Technical Field

[0001] This application relates to the field of construction load-bearing technology, specifically to a construction load-bearing device. Background Technology

[0002] Construction support platforms are commonly used on-site equipment in the engineering construction field. To facilitate the adjustment of the platform's position on site, some construction support platforms are equipped with casters at their bottom. For example, existing technology has disclosed a civil engineering safety construction frame, which includes a base with casters, a lifting mechanism, a support frame, and an output device mounted on the base. The support frame is used to support and protect construction personnel, and the output device outputs power to move the support frame to the target construction height through the lifting mechanism for construction operations.

[0003] In existing construction support platforms, on uneven surfaces or slopes, when the support frame on the support platform rises to a certain height and operators perform construction operations at height, the center of gravity of the support platform increases and the traction of the moving wheels is insufficient, which can easily cause the support platform to become unstable and affect construction safety.

[0005] The embodiments in this specification provide the following technical solutions: A construction support device includes: a base; a plurality of hydraulic support components distributed around the base, specifically including: a first hydraulic chamber extending longitudinally and fixed to the base; a first piston rod, one end of which is hydraulically driven and movable within the first hydraulic chamber; a support plate connected to the other end of the first piston rod and positioned below the base; and a hydraulic drive component positioned on the base, adapted to provide hydraulic pressure to the plurality of hydraulic support components to drive the first piston rod to move up and down, and correspondingly drive the support plate to press downward against and support the ground or detach from the ground.

[0006] To optimize the above solution, the following technical measures were also adopted: In one embodiment, the hydraulic drive component includes: a plurality of hydraulic conversion units, each corresponding to one of the plurality of hydraulic support components; and a drive unit, which is connected to the plurality of hydraulic conversion units to convert the mechanical force output by the drive unit into the hydraulic pressure required by the hydraulic support components.

[0007] In one embodiment, the hydraulic conversion unit includes: a second hydraulic chamber fixed on the base and arranged side-by-side with the first hydraulic chamber; a second piston rod, one end of which is mechanically driven to move up and down within the second hydraulic chamber; a connecting pipe connecting the second hydraulic chamber and the first hydraulic chamber and configured to distribute hydraulic fluid between the two to drive the first piston rod toward a side opposite to the direction of movement of the second piston rod; wherein the drive unit is tractively connected to the other end of the second piston rod to provide the second piston rod with the mechanical force to move it up and down.

[0008] As one embodiment, it also includes a linkage component, which is fixedly connected to the second piston rod of the plurality of hydraulic conversion units, and the linkage component is drive-connected to the drive unit.

[0009] In one embodiment, the drive unit includes a drive motor and a vertical first movable screw fixedly connected to the output shaft of the drive motor, and the linkage component is provided with a first nut seat adapted to the first movable screw.

[0010] As one embodiment, it also includes a lifting platform, which is connected to the drive motor, and the drive motor is configured to drive the first piston rod and the lifting platform to move in opposite directions.

[0011] As one embodiment, it also includes a vertical second movable screw fixedly connected to the output shaft of the drive motor, and a second nut seat adapted to the second movable screw is provided on the lifting platform.

[0012] In one embodiment, at least one guide tube extending vertically is formed on the base, and a guide post adapted to the guide tube is provided on the lifting platform. A positioning structure for limiting the height position of the lifting platform is provided between the guide tube and the guide post.

[0013] In one embodiment, the positioning structure includes a plurality of first positioning holes arranged vertically on the guide post, at least one second positioning hole formed on the guide tube, and a positioning element penetrating the corresponding first and second positioning holes.

[0014] In one embodiment, the support plate is movably or fixedly connected to the first piston rod, and the bottom of the support plate has serrated parts for contacting the ground to increase grip.

[0015] Compared with the prior art, the beneficial effects that at least one technical solution adopted in the embodiments of this specification can achieve include at least: Firstly, when the construction support device in this application supports the operator to carry out construction operations, it can provide hydraulic pressure to multiple hydraulic support components on the base through hydraulic drive components, so as to drive the first piston rod in the first hydraulic chamber of multiple hydraulic support components to move downward, so that the support plate presses against the ground, thereby enhancing the grip of the support device, improving the stability of the device, and ensuring construction safety.

[0016] Furthermore, the hydraulic drive component adopts a hydraulic conversion unit consisting of a second hydraulic chamber arranged side by side with the first hydraulic chamber and connected by a connecting pipe, and a second piston rod disposed in the second hydraulic chamber. This unit converts the mechanical force output by the drive unit into the hydraulic pressure required by the hydraulic support component. The arrangement of the hydraulic chambers determines the stroke of the piston rod. The side-by-side arrangement of the first and second hydraulic chambers means that the stroke range of the first and second piston rods is roughly the same. This can greatly reduce the space occupied by the hydraulic drive component in the vertical direction, which is conducive to the compactness and miniaturization of the device.

[0024] This specification provides an embodiment of a construction load-bearing device for civil engineering, such as... Figures 1 to 5 As shown, the present invention aims to solve the problem of unstable ground grip of the support mechanism of the existing construction support platform, which easily causes the support platform to sway or even tilt during construction, affecting construction safety. It can not only greatly increase the ground grip performance of the support mechanism of the support platform, improve support stability and ensure construction safety, but also further expand the application scenarios of the support device and increase the adaptability and flexibility of the support device.

[0025] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0026] Example 1 like Figure 1 , Figure 2 as well as Figure 5 As shown in the figure, this specification provides a construction support device, including a base 1, multiple hydraulic support components, and a hydraulic drive component. In this embodiment, the base 1 is a rectangular plate, and the multiple hydraulic support components are distributed around the base 1. Specifically, in this embodiment, there are four hydraulic support components respectively arranged at the four corners of the base 1. Figure 5 As shown, in other embodiments, two, three, or five hydraulic support components can be configured according to the shape of the base 1, the requirements for support stability, and the equipment cost requirements, which will not be elaborated here. In this embodiment, the hydraulic support components specifically include a first hydraulic chamber 21, a first piston rod, and a support plate 24. The first hydraulic chamber 21 is fixed to the base 1 along the longitudinal direction. One end of the first piston rod is driven by hydraulic pressure and is movable up and down in the first hydraulic chamber 21. The other end of the first piston rod is connected to the support plate 24 located below the base 1. Specifically, the first piston rod includes a first piston 22 and a support rod 23 fixedly connected to the first piston 22. The first piston 22 is slidably engaged with the first hydraulic chamber. The first hydraulic chamber 21 has a first oil port and a first movable hole respectively located on both sides of the first piston 22. The support rod 23 is slidably sealed with the first movable hole. The hydraulic drive component is positioned on the base 1 and is adapted to provide hydraulic pressure to the plurality of hydraulic support components to drive the first piston rod to move up and down, and correspondingly drive the support plate 24 to press down against and support the ground or detach from the ground.

[0027] In one embodiment, when the above-mentioned construction support device is used, the entire support device is first moved to the target construction site. Then, construction personnel and / or equipment are loaded onto the support platform on the base 1. Simultaneously, the hydraulic drive components are operated to provide hydraulic pressure to multiple hydraulic support components. Driven by hydraulic force, the first piston rod moves from its retracted position within the first hydraulic chamber 21 to its supporting position, which presses the support plate 24 against the ground. Figure 2 As shown, the support plates 24 of each hydraulic support component are pressed against the ground, thereby enhancing the grip of the bearing device, improving the stability of the device, and ensuring construction safety. After construction is completed, the hydraulic drive component is operated again to provide hydraulic pressure in the opposite direction to the first piston rod, driving it from the supported position back to the retracted position located in the first hydraulic chamber 21, completing the reset of the first piston rod.

[0028] Preferably, the lower part of the base 1 has a plurality of upwardly recessed storage recesses, which correspond one-to-one with a plurality of support plates 24. In the retracted position, the support plates 24 are stored in the storage recesses.

[0029] In this embodiment, the hydraulic drive component specifically includes multiple hydraulic conversion units and one drive unit. Each of the multiple hydraulic conversion units corresponds one-to-one with one of the multiple hydraulic support components. The drive unit is connected to the multiple hydraulic conversion units to convert the mechanical force output by the drive unit into the hydraulic pressure required by the hydraulic support components. In some embodiments, the hydraulic conversion unit can be composed of hydraulic lines connecting a hydraulic tank, a hydraulic pump, and a flow distribution valve. The hydraulic pump can be driven by the drive unit to control the inflow and outflow of oil in the first hydraulic chamber 21, thereby achieving the technical purpose of controlling the movement of the first piston rod. The flow distribution valve ensures that the flow rate in the hydraulic lines connected to each hydraulic chamber is approximately balanced. This structure and concept of the hydraulic conversion unit are commonly used in the prior art and will not be elaborated upon here. Because a hydraulic tank and a hydraulic pump are required, the structural and operational costs of this hydraulic conversion unit are relatively high, and it occupies a large space.

[0030] In this embodiment, the hydraulic conversion unit can adopt the same structure as the hydraulic support component, specifically including a second hydraulic chamber 31, a second piston rod, and a connecting pipe 30. The second hydraulic chamber 31 is fixed on the base 1 and arranged side by side with the first hydraulic chamber 21. One end of the second piston rod is mechanically driven to move up and down in the second hydraulic chamber 31. The connecting pipe 30 connects the second hydraulic chamber 31 and the first hydraulic chamber 21 and is configured to distribute hydraulic fluid between the two to drive the first piston rod to move toward a side opposite to the direction of movement of the second piston rod. The drive unit is driven to the other end of the second piston rod to provide the mechanical force for the second piston rod to move up and down.

[0031] Here, on the one hand, the hydraulic drive component adopts a hydraulic conversion unit consisting of a second hydraulic chamber 31 arranged side-by-side with the first hydraulic chamber 21 and connected by a connecting pipe 30, and a second piston rod disposed within the second hydraulic chamber 31. This unit converts the mechanical force output by the drive unit into the hydraulic pressure required by the hydraulic support component. The arrangement of the hydraulic chambers determines the stroke of the piston rod. The side-by-side arrangement of the first hydraulic chamber 21 and the second hydraulic chamber 31 means that the stroke ranges of the first and second piston rods are roughly the same. This significantly reduces the space occupied by the hydraulic drive component vertically, facilitating the compactness and miniaturization of the device. On the other hand, the hydraulic conversion unit and the hydraulic support component can adopt the same structure, which increases the interchangeability and maintainability of the components of the load-bearing device.

[0032] like Figures 1 to 4 As shown, the supporting device further includes a linkage component 37, which is fixedly connected to the second piston rod of the plurality of hydraulic conversion units and is also drively connected to the drive unit. In one embodiment, the linkage component 37 is a truss-shaped, plate-shaped, or other rigid structure, and the top end of the second piston rod is fixedly connected to the linkage component 37. Specifically, the second piston rod includes a second piston 32 and a vertical drive rod 33 fixedly connected to the second piston 32. The second piston 32 is slidably engaged with the second hydraulic chamber 31, which has a second oil port and a second movable hole located above the second piston 32. The drive rod 33 is slidably sealed with the second movable hole. A connecting pipe 30 is connected between the first oil port and the second oil port.

[0033] In this embodiment, the drive unit includes a drive motor 34 and a vertical first moving screw 35 fixedly connected to the output shaft of the drive motor 34. The linkage component 37 is provided with a first nut seat 36 adapted to the first moving screw 35. In one embodiment, the bearing device operates as follows: when it is necessary to stably support the bearing device on the ground, the drive motor 34 is started to rotate forward, the first moving screw 35 rotates and drives the first nut seat 36 to move upward, the linkage component 37 follows the first nut seat 36 to move upward, thereby driving the second piston rod to move upward. The oil in the second hydraulic chamber 31 enters the first hydraulic chamber 21 through the second oil port, the connecting pipe 30 and the first oil port in sequence, driving the first piston rod to move downward, so that the support plate 24 is stably pressed against and supported on the ground, increasing the grip of the bearing device, thereby making the bearing device stably supported on the ground, while the personnel and / or equipment on the bearing device carry out construction work. After construction is completed, the drive motor 34 is started to rotate in the opposite direction. The first moving screw 35 rotates and drives the first nut seat 36 to move downward. The linkage component 37 drives the second piston rod to move downward. The oil flows back into the second hydraulic chamber 31, driving the first piston rod to move upward and reset.

[0034] Example 2 like Figure 3 and Figure 4As shown, this embodiment is essentially the same as Embodiment 1, except that in this embodiment, the supporting device further includes a lifting platform 4, which is connected to the drive motor 34. The drive motor 34 is configured to drive the first piston rod and the lifting platform 4 in opposite directions. That is, the rising process of the lifting platform 4 and the downward force application of the support plate 24 occur simultaneously, which can improve construction efficiency. At the same time, when the lifting platform 4 moves upward, the center of gravity increases, making the supporting device more prone to swaying during construction. Therefore, during this process, the first piston rod moves downward to press the support plate 24 against the ground, increasing the grip and preventing the supporting device from swaying. In another embodiment, after the support plate 24 presses against the ground, the hydraulic pressure is further increased to increase the pressure between the support plate 24 and the ground, thereby increasing the friction between them and making the supporting device more stable on the construction ground. In other words, when the lifting platform 4 rises to its highest position, the first piston rod should at least move downward to a position where the support plate 24 contacts the ground.

[0035] Specifically, such as Figure 4 As shown, the supporting device further includes a vertical second movable screw 42 fixedly connected to the output shaft of the drive motor 34, and a second nut seat 43 adapted to the second movable screw 42 is provided on the lifting platform 4. In one embodiment, a rotating shaft 41 is fixedly provided at the upper end of the first movable screw 35, and the upper end of the rotating shaft 41 is connected to the second movable screw 42, for example, through a coupling. The upper end of the second movable screw 42 is positioned on the base 1 by a bearing. Thus, while the drive motor 34 drives the first movable screw 35 to rotate, the second movable screw 42 also rotates synchronously.

[0036] Here, the pitch of the second moving screw 42 is related to the lifting stroke and amplitude of the lifting platform 4, but not to the pitch of the first moving screw 35. The rotation directions of the first moving screw 35 and the second moving screw 42 can be the same or different, depending on the construction conditions and site requirements. The first moving screw 35 and the second moving screw 42 are driven by the same drive motor 34, which further reduces the structural and operating costs of the device.

[0037] To improve the stability of the lifting platform 4 during the lifting process, at least one guide tube 51 extending vertically is formed on the base 1. In this embodiment, a vertical guide tube 51 is fixedly installed on the upper part of each first hydraulic chamber 21. A guide post 53 adapted to the guide tube 51 is provided on the lifting platform 4. A guide seat 52 is also provided at the bottom of the guide post 53. The bottom of the guide tube 51 has a limiting part. When the lifting platform 4 is in the initial position, the guide seat 52 presses down against the limiting part. A positioning structure for limiting the height position of the lifting platform 4 is provided between the guide tube 51 and the guide post 53.

[0038] Specifically, such as Figure 3 and Figure 4 As shown, the positioning structure includes a plurality of first positioning holes 531 arranged at equal intervals along the vertical direction on the guide post 53, at least one second positioning hole formed on the guide tube 51, and positioning elements penetrating the corresponding first positioning holes 531 and second positioning holes. In this embodiment, a second positioning hole is provided on the guide tube 51, and the positioning element is a positioning bolt 532 penetrating the corresponding first positioning hole 531 and second positioning hole. When the lifting platform 4 rises from the initial position to the target height, one of the first positioning holes 531 on the guide tube 51 aligns with the second positioning hole. At this time, the operator can lock the height position of the lifting platform 4 by screwing the positioning bolt 532 into the first positioning hole 531 and the second positioning hole. The positioning structure further increases the stability of the lifting platform 4.

[0039] In this embodiment, the support plate 24 is movably or fixedly connected to the first piston rod. In one implementation, the support plate 24 is movably connected to the first piston rod via a hinge. This allows the support plate 24 to more freely and flexibly rest against the support surface, enabling the load-bearing device to be stably reinforced on the support surface even in special situations, such as uneven ground and / or slopes, increasing the stability of the load-bearing device and ensuring construction safety. This further expands the applicable construction sites or scenarios for the load-bearing device.

[0040] In addition, in this embodiment, the bottom of the support plate 24 has serrated parts for contacting the ground to increase grip.

[0041] In addition, in this embodiment, the bottom of the base 1 has a caster wheel 6 for moving and supporting the base 1, and the caster wheel 6 is preferably a caster wheel 6 with a self-locking function.

[0042] In summary, in the above embodiments, when the construction bearing device carries operators and / or equipment for construction operations, it can provide hydraulic pressure to multiple hydraulic support components on the base 1 through hydraulic drive components, so as to drive the first piston rod in the first hydraulic chamber 21 of multiple hydraulic support components to move downward, so that the support plate 24 presses against the ground, thereby enhancing the grip of the bearing device, improving the stability of the device, and ensuring construction safety.

In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
