The new transverse traveling vehicle travels on a track arranged on the ground. The transport direction of the transverse traveling carriage is perpendicular to the transport direction of the longitudinal traveling carriage 1. Two tracks matched with the tracks in the furnace, the kiln or the tank are distributed at the upper part of the transverse walking vehicle, the longitudinal walking vehicle 1 walks on the tracks at the upper part of the top of the transverse walking vehicle, and the walking direction of the longitudinal walking vehicle 1 is the direction of entering and exiting the furnace, the kiln or the tank. When the product needs to move longitudinally, the rail on the transverse traveling vehicle is aligned with the rail in the furnace, kiln or tank, the longitudinal vehicle can enter the furnace, kiln or tank along the rail, and after the specified technological process is completed in the furnace, kiln or tank, the longitudinal vehicle can move out along the rail, and the longitudinal traveling vehicle 1 is transported to the furnace, kiln or tank of the next technological process from the transverse traveling vehicle to wait for entering the next technological process.

Regarding the transverse walking vehicle, a plurality of R-shaped speed reducing motors are arranged on the transverse walking vehicle, the R-shaped speed reducing motors are directly connected with the wheels 4 of the transverse walking vehicle through a coupler, the use of a chain 12 in the prior art is replaced, and the synchronous rotation of the wheels 4 during starting and running is ensured.

The transverse traveling vehicle is provided with a chain 12 and a driving device 11 for driving the chain 12, and the necessary structural components such as a chain wheel and a tension wheel are not described in detail herein. The chains 12 are embodied as triple chains 12, i.e. three chains 12 are used side by side. This ensures that the chain 12 is not damaged when subjected to sufficient tension during transport. The chain 12 is arranged in a direction which coincides with the track direction traveled by the longitudinal running vehicle 1. The driving device 11 is a speed reduction motor provided at the rear of the transverse traveling vehicle. The tail refers to the end of the transverse walking vehicle away from the kiln.

The chain 12 is arranged below the longitudinal running vehicle 1 and between the two rows of wheels 4. A clamping element 9 is also arranged below the longitudinal carriage 1. The clamping part 9 is connected with the bottom plate 10 of the longitudinal walking vehicle 1 through bolts and clamps a plurality of sections of the chain 12, and when the chain 12 rotates, the longitudinal walking vehicle 1 is driven to walk on the guide rail. The forward and reverse rotation of the chain 12 effects the reciprocating motion of the longitudinal running carriage 1. In this way, the chain 12 and the drive means 11 will no longer enter the kiln, avoiding the transmission equipment to be attacked by high temperatures.

In addition, a plurality of teeth matched with the chain 12 are arranged on the clamping piece 9, so that the clamping piece 9 and the chain 12 can be guaranteed to be clamped, and slipping is avoided. Equally, the chain 12 can also be directly fixedly connected to the longitudinal carriage 1 by means of high-strength bolts.

As regards the structure at the wheels 4 of the longitudinal running carriage 1, a single-wheel single-axle design is used. Firstly, it should be mentioned that, the longitudinal main beam 3 of the longitudinal walking vehicle 1 adopts a box structure with a downward opening, and the wheels 4 are uniformly distributed in the longitudinal main beam 3, under such a design, the box can be filled with heat insulating materials if necessary, so that the ambient temperature environment of the parts can be effectively reduced, and the service lives of the parts can be effectively prolonged.

The lower part of the wheel 4 protrudes from the opening of the box. The wheel shaft 6 penetrates through the wheel 4 and is in rotary connection with the wheel 4, specifically, an oilless bearing 8 is arranged between the wheel shaft 6 and the wheel 4, and two ends of the oilless bearing 8 are also provided with shaft sleeves to limit the play of the oilless bearing 8. The wheel axles 6 extend from the longitudinal girders 3 at both ends. The welding has the shaft cardboard 5 on the outer wall of vertical girder 3, and every wheel 4 corresponds two shaft cardboards 5, and the both ends of shaft 6 and two corresponding shaft cardboard 5 fixed connection, and concrete structure is, has seted up opening 51 in the bottom of shaft cardboard 5, and during opening 51 was worn to locate by shaft 6, two draw-in grooves 61 have been seted up respectively at the both ends of shaft 6, and two draw-in grooves 61 are located the both sides that deviate from mutually of two shaft cardboards 5. A limiting plate 7 is arranged in the clamping groove 61, and the limiting plate 7 is fixedly connected with the wheel axle clamping plate 5 through bolts. The fixed limit plate 7 not only supports the wheel shaft 6, but also limits the rotation of the wheel shaft 6, and the wheel shaft 6 supports the wheel 4 in a rotating mode. The design replaces the existing design of using a tensioning sleeve, can resist high temperature in a kiln, has independent supporting structures of wheels, is convenient to disassemble and maintain, has low maintenance cost in the later period, simplifies the structure, saves materials, lightens the vehicle weight, and most importantly eliminates the phenomenon that the wheels 4 slip and do not rotate after the oilless bearing 8 is adopted. It is to be noted that a pin-type structure may be used at the wheel 4 instead of the above-mentioned structure of the wheel axle 6.
