Description

Technical Field

[0001] This utility model relates to the technical field of monitoring device installation equipment, and in particular to a monitoring device mounting bracket for inspecting the appearance quality of a tunnel fan support structure. 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, inspections were conducted manually from a platform reaching the tunnel top, a highly dangerous and safety-risk method. To address these issues, real-time monitoring devices were implemented. However, current installation involves manual on-site bolting or screwing the devices to their bases. This is time-consuming and labor-intensive for large-scale operations, and furthermore, maintenance and inspection require complete removal of all bolts and screws to disassemble the devices, resulting in high labor intensity and low efficiency. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a monitoring device mounting bracket for inspecting the appearance quality of tunnel ventilation fan support structures.

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

[0005] A mounting bracket for monitoring the appearance quality of a tunnel ventilation fan support structure includes:

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

[0007] The insertion holes are vertically positioned inside the box.

[0008] The proximity sensor is located inside the socket.

[0009] The connecting rod is inserted into the socket;

[0010] The mounting component, located at the bottom of the connecting rod, is used to place the monitor.

[0011] The connecting rod locking mechanism is located inside the housing and is linked with the proximity sensor to lock the connecting rod.

[0012] The top of the enclosure is equipped with a mounting plate, which is fixed to the top of the monitoring area by bolts.

[0013] The connecting rod locking mechanism includes:

[0014] The electromagnet assembly is housed inside the enclosure and located on one side of the socket;

[0015] A slider is set on one side of the electromagnet assembly and is slidably connected to the bottom of the housing. A horizontal insertion plate is set on it, and the insertion plate corresponds to the first small insertion hole on the electromagnet assembly, the second small insertion hole on the side wall of the insertion hole, and the positioning hole on the side wall of the connecting rod in sequence.

[0016] The mounting block is located on one side of the slider and is connected to the slider via a return spring;

[0017] 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.

[0018] The bottom of the connecting rod is connected to the mounting assembly via a ball joint, allowing the mounting assembly to rotate in all directions.

[0019] The installation components include:

[0020] Door-shaped components, used to house surveillance cameras;

[0021] The base plate is detachably installed at the bottom of the door-shaped component.

[0022] The beneficial effects of this utility model are as follows: This utility model uses a proximity sensor to detect whether the connecting rod has entered the installation position. When the connecting rod is inserted into the socket and enters the installation position, the proximity sensor in the socket detects the connecting rod, the coil of the proximity sensor is energized, the normally open contact of the proximity sensor is attracted, the electromagnet assembly is energized and magnetized, and the slider is magnetically attracted. At this time, the slider slides onto the electromagnet assembly, and the insert plate is inserted into the first small socket, the second small socket and the positioning hole on the side wall of the connecting rod in sequence to lock the connecting rod and complete the installation.

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.

[0026] like Figure 1 and Figure 2As shown, a monitoring device mounting bracket for inspecting the appearance quality of a tunnel ventilation fan support structure includes: a housing 2, installed at the top of the monitoring area; a socket 6, vertically installed inside the housing 2; a proximity sensor 5, installed inside the socket 6; a connecting rod 8, inserted into the socket 6; a mounting assembly, located at the bottom of the connecting rod 8, for placing the monitor; and a connecting rod locking mechanism, located inside the housing 2, which is linked with the proximity sensor 5 to lock the connecting rod 8. A mounting plate 1 is provided on the top of the housing 2, and the mounting plate 1 is fixedly installed on the top of the monitoring area by bolts. The connecting rod locking mechanism includes: an electromagnet assembly 4, disposed inside the housing 2 and located on one side of the insertion hole 6; a slider 3, disposed on one side of the electromagnet assembly 4 and slidably connected to the bottom of the housing 2, with a horizontally arranged insertion plate 7 on it, the insertion plate 7 corresponding sequentially to the first small insertion hole on the electromagnet assembly 4, the second small insertion hole on the side wall of the insertion hole 6, and the positioning hole on the side wall of the connecting rod 8; and a mounting block 13, disposed on one side of the slider 3 and connected to the slider 3 via a return spring 12; wherein, a normally open contact 14 of a proximity sensor is connected in series on the electromagnet assembly 4, and a coil of a proximity sensor 5 is connected in parallel on the normally open contact 14 of the proximity sensor.
