[0041] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0042] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical content disclosed by the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of implementation. The change or adjustment of their relative relationship should also be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0043] The present application discloses a cab for industrial and mining vehicles, which has sufficient falling object protection and rollover protection capabilities. The cab is divided into a driving position and an operating position, and can be used for different types of mining machinery, such as a rock drilling trolley, an anchor trolley, a mining trolley, etc.

[0044] The cab includes a top plate assembly 1 , a first column 2 , a cab door 3 , a damping part 4 and a bottom plate 5 .

[0045] The top plate assembly 1 is the main functional component of the falling object protection, including the top plate 11, the mounting plate 12 located directly below the top plate 11, and the support beam 13. A cavity is formed between the top plate 11 and the mounting plate 12, and the mounting plate 12 is provided with a plurality of air-conditioning outlets and filter element quick-change ports 125. The support beam 13 connects the top plate 11 and the mounting plate 12.

[0046] An air conditioning system is provided in the cab, which includes an evaporator 14. The evaporator 14 is accommodated in a cavity formed by a top plate 11 and a mounting plate 12, and the evaporator 14 is connected to some air conditioning outlets on the mounting plate 12 through pipes. The air conditioning outlets face the driving position, the operating position and the area therebetween, ensuring that heat exchange can be performed in all areas of the cab.

[0047] Specifically, the air outlet of the air conditioner includes a first air outlet 121, a second air outlet 122, a third air outlet 123 and a fourth air outlet 124, wherein the first air outlet 121 faces the operating position; the second air outlet 122 faces the driving position; the third air outlet 123 and the fourth air outlet 124 face the area between the two.

[0048] There are no less than two first columns 2, which are symmetrically distributed on both sides of the top plate assembly 1. The first columns 2 have a yield strength of no less than 355 MPa and are the main functional components for providing rollover protection and are also used to support the cab. The two ends of the first columns 2 are respectively connected to the top plate assembly 1 and the bottom plate 5. More specifically, the top of the first columns 2 is connected to the support beam 13.

[0049] In order to achieve stable opening and closing of the cockpit door 3, the present application provides a damping part 4 for controlling the stable opening and closing of the cockpit door 3, one end of the damping part 4 is movably connected to the first column 2, and the other end is movably connected to the cockpit door 3.

[0050] The damping part 4 includes a hydraulic damping gas spring 41, a sliding guide rail 42 and a rubber stopper 43, wherein the hinge point between the hydraulic damping gas spring 41 and the first column 2 is a first hinge point 411, and the hinge point between the hydraulic damping gas spring 41 and the cockpit door 3 is a second hinge point 412; the sliding guide rail 42 is sleeved on the hydraulic damping gas spring 41, and the hinge point between the end of the sliding guide rail 42 and the first column 2 is a third hinge point 421, and a through hole 422 is provided at the end of the sliding guide rail 42 away from the first column 2, and the through hole 422 is in a long strip shape, and the second hinge point 412 can slide along the through hole 422, and the rubber stopper 43 is located at the head end of the sliding guide rail 42, and is used to limit the hydraulic damping gas spring 41.

[0051] In order to prevent the cockpit door 3 from swinging back and forth after opening to a certain position due to the continued movement of the telescopic inertia after the gas spring in the hydraulic damping gas spring 41 rebounds, the travel of the through hole 422 provided in the sliding guide rail 42 is smaller than the movable travel of the gas spring. In other words, when the cockpit door 3 is opened to the extreme position and the hydraulic damping gas spring 41 moves along the through hole 422 to the head end of the sliding guide rail 42, the gas spring is always in a compressed state, so it will not continue to move due to the telescopic inertia, thereby avoiding the structural vibration of the cockpit door 3 and preventing the hydraulic damping gas spring 41 from being overstretched and damaged during use. In addition, when the cockpit door 3 is opened to the extreme position, the hydraulic damping gas spring 41 touches the rubber stopper 43, further ensuring that the hydraulic damping gas spring 41 is limited.

[0052] More specifically, when the cockpit door 3 is unlocked, the door opens automatically under the action of the hydraulic damping gas spring 41. After the gas spring moves a certain distance, it enters the hydraulic damping stage, that is, the opening speed of the cockpit door 3 decreases from fast to slow until it stops completely.

[0053] The bottom plate 5 and the top plate 11 are preferably a whole steel plate with a yield strength of not less than 355 MPa, which can provide overall strength for the entire cab. A plurality of rubber plates are arranged on the bottom plate 5, wherein the bottom rubber plate 51 is used for vibration reduction and sound absorption, and the surface rubber plate 52 is used for sound insulation and anti-skid. The bottom rubber plate 51 is softer than the surface rubber plate 52. The bottom of the bottom plate 5 is supported by the bearing plate assembly 10.

[0054] The cab also includes a front window 6 and a rear window 7. The front window 6 is tilted and faces the operating position, so that the operator can observe the geology ahead. The front window 6 uses multi-layer PVB laminated glass (PVB: polyvinyl butyral resin), which can not only reduce noise but also resist the impact of falling rocks that may occur during rock drilling operations.

[0055] The front window 6 is installed in the first mounting beam 15, the upper end of the first mounting beam 15 is connected to the top plate assembly 1, and the lower end is connected to the upper end of the front wall assembly 16. The top plate assembly 1 and the front wall assembly 16 are connected through the second column 17. The first mounting beam 15, the front wall assembly 16 and the second column 17 form a bending rigidity support for the front part of the cab.

[0056] The rear window 7 is installed in the second mounting beam 18, the upper end of the second mounting beam 18 is connected to the top plate assembly 1, the lower end is connected to the rear panel assembly 19, and the second mounting beam 18 and the rear panel assembly 19 are connected to the first pillar 2 on the side. The first pillar 2, the second mounting beam 18 and the rear panel assembly 19 form a bending rigidity support for the rear of the cab.

[0057] The rear window 7, the second mounting beam 18, the rear panel assembly 19 and the end of the top panel assembly 1 near the first pillar 2 are all uniformly arc-shaped. The rear of the cab is hinged to the frame. In order to prevent the cab from colliding with the hinged frame during driving and turning, the above components are preferably set to be arc-shaped. In addition, the arc-shaped rear window 7 provides the driver with a wider field of vision.

[0058] The cab also includes a seat 9, a seat shaft 92 is provided at the bottom of the seat 9, the seat shaft 92 is fixedly connected to the seat 9, and the seat 9 drives the seat shaft 92 to rotate, and the cab also includes a swing arm 95, one end of which is used to support the seat shaft 92 and is rotatably connected to the seat shaft 92. The seat shaft 92 is connected to a transmission mechanism, and when the seat 9 drives the seat shaft 92 to rotate, the transmission mechanism drives the swing arm 95 and the seat 9 to swing with the other end of the swing arm 95 as the swing point.

[0059] Specifically, the transmission mechanism adopts belt transmission, including a first gear 93 fixedly connected to the seat shaft 92 , a second gear 94 fixedly connected to the cab, and a transmission belt 96 tensioned between the first gear 93 and the second gear 94 .

[0060] The transmission mechanism further includes a mounting shaft 97, the second gear 94 is fixedly connected to the mounting shaft 97, and the other end of the swing arm is rotatably connected to the mounting shaft 97. The swing arm 95 is preferably rotatably connected to the seat shaft 92 and the second gear 94 through a bearing.

[0061] The swing arm 95 drives the seat 9 to rotate, so as to realize the switching of the seat 9 between the driving position and the operating position.

[0062] The specific rotation method is as follows: when the operator needs to switch work positions, the operator provides a rotational driving force to the seat shaft 92 by rotating the body. Since the seat shaft 92 is fixedly connected to the first gear 93, the rotational driving force is synchronously provided to the first gear 93, and the transmission belt 96 is meshed with the first gear 93 and the second gear 94. Since the second gear 94 is fixedly connected to the cab through the mounting shaft 97 and cannot rotate, the first gear 93, during its own rotation, drives the transmission belt 96 together with the swing arm 95 to rotate through the gear meshing action and the belt transmission principle, thereby realizing the switching of the seat 9 between the two work positions.

[0063] More specifically, the rotation direction of the seat shaft 92 and the first gear 93 is opposite to the rotation direction of the swing arm 95, that is, if the seat shaft 92 and the first gear 93 rotate counterclockwise, the swing arm 95 rotates clockwise, and vice versa. Since the gear ratio of the first gear 93 to the second gear 94 is 1:2, when the first gear 93 rotates 180 degrees counterclockwise, the swing arm 95 rotates 90 degrees clockwise. In this way, when the seat 9 is in the operating position, it can face the operating table 8, and when it is switched to the driving position, it is a side sitting position relative to the rear window 7.

[0064] A positioning pin 91 is also provided at the bottom of the seat 9, and a pin hole used in conjunction with the positioning pin 91 is provided on the swing arm 95. When the positioning pin 91 is inserted into the pin hole, the seat 9 and the swing arm 95 are limited.

[0065] Since the vertical height between the seat 9 and the cab floor 5 is relatively large, a footrest is provided under the operating platform 8. During rock drilling operations, the operator can lift his feet onto the footrest to improve comfort.

[0066] During rock drilling operations, the noise is relatively high. In order to reduce noise pollution, various sealing and noise reduction measures are taken in the cab: a sound-absorbing sponge sticker is affixed to the bottom of the top plate assembly 1, sound-absorbing sponges are provided on the inner sides of the front panel assembly 16 and the rear panel assembly 19, sound-absorbing sponges are provided on the first pillar 2 and the second pillar 17, the front window 6 uses PVB laminated glass with no less than 3 layers of glass, a rubber plate is provided on the driving position for anti-slip and sound insulation, a sealing strip is used on the cockpit door 3, and sound-absorbing sponges are provided inside.

[0067] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
