Description

Technical Field

[0001] The present invention relates to the technical field of tractor trucks, and particularly to a remotely controlled tractor truck. Background Art

[0002] Remotely controlled tractor trucks have been widely used in the field of cargo transportation. The main function of a remotely controlled tractor truck is to automatically tow a trailer loaded with goods to complete the transfer of goods.

[0003] Currently, a pin connection method with multiple holes is often used to pin the towing component for attaching the trailer to the remotely controlled tractor truck. Through this pin connection method with multiple holes, the height of the towing component can be adjusted to adapt to the attachment of trailer mops at different heights, enhancing the practicability. However, every time the staff adjusts the position of the towing component, they still need to manually install multiple towing pins between the towing component and the tractor truck to complete the fixed connection between the two. Due to manually assembling multiple towing pins, the operation will be relatively complicated and cumbersome, resulting in an increase in the work intensity. Therefore, we have proposed a remotely controlled tractor truck. Summary of the Invention

[0020] (III) Beneficial effects

[0021] The present invention provides a remote-controlled tractor, which has the following beneficial effects:

[0022] 1. By adding a traction member, a connecting member, a hydraulic rod, and an automatic latch mechanism, etc., control the hydraulic rod to drive the automatic latch mechanism to move to an appropriate height. The staff lifts the traction member to an appropriate position of the connecting member, and then controls the automatic latch mechanism so that the latch members on both sides are inserted between the connecting pin hole 1 and the connecting pin hole 2, thus completing the pin connection between the connecting member and the traction member. There is no need for the staff to manually perform the pin connection, which greatly simplifies the operation and also reduces the working intensity of the staff.

[0023] 2. By adding a latch member, when the pin shaft inserted between the connecting pin hole 1 and the connecting pin hole 2 breaks, the pin shaft can be rotated and removed, and then by reverse operation, a new pin shaft can be threadedly installed on the connection. The installation and disassembly of the pin shaft are relatively convenient.

[0024] 3. By adding an anti-deflection mechanism, after the groove is aligned with the slot, then compress the elastic telescopic plate by hand and rotate it to align with the slot, and then slowly release the elastic telescopic plate so that it is inserted into the slot, effectively preventing relative rotation between the pin shaft and the connecting column, avoiding the pin shaft falling off from the connecting column, and ensuring the normal use of the tractor for a long time.

[0025] 4. By adding a plugging mechanism, insert the plugging block on the traction block into the plugging sleeve until the positioning block is inserted into the positioning port, then the traction block can be fixed on the moving shell. When the moving shell moves, the adjustment of the height of the traction block can be realized. Before pin-connecting the connecting member and the traction member, there is no need for manual lifting of the traction member to align the connecting pin hole 1 and the connecting pin hole 2, which is more time-saving and labor-saving.

[0026] 5. By adding an ejection mechanism, control the pin shaft to be withdrawn from the connecting pin hole 1 and the connecting pin hole 2, then control the hydraulic rod to drive the traction member to move downward. When the positioning block moves downward and abuts against the ejection plate, control it to continue to move downward until the protruding part of the ejection plate extends into the positioning port, and then pull out the traction member outward, which makes the disassembly of the traction member relatively convenient.

[0027] In summary, the present invention does not require manual pin connection by the staff, greatly simplifies the operation, and the loading and unloading of the traction member are also relatively convenient, which is more time-saving and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0041] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0042] Embodiment 1

[0043] As Figures 1 - 11 shown, a remote-controlled tractor includes a towing vehicle body 1. A connecting member 2 is provided on the towing vehicle body 1. A towing member 3 is correspondingly connected to the connecting member 2. An automatic pin insertion mechanism 5 for pin connection is provided between the towing member 3 and the connecting member 2. A hydraulic rod 4 for driving the automatic pin insertion mechanism 5 to move is installed on the towing vehicle body 1. Specifically, a support frame 12 is further provided between the towing vehicle body 1 and the hydraulic rod 4. The support frame 12 is fixed to the towing vehicle body 1, and the hydraulic rod 4 is installed on the support frame 12. Among them, by controlling the hydraulic rod 4, the automatic pin insertion mechanism 5 can be driven to move vertically, and the height of the towing member 3 can be adjusted, improving the practicability; the automatic pin insertion mechanism 5 can automatically pin-connect the connecting member 2 and the towing member 3, eliminating the need for staff to manually install the towing pin shaft between the connecting member 2 and the towing member 3, greatly simplifying the operation and reducing the working intensity of the staff.

[0044] Specifically, the connecting member 2 includes a plurality of first connecting pin holes 22. The connecting member 2 further includes two connecting pin plates 21 fixed to the towing vehicle body 1. The first connecting pin holes 22 are opened on the connecting pin plates 21. Specifically, the towing member 3 includes a plurality of second connecting pin holes 32. The number of the second connecting pin holes 32 is two or more. Here, three second connecting pin holes 32 are selected. The towing member 3 further includes a towing block 31. A hook 34 is provided on the towing block 31, and an external hanging pin hole 33 is opened on the towing block 31. The hook 34 and the external hanging pin hole 33 can be used to hang the mop of the trailer. The second connecting pin holes 32 are opened on the towing block 31. Among them, both the first connecting pin holes 22 and the second connecting pin holes 32 are circular pin holes and have the same size.

[0045] The automatic latch mechanism 5 includes a moving shell 51 fixed to the movable end of the hydraulic rod 4, a motor 57 is installed on the moving shell 51, and a rotating shaft 58 connected to the moving shell 51 with rotation damping is fixed at the output end of the motor 57. Through the damping connection, even if the motor 57 fails and loses its self-locking ability, the rotating shaft 58 will not easily deflect, so as to ensure that the pin shaft 552 will not easily disengage from the connecting pin hole 1 22 and the connecting pin hole 2 32, thereby improving stability. A rotating plate 52 is fixed on the rotating shaft 58, and eccentric rods 53 are fixed on both side ends of the rotating plate 52. A connecting rod 54 is rotatably mounted on the eccentric rod 53, and a latch group slidably mounted with the moving shell 51 is rotatably mounted on the other end of the connecting rod 54; the latch group includes a plurality of latch members 55 for pin-connecting the connecting pin hole 1 22 and the connecting pin hole 2 32, the latch member 55 in the middle position is rotatably mounted with one end of the corresponding connecting rod 54 away from the rotating plate 52, and the same vertical rod 56 is fixed between the latch members 55 on the same side. Among them, after adjusting the connecting pin hole 22 on the traction block 32 to a suitable height and aligning the connecting pin hole 22 with the corresponding connecting pin hole 1 22, the motor 57 is started to drive the rotating plate 52 and the eccentric rod 53 thereon to rotate, and through the transmission of the connecting rods 54 on both sides, the pin groups on both sides are driven to move outward at the same time until the pin member 55 on the pin group is inserted between the connecting pin hole 1 22 and the connecting pin hole 2 32, thereby completing the pin connection between the connecting member 2 and the traction member 3, without the need for manual pin connection by the staff, which greatly simplifies the operation and reduces the workload of the staff.

[0046] In summary, according to the height of the mop of the trailer to be towed, the hydraulic rod 4 is started to drive the automatic latch mechanism 5 to move to a suitable height in the vertical direction. The staff lifts the traction member 3 to a suitable position of the connecting member 2 so that the connecting pin hole 1 22 and the connecting pin hole 2 32 are aligned. Then the automatic latch mechanism 5 is controlled so that the latch members 55 on both sides are inserted between the connecting pin hole 1 22 and the connecting pin hole 2 32. The pin connection between the connecting member 2 and the traction member 3 can be completed without the need for manual pin connection by the staff, which greatly simplifies the operation and reduces the workload of the staff.

[0047] In this embodiment, a connecting plate 9 for improving stability is fixed between the two connecting pin plates 21, a slide groove 11 is provided on the connecting plate 9, and a slide bar 10 slidably installed in the slide groove 11 is fixed on the moving shell 51, the slide groove 11 is set as a T-shaped slide groove, and the slide bar 10 is also set as a T-shaped slide bar adapted to the slide groove 11. The setting of the slide groove 11 and the slide bar 10 improves the stability of the moving shell 51 when it moves in the vertical direction.

[0048] Example 2

[0049] The amount of cargo towed by a tractor is often large. As an important structure connecting the tractor and the cargo, the stress condition of the traction pin is extremely complex. Under the action of a large amount of cargo towed, any form of impact may cause the traction pin to break.

[0050] refer to Figures 8 - 9 , which is basically the same as the first embodiment, is more optimized in that the latch member 55 comprises a connecting column 551 and a pin 552, the connecting column 551 is provided with a screw hole 554, and the pin 552 is fixed with a screw rod 553 adapted to the screw hole 554. When the pin 552 inserted between the connecting pin hole 1 22 and the connecting pin hole 2 32 breaks, the pin 552 can be rotated and removed, and then the new pin 552 can be threadedly installed on the connecting column 551 by reverse operation, so that the installation and removal of the pin 552 are relatively convenient.

[0051] Example 3

[0052] Due to long-term friction and shaking between the connecting pin hole 1 22 and the connecting pin hole 2 32, the pin shaft 552 may deflect from the connecting column 551, eventually causing the pin shaft 552 to fall off from the connecting column 551. The falling off of the pin shaft 552 will affect the normal traction use of the tractor.

[0053] refer to Figures 8 - 9 , which is basically the same as the first embodiment, and is more optimized in that an anti-deflection mechanism 6 is provided between the connecting column 551 and the pin shaft 552, and the anti-deflection mechanism 6 includes a groove 61 provided on the connecting column 551 and a slot 64 provided on the pin shaft 552, and an elastic telescopic plate 62 plugged with the slot 64 is rotatably installed in the groove 61, and a dial plate 63 for shifting is fixed to the telescopic part of the elastic telescopic plate 62, and the arrangement of the dial plate 63 facilitates the staff to shift the dial plate 63 with their fingers to compress the elastic telescopic plate 62. Among them, after the pin shaft 552 is tightened with the connecting column 551, at this time, the groove 61 is directly opposite to the slot 64, and then the elastic telescopic plate 62 is manually compressed and rotated, so that the elastic telescopic plate 62 is aligned with the slot 64, and then the elastic telescopic plate 62 is slowly loosened until the telescopic part of the elastic telescopic plate 62 is inserted into the slot 64, effectively preventing the relative rotation between the pin shaft 552 and the connecting column 551, and preventing the pin shaft 552 from falling off from the connecting column 551, thereby ensuring the normal use of the tractor.

[0054] Example 4

[0055] refer to Figure 10, which is basically the same as Embodiment 1. More optimally, a plugging mechanism 7 is provided between the moving shell 51 and the traction block 31. The plugging mechanism 7 includes a plugging sleeve 71 fixed on the moving shell 51 and a plugging block 74 fixed on the traction block 31 and adapted to the plugging sleeve 71. Both the plugging sleeve 71 and the plugging block 74 are arranged in a rectangular shape. A positioning port 72 is formed on the plugging sleeve 71, and a strip-shaped groove 75 is formed on the plugging block 74. A positioning block 77 inserted into the positioning port 72 is slidably installed in the strip-shaped groove 75, and a spring 76 is installed between the positioning block 77 and the strip-shaped groove 75. Among them, align the plugging block 74 on the traction block 31 with the plugging sleeve 71, and push the traction block 31 inward until the positioning block 77 is inserted into the positioning port 72 under the elastic action of the spring 76, then the traction block 31 can be fixedly connected to the moving shell 51. When the moving shell 51 moves, it drives the traction block 31 to move vertically, and the adjustment of the height of the traction block 31 can be realized. Before pin-connecting the connecting member 2 and the traction member 3, there is no need for manual lifting of the traction member 3 to align the connecting pin hole 1-22 and the connecting pin hole 2-32, which is more time-saving and labor-saving.

[0056] Further, the open end of the plugging sleeve 71 is provided with an arc-shaped surface 73 for the smooth insertion of the plugging block 74.

[0057] Embodiment 5

[0058] Reference Figure 11 , which is basically the same as Embodiment 1. More optimally, a jacking mechanism 8 is provided on the connecting pin plate 21. The jacking mechanism 8 includes a support rod 81 fixed on the connecting pin plate 21. A connecting rod 82 is fixed on the support rod 81, and a jacking plate 83 is fixed at the other end of the connecting rod 82. The protruding part of the jacking plate 83 is adapted to the positioning port 72. Among them, when it is necessary to remove the traction member 3 for maintenance, first control the automatic pin insertion mechanism 5 to withdraw the pin shaft 552 from the connecting pin hole 1-22 and the connecting pin hole 2-32. Then control the hydraulic rod 4 to drive the moving shell 51, the plugging mechanism 7 and the traction member 3 to move downward. When the positioning block 77 moves downward and abuts against the jacking plate 83, control it to continue to move downward until the protruding part of the jacking plate 83 extends into the positioning port 72 (at this time, the top end of the protruding part of the jacking plate 83 is flush with the inner end surface of the positioning port 72), and then pull out the traction member 3 outward, so that the disassembly of the traction member 3 is more convenient.

[0059] The remote control tractor in the present invention uses the automatic pin insertion mechanism 5 to solve the problem that the staff manually pins the traction member 3 and the connecting member 2, greatly simplifies the operation. At the same time, the loading and unloading of the traction member 3 are also more convenient, which is more time-saving and labor-saving.
