Description
The utility model relates to the anti-drop device of hydraulic lifting scaffold for building.
The hydraulic lifting scaffold is that the bidirectional hydraulic jack is installed on the nethermost operating platform, inserts pole-climbing in the bidirectional hydraulic jack.Start hydraulic control.The bidirectional hydraulic jack just moves up and down in pole-climbing, drives operating platform simultaneously and does oscilaltion.The bidirectional hydraulic jack has up and down dop, will self be locked in the pole-climbing, and when the pole-climbing fracture or dop is malfunctioning up and down, whole scaffold can cause personal injury from falling in the air, and equipment damages.
The purpose of this utility model is the anti-drop device that the hydraulic lifting scaffold is provided in order to overcome above-mentioned weak point, when pole-climbing disconnection or hydraulic jack self dop is malfunctioning up and down the time, whole scaffold can not avoid personal injury and equipment to damage from falling in the air.
Description of the present utility model is as follows: whole anti-drop device is installed in the top of hydraulic jack.Anti-drop device by hoisting mechanism, clamping pin mechanism, link the rope form.Hoisting mechanism, clamping pin mechanism link rope on the same floor levels face above the hydraulic jack.Hoisting mechanism is positioned at the centre position, and it is made up of cantilever beams, spring base, compression spring, cover plate, pole-climbing, and pole-climbing links together by screw thread and cover plate, and cantilever beams is fixed on the floor face.Mounting spring seat on cantilever beams is against on the cover plate above the compression spring, and is on the cover board porose.Under normal circumstances, the weight of hydraulic jack and pole-climbing makes cover plate be connected with plane on the spring base and touches greater than the tension force of compression spring.And dop is malfunctioning up and down when pole-climbing disconnection or hydraulic jack, and pole-climbing loses weight and makes cover plate up and leave plane on the spring base by the tension force of compression spring.Narrate clamping pin mechanism below, clamping pin mechanism be installed in hydraulic lifting scaffold fluctuating orbit above, a clamping pin mechanism is respectively arranged in the hoisting mechanism both sides.Bar batten with grid is arranged between clamping pin mechanism and scaffold, and bar batten is connected with scaffold.Clamping pin mechanism is made up of cylindrical shell, compression spring, pressing plate, pin, load axle.Clamping pin mechanism is transverse state, in the cylinder lumen bottom compression spring is arranged, and at the cylindrical shell oral area load axle is arranged, and load axle inner end is fixed with pressing plate.Pressing plate outer big through outer warp than load axle.There is a breach inboard, middle part at cylindrical shell, in indentation, there pin is arranged, and the inner end of pin is against on the omoplate of pressing plate, and there is pin-and-hole the outer end of pin.Under the compression spring action, pin is blocked by pressing plate.Narration links the connection of rope below.The medial head that links rope ties up on the hole of hoisting mechanism cover plate, and the head at its two ends respectively ties up on the pin-and-hole of pin in the clamping pin mechanism by fixed pulley.In normal condition, the plane contacts on the cover plate of hoisting mechanism and the spring base, and the pin of clamping pin mechanism is blocked by pressing plate by the compression spring; When the last lower chuck that pole-climbing disconnection or hydraulic jack self take place malfunctioning, pole-climbing in the hoisting mechanism is up and to drive cover plate up under the spring action in compression, cover plate affects to link on the rope and draws, and transfer to pin in the clamping pin mechanism link rope two, under the effect of compression spring, load is axially outer to be stretched out, its end reaches in the grid on the canopy batten, because bar batten is fixed on the scaffold, fluctuating orbit is fixed on the floor face, the institute so that whole hydraulic lifting scaffold be suspended in the air, under the unlikely bob.
