Technical Field

[0001] The utility model relates to the technical field of elevator mainframes, in particular to a device for fixing an elevator mainframe. Background Art

[0002] The elevator host plays an important role in providing power and driving the elevator to move up and down. They mainly use the traction system to make the elevator rise and fall, and control its speed and stop position. They are also responsible for the safety protection of the elevator during operation. Nuts and bolts are used for installation of the elevator, but under the action of vibration force during long-term use of the equipment, the matching installation of nuts and bolts will become loose.

[0003] A Chinese patent discloses an elevator host installation seat (authorization announcement number CN205906863U), which includes: an installation base, a load-bearing beam, a rope sheave 3 and a brake mechanism; the elevator host is installed on the installation base, the installation base has an installation space inside, the base of the elevator host is accommodated in the installation space, the installation base is installed on the load-bearing beam, the load-bearing beams are relatively parallel, the rope sheave 3 is located between two parallel load-bearing beams, the rope on the traction wheel of the elevator host passes around the rope sheave 3, and the brake mechanism is installed on the elevator host. The elevator host installation seat of the utility model is easy to use and has high strength. It can effectively install and fix the elevator host. At the same time, it can meet the installation requirements of the rope sheave 3 and the brake mechanism, which is convenient for long-term use of the elevator.

[0004] This patented technology has the advantage of being convenient when used, but it still has some shortcomings when used. It does not improve the bolt fixation between the mounting base and the load-bearing beam in the traditional installation. When the elevator is running, continuous vibration and impact may cause fatigue of the bolts, which in turn may cause the threads to loosen or the bolts themselves to be damaged, affecting the stability and safety of the elevator host. Therefore, those skilled in the art provide an elevator host fixing device to solve the problems raised in the above background technology. Utility Model Content

[0005] 1. Technical solution

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a device for fixing an elevator main engine, comprising a mounting frame and a driving motor.

[0008] The fixing structure includes two sets of symmetrically distributed screw rods located at the upper end of the mounting frame, a bracket fixed at the lower end of the driving motor, and a nut rotatably sleeved on the outer wall of the screw rod;

[0009] as well as;

[0010] The limiting structure includes support plates fixed on both sides of the upper end of the mounting frame, a clamping block located between the nuts, a limiting ring located at one end of the clamping block, a guide rod located at one side of the limiting ring, and a spring located outside the guide rod and connected to the limiting ring and the support plate at both ends.

[0011] Furthermore, the interior of the bracket is hollow, the whole is frame-shaped, and both ends are open;

[0012] Specifically, the space inside the bracket and the open shape at both ends facilitate the insertion of the screw and provide operating space for the nut to be rotated and sleeved onto the outer wall of the screw. At the same time, the screw and the nut are stored inside the bracket, avoiding direct impact and damage by foreign objects, thereby protecting the screw and the nut.

[0013] Furthermore, two groups of mounting holes are provided inside the lower end of the bracket and are symmetrically distributed and sleeved on the outer side of the screw rod;

[0014] Specifically, the bracket is installed by effectively sleeve-engaging the screw rod through the mounting hole, so that the screw rod is effectively inserted into the interior of the bracket.

[0015] Furthermore, a bearing is embedded and installed inside the limiting ring, and one end of the guide rod is rotatably inserted into the bearing;

[0016] Specifically, the guide rod is rotatably installed through the shaft and the limit plate, and the guide rod can perform rotational motion.

[0017] Furthermore, a sliding sleeve is embedded and installed inside the support plate, one end of the guide rod is slidably inserted into the sliding sleeve, and one end of the guide rod is provided with a handle;

[0018] Specifically, the guide rod is slidably supported by the sliding sleeve, and the sliding sleeve provides rotational support for the guide rod, so that it is convenient to apply lateral force to the guide rod when grasping the handle.

[0019] Furthermore, the outer wall of the handle is sleeved with an anti-slip sleeve, and baffles are provided at both ends of the mounting frame, and the baffles are in the shape of angle plates;

[0020] Specifically, the anti-slip sleeve increases the fit between the user's hand and the handle, improves anti-slip properties, and reduces the problem of detachment. The upward position of the baffle corner plate limits the rotating handle.

[0021] 2. Beneficial effects

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] The utility model provides four fixing screws at the upper end of the mounting frame, and after the driving motor is connected to the bolts, the nuts are rotated and sleeved on the inner wall of the lower end of the bracket, and the bracket and the mounting frame are fixed together, thereby realizing the installation and fixing of the elevator host.

[0024] At the same time, the nuts after installation are symmetrically distributed in two groups, and the elastically installed blocks are inserted into the centers of the corresponding nuts. During the long-term use of the drive motor, the loose nuts are limited by the blocks, which prevents the nuts from loosening, making the nuts more stable during use and avoiding the problem of decreased stability due to loose nuts during the use of the elevator host drive motor. The stability of the elevator host drive motor is improved during use.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] See also Figure 1-Figure 4 As shown, this embodiment is a device for fixing an elevator main engine, including a mounting frame 100 and a driving motor 200.

[0042] The fixing structure 300 includes two sets of symmetrically distributed screw rods 303 located at the upper end of the mounting frame 100, a bracket 301 fixed at the lower end of the driving motor 200, and a nut 302 rotatably sleeved on the outer wall of the screw rod 303;

[0043] The interior of the bracket 301 is hollow, and the whole is frame-shaped, and both ends are open;

[0044] The lower end of the bracket 301 is provided with two sets of mounting holes which are symmetrically distributed and sleeved on the outer side of the screw rod 303;

[0045] Performing use of the fixed structure 300;

[0046] When the elevator drive motor 200 is installed, the mounting holes correspond to the screw rods 303, and are sleeved on the outside of the four screw rods 303. Through the effective sleeve connection between the mounting holes of the bracket 301 and the screw rods 303, the screw rods 303 can be firmly inserted into the bracket 301. The nut 302 is rotated and sleeved on the outer wall of the screw rods 303, and is tightly engaged with the screw rods 303. The mounting frame 100 and the bracket 301 are fixed together to install the elevator host, that is, the drive motor 200. The internal design of the bracket 301 and its open structure at both ends can easily realize the insertion of the screw rods 303 and provide sufficient rotation operation space for the nut 302. At the same time, the components of the screw rods 303 and the nuts 302 are included in the bracket 301, which effectively avoids damage caused by direct impact of foreign objects, thereby fully protecting the screw rods 303 and the nuts 302.

[0047] Example 2

[0048] See also Figure 1-Figure 4 As shown, this embodiment is based on the embodiment 1 and also includes:

[0049] as well as;

[0050] The limiting structure 400 includes support plates 409 fixed on both sides of the upper end of the mounting frame 100, a clamping block 401 located between the nuts 302, a limiting ring 402 located at one end of the clamping block 401, a guide rod 405 located on one side of the limiting ring 402, and a spring 404 located on the outside of the guide rod 405 and connected to the limiting ring 402 and the support plate 409 at both ends.

[0051] A bearing 403 is embedded in the limiting ring 402, and one end of the guide rod 405 is rotatably inserted into the bearing 403;

[0052] A sliding sleeve 406 is embedded and installed inside the support plate 409, one end of the guide rod 405 is slidably inserted into the sliding sleeve 406, and a handle 407 is provided at one end of the guide rod 405;

[0053] The outer wall of the grip 407 is sleeved with an anti-slip sleeve 406, and baffles 408 are provided at both ends of the mounting frame 100, and the baffles 408 are in the shape of angle plates;

[0054] Using the limiting structure 400;

[0055] Grasp the handle 407 to pull the guide rod 405 to both sides, the spring 404 is forced to shrink, and when the handle 407 passes through the baffle 408, the handle 407 is rotated, and the guide rod 405 can rotate through the bearing 403. When the handle 407 corresponds to the baffle 408, the handle 407 is relaxed, and the elastic force of the spring 404 is intercepted by the baffle 408. At this time, the block 401 is located on both sides of the bracket 301, and the bracket 301 and the screw 303 are effectively docked;

[0056] After the bracket 301 is installed, the handle 407 is grasped to rotate the guide rod 405, and the handle 407 is separated from the baffle 408. The elastic support of the spring 404 pushes the limit plate to reset, driving the block 401 to be inserted into the inside of the bracket 301 and located at the center of each group of nuts 302. When the nut 302 is loosened by the vibration force, the rotating nut 302 is limited by the block 401. When the nut 302 is loose, the rotational force is very small. Because the length of the block 401 located inside the bracket 301 is sufficient, the spring 404 can The elastic support of block 401 will not be pushed by the nut 302, and the unstable spring 404 structure will effectively limit the nut 302 under this condition. The nut 302 can be effectively prevented from unnecessary rotation by the limiting block 401 during use, thereby providing additional safety protection. This design can prevent the nut 302 from loosening or rotating disorderly due to external interference or vibration, ensuring that it can be controlled and adjusted as needed, while also reducing the risk of potential damage and instability of the drive motor 200.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
