Description

Technical Field

[0001] The invention relates to the technical field of transport equipment, in particular to a device for quickly paying out lines of vertical and horizontal transport equipment. Background Art

[0002] Transportation equipment is the tools and devices used to move and transport people or various types of goods. It plays an extremely critical role in all areas of production and life in modern society.

[0003] Functionally, it can be divided into vertical transportation equipment and horizontal transportation equipment. Vertical transportation equipment, such as elevators, can quickly and safely transport people and small goods between different floors in a building, greatly improving the convenience of vertical travel; there are also tower cranes on construction sites that can lift building materials to high work surfaces. There are many types of horizontal transportation equipment. Cars can transport large amounts of goods or carry passengers over long distances on the road; conveyor belts in factories can accurately transfer parts and components horizontally between different production links, promoting the smooth operation of the production process. These transportation equipment cooperate with each other to build a complex and efficient modern transportation system.

[0004] In the prior art, people often use cranes to vertically lift and horizontally move goods within a certain range, thereby satisfying heavy object transportation operations in both the horizontal and vertical planes.

[0005] However, in actual use, the winding roller often needs to maintain a high speed during the process of reeling and unreeling the cable in order to meet the high-speed release and retraction of the cable. However, during the high-speed retraction of the cable, there is a risk of the cables being entangled with each other, which affects the smoothness of the subsequent pay-off process and also makes the pulley at the boom at risk of getting stuck. In view of this, we propose a device for quickly paying out the cable for vertical and horizontal transport equipment. Summary of the invention

[0017] Preferably, the air bin is provided with a plurality of through holes on one side close to the wire management block slot, the nozzle is overall arranged to be tilted downward, and a through groove connected to the air nozzle is provided on the upper surface of the wire management block.

[0018] Working principle: When using this device, it is necessary to start the motor according to the specific material transportation needs to drive the pay-off roller to rotate, and release the cable so that the hook can drop as a whole and contact the material waiting to be transported. At the same time, after the material is fixed, it is necessary to start the motor to reverse and start the rotating base to drive the material to be transported vertically or horizontally. At the same time, during the rotation of the pay-off roller, the reciprocating screw will be driven to rotate through the transmission adjustment device. During the rotation of the reciprocating screw, the wire management block on its outer side will be driven to continuously reciprocate on its surface, and the retracted cables will be guided through the through hole at its end, so as to ensure that the cables can be evenly distributed on the surface of the pay-off roller during the process of paying off or taking up, thereby reducing the cables from being interlaced with each other. There is a risk of entanglement. At the same time, according to the different cable diameters used and the number of winding coils, the movable end of the hydraulic cylinder can be controlled to extend or retract by electronic control, so that the transmission belt on the surface of the driven roller can be switched during the movement of the transmission wheel one and the transmission wheel two. When the transmission belt moves to the outer surface of the transmission wheel one, since its own diameter is smaller than the transmission wheel two, the auxiliary wheel will synchronously contact the transmission belt to form a shape similar to a triangle, keeping the tension of the transmission belt stable. After the switching is completed, the transmission ratio between the pay-off roller and the reciprocating screw will also change accordingly, so as to adapt to different pay-off conditions and keep the pay-off process in a line-sorting state, thereby ensuring high efficiency during the pay-off process.

[0019] In addition, since the outer surface of the cable is often directly exposed to the external environment during use, there is a risk of dust and impurities sticking to its outer surface. Therefore, a cleaning plate can be inserted into the internal slot of the cable management block, and the cleaning plate can be positioned through the adsorption between the magnetic block at the top and the cable management block and the friction between the cable management block and the cleaning plate. At this time, the bristles on the surface of the cleaning plate will always be in contact with the surface of the cable during the movement of the cable, thereby cleaning the floating dust and impurities on its surface. At the same time, a high-pressure air supply device can be connected through the air nozzle on the surface of the cable management block, and high-pressure air can be supplied during the process of retracting and releasing the cable so that the air can enter the air chamber through the air nozzle and be sprayed out through the nozzle. At this time, the inclined nozzle will assist the cleaning plate in cleaning the cable surface by spraying high-pressure air, thereby avoiding the normal retracting and releasing process being affected by impurities sticking to the cable surface.

[0020] The present invention provides a device for quickly releasing wires from vertical and horizontal transport equipment. It has the following beneficial effects:

[0021] 1. The present invention can synchronously drive the reciprocating screw to rotate during the rotation of the pay-off roller by means of the motor, pay-off roller, wire management block, reciprocating screw, support rod, support frame and connecting seat, and can drive the wire management block to continuously reciprocate through the rotation of the reciprocating screw, thereby ensuring that the cables are neatly arranged during the pay-off and retracting process, avoiding abnormal pay-off of the cables due to the intertwining and entanglement of the cables, and enabling the pay-off to be performed stably and quickly.

[0022] 2. The present invention, through the arranged driven wheel, auxiliary roller, transmission wheel 2, transmission wheel 1, hydraulic cylinder and connecting rod, can adjust the transmission ratio between the pay-off roller and the reciprocating screw rod when using cables of different diameters and cables with different numbers of turns wound around the surface of the pay-off roller, and by changing the transmission ratio, the wire management process can always meet the demand of high-speed pay-off.

[0023] 3. The present invention can clean the cable surface during the process of paying out and taking up the cable by means of the air nozzle, cleaning plate, magnetic block, nozzle and air chamber, thereby avoiding entanglement and adhesion between cables caused by impurities and dust adhering to the cable surface, thereby enabling the device to always stably perform high-speed paying-out operations during the vertical and horizontal transportation of materials.
