Description

Technical Field

[0001] The utility model relates to the field of waste treatment, in particular to a box grabbing mechanism for a material loading box. Background Art

[0002] Garbage is solid waste generated in daily life and production. Due to its large volume, complex and diverse composition, and polluting, resource-intensive, and socially oriented nature, it requires harmless treatment, resource utilization, and volume reduction. Failure to properly handle it pollutes the environment, impacts sanitation, wastes resources, disrupts production and living safety, and undermines social harmony. Garbage disposal is the process of rapidly removing and harmlessly treating garbage, followed by its proper utilization. Currently, sanitary landfill, high-temperature composting, and incineration are widely used methods. The goals of garbage disposal are harmless treatment, resource utilization, and volume reduction.

[0003] Garbage will be sent to the garbage treatment station for processing by transport vehicles. The transport vehicles include dump garbage trucks and semi-trailer transport vehicles. The semi-trailer transport vehicle consists of a semi-trailer and a material loading box. Since there is no hydraulic lifting mechanism on the semi-trailer, for dump garbage trucks and semi-trailer transport vehicles with the same rated load capacity, the material loading box in the semi-trailer transport vehicle can carry more garbage.

[0004] When receiving or unloading garbage, the material loading box needs to be rotated at an angle to tilt it. In this case, a tilting frame is generally used to drive the material loading box to rotate or tilt. Therefore, before tilting, the material loading box needs to be connected to the tilting frame. The tilting frame consists of a tilting bracket and an angle lock installed on the tilting bracket. When the material loading box moves above the tilting bracket (the material loading box is above the tilting bracket when loading garbage) or below the tilting bracket (the material loading box is below the tilting bracket when unloading garbage), the angle lock engages with the lock hole at the corner of the material loading box, and then the angle lock and the material loading box are connected. When the tilting bracket flips, it can drive the material loading box to tilt.

[0005] When the material loading box is moved under the tilting frame, the semi-trailer body is generally used to drive the material loading box to move in a reverse manner. Since the reverse path is not exactly the same each time and the position of the tilting frame is fixed, there is a high probability that the corner lock will not correspond to the lock hole on the material loading box, resulting in the corner lock not being able to enter the lock hole smoothly or being unable to enter the lock hole, thereby making it impossible to connect the material loading box and the tilting frame. Utility Model Content

[0006] The utility model provides a box grabbing mechanism for a material loading box. The utility model can adjust a corner lock to a position corresponding to a lock hole on the material loading box.

[0007] The box grabbing mechanism of the material loading box includes a flip frame, which consists of a flip frame and an angle lock installed on the flip frame. The flip frame is provided with a accommodating cavity, and the angle lock cooperates with the accommodating cavity. The angle lock includes a first linear drive, a connecting rod, a first swing arm, a locking component, and a fixed sleeve. One end of the connecting rod is connected to the power output end of the first linear drive, and one end of the first swing arm is connected to the other end of the connecting rod. The locking component includes a rotating shaft and a lock head. One end of the rotating shaft is connected to the other end of the first swing arm, the rotating shaft passes through the fixed sleeve, and the other end of the rotating shaft is connected to the lock head. It also includes a movable seat and a second linear drive. The movable seat cooperates with the accommodating cavity. The first linear drive, the second linear drive and the fixed sleeve are respectively fixed to the movable seat, and the power output end of the second linear drive is connected to the flip frame.

[0008] Furthermore, the flip bracket is provided with a clearance opening for providing clearance space for the rotating shaft or the lock head when the rotating shaft or the lock head moves, and the rotating shaft or the lock head passes through the clearance opening.

[0009] Furthermore, the flip bracket includes a bracket body and a support tube. Both ends of the bracket body are fixed with support tubes for connection. The accommodating cavity is an inner hole on the support tube, and the clearance port is provided on the support tube.

[0010] Furthermore, the flip bracket is provided with a clearance opening for providing clearance space for the lock head when it moves, and the lock head passes through the clearance opening.

[0011] Furthermore, the angle lock also includes a limit block, the limit block cooperates with the clearance opening, the limit block is fixed to the movable seat, and the rotating shaft passes through the limit block.

[0012] When a semi-trailer carrying a material loading box is reversed to the bottom of the flip bracket, if the lock head does not correspond to the lock hole on the material loading box, the left and right positions of the angle lock are adjusted by the second linear drive. The specific adjustment process is: when the piston rod of the second linear drive is extended, since the support tube and the connecting seat are in a fixed state, the second linear drive drives the movable seat to move from right to left, thereby moving the angle lock as a whole from right to left. When the piston rod of the second linear drive is retracted, since the support tube and the connecting seat are in a fixed state, the second linear drive drives the movable seat to move from left to right, thereby moving the angle lock as a whole from left to right. According to the specific situation on site, one of the above two speed regulation conditions is selected for adjustment, so that the lock head corresponds to the lock hole on the material loading box, and finally the purpose of connecting the box grabbing mechanism with the material loading box is achieved.

[0020] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0021] like Figures 1 to 4 The grabbing mechanism for a material loading box of the present invention includes a tilting frame, which comprises a tilting bracket 1 and a corner lock 2 mounted on the tilting bracket 1. The tilting bracket 1 is provided with a receiving cavity 10. The tilting bracket 1 includes a bracket body 12 and a support tube 13. The support tubes 13 are fixed at both ends of the bracket body 12 and connected. The receiving cavity 10 is the inner hole of the support tube 13. The tilting bracket 1 is also mounted with a door opening mechanism 15 for the tailgate of the material loading box. The structure of the door opening mechanism 15 is conventional and will not be described in detail here.

[0022] The bracket body 12 is hingedly connected to the lower bracket 5 via a hinged component. A first hydraulic cylinder 6 is mounted on the lower bracket 5 and is connected to the tilt bracket 1. When the first hydraulic cylinder 6 is in operation, the tilt bracket 1 rotates about the hinged portion between the tilt bracket 1 and the lower bracket 5. The lower bracket 5 can be a fixed bracket or a movable bracket. In this embodiment, the lower bracket 5 is preferably a movable bracket, which adopts a planar rod mechanism structure, such as an articulated four-bar mechanism. The movable lower bracket 5 is connected to a second hydraulic cylinder 7, which drives the lower bracket 5 to form a folded state or an unfolded state. There are two lower brackets 5, and a parking space for vehicles (such as semi-trailers) to enter and exit is formed between the two lower brackets 5.

[0023] The angle lock 2 cooperates with the accommodating cavity 10. The angle lock 2 includes a first linear drive 20, a connecting rod 21, a first swing arm 22, a locking component, and a fixing sleeve 23. The first linear drive 20 preferably adopts a double-rod piston cylinder. The two piston rods of the double-rod piston cylinder are respectively connected to a connecting rod 21. In this way, the connecting rod 21, the first swing arm 22, the locking component, and the fixing sleeve 23 are symmetrically arranged at both ends of the first linear drive 20.

[0024] The first linear drive 20 can be an air cylinder, a hydraulic cylinder, etc. One end of the connecting rod 21 is connected to the power output end of the first linear drive 20, and the connecting rod 21 is hinged to the power output end of the first linear drive 20. One end of the first swing arm 22 is connected to the other end of the connecting rod 21, and one end of the first swing arm 22 is fixedly connected to the other end of the connecting rod 21.

[0025] The locking component includes a rotating shaft 24 and a lock head 25. One end of the rotating shaft 24 is connected to the other end of the first swing arm 22. The first swing arm 22 is fixed to the rotating shaft 24. The rotating shaft 24 passes through the fixed sleeve 23. The fixed sleeve 23 is composed of a connecting sleeve and a bearing. The bearing is fixed to the fixed sleeve 23. The rotating shaft 24 passes through the bearing and is fixed to the bearing. The other end of the rotating shaft 24 is connected to the lock head 25. The circumferential surface of the lock head 25 is composed of a rectangular surface and an arc surface. The rectangular surface and the arc surface are alternately connected. The end face of one end of the lock head 25 is a conical surface.

[0026] The present invention further includes a movable base 3 and a second linear actuator 4. The movable base 3 engages with the accommodating chamber 10 and slides with the support tube 13. The first linear actuator 20, the second linear actuator 4, and the fixing sleeve 23 are respectively fixed to the movable base 3. The second linear actuator 4 can be a pneumatic cylinder, a hydraulic cylinder, an electric linear module, or the like. The power output end of the second linear actuator 4 is connected to the tilt bracket 1. The accommodating chamber 10 includes a connecting base 14 fixed to the support tube 13. The power output end of the second linear actuator 4 is connected to the connecting base 14.

[0027] When a semi-trailer carrying a material loading box reverses under the flip bracket 1, if the lock head 25 does not correspond to the lock hole on the material loading box, the left and right positions of the angle lock 2 are adjusted by the second linear actuator 4. The specific adjustment process is as follows: when the piston rod of the second linear actuator 4 is extended, since the support tube 13 and the connecting seat 14 are in a fixed state, the second linear actuator 4 drives the movable seat 3 to move from right to left, thereby causing the entire angle lock 2 to move from right to left. When the piston rod of the second linear actuator 4 is retracted, since the support tube 13 and the connecting seat 14 are in a fixed state, the second linear actuator 4 drives the movable seat 3 to move from left to right, thereby causing the entire angle lock 2 to move from left to right. Depending on the specific situation on site, one of the two speed adjustment conditions mentioned above is selected for adjustment so that the lock head 25 corresponds to the lock hole on the material loading box, ultimately achieving the purpose of connecting the box grabbing mechanism to the material loading box.

[0028] The flip bracket 1 is provided with a clearance opening 11 to provide clearance space for the rotating shaft 24 or the lock head 25 when moving. The clearance opening 11 is set on the support tube 13, and the rotating shaft 24 or the lock head 25 passes through the clearance opening 11. When the second linear drive 4 drives the position of the angle lock 2, the rotating shaft 24 or the lock head 25 can avoid interference with the support tube 13.

[0029] The angle lock 2 also includes a stopper 26, which engages with the clearance opening 11 and is fixed to the movable base 3. The rotating shaft 24 passes through the stopper 26. When the second linear actuator 4 drives the movable base 3 to move, the stopper 26 contacts the wall 11a of the clearance opening 11, reaching the maximum adjustment position.

[0030] The above disclosure is only a preferred embodiment of the present application, and it is certainly not intended to limit the scope of rights of the present invention. A person skilled in the art can understand that all or part of the structures of the above embodiment can be implemented and equivalent changes made in accordance with the claims of the present application are still within the scope of the application.
