Description

Technical Field

[0001] The utility model relates to the field of handling of drainage pipes in a pumping station, and specifically refers to a device for handling drainage pipes in a pumping station. Background Technique

[0002] A pumping station is a device and project that can provide hydraulic power and pneumatic power with a certain pressure and flow rate, called pumps and pumping station projects. Generally, some drainage pipe fittings are reserved in the pumping station for maintenance and emergency use.

[0003] The drainage pipe fittings in the pumping station are very heavy pipe bodies. Generally, for storage, they are placed on the placement racks section by section. When handling is required, due to the heavy pipe bodies, it is very laborious. During handling, a trolley can be used to freely move on the ground, but for lifting the pipe fittings between the trolley and the rack, many people are still needed for handling, which is still very strenuous. Also, considering the relatively heavy pipe fittings themselves, if too many people participate in handling and the pipe fittings accidentally fall if they slip out of hand, it is very likely to cause harm to personnel. Therefore, a device for handling drainage pipes in a pumping station is needed. Content of the Utility Model

[0004] I. Technical Problems to be Solved

[0005] The technical problem to be solved by the utility model is that when handling drainage pipes in a pumping station, a trolley can be used, but the structure and function of the trolley are relatively single, and many people are still needed for handling when lifting the pipe fittings up and down.

[0006] II. Technical Solution

[0007] To solve the above technical problems, the technical solution provided by the utility model is: a device for handling drainage pipes in a pumping station, including a vehicle body, and universal wheels are connected and arranged below the vehicle body.

[0008] A control box is connected and arranged on one side of the vehicle body. A screw rod is rotatably connected in the control box. A first motor matched with the screw rod is connected to one end of the control box. The external thread structures at both ends of the screw rod are arranged in opposite directions. Driving blocks with internal thread structures are connected to both ends of the screw rod. A support is connected above the control box. A telescopic frame is rotatably connected between the driving block and the support. A limiting mechanism matched with the screw rod is connected inside the bottom of the control box. A plurality of bearing frames are rotatably connected above the support. A guiding mechanism matched with the bearing frame is connected inside the support.

[0009] Further, the guiding mechanism includes a transmission shaft which is rotatably connected inside the bracket. A second motor cooperating with the transmission shaft is connected inside the bracket. At both ends of the top of the bracket, a first support shaft and a second support shaft are respectively rotatably connected. The carrier is connected to the first support shaft and the second support shaft. A chain-slot chain transmission mechanism is commonly connected between the end of the transmission shaft and the first support shaft. By operating the second motor, the carrier rotates, facilitating the removal of the drainage pipe fitting from the device.

[0010] Further, the limiting mechanism includes a limiting slide rail which is arranged inside the bottom of the control box. A third support block is connected to the bottom of the driving block. A pulley cooperating with the limiting slide rail is rotatably connected to the third support block. The thickness of the pulley matches the width of the limiting slide rail. On the one hand, it provides limit adjustment for the movement of the driving block on the screw rod. On the other hand, it also provides a supporting effect for the driving block and the bracket, relieving the pressure borne by the screw rod.

[0011] Further, an armrest frame is connected to one side of the vehicle body. The support rods in the armrest frame are all hollow tube bodies. Considering that a single drainage pipe itself has a large mass, when many drainage pipes are placed on the vehicle body for handling, manual pushing and pulling may consume a lot of effort. Therefore, the auxiliary component of the armrest frame is welded together with hollow pipe fittings to minimize the overall weight of the handling vehicle body as much as possible.

[0012] Further, the telescopic frame includes a first support block and a second support block. The first support block is arranged on the top of the driving block. The second support block is arranged at both ends below the bracket. A support rod is rotatably connected between the first support block and the second support block. Through the telescopic frame composed of the above components, it can cooperate with the rotation of the screw rod to lift and lower the drainage pipe fittings carried on the bracket on the vehicle body.

[0013] III. Beneficial Effects

[0014] The advantages of the present utility model compared with the prior art are as follows: The device is upgraded and improved on the handling trolley. By providing a lifting mechanism, it overcomes the difficulty of inconvenient handling due to the height difference between the vehicle body and the pipe rack. And the end of the carrier pipe fitting can be rotated to a certain extent, which better cooperates with the upgraded lifting mechanism to load and unload the pipe fitting. Through the above mechanisms, the handling of the pump station drainage pipe fitting only requires a small amount of human participation to be easily realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0021] Embodiment 1

[0022] In combination with the attached Figures 1-4 , to solve the above technical problems, the technical solution provided by the present utility model is: A handling device for the drainage pipe of a pumping station, including a vehicle body 1, a universal wheel 19 is connected and arranged below the vehicle body 1, a handrail frame 20 is connected and arranged on one side of the vehicle body 1, and the support rods in the handrail frame 20 are all arranged as hollow pipe bodies. Considering that a single drainage pipe itself has a large mass, when a lot of drainage pipes are placed on the vehicle body 1 for handling, manual pushing and pulling may consume a lot of effort. Therefore, the auxiliary component of the handrail frame 20 is welded together with hollow pipe fittings to minimize the overall weight of the handling vehicle body 1 as much as possible. A bracket 9 is connected and arranged above one side of the vehicle body 1, a plurality of carrying racks 15 are rotatably connected and arranged above the bracket 9, a guiding mechanism matched with the carrying rack 15 is connected in the bracket 9, the guiding mechanism includes a transmission shaft 10, the transmission shaft 10 is rotatably connected and arranged in the bracket 9, a second motor 11 matched with the transmission shaft 10 is connected in the bracket 9, a first support shaft 12 and a second support shaft 14 are respectively rotatably connected and arranged at both ends of the top of the bracket 9, the carrying rack 15 is connected and arranged on the first support shaft 12 and the second support shaft 14, and a chain groove and chain transmission mechanism 13 is jointly connected between the end of the transmission shaft 10 and the first support shaft 12. By operating the second motor 11, the carrying rack 15 rotates to facilitate the unloading of the drainage pipe fittings from the device.

[0023] The drainage pipe fittings that are loaded and unloaded between the handling device and the drainage pipe fitting storage rack are received by the carrier 15. The carrier 15 is arranged in an arc shape, which fits as closely as possible to the outer contour of the drainage pipe fittings, helping to stabilize the pipe fittings. A set of carriers 15 are installed on each of the support shafts one 12 and support shafts two 14 on the bracket 9. By supporting both ends of the pipe fitting, the pipe fitting is lifted. Through the operation of the second motor 11, the transmission shaft 10 rotates. The second motor 11 is fixed at the central position of the bracket 9 and is a motor with bidirectional output. The transmission shaft 10 can be understood as two shaft parts here, which are respectively connected to the power output shafts at both ends of the second motor 11. Through the chain groove and chain transmission mechanism 13, the support shaft one 12 rotates synchronously with the transmission shaft 10. In this way, the carrier 15 can rotate slightly towards one side, facilitating the unloading of heavier pipe fittings from the bracket 9. The adjacent support shaft two 14 can also rotate on the bracket 9. Through the rotation of the pipe fitting, it can also rotate accordingly without affecting the normal use of the guiding mechanism.

[0024] Embodiment 2

[0025] Combined with the attached Figure 1 、attached Figure 2 and attached Figure 4 , a control box 2 is connected and provided on one side of the vehicle body 1. A screw rod 3 is rotatably connected in the control box 2. A first motor 4 that cooperates with the screw rod 3 is connected and provided at one end of the control box 2. The external thread structures at both ends of the screw rod 3 are arranged in opposite directions. Driving blocks 5 with internal thread structures are connected to both ends of the screw rod 3. A bracket 9 is connected and provided above the control box 2. A telescopic frame is rotatably connected between the driving block 5 and the bracket 9. The telescopic frame includes a support block one and a support block two. The support block one is arranged at the top of the driving block 5. The support block two is arranged at both lower ends of the bracket 9. A support rod 7 is rotatably connected between the support block one and the support block two. Through the telescopic frame composed of the above components, it can cooperate with the rotation of the screw rod 3 to make the drainage pipe fittings carried on the bracket 9 move up and down on the vehicle body 1. A limiting mechanism that cooperates with the screw rod 3 is connected inside the bottom of the control box 2. The limiting mechanism includes a limiting slide rail 18. The limiting slide rail 18 is arranged inside the bottom of the control box 2. A support block three is connected to the bottom of the driving block 5. A pulley 17 that cooperates with the limiting slide rail 18 is rotatably connected to the support block three. The thickness of the pulley 17 is matched with the width of the limiting slide rail 18. On the one hand, it provides limit adjustment for the movement of the driving block 5 on the screw rod 3, and on the other hand, it also provides a supporting effect for the driving block 5 and the bracket 9, alleviating the pressure borne by the screw rod 3.

[0026] Through the operation of the first motor 4, the screw 3 rotates. Under the cooperation of the thread structure and the limiting conditions existing between the above-mentioned overall structures, the driving blocks 5 at both ends approach or move away from each other. Through the structural design of the telescopic frame, the bracket 9 carrying the drainage pipe fitting is lifted and lowered on the vehicle body 1, so as to facilitate the drainage pipe fitting to be lowered after being taken off from the storage rack at a higher position and placed into the vehicle body 1. On the contrary, it is also possible to pick up the pipe fitting from the vehicle body 1 and lift it to a suitable position on the storage rack. Since the device has a lifting mechanism and can transport the pipe fitting to any height within a certain range, in addition to setting a vehicle board on the vehicle body 1, multi-layer mounting racks can also be set on the vehicle board according to the on-site objective requirements for easy and quick handling and use.

[0027] When the present utility model is specifically implemented and this device is used, the vehicle body 1 is pushed to the side of the placement rack for the drainage pipe fittings of the pumping station, and the side with the bracket 9 is close to the placement rack. Then, through the operation of the first motor 4, the lifting mechanism raises the bracket 9 until it is beside the drain pipe to be removed. The position of the carrier 15 on the bracket 9 is slightly lower than the position of the drain pipe. The outer contour of the drainage pipe fitting is cylindrical in itself, and it will move with a slight push by hand. Slowly move it to the carrier 15 and place it well, which is not particularly laborious. After the bracket 9 obtains the drainage pipe fitting, under the action of the lifting mechanism, it slowly descends to the position on the vehicle body 1 for placing the pipe fitting. Through the operation of the second motor 11, the carrier 15 is slightly tilted towards the vehicle board or the vehicle frame side, so that the pipe fitting does not roll down directly due to gravity. Then, with the assistance of hand, push the pipe fitting towards the vehicle body 1 direction, and the pipe fitting can be easily unloaded onto the vehicle body 1. If the drainage pipe fitting carried on the vehicle body 1 is to be placed on the pipe rack of the pumping station, the reverse operation can be performed. The drainage pipe fitting can be conveniently transported, loaded and unloaded through the vehicle body 1 without particularly consuming the physical strength of the handling personnel.

[0028] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
