DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1 and Figure 3 The installation structure of the vehicle-mounted crane and the flatbed truck in this embodiment includes a crane supporting beam 1, a mounting mechanism 2 is provided on the front of the crane supporting beam 1, a fixing mechanism 3 is provided on the outside of the mounting mechanism 2, the mounting mechanism 2 includes two frames 201, and connecting brackets 202 are fixedly installed on the opposite sides of the two frames 201 and the front of the crane supporting beam 1, and a seat ring beam assembly 203 is slidably installed between the opposite sides of the two frames 201, and the seat ring beam assembly 203 can be separated from the frame 201.

[0023] Among them, the inner bottom wall of the seat ring crossbeam assembly 203 is rotatably installed with a threaded rod 204 with one end passing through and extending to the outside thereof, and a movable hole is opened at the top of the seat ring crossbeam assembly 203. The inner surface of the movable hole is rotatably connected to the outer surface of the threaded rod 204, and a slider 205 is threadedly installed on the outer surface of the threaded rod 204. The front and rear side walls of the inner cavity of the seat ring crossbeam assembly 203 are both provided with sliding grooves, and the inner surfaces of the two sliding grooves are respectively slidably connected to the front and rear sides of the slider 205, and the threaded rod 204 enables the slider 205 to move through the sliding grooves.

[0024] Among them, two connecting rods 208 are rotatably installed on the left and right sides of the slider 205, and the other ends of the four connecting rods 208 are rotatably installed with insertion rods 206. The front and rear side walls of the inner cavity of the seat ring beam assembly 203 are provided with fixing grooves, and the inner surfaces of the four fixing grooves are respectively embedded with the outer surfaces of the four insertion rods 206. The slider 205 drives the four insertion rods 206 from the inside of the frame 201 to the inside of the seat ring beam assembly 203 through the four connecting rods 208.

[0025] Among them, the top and bottom of the insertion rod 206 are fixedly installed with limiting blocks 207, and the inner top wall and inner bottom wall of the fixed groove are provided with limiting grooves. The outer surfaces of the two limiting blocks 207 are respectively slidably connected to the inner surfaces of the two limiting grooves, and the limiting blocks 207 limit the insertion rod 206 from sliding into the seat ring crossbeam assembly 203.

[0026] Specifically, the threaded rod 204 is rotated by a tool to move the slider 205 upward, and the slider 205 drives the four insertion rods 206 from the inside of the frame 201 to the inside of the seat ring crossbeam assembly 203 through the four connecting rods 208. The insertion rods 206 are restricted by the limit blocks 207 to slide into the inside of the seat ring crossbeam assembly 203, so that the seat ring crossbeam assembly 203 is separated from the frame 201, which facilitates the disassembly of the vehicle-mounted crane and the cart, reducing the complexity and time cost of the work.

[0027] Example 2: Please refer to Figure 1 and Figure 2 On the basis of the first embodiment, the fixing mechanism 3 includes a threaded tube 301, the bottom of the threaded tube 301 is fixedly connected to the top of the seat ring beam assembly 203, an interlocking sleeve 302 is interlocked between the inner surface of the threaded tube 301 and the outer surface of the threaded rod 204, a fixing cover 303 is threadedly installed on the outer surface of the threaded tube 301, the interlocking sleeve 302 prevents the threaded rod 204 from loosening, and the fixing cover 303 fixes the interlocking sleeve 302.

[0028] Among them, the inner surface of the threaded tube 301 and the outer surface of the threaded rod 204 are both hexagonal, the inner surface and outer surface of the fitting sleeve 302 are both hexagonal, the front of the seat ring crossbeam assembly 203 is fixedly installed with a crane seat ring 304, and the front of the crane seat ring 304 is fixedly installed with a truck crane 305, and the lifting operation is achieved by the truck crane 305.

[0029] Specifically, when the vehicle-mounted crane 305 is disassembled, the fixing cover 303 is unscrewed, and then the fitting sleeve 302 is taken out, which prevents the threaded rod 204 from loosening, and prevents the mounting structure of the vehicle-mounted crane and the flatbed truck from loosening, thereby meeting the user's usage needs.

[0030] The working principle of the above embodiment is:

[0031] (1) When disassembling the vehicle-mounted crane 305, unscrew the fixing cover 303, then take out the fitting sleeve 302, and use a tool to rotate the threaded rod 204 to move the slider 205 upward. The slider 205 drives the four insertion rods 206 from the inside of the frame 201 to the inside of the seat ring crossbeam assembly 203 through the four connecting rods 208. The insertion rods 206 are restricted by the limit blocks 207 from sliding into the inside of the seat ring crossbeam assembly 203, so that the seat ring crossbeam assembly 203 is separated from the frame 201.

[0032] (2) Similarly, the vehicle frame 201 and the seat crossbeam assembly 203 can be fixed by four insertion rods 206. In this case, the insertion rods 206 can only move through the fixing grooves. When moving toward the connecting rod 208, the connecting rod 208 will limit the insertion rod 206 so that the insertion rod 206 cannot fall out.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
