[0001] The utility model relates to the technical field of hydraulic plane steel gate shaft hole construction, in particular to a plane steel gate inter-section connection shaft hole inspection device. Background Art

[0002] Traditional flat-surface gate manufacturing is typically done in multiple sections, requiring on-site assembly. The gate's inter-section connecting plates require a final inspection after assembly to ensure the dimensions of the inter-section connecting shaft holes meet specifications. This requires high precision control of the spacing between the two shaft holes of the inter-section connecting lugs and the inclination of the shaft holes. After processing, a pre-assembly inspection of the connecting shaft, connecting plate, and inter-section connecting lugs is required. Because the inter-section connecting shaft and connecting plate weigh approximately 300 kilograms each, the connecting shaft cannot be hoisted after assembly, making assembly inspection impossible.

[0003] Therefore, it is necessary to develop a planar steel gate inter-section connection shaft hole inspection device to solve the above problems. Utility Model Content

[0029] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-6 As shown, a device for inspecting the axis holes of the inter-section connection of a flat steel gate comprises:

[0031] A wheelbase measuring device 2 for measuring the wheelbase between two intersegment coupling shaft holes 102; the wheelbase measuring device 2 includes two inspection cylinders 201 and a steel plate. The steel plate is formed into an elliptical plate-like structure. The side walls of the two inspection cylinders 201 are connected by the steel plate. The two inspection cylinders 201 are parallel to each other and are arranged at the same height. The outer diameter of the inspection cylinders 201 is the same as the inner diameter of the intersegment coupling shaft hole 102. The distance between the two inspection cylinders 201 is equal to the distance between the two intersegment coupling shaft holes 102.

[0032] A center measuring device 3 for checking the center deviation size of the intersegment connecting shaft hole 102; the center measuring device 3 includes two positioning devices and a steel wire 304, the two ends of the first positioning device are respectively connected to the first sides of the two door leaves 1, and the two ends of the second positioning device are respectively connected to the second sides of the two door leaves 1, the steel wire 304 is inserted from the assembly gap between the two door leaves 1, and the two ends of the steel wire 304 are respectively connected to the two positioning devices, the distance between the steel wire 304 and the two door leaves 1 is the same, and the distance from the center point of the two door leaves 1 to the central axis of the intersegment connecting shaft hole 102 on the two door leaves 1 is the same.

[0033] In some embodiments, as Figure 1-3 As shown, the positioning device includes an outer transverse plate 301 and two inner transverse plates 302. The inner transverse plate 302 is radially installed in the side shaft wheel hole 103 of the door leaf 1, and the outer transverse plate 301 is installed outside the side shaft wheel hole 103. The outer transverse plate 301 is parallel to the inner transverse plate 302. The outer transverse plate 301 is respectively connected to the two inner transverse plates 302. The two ends of the steel wire 304 are respectively connected to the outer transverse plates 301 of the two positioning devices, and the connection is located at the center of the assembly gap between the two door leaves 1.

[0034] In some embodiments, as Figure 1-3As shown, screw holes are provided on the inner transverse plate 302 and the outer transverse plate 301 , and the inner transverse plate 302 and the outer transverse plate 301 are connected by fastening bolts 303 passing through the screw holes on the inner transverse plate 302 and the outer transverse plate 301 .

[0035] In some embodiments, as Figure 4 As shown, one side of the steel plate is provided with multiple reinforcing ribs 202. The two inspection cylinders 201, the steel plate, and the reinforcing ribs 202 are welded together as a single unit. In special cases involving bilateral intersegmental connection holes 102 (where the distance between individual components is greater than 1m), the inspection cylinder 201 can be designed as a separate hollow cylinder for standalone use. During inspection, the inspection cylinder 201 is first inserted into the pre-machined intersegmental connection holes 102, followed by a socketed inspection of the steel plate and the inspection cylinder 201 (two slots are pre-set on the steel plate for inserting the inspection cylinder 201). The steel plate is 6mm thick and cut into its entirety. The reinforcing ribs 202 can be made of standard Q345 steel, with a thickness of 4-6mm and a width of 50mm. They are intermittently welded to the wheelbase measuring device 2, with a weld height of no less than 6mm.

[0036] In some embodiments, as Figure 6 As shown, the height of the inspection cylinder 201 is 100 mm greater than the depth of the intersegmental connecting shaft hole 102, which facilitates observation of dimensional deviation.

[0037] The quality inspection of the inter-segment coupling shaft holes 102 in this application utilizes two methods: a wheelbase measuring device 2 and a center measuring device 3 to verify the machining quality. After the door leaf panel 101 is assembled, two inter-segment coupling shaft holes 102 are formed. After simple boring machining, an inspection cylinder 201 is inserted into the inter-segment coupling shaft holes 102 for measurement.

[0038] like Figure 1 As shown, the middle inter-section connecting shaft hole 102 of the door leaf 1 should be bored after the door leaf panel 101 is welded and assembled as a whole, and the other dimensions are qualified.

[0039] Check that the raw material of the cylinder 201 before processing should be about 20 mm larger than the designed diameter of the inter-segment connecting shaft hole 102 to reserve a processing allowance.

[0040] After the intersegmental connection shaft hole 102 is bored, the wheelbase measuring device 2 is first used to insert the inspection cylinders 201 at both ends into the intersegmental connection shaft hole 102. If it can be inserted into the intersegmental connection shaft hole 102 smoothly and there is no jamming in the shaft holes on both sides, it is considered unqualified. Otherwise, it is judged as unqualified.

[0041] After passing the inspection of the wheelbase measuring device 2, the inner and outer sides of the side wheel hole 103 of the door leaf 1 are respectively installed with the inner transverse plate 302 and the outer transverse plate 301 and fixed with the fastening bolts 303.

[0042] The door leaf 1 is set on both sides respectively. The size of the shaft wheel hole 103 on the side of the processed door leaf 1 is first measured with a theodolite or a steel ruler on the outside, and the center size is measured. The size is recorded at the upper end of the outer cross plate 301 of the installed center measuring device 3, and the distance from the center size of the door leaf 1 is calculated and a clear scale is sawed on the center position of the two sections of the door leaf 1 for tying the measuring steel wire 304.

[0043] The personnel enter from the assembly gap of door leaf 1, arrange 0.2mm steel wire 304 at the center position of the assembly internode of door leaf 1, remove the wheelbase measuring device 2, and measure the steel wire 304 next to the internode connecting shaft hole 102 with a steel ruler to obtain the absolute size deviation of the shaft hole.

[0044] Subsequent construction can only be carried out after each shaft hole has passed the above two inspections.

[0045] The construction method of the present invention comprises:

[0046] The two door leaves 1 are hoisted and assembled in a horizontal manner using a lifting device, and the specific position of the door leaf 1 is adjusted, and key parts such as the door leaf panel 101, the inter-section connecting shaft hole 102 and the side shaft wheel hole 103 are adjusted into place.

[0047] Install the prefabricated shaft hole measuring device and center measuring device 3 and their accessories. Install the outer cross plate 301 and inner cross plate 302 from the inside and outside of the side shaft wheel hole 103 on the center measuring device 3 and secure them to the side shaft wheel hole 103 with fastening bolts 303. Locate the exact size from the center of the side shaft wheel hole 103 of the door leaf 1, calculate the size to the center size of the door leaf 1 internode, lay out 0.2mm steel wire 304, and tie it to the outer cross plate 301 at the center measuring device 3 on both sides of the door leaf 1 to mark the position.

[0048] The steel wire 304 of the center measuring device 3 is used to check the positioning point of the intersegmental connecting shaft hole 102 to be processed. After the size is qualified, the intersegmental connecting shaft hole 102 is processed and the axis hole measuring device is used to check the wheelbase size of the intersegmental connecting shaft hole 102.

[0049] After completing the above inspection, use a flat measuring steel ruler to approach the intersegmental connecting shaft hole 102, parallel to the outside of the steel wire 304 close to the center measuring device 3, take the outside of the steel wire 304 as the measurement zero point coordinate, close to the outside of the intersegmental connecting shaft hole 102, and measure the shaft holes on both sides of the steel wire 304 symmetrically, read the actual values, and obtain the absolute size values ​​of the intersegmental connecting shaft holes 102 on both sides, and check the center deviation dimensions on both sides of the intersegmental connecting shaft hole 102 to meet the design size requirements.

[0050] Through the inspection of the above two methods, the machining accuracy of the inter-segment connection shaft hole 102 of the gate leaf 1 is verified, which perfectly solves the disadvantages of the inspection by a single method and ensures the machining quality of the inter-segment shaft hole of the plane gate.

[0051] Through construction practice, the use of the axis hole measuring device and the center measuring device 3 solved the problem that the narrow space of the hydraulic plane steel gate inter-section connection axis hole 102 was difficult to install the connecting shaft with the help of lifting machinery and equipment, thereby minimizing the labor intensity of construction technicians.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
