Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

Referring to fig. 1 to 4, a description will now be given of a large tonnage equipment dragging technique according to the present application. A large tonnage equipment dragging technique, comprising: the device comprises a frame body 1, a supporting roller 2, a getting rid of the trapping net, a traction wheel 3 and a positioning rope 5. The frame body 1 is used for being fixed on a vehicle body. The support roller 2 is mounted at the end of the bottom of the frame 1. The stranded net is wound on the supporting roller 2, and the end part of the stranded net, which is positioned at the outer side, is set to be the end part of the stranded net, which is positioned at the inner side, is set to be the tail end; the head end after unreeling is used for sliding to the bottom of the wheel by means of acting force when the wheel of the to-be-saved car rotates. The traction wheel 3 is arranged on the frame body 1, and the traction wheel 3 is positioned above the supporting roller 2. A positioning rope 5 is bolted between the traction wheel 3 and the head end. The traction wheel 3 rotates and winds the positioning rope 5, so that the head end moves upwards from the bottom of the wheel to enable the escape net to support the wheel of the rescue vehicle.

The large-tonnage equipment supporting and pulling technology provided by the application has the beneficial effects that: compared with the prior art, in the large-tonnage equipment supporting and pulling technology, the frame body 1 is fixed on the vehicle body, the support roller 2 is arranged at the tail end of the bottom of the frame body 1, the escape net is wound on the support roller 2, and the head end and the tail end are arranged on the escape net. A traction wheel 3 is arranged on the frame body 1, and the traction wheel 3 is positioned above the supporting roller 2. A positioning rope 5 is bolted between the head end and the traction wheel 3.

In the practical application process, the support roller 2 rotates to enable the stranded net to be unreeled, and after the stranded net is unreeled, the head end can slide to the bottom of the wheel under the condition that the wheel of the to-be-saved vehicle rotates. At this time, the positioning rope 5 is pulled by the traction wheel 3, so that the height of the head end of the positioning rope 5 is increased, the escape net can support wheels, and at this time, the traction of the to-be-saved vehicle can be realized under the traction action of the vehicle body. The application can effectively support the wheels, and the whole process does not need staff to bolt the traction hooks, so that the rescue and repair efficiency is improved, and the application range is widened.

Before rescue, the extension rope 4 and the escape net are wound on the support roller 2, and the traction wheel 3 is also in a winding state. When the car body runs on one side of the car to be saved, the car head of the car body is back to the car to be saved, then the supporting roller 2 is unreeled through the driving wheel, and in order to enable the escape net to be flatly unfolded, the car body is in a state of running in a direction far away from the car to be saved in the process of rotation of the driving wheel.

When a road running vehicle fails to run normally due to a fault or an accident, the fault vehicle is usually required to be pulled away from a traffic lane or returned to a repair shop by using an obstacle-removing vehicle in order to dredge the road or to repair the road in time. At present, the existing wrecker type lifting mechanism can only rescue small and light wheeled vehicles. If the fault vehicle is a heavy vehicle, because the front axle is loaded too heavy, when the obstacle-removing vehicle type lifting mechanism is used for carrying out supporting and traction, the overload of the rear axle and the tilting trend of the front axle of the rescue vehicle are easily caused, the adhesive force is insufficient, and the potential safety hazard exists in steering in the driving process.

When the vehicle falls into the silts or turns over on the road, the vehicle is first saved from the silts or turns over state by a crane, and then is towed away by a rescue vehicle. In order to facilitate the rescue, the used rescue vehicle is usually provided with a hanging and pulling device or a supporting and pulling device, wherein the hanging and pulling device is mainly characterized in that a crane is arranged in front of the vehicle, so that the crane can be used as a crane or used for hanging the front part of the rescue vehicle and then pulled away in a hard traction mode. The latter makes the trailing arm stretch to the lower part of waiting for the vehicle front axle of saving through setting up the trailing arm, then holds up the vehicle of being saved, blocks its front axle tire to pull away the vehicle, in the former, the latter has avoided hard traction to cause the vehicle of being saved to harm once more, has protected the vehicle of being saved more effectively.

In some embodiments of the large tonnage equipment dragging technology provided by the application, referring to fig. 1, a driving wheel for driving a supporting roller 2 to rotate is installed on a frame body 1. It should be noted that, after the support roller 2 unwinds the stranded wire, the head end of the stranded wire needs to be as close to the wheels of the vehicle to be saved as possible, and ideally, the head end directly contacts the wheels, because only in the above-mentioned case, the head end of the stranded wire can be moved to the bottom of the wheels by the rotation of the wheels of the vehicle to be saved without the need of the operation of getting off the vehicle by a worker.

The driving wheel in the application can unwind the supporting roller 2 at a certain speed, and more importantly, the driving wheel has a certain self-locking performance, because the waiting car can be dragged through the supporting roller 2 only in this way. The specific implementation mode is that the driving wheel is a worm wheel, the number of the worm wheels is two at the moment, the two worm wheels are fixed at the two ends of the supporting roller 2, worm wheels are connected with worm gears in a transmission mode, the worm gears are matched with the worm wheels, and a motor is connected with the worm gears in a transmission mode.

In some embodiments of the large tonnage equipment dragging technology provided by the present application, referring to fig. 1 and 2, an extension rope 4 is bolted between the support roller 2 and the escaping net, and the extension rope 4 is wound on the inner side of the escaping net.

When carrying out actual rescue, there is certain distance between automobile body and the car of waiting for rescue, and the automobile body needs to drag the car of waiting for rescue through a plurality of horizontal poles 6 and braided rope 10 simultaneously, because the interval between two cars is great, if all replace by horizontal pole 6 and braided rope 10, then be inconvenient for accomodate, and the cost is higher simultaneously. For this purpose, a connection is made between the braided rope 10 and the support roller 2 by means of an extension rope 4.

In some embodiments of the large tonnage equipment dragging technology provided by the present application, referring to fig. 2, 3 and 4, the escape net includes a plurality of crossbars 6 and a braiding rope 10 braiding the crossbars 6, and the length direction of the crossbars 6 is parallel to the axis direction of the wheels of the to-be-saved vehicle. In general, if the hardness of the road surface is low, the vehicle is trapped, and pits are formed in the ground due to the rotation of the wheels. The most traditional mode is to directly pull out the to-be-saved car through the car body, but at the moment, workers are required to get off the car, and bolting between the car body and the to-be-saved car is completed. However, when the environment in which the rescue vehicle is located is complex, even if the vehicle head is sunk into a mud pit or a water pit, the bolting of the traction hook is difficult to find.

In the application, two rescue modes exist, and when the wheels of the to-be-rescued vehicle are separated from the pits on the ground, the wheels can be completely rescued without supporting the wheels through the positioning ropes 5. The specific implementation mode is, the head end contact wheel after unreeling of the net that gets rid of poverty, and the wheel rotates just can have the effort of keeping away from the automobile body direction to the net that gets rid of poverty this moment, under the circumstances of this effort, just can make the bottom that gets into the wheel that gets rid of poverty, waits to rescue the car simultaneously and climbs along the net that gets rid of poverty to realize saving oneself.

The other situation is serious, that is, the wheels of the to-be-saved vehicle can rotate, but cannot climb by itself, and at the moment, the head end and the like are required to support the wheels. In order to allow the escape net to enter the bottom of the wheel under the condition of rotation of the wheel, and at the same time, to ensure that the escape net has certain structural strength and supporting capacity, the escape net is composed of a plurality of cross bars 6 and braiding ropes for ensuring the positions of the cross bars 6. The length of the cross bar 6 is parallel to the axis of the wheel, since only in this case the cross bar 6 will enter the bottom of the wheel under the effect of the wheel.

In some embodiments of the present application, referring to fig. 2, 3 and 4, a reinforcing sleeve 7 is sleeved on the head end, and the head end is rotatably disposed in the reinforcing sleeve 7. After the wheel bearing of waiting to rescue the car, need ensure that the head end is located the upside of wheel bottom all the time, because only just so can avoid the wheel to slip from getting rid of the net, and the key of guaranteeing the head end position is locating rope 5 and traction wheel 3, needs traction wheel 3 can have certain braking performance this moment, avoids the pine of locating rope 5 to take off.

More importantly, in the process of dragging the to-be-saved vehicle, the acting force of the wheels on the head end is different from the acting force of the positioning rope 5 on the head end, and if the structural strength of the head end is low, the head end can be bent or even broken.

For the above reasons, the reinforcing sleeve 7 is arranged at the head end, and the structural strength of the reinforcing sleeve 7 is larger than that of other cross bars 6, so that the stability of the structure can be ensured only. More importantly, the outer diameter of the reinforcing sleeve 7 is larger because if the outer diameter of the reinforcing sleeve 7 is smaller, the wheel may slip off the reinforcing sleeve 7 if not operated in time. When the outer diameter of the reinforcing sleeve 7 is larger, once the wheel passes over the reinforcing sleeve 7, the wheel can be effectively positioned, so that the effective bearing of the wheel is realized.

In some embodiments of the large tonnage equipment supporting and pulling technology provided by the application, referring to fig. 3, the outer sides of the two ends of the reinforcing sleeve 7 are provided with positioning rods 8, and a connecting part 9 is arranged between the positioning rods 8 and the reinforcing sleeve 7; the positioning rod 8 is parallel to the head end, and the positioning rope 5 is bolted between the positioning rod 8 and the traction wheel 3; the two positioning rods 8, the connecting part 9 and the reinforcing sleeve 7 form a U-shaped structure; the positioning rod 8 is used for moving into the pit at the wheel of the to-be-saved car.

Before the rescue of the car to be saved, the wheels rotate and form pits on the ground, if the reinforcing sleeve 7 is of a straight rod structure, the reinforcing sleeve 7 cannot enter the bottoms of the pits, and the wheels are difficult to pass over the reinforcing sleeve 7, because the reinforcing sleeve 7 is positioned on the upper side of the center line of the wheels under the condition, and the reinforcing sleeve 7 cannot support the wheels.

In view of the above, positioning rods 8 are provided at both ends of the reinforcing sleeve 7, and the distance between the two positioning rods 8 corresponds to the distance between the two wheels, that is, it is necessary to ensure that the two positioning rods 8 can contact the wheels at the same time. The positioning rod 8 is parallel to the reinforcing sleeve 7 and has a certain distance between the axes, because only then can the positioning rod 8 enter the pit with the reinforcing sleeve 7 located above the pit, so that the wheel can be supported when the wheel rotates.

In some embodiments of the large tonnage equipment supporting and pulling technology provided by the present application, referring to fig. 4, extension plates 11 are fixed at two ends of a reinforcing sleeve 7, the two extension plates 11 are in the same plane, a positioning rope 5 is bolted between the extension plates 11 and a traction wheel 3, and the extension plates 11 move upwards from the bottom of the wheel by means of the positioning rope 5 to support the wheel.

The main reason for the trapped rescue car is that the lower hardness of the ground makes the supporting force to the wheels lower, so that the wheels sink and cannot climb out of the formed pits. If an object capable of supporting the wheel and having a certain supporting force to the wheel exists in the pit at this time, self rescue can be realized easily through rotation of the wheel.

Based on the above-mentioned problem, need select reasonable rescue instrument according to the degree of sinking of wheel, if the degree of sinking of wheel is less, then can through selecting suitable locating lever 8, if the degree of sinking of wheel is great, just can install extension board 11 at the both ends of strengthening cover 7 this moment, extension board 11 has certain length, when extension board 11 gets into in the pit after, contact the wheel, along with the rotation of wheel, the wheel can support and lean on extension board 11 and thereby climb. And in the process of climbing the wheels, the extension plate 11 can quickly pass over the wheels through winding the positioning ropes 5 by the traction ropes, and the wheels are supported. It should be noted that this procedure requires the personnel on the truck to determine the time for winding the traction rope based on the relative position between the wheels and the extension plate 11.

In some embodiments of the large tonnage equipment dragging technique provided by the present application, referring to fig. 1, 2 and 3, the braided rope 10, the extension rope 4 and the positioning rope 5 are integrally formed. The purpose of the braided rope 10 is to provide a protective spacing between the plurality of crossbars 6 and to maintain a certain distance between two adjacent crossbars 6. When the wheels are between the two cross bars 6, the wheels can be well clamped and positioned through the cross bars 6, so that the rescue vehicle is prevented from retreating to a certain extent, and climbing and escaping of the rescue vehicle are easier.

Through the integrated into one piece setting, can improve the joint strength between braided rope 10, extension rope 4 and the locating rope 5, avoid because joint strength is lower and so on cause a series of problems such as fracture take place.

In some embodiments of the large tonnage equipment dragging technology provided by the present application, referring to fig. 2, 3 and 4, the number of positioning ropes 5 is two, and two positioning ropes 5 are distributed on two sides of the support roller 2. By providing the cross bar 6 and the positioning rope 5, the final purpose is to support the wheels of the vehicle body, so that the vehicle body can be supported and pulled. The number of the front wheels of the vehicle body is two, so that the front wheels can be effectively supported, the number of the positioning ropes 5 is two, and the head end can be pulled to move upwards under the action of the two positioning ropes 5.

In some embodiments of the present application, referring to fig. 2, 3 and 4, the length of the head end is greater than the length of the cross bar 6. If the positioning rope 5 is directly bolted to the head end, at this time, if the width of the head end is the same as that of the car body to be saved, the car body structure of the car to be saved is inevitably influenced, and in order to avoid such problems, the length of the head end is usually longer than that of the other cross bars 6, so that the influence on the car to be saved can be avoided.

The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
