Abstract
The utility model relates to mechanical equipment, in particular to a hydraulic safety cock. The hydraulic safety cock comprises a base and a hook. An oil cylinder is arranged at the lower end of the base, the oil cylinder is connected with a pin shaft, and a connecting hole is formed in the upper end of the hook. The base and the hook are respectively clamped on an upper cross beam and a sliding block of a hydraulic pressure machine. When the pressure machine operates normally, the pin shaft is pulled out of the connecting holes, and the sliding block can move freely. When the pressure machine is shut down, the pin shaft is inserted into the connecting hole, the sliding block is locked, moving of the sliding block is limited, the potential safety hazards of working on the pressure machine are eliminated, and safety of working staff in the process of operation on the pressure machine is guaranteed.
Description
Technical field
The utility model relates to plant equipment, specifically is a kind of hydraulic safe bolt.
Background technology
Hydraulic press is a kind of important machining equipment, is mainly used in the press forming workpiece, proofreaies and correct steel plate, shaped steel and structural member etc., and choosing is adorned different moulds and can be realized above-mentioned different function, and application is comparatively extensive.Need change adaptive mould and upper table examining workpieces during the hydraulic pressure machine operation, because the leakage of hydraulic system or the misoperation of various valves, also or operating personnel's maloperation, all might cause the unexpected decline of slide block or descending, there is bigger potential safety hazard, serious threat personnel and device security.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic safe bolt of simple in structure, security of operation.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of hydraulic safe bolt comprises base and hook, and the base lower end is provided with oil cylinder, and oil cylinder connects a bearing pin, and described hook upper end is provided with connecting hole.
Be connected with collision block on the described bearing pin.
The utility model is installed on base and hook respectively on the entablature and slide block of hydraulic press.When forcing press normally moves, bearing pin is extracted from connecting hole, slide block can move freely; When forcing press is shut down, bearing pin is inserted in the connecting hole, the locking slide block limits it and moves, and has eliminated the potential safety hazard of last machine work, guarantees that the staff goes up the affected safety of machine.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is locking state figure of the present utility model.
Among the figure: 1, oil cylinder, 2, base, 3, bearing pin, 4, hook, 5, collision block, 6, connecting hole, 7, entablature, 8, slide block.
The specific embodiment
A kind of hydraulic safe bolt as shown in Figure 1 comprises base 2 and hook 4, and base 2 and hook 4 are installed on respectively on the entablature 7 and slide block 8 of hydraulic press, and hook 4 moves up and down with slide block 8.Base 2 lower ends are provided with oil cylinder 1, and oil cylinder 1 connects a bearing pin 3, and described hook 4 upper ends are provided with connecting hole 6.
When integral device is worked as shown in Figure 2; it is up that slide block 8 drives hook 4, and oil cylinder 1 promotes bearing pin 3 and move to the right to insert and link up with in 4 the connecting hole 6 when walking to top dead-centre and need protection, and bearing pin 3 docks with connecting hole 6; it is up that locking slide block 8 can not continue it, plays a protective role.When slide block 8 was descending, oil cylinder 1 retracted bearing pin 3 and moves left, and hook 4 and bearing pin 3 break away from, and remove locking state.Not only make and also played the position limitation protection effect by slide block 8 reciprocal easy motions.In addition, collision block 5 is installed also on the bearing pin 3, collision block 5 limits the movement travel of oil cylinders 1, guarantees insertion and the extraction distance of bearing pin 3, and operation more precisely puts in place.
Claims (2)
