Description

Technical Field

[0001] The utility model belongs to the field of gas meter production equipment, and in particular relates to a batch transport rack for processing upper shells of gas meters. Background Art

[0002] Gas meters are widely used in daily life and manufacturing industries to accumulate natural gas usage. Their installation environments are different, requiring anti-corrosion treatment on the surface of the meter case. The most common treatment is plastic spraying. In this process, the meter case needs to be cleaned first, and then the paint is sprayed onto the surface of the workpiece under the action of an electric field to form a powdery coating, which is then subjected to high-temperature baking and other treatments to form a protective coating.

[0003] During the processing, special hangers are required to hang the meter cases and transfer them to different workstations through conveyor lines. In the prior art, such as the patent number "201920500655.3", named "A processing line for a gas meter case", and the patent number "201920477218.4", named "A hook for spraying plastic on the upper shell of a gas meter case", the applicant found in the research that in the actual production process, the hangers used still have poor stability and large shaking amplitude, especially when the meter cases are placed in batches, the shaking is greater, which can easily cause resonance and lead to decoupling, seriously affecting production efficiency. Utility Model Content

[0004] In view of this, the utility model provides a gas meter upper shell processing batch transportation rack to solve the problem in the prior art that the batch transportation of gas meter upper shells is unstable, which affects the production and processing efficiency.

[0005] The technical solution is as follows:

[0007] The uppermost horizontal hanging rod is provided with two oblique connecting rods distributed in a triangle therewith, and the vertices of the two oblique connecting rods are connected with extension rods, and the top of the extension rods is provided with a hanging joint;

[0008] The horizontal hanging rod is provided with hook components evenly distributed along the length direction thereof, and each group of the hook components includes at least two hooks arranged in parallel.

[0009] The above solution can meet the needs of batch shell mounting, and has good overall structural stability. It is also easy to coordinate with the bracket structure to improve transportation stability, fully reduce transportation shaking, and maintain the stability of the upper shell posture.

[0010] Preferably, the hook is connected to the horizontal hanging rod through a support rod, the support rod is horizontally arranged and perpendicular to the horizontal hanging rod, and its extension direction is opposite to that of the hook;

[0011] The hook includes an integrally formed downwardly inclined portion, a horizontal portion, and an upwardly inclined portion, wherein the upper end of the downwardly inclined portion is connected to the end of the support rod, and the lower end thereof extends obliquely toward the side where the horizontal hanging rod is located, the horizontal portion and the horizontal hanging rod are perpendicular to each other, and the upwardly inclined portion extends upwardly obliquely from the end of the horizontal portion, and the angle between the upwardly inclined portion and the horizontal portion is 35°-45°. With the above scheme, the structural hook has a good supporting capacity, meets the oblique support requirements for the upper shell, and can offset the oblique pressure, reduce deformation, and is conducive to extending the overall service life of the hanger.

[0012] Preferably, in the same hook assembly, the horizontal portion of at least one hook has a bifurcated portion, the bifurcated portion is perpendicular to the horizontal portion and extends obliquely toward the space between the two hooks, and its apex is lower than the apex of the upward inclined portion. With the above solution, the bifurcated portion and the apex of the two upward inclined portions form an inclined triangular support, which is conducive to further improving the support stability of the shell.

[0013] As a preferred embodiment, in the same hook assembly, the vertical distance between the vertices of the two hooks' upwardly inclined parts is adapted to the distance between the two vertices in the width direction of the upper shell of the gas meter. With the above solution, when mounted, the vertices of the upwardly inclined parts are close to the corner vertices of the upper shell, which can reduce the range of movement of the upper shell, thereby improving the stability of the upper shell.

[0014] As a preferred embodiment, the apex of the bifurcation is located on the middle vertical plane of the two hooks in the same group, and the horizontal vertical distance between the apex of the bifurcation and the apex of the upward inclined portion is 1 / 2 to 2 / 3 of the depth of the upper shell of the gas meter. The above solution can ensure that the inclination angle of the upper shell is in a relatively appropriate position, further improving the stability of the mounting, transportation, and cleaning spraying process.

[0015] As a preferred embodiment, the upwardly inclined portion and the bifurcated portion are both made of round steel, and each vertex is in a cone shape. The above solution can reduce the contact area with the shell and improve the surface treatment quality.

[0016] As a preferred embodiment, the suspension joint is a double-head structure. The above solution can improve the suspension stability and prevent swaying in the moving direction.

[0017] As a preferred embodiment, there are only two vertical connecting rods, which are symmetrically arranged relative to the apex of the oblique connecting rod and are respectively close to the two ends of the horizontal hanging rod. The above solution ensures the stability of the overall structure and reduces the weight at the same time.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] refer to Figures 1 to 6 The gas meter upper shell processing batch transport rack shown mainly includes a plurality of horizontal hanging rods 210 distributed in a vertical array, and at least two vertically arranged vertical connecting rods 220, and the vertical connecting rods 220 are fixed to all the horizontal hanging rods 210 at the same time.

[0028] The uppermost horizontal hanging rod 210 is provided with two oblique connecting rods 230 distributed in a triangle therewith, and the vertices of the two oblique connecting rods 230 are connected with extension rods 240, and the top of the extension rod 240 is provided with a suspension joint 241 matching the conveyor belt 100. In this embodiment, the suspension joint 241 is a double-headed structure, which can improve the suspension stability. The vertical connecting rods 220 have and only have two vertical connecting rods 220, and the two vertical connecting rods 220 are symmetrically arranged relative to the extension rods 240 and are respectively close to the two ends of the horizontal hanging rod 210. The triangular distribution of the oblique connecting rods 230 also facilitates the bracket to accommodate the device to flexibly clamp it, thereby improving the overall stability of the bracket when mounting the upper shell.

[0029] The cross-hanging rod 210 has hook components evenly distributed along its length, and each set of hook components includes at least two parallel hooks 250. As shown in the figure, the hook 250 is connected to the cross-hanging rod 210 through a support rod 260, and the support rod 260 is horizontally arranged and perpendicular to the cross-hanging rod 210, and its extension direction is opposite to the extension direction of the hook 250.

[0030] The hook 250 includes an integrally formed downwardly inclined portion 251, a horizontal portion 252 and an upwardly inclined portion 253, wherein the upper end of the downwardly inclined portion 251 is connected to the end of the support rod 260, and the lower end thereof extends obliquely toward the side where the cross-hanging rod 210 is located, and the angle α between the downwardly inclined portion 251 and the horizontal portion is approximately 45°-85°, and 80° is preferably selected in this embodiment. The horizontal portion 252 is perpendicular to the cross-hanging rod 210, and the upwardly inclined portion 253 extends obliquely upward from the end of the horizontal portion 252, and the angle β between it and the horizontal portion 252 is approximately 35°-45°, and 40° is preferably selected in this embodiment. In this way, the hook 250 has better supporting capacity and lateral anti-deformation capacity, which is beneficial to extending its service life.

As shown in the figure, the forked portion 254 is perpendicular to the horizontal portion 252 and extends obliquely toward the space between the two hooks 250. Its apex is lower than the apex of the inclined portion 253. In this way, when the upper shell of the gas meter is placed on the hook assembly, it is actually supported at three points and is in an inclined posture with the opening facing downward, which is conducive to cleaning and spraying operations.

[0032] In the same hook assembly, the vertical distance between the vertices of the inclined portions 253 of the two hooks 250 is adapted to the distance between the two vertices in the width direction of the gas meter upper shell. In this way, when supporting, the vertices of the inclined portions 253 are close to the top angle of the gas meter upper shell, which is beneficial to further improve the stability of the gas meter upper shell.

[0033] In a specific implementation, the apex of the forked portion 254 is located on the middle vertical plane of the two hooks 250 in the same group.

[0034] In addition, in this embodiment, the inclined portion 253 and the forked portion 254 are both made of round steel material, and each of the vertices is cone-shaped. The hook 250 and the support rod 260, the horizontal hanging rod 210 and the vertical connecting rod 220, and the oblique connecting rod 230 and the vertical connecting rod 220 are all fixed by welding.
