Description

Technical Field

[0001] The utility model relates to the technical field of pre-assembly of elevator rails, in particular to a pre-assembly positioning structure for elevator rails in an elevator shaft. Background Technique

[0002] With the increasing number of high-rise buildings, the demand for high-speed elevators is also gradually increasing. Most elevators are of the guide rail type, that is, the car runs along the fixed elevator rails during the operation of the elevator. The elevator rails are the safety rails for the elevator to move up and down in the shaft and are one of the main transmission components for the elevator to move up and down.

[0003] At present, the elevator rails of elevators are mostly spliced by multiple T-shaped rails. The T-shaped rail includes a guide surface of the rail, a working surface of the rail, and a bottom plate. The T-shaped rail is vertically installed on the bracket for fixation. The complete elevator rails of high-rise buildings are composed of the head-to-tail splicing of multiple rails. In order to connect and position the multiple rails, a tenon and a mortise are often provided at both ends in the length direction of the rail, and the splicing part of adjacent rails is connected by the tenon and the mortise.

[0004] However, since the splicing of the elevator rails is often completed by hoisting in the elevator shaft, due to the reasons of the light in the elevator shaft and the sizes of the tenon and the mortise, when the staff performs the splicing of the rails, they often need to make multiple adjustments to make the tenon set in the mortise, which affects the installation efficiency of the staff. Summary of the Invention

[0005] The purpose of the utility model is to provide a pre-assembly positioning structure for elevator rails in an elevator shaft, aiming to solve the problem that the elevator rails in the general technology need to be adjusted multiple times during the splicing process, which affects the installation efficiency.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: The pre-assembly positioning structure for elevator rails in the elevator shaft includes a rail. The rail includes a working surface, a guide surface, and a bottom plate, and a tenon and a mortise are respectively provided at both ends in the length direction of the rail. The feature is that a positioning component is provided at the splicing part of the rail. The positioning component includes a base and a mounting plate vertically arranged on the base. An installation groove is opened on the mounting plate and penetrates through the base. The rail is arranged in the installation groove. A plurality of fixing pieces are detachably arranged on the mounting plate, and the fixing pieces are used to fix the mounting plate and the rail;

[0007] A limiting component is arranged at the top of the mounting plate. The limiting component includes a vertically arranged limiting plate, deviation-correcting plates arranged at the left and right ends of the limiting plate, and guide plates abutting against the ends of the deviation-correcting plates arranged at the left and right ends of the limiting plate and deviating from the limiting plate;

[0008] The limit plate is used to limit the installation position of the bottom plate, the guide plate is used to limit the installation of the guide surface, and the alignment plate is used to limit the installation of the bottom plate in the width direction.

[0009] The beneficial effects are as follows: Through the setting of the fixing member and the mounting plate, the mounting plate is fixed to the already installed guide rail. Through the setting of the limiting member, installation limits are provided for the guide rail to be spliced. By using the limit plate to limit the bottom plate of the guide rail, the guide plate to limit the guide surface of the guide rail, and the alignment plate to limit the side surface of the bottom plate of the guide rail, the circumferential installation of the newly spliced guide rail is restricted. As a result, the tenon can be accurately inserted into the mortise, completing the splicing of adjacent guide rails. Furthermore, the workload of adjusting the position of the tenon during splicing by the staff is reduced, and the efficiency of guide rail splicing is improved.

[0010] A further technical solution of the present utility model is that a plurality of first rollers are rotatably arranged on the limit plate in the up and down direction, and the plurality of first rollers abut against the bottom surface of the bottom plate of the guide rail.

[0011] The beneficial effects are as follows: When assembling the guide rail, when the guide rail to be spliced is hoisted and spliced towards the fixed guide rail, the limit plate and the first rollers provide guidance for the newly spliced guide rail while reducing the friction between the bottom surface of the guide rail and the limit plate.

[0012] A further technical solution of the present utility model is that a plurality of second rollers are arranged on the side wall of the mounting groove of the mounting plate in the up and down direction of the mounting plate, and the plurality of second rollers abut against the working surface of the guide rail.

[0013] The beneficial effects are as follows: Through the setting of the second rollers, when setting the mounting plate, the working surface of the guide rail and the side wall of the mounting groove are in rolling friction, reducing the friction between the inner wall of the mounting groove and the working surface of the guide rail. While reducing the probability of damage to the working surface of the guide rail, it facilitates the installation of the positioning structure.

[0014] A further technical solution of the present utility model is that the alignment plates arranged on the left and right sides of the limit plate are respectively inclined towards the left and right directions of the limit plate.

[0015] The beneficial effects are as follows: Through the inclined limit plate, the size of the upper end of the positioning structure is larger than that of the lower end, providing positioning for the guide rail to be spliced. At the same time, the inclined limit plate also guides the guide rail into the mounting groove, thereby improving the splicing efficiency and the accuracy of splicing positioning.

[0016] A further technical solution of the present utility model is that the guide plate is inclined towards the end away from the end where the alignment plate abuts against the guide plate.

[0017] The beneficial effects are as follows: Through the inclined setting of the guide plate, the guide surface of the guide rail is guided, and the guide rail is guided into the mounting groove, thus completing the positioning connection during the assembly of the guide rail.

[0018] A further technical solution of the present utility model is that a reinforcing plate is provided between the deviation rectifying plate and the base, and the upper and lower ends of the reinforcing plate are fixedly connected to the base and the deviation rectifying plate respectively.

[0019] The beneficial effect is that since the guide rails are spliced from bottom to top, when splicing, the guide rails abut against the deviation rectifying plate, thereby increasing the load-bearing capacity of the deviation rectifying plate. By providing the reinforcing plate, the load-bearing capacity of the deviation rectifying plate is improved, and thus the stability of the deviation rectifying plate during use is enhanced.

[0020] A further technical solution of the present utility model is that the fixing member is threadedly connected to the mounting plate. One end of the fixing member facing the mounting groove abuts against the working surface of the guide rail, and a hand wheel is provided at the end of the fixing member away from the mounting groove. The hand wheel is used to drive the fixing member to move towards or away from the mounting groove.

[0021] The beneficial effect is that by driving the fixing member towards or away from the working surface of the guide rail through the hand wheel, the mounting plate and the guide rail are fixed or unfixed. When fixed, it is convenient for the splicing of the guide rails. When unfixed, it is convenient to remove and install it at another installation position for the splicing of the guide rails.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following further describes the specific embodiments of the present utility model in conjunction with the attached Figures 1-3 drawings.

[0027] Referring to Figure 1 and Figure 2 , a pre-assembled positioning structure for an elevator track in an elevator shaft includes a guide rail 1. In this embodiment, the guide rail 1 is a T-shaped guide rail 1. The guide rail 1 includes a guiding surface 3, two working surfaces 2 perpendicular to the guiding surface 3, and a bottom plate 4 perpendicular to the two working surfaces 2. Tenons 5 and mortises 6 are respectively provided at both ends of the guide rail 1 in the length direction. When splicing adjacent guide rails 1, the tenon 5 is inserted into the mortise 6 to connect the heads and tails of the two adjacent guide rails 1.

[0028] Reference Figure 2 and Figure 3 A positioning assembly is installed at the joint of adjacent guide rails 1. The positioning assembly includes a base 7 and a mounting plate 8 vertically arranged on the base 7. The mounting plate 8 is fixedly connected to the base 7. In this embodiment, a mounting groove 9 is opened on the mounting plate 8. The mounting groove 9 passes through the base 7, and the guide rail 1 is inserted into the mounting groove 9.

[0029] Reference Figure 2 and Figure 3 Two rows of fixing members 10 are installed along the height direction on the two side walls of the mounting plate 8 where the mounting groove 9 abuts against the working surface 2 of the guide rail 1. The fixing members 10 penetrate the side walls of the mounting groove 9 into the mounting groove 9. In the present embodiment, the fixing members 10 are bolts, and the fixing members 10 are threadedly connected to the side walls of the mounting plate 8. The fixing members 10 abut against the working surface 2 of the guide rail 1 at one end facing the mounting groove 9, thereby fixing the mounting plate 8 to the guide rail 1.

[0030] Reference Figure 2 A hand wheel 17 is provided at one end of the fixing member 10 away from the mounting groove 9. The fixing member 10 is rotated by the hand wheel 17 so that the fixing member 10 moves away from or close to the mounting groove 9, thereby fixing or releasing the guide rail 1 and the mounting plate 8.

[0031] Reference Figure 1 , Figure 2 and Figure 3 In order to guide and position the guide rail 1 to be spliced, in this embodiment, a limiting member is installed on the top of the mounting plate 8, and the limiting member includes a vertically installed limiting plate 11, a correcting plate 12 installed on the left and right sides of the limiting plate 11, and a guide plate 13 abutting against the correcting plate 12 installed on the left and right ends of the limiting plate 11 at one end away from the limiting plate 11.

[0032] Reference Figure 3 In this embodiment, the limit plate 11 is fixedly mounted on the surface of the base 7 and the limit plate 11 and the mounting groove 9 formed by the mounting plate 8 form a shape matching the cross-sectional size of the guide rail 1. When adjacent guide rails 1 are spliced, the guide rail 1 can be limited, thereby improving the accuracy of assembly.

[0033] Reference Figure 3 In order to facilitate the installation of the guide rail 1 when splicing the guide rail 1, in this embodiment, the limiting plate 11 starts from the same height as the mounting plate 8 and expands to the left and right ends to form a trapezoidal shape.

[0034] Reference Figure 2 and Figure 3The correcting plate 12 is fixedly connected to the limiting plate 11 and the bottom end of the limiting plate 11 is flush with the surface of the mounting plate 8. The relative distance between the bottoms of the correcting plates 12 installed on both sides of the limiting plate 11 is the same as the width of the bottom plate 4 of the guide rail 1. The upper end of the correcting plate 12 is flush with the upper end of the limiting plate 11 and the correcting plates 12 installed on both sides of the limiting plate 11 are tilted toward the left and right directions of the limiting plate 11 respectively, thereby limiting the bottom plate 4 of the guide rail 1.

[0035] Reference Figure 2 and Figure 3 The bottom of the guide plate 13 is flush with the surface of the mounting plate 8 and the guide plate 13 is fixedly connected to the end of the correcting plate 12 facing away from the limiting plate 11. The bottom of the guide plate 13 facing the correcting plate 12 is flush with the side where the mounting groove 9 abuts against the guide surface 3, and the guide plate 13 is inclined toward the end of the guide plate 13 abutting against the correcting plate 12, thereby guiding the guide surface 3.

[0036] Reference Figure 2 and Figure 3 In order to reduce the friction between the bottom plate 4 of the guide rail 1 and the limit plate 11 during the splicing process, in this embodiment, the limit plate 11 is rotatably installed with three rows of first rollers 14, and the surface of the first rollers 14 is higher than the limit plate 11. When the guide rail 1 is installed, the bottom surface of the bottom plate 4 abuts against the first rollers 14, that is, the bottom surface of the bottom plate 4 and the first rollers 14 slide and rub against each other.

[0037] Reference Figure 2 and Figure 3 In order to reduce the friction between the side wall of the mounting groove 9 and the working surface 2 of the guide rail 1 when the mounting plate 8 is installed on the guide rail 1, in this embodiment, the mounting plate 8 is rotatably mounted with two rows of second rollers 15 on the side wall of the mounting groove 9, and the second rollers 15 are in contact with the working surface 2 of the guide rail 1, that is, the working surface 2 of the guide rail 1 and the second rollers 15 slide and rub against each other.

[0038] Reference Figure 1 Since the correcting plate 12 needs to withstand the gravity from the guide rail 1 during installation, in order to improve the stability of the correcting plate 12, in this embodiment, a reinforcing plate 16 is fixedly installed between the correcting plate 12 and the base 7, and the upper and lower ends of the reinforcing plate 16 are fixedly connected to the surface of the base 7 and the bottom surface of the correcting plate 12 respectively.

[0039] The implementation principle of this embodiment is: install the mounting groove 9 on the top of the already fixed guide rail 1, that is, set the mounting groove 9 outside the guide rail 1, and the staff can choose whether to install the mounting plate 8 flush with the surface of the guide rail 1 or make the surface of the guide rail 1 in the mounting groove 9 according to the installation habit, and then turn the hand wheel 17 to fix the mounting plate 8 and the guide rail 1. Due to the second rollers 15 installed on both sides of the mounting groove 9, the distance from the side wall of the mounting groove 9 to the working surface 2 of the guide rail 1 is the same.

[0040] Then, lift the guide rail 1 to be spliced by hoisting and splice it towards the fixed guide rail 1.

[0041] As the hoisted guide rail 1 moves towards the fixed guide rail 1, the side surface of the bottom plate 4 of the hoisted guide rail 1 abuts against the deviation rectifying plate 12 and moves towards the bottom of the deviation rectifying plate 12 along with the inclination of the deviation rectifying plate 12. The guiding surface 3 moves towards the bottom of the guiding plate 13 under the inclination of the guiding plate 13, and the bottom surface of the bottom plate 4 slides along the limiting plate 11.

[0042] When the hoisted guide rail 1 moves to the bottom of the deviation rectifying plate 12 and the guiding plate 13, the hoisted guide rail 1 is aligned with the installation groove 9.

[0043] If the surface of the mounting plate 8 is flush with the surface of the fixed guide rail 1, then the tenon 5 of the hoisted guide rail 1 is inserted into the mortise 6 at this time, and the splicing of adjacent guide rails 1 is completed.

[0044] If the surface of the fixedly installed guide rail 1 is in the installation groove 9, continue to move the hoisted guide rail 1 downward until the tenon 5 is inserted into the mortise 6, and during the movement, the first roller 14 slides relative to the bottom surface of the bottom plate 4, and the second roller 15 slides relative to the working surface 2 of the guide rail 1.

[0045] After the tenon 5 of the hoisted guide rail 1 is inserted into the mortise 6 of the fixed guide rail 1, rotate the hand wheel 17 to release the fixation between the mounting plate 8 and the fixed guide rail 1 by the fixing member 10, and then slide along the length direction of the hoisted and installed guide rail 1 until it slides to the next splicing position.

[0046] At this time, the staff can install the connecting plate to enhance the strength between the spliced guide rails 1.

[0047] After the splicing of the guide rails 1 is completed, take it out from the end of the topmost guide rail 1 for storage.
