Referring to fig. 1-2, a balance crane for material handling includes a vertical column 1, a base 2 fixedly connected to a bottom end of the vertical column 1, an air tank 3 fixedly connected to a top end of the vertical column 1, an air pressure motor 4 fixedly mounted to one side of the air tank 3, a pneumatic cylinder 5 fixedly connected to the other side of the air tank 3, a boom 6 movably connected to a top end of the pneumatic cylinder 5, a boom arm 7 movably connected to one end of the boom 6, a connecting rod 8 movably connected to a bottom end of the boom 6, a hook 9 fixedly mounted to a bottom end of the boom arm 7, a balance spring 10 fixedly connected to the other end of the boom 6, a balance piston 11 fixedly connected to a bottom end of the balance spring 10, a piston cylinder 12 movably sleeved to a bottom end of the balance piston 11, a hose 13 fixedly connected to a bottom end of the piston cylinder 12, a suction cup 14 fixedly connected to a bottom end of.
The base 2 is divided into an upper part and a lower part, the upper part of the base can rotate along the vertical axis of the base, the lower part of the base is fixedly connected with the sucker 14, so that when the device lifts materials to be carried, the upper end of the base can rotate freely to transfer the materials to different positions, and the lower end of the base is fixedly connected with the sucker 14, so that the device is closely attracted with the ground in the using process, the device is prevented from overturning when lifted, meanwhile, the base is not required to be dug and cast for fixing, the damage to the ground is reduced, the device can move freely and work at any position of the ground, and the flexibility of the device is improved.
The air pump 15 is started and stopped along with the pneumatic cylinder 5, the pneumatic cylinder 5 is started when materials are moved upwards and lifted, the pneumatic cylinder 5 is closed when weights are placed downwards, when materials are moved upwards and lifted, the suction cup 14 is pumped by the air pump 15, so that a negative pressure state is formed in the suction cup 14, the suction cup 14 is only adsorbed on the ground, the stability of the materials is enhanced, meanwhile, the negative pressure in the suction cup 14 enables the balance piston 11 to move to the bottom end of the piston cylinder 12 and has an adsorption force on the piston cylinder 12, the suction cup 14 and the balance spring 10 simultaneously apply a balance compensation pulling force on the large arm 6, a lubricating agent is coated between the balance piston 11 and the piston cylinder 12, the sliding friction force between the balance piston 11 and the piston cylinder 12 is smaller than the force for stretching the balance spring 10, after the negative pressure in the suction cup 14 is formed, the balance piston 12 firstly acts on the piston cylinder 12 to pull the large arm 6 downwards and provide, the balance force is compensated by the elastic force provided by the balance spring 10, so that the self-weight compensation of the balance crane not only depends on the elastic force of the spring, and the problem of large fluctuation of the compensation change of the balance force caused by non-constant elastic force is avoided.
When transferring the material, air pump 15 stop work, big arm 6 tractive balance spring 10 and balanced piston 11 rebound, make cavity volume increase in sucking disc 14 and the piston cylinder 12, inside atmospheric pressure reduces, thereby guarantee that sucking disc 14 still tightly adsorbs in ground, guarantee the stability of whole device, negative pressure in the piston cylinder 12 makes to have one and hinders the power that balance piston 11 rises simultaneously, provide a compensation to balance spring 10 spring balance power, make still to have negative pressure and balance spring 10 elasticity to compensate the dead weight of balanced jib jointly at the in-process of transferring, replace original fixed spring through the spring that moves about and provide balanced compensation power, thereby reduce the influence that the big fluctuation of fixed elasticity size caused.
The use method (working principle) of the invention is as follows:
when the device is used, the device is moved to a proper position, the hoisting arm 7 is lowered to enable the hoisting hook 9 to contact materials to be carried, the balance spring 10 and the balance piston 11 are pulled upwards by the bottom end of the large arm 6 in the falling process of the hoisting arm 7, the sliding friction force between the balance piston 11 and the piston cylinder 12 is smaller than the force of the balance spring 10, the balance piston 11 is pulled upwards, the volume of a cavity in the piston cylinder 12 is increased to reduce the air pressure, so that the sucking disc 14 is tightly adsorbed on the ground, the device is prevented from overturning in work, the ground is not required to be damaged in the fixing process of the base 2, the installation position of the balance crane is conveniently moved and adjusted, after the hoisting hook 9 and the materials are fixed, the materials are pulled upwards through the air box 3, the air pump 15 sucks the sucking disc 14 while the air box 3 works, and the sucking disc 14 is still adsorbed on the ground, meanwhile, the negative pressure in the piston cylinder 12 provides a downward pulling force for the large arm 6, so that the bottom end position of the balance spring 10 is controlled along with the negative pressure in the sucker 14, the negative pressure in the sucker 14 and the floating balance spring 10 simultaneously provide self-weight balance compensation force for the large arm 6, and the problems caused by inconstant elasticity and large variation fluctuation are solved.
