Description

Technical Field

[0001] The utility model belongs to the field of underwater detection equipment for urban pipe networks, and specifically relates to a lifting buffer locking device and a pipeline detection machine and equipment. Background Art

[0002] The pipeline inspection robot is a special robot developed for maintenance and repair operations such as inspection, spraying, interface welding, and foreign matter cleaning of oil, gas, liquid and other pipelines. It can enter complex and changeable non-structural pipeline environments that are beyond the reach of humans. Through the non-destructive testing devices and operating devices it carries, it can perform online inspection, cleaning, and maintenance of working pipelines to ensure the safety of the pipelines and unimpeded operation.

[0003] However, when lifting a pipeline inspection robot in a fully loaded working state, there was no buffer device in the past, and the cable end of the pipeline inspection robot was easy to touch the pipeline limit. After touching the pipeline limit, due to the large weight of the pipeline inspection robot in a fully loaded state and the large inertia of the lifting process itself, the impact force will be transmitted to the pipeline inspection robot or the lifting equipment. The inertia of the pipeline robot will damage the limiter, or the cable reel will not stop in time, causing the cable to break. Utility Model Content

[0042] The following is an explanation of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0043] It should be noted that, in the present utility model, the up, down, left and right in the figure are deemed to be the up, down, left and right of the lifting buffer locking device and the pipeline detection machine equipment described in this specification.

[0044] The exemplary embodiments of the present invention are now introduced with reference to the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to disclose the present invention in detail and completely and to fully convey the scope of the present invention to those skilled in the art. The terms in the exemplary embodiments shown in the accompanying drawings are not intended to limit the present invention. In the accompanying drawings, the same units / elements are marked with the same reference numerals.

[0045] Unless otherwise specified, the terms (including technical terms) used herein have the commonly understood meanings to those skilled in the art. In addition, it is understood that the terms defined in commonly used dictionaries should be understood to have the same meanings as those in the context of the relevant fields, and should not be understood as idealized or overly formal meanings.

[0046] This embodiment relates to a lifting buffer locking device, which is suitable for lifting a pipeline inspection robot. Figure 1 The lifting buffer locking device includes a pulling mechanism 20 and a buffer platform 30. The pulling mechanism 20 is installed on the pulling mechanism 20. The specific structure thereof is described in detail below.

[0047] The pulling mechanism 20 at least has a wire pulley 21 suitable for winding and guiding the cable 40. The function of the pulling mechanism 20 is to transport the cable 40, change the direction of the cable 40, guide the cable 40 to walk along a preset direction, and finally the cable 40 passes through the buffer platform 30 downward.

[0048] Specifically, the buffer platform 30 is suitable for installing the pulling mechanism 20, and the cable 40 passes through the center of the buffer platform 30. A plurality of buffer cylinders 33 are arranged around the cable 40 to transfer the impact force exerted on the cable 40, and a plurality of locking cylinders 34 are also arranged to lock or release the cable 40.

[0049] The cable 40 passes through the guide wheel 21 and then passes through the buffer platform 30 to be connected to the pipeline inspection robot. Therefore, when the cable end on the pipeline inspection robot side touches the limit position, the buffer cylinder 33 can effectively transfer the impact force to the buffer cylinder 33 for buffering, thereby avoiding structural damage to the lifting equipment and the robot, or cable breakage due to sudden stop of the robot.

[0050] After the buffer is reset, the locking cylinder 34 can clamp and fix the cable end.

[0051] Reference Figure 2 The buffer platform 30 includes an upper buffer platform 31 and a lower buffer platform 32 which are arranged opposite to each other up and down.

[0052] A plurality of buffer cylinders 33 are mounted on the upper buffer platform 31, and the piston rod of each buffer cylinder 33 passes through the upper buffer platform 31, and a universal joint 311 is mounted on the rod head of the piston rod. That is, the cylinder body of the buffer cylinder 33 is mounted on the upper buffer platform 31, and the axial center line of the buffer cylinder 33 is perpendicular to the upper buffer platform 31.

[0053] In some embodiments, the upper buffer platform 31 presents Figure 1 The disc is in the shape of a disk, and a circular hole for the cable 40 to pass through is opened in the center of the disc.

[0054] In some embodiments, the number of buffer cylinders 33 is 4 and they are evenly spaced apart.

[0055] A plurality of locking cylinders 34 are mounted on the lower buffer platform 32, and the push rod head of each locking cylinder 34 faces the cable 40 to clamp or release the cable 40. That is, when the push rod of the locking cylinder 34 is extended, the cable 40 can be clamped; when the push rod of the locking cylinder 34 is retracted, the cable 40 can be released.

[0056] In some embodiments, the number of locking cylinders 34 is two and they are distributed at 180 degrees.

[0057] The universal joint 311 is installed on the lower buffer platform 32, and the process of the buffer cylinder 33 transferring the impact force is as follows:

[0058] When the cable end on the pipeline inspection robot side touches the limit point, the cable 40 transmits the impact force to the lower buffer platform 32, the lower buffer platform 32 swings around the universal joint 311, and the buffer cylinder 33 connected to the universal joint 311 expands and contracts to transfer the impact force, thereby avoiding the impact force from causing structural damage to the lifting equipment and the robot.

[0059] like Figure 1 and Figure 3 As shown, the lower buffer platform 32 is a circular ring plate structure, the cable 40 passes through the center hole of the circular ring plate, and the cylinder body of the locking cylinder 34 is installed at the circular ring of the circular ring plate.

[0060] See also Figure 2 The cable 40 is inserted through the limit seat 50, and the limit seat 50 is placed in the center hole of the lower buffer platform 32. The push rod of the locking cylinder 34 clamps the cable 40 by clamping the limit seat 50. Specifically, the limit seat 50 includes:

[0061] The outer limiting cylinder 51 and the inner limiting cylinder 52 are coaxially sleeved.

[0062] See also Figure 4The cable 40 passes through the inner stopper 52 and is close to the inner wall, and part of the outer wall of the inner stopper 52 first extends radially and then extends axially to form a hook lock. In some embodiments, the upper outer wall of the inner stopper 52 forms a hook lock.

[0063] It is worth mentioning that although the inner limiting tube 52 is placed inside the outer limiting tube 51, the length of the inner limiting tube 52 is greater than that of the outer limiting tube 51. Figure 4 As shown, the bottom end of the inner limiting tube 52 extends along the cable 40 to the outside of the outer limiting tube 51 , and its function is to extend the protection of the cable 40 .

[0064] The limit seat 50 also includes a connecting plate 53, the push rod head of the locking cylinder 34 is fastened to one side of the connecting plate 53, and the other side of the connecting plate 53 is inserted into the outer limit tube 51, and the plate wall on the inserted side first extends horizontally and then extends vertically to form a hook tongue to cooperate with the hook lock to lock or release the cable 40.

[0065] It should be noted that, in another embodiment, two ribs are also fixed to the lower buffer platform 32 , and the two ribs are distributed on the lower buffer platform 32 at an angle of 180 degrees, and the ends of the two ribs are connected and clamped to the outer limiting cylinder 51 of the limiting seat 50 .

[0066] The arrangement of the two ribs and the two locking cylinders 34 is shown in Figure 5 .

[0067] About the working process of locking cylinder 34:

[0068] When the cable end on the pipeline inspection robot side touches the limit position, the cable 40 transmits the impact force to the lower buffer platform 32 through the limit seat 50 and the rib plate, and the lower buffer platform 32 swings around the universal joint 311, and the buffer cylinder 33 connected to the universal joint 311 expands and contracts to transfer the impact force. As the impact force is gradually dissipated, the cable 40 is gradually reset. At this time, the push rod of the locking cylinder 34 extends / retracts, and the push rod drives the connecting plate 53. The hook tongue on the connecting plate 53 gradually cooperates with the hook lock in the limit seat 50. The hook tongue and the hook lock can clamp or release the cable 40 after being locked or released.

[0069] Please continue reading Figure 2 , the driving mechanism 20 comprises:

[0070] (1) The first bracket 22 has a bottom end fixed to the buffer platform 30 and a top end formed with a vertical fixing claw 221 .

[0073] (2) Fix the hydraulic cylinder 23.

[0074] The cylinder body of the fixed hydraulic cylinder 23 is installed on the buffer platform 30, specifically on the upper buffer platform 31. A horizontal fixing claw 231 is installed on the top of the hydraulic push rod. The horizontal fixing claw 231 is located between the two vertical fixing claws 221 to form a three-claw hook to ensure that the lifting buffer locking device can be firmly hung on the door-type bracket 10.

[0075] The extension and retraction of the fixing hydraulic cylinder 23 can control the clamping and releasing of the horizontal fixing claws 231 .

[0076] (3) Fixed seat 24.

[0077] The guide wheel 21 is mounted on a fixing seat 24 , and the fixing seat 24 is mounted on the first bracket 22 .

[0078] Specifically, the first bracket 22 also includes a lower horizontal rod, which is located between the two vertical arms and is installed on the upper buffer platform 31, and an upper horizontal rod is also installed between the top ends of the two vertical arms. The fixed seat 24 is installed between the upper horizontal rod and the lower horizontal rod, and the wire wheel 21 is arranged on the fixed seat 24, and the wire wheel 21 can rotate around the fixed seat 24.

[0079] In some embodiments, the wire wheel 21 is mounted on the fixing seat 24 via a clamping plate, and the clamping plate is detachable, thereby facilitating the replacement of the wire wheel 21, thereby adapting to cables of various specifications.
