[0003] In the above scheme, the chassis is fixedly connected to the vehicle body, which can be a non-detachable fixed connection or a detachable fixed connection; if it is a non-detachable fixed connection, it will affect the normal use of the vehicle body (such as the appearance of the vehicle body, the upward shift of the center of gravity leading to reduced stability when measuring high-speed driving, etc.). Therefore, it is preferred that the chassis and the vehicle body are detachably fixedly connected, so that when the foldable roof house is needed, the chassis and the components assembled on the chassis are installed on the vehicle body, and when not needed, the chassis and the components assembled on the chassis can be removed from the vehicle body, so that the foldable roof house does not affect the normal use of the vehicle body.

[0004] As for the detachable underframe from the vehicle body, since the underframe is heavy and needs to be installed on the roof, it is difficult to remove and install the underframe from the roof and requires the cooperation of multiple people to achieve it, and there is a high risk factor when removing and installing the underframe.

[0005] To this end, on the basis of "CN220639661 U-A car gantry crane linked folding roof house", further research and development was carried out to solve the above technical problems. Utility Model Content

[0009] Furthermore, the first locking mechanism includes a bolt hole group and a bolt member arranged on the center tube and the horizontal side rod. There are multiple bolt holes arranged along the length direction in the bolt hole group. The positions of the bolt holes on the center tube and the bolt holes on the horizontal side rod match. The screw rod of the bolt member passes through the bolt holes on the center tube and the horizontal side rod at the same time and is threadedly connected with the nut of the bolt member.

[0010] Furthermore, the first steel rope guide is fixed to the middle part of the center pipe, and there are two groups of bolt holes on the center pipe, and the two groups of bolt holes are mirror-symmetrical about the center plane of the center pipe.

DETAILED DESCRIPTION

[0025] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0026] Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0027] Example 1

[0028] like Figure 1-Figure 4As shown, a lifting frame includes a horizontally installed center tube 1 and an "L"-shaped support rod 2, the axis direction of the center tube 1 is parallel to the horizontal direction; the support rod 2 is assembled at both ends of the center tube 1 and assembled with the center tube 1 to form a "door" type structure, and the horizontal side rod 21 of the support rod 2 is slidably connected with the center tube 1, that is, the outer cross-sectional size of the horizontal side rod 21 matches the cross-sectional size of the tube hole of the center tube 1, and the horizontal side rod 21 is slidably connected with the center tube 1, that is, the depth of the horizontal side rod 21 inserted into the center tube 1 is adjusted, and the vertical side rod 22 of the support rod 2 is parallel to the vertical direction, that is, the spacing between the vertical side rods 22 located at both ends of the center tube 1 is adjusted, so that the "door width" can be adjusted. large, thereby ensuring that the "door" has a "door width" sufficient to accommodate the vehicle body, that is, the measuring body can enter the space between the vertical side bars 22; a first locking mechanism 3 is provided between the horizontal side bars 21 and the center tube 1, so as to achieve the purpose of locking the horizontal side bars 21 and the center tube 1, ensuring the stability of the width of the "door" and avoiding the stability of the lifting frame when lifting the base frame; a first steel rope guide 5 is provided on the center tube 1, when the base frame is lifted, the steel wire rope 10 of the winch unit passes through the first steel rope guide 5, and the first steel rope guide 5 is equivalent to a fixed pulley to change the movement direction of the steel rope, and effectively prevent the steel wire rope 10 from getting stuck when the base frame is lifted.

[0029] In this embodiment, the first steel rope guide 5 may be a fixed pulley structure; or Figure 4 As shown, the first steel rope guide 5 can be composed of multiple groups of rotating roller groups, each rotating roller group has two rotating rollers 11 that can rotate about its own axis, and there is a gap between the rotating rollers 11 for the steel wire rope 10 to pass through, so as to guide the steel wire rope 10 and restrain the steel wire rope 10 to prevent the steel wire rope 10 from escaping from the steel wire rope 10 guide in a relaxed state.

[0030] In this embodiment, the lifting frame is placed on the ground, the ground supports the support rod 2, the support rod 2 supports the mid-position pipe 1, the wire rope 10 of the winch group passes through the first wire guide and is fixed to the base frame, the winch body is installed on the base frame, and is one of the structures on the frame. For details, see the scheme disclosed in the Chinese utility model patent with publication number "CN220639661 U" and name "A Automobile Gantry Crane Linked Folding Lifting Roof Board House"; the winch body works to reel in or release the wire rope 10, thereby lifting or lowering the base frame; the lifting force generated by the winch body is used instead of manual labor to carry the base frame, thereby reducing labor intensity and improving safety.

[0031] Specifically, if the chassis needs to be installed on the vehicle body, the lifting frame is first installed and arranged, and the chassis is placed in the "door". The wire rope 10 is connected as described above, the winch body is operated, the wire rope 10 is reeled in, and the chassis is lifted; then the vehicle body can be moved into the "door" and located under the chassis. After aligning with the installation position, the winch body is operated, the wire rope 10 is released, and the chassis is lowered until it is placed on the top of the measuring body, thereby realizing the connection between the chassis and the vehicle body.

[0032] If it is necessary to remove the underframe from the vehicle body, first install and arrange the lifting frame, and make the vehicle body with the underframe inside the "door", connect the wire rope 10 as mentioned above, and remove the connection position between the underframe and the measuring body, and then start the winch body to wind up the wire rope 10, and the underframe will be separated from the vehicle body after it is lifted; then the vehicle body can be moved outside the "door"; after moving out of the vehicle body, the winch body will start to release the wire rope 10, and the underframe will be lowered to the ground, completing the removal of the underframe.

[0033] In summary, this method greatly reduces the number of personnel required for installing and disassembling the chassis, and there is no need to manually lift the chassis to the roof or go up and down from the roof, thereby improving the safety factor of personnel during installation.

[0034] Example 2

[0035] On the basis of Example 1, a specific implementation method is further proposed in terms of the stability of the "door" type structure.

[0036] The "door" type structure is restricted in the lateral direction by the center tube 1 and the support rods 2 located at both ends of the center tube 1, that is, it has a span in the lateral direction, so the "door" type structure will not tip over in the lateral direction; however, with regard to the scheme disclosed in Example 1, the "door" type structure is not restricted in the longitudinal direction, which can easily cause the "door" type structure to tip over in the longitudinal direction; in order to solve this problem, the following implementation methods are proposed.

[0037] The first implementation mode for installation or removal is to drill a hole on the ground that matches the position of the vertical side rod 22, insert the vertical side rod 22 into the hole, and use the hole wall to constrain the vertical side rod 22 so that the vertical side rod 22 will not fall in the longitudinal direction.

[0038] The second implementation method, such as Figure 2As shown, the number of the center tubes 1 is at least two, and all the center tubes 1 are arranged longitudinally, that is, multiple center tubes 1 are arranged perpendicular to the axis of the center tube 1, and adjacent center tubes 1 are connected by connectors 9, so that all center tubes 1 are connected as a whole, and both ends of each center tube 1 are slidably connected with "L"-shaped support rods 2; through this implementation, the "door" type structure has a span in the longitudinal direction, which effectively prevents the "door" type structure from tipping in the longitudinal direction and improves the stability of the "door" type structure. Of course, it is also possible to add connectors 9 between the support rods 2 connected to different center tubes 1 to further improve the stability of the longitudinal span, thereby further preventing the "door" type structure from tipping in the longitudinal direction.

[0039] The third implementation method, such as Figure 3 As shown, the number of the median tube 1 is one, and the vertical side rod 22 is detachably connected with a triangular frame 8, and the plane where the triangular frame 8 is assembled is parallel to the plane formed by the vertical and longitudinal directions; the triangular frame 8 spans the connecting rod, that is, the vertical side rod 22 is the height of the triangular frame 8; adding the triangular frame 8 also allows the "door" type structure to have a span in the longitudinal direction, effectively preventing the "door" type structure from tipping over in the longitudinal direction, and improving the stability of the "door" type structure.

[0040] In the third embodiment, the triangular frame 8 is preferably an isosceles triangle, so that the spans of the triangular frame 8 on both sides of the vertical rod 22 in the longitudinal direction are consistent, further improving the stability of the longitudinal span.

[0041] In the third embodiment, a reinforcing member is provided between the two oblique sides (sides not perpendicular to the vertical side rods 22 ) of the triangular frame 8 to strengthen the strength of the triangular frame 8 , thereby improving the diagonal bracing capacity of the two oblique sides of the triangular frame 8 .

[0042] In this embodiment, the third implementation is preferred as a solution to ensure the stability of the "door" type structure, so that the "door" type structure in the lifting frame can be used as a U-shaped frame for a folding roof house linked to a car gantry crane.

[0043] Example 3

[0044] Based on any one of the implementations in Examples 1-2, a specific implementation method that can be implemented is further proposed.

[0045] A feasible implementation manner, the first locking mechanism 3 includes a bolt hole group and a bolt member arranged on the center tube 1 and the horizontal side rod 21, there are multiple bolt holes arranged along the length direction in the bolt hole group, the bolt holes on the center tube 1 and the bolt holes on the horizontal side rod 21 match each other in position, the screw rod of the bolt member simultaneously passes through the bolt holes on the center tube 1 and the horizontal side rod 21 and is threadedly connected with the nut of the bolt member; when adjusting the spacing of the vertical side rods 22 in the "door" type structure, that is, when adjusting the horizontal span of the "door" type structure, the bolt holes on the horizontal side rod 21 are aligned with the bolt holes on the center tube 1, and then the screw rod simultaneously passes through the bolt holes on the center tube 1 and the horizontal side rod 21 and is locked with the nut, so that the bolt member locks the center tube 1 and the horizontal side rod 21.

[0046] A feasible implementation method is that the first steel rope guide 5 is fixed to the middle part of the center tube 1, and there are two groups of bolt holes on the center tube 1, and the two groups of bolt holes are mirror-symmetrical about the center plane of the center tube 1, so as to ensure that the first steel rope guide 5 can always be kept in the middle position, meeting the requirements of the scheme disclosed in the Chinese utility model patent with publication number "CN220639661 U" and name "A kind of automobile gantry crane linked folding roof board house".

[0047] A feasible implementation method is that a second steel rope guide 6 is provided at the corner of the support rod 2, and the structure and function of the second steel rope guide 6 are the same as those of the first steel rope guide 5; after the wire rope 10 starts from the winch body, it passes through the first steel rope guide 5 and the second steel rope guide 6 and is then fixedly connected to the base frame; compared with only the first steel rope guide 5, there are four steel ropes between the top of the "door" type structure (the center tube 1 and the horizontal side rod 21) and the base frame, which improves the lifting bearing capacity while allowing the steel ropes to have a lateral span, avoiding lateral shaking of the steel rope when tightening, thereby ensuring the stability and safety of the lifting.

[0048] Example 4

[0049] On the basis of any one of the implementations in Examples 1-3, in order to reduce the area occupied by the lifting frame when not in use, a specific implementation method that can be implemented is further proposed.

[0050] A feasible implementation manner is that the support rod 2 is detachably connected to the center tube 1, that is, the support rod 2 can be pulled out from the center tube 1; when the lifting frame is not in use, that is, when the lifting frame is placed in a warehouse, garage or other place, the horizontal side rod 21 can be pulled out of the center tube 1 and then placed in an overlapping manner, thereby effectively reducing the area occupied by the lifting frame.

[0051] A feasible implementation manner further includes a vertically mounted vertical pipe 7 that is slidably connected to the vertical side bar 22, and a second locking mechanism 4 is provided between the vertical pipe 7 and the vertical side bar 22; the structure of the second locking mechanism 4 is the same as the first locking mechanism 3, including a bolt hole group and a bolt member provided on the vertical side bar 22 and the vertical pipe 7, and the vertical side bar 22 and the vertical pipe 7 can be locked by the bolt member. The vertical pipe 7 can effectively reduce the length of the vertical side bar 22, thereby effectively reducing the area occupied by the lifting frame; on the other hand, the vertical height of the "door" type structure can be adjusted.

[0052] It should be noted that by setting the median tube 1, the support rod 2 and the vertical tube 7, the lateral span and the vertical height of the "door" type structure can be adjusted, which provides a basis for the subsequent adjustment of the space size of the folding and lifting roof board house linked by the automobile gantry crane. That is, if the "door" type structure of the lifting frame is used as the U-shaped frame of the folding and lifting roof board house linked by the automobile gantry crane, the lateral span and vertical height of the U-shaped frame can be achieved, thereby providing a prerequisite for the adjustment of the space size of the board house.

[0053] A feasible implementation method is that the vertical side rod 22 is detachably connected to the vertical tube 7. The principle and effect are the same as the detachable connection between the horizontal side rod 21 and the center tube 1, and will not be explained in detail again.

[0054] Example 5

[0055] A folding roof-lifting house linked with a car gantry crane adopts the lifting frame described in any one of the implementation modes of Examples 1-4 as a U-shaped frame, that is, the "door"-shaped structure in the lifting frame serves as the U-shaped frame.

[0056] In this embodiment, further, a hinge hole 71 is provided at the bottom end of the vertical side rod 22 or the vertical pipe 7 to realize the hinge connection between the "door" type structure as a U-shaped frame and the base frame.

[0057] In this embodiment, after the base frame is installed, since the lateral span of the "door" type structure is larger than the lateral dimension of the base frame, when connecting the "door" type structure to the base frame, it is necessary to adjust the lateral span of the door type structure to match the lateral dimension of the base frame.

[0058] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
