Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle box enclosure hoisting, in particular to a special hoisting device for a dump truck vehicle box enclosure. Background Art

[0002] A dump truck is a vehicle that unloads cargo by itself through hydraulic or mechanical lifting, also known as a tipper.

[0003] The U-shaped dump truck body is a one-piece structure made of high-strength steel plates. Compared with traditional rectangular dump trucks, the U-shaped body has the following significant advantages: Lightweight: U-shaped bodies are usually made of high-strength steel plates, and the plate thickness is 20% lower than that of rectangular dump trucks, which reduces the body weight and effectively improves the load utilization factor; Beautiful and wear-resistant design: The U-shaped body is not only beautiful in appearance, but also made of high-strength mining vehicle materials with good wear and impact resistance, which reduces deformation of the cargo body and prolongs its service life; Clean unloading: The bottom of the U-shaped body has an inverted trapezoidal design, which helps to better tilt engineering sand and gravel cargo, and is less likely to cause adhesion during unloading, making unloading cleaner; High flexibility: The U-shaped body design makes the vehicle more stable during driving and has a lower center of gravity, especially suitable for conditions that require frequent turns and operation in confined spaces; Easy cleaning: The U-shaped body design facilitates cleaning after transportation operations, especially for some clay cargoes, without the need for a hoe or shovel.

[0004] The coaming is the standard configuration of the U-shaped dump truck body. Its structure is as follows Figure 3-4 As shown, the continuously curved plate structure serves as a protective barrier to prevent spilled materials from falling in front of and behind the tires. When installing the panel, it must be welded upright to the vehicle's interior. The front end of the panel is welded to the front plate, the rear end to the column, and the center section is welded to the vehicle's interior via a triangular plate.

[0005] At present, welding process lifting ears are used for hoisting operations of the hoisting panels. Specifically, the process lifting ears are spot-welded in the middle of the hoisting panels. After the crane chain lifts the panels, the operator welds the panels to both sides of the car body. Finally, the process lifting ears are knocked and polished off. This can easily cause mechanical damage such as dents and scratches to the car body panels. The operator needs to perform secondary grinding and shaping on the damaged parts of the panels, which not only increases the workload and reduces the working efficiency, but also affects the overall aesthetics of the box body due to the repair. Utility Model Content

[0006] In order to solve the problem that the traditional method of using welding technology to lift the lugs for the enclosure hoisting operation not only increases the workload and reduces the working efficiency, but also affects the overall aesthetics of the box due to the repair, the utility model provides a special hoist for the enclosure of the dump truck box.

[0007] The utility model is realized through the following technical solutions:

[0008] A special lifting device for the body panel of a dump truck comprises a U-shaped suspension frame and two U-shaped support frames arranged symmetrically on the left and right. A lifting ring is connected to the middle part of the horizontal section of the suspension frame. The end of an upright section of the support frame is connected to a connecting rod which is rotatably connected to the upright section of the suspension frame. The connecting rod is inclined toward the other upright section of the support frame. The horizontal section of the support frame is used to support the bottom of the body panel, and the end of the other upright section of the support frame and the end of the upright section of the suspension frame can clamp and limit the body panel.

[0009] A further improvement of the present invention is that screws are screwed through the left and right upper parts of the support frame, and the support frame also includes a sleeve that can be connected to the end of the screw, and a support plate that can abut against the rib plate of the enclosure body is provided on the sleeve.

[0010] A further improvement of the present invention is that the sleeve is screwed to the end of the screw rod.

[0011] A further improvement of the present invention is that an operating hole is provided at the end of the screw.

[0012] A further improvement of the present invention is that the operating hole is a hexagonal hole or a square hole.

[0013] A further improvement of the present invention is that the end of the vertical section of the suspension frame and the end of the corresponding vertical section of the support frame are in a matching inclined surface.

[0014] A further improvement of the present invention is that a first protective pad is provided at the inclined surface of the vertical section of the suspension frame.

[0015] A further improvement of the present invention is that a second protective pad is provided at the inclined surface of the upright section of the support frame.

[0016] A further improvement of the present invention is that the two support frames are connected by a cross bar.

[0017] A further improvement of the present invention is that the connecting rod and the upright section of the suspension frame are rotatably connected and installed via a rotating pin, and a gasket is installed on the rotating pin and is penetrated by a cotter pin.

[0018] It can be seen from the above technical solutions that the beneficial effects of the present invention are:

[0019] When in use, the support frame is inserted into the panel body, so that the first and second panels are placed in the support frame, the crane is mounted with a lifting ring, and the panel body is lifted by its own weight, so that the first panel is supported by the horizontal section of the support frame, the lower side of the third panel is supported by the upper end of the front vertical section of the support frame, and the upper side of the third panel is pressed by the lower end of the vertical section of the suspension frame, thereby achieving stable lifting of the panel body, which can facilitate the welding of the panel body. The overall structure is simple, easy to use, and practical. It is efficient in lifting and welding the panel body. After welding is completed, this special lifting device can be easily disassembled, effectively avoiding the removal and repair of the lifting lugs in the welding process, which affects the aesthetics of the panel body.

[0026] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0027] like Figure 3-4 The figure shows a schematic diagram of the structure of the enclosure body 1; it includes a first plate surface 11, a second plate surface 12, a third plate surface 13, and a fourth plate surface 14 which are bent in sequence, and the first plate surface 11 is bent at a right angle to the second plate surface 12, the third plate surface 13 is bent at an obtuse angle to the second plate surface 12, specifically 150 degrees, and the fourth plate surface 14 is bent at an obtuse angle to the third plate surface 13, specifically 165 degrees; a number of ribs 15 are provided at intervals on the front and rear sides of the inner sides of the fourth plate surface 14 and the third plate surface 13.

[0028] like Figure 1-2 As shown, the utility model discloses a special lifting device for the body panel of a dump truck, comprising a U-shaped suspension frame 2 and two U-shaped support frames 3 symmetrically arranged front and back, a lifting ring 10 is connected to the middle part of the horizontal section (left and right direction) of the suspension frame 2, and the upper end part of the rear vertical section of the support frame 3 is connected to a connecting rod 4 rotatably connected and installed with the vertical section of the suspension frame 2, and the connecting rod 4 is inclined toward the other vertical section of the support frame 3; the horizontal section (front and back direction) of the support frame 3 is used to support the first plate surface 11 at the bottom of the body panel 1, and the upper end part of the front vertical section of the support frame 3 and the lower end part of the vertical section of the suspension frame 2 can clamp and limit the third plate surface 13 of the body panel 1.

[0029] When in use, the support frame 3 is inserted into the panel body 1, so that the first panel surface 11 and the second panel surface 12 are placed in the support frame 3 (the middle part of the panel body 1 is supported and hoisted by the two support frames 3), the crane is hung with the lifting ring 10, and the panel body 1 is lifted by its own weight, so that the first panel surface 11 is supported by the horizontal section of the support frame 3, the lower side of the third panel surface 13 is supported by the upper end of the vertical section of the support frame 3, and the upper side of the third panel surface 13 is pressed by the lower end of the vertical section of the suspension frame 2, as shown in FIG. Figure 2 As shown, the stable hoisting of the panel body 1 is achieved, so that the welding operation of the panel body 1 can be easily realized.

The corresponding inclined surface matches the inclination angle of the third plate surface 13 of the panel body 1, achieving the reliability of the clamping of the panel body 1.

[0035] Furthermore, a first protective pad 21 is provided at the lower inclined surface of the vertical section of the hanger frame 2. A second protective pad 31 is provided at the upper inclined surface of the front vertical section of the support frame 3. Both the first and second protective pads 21 and 31 are made of rubber. These pads effectively increase the secure clamping of the third panel 13 and prevent damage and wear to the enclosure body 1.
