Specific embodiments

[0025] Next, embodiments of the technical solution of the present utility model will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, so they are only examples and cannot be used to limit the protection scope of the present utility model. The specific structure of the present utility model is as Figures 1-5 shown in.

[0026] Embodiment 1: A hydraulic winch for high-speed detection of tonnage, including a drum 1 with an internal reduction unit, a steel wire rope is wound around the outside of the drum 1, side plate stands 2 are symmetrically arranged on the left and right sides of the drum 1 respectively, the bottom of each side plate stand 2 is fixed on the top of a base 7 through a bolt set 4, the base 7 is fixedly installed on the top of a positioning seat 8 below it, the left and right ends of the drum 1 are respectively movably sleeved on the outer side walls of a left end bearing 5 and a right end bearing 6 at their respective corresponding positions on their corresponding sides, the left end bearing 5 and the right end bearing 6 are respectively fixed on the side plate stands 2 at the corresponding positions, a high-speed detection unit is arranged on the right side of the drum 1, the input end of the high-speed detection unit is connected to the output shaft 11 of a supporting power equipment, and the output end of the high-speed detection unit extends into the drum 1 for linkage with the internal reduction unit.

[0027] In the hydraulic winch of the present utility model, the whole relies on the drum 1 as the wire rope winding structure. During the operation of the whole winch, the end supports are realized by the side plate seat 2 at both ends. After the support, it is connected and installed on the base 7 by the bolt group 4, thereby ensuring the stability of the whole frame structure.

[0028] When the hydraulic winch needs to operate, the output shaft 11 of the external power equipment drives the high-speed detection unit and the built-in reduction unit of the drum 1 to operate, and finally achieves the purpose of the fixed-axis rotation of the whole drum 1 and lifting heavy objects; when the drum 1 is operating at high speed, relying on the high-speed detection unit can effectively monitor the high-speed torque measurement in its operating state, so as to obtain the analysis and calculation of the load tonnage in its high-speed state, and ensure the effective monitoring in the operating state.

[0029] In any of the above solutions, preferably, the high-speed detection unit includes a horizontally arranged high-speed torque measurer 20. The high-speed torque measurer 20 is fixed above the positioning seat 8 through the mounting frame 9. The left side of the high-speed torque measurer 20 is connected to a spline shaft 12 through a coupling 10. The right side of the high-speed torque measurer 20 is connected to the output shaft 11 of the power equipment through a coupling 10. The left end of the spline shaft 12 is integrally formed with a transmission gear 13. The transmission gear 13 extends into the drum 1 and is used to mesh with the corresponding components of the built-in reduction unit inside it. Among them, the high-speed torque measurer 20 is signal-connected to an external controller.

[0030] In the high-speed detection unit designed in the present utility model, during installation, the operation of the high-speed torque measurer 20 can drive the operation of the spline shaft 12. When the spline shaft 12 is operating, it can drive the gears of the built-in reduction unit inside the drum 1 through the transmission gear 13, thereby driving the drum 1 to rotate.

[0031] In any of the above solutions, preferably, the bolt group 4 includes a plurality of locking bolts 17 arranged at intervals in the front-back direction of the side plate seat 2. The inner ends of the locking bolts 17 all pass through the side plate seat 2 and are screwed into the corresponding threaded holes of the base 7. Plane parts 18 are respectively arranged at the top and bottom of the nut ends of the locking bolts 17. A disengagement prevention limiter is sleeved outside each of the locking bolts 17, and the inner side surface of the disengagement prevention limiter group is fixedly abutted against the surface of the side plate seat 2.

[0032] It should be noted that: when the bolt group 4 is installed, it relies on each locking bolt 17 to fixedly connect the side plate seat 2 and the base 7. When the disengagement prevention limiter is installed outside each locking bolt 17, it can play the role of disengagement prevention and limitation, thereby reducing the stability and firmness under the vibration conditions of high-speed operation.

[0033] Preferably, in any of the above solutions, the anti - detachment stopper includes a horizontally arranged metal limiting frame 21. The inner cavity of the metal limiting frame 21 is sleeved outside the nut ends of the locking bolts 17 in a matching manner. The side wall of the inner cavity of the metal limiting frame 21 abuts against the plane part 18 at the corresponding position of the nut end. The inner cavity of the metal limiting frame 21 is used to limit the rotation of each locking bolt 17. The upper part of the middle section of the metal limiting frame 21 is fixedly installed on the side plate stand 2 respectively.

[0034] When installing the anti - detachment stopper, it relies on the metal limiting frame 21 to be directly sleeved outside the nut ends of the locking bolts 17. Since the top and bottom of the nut end of the locking bolt 17 respectively adopt the plane part 18, it can directly abut tightly against the inner cavity of the metal limiting frame 21, so as to achieve the purpose of abutting and contacting tightly, and prevent the nut ends of the locking bolts 17 from rotating randomly.

[0035] Embodiment 2: Compared with Embodiment 1, the difference of this embodiment lies in that it further includes the following technical features:

[0036] Preferably, in any of the above solutions, a rope - pressing detector is arranged above the rear side of the drum 1.

[0037] Preferably, in any of the above solutions, the rope - pressing detector includes a positioning shaft 14 horizontally arranged outside the drum 1. The two ends of the positioning shaft 14 are respectively fixed on the side plate stand 2 at their corresponding positions. In the space between the positioning shaft 14 and the drum 1, multiple sections of rope - pressing components are arranged. The multiple sections of rope - pressing components are used to abut against the steel wire rope wound on the drum 1.

[0038] The rope - pressing detector serves the purpose of pressing the rope and detecting. Relying on each multiple - section rope - pressing component, it can directly contact the steel wire rope wound on the drum 1 and press it tightly, so as to achieve the purpose of pressing and limiting the rope.

[0039] Preferably, in any of the above solutions, the multiple sections of rope - pressing components include two connecting frames 15. A hollow rotating shaft 24 is fixedly installed between the two connecting frames 15. The two ends of the hollow rotating shaft 24 respectively penetrate through the corresponding connecting frames 15 and extend to the outside. Friction rope - pressing pipe sleeves 16 are respectively sleeved on the outer side wall of the hollow rotating shaft 24 between the two connecting frames 15 and on the outer side walls of the two ends of the hollow rotating shaft 24. The two ends of each friction rope - pressing pipe sleeve 16 are respectively installed on the outer side wall of the hollow rotating shaft 24 through built - in bearings 19 in a matching manner.

[0040] The multi-segment rope pressing component relies on two connecting frames 15 to position the entire hollow rotating shaft 24. After the positioning is completed, the two ends of the corresponding friction rope pressing tube sleeve 16 are supported by respective built-in bearings 19, so as to effectively achieve smooth rotation when rotating by relying on the friction force of the steel wire rope; multiple juxtaposed friction rope pressing tube sleeves 16 can effectively ensure the pressing of the entire steel wire rope and prevent it from jumping out of the rope groove.

[0041] In any of the above solutions, preferably, a rotational speed sensor 3 is installed in the annular cavity of the friction rope pressing tube sleeve 16 and the hollow rotating shaft 24. The detection ends of the rotational speed sensors 3 respectively abut against the inner walls of the friction rope pressing tube sleeves 16 at their corresponding positions. The outside of the friction rope pressing tube sleeve 16 is used to tightly press the steel wire rope. Each rotational speed sensor 3 is respectively signal-connected to an external controller through a signal wire 22 arranged in the central cavity 23 of the hollow rotating shaft 24.

[0042] Considering the monitoring of the running speed of the steel wire rope during the running process, multiple juxtaposed rotational speed sensors 3 are used here to detect the rotational speed of the friction rope pressing tube sleeve 16 in the rotating state, so as to achieve the purpose of quickly monitoring its running speed. When its rotational speed is too high, it can timely send the detected abnormal information, which is convenient for subsequent safety warning and improves the safety of the winch in the high-speed running state.

[0043] Specific working principle: The hydraulic winch as a whole relies on the drum 1 as the steel wire rope winding structure. When the entire winch works, it relies on the side plate seat 2 at both ends to achieve end support. After the support, it is connected and installed on the base 7 by a bolt unit 4, thereby ensuring the stability of the entire frame structure; when the hydraulic winch needs to operate, the output shaft 11 of an external power device drives the high-speed detection unit and the built-in reduction unit of the drum 1 to operate, and finally achieves the purpose of the entire drum 1 rotating around a fixed axis and lifting heavy objects.

[0044] When the drum 1 is running at high speed, the high-speed detection unit can effectively monitor the high-speed torque measurement in its running state, so as to obtain the analysis and calculation of the load tonnage in its high-speed state and ensure the effective monitoring in the running state. Among them, the high-speed detection unit can detect the load tonnage in the entire running state when the winch is running at high speed, effectively ensuring the safety of the winch during operation.

[0045] During operation, the rope pressing detector can detect the operating speeds of the drum 1 and the wire rope under high-speed rotation, effectively collect the transmission data related to the rotational speed, and ensure real-time monitoring of the operating parameters during the operation. Additionally, considering the safety of the entire structure under high-speed rotation, the anti-disengagement limiter is provided to effectively ensure the stable locking of each locking bolt 17, prevent it from rotating and falling off due to load vibration, and improve the stability of the support of the entire drum 1 during operation.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention; for those skilled in the art of this technology, any alternative improvement or transformation made to the embodiments of the present invention falls within the protection scope of the present invention.

[0047] The details not described in the present invention are all well-known technologies to those skilled in the art of this technology.
