Description

Technical Field

[0001] This utility model relates to a pipe hoisting auxiliary device, and more particularly to a ductile iron pipe hoisting auxiliary device. Background Technology

[0002] Ductile iron pipes are mainly used for water transportation and have a wide range of applications in water conservancy projects. When installing ductile iron pipes, they need to be lowered into the trench of the water supply pipeline to secure them.

[0003] Currently, the installation of ductile iron pipes typically involves hoisting them from transport vehicles into trenches. This process requires two hooks to be attached to both ends of the pipe, with the hooks connected to the hoisting body via wire or chain. The hoisting body is then connected to a crane, which moves the hoisting body, thus moving the ductile iron pipe. However, in practice, the large boom of the hoisting equipment limits the precise adjustment of the lifting and lowering positions, making operation inflexible and inconvenient, resulting in suboptimal performance. Therefore, manual adjustments are often necessary when the pipe is near the designated position, leading to excessively long hoisting times. Furthermore, the existing hoisting process relies solely on the hooked area for stress on the ductile iron pipe, increasing the risk of excessive stress at a single point, which can cause deformation or damage.

[0004] To address these technical problems, an auxiliary device for hoisting ductile iron pipes is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device for hoisting ductile iron pipes, which solves the problem that existing ductile iron pipes cannot be precisely adjusted when hoisted to the vicinity of a set position; and the problem that simply using a hook for hoisting can easily lead to deformation or damage of the ductile iron pipes due to excessive force at a single point.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A hoisting auxiliary device for ductile iron pipes includes:

[0008] The mounting plate is divided into a left half and a right half; the right end of the mounting plate has a downward bending section, and a vertical baffle is fixed on the lower surface of the middle part; the drive motor passes horizontally through the bending section and is connected to one end of a horizontal screw, and the other end of the horizontal screw is rotatably mounted on the vertical baffle.

[0009] A sliding block is threadedly fitted onto a horizontal screw rod, with its upper surface flush with the lower surface of the mounting plate. A telescopic cylinder is vertically mounted on the lower surface of the telescopic cylinder. An air pump is fixed to the piston rod of the telescopic cylinder, and a horizontal connecting rod is fixed to the side facing the vertical baffle. The horizontal connecting rod connects to a mounting rod perpendicular to the horizontal screw rod, which is horizontally positioned. A mounting cylinder is fixed to each end of the mounting rod, and a hollow air guide rod runs vertically through the interior of each cylinder. A horizontal support plate is located at the top and bottom of the air guide rod. Oppositely positioned pneumatic telescopic columns are located on the facing surfaces of the two support plates on the same air guide rod, and these columns are connected to the air guide rod. The air pump is connected to the air guide rod after passing through the mounting cylinder via an air transmission pipe. A valve is also provided on the air transmission pipe.

[0010] The left and right halves of the mounting plate are symmetrically arranged about the center line of the mounting plate.

[0011] Specifically, the valve is a push-pull valve; each end of the mounting rod is hinged with a swing rod that rotates in the horizontal direction, and a transmission rod is hinged to the swing rod. The transmission rod is connected to the valve stem of the push-pull valve and adjusts the opening and closing of the push-pull valve through the valve stem.

[0012] Specifically, a lifting shell is fixed to the right end of the mounting plate, and the lifting shell is provided with vertical lifting lugs.

[0013] Furthermore, horizontal support rods are fixedly installed inside the vertical lifting lugs on both sides of the mounting plate; it also includes an inverted Y-shaped lifting frame, with the support rods fixedly installed in the bottom opening of the lifting frame; the top of the lifting frame also has a lifting hole.

[0014] Specifically, a horizontal take-up roller is rotatably installed between the two vertical baffles. A lifting rope is wound around the take-up roller, which is driven to rotate by a take-up motor fixed to the vertical baffles.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes the cooperation between a horizontal screw and a drive motor to enable a sliding block to drive a ductile iron pipe to achieve slow, minute horizontal movement. A vertically positioned telescopic cylinder enables the ductile iron pipe to achieve slow, minute vertical movement, thus achieving precise adjustment of the pipe's installation position. A pneumatic telescopic column clamps the ductile iron pipe from both above and below, optimizing the force distribution at the clamping points. The pneumatic clamping method also allows for adjustment of the clamping force by adjusting the air pump pressure, preventing damage or deformation caused by excessive force on the ductile iron pipe.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0025] like Figures 1-3 As shown, this utility model discloses an auxiliary device for hoisting ductile iron pipes, comprising:

[0026] Mounting plate 1 is divided into a left half and a right half; the right end of the mounting plate is provided with a downward bending section 101, and a vertical baffle 102 is fixed on the lower surface of the middle part; the drive motor 103 passes horizontally through the bending section 101 and is connected to one end of the horizontal screw 104, and the other end of the horizontal screw 104 is rotatably mounted on the vertical baffle 102.

[0027] A sliding block 201 is threadedly fitted onto a horizontal screw rod 104, with its upper surface flush with the lower surface of the mounting plate 1. A telescopic cylinder 202 is vertically mounted on the lower surface. An air pump 301 is fixed to the piston rod of the telescopic cylinder 202, and a horizontal connecting rod 302 is fixed to the side facing the vertical baffle 102. A mounting rod 303 perpendicular to the horizontal screw rod 104 is connected to the horizontal connecting rod 302. The mounting rod 303 is horizontally positioned, and a mounting cylinder 304 is fixed to each end of the mounting rod 303. A hollow air guide rod 305 is vertically inserted inside the mounting cylinder 304. A horizontal support plate 306 is provided at the top and bottom of the air guide rod 305. Opposite surfaces of the two support plates 306 on the same air guide rod 305 are provided with opposing pneumatic telescopic columns 307, which are connected to the air guide rod 305. The air pump 301 is connected to the air guide rod 305 after passing through the side wall of the mounting cylinder 304 via an air transmission pipe 308. A valve 309 is also provided on the air transmission pipe 308.

[0028] The left and right halves of the mounting plate 1 are symmetrically arranged about the center line of the mounting plate 1.

[0029] The main principle of this utility model is as follows: Figure 1 and Figure 2 As shown, in actual use, the horizontal screw 104 is rotated by the drive motor 103, thereby adjusting the position of the sliding block 201 on the horizontal screw 104. In the initial state, the two sliding blocks 201 on the mounting plate 1 move back to back, thereby moving the pneumatic telescopic column 307 at the bottom of the sliding block 201 to both ends of the ductile iron pipe. By controlling the extension of the telescopic cylinder 202, the pneumatic telescopic column 307 is moved to the same height as the end of the ductile iron pipe. Then, the sliding blocks 201 are moved towards each other by the drive motor 103, thereby moving the pneumatic telescopic column 307 to the outside of both ends of the ductile iron pipe, so that the end of the ductile iron pipe is located between the four pneumatic telescopic columns 307. The air pump 301 fills the air transmission pipe 308 with air, and the control valve 309 is opened. The air is transmitted along the air guide rod 305 to the pneumatic telescopic columns 307 on the upper and lower sides, and the pneumatic telescopic column 307 is extended to achieve clamping of the ductile iron pipe. Then, the mounting plate 1 is lifted using external hoisting equipment such as a truck crane, thereby moving the ductile iron pipe to the vicinity of the installation point. Through the cooperation of the drive motor 103 and the telescopic cylinder 202, the installation position of the ductile iron pipe is fine-tuned. During this process, the output air pressure of the air pump 301 needs to be calculated in advance to ensure that the pneumatic telescopic column 307 can stably clamp the ductile iron pipe without damaging it. The valve 309 can be a solenoid valve or an electric valve, which controls the opening and closing of the gas passage.

[0030] In a preferred embodiment, the valve 309 is a push-pull valve; each end of the mounting rod 303 is hinged with a swing rod 401 that rotates in the horizontal direction, and a transmission rod 402 is hinged on the swing rod 401. The transmission rod 402 is connected to the valve stem 403 of the push-pull valve 309, and the opening and closing of the push-pull valve 309 is adjusted through the valve stem 403.

[0031] In this embodiment, another option for valve 309 is provided, specifically, as follows: Figure 3 As shown, in this embodiment, valve 309 is a push-pull valve, meaning that the valve structure achieves the relative position between the valve port and the valve block by controlling the movement of the valve stem 403. When the valve port aligns with the internal channel on the valve block, gas can flow through the valve block, thus achieving gas path connection. When the swing rod 401 contacts the end of the ductile iron pipe, that is, when the pneumatic telescopic column 307 is located in the clamping position outside the end of the ductile iron pipe, the swing rod 401 is pushed by the pipe wall of the ductile iron pipe, which in turn drives the valve stem 403 of valve 309 to move through the transmission rod 402, thereby changing the push-pull valve from a closed state to a flowing state. This allows the air pump 301 to fill the pneumatic telescopic column 307 with gas, causing the pneumatic telescopic column 307 to extend and clamp the ductile iron pipe. During this process, since the swing rod 401 is always under pressure, it can be ensured that the air pump 301 can continuously fill the pneumatic telescopic column 307 with air, so that the clamping force remains stable, the stability of the clamping is enhanced, and the ductile iron pipe is prevented from slipping.

[0032] In a preferred embodiment, a lifting shell 105 is also fixed to the right end of the mounting plate 1, and the lifting shell 105 is provided with a vertical lifting lug 106.

[0033] In this embodiment, as Figure 1 and Figure 2 By setting a lifting shell 105 on the mounting plate 1, external lifting tools such as truck cranes can be lifted onto the two vertical lifting lugs 106 at the left and right ends of the mounting plate 1 during lifting, thereby ensuring that the forces on both sides of the mounting plate 1 are balanced during the lifting process and ensuring the stability of the ductile iron pipe during the lifting and transportation process.

[0034] As a further embodiment, horizontal support rods 107 are fixedly installed inside the vertical lifting lugs 106 on the left and right sides of the mounting plate 1; it also includes an inverted Y-shaped lifting frame 108, with the support rods 107 fixedly installed in the bottom opening of the lifting frame 108; the top of the lifting frame 108 also has a lifting hole.

[0035] In this embodiment, a further structure is provided to enhance stability during the hoisting process. Specifically, as follows: Figure 1 and Figure 2As shown, two vertical lifting lugs 106 are connected by a bearing rod 107. After passing through the vertical lifting lugs 106, both ends of the bearing rod 107 are fixedly connected to the lifting frame 108. When lifting with external lifting tools, it is directly connected to the lifting hole of the lifting frame 108, so that the entire lifting structure is connected with the device of this utility model as a whole. The bearing rod 107 can effectively optimize the stress on both sides of the mounting plate 1, making the entire lifting process more stable.

[0036] In a preferred embodiment, a horizontal take-up roller 109 is rotatably provided between the two vertical baffles 102. A lifting rope is wound around the take-up roller 109, and the take-up roller 109 is driven to rotate by a take-up motor fixed on the vertical baffles 102.

[0037] In this embodiment, a structure for assisting in fixing ductile iron pipes is provided, specifically, as follows: Figure 1 As shown, the winding roller 109 is driven to rotate by a winding motor. By rotating the winding roller 109, the lifting rope wound on the winding roller 109 can be wound up and down. The lifting rope is used to wrap around the middle of the ductile iron pipe, thereby helping to stabilize the ductile iron pipe. At the same time, it can also play an auxiliary lifting role during the extension and retraction of the telescopic cylinder 202.
