Description

Technical Field

[0001] This utility model belongs to the field of cable laying technology, specifically relating to a cable laying device for broadcast television coverage. Background Technology

[0002] Because broadcasting and television work is related to video transmission, a large amount of supporting cable laying work is carried out to maintain the normal operation of related equipment and to achieve stable signal transmission.

[0003] Chinese patent document CN220914859U discloses a broadcast and television coverage cable erection device. The device uses a rotating adjusting screw to raise and lower the broadcast cable limiting ring, making the height of the cable passing through the limiting ring adjustable. The rotating handwheel causes the support column to rotate the broadcast cable limiting ring, adjusting the angle between the cable and the limiting ring to reduce cable wear. The rotating locking bolt causes the arc-shaped clamp to press down, clamping and fixing the broadcast cable.

[0004] However, in the existing technology, although the erection device can fix the cable and change its direction with less wear, it is difficult to quickly separate the cable that has been inserted into the erection device from the device during later maintenance or replacement. Therefore, a broadcast television coverage cable erection device is proposed. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0028] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0029] like Figures 1-5 As shown, a broadcast television coverage cable erection device includes a loading component 1 that can adjust the erection height of the cable, an erection component 2 that allows the cable to be easily installed and removed within the device, and an adjustment component 3 that can adjust the fixing effect of the device on the cable below the erection component 2.

[0030] In this embodiment: the loading component 1 includes a fixed frame 101, screw holes 102 are provided on both sides of the fixed frame 101, a lifting frame 103 is movably connected to the front of the fixed frame 101, and a connecting bolt 104 is fixedly connected between the fixed frame 101 and the lifting frame 103.

[0031] The fixed frame 101 is slidably connected to the lifting frame 103; the fixed frame 101 is fixed at the position where the cable needs to be laid by inserting external fasteners such as bolts into the screw holes 102, thus completing the installation of this device. The lifting frame 103, which can slide relative to the fixed frame 101, is fixed to the fixed frame 101 by connecting bolts 104.

[0032] In this embodiment: the erection component 2 includes a clamping component that can effectively fix cables of various specifications, a reversing component that can prevent excessive bending when the cable changes direction, and a lateral component that can quickly fix the cable in or remove it from the device under the action of the adjustment component 3. The lateral component includes a first carrier 201 movably mounted on the lifting frame 103, a second carrier 202 provided on one side of the first carrier 201, a vertical pole 203 fixedly connected to the rear of the second carrier 202, a slide 204 movably mounted between the second carrier 202 and the vertical pole 203, and a connecting rod 205 movably connected between the first carrier 201 and the slide 204. The clamping component includes a rotating shaft 206 movably mounted in front of the slide 204, a clamping wheel 207 fixedly connected to the outer side of the rotating shaft 206, and a slider 208 movably connected to the first carrier 201. A first knob 209 is fixedly mounted on both sides of the slider 208, and a rotating rod 210 is movably mounted on the slider 208.

[0033] The first carrier 201 and the second carrier 202 are both slidably connected to the lifting frame 103. The second carrier 202 and the upright 203 are both slidably connected to the slide 204. The first carrier 201 and the slide 204 are both rotatably connected to the connecting rod 205. The slide 204 is rotatably connected to the rotating shaft 206. The first carrier 201 is slidably connected to the slider 208. The slider 208 is rotatably connected to the rotating rod 210.

[0034] The first carrier 201 is used to install the connecting rod 205 and the slider 208, and the second carrier 202 is used to install the upright 203 and the slide 204. The connecting rod 205 changes the direction of the movement of the first carrier 201 relative to the second carrier 202 and transmits it to the slide 204, allowing the slide 204 to slide and rise relative to the second carrier 202 and the upright 203. The movable range of the slide 204 is limited by the second carrier 202, the upright 203, and the connecting rod 205, and the rotating shaft 206 is installed on it. The rotating shaft 206 allows the clamping wheel 207 to rise with the slide 204. The device can be lowered and rotated. The clamping wheels 207 installed in front of the lower slide 204 support the cable to be laid. The clamping wheels 207 installed in front of the higher slide 204 press down the cable to be laid. The slider 208 drives the rotating rod 210 to move longitudinally on the first carrier 201. The friction between the first carrier 201 and the slider 208 is adjusted by the first knob 209 to stabilize the longitudinal position of the slider 208 on the first carrier 201. The rotating rod 210, which can rotate relative to the slider 208, limits the degree of bending when the cable is led out of the device.

[0035] In this embodiment: the adjustment component 3 includes a support 301 fixedly connected to the lower part of the lifting frame 103, a bidirectional lead screw 302 movably connected between the supports 301, a second knob 303 fixedly connected to one end of the bidirectional lead screw 302, and a crossbar 304 fixedly connected inside the lifting frame 103.

[0036] The support 301 is rotatably connected to the double-acting screw 302; the double-acting screw 302 is installed below the lifting frame 103 through the support 301, and the double-acting screw 302 and the crossbar 304 together limit the movable range of the first carrier 201 and the second carrier 202 on the lifting frame 103. The double-acting screw 302 can be easily rotated through the second knob 303, and the rotated double-acting screw 302 drives the first carrier 201 and the second carrier 202 to move towards each other or away from each other.

[0037] Working principle: When the installation of this device is completed for the laying of broadcast and television coverage cables, after the fixed frame 101 is fixed in the required position with bolts and other fasteners, the lifting frame 103 can be moved up and down relative to the fixed frame 101. After the height of the lifting frame 103 meets the height requirements of the cable laying, the fixed frame 101 and the lifting frame 103 are connected by the connecting bolt 104. Then the cable can be introduced into and out of this device.

[0038] When introducing the cable, the cable should be led from above each of the lower clamping wheels 207 to the rotating rod 210. If the cable needs to change its direction when it is led out of this device, it can be led out while it is in contact with the rotating rod 210 so that the bending range of the cable can be limited by the rotating rod 210.

[0039] After the cable has made contact with the rotating rod 210 and each of the lower clamping wheels 207, the bidirectional screw 302 can be rotated by the second knob 303 to make the first carrier 201 and the second carrier 202 move away from each other. During this process, the connecting rod 205 will pull the two slides 204 to move towards each other. Simultaneously, the higher clamping wheel 207 will move towards the lower clamping wheel 207 and cooperate with it to clamp the cable.

[0040] Once the cable is fully pulled and arranged without needing to be moved, the height difference between the two sets of clamping wheels 207 with different heights can be readjusted by rotating the second knob 303, so that the clamping wheels 207 can clamp the cable, thereby fully securing the cable. When maintenance or cable replacement is required, simply rotate the second knob 303 to move the first carrier 201 and the second carrier 202 a certain distance towards each other, which can quickly separate the cable from the clamping wheels 207 and the rotating rod 210, after which the cable can be removed from the device.

[0041] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
