Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power cable hooks, in particular to a cable safety hook. Background Art
[0002] Power cables are cables for transmitting and distributing electricity. They are used in cities, industrial and mining areas to ensure the normal use of electricity. Due to the large number of power cables laid and the long length of power cables, hooks are needed to support them to prevent the cables from being suspended in the air for a long time, which would reduce the service life of the cables.
[0003] The existing cable safety hooks have the following main drawbacks during use: lack of cable fixation, the cable is easy to slide on the hook, and the surface of the cable is easily damaged due to long-term friction. In addition, in winter, ice is easy to condense on the surface of the cable, which causes the weight of the cable to increase and easily exceed the maximum hanging weight of the hook, causing the hook to fall off. The falling cable may cause harm to nearby personnel. Therefore, there is room for improvement. Utility Model Content
[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.
[0005] To this end, the technical solution adopted by the utility model is: a cable safety hook, comprising: a main body module, the main body module comprising a first U-shaped plate, lower hooks symmetrically fixed on both sides of the first U-shaped plate, upper hooks movably arranged on both sides of the first U-shaped plate, a second U-shaped plate staggered and embedded with the first U-shaped plate, a pressure sensor installed between the first U-shaped plate and the second U-shaped plate, a hanging rope fixed at the bottom end of the second U-shaped plate, and an alarm light installed at the bottom end of the hanging rope.
[0006] Grooves are symmetrically formed on both sides of the first U-shaped plate, a slider is symmetrically fixed to one side of the upper hook, the slider is embedded in the groove, and a spring is fixed on the top of the slider.
[0007] In a preferred example, the utility model can be further configured as follows: one end of the spring is connected to the slider, and the other end is connected to the inner top wall of the groove.
[0008] In a preferred example, the utility model can be further configured as follows: the output end of the pressure sensor is electrically connected to the input end of the alarm light through an electric wire.
[0009] In a preferred example, the present invention can be further configured as follows: circular holes are opened on both sides of the second U-shaped plate.
[0010] In a preferred example, the utility model can be further configured as follows: rubber cushion layers are provided on the relative outer sides of the lower hook and the upper hook.
[0011] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:
[0012] 1. In the utility model, a first U-shaped plate is provided, and lower hooks are symmetrically fixed on both sides of the first U-shaped plate, and an upper hook is movably provided on the first U-shaped plate between the lower hooks. A slider is provided on one side of the upper hook and is embedded in the first U-shaped plate, and a spring is provided between the top of the slider and the inner wall of the first U-shaped plate. When in use, the upper hook is lifted, the cable is placed on the lower hook, and the upper hook is released. Under the action of the spring, the upper hook presses the cable tightly on the lower hook, thereby ensuring the stability of the cable, avoiding damage caused by shaking of the cable and friction with the hook, and being applicable to cables of different sizes, thereby increasing practical performance.
[0013] 2. In the utility model, a second U-shaped plate is arranged to be staggered with the first U-shaped plate, and a pressure sensor is installed between the first U-shaped plate and the second U-shaped plate. The load-bearing capacity of the lower hook is monitored by the pressure sensor. When an ice layer condenses on the surface of the cable and causes the weight of the cable to increase, the downward pulling force borne by the lower hook increases and is transmitted to the pressure sensor through the first U-shaped plate. The pressure sensor detects the increase in pressure value and activates the alarm light after the pressure value reaches the set warning value to alarm nearby personnel and remind them to take shelter. This avoids the increase in weight of the cable after the ice layer condenses and the hook breaking and falling, causing injuries to nearby personnel, thereby further increasing the practical performance.

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0020] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.
[0021] Embodiment 1:
[0022] Combination Figure 1-3 As shown, this embodiment provides a cable safety hook, including: a main body module 100.
[0023] Among them, the main body module 100 includes a first U-shaped plate 110, a lower hook 120 symmetrically fixed on both sides of the first U-shaped plate 110, an upper hook 130 movably arranged on both sides of the first U-shaped plate 110, a second U-shaped plate 140 staggered and embedded with the first U-shaped plate 110, a pressure sensor 150 installed between the first U-shaped plate 110 and the second U-shaped plate 140, a hanging rope 160 fixed at the bottom end of the second U-shaped plate 140, and an alarm light 170 installed at the bottom end of the hanging rope 160.
[0024] The first U-shaped plate 110 is used to install the lower hook 120, and the lower hook 120 is integrally fixed on both sides of the first U-shaped plate 110 for mounting cables. Grooves 111 are symmetrically provided on both sides of the first U-shaped plate 110, and the upper hook 130 is located between adjacent lower hooks 120. A slider 131 is symmetrically fixed on one side of the upper hook 130, and the slider 131 is embedded in the groove 111 to limit the movement of the upper hook 130 and ensure the stability of the upper hook 130 when moving. A spring 132 is fixed on the top of the slider 131, and one end of the spring 132 is connected to the slider 131, and the other end is connected to the inner top wall of the groove 111. When the cable is placed on the lower hook 120, the spring 132 can drive the slider 131 to move downward, and the downward movement of the slider 131 drives the upper hook 130 to press down, pressing the cable tightly on the lower hook 120, ensuring the stability between the cable and the hook, and avoiding the cable shaking and the friction between the hook causing damage.
[0025] In addition, rubber pads are provided on the relative outer sides of the lower hook 120 and the upper hook 130 to increase the friction between the lower hook 120 and the upper hook 130 and the cable, thereby improving the fixing effect of the cable.
[0026] The second U-shaped plate 140 is arranged alternately with the first U-shaped plate 110 . Circular holes 141 are opened on both sides of the second U-shaped plate 140 for bolts to pass through the circular holes 141 to install the second U-shaped plate 140 on the power support.
[0027] The bottom end of the pressure sensor is fixed on the inner bottom surface of the second U-shaped plate 140, and the top end is in contact with the first U-shaped plate 110, so as to monitor the downward pulling force of the first U-shaped plate 110 in real time and start the alarm light 170 when the pressure value reaches the set warning value.
[0028] The hanging rope 160 is used to install the alarm light 170, and the alarm light 170 is used to warn nearby personnel, so as to prevent the cable from being damaged by the increase of weight caused by ice condensation and the hook being broken and falling.
[0029] The working principle and use process of the utility model are as follows: when in use, the upper hook 130 is pulled upwards to put the cable into the lower hook 120, and the upper hook 130 is released. Under the action of the spring 132, the slider 131 is driven to move downward, and the downward movement of the slider 131 drives the upper hook 130 to move downward, pressing the cable onto the lower hook 120 to ensure the stability of the cable. When the cable surface is frozen in winter, the weight of the cable increases, and the pulling force on the lower hook 120 increases. The force borne by the lower hook 120 is transmitted to the pressure sensor 150 through the first U-shaped plate 110. The pressure sensor 150 monitors the pressure value change of the first U-shaped plate 110, and after the pressure value exceeds the set warning value, the alarm light 170 is activated. The alarm light 170 provides a warning to nearby personnel to prevent the cable from being broken by the heavy ice layer and falling off, causing injuries to personnel.
[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
