TECHNICAL FIELD
[0001] The utility model relates to the technical field of split pantograph, and specifically relates to a split pantograph for electric locomotive. BACKGROUND
[0002] The pantograph (also known as a trolley pole) is an electric device for electric locomotive to obtain power from the contact net, which is installed on the top of the locomotive or motor car. The pantograph can be divided into four categories: double-arm type, single-arm type, vertical type and Shizhu type. The single-arm pantograph and the double-arm pantograph are composed of a slide plate, an upper frame, a lower arm rod (a lower frame for the double-arm pantograph), a base frame, a pantograph lifting spring, a transmission cylinder, a support insulator and other components.
[0003] A Chinese patent with the publication number CN214929021U discloses an automatically adjustable pantograph for electric locomotive, which is characterized by including a slide plate and a base. The base is provided with a pantograph lifting and lowering mechanism. The front end of the base is provided with two oppositely placed extension plates. A rotating rod is fixed between the two extension plates. A first connecting cylinder is arranged on the rotating rod. The first connecting cylinder rotates around the rotating rod and is fixedly connected to one end of a lower arm rod. The pantograph lifting and lowering mechanism is connected to the lower arm rod and the first connecting cylinder. The other end of the lower arm rod is fixedly provided with a U-shaped joint. One end of a first connecting piece is rotatably connected to the U-shaped joint. The other end of the first connecting piece extends out of the U-shaped joint and is connected to a support plate fixed on the base through an auxiliary arm rod. The design has the advantages of simple structure, easy manufacturing and high efficiency.
[0004] In the prior art, the contact frame part of the pantograph is prone to damage during long-term use. Therefore, the contact frame part is designed as a two-segment structure assembled by a threaded connection. However, when assembling the contact frame, the threaded connection area needs to be connected to a threaded rod first, and then the threaded rod is rotated. At this time, the operator needs to support a part of the contact frame structure, which makes the installation more complex. SUMMARY
[0005] The split pantograph for electric locomotive provided by the utility model solves the problems in the prior art.
[0006] To solve the above technical problems, the technical scheme of the utility model is as follows:
[0007] The embodiment of the utility model provides a split pantograph for electric locomotive, which comprises:
[0008] A pneumatic base;
[0009] An adjusting frame is installed on the surface of the pneumatic base and is used in linkage with the pneumatic base.
[0010] A threaded sleeve is threaded onto the surface of the adjusting frame to facilitate connection between the adjusting frame and other parts.
[0011] The contact frame, rotatably connected to the surface of the threaded sleeve, is used to help the electric vehicle operate;
[0012] An auxiliary device is installed on the surface of the adjustment frame baffle to facilitate the connection between the threaded sleeve and the adjustment frame;
[0013] An adsorption device is installed on the surface of the pneumatic base to assist in fixing the pneumatic base to the surface of the locomotive.
[0014] Furthermore, the auxiliary device includes two connecting seats, both of which are fixedly connected to the adjusting frame. A plug rod is slidably connected to the surface of each of the two connecting seats. A rectangular groove is formed on the surface of each of the two connecting seats. A ring is rotatably connected to the surface of the threaded sleeve. A sliding plate is fixedly connected to the surface of the ring. The size of the sliding plate is adapted to the rectangular groove. A circular hole is formed on the surface of the sliding plate. The size of the circular hole is adapted to the size of one end of the plug rod.
[0015] With the above technical solution, the slide plate is connected to the rectangular groove. At this time, the threaded sleeve is connected to the contact frame at the connection position of the adjustment frame. No manual support is required from the operator. The operator can rotate the threaded sleeve to stably connect the adjustment frame and the contact frame, and the insertion rod can be inserted into the inside of the circular hole for further limiting.
[0016] Furthermore, a filler sleeve is glued to the surface of the insertion rod. The filler sleeve is made of rubber and has an octagonal cross-section.
[0017] Through the above technical solution, the filler sleeve can further fill the connection between the filler sleeve and the circular hole, and the special shape of the filler sleeve can facilitate its entry into the circular hole.
[0018] Furthermore, two elastic ropes are fixedly connected to the surface of the insertion rod, and the ends of the two elastic ropes away from the insertion rod are fixedly connected to the connecting seat.
[0019] With the above technical solution, when inserting the skateboard, the insertion rod needs to be lifted. Due to the addition of the elastic rope, a quick connection can be achieved when the circular hole aligns with one end of the insertion rod.
[0020] Furthermore, two limiting rods are fixedly connected to the surface of the ring, and both limiting rods are fixedly connected to the contact frame.
[0021] Through the above technical solution, the limiting rod can limit the ring when it is placed, so that it will not rotate when it is not in use.
[0022] Furthermore, the adsorption device includes two limiting seats, both of which are fixedly connected to the lower surface of the pneumatic base. Adhesive plates are fixedly connected to the surfaces of both limiting seats, and sliding rods are slidably connected to the surfaces of both limiting seats. A suction cup is fixedly connected to the end of the sliding rod away from the limiting seat, and a pressure plate is slidably connected to the surfaces of both limiting seats.
[0023] The above technical solution allows the pneumatic base to be easily fixed to the surface of the locomotive by pressing the suction cup with the pressure plate. This makes it convenient for operators to fix the pneumatic base and the locomotive with threaded parts, and the base will not move during the fixing process.
[0024] Furthermore, four pull ropes are fixedly connected to the surface of the pressure plate. The four pull ropes are arranged in pairs, and the end of each pair of pull ropes away from the pressure plate is fixedly connected to the surface of the suction cup.
[0025] With the above technical solution, when it is necessary to remove the suction cup from the adsorption effect, the pressure plate can be pulled upwards, and then the pressure plate can be rotated, so that the pressure plate, together with the pull rope, causes the two sides of the suction cup to be lifted up, thereby removing the adsorption effect.
[0026] Furthermore, two auxiliary rods are fixedly connected to the surface of the pressure plate, and both auxiliary rods are in the shape of a "T".
[0027] Through the above technical solution, the auxiliary rod makes it easier for operators to operate the pressure plate, reducing the complexity of the operation when the adsorption device is at the bottom and cannot be viewed.
[0028] The above-described solution of this utility model has at least the following beneficial effects:
[0029] This invention, by setting an auxiliary device, enables the detachable pantograph to be installed without requiring the operator to support it with their hands, thus reducing the labor intensity during installation and improving installation efficiency. This allows the operator to quickly complete the assembly and put the device into use.
[0030] This invention, by setting up an adsorption device, can restrict the position of the pneumatic base itself when connecting it to the electric locomotive, preventing it from moving. This makes it easier for operators to use tools to fix it, thus facilitating the connection operation between the pneumatic base and the electric locomotive. Attached Figure Description

[0037] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0038] like Figures 1 to 4 As shown, an embodiment of this utility model provides a detachable pantograph for electric locomotives, comprising:
[0039] Pneumatic base 1; Adjustment frame 2, mounted on the surface of pneumatic base 1 for linkage with pneumatic base 1; Threaded sleeve 3, threadedly connected to the surface of adjustment frame 2 for connecting adjustment frame 2 with other parts; Contact frame 4, rotatably connected to the surface of threaded sleeve 3 for assisting the electric vehicle in operation; Auxiliary device 5, set on the baffle surface of adjustment frame 2 for easy connection between threaded sleeve 3 and adjustment frame 2; Adsorption device 6, set on the surface of pneumatic base 1 for assisting in fixing pneumatic base 1 to the surface of electric vehicle.
[0040] like Figures 1 to 2As shown, the auxiliary device 5 includes two connecting seats 51, both of which are fixedly connected to the adjusting frame 2. A rod 52 is slidably connected to the surface of each connecting seat 51. A rectangular groove 55 is formed on the surface of each connecting seat 51. A ring 56 is rotatably connected to the surface of the threaded sleeve 3. A sliding plate 57 is fixedly connected to the surface of the ring 56. The size of the sliding plate 57 matches the rectangular groove 55. A circular hole 58 is formed on the surface of the sliding plate 57, the size of which matches the size of one end of the rod 52. The length of the sliding plate 57 is set to twice the length of the threaded sleeve 3. In use, the sliding plate 57 is aligned with the rectangular groove 55 and inserted into it until the threaded sleeve 3 approaches the threaded rod on the surface of the adjusting frame 2. At this point, the threaded sleeve 3 aligns with the contact frame 4 at the connection position of the adjusting frame 2. No manual support from the operator is required. Furthermore, the operator can rotate the threaded sleeve 3 to stably connect the adjusting frame 2 and the contact frame 4. The rod 52 can be inserted into the circular hole 58 for further positioning. A filler sleeve 54 is glued to the surface of the rod 52. The filler sleeve 54 is made of rubber and has an octagonal cross-section. The filler sleeve 54 can further fill the connection between the rod and the circular hole 58, and its special shape facilitates its entry into the circular hole 58. Two elastic ropes 53 are fixedly connected to the surface of the rod 52. The ends of the two elastic ropes 53 away from the rod 52 are fixedly connected to the connecting seat 51. When the slide plate 57 is placed, the rod 52 needs to be lifted. Due to the addition of the elastic ropes 53, the connection can be quickly achieved when the circular hole 58 and one end of the rod 52 are connected. Two limiting rods 59 are fixedly connected to the surface of the ring 56. Both limiting rods 59 are fixedly connected to the contact frame 4. The limiting rods 59 can limit the ring 56 when it is placed, so that it will not rotate when it is not in use.
[0041] In this embodiment of the utility model (working principle), first pull the insertion rod 52 upward to disengage it from the inside of the connecting seat 51, and then align the sliding plate 57 with the rectangular groove 55. At this time, the contact frame 4 can be easily limited. At the same time, the threaded sleeve 3 is connected to the threaded rod on the surface of the adjusting frame 2. The operator can then rotate the threaded sleeve 3. While the threaded sleeve 3 is connected to the adjusting frame 2, the sliding plate 57 will slide on the inner wall of the rectangular groove 55. When the threaded sleeve 3 drives the sliding plate 57 to move to the position where the insertion rod 52 is perpendicular to the circular hole 58, the insertion rod 52 will be reset by the action of the elastic rope 53 and will be tightly fixed inside the circular hole 58 with the filling sleeve 54, further improving the stability of the installation of the contact frame 4 and the adjusting frame 2.
[0042] like Figure 2 and Figure 4As shown, the adsorption device 6 includes two limiting seats 61, both of which are fixedly connected to the lower surface of the pneumatic base 1. Adhesive plates 62 are fixedly connected to the surfaces of both limiting seats 61. Sliding rods 64 are vertically slidably connected to the surfaces of both limiting seats 61. A suction cup 65 is fixedly connected to the end of the sliding rod 64 away from the limiting seat 61. Alternatively, the suction cup 65 can be a rubber suction cup or a PVC suction cup. A pressure plate 63 is slidably connected to the surfaces of both limiting seats 61. By pressing the suction cup 65 against the pressure plate 63, the pneumatic base 1 can be easily fixed to the surface of the locomotive. This allows operators to easily fix the pneumatic base 1 and the locomotive using threads or other parts. The device will not move. Four pull ropes 66 are fixedly connected to the surface of the pressure plate 63. The four pull ropes 66 are in pairs. The end of each pair of pull ropes 66 away from the pressure plate 63 is fixedly connected to the surface of the suction cup 65. When it is necessary to remove the suction cup 65 from the adsorption effect, the pressure plate 63 can be pulled upwards and then rotated. This causes the pressure plate 63 to work with the pull ropes 66 to lift the two sides of the suction cup 65, thereby removing it from the adsorption effect. Two auxiliary rods 67 are fixedly connected to the surface of the pressure plate 63. Both auxiliary rods 67 are "T" shaped. The auxiliary rods 67 make it easier for the operator to operate the pressure plate 63 and reduce the complexity of operation when the adsorption device 6 is at the bottom and cannot be viewed.
[0043] In this embodiment of the utility model, placing the hand on the auxiliary rod 67 and then pressing down on the driving pressure plate 63 can disengage the pressure plate 63 from the adhesive limit of the adhesive plate 62. This allows the suction cup 65 to be pressed, causing the suction cup 65 to slide along the inner wall of the limiting seat 61, thereby allowing the suction cup 65 to adhere to the surface of the locomotive and achieve the limiting effect. When it is necessary to replace the pneumatic base 1, the pressure plate 63 can be pulled upward by the auxiliary rod 67 and simultaneously swayed left and right. This allows the pressure plate 63, in conjunction with the pull rope 66, to lift the two sides of the suction cup 65, thereby disengaging the adhesive effect. The pneumatic base 1 can then be disassembled to complete the replacement.
[0044] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
