Description

Technical Field

[0001] The present application relates to the technical field of underground loaders, and particularly to a cab of an underground loader. Background Art

[0002] Existing underground loaders are mainly used in underground mine roadways to mainly load and transport loose materials after blasting. Usually, the specifications and models of underground loaders are determined by their bucket capacities. Currently, common domestic and foreign models include: 1m 3 underground loader, 2m 3 underground loader, 2.5m 3 underground loader, 3m 3 underground loader... Due to the restrictions of the cross-sectional dimensions of tunnels and underground roadways, currently, 8m 3 loaders are already the largest models applied at home and abroad.

[0003] For underground loaders with a capacity of 2.5m 3 and below, they mainly serve the roadway operations of small and medium-sized cross-sections with a width of 3.0 meters × a height of 3.0 meters and below. Limited by the roadway conditions, when designing the overall scheme of the loader, its overall parameters should be considered first, such as the overall length, width, and height; secondly, on the premise of ensuring the functional structure devices, the external dimensions should be reduced as much as possible to ensure the passability of the roadway.

[0004] Therefore, on the premise of ensuring functional structure devices such as the bucket, working arm, power and transmission systems, etc., the space of the cab is compressed to ensure the functionality of the whole machine and the safety of driving in underground roadways; however, due to the compression of the cab space, the narrow space has many restrictions on the driver, such as the legs cannot be fully stretched, or the body cannot sit straight and stretch completely, which makes it inconvenient for the driver to drive the loader in the cab and affects the driver's operation.

[0005] Therefore, there is room for further improvement in the cab settings of existing small underground loaders. Utility Model Content

[0006] In view of the above technical problem that for small underground loaders in small and medium-sized cross-section roadway operations in the above-mentioned existing technologies, the cab of the underground loader is compressed due to roadway conditions, resulting in inconvenient driving for the driver in the narrow driving space, the present application provides a cab of an underground loader, which reasonably arranges the components in the cab, so that the restrictions on the driver in the cab are reduced, and the influence of the narrow driving space on the driver is reduced.

[0007] The present application provides an underground loader cab, which includes a frame side plate, a ceiling and a frame bottom plate. The ceiling is connected to the upper end of the frame side plate, and the frame bottom plate is connected to the bottom of the frame side plate. A driving space is formed among the frame side plate, the ceiling and the frame bottom plate;

[0008] It further includes a seat assembly, a pedal mounting assembly and a console. The seat assembly, the pedal mounting assembly and the console are arranged in the driving space;

[0009] The seat assembly includes a seat and a bracket. One end of the bracket is connected to the frame bottom plate, and the other end is connected to the seat. Wherein, there is a first included angle α between the upper end surface of the bracket and the frame bottom plate, and 0° < α < 90°.

[0010] Compared with the prior art, in the underground loader cab of the present application, by setting the upper end surface of the bracket for supporting the seat to be inclined, with the frame bottom plate as the reference plane, there is a first included angle between the upper end surface of the bracket and the frame bottom plate, and the angle of the first included angle is greater than 0 degree and less than 90 degrees. When the seat is installed on the bracket, since the connecting surface between the bracket and the seat is inclined, the seat is also inclined. When the driver sits on the seat, the driver's buttocks are lower than the knees, so that the distance between the buttocks and the ceiling is greater than the distance between the knees and the ceiling, facilitating an increase in the distance from the driver's head to the cab ceiling. Therefore, even if the cab space is compressed, there is still sufficient reserved space between the driver's head and the cab ceiling to ensure the driving comfort of the driver.

[0011] Preferably, the pedal mounting assembly is arranged on the side facing the seat. The pedal mounting assembly includes a brake pedal base, and the brake pedal base is arranged on the frame bottom plate;

[0012] There is a second included angle θ between the center line of the brake pedal base and the center line of the seat, and 0° < θ < 90°.

[0013] Preferably, a first installation groove is provided on the frame bottom plate, and the first installation groove is used for installing the brake pedal base;

[0014] The upper surface of the end of the brake pedal close to the seat is lower than the upper end surface of the frame bottom plate, and the upper surface of the end of the brake pedal far from the seat is higher than the upper end surface of the frame bottom plate;

[0015] Wherein, 10° ≤ θ ≤ 15°.

[0016] Preferably, the pedal mounting assembly further includes an accelerator pedal base, and the accelerator pedal base is arranged on the frame bottom plate;

[0017] There is a third included angle β between the upper end surface of the throttle pedal base and the frame bottom plate, where 0° < β < 90°;

[0018] and / or,

[0019] There is a fourth included angle δ between the center line of the throttle pedal base and the center line of the seat, where 0° < δ < 90°.

[0020] Preferably, the third included angle β is set as: 8° ≤ β ≤ 12°;

[0021] The fourth included angle δ is set as: 10° ≤ δ ≤ 12°.

[0022] Preferably, the center console is arranged above the pedal mounting assembly;

[0023] Wherein, there is a fifth included angle γ between the upper end surface of the center console and the frame bottom plate, where 0° γ < 90°.

[0024] Preferably, the fifth included angle γ is set as: 10° ≤ γ ≤ 20°.

[0025] Preferably, it further includes a mounting seat and a connecting piece. One end of the mounting seat is connected to the frame side plate, and the other end is connected to the center console;

[0026] Wherein, there is a mounting hole on the center console, and one end of the connecting piece passes through the mounting hole and is connected to the mounting seat.

[0027] Preferably, the center console includes an arc portion and a straight portion, and the arc portion is located at both ends of the straight portion;

[0028] Wherein, the end face of the arc portion close to the seat is arc-shaped, and the end face of the straight portion close to the seat is straight-shaped.

[0029] Preferably, the distance between the vertex of the arc portion close to the seat and the vertex of the straight portion close to the seat is set within the range of 30 mm to 50 mm.

[0030] Preferably, it further includes a top foam strip, and the top foam strip is connected to the outer wall of the bottom of the center console;

[0031] and / or,

[0032] It further includes an electric fan, and the electric fan is connected to the inner wall of the ceiling and is used to blow air towards the seat direction.

[0033] Preferably, the first included angle α is set as: 5° ≤ α ≤ 10°.

[0034] A cab of an underground loader of the present application has at least the following technical effects:

[0035] 1. By setting the first angle α between the upper end face of the bracket and the frame bottom plate within 5° ≤ α ≤ 10°, the driver's buttocks to knees can also be inclined, increasing the reserved space between the head and the ceiling, ensuring the comfort of the driver in the cab; at the same time, the vertical distance between the driver's knees and heels is compressed, causing the driver's sole to form an angle with the ground. Thus, when the width direction of the whole machine is compressed, the comfort of the driver's operation of the accelerator pedal and brake pedal on the legs can still be maintained;

[0036] 2. The rear end of the brake pedal base sinks below the frame bottom plate, and the front end of the brake pedal base is placed on the frame bottom plate. In this way, after the brake pedal is installed on the brake pedal base, the brake pedal fits more closely to the driver's sole, thereby increasing the comfort of the driver's operation;

[0037] 3. By setting the fifth angle γ between the console tabletop and the frame bottom plate between 10° and 20°, the highest points of the control handles and bucket control handles on the console are lowered and close to the driver, and the highest points of the control handles of the drive train and bucket control handles are kept within the comfortable operation area range relative to the SIP of the seat. Therefore, when the driver sits on the seat and operates the control handles of the drive train and bucket control handles, the hands and arms will not feel fatigued due to the compression of the internal space of the cab;

[0038] 4. By setting installation holes on the console, the connection position between the console and the mounting seat can be adjusted through the installation holes, and then the height of the console can be adjusted, so as to adapt to the operation of drivers of different heights;

[0039] 5. By setting the distance between the end vertex of the arc part of the console and the end vertex of the straight part within the range of 30 mm - 50 mm, a comfortable activity space is left for the driver's trunk, as well as space for the legs to stretch and translate;

[0040] 6. By setting a top foam rubber strip at the bottom of the console, the top foam rubber strip can buffer and offset the impact force between the legs and the bottom of the console, preventing the legs from feeling pain and improving the comfort of operation.

[0055] Those skilled in the art should understand that in the disclosure of the present application, the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present application.

[0056] The present application will be further described in detail below with reference to the accompanying drawings. See Figures 1 to 7 the description.

[0057] The present application provides a cab 1 for an underground loader (hereinafter referred to as the cab), which is used in medium and small-sized underground loaders and is suitable for medium and small-sized underground loaders operating in roadways with a cross-section of less than 3.0 meters in width × 3.0 meters in height. Due to the limitations of roadway conditions, the cab 1 is designed so that the driver can operate conveniently in a narrow driving space.

[0058] Specifically, as Figures 1 to 4 shown, the cab 1 of the present application includes a frame side plate 11, a roof 13, and a frame bottom plate 12. The roof 13 is connected to the upper end of the frame side plate 11. The roof 13 is an n-shaped rectangular structure. The lower end of the roof 13 is connected to the frame side plate 11. The frame side plate 11 is the back plate of the cab 1. The frame bottom plate 12 is connected to the bottom of the frame side plate 11. Usually, the frame bottom plate 12 is parallel to the horizontal plane. The frame side plate 11 extends in the vertical direction. The frame bottom plate 12 is basically a flat plate structure. A driving space is formed between the frame side plate 11, the roof 13, and the frame bottom plate 12; as Figure 1 、 Figure 2 shown, the cab 1 further includes a seat assembly 15, a pedal mounting assembly 14, and a center console 16. The seat assembly 15, the pedal mounting assembly 14, and the center console 16 are arranged in the driving space. The seat assembly 15, the pedal mounting assembly 14 are connected to the frame bottom plate 12. The seat assembly 15 faces away from the frame side plate 11. The seat assembly 15 faces the direction of the pedal mounting assembly 14. The seat assembly 15 and the pedal mounting assembly 14 are arranged at intervals. The center console 16 is arranged above the pedal mounting assembly 14. The tabletop of the center console 16 is used to mount the bucket control handle;

[0059] Among them, as Figure 1 shown, the seat assembly 15 includes a seat 151 and a bracket 152. The bottom of the bracket 152 is connected to the frame bottom plate 12. The upper end of the bracket 152 is connected to the seat 151. In the present application, with the frame bottom plate 12 as the reference plane, there is a first angle α between the upper end face of the bracket 152 and the frame bottom plate 12, where 0° < α < 90°. That is, the end face of the bracket 152 connected to the seat 151 is inclined relative to the frame bottom plate 12, and then the upper end face for contact of the seat 151 is also inclined. When the driver sits on the seat 151, the driver's buttocks are lower than the knees, so that the reserved space between the driver's head and the roof 13 is larger, thereby improving the driving comfort of the driver.

[0060] Further, in the present application, the first included angle α is set as: 5° ≤ α ≤ 10°. Within this range, it is possible to improve the reserved space from the driver's head to the ceiling 13 as much as possible while ensuring the driver's comfort, and it can also ensure that the driver can drive smoothly and naturally.

[0061] Further, as Figure 1 shown, the distance between the front end face of the seat 151 and the front end face of the bracket 152 is L1, and L1 is set within the range of 180 mm - 200 mm. When the driver's legs need to curl up and rest, the calves and feet are retracted to the lower end of the seat 151 to rest the calves and feet and relieve fatigue.

[0062] It should be noted that in the present application, the distance between the upper surface of the front end of the seat 151 and the frame bottom plate 12 is L2, where 390 mm ≤ L2 ≤ 450 mm. In this way, when the driver sits on the seat 151, the included angle between the thigh and the frame bottom plate 12 is the same as the first included angle, making the buttocks low and the knees high, thereby compressing the vertical distance between the driver's knees and heels. That is, in the natural state, the driver's calves are inclined to the vertical direction, and at the same time, the driver's sole forms an included angle with the ground, so that the driver's sole can better fit the pedal, facilitating the driver to control the pedal and improving the convenience of use and operation comfort.

[0063] It should be noted that due to the compression of the driving space, a standard seat 151 with a seat width of 450 mm cannot be used. Preferably, a seat 151 with a seat width of 400 mm is used.

[0064] In another alternative embodiment of the present application, the pedal mounting assembly 14 is further expanded; as Figure 3 shown, the pedal mounting assembly 14 is located on the side facing the seat 151. The pedal mounting assembly 14 includes a brake pedal base 141 and an accelerator pedal base 142. The brake pedal base 141 is used to mount the brake pedal, and the accelerator pedal base 142 is used to mount the accelerator pedal; both the brake pedal base 141 and the accelerator pedal base 142 are provided on the frame bottom plate 12, and the brake pedal base 141 and the accelerator pedal base 142 are spaced apart; taking the center line of the seat 151 as the reference line, the brake pedal base 141 and the accelerator pedal base 142 are located on both sides of the center line of the seat 151. In this embodiment, there is a second included angle θ between the center line of the brake pedal base 141 and the center line of the seat 151, where 0° < θ < 90°; there is a fourth included angle δ between the center line of the accelerator pedal base 142 and the center line of the seat 151, where 0° < δ < 90°. In this way, when the driver sits on the seat 151, the brake pedal base 141 and the accelerator pedal base 142 are located on the extension line of the driver's legs, facilitating the driver to step on.

[0065] Furthermore, as Figure 3 shown, the third included angle θ is set to 10° ≤ θ ≤ 15°. In this way, the connection line at the intersection of the center line of the brake pedal base 141 and the SIP center line of the seat 151 intersects, and the extension line of the side contour of the seat 151 on the side where the brake pedal base 141 is located intersects the midpoint of the front end of the brake pedal base 141, and the included angle between the extension line of the side contour of the seat 151 and the center line of the brake pedal base 141 is the same as the third included angle. Subsequently, when the driver in the cab 1 operates the brake pedal, the part from the hip to the knee (thigh) always remains in contact with the seat of the seat 151, and will not be suspended outside the seat width of the seat 151 due to the reduction of the seat width of the seat 151, still ensuring the driving comfort of the driver.

[0066] As Figure 3 shown, the fourth included angle δ is set to 10° ≤ δ ≤ 12°. The size of the fourth included angle between the center line of the accelerator pedal base 142 and the center line of the seat 151 is set within the range of 10° - 12°. When the accelerator pedal is installed on the accelerator pedal base 142, it can avoid interference between the accelerator pedal and the inner wall of the front frame. The cab 1 of this embodiment can compress a certain space and provide the extruded space for the front frame to use, thereby avoiding interference between the front frame and the rear frame during the whole machine turning.

[0067] Furthermore, as Figure 2 shown, a first installation groove is provided on the frame bottom plate 12. The first installation groove is used to install the brake pedal base 141. The upper surface of the end of the brake pedal close to the seat 151 is lower than the upper end surface of the frame bottom plate 12, and the upper surface of the end of the brake pedal far from the seat 151 is higher than the upper end surface of the frame bottom plate 12. Thus, the rear end of the brake pedal base 141 sinks below the frame bottom plate 12, and the front end of the brake pedal base 141 is placed on the frame bottom plate 12. In this way, when the brake pedal is installed on the brake pedal base 141, the angle of the brake pedal fits the included angle formed by the driver's sole and the ground, thereby ensuring the driving comfort.

[0068] Furthermore, as Figure 4 、 Figure 5 shown, there is a third included angle β between the upper end surface of the accelerator pedal base 142 and the frame bottom plate 12, where 0° < β < 90°. That is, the accelerator pedal base 142 is set to be inclined on the frame bottom plate 12, which can increase the fit with the driver's sole, facilitate the driver to step on the accelerator pedal, and the driving comfort of the driver is better.

[0069] Preferably, the third included angle β is set within the range of 8° ≤ β ≤ 12°. Such a range makes the contact between the driver's sole and the accelerator pedal more comfortable and the controllability better.

[0070] In another alternative embodiment of the present application, the center console 16 is further described; as Figure 1 and Figure 2 and Figure 4 shown, the cab 1 further includes a mounting seat 17 and a connecting member 164. The lower end of the mounting seat 17 is connected to the frame bottom plate 12, and the upper end of the mounting seat 17 near one end of the seat 151 is connected to the center console 16 through the connecting member 164; the mounting seat 17 is in an inverted L shape, and the mounting seat 17 includes a vertical plate and a horizontal plate. The horizontal plate is connected to the upper end of the vertical plate, and the included angle between the horizontal plate and the vertical plate is 90 degrees. The horizontal plate is parallel to the frame bottom plate 12, and the center console 16 is connected to the horizontal plate; the overall height of the mounting seat 17 in the vertical direction is lower than that of the frame side plate 11, that is, there is a large distance between the top of the mounting seat 17 and the ceiling 13, so that the route in front of the driver will not be blocked. As Figure 7 shown, one end of the center console 16 close to the mounting seat 17 is provided with a mounting hole 161, and one end of the connecting member 164 passes through the mounting hole 161 and is connected to the mounting seat 17. The connecting member 164 is a bolt. The center console 16 can adjust the connection position with the mounting seat 17 through the mounting hole 161, and then can adjust the height of the center console 16, so as to adapt to the operation of drivers of different heights.

[0071] Further, as Figure 4 shown, there is a fifth included angle γ between the upper end surface of the center console 16 and the frame bottom plate 12, where 0° < γ < 90°. That is, in this embodiment, the center console 16 is inclined, so that the table top of the center console 16 is inclined towards the seat 151 direction, so that the highest points of the control handle and the bucket control handle on the center console 16 are lowered and close to the driver, and the highest points of the transmission system handle and the bucket control handle are kept within the comfortable operation area relative to the SIP of the seat 151. When the driver sits on the seat 151 and operates the transmission system control handle and the bucket control handle, the hands and arms will not feel fatigued due to the compression of the internal space of the cab 1.

[0072] Preferably, the fifth included angle γ is set in the range of 10° ≤ γ ≤ 20°. Such a range can ensure the driving comfort of the driver while ensuring safe operation and will not overly compress the arm extension space.

[0073] Further, as Figure 2 and Figure 6As shown in the figure, the center console 16 includes an arc portion 162 and a straight section portion 163. The arc portion 162 is symmetrically arranged at both ends of the straight section portion 163 along the center line of the straight section portion 163. Among them, the end face of the arc portion 162 close to the seat 151 is arc-shaped, and the end face of the straight section portion 163 close to the seat 151 is straight. The control handle is arranged on the two arc portions 162. Among them, the distance between the end vertex of the arc portion 162 close to the seat 151 and the end vertex of the straight section portion 163 close to the seat 151 is set within the range of 30 mm to 50 mm, so as to leave a comfortable activity space for the driver's trunk and the stretching and translation space for the legs.

[0074] Further, as Figure 2 , Figure 6 shown in the figure, the cab 1 further includes a top foam strip 19. The top foam strip 19 is connected to the outer wall of the bottom of the center console 16, that is, the top foam strip 19 is arranged on the lower end face of the center console 16. The top foam strip 19 can wrap the R corner or the tip of the lower end face of the center console 16. When the driver's leg moves and collides with the center console 16, the top foam portion of the top foam strip 19 is compressed and buffered to offset the impact force between the leg and the bottom end of the front wall of the center console 16, so that the leg does not feel pain and the comfort of operation is improved.

[0075] In another alternative embodiment of the present application, the cab 1 is further expanded. As Figure 1 , Figure 2 shown in the figure, the cab 1 further includes an electric fan 18. The electric fan 18 is connected to the inner side wall of the ceiling 13. The electric fan 18 faces the SIP of the seat 151. The electric fan 18 is used to blow air towards the seat 151, so as to provide a relatively comfortable driving environment for the driver.

[0076] Further, the electric fan 18 is arranged at the right front corner or the right rear corner of the inner top of the ceiling 13, so as not to affect the driver's driving line of sight. When the electric fan 18 swings, it can cover a large range of the interior space of the cab, improving the comfort of operation. When the electric fan 18 is arranged at the right front corner of the inner top of the ceiling 13, a monitoring screen of a camera is installed at the right rear corner of the inner top of the ceiling 13. Similarly, the monitoring screen of the camera faces the SIP of the seat 151, so that the driver can observe the monitoring screen of the camera at a comfortable angle and does not affect the driver's driving line of sight. The same is true vice versa, so it will not be elaborated here.

[0077] The above has introduced the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the present application and its core idea. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
