[0002] The vertical installation method is usually used for the installation of duct risers in super high-rise buildings. The construction sequence is to connect and install them one by one from bottom to top. The duct sections need to be transported horizontally to the duct well on each floor. This vertical installation method requires multiple vertical and horizontal transportation of the ducts.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-7 The utility model provides a technical solution: a pipe riser hoisting device for a high-rise building engineering shaft, comprising a concave frame 1 and a gantry 2, wherein the gantry 2 is fixed to the upper end of the concave frame 1, a through opening 17 is opened in the middle of the concave frame 1, and push plates 3 are arranged on both sides of the lower end of the concave frame 1, support plates 19 are fixed to the lower ends of the push plates 3, a plurality of support rollers 6 are rotatably connected to the upper ends of the support plates 19, and a V-shaped clamping plate 8 is fixed to the inner side wall of the push plate 3, a first synchronous cylinder 4 is connected between the inner side wall of the concave frame 1 and the push plate 3, a first storage battery 16 is installed on the upper end of the concave frame 1, and the forward and reverse motors 14 and the first synchronous cylinder 4 are electrically connected to the first storage battery 16.

[0028] When the engineering pipe is hoisted by the hoisting device, the engineering pipe is passed through the opening 17 and placed on two support plates 19. At this time, the engineering pipe is supported by the support rollers 6 on the support plates 19. Since the first battery 16 is electrically connected to the first synchronous cylinder 4, the extension of the first synchronous cylinder 4 drives the push plate 3 and the V-shaped clamping plate 8 to approach the outer wall of the engineering pipe. During this process, the support rollers 6 will rotate along the lower end of the engineering pipe, so that the V-shaped clamping plate 8 can smoothly clamp and fix the engineering pipe to prevent the engineering pipe from tipping over.

[0029] In this embodiment, two telescopic shafts 5 are connected between the inner side wall of the concave frame 1 and the push plate 3, and the lower end of the support plate 19 is rotatably connected to a plurality of rotating rollers 7.

[0030] When the rotating roller 7 is supported on the ground and the push plate 3 drives the rotating roller 7 to move along the ground, the rotation of the rotating roller 7 is conducive to ensuring the smoothness of the movement of the push plate 3, and a telescopic shaft 5 is arranged between the inner side of the concave frame 1 and the push plate 3. The telescopic shaft 5 will be extended and retracted along with the extension and retraction of the first synchronous cylinder 4, and the telescopic shaft 5 will share the bearing force of the first synchronous cylinder 4, thereby ensuring the stability of the push plate 3 when supporting the engineering pipe.

[0031] In this embodiment, a pressure plate 10 is slidably sleeved on the outer periphery of the gantry 2, and a lifting drive assembly is provided above the concave frame 1, and the lifting drive assembly includes a forward and reverse motor 14 and a screw rod 15, the forward and reverse motor 14 is fixed to the upper end of the concave frame 1, one end of the screw rod 15 is connected to the power end of the forward and reverse motor 14, and the other end of the screw rod 15 is rotatably connected to the top end of the gantry 2, the pressure plate 10 is threadedly sleeved with the screw rod 15, and a lifting ring 9 is fixed to the middle part of the upper end of the gantry 2.

[0032] And the screw rod 15 is driven to rotate through the work of the forward and reverse motor 14, and the screw rod 15 will drive the pressure plate 10 to slide downward along the gantry 2 until the pressure plate 10 is pressed on the engineering pipe, and the lifting ring 9 is lifted by a crane and the lifting device is driven to perform the lifting work. In summary, the engineering pipe is clamped and positioned from top to bottom during the lifting process, and is also clamped and positioned on both sides through the clamping of the V-shaped clamp plate 8, which is beneficial to ensure the stability of the engineering pipe during the lifting process.

[0033] In this embodiment, a positioning rod 11 is fixed in the middle of the lower end of the pressure plate 11, and second synchronous cylinders 12 are fixed around the periphery of the positioning rod 11. The power ends of the second synchronous cylinders 12 are connected to positioning wheels 13. A second battery 18 is installed at the upper end of the pressure plate 10, and the second synchronous cylinders 12 are electrically connected to the second battery 18.

[0034] When the pressure plate 10 is pressed on the engineering pipe, the positioning rod 11 will drive the second synchronous cylinder 12 and the positioning wheel 13 to insert into the inner periphery of the engineering pipe, and the second synchronous cylinder 12 will be powered by the second battery 18. The positioning wheel 13 will be driven to press against the inner wall of the engineering pipe through the extension of the first synchronous cylinder 4, and the four positioning wheels 13 will press against the inner wall of the engineering pipe at the same time. In the process of lowering the engineering pipe, the first synchronous cylinder 4 will be contracted to facilitate the convenient and quick driving of the push plate 3 away from the bottom of the engineering pipe, which effectively solves the trouble of manual operation and makes the installation process of the engineering pipe safer. When the support roller 6 no longer supports the engineering pipe, the V-shaped clamping plate 8 no longer clamps the engineering pipe. At this time, during the lowering and installation of the engineering pipe, the positioning wheel 13 rotates along the inner wall of the engineering pipe. Therefore, the four positioning wheels 13 are conducive to the smooth lowering and installation of the engineering pipe, avoiding the occurrence of skewness during the lowering and installation of the engineering pipe, and are conducive to the accurate installation of the engineering pipe, effectively ensuring the installation quality.

[0035] Working principle:

[0036] When the engineering pipe is hoisted by the hoisting device, the engineering pipe is passed through the through hole 17 and placed on the two push plates 3. At this time, the engineering pipe is supported by the support rollers 6 on the push plate 3, and the push plate 3 and the V-shaped clamping plate 8 are driven to approach the outer wall of the engineering pipe by the extension of the first synchronous cylinder 4 until the V-shaped clamping plate 8 clamps the engineering pipe and fixes it. Then, the screw rod 15 is driven to rotate by the work of the forward and reverse motor 14, and the screw rod 15 will drive the pressing plate 10 to slide downward along the gantry 2 until the pressing plate 10 is pressed on the engineering pipe. At the same time, the positioning rod 11 will drive the second synchronous cylinder 12 and the positioning wheel 13 to insert into the inner periphery of the engineering pipe, and then the positioning wheel 13 is driven to press against the inner wall of the engineering pipe by the extension of the first synchronous cylinder 4. When the engineering pipe is lowered and installed, the first synchronous cylinder 4 is first contracted to facilitate the convenient and quick driving of the push plate 3 away from the bottom of the engineering pipe. At the same time, the V-shaped clamping plate 8 no longer clamps the engineering pipe, and the positioning wheel 13 rotates along the inner wall of the engineering pipe until the engineering pipe is lowered and installed.
