Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a rapidly assembled prefabricated mobile operating platform. Background Technology

[0002] As we all know, with the improvement of urbanization in my country, the construction industry has developed rapidly. Construction refers to the production activities in the implementation phase of engineering construction. It is the process of building various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at a designated location. It includes foundation construction, main structure construction, roof construction, decoration construction, etc. The place where construction work is carried out is called "construction site" or "construction site". To facilitate workers to carry out construction at heights, mobile operating platforms or scaffolding are usually used for auxiliary work. However, the existing mobile operating platforms still have some shortcomings.

[0003] However, existing rapid assembly mobile operation platforms still have certain problems in use:

[0004] A novel mobile operating platform, such as the one disclosed in Chinese Patent Publication No. CN205476386U, includes a base and a platform separated vertically, with a support frame connecting the base and the platform. The base is equipped with casters, and the platform includes an overlapping platform and a protruding platform. The projection of the overlapping platform onto the horizontal plane coincides with the projection of the base onto the horizontal plane, while the projection of the protruding platform onto the horizontal plane does not overlap with the projection of the base onto the horizontal plane. A counterweight platform is also provided on the base. However, existing mobile operating platforms still have some problems in use.

[0005] 1. Although the existing mobile operating platform adopts a stair-style inclined structure design, which makes it more convenient for personnel to go up and down, it is an integral structure design that cannot be disassembled, and its volume is relatively large, making it difficult to move and transport. At the same time, it will occupy a large space when stored.

[0006] 2. Due to its large size and weight, this mobile operating platform is difficult to move to the construction area if there are unpaved roads. Manual transport is impractical, which undoubtedly increases the difficulty of construction and makes it cumbersome and impractical. Furthermore, the structure does not have a positioning mechanism and relies on rollers to contact the ground. If it is hit during use, it will shift its position, which will not only affect the construction but also pose a safety hazard.

[0007] To address the aforementioned issues, an innovative design was developed based on the existing rapid assembly mobile operation platform. Summary of the Invention

[0008] The purpose of this invention is to provide a rapidly assembled mobile operating platform to solve the problems mentioned in the background art, such as the inability to disassemble and assemble, resulting in a large overall size, inconvenience in transportation and use, and difficulty in moving the platform when traversing unpaved roads due to the inability to disassemble and assemble.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a rapidly assembled prefabricated mobile operating platform, comprising a first support frame:

[0010] The first support frame has a second support frame at its rear end, and the front end of the second support frame extends into the interior of the first support frame. A telescopic rod is connected between the middle of the first support frame and the second support frame, and support legs are fixedly connected to the lower ends of both sides of the first support frame and the second support frame.

[0011] The first support frame and the second support frame have support rods running through their upper ends on both sides, and a support platform is provided at the upper end of the support rod. Positioning blocks are fixedly installed at the four corners of the lower end of the support platform. A ladder is provided at the lower left end of the support platform, and both ends of the ladder are bolted to the support rod.

[0012] The support rod is bolted to a connecting seat, and the inner end of the connecting seat is connected to a first connecting rod, and the end of the first connecting rod is connected to an auxiliary positioning seat.

[0013] Preferably, positioning plates are fixedly installed at both ends of the inner side of the first support frame and the second support frame, and an adjusting bolt passes through the middle of the positioning plate. A universal roller is provided at the lower end of the positioning plate. The adjusting bolt is threadedly connected to the positioning plate, and the bottom end of the adjusting bolt is connected to the universal roller bearing.

[0014] Using the above technical solution, the adjusting bolt and the universal roller are fixed by setting the positioning plate, and the height of the universal roller can be adjusted by rotating the adjusting bolt. When it is necessary to move the mobile operating platform, the universal roller can be adjusted downward to make it contact the ground, thereby facilitating its transfer.

[0015] Preferably, a positioning sleeve is fixedly connected to the middle of the front end of the second support frame, and a first threaded rod passes through the front end of the positioning sleeve. The front end of the first threaded rod passes through the interior of the first support frame, the rear end of the first threaded rod is threadedly connected to the positioning sleeve, and a first worm is fixedly connected to the front end of the first threaded rod. The front end of the first worm passes through the exterior of the first support frame, and both the first worm and the first threaded rod are connected to the bearing of the first support frame.

[0016] By adopting the above technical solution, the first worm and the positioning sleeve can be rotated to drive the first threaded rod to rotate, thereby adjusting the distance between the first support frame and the second support frame, which facilitates fixing the positions of the first and second support frames during use.

[0017] Preferably, both the first support frame and the second support frame are provided with bidirectional threaded rods, and the bidirectional threaded rods are respectively connected to the bearings of the first support frame and the second support frame. Movable positioning rods pass through both ends of the bidirectional threaded rods, and the bidirectional threaded rods are threadedly connected to the movable positioning rods. The lower ends of the support rods pass through the interiors of the first support frame and the second support frame to form a locking structure, and the movable positioning rods pass through the lower ends of the support rods.

[0018] By adopting the above technical solution, the position of the movable positioning rod can be adjusted when the bidirectional threaded rod rotates. After the support rod passes through the first support frame and the second support frame, the position between the first and second support frames and the support rod can be reliably fixed by the movable positioning rod passing through the lower end of the support rod.

[0019] Preferably, a movable rod extends through the rear end of the first threaded rod, and the movable rod has a square structure design. The movable rod is slidably connected to the first threaded rod. A second worm is fixedly connected to the rear end of the movable rod, and the second worm extends into the interior of the second support frame. The second worm is connected to a bearing on the inner wall of the second support frame.

[0020] The bidirectional threaded rod is fixedly connected to a transmission worm gear in the middle, and the first worm and the second worm are respectively meshed with two sets of transmission worm gears.

[0021] By adopting the above technical solution, the sliding fit between the movable rod and the first threaded rod can be used to adjust the rotation of the movable rod when the first threaded rod rotates, thereby driving the second worm to rotate synchronously with the first worm. When the first and second worms rotate, they cooperate with the transmission worm wheel to provide power for the rotation of the bidirectional threaded rod.

[0022] Preferably, the first connecting rod has a rotating structure with the connecting seat and the auxiliary positioning seat at both ends, and the first connecting rod, the connecting seat and the auxiliary positioning seat are symmetrically distributed at the upper and lower ends of the support rod. The auxiliary positioning seat has positioning bolts threaded on both sides, and the positioning bolts penetrate into the first connecting rod and are threaded to the first connecting rod.

[0023] By adopting the above technical solution, the stability of the support rod after installation can be improved through the cooperation between the two sets of first connecting rods and the auxiliary positioning seat. At the same time, it is also convenient for the two sets of support rods to be folded and reduced in size after disassembly. The positioning bolts can fix the auxiliary positioning seat and the first connecting rod, restrict the rotation of the first connecting rod, and improve the reliability of the fixation.

[0024] Preferably, the two support rods on both sides are provided with mounting grooves on opposite sides, and the mounting grooves are connected to the shafts of the second connecting rods. The ends of the two sets of second connecting rods are respectively connected to second threaded rods. The two sets of second threaded rods are arranged with the same thread direction, and the front end of the second threaded rod is provided with an internal threaded sleeve, which is threadedly connected to the two sets of second threaded rods respectively.

[0025] Using the above technical solution, the installation groove facilitates the storage of the second connecting rod. After the support rod is installed vertically, it can be connected through the cooperation between the second threaded rod and the internal threaded sleeve in the middle of the two sets of second connecting rods. Rotating the internal threaded sleeve synchronously connects with the second threaded rod, thereby fixing the position of the two sets of second connecting rods.

[0026] Preferably, the upper end of the support rod has two sets of limiting plates, and the upper end of the limiting plates extends into the interior of the positioning block. The limiting plates are designed in an "L" shape, and the limiting plates and the inner wall of the positioning block form a locking structure. A limiting rod passes through the middle of the limiting plate, and both ends of the limiting rod are fixedly connected to the inner wall of the support rod. A return spring passes through both ends of the limiting rod, and both ends of the return spring are fixedly connected to the inner wall of the support rod and the limiting plate, respectively.

[0027] By adopting the above technical solution, the upper support platform can be easily fixed by the interlocking cooperation between the limiting plate and the positioning block, ensuring the stability of its installation. The limiting rod can improve the stability of the limiting plate's movement, and with the help of the return spring, it can be reset to the middle of the support rod when the limiting plate's movement is unrestricted.

[0028] Preferably, a transmission rack is slidably connected to the upper end of the mounting groove, and the upper end of the transmission rack has an "L" shaped structure design. A limit block is fixedly connected to the upper end of the transmission rack. The upper end of the limit block has a triangular structure design, and the two sides of the upper end of the limit block contact the inner side of the limit plate. The lower ends of the two sets of limit plates on opposite sides have an inclined surface design. A transmission gear is meshed with the lower end of the transmission rack, and the transmission gear is fixedly connected to the end of the second connecting rod.

[0029] By adopting the above technical solution, through the cooperation between the transmission gear and the transmission rack, the transmission gear can drive the transmission rack and the limiting block to move synchronously when the second connecting rod is rotated. Then, the limiting block pushes the two sets of limiting plates to move in opposite directions and engage with the positioning block, thereby fixing the position of the support platform.

[0030] Compared with the prior art, the beneficial effects of the present invention are: the quick-assembly prefabricated mobile operating platform has improved ease of use and practicality due to its prefabricated structure design. The mobile operating platform is small in size and light in weight after disassembly, making it easy to handle manually. It can adapt to complex unpaved construction sites and occupies little space when disassembled and stored. The mobile operating platform adopts a quick connection and fixing method, which can be quickly and conveniently assembled during use, improving work efficiency.

[0031] 1. The mobile operating platform consists of three parts: upper, middle and lower. When assembling the lower first and second support frames, the middle support rod can be fixed and positioned simultaneously. When reinforcing the middle support rod, the upper support platform can be fixed simultaneously, which greatly improves assembly efficiency and ease of operation. Attached Figure Description

[0044] Please see Figure 1-10 This invention provides a technical solution: a rapidly assembled mobile operating platform, comprising a first support frame 1, a second support frame 2 disposed at the rear end of the first support frame 1, and the front end of the second support frame 2 penetrating into the interior of the first support frame 1; a telescopic rod 3 is connected between the middle of the first support frame 1 and the second support frame 2; and support legs 4 are fixedly connected to the lower ends of both sides of the first support frame 1 and the second support frame 2; positioning plates 5 are fixedly installed at both ends of the inner sides of the first support frame 1 and the second support frame 2; an adjusting bolt 6 penetrates the middle of the positioning plate 5; and a universal roller 7 is disposed at the lower end of the positioning plate 5. Bolt 6 is threadedly connected to positioning plate 5, and the bottom end of adjusting bolt 6 is connected to the bearing of universal roller 7. The first support frame 1 and the second support frame 2 are supported by multiple sets of support legs 4. The positioning plate 5 connected inside the first support frame 1 and the second support frame 2 can install adjusting bolt 6 and universal roller 7. By rotating adjusting bolt 6, the height of universal roller 7 can be increased, which makes it easier to adjust the universal roller 7 to contact the ground when the operating platform needs to be moved, thus improving the convenience of transfer operation. At the same time, the height of universal roller 7 can be increased during construction to improve the stability of the operating platform.

[0045] Support rods 8 extend through the upper ends of both sides of the first support frame 1 and the second support frame 2. A positioning sleeve 21 is fixedly connected to the middle of the front end of the second support frame 2, and a first threaded rod 19 extends through the front end of the positioning sleeve 21, penetrating into the first support frame 1. The rear end of the first threaded rod 19 is threadedly connected to the positioning sleeve 21, and a first worm gear 20 is fixedly connected to the front end of the first threaded rod 19, penetrating the exterior of the first support frame 1. Both the first worm gear 20 and the first threaded rod 19 are connected to the bearings of the first support frame 1.

The second worm gear 23 is connected to a bearing on the inner wall of the second support frame 2. A transmission worm wheel 18 is fixedly connected to the middle of the bidirectional threaded rod 16. The first worm gear 20 and the second worm gear 23 are respectively meshed with two sets of transmission worm wheels 18. During assembly of the mobile operating platform, the lower ends of multiple sets of support rods 8 are first engaged with the first support frame 1 and the second support frame 2. Then, by rotating the second worm gear 23, the first threaded rod 19 is rotated. Through its cooperation with the positioning sleeve 21, the first support rod 19 is adjusted. The distance between the support frame 1 and the second support frame 2 is such that, while the first threaded rod 19 rotates, the movable rod 22, which is slidably engaged with its rear end, drives the second worm gear 23 to rotate synchronously. The first worm gear 20 and the second worm gear 23 drive the two sets of transmission worm wheels 18 and the bidirectional threaded rod 16 to rotate synchronously, and drive the movable positioning rod 17 to move outward and pass through the lower end of the support rod 8, thereby fixing the position between the support rod 8 and the first support frame 1 and the second support frame 2. The support rod 8 is fixed while the first support frame 1 and the second support frame 2 are unfolded. The operation is simple and convenient, and the efficiency of assembly and disassembly is improved.

[0046] A connecting seat 12 is bolted to the inner side of the support rod 8, and a first connecting rod 13 is connected to the inner end of the connecting seat 12. An auxiliary positioning seat 14 is connected to the end of the first connecting rod 13.

The first connecting rod 13, the connecting seat 12, and the auxiliary positioning seat 14 are symmetrically distributed at the upper and lower ends of the support rod 8. Positioning bolts 15 are threaded to both sides of the auxiliary positioning seat 14, and the positioning bolts 15 penetrate into the interior of the first connecting rod 13. The positioning bolts 15 are threaded to the first connecting rod 13. The two sets of first connecting rods 13 can improve the strength between the two sets of support rods 8 and the overall installation stability.

A transmission rack 31 is slidably connected to the upper end of the mounting groove 24, and the upper end of the transmission rack 31 is L-shaped. A limiting block 32 is fixedly connected to the upper end of the transmission rack 31. The upper end of the limiting block 32 has a triangular structure design, and both sides of the upper end of the limiting block 32 contact the inner side of the limiting plate 28.

A transmission gear 33 is meshed with the lower end of the transmission rack 31, and the transmission gear 33 is fixedly connected to the end of the second connecting rod 25. The mounting groove 24 opened on the side of the support rod 8 facilitates the storage of the second connecting rod 25. The setting of the second connecting rod 25 can further improve the stability and structural strength of the support rod 8 after installation. It can be threaded by two sets of second threaded rods 26 and internal threaded sleeves 27. The two sets of second connecting rods 25 are connected together. At the same time, the rotation of the second connecting rods 25 can drive the transmission gear 33 to rotate.
