[0018] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0019] In the present disclosure, unless otherwise stated, the directional words used, such as "up, down, high, low, top, bottom", generally refer to the orientation of the corresponding component or structure in the direction of gravity. "Inside and outside" refer to the inside and outside of the outline of the corresponding component. In addition, it should be noted that the terms used, such as "first, second", etc., are intended to distinguish one element from another and do not have order and importance. In addition, in the description with reference to the accompanying drawings, the same mark in different drawings represents the same element. The above definitions are only used to explain and illustrate the present disclosure and should not be construed as limitations on the present disclosure.
[0020] For ease of understanding, please refer to the attached Figures 1 to 3 , the specific structure and working principle of the elevator detection device disclosed in the present invention are explained in detail in combination with the embodiments.
[0021] The present disclosure relates to a hoist detection device, which is connected to the base 3 of the hoist and can collect data during the operation of the hoist to prevent the cage from getting stuck during the operation of the hoist and causing safety accidents. Figure 1 and Figure 3 The hoist detection device of the present disclosure is connected to the base 3, and includes a fixed seat 1 and a detection member 2. The fixed seat 1 is provided with a mounting position 11, and the mounting position 11 can cooperate with the sheave of the hoist to connect the sheave to the fixed seat 1 to complete the connection between the protection device and the hoist. The detection member 2 is connected to the fixed seat 1 and can detect the gravity applied by the sheave to the fixed seat 1. In some embodiments, the mounting position 11 can cooperate with the bearing seat of the sheave, and the bearing seat of the sheave can be fixedly connected to the mounting position 11 of the fixed seat 1 by fastening bolts 15. Of course, in other embodiments, the mounting method between the mounting position 11 and the sheave can also be other, which can be determined according to actual conditions, and the present disclosure does not limit this.
[0022] When in use, the detection member 2 detects the gravity applied by the sheave to the fixed seat 1 in real time. When the gravity applied by the sheave to the fixed seat 1 is too large, the cage may have stopped running, but the hoist is still lifting the cage, causing the pressure applied by the hoist sheave to the fixed seat to become larger and larger. At this time, the detection member 2 can transmit the detected gravity information to the staff, notifying the staff to deal with possible faults in the hoist, thereby ensuring that no safety accidents will occur later. When the gravity applied by the sheave to the fixed seat 1 is too small, the cage may have stopped running, but the hoist is still lowering the rope, causing the pressure applied by the hoist sheave to the fixed seat to become smaller. At this time, the detection member 2 can also transmit the detected gravity information to the staff, notifying the staff to deal with possible faults in the hoist, thereby ensuring that no safety accidents will occur later. The way in which the detection member 2 transmits information can be a way of information transmission known to those skilled in the art, such as transmission via cables or wireless signals, which will not be elaborated on here.
[0023] The elevator detection device disclosed in the present invention can detect the gravity applied by the elevator sheave on the fixed seat 1 in real time through the fixed seat 1 and the detection member 2, and judge the state of the elevator cage and the elevator according to the magnitude of the gravity applied by the sheave, so as to promptly notify the staff to deal with the problems occurring in the elevator and ensure the stability and safety of the elevator during operation.
[0024] In one embodiment of the present disclosure, see Figure 2 and Figure 3 The fixed seat 1 includes a receiving plate 12 and a fixing plate 13. The fixing plate 13 is provided with two bottoms respectively located on both sides of the receiving plate 12, which are used to contact with the base 3 and fix the fixed seat 1 on the base 3, and form a gap between the bottom surface of the receiving plate 12 and the bottom surface of the fixing plate 13, that is, the top surface of the base 3. The mounting position 11 is formed on the top surface of the receiving plate 12. The detection member 2 is located in the receiving plate 12, and can be located in a cavity inside the receiving plate 12. With such an arrangement, through the gap between the receiving plate 12 and the top surface of the base 3, when the gravity applied by the sky wheel on the receiving plate 12 changes, the receiving plate 12 will produce a certain amount of slight deformation, and the detection part 2 can detect the gravity applied by the sky wheel on the receiving plate 12 through the deformation produced by the receiving plate 12. Such detection can, on the one hand, obtain more accurate data, and on the other hand, it is not easy to cause damage to the detection part 2. If there is no gap between the receiving plate 12 and the base 3, the receiving plate 12 will not be deformed, and the detection part 2 will find it difficult to detect the gravity applied by the sky wheel on the fixed seat 1, thereby causing a safety hazard.
[0025] In one embodiment of the present disclosure, see Figure 2 and Figure 3The receiving plate 12 and the fixing plate 13 are rectangular, and the rectangular receiving plate 12 and the fixing plate 13 are convenient to manufacture and have good stability. The two rectangular fixing plates 13 are respectively located at the edge positions on both sides of the receiving plate 12 and are fixedly connected to the receiving plate 12 to support the receiving plate 12. The fixing plate 13 is also provided with a fixing hole 14, and the fixing hole 14 can cooperate with the fastening bolt 15 to connect the fixing plate 13 to the base 3. The fixed connection method can be directly screwed into the fastening bolt 15 to connect to the base 3, or it can be connected with the assistance of a nut. It will not be described in detail here. In one embodiment of the present disclosure, see Figure 2 and Figure 3 , the receiving plate 12 is also provided with a plurality of fixing holes 14, which are distributed on the edge of the receiving plate 12, and the mounting position 11 is located at the center of the receiving plate 12 to avoid interference with the fixing holes 14. Taking the receiving plate 12 as a rectangular plate as an example, four fixing holes 14 can be provided, which are respectively located at the four corners of the receiving plate 12. By providing the fixing holes 14 on the receiving plate 12, the receiving plate 12 can also be fixedly connected to the base 3 by the fastening bolts 15, thereby increasing the stability of the connection between the fixing seat 1 and the base 3. When the connection between the fixing plate 13 and the base 3 is loosened, the fixed connection between the receiving plate 12 and the base 3 can ensure the stability of the hoist during operation, and provide time for the staff to find the failure of the fixing plate 13.
[0026] In one embodiment of the present disclosure, see Figure 2 and Figure 3 A shock-absorbing pad 121 is provided on the top surface of the receiving plate 12. The shock-absorbing pad 121 can ensure the stability of the overhead sheave on the receiving plate 12, and is not easy to shake during operation, thereby affecting the detection effect of the detection member 2. The material of the shock-absorbing pad 121 can be made of resin or rubber, which can be determined according to actual conditions, and the present disclosure does not limit this.
[0027] In one embodiment of the present disclosure, the detection member 2 is a gravity sensor, which can accurately and effectively detect the weight applied by the sheave on the fixed seat 1, so that the staff can judge whether the hoist has a fault according to the detected gravity data, and avoid the occurrence of safety accidents due to data errors. Of course, in other embodiments, the detection member 2 can also be other types of sensors or detection components, which can be determined according to actual conditions, such as the method and principle of detecting gravity, etc., and the present disclosure does not limit this.
[0028] According to a second aspect of the present disclosure, there is also provided a hoist protection system, comprising the hoist detection device, monitoring device and alarm device described in the above-mentioned embodiments, wherein the monitoring device is connected to the hoist detection device and can receive detection data of the gravity applied by the sheave to the fixed seat 1 detected by the detection member 2, and the alarm device can send out an alarm based on the detection data received by the detection member 2 and the monitoring device to notify the staff that the hoist cage is stuck, so that the staff can deal with it in time to avoid the occurrence of safety accidents.
[0029] In one embodiment of the present disclosure, the hoist protection system of the present disclosure also includes a control device, which can control the alarm threshold of the alarm device according to actual conditions and timely open and close the hoist according to detection data. When used on different hoists, different thresholds are sometimes required for alarm. When the threshold is too low, frequent alarms will occur, which is a problem. If the threshold is too high, there will be a greater safety hazard. Therefore, the control device is required to adjust the alarm threshold of the alarm device according to actual needs. For example, in some embodiments, the threshold of the alarm device is to meet the safety overload of 150% and the limit overload of 200%. If the control device can open and close the hoist, it can close the hoist in time when the staff has not arrived, thereby effectively avoiding the occurrence of safety accidents.
[0030] The third aspect of the present disclosure further provides a hoist, including the hoist protection system described in the above embodiment, and a hoist body. When in use, if the cage of the hoist is stuck, if the hoist is lowering the cage, the gravity applied by the sheave to the fixed seat 1 will decrease, and the alarm device will sound an alarm to notify the staff, and the control device will stop the operation of the hoist to facilitate the staff to carry out subsequent maintenance. If the hoist is lifting the cage, the gravity applied by the sheave to the fixed seat 1 will increase, and the alarm device will also sound an alarm to notify the staff, and the control device will stop the operation of the hoist to prevent safety accidents and facilitate the staff to carry out subsequent maintenance.
[0031] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0033] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
