Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting equipment, and particularly relates to a vacuum sucker type hoisting equipment. Background Technique

[0002] During the installation process of structures such as wind turbine blades and concrete tower barrels, in order to avoid structural damage caused by hard contact, pure mechanical hoisting equipment such as truck cranes is usually not used. In recent years, due to its excellent performance such as high reliability, soft contact, and low (no) damage, the vacuum sucker has become the mainstream application product for the installation of wind power equipment. The working principle of the vacuum sucker equipment is as follows: the sucker is in full contact with the surface of the workpiece to form a sealed cavity, that is, no point in the cavity is allowed to communicate directly with the outside; the vacuum pump works to create a certain negative pressure in the cavity, and the workpiece and the sucker are tightly attached under the action of the air pressure difference inside and outside the cavity, so that the external hoisting equipment can control the sucker to realize the transfer and installation of the workpiece, etc.

[0003] The concrete wind turbine tower barrel structure is generally formed by splicing several concrete segments into a ring and then accumulating layer by layer; the diameter of the tower barrel gradually decreases uniformly with the increase of height, and the whole is in the shape of a truncated cone; "∩"-shaped door openings will be set in several layers close to the ground of the tower barrel, and maintenance personnel can enter and exit through them.

[0004] The necessary conditions for the vacuum sucker to adsorb the tower barrel segment are: (1) the vacuum sucker must be compatible with different diameters of the tower barrel segment within a certain range; (2) a stable and reliable sealed cavity should be formed, that is, structures such as "∩"-shaped door openings must be avoided, and the working position of the sucker should not exceed the edge of the segment. Among them, the adaptability of the sucker to different diameters of the segment and avoiding the "∩"-shaped door opening are important problems that need to be solved urgently in the field of wind turbine tower barrel installation by the vacuum sucker equipment. The single set of suckers on the current market cannot take into account the above conditions, so only by replacing the sucker can the hoisting of different types of segments be realized, which has a great impact on human resources, material resources and work efficiency. For this reason, a vacuum sucker type hoisting equipment is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a vacuum sucker type hoisting equipment, aiming to solve the problems put forward in the above background technique.

[0006] An embodiment of the utility model is realized as follows: a vacuum sucker type hoisting equipment includes a plurality of vacuum suckers, the vacuum suckers have a certain arc, the vacuum suckers are used for adsorbing the concrete segments of the wind turbine tower barrel, and further includes a hoisting cross beam and a mounting seat. The vacuum suckers are connected to the mounting seat, and the mounting seat is slidably arranged on the hoisting cross beam; the two mounting seats adjust the working center distance of the vacuum suckers on both sides by sliding relative to the hoisting cross beam.

[0007] Further, a limiting member and several groups of rollers are provided on each of the mounting seats, and the rollers are in contact with the circumferential side of the hoisting cross beam.

[0008] Further, limiting holes are formed in the hoisting cross beam.

[0009] Further, the number of the limiting holes is the same as that of the limiting members.

[0010] Further, a sealing strip is mounted on the surface of the vacuum suction cup.

[0011] Further, a balance beam is provided between the vacuum suction cup and the mounting seat. The vacuum suction cup is connected to the balance beam through a pin shaft, and the balance beam is connected to the mounting seat through a pin shaft.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The vacuum suction cup type hoisting device can adjust the working center distance between the two vacuum suction cups, and the vacuum suction cup can be compatible with the segment diameters within a certain range, effectively solving the problem that the mainstream products in the current market can only replace the suction cups when hoisting segments with different diameters and different structures, realizing multiple functions with one suction cup, greatly improving the working efficiency while saving costs.

[0018] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.

[0019] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0020] Such as Figures 1-3As shown in the figure, a vacuum suction cup type lifting device provided by an embodiment of the present invention includes:

[0021] A number of vacuum suction cups 2 with a certain arc, on the surface of which a special sealing strip is installed, and a stable and reliable sealed cavity can be formed when contacting the workpiece; the vacuum suction cups 2 are used to adsorb the concrete segments 1 of the wind power tower barrel, and the diameters at both ends of the concrete segments 1 of the wind power tower barrel will vary uniformly within a certain range, and some segments will have a "∩" - shaped door opening at the Figure 1 dotted line frame.

[0022] A crossbeam 3, and the vacuum suction cups 2 are connected to the crossbeam 3 through a pin shaft.

[0023] A lifting crossbeam 4, and the lifting crossbeam 4 serves as a sliding suction cup support member.

[0024] A mounting seat 5, the crossbeam 3 is connected to the mounting seat 5 through a pin shaft, and the mounting seat 5 is slidably arranged on the lifting crossbeam 4; the mounting seat 5 is a sliding suction cup mounting member, and it can slide left and right within a certain range on the lifting crossbeam 4 to adjust the working center distance of the lower - side two vacuum suction cups 2.

[0025] In the embodiment of the present invention, the vacuum suction cups 2 adopt a number of small - area suction cups with arcs instead of a whole large - area suction cup, which can ensure the adsorption safety. The vacuum suction cups 2, the crossbeam 3 and the mounting seat 5 are connected by means of pin shafts, making the overall structure relatively flexible. The mounting seat 5 adjusts the working center distance of the lower - side two suction cups by sliding left and right to a specified position on the lifting crossbeam 4, which can match different segment sizes and can effectively avoid the "∩" - shaped door opening. On the premise of ensuring adsorption safety, this device meets the requirements of hoisting segments with different sizes and different structures (with or without door openings) by the same device. As Figure 3 shown in (a) of the figure, it is a schematic diagram of the device hoisting a small - diameter segment; as Figure 3 shown in (b) of the figure, it is a schematic diagram of the device hoisting a large - diameter segment.

[0026] As Figures 1-3 shown, as a preferred embodiment of the present invention, each mounting seat 5 is provided with a limiting member 5 - 2 and 8 sets of rollers 5 - 1, and the 8 sets of rollers are in contact with the peripheral side of the lifting crossbeam 4 (4 sets on the upper side, 2 sets on the lower side, and 1 set on each of the left and right sides) to ensure that the mounting seat 5 does not deviate during the sliding process. A limiting hole 4 - 1 is opened on the lifting crossbeam 4.

[0027] In the embodiment of the present utility model, when the mounting seat 5 drives the vacuum suction cup 2 to slide to the designated position, screw in the limiting member 5-2, and the end of the limiting member 5-2 can be inserted into the corresponding limiting hole 4-1 of the cross beam, so as to fix the mounting seat 5, complete the adjustment of the working center distance of the two-side vacuum suction cups 2, and the equipment can work normally in this state. This equipment can greatly increase the adaptability of the suction cup to segments with different diameters on the premise of ensuring adsorption safety, and avoid the problem of frequently replacing the suction cup due to diameter mismatch.

[0028] The working principle of the present utility model is as follows:

[0029] For this vacuum suction cup type hoisting equipment, according to the size of the segment to be hoisted, control the mounting seat 5 to slide within a certain range of the hoisting cross beam 4. When the mounting seat 5 drives the vacuum suction cup 2 to slide to the designated position, screw in the limiting member 5-2, and the end of the limiting member 5-2 can be inserted into the corresponding limiting hole 4-1 of the cross beam, so as to fix the mounting seat 5, complete the adjustment of the working center distance of the two-side vacuum suction cups 2, and the equipment can work normally in this state.

[0030] The above is only the preferred embodiment of the present utility model. It should be noted that for those skilled in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicability of the patent.
