Abstract

PURPOSE:To connect an exhaust gas discharging hose to a vehicle and move in automatically synchronously with the moving speed of a conveyer by using a conveyer pit, in which a conveyer for transportation of a vehicle test is installed, as a horizontal gas-discharging duct. CONSTITUTION:A vehicle is transported along a conveyer pit P formed in a lower part of a vehicle inspection line-booth Q. One end of a gas discharging hose 8 is attached to an engine exhaust-gas discharging part (muffler, etc.) of a vehicle which is put on a conveyer 2 and moved under the driving conditions and at the same time the other end of the gas discharging hose 8 is pushed in a cut of a conveyer gas- discharging outlet seal formed in the conveyer 2 and inserted into a gas discharging hose setting inlet 5, so that the exhaust gas of the engine is discharged to air or a proper gas cleaning apparatus out of a gas discharging duct 7 by a sucking force of a gas discharging fan 6 through an exhaust gas passing route which uses the conveyer main body as a horizontal duct. As a result, since a exhaust gas discharging hose transporting wire 9 and the conveyer 2 move synchronously at the same speed, the hose returns to the starting of the conveyer 2 and can be attached to the next vehicle and used.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an exhaust gas discharge device for discharging to the outside air exhaust gas discharged during engine adjustment or testing on a production and inspection line for automobiles and the like.

Conventionally, on automobile production lines or test lines, multiple suction hoods installed near the muffler approach the exhaust gas emitted from the muffler, and the suction hoods collect the exhaust gas just before it is dispersed into the air, and a blower fan is used to collect the exhaust gas. It was vented to the outside air. In this type of system, since the intake hood cannot follow the moving vehicle, a considerable portion of the exhaust gas is dissipated into the air, and the concentration of exhaust gas in the air inside the building surrounding the line gradually increases, making it unsuitable for use as a work space. There was a risk that it would be inappropriate.

In addition, an exhaust system is used in which an exhaust duct with rails is installed above the conveyor on which the vehicle moves, and an exhaust hose that can be moved by a trolley is connected to this exhaust duct. A hose must be connected to the vehicle's muffler and exhaust gas exhaust work must be carried out while synchronizing the movement of the trolley with the movement of the line.

In any case, with the conventional method, relatively complicated equipment that occupies a considerable amount of space is attached to the existing line, requiring a great burden of installation and operation, and even during operation, it obstructs the work of the workers. There were many problems such as.

The present invention solves these problems and makes it possible to achieve effective air purification with a simplified system. Therefore, the present invention includes a vehicle transfer conveyor provided in a conveyor pit below the inspection line booth, an exhaust hose transfer device provided along the conveyor, and an exhaust hose mounted on the exhaust hose transfer device. The present invention is characterized by an exhaust gas discharging device for a vehicle inspection system in which a conveyor belt is provided with an exhaust hose centro and the conveyor is configured as a horizontal duct for exhaust discharge over almost the entire length of the conveyor. In this case, the conveyor is characterized in that it has a central exhaust hose on the upper surface of the conveyor belt, and that the side surface is covered by a conveyor side cover and the bottom surface is covered by a conveyor bottom cover.

It is also an exhaust gas exhaust device characterized by having an exhaust pit attached to the side of the conveyor pit, and an exhaust duct that communicates with the atmosphere via an exhaust fan installed at the exhaust pin.

Embodiments of the above-described apparatus will be described in detail below with reference to the accompanying drawings. The discharge device 1 according to the present invention includes a conveyor 2 through which vehicles are transferred along a conveyor pit P provided at the bottom of an inspection line booth Q for vehicles, etc., and a conveyor 2 made of heat-resistant material such as Teflon along the conveyor 2 It consists of an exhaust hose conveying device 3 that is movable while suspending a plurality of exhaust hoses.

The conveyor 2, which occupies a part of the conveyor pit P space, has a conveyor belt 9 on the top surface, a conveyor side cover 15 on both sides, and a conveyor bottom cover 16 on the bottom surface.
This constitutes a long, slender, cylindrical underground exhaust duct.

As is clear from FIG. 1.2, conveyor exhaust hose set ports 5 are provided at predetermined intervals in the bell 9 of the conveyor 2, and the exhaust hose set ports 5 are covered by a conveyor exhaust port seal 20. The exhaust port seal 21 is made of a rubber seal that has a cut 22 inserted therein, and when the tip of the exhaust hose 8 is inserted, it splits downward and is received into the exhaust hose set port.

The conveyor 2 is driven by a motor 4 in the direction of the arrow in FIG.

An exhaust pit 17 is provided on the side of the conveyor pit P, and as shown in FIG. 4, the upper surface of this exhaust pit H7 is covered with a pit cover 18. As is clear from FIG. 1.3, an exhaust duct 7 is installed in communication with the exhaust focus via an exhaust fan 6.

The exhaust hose conveying device 3 has a wire drive motor 10, a wire drive roller 11, a tensicon roller 13, and a wire guide 12 fixedly attached to a suitable structural member, and an exhaust hose conveyor wire 9 is hung between both rollers and the wire guide. A hook attached to the exhaust hose 8 is hooked onto a wire 9 so that the hose 8 can be moved along the conveyor 2. When the hose 8 returns to the starting end of the wire, it is fixed by the hose 7 par 14 regardless of whether the wire 9 is driven.

The device of the present invention configured as described above attaches one end of the exhaust hose 8 to an engine exhaust discharge part (such as a muffler) from a moving vehicle placed on the conveyor 2 in an operating state, and also attaches the other end of the exhaust hose 8 to the engine exhaust discharge section (muffler, etc.). By pushing the end into the cant 22 of the conveyor exhaust port seal 20 provided on the conveyor 2 and inserting it into the exhaust hose set port 5, the engine exhaust passes through an exhaust path with the conveyor body as a horizontal duct and is sucked into the exhaust fan 6. The power is discharged through the exhaust duct 7 to the atmosphere or to a suitable cleaning device. Therefore, at the end of the test time, if the exhaust hose 8 is removed from the Centro 5, removed from the vehicle, and suspended on the exhaust hose transfer device 3, the exhaust hose transfer wire 9 and the conveyor 2 will move in synchronization at the same speed. Therefore, it returns to the starting end of conveyor 2 and is used for mounting on the next vehicle.

As described above, the exhaust gas evacuation device according to the present invention utilizes the conveyor pit in which the vehicle test transport conveyor is installed as a horizontal exhaust duct, so that the exhaust hose is automatically moved in synchronization with the moving speed of the conveyor. connection to and movement of vehicles. In addition, the exhaust system is configured with a horizontal duct housed in a part of the conveyor focus, so inspectors and workers can use the above-ground space without having to occupy a large-volume duct along the conveyor in the above-ground work space. can create an environment where it is easy to operate.
