Description

  The present invention relates to a transport train test apparatus for testing a travel drive system of a transport train drawn from a transport route.

For example, Patent Document 1 discloses a maintenance carriage for a transportation train in which a transportation train is moved from a transportation route to another frame so that maintenance work such as inspection and repair can be performed. This well-known maintenance cart is equipped with a train support rail connected to the train guide rail of the transport line, and maintenance work such as inspection and repair is performed on the transport train transferred from the transport line to the train support rail. However, it is long enough to retract the transportation train, and it is impossible to actually test the transportation train that has undergone maintenance work in this maintenance carriage. .
JP 2003-212124 A

  Therefore, the transport train that has performed maintenance work such as repair on the maintenance cart as described above will be returned to the transport line as if the failure has been repaired. In the case of an electric train, since the failure was not sufficiently repaired, a failure accompanied by a phenomenon such as an abnormal stoppage of the transfer train after re-entering the transfer line was reproduced, and other transfer operations on the transfer line were performed. There was a risk of a huge impact. Of course, when a driving test as described above is necessary, a limited time zone such as nighttime can be used so that the transfer work by other transfer trains in operation is not affected, but in any case, Depending on the result of the running test, it is necessary to return the transport train to the maintenance carriage and perform repair work, which results in low work efficiency and high work costs.

  An object of the present invention is to provide a test apparatus for a transportation train that can solve the conventional problems as described above, and the means thereof is shown with reference numerals of embodiments to be described later. A pair of front and rear followers that rotatably support the train support rail 22 connected to the train guide rail 6 of the transport line and the traveling drive wheel 7 of the transport train 1 moved to a fixed position of the train support rail 22. Support rollers 26a and 26b, load applying means 27 for applying a running resistance corresponding to the transport train 1 during load transportation, power supply and signal transmission means 29 for supplying power and a travel control signal to the transport train 1 , A rotational speed detector 30 for detecting the rotational speed of the pair of front and rear driven support rollers 26a, 26b, and a display for displaying the traveling speed of the transport train 1 based on the rotational speed detected by the rotational speed detector 30. And it has a configuration that includes a stage 42.

  Thus, the transport train 1 in the transport line is connected to the train support rail 22 of the test device 19 from the transport line in a state where the train support rail 22 of the test device 19 is connected to the train guide rail 6 of the transport line. However, when repair work or the like is necessary before the test, the work is first performed before the test device 19 is transferred or in the state where the test device 19 is transferred. Thereafter, the transport train 1 is moved to a fixed position where the travel drive wheel 7 is fitted between the pair of front and rear driven support rollers 26a and 26b by a manual push operation or the like. Is provided with a running resistance corresponding to the time of carrying the cargo, and the feeding and signal transmission means 29 supplies the feeding train 1 with a feeding power and a traveling control signal, so that the traveling driving wheel 7 is driven at the set traveling speed. Drive to rotate. As a result, the pair of front and rear driven support rollers 26a and 26b are driven to rotate by the frictional drive wheels 7 of the transport train 1, and the rotational speed is detected by the rotational speed detector 30, and the rotational speed is detected. The traveling speed of the transport train 1 is displayed on the display means 42 based on the detected rotational speed of the container 30.

  The load applying means 27 includes a cylinder unit 34 that urges the transport train 1 downward via an engagement tool 35 detachably engageable with the transport train 1. can do. Specifically, the transport train 1 includes a power trolley 2 having a driving wheel 7 for traveling, a free trolley 3 having an idle wheel 15, and a load bar 4 connecting both trolleys 2 and 3. In the case where the load W is suspended through the hanger 5 suspended from the load bar 4, the load applying means 27 includes the load bar as described in claim 3. 4 can be constituted by a cylinder unit 34 that pulls down the load bar 4 via an engaging tool 35 that can be freely engaged and disengaged from the cylinder 4.

  According to a fourth aspect of the present invention, the load applying means 27 includes a load corresponding to a running resistance when the transport train 1 does not transport the load W, and the transport train 1 transports the load W. It is desirable that the load corresponding to the running resistance during actual running can be set selectively.

  Furthermore, as described in claim 5, the power supply and signal transmission means 29 uses the detachable connector 14 that connects the current collecting unit 12 and the control device 13 included in the transport train 1 to use the control device. The power supply and signal line 37 connected to 13 can be used. In addition, as described in claim 6, it is desirable to provide a train lock means for fixing the transport train 1 moved to a fixed position of the train support rail 22 at the fixed position. Specifically, as described in claim 7, the load applying means 27 that urges the transport train 1 downward through an engagement tool 35 that is detachable with respect to the transport train 1 is also used. Can be made.

  Further, this type of transport train 1 is provided with a detected member 45 to be detected by a train detector disposed at a branch point or a stop station in the transport line. As described, a train presence detector 46 that detects the transport train 1 moved to a fixed position of the train support rail 22 by using the detected member 45 provided in the transport train 1 is also provided. The operation state of the train presence detector 46 can be displayed on the display means 47.

  According to the transport train test apparatus of the present invention, the travel drive wheels of the transport train in a state of being supported at a fixed position on the train support rail of the test apparatus, the transport train itself is stopped. The actual driving speed of the driving train at that time, that is, the driving speed in the load transfer state of the transfer train determined based on the peripheral speed of the driven support roller (actual driving) Travel speed) is displayed on the display means, and the operator compares the speed set value given as the travel control signal with the travel speed value displayed on the display means, Since it is possible to determine whether or not there is a problem, it is possible to eliminate all the problems in the case where the repaired transport train has to be re-introduced into the transport line and the running test must be performed in the load transport state.

  In addition, as a method of giving the running resistance corresponding to the load train to the transport train, a method of giving a rotational resistance to the pair of front and rear driven support rollers that support the drive wheels for running of the transport train can be considered. In addition, the frictional resistance between the driving wheel for driving and the driven support roller must be sufficiently increased, but conversely, the large frictional resistance between the two will give a large traveling resistance during actual traveling to transport the load. In this case, the driving wheel for traveling over the driven support roller may cause a practical test to fail. Of course, it can be adopted as a method of giving a small running resistance during idling without carrying a load, but an actual running test often has to assume an actual running when carrying a load. In this case, according to the second aspect of the present invention, the necessary running resistance can be easily applied to the transport train by simply adjusting the fluid pressure applied to the cylinder unit, and the given running resistance can be increased. Since the force that pushes the driving drive wheel downward between the pair of front and rear driven support rollers increases, the driving drive wheel rides up between the pair of front and rear driven support rollers even when it is necessary to give a large driving resistance. There is no risk of the transport train going out of control and it can be tested safely.

  Moreover, according to the structure of Claim 3, the train for conveyance was provided with the power trolley provided with the drive wheel for driving | running | working, the free trolley provided with the idle wheel, and the load bar which connects both trolleys. In the case where the load is suspended via the hanger suspended from the load bar, the hanger is present or not present (when the hanger is removed when being introduced into the test apparatus). Regardless of whether the load bar is used or not, the running test can be performed with high accuracy by equally applying running resistance to both the front and rear trolleys in the same manner as when carrying the actual load.

  Furthermore, according to the structure of Claim 4, the driving | running | working test equivalent to the time of the empty driving | running | working in which the conveyance train does not convey a load is also attained, and the effect of a driving | running | working test can be heightened. According to the configuration of claim 5, power supply and signal transmission to the control device for the transport train can be easily and easily performed using a detachable connector that connects the current collecting unit provided in the transport train and the control device. The test apparatus of the present invention can be easily put into practical use. Further, according to the configuration of claim 6, the train for transportation can be securely held at a fixed position by the train lock means, and the runaway of the train for transportation can be prevented. According to this configuration, the train locking means and the load train can be used both as load applying means for biasing downward, so that it can be implemented at a lower cost than when both are provided separately.

  Further, according to the configuration of the eighth aspect, not only can the presence of the detection plate provided in this type of transportation train and the mounting position thereof be checked based on the operating state of the train presence detector, but also the transportation can be performed during the test. It is possible to check whether the train is in a fixed position from the operating state of the train presence detector, so necessary control based on the detection signal of the train presence detector, for example, to the cylinder unit of the load applying means It is also possible to automatically start supplying fluid pressure.

  A specific embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 and 2, reference numeral 1 denotes a transport train, in which a power trolley 2 and a free trolley 3 are connected by a load bar 4. Thus, the load W is suspended below the load bar 4 via a pair of front and rear hangers 5 and conveyed along a conveying line. One guide rail 6 for suspending the power trolley 2 and the free trolley 3 is installed on the transport line.

  The guide rail 6 has an I-shaped cross section, and the power trolley 2 has a traveling drive wheel 7 that rolls on the upper horizontal rail portion 6 a of the guide rail 6, and this drive wheel 7 is rotationally driven via a speed reducer 8. The motor 9 with a brake, the horizontal rails 6a and 6b on the upper and lower sides of the guide rail 6 on both sides of the driving wheel 7 from both the left and right sides, and the vertical shaft roller 10 for steadying and the vertical plate 6c of the guide rail 6 are laid on one side. A detachable current collecting unit 12 slidably contacting the power feeding and signal line group 11 and a control device 13 are provided, and the connection cord 12a on the current collecting unit 12 side and the connection cord 13a on the control device 13 side are detachable. It is connected via a connector 14. The free trolley 3 is provided with an idle wheel 15 that rolls on the upper horizontal rail portion 6 a of the guide rail 6, and a steady-state vertical shaft roller 16 that is the same as the steady-state vertical shaft roller 10 of the power trolley 2. It has been. The guide rail 6 is suspended from a beam member 18 on the conveyance line via a bracket 17 coupled to the vertical plate portion 6c.

  Thus, the transport train 1 having the above-described configuration is configured to control the motor 9 that is rotationally driven by the power supplied from the power supply and signal line group 11 based on the travel control signal supplied from the power supply and signal line group 11. By controlling 13, the load W that travels along the guide rail 6 at a predetermined speed and is suspended by the hanger 5 can be transported along the transport line.

  A repair line is branched to the transport line, and a test device 19 is connected to the end of the guide rail 6 of the repair line. This test device 19 is a cart type equipped with a free wheel 20 and a ground bolt 21 for fixing the cart position, and supports the same train support rail 22 as the guide rail 6 via a support frame 23. . The connection between one end of the train support rail 22 and the free end of the guide rail 6 on the repair line is performed, for example, by connecting the vertical plates 6c and 22c of the rails 6 and 22 in a state where the end faces are in contact with each other to the connection plate 24 and the bolt nut. 25 can be combined.

  As shown in FIGS. 1 and 3, the test device 19 includes a pair of front and rear driven support rollers 26 a that rotatably support the driving wheel 7 for traveling of the transport train 1 located at a fixed position on the train support rail 22. , 26b, load applying means 27 for applying a running resistance to the transport train 1 at the fixed position, and a control device 28. The control device 28 includes a power supply and signal transmission means 29 for supplying power and a travel control signal to the transport train 1, and a rotation speed detector (linkage coupled to one of the front and rear driven support rollers 26a and 26b. And an operation panel 31 having a display unit for displaying the traveling speed of the transporting train 1 based on the number of rotations detected by a pulse encoder 30).

  The pair of front and rear driven support rollers 26a and 26b are pivotally supported between a pair of left and right bearing plates 32 interposed at a place where the train support rail 22 is divided forward and backward, and the peripheral surface runs on the transportation train 1 side. A process for increasing the frictional resistance with the driving wheel 7 is applied, and the driving wheel 7 is less likely to slip with respect to the driven support rollers 26a and 26b. The driven support rollers 26a and 26b are at the same level as when the traveling drive wheel 7 supported between the rollers 26a and 26b is supported on the train support rail 22 as shown in the figure. When pivotally supported between the bearing plates 32, it is necessary to get over the one roller 26b in order to fit the traveling drive wheel 7 between the two rollers 26a, 26b. Is supported by a lifting / lowering member, and the lifting / lowering member is lifted by a cylinder unit, a screw-type jack mechanism or the like in a state where the transport train 1 is stopped at a fixed position, and the driving wheels for traveling by both rollers 26a and 26b. It is also possible to configure so that 7 can be lifted and supported slightly. Further, as shown in FIG. 3, for example, as shown in FIG. 3, a bearing plate is used so that the steady-state vertical shaft roller 10 of the power trolley 2 functions even when the driving wheel 7 is fitted and supported between the driven support rollers 26a and 26b. The steady-state vertical shaft roller 10 can be configured to abut on the outer surfaces of the upper and lower sides of 32.

  The load applying means 27 is provided for the cylinder unit 33 arranged vertically, a hook-like engagement tool 35 provided at the upper end of the piston rod 34 protruding upward, and the cylinder unit 33. The fluid pressure generating means 36 supplies a fluid pressure (pneumatic pressure, etc.), and the fluid pressure generating means 36 is controlled by the control device 28. The engaging member 35 is pivotally supported at the upper end of the piston rod 34 by a horizontal support shaft 35a parallel to the length direction of the train support rail 22 so as to be able to swing left and right, as shown in FIG. By switching to the retracted position, it is possible to avoid interference with the load bar 4 and the like when the transport train 1 is moved to a fixed position where the traveling drive wheel 7 is supported between the driven support rollers 26a and 26b. In the state where the transport train 1 has reached a fixed position, the engagement tool 35 is swung up and around the horizontal support shaft 35a, so that the power train 2 between the power trolley 2 and the free trolley 3 of the transport train 1 can be used. The engaging tool 35 can be put on the load bar 4 at the center position. In this state, by supplying fluid pressure to the cylinder unit 33 and lowering the piston rod 34, a downward load can be applied to the transport train 1 via the load bar 4 by the engagement tool 35.

  As shown in FIG. 3B, the power supply and signal transmission means 29 provided in the control device 28 includes a connection cord 37 that can be connected to the connection cord 13 a on the control device 13 side provided in the transportation train 1 using the connector 14. Thus, the same connector plug (or connector socket) 37a as that attached to the terminal of the connection cord 12a on the current collecting unit 12 side is attached to the terminal of the connection cord 37.

  Hereinafter, the function of the control device 28 provided in the test apparatus 19 having the above-described configuration will be described together with a method of using the test apparatus 19. First, the transport train 1 branched from the transport line to the repair line and subjected to necessary repairs is transferred from the guide rail 6 of the repair line to the train support rail 22 of the test apparatus 19 by a manual push operation or the like. Of course, the train support rail 22 of the test device 19 is used as a repair line for performing maintenance work such as repair on the transport train 1, and the transfer train 1 branched from the transport line and transferred to the train support rail 22 of the test device 19 is used. Then, maintenance work such as repair may be performed.

  In the transport train 1 transferred to the train support rail 22 of the test device 19, the current collecting unit 12 is disconnected in a state where the connector 14 is detached and the connection cord 13 a of the control device 13 and the connection cord 12 a of the current collection unit 12 are separated. Although the hanger 5 has also been removed, as shown in FIG. 3B, the hanger 5 and the equipment on the test device 19 side, such as the load applying means 27, do not interfere with each other, and the transport train 1 Can be moved to a fixed position on the train support rail 22 so that it can be transferred to the test device 19 with all the equipment on the side of the transport train 1 such as the hanger 5 attached. May be. Thus, the transport train 1 transferred to the train support rail 22 of the test device 19 is moved to a fixed position along the train support rail 22 by a manual push operation or the like, and the traveling drive wheels 7 are moved to a pair of front and rear. The driven support rollers 26a and 26b are fitted and supported. At this time, as shown in FIG. 3A, the piston rod 34 of the cylinder unit 33 in the load applying means 27 is in the ascending limit position, and the engagement tool 35 is in a retracted posture in which it is turned sideways.

  When the traveling drive wheel 7 is moved to the above-mentioned fixed position, as shown in FIG. 3B, the connection cord 37 which is the power supply and signal transmission means 29 on the test device 19 side is connected to the connection cord 13a on the transport train 1 side. Is connected to the connector 14 via the connector 14, the engaging tool 35 of the load applying means 27 is swung upright and the hook portion thereof is positioned on the center position of the load bar 4 of the transport train 1, and preparation for starting the test is completed. Make

  As shown in FIG. 4, the operation panel 31 of the control device 28 is provided with, for example, a low speed button 38a, a medium speed setting button 38b, and a high speed setting button 38c as speed setting buttons. There is provided a setting button 39a and a load setting button 39b during actual travel when the hanger 5 is used to suspend and convey a load W of a predetermined weight. First, the load setting button 39b during actual travel is pressed to set the load. I do. By this load setting operation, the control device 28 gives a load setting signal 36a to the fluid pressure generating means 36, and the fluid pressure generating means 36 supplies a predetermined fluid pressure to the cylinder unit 33 based on the given load setting signal 36a. As a result, the engaging tool 35 pulled down by the piston rod 34 presses the load bar 4 of the transport train 1 downward, and the same load is applied to the transport train 1 when the predetermined weight load W is suspended and transported. Can be given to. In this state, when any one of the speed setting buttons 38a to 38c is operated to set the speed, the control device 28 causes the power supply and signal line group 11 when the transportation train 1 is on the transportation line. A speed setting signal 40 and a motor driving power 41 corresponding to the motor driving power and a speed setting signal given to the control device 13 of the transport train 1 from the power collecting unit 12 are connected to the connection cord as the power feeding and signal transmission means 29. 37 and 13a, the control device 13 operates the motor 9 of the power trolley 2 at a predetermined rotational speed and rotationally drives the driving wheel 7 for traveling. Become.

  When the traveling drive wheel 7 is rotationally driven, the pair of front and rear driven support rollers 26a and 26b on the test device 19 side are frictionally driven to rotate at the same peripheral speed as the peripheral speed of the drive wheel 7. Is detected by the rotation speed detector 30, and the rotation speed detection signal 30 a is fed back from the rotation speed detector 30 to the control device 28. The control device 28 calculates the traveling speed of the transport train 1 at that time based on the feedback number detection signal 30a fed back according to a preset program, a digital numerical display provided on the operation panel 31, etc. The traveling speed calculated by the display means 42 is displayed. Therefore, the operator determines whether or not the driving wheel 7 for traveling by the motor 9 is normally driven from the traveling speed value displayed on the display means 42 and the set speed set by the speed setting buttons 38a to 38c. Can be determined.

  The above running test can be repeated by changing the speed set by the speed setting buttons 38a to 38c. Further, when the transport train 1 to be transferred to the test apparatus 19 is equipped with all the equipment including the hanger 5, the load applying means 27 is not operated, that is, from the cylinder unit 34 via the engagement tool 35. By performing the above-described traveling test in a state where no pulling force is applied to the load bar 4, it is possible to perform a traveling test during idle traveling in which the transport train 1 does not suspend and transport the load W. In addition, as shown in the example, when the transport train 1 with the hanger 5 and the like removed is tested for running, a pulling force (load load) corresponding to the total weight of the removed equipment such as the hanger 5 is applied. It is also possible to give the load bar 4 as described above by the applying means 27 and perform a running test during idle running in which the transport train 1 does not suspend and transport the load W.

  The operation panel 31 may be provided with display means 43 for displaying the load load value set by the load setting buttons 39a and 39b. Furthermore, it is also possible to configure so that the set load can be adjusted stepwise or steplessly. In addition, the operation panel 31 shown in FIG. 4 includes display means 44 such as an ammeter for displaying the current value of the motor driving power supplied to the control device 13 on the transport train 1 side via the connection cords 37 and 13a. Is provided.

  As shown in FIG. 4, the transport train 1 is provided with a member 45 to be detected that is a detection target of a train detector (such as a magnetic sensor or a photoelectric sensor) disposed at a predetermined position on the transport line side. The detected member 45 is detected when the transport train 1 is positioned at a fixed position of the test device 19, that is, when the traveling drive wheel 7 is positioned at a fixed position supported between the pair of front and rear driven support rollers 26a and 26b. A train presence detector (magnetic sensor, photoelectric sensor, etc.) 46 can be provided, and a display means 47 such as a lamp operated by a train presence signal 46a from the train presence detector 46 can be provided. . In this case, it is possible not only to confirm that the detected member 45 of the transport train 1 exists at a predetermined position by turning on the display means 47, but also to detect the detection operation of the train presence detector 46 in the running test. By setting it as one condition for the start, the running test can be performed safely.

  As shown in FIG. 4, the motor 9 that drives the traveling drive wheel 7 of the transport train 1 is also provided with a constant braking electromagnetic brake 9a that is open when energized while traveling, When the train fixed position detector 48 for detecting the member to be detected disposed at the train stop position is operated, the power supply to the motor 9 is cut off at the same time as the power supply to the brake electromagnetic brake 9a is cut off at the same time. Acts so that the transportation train 1 is braked and stopped. When the train fixed position detector 48 operates to stop the transportation train 1 from braking, the control device 13 on the transportation train 1 side always energizes the braking electromagnetic brake 9a again after the set time elapses to release the brake. However, when the transport train 1 is located at a fixed position of the test apparatus 19, a detected member 49 that can be detected by the train fixed position detector 48 is attached to the test apparatus 19 side. The operation of the train fixed position detector 48 in the transport train 1 operating on the transport line is confirmed by the sound generated from the electromagnetic brake 9a when the constant braking electromagnetic brake 9a on the motor 9 side is deenergized. Can do.

  The power supply and signal transmission means 29 is not limited to the power supply and signal line 37 used in the above embodiment. For example, a power supply and signal line group identical to the power supply and signal line group 11 installed on the guide rail 6 of the transfer line is installed on the train support rail 22 of the test apparatus 19 and transferred to the test apparatus 19 for transfer. The power collection unit 12 of the train 1 is not removed, and the power supply and control signals are applied to the transport train 1 from the power supply and signal line group laid on the train support rail 22 via the current collection unit 12 of the transport train 1. It can also be configured. In this case, the power supply and signal transmission means 29 is a power supply and signal line group laid on the train support rail 22.

  Moreover, although the test device 19 is configured as a movable carriage, it may be a test device fixedly connected to the repair line.
