Description

  The present invention relates to a mechanical parking device that is used outdoors and has two or more pallets, and more particularly to a snow melting device for a mechanical parking device that can melt snow that has fallen on an upper pallet. is there.

  Conventionally, in order to efficiently increase the number of cars parked in an outdoor parking lot, a two-stage or three-stage elevating parking apparatus has been proposed. As shown in both cross-sectional views of FIGS. 5 and 6, the three-stage lifting / lowering parking apparatus is configured such that a pallet column 2 that supports three pallets 1 so as to sandwich the pallet 1 can be raised and lowered between main columns 3. It is. The pallet column 2 of the pallet 1 is moved up and down by a drive unit 4 provided on the main column 3. By operating the operation panel 5 and moving the pallet 1 together with the pallet support 2, the mounted vehicle 6 can be easily discharged from the pit 7.

  On the other hand, when the automobile 6 is stored in the lower pallet 1, the lower pallet 1 is raised to the storage level L together with the pallet column 2 and the automobile 6 is placed at this position. Similarly, when the automobile 6 is stored in the middle pallet 1, each pallet 1 is raised from the inside of the pit 7 together with the pallet column 2 to the entry / exit level L, and the automobile 6 is placed at this position.

  However, when the conventional mechanical parking apparatus is used in a snowfall region, snow may be deposited on the upper pallet 1. When the snow on the upper pallet 1 is high, there is a problem that it becomes difficult to mount the automobile 6. Further, if the snow on the pallet 1 is not removed, a part of the snow melts and flows out due to the temperature rise in the daytime, and this moisture flows into the main strut 3 part and the drive part 4, and this mechanism part due to the subsequent temperature drop. As a result, the pallet column 2 is difficult to lift and lower, and the vehicle 6 cannot be smoothly loaded into and unloaded from the mechanical parking device.

  Thus, in the heavy snow region, the mechanical parking device in which the pallets 1 are arranged in two or several stages is used indoors, or a building with a roof is surrounded so as to surround the mechanical parking device. It had a problem that it could not be used without construction.

  The present invention has been developed to solve such problems. That is, the object of the present invention is to melt the snowfall on the pallet so that the vehicle can be smoothly loaded and unloaded even in the case of a mechanical parking device used outdoors in a snowfall region. It is to provide a snow melting device for a mechanical parking device that can be automatically implemented.

  According to the snow melting device of the mechanical parking device of the present invention, the pallets (1) arranged in a plurality of stages are moved up and down between the main struts (3) provided in the pit (7), and each pallet (1) is moved to the automobile. In the mechanical parking apparatus capable of storing (6), a mechanical type characterized in that a heater (12) is attached to the upper pallet (1) and the snowfall accumulated on the pallet (1) is melted. A snow melting device for a parking device is provided.

  The snow melting device of the mechanical parking device may further include a temperature sensor provided on the upper pallet, and the heater may have the pallet (1) when the temperature sensor (14) senses a predetermined temperature rise. The heating is stopped.

  Further, in the snow melting device of the mechanical parking device described above, a snowfall sensor that detects snowfall, a first electrical contact provided at a position that moves up and down together with the upper pallet or the upper pallet of the mechanical parking device, and the upper pallet is an automobile And the second electric contact that is connected to the first electric contact when the upper pallet is at a position higher than the car loading / unloading level, and is separated from the first electric contact. Detects a snowfall and when the upper pallet is at the loading / unloading level of the automobile, electric power for heating is supplied to the heater via the first electric contact and the second electric contact, and the upper pallet is moved from the loading / unloading level. When the first electrical contact and the second electrical contact are separated from each other by raising to an upper position, the power supply for heating to the heater is cut off.

  According to the present invention, since the heater is attached to the pallet, the snowfall accumulated on the pallet can be melted with a simple configuration. Management of the heating temperature of the pallet can also be performed reliably. Therefore, even if a roof is not provided outdoors in the snowy region, it is possible to smoothly enter and exit the vehicle with respect to the mechanical parking device.

It is an expanded sectional view which shows a warm air injection apparatus part. It is side sectional drawing which shows embodiment of the snow melting apparatus of the mechanical parking apparatus of this invention. It is a bottom view which shows the pallet which stuck the heater. It is a front sectional view showing a conventional three-stage lift parking device. It is a sectional side view which shows the conventional three steps raising / lowering parking apparatus.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing a reference example of a snow melting device of a mechanical parking device. This mechanical parking apparatus is configured such that a pallet column 2 that supports two pallets 1 so as to sandwich the pallet 1 is vertically movable between main columns 3. The pallet column 2 of the pallet 1 is moved up and down by a drive unit 4 provided on the main column 3. By operating the operation panel 5, the pallet 1 can be easily unloaded from the pit 7 by simply raising the pallet 1 together with the pallet support 2.

  FIG. 2 is an enlarged cross-sectional view showing a hot air injection device portion. In the pit 7, a hot air injection device 8 that injects hot air toward the upper pallet 1 is provided. The hot air injection device 8 includes a hot air generator 9 such as a boiler outside the pit 7, a pipe 10 for sending the hot air generated by the hot air generator 9 into the pit 7, and a pipe 10 at the tip of the pipe 10. It consists of the provided hot air injection port 11. The hot air injection port 11 is attached to the wall surface of the pit 7 so that the injection direction can be varied.

  Since it comprised in this way, the snowfall accumulated on this pallet 1 can be fuse | melted by injecting a warm air toward the upper pallet 1 with the warm air injecting device 8, so that it is a roof in the snowfall region outdoors. Even if it is not provided, it is possible to smoothly carry in and out of the automobile with respect to the mechanical parking device.

  Furthermore, since the hot air injection port 11 is provided on the wall surface of the pit 7 so that the injection direction can be changed, the direction of each hot air injection port 11 is directed over the entire lower surface of the upper pallet 1. The pallet 1 can be efficiently heated. Therefore, the snowfall on the pallet 1 can be quickly melted.

  FIG. 3 is a side sectional view showing an embodiment of the present invention. FIG. 4 is a bottom view showing a pallet with a heater attached thereto. In the embodiment of the present invention, a heater 12 is attached to the lower surface of the upper pallet 1 instead of the hot air injection device 8 of the reference example described above. The wiring 12a of the heater 12 does not straddle the reinforcing material 1a constituting the pallet 1, but penetrates the recess formed in the top plate 1b in order to increase the heat transfer efficiency to the upper surface of the pallet 1. is there. Therefore, the snowfall accumulated on the pallet 1 can be quickly melted.

  Further, in the configuration in which the heater 12 is attached to the pallet 1, not only can the snowfall that has accumulated efficiently be melted, but also the heating temperature can be reliably managed. For example, snow falls in a heavy snow region in a short time, and if the heating temperature is low, the snow may not be completely melted. In such a case, the heating temperature can be managed to be increased.

  According to the snow melting device of the mechanical parking device configured as described above, when the snowfall sensor 13 senses the snowfall state, when the snowfall sensor 13 senses the snowfall state, as described above, the hot air jet device 8 directs the pallet 1 to the upper pallet 1. Thus, warm air can be ejected from each warm air ejection port 11. Thereafter, the snowfall accumulated on the pallet 1 is melted, and when the temperature sensor provided on the pallet 1 detects a predetermined temperature rise, the hot air injection from the hot air injection device 8 is stopped. Although it is necessary to attach the temperature sensor to the pallet 1 itself, the snowfall sensor 13 is not necessarily provided on the pallet 1 and can be provided on the control panel 5 as shown in FIG.

  In this way, the snowfall sensor 13 on the pallet 1 senses the snowfall state and can inject hot air toward the pallet 1 before the snow is piled up high, so that it is possible to melt the snow easily. When the snow melts and there is no new snowfall, the temperature on the pallet 1 rises. When this temperature rise is detected by the temperature sensor, waste of energy can be avoided by stopping the injection of hot air.

  Once the stopped snowfall comes down again, the snowfall sensor 13 detects the snowfall state and starts jetting warm air. Further, instead of the method of injecting hot air toward the pallet 1, the method of heating the pallet 1 with the heater 12 can also automatically melt snow.

  Furthermore, when the pallet 1 is raised and the vehicle 6 is moved in and out, if the hot air from the hot air injection device 8 is injected, a problem that snow or water droplets are applied to a person getting on and off the vehicle 6 occurs. There is. Therefore, for example, the upper pallet 1 is configured so that the hot air is injected or the heater 12 is heated only when the pallet 1 is lowered, and the hot air is injected or the heater 12 is stopped when the pallet 1 is raised. The first electrical contact 15a such as a connector provided on the pit 7 and the second electrical contact 15b joined thereto can be provided in the pit 7 (see FIGS. 1 and 3). In addition, the position where each electrical contact 15a and 15b is attached is not limited to the upper pallet 1, but may be the pallet column 2, and can be changed without departing from the gist of the present invention.

  The above-mentioned snow melting device of the mechanical parking device is a hot air jetting device provided in a pit, and melts the snowfall accumulated on this pallet by spraying the hot air toward the upper pallet or heating it with a heater. Therefore, even if a roof is not provided outdoors in the snowy region, it is possible to smoothly enter and exit the vehicle with respect to the mechanical parking device.

  Also, the hot air injection port can be heated efficiently by changing the injection direction on the wall surface of the pit so that the direction of each hot air injection port extends over the entire lower surface of the upper pallet. Snowfall on this pallet can be melted quickly.

  In addition, the above-mentioned snow melting device of the mechanical parking device can not only automatically carry out the snow melting work, but also the snow falling sensor on the upper pallet of the mechanical parking device senses the snow falling state and before the snow is piled up high. Since warm air can be sprayed on the pallet or the heater can be heated, it is possible to melt snow easily.

  Also, when the snow melts and there is no new snowfall, the temperature on the pallet rises, and when this temperature rise is detected by the temperature sensor, the warm air injection is stopped to avoid wasting energy. It has an excellent effect that snow can be melted easily and quickly.
