Description

Technical Field

[0001] This utility model relates to the field of lifting frame technology, specifically to an extrusion die head lifting frame. Background Technology

[0002] In the industrial production sector, with industry development and technological advancements, labor costs are constantly increasing while product profit margins are gradually decreasing. To enhance market competitiveness, companies are committed to reducing production costs. Traditional lifting frames present numerous problems in the hoisting, installation, and dismantling of extrusion die heads. Because extrusion die heads are cylindrical, using ordinary lifting frames makes it difficult to accurately hoist them into the equipment holes. This not only results in high labor intensity but also increases the risk of the die head slipping and falling during hoisting, potentially causing damage to the die head and injuries to personnel.

[0003] Therefore, designing a lifting frame that can quickly and smoothly lift the extrusion die head has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] Multiple rollers are rotatably mounted on an arc-shaped frame at intervals and within the arc-shaped spatial region;

[0008] Multiple lifting rings are installed at both ends of the arc-shaped frame.

[0009] Furthermore, the arc-shaped frame includes:

[0010] Two identical arc-shaped strips;

[0011] Two horizontal bars connect the two ends of two curved strips to form an arc-shaped frame.

[0012] Furthermore, the crossbar and the arc-shaped strip are connected by screws.

[0013] Furthermore, each crossbar is equipped with two hanging rings.

[0014] Furthermore, multiple rollers are installed at equal intervals.

[0015] Further, the roller includes:

[0016] The unloading roller has a through hole at both ends, and stepped circular grooves are provided at both ends of the through hole;

[0017] Two bearings are fitted one-to-one into two stepped circular grooves;

[0018] A long screw and a nut are used to mount the unloading roller onto the arc-shaped frame, and the unloading roller can rotate around the long screw as an axis.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The extrusion die head lifting frame of this utility model has the following significant advantages:

[0020] Firstly, its simple structure and convenient operation greatly reduce the labor intensity of operators.

[0021] Secondly, the arc-shaped structure of the hoisting frame is compatible with the shape of the cylindrical extrusion head, and can fit the extrusion head well.

[0022] Third, the multiple unloading rollers evenly arranged on the lifting frame can evenly distribute the force when lifting the extrusion head, thus making the lifting frame lift the extrusion head more stably.

[0023] Fourth, using this lifting frame for the lifting of extrusion heads is convenient, stable, and fast, effectively reducing the time required for the installation, disassembly, and maintenance of extrusion heads, lowering production costs, and improving the company's economic benefits.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] Example 1: The specific structure of this utility model is as follows:

[0029] Please refer to the appendix. Figure 1 The present invention provides a lifting frame for an extrusion die head, comprising:

[0030] An arc-shaped frame 6 has an arc-shaped space; the arc-shaped frame 6 includes two arc-shaped strips 6 with identical structures and two crossbars 2. The two crossbars 2 connect the two ends of the two arc-shaped strips 6 to form an arc-shaped frame; the crossbars 2 and the arc-shaped strips 6 are connected by screws 3; the arc-shaped strips 6 and the crossbars 2 are both square strips;

[0031] Multiple rollers 7 are rotatably mounted on the arc-shaped frame 6 at intervals and within the arc-shaped spatial region;

[0032] Multiple lifting rings 1 are installed at both ends of the arc-shaped frame 6, with each crossbar 2 equipped with 2 lifting rings 1.

[0033] Multiple rollers are installed at equal intervals, such as... Figure 1 As shown, there are 3 rollers 7, one of which is located at the bottom of the arc-shaped space.

[0034] The roller 7 includes:

[0035] The unloading roller has a through hole at both ends, and stepped circular grooves are provided at both ends of the through hole;

[0036] Two bearings 4 are fitted one-to-one into two stepped circular grooves;

[0037] A long screw and a nut are used to mount the unloading roller onto the arc-shaped frame 6, and the unloading roller can rotate around the long screw as an axis.

[0038] Example 2:

[0039] When using the extrusion die head lifting frame of this utility model for extrusion die head installation, first place the extrusion die head on the lifting frame, then use a crane or other lifting equipment to hook the lifting ring 1 and slowly raise the lifting frame to the corresponding height for extrusion die head installation. Next, slowly move the frame horizontally towards the corresponding installation hole on the extrusion die head. Once it reaches the correct position, tighten the screws to complete the installation. Because the extrusion die head is cylindrical and the lifting frame is arc-shaped, and the lifting frame is equipped with three evenly distributed stress-relieving rollers, the three stress-relieving rollers can evenly distribute the force during the lifting process, ensuring that the lifting frame can quickly and smoothly lift the extrusion die head.

[0040] When it is necessary to disassemble the extrusion head, use a crane or other lifting equipment to hook the lifting ring 1, move the lifting frame under the extrusion head and place it over the extrusion head, then slowly raise the lifting frame until the unloading roller lightly touches the extrusion head. Next, loosen the screws on the extrusion head, and move the crane or other lifting equipment horizontally outward to move the extrusion head away from the extrusion head hole. Finally, slowly lower the crane or other lifting equipment to safely place the extrusion head on the ground, completing the disassembly operation.

[0041] In summary, using this lifting frame for extrusion head hoisting operations is convenient, stable, and fast, effectively reducing the time required for extrusion head installation, disassembly, and maintenance, lowering production costs, and improving the company's economic benefits.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
