Problems solved by technology

[0003] The field environment conditions are poor and there is no trench. When disassembling the gearbox, people need to walk on the ground below, and 2~3 people need to use ropes or hand hoists to lift it up. First remove the drive shaft and gearbox fixing bolts, then pry them out, and then move them to The exterior of the vehicle is slowly placed on the ground. The whole process requires the cooperation of multiple people, and the labor intensity is high. Disassembly and assembly account for most of the workload of the entire maintenance, and there are great safety hazards

Embodiment 1

[0028] Embodiment one, such as figure 1 , figure 2 As shown, a kind of multi-purpose hanger comprises cross beam 1, and described cross beam 1 is provided with slide block 2 that can slide axially along cross beam 1, and described slide block 2 is equipped with a No. 1 pulley 3, and described No. 1 pulley 3 A hoisting chain 4 is wound around it, and one end of the hoisting chain 4 is connected to a hook 5 , and the other end is connected to a manual hoist 6 . The beam 1 of the first embodiment is placed above the gearbox, the manual hoist 6 is used as the power to hoist the gearbox, the height difference between the beam and the hook 5 is reduced by the No. 1 pulley 3, and the gearbox is moved by the horizontal movement of the slider 2. To the outside of the vehicle, the whole process can be completed by only one person, which is easy, fast and safe, and is especially suitable for the disassembly and assembly of large vehicle gearboxes in the field environment.

Embodiment 2

[0034] Embodiment two, such as image 3 , Figure 4 As shown, at least two lifting buckles 17 movable in the axial direction are provided on the outside of the beam 1 , and a height-adjustable hook 18 is arranged above the lifting buckles 17 . The hoisting buckle 17 of the second embodiment is slidable, and the height of the hook 18 is adjustable. It is suitable for a gearbox with a mandrel on the top. The hook 18 is hung on the mandrel to complete the fixed installation of the beam 1 .

[0035] Embodiment two, such as image 3 , Figure 4 As shown, a screw 19 is hinged above the hoisting buckle 17, and a hook 18 and a stop nut 20 are sequentially mounted on the screw 19. In the second embodiment, other structures can also be selected to realize the adjustment of the height of the hook 18 .

Embodiment 3

[0036] Embodiment three, such as Figure 5 As shown, the suspension hook 5 is a double-chain suspension hook. Compared with the single-chain hook, the double-chain hook of Embodiment 3 is more labor-saving, and is suitable for particularly heavy gearboxes.

Abstract

The invention discloses a multipurpose hoisting frame which is used for reducing labor intensity of disassembling a large vehicle gearbox outdoors and meanwhile improves efficiency. The multipurpose hoisting frame comprises a beam which is provided with a sliding block capable of sliding along the beam axially. A first pulley is installed on the sliding block. A hoisting chain winds around the first pulley. A hoisting hook is connected to one end of the hoisting chain, and a hand-drive block is connected to the other end of the hoisting chain. According to the multipurpose hoisting frame, the hand-drive block is adopted as power for hoisting the gearbox, the first pulley is utilized for reducing the height difference between the beam and the hoisting hook, the sliding block moves horizontally to move the gearbox out of a vehicle, only one person is needed to carry out operation to complete the whole process, the operation is easy, fast and safe, and the multipurpose hoisting frame is particularly suitable for assembling and disassembling the large vehicle gearbox in a field environment.

Description

technical field [0001] The invention relates to the field of large-scale vehicle maintenance technology and equipment, in particular to a multi-purpose hanger. Background technique [0002] Large-scale vehicles need to change gears frequently on muddy or potholed roads, and the transmission and clutch parts have a high failure rate. Considering factors such as the transportation cost of the faulty vehicle and the progress of the project, small faults of this type of vehicle are generally repaired on site. The gearboxes of large vehicles are large and heavy, and the gearboxes of some large trucks are even more than 0.5 tons. [0003] The field environment conditions are poor and there is no trench. When disassembling the gearbox, people need to walk on the ground below, and 2~3 people need to use ropes or hand hoists to lift it up. First remove the drive shaft and gearbox fixing bolts, then pry them out, and then move them to The exterior of the vehicle is slowly placed on t...
