Description

Technical Field

[0001] The utility model relates to the technical field of steel structure correction, in particular to a correction device for a chute casing concrete supporting steel liner. Background Art

[0002] In order to extend the service life of the chute, reduce the degree of friction deformation of the chute, and reduce the number of chute repairs, the chute is usually supported by a combination of concrete and steel lining. However, the steel lining is easily deformed during transportation and lowering, resulting in problems such as poor docking when welding the steel lining, poor welding forming effect, and welding misalignment. This not only increases the difficulty of construction, but also often fails to meet the quality standards. In order to effectively correct the steel lining, the chute needs to be supported by a concrete steel lining correction device for correction.

[0003] However, the existing correction devices are usually correction flat plates or fixed arc plates, which cannot be corrected according to the deformation of the steel liner at the construction site. This makes it impossible to use the existing correction devices to correct the deformation of the concrete support steel liner of the chute. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1-3 A device for correcting a steel liner of a concrete support for a chute comprises a workbench body 1. A plurality of first correction rollers 7 are arranged above the workbench body 1. The first correction rollers 7 are connected to a hydraulic jack 2. The first correction rollers 7 are connected to a first correction roller shaft 8 and a hydraulic jack push rod 9 through a bearing 10. A hydraulic oil tank 3, a hydraulic oil pump 4 and a hydraulic controller 11 are arranged below the workbench body 1. The hydraulic oil pump 4 supplies oil to the hydraulic jack 2 through the hydraulic controller 11, and controls the hydraulic jack push rod 9 to move forward and backward through a hydraulic switch 12 arranged on the hydraulic controller 11.

[0018] A second correction roller 5 and a plurality of third correction rollers 17 located on both sides of the second correction roller 5 are also arranged above the workbench body 1. The second correction roller 5 and the third correction roller 17 are arranged on the opposite side of the first correction roller 7 and correspond to the first correction roller 7. The third correction roller 17 is connected to a push rocker 18, which is connected to the third correction roller 17 through a rotating buckle 20. The push rocker 18 is provided with a thread. The push rocker 18 passes through the workbench body 1 and is connected with a threaded hole reserved on the workbench body 1. By rotating the handle 19, the push rocker 18 drives the third correction roller 17 to move forward and backward. A guide groove is arranged below the first correction roller 7, the second correction roller 5, and the third correction roller 17, and the first correction roller shaft 8 can move in the guide groove.

[0019] The second correction roller 5 is connected to the driving motor 13, and the driving motor 13 is provided with a first pulley 14, and the first pulley 14 is connected to the second pulley 16 provided on the second correction roller shaft 6 through a belt 15.
