Abstract
Description
Technical Field
[0001] This utility model relates to the field of underground waterproof gate technology, and in particular to an upward-opening type waterproof gate support. Background Technology
[0002] Waterproof gates are crucial safety devices in underground mines, ensuring the safety of workers and protecting critical facilities such as pump rooms and central substations. To guarantee the pressure-bearing capacity of the waterproof gate, the gate leaf, as a key pressure-bearing component, is typically heavy. The gate leaf is usually kept open to ensure normal ventilation and transportation requirements in the roadway. For belt conveyor roadways, to avoid damaging the conveyor belt and to allow for rapid closure, upward-opening waterproof gates with hydraulic control systems are often used, using hydraulic cylinders to support the upward opening of the gate leaf. Due to internal leakage in the hydraulic system, the supporting force of the hydraulic cylinder gradually decreases, causing the gate leaf to slowly descend. In certain special circumstances, such as damage to the hydraulic pipeline leading to rapid depressurization of the cylinder, the gate leaf may fall rapidly, potentially causing personnel injuries, equipment damage, and ventilation disruptions, posing significant safety hazards. Furthermore, the hydraulic cylinder and the gate hinge are subjected to significant forces, which can easily lead to deformation of the hinge, shortening the service life of the waterproof gate.

Two cover side plates 405 are fixedly connected to the lower surface of the cover connecting plate 401, and a cover base plate 403 is fixedly connected between the two cover side plates 405. A V-shaped guide rail 402 is fixedly connected to the upper surface of the cover base plate 403, and the support rod 1 is slidably mounted on the V-shaped guide rail 402. The support rod 1 includes a support rod base plate 105, with both sides of the support rod base plate 105 fixedly connected to... A side sealing plate 107 is fixedly connected. The top of the two side sealing plates 107 is fixedly connected to an upper flat steel plate 103 and an upper inclined steel plate 104.

The V-shaped slider 106 is slidably connected to the V-shaped guide rail 402.
[0031] Working principle:
[0032] During use, two installation beams are installed at appropriate positions on the inlet side of the waterproof gate, with two sections of concrete pre-embedded at both ends of the installation beams. The connecting frame 3 is fixed below the installation beams via the installation connecting device 2. During installation, two installation steel plates 203 are placed above the installation beams and secured to the two installation connecting plates 301 on the connecting frame 3 with nuts 202 via double-headed studs 201. This installation method can avoid open-fire construction underground, especially in coal mines, and can reduce the corresponding construction risks.
[0033] The support rod cover 4 is fixedly installed below the connecting frame 3 near the waterproof gate. The cylinder support 6 is fixedly installed below the connecting frame 3 away from the waterproof gate. The support rod 1 is installed inside the support rod cover 4. The cylinder end of the hydraulic cylinder 5 is hinged to the cylinder support 6. The piston rod end of the hydraulic cylinder 5 is hinged to the tail of the support rod 1. The support rod 1 slides inside the support rod cover 4 by pushing and pulling the hydraulic cylinder 5.
[0034] After the door support is installed, once the waterproof gate leaf is fully opened, the hydraulic cylinder 5 pushes the support rod 1 to slide towards the edge of the gate leaf. The movement of the support rod 1 is detected by an inductive switch. When the support rod 1 reaches its final position, it automatically stops. The vertical distance between the gate leaf and the support rod 1 is 2cm-3cm. As the hydraulic system slowly leaks internally, the cylinder support becomes insufficient, causing the gate leaf to slowly fall. Alternatively, in the event of a sudden hydraulic line failure, the gate leaf may fall suddenly and contact the support rod 1. The support rod 1 then distributes the weight of the gate leaf, preventing it from falling further. This also reduces the stress on the hydraulic cylinder 5 and the gate hinge, preventing deformation of the gate hinge and the gate leaf, and extending the service life of the waterproof gate. When the gate leaf is fully opened, there is a 2cm-3cm vertical distance between the gate leaf and the support rod 1. The beveled design at the front of the support rod 1 effectively ensures the smoothness of the extension and retraction of the support rod 1, reduces the impact of a sudden fall of the gate leaf on the support, improves the reliability of the support, and provides safety for the waterproof gate equipment and personnel.
