Obviously, the following described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0033] The technical solutions of the present application will be further described in combination with the drawings and through specific embodiments.

[0034] In the description of the present application, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0035] The application discloses a cab, which adopts a "C" type frame 1, i.e., a metal frame structure is adopted at the top, bottom and rear of the cab to form a "C" type, the frame adopts an extremely simple design, and the whole frame comprises the cab C type frame 1, a door bottom frame 6, a right front vertical column 8 and a left front vertical column 11. The right side of the cab comprises a right rear glass 2, a door upper glass 3, a door lower glass 4, the left side comprises a left glass 12, the front side comprises a front glass 10, and the rear side comprises a rear window glass 13, all of which are designed by using large-area glass to provide a wide and transparent visual range for the driver, as shown in Figure 1 、 Figure 2 、 Figure 3 The door upper glass 3 and the door lower glass 4 form a whole glass door, the glass door is opened and closed through a door hinge 5, a door handle 7 is further arranged on the glass door, a handrail 9 is arranged on the right front vertical column 8, and the driver is facilitated to enter and exit the cab.

[0036] After the cab is rotated by a certain angle, the driver can observe the whole drilling process of the tiger clamp, the power head and the drill rod connection, the drill rod loading and unloading area and the power head through the front glass and the left glass, the operation efficiency and safety are greatly improved. The driver sees the power head and the drill rod connection, the drill rod loading and unloading area and the power head drilling process (α1) through the left glass 12, sees the operation situation of the tiger clamp position (α2) through the front glass 10, and the left front vertical column 11 of the cab causes a visual blind area (α3), but the range is small and is not in a key area. The target position which the driver focuses on during the horizontal directional drilling operation of the cab is shown in Figure 4 、 Figure 5 .

[0037] The rotatable whole frame controls the rotation of the whole frame through a rotating platform arranged below the whole frame (the rotating platform adopts hydraulic control, a control end is arranged in the cab, and the rotation of the rotating platform is controlled through the operation of a button so as to control the rotation of the whole frame).

[0038] After the cab is rotated as a whole to meet the visual requirement during the horizontal directional drilling operation, the seat in the cab can not adopt a slanting or rotatable design, as shown in Figure 6 The seat 14 is arranged in the middle, a right handrest box 15 and a left handrest box 16 are arranged on the two sides of the seat respectively, a control handle 17 is installed on the right handrest box 15 and the left handrest box 16, and a display 18 is installed in the left front empty space to provide a wide visual field for the direction of the tiger clamp. The floor 19 in front of the seat has a large space, and enough space is left for the sliding of the seat and the legs of the driver.

[0039] Due to the limited length of the cab, the driver's legs are not in the visual field of the driver, as shown in Figure 7As shown, the right armrest box 15 can be flipped up, creating a wide access path for the driver to enter and exit from the right side. The base of the armrest box is connected to the base of the seat 14, so that the armrest box slides forward and backward with the seat through the seat adjustment device; the seat adjustment device is also used to rotate the seat; the seat adjustment device in the embodiment can use the existing seat adjustment device of the cab, and the specific structure is not described here.

[0040] A rotating structure can also be provided below the seat 14 to realize the rotation of the seat 14, so that the cab can be rotated under certain working conditions to perform corresponding operations.

[0041] Correspondingly, the application also provides a horizontal directional drilling rig, the left side of which is an automatic drill rod box 21, the middle is a drill rod running track 22, the cab and the hood 20 are on the right side, the rotation point of the cab 23 is arranged at the left front of the cab, and after the cab is rotated by a certain angle to the right, the vice 24, the automatic drill rod box 21 and the last end position of the power head running (the connection position of the power head and the drill rod 25) can be observed at the same time through the left front oblique angle of the hood 20.

[0042] After the cab is rotated as a whole, the position of the seat SIP point is determined according to the position of the seat in the cab, and the position of the driver's eye point 26 and the range of the eye ellipse are calculated according to the forward and backward sliding stroke of the seat, the seat backrest angle and other parameters. With the last end position of the power head movement as an end point, two straight lines are respectively drawn, which are tangent to the last end and the front end of the eye ellipse curve respectively, and the left front oblique angle edge of the hood 20 is designed to ensure that the two lines are not blocked. It is ensured that the driver can observe the connection position of the power head and the drill rod without turning his head; the hood 20 is only cut and folded in the upper area of the driver's line of sight, and the rest is still retained, providing enough space for the internal power system layout.

[0043] The cab is in a transport state ( Figure 4 ), the layout is compact and meets the requirements of container transportation; in a working state ( Figure 5 ), a sufficient safety distance is reserved from the drill rod loading and unloading area and the vice position.
