[0031] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0032] As described in the background technology, in the prior art, the traction machine is generally designed and installed above the machine beam of the elevator machine room to pull the car for vertical movement. Although this design is mature and widely used, it has limitations. Since the traction machine is placed above the machine beam, it is necessary to reserve sufficient machine room height for the traction machine and its necessary maintenance space, which increases the overall height of the elevator machine room and further increases the total height of the building. For high-rise or super-high-rise buildings, this increase in space cost is particularly significant.

[0033] In order to solve this technical problem, the utility model provides a steel belt rack assembly.

[0034] Specifically, please refer to Figure 1-Figure 3 , the steel belt rack assembly specifically includes:

[0035] The frame body 1 has a steel belt traction machine 2 disposed on one side of the bottom of the frame body 1 , and a plurality of steel belt pulleys 3 are disposed inside the frame body 1 .

[0036] The utility model provides a steel belt frame assembly. The present application realizes the downward hanging of the steel belt traction machine 2 by arranging the steel belt traction machine 2 at the bottom of the frame body 1, which significantly reduces the installation height of the steel belt traction machine 2, thereby reducing the top floor height requirement of the elevator room, saving valuable building space for high-rise buildings. The steel belt traction machine 2 is arranged below the frame body 1, so that maintenance personnel can more conveniently approach the steel belt traction machine 2 for inspection and maintenance work, thereby improving maintenance efficiency.

[0037] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0038] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] Example 1, please refer to Figure 1-Figure 3 A steel belt frame assembly includes a frame body 1, a steel belt traction machine 2 is arranged on one side of the bottom of the frame body 1, and a plurality of steel belt pulleys 3 are arranged in the frame body 1. The present application realizes the downward hanging of the steel belt traction machine 2 by arranging the steel belt traction machine 2 at the bottom of the frame body 1, significantly reducing the installation height of the steel belt traction machine 2, thereby reducing the top floor height requirement of the elevator room, and saving precious building space for high-rise buildings. The steel belt traction machine 2 is arranged below the frame body 1, so that maintenance personnel can more conveniently approach the steel belt traction machine 2 for inspection and maintenance work, thereby improving maintenance efficiency.

[0041] Further, such as Figure 1-Figure 4 As shown, the frame body 1 includes two shelf beam bodies 101 , and the steel belt traction machine 2 is arranged between the bottoms of the two shelf beam bodies 101 , and the steel belt traction machine 2 can be supported by the shelf beam bodies 101 .

[0042] Further, such as Figure 1-Figure 4 As shown, a plurality of connecting plates 102 are fixedly connected between the two shelf beam bodies 101, and reinforcing plates 103 are fixedly connected to the sides of the two shelf beam bodies 101 that are away from each other. The connecting plates 102 can connect the two shelf beam bodies 101 together, and the reinforcing plates 103 can reinforce the shelf beam bodies 101.

[0043] Example 2 further optimizes the steel belt rack assembly provided in Example 1. Specifically, Figure 1-Figure 3As shown, the steel belt traction machine 2 includes a supporting frame 201 installed between the bottoms of two shelf beam bodies 101, a traction wheel 203 is arranged between the two supporting frames 201, and a motor 202 connected to the traction wheel 203 is installed on one side of the supporting frame 201. The supporting frame 201 can support the motor 202 and the traction wheel 203, and the motor 202 can drive the traction wheel 203 to rotate.

[0044] Further, such as Figure 2 As shown, a brake 205 is provided at one end of the traction wheel 203 away from the motor 202, and a manual release device 206 is provided on the brake 205. The brake 205 is a double-armature shaft brake disc brake. The brake 205 serves to limit the rotation of the traction wheel 203, and the manual release device 206 can be manually operated. The brake 205 and the manual release device 206 belong to conventional technologies in the field, and therefore will not be described in detail in this article.

[0045] Further, such as Figure 1 As shown, the outer surface of the steel belt pulley 3 is provided with a plurality of second steel belt grooves 301, and the outer surface of the traction wheel 203 is provided with a plurality of first steel belt grooves 204. The second steel belt grooves 301 and the first steel belt grooves 204 are used to limit the steel belt and reduce the deviation of the steel belt during use.

[0046] Further, such as Figure 5 and Figure 6 As shown, a support shaft 302 is provided in the middle of the steel belt pulley 3, and both ends of the support shaft 302 pass through two shelf beam bodies 101 respectively. The steel belt pulley 3 can be supported by the mutual cooperation of the support shaft 302 and the shelf beam body 101.

[0047] Further, such as Figure 1 , Figure 5 and Figure 6 As shown, the outer sides of both ends of the support shaft 302 are provided with grooves 303, and the inner walls of the grooves 303 are plugged with clamping plates 304, which are installed on the shelf beam body 101. The cooperation between the clamping plate 304 and the grooves 303 can limit the support shaft 302 to prevent the support shaft 302 from detaching from the shelf beam body 101. The clamping plate 304 is installed on the shelf beam body 101 by bolts. After unscrewing the bolts, the clamping plate 304 can be removed, thereby releasing the clamping plate 304 from limiting the support shaft 302.

Specifically, Figure 1 and Figure 5As shown, a rope-stopping rod 4 is arranged on the outer side of the steel belt pulley 3, and the two ends of the rope-stopping rod 4 pass through the two shelf beam bodies 101 respectively; mounting holes 401 are opened at both ends of the rope-stopping rod 4, and the mounting holes 401 are used to install pins, and the rope-stopping rod 4 is limited by the pins. During use, the rope-stopping rod 4 can limit the steel belt and guide the running trajectory of the steel belt. It ensures that the steel belt moves on a predetermined path, prevents the steel belt from deviating from the normal operating track, and ensures the stability and safety of the elevator system.
