Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a vacuum suction cup device that can rotate at multiple angles. Background Technology

[0002] Currently, the general method for changing the attitude of tunnel segments is to first use a vacuum suction cup to pick up the segment and lift it into the air, then move the segment to the segment attitude changing equipment, and finally have the working equipment pick it up for use.

[0003] This technology has the following drawbacks:

[0004] 1. Vacuum suction cups are only used for adsorbing / releasing tube sheets; rotation requires separate equipment.

[0005] 2. Additional rotating equipment requires construction space and generates linkage errors.

[0006] 3. The segment transfer requires three hoisting operations, which are time-consuming and require manual coordination. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art, this application proposes a vacuum suction cup device that can rotate at multiple angles to solve the problems existing in the prior art.

[0011] Gear and rack transmission mechanism: including gear, rack and hydraulic cylinder, wherein the gear is fixed coaxially with the gear shaft, and the rack is connected to the piston rod of the hydraulic cylinder. The hydraulic cylinder drives the rack to move linearly, thereby driving the gear and gear shaft to rotate.

[0012] Angle control module: includes a sensor and a cylinder position sensing plate. The sensor is mounted on a sensor mounting bracket and its position can be adjusted up and down. The cylinder position sensing plate is fixed to a rack. When the rack moves into the sensor's sensing range, a trigger signal controls the hydraulic cylinder to stop moving.

[0013] Equipment frame: The top is equipped with a lifting hook interface for connecting external lifting tools, and the bottom is equipped with a vacuum suction cup assembly and a gear and rack transmission mechanism.

[0014] As a further technical solution of this utility model: the gear shaft is mounted on the equipment frame by bearings to achieve rotational support; the vacuum suction cup assembly is fixedly connected to the lower end of the gear shaft by a flange.

[0015] As a further technical solution of this utility model: the sensor fixing bracket is a strip groove structure, and the sensor is fixed in the strip groove by bolts. The position can be adjusted in the vertical direction to change the sensing trigger point and correspondingly control the rotation angle of the tube segment.

[0016] As a further technical solution of this utility model: the lifting interface of the hook is a single hook structure, which is compatible with the hooks of general lifting equipment, so as to realize the rapid lifting and positioning of the equipment.

[0017] As a further technical solution of this utility model: the stroke range of the hydraulic cylinder satisfies the requirement that the segment rotation angle is ≤185°, and the rotation angle accuracy is controlled within ±0.5°.

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Example 1, as Figure 1-6 As shown, a multi-angle rotatable vacuum suction cup device includes a vacuum suction cup 1, a gear 2, a gear shaft 3, a rack 4, a hydraulic cylinder 5, a sensor 6, a sensor fixing bracket 7, a device frame 8, a hook lifting interface 9, a cylinder position sensing plate 10, and a tube 11.

[0031] Vacuum suction cup assembly 1: used to adsorb the tube 11, fixedly connected to the gear shaft 3, and rotates synchronously with the gear shaft 3;

[0032] Gear and rack transmission mechanism: including gear 2, rack 4 and hydraulic cylinder 5, the gear 2 is fixed coaxially with gear shaft 3, and rack 4 is connected to piston rod of hydraulic cylinder 5. The hydraulic cylinder 5 drives rack 4 to move linearly, thereby driving gear 2 and gear shaft 3 to rotate.

[0033] Angle control module: includes sensor 6 and cylinder position sensing plate 10. The sensor 6 is mounted on sensor fixing bracket 7 and its position can be adjusted up and down. The cylinder position sensing plate 10 is fixed to rack 4. When rack 4 moves into the sensing range of sensor 6, a trigger signal controls hydraulic cylinder 5 to stop moving.

[0034] Equipment frame 8: The top is equipped with a lifting hook interface 9 for connecting external lifting tools, and the bottom is equipped with a vacuum suction cup assembly 1 and a gear and rack transmission mechanism.

[0035] The working principle is as follows:

[0036] First, the invention is connected to the 9-hook lifting interface using the customer's lifting equipment and lifted into the air. The 9-hook lifting interface only requires a single hook for lifting, which can meet the requirements of most lifting equipment. Then, the invention is lifted to the section of the tube that needs to be rotated. The tube 11 is then lifted into the air using a vacuum suction cup. The lifting height should be more than half the length of the tube to leave sufficient rotation space. Then, the 5 hydraulic cylinder drives the rack downward, and the 10 cylinder position sensor also moves downward with the 4 rack. During the downward movement of the 4 rack, the 2 and 3 gear shafts begin to rotate. The 3 gear shaft drives the 1 vacuum suction cup and the 12 tube to rotate together. When the 10 cylinder position sensor descends with the 4 rack to the position of the 6 sensor, the system receives a signal, the 5 hydraulic cylinder stops, and the 12 tube is rotated to the required position. Finally, it is taken away by other equipment for use in the work. The position of sensor 6 can slide up and down the mounting bracket of sensor 7. When sensor 6 moves upward, the rotation angle of the tube segment will decrease accordingly, and vice versa. The limit of the rotation angle depends on the stroke of the hydraulic cylinder. The larger the stroke, the larger the rotation range. Generally, we calculate that it can be rotated to ≤185 degrees.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment have been appropriately combined to form other embodiments that are easy for those skilled in the art to understand.
