Description

TECHNICAL FIELD

[0001] The present application relates to the elevator technical field, especially to a car for facilitating observation of safety gear friction gap and an observation method. BACKGROUND

[0002] With the 125% safety gear rated speed linkage test becoming universal, the problems that follow, such as: safety gear linkage is not synchronized, safety gear gap does not meet the requirements, wedge and guide rail are not parallel, safety gear is difficult to measure and adjust after the installation of the whole elevator is completed. If the above problems occur, serious accidents are prone to occur during safety gear brake testing. The current solution is only to judge the installation quality by observing whether the left and right gaps of the guide rail and the safety gear are uniform.

[0003] For example, the publication number "CN101806571A" discloses a "safety gear gap measuring ruler", which includes an inclined measuring ruler, a main ruler and an electronic digital display device, characterized in that: the inclined measuring ruler is provided with an inclined ruler body, and a horizontal measuring reference surface and an inclined measuring surface with a certain geometric proportion are arranged on the inclined ruler body to form the main gap measuring surface with the blade measuring surface of the knife-edge measuring claw of the main ruler. The main ruler can slide along the sliding slide and reciprocate relative to the inclined measuring ruler. An electronic digital display device is mounted on the ruler frame of the inclined measuring ruler to display the reading determined by the displacement of the main ruler on a liquid crystal display screen. However, in actual application, when the safety gear is a side-mounted single-wedge safety gear, the practical tool will be interfered by the guide rail during the measurement process. The staff can only visually estimate the approximate gap from the oblique angle, the measured value will be blurred, and only the gap at the upper and lower edges can be observed. SUMMARY

[0004] In view of the problem that the existing technology in the background art causes interference during the measurement process, resulting in inaccurate observation, the present application provides a car for facilitating observation of safety gear friction gap, which can avoid the limitation of the observation angle by the guide rail during the observation process, can make the observation angle directly face the friction gap, and thus improve the observation accuracy and efficiency.

[0005] To achieve the above-mentioned purposes, the present application adopts the following technical solutions.

[0006] The application discloses a car convenient for observing a friction gap of safety gear, which comprises a car body and a bracket frame arranged at the end of the car body, the bracket frame is movably matched with a guide rail, a safety gear assembly is connected to the outer side of the bracket frame, a friction gap is left between the guide rail and the safety gear assembly, the friction gap is a braking distance reserved between the safety gear assembly and the guide rail, and an observation part is arranged in the inner side area of the bracket frame, so that the human eye can observe the state of the friction gap through the observation part. In the prior art, the safety gear gap is generally measured by means of external tools, and in the measurement process, the safety gear bottom plate and the guide rail need to be overcome to interfere with the measuring tool. When the measuring tool cannot be used due to excessive interference factors in the measurement process, the observation can only be carried out in a visual way. However, due to the limitation of the guide rail and the close arrangement of the safety gear assembly to the guide rail, an inclination is generated in the observation process, and thus the observation value is inaccurate and fuzzy. Unlike the prior art, the observation part is arranged in the application, and the observation part is arranged on the side of the friction gap close to the bracket frame. The observation part means that the staff can observe the friction gap outside the bracket frame through the observation part in the inner side of the bracket frame, avoids the interference factors of the guide rail, and enables the staff to observe the friction gap between the safety gear assembly and the guide rail in the inner side of the bracket frame. The friction gap between the safety gear assembly and the guide rail can fall into the visual range of the observation part, and the observation part is arranged on the side of the friction gap close to the bracket frame, and the guide rail is arranged close to the shaft side arm. Therefore, after the elevator is installed, the staff can still have sufficient observation space in the inner side of the bracket frame in the subsequent maintenance process, and the observation close to the shaft is avoided. Since the interference parts of the guide rail and the safety gear bottom plate are reduced at the position, the measuring tool can be directly used for measurement, and the measurement area is not limited to the upper and lower edges of the friction gap. The friction gap is the braking distance reserved between the friction block of the safety gear assembly and the guide rail, and includes the friction gap arranged on one side or both sides of the guide rail.

[0007] As preferred, the observation part comprises an observation outer hole arranged on the bracket frame. The observation outer hole is arranged on the bracket frame. In the application, the observation outer hole needs to be arranged on the bracket frame in the case that the transverse extension of the braking area in contact between the safety gear assembly and the guide rail cannot avoid the structure of the bracket frame. Therefore, the observation outer hole is arranged to observe and measure the friction gap between the safety gear assembly and the guide rail, so that the friction gap between the safety gear assembly and the guide rail can be in the visual range of the observation outer hole on the bracket frame.

[0008] As preferred, the safety pawl assembly comprises a safety pawl bottom plate, the safety pawl bottom plate is provided with a friction block, the friction gap is the gap between the friction block and the guide rail, and the safety pawl bottom plate is provided with an observation inner hole. The observation inner hole is provided on the safety pawl bottom plate. If the safety pawl assembly can avoid the bracket frame and directly observe the friction gap only by providing the observation inner hole, only the observation inner hole needs to be provided. In this case, the observation part only comprises the observation inner hole.

[0009] As preferred, the observation part comprises an observation outer hole provided on the bracket frame, and the observation inner hole is aligned with the observation outer hole. The observation inner hole is aligned with the observation outer hole, so that the friction gap can be directly observed through the observation part. In this case, the observation part comprises the observation outer hole and the observation inner hole. In this case, the line of sight for observing the friction gap cannot avoid the bracket frame and the safety pawl assembly, so the observation inner hole and the observation outer hole need to be provided at the same time and aligned.

[0010] As preferred, the observation part comprises a plurality of observation holes, and each observation hole is aligned with the friction gap. The observation part comprises a plurality of observation holes, and each observation hole can observe the friction gap. During observation, workers can compare the size of the friction gap between each observation hole to judge the parallelism of the friction block in the extension direction of the guide rail.

[0011] As preferred, the observation part is provided with a scale. The observation part is provided with a scale, and the scale is aligned with the friction gap. The scale can quickly measure the friction gap during observation, improving the accuracy of detection.

[0012] As preferred, the safety pawl assembly comprises a friction side surface aligned with the observation part, the safety pawl assembly is provided with an observation groove, the observation groove penetrates the friction side surface, and the width of the observation groove gradually increases in the direction of the side of the observation groove close to the observation part. The safety pawl assembly comprises a friction side surface, the safety pawl assembly comprises a friction block, the friction side surface is the side surface of the friction block, the observation groove penetrates the friction side surface, that is, the end surface of the side of the observation groove close to the observation part can be observed on the observation part. At the same time, since the cross-sectional area of the observation groove is not the same everywhere, the width (cross-sectional area) of the observation groove gradually increases in the direction of the side close to the observation part. Under this structure design, after the worker aligns with the observation part, when the parallelism of the friction block in the transverse direction is offset, the parallelism can be judged by observing whether the edges of the friction block are in the same plane, thereby realizing the parallelism detection of the friction block in the vertical direction of the guide rail.

[0013] The application also discloses a car observation method for facilitating observation of a safety clamp gap, wherein a worker is located at the inner side of the bracket frame, and the friction gap is observed from the observation part and is adjusted correspondingly. By using the car for facilitating observation of the safety clamp friction gap, the worker can be located at the middle area of the inner side of the bracket frame during observation of the friction gap, and the observation efficiency is improved. In addition, since the setting position of the guide rail and the shaft is avoided, the line of sight can be directly aligned with the observation part, and the observation precision of the friction gap is improved.

[0014] As preferred, the observation part comprises a plurality of observation holes, each of the observation holes is arranged along the extension direction of the guide rail, and the worker observes and measures the friction gap in each observation hole to determine the parallelism of the safety clamp assembly in the parallel movement direction of the bracket frame. The observation part is provided with a plurality of observation holes, so as to ensure the detection accuracy of the parallelism, and the parallelism in the extension direction of the guide rail can be quickly adjusted when the parallelism deviates to ensure that the parallelism in the extension direction of the guide rail meets the standard.

[0015] As preferred, the worker is aligned with the observation part, and the edge line of the observation groove close to the guide rail is compared to determine the parallelism of the safety clamp assembly in the vertical movement direction of the bracket frame. When the worker is aligned with the observation part, that is, in the standard position, the edge line of the observation groove close to the guide rail will have different situations due to whether the parallelism in the vertical movement direction of the bracket frame is standard, and the worker can make adaptive adjustment according to the different situations observed. Since the opening of the observation groove close to the observation part is large, the worker can see from the observation part no matter which side the edge line of the observation groove close to the guide rail is inclined to.

[0016] The beneficial effects of the application are as follows:

[0017] (1) The friction gap has sufficient observation space, the interference factors in the observation process are reduced, and the observation precision of the friction gap is improved.

[0018] (2) The observation efficiency is improved, and the friction gap can be observed from multiple dimensions, such as the specific value of the friction gap and the parallelism of the friction block in each direction. BRIEF DESCRIPTION OF DRAWINGS

[0034] The present application will be further described below in conjunction with the drawings and specific examples.

[0035] Example 1:

[0036] As shown in FIGS. Figure 1 , 2 , 6, a car convenient to observe the friction gap of the safety pawl, comprising a car body and a bracket frame 1 arranged at the end of the car body, the bracket frame 1 movably matches a guide rail 2, the bracket frame 1 is connected with a safety pawl assembly 3 outside, a friction gap 5 is left between the guide rail 2 and the safety pawl assembly 3, the friction gap 5 is the brake distance reserved between the safety pawl assembly 3 and the guide rail 2, and further comprising an observation part 4, in the inner side area of the bracket frame 1, the line of sight of the human eye can pass through the observation part 4 to observe the state of the friction gap 5.

[0037] In the prior art, the method for measuring the gap of the safety pawl is to use external tools. When the safety pawl assembly 3 is a side-mounted single wedge block type safety pawl, the safety pawl assembly 3 is located between the bracket and the guide rail 2. In the conventional setting, the size of the friction block 32 on the safety pawl assembly 3 is smaller than the size of the safety pawl bottom plate 31. Therefore, in the measurement process, the interference of the safety pawl bottom plate 31 and the guide rail 2 to the measuring tool needs to be overcome. Even if such interference factors can be overcome during the measurement process, only the gap at the upper and lower edges of the friction gap 5 can be measured. This requires overcoming different interference factors in two different positions to measure twice, and the staff needs to change the measurement position, which affects the measurement efficiency and cannot directly reflect the friction gap 5 in the most critical middle area of the safety pawl assembly 3. When the measurement tool cannot be used due to excessive interference factors during the measurement process, only the visual observation method can be used. However, due to the limitation of the guide rail 2 and the proximity of the safety pawl assembly 3 to the guide rail 2, the observation process will be inclined, which will lead to inaccurate and blurred observation values, and only the upper and lower edges of the friction gap 5 can be observed.

[0038] Unlike the prior art, the observation part 4 is provided in the embodiment. The observation part 4 is arranged on the side edge of the safety pawl assembly 3 (the side of the friction gap close to the bracket frame), which avoids the interference factors of the guide rail 2, so that the staff can observe the friction gap 5 between the safety pawl assembly 3 and the guide rail 2 through the observation part on the inside of the bracket frame. The observation part 4 can be arranged on the bracket frame 1 or the safety pawl assembly 3, and the relative arrangement position of the bracket frame 1 and the safety pawl assembly 3 is used as the basis in the actual production process.

[0039] Wherein if the lateral extension of the brake area of the contact between the safety pawl assembly 3 and the guide rail 2 can avoid the structure of the bracket frame 1, the observation part 4 is provided on the safety pawl bottom plate 31, and if the lateral extension of the brake area of the contact between the safety pawl assembly 3 and the guide rail 2 cannot avoid the structure of the bracket frame 1, corresponding observation part 4 needs to be provided on the bracket frame 1 and the safety pawl bottom plate 31 to avoid blocking the view, and if the installation of the safety pawl bottom plate 31 does not interfere with the lateral observation friction gap 5, only the observation part 4 needs to be provided on the bracket frame 1, wherein if there are other components that interfere with the view on the lateral extension of the brake area of the contact between the safety pawl assembly 3 and the guide rail 2, adaptive avoidance, displacement, hole, etc. are performed without affecting the basic function, as long as the friction gap 5 between the safety pawl assembly 3 and the guide rail 2 can fall within the visible range of the observation part 4, including but not limited to all of the friction gap 5 falling within the visible range, or selecting important nodes on part of the friction gap 5 to fall within the visible range of the observation part 4, so that the entire friction gap 5 can be more accurately and intuitively evaluated.

[0040] Wherein the observation part 4 is provided on the side of the friction gap close to the bracket frame, and the guide rail 2 is provided close to the shaft side arm, so that after the elevator is installed, the worker can still have sufficient observation space on the inside of the bracket frame during subsequent maintenance, avoiding the need to observe close to the shaft; further, the observation part 4 can be provided with structures including but not limited to hollow structures, transparent structures, and the like, which can accurately and directly observe the required friction gap 5 during production; because the various interference components of the guide rail 2 and the safety pawl bottom plate 31 are reduced at this position, direct measurement can also be performed using a measuring tool, and the measurement area is not limited to the upper and lower edge positions of the friction gap 5.

[0041] Embodiment 2:

[0042] As shown in Figure 2 , 3 , the car in the embodiment for facilitating observation of the safety pawl friction gap includes a car body and a bracket frame 1 provided at the end of the car body, the bracket frame 1 movably cooperates with the guide rail 2, the bracket frame 1 is connected with the safety pawl assembly 3 outside, and the friction gap 5 is left between the guide rail 2 and the safety pawl assembly 3, and further includes an observation part 4, the human eye view can penetrate the observation part 4 to observe the state of the friction gap 5 in the inside area of the bracket frame 1, in addition to the above structure, the observation part 4 in the embodiment is an observation hole 41 provided on the bracket frame 1.

[0043] In this embodiment, an observation hole 41 is provided on the bracket frame 1. The reason for providing the observation hole 41 on the bracket frame 1 in this solution is that the lateral extension of the braking area between the safety clamp assembly 3 and the guide rail 2 cannot avoid the structure of the bracket frame 1. Therefore, the observation hole 41 is provided to observe and measure the friction gap 5 between the safety clamp assembly 3 and the guide rail 2, so that the friction gap 5 between the safety clamp assembly 3 and the guide rail 2 can be within the visible range of the observation hole 41 on both sides of the bracket, including but not limited to all the friction gaps 5 between the safety clamp assembly 3 and the guide rail 2, and the friction gaps 5 on some important nodes between the safety clamp assembly 3 and the guide rail 2.

[0044] Example 3:

[0045] like Figure 2 , 3 As shown in Figure 4, the car in this embodiment that facilitates observation of the safety clamp friction gap includes a car body and a bracket frame 1 located at the end of the car body. The bracket frame 1 is movably fitted with a guide rail 2. A safety clamp assembly 3 is connected to the outside of the bracket frame 1. A friction gap 5 is left between the guide rail 2 and the safety clamp assembly 3. It also includes an observation part 4. In the inner area of ​​the bracket frame 1, the line of sight of the human eye can pass through the observation part 4 to observe the state of the friction gap 5. The observation part 4 includes an observation outer hole 41 provided on the bracket frame 1. Based on embodiment 2, the safety clamp assembly 3 includes a safety clamp base plate 31. A friction block 32 is provided on the safety clamp base plate 31. The friction gap 5 is the gap between the friction block 32 and the guide rail 2. An observation inner hole 42 is provided on the safety clamp base plate 31. The observation inner hole 42 is aligned with the observation outer hole 41. In this embodiment, the lateral extension of the braking area that contacts the safety clamp assembly 3 and the guide rail 2 cannot avoid the structure of the bracket frame 1 and the safety clamp base plate 31.

[0046] The safety clamp assembly 3 includes a safety clamp base plate 31 and a friction block 32. The friction block 32 can clamp the guide rail 2 for braking under the drive of the drive component. When the safety clamp assembly 3 is set on the bracket frame 1, the safety clamp base plate 31 is connected to the bracket frame 1. Therefore, the safety clamp base plate 31 will block the friction gap 5. It is necessary to set an observation inner hole 42 on the safety clamp base plate 31. The observation inner hole 42 is aligned with the observation outer hole 41, so that the friction gap 5 can be directly observed through the observation part 43. In this case, the observation part 43 includes an observation outer hole 41 and an observation inner hole 42.

[0047] like Figure 1 , 2As shown, the bracket frame 1 moves vertically along the guide rail 2, and the observation part 4 is located in the transverse direction of the friction gap 5. The bracket frame 1 is connected to the guide rail 2 through the guide shoe 6 and can move along the extension direction of the guide rail 2. The direction in which the bracket frame 1 moves along the guide rail 2 is the vertical direction. The safety hook assembly 3 is arranged between the bracket frame 1 and the guide rail 2, and the observation part 4 is arranged in the transverse direction of the friction gap 5 (i.e., the extension direction of the friction gap close to the inner side of the bracket frame). During observation, the interference of the guide rail 2 and the shaft on the worker can be avoided. In a conventional arrangement, the bracket frame 1 is provided with guide rails 2 and safety hooks on both sides, and the observation part 4 is arranged in the transverse direction. Therefore, the worker can observe the left and right sides of the bracket frame 1 in the middle position, which can quickly observe and verify the friction gap 5 on both sides, thereby improving the work efficiency. The worker in the middle position of the bracket frame 1 can also obtain sufficient observation space. The vertical and transverse directions are defined relative to the conventional elevator movement direction, i.e., the observation direction of the observation part 4 is staggered with the extension direction of the guide rail 2, thereby obtaining sufficient observation space and being able to look straight at the friction gap 5.

[0048] Embodiment 4:

[0049] As shown in Figure 5 , 6 In this embodiment, the car for facilitating observation of the safety hook friction gap includes a car body and a bracket frame 1 arranged at the end of the car body. The bracket frame 1 is movably connected to the guide rail 2. The outer side of the bracket frame 1 is connected to the safety hook assembly 3. The friction gap 5 is left between the guide rail 2 and the safety hook assembly 3. The observation part 4 is arranged in the inner side region of the bracket frame 1. The line of sight of the human eye can pass through the observation part 4 to observe the state of the friction gap 5. In this embodiment, the observation part 4 further includes a plurality of observation holes 43, and each observation hole 43 is aligned with the friction gap 5.

[0050] The observation part 4 comprises a plurality of observation holes 43, each of which can observe the friction gap 5, and each of which is arranged along the extension direction of the guide rail 2, so as to observe each region of the friction gap 5 between the safety pawl assembly 3 and the guide rail 2 in the extension direction of the guide rail 2. During observation, the worker can judge the parallelism of the friction block 32 in the extension direction of the guide rail 2 by comparing the sizes of the friction gap 5 between the observation holes 43. If the friction gap 5 in each observation hole 43 is the same, it can be judged that the parallelism of the friction block 32 relative to the guide rail 2 meets the standard. If the friction gap 5 in each observation hole 43 is different, it is judged that the friction block 32 is offset relative to the guide rail 2 in the movement direction of the guide rail 2, and needs to be adjusted as soon as possible to avoid the situation that the adhesion degree of each region is different when the friction block 32 abuts against the guide rail 2, which affects the braking quality. The working frequency of the safety pawl assembly 3 is generally four times. After the safety pawl assembly 3 works, there is a tendency that the friction loss is different at each place. Whether the friction loss at each place is the same can also be judged by comparing the friction gap 5 in each observation hole 43. Further, each observation hole 43 on the observation part 4 can also be replaced by a long strip-shaped hole, so that the friction gap 5 can be observed more directly and comprehensively.

[0051] In the embodiment, two observation holes 43 are taken as an example. The extension direction of the guide rail 2 is the vertical direction, so the two observation holes 43 are arranged on the same vertical line. During observation, the parallelism in the vertical direction is judged by comparing the friction gap 5 in the two observation holes 43.

It also comprises an observation part 4, and the human eye can observe the state of the friction gap 5 through the observation part 4 in the inside area of the bracket frame 1; the observation part 4 comprises a plurality of observation holes 43, each of which is aligned with the friction gap 5; in this embodiment, a scale is added to each observation hole 43 based on embodiment 4.

[0054] A scale is arranged on each observation hole 43, which is aligned with the friction gap 5, so as to quickly measure the friction gap 5 during observation, and convert the observation of the friction gap 5 into numerical quantification, thereby improving the accuracy of detection.
