Description

Technical Field

[0001] The utility model belongs to the field of construction equipment, and in particular relates to a clamping type hoisting device based on a double-beam crane. Background Art

[0002] Double-beam crane is an industrial equipment used for lifting and moving heavy objects. It usually consists of two parallel beams (i.e. double beams) supporting the lifting mechanism, and can move along the tracks set up in factories, warehouses or docks to complete the lifting and moving tasks of heavy objects.

[0003] With urban development and industrial restructuring, many old factories need to be updated and renovated to adapt to new industrial needs and urban planning. During the indoor renovation process, if large equipment is installed, such as tower cranes or truck cranes and other large lifting equipment, it is often affected by factors such as roof covering, height restrictions, and floor bearing capacity restrictions, resulting in the inability to put large lifting equipment into use. In addition, the crane beams in old factories are often difficult to undertake lifting tasks alone due to lack of maintenance and other issues. Therefore, it is urgent to develop a clamp-type lifting device based on a double-beam crane to solve the problem of difficult indoor lifting operations in old factories and improve indoor lifting efficiency.

[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed below. The technical features in each embodiment of the utility model can be combined accordingly without conflicting with each other.

[0026] In the description of the present utility model, it should be understood that the terms "first" and "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0027] The existing indoor crane beams in old factories are often in disrepair and lack maintenance, making it difficult to undertake lifting tasks alone. In order to solve the problem of difficult indoor lifting operations in old factories, this embodiment, as a preferred method in the specific implementation, provides a clamping lifting device based on a double-beam crane, specifically as follows Figure 1 and Figure 2 shown.

[0028] The clamp-type lifting device comprises an upper structure 1, a lower structure 2, a connecting structure 3, a fixing member 5, a connecting rope 7 and a lifting device 8. Figure 3 As shown, the upper structure 1 is erected on two parallel running beams 9 of the main structure of the building, and the setting direction of the upper structure 1 is perpendicular to the direction of the running beams 9. And the length of the upper structure 1 is greater than the distance between the two running beams 9. Figure 4 As shown, the lower structure 2 is connected to the upper structure 1 via the connecting structure 3 , and the lower structure 2 rests against the lower surfaces of the two traveling beams 9 .

[0029] It should be noted that in actual engineering use, square steel is recommended for the upper structure 1 and the lower structure 2. Compared with channel steel and I-beam, the cross section of square steel is a more regular square. Placing square steel on two parallel crane beams 9 can ensure that the force of the clamp-type lifting device is more uniform, thereby making the overall device more stable.

[0030] The upper steel used in the upper structure 1 and the lower steel used in the lower structure 2 need to be determined by calculation based on the hoisting weight and the size of the crane beam 9. In this embodiment, the upper steel and the lower steel are both Q235, where the cross-sectional size of the upper steel is 25×25 cm, and the cross-sectional size of the lower steel is 10×10 cm.

[0031] A plurality of through holes are provided at intervals on the upper steel and the lower steel. The connecting structure 3 passes through the through holes in the upper structure 1 and the lower structure 2, and both ends of the connecting structure 3 are connected and fixed to the upper structure 1 and the lower structure 2 by fixing members 5. A plurality of connecting structures 3 are provided, and all are located between the two traveling beams 9.

[0032] In this embodiment, the connection structure 3 adopts a screw rod, and both ends of the screw rod are tapped with external threads of a certain length for adjusting the fixed position. In this embodiment, the fixing member 5 adopts a nut, and the inner nut is provided with an internal thread matching the external thread on the screw rod. The size and number of the screw rods connected between the upper steel and the lower steel are determined according to the calculation of the lifting weight. In this embodiment, 4 screw rods are provided, and the diameter of the screw rods used is 25 mm. A pad 4 is also provided between the screw rod and the nut to play the role of buffering, filling gaps, dispersing pressure, reducing friction, etc.

[0033] like Figure 1 As shown, a second connecting rope 10 is provided at one end of the upper steel, and the lower end of the second connecting rope 10 is connected to the lifting device 8. A first connecting rope 7 is provided at the other end of the upper steel, and the lower end of the first connecting rope 7 is connected to the counterweight. During use, the weight of the counterweight and the lifting device 8 are ensured to be equal to maintain the balance of the clamp-type lifting device and avoid uneven force on the upper steel.

[0034] In this embodiment, the first connecting rope 7 and the second connecting rope 10 are both steel wire ropes, and the lifting device 8 can be a hand chain hoist. Figure 5 As shown, in order to prevent the first connecting rope 7 and the second connecting rope 10 at both ends of the upper steel from sliding outward and falling off, protruding structures 6 are welded at both ends of the upper steel to prevent the first connecting rope 7 and the second connecting rope 10 from falling off.

[0035] Before implementing the plan, the structural performance of the existing crane beam of the main building should be checked to ensure that its force performance meets the load requirements before it can be put into use. The clamp-type lifting device provided in this embodiment is composed of upper steel, lower steel, screw rods, and nuts. It can be installed on the existing crane beam of the main building, and then use a hand winch and counterweight to achieve indoor lifting operations in old factories.

[0036] The above embodiment is only a preferred solution of the utility model, but it is not intended to limit the utility model. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, all technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
