TECHNICAL FIELD
[0001] The utility model belongs to electromechanical equipment installation fastening technical field, especially a bottom foot support locking device suitable for large -scale machine pump installation. BACKGROUND
[0002] The upper end of the conventional anchor bolt generally protrudes the foundation plane, and when the machine pump equipment is transported to the site, the machine pump is hoisted to a certain height by hoisting equipment, and after the machine pump bottom foot hole is aligned with the anchor bolt, the machine pump is slowly placed on the foundation vertically, and after the machine pump is installed and debugged, the anchor bolt nut is tightened, and then the machine pump is tested and operated.
[0003] The large -scale machine pump is difficult to hoist due to large size and heavy weight, and when the traditional foundation is fastened by the anchor bolt, the following situations often occur: (1) when hoisting for the first time, the machine pump bottom foot is easy to collide and scratch the anchor bolt thread of the protruding foundation, and when the machine pump installation position is debugged in a large range of front and back, left and right, up and down, the anchor bolt thread of the protruding foundation and the surface matching surface of the foundation are also easy to scratch, which is not conducive to the centering and leveling of the motor shaft and the pump shaft, causing the vibration of the bearing and the rotor to increase, the temperature rise to increase, and the friction between the moving and static parts, the power loss, and even the running failure, the machine pump is stuck and stopped, and the enterprise is forced to stop production. (2) when the machine pump needs to be repaired, if it is set indoors, the large -scale machine pump is not easy to be hoisted out from the foundation for repair due to the limitation of the surrounding space and height, and it is easy to touch and scratch the anchor bolt thread of the protruding foundation, which is inconvenient to operate and affects the second time of reinstallation and debugging after repair. If it is set outdoors, if there is no large -scale hoisting equipment, the machine pump can only be dragged out from the foundation while being hoisted, which is easy to touch and scratch the anchor bolt thread of the protruding foundation and scratch the surface matching surface of the foundation, affecting the second time of reinstallation and debugging after repair; if large -scale hoisting equipment is used, the maintenance cost is increased.
[0004] It can be seen that the traditional foundation fastening method of the anchor bolt for the large -scale machine pump is not convenient for hoisting, installation, debugging and repair, and is easy to touch and scratch the anchor bolt thread of the protruding foundation, and is also easy to scratch the surface matching surface of the foundation, which is not conducive to the centering and leveling of the motor shaft and the pump shaft, causing the vibration of the bearing and the rotor to increase, the temperature rise to increase, and the friction between the moving and static parts, the power loss, and even the running failure, the machine pump is stuck and stopped, and the enterprise is forced to stop production.
