Technical Field
[0001] The utility model relates to the technical field of mechanical engineering, in particular to a fast-transferring stress-relieving operation rail impact device. Background Art
[0002] At present, in the stress release operation, the "roller release method" or "rail stretcher and roller release method" is used to carry out the operation according to the designed locked rail temperature and the actual on-site rail temperature conditions. The core components of these two construction methods are the rail impactor and the human pulley. The rail impactor is forged from high-strength alloy steel and fixed to the rail with an inclined iron. The impact pad is placed on the rail head, close to the plane of the rail impactor body, and connected to the rail impactor body with a hook. The human pulley is a metal structure with a wheel set inside, which can move freely along the direction of the rail. During the operation, the rail impact pulley is directly pulled by manpower, and the stress in the rail is released by repeatedly impacting the rail impact pad.
[0003] To ensure the effectiveness of the stress relief operation, the rail impactor and the manual pulley are both metal structures with high deadweight, which also brings about the problem of difficulty in transferring the stress relief operation equipment. During the stress relief operation, only the traction of the rail impact pulley requires 4-8 operators to pull the pulley back and forth to hit the rail impactor. At the same time, an additional operator is required to control the balance of the rail impact pulley. This operation method has the problems of high labor cost and the operation quality mainly relying on the operator's experience. Utility Model Content

DETAILED DESCRIPTION
[0017] In order to make the purpose, principle and structure of the utility model clearer, it is further described below in conjunction with the drawings and specific embodiments.
[0018] The utility model provides a rail collision device for stress release operation with rapid transition.
[0019] The stress release operation rail collision device designed by the present invention is an integrated structure, and the main structure is composed of a rail collision device 1, a rail collision pulley 3 and a hydraulic cylinder 2. The rail collision device 1 is composed of a rail collision device body 1.1, a collision block 1.5, a limit block 1.3, a limit bolt 1.4, a first connecting assembly 2.1 and a transfer roller 3.1. The rail collision device body 1.1 is a square metal structural member, which is fixed on the track 4 by the limit block 1.3 in a straddle structure. Two through holes are opened on both sides of the rail collision device, so that the limit bolt 1.4 can pass through the rail collision device body 1.1 to adjust the distance between the limit block 1.3 and the rail collision device body 1.1. At the same time, two grooves 1.2 are arranged inside the rail collision device for installing the transfer roller 3.1.
[0020] The impact block 1.5 is an L-shaped metal structure as a whole, and its longer section is a wedge-shaped structure. The impact block 1.5 is connected and fixed to the track impactor body 1.1 by inserting it into the corresponding groove of the track impactor body 1.1. Its shorter side is used to directly contact the track impactor pulley 3. The limit block 1.3 is a metal component, one side of which has the same shape as the track impactor body 1.1, and the other side is shaped like the top and waist of the track. At the same time, a square groove 1.6 is opened on the shaped side to reduce the overall weight of the limit block 1.3.
[0021] The limit bolts 1.4 are common metal bolts, which are arranged in two places on the corresponding surfaces of the rail collision device 1. They can adjust the distance between the limit block 1.3 and the rail collision device body 1.1 through the through holes on the rail collision device body 1.1, and are used to fix the rail collision device part before the operation starts.
[0022] The first connection component 2.1 is a boss structure, and a first connection component 2.1 is arranged on both sides of the rail bumper body 1.1, which is used to connect the rail bumper body 1.1 and the hydraulic cylinder 2. The transfer roller 3.1 is a metal roller structure, and its length and size can just fit into the internal groove 1.2 of the rail bumper body 1.1, playing an auxiliary transportation role when the equipment is transferred to the operation point.
[0023] The rail-collision pulley 3 is composed of a pulley body, a second connecting component 2.2 and a transfer roller 3.1. The rail-collision pulley is a "Π"-shaped metal structure, which is placed on the track 4 in a straddling manner through the transfer roller 3.1, and a through hole is opened inside for the transfer roller 3.1. The transfer roller 3.1 is a metal roller structure, and its length and size can just fit inside the rail-collision pulley, so that the rail-collision pulley can move forward and backward along the direction of the rail. The second connecting component 2.2 is a boss structure, and a second connecting component 2.2 is arranged on both sides of the rail-collision pulley, which is used to connect the rail-collision pulley and the hydraulic cylinder.
[0024] The hydraulic cylinder is a common hydraulic cylinder structure, which is composed of a hydraulic cylinder, a hydraulic rod and a connecting ring. The whole part provides a power source for the rail collision pulley, so that it can reciprocate and impact the rail collision device part. The connecting ring is set at the hydraulic cylinder and the hydraulic rod, and the whole is a single circular ring structure. The bolts set at the connecting ring complete the connection with the rail collision device body 1.1 and the second connecting component 2.2 of the rail collision pulley 3.
[0025] Specifically speaking:
[0026] Step 1: The operator transports the complete equipment to the area to be operated, and carries out equipment assembly, equipment debugging, real-time rail temperature measurement and calculation of rail elongation before operation in accordance with the stress relief operation standards for urban rail transit.
[0027] Step 2: Place the impact block on the top of the track, and then place the main body of the track impactor on the impact block in a straddling manner, while adjusting the distance between the impacted part of the impact block and the main body of the track impactor.
[0028] Step 3: Place two limit blocks in the gap between the rail impactor body and the rail, and ensure the connection between the rail impactor body and the rail by adjusting the limit bolts on both sides at the same time.
[0029] Step 4: Place the rail-collision trolley on the rail and make sure it can move forward and backward along the direction of the rail.
[0030] Step 5: Fix the left and right hydraulic cylinders through the connecting components of the rail impactor body and the rail impact pulley.
[0031] Step 6: Start the hydraulic cylinder. The rail-collision trolley, driven by the hydraulic cylinder, repeatedly impacts the impact block of the rail-collision device. The operator confirms whether the stress relief operation is completed by measuring the real-time elongation information of the rail.
[0032] Step 7: After completing the single-point operation, loosen the limit bolt, remove the limit block and the impact block, lift the main body of the impactor, and place the roller in the internal groove.
[0033] Step 8: The operator drags the whole equipment by manpower or auxiliary equipment on the track line to realize the transfer operation point of the whole equipment. Then repeat steps 1-6 to realize the stress release operation at each operation point.
[0034] Step 9: After completing all the work points, the operator disassembles the hydraulic cylinder and stores the various components according to the rail bumper, hydraulic cylinder, and rail bumper pulley.
