Description

Technical Field

[0001] The present invention relates to the field of mine underground safety equipment, and particularly to a waterproof gate in a track roadway. Background Art

[0002] When a water inrush disaster occurs in a mine, it usually has the characteristics of large water inflow and fast spreading speed. When a water inrush accident occurs, it is necessary to quickly close the waterproof gate to isolate the mine in sections, narrow the scope of the disaster impact, control the harm of the water potential, and ensure the safety of the mine.

[0003] For the waterproof gate arranged in the track roadway, currently the tracks are all laid above the lower door frame of the waterproof gate, which affects the closing of the waterproof gate. Before closing the waterproof gate, it is necessary to remove the tracks and their affiliated facilities that affect the operation of the waterproof gate to ensure the normal operation of the waterproof gate. At present, the work of removing the tracks at the waterproof gate is mostly manual operation. Under the state of the waterproof gate closing drill, it takes more than 40 minutes for manual operation to complete this work. In case of a disaster, the time required for removal is even longer, which is extremely unfavorable to the safety of personnel and the mine. Subsequently, a variety of devices for automatically removing the tracks at the waterproof gate have emerged one after another, which can better complete the removal of the tracks at the waterproof gate. To ensure that the tracks can be automatically removed in time, the tracks on the device are not tightly connected to the on-site tracks, which has a certain adverse impact on the on-site tracks; the device needs to be regularly overhauled and maintained; regular operation tests are required to ensure reliable performance; long-term locomotive operation may cause the device to shake and lead to derailment accidents of the locomotive.

[0025] The door leaf 3 is rotatably arranged on the doorframe 1.

[0026] And the track sealing door panel 5 is slidably arranged along the vertical direction on the water-facing side of the door leaf 3. When the door leaf 3 is in the closed state, the track sealing door panel 5 descends to the lowest point and seals the gap between the bottom of the door leaf 3, the doorframe 1 and the steel rails 135 to complete the sealing. An oil cylinder 6 for driving the track sealing door panel 5 to lift and lower is arranged on the door leaf 3.

[0027] Embodiment 2, as Figures 1-4 shown, a waterproof gate for a track roadway proposed by the present invention. Compared with Embodiment 1, the structure of the doorframe 1 is introduced in detail in this embodiment.

[0028] The doorframe 1 is a welded structural member, including an upper cross beam 11, two columns 12 and a bottom cross beam 13. According to the transportation requirements, it can be made into a split type and assembled at the installation site in a way of being connected by fasteners. The upper cross beam 11 and the columns 12 are both welded by a bottom plate 111, a web plate 112, a rib plate 113 and a wing plate 114. Specifically, the top of the web plate 112 is welded to the wing plate 114, and the bottom is welded to the bottom plate 111 to form a long strip structure with an I-shaped cross section. The rib plates 113 are respectively welded to the bottom plate 111, the web plate 112 and the wing plate 114 to increase the overall stiffness and prevent deformation. The bottom cross beam 13 is welded by a beam 131, a bottom cross beam rib plate 132, a bottom cross beam wing plate 133, a wing plate rib plate 134, a middle cross beam inclined sealing plate 136, a middle cross beam sealing plate 137, a steel rail side sealing plate 138 and an end sealing plate 139. The wing plates 114 of the upper cross beam 11 and the two columns 12, as well as the bottom cross beam wing plate 133, all form a tapered structural ring beam at an angle of 45° with the center line of the doorframe 1. The cross sections of the upper cross beam 11 and the two columns 12 are both I-shaped structures, and the bottom plate 111 is relatively wide and is installed and embedded in the chamber 9, which can effectively reduce the load borne by the concrete around the bottom plate. A column bottom plate 121 is arranged on the outside of the column 12, and a door pivot 2 is arranged on the column bottom plate 121. The door pivot 2 adopts a design of a rolling bearing installed inside the support and an outer extending shaft head, and is fixed on one side of the column bottom plate 121 by fasteners. A connecting piece 4 is rotatably arranged on the door pivot 2. Specifically, the connecting piece 4 is of a fork-shaped structure. The outer extending shaft head on the door pivot 2 is rotatably connected with one end of the connecting piece 4 in a way of tight fit between the shaft and the hole in the vertical direction. Door leaf connecting seats 36 are arranged at both the upper and lower ends of the outer side of the door leaf 3. The other end of the connecting piece 4 is rotatably connected with the door leaf connecting seat 36. After installation, there is a 10-mm moving gap. After the door leaf is closed, under the action of water pressure, the door leaf 3 can translate 7 mm along the water pressure direction, further compressing the door leaf sealing strip 33 to achieve a better sealing effect. The outer extending shaft head of the door pivot 2 can rotate 360°, which can ensure any opening angle of the waterproof gate.

[0029] Further, the cross beam 13 has the beam 131 as the main body. The beam 131 can be a welded structure or made of suitable profiles. The bottom cross beam rib plate 132 is welded on the beam 131 to improve the overall strength and stiffness. The top surface of the rail 135 is flush with the upper plane of the beam 131. The lowest edge of the ring beam is higher than the top surface of the rail 135 and lower than the top surface of the bottom cross beam wing plate 133. The bottom cross beam wing plate 133 is arranged on the top of the beam 131 and includes two sections, which are respectively located outside the two rails 135. The wing plate rib plate 134 is connected to both the top of the beam 131 and the bottom cross beam wing plate 133. A corresponding groove is provided on the inner side of the rail 135 for the ore wheel to ensure the smooth passage of the ore car. In the area between the two rails 135, the backwater side of the top surface of the beam 131 is flush with the top surface of the rail 135, and a middle cross beam sealing plate 137 is welded on the water inlet side to form a height difference with the top surface of the rail 135. And a middle cross beam inclined sealing plate 136 is welded in this area to meet the sealing and guiding requirements of the back surface of the track sealing door panel 5. Inclined rail side sealing plates 138 are arranged on both sides of the rail 135 to meet the sealing and guiding requirements of the track sealing door panel 5 and both sides of the rail 135. The end sealing plates 139 are welded to the bottom cross beam wing plate 133, the beam 131 and the middle cross beam sealing plate 137 respectively. The end sealing plates 139 are arranged in an inclined structure to meet the guiding and sealing requirements of both sides of the track sealing door panel 5 and the bottom cross beam wing plate 133.

To ensure the overall strength and stiffness of the door leaf, a reinforcing steel plate 37 needs to be welded at the disconnected position of the door leaf 3, and a sealing strip is arranged at the corresponding position where the reinforcing steel plate 37 needs to be sealed; the door leaf sealing strip 33 is arranged along the girt 32 and forms a closed loop with the sealing strip arranged on the reinforcing steel plate 37 to ensure that there is no water leakage point between the girt 32 and the girt of the doorframe; the door leaf rib plates 31 are arranged on the water-receiving side of the door leaf 3 and are arranged longitudinally and transversely, and are respectively welded to the shell plate 35, the girt 32, and the reinforcing steel plate 37 to improve the overall strength and stiffness of the door leaf 3; the door leaf connection seat 36 is welded to the shell plate 35; the guide wheel mounting seat 34 is welded to the girt 32 and the door leaf rib plates 31.

[0032] Embodiment 4, as Figure 1 , Figure 4 and Figure 5 shown, a waterproof gate for a track roadway proposed by the present invention. Compared with Embodiment 3, the structures of the guiding device 8 and the track sealing door panel 5 are introduced in detail in this embodiment.

[0033] The guiding device 8 includes a guide wheel assembly 81 and a guide rail 82; the guide wheel assembly 81 is an assembly, including a concave V-shaped guide wheel, which has a rolling bearing, a shaft, and protective covers, fasteners, etc. required for installation inside. The shaft is a single-sided extended structure. The concave V-shaped guide wheel can rotate around the shaft. One end of the shaft is flush with the top surface of the guide wheel, and the other end extends out of the bottom surface of the guide wheel. The surface of the extended part of the shaft is finely processed, and the end is processed with threads; the shaft of the guide wheel assembly 81 is tightly fitted and installed in the hole on the guide wheel mounting seat 34, and the shaft end is fastened with a nut. The guide rail 82 is a convex V-shaped strip structure and is installed on both sides of the sealing plate 52 of the track sealing door panel 5 with fasteners. The convex V of the guide rail cooperates with the concave V of the guide wheel. During operation, the guide rail moves up and down with the sealing door panel, and the guide wheel rotates around the shaft. Each guide rail 82 is equipped with two guide wheel assemblies 81 to ensure that the guide rail does not disengage from the guide wheel during operation.

[0034] The track sealing door panel 5 includes a sealing strip 51, a sealing plate 52, a door panel rib plate 53 and an oil cylinder ear seat 54; the sealing plate 52 is made of thick steel plate, and the two sides below are inclined structures, and the inclination coincides with the end sealing plate 139 on the bottom cross beam 13. Above the rail 135 at the bottom of the sealing plate 52, corresponding U-shaped notches are provided. The two sides of the U-shaped notches are made into a V shape according to the side sealing plate 138 of the rail, which is beneficial to guiding and sealing at the track; the sealing strip 51 is installed in the U-shaped notches below and on both sides of the sealing plate 52; the door panel rib plate 53 is welded to the sealing plate 52 to improve the overall strength of the track sealing door panel 5; the oil cylinder ear seat 54 is welded to the middle of the upper part of the sealing plate 52.

The oil cylinder support 7 is a welded part and is installed on the water-receiving side of the door leaf 3 with fasteners. The position of the oil cylinder support 7 can be adjusted as required.

[0035] In summary, when the present invention is in use, when the waterproof gate is installed, except for the door frame ring beam of the door frame 1 and the part above the rail surface of the rail 135 in the bottom cross beam 13, the whole is buried in the chamber concrete. Both ends of the rail 135 are connected to the on-site track with standard rail connectors, and the door leaf 3 is in the normally open state. When it is necessary to close the waterproof gate, control to close the door leaf 3. After the door leaf 3 is closed in place, control the oil cylinder 6 to extend, push the whole track sealing door panel 5 to move downward, so that it fits tightly with the corresponding part of the bottom cross beam 13 to achieve the sealing effect. When opening the door, control the oil cylinder 6 to retract, pull the whole track sealing door panel 5 to move upward. After the bottom surface of the track sealing door panel 5 is higher than the rail surface of the rail 135, control to open the door leaf 3 to complete the door opening. Whether the door leaf 3 is closed in place and started in place, and whether the track sealing door panel 5 is sealed in place and retracted in place are all detected by induction switches. Each action is interrelated and sequential, which can avoid equipment damage caused by action disorders.

[0036] The embodiments of the present invention have been described in detail above with reference to the drawings, but the present invention is not limited to this. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art.
