Description

Technical Field

[0001] The utility model relates to the technical field of hoists, in particular to an auxiliary hoist for electromechanical engineering installation. Background Art

[0002] When installing electromechanical engineering equipment, due to the large size and weight of the electromechanical engineering equipment, suitable auxiliary hoists are generally used to provide auxiliary functions for the installation of the electromechanical engineering equipment, thereby reducing the labor burden of personnel.

[0003] The existing patent CN218453919U provides an auxiliary hoist for electromechanical engineering installation, which brings the following beneficial effects: "After the auxiliary hoist is moved to a suitable position by the universal wheel, the first motor is operated to drive the worm on the left to rotate by controlling the switch group. At this time, due to the transmission effect of the belt, the two worms will rotate together. Affected by the meshing connection relationship between the turbine and the worm, the rotating rod can be rotated, so that the universal wheel swings in the horizontal direction. Finally, the hollow seat will replace the universal wheel and make direct contact with the ground, thereby realizing the position limitation of the auxiliary hoist and ensuring the stability of subsequent lifting work." However, since the adjustment process is adjusted from a vertical direction to a horizontal direction by the universal wheel, the universal wheel may slip during operation, resulting in the inability of the hollow seat to fall according to the pre-set fixed point position, resulting in a fixed point failure and a deviation in the fall. If a straight up and down retractable universal wheel can be provided, the problem can be well solved. In view of this, an auxiliary hoist for electromechanical engineering installation is proposed.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 The utility model provides a new technical solution: an auxiliary lifting device structure for electromechanical engineering installation, comprising a transfer base 1, a lifting device 2 is arranged on the upper surface of the transfer base 1, and grooves 3 are provided on both sides of the transfer base 1;

[0025] An adjustment mechanism is arranged in the transfer base 1, and is used to adjust the distance between the transfer base and the ground to form a support. The adjustment mechanism includes four second slide grooves 9, and the four second slide grooves are arranged on the lower surface of the bottom plate of the transfer base 1;

[0026] The supporting mechanism is arranged on the transfer base 1 and is used for supporting and preventing the sling from rolling over when the sling is in operation. The supporting mechanism includes two first slide grooves 4 which are arranged on opposite surfaces of the inner wall of the groove 3 .

[0027] Furthermore, the adjustment mechanism also includes four hydraulic machines 10, four hydraulic rods 11 and four sliders 12. The four hydraulic machines 10 are fixedly mounted on the lower surface of the top plate of the transfer base 1, the four hydraulic rods 11 are slidably mounted on the inner surfaces of the four hydraulic machines 10, the four sliders 12 are fixedly mounted on one end of the four hydraulic rods 11 away from the hydraulic machines 10, and the lower surfaces of the four sliders 12 are all inclined.

[0028] Furthermore, the adjustment mechanism also includes four slide rails 13 , which are all fixedly mounted on the lower surface of the top plate of the transfer base 1 , and the four slide rails 13 are all slidably connected to the slider 12 .

[0029] Furthermore, the adjustment mechanism also includes four fixed blocks 14, four fixed plates 15, eight springs 16 and four universal wheels 17. The four fixed blocks 14 are all arranged on the lower surface of the four sliders 12, and the upper surfaces of the four fixed blocks 14 are all arranged in an inclined surface. The four fixed plates 15 are respectively fixedly installed on the lower surfaces of the four fixed blocks 14, the eight springs 16 are respectively fixedly installed on the lower surfaces of the four fixed plates 15, and the lower ends of the eight springs 16 are all fixedly installed on the upper surface of the bottom plate of the transfer base 1, and the four universal wheels 17 are respectively arranged on the lower surfaces of the four fixed plates 15.

[0030] Furthermore, the supporting mechanism also includes two electric push rods 5 and two fixed sticks 6. The two electric push rods 5 are respectively fixedly installed in the inner walls of the two grooves 3, and the two fixed sticks 6 are respectively fixedly installed on the upper surfaces of the two electric push rods 5, and the two fixed sticks 6 are both slidably connected to the first slide groove 4.

[0031] Further, when the electromechanical engineering installation auxiliary hoist is used, by starting the hydraulic press 10, the hydraulic press 10 pushes the hydraulic rod 11 which is slidably mounted on the inner surface to move through operation, and at the same time, the hydraulic rod 11 applies a thrust to the slider 12 fixedly mounted on the left end to make it slide in the slide rail 13. At this time, the inclined surface of the slider 12 hits the inclined surface of the fixed block 14 arranged on the lower surface, and applies a downward thrust to the fixed block 14 to make it move downward. At the same time, the fixed block 14 applies a downward pressure to the fixed plate 15 fixedly mounted on the lower surface to make it move downward. At the same time, the fixed plate 15 applies pressure to the spring 16 fixedly mounted on the lower surface to make it contract. At the same time, the fixed plate 15 applies a downward thrust to the universal wheel 17 fixedly mounted on the lower surface to make it move downward and protrude the transfer base 1. At this time, the spreader can be moved. After the movement, by starting the hydraulic press 10, the hydraulic press 10 applies a rightward pulling force to the hydraulic rod 11 which is slidably mounted on the inner surface through operation. At this time, the hydraulic rod 1 1 drives the slider 12 fixed at the left end to move right to complete the adjustment. At this time, the slider 12 no longer applies pressure to the fixed block 14 set on the lower surface, and the spring 16 is no longer under force. At this time, the spring 16 expands and applies an upward thrust to the fixed plate 15 fixedly installed at the upper end, so that it moves upward. At the same time, the fixed plate 15 drives the universal wheel 17 fixedly installed on the lower surface to retract into the transfer base 1. At this time, the transfer base 1 contacts the ground to form a support. At this time, the electric push rod 5 can be started. The electric push rod 5 applies an upward thrust to the fixed stick 6 fixedly installed at the upper end through operation to make it move upward. At the same time, the fixed stick 6 drives the support plate 7 rotatably mounted on the outer surface to move upward. The support plate 7 gradually becomes horizontal while moving upward. At the same time, the support plate 7 applies an outward thrust to the telescopic rod 8 rotatably mounted on the inner surface, so that it moves outward and gradually becomes inclined. At this time, the telescopic rod 8 supports the transfer base 1 to prevent it from tipping over, which is more convenient.

[0032] Working principle: When the electromechanical engineering installation auxiliary hoist is used, the hydraulic press 10 is started, and the hydraulic press 10 pushes the hydraulic rod 11 set on the inner surface sliding sleeve to move through operation. At the same time, the hydraulic rod 11 applies a thrust to the slider 12 fixedly installed on the left end to make it slide in the slide rail 13. At this time, the inclined surface of the slider 12 hits the inclined surface of the fixed block 14 set on the lower surface, and applies a downward thrust to the fixed block 14 to make it move downward. At the same time, the fixed block 14 applies downward pressure to the fixed plate 15 fixedly installed on the lower surface to make it move downward. At the same time, the fixed plate 15 applies pressure to the spring 16 fixedly installed on the lower surface to make it contract. At the same time, the fixed plate 15 applies a downward thrust to the universal wheel 17 fixedly installed on the lower surface to make it move downward and protrude the transfer base 1. At this time, the spreader can be moved. After moving, the hydraulic press 10 is started, and the hydraulic press 10 applies a rightward pulling force to the hydraulic rod 11 set on the inner surface sliding sleeve through operation. At this time, the hydraulic rod 11 drives the slider 12 fixedly installed at the left end to move right to complete the adjustment. At this time, the slider 12 no longer applies pressure to the fixed block 14 set on the lower surface, and the spring 16 is no longer under force. At this time, the spring 16 expands and applies an upward thrust to the fixed plate 15 fixedly installed at the upper end, so that it moves upward. At the same time, the fixed plate 15 drives the universal wheel 17 fixedly installed on the lower surface to retract into the transfer base 1. At this time, the transfer base 1 contacts the ground to form a support. At this time, the electric push rod 5 can be started. The electric push rod 5 applies an upward thrust to the fixed stick 6 fixedly installed at the upper end through operation to make it move upward. At the same time, the fixed stick 6 drives the support plate 7 rotatably mounted on the outer surface to move upward. The support plate 7 gradually becomes horizontal while moving upward. At the same time, the support plate 7 applies an outward thrust to the telescopic rod 8 rotatably mounted on the inner surface, so that it moves outward and gradually becomes inclined. At this time, the transfer base 1 is supported by the telescopic rod 8.
