Description

Technical Field

[0001] The invention belongs to railway maintenance equipment and is applied to the field of stress release of railway seamless line rails and longitudinal movement of long rails. Background Art

[0002] With the development of the national economy, it is urgent to increase the speed of railway traffic. Seamless track is an important part of railway modernization. It is suitable for high-speed and heavy-load trains and prolongs the service life of rails. This technical field includes welding and lengthening rails on railway lines to form seamless tracks and stress relief of seamless tracks.

[0003] Seamless rail welding refers to welding 500-meter-long rails together to form 1-2 kilometers or even several kilometers of long rails. Before welding the rails, the rails scattered beside the line (i.e., the lower rails) are firstly collided by hand to make the two rail ends reach a predetermined distance. At present, a rail collision machine that relies on manpower to complete the above work is used, such as Figure 1 As shown: It is composed of a rail-collision bag and a rail-collision pulley. The rail-collision bag is composed of a bag body, an inclined iron and a positioning block. The bag body is a door-shaped structure, the inclined iron is located below the door of the bag body, and the positioning blocks are located on both sides of the lower jaw of the rail. When the inclined iron is tightened, the rail-collision bag is locked on the rail.

[0004] The rail-collision pulley is a door-shaped structure, lying on the top of the rail head. The pulley is equipped with rollers to facilitate the pulley to slide along the top of the rail. The pulley weight is 350 kg and 500 kg. When the rail is collided, it is operated by 8 people, and the rope is used to pull the pulley back and forth to hit the inclined iron of the rail collision package, driving the rail to move about 5-10 mm / time.

[0005] In addition, stress relievers are widely used in the construction of seamless rail stress relief: when the rail temperature is lower than the designed locking rail temperature, in order to increase the locking temperature of the rail, the stress reliever is used to stretch the rail and then re-lock it to reach the designed locking rail temperature. During the construction, due to the limited tonnage of the stress reliever traction rail, 2-3 additional rail collision groups are often arranged on a 1-2 km long line.

[0006] The above-mentioned manual rail-collision method is used to collide the long rail to assist the stress releaser. Both of the above-mentioned construction operations are completed by manual rail-collision machines, which are heavy, labor-intensive, and inefficient, bringing many inconveniences to the mobile construction operations on the line. Summary of the invention

[0007] In order to avoid the shortcomings of the above-mentioned technology, the present invention provides a catapult rail collision machine which replaces heavy physical strength with mechanization, is easy to operate, has high work efficiency, and is convenient for on-site mobile construction operations.

[0008] The present invention is implemented according to the following technical scheme: a hydraulic pump station and a rail-collision machine are programmed and linked, so that the cylindrical helical compression spring of the rail-collision machine can achieve intermittent contraction and elastic force release, and the spring potential energy released by the rail-collision machine is converted into the kinetic energy of the power head, so that the power head can reciprocate at high speed to collide with the rail-collision package, thereby driving the rail to move.

[0009] The ejection rail-collision machine consists of a rail-collision machine, a hydraulic pump station and a rail-collision package. During construction, the rail-collision machine and the rail-collision package are placed opposite each other on the same rail. The hydraulic pump station is connected to the rail-collision machine with a high-pressure hose to provide power to the rail-collision machine. The main structure of the rail-collision machine consists of two mutually superimposed and sliding square frames: the square frame body is composed of the front and rear machine bases and two machine body oil cylinders, and the two guide rods-cylindrical helical compression spring pairs pass through the main shaft holes of the machine base and are fastened to the front and rear power heads, and the pull rods are fastened to the power heads as a whole.

[0010] The rail collision bag consists of a bag body, an inclined iron and a positioning block. The bag body is a door-shaped structure, and the inclined iron is located between the bag body entrance and the top surface of the rail, and its inclined surface matches the bag body entrance. Positioning blocks are provided on both sides of the rail under the bag body entrance. When the inclined iron is tightened, the rail collision bag is locked on the rail.

[0011] Rail collision machine line construction is divided into two working conditions: online and offline. Therefore, there are two positioning methods for rail collision machine on the line: when the rail collision machine is used for online rail collision operation (refer to Figure 2 .3.4): The base (5) of the rail collision machine is locked on the rail sleeper (2) by means of screws (4), rail sleeper belts (3), and rail sleeper fasteners (1); when the rail collision machine is used for offline rail collision operations (refer to Figure 6 ): The rail collision machine base (5) is "rooted" on the online rail (8): The rail collision machine base (5) is fastened to the online rail collision rail bag (19) through a positioning plate (17) and bolts (16.18). The collision rail bag (19) is a door-shaped structure lying on the top of the rail head. Oblique iron grooves are provided on both sides of the collision rail head. The collision rail bag is fastened to the rail as a whole by tightening the oblique iron (20).

[0012] The hydraulic system of the hydraulic pump station and the rail collision machine is composed of an oil tank, an oil filter, a gear pump, an electric motor (or a gasoline engine), a sequence valve, a three-position four-way solenoid reversing valve, a pressure relay, a manual control button, a three-position four-way solenoid reversing valve, a pressure relay, a pressure gauge, a locking cylinder, a body cylinder and connecting pipes and wires between the hydraulic components.

[0013] Principle of the Invention

[0014] The present invention adopts a hydraulic pump station-rail-collision machine program-controlled linkage. The pressure energy of the oil output by the hydraulic pump station is converted into the mechanical energy of the power head, so that the cylindrical helical compression spring of the rail-collision machine is intermittently compressed and the elastic force is released. Then the spring potential energy released by the rail-collision machine is converted into the kinetic energy of the power head. The power head reciprocates at high speed to collide with the rail-collision package, driving the rail to move.

[0015] The main structure of the rail collision machine consists of two superimposed and slidably matched square frames: the square frame body is composed of the front and rear machine bases and two machine body cylinders, the two guide rods - cylindrical helical compression spring pairs pass through the main shaft holes of the machine base and are fastened to the front and rear power heads, and the pull rod is fastened to the power head as a whole.

[0016] The construction of the rail-collision machine line is divided into two working conditions: online and offline. Therefore, there are also two positioning methods for the rail-collision machine on the line: Online rail-collision operation of the rail-collision machine: the rail-collision machine is placed horizontally on the online rail, and the base of the rail-collision machine is locked on the sleeper through the sleeper belt and sleeper fasteners. Offline rail-collision operation of the rail-collision machine: the base of the rail-collision machine is "rooted" on the online rail: the base of the rail-collision machine is fastened to the online rail and the rail-collision bag as a whole through the positioning plate and bolts. The rail-collision bag is a gate-shaped structure that is placed horizontally on the head of the rail. There are oblique iron grooves on both sides of the rail head of the rail-collision bag. When the oblique iron is tightened, the rail-collision bag is fastened to the rail as a whole.

[0017] The hydraulic system of the rail collision machine is composed of an oil tank, an oil filter, a gear pump, an electric motor (or a gasoline engine), a sequence valve, a three-position four-way solenoid reversing valve, a pressure relay, a manual control button, a three-position four-way solenoid reversing valve, a pressure relay, a pressure gauge, a locking cylinder, a body cylinder and connecting pipes and wires between the above-mentioned hydraulic components.

[0018] According to the working condition requirements, the three-position four-way electromagnetic reversing valve (10-9) is provided with a manual button (10-8) to control the opposite locking oil cylinder (12) to adjust the impact force of the collision rail.

[0019] Construction process

[0020] 1. Construction of seamless track stress release and rail collision on rail collision machine line (refer to Figure 2 , 3, 4, 7)

[0021] (1) Place the two sleeper belts on the sleepers on both sides of the rail through the sleeper bolt holes.

[0022] (2) Place the rail impact machine horizontally on the rail head and fasten the rail impact machine body to the rail sleeper belt with rail sleeper bolts.

[0023] (3) Place the inclined iron with the inclined surface facing upward on the rail head, with the end face of the inclined iron at a predetermined distance from the power head. Place the door-shaped rail collision package horizontally on the inclined iron, and put the positioning blocks into the positioning grooves on both sides of the upper rail at the door of the package body. Tighten the inclined iron, and the rail collision package will be locked on the rail.

[0024] (4) The rail collision machine body oil cylinder (15), the three-position four-way electromagnetic reversing valve (10-6), the locking oil cylinder (12) and the three-position four-way electromagnetic reversing valve (10-9) are respectively connected by high-pressure hoses.

[0025] (5) Start the electric oil pump station (or gasoline engine pump station), idle the oil pump, and energize IYA. Then the hydraulic pump station - rail impact machine enters the programmed operation condition. The power head of the rail impact machine reciprocates and intermittently impacts the inclined iron of the rail impact package, driving the rail to move.

[0026] (6) If the impact force of the rail impact machine needs to be reduced, the manual control button (10-8) can be pressed to control the three-position four-way electromagnetic reversing valve (10-9) to change direction: the locking cylinder (12) is locked, the pull rod (11) is released, and the impact force of the rail impact machine on the rail is steplessly adjusted (special working conditions).

[0027] 2. Rail collision construction under rail collision machine line (refer to Figure 6 )

[0028] (1) A rail collision package (19) is placed horizontally on the top of the online rail (8) and the position of the rail collision package (19) on the rail is adjusted longitudinally so that it is opposite to the base (5) of the offline rail collision machine. The rail collision package (19) and the base (5) of the collision machine are locked by a positioning plate (17) and bolts (16, 18).

[0029] (2) The inclined iron (20) is placed in the positioning grooves on both sides of the rail head of the rail collision bag (19), and the inclined iron is tightened with a sledgehammer, so that the rail collision machine lying on the line lower rail (21) "takes root" on the line upper rail (8).

[0030] (3) The rail collision machine body oil cylinder (15) and the three-position four-way electromagnetic reversing valve (10-6) are connected with high-pressure hoses, and the locking oil cylinder (12) and the three-position four-way electromagnetic reversing valve (10-9) are connected.

[0031] (4) The oil pump station is started, the oil pump runs idle, and IYA is energized, so that the hydraulic pump station-rail bumper enters the program operation condition, and the line lower rail (21) moves longitudinally on the shoulder rail sleeper.

[0032] Compared with the prior art, the characteristics of the present invention are as follows: the ejection rail collision machine is used for stress release of railway seamless lines and longitudinal movement of long rails, and the traditional manual rail collision weighing 500 kg operated by 8 people is transformed into an automatic rail collision operation operated by 2 people, and the impact energy (longitudinal displacement speed) generated on the rails is equivalent to that of the manual rail collision device, and continuous rail collision without rest is possible, and the operation speed is fast. Therefore, the present invention is a kind of mechanization instead of heavy physical strength, with high work efficiency, low labor intensity, easy operation, and convenient on-site mobile construction operations.
