[0051] The application will be described in detail below in combination with the drawings and specific embodiments.

[0052] The embodiment provides a cable pay-off device, as shown in the drawings, which comprises: Figures 1-3

[0053] ​Support unit 10, for supporting and fixing the cable reel 30, is configured with a set of oppositely arranged bases 11; on the upper end surface of each base 11 is provided with a groove 12 for placing the cable reel 30 disc surface; in the groove 12 of each base 11 is provided with an adjusting assembly 14 for adjusting the height of the cable reel 30, controlling the two adjusting assemblies 14 on both sides of the base 11, which can be adjusted synchronously to adjust the position height for supporting the cable reel 30 disc surface.

[0054] Fixed unit 20, for fixing the support unit 10 and clamping the central axis of the cable reel 30, is configured with a connecting assembly 21 for adjusting the horizontal distance between the bases 11 and connecting all the bases 11 together, and a clamping assembly 22 for clamping the cable reel 30, the clamping assembly 22 is detachably connected with the connecting assembly 21.

[0055] Among them, the connecting assembly 21 is placed at the tail end of the base 11, and the adjusting assembly 14 is arranged close to the front end of the base 11. When using, when the cable reel 30 rolls to the front end of the base 11, the position height for supporting the cable reel 30 is adjusted by the adjusting assembly 14, so that the support point is located at the lowest position; then the bottom of the cable reel 30 is lifted off the ground, and the two adjusting assemblies 14 are adjusted to the same degree, so that the cable reel 30 does not move or fall due to the weight of the cable itself. When using, according to the spacing between the disc surfaces of the cable reel 30, the spacing between the two bases 11 is adjusted by the connecting assembly 21, so that the cable reel 30 can be smoothly rolled into the groove 12 on the base 11. When the cable reel 30 is not working, the connecting assembly 21 can be pushed to quickly move the two rollers at the tail end of the base 11.

[0056] The front end of the base 11 is configured as a downwardly inclined slope, the slope 11 and the horizontal angle θ is an acute angle, preferably, the angle θ is 60°, which is beneficial to the cable reel 30 rolling into the base 11. In this embodiment, the base 11 can be made of 20# channel steel and 10mm thick steel plate by welding, and the slope at the front end can be made by welding the steel plate.

[0057] Rollers are provided at the tail end of the base 11, the axis of the roller is perpendicular to the length direction of the base 11, and the radius of the roller is greater than the height from the connecting point of the roller to the lower end surface of the base 11, so that the fixed unit 20 can be pushed to move the two bases 11 by the rollers; the rollers are used to support the movement of the entire cable laying device.

[0058] The groove 12 is arranged near the front end of the base 11, and is arranged through the height of the base 11, that is, the thickness, and is a through-hole structure of a cuboid. A plurality of long holes 13 are also arranged on the two side walls of the base 11 and communicate with the groove 11. The long holes 13 are symmetrically arranged along the lengthwise center line of the base 11. That is, two sets of symmetrically arranged long holes 13 are arranged on each base 11, and the positions of the long holes 13 on the two bases 11 are in one-to-one correspondence. The long holes 13 are mainly used to adjust the rolling distance of the movable pulleys 141 in the adjusting assembly 14.

[0059] Further, the adjusting assembly 14 includes movable pulleys 141 arranged at both ends of the groove 12, a chain 142 connecting the movable pulleys 141, and a wheel disc 143 fixed to the outer wall surface of the groove 12, the wheel disc 143 being a hand wheel disc. The shaft of the movable pulley 141 penetrates the long hole 13 and protrudes from the outer wall surface of the groove 12. The wheel disc 143 is arranged between the two movable pulleys 141, and the chain 142 connects the wheel disc 143 with the two movable pulleys 141. The movable pulley 141 is the main load-bearing and rotating component of the cable reel 30, and is used to support the bottom disc surface of the cable reel 30 and drive the disc surface of the cable reel 30 to roll. The outer end of the central shaft is provided with a circular hole through which the chain 142 passes. The chain 142 is a steel cable, and is used to connect the outer end of the central shaft of the two movable pulleys 141 with the middle hand wheel disc 143. The distance between the two movable pulleys 141 is adjusted by the hand wheel disc 143.

[0060] The length of the chain 142 between the two movable pulleys 141 is adjusted by controlling the wheel disc 143, so as to reduce the distance between the two movable pulleys 141, thereby reducing the arc surface of the contact point between the movable pulley 141 and the disc surface of the cable reel 30, and thereby increasing the height of the center of gravity of the disc surface of the cable reel 30, and further increasing the height of the position at which the cable reel 30 is supported by the movable pulley 141. When the center of gravity of the falling cable reel 30 is lowered, the length of the chain 142 is increased by rotating the wheel disc 141, so as to increase the distance between the two movable pulleys 141, and thereby increase the arc surface of the contact point between the movable pulley 141 and the disc surface of the cable reel 30, and thereby lower the position of the center of gravity of the disc surface of the cable reel 30.

[0061] In the fixing unit 20, the connecting assembly 21 includes a frame body 211, a rotating disc 212, a flexible member 213, and a handle 214. Among them,

[0062] The frame 211 is configured with several base frames, top frames, vertical frames, and diagonal frames, forming a triangular support frame. The base frames, top frames, vertical frames, and diagonal frames are all welded from Φ89mm seamless steel pipes. There is only one top frame, arranged horizontally, which also serves as a push handle. There are two base frames, arranged parallel to the top frames, extending through the wall thickness of the two bases 11. There are three vertical frames and five diagonal frames, mainly used to connect the top frames and base frames, welding all the steel pipes together to form the frame 211. The base frames are arranged perpendicular to the length of the bases 11 and connect to the vertical frames and diagonal frames respectively, passing through the bases 11. One end of each vertical frame is connected to the top frame, and the other end is connected to the base frame near the tail end of the base 11; and the lower end of one vertical frame is connected to the middle position of the base frame near the tail end of the base 11. One end of each of the inclined frames is connected to the top frame, and the other end is connected to the base frame on the side away from the tail end of the base 11; and the lower ends of three of the inclined frames are connected to the middle position of the base frame on the side away from the tail end of the base 11.

[0063] The turntable 212, used to adjust the distance between the two bases 11, is located on the lower end face of the frame 211, with its axis perpendicular to the length of the base 211, and is positioned in the middle of the two bases 11. The turntable 212 is located in the middle of the length of the base, with its two axial ends connected to the base; the handle 214 is located on the base near the tail end of the base 11 and protrudes outward.

[0064] The flexible component 213 is a steel cable used to connect the two bases 11 and the turntable 212. The flexible component 213 is wound around the axis of the turntable 212, passes through the wall thickness of the two bases 11, and then reconnects to the turntable 212.

[0065] The handle 214 is welded and fixed to the outermost base frame and connected to the turntable 212. It is also connected to the axis of the turntable 212 in a staggered manner, which makes it easy to operate the handle 214 to rotate the turntable 212.

[0066] Rotating handle 214 controls the turntable 212 to rotate, thereby adjusting the base 11 to move in opposite directions along the length of the base frame via flexible member 213, in order to control the horizontal distance between the two bases 11.

[0067] Based on the distance between the two sides of the cable reel 30, the turntable 212 is rotated using the handle 214 to adjust the distance between the two bases 11 via the flexible member 213, allowing the cable reel 30 to smoothly roll into the groove 12 on the base 11. When the cable reel 30 is not in operation, the top frame, which serves as a handle, can be pushed to control the roller at the tail of the base 11 for rapid movement.

[0068] Further, the lock assembly 22 includes a lock lever 221 and a lock rope 222 arranged at both ends of the lock lever 221, and the other end of each lock rope 222 is connected to the upper segment of the outermost 2 inclined racks corresponding to the position of the end thereof. That is, the inclined racks of the rack body 211 are provided with the hanging holes of the lock rope 222 for protection, and the bottom frame of the rack body 211 is provided with two fixing shafts for fixing the main body of the base 11. Among them, the lock lever 221 is a seamless steel pipe, and the pipe diameter is selected according to the size of the middle hole of the cable reel 30. The lock rope 222 is a safety steel cable, which can connect the shaft of the cable reel 30 with the inclined rack through the lock lever 221, so as to prevent the cable reel 30 from tilting forward or rolling out of the base 11 due to external force.
