Description

Technical Field

[0001] This utility model relates to the field of concrete construction tools, and in particular to a concrete construction formwork support for a high-speed ring road of an automobile proving ground. Background Technology

[0002] An automotive proving ground is an essential facility for testing the quality of automotive products. The high-speed ring track primarily tests the high-speed reliability and durability of vehicles, and is used for the research and development of vehicle powertrain systems, tires, and wheel systems. It can also provide durability tests for vehicle pollutant control devices and high-speed coasting tests, and is one of the core functional areas of the entire proving ground.

[0003] The pavement structure of the high-speed ring road at the automotive proving ground mainly consists of two types: asphalt pavement and concrete pavement. Due to cost considerations, concrete pavement structures are more commonly used. In existing technologies, the construction of concrete pavement for high-speed ring roads generally employs the skip-pour method. This method follows the principle of "block planning, intermittent construction, layered pouring, and overall molding," similar to a game of checkers, where sections are poured alternately. This echeloned operation allows for cyclical progress.

[0004] Therefore, due to the "block construction" characteristic of highway ring road concrete construction, the formwork used during concrete pouring is not continuous. Furthermore, the formwork needs to be removed, transported over long distances, and reinstalled before pouring the next section. Moreover, since steel formwork is frequently used in concrete construction, it is heavy and difficult to move, significantly impacting the efficiency of highway ring road concrete construction and related formwork usage.

[0005] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a concrete construction formwork support for a high-speed ring track of an automotive proving ground. Utility Model Content

[0006] The purpose of this utility model is to provide a formwork support for high-speed track concrete construction in automotive proving grounds, which can stably support the formwork and assist in the transportation, installation and fixing of the formwork to improve the overall efficiency of high-speed track concrete construction.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0043] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0044] See Figures 1 to 3 As shown;

[0045] This embodiment discloses a concrete construction formwork support for a high-speed ring road of an automotive proving ground, comprising:

[0046] The mobile flatbed truck 1 has a raised support plate 2 on its upper surface. This device can transport and transfer templates through the mobile flatbed truck 1 to cope with the construction method of skip-section construction. The raised support plate 2 is used to assemble related structures and raise them to a suitable height to better support, fix and transfer the templates.

[0047] The load-bearing upright plate 3 is vertically fixed to one side of the upper surface of the raised support plate 2. Two sets of notches 4 are symmetrically opened on the upper end face of the load-bearing upright plate 3. A horizontal shaft 5 is set in the notch 4. A rotating sleeve 6 is sleeved on the horizontal shaft 5. The rotating sleeve 6 rotates axially on the horizontal shaft 5.

[0048] The fixed plate 7 has two sets of tripods 8 vertically installed on one side. The two sets of tripods 8 are correspondingly installed with the two sets of rotating sleeves 6. One end of the tripod 8 is fixedly connected to the fixed plate 7, and the other end is fixedly connected to the outer side of the rotating sleeve 6. That is, the fixed plate 7 is connected to the rotating sleeve 6 through the support of the tripods 8. When the rotating sleeve 6 rotates, the fixed plate 7 is driven to rotate by the swing of the tripods 8.

[0049] The lifting plate 9 is fixedly connected to the steel formwork of the concrete construction on one side and abuts against the fixed plate 7 on the other side. The lifting plate 9 and the fixed plate 7 slide relative to each other.

[0050] The lifting adjustment mechanism is set between the fixed plate 7 and the lifting plate 9 to drive the lifting plate 9 to move up and down relative to the fixed plate 7. When the lifting plate 9 moves up and down, in order to support the stability of the lifting plate 9 and make the position between the lifting plate 9 and the fixed plate 7 relatively close to improve the structural stability, the lifting adjustment mechanism will cause the lifting plate 9 and the fixed plate 7 to slide relative to each other when driving the lifting plate 9 to move up and down.

[0051] The swing frame structure has one end connected to the outer surface of the rotating sleeve 6 and the other end extending in the opposite direction to the tripod 8. When the swing frame structure swings, it drives the rotating sleeve 6 to rotate, thereby driving the tripod 8 to swing. When the swing frame structure is kept in a horizontal state, the fixed plate 7 supported by the tripod 8, the lifting plate 9, and the steel formwork for concrete construction are kept in a vertical state. This state is the working state of the steel formwork, that is, when installing the formwork, it needs to be kept in a vertical and upright state for construction.

[0052] The horizontal angle fixing mechanism, located on the side opposite to the load-bearing upright plate 3 on the upper surface of the raised support plate 2, is used to keep the swing frame structure in a horizontal state. That is, after the template is moved to a suitable position, the horizontal angle fixing mechanism ultimately fixes the template in its working state, improving the template installation efficiency. It is essential to ensure the horizontal state of the mobile flatbed trolley 1 to guarantee that the template is supported in a vertical, upright position.

[0053] Furthermore, the transverse length of the steel formwork for concrete construction fixed on the lifting plate 9 is set parallel to the moving direction of the mobile flatbed truck 1. This prevents the steel formwork from moving along a direction perpendicular to the concrete due to the rolling of the wheels of the mobile flatbed truck 1, thus ensuring the stability of the formwork. Setting the moving direction of the mobile flatbed truck 1 based on the transverse length of the steel formwork means that the length direction is the continuous arrangement direction of the formwork, and the positional constraints between the formwork can be used to make the formwork fixed stably.

[0054] Furthermore, the lifting and adjusting mechanism includes:

[0055] The first vertical guide hole 10 is two sets symmetrically opened at both ends of the fixed plate 7;

[0056] The guide slider 11 consists of two sets symmetrically connected to the two ends of the lifting plate 9 and corresponding to the two sets of first vertical guide holes 10. The guide slider 11 passes through the first vertical guide hole 10 and slides inside the first vertical guide hole 10. One end of the guide slider 11 that passes through the first vertical guide hole 10 is connected to a limit block 12, and the limit block 12 slides on the fixed plate 7.

[0057] The second vertical guide hole 13 is opened on the fixing plate 7 and is located between the two sets of first vertical guide holes 10;

[0058] Connecting block 14, one end of which is connected to the center of lifting plate 9, and the other end passes through the second vertical guide hole 13 and slides within the second vertical guide hole 13. A vertically positioned nut pair 15 is connected to one end of connecting block 14 that passes through the second vertical guide hole 13; and

[0059] The first threaded rod 16 is vertically mounted on the side surface of the fixed plate 7 facing away from the lifting plate 9. The two ends of the first threaded rod 16 are connected to the fixed plate 7 by bearings, allowing the first threaded rod 16 to rotate axially. The first threaded rod 16 is coaxially inserted into the nut pair 15 and threadedly engaged with the nut pair 15. The upper end of the first threaded rod 16 is provided with a first rotating handle 17.

[0060] Specifically, when adjusting the height of the template, the first threaded rod 16 is driven to rotate by the first rotary handle 17, causing the threaded rod 16 to engage with the nut pair 15. This allows the nut pair 15 to move the lifting plate 9 up and down via the connecting block 14, thereby moving the template up and down. This facilitates the movement of the template during installation and fixation after the position is determined. The guide slider 11, passing through the first vertical guide hole 10, is limited by the limiting block 12, ensuring a relatively tight position between the lifting plate 9 and the fixed plate 7, thus improving structural stability. Therefore, when the lifting adjustment mechanism drives the lifting plate 9 to move up and down, the lifting plate 9 and the fixed plate 7 will slide relative to each other. At this time, the guide slider 11 slides within the first vertical guide hole 10, guiding the movement of the lifting plate 9 and making the template's height adjustment more stable.

[0061] Furthermore, the swing frame structure includes:

[0062] Connecting rods 18 consist of two identical sets, each corresponding to one of the two sets of rotating sleeves 6. One end of each set of connecting rods 18 is fixedly connected to the outer surface of the corresponding rotating sleeve 6, and the other end is fitted with a crossbar 19. The crossbar 19 connects the two sets of connecting rods 18 to form a frame, allowing force to be applied to the crossbar 19, causing the two sets of connecting rods 18 to swing synchronously.

[0063] The extension rod 20 is vertically connected to the center of the crossbar 19 on the side opposite to the connecting rod 18. By controlling the lifting and swinging of the extension rod 20 at the far end, the crossbar 19 drives the two sets of connecting rods 18 to swing synchronously, thereby driving the rotating sleeve 6 to rotate. The length settings of the connecting rod 18 and the extension rod 20 utilize the lever principle to achieve the effect of saving effort during adjustment.

[0064] Furthermore, the horizontal angle fixing mechanism includes:

[0065] Counterweight 21 is positioned above the lifting support plate 2;

[0066] Loading box 22, used to load counterweight 21, with casters 23 on the lower surface of counterweight 21 to facilitate movement of loading box 22; and

[0067] The limiting seat 24 is fixedly connected to the outer surface of the loading box 22, and the limiting seat 24 is provided with a limiting groove 25 for inserting the extension rod 20.

[0068] When the extension rod 20 is inserted into the limiting groove 25, the swing frame structure remains in a horizontal state. That is, by setting the height of the limiting groove 25, the swing frame structure is kept in a horizontal state when the extension rod 20 is inserted into the limiting groove 25.

[0069] The counterweight 21 is positioned opposite to the side where the template is located, serving a balancing function to effectively support the stability of the template. At the same time, the weight of the counterweight 21 itself is used to insert the extension rod 20 into the limiting groove 25 to more stably fix the extension rod 20, so that it can be stably kept in a horizontal state, thereby stably fixing the template.

[0070] Furthermore, the horizontal angle fixing mechanism also includes:

[0071] Vertical support plate 26, which is vertically fixed to the upper surface of the raised support plate 2 on the side opposite to the load-bearing upright plate 3;

[0072] A horizontal support plate 27 is horizontally connected to the top of a vertical support plate 26. A second threaded rod 28 is provided on the horizontal support plate 27, which vertically passes through the horizontal support plate 27 and is threadedly engaged with it. The lower end of the second threaded rod 28 is provided with an abutment plate 29 that abuts against the upper surface of the extension rod 20. A second rotating handle 30 is provided at the upper end of the second threaded rod 28.

[0073] The third threaded rod 31 is horizontally inserted through the vertical support plate 26 and threadedly engaged with the vertical support plate 26. One end of the third threaded rod 31 is rotatably connected to the outer surface of the loading box 22 opposite to the side of the limiting seat 24 via a bearing, and the other end is provided with a third rotary handle 32.

[0074] Specifically, supported by the vertical support plate 26 and the horizontal support plate 27, the second threaded rod 28 is manually rotated axially via the second rotary handle 30 through the threaded engagement between it and the horizontal support plate 27. This allows for axial movement of the second threaded rod 28 within the threaded engagement with the horizontal support plate 27. Consequently, the abutment plate 29 abuts against the extension rod 20, pushing the end of the extension rod 20 to swing. The downward swing of the upper end of the extension rod 20 causes the template to swing upward, facilitating the movement and transfer of the template. The template height can also be adjusted via a lifting adjustment mechanism to further facilitate movement and transfer, and to minimize the risk of collision with the ground. The lower end of the second threaded rod 28 and the abutment plate 29 are connected by a hinge, allowing the abutment plate 29 to rotate relative to the second threaded rod 28, thus enabling the abutment plate 29 to better conform to the extension rod 20 for pushing. During the use of the template, if it is necessary to keep the extension rod 20 in a horizontal state, the height of the abutment plate 29 is adjusted so that the extension rod 20 is kept in a horizontal state under the restriction of the abutment plate 29. At this time, the third threaded rod 31 is driven to rotate by the third rotary handle 32. The threaded engagement between the third threaded rod 31 and the vertical support plate 26 causes the third threaded rod 31 to move axially and drive the loading box 22 and its loaded counterweight 21 to move, and the limiting seat 24 moves accordingly until the extension rod 20 is inserted into the limiting groove 25 to fix the extension rod 20 more stably, so that it can be stably kept in a horizontal state, thereby stably fixing the template.

[0075] The above technical solution provides a concrete construction formwork support for a high-speed ring road of an automotive proving ground, which has the following beneficial effects:

[0076] This invention enables the use of skip-pour concrete construction in high-speed test tracks for automobile proving grounds. It facilitates the transportation and transfer of formwork used in concrete construction, provides stable support for the formwork, and allows for adjustment of the support height during formwork installation to better assist in the installation process. It is more suitable for formwork support in skip-pour concrete construction, thereby improving construction efficiency.

[0077] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
