Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mining equipment, and in particular to a hoisting frame for mine ventilation ducts. Background Technology
[0002] During coal mine mining operations, due to the low air saturation underground, workers need to use ventilation equipment to supply air to the mine. The application of coal mine ventilation ducts helps maintain a reasonable gas composition within the mine. Existing technology publication CN212250143U proposes a coal mine ventilation duct mounting frame that facilitates fixation. This frame includes a duct body with a first and a second pipe opening fixedly connected to its left and right ends, respectively. Multiple evenly distributed reinforcing steel rings are fixedly connected to the inner wall of the duct body, and multiple evenly distributed fixing rings are movably connected to the outer wall of the duct body. Each fixing ring has an inner groove matching the reinforcing steel ring, and the inner wall of the groove engages with the reinforcing steel ring through the duct body. A connecting block is fixedly connected to the upper end of the outer wall of the fixing ring, and a hanging ring is fixedly connected to the upper end of the connecting block. The first pipe opening is placed inside the mine shaft, and multiple hooks matching the hanging rings are fixedly installed on the inner wall of the tunnel. The duct body is then stretched, and the hanging rings are connected to their corresponding hooks, thus fixing the duct body and preventing tearing. However, due to the complex environment inside the mine, the ventilation ducts are not very stable and may fall during use. Furthermore, the ducts may vibrate and rub during transport, causing wear and tear, reducing their lifespan and increasing the operating cost of the ventilation equipment. Summary of the Invention
[0003] To solve the above-mentioned technical problems, this utility model provides a mine ventilation duct hoisting frame that is easy to adjust according to actual conditions, reduces wear and vibration noise, and improves practicality.
[0004] This utility model discloses a mine ventilation duct hoisting frame, comprising a fixed base, a lifting adjustment component, a position adjustment component, a shock absorption component, and a mounting component. The fixed base is H-shaped, with fixing holes at its four corners. The lifting adjustment component is installed at the bottom of the fixed base, the position adjustment component is installed at the bottom of the lifting adjustment component, the shock absorption component is installed at the bottom of the position adjustment component, and the mounting component is installed at the bottom of the shock absorption component. During installation, expansion bolts pass through the fixing holes of the fixed base to fix the fixed base in the mine. The H-shaped fixed base increases the contact area with the mine wall, ensuring stability. The lifting adjustment component can adjust the installation height, suitable for the complex environment inside the mine. The position adjustment component can adjust the mounting position for convenient use. At the same time, the shock absorption component can buffer and absorb vibrations, reducing wear and vibration noise. The mounting component hoists the ventilation duct.

The bottom of the T-shaped sliders is connected to the mounting brackets. The two mounting brackets are arranged opposite to each other. Connecting seats are installed on the upper part of the mounting brackets. The connecting seats are connected to the bottom of the mounting plate by bolts. Adjusting grooves are formed on the side walls of the mounting brackets. Adjusting sliders are slidably installed in the adjusting grooves. Fixing bolts are provided on the adjusting sliders. A clamping arc plate is installed at the front end of the adjusting slider. The ventilation duct is placed at the bottom of the mounting bracket. The adjusting slider is pushed to drive the clamping arc plate to press against the ventilation duct, limiting the ventilation duct. The fixing bolts are tightened to fix the adjusting slider to ensure stability. The mounting bracket is pushed to move the T-shaped sliders in the T-shaped grooves to make fine adjustments to the mounting position, which is convenient for adjustment according to the actual situation and improves practicality.
