Description

Technical Field

[0001] The utility model relates to the technical field of drive machine replacement, in particular to a drive host fixing structure. Background Art

[0002] The escalators or moving walkways in public places such as shopping malls, subways, and stations need to use the drive host as power output. The design life of the drive host is relatively long, about 20 years. When the drive host needs to be replaced, due to the long time span, the original model of the drive host is likely to have been discontinued, and the base size of the new drive host product is different from that of the original model. With the continuous improvement of technology, the new drive host will be smaller and the base will be thinner, resulting in the original clamping and fixing mechanism (i.e., compression code) cannot be directly used for the clamping and fixing of the new host.

[0003] Generally, the original clamping and fixing mechanism needs to be modified through welding to form a structure that adapts to the new drive host. However, due to fire safety requirements, many public places where escalators are used prohibit open flame construction and welding operations, making it difficult to fix the new drive host. Moreover, even if there are some places where welding operations are allowed, the operating space of the escalator maintenance room is limited, making it difficult to guarantee the quality of on-site welding.

[0022] 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.

[0023] like Figure 2 , Figure 4As shown, the utility model provides a driving host fixing structure, which is used to fix the driving host 4 on the crossbeam structure of the steel frame. The crossbeam structure includes a first support beam 1 and a second support beam 2. The crossbeam structure is provided with a fixed pressure code 3 and three movable pressure codes. The fixed pressure code 3 is welded to the first support beam 1. The fixed pressure code 3 is provided with a pressing part 31. The first support beam 1 is connected to a movable pressure code by bolts, and the second support beam 2 is connected to two movable pressure codes by bolts.

[0024] like Figure 1 As shown, in the prior art, the base of the original model of the driving host 4 is placed on the first support beam 1 and the second support beam 2, and a foot 41 on the base is located between the fixed pressure code 3 and the first support beam 1, and is fixed by bolts, and the pressing part 31 presses the foot 41 downward, and the fixed pressure code 3 serves as a pressing and fixing mechanism to fix the entire driving host 4 on the beam structure.

[0025] In this embodiment, if Figure 2-Figure 3 As shown, four feet 41 are arranged on the base of the driving host 4, and the four feet 41 are located at the four corners of the base of the driving host 4. After the driving host 4 is installed, the four feet 41 are arranged at four pressure codes.

[0026] Specifically, an adaptive support structure is arranged between the base of the driving main unit 4 and the crossbeam structure. The support structure is fixed to the base of the driving main unit 4 by bolts. The support structure is in the shape of a plate with uniform thickness. Preferably, the support structure is a transition base plate 5. The thickness, shape and size of the transition base plate 5 can be cut and selected according to actual usage.

[0027] The pressing part 31 of the fixed pressing code 3, the foot 41 below the pressing part 31 and the transition bottom plate 5 are fixed to the first support beam 1 by bolts.

[0028] In this embodiment, the bolts connecting the base of the original model driving host 4 and the pressing code are first removed, the original model driving host 4 is removed, and an adaptive transition base plate 5 is added to the bottom of the base of the newly replaced driving host 4, so that the sum of the base thickness of the newly replaced driving host 4 and the thickness of the transition base plate 5 is adapted to the height of the fixed pressing code 3, and the thickness of the thinner base of the newly replaced driving host 4 is compensated by the transition base plate 5, so that the pressing part 31 of the fixed pressing code 3 can still press the base of the driving host 4, and the pressing part 31, the base foot 41 under the pressing part 31 and the transition base plate 5 are fixed by bolts, so that the newly replaced driving host 4 is accurately positioned and pressed and fixed, and then the three movable pressing codes and the other three base feet 41 are fixed to the beam structure by bolts.

[0029] The present application realizes the clamping and fixing of the new driving main unit 4 without modifying the original fixed clamping mechanism (i.e., the fixed clamping code 3) or slightly modifying it by welding process. This not only meets the requirements of places where open flame construction and welding operations are prohibited, but also avoids the problem of poor weld quality caused by the incompatibility between large welding equipment and the operating space of the escalator maintenance room.

[0030] Working principle: first remove the bolts connecting the base and the pressure code of the original model driving host 4, remove the original model driving host 4, and install an adaptive transition base plate 5 at the bottom of the base of the newly replaced driving host 4, so that the pressing part 31 of the fixed pressure code 3 can still press the base of the driving host 4, and fix the pressing part 31, the base foot 41 under the pressing part 31 and the transition base plate 5 by bolts, so that the newly replaced driving host 4 is accurately positioned and pressed and fixed, and then the three movable pressure codes and the other three base feet 41 are fixed to the beam structure by bolts.

[0031] In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
