Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and more specifically, to a lifting device for engineering services. Background Technology

[0002] Lifting equipment for engineering services refers to mechanical equipment used for lifting and moving heavy objects during engineering construction, maintenance, and repair processes.

[0003] There are many existing technologies for lifting equipment, such as:

[0004] Chinese Patent Application No. 202121576868.8 discloses a lifting device body with a feeding mechanism movably connected inside. The feeding mechanism includes a support plate, and a movable plate is movably connected to the upper surface of the support plate. A clamping mechanism is provided on the upper surface of the movable plate, and the clamping mechanism includes a clamping plate. The clamping plate is rotatably connected to the upper surface of the movable plate by a torsion spring. The equipment is placed on the feeding mechanism provided on the lifting device body, and the equipment is fixed by the clamping mechanism, which can increase the stability of the equipment and prevent the equipment from shaking during movement. After the equipment is lifted, the feeding mechanism can drive the equipment to move towards the building platform, thereby shortening the distance between the lifting device and the building platform, making it easier for workers to remove the equipment and reducing the workload of workers.

[0005] However, existing lifting equipment for engineering services suffers from uneven ground and relatively poor stability during lifting, especially at higher lifting heights. When the lifting device's feeding mechanism carries the heavy load towards the building platform, it may sway or deviate, causing inconvenience and safety hazards to operation. In view of this, we propose a lifting device for engineering services. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a lifting device for engineering services;

[0007] To achieve the above objectives, this utility model provides a lifting device for engineering services, including a mounting plate. A T-shaped groove is provided at the bottom of the mounting plate, and a T-shaped slider is slidably connected to the inner wall of the T-shaped groove. A movable block is fixedly connected to the bottom of the T-shaped slider. A support plate is fixedly connected to the bottom of the mounting plate, and a threaded rod is rotatably connected inside the support plate. The outer surface of the threaded rod is threadedly connected to the inside of the movable block, and a counterweight is fixedly connected to the bottom of the movable block.

[0008] The counterweight moves along the length of the threaded rod on the moving block, changing the center of gravity of the lifting equipment.

[0009] As a further improvement to this technical solution, a motor is fixedly connected to the front of the support plate, and the end of the motor output shaft extends into the support plate and is fixedly connected to the end of the threaded rod.

[0010] As a further improvement to this technical solution, side plates are fixedly connected to the left and right surfaces of the mounting plate. A rectangular groove is provided at the bottom of the side plate. A cylindrical tube end is rotatably connected to the top of the inner surface of the rectangular groove. A worm gear is rotatably connected to the other end of the cylindrical tube. A lead screw is threadedly connected to the shaft of the worm gear. A universal wheel is rotatably connected to the bottom of the lead screw.

[0011] As a further improvement to this technical solution, an elongated groove is provided inside the side plate near the middle end, and a rectangular block is slidably connected to the inner wall of the elongated groove. The rectangular block is rotatably connected to the top of the lead screw.

[0012] As a further improvement to this technical solution, a worm gear is rotatably connected inside the side plate, the outer surface of the worm gear is meshed with the outer surface of the worm wheel, and a rotating handle is fixedly connected to the end of the worm gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] First, the motor rotates, driving the threaded rod to rotate. Then, the rotation of the threaded rod drives the moving block to move back and forth. Next, the movement of the moving block drives the counterweight to move back and forth. The movement of the counterweight changes the position of the center of gravity, making the lifting equipment more stable during use. This prevents the lifting equipment from tilting or deviating during operation, which could cause the equipment and goods to tip over and collide with objects or workers, resulting in damage to the equipment and goods or even injury to personnel, thus increasing safety during use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Lifting equipment for engineering services refers to mechanical equipment used for lifting and moving heavy objects during engineering construction, maintenance, and repair processes.

[0025] Please see Figures 1-4 As shown, this embodiment provides a lifting device for engineering services, including a mounting plate 1. To prevent the lifting device from tilting, the following is specifically provided: a T-shaped groove 12 is provided at the bottom of the mounting plate 1, a T-shaped slider 23 is slidably connected to the inner wall of the T-shaped groove 12, a moving block 21 is fixedly connected to the bottom of the T-shaped slider 23, a support plate 24 is fixedly connected to the bottom of the mounting plate 1, a threaded rod 22 is rotatably connected inside the support plate 24, the outer surface of the threaded rod 22 is threadedly connected to the inside of the moving block 21, a counterweight 2 is fixedly connected to the bottom of the moving block 21, and the counterweight 2 moves along the length of the threaded rod 22 on the moving block 21 to change the center of gravity of the lifting device. However, in the use of existing lifting devices for engineering services, uneven ground and relatively poor stability of some lifting devices during the lifting process, especially when the lifting height is high, the feeding mechanism on the lifting device body may shake or deviate when carrying heavy objects towards the building platform, causing inconvenience and safety hazards to the operation.

[0026] The improvement in this embodiment is as follows:

[0027] First, the motor 25 rotates, driving the threaded rod 22 to rotate. Then, the rotation of the threaded rod 22 drives the moving block 21 to move back and forth. Next, the movement of the moving block 21 drives the counterweight 2 to move back and forth. The movement of the counterweight 2 changes the position of the center of gravity, making the lifting equipment more stable during use. This prevents the lifting equipment from tilting or deviating during operation, which could cause the equipment and goods to tip over and collide with objects or workers, resulting in damage to the equipment and goods or even injury to personnel, thus increasing safety during use.

[0028] To facilitate the rotation of the threaded rod 22, a motor 25 is fixedly connected to the front of the support plate 24. The output shaft end of the motor 25 extends into the support plate 24 and is fixedly connected to the end of the threaded rod 22. First, the motor 25 rotates to drive the threaded rod 22 to rotate, thus achieving convenient rotation of the threaded rod 22.

[0029] To prevent the lifting equipment from tilting due to uneven ground, side plates 11 are fixedly connected to the left and right surfaces of the mounting plate 1. A rectangular groove 111 is provided at the bottom of the side plate 11. The top of the inner surface of the rectangular groove 111 is rotatably connected to the end of a cylindrical tube 34. The other end of the cylindrical tube 34 is rotatably connected to a worm gear 32. A lead screw 31 is threadedly connected to the shaft of the worm gear 32. A universal wheel 3 is rotatably connected to the bottom of the lead screw 31. First, the lead screw 31 moves up and down, driving the universal wheel 3 to move up and down. Then, the universal wheel 3 moves up and down to make the equipment stable, so that the lifting equipment will not tilt due to uneven ground.

[0030] Secondly, in order to prevent the lead screw 31 from falling off the worm gear 32, an elongated groove 112 is provided inside the side plate 11 near the middle. A rectangular block 35 is slidably connected to the inner wall of the elongated groove 112. The rectangular block 35 is rotatably connected to the top of the lead screw 31. First, the rectangular block 35 blocks inside the elongated groove 112, and then the rectangular block 35 fixes the end of the lead screw 31, so that the lead screw 31 will not fall off the worm gear 32.

[0031] Considering that the worm gear 32 is inconvenient to rotate, a worm 33 is rotatably connected inside the side plate 11. The outer surface of the worm 33 is meshed with the outer surface of the worm gear 32. A rotating handle 36 is fixedly connected to the end of the worm 33. First, rotating the handle 36 drives the worm 33 to rotate. Then, rotating the worm 33 drives the worm gear 32 to rotate, thus making the rotation of the worm gear 32 convenient.

[0032] In summary, the working principle of this solution is as follows:

[0033] When the ground is uneven, manually turn the handle 36 above the caster 3 at the lower point of the lifting equipment. Turning the handle 36 rotates the worm gear 33, which in turn rotates the worm wheel 32. The worm wheel 32 then moves the lead screw 31 downwards, which in turn moves the caster 3 downwards, thus stabilizing the equipment and preventing it from tilting. The elongated groove 112 blocks the rectangular block 35, which in turn fixes the lead screw 31, preventing it from detaching from the worm wheel 32. The lead screw 31 slides between the rectangular groove 111 and the elongated groove 112 on the side plate 1. 1. When the feeding mechanism on the lifting equipment moves horizontally, carrying the heavy object towards the construction platform, the lifting equipment is prone to tipping over, which can easily damage the equipment and goods, and may also injure workers, posing a safety threat. According to the direction of movement of the lifting equipment, the motor 25 is connected to the power supply. The rotation of the motor 25 drives the threaded rod 22 to rotate. The rotation of the threaded rod 22 drives the moving block 21 to move in the opposite direction to the heavy object. The opposite movement of the moving block 21 drives the counterweight block 2 to move in the opposite direction to the heavy object. The opposite movement of the counterweight block 2 changes the center of gravity position, keeping the lifting equipment stable, reducing the risk of equipment tilting and damage, reducing safety hazards, and increasing safety.
