Abstract
The utility model discloses a counterweight loading and unloading mechanism of a crane, which comprises a turntable rear section (11), a counterweight lifting oil cylinder (1), a horizontal locking pin (4), a lifting base (6) and a standing plate (7). The counterweight lifting oil cylinder (1) and the horizontal locking pin (4) are arranged on the turntable rear section (11); the lifting base (6) is arranged on a counterweight base (8); the turntable rear section (11) is provided with a positioning sleeve (3) which corresponds to the counterweight lifting oil cylinder (1) and the lifting base (6); and an adjustable retaining bolt (2) is arranged on the turntable rear section (11) and corresponds to the upper plane of the standing plate (7). The utility model can maintain the relative heights of the working position of the counterweight and the position of the horizontal locking pin all the time; the counterweight position in the vertical direction is fundamentally fixed; the shaking quantity of the lifting cylinder on the counterweight base in the horizontal direction is controlled within a certain range; and the utility model in particular belongs to the counterweight loading and unloading mechanism of the vehicle crane.
Description
Technical field
The utility model relates to a kind of hoisting crane moving counterweight handing device, and particularly relating to a kind ofly has strong impact resistance, can regulate the counterweight handing device of counterweight lift stroke.
Background technology
In the counterweight self-loading and unloading system that multiple counterweight weight combinations pattern is arranged, counterweight elevating ram and Horizontal lock rationed marketing are installed on the turntable back segment, the counterweight base is provided with upgrade block and riser, the upgrade block external diameter has certain tapering and is provided with and the cooresponding lifting mouth of the piston rod of counterweight elevating ram, riser is provided with and the cooresponding horizontal lock of Horizontal lock rationed marketing hole, if adopted the Horizontal lock rationed marketing to guarantee the safety of system, then the relative position of stop pin and lock hole must be controlled within the specific limits when counterweight rises to control position.Simultaneously, when counterweight is worked, should on level, vertical direction, give the certain amount of restraint of counterweight, prevent that it from rocking.
The utility model content
It is constant that the position that technical problem to be solved in the utility model provides a kind of control position that makes counterweight and Horizontal lock rationed marketing remains relative height, and in the vertical direction balance position basic fixed makes the enhancing tube rolling momentum in the horizontal direction on the counterweight base be controlled at the interior car hosit counterweight handing device of certain limit.
In order to solve the problems of the technologies described above, the hoisting crane that the utility model provides counterweight handing device, comprise the turntable back segment, be installed in counterweight elevating ram and Horizontal lock rationed marketing on the turntable back segment, and upgrade block on the counterweight base and riser, on described turntable back segment, be provided with and described counterweight elevating ram and the cooresponding locating bush of upgrade block, be provided with on the described turntable back segment with described riser on the cooresponding adjustable stopper bolt in plane.
Adopt the car hosit counterweight handing device of technique scheme, when first debugging, it is certain more than needed to add that by the setting to the screw rod overhang of adjustable stopper bolt counterweight elevating ram stroke stays, the counterweight in the vertical direction can accurately be located and stop, after counterweight is installed to control position, counterweight elevating ram, locating bush retrain jointly to the counterweight base, and counterweight activity in the horizontal direction is controlled in the very little scope.
The utility model counterweight handing device mainly contains following effect:
After counterweight was installed to control position, in the vertical direction can accurately be located and stop, on the horizontal direction counterweight is had than strong constraint.
In sum, it is constant that the utility model is that the position of a kind of control position that makes counterweight and Horizontal lock rationed marketing remains relative height, and in the vertical direction balance position basic fixed makes the enhancing tube rolling momentum in the horizontal direction on the counterweight base be controlled at the interior car hosit counterweight handing device of certain limit.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is the scheme drawing of the utility model counterweight handing device.
The specific embodiment
Referring to accompanying drawing, counterweight elevating ram 1 and Horizontal lock rationed marketing 4 are installed on turntable back segment 11, counterweight base 8 is provided with upgrade block 6 and riser 7, upgrade block 6 external diameters have certain tapering and are provided with and the cooresponding lifting mouth 10 of the piston rod of counterweight elevating ram 1, riser 7 is provided with and Horizontal lock rationed marketing 4 cooresponding horizontal lock holes 5, on turntable back segment 11, be provided with and counterweight elevating ram 1 and upgrade block 6 cooresponding locating bushs 3, be provided with on the turntable back segment 11 with riser 7 on the cooresponding adjustable stopper bolt 2 in plane.
As shown in drawings, realize the combination of Different Weight by the stack of combined counterbalance 9, upgrade block 6 and riser 7 are an integral body with counterweight base 8, the external diameter of its cylindrical enhancing tube 6 has certain tapering, have the lock hole 5 that horizontal lock mechanism uses on its riser 7, the lifting mouth 10 of enhancing tube 6 can guarantee with the relative position in horizontal lock hole 5.After the piston rod head of counterweight elevating ram 1 entered lifting mouth 10, the piston rod of counterweight elevating ram 1 was regained; When Horizontal lock rationed marketing 4 can be inserted horizontal lock hole 5 on the riser 7, counterweight arrives control position, at this moment, the stroke of counterweight elevating ram 1 also has more than needed, adjustable stopper bolt 2 withstands plane on the riser 7, the extension elongation of adjustable stopper bolt 2 is adjustable and accurate location, and at this moment, the piston rod of adjustable stopper bolt 2 and counterweight elevating ram 1 retrains the position of counterweight vertical direction jointly.The tapering part tolerance clearance of the hole of locating bush 3 and enhancing tube 6 external diameters is less, and the control position height that can regulate counterweight among a small circle changes its tolerance clearance, utilizes the enhancing tube 6 of locating bush 3 and external diameter band tapering to give the ballast water square constraint that makes progress.When counterweight is installed,, make counterweight 9 that certain impact resistance be arranged after installing, do not rock by matching design to counterweight elevating ram 1 stroke and adjustable stopper bolt 2.
This mechanism is after first debugging is good, and is or else with regulating, easy to use, reliable.
Claims (1)
1, a kind of hoisting crane counterweight handing device, comprise turntable back segment (11), be installed in counterweight elevating ram (1) and Horizontal lock rationed marketing (4) on the turntable back segment (11), and upgrade block (6) on the counterweight base (8) and riser (7), it is characterized in that: on described turntable back segment (11), be provided with and described counterweight elevating ram (1) and the cooresponding locating bush of upgrade block (6) (3), on described turntable back segment (11), be provided with described riser (7) and go up the cooresponding adjustable stopper bolt in plane (2).
