[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of a hydraulic hoisting frame for construction engineering, including a base 1. A fixed column 4 is fixedly connected to the top of the outer wall of the base 1, and four sets of universal wheels 2 are rotatably connected to the bottom of the outer wall of the base 1. The four sets of universal wheels 2 can move and transport objects lifted by the hoisting mechanism 5. The hoisting mechanism 5 is provided at the top of the outer wall of the fixed column 4. The hoisting mechanism 5 is the prior art. A hydraulic cylinder is provided at its top. By moving the hydraulic cylinder up and down, the hoisting frame at the other end can lift the building materials. An unfolding component 3 is provided on the surface of the base 1.

[0033] Reference Figure 2 and Figure 3 The unfolding component 3 includes a rotating disk 31. The surface of the rotating disk 31 has four sets of inclined grooves. Slider 32 are slidably connected to the inner walls of the inclined grooves of the rotating disk 31. As the rotating disk 31 rotates around the outer wall of the fixed column 4, it can push the four sets of sliders 32 closer together or further apart within their inclined grooves. Simultaneously, the sliders 32 also slide on the inner wall of the guide groove of the base 1. This rotation of the rotating disk 31 allows the four sets of sliders 32 to move synchronously outwards or closer together on the inner wall of the guide groove at the top of the base 1. The rotating disk 31 passes through and is rotatably connected to the outer wall of the fixed column 4. The surface of the base 1 has four sets of guide grooves, and the bottom of the sliders 32... The outer wall of the end is slidably connected to the inner wall of the guide groove of the base 1. The surface of the slider 32 is hinged with a hinge rod 33. The end of the hinge rod 33 away from the slider 32 is hinged with a connecting rod 34. The four sets of sliders 32 move on the inner wall of the guide groove of the base 1, thereby pushing the connecting rod 34 to rotate around the rotation center point of the base 1 through the hinge rod 33, so that the four sets of fixed sleeves 61 can be quickly unfolded and stored in the position of the inner wall of the base 1. The connecting rod 34 is rotatably connected to the inner side wall of the base 1. One end of the limiting spring 36 is fixedly connected to the surface of the insertion rod 37, and the other end of the limiting spring 36 is fixedly connected to the inner wall of the top of the connecting seat 35.

[0034] Reference Figure 2 and Figure 3 The function of the limiting spring 36 is to automatically reset the position of the insert rod 37 after it is pulled outward. The end of the connecting rod 34 is provided with a support component 6. The top of the outer wall of the rotating disk 31 is fixedly connected to the connecting seat 35. When the insert rod 37 inside the connecting seat 35 is disengaged from the through hole of the fixed post 4, the rotating disk 31 can be rotated synchronously by rotating the connecting seat 35. The inner wall of the top of the connecting seat 35 is elastically connected to the insert rod 37 through the limiting spring 36. The insert rod 37 passes through and slides on the inner wall of the top of the connecting seat 35. The outer wall of the fixed post 4 is provided with a through hole. The bottom end of the outer wall of the insert rod 37 is inserted into the inner wall of the through hole. The insertion between the two allows the rotating disk 31 to drive the slider 32 and the corresponding hinge rod 33 to push the connecting rod 34 to move outward to multiple positions and fix them, thereby facilitating the support component 6 for use.

[0035] Reference Figure 2 and Figure 4 The support component 6 includes a fixed sleeve 61, which is fixedly connected to the end of the connecting rod 34. When the connecting rod 34 is pushed by the hinge rod 33, it will drive the fixed sleeve 61 to unfold synchronously, thereby facilitating the operation of the sliding sleeve 64 and the threaded rod 65 by the operator. The outer wall of the fixed sleeve 61 is in contact with the outer side wall of the base 1. The inner wall of the top of the fixed sleeve 61 is elastically connected to the insert 63 through the return spring 62. The insert 63 has a handle on the left and a protrusion on the right, and the protrusion corresponds to the through hole on the surface of the sliding sleeve 64. One end of the return spring 62 is fixedly connected to the outer wall of the insert 63, and the other end of the return spring 62 is fixedly connected to the inner wall of the top of the fixed sleeve 61. The function of the return spring 62 is to automatically reset the position of the insert 63 after it is pulled outward.

[0036] Reference Figure 4 A sliding sleeve 64 is slidably connected through the inner wall of the fixed sleeve 61. The inner wall of the sliding sleeve 64 has an internal thread, and a threaded rod 65 is threadedly connected through the inner wall of the sliding sleeve 64. A handle is provided at the top of the threaded rod 65. The threaded rod 65 can be rotated by the handle to lower the threaded rod, thereby allowing the support block 66 to contact the ground. This increases the stability of the entire device when lifting the building. The support block 66 is fixedly connected to the bottom of the outer wall of the threaded rod 65. An insert 63 is slidably connected through the inner wall of the top of the fixed sleeve 61. The outer wall of the sliding sleeve 64 has a through hole, and the end of the insert 63 is inserted into the inner wall of the through hole of the sliding sleeve 64. The insertion of the two can fix the sliding sleeve 64 at multiple positions when it is rapidly lowered through the inner wall of the fixed sleeve 61, thereby quickly allowing the support block 66 to contact the ground. At the same time, the support block 66 can be finely adjusted by driving the threaded rod 65.

[0037] Working principle: When the support assembly 6 needs to be deployed, pull the insert rod 37 outward to disengage it from the through hole on the outer wall of the fixed column 4. At this time, the limit spring 36 is stretched. Then, rotate the connecting seat 35, which drives the rotating disk 31 to rotate synchronously. As the rotating disk 31 rotates around the outer wall of the fixed column 4, it pushes the four sets of sliders 32 away from each other in their inclined grooves. At the same time, the sliders 32 slide on the inner wall of the guide groove of the base 1. The four sets of sliders 32 move outward on the inner wall of the guide groove of the base 1, pushing the connecting rod 34 around the base 1 via the hinge rod 33. The rotation center point is rotated, so that the support component 6, which is fixedly connected to the end of the connecting rod 34, can be quickly unfolded from the position of the inner wall of the base 1. When the support component 6 is unfolded to the appropriate position, the insertion rod 37 is released, and the limit spring 36 automatically resets the position of the insertion rod 37 after it is pulled outward, so that the bottom end of the outer wall of the insertion rod 37 is inserted into the through hole at the current position of the outer wall of the fixed column 4. The rotating disk 31 drives the slider 32 and the corresponding hinge rod 33 to push the connecting rod 34 to move outward and fix the position, so that the support component 6 can be used for support.

[0038] After the support assembly 6 is deployed, the insert 63 is pulled outward to disengage it from the through hole on the outer wall of the sliding sleeve 64. At this time, the return spring 62 is stretched, and then the sliding sleeve 64 descends rapidly on the inner wall of the fixed sleeve 61, causing the support block 66 to quickly contact the ground and release the insert 63. The return spring 62 automatically resets the position of the insert 63 after it has been pulled outward, so that the end of the insert 63 is inserted into the through hole at the current position of the sliding sleeve 64, fixing the sliding sleeve 64 in the position where it descends rapidly on the inner wall of the fixed sleeve 61. Then, by rotating the handle at the top of the threaded rod 65, the threaded rod 65 descends threadedly, driving the support block 66 to make fine adjustments without the need for the operator to repeatedly rotate the threaded rod 65 to descend.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
