Description

Technical Field

[0001] This application relates to the field of concrete wet spraying machine technology, and more particularly to a cab for a trolley and a wet spraying machine with a trolley cab. Background Technology

[0002] Wet shotcrete machines are commonly used for spraying and protection after excavation in underground mines and engineering tunnels. They are typically modeled by their pumping capacity, which allows them to deliver concrete in cubic meters per hour. For example, the UPS-30 wet shotcrete machine indicates a conveying capacity of 30 cubic meters per hour. 3 The wet concrete spraying machine (hereinafter referred to as wet spraying machine) is commonly used in tunnel engineering.

[0003] For existing wet spraying machine cabs, such as the UPS-30 model mentioned above, the machine itself is relatively large. Following the guidelines of GB / T21938 "Comfort Zones and Accessibility of Earthmoving Machinery Operation," the various functional areas of the cab can be easily and rationally arranged within the cab. However, in underground metal mines, wet spraying machines of the UPS-20, UPS-18, and smaller models are typically used. These models facilitate movement through underground tunnels and allow for turning within the tunnels using the machine's designed minimum turning radius. Compared to the UPS-20, UPS-18, and smaller models, their overall design height is ≤1800mm, and their overall design width is within the range of 1600-1800mm. Therefore, for cab design, this means that the cab's external dimensions are compressed along with the overall machine dimensions, making the division of the cab and its various functional areas more difficult. Utility Model Content

[0004] In view of this, this application provides a cab for a trolley and a wet spraying machine with a trolley cab, which can realize the arrangement of a comfortable operating area in a compact driving space, improve the sense of driving boundaries through a reasonable structure, and ensure the comfort of the cab.

[0005] In summary, in order to optimize the compact layout of the cab space, enhance the sense of boundaries for driving, and improve the comfort of the cab, this application proposes a cab for a trolley and a wet spraying machine with a trolley cab.

[0006] The technical solution provided in this application for a cab for a bogie is as follows:

[0007] A cab for a trolley includes a body, a roof assembly, a door assembly, and a seat assembly. The roof assembly is connected to the body, the door assembly is also connected to the body, and the seat assembly is also connected to the body. The body includes a first floor plate, and the seat assembly includes a seat base and a seat. One end of the seat base is connected to the first floor plate, and the other end is connected to the seat. The body has an operating box on one side of the seat assembly that also serves as a seat armrest, and an armrest platform on the other side of the seat assembly.

[0008] By adopting the above technical solution, when the driver is sitting in the seat, the left side of the driver is the armrest, the right side is the control box, and the top is the canopy assembly. This makes the driver's seat layout compact, the division of each area clear, and can also enhance the sense of boundary of the cab. Furthermore, it allows the driver to rest his elbow on the armrest and the top surface of the control box for comfortable operation, further improving the driving and riding comfort.

[0009] Preferably, the seat has a seat surface, the distance between the seat surface and the side wall of the control box on the side near the control box is 40mm-100mm, and the distance between the seat surface and the side wall of the armrest on the side near the armrest is 40mm-50mm.

[0010] By adopting the above technical solution and setting different distance values ​​between each part of the control box and the seat surface, the cab space can be used efficiently while ensuring the driver's comfort.

[0011] Preferably, the control box includes a flat portion, which includes a front portion, a middle portion, and a rear portion. The distance between the side wall of the rear portion and the edge of the seat surface is B1, where B1 = 100mm ± 15mm. The distance between the side wall of the middle portion and the edge of the seat surface is B2, where B2 = 40mm ± 15mm. The distance between the side wall of the front portion and the edge of the seat surface is B3, where B3 = 75mm ± 15mm.

[0012] By adopting the above technical solution, the rear of the control box allows for a full release of the driver's hip space, preventing the hip bones and muscles from being tense due to the compact space in the cab. This facilitates the extension of the thighs to the outside of the seat. The middle of the control box facilitates the placement of the driver's elbows, and the front of the control box allows the driver's thighs and knees to extend to both sides when sitting in the seat, making it easier to control the throttle, etc.

[0013] Preferably, the seat base is a conical component, the lower end of the seat base has a second cavity, the seat base is rotatably connected to the first base plate, and the seat base is also detachably fixedly connected to the first base plate.

[0014] By adopting the above technical solution, the second cavity can be used to place hydraulic and electrical components. The utilization of the second cavity further optimizes the overall vehicle layout space. At the same time, the height formed by the upper and lower surfaces of the cone component can be adapted to different models of seats, and cone components of different heights can be obtained by changing the upper and lower surfaces, thereby adapting to drivers of different heights.

[0015] Preferably, the main body further includes a support component, one end of which is connected to the first base plate and the other end of which is connected to the canopy component. The support component has a recessed area, and the edge contours of the support component and the recessed area are covered with soft components.

[0016] By adopting the above technical solution, the driver's activity space is increased through the recessed area, and the soft components covering the recessed area effectively protect the driver's head, preventing the driver's head from hitting the recessed area due to vehicle bumps, and further improving driving comfort.

[0017] Preferably, the main body further includes a main component, which includes a skeleton, a boundary component, and a bending component. The skeleton is connected to the support assembly. One end of the boundary component is connected to the first base plate, and the other end is connected to the skeleton. The bending component is shaped like a "7". The lower end of the bending component is connected to the first base plate, and the upper end is connected to the boundary component, so that the upper surface of the bending component forms the armrest surface.

[0018] By adopting the above technical solution, the armrest platform can be used as the driver's operating platform, which not only frees up space for the driver's left elbow and improves the driver's driving comfort, but also has practical value.

[0019] Preferably, the control box further includes an inclined portion located at the front end of the flat portion, the inclined portion being arranged at an angle α with the flat portion, the angle being in the range of 100-115°.

[0020] By adopting the above technical solution, the instrument panel is bolted to one end of the inclined part near the flat part, and the instrument panel is arranged at an angle α with the flat part. The frequently used buttons are placed at the lower end of the instrument panel, while the less frequently used buttons and electrical components with display functions are placed at the upper end of the instrument panel. Thus, the distance between the instrument panel and the seat reference point (SIP) of the seat is arranged in a far-to-close manner through the angle α. This makes it easier for the driver to operate the frequently used buttons without raising their elbow, which, compared with the prior art, ensures the comfort of the control area, improves the control efficiency, and reduces fatigue. The upper end of the instrument panel is farther and higher than the seat reference point (SIP), which makes it easier for the driver to observe the electrical components with display functions, thereby reducing driver visual fatigue.

[0021] Preferably, one end of the control box is connected to the support assembly of the main body, and the other end is connected to a rod-shaped member. The rod-shaped member is connected to the first base plate of the main body. The control box has a bending adjustment member on its lower side near the support assembly. The bending adjustment member is inverted "L" shape and includes an upper end and a left end. The upper end has a horizontal elongated hole, and the left end has a vertical elongated hole. The bending adjustment member is connected to the control box through the horizontal elongated hole and to the support assembly through the vertical elongated hole.

[0022] By adopting the above technical solution, the driver can adjust the distance between the control box and the seat surface through the horizontal elongated hole, and adjust the height of the control box through the vertical elongated hole, thereby appropriately adjusting the installation position of the control box, so as to meet the needs of drivers of different heights.

[0023] Preferably, a first groove is formed on the rear side of the control box near the seat, such that the distance between the rear side wall of the control box and the seat is greater than the distance between the middle side wall of the control box and the seat; and a second groove is formed on the front side of the control box near the seat, such that the distance between the front side wall of the control box and the seat is greater than the distance between the middle side wall of the control box and the seat.

[0024] By adopting the above technical solution, the distance between the rear side wall of the control box and the edge of the seat surface is B1, B1 = 100mm ± 15mm; the distance between the middle side wall of the control box and the edge of the seat surface is B2, B2 = 40mm ± 15mm; and the distance between the front side wall of the control box and the edge of the seat surface is B3, B3 = 75mm ± 15mm. This allows the driver's buttocks to have room to move, and the driver can rest their elbows on the armrest and the upper surface of the control box for comfortable operation. It also makes it easier for the driver's thighs to extend outwards from the seat.

[0025] A wet spraying machine with a trolley cab includes a cab and a frame as described above, wherein the cab is connected to the frame.

[0026] By adopting the above technical solution, when the driver is operating the wet spraying machine, the driver's left side is the armrest platform, the right side is the control box, and the top is the canopy assembly. This makes the driver's driving position layout compact, the division of each area clear, and also enhances the sense of boundary of the cab. Furthermore, it allows the driver to rest his elbow on the armrest platform and the upper surface of the control box for comfortable operation, further improving driving comfort.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the driver is seated, the left side of the driver is the armrest, the right side is the control box, and the top is the roof assembly. This makes the driver's seat layout compact and the areas clearly divided. It also enhances the sense of boundaries in the cab and allows the driver to rest their elbows on the armrest and the top of the control box for comfortable operation, further improving driving comfort.

[0029] 2. By setting different distance values ​​between each part of the control box and the seat surface, the cab space is used efficiently while ensuring the driver's comfort. The rear of the control box allows for full release of the driver's hip space, preventing the hip bones and muscles from being tense due to the compact space in the cab, thus facilitating the extension of the thighs to the outside of the seat. The middle of the control box facilitates the placement of the driver's elbows, and the front of the control box allows the driver's thighs and knees to extend to the sides when sitting in the seat, making it easier to control the throttle, etc.

[0030] 3. The recessed area frees up the driver's movement space, and the soft components covering the recessed area effectively protect the driver's head, preventing the driver's head from hitting the recessed area due to vehicle bumps, and further improving driving comfort.

[0031] 4. The inclined section is bolted to the end of the flat section, which is arranged at an angle α with the flat section. The instrument panel is arranged with frequently used buttons at the bottom and less frequently used buttons and electrical components with display functions at the top. The angle α makes the distance between the instrument panel and the seat reference point (SIP) of the seat vary, so that the lower part of the instrument panel is closer to the seat reference point (SIP), which makes it easier for the driver to operate frequently used buttons without raising their elbow. Compared with the existing technology, this ensures the comfort of the control area, improves the operation efficiency, and reduces fatigue. The upper part of the instrument panel is farther and higher than the seat reference point (SIP), which makes it easier for the driver to see electrical components with display functions, thereby reducing driver visual fatigue.

[0032] 5. The driver can adjust the distance between the control box and the seat surface through the horizontal elongated hole, and adjust the height of the control box through the vertical elongated hole, thereby adjusting the installation position of the control box as appropriate to meet the needs of drivers of different heights.

[0047] The following is in conjunction with the appendix Figure 1-13 This application will be described in further detail.

[0048] Example 1

[0049] This application discloses a driver's cab for a trolley.

[0050] Reference Figures 1-6 It includes a main body 1, a canopy assembly 2, a door assembly 3, and a seat assembly 4. The seat assembly 4 is connected to the main body 1, the door assembly 3 is also connected to the main body 1, the canopy assembly 2 is also connected to the main body 1, and the canopy assembly 2 can cover the seat assembly 4.

[0051] The main body 1 includes a first base plate 7, a second base plate 25, a support assembly 37, and a main body component 38. The second base plate 25 is located below the front side of the first base plate 7, forming a step with the first base plate 7. An accelerator pedal is located at the upper right corner of the second base plate 25, and an anti-slip mat 26 is laid on the second base plate 25. The support assembly 37 includes a first support rod 39, a second support rod 40, and a connecting plate 41. The first support rod 39 and the second support rod 40 are symmetrically arranged on both sides of the rear side of the first base plate 7. The lower ends of the first support rod 39 and the second support rod 40 are bolted to the first base plate 7. A canopy assembly 2 is inserted into the first support rod 39 and the second support rod 40, and the connecting plate 41 is bolted between the first support rod 39 and the second support rod 40. The main body component 38 is located at the first base plate 7. On the left side of the base plate 7, the main component 38 includes a skeleton 13, a boundary component 14, and a bending component 15. One end of the skeleton 13 is bolted to the side wall of the second support rod 40, and the other end extends parallel to the left side of the first base plate 7. The boundary component 14 is arranged to follow the shape of the skeleton 13. The upper end of the boundary component 14 is welded to the skeleton 13, and the lower end is welded to the left side of the first base plate 7 and the second base plate 25. The bending component 15 is shaped like a "7". The left side of the upper end of the bending component 15 is bolted to the boundary component 14, and the lower side of the bending component 15 is bolted to the first base plate 7, so that the upper surface of the bending component 15 forms the handrail surface 9. A first cavity 10 is formed between the bending component 15 and the boundary component 14. The first cavity 10 is located inside the handrail surface 9.

[0052] Seat assembly 4 includes a seat base 5 and a seat 6. The lower end of the seat base 5 is bolted to a first base plate 7, and the upper end of the seat base 5 is bolted to the seat 6. The seat 6 has a seat surface 11 with a width of 400mm. The first base plate 7 has a control box on the right side of seat assembly 4. One end of the control box is bolted to a support assembly 37, and the lower side of the other end is connected to a rod-shaped member 22. The lower end of the rod-shaped member 22 is bolted to the first base plate 7. The control box includes a flat portion 12, with a valve hole 43 on the upper side. The flat portion 12 has a third cavity 42, and a rod valve body is located inside the third cavity 42, extending from the valve hole 43 so that the rod valve body can be positioned on the flat portion 12. The flat portion 12 of the control box is 200mm-26mm higher than the seat surface 11. The control box is 0mm thick, so that the flat part 12 of the control box can be used as an armrest of the seat 6. The flat part 12 of the control box includes a front part, a middle part and a rear part of the control box. The distance between the side wall of the rear part of the control box and the edge of the seat surface 11 is B1, B1 = 100mm ± 15mm. The distance between the side wall of the middle part of the control box and the edge of the seat surface 11 is B2, B2 = 40mm ± 15mm. The distance between the side wall of the front part of the control box and the edge of the seat surface 11 is B3, B3 = 75mm ± 15mm. The armrest platform 9 is located on the left side of the seat 6. The distance between the side wall of the armrest platform 9 and the edge of the seat surface 11 is 40mm-50mm. The armrest platform 9 is also 200mm-260mm higher than the seat surface 11. The upper surface of the armrest platform 9 is flush with the upper surface of the flat part 12 of the control box 8.

[0053] When the driver is seated in seat 6, the left side of the driver is the armrest platform 9, the right side is the control box 8, and the top is the roof assembly 2. This clearly defines the different areas of the driver's seating position, enhancing the sense of boundary within the cab. Furthermore, by limiting the distance between the side of the seat surface 11 of seat 6 closest to the control box 8 and its side wall, and the distance between the other side of the seat surface 11 of seat 6 and the side wall of the armrest platform 9 of the main body 1, the driver's hips have room to move. Simultaneously, the driver can rest their elbows on the armrest platform 9 and the upper surface of the control box 8 for comfortable operation, freeing up elbow movement space and facilitating hand operation of valve stems, further improving driving comfort. The seating space is not compressed despite the reduction in the overall size of the cab as the machine's dimensions decrease. Moreover, the various parts of the control box 8... The different distances between the control box and the seat surface 11 allow for efficient use of the cab space while ensuring driver comfort. For example, the rear of the control box provides ample space for the driver's hips, preventing tension in the hip bones and muscles due to the cramped cab space, thus facilitating the extension of the thighs to the outside of the seat 6. The middle of the control box provides convenient elbow placement for the driver, while the front of the control box allows the driver's thighs and knees to extend to the sides while seated, enabling free operation of the accelerator pedal located in the notch area of ​​the anti-slip mat 26. Simultaneously, the thighs and knees, by conforming to the front of the control box, define the boundary of the accelerator pedal operation area and limit its movement, thereby enhancing driving safety. In this way, while defining space for the accelerator pedal within the cab, it also facilitates the arrangement of other control areas within the cab.

[0054] Furthermore, in this embodiment, a first groove 19 is formed on the rear side of the control box near the seat 6, such that the distance between the rear side wall of the control box and the seat 6 is greater than the distance between the middle side wall of the control box and the seat 6. A second groove 20 is formed on the front side of the control box near the seat 6, such that the distance between the front side wall of the control box and the seat 6 is greater than the distance between the middle side wall of the control box and the seat 6. This achieves a distance of B1 between the rear end of the control box 8 and the seat 6, where B1 = 100mm ± 15mm, and a distance of B2 between the middle of the control box and the seat 6, where B2 = 40mm ± 15mm. The value is B3, B3 = 75mm ± 15mm. The rear of the control box allows the first groove 19 to fully release the driver's hip space when the driver is sitting in the seat 6, so that the hip bones and muscles are not in a tense state due to the compact space in the cab, which makes it easier for the thigh to extend to the outside of the seat 6. At the same time, the space formed by the seat 6, the inner curved plate and the upper surface of the control box 8 also releases the elbow space, making it easier for the hand to operate the valve stem. The second groove 20 allows the driver's thigh and knee joints to extend to the front and outside of the inner curved plate when sitting in the seat 6, so that the lower leg and foot can be operated freely.

[0055] Furthermore, in this embodiment, referring to Figure 1 and Figure 7 An inverted "L"-shaped bending adjustment member 23 is bolted to the lower left side of the control box 8. The bending adjustment member 23 includes a horizontal plate portion 27 and a vertical plate portion 28. The left end of the horizontal plate portion 27 is integrally formed with the upper end of the vertical plate portion 28. The horizontal plate portion 27 of the bending adjustment member 23 is bolted to the lower side of the control box 8. The vertical plate portion 28 of the bending adjustment member 23 is bolted to a threaded hole plate 44. The vertical plate portion 28 of the bending adjustment member 23 is bolted to the support assembly 37 through the threaded hole plate 44. A rod-shaped member 22 is bolted to the lower right side of the control box. The lower end of the rod-shaped member 22 is bolted to the first base plate 7 of the main body portion 1.

[0056] Furthermore, in this embodiment, a horizontal elongated hole is provided on the horizontal plate portion 27, and a vertical elongated hole is provided on the vertical plate portion 28. The values ​​of B1, B2, and B3 can be adjusted appropriately through the horizontal elongated hole of the bending adjustment member 23, and the installation height of the control box 8 can be adjusted appropriately through the vertical elongated hole of the bending adjustment member 23. This can meet the needs of drivers of different heights, so that the values ​​of B1, B2, and B3 can all be adjusted by ±15mm.

[0057] Furthermore, in this embodiment, referring to Figure 8 The control box 8 has an inspection hole 29 on the side near the seat 6. The inspection hole 29 facilitates the installation and maintenance of the rod valve body pipeline placed inside the control box 8. The control box 8 also has a blind plate component 30 at the inspection hole 29, so that the inspection hole 29 is connected to the blind plate component 30.

[0058] Furthermore, in this embodiment, the tilting portion 21 of the control box 8 also includes an inclined portion 21, which is integrally formed with the flat portion 12. The upper plane of the flat portion 12 is arranged at an angle α with the tilting portion 21, where the angle α is in the range of 100-115°. The width of the tilting portion 21 is smaller than the width of the flat portion 12 of the control box 8, and the upper width of the tilting portion 21 is smaller than the lower width of the control box 8. An instrument panel is bolted to one end of the tilting portion 21 near the flat portion 12, and the instrument panel is arranged at an angle α with the flat portion 12. Commonly used buttons are located at the lower end of the instrument panel. Less frequently used electrical components, as well as those with display functions, are positioned at the upper part of the instrument panel. This arrangement uses an α angle to represent the distance between the instrument panel and the seat reference point (SIP) of the seat 6, making the lower part of the instrument panel closer to the seat reference point (SIP) of the seat 6. This allows the driver to operate frequently used buttons without raising their elbow. Compared with existing technologies, this ensures the comfort of the control area, improves control efficiency, and reduces fatigue. Meanwhile, the upper part of the instrument panel is farther and higher than the seat reference point (SIP) of the seat 6, making it easier for the driver to observe electrical components with display functions, thereby reducing driver visual fatigue.

[0059] Furthermore, in this embodiment, referring to Figure 1 and Figure 6 The boundary component 14 includes an upper boundary 31 and a lower boundary 32. The upper boundary 31 includes a first horizontal plate 16, a first vertical plate 17, and a first inclined plate 18. The first horizontal plate 16 is arranged parallel to the connecting plate 41. The rear end of the first horizontal plate 16 is bolted to the side wall of the support component 37, and the other end is integrally formed with the first vertical plate 17. The first vertical plate 17 is arranged perpendicular to the first horizontal plate 16. The first inclined plate 18 is integrally formed with the end of the first vertical plate 17 away from the first horizontal plate 16, and there is an angle between the first inclined plate 18 and the first vertical plate 17, with the angle being greater than 90°. The upper end of the lower boundary 32 is integrally formed with the lower end of the upper boundary 31, and the lower end of the lower boundary 32 is welded to the first base plate 7. An electrical control box is provided on the first inclined plate 18, which not only provides more space for the driver's left hand, but also allows the driver to install the electrical control box through the first inclined plate 18, making it convenient for the driver to observe and operate.

[0060] Furthermore, in this embodiment, referring to Figure 3 A flange member 33 is bolted to the bending member 15 and the boundary member 14. A sealing plate member 34 is bolted to the flange member 33, so that the bending member 15, the boundary member 14 and the sealing plate member 34 form a first cavity 10. Hydraulic and electrical components and hydraulic and electrical pipelines are installed in the first cavity 10. In this way, the hydraulic and electrical components and hydraulic and electrical pipelines are not exposed in the cab, thus making the boundaries of the cab clear and realizing safe driving of the whole machine. The hydraulic and electrical components in the housing can be inspected and maintained by disassembling the sealing plate member 34.

[0061] Furthermore, in this embodiment, referring to Figure 1 The armrest surface 9 has mounting holes 35, through which additional components and buttons for other functions of the machine, such as emergency stop switches, can be added. Similarly, the wiring parts of these components are concealed within the first cavity 10.

[0062] Furthermore, in this embodiment, a flange member 33 is bolted to the first inclined plate 18 of the boundary member 14. The flange member 33 is bolted to an electrical control box (not shown in the attached figure). The electrical control box also has buttons and components with display functions. All the buttons and wiring with display functions enter the first cavity 10 through the mounting holes 35 at the curved member 15, thereby simplifying and improving the layout inside the driver's seat. This enhances driving comfort and safety within a limited driving area. Since the first inclined surface faces the seat 6, when the electrical control box is installed on the flange member 33, the buttons and components with display functions on the electrical control box face the seat 6, making it easy for the driver to observe. At the same time, by increasing or decreasing the thickness of the electrical control box, it is beneficial to optimize the comfortable operating range of the seat reference point (SIP) of the seat 6 from the electrical control box. This improves the driving experience, saves space in the driver's cabin, and the flange member 33 also enhances the sense of boundary in a small space. This layout structure ensures driving comfort and safety.

[0063] Furthermore, in this embodiment, hooks are bolted to the main body component 38 and the support component. The hooks are used to place the life pack worn by the driver. The life pack straps are hung on the hooks on the main body component 38 and the support component respectively, so that the life pack is placed stably. Therefore, the life pack does not shake when the whole machine is moving.

[0064] Furthermore, in this embodiment, reference is made to... Figure 4 The upper end of the connecting plate 41 has a recessed area 36, ​​and the edges of the first support rod 39, the second support rod 40 and the connecting plate 41 are all covered with soft components. When the driver sits on the seat 6, the recessed area 36 releases the driver's space. The soft components are made of any one of polyurethane, EPDM rubber and natural rubber, and their Shore hardness is controlled within the range of 30HA-45HA. This effectively protects the driver's head and prevents the driver's head from hitting the recessed area 36 due to vehicle bumps, further improving driving comfort.

[0065] Furthermore, in this embodiment, referring to Figure 9 and Figure 10The seat base 5 is a conical component. A second cavity is provided at the lower end of the seat base 5. This second cavity can be used to house hydraulic and electrical components, thereby optimizing the overall vehicle layout space. Furthermore, the height formed by the upper and lower surfaces of the conical component can accommodate different seat models 6. The conical component, with its varying heights, can also accommodate drivers of different heights. The lower end of the seat base 5 has a side protrusion. The upper end of the seat base 5 is called the first upper plane, and the upper end of the side protrusion is called the second upper plane. A pin is integrally connected to the front side of the first base plate 7, and a pin hole is integrally connected to the lower front end of the seat base 5. The pin hole and the pin... The axle fittings allow the seat base 5 to be rotatably connected to the first base plate 7. The first and second upper surfaces of the seat base 5 have connecting holes, which are bolted to the first base plate 7. This allows the user to lift the seat base 6 using the pin and pin hole fittings, thereby exposing the components placed in the space formed between the seat base 6 and the first base plate 7. This facilitates maintenance and repair without disassembling the seat 6, enabling the repair of hydraulic and electrical components in the vehicle without disassembling the seat 6 in the confined cab space. Furthermore, the bolted connection between the seat base 5 and the first base plate 7 ensures the stability of the connection between the first base plate 7 and the seat base 6. The bolts are removed only when the seat needs to be opened, making it quite convenient.

[0066] Furthermore, in this embodiment, referring to Figures 11-13 The door assembly 3 includes a door body and a pin hole end. The door body is bolted to the pin hole end. A pin shaft end is bolted to the front end of the main component 38, and the pin shaft end is rotatably connected to the pin hole end, allowing the door body to be rotatably connected to the main component 38. When the door assembly 3 rotates 90° along the main component 38, the minimum entrance size H of the cab is ≥ 550mm, thus meeting the safety requirements of GB21500 for trackless tire-type mining vehicles in underground mines. The door body is an L-shaped closed-loop structure formed by steel pipes. The L-shaped door body is rotatably connected to the main component 38 through the edge of its shorter side. When the door assembly 3 is closed, the L-shaped door body is parallel to the horizon through the edge of its longer side and perpendicular to the horizon through the edge of its shorter side. At this time, the minimum entrance size H ≤ 550mm, thus saving cab space. The door lock of the door assembly 3 is connected to the adjacent components of the vehicle.

[0067] Furthermore, in this embodiment, the second base plate 25 can also be served by the vehicle frame 24.

[0068] Furthermore, in this embodiment, the width of the seat surface 11 can also be in the range of 350mm-500mm.

[0069] Example 2

[0070] This embodiment provides a wet spraying machine with a trolley cab.

[0071] Reference Figures 1-13 The vehicle includes a frame 24 and a cab. The cab includes a body 1, a roof assembly 2, a door assembly 3, and a seat assembly 4. The body 1 is mounted on the frame 24, the seat assembly 4 is mounted on the body 1, the door assembly 3 is also connected to the body 1, and the roof assembly 2 is also connected to the body 1 and can cover the seat assembly 4.

[0072] The main body 1 includes a first base plate 7, a second base plate 25, a support assembly 37, and a main body component 38. Both the first base plate 7 and the second base plate 25 are bolted to the upper side of the frame 24. The second base plate 25 is located below the front side of the first base plate 7, forming a step with it. An accelerator pedal is located at the upper right corner of the second base plate 25, and an anti-slip mat 26 is laid on it. The support assembly 37 includes a first support rod 39, a second support rod 40, and a connecting plate 41. The first support rod 39 and the second support rod 40 are symmetrically arranged on both sides of the rear side of the first base plate 7. The lower ends of both the first support rod 39 and the second support rod 40 are bolted to the first base plate 7. A roof assembly 2 is inserted into the first support rod 39 and the second support rod 40, and the connecting plate... 41 is bolted between the first support rod 39 and the second support rod 40. The main component 38 is located on the left side of the first base plate 7. The main component 38 includes a skeleton 13, a boundary component 14 and a bending component 15. One end of the skeleton 13 is bolted to the side wall of the second support rod 40, and the other end extends parallel to the left side of the first base plate 7. The boundary component 14 is arranged to follow the shape of the skeleton 13. The upper end of the boundary component 14 is welded to the skeleton 13, and the lower end is welded to the left side of the first base plate 7 and the second base plate 25. The bending component 15 is shaped like a "7". The left side of the upper end of the bending component 15 is bolted to the boundary component 14, and the lower side of the bending component 15 is bolted to the first base plate 7, so that the upper surface of the bending component 15 forms the handrail surface 9. A first cavity 10 is formed between the bending component 15 and the boundary component 14. The first cavity 10 is located inside the handrail surface 9.

[0073] Seat assembly 4 includes a seat base 5 and a seat 6. The lower end of the seat base 5 is bolted to a first base plate 7, and the upper end of the seat base 5 is bolted to the seat 6. The seat 6 has a seat surface 11 with a width of 400mm. The first base plate 7 has a control box on the right side of seat assembly 4. One end of the control box is bolted to a support assembly 37, and the lower side of the other end is connected to a rod-shaped member 22. The lower end of the rod-shaped member 22 is bolted to the first base plate 7. The control box includes a flat portion 12, with a valve hole 43 on the upper side. The flat portion 12 has a third cavity 42, and a rod valve body is located inside the third cavity 42, extending from the valve hole 43 so that the rod valve body can be positioned on the flat portion 12. The flat portion 12 of the control box is 200mm-26mm higher than the seat surface 11. The control box is 0mm thick, so that the flat part 12 of the control box can be used as an armrest of the seat 6. The flat part 12 of the control box includes a front part, a middle part and a rear part of the control box. The distance between the side wall of the rear part of the control box and the edge of the seat surface 11 is B1, B1 = 100mm ± 15mm. The distance between the side wall of the middle part of the control box and the edge of the seat surface 11 is B2, B2 = 40mm ± 15mm. The distance between the side wall of the front part of the control box and the edge of the seat surface 11 is B3, B3 = 75mm ± 15mm. The armrest platform 9 is located on the left side of the seat 6. The distance between the side wall of the armrest platform 9 and the edge of the seat surface 11 is 40mm-50mm. The armrest platform 9 is also 200mm-260mm higher than the seat surface 11. The upper surface of the armrest platform 9 is flush with the upper surface of the flat part 12 of the control box 8.

[0074] When the driver is seated in seat 6, the left side of the driver is the armrest platform 9, the right side is the control box 8, and the top is the roof assembly 2. This clearly defines the different areas of the driver's seating position, enhancing the sense of boundary within the cab. Furthermore, by limiting the distance between the side of the seat surface 11 of seat 6 closest to the control box 8 and its side wall, and the distance between the other side of the seat surface 11 of seat 6 and the side wall of the armrest platform 9 of the main body 1, the driver's hips have room to move. Simultaneously, the driver can rest their elbows on the armrest platform 9 and the upper surface of the control box 8 for comfortable operation, freeing up elbow movement space and facilitating hand operation of valve stems, further improving driving comfort. The seating space is not compressed despite the reduction in the overall size of the cab as the machine's dimensions decrease. Moreover, the various parts of the control box 8... The different distances between the control box and the seat surface 11 allow for efficient use of the cab space while ensuring driver comfort. For example, the rear of the control box provides ample space for the driver's hips, preventing tension in the hip bones and muscles due to the cramped cab space, thus facilitating the extension of the thighs to the outside of the seat 6. The middle of the control box provides convenient elbow placement for the driver, while the front of the control box allows the driver's thighs and knees to extend to the sides while seated, enabling free operation of the accelerator pedal located in the notch area of ​​the anti-slip mat 26. Simultaneously, the thighs and knees, by conforming to the front of the control box, define the boundary of the accelerator pedal operation area and limit its movement, thereby enhancing driving safety. In this way, while defining space for the accelerator pedal within the cab, it also facilitates the arrangement of other control areas within the cab.

[0075] The wet spraying machine also includes common wet spraying machine structures such as a walking system, a power system, a hydraulic system, and an electrical control system. In this embodiment, the existing technology structures and positions are used, so they will not be described in detail here.

[0076] Furthermore, in this embodiment, a first groove 19 is formed on the rear side of the control box near the seat 6, such that the distance between the rear side wall of the control box and the seat 6 is greater than the distance between the middle side wall of the control box and the seat 6. A second groove 20 is formed on the front side of the control box near the seat 6, such that the distance between the front side wall of the control box and the seat 6 is greater than the distance between the middle side wall of the control box and the seat 6. This achieves a distance of B1 between the rear end of the control box 8 and the seat 6, where B1 = 100mm ± 15mm; a distance of B2 between the middle of the control box and the seat 6, where B2 = 40mm ± 15mm; and a distance of B2 between the front end of the control box and the seat 6. B3, B3 = 75mm ± 15mm, the rear of the inner curved plate allows the first groove 19 to fully release the driver's hip space when the driver sits on the seat 6, so that the hip bones and muscles are not in a tense state due to the compact space in the driver's cabin, thus making it easier for the thigh to extend to the outside of the seat 6. At the same time, the space formed by the seat 6, the inner curved plate and the upper surface of the control box 8 also releases the elbow space, making it easier for the hand to operate the valve stem. The second groove 20 allows the driver's thigh and knee joints to extend to the front and outside of the inner curved plate when sitting on the seat 6, so that the lower leg and foot can be operated freely.

[0077] Furthermore, in this embodiment, referring to Figure 1 and Figure 7 An inverted "L"-shaped bending adjustment member 23 is bolted to the lower left side of the control box 8. The bending adjustment member 23 includes a horizontal plate portion 27 and a vertical plate portion 28. The left end of the horizontal plate portion 27 is integrally formed with the upper end of the vertical plate portion 28. The horizontal plate portion 27 of the bending adjustment member 23 is bolted to the lower side of the control box 8. The vertical plate portion 28 of the bending adjustment member 23 is bolted to a threaded hole plate 44. The vertical plate portion 28 of the bending adjustment member 23 is bolted to the support assembly 37 through the threaded hole plate 44. A rod-shaped member 22 is bolted to the lower right side of the control box. The lower end of the rod-shaped member 22 is bolted to the first base plate 7 of the main body portion 1.

[0078] Furthermore, in this embodiment, a horizontal elongated hole is provided on the horizontal plate portion 27, and a vertical elongated hole is provided on the vertical plate portion 28. The values ​​of B1, B2, and B3 can be adjusted appropriately through the horizontal elongated hole of the bending adjustment member 23, and the installation height of the control box 8 can be adjusted appropriately through the vertical elongated hole of the bending adjustment member 23. This can meet the needs of drivers of different heights, so that the values ​​of B1, B2, and B3 can all be adjusted by ±15mm.

[0079] Furthermore, in this embodiment, referring to Figure 8 The control box 8 has an inspection hole 29 on the side near the seat 6. The inspection hole 29 facilitates the installation and maintenance of the rod valve body pipeline placed inside the control box 8. The control box 8 also has a blind plate component 30 at the inspection hole 29, so that the inspection hole 29 is connected to the blind plate component 30.

[0080] Furthermore, in this embodiment, the tilting portion 21 of the control box 8 also includes an inclined portion 21, which is integrally formed with the flat portion 12. The upper plane of the flat portion 12 is arranged at an angle α with the tilting portion 21, where the angle α is in the range of 100-115°. The width of the tilting portion 21 is smaller than the width of the flat portion 12 of the control box 8, and the upper width of the tilting portion 21 is smaller than the lower width of the control box 8. An instrument panel is bolted to one end of the tilting portion 21 near the flat portion 12, and the instrument panel is arranged at an angle α with the flat portion 12. Commonly used buttons are located at the lower end of the instrument panel. Less frequently used electrical components, as well as those with display functions, are positioned at the upper part of the instrument panel. This arrangement uses an α angle to represent the distance between the instrument panel and the seat reference point (SIP) of the seat 6, making the lower part of the instrument panel closer to the seat reference point (SIP) of the seat 6. This allows the driver to operate frequently used buttons without raising their elbow. Compared with existing technologies, this ensures the comfort of the control area, improves control efficiency, and reduces fatigue. Meanwhile, the upper part of the instrument panel is farther and higher than the seat reference point (SIP) of the seat 6, making it easier for the driver to observe electrical components with display functions, thereby reducing driver visual fatigue.

[0081] Furthermore, in this embodiment, referring to Figure 1 and Figure 6 The boundary component 14 includes an upper boundary 31 and a lower boundary 32. The upper boundary 31 includes a first horizontal plate 16, a first vertical plate 17, and a first inclined plate 18. The first horizontal plate 16 is arranged parallel to the connecting plate 41. The rear end of the first horizontal plate 16 is bolted to the side wall of the support component 37, and the other end is integrally formed with the first vertical plate 17. The first vertical plate 17 is arranged perpendicular to the first horizontal plate 16. The first inclined plate 18 is integrally formed with the end of the first vertical plate 17 away from the first horizontal plate 16, and there is an angle between the first inclined plate 18 and the first vertical plate 17, with the angle being greater than 90°. The upper end of the lower boundary 32 is integrally formed with the lower end of the upper boundary 31, and the lower end of the lower boundary 32 is welded to the first base plate 7. An electrical control box is provided on the first inclined plate 18, which not only provides more space for the driver's left hand, but also allows the driver to install the electrical control box through the first inclined plate 18, making it convenient for the driver to observe and operate.

[0082] Furthermore, in this embodiment, referring to Figure 3A flange member 33 is bolted to the bending member 15 and the boundary member 14. A sealing plate member 34 is bolted to the flange member 33, so that the bending member 15, the boundary member 14 and the sealing plate member 34 form a first cavity 10. Hydraulic and electrical components and hydraulic and electrical pipelines are installed in the first cavity 10. In this way, the hydraulic and electrical components and hydraulic and electrical pipelines are not exposed in the cab, thus making the boundaries of the cab clear and realizing safe driving of the whole machine. The hydraulic and electrical components in the housing can be inspected and maintained by disassembling the sealing plate member 34.

[0083] Furthermore, in this embodiment, referring to Figure 1 The armrest surface 9 has mounting holes 35, through which additional components and buttons for other functions of the machine, such as emergency stop switches, can be added. Similarly, the wiring parts of these components are concealed within the first cavity 10.

[0084] Furthermore, in this embodiment, a flange member 33 is bolted to the first inclined plate 18 of the boundary member 14. The flange member 33 is bolted to an electrical control box (not shown in the attached figure). The electrical control box also has buttons and components with display functions. All the buttons and wiring with display functions enter the first cavity 10 through the mounting holes 35 at the curved member 15, thereby simplifying and improving the layout inside the driver's seat. This enhances driving comfort and safety within a limited driving area. Since the first inclined surface faces the seat 6, when the electrical control box is installed on the flange member 33, the buttons and components with display functions on the electrical control box face the seat 6, making it easy for the driver to observe. At the same time, by increasing or decreasing the thickness of the electrical control box, it is beneficial to optimize the comfortable operating range of the seat reference point (SIP) of the seat 6 from the electrical control box. This improves the driving experience, saves space in the driver's cabin, and the flange member 33 also enhances the sense of boundary in a small space. This layout structure ensures driving comfort and safety.

[0085] Furthermore, in this embodiment, hooks are bolted to the main body component 38 and the support component. The hooks are used to place the life pack worn by the driver. The life pack straps are hung on the hooks on the main body component 38 and the support component respectively, so that the life pack is placed stably. Therefore, the life pack does not shake when the whole machine is moving.

[0086] Furthermore, in this embodiment, reference is made to... Figure 4The upper end of the connecting plate 41 has a recessed area 36, ​​and the edges of the first support rod 39, the second support rod 40 and the connecting plate 41 are all covered with soft components. When the driver sits on the seat 6, the recessed area 36 releases the driver's space. The soft components are made of any one of polyurethane, EPDM rubber and natural rubber, and their Shore hardness is controlled within the range of 30HA-45HA. This effectively protects the driver's head and prevents the driver's head from hitting the recessed area 36 due to vehicle bumps, further improving driving comfort.

[0087] Furthermore, in this embodiment, referring to Figure 9 and Figure 10 The seat base 5 is a conical component. A second cavity is provided at the lower end of the seat base 5. This second cavity can be used to house hydraulic and electrical components, thereby optimizing the overall vehicle layout space. Furthermore, the height formed by the upper and lower surfaces of the conical component can accommodate different seat models 6. The conical component, with its varying heights, can also accommodate drivers of different heights. The lower end of the seat base 5 has a side protrusion. The upper end of the seat base 5 is called the first upper plane, and the upper end of the side protrusion is called the second upper plane. A pin is integrally connected to the front side of the first base plate 7, and a pin hole is integrally connected to the lower front end of the seat base 5. The pin hole and the pin... The axle fittings allow the seat base 5 to be rotatably connected to the first base plate 7. The first and second upper surfaces of the seat base 5 have connecting holes, which are bolted to the first base plate 7. This allows the user to lift the seat base 6 using the pin and pin hole fittings, thereby exposing the components placed in the space formed between the seat base 6 and the first base plate 7. This facilitates maintenance and repair without disassembling the seat 6, enabling the repair of hydraulic and electrical components in the vehicle without disassembling the seat 6 in the confined cab space. Furthermore, the bolted connection between the seat base 5 and the first base plate 7 ensures the stability of the connection between the first base plate 7 and the seat base 6. The bolts are removed only when the seat needs to be opened, making it quite convenient.

[0088] Furthermore, in this embodiment, referring to Figures 11-13The door assembly 3 includes a door body and a pin hole end. The door body is bolted to the pin hole end. A pin shaft end is bolted to the front end of the main component 38, and the pin shaft end is rotatably connected to the pin hole end, allowing the door body to be rotatably connected to the main component 38. When the door assembly 3 rotates 90° along the main component 38, the minimum entrance size H of the cab is ≥ 550mm, thus meeting the safety requirements of GB21500 for trackless tire-type mining vehicles in underground mines. The door body is an L-shaped closed-loop structure formed by steel pipes. The L-shaped door body is rotatably connected to the main component 38 through the edge of its shorter side. When the door assembly 3 is closed, the L-shaped door body is parallel to the horizon through the edge of its longer side and perpendicular to the horizon through the edge of its shorter side. At this time, the minimum entrance size H ≤ 550mm, thus saving cab space. The door lock of the door assembly 3 is connected to the adjacent components of the vehicle.

[0089] Furthermore, in this embodiment, the width of the seat surface 11 can also be in the range of 350mm-500mm.

[0090] Furthermore, in this embodiment, the second base plate 25 can also be served by the vehicle frame 24.

[0091] Furthermore, in this embodiment, the cab can also be connected to the frame 24 of the shovel trolley, loader, rock drilling trolley, etc., through the first base plate 7 of the main body part 1 and the second base plate 25 of the main body component 38, so that the cab can meet the use of different types of underground mining equipment.

[0092] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0093] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
