The invention provides a loading device for loads of a monorail framework and an axle, which comprises a framework 1, an axle 2 connected with the framework 1, and a base 3 which is arranged on the lower end surface of the middle part of the framework 1 and used for restricting the position freedom degree of the framework 1.
It should be noted that the above loads include torque and linear loads, that is to say, the loading means of the monorail frame and axle load are used to apply torque and linear loads to the frame 1 and/or the axle 2.
A travelling wheel tool 4 is arranged at one end of the axle 2 facing the inside of the framework 1, and a motor substitute tool 5 is arranged at one end facing the outside of the framework 1; the walking wheel tool 4 is connected with a force actuator and a torque actuator, the force actuator is used for applying a three-way linear load to the walking wheel tool 4, and the torque actuator is used for applying a torque to the walking wheel tool 4; the motor substitute tool 5 is also connected with a force actuator for applying a three-way linear load to the motor substitute tool 5.
Both the force actuator and the torque actuator can be arranged with reference to prior art actuators.
The frame 1 and the axle 2 of the loading device of the loads of the monorail frame and the axle are connected together according to the actual assembly relationship, in order to apply linear load torque to the frame 1 and the axle 2 simultaneously, two ends of the axle 2 are respectively connected with a walking wheel tool 4 and a motor substitute tool 5, the walking wheel tool 4 and the motor substitute tool 5 are used for simultaneously applying linear load and torque which cannot be simultaneously applied originally to the axle 2 and the frame 1, and the size and the direction of the linear load applied to the axle 2 and the frame 1 and the size and the direction of the torque applied to the axle 2 and the frame 1 can be freely combined.
The loading device for the load of the monorail framework and the axle provided by the invention is further described below by combining the attached drawings and the embodiment.
On the basis of the above embodiment, the force actuator is used for applying a three-directional linear load, and actuators in the prior art, for example, six actuators are adopted, each three actuators are divided into one group, two groups of actuators are respectively connected to the end of the traveling wheel tooling 4 and the end of the motor substitute tooling 5, and the three actuators in each group of actuators respectively extend along three axes of a spatial rectangular coordinate system.
Illustratively, the force actuators include three first actuators 91 connected to the traveling wheel tooling 4 and three second actuators 92 connected to the motor substitute tooling 5; the three first actuators 91 are connected to the end part of the travelling wheel tool 4 and respectively apply linear loads to the travelling wheel tool 4 along the transverse direction, the longitudinal direction and the vertical direction; the three second actuators 92 are connected to the ends of the motor replacement tool 5, respectively, and apply linear loads to the motor replacement tool 5 in the lateral direction, the longitudinal direction, and the vertical direction, respectively.
The torque actuator may be implemented using two conventional actuators. Specifically, two third actuators 93 are connected to the end face of the traveling wheel tooling 4 on the same side at intervals, the loading directions of the two third actuators 93 are opposite, and the torque actually applied to the traveling wheel tooling 4 is adjusted by adjusting the size of any one third actuator 93 and adjusting the distance between the two third actuators 93.
It can be seen that when the frame 1 is connected to an axle 2, the loading means of the load of the monorail frame and axle are fitted with three first actuators 91, three second actuators 92 and two third actuators 93; when the frame 1 is connected with two axles 2, the plurality of actuators are combined into one group, one axle 2 is connected with one group of actuators, and the two axles 2 are respectively connected with two groups of actuators.
Two axles 2 are connected to the frame 1 as an example. Two axles 2 are respectively connected to two sides of the framework 1, and two ends of any one axle 2 are respectively connected with a travelling wheel tool 4 and a motor substitute tool 5. In order to simplify the connection between the walking wheel tool 4 and the plurality of actuators, the walking wheel tool 4 is of a hexahedral structure, any one side surface of the hexahedron is provided with a mounting position for fixedly connecting the actuators, the heads of the actuators are connected towards the mounting position, and the tails of the actuators extend towards the direction far away from the framework 1.
The two third actuators 93 of the same travelling wheel tooling 4 are connected to the same side surface, and at least two groups of mounting positions with different intervals are arranged on the side surface for conveniently adjusting the torque applied by the two third actuators 93.
The motor substitute tool 5 is connected with three second actuators 92, for convenience of installation, the end of the motor substitute tool 5 is provided with three pairwise vertical installation surfaces, and one second actuator 92 is fixed perpendicular to one installation surface.
On the basis of the above embodiment, the monorail framework is connected with the base 3 of the loading device of the load of the axle by a pair of vertical tools 6, a pair of traction seat restraining tools 7 for simulating a pull rod and a pair of transverse stopping restraining tools 8 for simulating transverse stopping.
The six tools are all arranged along the length direction of the base 3, the pair of transverse stopping constraint tools 8 are symmetrically arranged in the middle of the base 3, the pair of traction seat constraint tools 7 are respectively arranged on two sides of the pair of transverse stopping constraint tools 8 and are symmetrically distributed, and the pair of vertical tools 6 are respectively arranged on two sides of one transverse stopping constraint tool 8 and are symmetrically distributed.
The base 3 is mounted below the cross member 11 of the frame 1 and extends in the same direction as the cross member 11. The base 3 is connected to the cross member 11 through the plurality of tools, thereby restricting the degree of freedom in the position of the frame 1.
Wherein, the vertical tool 6 is used for restricting the vertical freedom degree of the framework 1; the traction seat constraint tool 7 is connected to a component by referring to an actual pull rod and is used for constraining the longitudinal degree of freedom of the framework 1; the transverse stop restraining tool 8 is connected to the member with reference to the actual transverse stop for restraining the transverse degree of freedom of the frame 1.
The vertical tool 6 may include a chassis 61 and a rotating shaft 62; the base plate 61 is fixed on the upper end surface of the base 3, the rotating shaft 62 is vertically inserted into the base plate 61, and the other end of the rotating shaft 62 is inserted into the connecting hole 12 of the framework 1.
Since the chassis 61 is in contact with the connecting seats at the lower end surfaces of the two ends of the beam 11 of the frame 1, there is a space between the beam 11 and the base 3 according to the structural arrangement of the frame 1, and for this reason, a supporting seat is usually further provided between the chassis 61 and the base 3.
The specific arrangement form of the traction seat constraint tool 7 can comprise a fixed seat 71 and a pin shaft 72; the fixed seat 71 is fixedly connected to the upper end surface of the base 3, and the pin shaft 72 is pivoted in the fixed seat 71 and is used for connecting a frame 1 traction seat of the frame 1; the axial direction of the pin 72 is the same as the length direction of the base 3.
The base 3 is connected with the framework 1 through a pin shaft 72, the base and the framework can rotate around the pin shaft 72, when the framework 1 bears the vertical load, the framework 1 restrains the tool 7 through the traction seat to realize sinking and floating movement, and the effect same as that of the pull rod is achieved.
Two installation seats 111 which are opposite at intervals are arranged in the middle of the cross beam 11, and the two transverse stopping restraining tools 8 extend into the space between the two installation seats 111 and are respectively connected with the inner sides of the two installation seats 111. When the transverse load is transmitted to the mounting seats 111 through the framework 1, the transverse load acts on one of the mounting seats 111, the transverse stopping restraining tool 8 connected with the mounting seat 111 plays a stopping role, and the transverse stopping restraining tool 8 on the other side does not bear acting force; similarly, when a transverse load acts on the other mounting seat 111, the stress conditions of the two transverse stopping restraining tools 8 are opposite.
The invention also provides a loading method of loads of the monorail framework and the axle, which applies any one of the loading devices of the monorail framework and the axle, and comprises the following steps:
s1: a cross member 11 for fixing the base 3 to the frame 1; respectively fixing a travelling wheel tool 4 and a motor substitute tool 5 at two ends of an axle 2 connected with the framework 1;
s2: three-way linear loads are applied to the travelling wheel tool 4 and the motor substitute tool 5 respectively, and/or equal and reverse linear loads are applied to one side of the travelling wheel tool 4.
Before the method is adopted to carry out bench test, the connection between the framework 1 and the axle 2 needs to be ensured according to the connection relation between the actual framework 1 and the actual axle 2, so that the load is transmitted to the framework 1 or the axle 2 according to the real stress condition when the load and/or the torque are applied subsequently.
During operation, the cross beam 11 of the framework 1 is clamped through the base 3, the position freedom degree of the framework 1 is restrained, and the stress condition of the framework 1 is guaranteed. The base 3 is mounted, and the traveling wheel tooling 4 and the motor substitute tooling 5 are connected to both ends of the axle 2.
Next, a three-way linear load and/or torque is applied to the axle 2 by the running wheel tool 4 and the motor substitute tool 5, and the linear load and torque are transmitted to the frame 1 via the axle 2.
During testing, if the detected parameter is a linear load, three-way linear loads are applied to the travelling wheel tool 4 and the motor substitute tool 5 respectively, and the linear loads are transmitted to the axle 2 and the framework 1 through the travelling wheel tool 4 and the motor substitute tool 5.
If the detected parameter is torque, the torque can be applied to the travelling wheel tool 4 or the motor substitute tool 5, and the torque is transmitted to the axle 2 and the framework 1 through the travelling wheel tool 4 or the motor substitute tool 5. According to the actual stress condition of the axle 2, the torque is loaded on the walking wheel tool 4 and is applied to the axle 2 by the walking wheel tool 4.
If the detection parameters comprise linear load and torque, a three-way force load and torque are simultaneously applied to the axle 2 and the framework 1 through the travelling wheel tool 4, and a three-way force load is applied to the axle 2 and the framework 1 through the motor substitute tool 5.
On the basis of the foregoing embodiment, step S2 specifically includes:
s21: the heads of the three first actuators 91 are respectively connected to the travelling wheel tool 4 along the transverse direction, the longitudinal direction and the vertical direction; the heads of the three second actuators 92 are respectively connected to the motor substitute tool 5 along the transverse direction, the longitudinal direction and the vertical direction; fixing the heads of the pair of third actuators 93 to the same side surface of the travelling wheel tooling 4 at intervals;
s22: the applied loads of all the first actuators 91 and all the second actuators 92 are adjusted, and/or the applied loads and/or the pitches of all the third actuators 93 are adjusted.
In the embodiment, in order to adjust the magnitude and direction of the linear load and the magnitude and direction of the torque conveniently, the three first actuators 91 are connected to the end portions of the travelling wheel tooling 4 respectively, and the three first actuators 91 are connected to the travelling wheel tooling 4 along the transverse direction, the longitudinal direction and the vertical direction respectively; two third actuators 93 are connected to the same side of the travelling wheel tooling 4 at intervals and used for applying linear loads with opposite directions to the travelling wheel tooling 4 so as to form a torque acting on the travelling wheel tooling 4; the three second actuators 92 are connected to the end portions of the motor substitute tool 5, and the three second actuators 92 are connected to the motor substitute tool 5 in the transverse direction, the longitudinal direction, and the vertical direction, respectively.
The head of any of the actuators is used for connection and the tail extends out towards the frame 1, avoiding position interference between the frame 1 and the axle 2.
After all the actuators are installed, one or more of the first actuator 91, the second actuator 92 and the third actuator 93 is adjusted according to the test conditions, so as to change the linear load or the torque or the linear load and the torque applied to the axle 2 and the frame 1.
The linear load and the torque are vectors and comprise magnitude and direction, and the magnitude or the direction can be changed only or simultaneously during adjustment.
It should be noted that in the present embodiment, the two third actuators 93 arranged at an interval apply a torque to the axle 2, and the value of the torque applied to the axle 2 is equal to the value of the parallel and opposite loads of the two third actuators 93 multiplied by the value of the moment arm, so that when the torque is adjusted, not only the load of any third actuator 93 but also the distance between the two third actuators 93 can be changed, or the load of the third actuator 93 and the distance between the two third actuators 93 can be adjusted at the same time.
It is noted that, in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.
