Description

Technical Field

[0001] This invention relates to the technical field of inclined shaft transportation protection equipment, specifically to a ground wheel mounting frame for inclined shaft transportation. Background Technology

[0002] Coal mine inclined shaft transportation commonly uses a single-rope winding wire rope hoist in conjunction with rails. Ground wheels need to be installed at the center of the two rails to reduce wire rope wear.

[0003] In related technologies, the ground wheel frame is poured and installed at the center of the track, and the axles at both ends of the ground wheel are erected on the ground wheel frame. During transportation, due to the vibration of the track bed, the concrete often becomes loose, causing the ground wheel frame to shake and tilt. This causes the tension of the steel wire rope on the vehicle to tilt, which in turn leads to the vehicle derailing during transportation and causing a transportation accident. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a ground wheel mounting frame for inclined shaft transportation, which can be stably connected to the tracks on both sides, and can withstand a certain degree of vibration, preventing the ground wheel mounting frame from shaking or tilting, thereby reducing the risk of vehicles derailing and causing transportation accidents.

[0006] The inclined shaft transportation wheel mounting frame of this invention includes a support frame and a connecting assembly. The support frame has a support groove for supporting the wheel. The connecting assembly includes a first connecting plate, a second connecting plate, and a connector. The first connecting plate is connected to the support frame. The first connecting plate has a first abutment surface for abutting the lower side of the rail bottom. The second connecting plate has a second abutment surface for abutting the upper side of the rail bottom. The first connecting plate and the second connecting plate are connected by the connector.

[0007] In some embodiments, there are multiple second connecting plates, with at least one second connecting plate located on the side of the track close to the support frame and at least one second connecting plate located on the side of the track away from the support frame.

[0008] In some embodiments, the first connecting plate has a through-hole first connecting hole, the second connecting plate has a through-hole second connecting hole, and the connector includes a bolt and a nut, wherein the bolt passes through the first connecting hole and the second connecting hole in sequence and is threadedly connected to the nut.

[0009] In some embodiments, a stiffening plate is provided between the first connecting plate and the support frame.

[0010] In some embodiments, the number of the connecting components is two, and the support frame is connected to two tracks respectively through the two connecting components.

[0011] In some embodiments, the support frame includes a first support plate and a second support plate, the first support plate and the second support plate being arranged at intervals to form a receiving area for accommodating the ground wheel, and both the first support plate and the second support plate having the support groove;

[0012] The inclined shaft transportation wheel mounting frame also includes multiple protective frames. At least one of the protective frames is located on the side of the first support plate away from the second support plate, and at least one of the protective frames is located on the side of the second support plate away from the first support plate. The protective frame is connected to the support frame. The protective frame has a protective groove. The protective groove and the support groove are arranged adjacent to each other along the axial direction of the wheel. The protective groove is open to the side facing the support groove.

[0013] In some embodiments, the first connecting plate is connected to the first support plate or the second support plate, the protective frame is disposed above the first connecting plate, and the lower side of the protective frame is attached to the upper side of the first connecting plate.

[0014] In some embodiments, the support groove has an upwardly arranged opening, and the support frame further includes a baffle and a spring member. The baffle is rotatably connected to the support frame to switch between a closed state that blocks the opening and an open state that opens the opening. The spring member is used to apply a spring force to the baffle to make the baffle tend to rotate toward the closed state.

[0015] In some embodiments, there are two baffles, namely a first baffle and a second baffle. The first baffle and the second baffle are arranged opposite to each other on the two walls of the support groove. The first baffle has a first protrusion and the second baffle has a second protrusion. In the blocked state, the second protrusion rests on the first protrusion.

[0016] In some embodiments, the inclined shaft transportation wheel mounting frame further includes a pressure detection device, which includes a pressure sensor, a controller, and an alarm. The pressure sensor and the alarm are both electrically connected to the controller. The support groove has a second limiting surface. When the second baffle is in a blocked state, the upper side of the second baffle abuts against the second limiting surface. The pressure sensor is located on the second limiting surface.

[0017] The inclined shaft transport wheel mounting frame of this invention arranges a first connecting plate on the lower side of the track, such that the first abutment surface is in contact with the lower side of the track bottom. Then, a second connecting plate is arranged on the upper side of the track bottom, such that the second abutment surface is in contact with the upper side of the track bottom. The first and second connecting plates are securely connected by connectors, thus firmly connecting the wheel mounting frame to the tracks on both sides. Compared with the installation method of the wheel frame by concrete pouring in related technologies, the connection between the first and second connecting plates can withstand a certain degree of vibration. When vibration occurs during vehicle transportation, the two can maintain a stable connection, preventing the inclined shaft transport wheel mounting frame from shaking or tilting, thereby reducing the risk of vehicle derailment and transportation accidents.

[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figure 1 and Figure 2 As shown, the inclined shaft transportation wheel mounting frame 10 of this embodiment includes a support frame 1 and a connecting assembly 2. The support frame 1 has a support groove 14 for supporting the wheel 20. The connecting assembly 2 includes a first connecting plate 21, a second connecting plate 22 and a connector 23. The first connecting plate 21 is connected to the support frame 1. The first connecting plate 21 has a first abutment surface 211 for abutting the lower side of the rail bottom 302. The second connecting plate 22 has a second abutment surface 221 for abutting the upper side of the rail bottom 302. The first connecting plate 21 and the second connecting plate 22 are connected by the connector 23.

[0035] The inclined shaft transport wheel mounting frame 10 of this invention has a first connecting plate 21 arranged on the lower side of the track 30, such that the first abutment surface 211 is in contact with the lower side of the track bottom 302. Then, a second connecting plate 22 is arranged on the upper side of the track bottom 302, such that the second abutment surface 221 is in contact with the upper side of the track bottom 302. The first connecting plate 21 and the second connecting plate 22 are securely connected by a connector 23, thus securely connecting the wheel mounting frame 10 to the tracks 30 on both sides. Compared with the installation method of the wheel 20 frame by concrete pouring in related technologies, the connection between the first connecting plate 21 and the second connecting plate 22 can withstand a certain degree of vibration. When vibration occurs during vehicle transport, the two can maintain a stable connection, preventing the wheel mounting frame 10 from shaking or tilting, thereby reducing the risk of vehicle derailment and transport accidents.

[0036] like Figure 1As shown, the vehicle is transported above two tracks 30. The track 30 includes a rail head, a rail web 301, and a rail base 302 arranged from top to bottom. The lower side of the rail base 302 is the bottom surface of the track 30, and the upper side of the rail base 302 is divided into two parts by the rail web 301. The ground wheel 20 is arranged between the two tracks 30 along the width direction of the track 30 and between the two sleepers along the length direction of the track 30, so that the bottom of the ground wheel mounting frame 10 is lower than the track 30, preventing the top surface of the ground wheel 20 from colliding with the vehicle above the track 30. At the same time, it makes it easier for the first connecting plate 21 to be inserted into the lower side of the track 30, and makes it easier to connect the ground wheel mounting frame 10 for inclined shaft transportation.

[0037] As an example, such as Figure 2 As shown, the support frame 1 is U-shaped and includes a base plate 11, a first support plate 12, and a second support plate 13. The base plate 11 is parallel to the ground. The first support plate 12 and the second support plate 13 are arranged parallel to each other and spaced apart to form a receiving area for accommodating the ground wheel 20 between the first support plate 12 and the second support plate 13. Both the first support plate 12 and the second support plate 13 have support grooves 14. The axles 201 at both ends of the ground wheel 20 are respectively supported on the two support grooves 14. The support grooves 14 have upward openings 141 so that the axles 201 of the ground wheel 20 are placed in the support grooves 14 from top to bottom.

[0038] Optionally, such as Figure 1 As shown, the second connecting plate 22 is the pressure plate of the track 30.

[0039] Therefore, the second connecting plate 22 can match the slope of the upper side of the rail base 302, eliminating the need for design and processing of the second connecting plate 22, thus reducing costs.

[0040] In some embodiments, there are multiple second connecting plates 22, with at least one second connecting plate 22 disposed on the side of the track 30 close to the support frame 1 and at least one second connecting plate 22 disposed on the side of the track 30 away from the support frame 1.

[0041] With the above settings, the first connecting plate 21 is fixed by the second connecting plate 22 located on both sides of the track 30, which can increase the connection stability of the first connecting plate 21 and the second connecting plate 22, thereby improving the stability of the inclined shaft transportation wheel mounting frame 10.

[0042] Optionally, such as Figure 1 and Figure 2 As shown, each connecting component 2 has four second connecting plates 22, which are evenly distributed on both sides of the rail web 301 of the track 30 and connected to the same first connecting plate 21 via connectors 23.

[0043] This allows for a secure connection of the inclined shaft transportation wheel mounting frame 10.

[0044] In some embodiments, the first connecting plate 21 has a through-hole 212, the second connecting plate 22 has a through-hole 22, and the connector 23 includes a bolt and a nut. The bolt passes through the first connecting hole 212 and the second connecting hole in sequence and is threadedly connected to the nut.

[0045] The first connecting plate 21 and the second connecting plate 22 are connected to each other by bolts and nuts, which makes disassembly and assembly relatively convenient. The connection of bolts and nuts can withstand a certain degree of vibration and is not easy to loosen during vibration, thereby preventing the inclined shaft transportation wheel mounting frame 10 from shaking or tilting, and reducing the risk of vehicles derailing and causing transportation accidents.

[0046] In some embodiments, such as Figure 1 As shown, a stiffening plate 3 is provided between the first connecting plate 21 and the support frame 1.

[0047] By setting the stiffening plate 3, the stability of the connection between the first connecting plate 21 and the support frame 1 can be improved, thereby further improving the overall stability of the inclined shaft transportation wheel mounting frame 10.

[0048] Optionally, the first connecting plate 21, the support frame 1, and the stiffening plate 3 are welded together.

[0049] In some embodiments, the number of connecting components 2 is two, and the support frame 1 is connected to two rails 30 respectively through the two connecting components 2.

[0050] By setting two sets of connecting components 2, the inclined shaft transportation wheel mounting frame 10 can be connected to the two side rails 30, so that the inclined shaft transportation wheel mounting frame 10 is subjected to balanced force, thereby providing more stable support for the wheel 20.

[0051] In some embodiments, such as Figure 3 As shown, the inclined shaft transportation wheel mounting frame 10 also includes multiple protective frames 16. At least one protective frame 16 is located on the side of the first support plate 12 away from the second support plate 13, and at least one protective frame 16 is located on the side of the second support plate 13 away from the first support plate 12. The protective frame 16 is connected to the support frame 1. The protective frame 16 has a protective groove 161. The protective groove 161 and the support groove 14 are arranged adjacent to each other along the axial direction of the wheel 20. The protective groove 161 is open on the side facing the support groove 14.

[0052] It is known that, such as Figure 2As shown, the axles 201 at both ends of the ground wheel 20 are respectively installed in two support grooves 14. At the same time, in order to make the ground wheel 20 stable, the axles 201 at both ends of the ground wheel 20 protrude outward from the first support plate 12 and the second support plate 13 respectively. During vehicle transportation, when the wire rope is slack, the wire rope is easy to detach from the ground wheel 20 and get caught on the two axles 201. When the wire rope is tightened, it will cause the ground wheel 20 to fall and roll into the alley or the lower parking lot, causing workers to be injured by falling objects, which poses a significant safety hazard.

[0053] By setting up the protective frame 16, the part of the shaft 201 that protrudes from the support groove 14 is located in the protective groove 161, which can protect the end of the shaft 201. Even if the wire rope detaches from the ground wheel 20, it is difficult to get caught on the shaft 201, thereby reducing the risk of the ground wheel 20 being snagged and reducing safety hazards.

[0054] In some embodiments, such as Figure 1 and Figure 3 As shown, the first connecting plate 21 is connected to the first support plate 12 or the second support plate 13, and the protective frame 16 is located above the first connecting plate 21, with the lower side of the protective frame 16 attached to the upper side of the first connecting plate 21.

[0055] By attaching the lower side of the protective frame 16 to the upper side of the first connecting plate 21, the steel wire rope can be prevented from entering the lower side of the protective frame 16 and exerting an upward force on the protective frame 16, thereby compromising the stability of the inclined shaft transportation wheel mounting frame 10.

[0056] As an example, such as Figure 3 As shown, the protective frame 16 is made of angle steel, and the protective groove 161 is the area enclosed by the two side plates of the angle steel. The protective frame 16 is welded to the support frame 1 and the first connecting plate 21. The protective frame 16 extends vertically, and the lower end face of the protective frame 16 is attached to the upper side face of the first connecting plate 21.

[0057] In some embodiments, such as Figures 4 to 6 As shown, the support groove 14 has an upwardly arranged opening 141. The support frame 1 also includes a baffle and a spring member 41. The baffle is rotatably connected to the support frame 1 so that the baffle can switch between a closed state of blocking the opening 141 and an open state of opening the opening 141. The spring member 41 is used to apply a spring force to the baffle so that the baffle tends to rotate toward the closed state.

[0058] If the wire rope is severely slack, it may become entangled in the part of the shaft 201 located between the first support plate 12 and the second support plate 13, which could cause the ground wheel 20 to fall off, or the ground wheel 20 may detach from the support groove 14 under the action of other external forces, posing a safety hazard.

[0059] By setting a baffle, the ground wheel 20 can be prevented from detaching from the support groove 14, thereby reducing the safety hazard caused by the ground wheel 20 falling off. In addition, by rotating the baffle, when installing the ground wheel 20, the ground wheel 20 is placed into the support groove 14 from top to bottom. The ground wheel 20 can force the baffle to rotate into the support groove 14, switching the opening 141 to the open state. After the ground wheel 20 enters the support groove 14, the baffle can automatically switch to the closed state under the action of the elastic member 41, thereby preventing the ground wheel 20 from detaching from the support groove 14 while improving the convenience of the ground wheel 20 installation.

[0060] Optionally, the baffle is rotatably connected to the support frame 1 via the pivot 44. The elastic element 41 is a torsion spring, which is mounted on the pivot 44. The torsion spring is used to apply torque to the baffle, so that the baffle has an upward rotation tendency, so that the opening 141 tends to be kept in the closed state.

[0061] In some embodiments, such as Figure 5 and Figure 6 As shown, there are two baffles, namely the first baffle 42 and the second baffle 43. The first baffle 42 and the second baffle 43 are arranged opposite to each other on the two groove walls of the support groove 14. The first baffle 42 has a first protrusion 421 and the second baffle 43 has a second protrusion 431. In the blocked state, the first protrusion 421 is placed on the upper side of the first protrusion 421.

[0062] By adopting the above settings, the area covered by the rotation of the baffle can be reduced, thereby reducing the size of the mounting groove 15 and making it more convenient for the design and installation of the baffle. At the same time, through the cooperation of the first protrusion 421 and the second protrusion 431, the relative position of the first baffle 42 and the second baffle 43 is more stable, so as to provide better blocking effect on the ground wheel 20.

[0063] In some embodiments, such as Figure 5 As shown, the inclined shaft transportation wheel mounting frame 10 also includes a pressure detection device, which includes a pressure sensor 5, a controller and an alarm. The pressure sensor 5 and the alarm are both electrically connected to the controller. The support groove 14 has a first limiting surface 151. When the first baffle 42 is in the blocking state, the upper side of the first baffle 42 abuts against the first limiting surface 151. The pressure sensor 5 is located on the first limiting surface 151.

[0064] With the above settings, the pressure sensor 5 can monitor the pressure applied by the first baffle 42 to the first limiting surface 151 and transmit the pressure signal to the controller. The controller is set with a pressure threshold. When the pressure detected by the pressure sensor 5 exceeds the pressure threshold, it indicates that the ground wheel 20 moves upward and squeezes the first baffle 42. In other words, the ground wheel 20 may be dislodged from the support groove 14 due to external force. At this time, the controller sends a signal to the alarm, and the alarm sounds to remind the operator to handle the situation in time.

[0065] Furthermore, since the first protrusion 421 is positioned above the second protrusion 431, when the ground wheel 20 moves upward and presses against the second baffle 43, the pressure exerted by the ground wheel 20 on the second baffle 43 is transmitted to the first limiting surface 151 through the first baffle 42, thereby triggering the alarm.

[0066] As an example, such as Figure 5 and Figure 6 As shown, each of the two sidewalls of the support groove 14 has a mounting groove 15. When the first baffle 42 and the second baffle 43 are the openings 141 of the windshield support groove 14, the first baffle 42 and the second baffle 43 are respectively located in the two mounting grooves 15. The top groove wall of the mounting groove 15 used to accommodate the first baffle 42 is the first limiting surface 151, and the top groove wall of the mounting groove 15 used to accommodate the second baffle 43 is the second limiting surface 152. The first limiting surface 151 and the second limiting surface 152 are respectively used to limit the upward rotation angle of the first baffle 42 and the second baffle 43, so that the first baffle 42 and the second baffle 43 remain horizontal in the blocked state.

[0067] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any changes, modifications, substitutions and variations made to the above embodiments by those skilled in the art are within the protection scope of the present invention.
