Description
Technical field
It keeps off a car safety device the utility model relates to a kind of pneumatic gate-type of underground coal mine, is power source using underground pressure air,
Utilize the opening and closing of Telescopic-cylinder control vehilce-blocking door.
Background technique
Underground rails of coal mine needs installation settings alley stopping device when transporting large scale equipment, for preventing derailing accident, really
Protect transportation safety.Current alley stopping device is made of right doorframe, left doorframe, vehilce-blocking door etc., is consolidated the vehilce-blocking door left side using hinge
It is fixed to be arranged in left doorframe, it is ridden in right doorframe on the right of vehilce-blocking door, which is opened and closed manually by signal cager.This structure side
There are two hidden danger for formula: first is that signal cager can not hide in time, and personnel casualty accidents is caused to be sent out when sport car occurs for vehicle
It is raw；Second is that wirerope has crossed vehilce-blocking door when winch towing vehicle, it need to be across steel wire when signal cager is opened and closed vehilce-blocking door
Rope, the unexpected stress of Yi Fasheng wirerope or fracture cause injury to personnel accident to occur.
Utility model content
The mesh of the utility model is to provide the pneumatic gate-type in underground that a kind of cager is easy to operate, safe and reliable and keeps off a car insurance
Device.
To achieve the above object, the utility model includes: right doorframe, vehilce-blocking door, left doorframe, hinge, operation valve, cylinder,
The vehilce-blocking door left side is fixed in left doorframe using hinge, is ridden in right doorframe on the right of vehilce-blocking door, the pedestal of cylinder is fixed
The lower part of left doorframe is set, and the piston end of cylinder is connect with the following side of vehilce-blocking door, is connected to cylinder using high-pressure rubber pipe
The air inlet of operation valve, operation valve is connected to the air line of underground coal mine.
Signal cager can control at a distance Telescopic-cylinder with manipulation operations valve in this way, when cylinder piston end is stretched out, push away
Dynamic vehilce-blocking door is opened, and vehicle can be with safety；When cylinder piston end is withdrawn, traction vehilce-blocking door is closed, for preventing vehicle
Accident occurs for sport car, effectively ensures the personal safety of operator.Have the characteristics that easy to operate, safe and reliable.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the left view of the utility model structure diagram.
Specific embodiment
As seen from Figure 1, Figure 2, the utility model includes: right doorframe 1, vehilce-blocking door 2, left doorframe 3, hinge 4, operation valve 6, gas
Cylinder 8.2 left side of vehilce-blocking door is fixed in left doorframe 3 using upper and lower two hinges 4, rides over right doorframe on the right of vehilce-blocking door 2
On, vehilce-blocking door can be rotated around hinge, and vehilce-blocking door uses mining channel steel processing and fabricating, guarantee that its is solid and reliable.Right doorframe 1 with
Left doorframe 3 is processed into triangle using mining channel steel, and its underpart is embedded in tunnel bottom both sides, solid and reliable to guarantee.Gas
The pedestal of cylinder 8 is fixed at the lower part of left doorframe 3 and is connected thereto securely, the piston end of cylinder 8 and the following side of vehilce-blocking door
Connection, is connected to operation valve 6 for cylinder using high-pressure rubber pipe 5, the air inlet of operation valve is connected to the air line of underground coal mine
7, cylinder, operation valve, high-pressure rubber pipe are all made of mining model, to meet underground coal mine use condition.The specification of the utility model
Series of products can be made according to drift section size in size.
