Description

Technical Field

[0001] This application relates to the field of dual-trailer transport vehicle technology, and more particularly to a dual-trailer tanker transport vehicle. Background Technology

[0002] Tank trucks are vehicles equipped with tank-like containers used to transport liquids, gases, or powdery substances. Since the tanks of tank trucks are usually sealed containers, the materials inside are not affected by weather conditions. If the materials have temperature requirements, they can also be made into tanks with special structures such as insulated tanks or heated tanks to protect the materials and ensure that the materials do not deteriorate, become contaminated, or leak. Therefore, they are widely used in the transportation of chemical products.

[0003] While existing dual-trailer tank trucks can transport two sets of tanks relatively well, the tanks are not well secured on the chassis when placed on the chassis. This reduces the effectiveness of securing tanks of different sizes on the chassis when transporting tanks of different sizes, thus reducing the overall flexibility of dual-trailer trucks. Utility Model Content

[0004] This application provides a dual-trailer tanker transport vehicle to solve the problem that the clamping and fixing effect of transport tanks on the vehicle frame is not high, which reduces the clamping and fixing effect of transport tanks of different sizes on the vehicle frame when transporting and using them.

[0005] This application provides a dual-trailer tank transport vehicle, including a tractor frame, one end of which is detachably connected to a connecting frame. A placement block is fixedly connected to the outer wall of the tractor frame, and a tank is placed on the outer wall of the placement block. A servo motor is provided on the outer wall of the tractor frame, and a threaded rod is fixedly connected to the output end of the servo motor. A threaded slide rod is threadedly connected to the outer wall of the threaded rod and slidably connected to the outer wall of the tractor frame. A clamping block located on one side of the tank is fixedly connected to the outer wall of the threaded slide rod.

[0006] Preferably, a fixing groove is provided at the connection between the outer wall of the tractor frame and the threaded slide rod.

[0007] Preferably, the threaded rod is provided in two sets, and the two sets of threaded rods rotate in opposite directions.

[0008] Preferably, there are two sets of clamping blocks, and the positions of the two sets of clamping blocks are symmetrical about the central axis of the threaded slide bar, and the threaded slide bar and the threaded rod are arranged in a one-to-one correspondence.

[0009] Preferably, a connecting plate is fixedly connected to the outer wall of the connecting frame, a connecting rod is fixedly connected to the outer wall of the traction frame and inserted into the outer wall of the connecting plate, an insert rod is inserted into the outer wall of the connecting plate and inserted into the outer wall of the connecting rod, a first insertion hole is provided at the connection part between the outer wall of the connecting plate and the insert rod, and a second insertion hole is provided at the connection part between the outer wall of the connecting rod and the insert rod.

[0010] The connecting plate is provided in two sets, and the spacing between the two sets of connecting plates is adapted to the thickness of the connecting rod. Both the connecting rod and the connecting plate are provided in two sets, and the two sets of connecting rod and connecting plate are staggered with each other.

[0011] Preferably, the outer wall of the connecting rod is provided with an electric push rod, one end of the electric push rod is fixedly connected to a sliding rod, the outer wall of the sliding rod is fixedly connected to a locking rod that engages with the outer wall of the insert rod, and a locking groove is provided at the connection between the outer wall of the insert rod and the locking rod.

[0012] Preferably, there are two sets of locking rods, and the positions of the two sets of locking rods are symmetrical about the central axis of the sliding rod, and the insertion rod and the locking rod are arranged in a one-to-one correspondence. Beneficial effects

[0013] While existing dual-trailer tanker trucks can transport two sets of tanks relatively well, the clamping and securing effect of the tanks on the chassis is not high when the tanks are placed on the chassis. This reduces the overall flexibility of the dual-trailer truck when transporting tanks of different sizes.

[0014] When different sizes of transport tanks need to be placed on a double trailer for use, in order to improve the flexibility of clamping and fixing transport tanks of different sizes on the frame, the servo motor is turned on and the threaded rod rotates, which drives the threaded slide rod to slide along the inner wall of the fixing groove, and drives the clamping block to slide synchronously. This allows the clamping block to center and clamp the transport tank around its perimeter, thereby improving the ease of installation and use of transport tanks of different sizes on the frame.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figure 1-5The illustrated dual-trailer tanker transport vehicle includes a tractor frame 1, a connecting frame 2 detachably connected to one end of the tractor frame 1, a placement block 3 fixedly connected to the outer wall of the tractor frame 1, a tank 4 placed on the outer wall of the placement block 3, a servo motor 5 provided on the outer wall of the tractor frame 1, a threaded rod 6 fixedly connected to the output end of the servo motor 5, a threaded slide rod 7 threadedly connected to the outer wall of the threaded rod 6 and slidably connected to the outer wall of the tractor frame 1, and a clamping block 9 located on one side of the tank 4 fixedly connected to the outer wall of the threaded slide rod 7.

[0031] Among them, a fixing groove 8 is provided at the connection between the outer wall of the tractor frame 1 and the threaded slide bar 7.

[0032] The setting of the fixed groove 8 is conducive to achieving the effect of limiting the sliding of the threaded slide rod 7.

[0033] The threaded rod 6 is provided in two sets, and the two sets of threaded rod 6 rotate in opposite directions.

[0034] This allows for the relative sliding of the threaded slide bar 7 by setting two sets of threaded rods 6 with opposite rotation directions.

[0035] The clamping blocks 9 are provided in two sets. The positions of the two sets of clamping blocks 9 are symmetrical about the central axis of the threaded slide bar 7. The threaded slide bar 7 and the threaded rod 6 are arranged in a one-to-one correspondence.

[0036] By setting two sets of clamping blocks 9 with their positions symmetrical about the central axis of the threaded slide bar 7, it is beneficial to improve the ease of use of transport tanks of different sizes on the upper limit of the vehicle frame.

[0037] Among them, a connecting plate 10 is fixedly connected to the outer wall of the connecting frame 2, a connecting rod 11 is fixedly connected to the outer wall of the tractor frame 1 and inserted into the outer wall of the connecting plate 10, an insert rod 12 is inserted into the outer wall of the connecting plate 10 and inserted into the outer wall of the connecting rod 11, a first insertion hole 13 is opened at the connection part between the outer wall of the connecting plate 10 and the insert rod 12, and a second insertion hole 14 is opened at the connection part between the outer wall of the connecting rod 11 and the insert rod 12.

[0038] There are two sets of connecting plates 10. The spacing between the two sets of connecting plates 10 is adapted to the thickness of the connecting rod 11. There are two sets of both the connecting rod 11 and the connecting plate 10. The two sets of connecting rod 11 and connecting plate 10 are staggered with each other.

[0039] This facilitates the setting of connecting rod 11 and connecting plate 10, achieving the effect of pre-plugging and installing between vehicle frames.

[0040] Among them, the outer wall of the connecting rod 11 is provided with an electric push rod 15, one end of the electric push rod 15 is fixedly connected to a sliding rod 16, the outer wall of the sliding rod 16 is fixedly connected to a locking rod 17 that engages with the outer wall of the insertion rod 12, and a locking groove 18 is provided at the connection between the outer wall of the insertion rod 12 and the locking rod 17.

[0041] The design of the locking lever 17 and the locking slot 18 facilitates the easy locking and fixing of the insertion lever 12.

[0042] There are two sets of locking rods 17, and the positions of the two sets of locking rods 17 are symmetrical about the central axis of the sliding rod 16. The insertion rod 12 and the locking rod 17 are set in a one-to-one correspondence.

[0043] By setting two sets of locking rods 17 with their positions symmetrical about the central axis of the sliding rod 16, it is possible to improve the ease of assembly and use between frames.

[0044] Working principle: When using this double-trailer tanker truck, to improve the flexibility of clamping and fixing tanks of different sizes on the frame, the servo motor 5 is turned on. Through the rotation of the threaded rod 6, the threaded slide rod 7 slides along the inner wall of the fixing groove 8, and drives the clamping block 9 to slide synchronously. This allows the clamping block 9 to center and clamp the tank around its perimeter, thereby improving the ease of installation and use of tanks of different sizes on the frame.
