Description

Technical Field

[0001] The present invention relates to the technical field of semi-trailers, and in particular to a laterally stable transport semi-trailer. Background Art

[0002] Transport semi-trailers include dump semi-trailers, which can use the engine to drive the hydraulic mechanism to drive the lifting mechanism to complete the tilting to achieve the purpose of unloading. It is a type of transport semi-trailer that is more convenient for unloading. Based on the lifting method, it can be divided into rear-tip type and side-tip type.

[0003] Among them, the rear-dump semi-trailer has a relatively high requirement for the height of the lifting jack. Usually, the height of the jack is affected by the length of the cargo compartment. The longer the cargo compartment is, the longer the jack is required. However, the design of the jack is a step-by-step design, and the thinner it is towards the top. Therefore, it is very unfavorable for the lateral stability of the lift. Relatively speaking, the biggest advantage of the side-dump semi-trailer is that it has a smaller requirement for the height of the lifting jack, even less than half the height of the rear-dump jack. The jack of the side-dump semi-trailer is generally evenly distributed in a straight line at the bottom of the cargo compartment, with a large lifting force and improved lateral stability. Especially for semi-trailers with longer cargo compartments, side-dumping is more suitable.

[0004] In the prior art, when a side-overturning dump truck unloads bulk materials such as coal, ore, and building materials, the materials tend to accumulate directly on the unloading side of the truck after flowing out of one side of the truck, burying the wheels and making it difficult for the truck to move out directly after unloading. At the same time, if the materials are large or piled high, the flow rate will be very fast when unloading from one side of the truck, and the downward pressure of the materials on the truck's loading side will easily cause lateral instability and rollover.

[0005] In the existing technology, the problem of being buried and obscured by materials can be basically solved by technology. That is, a shift rod is installed on the lower side of the rear of the car body. After unloading, the rear support position is continuously moved out by lifting and lowering the shift rod, so that the semi-trailer car body can be moved out of the material, solving the problem of the car body being buried by the material. However, the problem of the car body rolling over during side unloading mainly depends on the driver's experience, and rollover cannot be completely avoided. Therefore, we propose a transport semi-trailer that is laterally stable during side unloading. Summary of the Invention

[0006] The present invention provides a laterally stable transport semi-trailer, which solves the problem in the related art that a transport semi-trailer with a rollover self-unloading function is prone to being laterally unstable and rolling over when unloading.

[0007] The technical solutions of the present invention are as follows:

[0008] A laterally stable transport semi-trailer comprises a vehicle body, a carriage mounted on the vehicle body, a discharge port formed on the carriage, and a blocking door mounted at the discharge port, and further comprises:

[0009] Two diversion and unloading support mechanisms, the two diversion and unloading support mechanisms are respectively installed on both sides of the carriage in the transverse direction, and are used to guide the unloaded materials when the two blocking doors are unloading, and are also used to provide transverse support for the carriage;

[0010] Wherein, a single diversion and unloading support mechanism includes:

[0011] A guide stripper plate is hingedly connected to a lower portion of one side in the longitudinal direction of the carriage, and a fixing mechanism is provided between the guide stripper plate and the carriage, the fixing mechanism being used to limit the guide stripper plate to a state of being parallel to and attached to one side of the carriage;

[0012] A turning plate, which is hinged on the side of the guide unloading plate facing the carriage, and is used to turn the material on the turning plate down after unloading;

[0013] A triangular support frame, wherein the triangular support frame is provided in plurality, and the plurality of triangular support frames are hinged to a side of the guide unloading plate away from the carriage;

[0014] A linkage pull rod is hinged at the same time on one side of the multiple triangular support frames away from the guide unloading plate, and a limiting mechanism 1 and a limiting mechanism 2 are arranged between the linkage pull rod and the multiple triangular support frames. The limiting mechanism 1 is used to limit the positions of the multiple triangular support frames when the multiple triangular support frames are parallel to the guide unloading plate, and the limiting mechanism 2 is used to limit the positions of the multiple triangular support frames when the multiple triangular support frames are perpendicular to the guide unloading plate.

[0015] In a preferred embodiment, the fixing mechanism includes:

[0016] a socket, the socket being fixedly connected to the guide and discharge plate;

[0017] A limit seat, the limit seat being fixedly connected to the carriage;

[0018] A limiting pin is used to connect the socket and the limiting seat.

[0019] In a preferred embodiment, the first limiting mechanism includes:

[0020] Limit bolt 1;

[0021] A through hole 1, the through hole 1 being provided on the linkage pull rod and being used for the limiting bolt 1 to pass through;

[0022] Thread groove 1, the thread groove 1 is provided on the triangular support frame and is used for threading the limiting bolt 1 onto the triangular support frame.

[0023] In a preferred embodiment, the second limiting mechanism includes:

[0024] Limit bolt 2;

[0025] A second through hole is provided on the linkage pull rod and is used for the second limiting bolt to pass through;

[0026] A second thread groove is provided on the triangular support frame and is used for threadably connecting the second limiting bolt to the triangular support frame.

[0027] In order to avoid the loss of the limiting bolt 1 and the limiting bolt 2, further, a connecting rope is connected between the limiting bolt 1 and the limiting bolt 2 and the linkage pull rod.

[0028] In order to increase the support points of the triangular support frame, a plurality of supporting legs are further fixedly connected to the triangular support frame.

[0029] In order to facilitate the manipulation of the flipping plate for flipping, a handle is further fixedly installed on the flipping plate.

[0030] In order to facilitate the installation and removal of the diversion and unloading support mechanism, the diversion and unloading support mechanism also includes a mounting seat, the mounting seat is detachably connected to the carriage, and the diversion and unloading plate is hinged on the mounting seat.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. In the present invention, during side unloading, the multiple triangular support frames can be pulled together to be perpendicular to the guide unloading plate through the linkage pull rod, and then the two guide unloading plates can be flipped down. Under the support of the multiple triangular support frames, the two guide unloading plates can be supported on the ground in a slope shape and supported on both sides of the vehicle body, thereby increasing the lateral stability of the vehicle body;

[0033] 2. In the present invention, during unloading, if the carriage is of a double-sided unloading type, the two guide unloading plates can be used to guide and unload materials evenly on both sides, thereby improving lateral stability. If the carriage is of a single-sided unloading type, one guide unloading plate is used for unloading, and the guide unloading plate on the other side and the multiple triangular support frames can be increased with counterweights or fixed with tools such as ropes, thereby actively increasing the stability of the side opposite to the unloading side of the carriage, thereby increasing the overall lateral stability of the carriage body.

[0034] 3. In the present invention, during unloading, on the one hand, the material can be diverted and discharged through the slope of the diversion discharge plate, which has better cushioning performance compared with the prior art method of directly unloading from the height of the discharge port to the ground. At the same time, because the material is directly diverted by the slope on the diversion discharge plate to a position farther away from the wheels of the vehicle body, the material is not likely to bury the wheels during unloading, and the vehicle body can be driven away more easily and conveniently after unloading;

[0035] 4. In the present invention, since the guide unloading plate is also hinged with a flipping plate, when the slope is used for diversion and unloading, the guide unloading plate and the flipping plate are equivalent to a double-layer inclined plate, which has higher support and pressure bearing capacity. At the same time, if a small amount of material does not completely slide off the flipping plate after unloading, the material can be quickly and conveniently flipped off by flipping one flipping plate;

[0036] 5. Therefore, the present invention improves the lateral stability of the vehicle body by installing two diversion and unloading support mechanisms on both sides of the vehicle body, making it less likely to roll over during unloading. At the same time, the unloaded materials can be diverted during unloading. The stability of the materials during unloading can also reduce the probability of the vehicle body rolling over due to lateral instability caused by the sudden downward pressure of the materials on one side of the vehicle body.

[0054] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0055] like Figures 1 to 11 As shown, the present invention proposes a laterally stable transport semi-trailer, comprising a body 1, a compartment 2 mounted on the body 1, a discharge port opened on the compartment 2, and a blocking door 3 mounted at the discharge port, and further comprising:

[0056] Two diversion and unloading support mechanisms 4 are respectively installed on both sides of the carriage 2 in the horizontal direction, and are used to guide the unloaded materials when the two blocking doors 3 are unloading, and are also used to provide lateral support for the carriage 2;

[0057] Among them, a single diversion and unloading support mechanism 4 includes a diversion and unloading plate 101, a flipping plate 102, a triangular support frame 103 and a linkage rod 104. The diversion and unloading plate 101 is hinged at the lower part of one side in the length direction of the car body 2. The height of the diversion and unloading plate 101 should be sufficient to be tilted and supported on the ground when the diversion and unloading plate 101 is flipped down. In order to facilitate the installation and disassembly of the diversion and unloading support mechanism 4, the diversion and unloading support mechanism 4 also includes a mounting seat 107. The mounting seat 107 is detachably connected to the car body 2, for example, by a plurality of bolts. The diversion and unloading plate 101 is hinged on the mounting seat 107. Through the installation of the mounting seat 107, the diversion and unloading support mechanism 4 in the present application can be freely installed on different types of side-rolling dump transport semi-trailers;

[0058] like Figure 1 and Figure 2 As shown, since the deflector unloading plate 101 can be flipped to fit on one side of the car body 2 when there is no need to unload, the space occupied on both sides of the car body 1 is reduced, and at the same time, both sides of the car body 1 can be further blocked. For example, it can be blocked on the outside of the baffle 3 to prevent the baffle 3 from leaking when it is damaged. The railing-shaped baffle 3 also has a certain effect of preventing materials from falling from the gap. However, since the deflector unloading plate 101 is hinged to the lower part of one side in the length direction of the car body 2, if it is accidentally flipped over, the flipping force from top to bottom will pose a certain safety hazard. Therefore, it is necessary to limit the state of the deflector unloading plate 101 being parallel to and fitting on one side of the car body 2. Therefore, a fixing mechanism is required between the deflector unloading plate and the car body 2. At the same time, in order to ensure the stability of the fixation, the fixing mechanism is also provided in multiple forms, preferably First, set it to two, which are located on both sides of the diversion unloading plate 101 respectively. In a preferred manner, the fixing mechanism includes a socket 201, a limit seat 202 and a limit pin 203. The socket 201 is fixedly connected to the diversion unloading plate 101, and the limit seat 202 is fixedly connected to the carriage 2. Through holes are provided on the socket 201 and the limit seat 202, and the socket 201 and the limit seat 202 are connected by the limit pin 203. When the diversion unloading plate 101 is parallel to one side of the carriage 2, the through holes on the socket 201 and the limit seat 202 correspond, and the limit pin 203 is inserted into the through holes on the socket 201 and the limit seat 202 at the same time, so that the fitting state of the diversion unloading plate 101 can be limited and fixed. The fixing function of the fixing pin is more flexible and convenient, and other structures such as locks can also be used for limiting and fixing.

[0059] like Figure 7As shown, the flipping plate 102 is hinged on the side of the guide unloading plate 101 facing the carriage 2, and is used to flip the material on the flipping plate 102 after unloading. In order to facilitate the manipulation of the flipping plate 102 for flipping, a handle 106 is further fixedly installed on the flipping plate 102. During the slope diversion unloading, it is equivalent to the guide unloading plate 101 and the flipping plate 102 being a double-layer inclined plate, with the flipping plate 102 on top, and the side away from the guide unloading plate 101 is used for backflow unloading, which has higher support and pressure bearing capacity. At the same time, if a small amount of material does not completely slide off the flipping plate 102 after unloading, the flipping plate 102 can be flipped by the handle 106, so that all the materials can be quickly and conveniently flipped off.

[0060] There are multiple triangular support frames 103, and the multiple triangular support frames 103 are all hinged on the side of the deflector unloading plate 101 away from the car body 2. In order to increase the support of the triangular support frame 103 at multiple points, further, multiple supporting legs 105 are fixedly connected to the triangular support frame 103, and the linkage pull rod 104 is simultaneously hinged on the side of the multiple triangular support frames 103 away from the deflector unloading plate 101, and a limiting mechanism 1 and a limiting mechanism 2 are set between the linkage pull rod 104 and the multiple triangular support frames 103. For the stability of the fixation, the limiting mechanism 1 and the limiting mechanism 2 can be set in multiples. The limiting mechanism 1 is used to limit the positions of the multiple triangular support frames 103 when the multiple triangular support frames 103 are parallel to the deflector unloading plate 101, and the limiting mechanism 2 is used to limit the positions of the multiple triangular support frames 103 when the multiple triangular support frames 103 are perpendicular to the deflector unloading plate 101;

[0061] In a preferred embodiment, the limiting mechanism 1 includes a limiting bolt 1 301, a through hole 1 and a thread groove 1, the through hole 1 is provided on the linkage pull rod 104 for the limiting bolt 1 301 to pass through, the thread groove 1 is provided on the triangular support frame 103, and is used to thread the limiting bolt 1 301 onto the triangular support frame 103103; the limiting mechanism 2 includes a limiting bolt 2 302, a through hole 2 and a thread groove 2, the through hole 2 is provided on the linkage pull rod 104 for the limiting bolt 2 302 to pass through, the thread groove 2 is provided on the triangular support frame 103, and is used to thread the limiting bolt 2 302 onto the triangular support frame 103103. At the same time, in order to avoid the loss of the limiting bolt 1 301 and the limiting bolt 2 302, further, a connecting rope 303 is connected between the limiting bolt 1 301 and the limiting bolt 2 302 and the linkage pull rod 104;

[0062] The linkage pull rod 104 can quickly pull the multiple triangular support frames 103 at the same time to achieve the transition between the multiple triangular support frames 103 and the guide unloading plate 101 in parallel and the multiple triangular support frames 103 and the guide unloading plate 101 in vertical support. Figure 1 and Figure 2As shown, when the multiple triangular support frames 103 are parallel to the guide and discharge plate 101, the limiting bolt 101 passes through the through hole 1 on the linkage rod 104 and is threaded into the thread groove 1, so that the linkage rod 104 can be fixed on the triangular support frame 103, so that the linkage rod 104 cannot pull and flip the triangular support frame 103, thereby fixing the current state of the triangular support frame 103;

[0063] like Figure 3 and Figure 4 As shown, when multiple triangular support frames 103 are perpendicular to the guide discharge plate 101, the limiting bolt 2 302 passes through the through hole 2 on the linkage rod 104 and is threadedly connected in the thread groove 2, so that the linkage rod 104 can be limited and fixed on the other side of the triangular support frame 103, so that the triangular support frame 103 can no longer be flipped, thereby fixing the current state of the triangular support frame 103.

[0064] The working principle of this laterally stable transport semi-trailer is:

[0065] When unloading, you can first unscrew the multiple limit bolts 301 so that the linkage rod 104 can pull the multiple triangular support frames 103. The linkage rod 104, the guide unloading plate 101 and the multiple triangular support frames 103 are similar to multiple parallelograms, until the multiple triangular support frames 103 are pulled perpendicular to the guide unloading plate 101, and the width surface of the triangular support frame 103 will be parallel to the guide unloading plate 101. If the semi-trailer is a double-sided unloading type, the two guide unloading plates 101 can be unfastened through the fixing mechanism to release the adhesion state of the two guide unloading plates 101 on the car body 2, and the two guide unloading plates 101 can be flipped in the direction away from the car body 1 until the multiple triangular support frames 103 are supported on the ground. The multiple triangular support frames 103 also support the guide unloading plate 101 into an inclined shape, such as Figure 8 As shown, the doors 3 on both sides of the carriage 2 can be opened at this time, and the material can be discharged evenly on both sides of the carriage 2, with better lateral stability.

[0066] If the car body 2 is of the one-side unloading type, since the material will flow out quickly from one side of the car body 1, there will be a short-term strong downward pressure on this side. Due to the downward pressure on this side, the other side of the car body 1 may flip up due to its relatively light weight, and the lateral stability between the two sides will be greatly unbalanced, resulting in rollover. At this time, a fixing mechanism at a guide unloading plate 101 can be used to release the contact state of a guide unloading plate 101 on the car body 2, and it can be flipped over and supported on the ground. The guide unloading plate 101 is used for unloading. If the guide unloading plate 101 on the other side is kept in contact with the side of the car body 2, but the multiple triangular support frames 103 are in a vertical state with the guide unloading plate 101, counterweights can be directly placed in the multiple triangular support frames 103 on the side where no unloading is done, such as cylindrical counterweights, such as Figure 9As shown, the stability of the counterweight on the non-unloading side of the vehicle body 1 can be increased, and tools such as ropes can be used to pass through multiple triangular support frames 103 and fixed on stones, buildings, trees, etc. in the surrounding environment, such as Figure 10 As shown, actively stabilize that side;

[0067] Even if it is a single-side unloading type, the two guide unloading plates 101 can be turned down at the same time, and a counterweight can be placed above the guide unloading plate 101 on the non-unloading side, such as Figure 11 As shown, since the guide unloading plate 101 is in a lower position after being turned over, the center of gravity of the counterweight is lower after the counterweight is placed, which also has a good stabilizing effect on the side of the vehicle body 1 where the material is not unloaded;

[0068] When the non-unloading side of the vehicle body 1 is well stabilized, even if the gravity of the material increases on the unloading side of the vehicle body 1, the vehicle body 1 can have a more balanced stabilization effect in the lateral direction, and is less likely to roll over during side unloading, thus having higher safety.

[0069] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
