Description

Technical Field

[0001] This utility model relates to the field of excavator technology, and in particular to a tooling for hoisting a boom. Background Technology

[0002] The boom and stick are working devices of an excavator, also commonly called the boom and arm. Their main function is to control the digging and loading actions of the bucket. During the production of the excavator's stick, it is necessary to hoist the stick.

[0003] A search revealed a Chinese patent (application number "201921654444.1") that discloses "a lifting device for lifting excavator booms." This device includes a boom body with a first connecting hole and a second connecting hole on its surface. Two connecting ribs are fixedly connected to the upper surface of the boom body, and a support plate is fixedly installed between the two ribs. However, during use, because the boom is off-center, it is prone to shifting under gravity during lifting, causing it to collide and resulting in low practicality. Utility Model Content

[0004] This utility model provides a tooling for hoisting a boom, which solves the problem in the prior art where the boom is easily displaced under gravity during hoisting, causing it to collide and resulting in low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tooling for hoisting a boom includes an installation mechanism disposed on the upper part of the boom. The installation mechanism includes a mounting base, a triangular connecting block, and an abutment plate fixed to one outer wall of the bottom of the mounting base. The mounting base is provided with two suspension components. Connecting components are provided on both sides of the bottom of the mounting base. Each connecting component includes a mounting plate fixed to the outer wall of the bottom of the mounting base, a cylinder bolted to one outer wall of the mounting plate, and a locking post fixed to one outer wall of the piston rod of the cylinder. An adjustment component is provided at the bottom of the mounting base. The adjustment component includes a first fixing plate fixed to the outer wall of the bottom of the mounting base, a second fixing plate fixed to the outer wall of the bottom of the mounting base, and a bidirectional screw connected to one outer wall of the second fixing plate via a bearing. The bidirectional screw is provided with two support components. Each support component includes a connecting plate screwed to one outer wall of the bidirectional screw and a limiting post sleeved on the inner wall of a through hole at one end of the boom.

[0007] Preferably, the connecting block is fixed on the bottom outer wall of the mounting base, and the mounting base is sleeved on the upper inner wall of the boom, with the bottom of the abutting plate abutting against the top outer wall of the boom.

[0008] Preferably, the suspension assembly includes two ear plates respectively fixed to the outer walls of the top of the mounting base and a connecting rod with both ends passing through and inserted into the outer wall of one side of the two ear plates.

[0009] Preferably, two triangular plates are fixed on one outer wall of the mounting plate, and the two triangular plates are respectively fixed on the bottom outer wall of the mounting base, and one end of the snap-fit ​​post is slidably sleeved in the through hole at the top of the stick.

[0010] The above scheme uses the movement of two cylinder piston rods to drive the locking pin to move, thereby locking the locking pin into the through hole of the upper connecting structure of the stick, thus connecting the connecting block and the upper connecting structure of the stick.

[0011] Preferably, reinforcing plates are fixed on the outer walls of the first and second fixing plates on opposite sides, and four reinforcing plates are respectively fixed on the bottom outer wall of the mounting base. One end of the bidirectional screw passes through and is connected to the outer wall of the first fixing plate through a bearing. Two limiting rods are fixed on the outer walls of the first and second fixing plates on opposite sides.

[0012] Preferably, the connecting plate is slidably mounted on the outer walls of the two limiting rods, and the limiting post is fixed on one side of the outer wall of the connecting plate.

[0013] The above scheme involves rotating a bidirectional screw to move two connecting plates, which then move along two limiting rods, thereby allowing the two limiting posts to be fitted into the through holes at the bottom of the boom, thus supporting the boom.

[0014] The beneficial effects of this utility model are as follows:

[0015] The movement of the piston rods of the two cylinders drives the locking pins to move, which in turn locks the locking pins into the through holes of the upper connecting structure of the boom, thus connecting the connecting block and the upper connecting structure of the boom. Rotating the bidirectional screw drives the two connecting plates to move. The connecting plates move along the two limiting rods, which in turn causes the two limiting pins to be fitted into the through holes of the lower part of the boom, thus supporting the boom. This can support the boom during hoisting, preventing the boom from deflecting and colliding under the action of gravity, thus improving its practicality. Attached Figure Description
