Description

Technical Field

[0001] The utility model relates to a supporting device for a large wood heat treatment kiln, in particular to a kiln car transfer device for transporting a kiln car loaded with wood into the kiln body or transferring it from the inside of the kiln body to other places. Background Art

[0002] In order to quickly load or unload wood into or from a large wood heat treatment kiln, the whole kiln car needs to be used for transportation. In the prior art, an external track connected to the kiln car track inside the kiln body is mostly laid outside the kiln body corresponding to the kiln door position. This fixed external track cannot move. One wood heat treatment kiln corresponds to one external track and one kiln car, and a large site is required to meet the operation requirements. Moreover, the kiln car needs to complete the unloading of wood on the external track and then be loaded, resulting in a long empty kiln time, which is not conducive to improving the utilization rate of the heat treatment kiln. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a kiln car transfer device for a wood heat treatment kiln. This kiln car transfer device can conveniently send a heavy-load kiln car into the kiln or move it out of the kiln without laying a fixed track outside the kiln body. Moreover, the movement of the kiln car transfer device outside the kiln body is not restricted by a fixed track, and one kiln car transfer device can meet the kiln car transfer operation requirements of multiple wood heat treatment kilns.

[0004] The technical solution adopted to solve the technical problem: A kiln car transfer device for a wood heat treatment kiln includes a kiln car transfer vehicle arranged outside the kiln body. A plurality of universal walking wheels are provided at the bottom of the kiln car transfer vehicle. An external track capable of docking with the kiln car track inside the kiln body is provided on the kiln car transfer vehicle. A tractor capable of walking on the external track is provided on the external track. A plurality of walking track wheels cooperating with the external track are provided at the bottom of the tractor. A driving motor and a speed reducer are provided inside the tractor body. A traction gear is installed on the power output shaft of the speed reducer. A straight rack meshing with the traction gear is fixed along the length direction of the vehicle body on the kiln car transfer vehicle. An anti-jumping tooth mechanism for preventing the traction gear from jumping teeth during the meshing process with the straight rack is further provided on the tractor. The anti-jumping tooth mechanism includes a suspension fixed to the bottom of the tractor. An inverted F-shaped wheel frame is installed on the suspension. An anti-jumping wheel shaft and an anti-jumping wheel are installed on the wheel frame. The anti-jumping wheel is a horizontally rotating horizontal track wheel. The wheel rim of the horizontal track wheel is located below the tread surface. The tread surface of the horizontal track wheel is in rolling friction cooperation with the side wall of the straight rack base body. The upper surface of the wheel rim of the horizontal track wheel is in sliding friction cooperation with the bottom surface of the straight rack base body.

[0005] As a further improvement of the present invention: an anti-slip wheel is provided at the bottom of the tractor corresponding to each traveling track wheel, and the anti-slip wheel is installed at the rail waist of the outer track through a traveling wheel frame close to the wheel rim side of the traveling track wheel, the wheel axle of the anti-slip wheel is parallel to the wheel axle of the traveling track wheel, and the projection of the anti-slip wheel and the rail head of the outer track on the horizontal plane partially overlaps.

[0006] As a further improvement of the utility model: a plurality of stabilizing pillars are arranged at the bottom of the kiln car transfer vehicle, and an adjusting foot capable of adjusting the length of the pillar is arranged at the bottom of each stabilizing pillar.

[0007] As a further improvement of the utility model: a vertically pluggable positioning lock pin is provided at the bottom of the kiln car transfer car body on the side docking with the kiln car track, and a positioning lock hole matching the positioning lock pin is provided on the surface outside the kiln body.

[0008] As a further improvement of the utility model: a docking plug protruding from the end surface of the outer rail is provided on the rail head at the docking end of the outer rail, and a docking slot movably plugged with the docking plug is provided on the rail head at the docking end of the kiln car rail.

[0009] Beneficial effects: For the kiln car transfer device for wood heat treatment kiln of the present utility model, since the kiln car transfer device includes a kiln car transfer vehicle arranged outside the kiln body, universal walking wheels are provided at the bottom of the kiln car transfer vehicle, an outer track capable of docking with the kiln car track inside the kiln body is provided on the kiln car transfer vehicle, a tractor capable of walking on the outer track is provided on the outer track, and a plurality of walking track wheels cooperating with the outer track are provided at the bottom of the tractor. During use, the tractor pulls the kiln car in the kiln body onto the outer track of the kiln car transfer device, or pushes the kiln car on the outer track into the kiln body, thereby realizing the rapid loading and unloading of wood. Moreover, when the kiln car is transferred outside the kiln body, it is not restricted by a fixed track, and the kiln car can be conveniently transported to a designated location. One kiln car transfer device can meet the usage requirements of multiple wood heat treatment kilns. Since the way of meshing the traction gear with the straight rack is adopted to drive the tractor, and an anti-jumping tooth mechanism for preventing the traction gear from jumping teeth during the meshing process with the straight rack is also provided on the tractor, the traction capacity of the kiln car transfer device for wood heat treatment kiln of the present utility model is stronger, and it can meet the requirements of transferring large kiln cars of large wood heat treatment equipment. Since the technical feature that a wheel anti-disengagement device is provided at the bottom of the tractor corresponding to each walking track wheel is adopted, the anti-derailment ability of the tractor is increased, so that the kiln car transfer device for wood heat treatment kiln of the present utility model has better stability during the traction and transfer process of large and heavy kiln cars and will not have derailment accidents. Since the technical feature that a plurality of stable support columns are provided at the bottom of the kiln car transfer vehicle and adjustable bottom feet for adjusting the column length are provided at the bottom of each stable support column is adopted, the kiln car transfer vehicle is more stable when docking with the kiln car track inside the kiln body and has stronger load-bearing capacity. Since the technical feature that a vertically insertable and removable positioning lock pin is provided at the bottom of the kiln car transfer vehicle body on the side docking with the kiln car track and a positioning lock hole cooperating with the positioning lock pin is provided on the ground outside the kiln body is adopted, the position of the kiln car transfer vehicle can be effectively prevented from shifting during the process of the kiln car entering and leaving. Since the technical feature that a docking plug protruding from the end face of the outer track is provided at the rail head of the docking end of the outer track and a docking slot for movably inserting and mating with the docking plug is opened at the rail head of the docking end of the kiln car track is adopted, the docking of the outer track and the inner track is more convenient, and it is not easy to be misaligned after docking, and the kiln car enters and leaves the kiln body more smoothly.
