Description
Technical Field
The utility model relates to a jacking equipment technical field especially relates to a counter weight is from hoisting device for hoist.
Background
The conventional counterweight self-lifting device for the crane lifts a counterweight to a working position by using a vertical oil cylinder or a mode of the vertical oil cylinder, a pulley and a steel wire rope. However, both of the two methods can only lift the counterweight in the vertical direction, but cannot change the amplitude of the counterweight, and when the counterweight is lifted, the counterweight can only be positioned right below the vertical oil cylinder, so that the requirement on the initial placement position of the counterweight in the horizontal plane is high.
Disclosure of Invention
For solving present counter weight from hoisting device for hoist and can not change the range of counter weight, and require higher technical problem to the initial locating position of counter weight in the horizontal plane, the utility model provides a counter weight is from hoisting device for hoist.
In order to solve the technical problem, the utility model discloses a technical scheme is:
the utility model provides a counter weight is from hoisting device for hoist, its includes that pendulum rod, counter weight are from lifting cylinder, regulation pole, counter weight tray frame and counter weight tray, wherein: the pendulum rod, the counter weight is from promoting the hydro-cylinder, adjust each two of pole and counter weight tray frame and be located hoist revolving stage both sides respectively, the counter weight is articulated with the hoist revolving stage from the one end of promoting the hydro-cylinder, the counter weight is from the tail connection of the other end of promoting the hydro-cylinder through round pin axle and pendulum rod, the head and the hoist revolving stage of pendulum rod are articulated, the afterbody of pendulum rod is provided with U type groove, the upper portion of adjusting the pole is provided with connecting pin axle, connecting pin axle card is gone into in the U type groove, the lower part of adjusting the pole is articulated with the upper portion of counter weight tray frame, the lower part of counter weight tray frame that is located hoist.
The utility model has the advantages that:
the counterweight can be lifted to different working positions by the extension and retraction of the counterweight self-lifting oil cylinder; the balance weight can be positioned at different initial positions in a small range through the adjusting rod, and the amplitude of the balance weight can be changed within a certain range. Through the matching of the balance weight self-lifting oil cylinder, the swing rod and the adjusting rod, the self-lifting requirement of the balance weight in the horizontal direction and the vertical direction is met, and the requirement on the initial placing position of the balance weight in the horizontal plane is lowered.

Fig. 2 is a schematic view of a first initial position of the counterweight.
Fig. 3 is a schematic view of a second initial position of the counterweight.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, the counterweight self-lifting device for a crane in this embodiment includes a swing rod 1, a counterweight self-lifting cylinder 2, an adjusting rod 3, a counterweight tray frame 4, and a counterweight tray 5, wherein: pendulum rod 1, the counter weight is from promoting hydro-cylinder 2, adjust the pole 3 and the weight tray frame 4 respectively two and be located 7 both sides of crane revolving stage respectively, the counter weight is articulated with crane revolving stage 7 from the one end of promoting hydro-cylinder 2, the counter weight is from the other end of promoting hydro-cylinder 2 through the end connection of round pin axle with pendulum rod 1, the head of pendulum rod 1 is articulated with crane revolving stage 7, the afterbody of pendulum rod 1 is provided with U type groove, the upper portion of adjusting pole 3 is provided with connecting pin axle, connecting pin axle card is gone into in the U type groove, the lower part of adjusting pole 3 is articulated with the upper portion of weight tray frame 4, the lower part of weight tray frame 4 that is located crane revolving stage 7 both sides is connected with the both sides of weight tray.
The utility model discloses when using, the control counter weight from the length that lift cylinder 2 stretches out and with the contained angle of horizontal plane, can promote the operating position with counter weight 6 by initial position, simultaneously, adjust pole 3 and can make counter weight 6 be in the different initial position of miniaturation around the rotatory certain angle of pendulum rod 1, these initial positions have satisfied the requirement from promoting of counter weight 6. Fig. 2 and fig. 3 are schematic diagrams of the initial position change of the counterweight 6 when the adjusting rod 3 rotates around the swing rod 1 by different angles.
The utility model provides high counter weight 6 from the maneuverability that promotes has also changed counter weight 6's range at counter weight 6 from the in-process that promotes simultaneously to increased counter weight 6's moment, reduced counter weight 6's total mass, practiced thrift the cost that promotes the counter weight, had advantages such as simple structure and the installation of being convenient for. The utility model discloses can install at the afterbody of hoist revolving stage 7, occupation space is less.
It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
