Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of brake drum, especially to a brake drum lifting appliance. BACKGROUND

[0002] The drum brake is used for making the brake shoe press the brake friction plate in the brake drum inside by the brake transmission mechanism, thereby generating the braking force, and making the wheel decelerate or parking in the shortest distance according to the need, so as to ensure the driving safety and guarantee that the automobile parking is reliable and cannot automatically slip. The large brake drum is large in shape and size, the brake drum diameter is about 500mm, and the weight is about 80kg, so the manpower cannot directly carry, and the travelling crane can only be used for lifting. The two sides of the brake drum are the heat dissipation hole and the mounting hole respectively, and the mounting hole diameter is smaller than the heat dissipation hole. In the prior art, the lifting appliance of F structure is clamped on the side wall of the brake drum, that is, the side of the heat dissipation hole. For example, the patent CN103626023B and the patent CN204737600U are used for the brake drum machining and the brake drum lifting of the 5-10T forklift respectively. However, the bowl opening of the brake drum needs to be upward, and the bottom needs to be upward for the staff to turn over, so as to lift, thereby increasing the working steps and physical consumption. The clamp structure is complex in the case that the bottom is upward, and the working efficiency is not high. SUMMARY

[0003] In view of the problems in the prior art, the utility model provides a brake drum lifting appliance, which solves the problem that the lifting appliance used when the mounting hole of the brake drum is upward is inconvenient to use.

[0004] According to the embodiment of the utility model, a brake drum lifting appliance, including connecting rod, sliding block, connecting rod and rotating rod, the connecting rod is vertically arranged, the top of connecting rod is provided with connecting ring, the midpoint position of rotating rod and the bottom end of connecting rod are rotatably connected, the rotating surface of rotating rod is vertical surface, the sliding block and connecting rod are slidably connected in the vertical direction, one end of connecting rod and sliding block are rotatably connected, the other end of connecting rod and rotating rod are slidably connected, and the rotating surface of connecting rod is parallel with the rotating surface of rotating rod;Positioning rod for fixing with connecting rod is arranged on sliding block.

[0005] The technical principle of the utility model is that the rotating rod at the bottom of the connecting rod is rotated to the inclined state and enters the inside of the brake drum from the hole at the top of the brake drum, then the rotating rod is rotated to the horizontal state by the sliding block and the connecting rod, and the two ends of the rotating rod abut against the two sides in the brake drum, so that the lifting can be carried out.

[0006] Preferably, the sliding block includes a connecting sleeve and a connecting block fixed to one side of the connecting sleeve. The connecting sleeve is sleeved on the connecting rod. The connecting block has a movable hole arranged laterally. The positioning rod is adapted to the movable hole. The connecting rod has a first positioning hole and a second positioning hole adapted to the positioning rod. The first positioning hole corresponds to the position of the upper end of the connecting rod when the rotating rod is in a horizontal state. The second positioning hole corresponds to the position of the upper end of the connecting rod when the rotating rod is in an inclined state.

[0007] Preferably, the top surfaces at both ends of the rotating rod are provided with anti-slip surfaces.

[0008] Preferably, the rotating rod has extension sections at both ends, and the extension sections and the ends of the rotating rod are connected by threads.

[0009] Preferably, the sliding block is provided with a gripping part.

[0010] Preferably, the rotating rod is provided with a scale.

[0011] Preferably, the end of the positioning rod is threadedly connected to the first positioning hole or the second positioning hole.

[0012] Compared with the prior art, the present invention has the following advantages: The present invention is simple to operate and convenient to use. By moving the sliding block in the vertical direction, the tilt angle of the rotating rod can be changed. When the tilt angle is large, the projection of the rotating rod on the horizontal plane is shortened, which makes it easier to enter the interior of the brake drum through the hole at the top of the brake drum. When the rotating rod is in a horizontal state, the projection of the rotating rod on the horizontal plane is extended, and the rotating rod can support and lift the side part of the brake drum hole.

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1As shown in the figure, this utility model embodiment proposes a brake drum lifting device, including a connecting rod 2, a sliding block 10, a connecting rod 7, and a rotating rod 8. The connecting rod 2 is vertically arranged, and a connecting ring 3 is provided at the top of the connecting rod 2. The midpoint of the rotating rod 8 is rotatably connected to the bottom end of the connecting rod 2, and the rotating surface of the rotating rod 8 is a vertical surface. The sliding block 10 and the connecting rod 2 are slidably connected in the vertical direction. One end of the connecting rod 7 is rotatably connected to the sliding block 10, and the other end of the connecting rod 7 is slidably connected to the rotating rod 8. The rotating surface of the connecting rod 7 is parallel to the rotating surface of the rotating rod 8. A positioning rod 9 is provided on the sliding block 10 for fixing to the connecting rod 2. In this embodiment, the lifting equipment is connected to the connecting ring 3. The rotating rod 8 enters the brake drum 1 from the mounting hole in an inclined state. Both ends of the rotating rod 8 abut against the inner side of the brake drum 1, so that the brake drum 1 moves stably. After the positioning rod 9 and the connecting rod 2 are connected, the sliding block 10 cannot move in the vertical direction, thereby preventing the rotating rod 8 from rotating and ensuring that the angle of the rotating rod 8 will not change during hoisting.

[0017] Preferably, the sliding block 10 includes a connecting sleeve 4 and a connecting block 5 fixed to one side of the connecting sleeve 4. The connecting sleeve 4 is sleeved on the connecting rod 2. The connecting block 5 has a horizontally arranged movable hole. The positioning rod 9 is adapted to the movable hole. The connecting rod 2 has a first positioning hole and a second positioning hole adapted to the positioning rod 9. The first positioning hole corresponds to the position of the upper end of the connecting rod 7 when the rotating rod 8 is in a horizontal state, and the second positioning hole corresponds to the position of the upper end of the connecting rod 7 when the rotating rod 8 is in an inclined state. In this embodiment, the first positioning hole corresponds to the fixed position of the connecting rod 7 when the rotating rod 8 is hoisted. When the lifting device is not in use, it is rotated to an inclined state to avoid occupying space. When the positioning rod 9 is inserted into the second positioning hole, it prevents the rotating rod 8 from rotating when the lifting device is moved, thus avoiding affecting safety.

[0018] Preferably, the top surfaces at both ends of the rotating rod 8 are provided with anti-slip surfaces. In this embodiment, the top surfaces at both ends of the rotating rod 8 are provided with rubber layers. When the rotating rod 8 supports the movement of the brake drum 1, it prevents one end of the rotating rod 8 from detaching from the brake drum 1 during lateral movement.

[0019] Preferably, the rotating rod 8 has extension sections at both ends, and the extension sections are threadedly connected to the ends of the rotating rod 8. When a larger brake drum 1 needs to be hoisted, the diameter of the mounting hole at the center of the brake drum 1 will also increase, and the extension sections ensure effective contact with the interior of the brake drum 1.

[0020] Preferably, the sliding block 10 is provided with a gripping part 6, which makes it easy for the operator to move the sliding block 10 in the vertical direction.

[0021] Preferably, the rotating rod 8 is equipped with a scale, which makes it easy for staff to check whether the lengths of both ends of the rotating rod 8 extending into the brake drum 1 and abutting against the brake drum 1 are consistent, thus ensuring stability when lifting the brake drum 1.

[0022] Preferably, the end of the positioning rod 9 is threadedly connected to the first positioning hole or the second positioning hole, and the threaded connection makes the rotating rod 8 more stable during hoisting.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
