DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0023] As Figure 1 shown, a mold insert lifting trolley of a preferred embodiment of the present utility model includes a support frame 1. A placement frame 2 is provided on one side of the support frame 1. The placement frame 2 is provided with a first placement position for placing old inserts and a second placement position for placing new inserts. A lifting arm 3 is provided at the upper end of the support frame 1. A hoisting winch 4 is movably provided on the lifting arm 3. Both the support frame 1 and the placement frame 2 can be made of aluminum, so as to reduce the weight of the entire trolley.

[0024] Based on the above technical features, for the mold insert lifting trolley, by providing a placement frame 2 on one side of the support frame 1, and providing a first placement position for placing old inserts and a second placement position for placing new inserts on the placement frame 2. At the same time, a lifting arm 3 is provided at the upper end of the support frame 1, and a hoisting winch 4 is movably provided on the lifting arm 3. When the insert needs to be replaced, first extend the hoisting winch 4 into the interior of the equipment through the lifting arm 3, then connect the hoisting winch 4 to the insert, and then move the hoisting winch 4, and hoist the old insert into the first placement area, and then hoist the new insert in the second placement position into the interior of the equipment for installation, thus realizing the lifting and replacement of the insert, which not only simplifies the operation process, but also does not require manual replacement, avoiding burns caused by high temperature and sprains caused by heavy object handling, and ensuring personnel safety.

[0025] Connecting rods 7 are respectively provided on both sides of the upper end of the support frame 1. The connecting rods 7 are perpendicular to the support frame 1. The lifting arm 3 is connected to the free ends of the two connecting rods 7. The length of the connecting rod 7 can be approximately half of the width of the placement frame 2, so that the lifting arm 3 is approximately located on the axis of symmetry of the placement frame 2, which is convenient for placing the old insert into the first placement position and also convenient for hoisting the new insert.

[0026] Please refer to the attached Figure 2 drawing. In this embodiment, a moving trolley 5 is movably provided on the lifting arm 3. The hoisting winch 4 is connected to the moving trolley 5, so as to realize the movement of the hoisting winch 4 through the movement of the moving trolley 5, and ensure the smooth movement of the hoisting winch 4 after hoisting the insert.

[0027] Meanwhile, to prevent the moving trolley 5 from falling off during movement, the cross-section of the lifting arm 3 is in the shape of an I-beam, including a top plate and a bottom plate arranged opposite to each other. A connecting plate is connected between the bottom plates. The top plate is connected to the support frame 1, and the moving trolley 5 moves along the bottom plate. Thus, the lifting arm 3 can be directly made of an I-beam. The corresponding moving trolley 5 includes a vehicle body 51. Two groups of wheels 52 are oppositely arranged on the vehicle body 51. The wheels 52 are arranged on the bottom plate, and the connecting plate is located between the two groups of wheels 52. Thus, under the action of the connecting plate, the moving trolley will always move on the bottom plate. After the moving trolley 5 is installed, anti-detachment plates can be arranged at both ends of the lifting arm 3 to prevent the moving trolley 5 from falling off.

[0028] In this embodiment, the hoisting pulley 4 can directly use an electric hoist or a manual hoist. When using a manual hoist, a driving mechanism for driving its rotation is connected to the hand-pulled hoist. That is, the driving mechanism drives the hook of the hand-pulled hoist to move up and down. The driving mechanism can use a motor, an electric drill, etc., and needs to have a forward and reverse function.

[0029] In addition, to cooperate with the connection between the hook of the hoisting pulley 4 and the insert, a lifting tool can be set. The lifting tool includes a suspension rod. First hooks for connecting with the insert are arranged at both ends of the suspension rod, and a second hook for connecting with the hoisting pulley is arranged in the middle of the suspension rod, so as to facilitate the quick connection between the hoisting pulley 4 and the insert.

[0030] Please refer to the atta Figure 3 , in this embodiment, the placement rack 2 includes a rack body 21. A placement plate 22 is arranged in the middle of the rack body 21. The placement plate 22 forms the first placement position. A drawer 23 is movably arranged at the upper end of the rack body 21. The inside of the drawer 23 forms the second placement position. When an old insert needs to be placed in the first placement position, push the drawer 23 to make the first placement position communicate with the upper end of the rack body 21, which is convenient for placing the old insert. After the old insert is placed, push the drawer 23 in the reverse direction to make the drawer 23 located directly above the old insert, thereby blocking the communication between the first placement position and the upper end of the rack body 21, that is, closing the first placement position. Thus, the drawer 23 and the rack body 21 together play a role of a protective heat-insulating cover for the old insert.

[0031] Meanwhile, to facilitate the movement of the drawer 23, guide rails 24 are respectively arranged on both sides of the upper end of the rack body 21. Sliding grooves 25 are respectively arranged on both sides of the bottom of the drawer 23. The sliding grooves 25 correspond to the guide rails 24 one by one, and the sliding grooves 25 are slidably connected to the guide rails 24. Meanwhile, a handle can be arranged at one end of the drawer 23. Push and pull the drawer 23 through the handle, which is convenient for applying force to the drawer 23.

[0032] In this embodiment, rollers 6 are respectively provided at the four corners of the bottom of the placement rack 2, so as to facilitate the movement of the trolley and facilitate the extension or retraction of the lifting arm 3 into or out of the interior of the equipment. Preferably, the rollers 6 include two universal wheels provided on both sides of one end of the placement rack 2 and two directional wheels provided on both sides of the other end of the placement rack 2. Through the cooperation of the universal wheels and the directional wheels, it is convenient to control the direction of the trolley and the safety factor can be improved.

[0033] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
