Description

Technical Field

[0001] This application relates to the field of electromechanical pipeline installation, and in particular to an auxiliary construction device. Background Technology

[0002] Currently, there is no dedicated automated equipment for the installation of electromechanical piping on standard floors. Construction still relies on manual labor or other auxiliary devices, resulting in low efficiency and poor safety. Commonly used auxiliary devices are lifting equipment; however, existing lifting equipment on the market is limited by size and weight, making it unsuitable for use in construction elevators and inconvenient for transporting between construction sites. Therefore, auxiliary construction equipment for electromechanical piping installation needs to address these issues, adapt to the complex and changing construction environment, and reduce the intensity of manual labor. Utility Model Content

When the lifting frame is in the first retracted state, it is tilted relative to the body. Compared with the lifting frame being completely tilted down and in a horizontal state parallel to the body, the tilted retracted state reduces the requirements for the length direction of the body; that is, the dimension in the length direction of the body does not need to be designed to be greater than the height dimension of the lifting frame to accommodate the lifting frame. The dimension in the length direction of the body can be designed to be smaller, smaller than the height dimension of the lifting frame, thus meeting the usage requirements of entering a conventional construction elevator. During the process of retracting the lifting frame, the dimension in the height direction of the auxiliary construction device is also reduced, so that the dimension in the height direction of the auxiliary construction device in the retracted state is also reduced, which can meet the usage requirements of entering a conventional construction elevator.

[0011] According to the auxiliary construction device of the first aspect of this application, the control cabinet is fixed to one end of the machine body, and a stop is provided on the side of the control cabinet. When the lifting frame is in the first storage state, the second end of the lifting frame abuts against the stop.

[0012] According to the auxiliary construction device of the first aspect of this application, the first movable tilting mechanism can drive the lifting frame to switch between the first storage state and the first working state.

[0013] According to the auxiliary construction apparatus of the first aspect of this application, the second moving tilting mechanism can drive the support plate to switch between the second storage state and the second working state.

[0015] According to the auxiliary construction device of the first aspect of this application, the hydraulic motor is further used to provide power to the first moving tilting mechanism and / or the second moving tilting mechanism, and to control the movement state of the lifting frame and / or the support plate.

[0016] According to the auxiliary construction device of the first aspect of this application, the lifting frame includes a first frame and a second frame, wherein the second frame is sleeved inside the first frame and can extend relative to the first frame.

One end of the steering shaft is fixed to the wheel frame, and the other end is fixed to the machine body. The drive wheels are installed inside the wheel frame. Each end of the steering linkage is connected to a wheel frame, so that the two drive wheels move synchronously.

[0018] According to the first aspect of the present application, the auxiliary construction device further includes a hydraulic control system and an electrical control system. The hydraulic control system is used to control the hydraulic motor, and the electrical control system is used to control the movement of at least one component among the first moving tilting mechanism, the lifting frame, and the fork assembly in the auxiliary construction device.

[0035] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0036] This application provides an auxiliary construction device related to the field of electromechanical pipeline installation, which assists in the transportation and lifting of pipeline materials during the installation process. It is understood that the auxiliary construction device needs to be used at different construction sites, thus requiring transfer between them. Currently, commonly available auxiliary construction devices are relatively large, and when transferred between different construction sites, they may not be able to fit into construction elevators. To address this issue, this application provides an auxiliary construction device with a smaller external size in the transfer state, enabling it to fit into common construction elevators while meeting the automation requirements of different construction environments.

[0037] refer to Figure 1 and Figure 2 The auxiliary construction device provided in this application includes a machine body 100, a first moving tilting mechanism 200, a lifting frame 300, a fork assembly 400, and a control cabinet 500. The first moving tilting mechanism 200 is capable of moving in the horizontal direction of the machine body 100. The first end of the lifting frame 300 is rotatably connected to the first moving tilting mechanism 200. The lifting frame 300 has a first retracted state tilted relative to the machine body 100 and a first working state perpendicular to the machine body 100. The fork assembly 400 is connected to the lifting frame 300 and is capable of moving up and down relative to the lifting frame 300.

[0038] It should be noted that, Figure 1 This diagram shows the structure of the auxiliary construction device of this application in the transfer state. Figure 2A schematic diagram of the auxiliary construction device of this application in its working state is shown. When the auxiliary construction device needs to be transferred between different construction sites, it is adjusted to a transfer state. At this time, the lifting frame 300 is in a first retracted state, tilted relative to the body 100. After the auxiliary construction device is transferred to the construction site, it unfolds... Figure 2 The working state shown is used for material transportation and lifting. At this time, the lifting frame 300 is in the first working state, which is perpendicular to the machine body 100.

[0039] Understandably, reference Figure 1 , Figure 1 In this application, the horizontal direction represents the length of the body 100, and the vertical direction represents the height of the body 100. The first end of the lifting frame 300 is rotatably connected to the first moving tilting mechanism 200. The rotation of the lifting frame 300 relative to the first moving tilting mechanism 200 enables the lifting frame 300 to switch between a first working state and a first retracted state. When the lifting frame 300 is in the first retracted state, it is tilted relative to the body 100. Compared to the lifting frame 300 being completely tilted down and parallel to the body 100, the tilted retraction method reduces the requirements on the length of the body 100; that is, the length dimension of the body 100 does not need to be designed to be greater than the height dimension of the lifting frame 300 to accommodate it. The length dimension of the body 100 can be designed to be smaller, less than the height dimension of the lifting frame 300, thus meeting the requirements for use in conventional construction elevators.

[0040] It is understood that by designing the first moving tilting mechanism 200 in this application, the lifting frame 300 can rotate relative to the body 100, thereby realizing the storage of the lifting frame 300. In the process of storing the lifting frame 300, the dimensions of the auxiliary construction device in the height direction are reduced, so that the dimensions of the auxiliary construction device in the height direction in the stored state are also reduced, which can meet the usage requirements of entering a conventional construction elevator.

[0041] As an example, refer to Figure 1 and Figure 2 The fork assembly 400 of the auxiliary construction device includes a second tilting mechanism 410 and a support plate 420. The second tilting mechanism 410 is capable of moving up and down relative to the lifting frame 300. This application incorporates a second tilting mechanism 410, and the support plate 420 is connected to the lifting frame 300 via the second tilting mechanism 410. The support plate 420 is rotatable relative to the second tilting mechanism 410, thus allowing the support plate 420 to have a second stowed state tilted relative to the lifting frame 300 and a second working state perpendicular to the lifting frame 300.

[0042] Figure 2When the auxiliary construction device is in operation, the support plate 420 is in a second operating state, perpendicular to the lifting frame 300. The support plate 420 of the fork assembly 400 is used to support and fix materials, and the second moving tilting mechanism 410 can move horizontally along the extension direction of the lifting frame 300. When the auxiliary construction device is in operation, the lifting frame 300 is perpendicular to the machine body 100 and is in an upright state. Therefore, the second moving tilting mechanism 410 can drive the support plate 420 to move up and down relative to the lifting frame 300, thereby completing the lifting movement of the materials supported on the support plate 420 during the upward movement.

[0043] Figure 1 When the auxiliary construction device is in the storage and transfer state, the support plate 420 is in a second storage state, tilted relative to the lifting frame 300. Compared to the working state, the support plate 420 has rotated more than 90 degrees relative to the second moving tilting mechanism 410, causing the end of the support plate 420 away from the second moving tilting mechanism 410 to abut against the lifting frame 300. It is understandable that the rotation of the support plate 420 relative to the second moving tilting mechanism 410 reduces the dimensions of the auxiliary construction device in both the length and height directions of the body 100 during the transition from the working state to the storage and transfer state. This allows the auxiliary construction device in the storage and transfer state to meet the requirements for use in a conventional construction elevator.

[0044] Optionally, refer to Figure 1 and Figure 2 The control cabinet 500 is fixed to one end of the machine body 100. A stop block 510 is provided on the side of the control cabinet 500. When the lifting frame 300 is in the first storage state, the second end of the lifting frame 300 abuts against the stop block 510.

[0045] It should be noted that the control cabinet 500 is installed at one end of the machine body 100, and the installation position of the control cabinet 500 and the fork assembly 400 are respectively located on both sides of the lifting frame 300. The second end of the lifting frame 300 is the end away from the first moving tilting mechanism. When the lifting frame 300 rotates from the first working state to the first retracted state relative to the first moving tilting mechanism, since the control cabinet 500 has a certain height, the second end of the lifting frame 300 will abut against the control cabinet 500. In this application, a stop 510 is provided on the side of the control cabinet 500, which serves as the abutment point for the second end of the lifting frame 300, thus protecting the control cabinet 500, preventing the lifting frame 300 from continuing to tilt towards the machine body 100, and also preventing damage to the outer shell of the control cabinet 500 due to inaccurate motion control during the rotation of the lifting frame 300 relative to the first moving tilting mechanism.

[0046] Optionally, the auxiliary construction device also includes a hydraulic motor, which drives the first moving tilting mechanism 200 to move in the horizontal direction of the machine body 100, and the hydraulic motor also drives the second moving tilting mechanism 410 to move up and down relative to the lifting frame 300.

[0047] Figure 2 , Figure 3 and Figure 4 The diagram shows the structure of the auxiliary construction device under different working conditions, for comparison. Figure 2 and Figure 3 ,from Figure 2 to Figure 3 During the process, the second moving tilting mechanism 410 moves upward relative to the lifting frame 300, thereby driving the support plate 420 connected to the second moving tilting structure to move upward together, realizing the lifting function of the material on the support plate 420. In this application, a hydraulic motor is set to drive the second moving tilting mechanism 410 to move up and down relative to the lifting frame 300, thereby providing a power source for lifting the material on the support plate 420 through the hydraulic motor.

[0048] contrast Figure 4 and Figure 3 ,from Figure 3 to Figure 4 During the process, the first moving tilting mechanism moves horizontally relative to the body 100 towards the control cabinet 500. It is understandable that when materials are loaded onto the support plate 420, it will cause an imbalance in the overall weight of the auxiliary construction device body 100, that is, the end with the loaded materials is heavier and the end with the control cabinet 500 is lighter, and the auxiliary construction device is at risk of tipping over.

[0049] In this embodiment, by driving the first moving tilting mechanism to move horizontally in the machine body 100, the load-bearing support plate 420 is moved horizontally in the machine body 100, thereby moving the heavier material from one end of the auxiliary construction device towards the center, adjusting the overall center of gravity of the auxiliary construction device after being loaded, and preventing the auxiliary construction device from tipping over and causing personnel and economic losses. Similarly, in this application, a hydraulic motor is used to drive the first moving tilting mechanism to move horizontally left and right relative to the machine body 100, thereby providing a power source for the left and right movement of the material on the support plate 420.

[0050] As an example, in this application, the rotation of the lifting frame 300 relative to the first moving tilting mechanism 200 is driven by the first moving tilting mechanism 200. That is, the first moving tilting mechanism 200 can drive the lifting frame 300 to switch between a first storage state and a first working state. In other words, the first moving tilting mechanism 200 provides power to drive the lifting frame 300 to switch between a position tilted relative to the body 100 and a position perpendicular to the body 100. Optionally, the first moving tilting mechanism 200 drives the rotation of the lifting frame 300 through a hydraulic motor.

[0051] As an example, in this application, the rotation of the support plate 420 relative to the second moving tilting mechanism 410 is driven by the second moving tilting mechanism 410. That is, the second moving tilting mechanism 410 can drive the support plate 420 to switch between a second storage state and a second working state. In other words, the second moving tilting mechanism 410 provides power to drive the support plate 420 to switch between a position tilted relative to the lifting frame 300 and a position perpendicular to the lifting frame 300. Optionally, the second moving tilting mechanism 410 drives the rotation of the lifting frame 300 via a hydraulic motor.

[0052] Understandably, in addition to driving the linear motion of the first and second moving tilting mechanisms 200 and 410, the hydraulic motor is also used to provide power to a transverse tilting mechanism and / or the second moving tilting mechanism 410, and to control the movement state of the lifting frame 300 and / or the support plate 420.

[0053] As an example, this application provides an auxiliary construction device that also includes a hydraulic control system 600 and an electrical control system 700, wherein the hydraulic control system 600 is used to control the operation of the hydraulic motor, and the electrical control system 700 is used to control the movement of at least one component of the first moving tilting mechanism 200, the lifting frame 300, and the fork assembly 400 in the auxiliary construction device.

[0054] Understandably, the electrical control system 700 is equipped with a PLC and related components. Through programming, it can control the movements of the entire auxiliary construction device, including controlling the horizontal movement of the first moving tilting mechanism 200 relative to the machine body 100, controlling the vertical movement of the second lateral moving mechanism relative to the lifting frame 300, controlling the rotation of the lifting frame 300 relative to the first moving tilting mechanism 200, and controlling the rotation of the support plate 420 relative to the second moving tilting mechanism 410. By operating the related components of the electrical control system 700, precise control of the movement of each component on the auxiliary construction device can be achieved.

[0055] refer to Figure 5During the operation of the auxiliary construction device, the lifting frame 300 is in a vertical state. The second moving tilting device drives the support plate 420 and the material loaded on the support plate 420 to gradually rise from the first end of the lifting frame 300 to the second end of the lifting frame 300, completing the lifting of the material. In one embodiment of this application, the lifting frame 300 is further designed to include a first frame 310 and a second frame 320. The second frame 320 is fitted inside the first frame 310 and can extend relative to the first frame 310. When the second moving tilting device moves to the second end of the lifting frame 300, the second frame 320 extends relative to the first frame 310, increasing the vertical height of the lifting frame 300. At this time, the second moving tilting device can further move upward relative to the second frame 320, thereby driving the support plate 420 and the material to continue to be lifted upward.

[0056] Understandably, by designing a second frame 320 that can extend from the first frame 310, the height at which the auxiliary construction device can lift materials is expanded, thereby making the auxiliary construction device applicable to more construction scenarios. At the same time, in the storage and transportation state, the second frame 320 is completely fitted inside the first frame 310, which will not lead to an increase in storage size and will not affect the auxiliary construction device from entering common construction elevators.

[0057] Optionally, the extension and retraction movements of the second frame 320 relative to the first frame 310 are also controlled by the electrical control system 700 and powered by a hydraulic motor.

[0058] As an example, refer to Figure 6 Both the hydraulic control system 600 and the electrical control system 700 are housed within the control cabinet 500. Optionally, a distance detection mechanism is also designed in the stop block 510 to monitor the distance between the lifting frame 300 and the stop block 510. When the detected distance between the lifting frame 300 and the stop block 510 exceeds a certain threshold, feedback is sent to the electrical control system 700 to reduce the rotation speed of the lifting frame 300, further protecting the control cabinet 500 and the stop block 510.

[0059] As an example, the auxiliary construction device also includes a drive unit 800 and a battery box 900. The drive unit 800 includes a steering linkage 810, a steering shaft 820, a wheel frame 830, and two drive wheels 840. One end of the steering shaft 820 is fixed to the wheel frame 830, and the other end is fixed to the machine body 100. The drive wheels 840 are installed inside the wheel frame 830. Each end of the steering linkage 810 is connected to a wheel frame 830, so that the two drive wheels 840 move synchronously.

[0060] Figure 7A schematic diagram of the drive unit 800 is shown. It is understood that the drive unit 800 further includes a steering cylinder 860, which drives the steering linkage 810 to move, providing power for the steering action of the auxiliary construction device. When the auxiliary construction device performs a steering movement, the steering cylinder 860 drives the steering linkage 810 to move, which in turn drives the left and right wheel carriers 830 to move, thereby causing the left and right drive wheels 840 to rotate synchronously. It is understood that one end of the steering shaft 820 is fixed to the wheel carrier 830, and the other end is fixed to the machine body 100. The wheel carrier 830 and the drive wheels 840 rotate about the steering shaft 820 as the center.

[0061] Optionally, the auxiliary construction device also includes a motor 870, which drives the drive wheel 840 to rotate, providing power for the movement of the auxiliary construction device. It is understood that the battery box 900 contains a battery and a charger. Optionally, the auxiliary construction device also includes a brake wheel 850, which provides braking force for the auxiliary construction device.

[0062] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
