Abstract
A diversion sluice gate operating-abnormal protection device comprises a spring, a bolt, a regulating nut, a limit switch, a steel sheet, and an enclosing cover. The lower end of the bolt works out an internal thread with depth of 30 mm and the size of a thread and a built-in bolt is the same to heighten the bolt. The upper end works out the thread with the diameter of 4*10 mm to fix the enclosing cover. A steel sheet is arranged between the regulating nut and the spring and two holes are arranged on the steel sheet. The hole should be the same as the bolt in size and the hole should be the same as a stud of the limit switch in size. The nut arranged on the stud of the limit switch is used to fix the limit switch on the steel sheet. When a flashboard encounters a foreign body or is hindered in the process of falling, the reacting force of a leading screw leads an on-off engine base 2 and a fixed steel plate 5 to disengage from a gate room floor to lift upwards, and meanwhile the fixed steel plate 5 compresses the spring 10. When the spring is compressed to reach a set stroke of 3 mm, the limit switch 13 is acted with the normal- closed contact disconnected and a motor power supply is switched off to stall the motor, thereby the accidents are avoided.
Description
Technical field
The utility model belongs to a kind of keying control technology field of sluice gate, specially refers to a kind of diversion sluice gate operation exception protective device.
Background technology
At present, extensive use screw type culverts and water gates headstock gear in a lot of culverts and water gates, as shown in Figure 1: it is to be combined by screw by support 2 and monoblock steel plate 5, and steel plate combines by screw 4 with lock house floor 7 again, and screw 4 is embedded on the lock house floor 7.In flashboard 6 decline processes,, reasons such as mud, foreign material are arranged under the lock can not continue to fall owing to causing flashboard to be obstructed, and the headstock gear motor is still changeing, under the drive of reductor, the reaction force of leading screw 1 can be broken top, the floor in lock room, and serious accident takes place.
Summary of the invention
Purpose of the present invention: in order to overcome the deficiency of prior art, gate operation exception protective device 3 is installed on the support 2 of above-mentioned culverts and water gates headstock gear, a kind of gate operation exception protective device promptly can be provided.Have advantages such as quick action, reliable in action, stable performance, processing be simple, easy for installation.
To achieve these goals, the utility model is realized by following technical proposals: a kind of diversion sluice gate operation exception protective device, mainly formed by spring, bolt, adjusting nut, limit switch, steel plate, outer cover, it is characterized in that: process dark 30mm internal thread in the lower end of bolt, pre-embedded bolt consistent size on thread size and the floor is used for increasing bolt; The upper end processes diameter 4 * 10mm screw thread, is used for fixing outer cover, and a steel plate is arranged between described adjusting nut and the spring, limit switch is installed on the steel plate, adjusting nut, making limit switch contact and opening-closing machine base interplanar spacing is to get final product about 3mm, limit switch is only used constant close contact.Two holes are arranged above the described steel plate shape, and the hole should be consistent with the bolt size, and the hole should be consistent with the double-screw bolt size of limit switch, with the top nut of limit switch double-screw bolt limit switch is fixed on the steel plate.
Good effect of the present utility model and advantage: by the above when flashboard runs into foreign matter and is obstructed in dropping process, the reaction force of leading screw can make opening-closing machine base 2 and fixation steel plate 5 break away from the lifting that makes progress of lock house floors, fixation steel plate 5 can compress spring 10 simultaneously, length of spring compressed reaches when setting stroke 3mm, limit switch 13 actions, constant close contact disconnects, and cuts off motor power and makes the motor stall, thereby avoided the generation of accident.Advantage such as have reliable in action, stable performance, processing is simple, easy for installation, wiring is simple.
Description of drawings
Fig. 1 provides the structural representation of a culverts and water gates headstock gear.
Fig. 2 provides the structural representation of gate operation exception protective device.
Fig. 3 provides the steel plate schematic diagram that limit switch is installed.
The specific embodiment
Below provide an embodiment: the utility model mainly is made up of spring 10, bolt 11, adjusting nut 12, limit switch 13, steel plate 14, outer cover 15 as shown in Figure 2.Wherein bolt 11 lower ends process dark 30mm internal thread, and pre-embedded bolt 8 consistent size are used for increasing bolt 8 on thread size and the floor; The upper end processes diameter 4 * 10mm screw thread, is used for fixing outer cover 15; One steel plate 14 is arranged between adjusting nut 12 and the spring 10, as shown in Figure 3, limit switch 13 is installed on the steel plate 14.Adjusting nut 12, making limit switch 13 contacts and opening-closing machine base 2 interplanar spacings is to get final product about 3mm, 13 of limit switches are used constant close contact.Steel plate 14 shapes have two holes as shown in Figure 3 above, and hole 16 should be consistent with bolt 11 sizes, and hole 17 should be consistent with the double-screw bolt size of limit switch 13, with the nut on the limit switch double-screw bolt limit switch is fixed on the steel plate.More than used parts in addition and material be commercial prod.
Can constitute the utility model according to above-mentioned making---a kind of diversion sluice gate operation exception protective device.
