Description

Technical Field

[0001] This utility model relates to the technical field of shot blasting hangers for spherical crown liners of railway bridge bearings, and particularly to shot blasting hangers for spherical crown liners of railway bridge bearings. Background Technology

[0002] Shot blasting is a common metal surface treatment process, mainly used to clean impurities such as oxide scale, rust, oil, and dirt from metal surfaces, while improving the strength and corrosion resistance of the metal surface. The basic principle of shot blasting is to use a high-speed rotating shot blasting machine to impact the metal surface with granular materials such as steel shot at high speed, thereby achieving the effect of cleaning and strengthening the surface. Shot blasting racks are auxiliary equipment specifically designed for shot blasting cleaning processes, mainly used to fix and hang the workpieces to be treated, and are quite common in shot blasting operations.

[0003] Existing technologies, such as the utility model patent with publication number CN203650279U, disclose a shot blasting machine hanger. This hanger consists of a chassis, a column, suspension rods, and a hanging ring. The lower end of the column is fixed to the top surface of the chassis, and a hanging ring is fixed to the upper end of the column. The axis of the hanging ring is perpendicular to the axis of the column. One to three conical bosses are integrally formed on the column along the axial direction. The bosses are smaller at the top and larger at the bottom, and the axis of the bosses is on the same straight line as the axis of the column. Each boss corresponds to a suspension rod group, and each suspension rod group consists of 2 to 4 suspension rods. These suspension rods are distributed around the column, and an angle α is formed between the suspension rod and the top of the column. The angle α is between 65° and 75°. The suspension rod is a two-section stepped shaft structure with a smaller upper section and a larger lower section. Its larger diameter end is fixed to the conical surface of the boss. This hanger can meet the requirements for suspending workpieces for shot blasting, and its structural strength is high enough to withstand the impact of high-speed steel shot.

[0004] During shot blasting operations, it was discovered that when shot blasting the spherical crown liner of railway bridge bearings, the usual shot blasting operation requires placing the bearing spherical crown liner in a support frame before hoisting the entire support frame for shot blasting. During the hoisting process, the hook and lifting ring are prone to slipping and falling off, which leads to the inability to continue the shot blasting operation. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that, during the shot blasting process of the ball crown liner of railway bridge bearings, the ball crown liner of the bearing is usually placed in a support frame and then the entire support frame is hoisted for shot blasting. During the hoisting process, the hook and the lifting ring are prone to slipping and falling off, which makes it impossible to continue the shot blasting operation.

[0006] To solve the above-mentioned technical problems, this utility model provides a shot blasting hanger for spherical crown liners of railway bridge bearings, comprising: a support frame and a positioning mechanism. A hanging frame is fixedly connected to the upper end of the support frame. A hook is provided on the inner wall of the hanging frame. A protective mechanism is provided at the position corresponding to the hook and the hanging frame. The protective mechanism includes a fixing ring. The inner wall of the fixing ring is fixedly connected to the arc surface of the hanging arm end of the hook. A rotating plate is rotatably connected to the inner wall of the fixing ring. A fixing hole is opened on one end surface of the rotating plate. An inlay frame is fixedly connected to the end of the hook away from the hanging arm. The inner wall of the inlay frame is inserted into the surface of the rotating plate. A moving rod slides through the upper surface of the inlay frame. A spring is sleeved on the arc surface of the moving rod. The two ends of the spring are fixedly connected to the inlay frame and the moving rod, respectively. The arc surface of the bottom end of the moving rod is slidably inserted into the inner wall of the fixing hole.

[0007] The effect achieved by the above components is as follows: during the shot blasting process of the spherical crown liner of railway bridge bearing, a large number of liner plates will need to be hoisted. At this time, the hooks and the hoisting frame will be connected and fixed. The protective mechanism set between the hooks and the hoisting frame can be used to perform effective protective and limiting operations.

[0008] Preferably, a pull ring is rotatably connected to the upper surface of the movable rod, and the cross-section of the pull ring is vertical.

[0009] The effect achieved by the above components is that when the position of the moving rod is stretched, the pull ring at the upper end of the moving rod can be used for auxiliary operation.

[0010] Preferably, a limiting ring is fixedly connected to the bottom arc surface of the hook, and a slot is provided on the upper arc surface of the limiting ring, the inner wall of the slot engaging with the bottom arc surface of the hook.

[0011] The effect achieved by the above components is that, with the help of the matching between the limiting ring and the slot, the hook and the hanging frame can be effectively locked and limited, preventing the hook from shaking.

[0012] Preferably, the inner wall of the inlay frame has arc-shaped cross-sections at both ends, and the cross-sectional dimensions of the inlay frame are adapted to the cross-sectional dimensions of the rotating plate.

[0013] The effect achieved by the above components is that the inlay frame with an arc-shaped inner wall cross section can be quickly snapped and fixed to the rotating plate.

[0014] Preferably, the inner wall surface of the support frame is provided with a positioning mechanism, which includes three support rings and a support rod. The surfaces of the three support rings are fixedly connected to the inner wall surface of the support frame. Both ends of the support rod are fixedly connected to a movable ring. The movable ring has a "C" shaped cross-section. The inner wall of the movable ring is slidably connected to the arc surface of the support ring. The upper arc surface of the movable ring is threaded through a pressing shaft, and the bottom end of the pressing shaft abuts against the surface of the support ring.

[0015] The aforementioned components achieve the following effects: when the liner is placed inside the support frame, the liner can be supported and limited by the combination of the support ring and the support rod. At the same time, the distance between the support rod and the support ring can be adjusted by the positioning mechanism, which helps to support and fix liners of different sizes for shot blasting operations.

[0016] Preferably, the arc surface of the extrusion shaft is provided with a plurality of auxiliary grooves, and the plurality of auxiliary grooves are evenly distributed on the arc surface of the extrusion shaft.

[0017] The effect achieved by the above components is that the extrusion shaft can be better rotated and fixed through the auxiliary groove, preventing slippage when the extrusion shaft rotates.

[0018] Preferably, the support rod and the support ring are uniformly and fixedly connected with a number of protective sleeves, and the arc surface of the protective sleeves is provided with a number of anti-slip textures.

[0019] The effect achieved by the above components is that, through the combination of the protective sleeve and the anti-slip texture, the friction between the liner and the support rod and support ring can be effectively increased.

[0020] Compared with related technologies, the shot blasting hanger for the spherical crown liner of railway bridge bearings provided by this utility model has the following beneficial effects:

[0021] This utility model provides a shot blasting bracket for the spherical crown liner of railway bridge bearings. By operating the protective mechanism, the position between the hook and the hanging frame is fixed and protected. The hook is connected by a rotating plate that rotates on the arc surface and an inlay frame fixed at one end of the hook. At the same time, the moving rod is connected and fixed by a fixing hole on the surface of the rotating plate. This helps to protect the entire hook and the hanging frame and prevent it from falling off.

[0022] By operating the positioning mechanism, the position between the support rod and the support ring can be adjusted. The sliding between the moving rings fixed at both ends of the support rod and the support ring helps to position the distance between the support rod and the support ring, which is helpful for supporting and limiting the support of spherical crown liners of different sizes.
