers are unlocked and can be operated to any desired position.

Reference numeral 17 denotes a handle for swinging the regulation plate 10, and the handle 17 is fixed to the arm 12.

One end of a push-pull wire 18 serving as a transmission means is connected to the handle 17, and the other end of the push-pull wire 18 is connected to an arm 19 of the governor control 7 through the top and front of the container 3.
Using the handle 17, pull the regulation plate 10 to position the operating levers 8, 8 in the lock release part 16 (third
(Fig.), the arm 19 of the governor control 7 swings via the control wire 18 to make the engine 6 rotate at a high speed, and the handle 17 pushes the regulation plate 10 to lock the operating levers 8, 8 in the neutral position. (FIG. 4), the arm 19 is returned via the control wire 18, and the engine 6 is placed in an idling state.

Although the push-pull wire is attached to the handle in the embodiment, it is also possible to attach it directly to the regulating plate.

(f) Effect of the invention As described above, the invention connects the governor control to the regulating member that can control the operating lever of the pushing device to the neutral position by means of a transmission means, and makes the engine rotate at high speed when the operating lever is operable. Since the engine returns to idling when the control lever is locked in the neutral position, the governor control can be operated at the same time by locking or unlocking the control lever, eliminating the possibility of operating mistakes as in the past. This eliminates all fuel costs and reduces labor costs for fuel.

In addition, the regulating member is provided with a guide section that guides the operating lever to the neutral position, so that no matter which position the operating lever is in, the regulating member is always moved in the same direction. It can be returned to the neutral position and the operation can be performed reliably.
