Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steel moving devices, and in particular relates to a steel moving device which can prevent a lifting mechanism from accidentally falling. Background Art
[0002] The bar production line generally uses a walking cooling bed. After the bar is cooled by the cooling bed, the bar is aligned by the alignment roller, and then moved out of the alignment roller and laid flat on the steel transfer chain. The steel transfer chain rotates to move several finished bars to the top of the steel transfer device. The lifting device in the steel transfer device moves several bars to the cold output roller through two actions of lifting and pulling back, preparing for the next step of cold shearing.
[0003] Usually, when a lifting device is repaired, damaged or replaced, it is necessary to extend the lifting device to the highest position. At this time, the lifting device is in a lifted state and there is generally a risk of it falling due to a lack of measures to prevent the lifting device from accidentally falling. This is an unstable state during the maintenance process and there are certain safety risks. If an accident occurs, the lifting device may fall, resulting in casualties. Therefore, it is particularly important to prevent the lifting device from accidentally falling during the maintenance process. Utility Model Content
[0004] The utility model aims to provide a steel moving device which can prevent a lifting mechanism from accidentally falling, so as to solve the problem of potential safety hazards caused by the lifting device accidentally falling in a lifted state.
[0005] The technical solution of the utility model is: a steel moving device for preventing a lifting mechanism from accidentally falling, comprising a lifting mechanism connecting rod, a steel supporting arm base and a steel moving device beam, a hydraulic cylinder barrel is connected to the bottom of the steel moving device beam, a hydraulic cylinder rod on the hydraulic cylinder barrel, an end of the steel moving device beam and the steel supporting arm base are movably connected respectively through the lifting mechanism connecting rod, two semi-annular clamping tubes are provided along the length direction of the hydraulic cylinder rod, connecting pieces are provided at both ends of the clamping tube opening, and the two connecting pieces are connected by bolts.
[0006] As a further improvement of the utility model, a protective pad is provided on the inner wall of the clamping tube.
[0007] The beneficial effects of the utility model are as follows: the hydraulic cylinder rod is fully extended so that the lifting mechanism connecting rod drives the supporting steel arm base to be in a lifted state. At this time, the two clamping tubes are installed and connected to the hydraulic cylinder rod, which effectively prevents the hydraulic cylinder rod from accidentally moving and causing retraction, eliminates the safety risks caused by accidental falling of the lifting device, greatly reduces the possibility of injury to maintenance and construction personnel, and ensures that personnel and operations are in a safe and stable operating state.
[0008] The utility model can effectively eliminate the safety risk caused by the accidental falling of the lifting device, can complete the disassembly and assembly in a short time during daily maintenance, and is simple, convenient, flexible and effective to use. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a schematic diagram of the overall structure of the utility model;
[0010] Figure 2 It is a side view of the clamping pipe structure in the utility model.
[0011] In the figure: 1-hydraulic cylinder barrel; 2-hydraulic cylinder rod; 3-clamp pipe; 31-connecting piece; 32-protection pad; 4-lifting mechanism connecting rod; 5-steel support arm base; 6-steel moving device beam; 7-bolt. DETAILED DESCRIPTION
[0012] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0013] like Figure 1-Figure 2 As shown, a steel-moving device for preventing a lifting mechanism from accidentally falling comprises a lifting mechanism connecting rod 4, a steel-supporting arm base 5 and a steel-moving device beam 6. A hydraulic cylinder barrel 1 is hinged at the bottom of the steel-moving device beam 6. A hydraulic cylinder rod 2 on the hydraulic cylinder barrel 1 and the end of the steel-moving device beam 6 are movably connected to the steel-supporting arm base 5 respectively through the lifting mechanism connecting rod 4. The hydraulic cylinder rod 2 is provided with two semi-annular clamping tubes 3 along its length direction. Connecting pieces 31 are provided at both ends of the opening of the clamping tube 3. The two connecting pieces 31 are connected by bolts 7. A protective pad 32 is provided on the inner wall of the clamping tube 3.
[0014] When the lifting device in the steel moving device needs to be inspected and repaired, the device is first shut down as a whole, and the hydraulic cylinder rod 2 is fully extended. At this time, the lifting mechanism connecting rod 4 drives the steel supporting arm base 5 to rise to a high position, and two clamping tubes 3 with an inner diameter slightly larger than the diameter of the hydraulic cylinder rod 2 are clamped on the hydraulic cylinder rod 2. The connecting pieces 31 on the two clamping tubes 3 are connected and clamped with bolts 7. The split clamping tube 3 formed by the two semi-annular clamping tubes 3 has the advantages of easy access, simple installation, safety and effectiveness. The protective pad 32 on the inner wall of the clamping tube 3 can prevent the hydraulic cylinder rod 2 from being worn, will not cause damage to the components, and ensure normal operation.
[0015] After the clamping tube 3 is installed, the lifting device in the lifted state can be inspected and replaced. During this operation, even if the hydraulic cylinder rod 2 accidentally retracts, the hydraulic cylinder rod 2 cannot be completely retracted into the hydraulic cylinder barrel 1 due to the setting of the clamping tube 3, which effectively ensures the safety of the operation. After the inspection is completed, the two clamping tubes 3 are removed, and the steel moving device and the lifting device work normally, which saves inspection time. It is simple, convenient, flexible and effective to use.
