Description

Technical Field

[0001] The embodiments of the utility model belong to the technical field of anchor machine modification, and more specifically, relate to an anchor machine modification fixing device. Background Art

[0002] The failure of the casing and spike anchoring of the rail engineering fastener system is one of the reasons for the failure of urban rail transit components. Since there is a risk of detachment after the casing and spike anchoring failure, this seriously endangers the personal safety of passengers. In daily maintenance work, operators usually use anchor re-anchoring machines to re-anchor failed components such as casing and spikes.

[0003] The existing anchor change machine generally includes an impact drill and a fixing table. During the anchor change operation, the impact drill is generally aimed at the casing with failed anchoring, and then a concave hole is drilled on the rail sleeper. The threaded hole on the fixing table is aligned with the concave hole and an expansion bolt is implanted to complete the fixing of the fixing table. Finally, the impact drill is started to complete the anchor change operation. The problem with this method is that the need to drill a concave hole on the rail sleeper has a great impact on the rail sleeper, and after the anchor change operation is completed, the concave hole needs to be repaired to avoid affecting the rail sleeper structure. At the same time, the process of implanting the expansion bolt is cumbersome and the installation and disassembly efficiency of the connection between the fixing table and the rail sleeper is low, which leads to low efficiency of the anchor change operation.

[0028] Please refer to Figure 1 As shown, the present application provides a modified anchor machine fixing device 10 , which includes a base 11 , a connecting platform 12 , an insertion rod 13 and a force-bearing rod 14 .

[0029] The base 11 is used to be placed on the sleeper. Specifically, in this embodiment, since the sleeper surface is curved, the back of the base 11 is also curved to achieve the back of the base 11 to fit the sleeper surface, thereby increasing the contact surface and improving the stability of the base 11 placed on the sleeper.

[0030] The connecting platform 12 is provided with a connecting hole 121 that matches the threaded hole on the fixing platform. Specifically, when actually connecting, the anchor machine and the connecting platform 12 can be fixed by aligning the threaded hole on the fixing platform of the anchor machine with the connecting hole 121 on the connecting platform 12 and screwing in the fastener. Furthermore, the connecting platform 12 protrudes from the base 11. Specifically, the protruding height of the connecting platform 12 is greater than the height of the fastener, that is, the fastener can be screwed into the connecting platform 12.

[0031] The insertion rod 13 extends from the front side of the base 11, and the insertion rod 13 is used to be inserted into the bottom of the rail. The force rod 14 extends from the back side of the base 11, and the force rod 14 is for the operator to step on. Specifically, we call the side of the base 11 close to the rail the front side of the base 11, and the side of the base 11 away from the rail the back side of the base 11. It is easy to understand that since the force rod 14 extends from the back side of the base 11, the operator can apply downward pressure on the force rod 14 when stepping on it, thereby increasing the pressure between the base 11 and the rail, and increasing the friction between the base 11 and the sleeper, so as to improve the stability of the base 11 and the sleeper, and avoid the unstable connection between the base 11 and the sleeper due to the shaking of the impact drill when it rotates. In this case, the insertion rod 13 tilts relative to the sleeper to abut against the bottom of the rail. It is not difficult to understand that since the rail prevents the insertion rod 13 from tilting, it can avoid the unstable connection between the base 11 and the sleeper due to the shaking of the impact drill when it rotates.

[0032] It can be understood that the anchor changing machine fixing device 10 of the present application is achieved by placing the base 11 on the sleeper, and the operator steps on the force-bearing rod 14 to apply pressure to the base 11, and at the same time inserting the insertion rod 13 into the bottom of the rail to prevent the base 11 from tilting relative to the sleeper, and providing a connecting platform 12 to connect with the fixing platform, thereby avoiding the need to drill holes on the sleeper to connect the fixing platform and the sleeper. In addition, the connecting platform 12 is provided on the base 11 and the protruding height of the connecting platform 12 is greater than the height of the fastener. The fastener can be directly screwed into the connecting platform 12, and the anchor changing machine fixing device 10 can be directly withdrawn after the anchor changing work is completed. In this way, it is possible to avoid implanting the fastener into the sleeper, and there is no need for subsequent repair of the recessed holes. The anchor changing machine fixing device 10 of the present application can improve the efficiency of the anchor changing operation.

[0033] In one embodiment, two insertion rods 13 are provided, the two insertion rods 13 are provided on both sides of the base 11, and the connecting platform 12 is provided in the middle of the base 11. Specifically, in this embodiment, since the impact drill is located in front of the fixed platform, in order to ensure the stability of the impact drill, the connecting platform 12 is provided in the middle of the base 11, and the two insertion rods 13 are provided on both sides of the base 11, so that the base 11 can be stably stressed. Furthermore, the width of the base 11 is greater than the width of the sleeper. Specifically, since the rails and the sleepers are connected by pillow buckles, that is, the insertion rod 13 cannot be inserted into the pillow buckle part below the rails, setting the width of the base 11 greater than the width of the sleeper can avoid the insertion of the insertion rod 13 due to the interference of the pillow buckle. At the same time, since the positions of the anchor failure components in the width direction of the sleeper are different, the two insertion rods 13 can move in the width direction of the sleeper under the premise of interfering with the pillow buckle, thereby meeting the re-anchoring work requirements of the anchor failure components in different positions.

[0034] In one embodiment, the insertion rod 13 is connected to a vertical rod 131 at one end near the rail. It can be understood that since the pillow buckle is installed on the sleeper, the rail is raised by the pillow buckle, and the base 11 is placed on the sleeper, and the pillow buckle is relatively high, that is, there is a relatively high height gap between the base 11 and the rail, and the tilting angle of the insertion rod 13 relative to the sleeper is limited, and the vertical rod 131 can ensure that the insertion rod 13 can abut against the bottom of the rail. Further, the height of the vertical rod 131 is adjustable. Specifically, in this embodiment, the vertical rod 131 is threadedly connected to the insertion rod 13, and the vertical rod 131 is screwed in relative to the insertion rod 13, and the height of the vertical rod 131 is reduced. The vertical rod 131 is loosened relative to the insertion rod 13, and the height of the vertical rod 131 is increased. It is not difficult to understand that since the heights of the pillow buckles are different, that is, the heights of the rails relative to the sleepers are different, the use requirements of pillow buckles of different heights can be met by the vertical rod 131.

[0035] In one embodiment, the insertion rod 13 is detachably connected to the base 11. It can be understood that since there are multiple anchor failure parts, multiple re-anchoring operations are required, and the space beside the track is limited and covered with gravel, which makes it difficult for the transport vehicle to travel, that is, the anchor machine fixing device 10 needs to be carried by the operator to the next re-anchoring operation site. The insertion rod 13 and the base 11 are set to be detachably connected, and the anchor machine fixing device 10 can be disassembled into two parts to reduce the mass of each anchor machine fixing device 10, which is convenient for the operator to carry. At the same time, since the insertion rod 13 is long, the length of the anchor machine fixing device 10 is long, which is not convenient for the operator to carry. After the insertion rod 13 is disassembled, the length of the anchor machine fixing device 10 can be reduced to facilitate carrying.

[0036] In one embodiment, the base 11 is provided with stoppers 111 on both sides, and the stoppers 111 are provided with insertion holes 1111 in the direction of the rails, and the diameter of the insertion holes 1111 matches the rod diameter of the insertion rod 13. That is, the insertion rod 13 can be inserted into the stoppers 111 from the insertion holes 1111 to achieve connection with the base 11, and the insertion rod 13 can be detached from the insertion holes 1111 of the stoppers 111 to achieve separation from the base 11. The advantage of such a setting is that, under the premise of achieving detachable connection between the insertion rod 13 and the base 11, the insertion rod 13 can also be limited to avoid vertical and axial shaking of the insertion rod 13 due to shaking when the impact drill rotates.

[0037] Furthermore, the insertion hole 1111 passes through the limiter 111. That is to say, the base 11 can be moved closer to or farther from the insertion rod 13 through the insertion hole 1111 on the limiter 111. It can be understood that since the position of the vertical rod 131 on the insertion rod 13 is fixed, after the insertion rod 13 abuts against the bottom of the rail through the vertical rod 131, the insertion rod 13 cannot move at this time, and since the position of the anchor failure component in the length direction of the sleeper is different, in this case, the base 11 can move relative to the insertion rod 13 through the insertion hole 1111 on the limiter 111, so as to adjust the position of the anchor failure component and the connecting platform 12, thereby accurately aligning the impact drill with the anchor failure component.

[0038] In one embodiment, the stopper 111 is integrally formed with the base 11. Specifically, the stopper 111 and the base 11 can be integrally formed by any method such as injection molding, blow molding, mold drafting, stamping, 3D printing, etc. The advantage of integral molding is that it is convenient to produce the modified anchor machine fixing device 10, the production process is simple, the production cost is low, and at the same time, the connection tightness between the stopper 111 and the base 11 is high, thereby improving the overall structural strength of the modified anchor machine fixing device 10.

[0039] In one embodiment, the stress rod 14 and the base 11 are integrally formed. Specifically, the stress rod 14 and the base 11 can be integrally formed by any method such as injection molding, blow molding, mold drafting, stamping, 3D printing, etc. The advantage of integral molding is that it is convenient to produce the modified anchor machine fixing device 10, the production process is simple, the production cost is low, and at the same time, the connection tightness between the stress rod 14 and the base 11 is high, and the overall structural strength of the modified anchor machine fixing device 10 is improved.

[0040] In one embodiment, the base 11 is provided with a recessed opening 112 for the impact drill to work on the front side of the connecting platform 12. It can be understood that since the positions of the impact drill and the fixing platform on the modified anchor machine are fixed, the recessed opening 112 is provided on the front side of the connecting platform 12 to meet the requirements of the impact drill contacting the anchor failure component.

[0041] In one embodiment, the connecting platform 12 is made of steel. It is easy to understand that steel has the advantages of high strength, high reliability, and good pressure resistance, and can meet the connection requirements of the connecting platform 12 and the fixing platform. At the same time, since the connecting platform 12 is made of steel, the connecting platform 12 can be welded to the base 11. In addition, the weight of steel is relatively heavy, which can improve the quality of the base 11, thereby improving the stability of the base 11 and the sleeper.

[0042] In one embodiment, two stress-bearing rods 14 are provided, and the two stress-bearing rods 14 are provided on both sides of the base 11. It can be understood that the provision of two stress-bearing rods 14 can make the base 11 bear stress stably. Further, the two stress-bearing rods 14 are connected by a pedal 15, and the pedal 15 is connected to one end of the two stress-bearing rods 14 away from the base 11. The advantage of such a setting is that by extending the force arm to reduce the pressure to be applied, the operator only needs to apply a smaller pressure to ensure the stability of the base 11 and the sleeper. At the same time, the operator is more likely to step on the pedal 15 than on the stress-bearing rod 14.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
