Description

Technical Field

[0001] The invention relates to the technical field of lifting devices, and in particular to a lifting construction system for assembled buildings. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods. During the construction process of prefabricated buildings, a jacking device is required to place a platform for transportation. However, existing jacking devices are usually placed directly on the ground for use, which may slip or shake during use, resulting in poor construction safety.

[0003] To solve the above problems, Chinese patent with publication number CN207713341U discloses a jacking device for construction, including a support plate, a jack is fixed on the top of the support plate, a top plate is fixed on the top of the piston rod of the jack, four support feet evenly distributed in the circumferential direction are fixed on the lower end surface of the support plate, a screw is passed through the horizontal edge of the support foot, a turntable is fixed on the upper end of the screw, a rotating handle is provided at the edge of the upper end surface of the turntable, a pad is provided under each support foot, a socket is provided on the upper end surface of the pad for inserting the lower end of the screw, an annular boss is provided on the outer side wall of the screw for abutting against the upper end surface of the pad after the screw is inserted into the socket, and an anti-skid rubber pad is fixed on the lower end surface of the pad; the patent can increase the friction with the ground through the anti-skid rubber pad, thereby enhancing the anti-skid effect and improving the safety of construction.

[0004] During the actual use of the above-mentioned patent, although the contact between the anti-slip rubber pad and the ground can increase the friction so as to enhance the anti-slip effect, the pad and the anti-slip rubber pad are still in a movable state. Therefore, sliding or shaking will still occur under a large external force, resulting in poor construction safety. Summary of the invention

[0005] The present invention is intended to provide a jacking construction system for assembled buildings to solve the problem of poor construction safety of existing jacking devices.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a system for lifting construction of prefabricated buildings, including a base and a top plate, a telescopic rod is provided on the base, and the telescopic rod is fixedly connected to the top plate; adjusting screws are provided on both sides of the telescopic rod on the base, and a movable block is threadedly connected to the adjusting screw, and the movable block is fixedly connected to the top plate; side plates are provided on both sides of the base, and at least one threaded hole is provided on the side plate, and a positioning screw is threadedly connected in the threaded hole; and a driving mechanism for simultaneously driving the two adjusting screws to rotate in the same direction.

[0007] The principles and advantages of this solution are: this solution places the base at a specified position, and rotates multiple positioning screws one by one. The positioning screws move downward along the path of the threaded holes, so that the positioning screws drill into the ground, thereby fixing the base on the ground; the driving mechanism drives the two adjusting screws to rotate simultaneously and in the same direction, so that the movable block moves vertically, and the movable block drives the top plate to move vertically, and the telescopic rod is extended and retracted accordingly, so that the top plate moves to the specified position; compared with the prior art, this solution can fix the base on the ground through the positioning screws, thereby preventing the base from sliding or shaking, thereby ensuring the safety of construction.

[0008] Furthermore, according to the jacking construction system for prefabricated buildings according to claim 1, it is characterized in that two threaded holes are provided on the side plate.

[0009] Through the above arrangement, the number of positioning screws is increased by increasing the number of threaded holes, thereby expanding the range of positioning the base and further enhancing the positioning effect of the base.

[0010] Furthermore, two side grooves are provided on the side wall of the side plate, and the side grooves are communicated with the threaded holes; a sliding groove is provided on the side plate, and a slider is slidably connected in the sliding groove, and a first spring is provided between the slider and the sliding groove: two limit blocks are provided on the slider, and an arc groove for resisting the positioning screw is provided at the end of the limit block away from the slider, and the limit block is slidably connected to the side groove; and it also includes a power mechanism for driving the two sliders to slide.

[0011] Through the above-mentioned arrangement, the two sliders are driven to move by the power mechanism, so that the slider moves along the path of the slide groove and the first spring is compressed; during the movement of the slider, the slider drives the limit block to move along the path of the side groove, that is, the limit block moves in the direction of the positioning screw, so that the arc groove on the limit block is against the positioning screw, and the arc groove wraps part of the positioning screw, thereby achieving the limitation of the positioning screw, and then preventing the positioning screw from swinging left and right, that is, strengthening the positioning effect of the base and preventing the base from sliding or shaking.

[0012] Furthermore, the power mechanism includes a bidirectional screw and linkage parts located on both sides of the bidirectional screw. The bidirectional screw is rotatably connected to the base. When the bidirectional screw rotates, the bidirectional screw drives the two sliders to slide through the two linkage parts.

[0013] Through the above arrangement, the bidirectional screw is driven to rotate, and the bidirectional screw drives the two sliders to slide through the two linkage parts.

[0014] Furthermore, the linkage part includes a first wedge block threadedly connected to the bidirectional screw and a second wedge block fixed to the slider. The first wedge block is provided with a guide rod, which is laterally slidably connected to the side plate. The second wedge block is located on the movement track of the second wedge block.

[0015] Through the above arrangement, during the rotation of the bidirectional screw, the two first wedge blocks approach each other, so that the first wedge block squeezes the second wedge block to drive the slider to slide along the path of the slide groove.

[0016] Furthermore, a worm is rotatably connected to both sides of the telescopic rod on the base, a first gear is fixed to the worm, and a second gear meshing with the first gear is fixed to the adjusting screw; a chamber is provided on both sides of the telescopic rod in the base, the worm extends into the chamber, and the bidirectional screw passes through the chamber; worm wheels are fixed to both ends of the bidirectional screw, and the worm wheels mesh with the worm.

[0017] Through the above arrangement, during the rotation of the adjusting screw, the adjusting screw will drive the second gear to rotate, the second gear meshes with the first gear to drive the first gear to rotate, the first gear drives the worm to rotate, the worm meshes with the worm wheel to drive the worm wheel to rotate, and the worm wheel drives the bidirectional screw to rotate.

[0018] Furthermore, the driving mechanism includes motors located on both sides of the telescopic rod, the motors are fixedly connected to the base, and the output shafts of the motors are fixedly connected to the adjusting screws.

[0019] Through the above arrangement, the output shaft of the motor drives the adjusting screw to rotate, so that the movable block moves vertically, and the movable block drives the top plate to move vertically, so that the telescopic rod is extended and retracted accordingly.

[0020] Furthermore, an inner chamber is provided in the side plate, and the inner chamber is communicated with the threaded hole; guide grooves are provided on both sides of the inner wall of the inner chamber, and guide blocks are slidably connected on both sides of the guide groove, and a second spring is provided between the guide block and the side wall of the guide groove; an elastic iron block is provided between the two guide blocks, which can be squeezed and compressed by two limit blocks at the same time, and the elastic iron block is arc-shaped, and the convex position of the elastic iron block is located between the two threaded holes.

[0021] Through the above-mentioned arrangement, during the movement of the two limit blocks on the single-side side plate, the limit blocks move in the direction of the elastic iron block, so that the limit blocks and the elastic iron block are against each other; the two limit blocks continue to move, and when the adjusting screw is positioned, the elastic iron block squeezed on the two limit blocks is compressed. At this time, the distance between the two guide blocks is reduced, and the second spring is stretched; therefore, the two second springs have reaction forces on the two guide blocks respectively, that is, the two second springs have reaction forces on both sides of the elastic iron block, and the elastic iron block itself also has a reaction force after being compressed. Therefore, the two reaction forces act on the two limit blocks at the same time through the elastic iron block, which can play a limiting role on the two limit blocks, thereby strengthening the limiting effect of the limit groove on the limit block on the positioning screw, that is, improving the stability of the positioning of the positioning screw.

[0022] Furthermore, a slope for squeezing the elastic iron block is provided on a side wall of one end of the limiting block away from the sliding block.

[0023] Through the above arrangement, the inclined surface can help the limiting block to squeeze the elastic iron block more smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The specific implementation process is as follows:

[0035] When in use, the base 10 is placed at a specified position, and multiple positioning screws 502 are rotated one by one. The positioning screws 502 move downward along the path of the threaded hole 501, so that the positioning screws 502 drill into the ground, thereby fixing the base 10 on the ground to prevent the base 10 from sliding or shaking; and, at this time, the positioning screws 502 are located on the movement trajectory of the limit block 51, so that the arc groove 511 on the limit block 51 can be against the positioning screw 502.

[0036] The height of the top plate 20 is adjusted according to the needs of use. The specific adjustment method is: start the motor 42, the output shaft of the motor 42 drives the adjusting screw 40 to rotate, so that the movable block 41 moves upward, and the movable block 41 drives the top plate 20 to move upward, so that the telescopic rod 30 is stretched; when the top plate 20 moves upward to the specified position, turn off the motor 42, so as to achieve the positioning of the adjusting screw 40 and the movable block 41, and then achieve the positioning of the top plate 20; because the motor 42, the adjusting screw 40 and the movable block 41 are provided on both sides of the telescopic rod 30, the force on both sides of the top plate 20 is uniform, that is, the vertical movement of the top plate 20 is smoother.

[0037] During the rotation of the adjusting screw 40, the adjusting screw 40 drives the second gear 82 to rotate, the second gear 82 meshes with the first gear 81 to drive the first gear 81 to rotate, the first gear 81 drives the worm 80 to rotate, the worm 80 meshes with the worm wheel 84 to drive the worm wheel 84 to rotate, the worm wheel 84 drives the bidirectional screw 70 to rotate, so that the first wedge block 71 moves toward the direction of the base 10, that is, the two first wedge blocks 71 approach each other; when the first wedge block 71 moves toward the direction of the base 10, the first wedge block 71 also moves toward the direction of the second wedge block 72 at this time, so that the first wedge block 71 The second wedge block 72 is squeezed to drive the slider 505 to slide along the sliding path, and the slider 505 drives the limit block 51 to move in the direction of the positioning screw 502, and the first spring 506 is compressed; the first wedge block 71 continues to move, and when the adjusting screw 40 is positioned, the arc groove 511 on the limit block 51 is against the positioning screw 502, and the arc groove 511 partially wraps the positioning screw 502, so as to achieve the limitation of the positioning screw 502, and then prevent the positioning screw 502 from swinging left and right, that is, to enhance the positioning effect of the base 10 and prevent the base 10 from sliding or shaking.

[0038] During the movement of the two limit blocks 51 on the single-sided side plate 50, the inclined surface 512 on the limit block 51 moves in the direction of the elastic iron block 93, so that the inclined surface 512 and the elastic iron block 93 are against each other; the two limit blocks 51 continue to move, and when the adjusting screw 40 is positioned, the inclined surfaces 512 on the two limit blocks 51 squeeze and compress the elastic iron block 93. At this time, the spacing between the two guide blocks 91 is reduced, and the second spring 92 is stretched; therefore, the two second springs 92 respectively have reaction forces on the two guide blocks 91, that is, the two second springs 92 have reaction forces on the two sides of the elastic iron block 93, and the elastic iron block 93 itself also has a reaction force after being compressed. Therefore, the two reaction forces act on the two limit blocks 51 at the same time through the elastic iron block 93, which can limit the two limit blocks 51, thereby strengthening the limiting effect of the limiting groove on the limit block 51 on the positioning screw 502, that is, improving the stability of the positioning of the positioning screw 502.
