Embodiment Construction
[0034] Embodiment 1 of the switchgear inspection handcart in the present invention, the switchgear inspection handcart is used to detect whether the installation position of the static contact of the switchgear whose rail parallelism and verticality are qualified in the cabinet is appropriate, specifically as follows figure 1 , figure 2 and image 3 As shown, the inspection handcart includes a standard chassis car 1, which is equipped with a roller 2 for cooperating with the inner track of the switch cabinet. switch cabinet.
[0035] The detection handcart also includes a vehicle frame 3, which is installed on the chassis vehicle 1, and enters and exits the switch cabinet to be detected along with the chassis vehicle 1. The detection handcart also includes an insulating tube support 4 installed on the vehicle frame 3. The end of the insulating tube support 4 away from the vehicle frame 3 is coaxially equipped with a contact arm sleeve 5. The number of the insulator support ...

The invention belongs to the field of switch cabinet inspection devices, and in particular relates to a switch cabinet inspection handcart, including a chassis cart, which is used to cooperate with the switch cabinet and can enter and exit the switch cabinet; it also includes a static contact observation transparent plate, on which observation marks are arranged , and the reference point of the observation mark is on the axis of the moving contact of the standard switch cabinet handcart. When in use, push the inspection handcart into the switch cabinet, look straight at the static contact and observe the transparent plate. By observing the positional relationship between the static contact and the observation mark in the switch cabinet, you can accurately judge whether the installation position of the static contact is appropriate. If the profile of the head is dislocated relative to the observation mark, it can be determined that the installation position of the static contact is dislocated. At this time, the dislocation direction of the static contact can be determined according to the dislocation of the static contact relative to the observation mark, so that The switchgear inspection trolley can inspect the dislocation direction of the installation position of the static contact.
Description
technical field [0001] The invention belongs to the field of switch cabinet inspection devices, and in particular relates to a switch cabinet inspection handcart. Background technique [0002] At present, the standardization of switchgear handcarts is getting higher and higher, and the requirements for the precision of the structure of the switchgear itself and the precision of its cooperation with the handcart are also getting higher and higher. Among them, for the guide rail of the handcart in the switch cabinet, it is required to have high levelness and verticality to ensure that the handcart can slide smoothly to the working position along the guide rail; for the interlocking mechanism in the switch cabinet, it is required to be able to With flexible action and reliable and precise cooperation, the valve can be opened accurately and flexibly in place; the requirements for the installation position of the static contacts installed in the switch cabinet are even stricter, ...
