DETAILED DESCRIPTION

Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0035] Embodiment one

[0036] When the trailer type CT device shelter is moving, the influence of the external force caused by the bumping on the CT device in the shelter during the journey needs to be considered first, especially in the conditions of sharp turns, sudden stops and brakes, etc. For example, the centrifugal force in the process of sharp turns, the inertia in the case of brakes, and the influence caused by the bumping on the CT device are intensified, such as dislocation, collision and other problems of various electrical components in the CT device. Therefore, the following technical scheme is proposed:

[0037] Reference Figures 1-10 The trailer type CT device shelter in the embodiment comprises a shelter body 1, the lower side of the shelter body 1 is provided with a roller, and one end of the shelter body 1 is provided with a first warehouse 3 and a second warehouse 4 along the left-to-right direction, respectively. A CT device body 5 is arranged in the shelter body 1, a triangular connecting frame 9 is arranged at the lower side of the second warehouse 4, a cycloidal sleeve 10 is installed at the center point position of the inner wall bottom end of the second warehouse 4, a connecting ball 13 is arranged in the cycloidal sleeve 10, a vertical cycloidal cylinder 8 is installed at the upper end position of the cycloidal sleeve 10, the connecting ball 13 is installed at the center point position on the triangular connecting frame 9, a vertical cycloidal rod 16 is installed at the center point position of the connecting ball 13, a circular hole matched with the cycloidal rod 16 is formed at the upper end center point of the cycloidal sleeve 10, and the diameter of the circular hole is greater than the diameter of the cycloidal rod 16;

[0038] A multi-directional force receiving structure is arranged in the cycloidal cylinder 8, the multi-directional force receiving structure comprises a plurality of air column pipes 15, a directional sleeve 11 and a force receiving movable wheel 12, the force receiving movable wheel 12 is rotationally connected at the inner wall position of the directional sleeve 11, the directional sleeve 11 is installed on the circumferential outer wall of the cycloidal cylinder 8, and the plurality of air column pipes 15 are arranged in an annular array along the center point position of the cycloidal rod 16;

[0039] A directional telescopic connecting rod 6 is installed at the four corner positions in the first warehouse 3, one end of the directional telescopic connecting rod 6 is installed at the outer wall four corner position of the shelter body 1 close to the first warehouse 3, a connecting folding sleeve 2 is arranged between the first warehouse 3 and the shelter body 1, and a butt-jet protection structure is arranged between the first warehouse 3 and the shelter body 1;

[0040] The collision protection structure comprises a first hemispherical block 24 and a second hemispherical sleeve 25, and the first hemispherical block 24 and the second hemispherical sleeve 25 are provided with mounting discs 7 close to the cabin body 1 and the first-stage warehouse 3, and the two mounting discs 7 are respectively mounted on the cabin body 1 and the first-stage warehouse 3, and the first hemispherical block 24 and the second hemispherical sleeve 25 are symmetrically arranged.

[0041] Working principle: the cabin body 1, the first-stage warehouse 3 and the second-stage warehouse 4 in the overall structure are connected to the moving carrier through the triangular connecting frame 9, so that the moving carrier drags the cabin body 1 to move, and after moving to a specified area, the triangular connecting frame 9 is separated from the moving carrier, so that the cabin body 1, the first-stage warehouse 3 and the second-stage warehouse 4 are separated from the moving carrier, and the cabin body 1 is fixed. Here, no more will be described;

[0042] Here, the first-stage warehouse 3 and the second-stage warehouse 4 added between the cabin body 1 and the moving carrier are mainly described with reference to Figs. 2 and 3. Figure 4 and Figs. 4 and 5. Figure 8 Because the overall cabin body 1, the first-stage warehouse 3 and the second-stage warehouse 4 are not in a completely fixed connection state with the moving carrier, when the moving carrier moves, the centrifugal force generated in the sharp turn and the external force generated by inertia when the moving carrier stops will be directly or indirectly transmitted to the CT device body 5 in the cabin body 1, which will cause damage to the CT device body 5;

[0043] Therefore, in the implementation, the second-stage warehouse 4 is used to buffer the centrifugal force generated external force, and the first-stage warehouse 3 is used to buffer the external force generated by inertia. The two buffering modes mainly reflect the cycloidal motion of the cycloidal rod 16 and the collision motion between the first hemispherical block 24 and the second hemispherical sleeve 25.

[0044] Example two

[0045] This embodiment specifically introduces the multi-directional force structure in the example, and the specific introduction is as follows.

[0046] The top end of the cycloidal cylinder 8 is mounted on the top end of the inner wall of the second-stage warehouse 4, and the top end position of the cycloidal rod 16 is provided with an upper positioning cover 17, and the curved surface of the upper positioning cover 17 is matched with the top end of the inner wall of the cycloidal cylinder 8.

[0047] The gas column pipe 15 is provided with two first piston rods 21 and a second piston rod 22, respectively, and one end of the second piston rod 22 is directed to the cycloidal rod 16, and an inner force receiving piece 20 is mounted on the one end position of the second piston rod 22.

[0048] One end of the first piston rod 21 is directed to the force receiving movable wheel 12, and a clamping taper block 18 is mounted on the one end position of the first piston rod 21, and the second piston rod 22 is provided with a top spring 23 at the position of the circular circumferential outer wall of the gas column pipe 15 and the inner force receiving piece 20.

[0049] The inner ring position of the force-acting movable wheel 12 is provided with a force-acting clamping block 14, the contour line of the force-acting clamping block 14 is matched with the outer contour of the clamping taper block 18, and the blocking block 19 is installed at the position corresponding to the plurality of inner force-acting pieces 20 of the pendulum rod 16.

[0050] The purpose is that in the initial state, the connecting ball 13 drives the pendulum rod 16 to be in a vertical upward state, and then the blocking block 19 on the pendulum rod 16 does not contact the inner force-acting piece 20, so that each air column pipe 15 inside is in a relatively stable state;

[0051] When encountering a sharp turn, the connecting ball 13 at this time is driven by the centrifugal force to make the pendulum rod 16 perform a cycloid motion with the center point of the connecting ball 13 as the center, and when the pendulum rod 16 performs the cycloid motion, the blocking block 19 at this time will touch the inner force-acting piece 20, thereby pushing the second piston rod 22 to move to the force-acting movable wheel 12, and under the action of air pressure, the first piston rod 21 will also move to the force-acting movable wheel 12;

[0052] When the first movable rod 21 moves, referring to Figure 7 The clamping taper block 18 at the corresponding position pushes against the force-acting clamping block 14, and the contour of the clamping taper block 18 and the force-acting clamping block 14 becomes a force point, thereby indirectly transmitting the horizontal thrust on the first piston rod 21 to the force-acting movable wheel 12, thereby driving the force-acting movable wheel 12 to rotate in a small range;

[0053] The above process mainly includes: the lateral force generated by the inner force-acting piece 20 under the action of centrifugal force - the lateral force is transmitted to the clamping taper block 18 through the second movable rod 22 and the first piston rod 21 - the lateral force is transmitted to the force-acting clamping block 14 through the clamping taper block 18, and finally the lateral force is converted into a rotating force, thereby "consumes" the centrifugal force generated in the process of sharp turning, so as to reduce the influence of the centrifugal force on the cabin 1.

[0054] Embodiment three

[0055] This embodiment specifically introduces the hedging protection structure in embodiment one, which is as follows:

[0056] The outer wall of the side where the first half block 24 and the second half block 25 are close to each other is provided with a plurality of stacked arc steel sheets 28, the plurality of stacked arc steel sheets 28 are arranged in a ring shape along the center point of the first half block 24 and the second half block 25, and the cross section of the stacked arc steel sheet 28 is curved and arched outward.

[0057] The outer wall center point position of the first half block 24 close to the second half block 25 is provided with a horizontally arranged clamping rod 26, two clamping grooves 27 are formed in the circumferential outer wall of the clamping rod 26, the two clamping grooves 27 are symmetrically arranged, and a clamping hole matched with the clamping rod 26 is formed in the center point position of the second half block 25.

[0058] The second half block 25 is rotatably installed with a movable gear 29 at the inner position corresponding to the card hole, the inner circle diameter of the movable gear 29 is equal to the outer diameter of the card rod 26, and the inner circle position of the movable gear 29 is installed with a card block 30 matched with the card slot 27;

[0059] A servo motor 31 is installed at the inner bottom end position of the secondary bin 4, the output end of the servo motor 31 is installed with a driving gear 32, the driving gear 32 is engaged with the movable gear 29, and the second half block 25 is provided with a missing slot matched with the driving gear 32.

[0060] The purpose is to refer to the attached Figure 8 、 9 When the cabin 1 is suddenly stopped, the external force generated by inertia will drive the first half block 24 to move to the second half block 25, so that the first half block 24 and the second half block 25 are close to each other, and the plurality of laminated arc steel sheets 28 between them are correspondingly bent, which is to store the kinetic energy generated by inertia;

[0061] When storing kinetic energy, that is, the card rod 26 is inserted in the first half block 25, in this process, the servo motor 31 is started to drive the driving gear 32 to rotate in a small range, and the movable gear 29 is rotated synchronously, so that the card block 30 in the movable gear 29 is clamped in the card slot 27 of the card rod 26, the purpose of this mode is to delay the release of the kinetic energy stored in the plurality of laminated arc steel sheets 28 when the first half block 24 is inserted into the second half block 25, to avoid the influence of the reaction force generated by the rebound force of the laminated arc steel sheet 28 on the cabin 1;

[0062] When the kinetic energy needs to be released, the servo motor 31 needs to be rotated again when the moving carrier migrates the whole cabin 1, so that the card block 30 in the movable gear 29 is separated from the card slot 27, so as to slowly release the kinetic energy stored in the laminated arc steel sheet 28.

[0063] In summary: the CT shelter structure is adopted by separation and dragging, and the first bin and the secondary bin are respectively arranged at one end of the cabin, the secondary bin is used to buffer the centrifugal force generated by the cabin during transportation because of the sharp turn, which is specifically reflected in the mutual cooperation between the connecting ball and the cycloid rod, when the cycloid rod is freely inclined due to the action of the centrifugal force, the side external force is generated, the side external force acts in the air column pipe, combined with the principle of air pressure transmission, the side external force is transmitted to the stressed movable wheel, and the stressed movable wheel is driven to rotate in a small range by the side external force, so as to "eliminate" the influence of the centrifugal force on the whole cabin.
