[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 4 As shown, a traction wheel installation auxiliary frame for elevator installation includes a mounting seat 1, at least two groups of load-bearing pulleys 2 are arranged above the mounting seat 1, and one group of the load-bearing pulleys 2 is composed of two load-bearing pulleys 2 whose axes are parallel to each other; the single load-bearing pulleys 2 between two adjacent groups of load-bearing pulleys 2 correspond to each other one by one and are coaxially arranged; the mounting seat 1 is also provided with a driving device for driving all the load-bearing pulleys 2 to move up and down.

[0028] In this embodiment, two groups of load-bearing pulleys 2 are used.

[0029] Specifically in this embodiment, the mounting base 1 includes a base 11 and side panels 12 respectively arranged on both sides of the base 11 ; the load-bearing pulley 2 is slidably arranged between the two side panels 12 via a sliding bracket 21 .

[0030] Furthermore, reinforcing ribs 13 are provided between the base 1 and the side panels 12 to enhance the overall stability and load-bearing performance of the mounting base 1 .

[0031] As a specific embodiment, a slide rail 31 corresponding to the sliding bracket 21 is provided on the inner side of the side panel 12 (the inner side being the side opposite to the two side panels 12), and the slide rail 31 is extended up and down, and the two ends of the sliding bracket 21 are respectively connected to the corresponding slide rail 31 by sliding blocks 32.

[0032] Preferably, the load-bearing pulley 2 adopts a ball bearing, which has high load-bearing strength and low rotational friction.

[0033] Specifically in this embodiment, a shaft seat 23 corresponding to the load-bearing pulley 2 is disposed on the top of the sliding bracket 21 , and the load-bearing pulley 2 is rotatably disposed on the shaft seat 23 .

[0034] As a specific implementation, the driving device is a screw jack 4. Specifically, the screw jack 4 is fixed on the mounting seat 1, specifically fixed on the base 11 by bolts, and the top of the screw jack 4 is fixedly connected to the sliding bracket 21 by a connecting rod 22.

[0035] Furthermore, a plurality of running wheels 5 are provided at the bottom of the mounting base 1 to facilitate the movement and adjustment of the mounting base 1 as a whole.

[0036] Preferably, the travel wheel 5 is a universal wheel, which is convenient for movement adjustment and angle adjustment in all directions in the horizontal plane.

[0037] Working principle: Figure 3 and Figure 4 As shown, before installing the traction wheel 6 on the power output shaft of the reducer 7, the mounting base 1 is placed near the reducer 7 so that the axis of the load-bearing pulley 2 is roughly parallel to the power output shaft 7 of the reducer 7, thereby forming a preliminary positioning for the traction wheel 6 to be installed.

[0038] During installation, first move the traction wheel 6 to the top of the load-bearing pulley 2, and make the rotating shaft of the traction wheel 6 between the tops of the two load-bearing pulleys 2 in one group. The two groups of weighing pulleys 2 respectively support the rotating shaft parts on both sides of the traction wheel 6; the main body of the traction wheel 6 is between the two groups of load-bearing pulleys 2, ensuring that the traction wheel 6 can rotate freely on the load-bearing pulleys 2.

[0039] Then, the rotating shaft at one end of the traction wheel 6 connected to the reducer 7 is docked with the power output shaft of the reducer 7. During docking, the mounting seat 1 is moved by the walking wheel 5 to adjust the horizontal position of the traction wheel 6. The sliding bracket 21 is further driven to move up and down along the slide rail 31 by adjusting the lifting and lowering of the screw jack 4, thereby adjusting the up and down position of the traction wheel 6, and finally the traction wheel 6 and the power output shaft of the reducer 7 are coaxially arranged; finally, the traction wheel 6 and the power output shaft of the reducer 7 are coaxially connected by a coupling to complete the installation of the traction wheel 6. The traction wheel 6 can rotate freely on the load-bearing pulley 2, and the rotating shaft of the traction wheel 6 can be quickly rotated and adjusted so that the limit joint of the rotating shaft coincides with the coupling, and the installation is completed quickly, saving time and effort.

[0040] It should be noted that, in this embodiment, the gap between the two load-bearing pulleys 2 in one group is determined according to the diameter of the shaft of the traction wheel 6 actually installed, so as to ensure that the gap between the two load-bearing pulleys 2 in one group is smaller than the diameter of the shaft of the traction wheel 6, to prevent the traction wheel 6 from falling off the load-bearing pulley 2, and to ensure that the load-bearing pulley 2 forms a normal support for the shaft of the traction wheel 6. The spacing between two adjacent groups of load-bearing pulleys 2 is smaller than the length of the shaft of the traction wheel 6, so as to ensure that after the traction wheel 6 is placed on the load-bearing pulley 2, a section of the shaft of the traction wheel 6 is left on the outside of the load-bearing pulley 2 (the side opposite to the two groups of load-bearing pulleys 2 is the outside), so as to facilitate the connection between the shaft of the traction wheel 6 and the power output shaft of the reducer 7.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
