Embodiment Construction
[0025] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0026] see Figure 1-5 , In this embodiment, the frame 1 is a combined frame, which consists of three cuboid frames stacked up and down and connected by bolts. The frames at the middle and the bottom are also welded with diagonal braces. A support 21 is installed on the bottom of the frame 1, and the support 21 assembles the electric hoist 13 through the installation pin 18. The top of frame 1 is installed two groups of (totally four) transmission chain shaft bearings 17, and a pulley shaft 20 is housed between every group of transmission chain shaft bearings 17, and a pulley 16 is cooperated outside the pulley shaft 10. The electric hoist 13 winds the steel cable 19. The outer end of the steel cable 19 extends to the upper part of the frame 1 and passes through the two pulleys 16 in turn. The bottom is connected with the electronic we...

The invention discloses elevator buffer testing equipment, which comprises a frame, wherein a counterweight block tray is arranged on the frame, the counterweight block tray is used for superposing counterweight blocks, and each counterweight block is provided with a jack; an electric hoist is arranged on the frame, a steel cable is wound on the electric hoist, the extending end of the steel cable is connected with a separation hook, the separation hook hooks a load box body on the lower part, the separation hook can be separated from the load box body, and one side of the load box body, which faces one side of the counterweight blocks, is not closed; and a counterweight lifting motor is arranged on the frame, the counterweight lifting motor drives a lifting lead screw of a counterweight mechanism to rotate, the lifting lead screw of the counterweight mechanism propels the counterweight mechanism to ascend or descend through threads, the counterweight mechanism is provided with a counterweight block moving motor, the counterweight block moving motor drives a lead screw to rotate, the lead screw propels a guide rail to transversely move through threads, the lower part of the guide rail is opposite to the counterweight blocks, the guide rail is provided with counterweight block propelling pins, and the counterweight block propelling pins can be inserted into the jacks of the counterweight blocks, so that the guide rail transversely moves and the counterweight blocks can be filled in or moved out of the load box body.
Description
technical field [0001] The invention belongs to the technical field of elevators, in particular to a test device for elevator safety components, in particular to a test device for an elevator buffer. Background technique [0002] Elevator is a kind of vertical lifting transportation equipment, which is used to carry passengers or goods, and is a necessary transportation equipment for high-rise buildings. The hydraulic buffer is a safety component that must be configured according to the national standard GB7588. When the elevator runs over-travel, that is, squatting to the bottom or rushing to the top, it acts as a buffer, reduces risks, and protects passengers, goods and the elevator itself. [0003] According to the national standard, the hydraulic shock absorber must be subjected to regular type tests. The type test method is to use a heavy block of a certain weight to freely fall from a corresponding height to impact the hydraulic shock absorber, and to record the accele...
