Description

Technical Field

[0001] This invention belongs to the field of rescue equipment technology, specifically relating to a multi-station double winch towing rescue device. Background Technology

[0002] A rescue vehicle is used to pull and free vehicles that have broken down or become stuck in the ground. The common towing method used by rescue vehicles is to install a winch to pull the vehicle out of its stuck or immobile location. Currently, to ensure sufficient pulling power, rescue vehicles are often equipped with dual winches. This allows both winches to be activated simultaneously when the pulling power of a single winch is insufficient, increasing the rescue range. However, currently, the winches on rescue vehicles are often used solely for rescuing other vehicles, resulting in a relatively limited functional range for rescue vehicles. Summary of the Invention

[0003] This invention provides a multi-station dual winch towing and rescue device, which aims to solve the problem that the towing and rescue winch devices on rescue vehicles in the prior art have relatively limited performance.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a multi-station dual-winch rescue device, comprising:

[0005] The vehicle body is equipped with a support frame for supporting itself on the ground, and a first winch is installed on the support frame;

[0006] A second winch is installed on the vehicle body. A first hook is fixedly installed at the end of the rope on the second winch. The first hook is detachably installed at the front of the vehicle body.

[0007] The second hook is detachably mounted on the vehicle body. A guide wheel is rotatably mounted on the second hook, and the rope on the second winch is wound around the guide wheel.

[0008] In one possible implementation, the vehicle body is provided with a mounting bracket for installing the second hook, a guide post is fixedly installed on the second hook, and the mounting bracket is provided with a guide sleeve that slides with the guide post.

[0009] In one possible implementation, a positioning rod parallel to the guide sleeve is fixedly installed on the mounting bracket, a limit rod is slidably provided on the second hook, the end of the limit rod is provided with a guide wheel for abutting against the rope of the second winch, and a limit groove for accommodating the limit rod is provided on the outer wall of the positioning rod.

[0010] In one possible implementation, an elastic element for driving the limiting rod to move away from the positioning rod is further provided between the limiting rod and the second hook.

[0011] In one possible implementation, a limiting plate is fixedly installed on one end of the second hook away from the hook body, and a limiting hook for limiting the limiting plate on the mounting frame is hinged on the mounting frame. The mounting frame is also provided with a drive assembly for controlling the working state of the limiting hook.

[0012] In one possible implementation, the driving component includes:

[0013] The drive rod is rotatably mounted on the mounting bracket;

[0014] There are two connecting sleeves, which are threadedly connected to the drive rod and have opposite threaded holes inside. A hinge shaft is fixedly installed on the connecting sleeve, and an elongated through hole is provided on the limiting hook to slide with the hinge shaft.

[0015] In one possible implementation, a protective tube is also fixedly installed on the vehicle body, and the rope on the second winch passes through the second hook and is threaded inside the protective tube. The protective tube is provided with a limiting component for limiting the movement of the rope.

[0016] In one possible implementation, the limiting component includes:

[0017] The fixing block is fixedly installed inside the protective tube;

[0018] An extrusion block is slidably disposed on the protective tube along the radial direction of the protective tube, and the extrusion block and the fixing block form an installation space for accommodating the rope on the second winch;

[0019] A pushing component is disposed between the vehicle body and the extrusion block, for pushing the extrusion block to move toward the fixed block.

[0020] In one possible implementation, the pushing component includes:

[0021] A connecting rod is rotatably mounted on the vehicle body. A wedge block is threaded onto the connecting rod. The wedge block has an inclined surface for driving the extrusion block to slide closer to the fixed block. The extrusion block has a guide surface that slides in cooperation with the inclined surface.

[0022] In one possible implementation, the connecting rod is drive-connected to the drive rod.

[0023] The solution shown in this application, compared with the prior art, features a support frame that rotates at the rear of the vehicle body. This support frame, when unfolded, can support the vehicle body, facilitating the pulling of disabled or stuck vehicles. This application includes a first winch mounted on the support frame, which rotates with the support frame. A second winch is mounted on the vehicle body, and a second hook is detachably mounted at the rear of the vehicle body, while a first pull hook is mounted at the front. In use, the second pull hook can be detached from the rear of the vehicle body, and the first pull hook can be fixedly installed at the front. The second pull hook can then work with the first winch to pull the vehicle being rescued. When the rescue vehicle is stuck in the ground, the second pull hook can be fixed to the rear of the vehicle body, and the first pull hook can be detached from the vehicle body and connected to an object at the front. By activating the second winch, the vehicle can self-rescue, thus increasing the applicability of the rescue vehicle. Attached Figure Description

[0030] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0031] Please refer to the following: Figure 1 and Figure 2 The multi-position double winch rescue device provided by the present invention will now be described. The multi-position double winch rescue device includes a support frame 2 mounted on a vehicle body 1 for supporting the ground, and a first winch 3 mounted on the support frame 2; a second winch 4 mounted on the vehicle body 1, with a first hook 5 fixedly mounted at the end of the rope on the second winch 4, and the first hook 5 detachably mounted on the front of the vehicle body 1; and a second hook 6 detachably mounted on the vehicle body 1, with a guide wheel 61 rotatably mounted on the second hook 6, and the rope on the second winch 4 wound around the guide wheel 61.

[0032] The multi-station dual-winch towing device provided in this embodiment, compared with the prior art, features a support frame 2 rotatably mounted at the rear of the vehicle body 1. When unfolded, the support frame 2 can support the vehicle body 1 on the ground, facilitating the towing of disabled or stuck vehicles. This application includes a first winch 3 mounted on the support frame 2, rotating with it. A second winch 4 is mounted on the vehicle body 1, and a second hook is detachably mounted at the rear of the vehicle body 1. A first pull hook 5 is mounted at the front of the vehicle body 1. In use, the second pull hook 6 can be detached from the rear of the vehicle body 1, and the first pull hook 5 can be fixedly mounted to the front of the vehicle body 1. The second pull hook 6 can then work with the first winch 3 to pull the vehicle being rescued. When the rescue vehicle is stuck in the ground, the second pull hook 6 can be fixed to the rear of the vehicle body 1, and the first pull hook 5 can be detached from the vehicle body 1 and connected to an object in front of the vehicle body 1. By activating the second winch 4, the vehicle can perform self-rescue, increasing the applicability of the rescue vehicle.

[0033] Preferably, in this embodiment, when the rescue vehicle is at rest, the rope on the second winch 4 passes over the guide pulley 61 on the second hook 6 and is fixedly connected to the first hook 5. A mounting hole for installing the first hook 5 is provided at the front of the vehicle body 1, and the first hook 5 is fitted into the mounting hole.

[0034] In some embodiments, the vehicle body 1 may adopt the following... Figure 1 , Figure 2 and Figure 3 The structure shown. See also... Figure 1 , Figure 2 and Figure 3 The vehicle body 1 is equipped with a mounting bracket 11 for installing the second hook 6. A guide post 62 is fixedly installed on the second hook 6, and a guide sleeve 111 is provided on the mounting bracket 11 to slide with the guide post 62. The mounting bracket 11 is also fixedly installed at the rear of the vehicle body 1, and the guide sleeve 111 is fixedly installed on the mounting bracket 11. At least two guide posts 62 are fixedly installed on the second hook 6. These guide posts guide the second hook 6 to be installed onto the mounting bracket 11. Simultaneously, they improve the stability of the second hook 6 on the vehicle body 1 during movement.

[0035] Specifically, in this embodiment, the guide sleeve 111 is arranged along the length direction of the vehicle body 1.

[0036] In some embodiments, the mounting bracket 11 may be adopted as follows: Figure 1 , Figure 2 and Figure 3 The structure shown. See also... Figure 1 , Figure 2 and Figure 3 The mounting frame 11 is also fixedly mounted with a positioning rod 112 parallel to the guide sleeve 111. A limit rod 63 is slidably mounted on the second hook 6. The end of the limit rod 63 is provided with a guide wheel 631 for abutting against the rope of the second winch 4, and a limit groove for accommodating the limit rod 63 is provided on the outer wall of the positioning rod 112. The positioning rod 112 is fixedly mounted on the mounting frame 11, and a limit groove is recessed on the outer wall of the positioning rod 112. The limit rod 63 carries the guide wheel 631 and slides radially on the second hook 6. The axis of the guide wheel 631 is parallel to the axis of the guide wheel 61. There are two limit rods 63, located on both sides of the second hook 6. The rope on the second winch 4 is overlapped on the outside of the guide wheel 631. In use, the guide post 62 on the second hook body can be slid into the guide sleeve 111 first, and the second winch 4 can be started to wind up the rope. When the second winch 4 winds up the rope, it moves the second hook 6 closer to the mounting frame 11. Simultaneously, under the tension of the rope, the limiting rods 63 on both sides of the second hook 6 slide closer to the positioning rod 112, eventually sliding into the limiting groove to limit the position of the second hook 6. This operation is convenient and facilitates fixing the second hook 6 to the mounting frame 11.

[0037] Specifically, in this embodiment, the guide wheel 631 is rotatably mounted on the limiting rod 63.

[0038] Preferably, in this embodiment, a chamfer is provided inside the limiting groove to facilitate the sliding of the limiting rod 63. A guide surface parallel to the chamfer is provided at the end of the limiting rod 63. Thus, when the second hook 6 is pulled outward, the limiting rod 63 can be driven to move away from the positioning rod 112 by the guidance of the guide surface and the chamfer.

[0039] In some embodiments, the aforementioned limiting rod 63 may be adopted as follows: Figure 3 The structure shown. See also Figure 3An elastic element 64 is provided between the limiting rod 63 and the second hook 6 to drive the limiting rod 63 to move away from the positioning rod 112. The elastic element 64 is a spring, which is sleeved on the outside of the limiting rod 63. A mounting frame for sliding the limiting rod 63 is provided on the second hook 6, and a limiting platform is provided on the side wall of the limiting rod 63. One end of the elastic element 64 abuts against the limiting platform, and the other end abuts against the inner wall of the mounting frame near the positioning rod 112. The elastic element 64 reduces the force of the rope on the guide wheel 631 when the second winch 4 releases the rope. Thus, driven by the elastic element 64, the limiting rod 63 moves away from the positioning rod 112, causing the limiting rod 63 to disengage from the limiting groove. Therefore, when it is necessary to remove the second hook 6, the second winch 4 must first perform a rope release operation. After the rope release operation of the second winch 4 is completed, the limit rod 63 can automatically disengage from the limit groove, thereby removing the second hook 6 from the mounting bracket 11.

[0040] Specifically, in this embodiment, a push rod is slidably mounted on the mounting bracket 11. The push rod passes through the mounting bracket 11, and its length direction is along the axis of the guide sleeve 111. A spring is fitted on the push rod, with one end abutting against the mounting bracket 11 and the other end abutting against the end of the push rod located on the side of the mounting bracket 11 near the second hook 6, thereby pushing the push rod against the second hook 6. After the limiting rod 63 disengages from the limiting groove, the second hook 6 can be automatically moved outward by the drive of the push rod.

[0041] In some embodiments, the second hook 6 described above can be as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 A limiting plate 65 is fixedly mounted on the second hook 6 at one end away from the hook body. A limiting hook 113 is hinged on the mounting frame 11 to limit the limiting plate 65 on the mounting frame 11. The mounting frame 11 is also provided with a drive assembly 7 for controlling the working state of the limiting hook 113. The limiting plate 65 is fixedly mounted on the second hook 6. The limiting plate 65 can abut against the end of the guide sleeve 111 or the mounting frame 11, and the limiting hook 113 is hinged on the mounting frame 11. There are at least two limiting hooks 113, and the two or more limiting hooks 113 are respectively used to install on two or more opposite sides of the limiting plate 65. The limiting hook 113 rotates on the mounting frame 11 and the hook body of the limiting hook 113 can hook onto the end face of the limiting plate 65, thereby fixing the limiting plate 65. When the limiting hook 113 rotates away from the end face of the limiting plate 65, the second hook 6 can be pulled out from the mounting frame 11. This completes the installation and removal of the second hook 6, making the second hook 6 more stable on the mounting bracket 11.

[0042] In some embodiments, the driving component 7 described above may employ, for example... Figure 2 The structure shown. See also Figure 2 The drive assembly 7 includes a drive rod 71 and connecting sleeves 72. The drive rod 71 is rotatably mounted on the mounting bracket 11. There are two connecting sleeves 72, which are threadedly connected to the drive rod 71, and the threaded holes inside the two connecting sleeves 72 rotate in opposite directions. A hinge shaft is fixedly mounted on the connecting sleeve 72, and a limit hook 113 is provided with an elongated through hole that slides with the hinge shaft. The hinge shaft of the limit hook 113 on the mounting bracket 11 is located between the elongated through hole and the hook body on the limit hook 113. The drive rod 71 is rotatably mounted on the mounting bracket 11, and the axis of the drive rod 71 is perpendicular to the axis of the limit hook 113 on the mounting bracket 11. External threads with opposite rotation directions are provided at both ends of the drive rod 71. The connecting sleeves 72 are threadedly connected to the external threads of the drive rod 71. When the drive rod 71 rotates, the two connecting sleeves 72 move in a direction that is relatively closer or farther away, thereby driving the limit hook 113 to rotate on the mounting bracket 11. The two limit hooks 113 can be moved synchronously by driving the drive rod 71 to rotate. And the two limit hooks 113 are simultaneously located on two opposite sides of the mounting bracket 11.

[0043] In some embodiments, the vehicle body 1 may adopt the following... Figure 2 , Figure 4 The structure shown. See also... Figure 2 , Figure 4 A protective tube 8 is also fixedly installed on the vehicle body 1. The rope on the second winch 4 passes through the second hook 6 and then runs through the inside of the protective tube 8. A limiting component 9 is provided on the protective tube 8 to limit the movement of the rope. Installing the protective tube 8 on the vehicle body 1 reduces contact between the rope and the vehicle body 1, and also reduces dust falling onto the rope. The limiting component 9 on the protective tube 8 prevents the rope from moving. The limiting component 9 confines the rope inside the protective tube 8, allowing the rope to be fixed to the vehicle body 1 when the second hook 6 and the first winch 3 are operating synchronously. This prevents the rope from being stressed on the vehicle body 1 and affecting the strength of the front of the vehicle body 1, thus enhancing stability during operation.

[0044] In some embodiments, the limiting component 9 described above can be as follows: Figure 4 The structure shown. See also Figure 4The limiting component 9 includes a fixing block 91, a pressing block 92, and a pushing component 93. The fixing block 91 is fixedly installed inside the protective tube 8; the pressing block 92 is slidably disposed on the protective tube 8 along its radial direction, and the pressing block 92 and the fixing block 91 form an installation space for accommodating the rope on the second winch 4; the pushing component 93 is disposed between the vehicle body 1 and the pressing block 92, and is used to push the pressing block 92 towards the fixing block 91. The fixing block 91 is fixedly installed at the bottom of the inner wall of the protective tube 8, and the pressing block 92 is located above the fixing block 91. The rope on the second winch 4 is located between the fixing block 91 and the pressing block 92. By pushing the pressing block 92 towards the fixing block 91 using the pushing component 93, the rope is limited between the fixing block 91 and the pressing block 92, thus completing the rope fixation.

[0045] Preferably, in this embodiment, an anti-slip pad is provided on the opposite side of the fixing block 91 and the pressing block 92.

[0046] Preferably, in this embodiment, a pressure plate is slidably disposed on the side of the extrusion block 92 near the fixing block 91, and the pressure plate has the degree of freedom to slide on the extrusion block 92 toward or away from the fixing block 91. Furthermore, a spring is provided between the extrusion block 92 and the pressure plate for driving the pressure plate to move toward the fixing block 91.

[0047] In some embodiments, the aforementioned actuating component 93 may employ, as follows: Figure 4 The structure shown. See also Figure 4 The pushing component 93 includes a connecting rod 931 and a wedge block 932 disposed on the connecting rod 931. The connecting rod 931 is rotatably mounted on the vehicle body 1, and the wedge block 932 is threadedly connected to the connecting rod 931. The wedge block 932 is provided with an inclined surface for driving the extrusion block 92 to slide closer to the fixed block 91, and the extrusion block 92 is provided with a guide surface that slides with the inclined surface. A connecting arm is fixedly mounted on the wedge block 932 and is threadedly connected to the connecting rod 931. When the connecting rod 931 rotates, the wedge block 932 slides along the length of the connecting rod 931 on the vehicle body 1. The connecting rod 931 is driven to rotate by a motor. When the connecting rod 931 rotates, the wedge block 932 can move closer to or away from the extrusion block 92, and is guided by the inclined surface and the guide surface to drive the extrusion block 92 to move closer to the fixed block 91.

[0048] Preferably, in this embodiment, a spring is also provided between the extrusion block 92 and the protective tube 8 for driving the extrusion block 92 to move away from the fixed block 91.

[0049] In some embodiments, the connecting rod 931 and the drive rod 71 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 The connecting rod 931 is connected to the driving rod 71 via a transmission. The connecting rod 931 and the driving rod 71 are arranged perpendicularly to each other and are connected by a bevel gear transmission. In this embodiment, the connecting rod 931 is driven to rotate by a motor. When the connecting rod 931 drives the wedge block 932 to drive the pressing block 92 to move closer to the fixed block 91, the driving rod 71 rotates synchronously and drives the two connecting sleeves 72 on the driving rod 71 to move along the axis of the driving rod 71. The connecting sleeves 72 drive the limiting hook 113 to disengage from the limiting plate 65. At this time, the second hook 6 can be removed from the vehicle body 1, so that the first winch 3 and the second winch 4 can work simultaneously. Conversely, when the connecting rod 931 rotates in the opposite direction, the wedge block 932 can move away from the pressing block 92, and the pressing block 92 moves away from the fixed block 91 under the action of the spring. At the same time, the driving rod 71 drives the connecting sleeves 72 to move in the opposite direction, and the limiting hook 113 fixes the limiting plate 65 on the second hook 6 to the mounting bracket 11. At this point, the first hook 5 can be detached to rescue the vehicle body 1 itself. The operation is simple, and multiple workstations can work simultaneously, reducing the chance of errors, saving on the number of drive components, and saving costs.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
