Description

Technical Field

[0001] This utility model belongs to the field of building production technology, and specifically relates to a support device for manufacturing concrete structural components with stress monitoring. Background Technology

[0002] Concrete structural components refer to building structural elements made of concrete. Concrete is a hard material made of cement, aggregate, sand and water, used in building and foundation engineering. During the manufacturing process of concrete structural components, they need to be supported to ensure stability. Traditional support devices mostly adopt fixed structures, whose height and support force are difficult to adjust, and cannot meet the manufacturing needs of concrete structural components of different sizes and shapes. In recent years, telescopic support devices have been increasingly used. These devices achieve height adjustment by driving a sliding column with a hydraulic cylinder, offering advantages such as high flexibility and ease of operation. However, during the support process, operators must constantly monitor the support effect to prevent the device from collapsing due to excessive load. The telescopic section of the support device is particularly problematic, as it often extends into another section, making it thinner than the other section. This makes the telescopic section more prone to reaching its support limit during support. Therefore, monitoring for excessive deformation of the telescopic section is crucial to assess the support effect. However, this operator-managed monitoring method is extremely time-consuming and inefficient, and prone to oversights, leading to safety issues. Consequently, existing technologies suffer from the problem of not being able to monitor the support capacity of the telescopic section of the support device in real time. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a concrete structural component manufacturing support device with stress monitoring, which solves the problem that existing technologies make it inconvenient to monitor the support capacity of the expansion joint of the support device in real time.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] Manufacturing support devices for concrete structural components with stress monitoring, including fixed columns;

[0006] The fixed column is placed vertically, and a sliding groove with a coaxial orientation is opened inside the fixed column, which runs through the upper end of the fixed column;

[0007] A sliding column is slidably connected inside the chute, and the upper end of the sliding column extends out of the chute and is fixedly connected to a top pad;

[0008] A lifting part is installed inside the slide groove to connect the sliding column. The lifting part is used to drive the sliding column to move along the slide groove.

[0009] The sliding sleeve on the sliding column is equipped with a protective sleeve, which is located between the fixed column and the top pad.

[0010] A drive unit is provided at the lower end of the top pad, and a monitoring component is connected to the drive unit. The monitoring component is connected to the protective sleeve. The drive unit is used to drive the monitoring component to move between the top pad and the fixed column along the axis of the sliding column.

[0011] The principle and effect of the above technical solution are as follows:

[0012] In use, the fixed column is placed vertically, and the sliding column is raised and lowered by the lifting unit, so that the top pad supports the lower end of the concrete structure component. It can be used to support concrete structure components at various heights during manufacturing. The driving unit drives the monitoring component to move along the axis of the sliding column, so that the monitoring component moves back and forth between the top pad and the fixed column. The detection component monitors the stress of the sliding column, so as to realize real-time monitoring of the support capacity of the part of the sliding column that extends out of the fixed column. When the monitoring detects that any part of the sliding column that extends out of the fixed column reaches the support limit, the monitoring component moves the protective sleeve to the part that has reached the support limit and then stops moving. The protective sleeve temporarily reinforces the part that has reached the support limit.

[0013] The monitoring component includes a slider, which is fixedly connected to a protective sleeve. A pair of detectors are fixed on the slider and placed symmetrically up and down. Both detectors face the sliding column horizontally and are located at both ends of the protective sleeve along the axis of the sliding column.

[0015] The drive unit includes a screw rotatably connected to the lower end of the top pad, the screw and the sliding column are placed coaxially, the screw passes through the slider and is threadedly connected to the slider, the lower end of the screw is rotatably connected to a sliding plate, one side of the sliding plate is provided with a groove adapted to the protrusion, the groove is slidably engaged with any protrusion, and a rotary motor is fixedly installed at the lower end of the sliding plate, the output end of the rotary motor is connected to the screw.

[0016] A bottom pad is fixed at the lower end of the fixed column, and the bottom area of ​​the bottom pad is larger than the bottom area of ​​the fixed column.

[0017] The bottom pad is made of rigid material, while the top pad is made of elastic material.

[0018] The lifting unit includes a hydraulic cylinder that is vertically fixed to the bottom surface of the inner side of the slide groove, and the output end of the hydraulic cylinder is fixedly connected to the bottom of the sliding column.

[0019] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0022] The beneficial effects of this utility model are:

[0023] 1. The lifting unit drives the sliding column to adjust its height, so that the top pad supports the lower end of the concrete structure component. It can be used to support the concrete structure component at various heights during manufacturing. The driving unit drives the monitoring component to move along the axis of the sliding column, so that the monitoring component moves back and forth between the top pad and the fixed column. The detection component monitors the stress of the sliding column, so as to realize the real-time monitoring of the support capacity of the part of the sliding column that extends out of the fixed column.

[0024] When the monitoring component detects that any part of the sliding column extending out of the fixed column reaches the support limit, the monitoring component moves the protective sleeve to the part that has reached the support limit and then stops moving, and temporarily reinforces the part that has reached the support limit through the protective sleeve.

Specifically, the support device is constructed as a split structure, comprising a fixed column 100, a sliding column 200, a top pad 300, a lifting section 400, a protective sleeve 500, a drive unit, and a monitoring unit. In use, the fixed column 100 is placed vertically, and the sliding column 200 is adjusted by the lifting section 400, so that the top pad 300 supports the lower end of the concrete structural component. This device is suitable for supporting concrete structural components at various heights during manufacturing. The drive unit drives the monitoring component to move along the axis of the sliding column 200, allowing the monitoring component to move back and forth between the top pad 300 and the fixed column 100. The detection component monitors the stress of the sliding column 200, enabling real-time monitoring of the supporting capacity of the portion of the sliding column 200 extending beyond the fixed column 100.

[0033] When the monitoring component detects that the sliding column 200 extends out of the fixed column 100 to the support limit, the monitoring component moves the protective sleeve 500 to the position that has reached the support limit and then stops moving, and the protective sleeve 500 temporarily reinforces the position that has reached the support limit.

[0034] Please refer to Figures 1 to 3 A support device for manufacturing concrete structural components with stress monitoring, including a fixed column 100;

[0035] The fixed column 100 is placed vertically, and a sliding groove 101 is provided inside the fixed column 100, which is placed on the same axis and passes through the upper end of the fixed column 100.

[0036] A sliding column 200 is slidably connected inside the slide groove 101. The upper end of the sliding column 200 extends out of the slide groove 101 and is fixedly connected to a top pad 300.

[0037] A lifting part 400 connected to the sliding column 200 is installed inside the slide groove 101. The lifting part 400 is used to drive the sliding column 200 to move along the slide groove 101.

[0038] A protective sleeve 500 is provided on the sliding column 200, and the protective sleeve 500 is located between the fixed column 100 and the top pad 300;

[0039] A drive unit is provided at the lower end of the top pad 300. A monitoring component is connected to the drive unit. The monitoring component is connected to the protective sleeve 500. The drive unit is used to drive the monitoring component to move between the top pad 300 and the fixed column 100 along the axis of the sliding column 200.

[0040] In use, the fixed column 100 is placed vertically, and the sliding column 200 is adjusted by the lifting part 400 so that the top pad 300 is supported at the lower end of the concrete structure component. It can be used to support concrete structure components at various heights during manufacturing. The monitoring component is driven by the driving unit to move along the axis of the sliding column 200, so that the monitoring component moves back and forth between the top pad 300 and the fixed column 100. The stress of the sliding column 200 is monitored by the detection component, so as to realize the real-time monitoring of the supporting capacity of the part of the sliding column 200 extending out of the fixed column 100.

[0041] When the monitoring component detects that the sliding column 200 extends out of the fixed column 100 to the support limit, the monitoring component moves the protective sleeve 500 to the position that has reached the support limit and then stops moving, and the protective sleeve 500 temporarily reinforces the position that has reached the support limit.

[0042] The monitoring component includes a slider 701, which is fixedly connected to the protective sleeve 500. A pair of detectors 702 are fixed on the slider 701 and are placed symmetrically up and down. Both detectors 702 are horizontally facing the sliding column 200, and the two detectors 702 are located at both ends of the protective sleeve 500 along the axis of the sliding column 200.

[0043] By setting up two detectors 702, the sliding column 200 at both ends of the protective sleeve 500 can be monitored simultaneously during movement, avoiding the problem that a single detector 702 can only monitor the sliding column 200 at one end of the protective sleeve 500, thus improving the accuracy of monitoring.

[0044] Preferably, detector 702 can be an X-ray detector 702;

[0045] Preferably, the monitoring component of this application also includes an early warning device disposed on the slider 701. When the slider 200 is detected to have reached its support limit at any part, the early warning device will issue an early warning signal to remind the staff.

[0046] Multiple evenly distributed protrusions 102 are fixed on the outer peripheral wall of the fixed column 100. All protrusions 102 are placed in the same axis as the fixed column 100. The protrusions 102 improve the strength of the fixed column 100 and enhance the safety performance during the support process.

[0047] The drive unit includes a screw 601 rotatably connected to the lower end of the top pad 300. The screw 601 and the sliding column 200 are placed coaxially. The screw 601 passes through the slider 701 and is threadedly connected to the slider 701. A sliding plate 602 is rotatably connected to the lower end of the screw 601. A groove adapted to the protrusion 102 is provided on one side of the sliding plate 602. The groove is slidably engaged with any of the protrusions 102. A rotary motor 603 is fixedly installed at the lower end of the sliding plate 602. The output end of the rotary motor 603 is connected to the screw 601. By turning on the rotary motor 603, the rotary motor 603 drives the screw 601 to rotate. Due to the orientation limit of the slider 701 by the protective sleeve 500 and the sliding column 200, the slider 701 rotates with the screw 601 and undergoes threaded transmission. By changing the rotation direction of the output end of the rotary motor 603, the lifting and lowering direction of the slider 701 is controlled, thereby realizing the reciprocating movement of the drive monitoring component between the top pad 300 and the fixed column 100.

[0048] A bottom pad 800 is fixed at the lower end of the fixed column 100. The bottom area of ​​the bottom pad 800 is larger than the bottom area of ​​the fixed column 100. The bottom pad 800 is used to distribute the load during the support process and prevent the fixed column 100 from sinking into the ground.

[0049] The bottom pad 800 is made of rigid material, while the top pad 300 is made of elastic material. The bottom pad 800 can be supported by steel plates or concrete blocks, which can distribute the load of the fixed column 100 and prevent ground settlement. The top pad 300 can be supported by rubber material. Rubber has good elasticity, which can buffer the impact load between the concrete structural member and the sliding column 200, reduce vibration and stress concentration. At the same time, in the early stage of the manufacture of the concrete structural member, the concrete strength is low, and the rubber top pad 300 can reduce the damage to the concrete structural member.

[0050] The lifting unit 400 includes a hydraulic cylinder that is vertically fixed to the bottom surface of the inner side of the slide groove 101. The output end of the hydraulic cylinder is fixedly connected to the bottom of the sliding column 200. The sliding column 200 is driven to move up and down by the hydraulic cylinder.

[0051] The hydraulic cylinders used in this application need to have strong support and load-bearing capacity, and heavy-duty engineering hydraulic cylinders are preferred.
