Description

Technical Field

[0001] The utility model relates to the technical field of assembled composite floor slabs, in particular to assembled composite floor slab construction equipment. Background Art

[0002] Prefabricated composite floor slabs are assembled integral floor slabs made of precast panels and cast-in-place reinforced concrete layers. The precast panels are both one of the components of the floor slab structure and the permanent formwork of the cast-in-place reinforced concrete composite layer. Horizontal equipment pipelines can be laid in the cast-in-place composite layer. The composite floor slabs have good integrity and high rigidity, which can save formwork. The span of the composite floor slabs is generally four to six meters, and the maximum span can reach nine meters. During the floor slab construction, a lifting device is required to transport the floor slabs to the appropriate floor position.

[0003] For example, the public document with application number 202321464097.2 discloses an assembled composite floor construction equipment. The utility model drives the bevel screw through the screw motor to drive the four threaded cone rods to rotate, and the two translation seats move towards or back to adjust the left and right spacing of the four support plates. Then, four stepper motors are used to drive the stepping belt through the shaft to adjust the front and back spacing of the four support plates. The support plates are fixedly connected to the stepping belt. When the limit plate clamps the prefabricated composite plate, the support plates remain relatively fixed and will not move, thereby achieving The effect of fixing the floor slab structure is adjusted according to the length and width of the composite floor slab. However, when hoisting the floor slab, the prefabricated composite floor slab construction equipment only clamps and fixes the periphery of the floor slab through a horizontal surface. If the clamping friction becomes weak during hoisting and transportation, it is very likely to cause the floor slab to fall off from the bottom, making it difficult to ensure the safety and stability of the clamping and fixing transportation. At the same time, if you want to ensure the stability of the clamping and transportation, you must increase the clamping force. Excessive clamping force may cause the floor slab to break and be damaged, thereby affecting the use of the floor slab.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an assembled composite floor construction equipment is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide an assembled composite floor slab construction device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled composite floor construction equipment, including a lifting and connecting platform, four connecting arms are symmetrically distributed and rotatably installed on the left and right sides of the surface of the lifting and connecting platform, the bottom end of the connecting arm is rotatably provided with the same assembly lifting platform, an adjustment mechanism is provided below the inner surface of the assembly lifting platform, and splints are provided at the four corners below the adjustment mechanism, the splint is arranged in an "L" shape, and an anti-slip mechanism is installed on the inner surface of the splint.

[0007] Preferably, the adjustment mechanism includes a bidirectional threaded push rod which is arranged to rotate laterally on the inner surface of the assembly platform.

The left and right sides of the surface of the bidirectional threaded push rod are threadedly connected with a movable seat.

[0008] Preferably, the adjustment mechanism also includes a connecting frame fixedly installed on the lower surface of the movable seat, and a bidirectional screw is longitudinally rotated installed on the inner surface of the connecting frame.

[0009] Preferably, the adjustment mechanism further comprises a bidirectional screw whose front and rear sides are both threadedly connected to the adjustment seat, and a clamping plate is fixedly mounted on the lower surface of each adjustment seat.

[0010] Preferably, the anti-slip mechanism includes springs fixedly mounted on the inner surfaces of both sides of the splint, a pressure block fixedly mounted on one end of the spring close to the inner side of the splint, and the pressure block slides through the splint.

[0011] Preferably, the anti-slip mechanism also includes a movable rod rotatably installed on the lower surface of one end of the splint where the pressure block is located. The middle part of the movable rod is connected to the inner surface of the splint at a fixed point by a shaft rod that is arranged through it.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is provided with an adjusting mechanism, a bidirectional threaded push rod, a driving motor, a movable seat, a connecting frame, a bidirectional screw, a synchronous motor, an adjusting seat and a clamping plate. The driving motor can drive the bidirectional threaded push rod to rotate, and under the limit of the assembly hanging platform slot body, the movable seat drives the entire connecting frame device to move left and right, and the synchronous motor can drive the bidirectional screw to rotate. Under the limit of the connecting frame slot body, the adjusting seat can move back and forth and adjust, so that the clamping plate can adapt to composite floor slabs of different lengths and widths for clamping and fixing, and then the entire assembly hanging platform can use the adjusting mechanism to flexibly adjust the clamping length and clamping width of the clamping plate, thereby achieving the effect of adjusting and fixing the floor slab structure according to the length and width of the composite floor slab;

[0015] 2. The utility model is provided with an anti-slip mechanism, a spring, a pressure block, a movable rod and a supporting plate. When the splint clamps and fixes the long and wide edges at the four corners of the floor slab, as the splint is retracted, the long and wide side walls at the four corners of the floor slab will squeeze the pressure block to shrink into the inside of the splint, and the squeezing spring will shrink. At this time, the movable rod will use the shaft rod to rotate at a fixed point, so that the upper and lower ends rotate in opposite directions, that is, the lower end of the movable rod will push the supporting plate to extend, and the floor slab will be shoveled and lifted by the inclined surface. The supporting plate can limit the lower surface of the floor slab, making the floor slab more stable during the lifting and transportation process, and effectively avoiding insufficient clamping friction, which causes the floor slab to slip and fall from the bottom. In addition, with the provision of this mechanism, no excessive clamping force is required during the clamping process, which can also ensure the stability of the floor slab and prevent the floor slab from being broken or damaged due to excessive clamping force.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 2 As shown, an assembled composite floor construction equipment includes a lifting and connecting platform 1, four connecting arms 2 are symmetrically distributed and rotatably installed on the left and right sides of the surface of the lifting and connecting platform 1, the bottom end of the connecting arm 2 is rotatably provided with the same assembly lifting platform 3, an adjustment mechanism 4 is provided below the inner surface of the assembly lifting platform 3, and splints 5 are provided at the four corners below the adjustment mechanism 4. The splints 5 are arranged in an "L" shape, and an anti-slip mechanism 6 is installed on the inner surface of the splint 5.

[0022] By adopting the above technical solution, the lifting device can pull up the entire equipment using the lifting connection platform 1;

[0023] The "L"-shaped clamping plate 5 can ensure that the length and width of the four corners of the floor are covered and clamped at the same time.

[0024] Furthermore, the adjustment mechanism 4 includes a bidirectional threaded push rod 401 which is arranged to rotate laterally on the inner surface of the assembly platform 3. The right end of the bidirectional threaded push rod 401 passes through the assembly platform 3 and is provided with a drive motor 402. The drive motor 402 is fixedly connected to the right side of the outer surface of the assembly platform 3. The left and right sides of the surface of the bidirectional threaded push rod 401 are threadedly connected to a movable seat 403.

[0025] Furthermore, the adjustment mechanism 4 also includes a connecting frame 404 fixedly installed on the lower surface of the movable seat 403, and a bidirectional screw 405 is longitudinally rotated on the inner surface of the connecting frame 404. The front end of the bidirectional screw 405 passes through the connecting frame 404 and is provided with a synchronous motor 406. The synchronous motor 406 is fixedly connected to the front end of the outer surface of the connecting frame 404.

[0026] Furthermore, the adjustment mechanism 4 also includes a bidirectional lead screw 405 whose front and rear sides are both threadedly connected to the adjustment seat 407 , and a clamping plate 5 is fixedly mounted on the lower surface of each adjustment seat 407 .

[0027] By adopting the above technical solution, the driving motor 402 can drive the bidirectional threaded push rod 401 to rotate, and under the limitation of the groove body of the assembly platform 3, the moving seat 403 drives the entire connecting frame 404 device to move left and right for adjustment, and the synchronous motor 406 can drive the bidirectional screw 405 to rotate, and under the limitation of the groove body of the connecting frame 404, the adjustment seat 407 can move back and forth for adjustment, so that the splint 5 can adapt to composite floor slabs of different lengths and widths for clamping and fixing.

[0028] like Figure 2-Figure 3 As shown, the anti-slip mechanism 6 includes springs 601 fixedly mounted on the inner surfaces of both sides of the splint 5 , and a pressure block 602 is fixedly mounted on one end of the spring 601 close to the inner side of the splint 5 , and the pressure block 602 slides through the splint 5 .

[0029] Furthermore, the anti-slip mechanism 6 also includes a pressure block 602 and a movable rod 603 rotatably installed on the lower surface of one end of the splint 5. The middle part of the movable rod 603 is connected to the inner surface of the splint 5 at a fixed point by a shaft rod that is set through it. The upper and lower ends of the movable rod 603 are both retractable.

[0030] By adopting the above technical solution, the upper and lower ends of the movable rod 603 can be extended and retracted. When the movable rod 603 rotates at a fixed point, the extension and retraction of the upper and lower ends can compensate for the horizontal line difference caused by the arc movement, thereby ensuring that the pressure block 602 and the support plate 604 both perform stable horizontal movement.

[0031] Furthermore, the anti-slip mechanism 6 also includes a supporting plate 604 rotatably connected to the lower end of the movable rod 603 . The upper surface of the supporting plate 604 is set as an inclined surface, and the supporting plate 604 slides through the splint 5 .

[0032] By adopting the above technical solution, when the splint 5 clamps and fixes the long and wide edges at the four corners of the floor slab, as the splint 5 is retracted, the long and wide side walls at the four corners of the floor slab will squeeze the pressure block 602 to shrink towards the inside of the splint 5, and the extrusion spring 601 will shrink. At this time, the movable rod 603 will use the axis rod to rotate at a fixed point, so that the upper and lower ends rotate in opposite directions, that is, the lower end of the movable rod 603 will push the support plate 604 to extend, and use the inclined surface to shovel and lift the floor slab. The support plate 604 can limit the lower surface of the floor slab, making the floor slab more stable during the lifting and transportation process, and effectively avoiding insufficient clamping friction, which causes the floor slab to slip and fall from the bottom.

[0033] Working principle: When using the assembled composite floor construction equipment, first, the entire assembly platform 3 is covered above the floor, and then the driving motor 402 and the synchronous motor 406 are used to adjust the distance between the splints 5 according to the length and width of the floor. The driving motor 402 can drive the two-way threaded push rod 401 to rotate, and under the limit of the assembly platform 3 slot body, the moving seat 403 drives the entire connecting frame 404 device to move left and right, and the synchronous motor 406 can drive the two-way screw 405 to rotate, and under the limit of the connecting frame 404 slot body, the adjusting seat 407 is moved back and forth to adjust, so that the splint 5 can adapt to composite floors of different lengths and sizes for clamping and fixing. After the length and width are adjusted to the four corners of the floor, the length and width sides can be just slightly located on the inside of the splint 5, and then the splint 5 is synchronized. The final length and width distance is tightened, so that the plywood 5 clamps and fixes the floor slab. When the plywood 5 clamps and fixes the length and width edges at the four corners of the floor slab, as the plywood 5 is retracted, the length and width side walls at the four corners of the floor slab will squeeze the pressure block 602 to shrink into the inside of the plywood 5, and the extrusion spring 601 will shrink. At this time, the movable rod 603 will use the shaft rod to rotate at a fixed point, so that the upper and lower ends rotate in opposite directions, that is, the lower end of the movable rod 603 will push the supporting plate 604 to extend, and use the inclined surface to shovel and lift the floor slab. The supporting plate 604 can limit the lower surface of the floor slab, making the floor slab more stable during the lifting and transportation process. After the floor slab is fixed, the entire equipment can be pulled up by using the lifting device and the lifting connection platform 1 to lift and transport the floor slab. This is the working principle of the assembled composite floor slab construction equipment.
