Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a new type of protective cover for quickly replacing a hook head. Background Art

[0002] The pulley block is a simple machine composed of multiple movable pulleys and fixed pulleys. It can save effort and change the direction of force. The movable pulley block has many pulleys, so a protective cover is needed to protect the movable pulley block and limit the wire rope.

[0003] A pulley is a small wheel with grooves around it that can rotate around an axis. A simple machine that can rotate around a central axis is called a pulley, which consists of a grooved disc that can rotate around a central axis and a flexible cable (rope, tape, steel cable, chain, etc.) that crosses the disc.

[0004] At present, when the movable pulley block or the hook head is replaced, the guard cannot be taken down through the wire rope. Each time the movable pulley block is replaced, the wire ropes on the drum and the movable pulley block must be completely removed, and then the wire ropes are passed through each pulley piece of the movable pulley block one by one. This method is time-consuming, labor-intensive and labor-intensive.

[0005] Therefore, there is an urgent need to design a new type of protective cover for quickly replacing the hook head to solve the problem that the existing movable pulley block or hook head needs to be completely disassembled when replacing the wire rope, which is time-consuming, labor-intensive, inefficient and labor-intensive. Utility Model Content

[0006] In view of the problems existing in the prior art, the utility model aims to provide a new type of protective cover for quickly replacing the hook head.

[0007] The technical solution adopted by the utility model to solve the technical problem is: a new type of protective cover for quickly replacing the hook head, comprising a protective cover and a hook head, wherein the protective cover is provided with a protective cover hole and a wire rope sliding hole, the wire rope sliding hole is connected to the protective cover hole, the wire rope sliding hole is connected to the outer side of the mounting plate of the protective cover, and the wire rope slides out of the wire rope sliding hole to the outer side of the protective cover.

[0008] Specifically, a mounting plate is provided on one side of the shield, and a plurality of bolt holes are provided on the mounting plate.

[0009] Specifically, the bolt holes of the shield are connected to the fixed plate of the movable pulley block through bolts, and a hook head is installed at the bottom of the fixed plate of the movable pulley block.

[0010] Specifically, shield holes are arranged on two sides of the shield opposite to each other, and a steel wire rope is installed on the movable pulley.

[0011] Specifically, the shield hole includes shield hole one and shield hole two, and two wire rope sliding holes are also relatively arranged.

[0012] Specifically, the wire rope sliding hole is connected to the shield hole 1 and the shield hole 2 on the same side, and the wire rope sliding hole is connected to the outer side of the shield mounting plate.

[0013] The utility model has the following beneficial effects:

[0014] The utility model discloses a new type of protective cover for quickly replacing the hook head, and transforms the protective cover of the movable pulley block. The steel wire rope directly slides out of the protective cover through the steel wire rope sliding hole, so that the steel wire rope is freed from the protective cover and the movable pulley block. The steel wire rope does not need to be completely removed from the drum, and the movable pulley block can be quickly replaced, which saves time, saves effort, improves work efficiency, and greatly reduces work intensity.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely further describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1:

[0021] like Figure 1-2 As shown, a new type of protective cover for quickly replacing a hook head includes a protective cover 1, a wire rope 2 and a hook head 3. The protective cover 1 is provided with a protective cover hole, a wire rope sliding hole 1.3 and a bolt hole 1.4. The wire rope sliding hole 1.3 is connected to the upper part of all the protective cover holes, and the wire rope sliding hole 1.3 is connected to the outer side of the mounting plate of the protective cover 1. The wire rope 2 slides out from the wire rope sliding hole 1.3 to the outer side of the protective cover 1.

[0022] A mounting plate is provided on one side of the shield 1, and a plurality of bolt holes 1.4 are provided on the mounting plate.

[0023] The bolt holes 1.4 of the shield 1 are connected to the fixed plate of the movable pulley block through bolts, and the hook head 3 is installed at the bottom of the fixed plate of the movable pulley block.

[0024] Shield holes are arranged opposite to each other on both sides of the shield 1. The number of the shield holes is the same as the number of movable pulleys of the movable pulley block. Steel wire ropes 2 are installed on the movable pulleys.

[0025] The shield holes include shield hole 1.1 and shield hole 2 1.2. Two wire rope sliding holes 1.3 are also arranged opposite to each other. The wire rope sliding holes 1.3 on the same side are connected to the shield hole 1.1 and the shield hole 2 1.2 on the same side. The wire rope sliding holes 1.3 are connected to the outside of the shield 1 mounting plate, so that the wire rope 2 passes through the shield 1 through the wire rope sliding holes 1.3.

[0026] Embodiment 2: Specific implementation process of the new type of protective cover for quickly replacing the hook head using the structural form of embodiment 1:

[0027] 1. Punch the holes of the old movable pulley block shield to the edge of the shield, and do the same work symmetrically on the back of the shield, so that the shield 1 can be taken down through the wire rope 2. Use the same method to remove the shields 1 at both ends of the new movable pulley block, so that the wire rope 2 is separated from the old movable pulley block. At this time, be sure to mark the position of the wire rope, and hang the wire ropes on the four pulleys of the new movable pulley block in turn, and finally install the new and old shields.

[0028] 2. The modification of the guard 1 does not affect the anti-slip function. The old guard is taken down through the wire rope 2 to separate the wire rope 2 from the old movable pulley block. At this time, the position of the wire rope 2 must be marked. Similarly, the guards 1 at both ends of the new movable pulley block are removed. The cutting size and position are the same as the old guard. The wire ropes 2 are hung on the pulleys of the new movable pulley block in turn, and the two new guards 1 that have been cut are installed through the wire rope 2.

[0029] A new type of protective cover for quickly replacing hook heads is provided. The protective cover 1 of a movable pulley block is modified. The movable pulley block can be quickly replaced without completely removing the steel wire rope 2 from the drum. The time required is short, effort is saved, working efficiency is improved, and working intensity is greatly reduced.
