Description
TECHNICAL FIELD
[0001] The utility model relates to railway overhead line system technical field, especially a tunnel is used to hit ice pick. BACKGROUND
[0002] Railway is mostly constructed in mountainous area, and bridge and tunnel connection is the common feature of these mountainous area railways, and most of the existing railways are constructed in early time, and the tunnel construction technology and level are not too advanced, therefore the tunnel leakage problem is common in the early construction railway, however, the tunnel leakage in winter, especially the temperature drop in northern region will cause the ice phenomenon at the leakage point of some tunnels, and the railway tunnel icing will cause the railway overhead line system tripping, bowing, and the safety driving accident;
[0003] For the tunnel icing problem, because the icing phenomenon has no obvious feature, according to the research, the tunnel icing phenomenon has no specific relation with temperature, and the icing condition is related to a series of factors such as temperature, environment and wind direction, although some methods are used in the experiment to plug the leakage at present, the cost is high, the difficulty is big, and the better effect is not obtained, therefore the railway tunnel icing in winter mainly relies on the artificial ice hitting operation to ensure the train operation safety, and the ice hitting is according to the ice condition to hit the ice at the time and place, therefore the ice hitting personnel is nervous and the work is tiring;
[0004] For the railway tunnel ice hitting, a tool ice pick needs to be used, however, because the railway running speed is fast at present, and the transportation task is heavy, the transportation capacity is increased, and the train density is big in winter, it is difficult to realize the tunnel ice hitting operation under the power-off state of the overhead line, therefore the tunnel ice hitting of these railways is mostly the indirect live working under the power-on state of the overhead line, therefore the ice pick not only needs to have good insulation performance, but also needs to have good endurance and strength under the high strength operation, and then needs to have the practical, good and light characteristics;
[0005] At present, there are many types of ice picks in the market, most of which have certain insulation, but most of them are only suitable for the operation under the power-off state of the overhead line, and the ice pick for the indirect live working of the railway tunnel needs to ensure that the collision with the contact wire does not cause the short circuit tripping problem, and the position of the pick head of this kind of ice pick which is easy to contact with the overhead line has good insulation, however, the ice pick has the following shortcomings:
[0006] Firstly, the existing ice pick for the indirect live working of the railway tunnel is not allowed to use the iron sheet to reinforce the connection to ensure the good insulation, and is only composed of an insulation rod and an insulation plate, therefore the ice pick head is easy to break from the connection after long time ice hitting operation;
[0007] Second, the existing ice pick is mostly designed in three sections, and it is difficult to reach the ice column on the tunnel top by stretching the arm straight, especially for people with low height, and sometimes the ice column on the tunnel top cannot be reached, which may cause that although the ice operation has been carried out, the ice operation effect is poor, and the ice is more likely to re-freeze and freeze for a longer length in the position where the ice is not reached, which is easy to cause safety accidents.
[0008] Third, the existing ice pick is connected by using a screw clamp, which is firm but not convenient to disassemble and assemble, especially after the operation is completed, and it is difficult to disassemble and assemble due to the force on the rod. In the long tunnel, the visibility is poor and it is not easy to walk in the tunnel, and the operation time in the tunnel is relatively long, but the vehicle needs to be avoided in the tunnel, so the ice pick needs to be disassembled and assembled when the ice needs to be punched, so the disassembly and assembly of the ice pick is not convenient, which wastes the operation time and increases the safety hidden danger. Practical new type content
[0009] The utility model provides a tunnel ice pick for solving three deficiencies of the ice pick, one is to optimize the ice pick head to improve the mechanical strength of the ice pick head and reduce the damage probability, two is to improve the three-section design of the original ice pick, lengthen the length, and make the ice operation in the tunnel more convenient, and three is to redesign the connection mode of the ice pick to make it convenient to disassemble and assemble and firm and reliable.
[0010] The utility model provides a tunnel ice pick, which comprises:
[0011] The insulating plate of the pick head is provided with a through hole in the center position, and the through hole is internally inserted with an insulating rod of the pick head.
[0012] The arc-shaped plate is arranged at the position corresponding to the through hole of the insulating plate of the pick head.
[0013] The connecting assembly is arranged in the interior of the insulating rod of the pick head, and the connecting assembly comprises a movable sleeve pipe which is slidably arranged.
[0014] The arc-shaped plate is provided with two groups, and the two groups of arc-shaped plates are symmetrically distributed.
[0015] The insulating rod of the pick head is provided with multiple groups, and the multiple groups of insulating rods of the pick head are mutually spliced.
[0016] The bottom of each insulating rod of the pick head is fixedly provided with a first connecting port, and a fixing hole is formed in each first connecting port.
[0017] The top of each insulating rod of the pick head is provided with a second connecting port corresponding to the position of the first connecting port of the bottom of the insulating rod of the pick head.
[0018] The top of each said pick head insulating rod is sleeved with a movable sleeve at the position of the second corresponding interface, and a first reset spring is fixed between the lower end surface of the movable sleeve and the pick head insulating rod.
[0019] The upper end of each said pick head insulating rod is provided with a receiving groove at the position of the fixed hole, and a ball-type clamp is inserted into the receiving groove.
[0020] A second reset spring is fixed between the end of the ball-type clamp and the inside of the receiving groove.
[0021] One end of the ball-type clamp penetrates the inner wall of the receiving groove.
[0022] The inner wall of the movable sleeve is provided with a bevel groove at the end of the ball-type clamp, and the cross section of the bevel groove is triangular.

[0024] (1) The arc-shaped plate is installed at the position of the through hole of the pick head insulating plate, the mechanical strength of the ice pick head is strengthened through the arc-shaped plate, the fracture problem of the original applicable product caused by high strength use can be effectively avoided, the work completion rate is better ensured, and the time wasted for replacing the new tool and the cost of purchasing the new tool are reduced.
[0025] (2) The length of the ice pick is increased, and the ice pick head is separated, so that the problem that the original ice pick needs to be stretched straight and is difficult to be used by people with low height in some high tunnels is effectively solved, the work efficiency is improved, and the damage of the ice pick head can be repaired by replacing only the pick head part, so that the loss cost is reduced.
[0026] (3) The novel connection method is adopted, the ice pick is more convenient to disassemble and assemble, the work time is reduced, and the safety hidden danger caused by the inconvenient disassembly and assembly of the ice pick is reduced. BRIEF DESCRIPTION OF DRAWINGS
