Technical Field

The utility model relates to the field of engineering construction, in particular to a kind of lifting equipment for engineering.

Background Art

With the rapid development of industrial society, my country's infrastructure projects have also made great progress, and various high-rise building projects have also increased. Hoisting equipment can transport heavy objects to high places, which can greatly improve the progress of engineering projects. Therefore, it is widely used in daily engineering construction. However, the defect of traditional hoisting equipment is that the hoisted objects are prone to swaying during the hoisting process, which is not stable enough and brings safety hazards. Therefore, it is in urgent need of improvement.

Publication number CN219217290U discloses a construction engineering lifting equipment, which includes a main mechanism, an adjusting and protecting mechanism and a winding and supporting mechanism. The adjusting and protecting mechanism is located above the main mechanism, and the winding and supporting mechanism is located above the adjusting and protecting mechanism. The main mechanism includes a device body and a connecting plate, and the fixing plate is fixedly installed in the middle of the left and right ends of the upper end of the device body.

The construction engineering hoisting equipment, by installing an adjustment protection mechanism, realizes that the device body can be operated to adjust the L-shaped support plate to a position suitable for the hoisting material, and limit the hoisting material to prevent the hoisting material from being shifted due to external factors during the lifting process. The design of the slider and the slide groove provides a limiting effect for the load-bearing plate, so that the load-bearing plate can move upward in a supported manner during the material hoisting process, further improving the stability of the hoisting work of the device body.

The utility model, through the above-mentioned design, alleviates the defect of the traditional hoisting structure that the hoisted object is not stable enough during the hoisting process to a certain extent. However, the existing technology still has room for improvement:

The lifting structure designed by the existing technology still adopts the traditional clamping method to lift heavy objects. However, in daily practical use, long-term operation between mechanical parts will cause wear. At this time, the clamping force of the clamp will decrease and the clamp will become loose. At this time, if the clamp is used to clamp objects of the same weight as before, the loose clamp will cause unstable clamping, causing the heavy object to fall, creating a hidden danger.

DETAILED DESCRIPTION

The utility model is further described in detail below in conjunction with the accompanying drawings.

The working principle of the utility model is shown in Figures 1 to 4: a kind of engineering lifting equipment, including a lifting plate 1, which is designed in a disc shape, with a square lifting port 2 in the middle, and a fixed block 3 is fixedly connected to the middle of each side of the square lifting port 2 around the top of the lifting plate 1. A rotating shaft 4 is inserted on the fixed block 3. The part of the rotating shaft 4 that exceeds the fixed block 3 outward is thinner, and a gear 5 is fixedly connected thereto. At the same time, a base support 6 is fixedly connected to the bottom end of the lifting plate 1, and a rack 7 is connected to the bearing at the top end of the base support 6. The rack 7 is meshed with the gear 5. Therefore, the rotation of the rack 7 can drive the gear 5 to rotate, and then drive the rotating shaft 4 thereon to rotate.

In order to drive the rack 7 to rotate, the utility model has a motor 8 fixedly connected to the front end of the front shaft 4, and the output shaft of the motor 8 is fixedly connected to the front end shaft 4. The motor 8 drives the shaft 4 in that direction and the gear 5 thereon to rotate. Under the influence of the toothed connection, the rack 7 is driven to rotate, thereby driving the gears 5 in other directions to rotate.

The end of the rotating shaft 4 facing the lifting port 2 is fixedly connected with a connecting piece 9. The reason for driving the rotating shaft 4 to rotate is to drive the connecting piece 9 to make an arc motion around the rotating shaft 4. At the same time, an insertion shaft 10 is inserted at the bottom end of the connecting piece 9. The insertion shaft 10 is rotatably connected to a connecting piece 2 11 at one end facing the lifting port 2. A carrying frame 12 is arranged inside the lifting port 2. The front and rear ends of the carrying frame 12 and the middle parts of both sides are fixedly connected with an insertion shaft 2 13. The insertion shaft 2 13 is rotatably connected to the bottom end of the connecting piece 2 11. Therefore, when the rotating shaft 4 rotates, the connecting piece 9 fixedly connected thereto will make an arc motion with the rotating shaft 4 as the center and the length of the connecting piece 9 itself as the radius. At the same time, the insertion shaft 10 at the other end and the various components thereunder are driven to rise and fall. Since the carrying frame 12 receives forces from four directions of front, back, left, right, etc., it can achieve force balance, so that it will not deviate during the lifting process, thereby achieving the effect of driving the carrying frame 12 to move up and down.

Of course, in order to enhance the stability of the supporting frame 12 during the lifting process, an additional vertical limiting structure can be installed on the bottom end of the supporting frame 12 or the plug-in shaft 13 to limit its movement in the vertical direction. Since the above-mentioned additional limiting structure belongs to the existing technology, its technical principle will not be repeated here.

Finally, the heavy objects to be hoisted need to be moved and transferred, so the utility model is provided with a mobile structure 14 under the bottom bracket 6 to meet the above requirements, and receiving parts 15 are provided at both ends of the mobile structure 14 to cooperate with it. The front and rear ends of the bottom of the receiving part 15 are fixedly connected to the supporting feet 22, and the bottom of the supporting feet 22 is fixedly connected to the supporting sheet 23.

The above components together constitute the general appearance structure of the engineering lifting equipment of the utility model.

In order to further explain the detailed working principle of the engineering hoisting equipment of the utility model, the above-mentioned moving structure 14 includes a moving block 16 fixedly connected to the front and rear ends of the bottom bracket 6, and the front and rear ends of the upper parts of both sides of the moving block 16 are plugged with a horizontally arranged sliding rod 17, and the two sides of the sliding rod 17 are fixedly connected to the receiving member 15, and the moving block 16 and the motor 8 are connected to each other through a support frame 24. The middle part of the bottom end of both sides of the moving block 16 is threadedly connected with a screw rod 18, and both sides of the screw rod 18 are rotatably connected to the receiving member 15. A slide groove 19 is opened in the middle part of the bottom end of the moving block 16, and a slide rail 20 is slidably connected in the slide groove 19, and both sides of the slide rail 20 are fixedly connected to the receiving member 15. The front and rear ends of one of the receiving members 15 on both sides away from the screw rod 18 are fixedly connected with a motor box 21, and the motor box 21 is provided with a driving motor used in conjunction with the screw rod 18.

The technical effect achieved by the technical solution composed of the above-mentioned technical features is: the driving motor inside the driving motor box 21 works, which can drive the screw rod 18 to rotate. Under the influence of the threaded connection, the moving block 16 thereon begins to move under force, and the design of the slide rail 20 and the slide rod 17 can ensure its stability.

It should be specially noted here that the components described and identified in the text and drawings of the utility model are the key components constituting the utility model, and the remaining non-key components or obvious prior art components include but are not limited to: screws, nuts, rotating parts and related supporting structures, as well as technical features similar to the prior art, etc. are not shown. However, this does not mean that the above-mentioned components do not exist in the utility model, nor can it be interpreted as a practical limitation on the utility model.

It should be additionally explained here that the driving of each component in the utility model and the effects achieved therefrom, including but not limited to the driving of the motor 8 and the driving of the driving motor provided inside the motor box 21, etc., all require additional wiring or the installation of components such as a power supply to be realized, and if one wants to obtain data such as the rotation speed, it is necessary to additionally install a control module or a single-chip microcomputer and program it to achieve this. Since the above-mentioned wiring, power supply, control module, single-chip microcomputer and other components are all mature technologies currently available on the market and are also technologies well known to ordinary technicians in this field, they are not explained or identified in the text and drawings of the utility model, and their technical principles will not be repeated here.

The specific implementation of the present invention has been described in detail above, so it will not be repeated here.

The utility model and its implementation methods are described above, and such description is not restrictive. The drawings are only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
