The present invention discloses a buckle-type double-opening car barrier and sports car protection device. In the embodiment of the present invention, the locking hook assembly used has only one locking movable component, namely, the locking plate. The movement of the locking plate is a rotation around the pin shaft, which belongs to the low pair, has fewer action links, and the movement form is concise, and the probability of failure is greatly reduced. At the same time, the locking plate is specifically configured to be divided into a first part located on the hook seat side and a second part located on the hook head side by the opening of the pin hole, which is equivalent to a lever as a whole. And the first part shields part of the hook groove in the initial state. When the first part is directly acted upon by the locked component, the locking plate rotates, causing the second part to gradually shield part of the hook groove, thereby reversely constraining the locked component. It is obvious that the action of the locking plate meets the requirement that the greater the pulling force of the locked component, the tighter the locking, and has good locking reliability.
Description
Technical Field
The invention relates to a hasp split type car stop, and also relates to a sports car protection system device with the hasp split type car stop.
Background
According to the regulations of the coal mine safety regulations and the metal nonmetallic mine safety regulations, a car running protection device capable of preventing a running stop rope and unhooked vehicles from being stopped is arranged in an inclined roadway, a car stopper capable of preventing unhooked vehicles from sliding into the inclined roadway is arranged at a position, close to a slope changing point, of an upper flat yard, and a car stopping fence capable of preventing the unhooked vehicles from continuing to run downwards is arranged at a position, which is more than 1 train length, below the slope changing point.
The aforesaid car stop conventionally has net type car stop, bottom lift hasp car stop, hasp split car stop. The net-type car stop is an early car stop and is also the most mature car stop, and the bottom-lifting car stop can be seen in China patent document CN101289091A, however, the car stop needs to be in a storage state when a mine car normally operates, for example, in the patent document, a track needs to be broken, a track bridge is arranged on the car stop, and the car stop is put down in place, namely in the storage state, and is connected with a static track continuously. This structure has been abandoned at present in that, for example, the aforementioned "safety regulations for coal mines" do not allow to break the track.
Also, as in chinese patent CN102806930a, in order to meet the storage requirement of the car stop, it is still necessary to construct notches on the rail, which affect the overall strength of the rail, and to install on the car stop to fill the notches so as to complete the rail filling, the position stability of the rail in the notches depends on the rigidity of the car stop itself, which is often insufficient, thus causing the risk of derailment when the mine car moves to the car stop.
Further, because of some inherent defects of the passing-through type car stop, the production of other types of car stops is accelerated, as an improvement on the bottom-lifting type car stop, the car stop can meet the requirement of protecting a sports car such as a mine car under the condition of not damaging a track, and the Chinese patent document CN110329306A discloses a special self-locking mechanism for the underground car stop, which is essentially a car stop, a left rail body and a right rail body of the underground car stop, wherein the left rail body and the right rail body are respectively connected with a steel wire rope, the steel wire rope is externally connected with an energy absorber, and the two rail bodies can rotate on a vertical shaft, so that the two rail bodies can rotate to a place where the mine car passes, for example, and can rotate to the outer side of the track under the non-protection state without influencing the normal passing of the mine car. Since the impact force of the out-of-control mine car is very large, the mine car cannot be blocked by simply depending on the overhanging fence, and the left and right fences are required to be connected into a whole in the blocking state, and therefore, the self-locking hook is arranged on one fence in the patent document. The self-locking hook comprises a hook main body, wherein an installation positioning hole is formed in the hook main body, guide slide block assemblies are respectively arranged on two sides of the lower end of the hook main body, a self-locking clamp is arranged on each guide slide block assembly, a self-locking clamp connecting groove is formed in each self-locking clamp, the guide slide block assemblies and the self-locking clamp are in sliding connection through the self-locking clamp connecting grooves, a push rod is arranged above the connecting position of the two guide slide block assemblies, and a spring is arranged between the connecting position of the two guide slide block assemblies and the push rod. When the locked part on the other fence body is clamped into the hook main body, the push rod is pressed, and the push rod acts, so that the two guide slide block assemblies act, and the locked part is clamped by the self-locking clamp. Because a plurality of low pairs are adopted, the operation reliability of the low pairs is relatively poor, and the low pairs are extremely easy to cause the blockage of the low pairs, particularly the guide slide block assembly, particularly in the environments with high humidity and high dust in the mine, once the guide slide block assembly is blocked, the push rod occupies part of the lock catch of the hook main body, so that the locking effect of the hook main body is reduced.

Detailed Description
As shown in fig. 1, the roadway rail 5 is generally composed of two rail assemblies, the rail assemblies are formed by sequentially connecting a plurality of rail members, the rail members are generally fixed through rail bolts, the requirement on the integrity of the rail is very high, and rail breakage or slotting on the rail members is not allowed.
The opposite direction of the two track assemblies is generally referred to as inward, and vice versa. And as conventionally understood, the forward and backward directions along the roadway rail 5 are the front and rear directions, and the transverse directions corresponding to the front and rear directions are the left and right directions.
Since the snap-on type car stopper is generally applied to inclined roadways, the roadway bottom surface is used as a reference system, for example, the left swing frame and the right swing frame 41 are approximately vertical to the roadway floor.
In some embodiments, however, left and right swing frames 41 may be maintained at a set angle to the roadway floor, typically with respect to a perpendicular to the roadway floor, which is a skew angle relative to the reference, typically not greater than 15 degrees.
As can be seen in the configuration shown in fig. 1, for a snap-on truck bed, for example, the left upright 20 for mounting the left swing frame and the right upright 14 for mounting the right swing frame 41, the spacing between the uprights is sufficient to allow the passage of the mine car, while the width of the mine car is generally greater than the width, or gauge, between the track assemblies. For the left swing frame and the right swing frame 41, when the mine car normally operates, the two swing frames should not prevent the normal operation of the mine car, and at the moment, the two swing frames need to be separated and swing out of the operation path of the mine car. If a car accident occurs, the two swing frames need to swing to the upper side of the roadway rail 5 and are connected to play a role in blocking, so that the lock hook assembly for connecting the two swing frames is required to be connected reliably, and as an extension, the lock hook assembly is required to act smoothly, otherwise, the connection reliability cannot be guaranteed. This is a technical requirement for the shackle assembly.
In the following, according to the technical requirements of the latch hook assembly in the foregoing, a specific description of the snap-on type vehicle barrier is expanded, and it should be noted that, in the embodiment of the present invention, the snap-on type vehicle barrier is described by way of illustration, and a simple replacement of the adopted technical means should fall into the protection scope of the present invention. Meanwhile, the terminology used is not limited in its structure unless specifically stated.
The car stop bar necessarily comprises a frame body, wherein the frame body is an installation base body of other car stop functional components, and the frame body is generally and fixedly installed on the ground or the side wall of a roadway, and is generally installed on the ground.
To ensure reliability of installation, it is often necessary to form the cement-based foundation 1 on the ground by casting, and in some embodiments, the frame may be partially built into the foundation 1, but such a structure is disadvantageous for maintenance of the apparatus, and thus, in the structure shown in fig. 1 and 3, the frame is installed by the anchor bolts 2, and the anchor bolts 2 are embedded into the foundation 1.
In some embodiments, in order to ensure positional accuracy of the anchor bolts 2, the anchor bolts 2 may be pre-installed on, for example, an anchor plate, with the distribution of the anchor bolts 2 being constrained by pre-opened bolt holes on the anchor plate with relatively high positional accuracy.
Furthermore, the presence of the anchor plate may also improve the reliability of the fixation of the foundation bolt 2 as a basis 1.
The anchor plate may in some embodiments also be constructed as a frame structure with bolt holes pre-opened in some beams of the frame or with anchor bolts 2 welded directly to the frame structure.
It will be appreciated that the frame body must contain a portion located outside the roadway rail 5, otherwise the mounting structure of the car stop would affect the passage of the mine car. It is particularly noted that in the embodiments of the present invention, the stopper has a degree of freedom of rotation based on rotation, and is in a blocking state after being rotated above the roadway rail 5 and the two stoppers are connected to each other, and a closing state mentioned below. When the mine car rotates to the outer side of the roadway rail 5, and after the passing path of the mine car is completely avoided, the mine car is in an open state, namely a split state is mentioned below.
The rotation depends on Zuo Baijia and the right swing frame 41 should have a degree of freedom of rotation, and based on the foregoing description, it is understood that the rotation axes of the left swing frame and the right swing frame 41 adapted to rotate may be perpendicular to the roadway floor or may be at a relatively small angle, which is usually not greater than 15 degrees, and will be exemplified below perpendicular to the roadway floor. When the left and right swing frames 41 are rotated to the blocking position, i.e., in the aforementioned blocking state, the two swing frames and the roadway rail 5 exhibit the state shown in fig. 1, i.e., are perpendicular to the roadway rail 5.
The adapted shafts, i.e. the left shaft 4 and the right shaft 12 shown in fig. 1, are perpendicular to the roadway rail 5 in fig. 1, but may also have a certain inclination.
As can be seen from the figure, the left rotating shaft 4 is located at the left side of the left rail assembly, and the right rotating shaft 12 is located at the right side of the right rail assembly, i.e. the normal running path of the mine car is avoided.
For the movements of the left and right carriages 41, which are among the most common rotations in the mechanical field, rotation is one of the most easily available forms of movement in the mechanical field, the implementation is relatively simple. In the embodiment of the present invention, the driving mechanism for driving the left swing frame and the right swing frame 41 to move is referred to as a driving assembly, so as to drive the two swing frames to be folded or folded.
Compared with the prior art, the invention focuses on improving the lock hook assembly 9 to ensure that the lock hook assembly is locked reliably and acts smoothly.
Specifically, with respect to the latch hook assembly 9, it is mounted on the left swing frame or the right swing frame 41, i.e., one of the two swing frames, and then the other swing frame is locked. After the mine car is impacted onto the car stop, the car stop falls off from the frame body, typically, the rotating shaft is broken, the steel wire rope connected to the two swing frames plays a traction role, and the steel wire rope is connected with the energy absorber to gradually consume energy, so that the kinetic energy of the mine car is gradually reduced.
The kinetic energy of the mine car when initially contacting the car stop is relatively large, which requires that the car stop be kept intact, and if the connection between the two carriages is broken, the mine car can continue to run down and lose the protective effect of the running car.
In view of this, specifically, in the structure shown in fig. 4, the latch hook assembly 9 includes a hook body 43 having a hook head and a hook seat, in which the portion where the fitting hole 46 is opened is the hook seat of the hook body 9, and the portion where the left loop is formed to define the hook groove is a functional portion of the hook body, and the end of the portion is the hook head, which generally has a relatively gentle contour, generally has a guide surface, and has a function of facilitating the introduction of the functional target of the hook.
In fig. 4, the right tube 10 is a target to which the hook body 43 is hooked, and a direction perpendicular to the paper surface in the drawing is generally a direction defining a hook side surface, and is generally referred to as a left side and a right side of the hook body 43. In the structure shown in fig. 4 and 5, there are two lock plates 44, the lock plates 44 are rotatably installed at the middle side of the hook body 43 by means of the pin shaft 42, the lock plates 44 have a degree of freedom of rotation, the initial position of the lock plates 44 can be defined by the structure, and in the structure shown in fig. 1, the position of the lock plates 44 is determined by the tension spring 45.
The tension spring 45 is also referred to as a tension spring, and in its fully retracted state, has no axial compression, so that the initial rotational angle of the lock plate 44 can be determined.
In addition, in order to ensure the relative stability of the initial position of the lock plate 44, the tension spring 45 should have a certain pre-stretching amount, and a stop pin may be disposed on the hook body to stop the lock plate 44 from further rotating counterclockwise in fig. 4 under the tension of the tension spring 45, so that the lock plate 44 can have a tension force at this time, and a stable initial state can be maintained.
Further, in the structure shown in fig. 4, the locked member is a right guard tube 10 shown in the drawing, and accordingly, the latch hook assembly 9 is mounted on the left swing frame. The right guard tube 10 constitutes the locking object of the locking hook assembly 9, called the locked member.
The locked member may be a right protection tube 10 which is independently provided as shown in fig. 4, or may be a locked member which is included in the latch hook assembly 9, for example, a hanging ring which is welded to the right swing frame 41 and can be hooked by the lock body 43.
When the locked member is introduced into the hook groove of the hook body 43, the force applied to the hook body 43 by the locked member is biased to the side of the hook seat at the pin setting position, in other words, when the locked member is inserted into the groove, it is pressed to the right of the pin 42 in fig. 4.
Accordingly, the locking plate 44 is divided into a first portion located at the hook side and a second portion located at the hook side by the opened pin hole, and the lever is integrally formed with the pin shaft 42 as a fixed hinge support, so that when the first portion receives downward pressure as shown in fig. 4, the locking plate 44 rotates clockwise, and the tension spring 45 provides a counter moment, and the first portion is far from the groove and the second portion is close to the groove, thereby achieving locking.
Specifically, the first portion shields part of the hook groove in the initial state, and is driven away when it is pressed, so that the locked member is finally supported on the hook body 43, and the lock plate 44 stops rotating. In this process, as described above, the second portion gradually covers part of the groove during clockwise rotation, and the locked member is covered by the contour, as shown in fig. 4, the direction of the right tube 10 is covered, and the greater the pulling force of the hook body 43, the stronger the backstop of the second portion.
It will be appreciated that the second portion must be able to avoid the locked member in position when in the initial state, and thus be able to constrain the locked member in a reverse direction when it is in abutment against the bottom of the hooking recess, and, based on this principle, the person skilled in the art can set the general structure of the locking plate 44 without any inventive effort. In particular, the two swing frames are locked by the hook body 43, and the locking plate 44 only plays an auxiliary role, so that the locking state is prevented from being released in the blocking process, and the strength requirement is not high.
In the structure shown in fig. 5, the locking plates 44 are two, and two locking plates 44 are arranged on two sides corresponding to the hook body 43, so that locking force can be more balanced.
In the foregoing, in order to maintain the lock plate 44 in a good initial state, it is provided with a tension spring 45, specifically, one end of the tension spring 45 is connected to the first portion, and the other end is mounted on the side of the hook body 43 where the hook head of the pin shaft 42 is disposed, so as to provide a counter torque, and accordingly, the moment generated by the locked member acting on the lock plate is a positive moment.
Since the force of the locked member pressing the locking plate 44 can maintain the locking plate in a stable state after the locked member is inserted into the hook groove, in other words, only the initial state of the locking plate 44 can be maintained, in some embodiments, the pair of rotation pins 42 can use a damping pair, in other words, a certain force is required to rotate the locking plate 44, and the force can maintain the state of the locking plate 44 under the condition of no external force.
While in other embodiments, the lock plate 44 may be locked in its initial state using, for example, a shear pin, the shear force of which need not be too great, but rather merely maintain the lock plate 44 in its initial state.
It will be apparent that it is also possible to bind the second part with an article having a certain binding force, such as cotton threads, which provides a low position maintaining force.
With respect to the locking plate 44, as shown in FIG. 4, the locking plate 44 is shown as a curved plate with curved slots and the notches have an introduction arc to facilitate introduction of the right tube 10, for example.
Accordingly, in the initial state, the notch of the lock plate 44 guides the locked member together with the notch of the hook body 43.
To ensure the reliability of the locking, two, but not limited to two, locking hook assemblies 9 are shown in fig. 1, and more may be provided if necessary, but generally not more than four, preferably two.
When there are a plurality of the latch hook assemblies 9, the plurality of latch hook assemblies 9 are distributed in the height direction of the check rail.
In the structure shown in fig. 1, the left and right protective pipes 6 and 10 are used to thread steel ropes, such as the left and right ropes 7 and 13 shown in fig. 1, so that the right rope 13 must be hooked by the latch hook while the right protective pipe 10 is hooked by the latch hook in the structure shown in fig. 4. The purpose of this arrangement is that, although the strength of the protective tube itself is high, it is easily broken, and the wire rope has a certain toughness and is not easily broken. For example, even if a protective tube is not used, a wire rope should be included with the hook body 43.
It should be appreciated that in the field of car barriers, the wire rope is necessarily required to be connected to an energy absorber, which is also described in the foregoing.
Relatively, the tube body is easier to set, if a rod is used instead of the protective tube, the wire rope needs to be parallel to the rod, and the volume of the hook body 43 tends to be increased.
In the structure shown in fig. 1, the tube body is a U-shaped tube, the plane defined by the axis of the U-shaped tube is parallel to the blocking plane defined by the left swing frame or the right swing frame 41, and the connecting arc tube of the U-shaped tube for connecting the two straight tube portions is locked by the locking hook assembly 9.
In the structure shown in fig. 1 to 3, the frame body includes:
a base 15 which is installed at the lower side of the tunnel rail 5 and has base portions located at the left and right outer sides of the tunnel rail 9, and the description of the frame portions in the foregoing is referred to with respect to the installation manner of the base 15.
The stand column is arranged on the base, and correspondingly, the rotating shaft is arranged on the stand column.
In the preferred embodiment, the rotation shaft is contained in the side hinges, and the left swing frame and the right swing frame 41 are respectively adapted with two side hinges, which can be seen in the structure shown in fig. 3, and the common side hinges are hinges, which have relatively low connection strength, are easy to fall off when receiving an impact, and meet the requirement of using the car stop.
The rocker on the car stop cannot be reused after being impacted, but can still be reused, for example, the upright, the base 15 and the like, for which reason the damage to the upright is small after the rocker is detached from the upright by impact, for which purpose the upright is fitted with a diagonal strut 40, the diagonal strut 40 being arranged on the high side of the upright mounting position. It should be noted that, for the sports car protection device, the sports car protection device is generally arranged on an inclined roadway, and the high position of the sports car protection device is the position in the inclined roadway, where the sports car protection device is installed, which is relatively high.
As can be seen from fig. 2, the base 15 is a rectangular frame provided with at least longitudinal beams, so as to have a reliable structure, while in some embodiments it may also be provided with transverse beams.
Correspondingly, the stringers are beams along the roadway rail 5.
With respect to drive assemblies, as snap-on side-by-side vehicle barriers have become relatively mature, mechanisms for achieving side-by-side are also relatively mature, particularly across areas, and side-by-side doors controlled by mechanisms have long become a common form of machinery.
In an embodiment of the invention, two drive assemblies are preferred, one being a triangle mechanism and the other being a link mechanism, wherein the triangle mechanism essentially belongs to a variant of the link mechanism, also being a link mechanism in nature.
Further, if the mechanism is a triangle mechanism, a power machine is respectively arranged for the left swing frame and the right swing frame.
If the left swing frame and the right swing frame are of a connecting rod mechanism, the left swing frame and the right swing frame share one power machine.
In some embodiments, the power machine of the triangle mechanism is a hydraulic cylinder, the hydraulic cylinder is configured on one side of the triangle mechanism, and the push rod of the hydraulic cylinder is hinged on the left swing frame or the right swing frame 41, and the left swing frame or the right swing frame 41 forms one side. The triangle mechanism belongs to a common mechanism in the mechanical field and is not described in detail here.
In some embodiments, referring to fig. 2 of the specification, the linkage includes:
