Description

Technical Field

[0001] The utility model relates to garbage compression equipment, in particular to a special push-pull device for front-end garbage compression equipment. Background Art

[0002] The garbage transfer station collects and concentrates scattered household garbage, uses the garbage compression equipment in the station to compress and reduce the volume, and then loads the compressed and reduced garbage into the garbage loading equipment. In the entire garbage compression and loading process, the most critical technology is the docking and separation between the compression equipment and the loading equipment. In the docking and separation technology, a push-pull device is required to connect or separate the compression equipment and the loading equipment. The function of the push-pull device is to pull the garbage loading equipment and connect it to the garbage equipment, or to push the garbage loading equipment and separate it from the garbage compression equipment.

[0003] In practical applications, the usual horizontal garbage compactor has a push-pull device, but the push-pull stroke is limited, often less than 1m, and the front-end high-position scraper type compressor is limited by its own structure and does not have a position for welding a push-pull device. Therefore, the purpose of this utility model is to design an independent, stroke of more than 2m, safe and stable equipment operation, and can be used in garbage compactors affected by hopper pits or other terrains, garbage bins that cannot be placed in place, and insufficient push-pull strokes, so as to improve the scope of application of the equipment. The push-pull device for front-end garbage compression equipment is the purpose of this utility model. Utility Model Content

[0034] The utility model is an independent push-pull device specially designed for front-end garbage compression equipment, which cooperates with a frame 11, a push-pull assembly 2 and a driving mechanism and has a stroke of more than 2m and safe and stable operation. The push-pull device can be used in garbage compressors that are affected by hopper pits or other terrains, where garbage bins cannot be placed in place, or where the push-pull stroke is insufficient, so as to improve the scope of application of the equipment.

[0035] The push-pull device also includes push-pull limit assemblies 5 which are arranged one by one on the upper end surfaces of the corresponding guide rails 101. The vertical distance between the straight line where the push-pull limit assemblies 5 are located and the straight line where the hook groove member 3 is located is the distance between the front crossbeam and the rear roller of the trash can. The push-pull limit assemblies 5 include two push-pull limit pads which are arranged at intervals and have an isosceles trapezoidal structure in longitudinal section.

[0036] The utility model cooperates with the hook groove member 3 and the push-pull limit assembly 5 to limit and fix the front end beam and the rear end roller of the garbage bin, which can not only quickly and conveniently determine that the garbage bin is placed in place to avoid deviation; moreover, the front end beam of the garbage bin is clamped in the hook groove 301 of the hook groove member 3 to fix the garbage bin, ensuring that the garbage bin can run accurately and stably along the guide rail 101 during the subsequent pushing and pulling process.

[0038] The utility model is provided with corresponding supporting rollers 6 at the bottom of the hook groove member 3 to effectively prevent the front end of the push-pull rod 201 from sagging due to its own weight when it is extended. At the same time, the roller structure can well reduce the friction force and promote the smoothness of the push-pull action.

[0039] The receiving frame 1 also includes a retaining beam 103 and a positioning beam 102 which are fixed to the rear ends of the two guide rails 101 in sequence. The positioning beam 102 is installed at the end of the guide rail 101, and the driving cylinder 4 is installed on the receiving frame 1 through a connecting seat 104 fixed to the retaining beam 103.

[0040] The upper end surfaces of the two guide rails 101 are located at the front end of the positioning beam 102 and are provided with corresponding limit stops 7, which are arranged in an L shape and are fixed to the corresponding guide rails 101 by corresponding bolts. The limit stops 7 can be used to limit the moving distance of the trash bin.

[0041] The receiving frame 1 is located outside the front ends of the two guide rails 101, and both ends of the positioning beam 102 extending outward are fixedly connected with fixing members 8 for installing the push-pull device on the ground.

[0042] A plurality of reinforcing beams 105 arranged at intervals are connected and provided between the two guide rails 101 and below the push-pull guide rod 202 . The upper end surfaces of the reinforcing beams 105 are each recessed with a groove for clamping the push-pull guide rod 202 .

[0043] The utility model improves the stability of the connection of the guide rails 101 by arranging a reinforcing crossbeam 105 between the guide rails 101. More importantly, a groove is arranged on the upper end surface of the reinforcing crossbeam 105 for limiting the support and installing the push-pull guide rod 202, which effectively prevents the push-pull guide rod 202 from deviating during the pushing and pulling process, and can support the push-pull guide rod 202 to improve its stability.

[0044] A front end slider 203 matching the push-pull rod 201 is provided on the inner side of the front end of the push-pull guide rod 202 through corresponding bolt locking, and a rear end slider 204 matching the push-pull guide rod 202 is provided on the outer side of the tail of the push-pull rod 201 through corresponding bolt locking.

[0045] The utility model not only connects the garbage bin through the hook groove part 3, but also realizes the push-pull movement of the garbage bin by telescoping the piston rod of the driving oil cylinder 4 of the articulated hook groove part 3, and the push-pull assembly 2 symmetrically arranged on both sides of the driving oil cylinder 4 can ensure and improve the safety and stability of pushing and pulling. The push-pull assembly 2 is composed of a push-pull rod 201 and a push-pull guide rod 202 that are arranged inside and outside and slidably connected. The front end inner side of the push-pull guide rod 202 is provided with a front end slider 203 that matches the push-pull rod 201 through corresponding bolt locking, and the rear end outer side of the push-pull rod 201 is provided with a rear end slider 204 that matches the push-pull guide rod 202 through corresponding bolt locking. The matching arrangement of the slider can be used to connect the push-pull rod 201 and the push-pull guide rod 202 to prevent them from falling off when pulling and pulling, and can also improve the smoothness and stability of pulling and pulling.

[0046] The outer sides of the guide rails 101 are provided with corresponding blocking bars, and the two outer sides at the feeding end of the guide rails 101 are extended outwards and expanded.

[0047] Usage process: In the actual working process, the detachable garbage truck slowly places the garbage bin on the guide rail 101, and the rear end roller of the garbage bin contacts the guide rail 101, and the garbage bin is slowly lowered. When the rear end roller slides into the push-pull limit assembly 5, the front end beam of the garbage bin just falls into the hook groove 301 position of the hook groove part 3. At this time, the hook arm is released, and the push-pull assembly 2 is reset by the piston rod of the driving cylinder 4. The push-pull rod 201 retracts to the inside of the push-pull guide rod 202, and then pulls the garbage bin backward until the rear end roller of the garbage bin contacts the limit stopper 7. At this time, the garbage bin is put in place. When hooking the bin, the push-pull rod 201 is extended forward by the piston rod of the driving cylinder 4, and the push-pull assembly 2 slowly pushes the garbage bin out. When the rear end roller of the garbage bin enters the push-pull limit assembly 5, the hook arm can hook up the garbage bin and pull it out

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
