Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a movable pay-off machine for laying cable lines. Background Art

[0002] A cable is a power transmission line consisting of one or more insulated conductors, an insulating layer, a sheath and an outer insulating layer. It is used to transmit electrical energy from one place to another. When laying cables underground, factors such as the soil conditions, depth, and protective measures must be considered. It is usually done by digging trenches, crossing pipes, or using buried cable troughs.

[0003] At present, it is usually necessary to manually drag cables for laying. When dealing with longer cables, due to the weight and length limitations of the cables, the manual dragging operation not only consumes a lot of manpower and physical strength, causing a certain waste of labor resources, but also the cables are easily rubbed against the ground during the manual dragging process, causing wear and tear, accelerating cable damage, thereby increasing maintenance costs. Utility Model Content

[0004] The utility model aims to provide a movable pay-off machine for laying cable lines which does not require manual cable dragging, reduces labor and avoids cable wear.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A movable pay-off machine for laying cable lines comprises a bottom plate, a pay-off groove is provided on the surface of the bottom plate, a vertical plate is installed on one side of the upper surface of the bottom plate, a pay-off drum is rotatably installed on the outer surface of the vertical plate, an inner groove is provided inside the pay-off drum, a plurality of notches are provided on the surface of the inner groove, and the notches are connected to the inner groove, a wedge-shaped abutment block is provided inside the notch, a movable rod is installed inside the inner groove through a moving mechanism, a plurality of truncated cone-shaped extrusion blocks are installed on the outer surface of the movable rod, and the inclined surface of the truncated cone-shaped extrusion block faces the inclined surface of the bottom of the wedge-shaped abutment block. A driven shaft is rotatably installed on one side of the bottom of the bottom plate, a driving shaft is rotatably installed on the other side of the bottom of the bottom plate through a driving mechanism, and moving wheels are installed at both ends of the driven shaft and the driving shaft in the length direction. A connecting shaft is rotatably connected to the outer surface of the other side of the vertical plate, and the connecting shaft is connected to the pay-off drum, and pulleys are installed on the end of the connecting shaft and the outer surface of the moving wheel at one end of the driving shaft, and a transmission belt is meshed between the two pulleys.

[0007] It can be seen that the cable reel is put on the pay-off drum, and the moving mechanism is used to drive the wedge-shaped abutment block to press against the inner wall of the cable reel sleeve to fix the cable reel. Then the driving mechanism drives the moving wheel to rotate and drives the base plate to move. During the movement of the base plate, the pay-off drum can be driven to rotate through the transmission action of the transmission belt, and the cable reel can be driven to automatically pay out the wire, so that the cable can be laid in the groove during walking, thereby completing the purpose of automatic pay-off, avoiding the problems of manual dragging and cable wear, and having high practicality.

[0008] Furthermore, the moving mechanism includes a threaded hole opened at one end of the movable rod, a threaded rod is installed inside the threaded hole, the end of the threaded rod passes through the outside of the wire reel and is installed with a handwheel, and a telescopic rod A is installed at the other end of the movable rod, and the end of the telescopic rod A is connected to the inner wall of the inner groove.

[0009] When the cable reel is put on the pay-off drum, the hand wheel can be turned to drive the threaded rod to rotate. Since the movable rod is limited by the telescopic rod A, it can move while the threaded rod rotates, and drive the truncated cone-shaped extrusion block to squeeze the wedge-shaped abutment block. The extrusion drives the wedge-shaped abutment block to extend outward and press against the inner wall of the cable reel sleeve to complete the fixation.

[0010] Furthermore, the driving mechanism includes a motor installed on the upper surface of the base plate, the end of the motor output shaft passes through the lower side of the base plate and is installed with a bevel gear A, the outer surface of the driving shaft is installed with a bevel gear B, and the bevel gear B is meshed and connected with the bevel gear A.

[0011] When the motor is started, its output shaft drives bevel gear A to rotate. Since bevel gear A and bevel gear B are meshed with each other, the driving shaft can be driven to rotate, and the moving wheels at both ends can be driven to rotate, so that the bottom plate can move forward.

[0012] Furthermore, a side block is installed on the outer surface of the wedge-shaped abutment block, a telescopic rod B is installed on the upper surface of the side block, the end of the telescopic rod B is connected to the inner wall of the inner groove, and a spring is sleeved on the outer surface of the telescopic rod B, and the two ends of the spring are respectively abutted against the side block and the inner wall of the inner groove.

[0013] When the wedge-shaped abutment block is squeezed by the truncated cone-shaped squeezing block and moves outward, the wedge-shaped abutment block drives the side block to compress the spring. When the threaded rod is rotated in the opposite direction to drive the movable rod to move in the opposite direction, the compressed spring releases the elastic force to push the wedge-shaped abutment block to reset downward.

[0014] Furthermore, an armrest is installed on the upper surface of the base plate, and an anti-slip rubber pad is provided on the outer surface of the armrest.

[0015] By setting the handrail, the direction of the base plate can be controlled during its movement.

[0016] Furthermore, the number of each group of slots is four, and the four slots are distributed in a coaxial array.

[0017] By setting the four notches, the four wedge-shaped abutting blocks can be respectively pressed against the inner walls on the four sides of the cable drum sleeve, so that the force is more uniform, thereby ensuring the fixing effect of the cable drum. BRIEF DESCRIPTION OF THE DRAWINGS

A pulley 113 is mounted on the end of the connecting shaft 112 and the outer surface of the moving wheel 111 at one end of the driving shaft 110, and a transmission belt 114 is meshed between the two pulleys 113.

[0025] When in use, the cable reel is first put on the wire-paying drum 103, and then the movable rod 107 is driven to move by the moving mechanism 200, driving the truncated cone-shaped extrusion block 108 to squeeze the wedge-shaped abutment block 106, and the wedge-shaped abutment block 106 is driven to move outward and press against the inner wall of the cable reel sleeve by extrusion, so as to achieve the purpose of fixing the cable reel. The wedge-shaped abutment block 106 can be set to two, three, four or other groups, all of which can achieve the purpose of fixing the cable reel.
