Gate pull rod system

Abstract

The gate pull rod system comprises an even number of pull rods which are connected end to end through pin shafts, each pull rod comprises two symmetrically-arranged pull rod plates and upper lifting lugs arranged at the tops of the pull rod plates, the upper lifting lugs are provided with upper lifting lug holes, and the bottoms of the pull rod plates are provided with lower lifting lug holes; the central axis of the upper lifting lug hole is perpendicular to the central axis of the lower lifting lug hole. The pin shaft in the pull rod system can be vertically installed, so that when the pull rod deflects due to external factors such as displacement of a locking beam and vibration of a gate or a trash rack, the pull rod connected with the pull rod can bear force perpendicular to the deflection direction, the friction force between the pin shaft and the hole wall of the pull rod is increased, and the pull rod is prevented from being damaged. Therefore, the influence effect of deflection of one section of the pull rod on the deflection amount of the whole pull rod is greatly reduced, the accident that the pin shaft is separated from the pull rod due to the fact that the pin shaft of the pull rod is stressed greatly and the fixed bolt is cut off is prevented, and the operation safety of the pull rod is effectively improved.

Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy facilities, and in particular relates to a gate pull rod system. Background Art

[0002] like Figure 1 As shown in the figure, the gate hoist uses the pull rod system as a traction component to realize the lifting and lowering control of the gate. The pull rod system includes multiple pull rods connected end to end. Figure 2 As shown, the top and bottom of the pull rod are provided with ear holes, and the central axes of these ear holes are parallel to the water flow direction. In this way, two problems will arise when connecting through a pin shaft:

[0003] 1. When one section of the tie rod deflects due to external factors such as displacement of the locking beam, vibration of the gate or trash rack, all the tie rods deflect in one direction, which will cause a large deflection of the entire tie rod. Sometimes, some pins may be sheared off the fixing bolts due to the large force, causing the pins to detach from the tie rods, resulting in losses, and subsequent inspection and maintenance will also be difficult.

[0004] 2. Conventionally, the locking beam and the pin are arranged vertically. The locking beam is locked along the direction of the water flow, and the pin is perpendicular to the direction of the water flow. Therefore, when loading and unloading the pin, there is a risk that the pin will fall into the gate hole. Summary of the invention

[0005] The object of the present invention is to provide a gate pull rod system, which changes the degree of deflection of the pull rod after being stressed and reduces the risk of the pull rod falling into the gate hole during disassembly.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a gate pull rod system, comprising an even number of pull rods connected end to end by a pin shaft, the pull rod comprising two symmetrically arranged pull rod plates and an upper lifting ear arranged on the top of the pull rod plate, the upper lifting ear is provided with an upper lifting ear hole, and the bottom of the pull rod plate is provided with a lower lifting ear hole; the central axis of the upper lifting ear hole is perpendicular to the central axis of the lower lifting ear hole.

[0007] Furthermore, the pull rod plate includes an upper vertical section, a lower vertical section and an inclined section, the inclined section is connected between the upper vertical section and the lower vertical section; the distance between the two upper vertical sections of the pull rod is greater than the distance between its two lower vertical sections, and the lower hanging ear hole is arranged on the lower vertical section.

[0008] Furthermore, the pull rod further comprises a rib plate, and the rib plate is arranged between two pull rod plates.

[0009] Furthermore, the pull rod also includes a lifting ear mounting plate, a connecting plate and connecting ribs, the lifting ear mounting plate is arranged on the top of the two pull rod plates, the upper lifting ear is arranged on the lifting ear mounting plate, the connecting plate is arranged between the two pull rod plates, and the connecting ribs are arranged between the lifting ear mounting plate and the connecting plate.

[0010] The present invention also provides a gate pull rod system, comprising an even number of pull rods connected end to end by a pin shaft, the pull rod comprising an upper connector and a lower connector telescopically connected; the top of the upper connector is provided with an upper lifting ear, the upper lifting ear is provided with an upper lifting ear hole, the lower connector comprises two symmetrically arranged pull rod plates, the bottom of the pull rod plates is provided with a lower lifting ear hole; the central axis of the upper lifting ear hole is perpendicular to the central axis of the lower lifting ear hole.

[0011] Furthermore, the pull rod plate includes an upper vertical section, a lower vertical section and an inclined section, the inclined section is connected between the upper vertical section and the lower vertical section; the distance between the two upper vertical sections of the pull rod is greater than the distance between its two lower vertical sections, and the lower hanging ear hole is arranged on the lower vertical section.

[0012] Further, the upper connector includes a lifting ear mounting plate and a screw rod, the upper lifting ear is arranged on the top surface of the lifting ear mounting plate, and two screw rods are arranged on the bottom surface of the lifting ear mounting plate;

[0013] The lower connecting body comprises a top plate, which is arranged on the top of the two tie rod plates and is provided with screw holes. The screws pass through the corresponding screw holes and are provided with adjusting nuts, and the adjusting nuts are located below the top plate.

[0014] Furthermore, the lower connecting body also includes an abutment plate, which is arranged between the two pull rod plates and is provided with an avoidance hole, the diameter of which is larger than the inner diameter of the adjusting nut; a locking nut and a pad located on the top of the locking nut are provided at the bottom of the screw, and a spring is provided on the screw between the pad and the abutment plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The pins in the tie rod system of the present invention can be installed in a manner that they are perpendicular to each other. Therefore, when the tie rod is deflected by external factors, such as displacement of the locking beam, vibration of the gate or the trash rack, the tie rod connected thereto will be subjected to a force perpendicular to the deflection direction, thereby increasing the friction between the pin and the wall of the tie rod hole and preventing deflection in the same direction. This greatly reduces the effect of the deflection of one section of the tie rod on the deflection of the entire tie rod, prevents the tie rod pin from shearing off the fixing bolt due to the large force, and prevents the pin from detaching from the tie rod, thereby effectively improving the safety of the tie rod operation.

[0017] 2. When disassembling the pull rod system of the present invention, only the pin shaft along the water flow direction needs to be disassembled. At this time, the pin shaft is more likely to fall onto the pier top above the gate hole instead of into the gate hole, thereby reducing the risk of falling.

[0018] 3. Since the pull rod system of the present invention has a pin shaft installed along the direction of water flow, it is easier to arrange a disassembly device on the pier top to replace manual disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0029] like Figures 3 to 5As shown, a gate tie rod system includes an even number of tie rods 100 connected end to end by a pin shaft 200. The tie rod 100 includes two symmetrically arranged tie rod plates 1 and an upper lifting ear 2 arranged on the top of the tie rod plate 1. The number of the upper lifting ears 2 is two, which are steel plates with a width of 160 mm, a height of 200 mm, and a thickness of 12 mm, and the spacing is 84 mm. The upper lifting ear 2 is provided with an upper lifting ear hole 2.1 for connecting the gate hoist 400 or the upper section of the tie rod 100. The bottom of the tie rod plate 1 is provided with a lower lifting ear hole 1.4 for connecting the gate lifting ear or the lower section of the tie rod 100. A reinforcing plate with a thickness of 16 mm and a diameter of 120 mm is provided at both the upper lifting ear hole 2.1 and the lower lifting ear hole 1.4, and the central axis of the upper lifting ear hole 2.1 is perpendicular to the central axis of the lower lifting ear hole 1.4.

[0030] As a preferred example, the tie rod plate 1 is a steel plate with a width of 160 mm, a length of 1542 mm, and a thickness of 12 mm, which includes an upper vertical section 1.1, a lower vertical section 1.3, and an inclined section 1.2. The length of the upper vertical section 1.1 is 982.5 mm, and the length of the inclined section 1.2 is 360 mm. The inclined section 1.2 is connected between the upper vertical section 1.1 and the lower vertical section 1.3; the distance between the two upper vertical sections 1.1 of the tie rod 100 is 84 mm, and the distance between the two lower vertical sections 1.3 is 24 mm, and the lower hanging ear hole 1.4 is set on the lower vertical section 1.3. The apertures of the upper hanging ear hole 2.1 and the lower hanging ear hole 1.4 are both 60 mm.

[0031] As a preferred example, the tie rod 100 further includes a rib plate 3. The rib plate 3 is arranged between two tie rod plates 1. The rib plate 3 is a steel plate member with a length of 1060 mm and a thickness of 12 mm, and the distance between the top of the rib plate 3 and the top of the tie rod plate 1 is 332 mm.

[0032] As a preferred example, the tie rod 100 also includes a lifting ear mounting plate 4, a connecting plate 5 and a connecting rib 6. The lifting ear mounting plate 4 is a steel plate member with a length of 160 mm, a width of 160 mm and a thickness of 16 mm, which is arranged on the top of the two tie rod plates 1, and the upper lifting ear 2 is arranged on the lifting ear mounting plate 4. The connecting plate 5 is a steel plate member with a length of 160 mm, a width of 84 mm and a thickness of 12 mm, which is arranged between the two tie rod plates 1. The connecting rib 6 is a steel plate member with a height of 120 mm, a width of 38 mm and a thickness of 20 mm, two of which are provided and connected between the lifting ear mounting plate 4 and the connecting plate 5.

[0033] like Figure 6 and 9As shown, all the tie rods 100 are connected end to end, and the connecting piece is a pin 200, wherein the top section of the tie rod 100 is connected to the lifting lug of the gate opening machine 400 through the pin 200, and the bottom section of the tie rod 100 is connected to the lifting lug of the gate through the pin 200. In this way, the axis of some of the pins 200 is parallel to the direction of water flow, and only this part of the pins 200 needs to be removed during disassembly, and these pins 200 will fall directly to the top of the pier, avoiding the risk of falling into the gate hole. After removing the pins 200, the tie rods 100 are removed in groups of two and stored, reducing the number of disassembly.

[0034] It should be noted that a disassembly device 300 can be set on the pier top. The disassembly device 300 includes a hydraulic cylinder and a push rod. The push rod is driven by the hydraulic cylinder to move in a direction parallel to the water flow. In this way, the pin shaft 200 to be disassembled can be aligned and pushed out by mechanical force, which is more efficient and labor-saving than manual disassembly. Example

[0035] like Figures 6 to 8 As shown, the difference between this embodiment and the first embodiment is that the pull rod 100 includes an upper connector and a lower connector that are telescopically connected. An upper lifting ear 2 is provided on the top of the upper connector, and an upper lifting ear hole 2.1 is provided on the upper lifting ear 2. The lower connector includes two symmetrically arranged pull rod plates 1, and a lower lifting ear hole 1.4 is provided on the bottom of the pull rod plate 1. The central axis of the upper lifting ear hole 2.1 is perpendicular to the central axis of the lower lifting ear hole 1.4. Due to the telescopic function of the upper connector and the lower connector, the center distance between the upper lifting ear hole 2.1 and the lower lifting ear hole 1.4 varies from 1300mm to 2000mm.

[0036] In this example, the length of the tie rod plate 1 is 1159.5 mm, the length of the upper vertical section 1.1 is 600 mm, and the length of the inclined section 1.2 is 360 mm.

[0037] As a preferred example, the upper connector includes a lifting ear mounting plate 4 and a screw 8. The upper lifting ear 2 is arranged on the top surface of the lifting ear mounting plate 4, and the screw 8 has a nominal diameter of 24 mm and a length of 800 mm, and is provided with two screws, and is arranged on the bottom surface of the lifting ear mounting plate 4 with a center distance of 88 mm.

[0038] The lower connector includes a top plate 7, which is a steel plate with a width of 84 mm, a length of 160 mm, and a thickness of 16 mm. The top plate 7 is arranged on the top of the two tie rod plates 1 and is provided with a screw hole with a diameter of 30 mm. The screw 8 passes through the corresponding screw hole and is provided with an adjusting nut 12, which is located below the top plate 7. By changing the position of the adjusting nut 12 on the screw 8, the telescopic length between the upper connector and the lower connector can be adjusted.

[0039] As a preferred example, the lower connector also includes an abutment plate 9, which is a steel plate with a width of 84 mm, a length of 160 mm, and a thickness of 12 mm. The abutment plate 9 is arranged between the two tie rod plates 1 and is provided with an avoidance hole with a diameter of 50 mm. The avoidance hole is used to avoid the adjustment nut 12 so that it can pass through. The bottom of the screw rod 8 is provided with a locking nut 11 and a pad 13 located on the top of the locking nut 11. The pad 13 is a steel plate with a diameter of 72 mm and a thickness of 12 mm. A spring 10 is sleeved on the screw rod 8 between the pad 13 and the abutment plate 9. In this example, since the tie rod 100 can be telescopic, the number of the tie rods 100 can be better determined according to the lifting distance, and after the tie rod 100 is removed, under the action of the spring 10, the upper connector and the lower connector are in the minimum telescopic state, so that the overall length of the tie rod 100 becomes the minimum, which is more convenient for transportation and storage.

[0040] The matters not described in detail in the present invention are all known technologies to those skilled in the art.

[0041] It should be noted that the above specific implementation methods are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified and replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
