Description

Technical Field

[0001] The present invention relates to a safety belt hanger, and more particularly to a safety belt hanger for high-altitude maintenance of a transformer substation. Background Art

[0002] When a transformer substation is under maintenance, since the transformer is often installed at a relatively high position, the operator needs to perform high-altitude operations through the cooperation of a safety belt hanger and a lifting seat. However, the existing safety belt hangers often do not have a safety detection and alarm function. Every time it is used, it is detected by the operator himself. Once there is a mistake, it will cause great losses. Therefore, it is particularly important to design a safety belt hanger for high-altitude maintenance of a transformer substation to solve this problem. Summary of the Invention

[0003] The present invention designs a safety belt hanger for high-altitude maintenance of a transformer substation to solve the above problems. A buzzer and an LED lamp assembly triggered to close by a sensor assembly are provided on the main boom body. Through this structure, the operator can be reminded to fasten the buckle, which plays a role in improving the safety performance.

[0004] To solve the above technical problems, the present invention provides a safety belt hanger for high-altitude maintenance of a transformer substation, including a main boom body, a safety belt hanging ring structure connected to one end of the main boom body, and a lifting seat connection assembly provided at the other end of the main boom body. The lifting seat is fixed through the cooperation of the lifting seat connection assembly and a hoop. It is characterized in that: the safety belt hanging ring structure is detachably installed on one side of the main boom body, and a buzzer and an LED lamp assembly are embedded at the end of one end of the main boom body connected with the safety belt hanging ring structure. The buzzer and the LED lamp assembly are triggered to close by a sensor assembly provided in the safety belt hanging ring structure, and a solar power generation assembly for supplying power to the buzzer and the LED lamp assembly is also provided on the main boom body.

[0005] Further: The solar power generation assembly includes a solar power generation panel and a solar charging battery. The solar power generation panel is installed on the other side of the main boom body and is electrically connected to the solar charging battery provided in the main boom body, and the buzzer and the LED lamp assembly are powered by the solar charging battery.

[0006] Still further: The sensor assembly includes a trigger rod and a first contact sensor. The trigger rod is installed in the safety belt hanging ring structure through a return spring. A connection groove for installing the first contact sensor is provided on the inner wall of the safety belt hanging ring structure directly below the trigger rod. The first contact sensor is installed in the connection groove, and the trigger part of the first contact sensor extends out of the connection groove. The position of the trigger rod directly opposite to the first contact sensor is concave, and there is a gap between the trigger rod and the trigger part of the first contact sensor when the trigger rod is not subject to external force.

[0007] Furthermore: The lifting seat connection assembly is composed of a connecting plate, a support plate, a mounting plate, a hoop connecting plate and a hoop connecting frame. One end of the connecting plate extends into the end of the boom main body and is fixedly connected thereto by bolts. The other end of the connecting plate is connected to the support plate and can be adjusted in angle therewith. The support plate is fixed on the mounting plate. The left and right ends of the mounting plate are respectively connected to the hoop connecting plate and the hoop connecting frame through hinge structures.

[0008] Furthermore: The mounting plate is vertically connected to the support plate. An installation groove matching the support plate is formed on the mounting plate. The lower end of the support plate extends into the installation groove and is detachably connected thereto by fixing bolts.

[0009] Furthermore: An adjustable fastening device for connecting the hoop is arranged in the hoop connecting frame. The adjustable fastening device includes a fastening shaft and a one-way locking device. The fastening shaft is rotatably connected in the hoop connecting frame through bearings arranged at both ends. A through groove for the hoop to pass through is formed on the fastening shaft. The one-way locking device is arranged in the hoop connecting frame and is connected to the fastening shaft. The fastening shaft rotates unidirectionally under the limitation of the one-way locking device.

[0010] Furthermore: The one-way locking device includes a locking block and one-way locking teeth. The locking block is installed on the side wall of the hoop connecting frame through a torsion spring. The one-way locking teeth are sleeved on the fastening shaft and are in contact with the locking block. The rotation of the fastening shaft is restricted unidirectionally through the cooperation of the locking block and the one-way locking teeth.

[0011] Still further: A second installation groove is formed on the side of the mounting plate in contact with the lifting seat. A second contact sensor is connected in the second installation groove. The triggering part of the second contact sensor extends out of the second installation groove. The triggering part of the second contact sensor triggers the closing of the buzzer and the LED lamp assembly by contacting the lifting seat.

[0012] After adopting the above structure, the beneficial effects of the present invention are as follows:

[0013] 1. The present invention is provided with a buzzer and an LED lamp assembly triggered to close by a sensor assembly on the boom main body. Through this structure, the operator can be reminded to fasten the buckle, which plays a role in improving the safety performance.
