DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] See also Figure 1-5 An embodiment of the present invention is as follows: a capstan device of a hydraulic traction machine for a crawler vehicle, comprising a base 1, a crawler mechanism is arranged below the base 1, so as to form a device of crawler vehicle shape, a capstan mechanism 2 and a retracting mechanism 3 are arranged above the base 1, respectively, the retracting mechanism 3 comprises a base frame 301, a guide assembly 302 and a reeling assembly 303, a lubrication box 4 is arranged above the guide assembly 302, an oil chamber 401 and a bottom groove 402 are arranged above and below the lubrication box 4, the oil chamber 401 is used to store lubricating oil, a cloth piece 7 is fixedly installed above the bottom groove 402 of the lubrication box 4, an oil delivery hole 403 is arranged inside the lubrication box 4 along the oil chamber 401 and the bottom groove 402, a sealing groove 404 and a translation cavity 405 are arranged along both sides of the oil delivery hole 403, a sealing plug 8 is arranged inside the translation cavity 405, one end of the sealing plug 8 passes through the oil delivery hole 403 and extends to the inside of the sealing groove 404.

[0018] When in use, the traction machine capstan device retracts and releases the wire rope and when the wire rope passes through the guide assembly 302, the wire rope passes through the bottom groove 402 of the lubrication box 4 and contacts the cloth piece 7. The lubricating oil in the oil chamber 401 flows down to the cloth piece 7 through the oil delivery hole 403, and then the lubricating oil is wiped onto the surface of the wire rope through the contact between the cloth piece 7 and the surface of the wire rope, thereby achieving lubrication and maintenance of the surface of the wire rope and reducing friction and wear of the wire rope during use. Lubrication and maintenance are performed by wiping, which avoids excessive oil on the surface of the wire rope and does not affect the normal operation of the capstan device.

[0019] See also Figure 1The capstan mechanism 2 includes a mounting plate 201, a capstan roller 1 202, a capstan roller 203 and a driving gear 204. The mounting plate 201 is fixedly connected to the base 1. The capstan rollers 1 202 and 203 are arranged vertically. The driving gear 204 is arranged on one side between the capstan rollers 1 202 and 203. The capstan rollers 1 202, 203 and the driving gear 204 are all rotatably connected to the mounting plate 201.

A hydraulic motor for the driving gear 204 is arranged at the rear end of the mounting plate 201, and an oil pumping mechanism of the hydraulic motor is arranged above the base, which is conducive to driving the driving gear 204 to rotate. The outer sides of the capstan rollers 1 202 and 203 are each provided with a plurality of capstan grooves.

[0020] Through the layout and connection method of the capstan roller 1 202, the capstan roller 203 and the driving gear 204 of the capstan mechanism 2, the capstan process is made more efficient and stable. By driving the driving gear 204 to rotate, the capstan roller 1 202 and the capstan roller 2 203 are driven to rotate, thereby achieving smooth traction and capstan of the wire rope. The setting of the capstan groove further enhances the capstan effect and improves work efficiency.

[0021] See also Figure 2 The base frame 301 is fixedly connected to the base platform 1, and the winding assembly 303 includes a winding frame 3031 and a side plate 3032.

A driving motor of the winding frame 3031 is provided on one side of the side plate 3032, and the side plate 3032 is fixedly connected to the base frame 301.

[0022] Through the combination of the winding frame 3031, the side plate 3032 and the driving motor of the winding assembly 303, the wire rope can be quickly and stably wound and released. This design not only improves the work efficiency, but also ensures the safety of the wire rope during the winding and releasing process. At the same time, the fixed connection between the side plate 3032 and the base frame 301 enhances the stability of the winding and releasing mechanism and extends its service life.

[0023] See also Figure 2 and Figure 3The guide assembly 302 includes a fixed housing 3021, a screw rod 3022, a guide rod 3023, a sliding block 3024, a side plate 3025 and a guide wheel 3026. The screw rod 3022 is configured as a reciprocating screw rod. The fixed housing 3021 is fixedly connected to the base frame 301. The screw rod 3022 is rotatably mounted inside the fixed housing 3021. A driving motor for the screw rod 3022 is disposed on one side of the fixed housing 3021. The guide rod 3023 is disposed on one side of the screw rod 3022 and It is fixedly connected to the fixed shell 3021, the sliding block 3024 is slidably installed on the outside of the screw rod 3022, and the guide rod 3023 slides through the sliding block 3024, two side plates 3025 are provided, and the two side plates 3025 are respectively fixedly installed on both sides of the sliding block 3024, the lubrication box 4 is fixedly connected to the side plate 3025, the upper end of the side plate 3025 extends to the top of the fixed shell 3021, and the guide wheel 3026 is rotatably installed above between the two side plates 3025.

[0024] The setting of the guide component 302 realizes the guidance and positioning of the wire rope through the combination of the reciprocating screw rod 3022, the guide rod 3023, the sliding block 3024 and the guide wheel 3026. By driving the screw rod 3022 to rotate, the sliding block 3024 is driven to slide back and forth along the guide rod 3023, thereby adjusting the position of the guide wheel 3026, so that the guiding wire rope can be evenly wound on the winding frame 3031, ensuring the stability of the wire rope during the winding and retracting process.

[0025] See also Figure 4 and Figure 5 An oil filling pipe 5 is fixedly installed above the lubrication box 4, and a pipe cover 6 is arranged above the oil filling pipe 5. A threaded rod 9 is rotatably installed on one side of the sealing plug 8. The threaded rod 9 is threadedly connected to the lubrication box 4. One end of the threaded rod 9 away from the sealing plug 8 extends to one side of the lubrication box 4 and is fixedly installed with a hand wheel 10 to facilitate the rotation of the threaded rod 9.

[0026] The provision of the oil filling pipe 5 and the pipe cover 6 makes the addition of lubricating oil more convenient and quick. At the same time, the combination of the sealing plug 8 and the threaded rod 9 ensures the sealing of the oil delivery hole 403 when lubrication is not required, thereby avoiding leakage and waste of lubricating oil.

[0027] Working principle: When in use, the capstan mechanism 2 above the base 1 uses a hydraulic motor to drive the driving gear 204 to rotate, thereby driving the capstan roller 1 202 and the capstan roller 203 to rotate synchronously, and the wire rope is smoothly pulled and efficiently capstanized through the capstan grooves on the outside of the capstan rollers. At the same time, the winding assembly 303 in the winding and unwinding mechanism 3 drives the side plates 3032 on both sides of the winding frame 3031 to rotate to realize the winding and unwinding of the wire rope. During the winding and unwinding process, the wire rope passes through the guide assembly 302 and is driven by the reciprocating screw rod. The movable sliding block 3024 slides along the guide rod 3023, and then adjusts the position of the guide wheel 3026 to ensure that the wire rope is evenly wound on the winding frame 3031. At the same time, the lubrication box 4 above the guide assembly 302 is provided with an oil chamber 401 and a bottom groove 402. The oil chamber 401 stores lubricating oil. When the wire rope passes through the cloth piece 7 in the bottom groove 402, the lubricating oil in the oil chamber 401 flows down to the cloth piece 7 through the oil delivery hole 403 and is wiped to the surface of the wire rope, thereby realizing automatic lubrication and maintenance and reducing friction and wear.
