[0002] In various building structures and pipe gallery projects, dowel bar fixing devices are typically used to stably install the dowel bars within the pipe gallery slab to ensure effective load transfer. Taking a pipe gallery dowel bar fixing device disclosed in CN108532635B as an example, this design uses multiple structural ribs and fixing components to fix the dowel bars, significantly improving the installation quality. However, this design relies primarily on metal materials, resulting in a large overall weight, and the connection between the fixing components and the dowel bars is relatively complex, potentially affecting installation efficiency. Furthermore, due to the insufficient consideration of non-metallic materials, the device has limitations in corrosion resistance, making it difficult to meet long-term use requirements in special environments. Therefore, there is a need in the art for a dowel bar fixing device that can balance lightweight design, ease of installation, and corrosion resistance. Utility Model Content

[0022] This utility model provides a non-metallic force transmission rod fixing device, the structure of which is as follows: Figures 1 to 4 As shown in the accompanying drawings, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. In this embodiment, the device includes a support frame 1, a guide groove 2, a fixing clamp 3, an elastic clamping assembly 4, a limiting plate 5, a ball bearing 6, a ball bearing receiving groove 7, a slide rail 8, a base 9, a spacer 10, an adjusting screw 11, and a driving part 12. The connection relationship, positional relationship, and mutual cooperation relationship of these components will be described one by one below.
[0023] Example 1
[0024] The support frame 1 is the core load-bearing component of the entire device. It is made of non-metallic material and has a guide groove 2 extending along the installation direction of the force transmission rod. The purpose of the guide groove 2 is to provide a moving path for the fixing clamp 3 and ensure that the fixing clamp 3 maintains close contact with the force transmission rod during movement. The fixing clamp 3 is installed in the guide groove 2 via a sliding connector, and a set of ball bearings 6 is provided on each side.
[0025] The design of the ball bearing 6 allows the fixed clamp 3 to move smoothly within the guide groove 2 while reducing friction. Elastic clamping components 4 are provided above and below the fixed clamp 3, located between the fixed clamp 3 and the support frame 1, to apply pressure to the fixed clamp 3 in a direction perpendicular to the axis of the force transmission rod.
[0026] In addition, this pressure is provided by elastic elements, such as springs or elastic rubber blocks, to ensure that the fixing clamp 3 can always fit against the surface of the force transmission rod.
[0027] Therefore, to further enhance the stability of the fixing clamp 3, this utility model also includes a pair of limiting plates 5, which span the support frame 1, and the fixing clamp 3 is installed between these two limiting plates 5 via a sliding connector. Each plate of the limiting plate 5 is provided with a ball receiving groove 7, in which the ball 6 is embedded and can roll along the pressure direction. The design of the ball receiving groove 7 not only limits the range of movement of the ball 6, but also guides the direction of movement of the ball 6, thereby ensuring that the fixing clamp 3 always maintains close contact with the force transmission rod during movement.
[0028] To achieve synchronous movement of the limiting plate 5, this invention also includes at least one pair of slide rails 8, which are mounted on the base 9. The limiting plate 5 is installed on the base 9 via the slide rails 8 and can move synchronously along the installation direction of the force transmission rod. The base 9 is the basic component of the entire device, and it is fixedly connected to the support frame 1 via spacer columns 10, thereby raising the support frame 1 to a certain height. The number and distribution of spacer columns 10 are adjusted according to actual needs to ensure the overall stability of the device. The design of the slide rails 8 not only ensures the smooth movement of the limiting plate 5, but also prevents the limiting plate 5 from shifting or tilting during movement.
[0029] To accommodate the fixing requirements of force transmission rods of different diameters or materials, this utility model also includes an adjustment mechanism, which is set on the ball bearings 6 of the fixing clamp 3 acting on the limiting plate 5. Specifically, each plate of the limiting plate 5 is provided with a threaded through hole, and the adjustment mechanism is an adjusting screw 11, which passes through the threaded through hole and acts on the ball bearings 6 of the fixing clamp 3 in the pressure direction. By rotating the adjusting screw 11, the degree of clamping of the fixing clamp 3 on the force transmission rod can be adjusted, thereby meeting the needs of different application scenarios.
[0030] To improve the ease of operation of the device, this utility model also includes a drive unit 12, which is connected to the limiting plate 5 and drives the limiting plate 5 to move along the slide rail 8 by mechanical or electric means. The design of the drive unit 12 not only reduces the labor intensity of manual operation, but also ensures the uniformity and consistency of fixation.
[0031] The operating principle of this utility model is as follows: First, the force transmission rod is placed at the feed end of the guide groove 2, and the force transmission rod enters the clamping area of the fixing fixture 3 along the direction of the guide groove 2. Under the action of the elastic clamping component 4, the fixing fixture 3 applies pressure perpendicular to the axis of the force transmission rod, thereby achieving initial fixation of the force transmission rod. Subsequently, the clamping degree of the fixing fixture 3 on the force transmission rod is adjusted by adjusting the adjusting screw 11 to accommodate force transmission rods of different diameters or materials. After fixation is completed, the drive unit 12 drives the limiting plate 5 to move along the slide rail 8, thereby driving the fixing fixture 3 to move along the guide groove 2 to the next station. During this process, the balls 6 roll in the ball receiving groove 7 to ensure the smooth movement of the fixing fixture 3.
[0032] The force transmission rod of this invention is installed at an angle relative to the horizontal plane, and the angle design can meet the needs of specific application scenarios. For example, in some industrial equipment, the force transmission rod needs to be installed at a certain angle to match the working state of the equipment. By adjusting the height of the base 9 and the length of the spacer column 10, the installation direction of the force transmission rod can be flexibly adjusted.
[0033] The specific embodiments of this utility model have been described in detail above with reference to the accompanying drawings. In this embodiment, the connection relationships, positional relationships, and mutual cooperation relationships between the various components are fully disclosed, ensuring that those skilled in the art can implement this technology based on the contents of the specification.
[0034] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.
[0035] Implementation Case 2
[0036] In a utility tunnel project, dowel bars need to be fixedly installed within a 15° inclined slab. This scenario requires the fixing device to be lightweight, corrosion-resistant, and easy to operate, while also being able to accommodate dowel bars of different diameters. Therefore, the non-metallic dowel bar fixing device provided by this invention has been applied to this scenario.
[0037] First, the support frame 1 is connected and fixed to the base 9 via the spacer column 10, ensuring the entire device is stably placed on the construction site. The length of the spacer column 10 is adjusted according to actual needs, so that the direction of the dowel bar installation forms a 15° tilt angle relative to the horizontal plane. This tilt angle design meets the requirements of specific construction environments and facilitates the precise positioning and installation of the dowel bar subsequently.
[0038] Subsequently, the force transmission rod to be fixed is inserted from the feed end of the guide groove 2, allowing it to enter the clamping area of the fixing fixture 3 along the direction of the guide groove 2. During this process, the balls 6 on both sides of the fixing fixture 3 are embedded in the ball receiving grooves 7 on the limiting plate 5, and the rolling reduces friction, thereby ensuring that the fixing fixture 3 can move smoothly within the guide groove 2. At the same time, the elastic clamping assembly 4 applies pressure to the fixing fixture 3 in a direction perpendicular to the axis of the force transmission rod, so that the fixing fixture 3 always fits tightly against the surface of the force transmission rod, thus initially achieving the fixing of the force transmission rod.
[0039] Furthermore, to accommodate different diameters of the force transmission rod, the operator can adjust the clamping force of the fixing clamp 3 on the force transmission rod by rotating the adjusting screw 11. Specifically, the adjusting screw 11 passes through the threaded hole on the limiting plate 5 and acts on the ball bearing 6 of the fixing clamp 3 in the direction of pressure, thereby changing the clamping force of the fixing clamp 3 on the force transmission rod. This design allows the device to flexibly handle force transmission rods of different diameters or materials, significantly improving the applicability of the device.
[0040] Therefore, after the initial fixing of the force transmission rod is completed, the drive unit 12 is activated, driving the limiting plate 5 to move synchronously along the slide rail 8 via mechanical or electric means. The movement of the limiting plate 5 drives the fixing fixture 3 to move to the next station along the guide groove 2, while the balls 6 roll in the ball receiving groove 7, ensuring that the fixing fixture 3 maintains close contact with the force transmission rod throughout the entire movement. This process not only ensures the stability of the force transmission rod but also avoids wear problems caused by excessive friction.
[0041] Through the above steps, the force transmission rod is efficiently and stably fixed in the device and finally installed inside the pipe rack plate. The entire process demonstrates the advantages of this utility model device in terms of lightweight, corrosion resistance, and ease of operation. For example, the support frame 1 is made of non-metallic materials, which significantly reduces the overall weight and avoids the problem of easy corrosion of metallic materials in special environments; the design of the elastic clamping component 4 and the ball bearing 6 reduces friction and ensures the smooth movement of the fixing clamp 3; the introduction of the adjusting screw 11 allows the device to flexibly adapt to force transmission rods of different diameters, enhancing its applicability.
[0042] In summary, this utility model, through its reasonable structural design and functional configuration, successfully solves the problems of excessive weight, complex installation, and insufficient corrosion resistance in existing technologies, providing an efficient and reliable solution for fixing dowel bars in building structures and pipe gallery projects.
