Description

Technical Field

[0001] This utility model relates to the field of well shaft transportation technology, specifically to a well shaft transportation device. Background Technology

[0002] During the construction process, the precast well casing needs to be lifted and transported from the transport vehicle to the construction site by a crane. The traditional binding method takes an average of 15-20 minutes to fix one well casing and has a safety accident rate of about 5%.

[0003] However, existing technologies typically involve binding the well casing with steel wire ropes before hoisting and transporting it. The other end of the steel wire rope is then attached to the crane hook. After the prefabricated well casing is hoisted to the construction site by the crane using the steel wire rope, the steel wire rope needs to be removed from the outside of the well casing. The entire transportation process is complex and reduces the efficiency of hoisting and transporting the well casing. In addition, using steel wire ropes to bind and hoist the well casing makes it difficult to ensure that the well casing is in an upright position when it is installed at the construction site. The well casing needs to be manually adjusted in position when it is lowered, which increases the risk of hoisting and transporting it.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a well shaft transportation device to solve the problems mentioned in the background art, such as the low work efficiency of using steel wire ropes to tie and hoist the well shaft for transportation, the need for manual adjustment of the well shaft's posture during the lowering process, and the existence of certain safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Well shaft transport equipment, including:

[0008] The tightening unit includes an outer support assembly that is tightened against the inner wall of the well casing for tightening and limiting the well casing, and an inner support assembly located on the upper part of the outer support assembly for tensioning and adjusting the outer support assembly.

[0009] The lifting unit includes a lifting rod located between the inner support assembly and the outer support assembly, used to lift the well shaft component in a top-tightened and limited position. The inner support assembly is slidably located on the outside of the lifting rod.

[0010] Furthermore, the external support assembly includes:

[0011] A retaining ring is fixedly connected to the lower end of the lifting rod;

[0012] The convex plates are provided in at least three sets and are fixedly connected to the outside of the fixing ring at equal angles;

[0013] The second hinge shaft is fixedly inserted into the inside of the protrusion plate;

[0014] The outer support arm has one end hinged to the second hinge shaft and the other end pointing towards the inner wall of the well casing.

[0015] The clamping block is fixedly connected to one end of the outer support arm opposite the convex plate and is used to clamp the inner wall of the well casing.

[0016] Furthermore, a friction pad is fixedly connected to one end of the clamping block relative to the outer support arm. The surface of the friction pad that contacts the inner wall of the well casing is curved to increase the friction between the clamping block and the inner wall of the well casing.

[0017] Furthermore, the internal support component includes:

[0018] A lifting ring is slidably sleeved on the outside of the lifting rod. The outside of the lifting ring is provided with an annular groove, and the inside of the annular groove is provided with a hinge ring.

[0019] The inner connecting rod is hinged at one end to the outside of the hinge ring, and at the other end to the outer support arm via the first hinge shaft.

[0020] Furthermore, multiple sets of inner connecting rods are provided on the outside of the hinge ring, each corresponding to one of the outer support arms;

[0022] Furthermore, a lifting buckle is fixedly connected to the upper end of the lifting rod;

[0023] The hook has a hole inside for inserting a steel wire rope.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. This utility model pushes the inner support component downward along the lifting rod. The inner support component drives the outer support component to rotate outward gradually until it presses against the inner wall of the well shaft component. Then, the lifting rod is lifted by the crane hook under the action of the wire rope.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-5 This utility model provides a technical solution:

[0034] Well shaft transport equipment, including:

[0035] The tightening unit 2 includes an outer support assembly 22 that is tightened against the inner wall of the well casing 100 for tightening and limiting the well casing 100, and an inner support assembly 21 disposed on the upper part of the outer support assembly 22 for tensioning and adjusting the outer support assembly 22.

[0036] The lifting unit 1 includes a lifting rod 11 located in the middle of the inner support assembly 21 and the outer support assembly 22, which is used to lift the well shaft component 100 in the top-tightened and limited state. The inner support assembly 21 is slidably located on the outside of the lifting rod 11.

[0037] It should be noted that when lifting and transporting the well shaft component 100, the inner support assembly 21 is pushed downward along the lifting rod 11. The inner support assembly 21 drives the outer support assembly 22 to rotate outward gradually until it is pressed against the inner wall of the well shaft component 100. Then, the lifting rod 11 is lifted by the crane hook under the action of the wire rope. The lifting rod 11 lifts the well shaft component 100 under the action of the friction between the outer support assembly 22 and the well shaft component 100. There is no need to tie the well shaft component 100, and the lifting and transport efficiency is high.

[0038] Furthermore, after the well shaft component 100 is lifted, the well shaft component 100 and the wire rope are connected by a lifting rod 11 and an external support assembly 22, so that when the well shaft component 100 is lifted and lowered, the opening of the well shaft component 100 is in a vertically downward position, and there is no need to manually adjust the orientation angle of the well shaft component 100.

[0039] As an improvement, such as Figure 1-2 , Figure 4 As shown, the external support assembly 22 includes:

[0040] A fixing ring 221 is fixedly connected to the lower end of the lifting rod 11;

[0041] The protruding plate 222 is provided in at least three sets and is fixedly connected to the outside of the fixing ring 221 at equal angles;

[0042] The second hinge shaft 223 is fixedly inserted into the inside of the protrusion 222;

[0043] The outer support arm 224 is hinged at one end to the second hinge shaft 223, and the other end points to the inner wall of the well barrel 100;

[0044] The clamping block 2241 is fixedly connected to one end of the outer support arm 224 relative to the protrusion 222, and is used to clamp the inner wall of the well casing 100.

[0045] Furthermore, such as Figure 1-2 As shown, a friction pad 225 is fixedly connected to one end of the clamping block 2241 relative to the outer support arm 224. The surface of the friction pad 225 that contacts the inner wall of the well casing 100 is set as a curved surface to increase the friction between the clamping block 2241 and the inner wall of the well casing 100.

[0046] Furthermore, such as Figure 2-3 As shown, the inner support assembly 21 includes:

[0047] The lifting ring 211 is slidably sleeved on the outside of the lifting rod 11. The outer side of the lifting ring 211 is provided with an annular groove 2111, and the inside of the annular groove 2111 is provided with a hinge ring 2112.

[0048] The inner connecting rod 212 is hinged at one end to the outside of the hinge ring 2112, and at the other end to the outer support arm 224 via the first hinge shaft 213.

[0049] Among them, the inner connecting rod 212 is provided with multiple sets on the outside of the hinge ring 2112 and corresponds one-to-one with the outer support arm 224;

[0050] The lifting ring 211 has a groove inside for accommodating the end of the inner connecting rod 212.

[0051] In addition, such as Figure 1-2 As shown, a lifting buckle 12 is fixedly connected to the upper end of the lifting rod 11;

[0052] The hook 12 has a hole inside for inserting a wire rope, so that the lower end of the wire rope can pass through the hook 12 and be fastened to the hook 12, and the upper end of the wire rope can be hung on the hook of the crane.

[0053] It should be added that the friction pad 225 in this utility model can be made of rubber, and the outer support arm 224, inner connecting rod 212, and lifting rod 11 are all made of rigid materials.

[0054] It should be noted that: In the initial stage of the implementation of this device, one end of the steel wire rope is tied to the lifting buckle 12, and the other end is hung on the crane hook;

[0055] like Figure 1-5 As shown, when the well casing 100 needs to be hoisted and transported, the lifting unit 1 and the clamping unit 2 are lowered from directly above the well casing 100 into the well casing 100. The lifting ring 211 is pushed downward along the lifting rod 11. The lifting ring 211 pushes the outer support arm 224 to rotate around the second hinge shaft 223 through the inner connecting rod 212, so that the outer support arm 224 gradually switches from the original tightened state to the expanded state. The outer support arm 224 drives the friction pad 225 to clamp against the well casing 100 through the clamping block 2241. The inner wall of the shaft component 100 is then lifted. Subsequently, the crane moves the lifting buckle 12 upward via the wire rope. The lifting buckle 12, through the lifting rod 11, moves the outer support arm 224 upward under the action of the fixing ring 221. The outer support arm 224, through the tightening block 2241, moves the friction pad 225 upward. The friction pad 225, through the friction between itself and the inner wall of the shaft component 100, lifts and transports the shaft component 100. During the entire lifting and transportation process, there is no need to use wire ropes to bind or disassemble the shaft component 100, resulting in high lifting and transportation efficiency.

[0056] like Figure 1-2 As shown, in addition, this utility model uses a rigid lifting rod 11 and an outer support arm 224 to transition the wire rope to the well shaft component 100. During the process of lifting and lowering the well shaft component 100, the opening of the well shaft component 100 is in a vertically downward position, ensuring that the well shaft component 100 is in an upright position when it is lowered to the construction site. There is no need for manual adjustment of the posture of the well shaft component 100, which reduces the risk of hoisting and transportation.
