Description

Technical Field

[0001] This utility model belongs to the field of control cabinet technology and relates to a highway ETC gantry control cabinet. Background Technology

[0002] After the implementation of electronic non-stop toll collection on highways, highway gantries take on functions such as route identification and automatic toll calculation for passing vehicles, making them a crucial facility for achieving contactless electronic toll collection on highways. The highway gantry system includes electromechanical equipment such as license plate recognition cameras and back-end servers. In the daily operation and maintenance of highway ETC gantry equipment, one aspect requires the inspection and repair of the equipment inside the cabinet. Due to the limited space within the cabinet, this inspection and repair is extremely laborious and inconvenient to operate.

[0003] To this end, a Chinese patent discloses a highway ETC gantry cabinet [authorization announcement number CN220915610U], which includes a cabinet body, a movable seat, a rotating seat, and a counterweight; the movable seat is located at the bottom of the cabinet body and can move parallel to the direction of the cabinet door; the rotating seat is rotatably located above the movable seat; a storage cavity is provided in the lower part of the cabinet body; the storage cavity has an opening on the back of the cabinet body, and the counterweight is located in the storage cavity.

[0004] The aforementioned cabinet requires equipment to be moved out of the cabinet for maintenance. Supporting the equipment solely with movable bases and sliding rods makes the cabinet prone to instability or even tipping over due to the forward shift of the equipment's center of gravity. Although counterweights are installed inside the storage cavity, the weight of the moved equipment acts on the sliding rods, making them susceptible to breakage. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a highway ETC gantry control cabinet that can stably support equipment during relocation.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] The highway ETC gantry control cabinet includes a cabinet with an internal cavity, a cabinet door hinged to the front of the cabinet to seal the internal cavity, a first guide rail located at the bottom of the internal cavity and extending in the front-rear direction, and a base plate slidably mounted on the first guide rail for mounting equipment. The end of the first guide rail near the cabinet door is hinged to a second guide rail that can swing vertically to horizontally. The base plate can slide onto the horizontal second guide rail. The second guide rail is provided with a support structure for supporting the horizontal second guide rail. The internal cavity is also provided with a locking structure for locking the vertical second guide rail.

[0008] Under normal conditions, the second guide rail swings to a vertical position around its hinge point with the first guide rail and is locked in place by a locking mechanism, limiting the position of the base plate and equipment and preventing the base plate from sliding on the first guide rail. When maintenance is required, the cabinet door is opened and the locking mechanism is unlocked, allowing the second guide rail to swing from a vertical position to a horizontal position. The second guide rail is then supported by a support structure. At this point, the first and second guide rails form a complete long guide rail, with its outer end extending outside the inner cavity. The base plate can then slide along the first guide rail onto the second guide rail, allowing the equipment mounted on the base plate to be moved outside the cabinet for easy maintenance.

[0009] The first guide rail consists of two parallel rails. Each first guide rail is hinged to a second guide rail at the end closest to the cabinet door. The two second guide rails are connected together by a horizontally extending connecting rod to ensure that the two guide rails can move synchronously.

[0010] In the aforementioned highway ETC gantry control cabinet, the support structure includes a strut fixed at the end of the second guide rail away from the first guide rail. The strut is set perpendicular to the second guide rail, and the second guide rail is in a horizontal state when the lower end of the strut is supported on the ground.

[0011] There are two struts, which are fixed to different second guide rails respectively. The two struts are symmetrically arranged to ensure the stability of the whole structure composed of the two second guide rails and the connecting rod.

[0012] In the aforementioned highway ETC gantry control cabinet, the support structure includes a swing rod connected to the side of the second guide rail away from the first guide rail. When the second guide rail is in a vertical state, the swing rod is in a vertical state. When the second guide rail is in a horizontal state, the swing rod is in a vertical state and its lower end is supported on the ground. A positioning structure is provided between the swing rod and the second guide rail to keep the swing rod supported on the ground in its current state.

[0013] There are two swing arms, each hinged to a different second guide rail. The two swing arms are symmetrically arranged to ensure the stability of the whole structure formed by the two second guide rails and the connecting rod. The swing arms are rotatably mounted on the second guide rails to prevent them from hitting the cabinet door.

[0014] In the aforementioned highway ETC gantry control cabinet, the positioning structure includes a guide hole on the side of the swing arm facing the second guide rail, a spring and a ball bearing inside the guide hole. The guide hole extends horizontally and is perpendicular to the second guide rail. The side of the second guide rail facing the swing arm has a positioning cavity. When the second guide rail is in a horizontal state, the ball bearing is positioned in the positioning cavity under the action of the spring. At this time, the swing arm is in a vertical state, and the positioning cavity is located directly below the hinge point between the swing arm and the second guide rail.

[0015] One end of the spring rests against the inner end of the guide hole, while the other end acts on the ball bearing, providing a constant outward force to drive the ball bearing. During rotation, the guide hole is always blocked by the side of the second guide rail, preventing the ball bearing and spring from dislodging from the guide hole. The positioning cavity is hemispherical, with a depth less than the radius of the ball bearing. The guide hole, spring, ball bearing, and positioning cavity ensure the swing arm remains vertically supported, improving stability. When no support is needed, swinging the swing arm allows the ball bearing to dislodge from the positioning cavity, preventing the swing arm from hitting the cabinet door when closing and ensuring the door remains securely closed.

[0016] In the aforementioned highway ETC gantry control cabinet, the locking structure includes a through hole in the second guide rail, a positioning rod slidably disposed in the through hole, and a positioning hole at the bottom of the inner cavity. When the second guide rail is in a vertical state, the through hole is located directly above the positioning hole, and the lower end of the positioning rod is inserted into the positioning hole to lock the second guide rail.

[0017] The length of the positioning rod is greater than the length of the through hole. When the lower end of the positioning rod extends into the positioning hole, the upper end of the positioning rod still protrudes from the upper end of the through hole. When the positioning rod is inserted into the positioning hole, the second guide rail can be locked in a vertical state, thereby achieving the purpose of limiting the position of the base plate.

[0018] Each second guide rail is equipped with a through hole and a positioning rod. The two positioning rods are connected together by a crossbar to ensure that the two positioning rods can move synchronously.

[0019] In the aforementioned highway ETC gantry control cabinet, a positioning block is provided on the second guide rail. The inner end of the base plate, which is positioned on the first guide rail, abuts against the positioning block, and its outer end abuts against the second guide rail, which is in a vertical state.

[0020] The base plate is positioned by the cooperation of the positioning block and the vertical second guide rail.

[0021] In the aforementioned highway ETC gantry control cabinet, the first guide rail and the second guide rail are hinged together. One movable leaf of the hinge is attached to the upper surface of the first guide rail, and the other movable leaf of the hinge is attached to the upper surface of the second guide rail.

[0022] In the aforementioned highway ETC gantry control cabinet, a slider is slidably mounted on the first guide rail, and the base plate is fixed to the slider. The slider can slide onto a horizontal second guide rail. To facilitate the slider's movement on the first and second guide rails, a first groove is provided on one side of the first guide rail, and a second groove is provided on the other side; a third groove is provided on one side of the second guide rail, and a fourth groove is provided on the other side. When the second guide rail is horizontal, the slider can slide from the first groove into the third groove, and from the second groove into the fourth groove.

[0023] Compared with existing technologies, the ETC gantry control cabinet of this highway has the following advantages:

[0024] By setting up a support structure to support the second guide rail, the stability of the second guide rail is improved, thereby enhancing the support for the equipment and preventing cabinet instability. When maintenance is required, first unlock the second guide rail, then open the support structure, and then slide the base plate out of the cavity. The operation is simple. After storage, the support structure will not press against the cabinet door, preventing the cabinet door from being unable to close. Attached Figure Description

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0034] like Figure 1 , Figure 2 and Figure 6The highway ETC gantry control cabinet shown includes a cabinet body 1 with an internal cavity, a cabinet door 2 hinged to the front of the cabinet body 1 for sealing the internal cavity, a first guide rail 3 located at the bottom of the internal cavity and extending in the front-back direction, and a base plate 4 slidably mounted on the first guide rail 3 for installing equipment. There are two first guide rails 3 that are parallel to each other, and a slider 11 is slidably mounted on each first guide rail 3. The base plate 4 is fixed on the slider 11.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, a second guide rail 5, which can swing vertically to the horizontal, is hinged to one end (outer end) of the first guide rail 3 near the cabinet door 2. Each first guide rail 3 has a second guide rail 5 hinged to one end near the cabinet door 2, and the slider 11 can slide onto the horizontal second guide rail 5. Figure 3 As shown, the two second guide rails 5 are connected together by a laterally extending connecting rod 12 to ensure that the two guide rails can swing synchronously.

[0036] In this embodiment, the first guide rail 3 and the second guide rail 5 are hinged together. One movable leaf of the hinge is attached to the upper surface of the first guide rail 3, and the other movable leaf of the hinge is attached to the upper surface of the second guide rail 5.

[0037] To facilitate the sliding of slider 11 on the first guide rail 3 and the second guide rail 5, a first groove is provided on one side of the first guide rail 3, and a second groove is provided on the other side of the first guide rail 3; a third groove is provided on one side of the second guide rail 5, and a fourth groove is provided on the other side of the second guide rail 5. When the second guide rail 5 is in a horizontal state, slider 11 can slide from the first groove into the third groove, and from the second groove into the fourth groove.

[0038] The second guide rail 5 is provided with a support structure for supporting the second guide rail 5 in the horizontal direction, and the inner cavity is also provided with a locking structure for locking the second guide rail 5 in the vertical direction.

[0039] like Figure 3 As shown, the support structure includes a swing rod 6 connected to the side of the second guide rail 5 away from the first guide rail 3. The swing rod 6 is rotatably mounted on the second guide rail 5 to prevent it from hitting the cabinet door 2. When the second guide rail 5 is in a vertical state, the swing rod 6 is in a vertical state; when the second guide rail 5 is in a horizontal state, the swing rod 6 is in a vertical state with its lower end supported on the ground. A positioning structure is provided between the swing rod 6 and the second guide rail 5 to keep the swing rod 6 supported on the ground in its current state. Figure 3 As shown, there are two swing arms 6, which are respectively hinged to different second guide rails 5. The two swing arms 6 are symmetrically arranged to ensure the stability of the whole composed of the two second guide rails 5 and the connecting rod 12.

[0040] In other embodiments, without considering the internal cavity space, the support structure includes a strut fixed to the end of the second guide rail 5 away from the first guide rail 3. The strut is perpendicular to the second guide rail 5, and the second guide rail 5 is in a horizontal state when the lower end of the strut is supported on the ground. There are two struts, which are respectively fixed to different second guide rails 5. The two struts are symmetrically arranged to ensure the stability of the whole composed of the two second guide rails 5 and the connecting rod 12.

[0041] like Figure 4 and Figure 5 As shown, the positioning structure includes a guide hole on the side of the rocker arm 6 facing the second guide rail 5, a spring 7 and a ball bearing 8 inside the guide hole. The guide hole extends horizontally and is perpendicular to the second guide rail 5. A positioning cavity is provided on the side of the second guide rail 5 facing the rocker arm 6. When the second guide rail 5 is horizontal, the ball bearing 8 is positioned within the positioning cavity under the action of the spring 7. At this time, the rocker arm 6 is vertical, and the positioning cavity is located directly below the hinge point between the rocker arm 6 and the second guide rail 5. Specifically, one end of the spring 7 abuts against the inner end of the guide hole, and the other end acts on the ball bearing 8, providing a constant outward driving force for the ball bearing 8. During the rotation of the rocker arm 6, the guide hole is always blocked by the side of the second guide rail 5, preventing the ball bearing 8 and the spring 7 from coming out of the guide hole. The positioning cavity is hemispherical, and its depth is less than the radius of the ball bearing 8. The guide hole, spring 7, ball bearing 8, and positioning cavity ensure that the rocker arm 6 is in a vertically supported state, improving stability. When no support is needed, the swing arm 6 can disengage the ball bearing 8 from the positioning cavity, preventing the swing arm 6 from hitting the cabinet door 2 when the door is closed, thus preventing the cabinet door 2 from not closing securely.

[0042] like Figure 7 As shown, the locking structure includes a through hole 14 extending through the second guide rail 5, a positioning rod 9 slidably disposed within the through hole 14, and a positioning hole at the bottom of the inner cavity. When the second guide rail 5 is in a vertical state, the through hole 14 is directly above the positioning hole, and the lower end of the positioning rod 9 is inserted into the positioning hole to lock the second guide rail 5. The length of the positioning rod 9 is greater than the length of the through hole 14. When the lower end of the positioning rod 9 extends into the positioning hole, the upper end of the positioning rod 9 still protrudes from the upper end of the through hole 14. When the positioning rod 9 is inserted into the positioning hole, it can lock the second guide rail 5 in a vertical state, achieving the purpose of limiting the position of the base plate 4. Figure 7 As shown, each second guide rail 5 is provided with a through hole 14 and a positioning rod 9. The two positioning rods 9 are connected together by a crossbar 13 to ensure that the two positioning rods 9 can move synchronously.

[0043] like Figure 2 Figure 3As shown, a positioning block 10 is provided on the second guide rail 5. The inner end of the base plate 4, which is positioned on the first guide rail 3, abuts against the positioning block 10, and its outer end abuts against the second guide rail 5, which is in a vertical state. The positioning block 10 and the vertical second guide rail 5 are used to position the base plate 4.

[0044] Under normal conditions, the second guide rail 5 swings to a vertical position around its hinge point with the first guide rail 3 and is locked in a locked position by the locking structure, limiting the position of the base plate 4 and the equipment and preventing the base plate 4 from sliding on the first guide rail 3. When maintenance is required, the cabinet door 2 is opened and the locking structure is unlocked, allowing the second guide rail 5 to swing from a vertical position to a horizontal position. The second guide rail 5 is then supported by the support structure. At this time, the first guide rail 3 and the second guide rail 5 form a complete long guide rail, with the outer end of the long guide rail extending out of the inner cavity. The base plate 4 can slide along the first guide rail 3 onto the second guide rail 5, allowing the equipment mounted on the base plate 4 to be moved outside the cabinet 1 for easy maintenance.
