Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and more specifically, to a high-efficiency temperature measuring device for large-volume concrete. Background Technology

[0002] Concrete pouring and temperature measurement are crucial steps in ensuring the quality of large-volume concrete construction. By monitoring concrete temperature changes in real time, cracks can be effectively prevented and curing measures can be optimized.

[0003] Existing concrete temperature measuring devices, such as the Chinese utility model patent with application number 202420026681.8 entitled "A High-Efficiency Large-Volume Concrete Temperature Measuring Device," use a lifting device to move the temperature measuring equipment vertically, thereby performing multi-point temperature measurement on large-volume concrete. However, it still has the following drawbacks in use: 1. When measuring temperature, it can only measure the temperature of one side of the large-volume concrete, and the temperature measuring efficiency needs to be improved; 2. During the position adjustment process, the measuring head of the temperature measuring device generates static friction with the surface of the large-volume concrete, which can easily damage the measuring head of the temperature measuring device.

[0004] Therefore, under the current circumstances, it is necessary to propose an efficient temperature measurement device for large-volume concrete to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of this, the present invention proposes a high-efficiency temperature measuring device for large-volume concrete, which aims to solve the problems existing in the background technology, so that the device can perform multi-point temperature measurement on multiple sides of large-volume concrete, greatly improving the temperature measurement efficiency, and is not easily damaged when adjusting the height.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency, large-volume concrete temperature measuring device includes a base plate. A height-adjustable component is installed near the end of the front side of the top surface of the base plate. An installation plate is mounted on the upper part of the front side of a movable seat within the height-adjustable component, allowing for vertical position adjustment. The installation plate is horizontally positioned, and its rear side is fixedly connected to the movable seat at its midpoint. Several temperature measuring components are evenly spaced along the length of the installation plate on its front side. The installation plate is hollow, and a bidirectional cylinder is installed in the center of its cavity. Two piston rods in the bidirectional cylinder are connected to two movable plates located on the left and right sides of the installation plate via corresponding connecting rods. The plate and the connecting rod are at the same height and perpendicular to each other's central axis. Several temperature measuring components are installed at equal intervals along the length of each of the two movable plates on their opposite surfaces. Each temperature measuring component includes a temperature probe and two guide components. The temperature probe and the guide components are installed on the corresponding surfaces of the mounting plate or the movable plate, and the two guide components are respectively located on both sides of the corresponding temperature probe along the length of the mounting plate or the movable plate. A battery box is also installed on the top surface of the base plate. A controller is electrically connected to the battery box, and the controller is electrically connected to the height adjustment component, the bidirectional cylinder, and the temperature probe.

[0008] Preferably, the height adjustment component includes the movable seat, the fixed seat, the screw, and the motor. The lower end of the fixed seat is connected to the top surface of the base plate. The movable seat is slidably connected in the inner cavity with an upper opening in the fixed seat. The upper end of the movable seat extends upward and protrudes from the opening in the fixed seat, and the fixed seat restricts the rotation of the movable seat. The screw is vertically rotatably installed in the fixed seat. The screw is threadedly connected to a threaded hole on the lower end face of the movable seat. A first bevel gear is fixedly connected to the lower end of the screw. The motor is installed on the lower side of the outer wall of the fixed seat. The output end of the motor extends into the fixed seat and is fixedly connected to a second bevel gear. The first bevel gear and the second bevel gear mesh with each other.

[0009] Preferably, each piston rod in the bidirectional cylinder is connected to a movable block at its end. The movable block is slidably installed in the corresponding side cavity of the mounting plate. The side of the movable block away from the corresponding piston rod is fixed to the connecting rod. The other end of the connecting rod extends horizontally to the outside of the mounting plate and is connected to the rear end of the movable plate on the corresponding side.

[0010] Preferably, the inner wall of the mounting plate is provided with a limiting structure that restricts the movable block to slide only along the length direction of the mounting plate.

[0011] Preferably, the guide component includes a positioning sleeve, a sliding rod, and a ball bearing. One end of the positioning sleeve is connected to the mounting plate or the movable plate, and the sliding rod is slidably connected in the inner cavity of the other end. The ball bearing is rolled on the end of the sliding rod that protrudes from the positioning sleeve. A spring is also provided in the inner cavity of the positioning sleeve, and the two ends of the spring are respectively connected to the inner wall of the positioning sleeve and the corresponding ends of the sliding rod. When the spring in the positioning sleeve is in its natural state and the ball bearing on the sliding rod is in contact with the side of the large-volume concrete column, there is a gap between the detection end of the temperature probe and the concrete surface.

[0012] Preferably, a push handle is installed on the rear side of the base plate.

[0013] Preferably, a self-locking caster wheel is provided at each of the four corners of the lower end face of the base plate.

[0014] Compared with existing technologies, this utility model provides a high-efficiency temperature measuring device for large-volume concrete, which has the following advantages:

[0015] Beneficial effects:

[0016] 1. When using this utility model device, the temperature measuring component on the mounting plate first comes into contact with one side of the large volume concrete. At the same time, the bidirectional cylinder adjusts the relative position between the two movable plates so that the temperature measuring component on the movable plate comes into contact with the side of the large volume concrete. Then, the height adjustment component adjusts the height so that the device can measure the temperature at multiple points on multiple sides of the large volume concrete, which greatly improves the temperature measurement efficiency.

[0017] 2. When the height of this utility model device is adjusted, the ball bearings on the guide component roll and connect with the side of the concrete to guide the movement of the temperature probe. At the same time, the spring in the positioning sleeve moves outward a certain distance when the slide rod is not subjected to external force, so that the temperature probe does not stick to the concrete surface, avoiding static friction during height adjustment and preventing damage to the temperature probe.

[0027] Example:

[0028] See Figures 1-4This embodiment provides a high-efficiency large-volume concrete temperature measuring device, including a base plate 1. A height adjustment component is installed on the front side of the top surface of the base plate 1 near its end. An installation plate 3 is installed on the upper part of the front side of a movable seat 2 within the height adjustment component, allowing for vertical position adjustment. The installation plate 3 is horizontally positioned, and its rear side is fixedly connected to the movable seat 2 at the middle. Several temperature measuring components are evenly spaced along the length of the installation plate 3 on its front side. The installation plate 3 is hollow, and a bidirectional cylinder 4 is installed in the center of its inner cavity. Two piston rods 5 in the bidirectional cylinder 4 are connected to two movable plates 7 located on the left and right sides of the installation plate via corresponding connecting rods 6. The movable plates 7 and connecting rods 6 are at the same height and their central axes are perpendicular. Several temperature measuring components are evenly spaced along the length of each movable plate 7 on their opposite surfaces. The bidirectional cylinder 4 can adjust the relative position between the two movable plates 7.

[0029] The temperature measuring component includes a temperature measuring probe 8 and two guide components 9.

[0030] A battery box 10 is also installed on the top surface of the base plate 1. The battery box 10 is electrically connected to a controller 11, which is electrically connected to the height adjustment component, the bidirectional cylinder 4, and the temperature probe 8.

[0031] This invention can perform multi-point temperature measurement on multiple sides of large-volume concrete, which greatly improves the temperature measurement efficiency, and the temperature measurement equipment is not easily damaged when adjusting the height.

[0032] Meanwhile, the bidirectional cylinder used in this utility model can be purchased directly from the market, or the structure of the bidirectional cylinder can be referred to the utility model patent with authorization announcement number CN 203476883 U, entitled Bidirectional Synchronous Reciprocating Cylinder, or the utility model patent with authorization announcement number CN 209903240 U, ​​entitled A Bidirectional Integrated Cylinder.

[0033] In a further specific embodiment, see [link to relevant documentation]. Figure 1 , Figure 3The height adjustment component includes a movable seat 2, a fixed seat 12, a screw 13, and a motor 14. The lower end of the fixed seat 12 is connected to the top surface of the base plate 1. The movable seat 2 is slidably connected to the inner cavity with an upper opening in the fixed seat 12. The upper end of the movable seat 2 extends upward and protrudes from the opening in the fixed seat, and the fixed seat 12 restricts the rotation of the movable seat 2. The screw 13 is vertically rotatably installed inside the fixed seat 12. The screw 13 is threadedly connected to a threaded hole on the lower end face of the movable seat. A bevel gear 15 is fixedly connected to the lower end of the screw 13. The motor 14 is installed on the lower side of the outer wall of the fixed seat 12. The output end of the motor 14 extends into the fixed seat 12 and is fixedly connected to a bevel gear 16. The bevel gear 15 and the bevel gear 16 mesh with each other. In this embodiment, the cross-sections of both the fixed seat 12 and the movable seat 2 are rectangular.

[0034] In this embodiment, each piston rod 5 in the bidirectional cylinder 4 is connected to a movable block 17 at its end. The movable block 17 is slidably installed in the corresponding side cavity of the mounting plate 3. The movable block 17 is fixedly connected to a connecting rod 6 on the side away from the corresponding piston rod 5. The other end of the connecting rod 6 extends horizontally to the outside of the mounting plate and is connected to the rear end of the movable plate 7 on the corresponding side.

[0035] Furthermore, the inner wall of the mounting plate 3 is provided with a limiting structure that restricts the movable block 17 to slide only along the length of the mounting plate, so as to ensure the smoothness of the movement of the movable block 17 and the connecting rod 6, and thus ensure the smoothness of the movement of the movable plate 7.

[0036] In a further specific embodiment, the guide component 9 includes a positioning sleeve 18, a sliding rod 19, and a ball bearing 20. One end of the positioning sleeve 18 is connected to the mounting plate 3 or the movable plate 7, and the sliding rod 19 is slidably connected in the inner cavity of the other end. The ball bearing 20 is rolled on the end of the sliding rod 19 that protrudes from the positioning sleeve 18. A spring 21 is also provided in the inner cavity of the positioning sleeve 18. The two ends of the spring 21 are respectively connected to the inner wall of the positioning sleeve and the corresponding ends of the sliding rod 19. When the spring 21 in the positioning sleeve 18 is in its natural state and the ball bearing 20 on the sliding rod 19 is in contact with the side of the large-volume concrete column, there is a gap between the detection end of the temperature probe 8 and the concrete surface. That is, at this time, the temperature measuring end of the temperature probe 8 is not in contact with the concrete surface.

[0037] Furthermore, a push handle 22 is installed on the rear side of the base plate 1; a self-locking universal wheel 23 is provided at each of the four corners of the lower end face of the base plate 1.

[0038] The working process of this utility model:

[0039] In use, the base plate 1 is pushed to one side of the large-volume concrete column using the push handle 22 and the self-locking universal wheels 23, so that the temperature measuring components on the mounting plate 3 are in contact with the front of the large-volume concrete column. Then, the piston rods 5 on both sides of the bidirectional cylinder 4 retract, causing the movable block 17 to slide relative to each other within the mounting plate 3. The movable block 17 drives the connecting rod 6 to move, which in turn drives the movable plate 7 to move, so that the temperature measuring components on both sides of the movable plate 7 are in contact with the sides of the large-volume concrete column. This utility model device, by setting multiple temperature measuring components in different positions, can simultaneously perform multi-point temperature measurement on multiple sides of a large-volume concrete column.

[0040] During temperature measurement, the large-volume concrete column first comes into contact with the ball bearing 20. The ball bearing 20 is squeezed and drives the slide rod 19 to move into the positioning sleeve 18. At this time, the temperature probe 8 comes into contact with the side of the large-volume concrete column to measure the temperature.

[0041] When vertical adjustment of the temperature measurement position is required, the positions of the mounting plate 3 and the movable plate 7 should be adjusted first so that the spring 21 inside the positioning sleeve 18 is no longer compressed by external force. Under the action of the spring's rebound force, the slide rod 19 moves outward from the positioning sleeve 18. At this time, the ball bearing 20 on the slide rod 19 is in contact with the side of the large-volume concrete column. In this way, when adjusting the height, the ball bearing 20 rolls on the side of the large-volume concrete column, ensuring the stability of the position adjustment. At the same time, it can also avoid static friction between the detection end of the temperature probe 8 and the side of the large-volume concrete column, which could cause damage to it.

[0042] When the temperature measuring component on the movable plate 7 comes into contact with the side of the large-volume concrete column and begins temperature measurement, the motor 14 rotates, driving the second bevel gear 16 to rotate. The second bevel gear 16 drives the first bevel gear 15, which meshes with it, to rotate. The first bevel gear 15 drives the screw 13 to rotate, and the screw 13 drives the movable seat 2, which is threadedly connected to its bottom surface, to move within the fixed seat 12. The length of the movable seat 2 protruding from the fixed seat 12 is adjusted, and the movable seat 2 drives the mounting plate 3 to move vertically. The mounting plate 3 then drives the movable plate 7 to move, so that the temperature measuring components on the mounting plate 3 and the movable plate 7 move vertically simultaneously, thereby performing comprehensive temperature measurement on different heights of the large-volume concrete column.

[0043] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
