Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to an anti-slip auxiliary device for slope transportation and a rubber-tyred vehicle using the same. Background Art

[0002] In the auxiliary transportation in coal mines in China, rubber-tyred vehicles without rails are used more and more. Due to the lack of track restrictions, this kind of vehicle has the characteristics of being flexible, adaptable, safe, efficient, and having a wide application range. It is getting more and more attention and is an advanced auxiliary transportation vehicle for transporting materials, equipment, and personnel. When the rubber-tyred vehicle is transporting heavy loads continuously uphill, it is easy to cause the vehicle to slide down or the heavy load to slide down, increasing the safety risk. At present, the safety of transportation is mainly improved by reducing the vehicle speed and increasing the road transportation platform, but there is no road transportation platform in some transportation scenarios where the rubber-tyred vehicle transports heavy loads continuously uphill.

[0003] Therefore, on the basis of preventing the vehicle from sliding down or the heavy load from sliding down during the uphill transportation of heavy loads and increasing the safety risk, the purpose of the research of the present utility model is to design an anti-slip auxiliary device for slope transportation and a rubber-tyred vehicle using the same, which can apply resistance to resist the sliding force of the rubber-tyred vehicle and the load during the sliding process of the heavy load of the rubber-tyred vehicle, and give a resistance force to resist the front of the vehicle from tilting caused by the sliding of the load, maximize the safety of continuous uphill transportation, serve the short-distance uphill transportation of heavy loads of rubber-tyred vehicles, effectively avoid dangerous accidents caused by continuous uphill transportation of heavy loads, and improve the safety. Content of the Utility Model

[0004] In view of the above technical problems existing in the prior art, the present utility model provides an anti-slip auxiliary device for slope transportation and a rubber-tyred vehicle using the same, which can effectively solve the technical problems existing in the above prior art.

[0005] The technical solution of the present utility model is as follows:

[0006] An anti-slip auxiliary device for slope transportation, characterized by comprising:

[0007] A support and blocking member, fixedly installed at the tail of the rubber-tyred vehicle carriage;

[0008] A plurality of positioning components, fixedly connected to the outside of the support and blocking member at horizontal intervals, and the positioning components connect the support and blocking member and the bottom of the rubber-tyred vehicle carriage;

[0009] A resistance member, which is arranged corresponding to the positioning component one by one, and the resistance member is rotatably connected to the positioning component; when the rubber-tyred vehicle is loaded with heavy loads, the resistance member is turned outwards until the end part not connected to the positioning component is spaced from the ground; when the rubber-tyred vehicle is empty, the resistance member is turned inwards until it abuts against the upper part of the support and blocking member;

[0010] A telescopic adjustment mechanism is connected to the resistance member and the positioning assembly and is used to adjust the distance between the resistance member and the ground. When the rubber-tired vehicle is going uphill with a heavy load, the telescopic adjustment mechanism acts to push the resistance member outwards, and the resistance member is pushed by the connection assembly and extends out and inserts into the ground.

[0011] The telescopic adjustment mechanism includes a hollow connection member rotatably connected to the positioning assembly. One end of the hollow connection member connected to the positioning assembly is closed, and the other end is open and can telescopically and movably insert the resistance member. A corresponding connection assembly is installed between the resistance member and the top wall of the hollow connection member. The connection assembly includes a connection base and a connection rod that are hinged to each other. The connection base and the connection rod are respectively hinged to the corresponding resistance member and the hollow connection member. One side where the connection base and the connection rod are bent is respectively connected to the inner side wall of the hollow connection member through corresponding elastic members, and an electromagnet is provided on the other side of the hollow connection member where no elastic member is provided. When the rubber-tired vehicle is going uphill with a heavy load, after the electromagnet is energized, the connection base and the connection rod rotate towards the electromagnet side under the magnetic force until the connection base and the connection rod are in a straight line, the elastic members are stretched, and the resistance member is pushed outwards by the connection assembly and extends out and inserts into the ground.

[0012] The electromagnet is electrically connected to the power system of the front of the rubber-tired vehicle.

[0013] Both the connection base and the connection rod are made of magnetic steel or iron materials.

[0014] The support and blocking member is a vertical I-beam fixedly installed at the tail of the carriage of the rubber-tired vehicle by full welding.

[0015] The positioning assembly includes two positioning steel plates arranged horizontally at intervals. Installation through holes are correspondingly provided at the upper ends of one sides of the positioning steel plates that are not connected to the support and blocking member and the bottom of the carriage of the rubber-tired vehicle. Through the connection of the installation through holes, the hollow connection member is hingedly installed on the positioning steel plates.

[0016] The positioning steel plates are made of steel plates with a thickness of at least 10 mm, and the vertical I-beam is full-welded to the bottom of the carriage of the rubber-tired vehicle through the positioning steel plates.

[0017] A rubber-tired vehicle with a slope transportation anti-slip auxiliary device includes a rubber-tired vehicle body, and the slope transportation anti-slip auxiliary device is installed at the tail of the carriage of the rubber-tired vehicle body.

[0018] Advantages of the present utility model:

[0019] 1) The utility model can effectively resist the downward sliding force of the rubber-tyred vehicle and the load by applying resistance when the rubber-tyred vehicle is transporting heavy loads uphill, and give a resistance to resist the upward tilting of the vehicle head caused by the downward sliding of the load, maximizing the safety of continuous uphill transportation, serving the short-distance heavy-load uphill transportation of rubber-tyred vehicles, effectively avoiding dangerous accidents caused by continuous uphill transportation of heavy loads, and improving safety.

[0020] 2) The utility model adjusts the rotation position of the resistance member arranged by hinge to meet the resistance requirements when the rubber-tyred vehicle is transporting heavy loads uphill and when it is empty. When the vehicle is empty, the resistance member is turned inward and retracted to help the rubber-tyred vehicle run smoothly; when the rubber-tyred vehicle is transporting heavy loads uphill, the resistance member is turned outward so that the resistance member is inserted into the ground to form a resistance to resist the downward sliding force.

[0021] However, since the rubber-tyred vehicle has the situation of running on flat ground with no load and with heavy load, the empty carriage is likely to block the retraction of the resistance member, and when running on flat ground with heavy load, the resistance member inserted into the ground will also hinder the running of the rubber-tyred vehicle. Therefore, by installing a telescopic adjustment mechanism between the resistance member and the positioning component, when running on flat ground with heavy load or when the vehicle is empty, the resistance member retracts into the telescopic adjustment mechanism to ensure the setting of the distance between the resistance member and the ground; when transporting heavy loads uphill, the telescopic adjustment mechanism acts to push the resistance member out and insert it into the ground to achieve the protection effect.

[0022] 3) The utility model drives the articulated connection base and the connecting rod to swing and straighten to be in the same straight line by electrifying the electromagnet, and then pushes the resistance member to extend outward. By cutting off the power supply of the electromagnet, under the elastic reset action of the elastic member, the connection base and the connecting rod swing to form a V shape, thereby pulling the resistance member back into the hollow connecting member. The structure is simple and easy to implement, and it can be directly connected to the power system of the rubber-tyred vehicle to achieve it.

[0023] When the rubber-tyred vehicle is empty or running on flat ground with heavy load, the electromagnet is powered off. Under the elastic reset action of the elastic member, the connection base and the connecting rod both rotate towards the elastic member side and drive the resistance member to retract deeply into the hollow connecting member, effectively avoiding the resistance member from affecting the running of the rubber-tyred vehicle and improving its practical effect.

[0031] For the convenience of those skilled in the art to understand, the structure of the present utility model will be further described in detail below in conjunction with the attached drawings:

[0032] Embodiment 1

[0033] Referring to Figures 1-6 , an anti-slip auxiliary device for slope transportation, comprising:

[0034] A support stopper 1, fixedly installed at the tail of the rubber-tyred vehicle carriage;

[0035] A plurality of positioning assemblies 2, fixedly connected to the outside of the support stopper 1 at horizontal intervals, and the positioning assemblies 2 connect the support stopper 1 and the bottom of the rubber-tyred vehicle carriage;

[0036] A resistance member 3, the resistance member 3 is arranged corresponding to the positioning assembly 2 one by one, and the resistance member 3 is rotatably connected to the positioning assembly 2; when the rubber-tyred vehicle is fully loaded, the resistance member 3 is turned outwards until the end part not connected to the positioning assembly 2 is spaced from the ground; when the rubber-tyred vehicle is empty, the resistance member 3 is turned inwards until it abuts above the support stopper 1;

[0037] A telescopic adjustment mechanism, connecting the resistance member 3 and the positioning assembly 2 and used for adjusting the distance between the resistance member 3 and the ground. When the rubber-tyred vehicle is going uphill fully loaded, the telescopic adjustment mechanism acts to push the resistance member 3 outwards and is pushed by the connecting assembly to insert into the ground.

[0038] The present utility model adjusts the rotation position of the resistance member 3 arranged by hinge to meet the resistance requirements when the rubber-tyred vehicle is going uphill fully loaded and empty. When the vehicle is empty, the resistance member 3 is turned inwards and retracted to help the rubber-tyred vehicle run smoothly; when the rubber-tyred vehicle is going uphill fully loaded, the resistance member 3 is turned outwards so that the resistance member 3 inserts into the ground to form a resistance to resist the downward sliding force;

[0039] However, since the rubber-tired vehicle has the situations of running on flat ground with no load and full load, the empty carriage is likely to block the retraction of the resistance member 3, while when the resistance member 3 is inserted into the ground during running on flat ground with full load, it will hinder the running of the rubber-tired vehicle. Therefore, by installing a telescopic adjustment mechanism between the resistance member 3 and the positioning assembly, when running on flat ground with full load or no load, the resistance member 3 retracts into the telescopic adjustment mechanism to ensure the setting of the distance between the resistance member 3 and the ground; when running uphill with full load, the telescopic adjustment mechanism acts to push the resistance member 3 out and insert it into the ground to achieve the protection effect.

[0040] The telescopic adjustment mechanism includes a hollow connecting member 4 rotatably connected to the positioning assembly 2. One end of the hollow connecting member 4 connected to the positioning assembly 2 is closed, and the other end is open and can telescopically and movably insert the resistance member 3; a corresponding connecting assembly is installed between the top wall of the resistance member 3 and the hollow connecting member 4. The connecting assembly includes a connecting base 5 and a connecting rod 6 which are hinged to each other. The connecting base 5 and the connecting rod 6 are respectively hinged to the corresponding resistance member 3 and the hollow connecting member 4; one side where the connecting base 5 and the connecting rod 6 are bent is respectively connected to the inner side wall of the hollow connecting member 4 through corresponding elastic members 8, and an electromagnet 7 is provided on the other side of the hollow connecting member 4 where no elastic member 8 is provided; when the rubber-tired vehicle runs uphill with full load, after the electromagnet 7 is powered on, the connecting base 5 and the connecting rod 6 rotate to the side of the electromagnet 7 under the action of magnetic force until the connecting base 5 and the connecting rod 6 are in the same straight line, the elastic member 8 is stretched, and the resistance member 3 is pushed outwards by the connecting assembly and inserted into the ground.

[0041] The electromagnet 7 is electrically connected to the power system of the head of the rubber-tired vehicle.

[0042] Both the connecting base 5 and the connecting rod 6 are made of magnetic steel or iron materials.

[0043] In the utility model, when the electromagnet 7 is powered on, the hinged connecting base 5 and connecting rod 6 swing and straighten to be in the same straight line, and then push the resistance member 3 to extend outwards. When the electromagnet 7 is powered off, under the elastic reset action of the elastic member 8, the connecting base 5 and the connecting rod 6 swing to form a V shape, thereby pulling the resistance member 3 back into the hollow connecting member. The structure is simple and easy to implement, and it can be directly connected to the power system of the rubber-tired vehicle to achieve.

[0044] The support and blocking member 1 is a vertical I-beam fixedly installed at the tail of the carriage of the rubber-tired vehicle by full welding.

[0045] The positioning assembly 2 includes two positioning steel plates arranged at a horizontal interval. Installation through holes are correspondingly arranged at the upper ends of the sides of the positioning steel plates that are not connected to the support and blocking member 1 and the bottom of the carriage of the rubber-tired vehicle. Through the connection of the installation through holes, the hollow connecting member 4 is hingedly installed on the positioning steel plates.

[0046] The positioning steel plate is made of a steel plate with a thickness of at least 10 mm, and the vertical I-beam is fully welded to the bottom of the rubber-tyred vehicle carriage through the positioning steel plate.

[0047] During the downhill sliding of the rubber-tyred vehicle, the resistance member 3 rotates downward by an angle a until the resistance member 3 is inserted into the floor. As the angle a increases, F3 and F4 increase. When the vehicle reaches stability, the final forces are as follows: F1 = F3, F2 = F4, where F1 is the downhill sliding force of the rubber-tyred vehicle, F2 is the force that causes the front of the vehicle to tilt up due to the downhill sliding of the load, F3 is the resistance force that prevents the rubber-tyred vehicle from sliding downhill when the I-beam is inserted into the floor, and F4 is the resistance force that prevents the front of the vehicle from tilting up due to the downhill sliding of the load when the I-beam is inserted into the floor. When the forces reach equilibrium, the downhill sliding of the rubber-tyred vehicle can be effectively prevented.

[0048] The utility model can effectively resist the downhill sliding forces of the rubber-tyred vehicle and the load by applying resistance during the uphill transportation of the heavily loaded rubber-tyred vehicle, and give a resistance force to resist the tilting of the front of the vehicle caused by the downhill sliding of the load, maximizing the safety of continuous uphill transportation, serving the uphill transportation of the short-distance heavily loaded rubber-tyred vehicle, effectively avoiding dangerous accidents caused by continuous uphill transportation of the load, and improving safety.

[0049] When the rubber-tyred vehicle is empty or running on a flat ground with a heavy load, the electromagnet 7 is powered off. Under the elastic reset action of the elastic member 8, the connecting base 5 and the connecting rod 6 both rotate towards the elastic member 8 and drive the resistance member 3 to retract and penetrate into the hollow connecting member 4, effectively avoiding the influence of the resistance member 3 on the operation of the rubber-tyred vehicle and improving its practical effect.

[0052] The above are only the preferred embodiments of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model.
