Description

A tool for removing the pin shaft of a grab bucket of a garbage crane

technical field

The utility model relates to the technical field of pin shaft removal, in particular to a pin shaft removal tool for a garbage crane grab bucket.

Background technique

The grab bucket of the garbage crane is mainly used to transfer garbage. Since the garbage contains various substances, it has a greater impact on the claws and fixed pins on the garbage crane grab. The fixed pins are prone to rust inside the claws. If it is jammed, the pin shaft needs to be disassembled regularly for cleaning or maintenance.

Because the working environment of the garbage crane grab is very harsh, the fixed pin shaft of the claw flap is easy to rust and jam. When the claw flap needs to be removed, it often takes a lot of time to remove the fixed pin shaft first. The location space is narrow, and conventional pullers and hydraulic jacks cannot be used because they cannot stand, which brings a lot of inconvenience to the disassembly work. When it is necessary, it is necessary to use a cutter for destructive demolition, which consumes a lot of manpower, material resources and time.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-4, the utility model discloses a tool for removing the pin shaft of the grab bucket of the garbage crane, which includes a garbage crane claw valve 1, and the interior of the garbage crane claw valve 1 is movably connected with a pin shaft body 7, and the pin shaft body 7 The diameter is 100 mm, and the length is 290 mm. The top of the garbage hanging claw 1 is movably connected with a spacer 2. The spacer 2 is composed of two semicircles, and the thickness of the spacer 2 is the same as that of the sleeve 3. Similarly, a plurality of pads 2 can be provided. After the accumulation of multiple pads 2, the distance between the bottom of the sleeve 3 and the garbage hanging claw 1 can be increased. Let the bearing pin body 7 have enough space to move inside the spacer 2 and the sleeve 3, the thickness of the spacer 2 is 20 millimeters, the top of the spacer 2 is movably connected with the sleeve 3, and the outer diameter of the sleeve 3 is 134 mm, the inner diameter of the sleeve 3 is 122 mm, the height of the sleeve 3 is 75 mm, the top of the sleeve 3 is provided with a hollow hydraulic jack 4, and the outer diameter of the hollow hydraulic jack 4 120 mm, center hole diameter 34 mm, stroke 50 mm, tonnage 30 tons, the model of hollow hydraulic jack 4 is RCH-3050, and the model of supporting manual hydraulic pump is CP-700-2, hollow hydraulic jack The piston top of 4 is movably connected with a stopper 5, the top of the stopper 5 runs through a top screw bolt 6, the top of the pin shaft body 7 is fixedly connected with a nut 8, the inner wall of the nut 8 is threadedly connected with the surface of the top screw bolt 6, and the nut 8 is fixedly connected with the top of the pin body 7 by welding.

Specifically, the hollow hydraulic jack 4 is fixedly connected to the sleeve 3 through screws.

In this embodiment, if the hollow hydraulic jack 4 is fixedly connected with the sleeve 3 by screws, the hollow hydraulic jack 4 is fixed by the mounting seat and the sleeve 3 when the force is applied, and the hollow hydraulic jack 4 can be used when in use. more solid.

Specifically, the central axes of the garbage lifting claw 1, the spacer 2, the sleeve 3, the hollow hydraulic jack 4 and the jacking bolt 6 are all coincident.

In this embodiment, if the central axes of the garbage lifting claw 1, pad 2, sleeve 3, hollow hydraulic jack 4 and jack screw bolt 6 all coincide, the piston of the hollow hydraulic jack 4 will drive the stopper during use. After 5 moves upwards, it can vertically drive the top screw bolt 6 to move upwards, and the top screw bolt 6 can drive the pin shaft body 7 to move vertically upward through the nut 8, so that not only can the pin shaft body 7 be moved up smoothly when in use. Secondly, the whole body is not easy to shake when in use.

Specifically, a magnetic block 9 is inlaid inside the cushion block 2 .

In this embodiment, if the inside of the pad 2 is embedded with a magnetic block 9, the two pads 2 can be adsorbed together by the magnetic block 9, and the pad 2 after being adsorbed by the magnetic block 9 can be used more easily. Stablize.

The working principle and application process of the utility model: when in use, the sleeve 3 and the hollow hydraulic jack 4 are fixedly connected by bolts, the nut 8 is welded on the top of the pin body 7, and the sleeve 3 is placed on the garbage lifting claw 1, place the stopper 5 at the top piston of the hollow hydraulic jack 4, pass the top screw bolt 6 through the stopper 5 and screw the top screw bolt 6 on the nut 8, and connect the hollow hydraulic jack 4 with the external oil pump , start the hollow hydraulic jack 4, at this time the piston of the hollow hydraulic jack 4 pushes out upwards, the piston at the top of the hollow hydraulic jack 4 will withstand the stopper 5, and the stopper 5 will be blocked by the head of the jack screw bolt 6, and The nut 8 is welded together with the pin body 7, and the diameter of the sleeve 3 is larger than that of the pin body 7. When the piston moves, the piston of the hollow hydraulic jack 4 will drive the pin through the jack screw 6 and the nut 8. The shaft body 7 moves upwards, so the hollow hydraulic jack 4 and the sleeve 3 will be fixed between the stopper 5 and the garbage lifting claw 1 due to the lift force generated by themselves, forming a fixation by itself, and continuing to use the manual oil pump to make the hollow hydraulic jack 4 The piston continues to move, and when its active force is greater than the resistance of the pin body 7, the pin body 7 will be taken out by the jackscrew bolt 6, and the piston of the hollow hydraulic jack 4 reaches the maximum stroke of 50 millimeters while the pin body 7 has not yet reached the maximum stroke. At this time, the top screw bolt 6 can be unscrewed, the piston of the hollow hydraulic jack 4 is reset, and then the pad 2 is placed on the bottom of the sleeve 3, and it is located on the top of the garbage lifting claw 1, and the two pads 2. Adsorption and fixation by the magnetic block 9, screw the top screw bolt 6 on the nut 8, and then continue to push out the piston of the hollow hydraulic jack 4, and reciprocate in this way until the pin shaft is pulled out.
