Description

Technical Field

[0001] This utility model relates to the field of cable handling technology, and in particular to a cable transport vehicle that moves laterally. Background Technology

[0002] In existing technologies, cable transport vehicles typically use steering wheels to achieve multi-angle rotation for directional movement. However, steering wheels require high precision and are expensive. In cable transport scenarios, actual operations prioritize translational movement. Some existing cable transport vehicles achieve translation through the coordinated use of multiple steering wheels. Therefore, designing a simple, low-cost, and reliable transport device that satisfies the translational function of cable transport has become a key technical problem. Utility Model Content

[0003] To solve the problem of lateral movement of cable transport vehicles, this utility model provides a cable transport vehicle that can move laterally.

[0004] This utility model provides a laterally moving cable transport vehicle, including a central control vehicle body. The front end of the central control vehicle body is provided with a vertically erected support frame. A fork assembly is provided on the lower side of the support frame. The fork assembly includes a main base frame and an auxiliary base frame stacked on the lower side of the main base frame. The main base frame has a longitudinal traveling mechanism at the ground contact end, and the auxiliary base frame has a lateral traveling mechanism at the ground contact end. A drive assembly is provided on the support frame. The drive assembly can drive the auxiliary base frame to move towards the ground so that the lateral traveling mechanism touches the ground and the longitudinal traveling mechanism moves away from the ground.

[0005] Furthermore, the drive assembly includes a telescopic device 1 disposed on the support frame, the auxiliary base frame having an auxiliary limiting back plate, the auxiliary limiting back plate being slidably connected to the support frame, and the power output shaft of the telescopic device 1 being connected to the auxiliary limiting back plate to drive the auxiliary base frame to move toward the ground so that the lateral travel mechanism touches the ground.

[0006] Furthermore, drive sliders are fixedly provided on both sides of the auxiliary limiting back plate, and drive guide rails that cooperate with the drive sliders are provided on the support frame, with the drive sliders slidably connected to the drive guide rails.

[0007] Furthermore, a drive connecting block is provided on the auxiliary limiting back plate, the power output shaft of the telescopic device is connected to the drive connecting block, a guide rod is provided on the support frame, and the drive connecting block is sleeved on the guide rod and slidably connected to the guide rod.

[0008] Furthermore, the main base frame has a main limiting back plate, the guide rod is fixedly connected to the main limiting back plate, and limiting sliders are fixedly provided on both sides of the main limiting back plate, and the limiting sliders are fixedly mounted on the drive guide rail.

[0009] Furthermore, the longitudinal travel mechanism includes a pair of longitudinal travel wheels, which are respectively disposed at the bottom ends of the two forks of the main chassis. The lateral travel mechanism includes two pairs of lateral travel wheels, which are respectively disposed at the bottom ends of the two forks of the auxiliary chassis. The lower end of the central control vehicle body is provided with a pair of longitudinal drive wheels, which are omnidirectional wheels.

[0010] Furthermore, the fork length of the main chassis is greater than the fork length of the auxiliary chassis.

The output end of the telescopic device two is connected to a drive plate, and the drive plate is slidably connected to the drive guide rail. The lifting fork is located on the front side of the drive plate.

[0012] Furthermore, lifting sliders that cooperate with the drive guide rail are fixedly provided on both sides of the drive plate, and a lifting connecting block is provided on the back side of the drive plate.

[0013] Furthermore, the first telescopic device and the second telescopic device are either pneumatic cylinders or hydraulic cylinders.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] 1. The present invention provides a transversely moving cable transport vehicle, which achieves the function conversion between longitudinal travel and transverse translation without relying on high-precision steering wheels by superimposing the main frame longitudinal travel mechanism and the auxiliary frame transverse travel mechanism, and cooperating with the lifting and switching of the drive component, thereby reducing the cost of component procurement.

[0016] 2. The present invention provides a transversely moving cable transport vehicle, wherein the telescopic device in the drive assembly can quickly drive the auxiliary base frame to rise and fall. When the auxiliary base frame touches the ground, the transverse walking mechanism takes over the movement control, and the longitudinal walking wheels and longitudinal drive wheels lift off the ground simultaneously to avoid interference; conversely, when the auxiliary base frame is raised, the longitudinal walking mechanism and longitudinal drive wheels of the main base frame touch the ground, realizing forward movement and turning, and adapting to the frequent changes of direction in cable transportation.

[0017] 3. The main limiting back plate of the main base frame of this utility model is fixed on the drive guide rail by the limiting slider, so that the main base frame moves along the preset track when moving longitudinally. Combined with the omnidirectional wheels in the longitudinal traveling wheels, it can not only ensure straight-line travel, but also achieve smooth turning when turning. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1 and Figure 2 An integrated formwork for supporting the middle of adjacent walls according to this embodiment includes:

[0028] This utility model provides a transversely moving cable transport vehicle, including a central control vehicle body 1. The front end of the central control vehicle body 1 is provided with a vertically erected support frame 2. The support frame 2 is provided with a fork assembly 3 on its lower side. The fork assembly 3 includes a main base frame 301 and an auxiliary base frame 302 superimposed on the lower side of the main base frame 301. The main base frame 301 is provided with a longitudinal traveling mechanism 4 at the ground contact end. The auxiliary base frame 302 is provided with a transverse traveling mechanism 5 at the ground contact end. The support frame 2 is provided with a drive assembly. The drive assembly can drive the auxiliary base frame 302 to move toward the ground so that the transverse traveling mechanism 5 touches the ground and the longitudinal traveling mechanism 4 moves away from the ground.

[0029] Reference Figure 3 and Figure 4 The drive assembly includes a telescopic device 202 mounted on the support frame 2. The auxiliary base frame 302 has an auxiliary limiting back plate 7. The auxiliary limiting back plate 7 is slidably connected to the support frame 2. The power output shaft of the telescopic device 202 is connected to the auxiliary limiting back plate 7 to drive the auxiliary base frame 302 to move toward the ground so that the lateral walking mechanism 5 touches the ground.

[0030] Reference Figure 4 The auxiliary limiting back plate 7 is fixedly provided with driving sliders 701 on both sides, and the support frame 2 is provided with a driving guide rail 201 that cooperates with the driving sliders 701. The driving sliders 701 and the driving guide rail 201 are slidably connected.

[0031] Reference Figure 4 The auxiliary limiting back plate 7 is provided with a drive connecting block 702. The power output shaft of the telescopic device 202 is connected to the drive connecting block 702. The support frame 2 is provided with a guide rod 203. The drive connecting block 702 is sleeved on the guide rod 203 and slidably connected to the guide rod 203.

[0032] The transverse moving cable transport vehicle provided in this embodiment has a core structure consisting of a central control vehicle body 1, a support frame 2, a fork assembly 3, and a drive system. The support frame 2, which is vertically erected at the front end of the central control vehicle body 1, is made of steel. Drive rails 201 are symmetrically installed on the front sides of the two columns. The cross-section of the rails is a dovetail groove structure, which forms an interlocking sliding connection with the drive sliders 701 on both sides of the auxiliary limiting back plate 7, thereby limiting the lifting and lowering of the auxiliary base frame 302.

[0033] The fork assembly 3 comprises a main base frame 301 and an auxiliary base frame 302 stacked vertically. The forks of the main base frame 301 are made of I-beam steel, and their length exceeds that of the forks of the auxiliary base frame 302 by 20%. The excess portion is used to install longitudinal travel wheels 401 to avoid interference. The fork assembly 3 forms a forward-extending load-bearing structure. The longitudinal travel mechanism 4 at the ground contact end of the main base frame 301 consists of a pair of casters. The casters are mounted on the bottom of the forks through shock-absorbing bushings to absorb vibrations caused by uneven ground. Two pairs of transverse travel wheels 501 are symmetrically arranged at the bottom of the forks of the auxiliary base frame 302. The travel wheels are made of polyurethane coated material to enhance ground friction and quietness.

[0034] The telescopic device 202 in the drive assembly uses a double-acting cylinder. The cylinder body is fixed to the bottom crossbeam of the support frame 2 via a flange. One end of the piston rod is fixedly connected to the drive connecting block 702 in the middle of the auxiliary limiting back plate 7. The drive connecting block 702 has a guide hole in its center and is fitted onto the guide rods 203 on the inner side of the columns on both sides of the support frame 2. The two ends of the guide rods 203 are fixedly installed to the support frame 2, forming a vertical guide shaft that runs through the main base frame 301 and the auxiliary base frame 302. When the cylinder piston rod extends, the drive connecting block 702 slides downward along the guide rod 203, causing the auxiliary limiting back plate 7 to move synchronously downward on the drive guide rail 201 via the drive slider 701 until the transverse traveling wheel 501 of the auxiliary base frame 302 touches the ground. After touching the ground, a further downward force is applied, causing the longitudinal traveling mechanism 4 to lift away from the ground, just slightly above the ground, thereby eliminating the friction between the longitudinal traveling mechanism 4 and the ground and realizing the switching of the movement mode.

[0035] Reference Figure 5 The main base frame 301 has a main limiting back plate 8. The guide rod 203 is fixedly connected to the main limiting back plate 8. Limiting sliders 801 are fixedly provided on both sides of the main limiting back plate 8. The limiting sliders 801 are fixedly mounted on the drive guide rail 201.

[0036] Reference Figure 5 The longitudinal traveling mechanism 4 includes a pair of longitudinal traveling wheels 401, which are respectively disposed at the bottom ends of the two forks of the main chassis 301. The lateral traveling mechanism 5 includes two pairs of lateral traveling wheels 501, which are respectively disposed at the bottom ends of the two forks of the auxiliary chassis 302. The lower end of the central control vehicle body 1 is provided with a pair of longitudinal drive wheels 6, and the longitudinal traveling wheels 401 are omnidirectional wheels. The longitudinal drive wheels 6 can be driven by a differential drive motor.

[0037] Reference Figure 5The main base frame 301 is stacked on the upper side with a lifting fork 303. The support frame 2 is provided with a telescopic device 2. The output end of the telescopic device 2 is connected to a drive plate 9. The drive plate 9 is slidably connected to the drive guide rail 201. The lifting fork 303 is located on the front side of the drive plate 9.

[0038] The drive plate 9 has lifting sliders 901 fixed on both sides and installed in conjunction with the drive guide rail 201. The drive plate 9 has a lifting connecting block 902 on its back side. The lifting connecting block 902 is sleeved on the guide rod 203 and slidably connected to the guide rod 203. The power output shaft of the telescopic device 204 is connected to the lifting connecting block 902.

[0039] The telescopic device 1 202 and the telescopic device 204 are either pneumatic cylinders or hydraulic cylinders.

[0040] The lifting forks 303 stacked on the upper side of the main base frame 301 are vertically adjustable via a telescopic device 204. The telescopic device 204 uses a hydraulic cylinder, and the cylinder output shaft is fixedly connected to the lifting connecting block 902 on the back side of the drive plate 9. The lifting sliders 901 on both sides of the drive plate 9 are embedded in the grooves of the drive guide rail 201, and the lifting forks 303 are fixed to their front sides with bolts. When the hydraulic cylinder works, the lifting connecting block 902 slides up and down along the guide rod 203, driving the drive plate 9 to move synchronously on the drive guide rail 201, so that the cable reel 10 is away from the ground. Similarly, the distance between the two forks of the lifting fork 303 is smaller than the distance between the two forks of the main base frame 301 and the auxiliary base frame 302, so as to avoid interference between the main fork, the auxiliary fork and the cable reel 10 during operation.

[0041] During operation, in the normal longitudinal travel mode, the piston rod of the cylinder of the telescopic device 202 extends, causing the auxiliary limiting back plate 7 to slide upward on the drive guide rail 201 via the drive slider 701. The auxiliary base frame 302 rises accordingly until the lateral travel wheels 501 of the auxiliary base frame 302 are completely off the ground, and the longitudinal travel wheels 401 of the main base frame 301 contact the ground. At this point, the longitudinal travel wheels 401 are in contact with the ground, while the lateral travel wheels 501 are suspended in the air, ensuring no interference during longitudinal movement.

[0042] When moving forward or turning, a pair of longitudinal drive wheels 6 at the lower end of the central control vehicle body 1 are activated, enabling the vehicle to move forward and turn. The omnidirectional wheels adapt to the direction of the longitudinal drive wheels 6.

[0043] When loading the cable reel 10, move the vehicle body next to the cable reel 10, and adjust the height of the lifting forks 303 using the telescopic device 204 so that the forks of the lifting forks 303 contact the side of the cable reel 10. Then, move the vehicle body longitudinally; the two forks of the lifting forks 303 can be configured into a V-shape to provide better support for the cable reel 10. Next, raise the lifting forks 303 to lift the cable reel 10 off the ground.

[0044] Reference Figure 6 When switching to the lateral movement mode, the piston rod of the cylinder of the telescopic device 202 retracts, and the drive connecting block 702 slides downward along the guide rod 203, causing the auxiliary limiting back plate 7 to move synchronously downward on the drive guide rail 201 via the drive slider 701. The auxiliary base frame 302 descends until the lateral travel wheel 501 touches the ground. At this time, a downward force is continued to be applied, causing the longitudinal travel mechanism 4 to lift up. Both the longitudinal travel wheel 401 and the longitudinal drive wheel 6 are slightly higher than the ground. Because the weight of the cable reel is distributed on the lifting fork 303, and there are two pairs of lateral travel wheels 501, the auxiliary base frame 302 is evenly stressed and will not tip forward or backward. At this time, because the friction with the ground is removed, the movement mode is switched from longitudinal to lateral. The drive motor of the lateral travel mechanism 5 starts, and drives the two pairs of lateral travel wheels 501 at the bottom of the forks of the auxiliary base frame 302 to rotate synchronously through the synchronous belt drive. Since the lateral travel wheels 501 are made of polyurethane coated material, the ground friction is enhanced, and the vehicle body can move smoothly 90° laterally, which meets the needs of lateral movement in cable transportation.

[0045] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
