Description

Technical Field

[0001] The utility model relates to the technical field of pantographs, in particular to a device for collecting and alarming the angle of a pantograph arm. Background Art

[0002] The single-arm pantograph, also known as the zigzag pantograph, has the advantage of being quieter than the double-arm pantograph and less likely to tear the contact network apart in the event of a fault. It is a more common type of pantograph. Depending on the design methods of each railway vehicle manufacturer, there will be some differences in the design of the pantograph.

[0003] The traditional pantograph does not have the ability to collect angles when adjusting the angle, and it is also unable to perform alarm processing after the angle collection is completed. Therefore, we propose an alarm device for collecting the angle of the pantograph arm. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a pantograph arm angle collection and alarm device, which has the advantages of timely alarm and good protection, and solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a device for collecting and alarming the arm angle of a pantograph, comprising a bracket, a connecting rod is fixedly installed on the outer wall of the bracket, the inner wall of the connecting rod is rotatably connected to a rotating shaft, a carbon slide is fixedly installed on the top of the connecting rod, a shell is fixedly installed on the outer wall of the connecting rod, a self-locking component is provided on the outer wall of the shell, a round rod is fixedly installed on the inner wall of the shell, the inner wall of the round rod is rotatably connected to a rotating plate, the inner wall of the shell is provided with a protective component, and a connecting shaft is fixedly installed on the outer wall of the rotating plate.

[0006] As a preferred technical solution of the utility model: the outer wall diameter of the rotating plate is matched with the inner wall diameter of the shell, and a sealing strip is fixedly installed on the outer wall of the rotating plate on one side close to the shell.

[0007] As a preferred technical solution of the utility model: the self-locking component includes a fixed plate, a circular shaft is fixedly installed on the inner wall of the fixed plate, a clamping plate is rotatably connected to the outer wall of the circular shaft, and a limiting block is fixedly installed on the top of the clamping plate.

[0008] As a preferred technical solution of the utility model: the outer wall of the fixing plate is fixedly mounted on the outer wall of the shell, and the outer wall of the clamping plate is in contact with the outer wall of the connecting shaft.

[0009] As a preferred technical solution of the utility model: the protective component includes a cylinder, a baffle is fixedly installed on the outer wall of the cylinder, a circular plate is provided on the outer wall of the cylinder, a connecting column is fixedly installed on the bottom of the circular plate, a signal generator is fixedly installed on the top of the circular plate, a fixing column is fixedly installed on the top of the cylinder, a top plate is fixedly installed on the top of the fixing column, and a signal receiver is fixedly installed on the outer wall of the top plate on one side close to the baffle.

[0010] As a preferred technical solution of the utility model: the positions of the baffle and the signal generator are parallel, the outer wall of the connecting column is fixedly installed with the outer wall of the connecting rod, there are six groups of signal receivers, and the six groups of signal receivers are evenly distributed on the outer wall of the top plate, and the bottom of the cylinder is fixedly installed with the top of the rotating shaft.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The arm angle collection and alarm device of the pantograph is fixedly installed through the bottom of the cylinder and the top of the rotating shaft. When the rotating shaft is rotating, the cylinder is also driven to rotate. When it rises to a normal angle, the light emitted by the signal generator can be blocked by the baffle. At this time, the signal receiver cannot receive the light emitted by the signal generator. When the rotation angle of the rotating shaft is too large, the baffle and the signal generator are misaligned, so that the light emitted by the signal generator is irradiated to the outer wall of the signal receiver. At this time, the signal receiver receives the signal, so that the signal receiver can directly alarm. At this time, the rotation angle of the rotating shaft has exceeded or fallen below the normal state, which will cause the problem of the carbon slide plate being detached from the wire.

[0013] 2. The arm angle collection and alarm device of the pantograph is connected with a rotating plate through the outer wall of the round rod. When the connecting shaft is pulled, the connecting shaft can drive the rotating plate to rotate on the outer wall of the round rod. At this time, the outer shell, the round rod and the rotating plate can protect the protective component to prevent the protective component from being blown down by strong wind during fast driving. When the protective component needs to be inspected and maintained regularly, the limit block is pulled so that the limit block can drive the clamping plate to rotate on the outer wall of the round shaft. At this time, the clamping plate can be lifted up so as to fix the outer wall of the plate. At this time, the connecting shaft that was originally in contact with the outer wall of the clamping plate can be removed. At this time, the connecting shaft can drive the rotating plate, so that the rotating plate can be opened on the outer wall of the outer shell. At this time, personnel can inspect the protective component to ensure that the protective component can alarm in time when there is a problem. BRIEF DESCRIPTION OF THE DRAWINGS

When the connecting shaft 9 is pulled, the connecting shaft 9 can drive the rotating plate 10 to rotate on the outer wall of the round rod 6. At this time, personnel can inspect and repair the protective component 8 to avoid damage to the protective component 8 and the inability to report the fault. At this time, the outer shell 5, the round rod 6 and the rotating plate 10 can protect the protective component 8 to prevent the protective component 8 from being blown down by strong wind during fast driving.

[0026] In the above structure, a sealing strip is fixedly installed on the outer wall of one side of the rotating plate 10 close to the outer shell 5. When the outer shell 5 is used for a long time and encounters rainy or snowy days, the sealing between the rotating plate 10 and the outer shell 5 can reduce the amount of rainwater entering the inner cavity of the outer shell 5, thereby avoiding damage to the protective component 8.

[0027] In a preferred embodiment, the self-locking assembly 7 includes a fixed plate 701 , a circular shaft 702 is fixedly mounted on the inner wall of the fixed plate 701 , a clamping plate 703 is rotatably connected to the outer wall of the circular shaft 702 , and a limiting block 704 is fixedly mounted on the top of the clamping plate 703 .

At this time, the clamping plate 703 can lift up the outer wall of the fixed plate 701. At this time, the connecting shaft 9 that was originally in contact with the outer wall of the clamping plate 703 can be removed. At this time, the connecting shaft 9 can drive the rotating plate 10, so that the rotating plate 10 can be opened on the outer wall of the shell 5.

[0030] In a preferred embodiment: the protective component 8 includes a cylinder 801, a baffle 802 is fixedly installed on the outer wall of the cylinder 801, a circular plate 803 is provided on the outer wall of the cylinder 801, a connecting column 805 is fixedly installed on the bottom of the circular plate 803, a signal generator 804 is fixedly installed on the top of the circular plate 803, a fixing column 806 is fixedly installed on the top of the cylinder 801, a top plate 807 is fixedly installed on the top of the fixing column 806, and a signal receiver 808 is fixedly installed on the outer wall of the top plate 807 on one side close to the baffle 802.

[0032] In the above structure, the bottom of the cylinder 801 is fixedly installed with the top of the rotating shaft 3. When the rotating shaft 3 rotates, the cylinder 801 is also driven to rotate. When it rises to a normal angle, the light emitted by the signal generator 804 can be blocked by the baffle 802. At this time, the signal receiver 808 cannot receive the light emitted by the signal generator 804. When the rotation angle of the rotating shaft 3 is too large, the baffle 802 and the signal generator 804 are misaligned, so that the light emitted by the signal generator 804 is irradiated to the outer wall of the signal receiver 808. At this time, the signal receiver 808 receives the signal, so that the signal receiver 808 can directly alarm.

[0033] Working principle: By pulling the limit block 704, the limit block 704 can drive the clamping plate 703 to rotate on the outer wall of the circular shaft 702. At this time, the clamping plate 703 can be lifted up so that the outer wall of the fixed plate 701 can be lifted up. At this time, the connecting shaft 9 that was originally in contact with the outer wall of the clamping plate 703 can be removed.

At this time, the personnel can inspect and repair the protective component 8 to avoid damage to the protective component 8. The bottom of the signal generator 804 is fixedly installed with the top of the rotating shaft 3. When the rotating shaft 3 is rotating, the cylinder 801 is also driven to rotate. When it rises to a normal angle, the light emitted by the signal generator 804 can be blocked by the baffle 802. At this time, the signal receiver 808 cannot receive the light emitted by the signal generator 804. When the rotation angle of the rotating shaft 3 is too large, the baffle 802 and the signal generator 804 are misaligned, so that the light emitted by the signal generator 804 is irradiated to the outer wall of the signal receiver 808. At this time, the signal receiver 808 receives the signal, so that the signal receiver 808 can directly alarm.
