Description

Technical Field

[0001] This utility model relates to the field of wellhead hoisting technology, and in particular to an auxiliary device for wellhead hoisting operations. Background Technology

[0002] In municipal engineering, water conservancy projects, and other construction scenarios involving pipeline laying, culvert hoisting is a crucial step. Currently, existing manhole hoisting devices present numerous problems when hoisting culverts. One significant challenge is accurately aligning the hoisted culvert with the existing culvert already laid below within the manhole. Construction workers often expend considerable time and effort on adjustments, severely impacting construction efficiency.

[0003] While some wellhead hoisting devices are equipped with guides to assist in culvert alignment, these guides are mostly fixed. When the upper culvert comes into contact with the fixed guide during its descent, the lack of a buffer structure causes the guide to violently impact the top of the lower culvert. This violent impact not only damages the top of the lower culvert, compromising its structural integrity, but also severely compromises the seal at the connection between the two culverts, leading to leaks and other problems during later use, thus affecting the normal operation of the entire pipeline system.

[0004] More seriously, when the guide device collides violently with the top of the culvert below, it generates a significant impact force. This impact force may be transmitted to the expansion mechanism used to hoist the upper culvert, causing the expansion mechanism to loosen its support and fixation of the upper culvert, and may even cause the upper culvert to fall off the hoisting device, resulting in a serious safety accident that threatens the lives of construction workers and causes property damage to the project. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figure 1 This is the first embodiment of the present invention. This embodiment provides a wellhead hoisting operation auxiliary device. The wellhead hoisting operation auxiliary device includes a main component 100, including a base 101. A support rod 102 is fixed on the base 101. A tie rod 103 slides inside the support rod 102. A lifting ring is provided at the top of the tie rod 103 for connecting with hoisting equipment.

[0031] Adjustment assembly 200, disposed on base 101, includes adjustment member 201, including first spring 2011 fixed to the surface of base 101, first spring 2011 in a stretched state, first spring 2011 is fixed to a mating block 2012 at the other end, adjustment rod 2013 is fixed to one side of mating block 2012, two fixing blocks 2014 are hinged to the bottom of adjustment rod 2013, fixing blocks 2014 are fixed to the top of base 101, limit block 2015 is fixed to the top of base 101, limit block 2015 is located on one side of adjustment rod 2013, used to limit adjustment rod 2013.

[0032] There are eight adjusting components 201, which are evenly distributed in a circle on the top of the base 101. When the hoisting equipment hoists the culvert, the upper culvert can be lowered to the lower culvert. If the two culverts are not aligned, the adjusting rod 2013 will hit the inner top wall of the lower culvert. Since the adjusting rod 2013 is pulled by the first spring 2011, the adjusting rod 2013 has a strong restoring force. At this time, the adjusting rod 2013 pushes the inner top wall of the lower culvert in the opposite direction, causing the upper culvert to move towards the center of the lower culvert, so that the two culverts are aligned.

[0033] Because the adjusting rod 2013 and the fixed block 2014 are hinged and pulled by the first spring 2011, the adjusting rod 2013 is movable. When the upper culvert descends to the lower culvert, causing the adjusting rod 2013 to hit the inner top wall of the lower culvert, the adjusting rod 2013 will stretch the first spring 2011, thereby causing the adjusting rod 2013 to swing, thus reducing the impact force on the lower culvert and preventing damage caused by violent collision.

[0034] Example 2

[0035] Reference Figures 1-5This is the second embodiment of the present invention, based on the previous embodiment. Specifically, the adjusting component 200 further includes a lifting member 202 disposed on the surface of the support rod 102, including a lifting ring 2021 sliding on the surface of the support rod 102. A support seat 2022 is fixed on the surface of the lifting ring 2021. Two support seats 2022 are grouped together. A push rod 2023 is hinged inside the support seat 2022. The other end of the push rod 2023 is also hinged to a support seat 2022. The support seat 2022 is fixed to the surface of the adjusting rod 2013. When the adjusting rod 2013 hits the inside of the culvert, it will drive the push rod 2023 to move the lifting ring 2021 upward. When the adjusting rod 2013 returns to its original position, the push rod 2023 can drive the lifting ring 2021 downward.

[0036] Specifically, the adjustment assembly 200 also includes a limiting member 203 disposed within the support rod 102, including a fixing seat 2031 fixed to the inner wall of the support rod 102, a limiting tube 2032 fixed within the fixing seat 2031, the limiting tube 2032 sliding within the pull rod 103, and the limiting tube 2032 used to limit the pull rod 103. When the hoisting equipment pulls the pull rod 103 upward, the lower end of the pull rod 103 can move to the top of the limiting tube 2032, thereby limiting the lower end of the pull rod 103 and preventing the pull rod 103 from descending.

[0037] Specifically, the limiting component 203 also includes a lifting plate 2033 fixed inside the lifting ring 2021. A top rod 2034 is fixed on the surface of the lifting plate 2033. The top rod 2034 slides on the limiting tube 2032, and the end of the top rod 2034 is very close to the end of the limiting tube 2032. When the lifting ring 2021 moves upward, it can drive the lifting plate 2033 to move upward, thereby driving the top rod 2034 to move upward, so that the end of the top rod 2034 moves out of the limiting tube 2032. A through groove is opened on the surface of the support rod 102, so that the lifting plate 2033 can slide inside the support rod 102.

[0038] Specifically, the end of the limiting tube 2032 is provided with a separation groove 2032-1. There are multiple separation grooves 2032-1, which allows the end of the limiting tube 2032 to expand inward. The push rod 2034 slides inside the limiting tube 2032. When the push rod 2034 starts to move upward, it will cause the end of the limiting tube 2032 to expand, thereby limiting the pull rod 103 and preventing the pull rod 103 from moving downward.

[0039] When the adjusting rod 2013 is reset, it can drive the lifting ring 2021 to move downward, thereby causing the lifting ring 2021 to drive the top rod 2034 to move downward through the lifting plate 2033. At this time, the end of the top rod 2034 will retract into the limiting tube 2032, causing the originally expanded opening at the end of the limiting tube 2032 to begin to contract, so that the pull rod 103 can move downward again.

[0040] Example 3

[0041] Reference Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0042] Specifically, the main component 100 also includes an expansion member 104 disposed on the surface of the support rod 102, including a rotating seat 1041 fixed to the surface of the support rod 102. A first connecting rod 1042 is hinged inside the rotating seat 1041. A support column 1043 is fixed to the other end of the first connecting rod 1042. The end of the support column 1043 is provided with anti-slip features, so that the support column 1043 can better lift the culvert. Through the hinge between the first connecting rod 1042 and the rotating seat 1041, the first connecting rod 1042 can drive the support column 1043 to swing. When the first connecting rod 1042 begins to move upward, the three support columns 1043 can expand outward simultaneously, thereby squeezing the inner wall of the culvert and lifting the culvert.

[0043] Specifically, the expansion member 104 also includes a second connecting rod 1044 hinged to the end of the first connecting rod 1042, and a rotating seat 1041 hinged to the other end of the second connecting rod 1044. A lifting sleeve 1045 is fixed to one side of the rotating seat 1041, and a connecting block 1046 is fixed to the inner wall of the lifting sleeve 1045. A sliding groove 102-1 is opened on the surface of the support rod 102, and there are three connecting blocks 1046, which slide in the three sliding grooves 102-1 respectively, and the three connecting blocks 1046 are fixed to the surface of the pull rod 103. When the pull rod 103 moves upward, it can drive the lifting sleeve 1045 to move upward through the connecting block 1046, thereby causing the lifting sleeve 1045 to drive the second connecting rod 1044 to move upward. Since the first connecting rod 1042 and the second connecting rod 1044 are hinged, and the first connecting rod 1042 is fixedly connected to the support rod 102 through the rotating seat 1041, the hinge point of the first connecting rod 1042 and the second connecting rod 1044 expands outward, thereby driving the three support columns 1043 to expand outward simultaneously.

[0044] Specifically, the main component 100 also includes a reset component 105. A second spring 1051 is sleeved on the surface of the pull rod 103. The second spring 1051 is in a compressed state. A positioning ring 1052 is fixed to the end of the second spring 1051. The positioning ring 1052 is fixed to the inner wall of the support rod 102. When the second spring 1051 is in a compressed state, it plays a positioning role through the positioning ring 1052, so that the second spring 1051 can apply a pushing force to the pull rod 103. When the culvert is hoisted into place, the hoisting equipment places the culvert in place. At this time, the pull rod 103 can move downward through the reset elastic force of the second spring 1051, thereby driving the lifting sleeve 1045 to move downward through the connecting block 1046. This causes the three support columns 1043 to retract inward at the same time, thereby moving away from the inner wall of the culvert and releasing the hoisting of the culvert.

[0045] Specifically, a positioning column 106 is fixed to the surface of the support rod 102, and a positioning cage 107 is fixed to the surface of the positioning column 106. When this wellhead hoisting operation auxiliary device is placed inside the culvert, the positioning cage 107 enables the device to be quickly positioned at the center of the culvert, thus facilitating the hoisting of the culvert. At the same time, the positioning cage 107 can also protect the device and prevent the hoisting mechanism from being damaged.

[0046] When in use, after the wellhead hoisting auxiliary device is placed inside the culvert, the tie rod 103 is quickly pulled upward. Due to inertia, the auxiliary device will remain stationary. When the tie rod 103 moves upward, the lifting sleeve 1045 can be moved upward through the connecting block 1046. This causes the lifting sleeve 1045 to move the second connecting rod 1044 upward. Since the first connecting rod 1042 and the second connecting rod 1044 are hinged, and the first connecting rod 1042 is fixedly connected to the support rod 102 through the rotating seat 1041, the hinge point of the first connecting rod 1042 and the second connecting rod 1044 expands outward, thereby causing the three support columns 1043 to expand outward simultaneously and fix the culvert. At this time, the lower end of the tie rod 103 is located at the upper end of the limiting tube 2032.

[0047] As the hoisting mechanism lowers the culvert, if the two culverts are not aligned, the adjusting rod 2013 will hit the inner top wall of the lower culvert. At this time, the adjusting rod 2013 will cause the lifting ring 2021 to move upward through the push rod 2023. The lifting ring 2021 will drive the top rod 2034 to move upward through the lifting plate 2033. This will cause the end of the top rod 2034 to move out of the limiting tube 2032, which will cause the end of the limiting tube 2032 to expand. This will allow the end of the limiting tube 2032 to limit the tie rod 103, thus preventing the tie rod 103 from moving downward. This positions the tie rod 103 and prevents the support column 1043 and the culvert from becoming loose.

[0048] When the adjusting rod 2013 impacts the inner top wall of the lower culvert, the adjusting rod 2013 stretches the first spring 2011, causing the adjusting rod 2013 to swing, thereby reducing the impact force on the lower culvert and preventing damage from a violent collision. Because the adjusting rod 2013 is pulled by the first spring 2011, it has a strong restoring force. At this time, the adjusting rod 2013 pushes the inner top wall of the lower culvert in the opposite direction, causing the upper culvert to move towards the center of the lower culvert, thereby aligning the two culverts.

[0049] When the culvert is hoisted into place, the hoisting equipment places the culvert in position. At this time, the hoisting equipment causes the tie rod 103 to move downward. It can move downward through the restoring force of the second spring 1051, thereby causing the three support columns 1043 to retract inward at the same time, thus moving away from the inner wall of the culvert.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
