Description

Technical Field

[0001] This utility model relates to the field of construction device technology, and in particular to an auxiliary device for concrete plastering construction. Background Technology

[0002] The traditional concrete pavement finishing process is as follows: After the concrete is poured and vibrated, workers use a wooden trowel for the first finishing, then grind it smooth with a grinder, and finally level it with a short wooden trowel. Before the concrete initially sets, a steel trowel is used for the second finishing, and after the concrete has initially set, the surface is roughened with a broom.

[0003] In the process of concrete plastering construction, lifting devices are required as an aid. For example, patent CN214423086U discloses a building concrete plastering construction auxiliary device, and CN209307814U discloses a concrete road surface plastering construction trolley. Such lifting auxiliary devices generally only have a lifting module to control the lifting of the surface, lack a safety protection module, and there is no guardrail above the device support plate. There are safety hazards for workers when working at heights, and their practicality is not high. Therefore, we propose a concrete plastering construction auxiliary device. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for concrete plastering construction, which solves the technical problem that existing auxiliary devices for concrete plastering construction lack safety protection structures, posing safety hazards to workers when working at heights.

[0005] To address the aforementioned problems, this utility model provides an auxiliary device for concrete plastering construction, comprising a base plate with several casters connected to its bottom. Fixing components for positioning are fixedly installed on both sides of the base plate. A height adjustment component and at least four sets of pneumatic rods are installed on the base plate. Both the height adjustment component and the pneumatic rods are connected to a support plate. The four sets of pneumatic rods are respectively connected to the four corners of the support plate. When the support plate rises, the pneumatic rods provide more support points, stabilizing the support plate and preventing deformation or breakage due to uneven weight distribution. When the height adjustment component fails, causing the support plate to fall, the pneumatic rods act as a buffer, providing a certain degree of safety protection. Guardrails are provided on the support plate.

[0006] According to one embodiment of the present invention, the height adjustment component includes a drive motor, a bidirectional lead screw assembly, a movable plate, and a lifting support rod. The bidirectional lead screw assembly is connected to the drive motor, and movable plates are respectively installed on both sides of the bidirectional lead screw assembly. The lifting support rod is hinged to the movable plate and the support plate.

[0007] According to one embodiment of the present invention, the bidirectional lead screw assembly is provided in two sets, namely a first bidirectional lead screw and a second bidirectional lead screw, which makes the lifting process more stable.

[0008] According to one embodiment of the present invention, the drive motor is provided in one or two sets.

[0009] According to one embodiment of the present invention, the guardrail is provided with a movable door and a door latch structure.

[0010] According to one embodiment of the present invention, the guardrail is composed of several parts, each of which can be detachably installed on the support plate. During construction, multiple sets of this device can be used to disassemble parts of the guardrail and build a platform on the support plate of the adjacent device, which facilitates construction.

[0011] According to one embodiment of the present invention, the fixing component includes a movable abutment plate, the bottom of which is provided with a plurality of protruding structures with pointed tips, so as to achieve a fixing effect by contacting the abutment plate with the ground.

[0012] According to one embodiment of the present invention, the fixing component further includes an electric push rod, which is connected to the abutment plate, or the abutment plate can be driven by a hydraulic cylinder.

[0013] According to one embodiment of the present invention, at least two sets of fixing components are provided and symmetrically arranged on both sides of the base plate to achieve a stable support effect.

[0014] The beneficial effects of this utility model are that when the height of the support plate needs to be adjusted, the height adjustment component is activated to raise the support plate to a suitable height, facilitating construction work. During this process, the pneumatic rods are connected to the four corners of the support plate. As the support plate rises, the pneumatic rods provide more support points, stabilizing the support plate and preventing deformation or breakage due to uneven weight distribution, thus ensuring safety during construction. When the height adjustment component fails or the structure is damaged, causing the support plate to fall, the gas inside the pneumatic rod is compressed, and the pneumatic rod acts as a buffer, providing a certain degree of safety protection. Furthermore, railings are also provided to further ensure safety. Attached Figure Description

[0020] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0021] Example 1:

[0022] A concrete plastering construction auxiliary device, such as Figures 1-4 As shown, the system includes a base plate 1, with casters 101 fixedly connected to its bottom. Fixing components 4 are fixedly installed on both sides of the base plate 1. Two fixing plates 102 are fixedly installed on the top of the base plate 1. A height adjustment component 5 is provided between the two fixing plates 102. Gas springs 59 are fixedly connected to the four corners of the top of the base plate 1. Support plates 2 are fixedly connected to the top of the four gas springs 59. A guardrail 3 is fixedly installed on the top of the support plate 2. A movable door 6 is movably connected to one side of the guardrail 3. A latch structure 7 is provided between the movable door 6 and the guardrail 3.

[0023] The fixing component 4 includes a fixing block 42, which is fixedly installed on both sides of the base plate 1. An electric push rod 41 is fixedly installed on the top of the fixing block 42. An abutment plate 43 is fixedly connected to the movable end of the electric push rod 41. The bottom of the abutment plate 43 is provided with several protruding structures with pointed tips. Opening the electric push rods 41 on both sides makes the abutment plate 43 fit tightly against the ground, thereby achieving the fixing of the device.

[0024] The height adjustment component 5 can be a lifting drive component such as an electric cylinder or a hydraulic cylinder.

[0025] The latch structure 7 includes a plug 71, which is fixedly installed in the middle of one side of the movable door 6. One end of the plug 71 has a positioning hole 72. A connecting block 73 is fixedly installed on the side of the guardrail 3 near the positioning hole 72. A pin 74 is inserted into the connecting block 73. A spring 75 is arranged around the surface of the pin 74. A baffle 76 is fixedly fitted onto the bottom surface of the pin 74. A slot 77 is provided in the middle of the connecting block 73. Figure 4As shown, when the operator opens the movable door 6, they enter the support plate 2 from here, pull the latch 74 upwards and close the movable door 6, so that the positioning hole 72 is inside the slot 77. When the operator stops pulling the latch 74, the latch 74 enters the positioning hole 72 under the action of the spring 75 and the baffle 76, thus completing the fixation of the movable door 6.

[0026] In the specific implementation process, the device is placed at the area requiring surface preparation under the guidance of the casters 101. The electric push rods 41 on both sides are activated to make the abutment plate 43 press tightly against the ground, thus fixing the device. The operator opens the movable door 6 to enter above the support plate 2, pulls the latch 74 upwards, and closes the movable door 6, so that the positioning hole 72 is inside the slot 77. Pulling the latch 74 stops, and at this time, the latch 74, under the action of the spring 75 and the baffle 76, enters the positioning hole 72, thus completing the fixing of the movable door 6. When it is necessary to adjust the support plate 2... When adjusting the height, the height adjustment component 5 is activated. The four sets of pneumatic rods 59 are connected to the four corners of the support plate 2. When the support plate 2 rises, the pneumatic rods 59 provide more support points, which helps to stabilize the support plate 2 and prevent deformation or breakage of the support plate 2 due to uneven weight distribution, thus ensuring the safety of the construction process. When the height adjustment component 5 fails or is damaged, causing the support plate 2 to fall, the gas inside the pneumatic rods 59 is compressed, and the pneumatic rods 59 act as a buffer, providing a certain degree of safety protection.

[0027] The drive motor 51 drives the first bidirectional lead screw 52 and the drive gear 55 to rotate. At the same time, the rotation of the drive gear 55 drives the chain 54 and the driven gear 56 to rotate. The rotation of the driven gear 56 drives the second bidirectional lead screw 53 to rotate. At this time, the moving plates 57 on the surfaces of the first bidirectional lead screw 52 and the second bidirectional lead screw 53 approach each other. The moving plates 57 apply an upward force to the rotating rod 58, causing the rotating rod 58 to push the support plate 2 to rise. Meanwhile, the pneumatic rod 59 can make the support plate 2 more stable during the lifting process.

[0028] Example 2:

[0029] Based on Embodiment 1, the height adjustment component 5 includes a drive motor 51, which is fixedly installed on one side of the fixed plate 102. The first bidirectional lead screw 52 and the second bidirectional lead screw 53 are threadedly connected to two sets of moving plates 57. The drive motor 51 (which can be used with a reduction gearbox) drives the two sets of second bidirectional lead screws 53 to rotate through the belt transmission mechanism 56. In other embodiments, the drive can also be achieved by setting a gear transmission or by connecting each lead screw to a motor.

[0030] Multiple rotating rods 58 are rotatably connected to the top of the two sets of movable plates 57. The rotating rods 58 are rotatably connected to the bottom of the support plate 2. The rotating rods 58 can be arranged to cross and intersect each other, or they can not cross and only be connected to the movable plates 57 and the support plate 2.

[0031] When the height of the support plate 2 needs to be adjusted, the drive motor 51 is turned on. The drive motor 51 drives the first bidirectional lead screw 52 and the second bidirectional lead screw 53 to rotate through the belt transmission mechanism 56. The moving plates 57 move closer to each other and apply an upward force to the rotating rod 58, so that the rotating rod 58 pushes the support plate 2 to rise. At the same time, the pneumatic rod 59 can make the support plate 2 more stable during the lifting process.

[0032] Example 3:

[0033] Based on embodiment 1 or 2, the guardrail 3 is composed of several parts, each of which can be detachably installed on the support plate 2. During construction, multiple sets of this device can be used to disassemble parts of the guardrail 3 and build a platform on the support plate 2 of the adjacent device to facilitate construction.

[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
