Description

Technical Field

[0001] The invention relates to the field of surveying equipment, and in particular to a pod. Background Art

[0002] At present, in order to detect the conditions inside a pipeline or a deep well, a crawler may be used. An existing method for placing and recovering the crawler is to use a rope and a hook, align the hook with the hook on the crawler, and then place the crawler in the deep well; after using the crawler, that is, completing the inspection in the well, the crawler is lifted out. If the depth is deep and the rope is not rigid, it is often difficult to connect the hook on the rope with the hook on the crawler in the pipeline (well). Ordinary operators often spend a lot of time aligning the hook and confirming whether the hook on the hanging rope outside the well matches the hook on the crawler in the well. Therefore, in the prior art, the recovery of the crawler is relatively troublesome. Summary of the invention

[0033] Figure 1 This is a schematic diagram of the use of the pod 010 in an embodiment of the present invention; Figure 2 A schematic diagram of a pod 010 provided in a first embodiment of the present invention; Figure 3 This is a schematic diagram of the pod 010 provided in the first embodiment of the present invention when the suspension part 310 is opened. Figures 1 to 3 The present embodiment provides a pod 010 for loading a crawler 3, including a carrier 100 for supporting the crawler 3, a connecting portion 200 connected to the carrier 100, and a bracket 300 connected to the connecting portion 200. The bracket 300 and the carrier 100 are arranged at a relative interval to form a storage space for accommodating the crawler 3. The bracket 300 and the carrier 100 form an entrance 11 for the crawler 3 to enter and exit at one end away from the connecting portion 200. The bracket 300 is provided with a hanging portion 310 for connecting a suspension rope 1. When the pod 010 is hoisted by the hanging portion 310, the entrance 11 is higher than the connecting portion and faces upward. The pod 010 loaded with the crawler 3 can be lowered into a deep well or a pipeline along with the suspension rope 1. After the crawler 3 leaves the pod 010, relevant operations are performed. After the operation is completed, the crawler 3 is controlled to re-enter the nacelle 010 and then pulled up by the suspension rope 1, thereby completing the recovery of the crawler 3.

[0034] Figure 2 In the embodiment of the present invention, the carrier 100 is roughly rectangular, and a guide block 110 is convexly provided on the carrier 100 to guide the crawler 3 when entering the accommodation space, and the tires on both sides of the crawler 3 are respectively located on both sides of the guide block 110. In this way, the crawler 3 is not easy to deviate from the center of the accommodation space. In order to enable the crawler 3 to smoothly enter and exit the accommodation space, the end of the carrier 100 away from the connecting portion 200 has a guide slope 120. The guide slope 120 allows the wheels of the crawler 3 to more easily drive onto the carrier 100, and also reduces the impact of landing when the crawler 3 drives off the carrier 100.

[0035] like Figure 2 As shown, optionally, a toothed anti-skid structure 130 is provided at the bottom of the supporting platform 100 to enhance the grip of the pod 010 after it falls into the deep well.

[0036] The connecting part 200 includes two semicircular arc-shaped tubes, one end of which is used to connect the bracket 300. A wire hole 220 is formed between the two tubes, and the cable 2 of the crawler 3 passes through the wire hole 220. In this way, when the crawler 3 is in motion, the cable 2 will not swing arbitrarily and collide with the well wall or pipe wall, thereby protecting the cable 2.

[0037] Two tire stops 210 are arranged inside the connection part 200. When the crawler 3 enters the accommodation space, the tire stops 210 can abut against the tires of the crawler 3 after the crawler 3 is in place. In order to reduce the impact force, the tire stops 210 can be provided with elastic buffer material, such as rubber.

[0038] The bracket 300 includes two cross bars, one end of which is connected to the tube body of the connecting part 200, and the other end extends to the entrance 11. The hanging part 310 is arranged at one end of the bracket 300 away from the connecting part 200, and is hinged to the bracket 300. In this embodiment, the hanging part 310 is a U-shaped tube. When the hanging part 310 is lifted by the hanging rope 1, it can rotate relative to the bracket 300. When the pod 010 is lifted by the hanging part 310, the entrance 11 faces upward or tilts upward to prevent the crawler 3 from falling out of the entrance 11.

[0039] Figures 1 to 3 When the pod 010 in the embodiment is in use, the crawler 3 is first placed in the pod 010, and the cable 2 passes through the wire hole 220. The sling 1 is tied to the hanging part 310, and then the pod 010 and the crawler 3 are lowered to the bottom of the well together by the sling 1. After the pod 010 lands, the crawler 3 drives out of the pod 010 from the entrance 11, and the cable 2 remains in the state of passing through the wire hole 220. When the crawler 3 completes the operation, it drives into the pod 010. The tire abuts against the tire stopper 210 and moves into place. At this time, the pod 010 and the crawler 3 are lifted from the deep well by the sling 1 to complete the recovery of the crawler 3.

[0040] Figure 4 1 is a schematic diagram of a pod 010 from a first perspective in a second embodiment of the present invention; Figure 5 This is a second perspective diagram of the pod 010 in the second embodiment of the present invention. Figure 4 and Figure 5 , which is similar to the structure of the pod 010 of the previous embodiment, differs in the structure of the card frame 300 and the connection method between the card frame 300 and the connecting part 200.

[0041] exist Figure 4 In the embodiment, the card holder 300 is rotatably connected to the connecting portion 200 , and the pod 010 further includes an electric control mechanism for controlling the rotational position of the card holder 300 relative to the supporting platform 100 to adjust the size of the entrance 11 .

[0042] Specifically, the electric control mechanism includes a one-way bearing 250 and an electric locking device 240 that cooperates with the one-way bearing 250. The bracket 300 is rotatably connected to the connecting part 200 through the one-way bearing 250. When the electric locking device 240 is not powered on, the locking pin of the electric locking device 240 can enable the bracket 300 to rotate only in the direction close to the supporting platform 100 to reduce the accommodating space and fix the crawler in the pod 010; when the electric locking device 240 is powered on, the bracket 300 can rotate in the direction away from the supporting platform 100 to expand the accommodating space so that the crawler can drive out of the pod 010.

[0043] In this embodiment, the hanging part 310 is fixedly connected to one end of the bracket 300 away from the connecting part 200. When the hanging rope 1 is pulled up to lift the entire pod 010 through the hanging part 310, the entrance 11 of the pod 010 is higher than the connecting part 200 and faces upward to prevent the crawler from falling out of the entrance 11.

[0044] In an optional embodiment, a limiting portion 320 is provided on the bracket 300 to limit the movement of the crawler in the accommodating space.

[0045] In this embodiment, a rotatable guide wheel 230 is also provided on the connecting portion 200. After the cable 2 passes through the tail of the pod 010, it will stick to the guide wheel 230. When the cable 2 is pulled, the guide wheel 230 plays a role in guiding and protecting the cable 2.

[0046] like Figure 4 As shown, the guide block 110 in this embodiment can be divided into a strip-shaped left guide block 110 and a strip-shaped right guide block 110 to respectively limit the left wheel and the right wheel of the crawler. In this embodiment, the connecting portion 200 can be connected to the bracket 300 through a one-way bearing 250 and another coaxially arranged ordinary bearing to enhance stability. Of course, the two coaxially arranged bearings can also be one-way bearings 250.

[0047] Figure 4 When the pod 010 of the embodiment is used, the crawler is first driven into the pod 010, and the bracket 300 is rotated to lower the bracket 300, so that the crawler is firmly locked in its proper position. Then the hanging rope 1 outside the well is connected to the hanging part 310 on the bracket 300, and the pod 010 is slowly lowered into the deep well. When reaching the well, the locking pin of the electric locking device 240 is disengaged, so that the bracket 300 can be moved along the well. Figure 5Turn counterclockwise, tighten the hanging rope, and rotate the bracket 300 to open. At this time, the crawler can be directly driven to detach from the pod 010 and perform normal inspection work. After the crawler completes the in-well inspection task, it will be automatically poured into the pod 010, and then the hanging rope 1 will be lowered. The bracket 300 will be lowered due to gravity and automatically clamp the crawler. Finally, the pod 010 is lifted up by the hanging rope 1, and the crawler is recovered. Through this embodiment, the pipeline robot can be placed in the pod 010 for lifting up and down; through electric control, the opening and closing of the pod 010 can be made intelligent and automated.

[0048] In summary, a pod according to an embodiment of the present invention includes a bearing platform for supporting a crawler, a connecting portion connected to the bearing platform, and a bracket connected to the connecting portion. The bracket and the bearing platform are arranged at a relative interval to form a storage space for accommodating the crawler. The bracket and the bearing platform form an entrance and exit for the crawler to enter and exit at an end away from the connecting portion. The bracket is provided with a hanging portion for connecting a lifting rope. When the pod is lifted by the hanging portion, the entrance and exit is higher than the connecting portion. In this way, the pod can be used to put the crawler into a deep well or a pipeline, and then the crawler can be driven out of the pod to operate. After the operation is completed, return to the pod, and then recover the crawler and the pod together. In the process of recovering the crawler, the operation of hook alignment is avoided, so the recovery is relatively simple and efficient.

[0049] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
