Description

Technical Field

[0001] This invention relates to the field of oil and gas exploration, and more specifically to a hook for securing climbing ladders. Background Technology

[0002] At well logging sites, target flow sensors are typically installed inside overhead troughs. These troughs are usually located at heights ranging from 3 to 7 meters above the ground. Therefore, installing target flow sensors at this height requires leaning a ladder against the side wall of the overhead trough, and then standing on the ladder to complete the installation.

[0003] However, since the overhead trough is a sloping hollow pipe with a smooth surface, using only a climbing ladder cannot effectively solve the installation problem of the target flow sensor, and there are even safety hazards during the climbing process.

[0004] Therefore, it is desirable to provide a device that can solve the above problems and effectively avoid safety hazards during climbing. Summary of the Invention

[0005] The purpose of this invention is to provide a secure hook for fixing climbing ladders. This device forms an initial fixation by engaging the hook claw with the support object, and then connects a polygonal or round pipe clamp to the climbing ladder for secondary fixation. The combination of the two fixing structures effectively reinforces the climbing ladder, thereby effectively avoiding safety hazards during climbing.

[0006] According to the present invention, a fastening hook for securing a climbing ladder is provided, comprising a support rod, a polygonal tube clamp mounted on the support rod, a round tube clamp spaced apart from the polygonal tube clamp and mounted on the support rod, and a top inner threaded tube fixedly connected to the top end of the support rod, wherein the end of the top inner threaded tube away from the support rod is connected to a claw for securing an external support, wherein the polygonal tube clamp is configured to secure a square support provided on the climbing ladder, and the round tube clamp is configured to secure an arc-shaped support provided on the climbing ladder.

[0007] In one embodiment, the support rod includes a first pipe clamp wire tube and a second pipe clamp wire tube that are fixedly connected to one side of the support rod in sequence, wherein the first pipe clamp wire tube is used to connect to the polygonal pipe clamp, and the second pipe clamp wire tube is used to connect to the round pipe clamp.

[0008] In one embodiment, a first rubber sleeve for clamping the square support is installed on the inner surface of the polygonal tube clamp, and an opening is provided on one side of the first rubber sleeve.

[0009] In one embodiment, the polygonal pipe clamp includes a first connecting portion and a second connecting portion, wherein the first connecting portion includes a locking mechanism for fixing the square support, and the second connecting portion includes a first support rod fixedly connected to the second connecting portion, the first support rod being fixedly connected to the first pipe clamp wire tube via a first inner wire tube.

[0010] In one embodiment, the round pipe clamp includes a connecting buckle disposed at the top of the round pipe clamp to limit the opening and closing trajectory of the round pipe clamp, and a locking buckle disposed at the bottom of the round pipe clamp to control the opening and closing of the round pipe clamp.

[0011] In one embodiment, a second rubber sleeve for clamping the arc-shaped support is installed on the inner surface of the round tube clamp.

[0012] In one embodiment, a second support rod is connected to the side of the round tube clamp near the support rod, and the second support rod is fixedly connected to the second tube clamp wire tube through a second inner wire tube.

[0013] In one embodiment, the hook is configured as a semi-circular arc structure for fixed connection with an external support.

[0014] In one embodiment, a back cap for adjusting the angle of the hook is provided between the hook and the top inner wire tube.

[0015] In one embodiment, the support rod includes a sleeve disposed between the first clamp wire tube and the second clamp wire tube and sleeved on the support rod, and the outer surface of the sleeve is provided with a plurality of threading holes. Attached Figure Description

[0016] The invention will now be described in detail with reference to the accompanying drawings, in which:

[0017] Figure 1 The schematic diagram shows a structural schematic of a hook for securing a climbing ladder according to the present invention.

[0018] In the accompanying drawings, the same parts use the same reference numerals. The drawings are not drawn to scale. Detailed Implementation

[0019] The invention will now be further described with reference to the accompanying drawings.

[0020] Figure 1 A schematic diagram illustrates the structure of a securing hook for fixing a climbing ladder according to the present invention. Figure 1As shown, the fixing hook 100 for securing a climbing ladder according to the present invention mainly includes a support rod 10, a polygonal tube clamp 20 mounted on the support rod 10, a round tube clamp 30 spaced apart from the polygonal tube clamp 20 and mounted on the support rod 10, and a hook claw 40 for securing an external support. The hook claw 40 is fixedly connected to the top of the support rod 10 via a top inner threaded tube 41.

[0021] The support rod 10 is constructed as a steel rod with threads on its outer surface, and includes an upper part 1, a middle part 2, and a lower part 3. The upper part 1 of the support rod 10 is threadedly connected to a top internal threaded tube 41. The top internal threaded tube 41 is also threadedly connected to a hook 40. Thus, the top internal threaded tube 41 acts as a connector, securely fixing the upper part 1 of the support rod 10 and the hook 40 together. One side of the middle part 2 of the support rod 10 is fixedly connected to a first pipe clamp threaded tube 11, which is used to fix a polygonal pipe clamp 20. One side of the lower part 3 of the support rod 10 is fixedly connected to a second pipe clamp threaded tube 12, which is used to fix a round pipe clamp 30.

[0022] like Figure 1 As shown, the hook 40 is constructed in a semi-circular arc shape and includes a curved portion 401 and an upright portion 402. The curved portion 401 is arc-shaped; however, it is understood that the curved portion 401 can also be constructed in other shapes, such as a semi-circle. Furthermore, during the fixing of the climbing ladder, the curved portion 401 is fixed to an external support, thereby effectively limiting the movement range of the climbing ladder. The bottom end of the upright portion 402 is threaded and threadedly connected to one end of the top inner threaded tube 41. The top 1 of the support rod 10 has a threaded structure and is threadedly connected to the other end of the top inner threaded tube 41. Specifically, the bottom of the upright portion 402 and the upper part 1 of the support rod 10 are both screwed into the top inner threaded tube 41.

[0023] The round tube clamp 30 can be fixedly connected to the arc-shaped support set on the climbing ladder. It should be noted that the above-mentioned "arc-shaped support" includes bamboo tubes with arc-shaped or similar surface shapes.

[0024] In one specific embodiment of the present invention, such as Figure 1 As shown, the round tube clamp 30 includes a connecting buckle 31 at its top, which restricts the opening and closing trajectory of the round tube clamp 30, and a locking buckle 32 at its bottom, which controls the opening and closing of the round tube clamp 30. The combined use of the round tube clamp 20 and the hook 40 effectively reinforces the climbing ladder with the curved surface of the bamboo tube.

[0025] In one embodiment of the present invention, such as Figure 1As shown, a second rubber sleeve 33 for clamping the arc-shaped support is installed on the inner surface of the round tube clamp 30. The second rubber sleeve 33 is configured as two sets of rubber sleeves of equal length, with a length approximately three-fifths of the semicircle. Furthermore, gaps are left at the joints of both sets of rubber sleeves. This allows the two sets of rubber sleeves to effectively stretch when reinforcing the arc-shaped bamboo-joint tube, thereby filling the gaps at the joints and enhancing the reinforcing effect of the round tube clamp 20 on the arc-shaped bamboo-joint tube.

[0026] In one embodiment of the present invention, such as Figure 1 As shown, one sidewall of the round tube clamp 30 (e.g.) Figure 1 A second support rod 34 is fixedly connected to the left side wall 36. The outer surface of the second support rod 34 is threaded, forming a threaded connection with one end of the second inner threaded tube 35. The outer surface of the second pipe clamp wire tube 12, which is provided on the support rod 10, is threaded, forming a threaded connection with the other end of the second inner threaded tube 35. Specifically, both the second pipe clamp wire tube 12 and the second support rod 34 are screwed into the second inner threaded tube 35.

[0027] The polygonal tube clamp 20 can be securely connected to a square support installed on the climbing ladder. It should be noted that the aforementioned "square support" encompasses bamboo-like tubes with flat or similar shaped surfaces. Furthermore, the polygonal tube clamp 20 includes a clamp positioned on one side (e.g., Figure 1 The first connecting portion 22 on the right side of the polygonal tube clamp 20, and the portion provided on the other side (e.g., the first connecting portion 22 on the right side of the polygonal tube clamp 20). Figure 1 The second connecting part 23 is located on the left side of the polygonal tube clamp 20. The first connecting part 22 is equipped with a locking mechanism 221 for securing the bamboo-joint tube with a flat surface. The second connecting part 23 is fixedly connected to the first support rod 231. The combined use of the polygonal tube clamp 20 and the hook 40 effectively reinforces the climbing ladder with the bamboo-joint tube having a flat surface.

[0028] In one embodiment of the present invention, such as Figure 1 As shown, the outer surface of the first support rod 231 is threaded, forming a threaded connection with one end of the first inner threaded tube 24. The outer surface of the first tube clamp 11, which is mounted on the support rod 10, is threaded, forming a threaded connection with the other end of the first inner threaded tube 24. Specifically, both the first tube clamp 11 and the first support rod 231 are screwed into the first inner threaded tube 24.

[0029] In one embodiment of the present invention, such as Figure 1As shown, a first rubber sleeve 21 for clamping a bamboo-joint tube with a flat surface is installed on the inner surface of the polygonal tube clamp 20. The first rubber sleeve 21 is arranged around the four sides of the inner surface of the polygonal tube clamp 20. Moreover, an opening 211 is provided on the side of the first rubber sleeve 21 near the first connecting part 22, so that when reinforcing the bamboo-joint tube with a flat surface, the first rubber sleeve 21 can be effectively stretched and the opening 211 of the first rubber sleeve 21 can be filled, thereby enhancing the reinforcing effect of the polygonal tube clamp 20 on the bamboo-joint tube with a flat surface.

[0030] In one embodiment of the present invention, such as Figure 1 As shown, back caps of the same material are provided between the inner threaded tube 41 and the hook 40, between the first inner threaded tube 24 and the polygonal tube clamp 20, and between the second inner threaded tube 35 and the round tube clamp 30, respectively, to adjust the corresponding positions of the hook 40, the polygonal tube clamp 20, and the round tube clamp 30. In a specific embodiment of the present invention, the back cap is constructed as a prismatic back cap. However, it is understood that the back cap can also be formed into other shapes, such as hexagonal prisms.

[0031] In one embodiment of the present invention, such as Figure 1 As shown, a sleeve 13 is provided between the middle part 2 and the lower part 3 of the support rod 10. Moreover, the sleeve 13 is fitted onto the support rod 10 to separate the first wire clamp tube 11 from the second wire clamp tube 12.

[0032] like Figure 1 As shown, a plurality of threading holes 131 are provided on the outer surface of the sleeve 13. In an embodiment of the present invention (not shown), the threading holes 131 can be used to install polygonal pipe clamps 20. By fixing the polygonal pipe clamps 20 to the bamboo joint tubes with flat surfaces on the climbing ladder, the climbing ladder with curved surface bamboo joint tubes can be reinforced at different angles, thereby effectively avoiding safety hazards that may occur during climbing.

[0033] In one embodiment of the present invention (not shown), the threaded hole 131 can be used to install the round tube clamp 30. The round tube clamp 30 is fixedly connected to the bamboo joint tube with the arc-shaped surface on the climbing ladder, thereby achieving reinforcement of the climbing ladder with the flat surface bamboo joint tube at different angles, and thus effectively avoiding safety hazards that may occur during climbing.

[0034] The following is a brief description of the installation steps for the hook 100 used to secure the climbing ladder.

[0035] First, the support rod 10 and the hook 40 are fixedly connected through the top inner thread tube 41. Specifically, the upright part 402 and the upper part 1 of the support rod 10 are screwed into the top inner thread tube 41.

[0036] Then, depending on the shape of the bamboo tube surface on the climbing ladder, choose to install a round tube clamp 30 on the support rod 10 alone, or install a polygonal tube clamp 20 alone, or install both polygonal tube clamp 20 and round tube clamp 30 at the same time.

[0037] Install the polygonal pipe clamp 20: The support rod 10 and the polygonal pipe clamp 20 are fixedly connected through the first internal threaded tube 24, specifically, the first pipe clamp threaded tube 11 and the first support threaded rod 231 are screwed into the first internal threaded tube 24.

[0038] Install the round pipe clamp 30: The support rod 10 and the round pipe clamp 30 are fixedly connected by the second internal threaded tube 35. Specifically, the second pipe clamp threaded tube 12 and the second support threaded rod 34 are screwed into the first internal threaded tube 24.

[0039] Next, select a suitable support and engage the curved part 401 of the hook 40 with the support to complete the first stage of fixing.

[0040] Then, the bamboo tubes on the climbing ladder are fixed by a combination of round tube clamp 30, polygonal tube clamp 20, or round tube clamp 30 and polygonal tube clamp 20, thus completing the second stage of fixing work.

[0041] Finally, if the climbing ladder is still not secure at this point, a suitable hole can be selected on the threaded hole 131 of the sleeve 13, and an additional round pipe clamp 30 or polygonal pipe clamp 20 can be fixedly connected to the hole to reinforce the climbing ladder at different angles, thus completing the third stage of fixation.

[0042] By using three different methods of fixation in three stages, the climbing ladder becomes more secure and reliable, thus effectively avoiding safety hazards during the climbing process.

[0043] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art can easily make changes or modifications within the scope of the present invention, and such changes or modifications should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
