TECHNICAL FIELD
[0001] The utility model relates to the technical field of safety production, especially a safety hook loosening alarm device. BACKGROUND
[0002] Safety hook, also known as safety hook or main lock, is the most commonly used connection tool to connect ropes, flat belts and anchor points, equipment, etc. At present, most safety belts for high-altitude operation use mechanical safety hooks, which serve as a powerful line of defense for protecting life and property safety, and have a large social usage amount. However, due to weak safety awareness of users, poor memory and other forgetfulness of hook hanging, some hooks are not effectively and reliably hung on load-bearing railings or pipes during production, which threatens the lives of construction front-line personnel to a certain extent and has great safety hazards. SUMMARY
[0003] The utility model aims to solve at least one of the technical defects.
[0004] Therefore, one purpose of the utility model is to provide a safety hook loosening alarm device to solve the problems mentioned in the background art and overcome the deficiencies in the prior art.

An arc-shaped seat is attached to the surface of the curved hook of the safety hook body. A connecting plate is fixedly connected to one side of the arc-shaped seat. A sliding arc-shaped seat is slidingly connected to one side of the arc-shaped seat and penetrates the arc-shaped seat. A high-position sensor, a control mainboard, an audible and visual alarm and a power box are arranged on one side of the connecting plate. A contact sensor is fixedly installed on the inner wall of the arc-shaped seat. A return spring is fixedly installed on the side of the sliding arc-shaped seat close to the contact sensor. An auxiliary mounting plate is arranged on one side of the arc-shaped seat. An upper arc-shaped positioning seat is fixedly installed on the side of the connecting plate close to the auxiliary mounting plate. The technical effect achieved by the above-mentioned scheme is that a plurality of safety hook bodies are hung on the pipe, then the pipe contacts the sliding arc-shaped seat, and the safety hook body is lowered under the action of gravity, so that the sliding arc-shaped seat moves and contacts one side of the contact sensor. At the same time, the height of the safety hook body is monitored by the high-position sensor. If part of the safety hook body does not contact and the high-position sensor is inconsistent with other data, the control mainboard controls the audible and visual alarm to issue an alarm. This can monitor in real time whether the worker places the hook on the load-bearing rod or the pipe when performing safety construction work, can issue a warning when the hook is not used, and thus can make the work of the worker safer.
[0006] Preferably, the inner part of the arc-shaped seat is provided with a sliding groove, one side of the sliding groove is provided with a through groove matched with the sliding arc-shaped seat, and the contact sensor is fixedly installed in the inner part of the sliding groove. The technical effect achieved by the above scheme is that the through groove can facilitate the corresponding lifting operation of the sliding arc-shaped seat, thereby monitoring whether the safety hook body is hung on the pipe.

The number of the guide rod and the guide plate is two. The technical effect achieved by the above scheme is that the guide plates slide on the surface of the guide rod when the sliding arc-shaped seat moves, thereby guiding the movement of the sliding arc-shaped seat, and enabling it to move more stably.
[0008] Preferably, the number of the reset springs is two, and the two reset springs are symmetrically distributed on the two sides of the contact sensor. There is a gap between the one side of the sliding arc-shaped seat and the sensing end of the contact sensor. The technical effect achieved by the above scheme is that the two reset springs can drive the sliding arc-shaped seat to reset when the safety hook body is separated from the pipe, thereby facilitating subsequent monitoring operation.
[0009] Preferably, the surface of the connecting plate is fixedly installed with a protection box, the control mainboard is fixedly installed in the inner part of the protection box, and the sound-light alarm is fixedly installed on one side of the protection box. The technical effect achieved by the above scheme is that the protection box can protect the control mainboard, thereby ensuring the normal operation of the early warning device.
[0010] Preferably, the control mainboard is electrically connected with the power box, and the control mainboard is electrically connected with the high-position sensor, the sound-light alarm and the contact sensor. The technical effect achieved by the above scheme is that the high-position sensor can cooperate with the suspended safety hook body to monitor the suspended safety hook body, thereby making the monitoring more comprehensive, and the control mainboard is provided with a remote transmission module, thereby enabling the overall monitoring of multiple safety hook bodies.
[0011] Preferably, the auxiliary mounting plate is connected with the arc-shaped seat and the connecting plate by bolts, and one side of the auxiliary mounting plate is fixedly connected with an auxiliary positioning plate. One side of the arc-shaped seat is provided with an auxiliary positioning groove matched with the auxiliary positioning plate. The technical effect achieved by the above scheme is that when the auxiliary mounting plate is installed, the auxiliary positioning plate is inserted into the inner part of the auxiliary positioning groove, the mounting holes can be quickly aligned, thereby facilitating subsequent installation operation.
[0012] Compared with the prior art, the safety hook loosening alarm device has the advantages and beneficial effects that:
[0013] 1、The safety hook loosening alarm device can monitor in real time whether the hook is placed on the load-bearing rod or pipe by the staff during the safety construction operation, and can give a warning when the hook is not used, so that the work of the staff is safer.
