Description

Technical Field

[0001] The invention relates to the field of automobile exhaust gas detection equipment, and more specifically, to a track mechanism and a gas introduction device having the track mechanism. Background Art

[0002] In order to meet the requirements of automobile exhaust emission regulations, exhaust emission tests are required before the product vehicles leave the factory. The AVL GAS1000 exhaust gas analyzer is equipped with a purification unit. The exhaust gas probe is used to collect exhaust gas from the automobile exhaust pipe. The purification unit is connected to the compressed air air pipe to blow out the residual moisture in the exhaust gas probe regularly to prevent the accumulation of moisture from affecting the test results. In terms of the introduction of compressed air to the purification unit, the current technical solution is as follows: the compressed air from the fixed air source point is connected to the compressed air introduction interface of the purification unit through the PU air pipe. This solution is suitable for occasions where the equipment is fixed, but cannot meet the occasions where the purification unit box is mobile, and cannot be automated. In order to meet the exhaust gas accompanying detection process (that is, the exhaust gas emission station of the product vehicle uses the synchronous operation of the friction conveyor line and the rain conveyor line to realize follow-up detection, and the trolley on the friction line is equipped with a wireless exhaust gas detection device), a new type of auxiliary device must be introduced to introduce compressed air to the exhaust gas equipment carried by the friction conveyor equipment. Summary of the invention

[0003] In order to overcome the problem that the current technical solution described in the above background technology is only applicable to occasions where the equipment is fixed, cannot meet the needs of occasions where the purification unit box on the friction line is movable, and cannot achieve automation, the present invention provides a track mechanism and a gas introduction device having the track mechanism.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a track mechanism, including a base and a reset device, at least two guide rails, a collision rail, and a dislocation rail are arranged above the base, one end of the reset device is connected to one end of the base, the guide rails, the collision rails and the dislocation rails are parallel to each other, the collision rail is provided with a first collision block of a trapezoidal structure, and the dislocation rail is provided with a dislocation block of a trapezoidal structure. In this way, it is equivalent to having at least four parallel tracks on a base for different mechanism functions, and setting up a trapezoidal first collision block on the collision rail can make the wheels have an uphill and a downhill process when running on it, changing the running state of the wheels, and used in some special devices. Similarly, the dislocation block can also play this role, and the guide rail can be used for the guided sliding of an integral sliding mechanism above.

[0005] Furthermore, the number of the guide rails is 2, the dislocation rail is located between the two parallel guide rails, and the impact rail is located outside the two guide rails. In this way, when the number of the guide rails is 2, the function of guiding sliding can be achieved, and the structure is the simplest, the dislocation rail is in the middle, and the impact rail is on the outside, which can be more reasonable in layout.

[0006] Furthermore, the dislocation block is a right-angled trapezoidal structure, the lower base of the dislocation block is fixedly attached to the dislocation rail, and the hypotenuse of the dislocation block is located at one end of the dislocation block close to the first impact block. In this way, the dislocation block and the first impact block do not correspond to the same position on the guide rail, and on the guide rail travel, the first impact block is passed first, and then the dislocation block is passed, and both the first impact block and the dislocation block first undergo an uphill process to change the movement state.

[0007] Further, a limiting projection is provided on the upper bottom of the dislocation block near one end of the straight waist of the dislocation block. In this way, the function of the limiting projection is to prevent the sliding mechanism from overtravel, so that the sliding mechanism will not move forward and disengage from the dislocation block after completing the change of motion state after going uphill.

[0008] A gas introduction device is also provided, comprising a mounting plate, a sliding mechanism and the above-mentioned track mechanism which are arranged in sequence;

[0009] The mounting plate is provided with an air connection structure and a positioning push block;

[0010] The sliding mechanism includes a frame, on which a movable rod, a first cylinder, an air intake structure capable of aligning with the air receiving structure, and a first mechanical roller valve that controls the common air path of the first cylinder and the air intake structure are provided. The air intake structure is connected to the piston rod of the first cylinder, and the frame is connected to the guide rail and can move on the guide rail. The movable rod is connected to the frame through a rotating shaft, and the movable rod can rotate around the rotating shaft. A protrusion is fixedly connected to one end of the movable rod, and the protrusion can be contacted and connected with the positioning push block. A roller rod is connected to the other end of the movable rod, and a roller used in conjunction with the dislocation rail is provided at one end of the roller rod away from the movable rod; the first mechanical roller valve is located at the bottom of the frame and can move on the impact rail, and the other end of the reset device is fixedly connected to the frame. In this way, on the basis of setting up the above-mentioned track mechanism, the sliding mechanism changes its motion state by cooperating with the track mechanism to achieve the control of gas introduction, and its entire operation process is very clever. First, the mounting plate is used to install the purification unit, and an air connection structure is arranged on the plate, and the air connection structure is connected with the purification unit. This belongs to the prior art and does not need to be described in detail. The mounting plate carries the purification unit as a whole and moves on the friction line above. A track mechanism and a sliding mechanism are arranged below a certain point of the friction line to cooperate with the mounting plate. When the mounting plate runs to the sliding mechanism, the positioning push block under the mounting plate is connected to the protrusion on the movable rod, and the protrusion is in a state perpendicular to the horizontal plane. The protrusion is preferably perpendicular to the movable rod, and the movable rod is in a horizontal position. The roller rod is also perpendicular to the movable rod, and the roller rod contacts the dislocation rail through the roller at the other end of the movable rod downward; the positioning push block is stuck by the vertical protrusion, and when the mounting plate continues to move forward under the action of power, it can pass through the fixed The push block pushes the sliding mechanism below to move on the track mechanism, and a first mechanical roller valve is arranged below one side of the sliding mechanism frame, and the first mechanical roller valve moves forward on the impact rail. When the first mechanical roller valve moves to the first impact block and rolls onto the slope of one side of the trapezoidal first impact block, it can open the common passage between the first cylinder and the air intake structure. The first cylinder is arranged vertically on a horizontal plane, and the piston rod of the first cylinder faces the air receiving structure, and the air outlet pipe of the air intake structure fixedly arranged on the rod head of the piston rod also faces the air receiving structure. When the piston rod of the first cylinder extends upward, the air intake structure introduces gas to the air receiving structure. The connection position between the air intake structure and the air receiving structure is made of rubber material, which has a certain sealing performance, and when the air intake structure and the air receiving structure are in place, the power device control mounting plate stays at this position for a period of time, and the piston rod no longer extends upward to ensure the safety of the device. This can be achieved by setting the specific position of the first cylinder or setting a corresponding sensor.Afterwards, when the air intake structure and the air receiving structure have completed the gas introduction, the power device continues to drive the mounting plate forward along the friction line. At this time, the first mechanical roller valve goes down the slope, the corresponding air path is closed, and the cylinder piston rod retracts; the roller on the roller rod continues to move on the dislocation rail, and then moves to the dislocation block. Since the movable rod and the frame are hinged, when the roller goes up the slope of the dislocation block, the roller rod can make the movable rod rotate, and the rotation of the movable rod also moves with the protrusion. The protrusion disengages from the positioning push block, and the mounting plate no longer pushes the sliding mechanism forward, completing the installation. The dislocation of the mounting plate and the sliding mechanism; in addition, since a reset device is also provided on the track mechanism, the reset device is generally arranged under the guide rail, one end of the reset device is connected to the track mechanism, and the other end is connected to the sliding mechanism. The track mechanism is fixed on the ground, so when the sliding mechanism is pushed to move on the track mechanism, the reset device is also compressed or stretched at the same time. When the sliding mechanism is dislocated from the mounting plate, the reset device brings the sliding mechanism back to the initial position to prepare for the next gas introduction. This reciprocating process can realize the automation and programming of gas introduction and improve production efficiency.

[0011] As another preferred solution, the reset device is a second cylinder, the cylinder body of the second cylinder is fixed on the base, the piston rod head of the second cylinder is fixedly connected to the connecting plate at the bottom of the frame, the mounting plate is provided with a second impact block of a trapezoidal structure, the top of the frame is provided with a second mechanical roller valve for controlling the gas path of the second cylinder, the second mechanical roller valve can move on the second impact block, and the piston rod of the cylinder is parallel to the guide rail. In this way, the reset device in this solution is a second cylinder, and the second mechanical roller valve is located at the top, which is more reasonable in structural design and makes the setting simpler. When the positioning push block of the mounting plate contacts the convex block of the sliding mechanism, the second mechanical roller valve moves onto the second impact block, so that the gas path of the second cylinder is closed, the piston rod is no longer subjected to the pressure of the gas in the cylinder barrel, and the sliding mechanism compresses the piston rod back into the cylinder barrel of the cylinder. When the mounting plate is dislocated from the sliding mechanism, the second mechanical roller valve is no longer affected by the second impact block, the gas path of the second cylinder is opened, the cylinder is inlet, the piston rod is pushed out, and the sliding mechanism is driven back to the initial position to wait for the next gas introduction process.

[0012] As a preferred solution, the resetting device is a second cylinder, the cylinder body of the second cylinder is fixed on the base, the piston rod head of the second cylinder is fixedly connected to the connecting plate at the bottom of the frame, and the bottom of the frame is also provided with a second mechanical roller valve for controlling the air circuit of the second cylinder, the first mechanical roller valve and the second mechanical roller valve can both move on the impact rail, and the second mechanical roller valve is located between the first mechanical roller valve and the first impact block. In this way, the reset device adopted in this scheme mainly includes a second cylinder, and the gas pipeline assembly of the second cylinder is installed with the second mechanical roller valve. The gas passage of the second cylinder is controlled by the second mechanical roller valve. When the second mechanical roller valve contacts the first impact block before the first mechanical roller valve, the gas circuit of the second cylinder is closed, and the piston rod of the cylinder is no longer affected by the pressure of the gas in the cylinder body. When the sliding mechanism is pushed, it can compress the piston rod back into the cylinder. After that, when the gas introduction is completed, the sliding mechanism is dislocated from the mounting plate, and the second mechanical roller valve goes downhill, so that the gas circuit of the second cylinder is opened, the cylinder is filled with air, the piston rod is pushed out, and at the same time the sliding mechanism is driven back to the initial position, waiting for the next gas introduction process.

[0013] As another preferred solution, the reset device is a spring, one end of which is connected to the connecting plate at the bottom of the frame, and the other end is connected to the base, and the spring is parallel to the guide rail. In this way, the reset device in this solution directly uses a spring, and when the positioning push block is stuck by the protrusion, the sliding mechanism moves on the track, and when the sliding mechanism moves forward, the spring is compressed or stretched. When the sliding mechanism is separated from the action of the mounting plate, the restoring force of the spring brings the sliding mechanism back to the initial position, waiting for the next gas introduction process.

[0014] Preferably, the spring is a stainless steel spring. In this way, the stainless steel spring can extend the service life of the device.

[0015] Furthermore, the first impact block and the second impact block are both isosceles trapezoidal structures, the lower base of the first impact block is closely connected to the impact rail, and the lower base of the second impact block is closely connected to the plate surface where the positioning push block is located on the mounting plate. In this way, the slopes on both sides of the isosceles trapezoidal structure are consistent, so that the first mechanical roller valve, the second mechanical roller valve and the second mechanical roller valve are more stably stressed.

[0016] Compared with the prior art, the beneficial effects are:

[0017] 1. The structural design of the present invention is ingenious. Through the driving effect of the mounting plate on the friction line and the cooperation of the sliding mechanism and the track mechanism structure, the opening and closing of the first mechanical roller valve and the second mechanical roller valve are controlled, thereby controlling the introduction of gas. When the sliding mechanism is dislocated from the mounting plate, the reset device brings the sliding mechanism back to the initial position to prepare for the next gas introduction. This reciprocating process can be applied to the gas introduction of conveying equipment without manual operation, realizing the automation and programming of gas introduction and improving production efficiency.

[0024] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0025] Example 1

[0026] like Figure 1As shown, a track mechanism 1 includes a base 11, two guide rails 16, a striking rail 12, a dislocation rail 14 and a reset device are arranged above the base 11, one end of the reset device is connected to one end of the base 11, the guide rail 16, the striking rail 12 and the dislocation rail 14 are parallel to each other, a first striking block 13 of a trapezoidal structure is arranged on the striking rail 12, and a dislocation block 15 of a right-angled trapezoidal structure is arranged on the dislocation rail 14. The dislocation rail 14 is located between the two parallel guide rails 16, and the striking rail 12 is located outside the two guide rails 16; the lower bottom of the dislocation block 15 is fixedly attached to the dislocation rail 14, and the hypotenuse of the dislocation block 15 is located at one end of the dislocation block 15 close to the first striking block 13; a limiting protrusion is arranged on the upper bottom of the dislocation block 15 close to the straight waist of the dislocation block 15.

[0027] It is equivalent to having four parallel tracks on a base 11, which are used for different mechanism functions. A trapezoidal first impact block 13 is set on the impact rail 12, which can make the wheels on the sliding mechanism 3 have an uphill and a downhill process when running on it, changing the running state of the wheels; similarly, the dislocation block 15 can also play this role, and the guide rail 16 can be used for the guided sliding of an integral sliding mechanism 3 above. There are two guide rails 16, which can achieve the function of guiding sliding. The structure is the simplest. The dislocation rail 14 is in the middle and the impact rail 12 is on the outside, which can be more reasonable in layout. The dislocation block 15 and the first impact block 13 do not correspond to the same position on the guide rail 16. On the travel of the guide rail 16, it first passes through the first impact block 13 and then passes through the dislocation block 15. Both the first impact block 13 and the dislocation block 15 first go through an uphill process to change the motion state. The role of the limiting protrusion is to prevent the sliding mechanism 3 from overtravel, so that it will not move forward from the dislocation block 15 after completing the change of motion state after going uphill.

[0029] A gas introduction device is also provided, such as Figures 1 to 6 As shown, a gas introduction device comprises a mounting plate 2, a sliding mechanism 3 and the above-mentioned track mechanism 1 which are arranged in sequence;

[0030] The mounting plate 2 is provided with an air receiving structure 22 and a positioning push block 21;

[0031] The sliding mechanism 3 includes a frame 31, on which are provided a movable rod 34, a first cylinder 32, an air intake structure 33 capable of aligning with the air receiving structure 22, and a first mechanical roller valve 39 for controlling the common air path of the first cylinder 32 and the air intake structure 33. The air intake structure 33 is connected to the piston rod of the first cylinder 32. The frame 31 is connected to the guide rail 16 and can move on the guide rail 16. The middle part of the movable rod 34 is connected to the frame 31 through a rotating shaft, and the movable rod can rotate around the rotating shaft. A protrusion 35 is fixedly connected to one end of the movable rod 34, and the protrusion 35 can be contacted and connected with the positioning push block 21. A roller rod 36 is connected to the other end of the movable rod 34. A roller 38 used in conjunction with the dislocation rail 14 is provided at the end of the roller rod 36 away from the movable rod 34. The first mechanical roller valve 39 is located at the bottom of the frame 31 and can move on the impact rail 12. The other end of the reset device is fixedly connected to the frame 31.

[0032] In this embodiment, the reset device is a second cylinder 17, the cylinder body of the second cylinder 17 is fixed on the base 11, the rod head of the piston rod 18 of the second cylinder 17 is fixedly connected to the connecting plate 40 at the bottom of the frame 31, a second impact block 19 of a trapezoidal structure is provided on the mounting plate 2, a second mechanical roller valve 37 for controlling the gas path of the second cylinder 17 is provided on the top of the frame 31, the second mechanical roller valve 37 can move on the second impact block 19, and the piston rod 18 of the second cylinder 17 is parallel to the guide rail 16. The first impact block 13 and the second impact block 19 are both isosceles trapezoidal structures, the lower bottom of the first impact block 13 is closely connected to the impact rail 12, and the lower bottom of the second impact block 19 is closely connected to the plate surface of the mounting plate 2 where the positioning push block 21 is located.

[0033] On the basis of the track mechanism 1 set on the ground, the sliding mechanism 3 changes its motion state by cooperating with the track mechanism 1 to achieve the control of gas introduction. The whole operation process is very clever. The working process is roughly as follows: first, the mounting plate 2 is used to install the purification unit. The gas connection structure 22 is set on the plate. The gas connection structure 22 is connected with the purification unit. This belongs to the prior art and does not need to be described in detail. The mounting plate 2 carries the purification unit as a whole and moves on the friction line above. The track mechanism 1 and the sliding mechanism 3 are set below a certain point of the friction line to cooperate with the mounting plate 2. When the mounting plate 2 moves to the sliding mechanism 3, the positioning push block 21 under the mounting plate 2 is connected with the protrusion 35 on the movable rod 34. The projection 35 is in a state perpendicular to the horizontal plane, and the projection 35 is preferably perpendicular to the movable rod 34, the movable rod 34 is in a horizontal position, and the roller rod 36 is also perpendicular to the movable rod 34, and the roller rod 36 contacts the dislocation rail 14 through the roller 38 at the other end of the movable rod 34; the positioning push block 21 is stuck by the vertical projection 35, and when the mounting plate 2 continues to move forward under the action of power, the sliding mechanism 3 below can be pushed by the positioning push block 21 to move on the track mechanism 1, and the sliding mechanism 3 frame 31 on one side is lowered A first mechanical roller valve 39 is provided, and the first mechanical roller valve 39 moves forward on the impact rail 12. When the first mechanical roller valve 39 moves to the first impact block 13 and rolls up the slope of one side of the trapezoidal first impact block 13, it can open the common passage between the first cylinder 32 and the air intake structure 33. The first cylinder 32 is arranged vertically on a horizontal plane, and the piston rod of the first cylinder 32 faces the air receiving structure 22. The air outlet pipe of the air intake structure 33 fixedly provided at the rod head of the piston rod of the first cylinder 32 also faces the air receiving structure 22. When the piston rod of the first cylinder 32 extends upward, the air intake structure 33 introduces gas to the air receiving structure 22. The connection position between the air intake structure 33 and the air receiving structure 22 is made of rubber material, which has a certain sealing performance. When the air intake structure 33 and the air receiving structure 22 are in place, the power device control mounting plate 2 stays at this position for a period of time, and the piston rod of the first cylinder 32 no longer extends upward to ensure the safety of the device. This can be achieved by setting the specific position of the first cylinder 32 or setting a corresponding sensor.Afterwards, when the air intake structure 33 and the air receiving structure 22 have completed the introduction of gas, the power device continues to drive the mounting plate 2 to move forward along the friction line. At this time, the first mechanical roller valve 39 goes down the slope, the corresponding air circuit is closed, and the piston rod of the first cylinder 32 retracts; the roller 38 on the roller rod 36 continues to move on the dislocation rail 14, and then moves to the dislocation block 15. Since the movable rod 34 and the frame 31 are hinged, when the roller 38 goes up the slope of the dislocation block 15, the roller rod 36 can cause the movable rod 34 to rotate, and the rotation of the movable rod 34 also causes the protrusion 35 to move. The protrusion 35 disengages from the positioning push block 21, and also causes the mounting plate 2 to no longer push the sliding mechanism 3 forward, completing the dislocation of the mounting plate 2 and the sliding mechanism 3; in addition, since a reset device is also provided on the track mechanism 1, in this embodiment, the reset device mainly includes the second cylinder 17 and the second mechanical roller valve 37, and the gas pipeline assembly of the second cylinder 17 is installed There is the second mechanical roller valve 37, which controls the gas passage of the second cylinder 17. The second mechanical roller valve 37 is located at the top, and the structural design is more reasonable, making the setting easier. When the positioning push block 21 of the mounting plate 2 contacts the protrusion 35 of the sliding mechanism 3, the second mechanical roller valve 37 moves to the second impact block 19, so that the gas circuit of the second cylinder 17 is closed, and the piston rod 18 of the second cylinder 17 is no longer subjected to the pressure of the gas in the cylinder barrel, and the sliding mechanism 3 compresses the piston rod 18 back into the cylinder barrel of the cylinder. When the mounting plate 2 and the sliding mechanism 3 are dislocated, the second mechanical roller valve 37 is no longer affected by the second impact block 19, and the gas circuit of the second cylinder 17 is opened, so that the cylinder is inflated, the piston rod 18 is pushed out, and at the same time, the sliding mechanism 3 is driven back to the initial position, waiting for the next gas introduction process. This reciprocating process can realize the automation and programming of gas introduction and improve production efficiency.

The second mechanical roller valve 37 controls the air circuit of the second cylinder 17. Both the first mechanical roller valve 39 and the second mechanical roller valve 37 can move on the impact rail 12, and the second mechanical roller valve 37 is located between the first mechanical roller valve 39 and the first impact block 13.

[0037] The reset device used in this embodiment mainly includes a second cylinder 17 and a second mechanical roller valve 3737. The gas pipeline assembly of the second cylinder 17 is installed with the second mechanical roller valve 37. The gas passage of the second cylinder 17 is controlled by the second mechanical roller valve 37. When the second mechanical roller valve 37 contacts the first impact block 13 before the first mechanical roller valve 39, the gas circuit of the second cylinder 17 is closed, and the piston rod 18 of the cylinder is no longer affected by the pressure of the gas in the cylinder body. When the sliding mechanism 3 is pushed, it can compress the piston rod 18 back into the cylinder. After that, when the gas introduction is completed, the sliding mechanism 3 is dislocated from the mounting plate 2, and the second mechanical roller valve 37 goes downhill, so that the gas circuit of the second cylinder 17 is opened, the cylinder is filled with air, the piston rod 18 is pushed out, and at the same time the sliding mechanism 3 is driven back to the initial position to wait for the next gas introduction process.

[0038] Example 4

[0039] This embodiment is similar to Embodiment 2, except that:

[0040] In this embodiment, the reset device is a stainless steel spring, one end of which is connected to the connecting plate 40 at the bottom of the frame 31 , and the other end of which is connected to the base 11 . The stainless steel spring is parallel to the guide rail 16 .

[0041] In this embodiment, the reset device directly adopts a stainless steel spring. When the positioning push block 21 is stuck by the protrusion 35, the sliding mechanism 3 moves on the track. When the sliding mechanism 3 moves forward, the stainless steel spring is compressed or stretched. When the sliding mechanism 3 is separated from the mounting plate 2, the restoring force of the stainless steel spring brings the sliding mechanism 3 back to the initial position, waiting for the next gas introduction process. The stainless steel spring can extend the service life of the device.
