Description

Technical Field

[0001] This utility model belongs to the field of elevator speed governor testing technology, specifically relating to an auxiliary support device for testing elevator speed governors. Background Technology

[0002] like Figure 1 The elevator speed governor 100 is a device installed in the elevator machine room, connected to the car via a steel wire rope, to protect the car from overspeed. Its key structure lies in the internal sheave and its internal centrifugal block. When the speed of the sheave exceeds the rated value, the centrifugal block moves under centrifugal force and strikes the electrical switch, subsequently initiating a series of braking actions. As an important component of the elevator safety system, the elevator speed governor requires regular inspection and maintenance using a speed governor testing instrument 200. The speed governor testing instrument 200 typically includes a strong magnetic drive unit 300 and a computer system. The general procedure involves first releasing the tension from the steel wire rope and the sheave of the elevator speed governor 100, then using tools to detach the steel wire rope from the sheave. After connecting the sensors of the computer system to the electrical switch of the elevator speed governor 100, the strong magnetic drive unit 300 drives the sheave to rotate and gradually accelerate. The purpose is to record whether it can successfully trigger the electrical switch and whether the speed at which the electrical switch is triggered is within the specified range. However, the following shortcomings exist in the specific operation process:

[0003] 1. During the stripping of the wire rope, there is a lack of specialized tools, and the wire rope is often pulled manually to remove it. Due to the weight of the wire rope itself and the weight of the tensioning wheel at the bottom of the shaft, this step is time-consuming and labor-intensive.

[0004] 2. As shown after the wire rope is stripped, it is scattered irregularly on the side, which can easily affect subsequent inspection steps;

[0005] 3. During the inspection phase, a worker needs to hold the drive unit for an extended period of time to operate the rope wheel. However, prolonged hand-holding results in poor stability. To ensure the reliability of the results, multiple inspections are required. As the number of inspections increases, the worker will become fatigued, further reducing the stability of the hand-held drive unit and potentially causing danger.

[0006] Based on the above situation, it is necessary to design an auxiliary support device specifically for testing elevator speed governors. Utility Model Content

[0007] The purpose of this invention is to provide an auxiliary support device for testing elevator speed governors, aiming to solve the problem of inconvenient operation during elevator speed governor testing in the prior art.

[0008] To solve the above problems, the utility model adopts the following technical solution:

[0009] An auxiliary support device for testing elevator speed governors includes a frame positioned above the elevator speed governor with its lower end supported on the ground; a rope lifting assembly comprising a sliding frame, a winch, a rope, and a hook, wherein the sliding frame is slidably connected to the top of the frame, the winch is mounted within the sliding frame, the rope is wound around the winch, and the hook is installed at the free end of the rope to secure the wire rope to the elevator speed governor; and a clamping assembly mounted on the side of the frame to fix the strong magnetic drive unit of the elevator speed governor testing instrument.

[0010] The beneficial effects of this utility model are as follows: by setting up a frame and a rope-lifting assembly, the steel wire rope on the rope wheel can be secured from above, and the steel wire rope can be gradually lifted upwards. This completes the stripping of the steel wire rope from the rope wheel while suspending the steel wire rope in the air to prevent it from falling randomly and affecting subsequent inspection work. Furthermore, due to the existence of the sliding frame, the position of the winch can be adjusted, and this feature can be used to adapt to different specifications of elevator speed governors. The clamping assembly on the side of the frame can replace the strong magnetic drive part of the speed governor tester for manual installation, ensuring stability while eliminating the need for a single worker to hold it for a long time. This represents a significant improvement compared to existing technologies.

[0011] Furthermore, the rope-lifting assembly also includes a central rod, a tensioning wheel, and a pulley. The central rod is arranged perpendicular to the moving direction of the sliding frame and fixed within the sliding frame. A set of sides of the sliding frame parallel to the central rod respectively form a winch assembly position and a pulley assembly position, with the winch and pulley respectively mounted in the winch assembly position and the pulley assembly position. The tensioning wheel is installed below the central rod, and the free end of the rope is sequentially wound around the tensioning wheel and the pulley.

[0012] A further beneficial effect of this invention is that by setting tensioning wheels and pulleys, the stability when suspending steel wire ropes is further improved.

[0013] Furthermore, the lifting rope assembly also includes an elastic buffer, the mounting end of which is fixedly connected to the lower end of the intermediate rod, and the tension wheel is mounted on its elastic movable end.

[0014] A further beneficial effect of this invention is that by setting an elastic buffer, the impact force received by the tensioning wheel can be effectively absorbed.

[0015] Furthermore, the elastic buffer mechanism includes a guide post mounting plate, a guide post, a spring, a connecting plate, and a tension wheel mounting plate. The guide post mounting plate is a C-shaped plate, with the outer surface of its upper top plate fixedly connected to the lower end of the intermediate rod. The guide post is arranged in the C-shaped opening groove of the guide post mounting plate and fixedly connected to the inner surface of its upper top plate. The spring is sleeved on the guide post, with one end fixedly connected to the inner surface of the upper top plate of the guide post mounting plate. The connecting piece is fixedly connected to the other end of the spring. The tension wheel mounting plate is fixedly connected to the connecting piece. The rotating shaft of the tension wheel is rotatably connected to the plate surface of the tension wheel mounting plate.

[0016] Furthermore, there are two lifting rope assemblies, the top of the frame is I-shaped, and the sliding frames of the two lifting rope assemblies are respectively arranged in two opening slots on the top of the I-shaped frame and slidably connected to them.

[0017] A further beneficial effect of this utility model is that by setting two sets of lifting components, the overall applicability of the device is improved.

[0018] Furthermore, a limiting baffle is provided at the top of the frame to prevent the sliding frame from detaching.

[0019] A further beneficial effect of this utility model is that the use of a limiting baffle can prevent the sliding frame from coming off.

[0020] Furthermore, the clamping assembly includes a slider, a support, and a clamping head. The slider is slidably connected to the side of the frame along its height direction. The slider has an installation channel that extends through it along the length direction parallel to the elevator speed governor. The support is movably inserted into the installation channel. The clamping head is installed at the end of the support for fixing the strong magnetic drive part of the speed governor tester.

[0021] A further beneficial effect of this utility model is that the height and horizontal position of the clamping component are adjustable, which can also adapt to elevator speed governors of different specifications, mainly to speed governor rope pulleys of different specifications.

[0022] Furthermore, it also includes two sets of fine-tuning bolts. The inner wall of the mounting channel is clearance-fitted with the outer side of the support. The two sets of fine-tuning bolts are respectively threaded to the upper and lower sides of the sliding member, and their ends can pass through the inner wall of the mounting channel to abut against the side of the support. Each set of fine-tuning bolts includes at least two bolts, and they are arranged along the length of the speed limiter.

[0023] A further beneficial effect of this utility model is that by setting two sets of fine-tuning bolts, the support can be deflected at a small angle using a simple structure, thereby fine-tuning the position of its end clamping head.

[0024] Furthermore, it also includes a rotating component, through which the clamping head and the support component are rotatably connected.

[0025] A further beneficial effect of this invention is that when the clamping head is not in use, it can be rotated and folded up to prevent it from taking up too much space.

[0026] Furthermore, the clamping head includes a mounting plate, a clamping plate, and fastening bolts. The mounting plate is connected to the rotating component. There are two clamping plates arranged opposite to each other and slidably connected to the mounting plate. The fastening bolts are threadedly connected to the ends of the two clamping plates away from the mounting plate.

[0027] A further beneficial effect of this invention is that the distance between the two clamping plates is adjustable to accommodate drive units of different sizes.

[0028] Furthermore, V-shaped grooves are respectively provided on the two opposite surfaces of the two clamping plates.

[0029] A further beneficial effect of this invention is that the V-shaped groove can effectively clamp the cylindrical strong magnetic drive part.

[0030] Compared with the prior art, this utility model has the following significant advantages:

[0031] 1. By using a series of structures such as winches to replace manual labor, the wire rope is detached from the rope pulley and erected. The detached wire rope no longer falls randomly, saving time and effort while making the entire testing process more standardized.

[0032] 2. The clamping component replaces manual labor, ensuring more stable operation of the strong magnetic drive unit.

[0033] 3. The device is designed to adapt to different specifications of elevator speed governors through the adjustment mechanism of sliding frame, sliding parts and fine adjustment bolts, so that it has wide applicability. Attached Figure Description

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] like Figure 2As shown, this utility model provides an auxiliary support device for testing elevator speed governors, mainly including a frame 1, a lifting rope assembly 2, and a clamping assembly 3. The frame 1 is a common n-type frame 1 with a top structure and four support legs. The top structure of the frame 1 is arranged above the elevator speed governor 100, and the four support legs are located on the outside of the elevator speed governor 100 shell, so that the entire frame 1 is equivalent to being upside down on the elevator speed governor 100. The overall size of the frame 1 is designed with a certain margin, that is, the length and width of the frame 1 are longer than those of a typical elevator speed governor 100 on the market; the lifting rope assembly 2 includes a sliding frame 201 and a winch 202. The shape of the sliding frame 201 is not limited, but in this embodiment it is a rectangular frame that is slidably connected to the top of the frame 1. The winch 202 is assembled inside the sliding frame 201. Specifically, two support beams arranged in a triangle are fixed at the lower end of the sliding frame 201. The winch 202 is located at the vertices of the triangle and is fixedly connected to the two support beams. The connection method can be welding, bolting, etc. The rope 203 is wound around the winch 202. The hook 204 is installed at the free end of the rope 203 to fasten the wire rope on the elevator speed limiter 100. The form of the hook 204 is not limited and can be a clamp, pliers, or lock. The device can be equipped with a buckle or hook lock, which only needs to be able to lift the wire rope under the drive of the winch 202; the clamping component 3 is installed on the side of the frame 1, specifically on one of the support legs, to fix the strong magnetic drive part 300 of the speed governor tester 200. The auxiliary support device for elevator speed governor testing provided by this utility model can fasten the wire rope on the rope wheel from above by setting the frame 1 and the rope lifting component 2, and gradually lift the wire rope upwards, completing the stripping of the wire rope on the rope wheel, while suspending the wire rope in the air to prevent the wire rope from falling randomly and affecting the subsequent inspection work. Furthermore, due to the presence of the sliding frame 201, it can... The position of the winch 202 is adjusted to accommodate elevator speed governors 100 of different specifications. Specifically, it can accommodate the diameter of different sheaves. There are gaps on both sides of the lower half of the sheave circumference of the wire rope and the sheave. Therefore, this position is more suitable when lifting the wire rope. When dealing with sheaves of different diameters, the sliding frame 201 needs to be moved for adjustment. The clamping component 3 on the side of the frame 1 can replace the strong magnetic drive part 300 of the speed governor tester 200 for manual installation. It ensures stability and eliminates the need for a single worker to hold it for a long time. This is a significant improvement compared to existing technologies.

[0046] In some embodiments, the lifting rope assembly 2 further includes a middle rod 205, a tensioning wheel 206, and a pulley 207. The middle rod 205 is arranged perpendicular to the moving direction of the sliding frame 201 and fixedly connected within the sliding frame 201. The middle rod 205 can be integrally formed with the sliding frame 201 or installed separately. The middle rod 205 divides the interior of the sliding frame 201 into two parts, namely, a set of sides of the sliding frame 201 parallel to the middle rod 205 respectively form the winch 202 assembly position and the pulley 207 assembly position. The winch 202 and the pulley 207 are respectively mounted in the winch 202 assembly position and the pulley 207 assembly position. Specifically, the two support beams mentioned above... The two support beams are welded to the lower middle part of the intermediate rod 205 and the lower middle part of one side of the sliding frame 201 parallel to the intermediate rod 205, respectively. The two support beams are arranged at an angle, and their beams and the parallel of the sliding frame 201 form an inverted triangle. The winch 202 is located at the end of the inverted triangle and is fixed to the two support beams. The pulley 207 is mounted in front of the other side of the intermediate rod 205 and the sliding frame 201 parallel to it. The rotation axis of the pulley 207 is directly rotatably connected to the sliding frame 201. The tension wheel 206 is installed below the intermediate rod 205. The free end of the rope 203 is wound around the tension wheel 206 and the pulley 207 in sequence and finally downwards.

[0047] Based on the previous embodiment, the lifting rope assembly 2 also includes an elastic buffer, which is mainly used to install the tension wheel 206. The elastic buffer includes a mounting end that is fixedly connected to the lower end of the intermediate rod 205, and a movable elastic end that is fitted with the tension wheel 206.

[0048] In some embodiments, the lifting rope assembly 2 is set as two sets. Specifically, the top structure of the frame 1 is an I-shaped steel frame. The sliding frames 201 of the two lifting rope assemblies 2 are respectively arranged in two opening slots at the top of the I-shaped frame 1 and are slidably connected to the I-shaped steel frame. In this embodiment, by setting two sets of lifting rope assemblies 2, the overall applicability of the device is expanded and improved. Moreover, the two lifting assemblies lift the wire rope at the same time, which can ensure that the wire rope is subjected to more even force. Compared with the case where two points are lifted and one point is lifted by the frame 1, the separation effect of the rope pulley is better in the first case. Furthermore, when the wire rope is fully lifted, the space formed is also larger.

[0049] Based on the previous embodiment, a limiting baffle is provided at the top of the frame 1 to prevent the sliding frame 201 from falling out. In this embodiment, the limiting baffle can prevent the sliding frame 201 from falling out, thereby improving the safety of the device.

[0050] In some embodiments, the clamping assembly 3 includes a slider 301, a support 302, and a clamping member 303. The slider 301 is slidably connected to the side of the frame 1 along its height direction. The slider 301 is generally square-shaped with a channel running through it. The support 302 is movably inserted into the mounting channel. The clamping member 303 is installed at the end of the support 302 to fix the strong magnetic drive part 300 of the speed limiter tester 200. Therefore, the height of the clamping member 303 can be adjusted using the slider 301, and the horizontal position of the clamping member 303 can be adjusted using the relationship between the channel of the slider 301 and the support 302. Specifically, to better match the slider 301 and save space, the slider 301 is used to further adjust the clamping member 303. The support legs for the sliding bracket have had their plates removed, leaving only four edges. Sliding parts 301 have through holes corresponding to the four edges, and are inserted through these edges, sliding up and down along the edges. They are then fixed in their current position using bolts, pins, or other locking mechanisms. It is important to note that the position of the sliding through holes on the sliding parts 301 must not interfere with the internal channels. A simple method is to ensure that the diameter of the sliding through holes does not exceed the actual wall thickness of the sliding parts 301, i.e., the distance between the inner wall of the channel and the outer wall of the sliding parts 301. In this embodiment, the above technical solution allows for adjustment of both the height and horizontal position of the clamping parts 303, thus adapting to different specifications of elevator speed governors 100, and primarily to different specifications of sheave pulleys.

[0051] Based on the previous embodiment, as shown in the figure, two sets of fine-tuning bolts 304 are also included. The inner wall surface of the mounting channel is clearance-fitted with the outer side of the support member 302. The two sets of fine-tuning bolts 304 are respectively threaded to the upper and lower sides of the sliding member 301, and their ends can pass through the inner wall surface of the mounting channel to abut against the side of the support member 302. Each set of fine-tuning bolts 304 includes at least two bolts, and they are arranged along the length direction of the support member 302. In this embodiment, by setting two sets of fine-tuning bolts 304, the support member 302 can be deflected at a small angle using a simple structure, with its ends... The position of the clamping member 303 can be fine-tuned. For example, when all the bolts are adjusted up or down simultaneously, the support member 302 can be moved slightly up or down as a whole. When the two bolts on the left side are adjusted up simultaneously and the two bolts on the right side are adjusted down simultaneously, the end of the support member 302 can be shifted slightly downward. Similarly, when the two bolts on the left side are adjusted down simultaneously and the two bolts on the right side are adjusted up simultaneously, the end of the support member 302 can be shifted slightly upward. Thus, the position of the clamping member 303 at the end of the support member 302 can be fine-tuned simply and quickly using four bolts.

[0052] Based on the previous embodiment, a rotating component 305 is also included. The clamping component 303 and the supporting component 302 are rotatably connected via the rotating component 305. In this embodiment, the above-mentioned arrangement allows the clamping component 303 to be rotated and folded away when not in use, preventing it from occupying too much volume. Specifically, as shown... Figure 1 As the strong magnetic drive unit 300 to be clamped is a cylinder with a certain length, the clamping member 303 also needs a certain length to stably clamp the strong magnetic drive unit 300. Therefore, the clamping member will exceed the frame 1 in the working state. However, in the non-working state, it must be transported, and the excess part will occupy an additional volume. Therefore, by setting the rotating member 305, the clamping member 303 can be lowered from the horizontal state to the vertical state in the non-working state. In this way, the clamping member 303 can be parallel to the side of the frame 1, thereby achieving the effect of saving space.

[0053] Based on the previous embodiment, the clamping member 303 includes a connecting plate 3031, a clamping plate 3032, and a fastening bolt 3033. The connecting plate 3031 is connected to the rotating member 305. There are two clamping plates 3032, which are arranged opposite to each other and are slidably connected to the connecting plate 3031 respectively. V-shaped grooves are provided on the two opposite plates of the two clamping plates 3032 respectively. The fastening bolt 3033 is threadedly connected to the end of the two clamping plates 3032 away from the connecting plate 3031.

[0054] Compared with the prior art, this utility model has the following significant advantages:

[0055] 1. By using a series of structures such as the winch 202, the steel wire rope is stripped from the rope wheel and erected instead of being manually removed. The stripped steel wire rope no longer falls randomly, saving time and effort while making the entire testing process more standardized.

[0056] 2. The clamping component 3 replaces manual labor, ensuring more stable operation of the strong magnetic drive unit 300.

[0057] 3. The adjustment mechanism, including the sliding frame 201, the sliding component 301, and the fine-tuning bolt 304, ensures that the device can adapt to different specifications of elevator speed governors 100, making it widely applicable.

[0058] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
