The movable portion 32 is configured to be vertically slidable with respect to the fixed portion 31 . As the movable portion 32 slides, the elevating portion 30 can expand and contract in the axial direction (vertical direction).

The driving section 40 shown in FIGS. 1 and 2 is for driving (extending and retracting) the lifting section 30 . The driving section 40 has an air compressor 50 and an adjusting section 60 .

The air compressor 50 is for supplying compressed air to the lifting section 30 . The air compressor 50 according to the present embodiment is not mounted on the truck portion 10 and is provided so as not to move integrally with the truck portion 10 .

The adjustment section 60 is for adjusting the amount of expansion and contraction of the lifting section 30 . The adjusting section 60 is arranged between the central shaft 21 and the air compressor 50 . The adjuster 60 includes an adjuster body 61 , a lever 62 , a pressure gauge 63 , a first hose 64 and a second hose 65 .

Thereby, the lever 62 is swung from the initial position shown in FIG. 2 to operate the valve to open the guide passage. As a result, the lever 62 communicates the air compressor 50 and the fixed portion 31 of the lifting portion 30 via the first hose 64, the adjustment portion main body 61 (the guide passage), the second hose 65, and the central shaft 21. can be done. When the operator releases the lever 62, the lever 62 can be returned to its initial position to operate the valve to close the guide passage and release the communication state between the air compressor 50 and the fixed portion 31. can.

The grip portion 70 shown in FIGS. 1 and 3 is intended to be gripped by an operator. The grasping portion 70 includes a shaft member 71 , a first metal fitting 72 , a second metal fitting 73 and a pin 74 .

The shaft member 71 is arranged with its axial direction facing rearward and downward (front and upward), and is arranged behind the lifting section 30 . The shaft member 71 is configured to be extendable and contractible in the axial direction by a large-diameter portion 71a formed in a cylindrical shape and a small-diameter portion 71b slidable on the inner peripheral surface of the large-diameter portion 71a. The small diameter portion 71b is arranged behind and below the large diameter portion 71a. The shaft member 71 can be contracted by sliding the small-diameter portion 71b forward and upward relative to the large-diameter portion 71a. Further, the shaft member 71 can be extended by sliding the small-diameter portion 71b rearward and downward relative to the large-diameter portion 71a. Such a shaft member 71 is configured to be able to maintain a state in which the amount of expansion/contraction (length) is adjusted.

The first metal fitting 72 , the second metal fitting 73 and the pin 74 are for attaching the shaft member 71 to the lifting section 30 . The first metal fitting 72 is fixed to the upper end portion of the large diameter portion 71 a of the shaft member 71 . The second metal fitting 73 is fixed to the upper portion of the movable portion 32 of the lifting portion 30 .

The shaft member 71 of the grasping portion 70 configured in this manner is configured to be vertically swingable with respect to the movable portion 32 around the pin 74 . Further, the shaft member 71 integrally moves up and down according to the sliding of the movable portion 32 (extension and contraction of the lifting portion 30).

The driving part 80 is a part for driving the screw A into the board C1. The driving unit 80 is configured by an electric screw driving device. The driving section 80 includes a driving section main body 81 , a slide section 82 and a storage section 83 .

The driving part main body 81 is formed in a gun shape. The driving section main body 81 is arranged to the left of the movable section 32 and arranged so that the rear portion and the movable section 32 overlap in a side view. The driving portion main body 81 is fixed to the upper portion of the movable portion 32 (above the portion to which the second metal fitting 73 is fixed). Inside the driving unit main body 81, there are provided a motor that is driven when power is supplied, a bit that is rotated by driving the motor, and the like.

The slide portion 82 is the tip (front end) of the driving portion 80 . The slide portion 82 is configured to be slidable back and forth with respect to the driving portion main body 81 .

The storage portion 83 is a hollow portion for storing the screws A. As shown in FIG. The storage portion 83 is connected to the slide portion 82 via a predetermined supply mechanism (not shown). The storage portion 83 is configured so that the screw A can be supplied into the slide portion 82 by the supply mechanism.

The driving part 80 configured in this way can drive the screw A into the board C1 by pressing the slide part 82 against the board C1. Specifically, when the slide portion 82 is pressed against the board C<b>1 , it slides rearward and enters (contracts) into the driving portion main body 81 . At this time, the screw A is supplied from the reservoir 83 into the slide portion 82, and the screw A is rotated by the bit. The screw A is pushed forward from the slide portion 82 and moves forward on the board C1 while being rotated. Thus, the driving section 80 can drive the screw A into the board C1.

Next, the operation of the driving device 1 will be described with reference to FIGS. 4 to 7. FIG.

In the following, the operation of the driving device 1 will be described by taking as an example the operation of driving a screw A at the point P shown in the upper end of FIG. 4 (the state after the screw A has been driven under the point P) is assumed to be the initial state, and the operation of driving the screw A into the point P will be described below.

First, in the driving operation to the point P, the worker raises the driving part 80 . At this time, the operator grips the shaft member 71 of the grip portion 70 with one hand. Also, the operator grips the adjusting portion main body 61 and the lever 62 of the adjusting portion 60 with the other hand. As a result, as shown in FIG. 5, the operator connects the air compressor 50 and the fixed portion 31 of the lifting portion 30, and supplies the compressed air from the air compressor 50 to the fixed portion 31 (indicated by the arrow in FIG. 5). air flow shown).

When compressed air is supplied to the fixed portion 31, the pressure inside the fixed portion 31 increases, and the lower surface of the movable portion 32 is pressed upward. Thereby, as shown in FIG. 6, the movable portion 32 slides upward with respect to the fixed portion 31 . Thus, the lifting section 30 lifts the driving section 80 fixed to the movable section 32 .

The operator raises the driving part 80 until the sliding part 82 of the driving part 80 reaches the same height position as the point P by operating (grasping) the lever 62 in this manner.

Next, the operator moves the driving part 80 forward as shown in FIG. At this time, the worker moves the driving part 80 forward by, for example, tilting the lifting part 30 forward about the lower end of the support part 20 (leg part 22). As a result, the driving part 80 is brought closer to the board C1 and the sliding part 82 is brought into contact with the board C1 (point P). When the driving part 80 is further moved forward from this state, the sliding part 82 of the driving part 80 is pressed against the board C1. This allows the operator to drive the screw A into the point P.

As described above, when the slide portion 82 is pressed against the board C1, the screw A is supplied from the storage portion 83 into the slide portion 82. As shown in FIG. As a result, the labor for setting the screw A to the slide portion 82 can be saved, so that the operator can repeatedly lift the driving portion 80 and press the slide portion 82 . As a result, the screw A can be continuously driven from bottom to top, and the screw driving work can be efficiently performed.

According to the driving device 1 of the present embodiment, the driving part 80 can be lifted by the elevating part 30, so that screws can be placed on the board C1 at a high place (for example, a place out of reach) without climbing a stepladder or the like. You can type A. According to this, the worker does not have to go up and down the stepladder or the like in the work of driving the screw into the board C1. Therefore, it is possible to reduce the burden of the operation of driving the screw A, and to efficiently perform the operation of driving the screw A.

When lowering the driving part 80, the operator releases the lever 62 and returns the lever 62 to the initial position. As a result, the operator releases the communication state between the air compressor 50 and the fixed portion 31 to stop the supply of compressed air to the fixed portion 31 . Compressed air in the fixed portion 31 slightly leaks from gaps (fine gaps for sliding) between the inner periphery of the fixed portion 31 and the outer periphery of the movable portion 32 . Therefore, when the supply of compressed air is stopped, the pressure in the fixed portion 31 gradually decreases, and the movable portion 32 gradually slides downward as the pressure decreases. In this way, the worker can lower the driving part 80 . In this way, the adjustment unit 60 can adjust the amount of elevation of the driving unit 80 (the amount of expansion and contraction of the elevation unit 30) by switching between supplying and stopping the supply of compressed air from the air compressor 50 to the fixing unit 31. .

Further, the drive unit 40 according to the present embodiment raises and lowers the elevation unit 30 by the air compressor 50 . The air compressor 50 is generally used at a construction site for purposes other than lifting of the lifting section 30 (for example, a driving source for an air tool for driving a screw A using compressed air, etc.). For this reason, an air compressor 50 is generally brought to the construction site. In the driving device 1 according to the present embodiment, the driving source of the lifting unit 30 is a device that is generally brought to such a construction site. According to this, since it is not necessary to bring a separate drive source to the construction site, the practicality of the driving device 1 can be improved.

Further, by using the air compressor 50, the drive section 40 can increase the reaction speed compared to the case where the movable section 32 is lifted by hydraulic pressure. As a result, the movable portion 32 can be quickly raised by operating the lever 62, and the work of driving the screw A can be efficiently performed. Further, unlike the present embodiment, if the elevation unit 30 is raised and lowered by hydraulic pressure, there is a possibility that the floor B or the like will become dirty due to leakage of fluid (operating oil). , the lifting unit 30 is moved up and down. According to this, it is possible to prevent the floor B and the like from being soiled due to fluid leakage.

Also, the operator can support the vicinity of the driving part 80 by gripping the grip part 70 (shaft member 71). As a result, the driving device 1 can be balanced, so that the driving part 80 can be stably moved. As a result, the screw A can be stably driven.

In addition, since the grasping portion 70 is configured to be swingable on the movable portion 32 , the shaft member 71 can be oriented optimally according to the movement of the driving portion 80 . Specifically, the grip portion 70 rises as the driving portion 80 rises (see FIG. 6). In this case, by swinging the shaft member 71 downward, the shaft member 71 faces vertically (substantially in the vertical direction), and the position of the lower end of the shaft member 71 can be lowered. This makes it easier for the operator to grip the shaft member 71 . Further, when the driving portion 80 is to be moved forward, the shaft member 71 can be swung upward so that the shaft member 71 faces sideways (substantially in the front-rear direction), making it easier to press the slide portion 82 against the board C1. Become. By optimizing the direction of the shaft member 71 in accordance with the movement of the driving portion 80 in this way, it is possible to improve the workability of screw driving.

Further, the shaft member 71 according to the present embodiment is configured such that its length becomes longer than the length of the fixed portion 31 by stretching (see FIG. 3). According to this configuration, the height position of the lower end of the shaft member 71 can be lowered to some extent. Therefore, even if the driving part 80 is raised, the lower end of the shaft member 71 can be easily positioned within reach of the operator. This makes it easier for the operator to grip the shaft member 71 .

Further, in the driving device 1 according to this embodiment, the driving part 80 can be easily moved in the horizontal direction by moving the carriage part 10 . Thereby, the screw A can be driven in efficiently.

As described above, the driving device 1 according to the present embodiment includes the driving section 80 for driving the screw A (fastener) into the board C1 (wall) of the building, the lifting section 30 for lifting and lowering the driving section 80, and the lifting section and a drive unit 40 for driving the 30 .

With this configuration, the work of driving the screw A into the board C1 can be efficiently performed. Specifically, by raising and lowering the driving portion 80, the screw A can be easily driven into a high portion of the board C1. As a result, the screw A can be driven into a high portion of the board C1 without going up and down a stepladder or the like.

Further, the elevating section 30 elevates and lowers the driving section 80 by extending and contracting with power from the driving section 40. The driving section 40 includes an adjusting section 60 for adjusting the amount of expansion and contraction of the elevating section 30. is provided.

With this configuration, the screw A can be driven while adjusting the amount of expansion and contraction of the elevating section 30 by the adjusting section 60 . Therefore, the operation of driving the screw A can be performed more efficiently.

Further, the lifting section 30 is configured to be movable with respect to the fixed section 31 (non-movable section) that is not driven by the power from the drive section 40 and the fixed section 31 that is driven by the power from the drive section 40. and a movable portion 32 to which the driving portion 80 is attached, and the driving device 1 further includes a grip portion 70 attached to the upper portion of the fixed portion 31 or the movable portion 32. is.
In the present embodiment, the upper portion of the fixing portion 31 means at least above the upper and lower central portions of the fixing portion 31 .

By configuring in this way, it is possible to improve the accuracy of screw driving. Specifically, by gripping the grip portion 70, the screw A can be driven while the driving device 1 is balanced. Thereby, the screw A can be stably driven.
In particular, by attaching the gripping portion 70 to the movable portion 32, the height positional relationship between the driving portion 80 and the gripping portion 70 can be maintained regardless of the height at which the screw A is driven. As a result, the screw A can be easily driven while the grip portion 70 is gripped.

Further, the holding portion 70 is configured to be vertically swingable with respect to the lifting portion 30 .

With this configuration, the gripping portion 70 can be oriented optimally when the elevating portion 30 is moved up and down and when the screw A is driven (when the driving portion 80 is moved), thereby improving screw driving workability. can be made

Further, the drive unit 40 includes an air compressor 50 that drives the lift unit 30 by air pressure (by switching between supply and stop of supply of compressed air).

By configuring in this way, it is possible to drive the lifting section 30 using the air compressor 50 that is easily procured, so that practicality can be improved.

The driving section 80 is configured to rotate the screw A to drive the screw A into the board C1.

With this configuration, the rotation of the screw A can move the screw A forward with respect to the board C1. According to this, since the reaction force received from the board C1 when driving the screw A can be reduced, the screw A can be driven stably.

Further, the driving portion 80 starts rotating the screw A by pressing the slide portion 82 (tip portion) holding the screw A against the board C1.

With this configuration, if the lifting section 30 is moved and the sliding section 82 of the driving section 80 is pressed against the board C1, the driving section 80 can be directly operated (for example, the driving section main body 81 can Screw A can be driven in without pressing a switch or the like. Therefore, workability of screw driving can be improved.

In addition, the fixed part 31 according to the present embodiment is an embodiment of the non-movable part according to the present invention.
Further, the slide portion 82 according to this embodiment is an embodiment of the tip portion of the driving portion according to the present invention.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above configurations, and various modifications are possible within the scope of the invention described in the claims.

For example, although the driving device 1 according to the present embodiment drives the screw A into the board C1 of the inner wall C, the member into which the screw A is driven is not limited to the board C1. may be

Further, although the elevating section 30 elevates and lowers the driving section 80 by expanding and contracting, the configuration of the elevating section 30 is not limited to this, and other configurations may be employed. Specifically, the elevating unit 30 may have a configuration including, for example, a rail supported by the floor B and the ceiling, and a moving body that elevates the driving unit 80 by elevating the rail. . In addition, the structure can be simplified by configuring the elevating unit 30 so as to be able to expand and contract as in the present embodiment. Therefore, the cost of the driving device 1 can be reduced, and the practicality can be improved.

In addition, although the driving unit 40 is configured to move the lifting unit 30 up and down by air pressure (using the air compressor 50), the means for lifting and lowering the lifting unit 30 is not limited to air pressure. , hydraulic pressure, or the like.

In addition, although the adjustment unit 60 adjusts the amount of expansion and contraction of the elevation unit 30 by using the lever 62, the adjustment unit 60 is not limited to this. You may

Moreover, although the gripping part 70 is attached to the movable part 32, the location to which the gripping part 70 is attached is not limited to this as long as the driving device 1 can be balanced. For example, like a grip part 170 according to a modified example shown in FIG. 8, it may be attached to the fixing part 31 of the lifting part 30 (above the vertical central part, upper end in FIG. 8). In this case, the grip portion 170 may have a configuration in which the second metal fitting 173 connected to the first metal fitting 72 is fixed to the fixing portion 31 . Moreover, the grasping portion 70 may be attached to a member other than the lifting portion 30 (for example, the driving portion 80 or the like).

Moreover, the grasping part 70 does not necessarily have to be configured to be swingable with respect to the lifting part 30 , and may be fixed to the lifting part 30 .

Also, in the present embodiment, the fastener is the screw A, but the type of the fastener is not limited to this, and bolts, nails, and the like may be used. Moreover, when the fastener is not formed with a male thread portion, such as when the fastener is a nail, the driving section 80 does not necessarily rotate the fastener, and the board C1 can be mounted without rotating the fastener. It may be something that is driven into.

Further, the driving device 1 only needs to be able to move the driving part 80 up and down, and does not necessarily have to include the carriage part 10, the support part 20 and the grip part 70.
