Specific embodiments

[0022] In order to further explain the technical solution of the present utility model, the following will be elaborated in detail through specific embodiments.

[0023] Please refer to Figure 1 , the present utility model provides a device for transporting earth and stone in a building foundation pit, including a vehicle body 1, wheels 2, a fixed bracket 3, and a lifting and adjusting device 4. The middle part of the bottom surface of the vehicle body 1 is installed and connected to the wheels 2 through an axle. A fixed bracket 3 is welded at the tail of the vehicle body 1, and a lifting and adjusting device 4 is arranged on the surface of the vehicle body 1.

[0024] Please refer to Figures 2-4 , the present utility model provides a device for transporting earth and stone in a building foundation pit. The lifting and adjusting device 4 includes a lifting ring 41, a rod support sleeve 42, a thread groove 421, a rod 43, a first threaded section 431, and a second threaded section 432. Lifting rings 41 are welded at the four corner positions along the top edge of the vehicle body 1. Rod support sleeves 42 are bolt - installed at the top edge positions on the left and right sides of the vehicle body 1. A rod 43 is movably sleeved inside the rod support sleeve 42. The rod 43 can slide outwards along the rear opening of the rod support sleeve 42. A thread groove 421 is arranged inside the rear opening of the rod support sleeve 42. A first threaded section 431 is arranged on the front surface of the rod 43, and a second threaded section 432 is arranged on the rear surface of the rod 43. Both the first threaded section 431 and the second threaded section 432 can be thread - connected to the inside of the thread groove 421, thereby realizing the position adjustment and fixation of the rod 43.

[0025] Furthermore, a limit retaining ring 433 is fixedly sleeved on the front end of the rod 43. The limit retaining ring 433 is located in front of the first threaded section 431 and they are connected. The outer diameter of the limit retaining ring 433 is larger than the inner diameter of the thread groove 421, so that the limit retaining ring 433 cannot pass through the thread groove 421, preventing the first threaded section 431 from being screwed out of the thread groove 421 and resulting in unstable connection between the rod 43 and the rod support sleeve 42.

[0026] Furthermore, the lengths of the first threaded section 431 and the second threaded section 432 are the same, and the length is not less than 5 cm, so that the first threaded section 431 and the second threaded section 432 can have a sufficient connection length with the threaded groove 421 and are not easily loosened and disengaged by themselves.

[0027] Please refer to Figures 5-6 , the present utility model provides a device for transporting earth and stone in a building foundation pit. The lifting and adjusting device 4 further includes a support sleeve 44, a movable support 45, a first positioning hole 46, a second positioning hole 47 and a positioning bolt 48. Support sleeves 44 are welded and arranged at the front edge positions on the left and right sides of the vehicle body 1. The support sleeves 44 are parallel to the fixed support 3. A movable support 45 is slidably installed inside the support sleeve 44. The movable support 45 can cooperate with the fixed support 3 to provide fixed support for the vehicle body 1 together, enhancing the lifting stability of the vehicle body 1. The movable support 45 can slide outwards along the bottom opening of the support sleeve 44. A first positioning hole 46 is penetrated through the lower end of the movable support 45, and a second positioning hole 47 is penetrated through the upper end of the movable support 45. A positioning bolt 48 is threadedly connected to the screw hole at the lower end outside the support sleeve 44. The positioning bolt 48 can be screwed into the inside of the support sleeve 44 and inserted into the first positioning hole 46 or the second positioning hole 47.

[0028] Furthermore, the bottom end of the movable support 45 is designed to be round-headed, which can better use the bottom end of the movable support 45 as a fulcrum to lift the vehicle body 1 forward for unloading.

[0029] Furthermore, auxiliary grips 49 are symmetrically installed at the left and right ends of the tail of the vehicle body 1. When the support rod 43 is in the retracted state, the auxiliary grips 49 can be used to control the tilting action of the vehicle body 1.

[0030] The working principle is as follows:

[0031] First, before use, first adjust and expand the support rod 43 from the support rod sleeve 42. The specific operation method is: rotate the support rod 43 to screw out the second threaded section 432 from the threaded groove 421, and then the support rod 43 can be slid out of the support rod sleeve 42 until the first threaded section 431 contacts the threaded groove 421. At this time, rotate the support rod 43 again to screw the first threaded section 431 into the threaded groove 421 to fix the position of the support rod 43 and the support rod sleeve 42, so that the support rod 43 is kept in the expanded state. Among them, by setting a limit snap ring 433 at the front end of the support rod 43, the limit snap ring 433 cannot pass through the threaded groove 421, which can prevent the first threaded section 431 from being screwed out of the threaded groove 421 and causing the connection between the support rod 43 and the support rod sleeve 42 to be unstable.

[0032] Second, when in use, the excavated soil and rocks are loaded into the vehicle body 1, and then the handle 43 is held to lift the rear part of the vehicle body 1. After the fixed bracket 3 is lifted off the ground, the vehicle body 1 can be moved by the wheels 2, which is consistent with the use of the trolley in the prior art.

[0033] Third, during the foundation pit construction process, due to the height difference of the terrain, it is sometimes necessary to lift and transfer the vehicle body 1. At this time, the structure of the vehicle body 1 can be adjusted through the lifting adjustment device 4. The specific operation method is: rotate the support rod 43 to make the No. 1 thread segment 431 screw out from the thread groove 421, and then push the support rod 43 into the inside of the support rod sleeve 42 until the No. 2 thread segment 432 contacts the thread groove 421. At this time, rotate the support rod 43 again to make the No. 2 thread segment 432 screw into the thread groove 421, so that the support rod 43 can be kept in the retracted state. After the support rod 43 is retracted, the center of gravity of the vehicle body 1 is more balanced and stable, and it is easy to lift.

[0034] Fourth, after completing the folding action of the handrail 43, loosen the positioning bolt 48 to make it disengage from the inner side of the No. 1 positioning hole 46, then slide the movable bracket 45 downward along the bottom opening of the bracket sleeve 44 to unfold it, and finally tighten the positioning bolt 48 to screw it into the No. 2 positioning hole 47 to fix the position of the movable bracket 45 and the bracket sleeve 44, thereby completing the unfolding operation of the movable bracket 45. After unfolding, the movable bracket 45 can cooperate with the fixed bracket 3 to provide fixed support for the vehicle body 1, thereby preventing the vehicle body 1 from moving by itself through the wheels 2 when it is hoisted, thereby enhancing the hoisting stability of the vehicle body 1.

[0035] Fifth, after the deployment of the lifting adjustment device 4 is completed, the lifting rope of the external crane is connected to the lifting ring 41, and then the vehicle body 1 can be lifted normally for transportation, which enhances the lifting function of the vehicle body 1 and makes it better suitable for lifting work.

[0036] The above are only preferred examples of the present invention and are not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
