Abstract
The utility model discloses a lifting nut pair with an abrasion detection device. A driving set comprises a driving nut, a driving bracket and a safety upper shifting fork, wherein the driving nut is installed on the driving bracket through a bolt, and the safety upper shifting fork is connected with the driving nut through the bolt; a driven set comprises a safety lower shifting fork, a safety nut and an electrical detection switch, wherein the safety lower shifting fork is connected with the safety nut through the bolt, the electrical detection switch is installed on the driving bracket, and the safety nut and the driving nut are indirectly connected through the safety upper shifting fork and the safety lower shifting fork; both the driving set and the driven set are installed on a lifting screw rod; and a gap is arranged between the safety lower shifting fork and the safety nut. According to the utility model, the gap is produced by means of the abrasion between the screw rod and the nuts; and a proximity switch is adopted as a detection element to detect a preset gap, inform a control system to give an alarm, and remind of an operator that maintenance and replacement are required; therefore, great convenience for the operation is realized; meanwhile, sudden failures of equipment are avoided; and the safety coefficient is improved.
Description
Technical field
The utility model relates to a kind of detection device, is specifically related to a kind of lifting nut pair of belt wear detection device.
Background technique
Lifting drive system mainly is made up of trapezoidal screw, lifting nut, drive unit, counterweight etc.The slide lifting drives power and is driven through worm reducer by AC motor, by screw-nut body with transmission of power to slide and upset dish, by the linear rail guiding, realize the elevating movement of slide and upset dish.Screw mandrel adopts trapezoidal screw, and feed screw nut pair and worm reducer all have auto-lock function, and slide can accurately be located the arbitrary position in range.
Lifting nut mainly is made up of nut frame, drive nut and jam nut.When drive nut is long-term use in during wear and tear overrun, jam nut contacts with threads of lead screw, thereby prevents that slide from dropping.Because jam nut and leading screw friction locking must could run well behind the replacing drive nut, thereby the security incident that causes because of the nut wearing and tearing in preventing to use for a long time.
Although being provided with the jam nut device prevents from security incident to occur because of nut has worn and torn.But because jam nut and leading screw friction locking must could run well behind the replacing drive nut.Change nut after each replacing jam nut and the leading screw friction locking and comparatively bother, do not have the lifting nut of special band detection device so far.
The model utility content
The utility model has overcome the deficiencies in the prior art, and a kind of easy-to-operat is provided, and avoids the lifting nut pair of the belt wear detection device that equipment breaks down suddenly simultaneously, has solved the technical problem that the nut wearing and tearing can't detect.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of lifting nut pair of belt wear detection device, this pair of nut comprises active set and driven group, active set comprises fork on drive nut, driving arm, the safety, and wherein drive nut is installed on the driving arm by bolt, also is connected with drive nut by bolt and go up fork safely; Driven group comprises safety fork, jam nut and electrical equipment detecting switch down, and wherein fork is connected with jam nut by bolt under the safety, and the electrical equipment detecting switch is installed on the driving arm, and jam nut is connected by the upper and lower fork of safety indirectly with drive nut; Active set and driven group are installed on the elevating screw, and safety leaves the gap between fork and the jam nut down, rotate by elevating screw and make the drive nut lifting, drive nut by driving arm with transmission of power.
Further technological scheme is:
Described gap is 1/4th of a pitch.
Described electrical equipment detecting switch is connected with electrical apparatus control system.
The electrical equipment detecting switch be have normally opened contact near switch.
The electrical equipment detecting switch is installed on the spring, is connected with driving arm by spring again, and the working stroke of spring is less than the gap.
Compared with prior art, the beneficial effects of the utility model are: the lifting nut pair that a kind of belt wear detection device is provided, this device utilizes the wearing and tearing between leading screw and the nut to produce the gap, adopt simultaneously near switch as Detecting element, detect the gap of presetting, the notice control system is reported to the police, remind the operator to keep in repair and to change, greatly facilitate operation, also avoided equipment to break down suddenly simultaneously, improved safety coefficient.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, a kind of lifting nut pair of belt wear detection device, this pair of nut comprises active set and driven group, active set comprises fork 3 on drive nut 1, driving arm 2, the safety, wherein drive nut 1 is installed on the driving arm 2 by bolt, also is connected with drive nut 1 by bolt and go up fork 3 safely; Driven group comprises safety down fork 4, jam nut 5 and electrical equipment detecting switch 6 (have normally opened contact near switch), wherein fork 4 is connected with jam nut 5 by bolt under the safety, electrical equipment detecting switch 6 is installed on the spring 8, be connected with driving arm 2 by spring 8, the working stroke of spring 8 is less than gap 7 again.Electrical equipment detecting switch 6 is connected with electrical apparatus control system, and jam nut 5 is connected by the upper and lower fork 3,4 of safety indirectly with drive nut 1; Active set and driven group are installed on the elevating screw, and safety leaves the gap between fork 4 and the jam nut 5 down, and gap 7 is roughly 1/4th of pitch.Make drive nut 1 lifting by the elevating screw rotation, drive nut 1 passes through driving arm 2 with transmission of power, thereby realizes the equipment load lifting function; Simultaneously, jam nut 5 is elevating movement together also, still, owing to connect by fork between jam nut 5 and the drive nut 1, so 5 of jam nuts are done uncharged elevating movement.In use, drive nut 1 is under loading, and the thread form of screw thread can be worn, and this moment, driven group relative position was constant, and active set will descend for driven relatively group, and the amount of decline is the amount that is worn.When the amount that descends exceeded setting value, the electrical equipment detecting switch was thrown off, and electrical apparatus control system is made warning, and prompting must be changed nut and can normally use.
