Description

Technical Field

[0001] The invention relates to a dismantling device, in particular to a dismantling device for dismantling adhesively bonded insulating joint clamps on railway rails. Background Art

[0002] In the construction of railways, it is necessary to lay rails over long distances for the train to move forward. For the communication of trains, it is sometimes necessary to use rails to transmit signals. In order to avoid interference between signals in different sections, realize segmented transmission of signals, and facilitate the preparation and laying of rails, rails are laid in segments. A gap is left between the ends of the two connected rails, and the gap is filled with glue to form a glue seam. The cross-section of the rail is in the shape of an "I". Two plywoods form a joint to connect the adjacent ends of two adjacent rails. The two plywoods are respectively arranged on the opposite sides of the web of the rail, and glue is arranged between the plywood and the web to increase the connection toughness between the plywood and the rail. The fixing bolts penetrate the plywood and the web to realize the fixation between the plywood and the rail. A nylon insulating tube is inserted into the connection hole between the rail and the plywood, and the fixing bolts are inserted into the insulating tube. After the plywood connects the two rails, no conductive path will be formed between the two rails.

[0003] When repairing the rails, the target rails need to be removed, so the splints at the corresponding rail joints need to be removed. For the removal of the fixing bolts, a socket wrench can be used for disassembly. Since there is glue between the splint and the web, the glue itself has strong toughness, and the matching area between the splint and the web is relatively large, even if the fixing bolts are removed, it is not easy to remove the splint from the rail. The current common practice is to melt the glue by fire roasting, and then open the splint. However, the environment where the rails are located is basically in the wilderness, and it is not easy to carry fire roasting equipment. To achieve the connection of the two rails, the splint itself is required to have a certain thickness. To melt the glue on the back of the splint by fire roasting, it is necessary to roast the splint thoroughly with fire, which is laborious and fuel-consuming. This kind of fire roasting operation is difficult and time-consuming. Fire roasting operations on rails are also prone to cause irreversible damage to the rails, and will also bring hidden dangers to operational safety. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a rail glued insulating joint clamping plate remover, which has a simple structure and is convenient for removing the clamping plate from the rail.

[0005] In order to solve the technical problem, the technical solution of the present invention is: a rail glued insulated joint splint remover, including a frame and a hydraulic device, the hydraulic device is connected to the hydraulic cylinder through an oil pipe, and a piston rod extending to the outside is provided in the hydraulic cylinder, characterized in that a wedge is movably provided on the outer end of the piston rod, the outer end of the wedge is sharp, and the outer end of the wedge is used to insert from one end of the splint into the gap between the splint and the web on the rail; the hydraulic cylinder is movably connected to one end side of the frame, and a supporting structure is provided on the other end side of the frame, and the supporting structure is used to support the other end of the splint.

[0006] The hydraulic device is similar to the hydraulic pump structure of the existing manual hydraulic jack. When working outdoors, the hydraulic pump is started by pressing the joystick to provide power to the hydraulic cylinder, so that the piston rod pushes the wedge to insert into the gap between the clamping plate and the web. A reversing valve can be set on the passage of the hydraulic oil to change the flow direction of the hydraulic oil in the oil pipe, so that the wedge can be inserted into the gap between the clamping plate and the web and can be disengaged under the drive of the piston rod. When the wedge is inserted into the gap between the clamping plate and the web, the wedge surface on the wedge will gradually push the clamping plate from one end to the outside, thereby realizing the removal of the clamping plate.

[0007] Furthermore, the wedge is hinged to the outer end of the piston rod via a pivot, which enables the wedge to be well adapted to the cooperation with the clamping plate, so that the outer end of the wedge is inserted into the gap between the clamping plate and the web.

[0008] Furthermore, the support structure includes a support rod and a fixed top block connected to one end of the support rod, the fixed top block is used to abut against the other end of the clamping plate, and the other end of the support rod is movably connected to the frame. This support structure is simple and can provide stable support for the clamping plate.

[0009] Furthermore, the fixed top block is movably connected to one end of the support rod, and the other end of the support rod is movably provided with a connection seat, and the connection seat is fixed to the other end side of the frame. The support rod can move relative to the frame, so that the disassembler can be conveniently set on the rail, and the support structure can provide stable support for the clamping plate.

[0010] Furthermore, the outer end surface of the fixed top block is a plane, which is used to collide with the other end surface of the clamping plate. The outer end surface of the fixed top block is a plane, which can well adapt to the other end surface of the clamping plate, so that the fixed top block can provide stable support for the clamping plate, and it is convenient for the fixed top block to be disengaged from the clamping plate.

[0011] Furthermore, the frame includes two end plates arranged in parallel at intervals, and a plurality of connecting rods are bridged between the two end plates; two sets of hydraulic cylinders are movably connected to one end plate, and the two sets of hydraulic cylinders are used to be arranged on opposite sides of the rail; two sets of supporting structures are movably connected to the other end plate, and the two sets of supporting structures are used to be arranged on opposite sides of the rail. The frame structure of this structure is simple and easy to prepare. The hydraulic cylinders and supporting structures are both in two sets, so that the disassembler has good stability and high efficiency when working.

[0012] Furthermore, a socket is provided at the bottom of the two end plates, and the socket is used to be connected to the rail, and the connecting rod is arranged on opposite sides of the socket. By setting the socket, the cooperation between the frame and the rail can be facilitated, and the wedge block and the supporting structure can be easily set in place.

[0013] Furthermore, a connection block is fixed on both sides of the end plate on opposite sides of the socket, and a set screw is threadedly connected to the connection block, and the inner end of the set screw is used to press against the rail. After the frame is set on the rail, the set screw is screwed so that the inner end of the set screw presses against the rail to position the frame on the rail, so that the position stability of the frame on the rail is good, which is convenient for further disassembly of the clamping plate.

[0014] Furthermore, a rail bottom locking block is detachably provided on the frame, and a buckle groove is provided on the rail bottom locking block, and the buckle groove is used to buckle from the bottom side of the rail to the joint between the ends of two adjacent rails. Since the glue between the splint and the rail is applied manually, it cannot be guaranteed that the adhesive force on the splints on the opposite sides of the rail is consistent. Therefore, during the operation, the ends of the rails may shift due to unbalanced forces on the opposite sides of the rails. By providing the rail bottom locking block, the position stability of the ends of the rails can be guaranteed, so that the disassembly stability of the splint is good, and the disassembly of the splint can be smoothly realized.

[0015] Furthermore, at least two fixing springs are provided on the frame, and a protruding rod is provided on the rail bottom locking block at opposite sides of the buckle groove, respectively, and the protruding rod is used to be inserted between the spring and the frame. By providing the spring and the protruding rod, the rail bottom locking block is fixed, the structure is simple, and the rail bottom locking block is easily fixed.

[0016] Therefore, the beneficial effects of the present invention are as follows: when the dismantler is used to dismantle the splint on the rail, after removing the fixing bolts on the splint, the dismantler can directly dismantle the splint from the rail by operating the hydraulic device, and the operation is very simple. Compared with the existing fire roasting operation, the dismantler is easy to carry, easy to operate, and has high operation safety. The piston rod in the hydraulic cylinder is pushed by the hydraulic device, so that the wedge block at the outer end of the piston rod is inserted into the gap between the splint and the web. With the movement of the piston rod, the splint is gradually raised under the action of the wedge surface on the wedge block, so that the wedge block can well adapt to the existence of the adhesive on the back side of the splint, which is convenient for the wedge block to dismantle the splint. The hydraulic cylinder and the supporting structure are arranged on the dismantler, so that the dismantling stability is good when the splint is dismantled. The wedge block can be disengaged from the gap between the splint and the rail by arranging a reversing structure on the hydraulic device, thereby facilitating the operation of the dismantler.

[0020] Combined with the attached drawings, Figure 1 The structural diagram of the rail glued insulating joint splint remover in use is shown. The ends of two adjacent rails 4 are close to each other, and a gap is formed between the ends of the two rails 4. Insulating adhesive is filled in the gap to form an adhesive seam 2. A pair of splints 10 connecting the two rails 4 are arranged on opposite sides of the rail 4. The splints 10 are located on the outer side of the web of the rail 4, and the aforementioned adhesive seam 2 is located in the middle of the length direction of the splint 10. When the splint 10 is removed by using the disassembler, the frame is placed on the rail 4, the splint 10 is located in the middle of the length direction of the frame, and the hydraulic cylinder 6 and the supporting structure on the frame are located on opposite sides of the splint 10, so that the stability during the removal operation is good.

[0021] The frame is similar to a cage structure. When the clamping plate 10 is disassembled, the frame is wrapped around the outer side of the rail 4. The structure of the frame includes two end plates 1 arranged in parallel at intervals, and a plurality of connecting rods 3 are bridged between the two end plates 1. Figure 1There are four connecting rods 3, two of which are respectively arranged on opposite sides of the rail 4. When in use, the connecting rod 3 is parallel to the rail 4. Two sets of hydraulic cylinders 6 are hinged on one end plate 1, and the two sets of hydraulic cylinders 6 are arranged on opposite sides of the rail 4. Two sets of supporting structures are movably hinged on the other end plate 1, and the two sets of supporting structures are arranged on opposite sides of the rail 4.

[0022] A piston rod 8 extending outward is movably arranged in the hydraulic cylinder 6, and a wedge 9 is arranged at the outer end of the piston rod 8. The wedge 9 is movably arranged on the outer end of the piston rod 8 through a pivot, and the outer end of the wedge 9 is sharp. A hydraulic device is arranged on the outer side of the frame, and the hydraulic device is usually a hydraulic pump, which is started and operated by a manual joystick. The hydraulic cylinder 6 is connected to the hydraulic pump through an oil pipe 7, and the hydraulic oil is driven to flow between the hydraulic pump and the hydraulic cylinder 6 by pressing the joystick. A reversing valve is arranged on the oil pipe 7, and the reversing valve can be operated to change the flow direction of the hydraulic oil in the oil pipe 7, so that the piston rod 8 can be extended to the outside of the hydraulic cylinder 6, or retracted into the hydraulic cylinder 6. The hydraulic oil pushes the piston rod 8 to move, and the piston rod 8 drives the wedge 9 to move. The outer end of the wedge 9 is inserted from one end of the clamping plate 10 into the gap between the clamping plate 10 and the web, or is disengaged from the gap between the clamping plate 10 and the web. When the wedge block 9 acts on the clamping plate 10 driven by the piston rod 8 , the supporting structure supports the other end of the clamping plate 10 .

[0023] The support structure includes a support rod 14 and a fixed top block 13, and the fixed top block 13 is movably hinged to one end of the support rod 14 through a pivot. A connecting seat 15 is welded and fixed to the other end plate 1 corresponding to the support rod 14, and the other end of the support rod 14 is hinged to the connecting seat 15 through a pivot. The outer end surface of the fixed top block 13 is a plane, and the plane is perpendicular to the axis of the support rod 14. During operation, the plane on the fixed top block 13 fits and abuts against the other end surface of the clamping plate 10, so that the fixed top block 13 can stably fit and support the other end surface of the clamping plate 10.

[0024] In order to adapt to the cooperation between the frame and the rail 4, a socket is provided at the bottom of the two end plates 1, and the connecting rod 3 is arranged on the opposite sides of the socket. When the frame and the rail 4 are matched, the socket is sleeved onto the rail 4 from the upper side. After the sleeve is in place, the wedge block 9 and the fixed top block 13 are respectively located on the outer sides of the opposite ends of the clamping plate 10.

[0025] When the disassembler is working, it is generally required that the frame and the rail 4 are relatively fixed. A connection block is welded and fixed on the opposite sides of the socket on the end plate 1, and a set screw 5 is threadedly connected to the connection block, and the set screw 5 passes through the connection block. When the frame and the rail 4 are relatively fixed, the set screw 5 is screwed so that the inner end of the set screw 5 is pressed against the side of the rail 4.

[0026] In order to prevent the dismantling device from being misaligned between the ends of two adjacent rails 4 during operation, thereby affecting the normal operation of the dismantling device, a rail bottom locking block 12 is detachably provided on the frame. The rail bottom locking block 12 is made of iron and is provided with a buckle groove 16. The buckle groove 16 is slightly larger than the thickness of the rail 4. The buckle groove 16 is used to buckle from the bottom side of the rail 4 to the joint between the ends of two adjacent rails 4. At least two fixed springs are provided on the frame. The fixed springs are arranged along the length direction of the connecting rod 3 on the bottom side. The two ends of a fixed spring are fixed on the bottom side of a connecting rod 3, and the fixed spring is in a tensioned state. A protruding rod 11 is respectively connected and fixed to the opposite sides of the buckle groove 16 on the rail bottom locking block 12. The protruding rod 11 is inserted between the spring and the connecting rod 3 to achieve connection and fixation with the frame.

[0027] In order to facilitate the movement of the dismantling device, a lifting handle is fixed on each of the two end plates 1. Usually, two people move and install the dismantling device by lifting the handle.

[0028] Before using this disassembler to disassemble the clamp 10, it is necessary to remove the fixing bolts on the clamp 10, and at the same time, remove the fixing bolts and fasteners on the sleeper rail corresponding to the clamp 10. When performing the operation, two operators are required to cooperate. The two operators overlap the disassembler from the position of the clamp 10 on the rail 4, so that the socket on the end plate 1 is sleeved on the rail 4 from the upper side. Pull the hydraulic cylinder 6 and the support rod 14 toward the rail 4, so that the inner side of the wedge block 9 on the opposite sides of the rail 4 fits with the surface of the web on the rail 4, and the outer end of the fixed top block 13 extends into the other end of the clamp 10. One operator presses the joystick to make the hydraulic pump supply oil to the hydraulic cylinder 6, and the other operator always pays attention to the outer end of the wedge block 9 and the clamp 10. In case of unexpected situations, a warning can be issued in time. If necessary, use tools to knock the wedge block 9 and the fixed top block 13 to make them fit with the surface of the web on the rail 4. Sometimes the wedge block 9 cannot successfully open the clamping plate 10 from the rail 4 from one end of the clamping plate 10. After the wedge block 9 is disengaged from between the clamping plate 10 and the web, the remover can be reversed to allow the wedge block 9 to remove the clamping plate 10 from the other end of the clamping plate 10.
