Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a circular pipe culvert hoisting buckle. Background Art

[0002] Circular culvert is the most commonly used culvert structure type in rural roadbed drainage, with good mechanical properties, simple structure, convenient construction, short construction period and low cost. The most common circular culvert is reinforced concrete circular culvert, which consists of two parts: the tunnel body and the tunnel opening. The tunnel body is the main body of the water passage, mainly composed of the tube body, foundation and joints. The tunnel opening is the connection between the tunnel body, roadbed and water flow. There are two main types of tunnel openings: the eight-shaped wall and the straight wall.

[0003] In the installation construction of circular culverts, cranes and wire ropes are usually used for lifting operations. If the clamping of the circular culvert is not firm enough during lifting, there is a risk of the circular culvert falling during the lifting and moving process.

[0004] The utility model patent with announcement number CN219078836U in the prior art discloses "a highly efficient and safe lifting device for a porous circular culvert", and the technical solution includes:

[0005] A highly efficient and safe lifting device for a porous circular culvert comprises a U-shaped lifting body (1), a stiffening rib (2), a clamping ring (3), a counterweight box (4), a safety anti-skid layer (5), a wire rope buckle (6), and a wire rope (7); wherein the U-shaped lifting body (1) is inserted into a concrete circular culvert and abuts against the inner side of the concrete circular culvert through the safety anti-skid layer (5); the U-shaped lifting body (1) is provided with a plurality of stiffening ribs (2) evenly arranged to enhance its own strength; a clamping ring (3) is arranged at each of the two ends of the upper side of the U-shaped lifting body (1), and the U-shaped lifting body (1) is butted against a lifting device through the clamping ring (3).

[0006] However, the above-mentioned "a highly efficient and safe lifting device for porous circular culvert" still has the following shortcomings in actual use:

[0007] The U-shaped opening of the U-shaped hoisting body does not have a closed structure. The circular culvert being hoisted is prone to displacement on the U-shaped hoisting body when the wire rope moves or shakes due to an accident, making it more difficult to position the pipeline and even creating a risk of falling from a height, which reduces safety.

[0008] Based on this, the applicant considered designing a circular culvert lifting buckle. Utility Model Content

[0009] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide a circular culvert lifting buckle to solve the problem that the hoisted circular culvert is easily displaced on the U-shaped lifting body when the wire rope moves or shakes due to an accident, making the positioning of the pipeline more difficult and even creating the risk of falling from a height.

[0010] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0011] The circular culvert lifting buckle comprises a lifting body, a counterweight body and a closing mechanism, wherein the lifting body comprises a first lifting arm, a second lifting arm and a clamping arm, wherein the first lifting arm and the second lifting arm both have opposite opening ends and clamping ends, and the two ends of the clamping arm are respectively connected to the clamping ends of the first lifting arm and the second lifting arm, so that the first lifting arm, the second lifting arm and the clamping arm are combined to form a horizontal U shape, the counterweight body is installed at the opening end of the first lifting arm, and the closing mechanism is installed in the counterweight body to close the opening between the first lifting arm and the second lifting arm.

[0012] Compared with the prior art, the circular pipe culvert hoisting buckle of the utility model has the following advantages:

[0013] A closed structure is provided between the first boom and the second boom, which can reduce the displacement of the hoisted circular culvert on the hoisting body when the wire rope moves or shakes due to an accident, reduce the difficulty of positioning the circular culvert when unloading, and also reduce the risk of the circular culvert falling from a high altitude during the hoisting process, thereby improving safety.

[0014] The circular culvert hoisting buckle has the advantages of simple structure and easy implementation, is suitable for use in the existing circular culvert hoisting process, and has low use cost and high use efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0030] When implementing: Figure 1 As shown, the circular culvert lifting buckle includes a lifting body 100, a counterweight body 200 and a closing mechanism, the lifting body 100 includes a first lifting arm 110, a second lifting arm 120 and a clamping arm 130, the first lifting arm 110 and the second lifting arm 120 both have opposite opening ends and clamping ends, the two ends of the clamping arm 130 are respectively connected to the clamping ends of the first lifting arm 110 and the second lifting arm 120, so that the first lifting arm 110, the second lifting arm 120 and the clamping arm 130 are combined to form a horizontal U shape, the counterweight body 200 is installed at the open end of the first lifting arm 110, and the closing mechanism is installed in the counterweight body 200, for closing the opening between the first lifting arm 110 and the second lifting arm 120.

[0031] During implementation, the first suspension arm 110 and the second suspension arm 120 are arranged in parallel and located in the same plane.

[0032] Compared with the prior art, the circular culvert hoisting buckle has the following advantages:

[0033] There is a closed structure between the first boom 110 and the second boom 120, which can reduce the displacement of the hoisted circular culvert on the hoisting body 100 when the wire rope moves or shakes due to an accident, reduce the difficulty of positioning the circular culvert when unloading, and also reduce the risk of the circular culvert falling from a high altitude during the hoisting process, thereby improving safety, and the structure is simple and easy to implement, making it suitable for use in the existing circular culvert hoisting process.

[0034] In this embodiment, the closing mechanism includes a first cylinder 300 , which is installed in the counterweight body 200 , and a telescopic end of the first cylinder 300 can be extended to the opening end of the second boom 120 .

[0035] During implementation, the first cylinder 300 is controlled by a single chip microcomputer and a communication chip.

[0036] In this way, the opening between the first boom 110 and the second boom 120 is closed by the telescopic end of the first cylinder 300, which has a simple structure, good sealing stability and good feasibility.

[0037] In this embodiment, a docking groove 121 is formed at the open end of the second suspension arm 120 , and the telescopic end of the first cylinder 300 can dock with the docking groove 121 after being extended.

[0038] In this way, when the circular culvert applies force to the telescopic end of the first cylinder 300 during the lifting process, the docking groove 121 can assist the telescopic end of the first cylinder 300 in bearing force, reduce the load on the telescopic end of the first cylinder 300, and reduce the damage rate of the first cylinder 300.

[0039] In this embodiment, the two ends of the clamping arm 130 are respectively slidably connected to the clamping ends of the first boom 110 and the second boom 120, and the sliding direction of the clamping arm 130 on the first boom 110 is consistent with the length direction of the first boom 110, and the sliding direction of the clamping arm 130 on the second boom 120 is consistent with the length direction of the second boom 120.

[0040] In this way, the load-bearing length on the first boom 110 and the second boom 120 can be changed by changing the relative position between the clamping arm 130 and the first boom 110 and the second boom 120, so as to better clamp the circular culverts with different pipe lengths and improve the lifting stability and positioning accuracy.

[0041] In this embodiment, sliders 131 are provided at both ends of the clamping arm 130, and sliding cavities are provided in the clamping ends of the first suspension arm 110 and the second suspension arm 120. The sliding directions of the two sliding cavities are consistent with the length directions of the corresponding first suspension arm 110 and the second suspension arm 120, and the two sliders 131 are slidably connected to the two sliding cavities one by one.

[0042] During implementation, tracks are provided on the two sliding cavities, and the openings of the two tracks are arranged opposite to each other.

[0043] In this way, the sliding between the clamping arm 130 and the first suspension arm 110 and the second suspension arm 120 is achieved through the sliding connection between the slider 131 and the sliding cavity, which has a simple structure, high feasibility and stability, and low manufacturing cost.

[0044] In this embodiment, a second cylinder 400 is further included. There are two second cylinders 400, which are respectively fixed to the clamping ends of the first boom 110 and the second boom 120. The two second cylinders 400 are transmission-connected to the two sliders 131 one by one, and the transmission directions of the two second cylinders 400 are consistent with the sliding directions of the corresponding sliders 131.

[0045] During implementation, the first cylinder 300 is controlled by a single chip microcomputer and a communication chip.

[0046] In this way, the pushing control of the clamping arm 130 is realized by the second cylinder 400, the pushing structure is simple, and the reliability and controllability are good.

[0047] In this embodiment, a pair of limiting clamp arms 132 are provided at both ends of the clamping arm 130 , and each pair of limiting clamp arms 132 is slidably connected to the outer wall of the first suspension arm 110 and the second suspension arm 120 in a one-to-one correspondence.

[0048] During implementation, the limiting clamp arm 132 only limits the clamping arm 130 in the width direction and the height direction of the first suspension arm 110 and the second suspension arm 120 .

[0049] In this way, the limiting clamp arm 132 can enhance the connection strength between the clamping arm 130 and the first arm 110 and the second arm 120 , and can also enable the clamping arm 130 to slide along the length direction of the first arm 110 and the second arm 120 when the second cylinder 400 pushes the slider 131 .

[0050] In this embodiment, a plurality of stiffening ribs 500 are disposed on the first suspension arm 110 and the second suspension arm 120 , and the plurality of stiffening ribs 500 are arranged in an array along the length direction of the first suspension arm 110 and the second suspension arm 120 .

[0051] In this way, the stiffening rib 500 can concentrate the gravity of the circular culvert onto the first suspension arm 110 and the second suspension arm 120 , thereby improving the load-bearing reliability of the first suspension arm 110 and the second suspension arm 120 .

[0052] In this embodiment, an anti-slip layer 600 is disposed on the outer wall of the open end of the second suspension arm 120 .

[0053] In this way, during the hoisting process, the anti-slip layer 600 can increase the friction between the second lifting arm 120 and the circular culvert, thereby reducing the risk of displacement of the circular culvert and falling from a high altitude.

[0054] In this embodiment, two lifting rings 700 are arranged side by side on the top of the outer wall of the first lifting arm 110 .

[0055] In this way, the entire hoisting body 100 can be hoisted by the two hoisting rings 700. The two hoisting rings 700 make the hoisting force on the first hoisting arm uniform and not prone to tilting.

[0056] The use process of the utility model circular pipe culvert hoisting buckle is as follows:

[0057] The first step is to align the opening ends of the first suspension arm 110 and the second suspension arm 120 on the suspension body 100 with one end of the circular culvert to be suspended;

[0058] The second step is to control the hoisting body 100 to move the second hoisting arm 120 into the pipe of the circular culvert.

[0059] The third step is to start the first cylinder 300 so that the telescopic end of the first cylinder 300 is extended to close the opening formed between the opening ends of the first boom 110 and the second boom 120.

[0060] Step 4: Use the second lifting arm 120 to lift the circular culvert;

[0061] During the above use, when the specifications of the hoisted circular culvert need to be changed, the second cylinder 400 can be used to control the relative position between the clamping arm 130 and the first and second arms 110 and 120 to change the load-bearing lengths on the first and second arms 110 and 120, thereby improving the clamping stability of the hoisting.

[0062] The above are only preferred implementations of the present invention. It should be pointed out that a number of modifications and improved technical solutions made by those skilled in the art without departing from the technical solution should also be deemed to fall within the scope of protection required by the claims.
