It may include a plurality of wheels or rollers 58 that are formed to move along the rail of the rail portion 51, the motor 59 is mounted on a part of the moving shaft 57 or the entire moving shaft 57, the moving body (55) can be moved. At this time, one end of the outrigger 30 is fixed to the moving body 55, so that the outrigger 30 can be formed to move inward and outward with respect to the base part 10.

The outrigger 30 moving to the inside and outside is a cylinder (not shown in FIG. 3), which further expands a reduction or expansion range that cannot be adjusted, diversifies the adjustment means of the outrigger, in particular, in addition to the flow rate adjustment of the outrigger By moving the outrigger according to the center of gravity, it can be balanced, so it can be effective in maintaining the horizontal.

Referring to FIG. 4, the air tube 60 may be mounted on the outrigger 30 or the traveling part 15 of the crane. That is, the air tube 60 may be individually installed for each outrigger, or individually for each wheel or track.

Here, the air tube 60 is formed to receive air from an air supply unit (not shown) that is installed inside or outside the crane only when in use, and through this, the air tube 60 is not used by blocking the air supply during normal use. When the inclined or unbalanced situation occurs due to eccentricity in the self-propelled crane, the air tube 60 is operated toward the inclined side, and the self-propelled crane receiving reaction force due to the expansion of the air tube 60 is hydraulic and In addition, there is an advantage of maintaining the balance by using pneumatics together.

On the other hand, the air tube 60 may also be capable of automatic or manual operation using the above-described horizontal sensor (not shown). To this end, the air supply unit (not shown) may be interlocked with a horizontal sensor (not shown).

5 to 7, the balance maintaining unit 70 includes a flow channel 71, a plurality of opening / closing valves 72, a plurality of individual pipelines 74, and a water supply unit 75, including a base unit 10 ).

Specifically, the flow pipe 71 forms a length along the circumference of the base portion 10, and an open / close valve 72 may be installed in various places along the length, and the flow pipe may be caused by the plurality of open / close valves 72. The furnace 71 may be divided into a plurality of zones 73. That is, as shown in the drawing, a first zone 73a is formed between the first on-off valve 72a and the second on-off valve 72b, and the second on-off valve 72b and the third on-off valve 72c are formed. The second zone 73b is formed therebetween.

The zoning flow conduit 71 may be provided with an individual conduit 74 for each zone 73, and a plurality of individual conduits 74 are connected to one or more feed pumps 76 from the water supply 75. Water (W) can be supplied.

For example, when the plurality of individual pipelines 74 are formed to supply water through one supply pump 76 as shown in FIG. 6 (a), the water supply pipeline 77 receiving water is The branch line 78 may be formed to be connected to a plurality of individual pipelines 74, where the plurality of individual pipelines 74 or the branch lines 78 are provided with valves 79, respectively, to go to an area in need of water supply. Can be formed. In addition, as shown in (b) of FIG. 6, when a plurality of supply pumps 76 are provided to supply water to a plurality of individual pipelines 74, a plurality of zones are divided into predetermined sections, each of which is a plurality. It can also be made to correspond to the supply pump (76). In addition, as shown in Figure 6 (c), it is also possible to provide a separate supply pump 76 for each individual pipeline (74).

The self-propelled self-propelled crane of the present invention through the above structure can maintain the balance by adjusting the water supply for each zone when balance is required. For example, as shown in (a) of FIG. 7, when the crane is inclined toward the first zone 73a, the sixth and seventh open / close valves 72e forming the fifth zone 73e facing the first zone 73a , 72f) is closed, the water (W) is supplied to the fifth zone 73e to balance it, and the vicinity between the second zone 73b and the third zone 73c is inclined as shown in FIG. 7 (b). In the vaginal period, after closing and closing the valves 72f to 72h forming the corresponding 6th zone 73f and 7th zone 73g, water W is supplied to maintain the balance. Through this, basically, in addition to maintaining the balance by using the flow rate, it is assisted through the balance maintaining unit 70, and there is an effect of preventing the rollover more safely and finely.

On the other hand, the flow pipe 71 can also be used where water is circulated or sprayed. To this end, the flow pipe 71 may separately include a water circulation pump (not shown) connected to the water supply unit 75, and is connected to one or more water jetting devices (not shown) in one or a plurality of zones. An injection pipe (not shown) may be formed.

First, circulating water is for cooling the surroundings of the base portion 10 of the crane, and has an effect of preventing the temperature rise of the crane, such as cooling water of a vehicle, and water spraying cools the surrounding heat and sprays water around the crane. Can be used when needed. Here, when it is desired to circulate water, all of the plurality of on-off valves 72 forming the zone may be opened and circulated.

In addition, a separate heat exchanger (not shown) may be used in the flow pipe 71 to use hot water instead of cold water. Hot water supplies warmth so that crane components work well in winter, etc., and snow on the ground (E) Stacking or freezing can have the effect of melting snow or ice when the movement is costly.

That is, the balance maintaining unit 70 primarily serves as an auxiliary for preventing the tipping of the crane, and secondly, a water circulation pump (not shown), a water spraying device (not shown), and a spray pipe (not shown), Including various heat exchangers (not shown), it can exhibit an effect of easily using the crane in various seasons.

The above-described moving part 50, the air tube 60, and the balance maintaining part 70 may all be provided separately or may be provided together. However, the moving part 50, the air tube 60, and the balance maintaining part 70 are used to assist the horizontal maintenance through the flow control, and primarily the horizontal maintenance through the flow control, 2 It is preferable to use the moving part 50 or the air tube 60 or the balance maintaining part 70 to lane horizontally. However, it is not necessarily limited, and it is possible to maintain the horizontal by utilizing only the moving part 50, the air tube 60, and the balance maintaining part 70.

Hereinafter, the ultra-small self-propelled spider crane 100, which is an example to which the self-propelled self-propelled crane according to the present invention can be applied, will be described in detail.

First, referring to FIGS. 8 to 10, the ultra-compact self-propelled spider crane 100 according to an embodiment of the present invention has a standard lift for 1 person, as described above, 1,350mm * 1,600mm * 2,050mm (depth * width * height, Door width: 900mm) smaller than 1,220mm * 600mm * 1,310mm (full length * full width * height) can be formed. (Here, the specifications of the miniature self-propelled spider crane are not limited to examples and can be adjusted within a range not exceeding the standard lift specification for 13 persons)

In addition, it may be configured to include a base portion 10, the lifting portion 20 and the outrigger 30, which is the basic configuration described above. However, some structures and configurations including the installation location of the outrigger 30 may exhibit differences. Therefore, hereinafter, redundant descriptions will be omitted, and only parts showing differences in the basic configuration will be described. (In the following, reference numbers will be written in units of 100, such as 110 for the base part, 120 for the lifting part, and 130 for the outrigger).

In the miniature self-propelled spider crane 100 according to an embodiment of the present invention, the outrigger 130 may be installed at a vertex position of the base 110. At this time, the outrigger 130 may be installed to be rotated left and right through a rotation bracket 132 to the rotation support portion 131 forming the vertical axis 131a at the vertex position of the base portion 110. Through this, it is installed at the vertex position of the base portion 110, but it is also possible to support the ultra-small self-propelled spider crane 100 by rotating the outrigger 130 in both sides or front and rear.

On the rotating bracket 132, a connecting link 133 is connected by a horizontal axis 133a, and an upper cylinder 135 connected to a connecting bracket 134 provided at an end of the connecting link 133 is mounted on the upper side. Can be. The linking link 133 can be rotated up and down by elongation and expansion and contraction to the upper cylinder 135. To the connection bracket 134, a multi-stage support 136 having a support portion 137 for seating on the ground may be connected by a horizontal axis 136a. In addition, the lower cylinder 138 supported by the connecting link 133 on the lower side of the connecting link 133 is mounted on the horizontal axis 136a coupling the support 136, so that the lower cylinder 138 is elongated and stretched. According to the support 136 may be formed to rotate based on the axis. In addition, the support portion 137 for being seated on the ground is formed to be rotatable with respect to the support 136, so that the outrigger 130 can be formed with a joint that can be adjusted at multiple angles and easily balances the ground. When running or not in use, the outrigger 130 may be folded and used as shown in FIG. 10.

On the other hand, the cylinder connecting the one end and the other end of the outrigger 130, which is a feature of the present invention (not shown in FIGS. 1 to 7), may mean the upper cylinder 135 or the lower cylinder 138 described above. have. That is, as a result, in the ultra-small self-propelled spider crane 100, it is possible to implement a self-propelled self-propelled crane by controlling the flow rate of the upper cylinder 135 or the lower cylinder 138 of the outrigger 130.

On the other hand, another feature of the miniature self-propelled spider crane 100 according to an embodiment of the present invention is that it can be used by extending the driving unit 115.

Specifically, referring to FIG. 11, as described above, the driving unit 115 may be formed in a wheel or a track type, and preferably may be formed in a track type so that it can be easily used even on an inclined or irregular surface. At this time, the track-type travel unit 115 may be extended to both sides by mounting the expansion cylinder 140, and the expansion range may be up to about 800 mm. That is, even if the track is extended, a structure smaller than the door width of the standard lift specification for 13 persons is formed, so that the elevator can be easily boarded at the time of expansion or non-expansion of the driving unit 115. When it is necessary to form a low center, the driving unit 115 can be extended and used. When there is no need to lower the center of gravity or relatively fast driving is required, the driving unit 115 can be used without being extended.

In addition, one feature of the ultra-compact self-propelled spider crane 100 according to an embodiment of the present invention is to drive a mixture of electricity and fluid with reference to FIG. 12. To this end, the miniature self-propelled spider crane 100 may be provided with a motor (not shown) that can be electrically driven and an engine (not shown) that can be driven with fluid, respectively, as described above. Power can be supplied from a supplied or separately mounted battery (not shown), and can be mainly used in indoor work requiring little power, and the engine can be mainly used in outdoor work requiring a lot of power.

However, the present invention is not necessarily limited, and it is possible to use the engine in indoor work or use the motor in outdoor work depending on the required force. Accordingly, the present invention may have an advantage of saving driving energy.

In addition, referring to FIG. 13, the ultra-compact self-propelled spider crane 100 according to an embodiment of the present invention allows the outdoor and indoor to be determined by itself, so that the driving of the motor and the engine can be automatically converted according to the determination.

To this end, the miniature self-propelled spider crane 100 may include one or more detection sensors (not shown) capable of detecting discrimination conditions such as distance or temperature so as to distinguish between indoor and outdoor differences. Here, the sensing sensor may be an ultrasonic or infrared sensor capable of determining distance, or the like, and may be a temperature sensor capable of determining temperature.

In the case of distance measurement, for example, in the case of distance measurement, since the upper side is mainly open, when the ultrasound or infrared rays are emitted upward, the response may not be made or the response may be slow, and the indoor side is mainly closed because the upper side is mainly closed. B When infrared rays are emitted upward, it can be used to distinguish between outdoor and indoor by confirming that the response is made within a certain time. In the case of temperature measurement, it can be distinguished by using the temperature difference between outdoor and indoor.

However, in the case of a temperature difference, it is preferable to accurately classify the distance and temperature together, since outdoor and indoor may be similar or the same, and in the case of temperature, the average temperature of the day is entered directly or the temperature is connected to the weather station to inform the temperature. A reference temperature may be automatically input for each time zone through a program or the like.

Accordingly, the ultra-compact self-propelled spider crane 100 of the present invention for driving the mixing of the motor and the engine, the operator can directly set the use of the motor and the engine, but may be set automatically and conveniently.

In addition, the ultra-compact self-propelled spider crane 100 according to an embodiment of the present invention, the base to be hooked to the base portion 110 when not using the ring 126 provided at the end of the winch 123 of the lifting portion 120 The hook 110 in front of the unit 110 may be further included. Accordingly, safe storage may be possible when the crane is not in use.

Such, the ultra-compact self-propelled spider crane 100 according to an embodiment of the present invention, includes the above-described base portion 110, lifting portion 120 and outrigger 130, while adjusting the balance with the flow rate while moving auxiliaryly The unit 50, the air tube 60 and the balance maintaining unit 70 may be further used to maintain the horizontal shape, and the engine and the motor may be used in combination, and the driving unit 115 may be extended. In particular, it has the advantage of being used in various ways, both outdoors and indoors.
