DETAILED DESCRIPTION

[0061] The present application will be further described in detail below with reference to the accompanying drawings. Figure 1 - the accompanying drawings, Figure 8 , and the specific embodiments.

[0062] A child-mother connection vehicle, with reference to Figure 1 , 2, including the mother car 1, the child car 3, the sliding frame 4, the unhooking a2, the rotating mechanism a3 and the air cooling mechanism a8; The mother car 1 is movably arranged on the track, that is, the mother car 1 is provided with a top plate 2, and the four corners of the lower end of the top plate 2 are provided with moving wheels, which are in rolling connection with the track; The plate surface of the top plate 2 is rectangular, and the air cooling mechanism a8 is installed at the center of the plate surface of the top plate 2; Each group of child cars 3 is arranged on both sides of the air cooling mechanism a8 on the top plate 2, and each group of child cars 3 moves along the width direction of the top plate 2; The sliding frame 4 is installed on the child car 3 and moves synchronously with the child car 3; The air cooling mechanism a8 is used for dragging the two child cars 3 on the top plate 2 to blow and cool; The gear is installed on the child car 3, and the rack is arranged on the top plate 2 along the width direction of the top plate 2 and engaged with the gear; The gear is driven to rotate by the motor, so that the child car 3 can normally drive the sliding frame 4 to move along the width direction of the top plate 2; The unhooking a2 is installed at the front end of the sliding frame 4, and is used for inserting and cooperating with the connecting groove on the heating barrel; After the unhooking a2 is inserted into the connecting groove, it can be connected with the connecting groove by self-rotation. The rotating mechanism a3 is installed on the sliding frame 4, and the rotating mechanism a3 is used for driving the unhooking a2 to rotate on the sliding frame 4.

[0063] When the heating barrel needs to be connected with the unhooking a2, the mother car 1 is directly moved close to the heating barrel, then the child car 3 is moved, so that the unhooking a2 is inserted into the connecting groove of the heating barrel, then the rotating mechanism a3 is started, so that the unhooking a2 rotates in the connecting groove, thereby realizing the connection between the unhooking a2 and the connecting groove; At this time, the child car 3 can drag the heating barrel to the top plate 2 of the mother car 1, without the need for workers to manually connect close to realize the transfer of the heating barrel, so as to achieve the effect of convenient transfer of the heating barrel; The air cooling mechanism a8 arranged on the top plate 2 can cool the heating barrel in time, so as to reduce the temperature of the heating barrel as soon as possible, thereby avoiding the damage of the power source on the child car 3 and the mother car 1 caused by high temperature to a certain extent.

[0064] Combination Figure 3 , 4The unhooking a2 comprises a rotating shaft a21 and a clamping block a22. The mounting seat a4 is arranged on the sliding frame 4, the rolling bearing a41 is arranged in the mounting seat a4 in a rotating mode, the rotating shaft a21 passes through the rolling bearing a41 and is in interference fit with the inner ring of the rolling bearing a41, so that the rotating shaft a21 is installed on the sliding frame 4 in a horizontal rotating mode, and the length direction of the rotating shaft a21 is parallel to the moving direction of the sub-car 3. The clamping block a22 is installed at the end of the rotating shaft a21, the length direction of the clamping block a22 is perpendicular to the length direction of the rotating shaft a21, that is, the clamping block a22 and the rotating shaft a21 form a T-shaped structure. The opening shape of the connecting groove arranged on the side wall of the heating barrel corresponds to the end surface shape of the clamping block a22, and the inner abutting groove is arranged on the inner wall of the connecting groove and is used for abutting against the clamping block a22 after rotation. In this embodiment, when the clamping block a22 is inserted into the connecting groove in a perpendicular mode, the clamping block a22 is rotated by 90°, so that the two ends of the clamping block a22 are located in the inner abutting groove, so that the clamping block a22 cannot be withdrawn from the direction perpendicular to the opening of the connecting groove, and the connecting effect of the clamping block a22 and the connecting groove on the heating barrel is achieved.

[0065] As shown in Figure 3 、 4 , the rotating mechanism a3 comprises a driving rotating component a5 and a driven rotating component a6. The driven rotating component a6 is installed at the end of the rotating shaft a21 away from the clamping block a22. The driving rotating component a5 is installed on the sliding frame 4 and is used for driving the driven rotating component a6 to rotate, so that the driven rotating component a6 drives the rotating shaft a21 to rotate after rotation, and the clamping block a22 inserted into the connecting groove is rotated, so that the two ends of the clamping block a22 are finally located in the inner abutting groove, and the connecting effect of the unhooking a2 and the heating barrel is achieved. It is worth noting that the rotating mechanism a3 is divided into the driving rotating component a5 and the driven rotating component a6, which is essentially a separate design. The rotating mechanism a3 is divided into two parts that can be separated. If any one of the driving rotating component a5 or the driven rotating component a6 is damaged, the damaged part needs to be replaced, which greatly reduces the replacement cost. Moreover, the design can make the driving rotating component a5 away from the heating barrel, so as to reduce the probability of failure of the driving rotating component a5 caused by high temperature.

[0066] As shown in Figure 4 、 5As shown, specifically, the active rotation assembly a5 includes an electric push rod a51, a rotation lever a52, and a connecting rod a53; the rod body of the electric push rod a51 is hinged to the sliding frame 4; multiple linear bearings are also installed on the sliding frame 4, with the central axes of the multiple linear bearings on the same straight line, the rotation lever a52 passes through the multiple linear bearings in sequence, the rotation lever a52 is interference-fitted with the inner ring of the linear bearing, the central axis of the rotation lever a52 is on the same straight line as the central axis of the rotation shaft a21, and the length direction of the rotation lever a52 is perpendicular to the length direction of the piston rod of the electric push rod a51; one end of the connecting rod a53 is vertically fixed to the side wall of the rotation lever a52 near the end, and the other end is hinged to the piston rod of the electric push rod a51.

[0067] Reference Figure 4 , 5 The driven rotating assembly a6 includes a rotating disk a61 and a rotating support rod a62. The rotating disk a61 is coaxially mounted on the end of the rotating shaft a21 away from the locking block a22, while the rotating support rod a62 is vertically mounted on the disk surface of the rotating disk a61. A lever a521 is provided at the end of the rotating lever a52 near the rotating support rod a62, and the lever a521 is used to abut against the rotating support rod a62.

[0068] After activating the electric actuator a51, the piston rod of the electric actuator a51 extends. The extended piston rod of the electric actuator a51 pushes the connecting rod a53 to rotate around the end center of the rotating lever a52, thereby driving the rotating lever a52 to rotate. After the rotating lever a52 rotates, it drives the lever a521 to move circumferentially around the center of the rotating disk a61, which in turn causes the lever a521 to abut against the rotating support rod a62 and pushes the rotating support rod a62 to move circumferentially around the center of the rotating disk a61. Finally, the rotating disk a61 drives the rotating shaft a21 to rotate, allowing the locking block a22 to rotate within the connecting groove. It is worth noting that in this application, combined with Figure 6 When the piston rod of the electric push rod a51 extends to its maximum length, it can rotate the rotating disk a61 by 90°, which just meets the requirement that the snap-fit ​​block a22 inserted into the connecting slot rotates by 90°.

[0069] Reference Figure 3 , 4, the elastic reset assembly a7 is arranged between the rotating support rod a62 and the sliding frame 4, and is used for resetting the rotating disc a61 to the initial state before rotation. Specifically, the elastic reset assembly a7 comprises an adjusting screw rod a71 and a tension spring a72, the adjusting screw rod a71 is threadedly arranged on the sliding frame 4, and one end of the tension spring a72 is connected with the rotating support rod a62 and the other end is connected with the adjusting screw rod a71. When the clamping block a22 is opposite to the opening of the connecting groove, the tension spring a72 is in a natural state. Figure 5 、 6 When the clamping block a22 is opposite to the opening of the connecting groove and is inserted, the rotating support rod a62 is pushed by the pushing block a521 to rotate the rotating disc a61 by 90°, and the tension spring a72 is also stretched to be in a taut state. At this time, the two ends of the clamping block a22 are in the inner abutting grooves, so that the heating barrel and the hook a2 are connected smoothly. Then, the heating barrel is pulled to the sub vehicle 3 for transfer, and after being transferred to the destination, the piston rod of the electric push rod a51 is retracted, so that the pushing block a521 no longer abuts against the rotating support rod a62. At this time, the tension spring a72 is retracted under the action of the elastic force of the tension spring a72, and the rotating disc a61 is pulled back to the original state. The clamping block a22 is also rotated by 90° and is separated from the inner abutting grooves, so that the clamping block a22 is in the state of being opposite to the opening of the connecting groove. At this time, the hook a2 and the heating barrel can be separated smoothly, and the effect that the hook a2 is connected and separated from the heating barrel conveniently is achieved.

[0070] As shown in Figure 1 、 2 , the air cooling mechanism a8 comprises an air cooling frame a81 and fans a82. The air cooling frame a81 is arranged at the middle part of the top plate 2, and the fans a82 are arranged on the air cooling frame a81 and are provided in plurality. The plurality of fans a82 respectively blow cold air to the two sides of the air cooling frame a81. When the two groups of sub vehicles 3 pull the two heating barrels to the top plate 2, the fans a82 can cool the heating barrels in time, so that the sub vehicles 3 and the power source on the mother vehicle 1 are also prevented from being damaged by high temperature to a certain extent.

[0071] Combining Figure 7 、 8The mobile anti-swing structure is arranged between the child vehicle 3 and the parent vehicle 1, and comprises a directional rail b1, a rolling abutting mechanism b2 and a rolling guiding mechanism b6. The directional rail b1 is installed on the top plate 2 of the parent vehicle 1, and the length direction of the directional rail b1 is consistent with the width direction of the top plate 2 of the parent vehicle 1. Two groups of the directional rail b1 are arranged in parallel on the top plate 2 of the parent vehicle 1, and a cavity is left between the two groups of the directional rail b1. The rolling abutting mechanism b2 is installed on the sliding frame 4 of the child vehicle 3 and is located in the cavity. The rolling abutting mechanism b2 is used for rolling abutting and cooperating with the inner rail wall of one group of the directional rail b1 located in the cavity. The rolling guiding mechanism b6 is also installed on the sliding frame 4 of the child vehicle 3 and is used for rolling and cooperating with the inner rail wall of the other group of the directional rail b1 located in the cavity.

[0072] The rolling abutting mechanism b2 and the rolling guiding mechanism b6 respectively abut against the inner rail wall of one group of the directional rail b1 in the cavity between the two groups of the directional rail b1 and move away from each other, so that the sliding frame 4 of the child vehicle 3 is not easy to deviate when moving along the width direction of the parent vehicle 1. In addition, the child vehicle 3 is not easy to swing left and right when dragging and transporting objects under the guidance and limiting action of the two groups of the directional rail b1, and the sliding frame 4 of the child vehicle 3 can stably move along the length direction of the directional rail b1 on the parent vehicle 1. It is worth noting that when installing the application, the rolling abutting mechanism b2 needs to be installed first, that is, the rolling abutting mechanism b2 is rolling abutting and cooperating with the inner rail wall of one group of the directional rail b1, and then the rolling guiding mechanism b6 is installed. After being installed in this order, the rolling abutting mechanism b2 and the rolling guiding mechanism b6 can be ensured to be in contact with the inner rail wall of the directional rail b1, and the rolling abutting mechanism b2 itself has abutting force, which can ensure that the rolling abutting mechanism b2 is always in contact with the inner rail wall of one group of the directional rail b1, and the guiding stability of the whole child vehicle 3 during movement is further improved.

[0073] In combination Figure 7 , 8 The rolling abutting mechanism b2 comprises a main shaft b3, a rolling assembly b4 and an elastic abutting assembly b5. The main shaft b3 is vertically installed on the sliding frame 4 of the child vehicle 3 and vertically extends downward into the cavity between the two groups of the directional rail b1. The rolling assembly b4 is rotationally arranged on the main shaft b3 at one end located in the cavity and is mainly used for rolling and contacting the inner rail wall of the directional rail b1. The elastic abutting assembly b5 is also installed on the sliding frame 4 of the child vehicle 3 and is used for pushing the rolling part of the rolling assembly b4 to the inner rail wall of the directional rail b1. That is, through the arrangement of the elastic abutting assembly b5, the rolling assembly b4 can be pushed to the inner rail wall of the directional rail b1, so that the rolling assembly b4 is stably contacted with the inner rail wall of the directional rail b1.

[0074] In combination Figure 7 ,8 The rolling assembly b4 comprises a rotating plate b41, a rotating rod b42 and an abutting wheel b43. One end of the rotating plate b41 is rotationally connected with the main shaft b3, and the rotating plate b41 is perpendicular to the main shaft b3, that is, the main shaft b3 and the rotating plate b41 form an L shape. The rotating rod b42 is vertically arranged on the rotating plate b41, and the rotating rod b42 is located away from the main shaft b3. The abutting wheel b43 is coaxially rotationally arranged on the rotating rod b42, and the abutting surface of the abutting wheel b43 faces the inner rail wall of the directional rail b1. The elastic abutting assembly b5 is mainly used for abutting the rotating plate b41, that is, the elastic abutting assembly b5 applies a pushing force to the rotating plate b41, so that the rotating plate b41 is pushed to move towards the inner rail wall side of the directional rail b1 with the main shaft b3 as the rotation center, and finally the wheel surface of the abutting wheel b43 abuts on the inner rail wall of the directional rail b1.

[0075] With reference to Figure 7 , 8 The elastic abutting assembly b5 comprises a support b51, a connecting rod b52 and a spring b53. The support b51 is installed on the sliding frame 4 of the sub-car 3 and located above the cavity. The connecting rod b52 is transversely installed between the rotating plate b41 and the support b51. One end of the connecting rod b52 close to the rotating plate b41 is slidingly connected with the rotating plate b41, and the other end of the connecting rod b52 close to the support b51 is fixedly connected with the support b51. Specifically, a waist-shaped hole b411 is formed in the rotating plate b41, and the connecting rod b52 is inserted into the waist-shaped hole b411. A limiting nut b7 is threadedly sleeved on the rod segment of the connecting rod b52 located in the waist-shaped hole b411, and the limiting nut b7 is used to prevent the connecting rod b52 from being separated from the waist-shaped hole b411. The spring b53 is sleeved on the connecting rod b52, one end of the spring b53 abuts against the rotating plate b41, and the spring b53 always has a tendency to push the rotating plate b41 towards the inner wall of the directional rail b1.

[0076] That is, the spring b53 itself can apply a pushing force to the rotating plate b41, so that the rotating plate b41 moves towards the inner rail wall side of the directional rail b1 after being subjected to the pushing force, and finally the abutting wheel b43 abuts on the inner rail wall of the directional rail b1. Since the waist-shaped hole b411 is formed in the rotating plate b41, there is a gap between the connecting rod b52 and the waist-shaped hole b411 after the connecting rod b52 is inserted into the waist-shaped hole b411. The gap allows the rotating plate b41 to still rotate to a certain extent after being subjected to the elastic force of the spring b53. That is, the spring b53 can directly push the rotating plate b41 towards the inner rail wall of the directional rail b1 under the action of its own elastic force, and finally the abutting wheel b43 can stably adhere to the inner rail wall of the directional rail b1 under the action of the elastic force of the spring b53.

[0077] It is worth noting that in the present embodiment, when the abutting wheel b43 is abutted on the inner wall of the directional rail b1 by the pushing force of the spring b53, the limiting nut b7 located in the waist-shaped hole b411 does not fit on the inner wall of the waist-shaped hole b411, but there is still a gap, so that the pushing force of the spring b53 is always transmitted to the rotating plate b41, and the abutting wheel b43 is always abutted on the inner rail wall of the directional rail b1, thereby improving the stability of the abutting wheel b43 abutting on the inner rail wall of the directional rail b1.

[0078] In combination Figure 7 , 8 , the rolling guide mechanism b6 includes a fixed shaft b61 and a guide wheel b62; the fixed shaft b61 is vertically installed on the sliding frame 4 of the sub-car 3, and the fixed shaft b61 vertically extends downward into the cavity between the two groups of directional rails b1; that is, after the rolling abutting mechanism b2 is installed, the guide wheel b62 on the fixed shaft b61 is directly installed to be in abutting state with the inner rail wall of the other group of directional rails b1, at this time, the abutting wheel b43 is abutted and fitted with the inner rail wall of the first group of directional rails b1, and the guide wheel b62 is abutted with the inner rail wall of the other group of directional rails b1, thereby realizing stable limiting and guiding effect of the sliding frame 4 of the sub-car 3.

[0079] In combination Figure 7 , 8 , the directional rail b1 is provided with an abutting plate b8 close to the mother car 1, the abutting plate b8 is perpendicular to the directional rail b1 and connected with the top plate 2 of the mother car 1; the abutting plate b8 can be bolted or directly welded on the top plate 2 of the mother car 1, which is convenient for positioning the directional rail b1 vertically installed on the top plate 2 of the mother car 1. The end of the directional rail b1 close to the sub-car 3 is provided with a bearing plate b9, the bearing plate b9, the directional rail b1 and the abutting plate b8 form a U shape, which can improve the structural stability of the directional rail b1 after installation.
