Description

  The present invention relates to an engine-driven generator, and more specifically, an arrangement of an output terminal board to which externally connected devices are connected in an engine-driven generator in which components such as a generator body and an engine are housed in a package. The present invention relates to an engine-driven generator having a structure.

  Portable packaged engine-driven generators that contain the generator body and the engine, fuel tank, and other necessary equipment for driving the generator body in a package are used in construction sites, event venues, and disaster-stricken areas. Widely used to obtain power in etc.

  Such an engine-driven generator package generally includes a base frame on which the above-described engine and generator main body and other necessary equipment are placed, and the engine and generator main body covering the base frame. The box is composed of a bonnet that houses the engine, and the engine, generator body, fuel tank, and other necessary equipment are housed in the package formed in this way. In addition to protecting the equipment from wind and rain, it prevents the noise generated when the engine or generator body is driven from leaking outside.

  The engine-driven generator configured as described above is provided with an operation panel provided with a control panel for controlling the engine, the generator main body and the supplied power, various switches and instruments, An output terminal board is provided for supplying electric power generated by the generator main body to externally connected devices arranged outside the package.

  Such an operation panel and output terminal board are located on the bonnet side wall so that the switches on the operation panel can be operated from outside the package and external wiring can be connected to the output terminals provided on the output terminal board. In general, an opening for an operation panel and an opening for an output terminal board are provided, and an operation panel and an output terminal board are attached to the inner wall of the bonnet at the position where these openings are formed.

  However, when adopting the above-mentioned configuration of operation panel and output terminal board, if the side wall with the operation panel and output terminal board attached to the inner surface is removed, the operation panel and output terminal board will be removed together with the side wall. Every time it is attached or detached, the internal wiring connected to the operation panel or the output terminal board needs to be attached and detached, which is complicated.

  Therefore, in order to eliminate the above complexity, the applicant of the present application places the generator main body 230 in the package so that the end cover 231 faces one side wall (rear cover 212) of the bonnet as shown in FIG. In the engine-driven generator 200 arranged, a plurality of legs 221 erected from a base frame in a package, and a horizontal member 222 laid between the upper ends of the legs 221 lie across the generator body 230. A gate-type gantry 220 is provided, and the control panel 260 is placed on the gantry 220, and the operation panel 250 and the output terminal board 270 are placed toward the openings 241 and 242 provided on one side wall (rear cover 212). The adoption of the structure attached to 220 is proposed (refer patent document 1).

  In this configuration, even if the rear cover 212 is attached or detached, the operation panel 250 and the output terminal board 270 can be left in the machine while being attached to the gantry 220. This can be performed separately from the work of detaching the in-machine wiring from the output terminal board 270.

Japanese Patent No. 4854361

  In a multi-mix assembly line that assembles multiple models, there is no variation in work time on each model assembly line. A “subassembly” is performed in which the groups are modularized, and the modularized component devices are assembled in advance before being introduced into the main assembly line for assembling the main components such as the engine and the generator main body.

  In the configuration of the engine-driven generator 200 described in Patent Document 1 described above, the gantry 220, the control panel 260, the operation panel 250, and the output terminal board 270 are combined into one module, and the assembly and wiring thereof are sub- By carrying out as an assembly, in the assembly line, the engine and generator main body are assembled on the base frame and the above-described sub-assembly base module is placed, and the wiring from the control panel 260 is connected to the engine and generator main body 230. This makes it possible to simplify the work on the assembly line, such as completing the wiring work.

  However, in the configuration described in Patent Document 1 described above, the output terminal board 270 is attached to the horizontal member 222 of the gantry 220 so as to face the rear cover 212 side (see FIG. 7). The workability at the time of attaching the in-machine wiring to the panel 270 is not good, and not only the trouble such as incorrect wiring or attachment failure is likely to occur, but also the inspection and inspection work after the wiring work is difficult to be performed. The workability during maintenance is also reduced.

  In other words, in the engine-driven generator 200 described in Patent Document 1, the in-machine wiring is attached to the output terminal board 270 by the subassembly so that the rear side of the gantry 220 (the rear cover 212 when the assembly of the engine-driven generator 200 is completed). When the output terminal board 270 is viewed from the rear side of the pedestal 220, the in-machine wiring connection terminal 272 provided on the back surface of the output terminal board 270 becomes a blind spot. The connection work of the wiring with respect to the wire is carried out by frustration, so the workability is poor, and miswiring, mounting failure, etc. are likely to occur.

  In order to solve such a problem, for example, the attachment work of the output terminal board 270 to the gantry 220 is performed from the rear side of the gantry 220, and the connection work of the in-machine wiring to the output terminal board 270 is performed from the front side of the gantry 220 (engine The worker may move around the pedestal 220 or rotate the pedestal 220 according to the work content, such as from the front cover 211 side when the assembly of the drive generator 200 is completed. Although it is conceivable, the output terminal board 270 is attached to the horizontal member 222 on the rear side (rear cover 212 side) of the pedestal 220, so that if the work is performed from the front side (front cover 211 side) of the pedestal 220, the output terminal board 270 is output. Since the terminal board 270 is located at the back of the pedestal 220, the poor workability is still not solved, and Move around the pedestal 220 for each, or the work for rotating the gantry 220 is troublesome. In addition, miswiring and mounting defects are inspected in the final inspection (for example, pre-trial inspection) after the assembly of the generator is completed via the assembly line, and after shipment, the user loosens, disconnects, breaks, etc. However, since the inspection and inspection of the output terminal board 270 are performed with the rear cover 212 removed and the rear part of the bonnet open, the engine-driven power generation described in Patent Document 1 is performed. In the machine 200, it is necessary to check the wiring attachment state with respect to the in-machine wiring connection terminal 272 provided on the back surface of the output terminal board 270 by looking into the back surface of the output terminal board 270 from below the gantry 220. The worker is forced to take an unreasonable posture.

  Moreover, even if the back surface of the output terminal board 270 is looked at in this way, it is difficult to see the connection portion of the wiring to the in-machine wiring connection terminal 272, and it is easy to overlook defects such as miswiring, loosening, disconnection, and disconnection. .

  In order to solve such a problem, for example, it is conceivable to inspect the back surface of the output terminal board 270 using a mirror. However, the wiring is inspected and inspected based on the mirror image that is reversed left and right, and loosened or detached. Skill is required to perform the work to correct.

  Further, a user who uses the engine-driven generator 200 not only checks the internal wiring of the output terminal board 270 but also replaces the generator main body 230 and removes dust and the like attached to the coil. It is necessary to perform periodic maintenance operations such as air blow, but these operations are performed with the end cover 231 of the generator body 230 removed.

  However, in the configuration of the engine-driven generator 200 described in Patent Document 1 in which the output terminal board 270 is attached to the horizontal member 222 of the gantry 220 as described above, the output terminal board 270 includes: Since it is arranged so as to cover the front of the upper end portion of the end cover 231 of the generator body 230 (see FIG. 7), for example, when removing the bolt that fixes the end cover 231, the tool is connected to the output terminal board 270. For example, sufficient work space for removing the end cover 231 is not ensured, and the maintainability of the generator main body 230 is not good.

  Therefore, the present invention has been made to solve the above-described drawbacks of the prior art, and by improving the workability in the sub-assembly by facilitating the in-machine wiring work for the output terminal board, and at the time of inspection and maintenance By making it easy to check the back of the output terminal board, it is easy to find problems such as incorrect wiring during inspection and inspection, loosening or disconnection of wiring, and disconnection, and the end cover of the generator body It is an object of the present invention to provide an engine-driven generator having an output terminal board arrangement structure that can improve the maintainability of the generator body by securing a sufficient working space in front.
