Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a real-time detection device for elevator steel cables. Background Technique

[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car moves on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15° to the plumb line.

[0003] In the prior art, the maintenance of elevator steel cables is carried out by maintenance personnel through regular inspections and maintenance, or by overhaul when a failure occurs. It is impossible to achieve real-time detection of elevator steel cables, and thus it is impossible to timely understand the real-time state of elevator steel cables, which poses certain potential safety hazards.

[0004] Therefore, a real-time detection device for elevator steel cables is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a real-time detection device for elevator steel cables, comprising: an installation shell, two limiting wheel assemblies are arranged inside the installation shell, a movable wheel assembly is arranged inside the installation shell, a detection assembly is arranged on one side of the installation shell, and fixing assemblies are arranged at both ends inside the installation shell.

[0007] As a preferred embodiment, movable grooves are respectively formed on both sides inside the installation shell.

[0008] As a preferred embodiment, the limiting wheel assembly includes a support shaft, both ends of the support shaft are respectively fixedly installed on both sides inside the installation shell, and a first pulley is sleeved on the surface of the support shaft through a bearing.

[0009] As a preferred embodiment, the movable wheel assembly includes an installation rod, a second pulley is sleeved on the surface of the installation rod through a bearing, and rollers are installed at both ends of the installation rod through bearings.

[0010] As a preferred embodiment, the surfaces of the two rollers are respectively movably arranged inside the two movable grooves.

[0011] As a preferred embodiment, the detection component includes a mounting plate, one side of the mounting plate is fixedly mounted on one side of the mounting shell, an S-shaped tension sensor is fixedly mounted on one side of the mounting plate, one side of the S-shaped tension sensor is fixedly connected to a connecting plate, both ends of one side of the connecting plate are fixedly mounted with strong tension springs, one end of the two strong tension springs are fixedly connected to a connecting sleeve plate, and the two connecting sleeve plates are respectively fixedly mounted on the surfaces of the two ends of the mounting rod.

[0012] As a preferred embodiment, the fixing assembly includes a bidirectional threaded rod and a sliding rod, one end of the sliding rod is fixedly installed on both sides of the interior of the mounting shell, one end of the bidirectional threaded rod is installed on one side of the interior of the mounting shell through a bearing, and the other end of the bidirectional threaded rod passes through the interior of the mounting shell through a bearing and is provided with a clamping handle, both ends of the surfaces of the bidirectional threaded rod and the sliding rod are sleeved with splints, and anti-slip pads are fixedly installed on opposite sides of the two splints.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. The utility model is installed before the steel cable is fixed during the installation of the elevator, and the device is fixed above the elevator car. When in use, the elevator steel cable is first passed through the upper two-way threaded rod and the inside of the sliding rod, bypassed the left side of the surface of the upper pulley one, bypassed from the right side of the surface of the pulley two, and then bypassed the left side of the lower pulley one, and finally passed out from the lower two-way threaded rod and the inside of the sliding rod. After the steel cable is installed, by rotating the upper and lower clamping handles, the two-way threaded rod drives the clamping plates and anti-slip pads on both sides to move to the middle to clamp the steel cable for fixing, which is convenient for installation and fixing.

[0015] 2. In the utility model, after the steel cable is fixed, it will be tightened, and the connecting sleeve, strong tension spring and connecting plate will be pulled by pulley 2 to apply tension to the S-type tension sensor. The S-type tension sensor is electrically connected to the external control terminal, and can transmit the tension signal to the external control terminal in real time. During normal use, the slight shaking of the elevator steel cable will cause a small value fluctuation on the S-type tension sensor. Since the elevator will be pulled by multiple steel cables, once a steel cable is loose or a large amplitude vibration occurs, the tension applied to the S-type tension sensor by pulley 2 will be abnormal, thereby reminding the staff to carry out timely maintenance and eliminate safety hazards in time.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: a real-time elevator cable detection device, including: an installation shell 1, two limit wheel assemblies 2 are arranged inside the installation shell 1, a movable wheel assembly 3 is arranged inside the installation shell 1, a detection component 4 is arranged on one side of the installation shell 1, and fixing components 5 are arranged at both ends inside the installation shell 1.

[0025] Specifically: the installation shell 1 plays a role of installing and supporting each component. The two limit wheel assemblies 2 cooperate with the pulley 2 302 to make the elevator cable generate a pulling force on the S-type tension sensor 402. The detection component 4 measures and transmits the pulling force data of the cable in real time, and the fixing component 5 facilitates the installation and fixation of the device.

[0026] In one embodiment, movable grooves 101 are opened on both sides inside the installation shell 1.

[0027] Specifically: the movable grooves 101 facilitate the movement and installation of the rollers 303, and at the same time play a limiting role on the installation rod 301 through the rollers 303.

[0028] In one embodiment, the limit wheel assembly 2 includes a support shaft 201. Both ends of the support shaft 201 are fixedly installed on both sides inside the installation shell 1, and a first pulley 202 is sleeved on the surface of the support shaft 201 through a bearing.

[0029] Specifically: The support shaft 201 serves to install the first pulley 202, and the first pulley 202 serves to limit the elevator steel cable.

[0030] In one embodiment, the movable wheel assembly 3 includes an installation rod 301. A second pulley 302 is sleeved on the surface of the installation rod 301 through a bearing, and rollers 303 are installed at both ends of the installation rod 301 through bearings.

[0031] Specifically: Both ends of the surface of the installation rod 301 are movably embedded in two movable slots 101, and the second pulley 302 cooperates with the two first pulleys 202 to limit the steel cable.

[0032] In one embodiment, the surfaces of the two rollers 303 are respectively movable inside the two movable slots 101.

[0033] Specifically: The rollers 303 are movably installed in the movable slots 101, enabling the installation rod 301 to move flexibly.

[0034] In one embodiment, the detection assembly 4 includes an installation plate 401. One side of the installation plate 401 is fixedly installed on one side of the installation shell 1. An S-shaped tension sensor 402 is fixedly installed on one side of the installation plate 401. A connecting plate 403 is fixedly connected to one side of the S-shaped tension sensor 402. Two strong tension springs 404 are fixedly installed at both ends of one side of the connecting plate 403. One end of each of the two strong tension springs 404 is fixedly connected to a connecting sleeve plate 405, and the two connecting sleeve plates 405 are respectively fixedly sleeved on the surfaces of both ends of the installation rod 301.

[0035] Specifically: The strong tension springs 404 respectively apply tension to the S-shaped tension sensor 402 and the installation rod 301 through the connecting plate 403 and the connecting sleeve plates 405. When the second pulley 302 is limited by the steel cable, the tension generated by the strong tension springs 404 on the S-shaped tension sensor 402 is fixed. When the steel cable is loose or shakes, the limit applied to the second pulley 302 shakes, thereby causing the tension of the strong tension springs 404 to fluctuate, and the data detected by the S-shaped tension sensor 402 also fluctuates.

[0036] In one embodiment, the fixing assembly 5 includes a bidirectional threaded rod 501 and a sliding rod 502, one end of the sliding rod 502 is fixedly installed on both sides of the inside of the mounting shell 1, one end of the bidirectional threaded rod 501 is installed on one side of the inside of the mounting shell 1 through a bearing, and the other end of the bidirectional threaded rod 501 passes through the inside of the mounting shell 1 through a bearing and is equipped with a clamping handle 505, both ends of the surfaces of the bidirectional threaded rod 501 and the sliding rod 502 are sleeved with clamps 503, and anti-slip pads 504 are fixedly installed on the opposite sides of the two clamps 503.

[0037] Specifically: when the bidirectional threaded rod 501 rotates, it can drive the clamping plates 503 at both ends to move synchronously in opposite directions. The sliding rod 502 is movably embedded in the clamping plate 503 to play the role of limiting support. The anti-slip pad 504 increases friction. The clamping handle 505 is a common locking device in the prior art. The specific mechanism will not be repeated here.

[0038] Working principle: This device is installed before the steel cable is fixed during elevator installation. The device is fixed above the elevator car. When in use, the elevator steel cable is first passed through the upper two-way threaded rod 501 and the sliding rod 502, bypassed the left side of the surface of the upper pulley 202, bypassed the right side of the surface of the pulley 2 302, and then bypassed the left side of the lower pulley 202, and finally passed out from the lower two-way threaded rod 501 and the sliding rod 502 (as shown in the attached figure). Figure 5 , after the steel cable is installed, the upper and lower clamping handles 505 are rotated to drive the clamping plates 503 and the anti-skid pads 504 on both sides to move to the middle to clamp the steel cable for fixing through the bidirectional threaded rod 501, so as to facilitate installation and fixing; after the steel cable is fixed, it will be tightened, and the connecting sleeve 405, the strong tension spring 404 and the connecting plate 403 will be pulled through the pulley 302 to apply tension to the S-type tension sensor 402, and the S-type tension sensor 402 is electrically connected to the external control terminal, and the tension signal can be transmitted to the external control terminal in real time. In normal use, the elevator steel cable will cause a small value fluctuation to the S-type tension sensor 402 due to the slight shaking caused by the elevator steel cable. Since the elevator will be pulled by multiple steel cables, once a steel cable is loose or vibrates to a large extent, the tension applied to the S-type tension sensor 402 by the pulley 302 will be abnormal, thereby reminding the staff to carry out timely maintenance and eliminate safety hazards in time.
