Description

Technical Field

[0001] This invention belongs to the field of building technology, and in particular relates to a chassis installation and dismantling device for a floor trowel and its usage method. Background Technology

[0002] Existing power trowels are widely used in the construction of concrete floors, epoxy and durable flooring in high-standard factories, warehouses, parking lots, plazas, and framed buildings. In the construction industry, power trowels are needed to smooth large areas of concrete floors to achieve a flat, smooth surface, meeting the requirements for subsequent laying of tiles, carpets, or other decorative materials. Currently, the two main types of power trowels are walk-in and ride-on. These types of power trowels have relatively limited functionality, primarily handling uneven surfaces, and suffer from a high rate of damage during use. Traditional power trowels are not designed with dedicated tools for changing the trowel chassis, making it difficult for operators to install and disassemble the chassis without external machinery, resulting in low operating efficiency. Furthermore, after completing segmented construction, the power trowel chassis needs to be disassembled for transportation to ensure it is not damaged during transport. Therefore, a new device is urgently needed to assist in the installation and disassembly of the power trowel chassis and improve the current situation. Summary of the Invention

[0003] In view of the above problems, the present invention provides a chassis mounting and dismounting device for a floor polishing machine and its usage method, so as to solve the above or other problems existing in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a chassis mounting and dismounting device for a floor polishing machine, comprising a main body, a support component connected to the main body, and a snap-fit ​​component connected to the main body. The support component and the snap-fit ​​component are respectively disposed on both sides of the main body, and the snap-fit ​​component is disposed near one end of the main body so that the snap-fit ​​component can snap-fit ​​with the floor polishing machine.

[0005] Furthermore, a snap-fit ​​groove is provided on the side of the snap-fit ​​component that is opposite to the main body.

[0006] Furthermore, the support components are positioned relative to the connectors.

[0007] Furthermore, the support assembly includes a connector and a support member disposed at one end of the connector. The other end of the connector is detachably connected to the main body. The connector is arranged along a first direction, and the support member is arranged along a second direction. The first direction and the second direction are perpendicular to each other.

[0008] Furthermore, the main body is set along a third direction, which is perpendicular to the plane containing the first and second directions.

[0009] Furthermore, the main body includes a main upright, a handrail connecting rod located at one end of the main upright, and a handrail connecting rod connected to the handrail connecting rod. The handrail connecting rod intersects with the main upright, and the handrail connecting rod and the snap-fit ​​are located on the same side of the main upright.

[0010] Furthermore, both the snap-fit ​​connector and the support assembly are located on the side wall of the main upright near the end where the handrail connecting rod is not installed.

[0011] Furthermore, the handrail and the handrail connecting rod are set vertically.

[0012] Furthermore, the main uprights, handrail connecting rods, and handrail rods are all rod structures.

[0013] A method for using a chassis mounting and dismounting device for a floor polishing machine includes the following steps:

[0014] At any point on the floor trowel, engage the locking mechanism with the edge of the floor trowel, make the support components contact the ground, apply force to the main body, and lift the floor trowel from this point.

[0015] Place an auxiliary pad on the raised part of the floor polisher;

[0016] Remove the chassis mounting and disassembly device of the floor polisher; in this position, the floor polisher is supported by an auxiliary pad.

[0017] Repeat the above steps, raising the floor polisher from different positions along its circumferential direction.

[0018] Due to the adoption of the above technical solution, the chassis installation and dismantling device of the floor trowel is simple, practical and convenient in structure. It has a snap-fit ​​component, which allows the device to snap onto the edge of the floor trowel. It also has a support component, which can contact the ground and act as a fulcrum, allowing the device to rotate around the support component and apply force to one end of the main body, which can lift the floor trowel. This enables the rapid installation and dismantling of the floor trowel chassis, effectively solving the problems of difficult disassembly of the chassis when the floor trowel fails and the difficulty in disassembling the chassis before transporting the floor trowel in traditional construction methods, which affect the construction period and construction quality.

[0019] The chassis mounting and dismantling device for this floor trowel operates on the principle of leverage. It uses snap-fit ​​slots to secure the floor trowel and the device to the corners. By pressing down on the main body, one end of the floor trowel can be lifted. An auxiliary pad is then used to elevate the trowel. This method allows for operation in other directions, enabling the entire floor trowel to be raised. This provides operators with space at the bottom for installation and dismantling, replacing the traditional method where chassis installation and dismantling lacks operational space and requires external lifting. This significantly improves dismantling speed, and the device's structure makes it easy to carry. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Figure 1 The diagram illustrates a structural schematic of an embodiment of the present invention. This embodiment relates to a chassis installation and dismantling device for a floor trowel and its usage method. It is used for the installation, dismantling, and maintenance of the chassis of a floor trowel. By using this chassis installation and dismantling device, the entire floor trowel can be erected, creating a space between the floor trowel and the ground for operators and machinery to enter and install and dismantle the chassis. This solves the problem of insufficient operating space for chassis installation and dismantling in traditional construction, requiring the use of external machinery for lifting. It improves the chassis dismantling speed, has a simple structure, and is easy to carry.

[0025] A mounting and dismounting device for a floor polishing machine chassis, such as Figure 1 As shown, the device includes a main body, a support component connected to the main body, and a snap-fit ​​component 4 connected to the main body. The main body serves as a supporting frame, facilitating the installation of the support component and snap-fit ​​component 4. The support component is used to contact the ground, and the snap-fit ​​component 4 is used to snap onto the floor trowel. The support component and snap-fit ​​component 4 are respectively located on both sides of the main body, with the snap-fit ​​component 4 located near one end of the main body. This allows the snap-fit ​​component 4 to snap onto the floor trowel, and the support component does not interfere with the snap-fit ​​action of the snap-fit ​​component 4 onto the floor trowel. It also facilitates contact between the support component and the ground, so that when the floor trowel chassis installation and removal device is in use, the contact point between the support component and the ground is the force point or fulcrum, applying force to the end of the main body away from where the snap-fit ​​component 4 is located, tilting the floor trowel so that the chassis of the floor trowel is away from the ground, creating space for the installation, disassembly, and maintenance of the chassis.

[0026] The aforementioned snap-fit ​​component 4 has a snap-fit ​​groove on its side facing away from the main body. The snap-fit ​​groove is used to snap into the edge of the floor polisher. The edge of the floor polisher is inserted into the snap-fit ​​groove, connecting the device to the floor polisher so that the operator can lift the entire floor polisher by operating the device. The snap-fit ​​component 4 can be a block structure, with the side of the snap-fit ​​component 4 not connected to the main body recessed towards the main body to form the snap-fit ​​groove. Alternatively, the snap-fit ​​component 4 can be a plate structure, bent to make its cross-sectional shape arc or polygon, constructing a groove structure to form the snap-fit ​​groove. The structure of the snap-fit ​​component 4 can be selected and set according to actual needs, and no specific requirements are specified here.

[0027] Along the axial direction of the locking groove, both ends of the locking groove are connected to the outside, and the locking groove has a certain depth so that it can engage with the edge of the floor polisher without being limited by the length of the edge of the floor polisher. The cross-sectional shape of the locking groove is adapted to the cross-sectional shape of the edge of the floor polisher so that when the locking piece 4 engages with the edge of the floor polisher, the edge of the floor polisher can fit against the inner surface of the locking groove, increasing the contact area between the locking piece 4 and the edge of the floor polisher. This allows the locking piece 4 to apply force to the edge of the floor polisher, thereby enabling one side of the floor polisher to be lifted from the contact position without damaging the edge of the floor polisher.

[0028] The aforementioned support component and the snap-fit ​​part 4 are arranged opposite each other, and the axes of the support component and the snap-fit ​​part 4 are arranged opposite each other to the main body, so that the support component can serve as a fulcrum to realize the transmission of the force applied by the device to the floor polisher.

[0029] The aforementioned support assembly includes a connector 6 and a support member 3 located at one end of the connector 6. The connector 6 is used to connect the support member 3 to the main body, and the other end of the connector 6 is detachably connected to the main body, thereby making the support assembly detachably connected to the main body. When the device is not in use, the support assembly can be detached from the main body for storage and placement, making the device easy to carry. When the device is in use, the support assembly is installed together with the main body for use, making the device easy to carry and use, thus improving the portability of the device. The connector 6 can be connected to the main body by thread, plug, snap, bolt, or other detachable connection methods, depending on actual needs. No specific requirements are specified here.

[0030] The aforementioned connector 6 is a rod structure, and the aforementioned support 3 is also a rod structure. The connector 6 is arranged along a first direction, and the support 3 is arranged along a second direction. The first direction and the second direction are perpendicular to each other, that is, the connector 6 and the support 3 are located on the same plane and are perpendicular to each other. The support 3 is fixedly installed at one end of the connector 6, and the support 3 and the connector 6 are fixedly connected. This fixed connection can be achieved by using bolts or other connectors 6, welding, riveting, or other fixed connection methods, depending on actual needs. No specific requirements are specified here. The middle part of the connector 6 and the support 3 are fixedly connected, and the connector 6 and the support 3 form a T-shaped support assembly. The support 3 is in contact with the ground and serves as the fulcrum when the entire device applies force to the floor polisher.

[0031] The cross-sectional shape of the connector 6 and the support 3 can be circular, square, or other shapes, depending on the actual needs. No specific requirements are specified here.

[0032] The aforementioned main body is positioned along a third direction, which is perpendicular to the plane containing the first and second directions. That is, the main body is perpendicular to the plane containing the connector 6 and the support 3. The main body is perpendicular to both the connector 6 and the support 3, and the other end of the main body is connected to the connector 6. This main body has a certain length to allow the operator to apply force to it, causing it to rotate around the support assembly and apply a force to the floor polisher, lifting one side of it. The length of this main body is selected based on actual needs and is not specifically required here.

[0033] The main body includes a main upright 2, a handrail connecting rod 5 located at one end of the main upright 2, and a handrail rod 1 connected to the handrail connecting rod 5. The main upright 2 serves to support the frame, facilitating the installation of the handrail connecting rod 5 and the handrail rod 1, as well as the installation of the support components and snap-fit ​​parts 4. The main upright 2 is a rod structure with a certain length, which can be selected according to actual needs; no specific requirements are specified here. Both the handrail connecting rod 5 and the handrail rod 1 are rod structures. One end of the handrail connecting rod 5 is fixedly connected to the handrail rod 1, and the handrail rod 1 is located at one end of the handrail connecting rod 5. The handrail connecting rod 5 and the handrail rod 1 are fixedly connected at the middle position. The handrail rod 1 and the handrail connecting rod 5 are arranged perpendicularly, forming a T-shaped handrail structure. The operator can hold the handrail rod 1 to apply force to the entire device. The other end of the handrail connecting rod 5 is fixedly connected to the end of the main upright 2 away from the end where the snap-fit ​​4 is located. The handrail connecting rod 5 intersects with the main upright 2. The handrail connecting rod 5 is inclined. The main upright 2 is set in a vertical direction. The handrail connecting rod 5 and the snap-fit ​​4 are located on the same side of the main upright 2. That is, the handrail connecting rod 5 extends inclinedly from the end of the main upright 2 toward the side where the snap-fit ​​4 is located. The angle between the handrail connecting rod 5 and the main upright 2 is greater than 90° and less than 180°, so that the operator can apply a downward force to the handrail 1.

[0034] The aforementioned snap-fit ​​component 4 and support assembly are both located on the side wall of the main upright 2 near the end where the handrail connecting rod 5 is not located. That is, the handrail connecting rod 5 and handrail 1 are located at one end of the main upright 2, and the snap-fit ​​component 4 and support assembly are located on the side wall of the main upright 2 near the other end. The snap-fit ​​component 4 and support assembly are respectively located on the two opposite sides of the main upright 2.

[0035] The main upright 2, handrail connecting rod 5 and handrail rod 1 mentioned above are all rod structures. The cross-sectional shape of the main upright 2, handrail connecting rod 5 and handrail rod 1 can be circular, square or other shapes, depending on the actual needs. No specific requirements are made here.

[0036] A method for using a chassis mounting and dismounting device for a floor trowel includes placing the device at different positions on the floor trowel, and then lifting the floor trowel from these positions to raise the entire machine, facilitating subsequent installation, disassembly, and maintenance of the chassis. The method comprises the following steps:

[0037] At any position on the floor trowel, engage the locking piece 4 with the edge of the floor trowel, and the support assembly contacts the ground. Apply force to the main body, and the floor trowel will be lifted from this position. When applying force to the main body, the operator holds the handle bar 1 and applies pressure downward and simultaneously away from the floor trowel. The main upright 2 rotates around the support assembly, and the locking piece 4 moves upward, thereby lifting the floor trowel from this position.

[0038] Place an auxiliary pad under the raised part of the floor polisher.

[0039] Remove the chassis mounting and dismantling device of the floor trowel. In this position, the floor trowel is raised by the auxiliary pad. There is a certain space between the part of the floor trowel in this position and the ground. The height of this space is determined by the thickness of the auxiliary pad.

[0040] Repeat the above steps, raising the floor trowel from different positions along its circumference. For example, place the floor trowel chassis mounting device in the second position, repeat the above steps to lift the second position, and place an auxiliary pad at the lifted position. Then, place the floor trowel chassis mounting device in the third position, repeat the above steps to lift the third position, and place an auxiliary pad at the lifted position. Continue in this manner until the entire floor trowel is raised. The entire floor trowel is supported by multiple auxiliary pads, creating a certain space between the chassis and the ground, allowing maintenance personnel and machinery to access the bottom of the floor trowel to disassemble the chassis and perform related bottom fault repairs.

[0041] Due to the adoption of the above technical solution, the chassis installation and dismantling device of this floor trowel is simple, practical, and convenient in structure. It features a snap-fit ​​component that allows the device to engage with the edge of the floor trowel, and a support component that contacts the ground. This support component acts as a fulcrum, allowing the device to rotate around it and apply force to one end of the main body, thus lifting the floor trowel. This enables rapid installation and dismantling of the floor trowel chassis, effectively solving the problems of difficult chassis disassembly in traditional construction methods, such as difficulty in disassembling the chassis during machine malfunctions and the difficulty in disassembling the chassis before transportation, which affect construction schedules and work efficiency. Regarding the quality issue, the chassis mounting and dismantling device for this floor trowel should utilize the lever principle. It uses snap-fit ​​slots to secure the floor trowel and the device to the corners. By pressing down on the main body, one end of the floor trowel can be lifted. An auxiliary pad can then be used to elevate the trowel. This method allows for operation in other directions, enabling the entire floor trowel to be raised. This provides operators with space at the bottom for installation and dismantling, replacing the traditional method where chassis installation and dismantling lacks operational space and requires external lifting. This significantly improves dismantling speed, and the device's structure makes it easy to carry.

All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
