Description

Technical Field

[0001] The utility model relates to the technical field of track inspection instruments, in particular to a manual turnout clutch for a track inspection instrument. Background Art

[0002] With the rapid development of China's rail transit industry, track inspection equipment has been widely popularized, and higher technical requirements have been put forward at the same time. Due to its ability to measure track geometric parameters such as gauge, superelevation, alignment, verticality, and twist (cross level) during the pushing process, the track inspection instrument is very popular among on-site workers and is the most widely used inspection equipment on site.

[0003] Since the measuring wheel of the track inspection instrument needs to be close to the inner top surface of the rail head at a position 16 mm below during the pushing inspection process, when passing through a turnout, the measuring wheel will get stuck in the harmful space of the turnout, causing damage to the parts of the track inspection instrument. Therefore, at present, when the track inspection instrument is pushed through a turnout, it is manually lifted to avoid the turnout and then the measurement starts again, which greatly increases the work intensity of the inspection personnel. Therefore, improvement is needed. Summary of the Utility Model

[0004] Based on this, in view of the above problems, it is necessary to provide a manual turnout clutch for a track inspection instrument.

[0005] A manual turnout clutch for a track inspection instrument includes a track inspection instrument, and also includes a handle, a torsion spring, a base, a clutch wheel, a rotating shaft, a cover and an extension rod. The base is detachably connected to the track inspection instrument. The base is hollow. The cover covers the port of the base. The rotating shaft is movably inserted into the base. The upper end of the rotating shaft protrudes outside the cover. The torsion spring and the clutch wheel are sequentially sleeved on the rotating shaft from bottom to top. One end of the extension rod is connected to the upper end of the rotating shaft, and the other end of the extension rod is connected to the handle. One end of a rope is wound around the clutch wheel, and the other end of the rope extends out from the hollow of the side wall of the base.

[0006] Preferably, a fixing piece is arranged at the bottom of the base, and a bolt passes through the fixing piece and is connected to the track inspection instrument.

[0007] Preferably, the wheel surface of the clutch wheel is provided with a groove, and the rope is wound in the groove.

[0008] Preferably, a stepped platform is arranged in the base, and the clutch wheel is installed on the stepped platform.

[0009] Preferably, a stop ring is arranged in the middle of the rotating shaft, and the upper end surface of the stop ring is flush with the table surface of the stepped platform, and the torsion spring is arranged below the stop ring.

[0010] Preferably, a support is sleeved on the extension rod.

[0011] The advantages of the present utility model are as follows: When passing through a turnout, the handle is manually turned in advance to rotate the clutch wheel and retract the rope, thereby driving the measuring wheel to leave the contact with the side of the rail, enabling the track inspection instrument to pass through the turnout smoothly. After the track inspection instrument passes through the turnout, the handle is manually turned again to restore the contact between the measuring wheel and the side of the rail, and normal measurement continues. There is no need for manual lifting of the track inspection instrument to pass through the turnout, which reduces the labor intensity of the operator and improves the detection efficiency.

Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0017] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only and do not represent the only implementation manner.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art belonging to the technical field of the present utility model. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0019] Such as Figures 1 to 4As shown in the figure, a manual turnout clutch for a track inspection instrument includes a track inspection instrument 100, and further includes a handle 1, a torsion spring 2, a base 3, a clutch wheel 4, a rotating shaft 5, a cover 6 and an extension rod 7. The base 3 is detachably connected to the track inspection instrument 100. The base 3 is hollow. The cover 6 covers the port of the base 3. The rotating shaft 5 is movably inserted into the base 3. The upper end of the rotating shaft 5 protrudes outside the cover 6. The torsion spring 2 and the clutch wheel 4 are sequentially sleeved on the rotating shaft 5 from bottom to top. One end of the extension rod 7 is connected to the upper end of the rotating shaft 5, and the other end of the extension rod 7 is connected to the handle 1. One end of a rope 8 is wound around the clutch wheel 4, and the other end of the rope 8 extends out from the hollow part 31 on the side wall of the base 3. Specifically, in this embodiment, the turnout clutch is installed on the track inspection instrument 100. Through the turnout clutch, the measuring wheel (not shown in the figure) is driven to approach or move away from the side of the rail. The turnout clutch includes a handle 1, a torsion spring 2, a base 3, a clutch wheel 4, a rotating shaft 5, a cover 6 and an extension rod 7. Among them, the base 3 is detachably installed on the track inspection instrument 100, and specifically, bolt connection can be adopted. The base 3 is made of metal, with high structural strength and hollow in the middle, which is convenient for installing the rotating shaft 5. The upper end of the rotating shaft 5 penetrates through the cover 6 and even extends outside the base 3 and is connected to the extension rod 7. The handle 1 is connected to the extension rod 7, which is convenient for the operator to drive the rotation of the rotating shaft through the handle 1. A torsion spring 2 and a clutch wheel 4 are sleeved on the rotating shaft 5. The clutch wheel 4 is used to wind up the rope 8. It can be understood that one end of the rope 8 is connected to the clutch wheel 4, and the other end is connected to the measuring wheel (not shown in the figure). When the rope 8 is wound up by the clutch wheel 4, the measuring wheel can be driven to move away from the side of the rail. At this time, the user does work against the torsional force of the torsion spring 2. After passing through the turnout, when the measuring wheel needs to be re-abutted against the side of the rail, the user releases the handle 1 and the pin on it. Under the auxiliary action of the torsional force provided by the torsion spring 2, the rotating shaft 5 rotates in the reverse direction, driving the clutch wheel 4 to rotate in the reverse direction. After the rope 8 is slack, the measuring wheel can be re-abutted against the side of the rail under the action of an external force, such as the linear spring force applied by the spring cylinder, thus completing one retraction and release of the turnout. In this way, it is avoided that the operator carries the track inspection instrument 100 through the turnout, and there is no need to use an electric wheel retracting mechanism to wind up the rope, reducing the cost of the track inspection instrument.

[0020] As Figures 3 to 4 shown, a fixing piece 32 is provided at the bottom of the base 3, and a bolt 33 passes through the fixing piece 32 and is connected to the track inspection instrument 100. Specifically, by using the fixing piece 32, the bolt 33 can connect the base 3 and the track inspection instrument 100, which is convenient for disassembly and assembly.

[0021] As Figure 3 shown, the wheel surface of the clutch wheel 4 is provided with a groove 41, and the rope 8 is wound in the groove 41. Specifically, by using the groove 41 to wind up the rope 8, it is avoided that the rope 8 runs off during the winding process and winds outside the wheel surface of the clutch wheel 4.

[0022] As Figures 3 to 4As shown, a stepped platform 34 is provided inside the base 3, and the clutch wheel 4 is mounted on the stepped platform 34. Specifically, the stepped platform 34 can support the clutch wheel 4 to prevent the clutch wheel 4 from hanging in the air.

[0023] As Figure 3 shown, a stop ring 51 is provided in the middle of the rotating shaft 5. The upper end surface of the stop ring 51 is flush with the table surface of the stepped platform 34, and the torsion spring 2 is arranged below the stop ring 51. Specifically, the stop ring 51 is used to separate the torsion spring 2 from the clutch wheel 4, and at the same time, the stop ring 51 can prevent the torsion spring 2 from moving circumferentially along the rotating shaft 5.

[0024] As Figures 2 to 3 shown, a support 71 is sleeved on the extension rod 7, and the extension rod 7 movably passes through the support 71. The support 71 is used to straighten the extension rod 7 to prevent the extension rod 7 from deflecting when the handle 1 drives the extension rod 7 to rotate.

[0025] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
