Description

Technical Field

[0001] The invention belongs to the technical field of mining equipment, and in particular relates to a blocking system after a mine car is unhooked in an inclined shaft. Background Art

[0002] Inclined mine cars are commonly used in underground mining and transportation. Tracks are usually laid in the mine for driving, and the mine cars are connected to each other with hooks, so that large quantities of materials can be transported each time. The driving force of the mine car comes from the winch installed at the entrance of the cave, and the winch pulls the mine car out of the mine through a steel rope.

[0003] Due to the large amount of transportation by the mine car, after a certain period of use, the steel rope or the hook between the two mine cars or the mine car and the steel rope will produce fatigue defects, which is easy to cause unhooking accidents; in order to prevent other accidents caused by unhooking, it is necessary to stop the unhooked mine car as soon as possible, which is called an anti-runaway system; the blocking method currently adopted is to set a blocking device, set a blocking bar that can be turned up above the track, and fix a steel pipe on the blocking rail, and insert a steel rope into the steel pipe to stop the rail car sliding down. For example, Chinese patent CN207670421U discloses a new type of anti-runaway device for mining. Although the scope of application of this device is relatively wide, there are also some shortcomings, such as: when the blocking rail, steel pipe, and steel rope stop the rail car, the pressure of the entire rail car is all pressed between the last car and the blocking device, which is very easy to cause damage to the rail car and derailment due to excessive pressure. Therefore, a blocking system is needed, which can disperse the pressure on the rail car when blocking the rail car and reduce the blocking accidents. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems and provide a blocking system after the mine car is unhooked in the inclined shaft, so as to block the rail car, reduce the impact on the rail car during blocking, and improve the blocking safety.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a blocking system after the mine car is unhooked from the inclined shaft, comprising a rail car and a plurality of columns, the columns being arranged on both sides of the rail car;

[0006] A vertically arranged blocking piece is provided on the column, and hooks are provided on both sides of the rail vehicle. After the rail vehicle is unhooked, the hooks can be hooked with the blocking piece;

[0007] One end of the blocking member is connected to the buffer member, and the other end is connected to the first winch assembly.

[0008] The technical effect of the above improvement is: by setting up the blocking member and the hook, the rail vehicle can be blocked, and driven by the first winch assembly and the buffer member connected at both ends of the blocking member, the rail vehicle can be gradually slowed down to avoid the impact caused by the direct collision of the rail vehicle and improve the safety of the blocking.

[0009] In order to disperse and block different rail vehicles.

[0010] As a further improvement of the above technical solution, a plurality of groups of vertically arranged support members are provided on the side of the column, the blocking member passes through the support members, and there is a gap between each group of support members;

[0011] The hooks are at different heights on the sides of different rail cars, and the hooks can pass through the gaps and blocking members to hook onto each other.

[0012] The technical effect of the above improvement is: hooks of different heights and blocking pieces of different sections are set on different rail vehicles, so that when blocking, the blocking pieces of different sections and the hooks of corresponding heights can be hooked with each other, and the blocking pieces and different rail vehicles can be hooked with each other, so that the rail vehicles blocked by the blocking pieces of different sections are only impacted by a single rail vehicle, thereby achieving the effect of dispersed blocking and improving the safety of blocking.

[0013] In order to avoid greater wear between the blocking member and the supporting member when the blocking member is pulled to move.

[0014] As a further improvement of the above technical solution, a connection box is arranged at the end of the support member, and a guide wheel which can contact with the blocking member is rotatably arranged in the connection box.

[0015] The technical effect of the above improvement is: by setting the guide wheel, the friction generated by the movement can be changed into sliding friction, thereby reducing the wear of the blocking member on the supporting member.

[0016] In order to prevent the blocking member from wearing the hook during blocking.

[0017] As a further improvement of the above technical solution, the hook includes an extension rod, on which a roller that can contact the blocking member is rotatably arranged, and guide plates are arranged on both sides of the roller, which guide the blocking member so that the blocking member is hung on the roller.

[0018] The technical effect of the above improvement is: through the provision of the roller, friction can be changed into rolling friction, thereby reducing wear, and under the guidance of the guide plate, the blocking member can smoothly contact the roller, thereby improving the accuracy of mutual hooking.

[0019] In order to prevent the support parts from interfering with the rail car during normal driving and transportation of the rail car.

[0020] As a further improvement of the above technical solution, the support member and the column are hinged to each other, and a pull rod group is connected between the support member and the column, and the pull rod group is connected to a driving source for driving the support member to fold;

[0021] When the support is folded, avoid the hook to avoid driving interference.

[0022] The technical effect of the above improvement is that when the rail vehicle is running normally, by controlling the support member to fold, the support member and the hook can avoid each other, avoiding interference with the normal running of the rail vehicle.

[0023] In order to quickly pull the rail car back upwards after blocking it.

[0024] As a further improvement of the above technical solution, a cross arm is fixedly arranged on the top of the column, a swing rod arranged in a drooping manner is hinged on the cross arm, a pull rope is passed through the swing rod, and the end of the pull rope has a hook that can be clamped on the end of the swing rod, and the hook can be hooked with a hanging rod arranged on the rail car;

[0025] A second hoisting assembly connected to the pull rope is fixedly arranged on the cross arm.

[0026] As a further improvement of the above technical solution, the end of the swing rod has a concave concave limit groove on the concave concave limit groove;

[0027] The hook is provided with a cone which can be matched with the shrinking mouth, and the cone is provided with a limit platform which is matched with the limit groove.

[0028] The technical effect of the above improvement is: the hanging rod can be hooked by the provided pull rope and hook, and the rail car can be pulled back upward under the winding of the second winch assembly to facilitate the connection of the unhooked rail car.

[0029] In order to further limit the structure of the buffer component and improve the buffer effect.

[0030] As a further improvement of the above technical solution, a plurality of pulleys are arranged on the cross arm, and the blocking member passes upward around the pulleys and is connected to the buffer member;

[0031] The buffer component is a buffer hydraulic cylinder.

[0032] The technical effect of the above improvement is: by setting the buffer hydraulic cylinder, the buffer tension on the blocking member can be gradually increased, thereby achieving a soft blocking effect on the rail vehicle.

[0033] In order to further define the structure of the first hoisting assembly.

[0034] As a further improvement of the above technical solution, the first hoisting assembly includes a coaxially arranged roller, a brake assembly, and a clutch assembly, the input end of the clutch assembly is connected to a reducer, and the reducer is connected to the motor.

[0035] The technical effect of the above improvement is that the first winch assembly can wind up the blocking member to pull the rail car back upward, and the provided brake assembly can brake and slow down the roller to play a buffering role on the blocking member.

[0036] In order to improve the stability of the column.

[0037] As a further improvement of the above technical solution, a cable is connected to the column to prevent it from tipping over.

[0038] The technical effect of the above improvement is that the column can be pulled by the set rope to prevent the column from being pulled down due to excessive impact. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0052] Embodiment 1:

[0053] As the instruction manual Figure 1-9 As shown in the figure, it is the embodiment 1 of the present application. As a specific embodiment of the present invention, the specific structure of the present invention is: a blocking system after the mine car inclined shaft is unhooked, including a rail car 10 and a plurality of columns 11, the columns 11 are arranged on both sides of the rail car 10, and the columns 11 can be referred to the attached manual. Figure 1 As shown, the rail vehicle 10 is traveling on a track set on the ground, and the columns 11 are fixedly set on the ground and located on both sides of the track. The columns 11 are connected with cables 27 to prevent them from tipping over. The cables 27 are also fixed on the ground and arranged obliquely. Figure 4 As shown;

[0054] A vertically arranged blocking member 12 is provided on the column 11. In the present embodiment, the blocking member 12 is a steel rope, a blocking cable, etc. Hooks 13 are provided on both side surfaces of the rail vehicle 10. One end of the blocking member 12 is connected to a buffer member 17, and the other end is connected to a first hoisting assembly 14, wherein the buffer member 17 is a buffer hydraulic cylinder. In the present embodiment, the buffer member 17 is fixedly provided on the column 11. The first hoisting assembly 14 specifically includes a coaxially arranged roller 141, a brake assembly 142, and a clutch assembly 143. The input end of the clutch assembly 143 is connected to a reducer 144, and the reducer 144 is connected to a motor. A cross arm 20 is fixedly provided on the top of the column 11. The cross arm 20 and the column 11 form a door frame. A plurality of pulleys 26 are provided on the cross arm 20. The blocking member 12 passes upward around the pulley 26 and is connected to the buffer member 17.

[0055] When the rail car 10 is unhooked, the rail car 10 will slide down along the inclined shaft track, the hook 13 can be hooked with the blocking member 12, the blocking member 12 is extended under the pull of the hook 13, the buffer member 17 can buffer one end of the blocking member 12, and the brake assembly 142 can brake to slow down the pulling speed of the blocking member 12, thereby forcing the rail car 10 to stop.

[0056] Please refer to the instruction manual Figure 1 , 2 , 3, and 4, further optimized on the basis of the above embodiment: a plurality of groups of vertically arranged support members 15 are provided on the side of the column 11. In this embodiment, each group of support members 15 is specifically provided with two, and the blocking member 12 passes through the support members 15, and there is a gap 16 between each group of support members 15; a connection box 151 is provided at the end of the support member 15, and a guide wheel 152 that can contact with the blocking member 12 is rotatably provided in the connection box 151, and the guide wheel 152 is mainly contacted with the steel rope for guidance, converting the movement of the blocking member 12 into rolling friction, thereby reducing the wear of the steel rope;

[0057] In addition, the hook 13 is arranged at different heights on the sides of different rail vehicles 10, and the hook 13 can pass through the gap 16 and hook with the blocking member 12. Figure 4 As shown, in this figure, two adjacent rail vehicles 10 are drawn, and h is the height difference of the hooks 13 on the two different rail vehicles 10, that is, the heights of the hooks 13 set on the sides of different rail vehicles 10 are different. In order to meet the actual situation, in this embodiment, at least the heights of the hooks 13 on the two adjacent rail vehicles 10 are guaranteed to be different, and the hooks 13 on multiple non-adjacent rail vehicles 10 can be allowed to be at the same height; by setting multiple hooks 13 at different heights, the blocking member 12 is divided into multiple sections by the support member 15, and different hooks 13 correspond to different sections. The blocking members 12 of different heights are hooked together, so that when intercepting the railcar 10, multiple railcars 10 connected together can be individually intercepted by the blocking members 12 of different segmented heights, thereby reducing the squeezing of the railcar 10 on the lower side and reducing the impact of the entire railcar 10, thereby playing a role of dispersed blocking; and after intercepting, the blocking member 12 can be wound by controlling the first winch assembly 14, thereby pulling the railcar 10 back upward, and when pulling it back, the blocking member 12 is subjected to segmented force, and different railcars 10 are pulled back in a dispersed manner, which is equivalent to using a movable pulley, making it easier to pull back.

[0058] Please refer to the instruction manual Figure 1 , 36, further optimized on the basis of the above embodiment: the hook 13 includes an extension rod 131, in order to prevent the extension rod 131 from scratching the surrounding people or objects when driving, the extension rod 131 is hinged on the side of the rail car 10, and a support rod hingedly arranged with the side of the rail car 10 is also provided on the extension rod 131, and the support rod can be disassembled from the extension rod 131 so that the extension rod 131 can be retracted to one side of the rail car 10, and the extension rod 131 is rotatably provided with a support member that can be connected with the blocking member 12 The roller 132 contacts the blocking member 12, and guide plates 133 are arranged on both sides of the roller 132. The guide plates 133 guide the blocking member 12 so that the blocking member 12 can easily enter the roller 132 and hang on the roller 132. The roller 132 can contact the blocking member 12 during the blocking process, and the friction between the blocking member 12 and the blocking member 12 is converted into sliding friction to reduce wear. The guide plates 133 can facilitate the contact between the blocking member 12 and the roller 132, so that the roller 132 and the blocking member 12 can be more easily hooked with each other.

[0059] Please refer to the instruction manual Figure 2 As shown, it is further optimized on the basis of the above embodiment: in order to facilitate the normal driving of the rail vehicle 10, in this embodiment, the support member 15 and the column 11 are hinged to each other, and a tie rod group 18 is connected between the support member 15 and the column 11. In this embodiment, the tie rod group 18 is provided with two hinge rods hinged to each other, and a driving source for driving the support member 15 to fold is connected to the tie rod group 18. In this embodiment, the driving source is a driving hydraulic cylinder, and the hydraulic cylinder is hinged to the column 11;

[0060] When the rail vehicle 10 moves outward normally, the hydraulic cylinder is started, which drives the tie rod group 18 to bend and drives the support member 15 to fold. When the support member 15 is folded, the hook 13 can be avoided to avoid interference with driving. When the rail vehicle 10 passes through the column 11, the hydraulic cylinder drives the tie rod group 18 to move, so that the support member 15 is folded to a state perpendicular to the column 11. At this time, a triangle is formed between the tie rod group 18, the support member 15 and the column 11. Figure 2 , the stability of the support member 15 can be ensured.

[0061] Please refer to the instruction manual Figure 1 , 4As shown in , 7, 8, and 9, it is further optimized on the basis of the above embodiment: a swing rod 21 arranged in a drooping manner is hinged on the cross arm 20, and the swing rod 21 is specifically a hollow pipe. A pull rope 22 is penetrated through the swing rod 21, and the end of the pull rope 22 has a hook 23 that can be clamped on the end of the swing rod 21. Specifically, the end of the swing rod 21 has a concave inwardly contracting concave opening 211, and the concave opening 211 has a concave limiting groove 212; the hook 23 is provided with a cone 231 that can cooperate with the concave opening 211, and the cone 231 is provided with a limiting platform 232 that cooperates with the limiting groove 212. When the swing rod 21 and the hook 23 are mutually engaged and engaged, the limiting platform 232 is inserted into the limiting groove 212, and it can be ensured that when the swing rod 21 and the hook 23 are clamped together, the opening of the hook 23 can only be in an upward or downward state (with the attached Figure 4 For example, Figure 4 The state of the middle hook 23 is that the opening is over downward), when the opening of the hook 23 is upward, human intervention turns the hook 23 to the downward state, and a second winch assembly 24 interconnected with the pull rope 22 is fixedly provided on the cross arm 20;

[0062] Specifically, when the rail vehicle 10 is moving forward normally, the swing arm 21 can contact the hanging rod 25, but the hook 23 will not hook the hanging rod 25. When the rail vehicle 10 is unhooked, the hook 23 can hook the hanging rod 25 set on the rail vehicle 10, and the hook 23 will be pulled to pull the pull rope 22 out of the second winch assembly 24. By starting the motor connected to the second winch assembly 24, the second winch assembly 24 can roll up the pull rope 22 to quickly pull the rail vehicle 10 back upward. This setting is mainly because the pulling back speed through the blocking member 12 is too slow.

[0063] Embodiment 2:

[0064] Please refer to the instruction manual Figure 10-11 As shown, this is Example 2 of the present application. This example is another form of Example 1. Compared with Example 1, the main difference is that in this example, the buffer 17 is fixedly arranged on the bottom surface, and the blocking member 12 passes through the pulley 26 and is downwardly connected to the output shaft of the buffer 17. This arrangement can reduce the tension on the column 11 during buffering deceleration.

[0065] The specific working principle of the present invention is: when the rail vehicle 10 is transported forward normally, the hydraulic cylinder connected to the support member 15 is first controlled to start, driving the support member 15 to fold to avoid the hook 13, so as to reduce the interference of the support member 15 on the driving of the rail vehicle 10. When the rail vehicle 10 passes the column 11, the hydraulic cylinder is controlled to start and drive the support member 15 to fold to a state perpendicular to the column 11;

[0066] When uncoupling occurs on the railcar 10, the uncoupling railcar 10 slides downward. During the sliding process, the hook 23 will hook the hanging rod 25, and the hook 13 will hook the blocking member 12. The blocking member 12 will be stretched by the hook 13. Under the buffering deceleration of the buffer member 17 and the brake assembly 142, the blocking member 12 is decelerated to stop the railcar 10. By setting a plurality of hooks 13 and a plurality of sections of blocking members 12 to be hooked with each other, it can be ensured that the railcar 10 on the lower side is subjected to a smaller impact force. The stopped railcar 10 can be pulled back upward after starting the motor connected to the second winch assembly 24 or the motor connected to the first winch assembly 14, so as to reconnect the uncoupling railcar 10 and the uncoupling railcar 10 with each other.

[0067] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0068] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. The above is only a preferred implementation of the present invention. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the protection scope of the present invention.
