Description
Technical Field
The invention relates to a push head assembly, a trolley section provided with the push head assembly and a trolley machine comprising the trolley section, wherein the push head is also called a push claw or a push claw.
Background
The car pusher for mine is mainly used for transporting vehicles such as mine shafts or underground yards for dispatching mine cars, flat cars, material cars and the like and auxiliary materials thereof. However, the application of the mining car pusher is not limited to a coal mine wellhead or a shaft bottom yard, and the mining car pusher can be also used for dispatching and transporting operations of transportation yards such as a metallurgical mine yard, a nonmetal mine yard, an engineering building yard (such as a tunnel) and the like.
Fig. 1 shows a conventional cart section for a cart machine, which comprises a cart body 1 and a pushing head 2 mounted on the cart body 1 through a spindle 3, wherein the pushing head 2 forms an oscillating arm based on the spindle 3, and a lower limit plate and an upper limit plate are arranged on the cart body 1 to restrict the rotation angle range of the pushing head 2. One end of the pushing head 2 is a working end, the other end is hinged with a compression spring set 4 (the compression spring set 4 is a spring guide pillar and hinged with the guide pillar), the pushing head 2 is in a state shown in fig. 1 based on the elasticity of the compression spring set 4, when a mine car moves from the right side to the left side in the figure, for example, the pushing head 2 is firstly pressed down, the compression spring set 4 is compressed, after the mine car surpasses the pushing head 2, the pushing head 2 is reset, the working end reversely presses the mine car, and then the car pusher can push the car by means of the pressing relation between the pushing plate 2 and the mine car. When the mine car needs to be withdrawn, the push head 2 needs to be manually pressed down to ensure that the push head 2 does not obstruct the mine car from being withdrawn, in other words, the working mode of the push head 2 is passive, the working efficiency of the mine car is affected due to the need of manual intervention, and the injury or other risks are inevitably increased due to the manual intervention.
In view of this, for example, chinese patent document CN 108639919A discloses a bidirectional cart for single-ended access to a mine car and a bidirectional cart method, wherein the cart section includes cart claws (i.e., pushing heads), and an automatic lifting device for driving the cart claws to lift and fall, the so-called automatic lifting device realizes the automatic lifting and falling of the cart claws, thereby avoiding the risk that may be faced when the cart claws are manually operated. In this patent document, an automatic landing gear for realizing landing of the cart claw is located below the cart section and is arranged separately from the cart section, and the automatic landing gear can only function when the cart section is operated to a specific position, so that landing of the cart claw is realized based on cooperation with a landing block in the automatic landing gear. In this process, the operating accuracy of the trolley segments is required to be relatively high, in particular, in the axial direction of the wheel axis of the trolley segments. Likewise, the accuracy of operation of e.g. a mine car will be relatively high, in that the trolley claw will only be turned up when the trolley is operated to a specific position, whereby the parking position of the mine car is required to be adapted to the pushing of the trolley claw, and when the trolley is moved away from this position, the trolley claw will fall down without reaction of the mine car, thus increasing the control difficulty as a whole.

Detailed Description
As for the cart section, it should be understood that, in accordance with the general reference frame of the vehicle, the direction along the cart section is generally referred to as the longitudinal direction, and the direction perpendicular to the longitudinal direction in the plane of the frame (the cart body 1 in fig. 3 includes the frame) is the transverse direction, and the direction perpendicular to the plane of the frame is the vertical direction.
Furthermore, for a cart section, there are defined front and rear, corresponding to the head and tail of the cart section.
Correspondingly, in the trolley state, the direction of the pushing force provided by the pushing head is forward, and conversely, backward.
It should be noted that, in the structure illustrated in fig. 2, the current state of the push head 2 is also the normal state of the push head 2, which theoretically belongs to the reset state, but in the embodiment of the present invention, for convenience of description, the normal state is referred to as the operation state of the push head 2, and a process of pushing the driving end of the push head 2 by the electric push rod 8 to disengage the push head 2 from the operation state is referred to as reset, and the final reset state is referred to as the reset state.
Fig. 2 to 4 illustrate a cart section structure, in which a connecting pin 11 is disposed at the left end of a cart body 1 in fig. 3, and a flat washer 12 and a cotter pin 13 are matched and connected with corresponding connecting pin holes 15 on other cart sections. The car section is a car section of a car pusher, and a car pusher includes but is not limited to a car section.
Correspondingly, the connecting pin shaft holes 15 in fig. 3 are used for the mating connection with corresponding connecting pins 11 on other vehicle segments.
The push head assembly illustrated in fig. 2-4 is mounted on a frame of a cart section, the frame is represented as a cart body 1 in fig. 1, the push head assembly comprises a lever type structure composed of a push head 2 and a mandrel 3, the constraint comprises a limiting plate 5 and a limiting block 9, and an electric push rod 8 provided with a wedge block 7, wherein the constraint is used for limiting the corner range of the lever type structure, the electric push rod 8 provided with the wedge block 7 is used for resetting the push head 2, and the state of the push head 2 shown in fig. 2 is a normal state, namely a working state.
Generally in the mechanical field, the relatively stationary base portion to which the movable member is mounted may be referred to as a frame, and in the structure illustrated in fig. 2, the vehicle body 1 may constitute a base of a lever type structure.
Correspondingly, the spindle 3 is transversely arranged on the vehicle body 1, the spindle 3 and the vehicle body 1 can be fixedly connected, or can be rotatably connected, for example, the spindle 3 is arranged on the vehicle body 1 through a bearing, if the spindle 3 can rotate, the push head 2 and the spindle 3 are fixedly connected, if the spindle 3 is fixedly arranged, the spindle 3 and the push head 2 are configured to be in rotary fit, for example, the push head 2 is arranged on the spindle 3 through the bearing.
It should be noted that in the mechanical field, the spindle 3 does not necessarily represent a shaft which can move, but rather a shaft which is subjected to only bending moments, as distinguished from a rotating shaft (which only transmits torque) and a drive shaft (which is subjected to both bending moments and transmits torque).
The push head 2 has a degree of freedom of rotation about the axis of the spindle 3 by means of the cooperation between the spindle 3 and the push head 2, and with the body 1, whereas as previously mentioned, the range of rotation of the push head 2 is not limited by the constraint, so that the form of movement of the push head 2 is oscillatory.
The swing necessarily corresponds to two boundary dead points, namely to the operating dynamics of fig. 2 and the reset state shown in fig. 9.
In the foregoing, the spindle 3 is directly connected to the vehicle body 1, and in most applications, the spindle 3 is mounted to the vehicle body 1 by means of, for example, a fixed hinge support, which may be, for example, a split bearing block or a simple fixed seat.
Based on the reference frame of the vehicle body 1, the push head 2 is also adapted to have a transverse direction and a longitudinal direction, and accordingly, the push head 2 needs to be provided with a transverse spindle hole 23, and the position of the spindle hole 23 can be seen more clearly in fig. 5, and in the longitudinal direction, the spindle hole 23 is offset to the lower end in fig. 5, instead of being centrally arranged, so as to reduce the working stroke of the electric push rod 8, for example.
In the longitudinal direction of the push head 2, one end is a working end, and the other end is a driving end, and accordingly, the driving end is opposite to the working end, but from the aspect of the length relationship of the lever sections, the lever section of the driven end (working end) of the lever type structure is relatively longer. Accordingly, the foregoing offset, described in terms of the driving end and the working end, is represented by the spindle hole 23 being offset toward the driving end side.
In view of the fact that, for example, the electric push rod 8 is the active device and, for example, the mine car is the device pushed by the pusher head 2, the driving end is the end into which the power is introduced and the end into which the restoring force is introduced. The working end is the end for the cart, i.e. the end applying force to the outside.
In view of the relatively large reaction forces of e.g. a car when pushed, it is preferable that the portion of the aforementioned constraint that keeps the pusher head 2 in the working position is a rigid constraint, such as the limiting plate 5 shown in fig. 2, the limiting plate 5 is a steel plate, and the limiting plate 5 can be welded to the car body 1 in a welded manner to improve the reliability of the limitation.
In view of the operational state of conventional pushers, springs are commonly used to maintain the relative stationarity of the operational state, but springs have inherent drawbacks such as being prone to fatigue fracture or accidental jamming that can interfere with the proper use of the pusher assembly. The force to maintain the working condition is thus achieved in the preferred embodiment by means of gravity, in the configuration illustrated in fig. 5 and 6 the push head portion on the underside of the spindle 3 being provided with a set of support plates 28, the presence of the set of support plates 28 being such that the weight of the portion is relatively large despite the relatively short length, whilst in the configuration illustrated in fig. 7 the set of support plates 28 is again provided with a counterweight, whereby the working condition of the push head 2 is maintained relatively stable.
In fig. 7, in order to fully utilize the space under the push head 2, the balancing weights further include a lower balancing weight 282 and an upper balancing weight 283 that are accommodated in the space under the upper panel 21.
By means of the weight of the support plate package 28, rather than the external spring force, no damage or unsmooth attachment (spring) is produced, and thus better reliability, while ensuring that the pusher 2 remains in the operating position.
And the support plate set 28 may also be arranged centrally (laterally) from side to side in a space, for example below the upper panel 21, for access to the drive mechanism.
Accordingly, the driving mechanism is directly or indirectly arranged on the frame instead of being arranged outside the car puller, so that the relative accuracy of driving is improved, and the driving mechanism is not limited by the stop position of the car puller.
Further, the output member of the driving mechanism is located below the spindle 3 and has a degree of freedom of linear movement, which is a degree of freedom in the longitudinal direction of the vehicle body 1 or in a direction having an angle of not more than 15 degrees with the longitudinal direction of the vehicle body 1, which is an angle with respect to the lower side of the frame plane, to push the driving end to return the push head 2. The former is preferable in that the degree of freedom of linear motion is the degree of freedom in the longitudinal direction of the vehicle body 1, so that the utilization ratio of the assembly space of the drive mechanism is relatively good. While in the latter case, it is more advantageous to obtain a greater resetting force for resetting the push head 2.
However, since the weight of the pusher 2 is relatively small and the restoring force is not required to be high, it is preferable that the output member of the drive mechanism is arranged to move in the longitudinal direction of the vehicle body 1.
As a relatively compact arrangement, the drive mechanism is a fluid cylinder or electric push rod 8, both of which are relatively compact in overall construction and generally feature a rod member for easy placement in the direction of the vehicle body 1.
The hydraulic cylinder mainly comprises a cylinder and a hydraulic cylinder, the response speed of the cylinder is high, the power density of the hydraulic cylinder is high, and the operation is stable.
Accordingly, for a fluid cylinder, its output member is typically its push rod (also known as a piston rod).
For the electric push rod, which is a finished product, the output member is also a rod, also commonly referred to as a push rod, the structural form of which can be seen in fig. 8, and thus the push rod as a whole constitutes the output member of the driving mechanism.
And an electric push rod, wherein the push rod of the electric push rod forms the output component.
As previously mentioned, in view of the relatively compact construction that is readily available when the drive mechanism is arranged longitudinally along the vehicle body 1, the push rod is arranged longitudinally along the vehicle body, the seat end of the respective fluid cylinder or electric push rod 8 being fixed to the frame.
Regarding the introduction of the source end, the car pusher can be provided with a source end, such as a battery compartment, and particularly, the battery pack 18 illustrated in fig. 4 can be seen, in that the frequency of opening and closing the push head 2 is not high, a heat engine is relatively inadaptable, the heat engine is started slowly, and the energy consumption of opening and closing each time is high.
For the car pusher, an external power source may be introduced, and both ends of the car body 1 as shown in fig. 4 are provided with cable interfaces to access the external power source.
As can be seen in fig. 2, a wedge block 7 is mounted on the push rod of the electric push rod 8, and the wedge block 7 is engaged with the driving end to form a wedge mechanism so as to push the push head to reset from the working position. The cam mechanism is very similar in some respects to the cam mechanism in that the desired complex pattern of motion is readily obtained.
In the embodiment of the present invention, the cam mechanism first converts the horizontal movement into the swing of the push head 2.
In view of the fact that the wedge mechanism is relatively harsh in the same manner as the cam mechanism, in the preferred embodiment, the driving end is provided with the roller 6 at the position matched with the wedge block 7, so that the wedge pair of the wedge mechanism forms a rolling friction pair, thereby improving the stress environment of the wedge mechanism.
Referring to the structure shown in fig. 5 and 6, the pusher 2 is in a plate-and-frame structure, and can have relatively high rigidity under the condition of relatively small overall weight, and in the structure illustrated in fig. 5 and 6, the pusher 2 has an upper panel 21, and two lateral sides are respectively provided with a side plate 24, and welding is preferable between the upper panel 21 and the side plate 24.
The lower edge of the side plate 24 is a horizontal edge, the right side edge is a vertical edge in the structure illustrated in fig. 5, the state illustrated in fig. 5 is the working state of the push head 2, a push plate 27 is welded at the vertical edge of the side plate 24, and the push plate directly contacts with a mine car for example to apply thrust.
The push plate 27 is also welded to the upper edge of the upper panel 21 to increase the overall rigidity.
A reinforcing plate 26 is welded to the back side of the push plate 27, and if a horizontal plate as shown in fig. 5 is used as the reinforcing plate 26, the reinforcing plate is welded to both the upper panel 21 and the side plate 21.
The push plate 27 forms an angle with the upper panel 21, and a triangular zone is defined, in which triangular zone a number of triangular stiffening plates 26 can be arranged, the stiffening plates 26 forming risers while being welded with the upper panel 21 and the push plate 27.
The upper panel 21 may be reinforced, and an upper reinforcing plate for reinforcing the upper panel 21 may be provided in parallel with the side plates 24, and welded to the upper panel 21.
In the foregoing, it is noted that in the structure illustrated in fig. 5, the lower edge of the side plate is a horizontal edge when the pusher 2 is in the working state, and the lower edge of the pusher 2 is correspondingly trimmed to provide an integral supported edge, thereby providing a limiting plate 5 as shown in fig. 2, and providing support for the supported edge.
The limiting plate 5 is fixedly arranged on the frame, and a welding mode is preferably adopted between the limiting plate 5 and the frame.
Correspondingly, the supported rim is just engaged with the limiting plate 5 when the push head 2 is in the working state.
In fig. 2, the push head 2 is in an operating state, supported by the support edge on the limiting plate 5, and when the push head 2 is reset, the push head rotates clockwise to a state shown in fig. 9, and at this time, the push plate 27 is supported on the limiting block 9 to be limited. At this time, the stopper 9 constitutes a reset stop constraint.
In fig. 2, the limiting block 9 is a trapezoid block, in the figure, an isosceles trapezoid block is fixed on the frame through a screw, and the push plate 27 in a vertical state in a working state becomes an inclined plate after rotating clockwise for a given angle, and is just matched with one waist of the trapezoid block, so that reliable supporting performance is obtained.
