Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a lifting device for building engineering with high stability. Background Technology

[0002] Building construction refers to engineering entities or building products that create functional spaces and various facilities for human life, production, protection and other activities. It covers the entire process from project planning, design, construction to final acceptance, and involves multiple disciplines and fields. During the construction process, some materials need to be transported to high-rise buildings, which requires the use of lifting devices for lifting and transportation.

[0003] There are still some problems with existing lifting devices for construction projects. Current lifting devices use a hoist to drive the lifting frame to rise and fall to transport materials. Due to the high load, the center of gravity is too high, and the device is prone to instability when the material is unbalanced or when there is external disturbance. Therefore, those skilled in the art provide a lifting device for construction projects with high stability to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly stable lifting device for construction projects. By setting a highly stable base at the bottom of the support, the center of gravity of the equipment is lowered during use, improving stability. At the same time, the auxiliary structure provides auxiliary guidance, reducing the swaying of the lifting frame and improving the stability of use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-stability lifting device for construction engineering, comprising a support frame, a lifting frame provided at the center of the lower inner wall of the support frame, auxiliary structures provided on the front and rear end faces of the two side supports of the lifting frame, and a highly stable base provided on the lower end face of the lower support of the lifting frame. The high-stability base includes a base frame, a frame fixedly connected to the upper end of the base frame, a fixed connection between the frame and the support, a placement plate fixedly connected to the upper rear end of the base frame, a plurality of counterweights provided on the upper end of the placement plate, a plurality of ball bearings arranged laterally and rollingly connected at the front center of the upper end of the base frame, the lower ends of the plurality of counterweights respectively abutting the upper ends of the plurality of ball bearings, and a handle fixedly connected to the center of the front end of each of the plurality of counterweights; A buffer structure is provided on the upper end face of the lower end frame of the lifting frame; By inserting one end of multiple counterweights between the base frame and the frame, and by setting multiple balls, the multiple counterweights roll on the multiple balls, which makes it easy to move the balls between the base frame and the frame. This increases the overall weight of the high-stability base, lowers the center of gravity, and thus increases the stability of the equipment.

[0006] Furthermore, a rear baffle is fixedly connected to the center of the upper end face of the base frame near the rear. The above technical solution prevents multiple counterweights from falling off the rear of the base frame.

[0007] Furthermore, the buffer structure includes a base plate, which is fixedly connected to the inside of the frame. Multiple air shock absorbers are fixedly connected to the upper surface of the base plate in a rectangular arrangement. Rubber pads are fixedly connected to the upper surfaces of the front and rear end frames of the base plate. With the above technical solution, the lifting frame descends slowly, and the bottom of the lifting frame first contacts multiple air shock absorbers and rubber pads, reducing the impact force when the lifting frame descends, thereby increasing the service life of the lifting frame.

[0008] Furthermore, taking one of the auxiliary structures as an example, the auxiliary structure includes two connecting plates, which are respectively disposed at the upper and lower ends of the front end face of the support on one side of the lifting frame. A guide rod is fixedly connected between the two connecting plates, and a sleeve plate is slidably sleeved on the outside of the guide rod. The sleeve plate is fixedly connected to one side wall of the lifting frame. Through the above technical solution, during the movement of the lifting frame, the four sleeve plates slide upward, reducing the swaying caused by external factors and load shift.

[0009] Furthermore, a graphene layer is fixedly sleeved on the outer wall of the guide rod; The above technical solution reduces friction between the sleeve and the guide rod, thus improving the service life of the equipment.

[0010] Furthermore, a hoist is fixedly connected to one side of the lower inner wall of the support, and a hoisting steel wire is wound around the winding end of the hoist. A first guide wheel is fixedly connected to the inside of the upper support of the hoist, and a second guide wheel is fixedly connected to one side of the center of the upper inner wall of the support. The outer side of the hoisting steel wire is attached to the outer side wall of the first guide wheel and the second guide wheel, extending to the lower part of the inner center of the support, and a connecting buckle is fixedly connected to the end of the wire. The connecting buckle is fixedly connected to the hoisting frame. The above technical solution controls the start of the hoist, which then winds up the hoisting steel wire. After being guided by the first and second guide wheels, the pulling force is directed upwards, thereby pulling the hoisting frame upwards.

[0011] This utility model has the following beneficial effects: In this invention, by inserting one end of multiple counterweights between the base frame and the frame, and by setting multiple balls, the multiple counterweights roll on the multiple balls, which facilitates the movement of the balls between the base frame and the frame. This increases the overall weight of the high-stability base, lowers the center of gravity, and thus increases the stability of the equipment. The auxiliary structure provides auxiliary guidance, reduces the swaying of the lifting frame, and improves the stability of use.

[0012] In this invention, the lifting frame descends slowly, and the bottom of the lifting frame first contacts multiple air shock absorbers and rubber pads to reduce the impact force when the lifting frame descends, thereby increasing the service life of the lifting frame.

[0015] 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.

[0016] Reference Figure 1-4An embodiment of this utility model provides a high-stability lifting device for construction engineering, including a support 1, a lifting frame 3 at the center of the lower inner wall of the support 1, auxiliary structures 10 on the front and rear end faces of the support 1 on both sides of the lifting frame 3, and a high-stability base 2 on the lower end face of the support 1 at the lower end of the lifting frame 3.

[0017] like Figure 1 , 2 As shown in Figures 3 and 4, the high-stability base 2 includes a base frame 201. A frame 202 is fixedly connected to the upper surface of the base frame 201. The frame 202 is fixedly connected to the support 1. A placement plate 203 is fixedly connected to the upper rear end of the base frame 201. Multiple counterweights 204 are provided on the upper surface of the placement plate 203. Multiple balls 206 are horizontally arranged and rolled near the center of the upper surface of the base frame 201. The lower ends of the multiple counterweights 204 are respectively attached to the upper ends of the multiple balls 206. A handle 205 is fixedly connected to the center of the front surface of each of the multiple counterweights 204. By inserting one end of the multiple counterweights 204 between the base frame 201 and the frame 202, and through the arrangement of the multiple balls 206, the multiple counterweights 204 roll on the multiple balls 206, making it easy to move the balls 206 between the base frame 201 and the frame 202. This increases the overall weight of the high-stability base 2, lowers the center of gravity, and thus increases the stability of the equipment.

[0018] A buffer structure 9 is provided on the upper end face of the lower frame 202 of the lifting frame 3 to reduce the impact force when the lifting frame 3 descends.

[0019] A rear baffle 207 is fixedly connected to the center of the upper end face of the base frame 201 to prevent multiple counterweights 204 from falling off the rear end of the base frame 201.

[0020] like Figure 2 , 3 As shown in Figure 4, the buffer structure 9 includes a base plate 901, which is fixedly connected to the inside of the frame 202. Multiple air shock absorbers 902 are fixedly connected in a rectangular arrangement on the upper surface of the base plate 901. Rubber pads 903 are fixedly connected to the upper surfaces of the frame 202 at both ends of the base plate 901. When the lifting frame 3 descends slowly, the bottom of the lifting frame 3 first contacts the multiple air shock absorbers 902 and the rubber pads 903, reducing the impact force when the lifting frame 3 descends, thereby increasing the service life of the lifting frame 3.

[0021] Taking one of the auxiliary structures 10 as an example, the auxiliary structure 10 includes two connecting plates 1001. The two connecting plates 1001 are respectively set at the upper and lower ends of the front end face of the support 1 on one side of the lifting frame 3. A guide rod 1002 is fixedly connected between the two connecting plates 1001. A sleeve plate 1003 is slidably sleeved on the outside of the guide rod 1002. The sleeve plate 1003 is fixedly connected to one side wall of the lifting frame 3. During the movement of the lifting frame 3, the four sleeve plates 1003 are driven to slide upward, reducing the shaking caused by external factors and load offset.

[0022] A graphene layer is fixedly sleeved on the outer wall of the guide rod 1002. The graphene layer reduces the friction between the sleeve plate 1003 and the guide rod 1002, thereby improving the service life of the equipment.

[0023] A hoist 4 is fixedly connected to one side of the lower inner wall of the support frame 1. A hoisting wire 7 is wound around the winding end of the hoist 4. A first guide wheel 5 is fixedly connected to the interior of the support frame 1 at the upper end of the hoist 4. A second guide wheel 6 is fixedly connected to one side of the center of the upper inner wall of the support frame 1. The outer side of the hoisting wire 7 is attached to the outer side wall of the first guide wheel 5 and the second guide wheel 6 and extends to the lower part of the interior center of the support frame 1. A connecting buckle 8 is fixedly connected to the end of the wire 7. The connecting buckle 8 is fixedly connected to the hoisting frame 3. When the hoist 4 is started, the hoist 4 winds up the hoisting wire 7. After being guided by the first guide wheel 5 and the second guide wheel 6, the pulling force is turned upward, thereby pulling the hoisting frame 3 upward.

[0024] Working principle: In use, the bracket 1 and the high-stability base 2 are placed on the ground. One end of multiple counterweights 204 is inserted between the base frame 201 and the frame 202. With the setting of multiple balls 206, the counterweights 204 roll on the balls 206, which facilitates the movement of the balls 206 between the base frame 201 and the frame 202. This increases the overall weight of the high-stability base 2, lowers the center of gravity, and thus increases the stability of the equipment. The material is placed on the lifting frame 3, and then the lifting machine 4 is started. The lifting machine 4 winds up the hoisting wire 7, and after being guided by the first guide wheel 5 and the second guide wheel 6, the pulling force is turned upward, thereby pulling the lifting frame 3 upward. During the movement of the lifting frame 3, the four sleeve plates 1003 slide upward, reducing the shaking caused by external factors and load offset. In addition, the graphene layer reduces the friction between the sleeve plates 1003 and the guide rods 1002, improving the service life of the equipment.

[0025] After the material is lifted to the required height, control the hoist 4 to stop, then remove the material, control the hoist 4 to start in reverse, release the hoisting wire 7, and allow the hoisting frame 3 to descend slowly. The bottom of the hoisting frame 3 first contacts multiple air shock absorbers 902 and rubber pads 903 to reduce the impact force when the hoisting frame 3 descends, thereby increasing the service life of the hoisting frame 3.

[0026] After use, multiple counterweights 204 can be pulled out using handle 205. During the pulling process, the counterweights 204 roll along multiple balls 206, reducing friction and making it easier to remove the counterweights 204 for disassembly.

[0027] The equipment also includes an integrated controller for controlling the start and stop of the hoist 4 and detecting the operating status of the equipment. The integrated controller receives signals from various components through its input ports. These signals are processed and used as the basis for control decisions. The integrated controller then uses a control algorithm to process the input signals and generates control outputs according to predetermined rules. Based on the results of the control algorithm, the integrated controller sends signals to the actuators through its output ports. The integrated controller can coordinate the work of various components and continuously monitor the operating status of each component, adjusting the control strategy in a timely manner based on feedback to cope with possible changes or anomalies. This solution is a commonly used technical means in the prior art and will not be elaborated on further here.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
