DETAILED DESCRIPTION

[0018] The specific implementation modes of the present invention are described in detail below with reference to the accompanying drawings.

[0019] Reference Figure 1-Figure 3 The present invention provides a hydraulic lifting light-duty boom, including a bearing seat 1, a boom main part 2 is connected to the top of the bearing seat 1, a hydraulic mechanism 3 is arranged inside the bearing seat 1, the bearing seat 1 and the hydraulic mechanism 3 are both supported and installed on the ground, the boom main part 2 is composed of a rod body, a rod tail 22, and a rod head 23, the rod head 23 carries a lifting device, the rod body is composed of a plurality of unit steel frames 21, the bottom ends of the side walls of the plurality of unit steel frames 21 are fixedly connected with a connecting block 4, the output end of the hydraulic mechanism 3 passes through the top of the bearing seat 1 and connects The block 4 is docked, and the hydraulic mechanism 3 is used to lift the pole body, and the unit steel frame 21 is added to achieve the jacking effect of the main part 2 of the pole holding rod; a circular opening is opened on the top of the load-bearing seat 1, and the pole tail 22 is conical, and its bottom end passes through the circular opening and is suspended and connected inside the load-bearing seat 1 through a number of load-bearing steel ropes 6. A number of pull ropes 8 are fixedly connected to the side of the pole tail 22, and the other ends of the pull ropes 8 are pulled by a winch. The pull ropes 8 cooperate with the winch to pull the top end of the side of the pole tail 22 to achieve angle stability and angle adjustment of the pole tail 22.

[0020] The main part 2 of the holding pole is supported on the ground by the load-bearing seat 1. When the main part 2 of the holding pole is lifted, the pole body and the pole tail 22 are disconnected. At this time, the support for the main part 2 of the holding pole is transferred from the load-bearing seat 1 to the hydraulic mechanism 3, and the output of the hydraulic mechanism 3 drives the entire pole body to be lifted. After that, a new unit steel frame 21 is added between the pole body and the pole tail 22, and the added unit steel frame 21 is connected to the pole body and the pole tail 22, so that the supporting effect of the hydraulic mechanism 3 is transferred to the load-bearing seat 1 again, and the hydraulic mechanism 3 is controlled to retract and disconnected from the connecting block 4 on the unit steel frame 21. When the hydraulic mechanism 3 retracts to the initial state, its output The end is connected to the connecting block 4 on the newly added unit steel frame 21, and the reciprocating operation of the holding pole main part 2 can be achieved, and the pole tail 22 is connected to the load-bearing seat 1 through a number of load-bearing steel ropes 6. Since the pole tail 22 lacks stability in the suspended state, the angle of the pole tail 22 can be changed. Through a number of pull ropes 8 and a winch device, the side of the pole tail 22 is pulled and tightened to stabilize the angle. Through a number of winches, the winding length of different pull ropes 8 can be controlled to fix the pole tail 22 at any angle position to achieve the angle adjustment effect. Through the angle change of the pole tail 22, the inclination angle of the holding pole main part 2 can be accurately adjusted.

[0021] Reference Figure 3 A plurality of pulleys 7 are fixedly connected to the side of the load-bearing seat 1, and a plurality of pull ropes 8 are respectively passed around the plurality of pulleys 7 and connected to the hoisting equipment; an inclination sensor 5 is fixedly installed on the inner wall of the rod tail 22.

[0022] The pulley 7 can be provided to avoid friction loss caused by contact between the pull rope 8 and the load-bearing seat 1, and the precise angle value of the rod tail 22 can be grasped by the inclination sensor 5.

[0023] Reference Figure 4 , 5 The hydraulic mechanism 3 is composed of four hydraulic cylinders 31, and is distributed at the four corners inside the load-bearing seat 1. The output end of the hydraulic cylinder 31 passes through the top of the load-bearing seat 1 and is connected to a connector 32. The connector 32 is docked with the connecting block 4. The connector 32 includes a U-shaped joint 321. The inner wall of the top of the U-shaped joint 321 is fixedly connected to a fixed shaft 322. The side wall of the fixed shaft 322 is movably sleeved with a flip plate 323. The bottom of the flip plate 323 is an inclined slope, and its inclined slope is supported by a load-bearing pad 325. The flip plate 323 is transmission-connected to the inner wall of the U-shaped joint 321 through a torsion spring 326. The top of the flip plate 323 is fixedly connected to a pin 324. A notch is provided at the bottom of the connecting block 4, and the pin 324 is inserted into the notch for combined connection.

[0024] After the hydraulic mechanism 3 lifts the rod body and adds it to the new unit steel frame 21, the hydraulic mechanism 3 needs to be disconnected from the connecting block 4. By adopting a combination method in which the pin 324 is inserted into the slot from the bottom of the connecting block 4, the hydraulic cylinder 31 can automatically complete the disconnection after it is retracted, making the device more convenient to use. After the hydraulic mechanism 3 is retracted, it needs to be reconnected with the connecting block 4 on the newly added unit steel frame 21 to carry out the next stage of lifting action. By combining the combination of the pin 324 and the insertion method at the bottom of the connecting block 4, the top of the connecting block 4 will block the flip plate 323 during the retraction of the hydraulic cylinder 31, thereby setting the flip plate 323 to a flip type. When the bottom of the flip plate 323 contacts the connecting block 4, the flip plate 323 receives an upward force to flip along the axis of the fixed shaft 322, thereby achieving the effect of bypassing the connecting block 4. When the connector 32 reaches the bottom of the connecting block 4, the flip plate 323 is flipped and reset by the torsion of the torsion spring 326, and the flip angle of the flip plate 323 is limited by the load-bearing pad 325.

[0025] Reference Figure 6 The latch 324 includes a pin seat 327, a hemispherical recess is provided on the top of the pin seat 327, a spherical joint 328 is movably sleeved in the hemispherical recess, a pin head 329 is fixedly connected to the top of the spherical joint 328, and the pin head 329 is inserted into the bottom notch of the connecting block 4.

[0026] Since the main component 2 of the holding rod can be tilted, the bottom slot of the connecting block 4 may be tilted, causing an angle between the axis of the slot at the bottom of the connecting block 4 and the axis of the latch 324, resulting in the latch 324 being unable to smoothly enter the slot. Therefore, through the structural setting of the latch 324 and the connection method between the spherical joint 328 and the pin seat 327, the angle of the pin head 329 can be adjusted to adapt to the tilt condition of the connecting block 4.

[0027] Reference Figure 6 The pin head 329 is arranged in a truncated cone shape, and its top diameter is smaller than the bottom diameter.

[0028] When the connecting block 4 is tilted, even if the angle of the pin head 329 is adjusted, the axis of the pin head 329 may not overlap with the axis of the slot at the bottom of the connecting block 4, resulting in an error between the pin head 329 and the slot. By setting the pin head 329 to a truncated cone shape, the fault tolerance rate when the pin head 329 is inserted into the slot can be improved, so that the pin 324 can be smoothly connected to the connecting block 4.

[0029] Reference Figure 7 A circular groove 10 is provided on the top of several unit steel frames 21 and the top of the rod tail 22, and a circular plug plate 9 is fixedly connected to the bottom of several unit steel frames 21 and the bottom of the rod head 23. The size of the circular plug plate 9 is adapted to the size of the circular groove 10, and several unit steel frames 21, between the rod tail 22 and the unit steel frame 21, and between the unit steel frame 21 and the rod head 23 are connected in combination through several connectors 11.

[0030] When the pole main component 2 is assembled and a new unit steel frame 21 is added to the pole body, the position positioning and pre-fixing effects are achieved by inserting the circular plug plate 9 on one component into the circular groove 10 of another component, thereby improving the convenience of the assembly process.

[0031] Reference Figure 8 The connector 11 includes a top block 111, a plug post 112 is fixedly connected to the bottom of the top block 111, a rotary hole is provided at the bottom of the plug post 112, an inner column 113 is rotatably sleeved in the rotary hole, the top of the inner column 113 is transmission-connected to the top of the rotary hole through a torsion spring 115, a square plate 114 is fixedly connected to the bottom of the inner column 113, a bottom block 116 is provided at the bottom of the top block 111, a square channel 117 is opened at the top of the bottom block 116 and passes through the bottom, the cross-sectional shape of the square channel 117 is adapted to the shape of the square plate 114, and the square channel 117 is twisted.

[0032] When adding a new unit steel frame 21 to lift the pole main component 2, several unit steel frames 21 are combined and connected through the connector 11. The combination process is that the square plate 114 passes through the square channel 117 from the top of the bottom block 116. Since the square channel 117 is in a twisted state, when the square plate 114 passes through, it rotates as the twisting angle of the square channel 117 changes. After the square plate 114 passes through the square channel 117, the square plate 114 rotates and resets under the torsion of the torsion spring 115, thereby making it impossible for the square plate 114 and the bottom opening of the square channel 117 to be separated, thereby achieving an automatic locking effect, so that the unit steel frame 21 can be quickly assembled when added to the pole body, thereby improving work efficiency.

[0033] Reference Figure 8 The sides of the square plate 114 are all inclined inwards.

[0034] The square plate 114 is formed into a table shape. When the square plate 114 passes through the inner cavity of the square channel 117, only the edges of the square plate 114 form linear contact with the inner wall of the square channel 117, thereby avoiding the square plate 114 from getting stuck due to excessive thickness of the side wall. In this way, the thickness of the square plate 114 can ensure its strength.

[0035] Reference Fig. 9 The connector 11 also includes a polygonal rod 118, which passes through the square plate 114 and the inner column 113 from the bottom of the square plate 114 to the inside of the rotary hole of the plug column 112. A positioning recess a matching the shape of the polygonal rod 118 is provided at the top of the rotary hole of the plug column 112. The side wall of the polygonal rod 118 is located at the top of the inner column 113 and is fixedly connected to an anti-slip frame 119.

[0036] Although the structural setting of the connector 11 can achieve a quick assembly effect, there is a risk of accidental disconnection. For example, the torsion spring 115 may cause torque failure or breakage at the connection during long-term use. At this time, the square plate 114 cannot be rotated and reset after passing through the square channel 117. It can be rotated manually, but the lack of torque limit may cause self-spin. In order to improve safety, a polygonal rod 118 is provided. By pushing the polygonal rod 118 to embed it into the positioning recess a, the rotation of the square plate 114 is limited, thereby preventing accidental disconnection.
