Technical Field

The utility model relates to a stranding machine technical field especially relates to a semi-automatic elevating gear.

Background

High-speed stranding machine is when receiving the line fast, there is a lift platform board below the board, convenient and fast goes up and down the drum, however lift platform in present stage is by hydraulic means control platform lift, owing to be that hydraulic means itself has certain height, so the platform carries the drum and still has the take the altitude from ground when reducing to the lower, the place must set up the slope in the platform lower, roll full dish to subaerially through the slope, the security performance is lower when unloading the dish like this, the drum is difficult to control when rolling off, there is certain potential safety hazard.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: in order to overcome the defects in the prior art, the utility model provides a semi-automatic lifting device.

The utility model provides a technical scheme that its technical problem will adopt is: the utility model provides a semi-automatic lifting device, includes frame, tray, lifting unit and counter weight subassembly, the tray is located in the frame with frame edge vertical direction sliding connection, lifting unit includes fixed pulley and counter weight layer board, the fixed pulley is located the frame top with the frame rotates to be connected, around being equipped with on the fixed pulley and connecting the rope, connect rope one end with tray fixed connection, connect the rope other end with counter weight layer board fixed connection, the counter weight subassembly includes balancing weight and counter weight frame, the counter weight erects in counter weight layer board one side, be equipped with the drive on the counter weight frame the balancing weight is close to or keeps away from the drive arrangement of counter weight layer board.

The machine frame is used for bearing a tray and a lifting assembly, the tray is used for bearing a wire coil, the tray is connected with the machine frame in a sliding mode along the vertical direction and is used for being matched with the lifting assembly to drive the wire coil to ascend or descend, and therefore ascending assembly of an empty wire coil on a high-speed wire stranding machine and descending and unloading of a wound full wire coil are achieved; the fixed pulley is used as a fulcrum, when no balancing weight is arranged on the balancing weight supporting plate, the weight of the balancing weight supporting plate is slightly larger than that of the tray and the empty wire coil, and the slow and stable rising of the empty wire coil on the tray under the action of the gravity of the balancing weight supporting plate is ensured; when the counterweight block is arranged on the counterweight support plate, the weight of the counterweight support plate and the counterweight block is slightly less than that of the tray full wire coil, so that the full wire coil on the tray slowly and stably descends under the gravity action of the counterweight support plate and the counterweight block; the counterweight frame is provided with a driving device for adding a counterweight block to the counterweight supporting plate or taking down the counterweight block on the counterweight supporting plate.

Furthermore, in order to add the balancing weight on the balancing weight layer board or take off the balancing weight on the balancing weight layer board, the balancing weight is U-shaped, a plurality of rollers are embedded at the lower end of the balancing weight, a limiting rod matched with a U-shaped groove is vertically arranged on the balancing weight frame, and the driving device comprises an electromagnet arranged on the upper side of the balancing weight frame and an air cylinder arranged on the lower side of the balancing weight frame.

When the counterweight block and the counterweight support plate are at a high position, the electromagnet is electrified to attract the counterweight block from the counterweight support plate to the counterweight frame, and because the counterweight block is heavier, the roller is arranged at the lower end of the counterweight block, so that the friction force is reduced, and the electromagnet is convenient to attract the counterweight block; the counterweight frame is provided with a limiting rod for limiting the position of the counterweight block and preventing the counterweight block from being adsorbed on the electromagnet, and after the U-shaped groove of the counterweight block is contacted with the limiting rod, the counterweight block slides to the bottom of the counterweight frame under the action of self gravity; when the balance weight supporting plate is at a low position, the air cylinder stretches out, and the balance weight block arranged at the bottom of the balance weight frame is pushed onto the balance weight supporting plate.

Furthermore, in order to prevent the counterweight block from colliding with the counterweight frame when falling to cause damage, the lower end of the counterweight frame is provided with a cushion pad.

Further, when preventing to change the drum, the tray rises, be equipped with the spacing groove on the tray lateral wall, frame lateral wall downside be equipped with spacing groove complex recess, be equipped with in the recess with spacing groove complex stopper, the stopper with be equipped with the spring between the recess diapire, be equipped with the through-hole on the recess diapire, be equipped with the stay cord in the through-hole, stay cord one end with stopper fixed connection, the stay cord other end passes the through-hole extends to the frame outside.

When the wire coil is replaced, the tray is positioned at the bottom of the rack, and the limiting block is pushed by the spring to be inserted into the limiting groove, so that the tray is fixed at the bottom of the rack, and the tray is prevented from moving upwards along the rack under the action of the counterweight supporting plate to influence the replacement of the wire coil; the stay cord is used for dragging the stopper and overcomes the spring effort, makes the stopper break away from in the spacing groove indentation recess, and the tray loses the constraint and shifts up along the frame under the effect of counter weight layer board, risees the empty drum on the tray, assembles on the high-speed stranding machine.

The utility model has the advantages that: the utility model provides a pair of semi-automatic lifting device adopts tray, lifting unit and counter weight component to mutually support, with the ascending assembly of empty reel to high-speed stranding machine to and with the full drum decline of rolling unload the dish, stable in structure is reliable, has improved the security that full dish descends.
