TECHNICAL FIELD
[0001] The utility model relates to a kind of roadway air door systems. BACKGROUND
[0002] Roadway air door system can be simply referred to as air door under some conditions, but a roadway air door system often includes two air doors, so that when someone or vehicle passes through, the realization of the blocking / distribution function of the roadway air door system is ensured by means of the alternate opening of the two air doors.
[0003] The current roadway air door system generally adopts single-track configuration, but it should be known that although single-track systems are also provided in the roadway, double-track systems (one uplink and one downlink) are generally configured in more roadways. Due to the influence of the current roadway air door system adopting single-track configuration, the double-track system needs to be provided with a parallel rail system at a predetermined distance of the roadway air door system to make the double-track system parallel into a single-track system so as to be connected with the single-track in the roadway air door system. Obviously, the single-track configuration adopted by the existing roadway air door system inevitably affects the transportation of the roadway. On the one hand, the parallelism of the uplink and downlink is affected due to the parallel rail, thereby affecting the transportation efficiency. On the other hand, the roadway air door system needs to be adapted to two sets of parallel rail devices, and the reliability is reduced.
[0004] Although there is currently a roadway air door system with one main and one backup two sets of roadway air door systems, but in the normal use process, the backup roadway air door system is basically in standby state, which increases the cost while actually does not produce the problem of mutual influence of uplink and downlink due to parallel rail. CONTENT OF THE UTILITY MODEL
[0005] The utility model aims to provide a double-track roadway air door system, thereby fundamentally eliminating the problems of low efficiency and reduced reliability caused by the parallel rail of uplink and downlink tracks.
[0006] According to the embodiment of the utility model, a double-track roadway air door system is provided, which basically includes the following structures:
[0007] The double-track includes left track and right track arranged in parallel with each other;
[0008] The first air door is arranged at a predetermined position of the roadway and has first left air door and first right air door arranged side by side;
[0009] The second air door is arranged at a predetermined position of the roadway and has second left air door and second right air door arranged side by side at a given distance from the first air door; and
[0010] The distance sensor or the laser sensor is used for detecting the person or vehicle running on the double tracks to determine the opening and closing of the air door. If the distance sensor is used, the distance sensor is arranged on the side of the tunnel. If the laser sensor is used, the corresponding laser sensor is arranged for each track.
[0011] The first left air door and the second left air door are used for the passing of the left track, and the first right air door and the second right air door are used for the passing of the right track.
[0012] Optionally, the distance sensor comprises a left distance sensor arranged on the left side of the tunnel and a right distance sensor arranged on the right side of the tunnel or a distance sensor arranged on one side of the tunnel.
[0013] The left distance sensor is used for detecting the person or vehicle running on the left track, and the right distance sensor is used for detecting the person or vehicle running on the right track.
[0014] If the distance sensor is arranged on one side of the tunnel, the distance sensor is used for detecting the person or vehicle running on the left track and the right track.
[0015] Optionally, the distance sensor is a laser distance sensor or an ultrasonic distance sensor.
[0016] Optionally, the first left air door and the first right air door share a first air door wall, and the first left air door and the first right air door share a first door frame on the adjacent side.
[0017] The second right air door and the second left air door share a second air door wall, and the second right air door and the second left air door share a second door frame on the adjacent side.
[0018] Optionally, the first left air door, the first right air door, the second left air door and the second right air door are all double-door air doors.
[0019] Optionally, the door frame of the corresponding air door and the corresponding door frame door hole have a pressure-avoiding sealing structure.
[0020] Optionally, the control circuit between the first air door and the second air door is connected through an interlocking circuit to ensure that only one air door between the first air door and the second air door is in an open state.
[0021] Optionally, the first air door and the second air door are an air door internal space.
[0022] Correspondingly, an auxiliary distance sensor is also arranged in the air door internal space to detect the person or vehicle entering the air door internal space.
[0023] Optionally, an audible and light alarm device is arranged on the outside of the two air doors to provide audible and light alarm signals to the person or vehicle.
[0024] Optionally, a track stopping device is arranged at a predetermined position outside the air door for linkage control of the state of the person or vehicle.
[0025] The existing air door system often needs to be parallel-tracked at the air door as a single track, while the double-track air door system according to the embodiments of the present application does not need to be parallel-tracked, thereby ensuring the relative straightness of the upward track and the downward track, i.e., reducing the bending track and the parallel-tracked device, so as to ensure the stability of the operation of the person, the vehicle or the monkey car, and to have better use reliability. Meanwhile, in order to adapt to the new air door arrangement, the ranging sensor is used in the embodiments of the present application to replace the traditional laser sensor, so as to distinguish, for example, on which track the person or vehicle is running. In addition, the mutual influence between the upward track and the downward track of the double-track air door system according to the embodiments of the present application is relatively small, and the running efficiency of the air door system is relatively high.

DETAILED DESCRIPTION
[0029] It should be known that, for an airway, generally, an upward track and a downward track are provided, and the upward track and the downward track are generally arranged in parallel, and the direction of the parallel arrangement is the transverse direction of the airway 10, which is also called the left-right direction, the width direction, etc. The extension direction of the upward track and the downward track can be called the front-rear direction, which is also called the longitudinal direction, the length direction, the head-tail direction, etc.
[0030] Under the conditions of the front-rear-left-right, the up-down direction is also determined.
[0031] In order to distinguish the up track and the down track in the lateral direction, the up track and the down track can be distinguished as the left track 3 and the right track 6, and here, the left and right are only used to distinguish the two tracks, so as to simplify the description, and do not have specific limitation.
[0032] In addition, it should be known that, for the air door system, two doors are necessary to ensure that only one door is opened and the other door is closed when a person or a vehicle passes through. In order to facilitate the description, the area between the two doors is referred to as the internal area.
[0033] The person or the person in the vehicle is generally referred to as a person-vehicle or a monkey-vehicle, but there may be a situation that a person needs to pass through the air door without a vehicle, and it should be known that the person is usually transported by a vehicle on the mine, that is, the aforementioned person-vehicle or monkey-vehicle used on the mine, and the use of "person" is specifically used to refer to the person-vehicle and the monkey-vehicle and other vehicles used to transport people.
[0034] In the embodiment of the utility model, the position where the double track is arranged in the air door system is focused on, and the sensor is adjusted, and other configurations of the air door system, including the control mode, can completely follow the corresponding configuration of the existing air door system, for example, the opening and closing time of the air door, and the existing opening and closing control mechanism can be used.
[0035] It should be known that although both of the two air doors use the double door system, the control mode does not change because of the increase of one door system, and therefore, in the embodiment of the utility model, the layout of the double track air door system is focused on, and the existing control mode can be used for the control mode, and the description is not repeated here.
[0036] For the current single track air door system, it is necessary to parallel the tracks at a predetermined position outside the air door system, and there are multiple curves, which affect the stability of the person-vehicle passing through, and in the double track air door system illustrated in the embodiment of the utility model, as shown in Figure 1 and 2 It should be known that, for the roadway transportation system, the roadway 10 itself is suitable for double tracks, in other words, the double track system is still used at the air door system, and there is no additional occupation of the roadway space, and the size can completely adapt to the roadway, and therefore the arrangement of the curves is reduced.
[0037] Referring to Figure 2 It can be more clearly understood that for the single track system, each air door only needs to be provided with one door, and the rest of the roadway 10 needs to be shielded by the door wall 26, in other words, under the condition that one door is added to each door, only the size of the door opening of the door wall 26 is required, and the roadway space is not excessively occupied.
[0038] For the convenience of description, the two tracks contained in the double track are distinguished as left track 3 and right track 6, which can also be represented as uplink track and downlink track, and the two tracks do not need to be parallel when passing through the air door system based on the embodiment of the utility model.
[0039] Further, the two air doors of the air door system are arranged at the predetermined position of the roadway, which does not change due to the adoption of the double track system, in other words, the positions where the two air doors are arranged in the traditional single track air door system of the roadway are the same as those in the double track air door system of the roadway based on the embodiment of the utility model, which will not be described here.
[0040] Unlike the traditional single track air door system, the first air door 7 of the double track air door system based on the embodiment of the utility model has a first left air door and a first right air door arranged side by side, and the second air door 16 has a second left air door and a second right air door arranged side by side. It should be known that the distance between the two air doors still belongs to the conventional configuration, which will not be described here.
[0041] The traditional sensor for detecting the object running on the track is generally a reflection type laser sensor. If a double track is used, a single reflection type laser sensor cannot identify which track the mine car is running on. If a reflection type laser sensor is used to detect the object running on the two tracks respectively, part of the reflection type laser sensor (such as the receiving end or the transmitting end) needs to be arranged between the two tracks, which has great limitations and can be used as a relatively poor choice.
[0042] However, from the control mode, the traditional reflection type laser sensor can be used with the traditional control mode, and the control node only changes in quantity, and the control mode will not change, and the overall modification cost is relatively low.
[0043] In a more preferred embodiment of the utility model, the sensor for detecting the object on the track uses a distance measuring sensor, which is arranged on the side of the roadway and is used to detect the person or vehicle running on the double track to determine the timing of the air door opening and closing.
[0044] It should be known that whether it is a traditional reflection type sensor or a distance measuring sensor applied to the double track air door system of the utility model, most of them send out a switching value, and the control mode does not change due to the selection of the sensor, therefore, the control mode can still use the existing control mode.
[0045] In addition, if the distance measuring sensor outputs a numerical value, those skilled in the art can determine how to determine which track the person or vehicle is running on without creative labor.
[0046] In addition, as a basic configuration, a comparator can be directly configured on the ranging sensor side for directly outputting an on-off value.
[0047] Correspondingly, the first left air door and the second left air door are used for passing through the left track 3, and the first right air door and the second right air door are used for passing through the right track 6. Thus, due to the adoption of double tracks, the two air doors have four air doors, which can be interlocked with each other, that is, as long as one is opened, the remaining three are closed.
[0048] In some use modes but not implementation modes, two air doors in one of the two air doors can be opened at the same time, but this use mode is not recommended, because it is difficult for people or vehicles on the two tracks to achieve synchronization, which can lead to a time period in which air doors in both air doors are opened in actual use. Therefore, as a more optimal use mode, the four air doors are interlocked with each other, one is opened, and the remaining three are closed.
[0049] Since the effective distance of the ranging sensor is relatively far, the ranging sensor can still meet the condition of judging which track the person or vehicle is located on by being configured on one side of the double track. Therefore, in some embodiments, the ranging sensor can be disposed on one side of the roadway 10.
[0050] In order to reduce misjudgment, in a more optimal embodiment, the ranging sensor includes a left ranging sensor disposed on the left side of the roadway 10 and a right ranging sensor disposed on the right side of the roadway 10.
[0051] Correspondingly, the left ranging sensor is used for detecting people or vehicles running on the left track; and the right ranging sensor is used for detecting people or vehicles running on the right track, under this condition, misjudgment can be reduced, and the judgment can be directly completed on the sensor side.
[0052] In some embodiments, that is, the ranging sensor is disposed on one side of the roadway, the ranging sensor is used for detecting people or vehicles on the left track and the right track. This configuration structure is relatively compact, and the number of ranging sensors used is relatively small, but the subsequent processing requirement is relatively high. At the same time, for coal mine safety, high reliability is a relatively high index, therefore, in a more optimal embodiment, the implementation mode of simultaneously configuring the left ranging sensor and the right ranging sensor is still adopted.
[0053] Since whether an emitter-receiver type laser sensor or a ranging sensor is adopted for detecting people or vehicles running on the track belongs to a content that can be achieved without creative labor, it will not be described here.
[0054] As for the selection of the distance measuring sensor, the laser distance measuring sensor is preferred, and the ultrasonic distance measuring sensor is the second choice. Both of the distance measuring sensors have their own advantages and belong to commonly used distance measuring devices. Those skilled in the art can select according to the working conditions, and details are not described herein.
[0055] For the convenience of description, the first left air door and the second left air door are collectively referred to as the left air door 25, and the first right air door and the second right air door are collectively referred to as the right air door 27. Figure 2 In the example structure, the left air door 25 and the right air door 27 share a vertical door frame on the adjacent side, and the overall structure is compact, and the overall sealing of the air door is relatively good.
[0056] By contrast, as shown in FIG. 1, the left air door 25 is arranged on the left side of the door wall 26, and the right air door 27 is arranged on the right side of the door wall 26. Figure 2 In the left side of the left air door 25, the sealing between the left air door 25 and the door hole formed by the door wall 26 needs to be handled, and the use of a shared vertical door frame can reduce the leakage points and be conducive to the construction of the overall sealing structure.
[0057] In addition, Figure 2 The door wall 26 shown in the figure is a wall body built at a predetermined position of the roadway 10 to form a door hole and then install the air door. Due to the deformation of the roadway 10, the door sill may be deformed, and the more the pressure points, the worse the predictability of the deformation of the door frame. For this, the patent document CN111550277A held by Shandong Kechuang Equipment Manufacturing Co., Ltd. has a very detailed description. In order to reduce the pressure points, the door frames adjacent to the left air door 25 and the right air door 27 are integrated into one door frame, which can better reduce the influence of the deformation of the roadway 10 on the air door.
[0058] As a further choice, refer to the Chinese patent document CN111550277A, and set up a pressure avoiding device or structure on the periphery of the air door. The pressure avoiding device or structure of the air door belongs to the main means used in the field to solve the influence of the deformation of the roadway on the air door, and there are relatively more related technical documents, including the aforementioned CN111550277A, which proposes some better solutions. The whole is cited here, and details are not described.
[0059] Another point to be explained is that for the aforementioned pressure avoiding device, sealing also needs to be considered, so in some implementations it is also called a pressure avoiding and sealing structure or structure, which expresses the same implementation, and details are not described herein.
[0060] Further, the conventional air door generally adopts a double-door, and in the embodiments of the present application, the first left air door, the first right air door, the second left air door and the second right air door are also double-door type air doors. As for the opening and closing mode of the air door, as mentioned above, the existing opening and closing mode is adopted, and details are not described herein.
[0061] In addition, in the Figure 1In the exemplified structure, in addition to the distance measuring sensor arranged outside the air door, four laser distance measuring sensors are arranged between the two air doors, that is, inside the air door, for auxiliary identification of people or vehicles, so as to more reliably control the opening and closing of the air door.
[0062] In a more preferred embodiment, an audible and light alarm device is arranged outside the two air doors, such as the first audible and light alarm 5 and the second audible and light alarm 20 shown in the figure, to display interactive information to people or vehicles and improve user experience. Figure 1
[0063] Further, a vehicle blocking device is arranged at a predetermined position of the track outside the air door, for linkage control of the state of people or vehicles, to avoid collision accidents caused by improper control of people or vehicles.
[0064] Correspondingly, the release and blocking states of the vehicle blocking device are adapted to the opening and closing states of the air door, which should be clearly understood by those skilled in the art.
