Description

Technical Field

[0001] The utility model relates to a mobile operating platform, in particular to a mobile operating platform suitable for reverse hanging construction of roof structures. Background Art

[0002] Reverse hanging is a common operation method in roof structure construction. It has been widely used because of its advantages such as efficient lifting of components (components can be lifted from bottom to top to increase the lifting height), easy component installation and no restrictions on working space (suitable for narrow construction sites, etc.). At present, when implementing reverse hanging construction, the conventional practice is to build a scaffold under the roof working surface, and then install a movable operating platform on the scaffold, and then the roof personnel stand on the operating platform to perform reverse hanging construction on the roof. From the actual implementation, it can be found that building scaffolds requires a lot of manpower and material resources, wastes pipes seriously, increases construction costs, and scaffolds occupy the civil construction working surface. Due to the limitation of working space, civil construction operations cannot be carried out simultaneously with roof operations, which slows down the construction speed. In addition, there are great safety hazards in scaffolding, which shows that there is room for improvement. Utility Model Content

[0013] In actual implementation, a pair of wheels 13 is installed on each wheel seat 11. The pair of wheels 13 serving as active wheels are connected to a travel drive motor (not shown in the figure) via a transmission mechanism (not shown in the figure). The travel drive motor is installed on the wheel seat 11. The pair of wheels 13 are driven to rotate via the transmission mechanism under the drive of the travel drive motor to achieve forward and backward movement on the guide rail 50. The pair of wheels 13 on the other wheel seat 11 serve as driven wheels and are not connected to the travel drive motor.

[0014] Furthermore, the transmission mechanism may include a driving gear and a driven gear, wherein the driving gear is mounted on the output shaft of the travel drive motor, and the driven gear is mounted on the axle between the pair of wheels 13. The driving gear rotates under the drive of the travel drive motor, and the driven gear rotates under the drive of the driving gear, and then the driven gear drives the wheels 13 to rotate via the axle. In practice, the driving gear and the driven gear may be meshed and connected to each other, or the two may be connected by a chain.

[0015] The transmission mechanism can also be designed in other forms without limitation.

[0016] like Figure 2 The connecting member 20 includes a load-bearing cross bar 21, the middle part of which is fixedly connected to the wheel seat 11 through an L-shaped fixing plate 22. The load-bearing cross bar 21 extends horizontally from the two ends of the existing cross beam 60, and is respectively fixedly connected to the top of a load-bearing vertical bar 24 through an upper connecting plate 23. The bottom end of each load-bearing vertical bar 24 is respectively fixedly connected to an assembly plate 26 through a lower connecting plate 25, wherein: each load-bearing vertical bar 24 is close to the existing cross beam 60 but not in contact with it; the assembly plate 26 is located below the existing cross beam 60 and is used to install the lifting device 30.

[0017] In the actual design, the load-bearing cross bar 21 and the load-bearing vertical bar 24 are made of I-beams, wherein: the lower flange plate of the I-beam used to make the load-bearing cross bar 21 is provided with a middle notch 211 in the middle part and side notches 212 on both sides; the L-shaped fixing plate 22 is placed in the middle notch 211 and is detachably connected to the load-bearing cross bar 21 and the connecting rod 12 through the fixing bolt assembly 220; the upper connecting plate 23 is placed in the side notch 212 and is detachably connected to the load-bearing cross bar 21 and the load-bearing vertical bar 24 through the upper bolt assembly 230; the lower connecting plate 25 is detachably connected to the assembly plate 26 through the lower bolt assembly 250.

[0018] The I-beam is usually composed of a web and upper and lower flange plates, which are connected to the web to form an I-shape. Furthermore, the size of the middle notch 211 matches the size of the L-shaped fixing plate 22, the size of the side notch 212 matches the size of the upper connecting plate 23, and the size of the upper connecting plate 23 matches the size of the web of the load-bearing vertical rod 24.

[0019] To be more specific: the L-shaped fixing plate 22 is in the middle notch 211, one end of which is connected to the web of the stressed cross bar 21 and the other end is connected to the connecting rod 12; the upper connecting plate 23 is in the side notch 212, one end of which is connected to the web of the stressed cross bar 21 and the other end is connected to the web of the stressed vertical rod 24; one end of the lower connecting plate 25 is connected to the web of the stressed cross bar 21 and the other end is connected to the assembly plate 26.

[0020] In the present invention, the coordinated design of the L-shaped fixing plate 22, the upper connecting plate 23 and the lower connecting plate 25 with the load-bearing crossbar 21 and the load-bearing vertical bar 24 made of I-beams greatly improves the overall structural stability of the connecting member 20 and ensures construction safety.

[0021] In actual design, the fixing bolt assembly 220, the upper bolt assembly 230, and the lower bolt assembly 250 all include bolts and nuts. The purpose of their design is to assemble and adjust the load-bearing crossbar 21, the load-bearing vertical bar 24, and the assembly plate 26 on site according to the cross-sectional dimensions of the existing crossbeam 60. Specifically, on the one hand, the load-bearing crossbar 21 of appropriate length is selected according to the cross-sectional dimensions of the existing crossbeam 60, and on the other hand, the upper and lower positions of the load-bearing vertical bar 24 can be adjusted by installing the upper connecting plate 23 and the lower connecting plate 25, so that the assembly plate 26 can be placed under the existing crossbeam 60 without contact. In actual implementation, in order to facilitate adjustment, the length of the upper connecting plate 23 and the lower connecting plate 25 can be designed to be longer, and multiple holes for installing bolt assemblies can be opened on the upper and lower parts of the load-bearing vertical bar 24. In addition, the assembly plate 26 is usually designed to be of appropriate size according to the electric hoist.

[0022] The utility model can be disassembled and reassembled based on the above design, thereby realizing the turnover and repeated utilization of the mobile operating platform and reducing the construction cost.

[0023] In addition, the connecting rod 12 can also be made of I-beam, and the length of the connecting rod 12 is usually slightly smaller than the length of the cage 40.

[0024] like Figure 3 The lifting device 30 uses an electric hoist (such as a suspended electric hoist), wherein: the motors 31 of the two electric hoists are connected to a PLC controller, and the PLC controller is connected to the main controller to realize the synchronous control of the lifting of the two electric hoists by the main controller; the hook 34 of the electric hoist is a hook with an anti-drop function.

[0025] Specifically, the spring on the hook 34 is provided with an anti-drop card. When the lifting ring 44 of the cage 40 is hung on the hook 34, the anti-drop card locks the lifting ring 44 in the hook 34 to prevent the lifting ring 44 from falling off, thereby improving safety. The hook with the anti-drop function can be an existing hook in the art.

[0026] Electric hoists are commonly used equipment in this field. Usually, the electric hoist includes a motor 31, a winch 32, a wire rope 33, a hook 34, a winch control device and a safety protection device. In actual application, one side of the electric hoist is fixed to the assembly plate 26. Usually, the electric hoist is bolted to the assembly plate 26 through its own reserved bolt holes. The lifting ring 44 on the cage 40 is hung on the hook 34 of the electric hoist. Here, based on the design of the PLC controller, the two electric hoists can work synchronously. Therefore, the winch 32 is driven to rotate by the motor 31, and the cage 40 can be lifted or lowered by the wire rope 33.

[0027] In the present invention, the master controller can be a handheld remote controller, or it can be fixed on the cage 40 for operation by the operator. The master controller mainly includes a single chip microcomputer or a microprocessor. PLC controller and master controller are well-known technologies in the art and will not be described in detail here.

[0028] like Figure 1 Specifically, the cage 40 includes a steel frame formed by welding a crossbar 41 and a vertical bar 42, a steel springboard 43 is arranged on the bottom surface of the frame, and lifting rings 44 are welded on the top of both sides of the frame.

[0029] In actual design, the guide rail 50 is U-shaped, and limit blocks (not shown) are provided at both ends of the guide rail 50. The guide rail 50 is designed to prevent the wheels 13 from deflecting, and the limit blocks are used to limit the movement of the walking device 10 only within the working range.

[0030] like Figure 4 The two ends of the safety rope 70 are respectively fixed to the bottom of the existing cross beam 60 through anchors 80, and a section of the safety rope 70 is correspondingly arranged under each section of the guide rail 50. When the cage 40 rises to the working height, the safety belt worn by the operator in the cage 40 can be hung on the safety rope 70 to ensure the life safety of the operator.

[0031] In the present invention, the anchor 80 is used to fix the end of the safety rope 70 to the existing cross beam 60, which can be implemented by using well-known components in the art without limitation. On site, the safety rope 70 is hung under the existing cross beam 60. When the cage 40 rises to a certain height, the operator in the cage 40 must wear a safety belt and the safety belt must be hung on the safety rope 70 to ensure construction safety.

[0032] When in use, first select a load-bearing crossbar 21 of appropriate length according to the cross-sectional size of the existing crossbeam 60, then install the guide rail 50, install the running device 10 on the guide rail 50, and install and adjust the connecting member 20. Then, after the lifting device 30 is lifted to a suitable height by mechanical equipment, it is fixed to the assembly plate 26 by bolt connection. Then, the prepared cage 40 is hung on the hook 34 of the lifting device 30, and then the reverse lifting construction can begin.

[0033] During construction, the operator enters the cage 40 and fastens the safety belt. Then the two lifting devices 30 are raised and lowered synchronously through the main controller. When the cage 40 rises to the working height, the operator fastens the safety belt to the safety rope 70. Then, the operator in the cage 40 can work with the roofing personnel to carry out the reverse lifting construction of the roof structure, such as lifting the roof panel to the roof and fixing it with nails using an electric drill. When the construction of the roof panel at the current position is completed, the operator can control the walking device 10 through the main controller to move to the next working position on the existing beam 60 to install the next roof panel.

[0034] When the construction within the range of the guide rail 50 is completed, the cage 40 can be lowered to the civil construction work surface (ground), the lifting device 30, the connecting member 20, the walking device 10 and the guide rail 50 (the guide rail 50 can also be left) can be disassembled, and then transferred to another work site for reassembly and use.

[0035] The advantages of the utility model are:

[0036] The utility model eliminates the need for building scaffolding, and installation is achieved based on the completed crossbeams before the roof structure is constructed, which saves time and effort, does not occupy the civil construction working surface, is not restricted by the working space, and enables civil construction work and roofing work to be carried out simultaneously, thereby speeding up the construction speed, reducing the construction cost, ensuring construction safety, and convenient installation and disassembly, which can be used in a turnover manner, is applicable to crossbeams of various cross-sectional sizes, and is suitable for popularization.

[0037] The above are preferred embodiments of the present invention and the technical principles used therein. For those skilled in the art, without departing from the spirit and scope of the present invention, any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the present invention are within the protection scope of the present invention.
