DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings in order to better understand the technical solution.

[0027] The present invention provides a modular guide rail mounting bracket structure. The modular guide rail mounting bracket structure aims to design a special aluminum profile main beam, which is matched with a sheet metal structure to form a modular guide rail mounting bracket structure. Since the profile processing straightness and flatness have natural advantages over the sheet metal structure, the structure with the profile main beam as the skeleton is simple to process and manufacture, has high precision, and is assembled in the factory. The on-site installation is simpler and highly standardized. Due to the many advantages, this special modular guide rail mounting bracket structure can be designed to replace the current sheet metal structure.

[0028] Its specific structure is as follows Figure 1-5As shown in 7-8, the bracket structure includes a bottom guide bracket 1, an intermediate guide bracket 2 and a top guide bracket 3 which are arranged in sequence, wherein each of the bottom guide bracket 1 and the top guide bracket 3 is provided with one, and the intermediate guide bracket 2 is provided with n, wherein n≥0; wherein, the bottom guide bracket 1, the intermediate guide bracket 2 and the top guide bracket 3 all include a shaft rear side decorative panel 4, an aluminum profile main beam 5, a sheet metal bottom beam 6 and a sheet metal part 7, and the aluminum profile main beam 5 is integrated with a counterweight side auxiliary guide rail 8, a straight-shaped connector mounting groove 9 which passes through from top to bottom, a standard T-shaped bolt mounting groove 10 and a weight reduction hole 11, and the straight-shaped connector 12 is used in the straight-shaped connector mounting groove 9 to realize the integration of the backpack side T78 main rail 13 and the aluminum profile main beam 5. A top beam mechanism 19 is also installed at the upper end of the top guide rail bracket 3. The top beam mechanism 19 also includes a rear decorative plate 4 of the shaft. The top end of the top beam mechanism 19 is provided with a mounting hole 20 connected to the top floor slab for connecting with the expansion screws on the top of the floor slab.

[0029] The above-mentioned specially molded aluminum profile main beam 5 has better strength than the square tube structure of sheet metal welding, and has an integrated counterweight auxiliary guide rail function to reduce on-site installation man-hours. The straight connector 12 structure on the aluminum profile main beam 5 is shared with the T78 main rail connecting plate, eliminating the rail connecting plate; the design of the weight reduction hole 11 reduces production costs, and at the same time, it is calculated that the bending strength is about 200% higher than that of traditional sheet metal beams; all installation slots are designed to meet the applicability of national standard T-bolts / nuts / straight connectors; the guide rail mounting brackets are divided into three types: bottom, middle, and top. The top and middle guide rail brackets have unique lengths, and the bottom guide rail length is calculated according to different values ​​of the shaft height. The modular combination of the three guide rails can adapt to shafts of any height.

[0030] like Figure 1 , 4 -5 and 7, the sheet metal part 7 is installed at both ends of the sheet metal bottom beam 6 and is vertically arranged with the sheet metal bottom beam 6. The sheet metal bottom beam 6 is connected to the straight connector 12 by M6 countersunk screws, and a reinforcing connector 14 is also arranged between the sheet metal bottom beam 6 and the aluminum profile main beam 5. A guide rail gasket 15 is arranged at the position of the aluminum profile main beam 5 corresponding to the sheet metal bottom beam 6. A pressure guide plate connecting hole is arranged on the aluminum profile main beam 5 corresponding to the end of the guide rail gasket 15 close to the sheet metal bottom beam 6, and a T75 pressure guide plate 16 is installed and fixed in the pressure guide plate connecting hole. An L-shaped connecting bracket 17 is installed at the lower end of the aluminum profile main beam 5 of the bottom guide rail bracket 1, and an expansion bolt mounting hole is arranged on the L-shaped connecting bracket 17 for fixing to the ground. The ends of the connection places of the rear decorative panels 4 of adjacent shafts are provided with reinforcing ribs 18, and waist-shaped holes are provided on the reinforcing ribs 18. Connecting screws are provided in the waist-shaped holes to connect the reinforcing ribs 18 with the corresponding rear decorative panels 4 of the shaft, and to cover the gaps of the rear decorative panels 4 of adjacent shafts.

[0031] The aluminum profile is pre-equipped with a pressure guide plate installation hole when it leaves the factory, which is very convenient for installation. The setting of the reinforcing rib plate 18 can cover the gap between the rear side decorative plates 4 of adjacent wells, thereby increasing the overall aesthetics of the product.

[0032] In order to increase the overall installation firmness of the mounting bracket, an L-shaped connecting plate is further provided on the aluminum profile main beam 5, and the L-shaped connecting plate is connected to the rear shaft expansion screws through the connecting holes provided thereon, and an L-shaped anti-loosening bracket is provided on the reinforcing rib plate 18. Circular holes are provided at both ends of the L-shaped anti-loosening bracket. During the specific installation, first loosen the locking nut shared with the rear decorative panel, and then install the L-shaped anti-loosening bracket and connect it to the side shaft frame. This anti-loosening bracket can be fixed at any loose part of the rear decorative panel.

[0033] The length of the bottom rail bracket 1 is calculated according to the height of the shaft. The modular combination of the three rails can be adapted to shafts of any height. The calculation formula for the length a of the bottom rail bracket is:

[0034] a=PH+TH+SH-3163-n×2500,

[0035] Where PH is the pit depth, TH is the lifting height, SH is the top floor height, 760<a≤3260, n represents the number of intermediate guide rail brackets, and takes the maximum value. The variation of the bottom guide rail bracket a is as follows Figure 6 The five transformation specifications G01-G05 are shown.

[0036] The present invention has a modular design of the top, middle and bottom rail mounting brackets, wherein the length of the bottom bracket varies according to the height of the shaft, and the length of the top and middle rail brackets is fixed. The specific modular combination rules are shown in Figure 8 As shown, the rear decorative panel of the shaft with integrated modular design has specific changing rules and synchronized guide rail mounting brackets; the joints can be shielded from light by moving the position of the reinforcing rib plate, thereby improving the quality of the entire ladder; the setting of the anti-loosening bracket ensures the overall stability of the rear decorative panel; the straight connector of the aluminum profile main beam connecting each other between the guide rail mounting brackets also has the function of the guide rail connecting plate, and the traditional guide rail connecting plate can be eliminated. The design is ingenious, the integration is high, and the installation is more efficient; different specifications of sheet metal parts ensure that the mounting brackets are suitable for shafts of different widths; the modular design integrates the bottom, rear, and top connection mechanisms of the shaft, which is convenient for on-site installation and more stable for shaft fixation.

[0037] The front and side layout diagram of the guide rail mounting bracket is as follows: Fig. 9 As shown in the figure, the concept of modular combination is fully reflected, wherein the top and middle guide rail brackets are fixed, the length of the bottom guide rail bracket is a=PH+TH+SH-3163-n×2500, 760<a≤3260, and n takes the maximum value.
