[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] like Figures 1 to 5 As shown, the first embodiment of the present invention provides a car blocker 6, which is arranged in a placement cavity, and the placement cavity is lower than the working surface. Specifically, a placement cavity is excavated at the work site, and a working surface is formed at the work site except for the area where the placement cavity is located. The car blocker 6 includes a car blocker structure 10, a drive assembly 20 and a transmission assembly 30. The car blocker structure 10 has a car blocker position and an avoidance position. When the car blocker structure 10 is at the car blocker position, at least a part of the car blocker structure 10 protrudes from the working surface. When the car blocker structure 10 is at the avoidance position, the car blocker structure 10 is located in the placement cavity. The driving assembly 20 has a fixed end 2111 and a driving end 2121 that are relatively arranged, and the fixed end 2111 is fixed in the placement cavity; the transmission assembly 30 is arranged in the placement cavity, and the driving end 2121 is driven and connected to one end of the transmission assembly 30 to drive the transmission assembly 30 to rotate. The rotation axis of the transmission assembly 30 extends in the horizontal direction, and the other end of the transmission assembly 30 is connected to the vehicle-blocking structure 10. The driving assembly 20 drives the vehicle-blocking structure 10 to move between the vehicle-blocking position and the avoidance position through the transmission assembly 30.

[0046] By applying the technical solution of the present application, the drive assembly 20 can drive the car blocking structure 10 to move between the car blocking position and the avoidance position through the transmission assembly 30. When the car blocking structure 10 is in the car blocking position, the car blocking structure 10 protrudes from the working surface and can limit the tube bundle trailer. When the car blocking structure 10 is in the avoidance position, the car blocking structure 10 is located in the placement cavity, which can avoid interference with the tires of the tube bundle trailer and ensure the normal travel of the tube bundle trailer. In this way, the car blocker 6 does not need to move the position of the staff during operation. It only needs to operate the drive assembly 20 to work, thereby avoiding personal injury to the staff when the vehicle is not fully braked, and thus ensuring the personal safety of the staff. In addition, the drive end 2121 is connected to the transmission assembly 30 for driving, so as to drive the car blocking structure 10 to move in the vertical direction by driving the transmission assembly 30 to rotate. Such an arrangement facilitates placement of the drive assembly 20 and the transmission assembly 30 in the placement cavity, avoiding excessive depth of the placement cavity, thereby ensuring that the depth of the placement cavity meets the construction requirements of the hydrogen refueling station and avoiding safety problems at the hydrogen refueling station.

[0047] Among them, in the prior art, the movable car blocker is usually made of rubber material, which can reduce the weight of the movable car blocker and facilitate its movement. However, the movable car blocker is very easy to be damaged during use, thereby affecting the blocking effect of the movable car blocker.

[0048] In the present application, the car-blocking structure 10 can be made of metal materials such as stainless steel. Such a configuration can improve the structural strength of the car-blocking structure 10, avoid damage to the car-blocking structure 10, and ensure the car-blocking effect of the car blocker 6.

[0049] Specifically, the transmission assembly 30 includes a transmission member 31, a fixed shaft 33, and a support member 32. The fixed shaft 33 is fixed in the placement cavity, and the fixed shaft 33 is arranged in the horizontal direction. The transmission member 31 has a connecting hole, which is rotatably mounted on the fixed shaft 33, and the driving end 2121 is rotatably connected to one end of the transmission member 31. In the present application, one end of the transmission member 31 is hingedly connected to the driving end 2121. The other end of the transmission member 31 is drive-connected to the support member 32, and the support member 32 can abut against the vehicle-blocking structure 10. The driving assembly 20 can drive the support member 32 to move in the vertical direction through the transmission member 31. Such a setting can ensure the contact area between the support member 32 and the vehicle-blocking structure 10 during the rotation of the transmission member 31, ensure the driving effect of the drive component 20 on the vehicle-blocking structure 10, and further ensure the normal movement of the vehicle-blocking structure 10 between the vehicle-blocking position and the avoidance position, ensure the stability of the vehicle-blocking structure 10 during the movement, and at the same time reduce the depth of the placement cavity to meet the construction requirements of the hydrogen refueling station.

[0050] The support member 32 has a connecting shaft 321. The transmission member 31 is provided with a sliding hole 311, which extends along the length of the transmission member 31. The connecting shaft 321 is slidably inserted into the sliding hole 311. When the transmission member 31 rotates, the connecting shaft 321 slides along the extension direction of the sliding hole 311, thereby driving the support member 32 in a vertical direction. This arrangement prevents interference between the transmission member 31 and the support member 32, simplifies the connection between the transmission member 31 and the support member 32, facilitates the sliding and rotation of the support member 32 relative to the transmission member 31, and facilitates machining of the transmission member 31.

[0051] Specifically, in the present application, the support member 32 includes a connecting block 324, and the connecting shaft 321 is arranged on the connecting block 324. Such an arrangement can improve the structural strength of the support member 32, avoid damage to the connecting shaft 321 during the movement of the support member 32 relative to the transmission member 31, and improve the service life of the support member 32.

[0052] Furthermore, in the present application, a slot is provided on the transmission member 31, and sliding holes 311 are provided on both side walls of the slot. Two connecting shafts 321 are provided on the connecting block 324, and the two connecting shafts 321 are arranged in a one-to-one correspondence with the two sliding holes 311. The connecting block 324 is located in the slot. Such a setting can ensure the connection strength between the support member 32 and the transmission member 31, and prevent the support member 32 from falling off the transmission member 31, thereby ensuring the stability of the support member 32 during operation.

[0053] Specifically, the slot is provided at an end of the fixed shaft 33 away from the driving assembly 20 .

[0054] Among them, the driving assembly 20 includes a driving structure 21, the driving structure 21 includes a sleeve 211 and a telescopic rod 212, one end of the sleeve 211 is a fixed end 2111, one end of the telescopic rod 212 is slidably set at the other end of the sleeve 211, and the other end of the telescopic rod 212 is a driving end 2121. The driving structure 21 can drive the car-blocking structure 10 to move from the car-blocking position to the avoidance position.

[0055] With this arrangement, when the telescopic rod 212 is extended from the sleeve 211, the support member 32 moves downward, and the collision-blocking head 11 moves to the avoidance position. When the telescopic rod 212 is retracted into the sleeve 211, the support member 32 moves upward, and the collision-blocking head 11 moves to the vehicle-blocking position. When the drive structure 21 is in operation, the telescopic rod 212 extends from the sleeve 211. When the drive structure 21 is not in operation, the telescopic rod 212 is located within the sleeve 211. Since the vehicle-blocking structure 10 is in the vehicle-blocking position most of the time, that is, the drive structure is not in operation most of the time, this can reduce the usage time of the drive structure 21, increase the service life of the drive structure 21, and prevent damage to the drive structure 21.

[0056] Furthermore, the driving structure 21 is a pneumatic push rod. This configuration can simplify the structure of the driving assembly 20, reduce the cost of the driving assembly 20, and improve the response speed of the driving assembly 20, making it easier to drive the support member 32 to move in the vertical direction.

[0057] Hydraulic car arresters are currently used in some work environments. They are durable, offer high load capacity, operate smoothly, operate quietly, are fast, have a long lifespan, and can be automatically controlled and linked with other equipment. However, they are expensive, have numerous accessories, and have a complex control system. Furthermore, hydrogen refueling stations must meet explosion-proof requirements, so conventional hydraulic car arresters cannot be used in explosion-proof areas, posing an explosion risk.

[0058] However, in the present application, the gas source 1 of the pneumatic push rod adopts inert gas, and the pneumatic push rod meets the on-site requirements in the hydrogenation station, thereby ensuring the safety of the car arrester 6 during operation.

[0059] Optionally, the gas source 1 of the pneumatic push rod may be nitrogen.

[0060] Specifically, the car blocker 6 includes two drive structures 21 and two transmission members 31. The two drive structures 21 are arranged in a one-to-one correspondence with the two transmission members 31, and the two drive structures 21 are arranged gradually away from each other in the direction approaching the car blocker structure 10. That is, in this application, the drive structures 21 and the transmission members 31 are arranged at an angle, which can reduce the depth of the placement cavity and reduce the workload of the staff.

[0061] Furthermore, the driving assembly 20 also includes a base 22 and a reset member 23. The base 22 is fixed in the placement cavity. The reset member 23 is arranged between the base 22 and the support member 32. The reset member 23 can drive the car-blocking structure 10 to move from the avoidance position to the car-blocking position through the support member 32. Such an arrangement facilitates driving the car-blocking structure 10 to move from the avoidance position to the car-blocking position. At the same time, the reset member 23 can support the support member 32 to ensure the stability of the car-blocking structure in the car-blocking position.

[0062] In this application, the reset member 23 is a spring.

[0063] Furthermore, in the present application, the driving assembly 20 further includes a fixing structure 24, and the base 22 is fixed on the fixing structure 24. With such a configuration, when the car blocker 6 is fixed in the placement cavity, the car blocker 6 can be directly placed in the placement cavity, and then the fixing shaft 33 is fixed in the placement cavity, which makes it easy for the staff to install the car blocker 6 and is easy to operate.

[0064] Specifically, the car-blocking structure 10 includes a collision head 11, which is arranged on a support member 32. The collision head 11 has a car-blocking surface 113 and a first end 111 and a second end 112 arranged opposite to each other. The car-blocking surface 113 is arranged between the first end 111 and the second end 112 of the collision head 11, and the second end 112 of the collision head 11 is used to be arranged close to the tire. When the car-blocking structure 10 is in the car-blocking position, the vertical cross-sectional area of ​​the collision head 11 gradually decreases from the first end 111 to the second end 112 of the collision head 11. With such a configuration, the weight of the collision head 11 can be reduced while increasing the area of ​​the car-blocking surface 113, thereby facilitating the installation of the collision head 11 and ensuring the car-blocking effect of the collision head 11.

[0065] Furthermore, in the present application, a stopper 6 is provided in front and behind each tire of the tube bundle trailer, with the stopper surface provided corresponding to the tire. With this arrangement, if one of the stoppers 6 is damaged, the remaining stoppers 6 can still normally limit the position of the tube bundle trailer, preventing the tube bundle trailer from moving during operation, further preventing workers from being injured.

[0066] like Figures 1 to 4As shown, a connecting hole 3221 is provided on the support member 32. The car blocker 6 also includes a connecting member 40, which is inserted into the connecting hole 3221. The connecting member 40 has a connecting portion 41 at one end close to the car blocker structure 10. The connecting portion 41 is located above the support member 32. The car blocker structure 10 is rotatably connected to the connecting portion 41, and the collision head 11 can rotate relative to the support member 32. In this way, when the car blocker structure 10 moves to the car blocker position, the tire can abut against the second end 112 of the collision head 11. At this time, the car blocker structure 10 can rotate, and the car blocker surface 113 can block the tire. In this way, the collision head 11 is variable in height during the rotation process, which is convenient for storing the car blocker 6 and facilitating the car blocker structure 10 to move to the avoidance position. At the same time, the collision between the collision head 11 and the tire can be reduced, avoiding damage to the tire and improving the service life of the tire.

[0067] In the present application, the rotation axis of the transmission member 31 is perpendicular to the rotation axis of the vehicle blocking structure 10 , and the rotation axis of the transmission member 31 and the rotation axis of the vehicle blocking structure 10 are both horizontally arranged.

[0068] like Figure 4 As shown, the connecting member 40 has a guide rod 42. In addition, a through hole is provided on the base 22. The guide rod 42 is inserted into the connecting hole 3221 and the through hole. The reset member 23 is sleeved on the guide rod 42. In this arrangement, the guide rod 42 can guide the reset member 23, preventing the reset member 23 from tilting during the force application process, thereby ensuring the normal operation of the reset member 23.

[0069] like Figure 5 As shown, the car blocker 6 further includes a pad 50, which is sleeved on the guide rod 42 and disposed between the reset member 23 and the support plate 322. This arrangement ensures uniform force on the reset member 23, thereby ensuring the stability of the car blocker structure 10 when it moves to the avoidance position, while facilitating the reset member 23 to drive the car blocker structure 10 to move to the car blocker position.

[0070] In this application, the pad 50 has a connecting section 51 and an abutting section 52, the outer diameter of the connecting section 51 is smaller than the outer diameter of the abutting section 52, the through hole includes a first hole section and a second hole section, the first hole section is set away from the reset member 23, and the second hole section is set close to the reset member 23, the diameter of the first hole section is smaller than the diameter of the second hole section, the connecting section 51 is located in the second hole section, and the end face of the abutting section 52 abuts against the end face of the support plate 322.

[0071] Specifically, in the present application, two connecting members 40 are provided on the support member 32, and the two connecting members 40 are spaced apart along the length direction of the support member 32. A reset member 23 is sleeved on the outer side of each guide rod 42. Such a setting can further ensure the stability of the support member 32 during the movement in the vertical direction.

[0072] like Figure 2 and Figure 4 As shown, the connecting portion 41 has a connecting groove 411, and the bottom of the first end of the collision prevention head 11 has a mounting groove 114. The collision prevention head 11 has a first limit angle and a second limit angle relatively set relative to the support member 32, and a limiting structure is provided between the first end 111 of the collision prevention head 11 and the support member 32 to limit the rotation of the collision prevention head 11 between the first limit angle and the second limit angle. The vehicle blocking structure 10 also includes a rotating shaft 12, which is fixed in the mounting groove 114, and the rotating shaft 12 is rotatably set in the connecting groove 411. Such a configuration facilitates the rotation of the collision prevention head 11 and avoids interference between the connecting portion 41 and the collision prevention head 11. At the same time, it can limit the rotation angle of the collision prevention head 11 to ensure the limiting effect of the collision prevention head 11.

[0073] Furthermore, the collision prevention head 11 has two installation grooves 114 , and the two installation grooves 114 are arranged in a one-to-one correspondence with the two connecting members 40 .

[0074] Among them, the car-blocking structure also includes a gear 13 and a fixing plate 14, the gear 13 and the fixing plate 14 are fixedly connected, and the gear 13 is fixedly connected to the rotating shaft 12, and the fixing plate 14 is detachably connected to the connecting groove 411. This arrangement facilitates the replacement of the rotating shaft 12 and facilitates the staff to repair the car-blocking structure 10.

[0075] Specifically, the connecting portion 41 may be designed as a split structure, which facilitates fixing the rotating shaft 12 in the connecting groove 411 .

[0076] like Figure 2 and Figure 3 As shown, the first end 111 of the collision head 11 has a contact surface 115. The support member 32 includes a support plate 322 and a contact block 323. When the collision head 11 is located at the first extreme angle, the side wall of the collision head 11 abuts against the support plate 322. At this time, the angle between the vehicle blocking surface 113 and the horizontal plane is the largest, and the collision head 11 can limit the tire. That is, the vehicle blocking structure 10 is located at the vehicle blocking position. The contact block 323 is arranged on the support plate 322, and the contact block 323 has a support surface 3231. When the collision head 11 is located at the second extreme angle, the abutment surface 115 abuts against the support surface 3231. The support surface 3231, the support plate 322 and the abutment surface 115 cooperate to form a limiting structure. At this time, the angle between the vehicle blocking surface 113 and the horizontal plane is the smallest, which is convenient for the tube bundle trailer to travel.

[0077] There are two limiting structures between the car blocking structure 10 and the support member 32, and the two limiting structures are respectively located on both sides of the car blocking structure 10. Such an arrangement can further ensure the stability of the collision blocking head 11 and further prevent the collision blocking head 11 from shaking when in the car blocking position and the avoidance position.

[0078] Furthermore, the bottom of the first end 111 of the collision block 11 is provided with a curved surface 116, which is connected to the abutment surface 115. The abutment block 323 is provided with a curved structure 3232. The support surface 3231 is located above the curved structure 3232, and the curved surface 116 and the curved structure 3232 are adapted to each other. This arrangement facilitates the rotation of the collision block 11 relative to the support plate 322, thereby facilitating the collision block 11 to limit the position of the tube bundle trailer.

[0079] The second embodiment of the present invention provides a car blocker 6 , which differs from the first embodiment in that the blocker head 11 is fixedly connected to the support member 32 . This arrangement reduces the number of parts in the car blocker 6 , facilitates assembly of the car blocker 6 , and reduces the cost of the car blocker 6 . Alternatively, the blocker head 11 and the support member 32 may be welded or bolted.

[0080] like Figure 6 As shown, the third embodiment of the present invention provides a car blocking system, which includes a power source, a control component, and the above-mentioned car blocker 6. The power source is drivingly connected to the drive component 20 of the car blocker 6, and the control component is electrically connected to the power source. The control component controls the operation of the drive component 20 through the power source. This arrangement can improve the degree of automation of the car blocking system, facilitate the operation of the car blocker 6, and reduce the labor intensity of the staff.

[0081] In this application, the power source is an air source 1. The control assembly includes a pressure gauge 2, a needle valve 3, a vent valve 4, a pneumatic valve 5, a control structure 7, and an interlock switch 8.

[0082] An air supply pipeline is provided between the air source 1 and the car arrester 6, that is, the air source 1 is connected to the drive assembly 20. Along the direction from the air source 1 to the car arrester 6, a pressure gauge 2, a needle valve 3 and a pneumatic valve 5 are sequentially provided on the air supply pipeline. The pressure gauge 2 can detect the air pressure in the air supply pipeline, and the needle valve 3 can control the delivery of gas in the air supply pipeline. The control structure 7 is electrically connected to the interlocking switch 8 and the pneumatic valve 5. The interlocking switch 8, the control structure 7 and the pneumatic valve 5 are arranged in series. When the interlocking switch 8 and the control structure 7 are opened at the same time, the pneumatic valve 5 can be opened and the telescopic rod 212 can be extended from the sleeve 211.

[0083] There is a vent valve 4 between the needle valve 3 and the pneumatic valve 5. When the car arrester 6 needs to be repaired, the needle valve 3 can be closed, the vent valve 4 can be opened, the gas in the car arrester can be released, and then the car arrester 6 can be repaired. This arrangement can avoid the loss of nitrogen.

[0084] Furthermore, the control structure 7 includes an electrical cabinet, which has a pressure switch. When the pressure switch is in a natural state, the pressure switch is in a disconnected state, that is, the control structure 7 is in a disconnected state, the pneumatic valve 5 cannot be opened, the telescopic rod 212 is located in the sleeve 211, and the vehicle blocking structure 10 is in a vehicle blocking position.

[0085] When supplying hydrogen to a hydrogen refueling station, a trailer hose is typically used. One end of the trailer hose connects to the storage tank on the tube bundle trailer, while the other end delivers hydrogen to the station. A hook is provided on the electrical cabinet. Only when the trailer hose is secured to the hook and the pressure switch is closed by the weight of the trailer hose, the control structure 7 is in a connected state. At this point, the pneumatic valve 5 can be opened, and the telescopic rod 212 can be extended from the sleeve 211. This arrangement prevents displacement of the tube bundle trailer during hydrogen refueling at the station, thus ensuring that hydrogen refueling can proceed normally.
