Description

Technical Field

[0001] The invention belongs to the field of auxiliary equipment of electric-controlled hydraulic mobile trains for mines, and in particular relates to a deviation-correcting device for electric-controlled hydraulic mobile trains for mines. Background Art

[0002] The electric-controlled hydraulic mobile train set for mining is a transportation equipment in the comprehensive mechanized coal mining system. It is set in the main lane and the auxiliary lane of the coal mining face and is used to carry and transport high-voltage coil cables, high-voltage frequency converters, shifting equipment, combination switch pump boxes, emulsification pumps and various accessories. Due to the frequent deformation, bottom drum, potholes, water accumulation, slope and other conditions of the underground lanes of coal mines, affected by these uncertain factors, the train set does not always move in a straight line during the underground operation, but deviates. In addition, there are main lanes and auxiliary lanes on the coal mining face, and the train set will turn when moving in the lanes.

[0003] When the existing mobile train set needs to adjust or turn, the staff needs to use auxiliary tools to pull the front of the train to offset, so as to complete the correction on the basis of the continuous movement of the entire self-moving train set. Since each train unit of the electric-controlled hydraulic mobile train set is heavy and large in size, it is particularly laborious in the process of adjusting and moving, which reduces the work efficiency of the entire train set; in addition, the ground conditions in the tunnel are complicated. Even if the train set can maintain normal operation as a whole, it is still difficult to ensure the operation of the train unit in the middle of the entire train set. If a train unit in the middle is offset due to an emergency and it is impossible to correct the deviation of the individual train unit, the continued operation of the entire train set will cause equipment damage and wall collision accidents, seriously affecting the operation and production.

[0019] Based on the operation of an electric-controlled hydraulic mobile train set in a complex tunnel, the present invention proposes a deviation-correcting device for an electric-controlled hydraulic mobile train set for mining. The deviation-correcting device is divided into a double-cylinder deviation-correcting device and a single-cylinder deviation-correcting device according to the number of deviation-correcting hydraulic cylinders, and is respectively applicable to a traction car body and a separate intermediate car body of the electric-controlled hydraulic mobile train set. The double-cylinder deviation-correcting device is used to correct the deviation of the traction car body, and further to regulate the overall running direction of the mobile train set; the single-cylinder deviation-correcting device is used to adjust the deviation of a separate intermediate car body, so as to prevent accidents such as damage caused by the deviation of the intermediate car body.

[0020] The technical solution of the present application will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 , Figure 2 as well as Fig. 9 As shown, the mine-use electric-hydraulic mobile train group correction device provided by the present invention is applied to the electric-hydraulic mobile train group 1, which is composed of a number of train units connected end to end and realizes the moving process under the control of the electric control box, wherein each train unit includes a train body 103, and the mine-use electric-hydraulic mobile train group correction device is arranged on the front side of the forward direction of the train body 103 based on the forward direction of the electric-hydraulic mobile train group 1, and is used for correcting the direction of the electric-hydraulic mobile train group 1 when it deviates from the direction during the movement.

[0022] In the present technical solution, the deviation correction device of the electrically-controlled hydraulic mobile train group for mining is divided into a single-cylinder deviation correction device 3 and a double-cylinder deviation correction device 2 according to the different numbers of deviation correction hydraulic cylinders, wherein: the double-cylinder deviation correction device 2 is arranged at the front side of the forward direction of the head end train unit, at this time, the train unit is configured as the traction body 101 of the electrically-controlled hydraulic mobile train group 1, and the remaining train units are configured as the intermediate body 102.

[0023] Specifically: In this technical solution, if Figure 3 As shown, the dual-cylinder correcting device 2 includes a first quick-connect assembly 4 connected to the tractor body 101, a first gravity correcting assembly 5 for providing a correcting action for the dual-cylinder correcting device 2, and a first limiting shell assembly 6 for cooperating and installing the first quick-connect assembly 4 and the first gravity correcting assembly 5.

[0024] like Figure 4-5As shown, the first quick-connect assembly 4 includes a first quick-connect portion 104 integrally arranged with the train body 103 in the traction body 101, and a second quick-connect portion 401 for connecting the train body 103 and the first limiting housing assembly 6, wherein the first quick-connect portion 104 is a rectangular box with an end opening, one end of the second quick-connect portion 401 extends into the first quick-connect portion 104 through the end opening, and the other end of the second quick-connect portion 401 is covered by the first limiting housing assembly 6, so that the second quick-connect portion 401 becomes a connecting mechanism between the train body 103 and the first limiting housing assembly 6, which is used to install the double-cylinder correction device 2 on the front side of the train body 103 in the traction body 101.

[0025] Specifically, the first quick-connect assembly 4 also includes a quick-connect pin 105 that connects the first quick-connect part 104 and the second quick-connect part 401 into one through a through hole. The through hole penetrates the first quick-connect part 104 and the second quick-connect part 401 partially enclosed in the first quick-connect part 104 from top to bottom. Based on this embodiment, the matching method of the first quick-connect part 104 and the second quick-connect part 401, and the setting of the quick-connect pin 105 make the disassembly and assembly process of the dual-cylinder correction device 2 more convenient.

[0026] Pads 106 are provided on both side walls of the second quick-connect part 401 to reduce the installation gap when the second quick-connect part 401 is installed in conjunction with the first quick-connect part 104 . In addition, a lifting hook 10 is provided on the top of the second quick-connect part 401 to lift the dual-cylinder correcting device 2 .

[0027] In addition, in this technical solution, if Figure 4-6 As shown, the first limiting housing assembly 6 includes a first limiting box body with an opening at the bottom, and the first limiting box body is formed by a group of long sides 601 arranged in parallel in the vertical direction, a group of short sides 602 with an angle with the vertical direction, and a first top plate 603. After the long side 601 close to the tractor body 101 is penetrated by the second quick-connection part 401, the end of the second quick-connection part 401 is fixedly connected to the long side 601 away from the tractor body 101. In addition, the angle between each short side 602 and the vertical direction is 20°, and the extension lines of the two short sides 602 intersect.

[0028] As the core of the present invention, Figure 5-7As shown, the first gravity correction component 5 includes a group of first correction hydraulic cylinders 501, and a first rotating shaft 502 which is arranged between a group of long sides 601 and corresponds to the first correction hydraulic cylinders 501 one by one, wherein the cylinder ends of a group of first correction hydraulic cylinders 501 are rotatably arranged in the first limit box through the first rotating shaft 502, and are respectively located on the side close to the short side 602; in addition, the first gravity correction component 5 also includes an abutment plate 503 which is arranged on the short side 602 and is simultaneously located between the first correction hydraulic cylinder 501 and the short side 602. When the cylinder side wall of the first correction hydraulic cylinder 501 is in contact with the abutment plate 503, the angle between the first correction hydraulic cylinder 501 and the vertical direction is also 20°. The specific structure is as shown in FIG. Figure 7 As shown, on this basis, the bottom end of the abutting plate 503 is aligned with the bottom end of the short side portion 602 , and in the vertical section, the height of the abutting plate 503 is one third of the height of the short side portion 602 .

[0029] Based on the above structure, when the traction body 101 deviates to one side during operation and needs to be corrected by the mining electric-controlled hydraulic mobile train group correction device provided by the present invention, the double-cylinder correction device 2 is first installed on the front side of the train body 103 in the traction body 101 through the first quick-connect assembly 4, and then the first correction hydraulic cylinder 501 on the same side as the target correction direction is controlled to start working, that is: the piston end of the first correction hydraulic cylinder 501 starts to extend in a direction with an angle of 20° to the vertical direction until it abuts against the ground, and then the first correction hydraulic cylinder 501 continues to work, and on the basis of the abutment between the ground and the piston end of the first correction hydraulic cylinder 501, the movement of the first correction hydraulic cylinder 501 is converted into the movement of the cylinder body lifting, thereby pushing the front side of the train body 103 in the traction body 101 away from the bottom surface.

[0030] Since the running direction of the first correcting hydraulic cylinder 501 is at an angle of 20° to the vertical direction, the front end of the tractor body 101 is lifted up obliquely, and the tractor body 101 falls back to the ground in the target offset direction due to its own weight. At this time, the first correcting hydraulic cylinder 501 rotates around the first rotating shaft 502 and the first correcting hydraulic cylinder 501 is still in an extended state as a whole, but the tractor body 101 has been re-attached to the ground, and the overall extension direction of the first correcting hydraulic cylinder 501 is at an angle greater than 20° to the vertical direction, and the cylinder body of the first correcting hydraulic cylinder 501 is separated from the abutment plate 503, achieving the following Figure 8 The state shown; then the piston end of the first correcting hydraulic cylinder 501 is retracted to the initial state, the cylinder body of the first correcting hydraulic cylinder 501 is again fitted with the abutment plate 503, and the entire double-cylinder correcting device 2 returns to the initial working state, completing a correction process of the double-cylinder correcting device 2. If it is found that the tractor body 101 is still in an offset state, continue to repeat the above steps until the offset of the tractor body 101 is gradually corrected.

[0031] It should be noted that in the above embodiment: First, the angle between the first correcting hydraulic cylinder 501 and the vertical direction is 20°, and the limit of the angle represents the optimal situation. If the angle is too large, the first correcting hydraulic cylinder 501 cannot lift the front side of the tractor body 101 within the entire extension stroke, and thus cannot complete the correcting process; if the angle is too small, the single correcting distance of the first correcting hydraulic cylinder 501 is short, thereby reducing work efficiency.

[0032] Second, due to the existence of the abutment plate 503, there is a gap between the cylinder body of the first deviation-correcting hydraulic cylinder 501 and the short side portion 602, and the width of the gap is the thickness of the abutment plate 503; and because the bottom end of the abutment plate 503 is aligned with the bottom end of the short side portion 602, and the height is one-third of the height of the short side portion 602, when the first deviation-correcting hydraulic cylinder 501 rotates around the first rotating shaft 502, it avoids interference with the short side portion 602. The specific structural relationship between the abutment plate 503, the short side portion 602, and the first deviation-correcting hydraulic cylinder 501 is as follows: Figure 7-8 shown.

[0033] Based on the one-time correction process of the double-cylinder correction device 2, considering the smoothness and safety of the first correction hydraulic cylinder 501 during the rotation process, as shown in FIG. Figure 6 As shown, the present invention further provides a group of first clearance grooves 402 on the left and right side walls of the second quick-connecting portion 401, and the group of first clearance grooves 402 are simultaneously located inside the first limiting housing assembly 6, for preventing each first deviation-correcting hydraulic cylinder 501 from interfering with the second quick-connecting portion 401 when rotating through the first rotating shaft 502; in addition, the present invention further provides a first support plate 504 rotatably connected to the piston end of each first deviation-correcting hydraulic cylinder 501 through a first hinge, and the rotation direction of the first support plate 504 is the same as that of the first deviation-correcting hydraulic cylinder 501. On this basis, an anti-slip portion 11 is provided at the bottom of the first support plate 504 to prevent sliding during the process of lifting the front side of the tractor body 101.

[0034] In this technical solution, if Figure 5-6 As shown, for the convenience of control, the present invention also connects the control of the dual-cylinder correcting device 2 to the overall control system of the electric-controlled hydraulic mobile train group 1, and for the sake of structural beauty, the electric control box is installed on the first top plate 603, and a number of through holes 604 are also opened on the first top plate 603 for the oil pipe of the first correcting hydraulic cylinder 501 and the control line of the electric control box to pass through. In addition, a number of ribs 605 are also provided between the first top plate 603 and the long side 601 to increase the supporting strength of the first top plate 603.

[0035] In another embodiment, the present invention provides a single cylinder correction device 3 for the correction process of the intermediate vehicle body 102, such as Fig. 9As shown, the single-cylinder correcting device 3 includes a second quick-connect assembly 7 connected to the intermediate vehicle body 102, a second gravity correcting assembly 8 for providing a correcting action for the single-cylinder correcting device 3, and a second limiting shell assembly 9 for cooperating in installing the second quick-connect assembly 7 and the second gravity correcting assembly 8.

[0036] like Figure 4 , Figure 9-11 As shown, the second quick-connect assembly 7 includes a first quick-connect portion 104 integrally arranged with the train body 103 in the intermediate car body 102, and a third quick-connect portion 701 for connecting the train body 103 and the second limiting shell assembly 9, wherein the structure of the first quick-connect portion 104 on the train body 103 in any train unit is the same, so one end of the third quick-connect portion 701 also extends into the first quick-connect portion 104 through the end opening, and the other end of the third quick-connect portion 701 is fixedly connected to the second limiting shell assembly 9, so that the third quick-connect portion 701 becomes a connecting mechanism between the train body 103 and the second limiting shell assembly 9, which is used to install the single-cylinder correction device 3 on the front side of the train body 103 in the intermediate car body 102.

[0037] Specifically, the second quick-connect assembly 7 also includes a quick-connect pin 105 that connects the first quick-connect part 104 and the third quick-connect part 701 into one through a through hole. The through hole penetrates the first quick-connect part 104 and the third quick-connect part 701 partially covered by the first quick-connect part 104 from top to bottom. Based on this embodiment, the matching method of the first quick-connect part 104 and the third quick-connect part 701, and the setting of the quick-connect pin 105 make the disassembly and assembly process of the single-cylinder correction device 3 more convenient.

[0038] Pads 106 are also provided on both side walls of the third quick-connect portion 701 to reduce the installation gap when the third quick-connect portion 701 is matched with the first quick-connect portion 104 for installation.

[0039] In addition, in this technical solution, if Figure 10-11 As shown, the second limiting housing assembly 9 includes a second limiting box body with an opening at the bottom, and the second limiting box body is formed by a group of correspondingly arranged mounting plates 901 , a group of correspondingly arranged side plates 902 , and a second top plate 903 .

[0040] Among them, the second top plate 903 is fixedly connected to the end of the third quick-connecting part 701, and the outer wall of a mounting plate 901 is fixedly connected to the front side wall of the third quick-connecting part 701. In addition, a group of correspondingly arranged side plates 902 are fixedly connected to the left and right side walls of the third quick-connecting part 701 while enclosing the mounting plate 901 and the second top plate 903 to form a second limiting box body. Such a setting increases the connection strength between the second limiting shell assembly 9 and the third quick-connecting part 701; on this basis, two groups of limiting holes 904 are correspondingly provided on a group of mounting plates 901, each group of limiting holes 904 are rectangular long holes, and each group of limiting holes 904 has an angle of 20° with the vertical direction. At the same time, the extension lines of the two groups of limiting holes 904 intersect.

[0041] The invention core is the same as above. Figure 10-11 As shown, the second gravity correcting component 8 includes a second correcting hydraulic cylinder 801 and a second rotating shaft 802 arranged between a group of mounting plates 901, wherein the cylinder end of the second correcting hydraulic cylinder 801 is rotatably arranged in the second limit box through the second rotating shaft 802; in addition, the second gravity correcting component 8 also includes a limit plate 803 matched with the limit hole 904, when the limit plate 803 is matched with any group of limit holes 904, the cylinder side wall of the second correcting hydraulic cylinder 801 is in contact with the limit plate 803, and at this time, the angle between the second correcting hydraulic cylinder 801 and the vertical direction is also 20°.

[0042] In this embodiment, when the abutting effect of the limiting plate 803 and the limiting hole 904 on the second correcting hydraulic cylinder 801 in the coordinated state is equivalent to the abutting effect of the abutting plate 503 and the short side 602 on the first correcting hydraulic cylinder 501 in the coordinated state, the specific correction process of the single-cylinder correcting device 3 is the same as the correction process of the double-cylinder correcting device 2 in the above-mentioned embodiment, and the correction process in different directions in the single-cylinder correcting device 3 is reflected in the different angular directions of the two groups of limiting holes 904. When the abutting plate 503 is matched with different limiting holes 904, it is only necessary to manually push the second correcting hydraulic cylinder 801 to rotate it, and then match the abutting plate 503 with the required limiting hole 904.

[0043] Based on the above embodiment, considering the smoothness and safety of the second deviation-correcting hydraulic cylinder 801 during the rotation process, as shown in FIG. Fig.11As shown, the present invention also has a second clearance groove 905 on each side plate 902, which is used to prevent the second correcting hydraulic cylinder 801 from interfering with the second limiting box when rotating through the second rotating shaft 802; on this basis, a lifting hook 10 is provided on each side plate 902, which is used for lifting the single-cylinder correcting device 3 as a whole; in addition, the present invention also has a second support plate 804 rotatably connected to the piston end of the second correcting hydraulic cylinder 801 through a second hinge, and the rotation direction of the second support plate 804 is the same as the rotation direction of the second correcting hydraulic cylinder 801, and an anti-skid portion 11 is provided at the bottom of the second support plate 804 to prevent sliding during the lifting process of the front side of the intermediate car body 102; in addition, in the second limiting shell assembly 9, a mounting ring 906 is also provided on the mounting plate 901, and a connecting rope is provided in the mounting ring 906, and the end of the connecting rope is connected to the limiting plate 803 to prevent the limiting plate 803 from being lost when the single-cylinder correcting device 3 is not in use.

[0044] As another core of the present invention, in the mine-use electric-controlled hydraulic mobile train group correcting device provided by the present invention, the size and model of the first correcting hydraulic cylinder 501 and the second correcting hydraulic cylinder 801 are exactly the same, and the maximum stroke is 200mm, the maximum pressure is not less than 31.5MPa, and the maximum correction distance is 100mm. On this basis, except for the first correcting hydraulic cylinder 501 and the second correcting hydraulic cylinder 801, the materials of the remaining components are all Q460, and the size of the single-cylinder correcting device 3 is smaller than the double-cylinder correcting device 2 as a whole, so there are differences in the lifting costs of different mine-use electric-controlled hydraulic mobile train group correcting devices.

[0045] Since the traction body 101 of the mining electric-controlled hydraulic mobile train set deflects and turns more frequently during normal use than the intermediate body 102 due to accidents, a double-cylinder correction device 2 is provided on the traction body 101, and the control system is connected to the overall control of the electric-controlled hydraulic mobile train set 1 to prepare for multiple corrections; a single-cylinder correction device 3 is provided on the intermediate body 102, but not every intermediate body 102 is equipped with a single-cylinder correction device 3. When a certain intermediate body 102 deflects, the single-cylinder correction device 3 can be quickly installed on the intermediate body 102 to be corrected through the second quick-connect assembly 7. After the correction process of the intermediate body 102 is completed, it can be disassembled and assembled on another intermediate body 102 again. There is no need to install a correction device for the mining electric-controlled hydraulic mobile train set on each train unit, which saves production costs to a great extent.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
