Description

Technical Field

[0001] This utility model relates to the field of railway laying technology, and in particular, to a semi-automatic elastic bar installation device. Background Technology

[0002] Rail transit systems use locomotives to run on fixed tracks. They have the advantages of high operating speed, large carrying capacity, low environmental impact, low energy consumption and high safety, and can expand urban space.

[0003] Railway rails are the foundation supporting locomotive movement. Rails need to be securely and reliably fixed to ensure the normal operation of vehicles. Rails are fixed to sleepers on the ballast bed using elastic fasteners. The fastening element of the elastic fastener is mainly a spring clip. Through the bending and twisting deformation of the spring clip, a fastening force is generated on the rail, thereby ensuring a reliable connection between rails, maintaining the integrity of the track for as long as possible, preventing longitudinal and lateral movement of the rails relative to the sleepers, and ensuring the correct track gauge.

[0004] In China, the elastic clips used in urban rail transit systems with 60kg / m steel rails are generally divided into two types: ω-type elastic clips and e-type elastic clips. As a boltless fastener, the e-type elastic clip has been widely used in urban rail transit lines due to its advantages of easy installation and low maintenance workload.

[0005] Currently, the installation of E-type elastic clip fasteners still requires manual labor. During assembly, an elastic clip wrench is used to pull the E-type elastic clip on the sleeper to fix the rail in place. The assembly process is labor-intensive, time-consuming, and inefficient. Furthermore, since the bottom side of the rail directly contacts the force-bearing part of the elastic clip wrench, it can damage the coating on the insulating and corrosion-resistant surface of the rail, leading to a reduction in the service life of the rail and posing a safety hazard. Utility Model Content

[0006] This utility model provides a semi-automatic spring clip installation device to solve the technical problem that the installation of existing E-type spring clips is not only time-consuming and labor-intensive, but also inefficient, and will damage the coating on the surface of the insulating and corrosion-resistant rail, resulting in a reduction in the service life of the rail and posing safety hazards.

[0007] According to one aspect of the present invention, a semi-automatic elastic bar installation device is provided, comprising a slide rail, a first support seat for supporting a first end of the slide rail, a second support seat for supporting a second end of the slide rail, a clamping mechanism slidably arranged on the slide rail for driving the elastic bar for assembly, a driving device arranged on the first support seat for driving the clamping mechanism to move along the slide rail, and a linear telescopic mechanism for abutting against a pad to position the semi-automatic elastic bar installation device. Two sets of the linear telescopic mechanisms are respectively arranged on the first support seat and the second support seat, and the two sets of the linear telescopic mechanisms extend towards each other to abut against the pad for positioning.

[0008] Furthermore, the linear telescopic mechanism includes a screw and an abutment block disposed on the end of the screw facing the pad. The screw of one set of the linear telescopic mechanisms is screwed to the first support seat, and the screw of the other set of the linear telescopic mechanisms is screwed to the second support seat.

[0009] Furthermore, the abutment block is rectangular in shape, and the abutment block is hinged to the end of the screw facing the pad.

[0010] Furthermore, a handle is provided on the end of the screw that is away from the pad.

[0011] Furthermore, the slide rail includes a first mounting base disposed on the first support base, a second mounting base disposed on the second support base, a guide rail and a lead screw disposed between the first mounting base and the second mounting base, the clamping mechanism being slidably connected to the guide rail, the lead screw being driven by a driving device, and the lead screw being screwed to the clamping mechanism.

[0012] Furthermore, the clamping mechanism includes a slider that can move along the slide rail and a clamping seat disposed on the slider.

[0013] Furthermore, the slider is equipped with a distance measuring sensor for monitoring the distance between the slider and the first support and / or the second support.

[0014] Furthermore, the slider is provided with an oil nozzle for adding lubricant.

[0015] Furthermore, an adjusting pad is provided between the slider and the clamping seat to adjust the height difference between the clamping seat and the pad.

[0016] Furthermore, a clamping groove adapted to the elastic bar is provided on the bottom surface of the clamping seat.

[0017] This utility model has the following beneficial effects:

[0018] This utility model discloses a semi-automatic spring clip installation device. The device comprises a first support base, a second support base, and a slide rail forming a gantry structure. In use, the spring clip is first aligned with the iron seat on the pad. Then, the gantry structure is placed across the iron seat, ensuring the slide rail is parallel to the insertion direction of the spring clip. Simultaneously, the clamping mechanism aligns with and clamps the spring clip. The first and second support bases then abut against the two sides of the pad via a linear telescopic mechanism, fixing the semi-automatic spring clip installation device to the pad. The drive device moves the clamping mechanism along the slide rail, inserting the spring clip into the iron seat. After assembly, the linear telescopic mechanism is retracted, separating the spring clip from the clamping mechanism, allowing the device to proceed to the next installation point. The insertion of the spring clip into the iron seat is assisted by the drive device, which not only reduces the labor intensity of spring clip assembly, saves assembly time, and improves assembly efficiency, but also prevents the spring clip wrench from damaging the insulating and corrosion-resistant coating on the side of the rail base, thus ensuring the service life of the rail and eliminating safety hazards.

[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0029] Please refer to the following: Figures 1 to 5 The semi-automatic spring clip installation device of this embodiment includes a slide rail 1, a first support seat 2 for supporting the first end of the slide rail 1, a second support seat 3 for supporting the second end of the slide rail 1, a clamping mechanism 4 slidably arranged on the slide rail 1 for driving the spring clip 203 for assembly, a driving device arranged on the first support seat 2 for driving the clamping mechanism 4 to move along the slide rail 1, and a linear telescopic mechanism 6 for abutting against the pad 201 to position the semi-automatic spring clip installation device. The two sets of linear telescopic mechanisms 6 are respectively arranged on the first support seat 2 and the second support seat 3, and the two sets of linear telescopic mechanisms 6 extend towards each other to abut against the pad 201 for positioning.

[0030] In this embodiment, the semi-automatic spring clip installation device comprises a gantry structure consisting of a first support base 2, a second support base 3, and a slide rail 1. In use, the spring clip 203 is first aligned with the iron seat 202 on the pad 201. Then, the gantry structure is placed across the iron seat 202, ensuring the slide rail 1 is parallel to the insertion direction of the spring clip 203. Simultaneously, the clamping mechanism 4 aligns with and clamps the spring clip 203. Then, the first support base 2 and the second support base 3 abut against the two sides of the pad 201 via a linear telescopic mechanism 6, fixing the semi-automatic spring clip installation device to the position of the pad 201. The drive mechanism... The drive clamping mechanism 4 moves along the slide rail 1 to insert the spring clip 203 into the iron seat 202. After the spring clip 203 is assembled, the linear telescopic mechanism 6 is retracted to separate the spring clip 203 from the clamping mechanism 4, and then the assembly operation can proceed to the next installation point. The process of inserting the spring clip 203 into the iron seat 202 is assisted by the drive device, which not only reduces the labor intensity of assembling the spring clip 203, saves assembly time, and improves assembly efficiency, but also avoids the spring clip wrench from damaging the insulating and corrosion-resistant coating on the side of the rail bottom of the rail 100, thereby ensuring the service life of the rail 100 and eliminating safety hazards.

[0031] like Figure 2As shown, in this embodiment, the linear telescopic mechanism 6 includes a screw 61 and an abutment block 62 disposed on the end of the screw 61 facing the pad 201. One set of screws 61 of the linear telescopic mechanism 6 is screwed to the first support base 2, and the other set of screws 61 of the linear telescopic mechanism 6 is screwed to the second support base 3. Optionally, a buffer layer is provided on the abutment surface of the abutment block 62 that abuts the pad 201. On the one hand, this can reduce the wear between the abutment block 62 and the pad 201 and extend the service life of the abutment block 62. On the other hand, it can increase the friction between the abutment block 62 and the pad 201, prevent the abutment block 62 from slipping off during the assembly of the spring clip 203, and improve the stability of the semi-automatic spring clip installation device. Optionally, the screw 61 is driven by a motor, and a pressure sensor is installed on the screw 61. The motor drives the screw 61 to rotate, causing the abutment block 62 to extend toward the pad 201. When the abutment block 62 abuts against the side of the pad 201, the pressure detected by the pressure sensor begins to rise, and the motor continues to rotate. When the pressure detected by the pressure sensor exceeds the preset value, the motor stops rotating. The linear telescopic mechanism 6 driven by the motor can further improve the degree of automation and increase the assembly efficiency of the spring strip 203.

[0032] In this embodiment, the abutment block 62 is cylindrical and fixedly mounted on the screw 61. The cylindrical abutment block 62 rotates with the screw 61 without interfering with the track bed, resulting in a simple structure and easy manufacturing. Optionally, each set of linear telescopic mechanisms 6 includes at least two screws 61 arranged side-by-side. By increasing the number of cylindrical abutment blocks 62, the contact points between the linear telescopic mechanism 6 and the side of the pad 201 are increased, thereby improving the stability of the semi-automatic elastic strip installation device.

[0033] like Figure 3 As shown, in this embodiment, the abutment block 62 is rectangular in shape. The abutment block 62 is hinged to the end of the screw 61 facing the pad 201. During the rotation of the screw 61, the rectangular abutment block 62 does not rotate with the screw 61, thereby maintaining parallelism with the pad 201 and avoiding interference with the track bed. By increasing the base area of ​​the rectangular abutment block 62 and the side of the pad 201, the stability of the semi-automatic spring strip installation device is improved. Each operation only requires rotating one screw 61, which can improve the assembly efficiency of the spring strip 203.

[0034] like Figure 3As shown, in this embodiment, a handle 63 is provided on the end of the screw 61 facing away from the pad 201, which can increase the torque of rotating the screw 61 and reduce the difficulty of operation. Optionally, the handle 63 passes through the screw 61, and the handle 63 can slide relative to the screw 61 along its own axis. In use, the first end of the handle 63 is pulled outward to ensure that the second end of the handle 63 will not interfere with the track bed when rotating the screw 61, which can further increase the torque of rotating the screw 61 and make operation more effortless. Optionally, limit blocks are provided on both ends of the handle 63 to prevent the handle 63 from slipping off the screw 61.

[0035] like Figure 2 and Figure 3 As shown, in this embodiment, the slide rail 1 includes a first mounting base 11 mounted on a first support base 2, a second mounting base 12 mounted on a second support base 3, a guide rail 13 and a lead screw 14 positioned between the first mounting base 11 and the second mounting base 12. The clamping mechanism 4 is slidably connected to the guide rail 13. The lead screw 14 is driven by a driving device and is screwed to the clamping mechanism 4. When assembling the spring clip 203, the clamping mechanism 4 clamps the spring clip 203, and the driving device drives the lead screw 14 to rotate, causing the clamping mechanism 4, screwed to the lead screw 14, to move along the guide rail 13. This allows the clamping mechanism 4 to drive the spring clip 203 into the iron base 202. The structure is simple, the operation is convenient, and it improves the efficiency of spring clip 203 assembly. Optionally, the driving device is a motor. Optionally, the motor is located inside the first support base 2, and the motor drives the lead screw 14 to rotate via a gear assembly. The first support base 2 provides a good working environment for the motor, preventing damage from external impacts. Optionally, the motor is mounted on the first mounting base 11 for easy maintenance and repair.

[0036] like Figure 2 and Figure 4 As shown, in this embodiment, the clamping mechanism 4 includes a slider 41 that can move along the slide rail 1 and a clamping seat 42 arranged on the slider 41. When assembling the spring bar 203, the clamping seat 42 clamps the spring bar 203, and the driving device drives the lead screw 14 to rotate, so that the slider 41 screwed to the lead screw 14 moves along the guide rail 13, thereby causing the clamping seat 42 to drive the spring bar 203 to be inserted into the iron seat 202. Its structure is simple, the operation is convenient, and it can improve the efficiency of spring bar 203 assembly.

[0037] like Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, a distance sensor 43 is provided on the slider 41 to monitor the distance between the slider 41 and the first support 2 and / or the second support 3. The distance sensor 43 monitors the distance between the slider 41 and the first support 2 and / or the second support 3 and feeds the distance information back to the controller 5. The controller 5 calculates the assembly stroke of the slider 41 based on the distance information and sends the stroke information to the drive device, thereby achieving precise assembly of the spring clip 203. Optionally, the distance sensor 43 is a laser distance sensor, which is less affected by weather and has high distance measurement accuracy, ensuring the accuracy of the spring clip 203 assembly. Optionally, the distance sensor 43 is an infrared distance sensor, which can significantly reduce the production cost of the semi-automatic spring clip installation device. Optionally, the controller 5 integrates a switch for the semi-automatic spring clip installation device.

[0038] like Figure 5 As shown, in this embodiment, the slider 41 is provided with an oil nozzle 44 for adding lubricant. The oil nozzle 44 guides the lubricant to the contact surfaces between the slider 41 and the guide rail 13 and between the slider 41 and the lead screw 14 through an oil passage opened in the slider 41. This can reduce the friction between the slider 41 and the guide rail 13 and between the slider 41 and the lead screw 14, reduce the wear between parts, and thus extend the service life of the semi-automatic spring bar installation device.

[0039] like Figure 4 and Figure 5 As shown, in this embodiment, an adjusting pad 45 is provided between the slider 41 and the clamping seat 42 to adjust the height difference between the clamping seat 42 and the pad 201. By replacing the adjusting pad 45 with different thicknesses, the height difference between the clamping seat 42 and the pad 201 can be adjusted, thereby ensuring that the elastic bar 203 can be smoothly inserted into the iron seat 202 on the pad 201 when it is clamped by the clamping seat 42. This is suitable for different types of elastic fasteners.

[0040] like Figure 1 and Figure 4 As shown, in this embodiment, a clamping groove 46 adapted to the elastic bar 203 is provided on the bottom surface of the clamping seat 42. In use, the elastic bar 203 is inserted into the clamping groove 46, and the slider 41 drives the elastic bar 203 to insert into the iron seat 202 through the clamping seat 42. Its structure is simple and the processing cost is low. Optionally, the clamping seat 42 is made of magnetic material to prevent the elastic bar 203 from loosening. Optionally, the clamping seat 42 is provided with buckles adapted to the clamping groove 46. After the elastic bar 203 is inserted into the clamping groove 46, the buckles and the clamping groove 46 cooperate to lock the elastic bar 203, thereby preventing the elastic bar 203 from loosening. After the elastic bar 203 is assembled, the buckles are removed and the linear telescopic mechanism 6 is retracted to separate the clamping seat 42 from the elastic bar 203.

[0041] In this embodiment, the clamping seat 42 is provided with grippers for gripping the spring bar 203, and the grippers are driven by an external air source.

[0042] Please refer to the following: Figures 1 to 5 In this embodiment, the semi-automatic spring clip installation device comprises a gantry structure consisting of a first support base 2, a second support base 3, and a slide rail 1. During use, the spring clip 203 is first aligned with the iron seat 202 on the pad 201. Then, the gantry structure is placed across the iron seat 202, ensuring that the guide rail 13 is parallel to the insertion direction of the spring clip 203. Simultaneously, the clamping groove 46 on the clamping seat 42 is aligned with the spring clip 203, causing the spring clip 203 to engage in the clamping groove 46. Then, the screws 61 on the first support base 2 and the second support base 3 are rotated, causing the first support base 2 and the second support base 3 to abut against the two sides of the pad 201 via rectangular abutment blocks 62, thereby securing the spring clip 203. The relative position of the clamping seat 42 and the pad 201 is fixed. The driving device drives the slider 41 to move along the guide rail 13, so that the clamping seat 42 inserts the spring clip 203 into the iron seat 202. After the spring clip 203 is assembled, the screws 61 on the first support seat 2 and the second support seat 3 are rotated respectively to retract the linear cuboid abutment block 62 and lift it upward into a gantry structure to separate the spring clip 203 from the clamping seat 42. The above operation is repeated at the next installation point to efficiently complete the assembly operation of the spring clip 203. This avoids the spring clip wrench from damaging the insulating and corrosion-resistant coating on the side of the rail bottom of the rail 100, thereby ensuring the service life of the rail 100 and eliminating safety hazards.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
