Description

Technical Field

[0001] The invention relates to a gradient arc angle V-shaped column foundation stair installation auxiliary mechanism and a use method thereof, belonging to the technical field of building construction. Background Art

[0002] There are many curves and curved surfaces in nature. In the process of human beings getting along with nature, curves have become an ideology, which constantly penetrates and influences people's perception of beauty. In space decoration design, streamlined curve elements can break the dullness and boredom of straight lines, add agility to the space, and give the space variability. Curves are different from the modernity and stability of straight lines. Curves have a soft, graceful and jumping feeling, which makes people feel smooth and reminds people of natural rivers, terrain, etc. At present, in subway decoration design, curves and curved surface elements are gradually becoming the mainstream, aiming to create a comfortable atmosphere for passengers in the claustrophobic underground space, but this brings great challenges to subway construction.

[0003] Especially in the installation and decoration construction of subway escalators, most of them are deep and long escalators that span multiple basements. In order to pursue the spatial curve effect, a certain subway station used V-shaped column steel structure to support the deep and long escalator columns during design.

[0004] In the prior art, in order to facilitate hoisting, a long escalator is usually hoisted and installed in sections. In order to facilitate the alignment between different escalator sections, a crane is usually used in conjunction with manual rope pulling to adjust the position and angle of the escalator section in the air. The above method has the following technical problems: 1. Manually pulling the rope requires manual entry into the lifting operation site, which poses certain safety hazards, and the adjustment requires a lot of manpower. In addition, the adjustment accuracy is not high and requires repeated adjustments, which leads to low lifting efficiency.

[0005] 2. Due to the design of the V-shaped column, the V-shaped column must be installed first, and then the escalator. The escalator is hoisted in sections, so it is necessary to consider the alignment between different escalator sections and the coordination and installation of different escalator sections and the V-shaped column, which increases the difficulty of hoisting the escalator sections.

[0006] 3. Before the escalator is fully installed, the stress conditions on both sides of the V-shaped column are uneven, and the V-shaped column is prone to deformation, affecting the overall stress conditions in the later stage. Summary of the invention

[0009] Preferably, the upper and lower parts of the V-shaped column are connected via a rotating mechanism, which includes a rotating disk rotatably connected between the upper and lower parts of the V-shaped column, and the rotating disk is driven by a motor fixed to the lower part of the V-shaped column.

[0010] Preferably, the upper end of the slide groove is V-shaped.

[0011] Preferably, a limiting block is slidably connected to the interior of the lower end of the slide slot, the limiting block can slide relative to the slide slot, and the limiting block is limited in the slide slot by bolts.

[0012] Preferably, it further comprises an alignment mechanism, which comprises a laser transmitter and a receiver, and the laser transmitter and the laser receiver are respectively and correspondingly detachably connected to the ends of two adjacent escalator sections that are close to each other.

[0013] Preferably, the laser transmitter and the laser receiver are electrically connected to the motor.

[0014] Preferably, a telescopic rod is detachably connected between the two ends of the upper portion of the V-shaped column.

Compared with the prior art, the present invention provides a guide mechanism and a limit block at the connection between the V-shaped column and the escalator, a rotating disk is provided on the V-shaped column, and an alignment mechanism is provided between adjacent escalators. The V-shaped column is used to realize rapid alignment of the stair sections without repeated adjustments, and the hoisting accuracy and efficiency are high. The problem of high hoisting difficulty caused by the cooperation between the V-shaped column and the escalator in the prior art is overcome.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment 1: Gradual arc angle V-shaped column foundation staircase installation auxiliary mechanism, such as Figure 1 As shown, it includes a guide mechanism fixed on the upper end of the V-shaped column, the guide mechanism includes a strip-shaped slide groove 25 consistent with the inclination angle of the escalator, the lower end of the slide groove 25 is closed, and the upper end of the slide groove 25 is provided with a V-shaped portion 27. The escalator is divided into three sections from bottom to top, which are named the first section 11, the second section 12 and the third section 13 respectively. The length of the slide groove 25 extends from the upper part of the first section 11 to the lower part of the third section 13; the lower ends of the second section 12 and the third section 13 are respectively provided with a strip-shaped first slider 14 and a second slider 15 that cooperate with the slide groove 25. The first slider 14 and the second slider 15 are inserted into the slide groove 25 from the V-shaped portion 27 at the upper end of the slide groove 25 and can slide along the slide groove 25. The first slider 14 and the second slider 15 are both limited inside the slide groove 25 by bolt connection.

[0022] like Figure 1 As shown, a bar-shaped limit block 26 is slidably connected to the lower end of the slide slot 25, and the limit block 26 can slide relative to the slide slot 25. The limit block 26 is limited in the slide slot 25 by bolts. The limit block 26 is used to limit the position of the first slider 14 when it slides downward.

[0023] like Figure 1 As shown, a rotating disk 23 is fixed to the lower end of the upper part of the V-shaped column, and the rotating disk 23 and the lower part 20 of the V-shaped column are rotatably connected. The rotating disk 23 is driven by a motor 24 fixed on the lower part of the V-shaped column. After the angle between the upper and lower parts of the V-shaped column is adjusted, it is limited by bolt connection.

[0024] In this embodiment, an alignment mechanism is also included, such as Figure 1As shown, the alignment mechanism includes a laser emitter 16 and a laser receiver 17, which are respectively detachably connected to the ends of two adjacent escalator sections that are close to each other, and the laser emitter 16 and the laser receiver 17 are electrically connected to the motor 24. When the motor 24 is turned on, the motor 24 drives the rotating disk 23 to drive the upper end of the V-shaped column to rotate. When the laser receiver 17 receives the laser emitted by the laser emitter 16, the controller controls the motor 24 to stop rotating, thereby realizing the automatic alignment of the two adjacent escalator sections.

[0025] In this embodiment, Figure 1 As shown, a telescopic rod is detachably connected between the two ends of the upper part of the V-shaped column. The length of the telescopic rod and the position of the left and right ends are adjusted according to the change of the force on the V-shaped column during the lifting process, so as to adjust the force condition of the V-shaped column and avoid deformation of the V-shaped column.

[0026] Method of using the installation auxiliary mechanism for the gradient arc angle V-shaped column foundation stairs: after installing the first stair section 11 and the V-shaped column according to the design requirements, the laser transmitter 16 and the laser receiver 17 are detachably connected to the upper end of the first stair section 11 and the lower end of the second stair section 12 respectively. During the process of hoisting the second stair section 12, first adjust the limit block 26 so that the second stair section 12 can only slide downward to a distance of 15 cm from the first stair section 11, leaving a gap for adjusting the angle of the second stair section 12, and then under the action of gravity, the slider at the lower end of the second stair section 12 slides from the V-shaped part at the upper end of the slide groove 25 into the slide groove 25 until it contacts the limit block 26, and then turn on the motor 24, the motor 24 drives the rotating disk 23 to drive the upper end of the V-shaped column to rotate, and when the laser receiver 17 receives the laser emitted by the laser transmitter 16 At this time, the controller controls the motor 24 to stop rotating, so as to realize automatic alignment of the first stair section 11 and the second stair section 12, and fix the upper and lower parts of the V-shaped column with bolts; then the limit block 26 is slid to the bottom of the slide groove 25, and under the action of gravity, the slider drives the second stair section 12 to slide downward until it contacts with the first stair section 11, and then the first stair section 11 and the second stair section 12 are rigidly connected and limited by bolts; similarly, in the process of hoisting the third stair section 13, under the action of gravity, the slider at the lower end of the third stair section 13 slides from the V-shaped part at the upper end of the slide groove 25 into the slide groove 25 until it contacts with the second stair section 12, and then the second stair section 12 and the third stair section 13 are rigidly connected and limited by bolts; in this process, the third stair section 13 and the second stair section 12 are automatically aligned, and there is no need to adjust the angle of the third stair section 13.

[0027] If the second stair section 12 needs to be divided into more than two stair sections, when the stair section at the upper left end is hoisted, only the upper left end of the V-shaped column is stressed, which may easily cause deformation of the upper left end of the V-shaped column. Therefore, during the process of hoisting the stair section at the left end, the upper right end of the V-shaped column is used to apply a rightward pulling force to the upper left end of the V-shaped column through the telescopic rod to avoid deformation of the left side of the V-shaped column.

[0028] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
