Description

Technical Field

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

[0002] During construction, it is often necessary to transport building materials vertically. Portable material lifting equipment is therefore widely used. This type of equipment mainly consists of a mounting frame, a placement platform, and a winch. Through their coordinated work, the placement platform is raised and lowered, and the building materials are placed on the placement platform for lifting and feeding.

[0003] Currently, most material lifting equipment uses horizontal platforms, which meet basic requirements for transporting most conventional building materials such as blocks and slabs. However, when it comes to transporting building pipes, horizontal platforms have significant drawbacks. Due to the special shape of the pipes, ropes are usually used to tie and secure them during the lifting and feeding process to ensure their transport stability. This operation adds a cumbersome binding step before material handling. Moreover, after the pipes are lifted to a high position, operators need to climb back to the corresponding height to untie the ropes before the pipes can be unloaded smoothly. This is not only troublesome to operate but also poses certain safety risks, reduces construction efficiency, and affects the construction progress. In view of this, we propose a portable material lifting device for building construction. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a portable material lifting device for construction, so as to solve the technical problem that the current material lifting device is not convenient for pipeline transportation.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features a first groove on the top of a placement platform, within which a placement plate is rotatably arranged, with its top flush with the top of the platform. A jacking structure is then positioned at the center of the platform's bottom. Therefore, during construction, when lifting and feeding block-shaped building materials, the placement plate can be kept horizontally within the first groove, ensuring the entire platform remains level and facilitating the lifting and feeding of these materials. When transporting pipe materials, the jacking structure lifts one side of the placement plate, forming a triangular groove on the top of the platform. Once the pipe is placed, its weight and the wall of the triangular groove provide stable positioning, preventing forward and backward movement and ensuring stability during transport. After the pipe is lifted to the appropriate position, simply lowering the placement plate allows for quick unloading. This significantly improves the convenience and stability of pipe transport, solving the technical problem of current material lifting equipment's inconvenience in pipe transport. Therefore, this utility model offers the advantage of more convenient and stable lifting and feeding of pipe materials.

An inclined seat is provided in the center of one side of the bottom of the adjustable plate frame, and a docking slot is opened on the inclined seat. The docking slot is then connected to the pushing structure. Therefore, when the pushing structure pushes one side of the placement plate to rise, the adjustable plate frame will rotate 90 degrees counterclockwise with the cooperation of the inclined seat and the docking slot, and then lift one side of the placement plate until a triangular groove is formed at the top of the placement platform. At this time, the top edge of the placement plate will form a shielding edge with the cooperation of the adjustable plate frame, which can shield and limit the pipe in the triangular groove, effectively preventing the top pipe in the triangular groove from falling, thus further ensuring the stability of the pipe construction material transportation.

[0025] like Figures 1 to 8 As shown, this utility model relates to a portable material lifting device for construction, including a mobile base 1, a rectangular mounting frame 2 vertically arranged on the top of the mobile base 1, a sleeve plate 3 slidably arranged inside the rectangular mounting frame 2, a placement platform 7 arranged on one side of the sleeve plate 3, fixed pulleys 6 symmetrically arranged on the top of the rectangular mounting frame 2, a winch 4 arranged on the top of the mobile base 1 facing away from the placement platform 7, two sets of symmetrical steel wire ropes 5 arranged on the winch 4, the steel wire ropes 5 being connected to the sleeve plate 3 through the free end of the fixed pulleys 6, a first groove 705 opened on the top of the placement platform 7, a placement plate 9 rotatably arranged in the first groove 705, the top of the placement plate 9 being flush with the top of the placement platform 7, a pushing structure 8 arranged at the bottom of the placement platform 7, and a side plate 701 vertically arranged on the top of the placement platform 7 facing the rectangular mounting frame 2, the side plate 701 and the placement platform 7 forming an L-shape.

[0026] In construction, when it is necessary to lift and feed block-shaped building materials, the placement plate 9 can be kept horizontally in the first groove 705 to ensure that the entire placement platform 7 is horizontal, which facilitates the lifting and feeding of block-shaped building materials. When transporting pipe building materials, the jacking structure 8 is used to lift one side of the placement plate 9, so that the top of the placement platform 7 forms a triangular groove. After the pipe is placed, it can achieve stable positioning by squeezing against the wall of the triangular groove under its own weight, avoiding back-and-forth movement and ensuring the stability of the transportation process. When the pipe is lifted to the appropriate position, the placement plate 9 can be laid flat to quickly unload the pipe, which significantly improves the convenience and stability of the equipment for pipe transportation.

[0027] Specifically, the rectangular mounting frame 2 has symmetrically arranged grooves 201 on one side facing the placement platform 7, and the side plate 701 has symmetrically arranged welding strips 702 on the side facing the rectangular mounting frame 2. Several sets of equidistant balls 703 are rolled on the welding strips 702, and the balls 703 are located in the grooves 201. The balls 703 on the welding strips 702 roll and rub against the grooves 201, which mainly serves to support the side plate 701, thereby ensuring that the side plate 701 can be raised and lowered stably, and avoiding excessive friction between the side plate 701 and the rectangular mounting frame 2, or even jamming.

[0028] In this embodiment of the present invention, a second groove 901 is provided on the top of the placement plate 9 facing away from the rectangular mounting bracket 2. A second rectangular opening 902 is provided at the center of the bottom of the second groove 901. An adjustable plate frame 10 is hinged inside the second groove 901. The top of the adjustable plate frame 10 is flush with the top of the placement plate 9. An inclined seat 11 is provided at the center of the bottom of the adjustable plate frame 10 facing the rectangular mounting bracket 2. The inclined seat 11 passes through the second rectangular opening 902 and faces away from the adjustable plate. A docking slot 1101 is provided on one side of the frame 10. The pushing structure 8 includes an electric hydraulic push rod 802, the piston end of which is rotatably arranged in the docking slot 1101. A first rectangular opening 704 is provided in the center of the bottom of the placement platform 7, and the first rectangular opening 704 is connected to the first groove 705. A concave frame 801 is symmetrically arranged at the bottom of the placement platform 7 with the first rectangular opening 704. The cylinder end of the electric hydraulic push rod 802 is rotatably arranged in the concave frame 801. The electric hydraulic push rod 802 is arranged at an angle.

[0029] When the electric hydraulic push rod 802 pushes one side of the placement plate 9 to rise, the adjustable plate frame 10 will rotate 90 degrees counterclockwise with the cooperation of the tilting seat 11 and the docking slot 1101, and then lift one side of the placement plate 9 until a triangular groove is formed at the top of the placement platform 7. At this time, the top edge of the placement plate 9 will form a blocking edge with the cooperation of the adjustable plate frame 10, which can block and limit the pipe in the triangular groove, effectively preventing the top pipe in the triangular groove from falling, thus further ensuring the stability of the pipe construction material transportation.

[0030] Specifically, a preset gap 12 is reserved between the adjustable plate frame 10 and the second groove 901. The width of the preset gap 12 is the same as the height of the adjustable plate frame 10. The preset gap 12 is mainly to facilitate the adjustable plate frame 10 to rotate 90 degrees under the hinge.

[0031] Furthermore, the adjustable plate frame 10 includes a mounting plate 1001 and a mounting strip 1002. The mounting plate 1001 has several sets of equidistant cross grooves 1003 on the side facing the mounting strip 1002. The mounting strip 1002 has a cross rod 1004 corresponding to the cross grooves 1003 on the side facing the mounting plate 1001, and the cross rod 1004 is inserted into the cross groove 1003. An adjusting bolt 1005 is rotatably arranged in the center of one side of the mounting strip 1002, and the adjusting bolt 1005 is screwed into the mounting plate 1001. When transporting the pipeline, the adjusting bolt 1005 can be turned according to the diameter of the pipeline. At this time, the mounting strip 1002 and the cross rod 1004 will move outward, which can adjust the height of the retaining edge formed by the adjustable plate frame 10 at the top edge of the placement plate 9, so as to avoid the situation where the retaining edge is too low and cannot properly block and limit the pipeline.

[0032] Working principle: This embodiment provides a portable material lifting device for construction. First, during construction, when it is necessary to lift and feed block-shaped building materials, the placement plate 9 can be kept horizontally in the first groove 705 to ensure that the entire placement platform 7 is horizontal, which facilitates the lifting and feeding of block-shaped building materials. When transporting pipe building materials, the jacking structure 8 is used to lift one side of the placement plate 9, so that the top of the placement platform 7 forms a triangular groove. After the pipe is placed, it can achieve stable positioning by squeezing against the wall of the triangular groove under its own weight, avoiding back-and-forth movement and ensuring the stability of the transportation process. When the pipe is lifted to the appropriate position, the placement plate 9 can be laid flat to quickly unload the pipe, which significantly improves the convenience and stability of the equipment for pipe transportation.

[0033] Secondly, when the electric hydraulic push rod 802 pushes one side of the placement plate 9 to rise, the adjustable plate frame 10 will rotate 90 degrees counterclockwise with the cooperation of the tilting seat 11 and the docking slot 1101, and then lift one side of the placement plate 9 until a triangular groove is formed at the top of the placement platform 7. At this time, the top edge of the placement plate 9 will form a blocking edge with the cooperation of the adjustable plate frame 10, which can block and limit the pipe in the triangular groove, effectively preventing the top pipe in the triangular groove from falling, thus further ensuring the stability of the pipe construction material transportation.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
