Background technique

In many cases, it is necessary to use rails to transport heavier items. In the case of brick factories, it is necessary to use the rails to transport the prepared bricks to the kiln for firing, but there are many places for making bricks, and there is only one brick kiln. Therefore, how to use the track to transport brick kiln from multiple locations to the brick kiln is a difficult problem. If each slab is constructed with a straight track that passes through the brick kiln, there will be problems of rail crowding and high cost, and the narrow brick kiln also Can not accommodate multiple tracks leading to the interior.

The invention of the patent No. 201320833454.8 discloses a rail conveying device comprising at least two source tracks and a target track, the source track and the target track being arranged in parallel, further comprising a transport track perpendicular to the source track, the source The rails and the target rails are respectively located at two sides of the transport rail, and the transport rail is provided with a transfer platform that can travel along the transport rail, and the transport platform is provided with an auxiliary rail parallel to the source rail, the source rail, The target track and the auxiliary track are on the same plane; the two-way track conveying device further includes a rail car that can travel on the source track, the target track, and the auxiliary track. In the above-mentioned rail conveying device, when the rail car travels to the transfer platform, the rail car can be propelled in one direction by using a structure such as a cylinder and a corresponding pushing plate, and if the rail car is required to travel in the opposite direction, it can only rely on manpower. Pushing requires more manpower.

Summary of the invention

SUMMARY OF THE INVENTION It is an object of the present invention to provide a two-way rail transport apparatus that can transport items at a plurality of locations to the same destination through as few tracks as possible, and can save manpower.

The bidirectional rail conveying device of the present invention comprises at least two source rails, one target rail and one transport rail perpendicular to the source rail, the source rail and the target rail are arranged in parallel, and the source rail and the target rail are respectively located at two of the transport rails. On the side, the transfer track is provided with a transfer platform that can travel along the transfer track, and the transfer table is provided with an auxiliary track parallel to the source track, and the source track, the target track and the auxiliary track are on the same plane; The bidirectional rail conveying device further includes a railcar that can travel on the source rail, the target rail, and the auxiliary rail; the key is that the transporting station is provided with a carrier, a gear that is movably mounted on the carrier through the rotating shaft, and a driving gear transmission. a driving mechanism, the carrier is mounted on the transfer table by a resilient jacking mechanism, the top of the gear is exposed on a top surface of the transfer table; the rail car is provided with a strip belt parallel to the auxiliary rail, the strip belt A perforation is provided for mating with the gear.

The principle of the above two-way rail conveying device is as follows: First, the rail car is stopped on the source rail, and the auxiliary rail on the transport platform is aligned with the source rail where the rail car is located, and the source rail and the auxiliary rail are integrally connected; In the railcar, the railcar is then pushed along the source track to the auxiliary track of the transfer platform, and then the transfer platform is pushed along the transfer track to the target track, the auxiliary track is aligned with the target track, and finally the rail car is pushed from the auxiliary track to On the target track, the transport from the source track to the target track is completed. In this way, only one target track and transport track need to be built, and the goods of multiple source tracks can be transported to the destination, which saves the investment and space occupied by the track.

In addition, when the rail car travels to the transfer platform, the perforations on the rail car strip mesh with the gears on the transfer table, and the drive mechanism drives the gears to rotate, thereby driving the rail car to travel along the auxiliary track, thereby saving Manpower. In addition, the rail car does not need to be additionally equipped with a power unit, which saves costs.

When the strip contacts the gear, the gear is pressed down and the resilient top mechanism provides the gear with an upward spring force so that the gear can snap into the perforations of the strip. If there is no elastic topping mechanism, if the gear position is set too high, it will interfere with the strip belt, causing damage. If the gear position is set too low, it will not be caught in the perforation of the strip belt, and the driving function cannot be realized.

Specifically, the jacking mechanism includes a top post, a sleeve and a spring, and the bottom end of the top post is fixedly connected to the transfer table by a bracket, and the sleeve is sleeved on the top post, and the top end of the sleeve is fixed to the carrier The spring sleeve is sleeved on the sleeve and the top post, and the bottom end of the spring abuts the bracket, and the top end of the spring abuts the carrier. The sleeve and the top post cooperate to achieve guiding to avoid horizontal sway of the carrier; the spring can provide an upward lifting force for the carrier to drive the gear to move upward.

Specifically, the driving mechanism is composed of a tensioning wheel, a driving motor and a chain, and the driving motor is fixed on the transfer table, and the chain is closed between the motor shaft of the driving motor, the tensioning wheel, and the rotating shaft of the gear. . The tensioning wheel ensures that the chain is always tensioned to prevent the chain from falling or slipping.

Further, the end faces of the source track and the target track are provided with grooves having an opening direction toward the transport track, and the groove walls on both sides of the groove are inclined faces, so that the groove has a tapered trumpet shape. The transfer table is fixed with a hydraulic cylinder, and the piston rod of the hydraulic cylinder is connected with a positioning bolt facing the groove, and the end shape of the positioning bolt is adapted to the shape of the groove. When the transfer station travels on the transfer track and is close to the source track or the target track, the positioning pin will also move synchronously to the vicinity of the groove with the transfer table. When the auxiliary track is quickly aligned with the source track or the target track, the piston of the hydraulic cylinder is controlled. When the rod is extended, the positioning bolt will protrude into the groove. Since the cross section of the groove is a tapered bell mouth shape, the groove wall of the inclined surface will force the positioning pin to align the groove, that is, the auxiliary track is aligned with the source. The track or target track ensures that the auxiliary track is correctly connected to the source track or the target track. After the transfer is completed, the hydraulic cylinder can be controlled When the piston rod is retracted, the positioning bolt will come out of the groove, so that the transfer table can continue to travel along the transport track.

Further, the gear is located in the middle of the auxiliary rail, and the strip is disposed at the bottom of the rail car, so that the safety hazard caused by the exposure of the gear can be avoided.

The bidirectional rail conveying device of the present invention can transport articles of a plurality of locations to the same destination through as few or fewer tracks as possible by providing a transport rail and a transfer station, and only need to provide a power system on the transfer platform, without The power system is set on the rail car, which not only promotes the manpower, but also saves the investment and space occupied by the track, and has good practicability.
