Description

Technical Field

[0001] The utility model relates to a tank back rack of a tank back vehicle, belonging to the technical field of accessory parts of tank back vehicles. Background Art

[0002] Tank-carrying trucks are a common type of bulk mobile silo transfer vehicle currently on the market. The main function of tank-carrying trucks is to transport bulk mobile silos (dry-mixed mortar for engineering, cement ash for oilfield cementing, water and other materials) between construction sites. Bulk mobile silos can be empty tanks or loaded with a certain amount of materials. Through the coordinated action of the hydraulic system and the back frame, the vehicle can automatically lift the bulk mobile silo and place it longitudinally on its own frame to realize the transportation of the bulk mobile silo. After transporting the bulk mobile silo to the designated location, the bulk mobile silo can be automatically unloaded and placed on the ground. The back tank frame of the existing tank-carrying truck, such as the tank-carrying truck disclosed in the utility model patent with authorization announcement number CN216636295U, can meet the needs of use to a certain extent, but it has the following problems:

[0003] First, the connecting fork on the existing tank carrier back rack is directly driven and moved by a hydraulic cylinder, which has the problem of high energy consumption caused by lack of effort.

[0004] Second, the positioning part on the top of the existing tank-carrying rack is fixedly arranged. When it is fixedly arranged, it can only meet the transportation work of a single type of silo, and there is a problem of a small number of transportation types.

[0005] Therefore, it is necessary to develop a new back tank rack of a back tank vehicle to solve the above problems of the existing back tank rack. Summary of the invention

[0006] The utility model aims to provide a tank carrier for a tank truck with a compact structure and ingenious design to solve the problems of high energy consumption and relatively few transport models of existing tank carriers.

[0007] The technical solution of the utility model is:

[0008] A tank-carrying rack of a tank-carrying truck comprises an assembly beam, a supporting arc plate, a limiter, a fixed pulley, a movable pulley, a control cylinder, a steel wire rope, a rotating swing arm and a mounting plate; the characteristics are as follows: a plurality of supporting arc plates are fixedly installed at intervals between two symmetrically arranged groups of assembly beams; a limiter is installed on the inner side of one end of the assembly beam; a rotating swing arm is installed on the middle part of the assembly beam through an inclined sliding hole and a sliding pin; the upper end of the rotating swing arm is hingedly connected to the mounting plate; a movable pulley is installed on the assembly beam on one side of the rotating swing arm through a control cylinder; two groups of fixed pulleys are installed on the upper and lower ends of the assembly beam on one side of the movable pulley; after one end of the steel wire rope is connected to the assembly beam, the other end is fixedly connected to one end of the mounting plate after passing through the fixed pulley, the movable pulley and the fixed pulley in sequence.

[0009] A mounting hook is arranged on one side of the mounting plate.

[0010] The limiter includes a mounting seat, a slide, a baffle, a fastener and a clamping block; the mounting seat is installed on the inner side of one end of the assembly beam; the slide is slidably mounted on the mounting seat through a slide groove; the bottom end of the slide is equipped with a clamping block through a fastener; and the top end of the slide is equipped with a baffle.

[0011] A layer of rubber pad is arranged on the surface of the baffle.

[0012] The advantages of the utility model are:

[0013] The tank rack of the tank truck has a compact structure and ingenious design. It adopts a technical solution of cooperating movable pulleys and fixed pulleys to pull the mounting plate, thereby achieving the purpose of saving labor, thereby solving the problem of high energy consumption of existing tank racks and being particularly suitable for the use requirements of tank trucks.

[0025] The tank carrier of the tank carrier vehicle includes an assembly crossbeam 1, a supporting arc plate 2, a stopper 3, a fixed pulley 10, a movable pulley 9, a control cylinder 8, a wire rope 19, a rotating swing arm 6 and a mounting plate 7 (see the attached manual). Figure 1 , 2 and 3).

[0026] A plurality of supporting arc plates 2 are fixedly installed between two symmetrically arranged groups of assembly beams 1; the bottom ends of the two groups of assembly beams 1 are hingedly connected to the tanker truck; when working, under the action of the tanker truck's hydraulic system, it can push the assembly beams 1 to rotate around the hinge point.

[0027] When the tank body is placed on the tank backing rack, the supporting arc plate 2 can provide support for the tank body.

[0028] A limiter 3 is installed inside one end of the assembly beam 1 (see the appendix of the instruction manual). Figure 2 and 3 The stopper 3 includes a mounting seat 12, a slide 14, a baffle 17, a fastener 15 and a pressing block 16 (see the attached manual). Figure 5 and 6 ).

[0029] A mounting seat 12 is installed inside one end of the assembly crossbeam 1; a slide 14 is slidably mounted on the mounting seat 12 through a slide slot 13; a pressing block 16 is mounted on the bottom of the slide 14 through a fastener 15; and a baffle 17 is installed on the top of the slide 14. A layer of rubber pad 18 is provided on the surface of the baffle 17 (see the attached manual Figure 5 and 6 ).

[0030] The purpose of setting the stopper 3 is that during operation, the position of the carriage 14 can be adjusted along the slide groove 13 after loosening the fastener 15 according to the specifications of the tank. When the carriage 14 is adjusted to a suitable position, the baffle 17 can be moved to a suitable position by tightening the fastener 15. In this way, the baffle 17 can be moved to a suitable position to adapt to the use of various tanks.

[0031] The middle part of the assembly crossbeam 1 is provided with a rotating swing arm 6 through an inclined sliding hole 4 and a sliding pin 5; the upper end of the rotating swing arm 6 is hingedly connected to a mounting plate 7; a mounting hook 11 is provided on one side of the mounting plate 7 (see the attached manual). Fig. 9 ).

[0032] A movable pulley 9 is installed on the assembly beam 1 on one side of the rotating swing arm 6 through a control cylinder 8; two sets of fixed pulleys 10 are installed on the upper and lower ends of the assembly beam 1 on one side of the movable pulley 9; after one end of the steel wire rope 19 is connected to the assembly beam 1, the other end passes through the fixed pulley 10, the movable pulley 9 and the fixed pulley 10 in sequence and is fixedly connected to one end of the mounting plate 7 (see the attached manual). Figure 1 and 10 ).

[0033] When the tank carrier of the tank carrier is in operation, when it rotates to a vertical state, the control cylinder 8 gradually loosens the wire rope 19, and at this time, the bottom end of the rotating swing arm 6 slides to the bottom end of the inclined sliding hole 4 under the guidance of the sliding pin 5 (see the attached manual). Fig.10 ), at the same time, due to the loosening of the wire rope 19, the rotating swing arm 6 will drive the mounting plate 7 to rotate to a downward tilted state (see the attached manual Fig.10 ). When the tank back rack rotates to a vertical state and fits the tank body, the control cylinder 8 gradually tightens the wire rope 19. During the tightening process of the wire rope 19, it will drive the mounting plate 7 and the rotating swing arm 6 to rotate upward, and finally hook the hanging ear of the tank body through the mounting hook 11. Then, the mounting plate 7 will drive the tank body to move upward through the hanging ear under the traction of the wire rope 19. When the top of the tank body contacts the baffle 17, the tank body stops moving upward. At this time, the tank body is fixed with the tank back rack under the action of the mounting plate 7, and then the tank back rack can drive the tank body to rotate to a horizontal state and place it on the tank back truck.

[0034] The tank back rack of the tank back truck has a compact structure and ingenious design. It adopts the technical solution of the movable pulley 9 and the fixed pulley 10 to pull the mounting plate 7, thereby achieving the purpose of saving labor, thereby solving the problem of high energy consumption of the existing tank back rack and being particularly suitable for the use requirements of the tank back truck.
