Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
See Fig. 1, a kind of safety supporting device of hydraulic lifting gate, has:
Dam body, dam body lower end is installed with lower shaft;
Lower shaft bearing, lower shaft is installed in rotation on lower shaft bearing;
Be fixed on the limited block on lower shaft, limited block is provided with breach;
Piston rod;
Be arranged on the rest pad on the piston rod of piston rod, rest pad can stretch into or stretch out in the breach of limited block under the drive of piston rod, as shown in Figure 3 and Figure 5;
The position of breach makes: when dam body is upright, and rest pad can stretch in the breach of limited block, and locks the rotation of dam body.Conventional sense lower support block does not stress, and when gate rises to extreme higher position, start piston rod promotion rest pad and reach in the breach of limited block, the gate preventing master cylinder pressure release from causing surprisingly is opened.
Drive the main hydraulic cylinder peripheral hardware hydraulic lock of gate opening/closing, the unexpected pressure release of anti-locking system.When the unexpected pressure release of system causes main hydraulic cylinder piston rod to shrink, rest pad holds gate limited block, guarantees that gate can not surprisingly be opened.
When needing to fall dam, start small oil tank and return rest pad, main hydraulic cylinder drives gate opening.As shown in figures 1 and 3, be the contrast schematic diagram of two states.
It is the mounting hole of above-below direction that rest pad installs the installing hole of piston rod, and the position of mounting hole makes rest pad can change upper-lower position on the piston rod.Rest pad interposition installs mounting hole, size and piston rod installation position suitable; This rest pad can slide up and down along the vertical radial direction of piston rod, prevents because the corrosion of lower shaft bearing or spot cause rest pad jam and limitation of movement.
Piston rod is hydraulic cylinder, and hydraulic cylinder is fixedly mounted on lower shaft bearing, and the direction of motion of piston rod is horizontal direction.By the horizontal movement of piston rod rest pad pushed or release limited block.Rest pad lower end plane is positioned in lower shaft bearing plane, flexible along lower shaft bearing slide anteroposterior with piston rod.The direction of motion due to the piston rod of hydraulic cylinder is horizontal direction, no matter is that hydraulic cylinder does not all stress in bearing state or dislocation state.Only have when needs drive rest pad to retreat, in hydraulic cylinder oil pocket, just need have pressure requirements, therefore, there is not the unexpected decompression of small cylinder and the safety problem that produces.
As shown in Figure 4, limited block cross section is semicircle, and semicircular section is breach; Rest pad is square, the end face of rest pad and the section adaptation of limited block.
As shown in Figure 2, lower shaft bearing both sides are respectively provided with one group of limited block, rest pad and hydraulic cylinder.Lower shaft bearing has two.Lower shaft bearing both sides are respectively fixed with a limited block, each limited block corresponds on lower shaft bearing and is provided with a small cylinder, vertical floodgate lower shaft direction, small cylinder piston rod outer end is arranged, piston rod outer end corresponds to limited block position and is provided with rest pad, and rest pad and piston rod are slidably connected.
Small cylinder manually can operate the motion of hydraulic power unit piston rod under power failure state, returns rest pad.Therefore, when the flood swelled in volume and dead electricity situation occurs, all realize safety by manual pressure release and put dam, the gate eliminating existing band supporting bar structure can not put the potential safety hazard on dam under power failure state.Hydraulic cylinder is installed on lower shaft bearing, without the need to independently installing built-in fitting, reduces installation cost.Supporting arrangement is in hidden installation site bottom gate, takes up room little, simplifies gate external structure, reduces installing space, strengthens landscape effect.
After adopting above-mentioned structure, conventional sense lower support block does not stress, and when gate rises to extreme higher position, promote rest pad and reach below limited block, locking limited block, the gate preventing master cylinder pressure release from causing surprisingly is opened, and improves the safety on the dam that hoists.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
