Description

Technical Field

[0001] The utility model relates to the field of carriage anti-sinking devices, in particular to a carriage anti-sinking device used in a loading system. Background Art

[0002] The existing loading system is equipped with lifting platforms, transverse conveyors, chain conveyors, lifting conveyors and other equipment to transport pallet materials to the rear of the container. At this time, the lifting platform and the bottom of the container are docked and fixed, and then a transport trolley travels back and forth between the lifting platform and the container to fork the materials and transport them into the container, thereby realizing rapid loading of materials.

[0003] However, as the loading progresses, the container load increases and the leaf springs are compressed, causing the container floor to sink to a certain height, resulting in the container floor being lower than the lifting platform. The two are connected in an inclined state, which in turn causes the transport trolley to tilt downward when transporting materials from the lifting platform into the container. The front fork and materials of the transport trolley will be directly pressed against the container floor and unable to move, that is, the transport trolley cannot move smoothly between the lifting platform and the container, which hinders the smooth loading of materials.

[0004] The purpose of this utility model is to design a car body anti-sinking device for a loading system in response to the problems existing in the above-mentioned prior art. Utility Model Content

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides a car body anti-sinking device for a loading system, which can effectively solve the problems existing in the above-mentioned prior art.

[0006] The technical solution of the utility model is:

[0007] A carriage anti-sinking device for a loading system, comprising:

[0008] A base is detachably mounted below the rear portion of the crossbeam of the corresponding vehicle and is open at the top. The base has guide members extending left and right and two transverse blocks driven by a driving device to move toward or in opposite directions along the guide members.

[0009] An upper member, located laterally above the two transverse moving blocks;

[0010] A plurality of support members are arranged obliquely and are arranged front and back between the upper support member and the two transverse blocks and the front and rear opposite sides of the inner wall of the base. The upper ends of the support members are respectively rotatably connected to the front and rear sides of the upper support member, and the lower ends are respectively rotatably connected to the front and rear sides of the two transverse blocks; when the two transverse blocks move toward each other, the support members swing up to support the upper support member to push the rear part of the cross beam, and when the two transverse blocks move in opposite directions, the support members swing down to drive the upper support member to descend.

[0011] Furthermore, the front and rear inner recesses of the base are provided with slide grooves extending left and right, and the lower ends of several support members are respectively arranged between the upper top member and the two transverse blocks and the front and rear opposite sides of the slide grooves, and the front and rear sides of the lower ends of the support members on the front and rear sides are respectively slid left and right by pulleys and arranged in the corresponding slide grooves.

[0012] Furthermore, several of the support members include several inner support rods distributed on the left and right and several outer support rods located on the left and right outsides of the several inner support rods, the upper and lower ends of several of the outer support rods are respectively rotatably connected to the left and right parts of the upper support member and the far ends of the two transverse blocks, the upper and lower ends of several of the inner support rods are respectively rotatably connected to the middle part of the upper support member and the proximal ends of the two transverse blocks, the inner support rods and the outer support rods are both arranged in an arc shape, and the arc-shaped opening sides of the outer support rods on the left and right sides are arranged facing each other, and the arc-shaped opening sides of the inner support rods on the left and right sides are arranged oppositely; when several of the support members swing down to drive the upper support member to descend, the upper end and the arc-shaped opening side of the outer support rod respectively abut the arc-shaped opening side and the lower end of the inner support rod.

[0013] Furthermore, the number of the outer support rods is set to four and they are symmetrically distributed on the front and rear sides of the upper support member, the number of the inner support rods is set to two and they are symmetrically distributed on the front and rear sides of the upper support member, and the two inner support rods are symmetrically arranged along the center of the upper support member.

[0014] Furthermore, the guide member is two screw rods with opposite threads distributed on the left and right, the proximal ends of the two screw rods are connected by a coupling seat, and the distal ends are respectively provided with bearing seats fixed to the bottom inner of the base. The driving device is a rotating motor arranged on one side of the base and the driving end is connected to one of the screw rods. The two transverse blocks are respectively threaded on the threads of the two screw rods through nuts.

[0015] Furthermore, the threads on the outer walls of the two screw rods and the inner wall of the nut are both configured as trapezoidal threads with trapezoidal cross-sections.

[0016] Furthermore, a detection plate for detecting whether the upper push piece abuts against the bottom of the beam is provided on the top of the upper push piece, and the detection plate and the driving device are communicatively connected to a corresponding control system.

[0017] Furthermore, the base is provided with a first detection device for detecting the two transverse blocks moving toward each other to the closest position, and a second detection device for detecting the two transverse blocks moving oppositely to the farthest position. The first detection device and the second detection device are communicatively connected to the corresponding control system.

[0018] Therefore, the present invention provides the following effects and / or advantages:

[0019] 1. When the driving device drives the two transverse blocks to move toward each other, several support members swing upward to support the rear part of the upper crossbeam of the upper push member. When the two transverse blocks move in opposite directions, several support members swing downward to drive the upper push member to descend. Therefore, after the rear part of the crossbeam is lifted by the upper top piece, the loading system can then load the materials into the container of the vehicle, so that the height of the rear part of the bottom plate of the container does not sink during the material loading process, ensuring that it is always at the same height as the lifting platform of the loading system, so that the transport trolley can stably move between the lifting platform and the container, ensuring the efficiency of material loading; at the same time, by arranging a plurality of support members sideways and front and back and between the upper top piece and the two transverse blocks and the front and rear opposite sides of the inner wall of the base, instead of being conventionally arranged between the bottom of the upper top piece and the base, when the loading system completes loading and the vehicle needs to drive away, the lowering height of the upper top piece can be compressed, and then the height of the anti-sinking device when it is folded up as a whole can be compressed to avoid the anti-sinking device being too high when folded up and causing obstruction to the bumper on the rear side of the vehicle. The vehicle can pass smoothly without removing the anti-sinking device, which is convenient for the vehicle to drive away directly after loading and drive into the next vehicle to be loaded, ensuring loading efficiency.

[0020] 2. On the basis of the offset setting of the support rod, the connection between the lower end of the support member and the base is achieved by adding a slide groove and a pulley, so that when the upper supporting member pushes the crossbeam, the force of several supporting members can not only be transmitted to the transverse block for dispersion, but also be transmitted to the base through the roller and then dispersed, so as to provide double-sided support for the lower ends of several supporting members, thereby improving the support strength and stability after the lateral displacement setting of several supporting members.

[0021] 3. When the support members swing downward, driving the upper support member downward, the upper end and curved opening side of the outer support rod respectively abut the curved opening side and lower end of the inner support rod. The addition of the curved opening side of the inner support rod and the curved opening side of the outer support rod thus provide space for the upper end of the outer support rod and the lower end of the inner support rod. This allows the inner and outer support rods to overlap at a more compact height, further reducing the height of the upper support member. This allows the anti-sinking device to be adapted to vehicles with lower rear bumpers, improving its adaptability.

[0022] 4. The threads on the outer walls of the two screw rods and the inner walls of the nut are both trapezoidal threads with a trapezoidal cross-section. Therefore, when the upper push member pushes against the vehicle's crossbeam, the nut and screw rod, under pressure, can self-lock with each other through the trapezoidal threads, thereby preventing the two transverse blocks from sliding left and right. When a heavy weight presses on the upper push member, the drive device does not need to use a high-power motor to lock the screw rod, and can achieve the locking function of the support member. This improves the support stability of the anti-sinking device while reducing the drive cost.

[0023] It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the following embodiments and accompanying drawings:

[0031] refer to Figure 1-6 , a carriage anti-sinking device for a loading system, comprising:

[0032] The base 1 is detachably mounted below the rear portion of the crossbeam 81 of the corresponding vehicle 8 and has an open top. The base 1 is provided with left and right extending guide members at the bottom thereof, and two transverse movement blocks 5 driven by a drive device 6 to move toward or in opposite directions along the guide members. Specifically, the loading system 9 includes a lifting platform 91 for docking with and fixing to the container floor of the vehicle 8, a conveying device 92 for conveying materials to the lifting platform 91, and a transport trolley for traveling between the lifting platform 91 and the interior of the container and for transporting materials from the lifting platform 91 to the container.

[0033] An upper push member 2 is laterally located above the two transverse moving blocks 5. Specifically, the upper push member 2 is a transversely arranged crossbar;

[0034] A number of support members 3 are arranged obliquely and are arranged front and back between the upper support member 2 and the two transverse blocks 5 and the front and rear opposite sides of the inner wall of the base 1. The upper ends of the support members 3 are respectively rotatably connected to the front and rear sides of the upper support member 2, and the lower ends are respectively rotatably connected to the front and rear sides of the two transverse blocks 5; when the two transverse blocks 5 move toward each other, the support members 3 swing up to support the upper support member 2 and push the rear part of the cross beam 81. When the two transverse blocks 5 move in opposite directions, the support members 3 swing down to drive the upper support member 2 to descend.

[0035] The above structure is set up, after the upper support member 2 pushes the rear part of the cross beam 81, the loading system 9 can load the container of the vehicle 8 with materials, so that the height of the rear bottom plate of the container does not sink during the material loading process, ensuring that it is always at the same height as the lifting platform 91 of the loading system 9, so that the transport trolley can stably walk between the lifting platform 91 and the container, ensuring the efficiency of material loading; at the same time, by arranging the support members 3 sideways and front and back and between the upper support member 2 and the two transverse blocks 5 and the front and rear opposite sides of the slide 11, instead of being conventionally arranged between the bottom of the upper support member 2 and the base 1, when the loading system 9 completes the loading and the vehicle 8 needs to drive away, the lowering height of the upper support member 2 is compressed, and then the height of the anti-sinking device when it is folded up as a whole is compressed, so as to avoid the anti-sinking device being too high when folded up and causing obstruction to the bumper of the rear side of the vehicle 8, and the smooth passage of the vehicle 8 can be achieved without removing the anti-sinking device, so that the vehicle 8 can drive away directly after loading and drive into the next vehicle 8 to be loaded, ensuring loading efficiency.

[0036] In order to improve the supporting strength of the support rod, the front and rear inner recesses of the base 1 are provided with left and right extending grooves 11. The lower ends of the plurality of support members 3 are respectively arranged between the upper support member 2 and the two transverse blocks 5 and the front and rear opposite sides of the grooves 11. The front and rear sides of the lower ends of the support members 3 on the front and rear sides are respectively slid left and right in the corresponding grooves 11 via pulleys 7. Thus, on the basis of the offset setting of the support rod, the connection between the lower ends of the support members 3 and the base 1 is achieved by adding the grooves 11 and the pulleys 7. Therefore, when the upper support member 2 is placed on the crossbeam 81, the force of the plurality of support members 3 can not only be transmitted to the transverse blocks 5 for dispersion, but can also be transmitted to the base 1 through the rollers and then dispersed, so as to provide bilateral support for the lower ends of the plurality of support members 3, thereby improving the supporting strength and stability of the plurality of support members 3 after the lateral displacement setting.

[0037] In order to further compress the descending height of the upper support member 2, several of the support members 3 include several inner support rods 31 distributed on the left and right and several outer support rods 32 located on the left and right outsides of the inner support rods 31. The upper and lower ends of the outer support rods 32 are respectively rotatably connected to the left and right parts of the upper support member 2 and the far ends of the two transverse blocks 5. The upper and lower ends of the inner support rods 31 are respectively rotatably connected to the middle part of the upper support member 2 and the proximal ends of the two transverse blocks 5. The inner support rods 31 and the outer support rods 32 are both arranged in an arc shape, and the arc-shaped opening sides 33 of the outer support rods 32 on the left and right sides are arranged facing each other, and the arc-shaped opening sides 33 of the inner support rods 31 on the left and right sides are arranged oppositely; when the several support members 3 swing down to drive the upper support member 2 to descend, the upper end and the arc-shaped opening side 33 of the outer support rod 32 respectively abut the arc-shaped opening side 33 and the lower end of the inner support rod 31. Thus, by adding the arc-shaped opening side 33 of the inner support rod 31 and the arc-shaped opening side 33 of the outer support rod 32, the upper end of the outer support rod 32 and the lower end of the inner support rod 31 are given space, so that the height of the inner support rod 31 and the outer support rod 32 is more compact when the lower hems overlap, further compressing the descending height of the upper top member 2, so that the anti-sinking device can adapt to vehicles 8 with lower rear bumpers 82, thereby improving the adaptability of the anti-sinking device.

[0038] In order to reduce the number of support members 3 to reduce costs while ensuring the supporting strength of several support members 3 on the upper support member 2, the number of the outer support rods 32 is set to four and they are symmetrically distributed on the front and rear sides of the upper support member 2, and the number of the inner support rods 31 is set to two and they are distributed on the front and rear sides of the upper support member 2, and the two inner support rods 31 are symmetrically arranged along the center of the upper support member 2.

[0039] In order to stably realize the left and right direction movement or opposite movement of the two transverse blocks 5, the guide member is two screw rods 4 with opposite threads distributed on the left and right. The proximal ends of the two screw rods 4 are connected by a coupling seat 41, and the distal ends are respectively provided with bearing seats 42 fixed to the bottom of the base 1. The driving device 6 is a rotating motor provided on one side of the base 1 and the driving end is connected to one of the screw rods 4. The two transverse blocks 5 are respectively screwed on the threads of the two screw rods 4 through nuts. Specifically, the nuts are provided in the corresponding transverse blocks 5.

[0040] To reduce drive costs, the threads on the outer walls of the two screw rods 4 and the inner walls of the nut are both configured as trapezoidal threads 43 with a trapezoidal cross-section. Thus, when the upper push member 2 is pressed against the crossbeam 81 of the vehicle 8, the nut and screw rod 4, under pressure, can achieve mutual self-locking through the trapezoidal threads 43, thereby preventing the two transverse blocks 5 from sliding left and right in opposite directions. When a heavy weight presses on the upper push member 2, the drive device 6 can achieve the locking function of the support member 3 without using a high-power motor to lock the screw rod. This improves the support stability of the anti-sinking device while reducing drive costs.

[0041] To automate the lifting of the anti-sinking device and save manpower, a detection plate 21 is installed on the top of the upper member 2 to detect whether the upper member 2 abuts the bottom of the crossbeam 81. The detection plate 21 is connected to the drive device 6 and a corresponding control system. Specifically, the detection plate 21 is made of spring steel with good elasticity. This allows the control system to automatically control the amount of movement of the transverse block 5 by the drive device 6 based on the detection signal from the detection plate 21, thereby controlling the height of the upper member 2 caused by the upward swing of the support member 3, automatically adapting to vehicles 8 with different crossbeam 81 heights.

[0042] In order to improve the stability of the anti-sinking device, the base 1 is provided with a first detection device 12 for detecting the two transverse blocks 5 moving toward each other to their closest position, and a second detection device 13 for detecting the two transverse blocks 5 moving in opposite directions to their farthest positions. The first detection device 12 and the second detection device 13 are communicatively connected to a corresponding control system. Specifically, the first detection device 12 and the second detection device 13 are both position sensors. The detection lever of the first detection device 12 extends into the base 1 and corresponds to the right side of the outer support rod 32 on the left rear side, while the detection lever of the second detection device 13 extends into the base 1 and corresponds to the right side of the transverse block 5 on the right side. Thus, by adding the first detection device 12 and the second detection device 13, the control system can determine whether the two transverse blocks 5 are moving toward each other to their closest position or in opposite directions to their farthest position based on their detection signals. If so, the control system controls the drive device 6 to stop driving, thereby preventing the nut in the transverse block 5 from disengaging from the thread on the screw rod 4, resulting in drive failure, thereby improving the driving stability of the drive device 6.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
