Description

Technical Field

[0001] This invention relates to the field of hooklift truck technology, and in particular to a method for one-step loading and unloading of two containers in a vertically placed container semi-trailer at a vertical garbage compression station, and its usage. Background Technology

[0002] The problem with existing technology is:

[0003] To reduce transportation costs, the international standard commonly uses semi-trailer flatbed trucks for container transport, with containers loaded onto semi-trailers. Currently, there are numerous vertical garbage compression stations in China. The method used is: a vertical hooklift truck is used to place the vertically placed garbage containers onto the truck, and then a gantry crane or reach stacker is used to lift the garbage containers from the hooklift truck onto the semi-trailer for transport.

[0004] The problem is:

[0005] (1) Vertical hooklift trucks can only move vertically placed garbage containers onto the truck and place them horizontally, and cannot directly unload garbage containers horizontally onto semi-trailers.

[0006] (2) It is necessary to build a gantry crane loading and unloading area or purchase a front-end crane, which increases equipment costs;

[0007] (3) Gantry crane and front crane operations are special operations, requiring professionally trained personnel to hold certificates before they can work. At the same time, there are certain safety risks involved in the work.

[0008] (4) Vertical hooklift trucks only serve the function of moving garbage containers onto the truck and unloading materials. Their functionality is relatively weak, and their cost is generally higher than that of ordinary hooklift trucks. They also have limited functionality and weak versatility. Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vertical and horizontal two-way low-position loading and unloading box-type hook device and its usage method, so as to realize the loading of vertical boxes onto the vehicle and the horizontal placement of boxes onto the semi-trailer, making one vehicle multi-purpose.

[0010] The objective of this invention is achieved as follows:

[0011] A vertical and horizontal dual-direction low-position loading and unloading box-type hook device includes a base, which is used to be fixedly installed longitudinally on a Class II automobile chassis.

[0012] A tilting frame cylinder support is fixed at the front end of the base, and a tilting arm is hinged to the rear end of the base. A rotating arm is hinged to the middle of the tilting arm via a rotating arm shaft. A switchable connection structure is provided between the tilting arm and the rotating arm. One end of the tilting frame cylinder is hinged to the tilting frame cylinder support, and the other end of the tilting frame cylinder is hinged to the rotating arm via the tilting frame cylinder shaft. The tilting frame cylinder is used to drive the rotating arm to rotate. A hook arm is hinged to the end of the rotating arm. A hook arm cylinder is hinged between the rotating arm and the hook arm. The hook arm cylinder is used to drive the hook arm to rotate. A hook body is provided at the end of the hook arm. Box guide rollers are provided on both sides of the tilting arm. The box guide rollers are used to provide rolling support for one end of the bottom longitudinal beam of the garbage box. The hook body is used to hook the hook ring at the bottom of the other end of the garbage box.

[0013] Preferably, the base has two base longitudinal beams, and the two base longitudinal beams are connected to multiple crossbeams. The tilting frame cylinder support is connected between the two base longitudinal beams. Each base longitudinal beam is provided with a box body longitudinal beam bearing roller and a box body longitudinal beam support. The box body longitudinal beam bearing roller is used to provide rolling support for the garbage box body longitudinal beam. The box body longitudinal beam support is located in front of the box body longitudinal beam bearing roller and is higher than the box body longitudinal beam bearing roller. The box body longitudinal beam support is used to provide fixed support for the two longitudinal beams of the garbage box body.

[0014] Preferably, the rotating arm has a groove along its longitudinal direction, and in the connected state, the rotating arm is positioned within the groove.

[0015] Preferably, hinged arms are fixed on both sides of the rotating arm, one end of the hinged arm is connected to the cylinder shaft of the tilting frame, and the other end of the hinged arm is connected to the rotating arm shaft.

[0016] Preferably, the connection structure includes a locking slot on the flip arm and a locking latch on the rotating arm.

[0017] Preferably, the container guide roller is mounted on the guide roller steering arm, which is hinged to the tilting arm. A container guide roller lifting cylinder is provided between the guide roller steering arm and the tilting arm. The container guide roller lifting cylinder is used to drive the container guide roller to lift and lower through the guide roller steering arm, and in conjunction with the rotation of the hook body driven by the hook arm, thereby changing the lifting height of the garbage container to adapt to semi-trailers of different heights.

[0018] Preferably, the tilting arm is equipped with a longitudinal beam clamp for the container, and the garbage container is provided with a clamp locking plate. When transporting or dumping garbage, the longitudinal beam clamp for the container is connected and fixed to the clamp locking plate to lock the garbage container.

[0019] A method for using a vertical and horizontal dual-direction low-position loading and unloading box-type hook device.

[0020] The process of loading the garbage bin onto the vehicle:

[0021] When the garbage bin is placed close to the vertically positioned body, the connection structure is in the connected state, locking the tipping arm and rotating arm together. The hook arm cylinder retracts, and the tipping frame cylinder extends, causing the hook to hook the hook ring. The hook arm cylinder drives the hook arm to extend, and the guide rollers of the garbage bin support the bottom longitudinal beam of the garbage bin, hooking the garbage bin off the ground. The tipping frame cylinder retracts, placing the garbage bin horizontally on the base.

[0022] The process of emptying the trash can:

[0023] With the garbage container placed horizontally on the base, the tilting arm and rotating arm are locked together, the tilting frame cylinder extends, the hook arm cylinder extends, the tilting arm and rotating arm tilt together, and the rear door of the garbage container opens to dump the garbage.

[0024] The process of placing the garbage bin onto the semi-trailer:

[0025] With the garbage container placed horizontally on the base, unlock the connection structure of the rotating arm and the tipping arm. The tipping arm remains in a horizontal position, the hook arm cylinder retracts, and the tipping frame cylinder extends, driving the rotating arm to rotate around the rotating arm axis, thus placing the garbage container onto the semi-trailer.

[0026] Preferably, a semi-trailer with two containers is used to transfer the garbage containers.

[0027] Preferably, when placing the garbage bin, the garbage bin is placed vertically on the ground or horizontally on the semi-trailer.

[0028] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0029] 1. The vertically placed garbage bins are directly hooked onto the truck and placed horizontally. The hook arm principle is used to place the bins onto the semi-trailer at a low position, which improves loading and unloading efficiency and reduces equipment investment. For the technical transformation of existing hook arm trucks, only the upper body needs to be replaced. The high-value truck chassis is retained, reducing the technical transformation cost.

[0030] 2. Without the need for a gantry crane, a front-end crane can easily place garbage containers onto semi-trailers, greatly saving on equipment investment and site construction costs;

[0031] 3. The garbage container-mounted semi-trailer is more flexible and maneuverable, and the hook-lift truck can place the garbage container onto the semi-trailer at any location;

[0032] 4. For semi-trailers whose height is higher than the rear rollers of the hooklift truck, there is no need for a rear wheel lift platform or to prepare rear wheel lift platforms of different specifications. The system automatically raises to the appropriate height based on the specific semi-trailer, significantly reducing the labor intensity of operators.

[0033] 5. Enhanced safety: After raising the garbage container, the hooklift truck smoothly approaches the semi-trailer to a safe distance on level ground;

[0034] 6. Significantly reduce waste transfer costs. (1) Using a semi-trailer with two boxes for transfer, the loading capacity is large, and one truck is equivalent to the transport capacity of two hooklift trucks; (2) The purchase cost of a semi-trailer flatbed truck plus a tractor is lower than the cost of a hooklift truck; (3) The work of two people can be completed by one person, which greatly reduces labor and logistics costs.

Detailed Implementation

[0039] See Figure 1 This is an embodiment of a vertical and horizontal two-way low-position loading and unloading box-type hook device, which includes a base 1 for longitudinally fixing on a Class II automobile chassis.

[0040] A tilting frame cylinder support 20 is fixed to the front end of the base 1, and a tilting arm 8 is hinged to the rear end of the base 1. A rotating arm 12 is hinged to the middle of the tilting arm 8 via a rotating arm shaft 9. A switchable connection structure is provided between the tilting arm 8 and the rotating arm 12. The connection structure includes a locking slot 18 on the tilting arm 8 and a locking latch on the rotating arm 12. A groove is provided along the longitudinal direction on the tilting arm 8. In the connected state, the rotating arm 12 is positioned within the groove. One end of the tilting frame cylinder 2 is hinged to the tilting frame cylinder support 20, and the other end of the tilting frame cylinder 2 is hinged to the rotating arm 12 through the tilting frame cylinder shaft 10. The tilting frame cylinder 2 is used to drive the rotating arm 12 to rotate. A hook arm 15 is hinged to the end of the rotating arm 12. A hook arm cylinder 13 is hinged between the rotating arm 12 and the hook arm 15. The hook arm cylinder 13 is used to drive the hook arm 15 to rotate. A hook body 17 is provided at the end of the hook arm 15. Box guide rollers 6 are provided on both sides of the tilting arm 8. The box guide rollers 6 are used to provide rolling support for one end of the bottom longitudinal beam 25 of the garbage box. The hook body 17 is used to hook the hook ring 26 at the bottom of the other end of the garbage box.

[0041] The base 1 has two base longitudinal beams, and the two base longitudinal beams are connected to multiple crossbeams. The tilting frame cylinder support 20 is connected between the two base longitudinal beams. Each base longitudinal beam is provided with a box body longitudinal beam bearing roller 3 and a box body longitudinal beam support 21. The box body longitudinal beam bearing roller 3 is used to provide rolling support for the garbage box longitudinal beam. The box body longitudinal beam support 21 is located in front of the box body longitudinal beam bearing roller 3 and is higher than the box body longitudinal beam bearing roller 3. The box body longitudinal beam support 21 is used to provide fixed support for the two longitudinal beams of the garbage box.

[0042] Hinged arms are fixed on both sides of the rotating arm 12. One end of the hinged arm is connected to the tilting frame cylinder shaft 10, and the other end of the hinged arm is connected to the rotating arm shaft 9.

[0043] The container guide roller 6 is mounted on the guide roller steering arm 5, which is hinged to the tilting arm 8. A container guide roller lifting cylinder 4 is provided between the guide roller steering arm 5 and the tilting arm 8. The container guide roller lifting cylinder 4 is used to drive the container guide roller 6 to lift and lower through the guide roller steering arm 5. In conjunction with the rotation of the hook body 17 driven by the hook arm 15, the lifting height of the garbage container is changed to adapt to semi-trailers of different heights.

[0044] The tilting arm 8 is equipped with a box body longitudinal beam clamp 7, and the garbage container 23 is equipped with a clamp lock plate 24. When transporting and dumping garbage, the box body longitudinal beam clamp 7 is connected and fixed with the clamp lock plate 24 to lock the garbage container 23.

[0045] How to use a vertical and horizontal dual-direction low-position loading and unloading box-type hook device:

[0046] The process of loading the garbage bin onto the vehicle:

[0047] When the garbage bin is placed close to the vertically positioned body, the connection structure is in the connected state, locking the tipping arm 8 and the rotating arm 12. The hook arm cylinder 13 retracts, and the tipping frame cylinder 2 extends, causing the hook body 17 to hook the hook ring 26. The hook arm cylinder 13 drives the hook arm 15 to extend, and the bin guide roller 6 supports the bottom longitudinal beam 25 of the garbage bin 23, hooking the garbage bin off the ground 22. The tipping frame cylinder 2 retracts, placing the garbage bin horizontally on the base 1.

[0048] The process of emptying the trash can:

[0049] With the garbage container horizontally placed on the base 1, the tilting arm 8 and the rotating arm 12 are locked together, the tilting frame cylinder 2 extends, the hook arm cylinder 13 extends, the tilting arm 8 and the rotating arm 12 tilt together, and the rear door of the garbage container opens to dump the garbage.

[0050] The process of placing the garbage bin onto the semi-trailer:

[0051] With the garbage container horizontally placed on the base 1, the connection structure between the rotating arm 12 and the tipping arm 8 is unlocked. The tipping arm 8 remains in a horizontal position, the hook arm cylinder 13 retracts, and the tipping frame cylinder 2 extends, causing the rotating arm 12 to rotate around the rotating arm shaft 9, thus placing the garbage container onto the semi-trailer. In this embodiment, a semi-trailer with two containers is used to transport the garbage container.

[0052] When placing the garbage container, position it vertically on the ground (22) or horizontally on the semi-trailer. The process of placing the container on the ground is the reverse of the process of loading the garbage container onto the truck.

[0053] This invention allows the tilt of the garbage container during loading and unloading to be adjusted via a switch on the connecting device, thus adapting to different work requirements. It enables the garbage container to be loaded onto a truck using a hooklift truck as usual, and also allows it to be smoothly placed onto a semi-trailer. The tilt of the garbage container during loading and unloading can also be adjusted by the extension and retraction of the hooklift arm via the hooklift arm cylinder 13, further adapting to work requirements. Moreover, the loading of the garbage container via the hooklift arm cylinder 13 relies primarily on the weight of the garbage container, allowing for normal extension and minimizing energy consumption.

[0054] The working method of the present invention will now be described with reference to the accompanying drawings:

[0055] The hooklift truck approaches the vertically placed garbage container, such as... Figure 2 As shown, the hook body 17 hooks the hook ring 26, the hook arm cylinder 13 drives the hook arm 15 to rotate upward, and the box guide roller 6 supports the bottom longitudinal beam 25, hooking the garbage box body off the ground 22, as shown. Figure 3 As shown, the tilting frame cylinder 2 then retracts, and the garbage container falls horizontally onto the vehicle, as... Figure 4 As shown.

[0056] When emptying the trash can, the trash is like... Figure 5 As shown.

[0057] Place the garbage bin onto the semi-trailer, such as Figure 6 As shown.

[0058] The trash can is in Figure 4 When in the state, the locking latch 18 disengages from the locking latch 19. At this time, when the retractable tilting frame cylinder 2 is extended again, the tilting arm 8 remains stationary and is in a horizontal position. The rotating arm 12 rotates around the rotating arm shaft 9, as shown in the figure, to place the garbage container onto the semi-trailer. Figure 7 This shows the garbage bin being placed on the semi-trailer.

[0059] When the semi-trailer is high enough, the guide rollers 6 can be raised to lift the garbage container, thus placing it onto the semi-trailer. Figure 8 As shown.

[0060] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
