Description

Technical Field

[0001] The utility model relates to the field of steel grating production equipment, in particular to a fixing device for steel grating welding. Background Art

[0002] Steel grating plate is also called steel grating. The grating plate is made of flat steel that is cross-arranged at a certain interval and cross bars and welded into a steel product with a square grid in the middle. It is mainly used for ditch covers, steel structure platform plates, steel ladder treads, etc. The cross bars are generally made of twisted square steel. Steel grating plates are generally made of carbon steel, and the surface is hot-dip galvanized to prevent oxidation. It can also be made of stainless steel. Steel grating plates have ventilation, lighting, heat dissipation, anti-slip, explosion-proof and other properties.

[0003] When producing steel gratings, both ends of the steel gratings need to be edge-welded. When performing edge welding, the steel gratings need to be placed on a special fixing fixture to fix their position for easy operation. However, the fixing device for welding steel gratings in the existing technical solutions is difficult to adjust due to its simple structure. This results in the fixing device being unable to fix steel gratings of different specifications and sizes, which in turn limits the use of the fixing device. Utility Model Content

[0012] A further technical solution is that the first fixing member and the second fixing member are both bolts.

[0013] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0014] 1. Due to the use of the base, support plate, buffer device, abutment device, lifting device and connection plate, when the steel grating needs to be fixed, first place the steel grating on the support plate, and make one side of the steel grating abut against the buffer device. Then the staff adjusts the abutment device to move the abutment device toward the other side of the steel grating and make the abutment device abut against the other side of the steel grating. By abutting the abutment device against the other side of the steel grating and moving a certain distance again, the steel grating can generate a certain extrusion force on the buffer device and compress the buffer device. At this time, the buffer device will generate a reaction force on the steel grating, so that the steel grating can be firmly fixed between the buffer device and the abutment device. Since the spacing between the buffer device and the abutment device can be adjusted according to the adjustment of the abutment device, steel gratings of different specifications and sizes can be fixed between the buffer device and the abutment device. Since the lifting device works through the sliding end, it can drive the support plate to move up and down, and then the height of the steel grating fixed between the buffer device and the abutment device can be adjusted, so to a certain extent, the practicality of the fixing device is greatly improved. Due to the arrangement of the first bending plate, the first fixing member, the first baffle, the first threaded rod, the first telescopic rod and the first spring, and because the first fixing member passes through the first bending plate and is threadedly connected to the support plate, it is convenient for the staff to disassemble and replace the abutting device. Since the end of the first threaded rod abuts against the first baffle, the staff can make the end of the first threaded rod push the first baffle to move by rotating and tightening the first threaded rod. During the process of the first threaded rod end pushing the first baffle to move, the telescopic end of the first telescopic rod 45 will be extended, and the first spring will be in a stretched state. Since the first spring is in an elongated state, the first baffle can always abut against the end of the first threaded rod during the movement. When it is necessary to make the first baffle in the abutting device abut against the other side of the steel grating, the staff only needs to rotate and tighten the first threaded rod to move the first baffle to the other side of the steel grating and firmly abut against the steel grating. The whole operation process is simple and reliable, which is convenient for the staff to operate.

[0015] 2. Due to the arrangement of the second baffle, the second spring, the second telescopic rod and the support block, when the abutting device abuts against the other side of the steel grating and moves a certain distance again, the steel grating can generate a certain extrusion force on the second baffle in the buffer device. The second baffle subjected to the extrusion force will compress the second spring and the second telescopic rod. At this time, the second spring in the compressed state will generate a reaction force, thereby enabling the second baffle to abut firmly against the steel grating. When the second spring is in the compressed state, the second telescopic rod will prevent the second spring from deforming, thereby providing a certain protection for the second spring.

[0016] 3. Due to the arrangement of the second bending plate, the second fixing member, the slider, the second threaded rod, the limiting slide rail and the bearing seat, and the second fixing member passing through the second bending plate and being threadedly connected to the support plate, it is convenient for the staff to disassemble and repair the support plate installed on the lifting device. Since the slider is threadedly connected to the second threaded rod, and both ends of the slider are slidably connected to the two sets of limiting slide rails, the slider can be driven to slide up and down along the two sets of limiting slide rails by rotating the second threaded rod, thereby adjusting the height of the support plate.

[0017] 4. Due to the setting of the bending handle, the first threaded rod can be driven to rotate together by rotating the bending handle, thereby making it more convenient for the staff to operate.

[0018] 5. Due to the setting of the threaded handle, the second threaded rod can be driven to rotate together by rotating the threaded handle, which makes it more convenient for the staff to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The embodiment of the present application provides a fixing device for welding steel gratings, thereby solving the technical problem that the fixing device for welding steel gratings in the prior art solution has a relatively simple structure and is difficult to adjust, which results in the fixing device being unable to fix steel gratings of different specifications and sizes, thereby causing the fixing device to be limited in use.

[0026] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] A fixing device for welding a steel grating, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a base 1, a support plate 2 for supporting a steel grating, a buffer device 3 for abutting against the steel grating, a abutting device 4 for clamping and fixing the steel grating, a lifting device 5 for driving the support plate 2 to rise and fall, and a connecting plate 6 for supporting the lifting device 5. The connecting plate 6 is arranged on the base 1. The buffer device 3 and the abutting device 4 are both arranged on the support plate 2. The support plate 2 is arranged on the sliding block of the lifting device 5. The lifting device 5 is arranged on the connecting plate 6.

[0029] The abutting device 4 includes a first bending plate 41, a first fixing member 42 for fixing the first bending plate 41, a first baffle 43 for abutting against the steel grating, a first threaded rod 44 for pushing the first baffle 43 to move, a first telescopic rod 45 for supporting the first baffle 43, and a first spring 46 arranged around the first telescopic rod 45. The first fixing member 42 is connected to the first bending plate 41 and the support plate 2. The first threaded rod 44 is threadedly connected to the first bending plate 41, and one end of the first threaded rod 44 abuts against the first baffle 43. Two groups of first telescopic rods 45 are arranged on the first bending plate 41, and the two groups of first telescopic rods 45 are symmetrically placed with the first threaded rod 44. The telescopic ends of the two groups of first telescopic rods 45 are both connected to the first baffle 43. One end of the first spring 46 is connected to the first bending plate 41, and the other end of the first spring 46 is connected to the first baffle 43.

[0030] The connecting plate 6 is fixedly connected to the base 1. The buffer device 3 and the abutting device 4 are both fixedly connected to the top of the support plate 2. By adjusting the abutting device 4, the distance between the buffer device 3 and the abutting device 4 can be adjusted. The support plate 2 is fixedly connected to the sliding block of the lifting device 5. The lifting device 5 is fixedly connected to the connecting plate 6.

[0031] The bottom end of the first bending plate 41 is provided with a plurality of groups of first fixing members 42 arranged in a linear array. The first fixing members 42 are preferably bolts. Each group of first fixing members 42 passes through the first bending plate 41 and is threadedly connected to the support plate 2. The telescopic ends of the two groups of first telescopic rods 45 are fixedly connected to the first baffle plate 43. The other ends of the two groups of first telescopic rods 45 are fixedly connected to the first bending plate 41. The outsides of the two groups of first telescopic rods 45 are surrounded by first springs 46. One end of the two groups of first springs 46 is fixedly connected to the first bending plate 41, and the other ends of the two groups of first springs 46 are fixedly connected to the first baffle plate 43.

[0032] Due to the arrangement of the base 1, the support plate 2, the buffer device 3, the abutment device 4, the lifting device 5 and the connecting plate 6, when the steel grating needs to be fixed, the steel grating is first placed on the support plate 2, and one side of the steel grating is abutted against the buffer device 3. Then the staff adjusts the abutment device 4 to move the abutment device 4 toward the other side of the steel grating and abut the abutment device 4 against the other side of the steel grating. By abutting the abutment device 4 against the other side of the steel grating and moving a certain distance again, the steel grating can generate a certain extrusion force on the buffer device 3 and compress the buffer device 3. At this time, the buffer device 3 will generate a reaction force on the steel grating, and then the steel grating can be firmly fixed between the buffer device 3 and the abutment device 4. Since the spacing between the buffer device 3 and the abutment device 4 can be adjusted according to the adjustment of the abutment device 4, steel gratings of different specifications and sizes can be fixed between the buffer device 3 and the abutment device 4. Since the lifting device 5 works through the sliding end, the support plate 2 can be driven to move up and down, and then the steel grating fixed between the buffer device 3 and the abutment device 4 can be adjusted in height, so the practicality of the fixing device is greatly improved to a certain extent. Due to the arrangement of the first bending plate 41, the first fixing member 42, the first baffle 43, the first threaded rod 44, the first telescopic rod 45 and the first spring 46, since the first fixing member 42 passes through the first bending plate 41 and is threadedly connected to the support plate 2, it is convenient for the staff to disassemble and replace the abutment device 4. Since the end of the first threaded rod 44 abuts against the first baffle 43, the staff can make the end of the first threaded rod 44 push the first baffle 43 to move by rotating and tightening the first threaded rod 44. In the process of pushing the first baffle 43 to move, the end of the first telescopic rod 45 will be extended, and the first spring 46 will be in a stretched state. Since the first spring 46 is in an elongated state, the first baffle 43 can always be against the end of the first threaded rod 44 during the movement. When it is necessary to make the first baffle 43 in the abutting device 4 abut against the other side of the steel grating, the staff only needs to rotate and tighten the first threaded rod 44 to move the first baffle 43 to the other side of the steel grating and firmly abut against the steel grating. The whole operation process is simple and reliable, which is convenient for the staff to operate.

[0033] like Figure 4 As shown, the buffer device 3 includes a second baffle 31 for abutting against the steel grating, a second spring 32 for buffering the second baffle 31, a second telescopic rod 33 for limiting the second spring 32, and a support block 34 arranged on the support plate 2. The second spring 32 surrounds the second telescopic rod 33. The telescopic end of the second telescopic rod 33 is connected to the second baffle 31. The other end of the second telescopic rod 33 is connected to the support block 34.

[0034] The support block 34 is fixedly connected to the top of the support plate 2. Three groups of second telescopic rods 33 arranged in a linear array are fixedly connected to the support block 34. The other end of each group of second telescopic rods 33 is fixedly connected to the second baffle 31. A second spring 32 is arranged around the outside of each group of second telescopic rods. One end of each group of second springs 32 is fixedly connected to the support block 34. The other end of each group of second springs 32 is fixedly connected to the second baffle 31.

[0035] Due to the arrangement of the second baffle 31, the second spring 32, the second telescopic rod 33 and the support block 34, when the abutting device 4 abuts against the other side of the steel grating and moves a certain distance again, the steel grating can generate a certain extrusion force on the second baffle 31 in the buffer device 3, and the second baffle 31 subjected to the extrusion force will compress the second spring 32 and the second telescopic rod 33. At this time, the second spring 32 in the compressed state will generate a reaction force, thereby enabling the second baffle 31 to be firmly abutted against the steel grating. When the second spring 32 is in the compressed state, the second telescopic rod 33 will prevent the second spring 32 from being deformed, thereby providing a certain protection for the second spring 32.

[0036] like Figure 5 As shown, the lifting device 5 includes a second bending plate 51, a second fixing member 52 for fixing the second bending plate 51, a slider 53 for driving the second bending plate 51 to rise and fall, a second threaded rod 54 for driving the slider 53 to move, a limiting slide rail 55 for limiting the sliding movement of the slider 53, and a bearing seat 56 arranged on the connecting plate 6. The second fixing member 52 is connected to the second bending plate 51 and the supporting plate 2. The second bending plate 51 is arranged on the slider 53. The slider 53 is threadedly connected to the second threaded rod 54. Two groups of limiting slide rails 55 symmetrically arranged with the second threaded rod 54 are arranged on the connecting plate 6. The two ends of the slider 53 are respectively slidably connected to the two groups of limiting slide rails 55. The two ends of the second threaded rod 54 are respectively arranged on the inner rings of the bearings in the two groups of bearing seats 56.

[0037] The second fixing member 52 is preferably a bolt. The second fixing member 52 passes through the second bent plate 51 and is threadedly connected to the support plate 2. The second bent plate 51 is fixedly connected to the slider 53. Two groups of limit slide rails 55 symmetrically arranged with the second threaded rod 54 are fixedly connected to the connecting plate 6. Two groups of bearing seats 56 symmetrically arranged with the center of the second threaded rod 54 are fixedly connected to the connecting plate 6. The two ends of the second threaded rod 54 are respectively fixedly connected to the inner rings of the bearings in the two groups of bearing seats 56.

[0038] Due to the arrangement of the second bending plate 51, the second fixing member 52, the slider 53, the second threaded rod 54, the limiting slide rail 55 and the bearing seat 56, and because the second fixing member 52 passes through the second bending plate 51 and is threadedly connected to the support plate 2, it is convenient for the staff to disassemble and repair the support plate 2 installed on the lifting device 5. Since the slider 53 is threadedly connected to the second threaded rod 54, and both ends of the slider 53 are slidably connected to the two sets of limiting slide rails 55, the slider 53 can be driven to slide up and down along the two sets of limiting slide rails 55 by rotating the second threaded rod 54, so that the height of the support plate 2 can be adjusted.

[0039] like Figure 2 As shown, the abutment device 4 further includes a bending handle 47. The bending handle 47 is arranged at the other end of the first threaded rod 44.

[0040] The bending handle 47 is fixedly connected to the other end of the first threaded rod 44 .

[0041] Since the bending handle 47 is provided, the first threaded rod 44 can be driven to rotate together by rotating the bending handle 47, thereby making it more convenient for the staff to operate.

[0042] like Figure 5 As shown, the lifting device 5 further includes a threaded handle 57. The threaded handle 57 is arranged at the top end of the second threaded rod 54.

[0043] The threaded handle 57 is fixedly connected to the top end of the second threaded rod 54 .

[0044] Due to the provision of the threaded handle 57, the second threaded rod 54 can be driven to rotate together by rotating the threaded handle 57, thereby making it more convenient for the staff to operate.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.
