Abstract
Description
Technical Field
[0001] This application relates to the technical field of positioning and installation of embedded parts in installation projects, and particularly to a positioning auxiliary device for embedded parts of track supports. Background Art
[0002] Embedded parts of track supports are components widely used in railway, bridge, and tunnel installation projects. The embedded parts mainly consist of embedded bars, bolts, and embedded steel plates. The spacing between the embedded parts is usually 1.25 - 1.5 meters, and the number of installed embedded bodies is extremely large. Their positioning and installation during the construction process have always been the key points and difficulties of the construction, and are also important factors affecting the construction efficiency. They usually need to be completed synchronously during the construction of the concrete foundation, that is, the embedded parts are embedded after the construction of the steel bar framework of the concrete foundation is completed and before the concrete is poured. The commonly used method in the prior art is as follows: First, manual measurement and positioning are carried out to determine the positions of each embedded part. Then, a leveling device is used to adjust the flatness of the embedded steel plate so that the embedded steel plate is suspended above the steel bar framework. After temporarily supporting and fixing the positioned embedded steel plate, the bottom embedded bars are welded to the steel bar framework to complete the process of positioning the embedded parts.
[0003] The above method cannot be flexibly adjusted for embedded steel plates of different sizes, and there is a hidden danger of uneven stress on the embedded parts. At the same time, in the case of an uneven construction foundation, the flatness of the embedded steel plate cannot be flexibly adjusted, resulting in a waste of a large amount of manpower and material resources in the installation and positioning process, low construction efficiency, and problems such as cumbersome installation and positioning, high construction cost, and large positioning errors.

Detailed Embodiments
[0027] To make the objectives, technical solutions, and advantages of the present disclosure clearer and more understandable, the following further describes the present disclosure in detail with reference to specific embodiments and the accompanying drawings.
[0028] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should have the ordinary meaning understood by those of ordinary skill in the art to which the present disclosure belongs.

[0029] To facilitate the understanding of the positioning auxiliary device for track support embedded parts provided by the embodiments of the present application, first, its application scenario will be described. Track support embedded parts are components widely used in railway, bridge, and tunnel installation projects. The embedded parts mainly consist of embedded bars, bolts, and embedded steel plates. The spacing between the embedded parts is usually 1.25 - 1.5 meters, and the number of embedded bodies to be installed is extremely large. Their positioning and installation during the construction process have always been the key points and difficulties of the construction, and are also important factors affecting the construction efficiency. They usually need to be completed synchronously during the concrete foundation construction process, that is, the embedded parts are embedded after the construction of the concrete foundation steel bar framework is completed and before the concrete pouring. The commonly used method in the prior art is as follows: First, manual measurement and positioning are carried out to determine the positions of each embedded part. Then, a leveling device is used to adjust the flatness of the embedded steel plate, so that the embedded steel plate is suspended above the steel bar framework. After temporarily supporting and fixing the positioned embedded steel plate, the bottom embedded bars are welded to the steel bar framework to complete the process of positioning the embedded parts.
[0030] The above method cannot be flexibly adjusted for embedded steel plates of different sizes, and there is a hidden danger of uneven force on the embedded parts. At the same time, in the case of an uneven construction foundation, the flatness of the embedded steel plate cannot be flexibly adjusted, resulting in a waste of a large amount of manpower and material resources in the installation and positioning process. The construction efficiency is low, and there are problems such as cumbersome installation and positioning, high construction cost, and large positioning error.
[0031] Specifically, in this embodiment, taking the positioning and installation of track supports in railway construction as an example, refer to Figure 1 and Figure 2 as shown in Figure 1 is a schematic structural diagram of the first embodiment of the positioning auxiliary device for track support embedded parts. In this embodiment, height adjustment screw groups 11 with adjustable heights are provided at the bottoms of the vertical rod bodies 10 of the gantry frame, and pulleys 12 are provided at the bottoms of the height adjustment screw groups 11. By presetting a slideway on the steel bar framework, the effect of sliding displacement is achieved through the cooperation of the pulleys 12 and the slideway, saving the physical consumption of construction workers for the installation of a large number of embedded parts. Figure 2 is a schematic structural diagram of the second embodiment of the positioning auxiliary device for track support embedded parts. Through Figure 2It can be seen that an extension rod 13 is provided at the bottom of the vertical rod 10 of the gantry frame body, and a height adjustment screw group 11 is also provided between the vertical rod 10 and the extension rod 13. Thus, for the steel bar group frame where the slideway cannot be installed, the construction worker holds the extension end of the rectangular frame 30 and transports it to the pre-positioned point to achieve the operation of leveling the embedded steel plate. Convenient leveling of the embedded steel plate can be achieved in both embodiments, reducing the unstable position factors during the welding process and reducing the deviation. Exemplarily, if the size of the embedded steel plate is 350mm×350mm and the designed width of the steel bar skeleton of the embedded part foundation is 500mm, the length and width of the positioning auxiliary device for the track support embedded part can be 700mm.
[0032] Combined Figure 1 with Figure 3 As shown in, the positioning auxiliary device for the track support embedded part provided by the embodiment of the present application includes: a gantry frame body that is oppositely arranged and slidably assembled on the steel bar skeleton, and a rectangular frame 30 connected between the two gantry frame bodies; the rectangular frame 30 is horizontally welded on the gantry frame body, and the transverse ends of the rectangular frame 30 extend to form a hand-held part, which is convenient for the construction worker to lift and displace the overall structure.
[0033] The oppositely arranged gantry frame bodies are important components for overall height adjustment and auxiliary width adjustment. Each gantry frame body includes two vertical rods 10 and a transverse rod 20 connected between the tops of the two vertical rods 10. The four corners of the rectangular frame 30 are welded to the four vertical rods 10 of the two gantry frame bodies. The overall connection performance is stable, providing reliable support for positioning the embedded part.
[0034] In the first embodiment of the present application, a height adjustment screw group 11 is assembled on each vertical rod 10, and a pulley 12 is assembled at the bottom of the height adjustment screw group 11. Quick adjustment is achieved, and corresponding adjustments are made for different construction heights. The height adjustment screw group 11 is a screw sleeve adjustment part. By correspondingly providing a right-handed thread and a left-handed thread at both ends of the screw sleeve, during the rotation of the screw sleeve, the threaded section on the vertical rod 10 and the threaded rod connected to the pulley 12 rotate correspondingly, achieving the purpose of moving away from and approaching each other.
[0035] Certainly, in the second embodiment of the present application, a height adjustment screw group 11 is assembled on each vertical rod 10, and an extension rod 13 is threadedly connected to the bottom of the height adjustment screw group 11. Thus, the threads at both ends of the screw sleeve are threadedly connected to the threaded section of the vertical rod 10 and the threaded section of the extension rod 13, and the thread directions of the threaded section of the vertical rod 10 and the threaded section of the extension rod 13 are opposite.
[0036] A width adjustment screw group 21 is horizontally arranged along the upper edge of the portal frame body. The width adjustment screw group 21 is arranged in the middle section of the transverse rod bodies 20 of the two portal frame bodies. As an auxiliary adjustment part, when the rectangular frame 30 is horizontally adjusted, it is synchronously and correspondingly adjusted, so as to improve the overall strength while ensuring high supporting performance.
[0037] Specifically, a first adjustment screw group 31 is assembled on two opposite first rods of the rectangular frame 30, a second adjustment screw group 32 is assembled on two opposite second rods of the rectangular frame 30, and ear hooks 50 are threadedly connected to both the two first rods and the two second rods. The width adjustment screw group 21 and the first adjustment screw group 31 on the same side are located on the same vertical line. During the synchronous adjustment process, the embedded parts steel plates of different sizes are matched and lifted. The first adjustment screw group 31 is arranged in the middle section of the two first rods; the second adjustment screw group 32 is arranged in the middle section of the two second rods. The adjustable range is expanded, and it can be matched and used for embedded steel plates of different sizes.
[0038] Moreover, the height adjustment screw group 11, the width adjustment screw group 21, the first adjustment screw group 31 and the second adjustment screw group 32 are all screw sleeve adjustment parts. The materials are convenient to obtain, the manufacturing process is simple, and the use performance is reliable, so no more details will be described here.
[0039] Combined with Figure 4 As shown in, at least two ear hooks 50 are threadedly connected to each first rod and / or each second rod. Multiple ear hooks 50 realize multi-point lifting of the embedded steel plate. After stable positioning, the embedded steel bars are welded to the steel bar framework. The ear hook 50 is an inverted "7"-shaped hook body, and the ear hook 50 is connected to the two first rods and / or the two second rods through bolt parts. By adjusting the height of the ear hook 50, the embedded steel plate is in a horizontal state before the welding process.
[0040] In addition, a guiding and positioning rod 40 is slidably connected between the two first rods, and the two portal frame bodies are parallel to the two first rods. Of course, one guiding and positioning rod 40 or two guiding and positioning rods 40 can be slidably connected between the two first rods, and one guiding and positioning rod 40 or two guiding and positioning rods 40 can also be slidably connected between the two second rods. Exemplarily, when one guiding and positioning rod 40 is slidably connected between the two first rods, sliding sleeves 41 are symmetrically arranged on both of the two first rods, and the guiding and positioning rod 40 is sleeved on the sliding sleeves 41. The guiding and positioning rod 40 provides a guiding stroke and ensures a reliable sliding range during longitudinal adjustment.
[0041] As can be seen from the above structure, when installing large-scale embedded parts, after initially positioning the installation height of the embedded parts through the height adjustment screw group 11, by adjusting the first adjustment screw group 31 and the second adjustment screw group 32, multiple ear hooks 50 respectively lift the embedded steel plate. Place a spirit level on the embedded steel plate, and adjust the height of the corresponding ear hook 50 by observing the spirit level until the installation standard is reached, so that the embedded bars are welded to the steel bar framework for positioning. Subsequently, the construction workers lift or push the positioning auxiliary device to move to the next installation position. Only by adjusting the level of the multiple ear hooks 50 lifting the embedded steel plate can rapid and accurate positioning be achieved, the construction progress be accelerated, and the positioning error be reduced.
[0042] In this application, through height adjustment, lateral adjustment, and longitudinal adjustment, embedded parts of various sizes can be matched, improving the convenience of embedded part positioning, accelerating the construction progress, and reducing the positioning error.
