Description

Technical Field

[0001] The utility model relates to the technical field of bracket structures, and particularly relates to an adjustable gantry bracket. Background Art

[0002] In a production line, most of the gantry brackets used are hyperstatic structures, and the inflection points are usually rigidly connected. Once the gantry bracket is installed, it cannot be adjusted, which has obvious limitations in practical applications. For example: 1. When a detection mechanism is suspended in the form of a gantry bracket, if there is a mismatch in the spatial position between the detection mechanism and the object to be detected, since the traditional gantry bracket cannot be adjusted, the spatial position of the wire passing transportation equipment needs to be adjusted to match the detection mechanism. 2. For a detection mechanism that requires high-precision positioning, the traditional rigid connection and fixed structure may not meet the requirements, resulting in an increase in the uncertainty of the detection results. 3. If a detection mechanism is installed outside the space of the existing transportation equipment, higher requirements are imposed on the positioning requirements and installation horizontal dimensions of the gantry bracket, and repeated adjustments or even secondary processing are required. Content of the Utility Model

[0003] The utility model provides an adjustable gantry bracket to solve the technical problem that the spatial dimensions of the traditional gantry bracket cannot be finely adjusted.

[0004] To solve the above problems, an adjustable gantry bracket provided by the utility model adopts the following technical solutions:

[0005] An adjustable gantry bracket includes a cross beam, and the cross beam is supported on the top surfaces of a first upright post and a second upright post.

[0006] A deflection pin shaft is arranged on one side of the cross beam, and a pin shaft hole is arranged at the top of the first upright post to cooperate with the deflection pin shaft.

[0007] A deflection part is fixedly arranged on the other side of the cross beam, an adjustment part is fixedly arranged on the side surface of the top of the second upright post, and an adjustment bolt facing the deflection part is assembled on the adjustment part to abut or push away the deflection part against the adjustment part.

[0008] By screwing the adjustment bolt to adjust the distance between the adjustment part and the deflection part, the cross beam is pushed to rotate around the pin shaft hole to realize the deflection adjustment of the cross beam.

[0009] Since one side of the crossbeam is connected to the first vertical column through a deflection pin shaft, when the adjustment bolt pushes one side of the crossbeam, the crossbeam will rotate around the pin shaft hole, thereby realizing the deflection adjustment of the crossbeam, improving the versatility and adaptability of the gantry support. Through the fine-tuning function of the adjustment bolt, the deflection angle of the crossbeam can be accurately controlled to ensure the precise positioning of the detection device or painting mechanism. This adjustable gantry support design is particularly suitable for the installation of detection devices or painting mechanisms that require high-precision positioning, such as in the fields of cast pipe production lines, precision machining, and automated assembly lines, which can significantly improve production efficiency and product quality. Through a simple structure and ingenious design, the perfect combination of flexibility and stability of the gantry support is achieved.

[0010] As a preferred technical solution of the present utility model, the connection manner between the crossbeam and the first vertical column and the second vertical column is flange connection. The flange connection includes a crossbeam flange plate and a column flange plate arranged opposite to each other. The crossbeam flange plate is provided with a first long hole, and the column flange plate is provided with a second long hole. The corresponding first long hole and the second long hole are arranged perpendicular to each other. The crossbeam connection flange and the column connection flange are provided with long holes perpendicular to each other in the length direction to ensure that after the crossbeam rotates, the two connection flanges can still be reliably connected by bolts to ensure the accuracy and reliability of the equipment.

[0011] As a preferred technical solution of the present utility model, the first long holes are uniformly arranged on both sides of the crossbeam flange plate. The gap between the first long holes located on both sides of the crossbeam flange plate is greater than the width of the crossbeam, and the first long hole is a long hole along the width direction of the crossbeam.

[0012] As a preferred technical solution of the present utility model, the flange connection further includes a plurality of horizontal adjustment bolts. The horizontal adjustment bolts pass through one side flange plate of the flange connection and abut against the surface of the other side flange plate; the gap between the two opposite flange plates is adjusted by the horizontal adjustment bolts to realize the fine adjustment of the crossbeam in the vertical direction. By rotating the adjustment bolt, its extended length can be changed, thereby adjusting the relative position between the two side flange plates to realize the fine adjustment of the crossbeam in the vertical direction.

[0013] As a preferred technical solution of the present utility model, there are two adjustment parts, which are symmetrically arranged on the side surface of the second vertical column, and the deflection part is located in the middle of the two adjustment parts.

[0014] As a preferred technical solution of the present utility model, the adjustment part is arranged in a plate-like structure, and the deflection part is a baffle structure.

[0015] As a preferred technical solution of the present utility model, it further includes a base and an adjustment device. Both the first vertical column and the second vertical column are fixed on the base through the adjustment device. The adjustment device includes:

[0016] The first adjusting plate is a plate-shaped body fixedly arranged at the bottom of the first upright column or the second upright column, and at least two bolt holes are arranged circumferentially on the first adjusting plate;

[0017] The second adjusting plate has a plate-like structure, one side is fixedly connected to the base, and the other side is in clearance fit with the first adjusting plate;

[0018] The base adjusting bolt is arranged in the bolt hole and the bottom end thereof contacts the second adjusting plate, and adjusting nuts are arranged on both sides of the first adjusting plate for the base adjusting bolt to be adaptively installed with the adjusting bolt.

[0019] As a preferred technical solution of the present utility model, the adjusting device further includes a horizontal adjusting bolt which penetrates through the first adjusting plate and abuts against the upper surface of the second adjusting plate; the gap between the first adjusting plate and the second adjusting plate is adjusted by the horizontal adjusting bolt to achieve fine adjustment of the cross beam in the vertical direction.

[0020] The beneficial effects are as follows:

[0021] To overcome the shortcoming that the existing gantry bracket cannot be finely adjusted, the inventor adopts the most basic simply supported beam mechanism, installs deflection pin shafts and deflection parts on both sides at the cross beam, and corresponding pin shaft holes and adjusting parts are arranged on the two upright columns. The adjusting parts are provided with adjusting bolts abutting against the deflection parts to achieve deflection adjustment of the cross beam; horizontal adjusting bolts are arranged at the bottom and top of the upright columns to facilitate adjustment of the cross beam in the vertical direction. Through the above improvements, the structure of the gantry bracket can finely adjust the spatial dimensions to adapt to the detection accuracy or installation requirements.

Specific implementation manner

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0032] In the cast pipe production line, detecting the workpieces being produced is an important part of ensuring product quality. Especially with the increasing requirements for improving quality and efficiency, the detection requirements for product quality are gradually emphasized, and the precision requirements for detection equipment are further deepened.

[0033] In the prior art, the inventor found that for long - shaped workpieces, the detection mechanism is usually suspended in the form of a gantry support. In addition to the usual detection structure, some support systems for painting also use the gantry support form. However, traditional gantry supports are all statically indeterminate structures, usually rigidly connected at the inflection points and cannot be adjusted after installation. It is necessary to adjust the spatial position of the wire - passing transportation equipment to match the detection mechanism. Moreover, if a detection mechanism is installed outside the space of the existing transportation equipment, higher requirements for the positioning of the gantry support and the installation horizontal dimensions are required, and repeated adjustments or even secondary processing are needed. Therefore, there is an urgent need for a gantry support structure that can finely adjust the spatial dimensions to meet the detection accuracy or installation requirements.

[0034] To overcome the disadvantage that the existing gantry bracket cannot be finely adjusted, the inventor adopts the most basic simply supported beam mechanism, installs a deflection pin shaft and a deflection part at the cross beam, and sets a pin hole and an adjustment part on the column that are adapted to it to realize the deflection adjustment of the cross beam; horizontal adjustment bolts are provided at both the bottom and the top of the column to facilitate the adjustment of the cross beam in the vertical direction, and the above improvements are made to meet the detection accuracy or installation requirements.

[0035] After introducing the basic principle of the present invention, various non-limiting embodiments of the present invention will be specifically introduced below. The number of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction without any limiting meaning.

[0036] Next, with reference to several representative embodiments of the present invention, the principle and spirit of the present invention will be elaborated in detail.

[0037] Embodiment 1:

[0038] As Figures 1-6 shown, an adjustable gantry bracket includes:

[0039] A base;

[0040] An adjusting device 700, vertically fixed on the base;

[0041] A first column 200, vertically fixed on the base through the adjusting device 700, and a pin hole 210 is provided at the top of the first column 200;

[0042] A second column 300, adjacent to the first column 200, is vertically fixed on the base through the adjusting device 700; an adjusting part 310 is fixedly provided on the side of the top of the second column 300, the adjusting part 310 protrudes towards the direction of the first column 200, and an adjusting bolt 320 is assembled on the adjusting part 310;

[0043] A cross beam 100, supported on the top surfaces of the first column 200 and the second column 300, and has a simply supported beam stress structure; a deflection pin shaft 120 is provided on one side of the cross beam 100 close to the first column 200, and the deflection pin shaft 120 is matched with the pin hole 210; a deflection part 110 is provided at the bottom of the other side of the cross beam 100, and the deflection part 110 extends towards the base direction, and the adjusting bolt 320 passes through the adjusting part 310 and abuts against the deflection part 110; by turning the adjusting bolt 320, the distance between the adjusting part 310 and the deflection part 110 can be adjusted to push one side of the cross beam 100 to deflect, and the other side of the cross beam 100 rotates around the pin hole 210 to realize the deflection adjustment of the cross beam 100.

[0044] In this example, the connection method between the cross beam 100 and the first column 200 and the second column 300 is flange connection; the flange connection includes a cross beam flange and a column flange (hereinafter referred to as flange) arranged oppositely, asFigure 6 As shown, a first long hole 130 is provided on the beam flange. The first long holes 130 are evenly arranged on both sides of the beam flange. The gap between the first long holes 130 on both sides of the beam flange is greater than the width of the beam 100. The first long holes 130 are long holes extending along the width direction of the beam 100. A second long hole is provided on the column flange. The second long hole is arranged corresponding to the first long hole 130 and is fastened by bolts. The first long hole 130 and the second long hole are arranged perpendicular to each other, that is, the second long hole is a long hole extending along the length direction of the beam 100. The flange connection is adjusted and fixed by means of the long holes when the beam 100 deflects. When the beam 100 deflects and is adjusted, the position in the length direction will shift, and the corresponding bolt holes on the flange will deviate. In order to adapt to the above situation, the first long hole 130 and the second long hole are provided.

[0045] After the first column 200 and the second column 300 are adjusted, the horizontal position of the beam 100 may not match during use. In order to overcome this problem and be able to adjust, a horizontal adjustment bolt 150 is also provided on one side of the flange connection. The horizontal adjustment bolt 150 passes through the flange on one side of the flange connection and abuts against the surface of the flange on the other side. The horizontal adjustment bolt 150 is threadedly connected with the flange it passes through. During the process of screwing the horizontal adjustment bolt 150, it will inevitably push against the flange on the other side. On the premise of loosening the bolts originally used for fixing, the gap between the two flanges can be increased to achieve the effect of secondary adjustment.

[0046] As Figure 5 shown, the adjusting device 700 includes:

[0047] A first adjusting plate 740, which is a plate-shaped body located at the bottom of the first column 200 and the second column 300 and fixedly connected to the first column 200 and the second column 300. Two or more bolt holes are provided around the first adjusting plate 740 in the circumferential direction of the first column 200 and the second column 300;

[0048] A second adjusting plate 750, which has a plate-shaped structure. One side is fixedly connected to the base, and the other side is in clearance fit with the first adjusting plate 740;

[0049] The base adjustment bolt 710 passes through the bolt hole and contacts the second adjustment plate 750. The base adjustment bolt 710 is provided with an upper adjustment nut 720 on the upper side of the first adjustment plate 740, and the base adjustment bolt 710 is provided with a lower adjustment nut 730 on the lower side of the first adjustment plate 740. The inventors consider that the gantry bracket will have two adjustment processes during the actual operation. When the first column 200 and the second column 300 are initially installed, the first adjustment can be completed by referring to their top surface elevations, and then the first column 200 and the second column 300 are fixed; then the crossbeam 100 is installed. After the crossbeam 100 is installed, the top surface elevations of the first column 200 and the second column 300 can still be adjusted by the adjustment device 700, so that the level of the crossbeam 100 meets the use requirements of the detection mechanism.

[0050] like Figure 2 As shown, in order to make the adjustment of the cross beam 100 more convenient, the adjustment device 700 is further provided with a horizontal adjustment bolt 150, which passes through the first adjustment plate 740 and abuts against the upper surface of the second adjustment plate 750; the gap between the first adjustment plate 740 and the second adjustment plate 750 is adjusted by the horizontal adjustment bolt 150 to achieve fine adjustment of the cross beam 100 in the vertical direction. The horizontal adjustment bolts 150 are evenly distributed in the circumferential direction around the first adjustment plate 740.

[0051] When used specifically: install the first column 200 and the second column 300 on the base, adjust the adjustment device 700 using the top elevation value, and then install the beam 100. During installation, testing, or production, use the deflection pin 120 to achieve deflection of the beam 100 with the help of the deflection part 110 as needed. When secondary adjustment is required, turn the horizontal adjustment bolt 150 to achieve fine adjustment.

[0052] like Figure 3 As shown, in the present embodiment, the adjustment part 310 is two protruding plate-like bodies, the two adjustment parts 310 are symmetrically arranged on the side of the second column 300, the deflection part 110 is arranged in the middle of the two adjustment parts 310 in the form of a baffle, and adjustment bolts 320 are arranged on both sides of the two adjustment parts 310, so as to achieve the effect of adjustment and locking; of course, in other embodiments, the adjustment part 310 may also be a sleeve-shaped, spherical joint, etc.

[0053] like Figure 4 As shown, in this embodiment, the deflection pin 120 is fixed on the crossbeam 100. Of course, in some other embodiments, a pin hole 210 opposite to the first column 200 can be provided on the crossbeam 100, and inserted into the crossbeam 100 and the first column 200, respectively, to achieve the adjustment purpose of this embodiment. The inventors realize the lateral adjustment of the horizontal position of the crossbeam 100 by converting the hinge point into a deflectable pin on the basis of the simply supported beam structure.

[0054] The inventor adopts the most basic simply supported beam mechanism, installs deflection pin shafts 120 and deflection parts 110 on both sides of the cross beam 100, and arranges pin holes 210 and adjustment parts 310 which are matched with them on the two columns. The adjustment part 310 is provided with an adjustment bolt 320 which abuts against the deflection part 110 to realize the deflection adjustment of the cross beam 100; Horizontal adjustment bolts 150 are arranged at the bottom and top of the column to facilitate the adjustment of the cross beam 100 in the vertical direction. Through the above improvements, the space size of the gantry support structure can be finely adjusted to meet the detection accuracy or installation requirements.

[0055] Of course, in other embodiments, the adjusting device 700 can be omitted. Or the horizontal adjustment bolt 150 in the adjusting device 700 can be omitted.

[0056] Embodiment 2:

[0057] The main difference from Embodiment 1 lies in:

[0058] In this embodiment, the gantry support further includes: a vertical lifting mechanism, a measuring device, and a cast pipe support device.

[0059] The vertical lifting mechanism is movably arranged on the cross beam 100 and reciprocates along the length direction of the cross beam 100.

[0060] The measuring device is connected to the lifting end of the vertical lifting mechanism. The measuring device is used to measure the performance of the cast pipe. Generally, the performance of the cast pipe includes the performance of its own material and also the requirements for the appearance quality. In this embodiment, the measuring device is a thickness measuring device, mainly for detecting the wall thickness parameters of the cast pipe.

[0061] The cast pipe support device is located between the first column 200 and the second column 300. The cast pipe support device is used to place the cast pipe. The cast pipe is placed on the top surface of the cast pipe support device and is located below the cross beam 100. The axial length of the cast pipe is less than the distance between the second column 300 and the first column 200.

[0062] During detection, when the thickness measuring device moves rapidly along the surface of the cast pipe, if the generatrix on the surface of the cast pipe fluctuates up and down, the thickness measuring device can follow the up and down undulation of the generatrix to ensure that the thickness measuring device closely adheres to the surface of the cast pipe by gravity. The setting of the linear guide rail makes the thickness measuring device not swing back and forth.

[0063] During specific use: Install the first column 200 and the second column 300 on the base, adjust the adjusting device 700 by using the top elevation value, and then install the cross beam 100. During installation, detection, or production, according to the positional relationship between the measuring device and the cast pipe, use the deflection pin shaft 120 to realize the deflection of the cross beam 100 with the help of the deflection part 110. When secondary adjustment is required, turn the horizontal adjustment bolt 150 to realize fine adjustment.

[0064] The fine adjustment of the deflection of the cross beam 100 can be achieved through the adjustment part 310. Only manual screwing of the bolt is required to complete the corresponding work. The deflection adjustment around the single-sided column is achieved through the deflection pin shaft 120 of the cross beam 100, so that the cross beam 100 is parallel to the center line of the cast pipe, in order to adapt to the measurement device in the current production line to be able to match the axis of the cast pipe. The base adjustment device completes part of the horizontal adjustment of the cross beam 100, realizing the first fine adjustment of the horizontal adjustment. The horizontal adjustment bolt 150 realizes the second fine adjustment of the horizontal adjustment of the cross beam 100, that is, it meets the secondary fine adjustment during the adjustment in the installation process and the operation debugging of the detection mechanism.

[0065] Based on the above description of this specification, those skilled in the art can also understand the following terms used, such as the terms indicating the orientation or position relationship, such as "upper", "lower", "top", "bottom", "left", "right", "width", "length", etc. are based on the orientation or position relationship shown in the drawings of this specification. It is only for the purpose of facilitating the description of the solution of the present invention and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operate in the specific orientation. Therefore, the above terms of orientation or position relationship cannot be understood or interpreted as a limitation to the solution of the present invention.

[0066] In addition, in the description of this specification, the meaning of "a plurality" is at least two, such as two, three or more, etc., unless otherwise specifically defined.
