Description

Quick-dismantling movable track for underground waterproof door

Technical Field

The utility model relates to a mechanical device especially relates to a mine has rail transportation lane water proof door department can dismantle mechanical device fast.

Background

The movable rail and the fixed rail at the waterproof door of the existing underground rail transportation roadway are usually connected in a rail clamping plate mode, namely the movable rail and the fixed rail are respectively fixed with the rail clamping plate by bolts and nuts to achieve the purpose of connecting the movable rail and the fixed rail.

The accident of permeating water takes place in the pit, under the urgent condition of flood control, at the in-process of closing the water proof door, need demolish the movable track of water proof door department, demolish the movable track more difficult under the existing condition, especially when screwing up the nut, it is longer to consume time, seriously influences flood control safety. Therefore, it is a technical problem to be solved at present to design a movable rail capable of being disassembled quickly.

Disclosure of Invention

In order to overcome the defect that the time consumed for dismantling the movable track at the waterproof door is long in the prior art and solve the problem that the movable track is difficult to dismantle when the waterproof door of the underground rail transportation roadway needs to be closed quickly, the quick-dismantling movable track at the waterproof door of the underground transportation roadway is designed.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a waterproof door quick detach formula movable rail in pit, mainly by the activity rail, fixed rail, angle steel triangular support, bolt, nut, round pin axle, split pin and steel sheet constitute, its activity rail is two, two activity rail parallel arrangement, the rail bottom is cut into the width the same with the rail waist respectively to activity rail both ends and fixed rail one end, and has two bolt holes on the rail waist, places two steel sheets respectively at the both ends of two activity rails, and fixes firmly with the tunnel bottom plate.

The quick-dismantling movable track for the underground waterproof door comprises eight angle steels, wherein each angle steel is provided with four bolt holes as large as those in the track waist, the eight angle steels are divided into four groups and are respectively fixed on the two steel plates, two groups of angle steels are arranged on each steel plate, each group of angle steels are fixed on the steel plates in a back-to-back mode, the gap between the angle steels is slightly larger than the width of the track waist, the axial direction of the angle steels is consistent with the axial direction of the track, and each angle steel is provided with two angle steel three-foot supports for reinforcing the angle steels.

The two ends of the two parallel movable rails and one end of the fixed rail are respectively inserted into the gap between the angle steels, then the movable rails are fixed by the pin shafts and the split pins through the bolt holes of the angle steels and the rails, and the fixed rails are fixed by the bolts and the nuts through the bolt holes of the angle steels and the rails.

The beneficial effects of the utility model are that, when taking place the accident of permeating water in the pit, when needing to close the water proof door, only need get two round pin axles and the split pin at activity track both ends, need not to unload the nut and the bolt of fixed track, just can remove the activity track, close the water proof door, saved the time, solved in the pit rail transportation tunnel water proof door and closed slow problem, flood control safety has ensured.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

A quick-dismantling movable track for an underground waterproof door mainly comprises two movable tracks 2, two fixed tracks 1, two angle steels 3, an angle steel triangular support 4, bolts 11, nuts 12, pin shafts 9, split pins 10 and steel plates 7, wherein the two movable tracks 2 are arranged in parallel, the bottoms of the two movable tracks 2 and one end of the fixed track 1 are respectively cut into the width same as the width of a track waist (as shown in figure 7), the track waist is provided with two bolt holes 8 (as shown in figure 5), the two steel plates 7 are respectively placed at the two ends of the two movable tracks 2 (as shown in figure 1, a support A and a support C share one steel plate, and a support B and a support D share one steel plate), and are fixedly fixed with a roadway bottom plate.

The utility model discloses a total eight angle steel 3, there are four bolt holes 8 as big as on the web of rail on every angle steel 3, divide into four groups of eight angle steel 3 and fix respectively on two

steel sheets

7, 7 two sets of angle steel 3 of every steel sheet, every group angle steel 3 all fixes on steel sheet 7 back to back, the clearance is a little bigger than the width of rail web of rail between the angle steel 3, and the axis direction of angle steel 3 is unanimous with rail axis direction, there are two angle steel tripod supports 4 to be used for consolidating angle steel 3 on every angle steel 3 (as shown in figure 4).

Two ends of two parallel movable rails 2 and one end of a fixed rail 1 are respectively inserted into gaps between angle steels 3, then the movable rails 2 are fixed by pin shafts 9 and cotter pins 10 through the angle steels 3 and bolt holes 8 of the movable rails 2, and the fixed rails 1 are fixed by bolts 11 and nuts 12 through the angle steels 3 and bolt holes 8 of the fixed rails 1.

When the watertight door 5 needs to be closed: firstly, the cotter pins 10 and the pin shafts 9 at the two ends of the two movable rails 2 are removed; (II) four people lift the two movable rails 2 to a place where the closing of the waterproof door is not influenced; and (III) closing the waterproof door. Thereby, the waterproof door is closed quickly.
