Description

Technical Field

[0001] The utility model relates to a flatbed truck, in particular to a flatbed truck for hanging boxes on a monorail. Background Art

[0002] With the improvement of mechanized transportation level in coal mine production, surface flatbed truck transportation and underground monorail crane transportation have become two indispensable main transportation methods in the coal industry. Surface flatbed truck transportation is usually used to transport mined coal from the wellhead to ground processing facilities or directly load it onto transport vehicles, while underground monorail crane transportation is mainly used for transporting materials and personnel in underground tunnels.

[0003] Ordinary flatbed trucks do not have a structure specially designed to fix the monorail crane box. The monorail crane box is prone to displacement during transportation. Therefore, when transporting on a well flatbed truck, it is usually necessary to install a specific fixing device to fix the monorail crane box. However, after the installation, its use becomes single and it cannot flexibly adapt to the transportation needs of other types of goods. Utility Model Content

[0004] In order to overcome the shortcoming that a flatbed truck equipped with a fixing device is difficult to meet various transportation needs, the utility model provides a flatbed truck for a monorail hanging box.

[0005] The technical implementation scheme of the present utility model is: a flatbed truck for a monorail hanging box, comprising a bottom plate, a support frame, a top plate, wheels, a connecting mechanism, a lock seat and a dovetail lock, wherein wheels are installed on the lower side of the bottom plate, a support frame is provided on the upper side of the bottom plate, the top of the support frame carries the top plate, the bottom plate and the top plate are connected by a connecting mechanism, four lock seats are provided on the support frame, the top of the lock seat is lower than the top of the top plate, a dovetail lock is slidingly provided on the lock seat, the lock seat comprises a first limiting part and a second limiting part, the first limiting part is located on the left and right parts of the upper side of the lock seat body, and the opposite side thereof is designed to be inclined, the second limiting part is located on the left and right parts of the lock seat body away from the top plate, the dovetail lock comprises an embedded part, the embedded part is located on the left and right sides of the dovetail lock, and the outer edge of the embedded part is also designed to be inclined.

[0006] In addition, it is particularly preferred that the connecting mechanism includes a connecting rod, a pull ring and a pin, and through holes are opened at the left and right ends of the bottom plate and the top plate. The two connecting rods are slidingly connected to the through holes at the left and right ends of the bottom plate and the top plate respectively, and a pull ring is provided on the upper side of the connecting rod, and a pin is slidingly provided on the lower side of the connecting rod.

[0007] In addition, it is particularly preferred that the inclined portions of the first limiting portion and the embedded portion are adapted to each other, and when the dovetail lock is embedded in the lock seat, the inclined portions of the two are in close contact.

[0008] In addition, it is particularly preferred that the support frames are welded to the upper side of the base plate in a staggered manner.

[0009] In addition, it is particularly preferred that the lock seat is welded to the support frame according to the size of the monorail hanging box.

[0010] In addition, it is particularly preferred that the lock seat and the dovetail lock body are made of cast steel.

[0011] The beneficial effects of the present invention are as follows: 1.

DETAILED DESCRIPTION

[0019] The following will be combined with the accompanying drawings in 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 creative efforts are within the scope of protection of the present invention.

[0020] A flatbed car for a monorail hanging box, such as Figure 1-Figure 5 As shown, it includes a bottom plate 1, a support frame 2, a top plate 3, a wheel 4, a connecting mechanism 5, a lock seat 6 and a dovetail lock 7. The wheel 4 is installed on the lower side of the bottom plate 1, and a support frame 2 is provided on the upper side of the bottom plate 1. The top of the support frame 2 carries the top plate 3. The left and right ends of the bottom plate 1 and the top plate 3 are connected by two connecting mechanisms 5. Four lock seats 6 are provided on the support frame 2. The four lock seats 6 are respectively located near the top of the four corners of the bottom plate 1. The top of the lock seat 6 is lower than the top of the top plate 3. A dovetail lock 7 is slidably provided on the lock seat 6. The lock seat 6 includes a first limiting portion 61 and a second limiting portion 62. The first limiting portion The part 61 is located on the left and right parts of the upper side of the lock seat 6 main body, and its opposite side is designed to be inclined, and together with the lock seat 6 main body, it limits the up and down movement of the dovetail lock 7. The second limiting part 62 is located on the left and right parts of the lock seat 6 main body away from the top plate 3. The second limiting part 62 and the top plate 3 together limit the forward and backward movement of the dovetail lock 7. The dovetail lock 7 includes an embedded part 71, which is located on the left and right sides of the dovetail lock 7. The outer edge of the embedded part 71 also adopts an inclined design. The embedded part 71 is used together with the first limiting part 61 and the second limiting part 62 to fix the dovetail lock 7 on the lock seat 6.

[0021] When in use, the monorail hanging box is placed on the top plate 3 and locked with the dovetail locks 7 at the four corners of the utility model. Then the monorail hanging box can be transported by the utility model. After the transportation is completed, the dovetail locks 7 are released and the monorail hanging box is unloaded. When the dovetail locks 7 are no longer needed, the connecting mechanism 5 between the top plate 3 and the bottom plate 1 can be released, and the top plate 3 is separated from the bottom plate 1. At this time, the top plate 3 no longer restricts the movement of the dovetail locks 7, and the dovetail locks 7 can be slid out of the lock seat 6 toward the bottom plate 1. After the dovetail locks 7 are completely slid out, the top plate 3 is reinstalled. Since the top of the lock seat 6 is lower than the top of the top plate 3, when the dovetail locks 7 are removed, the upper surface of the utility model is flat, which does not affect the use of the utility model as an ordinary flatbed truck.

[0022] like Figure 2 and Figure 3As shown, the connecting mechanism 5 includes a connecting rod 51, a pull ring 52 and a latch 53. Through holes are opened at both ends of the bottom plate 1 and the top plate 3. The through holes at the left and right ends correspond to each other in the center. The two connecting rods 51 are slidably connected to the through holes at the left and right ends of the bottom plate 1 and the top plate 3 respectively. The upper part of the connecting rod 51 is slightly larger than the through hole. A pull ring 52 is provided on the upper side of the connecting rod 51. The pull ring 52 is located above the top plate 3. A latch 53 is slidably provided on the lower side of the connecting rod 51. The latch 53 is located below the bottom plate 1. The bottom plate 1 and the top plate 3 are connected by two connecting rods 51. The pull ring 52 on the upper side of the connecting rod 51 is located above the top plate 3 and can be used to lift or move the entire flatbed truck. The pin 53 is used to further fix the position of the connecting rod 51 to prevent it from shaking or falling off during transportation. When disassembling, slide the pin 53 out of the connecting rod 51, and then slide the connecting rod 51 out of the through holes of the bottom plate 1 and the top plate 3. After the connecting rods 51 on both sides are disassembled, the top plate 3 can be separated from the bottom plate 1.

[0023] The inclined parts of the first limiting part 61 and the embedding part 71 can adapt to each other. When the dovetail lock 7 is embedded in the lock seat 6, the inclined parts of the two parts can fit tightly; the inclined parts of the two are in close contact. This design can prevent the dovetail lock 7 from sliding on the lock seat 6, thereby ensuring that the monorail hanging box connected to the dovetail lock 7 does not deviate, ensuring safety and stability during transportation.

[0024] The support frames 2 are welded to the upper side of the base plate 1 in a staggered manner; by staggered welding of the support frames 2 to the upper side of the base plate 1, a more robust support structure can be formed, thereby improving the load-bearing capacity and anti-deformation ability of the flatbed truck.

[0025] The lock seat 6 is welded to the support frame 2 according to the size of the monorail hanging box; ensure that the positions of the lock seat 6 and the dovetail lock 7 can adapt to the monorail hanging box, thereby achieving a stable connection between the box and the flatbed truck to avoid shaking during transportation.

[0026] The main parts of the lock seat 6 and the dovetail lock 7 are both made of cast steel; cast steel has high strength and hardness, can resist deformation and wear, ensure that the lock seat 6 and the dovetail lock 7 have sufficient strength and durability, can withstand gravity and other external forces during transportation, thereby maintaining the stability and security of the connection.

[0027] It should be understood that the above description is only for illustrative purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be within the scope of the claims herein.
