Description

A temporary support for lifting auxiliary scaffolding Technical Field

[0001] This utility model relates to the field of scaffolding technology, specifically to an auxiliary temporary support for the lifting of attached lifting scaffolding. Background Technology

[0002] The auxiliary temporary support for the attached lifting scaffold is an important component of the attached lifting scaffold system. When the attached lifting scaffold is being lifted or lowered, the auxiliary temporary support can serve as a temporary support point to bear part or all of the load of the scaffold.

[0003] Existing temporary supports for attached lifting scaffolding have inadequate structural design in terms of guidance and limiting, failing to effectively ensure the stability of the scaffolding during lifting and preventing the dangers of deviation, swaying, or torsion. Furthermore, traditional supports rely on only a few support points to transfer loads, leading to localized stress concentrations that can easily cause deformation or failure of the support structure. Additionally, the base and support may be fixed by welding or traditional bolts, making assembly and disassembly time-consuming, labor-intensive, and requiring specialized tools, hindering rapid on-site deployment or adjustment.

[0004] Therefore, it is necessary to invent an auxiliary temporary support for the lifting of attached elevating scaffolding to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide an auxiliary temporary support for the lifting of attached elevating scaffolding, so as to solve the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a temporary support for lifting scaffolding, comprising a base, a support seat above the base, a screw rod vertically fixed at the top center of the support seat, a nut threaded onto the screw rod, and a support mechanism above the support seat and surrounding the screw rod.

[0007] The supporting structure includes:

[0008] Multiple guide rods are arranged in a ring array on the support base, and the front end of each guide rod is detachably and fixedly connected to the lower end of the screw.

[0009] Multiple limiting seats are disposed on the support base, and each limiting seat has a support frame at its upper end;

[0010] A scaffold is installed above the screw, and multiple evenly distributed connecting parts are fixed to the outside of the scaffold, with each connecting part corresponding to a limiting seat.

[0011] As a preferred embodiment of this utility model, a crossbar is fixedly installed at the front end of the connecting part, a slot is opened at the front end of the support frame, and the slot engages and abuts against the lower part of the corresponding crossbar. The bottom of the support frame is located on the corresponding limiting seat, and the limiting seat has an L-shaped structure.

[0012] As a preferred embodiment of this utility model, the lower end of the limiting seat has a through hole extending horizontally, the guide rod is movably inserted into the through hole of the corresponding limiting seat, a spring is sleeved between the tail end of the guide rod and the tail end of the limiting seat, and the bottom of the limiting seat can slide on the upper surface of the support seat.

[0013] As a preferred embodiment of this utility model, the lower end of the scaffold is movably sleeved on the screw rod, the bottom of the scaffold is located on the upper surface of the nut, and a handle is fixedly installed on the outside of the nut.

[0014] As a preferred embodiment of this utility model, a locking block is fixedly installed on the upper end of the base. The locking block has a multi-faceted structure, and each face of the locking block has a horizontally opened insertion hole. The bottom of the support base has a locking groove, which is adapted to the locking block and engages with it.

[0015] As a preferred embodiment of this utility model, a plug rod is inserted horizontally through the bottom of the support base, and the plug rod is inserted into the plug hole of the card block.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides a temporary support for lifting and lowering scaffolding as shown in Figures 1-5, including a base 1, a support seat 2 above the base 1, a screw 22 vertically fixed at the top center of the support seat 2, a nut 23 threaded onto the screw 22, and a support mechanism 3 above the support seat 2 and around the screw 22.

[0028] Supporting mechanism 3 includes:

[0029] Multiple guide rods 31 are arranged in a ring array on the support base 2, and the front end of each guide rod 31 is detachably fixed to the lower end of the screw 22.

[0030] Multiple limiting seats 33 are provided on the support seat 2, and each limiting seat 33 has a support frame 35 at its upper end;

[0031] A scaffold 4 is installed above the screw 22. Multiple evenly distributed connecting parts 41 are fixed on the outside of the scaffold 4, and the connecting parts 41 correspond one-to-one with the limiting seats 33.

[0032] In this example, the circular array of guide rods 31 provides all-around guidance and support for the lifting and lowering of the scaffolding 4. Compared to the imperfections of existing support and guidance structures, this design effectively prevents the scaffolding from shifting, swaying, or twisting during lifting and lowering, ensuring its smooth lifting and lowering along a predetermined trajectory. The detachable connection facilitates operation during installation, maintenance, or replacement of parts. Simultaneously, the cooperation between the guide rods 31 and the limiting seat 33 restricts the movement direction of the limiting seat 33, further enhancing the stability of the entire support mechanism.

[0033] Furthermore, in the above technical solution, a crossbar 42 is fixedly installed at the front end of the connecting part 41, a slot is opened at the front end of the support frame 35, and the slot engages and abuts against the lower part of the corresponding crossbar 42. The bottom of the support frame 35 is located on the corresponding limiting seat 33, and the limiting seat 33 has an L-shaped structure.

[0034] In this example, the limiting seat 33 corresponds one-to-one with the connecting part 41 of the scaffold 4. The supporting frame 35 engages with the horizontal bar 42 through the slot at its front end, thus limiting the scaffold 4. The L-shaped limiting seat 33 not only provides stable support for the supporting frame 35 but also, together with the guide rod 31 and the supporting seat 2, forms a robust support system. This structural design effectively transfers the load borne by the scaffold 4 to the supporting seat 2, and then through the supporting seat 2 to the base 1 and the building structure, avoiding localized stress concentration and improving the load-bearing capacity and reliability of the support structure.

[0035] Furthermore, in the above technical solution, a through hole 34 is transversely opened at the lower end of the limiting seat 33. The guide rod 31 is movably inserted into the corresponding through hole 34 of the limiting seat 33. A spring 32 is sleeved between the tail end of the guide rod 31 and the tail end of the limiting seat 33. The bottom of the limiting seat 33 can slide on the upper surface of the support seat 2. The spring 32 allows the limiting seat 33 to buffer the impact by sliding on the upper surface of the support seat 2 and compressing the spring 32 when subjected to the impact force during the lifting and lowering of the scaffold. This buffering mechanism effectively reduces the damage of the impact force to the scaffold and the entire support structure, improves the stability and safety during the lifting and lowering of the scaffold, and also extends the service life of each component.

[0036] Furthermore, in the above technical solution, the lower end of the scaffold 4 is movably sleeved on the screw 22, and the bottom of the scaffold 4 is located on the upper surface of the nut 23. A handle 24 is fixedly installed on the outside of the nut 23. By rotating the nut 23 with the handle 24, the height of the scaffold 4 can be easily adjusted. Before the scaffold lifting operation, the position of the scaffold can be precisely adjusted according to actual needs to better adapt to different lifting conditions and load distributions. This height adjustment function helps to evenly distribute the load, avoid local stress concentration caused by unsuitable height, and also improves the stability of the scaffold during the lifting process.

[0037] Furthermore, in the above technical solution, a card block 11 is fixedly installed on the upper end of the base 1. The card block 11 has a multi-faceted structure, and each face of the card block 11 has a horizontally opened insertion hole 13. The bottom of the support base 2 has a card groove 21, which is adapted to the card block 11 and is engaged and connected.

[0038] Furthermore, in the above technical solution, a horizontally inserted rod 12 is provided through the bottom of the support base 2. The rod 12 is inserted into the insertion hole 13 of the locking block 11. The multi-faceted locking block 11 at the upper end of the base 1 is adapted to the locking groove 21 at the bottom of the support base 2. This locking connection method greatly improves the convenience of installation and disassembly compared to traditional welding or ordinary bolt fixing. No professional tools are required to quickly connect and separate the base 1 and the support base 2, facilitating rapid on-site deployment or adjustment. At the same time, the design of multiple insertion holes 13 allows the support base 2 to be adjusted according to actual needs during installation, enhancing the adaptability of the support in different scenarios.

[0039] The working process of the temporary support for lifting scaffolding provided by this utility model is as follows:

[0040] Place the base 1 in the predetermined position and stabilize it. Align the slot 21 at the bottom of the support 2 with the locking block 11 at the top of the base 1, and slowly lower it to ensure a tight fit. Then, insert the insertion rod 12 horizontally through the bottom of the support 2 and into the insertion hole 13 of the locking block 11, ensuring a secure connection between the support 2 and the base 1 to prevent displacement during subsequent operations. On the support 2, according to the requirements of a circular array distribution, fix the front ends of multiple guide rods 31 to the lower ends of screws 22 using a detachable connection. Next, install the limiting seat 33 on the support 2, allowing the guide rods 31 to be movably inserted into the through hole 34 at the lower end of the limiting seat 33, and attach springs 32 to the tail ends of the guide rods 31 and the limiting seat 33. Install the support frame 35 on the upper end of the limiting seat 33.

[0041] The lower end of the scaffold 4 is movably connected to the screw 22, so that the bottom of the scaffold 4 rests stably on the upper surface of the nut 23. The position of the scaffold 4 is adjusted so that the connecting part 41 corresponds one-to-one with the limiting seat 33. Then, the slot at the front end of the support frame 35 is engaged and abutted against the lower part of the corresponding horizontal bar 42, thus completing the connection between the scaffold and the temporary support.

[0042] According to actual construction needs, if the height of scaffolding 4 needs to be adjusted, construction workers can rotate the handle 24 on the outside of nut 23 to move nut 23 up and down on screw 22, thereby driving scaffolding 4 to rise or fall until the required height is reached. Since the length of support frame 35 in support mechanism 3 is fixed, when scaffolding 4 rises, the upper end slot of support frame 35 takes its connected crossbar 42 as the origin, and the lower end of support frame 35 slides or moves towards scaffolding 4 on the L-shaped plane of limit seat 33. The high-strength spring 32 on the corresponding guide rod 31 of support frame 35 abuts against limit seat 33 and moves towards scaffolding 4, thereby fixing the position of support frame 35. If scaffolding 4 falls, the same principle applies. The lower end of the support frame 35 slides or moves away from the scaffold 4, while the top of the support frame 35 is lowered, and the height of its bottom end remains unchanged, always located on the L-shaped plane of the limiting seat 33. Consequently, the limiting seat 33 is resisted by the lower end of the support frame 35 and moves away from the scaffold 4, compressing the high-strength spring 32. When the high-strength spring 32 is compressed to a certain position, the position of the limiting seat 33 remains unchanged, and thus the position of the support frame 35 remains unchanged, thereby achieving support for one side of the lower end of the scaffold 4.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
