[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0022] like Figure 1-4 As shown, the utility model proposes an adjustable shoulder pole beam device for lifting, including a beam body 1 and a hook 3. A lifting plate is fixedly provided on the top of the beam body 1. The lifting plate includes a main lifting plate 22 and two auxiliary lifting plates 21. The auxiliary lifting plates 21 are installed on the left and right sides of the beam body 1, and the main lifting plate 22 is installed in the middle of the beam body 1. The main lifting plate 22 and the two auxiliary lifting plates 21 are symmetrically arranged with equal spacing, which can ensure the lifting balance of the shoulder pole beam. Lifting holes 20 are provided on the three lifting plates. When used for lifting, the lifting equipment connects the main lifting plate 22 and the lifting holes 20 on the two auxiliary lifting plates 21 through a lifting rope, thereby ensuring a stable connection between the lifting equipment and the shoulder pole beam.

[0023] Among them, the beam body 1 is provided with a first slide groove 13 and a second slide groove 12 in the upper and lower directions of its length, the first slide groove 13 is connected to the top of the second slide groove 12, and the horizontal width of the first slide groove 13 is greater than the second slide groove 12. The top of the first slide groove 13 is connected to the first strip hole 14 opened at the top of the beam body 1, and the bottom of the second slide groove 12 is connected to the second strip hole 11 opened at the bottom of the beam body 1. Two first sliders 5 are provided in the second slide groove 12 for sliding left and right, and a connecting block 4 is fixed at the bottom of the first slider 5, and the hook 3 is installed at the lower end of the connecting block 4 that penetrates and extends out of the second strip hole 11. In this embodiment, a plurality of slots 121 are provided at equal intervals at the bottom of the second slide groove 12 along the left and right length directions, and a locking tooth 52 that matches the slot 121 is provided at the bottom of the first slider 5. In addition, when the present application is actually used, a tooth plate structure that matches the slot 121 can also be installed horizontally along the bottom of the second slide groove 12 to replace the above-mentioned slot 121.

[0024] By cooperating the latching teeth 52 below the first slider 5 with the latching groove 121 at the bottom of the second slide groove 12, the position of the first slider 5 in the second slide groove 12 can be effectively adjusted, and then the distance between the two hooks 3 can be effectively adjusted, so that the device can be adapted to the use of lifting operations under different working conditions.

[0025] A connecting rod 51 is vertically fixedly connected to the upper end of the first sliding groove 5, and a roller assembly is slidably arranged in the first sliding groove 13. The connecting rod 51 is vertically movably arranged in the roller assembly. An abutment block 511 is fixedly arranged on the connecting rod 51, and a spring 512 is sleeved on the connecting rod 51. The two ends of the spring 512 abut against the abutment block 511 and the roller assembly respectively. Specifically, the roller assembly includes a support 61 and two supporting rollers 62. The two supporting rollers 62 are supported at the bottom of the first sliding groove 13 and are horizontally installed on the support 61. A second through hole is vertically penetrated in the middle of the support 61, and the connecting rod 51 is vertically movably arranged in the second through hole.

[0026] Since the hook 3 itself has a certain weight, in order to reduce the friction when adjusting its position, the present application utilizes the elastic force of the spring 512, and can lift the connecting rod 51 upward to a certain height through the abutment block 511, thereby making the first slider 5 move upward in the second slide groove 12 and disengage the latching tooth 52 below it from the latching groove 121, and then utilizing the horizontal rolling of the supporting roller 62 of the roller assembly in the first slide groove 13 to drive the left and right horizontal adjustment of the first slider 5, the hook 3 and other structures. By supporting the rolling of the supporting roller 62 in the first slide groove 13, the friction resistance between the roller assembly, the first slider 5 and other structures and the bottom surface of the corresponding slide groove when the hook 3 is adjusted to the left and right can be significantly reduced, making the adjustment of the hook 3 more labor-saving and convenient.

[0027] The second slider 7 is slidably mounted in the first strip hole 14, and the second slider 7 is an I-shaped structure. The second slider 7 vertically penetrates the first through hole 70, and the upper end of the connecting rod 51 is slidably mounted in the first through hole 70. The top opening of the first through hole 70 is threadedly connected with a bolt 8, and the bolt 8 is in contact with the connecting rod 51. Regardless of whether the first slider 5 rises or falls, the upper end of the connecting rod 51 is always slidably mounted in the first through hole 70 and will not break out of the first through hole 70.

[0028] When the position of the hook 3 below is adjusted, by screwing the bolt 8, the lower end of the bolt 8 moves downward against the upper end of the connecting rod 51 and squeezes the spring 512, thereby pressing the first slider 5 to move downward and causing the latching tooth 52 to engage with the corresponding latching groove 121, thereby locking the position of the hook 3, making the adjustment of the hook 3 of the device very convenient and quick.

[0029] When using the utility model to adjust the hook 3, first screw the corresponding bolts 8 above the two hooks 3 upwards, and under the elastic force of the spring 512, the abutment block 511, the connecting rod 51, the first slider 5 and other structures will move upwards, and the latching teeth 52 will be disengaged from the slot 121. When the hook 3 is adjusted left and right, the roller 62 is supported to roll in the first slide slot 13, which can significantly reduce the friction resistance between the first slider 5 and other structures and the inside of the beam body 1, making the adjustment of the hook 3 more labor-saving and convenient. After the hook 3 is adjusted to the right position, screw the bolt 8 downwards to make it move downward against the connecting rod 51, the first slider 5 and other structures, and make the latching teeth 52 engage with the corresponding slot 121, so that the position of the hook 3 can be locked, making the adjustment of the hook 3 of the device very convenient and quick.
