Description

  The present invention relates to a driving chair used in a paving machine such as an asphalt finisher, and more particularly to a driving chair that does not get in the way even when an operation is performed on a screed step at the rear of the driving chair.

  FIG. 1 is a side view showing a state of an operator 4 sitting on a driving chair 1 and driving a paving machine 2. In the case of running on public roads and performing general pavement, the operator 4 usually controls the pavement machine 2 by sitting on the driving chair 1 and manipulating the maneuvering device 3 as shown in FIG. However, in an emergency or the like, the operator 4 is forced to operate the control device 3 on the step 7. Since the conventional driver chair 1 has a plug-in structure, in such an emergency, the operator 4 pulls the driver chair 1 out of the frame cover 5 of the screed 6 and removes the driver chair 1 on the road or the like. In the work. FIG. 2 is a side view showing a state of the operator 4 who works by pulling out the driver chair 1. It is also described in Patent Document 1 that a conventional driver chair can be inserted and removed.

  By the way, since the paving site of the asphalt road is a place that has only been temporarily partitioned, the removed driver chair 1 is often disturbed and handled poorly, even in an emergency, etc. It is often left unattended and lost or damaged. Therefore, a technique for preventing the driver chair 1 from getting in the way when the operator 4 works in step 7 while preventing the driver chair 1 from being lost or damaged is disclosed in Patent Document 2.

  As shown in FIG. 4A of the literature, the first pillar (31) and the second pillar (32) are perpendicular to each other in the driver chair of Patent Document 2. It is attached to the bracket base (24). The first pillar (31) and the second pillar (32) are rotatably fixed on the lower surface of the bracket base (24). The second pillar (32) is shorter than the first pillar (31). As shown in FIG. 4A, when the operator works while sitting on the driver's chair, the first pillar (31) is inserted into the support hole (37). On the other hand, when the operator works on the step, the second pillar (32) is inserted into the support hole (37) as shown in FIG. 4 (b). 4 (b), the driver's chair can be lowered, and as shown in FIG. 6, even when the operator is on the step, paving work can be performed while checking the control device. .

  However, even if the structure as in Patent Document 2 is adopted, there is no substitute for having a driver's chair in front of the operator, and it is still difficult to maneuver and is not a fundamental solution. In particular, in the case of an emergency, a reliable operation is required. Therefore, if there is a driving chair in front of the operator, the upper part of the chair hits the elbow, and there is a risk of an operation error. Therefore, even if it is a structure like patent document 2, after all, a driver chair will be removed and used.

  Therefore, it is desirable to prevent the driver chair and its mounting part from obstructing the operation when standing on the screed step and preventing the driver chair from hitting the operator's elbow etc. and making an operation error. As much as possible, the operator should move the driver's chair smoothly without imposing a burden on the operator, and prevent damage or loss due to removal.

  Therefore, the present invention does not interfere with pavement machines even when maneuvering on the steps behind the driver's chair, even when not used as a driver's chair, without being forced to operate quickly and without inconvenience. It is an object of the present invention to provide a driving chair that can effectively utilize the mounting portion of the chair if desired.

  In order to solve the above problems, the present invention has the following features. The present invention is a pavement machine including a driver chair provided behind a steering device and on an upper part of a screed, the driver chair being centered on a rotation center on the right side or the left side of the driver chair. It can be moved to the right side or the left side and can be fixed. Preferably, the driver chair includes a first support column on which the driver chair is erected, and includes a rotation stopper that can fix the first support column after the driver chair rotates.

  Preferably, the center of rotation on the right side or the left side of the driver chair is a second support column that stands in connection with the driver chair, and the rotation stopper can insert the first support column, The driver chair can be moved to the right side or the left side and can be fixed by rotating the driver chair in the center and inserting the first support column into the rotation stopper.

  Preferably, the rotation center on the right side or the left side of the driver chair is a lower end of the third column that is obliquely connected to the driver chair, and the rotation stopper can be inserted into the first column. The driver chair can be moved to the right or left side and can be fixed by rotating the driver chair around the lower end of the lens and inserting the first support column into the rotation stopper.

  For example, at least one of a light oil spray hose for cleaning, a tool box, a hook, or a basket is installed in a member for moving the driver chair.

  Preferably, the driver chair is fixed so as to be lower after moving to the right or left side than when the driver chair is disposed behind the control device.

  Further, the present invention is a paving machine including a driving chair provided behind the control device and above the screed, and the driving chair can be moved to the right side or the left side of the control device and fixed. It is characterized by being able to. For example, the driver chair may be fixed by sliding to the right side or the left side by the slide part and the fixing part.

  According to the present invention, the center of rotation on the right or left side of the driver chair can be moved to the right or left side of the control device and can be fixed. Even when the maneuvering must be performed on the rear step, the maneuvering device can be operated promptly and without being forced to perform an inconvenient operation. In addition, since the driver chair can move to the right or left, it does not get in the way even when not used as a driver chair. The simple structure of the first support column and the rotation stopper can prevent the driver chair from being damaged or lost. If the second support is used as a rotation method, the operator can easily move to the right side or the left side as if turning the driver chair. If the third support column is used as the rotation method, the operator can easily move to the right side or the left side as if the driver chair was folded. If at least one of a light oil spraying hose for cleaning, a tool box, a hook, or a basket is installed on a member for moving the driver chair, for example, a plate portion attached to the driver chair, It can be used effectively. By making the driver's chair after movement lower than the driver's chair before movement, it becomes easy to perform work on the screed such as attachment and removal of the gas cylinder. In addition, the driver chair can be moved to the right or left side and fixed by any means, but the operation of the control device is facilitated while preventing the driver chair from being damaged or lost. For example, if a slide part and a fixing part are used, it can be moved and fixed without rotating the driver chair.

  These and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

  Hereinafter, although embodiment of this invention is described, since the structure of the whole paving machine in this embodiment is the same as that of FIG. 1, suppose that FIG. 1 is used.

(First embodiment)
FIG. 3A is a plan view showing a screed portion of the paving machine 2 according to the first embodiment of the present invention. FIG. 3B is a rear view showing the screed portion. FIG. 3C is a rear view showing a state when the driver chair 11 is pulled out. FIG. 3D is a plan view when the driver chair 11 is rotated. FIG. 3E is a rear view when the driver chair 11 is rotated. In FIG. 3E, the first support column 12 inserted into the third insertion portion 17 is indicated by a solid line so that the position of the first support column 12 can be understood. It is inserted into the part 17. FIG. 3E shows a state where the screed 6 is shortened by shortening. In addition, in FIG. 3B, FIG. 3C, and FIG. 3E, the 2nd insertion part 16 is a partially broken figure.

  As shown in FIGS. 1 and 3A to 3E, the paving machine 2 includes frame covers 5 and 8 that cover the screed 6, and includes a driver chair 11 on the frame cover 5 and behind the control device 3. . A first column 12 is attached below the driver chair 11. The first support column 12 is inserted into a first insertion part 15 provided in the frame cover 5 to make the driver chair 11 stand. Further, an arm portion 14 and a second support column 13 connected in an L shape are attached under the driver chair 11. The 2nd support | pillar 13 is inserted in the 2nd insertion part 16 so that rotation is possible. In the state shown in FIG. 3B, the first support column 12 is inserted into the first insertion portion 15, so the driver chair 11 is fixed without rotating. As shown in FIG. 3C, when the driving chair 11 is lifted and the first support column 12 is pulled out from the first insertion portion 15, the driving chair 11 can be rotated about the second support column 13. it can. After the rotation, when the first support column 12 is inserted into the third insertion portion 17 provided in the left frame cover 8 and the driver chair 11 is fixed, as shown in FIG. It will move to the left side. The third insertion portion 17 functions as a rotation stopper for fixing the first support column 12.

  The depth of the third insertion portion 17 may be the same as the depth of the first insertion portion 15, but may be deeper than the depth of the first insertion portion 15. FIG. 3E shows a case where the depth of the third insertion portion 17 is made deeper than the depth of the first insertion portion 15. As shown in FIG. 3E, the second insertion portion 16 allows the second support column 13 to be inserted all the way into the interior, and if the third insertion portion 17 is deepened, the driver chair 11 is provided. Can be fixed so as to be lower than when it is arranged behind the control device 3. If the driver chair 11 is lowered, it becomes easier to perform work on the screed by attaching and removing the gas cylinder.

  Thus, according to 1st Embodiment, the 1st support | pillar 12 which makes a driving chair stand, the 2nd support | pillar 13 used as a rotation center, and the 1st support | pillar 12 after rotation are inserted, and it serves as a rotation stop part. By using the functioning third plug 17, the driver chair 11 can be moved to the left. As a result, the rear of the control device 3 is completely opened, so that the driver chair 11 does not get in the way even when the operator 4 rides on the step 7 to work. Therefore, there is no inconvenience in the operational feeling of the control device 3. Since the driver chair 11 remains attached to the paving machine 2, it can be prevented from being lost or damaged. The movement of the driver chair 11 is very simple because it is only necessary to lift the driver chair 11 a little, rotate it around the second support column 13, and insert the first support column 12 into the third insertion portion 17. It is. Therefore, there is almost no burden on the operator 4 due to the movement of the driver chair 11.

  In the embodiment shown in FIGS. 3A to 3E, the driving chair 11 is moved to the left as viewed from the back surface with the second support column 13 as the center of rotation. However, the embodiment is not limited to the left side. If the configuration of the screed 6 and the frame cover 5 is changed to provide a symmetrical configuration so that the driver chair 11 can be moved to the right side, the driver's seat can be moved to the right side of the control device and fixed.

  In 2nd Embodiment, the 2nd insertion part 16a is long upwards compared with 1st Embodiment, and the 2nd support | pillar 13 is inserted in the 2nd insertion part 16a. It is like that. In the second embodiment, a plate portion 21 is attached to the arm portion 14, and two hooks 22 are attached to the plate portion 21. A light oil spray hose 23 for cleaning is wound around the hook 22. Similar to the first embodiment, the operator 4 can rotate the driver chair 11a during the operation in Step 7. However, in 2nd Embodiment, since the 2nd insertion part 16a is long upwards, after rotating the driver's chair 11a, let's insert the 1st support | pillar 12 in the 3rd insertion part 17. Even so, the driving chair 11a stops halfway. Thereby, even after the rotation, it is possible to obtain a space for securing a place for the cleaning light oil spraying hose 23.

  In this way, by providing the hook 22 at the attachment portion of the driver chair 11a, the portion of the driver chair 11a can be effectively utilized by, for example, winding the washing light oil spraying hose 23. Even after the driver's chair 11a is rotated, the washing light oil spraying hose 23 can be wound and stored.
