Description

Technical Field

[0001] The invention belongs to the technical field of auxiliary equipment for building construction, and particularly relates to a light-duty wall-building and plastering material-lifting device. Background Art

[0002] In existing wall plastering, masons usually smooth the cement mortar poured on the brick surface with a trowel. The speed and quality of construction depend on the proficiency of the masons and the supply speed of the cement mortar. Generally, skilled masons have faster construction speeds and correspondingly higher requirements for the supply speed of materials. When plastering relatively flat and high walls, the lifting and transportation of some light materials are often affected by the indoor space, transportation efficiency, and the bearing capacity of the work surface. Too much material cannot be placed on the work surface, and large vertical transportation equipment cannot be used, resulting in low material transportation efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a lightweight material lifting device for wall plastering to solve the problem in the background art that the lifting of materials during wall plastering is affected by the indoor space, resulting in low transportation efficiency.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0005] A light-duty wall-building and plastering material lifting device comprises a scaffolding provided on the construction surface of the plastered wall, a base provided below the construction surface of the plastered wall, a supporting pipe provided vertically on the base, a cantilever rod provided rotatably on the top of the supporting pipe rod, the cantilever rod being driven to rotate by pulling a steel wire rope provided on the cantilever rod, a pulley being suspended on the cantilever rod, a steel wire rope being movably connected to the pulley, one end of the steel wire rope being connected to the material to be lifted, and the other end being connected to the output end of a winch provided on the base;

[0006] The side wall of the support tube is provided with an auxiliary rod for limiting the second steel rope, and the second steel rope is sleeved on the end of the auxiliary rod away from the support tube, and the auxiliary rod includes an axle seat fixedly connected to the side of the support tube, an outer shaft provided on the axle seat, an inner shaft one end of which is sleeved on the outer shaft, and a ring provided at the other end of the inner shaft and used to limit the second steel rope, wherein a limiting groove is provided on the inner side wall of the outer shaft, and the inner shaft is slidably arranged in the limiting groove by a slider fixedly connected thereto, and a damping spring is provided between the side of the slider and the inner wall of the limiting groove.

[0007] As a further optimization scheme of the present invention, the supporting pipe includes a straight pipe and a rotating rod inserted into the straight pipe. Several bearings are provided between the side of the rotating rod and the straight pipe. The upper end of the rotating rod is connected to the cantilever rod through a rotating grinding disc.

[0008] As a further optimization solution of the present invention, the straight pipe and the base are supported and fixed by a plurality of connecting rods.

[0009] As a further optimization scheme of the present invention, the steel wire rope 2 is provided with marking point 1 and marking point 2 near one end of the material to be lifted. During the lifting process, when marking point 1 reaches a pulley, the lifting is stopped. The stroke between marking point 1 and marking point 2 is the stroke of the steel wire rope 2 required to rotate and transfer the material.

[0010] As a further optimization scheme of the present invention, the outer wall of the straight pipe is provided with pulley 2 and pulley 3, the straight pipe is connected to the axle seat through a mounting seat, a pulley 4 is provided on the outside of the mounting seat, and the wire rope 1 is connected to the rope lock through pulley 3, pulley 4 and pulley 2 in sequence.

[0011] As a further optimization scheme of the present invention, the mounting seat is provided with a limiting slide toward the direction of the straight pipe, and the side wall of the straight pipe is provided with a cutting groove that cooperates with the movement of the limiting slide. A strip groove is provided in the mounting seat along the horizontal direction, and a limiting pin is slidably connected in the strip groove. A damping spring 2 is provided between the limiting pin and the inner wall of the strip groove, and an abutting inclined surface is provided at the lower end of the limiting pin. The fixed shaft end of the pulley four is connected to a push rod, and when the steel wire rope pulls the pulley four to rise, the upper end of the push rod cooperates with and abuts the abutting inclined surface.

[0012] As a further optimization solution of the present invention, the side of the straight pipe is provided with an extrusion surface that cooperates with the limit pin to press, and the extrusion surface and the end of the limit pin are both provided with anti-slip textures.

[0013] As a further optimization solution of the present invention, the supporting pipe is fixed to the plastered wall through a plurality of parallel wall connecting members.

[0014] The beneficial effects of the present invention are:

[0015] 1) The present invention can lift materials to a designated working surface on a scaffold through the cooperation of a pulley and a winch, which is not affected by the size of the indoor space and can ensure high lifting efficiency. At the same time, the rotation effect of the support pipe and the cantilever rod rotatably arranged on the top of the support pipe is combined with the rotation effect of the cantilever rod, so that the material can be transferred to the scaffold by pulling the cantilever rod. The entire device occupies a small area and is easy to operate.

[0016] 2) The present invention improves the stability of the second steel wire rope during the material lifting and transfer processes by providing an auxiliary rod. The outer shaft and the inner shaft are connected to each other, and when the second steel wire rope shakes, the damping spring 1 can act as a buffer, making the second steel wire rope tend to be stable, thereby preventing the material from shaking significantly due to errors during operation by workers.

[0017] 3) The present invention provides a mounting seat at the connection between the auxiliary rod and the supporting pipe, and cooperates with the labor-saving pulley group composed of pulley three, pulley four, and pulley two. This not only ensures that the auxiliary rod can always provide a limit for the wire rope two during the horizontal transfer of materials to prevent it from shaking, but also can reduce the instantaneous force when pulling the lifting handle to rotate the cantilever rod, making it more convenient for workers to transfer materials to the work surface.

DETAILED DESCRIPTION

[0025] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Example 1

[0027] like Figure 1-6 As shown, a lightweight wall plastering material lifting device includes a scaffold 2 provided on the construction surface of a plastered wall 1, the height of the scaffold 2 being adaptively adjusted according to the height of the construction surface, and also includes a base 4 provided below the construction surface of the plastered wall 1, the base 4 being vertically provided with a support pipe 6, the top of the support pipe 6 being rotatably provided with a cantilever rod 7, the cantilever rod 7 being driven to rotate by pulling a steel wire rope 26 provided on the cantilever rod 7, a pulley 10 being suspended on the cantilever rod 7, a steel wire rope 2 9 being movably connected to the pulley 10, one end of the steel wire rope 2 9 being connected to a material to be lifted 11, and the other end being connected to the output end of a winch 8 provided on the base 4;

[0028] When in use, first start the winch 8 to lift the material to the construction surface of the designated scaffold, and then pull the lifting handle 15 provided on the wire rope 26 to pull the cantilever rod 7 to rotate, and then transfer the material to the construction site on the scaffold 2.

[0029] The side wall of the support tube 6 is provided with an auxiliary rod 14 for limiting the wire rope 29. The wire rope 29 is sleeved on the end of the auxiliary rod 14 away from the support tube 6. The auxiliary rod 14 includes an axle seat 141 fixedly connected to the side of the support tube 6, an outer shaft 142 provided on the axle seat 141, an inner shaft 143 with one end sleeved on the outer shaft 142, and a ring 144 provided at the other end of the inner shaft 143 and used to limit the wire rope 29. The inner side wall of the outer shaft 142 is provided with a limiting groove 1421, and the inner shaft 143 is slidably provided in the limiting groove 1421 through a slider 1431 fixedly connected thereto, and a damping spring 1432 is provided between the side of the slider 1431 and the inner wall of the limiting groove 1421.

[0030] The setting of the auxiliary rod in the present application can improve the stability of the wire rope 29 during the material lifting and transfer processes. By setting the outer shaft 142 and the inner shaft 143 that are connected to each other, and when the wire rope 29 shakes, the damping spring 1432 can play a buffering role, so that the wire rope 29 tends to be stable, preventing the material from shaking drastically due to mistakes made by workers during operation.

[0031] In order to further improve the rotation stability of the cantilever rod 7, the supporting pipe 6 includes a straight pipe 61 and a rotating rod 62 inserted into the straight pipe 61. Several bearings 63 are provided between the side of the rotating rod 62 and the straight pipe 61. The upper end of the rotating rod 62 is connected to the cantilever rod 7 through a rotating grinding disc 18.

[0032] In order to further improve the installation stability of the straight pipe 61 , the straight pipe 61 and the base 4 are supported and fixed by a plurality of connecting rods 5 .

[0033] In order to prevent the material from being unable to be transferred to the working surface when the cantilever rod 7 is rotated, a marking point 12 and a marking point 2 13 are provided on the end of the wire rope 2 9 near the material to be lifted 11. During the lifting process, when the marking point 12 reaches the pulley 10, the lifting is stopped. The stroke of the marking point 12 and the marking point 2 13 is the stroke of the wire rope 2 9 required for rotating and transferring the material.

[0034] In order to further improve the stability of the device during the process of pulling the wire rope 126 to transfer materials, the present application further optimizes the connection between the auxiliary rod 14 and the straight pipe 61. Specifically, the outer wall of the straight pipe 61 has a pulley 2 16 and a pulley 3 19. The straight pipe 61 is connected to the shaft seat 141 through a mounting seat. The outer side of the mounting seat is provided with a pulley 4 24. The wire rope 126 is connected to the rope buckle 17 through the pulley 3 19, the pulley 4 24, and the pulley 2 16 in sequence. The mounting seat is provided with a limiter toward the straight pipe 61. The limiting slide 25 and the side wall of the straight tube 61 are provided with a cutting groove 611 for cooperating with the movement of the limiting slide 25. A strip groove 20 is provided in the mounting seat in the horizontal direction. A limiting pin 21 is slidably connected in the strip groove 20. A damping spring 22 is provided between the limiting pin 21 and the inner wall of the strip groove 20. A contact slope 27 is provided at the lower end of the limiting pin 21. The fixed shaft end of the pulley four 24 is connected with the push rod 23. When the wire rope 26 pulls the pulley four 24 to rise, the upper end of the push rod 23 cooperates with the contact slope 27 to abut.

[0035] Specifically, the side of the straight tube 61 is provided with an extrusion surface 612 that cooperates with the limiting pin 21 to press, and the extrusion surface 612 and the end of the limiting pin 21 are both provided with anti-slip textures.

[0036] Specifically, the supporting pipe 6 is fixed to the plastered wall 1 through a plurality of parallel wall connecting members 3 .

[0037] When in use, by pulling the lifting handle 15, the wire rope 1 26 drives the pulley 4 24 to move up until the top rod 23 connected to the fixed shaft end of the pulley 4 24 abuts against the limit pin 21. Since the lower end of the limit pin 21 is provided with an abutting inclined surface 27, Figure 4It can be seen that pulley four 24 drives the top rod 23 to move upward, which will drive the limit pin 21 to move to the right. At this time, the damping spring two 22 is compressed, and the limit pin 21 is disengaged from the extrusion surface 612, so that the auxiliary rod 14 is released from the relatively fixed rotation state with the support pipe 6 as a whole. When the wire rope one 26 is pulled to drive the cantilever rod 7 to rotate, the pulley four 24 moves upward and drives the auxiliary rod 14 to rotate together with the wire rope two 9. This can ensure that the auxiliary rod 14 can always provide a limit for the wire rope two 9 during the material transfer process, preventing it from shaking; in addition, since the wire rope one 26 is connected to the rope buckle 17 through the pulley three 19, the pulley four 24, and the pulley two 16 in sequence, the pulley four 24 can move upward at the moment of starting to pull, then the pulley three 19, the pulley four 24, and the pulley two 16 form a labor-saving pulley group during the rotation of the device to transfer materials, so that the instantaneous force of pulling the lifting handle 15 is smaller.

[0038] It should be noted that the maximum weight of the material to be lifted in this application does not exceed 75kg.

[0039] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
