Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example one

With reference to the attached drawing 1, the forklift capable of realizing forward and backward movement of the balancing weight comprises a forklift body 1 and the balancing weight 2, wherein the balancing weight 2 is arranged at the tail part of the forklift body 1, a cab 4 is arranged on the forklift body 1, a connecting piece 3 is arranged between the forklift body 1 and the balancing weight 2, one end of the connecting piece 3 is connected to the balancing weight 2, and the other end of the connecting piece 3 is connected to a hydraulic motor 7; be equipped with operating valve 5 in the driver's cabin 4 of fork truck body 1, still be equipped with the fuel feeding pipe 6 of being connected with operating valve 5 on the fork truck body 1, hydraulic motor 7 drive connecting piece 3 forward, reverse linear motion for balancing weight 2 is towards the direction motion of being close to or keeping away from fork truck body 1.

The hydraulic motor 7 is fixed at the tail part of the forklift body 1, and the oil supply pipe 6 penetrates through the cab 4 and then is connected with an oil tank 10 on the forklift body 1.

When the balancing weight 2 of the utility model is installed, the balancing weight is firstly connected to the tail part of the forklift body 1 through one end of the connecting piece 3, and then connected to the balancing weight 2 through the other end of the connecting piece 3; then, a driving device for driving the connecting piece 3 to move back and forth is installed, and specifically comprises an oil supply pipe 6, a hydraulic motor 7 and an operating valve 5, wherein the oil supply pipe 6 is fixed on the forklift body 1 (specifically, on the frame of the forklift body 1) through existing fixing pieces such as hoops, one end of the oil supply pipe 6 is connected with an oil tank 10 (the oil tank 10 inherent on the forklift body 1) on the forklift body 1, the other end of the oil supply pipe is connected with the operating valve 5, and the operating valve 5 is set as a hydraulic valve, so that oil is supplied to the operating valve 5; install hydraulic motor 7 at the afterbody of fork truck body 1 and be close to the position of connecting piece 3, and make hydraulic motor 7's output and the one end of connecting piece 3 be connected to drive connecting piece 3 at hydraulic motor 7 pivoted in-process and realize the seesaw, reach the purpose that makes the 2 back-and-forth movements of balancing weight. In the process of installation, guide pillar 8 and guide pin bushing 9 can be side by side and the interval sets up to two or more to guarantee that balancing weight 2 realizes linear motion.

During specific work, the method is divided into two working states:

1) when a forklift is used for carrying a heavy object, goods to be carried are placed at the front part of the forklift body 1 according to the prior art, then a forklift driver starts an operation valve 5 in a cab 4 to supply oil to a hydraulic motor 7, starts the hydraulic motor 7, and rotates the hydraulic motor under the driving of a hydraulic pump, so that a connecting piece 3 is driven to move linearly, and a balancing weight 2 is driven to move by the connecting piece; because the connecting piece 3 is the back-and-forth movement under the drive of hydraulic motor 7, so can change the distance between balancing weight 2 and the fork truck body 1, according to the relation between the power multiplication arm of force to reach the purpose of balanced fork truck body 1.

2) When carrying light heavy object, the working process is opposite to the heavy object carrying process, so that the counter weight block moves towards the direction close to the forklift body 1 under the driving of the hydraulic motor 7, and the purpose of balancing the forklift body 1 is achieved.

The connecting piece 3 is in a straight rod shape and is more than or equal to one.

The connecting piece 3 is a screw rod 31, and a nut 32 matched with the screw rod 31 is arranged on the screw rod 31; the output of hydraulic motor 7 is connected to the one end of lead screw 31, and the other end of lead screw 31 is connected on balancing weight 2.

The screw rod 31 can realize linear motion in the rotating process, so the connecting piece 3 for realizing the forward and backward movement of the balancing weight is arranged into a screw rod 31 structure and is driven by the hydraulic motor 7; in order to work better with the hydraulic motor 7, an internal thread adapted to the threaded spindle 31 is provided on the counterweight 2, so that the two are screwed together.

According to the weight difference of balancing weight 2 to and the difference of fork truck model, can set up lead screw 31 into more than or equal to one, and the interval spiro union is on balancing weight 2, thereby makes balancing weight 2 stably set up on fork truck body 1.

The balancing weight 2 is also provided with a guide post 8 and a guide sleeve 9, so that the balancing weight 2 can be guided to move linearly under the driving of the screw 31.

In order to promote the balancing weight 2 to move according to the linear motion track, a guide pillar 8 and a guide sleeve 9 are arranged in the device, the guide sleeve 9 is located in the inner position of the balancing weight 2, and the balancing weight 2 can be guaranteed to move linearly under the driving of the hydraulic motor 7.

Guide pillar 8 and guide pin bushing 9 connect in order, and the tip end-to-end connection of guide pillar 8 and guide pin bushing 9, inside balancing weight 2 was located to the one end of guide pin bushing 9.

In order to make the guide effect of the guide pillar 8 and the guide sleeve 9 stronger, when the device is manufactured in a specific mode, the guide pillar 8 and the guide sleeve 9 can be set to be more than or equal to one.

Example two

Connecting piece 3 establishes to hydraulic cylinder, and hydraulic cylinder one end is connected on fork truck body 1, and the other end is connected on balancing weight 2, and hydraulic cylinder supplies oil through supply line 6.

When concrete implementation, accessible hydraulic cylinder's motion drives 2 seesaws of balancing weight to reach the purpose of adjusting the interval between balancing weight 2 and the fork truck body 1, and then make fork truck body 1 keep balance. At its in-process of work, supply oil to it through supply oil pipe 6, to the balancing weight of different weight, one or two oil tanks 10 of alternative installation to make hydraulic cylinder can drive 2 linear motion of balancing weight smoothly.

Because the inherent hydraulic system such as motor, hydraulic pump and control flap etc. on the fork truck body 1, so in this device, only need add lead screw 31, hydraulic motor 7 or hydraulic cylinder that promote balancing weight 2 and remove can.
