[0006] Another example is the Chinese utility model patent "A cable laying device" with authorization announcement number CN209805260U, which includes a support plate, a roller is arranged at the bottom of the support plate, a hand push frame is installed on the left side of the front and rear ends of the support plate, a fixed seat is fixedly installed at the front end of the left top of the support plate, the rear end of the rotating shaft passes through the column and is fixedly connected to the output end of the servo motor, the servo motor is installed on the top of the support plate, a rectangular hole is opened on the front side of the column, a sliding rod is vertically arranged in the rectangular hole, a movable block is sleeved on the outer wall of the sliding rod, a compression spring is sleeved on the outer wall of the sliding rod and is located between the movable block and the top of the rectangular hole, a conveying roller 2 matching the conveying roller 1 is arranged on the front side of the movable block through the rotating rod, and a wire wheel is arranged on the right side of the top of the support plate through the rotating shaft seat. The device is convenient and quick for laying cables, can reduce the labor intensity of construction personnel, and improve laying efficiency.

DETAILED DESCRIPTION
[0026] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.
[0027] like Figure 1 , Figure 2 , Figure 3 , pictures and Figure 5 As shown, the present invention provides a hand-pushed mobile transport vehicle for cable laying, including a trolley body, which is mainly composed of a chassis 1, casters 4 and handrails 9. Four casters 4 are fixedly installed at the four corners of the lower end of the chassis 1, and the casters 4 do not have brakes.
[0028] It also includes a cable turntable 20, which is generally composed of a winding drum and circular baffles located at both ends of the winding drum. The winding drum is used for winding the cable, and the center of the circular baffle is provided with a connection hole for providing external docking.
[0029] A supporting floor 2 which can be raised and lowered is provided at the lower end of the chassis 1, and the lower end of the supporting floor 2 has an anti-slip structure.
[0030] A sleeve 3 with an inner diameter slightly larger than the horizontal dimension of the caster 4 is provided at the upper end of the support floor 2 corresponding to the position of the four casters 4. The sleeve 3 is shorter than the caster 4 in the vertical direction, and the difference between the two is used to realize the up and down lifting function of the support floor 2.
[0031] The upper end of the chassis 1 is located in the vertical direction of the armrest 9 and is provided with two symmetrical arc-shaped limit grooves 18. The bottoms of the two arc-shaped limit grooves 18 match the cable turntable 20, that is, the bottoms of the arc-shaped limit grooves 18 match the baffle edge of the cable turntable 20 to provide a good limiting effect for the baffle.
[0032] The upper end of the chassis 1 is located on the outside of the two arc-shaped limit grooves 18 and is provided with two symmetrical inner support plates 17. A rotating rod 24 for docking the cable turntable is independently provided above the inner support plate 17, that is, there is no connection between the rotating rod 24 and the inner support plate 17. After the rotating rod 24 is docked with the connecting hole in the center of the circular baffle of the cable turntable 20 through a fastening plate, fasteners, etc., the rotating rod 24 is located above the inner support plate 17, so that the cable turntable 20 rolls from the front of the chassis 1 to the chassis 1 and is limited in the two arc-shaped limit grooves 18 when in use.
[0033] Two symmetrical driven gears 22 are correspondingly provided on the two rotating rods 24 on the outer sides of the two inner support plates 17, and a U-shaped fork 25 that can move up and down is provided on the upper outer side of the inner support plate 17. When the two U-shaped forks 25 move up and down, they can support the two connected rotating rods 24 to move up and down, thereby supporting the cable turntable 20 to move up and down, corresponding to the two working states of the cable turntable 20 being rotatable and non-rotatable.
[0034] Two symmetrical outer support plates 15 are provided on the outer sides of the two inner support plates 17. The outer support plates 15 are arranged higher than the inner support plates 17. The upper part of the outer support plates 17 is located directly above the driven gear 22 and is provided with a driving gear 21 that matches the driven gear 22. That is, the driving gear 21 and the driven gear 22 can be meshed with each other when in use. After the driven gear 22 follows the rotating rod 24 and moves upward into position, it can mesh with the driving gear 21 for power transmission. That is, after mutual meshing, the driving gear 21 can drive the driven gear 22 to rotate, thereby driving the rotating rod 24 to rotate, and then driving the cable turntable 20 to rotate.
[0035] A horizontally rotatable rubber roller 27 is provided on the upper part of the handrail 9 for raising the cable, which is convenient for pulling the cable out from the upper end. At this time, the cable is in a tensioned state, which effectively avoids the loosening of the cable and prevents the friction between the cable, the device and the ground, causing mechanical loss of the cable skin. A limiting groove 271 is provided in the center of the rotatable rubber roller 27 for limiting the rolling range of the cable on the rubber roller to prevent the cable from shaking at will, which is conducive to the smooth completion of the cable laying work.
[0036] Specifically, it also includes a controller A10 arranged on the armrest 9 and four electric push rods A8 symmetrically installed on the upper end of the chassis 1 and located directly above the sleeve tube 3. The working axis of the electric push rod A8 passes downward through the chassis 1 and is connected to the sleeve tube 3. The support floor 2 can be synchronously lifted up and down by the drive of the four electric push rods A8 under the control of the controller A10. Through the synchronous drive, the support floor 2 can be stably and reliably lifted up and down. The lower end of the support floor 2 is arranged to have an anti-slip structure to increase the friction between it and the ground, so that the entire device is more stable and reliable during the cable laying process.
[0037] Specifically, the electric push rod A8 is elevated by a support frame 7 and installed on the chassis 1. The working shaft of the electric push rod A8 is connected to a push plate 6. A plurality of push rods 5 that are evenly and symmetrically distributed are provided at the lower end of the push plate 6. The lower ends of the plurality of push rods 5 pass through the chassis 1 and are commonly connected to the sleeve tube 3. The push plate 6 and the plurality of push rods 5 together evenly transmit the driving power of the electric push rod A8 to the sleeve tube 3.
[0038] Specifically, it also includes a controller B11 arranged on the armrest 9 and two electric push rods B26 symmetrically installed on the outer sides of the two inner support plates 17. The working ends of the electric push rods B26 are connected upward with U-shaped forks 25. The two U-shaped forks 25 can be driven up and down synchronously by the two electric push rods B26 under the control of the controller B11, so as to stably and reliably support and lower the cable turntable 20.
[0039] Specifically, a bearing 23 is provided on the rotating rod 24 at a position where the U-shaped fork 25 supports it, and the bottom of the U-shaped fork 25 is matched with the bearing 23. Through the bearing 23, the cable rotary drum 20 can rotate easily and flexibly.
[0040] Specifically, a hemispherical block 231 is provided on the outer side of the bearing 23, and a hemispherical groove 251 matching the hemispherical block 231 is provided on the bottom of the U-shaped fork 25. The bearing 23 can be clamped into the hemispherical groove 251 through the hemispherical block 231 and then clamped at the bottom of the U-shaped fork 25. The hemispherical block 231 and the hemispherical groove 251 can make the U-shaped fork 25 support the bearing 23 (i.e., the rotating rod 24) more stably and reliably.
[0041] Specifically, it also includes a controller C12 arranged on the handrail 9 and two rotating motors 16 symmetrically installed on the outside of the two outer support plates 15. The working shaft of the rotating motor 16 passes through the outer support plate 15 and is connected to a driving gear 21. The two driving gears 21 can synchronously drive two driven gears 22 to rotate forward and reverse through the two rotating motors 16 under the control of the controller C12 (the forward and reverse rotations correspond to the pulling out and retracting of the cable during the laying work, wherein the retraction is to rewind the pulled out excess cable back onto the winding drum of the cable turntable 20) to complete the power transmission.
[0042] During specific implementation, the controller A10, the controller B11 and the controller C12 may be integrated together.
[0043] Specifically, two symmetrical hinges 14 are hingedly connected on both sides of the upper part of the outer support plate 17, and the outer ends of the hinges 14 are connected to a U-shaped slot 13 matched with the cable turntable 20. A butterfly bolt is provided on one side of the U-shaped slot 13. By tightening the butterfly bolt, the baffle edge of the cable turntable 20 can be temporarily fixed in the U-shaped slot 13. At the same time, by tightening the hinge 14, the cable turntable 20 is temporarily limited, which is used to facilitate the cable turntable 20 to move with the trolley when necessary; when temporary limitation is not required, the U-shaped slot can be temporarily limited on the outer support plate 15 to prevent it from swinging at will.
[0044] Specifically, the bottom of the U-shaped slot 13 matches the cable turntable 20, and the temporary limiting effect is better.
[0045] Specifically, a buffer auxiliary slope 19 that rises from the outside to the inside is provided on the chassis 1 in close contact with the outer sides of the two arc-shaped limit grooves 18. The inner ends of the buffer auxiliary slopes 19 are at the same height and smoothly transition to the bottoms of the two arc-shaped limit grooves 18. The buffer auxiliary slopes 19 are provided to facilitate the cable turntable 20 to roll from the front of the chassis 1 into the arc-shaped limit grooves 18 in a time-saving and labor-saving manner.
[0046] When the present invention is actually used, the device is first moved to the cable transport vehicle, and four electric push rods A are synchronously started to lower the support floor 2 until the device stops moving. A diagonal support plate is obliquely placed in front of the chassis 1 between the upper end of the chassis 1 and the ground. The diagonal support plate is used to facilitate the rolling of the cable turntable 20. The cable turntable 20 is rolled from the transport vehicle to the vicinity of the device, and then rolled onto the chassis 1 along the diagonal support plate and the buffer auxiliary slope 19, and limited in the arc-shaped limit groove 18, and then the device moves to the working position and stops; two electric push rods B26 are synchronously started to make the two U-shaped forks 25 rise synchronously, respectively lift up the two bearings 23, and continue to rise until the two driven gears 22 and the two driving gears 21 are respectively meshed with each other, and then the two rotating motors 16 are synchronously started to make the two driving gears 21 rotate synchronously, drive the two driven gears 22 to rotate synchronously, drive the two rotating rods 24 to rotate synchronously, drive the cable turntable 20 to rotate, start to release the cable, and after the cable release work is completed, collect it until the collection work is completed. At this time, the cable laying work at the working position is completed.
[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the specific implementation modes of the present invention can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
