Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to an automatically telescopic tool-type operating platform supporting a material placing machine in an elevator shaft. Background Art

[0002] At present, most aluminum film projects use lifting type concrete placing machines. However, in order to reduce the number of holes in the floor slabs, most of them use the elevator shaft as the opening for the lifting type concrete placing machines. The base of the concrete placing machine needs to be fixed two floors below the working area. The concrete placing machine derrick and horizontal protection in the elevator shaft are not ready for erection, resulting in safety hazards on the working floor in the elevator shaft.

[0003] There are three traditional practices for the above situation: ① Illegal operations, where workers climb the derrick of the concrete placing machine to perform operations; ② Using the derrick of the concrete placing machine to build a temporary operating platform. Since the steel pipes are tied to the derrick with iron wire, there is a complete hidden danger of the platform tipping over; ③ Forming a platform by building a steel pipe rack, and then dismantling the steel pipe rack after the aluminum film is installed.

[0004] In summary, the traditional process has disadvantages such as potential safety hazards, low efficiency, and complicated procedures. Therefore, in order to solve the above problems, an automatically retractable tool-type operating platform for the elevator shaft placing machine is specially designed and developed. Summary of the invention

[0005] The purpose of the present invention is to provide an automatically retractable tool-type operating platform for an elevator shaft material placing machine, and its purpose is to overcome the above-mentioned problems existing in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

The cross bar is fixedly connected between two adjacent movable supports to form one side surface of the movable support structure, and three support rods are evenly distributed on each side surface.

[0013] Furthermore, the above-mentioned outer frame includes a lower frame, an upper frame and columns, all of which are located above the fixed base. The four columns are fixedly arranged between the lower frame and the upper frame. The lower frame is in contact with the fixed base up and down, and each column is movably sleeved with a movable support.

[0014] Furthermore, sliding rods are arranged on the four sides of the lower frame and the four sides of the upper frame in a movable and adjustable manner towards the hoist tower of the concrete placing boom, and bolts for locking the sliding rods are provided.

[0018] Furthermore, a card slot for splicing the second platform plate is opened on the first platform plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] First, the present invention can be hoisted to each floor for operation by a tower crane together with the concrete placing boom, without separately erecting an operating platform and an operating frame for each floor, and is controlled to be deployed and retracted by one key, which is convenient for construction and transfer, and greatly saves time, energy, manpower and material resources.

DETAILED DESCRIPTION OF THE INVENTION

[0030] The following describes the specific embodiments of the present invention with reference to the accompanying drawings. To fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0031] In the orientation description of the present invention, the directly above of the boom of the concrete placing boom is regarded as the upper end, and the directions mentioned in the present invention, such as "up", "down", "front", "rear", "left", "right", "top", "bottom", etc., are only for reference to the directions in the accompanying drawings. Therefore, the directions used are for explaining and understanding the present invention, rather than for limiting the present invention.

[0032] As Figure 1 、 Figure 2As shown in the figure, an automatic telescopic supporting tool-type operating platform for an elevator shaft placing boom mainly includes a placing boom mast, a supporting structure, a movable supporting structure, and a platform plate structure. In the present invention, with the supporting structure sleeved on the placing boom mast as the base, a safe, efficient, and simple-operation platform is formed in the elevator shaft through the cooperation of the movable supporting structure and the platform plate structure.

[0033] As Figure 1 and Figure 2 shown in the figure, specifically, the supporting structure includes an outer frame and a fixed base 1. The outer frame is sleeved on the outside of the placing boom mast and can move freely up and down, so that the outer frame can be lifted by the tower crane to each floor without being dismantled. In addition, the fixed base 1 abuts against the bottom of the outer frame to play a supporting role, and it can also be freely installed and disassembled on the placing boom mast to move with the outer frame. Therefore, in the force-bearing support sequence, it is the fixed base 1 that first supports the outer frame, and then the outer frame supports the overall structure, transmitting its own weight and load to the fixed base 1, and finally to the placing boom mast, so that the entire outer frame can be firmly installed on the placing boom mast.

[0034] As Figure 1 、 Figure 2 shown in the figure, the movable supporting structure is arranged inside the outer frame and can move up and down, and is also equipped with a first driving member 11 for moving the movable supporting structure. Specifically, the first driving member 11 is a first electric telescopic rod, and both ends of the first electric telescopic rod are fixedly connected to the outer frame and the movable supporting structure respectively. More specifically, the movable supporting structure includes a movable support 5 and a cross bar 6. Four movable supports 5 are distributed in the four corner directions and are connected to the outer frame so as to be movable up and down. The cross bar 6 is fixedly connected between adjacent movable supports 5 by welding to form a side surface of the movable supporting structure, and is fixedly connected to the end of the first electric telescopic rod different from the outer frame.

[0035] As Figure 1 、 Figure 2 shown in the figure, the platform plate structure includes a number of first platform plates 9 and second platform plates 10. Among them, the first platform plates 9 are distributed around the outer frame and surround the outer frame in a circular manner. At the same time, one end of the first platform plate 9 is pivotally connected to the outer frame so as to be movable up and down, and a number of support rods 7 are hinged between the other end and the movable supporting structure. Specifically, three support rods 7 are arranged on each side surface of the movable supporting structure, and the three support rods 7 are respectively connected to the centers of the movable support 5 and the cross bar 6.

[0036] As Figure 1 、 Figure 2As shown in the figure, in addition, the second platform plate 10 is hinged to one side of the first platform plate 9 so as to be rotatable up and down. Specifically, the first platform plate 9 and the second platform plate 10 are connected by a shutter, and a supporting bracket 8 for supporting the second platform plate 10 is horizontally telescopically arranged between several struts 7 adjacent to the other first platform plate 9, and a second driving member 12 for telescoping the supporting bracket 8 is provided, so that the second platform plate 10 can be spliced with the other adjacent first platform plate 9 after being turned over.

[0037] As Figures 1 - 3 shown, in a specific embodiment, the telescopic movement of the first electric telescopic rod drives the cross bar 6 to move up and down within the outer frame. When the cross bar 6 moves, one end of the strut 7 connected thereto can be driven to move together, so as to switch the first platform plate 9 between the unfolded state and the retracted state. Specifically, when the first electric rod extends downward, it pushes the cross bar 6 to move downward. The cross bar 6 drives one end of the strut 7 connected thereto to move, and the other end of the strut 7 gradually approaches the direction of the cloth machine derrick, thereby driving the movable end of the first platform plate 9 to turn in the direction close to the cloth machine derrick. When the first electric telescopic rod extends to the lowest position, the strut 7 is parallel to the outer frame, and the movable support 5 is located at the bottom of the outer frame. The included angle formed by the first platform plate 9 and the outer frame is about 7 degrees. At this time, the first platform plate 9 is in the retracted state. On the contrary, when the first electric telescopic rod shortens, the cross bar 6 is lifted upward. While the strut 7 moves upward with the cross bar 6, it also pushes the first platform plate 9 outward. When the first electric telescopic rod shortens to the highest position, the included angle formed by the strut 7 and the outer frame is about 45 degrees, and the first platform plate 9 is perpendicular to the outer frame and parallel to the ground plane. At this time, the first platform plate 9 is in the unfolded state.

[0038] Considering that the operating platform will operate in elevator hoistways with different sizes, the sizes of the first platform plate 9 and the second platform plate 10 can be adaptively designed and replaced according to the sizes of different elevator hoistways, so as to achieve full-closed coverage in different elevator hoistways, which can not only ensure the safety of operators but also prevent parts from falling.

[0039] As Figure 1 shown, the outer frame includes a lower frame 2, an upper frame 3 and columns 4, all of which are located above the fixed base 1. Four columns 4 are fixedly arranged between the lower frame 2 and the upper frame 3. The lower frame 2 is in abutment with the fixed base 1 up and down, and a movable support 5 is movably sleeved on each column 4.

[0040] As Figure 1 、 Figure 4As shown, in a specific embodiment, the fixed base 1 is fixedly connected to the square steel of the concrete placing machine frame by bolts, and the upper end of the fixed base 1 and the lower end of the lower frame 2 are connected by a mortise and tenon structure. The mortise and tenon structure is a concave-convex connection method adopted by two components. The protruding part is called the tenon, and the recessed part is called the mortise. The tenon and the mortise are engaged to play a connecting role, which can not only effectively limit the twisting of the component in all directions, but also can withstand huge pressure as a whole after being combined and supported by each other, so that the lower frame 2 can be more stably connected to the fixed base 1, and can ensure that the entire outer frame is more securely fixed at the designed position of the concrete placing machine frame.

[0041] like Figure 1 As shown, the four sides of the lower frame 2 and the four sides of the upper frame 3 are all movably and adjustably provided with sliding rods 16 toward the derrick of the concrete placing machine, and are equipped with bolts for locking the sliding rods 16. The sliding rods 16 are controlled to slide inward or outward by turning the bolts clockwise or counterclockwise. In a specific embodiment, when the lower frame 2 is abutted against the fixed base 1, the bolts are tightened clockwise to push the sliding rods 16 inward. When the bolts are locked, the sliding rods 16 are tightly attached to the derrick of the concrete placing machine, further ensuring that the entire outer frame will not shake during operation. In order to facilitate the entire outer frame to be directly mounted on the derrick of the concrete placing machine during installation, the inner side dimensions of the upper frame 3 and the lower frame 2 are 50 mm longer than the outer side dimensions of the derrick of the concrete placing machine.

[0042] like Figure 5 As shown, a card interface 18 is provided on the movable support 5, and a spring buckle 17 that is engaged with the card interface 18 is movably provided on the column 4. In a specific embodiment, a mounting groove is provided on the column 4, and the lower end of the spring buckle 17 is rotatably hinged to the inside of the mounting groove, and the inside of the mounting groove is equipped with a third driving member for rotating the spring buckle 17. The third driving member includes but is not limited to a third electric telescopic rod. When the first electric telescopic rod is fully retracted, the movable support 5 is just stuck at the spring buckle 17, so that the movable support 5 is fixed on the column 4, thereby sharing the force borne by the first electric telescopic rod. At this time, the first platform plate 9 is in the expanded state. When the first platform plate 9 is to be switched to the retracted state, the spring buckle 17 can be controlled to retract and disengage from the card interface 18, and the movable support 5 can slide freely on the column 4.

[0043] like Figure 1 , Figure 6As shown, the second driving member 12 is a second electric telescopic rod, and the outer support 8 includes a support rod 13 and a support plate 14 fixedly connected to each other, and the support rod 13 is fixedly connected to the telescopic end of the second electric telescopic rod. A slot 19 for splicing the second platform plate 10 is provided on the first platform plate 9, and the slot 19 is formed by hot pressing. When the second platform plate 10 is unfolded, one end of it can be placed on the slot 19 of another adjacent first platform plate 9, and the other end can be placed on the support plate 14, so that both ends of the second platform plate 10 can be supported, ensuring that the second platform plate 10 remains spliced with the first platform plate 9.

[0044] Considering that manually building an operating platform is not only time-consuming and labor-intensive, but also poses a safety hazard, the entire operating platform adopts an automated design and is controlled by an electric system. The electric system includes a control switch 15, a power plug 20 and an internal circuit, wherein the control switch 15 is electrically connected to the first electric telescopic rod, the second electric telescopic rod and the third electric telescopic rod through the internal circuit, and the control switch 15 can be controlled by remote control.

[0045] In order to make the entire operating platform more stable and reliable during use, and have better load-bearing capacity and wear resistance, the columns 4 and the crossbars 6 are made of square steel, the support rods 7 are made of round steel, the first platform plate 9, the second platform plate 10 and the support plate 14 are all made of steel plates, wherein square steel is square solid steel, round steel is round solid steel, and steel plates are plate-shaped steel. Steel is a material of various shapes, sizes and properties required by steel ingots and steel billets through pressure processing. It not only has good tensile strength and hardness, but also has good impact toughness and weldability. It can be heat treated during processing, thereby enhancing the durability of the entire operating platform.

[0046] like Figures 1 - 6 As shown, in a specific embodiment, the use of the operating platform can be divided into three stages:

[0047] In the first stage, when installing the entire operating platform on the derrick of the concrete placing machine, first fix the four fixed bases 1 on the square steel welded to the derrick of the concrete placing machine by bolts, then sleeve the entire outer frame body on the derrick of the concrete placing machine, and make the tenons on the fixed bases 1 fit into the mortises on the lower frame 2, and finally tighten the bolts on the upper frame 3 and the lower frame 2, so that the four sliding bars 16 on the top of the outer frame and the four sliding bars 16 on the bottom are tightly in contact with the derrick of the concrete placing machine. At this point, the entire operating platform in a retracted state is fixed to the designed connection position of the derrick of the concrete placing machine. After installation, the entire operating platform can be lifted to each floor with the derrick of the concrete placing machine by the assistance of a tower crane, that is, there is no need to set up an operating platform separately on each floor;

[0048] In the second stage, after the material placing machine derrick with the operating platform installed is placed in the elevator shaft and fixed, the specific position should be the next floor of the construction floor after the platform plate is unfolded, and the control switch 15 is turned on by remote control. The second electric telescopic rod first drives the tow rod and the support plate 14 to extend outward to the appropriate position, and then the first electric telescopic rod automatically begins to shrink, driving the cross bar 6 and the movable support 5 connected below to slide upward, and then pulling the support rod 7 hingedly connected to the cross bar 6 and the movable support 5 to move upward, and the first platform plate 9 hingedly connected to the other end of the support rod 7 is thrust and rotated upward. When the first electric telescopic rod is completely retracted, the first platform plate 9 is just horizontally facing upward, and the support plate 14 is also just horizontally facing upward, and the movable support 5 is stuck at the spring buckle 17 on the column 4. Then the staff stands on the first platform plate 9 and flips the second platform plate 10 laid on it to the support plate 14 and the card slot 19. At this time, the entire operating platform is unfolded and can start working;

[0049] In the third stage, when construction of the next floor is to be carried out, the staff first flips the second platform onto the first platform board 9 and leaves, then remotely turns off the control switch 15, the spring clip 17 automatically retracts and disengages from the card interface 18, and the first electric telescopic rod begins to extend, driving the hinged cross bar 6 and the movable support 5 below to slide downward, thereby pulling the cross bar 6 and the support rod 7 hingedly connected to the movable support 5 to move downward, and the first platform board 9 hingedly connected to the other end of the support rod 7 is subjected to the tension and rotates downward. When the first electric telescopic rod is fully retracted, the support rod 7 is parallel to the column 4, the movable support 5 is in contact with the lower frame 2, and the angle formed by the first platform board 9 and the column 4 is about 7 degrees. Subsequently, the second electric telescopic rod drives the tow rod and the support plate 14 to retract inward to a suitable position. At this point, the operating platform has been retracted and can be lifted to other floors together with the derrick of the placing machine to continue operations.

[0050] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
