Description

Technical Field

[0001] This invention relates to the field of automatic control technology, and in particular to a transport vehicle and a vehicle-mounted X-ray system. Background Technology

[0002] Transportation refers to the logistics activities of moving goods from one place to another using specific equipment and tools. It involves the spatial displacement of goods within different geographical areas with the aim of changing their spatial location.

[0003] During the transportation of mobile equipment, such as X-ray inspection equipment, the equipment is easily subjected to severe vibrations due to the shaking of the vehicle body. Some precision equipment is extremely sensitive to environmental vibrations; even small vibrations can seriously affect measurement accuracy or even damage the equipment itself. Long-term vibration can cause resonance in various parts, leading to screws or nuts coming loose, thus affecting the normal use of the equipment. Summary of the Invention

[0004] Therefore, it is necessary to provide a vehicle-mounted X-ray system that solves the problem of mobile devices being prone to shaking during transportation.

[0005] A transport vehicle, comprising:

[0006] The carriage has at least two first limiting mechanisms and at least one second limiting mechanism spaced apart on its bottom surface; at least one second limiting mechanism can be selectively connected to a first side of the transported equipment; at least two first limiting mechanisms can be selectively connected to a second side and a third side of the transported equipment, respectively; the second side and the third side are both adjacent to the first side, and the first side, the second side, and the third side are all located on the circumferential side of the transported equipment formed with the vertical direction as the axis;

[0007] The first limiting mechanism is rotatably or movably connected to the bottom surface of the carriage. The first limiting mechanism has a locking position connected to the transported equipment and an unlocking position disconnected from the transported equipment.

[0008] In one embodiment, the first limiting mechanism includes a first limiting member and a second limiting member. One end of the second limiting member is rotatably or movably connected to the bottom surface of the carriage, and the other end of the second limiting member is provided with a limiting hole. The first limiting member is movably connected to the limiting hole.

[0009] In one embodiment, the first limiting member is threadedly connected to the limiting hole, and the position where the transported device is connected to the first limiting member has a first connecting portion, the first connecting portion being a recessed structure, and the first limiting member having a mating portion that engages with the recessed structure; the second limiting member is rotated or moved to bring the first limiting member closer to the transported device, and the first limiting member is rotated to insert the mating portion into the recessed structure, so that the first limiting mechanism is in the locked position.

[0010] In one embodiment, the first limiting mechanism further includes a locking component connected to the second limiting member for limiting the rotation of the first limiting member relative to the second limiting member.

[0011] In one embodiment, the locking component includes a first locking member that is slidably disposed on the second limiting member. The first limiting member has a first slot at one end away from the mating part. The first locking member can selectively engage with the first slot to restrict the rotation of the first limiting member.

[0012] In one embodiment, the first locking member has a first annular groove and a second annular groove on its circumferential surface, which are spaced apart axially; the locking assembly further includes at least one locking roller, which is disposed on the second limiting member and abuts against the circumferential outer side of the first locking member, and can cooperate with the first annular groove and the second annular groove to restrict the movement of the first locking member.

[0013] In one embodiment, the locking assembly further includes a locking elastic element connected between the locking roller and the second limiting member, so that the locking roller abuts against the first locking member.

[0014] In one embodiment, there are multiple first slots, the first limiting member is cylindrical, and the multiple first slots are spaced apart along the circumferential side of the first limiting member.

[0015] In one embodiment, the carriage is provided with a guiding mechanism for guiding the transported equipment to a fixed position.

[0016] In one embodiment, the second limiting mechanism includes a first limiting plate and a second limiting plate connected to the first limiting plate. The second limiting plate extends horizontally relative to the first limiting plate. The first limiting plate and the second limiting plate are used to connect with the transported equipment to restrict the movement of the transported equipment.

[0017] A vehicle-mounted X-ray system, characterized in that it includes a vehicle-mounted X-ray detection device and a transport vehicle as described above, wherein the vehicle-mounted X-ray detection device is detachably connected to the vehicle compartment.

[0018] This technical solution has the following beneficial effects: The transport vehicle is equipped with at least two first limiting mechanisms and at least one second limiting mechanism inside its compartment. Each first limiting mechanism has a locked position and an unlocked position. When the first limiting mechanism is in the locked position, it connects to the transported equipment, restricting its movement. When the first limiting mechanism is in the unlocked position, it disconnects from the transported equipment, thus releasing the restriction on its movement. When it is necessary to secure the transported equipment inside the compartment, the first limiting mechanism is moved from the unlocked position to the locked position. The first and second limiting mechanisms work together to limit the transported equipment, reducing the possibility of it shifting. When it is necessary to remove the transported equipment from the compartment, the first limiting mechanism is moved to the unlocked position, disengaging it from the transported equipment. The first limiting mechanism no longer restricts the movement of the transported equipment, thus releasing the restriction. The cooperation of the two limiting mechanisms improves the stability during transport and enables rapid unlocking, making both securing and unlocking operations simpler and more convenient.

Detailed Implementation

[0025] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0031] like Figure 1 As shown, an embodiment of the present invention provides a transport vehicle 100, including a carriage 101. At least two first limiting mechanisms 110 and at least one second limiting mechanism 140 are spaced apart on the bottom surface of the carriage 101. At least one second limiting mechanism 140 can be selectively connected to a first side of a transported device 200. At least two first limiting mechanisms 110 can be selectively connected to a second side and a third side of the transported device 200, respectively. The second side and the third side are adjacent to the first side, and the first side, the second side and the third side are all located on the circumferential side of the transported device 200 with the vertical direction as the axis. The first limiting mechanism 110 is rotatably or movably connected to the bottom surface of the carriage 101, and the first limiting mechanism 110 has a locking position connected to the transported device 200 and an unlocking position disconnected from the transported device 200.

[0032] like Figure 1As shown, in a practical application scenario, there is one second limiting mechanism 140, which abuts against the left side of the transported equipment 200. There are two first limiting mechanisms 110, which are respectively connected to the two sides of the transported equipment 200 adjacent to its left side, namely the front and rear sides. One first limiting mechanism 110 is connected to the front side of the transported equipment 200, and the other is connected to the rear side. The connection position of the first limiting mechanism 110 to the transported equipment 200 is far from the connection position of the second limiting mechanism 140 to the transported equipment 200. By setting multiple connection positions on the horizontal circumference of the transported equipment 200, and by having a large distance between the multiple connection positions, the overall fixing effect and stability of the transported equipment 200 are improved. When it is necessary to fix the transported equipment 200 inside the carriage 101, the transported equipment 200 is first moved so that the first side... Figure 1 The left side of the device 200 abuts against the second limiting mechanism 140. Then, the first limiting mechanism 110 is moved from the unlocked position to the locked position, so that the two first limiting mechanisms 110 are respectively connected to the front and rear sides of the transported device 200. By cooperating with the first limiting mechanism 110 and the second limiting mechanism 140, the movement of the transported device 200 along the horizontal plane (i.e., the XY plane in the figure) and the vertical direction (i.e., the Z direction in the figure) is limited. By limiting the movement of the transported device 200 in three directions, the possibility of the entire transported device 200 shifting during transportation is reduced.

[0033] When the transported equipment 200 needs to be removed from the carriage 101, the first limiting mechanism 110 is moved to the unlocked position, disengaging from the transported equipment 200. The first limiting mechanism 110 no longer restricts the movement of the transported equipment 200, allowing it to move from its current position and thus releasing the restriction on it. The cooperation of the two limiting mechanisms improves the stability during transport and enables rapid unlocking, making both fixing and unlocking operations simpler and more convenient. The transported equipment 200 can be a vehicle-mounted X-ray device used in the medical field, such as a vehicle-mounted CT scanner, or other large mobile devices such as cars and tanks.

[0034] like Figure 2As shown, in one embodiment, the first limiting mechanism 110 includes a first limiting member 111 and a second limiting member 112. One end of the second limiting member 112 is rotatably or movably connected to the bottom surface of the carriage 101, and the other end of the second limiting member 112 is configured with a limiting hole 1121. The first limiting member 111 is movably connected in the limiting hole 1121. Thus, when it is necessary to limit and fix the transported equipment 200, the second limiting member 112 is first moved or rotated to be close to the transported equipment 200, and then the first limiting member 111 is connected to the first connecting part 210 through the connection and cooperation between the first limiting member 111 and the limiting hole 1121. Without changing the position of the first limiting member 111, the first connecting part 210 will not move, thereby restricting the movement of the transported equipment 200.

[0035] like Figure 2 As shown, in a specific embodiment, the first limiting member 111 is threadedly connected to the limiting hole 1121. The position where the transported device 200 connects to the first limiting member 111 has a first connecting portion 210, which has a recessed structure. The first limiting member 111 has a mating portion that engages with the recessed structure. The second limiting member 112 rotates or moves to bring the first limiting member 111 closer to the transported device 200. Rotating the first limiting member 111 causes the mating portion to insert into the recessed structure, thus locking the first limiting mechanism 110 in the locked position. In other words, the first limiting member 111 and the second limiting member 112 are threadedly engaged. Thus, when the position of the second limiting member 112 is fixed, the first limiting member 111 can reciprocate within the limiting hole 1121 while rotating around its own axis, until the first limiting member 111 moves to engage with the recessed structure, at which point the first limiting mechanism 110 restricts the movement of the transported device 200. When it is necessary to unlock, simply rotate the first limit member in the opposite direction to disengage it from the recessed structure.

[0036] Specifically, the mating part of the first limiting member 111 is a snap-fit ​​shaft, and the first connecting part 210 can be a roller. The recessed structure is a snap-fit ​​hole provided in the inner ring of the roller. The snap-fit ​​shaft and the snap-fit ​​hole engage to restrict the movement of the first limiting member 111. Furthermore, a first handwheel 115 is connected to the end of the first limiting member 111. During operation, rotating the first handwheel 115 will drive the first limiting member 111 to rotate synchronously, realizing the helical feeding of the first limiting member 111, thereby connecting or disconnecting it from the recessed structure.

[0037] like Figure 2As shown, in one specific embodiment, the bottom of the second limiting member 112 is hinged to the hinge seat 117 on the bottom surface of the carriage 101. Thus, when the first limiting member 111 is in the unlocked position, that is, when the mating part of the first limiting member 111 is disengaged from the recessed structure, the second limiting member 112 can be rotated 90 degrees clockwise, that is, the axes of the first limiting member 111 and the second limiting member 112 are parallel to the Z direction, thereby releasing the movement restriction of the transported equipment 200 and moving the transported equipment to another position. When it is necessary to limit the transported equipment 200, the second limiting member 112 is operated to rotate counterclockwise by 90 degrees, that is, the axes of the first limiting member 111 and the second limiting member 112 are parallel to the Y direction. The first limiting member 111 cooperates with the recessed structure to restrict vertical movement, and the second limiting member 112 abuts against the first connecting part 210 to restrict the movement of the transported equipment 200, thereby locking the transported equipment 200.

[0038] In another embodiment, a second locking member is provided on the side of the second limiting member facing away from the transported equipment. When the first limiting mechanism is in the locked position, the second locking member drives the second limiting member to press against the transported equipment. The action of the second locking member reduces the possibility of the second limiting member loosening. Since the first limiting member is connected to the second limiting member, the possibility of the first limiting member loosening is also reduced, thereby ensuring the connection stability between the first limiting member and the transported equipment and guaranteeing the fixation effect on the transported equipment.

[0039] Specifically, a fixing member is provided on the bottom surface of the carriage, with the fixing member spaced apart from the hinge seat. The second locking member is an elastic member, which connects the second limiting member and the hinge seat. When the first limiting mechanism is in the unlocked position, the second limiting member is fixed by the fixing member, and the elastic member is in a compressed state. When it is necessary to switch the first limiting mechanism to the locked state, the second limiting member is disengaged from the fixing member. Under the reset action of the elastic member, the second limiting member rotates counterclockwise until it abuts against the transported equipment; and under the action of the elastic member, the second limiting member is tightly attached to the transported equipment, reducing the possibility of loosening of the second and first limiting members, thereby ensuring the stability of the first limiting member's fixation to the transported equipment. The elastic member can specifically be a torsion spring.

[0040] In other embodiments, the first limiting mechanism includes a first limiting member, and the position on the transported equipment where it connects to the first limiting member has a first connecting portion. The first connecting portion is a recessed structure with internal threads, and the first limiting member can thread-fit with the recessed structure. When the first limiting member rotates to the point of thread-fitting with the recessed structure, the first limiting mechanism is in a locked position, restricting the movement of the transported equipment during transportation.

[0041] like Figure 2As shown, in one embodiment, the first limiting mechanism 110 further includes a locking component connected to the second limiting member 112, used to restrict the rotation of the first limiting member 111 relative to the second limiting member 112. When the first limiting mechanism 110 is in the locked position, the locking component is connected to the first limiting member 111 to restrict the rotation of the first limiting member 111, thereby reducing the risk of the first limiting member 111 accidentally rotating out of the limiting hole 1121 and ensuring the reliability of the connection between the first limiting member 111 and the first connecting portion 210.

[0042] like Figure 2 and Figure 3 As shown, specifically, the locking assembly includes a first locking member 113, which is slidably disposed on the second limiting member 112. The end of the first limiting member 111 away from the mating portion is provided with a first slot 1111. The first locking member 113 can selectively engage with the first slot 1111, thereby restricting the rotation of the first limiting member 111. When the first limiting member 111 engages with the recessed structure of the transported equipment 200, the first locking member 113 engages with the first slot 1111. Since the first locking member 113 is slidably connected to the second limiting member 112, the first locking member 113 will not rotate relative to the second limiting member 112. Therefore, when the first locking member 113 extends into the first slot 1111 of the first limiting member 111, the possibility of accidental rotation of the first limiting member 111 is reduced, ensuring the reliability of the first limiting mechanism 110 in the locked position, and thus ensuring the reliability of the limiting of the transported equipment 200. When the first locking member 113 disengages from the first slot 1111, it no longer restricts the rotation of the first limiting member 111.

[0043] like Figure 3 As shown, the end of the first locking member 113 is further connected to a second handwheel 116. During operation, directly applying the second handwheel 116 will drive the first locking member 113 to move along the Z direction, thereby connecting or disconnecting the first locking member 113 from the first slot 1111. The second handwheel 116 increases the contact area, making it easier for the operator to move the first locking member 113.

[0044] like Figure 2 and Figure 3As shown, in one embodiment, the first locking member 113 has a first annular groove 1131 and a second annular groove 1132 on its circumferential surface. The first annular groove 1131 and the second annular groove 1132 are spaced apart along the axial direction (i.e., the Z direction in the figure) of the first locking member 113. The locking assembly also includes a locking seat 114 connected to the second limiting member 112. At least one locking roller 1141 is slidably disposed in the locking seat 114. The locking roller 1141 abuts against the circumferential outer side of the first locking member 113 and can cooperate with the first annular groove 1131 and the second annular groove 1132 to restrict the movement of the first locking member 113.

[0045] Specifically, such as Figure 3 As shown, when the first locking member 113 engages with the first slot 1111, the locking roller 1141 engages with the upper first annular groove 1131; when the first locking member 113 disengages from the first slot 1111, the locking roller 1141 engages with the lower second annular groove 1132. When the locking roller 1141 engages with either the first annular groove 1131 or the second annular groove 1132, if it is necessary to move the first locking member 113 up or down, the force needs to be increased to disengage the locking roller 1141 from the annular groove. The engagement of the locking roller 1141 with the annular groove serves as a gear position indicator, facilitating the operator to raise or lower the first locking member 113 to the appropriate height.

[0046] like Figure 3 As shown, in one embodiment, the locking component further includes a locking elastic element 1142, which is connected between the locking roller 1141 and the second limiting member 112, so that the locking roller 1141 abuts against the first locking member 113. When the locking roller 1141 disengages from the first annular groove 1131 or the second annular groove 1132, the locking elastic element 1142 is further compressed until the locking roller 1141 moves to engage with the other annular groove, and the compression of the locking elastic element 1142 is restored. By providing the locking elastic element 1142, the locking roller 1141 is pressed against the first locking member 113, reducing the possibility of accidental slippage of the first locking member 113 and ensuring the reliability of locking the first limiting member.

[0047] like Figure 3As shown, in one embodiment, there are multiple first slots 1111, and the first limiting member 111 is cylindrical. The multiple first slots 1111 are spaced apart along the circumferential side of the first limiting member 111. By providing multiple first slots 1111, the first limiting member 111 can be adapted to different rotation angles. This ensures that when the first limiting member 111 rotates to engage with the recessed structure, the first locking member 113 can engage with the first slot 1111, thereby limiting the rotation of the first limiting member 111 and improving the locking reliability and usability of the first limiting mechanism.

[0048] like Figure 4 As shown, in one embodiment, the second limiting mechanism 140 includes a first limiting plate 141 and a second limiting plate 142 connected to the first limiting plate 141. The second limiting plate 142 extends relative to the first limiting plate 141 in the X direction. The first limiting plate 141 and the second limiting plate 142 are used to connect with the transported device 200 to restrict the movement of the transported device 200. Specifically, the position where the transported device connects with the second limiting mechanism has a second connecting portion 220. The first limiting plate 141 has an abutting surface extending in the Z direction. When the first limiting plate 141 abuts against the second connecting portion 220, the movement of the transported device 200 in the X direction can be restricted by the abutting surface. When the second limiting plate 142 abuts against the second connecting portion 220, it can restrict the movement of the transported equipment 200 along the Z direction. Through the abutment and limiting action of the first limiting plate 141 and the second limiting plate 142, the possibility of the transported equipment 200 shifting is reduced, improving the stability of the transported equipment 200 during transportation. Furthermore, a buffer member 143 is provided on the right side of the first limiting plate 141 near the transported equipment 200. By providing the buffer member 143 between the first limiting plate 141 and the transported equipment 200, noise reduction and buffering are achieved. The buffer member 143 can be a flexible component such as a spring or rubber. The second connecting portion 220 can be a roller.

[0049] like Figure 5 As shown, in one embodiment, a guiding mechanism is provided inside the carriage 101 to guide the transported equipment 200 to a fixed position. Specifically, the guiding mechanism includes a first guiding part 151 and a second guiding part 152, both extending along the X direction. The two guiding parts guide the movement of the transported equipment 200 along the X direction, causing the transported equipment 200 to move until one end abuts against the first limiting mechanism 110 and the other end abuts against the second limiting mechanism 140, thereby activating the first locking member to limit the transported equipment to its current position. The two guiding parts can specifically be guide rails.

[0050] Furthermore, the present invention also provides a vehicle-mounted X-ray system 10, including a vehicle-mounted X-ray detection device and the aforementioned transport vehicle 100, wherein the vehicle-mounted X-ray detection device is detachably connected to the vehicle compartment 101. Because the vehicle-mounted X-ray system 10 has the aforementioned transport vehicle 100, when it is necessary to fix the vehicle-mounted X-ray detection device inside the vehicle compartment 101, the first limiting mechanism 110 is operated to move from the unlocked position to the locked position. The first limiting mechanism 110 and the second limiting mechanism 140 cooperate to limit the movement of the vehicle-mounted X-ray detection device, reducing the possibility of movement of the entire vehicle-mounted X-ray detection device. When it is necessary to remove the vehicle-mounted X-ray detection device from the vehicle compartment 101, the first limiting mechanism 110 is operated to move to the unlocked position, causing the first limiting mechanism 110 to disengage from the vehicle-mounted X-ray detection device. The first limiting mechanism 110 no longer restricts the movement of the vehicle-mounted X-ray detection device, thereby releasing the restriction on the vehicle-mounted X-ray detection device. The combination of two limiting mechanisms improves the stability during transportation and enables quick unlocking, making fixing and unlocking operations simpler and more convenient.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
