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 technique

Underground scrapers generally work in mines, and the working conditions in mines are very harsh, and sometimes pumice will fall from the top. The slope of the underground mine is steep, there are many bends, and the road is uneven. If you are not careful, you may overturn. At the same time, the safety performance requirements for underground LHDs in the industry are gradually increasing, and the cab needs to meet the performance requirements of anti-rollover and anti-falling objects. Anti-rollover means that in the case of rollover, the cab does not roll over or only rolls over at a small angle. Falling object prevention means that when a falling object falls on the cab, the falling object will not fall through the cab. Therefore, the industry urgently needs to design an underground scraper that can meet the performance requirements of anti-rollover and anti-falling objects.

However, the inventors have found that since the operating environment of the underground loader is a narrow tunnel, the width and height of the fuselage of the underground loader are strictly limited, which makes the cab space very small and difficult It is made into a closed structure like a large scraper on the ground. At the same time, the safety and comfort of driving directly affect the driver's misoperation and work efficiency, which makes it difficult to design a cab that meets the requirements under limited space constraints.

In related technologies, in order to meet the performance requirements of anti-rolling and anti-falling objects, the cab of the underground scraper is welded with section steel as the skeleton, and thick steel plates are welded externally; or the cab of the underground scraper is made into a semi-closed structure, To meet the requirements of large field of view.

The inventors have found that the prior art has at least the following problems: Since the body width and height of the underground scraper are strictly limited, the cab space is very small, and the size requirements are strict. The room frame will make its space smaller, which seriously affects the comfort of the driver, thereby reducing work efficiency and increasing the probability of misoperation; and the semi-closed structure cannot meet the performance requirements of falling objects.

The technical solution provided by the present invention will be described in more detail below in conjunction with FIGS. 1 to 12 .

In this paper, the orientations of top, bottom, front, back, left, and right are defined by the direction of the driver's operation.

An embodiment of the present invention provides a cab, including a ceiling panel assembly 1 , a floor panel assembly 2 , a first side panel assembly 3 , a second side panel assembly 4 , a back panel assembly 5 and a front windshield assembly 6 . The ceiling panel assembly 1 is located on the top of the cab; the bottom panel assembly 2 is spaced apart from the ceiling panel assembly 1 and is located at the bottom of the cab; the first side panel assembly 3 is arranged between the ceiling panel assembly 1 and the bottom panel assembly 2; the second side The panel assembly 4 is arranged at a distance from the first side panel assembly 3, and is also arranged between the ceiling panel assembly 1 and the floor assembly 2; the back panel assembly 5 is also arranged between the ceiling panel assembly 1 and the floor assembly 2; the front windshield The assembly 6 is also arranged between the ceiling panel assembly 1 and the floor assembly 2 ; Wherein, the roof panel assembly 1 , the bottom panel assembly 2 , the side panel assembly, the back panel assembly 5 and the front windshield assembly 6 together form a closed space.

The cab provided by the embodiment of the present invention is a closed structure, so the performance of preventing falling objects is good. In the case of falling objects, the falling objects cannot enter the interior of the closed cab, which effectively improves the safety of the cab; And the driver's cab does not need to be separately equipped with a frame formed by welded section steel, so the space inside the driver's cab is large, so that the driver has enough operating space, which greatly improves the driver's comfort, thereby improving work efficiency and reducing misoperation. probability.

Referring to FIG. 1 , in some embodiments, the cab is configured with a top cross-sectional dimension that is greater than a bottom cross-sectional dimension. Seen from the front view direction, the upper part of the cab is wider and the lower part is narrower. On the premise of increasing the space in the cab, this design takes into account the structural stability and impact resistance of the cab, so that it has good anti-rolling and anti-falling performance. The requirements for anti-rolling and anti-falling are as follows: the cab has sufficient strength and rigidity to ensure that it will not be damaged or deformed too much under continuous lateral, longitudinal and vertical loads, so as to protect the vehicle driver from intrusion damage ; And it must have a certain deformation and energy absorption capacity to reduce the impact on the driver.

The specific structure of each part of the cab is introduced in detail below.

The ceiling panel assembly 1 is the top part of the cab, and the ceiling panel assembly 1 plays a role in preventing falling objects from entering the cab. The ceiling panel assembly 1 covers the tops of the first side panel assembly 3 , the second side panel assembly 4 , the front windshield assembly 6 , and the back panel assembly 5 . The first side panel assembly 3 , the second side panel assembly 4 , the front windshield assembly 6 , and the back panel assembly 5 together form a shape with both top and bottom openings. The size of the ceiling panel assembly 1 is larger than the top of the opening, so that the protective area of the ceiling panel is larger.

Referring to FIGS. 1 to 4 , 7 and 8 , especially FIGS. 7 and 8 , in some embodiments, the ceiling panel assembly 1 includes a top panel 101 configured to be bent. The top board 101 can be formed by bending a whole board. The size of the top plate 101 is greater than the size of the top of the opening surrounded by the first side plate assembly 3, the front windshield assembly 6, the second side plate assembly 4, and the back plate assembly 5, and the top plate 101 covers the top of the opening; the top plate 101 is located on the back plate The edge of the side where the component 5 is located is inclined downward toward the back plate and bent, so that falling objects slide down from the inclination of the top plate 101 .

In some embodiments, the ceiling panel assembly 1 has a thickness of 13.5mm˜14.5mm, specifically 13.5mm, 14mm, and 14.5mm. After finite element analysis and calculation, this parameter can provide the required rigidity and lightweight requirements of the cab to the maximum extent.

Referring to FIG. 7 and FIG. 8 , the backplane assembly 5 includes a first baffle 51 and a second baffle 52 . The first baffle 51 and the second baffle 52 extend downward along the bottom edge of the top board 101 . The first baffle 51 and the top plate 101 are integrated, and the angle α between the first baffle 51 and the top plate 101 is 128°˜130°. The second baffle 52 and the first baffle 51 are also integrated, and the angle β between the second baffle 52 and the first baffle 51 is 167°˜170°.

The first baffle plate 51 and the second baffle plate 52 of the ceiling panel assembly 1 and the back panel assembly 5 are integrally bent and formed, and are bent twice to obtain a desired shape. The included angle α is 128°-130°, and the included angle β is 167°-170°. After finite element analysis and calculation, the bending structure and bending angle are the optimal structure type, which can provide the required rigidity and energy absorption capacity of the cab to the maximum extent.

Referring to FIG. 9 , the backplane assembly 5 further includes a sticking plate 53 , and the sticking plate 53 is bonded to the first baffle 51 and the second baffle 52 and fixed by welding. The first baffle plate 51 , the second baffle plate 52 and the pasting plate 53 are welded and fixed, and face to face.

The pasting plate 53 is a bent thin plate, and its thickness is, for example, 7.5 mm to 8.5 mm, specifically, 7.5 mm, 8 mm, or 8.5 mm. The lower left side and the upper right side are subjected to edge bending treatment to facilitate the firm welding of the panel 53 and the driver's cab, so as to strengthen the strength and impact resistance of the first baffle plate 51 and the second baffle plate 52 . After the finite element topology optimization of the rear plate 53, the upper left side and the lower right side of the parts that contribute little to the strength are removed. The plate 53 is provided with inner grooves in the middle of its own height direction and on the top side. Through the inner grooves Reduce the weight of the panel 53, achieve the purpose of weight reduction without reducing the strength of the panel 53 itself, and effectively reduce the weight of the whole vehicle while ensuring the rigidity of the cab.

In some embodiments, the thickness of the ceiling board assembly 1 is also the thickness of the roof 101, the first baffle 51, and the second baffle 52, that is, the thicknesses of the first baffle 51 and the second baffle 52 are also 13.5mm-14.5mm, Specific examples are 13.5mm, 14mm, and 14.5mm. The ceiling panel assembly 1 with the above thickness has a strong bearing capacity, and the thickness of the ceiling panel assembly 1 matches its structural shape, which can meet the safety performance specified in the standard for the load-carrying cab and is the lightest solution at the same time. After the test of falling objects with a heavy hammer, since the roof panel assembly 1 adopts the above-mentioned structure and parameters, after the heavy hammer falls, the deformation of the top of the cab is small, and the heavy hammer does not penetrate the roof panel assembly 1 of the cab. The performance of component 1 far exceeds the requirements of the falling objects standard.

4 to 6, in some embodiments, the front windshield assembly 6, the first side panel assembly 3 and the second side panel assembly 4 are all provided with a first through hole a for installing the windshield 13; A windshield 13 is installed in each through hole a.

The size of the first through hole a can 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 on which it is located. With the above-mentioned structure, the driver's cab has a wide field of vision on the front side, left and right sides, which effectively increases the convenience of the driver's operation and improves the safety of the operation.

The front fairing assembly 6 includes a first panel 61 , a second panel 62 and a transverse panel 63 . The first plate 61 and the second plate 62 are fixedly connected, such as welding. The horizontal plate 63 is located between the first plate 61 and the second plate 62 to play a reinforcing role. The first plate 61 is provided with a first through hole a in which the windshield 13 is installed.

In some embodiments, the first side panel assembly 3 is further provided with a second through hole b, and the windshield 13 is also installed in the second through hole b. Specifically, the first side panel assembly 3 is located on the right side of the front windshield assembly 6 .

Referring to FIG. 6 , in some embodiments, the first side panel assembly 3 includes a first window panel 31 , a second window panel 32 and a bent panel 33 .

The bent plate 33 is fixed on the bottom of the first window plate 31 and the second window plate 32 . The second window panel 32 is, for example, diamond-shaped. Wherein, the sides of the first window panel 31 and the second window panel 32 away from the bent plate 33 are both fixedly connected to the ceiling panel assembly 1 , and the side of the bent panel 33 away from the first window panel 31 is fixedly connected to the bottom panel assembly 2 .

Specifically, the included angle between the first window panel 31 and the second window panel 32 is an obtuse angle, and the first window panel 31 protrudes forward, which increases the interior space of the cab. The second window panel 32 is also equipped with a windshield 13, which greatly expands the driver's field of vision.

The thickness of the second window plate 32 is 13.5mm˜14.5mm, specifically 13.5mm, 14mm, 14.5mm.

In some embodiments, a guard plate 7 is installed on the outside of the first through hole a; the guard plate 7 at least surrounds the top and sides of the first through hole a.

In some embodiments, the guard plate 7 is configured C-shaped.

In the above technical solution, through finite element analysis and calculation, combined with the overall structure and bearing conditions of the cab, determine the material and structure of the cab, find out the weak parts of the cab, and set the guard plate 7 at the weak parts for local reinforcement . Since the guard plate 7 is only set in a local area, the high cost of strengthening all cabs is reduced, so that the cab of a large underground loader can also meet the requirements of ROPS and FOPS (Falling-object protective structure) , referred to as FOPS) requirements. When the underground scraper is overturned or even rolled over, the cab will not be damaged. At the same time, the cab with this structure will produce a certain plastic deformation to absorb the impact energy and protect the operator from impact damage.

In some embodiments, the second side panel assembly 4 includes a flat panel 41 and a door panel (not shown in the figure), and the top profile of the flat panel 41 conforms to the shape of the ceiling panel assembly 1 . The door panel is openably and closably installed on the flat plate 41 ; the door panel is provided with a first through hole a for installing the windshield glass 13 .

Referring to FIG. 5 , the driver's cab also includes a rib plate 9 , which is arranged at the junction of the top plate 101 and the second side plate assembly 4 , and the rib plate 9 is fixedly connected with the top plate 101 and the second side plate assembly 4 . Specifically, the rib plate 9 is fixedly connected to the flat plate 41 and the top plate 101 . A plurality of stiffener plates 9 can be provided, and a plurality of stiffener plates 9 are scattered and arranged. The stiffener plate 9 effectively increases the strength of the cab at the joint between the top plate 101 and the second side plate assembly 4 .

Through the finite element simulation calculation and physical test, it is found that when the side load is applied, the cab deforms greatly at the front upper arc corner of the second side panel assembly 4, so a plurality of rib plates 9 are welded to reduce the second side panel The deformation of the component 4 is obvious, which increases the strength of the second side plate component 4 .

The load-bearing components provide cab ROPS with anti-rollover and anti-falling object performance that meets the standard requirements, as follows:

When laterally loaded, the cab twists and tilts forward, and the corner of the windshield 13 on the left front is deformed greatly. There is a plate 53 welded on the rear side of the basic skeleton of the cab, and a stiffener plate 9 is welded on the upper part of the left front side. A C-shaped guard plate 7 is welded around the windshield 13. These reinforced structures make the force of the entire ROPS more reasonable, the deformation is small, and can provide sufficient bearing capacity and energy absorption.

When loading vertical load and longitudinal load, since the embodiment of the present invention adopts a closed cab composed of various panels, and due to the existence of the reinforcement structure, the deformation of the cab after loading is small, and the cab can provide much larger than the standard requirements. carrying capacity.

When heavy hammer falls, due to the thick ceiling plate assembly 1, the top of the cab has little deformation and no breakdown, which far exceeds the requirements of the falling object standard.

The driver's cab provided by the technical solution of the embodiment of the present invention adopts the above-mentioned technical solution and cooperates with some partial strengthening measures, so that the skeleton structure of the driver's cab can meet the requirements of ROPS and FOPS standards. ROPS will not be damaged under the single or continuous action of lateral, longitudinal and vertical loads, and at the same time, it will produce certain plastic deformation to absorb impact and reduce the impact injury suffered by the operator. This technical solution is the optimal solution after finite element optimization, which takes into account the quality of the cab while meeting the safety performance requirements.

An embodiment of the present invention also provides an underground scraper, including the cab provided by any technical solution of the present invention.

The cab described above is an integral structure, which can be installed on the frame after the cab is welded as a whole. The cab is generally arranged on the fuselage in a side-sitting style, that is, it is directly connected to the frame through several sets of bolts, as shown in Figure 1.

The working conditions of underground scrapers are mainly underground mines, which are used to scrape ore or waste rocks on the working face. The working environment of the underground scraper is generally located in a narrow and low roadway. The full-slab cab plate provided by the embodiment of the present invention is thicker, which can prevent scratches during operation; and even if it is scratched, only scratches appear on the surface. Not easily deformed.

Due to the limitation of the working environment of the underground scraper, the space size of the cab is small and the structure is very compact. The distance between the driver and the top, rear and side of the cab is very small, and the minimum distance of some models is only tens of millimeters (such as some The distance between the rear side of the cab of the type underground scraper is only 30mm), if it is designed as a skeleton structure, the distance between the driver and the cab will be smaller, thereby reducing the operating comfort and safety performance. The cab provided by the embodiment of the present invention adopts a full-plate design, and the interior space of the cab can reach 1.5 cubic meters. The distance between the driver and each side of the cab is large, which greatly improves the safety performance and comfort. If the column framework is used, the column needs to occupy an additional 0.3 to 0.5 cubic meters, so the usable space is only 1 to 1.2 cubic meters, and the distance between the driver and the cab is very small, which greatly reduces the safety performance and comfort.
