Description

Technical Field

[0001] This utility model relates to the field of water rescue equipment technology, specifically to a lifting device for an active water rescue robot. Background Technology

[0002] Water rescue support cabins are typically set up in waterways to house and charge water rescue robots, ensuring that the robots can quickly and easily conduct water rescue operations.

[0003] Related technologies include water rescue support cabins that have already appeared on the market, such as the utility model patent with authorization announcement number CN217893168U (the same applicant as this case), which discloses a water rescue robot cabin. By setting up a movable cabin and cooperating with a lifting motor, it is possible to lift and release the water rescue robot, thereby completing the lifting and release of the rescue robot.

[0004] However, in actual use, the traction rope is prone to wear and tear on other components during lifting and lowering operations, which affects the service life of the traction rope. In addition, the part of the traction rope that pulls the salvage plate will shake during lifting and lowering operations, affecting the stability of the rescue and causing secondary panic among the rescuers. To solve the above problems, a lifting device for an active water rescue robot is proposed. Utility Model Content

[0005] In view of this, the present invention provides a lifting device for an active water rescue robot. The present invention provides wear-resistant protection for the upper part of the traction end of the traction rope through a protective plate, wear-resistant protection for the middle part of the traction rope through a protective sleeve, and finally limits the lower part of the traction rope through a telescopic sleeve, so as to prevent the traction rope from shaking too much during operation and causing the retrieval plate to sway wildly, thereby improving the stability of the retrieval plate during lifting and lowering, thus making the rescue equipment more stable during rescue.

[0006] To solve the above-mentioned technical problems, this utility model provides a lifting device for an active water rescue robot, including symmetrically arranged connecting bridges on a rescue boat. The connecting bridges are arranged in the left-right direction. Each connecting bridge has a lifting chamber on the side of its top closest to the center of the rescue boat. Each lifting chamber has a lifting component, and each lifting component includes a motor. A rotating shaft is set at the output end of the motor. Multiple rope-retrieving rollers are fixedly set on each rotating shaft. A traction rope is fixedly set on each rope-retrieving roller. Each traction rope passes through an opening at the bottom of the lifting chamber. A telescopic sleeve is set at the bottom of each opening. Each traction rope passes through the telescopic sleeve. A retrieval plate is set at the end of the traction rope away from the rope-retrieving roller.

[0007] The lifting cabins are all set along the axial direction of the connecting bridge. Each lifting cabin has a support plate in the upper part. The support plate is used to fix and install the positioning frame. The support plate is set along the axial direction of the lifting cabin.

[0008] Each support plate has multiple positioning frames on its top. These frames are used to install pulleys, thus providing them with fixed support. Each positioning frame contains a pulley for the sliding of the traction rope, reducing wear on the rope. Each pulley corresponds to its coaxial take-up roller.

[0009] Each positioning frame has a protective plate at its bottom near the opening. The protective plate is used to reduce the friction between the bottom of the traction rope and the support plate when the traction rope is pulled on the pulley, thereby improving the service life of the component. The top of the protective plate is arc-shaped to prevent wear on the traction rope.

[0010] Each rotating shaft has a bearing housing at its end. The bearing housing is used to fix the rotating shaft and prevent it from shaking during operation. Each bearing housing is fixed in the lifting chamber on the same side.

[0011] Each opening has a protective sleeve at the top. The protective sleeve is used to reduce the friction between the traction rope and the inner wall of the opening, thereby improving the service life of the component. The lower part of the protective sleeve is a hollow cylinder and the upper part is a hollow frustum shape.

[0012] Multiple positioning buckles are fixedly installed on both sides of the retrieval plate. The positioning buckles are welded inside the retrieval plate and are used to connect the traction rope to the retrieval plate. When the motor drives the rope winding roller to rotate, the traction rope is pulled on the pulley, which in turn pulls the retrieval plate connected to the bottom of the traction rope to raise and lower. Each positioning buckle corresponds to its coaxial traction rope. The positioning buckle adopts a hanging lug, and each positioning buckle is connected to its corresponding traction rope through a knot.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. The upper part of the traction rope is protected against wear by a protective plate, the middle part of the traction rope is protected against wear by a protective sleeve, and the lower part of the traction rope is limited by a telescopic sleeve. This prevents the traction rope from shaking too much during operation, which would cause the retrieval plate to sway wildly. This improves the stability of the retrieval plate when it is raised and lowered, thus making the rescue equipment more stable during rescue.

[0015] 2. The positioning frame is used to install pulleys, thereby providing fixed support for the pulleys. The pulleys are used for the sliding of the traction rope, reducing the wear of the traction rope and thus improving the service life of the components.

[0016] 3. The bearing housing is used to fix the rotating shaft and prevent it from shaking during operation. When the rotating shaft rotates on the bearing housing, the rope winding rollers installed on the rotating shaft can simultaneously and synchronously wind up the ropes, thereby stretching multiple traction ropes at the same time.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0025] like Figure 1-6As shown: This embodiment provides a lifting device for an active water rescue robot, including symmetrically arranged connecting bridges 101 on a rescue boat 100. The connecting bridges 101 are narrow and elongated V-shaped, with a sharp angle at their front ends to reduce water resistance. The connecting bridges 101 are arranged in a left-right direction. Each connecting bridge 101 has a lifting chamber 200 on its top side near the center of the rescue boat 100. The lifting chamber 200 is made of stainless steel and can be welded to the connecting bridge 101. Each lifting chamber 200 has an inspection door on one side. Each lifting chamber 200 contains a lifting assembly 300, which is used to lift the retrieval plate 400. Each lifting assembly 300 includes a motor 301, which drives a rotating shaft 302 to rotate. The rotating shaft 302, located at the output end of the motor 301, drives multiple rope-retracting rollers 303 to simultaneously wind up the rope. Multiple rope-retracting rollers 303 are fixedly mounted on each rotating shaft 302. The traction rope 304 is wound and unwound. Each winding roller is fixedly equipped with a traction rope 304. The traction rope 304 is used to pull the retrieval plate 400 to rise and fall. Each traction rope 304 has an opening 201 at the bottom of the lifting chamber 200. The opening 201 is used to connect the traction rope 304 through the lifting chamber 200 and the retrieval plate 400. Each opening 201 has a telescopic sleeve 202 at its bottom. The top of the telescopic sleeve 202 can be welded to the bottom of the lifting chamber 200. The telescopic port at the bottom of 202 fits against the upper surface of the retrieval plate 400. The telescopic sleeve 202 is used to prevent the traction rope 304 from swinging left and right when pulling the retrieval plate 400, and to limit the traction rope 304 during operation, so that the retrieval plate 400 is more stable when it is raised and lowered, and it is easier to rescue people who have fallen into the water. Each traction rope 304 passes through the telescopic sleeve 202. There is a retrieval plate 400 at the end of the traction rope 304 away from the rope take-up roller 303. The retrieval plate 400 is made of stainless steel and coated with anti-corrosion paint.

[0026] During use, the upper part of the traction end of the traction rope 304 is protected against wear by the protective plate 204, the middle part of the traction rope 304 is protected against wear by the protective sleeve 205, and the lower part of the traction rope 304 is limited by the telescopic sleeve 202 to prevent the traction rope 304 from shaking too much during operation and causing the retrieval plate 400 to sway randomly, thereby improving the stability of the retrieval plate 400 when it is raised and lowered, thus making the rescue equipment more stable during rescue.

[0027] This embodiment provides a lifting device for an active water rescue robot.

[0028] like Figure 2 , 3As shown in Figure 5: The lifting chambers 200 are all arranged along the axial direction of the connecting bridge 101. Each lifting chamber 200 has a support plate 203 in its upper half. The support plate 203 is welded and fixed to the corresponding lifting chamber 200 on the same side. The support plate 203 is used to fix the positioning frame 305. The support plates 203 are all arranged along the axial direction of the lifting chamber 200. Each support plate 203 has multiple positioning frames 305 on its top. The positioning frame 305 is in the shape of an inverted hollow U-shape. The bottom of the positioning frame 305 is connected and fixed to the support plate 203 by a pad and bolts. The positioning frame 305 is used to install pulleys 306, thereby fixing and supporting the pulleys 306. Each positioning frame 305 has a pulley 306. The pulley 306 is rotatably connected to the positioning frame 305. The pulley 306 is used for the sliding of the traction rope 304 to reduce the wear of the traction rope 304. Each pulley 306 corresponds to its coaxial winding roller 303.

[0029] Its effect is as follows: the support plate 203 is used to fix the positioning frame 305, the positioning frame 305 is used to install the pulley 306, thereby fixing and supporting the pulley 306. The pulley 306 is used for the sliding of the traction rope 304, reducing the wear of the traction rope 304 and thus improving the service life of the components.

[0030] like Figure 2 , 5 As shown: Each positioning frame 305 has a protective plate 204 at its bottom near the opening 201. The bottom of the protective plate 204 can be fixed to the support plate 203 by bolts. The protective plate 204 is used to reduce the friction between the bottom of the traction rope 304 and the support plate 203 when the traction rope 304 is pulled on the pulley 306, thereby improving the service life of the component. The top of the protective plate 204 is arc-shaped to prevent the traction rope 304 from wearing.

[0031] Its effect is that the protective plate 204 is used to reduce the friction between the bottom of the traction rope 304 and the support plate 203 when the traction rope 304 is pulled on the pulley 306, thereby improving the service life of the component.

[0032] like Figure 2 As shown: Each rotating shaft 302 is provided with a bearing seat 307 at its end. The bottom of the bearing seat 307 is fixed to the bottom of the lifting chamber 200 by bolts. The bearing seat 307 is used to fix the rotating shaft 302 and prevent the rotating shaft 302 from shaking during operation. Each bearing seat 307 is fixed in the lifting chamber 200 on the same side.

[0033] Its effect is as follows: the bearing seat 307 is used to fix the rotating shaft 302 and prevent the rotating shaft 302 from shaking during operation. When the rotating shaft 302 rotates on the bearing seat 307, the rope take-up roller 303 installed on the rotating shaft 302 can simultaneously and synchronously take up the rope, thereby stretching multiple traction ropes 304 at the same time.

[0034] like Figure 4 , 5 As shown: Each opening 201 has a protective sleeve 205 installed at the top. The protective sleeve 205 is inserted into the opening 201. The protective sleeve 205 and the bottom plate of the lifting chamber 200 can be glued together. The inner ring size of the protective sleeve 205 must be larger than the outer ring size of the traction rope 304. The protective sleeve 205 is used to reduce the friction between the traction rope 304 and the inner wall of the opening 201, thereby improving the service life of the components. The lower part of the protective sleeve 205 is a hollow cylinder and the upper part is a hollow frustum shape.

[0035] Its effect is that the protective sleeve 205 is used to reduce the friction between the traction rope 304 and the inner wall of the opening 201, thereby improving the service life of the component.

[0036] like Figure 1 , 4 As shown in Figure 6: Multiple positioning buckles 401 are fixedly installed on both the left and right sides of the salvage plate 400. The positioning buckles 401 are welded inside the salvage plate 400. The positioning buckles 401 are used to connect the traction rope 304 to the salvage plate 400. When the motor 301 drives the rope winding roller 303 to rotate, the traction rope 304 is pulled on the pulley 306, which in turn pulls the salvage plate 400 connected to the bottom of the traction rope 304 to move up and down. Each positioning buckle 401 corresponds to its coaxial traction rope 304. The positioning buckles 401 adopt a hanging ear, and each positioning buckle 401 is connected to its corresponding traction rope 304 through a knot.

[0037] Its effect is as follows: the positioning buckle 401 is used to connect the traction rope 304 to the salvage plate 400. When the motor 301 drives the rope winding roller 303 to rotate, the traction rope 304 is pulled on the pulley 306, which in turn pulls the salvage plate 400 connected to the bottom of the traction rope 304 to rise and fall, thereby pulling the person in distress on the salvage plate 400 out of the water.

[0038] Working principle: The motor 301 drives the rotating shaft 302 to rotate, which in turn drives multiple rope winding rollers 303 to simultaneously wind or unwind, thereby controlling the stretching or contraction of the traction rope 304. When the traction rope 304 is stretched, the retrieval plate 400 rises via the pulley 306; when the traction rope 304 is lowered, the retrieval plate 400 descends to perform the rescue operation. During the operation of the traction rope 304, the upper part of the traction end of the traction rope 304 is protected against wear by the protective plate 204, and the middle part of the traction rope 304 is protected against wear by the protective sleeve 205. Finally, the lower part of the traction rope 304 is limited by the telescopic sleeve 202 to prevent excessive shaking of the traction rope 304 during operation, which would cause the retrieval plate 400 to sway erratically, thereby improving the stability of the retrieval plate 400 during lifting and lowering, thus making the rescue equipment more stable during rescue operations.

[0039] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
