Description

Technical Field

[0001] This utility model relates to the technical field of monitoring device installation equipment, and in particular to a novel mounting base for monitoring devices used for inspecting the appearance quality of tunnel fan support structures. Background Technology

[0002] The tunnel ventilation fan support structure is located at the top of the tunnel, requiring real-time inspection for potential hazards such as cracks at the welded joints of embedded parts and falling concrete. Previously, this inspection involved manual access to the tunnel top via a platform, a highly dangerous and safety-risk method. To address these issues, real-time monitoring devices were implemented. However, current installation involves manually bolting or screwing the devices onto the base. This is time-consuming and labor-intensive for large-scale operations, and furthermore, maintenance and inspection require removing all bolts and screws to detach the devices, resulting in high labor intensity and low work efficiency. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a novel mounting base for a monitoring device used to inspect the appearance quality of a tunnel ventilation fan support structure.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A novel mounting base for a monitoring device used to inspect the appearance quality of a tunnel ventilation fan support structure includes:

[0006] The enclosure is installed at the top of the monitoring area;

[0007] Two clamps are vertically installed inside the box, with the top of the clamps slidingly connected to the top of the inner wall of the box, and the clamping part is located outside the box.

[0008] The proximity sensor is located at the bottom of the enclosure;

[0009] The clamping drive mechanism is located inside the housing and is linked with the proximity sensor. It can drive the two clamps to move towards each other to clamp and fix the monitor.

[0010] The top of the inner wall of the box is equipped with a slide rail, which is slidably connected to two clamps.

[0011] The clamping drive mechanism includes:

[0012] Two electromagnet assemblies are installed inside the housing and correspond to the inside of the two clamps, respectively;

[0013] Two mounting blocks are installed inside the housing and are connected to the outside of the two clamps respectively via return springs;

[0014] The electromagnet assembly has a normally open contact of a proximity sensor connected in series, and the proximity sensor coil is connected in parallel to the normally open contact of the proximity sensor.

[0015] The top of the enclosure is equipped with a mounting plate, which is fixed to the top of the monitoring area by bolts.

[0016] The beneficial effects of this invention are as follows: This invention utilizes a proximity sensor to detect whether the monitor has entered the installation position. When the monitor enters the installation position, the coil of the proximity sensor is energized, the normally open contact of the proximity sensor closes, the electromagnet assembly is energized and magnetized, and the magnetic force generated by the two electromagnet assemblies magnetically attracts the two clamps inward, causing the two clamps to clamp the monitor, thus completing the installation of the monitor. The design of the return spring allows the two clamps to return to their initial state when the electromagnet assembly is de-energized. The design of the slide rail allows the two clamps to slide more smoothly. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] like Figure 1 and Figure 2As shown, a novel mounting base for a monitoring device used for inspecting the appearance quality of a tunnel ventilation fan support structure includes: a housing 8, mounted on the top of the monitoring area; two clamps 5, vertically arranged inside the housing 8, with the top of the clamps 5 slidably connected to the top of the inner wall of the housing 8, and the clamping part located outside the housing 8; a proximity sensor 7, located at the bottom of the housing 8; and a clamping drive mechanism, located inside the housing 8 and linked with the proximity sensor 7, capable of driving the two clamps 5 to move towards each other to clamp and fix the monitoring device. A slide rail 2 is provided on the top of the inner wall of the housing 8, and the slide rail 2 is slidably connected to the two clamps 5. The clamping drive mechanism includes: two electromagnet assemblies 6, located inside the housing 8 and corresponding to the inner sides of the two clamps 5 respectively; two mounting blocks 4, located inside the housing 8 and connected to the outer sides of the two clamps 5 respectively via return springs 3; wherein, a normally open contact 9 of the proximity sensor is connected in series on the electromagnet assembly 6, and the coil of the proximity sensor 7 is connected in parallel on the normally open contact 9. The top of the enclosure 8 is equipped with a mounting plate 1, which is fixed to the top of the monitoring area by bolts.

[0021] When using this invention, the worker positions the monitor directly in front of the center of the two clamps 5, and then approaches it near the bottom of the housing 8. When the proximity sensor 7 detects the monitor approaching, the coil of the proximity sensor 7 is energized, the normally open contact 9 of the proximity sensor closes, and the two electromagnet components 6 are energized and magnetized. At this time, the magnetic force generated by the two electromagnet components 6 magnetically attracts the two clamps 5 inward, causing the two clamps 5 to move and clamp the monitor, thus completing the installation of the monitor.

Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
