Description

Technical Field

[0001] The utility model relates to the technical field of elevator frames, in particular to a cement column supporting frame for installing an elevator. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rigid rails that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. There are also step-type elevators, where the treads are mounted on crawlers and run continuously, commonly known as escalators or moving walkways. A fixed lifting device that serves specified floors. A vertical lift has a car that runs between at least two rigid rails that are perpendicular or inclined at an angle of less than 15°. The size and structure of the car facilitate passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation tools in buildings regardless of their driving mode. According to speed, it can be divided into low-speed elevators (below 4 m / s), fast elevators (4 to 12 m / s) and high-speed elevators (above 12 m / s). The elevator support frame is a structure installed in the elevator shaft to support and fix the elevator rails, guide rails and related components. Its main function is to provide a stable support to ensure the safety and stability of the elevator during operation. The support frame is usually made of steel and concrete columns, with sufficient strength and rigidity to withstand the load and vibration generated during the operation of the elevator. Its design takes into account the weight, operating speed and various dynamic loads of the elevator to ensure the stability and reliability of the entire system.

[0003] The prior art (publication number: CN 215564708 U) discloses a cement column support frame for installing an elevator, which relates to the field of elevator installation technology, and includes columns vertically arranged at the four corners of the elevator shaft, and a crossbeam is arranged between two of the columns located on the same side of the elevator shaft, and the columns include a plurality of cement columns spliced ​​end to end, and a connecting piece for fixing the cement columns is arranged at the splicing position of the two cement columns; guide rails are vertically arranged on the crossbeams on two opposite sides of the cement column support frame, and a construction platform is vertically slidably connected to the guide rails, and a driving component for driving the construction platform to rise and fall is arranged on the construction platform.

[0004] Although the above patent has the effect of improving the inconvenience caused by the construction site to the installation of elevators and improving the construction efficiency, it has the following disadvantages. When in use, the size of the support frame cannot be adjusted, which may result in the inability to install suitable elevator equipment under specific shaft size or structural restrictions, limiting the selection and application scope of the elevator system. Further improvement is needed. For this reason, we propose a cement column support frame for installing elevators. Utility Model Content

[0024] like Figure 1-Figure 4 As shown, a cement column support frame for installing an elevator includes a base 1, and slide rails 2 are installed at the front and rear upper ends of the base 1. A rectangular groove 6 is opened at the upper right part of the base 1, and an adjusting component 5 is installed at the middle of the upper end of the base 1. Two sliders 3 are movably sleeved on the outer surfaces of the two slide rails 2, and cement columns 7 are installed at the upper ends of the four sliders 3. A rotating component 14 is arranged in the rectangular groove 6, and the rotating component 14 is fixedly connected to the adjusting component 5.

[0025] The distance between the cement columns 7 can be adjusted by the adjusting component 5, and the specific structure is as follows: the adjusting component 5 includes a bearing seat 51, two bearing seats 51 are provided and are distributed on the left and right, the two bearing seats 51 are installed in the middle of the upper end of the base 1, and a rotatable positive and negative threaded rod 52 is commonly provided between the two bearing seats 51, and the outer surface of the positive and negative threaded rod 52 is threadedly sleeved with two left and right symmetrically distributed moving rods 53, and the front and rear ends of the two moving rods 53 are fixedly connected with four sliders 3 respectively. When in use, the positive and negative threaded rods 52 are driven to rotate, and the positive and negative threaded rods 52 simultaneously drive the two moving rods 53 to move away from each other, and the two moving rods 53 respectively drive the left and right cement columns 7 to move away from each other. On the contrary, the positive and negative threaded rods 52 are rotated in the opposite direction, and the two cement columns 7 are moved away from each other, so that the size of the frame can be adjusted, which is convenient for adapting to the selection and application range of different elevator systems.

[0026] Since the cement column has a certain weight, in order to drive the forward and reverse threaded rods 52 to rotate with less effort, the adjusting component 5 is adjusted by the rotating component 14. The rotating component 14 includes a vertical plate 141. Two vertical plates 141 are arranged and distributed front and back. A rotatable worm 142 is installed between the two vertical plates 141. The outer surface of the worm 142 is meshed and connected with a worm wheel 143. The internal fixing kit of the worm wheel 143 has a connecting shaft 144. When in use, the worm 142 is driven to rotate, and the worm 142 drives the worm wheel 143 to rotate. The worm wheel 143 then drives the forward and reverse threaded rods 52 to rotate through the connecting shaft 144. Through the mutual meshing of the worm wheel 143 and the worm 142, the input rotational motion is converted into the output rotational motion, and a large speed ratio can be achieved, thereby achieving a labor-saving effect. The labor-saving structure can drive movement or perform work through mechanical or other means, reducing manpower input, improving efficiency, and reducing labor intensity. The worm 142 can be driven by a motor or a knob.

[0027] In order to drive the forward and reverse threaded rod 52 to rotate, the rear end of the connecting shaft 144 movably passes through the right bearing seat 51 and is fixedly connected to the right end of the forward and reverse threaded rod 52 .

[0028] The four corners of the upper end of the slider 3 are each provided with a first fixing hole 4 . After the adjustment is completed, bolts are inserted into the first fixing holes 4 to fix the slider 3 .

[0029] In order to improve the stability between the cement columns 7, a connecting rod 8 is installed between the front and rear cement columns 7, a cross bar 15 is installed at the ends of the left and right cement columns 7 that are close to each other, a connecting seat 9 is installed at the upper end of the cement column 7, and a hollow rod 11 is movably sleeved on the outer surfaces of the left and right cross bars 15. A plurality of screw holes 13 distributed in a linear array are opened at the front end of the cross bar 15, and two screws 12 are arranged at the front end of the hollow rod 11. The screws 12 extend into the screw holes 13, and second fixing holes 10 are installed at the four corners of the upper end of the connecting seat 9. When the distance between the cement columns 7 is adjusted, the screw 12 is rotated to screw it into the screw hole 13 to fix the length of the cross bar 15.
