Description

Cab and underground scraper

Technical Field

The invention relates to the field of engineering machinery, in particular to a cab and an underground scraper.

Background

The underground scraper generally works in a mine, the working condition of the mine is very bad, and pumice sometimes falls off from the top of the mine. The underground mine has steep hillside, more bends and uneven road, and can be turned over by carelessness. Meanwhile, the safety performance requirements for underground scrapers in the industry are gradually increased, and the cab is required to meet the performance requirements for preventing rolling and falling objects. Rollover protection means that in the event of a rollover, the cab does not roll or rolls only over a small angle. The object falling prevention means that the object falling cannot fall through the cab when the object falling on the cab falls. Therefore, there is a need in the art to design an underground scraper that can meet the requirements of anti-rolling and anti-falling performance.

However, the inventor found that since the working environment of the underground scraper is a tunnel with a narrow space, the width and height of the body of the underground scraper are strictly limited, and the space of the cab is small, and it is difficult to make a closed structure like a large scraper on the ground. Meanwhile, the safety and the comfort of driving directly influence the misoperation and the working efficiency of a driver, so that the driver cab meeting the requirements is difficult to design under the limited space.

In the related technology, in order to meet the performance requirements of rolling resistance and falling resistance, a cab of an underground scraper uses profile steel welding as a framework, and a thick steel plate is welded outside the cab; or the cab of the underground scraper is made into a semi-closed structure so as to meet the requirement of large visual field.

The inventor finds that the prior art has at least the following problems: because the width and the height of the body of the underground carry scraper are strictly limited, the space of the cab is small, the size requirement is strict, the space of the cab is reduced by adopting the profile steel as the cab framework, the comfort of a driver is seriously influenced, the working efficiency is reduced, and the probability of misoperation is improved; the semi-closed structure can not meet the performance requirement of falling prevention.

Detailed Description

The technical solution provided by the present invention will be explained in more detail with reference to fig. 1 to 12.

Herein, the top, bottom, front, rear, left, and right orientations are defined in terms of the direction in which the driver operates.

The embodiment of the invention provides a cab, which comprises a ceiling plate assembly 1, a bottom plate assembly 2, a first side plate assembly 3, a second side plate assembly 4, a back plate assembly 5 and a front windshield plate assembly 6. The ceiling plate component 1 is positioned on the top of the cab; the bottom plate assembly 2 and the ceiling plate assembly 1 are arranged at intervals and are positioned at the bottom of the cab; a first side panel assembly 3 is arranged between the ceiling panel assembly 1 and the floor panel assembly 2; the second side plate assembly 4 is arranged at a distance from the first side plate assembly 3 and is also arranged between the ceiling plate assembly 1 and the bottom plate assembly 2; the back plate assembly 5 is also arranged between the ceiling plate assembly 1 and the bottom plate assembly 2; the front wind deflector assembly 6 is also arranged between the ceiling plate assembly 1 and the floor plate assembly 2; the front windshield assembly 6 is spaced apart from the back plate assembly 5. Wherein, the ceiling board component 1, the bottom board component 2, the side board component, the back board component 5 and the front wind shield component 6 jointly enclose a closed space.

The cab provided by the embodiment of the invention is of a closed structure, so that the falling object prevention performance is good, and the falling objects cannot enter the closed cab under the condition of falling objects, so that the safety of the cab is effectively improved; and the cab does not need to be separately provided with a framework formed by welding profile steel, so that the space size inside the cab is large, a driver has enough operation space, the comfort of the driver is greatly improved, the working efficiency is improved, and the probability of misoperation is reduced.

Referring to fig. 1, in some embodiments, the cab is configured to have a top cross-sectional dimension that is greater than a bottom cross-sectional dimension. The cab is relatively wide in the upper half and relatively narrow in the lower half as viewed from the front view. The design gives consideration to the structural stability and the impact resistance of the cab under the premise of increasing the space in the cab, so that the cab has good rolling prevention and falling prevention performances. The requirements of preventing rolling and falling are as follows: the cab has sufficient strength and rigidity to ensure that the cab is not damaged or deformed too much under the continuous action of lateral, longitudinal and vertical loads so as to protect a vehicle driver from being injured by invasion; and certain deformation energy absorption capacity is required to reduce the impact on the driver.

The specific structure of each part of the cab will be described in detail below.

The ceiling panel assembly 1 is the topmost part of the cab and the ceiling panel assembly 1 serves to prevent high-altitude falling objects from entering the cab. The ceiling plate component 1 covers the tops of the first side plate component 3, the second side plate component 4, the front wind shield component 6 and the back plate component 5. The first side plate component 3, the second side plate component 4, the front windshield plate component 6 and the back plate component 5 jointly enclose a shape with an opening at the top and the bottom. The size of the ceiling panel assembly 1 is larger than the size of the top of the opening, which results in a larger protected area of the ceiling panel.

Referring to fig. 1-4, 7, and 8, and particularly fig. 7 and 8, in some embodiments, the ceiling panel assembly 1 includes a ceiling panel 101, the ceiling panel 101 being configured to be bent. The top plate 101 may be formed by bending a single plate. The size of the top plate 101 is larger than the top end size of an opening surrounded by the first side plate assembly 3, the front wind shield plate assembly 6, the second side plate assembly 4 and the back plate assembly 5, and the top end of the opening is covered by the top plate 101; the edge of the top plate 101 on the side of the back plate assembly 5 is inclined downwards towards the back plate and bent so that falling objects slide off the inclination of the top plate 101.

In some embodiments, the ceiling panel assembly 1 has a thickness of 13.5mm to 14.5mm, specifically 13.5mm, 14mm, 14.5mm. Through finite element analysis and calculation, the parameters can provide the rigidity and the light weight required by the cab to the maximum extent.

Referring to fig. 7 and 8, the back plate assembly 5 includes a first barrier plate 51 and a second barrier plate 52. The first and second shutters 51 and 52 extend downward along the bottom edge of the top plate 101. The first baffle 51 is integral with the top plate 101, and the angle α between the first baffle 51 and the top plate 101 is 128 ° to 130 °. The second baffle plate 52 and the first baffle plate 51 are also integrated, and the included angle beta between the second baffle plate 52 and the first baffle plate 51 is 167-170 degrees.

The first and second flaps 51 and 52 of the ceiling panel assembly 1 and the back panel assembly 5 are integrally formed by bending, and are bent twice to obtain a desired shape. The included angle alpha is 128-130 degrees, and the included angle beta is 167-170 degrees. Through finite element analysis and calculation, the bending structure and the bending angle are in the optimal structure type, and the rigidity and the energy absorption capacity required by the cab can be provided to the maximum extent.

Referring to fig. 9, the back plate assembly 5 further includes a pasting plate 53, and the pasting plate 53 is pasted with the first baffle 51 and the second baffle 52 and is welded and fixed. The first baffle 51, the second baffle 52 and the flitch 53 are welded and fixed, and the surfaces are jointed.

The sticking board 53 is an integrally bent thin board, and the thickness thereof is, for example, 7.5mm to 8.5mm, specifically, 7.5mm, 8mm, and 8.5mm. The left lower side and the right upper side are bent at the edges, so that the flitch 53 is firmly welded with the cab, and the first baffle 51 and the second baffle 52 are strengthened and have impact resistance. The rear flitch 53 is subjected to finite element topological optimization, the upper left side and the lower right side of the part which has little contribution to the strength are removed, inner grooves are formed in the middle position and one side of the top of the flitch 53 in the height direction of the flitch 53, the weight of the flitch 53 is reduced through the inner grooves, the weight reduction purpose is achieved while the strength of the flitch 53 is not reduced, and the weight of the whole vehicle is effectively reduced while the rigidity strength of a cab is ensured.

Above-mentioned technical scheme through setting up flitch 53 for the protection architecture (ROPS for short) atress of overturning of whole driver's cabin is more reasonable, and it is less to warp, can provide sufficient bearing capacity and energy absorption.

In some embodiments, the thickness of the ceiling board assembly 1 is also the thickness of the top board 101, the first baffle 51 and the second baffle 52, that is, the thickness of the first baffle 51 and the second baffle 52 is also 13.5mm to 14.5mm, such as 13.5mm, 14mm and 14.5mm. The ceiling plate assembly 1 with the thickness is high in bearing capacity, the thickness of the ceiling plate assembly 1 is matched with the structural shape of the ceiling plate assembly, the safety performance that a bearing cab meets standard regulations can be met, and meanwhile the weight is the lightest scheme. Through the verification of a heavy hammer falling object test, because the ceiling plate component 1 adopts the structure and the parameters, after the heavy hammer falls, the deformation of the top of the cab is smaller, the heavy hammer does not puncture the ceiling plate component 1 of the cab, and the performance of the ceiling plate component 1 far exceeds the falling object standard requirement.

Referring to fig. 4-6, in some embodiments, the front windshield assembly 6, the first side panel assembly 3, and the second side panel assembly 4 are each provided with a first through hole a for mounting the windshield 13; the first through holes a are each mounted with a windshield 13 therein.

The size of the first through hole a may be set as large as possible, for example, the size of the first through hole a accounts for more than 80% of the width of the board. By adopting the structure, the cab has wide visual fields at the front side and the left and right sides, thereby effectively increasing the convenience of the operation of a driver and improving the safety of the operation.

The front damper assembly 6 comprises a first plate 61, a second plate 62 and a cross plate 63. The first plate 61 and the second plate 62 are fixedly connected, such as welded. The cross plate 63 is located between the first plate 61 and the second plate 62 and serves as a reinforcement. The first plate 61 is provided with a first through hole a in which the windshield 13 is mounted.

In some embodiments, the first side panel assembly 3 is further provided with a second through hole b in which the windscreen 13 is also mounted. Specifically, the first side plate assembly 3 is located to the right of the front windscreen assembly 6.

Referring to fig. 6, in some embodiments, first side panel assembly 3 includes a first louver 31, a second louver 32, and a bent panel 33. The first window panel 31 is provided with a first through hole a; the second window panel 32 is provided with a second through hole b; the first louver 31 and the second louver 32 are arranged side by side, and the angle between the first louver 31 and the second louver 32 is an obtuse angle. The bent plate 33 is fixed to the bottom of the first and second window plates 31 and 32. The second louver 32 is, for example, diamond-shaped. Wherein, the side of the first window panel 31, the second window panel 32 far away from the bent panel 33 is fixedly connected with the ceiling panel assembly 1, and the side of the bent panel 33 far away from the first window panel 31 is fixedly connected with the bottom panel assembly 2.

Specifically, the included angle between the first louver 31 and the second louver 32 is an obtuse angle, and the first louver 31 is convex, so that the internal space of the cab is increased. The second window panel 32 is also fitted with a windscreen 13 which greatly enlarges the driver's field of view.

The thickness of the second louver 32 is 13.5mm to 14.5mm, specifically, 13.5mm, 14mm, and 14.5mm, for example.

In some embodiments, a guard plate 7 is installed at the outer side of the first through hole a; the protector plate 7 encloses at least the top and sides of the first through-hole a.

In some embodiments, the shield 7 is configured to be C-shaped.

Above-mentioned technical scheme calculates through finite element analysis, combines the overall structure and the load-bearing condition of driver's cabin, confirms the material and the structure of driver's cabin, finds out the weak position of driver's cabin to at weak position set up backplate 7, in order to carry out local reinforcement. The guard plate 7 is only arranged in a local area, so that the high cost caused by reinforcing all the cabs is reduced, and the cab of the large underground scraper can meet the requirements of ROPS and FOPS (Falling-object protective structure, FOPS for short). When the underground scraper rolls over or even rolls, the cab is not damaged, and meanwhile, the cab with the structure can generate certain plastic deformation to absorb impact energy and protect an operator from being injured by impact.

In some embodiments, the second side panel assembly 4 comprises a flat panel 41 and a door panel (not shown), the top profile of the flat panel 41 conforming to the shape of the ceiling panel assembly 1. The door panel is openably and closably mounted on the flat plate 41; the door panel is provided with a first through-hole a for mounting the windshield 13.

Referring to fig. 5, the cab further includes a reinforcing rib plate 9, the reinforcing rib plate 9 is arranged at the joint of the top plate 101 and the second side plate assembly 4, and the reinforcing rib plate 9 is fixedly connected with both the top plate 101 and the second side plate assembly 4. Specifically, the reinforcing rib plate 9 is fixedly connected with the flat plate 41 and the top plate 101. The reinforcing rib plate 9 may be provided in plurality, and a plurality of reinforcing rib plates 9 are arranged in a dispersed manner. The reinforcing rib plate 9 effectively increases the strength of the cab at the joint of the roof panel 101 and the second side panel assembly 4.

When the side loading is found through finite element simulation calculation and a material object test, the deformation of the cab at the front upper arc corner of the second side plate component 4 is large, and therefore a plurality of reinforcing rib plates 9 are welded, so that the deformation of the second side plate component 4 is reduced obviously, and the strength of the second side plate component 4 is increased.

The load-bearing component provides rolling and falling object prevention performance meeting standard requirements for a cab ROPS, and the rolling and falling object prevention performance comprises the following specific steps:

during side direction loading, the cab is twisted and deformed forwards, the corner of the front left windshield 13 is deformed greatly, the flitch 53 is welded on the rear side of the basic framework of the cab, the reinforcing rib plate 9 is welded on the upper portion of the front left side, and the C-shaped guard plate 7 is welded on the periphery of the front left windshield 13.

When vertical load and longitudinal load are loaded, because the closed cab formed by the plates is adopted in the embodiment of the invention, and because of the existence of the reinforcing structure, the deformation of the cab after loading is smaller, and the cab can provide bearing capacity far larger than the standard requirement.

When the heavy hammer falls on the object, because the thickness of the ceiling plate component 1 is thicker, the deformation of the top of the cab is smaller and the cab is not punctured, and the standard requirement of the falling object is far exceeded.

In some embodiments, the cab further includes a first isolator assembly 10, the first isolator assembly 10 being mounted to the bottom exterior side of the floor assembly 2, the first isolator assembly 10 being configured to connect the floor assembly 2 to a frame on which the cab is located.

The first isolator assembly 10 employs, for example, an eccentric damper. Referring to fig. 6 and 10, the first isolator assembly 10 includes an isolator mount 102, a connecting plate 103, a riser 104, an eccentric damper 105, an isolator bolt 106, a first connecting bolt 107, and an isolator cover 108. Wherein the isolator seat 102 is welded on the bottom plate of the cab, and the vertical plate 104 is welded with the connecting plate 103. The eccentric damper 105 is a cylindrical eccentric structure, is wide at the top and narrow at the bottom, and is fixed by the vibration isolator bolt 106. The connecting plate 103 is fixedly connected to the vehicle frame by a first connecting bolt 107, and the isolator cover 108 is bolted to the isolator mount 102 to protect the eccentric damper 105.

When the underground scraper works, the cab can vibrate, and the first vibration isolator assembly 10 connects the cab and the frame, so that vibration is effectively reduced.

In some embodiments, the first isolator assembly 10 comprises a plurality of first isolator assemblies 10 arranged in a distributed manner at the bottom of the baseplate assembly 2.

The number of the first isolator assemblies 10 is three, and the three first isolator assemblies 10 enclose a U-shape. The first vibration isolator assembly 10 is a cylindrical eccentric damper and is thick, and the first vibration isolator assembly 10 bears radial load but does not bear axial load. By arranging the plurality of first isolator assemblies 10 in a predetermined manner, the cab can be subjected to forces in both the lateral and longitudinal directions simultaneously, which makes the stresses more reasonable.

The first vibration isolator assembly 10 effectively reduces vibration between the bottom of the cab and the frame, and simultaneously makes the cab more rigid, thereby facilitating energy absorption, reducing impact, and improving driver comfort and impact absorption capability.

In some embodiments, the cab further includes a second isolator assembly 11, the second isolator assembly 11 being mounted to an edge of the front windshield assembly 6, the second isolator assembly 11 being configured to connect the front windshield assembly 6 to a frame of the cab.

Referring to fig. 4 and 11, the second isolator assembly 11 includes a first mounting plate 111, a first riser 112, a first web 113, a first mounting block 114, a first support damper 115, a first fixing pin 116, and a second connecting bolt 117. The first mounting plate 111, the first riser 112, the first rib 113 and the first mounting block 114 are welded together, and the first support damper 115 is fixed by a first fixing pin 116. First mounting panel 111 passes through second connecting bolt 117 and frame 1 fixed connection, and second isolator subassembly 11 is connected with the driver's cabin skeleton through first support otic placode 118, and first support otic placode 118 welds in the front on support riser 7. Front seat riser 7 is fixed to front windshield assembly 6, which is used to mount second isolator assembly 11.

The second vibration isolator assembly 11 effectively reduces vibration between the cab front windshield assembly 6 and the frame, and simultaneously enables the rigidity of the cab to be better, thereby being beneficial to absorbing energy, reducing impact, and improving the comfort and impact absorbing capability of a driver.

Referring to fig. 6 and 12, in some embodiments, the cab further includes a third isolator assembly 12, the third isolator assembly 12 being mounted to an edge of the first side plate assembly 3, the third isolator assembly 12 being configured to connect the first side plate assembly 3 to a frame on which the cab is located. The third vibration isolator component 12 effectively reduces the vibration between the first side plate component 3 and the frame, and simultaneously makes the rigidity of the cab better, thereby being beneficial to absorbing energy, reducing impact, and improving the comfort of a driver and the impact absorbing capability.

Referring to fig. 4, 5 and 12, the third isolator assembly 12 includes a second mounting plate 121, a second web 122, a second mounting block 123, a second branch damper 124, a second fixing pin 125 and a second connecting bolt 126. The second mounting plate 121, the second rib plate 122 and the first mounting block 114 are welded, and the first support damper 115 is fixed by a second fixing pin 125. The second mounting plate 121 is fixedly attached to the frame by attachment bolts 107, the third isolator assembly 12 is attached to the cab framework by a second mounting ear 127, and the second mounting ear 127 is welded to the first window panel 31.

In the technical scheme, the cab is connected with the frame through the first vibration isolator assembly 10, the second vibration isolator assembly 11 and the third vibration isolator assembly 12. The driver's cabin links firmly with the frame respectively on bottom, front side and the three direction in right side, avoids rocking, makes it more firm, and this structure has greatly improved the intensity of driver's cabin, has improved the ability of absorbed energy when guaranteeing driver's cabin intensity.

The bottom plate is a flat plate 41 or is formed by welding a plurality of plates. The bottom plate itself may be provided with ribs. The thickness of the bottom plate is 18 mm-22 mm, specifically 18mm, 19mm, 20mm, 21mm, 22mm.

The thickness of each plate, the thickness of which is not specifically mentioned above, may be 11.5mm to 12.5mm, specifically, 11.5mm, 12mm, 12.5mm, for example.

The cab with the structure has the advantages that the thickness of each plate is determined jointly according to the bearing capacity, the structure and the structure of the whole cab, the whole weight of the cab is effectively reduced on the premise that the cab meets the safety performance specified by the standard, the light weight of the cab is realized, and the weight of the cab is lightest.

Because the space of the cab of the underground scraper is very small, the cab has the requirements of higher rigidity and strength, small deformation and certain energy absorption capacity, which is a difficult point of the structural design of the cab framework. According to the cab provided by the technical scheme of the embodiment of the invention, the cab framework structure can meet the ROPS and FOPS standard requirements by adopting the technical scheme and matching with some local reinforcement measures. The ROPS can not be damaged under the independent or continuous action of lateral, longitudinal and vertical loads, and simultaneously generates certain plastic deformation, thereby absorbing the impact capacity and reducing the impact injury to operators. The technical scheme is an optimal scheme after finite element optimization, and the cab quality is considered while the safety performance requirement is met.

The embodiment of the invention also provides an underground scraper which comprises the cab provided by any technical scheme of the invention.

The cab is of an integral structure, and can be mounted on a frame after the whole cab is welded. The cab is generally arranged on the fuselage in a side-seated manner, i.e. directly connected to the frame by means of several sets of bolts, as shown in fig. 1.

The underground scraper is mainly used in underground mine and is used to scrape ore or waste rock from working face. The working environment of the underground carry scraper is generally positioned in a narrow and low roadway, and the full-plate cab plate provided by the embodiment of the invention is thicker, so that the scraping during operation can be prevented; and even if the coating is scratched, only the surface of the coating is scratched, so that the coating is not easy to deform.

By the restriction of underground scraper operational environment, its driver's cabin space size is less, and the structure is very compact, and the driver is few and the side is very little with the driver top, rear portion, and the minimum distance of some models is only tens of millimeters (if some model underground scraper driver's cabin rear side is only 30mm apart from people), leads to driver and driver's cabin distance littleer if design for skeleton texture to operation travelling comfort and security performance have been reduced. The cab provided by the embodiment of the invention adopts a full-plate design, the internal space of the cab can reach 1.5 cubic meters, the distance between a driver and each surface of the cab is large, and the safety performance and the comfort are greatly improved. If the upright column framework is adopted, the upright column needs to occupy 0.3-0.5 cubic meter additionally, so that only 1-1.2 cubic meters of used space is left, the distance between a driver and each surface of a cab is very small, and the safety performance and the comfort are greatly reduced.
