Description

Technical Field

[0001] The invention relates to the technical field of electric power construction, and in particular to a comprehensive working platform for building facades. Background Art

[0002] Building facade refers to the outer enclosure of the building except the roof. The construction of building facade plays an important role in the infrastructure construction of substations, accounting for about 13% of the civil engineering cost, 18% of the civil engineering volume, and 22% of the total construction period of the substation project.

[0003] The construction content of the building facade mainly includes the installation of prefabricated wall panels, the construction of roof parapets, and the construction of exterior wall decoration. In the infrastructure project of the substation, the facade construction usually requires construction workers to work in an open position. The current construction practice usually adopts scaffolding-assisted method or ground vehicle-assisted method. Among them, the scaffolding-assisted method is to build a working space for construction workers by setting up scaffolding. In this process, it is necessary to complete the treatment of underground structures and ground sites before setting up scaffolding. Not only is the operation period long, but the setting up specifications are complicated, resulting in greater pressure on safe and civilized construction. The ground vehicle-assisted method uses ground vehicles as space transfer tools to transport people, materials, machines, etc. to the work location, and then carry out related operations. However, before the vehicle is used, the treatment of underground structures and ground sites still needs to be completed.

[0004] During the implementation process, the inventors found that the above-mentioned prior art has at least the following defects: when constructing the building facade, the ground site needs to be cleaned, which will affect the construction progress and lead to low construction efficiency. Summary of the invention

[0005] The embodiment of the present application solves the problem of low construction efficiency during building facade construction in the prior art by providing a comprehensive building facade operation platform.

[0006] In order to solve the above technical problems, the present invention adopts the following technical scheme: a comprehensive working platform for the building facade, including a workbench, an electric-driven mobile platform that can be placed on the roof, and a telescopic arm that can extend out of the building facade. The electric-driven mobile platform includes a chassis, and mobile steering wheels are installed at the four corners below the chassis. A support frame is fixed above the chassis; the rear part of the telescopic arm is fixed to the top of the support frame, and the front end of the telescopic arm suspends the workbench through a working steel wire rope.

[0007] When using this work platform for building facade construction, the electric-driven mobile platform can be placed on the indoor roof, and the telescopic arm drives the workbench to extend, so that workers can work on the workbench. Since the electric-driven mobile platform can be placed on the indoor roof, and the telescopic arm extends from indoor to outdoor, there is no need to clean the ground site, which improves construction efficiency.

[0008] Furthermore, a slide rail is installed on the top of the support frame, which extends out of the top of the support frame and is consistent with the extension direction of the telescopic arm; an electric hoist is installed on the slide rail; the electric hoist can lift materials used for the construction of the building facade, and the slide rail and the electric hoist can cooperate to lift materials to the workbench at any time, providing convenience for construction.

[0009] Furthermore, lifting legs that can be raised and lowered are respectively installed at the four corner positions below the chassis. Since the lifting legs can be raised and lowered, when the lifting legs are retracted, the chassis can be moved by moving the steering wheel to contact the roof. When the lifting legs are extended, the chassis can be lifted to avoid the moving steering wheel from contacting the roof, thereby improving the stability of the chassis.

[0010] Furthermore, the telescopic arm includes a servo electric cylinder, an outer cylinder fixed to the top of the support frame, and an inner cylinder installed in the outer cylinder; when the servo electric cylinder is extended, the inner cylinder can be extended relative to the outer cylinder.

[0011] Furthermore, the inner cylinder includes a first telescopic section and a second telescopic section nested outside the first telescopic section, and the outer cylinder is nested outside the second telescopic section; the servo electric cylinder includes a first electric cylinder and a second electric cylinder, wherein the first electric cylinder can drive the first telescopic section to extend relative to the second telescopic section, and the second electric cylinder can drive the second telescopic section to extend relative to the outer cylinder; since the inner cylinder includes the first telescopic section and the second telescopic section, the telescopic arm can be more flexible in extension and retraction, which is convenient for construction operations.

[0012] Furthermore, a support seat A is fixed to the rear end of the outer cylinder, a support seat B is fixed to the front end of the outer cylinder, a support seat C is fixed to the front end of the second telescopic section, and a support seat D is fixed to the front end of the first telescopic section; wherein the support seat B and the support seat C are both provided with through holes for the servo electric cylinder to pass through, the first electric cylinder passes through the through hole on the support seat C and its two ends are respectively fixed to the support seat B and the support seat D, the second electric cylinder passes through the through hole on the support seat B and its two ends are respectively fixed to the support seat A and the support seat C; thereby, by controlling the extension of the first electric cylinder and the second electric cylinder, the telescopic arm can be driven to extend, the structure is simple and the reliability is high.

[0013] Furthermore, a transverse rod is fixed to the front end of the telescopic arm, and both ends of the transverse rod are suspended on both sides of the workbench through working steel wire ropes; a lifting mechanism is fixed on both sides of the workbench, and the output end of the lifting mechanism is connected to the lower end of the working steel wire rope.

[0014] Furthermore, safety locks are fixed on both sides of the workbench. Correspondingly, safety ropes are hung at both ends of the transverse rod, and the lower end of the safety rope is fixed to the safety lock on the corresponding side. The safety rope can provide safety protection for the workbench and reduce safety hazards.

[0015] It can be seen from the above technical solutions that the present invention has at least the following technical effects or advantages: When using this work platform for the construction of the building facade, the electric-driven mobile platform can be placed on the indoor roof, and the telescopic arm drives the workbench to extend, so that the staff can work on the workbench. Since the electric-driven mobile platform can be placed on the indoor roof, and the telescopic arm extends from indoor to outdoor, there is no need to clean the ground site, which improves the construction efficiency. The electric hoist can hoist the materials used for the construction of the building facade. The slide rail and the electric hoist can be used to hoist the materials to the workbench at any time, providing convenience for construction. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0019] The present invention discloses a comprehensive building facade operation platform, such as Figure 1 As shown, it includes an electric-driven mobile platform 1, a support frame 2, a telescopic arm 3 and a workbench 4. The support frame 2 is installed above the electric-driven mobile platform 1, the telescopic arm 3 is fixed above the support frame 2, and the workbench 4 is suspended at the front end of the telescopic arm 3 through a working steel wire rope 5. In one example, the electric-driven mobile platform 1 is located indoors, and the front end of the telescopic arm 3 is outdoors after being extended, and construction workers can perform work on the building facade on the workbench 4.

[0020] like Figure 2 As shown, the electric drive mobile platform 1 includes a chassis 6, a movable steering wheel 7 and a lifting leg 8. There are four movable steering wheels 7, which are respectively installed at the positions near the four corners below the chassis 6. Each movable steering wheel 7 is controlled by two motors. Figure 3 As shown, each mobile steering wheel 7 includes two rollers, which are connected by a transmission shaft, and the transmission shaft can be driven by a motor to realize the rotation of the rollers. The transmission shaft is installed at the bottom of the chassis 6 through a rotating shaft, and a gear is also installed on the upper end of the rotating shaft. When another motor rotates, the torque of its output shaft can be transmitted to the rotating shaft through the gear, thereby driving the rotating shaft to rotate to realize the steering of the two rollers. In this way, each mobile steering wheel 7 can provide traction for the chassis 6 and can steer independently, so that the chassis 6 can move more flexibly.

[0021] The jacking legs 8 are also installed with four, and the four jacking legs 8 are respectively located at the four corners below the chassis 6. When the jacking legs 8 are in the retracted state, the movable steering wheel 7 can contact the roof to facilitate the movement of the device. When the jacking legs 8 are in the extended state, the chassis 6 is propped up under the action of the jacking legs 8, and the movable steering wheel 7 is in a suspended state to facilitate the fixation of the device.

[0022] The support frame 2 is a frame-like structure. Figure 1As shown, in this embodiment, the support frame 2 adopts a standardized tower crane standard section, so it has strong versatility and is conducive to reducing costs. The bottom of the support frame 2 is fixed to the upper surface of the electric drive mobile platform 1 by bolt connection or welding. The support frame 2 can fix the telescopic arm 3 at a certain height above the electric drive mobile platform 1, so that when the workbench 4 is suspended below the front end of the telescopic arm 3, it is convenient for construction workers to work on the workbench 4.

[0023] The telescopic arm 3 includes an outer cylinder 9, an inner cylinder 10 and a servo electric cylinder. The outer cylinder 9 is fixed to the top of the support frame 2, and the inner cylinder 10 is located inside the outer cylinder 9 and can move relative to the inner cylinder 10. The telescopic movement of the inner cylinder 10 relative to the outer cylinder 9 is achieved by driving the servo electric cylinder. Figure 1 , Figure 4 As shown, the inner cylinder 10 includes a first telescopic section 11 and a second telescopic section 12, the second telescopic section 12 is nested outside the first telescopic section 11, and the outer cylinder 9 is nested outside the second telescopic section 12. The servo electric cylinder includes a first electric cylinder 13 and a second electric cylinder 14, wherein the first electric cylinder 13 can drive the first telescopic section 11 to extend relative to the outer cylinder 9, and the second electric cylinder 14 can drive the second telescopic section 12 to extend relative to the outer cylinder 9.

[0024] More specifically, a support seat A15 is fixed to the rear end of the outer cylinder 9, a support seat B16 is fixed to the front end of the outer cylinder 9, a support seat C17 is fixed to the front end of the second telescopic section 12, and a support seat D18 is fixed to the front end of the first telescopic section 11. Among them, the support seats B16 and C17 are both provided with through holes for the servo electric cylinder to pass through, the first electric cylinder 13 passes through the through hole on the support seat C17 and its two ends are respectively fixed to the support seat B16 and the support seat D18, and the second electric cylinder 14 passes through the through hole on the support seat B16 and its two ends are respectively fixed to the support seat A15 and the support seat C17.

[0025] When the telescopic arm 3 is in the extended state, the first telescopic section 11 is the front part of the telescopic arm 3, and the workbench 4 is suspended at the front end of the first telescopic section 11 through the working wire rope 5. Figure 1 As shown, a transverse rod 19 is fixed to the front end of the telescopic arm 3, and the two ends of the transverse rod 19 are respectively suspended on both sides of the workbench 4 through the working wire rope 5. Therefore, when the telescopic arm 3 is extended, the workbench 4 can be driven to move. In addition, a lifting mechanism 20 is fixed on both sides of the workbench 4, and the output end of the lifting mechanism 20 is connected to the lower end of the working wire rope 5. In this embodiment, the lifting mechanism 20 includes a hoisting motor, and the output end of the hoisting motor winds the lower end of the working wire rope 5, thereby controlling the rotation of the hoisting motor to realize the rise or fall of the electric-driven mobile platform 1.

[0026] like Figure 5 As shown, safety locks 21 are fixed on both sides of the workbench 4, and safety ropes 24 are hung at both ends of the transverse rod 19. The lower ends of the safety ropes 24 are locked and fixed to the safety locks 21, thereby improving the safety of the workbench 4 and avoiding accidents.

[0027] On the other hand, a slide rail 22 is also installed on the top of the support frame 2, and the extension direction of the slide rail 22 is consistent with the extension direction of the telescopic arm 3. An electric hoist 23 is installed on the slide rail 22, and its front end extends out of the support frame 2. Therefore, materials can be lifted to the workbench 4 at any time through the electric hoist 23, which is convenient for construction.
