Embodiment Construction

[0018] A welding process for a safety gear base, which includes the following steps:

[0019] Step 1) Take the welding positioning plate and connect it with the inner side of the safety gear base with bolts;

[0020] Step 2) Take a pair of lower beam fixing plates and fix them by electric welding on both sides of the welding positioning plate. Check the size and verticality of 0.2 with a diagonal ruler. 7×30, the weld is full and free of defects;

[0021] Step 3) Take a pair of vertical beam fixing brackets, connect the opening positioning block with bolts in the middle, and then align with the three holes on the outer side of the safety gear base, and fix it by electric welding;

[0022] Step 4) After checking that the size is qualified, press fillet welding 5, intermittent welding 4×30, intermittent 10 welding, and remove the opening positioning block;

[0023] Step 5) Remove welding slag and fast mouth at the welding place;

[0024] Step 6) Spray gray paint on the weld. ...

Abstract

The invention discloses a welding process for a safety gear base, which comprises the following steps: 1) taking a welding positioning plate and connecting it with the inner side of the safety gear base with bolts; 2) taking a pair of lower beam fixing plates and fixing them on the welding positioning plate by electric welding Both sides of the square, diagonal ruler, check the size and verticality of 0.2, remove the welding positioning plate after passing, 4 intermittent welding at the corners of both sides, for 7×30, the weld is full and free of defects; 3) Take a pair of vertical beam fixing brackets , and connect the opening positioning block with bolts in the middle, and then align it with the three holes on the outer side of the safety gear base, and fix it by electric welding; 4) After checking the size is qualified, press fillet welding 5, intermittent welding 4×30, intermittent 10 welding, and remove The gear opening positioning block; 5) Remove welding slag and fast mouth at the welding place; 6) Spray gray paint on the welding place. The welding process of the invention can effectively ensure the welding fastness of the safety gear base.

Description

[0001] technical field [0002] The invention belongs to the field of elevators, in particular to an elevator safety gear device, and more specifically to a welding process for a safety gear base. [0003] Background technique [0004] The elevator safety gear device is a safety device that stops the car in an emergency and clamps it on the guide rail when the elevator has a very serious fault such as overspeed or broken rope under the control of the speed limiter. It provides effective protection for the safe operation of the elevator, and is generally installed on the car frame or counterweight frame. [0005] The safety gear device may ensure the safety of the people in the car when a dangerous situation occurs in the elevator, but if there is a problem with the safety gear device itself, this first aid measure will disappear. At present, the safety gear device is basically fixed on the car or the counterweight frame through the safety gear base, while the existing safe...
