Description

Technical Field

[0001] The present invention relates to a cable wire pay - out device and a using method, belonging to the technical field of cable wires. Background Art

[0002] Cable wire pay - out mainly relies on devices such as wire pay - out racks, cable lifting, and cable transportation. Through the coordinated use of these devices, the stable pay - out of large - scale cable wires can be achieved, and the labor intensity of workers can be greatly reduced. The operation of the device only requires 1 - 2 people to complete.

[0003] Generally, for lifting, a bracket and pulley structure are used, which can greatly reduce the force of pulling the lifting rope. However, the existing cable lifting devices used in cable wire pay - out have poor stability. When used on construction sites, they are mostly used on muddy ground, and the problem of bracket inclination is likely to occur. The free end of the driving device is connected to the lifting rope. If the driving motor fails, safety accidents will occur. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, and a cable wire pay - out device and a using method are proposed.

[0005] To achieve the above - mentioned purpose, the present invention adopts the following technical scheme: A cable wire pay - out device includes a bracket structure. A fixed pulley structure is arranged at the top of the bracket structure. The fixed pulley structure is connected to a movable pulley assembly through a lifting rope, and a hook is arranged at the bottom end of the movable pulley assembly.

[0006] The side of the bracket structure is fixedly connected to a power structure through a holding rod. The movable end of the lifting rope is connected to the power structure. An emergency wire - locking structure is also arranged on one side of the power structure, and the lifting rope passes through the emergency wire - locking structure.

[0007] As a further description of the above - mentioned technical scheme:

[0008] The bracket structure is composed of three support rods. The tops of the three support rods are connected together and the bottoms are dispersed.

[0009] As a further description of the above - mentioned technical scheme:

[0010] The support rod includes a main rod body. A detachable base is arranged at the bottom end of the main rod body. A ground - clamping foot is arranged at the bottom end of the detachable base, and a handle is fixedly connected to the side of the detachable base.

[0011] As a further description of the above - mentioned technical scheme:

[0012] The fixed pulley structure includes a pulley mounting bracket, with a pulley body movably connected to the inner side of the pulley mounting bracket. A guard rod is fixedly connected to the inner side of the pulley mounting bracket and above the pulley body. An ear plate is provided on the outer side of the pulley mounting bracket.

[0013] As a further description of the above technical solution:

[0014] The multiple support rods include a main support rod and two sub-support rods. The top end of the main support rod is connected to the pulley mounting bracket, and the top ends of the two sub-support rods are connected to a connecting frame. The connecting frame is movably connected to the ear plate through a pin.

[0015] As a further description of the above technical solution:

[0016] The emergency wire locking structure includes a wire locking body. A wire guiding channel is formed on the side of the wire locking body. A locking member mounting channel perpendicular to the wire guiding channel is also formed on the side of the wire locking body. A spring is arranged inside the locking member mounting channel. An arc-shaped block is arranged inside the locking member mounting channel and on the right side of the spring. A frame-shaped frame is fixedly connected to the side of the arc-shaped block. A locking block is fixedly connected to the inner side of the locking member mounting channel and on the right side of the wire guiding channel. A self-locking plate is arranged inside the locking member mounting channel and on the right side of the locking block.

[0017] As a further description of the above technical solution:

[0018] The suspension rope is made of steel wire rope and is located inside the wire guiding channel.

[0019] As a further description of the above technical solution:

[0020] Tooth teeth are provided on the side of the locking block close to the wire guiding channel.

[0021] A method for using a cable wire paying-off device, the method comprising the following steps:

[0022] S01. Push the arc-shaped block towards the spring side, so that the right side surface of the arc-shaped block is located on the left side of the wire guiding channel, the column in the middle of the frame-shaped frame is located on the left side of the self-locking plate, and the column in the middle of the frame-shaped frame is located on the right side of the wire guiding channel;

[0023] S02. Pass the free end of the suspension rope through the wire guiding channel and connect it to the power mechanism;

[0024] S03. Use a hook to pick up the cable reel, and then contract the free end of the suspension rope through the power structure to lift the cable reel until it is lifted off the ground.

[0025] The present invention has the following beneficial effects:

[0026] 1) Compared with the prior art, for this cable wire pay-off device, by setting an emergency wire locking structure, once the power structure fails to work, the emergency wire locking structure can respond quickly to lock the lifting rope and avoid safety accidents.

[0027] Compared with some locking structures on the market (including monitoring systems and power actuators), it has a more sensitive response, better braking effect, does not require monitoring and power components, and has a lower mechanical failure rate.

[0028] 2) By setting three groups of support rod structures, a three-dimensional tetrahedral structure is formed with the ground, making the structure more stable.

[0029] 3) For this cable wire pay-off device, by setting a support structure, the fixed pulley structure is installed at the top of the support structure, the driving device is installed on the side of the support structure, and the movable pulley assembly naturally pulls the lifting rope downward, making the movable pulley assembly located at the central position. The overall structure is relatively stable, and a detachable base and a ground anchor structure are provided, enabling it to work on muddy ground and having stronger working performance.

[0030] 4) The pulley structure reduces the driving force of the motor, so that under the same driving force, the maximum lifting load becomes larger.

[0031] 5) The two groups of sub-support rods and the main support rod are movably connected through an ear plate and pin connection structure. When not in use, the three support rods can be conveniently retracted, making it very convenient for carrying and transportation.

[0032] 6) In the emergency wire locking structure, the locking block and the spring structure always press against the side of the lifting rope. When the device is running normally, the lifting rope is in a tensioned state and the locking block does not play a role. Once the lifting rope becomes slack, the locking block is pushed out under the action of the spring, clamping the lifting rope inside the locking block. At the same time, the frame-shaped frame and the self-locking plate form a self-lock, achieving a firm lock and being very safe to use.

[0033] 7) Using steel wire ropes is cheaper, wear-resistant, has a relatively large surface friction, is easy for the emergency wire locking structure to take effect, and increases the service life.

[0034] 8) The tooth structure set on the locking block can increase the wire locking effect and prevent the lifting rope from still sliding after the device is triggered. BRIEF DESCRIPTION OF THE DRAWINGS
