Technical Field

[0001] This utility model relates to the field of mounting bracket technology, and in particular to a mounting bracket for coal mine ventilation equipment. Background Technology

[0002] Coal mine ventilation equipment mounting brackets are support structures designed for underground ventilation systems in coal mines, primarily used to fix and support the position of ventilation equipment (such as fans, ventilation ducts, etc.). In the coal mine working environment, ventilation equipment is crucial for ensuring underground air circulation, reducing gas concentration, and preventing dust accumulation. However, it is worth considering that traditional mounting brackets cannot be folded, making transportation and storage difficult, and they are hard to deploy in narrow tunnels. Many brackets use welded fixings or non-adjustable support legs, which cannot be adjusted to suit different usage scenarios, thus limiting their practicality.

[0003] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an installation bracket for coal mine ventilation equipment, so as to solve the problem that many of the above-mentioned brackets are fixed by welding or have non-adjustable support legs, which cannot be adjusted according to the usage scenario, thus limiting their practicality.

[0005] To achieve the above objectives, this utility model provides an installation bracket for coal mine ventilation equipment, including a support platform, a lifting seat above the support platform, a bracket rotatably connected to the top of the lifting seat, and a lifting structure for driving the lifting seat to move vertically on the support platform.

[0006] The support platform has several grooves, and the lower part of the lifting seat has several support legs. The number of grooves is the same as the number of support legs. The bottom end of the support leg is located in the corresponding groove. The two sides of the support leg are respectively provided with sliding grooves. The support column is slidably provided in the sliding groove and is fixedly connected to the inner wall of the groove. The support platform is equipped with a positioning component for positioning the support leg.

[0007] Preferably, the lifting structure includes a lead screw fixedly installed at the bottom of the lifting seat, a threaded sleeve is provided on the outer thread of the lead screw, the threaded sleeve passes through the support platform, the threaded sleeve and the support platform are rotatably connected, and a guide component that cooperates with the support platform is installed on the lifting seat.

[0008] Preferably, the guide component includes at least one guide column fixedly installed at the bottom of the lifting seat, a guide sleeve is slidably sleeved on the outside of the guide column, and the bottom end of the guide sleeve is fixedly connected to the top of the support platform.

[0009] Preferably, the bottom end of the threaded sleeve is fixedly connected to a support portion located below the support platform. The support platform has several through holes, and a first bolt is provided below the lifting seat. The first bolt passes through the corresponding through holes, and the bottom end of the first bolt passes through the support portion.
