Abstract
The utility model provides an anti-looseness and anti-skidding device for flanged connection of medium and large cylinders. The anti-looseness and anti-skidding device for the flanged connection of medium and large cylinders comprises an iron block and a groove, the iron block is welded to the end face of one side, connected with a workbench, of a piston rod or a plunger rod, the groove is formed in the end face of one side, connected with the piston rod or the plunger rod, of the workbench, and the iron block and the groove are matched. The anti-looseness and anti-skidding device for the flanged connection of medium and large cylinders is simple in structure, easy and convenient to operate, and capable of effectively preventing looseness of the flanged connection, lowering equipment failure rate and guaranteeing equipment safety and personnel security.
Description
Technical field
The utility model belongs to the technical field of big-and-middle-sized oil pressure unit, relates in particular to the locking antiskid device that big-and-middle-sized cylinder flange formula connects.
Background technology
Big-and-middle-sized hydraulic press is mainly used in carrying out large-size spherical tank, and the compacting of storage tank finds that in the regular maintenance process of equipment the interior hexagonal trip bolt on flange that oil cylinder is connected with workbench often has the loosening even phenomenon of fracture.These loosening screws easily cause the screw thread stripped thread on oil cylinder in a short time, cause screw stressed and loosening landing completely, fracture, directly affect service life and normal production of equipment, also easily cause workbench to be caving, and lead to security incident.
Because the daily production of factory is various, hydraulic press is around-the-clock work, and oil cylinder is the groundwork position of hydraulic press.When oil cylinder is worked, piston rod (plunger rod) slides up and down, and has all the time the phenomenon of unbalance stress in the workbench all directions that connect oil cylinder in this process.Although the degree of unbalance stress is very little, piston rod in oil cylinder (plunger rod) is done back and forth movement and the relative motion that causes bar and workbench to produce a little for a long time, causes the loosening of screwed flange.Along with the continuity of service time is carried out, screwed flange continues to advance with loosening downwards state.When screwed flange moves to contact during workbench, in pressing process, become screwed flange stressed, now the trip bolt on flange just comes off and ruptures than being easier to, and flange is easy stripped thread and cause workbench to come off also, has serious potential safety hazard.
Traditional way is: the flange of running check oil cylinder is connected with non-loosening, if loosening, at once unloads the trip bolt on lower flange, again flange is upwards turned to the distance that makes its maintenance and workbench 6～8mm, then replaces with the trip bolt having damaged.Though the method can guarantee the safety of equipment, need to drop into more human and material resources, have a strong impact on operating efficiency and the safety of factory.
For solving, because flange connects loosening having influence on, produce and the problem of safety above, need to adopt a kind of new method, solve flange and connect loosening problem, guarantee safety and the efficiency of producing.
Summary of the invention
Technical problem to be solved in the utility model is the problem for above-mentioned existence, the locking antiskid device that provides big-and-middle-sized cylinder flange formula to connect, and this device can prevent loosening, the displacement that oil cylinder works long hours and causes.
The utility model solves the problems of the technologies described above adopted technical scheme: the locking antiskid device that big-and-middle-sized cylinder flange formula connects, it is characterized in that, comprise the iron block being welded on the side end face that piston rod or plunger rod be connected with workbench, with the groove, described iron block and the groove phase configuration that are arranged on the side end face that workbench is connected with piston rod or plunger rod.
Press such scheme, described iron block is two, on a relative side end face that is arranged at piston rod or plunger rod; Described groove is two, respectively at the corresponding setting of described iron block.
Press such scheme, between described iron block inner side end and groove inwall, be provided with the gap of 2～3mm
The beneficial effects of the utility model are: the locking antiskid device that this big-and-middle-sized cylinder flange formula connects, at easy loosening flange form connecting portion, add a locking antiskid device, rely on the cooperation of iron block and groove can effectively reduce equipment failure rate, improve the security performance of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.
Wherein: 1-oil cylinder, 2-piston rod or plunger rod, 3-fastening bolt, 4-screwed flange, 5-groove, 6-iron block, 7-workbench.
The specific embodiment
For understanding better the utility model, below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, the locking antiskid device that big-and-middle-sized cylinder flange formula connects, comprise the iron block 6 being welded on the side end face that piston rod or plunger rod 2 be connected with workbench 7, with the groove 5, iron block and the groove phase configuration that are arranged on the side end face that workbench is connected with piston rod or plunger rod.Iron block is two, on a relative side end face that is arranged at piston rod or plunger rod; Groove is two, respectively at the corresponding setting of described iron block.
The piston rod of the iron block of burn-oning or plunger rod 2 are connected by screwed flange 4, fastening bolt 3 with workbench 7.When in oil cylinder 1, piston rod or plunger rod are done back and forth movement for a long time, the cooperation of iron block 6 and groove 5 can fixed piston rod or plunger rod and workbench, effectively avoid piston rod or plunger rod and workbench to produce the relative motion of a little and cause the loosening of screwed flange, trip bolt is also not easy loosening and fracture, significantly extend maintenance personal's maintenance period, reduce equipment failure rate, improved production efficiency, equipment and personal safety have been ensured, iron block and groove leave the gap of 2～3mm, when piston rod or plunger rod motion, allow groove connecting portion produce cushion effect, be unlikely to damage the parts of connecting portion.
Claims (3)
1. the locking antiskid device that big-and-middle-sized cylinder flange formula connects, it is characterized in that, comprise the iron block being welded on the side end face that piston rod or plunger rod be connected with workbench, with the groove, described iron block and the groove phase configuration that are arranged on the side end face that workbench is connected with piston rod or plunger rod.
2. the locking antiskid device that big-and-middle-sized cylinder flange formula according to claim 1 connects, is characterized in that, described iron block is two, on a relative side end face that is arranged at piston rod or plunger rod; Described groove is two, respectively at the corresponding setting of described iron block.
