Description

Technical Field

[0001] The utility model belongs to the technical field of electric transport vehicles, and in particular relates to a load hanging device for an electric transport vehicle. Background Art

[0002] An electric transport truck is a type of logistics handling equipment used for transporting cargo. It uses a battery as its power source, an electric motor as its motive force, and a gear transmission to drive the vehicle. The lifting of cargo is achieved by a DC motor and hydraulic transmission, which push the oil cylinder up and down to lift the cargo. Because both travel and lifting are electrically powered, the vehicle is driven by a standing-style driver and uses handlebars for steering. Therefore, it offers advantages such as labor-saving, high efficiency, smooth cargo handling, simple operation, safety, reliability, low noise, and zero pollution.

[0003] Problems with existing technologies:

[0004] When an electric transport truck is carrying items that are located above the operating range, it needs to use a load hanging device to carry out the carrying operation. When the hanging device used in conjunction with the electric transport truck rotates the hoisted heavy objects, it mostly relies on the operator to pull and brake, which causes the hung heavy objects to swing when placed on the electric transport truck, affecting the placement. Utility Model Content

[0005] The purpose of the utility model is to provide a load hanging device for an electric transport vehicle, which can solve the problem that when the electric transport vehicle is carrying items at a position higher than the use range, the load hanging device needs to be used in conjunction with the carrying operation.

[0011] During hoisting, the motor drives the reel to rotate and wind the rope to lift the load. At the same time, the reel pushes the second arc push plate on the torsion mechanism, so that the second arc push plate drives the brake plate on the translation disk to disengage from the brake hole, thereby releasing the brake of the reel, so that the hoisting operation can be carried out.

[0012] After the motor stops rotating, the winding wheel stops rotating synchronously, so that the second spring pushes the brake plate on the translation disk to insert into the brake hole, thereby forming a real-time braking effect on the winding wheel.

[0020] The beneficial effects are:

[0021] 1. The utility model can be installed and used with an electric transport vehicle through the first mounting plate and the second mounting plate. The use of the clamping hole plate and the brake column in combination can rely on manual operation to release the rotation restriction of the swivel support column. Then, after the swivel support column is rotated and adjusted, the brake column is pushed by the first spring to be inserted into the clamping hole on the clamping hole plate, thereby limiting the rotation of the swivel support column and the crossbeam plate, thereby improving the real-time braking effect after torsion, and also facilitating the placement of suspended heavy objects in combination with the electric transport vehicle.

[0022] 2. The utility model can release the brake when the winding wheel rotates by rotating and pushing the first arc push plate and the second arc push plate.

In this way, it is convenient to push the first push-pull plate 34 to drive the brake column 31 to move up and release the brake.

[0034] Furthermore, the first push-pull plate 34 is connected to the elastic pressing mechanism, and the elastic pressing mechanism includes a first spring 33, the first spring 33 is sleeved on the brake column 31, a baffle is fixed on the upper side of the brake column 31, and the baffle is rotatably coordinated with the first push-pull plate 34, a first fixed disk 32 is fixed on the brake column 31, the upper side of the first spring 33 is fixedly connected to the bottom surface of the push plate 3, and the lower side of the first spring 33 is fixedly connected to the first fixed disk 32.

[0035] Refer to the attached Figure 3 The power mechanism includes a winding wheel 41, which is rotatably connected to two first fixed plates 43.

The winding wheel 41 is provided with two winding grooves for winding the wire rope, so that the two ends of the lifting rope can be wound. Then, when lifting, the motor 42 is used to drive the winding wheel 41 to reel in the lifting rope, thereby achieving the effect of lifting.

[0036] Furthermore, the braking mechanism includes a braking hole 44 and a braking plate 49. The braking hole 44 is opened on the side of the winding wheel 41, and the braking hole 44 matches the braking plate 49. A rotating disk 45 is fixedly provided on one side of the winding wheel 41, and two symmetrically distributed first arc push plates 46 are fixedly provided on the side of the rotating disk 45. The braking plate 49 is sleeved in the second rotating shaft 47. The winding wheel 41 is correspondingly provided with a translation disk 410, and the translation disk 410 rotates in cooperation with the brake plate 49. Two symmetrically distributed second arc push plates 411 are fixed on the translation disk 410, and the second arc push plates 411 match the first arc push plates 46.

[0037] Furthermore, a second spring 412 is sleeved on the second rotating shaft 47 .

The limiting plate 416 corresponds vertically to the rotating baffle 414. With this arrangement, when the winding wheel 41 rotates, the brake plate 49 and the second rotating shaft 47 can be driven to rotate, and the rotating disk 45 The first arc push plate 46 on the translation disk 410 pushes the second arc push plate 411 on the translation disk 410, thereby pushing the translation disk 410 and the brake plate 49 away from the winding wheel 41, so that the brake plate 49 can be released from the socket restriction with the brake hole 44, and at the same time, the second rotating shaft 47 drives the rotating baffle plate 414 on the second fixed disk 413 to rotate and contact with the limiting plate 416 to form a rotation restriction, so that after the winding wheel 41 stops rotating, the torsion spring 415 drives the second fixed plate 48 and the second rotating shaft 47 to rotate in the opposite direction and return to the original position, and at the same time, the second spring 412 also pushes the brake plate 49 to socket with the brake hole 44 to form a brake.

At the same time, the upward movement of the brake column 31 drives the first fixed plate 43 to squeeze the first spring 33, so that after the rotating support column 1 is rotated to the appropriate position, the brake column 31 is immediately pushed down and inserted into the corresponding clamping hole on the clamping hole plate 2 to brake.

[0040] During hoisting, the motor 42 drives the reel 41 to rotate and wind the rope to lift the object. At the same time, the reel 41 pushes the second arc push plate 411 on the torsion mechanism, so that the second arc push plate 411 drives the brake plate 49 on the translation disk 410 to disengage from the brake hole 44, thereby releasing the brake of the reel 41, so that the hoisting operation can be carried out.

[0041] After the motor 42 stops rotating, the winding wheel 41 stops rotating synchronously, so that the second spring 412 pushes the brake plate 49 on the translation disk 410 to be inserted into the brake hole 44, thereby forming a real-time braking effect on the winding wheel 41.

[0042] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
