AI Technical Summary
In existing forced-drive elevators, broken or loose wire ropes can easily lead to safety hazards. Existing detection devices are not sensitive enough to effectively disconnect the safety circuit.
Design a detection device comprising an upper clamping plate, a lower clamping plate, a tension spring, and a limit switch assembly. A double nut connection is used to achieve stable clamping of the wire rope and disconnection of the safety circuit. The safety circuit is disconnected by the impact action of the striker against the support seat.
It enables sensitive detection of loose or broken wire ropes, ensuring reliable disconnection of the safety circuit and improving elevator safety and detection sensitivity.

Description
TECHNICAL FIELD
[0001] The utility model relates to elevator detection field, concretely is a kind of strong drive elevator steel wire rope detection device. BACKGROUND
[0002] Elevator needs to use steel wire rope when construction, make car move up and down under the dragging of steel wire rope, and the problem of broken wire and broken strand will appear after long time use of steel wire rope, and the phenomenon of rope strand jumping or mutual interference entanglement is easily caused after the broken wire of steel wire rope, above two situations are prone to cause elevator to stop suddenly, and the existing strong drive elevator is generally pulled by 2 steel wire ropes, so there is certain safety hazard in special situations such as the loosening of one of the steel wire ropes or the misoperation of safety tongs or the failure of limit switch. SUMMARY
[0003] The technical problem to be solved by the utility model is to provide a kind of strong drive elevator steel wire rope detection device to solve the problem mentioned in background art.
[0004] In order to solve the above technical problem, the scheme of the utility model is as follows:
[0005] A kind of strong drive elevator steel wire rope detection device, including upper clamping plate, lower clamping plate and tension spring, the first steel wire rope clamping plate is fixedly arranged on the left end of the upper clamping plate, the connecting seat is fixedly arranged in the middle, the support seat and the first recess are fixedly arranged on the right end, the second steel wire rope clamping plate is arranged on the left end of the lower clamping plate, the limit switch assembly and the second recess are fixedly arranged on the right end, the opening is opened in the right end of the upper clamping plate and the lower clamping plate, and the tension spring is arranged in the middle of the opening and is clamped with the upper clamping plate and the lower clamping plate through the first recess and the second recess.
[0006] Preferably, the limit switch assembly includes an inductive device and a striker, the striker is arranged in the inductive device, and the striker is movably connected with the support seat arranged on the upper clamping plate.
[0007] Preferably, the connecting seat, the support seat and the limit switch assembly are connected by double nuts.
[0008] Compared with the prior art, the utility model has the beneficial effects that:
[0009] 1, one or two steel wire ropes loosening or breaking can effectively disconnect the safety circuit, and the action is sensitive, safe and reliable;
[0010] 2, the detection device is clamped between the two steel wire ropes, and the installation is convenient. BRIEF DESCRIPTION OF DRAWINGS

[0015] The specific embodiment of the utility model is further explained in combination with the drawings. It needs to be explained here that the explanation of these embodiments is used to help understanding the utility model, but does not constitute the limitation to the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.
[0016] Referring to Figures 1-4 , a strong drive elevator steel wire rope detection device, including upper clamp plate 1, lower clamp plate 2 and tension spring 3, the upper clamp plate 1 left end is fixedly provided with first steel wire rope clamp plate 101, is fixedly provided with connecting seat 102 in the middle, is fixedly provided with support seat 103 and first recess 104 on the right end, the lower clamp plate 2 left end is provided with second steel wire rope clamp plate 201, and limit switch assembly 21 and second recess 203 are fixedly provided on the right end, the upper clamp plate 1 and the lower clamp plate 2 right end are opened with opening 4, the tension spring 3 is set in the middle of opening 4 and is clamped with the upper clamp plate 1 and lower clamp plate 2 through first recess 104 and second recess 203.
[0017] Specifically, the limit switch assembly 21 includes inductive device 211 and striker 212, the striker 212 is arranged in inductive device 211, the striker 212 corresponds with the support seat 103 arranged on the upper clamp plate 1. Action is sensitive, and can effectively disconnect the safety circuit.
[0018] Further, the connecting seat 102, the support seat 103 and the limit switch assembly 21 all use double-nut connection. By using double-nut connection, it is more safe and effective to control the steel wire rope detection device.
[0019] When using, such as Figure 4As shown, the utility model is installed on two steel wire ropes, the first steel wire rope clamping plate 101 and the second steel wire rope clamping plate 201 are clamped between the two steel wire ropes, the upper clamping plate 1 and the lower clamping plate 2 are clamped in the middle position of the opening 4 through the tension spring 3, the upper clamping plate 1 and the lower clamping plate 2 are tightly buckled through the first recess 104 on the upper clamping plate 1 and the second recess 203 on the lower clamping plate 2, when one steel wire rope is broken, the plunger 212 of the limit switch assembly 21 will hit the support seat 103 under the action of the tension spring 3, thereby breaking the safety circuit, the action is sensitive, the connecting seat 102 is used for the position of connecting the upper clamping plate 1 and the lower clamping plate 2, through the use of double-nut connection, the utility model is more safe and effective.
[0020] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations are made to these embodiments without departing from the principles and spirits of the utility model, still fall into the protection scope of the utility model.
