[0001] The utility model relates to the technical field of testing power supply lines of electrified rail trains, in particular to a pantograph simulation device. Background Art

[0002] For electrified rail trains, the pantograph located on the top of the train needs to contact the power supply line on the top of the train to provide continuous power supply. If the power supply line is not installed properly, the train will not be able to be powered continuously. Utility Model Content

[0003] The utility model aims to provide a pantograph simulation device to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems is as follows: a pantograph simulation device, comprising: a base; a sliding rod, slidably arranged on the base; a spring, sleeved on the sliding rod, one end of the spring is connected to the outer periphery of the sliding rod, and the other end is connected to the base; a limit seat, installed on the sliding rod, one end of the spring is connected to the base and the limit seat clamps the base, and the spring provides elastic force to press the limit seat against the base; a simulation bow, installed on the end of the sliding rod.

[0005] This technical solution has at least the following beneficial effects: after the power supply line is installed, the simulated bow is moved away from one end face of the slide bar to contact the power supply line, and the elastic force of the spring is used to maintain the contact connection between the simulated bow and the power supply line, thereby simulating the working state of the pantograph on the top of the train. The line is tested by using this pantograph simulation device, which can be used to detect whether the line installation meets the design requirements and improve the standardization and reliability of the power supply line installation.

[0006] As a further improvement of the above technical solution, the limit seat is slidably arranged on the slide bar, and the limit seat is provided with a first fastener for fixing the limit seat and the slide bar relative to each other. By adjusting the position of the limit seat on the slide bar and fixing the adjusted position with the first fastener, the initial position of the slide bar is changed under the action of the spring, thereby achieving the adjustment of the initial height of the simulated bow and the adjustment of the contact force to meet different detection requirements.

[0007] As a further improvement of the above technical solution, an adjusting seat is slidably mounted on the sliding rod, one end of the spring away from the base is connected to the adjusting seat, and the adjusting seat is provided with a second fastener for relatively fixing the adjusting seat and the sliding rod. By changing the position of the adjusting seat on the sliding rod and fixing the changed position with the second fastener, the relative positions of both ends of the spring in the initial state can be adjusted without changing the height of the simulation bow, and further the contact force of the simulation bow in the initial state can be adjusted to meet different detection requirements.

[0008] As a further improvement of the above technical solution, the base includes a transverse plate and at least two support feet, wherein two of the support feet are respectively installed at both ends of the transverse plate, the sliding rod passes through the transverse plate, one end of the spring away from connecting the sliding rod is connected to the transverse plate, and the limiting seat and the spring clamp the transverse plate. The base is composed of the support feet and the transverse plate, and the overall structure is simple, which is convenient for processing and production.

[0009] As a further improvement of the above technical solution, the transverse plate includes two parallel transverse rods, the sliding rod passes through between the two transverse rods, the distance between the two transverse rods is adapted to the diameter of the sliding rod, and a support seat for the sliding rod to pass through is commonly installed between the two transverse rods. One end of the spring away from connecting the sliding rod is connected to the support seat, and the limiting seat and the spring clamp the transverse rod and the support seat. The structure is simple and stable, which is convenient for welding, processing and production.

[0010] As a further improvement of the above technical solution, a pressure sensor is installed at the position where the support seat is abutted by the spring, and the pressure sensor is used to measure the elastic force of the spring against the support seat. By measuring the elastic potential energy of the spring compression with the pressure sensor, the initial contact force of the simulation bow and the change of the contact force during the test process can be detected.

[0011] As a further improvement of the above technical solution, a detachable bolt is connected between the support foot and the transverse plate. Through the detachable connection of the bolt, it is convenient for disassembly, assembly and storage, and different sizes of each component can be combined as required to meet the needs of different detections.

[0012] As a further improvement of the above technical solution, connecting rods are arranged at both ends of the simulation bow, and a stabilizing rod parallel to the simulation bow is commonly connected to the two connecting rods on both sides, and the sliding rod slidably passes through the stabilizing rod. The stabilizing rod can guide the sliding rod, thereby improving the relative sliding stability between the simulation bow and the sliding rod and ensuring that the simulation bow has a high compressive capacity.

[0013] As a further improvement of the above technical solution, a quick-connect fixing clip is installed at the bottom of the base. So as to facilitate the quick fixing and disassembly of the whole.

[0014] As a further improvement of the above technical solution, an anti-collision pad is provided at one end of the limit seat that abuts against the base. Under the action of the restoring force of the spring, when the simulation bow returns to its initial state, the limit seat abuts against one end of the base, and the anti-collision pad can reduce the situation of the limit seat hitting the base, thereby reducing the loosening of the structures of various components caused by multiple impacts.

[0025] Refer to Figures 1-4 , the pantograph simulation device includes a base 100, a slide bar 200, a spring 300, a limit seat 400, and a simulation bow 500.

[0026] The base 100 includes a transverse plate 110 and two support feet 120. The two support feet 120 are symmetrically arranged with respect to the central plane of the transverse plate 110 at both ends of the transverse plate 110. The support feet 120 are integrally arranged in a U shape, and the U-shaped opening is arranged downward. The support feet 120 can be formed by welding three hollow square tubes or formed by bending a single hollow square tube into an integral structure. In other embodiments, the support feet 120 can also be formed by welding three hollow round tubes or formed by bending a single hollow round tube into an integral structure.

[0027] The transverse plate 110 includes two independently arranged transverse rods 111, and the transverse rods 111 are hollow square tubes. Threaded rods are penetrated through both ends of the transverse rods 111, and the ends of the threaded rods pass through the transverse rods 111 and the corresponding end support feet 120 and are fastened by screwing nuts. The threaded rods and the nuts form a detachable bolt 130, and this detachable bolt 130 can facilitate the installation and disassembly between the transverse rods 111 and the support feet 120, so as to facilitate the assembly and storage of the base 100. In other embodiments, both ends of the transverse rods 111 can also be directly fixed to the support feet 120 by welding. In other embodiments, both ends of the two transverse rods 111 can first form a square frame as a whole by jointly fixing a connecting block, and then both ends of the square frame are connected to the support feet 120 through the detachable bolt 130, which can also facilitate installation and disassembly, so as to facilitate the assembly and storage of the base 100.

[0028] Both ends of the U-shaped structure of the support foot 120 are arranged downward and are both equipped with quick-connection fixing clips 140. The quick-connection fixing clip 140 includes a first arc-shaped buckle and a second arc-shaped buckle. The first end of the first arc-shaped buckle is rotatably connected to the first end of the second arc-shaped buckle. A fixing rod is rotatably installed at the second end of the first arc-shaped buckle. A pressing block is threadedly connected to the fixing rod. A notch for the fixing rod to be inserted into is provided at the second end of the second arc-shaped buckle. A fixing column is installed on the side of the first arc-shaped buckle facing away from the second arc-shaped buckle. A fixing hole is provided at the end of the support foot 120. By inserting the fixing column into the fixing hole for installation, the first arc-shaped buckle can be fixed on the support foot 120. Then, the first arc-shaped buckle and the second arc-shaped buckle are clamped around the rod at the installation position. Then, rotate the fixing rod to insert it into the notch, and rotate the pressing block to the position where it abuts against the second end of the second arc-shaped buckle, so that the first arc-shaped buckle and the second arc-shaped buckle tightly clamp the rod at the installation position, realizing quick installation. By loosening the pressing block to loosen the first arc-shaped buckle and the second arc-shaped buckle, quick disassembly can be realized.

[0029] In addition, in other embodiments, the number of the support feet 120 can also be evenly arranged in parallel in three, four or five. The two support feet 120 at the outermost ends are respectively located at both ends of the transverse plate 110, ensuring the support stability of the support feet 120 for the transverse plate 110. All the support feet 120 can be connected to the transverse rod 111 through detachable bolts 130. Quick-connection fixing clips 140 are installed at both ends of all the support feet 120.

[0030] Among them, the two transverse rods 111 are arranged in parallel and the gap distance between them is the same as the diameter of the sliding rod 200. Two sliding rods 200 are arranged side by side along the length direction of the transverse rod 111, and the two sliding rods 200 are parallelly distributed. The sliding rod 200 passes through the gap between the two transverse rods 111, so that the two transverse rods 111 can limit the positions on both sides of the sliding rod 200. Two support seats 112 are installed side by side along the length direction of the transverse rod 111 on the two transverse rods 111. The support seat 112 straddles the two transverse rods 111, that is, the two transverse rods 111 are installed at both ends of the support seat 112 through screws. The two sliding rods 200 are respectively arranged through the corresponding support seats 112, so that the sliding rod 200 is slidably connected to the support seat 112 in the vertical direction. Therefore, the support seat 112 can not only provide sliding limit for the sliding rod 200, but also be used to connect the two transverse rods 111. The structural design is ingenious and stable, and it is convenient for installation.

[0031] In other embodiments, the support seat 112 can be directly welded to the two transverse rods 111, so as to directly connect the two transverse rods 111 and save the trouble of assembly.

[0032] The sliding rod 200 passes through the gap between the support base 112 and the two transverse rods 111 from top to bottom in sequence. The limiting seat 400 is in an annular shape and sleeved on the bottom position of the sliding rod 200. The limiting seat 400 and the sliding rod 200 can move relatively slidably. The limiting seat 400 is at the bottom position of the transverse rod 111. The limiting seat 400 is also provided with a first fastener 410. The first fastener 410 is a first screw rod. The first screw rod is screwed into the limiting seat 400 and presses against the outer side wall of the sliding rod 200, so that the limiting seat 400 and the sliding rod 200 can be relatively fixed to fix the position of the limiting seat 400 on the sliding rod 200. Therefore, the position of the limiting seat 400 on the sliding rod 200 can be adjusted by loosening the first screw rod, and then the position of the adjusted limiting seat 400 can be fixed by tightening the first screw rod.

[0033] In other embodiments, a disconnected crack can also be opened on one side of the limiting seat 400, so that the limiting seat 400 is in an overall C-shaped structure. One end of the first screw rod is rotatably connected to one end of the limiting seat 400, and the other end of the first screw rod is threadedly connected to the other end of the limiting seat 400. By rotating the first screw rod, the two ends of the limiting seat 400 can be made to approach each other, and further the limiting seat 400 can be tightly fastened to the sliding rod 200, and the limiting seat 400 and the sliding rod 200 can also be relatively fixedly connected. In other embodiments, the number of the sliding rods 200 can also be arranged in parallel in three or four.

[0034] The simulation bow 500 is installed at the top positions of the two sliding rods 200. The simulation bow 500 and the transverse rod 111 are distributed in parallel. Both ends of the simulation bow 500 are respectively connected with a connecting rod 510. The two connecting rods 510 at both ends of the simulation bow 500 are inclined in the direction away from each other at the end far from the simulation bow 500. The two connecting rods 510 are commonly connected with a stabilizing rod 520 at the end far from the simulation bow 500. The stabilizing rod 520 is parallel to the simulation bow 500 and the stabilizing rod 520 is at the position close to the side of the transverse rod 111, so that the simulation bow 500, the two connecting rods 510 and the stabilizing rod 520 form a trapezoidal frame structure. The sliding rod 200 slidably passes through the stabilizing rod 520 and is detachably connected to the simulation bow 500 through a bolt 130, so that the connection stability between the sliding rod 200 and the simulation bow 500 can be improved. At the same time, it is also convenient for disassembly and assembly, so as to facilitate storage.

[0035] An adjusting seat 600 is provided between the sliding rod 200 and the stabilizing rod 520. The adjusting seat 600 is annular and sleeved on the sliding rod 200. The adjusting seat 600 is equipped with a second fastener 610. The second fastener 610 is a second screw rod. The second screw rod is screwed into the adjusting seat 600 and presses against the outer side wall of the sliding rod 200. Thus, the adjusting seat 600 and the sliding rod 200 can be relatively fixed to fix the position of the adjusting seat 600 on the sliding rod 200. Therefore, the position of the adjusting seat 600 on the sliding rod 200 can be adjusted by loosening the second screw rod, and then the position of the adjusted adjusting seat 600 can be fixed by tightening the second screw rod.

[0036] In other embodiments, a disconnected crack can also be opened on one side of the adjusting seat 600, so that the adjusting seat 600 is integrally in a C-shaped structure. One end of the second screw rod is rotatably connected to one end of the adjusting seat 600, and the other end of the second screw rod is threadedly connected to the other end of the adjusting seat 600. By rotating the second screw rod, the two ends of the adjusting seat 600 can be made to approach each other, and further the adjusting seat 600 can be tightened around the sliding rod 200. Similarly, the adjusting seat 600 and the sliding rod 200 can also be relatively fixedly connected.

[0037] The spring 300 is a helical spring. The spring 300 is sleeved on the outer circumference of the sliding rod 200. One end of the spring 300 abuts against the top of the support seat 112, and the other end abuts against the bottom of the adjusting seat 600. The elastic force of the spring 300 can lift the adjusting seat 600, thereby lifting the sliding rod 200, so that the top of the limit seat 400 presses against the bottom position of the transverse rod 111, that is, the bottom of the spring 300 and the limit seat 400 clamp the transverse rod 111 and the support seat 112. At this time, the simulation bow 500 is in the initial height position and has an initial elastic force. Optionally, an anti-collision pad is installed on the top of the limit seat 400. The anti-collision pad can be a rubber pad, which can prevent the situation that the overall structure is easily loosened due to the impact of the limit seat 400 on the bottom of the transverse rod 111 during the movement of the limit seat 400 along with the sliding rod 200.

[0038] When the length of the spring 300 is within the range shorter than the original length, by adjusting the position of the limit seat 400 on the sliding rod 200, since the limit seat 400 has always been in the position where its top abuts against the bottom of the transverse rod 111, the position of the sliding rod relative to the transverse rod 111 can be adjusted, thereby realizing the adjustment of the initial height position of the simulation bow 500. The adjustment of the initial height position will also be accompanied by the change of the initial elastic force. At this time, by further adjusting the position of the adjusting seat 600 on the sliding rod 200 and changing the distance between the adjusting seat 600 and the support seat 112, the length of the spring 300 can be adjusted to realize the adjustment of the initial elastic force to meet the test requirements under different conditions.

[0039] In other embodiments, the two ends of the spring 300 can be directly fixedly installed on the support seat 112 and the adjusting seat 600 respectively.

[0040] Optionally, a pressure sensor is installed on the support base 112, and the sensing end of the pressure sensor is located at the top of the support base 112 for the spring 300 to abut against, so that the pressure sensor can detect the compression elastic force of the spring 300. When the simulation bow 500 is in the initial state, the compression elastic force can represent the initial elastic force of the simulation bow 500. When the simulation bow 500 abuts against the power supply line, the compression elastic force can represent the contact force of the simulation bow 500 on the power supply line. Therefore, the pressure sensor can not only detect the initial elastic force of the simulation bow 500 to facilitate the adjustment of the position of the simulation bow 500 and the length of the spring 300, but also can detect the contact force of the simulation bow 500 on the power supply line in real time, understand the installation stability of the power supply line, and timely feedback installation problems, etc.

[0041] It should be noted that the pressure sensor can be equipped with a built-in display for displaying the pressure value parameter or the elastic force value converted from the pressure value parameter. The pressure sensor can also be directly or indirectly connected to an electronic device through wired or wireless communication methods, and the pressure value parameter or the elastic force value parameter can be observed through the display screen of the electronic device.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present invention.
