Description

Technical Field

[0001] The present invention relates to the technical field of mine transportation and hoisting, and specifically to a coal mine non-uniform speed pressure-controlled monkey car operation system and operation method. Background Art

[0002] At present, there are two main types of monkey car systems in operation in coal mines: fixed monkey cars and self-hanging monkey cars. The former is to fix monkey cars at equal intervals on the wire rope in advance, and passengers can directly ride the monkey car without hooking the monkey car themselves; the latter is that there is no monkey car fixed on the running wire rope, and passengers need to hook the monkey car themselves before riding the monkey car. No matter which monkey car riding method is used, it has its application advantages. Fixed monkey cars do not require manual hooking of monkey cars, so riding is more convenient and safe. Although self-hanging monkey cars require manual hooking of monkey cars, they do not need to fix a large number of monkey cars throughout the journey, thus saving a large number of monkey cars and operating costs. Therefore, these two types of monkey cars are widely used in coal mines. However, there is a common monkey car riding safety problem that cannot be ignored in these two types of monkey car riding methods. Since the running speed of the monkey car is fixed, the running speed of the monkey car remains unchanged when riding the monkey car at the station or arriving at the station. There are safety hazards when passengers get on and off the monkey car, and it is easy for passengers to fall off the car and the monkey car to get off the rope. In addition, the fixed monkey car riding method requires a large number of monkey cars to be fixed. The economic cost of operating the monkey car system for long-distance operation is relatively high, and it also consumes a lot of energy. As for the self-hanging monkey car riding method, it is not only inconvenient to ride because the monkey car needs to be hooked by oneself, but also increases the safety hazard of riding the monkey car. When hooking the monkey car, it is easy to fall off the car and the monkey car will be untied. Especially when carrying other items, the safety hazard of the self-hanging monkey car is more prominent.

[0003] Utility model patent 201720648283.x discloses a weight-sensing monkey car seat, including a seat handle with an upper end mounted on a wire rope through a rope grip; a seat cushion mounted on the seat handle; and a weight sensor mounted on the seat cushion for detecting the weight of the rider, the weight sensor being used to send the detected signal to the monkey car controller. The utility model can automatically detect whether there are miners sitting on the monkey car, providing a guarantee for the intelligent operation of the monkey car. However, this technology still cannot solve the problem of potential safety hazards when people get on and off the monkey car after it arrives at the station. Contents of the invention

[0004] The technical problem to be solved by the present invention is that the speed of the monkey car running system cannot be controlled in stages, and there are safety hazards when people get on and off the monkey car after the monkey car arrives at the station.

[0005] The present invention solves the above technical problems through the following technical means:

[0006] A method for operating a non-uniform speed pressure-controlled monkey car in a coal mine, which is applied to a non-uniform speed pressure-controlled monkey car operating system in a coal mine. The non-uniform speed pressure-controlled monkey car in a coal mine includes a uniform speed track, a first transition track, a second transition track, and a control mechanism; the first transition track and the second transition track are respectively connected at the stations at both ends of the uniform speed track, and the two ends of the uniform speed track overlap with the corresponding ends of the first transition track and the second transition track respectively; the first transition track and the second transition track are higher than the uniform speed track, and the first transition track and the second transition track are arranged in parallel and at intervals with the uniform speed track; the lateral arrangement width of the first transition track, the second transition track and the uniform speed track is less than that of the monkey car. The width of the car gripper; the control mechanism includes a controller, a first drive mechanism, a second drive mechanism, a third drive mechanism, a first pressure sensor, a second pressure sensor, and a third pressure sensor; the first pressure sensor and the second pressure sensor respectively detect the pressure of the first transition track and the second transition track, and the third pressure sensor detects the pressure of the uniform speed track, and are respectively connected to the controller for communication, and the controller controls the first drive mechanism, the second drive mechanism, and the third drive mechanism to open and close according to the pressure information, the first drive mechanism and the second drive mechanism respectively drive the first transition track and the second transition track to run, and the third drive mechanism drives the uniform speed track to run;

[0007] The method for operating a non-uniform speed pressure regulating monkey car in a coal mine comprises the following steps:

[0008] S01. In the initial state, the uniform velocity track, the first transition track, and the second transition track are in a stationary state;

[0009] S02. When the monkey car gripping cable is hung on the first transition track into the station, the first pressure sensor obtains pressure information and sends the pressure information to the controller, which controls the first drive mechanism to run at a first speed;

[0010] S03. When someone wants to ride on the monkey car, the first pressure sensor senses the pressure information and sends the pressure information to the controller, which controls the first drive mechanism to run at a second speed;

[0011] S04. When the monkey car passes through the junction of the uniform speed track and the transition track, the third pressure sensor obtains a pressure signal and sends the pressure signal to the controller, which controls the third drive mechanism to run at a third speed; at the same time, the pressure information of the first pressure sensor disappears, and the controller controls the first drive mechanism to stop running;

[0012] S05. When the monkey car arrives at the exit site and passes through the junction of the uniform speed track and the second transition track, the second pressure sensor obtains pressure information and sends the pressure information to the controller, which controls the second drive mechanism to start, and the third pressure sensor pressure information is small, and the third drive mechanism is controlled to stop running;

[0013] S06. When the personnel get off the monkey car, the second pressure sensor in the transition track out of the station detects the pressure information and sends the pressure information to the controller, which controls the second drive mechanism to stop running;

[0014] S07. After the monkey car leaves the station or is recovered, the pressure information of the second pressure sensor disappears, and the controller controls the second driving mechanism to stop running.

[0015] Furthermore, the first driving mechanism includes a first driving wheel and a first driven wheel, the first transition track is sleeved on the first driving wheel and the first driven wheel, a first roller is arranged between the first driving wheel and the first driven wheel, the first roller is located between the first driving wheel and the first driven wheel to raise the first transition track; the first pressure sensor is fixed to the rotating shaft of the first roller; the second driving mechanism includes a second driving wheel and a second driven wheel, the second transition track is sleeved on the second driving wheel and the second driven wheel, a second roller is arranged between the second driving wheel and the second driven wheel, the second roller is located between the second driving wheel and the second driven wheel to raise the second transition track; the second pressure sensor is fixed to the rotating shaft of the second roller.

[0016] Furthermore, there are two first rollers, which are respectively located between the first driving wheel and the first driven wheel; there are two second rollers, which are respectively located between the second driving wheel and the second driven wheel.

[0017] Furthermore, a third roller for supporting the uniform speed track is fixed on the rotating shafts of the lower vehicle end of the first transition track and the upper vehicle end of the second transition track; the third roller is at the same height as the highest point of the driving wheel or the driven wheel on the same rotating shaft; and the third pressure sensor is fixed at the rotating shaft of the third roller.

[0018] Furthermore, the operating system includes a left operating unit and a right operating unit that are arranged in a mirror image; the left operating unit and the right operating unit both include the uniform speed track, the first transition track, the second transition track, and a control mechanism.

[0019] Furthermore, the first driving wheel, the first driven wheel, the second driving wheel, the second driven wheel, the first roller and the second roller corresponding to the left operating unit and the right operating unit are coaxially fixed on the corresponding rotating shafts through bearings.

[0020] Furthermore, the rotating shaft is fixed by vertical rods and horizontal beams.

[0021] The advantages of the present invention are:

[0022] The present invention achieves that when the monkey car is at a station, the first transition track and the second transition track are higher than the uniform speed track, and the gripper hangs on the transition track without causing pressure on the uniform speed track, and facilitates a smooth transition to the uniform speed track, thereby enabling different pressure sensors to collect pressure information at different stages, providing a basis for effectively controlling the track running speed of the monkey car station.

[0023] This system not only effectively solves the potential safety hazards when monkey cars get on and off at stations, but also solves the problem of high operating costs of fixed monkey cars, providing technical guarantee for the safe operation of the monkey car system in coal mines.

[0024] The first transition track can be raised as much as possible throughout the entire process by means of the two first rollers, so as to avoid the uniform speed track being subjected to pressure in the transition track section and reduce control errors.

[0025] Fixing the third roller coaxially with the driving wheel or driven wheel at the disembarkation end of the first transition track and the boarding end of the second transition track can instantly collect the pressure of the monkey car falling on the uniform speed track, improve control accuracy, and achieve seamless operation of the monkey car.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1 As shown, this embodiment discloses a coal mine non-uniform speed pressure control monkey car operation system, including a uniform speed track 7, a first transition track 5, a second transition track, and a control mechanism; the uniform speed track 7, the first transition track 5, and the second transition track are all steel wire ropes.

[0033] The stations at both ends of the uniform track 7 are connected to the first transition track 5 and the second transition track respectively; and the two ends of the uniform track 7 overlap with the corresponding ends of the first transition track 5 and the second transition track respectively, so as to facilitate the smooth transition of the monkey car. It should be noted that since the second transition track has the same structure as the first transition track 5, Figure 1 Only the connection structure between the first transition track 5 and the uniform speed track 7 is shown, and the following description is also based on the first transition track 5.

[0034] In this embodiment, the two transition tracks are higher than the uniform speed track 7, and the first transition track 5, the second transition track and the uniform speed track 7 are arranged in parallel and spaced apart; the lateral arrangement width of the first transition track 5, the second transition track and the uniform speed track 7 is smaller than the width of the monkey car grip; when the monkey car is at the station, the monkey car grip is buckled on the transition track and the uniform speed track 7 at the same time. Since the transition track and the uniform speed track 7 are at different heights, the pressures they bear are different, providing corresponding control signals for the control mechanism.

[0035] like Figure 2 , Figure 3 As shown, the control mechanism includes a controller, a first drive mechanism, a second drive mechanism, a third drive mechanism, a first pressure sensor 9, a second pressure sensor (not shown in the figure), and a third pressure sensor (not shown in the figure); the first pressure sensor 9 and the second pressure sensor respectively detect the pressure of the first transition track 5 and the second transition track, and the third pressure sensor detects the pressure of the uniform speed track 7, and are respectively communicated with the controller. The controller controls the first drive mechanism, the second drive mechanism, and the third drive mechanism to open and close according to the pressure information, and the first drive mechanism and the second drive mechanism respectively drive the first transition track 5 and the second transition track to run, and the third drive mechanism drives the uniform speed track 7 to run.

[0036] Specifically, the first driving mechanism includes a first driving wheel 3 and a first driven wheel 3', a first transition track 5 is sleeved on the first driving wheel 3 and the first driven wheel 3', a first roller 4 is arranged between the first driving wheel 3 and the first driven wheel 3', and the first roller 4 is located between the first driving wheel 3 and the first driven wheel 3' to raise the first transition track 5; a first pressure sensor 9 is fixed at the rotating shaft 10 of the first roller 4;

[0037] The second driving mechanism has the same structure as the first driving mechanism, including a second driving wheel (not shown in the figure) and a second driven wheel (not shown in the figure), the second transition track is sleeved on the second driving wheel and the second driven wheel, and a second roller (not shown in the figure) is arranged between the second driving wheel and the second driven wheel. The second roller will be located between the second driving wheel and the second driven wheel to raise the second transition track; the second pressure sensor is fixed at the rotating shaft 10 of the second roller.

[0038] A third roller 2 for supporting the uniform speed track 7 is also fixed on the rotating shaft 10 at the lower end of the first transition track 5 and the upper end of the second transition track; the third roller 2 is at the same height as the highest point of the driving wheel or the driven wheel on the same rotating shaft 10; the third pressure sensor is fixed at the rotating shaft 10 of the third roller 2.

[0039] In this embodiment, there are two first rollers 4, which are respectively located between the first driving wheel 3 and the first driven wheel 3', and are as close to the first driving wheel 3 and the first driven wheel 3' as possible; there are two second rollers, which are respectively located between the second driving wheel and the second driven wheel, and are as close to the second driving wheel and the second driven wheel as possible, so as to facilitate raising the end of the transition track.

[0040] In this embodiment, the operating system can be unidirectional, or can realize bidirectional operation through two left and right operating units. The specific structure of bidirectional operation is:

[0041] like Figure 2 As shown, the running system includes a left running unit and a right running unit that are arranged in a mirror image; the left running unit and the right running unit both include a uniform speed track 7, a first transition track 5, a second transition track, and a control mechanism.

[0042] The first driving wheel 3, the first driven wheel 3' (not shown in the figure), the second driving wheel (not shown in the figure), the second driven wheel (not shown in the figure), the first roller 4, and the second roller (not shown in the figure) corresponding to the left running unit and the right running unit are coaxially fixed on the corresponding rotating shaft 10 through the bearing 6. The rotating shaft 10 is fixed to the crossbeam through the vertical rod 1.

[0043] In this embodiment, the first driving wheel 3 , the second driving wheel, and the driving wheel of the uniform speed track 7 are all driven by corresponding motors 8 .

[0044] Working principle:

[0045] By making the first transition track 5 and the second transition track higher than the uniform track 7, when the monkey car is at the station, the rope gripper will not cause pressure on the uniform track 7 when hanging on the transition track, and it is convenient to smoothly transition to the uniform track 7, so that different pressure sensors can collect pressure information at different stages, providing a basis for effectively controlling the track running speed of the monkey car station. When the monkey car is entering the station, when it is hung on the first transition track 5 (the uniform track 7 is also within the rope gripper range of the rope gripper, but does not bear pressure), the first pressure sensor 9 collects the weight of the monkey car, and the controller controls the first drive mechanism to run at a slower speed according to the weight, so that people can get on the car; after the people get on the car, the first sensor collects the weight of the people, and the controller controls the first drive mechanism to run at a faster speed. When the monkey car runs to the intersection of the first transition track 5 and the uniform track 7 and falls on the uniform track 7, the third sensor collects the weight of the people, and the controller controls the third drive mechanism to run at a set speed. When the monkey car runs to the exit station, the monkey car enters the second transition track under the action of inertia. At this time, since the uniform speed track 7 is lower than the second transition track, the pressure of the third pressure sensor disappears, and the controller controls the third drive mechanism to stop running. At the same time, the second pressure sensor collects the weight information of the personnel and controls the second drive mechanism to run at a speed slower than the uniform speed to facilitate people getting off the car. After the people get off the car, the second pressure sensor collects the weight information of the monkey car. At this time, the controller controls the second drive mechanism to run at a slower speed until the monkey car is recovered and the pressure information of the second pressure sensor disappears. The controller controls the second drive mechanism to stop running. At this point, the complete operation ends.

[0046] like Figure 4 As shown, in this embodiment, an operation method of a coal mine non-uniform speed pressure control monkey car operation system includes the following steps:

[0047] S01. In the initial state, the uniform speed track 7, the first transition track 5, the second transition track, and the control mechanism are in a stationary state;

[0048] S02. When the monkey car needs to be operated, the monkey car gripper is hung on the first transition track 5 of the station, the first pressure sensor 9 at the rotating shaft 10 of the first roller 4 senses the pressure information of the monkey car, and sends the pressure information to the controller, the controller controls the instant start of the first motor 8, and the first motor 8 drives the first driving wheel 3 to drive the first transition track 5 to run at a speed of 0.25m / s;

[0049] S03. When someone wants to ride on the monkey car, the first pressure sensor 9 senses the pressure information of the human body weight and sends the pressure information to the controller, which controls the first motor 8 to drive the first drive wheel 3 to drive the first transition track 5 at a speed of 0.4m / s;

[0050] S04. When the monkey car passes the junction of the uniform track 7 and the transition track, and the monkey car falls on the uniform track 7, the third pressure sensor obtains a pressure signal and sends the pressure signal to the controller, and the controller controls the third drive mechanism to run at a uniform speed; at the same time, the pressure information of the first pressure sensor 9 disappears, and the controller controls the first drive mechanism to stop running;

[0051] S05. When the monkey car arrives at the exit site and passes through the junction of the uniform speed track 7 and the second transition track, the monkey car enters the second transition track under the action of inertia, the second pressure sensor obtains pressure information, and sends the pressure information to the controller, the controller controls the second drive mechanism to start, the monkey car decelerates to 0.4 m / s, and at the same time, the pressure information of the third pressure sensor is small, and the third drive mechanism is controlled to stop running;

[0052] S06. When the person gets off the monkey car, the second pressure sensor in the transition track at the exit station detects that the pressure is reduced and sends the pressure information to the controller, which controls the second drive mechanism to decelerate to 0.25m / s;

[0053] S07. After the monkey car leaves the station or is recovered, the pressure information of the second pressure sensor disappears, and the controller controls the second driving mechanism to stop running.

[0054] According to the above method, the rope running speed of the monkey car station can be effectively controlled, and at the same time, the normal operation of the wire rope running throughout the whole process is not affected. The automatic adjustment of the driving speed of the monkey car when passing the station is realized through the pressure regulation system. Among them, the third roller and the first driving wheel or the second driving force are fixed on the same rotating shaft, and the spacing between the two rollers is 2mm. When the pressure sensed by the pressure sensor 9 is less than 2Kg, the motor 8 stops working; when the pressure sensor 9 senses a gravity of 2-35Kg, the rotation speed of the motor 8 is 0.25m / s; when the pressure sensor 9 senses a gravity greater than 35Kg, the rotation speed of the motor 8 is 0.4m / s.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
