Description

Technical Field

[0002] As an auxiliary transportation equipment in coal mines, monorail crane locomotives have the advantages of strong safety, strong driving force, strong adaptability, small space occupation and high transportation efficiency. They are widely used in narrow spaces such as tunnels and mines. They are auxiliary transportation equipment suitable for most coal mines in my country. Monorail crane locomotives are powered by explosion-proof diesel engines or batteries. The locomotive can move along the track suspended above the tunnel or mine. The entire monorail crane transportation line is formed by connecting multiple fixed-length tracks. Connecting parts are welded at both ends of the track. Through the connecting parts, the two adjacent tracks can be connected together, and then the connected tracks are fixed in a unique way at the designated position of the mine tunnel through the hanging parts, thereby forming a designated transportation route. After the track is installed, the monorail crane locomotive can transport materials along the track.

[0003] The common existing track is 2.4 meters per track. After field use and test analysis, the maximum load-bearing weight is ≤60 tons. Most of the existing demand conditions can meet this requirement. However, with the development of mine auxiliary transportation technology and the emergence of ultra-high mining height mines, ultra-heavy hydraulic supports have also appeared.

[0055] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0056] It should be noted that the directional words such as "upper" and "lower" mentioned below are defined based on the drawings in the specification.

[0057] The core of the utility model is to provide an ultra-heavy rail hanging device, which welds two existing heavy rails with the same structural dimensions together to form a frame structure, and enhances the torsional strength of the rail by setting a reinforcing plate 2 to prevent the rail from being welded open, so as to meet the transportation work of the ultra-heavy hydraulic support and save costs.

[0058] Please refer to Figure 1 and Figure 2 An ultra-heavy track hanging device includes an ultra-heavy track 1, a reinforcement plate 2, a track connecting structure 3, a hanging structure 4 and a tensioning structure 5.

[0059] Specifically, the super-heavy track 1 includes two heavy-duty tracks welded in parallel to increase the transport weight that the super-heavy track 1 can bear, so as to meet the transport work of the super-heavy hydraulic support. The reinforcing plate 2 is arranged on the super-heavy track 1, and a plurality of reinforcing plates 2 are arranged. The plurality of reinforcing plates 2 are arranged along the length direction of the super-heavy track 1. The reinforcing plates 2 are welded to the top and bottom of the super-heavy track 1 to enhance the torsional strength of the super-heavy track 1 and prevent the super-heavy track 1 from being welded open, so as to ensure the transport work of the super-heavy hydraulic support. The track connection structure 3 is arranged at the ends where two adjacent super-heavy tracks 1 are connected, and is used to connect the two adjacent super-heavy tracks 1 so that the super-heavy tracks 1 can be connected. The connection is stable enough, one end of the hanging structure 4 is connected to the track connecting structure 3, and the other end of the hanging structure 4 is connected to the top plate. The connection between the top plate and the super-heavy track 1 is realized through the hanging structure 4, so that the super-heavy track 1 is in a horizontal state, providing a channel for the transportation of the super-heavy hydraulic support, one end of the tensioning structure 5 is connected to the track connecting structure 3, and the other end of the tensioning structure 5 is connected to the top plate, and the tensioning structure 5 is tensioned between the track connecting structure 3 and the top plate to stabilize the position of the super-heavy track 1 and avoid violent swinging of the super-heavy hydraulic support during transportation on the super-heavy track 1, so that the super-heavy hydraulic support can be smoothly transported on the super-heavy track 1.

[0060] Among them, in terms of processing technology, after the heavy-duty rails are spliced, their wing plate positions can be used as welding positions. The upper and lower wing plates of the heavy-duty rails can be welded. Segment welding is adopted to prevent welding deformation. The welds are straight-line welded, which is convenient for welding with intelligent welding equipment, thereby improving welding strength and production efficiency.

[0061] The super-heavy rail hanging device is arranged in the above manner, and the super-heavy rail 1 is two existing heavy rails of the same size welded together side by side to enhance the torsional strength of the super-heavy rail 1, making it suitable for the transportation of super-heavy materials. Reinforcing plates 2 are welded at appropriate positions of the upper and lower wing plates of the super-heavy rail 1 to prevent open welding and increase the torsional strength of the super-heavy rail 1.

[0062] Please refer to Figure 3 The reinforcing plate 2 is rectangular and is provided with a trapezoidal snap-in groove 21 that matches the super-heavy track 1. An opening 22 is provided inside the reinforcing plate 2. The reinforcing plate 2 is welded to the super-heavy track 1 through the opening 22 and the trapezoidal snap-in groove 21.

[0063] It should be noted that the use of reinforcing plates 2, based on the welding of two heavy-duty rail splicing sections, and adding reinforcing plates 2 at appropriate positions can not only increase the torsional resistance of the super-heavy rail 1, but also prevent the welding positions of the super-heavy rail 1 from being cracked.

[0064] Among them, the reinforcing plate 2 adopts a rectangular internal opening 22 structure, which can be formed by forging or processing, and adopts an internal and external full-circle welding method to increase the welding strength. It adopts a trapezoidal closed structure. On the basis of not processing the wing plate of the super-heavy track 1, it can bypass the wing plate of the super-heavy track 1 and can be welded with the wing plate into an integrated structure.

[0065] Please refer to Figure 4 The track connection structure 3 includes a first connection structure and a second connection structure. The first connection structure is arranged at the top of the super-heavy track 1, and the second connection structure is arranged at the bottom of the super-heavy track 1. The first connection structure and the second connection structure are both used to connect the super-heavy track 1.

[0066] It can be understood that the route of the monorail crane auxiliary transportation system is connected by multiple super-heavy rails 1 of fixed length. Reliable and stable connection between the super-heavy rails 1 is an important guarantee for realizing efficient and safe transportation of the monorail crane. The super-heavy rails 1 are connected by a rail connection structure 3.

[0067] Among them, in this embodiment, the first connecting structure is arranged at the top of the super-heavy track 1, and the second connecting structure is arranged at the bottom of the super-heavy track 1, but in actual life, there is no limitation to this, as long as the above-mentioned technical effect can be achieved.

[0068] Please refer to Figure 5 and Figure 6 The first connecting structure includes a T-shaped arc seat 31 and a double-ear arc connecting seat 32. The T-shaped arc seat 31 is welded to the top of the super-heavy rail 1. The bottom of the T-shaped arc seat 31 is provided with a trapezoidal welding groove 311 that matches the super-heavy rail 1, and the top is provided with an arc-shaped crimping flange 312. The T-shaped arc seat 31 is provided with reinforcing ribs, waist-shaped circular holes 313 and circular mounting holes 314. The mounting hole 314 is used to connect the tensioning structure 5. The double-ear arc connecting seat 32 includes two arc seats. The top of the arc seat is provided with an arc pressure-bearing surface 321 that matches the crimping flange 312. The arc seat is provided with a circular hole 322 that matches the waist-shaped circular hole 313. The bottom of the arc seat is welded to the top of the super-heavy rail 1.

[0069] It should be noted that structures for matching and connecting adjacent super-heavy rails 1 are welded at both ends of the super-heavy rail 1, one end is welded with a double-ear arc connecting seat 32, and the other end is welded with a T-shaped arc seat 31. The double-ear arc connecting seat 32 is composed of two symmetrical arc seats and is a split structure. It is welded on the upper plane of the super-heavy rail 1, and can also enhance the torsion resistance of the super-heavy rail 1. The T-shaped arc seat 31 is an integrated T-shaped arc structure, which is welded on the upper plane of the super-heavy rail 1 through a trapezoidal welding groove 311. When two adjacent super-heavy rails 1 are connected, the double-ear arc connecting seat 32 cooperates with the T-shaped arc seat 31, and the T-shaped arc seat 31 is inserted into the double-ear arc connecting seat 32. The crimping flange 312 of the T-shaped arc seat 31 is just crimped on the arc pressure-bearing surface 321 of the double-ear arc connecting seat 32, and the fixing bolts are inserted into the waist-shaped circular holes 313 and the circular holes 322, and fastened with fixing nuts.

[0070] Furthermore, reinforcing ribs are provided on the T-shaped arc seat 31 to increase the torsional strength of the T-shaped arc seat 31 and prevent the super-heavy track 1 from twisting and deforming during operation. There is a waist-shaped circular hole 313 in the middle of the T-shaped arc seat 31. Because the two super-heavy tracks 1 are allowed to rotate at a certain angle when the super-heavy track 1 is installed and used, the waist-shaped circular hole 313 is used. Under the premise of ensuring the insertion of the connecting pin shaft, the super-heavy track 1 can still rotate and have a certain amount of activity, which prevents the super-heavy track 1 from being rigidly connected and causing extrusion damage. The T-shaped arc seat 31 has a mounting hole 314. According to the use of the super-heavy track 1, a tensioning structure 5 is provided to fix the chain to prevent the super-heavy track 1 from lateral swinging and twisting. The tensioning structure 5 is connected to the super-heavy track 1 through the mounting hole 314.

[0071] Among them, the T-shaped arc seat 31 and the double-ear arc connecting seat 32 have arc joint surfaces that cooperate with each other to bear the hanging force. In actual life, there is no restriction on the size and position of the arc, as long as the above-mentioned technical effect can be achieved.

[0072] On the basis of the above embodiment, a gap of 2-3 mm is left between the T-shaped arc seat 31 and the double-ear arc connecting seat 32 .

[0073] It can be understood that when the T-shaped arc seat 31 is inserted into the double-ear arc connecting seat 32, the single-side gap is about 2-3mm. This margin mainly has the following functions. First, it is easy to adjust during installation and convenient to install. Second, when the locomotive is running, the two matching super-heavy rails 1 at the joint of the super-heavy rails 1 have a certain amount of activity space, and the super-heavy rails 1 will not swing too much to the left and right, and will not show "S"-shaped distortion, which will not affect the locomotive operation efficiency.

[0074] Among them, the arc length of the joint surface between the T-shaped arc seat 31 and the double-ear arc connecting seat 32 is about 150mm, and the two sides are symmetrically crimped, which can reduce the friction at the positions of the fixing bolts, the waist-shaped circular holes 313 and the circular holes 322, and prevent the force from being too concentrated here, causing the fixing bolts to break and the waist-shaped circular holes 313 and the circular holes 322 to be excessively worn and deformed. The diameter of the waist-shaped circular hole 313 is 38mm, and the diameter of the circular hole 322 is 37mm. This setting is to limit the up and down swing of the super-heavy rail 1 and does not serve as a load-bearing point.

[0075] In actual life, there is no limitation on the sizes of the waist-shaped circular hole 313 and the circular hole 322 as long as the above-mentioned technical effects can be achieved.

[0076] Please refer to Figure 7 , Figure 8 , Fig. 9 and Fig.10 The second connecting structure includes a double-headed locating pin 33 and a double-hole locating seat 34. One end of the double-headed locating pin 33 is provided with a trapezoidal locating portion 331, and the other end of the double-headed locating pin 33 is provided with a positioning welding seat 332. The positioning welding seat 332 is welded to the bottom of the super-heavy rail 1. The double-headed locating pin 33 is provided with reinforcing ribs. The double-hole locating seat 34 is provided with a trapezoidal locating welding seat 341 that cooperates with the super-heavy rail 1. The double-hole locating seat 34 is provided with a locating hole 342 that cooperates with the trapezoidal locating portion 331, and is also provided with reinforcing ribs.

[0077] It should be noted that the lower plane of the super-heavy track 1 is welded with a double-hole positioning seat 34 and a double-headed positioning pin 33. When installing, the double-headed positioning pin 33 is inserted into the double-hole positioning seat 34, and the two parts are directly welded on the lower plane of the super-heavy track 1. There is a wing plate protrusion on the super-heavy track 1. Under the premise of reducing the workload and not processing the protrusion, a trapezoidal positioning welding seat 341 is used to make way for the protrusion, and it can be fixedly welded with the lower plane of the super-heavy track 1. The double-hole positioning seat 34 adopts a trapezoidal positioning structure. This part directly cooperates with the wing plate of the super-heavy track 1, which is convenient for positioning welding. Full-circle welding is adopted to increase the welding strength. The double-headed positioning pin 33 is a trapezoidal filling structure, which can be welded with the lower plane of the super-heavy track 1 and the wing plate to improve the welding strength. The double-hole positioning seat 34 and the double-headed positioning pin 33 are both integrated structures, welded at both ends of the super-heavy track 1, which can enhance the torsional strength and welding strength of the super-heavy track 1 and prevent open welding. The double-hole locating seat 34 adopts a double locating hole 342 structure as a mother part. When the super-heavy track 1 is matched, the double-headed locating pin 33 in the double-headed locating seat can be inserted into the locating hole 342. When a locomotive passes through the connection of the super-heavy track 1, the double-headed locating pin 33 can play a role in supporting the super-heavy track 1.

[0078] Among them, there is a certain movable gap between the male and female parts, which can allow a certain amount of rotation between the super-heavy rails 1. However, when the rotation exceeds a reasonable range, the cooperation of the male and female parts can also play a limiting role, which can prevent the super-heavy rails 1 from being pulled apart along the direction of the super-heavy rails 1, and prevent excessive rotation between the super-heavy rails 1, which is conducive to the smooth operation of the locomotive.

[0079] When the super-heavy track 1 rotates a certain angle within the allowable range along the contact position of the lower edge, the upper arc surface structure of the T-shaped arc seat 31 and the double-ear arc connecting seat 32 can rotate in coordination to ensure that the two arc surfaces are always in contact. When transporting super-heavy materials, this structure can bear part of the gravity and reduce the pressure of the fixing bolts. This mating surface is an arc mating surface. When the super-heavy track 1 swings up and down within the specified range along the lower fulcrum, this arc surface can also fit tightly.

[0080] There are no restrictions on the appearance structure, matching installation method and size of the double-hole positioning seat 34 and the double-headed positioning pin 33, as long as the above-mentioned technical effects can be achieved.

[0081] Please refer to Fig.11The hanging structure 4 includes a hanging seat 41, a swing structure 43 and a connecting plate 45. There are two hanging seats 41. Both ends of the hanging seat 41 are connected to the top plate through two anchor rods 42. The swing structure 43 is set as a triangular arc structure. Both ends of the swing structure 43 are connected to the hanging seat 41 through a hanging chain 44. There are two connecting plates 45. The two connecting plates 45 are arranged on both sides of the swing structure 43. The connecting plates 45 are used to connect the swing structure 43 and the double-ear arc connecting seat 32.

[0082] It can be understood that after two adjacent super-heavy rails 1 are connected by the rail connecting structure 3, they are then suspended by the hanging structure 4. After the T-shaped arc seats 31 and the double-ear arc connecting seats 32 of the two super-heavy rails 1 are matched, connecting plates 45 are installed at both ends of the double-ear arc connecting seats 32. The upper ends of the connecting plates 45 are fixed to the swing structure 43. The two ends of the swing structure 43 are connected to the hanging chains 44. The upper ends of the hanging chains 44 are connected to the hanging seats 41. The hanging seats 41 have holes 22 at both ends, and can be hung on the top plate using anchor rods 42 (or anchor cables).

[0083] Among them, the hanging chain 44 adopts a C-level chain of φ22x86, and the breaking load can reach 610kN. After preliminary preset calculation, the actual bearing capacity of a single hanging chain 44 is less than 200kN, so the safety factor can reach 3 times by using this type of chain. Each hanging chain 44 is hung by two anchor rods 42 (or anchor cables), and is connected to the two anchor rods 42 (or anchor cables) through a hanging seat 41. The hanging chain 44 is not directly matched with the anchor rod 42 (or anchor cable), which prevents the anchor rod 42 (or anchor cable) from being affected by the alternating stress of the hanging chain 44 shaking, and prevents the anchor rod 42 (or anchor cable) from breaking, thereby improving the strength and life. A total of 4 anchor rods 42 (or anchor cables) are used. The commonly used monorail hanging tracks now all use a hanging method of 2 anchor rods 42 (or anchor cables), which can increase the hanging strength and stability.

[0084] Please refer to Fig.12 The swing structure 43 includes two triangular arc straight plates 431, the tops and bottoms of the two triangular arc straight plates 431 are welded through bosses 432, both ends of the swing structure 43 are provided with first connecting holes 433 that cooperate with the hanging chain 44, and the bottom end of the swing structure 43 is provided with a second connecting hole 434 that cooperates with the connecting plate 45.

[0085] It should be noted that the swing structure 43 is welded with a symmetrical triangular arc straight plate 431, and the triangular arc structural member is forged. The second connecting hole 434 at the bottom is a hanging hole that matches the connecting plate 45. Both ends have first connecting holes 433 that match the hanging chains 44. The triangular arc symmetrical structure is adopted to ensure that the hanging force is evenly distributed on the hanging chains 44 at both ends. When a locomotive passes by, the swing structure 43 swings within a certain range, and through self-adjustment, the hanging chains 44 at both ends are in a symmetrical stress state, and there will be no single-side hanging chain 44 stress state.

[0086] Among them, in this embodiment, the first connection hole 433 and the second connection hole 434 are arranged in this way, but in actual life, there is no limitation to this, as long as the above technical effect can be achieved.

[0087] Please refer to Fig.13 Both ends of the connecting plate 45 are provided with third connecting holes 451 that cooperate with the second connecting holes 434 and the circular holes 322. The first connecting holes 433, the second connecting holes 434, the third connecting holes 451 and the circular holes 322 are all used to install the connecting bolts 6 and the anti-loosening nuts 7.

[0088] It can be understood that the connection bolts 6 (M36x160) and the anti-loosening nuts 7 (M36) are used in conjunction with the second connection holes 434 and the third connection holes 451 to achieve the fixation of the connection plate 45, the swing structure 43 and the double-ear arc connection seat 32, and the connection bolts 6 (M24x110) and the anti-loosening nuts 7 (M24) are used in conjunction with the first connection hole 433 to achieve the fixation of the hanging chain 44 and the swing structure 43. The two connection plates 45 are symmetrically installed so that the super-heavy track 1 is evenly stressed during operation. The size of the connection plate 45 is designed so that the upper swing structure 43 is at a certain distance from the track connection structure 3 on the super-heavy track 1, which can not only ensure the lowering of the hanging height, but also ensure that when the swing structure 43 swings, it will not contact and interfere with the track connection structure 3. The track connection structure 3 and the swing structure 43 are connected by two connection plates 45, which can realize the secondary floating of the suspension structure 4, avoid the rigid suspension connection between the super-heavy tracks 1, reduce the inertial impact of the locomotive on the super-heavy tracks 1, increase the buffer function, and prevent the track from twisting. The third connection hole 451 is respectively connected to the track connection structure 3 and the swing structure 43 through the connection bolt 6 and the anti-loosening nut 7. The connection plate 45 is a symmetrical structure, which does not need to distinguish the direction and is convenient for installation.

[0089] Among them, the method of using high-strength bolts to connect the connecting plate 45 and the swing structure 43 can, firstly, improve the strength. The 10.9-level bolts with M36 specifications have a breaking strength of up to 900kN to ensure the strength. Secondly, the connecting plate 45 is tightly connected with the track connecting structure 3 and the swing structure 43 to prevent the super-heavy track 1 from shaking too much left and right during operation and to prevent the super-heavy track 1 from twisting.

[0090] In the above situation, the tensioning structure 5 includes a bow-shaped shackle 51, a rear chain 52 and a transverse pull assembly. The bow-shaped shackle 51 is arranged in cooperation with the mounting hole 314. One end of the rear chain 52 is connected to the T-shaped arc seat 31 through the bow-shaped shackle 51, and the other end of the rear chain 52 is connected to the top plate. The transverse pull assembly includes two transverse pull chains 53 arranged on both sides of the T-shaped arc seat 31. One end of the transverse pull chain 53 is connected to the T-shaped arc seat 31, and the other end of the transverse pull chain 53 is connected to the top plate.

[0091] It should be noted that the symmetrical installation of two transverse pull chains 53 allows a certain angle between the two transverse pull chains 53. During installation, if there is an area on the top plate that is not suitable for installing the anchor rod 42 (or anchor cable), the position can be adjusted by adjusting the angle of the transverse pull chain 53 to facilitate installation. The T-shaped arc seat 31 has a special installation hole 314 for the transverse pull and rear pull of the super-heavy track 1. The transverse pull and rear pull of the super-heavy track 1 can be installed at this position. The T-shaped arc seat 31 is a structure directly welded on the super-heavy track 1, which has a significant anti-sway effect on the super-heavy track 1.

[0092] In summary, the super-heavy track hanging device provided by the utility model welds two existing heavy rail tracks (I140V) with the same structural dimensions together to form a frame structure, and directly welds and forms them by utilizing the structure of the existing tracks, thereby saving costs. The T-shaped arc seat 31 and the double-hole positioning seat 34 structure are adopted to increase the arc force-bearing surface on the basis of ensuring the reliable connection of the two super-heavy tracks 1, so as to bear the hanging force, reduce the wear on the middle hanging hole, and improve the torsional strength of the super-heavy track 1. The welding parts of the T-shaped arc seat 31, the double-hole positioning seat 34 and the super-heavy track 1 all adopt a trapezoidal structure, that is, bypassing the welding wing plate in the middle of the super-heavy track 1, and directly welding with the plane on the two sides of the track, without cutting off the wing plate in the middle of the super-heavy track 1, saving workload, and also improving the torsional strength of the super-heavy track 1. The lower positioning seat and the positioning hole 342 of the super-heavy track 1 all adopt a trapezoidal integrated structure, that is, bypassing the wing plate structure in the middle of the super-heavy track 1, avoiding the cutting of the middle wing plate, saving workload, and also improving the torsional strength of the super-heavy track 1. The track connection structure 3 and the swing structure 43 are connected by a connection plate 45, and are designed with a secondary floating function. The T-shaped arc seat 31 is designed with a structure for horizontal pulling and rear pulling, and is directly connected to the super-heavy track 1, which has a significant anti-sway effect on the super-heavy track 1.
