Abstract
The utility model relates to a single person-operated anti-falling device for mechanical maintenance, comprising an agitated reactor upper cover body. The top of an agitator blade extends upwards out of the upper cover body to be connected with a motor. The innovation points of the device are as follows: a vertical pin shaft is welded at the upper end surface of the upper cover body at one side of the agitator blade and connected with a front hoop and a rear hoop; one ends of the front hoop and the rear hoop are connected by the pin shaft; the outer side of the other end of the front hoop is opened; the other end of the rear hoop is provided with a screw rod pin-jointed with the rear hoop; and the screw rod is in sliding fit with a nut. The single person-operated anti-falling device for mechanical maintenance has the advantages that when the agitated reactor is disassembled, only the nut needs to be screwed up, so that the front hoop and the rear hoop clamp the end part of the agitator blade to prevent the agitator blade from falling into the agitated reactor body when a speed reducer is disassembled. An operator does not need to pick up by entering the agitated reactor body, so that the harm chemical substances of to the operator can be avoided; and the anti-falling device can be operated by a single person, and is convenient to use.
Description
Technical field
The utility model relates to a kind of one man operation's flight-line maintenance anti-drop device, particularly a kind of fixing dismounting auxiliary equipment of chemical reaction still paddle that is used for.
Background technology
The chemical reaction still is when its reductor of dismounting, and connected paddle easily falls into reaction kettle body, needs operating personnel to enter in the kettle and picks up, the kettle charging aperture is less, be difficult for entering, and be chemical substance in the kettle, operating personnel's health is caused certain injury and potential risk.A kind of one man operation's flight-line maintenance anti-drop device has also appearred at present, the two halves anchor ear that utilization is located on the upper cover body is clamped the paddle end, the paddle that prevents to disassemble behind the motor drops, this structural disadvantages is: anchor ear is fixed on the upper cover body by support, two ends, and support and anchor ear length are all longer, waste material, and fixedly during paddle, need two ends to fix, use cumbersome.
The utility model content
The technical problems to be solved in the utility model provides a kind of one man operation's flight-line maintenance anti-drop device easy to use.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of one man operation's flight-line maintenance anti-drop device, comprise the reactor upper cover body, the top of paddle protrudes upward upper cover body and is connected with motor, its innovative point is: be welded with the bearing pin of a vertical direction in the upper cover body upper surface of paddle one side, be connected with forward and backward anchor ear on the described bearing pin; One end of described forward and backward anchor ear connects by this bearing pin, the other end outer openings of preceding anchor ear, and the other end of back anchor ear is provided with the screw rod with back anchor ear pin joint, is equipped with nut on screw rod.
Advantage of the present utility model is: when carrying out the dismounting of reactor, only need screw nut, make forward and backward anchor ear clamp the paddle end, paddle falls in the kettle when avoiding dismantling reductor.Need not manually to enter in the kettle to pick up, avoid the harm of chemical substance operating personnel, single can the operation, easy to use.
Description of drawings
Fig. 1 is the utility model one man operation flight-line maintenance anti-drop device front view;
Fig. 2 is the utility model one man operation flight-line maintenance anti-drop device vertical view.
The specific embodiment
As shown in Figure 1, 2, comprise reactor upper cover body 1, paddle 2, bearing pin 3, preceding anchor ear 4, back anchor ear 5, screw rod 6, nut 7.
The top of above-mentioned paddle 2 protrudes upward the upper cover body 1 of reactor, and is connected with motor, and bearing pin 3 is vertically set on top one side of paddle 2, and its bottom is fixing with the welding of upper cover body 1 upper surface.One end of forward and backward anchor ear 4,5 connects by this bearing pin 3, the other end outer openings of preceding anchor ear 4, and the other end of back anchor ear 5 is provided with the screw rod 6 with back anchor ear 5 pin joints, is equipped with nut 7 on screw rod 6.
