Description

[0002] The capstan is one of the most commonly used mechanical equipment in our power transmission line construction. It is widely used in various processes of our line construction, and its main task is traction operation. When the capstan is used for normal traction, due to some uncontrollable reasons, the traction rope wrapped around the capstan quickly withdraws in the opposite direction, causing the original traction rope "tight forward" to "relax and fall freely", which is called the phenomenon of running. If the phenomenon of running occurs, the capstan loses its function, and the traction rope will quickly withdraw, driving the axial line to move rapidly in the direction of the capstan. If the on-site personnel cannot dodge in time, it will cause harm to the on-site personnel or even death. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] See also Figures 1 to 6 , the self-locking device for preventing the traction rope 6 from running and wearing provided by the present invention is now described. The self-locking device for preventing the traction rope 6 from running and wearing comprises a base 1, two guide members, a brake wheel 9 and a first self-locking component; a mounting frame 3 is provided on the base 1, and an outer support plate 2 is provided on the outer side of the mounting frame 3; two guide members are respectively located on the front and rear sides of the mounting frame 3, and the guide member comprises two guide rollers 5 arranged at intervals along the longitudinal direction; a brake wheel 9 is arranged on the mounting frame 3, and the brake wheel 9 has inclined ratchets extending outward, and the inclined direction of the ratchets is at an obtuse angle to the positive moving direction of the traction rope 6; support members are arranged at intervals below the brake wheel 9, and the traction rope 6 is located between the brake wheel 9 and the support members; the first self-locking component comprises an extension rod 15 arranged coaxially with the brake wheel 9 and a fixed seat 17 arranged on the outer support plate 2, the extension rod 15 extends into the fixed seat 17, and the end of the extension rod 15 has an elastic bayonet 24; a stopper 23 is provided in the fixed seat 17, and the end of the stopper 23 in contact with the elastic bayonet 24 is an inclined surface.

[0035] Compared with the prior art, the self-locking device for preventing the traction rope 6 from running and wearing provided by the present invention is provided with a guide assembly, a mounting frame 3, and a guide assembly in sequence from front to back on the base 1, and the gap between the two guide rollers 5 of the guide assembly and the gap between the brake wheel 9 and the support member are all located in the same horizontal plane; the traction rope 6 is confined in the above-mentioned gap to maintain a horizontal state.

[0036] During movement, the brake wheel 9 and the traction rope 6 rub against each other, and ratchets are arranged on the outer side of the brake wheel 9, and the inclination direction of the ratchets is at an obtuse angle to the positive moving direction of the traction rope 6. When the traction rope 6 moves forward, the ratchets on the outer side of the brake wheel 9 are pressed against the outer side of the traction rope 6, and the tips of the ratchets fit against the outer side wall of the traction rope 6, and the brake wheel 9 rotates with the movement of the traction rope 6. When the traction rope 6 moves in the reverse direction, the tips of the ratchets on the outer side of the brake wheel 9 abut against and press against the traction rope 6 to reduce the speed of the reverse movement of the traction rope 6 or even stop it from moving.

[0037] The traction rope 6 is fitted with the outer side wall of the brake wheel 9 under the action of the support and the two guide components. When the traction rope 6 moves forward, the brake wheel 9 fits on the upper end of the traction rope 6 and rotates under the friction of the traction rope 6, and the elastic bayonet 24 at the end of the extension rod 15 connected to the brake wheel 9 slides along the inclined surface of the stopper 23. When the traction rope 6 moves in the reverse direction, the ratchet tip of the brake wheel 9 will generate a large friction force with the traction rope 6, and the brake wheel 9 will rotate in the reverse direction under the friction of the traction rope 6, and the extension rod 15 will also rotate in the reverse direction. During the rotation, the elastic bayonet 24 is stuck on the cross section between the stoppers 23; thereby preventing the extension rod 15 and the brake wheel 9 from rotating in the reverse direction; when the brake wheel 9 stops rotating, its ratchet tip will squeeze the traction rope 6, thereby generating a large pressure and resistance, reducing the speed of the reverse movement of the traction rope 6 until it stops moving in the reverse direction.

[0038] The self-locking device for preventing the traction rope 6 from running and wearing provided by the present invention, by arranging a guide component and a support member, makes the traction rope 6 fit against the outer side of the brake wheel 9, and by arranging an elastic pin 24 and a block 23 matched with the elastic pin 24 on the side of the brake wheel 9, it is ensured that the brake wheel 9 can only rotate in the forward direction; an inclined ratchet is arranged on the outer side of the unidirectional rotating brake wheel 9 to cooperate with reducing the resistance of the traction rope 6 when it moves forward and preventing the traction rope 6 from moving in the reverse direction; so as to overcome the problem that the traction rope 6 moves in the reverse direction too fast when it runs and wears, thereby achieving the purpose of reducing the moving speed of the traction rope 6, reducing the harm caused by running and wearing, and enhancing safety.

[0039] Optionally, the support member is a plate member, and a rubber friction layer is provided on the plate member, and the rubber friction layer is used to increase the friction between the traction rope 6 and the support member.

[0040] Optionally, the rotating shaft of the brake wheel 9 is mounted on the mounting frame 3 by means of a bearing, and the rotating shaft of the brake wheel 9 passes through the mounting frame 3. The end of the extension rod 15 is connected to the rotating shaft of the brake wheel 9 and is coaxially arranged with the rotating shaft.

[0041] In some possible embodiments, see Figure 5A baffle 25 and an extension seat 16 are provided at the end of the extension rod 15. A limiting groove for accommodating the elastic bayonet 24 is opened in the extension seat 16 along its axial direction. The notch of the limiting groove has a limiting step extending inwardly to prevent the elastic bayonet 24 from escaping.

[0042] One end of the extension rod 15 is connected to the rotating shaft of the brake wheel 9, and the other end of the extension rod 15 is provided with a baffle 25 and an extension seat 16, wherein the extension seat 16 is located on the side of the baffle 25 away from the brake wheel 9. The end of the extension seat 16 is provided with a limiting groove along its axial direction, and the limiting groove has an elastic bayonet 24 inside. The elastic bayonet 24 includes a spring that penetrates into the limiting groove and a bayonet that abuts against the end of the spring, one end of the bayonet is located inside the limiting groove, and the other end of the bayonet is located outside the limiting groove. A limiting step is provided at the notch end of the limiting groove, and the limiting step cooperates with the end of the bayonet close to the spring to prevent the bayonet from escaping from the limiting groove.

[0043] The thickness of the block 23 gradually increases from front to back along the rotation direction of the extension rod 15, and there is a cross section between two adjacent block 23. When the traction rope 6 moves forward, the brake wheel 9 drives the extension rod 15 to rotate forward, and the elastic bayonet 24 sequentially retracts and contracts along the inclined surface of the block 23; when the traction rope 6 moves reversely, the brake wheel 9 drives the extension rod 15 to rotate reversely, and the elastic bayonet 24 is limited to one side of the cross section of the block 23 to limit the rotation of the extension rod 15, thereby preventing the reverse rotation of the brake wheel 9 and the reverse movement of the traction rope 6.

[0044] In some possible embodiments, see Figure 5 A connecting groove is provided in the fixing seat 17, a stopper 23 is provided on the bottom surface of the connecting groove and extends toward the notch of the connecting groove, and an end surface of the stopper 23 facing the notch of the connecting groove is an inclined surface.

[0045] The fixing seat 17 has a connection groove, the depth direction of the connection groove is horizontal, and the notch of the connection groove faces one side of the extension rod 15. A stopper 23 is arranged on the bottom surface of the connection groove, and the thickness direction of the stopper 23 is consistent with the depth direction of the connection groove. The thickness of the stopper 23 gradually increases along the positive rotation direction of the extension rod 15, and the end surface of the stopper 23 facing the notch of the connection groove is an inclined surface, and the inclined surface is in contact with the end surface of the elastic bayonet 24.

[0046] Optionally, the baffle 25 is located outside the fixing seat 17, and the baffle 25 is annular, and the outer diameter of the baffle 25 is larger than the outer diameter of the fixing seat 17. The baffle 25 blocks the notch end of the connecting groove on the fixing seat 17, and is used to protect the elastic bayonet 24 and the stopper 23 in the connecting groove.

[0047] Optionally, there are multiple elastic latches 24 and multiple stoppers 23, and the multiple elastic latches 24 and the multiple stoppers are arranged in one-to-one correspondence.

[0048] In some possible embodiments, see Figure 1 , Figure 2 and Figure 4 The supporting member is a driven wheel 10, both ends of which are rotatably connected to the mounting frame 3, and the outer diameter of the driven wheel 10 gradually increases from the middle to both sides.

[0049] Specifically, the support member is a driven wheel 10 rotatably mounted on the mounting frame 3, the outer wall of the driven wheel 10 is smooth or uneven, and the outer diameter of the driven wheel 10 gradually increases from the middle to both sides, so that a recessed portion for accommodating the traction rope 6 is formed in the middle to prevent the traction rope 6 from horizontally moving along the axial direction of the driven wheel 10. The traction rope 6 is located in the recessed portion and fits on the outer wall of the brake wheel 9.

[0050] Optionally, the outer diameter of the brake wheel 9 gradually increases from the middle to both sides, and there is also a recess in the middle of the brake wheel 9. The recess of the brake wheel 9 cooperates with the recess of the driven wheel 10 to limit the horizontal movement of the traction rope 6 and ensure that the outer wall of the traction rope 6 can fit tightly with the outer wall of the brake wheel 9.

[0051] In some possible embodiments, see Figure 1 and Figure 2 The driven wheel 10 has inclined ratchet teeth extending outward in the circumference, the inclined direction of the ratchet teeth forms an obtuse angle with the positive moving direction of the traction rope 6, and the ratchet teeth are attached to the outer side wall of the traction rope 6.

[0052] Specifically, the structure of the driven wheel 10 is consistent with that of the brake wheel 9, and inclined ratchet teeth are also provided on the outer wall thereof. However, since the driven wheel 10 is located below the traction rope 6 and the brake wheel 9 is located above the traction rope 6, the inclination direction of the ratchet teeth of the driven wheel 10 and the inclination direction of the ratchet teeth of the brake wheel 9 are axially symmetrical, and the axis of symmetry is located in the horizontal plane where the axis center of the traction rope 6 is located.

[0053] Clockwise rotation is positive rotation, and counterclockwise rotation is negative rotation.

[0054] When the traction rope 6 moves forward, the brake wheel 9 rotates forward and the driven wheel 10 rotates reversely; when the traction rope 6 moves reversely, the brake wheel 9 rotates reversely and the driven wheel 10 rotates forward. When the brake wheel 9 rotates reversely and the driven wheel 10 rotates forward, the tooth tips of the ratchet teeth of the brake wheel 9 abut against the upper end of the traction rope 6, and the tooth tips of the ratchet teeth of the driven wheel 10 abut against the lower end of the traction rope 6, and the upper and lower sides of the traction rope 6 are squeezed by the ratchet teeth.

[0055] Optionally, a first self-locking device is also provided at both ends of the driven wheel 10, that is, an extension rod 15 and a fixed seat 17 are provided on the outer side of the driven wheel 10, and the driven wheel 10 cooperates with the elastic pin 24 on the extension rod 15 and the block 23 in the fixed seat 17 to achieve unidirectional rotation restriction of the driven wheel 10.
