Description

Technical Field

[0001] The utility model relates to the technical field of fences, in particular to a tension fence with a steering pulley block. Background Art

[0002] Tension fence is a collection of electromechanical devices that prevent illegal crossing of obstacles and sense, transmit (alarm), pull, press, and cut obstacle information. It is a safe, reliable, economical and digitally intelligent perimeter anti-intrusion alarm system, mainly composed of support rods and tension wires.

[0003] For example, the adjustable support device for the tension electronic fence disclosed in the utility model with the authorization announcement number CN220081024U drives the first alloy wire to slide along the inner wall of the second slide groove and the outer wall of the electric slide rail through the electric slider, thereby achieving the function of adjusting the position of each first alloy wire. By arranging multiple second alloy wires on the outer wall of the first support column, the problem of the enlarged gap between the fence below and the wall and the reduced anti-theft effect is solved.

[0004] This prior art also has the following problems when used:

[0005] Although the device is equipped with a second alloy wire to block the gap under the fence, when the position of the second alloy wire is fixed and when the height of the first alloy wire is adjusted too high, there is still a large gap between the first alloy wire and the second alloy wire, thereby reducing the fencing effect. In addition, the device adjusts the height of the first alloy wire by manually turning the handle, thereby increasing the work intensity of the staff. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, the utility model provides a tension fence with a steering pulley group. Through the cooperation of multiple pulley groups and adjusting components, when in use, the lifting seat can be moved down to a specified height through the adjusting component. At this time, the lifting seat can drive the pulley group to move down. During the downward movement, the winding motor is started, and the winding motor drives the winding roller to rotate. When the winding roller rotates, the tension line can be kept in a taut state continuously. When the maintenance height is raised, the adjusting motor and the winding motor can be reversed, so that the lifting seat can drive the tension line to extend through the pulley group. At this time, the winding roller can continuously pay out the line, so that the maintenance height can be raised, which greatly increases the practicality and flexibility of the device, and the raising or lowering of the fence height will not affect the size of the gap below the fence.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a tension fence with a steering pulley group, comprising an installation frame, a fixed seat is provided on one side of the installation frame, a lifting seat is provided above the fixed seat, and a plurality of pulley groups are provided inside the lifting seat and the fixed seat, a tension line is surrounded between the pulley groups, and adjustment components are connected to both sides of the lifting seat.

[0008] Preferably, the adjustment assembly is composed of a screw, a double-stage worm, a moving block and a double-stage worm, the two moving blocks are fixedly connected to the two sides of the lifting seat, and a screw is passed through the inside of the moving block, the top ends of the two screws are fixedly connected to worm wheels, and one side of the two worm wheels is meshed with a double-stage worm.

[0009] Preferably, a driving shell is fixedly mounted on the top surface of the mounting frame, and an adjusting motor is fixedly mounted on the outer surface of the driving shell via a fixing frame, and an output end of the adjusting motor is connected to the double-stage worm.

[0010] Preferably, an extension frame is provided on one side of the fixing seat and the lifting seat, a movable groove is opened on the surface of the extension frame and the installation frame, and a screw is placed inside the movable groove.

[0013] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0014] The utility model cooperates with multiple pulley groups and adjustment components. When in use, the lifting seat can be moved down to a specified height through the adjustment component. At this time, the lifting seat can drive the pulley group to move down. During the downward movement, the winding motor is started, and the winding motor drives the winding roller to rotate.
