Description

Technical Field

[0001] The present application relates to the technical field of lifting and loading equipment, and in particular to a lifting mechanism for lifting and loading mechanical equipment. Background Art

[0002] Small gantries are often used in the process of lifting and loading and unloading mechanical equipment, especially in low-rise factories, which are not suitable for installing large tower cranes. However, existing small lifting frames can only move mechanical equipment up and down. When the mechanical equipment is to be moved longitudinally, due to the wide width of the gantry, multiple people are required to push the gantry together to achieve the longitudinal movement of the mechanical equipment. However, such operation wastes too much manpower and brings a bad user experience to users. Utility Model Content

[0019] Example

[0020] See also Figure 1 - Figure 4 The present application provides a technical solution: a lifting mechanism for a lifting and loading and unloading mechanical equipment, comprising a base 110, a first load-bearing wheel 120, a support plate 130, a screw rod 140, a motor 150, a gear transmission member 160, a guide rod 180, a connecting block 190, a column 191, a bracket 192, a second load-bearing wheel 193, an I-beam 194 and an electric hoist 195, wherein the first load-bearing wheel 120 is fixed to the lower surface of the base 110, and the first load-bearing wheel 120 is provided with a plurality of first load-bearing wheels 120. The first bearing wheels 120 are equidistantly arranged on the base 110, and the base 110 is more evenly stressed. The support plate 130 is fixed on the upper surface of the base 110. The end of the screw rod 140 is rotatably arranged in the base 110. A rotating member 170 is fixedly installed in the base 110. The end of the screw rod 140 is rotatably arranged in the rotating member 170. The arrangement of the rotating member 170 makes the screw rod 140 rotate more smoothly. The rotating member 170 in this embodiment is a bearing, and the guide rod 180 is fixed in the base 110.

[0021] The output shaft of the motor 150 and the screw rod 140 are connected together through the gear transmission member 160. The gear transmission member 160 is composed of two bevel gears. The two bevel gears are meshed with each other. The two bevel gears are fixedly mounted on the output shaft of the motor 150 and the screw rod 140 respectively. The connecting block 190 is threadedly sleeved on the screw rod 140. The connecting block 190 is also slidably sleeved on the guide rod 180. The lower end of the column 191 is fixed on the upper surface of the connecting block 190, and the upper end of the column 191 is fixed on the lower surface of the I-beam 194. On the surface, the electric hoist 195 is arranged on the I-beam 194, one end of the bracket 192 is fixed on the outer wall of the column 191, and the second load-bearing wheel 193 is installed on the other end of the bracket 192. The second load-bearing wheel 193 is slidably arranged in the base 110, and also includes a reinforcing rib 196, one end of the reinforcing rib 196 is fixed on the lower surface of the I-beam 194, and the other end of the reinforcing rib 196 is fixed on the outer wall of the column 191. The setting of the reinforcing rib 196 makes the column 191 and the I-beam 194 more firmly fixed together.

[0022] Specifically, the working principle of the lifting mechanism for lifting and loading and unloading mechanical equipment is as follows: when in use, the I-beam 194 and the electric hoist 195 can realize the up and down and lateral movement of the mechanical equipment. When the mechanical equipment needs to be moved longitudinally, the motor 150 works, and the rotation of the output shaft of the motor 150 drives the gear transmission member 160 to rotate, and the rotation of the gear transmission member 160 drives the screw rod 140 to rotate. The connecting block 190 realizes longitudinal movement under the joint action of the screw rod 140 and the guide rod 180, that is, the longitudinal movement of the mechanical equipment is realized. The arrangement of multiple first load-bearing wheels 120, brackets 192 and second load-bearing wheels 193 makes the column 191 move more smoothly, even if the base 110 is subjected to more uniform force, the column 191 is prevented from tipping over, thereby improving the safety of the equipment. The lifting mechanism for lifting and loading and unloading mechanical equipment can realize the up and down, lateral and longitudinal movement of the mechanical equipment, that is, there is no need for multiple people to push the gantry crane, which saves manpower and brings a better user experience.

[0023] It should be noted that the specific model specifications of the motor 150 and the electric hoist 195 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0024] The power supply and principle of the motor 150 and the electric hoist 195 are clear to those skilled in the art and will not be described in detail here.
