- As disclosed in Japanese Patent Publication No. 17887, a removable platform is installed on the revolving body to raise the driver's cabin, or as disclosed in Japanese Patent Publication No. 11109/1987, a pair of Fix the cylinder body,
There is one that raises the driver's cab by extending the pair of piston rods. In the former case, it must be attached and detached every time the operator's cab is moved up and down.
The setup work requires a lot of time, and storage, etc., must be taken into account when the stand is not in use. The latter uses a cylinder to raise and lower the driver's cab, so it has the advantage of being easy to operate, but since the cylinder body side is used as a guide surface when raising and lowering the driver's cab, the cylinder body is constantly subject to lateral loads. At the same time, two cylinders and a guide bracket are required as reaction force fulcrums, resulting in a complicated structure. Further, since the raised set position of the operator's cab is maintained by switching control valves, there is a drawback that it cannot be maintained for a long time due to oil leakage, etc.

The object of the present invention is to provide a device for lifting and lowering the cab of a construction machine that can be held.

A pair of left and right columns 6 whose dimensions are set within the height of
The lower end of the support 6 is fixed, and the upper end is fixed to the frame 4 via the stay 5, while integrally connecting the support columns 6, 6 via a connecting member. An elevating cylinder 8 for raising the driver's cab 3 is disposed between the columns 6 and 6, and its piston rod 8b end is attached to the frame 4, and the cylinder body 8a side is attached to the driver's cab 3 via a support bracket 7. It is integrally attached to the bottom. Therefore, when the cylinder 8 is extended, the cylinder body 8a, the support bracket 7, and the driver's cab 3 move up as one. The support column 6 is formed of a member having at least U-shaped planes on the front and rear surfaces and the inner surface on the driver's cab 3 side, and has a prismatic cross section as shown in FIG. 8, for example. A pair of upper and lower rollers 9 and 10 are attached to the support bracket as guide means that move along the front and rear surfaces and the inner surface, respectively.

A bracket 12 having a locking groove 12a is fixed, and the locking groove 12a is provided at the lower part of the driver's cab 3.
A locking piece 11 that engages and disengages, and a spring 15 that presses the locking piece 11 into the locking groove 12a are provided. The locking piece 11 is attached to the lower end of the operating lever 13 that is swingably supported on the floor 3a of the driver's cab 3.
The other end side is connected via a link 14, and the movable end of the spring 15 is attached.

ことが考えられる。 Next, the inclination correcting means when the driver's cab 3 is raised and lowered will be explained. A pair of upper and lower rollers 9 attached to the support bracket 7 act as guide means to absorb the reaction force that causes the driver's cab 3 to tilt downward or upward.
When the force is received by the rollers 9a, 9b, 9c, and 9d, as shown in FIG.
9d holds the reaction force that causes the driver's cab 3 to spring upward. Therefore, due to long-term use, the distance between the roller surfaces of rollers 9a, 9b and 9c, 9d decreases l 2
If the width of the support column 6 is larger than l1 , the driver's cab 3 will tilt downward, and may also bounce upward due to impact during work or driving, resulting in an unstable condition.

設定したことを特徴とするものである。 FIGS. 6 to 8 show an embodiment for solving this problem. As shown in FIG. 8, if the distance between the roller surfaces is l 2 and the width of the support 6 is l 1 , then a rail-shaped spacer with a thickness t is connected to the support 6 and the roller so that l 2 = l 1 + t. 9, and the spacer is set to be divided into at least two parts, an upper and a lower part.

重によりシリンダ８が縮小する。 FIG. 10 shows an example of an operating hydraulic circuit for the lifting cylinder. When no lifting operation is performed, the oil discharged from the hydraulic pump 101 is transferred to the circuit 1.
05, flows to operation valve 103 and circuit 106.
When the operator's cab 3 is raised, when the lever 104 is operated in the A direction, the operating valve 103 is switched to the A position, and the pressure oil flows from the circuit 105 to the circuit 107, causing the cylinder 8 to extend. When the operator's cab 3 is lowered, operating the lever 104 in the direction B opens the operating valve 10.
3 is switched to the ``ro'' position, the pressure oil returns from the safety valve 102, the circuit 107 is connected to the circuit 106, and the pressure oil in the cylinder 8 is released. Therefore, the cylinder 8 contracts due to the weight of the driver's cab 3.

制限高さ以内に収められる。 Since the present invention is configured as described above, when the lifting cylinder 8 is extended, the driver's cab 3 is raised while being supported by the pair of supports 6, 6 by the rolling of the rollers 9, 10 as guide means. . At this time, since the rollers 9 guide the pillars 6, 6 from the front and back directions, it is possible to maintain the vertical inclination of the driver's cab 3, vibrations, etc. Further, the roller 10 is connected to the support 6,
6 is guided from the side, the inclination of the driver's cab 3 in the left-right direction can be maintained. Therefore,
The driver's cab 3 can be raised stably by one cylinder and simple guide means. Driver's cab 3
8, the locking piece 11 slides along the inclined surface 12b of the bracket 12 while being pressed by the spring 15, and is pushed into the locking groove 12a. . Therefore, the raising of the driver's cab 3 is stopped and it is mechanically held at this set raised position. As a result, when working with a crane or the like for a long time in this state, even if the cylinder holding force decreases due to leakage of operating pressure oil, etc. inside the cylinder, the operator's cab 3 and support column 6 6, the driver's cab 3 is reliably held in the raised setting position. Furthermore, this locking means has the advantage that by arbitrarily setting the brackets 12 or by providing an arbitrary number of brackets 12, the raised setting position of the driver's cab 3 can be changed or added. When lowering the operator's cab 3 after completing the work, as shown by the two-dot chain line in Fig. 9,
When the operating lever 13 is swung against the pressing force of the spring 15, the driver's cab 3 is disengaged from the columns 6, 6, so that the driver's cab 3 is lowered by its own weight.
In this case, although not shown, the driver's cab 3 can be lowered slowly by means such as a circuit throttle. In the lowered position of the driver's cab 3 shown by the two-dot chain line in FIG. 3, so the total height of the vehicle or the upper revolving structure etc. in the case of disassembled transportation can be kept within the vehicle height limit.

きる。 Next, the installation order of the driver's cab inclination correcting means in the present invention will be explained. First, as shown in FIG. 7, when the support bracket 7 is in the lower position (the lowered position of the driver's cab 3), install (or replace) the spacer 21a, and then as shown in FIG. move to the raised setting position of the operator's cab 3) and install (or replace) the spacer 21b. In this way, the spacers 21a and 21b can be easily installed (replaced) by simply lifting and lowering the operator's cab 3, without having to hang the operator's cab 3 with another crane, etc., and l 2 = l 1 +t. Since it can be held, the operator's cab can be moved up and down stably over a long period of time.
