Description
Technical Field
[0001] The invention relates to the technical field of loading and unloading equipment, in particular to cargo loading and unloading equipment for road transportation of paper printed matter. Background Art
[0002] With the development of science and technology, large-scale forklifts and full manual labor have gradually developed into the current semi-automatic equipment. At present, there are mature automation solutions and implementation experience in warehousing, handling, sorting, palletizing and other links. Only loading and unloading operations are basically still in a manual or semi-automatic state. For loading and unloading work, due to the limitation of site homogeneity, manual mode or forklift is generally used for handling, unloading goods from pallets and then stacking goods, which reduces the efficiency of cargo handling, and manual stacking of goods is time-consuming and labor-intensive; At present, there are still the following problems when loading and unloading paper printed materials: first, when moving the paper printed materials to an external vehicle, since the object to be transmitted is generally a rope, the paper printed materials will shake during the movement, making it inconvenient to place them stably on the placement station, thereby increasing the loading and unloading time; second, since the paper printed materials are in a state of deviating from the top of the mobile vehicle itself during loading and unloading, the center of gravity of the mobile vehicle will shift, and the mobile vehicle is prone to tipping over during loading and unloading.
[0003] In view of the above technical defects, a solution is now proposed. Summary of the invention
[0004] The object of the present invention is to provide a cargo loading and unloading device for road transportation of paper printed materials. The device slides and engages with the mounting plate and the card slot in the loading and unloading mechanism and the auxiliary mechanism, so that the support plate will not shake during the movement. This not only speeds up the stacking speed of paper printed materials, but also improves the efficiency of loading and unloading them. At the same time, when the paper printed materials are moved to an external transport vehicle, the center of gravity of the mobile vehicle is ensured to be still directly above the mobile vehicle itself, thereby avoiding the mobile vehicle from tipping over when stacking paper printed materials. This solves the problem in the prior art that it is difficult to prevent paper printed materials from shaking during movement, thereby speeding up the loading and unloading time and improving the loading and unloading efficiency and affecting the loading and unloading efficiency; when loading and unloading paper printed materials, it is difficult to avoid the center of gravity of the mobile vehicle from shifting, causing it to tip over.
[0005] To achieve the above object, the present invention provides the following technical solutions: A cargo loading and unloading device for road transportation of paper printed materials, comprising a mobile vehicle, a loading and unloading mechanism is arranged on the top of the mobile vehicle, an auxiliary mechanism is connected to the top of the loading and unloading mechanism, a lifting tool is installed on one side of the loading and unloading mechanism, and the top of the lifting tool is connected to the mobile mechanism through a fixed plate; The loading and unloading mechanism includes a placement rack fixedly connected to the top of the mobile vehicle, a hydraulic cylinder is fixedly installed on the side of the placement rack close to the lifting tooling, a counterweight block is fixedly connected to the output end of the hydraulic cylinder, the counterweight block is slidably matched with the outer wall of the top of the mobile vehicle, a first limiting column is fixedly connected to the outer walls of the front and back of the counterweight block, a transmission plate is rotatably connected to the outer walls of the front and back of the placement rack through a pin, a first limiting groove is opened at the bottom end of the transmission plate, and the first limiting groove on the same side is transmission-matched with the first limiting column, and a transmission assembly is arranged above the two transmission plates.
[0006] Furthermore, the transmission assembly includes a slide plate fixedly connected to the lifting tooling, the upper part of the slide plate is slidably connected to a limit plate, a slot is provided on the outer wall of the limit plate on the side away from the lifting tooling, and a second limit column is fixedly connected to the outer walls of the limit plate close to the front and back of the lifting tooling, a second limit groove is provided on the top of the transmission plate, and the second limit groove on the same side cooperates with the second limit column for transmission.
[0007] Furthermore, the auxiliary mechanism includes a support plate in contact with the top of the placement rack, a mounting plate is fixedly connected to a side of the support plate close to the lifting tooling, and the mounting plate and the support plate are connected by two connecting plates.
[0008] Furthermore, the mounting plate is slidably matched with the card slot, and a paper print is arranged above the mounting plate.
[0009] Furthermore, the moving mechanism includes a guide rail fixedly connected to the top of the lifting tooling, the guide rail is located above the moving vehicle, a guide sleeve is sleeved on the outer wall of the guide rail, the upper part of the guide sleeve is coordinated with the guide rail through a roller transmission, and the bottom end of the guide sleeve is fixedly connected to a rope.
[0010] Furthermore, the paper printed matter is sleeved on the outer wall below the rope.
[0011] Furthermore, a method for using cargo handling equipment for road transportation of paper printed materials comprises the following steps: Step 1: When the paper printed matter needs to be loaded onto an external transport vehicle, first, the paper printed matter is neatly placed on the support plate, and then the mobile vehicle is pushed to transport it to the loading and unloading station. At this time, the lifting tool is turned on to move the guide rail upward, and the paper printed matter on the support plate is driven upward by the rope to meet the requirements of loading and unloading paper printed matter on transport vehicles of different heights; Step 2: At the same time, the mounting plate is slidably engaged with the card slot, and the output end thereof is retracted from the longest state by opening the hydraulic cylinder, which not only drives the counterweight block to move toward the lifting tooling, but also cooperates with the transmission plate to drive the limit plate to move toward the paper printed matter. As the guide sleeve and the roller move on the guide rail, the limit plate will stably push the paper printed matter on the support plate toward the external transport vehicle, and the mounting plate is slidably engaged with the card slot, so that the support plate will not shake during the movement; Step three, when the paper printed materials are moved to the external transport vehicle, the paper printed materials will deviate from the top of the mobile vehicle itself.

The mounting plate is slidably engaged with the card slot, so that the support plate will not shake during the movement, which not only speeds up the stacking speed of paper printed matter, but also improves the efficiency of loading and unloading thereof. In the present invention, when the paper printed matter is moved to an external transport vehicle, the paper printed matter will deviate from the top of the mobile vehicle itself. Since the counterweight block moves toward the lifting tooling, it is ensured that the center of gravity of the mobile vehicle is still directly above the mobile vehicle itself, thereby avoiding the mobile vehicle from tipping over when stacking paper printed matter.

DETAILED DESCRIPTION
[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0016] Embodiment 1 like Figure 1-6 As shown, the present embodiment provides a cargo loading and unloading device for road transportation of paper printed materials, comprising a mobile vehicle 3, a loading and unloading mechanism 4 is arranged on the top of the mobile vehicle 3, an auxiliary mechanism 5 is connected to the top of the loading and unloading mechanism 4, a lifting device 2 is installed on one side of the loading and unloading mechanism 4, the lifting device 2 is a hydraulic lift, and a moving mechanism 7 is connected to the top of the lifting device 2 through a fixed plate 1; The loading and unloading mechanism 4 includes a placement rack 46 fixedly connected to the top of the mobile vehicle 3. A hydraulic cylinder 42 is fixedly installed on one side of the placement rack 46 close to the lifting tool 2. A counterweight 44 is fixedly connected to the output end of the hydraulic cylinder 42. The counterweight 44 slides with the outer wall of the top of the mobile vehicle 3. The front and back outer walls of the counterweight 44 are fixedly connected with a first limiting column 43. The front and back outer walls of the placement rack 46 are rotatably connected with a transmission plate 41 through a latch. The bottom end of the transmission plate 41 is provided with a first limiting groove 45, and the first limiting groove 45 on the same side is in transmission cooperation with the first limiting column 43. A transmission assembly 47 is arranged above the two transmission plates 41. When the paper printed matter is moved to the external transport vehicle, the paper printed matter will deviate from the top of the mobile vehicle 3 itself. Since the counterweight 44 moves toward the lifting tool 2, it is ensured that the center of gravity of the mobile vehicle 3 is still directly above the mobile vehicle 3 itself, thereby avoiding the mobile vehicle 3 from tipping over when stacking paper printed matters.
[0017] The transmission assembly 47 includes a slide plate 473 fixedly connected to the lifting fixture 2, a limit plate 475 is slidably connected to the upper side of the slide plate 473, a slot 474 is provided on the outer wall of the limit plate 475 on the side away from the lifting fixture 2, and a second limit column 471 is fixedly connected to the outer wall of the limit plate 475 close to the front and back of the lifting fixture 2, a second limit groove 472 is provided on the top of the transmission plate 41, and the second limit groove 472 on the same side is in transmission cooperation with the second limit column 471, the mounting plate 51 is slidably engaged with the slot 474, and the hydraulic cylinder 42 is turned on to make the hydraulic cylinder 42 move upward. The output end of the support plate 53 contracts from its longest state, which not only drives the counterweight block 44 to move toward the lifting tooling 2, but also cooperates with the transmission plate 41 to drive the limit plate 475 to move toward the paper printed matter. As the guide sleeve 71 and the roller 74 move on the guide rail 73, the limit plate 475 will stably push the paper printed matter on the support plate 53 to move toward the external transport vehicle. The mounting plate 51 is slidably engaged with the card slot 474, so that the support plate 53 will not shake during the movement, which not only speeds up the stacking speed of the paper printed matter, but also improves the efficiency of its loading and unloading.
[0018] Embodiment 2 like Figure 1 , 5 As shown, the present embodiment proposes a cargo loading and unloading device for road transport of paper printed materials, which is improved on the basis of the embodiment 1, and the auxiliary mechanism 5 includes a support plate 53 in contact with the top of the placement rack 46, and the support plate 53 is fixedly connected to a mounting plate 51 on one side close to the lifting tooling 2, and the mounting plate 51 and the support plate 53 are connected by two connecting plates 54.
[0019] The mounting plate 51 is slidably matched with the card slot 474 , and a paper printed matter 6 is arranged above the mounting plate 51 .
[0020] like Figure 1 , 6 As shown, the moving mechanism 7 includes a guide rail 73 fixedly connected to the top of the lifting tool 2, the guide rail 73 is located above the mobile vehicle 3, and a guide sleeve 71 is sleeved on the outer wall of the guide rail 73. The upper part of the guide sleeve 71 and the guide rail 73 are matched through a roller 74. The bottom end of the guide sleeve 71 is fixedly connected to a rope 72, and the paper printed products are neatly placed on the support plate 53, and are transported to the loading and unloading station by pushing the mobile vehicle 3. At this time, the lifting tool 2 is turned on, so that the guide rail 73 moves upward, and the rope 72 drives the paper printed products on the support plate 53 to move upward, so as to meet the requirements of loading and unloading paper printed products on transport vehicles of different heights.
[0021] The paper printed matter 6 is sleeved on the outer wall below the rope 72 .
[0022] The working process and principle of the present invention are as follows: Step 1: When the paper printed matter needs to be loaded onto an external transport vehicle, first, the paper printed matter is neatly placed on the support plate 53, and the mobile vehicle 3 is pushed to transport the paper printed matter to the loading and unloading station. At this time, the lifting device 2 is opened to move the guide rail 73 upward, and the rope 72 is used to drive the paper printed matter on the support plate 53 to move upward, so as to meet the requirements of loading and unloading paper printed matter on transport vehicles of different heights; Step 2: At the same time, the mounting plate 51 is slidably engaged with the card slot 474, and the output end thereof is retracted from the longest state by opening the hydraulic cylinder 42, which not only drives the counterweight block 44 to move toward the lifting fixture 2, but also cooperates with the transmission plate 41 to drive the limit plate 475 to move toward the paper printed matter. As the guide sleeve 71 and the roller 74 move on the guide rail 73, the limit plate 475 will stably push the paper printed matter on the support plate 53 toward the external transport vehicle. The mounting plate 51 is slidably engaged with the card slot 474, so that the support plate 53 will not shake during the movement, which not only speeds up the stacking speed of the paper printed matter, but also improves the efficiency of its loading and unloading. Step three, when the paper printed matter is moved to the external transport vehicle, the paper printed matter will deviate from the top of the mobile vehicle 3 itself. Since the counterweight block 44 moves toward the lifting tooling 2, it ensures that the center of gravity of the mobile vehicle 3 is still directly above the mobile vehicle 3 itself, avoiding the mobile vehicle 3 from tipping over when stacking paper printed matter.
