Description

Technical Field

[0001] The utility model relates to the technical field of elevator control box detection, in particular to a test device for detecting an elevator control box. Background Technique

[0002] The elevator control box is an important part of the elevator equipment. It is a control device installed in the elevator car for passengers to use. The elevator button is one of the parts with the highest frequency of appearance in the elevator control box and is widely used on both the landing call box and the car selection floor panel. The elevator button directly interacts with passengers and may be damaged due to improper use by passengers, harsh environments (such as water ingress or disinfectant), etc. The failure rate is relatively high, and the elevator operation and riding experience will be seriously affected after the button is damaged. Therefore, regular detection is required.

[0003] Among them, the inspection of the button is particularly important. It is necessary to regularly check whether the touch and response of the button are normal. The main operation method is to press the button with a finger. If the button has a jam or no response when pressed, it should be repaired or replaced in time. However, in the actual use process, some elevator control boxes have a large number of floors. If the artificial pressing method is uniformly used for each elevator control box, it will cause too much work burden on the staff, and it is also difficult to control the pressure exerted by the finger, resulting in time-consuming, laborious detection and lack of accuracy. In view of this, we propose a test device for detecting an elevator control box. Content of the Utility Model

[0004] The purpose of the utility model is to provide a test device for detecting an elevator control box, which solves the problems that the work burden of the staff for checking the button is too large, and it is also difficult to control the pressure exerted by the finger, resulting in time-consuming, laborious detection and lack of accuracy.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A test device for detecting an elevator control box includes a support frame. A detection mechanism is arranged on the inner wall of the support frame. The detection mechanism includes guide grooves which are respectively opened on both sides of the support frame. A rotating rod is arranged at the position of the inner wall of the support frame. Both ends of the rotating rod are slidably connected to the inner walls of the guide grooves. A detection ring is connected to the outer wall of the rotating rod.

[0007] Preferably, the detection ring is composed of a hollow rotating ring, a cylinder, a pressing plug, a sealing turntable, a detection cylinder, a detection rod, and a tension spring. The hollow rotating ring is sleeved on the outer wall of the rotating rod. The cylinder is connected to the outer wall of the hollow rotating ring and is distributed at 120 degrees. The pressing plug is slidably connected to the inner wall of the cylinder. The sealing turntable is rotatably connected to one side of the hollow rotating ring. The detection cylinder is connected to the surface of the sealing turntable and is communicated with the inside of the hollow rotating ring. The detection rod is slidably connected to the inner wall of the detection cylinder. The tension spring is connected between the detection rod and the inner wall of the detection cylinder.

[0008] Preferably, the distance between each group of the pressing plugs is the same as the distance between the floor buttons of the elevator control box. The inner wall of the hollow rotating ring is filled with a detection liquid.

[0009] Preferably, racks are connected to the positions on both sides of the inner wall of the support frame below the guide grooves. First gears are meshed above the racks and are sleeved on the outer wall of the rotating rod. Handles are rotatably connected to both ends of the rotating rod.

[0010] Preferably, vertical rods are respectively connected to the positions on the front surface of the support frame corresponding to each group of detection rings. Induction components are connected to the vertical rods, and the distance between the induction components is the same as the distance between the floor buttons of the elevator control box.

[0011] Preferably, the induction component is composed of a connecting block, a chute, a slider, a second gear, and a clamping block. The connecting block is connected to one side of the vertical rod. The chute is opened on the surface of the connecting block. The slider is slidably connected to the inner wall of the chute. The second gear is rotatably connected to one side of the slider. The clamping block is connected to the position on the surface of the connecting block above the second gear. A tooth block is connected to the top of the detection rod. The position of the tooth block corresponds to that of the second gear. A magnet is arranged on one side of the inner wall of the chute close to the tooth block for magnetically adsorbing the slider. A reflective coating is applied to the outer wall of the second gear.

[0012] Preferably, a slideway is connected to the position on the vertical rod corresponding to the detection cylinder, and the inner wall of the slideway is slidably connected to the detection cylinder. Limit blocks are connected to both sides of the detection cylinder, and the limit blocks are slidably connected to the top of the slideway.

[0013] By means of the above technical solution, the present invention provides a test device for detecting an elevator control box, which at least has the following beneficial effects:

[0014] 1. The utility model makes the detection ring and the floor buttons in the same vertical line by attaching the support frame to the surface of the elevator control box. By setting the detection ring, when the rotating rod moves in the guiding groove, due to the rolling of the hollow rotating ring, each protruding extrusion plug outside the hollow rotating ring will press the floor button when it touches the floor button. Due to the resilience of the floor button itself, the extrusion plug will be squeezed and slide into the cylinder, squeezing the detection liquid inside the hollow rotating ring. Under the action of pressure, the detection liquid squeezes the detection rod inside the detection cylinder to make it extend, and judges whether the floor button is normal by the extended length of the detection rod. And by setting a tension spring between the detection rod and the inner wall of the detection cylinder, each time the extrusion plug leaves the floor button during the rolling of the detection ring, the extrusion plug will quickly reset due to the pulling force of the tension spring, so as to facilitate continuous detection during the rolling of the detection ring, greatly improving the monitoring effect and reducing the burden of the monitoring personnel.

[0015] 2. Under the action of the limit block and the slideway limit, the detection cylinder on the detection ring of the utility model is always in a horizontal state. Since continuous detection is carried out during the rolling of the detection ring, but the method of judging by the extended length of the detection rod is very demanding on the eyesight of the staff. Therefore, by setting an induction component at the position of each floor button on the detection cylinder, the staff is reminded whether there is a fault problem. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] A test device for detecting an elevator control box, as Figure 1 , Figure 3 shown, includes a support frame 1. A detection mechanism 2 is provided on the inner wall of the support frame 1. The detection mechanism 2 includes a guide groove 21, and the guide grooves 21 are respectively opened on both sides of the support frame 1. A rotating rod 22 is provided at the position of the inner wall of the support frame 1. Both ends of the rotating rod 22 are slidably connected to the inner wall of the guide groove 21. A detection ring 23 is connected to the outer wall of the rotating rod 22. The detection ring 23 is composed of a hollow rotating ring 231, a cylinder 232, a pressing plug 233, a sealing turntable 234, a detection cylinder 235, a detection rod 236, and a tension spring 237. The hollow rotating ring 231 is sleeved on the outer wall of the rotating rod 22. The cylinder 232 is connected to the outer wall of the hollow rotating ring 231 and is distributed at 120 degrees. The pressing plug 233 is slidably connected to the inner wall of the cylinder 232. The sealing turntable 234 is rotatably connected to one side of the hollow rotating ring 231. The detection cylinder 235 is connected to the surface of the sealing turntable 234, and the detection cylinder 235 is communicated with the inside of the hollow rotating ring 231. The detection rod 236 is slidably connected to the inner wall of the detection cylinder 235. The tension spring 237 is connected between the detection rod 236 and the inner wall of the detection cylinder 235. By arranging the tension spring 237 between the detection rod 236 and the inner wall of the detection cylinder 235, each time the pressing plug 233 leaves the floor button during the rolling process of the detection ring 23, the pressing plug 233 will quickly reset due to the pulling force of the tension spring 237, so as to facilitate continuous detection during the rolling process of the detection ring 23. The distance between each group of pressing plugs 233 is the same as the distance between the floor buttons of the elevator control box. The inner wall of the hollow rotating ring 231 is filled with a detection liquid. When using the detection liquid as the filling medium, the characteristics that the liquid density is higher than the air density and is not easily compressed can be utilized to make the detection result more accurate.

[0025] In this embodiment, during detection, the support frame 1 is attached to the surface of the elevator control box, so that the detection ring 23 is in the same vertical line as the floor button. By setting the detection ring 23, when the rotating rod 22 moves in the guiding groove 21, through the rolling of the hollow rotating ring 231, when each protruding pressing plug 233 on the outside of the hollow rotating ring 231 touches the floor button, it will press down the floor button. Due to the resilience of the floor button itself, the pressing plug 233 will be squeezed and slide into the cylinder 232, squeezing the detection liquid inside the hollow rotating ring 231. Under the action of pressure, the detection liquid squeezes the detection rod 236 inside the detection cylinder 235 to make it extend, and it is judged by the extended length of the detection rod 236 whether the resilience of the floor button is sufficient to avoid the situation that it cannot rebound. And by setting a tension spring 237 between the detection rod 236 and the inner wall of the detection cylinder 235, when the detection ring 23 rolls and each pressing plug 233 leaves the floor button every time, the pressing plug 233 will quickly reset under the action of the tension of the tension spring 237, so as to facilitate continuous detection during the rolling of the detection ring 23, greatly improving the monitoring effect and reducing the burden on the monitoring personnel.

[0026] Embodiment 2

[0027] As Figure 2 shown, on the basis of Embodiment 1, preferably, racks 24 are connected to the positions on both sides of the inner wall of the support frame 1 below the guiding groove 21. Above the racks 24, first gears 25 are meshed and connected, and the first gears 25 are sleeved on the outer wall of the rotating rod 22. The two ends of the rotating rod 22 are rotatably connected with a hand pull 26.

[0028] In this embodiment, the rotating rod 22 is pulled to move by holding the hand pull 26 with the hand. Due to the meshing connection relationship between the rack 24 and the first gear 25, the rotating rod 22 rolls while moving.

[0029] Embodiment 3

[0030] As Figure 1 、 Figure 4As shown in the figure, on the basis of Embodiment 1, preferably, vertical rods 3 are respectively connected to the positions on the front of the support frame 1 corresponding to each group of detection rings 23. An induction component 31 is connected to the vertical rods 3, and the distance between the induction components 31 is the same as the distance between the floor buttons of the elevator control box. The induction component 31 is composed of a connection block 311, a chute 312, a slider 313, a second gear 314, and a clamping block 315. The connection block 311 is connected to one side of the vertical rod 3. The chute 312 is opened on the surface of the connection block 311. The slider 313 is slidably connected to the inner wall of the chute 312. The second gear 314 is rotatably connected to one side of the slider 313. The clamping block 315 is connected to the position on the surface of the connection block 311 above the second gear 314. A tooth block 32 is connected to the top of the detection rod 236. The position of the tooth block 32 corresponds to that of the second gear 314. And a magnet is arranged on one side of the inner wall of the chute 312 close to the tooth block 32 for magnetically adsorbing the slider 313. A reflective coating is applied to the outer wall of the second gear 314. A slideway 33 is connected to the vertical rod 3 at the position corresponding to the detection cylinder 235, and the inner wall of the slideway 33 is slidably connected to the detection cylinder 235. Limit blocks 34 are connected to both sides of the detection cylinder 235, and the limit blocks 34 are slidably connected to the top of the slideway 33.

[0031] In this embodiment, under the limiting action of the limit block 34 and the slideway 33, the detection cylinder 235 on the detection ring 23 is always in a horizontal state. Since continuous detection is carried out during the rolling process of the detection ring 23, but the method of judging by the extended length of the detection rod 236 is very demanding on the eyesight of the staff. Therefore, by setting the induction component 31 at the position of each floor button of the extrusion plug 233 on the detection cylinder 235, it is reminded whether there is a problem of failure. Whenever the detection rod 236 extends when being extruded due to the extrusion plug 233 contacting the floor button, if the resilience of the floor button is insufficient or stuck, the extended length of the detection rod 236 is short and the tooth block 32 cannot contact the second gear 314 for meshing. At this time, the second gear 314 does not rotate, and the button here is the one with insufficient resilience and needs to be repaired. If the resilience of the floor button is normal, the extended length of the detection rod 236 is just right, so that the tooth block 32 contacts the second gear 314 for meshing, and the second gear 314 rotates. The reflective coating on the surface of the second gear 314 flashes due to rotation. The button here is the one with normal resilience and does not need to be repaired. If there is a protruding foreign object on the surface of the floor button, when the extended length of the detection rod 236 is long, the tooth block 32 will push up the second gear 314, causing the slider 313 to slide in the chute 312, so that the second gear 314 contacts the clamping block 315 and blocks the second gear 314 from rotating.

[0032] When a test device for detecting an elevator operation box of the present utility model is in use, during detection, the support frame 1 is attached to the surface of the elevator operation box, so that the detection ring 23 and the floor button are in the same vertical line. The rotating rod 22 is pulled to move by holding the hand pull 26 with the hand. Due to the meshing connection relationship between the rack 24 and the first gear 25, the rotating rod 22 rolls while moving. Due to the rolling of the hollow rotating ring 231, when each protruding pressing plug 233 on the outside of the hollow rotating ring 231 touches the floor button, the floor button will be pressed down. Due to the resilience of the floor button itself, the pressing plug 233 will be squeezed and slide into the cylinder 232, squeezing the detection liquid inside the hollow rotating ring 231. Under the action of pressure, the detection liquid squeezes the detection rod 236 inside the detection cylinder 235 to make it extend. And by judging the extended length of the detection rod 236, it is determined whether the resilience of the floor button is sufficient to avoid the situation that it cannot rebound. And by setting a tension spring 237 between the detection rod 236 and the inner wall of the detection cylinder 235, when each pressing plug 233 leaves the floor button during the rolling of the detection ring 23, the pressing plug 233 will quickly reset due to the pulling force of the tension spring 237, so as to facilitate continuous detection during the rolling of the detection ring 23, greatly improving the monitoring effect and reducing the burden on the monitoring personnel. Under the limiting action of the limiting block 34 and the slideway 33, the detection cylinder 235 on the detection ring 23 is always in a horizontal state. Since continuous detection is carried out during the rolling of the detection ring 23, but the method of judging by the extended length of the detection rod 236 is very demanding on the eyesight of the staff. Therefore, by setting an induction component 31 at the position of each floor button of the pressing plug 233 on the detection cylinder 235, it is reminded whether there is a fault problem. Whenever the detection rod 236 extends due to being squeezed by the pressing plug 233 touching the floor button, if the resilience of the floor button is insufficient or stuck, the extended length of the detection rod 236 is short and the tooth block 32 cannot contact the second gear 314 for meshing. At this time, the second gear 314 does not rotate, and the button here is the one with insufficient resilience and needs to be repaired. If the resilience of the floor button is normal, the extended length of the detection rod 236 is just right, the tooth block 32 contacts the second gear 314 for meshing, and the second gear 314 rotates. The reflective coating on the surface of the second gear 314 flashes due to rotation, and the button here is the one with normal resilience and does not need to be repaired. If there is a protruding foreign object on the surface of the floor button, when the extended length of the detection rod 236 is long, the tooth block 32 will lift the second gear 314, causing the slider 313 to slide in the chute 312, so that the second gear 314 contacts the latch 315 and blocks the second gear 314 from rotating.
